Impact of Gender and Marital Status on Door-to-Treatment (DTT) Time and Acute Stroke Outcome.

Objectives: Delays in acute stroke treatment lead to poor outcomes. Women can present with atypical stroke symptoms, are older at the time of stroke, and tend to be living alone, causing delays in pre-hospital diagnosis and seeking care. It is unclear if gender disparities in ED arrival and stroke assessment are compounded by gender differences after ED arrival.

Riociguat in patients with sickle cell disease and hypertension or proteinuria (STERIO-SCD): a randomised, double-blind, placebo controlled, phase 1-2 trial.

Background: Although nitric oxide based therapeutics have been shown in preclinical models to reduce vaso-occlusive events and improve cardiovascular function, a clinical trial of a phosphodiesterase 5 inhibitor increased rates of admission to hospital for pain. We aimed to examine if riociguat, a direct stimulator of the nitric oxide receptor soluble guanylate cyclase, causes similar increases in vaso-occlusive events.

Methods: This was a phase 1-2, randomised, double blind, placebo-controlled trial.

Radioligand therapy (RLT) used to treat cardiac metastasis of pancreatic neuroendocrine tumor.

Radioligand Therapy (RLT) in the form of [177Lu] Lu-DOTA-TATE (Lutathera®) is a promising treatment for pancreatic neuroendocrine tumors (pNETs) with cardiac metastasis. We present a patient treated with [177Lu] Lu-DOTA-TATE that showed shrinkage of metastasis after four treatments at 7.4 GBq every 8 weeks.

A multi-cohort genome-wide association study in African ancestry individuals reveals risk loci for primary open-angle glaucoma.

Primary open-angle glaucoma (POAG), the leading cause of irreversible blindness worldwide, disproportionately affects individuals of African ancestry. We conducted a genome-wide association study (GWAS) for POAG in 11,275 individuals of African ancestry (6,003 cases; 5,272 controls). We detected 46 risk loci associated with POAG at genome-wide significance.

Beyond Human Limits: Harnessing Artificial Intelligence to Optimize Immunosuppression in Kidney Transplantation.

The field of kidney transplantation is being revolutionized by the integration of artificial intelligence (AI) and machine learning (ML) techniques. AI equips machines with human-like cognitive abilities, while ML enables computers to learn from data. Challenges in transplantation, such as organ allocation and prediction of allograft function or rejection, can be addressed through AI-powered algorithms.

Radiation-induced myofibroblastoma within the nasal sinus requiring maxillectomy and ethmoidectomy: A case report and literature review.

We report a case of radiation-induced myofibroblastoma of the right nasal cavity in a patient with a remote history of radiotherapy for pediatric retinoblastoma. The patient required maxillectomy and ethmoidectomy. To our knowledge, a rare number of cases have been reported in this location.

Efzofitimod for the Treatment of Pulmonary Sarcoidosis.

Background: Pulmonary sarcoidosis is characterized by the accumulation of immune cells that form granulomas affecting the lungs. Efzofitimod (ATYR1923), a novel immunomodulator, selectively binds neuropilin 2, which is upregulated on immune cells in response to lung inflammation.

Research Question: What is the tolerability, safety, and effect on outcomes of efzofitimod in pulmonary sarcoidosis?

Study Design And Methods: In this randomized, double-blind, placebo-controlled study evaluating multiple ascending doses of efzofitimod administered intravenously every 4 weeks for 24 weeks, randomized patients (2:1) underwent a steroid taper to 5 mg/d by week 8 or < 5 mg/d after week 16.

COVID-19 Infection Enhances Susceptibility to Oxidative Stress-Induced Parkinsonism.

Background: Viral induction of neurological syndromes has been a concern since parkinsonian-like features were observed in patients diagnosed with encephalitis lethargica subsequent to the 1918 influenza pandemic. Given the similarities in the systemic responses after severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection with those observed after pandemic influenza, there is a question whether a similar syndrome of postencephalic parkinsonism could follow coronavirus disease 2019 infection.

Objective: The goal of this study was to determine whether prior infection with SARS-CoV-2 increased sensitivity to a mitochondrial toxin known to induce parkinsonism.

Seasonal Variation in the Diagnosis of Skin Cancers From 1983 to 2017 in Greenville, North Carolina.

Background Seasonality of diagnosis occurs in many types of cancer and is well-established in non-melanoma (NMSC) and melanoma (MSC) skin cancers. Benign skin conditions have also been shown to demonstrate a similar seasonality pattern. Investigations into the seasonality of NMSC and MSC diagnoses are less common than benign skin conditions despite the high healthcare burden of the disease.

TIGAR deficiency enhances skeletal muscle thermogenesis by increasing neuromuscular junction cholinergic signaling.

Cholinergic and sympathetic counter-regulatory networks control numerous physiological functions, including learning/memory/cognition, stress responsiveness, blood pressure, heart rate, and energy balance. As neurons primarily utilize glucose as their primary metabolic energy source, we generated mice with increased glycolysis in cholinergic neurons by specific deletion of the fructose-2,6-phosphatase protein TIGAR. Steady-state and stable isotope flux analyses demonstrated increased rates of glycolysis, acetyl-CoA production, acetylcholine levels, and density of neuromuscular synaptic junction clusters with enhanced acetylcholine release.

Temporal Changes in Mortality After Transcatheter and Surgical Aortic Valve Replacement: Retrospective Analysis of US Medicare Patients (2012-2019).

Background The treatment of aortic stenosis is evolving rapidly. Pace of change in the care of patients undergoing transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) differs. We sought to determine differences in temporal changes in 30-day mortality, 30-day readmission, and length of stay after TAVR and SAVR.

The potential effect of metabolic alkalosis on insulin sensitivity in an adolescent with new-onset type 1 diabetes.

Metabolic alkalosis induced by ingestion of alkaline water may enhance insulin sensitivity in type 1 diabetes mellitus.

A Case Study and Review of Literature of Eruptive Syringoma in a Six-Year-Old.

Syringomas are benign tumors originating from the intraepidermal portion of eccrine sweat ducts. A six-year-old African American female presented with multiple 2-3 mm hyperpigmented papules over the neck, upper chest, and axillae bilaterally. The lesions were non-tender, non-pruritic, and did not bleed when lightly scraped.

A case of the world's largest renal cell carcinoma.

Introduction: Renal cell carcinoma is often discovered at an early stage due to the increased use of imaging studies in the current era; therefore, its presentation as a gigantic renal cell carcinoma is rarely encountered.

Case Presentation: A 59-year-old male presented to our hospital due to dizziness, fatigue, and increasing abdominal distension. A computed tomography scan showed an extremely large mass occupying most of the abdomen and pelvis.

Tapping Out: Influence of Organoleptic and Perceived Health Risks on Bottled Versus Municipal Tap Water Consumption Among Obese, Low Socioeconomic Status Pediatric Patients.

A variety of endocrine disrupting chemicals (EDCs), including some known to be obesogenic, can be found in household wastewater. Many are only partially treated by wastewater treatment and drinking water purification systems and can enter municipal drinking water supplies. We evaluated drinking water consumption habits in a cohort of obese pediatric patients to determine the percentage that might avoid exposure to EDCs from drinking municipal tap water.

Matrix Metalloproteinase-12 Is Required for Granuloma Progression.

Background: Sarcoidosis is a chronic inflammatory disease of unknown cause characterized by granuloma formation. Mechanisms for chronic persistence of granulomas are unknown. Matrix Metalloproteinase-12 (MMP12) degrades extracellular matrix elastin and enables infiltration of immune cells responsible for inflammation and granuloma formation.

Impaired mitochondrial function of alveolar macrophages in carbon nanotube-induced chronic pulmonary granulomatous disease.

Human exposure to carbon nanotubes (CNT) has been associated with the development of pulmonary sarcoid-like granulomatous disease. Our previous studies demonstrated that multi-walled carbon nanotubes (MWCNT) induced chronic pulmonary granulomatous inflammation in mice. Granuloma formation was accompanied by decreased peroxisome proliferator-activated receptor gamma (PPARγ) and disrupted intracellular lipid homeostasis in alveolar macrophages.

Perioperative aspiration events in children: A report from the Wake Up Safe Collaborative.

Background: Perioperative aspiration, while rare, is a serious complication of anesthetic care. Consequences of aspiration may include physical obstruction, wheezing, and pneumonia, resulting in mild to severe hypoxemia and even death.

Aim: We used a multi-institutional registry of pediatric patients to identify factors that influence the rate and resulting harm of perioperative pulmonary aspiration.

Polymorphisms in () are Linked to Infection and Osteoporosis in Rheumatoid Arthritis.

We previously discovered that single nucleotide polymorphisms (SNPs) in (T-cell negative-regulators) occur in 78% of rheumatoid arthritis (RA), along with (MAP) infection in 33% of patients. In Crohn's disease, we reported that SNPs in and receptors () benefited intracellular MAP-survival, increased infection, and elevated inflammatory response mimicking the poor response to anti-TNF treatment in some patients. Here, we studied the frequency and effects of SNPs in in RA including gene expression, MAP infection, and osteoporosis marker levels in blood (54 RA and 48 healthy controls).

Occurrence of severe hypoglycaemic events among US youth and young adults with type 1 or type 2 diabetes.

Objective: Although severe hypoglycaemia (SH) can lead to adverse health outcomes, little is known about its occurrence and re-occurrence among youth with type 1 or type 2 diabetes.

Methods: This study included 2740 participants aged <20 years at diabetes diagnosis and 5-14 years diabetes duration from the SEARCH for Diabetes in Youth Cohort Study. Participants reported SH events in the past 6 months.
