Purpose: In the setting of an established childhood pneumococcal vaccination programme with immediate initiation and treatment of antiretroviral therapy (ART) for people living with HIV (PLWH), the risk of adult pneumococcal community-acquired pneumonia (CAP) is not recently described. We aimed to investigate CAP incidence, recurrence, mortality, risk factors and microbiology before and during the COVID-19 pandemic.
Participants: Adults aged ≥18 years were enrolled in three South African provinces from March 2019 to October 2021, with a brief halt during the initial COVID-19 lockdown.
Background: Traumatic arteriovenous fistulas (AVFs) are rare entities, especially when referring to visceral arterioportal AVFs. Currently, there are no large epidemiological studies looking specifically at traumatic visceral AVFs. When traumatic AVFs have been discussed in the literature, it is in the form of case reports or case series and focused on peripheral AVFs.

We used adjusted Cox models to estimate the risk of incident PDD associated with demographic factors, clinical characteristics, and time-varying total ACB in a longitudinal, deeply-phenotyped prospective PD cohort.
Major Findings: 56.
Background: Serotype-specific urinary antigen detection (UAD) assay results can be used to estimate the serotype contribution among adults with pneumococcal community-acquired pneumonia (CAP) and to guide recommendations regarding higher-valency pneumococcal conjugate vaccines (PCVs).
Methods: Adults aged ≥18 years hospitalized with radiographic evidence of CAP were prospectively enrolled in 4 US cities from November 2019 to December 2020, overlapping the coronavirus disease 2019 (COVID-19) pandemic. Data were collected by patient interview and medical chart review.
The perception of objects is a challenging task that requires recognizing visual elements and integrating them into a whole. While human vision prioritizes attention to the overall configuration, data from other species suggests this bias towards global form perception is not universal. Studies with pigeons indicate preferential attention to local details when both local and global information may be diagnostic, but studies with other bird species are more limited.

Methods: This prospective trial enrolled participants aged 50 years and older who had a significant family history of cancer or a cancer-susceptibility gene variant. Participants underwent noncontrast WBM and MCED testing.
Background: Epidemiological studies have been inconsistent regarding an association between proton pump inhibitor (PPI) use and risk of primary cardiovascular disease (CVD) events.
Methods: We studied 85,189 postmenopausal women (mean age 63 years at baseline) without known CVD at enrollment into the Women's Health Initiative Observational Study (1993-1998). PPI use was determined from medication inventories at baseline and Year-3.
Background: Family environment plays a critical role in shaping stress response systems. Concordance between mothers' and children's physiological states, specifically their Respiratory Sinus Arrhythmia (RSA), reflects dyadic co-regulation. Negative or weakened RSA synchrony during interactions is linked to various psychosocial risks, but existing research has focused on risks in the mother or child as opposed to the dyad.

It occurs with severe neuropsychiatric symptoms that often improve with immunotherapy. Clinical studies and animal models based on patients' antibody transfer or NMDAR immunization suggest that the autoantibodies play a major pathogenic role.

Mule deer () were captured for various research projects and management actions in the Trans-Pecos and Panhandle regions of Texas from 2015 to 2019. The objective of this study was to develop hematologic and biochemical parameters for free-ranging mule deer in Texas and to develop a health monitoring system for current and future mule deer population management.

The objective of this study was to examine the association between anticholinergic exposure and white matter hyperintensity (WMH) burden.
Methods: This was a retrospective analysis of data from the Adult Changes in Thought (ACT) study, a prospective cohort study among adults aged ≥65 years on dementia risk factors.
Exposure to multiple environmental stressors is a common occurrence that can affect organisms in predictable or unpredictable ways. Hypoxia and turbidity in aquatic environments are 2 stressors that can affect reproductive behaviors by altering energy availability and the visual environment, respectively. Here we examine the relative effects of population and the rearing environment (oxygen concentration and turbidity) on reproductive behaviors.

This longitudinal study aims to assess the impact of positive changes from the pandemic on the association between COVID-related stressors and psychopathology before and after the start of the pandemic.
Methods: Seventy-five mothers from low income, economically marginalized backgrounds (mean age=30 years, 80 % Black) completed a pre-pandemic visit (T1;2015-2019) and an online survey (T2;2020-2021) mid-pandemic.
Leigh syndrome, a severe neurological disorder is commonly caused by homozygous or bi-allelic pathogenic variants in the SURF1 gene. SURF1 deficiency leads to dysfunction of Cytochrome C Oxidase (COX) activity, which is crucial for mitochondrial oxidative phosphorylation. Understanding COX activity's correlation with disease severity is essential for developing SURF1 Leigh Syndrome biomarkers.

However, the biological underpinnings driving these traits are not known. Given its role in regulating host metabolism in disease studies, we hypothesized that the gut microbiome contributes to variation in normal cross-vertebrate species differences in metabolism, including those associated with the brain's energetic requirements.

On human chromosome 15, the parental-specific expression of Prader-Willi Syndrome (PWS)-related genes, such as and , are regulated through the genetic imprinting of the PWS imprinting center (PWS-IC). On the paternal allele, PWS genes are expressed whereas the epigenetic maternal silencing of PWS genes is controlled by the EHMT2-mediated methylation of H3K9 in PWS-IC.

Methods: Abstracted data include medications; laboratory results; women's health; blood pressure; physical injuries; cardiovascular, neurological, psychiatric and other medical conditions.
The SLC6A1 gene encodes the gamma-aminobutyric acid (GABA) transporter GAT-1, the deficiency of which is associated with infantile encephalopathy with intellectual disability. We designed two AAV9 vectors, with either the JeT or MeP promoter, and conducted preclinical gene therapy studies using heterozygous and homozygous Slc6a1 KO mice at different developmental ages and various routes of administration. Neonatal intracerebroventricular administration of either vector resulted in significantly normalized EEG patterns in Slc6a1-/- or Slc6a1+/- mice, as well as improvement in several behavioral phenotypes of Slc6a1-/- mice.
