NCT05598684
A prospective, longitudinal, multicentre, observational cohort follow-up study conducted in France.
NCT06452979
Objectives: Variability of clinical phenotypes in childhood obstructive sleep apnoea (OSA) has prompted research for biomarkers to identify patients at risk of developing OSA-related complications. Upper airway inflammation is documented in children with OSA. Whether it is related to end-organ morbidities and systemic inflammation is under-explored. The primary objectives of our study are 1)To evaluate inflammatory biomarkers with the use of nasal epithelial lining fluid (NELF) collected by nasal strips as a representation of upper airway inflammation in children with OSA compared to non-OSA controls; 2) To evaluate the associations between NELF biomarkers with ambulatory blood pressure (ABP) outcomes in children with OSA. Hypothesis to be tested: Inflammatory biomarkers in NELF in children with OSA are altered when compared with non-OSA controls and correlated with ABP outcomes. Design and subjects: A prospective case-control study. Non-obese Chinese children aged 6-11 years old with habitual snoring (≥3 nights per week) and polysomnography (PSG) confirmed OSA (OAHI of ≥1/hour) will be recruited as cases. Non-OSA children with OAHI \< 1 event/h will be recruited as controls. All subjects will undergo evaluation including questionnaires, anthropometric measurements, PSG, 24-hour ABP measurement, blood and NELF sampling. Primary outcome measure: Profile of inflammatory biomarkers in the NELF. Analysis: Correlations between NELF inflammatory biomarkers with polysomnographic and ABP measurements will be evaluated by regression analysis. Expected results: This study will provide novel and important information regarding upper airway inflammatory biomarkers in children with OSA and their relationship with blood pressure outcomes.

Eligible subjects will receive 3 bi-weekly treatments (once in 2 weeks) with Trim II hands-free applicator belt according to the study protocol.Study duration for each subject is approximately 6 months (including screening, 3 treatments and 2 follow-up visits at 1 and 3 months post last treatment).
NCT03933800
The main objective of this study is to evaluate the efficacy of high-flow nasal cannula (HFNC) therapy in children with OSA. Children and adolescents aged 6 to 18 years old with a diagnosis of moderate-to-severe OSA requiring CPAP therapy will be recruited. In phase 1 study, eligible subject will be recruited for HFNC therapy titration with PSG to assess treatment efficacy. After titration, if HFNC therapy is shown to be effective, the participants will be recruited into the phase 2 intervention period to evaluate the compliance and quality of life with HFNC therapy. At baseline and follow-up visits, neurobehavioural and quality of life surveys will be completed, compliance data will be obtained.
NCT06447610
Lateral arm free flap harvesting has been well described, it however remains underused compared to other free flaps such as radial forearm and anterolateral thigh free flap. Due to its easy harvesting, low donor site morbidity, versatility as well as useful possibilities of modifications it should be considered more often as valuable reconstruction option in head and neck defect. With this publication we want to describe the operative technique, illustrate it with postoperative pictures and describe the outcome with 8 of our cases operated at University Hospital In Lausanne, Switzerland. The aim of this study is to be a useful tool for young surgeons and demonstrate the advantages of this useful flap in head and neck reconstructions.

NCT05746741
With funding through the United States Department of Agriculture (USDA) and Tufts University's Telehealth Intervention Strategies for WIC (THIS-WIC), Michigan's (MI) WIC department will pilot telehealth opportunities as a means of delivering services to WIC Clients. This video conferencing pilot looks to improve and/or remove barriers. Implementing a pilot program in select local agencies to utilize technology would allow clients to connect with a WIC Registered Dietitian (RD) or an International Board-Certified Lactation Consultant (IBCLC). Videoconferencing could open new opportunities for leveraging the extensive expertise of the nutrition and lactation workforce in WIC agencies to address rural and remote locations and travel considerations. The purpose of this study will be to evaluate the effectiveness of this telehealth solution.
NCT05887869
With funding through USDA and Tufts University's Telehealth Intervention Strategies for WIC (THIS-WIC) project, the South Carolina WIC department will be implementing a telehealth solution for nutrition and breastfeeding support. The purpose of this study is to evaluate this telehealth solution. The research/evaluation involves completing online surveys. The evaluation will focus on participant satisfaction, usage of the telehealth solution, and use of information collected on the WIC participant through the WIC management information system (MIS). It is hypothesized that the telehealth solution will increase WIC participant's satisfaction with nutrition and breastfeeding support while also reducing the burden of attending in-person care.
NCT02956824
Prospective multicenter study assessing the incidence of inflammatory and structural lesions seen on MRI of the SI joints in a consecutive population of women aged 18-50 years old. The study hypothesis is SpA may be misdiagnosed on MRI in post partum women due to increased stress on the joint following pregnancy and childbirth, as MRI of the SI joints may show lesions that could mimics axial spondyloarthritis. The primary objective of this study is to determine the incidence of SI lesions seen at MRI in women. The secondary objectives are to compare the incidence and pattern of MRI inflammatory and structural lesions of the SI joints and to determine the factors associated with inflammatory or structural changes of the SI joints in a population of women. the investigators will especially compare the population of women within a year after childbirth versus the population of women who never gave birth or who gave birth over 24 months ago or more.
NCT00804323
Argon laser trabeculoplasty (ALT) with 100 ms pulses is an effective therapy for lowering intraocular pressure (IOP). Similar reductions in IOP have been achieved using ns (SLT) and microsecond (MLT) pulses, which produce less thermal damage to trabecular meshwork (TM). Lack of clinically visible changes may make the accurate alignment of subsequent pulses difficult. We describe a novel technique - Patterned Laser Trabeculoplasty (PLT) using the PASCAL Photocoagulator system, and its preliminary evaluation in patients with open angle glaucoma.
NCT04139616
The high incidence and variety of conduction disturbances post-TAVR represents a major challenge in the periprocedural management of TAVR recipients. Despite the growing body of knowledge on this topic, the large variability in the management of these complications has translated into a high degree of uncertainty regarding the most appropriate treatment of a large proportion of such patients. The implementation of a pre-specified treatment strategy translating into a more uniform practice regarding the management of conduction disturbances post-TAVR applied to a large cohort of patients would permit to identify the benefits and drawbacks of each specific aspect of the treatment algorithm proposal. This may also help to improve both the management and clinical outcomes of the complex group of patients with conduction disturbances associated with TAVR. In the end, the final objective of a pre-specified strategy for managing conduction disturbances post-TAVR should be to obtain a low rate of PPM without increasing the risk of sudden death or life threatening arrhythmic events following hospital discharge, and all this while avoiding an excessive prolongation of the hospitalization period following the TAVR procedure.

NCT06435741
Surgical lymph node dissection is the key to advanced gastric cancer. In recent years, after the overall implementation of standard D2 dissection, lymph node dissection for gastric cancer began to explore the direction of D1+ again. Current clinical studies of gastric cancer lymph node dissection based on intraoperative fluorescence navigation show that non-tumor specific lymph node fluorescence navigation surgery can only increase the total number of lymph nodes detected and ensure the completion of the dissection but not the accuracy. The sensitivity and specificity of the tracer metastatic lymph nodes are 56.3% (410/728), respectively. Specificity 46.1% (2669/5785). Tumor specific tracing of positive lymph nodes is the key to achieve accurate lymph node dissection for gastric cancer. Although tumor specific tracers are developing rapidly and related clinical studies are gradually being carried out, there are few reports on specific clinical studies on lymph node metastasis, suggesting that lymph node tracing is still a difficult problem. Previous basic studies have suggested that integrins play an important molecular biological role in the process of tumor lymph node metastasis. In the early stage, 99mTc3PRGD2 SPECT-CT showed good lymph node imaging effect in lung cancer and breast cancer, and 99mTc-oncoFAPI PET-CT also showed good lymph node imaging effect in gastric cancer. Therefore, this study aims to explore the application prospect of 99mTc3PRGD2 and other probes in molecular imaging of gastric cancer metastatic lymph nodes and guidance of lymph node dissection and tracer, so as to accumulate preliminary clinical data for exploring corresponding fluorescent probes for intraoperative tracer of gastric cancer lymph nodes.
NCT04631185
This study is a prospective, multi-institutional, noninferiority, randomized control trial that will compare the efficacy of two antibiotic treatments in preventing SSI in patients receiving immediate breast reconstruction with tissue expanders (TE-BR). The patients will be randomly assigned to one of the two treatment groups. One group will receive a single dose of antibiotics just before surgery and if necessary, more doses during the surgery. The other group will receive the same treatment as the first group, along with an additional week of antibiotics after surgery. The study will assess the rates of SSI from the two groups. It will also assess the type, duration and method (oral vs. intravenous) of subsequent antibiotic use for patients who develop SSIs in each group.
NCT04639193
Obstructive sleep apnea (OSA) is common and associated with many adverse health consequences, but many patients are unable to tolerate standard therapies such as continuous positive airway pressure (CPAP) and thus remain untreated. Single-drug therapies have shown promising results in treating sleep apnea, but on average patients have only experienced partial relief. Multi-drug therapy may offer a more effective treatment approach. The goal of this study is to test the effect of combination therapy with three FDA-approved drugs (Diamox \[acetazolamide\], Lunesta \[eszopiclone\] +/- Effexor \[venlafaxine\]) on OSA severity and physiology.
