Alteplase Purge Solution for Impella 5.5 Ventricular Assist Device Purge System Occlusion: Case Report and Review of the Literature.

The use of an alteplase (Activase) purge solution to address Impella ventricular assist device "thrombosis" or "purge system occlusion" has been mainly documented with earlier generation Impella devices (CP, 2.5, 5.0).

RELMβ sets the threshold for microbiome-dependent oral tolerance.

Tolerance to dietary antigens is critical for avoiding deleterious type 2 immune responses resulting in food allergy (FA) and anaphylaxis. However, the mechanisms resulting in both the maintenance and failure of tolerance to food antigens are poorly understood. Here we demonstrate that the goblet-cell-derived resistin-like molecule β (RELMβ) is a critical regulator of oral tolerance.

ChatGPT Assisting Diagnosis of Neuro-Ophthalmology Diseases Based on Case Reports.

Background: To evaluate the accuracy of Chat Generative Pre-Trained Transformer (ChatGPT), a large language model (LLM), to assist in diagnosing neuro-ophthalmic diseases based on case reports.

Methods: We selected 22 different case reports of neuro-ophthalmic diseases from a publicly available online database. These cases included a wide range of chronic and acute diseases commonly seen by neuro-ophthalmic subspecialists.

Childhood adversity and late-life cognitive and brain health in a diverse cohort.

Introduction: Childhood adversity harms neurodevelopment. Literature on late-life brain health is limited, and findings on late-life cognition are mixed.

Methods: Pooling data from Kaiser Healthy Aging and Diverse Life Experiences (KHANDLE) and Study of Healthy Aging in African Americans (STAR) cohorts, we assessed the impact of childhood adversity (factor score from seven self-reported items) on (a) executive function and verbal memory decline using linear mixed effects models (n = 2447), (b) structural magnetic resonance imaging (MRI) using linear regression (n = 618), and (c) amyloid positron emission tomography (PET) using generalized linear models (n = 331), all adjusting for early-life demographic and socioeconomic confounders.

Regulation loopholes in China aggravate depletion of wildlife.

China has committed to develop an ecological civilization and recently taken significant steps to enhance conservation measures including updating the List of National Key Protected Wild Animals and revising the Wildlife Protection Law in 2021. Conservation has improved by increasing the number of protected species. However, a notable shortcoming undermines the effectiveness of protection for as many as 87 species, as the regulation applies only to wild and not to captive individuals (Figure 1 and Table S1).

Tobacco Use, Food Insecurity, and Low BMI in India's Older Population.

Background: Underweight is a prevalent condition among older adults in developing countries and poses a substantial burden on health, social, and aged-care systems. In this study, we examined the influence of tobacco use and food insecurity on the risk of being underweight among adults aged 60 or older in India.

Methods: We used data from the 2017-2018 Longitudinal Aging Study in India.

UK Foot and Ankle Thromboembolism (UK-FATE).

Aims: Venous thromboembolism (VTE) is a potential complication of foot and ankle surgery. There is a lack of agreement on contributing risk factors and chemical prophylaxis requirements. The primary outcome of this study was to analyze the 90-day incidence of symptomatic VTE and VTE-related mortality in patients undergoing foot and ankle surgery and Achilles tendon (TA) rupture.

Notch4 regulatory T cells and SARS-CoV-2 viremia shape COVID19 survival outcome.

Background: Immune dysregulation and SARS-CoV-2 plasma viremia have been implicated in fatal COVID-19 disease. However, how these two factors interact to shape disease outcomes is unclear.

Methods: We carried out viral and immunological phenotyping on a prospective cohort of 280 patients with COVID-19 presenting to acute care hospitals in Boston, Massachusetts and Genoa, Italy between June 1, 2020 and February 8, 2022.

Biochemical Characterization of Recombinant EntV Peptide to Elucidate Its Antihyphal and Antifungal Mechanisms against .

is a common opportunistic fungus in humans, whose morphological switch between yeast and hyphae forms represents a key virulence trait. Developing strategies to inhibit hyphal growth may provide insights into designs of novel antivirulent therapeutics. Importantly, the gut commensal bacterium, , secretes a bacteriocin EntV which has potent antivirulent and antifungal effects against in infection models; however, hampered by the challenges to access large quantities of bioactive EntV, the detailed understanding of its mechanisms on has remained elusive.

Social and physical environment effects on toileting disability among older adults in India.

Background: To examine the prevalence of toileting disability among older adults in India and its association with broad aspects of the physical and social environment.

Methods: We use data from the inaugural wave of the Longitudinal Ageing Study in India and focus on adults aged 65 and older (N = 20,789). We draw on the disablement process model and existing frameworks to identify environmental factors and other risk factors that may be associated with toileting disability.

Circulating extracellular vesicular microRNA signatures in early gestation show an association with subsequent clinical features of pre-eclampsia.

In a prospective cohort of subjects who subsequently developed preeclampsia (PE, n = 14) versus remaining healthy (NORM, n = 12), early gestation circulating extracellular vesicles (EVs) containing a panel of microRNA signatures were characterized and their biological networks of targets deciphered. Multiple microRNAs of which some arose from the placenta (19MC and 14MC) demonstrated changes in association with advancing gestation, while others expressed were pathognomonic of the subsequent development of characteristic clinical features of PE which set in as a late-onset subtype. This panel of miRNAs demonstrated a predictability with an area under the curve of 0.

Expansion of Auxiliary Activity Family 5 sequence space via biochemical characterization of six new copper radical oxidases.

Bacterial and fungal copper radical oxidases (CROs) from Auxiliary Activity Family 5 (AA5) are implicated in morphogenesis and pathogenesis. The unique catalytic properties of CROs also make these enzymes attractive biocatalysts for the transformation of small molecules and biopolymers. Despite a recent increase in the number of characterized AA5 members, especially from subfamily 2 (AA5_2), the catalytic diversity of the family as a whole remains underexplored.

Are Pre-clerkship Remediation, Grading, and Reporting Practices Equitable in the U.S.? A National Survey.

With the proliferation of pass/fail grading practices in the pre-clerkship phase of undergraduate medical education, questions arise about the transparency and variability of grading and grade reporting practices, raising issues of equity in assessment, particularly regarding residency matching. The purpose of this survey was to determine the remediation and academic performance reporting practices of United States (U.S.

Emotional responses and psychological health among young people amid climate change, Fukushima's radioactive water release, and wars in Ukraine and the Middle East, and the mediating roles of media exposure and nature connectedness: a cross-national analysis.

Background: New global crises are emerging, while existing global crises remain unabated. Coping with climate change, the radioactive water released into the Pacific Ocean subsequent to the Fukushima nuclear accident in Japan, and the wars in Ukraine and the Middle East (hereafter referred to as the wars) as individual crises can negatively affect the psychological health of young people, but little is known about the compounded impact of multiple crises. We aimed to examine: (1) the emotional responses of young people towards each individual crisis, (2) how aggregate levels of emotional engagement in global crises might pose different potential trajectories in psychological health, and (3) the protective or exacerbating role of media exposure and nature connectedness as mediators on psychological health outcomes of young people.
