Objective: The purpose of this study was to describe the diagnostic and therapeutic strategies used by general practitioners (GPs) in patients with lower respiratory tract infections (LRTI).
Methods: Four hundred fifty GPs practicing in France participated in the study; they included 804 patients. The GP recorded social and demographic data and their prescription on a data sheet and responded to a phone questionnaire about their strategy.
Results: Most of the LRTI were acute bronchitis (72%); pneumonia and acute exacerbations of chronic bronchitis were observed respectively in 11% of the patients recruited. Diagnostic criteria used by the GPs were generally auscultation signs in patients with fever, cough and expectoration. Specialized advice (always a chest physician) and hospitalization were exceptional. Prescription of complementary exams was strongly related to the diagnosis of pneumonia (OR = 33.3; CI0.95: 15.48-70.4). Sick leaves were related to general symptoms (fever, asthenia). Antibiotics were prescribed in 95.7% of the patients, mainly aminopenicillin (40.4%) and macrolides (33.2%). Nonsteroidal or steroidal antiinflammatory drugs were prescribed in 72.5% of the patients irrespective of the LRTI diagnosis.
Discussion: The fact that GPs do not often refer patients to specialists or order hospitalization confirms their important role in setting up recommendations. It would also be necessary to develop an education program on better use of antibiotics targeted to GPs and patients.

Double-blind randomised trial of saline solution for gargling and nasal rinsing in SARS-CoV-2 infection.
J Glob Health
December 2024
Department of Anesthesiology, Critical Care and Pain Medicine, UTHealth, Houston, Texas, USA.
Background: Previous studies have shown that hypertonic saline nasal irrigation and gargling reduced the duration of symptoms in upper respiratory infections caused by coronavirus. This study aims to investigate the effects of two saline regimens on symptoms associated with severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2).
Methods: Between 2020 and 2022, individuals aged 18-65 years who tested positive for SARS-CoV-2 infection via polymerase chain reaction (PCR) were randomly assigned to either low- or high-saline regimens for 14 days.
Prediction of inpatient mortality in hospitalised children in low- and middle-income countries: An external validation of paediatric mortality risk scores.
J Glob Health
December 2024
Amsterdam UMC, location University of Amsterdam, Department of Global Health, Amsterdam Institute for Global Health and Development, Amsterdam, the Netherlands.
Background: Risk prediction tools for acutely ill children have been developed in high- and low-income settings, but few are validated or incorporated into clinical guidelines. We aimed to assess the performance of existing paediatric early warning scores for use in low- and middle-income countries using clinical data from a recent large multi-country study in Africa and South-Asia.
Methods: We used data (children across three nutritional strata) from the Childhood Acute Illness and Nutrition (CHAIN) Network cohort study (n = 3101).
Potential Cisatracurium-Induced Malignant Hyperthermia: A Case Report.
Cureus
December 2024
Pulmonology and Critical Care, Marshall University Joan C. Edwards School of Medicine, Huntington, USA.
Malignant hyperthermia is a pharmacogenetic disorder that manifests clinically as a hypermetabolic crisis when a patient with a mutation in the ryanodine or dihydropyridine receptor genes is exposed to neuromuscular blocking agents. Depolarizing neuromuscular agents are known to cause malignant hyperthermia, but cases caused by nondepolarizing agents are rarely reported. We present a case consistent with malignant hyperthermia after receipt of cisatracurium, a nondepolarizing anesthetic agent.

Department of Cardiovascular Medicine, First Affiliated Hospital of Xi'an Jiaotong University, Xi'an, China.
Background: Elevated blood pressure (BP) in childhood is associated with adult hypertension and arterial stiffness. However, the effect of long-term time in target range (TTR) for BP since childhood on the risk of arterial stiffness in midlife remains unclear.
Objectives: The purpose of this study was to determine the independent association of TTR for systolic blood pressure (SBP) from childhood to midlife with arterial stiffness in adulthood.
Objectives: Pneumonia is a major cause of morbidity and mortality among patients in the intensive care unit (ICU). Timely and accurate diagnosis is crucial for effective treatment, but lower respiratory tract sampling techniques vary in sensitivity and specificity. This study aims to compare the diagnostic accuracy of endotracheal aspirate (ETA) with mini bronchoalveolar lavage (mBAL) in detecting bacterial pneumonia in intubated patients, assessing sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of ETA against mBAL, the gold standard.
