Hemodynamic profile of pulmonary arterial hypertension in a Tunisian center.

Introduction: Pulmonary hypertension (PH) management can only be conceived in a specialized center. We aimed to report the experience of a Tunisian ICU about PH invasive hemodynamic exploration and to describe consequent therapeutic decisions.

Methods: Retrospective descriptive study including all patients admitted to the medical ICU of Abderrahmen Mami Hospital for right heart catheterization (RHC), between 2005 and 2019 as part of the investigation of PH.

Comparison of the clinical features and outcomes of severe seasonal influenza and COVID-19 patients in Tunisia between 2021 and 2022.

Background: We compared patients diagnosed at a SARI (severe acute respiratory infections) surveillance site with COVID-19 and those with seasonal influenza to investigate the clinical differences, common features, and outcomes.

Methods: We conducted a descriptive, retrospective study in the Medical Intensive Care Unit (ICU) at Abderrahman Mami Hospital between September 2021 and April 2022. Demographic, clinical, and biological data as well as outcomes were recorded for all patients.

Interleukin6 prediction of mortality in critically ill COVID19 patients: A prospective observational cohort study.

Objective: The aim of this study is to explore the role of IL6 in predicting outcome in critically ill COVID-19 patients. Design Prospective observational cohort study. Setting 20-bed respiratory medical intensive care unit of Abderrahmen Mami Teaching Hospital between September and December 2020.

Sensitivity and resolution optimization in gas chromatography coupled to mass spectrometry analyses of volatile organic compounds present in vacuum environment.

The gaseous phase analyses of volatile organic compounds (VOCs) are an important challenge especially when these organics are formed in high vacuum environments (10 mbar) reproducing the environment of astrophysical ices formation and processing. Several analytical techniques have been developed to identify the molecular diversity formed from the processing of these ices. Among them, the coupling of a GC-MS to the vacuum chamber where ices are processed highlighted the interesting chemical diversity of such processed ices.
