Single-cell transcriptomics of bronchoalveolar lavage during PRRSV infection with different virulence.
Nat Commun
January 2025
Functional Genomics & Bioinformatics Laboratory, Department of Animal Science and Technology, Chung-Ang University, Anseong, Gyeonggi-do, 17546, Republic of Korea.
Porcine reproductive and respiratory syndrome virus (PRRSV) causes significant economic losses in the global swine industry due to its high genetic diversity and different virulence levels, which complicate disease management and vaccine development. This study evaluated longitudinal changes in the immune cell composition of bronchoalveolar lavage fluid and the clinical outcomes across PRRSV strains with varying virulence, using techniques including single-cell transcriptomics. In highly virulent infection, faster viral replication results in an earlier peak lung-damage time point, marked by significant interstitial pneumonia, a significant decrease in macrophages, and an influx of lymphocytes.

Ophthalmology, Jawaharlal Institute of Postgraduate Medical Education and Research (JIPMER), Puducherry, India.
Coats-like response refers to a condition where abnormal telangiectatic retinal vessels and aneurysms associated with subretinal exudation are seen in the setting of other ocular or systemic diseases. So far, it has been described with various ocular disorders like retinitis pigmentosa, chronic ischemic branch retinal vein obstruction and pars planitis. A man in his 30s presented with a 1-month history of diminution of vision in the left eye.

BMJ Case Rep

Cardiology, East Cheshire NHS Trust, Macclesfield, UK.
Non-bacterial thrombotic endocarditis (NBTE) is characterised by sterile vegetations on heart valves and often emerges in hypercoagulable states like malignancy. It is frequently underdiagnosed and only comes to light during postmortem examination. Early diagnosis and treatment with anticoagulation can help lower mortality.

Am J Emerg Med
January 2025
Department of Emergency Medicine, Brooke Army Medical Center, Fort Sam Houston, TX, United States of America.
Introduction: Stercoral colitis is a rare but serious diagnosis which is associated with a high rate of morbidity.
Objective: This review highlights the pearls and pitfalls of stercoral colitis, including presentation, diagnosis, and emergency department (ED) management based on the available evidence.
Discussion: Stercoral colitis is an uncommon inflammatory condition of the distal large bowel and rectum resulting from accumulation of impacted stool and is associated with several complications including bowel ulceration, ischemia, perforation, peritonitis, and sepsis.
Oedema index trajectories at heart failure nurse clinics over 6 months after acute heart failure predict patient outcomes: a retrospective cohort study.
Eur J Cardiovasc Nurs
January 2025
Heart Failure Research Center, Division of Cardiology, Department of Internal Medicine, Chang Gung Memorial Hospital, 222 Mai Chin Road, Keelung 20401, Taiwan.
Aims: Fluid accumulation is associated with poor outcomes in patients with heart failure (HF). After acute HF, HF nurses provide home care suggestions based on oedema status assessed at outpatient clinics. However, the pattern of serial oedema changes and their associations with patient outcomes are unknown.
