ABSTRACT

BACKGROUND: Maintaining physical activity throughout life is crucial for overall health and wellbeing. Yet the age-related decline in average physical activity, a natural phenomenon also observed in animals, poses a challenge. This study aimed to investigate whether participation in organised sports supported by the Swiss Youth+Sports (Y+S) programme is associated with sustaining or enhancing physical activity among children and adolescents during 5 years of follow-up.

METHODS: The longitudinal study was nested in the population-based SOPHYA (Swiss children’s Objectively measured PHYsical Activity) cohort. Participants aged 6-16 years at SOPHYA1 (2014) with complete accelerometer data from baseline and follow-up assessment (SOPHYA2, 2019) were included. The primary exposure was participation in organised sport during the follow-up period, calculated by linkage with the Y+S database as the number of days with at least one activity in Y+S-offered programmes for ages 5 to 20 years. The primary outcome was the categorisation of participants into physical activity “improvers” or “worseners”. Improvers in the respective physical activity categories – total activity counts per minute (CPM), minutes in moderate-to-vigorous activity (MVPA), minutes in light activity (LPA) and minutes in sedentary behaviour (SB) – increased or maintained their active physical activity during the 5 follow-up years. Information on confounders and effect modifiers (sex, age, body mass index (BMI), language region, household income, education) was obtained by self-report at baseline. Logistic regressions examined the relationship between organised sport participation and the probability of being a physical activity improver in each physical activity intensity category separately. Covariates for the final models were selected through a stepwise procedure based on the Bayesian information criterion from a maximal model containing all covariates as well as all two-way interactions with organised sport and between them. All models were a priori adjusted for technical variables (season of measurement; wear time; duration of follow-up).

RESULTS: The analysis included 432 participants. There was a strong CPM, MVPA and LPA decline from 2014 to 2019, but an increase in SB. Nevertheless, the prevalence of improvers was 22.5% for CPM, 9.5% for MVPA, 26.9% for LPA and 9.7% for SB. Engagement in organised sport between 2014 and 2019 was positively associated with CPM, MVPA and SB, but not with LPA improver status. For 30 additional days of participation in organised sport over the five years of the study, the odds of being an improver vs being a worsener increased by 4.0% for CPM (95% CI: 0.13-7.69), 6.2% for MVPA (95% CI: 0.82-11.54) and 6.0% for SB (95% CI:-1.49-13.97).

CONCLUSION: The results provide supporting evidence that organised sport in the context of the Swiss Y+S programme may empower the young to maintain an active lifestyle and even offset the age-related decline in physical activity.

ABSTRACT

BACKGROUND: Routine process and outcome monitoring interventions added to psychotherapy are known to improve treatment outcomes, although they vary in format and effectiveness.

OBJECTIVE: This study aimed to evaluate whether a therapist-independent, internet-based routine process monitoring and feedback system could significantly reduce psychological distress and enhance the quality of the therapeutic relationship compared with a treatment-as-usual control group among individuals already engaged in individual psychotherapy.

METHODS: We randomized 475 participants into either the intervention group, which received access to an internet-based routine process monitoring and feedback system in addition to psychotherapy, or the control group, which received only psychotherapy. The trial lasted for 10 weeks. Follow-up assessments at 5 weeks and 10 weeks used the Clinical Outcomes in Routine Evaluation-Outcome Measure as the primary outcome, with the Working Alliance Inventory-Short Revised and the Real Relationship Inventory-Client form as secondary outcomes.

RESULTS: Per-protocol analyses (n=166) showed that psychological distress decreased in both groups, but there was no significant advantage for the intervention group. The intervention group experienced a decline in the genuineness dimension score of the real relationship, with an effect size of d=-0.27, compared with d=0.01 in the control group. In the intervention group (but not in the control group), dropouts showed significantly lower real relationship levels (P=.002), working alliance quality (P=.051), and emotional disclosure (P=.01) compared with those who completed the study. Additionally, logistic regression revealed distinct predictors of dropout within the control group and intervention group.

CONCLUSIONS: The findings do not provide conclusive evidence for the efficacy of the new internet-based intervention in enhancing self-monitoring and prompting reflection on patients’ emotional responses to their therapists. However, the intervention appears to influence patients’ perceptions of the genuineness dimension in the therapeutic relationship, warranting further investigation. We hypothesize that this alteration in the genuineness dimension could be attributed to the intervention facilitating a more realistic and accurate perception of the therapeutic relationship among participants.

ABSTRACT

Background: The relationship between different types of autoimmune diseases and myelodysplastic syndrome (MDS) is inconclusive. Therefore, we employed Mendelian randomization (MR) to examine whether genetically predicted susceptibility to ten autoimmune diseases is associated with the risk of MDS.Methods: Single nucleotide polymorphisms (SNPs) significantly associated with 10 autoimmune diseases were extracted from the summary statistics of European genome-wide association studies (GWAS). A two-sample MR analysis was performed using summary-level statistics sourced from GWAS datasets. Inverse-variance weighting (IVW), MR-Egger, and weighted median (WM) were further supported by several sensitivity analyses.Results: Four autoimmune diseases showed genetical predisposition to MDS: rheumatoid arthritis (OR = 1.186,95% CI = 1.028-1.367, P = 0.019), multiple sclerosis (OR = 1.247, 95% CI = 1.013-1.534, P = 0.037), myasthenia gravis (OR = 1.326,95% CI = 1.010-1.742, P = 0.042), and Hashimoto thyroiditis(OR = 1.519,95% CI = 1.008-2.290, P = 0.046). Nevertheless, no similar causal relationship was found between the remaining seven autoimmune diseases and MDS. The accuracy and robustness of these findings were confirmed by sensitivity tests.Conclusions: We are the first to use MR analysis to explore the relationship between autoimmune diseases and MDS. The mechanism needs to be further explored.

ABSTRACT

Objective: The current study explored the relationships of religiosity and coping behaviors on the perceived mental health of undergraduate African American (AA) college students enrolled at a large public university in the Southern United States. Methods: We used a cross-sectional survey design. AA and/or African descent adult college participants (n = 131) were recruited from an online chat group (ie, GroupMe) and completed the Brief-COPE, a demographic questionnaire, and a single-item mental health tool. Data analyses employing descriptive statistics and correlational analyses examined relationships between variables. Results: There was a positive correlation between increased religious activity and overall mental health. Those who specified their religion as “other” had a lower total mental health score than those with an identified religion. Conclusions: Findings underscore the importance of supportive interventions that account for religious beliefs and activities on overall mental health outcomes for undergraduate AA college students in the South.

ABSTRACT

Breast cancer can lead to changes in appearance and subsequent concerns about body image. This study aimed to translate the body investment instrument, Appearance Schemas Inventory-Revised (ASI-R), to Swedish, and perform a validation in women who underwent mastectomy and were awaiting breast reconstruction. The instrument was translated, and its psychometric properties were investigated according to current guidelines. Three hundred and ninety-seven women were eligible for the study, and 215 (54%) participants responded. An exploratory factor analysis (EFA) revealed that a three-factor structure was the most adequate solution. Three new subscales were suggested: body image investment cognition; breast and body image investment emotions; breast reflecting dysfunctional cognitive and emotional patterns of appearance investment and body image investment behaviors; breast reflecting positive ways of investing in body image. Consistent with previous findings, control over appearance is a central theme in women with breast cancer undergoing mastectomy and reconstruction. The obtained factor structure was considered similar to the original structure and three-factor solutions obtained from an American cohort of patients with breast cancer. The ASI-R has shown good psychometric properties in Swedish women undergoing mastectomy and reconstruction. Further studies on convergent validity and confirmatory factor analysis are required.

ABSTRACT

IMPORTANCE: Evidence suggests that prophylactic abdominal drainage after gastrectomy for cancer may reduce postoperative morbidity and hospital stay but this evidence comes from small studies with a high risk of bias. Further research is needed to determine whether drains safely meet their primary purpose of identifying and managing postoperative intraperitoneal collections without the need for reoperation or additional percutaneous drainage.

OBJECTIVE: To determine whether avoiding routine abdominal drainage increased postoperative invasive procedures.

DESIGN, SETTING, AND PARTICIPANTS: The Abdominal Drain in Gastrectomy (ADIGE) Trial was a multicenter prospective randomized noninferiority trial. Enrollment spanned from December 2019 to January 2023. Follow-up evaluations were completed at 30 and 90 days. Eleven centers within the Italian Research Group for Gastric Cancer, encompassing both academic medical centers and community hospitals, were included. Patients with gastric cancer undergoing subtotal or total gastrectomy with curative intent were eligible, excluding those younger than 18 years, with serious comorbidities, or undergoing procedure types outside the scope of the study. Of 803 patients assessed for eligibility, 404 were randomized and 390 were included in final analyses.

INTERVENTIONS: Patients were randomized 1:1 into prophylactic drain or no drain arms.

MAIN OUTCOMES AND MEASURES: The primary end point was a modified intention-to-treat (mITT) analysis measuring reoperation or percutaneous drainage within 30 postoperative days. The null hypothesis was rejected when the 90% CI upper limit of the proportion difference did not exceed 3.56%. The calculated sample size to achieve 80% power with a 10% dropout rate was 404 patients (202 in each group). Surgeons and patients were blinded until gastrointestinal reconstruction.

RESULTS: Of the 404 patients randomized 226 (57.8%) were male; the median (IQR) age was 71 (62-78) years. Intraoperative identification of nonresectable disease occurred in 14 patients, leading to their exclusion from the study, leaving 390 patients. In the mITT analysis, 15 patients (7.7%) in the drain group needed reoperation or percutaneous drainage by postoperative day 30 vs 29 (15%) in the no drain group, favoring the drain group (difference, 7.2%; 90% CI, 2.1-12.4; P = .02). Of note, the difference in the primary composite end point was entirely due to a similar difference in reoperation (5.1% in the drain group vs 12.4% in the no drain group; P = .01). Drain-related complications occurred in 4 patients.

CONCLUSIONS AND RELEVANCE: The findings of this study indicate that refraining from prophylactic drain use after gastrectomy heightened the risk of postoperative invasive procedures, discouraging its avoidance. Future studies identifying high-risk groups could optimize prophylactic drainage decisions.

ABSTRACT

IMPORTANCE: Prurigo nodularis (PN) is a chronic and debilitating skin condition, characterized by intense itch with multiple nodular lesions. Nemolizumab demonstrated significant improvements in itch and skin nodules in adults with moderate to severe PN in a previous 16-week phase 3 study (OLYMPIA 2).

OBJECTIVE: To assess the efficacy and occurrence of adverse events in adults with moderate to severe PN treated with nemolizumab vs those receiving placebo.

DESIGN, SETTING, AND PARTICIPANTS: OLYMPIA 1 was a multicenter, placebo-controlled, phase 3 randomized clinical trial, conducted from August 2020 to March 2023 at 77 centers across 10 countries in adults with moderate to severe PN (at least 20 nodules and an Investigator’s Global Assessment [IGA] score ≥3) and Peak Pruritus Numerical Rating Scale (PP-NRS) score of at least 7.0; consisted of screening (up to 4 weeks), 24-week treatment, and 8-week follow-up periods.

INTERVENTIONS: Patients were randomized (2:1) to nemolizumab monotherapy, 30 mg or 60 mg (depending on baseline weight of less than 90 kg vs 90 kg or greater, respectively), or matching placebo administered every 4 weeks for 24 weeks.

MAIN OUTCOMES AND MEASURES: The primary end points were the proportion of patients with itch response (≥4-point improvement from baseline in weekly average PP-NRS) and IGA success (score of 0/1 [clear/almost clear] and 2-grade or more improvement from baseline) at week 16.

RESULTS: Of 286 patients (mean [SD] age, 57.5 [13.0] years; mean [SD] body weight, 85.0 [20.7] kg; 166 [58.0%] female), 190 were randomized to receive nemolizumab, and 96 were randomized to placebo. A significantly greater proportion of patients assigned to nemolizumab vs placebo achieved itch response (111/190 [58.4%] vs 16/96 [16.7%]; Δ, 40.1% [95% CI, 29.4%-50.8%]; P < .001) and IGA success (50/190 [26.3%] vs 7/96 [7.3%]; Δ, 14.6% [95% CI, 6.7%-22.6%]; P = .003) at week 16. At week 24, the proportion of patients with itch response was 58.3% vs 20.4% (Δ, 38.7% [95% CI, 27.5%-49.9%]) in the ad hoc analysis, and IGA success was 58/190 (30.5%) vs 9/96 (9.4%) (Δ, 19.2% [95% CI, 10.3%-28.1%]) in the nemolizumab-treated vs placebo group. During the treatment period, 134 patients (71.7%) receiving nemolizumab vs 62 patients (65.3%) receiving placebo had at least 1 adverse event; most events were of mild to moderate severity.

CONCLUSIONS AND RELEVANCE: In this randomized clinical trial, nemolizumab monotherapy led to clinically meaningful and statistically significant improvements in core signs and symptoms of PN.

ABSTRACT

Cannabis sativa L., known for its medicinal and psychoactive properties, has recently experienced rapid market expansion but remains understudied in terms of its fundamental biology due to historical prohibitions. This pioneering study implements GS and ML to optimize cannabinoid profiles in cannabis breeding. We analyzed a representative population of drug-type cannabis accessions, quantifying major cannabinoids and utilizing high-density genotyping with 250K SNPs for GS. Our evaluations of various models-including ML algorithms, statistical methods, and Bayesian approaches-highlighted Random Forest’s superior predictive accuracy for single and multi-trait genomic predictions, particularly for THC, CBD, and their precursors. Multi-trait analyses elucidated complex genetic interdependencies and identified key loci crucial to cannabinoid biosynthesis. These results demonstrate the efficacy of integrating GS and ML in developing cannabis varieties with tailored cannabinoid profiles.
