Sensory disabilities have been identified as significant risk factors for dementia but underlying molecular mechanisms are unknown. In different Drosophila models with loss of sensory input, we observe non-autonomous induction of the integrated stress response (ISR) deep in the brain, as indicated by eIF2α phosphorylation-dependent elevated levels of the ISR effectors ATF4 and XRP1. Unlike during canonical ISR, however, the ATF4 and XRP1 transcription factors are enriched in cytosolic granules that are positive for RNA and the stress granule markers Caprin, FMR1, and p62, and are reversible upon restoration of vision for blind flies.

Introduction The utilization of physician associates (PAs) and nurse practitioners (NPs) within the United States healthcare system has increased substantially since their inception in the 1960s. While many PAs and NPs are educated and work within specialty areas in their clinical practice, the federal government does not identify PAs and NPs by specialty in its workforce projections. Methods We obtained data from publicly available sources as well as professional organizations.

To address the limitations in existing urinary stone recurrence (USR) models, including failure to account for changes in 24-hour urine (24U) parameters over time and ignoring multiplicity of stone recurrences, we presented a novel statistical method to jointly model temporal trends in 24U parameters and multiple recurrent stone events. The MSTONE database spanning May 2001 to April 2015 was analyzed. A joint recurrent model was employed, combining a linear mixed-effects model for longitudinal 24U parameters and a recurrent event model with a dynamic first-order Autoregressive (AR(1)) structure.

Fungal pathogens within the urine, specifically Candida species, are a common finding amongst hospitalized patients. Risk factors for the development of candiduria involve patients with indwelling urinary drainage devices, surgical patients, patients undergoing urologic instrumentation, and diabetic patients. Candiduria often presents with an asymptomatic course but can also be a severe life-threatening process.

Pain and inflammation contribute immeasurably to reduced quality of life, yet modern analgesic and anti-inflammatory therapeutics can cause dependence and side effects. Here, we screened 1444 plant extracts, prepared primarily from native species in California and the United States Virgin Islands, against two voltage-gated K channels - T-cell expressed Kv1.3 and nociceptive-neuron expressed Kv7.

Human studies of early brain development have been limited by extant neuroimaging methods. MRI scanners present logistical challenges for imaging young children, while alternative modalities like functional near-infrared spectroscopy have traditionally been limited by image quality due to sparse sampling. In addition, conventional tasks for brain mapping elicit low task engagement, high head motion, and considerable participant attrition in pediatric populations.

Sea surface temperatures are rising at unprecedented rates, leading to a progressive degradation of complex habitats formed by coral reefs. In parallel, acute thermal stress can lead to physiological challenges for ectotherms that inhabit coral reefs, including fishes. Warming and habitat simplification could push marine fishes beyond their physiological limits in the near future.

Objective: To assess the extent of formal point-of-care ultrasound (POCUS) training, current utilization of POCUS, and contemporary perceptions of POCUS amongst urologists.

Methods: A survey including questions regarding demographics, prior ultrasound education, current ultrasound utilization in practice/training, perceived optimal POCUS utilization, and the perception of formal ultrasound training was developed. The survey was disseminated to residency program directors (PDs) via the SAU and members of AUA subsection organizations.

Background: Robotic retroperitoneal partial nephrectomy (rRPN) has numerous advantages over transperitoneal surgery, including direct access to the renal hilum and posterior tumors, and avoidance of the peritoneal cavity in patients with a hostile abdomen. Although the use of the retroperitoneal approach has increased over the last decade, there is little literature on robotic retroperitoneal radical nephrectomy (rRRN), which has similar benefits over the transperitoneal approach. The aim of this study was to describe our technique for robotic retroperitoneal nephrectomy (rRN) and assess its feasibility and outcomes at a high-volume center.

Background: Bladder recurrence after radical nephroureterectomy (RNU) is common and randomized data supports utilization of prophylactic intravesical mitomycin to reduce recurrence. Recently, gemcitabine has been shown to be safe and effective at reducing recurrence following transurethral resection of bladder tumors. We sought to evaluate the safety and efficacy of a single, intraoperative gemcitabine instillation immediately following bladder cuff closure during RNU, and to compare outcomes with non-gemcitabine intravesical chemotherapy agents.

Background: Although there is a substantial body of evidence regarding full practice authority's (FPA) effects on health care access and quality, very little research has examined how nurse practitioner (NP) licensure laws affect the status of NPs as clinicians, employees, and leaders in health care organizations.

Purpose: This study examined whether states' implementation of FPA leads to higher pay, business ownership, assigned patient panel, and billing transparency for NPs' and whether NPs' gains from FPA increase over time in states where FPA has been in effect longer.

Methodology: Data from a nationwide survey of licensed NPs ( N = 5,770) were used to compare NPs' employment conditions between FPA and non-FPA states.

T3a renal masses include a diverse group of tumors that invade the perirenal and/or sinus fat, pelvicaliceal system, or renal vein. The majority of cT3a renal masses represent renal cell carcinoma (RCC) and have historically been treated with radical nephrectomy (RN) given their aggressive nature. With the adoption of minimally invasive approaches to renal surgery, the combination of improved observation, pneumoperitoneum, and robotic articulation has allowed urologists to consider partial nephrectomy (PN) for more complex tumors.

Cardiac physiologic pacing (CPP), encompassing cardiac resynchronization therapy (CRT) and conduction system pacing (CSP), has emerged as a pacing therapy strategy that may mitigate or prevent the development of heart failure (HF) in patients with ventricular dyssynchrony or pacing-induced cardiomyopathy. This clinical practice guideline is intended to provide guidance on indications for CRT for HF therapy and CPP in patients with pacemaker indications or HF, patient selection, pre-procedure evaluation and preparation, implant procedure management, follow-up evaluation and optimization of CPP response, and use in pediatric populations. Gaps in knowledge, pointing to new directions for future research, are also identified.
