1.	Berg, Thomas, et al. (författare) The Effect of Study Design and Analysis Methods on Recovery Rates in Bell's Palsy 2009 Ingår i: The Laryngoscope. - : Wiley. - 0023-852X .- 1531-4995. ; 119:10, s. 2046-2050 Tidskriftsartikel (refereegranskat)abstract Objectives/Hypothesis: We investigated how study design affects the rate of recovery in Bell's palsy. Study Design: Prospective, randomized, double-blind, placebo-controlled, multicenter trial. Methods: Data were extracted from the Scandinavian Bell's palsy study, which included 829 patients. The study design was factorial; 416 patients given prednisolone, 413 not given prednisolone, 413 patients given valacyclovir, 416 not given valacyclovir. Data were analyzed with intention-to-treat principle and complete-case analysis methods and recovery was defined as Sunnybrook score 100, House-Brackmann grade I or <= grade II at 12 months. Results: With the intention-to-treat principle and last-observation-carried-forward method (n = 829) and recovery defined as Sunnybrook 100, 300 of the 416 patients (72%) receiving prednisolone had recovered compared with 237 of the 413 (57%) who did not receive prednisolone (P < .0001). With recovery defined as House-Brackmann grade 1, the corresponding recovery rates were 324 of 416 (78%) and 266 of 413 (64%) (P < .0001). With complete-case analysis and recovery defined House-Brackmann grade I (n = 782), 335 of 389 patients (86%) given prednisolone recovered compared with 277 of 393 (70%) in the group not given prednisolone (P < .0001). With recovery defined as House-Brackmann <= grade II (n = 797), the corresponding recovery rates were 380 of 396 (96%) and 353 of 401 (88%) (P < .0001). The analysis method affected the recovery rates in the valacyclovir and no-valacyclovir groups in a similar way as in the prednisolone and no-prednisolone groups. Conclusions: Recovery rates in a Bell's palsy study are substantially affected by the choice of analysis method and definition of recovery.

3.	Brodin, Thomas, et al. (författare) Antimüllerian hormone levels are strongly associated with live-birth rates after assisted reproduction 2013 Ingår i: Journal of Clinical Endocrinology and Metabolism. - : The Endocrine Society. - 0021-972X .- 1945-7197. ; 98:3, s. 1107-1114 Tidskriftsartikel (refereegranskat)abstract Context: Previous studies have suggested that antimullerian hormone (AMH) levels are positively associated with in vitro fertilization (IVF) outcome through their relationship with oocyte yield and not by reflecting oocyte or embryo quality. Objective: The aim was to investigate whether AMH levels are associated with pregnancy and live-birth rates and whether the results may also reflect qualitative aspects of oocytes and embryos. Design: The study was a prospective cohort study between April 2008 and June 2011. Setting: The study was done at a university-affiliated private infertility center. Patients: The study cohort consisted of 892 consecutive women undergoing 1230 IVF-intracytoplasmic sperm injection cycles. Intervention(s): AMH levels, analyzed using the DSL ELISA kit, were statistically adjusted for repeated treatments and age and analyzed for associations with treatment outcome. Main Outcome Measures: Pregnancy rates, live-birth rates, and stimulation outcome parameters were measured. Results: AMH was log-normally distributed with a mean (SD) of 2.3 (2.5) ng/mL. Live-birth rates per started cycle (mean [95% confidence interval]) increased log-linearly from 10.7% [7.2-14.1] for AMH < 0.84 ng/mL (25th percentile) to 30.8% [25.7-36.0] for AMH > 2.94 ng/mL (75th percentile), P-trend < .0001, being superior in women with polycystic ovaries. These findings were significant also after adjustments were made for age and oocyte yield. AMH was also associated with ovarian response variables and embryo scores. Conclusions: AMH is strongly associated with live-birth rates after IVF-intracytoplasmic sperm injection. AMH may therefore serve as a prognostic factor for the chance of a pregnancy and live birth. Treatment outcome was superior in patients with polycystic ovaries. The findings also indicate that AMH may partially comprise information about oocyte quality.

5.	Brodin, Thomas, et al. (författare) Comparing four ovarian reserve markers : associations with ovarian response and live births after assisted reproduction 2015 Ingår i: Acta Obstetricia et Gynecologica Scandinavica. - : Wiley. - 0001-6349 .- 1600-0412. ; 94:10, s. 1056-1063 Tidskriftsartikel (refereegranskat)abstract Introduction. We compared the ability of four different ovarian reserve tests (ORTs) to predict live births per started in vitro fertilization-intracytoplasmic sperm injection (IVF-ICSI) cycle, and poor and excessive response to controlled ovarian hyperstimulation. Material and methods. This was a cohort study in a private infertility center in collaboration with Uppsala University, comprising 1230 IVF-ICSI cycles in 892 consecutive women between April 2008 and June 2011. Anti-Mullerian hormone (AMH) levels, antral follicle counts (AFC), combinations of basal levels of follicle-stimulating hormone and luteinizing hormone, and menstrual cycle lengths were analyzed for correlation and treatment outcome prediction in age-adjusted statistical models. Stepwise multivariable generalized estimating equation analyses were carried out in a sub-group with complete data on all four ORTs (620 cycles in 443 women). Odds ratios and c-statistics were calculated in the largest available set of data for each significant variable. Primary outcomes were live birth rate per started cycle and poor and excessive ovarian response to controlled ovarian hyperstimulation (defined by the ovarian sensitivity index). Results. All ORTs correlated significantly with each other, with the strongest correlation between AFC and AMH (r = 0.71, p < 0.0001). Univariately, AMH and age equivalently predicted live birth (c-statistic 0.61), and together they provided a significantly better model (c-statistic 0.64). For prediction of poor and excessive response the best model included AMH, AFC and age (c-statistic 0.89). Conclusions. AMH improves the ability to estimate live birth rates after assisted reproduction compared with female age alone. AMH, AFC and age together constituted the best model for prediction of ovarian response.
6.	Brodin, Thomas, et al. (författare) High basal LH levels in combination with low basal FSH levels are associated with high success rates at assisted reproduction 2009 Ingår i: Human Reproduction. - : Oxford University Press (OUP). - 0268-1161 .- 1460-2350. ; 24:11, s. 2755-2759 Tidskriftsartikel (refereegranskat)abstract BACKGROUND The objective of this study was to evaluate the associations of basal gonadotrophins with pregnancy and delivery rates at IVF/ICSI. METHODS A prospective observational study was conducted at a university-affiliated private infertility centre. Patients were 745 women, who underwent 1328 IVF/ICSI treatment cycles. Basal FSH, basal LH and combinations of FSH and LH versus treatment data and pregnancy and delivery rates were measured. RESULTS Combinations of FSH and LH gave significantly better information than the LH:FSH ratio, or each gonadotrophin alone: highest mean pregnancy rate (39%) was achieved in women with low FSH (<6.7 U/l) and with high LH levels (>4.9 U/l), whereas pregnancy rate was lowest (22%) in women with high FSH and low LH levels. Pregnancy rates were intermediate (27-28%) if FSH and LH were either both low or both high (P for trend = 0.0004). Associations to delivery rates and measures of ovarian response and embryo quality followed the same pattern. CONCLUSIONS Basal LH modifies and improves the information given by basal FSH alone. Low FSH level combined with high LH probably reflects a well-preserved ovarian reserve and is associated with the highest success rates at IVF/ICSI.
7.	Brodin, Thomas, et al. (författare) Menstrual cycle length is an age-independent marker of female fertility : results from 6271 treatment cycles of in vitro fertilization 2008 Ingår i: Fertility and Sterility. - : Elsevier BV. - 0015-0282 .- 1556-5653. ; 90:5, s. 1656-1661 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: To investigate whether menstrual cycle length correlates with success rates at IVF/intracytoplasmic sperm injection (ICSI) and could be used as a marker of ovarian reserve. DESIGN: Prospective observational study. SETTING: Private infertility centre. PATIENT(S): A total of 6271 IVF/ICSI treatment cycles. INTERVENTION(S): Self-reported mean number of menstrual days during the last year was recorded before initiation of IVF/ICSI treatment. MAIN OUTCOME MEASURE(S): Relations between menstrual cycle length and pregnancy and delivery rates. RESULT(S): Increasing age was associated with a subtle shortening of mean menstrual cycle length. Menstrual cycle length correlated linearly with pregnancy and delivery rates, even after age adjustment. The chance of delivery after IVF/ICSI was almost doubled for women with a menstrual cycle length >34 days compared with women with a menstrual cycle length <26 days. Menstrual cycle length was also significantly associated with ovarian response to FSH/hMG stimulation and embryo quality. CONCLUSION(S): Mean menstrual cycle length is highly related to success rates in assisted reproduction, independently of age. A precise menstrual cycle history could be used as a simple marker of ovarian reserve.
8.	Bylund, Nina, et al. (författare) Synkinesis in Bell's palsy in a randomised controlled trial 2017 Ingår i: Clinical Otolaryngology. - : Wiley. - 1749-4478 .- 1365-2273. ; 42:3, s. 673-680 Tidskriftsartikel (refereegranskat)abstract OBJECTIVES: To study the development of synkinesis in Bell's palsy. Frequency, severity, gender aspects and predictors were analysed.DESIGN: Data from the randomised controlled Scandinavian Bell's palsy trial including 829 patients.MAIN OUTCOME MEASURES: Frequency and severity of synkinesis at 12 months were the main outcome measures. Mean Sunnybrook synkinesis scores, voluntary movement scores and composite scores between 6 and 12 months were compared.RESULTS: In 743 patients with a 12-month follow-up, synkinesis frequency was 21.3%. There was no gender difference. Synkinesis was moderate to severe in 6.6% of patients. Those with synkinesis at 6 months had a synkinesis score of 4.1 (±2.8 sd), which increased to 4.7 (±3.2) (P = 0.047) at 12 months (n = 93). Sunnybrook composite score at 1 month was the best predictor for synkinesis development with receiver operating characteristics and area under the curve (AUC) 0.87. Risk for synkinesis increased with a lower Sunnybrook composite score. Furthermore, at 1 month, symmetry of voluntary movement had higher predictive value for synkinesis than resting symmetry with AUC 0.87 and 0.77, respectively. Gentle eye closure and open-mouth smile were the only independent significant predictive items (AUC 0.86).CONCLUSIONS: Moderate-to-severe synkinesis was present in 6.6% of patients. The mean synkinesis score increased between 6 and 12 months, and outcome should therefore be evaluated after at least 12 months. Sunnybrook composite score and symmetry of voluntary movement at 1 month were good predictors for synkinesis.

(författare) Myocardial Infarction with Non-Obstructive Coronary Arteries : The Importance of Achieving Secondary Prevention Targets 2018 Ingår i: American Journal of Medicine. - : Elsevier. - 0002-9343 .- 1555-7162. ; 131:5, s. 524-531 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Around 5-10% of all myocardial infarction patients have non-obstructive coronary arteries. Studies investigating the importance of follow-up and achievement of conventional secondary prevention targets in these patients are lacking.METHODS: In this analysis from the SWEDEHEART registry, we investigated 5830 myocardial infarction patients with non-obstructive coronary arteries (group 1) and 54,637 myocardial infarction patients with significant coronary artery disease (≥50% stenosis; group 2). Multivariable- and propensity score-adjusted statistics were used to assess the reduction in the one-year risk of major adverse events associated with prespecified secondary preventive measures: participation in follow-up at 6-10 weeks after the hospitalization; achievement of secondary prevention targets (blood pressure and low-density lipoprotein cholesterol levels in the target ranges, non-smoking, participation in exercise training).RESULTS: Patients in group 1 were less often followed up compared to patients in group 2 and less often achieved any of the secondary prevention targets. Participation in the 6-10 week follow-up was associated with a 3-20% risk reduction in group 1, similar as for group 2 according to interaction analysis. The improvement in outcome in group 1 was mainly mediated by achieving target range low-density lipoprotein cholesterol levels (24-32% risk reduction) and, to a smaller extent, by participation in exercise training (10-23% risk reduction).CONCLUSIONS: Selected secondary preventive measures are associated with prognostic benefit in myocardial infarction patients with non-obstructive coronary arteries, in particular achieving target range low-density lipoprotein cholesterol levels. Our results indicate that these patients should receive similar follow-up as myocardial infarction patients with significant coronary stenoses.
10.	Feichtinger, Michael, et al. (författare) Endometriosis and cumulative live birth rate after fresh and frozen IVF cycles with single embryo transfer in young women : no impact beyond reduced ovarian sensitivity-a case control study 2019 Ingår i: Journal of Assisted Reproduction and Genetics. - : SPRINGER/PLENUM PUBLISHERS. - 1058-0468 .- 1573-7330. ; 36:8, s. 1649-1656 Tidskriftsartikel (refereegranskat)abstract Purpose To investigate the impact of symptomatic and surgically confirmed endometriosis on ovarian sensitivity index (OSI) and cumulative live-birth rates (LBR) using predominantly single embryo transfer (SET). Methods Cross-sectional case-control study in a University-based ART program. Women with symptomatic and surgically confirmed endometriosis (N = 172), who underwent IVF/ICSI at Karolinska University Hospital were compared to controls without clinically suspected endometriosis (N = 2585). Two thousand seven hundred fifty-seven patients underwent 8236 treatment cycles (4598 fresh and 3638 frozen cycles). Primary outcome measures included Ovarian Sensitivity Index (OSI) estimated as collected oocytes/FSH dose and cumulative LBR/oocyte pickup (OPU). Generalized estimated equation (GEE) model accounting for dependencies between consecutive treatments were applied. Secondary outcomes included number of oocytes, pregnancy rate per OPU and per ET, LBR per ET, and miscarriage rate. Results Patients diagnosed with endometriosis had significantly fewer oocytes collected (8.47 vs. 9.54, p = 0.015) and lower OSI (p = 0.011) than controls. There were no differences in cycle cancelations (p = 0.59) or miscarriages (p = 0.95) between the two groups. Cumulative LBR/OPU did not differ between women with endometriosis and controls (35.6% vs. 34.7%, respectively, p = 0.83). In both groups, more than 60% of women had consecutive FETs after fresh ETs (p = 0.49) with SET in > 70% of cases. The results were similar whether ovarian endometrioma was present or not. Conclusions Our data support that a diagnosis of endometriosis, with or without present endometrioma, does not negatively affect ART cumulative results. The impact of endometriosis was discernible on OSI but not on clinical relevant outcomes including pregnancy and LBR.
11.	Figtree, Gemma A., et al. (författare) Mortality and Cardiovascular Outcomes in Patients Presenting With Non-ST Elevation Myocardial Infarction Despite No Standard Modifiable Risk Factors : Results From the SWEDEHEART Registry 2022 Ingår i: Journal of the American Heart Association. - : John Wiley & Sons. - 2047-9980. ; 11:15 Tidskriftsartikel (refereegranskat)abstract Background A significant proportion of patients with ST-segment-elevation myocardial infarction (MI) have no standard modifiable cardiovascular risk factors (SMuRFs) and have unexpected worse 30-day outcomes compared with those with SMuRFs. The aim of this article is to examine outcomes of patients with non-ST-segment-elevation MI in the absence of SMuRFs.Methods and Results Presenting features, management, and outcomes of patients with non-ST-segment-elevation MI without SmuRFs (hypertension, diabetes, hypercholesterolemia, smoking) were compared with those with SmuRFs in the Swedish MI registry SWEDEHEART (Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies; 2005-2018). Cox proportional hazard models were used. Out of 99 718 patients with non-ST-segment-elevation MI, 11 131 (11.2%) had no SMuRFs. Patients without SMuRFs had higher all-cause and cardiovascular mortality at 30 days (hazard ratio [HR], 1.20 [95% CI, 1.10-1.30], P<0.0001; and HR, 1.25 [95% CI, 1.13-1.38]), a difference that remained after adjustment for age and sex. SMuRF-less patients were less likely to receive secondary prevention statins (76% versus 82%); angiotensin-converting enzyme inhibitors/angiotensin receptor blockade (54% versus 72%); or beta-blockers (81% versus 87%, P for all <0.0001), with lowest rates observed in women without SMuRFs. In patients who survived to 30 days, rates of all-cause and cardiovascular death were lower in patients without SMuRFs compared with those with risk factors, over 12 years.Conclusions One in 10 patients presenting with non-ST-segment-elevation MI present without traditional risk factors. The excess 30-day mortality rate in this group emphasizes the need for both improved population-based strategies for prevention of MI, as well as the need for equitable evidence-based treatment at the time of an MI.
12.	Figtree, Gemma A., et al. (författare) Mortality in STEMI patients without standard modifiable risk factors : a sex-disaggregated analysis of SWEDEHEART registry data 2021 Ingår i: The Lancet. - : ELSEVIER SCIENCE INC. - 0140-6736 .- 1474-547X. ; 397:10279, s. 1085-1094 Tidskriftsartikel (refereegranskat)abstract Background In cardiovascular disease, prevention strategies targeting standard modifiable cardiovascular risk factors (SMuRFs; hypertension, diabetes, hypercholesterolaemia, and smoking) are crucial; however, myocardial infarction in the absence of SMuRFs is not infrequent. The outcomes of individuals without SMuRFs are not well known. Methods We retrospectively analysed adult patients with first-presentation ST-elevation myocardial infarction (STEMI) using data from the Swedish myocardial infarction registry SWEDEHEART. Clinical characteristics and outcomes of adult patients (age >= 18 years) with and without SMuRFs were examined overall and by sex. Patients with a known history of coronary artery disease were excluded. The primary outcome was all-cause mortality at 30 days after STEMI presentation. Secondary outcomes included cardiovascular mortality, heart failure, and myocardial infarction at 30 days. Endpoints were also examined up to discharge, and to the end of a 12-year follow-up. Multivariable logistic regression models were used to compare in-hospital mortality, and Cox-proportional hazard models and Kaplan-Meier analysis for long-term outcomes. Findings Between Jan 1, 2005, and May 25, 2018, 9228 (14.9%) of 62 048 patients with STEMI had no SMuRFs reaching diagnostic thresholds. Median age was similar between patients with SMuRFs and patients without SMuRFs (68 years [IQR 59-78]) vs 69 years [60-78], p<0.0001). SMuRF-less patients had a similar rate of percutaneous coronary intervention to those with at least one modifiable risk factor, but were significantly less likely to receive statins, angiotensin converting enzyme inhibitors (ACEIs) or angiotensin receptor blockade (ARB), or beta-blockers at discharge. By 30 days after presentation, all-cause mortality was significantly higher in SMuRF-less patients (hazard ratio 1.47 [95% CI 1.37-1.57], p<0.0001). SMuRF-less women had the highest 30-day mortality (381 [17.6%] of 2164), followed by women with SMuRFs (2032 [11.1%] of 18 220), SMuRF-less men (660 [9.3%] of 7064), and men with SMuRFs (2117 [6.1%] of 34 600). The increased risk of 30-day all-cause mortality in SMuRF-less patients remained significant after adjusting for age, sex, left ventricular ejection fraction, creatinine, and blood pressure, but was attenuated on inclusion of pharmacotherapy prescription (ACEI or ARB, beta-blocker, or statin) at discharge. Additionally, SMuRF-less patients had a significantly higher rate of in-hospital all-cause mortality than patients with one or more SMuRF (883 [9.6%] vs 3411 [6.5%], p<0.0001). Myocardial infarction and heart failure at 30 days were lower in SMuRF-less patients. All-cause mortality remained increased in the SMuRF-less group for more than 8 years in men and up to the 12-year endpoint in women. Interpretation Individuals who present with STEMI in the absence of SMuRFs have a significantly increased risk of all-cause mortality, compared with those with at least one SMuRF, which was particularly evident in women. The increased early mortality rates are attenuated after adjustment for use of guideline-indicated treatments, highlighting the need for evidence-based pharmacotherapy during the immediate post-infarct period irrespective of perceived low risk.

13.	Gard, Anton, et al. (författare) Interphysician agreement on subclassification of myocardial infarction. 2018 Ingår i: Heart. - : BMJ. - 1355-6037 .- 1468-201X. ; 104:15, s. 1284-1291 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: The universal definition of myocardial infarction (MI) differentiates MI due to oxygen supply/demand mismatch (type 2) from MI due to plaque rupture (type 1) as well as from myocardial injuries of non-ischaemic or multifactorial nature. The purpose of this study was to investigate how often physicians agree in this classification and what factors lead to agreement or disagreement.METHODS: A total of 1328 patients diagnosed with MI at eight different Swedish hospitals 2011 were included. All patients were retrospectively reclassified into different MI or myocardial injury subtypes by two independent specially trained physicians, strictly adhering to the third universal definition of MI.RESULTS: Overall, there was a moderate interobserver agreement with a kappa coefficient (κ) of 0.55 in this classification. There was substantial agreement when distinguishing type 1 MI (κ: 0.61), compared with moderate agreement when distinguishing type 2 MI (κ: 0.54). In multivariate logistic regression analyses, ST elevation MI (P<0.001), performed coronary angiography (P<0.001) and larger changes in troponin levels (P=0.023) independently made the physicians agree significantly more often, while they disagreed more often with symptoms of dyspnoea (P<0.001), higher systolic blood pressure (P=0.001) and higher C reactive protein levels on admission (P=0.016).CONCLUSION: Distinguishing MI types is challenging also for trained adjudicators. Although strictly adhering to the third universal definition of MI, differentiation between type 1 MI, type 2 MI and myocardial injury only gave a moderate rate of interobserver agreement. More precise and clinically applicable criteria for the current classification, particularly for type 2 MI diagnosis, are urgently needed.
14.	Gard, Anton, 1985-, et al. (författare) Treatment and Prognosis of Myocardial Infarction Outside Cardiology Departments. 2020 Ingår i: Journal of Clinical Medicine. - BASEL SWITZERLAND : MDPI AG. - 2077-0383. ; 10:1 Tidskriftsartikel (refereegranskat)abstract AIM: Our aim was to investigate the characteristics, treatment and prognosis of patients with myocardial infarction (MI) treated outside a cardiology department (CD), compared with MI patients treated at a CD.METHODS: A cohort of 1310 patients diagnosed with MI at eight Swedish hospitals in 2011 were included in this observational study. Patients were followed regarding all-cause mortality until 2018.RESULTS: A total of 235 patients, exclusively treated outside CDs, were identified. These patients had more non-cardiac comorbidities, were older (mean age 83.7 vs. 73.1 years) and had less often type 1 MIs (33.2% vs. 74.2%), in comparison with the CD patients. Advanced age and an absence of chest pain were the strongest predictors of non-CD care. Only 3.8% of non-CD patients were investigated with coronary angiography and they were also prescribed secondary preventive pharmacological treatments to a lesser degree, with only 32.3% having statin therapy at discharge. The all-cause mortality was higher in non-CD patients, also after adjustment for baseline parameters, both at 30 days (hazard ratio (HR) 2.28; 95% confidence interval (CI) 1.62-3.22), one year (HR 1.82; 95% CI 1.39-2.36) and five years (HR 1.62; 95% CI 1.32-1.98).CONCLUSIONS: MI treatment outside CDs is associated with an adverse short- and long-term prognosis. An improved use of percutaneous coronary intervention (PCI) and secondary preventive pharmacological treatment might improve the long-term prognosis in these patients.
15.	Hallberg, Ida, et al. (författare) Associations between lifestyle factors and levels of per- and polyfluoroalkyl substances (PFASs), phthalates and parabens in follicular fluid in women undergoing fertility treatment 2023 Ingår i: Journal of Exposure Science and Environmental Epidemiology. - : Springer Nature. - 1559-0631 .- 1559-064X. ; 33, s. 699-709 Tidskriftsartikel (refereegranskat)abstract Background: Concerns have been raised whether exposure to endocrine-disrupting chemicals (EDCs) can alter reproductive functions and play a role in the aetiology of infertility in women. With increasing evidence of adverse effects, information on factors associated with exposure is necessary to form firm recommendations aiming at reducing exposure.Objective: Our aim was to identify associations between lifestyle factors including the home environment, use of personal care products (PCP), and dietary habits and concentrations of EDCs in ovarian follicular fluid.Methods: April-June 2016, 185 women undergoing ovum pick-up for in vitro fertilisation in Sweden were recruited. Correlation analyses were performed between self-reported lifestyle factors and concentration of EDCs analysed in follicular fluid. Habits related to cleaning, PCPs, and diet were assessed together with concentration of six per- and polyfluoroalkyl substances (PFASs) [PFHxS, PFOA, PFOS, PFNA, PFDA and PFUnDA], methyl paraben and eight phthalate metabolites [MECPP, MEHPP, MEOHP, MEHP, cxMinCH, cxMiNP, ohMiNP, MEP, MOHiBP]. Spearman's partial correlations were adjusted for age, parity and BMI.Results: Significant associations were discovered between multiple lifestyle factors and concentrations of EDCs in ovarian follicular fluid. After correcting p values for multiple testing, frequent use of perfume was associated with MEP (correlation rho = 0.41 (confidence interval 0.21-0.47), p < 0.001); hens' egg consumption was positively associated with PFOS (rho = 0.30 (0.15-0.43), p = 0.007) and PFUnDA (rho = 0.27 (0.12-0.40), p = 0.036). White fish consumption was positively associated with PFUnDA (rho = 0.34 (0.20-0.47), p < 0.001) and PFDA (rho = 0.27 (0.13-0.41), p = 0.028). More correlations were discovered when considering the raw uncorrected p values. Altogether, our results suggest that multiple lifestyle variables affect chemical contamination of follicular fluid.Impact statement: This study shows how lifestyle factors correlate with the level of contamination in the ovary by both persistent and semi-persistent chemicals in women of reproductive age. Subsequently, these data can be used to form recommendations regarding lifestyle to mitigate possible negative health outcomes and fertility problems associated with chemical exposure, and to inform chemical policy decision making. Our study can also help form the basis for the design of larger observational and intervention studies to examine possible effects of lifestyle changes on exposure levels, and to unravel the complex interactions between biological factors, lifestyle and chemical exposures in more detail.

17.	Hammar, Per, et al. (författare) Unrecognized myocardial infarctions assessed by cardiovascular magnetic resonance are associated with the severity of the stenosis in the supplying coronary artery 2015 Ingår i: Journal of Cardiovascular Magnetic Resonance. - : BioMed Central. - 1097-6647 .- 1532-429X. ; 17 Tidskriftsartikel (refereegranskat)abstract Background: A previous study has shown an increased prevalence of late gadolinium enhancement cardiovascular magnetic resonance (LGE CMR) detected unrecognized myocardial infarction (UMI) with increasing extent and severity of coronary artery disease. However, the coronary artery disease was evaluated on a patient level assuming normal coronary anatomy. Therefore, the aims of the present study were to investigate the prevalence of UMI identified by LGE CMR imaging in patients with stable angina pectoris and no known previous myocardial infarction; and to investigate whether presence of UMI is associated with stenotic lesions in the coronary artery supplying the segment of the myocardium in which the UMI is located, using coronary angiography to determine the individual coronary anatomy in each patient.Methods: In this prospective multicenter study, we included patients with stable angina pectoris and without prior myocardial infarction, scheduled for coronary angiography. A LGE CMR examination was performed prior to the coronary angiography. The study cohort consisted of 235 patients (80 women, 155 men) with a mean age of 64.8 years.Results: UMIs were found in 25 % of patients. There was a strong association between stenotic lesions (>= 70 % stenosis) in a coronary artery and the presence of an UMI in the myocardial segments supplied by the stenotic artery; it was significantly more likely to have an UMI downstream a stenosis >= 70 % as compared to <70 % (OR 5.1, CI 3.1-8.3, p < 0.0001). 56 % of the UMIs were located in the inferior and infero-lateral myocardial segments, despite predominance for stenotic lesions in the left anterior descending artery.Conclusion: UMI is common in patients with stable angina and the results indicate that the majority of the UMIs are of ischemic origin due to severe coronary atherosclerosis. In contrast to what is seen in recognized myocardial infarctions, UMIs are predominately located in the inferior and infero-lateral myocardial segments.

(författare) Body Mass Index and Association With Cardiovascular Outcomes in Patients With Stable Coronary Heart Disease - A STABILITY Substudy 2022 Ingår i: Journal of the American Heart Association. - : Ovid Technologies (Wolters Kluwer Health). - 2047-9980. ; 11:3 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: The obesity paradox states that patients with higher body mass index (BMI) and cardiovascular disease may experience better prognosis. However, this is less clear in patients with coronary heart disease. METHODS AND RESULTS: The prospective STABILITY (Stabilization of Atherosclerotic Plaque by Initiation of Darapladib Therapy) trial included 15 828 patients with stable coronary heart disease with 3 to 5 years' follow-up on optimal secondary preventive treatment. BMI was measured at baseline (n=15 785). Associations between BMI and cardiovascular outcomes were evaluated by Cox regression analyses with multivariable adjustments. Mean age was 64 +/- 9 years and 19% women. Most risk markers (diabetes, hypertension, inflammatory biomarkers, triglycerides) showed a graded association with higher BMI. The frequency of smoking, levels of high-density lipoprotein, growth differentiation factor 15, and NT-proBNP (N-terminal pro-Btype natriuretic peptide) were higher at lower BMI. Low BMI (<20 kg/m(2); n=244 [1.5%]) was associated with doubled risk of total death (hazard ratio [HR], 2.27; 95% CI, 1.60-3.22), cardiovascular death (HR, 2.26; 95% CI, 1.46-3.49), and heart failure (HR, 2.51; 95% CI, 1.35-4.68) compared with BMI of 25 to <30 kg/m(2) (n=6752 [42.8%]) as reference. Similarly, high BMI of >= 35 kg/m(2) (n=1768 [11.2%]) was associated with increased risk of the same outcomes. A BMI between 20 and <25 kg/m(2) was associated with increased risk of cardiovascular death (HR, 1.26; 95% CI, 1.03-1.54) and total death (HR, 1.21; 95% CI, 1.03-1.42). CONCLUSIONS: Patients with stable coronary heart disease showed a graded increase in cardiometabolic and inflammatory risk factors with increasing BMI category >25 kg/m(2). All-cause and cardiovascular mortality were lowest at BMI of 25 to 35 kg/m(2). Underweight with BMI of <20 kg/m(2) and very high BMI of >= 35 kg/m(2) were strong risk markers for poor prognosis.

(författare) Antral follicle counts are strongly associated with live-birth rates after assisted reproduction, with superior treatment outcome in women with polycystic ovaries 2011 Ingår i: Fertility and Sterility. - : Elsevier BV. - 0015-0282 .- 1556-5653. ; 96:3, s. 594-599 Tidskriftsartikel (refereegranskat)abstract Objective: To evaluate the association of antral follicle count (AFC) with in vitro fertilization/intracytoplasmic sperm injection (IVF-ICSI) outcome in a large unselected cohort of patients covering the entire range of AFC. Design: Prospective observational study. Setting: University-affiliated private infertility center. Patient(s): 2,092 women undergoing 4,308 IVF-ICSI cycles. Intervention(s): AFC analyzed for associations with treatment outcome and statistically adjusted for repeated treatments and age. Main Outcome Measure(s): Pregnancy rate, live-birth rate, and stimulation outcome parameters. Result(s): The AFC was log-normally distributed. Pregnancy rates and live-birth rates were positively associated with AFC in a log-linear way, leveling out above AFC similar to 30. Treatment outcome was superior among women with polycystic ovaries, independent from ovulatory status. The findings were significant also after adjustment for age and number of oocytes retrieved. Conclusion(s): Pregnancy and live-birth rates are log-linearly related to AFC. Polycystic ovaries, most often excluded from studies on ovarian reserve, fit as one extreme in the spectrum of AFC; a low count constitutes the other extreme, with the lowest ovarian reserve and poor treatment outcome. The findings remained statistically significant also after adjustment for the number of oocytes retrieved, suggesting this measure of ovarian reserve comprises information on oocyte quality and not only quantity.

Design: Retrospective cross-sectional study. Setting: University-affiliated private center. Patient(s): The entire unselected cohort of 7,520 IVF/intracytoplasmic sperm injection treatments (oocyte pick-ups [OPUs]) during an 8-year period (long GnRH agonist-recombinant FSH protocol). Intervention(s): None. Main Outcome Measure(s): The distribution of the OSI (oocytes recovered x 1,000/total dose of FSH), the cutoff levels for poor and high response, set at +/- 1 SD, and the relationship between OSI and treatment outcome. Result(s): OSI showed a log-normal distribution with cutoff levels for poor and high response at 1.697/IU and 10.07/IU, respectively. A nomogram is presented. Live-birth rates per OPU were 10.5 +/- 0.1%, 26.9 +/- 0.6%, and 36.0 +/- 1.4% for poor, normal, and high response treatments, respectively. The predictive power (C-statistic) for OSI to predict live birth was superior to that of oocyte yield. Conclusion(s): The OSI improves the definition of ovarian response patterns because it takes into account the degree of stimulation. The nomogram presents evidence-based cutoff levels for poor, normal, and high response and could be used for unifying study designs involving ovarian response patterns.

(författare) The facial nerve palsy and cortisone evaluation (FACE) study in children : protocol for a randomized, placebo-controlled, multicenter trial, in a Borrelia burgdorferi endemic area. 2021 Ingår i: BMC Pediatrics. - : BioMed Central (BMC). - 1471-2431. ; 21:1 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Children with acute peripheral facial nerve palsy cannot yet be recommended corticosteroid treatment based on evidence. Adults with idiopathic facial nerve palsy are treated with corticosteroids, according to guidelines resulting from a meta-analysis comprising two major randomized placebo-controlled trials. Corresponding trials in children are lacking. Furthermore, acute facial nerve palsy in childhood is frequently associated with Lyme neuroborreliosis, caused by the spirochete Borrelia burgdorferi. The efficacy and safety of corticosteroid treatment of acute facial nerve palsy associated with Lyme neuroborreliosis, has not yet been determined in prospective trials in children, nor in adults.METHOD: This randomized double-blind, placebo-controlled study will include a total of 500 Swedish children aged 1-17 years, presenting with acute facial nerve palsy of either idiopathic etiology or associated with Lyme neuroborreliosis. Inclusion is ongoing at 12 pediatric departments, all situated in Borrelia burgdorferi endemic areas. Participants are randomized into active treatment with prednisolone 1 mg/kg/day (maximum 50 mg/day) or placebo for oral intake once daily during 10 days without taper. Cases associated with Lyme neuroborreliosis are treated with antibiotics in addition to the study treatment. The House-Brackmann grading scale and the Sunnybrook facial grading system are used for physician-assessed evaluation of facial impairment at baseline, and at the 1- and 12-month follow-ups. Primary outcome is complete recovery, measured by House-Brackmann grading scale, at the 12-month follow-up. Child/parent-assessed questionnaires are used for evaluation of disease-specific quality of life and facial disability and its correlation to physician-assessed facial impairment will be evaluated. Furthermore, the study will evaluate factors of importance for predicting recovery, as well as the safety profile for short-term prednisolone treatment in children with acute facial nerve palsy.DISCUSSION: This article presents the rationale, design and content of a protocol for a study that will determine the efficacy of corticosteroid treatment in children with acute facial nerve palsy of idiopathic etiology, or associated with Lyme neuroborreliosis. Future results will attribute to evidence-based treatment guidelines applicable also in Borrelia burgdorferi endemic areas.TRIAL REGISTRATION: The study protocol was approved by the Swedish Medical Product Agency (EudraCT nr 2017-004187-35) and published at ClinicalTrials.gov ( NCT03781700 , initial release 12/14/2018).

(författare) Does ovarian stimulation regimen affect IVF outcome? : a two-centre, real-world retrospective study using predominantly cleavage-stage, single embryo transfer 2018 Ingår i: Reproductive BioMedicine Online. - : ELSEVIER SCI LTD. - 1472-6483 .- 1472-6491. ; 36:1, s. 59-66 Tidskriftsartikel (refereegranskat)abstract In this study, ovarian stimulation using highly purified human menopausal gonadotrophin (HP-HMG) and recombinant FSH (rFSH) for IVF were compared in two large assisted reproduction technique centres in Sweden. A total of 5902 women underwent 9631 oocyte retrievals leading to 8818 embryo transfers (7720 on day 2): single embryo transfers (74.2%); birth rate per embryo transfer (27.7%); multiple birth rate (5.0%); incidence of severe ovarian hyperstimulation syndrome (0.71%). Compared with ovarian stimulation with rFSH, women who received HP-HMG were older, had higher dosages of gonadotrophins administered, fewer oocytes retrieved and more embryos transferred. After multivariate analysis controlling for age and generalized estimating equation model, no differences were found in delivery outcomes per embryo transfers between HP-HMG and rFSH, independent of gonadotrophin releasing hormone analogue (GnRH) used. Logit curves for live birth rate suggested differences for various subgroups, most prominently for women with high oocyte yield or when high total doses were used. Differences were not significant, perhaps owing to skewed distributions of the FSH compounds versus age and other covariates. These 'real-life patients' had no differences in live birth rate between HP-HMG and rFSH overall or in subgroups of age, embryo score, ovarian sensitivity or use of GnRH analogue regimen.

Medication reviews improve medication use, but evidence of the possible benefit of inpatient medication review for hard clinical outcomes after discharge is scarce.Objective: To study the effects of hospital-based comprehensive medication reviews (CMRs), including postdischarge follow-up of older patients’ use of health care resources, compared with only hospital-based reviews and usual care.Design, Setting, and Participants: The Medication Reviews Bridging Healthcare trial is a cluster randomized crossover trial that was conducted in 8 wards with multiprofessional teams at 4 hospitals in Sweden from February 6, 2017, to October 19, 2018, with 12 months of follow-up completed December 6, 2019. The study was prespecified in the trial protocol. Outcome assessors were blinded to treatment allocation. In total, 2644 patients aged 65 years or older who had been admitted to 1 of the study wards for at least 1 day were included. Data from the modified intention-to-treat population were analyzed from December 10, 2019, to September 9, 2020.Interventions: Each ward participated in the trial for 6 consecutive 8-week periods. The wards were randomized to provide 1 of 3 treatments during each period: CMR, CMR plus postdischarge follow-up, and usual care without a clinical pharmacist.Main Outcomes and Measures: The primary outcome measure was the incidence of unplanned hospital visits (admissions plus emergency department visits) within 12 months. Secondary outcomes included medication-related admissions, visits with primary care clinicians, time to first unplanned hospital visit, mortality, and costs of hospital-based care.Results: Of the 2644 participants, 7 withdrew after inclusion, leaving 2637 for analysis (1357 female [51.5%]; median age, 81 [interquartile range, 74-87] years; median number of medications, 9 [interquartile range, 5-13]). In the modified intention-to-treat analysis, 922 patients received CMR, 823 received CMR plus postdischarge follow-up, and 892 received usual care. The crude incidence rate of unplanned hospital visits was 1.77 per patient-year in the total study population. The primary outcome did not differ between the intervention groups and usual care (adjusted rate ratio, 1.04 [95% CI, 0.89-1.22] for CMR and 1.15 [95% CI, 0.98-1.34] for CMR plus postdischarge follow-up). However, CMR plus postdischarge follow-up was associated with an increased incidence of emergency department visits within 12 months (adjusted rate ratio, 1.29; 95% CI, 1.05-1.59) compared with usual care. There were no differences between treatment groups regarding other secondary outcomes.Conclusions and Relevance: In this study of older hospitalized patients, CMR plus postdischarge follow-up did not decrease the incidence of unplanned hospital visits. The findings do not support the performance of hospital-based CMRs as conducted in this trial. Alternative forms of medication reviews that aim to improve older patients’ health outcomes should be considered and subjected to randomized clinical trials.

(författare) Risk factors for and preventability of drug-related hospital revisits in older patients: A post-hoc analysis of a randomized clinical trial 2023 Ingår i: British Journal of Clinical Pharmacology. - : WILEY. - 0306-5251 .- 1365-2125. ; 89:5, s. 1575-1587 Tidskriftsartikel (refereegranskat)abstract AimThe aims of this study were (1) to identify older patients risk factors for drug-related readmissions and (2) to assess the preventability of older patients drug-related revisits. MethodsPost hoc analysis of a randomized clinical trial with patients aged >= 65 years at eight wards within four hospitals in Sweden. (1) The primary outcome was risk factors for drug-related readmission within 12 months post-discharge. A Cox proportional hazards model was made with sociodemographic and clinical baseline characteristics. (2) Four hundred trial participants were randomly selected and their revisits (admissions and emergency department visits) were assessed to identify potentially preventable drug-related revisits, related diseases and causes. Results(1) Among 2637 patients (median age 81 years), 582 (22%) experienced a drug-related readmission within 12 months. Sixteen risk factors (hazard ratio >1, P < 0.05) related to age, previous hospital visits, medication use, multimorbidity and cardiovascular, liver, lung and peptic ulcer disease were identified. (2) The 400 patients experienced a total of 522 hospital revisits, of which 85 (16%) were potentially preventable drug-related revisits. The two most prevalent related diseases were heart failure (n = 24, 28%) and chronic obstructive pulmonary disease (n = 13, 15%). The two most prevalent causes were inadequate treatment (n = 23, 27%) and insufficient or no follow-up (n = 22, 26%). Conclusion(1) Risk factors for drug-related readmissions in older hospitalized patients were age, previous hospital visits, medication use and multiple diseases. (2) Potentially preventable drug-related hospital revisits are common and might be prevented through adequate pharmacotherapy and continuity of care in older patients with cardiovascular or lung disease.

Here, we describe temporal trends in risk factors, lifestyle and preventive medication for patients after myocardial infarction (MI) registered in the quality registry Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapies (SWEDEHEART).Design: A registry-based cohort study.Setting: All coronary care units and cardiac rehabilitation (CR) centres in Sweden.Participants: Patients attending a CR visit at 1-year post-MI 2006-2019 were included (n=81 363, 18-74 years, 74.7% men).Outcome measures: Outcome measures at 1-year follow-up included blood pressure (BP) <140/90 mm Hg, low-density lipoprotein-cholesterol (LDL-C)<1.8 mmol/L, persistent smoking, overweight/obesity, central obesity, diabetes prevalence, inadequate physical activity, and prescription of secondary preventive medication. Descriptive statistics and testing for trends were applied.Results: The proportion of patients attaining the targets for BP<140/90 mmHg increased from 65.2% (2006) to 86.0% (2019), and LDL-C<1.8 mmol/L from 29.8% (2006) to 66.9% (2019, p<0.0001 both). While smoking at the time of MI decreased (32.0% to 26.5%, p<0.0001), persistent smoking at 1 year was unchanged (42.8% to 43.2%, p=0.672) as was the prevalence of overweight/obesity (71.9% to 72.9%, p=0.559). Central obesity (50.5% to 57.0%), diabetes (18.2% to 27.2%) and patients reporting inadequate levels of physical activity (57.0% to 61.5%) increased (p<0.0001 for all). From 2007, >90.0% of patients were prescribed statins and approximately 98% antiplatelet and/or anticoagulant therapy. Angiotensin-converting enzyme inhibitor/angiotensin receptor blocker prescription increased from 68.7% (2006) to 80.2% (2019, p<0.0001).Conclusions: While little change was observed for persistent smoking and overweight/obesity, large improvements were observed for LDL-C and BP target achievements and prescription of preventive medication for Swedish patients after MI 2006-2019. Compared with published results from patients with coronary artery disease in Europe during the same period, these improvements were considerably larger. Continuous auditing and open comparisons of CR outcomes might possibly explain some of the observed improvements and differences.

27.	Lind, Tekla, et al. (författare) Reduced live-birth rates after IVF/ICSI in women with previous unilateral oophorectomy : results of a multicentre cohort study 2018 Ingår i: Human Reproduction. - : Oxford University Press. - 0268-1161 .- 1460-2350. ; 33:2, s. 238-247 Tidskriftsartikel (refereegranskat)abstract Is there a reduced live-birth rate (LBR) after IVF/ICSI treatment in women with a previous unilateral oophorectomy (UO)? A significantly reduced LBR after IVF/ICSI was found in women with previous UO when compared with women with intact ovaries in this large multicentre cohort, both crudely and after adjustment for age, BMI, fertility centre and calendar period and regardless of whether the analysis was based on transfer of embryos in the fresh cycle only or on cumulative results including transfers using frozen-thawed embryos. Similar pregnancy rates after IVF/ICSI have been previously reported in case-control studies and small cohort studies of women with previous UO versus women without ovarian surgery. In all previous studies multiple embryos were transferred. No study has previously evaluated LBR in a large cohort of women with a history of UO. This research was a multicentre cohort study, including five reproductive medicine centres in Sweden: Carl von Linn, Clinic (A), Karolinska University Hospital (B), Uppsala University Hospital (C), Linkoping University Hospital (D) and A-rebro University Hospital (E). The women underwent IVF/ICSI between January 1999 and November 2015. Single embryo transfer (SET) was performed in approximately 70% of all treatments, without any significant difference between UO exposed women versus controls (68% versus 71%), respectively (P = 0.32), and a maximum of two embryos were transferred in the remaining cases. The dataset included all consecutive treatments and fresh and frozen-thawed cycles. The exposed cohort included 154 women with UO who underwent 301 IVF/ICSI cycles and the unexposed control cohort consisted of 22 693 women who underwent 41 545 IVF/ICSI cycles. Overall, at the five centres (A-E), the exposed cohort underwent 151, 34, 35, 41 and 40 treatments, respectively, and they were compared with controls of the same centre (18 484, 8371, 5575, 4670 and 4445, respectively). The primary outcome was LBR, which was analysed per started cycle, per ovum pick-up (OPU) and per embryo transfer (ET). Secondary outcomes included the numbers of oocytes retrieved and supernumerary embryos obtained, the Ovarian Sensitivity Index (OSI), embryo quality scores and cumulative pregnancy rates. We used a Generalized Estimating Equation (GEE) model for statistical analysis in order to account for repeated treatments. MAIN RESULTS AND THE ROLE OF CHANCE: The exposed (UO) and control women's groups were comparable with regard to age and performance of IVF or ICSI. Significant differences in LBR, both crude and age-adjusted, were observed between the UO and control groups: LBR per started cycle (18.6% versus 25.4%, P = 0.007 and P = 0.014, respectively), LBR/OPU (20.3% versus 27.1%, P = 0.012 and P = 0.015, respectively) and LBR/ET (23.0% versus 29.7%, P = 0.022 and P = 0.025, respectively). The differences in LBR remained significant after inclusion of both fresh and frozen-thawed transfers (both crude and age-adjusted data): LBR/OPU (26.1% versus 34.4%, P = 0.005 and P = 0.006, respectively) and LBR/ET (28.3% versus 37.1%, P = 0.006 and P = 0.006, respectively). The crude cancellation rate was significantly higher among women with a history of UO than in controls (18.9% versus 14.5%, P = 0.034 and age-adjusted, P = 0.178). In a multivariate GEE model, the cumulative odds ratios for LBR (fresh and frozen-thawed)/OPU (OR 0.70, 95% CI 0.52-0.94, P = 0.016) and LBR (fresh and frozen-thawed)/ET (OR 0.68, 95% CI 0.51-0.92, P = 0.012) were approximately 30% lower in the group of women with UO when adjusted for age, BMI, reproductive centre, calendar period and number of embryos transferred when appropriate. The OSI was significantly lower in women with a history of UO than in controls (3.6 versus 6.0) and the difference was significant for both crude and age-adjusted data (P =< 0.001 for both). Significantly fewer oocytes were retrieved in treatments of women with UO than in controls (7.2 versus 9.9, P = < 0.001, respectively). LIMITATIONS, REASONS FOR CAUTION: Due to the nature of the topic, this is a retrospective analysis, with all its inherent limitations. Furthermore, the cause for UO was not possible to obtain in all cases. A diagnosis of endometriosis was also more common in the UO group, i. e. a selection bias in terms of poorer patient characteristics in the UO group cannot be completely ruled out. However, adjustment for all known confounders did not affect the general results. WIDER IMPLICATIONS OF THE FINDINGS: To date, this is the largest cohort investigated and the first study indicating an association of achieving reduced live birth after IVF/ICSI in women with previous UO. These findings are novel and contradict the earlier notion that IVF/ICSI treatment is not affected, or is only marginally affected by previous UO.

Clinical trials of secondary prevention treatment in MINOCA patients are lacking. Therefore, the aim of this study was to examine the associations between treatment with statins, renin-angiotensin system blockers, β-blockers, dual antiplatelet therapy, and long-term cardiovascular events.METHODS: This is an observational study of MINOCA patients recorded in the SWEDEHEART registry (the Swedish Web-system for Enhancement and Development of Evidence-based care in Heart disease Evaluated According to Recommended Therapy) between July 2003 and June 2013 and followed until December 2013 for outcome events in the Swedish Cause of Death Register and National Patient Register. Of 199 162 myocardial infarction admissions, 9466 consecutive unique patients with MINOCA were identified. Among those, the 9136 patients surviving the first 30 days after discharge constituted the study population. Mean age was 65.3 years, and 61% were women. No patient was lost to follow-up. A stratified propensity score analysis was performed to match treated and untreated groups. The association between treatment and outcome was estimated by comparing between treated and untreated groups by using Cox proportional hazards models. The exposures were treatment at discharge with statins, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, β-blockers, and dual antiplatelet therapy. The primary end point was major adverse cardiac events defined as all-cause mortality, hospitalization for myocardial infarction, ischemic stroke, and heart failure.RESULTS: At discharge, 84.5%, 64.1%, 83.4%, and 66.4% of the patients were on statins, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, β-blockers, and dual antiplatelet therapy, respectively. During the follow-up of a mean of 4.1 years, 2183 (23.9%) patients experienced a major adverse cardiac event. The hazard ratios (95% confidence intervals) for major adverse cardiac events were 0.77 (0.68-0.87), 0.82 (0.73-0.93), and 0.86 (0.74-1.01) in patients on statins, angiotensin-converting enzyme inhibitors/angiotensin receptor blockers, and β-blockers, respectively. For patients on dual antiplatelet therapy followed for 1 year, the hazard ratio was 0.90 (0.74-1.08).CONCLUSIONS: The results indicate long-term beneficial effects of treatment with statins and angiotensin-converting enzyme inhibitors/angiotensin receptor blockers on outcome in patients with MINOCA, a trend toward a positive effect of β-blocker treatment, and a neutral effect of dual antiplatelet therapy. Properly powered randomized clinical trials to confirm these results are warranted.

Study Design: Data from a prospective, randomized, double-blind, placebo-controlled, multicenter study. Methods: There were 829 patients with Bell's palsy randomized in a factorial fashion to treatment with prednisolone or no prednisolone. Facial function was assessed with the Sunnybrook grading scale. Univariate and multivariate logistic regression analyses at different time points were used to identify factors predicting nonrecovery, defined as Sunnybrook < 70 at 12 months. Variables studied were age, gender, time to inclusion, prednisolone treatment, side of palsy, pain at inclusion, and Sunnybrook scores. Factors of predictable significance were used to construct prognostic models at baseline, days 11 to 17, and at 1 month. Receiver operating characteristics curves were created to test the predictive capacity of the models. Results: At baseline, treatment with prednisolone or no prednisolone (P = .0005), age (P = .04) and the Sunnybrook score (P = .0002) were significant factors for predicting nonrecovery. The receiver operating characteristics area under the curve at baseline for these three variables was 0.74 (sensitivity 0.83, specificity 0.57). At days 11 to 17 and at 1 month, the Sunnybrook score was the only significant predictive variable. The respective areas under the curves for the Sunnybrook score at these time points were 0.83 (sensitivity 0.81, specificity 0.75) and 0.94 (sensitivity 0.91, specificity 0.85). Conclusions: Sunnybrook grading at 1 month most accurately predicts nonrecovery at 12 months in Bell's palsy.

(författare) Continuous chest compressions are associated with higher peak inspiratory pressures when compared to 30:2 in an experimental cardiac arrest model 2023 Ingår i: Intensive Care Medicine Experimental. - : Springer. - 2197-425X. ; 11:1 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Ventilation during cardiopulmonary resuscitation (CPR) has long been a part of the standard treatment during cardiac arrests. Ventilation is usually given either during continuous chest compressions (CCC) or during a short pause after every 30 chest compressions (30:2). There is limited knowledge of how ventilation is delivered if it effects the hemodynamics and if it plays a role in the occurrence of lung injuries. The aim of this study was to compare ventilation parameters, hemodynamics, blood gases and lung injuries during experimental CPR given with CCC and 30:2 in a porcine model.METHODS: Sixteen pigs weighing approximately 33 kg were randomized to either receive CPR with CCC or 30:2. Ventricular fibrillation was induced by passing an electrical current through the heart. CPR was started after 3 min and given for 20 min. Chest compressions were provided mechanically with a chest compression device and ventilations were delivered manually with a self-inflating bag and 12 l/min of oxygen. During the experiment, ventilation parameters and hemodynamics were sampled continuously, and arterial blood gases were taken every five minutes. After euthanasia and cessation of CPR, the lungs and heart were removed in block and visually examined followed by sampling of lung tissue which were examined using microscopy.RESULTS: In the CCC group and the 30:2 group, peak inspiratory pressure (PIP) was 58.6 and 35.1 cmH2O (p < 0.001), minute volume (MV) 2189.6 and 1267.1 ml (p < 0.001), peak expired carbon dioxide (PECO2) 28.6 and 39.4 mmHg (p = 0.020), partial pressure of carbon dioxide (PaCO2) 50.2 and 61.1 mmHg (p = 0.013) and pH 7.3 and 7.2 (p = 0.029), respectively. Central venous pressure (CVP) decreased more over time in the 30:2 group (p = 0.023). All lungs were injured, but there were no differences between the groups.CONCLUSIONS: Ventilation during CCC resulted in a higher PIP, MV and pH and lower PECO2 and PaCO2, showing that ventilation mode during CPR can affect ventilation parameters and blood gases.

(författare) Physiological respiratory parameters in pre-hospital patients with suspected COVID-19 : A prospective cohort study 2021 Ingår i: PLOS ONE. - : Public Library of Science (PLoS). - 1932-6203. ; 16:9 Tidskriftsartikel (refereegranskat)abstract Background The COVID-19 pandemic has presented emergency medical services (EMS) worldwide with the difficult task of identifying patients with COVID-19 and predicting the severity of their illness. The aim of this study was to investigate whether physiological respiratory parameters in pre-hospital patients with COVID-19 differed from those without COVID-19 and if they could be used to aid EMS personnel in the prediction of illness severity. Methods Patients with suspected COVID-19 were included by EMS personnel in Uppsala, Sweden. A portable respiratory monitor based on pneumotachography was used to sample the included patient's physiological respiratory parameters. A questionnaire with information about present symptoms and background data was completed. COVID-19 diagnoses and hospital admissions were gathered from the electronic medical record system. The physiological respiratory parameters of patients with and without COVID-19 were then analyzed using descriptive statistical analysis and logistic regression. Results Between May 2020 and January 2021, 95 patients were included, and their physiological respiratory parameters analyzed. Of these patients, 53 had COVID-19. Using adjusted logistic regression, the odds of having COVID-19 increased with respiratory rate (95% CI 1.000-1.118), tidal volume (95% CI 0.996-0.999) and negative inspiratory pressure (95% CI 1.017-1.152). Patients admitted to hospital had higher respiratory rates (p<0.001) and lower tidal volume (p = 0.010) compared to the patients who were not admitted. Using adjusted logistic regression, the odds of hospital admission increased with respiratory rate (95% CI 1.081-1.324), rapid shallow breathing index (95% CI 1.006-1.040) and dead space percentage of tidal volume (95% CI 1.027-1.159). Conclusion Patients taking smaller, faster breaths with less pressure had higher odds of having COVID-19 in this study. Smaller, faster breaths and higher dead space percentage also increased the odds of hospital admission. Physiological respiratory parameters could be a useful tool in detecting COVID-19 and predicting hospital admissions, although more research is needed.

(författare) Reinfarction in patients with myocardial infarction with non-obstructive coronary arteries (MINOCA) : coronary findings and prognosis 2019 Ingår i: American Journal of Medicine. - : Elsevier. - 0002-9343 .- 1555-7162. ; 132:3, s. 335-346 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Myocardial infarction (MI) with non-obstructive coronary arteries (MINOCA) is common. There are limited data on the mechanisms and prognosis for reinfarction in MINOCA patients.METHODS: In this observational study of MINOCA patients hospitalized in Sweden and registered in the SWEDEHEART registry between July 2003 and June 2013 and followed until December 2013 we identified 9,092 unique patients with MINOCA out of 199,163 MI admissions in total. The 570 (6.3%) MINOCA patients who were hospitalized due to a recurrent MI constituted the study group.RESULTS: The mean age was 69.1 years and 59.1% were women. The median time to readmission was 17 months. A total of 340 patients underwent a new coronary angiography and 180 (53%) had no obstructive coronary artery disease (CAD) and 160 (47%) had obstructive CAD; 123 had one-vessel, 26 had two-vessel, 9 had three-vessel disease and two had left main together with one-vessel disease. Male gender, diabetes, peripheral vascular disease, higher levels of creatinine and ST-elevation at presentation were more common in patients with MI with obstructive CAD than in patients with a recurrent MINOCA. Mortality during a median follow-up of 38 months was similar whether the reinfarction event was MINOCA or MI with obstructive CAD 13.9% vs. 11.9% (p=0.54).CONCLUSIONS: About half of patients with reinfarction after MINOCA who underwent coronary angiography had progression of coronary stenosis. Angiography should be strongly considered in patients with MI after MINOCA. Mortality associated with recurrent events was substantial, though there was no difference in mortality between those with or without significant CAD.

(författare) Unrecognized myocardial infarction assessed by cardiac magnetic resonance imaging : prognostic implications 2016 Ingår i: PLOS ONE. - : Public Library Science. - 1932-6203. ; 11:2 Tidskriftsartikel (refereegranskat)abstract Background: Clinically unrecognized myocardial infarctions (UMI) are not uncommon and may be associated with adverse outcome. The aims of this study were to determine the prognostic implication of UMI in patients with stable suspected coronary artery disease (CAD) and to investigate the associations of UMI with the presence of CAD.Methods and Findings: In total 235 patients late gadolinium enhancement cardiovascular magnetic resonance (LGE-CMR) imaging and coronary angiography were performed. For each patient with UMI, the stenosis grade of the coronary branch supplying the infarcted area was determined. UMIs were present in 25% of the patients and 67% of the UMIs were located in an area supplied by a coronary artery with a stenosis grade >= 70%. In an age-and gender-adjusted model, UMI independently predicted the primary endpoint (composite of death, myocardial infarction, resuscitated cardiac arrest, hospitalization for unstable angina pectoris or heart failure within 2 years of follow-up) with an odds ratio of 2.9; 95% confidence interval 1.1-7.9. However, this association was abrogated after adjustment for age and presence of significant coronary disease. There was no difference in the primary endpoint rates between UMI patients with or without a significant stenosis in the corresponding coronary artery.Conclusions: The presence of UMI was associated with a threefold increased risk of adverse events during follow up. However, the difference was no longer statistically significant after adjustments for age and severity of CAD. Thus, the results do not support that patients with suspicion of CAD should be routinely investigated by LGE-CMR for UMI. However, coronary angiography should be considered in patients with UMI detected by LGE-CMR.

The objective of this study was to determine the association between levels of cardiac biomarkers, UMI and extent of CAD in patients with stable CAD.Methods: A total of 235 patients (median age: 65 years; 34% women) with stable CAD without previously known myocardial infarction were examined with late gadolinium enhancement cardiovascular magnetic resonance imaging and coronary angiography. Blood samples were drawn at enrolment and high sensitivity cardiac troponin I (cTnI), NT-proBNP and Galectin-3 were analyzed.Results: UMI was detected in 58 patients (25%). The median levels of cTnI, NT-proBNP and Galectin-3 were significantly higher in patients with UMI compared to those without, (p < 0.001, p = 0.006 and p = 0.033, respectively). After adjustment for cardiovascular risk factors, left ventricular ejection fraction and renal function, cTnI remained independently associated with the presence of UMI (p = 0.031) and the extent of CAD (p = 0.047). Neither NT-proBNP, nor Galectin-3, was independently associated with UMI or extent of CAD.Conclusions: The independent association between levels of cTnI and UMI indicates a common pathophysiological pathway for the cTnI elevation and development of UMI.

However, it is not known whether individual questions used for SRBD screening are associated with major adverse CV events (MACE) and death specifically in patients with chronic coronary syndrome (CCS).Methods Symptoms associated with SRBD were assessed by a baseline questionnaire in 15,640 patients with CCS on optimal secondary preventive therapy in the STABILITY trial. The patients reported the frequency (never/rarely, sometimes, often and always) of: 1) loud snoring; 2) more than one awakening/night; 3) morning tiredness (MT); 4) excessive daytime sleepiness (EDS); or 5) gasping, choking or apnoea when asleep. In adjusted Cox regression models, associations between the frequency of SRBD symptoms and CV outcomes were assessed with never/rarely as reference.Results During a median follow-up time of 3.7 years, 1,588 MACE events (541 CV deaths, 749 nonfatal myocardial infarctions [MI] and 298 nonfatal strokes) occurred. EDS was associated (hazard ratio [HR], 95% confidence interval [CI]) with increased risk of MACE (sometimes 1.14 [1.01-1.29], often 1.19 [1.01-1.40] and always 1.43 [1.15-1.78]), MI (always 1.61 [1.17-2.20]) and all-cause death (often 1.26 [1.05-1.52] and always 1.71 [1.35-2.15]). MT was associated with higher risk of MACE (often 1.23 [1.04-1.45] and always 1.46 [1.18-1.81]), MI (always 1.61 [1.22-2.14]) and all-cause death (always 1.54 [1.20-1.98]). The other SRBD-related questions were not consistently associated with worse outcomes.Conclusions In patients with CCS, gradually higher levels of EDS and MT were independently associated with increased risk of MACE, including mortality.

Tidskriftsartikel (refereegranskat)abstract BackgroundSleep-related breathing disorders (SRBD) are related to cardiovascular outcomes in patients with chronic coronary syndrome (CCS). Whether SRBD-related symptoms are associated with prognostic biomarkers in patients with CCS is not established.MethodsAssociations between frequency (never/rarely, sometimes, often, always) of self-reported SRBD-related symptoms (excessive daytime sleepiness [EDS]; morning tiredness [MT]; loud snoring; multiple awakenings/night; gasping, choking, or apnea when asleep) and levels of biomarkers related to cardiovascular prognosis (high-sensitivity C-reactive protein [hs-CRP], interleukin 6 [IL-6], high-sensitivity cardiac troponin T [hs-cTnT], N-terminal pro B-type natriuretic peptide [NT-proBNP], cystatin C, growth differentiation factor 15 [GDF-15] and lipoprotein-associated phospholipase A2 activity) were assessed at baseline in 15,640 patients with CCS on optimal secondary preventive therapy in the STABILITY trial. Cross-sectional associations were assessed by adjusted linear regression models testing for trends with the never/rarely category serving as reference.ResultsEDS was associated (geometric mean ratio, 95% confidence interval) with increased levels of IL-6 (often 1.07 [1.03–1.10], always 1.15 [1.10–1.21]), GDF-15 (often 1.03 [1.01–1.06], always 1.07 [1.03–1.11]), NT-proBNP (always 1.22 [1.12–1.33]), and hs-cTnT (always 1.07 [1.01–1.12]). MT was associated with increased levels of IL-6 (often 1.05 [1.01–1.09], always 1.09 [1.04–1.15]), and GDF-15 (always 1.06 [1.03–1.10]). All symptoms were to some degree associated with higher levels of hs-CRP and loud snoring was also associated with decreased levels of NT-proBNP and hs-cTnT.ConclusionsIn patients with CCS, stepwise increased frequency of SRBD-related symptoms, such as EDS and MT, were associated with gradually higher levels of IL-6 and GDF-15, each reflecting distinct pathophysiological pathways.

(författare) In Vitro Fertilization/Intracytoplasmic Sperm Injection with Autologous Oocytes in Healthy Women of Advanced Maternal Age : A Comparative Study Investigating Obstetric and Perinatal Outcomes Through Single Versus Double Embryo Transfer 2024 Ingår i: Women's Health Reports. - : Mary Ann Liebert. - 2688-4844. ; 5:1, s. 512-521 Tidskriftsartikel (refereegranskat)abstract Introduction: The aim of this study was to assess whether the choice between double embryo transfer (DET) and single embryo transfer (SET) in healthy women of advanced maternal age (AMA) was associated with an increased risk of adverse outcomes.Materials and Methods: Healthy women aged 39-40 years who achieved live birth after in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) treatment between 2009 and 2020 at Karolinska University Hospital, Stockholm in Sweden, were included in this prospective, single-center cohort study.Results: A total of 310 women, who underwent IVF/ICSI treatments and achieved live births, were included in our analysis. Within this cohort, 78% of the women received SET, while 22% received DET. Nulliparity was common in both the SET (62.7%) and DET (85.3%) groups. Fresh embryo transfers were more prevalent in the DET group (91.2%) than in the SET group (31.1%). The rate of pregnancy-induced hypertension was higher in the SET group (8.3%) compared to the DET group (1.5%, p = 0.048). Furthermore, the DET group had a significantly higher rate of twin pregnancies (13.2%) compared to the SET group (0.4%). No statistically significant differences were observed in composite obstetric and perinatal complications between the SET and DET groups across all model estimates following different adjustments.Conclusions: While DET was more common in nulliparous women and associated with a higher rate of twin pregnancies, our analysis did not reveal significant differences in adverse outcomes between the SET and DET groups after comprehensive adjustments. Our study suggests that in the absence of co-morbidities, meticulous patient selection coupled with comprehensive maternal care can potentially mitigate potential DET-associated risks in women of AMA.
39.	Rhenman, Axel, et al. (författare) Which set of embryo variables is most predictive for live birth? : A prospective study in 6252 single embryo transfers to construct an embryo score for the ranking and selection of embryos 2015 Ingår i: Human Reproduction. - : Oxford University Press (OUP). - 0268-1161 .- 1460-2350. ; 30:1, s. 28-36 Tidskriftsartikel (refereegranskat)abstract STUDY QUESTION: Which embryo score variables are most powerful for predicting live birth after single embryo transfer (SET) at the early cleavage stage? SUMMARY ANSWER: This large prospective study of visual embryo scoring variables shows that blastomere number (BL), the proportion of mononucleated blastomeres (NU) and the degree of fragmentation (FR) have independent prognostic power to predict live birth. WHAT IS KNOWN ALREADY: Other studies suggest prognostic power, at least univariately and for implantation potential, for all five variables. A previous study from the same centre on double embryo transfers with implantation as the end-point resulted in the integrated morphology cleavage (IMC) score, which incorporates BL, NU and EQ. STUDY DESIGN, SIZE AND DURATION: A prospective cohort study of IVF/ICSI SET on Day 2 (n = 6252) during a 6-year period (2006-2012). The five variables (BL NU, FR, EQ and symmetry of cleavage (SY)) were scored in 3- to 5-step scales and subsequently related to clinical pregnancy and LBR. PARTICIPANTS/MATERIALS, SETTING, METHODS: A total of 4304 women undergoing IVF/ICSI in a university-affiliated private fertility clinic were included. Generalized estimating equation models evaluated live birth (yes/no) as primary outcome using the embryo variables as predictors. Odds ratios with 95% confidence intervals and P-values were presented for each predictor. The C statistic (i.e. area under receiver operating characteristic curve) was calculated for each model. Model calibration was assessed with the Hosmer-Lemeshow test. A shrinkage method was applied to remove bias in c statistics due to over-fitting. MAIN RESULTS AND THE ROLE OF CHANCE: LBR was 27.1% (1693/6252). BL, NU, FR and EQ were univariately highly significantly associated with LBR. In a multivariate model, BL, NU and FR were independently significant, with c statistic 0.579 (age-adjusted c statistic 0.637). EQ did not retain significance in the multivariate model. Prediction model calibration was good for both pregnancy and live birth. We present a ranking tree with combinations of values of the BL, NU and FR embryo variables for optimal selection of the embryo/s to transfer, providing a revised IMC score. The five embryo variables had similar effects over all age groups. LIMITATIONS, REASONS FOR CAUTION: Limitations of the present study are those inherent for real-time visual scoring, including risks of inter-observer variation and the hazards of fixed time-point scoring procedures in a dynamic process. The study is restricted to Day-2 transfers. WIDER IMPLICATIONS OF THE FINDINGS: To our knowledge this is the largest prospective, SET study performed with the explicit aim of constructing an evidence-based embryo score for the ranking and selection of early cleavage stage embryos. In line with previous research, our data suggest that the symmetry of cleavage variable may be omitted when scoring embryos in the early cleavage stage. We suggest that, following validation in other populations, the revised IMC score may be used when international standards for embryo scoring are discussed.

Associations between the volume of habitual exercise in metabolic equivalents of task hours/week and adverse outcomes during a median follow-up of 3.7 years were evaluated.RESULTS A graded decrease in mortality occurred with increased habitual exercise that was steeper at lower compared with higher exercise levels. Doubling exercise volume was associated with lower all-cause mortality (unadjusted hazard ratio [HR]: 0.82; 95% confidence interval [CI]: 0.79 to 0.85; adjusting for covariates, HR: 0.90; 95% CI: 0.87 to 0.93). These associations were similar for cardiovascular mortality (unadjusted HR: 0.83; 95% CI: 0.80 to 0.87; adjusted HR: 0.92; 95% CI: 0.88 to 0.96), but myocardial infarction and stroke were not associated with exercise volume after adjusting for covariates. The association between decrease in mortality and greater physical activity was stronger in the subgroup of patients at higher risk estimated by the ABC-CHD (Age, Biomarkers, Clinical-Coronary Heart Disease) risk score (p for interaction = 0.0007).CONCLUSIONS In patients with stable CHD, more physical activity was associated with lower mortality. The largest benefits occurred between sedentary patient groups and between those with the highest mortality risk.

At baseline, 98% ofparticipants completed a questionnaire that included the question, “Overall, how do you feel your general health is now?”Possible responses were excellent, very good, good, average, and poor. Adjudicated major adverse cardiac events, whichincluded cardiovascular death, myocardial infarction, and stroke, were evaluated by Cox regression during 3.7 years of follow-upfor participants who reported excellent or very good health (n=2304), good health (n=6863), and average or poor health(n=6361), before and after adjusting for 38 covariates. Self-reported health was most strongly associated with geographicregion, depressive symptoms, and low physical activity (P<0.0001 for all). Poor/average compared with very good/excellentself-reported health was independently associated with major adverse cardiac events (hazard ratio [HR]: 2.30 [95% confidenceinterval (CI), 1.92–2.76]; adjusted HR: 1.83 [95% CI, 1.51–2.22]), cardiovascular mortality (HR: 4.36 [95% CI, 3.09–6.16];adjusted HR: 2.15 [95% CI, 1.45–3.19]), and myocardial infarction (HR: 1.87 [95% CI, 1.46–2.39]; adjusted HR: 1.68 [95% CI,1.25–2.27]; P<0.0002 for all).Conclusions-—Self-reported health is strongly associated with geographical region, mood, and physical activity. In a globalcoronary heart disease population, self-reported health was independently associated with major cardiovascular events andmortality beyond what is measurable by established risk indicators.

We investigated the associations between clinical risk factors and biomarkers with incident AF in patients with CHD.Methods and resultsAround 13,153 patients with optimally treated CHD included in the STabilization of Atherosclerotic plaque By Initiation of darapLadIb TherapY (STABILITY) trial with plasma samples obtained at randomization. Mean follow-up time was 3.5 years. The association between clinical risk factors and biomarkers with incident AF was estimated with Cox-regression models. Validation was performed in 1,894 patients with non-ST-elevation acute coronary syndrome included in the FRISC-II trial.The median (min-max) age was 64 years (range 26-92) and 2,514 (19.1%) were women. A total of 541 patients, annual incidence rate of 1.2%, developed AF during follow-up. In multivariable models, older age, higher levels of NT-proBNP, higher body mass index (BMI), male sex, geographic regions, low physical activity, and heart failure were independently associated with increased risk of incident AF with hazard ratios ranging from 1.04 to 1.79 (P ≤ .05). NT-proBNP improved the C-index from 0.70 to 0.71. In the validation cohort, age, BMI, and NT-proBNP were associated with increased risk of incident AF with similar hazard ratios.ConclusionsIn patients with optimally treated CHD, the incidence of new AF was 1.2% per year. Age, NT-proBNP as a marker of impaired cardiac function, and BMI were the strongest factors, independently and consistently associated with incident AF. Male sex and low physical activity may also contribute to the risk of AF in patients with CHD.

(författare) Construction and validation of a prediction model to minimize twin rates at preserved high live birth rates after IVF 2019 Ingår i: Reproductive BioMedicine Online. - : Elsevier. - 1472-6483 .- 1472-6491. ; 38:1, s. 22-29 Tidskriftsartikel (refereegranskat)abstract Research question: Elective single-embryo transfer (eSET) at blastocyst stage is widely used to reduce the frequency of multiple pregnancies after IVF. There are, however, concerns about increased risks for the offspring with prolonged embryo culture. Is it possible to select embryos for transfer at the early cleavage stage and still achieve low twin rates at preserved high live birth rates? Design: A prediction model (PM) was developed to optimize eSET based on variables known 2 days after oocyte retrieval (fresh day 2 embryo transfers; double-embryo transfers 1999-2002 (n=2846) and SET 1999-2003 (n=945); n total=3791). Seventy-five variables were analysed for association with pregnancy chance and twin risk and combined for PM construction. This PM was validated in 2004-2016 including frozen-thawed transfers (FET), to compare cumulative live birth rate (CLBR) and twin rate before (1999-2002 fresh embryo transfers plus FET from the same oocyte retrievals until the end of 2007, n=3495) and after (2004-2011 fresh embryo transfers plus FET from the same oocyte retrievals until the end of 2016, n=11195) implementing the model. Results: The PM was constructed from four independent variables: female age, embryo score, ovarian sensitivity and treatment history. The calibration, i.e. the fit of observed versus predicted results, was excellent both at construction and at validation. Without compromising CLBR, twin rate was reduced from 25.2% to 3.8%, accompanied by profound improvements in perinatal outcome. Conclusion: The results provide the first successful construction, validation and impact analysis of a day 2 transfer PM to reduce multiple pregnancies.

This study was conducted to compare the outcomes of ART treatments in SW vs. WLR. Methods This is a prospective controlled cohort study of 251 women undergoing intrauterine insemination (D-IUI) or in vitro fertilization (D-IVF) using donor sperm between 2017 and 2019 at the department of Reproductive Medicine, Karolinska University Hospital. The cohort comprised 139 SW and 112 WLR. The main outcomes included differences in live birth rate (LBR) and cumulative live birth rate (cLBR) between the groups. The SW underwent 66 D-IUI and 193 D-IVF treatments and WLR underwent 255 D-IUI and 69 D-IVF treatments. Data on clinical characteristics, treatment protocols and clinical outcomes were extracted from the clinic's electronic database. The outcomes of D-IUI and D-IVF were separately assessed. Results The cohort of SW was significantly older than WLR (37.6 vs. 32.4 years, P < 0.001), and more commonly underwent IVF at first treatment (83% vs. 29%, P < 0.000). Conversely, WLR underwent more frequently D-IUI as a first treatment (71% vs. 17% of SW, P < 0.001) and more often in the natural cycle (89.9% vs. 70.8%, P = 0.019), respectively. There was no statistically significant difference in the main outcome LBR between the two groups, or between the two different types of treatment, when adjusted for age. Perinatal outcomes and cLBR were also similar among the groups. Conclusions SW were, on average, older than WLR undergoing treatment with donor sperm. No significant differences were seen in the LBR and cLBR when adjusted for age between the two groups and between the two types of treatment (D-IVF vs. D-IUI).
