A 73-year-old man presented with nausea, abdominal discomfort, and distention persisting for the past five days. He had previously been diagnosed with stage III peripheral CD4+ T cell lymphoma and had initiated chemotherapy comprising vincristine two weeks prior to presentation. An evaluation revealed diffuse colon distention and pneumatosis intestinalis without mechanical obstruction, consistent with acute colonic pseudo-obstruction.

Disruptions to the skin microbiome can impact immune function, leading to inflammatory and autoimmune conditions. The importance of pH for the microbiome is paramount.

- Autologous platelet concentrates, known for their growth factors, may enhance success rates in treating macular holes, prompting this study to assess their efficacy and safety through a comprehensive review and meta-analysis.
- The research included six studies with 616 patients, revealing that platelet concentrate therapy significantly improved anatomical closure of macular holes compared to controls, although no major differences were found in reopening rates, visual acuity improvements, or complication rates.
- Despite promising results for smaller holes, the authors emphasize the need for more extensive research with standardized methods and longer follow-up to better evaluate the therapy's overall effectiveness and safety.
Background: Wearable sensors are rapidly evolving, particularly in health care, due to their ability to facilitate continuous or on-demand physiological monitoring.
Objective: This study aimed to design and validate a wearable sensor prototype incorporating photoplethysmography (PPG) and long-range wide area network technology for heart rate (HR) measurement during a functional test.
Methods: We conducted a transversal exploratory study involving 20 healthy participants aged between 20 and 30 years without contraindications for physical exercise.
Early subclinical macular disease in asymptomatic patients with primary antiphospholipid syndrome: A quantitative multimodal retinal evaluation.
Lupus
January 2025
Purpose: To perform a quantitative multimodal evaluation in 25 patients with primary antiphospholipid syndrome (PAPS) without ocular complaints and to compare them with 25 healthy individuals.
Methods: A structural and functional ophthalmological evaluation using optical coherence tomography angiography (OCTA) and microperimetry (MP) exam in 25 patients with PAPS, followed at a tertiary rheumatology outpatient clinic, was performed. All ophthalmologic manifestations were documented and subsequent statistical analysis was performed for comparative purposes, with significance set at < 0.
