Introduction: entering university exposes young people to circumstances of academic stress (AS), a state of tension that affects students and can cause a decrease in physical activity (PA), defined as any body movement. Previous research has shown that a lack of PA is associated with higher levels of AD. Objective: analyze the relationship between physical activity and academic stress in health sciences university students in the city of Cajamarca 2024. Method: a non-experimental cross-sectional study was carried out. The sampling was simple random probabilistic, involving fourth-year health sciences students. The Systemic Cognitivist Inventory to study academic stress (SISCO) and the International Physical Activity Questionnaire (IPAQ) were used. Results: of the 85 participants, 58,8 % were women. 38,8 % of the sample reported doing moderate physical activity, in addition, 90,6 % of the...

Pneumonia is one of the major causes of child mortality, yet with a timely diagnosis, it is usually curable with antibiotic therapy. In many developing regions, diagnosing pneumonia remains a challenge, due to shortages of medical resources. Lung ultrasound has proved to be a useful tool to detect lung consolidation as evidence of pneumonia. However, diagnosis of pneumonia by ultrasound has limitations: it is operator-dependent, and it needs to be carried out and interpreted by trained personnel. Pattern recognition and image analysis is a potential tool to enable automatic diagnosis of pneumonia consolidation without requiring an expert analyst. This paper presents a method for automatic classification of pneumonia using ultrasound imaging of the lungs and pattern recognition.
