Introduction: Radical gastrectomy is associated with significant functional complications. In appropriate patients may be amenable to less invasive resection aimed at preserving the vagal trunks. The aim of this systematic review and meta-analysis was to assess the functional consequences and oncological safety of vagal sparing gastrectomy (VSG) compared to conventional non-vagal sparing gastrectomy (CG).

Article Synopsis
  • Choline acetyltransferase (ChAT) helps make a chemical called acetylcholine that can reduce inflammation in the body, especially through the vagus nerve.
  • Scientists tested if ChAT in the blood changes during inflammation and if it can help control the release of chemicals that cause inflammation.
  • They found that ChAT levels in mice increased after inflammation and that giving ChAT could lower inflammation, suggesting it might be useful as a treatment for inflammatory diseases in humans.

Background: Acute pancreatitis is a common and serious inflammatory condition currently lacking disease modifying therapy. The cholinergic anti-inflammatory pathway (CAP) is a potent protective anti-inflammatory response activated by vagus nerve-dependent α7 nicotinic acetylcholine receptor (α7nAChR) signaling using splenic CD4 T cells as an intermediate. Activating the CAP ameliorates experimental acute pancreatitis.

Introduction: This study examines whether the use of inpatient Continuous Glucose Monitors provides improved glycemic control over finger-stick glucose monitoring post-transplant.

Methods: This is a single-site, prospective randomized controlled trial of 40 patients receiving conventional finger-stick glucose monitoring or continuous monitoring using the Medtronic Guardian Sensor 3 during the first 5 days post-transplant. Included patients were adult renal transplant recipients with a diagnosis of diabetes.

Aim: The aim of the current research was to assess the ability of different dental varnishes in averting enamel demineralization adjoining the orthodontic brackets.

Materials And Methods: Seventy-five premolars devoid of dental caries that were subjected to extraction for orthodontic purposes were employed in this research. The surface of enamel was etched with 37% phosphoric acid and subjected to primer application.

Aim: The purpose of the current study was to investigate the presence of the ponticulus posticus (PP) frequently encountered in lateral cephalograms.

Materials And Methods: About 500 patients of age 12-40 years were selected whose digital lateral cephalogram was recorded and traced to confirm the presence of the PP and categorize as: (A) Absent, as evidenced by lateral cephalograms. (B) Complete PP evidenced by the presence of circumferential bone bridge that connected the upper articular process to the atlas's posterior arch.

Aim: The present investigation aims to find out the prevalence of ectopic canines among skeletal class I, II, and III malocclusions and to evaluate its variability among different genders and their growth patterns.

Material And Methods: The study sample included orthopantomograms (OPGs), lateral skull views, and study models of 999 patients collected from departmental archives. Among the selected samples, 258 were males and 738 were females.

Background: Up to 60% of arteriovenous fistulas (AVF) require intervention to assist maturation, which prolongs the time until it can be used for hemodialysis (HD). Current guidelines recommend early postoperative AVF examination to detect and address immaturity to decrease time to maturation. This study evaluates how the timing of postoperative follow-up to assess AVF maturity affects patients' outcomes.

Background: Neuroinflammation is an important driver of acute and chronic pain states. Therefore, targeting molecular mediators of neuroinflammation may present an opportunity for developing novel pain therapies. In preclinical models of neuroinflammatory pain, calcitonin gene-related peptide (CGRP), substance P and high mobility group box 1 protein (HMGB1) are molecules synthesized and released by sensory neurons which activate inflammation and pain.

Background: Severe COVID-19 is characterized by pro-inflammatory cytokine release syndrome (cytokine storm) which causes high morbidity and mortality. Recent observational and clinical studies suggest famotidine, a histamine 2 receptor (H2R) antagonist widely used to treat gastroesophageal reflux disease, attenuates the clinical course of COVID-19. Because evidence is lacking for a direct antiviral activity of famotidine, a proposed mechanism of action is blocking the effects of histamine released by mast cells.

Article Synopsis
  • The study aimed to evaluate and compare frictional forces from passive self-ligating brackets versus two types of elastomeric ligatures (UELs and CELs) used with conventional brackets and different archwires.
  • Eight conventional stainless steel brackets and four passive SLBs were tested using a custom jig and a universal testing machine to measure friction.
  • The results indicated that UELs on conventional brackets and SLBs produced lower friction compared to CELs on conventional brackets, with SLBs showing slightly lower static but higher kinetic friction.

Inflammation, the body's primary defensive response system to injury and infection, is triggered by molecular signatures of microbes and tissue injury. These molecules also stimulate specialized sensory neurons, termed nociceptors. Activation of nociceptors mediates inflammation through antidromic release of neuropeptides into infected or injured tissue, producing neurogenic inflammation.
