Evaluate the outcomes of NKF as an initial method for biliary access.
The goal of this clinical trial was to compare two different oral hygiene instruction methods on oral hygiene behavior in older adults. We also wanted to evaluate the self-perception of oral health changes with each instruction method. The main questions we aim to answer were: - Which method has better results in changing oral hygiene habits? - Which method has better results in reducing bacterial plaque? Participants: - Completed a questionnaire about socioeconomic aspects and oral hygiene habits; - Were examined to assess their oral hygiene status; - Completed a questionnaire about self-perception of oral health; - Received oral hygiene instruction (depending on the group: Generalised Approach or Personalised Technique). Two months later, they were assessed again on oral hygiene habits, oral hygiene status, and self-perception of oral health.
Prior research has not assessed the value of remote patient monitoring (RPM) systems for patients undergoing anticoagulation therapy after cardiac surgery. This study aims to assess whether the clinical follow-up through RPM yields comparable outcomes with the standard protocol. A crossover trial assigned participants to SOC-RPM or RPM-SOC, starting with the standard of care (SOC) for the first 6 months after surgery and using RPM for the following 6 months, or vice-versa, respectively. During RPM, patients used the Coaguchek© to accurately measure International Normalized Ratio values and a mobile text-based chatbot to report PROs and adjust the therapeutic dosage. The study assessed patients' and clinicians' experience with RPM and compared direct costs.
The primary goal of this study is to assess in vivo the efficacy of the insoles, in improving venous return in subjects affected by this problem after 14 days of the initial measurements, by self-assessment, filling-in questions regarding Quality of Life, in comparison with a control group. The secondary goal of this study is to assess in vivo the acceptability of the subjects regarding the same medical device, after 14 days of using the medical device, by selfassessment, filling-in subjective evaluation questions.

The primary endpoints are SBRT feasibility and dosimetrical reproducibility to HDR brachytherapy, inter/intra-fractional target motion assessment and toxicity rates. Secondary endpoints are quality of life measures, local control, disease free survival and overall survival.
The present study is a crossover randomized controlled trial that aims to investigate the effects of concurrent exercise training over usual care on physical performance, muscle strength, and myokines concentrations in frail older adults living in nursing homes.The main questions it aims to answer is: Can a 12-week exercise intervention provide beneficial effects on physical performance, muscle strength and myokines among the most frail participants? Researchers will compare this intervention to usual care. Nursing homes (comprising participants) will be randomly assigned to a sequence of interventions (AB or BA), being A -exercise and B usual care. Participants will be assessed before and after each intervention.
Pediatric obesity is considered one of the most important public health problems worldwide due to its high prevalence and associated comorbidities. Physical exercise has been shown to have an important role in the treatment of obesity and associated cardiometabolic dysfunction. Small-sided soccer games (SSSG) have been explored as a promising way of increasing physical exercise due to its benefits on cardiometabolic health and high degree of enjoyment, which favors long-term adherence. The objective of this research is to determine the effects of a 16-week high-intensity SSSG-based exercise intervention on cardiometabolic risk factors, physical fitness, adherence to 24-hour movement patterns, enjoyment and adherence to the intervention in adolescents with metabolic dysfunction and compare them to the effects of a traditional soccer intervention. The investigators hypothesize that high-intensity SSSG are more effective in improving the obesity-related cardiometabolic risk profile in adolescents with cardiometabolic dysfunction compared to traditional soccer training. A parallel 3-arm randomized controlled trial will be conducted in adolescents with overweight and metabolic dysfunction between 11 and 15 years of age. The inclusion criteria are: (i) age between 11-15 years at the time of intervention start; (ii) overweight or obesity (BMI> 85th percentile); (iii) Abdominal obesity ≥90th percentile as assessed by waist circumference or a waist-to-height ratio ≥ 0.5; (iv) willing to participate in the study regardless of possible group allocation; (v) informed consent given by participant and legal representatives. Exclusion criteria: (i) health condition not compatible with participation in physical exercise; (ii) history of recent musculoskeletal injury hindering exercise participation; (iii) concurrent participation in a structured weight loss or exercise program. Those eligible to participate in the study will be randomly assigned to one of three groups: i) SSSG group, ii) traditional soccer play group (TSG), or, iii) non-exercise intervention control group (CG). Participants in both exercise intervention groups will undergo a 16-week intervention. The SSSG group will participate in a high-intensity small-sided soccer games training, while the TSG will undergo a technical and tactical skills training program and traditional soccer training. The CG participants will continue with regular school physical education classes without any additional intervention. Before and after the intervention, all participants will be assessed for cardiometabolic and hepatic biochemical markers, physical fitness, anthropometry and body composition, blood pressure, objective daily physical activity and sleep quality, and perceived enjoyment of participation in SSSG and TSG. The primary outcomes of the study will be waist circumference and cardiorespiratory fitness. The study protocol was approved by the Ethics Committee of the Faculty of Sport of the University of Porto and by the Scientific Ethics Committee of the Adventist University of Chile.
Ingestion during labor is an issue that has attracted the attention of the scientific community in recent decades, with different practices occurring in different countries. However, the scientific evidence of the risk / benefit of fluid intake in labor is still not fully understood. The aim of this study was to contribute with data that allow the evaluation of an eventual relationship between the amount of fluid ingested during labor and the type of delivery, the duration of labor, the occurrence of nausea and vomiting and the value of the Index of Apgar at the 1st and 5th minutes of the newborn's life. An observational study, with a convenience sample of 144 parturient from two hospitals of Portugal were employed. The analysis was based on recording the before mentioned variables and potentially confounding variables. In order to control for potential sources of bias in the study and to guarantee the homogeneity of the sample in the specific statistical treatment of each dependent variable, an observation grid was drawn up for all the participants in the study. Twenty eight of the parturient, the parturient's ambulation, labour analgesia, food intake during labour, the use of oxytocin during labour, the occurrence of postpartum complications, the birth weight of the newborn and the occurrence of birth complications.
