Successful Invasion Into New Environments Without Evidence of Rapid Adaptation by a Predatory Marine Gastropod.

Invasive species with native ranges spanning strong environmental gradients are well suited for examining the roles of selection and population history in rapid adaptation to new habitats, providing insight into potential evolutionary responses to climate change. The Atlantic oyster drill (Urosalpinx cinerea) is a marine snail whose native range spans the strongest coastal latitudinal temperature gradient in the world, with invasive populations established on the US Pacific coast. Here, we leverage this system using genome-wide SNPs and environmental data to examine invasion history and identify genotype-environment associations indicative of local adaptation across the native range, and then assess evidence for allelic frequency shifts that would signal rapid adaptation within invasive populations.

Global mental health solidarity: strategies and solutions.

Mental health is deteriorating far and fast globally post-COVID. Though there were already over one billion people living with mental disorders pre-pandemic, in the first year of COVID-19 alone, the prevalence of anxiety and depression soared by 25% worldwide. In light of the chronic shortages of mental health resources and talents, along with disruptions of available health services caused by pandemic-related restrictions, technology is widely believed to hold the key to addressing the rising mental health crises.

The impact of gastroesophageal reflux disease on upper esophageal sphincter function: Insights from PH impedance and high-resolution manometry.

Lower esophageal sphincter (LES) pathophysiology has been established in gastroesophageal reflux disease (GERD); however, less is understood regarding the role the upper esophageal sphincter (UES) plays in preventing laryngopharynphageal reflux. Sustained UES basal pressure prevents reflux into the pharynx while allowing relaxation during ingestion. We investigate whether GERD influences UES function via HRM and pH Impedance testing.

Is Obesity a Risk Factor for Disorders of Amniotic Fluid?

Objectives: Prior studies show conflicting evidence as to whether obesity in the absence of other medical or pregnancy-related conditions contributes to amniotic fluid disorders. The purpose of this study is to determine the association between late-pregnancy obesity with oligohydramnios (amniotic fluid index [AFI] ≤5 cm or maximum vertical pocket [MVP] <2 cm) and/or polyhydramnios (AFI ≥24 cm or MVP ≥8 cm).

Methods: This is a retrospective cohort study of 961 women with singleton gestations who had one or more obstetrical ultrasounds at a single institution at 36 0/7 weeks gestation or beyond between August 1, 2015, and May 1, 2020.

Atypical Intrahepatic Cholestasis of Pregnancy: A Red Herring.

Intrahepatic cholestasis of pregnancy is an intrahepatic etiology of acute cholestasis commonly defined by pruritus and increased bile acids, liver transaminases, and, occasionally, bilirubin. Azathioprine is an immunosuppressive agent associated with various forms of hepatoxicity, ranging from transient rises in serum aminotransferase levels, acute cholestatic injury, and chronic hepatic injury. In this report, we present a 20-year-old pregnant woman who presented with cholestatic liver injury due to intrahepatic cholestasis of pregnancy with a clinical picture complicated by increased levels of azathioprine metabolites.

Where should "Humans" be in "One Health"? Lessons from COVID-19 for One Health.

The culling of animals that are infected, or suspected to be infected, with COVID-19 has fuelled outcry. What might have contributed to the ongoing debates and discussions about animal rights protection amid global health crises is the lack of a unified understanding and internationally agreed-upon definition of "One Health". The term One Health is often utilised to describe the imperative to protect the health of humans, animals, and plants, along with the overarching ecosystem in an increasingly connected and globalized world.

R2DRV: study protocol for longitudinal assessment of driving after mild TBI in young drivers.

Background: Mild traumatic brain injury (mTBI) and traffic-related injuries are two major public health problems disproportionately affecting young people. Young drivers, whose driving skills are still developing, are particularly vulnerable to impaired driving due to brain injuries. Despite this, there is a paucity of research on how mTBI impacts driving and when it is safe to return to drive after an mTBI.

A National Survey on the Relationship of Youth Sport Specialization Behaviors to Self-Reported Anxiety and Depression in Youth Softball Players.

Background: There are little to no data on whether any associations exist between sport specialization and mental health in youth softball athletes.

Hypothesis: Highly specialized youth softball athletes will have worse self-reported depression and anxiety symptom scores compared with low and moderate specialized athletes.

Study Design: Cross-sectional survey.

Clinical outcomes of long-term transmural drainage with double pigtail stents in disconnected pancreatic duct syndrome.

Background: Disconnected pancreatic duct syndrome (DPDS) is a common cause of recurrent pancreatic fluid collections (PFCs), often requiring repeat drainage. Following initial drainage with lumen apposing metal stents (LAMS), replacement with transmural double pigtail stents (DPS) has been shown to be a viable drainage modality mitigating the risk of recurrence. The sparsity of literature on the consequences of this strategy requires further investigation.

Nannies Go Rogue? A Call for Research into Nanny-Induced Elderly Abuse in China.

Older people often face varied and vicious abuse from care workers. Situations are often more pronounced for older people who live with additional cognitive or physical difficulties, such as dementia and disabilities, the prevalence of which has been on the rise in China and elsewhere. Recent discoveries of elderly abuse in China, which span from alarming levels of verbal, physical, psychological, financial, to sexual abuse, are all caused by nannies or "bao mu".

Development of an Emergency Department Case Management Case-Finding Tool.

Purpose Of Study: Identifying emergency department (ED) patients who are at high risk for return visits is an important goal for case management to improve patient care. This quality improvement study describes the development and evaluation of the Emergency Department Case Management Priority Score (EDCMPS), an electronic medical record (EMR)-based "case-finding" system, and its ability to identify these high-risk patients. In addition, the authors present data about its acceptability among emergency department case managers (ED CMs).

The neuropeptidergic connectome of C. elegans.

Efforts are ongoing to map synaptic wiring diagrams, or connectomes, to understand the neural basis of brain function. However, chemical synapses represent only one type of functionally important neuronal connection; in particular, extrasynaptic, "wireless" signaling by neuropeptides is widespread and plays essential roles in all nervous systems. By integrating single-cell anatomical and gene-expression datasets with biochemical analysis of receptor-ligand interactions, we have generated a draft connectome of neuropeptide signaling in the C.

Adaptation of sea turtles to climate warming: Will phenological responses be sufficient to counteract changes in reproductive output?

Sea turtles are vulnerable to climate change since their reproductive output is influenced by incubating temperatures, with warmer temperatures causing lower hatching success and increased feminization of embryos. Their ability to cope with projected increases in ambient temperatures will depend on their capacity to adapt to shifts in climatic regimes. Here, we assessed the extent to which phenological shifts could mitigate impacts from increases in ambient temperatures (from 1.
