Perspectives and practices of dietitians with regards to social/mass media use during the transitions from face-to-face to telenutrition in the time of COVID-19: A cross-sectional survey in 10 Arab countries.

During the COVID-19 pandemic, most healthcare professionals switched from face-to-face clinical encounters to telehealth. This study sought to investigate the dietitians' perceptions and practices toward the use of social/mass media platforms amid the transition from face-to-face to telenutrition in the time of COVID-19. This cross-sectional study involving a convenient sample of 2,542 dietitians (mean age = 31.

Design: Multicentre, retrospective observational study.

Setting: Four tertiary hospitals in Saudi Arabia.

The clinical and genetic Spectrum of Maroteaux-Lamy syndrome (Mucopolysaccharidosis VI) in the Eastern Province of Saudi Arabia.

Mucopolysaccharidosis (MPS VI) or Maroteaux-Lamy syndrome is an autosomal recessive lysosomal storage disease caused by deficiency of the enzyme N-acetylgalactosamine 4-sulfatase or arylsulfatase B. It is involved in the degradation of glycosaminoglycans and characterized by a wide spectrum of clinical and genetic heterogeneity. So far, more than 150 mutations have been reported in the ARSB gene.

Six-min walk test in a healthy adult Arab population.

Background: The 6-min walk test (6MWT) is a submaximal exercise test used to assess functional status in patients with cardiopulmonary diseases. Regression equations have previously been published as a normal reference for 6-min walk distance (6MWD) in healthy Caucasian adults. However, a recent study showed that the normal predicted 6MWD could differ among ethnic populations.

Effect of lung compliance and endotracheal tube leakage on measurement of tidal volume.

Introduction: The objective of this laboratory study was to measure the effect of decreased lung compliance and endotracheal tube (ETT) leakage on measured exhaled tidal volume at the airway and at the ventilator, in a research study with a test lung.

Methods: The subjects were infant, adult and pediatric test lungs. In the test lung model, lung compliances were set to normal and to levels seen in acute respiratory distress syndrome.
