- There is limited data on long-term outcomes after hospitalization for ACS. We aimed to estimate the rate of recurrent cardiovascular events in the long-term, in a population-based, unselected cohort of ACS patients. We included 1379 patients with ACS hospitalized at Östersund hospital 2010–2014 and followed them from the day after discharge to 31 December 2017. The primary endpoint was the unadjusted rate of the composite of CV death, AMI and ischemic stroke. Risk factors for the primary endpoint were assessed in a multivariable Cox proportional hazards regression model. During a median follow-up of 4.7 years, the unadjusted rate of the primary endpoint was 10.3% at 1 year and 28.6% at the end of follow-up. Predictors of increased risk for subsequent events were congestive heart failure, diabetes mellitus, angina pectoris, prior revascularization with PCI or CABG and treatment with diuretics at discharge. Lipid-lowering therapy at discharge and revascularization with PCI or CABG were associated with a lower risk of recurrent events. The risk of recurrent cardiovascular was high at 1 year and continued to be so during the following almost 3 years of median follow-up. Established predictors of cardiovascular risk were confirmed.

- Purpose: Exposure to cold air may harm the airways. It is unclear to what extent heavy exercise adds to the cold-induced effects on peripheral airways, airway epithelium, and systemic immunity among healthy individuals. We investigated acute effects of heavy exercise in sub-zero temperatures on the healthy airways.Methods: Twenty-nine healthy individuals underwent whole body exposures to cold air in an environmental chamber at − 15 °C for 50 min on two occasions; a 35-min exercise protocol consisting of a 5-min warm-up followed by 2 × 15 min of running at 85% of VO2max vs. 50 min at rest. Lung function was measured by impulse oscillometry (IOS) and spirometry before and immediately after exposures. CC16 in plasma and urine, and cytokines in plasma were measured before and 60 min after exposures. Symptoms were surveyed pre-, during and post-trials.Results: FEV1 decreased after rest (− 0.10 ± 0.03 L, p < 0.001) and after exercise (− 0.06 ± 0.02 L, p = 0.012), with no difference between trials. Exercise in − 15 °C induced greater increases in lung reactance (X5; p = 0.023), plasma CC16 (p < 0.001) as well as plasma IL-8 (p < 0.001), compared to rest. Exercise induced more intense symptoms from the lower airways, whereas rest gave rise to more general symptoms.Conclusion: Heavy exercise during cold air exposure at − 15 °C induced signs of an airway constriction to a similar extent as rest in the same environment. However, biochemical signs of airway epithelial stress, cytokine responses, and symptoms from the lower airways were more pronounced after the exercise trial.

- Introduction: Rates of cesarean section are rising in both developed and developing countries and while pregnancy and cesarean section are established as risk factors for thromboembolism and stroke, large population-based investigations focusing on all types of cardiovascular complication after delivery is missing. The aim was to analyze the risk of severe cardiovascular complications in the post-partum period following delivery by cesarean section. We also had a control group of vaginal deliveries and a reference group with nulliparas.Materials and Methods: This Swedish population-based study used three national registers between 2005 and 2017 and comprised a total of 1 165 684 individuals. Unselected register data was cross-linked and cardiovascular adverse events were identified by ICD diagnosis codes. 140 128 women (209 391 deliveries) were included in the cesarean group and 614 355 women (973 429 deliveries) in the vaginal control group. The reference group comprised 411 201 age-matched nulliparous women. The primary analysis was the risk of severe cardiovascular complications within 42 days of cesarean section or vaginal delivery. The secondary analysis evaluated risk factors for cardiovascular complications.Results: In the cesarean section group, 410 (0.20%) had a serious cardiovascular event within 42 days after delivery, and in the vaginal control group the number was 857 (0.09%). The risk of having an adverse cardiovascular event was significantly greater in the cesarean group (OR 2.23, CI 1.98 to 2.51) for all types of cardiovascular events. Risk factors were high BMI, preeclampsia, greater maternal age, tobacco use and acute cesarean delivery.Conclusions: The absolute numbers on severe maternal morbidity after delivery are low. However, since almost half of the world’s population are affected and the frequency of elective cesarean section continues to rise, a doubling of the risk for a severe cardiovascular event within 42 days of delivery is important to consider globally.

- Background: Pelvic floor muscle training (PFMT) is first-line treatment for urinary incontinence (UI) in women. Self-management via a mobile app is a new cost-effective method for PFMT delivery. This study analyzes factors associated with improvement among app users.Methods: A pragmatic observational study in a community setting. Upon downloading the app Tät®, users answered questions regarding their age, education, residence, and UI symptoms. After 3 months, users answered follow-up questions regarding symptoms and frequency of training and app usage, and the validated Patient Global Impression of Improvement (PGI-I) questionnaire. Only non-pregnant, non-postpartum adult women with UI who answered the PGI-I questionnaire were included. Multivariate logistic regression was used to analyze possible associations between these factors with any improvement and with great improvement according to the PGI-I. The models were adjusted for age.Results: The study included 2,153 participants who had completed self-management, that is, 11.5% of eligible women who completed the baseline questionnaire. Of these participants, 65.6% reported improvement of UI. Any improvement was associated with age, frequency of PFMT, and app use, accounting for 27.9% of variability (Nagelkerke R2). Lower incontinence severity, frequency of PFMT, and app use were associated with great improvement.Conclusion: Self-management of urinary incontinence is easily accessible to many women and improvement rates are comparable with other forms of PFMT. Demographic factors and incontinence severity showed no or incongruent association, whereas regular PFMT and app use predicted any and great improvement. App use showed an additional effect beyond frequency of training.

- This study aims to evaluate an intervention, consisting of nine weeks of health-management course, combined with social and working life orientation and language instruction for recently settled immigrants in Sweden. One hundred one participants in the intervention groups and 48 participants in the control group participated. The intervention consisted of a health management course combined with social and working life orientation and the control group participated in the regular local authority program for social and working life orientation. Measurement instruments were health-related quality of life (HRQoL) and registration of work rate. Several participants in the groups were in work, primarily in subsidized employment, after six months. Recently settled men were employed to a greater extent than the women, where poorer physical and mental health could be observed among women in this study. Participants in the intervention and the control groups had maintained HRQoL from pre-intervention to six months post-intervention. More studies investigating the participants experiences of the health-managing course but also more homogenous measurements in studies for recently settled immigrants are needed.

- Exposure to a cold climate is associated with an increased morbidity and mortality, but the specific mechanisms are largely unknown. People with cardiopulmonary disease and winter endurance athletes are particularly vulnerable. This study aimed to map multiple domains of airway responses to exercise in subzero temperature in healthy individuals.Thirty-one healthy subjects underwent whole-body exposures for 50 minutes on two occasions in an environmental chamber with intermittent moderate-intensity exercise in +10 °C and -10 °C. Lung function, plasma/urine CC16 , and symptoms were investigated before and after exposures.Compared to baseline, exercise in -10 °C decreased FEV1 (p=0.002), FEV1/FVC (p<0.001), and increased R20Hz (p=0.016), with no differences between exposures. Reactance increased after +10 °C (p=0.005), which differed (p=0.042) from a blunted response after exercise in -10 °C. Plasma CC16 increased significantly within exposures, without differences between exposures. Exercise in -10 °C elicited more intense symptoms from the upper airways, compared to +10 °C. Symptoms from the lower airways were few and mild. Short-duration moderate-intensity exercise in -10 °C induces mild symptoms from the lower airways, no lung function decrements or enhanced leakage of biomarkers of airway epithelial injury, and no peripheral bronchodilatation, compared to exercise in +10 °C.

Tidskriftsartikel (refereegranskat)abstract
- Progress in decreasing ischemic complications in acute coronary syndrome (ACS) has come at the expense of increased bleeding risk. We estimated the long-term, post-discharge incidence of serious bleeding, characterized bleeding type, and identified predictors of bleeding and its impact on mortality in an unselected cohort of patients with ACS. In this population-based study, we included 1379 patients identified with an ACS, 2010–2014. Serious bleeding was defined as intracranial hemorrhage (ICH), bleeding requiring hospital admission, or bleeding requiring transfusion or surgery. During a median 4.6-year follow-up, 85 patients had ≥ 1 serious bleed (cumulative incidence, 8.6%; 95% confidence interval (CI) 8.3–8.9). A subgroup of 557 patients, aged ≥ 75 years had a higher incidence (13.4%) than younger patients (6.0%). The most common bleeding site was gastrointestinal (51%), followed by ICH (27%). Sixteen percent had a recurrence. Risk factors for serious bleeding were age ≥ 75 years, lower baseline hemoglobin (Hb) value, previous hypertension or heart failure. Serious bleeding was associated with increased mortality. Bleeding after ACS was fairly frequent and the most common bleeding site was gastrointestinal. Older age, lower baseline Hb value, hypertension and heart failure predicted bleeding. Bleeding did independently predict mortality.

- Objective: The prevalence of asthma among elite endurance athletes is high, but less is known about the incidence of asthma among athletes. The aim of this study was to examine the incidence rate of physician-diagnosed asthma among elite endurance athletes.Method: An annual postal questionnaire was sent to an open prospective cohort of elite endurance athletes between 2011 and 2015. Athletes from Swedish National teams, students at universities with elite sport partnership, and pupils at Swedish National elite sport schools, competing in cross-country skiing, biathlon, ski orienteering, or orienteering were invited (n = 666). Incidence rate of physician-diagnosed asthma was calculated among those without asthma at baseline (n = 449). Risk factors for incident physician-diagnosed asthma were identified using a multivariate logistic regression analysis.Results: Response rate was 88.7% (n = 591) at baseline. The median age of participants was 17 (range 15–36) years at inclusion. The study population included 407 (69%) skiers and 184 (31%) orienteers. The prevalence of asthma at baseline was 23.9% (n = 141). Incidence rate (95% confidence interval [CI]) of physician-diagnosed asthma was 61.2 (45.7–80.3) per 1,000 person-years. Risk factors (odds ratio [OR (95% CI)]) for incident physician-diagnosed asthma were family history of asthma (1.97 [1.04–3.68]), being a skier (3.01 [1.42–7.21]), and wheezing without having a cold (4.15 [1.81–9.26]).Conclusion: The incidence rate of physician-diagnosed asthma is high among Swedish elite endurance athletes.

Diagnostic accuracy of the iNPH Radscale in idiopathic normal pressure hydrocephalus
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Background and purpose: The idiopathic normal pressure hydrocephalus (iNPH) Radscale was developed to standardize the evaluation of radiological signs in iNPH. The purpose of this study was to estimate the diagnostic accuracy of the iNPH Radscale in a sample of "true positive" and "true negative" cases.Methods: Seventy-five patients with definite iNPH, i.e. who had improved at clinical follow-up one year after ventriculoperitoneal shunt surgery, were compared with 55 asymptomatic individuals from the general population. A radiologist assessed the seven radiological features of the iNPH Radscale in computed tomography of the brain in the patients (preoperatively) and controls.Results: The iNPH Radscale score was significantly higher in the iNPH group (Median = 10, interquartile range 9–11) than in the control group (Median = 1, interquartile range 1–2) (p <0.001). Receiver operated characteristics analysis yielded an area under the curve of 99.7%, and an iNPH Radscale score ≤ 4 identified those without iNPH, with a sensitivity of 100%, specificity of 96% and overall accuracy of 98.5%.Conclusions: In this study, iNPH Radscale could accurately discriminate between patients with definite iNPH and asymptomatic individuals over 65 years old. According to the results, a diagnosis of iNPH is very likely in patients with an iNPH Radscale score above 8 and corresponding clinical symptoms. On the other hand, the diagnosis should be questioned when the iNPH Radscale score is below the cut-off level of 4. We conclude that the iNPH Radscale could work as a diagnostic screening tool to detect iNPH. Whether the scale also can be used to predict shunt outcome needs further studies.
