SARS-CoV-2 vaccine responses that could harbor potential risks to chronic liver diseased patients. Aims: To assess immune response following Pfizer's SARS-CoV-2 vaccine in patients with different liver fibrosis severities of nonalcoholic fatty liver disease (NAFLD).

Epidermolysis bullosa (EB) features skin and mucosal fragility due to pathogenic variants in genes encoding components of the cutaneous basement membrane. Based on the level of separation within the dermal-epidermal junction, EB is sub-classified into four major types including EB simplex (EBS), junctional EB (JEB), dystrophic EB (DEB), and Kindler EB (KEB) with 16 EB-associated genes reported to date. We ascertained a cohort of 151 EB patients of various Middle Eastern ethnic backgrounds.

With the collapse of the medical system in Syria, Israel began providing Syrians with humanitarian aid, first to the war-injured and then general medical treatment. We developed a novel specialist ambulatory care concept to provide medical care for Syrian children.

Takotsubo syndrome (TTS) is a form of reversible cardiomyopathy often preceded by mental or physical stressors and predominantly affects elderly women. Several cardiac and inflammatory biomarkers are involved in the pathogenesis of the disease. We aimed to investigate the correlation of C-reactive protein (CRP) level with left ventricular ejection fraction (LVEF) and clinical outcomes in patients with TTS.

There is an ongoing debate on the indications for tonsil surgery in both children and adults with recurrent acute tonsillitis. The aim is to provide practical recommendations for diagnostics and treatment for recurrent acute tonsillitis including evidence-based decision making for tonsillectomy.

Some mothers may seek lactation inhibition on personal, social, or medical grounds. The common drug used for lactation inhibition is cabergoline. Several adverse effects and contraindications are known for this drug. Its use is contraindicated for patients with hypertensive disorders and fibrotic, cardiac, or hepatic diseases. Pyridoxine (Vitamin B6) has also been used for this indication, with no significant adverse effects, following studies that demonstrated its efficacy.

Technological advancement may bridge gaps between long-practiced medical competencies and modern technologies. Such a domain is the application of digital stethoscopes used for physical examination in telemedicine. This study aimed to validate the level of consensus among physicians regarding the interpretation of remote, digital auscultation of heart and lung sounds.

Venoarterial extracorporeal membrane oxygenation (VA-ECMO) use for circulatory support in cardiogenic shock results in increased left ventricular (LV) afterload. The use of concomitant Impella or intra-aortic balloon pump (IABP) have been proposed as adjunct devices for LV unloading. The authors sought to compare head-to-head efficacy and safety outcomes between the 2 LV unloading strategies. 

Objective: To determine the overall surgical outcomes of infranotch T4b oral cancers and compare them with T4a oral cancers.

Laparoscopic surgery in patients with obesity with situs inversus (SI) may pose interesting challenges to diagnosing and managing due to the mirror image anatomy. Since in SI patient's organs are displaced, the surgery requires high levels of precision and hand-eye coordination. SI and bariatric surgery may pose challenges for the surgical team.

Maxillomandibular advancement (MMA) remains an effective procedure for the management of obstructive sleep apnea (OSA). Maxillary advancement may lead to anatomical changes that impair paranasal sinus drainage, leading to chronic sinus inflammation. The aim of this study was to describe the clinical features and outcomes of patients suffering from chronic rhinosinusitis (CRS) following MMA.

We previously reported that autologous-fecal-microbiota-transplantation (aFMT), following 6 m of lifestyle intervention, attenuated subsequent weight regain and insulin rebound for participants consuming a high-polyphenol green-Mediterranean diet. Here, we explored whether specific changes in the core (abundant) vs. non-core (low-abundance) gut microbiome taxa fractions during the weight-loss phase (0-6 m) were differentially associated with weight maintenance following aFMT.

 Investigates the effect of ptosis surgery on dry eye disease as measured by dry eye parameters and meibomian gland function.

Autism is a neurodevelopmental disorder characterized by early-onset social behavioral deficits and repetitive behaviors. Chromodomain helicase DNA-binding protein (CHD8) is among the genes most strongly associated with autism. In addition to the core behavioral symptoms of autism, affected individuals frequently present with gastrointestinal symptoms that are also common among individuals harboring mutations in the gene encoding CHD8. However, little is known regarding the mechanisms whereby CHD8 affects gut function. In addition, it remains unknown whether gastrointestinal manifestations contribute to the behavioral phenotypes of autism. The current study found that mice haploinsufficient for the large isoform of Chd8 (Chd8L) exhibited increased intestinal permeability, transcriptomic dysregulation in gut epithelial cells, reduced tuft cell and goblet cell counts in the gut, and an overall increase in microbial load.
