Citobot AI for real-world cervical cancer screening using colposcopy imaging
Open AccessMarcela Arrivillaga, Daniela Neira et al.ARTICLEFrontiers in Public Health2026
Background: Cervical cancer remains a major cause of morbidity and mortality among women, particularly in low- and middle-income countries, where delays in screening and diagnostic follow-up limit early detection. Artificial intelligence applied to medical imaging may strengthen screening programs by improving accuracy, consistency, and timeliness in resource-limited settings. Objective: This study aimed to evaluate the internally validated scree…
AC-2020-12-1420.R1 – HIV care providers’ familiarity, concerns, and attitudes about HIV PrEP in Colombia
Open AccessJorge Martinez-Cajas, Boris Alvarado et al.ARTICLEAIDS Care2022
In 2019, Colombia approved the combination of tenofovir disoproxil fumarate/emtricitabine for HIV Pre-Exposure Prophylaxis (PrEP). Therefore, we conducted a situational analysis in HIV-care providers to identify barriers and facilitators for PrEP implementation. A survey was applied to a non-probabilistic sample of health care workers of HIV-specialized clinics. We examined PrEP awareness and familiarity, comfort with PrEP-related activities, per…

Colombia has a mixed public-private health care system, and although official data indicate more than 95% of health coverage, research in this field has demonstrated the persistence of barriers to accessing health care services. This study aimed to analyze the conceptual framework of health services accessibility and develop measurement tools for its assessment using primary data and also to propose a method for ascertaining health services acces…

Open AccessMérida Rodriguez-Lopez, Mérida Rodríguez‐López et al.ARTICLERevista Peruana de Medicina…2016
The profiles of high-frequency patients differ from control patients with respect to factors related to capacity, need, and willingness; in particular, the latter were independently associated with frequent attendance. Notably, the presence of an anxious or depressive disorder doubled the risk of highfrequency attendance at a primary care facility

Studies on HIV/AIDS treatment adherence have been carried out in a limited number of geographic settings, but few studies have explored it in people of higher socioeconomic status in Latin America. This qualitative study explored and compared determinants of adherence behaviors among 52 HIV-positive Colombian women in medium and high socioeconomic positions (SPs). Findings indicated that the two SP groups reported high adherence behaviors related…

Reliability and validity of the Student Perceptions of School Cohesion Scale in a sample of Salvadoran secondary school students
Open AccessAndrew Springer, Andrew E Springer et al.ARTICLEBMC International Health and…2009
BACKGROUND: Despite a growing body of research from the United States and other industrialized countries on the inverse association between supportive social relationships in the school and youth risk behavior engagement, research on the measurement of supportive school social relationships in Central America is limited. We examined the psychometric properties of the Student Perceptions of School Cohesion (SPSC) scale, a 10-item scale that asks s…
