Purpose: To determine the change in the sagittal and vertical position of mini-implants placed in the maxilla during distal movement of the entire maxillary dentition. Materials and Methods: Overall, 28 mini-implants (1 placed on each side in 14 patients) were evaluated in healthy patients aged 15 to 25 years old. CBCTs were taken immediately after leveling and aligning prior to distalization (T1) and after 6 months (T2) to evaluate the distal movement of the maxillary teeth and position of the mini-implants. The vertical and sagittal angulation of each mini-implant was measured at T1 and T2. The linear distance between the mini-implant and the alveolar crest, the maxillary sinus, the maxillary second premolar, and the maxillary first permanent molar were measured. The change in angulation and the linear displacement of the mini-implant were evaluated in the vertical and sagittal plane. Wilcoxon signed rank test was performed to determine if there was a statistically significant change in the position of the mini-implant. Results: Vertically, there was a significant change in the linear distance between the mini-implant and the alveolar crest on the right side (P ≤ .006) as well as the mini-implant and the maxillary sinus on the left side (P ≤ .003). Sagittally, there was a statistically significant rotation of the mini-implant occlusally (left side P ≤ .004 and right side P≤ .002). The head and tip of the mini-implant were displaced toward the maxillary second premolar and away from the maxillary first permanent molar, respectively. There was a significant relative displacement of the mini-implant anteriorly away from the maxillary first permanent molar (left side P ≤ .026 and right side P ≤ .041) and closer to the maxillary second premolar (left side: P ≤.011 and right side: P≤ .002). Conclusions: There was a statistically and clinically significant rotation of the mini-implant in the vertical and sagittal direction during distal movement of the entire maxillary arch. The linear displacement of the mini-implant was more pronounced in the sagittal direction than the vertical direction. [ABSTRACT FROM AUTHOR]

OBJECTIVE: Affective symptoms such as anxiety, low mood, and loneliness are prevalent and highly debilitating symptoms among older adults (OA). Serotonergic psychedelics are currently investigated as novel interventions for affective disorders, yet little is known regarding their effects in OA. We investigated the mental health effects and psychological mechanisms of guided psychedelic group experiences in OA and a matched sample of younger adults (YA). METHODS: Using a prospective observational cohort design, we identified 62 OA (age ≥60 years) and 62 matched YA who completed surveys two weeks before, a day, two weeks, four weeks, and six months after a psychedelic group session. Mixed linear regression analyses were used to investigate longitudinal well-being changes, as well as baseline, acute, and post-acute predictors of change. RESULTS: OA showed post-psychedelic well-being improvements similar to matched YA. Among baseline predictors, presence of a lifetime psychiatric diagnosis was associated with greater well-being increases in OA (B = 6.72, p = .016 at the four-week key-endpoint). Compared to YA, acute subjective psychedelic effects were less intense in OA and did not significantly predict prospective well-being changes. However, relational experiences before and after psychedelic sessions emerged as predictors in OA (r(36) = .37,p = 0.025). CONCLUSIONS: Guided psychedelic group sessions enhance well-being in OA in line with prior naturalistic and controlled studies in YA. Interestingly, acute psychedelic effects in OA are attenuated and less predictive of well-being improvements, with relational experiences related to the group setting playing a more prominent role. Our present findings call for further research on the effects of psychedelics in OA.

BACKGROUND: Sedentary behavior is linked to excess fat mass; however, this association may be inconclusive due to potential measurement errors in self-reported sedentary behavior. OBJECTIVE: To assess the association between changes in sedentary behavior and fat mass in a Cohort of Health Workers (HWCS) from 2004 to 2010. METHODS: A total of 1,285 adults participating in the Cohort of Health Workers were evaluated in 2004 and 2010. Fat mass (kg) was measured by dual X-ray absorptiometry. A self-administered questionnaire was used to estimate the sedentary behavior. Sedentary behavior was also estimated using accelerometry in a sample of 142 health workers. Accelerometry data were used to correct self-reported sedentary behavior using a generalized linear model, which included values for sleeping time, age, sex, sedentary behavior, glucose, and triglycerides. Concordance between both methods was assessed using a kappa and Bland-Altman analysis. Once sedentary behavior was corrected, the values were used to evaluate the association between changes in sedentary behavior and body fat mass using a fixed effect model in the cohort, adjusting for confounders. RESULTS: Self-reported sedentary behavior was 2.8 ± 1.8 and 2.3 ± 1.6 h/day, and body fat mass was 24.9 ± 8.1 and 26.8 ± 8.5 kg in 2004 and 2010, respectively. After applying the correction model, the self-reported sedentary behavior was 7.6 ± 1.2 and 7.5 ± 1.2 h/day in 2004 and 2010, respectively. For every hour increase in corrected sedentary behavior, there was an observed increase of 0.847 (p > 0.001) kg in body fat mass during the 6.8 years in the Cohort of Health Workers from 2004 to 2010. Conversely, non-corrected self-reported sedentary behavior was associated with a non-significant reduction of 0.097 kg (p = 0.228) for every hour of sedentary behavior. CONCLUSIONS: Increased sedentary behavior was associated with increased body fat mass when corrected self-reported sedentary behavior was used. Implementing public health strategies to reduce sedentary behavior is imperative.

Background: This study aimed to explore the relationship between the changes in parent-related factors and preschoolers exceeding screen time (ST) recommendations. Methods: A longitudinal analysis using 2-year follow-up data from 4 kindergartens (n = 409) was conducted in Zhejiang, China, from 2019 to 2021. Multivariate logistic regression models were used to determine the potential parental modifiable predictors. Results: The significant associations of baseline ST, change in screen accessibility, and the interaction of preschooler ST with maternal ST change with preschooler follow-up ST were observed. For preschool-aged children with baseline ST ≤ 1 hour per day, the follow-up of preschoolers with ST > 1 hour per day increased significantly when parental clarity of their ST rules decreased or remained low. For preschool children with baseline ST > 1 hour per day, follow-up ST increased significantly when their father kept ST >2 hours per day, when the screen accessibility became or remained easy, or when parental awareness of the ST decreased. Conclusions: Changes in parental correlates played an important role in preschooler ST based on 2-year longitudinal data. Early interventions should focus on improving the clarity of parental rules and perceptions, as well as on reducing parental ST and accessibility of home screens. [ABSTRACT FROM AUTHOR]

Aims Methods Results Conclusion A data‐driven cluster analysis in a cohort of European individuals with type 2 diabetes (T2D) has previously identified four subgroups based on clinical characteristics. In the current study, we performed a comprehensive statistical assessment to (1) replicate the above‐mentioned original clusters; (2) derive de novo T2D subphenotypes in the Kooperative Gesundheitsforschung in der Region Augsburg (KORA) cohort and (3) describe underlying genetic risk and diabetes complications.We used data from n = 301 individuals with T2D from KORA FF4 study (Southern Germany). Original cluster replication was assessed forcing k = 4 clusters using three different hyperparameter combinations. De novo clusters were derived by open k‐means analysis. Stability of de novo clusters was assessed by assignment congruence over different variable sets and Jaccard indices. Distribution of polygenic risk scores and diabetes complications in the respective clusters were described as an indication of underlying heterogeneity.Original clusters did not replicate well, indicated by substantially different assignment frequencies and cluster characteristics between the original and current sample. De novo clustering using k = 3 clusters and including high sensitivity C‐reactive protein in the variable set showed high stability (all Jaccard indices >0.75). The three de novo clusters (n = 96, n = 172, n = 33, respectively) adequately captured heterogeneity within the sample and showed different distributions of polygenic risk scores and diabetes complications, that is, cluster 1 was characterized by insulin resistance with high neuropathy prevalence, cluster 2 was defined as age‐related diabetes and cluster 3 showed highest risk of genetic and obesity‐related diabetes.T2D subphenotyping based on its sample's own clinical characteristics leads to stable categorization and adequately reflects T2D heterogeneity.

The objective of this study was to ascertain the relationship between the weight-adjusted waist index (WWI) and the risk of stroke in an elderly hypertensive population, a relationship that has not been previously elucidated. The Cox regression model was employed to assess the correlation between baseline WWI measurements and the incidence of stroke. To further elucidate the shape of the association between baseline WWI and stroke, restricted cubic splines were employed. Furthermore, subgroup analyses and interaction tests were carried out to investigate potential heterogeneities. Our study cohort comprised 4962 hypertensive individuals aged 60 years or older with no prior history of stroke. Over a median follow-up of 3.2 years, we found 547 new-onset stroke cases. After adjusting for confounding variables, the Cox regression analysis revealed a positive association between baseline WWI and the risk of stroke, with hazard ratios (HRs) escalating progressively as WWI values increased. When compared to the lowest quartile of WWI, the highest quartile demonstrated an HR of 1.87 (95% CI, 1.44–2.42) for stroke. Subgroup analyses confirmed the consistency of this relationship across different demographic and clinical strata. The study findings indicate that an elevated WWI is significantly related with a higher risk of new-onset stroke among elderly patients with hypertension. These results underscore the importance of WWI as a potential risk stratification tool. To confirm these results and explore the causal mechanisms behind the observed correlation, more study is necessary. [ABSTRACT FROM AUTHOR]

Background: The effects of physical activity on the development of different types of cancers have not been comprehensively studied. This nationwide, population-based cohort study investigated the effects of leisure-time physical activity (LTPA) on the development of different types of cancer in Taiwanese adults. A total of 67,890 adult participants (≥ 18 y old) from five rounds (2001, 2005, 2009, 2013, and 2017) of the Taiwan National Health Interview Survey were included. LTPA was measured as the metabolic equivalent of task (MET) expenditure per week and was classified as inactive (< 1 MET-h), low (1-7.49 MET-h), or high (≥ 7.5 MET-h). The LTPA and other covariates were collected through in-person interviews at baseline. New-onset cancer was ascertained from histopathological reports. The Fine-Gray sub-distribution method, with death as a competing risk, was used to determine the impact of LTPA on incident cancer risk. Results: During the 844,337 person-years of follow-up, 4,435 individuals developed cancer. Compared to inactive adults, individuals engaging in high levels of LTPA (≥ 7.5 MET-h/week) were significantly associated with a reduced risk of developing cancer (adjusted hazard ratio [aHR] = 0.93; 95% confidence interval [CI] = 0.87–0.99). However, those with low levels of LTPA (1-7.49 MET-h/week) did not exhibit a significant association with a reduced risk of developing cancer (aHR = 1.00; 95% CI = 0.92–1.10). When considering specific types of cancers, participants with high levels of LTPA (≥ 7.5 MET-h/week) had a significantly lower risk of developing bladder cancer (aHR = 0.68; 95% CI = 0.47–0.99), cervical cancer (aHR = 0.48; 95% CI = 0.24–0.95), and thyroid cancer (aHR = 0.64; 95% CI = 0.44–0.93). Conclusions: Our findings suggest that high LTPA (≥ 7.5 MET-h/week) is significantly associated with a low risk of incident bladder, cervical, and thyroid cancers. Key points: This prospective cohort study with a mean follow-up of 12.4 years found that high leisure-time physical activity (≥ 7.5 MET-h/week) was significantly associated with a lower risk of incident cancer, including bladder, cervical, and thyroid cancer. Healthcare professionals should encourage inactive adults to perform leisure-time physical activities to reduce cancer risk. [ABSTRACT FROM AUTHOR]

Background: Systemic corticosteroid has been recommended for the treatment of severe acute exacerbations of chronic obstructive pulmonary disease (AECOPD). Little is known about the use of systemic corticosteroid in patients admitted to intensive care units (ICU) since most of previous trials excluded these critically ill patients. Methods: We conducted a matched cohort study based on the Medical Information Mart in Intensive Care-IV database. Patients with AECOPD in ICUs were included. Patients in the exposure group should be intravenously administrated with methylprednisolone or treated with oral prednisone within 24 h after ICU admission. The propensity score matching and multivariable analyses were used to adjust for covariates. The primary outcome was 28-day mortality, and secondary outcomes included ICU mortality, in-hospital mortality, the duration of ICU stay, and mechanical ventilation. Subgroup analyses for the primary outcome were performed according to age, sex, type of corticosteroid, type of ICU admission, type of mechanical ventilation, and co-morbidities/complications. Results: The entire cohort and the matched cohort included 763 and 412 patients, respectively. In the matched cohort, the use of systemic corticosteroid had no impact on 28-day mortality (OR: 1.00, 95% CI: 0.61–1.64, P = 1.000). The results kept consistent in all subgroups. Additionally, systemic corticosteroid showed no benefits on ICU mortality, in-hospital mortality, the length of ICU stay, and the duration of mechanical ventilation. Conclusions: The results of this study do not support routine use of systemic corticosteroid in patients with AECOPD admitted to ICUs. [ABSTRACT FROM AUTHOR]

ABSTRACT Spot central and peripheral blood pressure are predictors for future hypertension, but the associations between central or peripheral systolic blood pressure (SBP) changes and new‐onset hypertension are unclear. Annual changes in central and peripheral SBP over a mean interval of 2.36 years were calculated for 815 Chinese community residents without cardiovascular disease and hypertension at the first two visits, with the formula: ([2nd SBP−1st SBP]/1st SBP) × 100%/time interval (years). The independent and joint associations of these SBP changes with new‐onset hypertension at the third visit were assessed with multivariable logistic regression models. During a mean follow‐up interval of 4.37 years since the second visit, 171 new cases of hypertension were observed. Central and peripheral SBP changes were significantly associated with new‐onset hypertension (central SBP change rate: odds ratio [OR]: 1.19 [95% confidence intervals (CI) 1.13, 1.26]; peripheral SBP change rate: OR: 1.25 [95% CI 1.17, 1.33]), even after adjusting for each other. Compared to the group with neither SBP increased, the group with both SBPs increased showed a significantly higher risk of new‐onset hypertension (OR: 4.52 [95% CI 2.54, 8.04]). The model including both SBP changes had a higher area under the curve (AUC) for predicting hypertension in receiver operating characteristic (ROC) analyses than those with either change alone. Central and peripheral SBP changes are independently and jointly associated with new‐onset hypertension. It is recommended to regularly monitor both central and peripheral blood pressures.

Background: Partially driven by public concerns about modern food production practices, organic food has gained popularity among consumers. However, the impact of organic food consumption during pregnancy on offspring health is scarcely studied. We aimed to investigate the association between maternal intake of organic food during pregnancy and symptoms of attention deficit/hyperactivity disorder (ADHD) and autism spectrum disorder (ASD) in offspring at 8 years of age. Methods: This study was based on the Norwegian Mother, Father and Child Cohort Study (MoBa) and the Medical Birth Registry of Norway (MBRN). The total study sample included 40,707 mother–child pairs (children born 2002–2009). Organic food consumption during pregnancy was assessed by six questions from a food frequency questionnaire in mid-pregnancy (sum score 0–18). Symptoms of ADHD and ASD in the offspring aged 8 years were measured by ADHD (0–54) and ASD (0–39) symptom scores based on the Parent/Teacher Rating Scale for Disruptive Behaviour disorders and the Social Communication Questionnaire. Associations between maternal intake of organic food during pregnancy and symptoms of ADHD and ASD in the offspring were analyzed using regression models with adjustment for covariates such as maternal anxiety and depression, including sibling analysis. Results: Mean ADHD and ASD symptom scores in the offspring differed only slightly by maternal intake of organic food. The covariate-adjusted unstandardized regression coefficient (adjusted(Adj)beta) with 95% confidence interval for the ADHD symptom score with one unit increase in organic food sum score was 0.03 (0.01, 0.05). Similarly, Adjbeta for autism symptom score was 0.07 (0.04, 0.10). For ADHD, the adjusted estimates weakened when adjusting for maternal symptoms of ADHD. The sibling analyses showed no significant results with Adjbeta − 0.07 (− 0.15, 0.01) and − 0.001 (− 0.12, 0.12) for ADHD and ASD outcomes, respectively. Conclusions: We observed weak positive associations between frequent maternal organic food consumption during pregnancy and offspring ADHD and ASD symptom levels at 8 years of age. This trend weakened or disappeared after adjusting for maternal symptoms of ADHD, and in sibling analyses, suggesting that the associations mainly reflect genetic confounding. Our study indicates that consumption of organic food during pregnancy should neither be considered a risk factor nor protective against symptoms of ADHD and ASD in offspring. [ABSTRACT FROM AUTHOR]

The article discusses the development and validation of a new method for evaluating multiple islet autoantibodies in dried blood spots, specifically designed for pediatric screening programs. The study is part of a national screening program in Italy for type 1 diabetes and celiac disease. The method aims to improve the acceptability and efficiency of screening procedures by using a simple and stable sample collection technique. The results show that the new method is comparable to traditional tests and offers a reliable and convenient alternative for population screening programs, with good sensitivity and specificity.

Background and Aim Materials and Methods Results Conclusion Vitamin K deficiency is common in persons with kidney disease, which is a known complication of diabetes. We aimed to assess the association of vitamin K status as reflected by plasma dephosphorylated‐uncarboxylated matrix Gla protein (dp‐ucMGP) with mortality, cardiovascular disease (CVD) and progression to end‐stage kidney disease (ESKD) in persons with type 1 diabetes.We analysed plasma dp‐ucMGP in stored baseline samples from a cohort of 667 persons with type 1 diabetes (baseline visit: 2009–2011). Information on mortality and CVD was obtained through linkage to registers. Cox‐proportional hazards models were applied to estimate hazard ratios (HRs) of mortality, CVD and ESKD per one doubling of dp‐ucMGP.A total of 53 deaths were recorded during follow‐up. Persons with higher dp‐ucMGP (reflecting lower vitamin K status) had higher mortality in the unadjusted model (HR: 2.06 [95% confidence interval—CI: 1.22–3.45]), but not in the fully adjusted model (HR: 0.88 [95% CI: 0.44–1.73]). Particularly, adjustment for glomerular filtration rate and urinary albumin excretion rate attenuated the HR. A similar pattern was observed in unadjusted models for incidence of CVD (HR: 1.58 [95% CI: 1.03–2.42]) and risk of ESKD (HR: 7.62 [95% CI: 4.25–13.68]). In the fully adjusted models, the HRs became statistically insignificant.In persons with type 1 diabetes, lower vitamin K status was associated with higher mortality, CVD and progression to ESKD, however, not after adjustment for other risk factors. Interventional studies are needed to elucidate the role of vitamin K in persons with type 1 diabetes. [ABSTRACT FROM AUTHOR]

Introduction: Excessive abdominal adiposity represents a cardiovascular disease risk factor. Waist circumference (WC) reflects abdominal adiposity and is known as an easy-to-measure indicator of obesity. This study aimed to evaluate the relationship between WC level and the development of cerebral infarction in Koreans. Methods: 209,442 Koreans were included among the general population registered in the National Health Information Database. Depending on the degree of WC, the possibility of cerebral infarction was tracked for 4.37 personyears. Identification of patients with cerebral infarction was confirmed through the diagnostic code ICD I63 of inpatient or outpatient. Participants' data were analyzed by sex. The hazard ratios (HRs) and confidence interval (CI) for cerebral infarction were calculated using the Cox proportional hazards model. Results and discussion: Between 2009 and 2013, 2,403 cases (1.15%) of cerebral infarction occurred during the follow-up period of 915,223.6 person-years. The HRs (95% CI) for incident cerebral infarction in men was adjusted for multiple covariates, and comparison of WC levels second, third, and fourth quartile with the first quartile showed 1.10 (0.94-1.28), 1.11 (0.95-1.30), and 1.24 (1.07-1.45), respectively (P for trend 0.045). This association was not significant in women (P for trend 0.619). The severity of WC levels in men is significantly associated with the risk of developing cerebral infarction in Koreans. This finding indicates that other measurements for excessive adipose visceral tissue, except abdominal circumference, need to be taken into account to identify the risk of cerebral infarction in women.

Background: Uric acid closely relates to both kidney disease and atrial fibrillation (AF), yet the extent to which it influences the kidney-AF association remains uncertain. We examined the relationship between kidney function and risk of AF, accounting for uric acid levels. Methods: A total of 308,509 individuals in the Swedish Apolipoprotein-Related Mortality Risk (AMORIS) cohort were included and their serum creatinine and uric acid were measured during 1985–1996. Ten-year incident AF was identified via linkage with the national registers. Glomerular filtration rate (eGFR) (ml/min/1.73 m2) was calculated with the 2009 Chronic Kidney Disease Epidemiology Collaboration equation. Hyperuricemia was defined as > 420 µmol/L for men and > 360 µmol/L for women. Results: Over a mean follow-up of 9.4 years, 10,007 (3.2%) incident AF cases occurred. After adjusting for age, sex, cardiovascular diseases, total cholesterol, triglycerides, and glucose, individuals with low eGFR (< 30 and 30–59 ml/min/1.73 m2) had a higher risk of AF compared to those with normal eGFR (60–89) (hazard ratio (HR) = 1.72, 95% confidence interval (CI):1.29–2.30; HR = 1.10, 95% CI: 1.03–1.18, respectively). After further adjusting for uric acid levels, the association disappeared (HR = 0.97, 95% CI: 0.72–1.30; HR = 0.93, 95% CI: 0.86-1.00, respectively). When stratifying by hyperuricemia yes/no, eGFR < 30 ml/min/1.73 m2 was associated with higher AF risk in a small group of individuals without hyperuricemia (HR = 2.58, 95% CI: 1.64–4.07). Conclusion: Uric acid largely accounted for the relationship between eGFR and AF in this study. However, in individuals without hyperuricemia, eGFR in the lowest range (< 30 ml/min/1.73 m2) was still associated with increased risk of AF. [ABSTRACT FROM AUTHOR]

Background: Loneliness has garnered significant attention globally, with extensive exploration of its association with cardiovascular disease. However, a notable research gap persists concerning loneliness and its potential link to atrial fibrillation (AF). Methods: This prospective cohort study utilized data from the UK Biobank (UKB), encompassing 441,056 participants. Loneliness was assessed through self-reported questionnaires gauging feelings of isolation and willingness to confide. AF diagnoses were ascertained using hospitalization records and cause-of-death registry data. The association between loneliness and AF risk was analyzed through multivariable Cox proportional hazard models. Results: Over a median follow-up period of 13.9 years, 25,386 AF cases were identified. In comparison to individuals without reported loneliness, those in the loneliness group exhibited a significantly higher risk of AF (loneliness vs. non-loneliness: hazard ratio [HR]: 1.11, 95% confidence interval [CI] 1.07–1.16). Subgroup analysis revealed that the association between loneliness and increased AF risk was significant solely in individuals without heart valve disease (HR: 1.12, 95% CI 1.07–1.16). Additionally, significant associations between loneliness and heightened AF risk were noted across strata of genetic susceptibility to AF, with no observable impact on these associations by genetic susceptibility (P for interaction = 0.070). Conclusions: This study establishes a robust association between loneliness and an elevated long-term risk of AF. Notably, this association is particularly pronounced in individuals without valvular disease and does not appear to be influenced by genetic predisposition to AF. [ABSTRACT FROM AUTHOR]

Background: The pan-immune-inflammation value (PIV) is an emerging biomarker quantitatively reflecting the systemic immune-inflammatory status. The predictive value of PIV has been well-established across various clinical settings. However, its role in chronic obstructive pulmonary disease (COPD) remains unclear and necessitates further investigation. Methods: Data from NHANES 1999-2018 were filtered. Logistic regression analyses were used to assess the correlation between COPD prevalence and PIV in all participants. COX regression analyses and Kaplan-Meier survival curves were used to investigate the relationship between COPD all-cause mortality and PIV in COPD patients. Restricted cubic spline (RCS) analyses and piecewise linear regression analyses were additionally employed to explore the correlation between PIV and COPD. Subgroup analyses were performed to further clarify the effects of other covariates on the associations. Sensitivity analyses were employed to assess the robustness of the results. Results: A total of 28,485 participants aged 40 years and older were recruited for this study. After fully adjusting for covariates, higher PIV levels were independently associated with increased COPD prevalence (OR = 1.67; 95% CI: 1.39-2.01) and all-cause mortality (HR = 2.04; 95% CI: 1.41-2.95). The COPD prevalence curve exhibited an inflection point at Log10-PIV of 2.24, showing no significant correlation on the left side (OR = 0.86; 95% CI: 0.45-1.64) but a positive correlation on the right side (OR = 2.00; 95% CI: 1.57-2.55). The COPD allcause mortality curve displayed an inflection point at Log10-PIV of 2.38, indicating a negative correlation on the left side (HR = 0.23; 95% CI: 0.12-0.44) and a positive correlation on the right side (HR = 4.12; 95% CI: 2.62-6.48). Subgroup analyses with interaction tests showed that the strength of the correlation between PIV and COPD prevalence was influenced by race, smoking status, and BMI (all p for interaction <0.05). The relationship between PIV and COPD all-cause mortality was unaffected by any covariates (all p for interaction >0.05). Conclusion: Elevated PIV levels are associated with increased COPD prevalence. COPD patients with either elevated or reduced PIV levels experience higher allcause mortality. Further large-scale, longitudinal studies are required to corroborate these findings. [ABSTRACT FROM AUTHOR]

Background: Social isolation is a significant public health concern in aging societies. The association between conversation time and social behavior remains unclear. This study examines whether objective conversation time is associated with social activity frequency in older adults. Methods: This prospective cohort study enrolled 855 older adults (538 women; mean age, 73.8 years) aged 65 and older, who were followed from 2015 to 2019. All participants wore a wristband sensor to measure conversation time for at least 9 days and an average of 31.3 days per year. Social behaviors were assessed through interviews, and the frequency of engagement in community activities, outings, lessons, or classes and contact frequency were assessed using a self-report questionnaire. The association between conversation time and social behavior was evaluated using multi-linear regression analysis. Results: Conversation time was significantly associated with the frequency of engagement in community activities and lessons or classes after adjusting for several covariates (β = 0.181, 95% confidence interval: 0.107-0.254, p < 0.001; β = 0.11, 95% confidence interval: 0.04-0.179, p = 0.002). Conclusion: Objectively measured conversation time using a wearable sensor is associated with social behavior and may be a valuable parameter for social isolation in older adults.

Background: Several recent studies reported the potential adverse effects of titanium exposure on glucose homeostasis among the non-pregnant population, but the association of titanium exposure with gestational diabetes mellitus (GDM) is scarce. Methods: The present study of 1,449 pregnant women was conducted within the Jiangsu Birth Cohort (JBC) study in China. Urine samples were collected in the early pregnancy, and urinary titanium concentration and non-targeted metabolomics were measured. Poisson regression estimated the association of titanium exposure in the early pregnancy with subsequent risk of GDM. Multiple linear regression screened for titanium-related urine metabolites. Mediation analyses assessed the mediating effects of candidate metabolites and pathways. Results: As parameterized in tertiles, titanium showed positive dose–response relationship with GDM risk (P for trend = 0.008), with women at the highest tertile of titanium exposure having 30% increased risk of GDM [relative risk (RR) = 1.30 (95% CI: 1.06, 1.61)] when compared to those exposure at the first tertile level. Meanwhile, we identified the titanium-related metabolites involved in four amino acid metabolic pathways. Notably, the perturbation of the aminoacyl-tRNA biosynthesis and alanine, aspartate and glutamate metabolism mediated 27.1% and 31.0%, respectively, of the relative effect of titanium exposure on GDM. Specifically, three titanium-related metabolites, choline, creatine and L-alanine, demonstrated predominant mediation effects on the association between titanium exposure and GDM risk. Conclusions: In this prospective study, we uniquely identified a correlation between early pregnancy titanium exposure and increased GDM risk. We unveiled novel insights into how perturbations in amino acid metabolism may mediate the link between titanium exposure and GDM. Notably, choline, creatine, and L-alanine emerged as key mediators influencing this association. Our findings imply that elevated titanium exposure in early pregnancy can lead to amino acid dysmetabolism, thereby elevating GDM risk. [ABSTRACT FROM AUTHOR]

Objective: The aim of this study was to develop and validate a machine learningbased model to predict the development of impaired fasting glucose (IFG) in middle-aged and older elderly people over a 5-year period using data from a cohort study. Methods: This study was a retrospective cohort study. The study population was 1855 participants who underwent consecutive physical examinations at the First Affiliated Hospital of Soochow University between 2018 and 2022. The dataset included medical history, physical examination, and biochemical index test results. The cohort was randomly divided into a training dataset and a validation dataset in a ratio of 8:2. The machine learning algorithms used in this study include Extreme Gradient Boosting (XGBoost), Support Vector Machines (SVM), Naive Bayes, Decision Trees (DT), and traditional Logistic Regression (LR). Feature selection, parameter optimization, and model construction were performed in the training set, while the validation set was used to evaluate the predictive performance of the models. The performance of these models is evaluated by an area under the receiver operating characteristic (ROC) curves (AUC), calibration curves and decision curve analysis (DCA). To interpret the best-performing model, the Shapley Additive exPlanation (SHAP) Plots was used in this study. Results: The training/validation dataset consists of 1,855 individuals from the First Affiliated Hospital of Soochow University, yielded significant variables following selection by the Boruta algorithm and logistic multivariate regression analysis. These significant variables included systolic blood pressure (SBP), fatty liver, waist circumference (WC) and serum creatinine (Scr). The XGBoost model outperformed the other models, demonstrating an AUC of 0.7391 in the validation set. Conclusions: The XGBoost model was composed of SBP, fatty liver, WC and Scr may assist doctors with the early identification of IFG in middle-aged and elderly people. [ABSTRACT FROM AUTHOR]

Purpose: Cancer survivors encounter significant psychological suffering and are prone to develop depressive symptoms. Work contributes to personal fulfillment and social connections, and by doing so, enhances a cancer survivor's resilience against adversities. However, maintaining employment can be challenging for some cancer survivors. This research aimed to identify the association between changes in work status and depressive symptoms among cancer survivors in South Korea. Methods: This study used the panel data from the Korean Longitudinal Study of Ageing (KLoSA) and included 199 cancer survivors–799 observations–aged 65 or younger, between 2005 and 2018. Changes in work status consisted of continuous unemployment or employment, quitting a job, and getting a job. We defined depressive symptoms as a CES-D-10 score of 10 or higher and a cut-off of 4 was utilized for sensitivity analysis. Multivariable generalized estimating equation was employed to estimate the odds ratio (OR), adjusting for the number of household members, education level, sex, age, marital status, occupations, cancer treatment, cancer type, catastrophic healthcare expenditure (CHE), and survivorship. Subgroup analysis and interaction between changes in work and cancer types were further explored. Results: For depressive symptoms, the OR of the continuous unemployment group was 2.27 (95% CI = 1.10–4.69), and the OR of the group that quit a job was 2.20 (95% CI = 1.03–4.72), compared to the continuous employment group. As survivorship increased, the odds of depressive symptoms decreased (OR = 0.94, 95% CI = 0.89–1.00). CHE was associated with depressive symptoms (OR = 2.23, 95% CI = 1.18–4.20). In cancer types with a low tendency to depression, continuous unemployment was associated with depressive symptoms (OR = 3.19, 95% CI = 1.12–9.06). In sensitivity analysis, changes in work, survivorship, and CHE were consistently associated with depressive symptoms. Conclusions: Cancer survivors who quit a job or continued unemployment were more likely to experience depressive symptoms. The findings of this study imply that assistance for cancer survivors to continue a job or return to employment, including adjustment of workload and hours, may be helpful. Psychological care may be crucial, particularly in the early stage of cancer survivorship. Furthermore, support may be needed to alleviate the burden of healthcare expenditure.

Background: Gaucher’s disease (GD), a lysosomal storage disorder, poses significant treatment challenges. This 23-year study assesses survival rates and treatment efficacy in Brazilian GD patients, integrating data from a 16-year cohort (2000–2015) and the TABNET/DATASUS medicines distribution data (1999–2022). Objective: To investigate the survival of GD patients in Brazil, identifying key risk factors and evaluating the impact of treatments funded by the Brazilian National Health System (SUS). Methodology: A 16-year retrospective cohort study was conducted using the National Database of SUS. Patients diagnosed with GD and treated with Enzyme Replacement Therapy (ERT) or Substrate Synthesis Inhibition (SSI) from 2000 to 2015 were included. Survival analysis was performed using Kaplan-Meier method and Cox proportional hazards model. The data from TABNET/DATASUS system from 1999 to 2022 was used to assess the trend in drug distribution beyond the main cohort. Results: The study included 1,234 patients. Survival rates at 5 and 10 years were 93.2% and 88.5%, respectively, with age and comorbidities like diabetes, cardiovascular diseases, and Parkinson’s disease significantly affecting survival. Patients who received doses lower than DDD (n = 880) demonstrated a survival probability of 91.8%. In contrast, those with doses equal to the DDD (n = 15) showed a 100% survival probability, as no events were observed in this group. The greater than DDD group (n = 339) exhibited a survival probability of 81%. A logrank test indicated a borderline statistical significance (p = 0.058) in the survival distributions among the different DDD adherence, with the lower dose group showing a favorable trend. Conclusion: This study provides insights into the survival rates and associated risk factors for GD patients in Brazil, contributing to the global understanding of GD and its management. While we acknowledge the inherent limitations of relying largely on electronic medical records and categorical codes, our findings underscore the need for early diagnosis, timely initiation of treatment, effective management of comorbidities, and personalized dosing strategies to improve patient outcomes. Future studies should aim to incorporate clinical verification of electronic data to further enhance the reliability and applicability of these findings. [ABSTRACT FROM AUTHOR]

Previous studies have yielded inconsistent results regarding the association between chronic kidney disease (CKD) and the risk of cognitive impairment (CI). This study aimed to investigate the longitudinal association of CKD with CI risk in the Chinese middle-aged and older population. A total of 16,515 CI-free participants 45 years of age or older including 15,595 without CKD and 920 with CKD were followed from 2011 until 2018 (median [interquartile range]: 7 [5.5-7]) to detect incident CI. Over the follow-up, 648 participants developed CI. Data were analyzed using multi-adjusted Cox proportional hazard regression and Laplace regression. The incidence rate (IR) of CI was significantly higher in individuals with CKD at 11.46 per 1,000 person-years (95% confidence interval [CI], 8.90 to 14.76) than in those without CKD at 6.38 per 1,000 person-years (95% CI, 5.89 to 6.92). Compared to those without CKD, the hazard ratios of those with CKD was 1.56 (95% CI, 1.19 to 2.04) for CI. Participants with CKD in the middle-aged group (45–54 years) exhibited a heightened risk of CI in age-stratified analyses. CKD accelerated the onset of CI by 1.24 years (10th percentile difference [PD]; 95% CI, -2.03 to -0.43, p < 0.01). The findings from this study revealed a significantly increased risk of CI in individuals with CKD, especially in middle-aged population, where the risk appeared to be more pronounced. This observation underscores the importance of early detection and intervention strategies to alleviate the potential cognitive decline associated with CKD. [ABSTRACT FROM AUTHOR]

Background: At the beginning of the COVID-19 pandemic, some workers had the opportunity to work from home, while others remained in on-site work. The aim of the present study was to compare the psychosocial work aspects, work ability, mental health conditions and SARS-CoV-2 infection rates of Brazilian workers in remote and on-site work through a longitudinal study with quarterly follow-up assessments over a 12-month period. Method: A convenience sample of 1,211 workers from different economic sectors participated in the study, 897 of whom (74.1%) worked from home and 314 (25.9%) remained in on-site work. Psychosocial work aspects were assessed using the Copenhagen Psychosocial Questionnaire (COPSOQ). Work ability was assessed using the Work Ability Index (WAI) and the Work Ability Score (WAS). Mental health conditions and SARS-CoV-2 infection rate were recorded based on self-reported medical diagnoses. Online questionnaires were answered from June 2020 to September 2021, involving two waves of the COVID-19 pandemic. The groups were compared using chi-square tests, t-tests, and two-way ANOVA. Results: In the first wave of the pandemic, remote workers reported more quantitative demands and work-family conflicts, whereas on-site workers reported more emotional demands, low development of new skills, low commitment, low predictability, low recognition, and low satisfaction. They also reported greater occurrences of unwanted sexual attention, threats of violence, and physical violence. In the second wave, the remote group continued to report high work-family conflicts, whereas the on-site group reported – in addition to the results of the 1st wave – low influence at work, low quality of leadership, and burnout. No significant difference was found between groups with regards to the WAI in either wave. A significant difference was found for the WAS between the 3rd and 12th months (P < 0.01) in both groups. No significant differences were found between groups for the prevalence of anxiety, depression, burnout/stress, insomnia, panic syndrome, and eating disorders, except for the prevalence of insomnia at the 12-month follow-up, with higher rates in the remote group (P = 0.03). SARS-CoV-2 infection was significantly lower in the remote group (11.3%) compared to the on- site (16.9%) group (P < 0.01). Conclusions: Psychosocial work aspects differed between remote and on-site workers. Work ability and mental health conditions were similar between groups. Remote work might have played a role in limiting the spread of the virus in Brazil had it been more widely available. [ABSTRACT FROM AUTHOR]

Background: Urinary incontinence is frequent in the general population and affects men and women of all ages. UI carries an unsuspected load on the healthcare system. To investigate whether urinary incontinence is associated with all-cause, cardiovascular disease (CVD) and cancer mortality among US adults. Methods: The analyzed data was collected from the 2007–2016 National Health and Nutrition Examination Survey (NHANES) data. A total of 25,182 US participants with complete information about follow-up information and urinary incontinence (UI) were included in this cohort study. Univariate Cox regression analyses, the UpSet plot, multivariate Cox regression analysis, subgroup analysis of all-cause mortality, and Kaplan-Meier survival curve were employed to support the research objectives. Results: A total of 25,182 participants had a mean age of 49.8 ± 17.8 years, with 49.3% of them being male and 50.7% of them being female. In the unadjusted model, we found that the risk of all-cause mortality increased by 12% (95% CI 1.03–1.22, P = 0.008), the risk of CVD mortality increased by 21% (95% CI 1.07–1.36, P = 0.002), and the risk of Cancer mortality increased by 8% (95% CI 0.95–1.22, P = 0.243) among individuals with urinary incontinence. After adjusting for multiple variables, we found that the risk of all-cause mortality in patients with urinary incontinence decreased by 1% (95% CI 0.9–1.09), but this decrease was statistically insignificant (P = 0.868), and the risk of Cancer mortality decreased by 3% (95% CI 0.84–1.12, P = 0.686). The association between urinary incontinence and mortality risk were stable in stratified analyses. Conclusions: In our study, we found that urinary incontinence itself is an independent risk factor for death. The association between urinary incontinence and mortality became less significant after adjusting for covariates, this is a common occurrence in statistical analysis. Future research, with larger sample sizes and more robust study designs, is needed to further elucidate the complex relationship between urinary incontinence and mortality risk.

ABSTRACT Objectives Methods Results Conclusion To investigate whether timing, accumulation and trajectories of poverty are associated with dental caries in young adolescents.The study was conducted within the Generation R Study, which is an ongoing population‐based prospective cohort study conducted in Rotterdam, the Netherlands. This study included 2653 children. Information about household income and number of children and adults living in a household at six time points from pregnancy to 13 years old was retrieved from parental questionnaires to construct the poverty variable. Dental caries was assessed with the decayed, missing and filled teeth index through intraoral photographs at the age of 13 years. Sociodemographic and oral health‐related characteristics were included as possible confounders. The association between poverty and dental caries was analysed on the basis of the three lifecourse theories, that is, critical period, cumulative risk and social mobility model. For the latter, we used latent class growth analysis (LCGA) to identify poverty trajectories over time. Next, the associations were studied with Hurdle Negative Binomial Models.Poverty at birth and intermittent poverty up to the age of 13 were significantly associated with dental caries at 13 years of age (OR 1.41, 95% CI 1.01–1.99; OR 1.36, 95% CI 1.01–1.83 respectively) and with an increased mean number of decayed teeth by 34% (95% CI 1.02–1.76; 95% CI 1.05–1.71, respectively). LCGA showed four trajectories for the probabilities of poverty. All trajectories were significantly associated with dental caries at 13 years of age, with the ‘downward mobility’ trajectory showing the strongest association with dental caries (OR 1.55, 95% CI 1.05–2.29) and an increasing mean number of decayed teeth by 58% (95% CI 1.18–2.12) than the ‘stable absent’ trajectory.Poverty at birth, intermittent poverty and downward poverty trajectory were associated with higher odds and higher mean number of decayed teeth at 13 years of age. The three lifecourse models influenced dental caries status during adolescence, hence strategies and policies targeted to improve socioeconomic conditions on deprived children should be implemented.

Background: Post-viral symptoms have long been known in the medical community but have received more public attention during the COVID-19 pandemic. Many post-viral symptoms were reported as particularly frequent after SARS-CoV-2 infection. However, there is still a lack of evidence regarding the specificity, frequency and persistence of these symptoms in comparison to other viral infectious diseases such as influenza. Methods: We investigated a large population-based cohort based on German routine healthcare data. We matched 573,791 individuals with a PCR-test confirmed SARS-CoV-2 infection from the year 2020 to contemporary controls without SARS-CoV-2 infection and controls from the last influenza outbreak in 2018 and followed them up to 18 months. Results: We found that post-viral symptoms as defined for COVID-19 by the WHO as well as tissue damage were more frequent among the COVID-19 cohort than the influenza or contemporary control cohort. The persistence of post-viral symptoms was similar between COVID-19 and influenza. Conclusion: Post-viral symptoms following SARS-CoV-2 infection constitute a substantial disease burden as they are frequent and often persist for many months. As COVID-19 is becoming endemic, the disease must not be trivialized. Research should focus on the development of effective treatments for post-viral symptoms. [ABSTRACT FROM AUTHOR]

AbstractBackgroundMethodsFindingsConclusion\nHIGHLIGHTSThe objectives of this study were to investigate the relationship between perinatal risk factors and suicidal ideation and attempts in young adults in Pelotas, Brazil.The data were collected from the 1993 Pelotas Birth Cohort study. Every pregnant woman who gave birth in one of the hospitals in Pelotas Brazil in 1993 was invited to participate in the study. The current study uses perinatal data collected in 1993, and follow-ups at ages 18 and 22. The primary outcome was lifetime suicide attempts with past month suicide ideation a secondary outcome. The association between perinatal predictors and suicidal ideation or lifetime suicide attempts was investigated using hierarchical logistic regression.There was an analytic sample size of 3493. The perinatal factors association with lifetime suicide attempts were sex (OR = 2.25 CI: 1.76–2.89), paternal education at birth (OR = 0.60, 95%CI: 0.36–0.99), maternal education (9–11 years OR = 2.81, 95%CI: 1.41–5.59, & 0–8 years OR = 2.21, 95%CI: 1.07–4.58), support from friends or neighbors at birth (OR = 0.36 95%CI: 0.17–0.77), and maternal smoking during pregnancy (OR = 1.41, 95%CI: 1.10–1.79). Patterns of associations were broadly similar with suicidal ideation. Interactions between sex and the perinatal factors paternal education, maternal education, smoking and support from friends were assessed and found to be not significant.Several factors during the perinatal period are associated with risk of lifetime suicide attempts and ideation in young adults in Brazil. Early-life factors associated with suicide-related concerns in early adulthood were similar to those observed in studies from high-income settings.Perinatal factors associated with suicidal behaviour were determined using data from upper-middle income setting.Maternal education, and maternal smoking are associated with risk of lifetime suicide attempts.Perinatal factors associated with suicidal ideation were similar to those of suicide attempts, including sex, maternal education, and maternal smoking.Perinatal factors associated with suicidal behaviour were determined using data from upper-middle income setting.Maternal education, and maternal smoking are associated with risk of lifetime suicide attempts.Perinatal factors associated with suicidal ideation were similar to those of suicide attempts, including sex, maternal education, and maternal smoking.

Background: The associations of weight change with all-cause and cause-specific mortality stratified by age remains unclear. We evaluated the age-stratified (< 65 vs ≥ 65 years) associations of weight change with all-cause and cause-specific mortality in a large sample of Chinese adults. Methods: Our cohort study included 746,991 adults aged at least 45 years from the Shenzhen Healthcare Big Data Cohort in China. BMI change were categorized as change within 5% (stable), decrease by 5% to 10%, decrease by > 10%, increase by 5% to 10%, and increase by > 10%. Cox proportional hazard models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for all-cause, non-communicable disease, cardiovascular disease (CVD), and cancer mortality according to BMI change, with adjustment for potential confounders. Results: During a median follow-up of 2.2 years (2,330,180 person-years), there were 10,197 deaths. A notable interaction emerged between weight change and age. For participants ≥ 65 years, compared with stable BMI, more than a 10% decrease in BMI was associated with higher risk of all-cause mortality (HR: 1.69, 95% CI: 1.54–1.86), non-communicable disease mortality (HR: 1.67, 95% CI: 1.52–1.84), CVD mortality (HR: 1.55, 95% CI: 1.34–1.80), and cancer mortality (HR: 1.59, 95% CI: 1.33–1.92). Similar patterns of results for 5% to 10% decrease in BMI were observed. More than a 10% increase in BMI was associated with increased risk of all-cause mortality (HR: 1.13, 95% CI: 1.04–1.24), non-communicable disease mortality (HR: 1.14, 95% CI: 1.04–1.25), and CVD mortality (HR: 1.27, 95% CI: 1.12–1.44). For participants < 65 years, only more than a 10% decrease in BMI was associated with higher risk of all-cause mortality (HR: 1.41, 95% CI: 1.12–1.77), non-communicable disease mortality (HR: 1.43, 95% CI: 1.13–1.81), and cancer mortality (HR: 1.79, 95% CI: 1.29–2.47). Conclusions: Weight loss and excessive weight gain were associated with increased risks of mortality among older adults, while only excessive weight loss was associated with increased risks of mortality among middle-aged adults.

Objectives: This study examined the potential association between nucleated red blood cell (NRBC) levels and mortality in critically ill patients with acute pancreatitis (AP) in the intensive care unit, due to limited existing research on this correlation. Methods: This retrospective cohort study utilized data from the MIMIC-IV v2.0 and MIMIC-III v1.4 databases to investigate the potential relationship between NRBC levels and patient outcomes. The study employed restricted cubic splines (RCS) regression analysis to explore non-linear associations. The impact of NRBC on prognosis was assessed using a generalized linear model (GLM) with a logit link, adjusted for potential confounders. Furthermore, four machine learning models, including Gradient Boosting Classifier (GBC), Random Forest, Gaussian Naive Bayes, and Decision Tree Classifier model, were constructed using NRBC data to generate risk scores and evaluate the potential of NRBC in predicting patient prognosis. Results: A total of 354 patients were enrolled in the study, with 162 (45.8%) individuals aged 60 years or older and 204 (57.6%) males. RCS regression analysis demonstrated a non-linear relationship between NRBC levels and 90-day mortality. Receiver Operating Characteristic (ROC) analysis identified a 1.7% NRBC cutoff to distinguish survivor from non-survivor patients for 90-day mortality, yielding an Area Under the Curve (AUC) of 0.599, with a sensitivity of 0.475 and specificity of 0.711. Elevated NRBC levels were associated with increased risks of 90-day mortality in both unadjusted and adjusted models (all Odds Ratios > 1, P < 0.05). Assessment of various machine learning models with nine variables, including NRBC, Sex, Age, Simplified Acute Physiology Score II, Acute Physiology Score III, Congestive Heart Failure, Vasopressin, Norepinephrine, and Mean Arterial Pressure, indicated that the GBC model displayed the highest predictive accuracy for 90-day mortality, with an AUC of 0.982 (95% CI 0.970–0.994). Post hoc power analysis showed a statistical power of 0.880 in the study. Conclusions: Elevated levels of NRBC are linked to an increased mortality risk in critically ill patients with AP, suggesting its potential for predicting mortality. [ABSTRACT FROM AUTHOR]

Objective: The long-term glucose monitoring is essential to the risk assessment of diabetic retinopathy (DR), the aim of this study was to investigate the predictive ability of visit-to-visit fasting blood glucose (FBG) indices on the risk of DR. Methods: This was a community-based, cohort study conducted from 2013 to 2021. DR was diagnosed by digital fundus photography. The FPG indices included FBG, var. Associations of each FBG indices and DR were estimated using multinomial logistic regression models adjusting for confounders, and discrimination was determined by area under the curve (AUC). Predictive utility of different models was compared by changes in AUC, integrated discrimination improvement (IDI), and net reclassification index (NRI). Results: This study analyzed 5054 participants, the mean age was 46.26 ± 11.44 years, and 2620 (51.84%) were women. After adjustment for confounders, the adjusted odds ratios (ORs) with 95% confidence intervals (CIs) for FBG, SD, CV, VIM, ARV, M-FBG, and cumulative FBG load were 1.62 (1.52-1.73), 2.74 (2.38-3.16), 1.78 (1.62-1.95), 1.11 (0.95-1.29), 1.72 (1.56-1.91), 2.15 (1.96-2.36), and 2.57 (2.31-2.85), respectively. The AUC of the model with separate cumulative FBG load and classical risk factors was 0.9135 (95%CI 0.8890-0.9380), and no substantive improvement in discrimination was achieved with the addition of other FBG indices once cumulative FBG load was in the model. Conclusions: Cumulative FBG load is adequate for capturing the glucose-related DR risk, and the predictive utility of cumulative FBG load is not significantly improved by adding or replacing other FBG indices in the assessment of DR risk.

Objective: The incidence of work-related falls on the same level is increasing, particularly among middle-aged and older female workers. Vision is an important risk factor of falls. We investigated whether objectively measured visual acuity was associated with the incidence of falls. Methods: This cohort study included 7317 female employees aged 20-69 in Japanese supermarket stores. Monocular acuity measured during health checkups was classified into three levels (=0.7, 0.3-0.7, <0.3). Incidence rate ratios of work-related falls within 1 year were estimated. Results: Incidence rate ratios were 1.26 (95%CI: 0.92-1.72) in the 0.3-0.7 group and 2.27 (95%CI: 1.15-4.48) in the <0.3 group. Conclusions: Risk of work-related fall was higher in those with low visual acuity. Vision correction may contribute to fall prevention in workplaces. [ABSTRACT FROM AUTHOR]

Objective: We hypothesized that telecommuting's impact on sleep varied based on preference-frequency mismatch. Here, we evaluated this relationship in a large cohort of Japanese workers. Methods: We collected data from 33,302 Japanese workers through an online survey and analyzed participant preferences and frequency of telecommuting in 9425 individuals who responded to a follow-up survey. We evaluated sleep using the Athens Insomnia Scale and estimated odds ratios of insomnia using multilevel logistic regression. Results: Workers preferring telecommuting had a higher risk of insomnia as telecommuting frequency decreased. OR for insomnia was 1.87 (P < 0.001) in those who telecommuted less than once per week. Conclusion: Telecommuting's impact on workers' sleep depends on preference mismatch, with a higher risk of insomnia among those who prefer telecommuting but are unable to utilize it.

Aims: The safety and efficacy of insulin analogue insulin aspart (IAsp) have been demonstrated in a randomised clinical trial in pregnant women with Type 1 diabetes (T1D), and IAsp is widely used during pregnancy. The aim of this study was to assess glycaemic control and safety of IAsp versus other bolus insulins in Type 1 diabetic pregnancy in a real‐world setting. Methods: This was a post hoc analysis of a prospective cohort study of 1840 pregnant women with T1D, treated with IAsp (n = 1434) or other bolus insulins (n = 406) in the Diabetes Pregnancy Registry. The primary (composite) outcome was the proportion of pregnancies resulting in major congenital malformations or perinatal or neonatal death. Secondary outcomes included all HbA1c values measured immediately before and during pregnancy and major hypoglycaemia, as well as abortion, pre‐eclampsia, pre‐term delivery, large for gestational age at birth, stillbirth and fetal malformations. Results: There were no significant differences found in any of the pregnancy outcomes between treatment with IAsp and other bolus insulins in either the crude or propensity score‐adjusted analyses. However, maternal HbA1c was lower in the IAsp group at the end of the third trimester (adjusted difference, −0.16% point [95% CI −0.28;−0.05]; −1.8 mmol/mol [95% CI −3.1;−0.6]; p = 0.0046). Conclusions: No significant differences in safety or pregnancy outcomes were demonstrated when comparing treatment with IAsp versus other bolus insulins in women with T1D during pregnancy. The observed improvement in HbA1c with IAsp in late pregnancy should be confirmed in other studies. [ABSTRACT FROM AUTHOR]

Background and hypothesis Evidence on the role of smoking in the development of chronic kidney disease (CKD) has mostly relied on self-reported smoking status. We aimed to compare the associations of smoking status as assessed by self-reports and urine cotinine with CKD risk. Methods Using the PREVEND prospective study, smoking status was assessed at baseline using self-reports and urine cotinine in 4333 participants (mean age, 52 years) without a history of CKD at baseline. Participants were classified as never, former, light current, and heavy current smokers according to self-reports and comparable cutoffs for urine cotinine. Hazard ratios (HRs) with 95% confidence intervals (CIs) were estimated for CKD. Results The percentages of self-reported and cotinine-assessed current smokers were 27.5% and 24.0%, respectively. During a median follow-up of 7.0 years, 593 cases of CKD were recorded. In analyses adjusted for established risk factors, the HRs (95% CI) of CKD for self-reported former, light current, and heavy current smokers compared with never smokers were 1.17 (0.95–1.44), 1.48 (1.10–2.00), and 1.48 (1.14–1.93), respectively. On further adjustment for urinary albumin excretion (UAE), the HRs (95% CI) were 1.07 (0.87–1.32), 1.26 (0.93–1.70), and 1.20 (0.93–1.57), respectively. For urine cotinine-assessed smoking status, the corresponding HRs (95% CI) were 0.81 (0.52–1.25), 1.17 (0.92–1.49), and 1.32 (1.02–1.71), respectively, in analyses adjusted for established risk factors plus UAE. Conclusion Self-reported current smoking is associated with increased CKD risk, but dependent on UAE. The association between urine cotinine-assessed current smoking and increased CKD risk is independent of UAE. Urine cotinine-assessed smoking status may be a more reliable risk indicator for CKD incidence than self-reported smoking status. [ABSTRACT FROM AUTHOR]

Background: When it comes to women with malignant gynecological tumor diagnosis, ovarian cancer (OC) is the most prevalent cause of death. Generally, it ranks as the fifth most common cause of mortality for females. Objectives: The present study aimed to study the epidemiological characteristics and treatment outcomes of OC cases in the Clinical Oncology and Nuclear Medicine Department at Zagazig University Hospitals. Methods: This retrospective cohort study targeted seven years from January 2015 to December 2021 and was conducted on 160 medical files of patients with OC from the Clinical Oncology and Nuclear Medicine Department, Zagazig University hospitals. The data of pathological and epidemiological characters and their outcomes were studied. Results: 66.9% of the studied patients had surgery upfront. The most frequent surgery types were TAH + BSO + Surgical staging (38.3%), TAH+BSO (29.4%), and Fertility-sparing surgery was reported in 7.9% of the cases. Regarding primary chemotherapy (95.6%) of patients had Primary chemotherapy as follows (2.5%) Neoadjuvant treatment only, (45%) Adjuvant only, (23.7%) had neoadjuvant and adjuvant, (4.4%) Definitive, and (20%) Palliative treatment. Regarding Hormonal treatment; (6.9%) of patients had Hormonal treatment as follows (1.9%) Adjuvant, (1.3%) Definitive, and (3.7%) salvage for Recurrence. There was a highly significant decrease in all Survival parameters (Local recurrence Free Survival, Regional recurrence Free Survival, Distant metastasis Free Survival, Disease-Free Survival, Progression Free Survival, and Overall survival) as regards an increase in age, Advanced disease & stage and ECOG PS 3, increase in Stage, and Epithelial tumors (p < 0.01 respectively). The mean survival time (MST) was significantly reduced in the advanced disease group compared to other clinical presentation groups. MST was significantly reduced in the ECOG-3 group compared to other ECOG PS groups. MST was significantly reduced in the distant metastasis group compared to other extension of disease groups. MST was significantly reduced in the stage IV group compared to other histopathology stage groups. MST was significantly reduced in the serious adverse effects group compared to the no serious adverse effects group. Conclusion: This study demonstrates that age as an important epidemiological factor, histopathological finding assessment, surgical status, radiological, location, grading, tumor morphology, treatment, outcome, recurrence of tumor, disease-free survival, and overall survival that was collected from patient archives in Clinical Oncology and nuclear medicine department in Zagazig University Hospitals. Therefore, this data can provide preliminary information for upcoming research. [ABSTRACT FROM AUTHOR]

Most previous studies found an elevated risk of endometrial cancer among women with polycystic ovary syndrome (PCOS). However, these had highly varying methods for ascertainment of PCOS diagnoses and limitations such as few exposed women and short follow-up. In this cohort study, we investigated the association between PCOS and endometrial cancer among women born in Denmark between January 1, 1940, and December 31, 1993 (n  = 1 719 121). Data in this study, including PCOS and endometrial cancer diagnoses and covariates, were derived from nationwide registers. We used Cox proportional hazards regression models to calculate hazard ratios (HRs) and 95% CIs. A total of 7862 endometrial cancer cases were identified during 23.7 years of follow-up (IQR, 37.7-61.9). We found an increased risk of endometrial cancer among women with PCOS compared with women without PCOS (HR = 3.02; 95% CI, 2.03-4.49). The risk was increased for premenopausal women (HR = 5.82; 95% CI, 3.64-9.30), whereas no marked association was seen for postmenopausal women. However, for postmenopausal women, results were limited by few cases and young age at the end of follow-up.

To assess if the impacts of prenatal maternal stress (PNMS) on neonatal physical development including birth weight and body length vary by trimesters, and to explore the mediating effect of sleep quality in the relationships. A total of 2778 pregnant women were included from the Shanghai Maternal‐Child Pairs Cohort. PNMS and sleep quality were measured in the first trimester (12–16 gestational weeks) and third trimester (32–36 gestational weeks) using the Life Event Scale for Pregnant Women (LESPW) and Pittsburgh Sleep Quality Index, respectively. And total LESPW scores were classified into three groups: high stress (≥75th percentile), medium stress (≥25th and <75th percentile), and low stress (<25th percentile). Multiple linear and logistic regressions were employed to examine the associations between PNMS and birth weight, and bootstrap were utilized to explore the mediating effects of maternal sleep. Higher (adjusted odds ratio, aOR = 1.521; 95% confidence interval (CI), 1.104–2.096) and medium (aOR = 1.421; 95% CI, 1.071–1.885) PNMS and stress from subjective events (aOR = 1.334; 95% CI, 1.076–1.654) in the first trimester were significantly associated with elevated risk for large for gestational age. Maternal severe negative objective events stress (OE3) in the third trimester were negatively associated with birth weight (β = −0.667; 95% CI, −1.047∼−0.287), and maternal sleep latency during this period acted as a mediator in the association (indirect effect: β = −0.0144; 95% CI, −0.0427∼−0.0003). Besides, a significant negative correlation between total LESPW score (β = −0.022; 95% CI, −0.038∼−0.006; per 100 score) and body length in the third trimester was also observed. The impact of PNMS on neonatal birth weight varies by stress types and exposure timing. Prolonged maternal sleep latency in the third trimester correlated with lower birth weight, and mediating the link of OE3 and birth weight, which might indicate a critical period of vulnerability to the effects of PNMS on neonatal physical development.

Background: Population-based studies that examine the associations between hyperthyroidism and cancer risk have yielded inconsistent results. It remains unclear whether the risks of different cancers increase in patients with Graves' disease (GD) who received antithyroid drugs (ATDs) as initial treatment. We aimed to determine whether cancer risk increases in patients with GD, compared with controls. Methods: This nationwide retrospective cohort study utilized data from the National Health Information Database of South Korea. We included 29,502 patients aged >20 years with GD, who received ATDs as initial treatment, and 57,173 age- and sex-matched controls. The primary outcome was the incidence of various types of cancers. Hazard ratios (HRs) with confidence intervals (CIs) for cancer risk were estimated using Cox proportional hazards models. We also analyzed HR by follow-up period since the diagnosis of GD, accounting for surveillance effect. Results: The risk of biliary tract and pancreatic cancers (HR: 1.41, CI: 1.24–1.60), thyroid cancer (HR: 15.51, CI: 12.29–19.57), prostate cancer (HR: 1.48, CI: 1.28–1.71), and ovarian cancer (HR: 1.31, CI: 1.13–1.52) was elevated in the GD group than in the control group even after the first year of follow-up was excluded. The increased risk of these cancers persisted after a follow-up period of more than 5 years. The risk of thyroid cancer in patients with GD was higher during the initial follow-up period (1 to <2 years) (HR: 19.35, CI: 7.66–48.87) compared with that in the follow-up period exceeding 2 years. The cancer risk estimates remained significant after excluding patients with GD who underwent subsequent radioactive iodine therapy. Conclusion: In this large-scale population-based study, GD was associated with increased risks of biliary tract and pancreatic, prostate, ovarian, and thyroid cancers. The increased risk of thyroid cancer, particularly during the initial follow-up period, may be a surveillance effect. [ABSTRACT FROM AUTHOR]

Background Methods Results Conclusions Previous research shows that obesity, unhealthy eating, physical inactivity and a high use of psychotropic medications are prevalent among persons with intellectual disability (ID), which might increase the risk of type 2‐diabetes (T2DM). This study aims to investigate: (1) whether persons with ID have an increased risk of T2DM compared with an age‐ and sex‐matched reference group and (2) differences in T2DM risk by sex, birth year, ID inclusion diagnosis and ID severity.This study is a nationwide cohort study, including 65 293 persons with ID and 659 723 persons in an age‐ and sex‐matched reference group without ID. Incidence rates for T2DM were calculated and Cox proportional regression models were used to estimate adjusted hazard ratios (aHRs) for the association between ID and T2DM. Follow‐up began from the 1 January 1977 (when T2DM data were available), participants' 22nd birthday or from the date the participants immigrated to Denmark, whichever came last and continued until the onset of T2DM, emigration, death or end of follow‐up (31 December 2021), whichever came first.Persons with ID had more than double risk of T2DM compared with the reference group [aHR = 2.15, 95% confidence interval (CI): 2.09–2.20]. The strongest associations were found among women, persons born between 1980 and 1999 and among persons with mild ID.Persons with ID have an increased risk of T2DM. This knowledge is important in relation to the development and prioritising of preventive initiatives among persons with ID in the healthcare sector. Future research should focus on the underlying mechanisms that can explain the possible association between ID and T2DM as it allows a more targeted prevention strategy. [ABSTRACT FROM AUTHOR]

Aim Methods Results Conclusions Our study aimed to evaluate the association between the metabolic score for visceral fat (METS‐VF) and mortality.We conducted a cohort study comprising 11,120 participants. We employed weighted multivariable Cox regression analysis to assess the relationship between METS‐VF and mortality. Restricted cubic spline analyses were used to investigate potential non‐linear associations. Receiver operating characteristic curves were used to evaluate the predictive value of METS‐VF and other obesity‐related indicators for mortality. Subgroup analysis and sensitivity analysis were performed to confirm the robustness of the results. Mendelian randomization analysis was utilized to assess potential causality.Over a median follow‐up duration of 83 months, a total of 1014 all‐cause deaths, 301 cardiovascular deaths, and 262 cancer deaths occurred. For every 0.2‐unit increase in METS‐VF, the hazard ratios(HRs) of all‐cause mortality, cardiovascular mortality, and cancer mortality were 1.13 [95% confidence interval (CI): 1.06, 1.20], 1.18 (95% CI: 1.06, 1.31), and 1.13 (95% CI: 1.03, 1.25), respectively. In addition, restricted cubic spline analyses revealed no significant non‐linear associations between METS‐VF and all‐cause mortality, cardiovascular mortality, and cancer mortality. In multivariate Cox regression models, hazard ratios of all‐cause mortality, cardiovascular mortality and cancer mortality were higher in the highest METS‐VF group compared to the reference group. Subgroup and sensitivity analyses confirmed that our results were robust. Receiver operating characteristic curves indicated that METS‐VF predicted mortality better than other obesity‐related indicators. Mendelian randomization analysis confirmed significant causal relationships.METS‐VF was positively associated with all‐cause mortality, cardiovascular mortality, and cancer mortality. These findings suggest that METS‐VF could serve as a straightforward, reliable, and cost‐effective marker for identifying individuals at high risk of mortality. [ABSTRACT FROM AUTHOR]

Purpose: Psychotic disorders are associated with substantial productivity costs; however no previous studies have compared these between schizophrenia spectrum (SSD) and other psychotic disorders (OP). The human capital method (HCM) and the friction cost method (FCM) are the two most common approaches to assess productivity costs. The HCM focuses on employees' perspectives on the costs, whereas the FCM demonstrates employers' perspectives. Studies comparing these methods when estimating the productivity costs of psychoses are lacking. Methods: Utilizing the Northern Finland Birth Cohort 1966 with linkages to national registers, we compared the adjusted productivity costs of SSD (n = 216) and OP (n = 217). The productivity costs were estimated from ages 18 to 53 including projections to statutory retirement age using the FCM and HCM. Results: When estimated via the HCM, productivity losses were higher for SSD (€193,940) than for OP (€163,080). However, when assessed using the FCM, costs were significantly lower for SSD (€2,720) than for OP (€4,430). Productivity costs varied by sex and various clinical and occupational factors. Conclusion: This study highlights how productivity costs vary by psychosis diagnosis. These differences should be noted when planning interventions. The low FCM estimates indicate the need of interventions before or during the early phases of psychoses. From a societal perspective, interventions are needed, particularly for those with highest HCM productivity losses, such as males with SSD. Besides psychiatric services, the roles of social services, employment agencies and occupational health care should be considered when helping individuals with psychoses to working life.

Background: Our study examines the rarely investigated associations between body dissatisfaction and educational level over the life course in women and men. Methods: A Finnish cohort (N = 1955) was followed by questionnaires at ages 22, 32, 42, and 52. Body dissatisfaction was measured by asking the respondents to evaluate their appearance using five response options. Analyses were done using logistic regression, while latent class analyses were used to identify classes of body dissatisfaction trajectories over the life course. Results: Body dissatisfaction increased with age in women and men. Among men, body dissatisfaction was related to lower education at the ages of 32 and 42. Also, men with lower education were more likely to maintain a less positive body image over the life course. In women, increasing body dissatisfaction during the life course was associated with lower education. Conclusions: Differences in body dissatisfaction based on educational level are important to take into account in public health actions aiming to reduce socioeconomic inequalities in health and well-being.

Background and aims: This study aimed to examine the cumulative effects of body mass index (BMI), body roundness index (BRI), pulse pressure (PP), triglycerides (TG), high-density lipoprotein cholesterol (HDL) and fasting plasma glucose (FPG) on Type 2 diabetes (T2D) morbidity. Methods: A total of 78,456 participants aged older than 45 years were extracted from basic public health services in China. During the 2-year follow-up, 6,942 individuals had developed T2D. The binary logistic regression models and multinomial logistic regression models were conducted to investigate the effects of cumulative metabolic parameters on incident T2D, prediabetes regression and progression. Results: We found statistically deleterious impacts of exposure to high cumulative BMI, BRI, PP, TG and low cumulative HDL on T2D morbidity and prediabetes progression. Compared to the group with low cumulative of all five parameters, the adjusted ORs for new-onset T2D for participants presenting with 1–2, 3, and 4–5 elevated metabolic parameters were 1.41(1.31,1.52), 1.93(1.74,2.13) and 2.21(1.94,2.51), respectively. There was additive interaction between FPG level and cumulative metabolic parameters with T2D. Compared with participants with the lowest quartile of FPG and low cumulative of all 5 parameters, those with the highest quartile of FPG and high cumulative of 4–5 parameters had a 14.63 [95% CI (12.27, 17.42)] higher risk of incident T2D. Conclusions: Participants with more numbers of high-cumulative metabolic parameters were associated with a higher risk of incident T2D and prediabetes progression. A high level of normal FPG could enhance these risks. [ABSTRACT FROM AUTHOR]

Background: The relationship between sedentary time, physical activity, and chronic back pain remains unclear. The study aims to investigate whether sedentary time and physical activity predict chronic back pain and morphological brain changes. Methods: This cohort study recruited adults aged 37–73 years enrolled between 2006 and 2010, with follow-up until 2014. The total cohort comprised 33,402 participants (mean age: 54.53). Data were collected on daily sedentary time, physical activity, lifestyle factors, and health outcomes. Results: After nearly 8-year follow-up, 3,006 individuals (9.00%) reported chronic back pain in total. Individuals with daily sedentary time exceeding 6 h had a 33% higher risk of chronic back pain compared to those with sedentary time of 2 h or less (RR, 1.33, 95%CI, 1.17–1.52). Sedentary time was also associated with decreased grey matter volume in several brain regions, including bilateral primary somatosensory cortex (S1), secondary somatosensory cortex, putamen, primary motor cortex (M1), insula, hippocampus, amygdala, as well as right supplementary motor area, left medial frontal cortex, and right anterior cingulate cortex (FDR-corrected p-value < 0.05). Compared to individuals who sat for more than 6 h with light physical activity, those engaging in moderate physical activity with sedentary time of 2 h or less (RR, 0.71, 95%CI, 0.52–0.99) exhibited a significant decrease in chronic back pain risk. In addition, replacing sedentary time with equivalent amount of physical activity also demonstrated a reduction in the risk of chronic back pain (RR, 0.87, 95%CI, 0.77–0.99) and increased the reginal grey matter volumes including the amygdala, insula, M1, putamen and S1. Conclusions: Prolonged sedentary time is associated with heightened risks of chronic back pain and deterioration in brain health. [ABSTRACT FROM AUTHOR]

Background: Real-world evidence (RWE) plays a key role in regulatory and healthcare decision-making, but the potentially fragmentated nature of generated evidence may limit its utility for clinical decision-making. Heterogeneity and a lack of reproducibility in RWE resulting from inconsistent application of methodologies across data sources should be minimized through harmonization. Methods: This paper's aim is to describe and reflect upon a multidisciplinary research platform (FOUNTAIN; FinerenOne mUlti-database NeTwork for evidence generAtIoN) with coordinated studies using diverse RWE generation approaches and explore the platform's strengths and limitations. With guidance from an executive advisory committee of multidisciplinary experts and patient representatives, the goal of the FOUNTAIN platform is to harmonize RWE generation across a portfolio of research projects, including research partner collaborations and a common data model (CDM)–based program. FOUNTAIN's overarching objectives as a research platform are to establish long-term collaborations among pharmacoepidemiology research partners and experts and to integrate diverse approaches for RWE generation, including global protocol execution by research partners in local data sources and common protocol execution in multiple data sources through federated data networks, while ensuring harmonization of medical definitions, methodology, and reproducible artifacts across all studies. Specifically, the aim of the multiple studies run within the frame of FOUNTAIN is to provide insight into the real-world utilization, effectiveness, and safety of finerenone across its life-cycle. Results: Currently, the FOUNTAIN platform includes 9 research partner collaborations and 8 CDM-mapped data sources from 7 countries (United States, United Kingdom, China, Japan, The Netherlands, Spain, and Denmark). These databases and research partners were selected after a feasibility fit-for-purpose evaluation. Six multicountry, multidatabase, cohort studies are ongoing to describe patient populations, current standard of care, comorbidity profiles, healthcare resource use, and treatment effectiveness and safety in different patient populations with chronic kidney disease and type 2 diabetes. Strengths and potential limitations of FOUNTAIN are described in the context of valid RWE generation. Conclusion: The establishment of the FOUNTAIN platform has allowed harmonized execution of multiple studies, promoting consistency both within individual studies that employ multiple data sources and across all studies run within the platform's framework. FOUNTAIN presents a proposal to efficiently improve the consistency and generalizability of RWE on finerenone. [ABSTRACT FROM AUTHOR]

Background: Little is known regarding the association between clonal hematopoiesis of indeterminate potential (CHIP) and risk of neurodegenerative diseases. Objective: To estimate the risk of neurodegenerative diseases among individuals with CHIP. Methods: We conducted a community‐based cohort study based on UK Biobank and used Cox regression to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for the risk of any neurodegenerative disease, subtypes of neurodegenerative diseases (including primary neurodegenerative diseases, vascular neurodegenerative diseases, and other neurodegenerative diseases), and specific diagnoses of neurodegenerative diseases (i.e., amyotrophic lateral sclerosis [ALS], Alzheimer's disease [AD], and Parkinson's disease [PD]) associated with CHIP. Results: We identified 14,440 individuals with CHIP and 450,907 individuals without CHIP. Individuals with CHIP had an increased risk of any neurodegenerative disease (HR 1.10, 95% CI: 1.01–1.19). We also observed a statistically significantly increased risk for vascular neurodegenerative diseases (HR 1.31, 95% CI 1.05–1.63) and ALS (HR 1.50, 95% CI 1.05–2.15). An increased risk was also noted for other neurodegenerative diseases (HR 1.13, 95% CI 0.97–1.32), although not statistically significant. Null association was noted for primary neurodegenerative diseases (HR 1.06, 95% CI 0.96–1.17), AD (HR 1.04, 95% CI 0.88–1.23), and PD (HR 1.02, 95% CI 0.86–1.21). The risk increase in any neurodegenerative disease was mainly observed for DNMT3A‐mutant CHIP, ASXL1‐mutant CHIP, or SRSF2‐mutant CHIP. Conclusion: Individuals with CHIP were at an increased risk of neurodegenerative diseases, primarily vascular neurodegenerative diseases and ALS, but potentially also other neurodegenerative diseases. These findings suggest potential shared mechanisms between CHIP and neurodegenerative diseases. [ABSTRACT FROM AUTHOR]

Introduction: Primary Sjögren's syndrome (pSS) is a chronic autoimmune disorder affecting salivary and lacrimal glands, while endometriosis involves uterine‐like tissue growth outside the uterus, causing pelvic pain and infertility. Investigating their intricate relationship using real‐world data is crucial due to limited research on their connection. Material and Methods: This population‐based cohort study included patients with endometriosis and controls without endometriosis. Propensity score matching was used to balance baseline differences in demographic and clinic characteristics between the two groups. Cox proportional hazards model were used to estimate the effect of endometriosis on the risk of new‐onset pSS over time. A symmetrical cohort study, including patients with pSS and propensity score‐matched controls without pSS, was conducted to investigate the effect of pSS on the risk of endometriosis over time. To elaborate on the mechanisms linking endometriosis and pSS, Ingenuity Pathway Analysis was performed to identify activated pathways in eutopic endometrium from patients with endometriosis and parotid tissues from patients with pSS. Results: A total of 15 947 patients with endometriosis and 15 947 propensity score‐matched controls without endometriosis were included. Patients with endometriosis presented a significantly greater risk of pSS compared to non‐endometriosis controls (adjusted hazard ratio, aHR = 1.57, 95% CI = 1.29–1.91, p < 0.001). In the symmetrical cohort study, which included 4906 pSS patients and 4,906 propensity score‐matched controls without pSS, patients with pSS were found to be at a significantly higher risk of endometriosis compared to non‐pSS controls (aHR = 1.51, 95% CI = 1.12–2.04, p = 0.012). Ingenuity Pathway Analysis showed that the underlying cellular mechanisms involved autoimmune‐related pathways, including activation of dendritic cell maturation, and chronic inflammatory pathways, including the fibrosis signaling pathway. Conclusions: These findings support a bidirectional association between endometriosis and pSS, which may be driven by dendritic cell maturation and fibrosis signaling pathways.

Introduction: Hysterectomy has been suggested to increase the risk of urinary incontinence (UI), although evidence is controversial. In our population‐based cohort study, we aimed to assess the independent effect of hysterectomy on the risk of de novo UI. Material and Methods: This is a population‐based cohort study on the women of the Northern Finland Birth Cohort 1966 (n = 5889). We identified all hysterectomies among the cohort (n = 461) using the national Care Register for Health Care and classified them according to surgical approach into laparoscopic (n = 247), vaginal (n = 107), and abdominal hysterectomies (n = 107). Women without hysterectomy formed the reference group (n = 3495). All women with UI diagnoses and operations were identified in the register, and women with preoperative UI diagnosis (n = 36) were excluded from the analysis to assess de novo UI. Data on potential confounding factors were collected from registers and the cohort questionnaire. Incidences of different UI subtypes and UI operations were compared between the hysterectomy and the reference groups, and further disaggregated by different hysterectomy approaches. Logistic regression models were used to analyze the association between hysterectomy and UI, with adjustments for several UI‐related covariates. Results: We found no significant difference in the incidence of UI diagnoses or the rate of subsequent UI operations between the hysterectomy and the reference groups (24 [5.6%] vs. 166 [4.7%], p = 0.416 and 14 [3.3%] vs. 87 [2.5%], p = 0.323). Hysterectomy was not significantly associated with the risk of any subtype of UI (overall UI: OR 1.20, 95% CI 0.77–1.86; stress UI (SUI): OR 1.51, 95% CI 0.89–2.55; other UI: OR 0.80, 95% CI 0.36–1.74). After adjusting for preoperative pelvic organ prolapse (POP) diagnoses, the risk was decreased (overall UI: OR 0.54, 95% CI 0.32–0.90; other than SUI: OR 0.40, 95% CI 0.17–0.95). Regarding different hysterectomy approaches, the risks of overall UI and SUI were significantly increased in vaginal, but not in laparoscopic or abdominal hysterectomy. However, adjusting for preoperative POP diagnosis abolished these risks. Conclusions: Hysterectomy is not an independent risk factor for de novo UI. Instead, underlying POP appears to be a significant risk factor for the incidence of UI after hysterectomy. [ABSTRACT FROM AUTHOR]

Objective: The 'two-hit' hypothesis theorizes that early life allergic sensitization and respiratory infection interact to increase asthma risk. Methods: We sought to determine in a high allergy risk birth cohort whether interactions between early life allergic sensitization and respiratory infection were associated with increased risk for asthma at ages 6–7 years and 18 years. Allergic sensitization was assessed at 6, 12, and 24 months by skin prick testing to 3 food and 3 aeroallergens. Respiratory infection was defined as reported "cough, rattle, or wheeze" and assessed 4-weekly for 15 months, at 18 months, and age 2 years. Regression analysis was undertaken with parent-reported asthma at age 6–7 years and doctor diagnosed asthma at 18 years as distinct outcomes. Interactions between allergic sensitization and respiratory infection were explored with adjustment made for potential confounders. Results: Odds of asthma were higher in sensitized compared to nonsensitized children at age 6–7 years (OR = 14.46; 95% CI 3.99–52.4), There was no evidence for interactions between allergic sensitization and early life respiratory infection, with a greater frequency of respiratory infection up to 2 years of age associated with increased odds for asthma at age 6–7 years in both sensitized (OR = 1.13; 95% CI 1.02–1.25, n = 199) and nonsensitized children (OR = 1.31; 1.11–1.53, n = 211) (p interaction = 0.089). At age 18 years, these associations were weaker. Conclusions: Our findings do not support 'two-hit' interactions between early life allergic sensitization and respiratory infection on asthma risk. Both early life respiratory infections and allergic sensitization were risk factors and children with either should be monitored closely for development of asthma. [ABSTRACT FROM AUTHOR]
