Background: Although isolated terminal ileal ulcerations (ITIUs) are occasionally observed on colonoscopic examination of asymptomatic individuals, their clinical course and guidelines for treatment are unclear.
Objective: To evaluate the clinical course and significance of ITIUs in asymptomatic individuals.
Design: Single-center retrospective analysis.
Setting: University hospital.
Patients And Interventions: All patients diagnosed with ITIUs on colonoscopy from July 2001 to December 2007 were identified. Patients with colorectal symptoms, a history of nonsteroidal anti-inflammatory drug consumption, a history of colorectal surgery, oral or genital ulcerations, and coincidental ulceration in the ileocecal valve or colon were excluded.
Main Outcome Measurements: Colonoscopic findings and clinical courses of patients were analyzed.
Results: Of the 148 included patients, 93 were followed (mean duration, 29.9 months). Of these, 62 showed resolution of ITIU on follow-up colonoscopy, including 60 who resolved without any treatment and 2 who resolved after antituberculosis medication. Follow-up colonoscopy continued to show ITIUs in the remaining 31 patients, only 1 of whom developed typical Crohn's disease, whereas the other 30 showed no significant changes in the lesions (n = 22), partial improvement (n = 6), or waxing and waning endoscopic appearance (n = 2).
Limitations: Retrospective design, relatively short-term follow-up.
Conclusions: Most ITIUs incidentally observed in asymptomatic individuals resolve without any treatment. Even if these lesions persist, it is unusual for them to progress or to cause any symptoms.

Latent tuberculosis prevalence in healthcare workers in Laos: a cross-sectional study.

Background: Individuals with latent tuberculosis infection (LTBI) have a high risk of active infection, morbidity and mortality. Healthcare workers are a group who have increased risk of infection and onward transmission to their patients and other susceptible individuals; however, LTBI is often undiagnosed, and individuals are asymptomatic. Interferon gamma release assays (IGRA) can detect evidence of TB infection in otherwise asymptomatic individuals and are a good indication of LTBI.

Objectives: To determine the prevalence of acromioclavicular (AC) joint and subacromial space imaging abnormalities in asymptomatic adults, with a secondary objective of comparing findings between asymptomatic and symptomatic shoulders within the same study populations.
Methods: We conducted a systematic review of studies examining shoulder imaging abnormalities detected by X-ray, ultrasound (US), computed tomography (CT), and magnetic resonance imaging (MRI) in asymptomatic adults (PROSPERO registration CRD42018090041). This report focuses on AC joint and subacromial space abnormalities.
Stakeholder perspectives on barriers and facilitators to hypertension control in urban Haiti: a qualitative study to inform a community-based hypertension management intervention.

Center for Global Health, Weill Cornell Medicine, 402 East 67 Street, 2 Floor, New York, NY, 10065, USA.
Background: Uncontrolled hypertension is the leading modifiable risk factor for cardiovascular disease mortality and remains high in low-middle income countries like Haiti. Barriers and facilitators to achieving hypertension control in urban Haiti remain poorly understood. Elucidating these factors could lead to development of successful interventions.

Introduction: People Living with Human Immunodeficiency Virus (PLHIV) appear to be at a higher risk of developing sarcopenia. Various factors seem to influence the risk of sarcopenia, and its prevalence may differ depending on the screening tool used. This study aimed to (i) Screen the risk of sarcopenia in PLHIV using the SARC-F and SARCCalf and identify associated factors; (ii) Analyze the agreement between the instruments in PLHIV.

Objectives: It is significant to know how much early detection and screening could reduce the proportion of occult metastases and benefit NSCLC patients.
Methods: We used previously designed and validated mathematical models to obtain the characteristics of LC in the population including undetectable metastases at the time of diagnosis. The survival was simulated using the survival functions from Surveillance, Epidemiology and End Results (SEER) data stratified by stage.
