The promise of community-driven preprints in ecology and evolution.

Proc Biol Sci

January 2025

Evolution and Ecology Research Centre, School of Biological, Earth and Environmental Sciences, University of New South Wales, Sydney, New South Wales 2052, Australia.

Publishing preprints is quickly becoming commonplace in ecology and evolutionary biology. Preprints can facilitate the rapid sharing of scientific knowledge establishing precedence and enabling feedback from the research community before peer review. Yet, significant barriers to preprint use exist, including language barriers, a lack of understanding about the benefits of preprints and a lack of diversity in the types of research outputs accepted (e.

Background: Long-lasting insecticidal nets (LLINs) were once fully effective for the prevention of malaria; however, mosquitoes have developed resistance to pyrethroids, the main class of insecticides used on nets. Dual active ingredient LLINs (dual-AI LLINs) have been rolled out as an alternative to pyrethroid (PY)-only LLINs to counteract this. Understanding the minimum community usage at which these LLINs elicit an effect that also benefits non-users against malaria infection is important.

Background: Hematopoietic stem cell transplantation (HSCT) is a common therapy for many hematologic malignancies. While advances in transplant practice have improved cancer-specific outcomes, multiple and debilitating long term physical and psychologic effects remain. Patients undergoing allogeneic bone marrow transplantation (allo-BMT) are often critically ill at initial diagnosis and with necessary sequential treatments become increasingly frail and deconditioned.

An exploratory survey assessing the determinants of heat stress and heat strain in the Canadian mining industry from the worker's perspective.

J Occup Environ Hyg

January 2025

Human and Environmental Physiology Research Unit, School of Human Kinetics, Faculty of Health Sciences, University of Ottawa, Ottawa, Ontario, Canada.

With mines extending deeper and rising surface temperatures, workers are exposed to hotter environments. This study aimed to characterize heat stress and strain in the Canadian mining industry and evaluate the utility of the Heat Strain Score Index (HSSI), combined with additional self-reported adverse health outcomes. An exploratory web-based survey was conducted among workers ( = 119) in the Canadian mining industry.

Mixed results have been reported regarding the link between different types of maternal diabetes and attention deficit hyperactivity disorder (ADHD) in offspring. Hence, we conducted a systematic review and meta-analysis to explore these associations. Relevant studies on the subject were retrieved from six major databases, including PubMed, Medline, Embase, Scopus, CINAHL, and PsychINFO.

This study investigated the sexual dimorphism in right ventricle (RV) remodeling in right heart failure susceptible Fischer CDF rats using the pulmonary artery banding (PAB) model. Echocardiography and hemodynamic measurements were performed in adult male and female Fischer CDF rats at 1- or 2-weeks post-PAB. RV systolic pressure and RV hypertrophy were significantly elevated in PAB rats compared to sham control at 1- and 2-weeks post-PAB; however, no differences were observed between male and female rats.

Metabolic disease is rising along with both global industrialization and the use of new commercial, agricultural, and industrial chemicals and food additives. Exposure to these compounds may contribute to aspects of metabolic disease such as obesity, diabetes, and fatty liver disease. Ingesting compounds in the food supply is a key route of human exposure, resulting in the interaction between toxicants or additives and the intestinal microbiota.

Background: There are limited studies of juvenile dermatomyositis (JDM) in low and middle-income countries (LMIC). Many demonstrate delays to care, high prevalence of severe manifestations, and high mortality. Given the disease-associated damage with JDM, understanding JDM in Africa further is critical.

Background: Non-communicable diseases in adulthood are reported to be strongly associated with adolescent obesity. The present study aimed to assess the effect of a comprehensive lifestyle modification intervention on the anthropometric indices, dietary intake, and physical activity of adolescent boys with overweight.

Methods: This pragmatic trial was conducted on 126 adolescent boys with overweight.

Axons in the mammalian brain show significant diversity in myelination motifs, displaying spatial heterogeneity in sheathing along individual axons and across brain regions. However, its impact on neural signaling and susceptibility to injury remains poorly understood. To address this, we leveraged cable theory and developed model axons replicating the myelin sheath distributions observed experimentally in different regions of the mouse central nervous system.

We evaluated enterocyte damage (IFABP), microbial translocation (sCD14), and inflammatory responses (TNF-α, IL-6, CRP) in 16 older adults (66-78 years) during 8 hours rest in conditions simulating homes maintained at 22°C (control), the 26°C indoor temperature upper limit proposed by health agencies, and homes without air-conditioning during heatwaves (31°C, 36°C). Relative to 22°C, IFABP was elevated ~181 pg/mL after exposure to 31°C (P=0.07), and by ~378 pg/mL (P<0.

Optimizing the long-term care and follow-up of living kidney donors (LKDs) has been challenging, and prior LKDs have reported suboptimal healthcare experiences. Long-term care of LKDs is largely undertaken by primary care practitioners such as family physicians (FPs). We conducted a cross-sectional survey of Canadian FPs (n = 151).

Purpose: Involving patients in developing patient-reported outcome measures (PROMs) is essential for accurately capturing their perspectives. However, understanding how patients were involved in developing PROMs used after hip or knee arthroplasty is limited. This scoping review aimed to evaluate whether patients were involved in the development of these PROMs and how they were involved.

Steatotic liver disease is prevalent among people with hepatitis C virus (HCV). The new definition of metabolic dysfunction-associated steatotic liver disease (MASLD) emphasises the metabolic drivers of steatosis and recognises its frequent coexistence with other chronic liver diseases, including HCV. We aimed to evaluate the association of coexisting MASLD and HCV with liver fibrosis.

Rationale: Osteoporosis is an abnormal reduction in bone mass and bone deterioration, leading to increased fracture risk. Alendronate belongs to the bisphosphonate class of drugs, which inhibit bone resorption by interfering with the activity of osteoclasts (bone cells that break down bone tissue). This is an update of a Cochrane review first published in 2008.

Introduction: Patients with relapsed/refractory diffuse large B-cell lymphoma (R/R DLBCL) have an unmet medical need. The objective of this trial was to assess the efficacy and toxicities of a novel triple immunotherapy regimen-pembrolizumab, low-dose cyclophosphamide, and maveropepimut-S (MVP-S). This regimen was designed to activate tumor-specific T cells by targeting the tumor-associated antigen survivin with MVP-S and reducing two important T cell inhibitory pathways: T cell exhaustion and regulatory T cells with pembrolizumab and metronomic cyclophosphamide, respectively.
