The association between playing professional American football and longevity.

Recent research concludes that professional American football players (hereafter, "football players") live longer than American men in general, despite experiencing higher rates of chronic traumatic encephalopathy (CTE) and cardiovascular disease (CVD). This suggests that the longevity-enhancing benefits of playing football (e.g., physical fitness, money) outweigh the costs associated with CTE, CVD, and other longevity detriments of playing football. However, these surprising results may be the consequence of flawed research design. To investigate, we conducted two analyses. In analysis 1, we compared a) all professional American football players whose first season was 1986 or between 1988 and 1995 to b) a random sample of same-age American men observed as part of the National Health Interview Surveys in those same years selected on good health, at least 3 y of college, and not being poor. The exposure consists of playing one or more games of professional football; the outcome is risk of death within 25 y. In analysis 2, we use data on 1,365 men drafted to play in the (American) National Football League in the 1950s-906 of whom ultimately played professional football, and 459 of whom never played a game in any professional league. We estimate the association between playing football and survival through early 2023. In both analyses, we investigate differences between linemen and other position players. In contrast to most prior research, in both analyses, we find that linemen died earlier than otherwise similar men; men who played other positions died no earlier (or later).

Intercalant-induced V t2g orbital occupation in vanadium oxide cathode toward fast-charging aqueous zinc-ion batteries.

Intercalation-type layered oxides have been widely explored as cathode materials for aqueous zinc-ion batteries (ZIBs). Although high-rate capability has been achieved based on the pillar effect of various intercalants for widening interlayer space, an in-depth understanding of atomic orbital variations induced by intercalants is still unknown. Herein, we design an NH4+-intercalated vanadium oxide (NH4+-V2O5) for high-rate ZIBs, together with deeply investigating the role of the intercalant in terms of atomic orbital. Besides extended layer spacing, our X-ray spectroscopies reveal that the insertion of NH4+ could promote electron transition to 3dxy state of V t2g orbital in V2O5, which significantly accelerates the electron transfer and Zn-ion migration, further verified by DFT calculations. As results, the NH4+-V2O5 electrode delivers a high capacity of 430.0 mA h g-1 at 0.1 A g-1, especially excellent rate capability (101.0 mA h g-1 at 200 C), enabling fast charging within 18 s. Moreover, the reversible V t2g orbital and lattice space variation during cycling are found via ex-situ soft X-ray absorption spectrum and in-situ synchrotron radiation X-ray diffraction, respectively. This work provides an insight at orbital level in advanced cathode materials.

AIM: The "2024 AHA/ACC/AMSSM/HRS/PACES/SCMR Guideline for the Management of Hypertrophic Cardiomyopathy" provides recommendations to guide clinicians in the management of patients with hypertrophic cardiomyopathy. METHODS: A comprehensive literature search was conducted from September 14, 2022, to November 22, 2022, encompassing studies, reviews, and other evidence on human subjects that were published in English from PubMed, EMBASE, the Cochrane Library, the Agency for Healthcare Research and Quality, and other selected databases relevant to this guideline. Additional relevant studies, published through May 23, 2023, during the guideline writing process, were also considered by the writing committee and added to the evidence tables, where appropriate. STRUCTURE: Hypertrophic cardiomyopathy remains a common genetic heart disease reported in populations globally. Recommendations from the "2020 AHA/ACC Guideline for the Diagnosis and Treatment of Patients With Hypertrophic Cardiomyopathy" have been updated with new evidence to guide clinicians.

Trends in social mobility in postrevolution China.

In this paper, we study long-term trends in social mobility in the People's Republic of China since its inception in 1949, with two operationalizations: 1) intergenerational occupational mobility and 2) intergenerational educational mobility. We draw on an accumulation of administrative and survey data and provide comparable estimates of these measures for birth cohorts born after 1945. To help interpret the results, we compare trends in China to those in the United States for the same birth cohorts. We find an increase in intergenerational occupational mobility in China due to its rapid industrialization in recent decades. Net of industrialization, however, intergenerational occupational mobility has been declining for recent cohorts. Intergenerational educational mobility in China shows a similar declining trend. In addition, mobility patterns have differed greatly by gender, with women in earlier cohorts and from a rural origin particularly disadvantaged. We attribute the general decline in social mobility to market forces that have taken hold since China's economic reform that began in 1978. In contrast, social mobility by both measures has been relatively stable in the United States. However, while social mobility in China has trended downward, it is still higher than that in the United States, except for women's educational mobility.

Hydrogen-Driven Low-Temperature Topotactic Transition in Nanocomb Cobaltite for Ultralow Power Ionic-Magnetic Coupled Applications.

We reversibly control ferromagnetic-antiferromagnetic ordering in an insulating ground state by annealing tensile-strained LaCoO3 films in hydrogen. This ionic-magnetic coupling occurs due to the hydrogen-driven topotactic transition between perovskite LaCoO3 and brownmillerite La2Co2O5 at a lower temperature (125-200 °C) and within a shorter time (3-10 min) than the oxygen-driven effect (500 °C, tens of hours). The X-ray and optical spectroscopic analyses reveal that the transition results from hydrogen-driven filling of correlated electrons in the Co 3d-orbitals, which successively releases oxygen by destabilizing the CoO6 octahedra into CoO4 tetrahedra. The transition is accelerated by surface exchange, diffusion of hydrogen in and oxygen out through atomically ordered oxygen vacancy "nanocomb" stripes in the tensile-strained LaCoO3 films. Our ionic-magnetic coupling with fast operation, good reproducibility, and long-term stability is a proof-of-principle demonstration of high-performance ultralow power magnetic switching devices for sensors, energy, and artificial intelligence applications, which are keys for attaining carbon neutrality.

Effect of climate on emergency department admissions for renal colic: a comparative analysis of sedentary and non-sedentary lifestyles.

OBJECTIVE: To investigate the impact of climate and seasonal variations on emergency department (ED) admissions for renal colic, while specifically comparing the differences between individuals with sedentary and non-sedentary lifestyles. PATIENTS AND METHODS: A retrospective, single center study was conducted. Between the years 2017- 2020, medical records of patients admitted to the ED with renal colic, found to harbor ureteric stones on CT scans, were examined. Data on patients' occupational activities was collected through telephone questionnaires. Patients were categorized into two groups: sedentary and active. Precise weather data was obtained from the Israeli Meteorological Service website. The monthly average daily maximum temperatures were calculated. RESULTS: In the final sample of 560 participants, 285 were in the sedentary group, and 275 were in the active group. The study population consisted of 78.1% males and 21.9% females, with consistent gender ratios in both occupational groups. Prevalence of uric acid stones was higher in the sedentary group (p < 0.05). While there was a slight increase in admissions during the summer, seasonal distribution did not significantly differ among occupational groups. The study found no significant differences in admissions across different temperature ranges. Both groups exhibited a pattern of increased referrals during the summer and reduced referrals in the colder winter months. The baseline data revealed notable differences between the sedentary and active groups, particularly in the prevalence of uric acid stones. CONCLUSIONS: Climate factors, including temperature and seasonal variations, had limited impact on ED admissions for renal colic in patients with kidney stones, irrespective of their sedentary or active lifestyles. Both groups exhibited similar admission patterns, with a higher rate of admissions during the summer and a lower rate of admissions during the winter.

Birth defects among offspring of California firefighters, 2007-2019.

PURPOSE: Limited research examines birth defects from maternal or paternal firefighting exposure. This study aims to assess if maternal or paternal occupational exposure to firefighting during periconception is associated with offspring birth defects. METHODS: Data from California birth certificates (2007-2019) were linked to maternal / offspring hospitalization records. Occupation during the periconceptional period was categorized from vital statistics as the following: paternal non-firefighting (n = 4,135,849), paternal firefighting (n = 22,732), maternal non-firefighting (n = 3,332,255) and maternal firefighting (n = 502). Birth defects were identified using ICD codes, grouped by anatomical regions. Adjusted odds ratios were estimated, and sensitivity analyses explored police officer reference groups and detailed birth defect categories. RESULTS: Offspring of paternal firefighters had lower odds of circulatory defects (aOR = 0.9, 95% CI 0.8, 1.0), oral clefts (aOR = 0.6, 95% CI 0.4, 0.8) and respiratory defects (0.7, 95% CI 0.6, 0.9) compared to paternal non-firefighters. Associations between maternal firefighting and offspring birth defects were imprecise. Substituting police officers as the reference group attenuated findings. CONCLUSIONS: Offspring of paternal firefighters may have similar or slightly lower birth defect odds compared to offspring of non-firefighters. Limited data was available for assessing maternal firefighting outcomes. Future studies should prioritize studies using occupational exposure matrices to limit misclassification of exposure.

Air Pollution and Rheumatoid Arthritis Risk and Progression: Implications for the Mucosal Origins Hypothesis and Climate Change for RA Pathogenesis.

PURPOSE OF REVIEW: The goal of this review paper is to summarize the main research and findings regarding air pollution and its association with the risk and progression of rheumatoid arthritis (RA). RECENT FINDINGS: The most studied components of air pollution included particulate matter of ≤ 2.5 microns in diameter (PM2.5), PM10, carbon monoxide (CO), nitrogen dioxide (NO2), nitric oxide (NOx), sulfur dioxide (SO2), and ozone (O3). In addition, specific occupations and occupational inhalants have been investigated for RA risk. Several studies showed that increased exposure to air pollutants increased the risk of developing RA, particularly seropositive RA. There was evidence of gene-inhalant interactions for seropositive RA risk. Fewer studies have been conducted on RA disease activity and bone erosions. Some studies suggest that patients with RA-associated interstitial lung disease may have worse outcomes if exposed to air pollution. We summarized associations between air pollution and increased RA risk, including RA-associated interstitial lung disease. Relatively few studies investigated air pollution and RA disease activity or other outcomes. These results suggest an important role of air pollution for seropositive RA development and suggest that climate change could be a driver in increasing RA incidence as air pollution increases.

Occupational groups and lower urinary tract symptoms: A cross-sectional analysis of women in the Boston Area Community Health Study.

OBJECTIVES: The objective of this study is to inform our hypothesis that the workplace toileting environment may impact lower urinary tract symptoms (LUTS); we examined the prevalence of LUTS across occupational groups in the Boston Area Community Health Survey. METHODS: At baseline, women (n = 3205) reported their occupation and frequency of 15 LUTS. Using the US Department of Labor's Standard Occupational Classification (SOC) system, we categorized women into 11 standard occupational groups. Prevalence ratios (PRs) were calculated by log-link generalized linear models, adjusting for age, race, education, fluid intake, and parity. Women classified in Office and Administrative Support were used as the reference group given their potential for fewer workplace toileting restrictions. RESULTS: Of the 3189 women with complete data, 68% of women reported any LUTS, ranging from 57% to 82% across the SOCs. Relative to women in Office and Administrative Support (n = 576), women in Computing, Engineering, and Science (n = 64) were more likely to report any LUTS (PR = 1.2, 95% confidence interval [95% CI]: 1.0-1.4) and urinating again in <2 h (PR = 1.7, 95% CI: 1.4-2.2), and women in Education, Legal, Community Service, Arts, and Media (n = 477), as well as Healthcare Practitioner and Technical Occupations (n = 162), were less likely to report perceived frequent daytime urination (PR = 0.6, 95% CI: 0.5-0.9 and PR = 0.6, 95% CI: 0.4-0.9, respectively). CONCLUSIONS: Our cross-sectional findings suggest that urination frequency varies across understudied occupational groups with various workplace toileting environments. Future studies should examine this relationship prospectively to inform the influence of workplace toileting environments on urination frequency, as well as the development and/or worsening of LUTS.

Job strain, occupation, and bladder health among women.

OBJECTIVES: Lower urinary tract symptoms (LUTS) are common among employed women. An underexplored topic is whether characteristics of women's occupations may influence LUTS. The present study examined whether job strain and its individual components (psychological demands, decision latitude) were associated with greater LUTS and their impact and whether, compared to managerial and professional occupations, occupations characterized by manual labor, sales, service, nursing, and teaching were associated with greater LUTS and their impact. METHODS: Coronary Artery Risk Development in Young Adults cohort study data were analyzed. Job strain and occupation were assessed in 1987-88 and 1995-96. In 2012-13, LUTS and their impact were assessed. LUTS/impact category (a composite variable ranging from bladder health to mild, moderate, and severe LUTS/impact) was regressed on job strain and occupation in separate analyses, adjusting for age, race, parity, education, and financial hardship (n = 1006). RESULTS: Job strain and its individual components were not associated with LUTS/impact. In comparison to managerial and professional occupations, service occupations in 1987-88 and 1995-96 were both associated with greater odds of LUTS/impact in proportional odds logistic regression analyses. Employment as a nurse, health assistant, or health aide in 1995-96 was associated with greater odds of any LUTS/impact versus bladder health. Support positions in 1987-88 and sales positions in 1995-96 were associated with greater odds of moderate or severe LUTS/impact versus bladder health or mild LUTS/impact. CONCLUSIONS: Future research should examine characteristics of workplaces that may promote or constrain bladder health (e.g., time and autonomy to void when desired, infrastructure to void).

Occupational exposure to diesel exhausts and liver and pancreatic cancers: a systematic review and meta-analysis.

BACKGROUND: Diesel exhaust (DE) is human carcinogen with sufficient evidence only for lung cancer. Systematic evidence on other cancer types is scarce, thus we aimed to systematically review current literature on the association between occupational DE exposure and risk of liver and pancreatic cancers. METHODS: We performed a systematic literature review to identify cohort studies on occupational DE exposure and risk of cancers other than lung. We computed pooled relative risks (RRs) and corresponding 95% confidence intervals (CIs) for liver and pancreatic cancers using DerSimonian and Laird random-effects model. RESULTS: Fifteen studies reporting results on pancreatic cancer and fourteen on liver cancer were included. We found a weakly increased risk of pancreatic cancer in workers exposed to DE (RR: 1.07, 95% CI: 1.00, 1.14), mainly driven by results on incidence (RR: 1.11, 95% CI: 1.02, 1.22). As for liver cancer, results were suggestive of a positive association (RR: 1.09; 95% CI: 0.99, 1.19), although a significant estimate was present in studies published before 2000 (RR: 1.41; 95% CI: 1.09, 1.82). We found no compelling evidence of publication bias. CONCLUSIONS: Our findings suggest an association between occupational DE exposure and liver and pancreatic cancer. Further studies with detailed exposure assessment, environmental monitoring data, and appropriate control for confounders are warranted.

Initial evaluation of measurement properties of the Work Environment Impact Questionnaire (WEIQ) - using Rasch analysis.

BACKGROUND: To provide both preventive and rehabilitative conditions in a workplace, one must understand how employees experience work demands. Such an understanding can be obtained from each individual with valid and quality-assured questionnaires. The Work Environment Impact Questionnaire (WEIQ) is a new questionnaire for measuring employees' self-perceived work ability in relation to their specific workplace environment. The purpose of this study was to assess the measurement properties in terms of construct validity of the WEIQ. METHODS: A cross-sectional survey study was conducted with 288 respondents from three different workplaces involving assisted living personnel, vocational rehabilitation personnel and personnel at a research institute. The measurement properties of the WEIQ were assessed according to Rasch Measurement Theory (RMT), including assessment of item-to-sample targeting, threshold ordering, item fit statistics, unidimensionality and reliability. RESULTS: Item fit, i.e., fit residuals, item characteristic curves (ICC) and chi square values, were all satisfactory, and no disordered thresholds were present after collapsing the lowest response categories. However, issues with local dependent (LD) item correlations was present in 7.6% cases, four items showed statistically significant differential item functioning (DIF), where 11% of the respondents had person fit residuals outside the recommended range of ± 2.5 and the t-test for unidimensionality did not meet the criterion of 5%. Scale-to-sample targeting and reliability (0.92) were good. LD could be resolved with testlets and at the same time maintaining fit and improving dimensionality, but then the reliability decreased to 0.82. CONCLUSIONS: This study provides an initial validation of the WEIQ to be used for assessing employees' self-perceived work ability. Most measurement properties were acceptable, but further exploration of LD, DIF and unidimensionality in additional work settings and with larger sample sizes is warranted. TRIAL REGISTRATION: Not applicable.

The effect of retirement eligibility on mental health in the United Kingdom: Heterogeneous effects by occupation.

I investigate heterogeneity across occupational characteristics in the effect of retirement eligibility on mental health in the United Kingdom. I use K-means clustering to define three occupational clusters, differing across multiple dimensions. I estimate the effect of retirement eligibility using a Regression Discontinuity Design, allowing the effect to differ by cluster. The effects of retirement eligibility are beneficial, and greater in two clusters: one comprised of white-collar jobs in an office setting and another of blue-collar jobs with high physical demands and hazards. The cluster with smaller benefits mixes blue- and white-collar uncompetitive jobs with high levels of customer interaction. The results have implications for the distributional effect of raising the retirement age.

Prevalence and Burden of Asthma among US Working Adults by industry and Occupation-United States, 2020-2021.

OBJECTIVES: Assess prevalence of current asthma, asthma attacks/episodes, and asthma-related emergency room (ER) visits by industry and occupation and estimate the proportion of current asthma cases associated with employment during 2020-2021. METHODS: The 2020-2021 National Health Interview Survey data for persons aged ≥18 years who were employed at any time during the 12 months prior to the interview were analyzed. RESULTS: An estimated 12.7 million US working adults had current asthma. Of those, 40% had an asthma attack/episode and 8.6% had an asthma-related ER visit. Prevalence varied by sociodemographic characteristics, industry, and occupation. Highest asthma prevalence was among workers in the administrative, support, waste management, and remediation industry and the community and social services occupation. Nearly half of workers with current asthma in the arts, entertainment, and recreation industry and arts, design, entertainment, sports, and media occupations reported having an asthma attack/episode. Workers in the accommodations and food services industry and food preparation and serving related occupation had the highest asthma-related ER visits. The proportion of current asthma cases attributable to employment was estimated to be 9.2% by industry and 12.2% by occupation. CONCLUSION: An estimated 1.2-1.5 million asthma cases among workers might be attributable to employment by industry and occupation. Disparities in asthma prevalence, asthma attacks/episodes and asthma-related ER visits among workers exits. These findings underscore the importance of early identification of asthma cases in relation to work and implementation of targeted interventions (including, training and education, personal protective equipment use, health surveillance, workplace policies), especially among workers employed in industries and occupations with elevated asthma prevalence.

Occupational benzene exposure and colorectal cancer: A systematic review and meta-analysis.

Recent reports suggest that benzene exposure may be associated with solid cancers, such as lung and bladder cancers. Instead, evidence on the association between benzene and colorectal cancer (CRC) is sparse. Thus, we aimed to summarize current literature on the association between occupational benzene exposure and CRC. We searched Pubmed, Embase (through Ovid), and Scopus to retrieve cohort and nested case-control studies on the association between occupational benzene exposure and solid cancers. The search was initially completed in December 2022 and later updated in April 2024. We assessed quality of included studies using a modified version of Newcastle-Ottawa Scale. We computed pooled relative risks (RRs) and corresponding 95% confidence intervals (CIs) of CRC according to occupational benzene exposure, using the Paule-Mandel method. Twenty-eight studies were included in the meta-analysis. Most of them were conducted in Europe or North America (82.1%) and were industry-based (89.3%). Pooled RRs comparing workers exposed to benzene with those who were unexposed for incidence and mortality were 1.10 (95% CI: 1.06, 1.15) and 1.04 (95% CI: 0.97, 1.11) for CRC, 1.12 (95% CI: 1.01, 1.24) and 1.08 (95% CI: 0.99, 1.19) for colon cancer, and 1.04 (95% CI: 0.94, 1.14) and 1.05 (95% CI: 0.92, 1.19) for rectal cancer, respectively. Only one study supported the occurrence of a dose-response relationship between occupational benzene exposure and CRC, while others found no increase in risk according to dose of exposure or duration of employment. Our findings suggest that occupational benzene exposure may be associated with CRC. Further research with detailed assessment of individual-level exposure is warranted to confirm our results.

Occupational arsenic exposure and digestive and head and neck cancers: a systematic review and meta-analysis.

Arsenic is a known carcinogen for the lungs, the bladder, and the skin, while systematic evidence on other cancer types is lacking, especially for occupational exposure. Thus, we aimed to systematically summarize current evidence on the association between occupational arsenic exposure and digestive cancers, including head and neck cancer (HNC). We conducted a systematic review on Pubmed, Web of Science, and Embase search engines. We computed pooled relative risks (RRs) and corresponding 95% confidence intervals (CIs) using DerSimonian and Laird random-effects model. Occurrence of publication bias was assessed using contour-enhanced funnel plots and Egger's test. Twenty-two studies on digestive cancers and 11 on HNC were included in the meta-analysis. RRs for the association with occupational exposure to arsenic of 1.23 (95% CI: 1.07-1.40; I2=72.3%, p<0.001) and 1.08 (95% CI: 0.76-1.53; I2=76.6%, p<0.001) for digestive cancer and HNC, respectively, were observed. As for specific cancer types, arsenic was associated with rectal cancer (RR: 1.51; 95% CI: 1.003-2.28; I2=37.0%, p=0.174), but not with other investigated cancer types. No clear evidence of publication bias was found. The results of our study suggest that the observed association between occupational arsenic exposure and digestive cancer might be mainly driven by a positive association for rectal cancer, while arsenic exposure did not appear to be associated with HNC. However, further high-quality studies with detailed assessment of arsenic exposure are warranted to clarify the potential association of arsenic with digestive cancers and HNC.

The Effect of Proprioceptive Training on Hand Function and Activity Limitation After Open Carpal Tunnel Release Surgery: A Randomized Controlled Study.

OBJECTIVE: To investigate the effect of proprioceptive training on hand function and activity limitation in patients undergoing open carpal tunnel release surgery. DESIGN: Randomized controlled study. SETTING: A university hospital. PARTICIPANTS: Thirty patients were included in the study and randomized to proprioceptive training (PT) and conventional rehabilitation (CR) groups. INTERVENTION: One week after surgery, both groups received CR for 6 weeks. All participants were asked to perform home-based exercises daily in 3 sets with 10 repetitions. For the PT group, a 6-step PT program was conducted starting from Week 6. Both groups received face-to-face interventions twice a week for 12 weeks. MAIN OUTCOME MEASURES: The outcome measures included the Purdue Pegboard Test (PPT), the joint position sense test (JPST), the Boston Carpal Tunnel Questionnaire, and the Patient-Specific Functional Scale. In total, 3 assessments were performed (at 1, 6 and 12 weeks postoperatively). RESULTS: In the PT group, the results for PPT were statistically significant (P<.05). Although there was a greater decrease in the absolute angular error value (JPST) of the PT group compared to the CR group, the difference was nonsignificant (P>.05). Similar reductions in activity limitation were seen in both groups (PT: 176%, CR: 175%). Symptom severity decreased by 40% in the PT group vs 32% in the CR group. The effect sizes were larger for the changes between the second and third assessments in the PT group compared to the CR group in all parameters tested. CONCLUSION: When applied after carpal tunnel release surgery, PT may potentially to improve hand functions, reduce activity limitation, increase participation in activities of daily living, and thus improve quality of life.

Effects of portable pedal machines at work on lipoprotein subfraction profile in sedentary workers - the REMOVE study.

BACKGROUND: Sedentary behaviour at work is a major cause of atherosclerosis, particularly in tertiary workers. However, no studies have ever assessed the effect of active workstation on lipoprotein subfraction profile. This study aimed to evaluate the effect of 12-week portable pedal machines (PPMs) on lipoprotein subfraction profile among healthy sedentary workers. METHODS: Healthy administrative workers were randomized into an intervention group using PPMs for 12 weeks or a control group using normal-desk. Lipoprotein subfractions were assessed using Lipoprint® electrophoresis. Main outcomes were explored using mixed models with sensitivity analyses (four models). RESULTS: We included 40 participants (43.7 ± 8.6 years old, 100% women, BMI 23.8 ± 3.4 kg/m2; sedentary time at work 7.7 ± 1.8 h/day). Groups did not differ at baseline in any outcomes. 32 participants finished the trial. Changes in lipoprotein subfractions were especially marked for LDL profile. There was an interaction time x group for all parameters related to LDL and their subfractions: total LDL-cholesterol (p = 0.012), LDL particle size (p = 0.027), large LDL subfractions 1 and 2 (p = 0.001), and small dense LDL subfractions 3 to 7 (p = 0.046), using the crude model. The interaction reflects difference in the direction of changes between groups. The LDL particle size significantly increased in the intervention group (from 271.9 ± 2.5 at t0 to 272.8 ± 1.9 Ångström at t1, p = 0.037) while it did not change in the control group (272.5 ± 1.7 at t0 to 271.8 ± 1.5Å at t1, p = 0.52). All interactions were constantly significant whatever the models. Influencing variables were mainly stress at work that was associated with an increase in total LDL-cholesterol (coefficient 3.15, 95CI 0.20 to 6.11 mg/dl, p = 0.038), and BMI that was associated with Large-LDL, Large-HDL, IDL-C and triglycerides. CONCLUSIONS: Lipoprotein profile was improved after a 12-week PPMs intervention at work in healthy administrative workers. Changes were mainly showed for LDL and LDL subfractions. Lipoprotein profile was worsened by stress at work, BMI and age. TRIAL REGISTRATION: NCT04153214.

Association between night work and prostate cancer: a systematic review and meta-analysis.

OBJECTIVE: The aim was to conduct a systematic review and meta-analysis to study the association between night work and the development of prostate cancer. METHODS: A systematic literature search was conducted in CINAHL, Embase, MEDLINE, and Web of Science. Studies were included based on a PECOS; the population included men in/above the working age, exposure defined as night work, outcome defined as prostate cancer, and study design restricted to cohort studies. The exclusion of articles, risk-of-bias assessment, and data extraction were performed by two reviewers. A meta-analysis was conducted using a random-effects model, including a sensitivity analysis stratified based on the risk-of-bias assessment. We evaluated publication bias using a funnel plot and Egger´s test, and the level of evidence was assessed using GRADE. RESULTS: A total of 528 articles were identified, and eight cohort studies were included. Three studies had a moderate risk of bias, while five studies had a high risk of bias. The meta-analysis showed a pooled hazard ratio (HR) of 1.0 (95% CI 0.6-1.7). In the sensitivity analysis, moderate vs. high risk-of-bias studies showed a pooled HR of 1.2 (95% CI 0.3-4.1) and 0.9 (95% CI 0.6-1.3), respectively. Based on GRADE, the level of evidence was rated low. CONCLUSION: We found no association between night work and the development of prostate cancer. The evidence was assessed as limited and inconsistent. Future studies encompassing consistent definitions of night work, including objective exposure data, are highly warranted.

Exploring the working life of people with multiple sclerosis during the COVID-19 pandemic in Sweden.

BACKGROUND: The COVID-19 pandemic led to vast changes in working life and conditions in which we work. These changes may affect people with multiple sclerosis (PwMS) differently. We aimed to describe the working situation of PwMS during the COVID-19 pandemic and the pandemic's impact on their working lives. METHODS: All individuals aged 20-50 listed in the Swedish Multiple Sclerosis Registry were invited to participate in an online survey in 2021. Closed and open-ended responses linked to individual-level register data were used in this exploratory mixed-methods study. Differences in the proportions reporting specific impacts were assessed with chi-square tests by sex, MS severity, education, and profession. The open-ended answers were analysed through content analysis. RESULTS: Over 8500 PwMS were invited (52% response rate). We included the 3887 respondents who answered questions about the impact of the pandemic on working life. Most (93.7%) reported being in paid work. An impact of the ongoing pandemic to one's daily occupation was reported by 26.2%, with different characteristics observed across the impacts. Four categories of type of answers were identified from the open-ended answers: Direct impact on one's occupation, Disclosing or concealing MS in the workplace, Worry and uncertainty, and Broader impact to life situation. CONCLUSIONS: PwMS navigated the pandemic by interrupting as well as continuing their working lives. Many PwMS reported that the pandemic did not affect their work situation. However, the reported impacts differed among the participants and a sense of uncertainty and worry was often underlying their statements. Lessons from the pandemic may support future work participation.
