The study consisted in comparison of the microecology and the parameters of the humoral immunity of the biotopes of the respiratory and urogenital tracts under normal conditions and in inflammatory processes caused by bacterial agents. The study revealed significant changes in the microbiocenosis of the respiratory and urogenital tracts, caused by decline of indigenous microflora and increase of the content of conditionally pathogenic microorganisms. These changes depended on the degree of the infectious process severity. Measurement of the humoral immunity parameters revealed a significant correlation between the content of conditionally pathogenic microorganisms and the levels of M and A immunoglobulins, as well as secretory IgA and free secretory component (sc) in the vaginal secretions of patients with non-specific inflammatory diseases of the genital tract, as well as G and A immunoglobulins, secretory IgA, and sc in the saliva of patients with chronic inflammatory diseases of the respiratory tract.

With over 14 million people living above 3,500 m, the study of acclimatization and adaptation to high altitude in human populations is of increasing importance, where exposure to high altitude (HA) imposes a blood oxygenation and acid-base challenge. A sustained and augmented hypoxic ventilatory response protects oxygenation through ventilatory acclimatization, but elicits hypocapnia and respiratory alkalosis. A subsequent renally mediated compensatory metabolic acidosis corrects pH toward baseline values, with a high degree of interindividual variability.

For thousands of years, has been widely used as an herbal medicine to treat some diseases and symptoms, including respiratory, gastrointestinal and urogenital ailments. The present study was adapted to document and assemble existing information about and its evidence-based ethnopharmacological activities, with brief reviews on the description, geographical distribution, ecology, medical uses and phytochemistry. A literature review and information up to 2024 was performed in various scientific databases, including PubMed, Science Direct and Google Scholar.

Retroperitoneal robotic-assisted laparoscopic pyeloplasty (R-RALP) is the commonest urologic procedure performed in children, entailing retroperitoneal CO2 insufflation and lateral decubitus, whose effects on cardiopulmonary variables are poorly known. We, therefore, studied hemodynamic and respiratory changes due to CO2 insufflation and lateral decubitus in children undergoing R-RALP and their effects on regional tissue oxygenation. Between 1/2021 and 7/2024, children affected by ureteropelvic joint obstruction (UPJO) underwent a pyeloplasty by R-RALP at Necker Enfants Malades Hospital (Paris, France), using a standardized surgical technique and a lung-protecting anesthetic protocol aimed to prevent hypercarbia.

Since infections associated with microbial communities threaten human health, research is increasingly focusing on the development of biofilms and strategies to combat them. Bacterial communities may include bacteria of one or several species. Therefore, examining all the microbes and identifying individual community bacteria responsible for the infectious process is important.

Importance: COVID-19 infection has been associated with acute kidney injury. However, its possible association with long-term kidney function is not well understood.
Objective: To investigate whether kidney function decline accelerated after COVID-19 compared with after other respiratory tract infections.
