Purpose: To evaluate the efficacy and safety of Ahmed glaucoma valve (AGV) implantation with subsequent trans-scleral diode cyclophotocoagulation (CPC) as the main intervention if IOP remained medically uncontrolled.
Patients And Methods: Charts of 108 consecutive eyes (90 patients) that underwent AGV implantation from 2003 to 2018 at a single clinical practice were retrospectively reviewed. The procedure was considered a failure if any of the following occurred: additional incisional glaucoma surgery, IOP >21 mmHg or < 20% reduction from baseline on 2 consecutive study visits after 3 months, IOP ≤ 5 mmHg on 2 consecutive study visits after 3 months, loss of light perception, or AGV removal.

As the SARS-CoV-2 coronavirus continues to evolve and infect the global population, many individuals are likely to suffer from post-acute sequelae of SARS-CoV-2 infection (PASC). Manifestations of PASC include vision symptoms, but little is known about the ability of SARS-CoV-2 to infect and impact the retinal cells. Here, we demonstrate that SARS-CoV-2 can infect and perturb the retinal pigment epithelium (RPE) in vivo, after intranasal inoculation of a transgenic mouse model of SARS-CoV-2 infection, and in cell culture.

Exposure to organophosphorus nerve agents irreversibly inhibits acetylcholinesterase and may lead to cholinergic crisis and seizures. Although benzodiazepines are the standard of care after nerve agent-induced status epilepticus, when treatment is delayed for up to 30 min or more, refractory status epilepticus can develop. Adult male rodents are often utilized for evaluation of therapeutic efficacy against nerve agent exposure.

Background: Intimate partner violence affects about a third of women in their lifetimes and can result in short- and long-term health consequences, including less favorable performance on measures of cognitive function.
Objectives: We assess whether experiencing physical intimate partner violence in midlife was associated with steeper declines in subsequent tests of cognitive performance.
Design: This study used data from 1713 women in the longitudinal cohort Study of Women's Health Across the Nation to relate baseline information on physical intimate partner violence to declines in scores from the Symbol Digit Modalities Test, the East Boston Memory Test and the Digit Span Backwards spanning follow-up visits 7 through 15.

Objectives: Evidence indicates that, in pediatric patients with parenteral nutrition-associated cholestasis (PNAC), the use of a 100% fish oil lipid emulsion (FOLE) increased the likelihood of PNAC resolution and reduced the likelihood of liver transplantation compared with a 100% soybean oil lipid emulsion (SOLE). To evaluate the potential economic benefit, we conducted a cost-effectiveness analysis comparing FOLE with SOLE.
Study Design: A discrete event simulation model evaluated cost-effectiveness by simulating clinical outcomes and estimating associated healthcare costs in pediatric patients with PNAC receiving parenteral nutrition (PN) with FOLE (1 g/kg) or SOLE (1.

Clinical trials of treatments for stroke have generally utilized 2-arm, randomized designs to evaluate a single intervention against a control. Running separate clinical trials, with each addressing a single therapeutic question, is resource intensive and slows evidence generation, especially in a field with rapidly expanding treatment options and evolving practices. Platform trials-randomized clinical trials designed to evaluate multiple interventions that may enter and exit the ongoing platform based on a master protocol-accelerate the investigation of multiple therapeutic options within a single infrastructure.

Small molecule Janus kinase (JAK) inhibitors have revolutionized the management of ulcerative colitis (UC) and Crohn's disease (CD) through their low immunogenicity, safety, and consistent pharmacologic response that are superior to existing therapeutic options. In this perspective, we highlight existing evidence supporting the use of currently approved JAK inhibitors (upadacitinib, tofacitinib, and filgotinib) for UC or CD, additionally emphasizing the evidence for their use in related autoimmune conditions such as rheumatoid arthritis and spondyloarthropathies. Our perspective concludes with a review of the existing comparative effectiveness literature, which positions JAK inhibitors, particularly upadacitinib, favorably compared with other biologic therapies.

Electroencephalography (EEG) captures characteristic oscillatory shifts in infant brain rhythms over the first year of life, offering unique insights into early functional brain development and potential markers for detecting neural differences associated with autism. This study used functional principal component analysis (FPCA) to derive dynamic markers of spectral maturation from task-free EEG recordings collected at 3, 6, 9, and 12 months from 87 infants, 51 of whom were at higher likelihood of developing autism due to an older sibling diagnosed with the condition. FPCA revealed three principal components explaining over 96% of the variance in infant power spectra, with power increases between 6 and 9 Hz (FPC1) representing the most significant age-related trend, accounting for more than 71% of the variance.
