Autistic and transgender/gender diverse people's experiences of health and healthcare.

Background: Autistic people and transgender/gender diverse people experience poorer healthcare experiences and greater risk of diagnosed, suspected, and assessment recommended health conditions, compared to non-autistic and cisgender individuals, respectively. Despite this, there is a paucity of studies on the healthcare experiences and health outcomes of transgender/gender diverse autistic individuals.

Methods: We compared the healthcare experiences and health outcomes of cisgender autistic (n = 1094), transgender/gender diverse autistic (n = 174), and cisgender non-autistic adults (n = 1295) via an anonymous, self-report survey.

How do Early-career Biology Faculty Develop Pedagogical Content Knowledge? Exploring Variation and Longitudinal Development.

Active-learning instructors are more effective when they use pedagogical content knowledge (PCK) to anticipate, interpret, and respond to student thinking. PCK is topic-specific and includes knowledge of student thinking (e.g.

Quantifying capacity of otolaryngology-head and neck surgery in Zimbabwe.

Objectives: To evaluate the otolaryngology surgical capacity in Harare, Zimbabwe by analyzing procedural volumes across four hospitals, one private and three public, from 2019 to 2022.

Methods: A retrospective review of hand-written surgical case logs was conducted at Harare Eye, Ear, Nose, and Throat Institute (HEENT), Parirenyatwa Group of Hospitals (PGH), Sally Mugabe Children's Hospital (SMCH), and Sally Mugabe Adult's Hospital (SMAH). Patient age and surgical intervention for all otolaryngology surgeries performed in the operating room from 2019 to 2022 were recorded.

Drusen Regression after Macula-involving Rhegmatogenous Retinal Detachment Repair.

Purpose: To investigate the effect of macula-involving rhegmatogenous retinal detachment (RRD) repair on drusen regression.

Methods: A retrospective review was performed of patients with drusen who underwent macula-involving RRD repair. Longitudinal optical coherence tomography scans were reviewed by three graders, and each case was grouped into one of three categories: drusen regression, drusen persistence, or mixed.

Guidelines for Diagnosis of Noise-Induced Hearing Loss and Their Specificity.

Objectives: A recent paper by Moore, Lowe and Cox has proposed guidelines for diagnosing noise-induced hearing loss (NIHL). It is referred to here as the MLC guidelines. Our aim was to assess the specificity of those guidelines (i.

Novel ganglion cell marker B3GNT6: A step forward in Hirschsprung's disease diagnosis.

Hirschsprung's (HSCR) disease, also known as aganglionic megacolon, or congenital intestinal aganglionosis affects roughly 1 out of every 5000 newborns. It is a birth defect characterized by the partial or complete loss of ganglion cells in the myenteric and submucosal plexus of the distal intestine which leads to ineffective peristalsis, constipation, and obstruction. Clinical assessment and radiological observations might imply HSCR disease, but definitive diagnosis requires biopsy interpretation and confirmation of ganglion cell loss.

Case report: Treatment of non-medical tetrahydrocannabinol toxicosis with transmucosal cannabidiol-infused dissolving sheets in six dogs.

Increased cases of canine tetrahydrocannabinol (THC) toxicosis have been reported in North America in recent years. Cases are often evaluated on an emergency basis and treatment has relied upon supportive care which can be costly and prohibitive for some pet owners. The purpose of this report is to describe the clinical findings and outcomes in dogs with non-medical, presumptive THC toxicosis treated by administration of a cannibidiol (CBD)-infused transmucosal dissolving sheet.

Severe Exertional Rhabdomyolysis in a Healthy 24-Year-Old Woman: A Case Report and Review of Literature.

Rhabdomyolysis is characterized by the release of muscle cell components into circulation following muscle cell injury. Common causes include trauma and compression, exposure to drugs and toxins, and intense physical exercise. This study depicts a case of exercise-induced rhabdomyolysis following a cycling class.

Phase 2A Proof-of-Concept Double-Blind, Randomized, Placebo-Controlled Trial of Nicotinamide in Early Alzheimer Disease.

Background And Objectives: Nicotinamide is a coenzyme involved in cellular oxidation-reduction reactions that can inhibit Class III histone deacetylases (HDACs) or sirtuins. HDAC inhibition can affect numerous therapeutic pathways, including tau phosphorylation. We tested the hypothesis that nicotinamide treatment could reduce tau phosphorylation in early Alzheimer disease (AD).

Are We Missing Obstructive Sleep Apnea in Patients With Non-traumatic Subglottic Stenosis?

Objective: To investigate the association between subglottic stenosis (SGS) and obstructive sleep apnea (OSA).

Methods: This is a cross-sectional pilot cohort study conducted at a single tertiary academic center from 2022 to 2023. Subjects with non-traumatic SGS were recruited for enrollment.

Rings of Power: Controlling SOD Mimic Activity by the Addition of Pyridine Rings within the Pyridinophane Scaffold.

Superoxide dismutase enzymes are a major defense against superoxide, which is a potent reactive oxygen species. Misregulation of reactive oxygen species and subsequent neuronal damage are etiological hallmarks of neurodegenerative disease. Macrocyclic small molecules have offered inroads toward functional SOD1 mimics.

Heterotopic Gastric Mucosa in the Gallbladder: A Rare Case and Differential Diagnosis for a Gallbladder Polyp.

Heterotopia or ectopic tissue refers to the presence of normal tissue in an abnormal location, away from its typical anatomic site. While heterotopia is not uncommon, its occurrence in the gallbladder is quite rare, and even more unusual is the presence of gastric heterotopia within the gallbladder. This case report describes a 41-year-old female patient with oxyntic-type heterotopic gastric mucosa in the proximal body of the gallbladder.

Crosstalk in Skin: Loss of Desmoglein 1 in Keratinocytes Inhibits BRAF-Induced Cellular Senescence in Human Melanocytes.

Melanoma arises from transformation of melanocytes in the basal layer of epidermis where they are surrounded by keratinocytes, with which they interact through cell contact and paracrine communication. Although research focuses on how the accumulation of oncogene and tumor suppressor gene mutations in melanocytes drive melanomagenesis, how alterations in keratinocytes serve as extrinsic drivers of melanoma initiation and progression is poorly understood. We recently identified keratinocyte desmoglein 1 (DSG1) as an mediator of keratinocyte:melanoma crosstalk.

Spatial and single-nucleus transcriptomic analysis of genetic and sporadic forms of Alzheimer's disease.

The pathogenesis of Alzheimer's disease (AD) depends on environmental and heritable factors, with its molecular etiology still unclear. Here we present a spatial transcriptomic (ST) and single-nucleus transcriptomic survey of late-onset sporadic AD and AD in Down syndrome (DSAD). Studying DSAD provides an opportunity to enhance our understanding of the AD transcriptome, potentially bridging the gap between genetic mouse models and sporadic AD.

Meningeal Dissemination and Drop Metastasis From Glioma Presenting With Non-Epileptic Myoclonus and Minipolymyoclonus.

We describe the case of a 36-year-old woman with a past medical history of low grade right frontal lobe glioma and focal epilepsy presenting with subacute, progressive, multifocal myoclonus and neck and back pain. Unlike her typical seizures, the myoclonus exhibited a distinct semiology, involving both positive and negative muscle jerks affecting multiple limb muscles while sparing the face. In addition, neurological examination revealed low-amplitude, arrhythmic movements of the hands and fingers, resembling minipolymyoclonus.

Methods: This prospective case series examines clinical data from five patients who underwent airway reconstruction surgeries and one patient who underwent total laryngectomy at Ayder Comprehensive Specialized Hospital in Mekelle. Data included patient demographics, airway stenosis etiology and severity, operative details, postoperative outcomes, complications, and hospital length of stay.

From one death to another: The relationship between familial deaths and one's own mortality risk among an urban Black American cohort.

Black Americans continue to be 1.5 times more likely to experience premature death with life expectancy up to six years shorter than their white American counterparts. These racial disparities in mortality translate into Black Americans being much more likely to experience the deaths of family members at younger ages in the life course.

Outputs from a model of co-research with older care-experienced people in Sweden to advance eldercare services.

Background: Within the contemporary policy turn towards co-production and co-research in Sweden, older people, practitioners and researchers alike have expressed uncertainty about how to undertake co-research. Moreover, scepticism persists about the merits and contributions of co-research and co-production to research and service development. In this paper, we aim to describe a co-research model developed with older care-experienced lay co-researchers and explore the utility of our model's outcomes to social care research and practice.

A Programming Algorithm for Optimizing Hypoglossal Nerve Stimulator Respiratory Entrainment.

Hypoglossal nerve stimulation (HNS) is a surgical treatment for obstructive sleep apnea that activates in a phasic manner. The most widely available HNS device has respiratory entrainment programming settings that are not widely utilized. We present an algorithm for office-based respiratory sensing adjustments to optimize HNS respiratory entrainment.

Exaptation of an evolutionary constraint enables behavioural control over the composition of secreted venom in a giant centipede.

Venoms are biochemical arsenals that have emerged in numerous animal lineages, where they have co-evolved with morphological and behavioural traits for venom production and delivery. In centipedes, venom evolution is thought to be constrained by the morphological complexity of their venom glands due to physiological limitations on the number of toxins produced by their secretory cells. Here we show that the uneven toxin expression that results from these limitations have enabled Scolopendra morsitans to regulate the composition of their secreted venom despite the lack of gross morphologically complex venom glands.

Myeloid-derived β-hexosaminidase is essential for neuronal health and lysosome function: implications for Sandhoff disease.

Lysosomal storage disorders (LSDs) are a large disease class involving lysosomal dysfunction, often resulting in neurodegeneration. Sandhoff disease (SD) is an LSD caused by a deficiency in the β subunit of the β-hexosaminidase enzyme (). Although expression in the brain is specific to microglia, SD primarily affects neurons.

Single-cell transcriptional analysis of murine norovirus infection in a human intestinal cell line.

Noroviruses are a major agent of acute gastroenteritis in humans, but host cell requirements for efficient replication have not been established. We engineered a human intestinal cell line (designated mCD300lf-hCaco2) expressing the murine norovirus (MNV) receptor, mouse CD300lf to become fully permissive for MNV replication. To explore the replicative machinery and host response of these cells, we performed a single-cell RNA sequencing (scRNA-seq) transcriptomics analysis of an MNV infection over time.
