2.	Meehan, Adrian D., 1973-, et al. (författare) The prevalence of lithium-associated hyperparathyroidism in a large Swedish population attending psychiatric outpatient units 2015 Ingår i: Journal of Clinical Psychopharmacology. - 0271-0749 .- 1533-712X. ; 35:3, s. 279-285 Tidskriftsartikel (refereegranskat)abstract Objective: This retrospective study determined the prevalence of lithium-associated hyperparathyroidism (LHPT) in 2 geographically defined, equivalent populations in Sweden, with no other selection bias.Methods: The medical journals of all patients receiving lithium treatment were examined specifically regarding their biochemistry: calcium, parathyroid hormone (PTH), creatinine, and vitamin D. The condition LHPT was defined biochemically. All patient data were noted, and the prevalence of the condition could thereby be calculated.Results: A total of 423 patients were included (251 women and 172 men; 3: 2), treated over a mean of 13.5 years (range, 1-46 years), aged 19 to 92. 77 patients (18%) were identified with LHTP whose median serum calcium-was 2.55 mmol/L and PTH was 99 ng/L. A further 21% showed tendencies toward hypercalcemia. Forty-three percent had vitamin D insufficiency. Five patients (approximately 1%) had undergone parathyroidectomy.Conclusion: The prevalence of LHPT is high and often goes undetected. Vitamin D insufficiency is common as is polypharmacy. Surgery, for unclear reasons, has not been performed extensively, possibly because of limited knowledge of the underlying pathophysiology or surgery's significance. We present standard recommendations on patient management and suggest continual, specific follow-up including the monitoring of calcium, PTH, and vitamin D at least annually. Surgery should be considered with intention to improve psychiatric well-being and provide multiorgan protection.
3.	Ahl, Rebecka, 1987-, et al. (författare) Does beta-blockade reduce the risk of depression in patients with isolated severe extracranial injuries? 2017 Ingår i: World Journal of Surgery. - New York : Springer. - 0364-2313 .- 1432-2323. ; 41:7, s. 1801-1806 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Approximately half of trauma patients develop post-traumatic depression. It is suggested that beta-blockade impairs trauma memory recollection, reducing depressive symptoms. This study investigates the effect of early beta-blockade on depression following severe traumatic injuries in patients without significant brain injury.METHODS: Patients were identified by retrospectively reviewing the trauma registry at an urban university hospital between 2007 and 2011. Severe extracranial injuries were defined as extracranial injuries with Abbreviated Injury Scale score ≥3, intracranial Abbreviated Injury Scale score <3 and an Injury Severity Score ≥16. In-hospital deaths and patients prescribed antidepressant therapy ≤1 year prior to admission were excluded. Patients were stratified into groups based on pre-admission beta-blocker status. The primary outcome was post-traumatic depression, defined as receiving antidepressants ≤1 year following trauma.RESULTS: Five hundred and ninety-six patients met the inclusion criteria with 11.4% prescribed pre-admission beta-blockade. Patients receiving beta-blockers were significantly older (57 ± 18 vs. 42 ± 17 years, p < 0.001) with lower Glasgow Coma Scale score (12 ± 3 vs. 14 ± 2, p < 0.001). The beta-blocked cohort spent significantly longer in hospital (21 ± 20 vs. 15 ± 17 days, p < 0.01) and intensive care (4 ± 7 vs. 3 ± 5 days, p = 0.01). A forward logistic regression model was applied and predicted lack of beta-blockade to be associated with increased risk of depression (OR 2.7, 95% CI 1.1-7.2, p = 0.04). After adjusting for group differences, patients lacking beta-blockers demonstrated an increased risk of depression (AOR 3.3, 95% CI 1.2-8.6, p = 0.02).CONCLUSIONS: Pre-admission beta-blockade is associated with a significantly reduced risk of depression following severe traumatic injury. Further investigation is needed to determine the beneficial effects of beta-blockade in these instances.
4.	Ahl, Rebecka, 1987-, et al. (författare) Effects of beta-blocker therapy on mortality after elective colon cancer surgery : a Swedish nationwide cohort study 2020 Ingår i: BMJ Open. - : BMJ Publishing Group Ltd. - 2044-6055. ; 10:7 Tidskriftsartikel (refereegranskat)abstract OBJECTIVE: Colon cancer surgery remains associated with substantial postoperative morbidity and mortality despite advances in surgical techniques and care. The trauma of surgery triggers adrenergic hyperactivation which drives adverse stress responses. We hypothesised that outcome benefits are gained by reducing the effects of hyperadrenergic activity with beta-blocker therapy in patients undergoing colon cancer surgery. This study aims to test this hypothesis.DESIGN: Retrospective cohort study.SETTING AND PARTICIPANTS: This is a nationwide study which includes all adult patients undergoing elective colon cancer surgery in Sweden over 10 years. Patient data were collected from the Swedish Colorectal Cancer Registry. The national drugs registry was used to obtain information about beta-blocker use. Patients were subdivided into exposed and unexposed groups. The association between beta-blockade, short-term and long-term mortality was evaluated using Poisson regression, Kaplan-Meier curves and Cox regression.PRIMARY AND SECONDARY OUTCOMES: Primary outcome of interest was 1-year all-cause mortality. Secondary outcomes included 90-day all-cause and 5-year cancer-specific mortality.RESULTS: The study included 22 337 patients of whom 36.1% were prescribed preoperative beta-blockers. Survival was higher in patients on beta-blockers up to 1 year after surgery despite this group being significantly older and of higher comorbidity. Regression analysis demonstrated significant reductions in 90-day deaths (IRR 0.29, 95% CI 0.24 to 0.35, p<0.001) and a 43% risk reduction in 1-year all-cause mortality (adjusted HR 0.57, 95% CI 0.52 to 0.63, p<0.001) in beta-blocked patients. In addition, cancer-specific mortality up to 5 years after surgery was reduced in beta-blocked patients (adjusted HR 0.80, 95% CI 0.73 to 0.88, p<0.001).CONCLUSION: Preoperative beta-blockade is associated with significant reductions in postoperative short-term and long-term mortality following elective colon cancer surgery. Its potential prophylactic effect warrants further interventional studies to determine whether beta-blockade can be used as a way of improving outcomes for this patient group.
5.	Ahl, Rebecka, 1987- (författare) The Association Between Beta-Blockade and Clinical Outcomes in the Context of Surgical and Traumatic Stress 2019 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Traumatic injury and major abdominal surgery are areas in general surgery associated with high rates of morbidity and mortality. The overall colorectal cancer surgery mortality rate is around 4%, with that for emergency surgery more than twice as high as for planned. Surgical morbidity varies between 25% and 45%. Around half of trauma patients develop low mood. In one quarter of patients this becomes permanent. Depression is known to impede physical rehabilitation and recovery. The onset of physiological stress, driven by adrenergic hyperactivity following traumatic and surgical injury is hypothesized to contribute to these adverse outcomes. Interest has therefore been sparked into blocking adrenergic receptor activation.Papers I and II investigated the role of beta-blocker therapy in preventing post-traumatic depression following severe traumatic brain injury (Paper I) and severe extracranial injury (Paper II). The Karolinska University Hospital Trauma Registry was used to identify patients admitted between 2007 and 2011. In Paper I (n = 545), patients on pre-injury beta-blocker therapy were matched to beta-blocker naïve patients with equivalent injury burden. Results revealed that beta-blocked patients exhibited a 60% reduced risk of needing antidepressant therapy within one year of trauma. In Paper II (n = 596), the lack of beta-blocker use before extracranial trauma was linked to a three-fold increase in the risk of antidepressant initiation.Papers III-V explored the role of pre-operative beta-blocker therapy in patients undergoing surgery for colorectal cancer between 2007 and 2016, identified using the nationwide Swedish Colorectal Cancer Registry. Paper III (n = 3,187) identified a 69% reduction in the risk of 30-day mortality in beta-blocked patients. Paper IV (n = 22,337) outlined long-term survival benefits for patients on beta-blocker therapy prior to undergoing elective surgery for colon cancer. Beta-blocked patients showed a risk reduction of 42% for 1-year all-cause mortality and 18% for 5-year cancerspecific mortality. Similarly, patients on beta-blocker therapy who underwent surgery for rectal cancer demonstrated improved survival up to one year after surgery with a risk reduction of 57% and a reduction in anastomotic failure and infectious complications in Paper V (n = 11,966).

7.	Aktypis, Charalampos, et al. (författare) Cardiovascular Toxicities Secondary to Biotherapy and Molecular Targeted Therapies in Neuroendocrine Neoplasms : A Systematic Review and Meta-Analysis of Randomized Placebo-Controlled Trials. 2021 Ingår i: Cancers. - : MDPI. - 2072-6694. ; 13:9 Forskningsöversikt (refereegranskat)abstract A broad spectrum of novel targeted therapies with prime antitumor activity and/or ample control of hormonal symptoms together with an overall acceptable safety profile have emerged for patients with metastatic neuroendocrine neoplasms (NENs). In this systematic review and quantitative meta-analysis, the PubMed, EMBASE, Cochrane Central Register of Controlled Trials and clinicaltrials.gov databases were searched to assess and compare the safety profile of NEN treatments with special focus on the cardiovascular adverse effects of biotherapy and molecular targeted therapies (MTTs). Quality/risk of bias were assessed using GRADE criteria. Placebo-controlled randomized clinical trials (RCTs) in patients with metastatic NENs, including medullary thyroid cancer (MTC) were included. A total of 3695 articles and 122 clinical trials registered in clinicaltrials.gov were screened. We included sixteen relevant RCTs comprising 3408 unique patients assigned to different treatments compared with placebo. All the included studies had a low risk of bias. We identified four drug therapies for NENs with eligible placebo-controlled RCTs: somatostatin analogs (SSAs), tryptophan hydroxylase (TPH) inhibitors, mTOR inhibitors and tyrosine kinase inhibitors (TKI). Grade 3 and 4 adverse effects (AE) were more often encountered in patients treated with mTOR inhibitors and TKI (odds ratio [OR]: 2.42, 95% CI: 1.87-3.12 and OR: 3.41, 95% CI: 1.46-7.96, respectively) as compared to SSAs (OR:0.77, 95% CI: 0.47-1.27) and TPH inhibitors (OR:0.77, 95% CI: 0.35-1.69). MTOR inhibitors had the highest risk for serious cardiac AE (OR:3.28, 95% CI: 1.66-6.48) followed by TKIs (OR:1.51, 95% CI: 0.59-3.83). Serious vascular AE were more often encountered in NEN patients treated with mTOR inhibitors (OR: 1.72, 95% CI: 0.64-4.64) and TKIs (OR:1.64, 95% CI: 0.35-7.78). Finally, patients on TKIs were at higher risk for new-onset or exacerbation of pre-existing hypertension (OR:3.31, 95% CI: 1.87-5.86). In conclusion, SSAs and TPH inhibitors appear to be safer as compared to mTOR inhibitors and TKIs with regards to their overall toxicity profile, and cardiovascular toxicities in particular. Special consideration should be given to a patient-tailored approach with anticipated toxicities of targeted NEN treatments together with assessment of cardiovascular comorbidities, assisting clinicians in treatment selection and early recognition/management of cardiovascular toxicities. This approach could improve patient compliance and preserve cardiovascular health and overall quality of life.
8.	Alevroudis, Emmanouil, et al. (författare) Clinical utility of 18f-fdg pet in neuroendocrine tumors prior to peptide receptor radionuclide therapy : A Systematic Review and Meta-Analysis 2021 Ingår i: Cancers. - : MDPI. - 2072-6694. ; 13:8 Forskningsöversikt (refereegranskat)abstract The role of 18F-FDG PET in patients with variable grades of neuroendocrine tumors (NETs) prior to peptide receptor radionuclide therapy (PRRT) has not been adequately elucidated. We aimed to evaluate the impact of 18F-FDG PET status on disease control rate (DCR), progression-free survival (PFS), and overall survival (OS) in neuroendocrine tumor (NET) patients receiving PRRT. We searched the MEDLINE, Embase, Cochrane Library, and Web of Science databases up to July 2020 and used the Newcastle-Ottawa scale (NOS) criteria to assess quality/risk of bias. A total of 5091 articles were screened. In 12 studies, 1492 unique patients with NETs of different origins were included. The DCR for patients with negative 18F-FDG PET status prior to PRRT initiation was 91.9%, compared to 74.2% in patients with positive 18F-FDG PET status (random effects odds ratio (OR): 4.85; 95% CI: 2.27–10.36). Adjusted analysis of pooled hazard ratios (HRs) confirmed longer PFS and OS in NET patients receiving PRRT with negative 18F-FDG PET (random effects HR:2.45; 95%CIs: 1.48–4.04 and HR:2.25; 95% CIs:1.55–3.28, respectively). In conclusion, 18F-FDG PET imaging prior to PRRT administration appears to be a useful tool in NET patients to predict tumor response and survival outcomes and a negative FDG uptake of the tumor is associated with prolonged PFS and OS.
9.	Ali, Fathalla, 1963-, et al. (författare) Effect of the SARS-CoV-2 pandemic on planned and emergency hernia repair in Sweden : a register-based study 2023 Ingår i: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 27:5, s. 1103-1108 Tidskriftsartikel (refereegranskat)abstract PURPOSE: The COVID-19 has had a profound impact on the health care delivery in Sweden, including deprioritization of benign surgeries during the COVID-19 pandemic. The aim of this study was to assess the effect of COVID-19 pandemic on emergency and planned hernia repair in Sweden.METHODS: Data on hernia repairs from January 2016 to December 2021 were retrieved from the Swedish Patient Register using procedural codes. Two groups were formed: COVID-19 group (January 2020-December 2021) and control group (January 2016-December 2019). Demographic data on mean age, gender, and type of hernia were collected.RESULTS: This study showed a weak negative correlation between the number of elective hernia repairs performed each month during the pandemic and the number of emergency repairs carried out during the following 3 months for inguinal hernia repair (p = 0.114) and incisional hernia repair (p = 0.193), whereas there was no correlation for femoral or umbilical hernia repairs.CONCLUSION: The COVID-19 pandemic had a great impact on planned hernia surgeries in Sweden, but our hypothesis that postponing planned repairs would increase the risk of emergency events was not supported.
10.	Ali, Fathalla, 1963-, et al. (författare) Laparoscopic ventral and incisional hernia repair using intraperitoneal onlay mesh with peritoneal bridging 2022 Ingår i: Hernia. - : Springer. - 1265-4906 .- 1248-9204. ; 26:2, s. 635-646 Tidskriftsartikel (refereegranskat)abstract Purpose: The aim of this study was to assess the feasibility and safety of a novel IPOM procedure with peritoneal bridging (IPOM-pb) for laparoscopic ventral hernia repair, and to compare the outcomes of this procedure with IPOM with- (IPOM-plus) and IPOM without (sIPOM) defect closure.Method: A single-centre retrospective study comparing a novel IPOM technique with peritoneal bridging (IPOM-pb) with the two commonly used IPOM techniques, IPOM with defect closure (IPOM-plus) and without defect closure (sIPOM). The intraoperative and postoperative data of patients who underwent laparoscopic IPOM ventral hernia repair were reviewed. Preoperative data, recurrence, and postoperative seroma, surgical site infection, and pain, were compared.Results: From January 2017 to June 2020, a total of 213 patients underwent laparoscopic ventral and incisional hernia repair with IPOM technique. The mean length and width of the ventral hernia was 4.4 +/- 1.8 cm and 3.6 +/- 1.4 cm, respectively, and the mean BMI was 30.1 +/- 5.2 kg/m(2). The mean operating time was 67 +/- 28 min and was longer for IPOM-pb (71 +/- 27 min), less for IPOM-plus (63 +/- 28 min), and least for sIPOM (61 +/- 26 min). The incidence of early postoperative seroma was least in IPOM-pb (1/98, 1%), and similar in the IPOM-plus (4/94, 4%) and sIPOM (1/21, 5%) group. Late postoperative seroma was found only in IPOM-plus (2, 2%). The incidence of early and late postoperative pain was relatively higher in sIPOM (3, 14%; 1, 5%, respectively) compared to IPOM-pb and IPOM-plus in the early (5, 5% and 6, 6%) and late (2, 2% and 1, 1%) postoperative period, respectively. Surgical site infection was higher in sIPOM group (3, 14%), compared to IPOM-pb (1, 1%), and IPOM-plus (3, 3%). Recurrence rates were similar in IPOM-pb group (3/98, 3%) and IPOM-plus (3/94, 3%), and none in sIPOM (0/21).Conclusion: IPOM with peritoneal bridging is as feasible and safe as conventional IPOM with defect closure and simple non-defect closure. However, a large randomised controlled trial is required to confirm this finding.
11.	Ali, Fathalla, 1963-, et al. (författare) Peritoneal bridging versus fascial closure in laparoscopic intraperitoneal onlay ventral hernia mesh repair : a randomized clinical trial 2020 Ingår i: BJS Open. - : John Wiley & Sons. - 2474-9842. ; 4:4, s. 587-592 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Many patients develop seroma after laparoscopic ventral hernia repair. It was hypothesized that leaving the hernial sac in situ may cause this complication.METHODS: In this patient- and outcome assessor-blinded, parallel-design single-centre trial, patients undergoing laparoscopic intraperitoneal onlay mesh ventral hernia repair were randomized (1 : 1) to either conventional fascial closure or peritoneal bridging. The primary endpoint was the incidence of seroma 12 months after index surgery detected by CT, evaluated in an intention-to-treat analysis.RESULTS: Between September 2017 and May 2018, 62 patients were assessed for eligibility, of whom 25 were randomized to conventional closure and 25 to peritoneal bridging. At 3 months, one patient was lost to follow-up in the conventional and peritoneal bridging groups respectively. No seroma was detected at 6 or 12 months in either group. The prevalence of clinical seroma was four of 25 (16 (95 per cent c.i. 2 to 30) per cent) versus none of 25 patients in the conventional fascial closure and peritoneal bridging groups respectively at 1 month after surgery (P = 0·110), and two of 24 (8 (0 to 19) per cent) versus none of 25 at 3 months (P = 0·235). There were no significant differences between the groups in other postoperative complications (one of 25 versus 0 of 25), rate of recurrent hernia within 1 year (none in either group) or postoperative pain.CONCLUSION: Conventional fascial closure and peritoneal bridging did not differ with regard to seroma formation after laparoscopic ventral hernia repair.TRIAL REGISTRATION: ClinicalTrials.gov (NCT03344575).
12.	Ali, Fathalla, 1963-, et al. (författare) Peritoneal Bridging Versus Nonclosure in Laparoscopic Ventral Hernia Repair 2023 Ingår i: Annals of Surgery Open. - : Wolters Kluwer. - 2691-3593. ; 4:1 Tidskriftsartikel (refereegranskat)abstract Introduction: Postoperative seroma and pain are common problems following laparoscopic intraperitoneal onlay mesh (IPOM) repair of ventral hernias. These advers outcomes may be avoided by dissecting and using the peritoneum in the hernial sac to bridge the hernia defect.Methods: This was a patient- an and outcome assesor-blinded, parallel-design, randomized controlled trial compairing nonclosure and peritoeal bridging approaches in patients schedueled for elective midline ventral hernia repair. The primary end point was seroma volume on ultrasonography. The secondary end points were postoperative pain, recurrence, and complications.Results: Between November 2018 and December 2020, 112 patients were randomized of whom 60 were in the nonclosure group and 52 were in the peritoneal bridging group. The seroma volume in the nonclosure and peritoneal bridging groups were 17cm3(6-53cm3) versus 0cm3(0-26cm3) at 1-moth follow-up (P=0.013). The median volume was zero at 3-, 6-, and 12-month follow-ups in both groups. No significant differences were observed in early postoperative pain (P=0.447) and in recurrencerate (P=0.684). There were 4(7%) and 1(2%) perioperative complictions that lead to reoperations in simple IPOM(sIPOM) and IPOM with peritoneal bridging (IPOM-pb), respectively.Conclusion: Seroma was less prevalent after IPOM-pb at 1-month follow-up compaired with sIPOM, with simillar posoperative pain 1 week after index of surgery in both groups. At subsequent follow-ups, the differences in seroma were not statiscally significant. Further studies are required to confirm these results.

13.	Dahle, B., et al. (författare) Predation on adult moose Alces alces by European brown bears Ursus arctos 2013 Ingår i: Wildlife Biology. - : Wiley. - 0909-6396 .- 1903-220X. ; 19:2, s. 165-169 Tidskriftsartikel (refereegranskat)abstract Several North American studies have reported significant predation rates on moose Alces alces by brown bears Ursus arctos. We documented predation on moose by brown bears in south-central Sweden, where brown bears and moose occurred at estimated densities of 10-30 and 400-1,340/1,000 km(2), respectively. Bears killed 0.8% of radio-collared adult female moose (i.e. >= 1 year old) annually and no male moose (>= 1 year old). Bear predation was the least important mortality factor we documented. Based on tracking brown bears on snow during spring we recorded one successful hunt for every 372 km of tracks and documented attacks only by adult bears and successful attacks only by adult males. Autopsy of moose older than calves that were killed by brown bears revealed that yearlings were more prone to predation than older moose, and that older (i.e. >= 2 years) cows were more vulnerable to predation than older bulls. Our study suggests a lower tendency for Scandinavian brown bears to prey on moose compared to most of the North American studies.
14.	Daskalakis, Kosmas, 1979-, et al. (författare) MODIFIED HISTOPATHOLOGICAL GRADING OPTIMIZES PREDICTION OF SURVIVAL OUTCOMES IN SMALL INTESTINAL NEUROENDOCRINE TUMOURS 2024 Ingår i: British Journal of Surgery. - : Oxford University Press. - 0007-1323 .- 1365-2168. ; 111:Suppl. 4 Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract Background: We aimed to identify optimal grading Ki-67 cut-offs to delineate differences in prognosis of patients with small intestinal neuroendocrine tumours (SI-NETs) in terms of overall- and event-free survival rates.Methods: We included 551 patients with SI-NETs diagnosed from June 15th, 1993, through March 8th, 2021, identified using the SI-NET databases from five European referral centers.Results: Median age at baseline was 62.3(17-90) years; 252 patients were women (45.7%). All tumours were well-differentiated; 326 were G1 tumours (59.2%), 169 G2(30.7%), only 8 G3(1.5%), while 48 tumourswere of unspecified grade (8.7%). The median Ki67 was 2%(1-70%). 247 patients(44.8%) had distant metastases at baseline (stage IV), 217locoregional disease (41.1%; stage III), whereas 29(7.1%) and 25(4.5%) presented at stages II and I, respectively. Within a mean(SD) follow-up of 51.5(52.9) months, 94 patients(17.1%) died, whereas overall 188 experienced disease recurrence, progression and/or death(34.1%). The median OS was 214.7(95%CI: 152.7-276.6) months and the median EFS was 79.8(95%CI: 68.2-91.5) months, respectively. In multivariable Cox-regression OS analysis, age (HR=1.07, 95%CI: 1.04-1.09; p<0.001), Charlson Comorbidity Index(HR=1.1, 95%CI: 1.03-1.17; p=0.006) and the proposed modified histopathological Ki67 grading system(K67:5-10% group: HR=2.4, 95%CI: 1.3-4.5; p=0.007 and K67≥10% group: HR=5.1, 95%CI: 2.9-9.2; p<0.001) were independent predictors for death. Pertinent EFS analysis, confirmed age(HR=1.04, 95%CI: 1.02-1.05;p<0.001) and the proposed modified histopathological Ki67 grading system(K67≥10% group: HR=4; 95%CI:2.5-6.2;p<0.001) as independent predictors for recurrence, progression and/or death.Conclusions: Ki-67 proliferation index is an independent predictor of EFS and OS. A modified site-specific histopathological grading system applying Ki-67 cut-offs of 5% and 10% seems more optimal to predict differences in SI-NET patient prognosis

16.	Dehlaghi Jadid, Kaveh, 1985- (författare) Long-term outcome, socioeconomic aspects and postoperative inflammatory response in minimally invasive rectal cancer surgery 2024 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract In Sweden, more than 2,200 individuals are diagnosed with rectal cancer each year and surgical resection is the cornerstone of treatment. Minimally invasive surgery (MIS) was introduced for abdominal rectal cancer resection in the 1990s. Proven advantages of MIS in the short term include less intraoperative bleeding, less postoperative pain, faster postoperative mobilization, and shorter hospital stay. Large randomized studies have also shown that MIS is not inferior to OPEN with regard to the oncological short-term or long-term outcome.The aim of this thesis was to increase the knowledge of MIS from a Swedish perspective regarding long-term oncological outcome, socioeconomic aspects, and the postoperative inflammatory response in curative abdominal rectal cancer surgery.Study I included all patients who were diagnosed with clinical stage I-III rectal cancer during 2010-2016. More than 8,300 patients were identified via the Swedish Colorectal Cancer Registry (SCRCR). The study had a so-called non-inferiority design and investigated overall 5-year survival. The results showed that survival was not worse in patients who underwent minimally invasive surgery in comparison to patients who underwent open surgery.Study II included all patients who were diagnosed with pathological stage I-III cancer of the colon 2010-2016. More than 11,000 patients were identified via the SCRCR. The study was designed in the same way as Study I. The results demonstrated that minimally invasive surgery was not inferior to open surgery.Study III analysed the potential impact of socioeconomic status, measured as level of education and household income, regarding the likelihood of receiving minimally invasive surgery. All patients who underwent curative abdominal rectal resection surgery during 2010-2016 were included. More than 8,000 patients were identified. The results showed that patients with the highest level of education and those in the highest income quartile were more likely to be operated on with minimally invasive technique.Study IV analysed the inflammatory response, measured as serum C-reactive protein during postoperative days 1-5, in all 520 patients undergoing abdominal rectal resection in Örebro between 2011 and 2021. Following exclusions based on postoperative adverse events, 382 patients remained for final analysis. The study demonstrated a trend for a less pronounced inflammatory response in patients operated with robot-assisted laparoscopy compared with conventional laparoscopy.

(författare) Acute suppurative thyroiditis with thyroid abscess in adults : clinical presentation, treatment and outcomes 2019 Ingår i: BMC Endocrine Disorders. - : BioMed Central (BMC). - 1472-6823. ; 19:1 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Abscess in the thyroid gland is a rare but severe infectious disease. The condition can have anatomic or iatrogenic underlying causes. If untreated it could be fatal. Pathogens vary considerably. Treatment is intravenous antibiotics, drainage, and sometimes surgery.METHODS: The electronic medical records of all adult patients with acute thyroiditis 2003-2017 treated at the Karolinska University Hospital (catchment area 2 million) in Sweden were systematically reviewed.RESULTS: Five patients were found in the catchment area. One patient from another region but known to us was also included. Thus, six patients (aged 28-73 years) were included in the study. Median length of hospital stay was 7.5 days (4-79 days). All were treated with antibiotics (intravenous n = 5, oral n = 1). Total antibiotic treatment duration was 13.5 days (10-41 days). Blood cultures were positive in three (streptococcus pneumonia, streptococci sanguineous, pepto streptococci), deep tissue culture in three (Escherichia coli, Candida, Hemophilic influenza) and no positive culture at all in two. Drainage was used in three patients. All patients recovered without recurrences. Surgery was performed twice in the acute phase in one. There was no recurrence during 7 years (3-12) of follow-up, but one patient died after three years (severe heart failure and pneumonia).CONCLUSION: Thyroid abscess in adults is extremely rare nowadays in the developed world. With prompt antibiotic therapy, drainage and in some cases thyroidectomy the prognosis seems favourable.

(författare) All-cause and cardiovascular mortality risk after surgery versus radioiodine treatment for hyperthyroidism 2018 Ingår i: British Journal of Surgery. - : John Wiley & Sons. - 0007-1323 .- 1365-2168. ; 105:3, s. 279-286 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Little is known about the long-term side-effects of different treatments for hyperthyroidism. The few studies previously published on the subject either included only women or focused mainly on cancer outcomes. This register study compared the impact of surgery versus radioiodine on all-cause and cause-specific mortality in a cohort of men and women.METHODS: Healthcare registers were used to find hyperthyroid patients over 35 years of age who were treated with radioiodine or surgery between 1976 and 2000. Comparisons between treatments were made to assess all-cause and cause-specific deaths to 2013. Three different statistical methods were applied: Cox regression, propensity score matching and inverse probability weighting.RESULTS: Of the 10 992 patients included, 10 250 had been treated with radioiodine (mean age 65·1 years; 8668 women, 84·6 per cent) and 742 had been treated surgically (mean age 44·1 years; 633 women, 85·3 per cent). Mean duration of follow-up varied between 16·3 and 22·3 years, depending on the statistical method used. All-cause mortality was significantly lower among surgically treated patients, with a hazard ratio of 0·82 in the regression analysis, 0·80 in propensity score matching and 0·85 in inverse probability weighting. This was due mainly to lower cardiovascular mortality in the surgical group. Men in particular seemed to benefit from surgery compared with radioiodine treatment.CONCLUSION: Compared with treatment with radioiodine, surgery for hyperthyroidism is associated with a lower risk of all-cause and cardiovascular mortality in the long term. This finding was more evident among men.

(författare) Increased Cardiovascular Mortality and Morbidity in Patients Treated for Toxic Nodular Goiter Compared to Graves' Disease and Nontoxic Goiter 2017 Ingår i: Thyroid. - : Mary Ann Liebert. - 1050-7256 .- 1557-9077. ; 27:7, s. 878-885 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Previous research has suggested an increased risk of death and cardiovascular disease in patients treated for hyperthyroidism. However, studies on this subject are heterogeneous, often based on old data, or have not considered the impact that treatment for hyperthyroidism might have on cardiovascular risk. It is also unclear whether long-term prognosis differs between Graves' disease and toxic nodular goiter. The aim of this study was to use a very large cohort built on recent data to assess whether improvements in cardiovascular care might have changed the prognosis over time. The study also investigated the impact of different etiologies of hyperthyroidism.METHODS: This was an observational register study for the period 1976-2012, with subjects followed for a median period of 18.4 years. Study patients were Stockholm residents treated for Graves' disease or toxic nodular goiter with either radioactive iodine or surgery (N = 12,239). This group was compared to Stockholm residents treated for nontoxic goiter (N = 3685), with adjustments made for age, sex, comorbidities, and time of treatment. Comparisons were also made to the general population of Stockholm. Outcomes were assessed in terms of all-cause and cardiovascular mortality as well as cardiovascular morbidity.RESULTS: The hazard ratios (HR) for all-cause mortality and for cardiovascular mortality were 1.27 [confidence interval (CI) 1.20-1.35] and 1.29 [CI 1.17-1.42], respectively, for hyperthyroid patients compared to those with nontoxic goiter. For cardiovascular morbidity, the HR was 1.12 [CI 1.06-1.18]. Patients aged ≥45 years who were treated for toxic nodular goiter were generally at greater risk than others, and those included from the year 1990 and onwards were at greater risk than those included earlier. Increased all-cause mortality, as well as cardiovascular mortality and morbidity, were also seen in comparisons with the general population.CONCLUSIONS: This is the first large study to indicate that the long-term risk of death and cardiovascular disease in hyperthyroid subjects is due to the hyperthyroidism itself and not an effect of confounding introduced by its treatment. Much of the excess risk is confined to individuals treated for toxic nodular goiter. Despite advances in cardiovascular care during recent decades, hyperthyroidism is still a diagnosis associated with increased cardiovascular morbidity and mortality.

(författare) Treatment outcome 6-10 years after diagnosis of hyperthyroidism in 2916 patients : a longitudinal evaluation of a swedish incidence cohort 2018 Ingår i: Thyroid. - : Mary Ann Liebert. - 1050-7256 .- 1557-9077. ; :S1 Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract Treatment of Graves’ disease (GD) and toxic nodular goiter (TNG) has the objectives to cure hyperthyroidism, prevent recurrent disease and preserve thyroid function. Treatment efficacies and long-termout comes of antithyroid drugs (ATD), radioactive iodine (RAI) or surgery varies in the literature. We report outcome of treatment, cure rate and risk factors for relapse for GD and TNG in an unselected cohort. A prospective incidence-cohort of de novo diagnosed GD and TNG patients (n = 2916) from 2003-05, were invited to a follow-up 6 - 10 years after diagnosis. Questionnaires were sent to 2430 patients regarding treatments, cure rate, recurrence, quality of life, demographic data, comorbidities and life-style factors. Patients were treated according to clinical routine with ATD, RAI or surgery. Of those included, 1186 (83.3%) had GD and 237 (16.7%) had TNG. In GD patients, 351 (45.3%), 264 (81.5%), and 52 (96.3%) were cured by ATD, RAI or surgery respectively as first line treatment. Of those, 77.0%, 15.4% and 3.8% respectively were without levothyr-oxine supplementation at follow-up at 8 – 0.9 years. Including all treatment modalities, 851 (71.8%) of GD patients were cured within one treatment period. At follow-up, 278 (23%) of GD patients had been operated. In TNG patients, RAI cured 88.6% and surgery 92.9%, whereof 52/154 (33.8%) and 3/15 (20%) had no levothyroxine supplementation post RAI and surgery, respectively.The proportion that did not feel fully recovered at follow-up was 25.3% of GD and 18.1% of the TNG patients. Overall, treatment of hyperthyroidism results in preserved thyroid function only in 35.3% and 44.7% of GD and TNG cases, respectively. As many as 23.4% of the GD patients end up with surgery although only 4.6% choose it from the beginning. Our treatment tradition cures 71.8% of GD patients and 78.1% of TNG patients within one treatment period. The high number of patients who do not feel recovered 6 -10 years after hyperthyroidism in GD and TNG is are minder of the chronic nature of hyperthyroidism.

The aim of this study was to determine the risk of malignancy (ROM) for each Bethesda category.METHODS: Thyroidectomy-related data from 314 facilities in 22 countries were entered into the following outcome registries: CESQIP (North America), Eurocrine (Europe), SQRTPA (Sweden) and UKRETS (UK). Demographic, cytological, pathologic and extent of surgery data were mapped into one dataset and analyzed.RESULTS: Out of 41,294 thyroidectomy patient entries from January 1, 2015, to June 30, 2017, 21,746 patients underwent both thyroid FNA and surgery. A comparison of cytology and surgical pathology data demonstrated a ROM for Bethesda categories 1 to 6 of 19.2%, 12.7%, 31.9%, 31.4%, 77.8% and 96.0%, respectively. Male patients had a higher rate of malignancy for every Bethesda category. Secondary analysis demonstrated a high ROM in male patients with Bethesda 3 category aged 31-35 years (52.1%, 95% confidence interval (CI) 37.9-66.2%), aged 36-40 years (55.9%, 95% CI 39.2-72.6%) and aged 41-45 years (46.9%, 95% CI 33-60.9%). Patients with Bethesda 5 and 6 scores were more likely to undergo total thyroidectomy (65.9% and 84.6%); for patients with Bethesda scores 2 and 3, a higher percentage of females underwent total thyroidectomy compared to males in spite of a higher ROM for males.CONCLUSIONS: These data demonstrate that Bethesda categories 1-4 are associated with a higher ROM compared to the first edition of TBSRTC, especially in male patients, and validate findings from the second edition of TBSRTC.

Reoperation was defined as repeat repair after primary repair.Results: Altogether 30,253 umbilical hernia repairs and 7407 epigastric hernia repairs were identified. There were 624 reoperations registered following primary umbilical repair and 137 following primary epigastric repairs. In multivariable Cox proportional hazard analysis, the hazard ratio (HR) for reoperation was 0.284 (95% confidence interval (CI) 0.106–0.760) after open onlay mesh repair, 0.476 (CI 0.359–0.629) after open interstitial mesh repair, 0.368 (CI 0.230–0.590) afteropen sublay mesh repair, 0.446 (CI 0.167–1.194) after open intraperitoneal onlay mesh repair, 0.931 (CI 0.639–1.357) after laparoscopic repair, and 0.939 (CI 0.502–1.757) after other (unknown) techniques, when compared to open suture repair as reference method. Following umbilical hernia repair, the risk for reoperation was also significantly higher for patients aged ≤49 years (HR 1.669, CI 1.391–2.002), for women (HR 1.390, CI 1.178–1.641), and for patients with liver cirrhosis (HR 2.546, CI 1.050–6.174). For patients undergoing epigastric hernia repair, the only significant risk factor for reoperation was age ≤49 years (HR 2.079, CI 1.380–3.134).Conclusions: All types of open mesh repair were associated with lower reoperation rates than open suture repair and laparoscopic repair. Female sex, young age and liver cirrhosis were risk factors for reoperation due to hernia recurrence, regardless of method.

(författare) Fracture Incidence in Graves' Disease: A Population-Based Study. 2023 Ingår i: Thyroid : official journal of the American Thyroid Association. - : Mary Ann Liebert. - 1557-9077 .- 1050-7256. ; 33:11, s. 1349-1357 Tidskriftsartikel (refereegranskat)abstract Background: Population-based studies have indicated an increase in bone turnover in hyperthyroidism with a subsequent decrease in bone mineral density and an increased risk of fractures, especially in postmenopausal women. However, heterogeneity between studies prevents a definitive conclusion. Graves' disease (GD) is an autoimmune disease, and it is the most common cause of hyperthyroidism. The aim of this study was to investigate fracture risk in patients with GD. Methods: A total of 2134 patients with incident GD and 21,261 age, sex- and county-matched controls were included 16-18 years after diagnosis in a retrospective cohort study. Drug and patient national registries in Sweden were used to assess the risk of developing skeletal complications. Up to 10 years of age, sex- and county-matched controls per patient were selected from databases from the National Board of Health and Welfare and Statistics Sweden. Cox proportional hazards models were fitted to estimate hazard ratios (HR) and confidence intervals [CI]. Results: There were no significant differences in fracture rates between GD and controls but after adjustment for comorbidities, the data showed higher vertebral fracture rates in male GD patients aged >52 years compared to male controls, HR=2.83 [CI 1.05-7.64]. The rates of osteoporosis treatments as well as treatment with corticosteroids were higher in patients with GD. However, HR for the association between GD and fractures remained largely unchanged after adjustment for osteoporosis treatments and treatments with corticosteroids. Conclusions: There were no significant differences in total fracture rate between GD and the general population. However, men older than 52 years had a higher vertebral fracture rate. This study also shows that patients with treated GD receive more osteoporosis treatments compared to the general population.

Karger AG. - 0028-3835 .- 1423-0194. ; 111:9, s. 840-849 Tidskriftsartikel (refereegranskat)abstract Background: Small intestinal neuroendocrine tumors (SI-NETs) are difficult to diagnose in the early stage of disease. Current blood biomarkers such as chromogranin A (CgA) and 5-hydroxyindolacetic acid have low sensitivity (SEN) and specificity (SPE). This is a first preplanned interim analysis (Nordic non-interventional, prospective, exploratory, EXPLAIN study [NCT02630654]). Its objective is to investigate if a plasma protein multi-biomarker strategy can improve diagnostic accuracy (ACC) in SI-NETs. Methods: At the time of diagnosis, before any disease-specific treatment was initiated, blood was collected from patients with advanced SI-NETs and 92 putative cancer-related plasma proteins from 135 patients were analyzed and compared with the results of age- and sex-matched controls (n = 143), using multiplex proximity extension assay and machine learning techniques. Results: Using a random forest model including 12 top ranked plasma proteins in patients with SI-NETs, the multi-biomarker strategy showed SEN and SPE of 89 and 91%, respectively, with negative predictive value (NPV) and positive predictive value (PPV) of 90 and 91%, respectively, to identify patients with regional or metastatic disease with an area under the receiver operator characteristic curve (AUROC) of 99%. In 30 patients with normal CgA concentrations, the model provided a diagnostic SPE of 98%, SEN of 56%, and NPV 90%, PPV of 90%, and AUROC 97%, regardless of proton pump inhibitor intake. Conclusion: This interim analysis demonstrates that a multi-biomarker/machine learning strategy improves diagnostic ACC of patients with SI-NET at the time of diagnosis, especially in patients with normal CgA levels. The results indicate that this multi-biomarker strategy can be useful for early detection of SI-NETs at presentation and conceivably detect recurrence after radical primary resection.

(författare) Pathogenesis and Clinical Management of Mesenteric Fibrosis in Small Intestinal Neuroendocine Neoplasms : A Systematic Review 2020 Ingår i: Journal of Clinical Medicine. - : MDPI. - 2077-0383. ; 9:6 Forskningsöversikt (refereegranskat)abstract Mesenteric fibrosis (MF) constitutes an underrecognized sequela in patients with small intestinal neuroendocrine neoplasms (SI-NENs), often complicating the disease clinical course. The aim of the present systematic review, carried out by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology, is to provide an update in evolving aspects of MF pathogenesis and its clinical management in SI-NENs. Complex and dynamic interactions are present in the microenvironment of tumor deposits in the mesentery. Serotonin, as well as the signaling pathways of certain growth factors play a pivotal, yet not fully elucidated role in the pathogenesis of MF. Clinically, MF often results in significant morbidity by causing either acute complications, such as intestinal obstruction and/or acute ischemia or more chronic conditions involving abdominal pain, venous stasis, malabsorption and malnutrition. Surgical resection in patients with locoregional disease only or symptomatic distant stage disease, as well as palliative minimally invasive interventions in advanced inoperable cases seem clinically meaningful, whereas currently available systemic and/or targeted treatments do not unequivocally affect the development of MF in SI-NENs. Increased awareness and improved understanding of the molecular pathogenesis of MF in SI-NENs may provide better diagnostic and predictive tools for its timely recognition and intervention and also facilitates the development of agents targeting MF.

Data was validated through scrutinizing FNAC and histology reports.RESULTS: Among the 2519 cases operated for TC, the diagnosis was substantiated and validated through the histology report in 2332 cases (92.6%). Among these, 1679 patients (72%) were female, and the median age at TC diagnosis was 52.3 years (range 18-94.6). Less than total thyroidectomy (LTT) was undertaken in 944 whereas total thyroidectomy (TT) in 1388 cases. The intermediate FNAC categories of atypia of undetermined significance/follicular lesion of undetermined significance (AUS/ FLUS), as well as suspicion for follicular neoplasm (SFN) lesions were more often encountered in LTT (n = 314, 33.3%) than TT (n = 63, 4.6%), whereas FNACs suspicion for malignancy and/or malignancy were overrepresented in TT (n = 963, 69.4%). Completion thyroidectomies were undertaken in 553 patients out of 944 that initially had LTT. In 201 cases with cancer lesions > 1 cm, other than FTC (Follicular TC)/ HTC (Hürthle cell TC) subjected to primary LTT, inadequate procedures were undertaken in 81 due to absent, Bethesda I or II FNAC categories, preoperatively. Complications at completion of surgery in this particular setting were 0.5% for RLN palsy (n = 1) and 1% (n = 2) for hypoparathyroidism 6 months postoperatively. The overall postoperative complication rate was higher in primary TT vs. LTT for RLN palsy (4.8% [n = 67] vs. 2.4% [n = 23]; p = 0.003) and permanent hypoparathyroidism (6.8% [n = 95] vs. 0.8% [n = 8]; p < 0.0001).CONCLUSIONS: FNAC results appear to affect surgical planning in TC as intermediate FNAC categories lead more often to LTT. Overall, inadequate procedures necessitating completion surgery are encountered in up to 15% of TC patients subjected to LTT due to absent, inconclusive, or misleading FNAC, preoperatively. However, completion of thyroidectomy in this setting did not yield significant surgical morbidity. Primary LTT is a safer primary approach compared to TT in respect of RLN palsy and permanent hypoparathyroidism complication rates; therefore, primary TT should probably be reserved for lesions > 1 cm or even larger with suspicion for malignancy or malignant FNAC.

Karger. - 2235-0640 .- 2235-0802. ; 10:3, s. 185-197 Tidskriftsartikel (refereegranskat)abstract The growing detection of papillary thyroid microcarcinomas (PTMCs) is paralleled by an increase in surgical procedures. Due to the frequent indolent nature, cost, and risk of surgery, active surveillance (AS) and ultrasound-guided minimally invasive treatments (MITs) are in suitable cases of incidental PTMC proposed as alternatives to thyroidectomy. Surgery and radioiodine are the established treatments for relapsing cervical differentiated thyroid carcinoma (DTC) metastases. But radioiodine refractoriness, risk of surgical complications, adverse influence on quality of life, or declining repeat surgery have led to AS and MIT being considered as alternatives for slow-growing DTC nodal metastases. Also, for distant radioiodine-refractory metastases not amenable to surgery, MIT is proposed as part of a multimodality therapeutic approach. The European Thyroid Association and the Cardiovascular and Interventional Radiological Society of Europe commissioned these guidelines for the appropriate use of MIT. Based on a systematic PubMed search, an evidence-based approach was applied, and both knowledge and practical experience of the panelists were incorporated to develop the manuscript and the specific recommendations. We recommend that when weighing between surgery, radioiodine, AS, or MIT for DTC, a multidisciplinary team including members with expertise in interventional radiology assess the demographic, clinical, histological, and imaging characteristics for appropriate selection of patients eligible for MIT. Consider TA in low-risk PTMC patients who are at surgical risk, have short life expectancy, relevant comorbidities, or are unwilling to undergo surgery or AS. As laser ablation, radiofrequency ablation, and microwave ablation are similarly safe and effective thermal ablation (TA) techniques, the choice should be based on the specific competences and resources of the centers. Use of ethanol ablation and high-intensity focused ultrasound is not recommended for PTMC treatment. Consider MIT as an alternative to surgical neck dissection in patients with radioiodine refractory cervical recurrences who are at surgical risk or decline further surgery. Factors that favor MIT are previous neck dissection, presence of surgical complications, small size metastases, and <4 involved latero-cervical lymph nodes. Consider TA among treatment options in patients with unresectable oligometastatic or oligoprogressive distant metastases to achieve local tumor control or pain palliation. Consider TA, in combination with bone consolidation and external beam radiation therapy, as a treatment option for painful bone metastases not amenable to other established treatments.

(författare) Characterization of Calcium Homeostasis in Lithium-Treated Patients Reveals Both Hypercalcaemia and Hypocalcaemia 2020 Ingår i: World Journal of Surgery. - : Springer. - 0364-2313 .- 1432-2323. ; 44:2, s. 517-525 Tidskriftsartikel (refereegranskat)abstract INTRODUCTION: Prevalence studies demonstrate that a significant proportion of lithium-treated patients develop hypercalcaemia (3-30%). Lithium-associated hyperparathyroidism (LHPT) is poorly defined, and calcium homeostasis may be affected in a more complicated fashion than purely by elevated PTH secretion. The current study aims to examine in detail calcium homeostasis principally with regard to lithium duration.METHODS: Medical records of 297 lithium-treated patients (193 women, 104 men; median age 58 years) were examined, and information on gender, age, lithium treatment duration and calcium homeostasis was obtained. The median treatment duration with lithium was 16 (1.5-45) years.RESULTS: A total of 8504 calcium values were retrieved. Before initiation of lithium treatment, serum calcium was on average 2.33 mmol/l (2.02-2.60). During the treatment period, 178 patients (60%) remained normocalcaemic, 102 (34%) developed hypercalcaemia or were strongly suspected of LHPT, 17 (6%) had 3 or more intermittent episodes of hypocalcaemia. Forty-one per cent of patients with suspected or confirmed LHPT had low (<4 mmol) 24-h urine calcium levels. The success rate after 33 parathyroidectomies was 35%, hyperplasia being diagnosed in 75% of extirpated glands.CONCLUSIONS: The prevalence of hypercalcaemia during lithium treatment is very high. In addition, hypocalcaemic episodes appear to occur frequently, possibly reflecting a more complicated parathyroid dysfunction than previously known. Long-term surgical results are unsatisfactory. LHPT biochemical profile is different from that of primary hyperparathyroidism and is in some ways similar to familial hypocalciuric hypercalcaemia.

The aim of the present study was to determine the prevalence of hypercalcemia in a cohort of bipolar patients (BP) with and without concomitant lithium treatment and to study surgical outcomes for lithium-associated hyperparathyroidism. Methods Retrospective data, including laboratory results, surgical outcomes and medications, were collected from 313 BP treated with lithium from two psychiatric outpatient units in central Sweden. In addition, data were collected from 148 BP without lithium and a randomly selected control population of 102 individuals. Logistic regression was used to compare odds of hypercalcemia in these respective populations. Results The prevalence of lithium-associated hypercalcemia was 26%. Mild hypercalcemia was detected in 87 out of 563 study participants. The odds of hypercalcemia were significantly higher in BP with lithium treatment compared with BP unexposed to lithium (adjusted OR 13.45; 95% CI 3.09, 58.55; p = 0.001). No significant difference was detected between BP without lithium and control population (adjusted OR 2.40; 95% CI 0.38, 15.41; p = 0.355). Seven BP with lithium underwent surgery where an average of two parathyroid glands was removed. Parathyroid hyperplasia was present in four patients (57%) at the initial operation. One patient had persistent disease after the initial operation, and six patients had recurrent disease at follow-up time which was on average 10 years. Conclusion The high prevalence of LAH justifies the regular monitoring of calcium homeostasis, particularly in high-risk groups. If surgery is necessary, bilateral neck exploration should be considered in patients on chronic lithium treatment. Prospective studies are needed.

33.	Meehan, Adrian, 1973- (författare) Lithium-associated hyperparathyroidism : Prevalence, Pathophysiology, Management 2018 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract Lithium has been used in the treatment of bipolar disorder, formerly called manic depression, for nearly seven decades. Lithium-associated hyperparathyroidism (LHPT) is an ill-defined and less well known possible side-effect of chronic lithium therapy and was first described in 1973. The condition has been considered to be rare, though there exists conflicting evidence as to its prevalence, its pathophysiological background, and, if and when identified, what the appropriate medical or surgical treatment should be. The principal aim of this thesis was to understand and more comprehensively characterise this condition through studying a large patient cohort, with regards its prevalence, development, and additionally by providing an evaluation of surgical management up until now.In Study I a population of 423 lithium-treated out-patients (251 women, 172 men) were recruited from Jönköping and Örebro County. We found that 18% met the criteria for hyperparathyroidism (HPT) and that a further 21% had intermittent episodes of hypercalcaemia. We then examined, in Study II, the effects of lithium only in patients with bipolar disorder and compared them, firstly, to patients with bipolar disorder without lithium and, secondly, to a control population. In total, 563 individuals participated in the study. Hypercalcaemia was found to be strongly associated to lithium therapy (adjusted OR 13.45; 95% CI 3.09, 58.55; p=0.001). Study III is a descriptive study of calcium homeostasis in 297 lithium-treated patients from Jönköping where three main groups could be discerned: 178 were normocalcaemic (60%), 102 hypercalcaemic (34%), and 17 hypocalcaemic (6%). Many patients demonstrate robust fluctuations in serum calcium intermittently. Of those with suspected LHPT, 31% had urinary calcium excretion values be-low 1.2 mmol/24hrs. Study IV analysed surgical results of 78 parathyroidectomies in 71 patients with concurrent lithium therapy. In strong contrast to surgical outcomes in those with primary HPT, the overall cure-rate was lower (58%) and the predominant histological diagnosis was hyperplasia (52%). Two patients had double adenomas.Factors which should be particularly taken into consideration while monitoring lithium-treated patients are age, gender and lithium-duration.

We hypothesized that β-blockade before TBI is associated with improved survival.Methods: The trauma registry of an urban academic trauma center was queried to identify patients with an isolated severe TBI between January 2007 and December 2011. Isolated severe TBI was defined as an intracranial injury with an Abbreviated Injury Scale (AIS) score of 3 or greater excluding all extracranial injuries AIS score of 3 or greater. Patient demographics, clinical characteristics on admission, injury profile, Injury Severity Score (ISS), AIS score, in-hospital morbidity, and β-blocker exposure were abstracted for analysis. The primary outcome evaluated was in-hospital mortality stratified by preinjury β-blockade exposure.Results: Overall, a total of 662 patients met the study criteria. Of these, 25% (n = 159) were exposed to β-blockade before their traumatic insult. When comparing the demographics and injury characteristics between the groups, the sole difference was age, with the β-blocked group being older (69 [12] years vs. 63 [13] years, p < 0.001). β-blocked patients had a higher rate of infectious complications (30% vs. 19%, p = 0.04), with no difference in cardiac or pulmonary complications between the cohorts. Patients exposed to β-blockade versus no β-blockade experienced 13% and 22% mortality, respectively (p = 0.01). Stepwise logistic regression predicted the absence of β-blockade exposure as a risk factor for mortality (odds ratio, 2.7; 95% confidence interval, 1.5-4.8; p = 0.002). After adjustment for significant differences between the groups, patients not exposed to β-blockade experienced twofold increased risk of mortality (adjusted odds ratio, 2.2; 95% confidence interval, 1.3-3.7; p = 0.004).Conclusion: Preinjury β-blockade improves survival following isolated severe TBI. The role of prophylactic β-blockade and the timing of initiation of such therapy after TBI warrant further investigations.Level of evidence: Therapeutic study, level III; prognostic study, level II.

The purpose of this study was to evaluate the effect of beta-blockade on mortality in a Swedish cohort of isolated severe TBI patients.The trauma registry of an urban academic trauma center was queried to identify patients with an isolated severe TBI between 1/2007 and 12/2011. Isolated severe TBI was defined as an intracranial injury with an Abbreviated Injury Scale (AIS) a parts per thousand yen3 excluding extra-cranial injuries AIS a parts per thousand yen3. Multivariable logistic regression analysis was used to determine the effect of beta-blocker exposure on mortality. Also, a subgroup analysis was performed to investigate the risk of mortality in patients on pre-admission beta-blocker versus not and the effect of specific type of beta-blocker on the overall outcome.Overall, 874 patients met the study criteria. Of these, 33 % (n = 287) were exposed to beta-blockers during their hospital admission. The exposed patients were older (62 +/- A 16 years vs. 49 +/- A 21 years, p < 0.001), and more severely injured based on their admission GCS, ISS, and head AIS scores (GCS a parts per thousand currency sign8: 32 % vs. 28 %, p = 0.007; ISS a parts per thousand yen16: 71 % vs. 59 %, p = 0.001; head AIS a parts per thousand yen4: 60 % vs. 45 %, p < 0.001). The crude mortality was higher in patients who did not receive beta-blockers (17 % vs. 11 %, p = 0.007) during their admission. After adjustment for significant confounders, the patients not exposed to beta-blockers had a 5-fold increased risk of in-hospital mortality (AOR 5.0, CI 95 % 2.7-8.5, p = 0.001). No difference in survival was noted in regards to the type of beta-blocker used. Subgroup analysis revealed a higher risk of mortality in patients naive to beta-blockers compared to those on pre-admission beta-blocker therapy (AOR 3.0 CI 95 % 1.2-7.1, p = 0.015).Beta-blocker exposure after isolated severe traumatic brain injury is associated with significantly improved survival. We also noted decreased mortality in patients on pre-admission beta-blocker therapy compared to patients naive to such treatment. Further prospective studies are warranted.

We analysed timing and variation in moose (Alces alces) parturition dates of 555 females at 18 study sites across 12 degrees of latitude (56-68 degrees N, 1350 km) in Sweden. We found evidence for a spatial match of parturition timing to vegetation onset, but no evidence that moose adjust parturition to vegetation onset in a given year. We found a breakpoint at 64 degrees N. Despite adaptation across latitudes, temporal divergences occurred. Females below 64 degrees N calved after vegetation onset and females above 64 degrees N calved before. Here, parturition before vegetation onset might be a strategy to optimize forage utilization time with the very short growing season. Highly seasonal environments such as at higher latitudes may make it advantageous to adapt parturition towards long-term climatic patterns by matching the most favourable period. Given the direction of temporal divergence, our study suggests that climate change may have less of an impact on moose parturition at northern latitudes than southern latitudes.

Physiological studies are difficult to perform in patients suffering from life-threatening conditions such as rAAA. A translational model of the condition is therefore needed. The aim was to develop and validate an endovascular animal model for retroperitoneal bleeding of the abdominal aorta with contained hematoma.METHODS: = 6). Onset of bleeding was verified by angiography and macroscopically examined on completion of the experiments. Survival up to 180 min was the primary outcome. Hemodynamic and metabolic markers in arterial blood were secondary outcomes.RESULTS: = 0.002), but not when comparing the 6 mm and 8 mm groups. Systemic hypotension, arterial acidosis, and lactatemia were provoked in the 6 mm and 8 mm groups but not in the 4 mm group.CONCLUSIONS: A porcine model for a controlled contained left posterolateral retroperitoneal bleeding was created using endovascular methods and validated. This model makes it possible to study the pathophysiology of a retroperitoneal hematoma.

(författare) The Long-Term Outcome of Treatment for Graves' Hyperthyroidism 2019 Ingår i: Thyroid. - : Mary Ann Liebert Inc. - 1050-7256 .- 1557-9077. ; 29:11, s. 1545-1557 Tidskriftsartikel (refereegranskat)abstract Background: The treatment efficacy of antithyroid drug (ATD) therapy, radioactive iodine (I-131), or surgery for Graves' hyperthyroidism is well described. However, there are a few reports on the long-term total outcome of each treatment modality regarding how many require levothyroxine supplementation, the need of thyroid ablation, or the individual patient's estimation of their recovery. Methods: We conducted a pragmatic trial to determine the effectiveness and adverse outcome in a patient cohort newly diagnosed with Graves' hyperthyroidism between 2003 and 2005 (n = 2430). The patients were invited to participate in a longitudinal study spanning 8 +/- 0.9 years (mean +/- standard deviation) after diagnosis. We were able to follow 1186 (60%) patients who had been treated with ATD, I-131, or surgery. We determined the mode of treatment, remission rate, recurrence, quality of life, demographic data, comorbidities, and lifestyle factors through questionnaires and a review of the individual's medical history records. Results: At follow-up, the remission rate after first-line treatment choice with ATD was 45.3% (351/774), with I-131 therapy 81.5% (324/264), and with surgery 96.3% (52/54). Among those patients who had a second course of ATD, 29.4% achieved remission (vs. the 45.3% after the first course of ATD). The total number of patients who had undergone ablative treatment was 64.3% (763/1186), of whom 23% (278/1186) had received surgery, 43% (505/1186) had received I-131 therapy, including 2% (20/1186) who had received both surgery and I-131. Patients who received ATD as first-line treatment and possibly additional ATD had 49.7% risk (385/774) of having undergone ablative treatment at follow-up. Levothyroxine replacement was needed in 23% (81/351) of the initially ATD treated in remission, in 77.3% (204/264) of the I-131 treated, and in 96.2% (50/52) of the surgically treated patients. Taken together after 6-10 years, and all treatment considered, normal thyroid hormone status without thyroxine supplementation was only achieved in 35.7% (423/1186) of all patients and in only 40.3% of those initially treated with ATD. The proportion of patients that did not feel fully recovered at follow-up was 25.3%. Conclusion: A patient selecting ATD therapy as the initial approach in the treatment of Graves' hyperthyroidism should be informed that they have only a 50.3% chance of ultimately avoiding ablative treatment and only a 40% chance of eventually being euthyroid without thyroid medication. Surprisingly, 1 in 4 patients did not feel fully recovered after 6-10 years. The treatment for Graves' hyperthyroidism, thus, has unexpected long-term consequences for many patients.
39.	Sjölin, Gabriel, 1979- (författare) Hyperthyroidism : a chronic disease? 2021 Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract During 2003-2005, approximately 3,000 de novo hyperthyroid patients were collected in Sweden and became one of the world's largest hyperthyroidism studies. This dissertation shows that many people diagnosed with hyperthyroidism live with its impacts even after excess of thyroid hormone has ended. These include repeated recurrences, multiple treatments, replacement therapy, little sense of recovery, and reduced Quality Of life(QoL). Patients were categorised into two groups, Graves' disease (GD) and toxic nodular goitre (TNG), studied separately. Overall, just over 1,400 patients, or 60% of dispatches, answered the questionnaires. 1186 GD, 237 TNG. Most patients were women and GD's mean age was around 40 years, while TNG patients were 20 years older, reflecting the same patternas previous studies. The incidence of 27/100,000 persons per year might not seem large, but considering the proposed chronic nature of hyperthyroidism, prevalence is high (0.7%). Around two in three people diagnosed with hyperthyroidism will live with thyroid hormone replacement. This could be attributed, that GD patients over time receive more ablative treatment, despite the fact that less receive it as the first treatment. Another explanation the recurrence risk of ATD-treated patients exceeds 50%. Levothyroxine treatment did not vary between TNG treatments. Repeated, often multiple, treatments in TNG patients are rarely described. This implies TNG may be more complex than anticipated. Hyperthyroid patients have worse QoL 6-10 years following diagnosis than the general public. RAI treated patients with GD had more affected long-term thyroid-specific and generic QoL than ATD and surgical patients. Surprisingly, there was no clear QoL difference between GD and TNG. GD is often seen as a severe condition than TNG, as TNG has a milder course of disease. Hyperthyroidism has long-term impacts, affecting a relatively large population. This dissertation's findings indicate a chronic nature of hyperthyroidism.

(författare) Long term outcome after toxic nodular goitre 2022 Ingår i: Thyroid Research. - : Springer Science and Business Media LLC. - 1756-6614. ; 15:1 Tidskriftsartikel (refereegranskat)abstract Background: The purpose of treating toxic nodular goitre (TNG) is to reverse hyperthyroidism, prevent recurrent disease, relieve symptoms and preserve thyroid function. Treatment efficacies and long-term outcomes of antithyroid drugs (ATD), radioactive iodine (RAI) or surgery vary in the literature. Symptoms often persist for a long time following euthyroidism, and previous studies have demonstrated long-term cognitive and quality of life (QoL) impairments. We report the outcome of treatment, rate of cure (euthyroidism and hypothyroidism), and QoL in an unselected TNG cohort. Methods: TNG patients (n = 638) de novo diagnosed between 2003-2005 were invited to engage in a 6-10-year follow-up study. 237 patients responded to questionnaires about therapies, demographics, comorbidities, and quality of life (ThyPRO). Patients received ATD, RAI, or surgery according clinical guidelines. Results: The fraction of patients cured with one RAI treatment was 89%, and 93% in patients treated with surgery. The rate of levothyroxine supplementation for RAI and surgery, at the end of the study period, was 58% respectively 64%. Approximately 5% of the patients needed three or more RAI treatments to be cured. The patients had worse thyroid-related QoL scores, in a broad spectrum, than the general population. Conclusion: One advantage of treating TNG with RAI over surgery might be lost due to the seemingly similar incidence of hypothyroidism. The need for up to five treatments is rarely described and indicates that the treatment of TNG can be more complex than expected. This circumstance and the long-term QoL impairments are reminders of the chronic nature of hyperthyroidism from TNG.

We aimed to evaluate the effect of palliative primary tumor resection (PPTR) on overall survival (OS) in this setting. We searched the MEDLINE, Embase, Cochrane Library, Web of Science and SCOPUS databases up to January 2020 and used the Newcastle-Ottawa scale (NOS) criteria to assess quality/risk of bias. A total of 5661 articles were screened. In 10 studies, 5551 unique patients with stage IV PanNEN and unresectable metastases were included. The five-year OS for PanNEN patients undergoing PPTR in stage IV was 56.6% vs. 23.9% in the non-surgically treated patients (random effects relative risk (RR): 1.70; 95% CI: 1.53-1.89). Adjusted analysis of pooled hazard ratios (HR) confirmed longer OS in PanNEN patients undergoing PPTR (random effects HR: 2.67; 95% CI: 2.24-3.18). Cumulative OS analysis confirmed an attenuated survival benefit over time. The complication rate of PPTR was as high as 27%. In conclusion, PPTR may exert a survival benefit in stage IV PanNEN. However, the included studies were subject to selection bias, and special consideration should be given to PPTR anchored to a multimodal treatment strategy. Further longitudinal studies are warranted, with long-term follow-up addressing the survival outcomes associated with surgery in stage IV disease.

(författare) Impaired Quality of Life After Radioiodine Therapy Compared to Antithyroid Drugs or Surgical Treatment for Graves’ Hyperthyroidism : A Long-Term Follow-Up with the Thyroid-Related Patient-Reported Outcome Questionnaire and 36-Item Short Form Health Status Survey 2019 Ingår i: Thyroid. - : Mary Ann Liebert. - 1050-7256 .- 1557-9077. ; 29:3, s. 322-331 Tidskriftsartikel (refereegranskat)abstract BACKGROUND: Hyperthyroidism is known to have a significant impact on the quality of life (QoL) at least in the short term. The purpose of the present study was to assess QoL in patients at 6-10 years after treatment for Graves' disease (GD) with radioiodine (RAI) to those treated with thyroidectomy or antithyroid drugs (ATD) as assessed with both a thyroid-specific (ThyPRO) and general (SF-36) QoL surveys.METHODS: We evaluated 1186 GD patients in a sub-cohort from an incidence study 2003-2005 which had been treated according to routine clinical practice at seven participating centers. Patients were included if they had returned the ThyPRO (n=975) and/or the SF-36 questionnaire (n=964) and informed consent at follow-up. Scores from ThyPRO were compared with scores from a general population sample (n=712), using multiple linear regression adjusting for age and gender as well as multiple testing. Treatment related QoL outcome for ATD, RAI and surgery were compared including adjustment for the number of treatments received, sex, age and co-morbidity.RESULTS: Regardless of treatment modality, patients with GD had worse thyroid-related QoL 6-10 years after diagnosis compared with the general population. Patients treated with RAI had worse thyroid-related and general QoL than patients treated with ATD or thyroidectomy on the majority of QoL-scales. Sensitivity analyses supported the relative negative comparative effects of RAI treatment on QoL in patients with hyperthyroidism.CONCLUSIONS: Graves' disease is associated with a lower QoL many years after treatment compared to the general population. In a previous, small RCT we did not show any difference in patient satisfaction years after ATD, RAI or surgery. We now report that in a large non-randomized cohort, patients who received RAI had adverse scores on ThyPRO and SF-36. These findings in a Swedish population are limited by comparison to normative data from Denmark, by older age and possibly a more prolonged course in those patients who received radioiodine, and a lack of information regarding thyroid status at the time of evaluation. The way RAI may adversely affect QoL is unknown but since the results may be important for future considerations regarding treatment options for GD they need to be substantiated in further studies.

Data on prevalence, prognostic significance, and clinical course of disease for SI-NET patients with VM is limited. In this retrospective analysis of 230 SI-NET patients treated at two tertiary referral centers, we found nine patients with VM (prevalence 3.9%). Among those, there were 5 females and median age at SI-NET and VM diagnosis was 61 and 65 years, respectively. Two patients had G1 tumors and five G2, while two tumors were of unspecified grade (median Ki67: 7%, range 2-15%). Four patients presented with synchronous VM, whereas five developed metachronous VM after a median of twenty-four months (range: 4.8-117.6 months). Hepatic metastases were present in seven patients, extrahepatic metastases (EM) in eight (six para-aortic distant lymph node metastases, one lung and one pancreatic metastasis), whereas peritoneal carcinomatosis (PC) in two patients. We used a control group of 18 age- and sex-matched SI-NET patients from the same cohort with stage IV disease but no extra-abdominal metastases. There was no difference in best-recorded response to first line treatment according to RECIST 1.1 as well as progression-free survival (PFS) between patients with VM and those in the control group (Chi-square test p = 0.516; PFS 71.7 vs. 106.9 months [95% CI 38.1-175.8]; log-rank p = 0.855). In addition, median overall survival (OS) of SI-NET patients with VM did not differ from those in the control group (138.6 [95% CI 17.2-260] vs. 109.9 [95% CI 91.7-128] months; log-rank p = 0.533). In conclusion, VM, although relatively rare in patients with SI-NETs, is more often encountered in patients with G2 tumors and established distant para-aortic lymph node metastases. The presence of VM in SI-NET patients does not seem to impact patients' survival outcomes and treatment responses, when compared to age- and sex-matched SI-NET patients with stage IV disease confined in the abdomen.

Our aim was to determine the prevalence of extra-abdominal metastases on 68Ga-DOTATOC-PET/CT in a cohort of patients with small intestinal (Si-NET) and pancreatic NET (Pan-NET), as well as that of pancreatic metastasis in patients with Si-NET. Among 2090 patients examined by 68Ga-DOTATOC-PET/CT at two tertiary referral centres, a total of 1177 patients with a history of Si- or Pan-NET, were identified. The most recent 68Ga-DOTATOC-PET/CT report for each patient was reviewed, and the location and number of metastases of interest were recorded. Lesions outside the liver and abdominal nodes were found in 26% of patients (n = 310/1177), of whom 21.5% (255/1177) were diagnosed with Si-NET and 4.5% (55/1177) Pan-NET. Bone metastases were found in 18.4% (215/1177), metastases to Virchow's lymph node in 7.1% (83/1177), and lung/pleura in 4.8% (56/1177). In the subset of 255 Si-NET patients, 5.4% (41/255) manifested lesions in the pancreas, 1.5% in the breast (18/255), 1.3% in the heart (15/255) and 1% in the orbita (12/255). In Si-NET patients, the Ki-67 proliferation index was higher in those with ≥2 metastatic sites of interest, than with 1 metastatic site, (p <0.001). Overall, extra-abdominal or pancreatic metastases were more often found in patients with Si-NET (34%) than in those with Pan-NET (13%) (p <0.001). Bone metastases were 2.6 times more frequent in patients with Si-NET compared to Pan-NET patients (p <0.001). Lesions to the breast and orbita were encountered in almost only Si-NET patients. In conclusion, lesions outside the liver and abdominal nodes were detected in as many as 26% of the patients, with different prevalence and metastatic patterns in patients with Si-NET compared to Pan-NET. The impact of such metastases on overall survival and clinical decision-making needs further evaluation.

Further analysis did not reveal any correlation between RECIST 1.1 responses and >25% changes in serum 5HIAA levels (Fisher ́s exact test p=0.735). The concordance rate of serum and urinary 5HIAA positivity at standardized laboratory cut-offs was 75%. In patients without any impairment of the renal function, the concordance between the two tests was as high as 89% and a sensitivity and specificity of 80% and 88.9%, respectively was evident (Cohen’s kappa coefficient=0.685).Conclusion: Serum 5HIAA performs well compared to urinary testing for diagnostic purposes and corresponds well to tumor stage and liver tumor burden. However, it is not adequate to predict tumor progression.

Median Ki-67 was 7% (1-70); 106 were G1 tumors, 142 G2, 11 G3 and 51 of unknown grade. Rare metastatic sites were present in bone 18 % (215/1171), Virchow's lymph node 6 % (75/1171) and 4 % (42/1171) in the lung/pleura. Metastases to the pancreas, breast, heart and orbita were only encountered in SI-NET primaries with a frequency of 5 % (41/753), 2 % (17/753), 2 % (14/753) and 2 % (12/753) respectively. Concomitant liver metastases were present in 86 %. Uncommon metastases were more frequent in SI-NET as compared with P-NET primaries, 255/753 [34%] vs. 55/418 [13%], p ˂0.00001. Bone metastases were present in 23 % (175/753) of SI-NET and 10 % (40/418) of p-NET primaries.Conclusion: In conclusion, rare metastases are more frequent in SI-NET than p-NETs. The variety and pattern of rare metastases seems different between SI-NETs and P-NET primaries, as orbita, heart, breast and Virchow's lymph node deposits were only encountered in SI-NETs patients; and bone metastases were approximately twice more often inthis group.
