Background: Resident-focused curricula that support competency acquisition in concussion care are currently lacking. We sought to fill this gap by developing and evaluating Spiral Integrated Curricula (SIC) using the cognitive constructivism paradigm and the Utilization-Focused Evaluation (UFE) framework. The evidence-based curricula consisted of academic half-days (AHDs) and clinics for first- and second-year family medicine residents.

Background: SL-172154 is a hexameric fusion protein adjoining the extracellular domain of SIRPα to the extracellular domain of CD40L via an inert IgG-derived Fc domain. In preclinical studies, a murine equivalent SIRPα-Fc-CD40L fusion protein provided superior antitumor immunity in comparison to CD47- and CD40-targeted antibodies. A first-in-human phase I trial of SL-172154 was conducted in patients with platinum-resistant ovarian cancer.

North Carolina (NC) ranks third among US states in both hog production and hurricanes. NC's hogs are housed in concentrated animal feeding operations (CAFOs) in the eastern, hurricane-prone part of the state. Hurricanes can inundate hog waste lagoons, transporting fecal bacteria that may cause acute gastrointestinal illness (AGI).

Background: Yttrium-90 FF-21101 (Y-FF-21101) is a radiopharmaceutical that targets P-cadherin as a therapy against solid tumors. A previously reported, first-in-human study determined that a dose of 25 mCi/m was safe, and a patient with clear cell carcinoma of the ovary achieved a complete response. In this article, the authors report the results of Y-FF-21101 treatment in an ovarian carcinoma expansion cohort and in patients with selected solid tumors who had known high P-cadherin expression.

In socially monogamous species, sexual selection not only depends on initial mate choice but also mate switching. To date, studies lack assessment of (1) differences between passive (widowhood) and active (divorce) mate switching, (2) longer term fitness consequences (beyond the season post-divorce) and (3) how age masks reproductive costs and benefits of divorce. We investigated causes and short- and long-term consequences of mate switching and their age dependence using longitudinal data on Seychelles warblers (Acrocephalus sechellensis).

This Health Policy examines the relationship between child cash benefits and child health, with the goal of informing future policy development in the USA. As of 2024, more than 140 countries have adopted large-scale, government-funded child cash transfer programmes. High-income countries more often adopt universal or near universal programmes, while lower-income countries often impose means tests or condition benefits on specific behaviours.

Introduction: The GENCOV study sought to evaluate serological differences between individuals with differing COVID-19 severity and outcomes. We assessed the SARS-CoV-2 antibody response of GENCOV participants cross-sectionally 1-, 6-, and 12-months following COVID-19 diagnosis to identify patient factors associated with more robust and durable humoral immune responses.

Materials And Methods: COVID-19 patients and a control cohort of vaccinated infection-naïve participants were recruited at hospital sites across the Greater Toronto Area in Ontario, Canada.

Article Synopsis
  • Benzene is linked to human carcinogenicity, notably causing acute myeloid leukemia, with limited evidence for lung cancer connections.
  • A systematic review and meta-analysis were conducted on occupational benzene exposure and lung cancer risk, involving 13 studies with over 366,000 participants.
  • Results indicated a slight elevation in lung cancer risk associated with occupational benzene exposure, with higher risks observed in well-exposed, high-quality studies that included both genders, concluding that there is a positive association between benzene exposure and lung cancer risk.

Background: Coal mining involves heavy physical demand, which is associated with increased risk of injury and long-term musculoskeletal health disorders and chronic pain. Management of chronic or recurrent pain is in turn associated with prescription opioid use and risk of opioid use disorder (OUD).

Methods: We analyzed clinical data from 5463 coal miners evaluated between 2004 and 2015.

Article Synopsis
  • * The timing of ice-off has become much more variable, influenced significantly by spring air temperatures and snowfall, leading to a reduction in total ice duration by about a month.
  • * Changes in ice phenology result in less winter inverse stratification, causing a longer spring mixing period, challenging the assumptions based on traditional ice clearance dates regarding under-ice thermal dynamics.

The International Nuclear Workers Study (INWORKS) contributes knowledge on the dose-response association between predominantly low dose, low dose rate occupational exposures to penetrating forms of ionizing radiation and cause-specific mortality. By extending follow-up of 309,932 radiation workers from France (1968-2014), the United Kingdom (1955-2012), and the United States (1944-2016) we increased support for analyses of temporal variation in radiation-cancer mortality associations. Here, we examine whether age at exposure, time since exposure, or attained age separately modify associations between radiation and mortality from all solid cancers, solid cancers excluding lung cancer, lung cancer, and lymphohematopoietic cancers.

Workers regularly using vibrating hand tools may develop a disorder referred to as hand-arm vibration syndrome (HAVS). HAVS is characterized by cold-induced vasospasms in the hands and fingers that result in blanching of the skin, loss of sensory function, pain, and reductions in manual dexterity. Exposure to vibration induces some of these symptoms.

Invasions by nonnative insect species can massively disrupt ecological processes, often leading to serious economic impacts. Previous work has identified propagule pressure as important driver of the trend of increasing numbers of insect invasions worldwide. In the present article, we propose an alternative hypothesis-that insect invasions are being driven by the proliferation of nonnative plants, which create niches for insect specialists and facilitate their establishment outside their native ranges where their hosts are planted or are invasive.

Unlabelled: Dispersal is an important behavior in many animals, with profound effects on individual fitness and the evolutionary trajectories of populations. This is especially true within taxa with particular life-history strategies, for example those that exploit ephemeral habitat. Further, dispersal is commonly seen to be part of behavioral syndromes - suites of traits that covary across behavioral contexts.

Divorce-terminating a pair bond whilst both members are alive-is a mating strategy observed in many socially monogamous species often linked to poor reproductive success. As environmental factors directly affect individual condition and reproductive performance, they can indirectly influence divorce. Given current climate change, understanding how environmental fluctuations affect partnership stability has important implications, including for conservation.
