Seven-year performance of a clinical metagenomic next-generation sequencing test for diagnosis of central nervous system infections.

Metagenomic next-generation sequencing (mNGS) of cerebrospinal fluid (CSF) is an agnostic method for broad-based diagnosis of central nervous system (CNS) infections. Here we analyzed the 7-year performance of clinical CSF mNGS testing of 4,828 samples from June 2016 to April 2023 performed by the University of California, San Francisco (UCSF) clinical microbiology laboratory. Overall, mNGS testing detected 797 organisms from 697 (14.

Laboratory validation of a clinical metagenomic next-generation sequencing assay for respiratory virus detection and discovery.

Tools for rapid identification of novel and/or emerging viruses are urgently needed for clinical diagnosis of unexplained infections and pandemic preparedness. Here we developed and clinically validated a largely automated metagenomic next-generation sequencing (mNGS) assay for agnostic detection of respiratory viral pathogens from upper respiratory swab and bronchoalveolar lavage samples in <24 h. The mNGS assay achieved mean limits of detection of 543 copies/mL, viral load quantification with 100% linearity, and 93.

Concussion Reduction in Division I and II Athletes: Effects of Simple Cervical Spine Exercise Regimen.

Introduction:  Primary preventative medicine lacks a consensus on effective concussion prevention strategies for collegiate athletes. Cervical strength has been identified as a potential factor in concussion risk reduction. This study evaluates the impact of a commercially available, portable cervical muscle stretching and strengthening device, NeckX®, on cervical strength, range of motion (ROM), and concussion incidence in collegiate athletes participating in high-concussion-risk sports.

Chagas Disease Diagnostic Practices at Four Major Hospital Systems in California and Texas.

Background: Chagas disease (CD) is a parasitic disease that affects ∼300 000 people living in the United States. CD leads to cardiac and/or gastrointestinal disease in up to 30% of untreated people. However, end-organ damage can be prevented with early diagnosis and antiparasitic therapy.

Autistic People and Moving Home: A Systematic Review.

Background: While many studies have examined where and with whom autistic people live, very few have looked at autistic people's experience of moving home. Choosing where to live, and being able to move residence, could be important for autonomy, and we therefore undertook a systematic review to identify studies about autistic adults' experience of moving home.

Methods: We entered search terms relevant to autism and moving home into six databases and Google Scholar.

The United Kingdom Eating Disorders Genetics Initiative.

Objective: The United Kingdom Eating Disorders Genetics Initiative (EDGI UK), part of the National Institute for Health and Care Research (NIHR) Mental Health BioResource, aims to deepen our understanding of the environmental and genetic etiology of eating disorders. EDGI UK launched in February 2020 and is partnered with the UK eating disorders charity, Beat. Multiple EDGI branches exist worldwide.

Sociodemographic, mental health, and physical health factors associated with participation within re-contactable mental health cohorts: an investigation of the GLAD Study.

Background: The Genetic Links to Anxiety and Depression (GLAD) Study is a large cohort of individuals with lifetime anxiety and/or depression, designed to facilitate re-contact of participants for mental health research. At the start of the pandemic, participants from three cohorts, including the GLAD Study, were invited to join the COVID-19 Psychiatry and Neurological Genetics (COPING) study to monitor mental and neurological health. However, previous research suggests that participation in longitudinal studies follows a systematic, rather than random, process, which can ultimately bias results.

The network structure of mania symptoms differs between people with and without binge eating.

Objectives: People with bipolar disorder who also report binge eating have increased psychopathology and greater impairment than those without binge eating. Whether this co-occurrence is related to binge eating as a symptom or presents differently across full-syndrome eating disorders with binge eating is unclear.

Methods: We first compared networks of 13 lifetime mania symptoms in 34,226 participants from the United Kingdom's National Institute for Health and Care Research BioResource with (n = 12,104) and without (n = 22,122) lifetime binge eating.

Retrospective analysis of whole-body cryotherapy adverse effects in Division I collegiate athletes.

Context: Although the physiological effects and the performance of athletes after utilizing whole-body cryotherapy (WBC) have been widely studied, there is a lack of data on its adverse effects. It is important to be aware of the adverse effects of any treatment for its use to be properly recommended.

Objectives: This study aims to provide insight to any adverse effects that collegiate athletes experienced after utilizing WBC to better utilize this therapeutic modality.

Development of a Shelter-based Health Empowerment Program for Pregnant and Parenting Youth Experiencing Homelessness.

Background: Pregnancy and parenthood are common among youth experiencing homelessness and are associated with significant health risk for both parent and child. Yet, little is known regarding how to best promote health among this vulnerable population.

Objectives: To understand stakeholder perceptions of needs and factors required for successful implementation of a shelter-based health empowerment program for pregnant and parenting youth experiencing homelessness and their children.

Risk and protective factors for new-onset binge eating, low weight, and self-harm symptoms in >35,000 individuals in the UK during the COVID-19 pandemic.

Objective: The disruption caused by the COVID-19 pandemic has been associated with poor mental health, including increases in eating disorders and self-harm symptoms. We investigated risk and protective factors for the new onset of these symptoms during the pandemic.

Method: Data were from the COVID-19 Psychiatry and Neurological Genetics study and the Repeated Assessment of Mental health in Pandemics Study (n = 36,715).

Corticotropin Releasing Factor (CRF) Coexpression in GABAergic, Glutamatergic, and GABA/Glutamatergic Subpopulations in the Central Extended Amygdala and Ventral Pallidum of Young Male Primates.

The central extended amygdala (CEA) and ventral pallidum (VP) are involved in diverse motivated behaviors based on rodent models. These structures are conserved, but expanded, in higher primates, including human. Corticotropin releasing factor (CRF), a canonical "stress molecule" associated with the CEA and VP circuitry across species, is dynamically regulated by stress and drugs of abuse and misuse.

Unbiased Stereological Estimates of Dopaminergic and GABAergic Neurons in the A10, A9, and A8 Subregions in the Young Male Macaque.

The ventral midbrain is the primary source of dopamine- (DA) expressing neurons in most species. GABA-ergic and glutamatergic cell populations are intermixed among DA-expressing cells and purported to regulate both local and long-range dopamine neuron activity. Most work has been conducted in rodent models, however due to evolutionary expansion of the ventral midbrain in primates, the increased size and complexity of DA subpopulations warrants further investigation.

Predicting Forefoot-Orthosis Interactions in Rheumatoid Arthritis Using Computational Modelling.

Foot orthoses are prescribed to reduce forefoot plantar pressures and pain in people with rheumatoid arthritis. Computational modelling can assess how the orthoses affect internal tissue stresses, but previous studies have focused on a single healthy individual. This study aimed to ascertain whether simplified forefoot models would produce differing biomechanical predictions at the orthotic interface between people with rheumatoid arthritis of varying severity, and in comparison to a healthy control.

Perigenual and Subgenual Anterior Cingulate Afferents Converge on Common Pyramidal Cells in Amygdala Subregions of the Macaque.

The subgenual (sgACC) and perigenual (pgACC) anterior cingulate are important afferents of the amygdala, with different cytoarchitecture, connectivity, and function. The sgACC is associated with arousal mechanisms linked to salient cues, whereas the pgACC is engaged in conflict decision-making, including in social contexts. After placing same-size, small volume tracer injections into sgACC and pgACC of the same hemisphere in male macaques, we examined anterogradely labeled fiber distribution to understand how these different functional systems communicate in the main amygdala nuclei at both mesocopic and cellular levels.

The Role of Topical Anesthetics in the Treatment of Pediatric Facial Lacerations.

Purpose: Pediatric facial lacerations (PLACS) are a common emergency, often requiring a general anesthetic (GA) or sedation if infiltration of local anesthetic (LA) cannot be tolerated. Topical anesthetics are a well-established and accepted alternative to infiltrations for facial lacerations which can reduce the need for general anesthesia. We report our experience following the introduction of topical 5% cocaine w/v and 1:2000 adrenaline gel (TCA) in a single center.

Primary Renal Carcinoid: Two Rare Cases at a Single Center.

Renal carcinoid tumors are exceedingly rare. These neuroendocrine masses are most frequently found in the gastrointestinal and respiratory tracts. A renal carcinoid tumor has only been documented in around 100 cases.

Comparative Performance of Latest-Generation and FDA-Cleared Serology Tests for the Diagnosis of Chagas Disease.

Confirmed diagnosis of chronic Chagas disease (CD) requires positive results by two different IgG serology tests. Variable sensitivity has been reported among tests and in different geographic regions. Inadequate specificity presents a particular challenge in low-prevalence settings such as the United States.

Multiple idiopathic cervical root resorption: Case report of an unusual presentation.

Idiopathic cervical root resorption (ICRR) is a rare condition involving the cemento-enamel junction of the teeth. Multiple idiopathic cervical root resorption (MICRR) involves several teeth with an unknown prevalence and aetiology. The resorptive lesions are often detected on routine radiographs or during clinical examination.

A 22-Year-Old Retained Ureteral Stent: One of the Oldest Removed Using a Multimodal Endourologic Approach.
