Multidimensional phenotyping to distinguish among distinct obstructive sleep apnea, chronic obstructive pulmonary disease, and overlap syndrome phenotypes.

Objective/background: Chronic obstructive pulmonary disease (COPD), obstructive sleep apnea (OSA) and their comorbid association called Overlap Syndrome (OS) are frequent chronic diseases with high individual and societal burdens. Precise descriptions of the respective symptoms, comorbidities, and medications associated with these three conditions are lacking. We used a multidimensional phenotyping approach to identify relevant phenotypes characterizing these 3 disorders.

Early Prone versus Supine Positioning in Moderate to Severe Coronavirus Disease 2019 Patients with Acute Respiratory Distress Syndrome.

Objectives: This study sought to determine whether early prone positioning of patients with moderate to severe COVID-19-related acute respiratory distress syndrome (ARDS) lowers the mortality rate.

Methods: We conducted a retrospective study using data from intensive care units of two tertiary centers in Oman. Adult patients with moderate to severe COVID-19-related ARDS with a PaO2/FiO2 ratio < 150 on FiO2 of 60% or more and a positive end-expiratory pressure of at least 8 cm H2O who were admitted between 1 May 2020 and 31 October 2020 were selected as participants.

Detection of condition-specific marker genes from RNA-seq data with MGFR.

The identification of condition-specific genes is key to advancing our understanding of cell fate decisions and disease development. Differential gene expression analysis (DGEA) has been the standard tool for this task. However, the amount of samples that modern transcriptomic technologies allow us to study, makes DGEA a daunting task.

Personalized medicine, pharmacogenomic and companion biomarker.

The aim of this review is to provide a brief overview of personalized medicine, pharmacogenetics and companion tests. Personalized or stratified medicine is a new paradigm in the management of patients, aimed at better taking into account inter-individual variability. The response to drugs' intake varies considerably, depending on the transport and metabolism of the drugs, the target and the pathophysiological characteristics of the organism.

Do Energy Drink Consumers Study More?

The use and motivations for use of energy drinks (EDs) in college students has been documented in the literature. Many college students identify academic reasons, such as a need to study more, as a motivation for ED use. However, research has not determined if users who claim academic motivations actually study more than those who claim other motivations.
