Surgery for Olecranon Fractures in the Elderly (SOFIE): Results of the SOFIE Randomized Controlled Trial.

Background: The financial and resource burden of management of olecranon fractures in the elderly is likely to increase with an aging population. There is limited evidence guiding treatment choice in this cohort. This study aimed to determine whether operative treatment of displaced olecranon fractures in elderly patients provides superior 12-month functional outcomes compared to nonoperative treatment.

Genetic and environmental influences on alcohol consumption in middle to late life.

Objective: Alcohol use is common in older adults and linked to poor health and aging outcomes. Studies have demonstrated genetic and environmental contributions to the quantity of alcohol consumption in mid-to-late life, but less is known about whether these influences are moderated by sociodemographic factors such as age, sex, and educational attainment. This study sought to better understand sociodemographic trends in alcohol consumption across the second half of the life course and their underlying genetic and environmental influences.

This review synthesises recent advancements in the engineering of MoS to enhance its electrocatalytic properties. It focuses on strategies for designing an unsaturated electronic structure on metal catalytic centers and their role in boosting the efficiency of the hydrogen evolution reaction (HER).

The Association Between Delaying Anterior Cruciate Ligament Reconstruction in Adolescents and Increasing Meniscal and Chondral Pathology: A Cohort Study of 2740 Adolescents.

Background: A growing body of evidence surrounds secondary meniscal and cartilage pathology after delay to anterior cruciate ligament (ACL) reconstruction (ACLR). Many of these studies focus on or include an adult population.

Purpose: To elucidate the prevalence of secondary meniscal and chondral pathology with delay to ACLR in the adolescent population as well as examine the influence of sex, skeletal maturity, and trends over the years.

Discrimination of Healthy and -Infected Grapes Using Untargeted Metabolomic Analysis with Direct Electrospray Ionization Mass Spectrometry.

infections of grapes significantly reduce yield and quality and increase phenolic compound oxidation, resulting in color loss, off-flavors, and odors in wine. In this study, metabolites were extracted from grape homogenates comprising healthy or infected grapes from different vintages, cultivars, regions, and maturity stages. Samples were randomly analyzed by direct injection into an ion trap mass spectrometer, with data collected from 50 to 2000 / for 1 min.

Affinity maturation endows potent activity onto class 6 SARS-CoV-2 broadly neutralizing antibodies.

The emergence of SARS-CoV-2 variants of concern (VOCs) has greatly diminished the neutralizing activity of previously FDA-approved monoclonal antibodies (mAbs), including that of antibody cocktails and of first-generation broadly neutralizing antibodies such as S309 (Sotrovimab). In contrast, antibodies targeting cryptic conformational epitopes of the receptor binding domain (RBD) have demonstrated broad activity against emerging variants, but exert only moderate neutralizing activity, which has so far hindered clinical development. Here, we utilize in vitro display technology to identify and affinity-mature antibodies targeting the cryptic class 6 epitope, accessible only in the "up" conformation of the SARS-CoV-2 spike trimer.

Exposure therapy consortium: Outcomes of the proof-of-principle study.

Background: This paper reports on the outcomes of a proof-of-principle study for the Exposure Therapy Consortium, a global network of researchers and clinicians who work to improve the effectiveness and uptake of exposure therapy. The study aimed to test the feasibility of the consortium's big-team science approach and test the hypothesis that adding post-exposure processing focused on enhancing threat reappraisal would enhance the efficacy of a one-session large-group interoceptive exposure therapy protocol for reducing anxiety sensitivity.

Methods: The study involved a multi-site cluster-randomized controlled trial comparing exposure with post-processing (ENHANCED), exposure without post-processing (STANDARD), and a stress management intervention (CONTROL) in students with elevated anxiety sensitivity.

Disinformation and calculated care beyond the Global North: comparing refugee discourses in Australia and India.

This article explores what "care" looks like in the specific context of Muslim refugees and asylum seekers within the dominant discourse of humanitarianism. India and Australia are chosen for this comparative analysis because our aim is to emphasise multidimensional anti-Muslim alliances that are now in place in both contexts between the governments and official and unofficial media that influence humanitarian policies and practice. We argue that the "information disorder" that dominates current media ecologies about Muslim refugees in both countries is produced at this nexus of official agents-both state and media institutions-as well as social media content produced by local and global actors that perpetuate anti-Muslim bias.

From banks to burrows: Habitat preferences and nesting behaviours of platypuses in the Snowy River.

Platypuses are a unique freshwater mammal native to eastern Australia. They are semi-aquatic, predominantly nocturnal, and nest in burrows dug into the banks of waterbodies. Quantifying nesting burrow characteristics is challenging due to the species' cryptic nature.

Can sexual conflict drive transitions to asexuality? Female resistance to fertilization in a facultatively parthenogenetic insect.

Facultatively parthenogenetic animals could help reveal the role of sexual conflict in the evolution of sex. Although each female can reproduce both sexually (producing sons and daughters from fertilized eggs) and asexually (typically producing only daughters from unfertilized eggs), these animals often form distinct sexual and asexual populations. We hypothesized that asexual populations are maintained through female resistance as well as the decay of male traits.

Home delivery and associated factors among women who gave birth after antenatal care follow-up in the last 6 months in Jabitehnan District, Northwest Ethiopia: mixed community-based study.

Introduction: Maternal mortality is a global issue, with developing countries accounting for over 99% of maternal deaths, with 30% of Ethiopian mothers dying from pregnancy-related causes. This study aimed to assess the magnitude, associated factors, and reasons for home delivery among women who gave birth after antenatal care follow-up in the last 6 months in Jabitehnan District, Northwest Ethiopia.

Methods: A mixed community-based study was conducted on women who gave birth after antenatal care follow-up in the last 6 months.

Smokeless tobacco (snuff) and site-specific cancer risks in adult Black South African women: Findings from the Johannesburg Cancer Study.

Smokeless tobacco (SLT) use is an established carcinogen to the nasal cavity, lip, and oropharynx, however, few studies have examined cancer risks in older African women among whom SLT use is common. We investigated snuff use and the risk of site-specific cancers among 15,336 newly diagnosed female cancer patients in the Johannesburg Cancer Study, South Africa. We designed case-control comparisons across multiple cancer outcomes: (a) known SLT-associated cancers; (b) other tobacco-related cancers and (c) genital cancers owing to intravaginal snuff use.

Extensive Tracking of Nomadic Waterbird Movements Reveals an Inland Flyway.

Waterbirds are highly mobile and have the ability to respond to environmental conditions opportunistically at multiple scales. Mobility is particularly crucial for aggregate-nesting species dependent on breeding habitat in arid and semi-arid wetlands, which can be ephemeral and unpredictable. We aimed to address knowledge gaps about movement routes for aggregate-nesting nomadic waterbird species by tracking them in numbers sufficient to make robust assessment of their movement patterns.

Serious games vs. traditional tutorials in the pandemic: a randomised controlled trial.

Background And Aim: The COVID-19 pandemic necessitated the transition to online medical education. This study evaluated the efficacy of online case-based tutorials using a serious game tutorial [PlayMed™ (PM)], as compared to a traditional slideshow tutorial (TT).

Methods: We performed a prospective, mixed-methods, randomised controlled trial on undergraduate medical students during the COVID-19 pandemic, from May 2020 to January 2021.

Age-related clonal hematopoiesis and HIV infection are associated with geriatric outcomes: The ARCHIVE study.

While HIV infection and clonal hematopoiesis (CH) have been linked with inflammatory dysregulation and an increased risk of aging-related comorbidities, their relationship with clinical geriatric syndromes has not been well defined. In the Age-related Clonal Haematopoiesis in an HIV Evaluation Cohort (ARCHIVE) study (NCT04641013), we measure associations between HIV and CH and geriatric syndromes. Of 345 participants (176 with HIV and 169 without HIV), 23% had at least one mutation associated with CH: 27% with HIV and 18% without HIV (p = 0.
