Introduction: It is currently unclear whether patients with rheumatoid arthritis have similar functional outcomes after total hip arthroplasty (THA) as those with osteoarthritis, particularly given that rheumatoid arthritis may have systemic manifestations in terms of pain and function. The purpose of this study was to compare patient-reported outcome measures between patients with rheumatoid arthritis and matched control patients with osteoarthritis who underwent direct anterior THA.

Methods: All patients who underwent direct anterior THA from 2010 to 2022 at a single academic institution were retrospectively reviewed.

Introduction: Anxiety and depression are major causes of disability in Arab countries, yet resources for mental health services are insufficient. Mobile devices may improve mental health care delivery (mental m-Health), but the Arab region's mental m-Health app landscape remains under-documented. This study aims to systematically assess the features, quality, and digital safety of mental m-Health apps available in the Arab marketplace.

(Cb), the causative agent of Q fever, replicates within host macrophages by modulating immune responses through poorly understood mechanisms. Long non-coding RNAs (lncRNAs) are emerging as critical regulators of inflammation, yet their role in Cb pathogenesis remains largely unexplored. Here, we employed a global transcriptomic approach to identify lncRNAs specific to Cb infection in THP-1 derived macrophages, compared to 15 other microbial infections.

Background: Almost 40% of individuals at ultra-high risk (UHR) for psychosis experience persistent attenuated psychotic symptoms (APS) yet it is unclear (1) whether they share overlapping clinical and functional outcomes compared to individuals who transition to psychosis, (2) when symptom and functioning trajectories begin to diverge between UHR individuals with different clinical outcomes, and (3) whether non-remission (persistent APS or transition) can be predicted using baseline and/or longitudinal data.

Study Design: Participants were drawn from 2 randomized clinical trials: Neurapro (n = 220; discovery sample) and STEP (n = 180; external validation sample). First, 12-24 month symptoms and functioning were compared between UHR individuals with persistent APS, sustained remission, or transition to psychosis.

The composition of the respiratory track microbiome is a notable predictor of infection-related morbidities and mortalities among both adults and children. Species of which are largely present as commensals in the upper airway and other body sites, are associated with lower colonization rates of opportunistic bacterial pathogens such as and . In this study, -mediated protective effects against and were directly compared using and models.
