Calisthenics-Based Intervention in Adolescents: Effects on Strength, Body Composition, Eating Habits, and Self-Concept

This study evaluates the effectiveness of a school-based calisthenics intervention in promoting physical activity and improving health-related outcomes in adolescents. Physical inactivity during adolescence is a growing public health concern associated with increased risks of obesity, poor physical fitness, and reduced psychological well-being. Schools provide an optimal environment to implement structured interventions that encourage lifelong healthy habits. Calisthenics is a form of exercise that uses bodyweight movements to improve strength, flexibility, and coordination. It is cost-effective, accessible, and does not require specialized equipment, making it particularly suitable for school settings. The present study integrates a structured calisthenics program into regular physical education classes. A total of 100 students aged 13 to 16 years will be randomly assigned to either an experimental group, which will participate in the calisthenics program, or a control group, which will follow the standard physical education curriculum. The intervention will last 12 weeks, with three sessions per week. Primary and secondary outcomes will be assessed at baseline and after the intervention. These include physical fitness (muscle strength), body composition, dietary habits, and self-concept. Strength will be measured using a handgrip dynamometer, body composition through anthropometric assessment, dietary habits through a validated questionnaire, and self-concept using the Self-Concept Form-5 (AF5). Findings from this study will provide evidence regarding the feasibility and effectiveness of implementing calisthenics in school settings as a strategy to improve both physical and psychological health in adolescents.

Using Real-Time Lung Visuals to Reduce Mental Strain and Improve Diagnosis Speed

The goal of this clinical simulation study is to learn if a "Digital Twin" graphical lung display reduce the mental workload of clinicians. The study also evaluates if this helps physicians diagnose and manage ventilator-related crises more effectively than standard ventilator screens. The main questions it aims to answer are: Does the Digital Twin display lower the cognitive stress (mental workload) experienced by clinicians during a crisis? Does the Digital Twin display reduce the time it takes for clinicians to identify specific respiratory complications? Does the use of real-time physiological visualization improve the accuracy of clinical decision-making? Researchers will compare the performance of clinicians using a standard ventilator display (the "Black Box" condition) to their performance when provided with an additional synchronized 3D lung and advanced waveform display (the "Digital Twin" condition). Participants will: Complete four randomized mechanical ventilation crisis scenarios using a high-fidelity lung simulator (ASL 5000). Manage scenarios involving high airway resistance, low lung compliance, auto-PEEP, and patient-ventilator asynchrony. Undergo a 14-day "washout" period between sessions to ensure no memory bias between the control and intervention groups. Complete a NASA-TLX survey after each scenario to measure their perceived mental, physical, and temporal demand.

Psychosocial Teleassistance Programme for Adults With Spina Bifida

This clinical trial assesses the effect of a telecare psychosocial intervention designed for adults with spina bifida. The intervention consists of 10 weekly 1.5-hour group sessions, followed by two 3-month follow-up sessions. Each group will consist of 6 to 7 individuals. The intervention is aimed at strengthening aspects of self-concept, self-esteem, social skills and aims at a reduction of symptomatology and a general improvement of psychological well-being.

Contemplative Practice for Well-being and Self-Deconstruction in Women

This randomized controlled trial aims to evaluate the effectiveness of a contemplative practice called Feeding Your Demons (FYD), based on a secular adaptation of Tibetan Buddhism, in improving psychological well-being, body image, body acceptance, compassion, and self-deconstruction in adult women. Participants will be randomly assigned to either FYD or an active control group practicing mindfulness meditation. Psychological variables will be assessed before and after the intervention, and at a six-month follow-up. Additionally, a qualitative exploration will be conducted through interviews with a subgroup of participants.

Impact of Nipple Reconstruction in Mastectomized Patients Using Cross-Linked Hyaluronic Acid Injection.

This study evaluates the impact of hyaluronic acid (HA) injection for nipple projection following mastectomy, as a complement to areola micropigmentation. While micropigmentation is standard in nipple-areola complex (NAC) reconstruction, HA use remains novel, with limited data on psychosocial, sexual, and aesthetic outcomes. A sequential explanatory mixed-methods design will be used. In Phase 1, a randomized controlled trial will compare two groups: one receiving NAC micropigmentation alone (control) and the other receiving micropigmentation plus HA-based nipple projection (intervention). A total of 138 participants will be recruited at the Areolar Micropigmentation Unit of Germans Trias i Pujol University Hospital (Barcelona) over 36 months. Outcomes will include psychosocial and sexual well-being, satisfaction with breast and nipple appearance, and nipple projection, measured using the Spanish BREAST-Q, a custom satisfaction tool, and calipers. Phase 2 will involve a qualitative phenomenological study using semi-structured interviews with a purposive sample from the intervention group. Thematic analysis will explore body image, emotional and social well-being, and overall satisfaction, using NVivo software. This is the first study assessing HA nipple reconstruction by advanced practice nurses using validated patient-reported outcomes. While the BREAST-Q is appropriate, it may not fully capture emotional nuances, justifying qualitative exploration. HA durability is estimated at 6-9 months, but residual volume and satisfaction over time remain underexplored. HA's aesthetic footprint may allow reduced dosages in future applications. This minimally invasive technique may reduce the need for surgical nipple reconstruction. Conducting the procedure in a nurse-led setting is novel and may enhance patient-centered care and the role of nursing in post-mastectomy recovery. The study complies with the Declaration of Helsinki and Spanish biomedical regulations. Ethical approval was obtained. Participants will provide informed consent, and data will be anonymized and securely stored.
