Requirements for occupational exposure limits in psychosocial risk assessment: What we know, what we don't know and what we can learn from other disciplines.

Objectives: This discussion paper aims to provide recommendations for the development of occupational exposure limits (OEL) for psychosocial hazards. By comparing the characteristics of non-psychosocial and psychosocial hazards at work as well as approaches to derive occupational limit values for both types of hazards, the paper summarizes conceptual requirements and methodological perspectives for OEL in psychosocial risk assessment.

Methods: An interdisciplinary working group comprised of academics, active practitioners in company occupational health management and members of national committees advising policymakers conducted regular face-to-face and online meetings between October 2022 and August 2024 to draft a narrative review and discussion of the current state of research on OEL for psychosocial hazards within the fields of psychology, sociology and medicine.

Polo-like kinase 1 maintains transcription and chromosomal accessibility during mitosis.

Transcription persists at low levels in mitotic cells and plays essential roles in mitotic fidelity and chromosomal dynamics. However, the detailed regulatory network of mitotic transcription remains largely unresolved. Here, we report the novel role of Polo-like kinase 1 (Plk1) in maintaining mitotic transcription.

Cell-intrinsic platinum response and associated genetic and gene expression signatures in ovarian cancer.

Ovarian cancers are still largely treated with platinum-based chemotherapy as the standard of care, yet few biomarkers of clinical response have had an impact on clinical decision making. Previous work has relied on poor models of the most common subtypes of epithelial ovarian cancers and necessitates a careful examination of the most suitable in vitro models. We performed extensive drug dose response assays and gene expression profiling on 36 ovarian cancer cell lines across over seven subtypes.

MYC Regulates a DNA Repair Gene Expression Program in Small Cell Carcinoma of the Ovary, Hypercalcemic Type.

Background/objectives: SCCOHT is an aggressive and often fatal cancer that belongs to the ~20% of cancers defined by mutations to subunits of the SWI/SNF chromatin remodeling complex. In SCCOHT, mutations to the gene, which encodes the SWI/SNF ATPase BRG1, are sufficient to impair SWI/SNF function. This single genetic lesion leads to a cascade of events that promote tumorigenesis, some of which may involve the intersection of SWI/SNF with oncogenic pathways such as those regulated by the oncogene.

Loss of SMARCA4 Leads to Intron Retention and Generation of Tumor-Associated Antigens in Small Cell Carcinoma of the Ovary, Hypercalcemic Type.

Unlabelled: Small cell carcinoma of the ovary, hypercalcemic type (SCCOHT), is a rare, deadly form of ovarian cancer that uniformly harbors mutations in SMARCA4, a member of the SWI/SNF chromatin remodeling complex. SWI/SNF impacts RNA splicing, and dysregulation of splicing can generate immunogenic tumor antigens. In this study, we explored the relationship between SMARCA4 loss and RNA splicing dysregulation.

The Role of Optimism and Self-Efficacy in the Relationship between Academic Stress and Depressive Symptoms in Medical Students Including the Use and Knowledge of Structural Health Promotion Offers.

Background: In recent years, studies have highlighted that stress levels among medical students are alarmingly high. The study aim was to examine how academic stress and depressive symptoms in medical students are affected by individual moderators (self-efficacy/optimism) and structural influencing factors (health promotion offers).

Methods: Data collection occurred at three measurement points during the first 1.

Polo-like kinase 1 maintains transcription and chromosomal accessibility during mitosis.

Unlabelled: Transcription persists at low levels in mitotic cells and plays essential roles in mitotic fidelity and chromosomal dynamics. However, the detailed regulatory network of mitotic transcription remains largely unresolved. Here, we report the novel role of Polo-like kinase 1 (Plk1) in maintaining mitotic transcription.

Super-enhancers and efficacy of triptolide in small cell carcinoma of the ovary hypercalcemic type.

Small cell carcinoma of the ovary-hypercalcemic type (SCCOHT) is a rare ovarian cancer affecting young females and is driven by the loss of both SWI/SNF ATPases SMARCA4 and SMARCA2. As loss of SWI/SNF alters enhancers, we hypothesized that super-enhancers, which regulate oncogene expression in cancer, are disparately impacted by SWI/SNF loss. We discovered differences between SWI/SNF occupancy at enhancers vs.

Higher fiber higher carbohydrate diets better than lower carbohydrate lower fiber diets for diabetes management: Rapid review with meta-analyses.

Background: Some dietary recommendations continue to recommend carbohydrate restriction as a cornerstone of dietary advice for people with diabetes.

Purpose: We compared the cardiometabolic effects of diets higher in both fiber and carbohydrate with lower carbohydrate lower fiber diets in type 1 or type 2 diabetes.

Data Sources: MEDLINE, Embase, and the Cochrane Database of Systematic Reviews up to June 24, 2024, with additional hand searching.

Cell-intrinsic platinum response and associated genetic and gene expression signatures in ovarian cancer cell lines and isogenic models.

Ovarian cancers are still largely treated with platinum-based chemotherapy as the standard of care, yet few biomarkers of clinical response have had an impact on clinical decision making as of yet. Two particular challenges faced in mechanistically deciphering platinum responsiveness in ovarian cancer have been the suitability of cell line models for ovarian cancer subtypes and the availability of information on comparatively how sensitive ovarian cancer cell lines are to platinum. We performed one of the most comprehensive profiles to date on 36 ovarian cancer cell lines across over seven subtypes and integrated drug response and multiomic data to improve on our understanding of the best cell line models for platinum responsiveness in ovarian cancer.

Conflicting patterns of cardiovascular reactivity, self-report, and behavior associated with social anxiety during a conversation with a close friend.

Social anxiety (SA) is characterized by anxious symptomology and fear during social situations, but recent work suggests that SA may not necessarily be associated with negative interpersonal and intrapersonal outcomes in support contexts. The current research investigates the discrepancies between self-perceptions, behavior, and physiological responses associated with SA in social support conversations with close friends. Specifically, we examined the associations between SA and positive and negative affect, perceptions of demands and resources, and responsiveness.

TP53 mutations and the association with platinum resistance in high grade serous ovarian carcinoma.

Objectives: Alterations in the tumor suppressor TP53 gene are the most common mutations in high grade serous ovarian carcinoma. The impact of TP53 mutations on clinical outcomes and platinum resistance is controversial. We sought to evaluate the genomic profile of high grade serous ovarian carcinoma and explore the association of TP53 mutations with platinum resistance.

Occupational exposure to polychlorinated biphenyls: Development of neuropsychological functions over time.

Occupational exposure to polychlorinated biphenyls (PCBs) continues to affect the health of exposed individuals until today. This study aims to expand previous findings by examining the development of neuropsychological functions of occupationally exposed participants over time. Especially verbal fluency and sensorimotor processing, found to be impaired in a previous study, were thus of particular interest.

CD8+ cells and small viral reservoirs facilitate post-ART control of SIV replication in M3+ Mauritian cynomolgus macaques initiated on ART two weeks post-infection.

Sustainable HIV remission after antiretroviral therapy (ART) withdrawal, or post-treatment control (PTC), remains a top priority for HIV treatment. We observed surprising PTC in an MHC-haplomatched cohort of MHC-M3+ SIVmac239+ Mauritian cynomolgus macaques (MCMs) initiated on ART at two weeks post-infection (wpi). None of the MCMs possessed MHC haplotypes previously associated with SIV control.

Ten years after: findings from the medical surveillance program on Health Effects in High-Level Exposure to PCB (HELPcB).

After the detection of high environmental and occupational exposure to polychlorinated biphenyls (PCBs) in a German recycling company for transformers and capacitors in 2010, the multidisciplinary medical surveillance program "HELPcB" (Health Effects in High-Level Exposure to PCB) was established for former PCB-exposed workers of the company, their family members, employees of surrounding companies, and area residents to investigate potential adverse health effects by PCB exposure in a longitudinal study approach with up to seven examination time points between 2010 and 2019. More than 300 individuals were enrolled into the program. Assessments particularly included plasma and urine concentrations of PCB congeners and their metabolites, clinical laboratory parameters, Comet assay, analysis of telomere length, neuropsychological examinations, psychological screening, abdominal and thyroid ultrasound examination.

Patients' and Caregivers' Preferences for Mental Health Care and Support in Atopic Dermatitis.

Atopic dermatitis (AD) has large mental health impacts for patients and caregivers, yet their preferences regarding how to relieve these impacts are poorly understood. To understand patients' and caregivers' preferences for AD-related mental health care and support. We surveyed 279 adult AD patients and 154 caregivers of children with AD across 26 countries regarding their AD-related mental health burden, preferred strategies for improving AD-related mental health, and experiences with mental health care in AD.

Pilot clinical trial and phenotypic analysis in chemotherapy-pretreated, metastatic triple-negative breast cancer patients treated with oral TAK-228 and TAK-117 (PIKTOR) to increase DNA damage repair deficiency followed by cisplatin and nab paclitaxel.

Background: A subset of triple-negative breast cancers (TNBCs) have homologous recombination deficiency with upregulation of compensatory DNA repair pathways. PIKTOR, a combination of TAK-228 (TORC1/2 inhibitor) and TAK-117 (PI3Kα inhibitor), is hypothesized to increase genomic instability and increase DNA damage repair (DDR) deficiency, leading to increased sensitivity to DNA-damaging chemotherapy and to immune checkpoint blockade inhibitors.

Methods: 10 metastatic TNBC patients received 4 mg TAK-228 and 200 mg TAK-117 (PIKTOR) orally each day for 3 days followed by 4 days off, weekly, until disease progression (PD), followed by intravenous cisplatin 75 mg/m plus nab paclitaxel 220 mg/m every 3 weeks for up to 6 cycles.

Antecedents, outcomes and measurement of work related-cognition in non-work time: A multistudy report using the work-related rumination questionnaire in two languages.

According to the perseverative cognition hypothesis, prolonged activation for example, work-related rumination impairs recovery and thereby poses a risk to employee health. The extent to which gender, age, occupation or longitudinal stress exposure may alter work-related rumination is an ongoing debate. Whether group or longitudinal comparisons of work-related rumination are valid, however, has never been tested.

CD8+ cells and small viral reservoirs facilitate post-ART control of SIV in Mauritian cynomolgus macaques.

Sustainable HIV remission after antiretroviral therapy (ART) withdrawal, or post-treatment control (PTC), remains a top priority for HIV treatment. We observed surprising PTC in an MHC-haplomatched cohort of MHC-M3+ SIVmac239+ Mauritian cynomolgus macaques (MCMs) initiated on ART at two weeks post-infection (wpi). For six months after ART withdrawal, we observed undetectable or transient viremia in seven of eight MCMs.

The relevance of pharmacological neuroenhancement for stress and resilience-A multistudy report.

Background: Pharmacological neuroenhancement (PNE) is discussed as coping strategy in academic and work-related contexts. Depending on the definition of PNE and sample population, different prevalence rates for various groups have been reported. In the three parts of the study, prevalence rates for work and student populations in Germany are detected and the reasons for PNE and possible causal associations between PNE, stress and resilience are investigated.

Patients' and Caregivers' Experiences With Atopic Dermatitis-Related Burden, Medical Care, and Treatments in 8 Countries.

Background: Previous studies have documented the high patient and caregiver burden associated with atopic dermatitis (AD). Less is known about the factors-especially those related to treatment options and the delivery of medical care-that may relate to burden and unmet needs among patients and their caregivers.

Objective: Our primary aim was to characterize and compare health-related quality of life, long-term control of symptoms, satisfaction with treatments, the financial burden, and the prevalence of patient-centered care among adult and pediatric patients with AD in 8 developed nations.

Sustainable return to work after depression - A comparative study among occupational physicians and affected employees.

Introduction: The number of sick days taken from work due to depression is steadily rising. A successful return to work (RTW) is essential for sustainable reintegration. This study aims to identify factors to optimize RTW and to investigate approaches for sustainable RTW (sRTW) after depressive episodes.

Faecalibaculum rodentium remodels retinoic acid signaling to govern eosinophil-dependent intestinal epithelial homeostasis.

The intestinal epithelium plays critical roles in sensing and integrating dietary and microbial signals. How microbiota and intestinal epithelial cell (IEC) interactions regulate host physiology in the proximal small intestine, particularly the duodenum, is unclear. Using single-cell RNA sequencing of duodenal IECs under germ-free (GF) and different conventional microbiota compositions, we show that specific microbiota members alter epithelial homeostasis by increasing epithelial turnover rate, crypt proliferation, and major histocompatibility complex class II (MHCII) expression.

The moderating effect of social resources on the link between study-related stressors and depressive symptoms among medical students in North Rhine-Westphalia, Germany - a cross-sectional study.

Background: Previous research has demonstrated the negative effects of study-related stressors on the mental health of medical students. It has been found that social resources such as social identity, dual identity and social support help buffer negative mental health outcomes. Notably, social status has been found to weaken the connection between stress and depressive symptoms.
