Tumor necrosis factor-stimulated gene-6 inhibits endoplasmic reticulum stress in the ischemic mouse kidney.

Kidney tissue injury in renal artery stenosis (RAS) involves inflammation, endoplasmic reticulum stress (ERS), and mitochondria damage. Tumor necrosis factor-stimulated gene-6 (TSG-6), an endogenous reparative molecule, may decrease ERS and improve renal function. To assess its impact on the stenotic murine kidney, we injected TSG-6 or vehicle for two weeks in mice with RAS.

toxicological evaluation of pouched portioned oral nicotine products.

Introduction: Modern oral nicotine pouch products (ONPs) are a category of oral nicotine products which contain pharmaceutical-grade nicotine, flavors, and other food-grade ingredients but no tobacco leaf. Recent reports indicate that ONPs in general do not contain (or only at minimal levels) the harmful and potentially harmful constituents (HPHCs) identified in cigarette smoke, suggesting their potential as alternative products for reducing harm from cigarette smoking.

Methods: We assessed toxicological effects of eight ONPs, designated as modern oral (MO) 1 to 8 along with an ONP, an oral tobacco (snus), and a combustible cigarette market comparator using established regulatory toxicological assays including Ames, micronucleus (ivMN), and neutral red uptake (NRU) assays.

Gabapentinoid use and the risk of fractures in patients with inflammatory arthritis: nested case-control study in the Clinical Practice Research Datalink Aurum.

Background: Gabapentinoids are increasingly prescribed in inflammatory arthritis (IA), despite no trial evidence for efficacy at managing pain in this population. Observational studies in non-IA populations suggest gabapentinoids are associated with fractures but are limited by methodological heterogeneity/potential residual confounding. Patients with IA generally have an increased risk of fracture so may be particularly vulnerable.

Reducing the Risk: An Evidence-Based Approach to the Febrile Infant <60 Days of Age in the Emergency Department.

Fever is the most common complaint for children of all ages who present to an emergency department (ED) for evaluation and treatment. Although most children with fever have a self-limiting viral illness, the infant less than 60 days of age with fever poses a higher risk for an underlying serious bacterial illness (SBI) including urinary tract infections, bacteremia and bacterial meningitis, or an invasive bacterial infection (IBI) including bacteremia. This case is a discussion of a high-risk febrile infant that was evaluated in the emergency department and was ultimately diagnosed with Streptococcus B meningitis.
