This observational study focuses on children under 18 years of age with tracheostomies who are followed at the Long-Term Intensive Care Unit LIVA at Karolinska University Hospital in Sweden. It aims to determine how often tracheostomy-related airway complications are asymptomatic or linked to symptoms detected through surveillance airway endoscopy. Additionally, the study evaluates how accurately caregivers and pediatricians can identify symptoms related to serious airway complications. Children scheduled for regular surveillance airway endoscopy under anesthesia as part of their follow-up at LIVA will be included. Upon admission, caregivers complete a questionnaire about possible symptoms of airway complications. The child then undergoes a physical exam and medical history review by a pediatrician following a set protocol. An ENT surgeon, unaware of the questionnaire and pediatrician exam results, performs the airway endoscopy to identify complications. During the study, researchers will compare caregiver and pediatrician reports with findings from airway endoscopy to assess symptom reliability. The main measurements include the proportion of patients with serious tracheostomy airway complications who show no symptoms before endoscopy. The study spans two years, with ongoing surveillance and the collection of data on symptoms and complications. Ethical approval has been obtained to conduct this research.

This research aims to evaluate whether creating dedicated HIV teams in hospitals across ten European countries can increase HIV testing rates among patients showing signs of HIV-related conditions. The study uses a stepped-wedge design, where hospitals switch from routine care to the new intervention in sequence. This approach compares outcomes before and after the teams are in place, helping to understand the impact of the intervention across various locations and medical specialties. The intervention involves establishing local HIV teams led by specialists and supported by nurses and data experts. These teams identify patients needing HIV tests through electronic health records, provide feedback to doctors to encourage testing, offer education to healthcare staff about HIV, reduce stigma, and improve connections to prevention and care services. This program integrates smoothly into regular hospital routines and aims to close gaps in HIV diagnosis. Participants HIV testing rates will be monitored by reviewing records before and after the intervention. Researchers will also assess new HIV diagnoses, changes in testing patterns by country and specialty, and healthcare professionals knowledge and attitudes toward HIV. The study includes ongoing evaluation of how well the teams operate, resource use, and cost-effectiveness. Data collection extends up to several years to observe long-term effects, with continuous monitoring of care access and prevention services.

This research aims to compare the effectiveness of monitoring blood sugar levels at 1 hour versus 2 hours after meals in pregnant women diagnosed with Gestational Diabetes Mellitus who require treatment. The study focuses on understanding which monitoring time better supports managing blood sugar during pregnancy to improve outcomes for both mother and baby. Participants are pregnant women attending an antenatal clinic and are treated with metformin, insulin, or a combination. Participants will be randomly assigned to monitor their blood sugar either 1 hour or 2 hours after meals using self-monitoring of capillary blood glucose. Their blood sugar is tracked at seven staggered points to provide a detailed profile. This monitoring continues until delivery, with participants followed regularly in the research clinic. Throughout the study, women will have regular visits to assess their health and that of their baby. Researchers will collect data on mode of delivery, gestational age at birth, and fetal weight. They will also monitor maternal and perinatal complications from randomization to delivery. The total participation lasts from enrollment until the birth of the baby, allowing detailed observation of pregnancy outcomes related to the glucose monitoring method.

This study evaluates whether a mobile phone-based mHealth Behavioural Change Communication BCC educational intervention can improve the adoption and exclusive use of Liquid Petroleum Gas LPG for cooking among households in semi-rural Bangladesh. Household air pollutants HAP from biomass fuels such as wood, agricultural residue, and cow dung expose almost 3 billion people worldwide, including 89% of people in Bangladesh. In the earlier GEOHealth study, 24 months of LPG use reduced personal PM2.5 exposure by about 58.2% and produced changes in innate immune and inflammatory responses, while chronic cardio-pulmonary markers remained relatively stable. More than 70% of households continued using LPG after the earlier study, although not exclusively. The investigators will conduct a large household-level randomized controlled trial using an mHealth-based educational intervention and will continue following the cohort. The study will examine the long-term effects of HAP reduction on subclinical measures of cardiovascular and pulmonary dysfunction, innate and inflammatory immune function, and antibody response to vaccines. Personal 24-hour and area-wise 5-day exposure to PM2.5 and black carbon will be repeatedly assessed before and after the intervention. Lung function and lung pathology will be assessed using spirometry, Chest X-ray, and high-resolution computed tomography of the chest. Cardiovascular measures will include blood pressure and EKG, while metabolic dysfunction will be assessed using HbA1c and fasting lipid profile. Immune function will be evaluated through immune cell phenotyping, functional cytotoxic killer cells, and oxidative stress of lymphocytes.

This research aims to evaluate a 5-session cognitive behavioral program called 1MoreStep, designed for Black women living with HIV who have experienced intimate partner violence in the past two years. The study focuses on teaching skills to access personal and external strengths, safety strategies, knowledge about HIV care and stigma, communication skills to handle stigma, and addressing barriers to HIV care. It also examines the programs acceptability and feasibility among participants. Participants are randomly assigned to either the 1MoreStep intervention or an equal attention control group. The intervention includes seven group sessions and one individual session held weekly, led by experienced facilitators from the Black community. Sessions cover topics such as safety planning, HIV care engagement, stigma communication, and goal setting using cognitive behavioral skills. The control group attends weekly support group sessions that cover general health topics important to Black women living with HIV but not directly related to the interventions goals. Throughout the study, participants complete assessments at baseline, 3 months, and 6 months to measure changes in safety strategies and HIV care engagement. Measures include surveys, medical record reviews, and interviews to evaluate treatment acceptance, session attendance, and participant experiences. The study spans approximately 6 months post-baseline, with follow-up surveys and qualitative interviews to explore program fit and barriers to participation.

This research aims to examine the effects of an 8-week artificial intelligence-based structured exercise program on posture in healthy adults aged 18 to 25 years. Posture is the arrangement of body parts relative to each other, influenced by gravity, muscle tension, and bone structure. The study focuses on common posture disorders in young adults and uses measurements like the craniovertebral angle, thoracic kyphosis, and lumbar lordosis to assess changes. Participants will be randomly assigned to one of two groups. One group will perform exercises guided by an artificial intelligence application called Musclewiki alongside a physiotherapist, practicing three times a week for 8 weeks. The other group will not perform any exercise during this period. Posture measurements will be taken before and after the 8-week program using a mobile app to evaluate angles related to head, shoulder, and spine alignment. During the study, participants will have posture assessments using frontal and lateral images analyzed by the Posture Screen Mobile app. The primary outcome is the change in craniovertebral angle after 8 weeks. Secondary outcomes include changes in thoracic kyphosis and lumbar lordosis angles. The study will monitor participants throughout the 8-week period, with evaluations before and after the intervention to understand the exercise programs impact on posture.

Researchers are evaluating the effectiveness of a six-month virtually-delivered dietary education program called PEDALL to prevent overweight and obesity during maintenance chemotherapy in children and adolescents with acute lymphoblastic leukemia ALL. The study focuses on English and Spanish speaking families and considers key genetic and sociodemographic risk factors that may affect weight gain during treatment. Participants will be randomly assigned to one of two groups the PEDALL intervention group or the standard of care SOC group. The PEDALL group will receive 26 contact hours of specialized nutrition education through weekly one-hour virtual sessions over six months. The SOC group will receive printed educational materials and nutritional care according to their institutions usual practices. During the study, participants and their caregivers will engage in nutrition education and counseling sessions. Researchers will assess weight status, body mass index trajectories, lifestyle behaviors, and the influence of genetic and sociodemographic factors over time. The main goal is to prevent unhealthy weight gain during maintenance chemotherapy and improve long-term health outcomes for childhood ALL survivors. The study will last up to 3.5 years for primary outcomes, with additional follow-up extending to four years.

Researchers are investigating the relationship between obesity and type 2 diabetes, conditions influenced by both genetic and environmental factors. This study aims to better understand how different genetic variations affect gene expression in tissues involved in glucose and lipid metabolism, which may contribute to what is called diabesity, a combined condition of diabetes and obesity. The study uses advanced genomic techniques and bioinformatics to analyze these factors in both humans and animal models. Participants in this observational study are grouped based on their body mass index BMI and diabetes or glucose intolerance status. Groups include individuals with BMI 35 kgm2 with diabetes, glucose intolerance, or without diabetes, as well as those with BMI < 27 kgm2 and BMI between 27 and 35 kgm2 without diabetes. Samples are collected during abdominal surgeries such as bariatric surgery or cholecystectomy to study gene expression and metabolic pathways. During the study, researchers collect biological samples at baseline and follow participants over several years to assess changes in gene expression and insulin resistance. They also evaluate clinical and biological features before and after bariatric surgery at 1, 2, and 5 years. The primary measurement focuses on gene expression in tissues related to glucose metabolism. This long-term observation helps to understand the genetic and phenotypic factors influencing obesity and diabetes, with participation lasting up to 5 years.
