Background: Throughout the history of spinal deformity there have been continuous advances in the surgical treatment. Although many techniques have been successfully developed despite the anatomy complex, screw placement still remains difficult with a significant risk of misplaced implants. The O-ARM guided Navigation is a scanner that allows imaging of screws intraoperatively and could be a tool to facilitate screw revision and reduce the occurrence of misplaced implants. Methods: This is a prospective and randomized clinical study that will be carried out at the University Hospital of the Federal University of Piaui, which provides exclusive assistance to patients of the Unified Health System (UHS), in northeastern Brazil.
Infertile women attending for PGT at the Centre of Assisted Reproduction and Embryology, Queen Mary Hospital and Kwong Wah Hospital will be recruited during ovarian stimulation for IVF. Subsequently, they will be randomly assigned on the day of oocyte retrieval by a laboratory staff into one of the following two groups in a 1:1 ratio : (1) the microfluidic chip group and (2) the density gradient centrifugation group for sperm preparation and subsequent use in fertilization. Other IVF procedures will be the same as the standard practice of the Centre. Both women and clinicians will be blinded from the group allocation i.e. a double blind study.
Rationale: Chronic obstructive pulmonary disease (COPD) is characterised by a high prevalence of peripheral muscle dysfunction, which can have significant clinical consequences, including decreased exercise capacity, reduced quality of life, and even a higher mortality rate. Reduction of lung hyperinflation using bronchoscopic lung volume reduction treatment with one-way endobronchial valves (EBV) is a minimally invasive intervention which improves exercise capacity and physical activity in patients with severe emphysema. This positive effect is also related to weight gain and alterations in body composition. The physiologic and structural adaptations of skeletal muscle function after EBV treatment has never been investigated before. Objective: To investigate the physiological and structural adaptations of peripheral muscle function at a cellular level in response to EBV treatment. Study design: A single center, prospective clinical trial with a single-arm pretest-posttest design. Patients with severe emphysema who will receive a bronchoscopic lung volume reduction treatment are asked to undergo additional in-magnet exercise testing and muscle biopsies before and after placement of EBVs. Study population: Patients with severe emphysema who are scheduled to undergo EBV treatment. Main study parameters/endpoints: The difference in quadriceps phosphocreatine concentration (PCr), quadriceps inorganic phosphorus concentration (Pi), and quadriceps pH at rest, during progressive exercise, and recovery rate will be measured by 31P-MRS to assess the physiological effect of EBV treatment on skeletal muscle function and its bioenergetics. Furthermore, we will perform a detailed histological and biochemical analysis of muscle fiber type composition, mitochondrial density, master regulators of muscle oxidative programming, and mitochondrial respiration before and after EBV treatment.
The goal of this clinical trial is to compare standard treatment (5 days of doxycycline) vs single dose doxycycline for the prevention of tick-borne relapsing fever in soldiers who found bite marks on their bodies after an activity that includes contact with the ground or staying at a site suspected of being infected with ticks. The main question[s] it aims to answer are: - Testing whether preventive treatment with a single dose of doxylin at a dose of 200 mg is effective in preventing recurrent fever, and if so, at what rate - Checking the profile and rate of side effects in each one of the proposed treatment protocols Participants will be treated with standard treatment (5 days of doxycycline) or single dose doxycycline.
The goal of this clinical trial is to develop and test an educational program about dementia in older adults living with epilepsy. The main questions it aims to answer are: 1. Can providing education on healthy aging, chronic disease management, dementia, and modifiable lifestyle dementia risk factors improve dementia knowledge and health literacy among older adults with epilepsy? 2. Can aging related education and resources improve quality of life among older adults with epilepsy? Participants will: - Complete a 12-week group educational program. - Complete pre- and post-program evaluation.
Robotic right hemicolectomy with intra-corporeal anastomosis may have better short-term recovery outcomes and decreased incidence of incisional hernia when compared to the laparoscopic actual standard of care, for similar safety outcomes.
The purpose of this study is to determine whether Motivating Youth to Reduce Infections, Disconnections, and Emotion dysregulation (MY-RIDE) decreases substance use , to determine whether MY-RIDE increases human immunodeficiency virus (HIV) prevention strategies and to evaluate MY-RIDE effects on willingness to take Pre-Exposure Prophylaxis (PrEP), stress, substance use urge, and use of mental health and substance use services when compared to attention control youth
A previous study completed in 2022 (NCT05158179) was conducted using cohorts of healthy controls, and adults with general laryngopharyngeal disorders. This study will expand on the previous research to include a separate cohort of adults being seen in clinic for an existing laryngopharyngeal disorder resulting from previous radiation or other cancer treatments.
The goal of this clinical trial is to compare the effectiveness of a mobile health intervention in adolescents (14-17 years) with overweight or obesity. The main question[s] it aims to answer are: 1) is a digital-based diet quality intervention for adolescents with overweight or obesity feasible and 2) is there preliminary effectiveness in improving diet quality? Participants will: 1. Complete three-day 24-hour dietary recalls 2. Collect urine samples 3. Wear a continuous glucose monitor, sleep tracker, and physical activity tracker Researchers will compare control and intervention groups to see if diet quality and meal timing traits improve as assessed by 24-hour dietary recalls, a novel urine biomarker, and continuous glucose monitoring (CGM).
This is a randomized controlled trial with 8 schools (4 intervention and 4 wait-list control schools) including 160 caregivers (80 teachers and 80 parents), with the aim of pilot testing the implementation process, feasibility, acceptability, usage patterns, and efficacy of the mHealth Toolkit for Wellness & Empowering Lives of School Community (mWEL) in Uganda. The mWEL-App is a preventive intervention tool for teachers and parents as a self-help support modality. Caregivers who need support in navigating the toolkit will be supported by P-CHWs. The investigators hypothesize that: 1) relative to the control, caregivers receiving the mWEL will have better efficacy outcomes (mental health literacy, and mental health outcomes); and 2) mWEL implementation will have high acceptability, appropriateness, and feasibility.
