Evaluation of Left Diastolic Function in Dilated Cardiomyopathy According to the 2016 ASE/EACVI Recommendations.

Objectives: To assess left ventricular diastolic function by using echocardiography in patients with dilated cardiomyopathy, and the relationship between left ventricular diastolic function and left ventricular dilatation, New York Heart Association (NYHA) heart failure index, left ventricular ejection fraction, and left ventricular fractional shortening.

Methods: A descriptive cross-sectional study was conducted on patients with primary dilated cardiomyopathy hospitalized in Hue Central Hospital from April 2018 to August 2020.

Results: The mean end-diastolic left ventricular volume was 133.

Impact on the Gut Microbiota of Intensive and Prolonged Antimicrobial Therapy in Patients With Bone and Joint Infection.

There is a growing interest in the potentially deleterious impact of antibiotics on gut microbiota. Patients with bone and joint infection (BJI) require prolonged treatment that may impact significantly the gut microbiota. We collected samples from patients with BJI at baseline, end of antibiotics (EOT), and 2 weeks after antibiotic withdrawal (follow-up, FU) in a multicenter prospective cohort in France.

Online self-sampling kits to screen multipartner MSM for HIV and other STIs: participant characteristics and factors associated with kit use in the first 3 months of the MemoDepistages programme, France, 2018.

Objectives: In 2017, to reduce the proportion of men who have sex with men (MSM) in the undiagnosed HIV population in France (38%), HIV screening is advised each 3 months and STI screening is advised each year in multipartner MSM. Despite the range of testing solutions, over 40% of MSM were not tested for HIV and over 50% for STIs in the past year. Based on international experiments that offer screening solutions via online advertising, the French National Health Agency launched a programme (MemoDepistages) to provide a free self-sampling kit (SSK) for HIV and STIs.

TGF-β1-driven reduction of cytoglobin leads to oxidative DNA damage in stellate cells during non-alcoholic steatohepatitis.

Background & Aims: Cytoglobin (CYGB) is a respiratory protein that acts as a scavenger of reactive oxygen species. The molecular role of CYGB in human hepatic stellate cell (HSC) activation and human liver disease remains uncharacterised. The aim of this study was to reveal the mechanism by which the TGF-β1/SMAD2 pathway regulates the human CYGB promoter and the pathophysiological function of CYGB in human non-alcoholic steatohepatitis (NASH).

The Hemoglobin Homolog Cytoglobin in Smooth Muscle Inhibits Apoptosis and Regulates Vascular Remodeling.

Objective: The role of hemoglobin and myoglobin in the cardiovascular system is well established, yet other globins in this context are poorly characterized. Here, we examined the expression and function of cytoglobin (CYGB) during vascular injury.

Approach And Results: We characterized CYGB content in intact vessels and primary vascular smooth muscle (VSM) cells and used 2 different vascular injury models to examine the functional significance of CYGB in vivo.
