In Obesity, Esophagogastric Junction Fat Impairs Esophageal Barrier Function and Dilates Intercellular Spaces via HIF-2α.

Background & Aims: Dilated intercellular space (DIS) in esophageal epithelium, a sign of impaired barrier function, is a characteristic finding of GERD that also is found in obese patients without GERD. We have explored molecular mechanisms whereby adipose tissue products might impair esophageal barrier integrity.

Methods: We established cultures of visceral fat obtained during foregut surgery from obese and non-obese patients.

Impact of glucagon-Like peptide-1 agonists in optimizing abdominal wall Reconstruction patients.

Purpose: Pre-optimization of obese patients prior to abdominal wall reconstruction (AWR) is essential in mitigating their increased preoperative risks. Traditionally diet, exercising, bariatric surgery are the tools typically prescribed for weight loss. The advent of glucagon-like peptide-1 agonists (GLP-1A) which stimulate insulin secretion and inhibit gastric emptying have improved the weight loss armamentarium.

Magnetic sphincter augmentation vs subtotal gastrectomy with Roux-en-Y reconstruction for the treatment of postsleeve gastrectomy gastroesophageal reflux disease.

Background: Obesity affects more than one-third of Americans and can be treated with bariatric surgery, most commonly sleeve gastrectomy (SG). SG has been shown to increase the incidence of gastroesophageal reflux disease (GERD) in some patients, which can be refractory to medical management. Surgical options for post-SG GERD include magnetic sphincter augmentation (MSA) and subtotal gastrectomy with Roux-en-Y reconstruction (SGRY).

Awareness and Application of United States Food Allergy Prevention Guidelines Among Pediatricians and Other Clinicians.

Objective: To characterize the awareness of, adherence to, and barriers to the 2017 National Institute of Allergy and Infectious Diseases (NIAID) peanut allergy prevention guidelines among the pediatrics health care workforce.

Study Design: Pediatricians, family physicians, advanced practice providers (APPs), and dermatologists who provide care for infants were solicited for a population-based online survey, administered from June 6, 2022, through July 3, 2022. The survey collected information about NIAID guideline awareness, implementation, and barriers as well as concerns related to the guidelines.

The impact of food matrices on egg allergenicity.

Background: Although many studies show the impact of high and prolonged heating on allergenicity, scarce research exists that examined the impact of the food matrix effect. We presented a case that demonstrates the need for further investigation into this field.

Case: An 8-month-old breast-fed girl with a history of moderate eczema presented with concern for food allergy.
