Jejunal obstruction due to jejunocolic congenital band in a 12-year-old child: a case report.

Background: A congenital band is an uncommon abnormality that can be found anywhere along the gastrointestinal tract. Intestinal obstruction caused by an anomalous congenital band is very rare in children. To the best of our knowledge, no cases of congenital bands extending from the descending colon to the jejunum have been reported in the English literature CASE PRESENTATION: Herein, we present the case of a 12-year-old Syrian patient with intestinal obstruction due to a congenital band extending from the mesentery of the descending colon to the mesentery of the jejunum with an entrapped loop of jejunum between the band and the mesentery.

Severe vitamin D deficiency is not related to SARS-CoV-2 infection but may increase mortality risk in hospitalized adults: a retrospective case-control study in an Arab Gulf country.

Purpose: As the world continues to cautiously navigate its way through the coronavirus disease 2019 (COVID-19) pandemic, several breakthroughs in therapies and vaccines are currently being developed and scrutinized. Consequently, alternative therapies for severe acute respiratory coronavirus 2 (SARS-CoV-2) prevention, such as vitamin D supplementation, while hypothetically promising, require substantial evidence from countries affected by COVID-19. The present retrospective case-control study aims to identify differences in vitamin D status and clinical characteristics of hospitalized patients screened for SARS-CoV-2, and determine associations of vitamin D levels with increased COVID-19 risk and mortality.

Diabetes and Covid-19 among hospitalized patients in Saudi Arabia: a single-centre retrospective study.

Background: Information on the clinical characteristics and outcomes of hospitalized Covid-19 patients with or without diabetes mellitus (DM) is limited in the Arab region. This study aims to fill this gap.
