AI Article Synopsis
Article Abstract
Background: The monocyte distribution width (MDW), a novel inflammatory biomarker reflecting morphological changes in response to inflammation, has been shown to be useful in identifying COVID-19 infection or predicting death. However, data on the association with predicting the need for respiratory support are still limited. The aim of this study was to determine the association of MDW with the need for respiratory support in patients with SARS-CoV-2 infection.
Patients And Methods: This is a single-center retrospective cohort study. Consecutive hospitalized COVID-19 adult patients who presented at the outpatient department (OPD) or emergency department (ED) between May and August 2021 were enrolled. Respiratory support was defined as any one of the following: conventional oxygen therapy, high-flow oxygen nasal cannula, noninvasive, or invasive mechanical ventilation. The performance of MDW was measured using the area under the receiver operating characteristic (AuROC) curve.
Results: Of the 250 enrolled patients, 122 (48.8%) patients received respiratory support. The mean MDW was significantly higher in the respiratory support group: 27.2 ± 4.6 vs 23.6 ± 4.1 ( < 0.001). The MDW ≥ 25 had the best AuROC characteristics of 0.70 (95% CI: 0.65-0.76).
Conclusions: The MDW is a potential biomarker that may aid in identifying individuals at risk of requiring oxygen support in COVID-19 and can be easily implemented in clinical practice.

Background And Objectives: The pharmacokinetics (PK) of piperacillin/tazobactam (PIP/TAZ) is highly variable across different patient populations and there are controversies regarding non-linear elimination as well as the fraction unbound of PIP (f). This has led to a plethora of subgroup-specific models, increasing the risk of misusing published models when optimising dosing regimens. In this study, we aimed to develop a single model to simultaneously describe the PK of PIP/TAZ in diverse patient populations and evaluate the current dosing recommendations by predicting the PK/pharmacodynamics (PD) target attainment throughout life.

Objectives: To present cases of rapid onset obesity with hypothalamic dysfunction, hypoventilation, and autonomic dysregulation (ROHHAD) and discuss management insights.
Methods: Case records of patients fulfilling the criteria for ROHHAD and presenting to the Pediatric Endocrinology Division of All India Institute of Medical Sciences, New Delhi, between July 2019 and June 2024 were reviewed for clinical features, treatments, and outcomes.
Results: Five patients (4 boys, 1 girl) presented at a median age of 4 y (range 3.
Background: Although Interprofessional Education (IPE) is an important component of medical education, it has only recently come under consideration in Sub-Saharan Africa. IPE occurs when two or more professions learn from, about and with each other regarding effective collaboration and the improvement of health outcomes. Current academic programs focus more on traditional approaches to training physicians, pharmacists, respiratory therapists, physiotherapists and nurses like they were independent entities.

Background/objectives: The coronavirus disease (COVID-19) pandemic has significantly impacted global health, with Malaysia reporting over 5 million cases as of May 2024. While symptoms like fatigue and breathlessness are commonly reported among COVID-19 patients, limited research exists on the vocal and pulmonary conditions of individuals with long COVID symptoms. This study aims to assess vocal impairments and pulmonary function differences between long COVID patients and healthy controls, addressing gaps in understanding how long COVID affects vocal and respiratory health.
