Real-life nationwide characteristics and outcomes of small cell lung cancer over the last 20 years: Impact of immunotherapy on overall survival in a real-life setting.

Background: The KBP studies are real-life nationwide, prospective, multicenter cohort studies of patients diagnosed with primary lung cancer that have been conducted in French non-academic public hospitals each decade since 2000.

Methods: Patients were analyzed in three prospective cohorts using the same methodology. In this study, we describe and compare the characteristics and outcomes of patients with small cell lung cancer (SCLC), with a focus on treatments in the 2020 cohort.

Microvascular injuries, secondary edema, and inconsistencies in lung vascularization between affected and nonaffected pulmonary segments of non-critically ill hospitalized COVID-19 patients presenting with clinical deterioration.

Purpose: We aimed to better understand the pathophysiology of SARS-CoV-2 pneumonia in non-critically ill hospitalized patients secondarily presenting with clinical deterioration and increase in oxygen requirement without any identified worsening factors.

Methods: We consecutively enrolled patients without clinical or biological evidence for superinfection, without left ventricular dysfunction and for whom a pulmonary embolism was discarded by computed tomography (CT) pulmonary angiography. We investigated lung ventilation and perfusion (LVP) by LVP scintigraphy, and, 24 h later, left and right ventricular function by Tc-99m-labeled albumin-gated blood-pool scintigraphy with late (60 mn) tomographic albumin images on the lungs to evaluate lung albumin retention that could indicate microvascular injuries with secondary edema.

Descriptive study of a method for identification of the pylorus by ultrasound in lactating Holstein cows.

The purpose of this study was to develop a method for identification of the pylorus, in lactating Holstein cows, based on ultrasound examination and the use of external anatomical landmarks such as the mammary vein . An ultrasound method based on successive identification of 4 internal anatomical landmarks was developed. The procedure was performed 157 times, on clinically healthy lactating Holstein cows, with a portable ultrasound machine equipped with a 3.

[Impact of AMARA VIEW™ interface on upper airway during nocturnal non invasive ventilation].

Introduction: Nasal masks can result in mouth leaks with implications on sleep quality. To reduce these leaks, oronasal masks are proposed. It has been shown that an oronasal mask can induce obstructive events in the upper airways (UA).
