NCT ID: NCT03784508 Recruiting - Morbid Obesity Clinical Trials

Identification of Biomarkers of Response After Bariatric Surgery in Morbidly Obese Patients

PREDI-BAR
Start date: April 1, 2018
Phase:
Study type: Observational

The prevalence of obesity in Spain is about 21.6%. The discouraging results provided by dietary treatment, together with the lack of funding for pharmacological treatment, have led to the progressive use of bariatric surgery (CB). Besides weight loss, CB associates a beneficial effect on metabolic comorbidities. However, 25-30% of operated patients present a weight response considered inappropriate, they do not resolve their comorbidities and/or present a weight-regain shortly after surgery. Therefore, predictive strategies are necessary to allow a correct selection of obese patients who are candidates for CB. The main hypothesis of the study is that various factors such as psychopathological profile, body composition and metabolic alterations related to morbid obesity can influence the response to bariatric surgery.

NCT ID: NCT03788681 Recruiting - ICSI Clinical Trials

Luteal Phase Support With Estradiol In Poor Responders Undergoing In Vitro Fertilization

Start date: April 1, 2018
Phase: Phase 3
Study type: Interventional

The role of progesterone (P) supplementation in the luteal phase of in vitro fertilization (IVF) cycles is well established world-wide , but the influence of the luteal phase estradiol level on implantation is not clearly defined . There is a significant difference in estradiol levels between fertile and infertile cycles of fertile women who underwent donor insemination.

NCT ID: NCT03791853 Recruiting - Breast Neoplasms Clinical Trials

Light-CT in the Diagnosis of Breast Tumor and Lymph Node

Start date: April 1, 2018
Phase:
Study type: Observational

Intraoperative pathological diagnosis such as frozen section and imprint cytology is not routinely recommended in clinical practice because of time and accuracy concerns. Full-field optical coherence tomography (FF-OCT) is a new optical imaging technique that could generate sectioning tomogram from fresh tissue and provide close-to-pathology depiction of the morphological structure and pathological changes in minutes without conventional tissue preparation, slicing, and staining, and dynamic cell imaging (DCI) added the viability information of cells/tissue, which could be more important in cancer diagnosis. This study was to evaluate the feasibility and diagnostic value of FF-OCT and DCI in breast lesions and lymph node specimens during breast cancer surgery. We evaluated normal breast tissue, benign breast lesions, breast cancer and axillary lymph node specimens resected from patients undergoing breast surgery.

NCT ID: NCT03830099 Recruiting - Clinical trials for Mechanical Ventilation

Inhomogeneous Ventilation in Adult Post-neurosurgical Patients

Start date: April 1, 2018
Phase:
Study type: Observational

Inhomogeneous ventilation was more likely to happen in patients after general anesthesia. Inhomogeneous ventilation may associate with ventilator-induced lung injury. A large number of post-neurosurgical patients was delayed extubation and received mechanical ventilation, so that, inhomogeneous ventilation was more likely to happen in the population. Electrical impedance tomography (EIT) is an noninvasive, radiation-free, high temporal resolution, relatively cheap technique in monitoring ventilation distribution bedside. The investigators aimed to investigate the incidence of inhomogeneous ventilation and factors associated with inhomogeneous ventilation in post-neurosurgical patients under mechanical ventilation.

NCT ID: NCT03841071 Recruiting - Quality of Life Clinical Trials

A Clinical Feedback System in Ostomy Care

Start date: April 1, 2018
Phase:
Study type: Observational

Background: Living with an ostomy can be challenging and adapting to life with an ostomy can be particularly complex, with regard to both the physical and psychosocial aspects. Follow-up with a stoma care nurse is usually performed after surgery to support the adaptation process. In this project, we describe a new model of ostomy care, where a clinical feedback system (CFS) is implemented in order to improve the adaption process of patients with an ostomy. We also present a plan for evaluating patients experience with the CFS and their clinical outcomes. Methods: We include patients who had recently performed colostomy, ileostomy, or urostomy surgery. The intervention includes self-reported measures for adaptation to life with an ostomy and health-related quality of life (HRQoL), as well as patient experiences and satisfaction recorded by the clinical feedback system. The measures are electronically assessed before each clinical consultation at 3, 6, and 12 months after surgery. The scores are instantly analysed and graphically presented for use during the consultation and the patient and stoma care nurse can discuss the findings. Patient experiences and satisfaction with care will be measured with the Generic Short Patient Experiences Questionnaire. Adaptation to the life with ostomy will be measured with the Ostomy Adjustment Scale, and HRQoL with the Short Form 36. Discussion: This study presents a novel approach that could lead to improved consultation, more patient involvement, and better adaptation to life with an ostomy.

NCT ID: NCT03847363 Recruiting - Acute Pain Clinical Trials

The Influence of Different Anesthesia on Acute and Chronic Postsurgical Pain After Thoracic Surgery

Start date: April 1, 2018

NCT ID: NCT03885375 Recruiting - Autoimmune Diseases Clinical Trials

Diagnostic and Imaging Indicators of Immunocardiomyopathic Patients

Start date: April 1, 2018
Phase:
Study type: Observational [Patient Registry]

Cardiac involvements in autoimmune diseases (AD) is common but underestimated and an early detection remains a clinical challenge for lacking of efficient imaging methods. The objective of the study was to investigate LV myocardial abnormalities in AD patients by multimodal cardiac imaging, including speckle-tracking echocardiology (STE), cardiac magnetic resonance imaging (CMRI) and positron emission tomography (PET).

NCT ID: NCT03886558 Recruiting - Healthy Clinical Trials

Multicomponent Program on a Group of Nonagenarians

ELTGN
Start date: April 1, 2018
Phase: N/A
Study type: Interventional

Introduction The promotion of physical activity among older adults is considered to be one of the main actions that can result in more successful aging. Currently, there are few studies focusing on the effects of long-duration physical activity interventions in older adults. Thus, the purpose of the following study was to analyze the effects of an 8-month multicomponent intervention program on cardiorespiratory capacity, body composition, and strength in a group of nonagenarians. A secondary objective was to determine if the impact of the program differed according to the participants' way of life (institutionalized vs. community dwelling). Methods Participants Participants in this research represent a subset from an ongoing study aimed at collecting baseline and follow-up data over three years, to evaluate the health-related changes observed in a cohort of older adults f The present research was carried out on the basis of data obtained from the individuals in this sample who participated in a multicomponent intervention program offered to the inhabitants of the said region and who met the following inclusion criteria: a) being ninety years of age or older; and b) holding a medical certificate confirming their suitability for sport. The exclusion criteria were a) lack of independent ambulation (walking with an assistive device); b) recent upper or lower limb injuries; c) neurological or orthopedic diagnosis in upper or lower-extremities. Intervention A multicomponent intervention program was developed consisting of two 60-minute sessions per week, held on non-consecutive days, for a period of 8 months. The sessions consisted of a warm-up phase (10') in which individuals performed joint mobility exercises and walked at a rate of 3 km/h. Afterwards, muscular strength work was carried out on the upper and lower limbs, including calisthenic exercises, and the use of dumbbells or medicine balls (1-3kg). Generally, the exercises were organized in two sets of 10-15 repetitions, resting for two minutes between sets. Communal ball games and relay games were then practiced (over a distance of 30 meters). Finally, 10 minutes were devoted to relaxation and stretching exercises. multicomponent intervention program was designed and monitored by a specialist in gerontogymnastics. Evaluations Two weeks before the start and after the end of the exercise program, a series of assessments were carried out, which were monitored by specialists in physical exercise and sport, who did not know whether those evaluated were institutionalized or not. Body composition Weight was measured to the nearest 0.1 kg using a Tefal digital scale (type PP1200VO) with the participants wearing light clothing and no shoes. Height was measured to the nearest millimeter with a field stadiometer (Seca 220). The body mass index (BMI) was calculated taking the body weight in kilograms and dividing it by the height in meters squared (BMI: kg/m2). Densitometry Bone mineral density content (BMD) of the femoral neck was measured using a dual energy X-ray absorptiometry (DEXA) machine (Hologic QDR 1000®), which reported BMD in grams per square centimeter (g/cm2). This method was used to ensure better reproducibility, a lower radiation dose and better image resolution (Watts 2004). The minimum significant alteration, with a 95% confidence interval, was 4.7%. Muscular strength Upper limb muscle strength was assessed with the Handgrip Test (HG) on the right hand using a dynamometer (SH5001, SAEHAN Corporation, South Korea). For each measurement, patients were asked to perform their maximum voluntary contraction for 5s. Each measurement was repeated three times with patients resting for 30s between trials. The best performance was recorded for further analysis. Lower limb muscle strength was assessed with the Isometric Knee Extension Test (KNEE), performed three times on the right leg with participants seated on a custom-built chair with a load cell (Vetek VZ101BS, Vaddo, Sweden). For each measurement, participants were asked to perform their maximum voluntary contraction for 5 s. The test was repeated 3 times and participants rested for 2 min between trials. The best performance from the three trials was considered for further analysis. Cardiorespiratory fitness In order to assess the effect of the program on the participants' cardiorespiratory fitness, the six-minute walk test (6MWT), was performed, following standard procedure. The subjects were instructed to walk at their own pace from one end to the other of a 100-foot-long measured distance in an enclosed, level, corridor, and to cover as much ground as possible in 6 min. They were allowed to stop and rest during the test, but were instructed to resume walking as soon as they felt able to do so.

NCT ID: NCT03917537 Recruiting - HNSCC Clinical Trials

WGA in Platinum-refractory HNSCC Underwent Nivolumab

Start date: April 1, 2018
Phase:
Study type: Observational

To choose a subgroup who could clearly benefit from Nivolumab, we are proposing a prospective observational study. Whole-genome study (WGS) analysis will be performed on archived cancer tissues from patients who were (1) cisplatin-refractory and subsequently (2) received Nivolumab (at least 4 doses) and (3) had completed imaging response evaluation at 3-4 month after Nivolumab. The estimated sample size was designed to be 80, including 20 responders and 60 non-responders (1:3 design) after Nivolumab alone at a dosage of 2-3mg/kg every 2 weeks (+/- 7 days could be allowed), given the minimal requirement of statistical significance. The specific bio-signature(s) found in this prospective observational study could possibly greatly contribute to precision immuno-oncology medicine, especially Nivolumab.
