Predicting the replicability of social and behavioural science claims in COVID-19 preprints.

Replications are important for assessing the reliability of published findings. However, they are costly, and it is infeasible to replicate everything. Accurate, fast, lower-cost alternatives such as eliciting predictions could accelerate assessment for rapid policy implementation in a crisis and help guide a more efficient allocation of scarce replication resources.

Evolution of a bipolar sexual compatibility system in .

Sexual compatibility in the Basidiomycota is governed by genetic identity at one or two loci, resulting in compatibility systems called bipolar and tetrapolar. The loci are known as and , encoding homeodomain transcription factors and pheromone precursors and receptors, respectively. Bipolarity is known to evolve either by linkage of the two loci or by loss of mating-type determination of either the or the locus.

Legal obstacles jeopardise research in personalised medicine - experiences from a Nordic collaboration within rheumatology.

Aims: Personalised medicine in chronic complex diseases such as rheumatoid arthritis (RA) is within reach but requires international multi-stakeholder collaboration. We exemplify how national implementations of the General Data Protection Regulation (GDPR) have introduced administrative delays and created disincentives for data sharing and collaborative research.

Methods: Our Danish/Swedish/Norwegian research collaboration (the 3-year NordForsk-funded "NORA" project) aims to develop a personalised medicine approach for the management of RA, built on the exploitation of unique existing data sources: longitudinal data from clinical rheumatology registries, research cohorts, nationwide health care registries, and biobank material from >20 sample collections.

Coupling of twelve putative chromosomal inversions maintains a strong barrier to gene flow between snail ecotypes.

Chromosomal rearrangements can lead to the coupling of reproductive barriers, but whether and how they contribute to the completion of speciation remains unclear. Marine snails of the genus repeatedly form hybrid zones between populations segregating for multiple inversion arrangements, providing opportunities to study their barrier effects. Here, we analyzed 2 adjacent transects across hybrid zones between 2 ecotypes of ("large" and "dwarf") adapted to different wave exposure conditions on a Swedish island.

Self-confidence as a mediator in the relationship between executive functioning and depression among ICU survivors: a latent variable analysis.

Background: Executive dysfunction and depression are common among ICU survivors, yet the mechanisms linking these two factors remain poorly understood. Self-confidence has been implicated as a key mediator in the relationship between cognitive impairments and mental health outcomes. This study aimed to explore the mediating role of self-confidence in the association between executive functioning and depression in ICU survivors.

Airborne trichloramine in indoor swimming pools in Sweden.

Trichloramine is a disinfection by-product in chlorinated swimming pools. It can evaporate into the air and irritate eyes and airways among swimmers and pool workers. This study aimed to evaluate airborne concentrations of trichloramine in different types of indoor swimming pools.

Non-surgical treatment of lateral malleolar fractures is safe: long-term follow-up of a comprehensive treatment algorithm.

Introduction: A study at Sahlgrenska University Hospital (SU) found significant variation in the treatment of ankle fractures, leading to the development of a structured treatment algorithm (TA). The TA aimed to standardise treatment and reduce the number of unnecessary surgical procedures. A follow-up study concluded that the number of surgeries had significantly decreased since the TA was introduced.

An Ontology to Bridge the Clinical Management of Patients and Public Health Responses for Strengthening Infectious Disease Surveillance: Design Science Study.

Background: Novel surveillance approaches using digital technologies, including the Internet of Things (IoT), have evolved, enhancing traditional infectious disease surveillance systems by enabling real-time detection of outbreaks and reaching a wider population. However, disparate, heterogenous infectious disease surveillance systems often operate in silos due to a lack of interoperability. As a life-changing clinical use case, the COVID-19 pandemic has manifested that a lack of interoperability can severely inhibit public health responses to emerging infectious diseases.

Can large language models help predict results from a complex behavioural science study?

We tested whether large language models (LLMs) can help predict results from a complex behavioural science experiment. In study 1, we investigated the performance of the widely used LLMs GPT-3.5 and GPT-4 in forecasting the empirical findings of a large-scale experimental study of emotions, gender, and social perceptions.

Plasma markers of neurodegeneration, latent cognitive abilities and physical activity in healthy aging.

Blood-based biomarkers of neurodegeneration demonstrate great promise for the diagnosis and prognosis of Alzheimer's disease. Ultra-sensitive plasma assays now allow for quantification of the lower concentrations in cognitively unimpaired older adults, making it possible to investigate whether these markers can provide insight also into the early neurodegenerative processes that affect cognitive function and whether the markers are influenced by modifiable risk factors. Adopting an exploratory approach in 93 healthy older adults (65-75 years), we used structural equation modelling to investigate cross-sectional associations between multiple latent cognitive abilities (working memory, episodic memory, spatial and verbal reasoning) and plasma amyloid beta (Aβ42/Aβ40 ratio), phosphorylated-tau 181 (ptau-181), glial fibrillary acidic protein (GFAP), and neurofilament light (NfL), as well as the influence of device-measured habitual physical activity on these associations.

Unique Lessons From the Natural Progression of Rejection in Human Uterine Allografts.

Introduction: Uterus transplantation (UTx) is a novel treatment for absolute uterine infertility. Acute T cell-mediated rejection (TCMR) can be monitored only through serial cervical biopsies.

Methods: This study, the first of its kind in human transplantation, evaluated clinical, serological, and pathophysiological manifestations of allograft rejection from immunosuppression withdrawal (ISW) to graft hysterectomy (Hx).

Uterus Transplant in Women With Absolute Uterine-Factor Infertility.

Importance: Uterus transplant in women with absolute uterine-factor infertility offers the possibility of carrying their own pregnancy.

Objective: To determine whether uterus transplant is feasible and safe and results in births of healthy infants.

Design, Setting, And Participants: A case series including 20 participants with uterine-factor infertility and at least 1 functioning ovary who underwent uterus transplant in a large US tertiary care center between September 14, 2016, and August 23, 2019.

High rate of gene family evolution in proximity to the origin of ectomycorrhizal symbiosis in Inocybaceae.

The genomes of ectomycorrhizal (ECM) fungi have a reduced number of genes encoding Carbohydrate-Active EnZymes (CAZymes), expansions in transposable elements (TEs) and small secreted proteins (SSPs) compared with saprotrophs. Fewer genes for specific peptidases and lipases in ECM fungi are also reported. It is unclear whether these changes occur at the shift to the ECM habit or are more gradual throughout the evolution of ECM lineages.

Heterogeneity in effect size estimates.

A typical empirical study involves choosing a sample, a research design, and an analysis path. Variation in such choices across studies leads to heterogeneity in results that introduce an additional layer of uncertainty, limiting the generalizability of published scientific findings. We provide a framework for studying heterogeneity in the social sciences and divide heterogeneity into population, design, and analytical heterogeneity.

Robotic Living Donor Hysterectomy for Uterus Transplantation: An Update on Donor and Recipient Outcomes.

Uterus transplantation (UTx) has evolved into a clinical reality for women with absolute uterine infertility. The international experience with UTx has predominantly utilized living donor grafts-and strategies to minimize harm to donors remain paramount. Robotic living donor hysterectomy represents a minimally invasive approach to facilitate rapid donor recovery, improve pelvic visualization and operative access, and maintain UTx recipient outcomes.

NMNAT2 is a druggable target to drive neuronal NAD production.

Maintenance of NAD pools is critical for neuronal survival. The capacity to maintain NAD pools declines in neurodegenerative disease. We identify that low NMNAT2, the critical neuronal NAD producing enzyme, drives retinal susceptibility to neurodegenerative insults.
