NCT ID: NCT02813707 Recruiting - Quality of Life Clinical Trials

Prospective Study to Determine Long Term Impact of Bariatric Surgery

BS-PART2
Start date: April 2016
Phase: N/A
Study type: Observational

The World Health Organization (WHO) statistics, in 2008, there were more than 1.4 billion adults, aged 20 and older, and were overweight. Of these over 200 million men and nearly 300 million women are obese. Body Mass Index (BMI) more than 30 is considered as obese and increasingly bariatric surgery is the commonest way used nowadays to lose weight. Moreover, surgery will influence many other health factors and parameters. Many studies prove the improvement of metabolic and psychological status of patients post bariatric surgery. In addition, many vitamins will be affected and should be replaced. This research study is continuation (PART 2) of previously approved study (approval: 13/54). Brief findings of the study are attached. Our aim in this part of the study to assess long term the impact of bariatric surgery on metabolic, nutritional and quality of life status on patients post bariatric procedure of at least 12 months post-surgery follow up. As we noted in our previous initial study that there is significant loss the collection of the data due to "no show" for proper follow up routine care. Previously it was approved to consent patients by phone calls and extract information regarding Quality of Life (QoL) post-surgery. This will be replaced by seeing the patients in the outpatient clinic and providing the necessary information and consent.

NCT ID: NCT02696421 Recruiting - Clinical trials for Energy Expenditure During Ramadan Fasting

Ramadan and Energy Expenditure Study

RAMEE
Start date: June 2015
Phase:
Study type: Observational

Ramadan fasting entails abstinence from eating and drinking between dawn and sunset. During this month major changes in meal times and patterns, sleeping times and activity occur. Starvation is known to lead to a compensatory reduction in energy expenditure. However, the Ramadan fast is not synonymous with starvation as it involves intermittent periods of fasting followed by gorging. People who fast during Ramadan feel less energetic. However, little is known about the effects of this religious practice on energy metabolism. . The aim of this study is to assess energy dynamics before and/or after and during Ramadan fasting in non-obese participants. Resting metabolic rate (RMR), thermic effect of food (TEF), active energy expenditure (AEE) and total energy expenditure (TEE) in free-living conditions will be measured . Indirect calorimetry will be used to assess RMR and TEF, doubly labeled water will be used to measure TEE and activity monitors will measure physical activity. In addition, body composition analysis will be performed by bio-electrical impedance. Blood sample will be taken to exclude medical factors affecting energy metabolism.

NCT ID: NCT02317718 Recruiting - VITAMIN D Disorders Clinical Trials

Serum Vitamin D Level and Its Association With Ovarian Reserve and IVF Outcome

Start date: December 2014
Phase: N/A
Study type: Observational [Patient Registry]

Vitamin D has a major play in bone and calcium metabolism. Vitamin D deficiency (below 20 ng/ml) has also been linked to adverse health outcomes such as malignancy, cardiovascular disease, immune functioning, and glucose metabolism. Recent data from retrospective and prospective trials have demonstrated contradictive results concerning the role of vitamin D in female reproduction and IVF outcome. Some studies have found that women deficient in vitamin D had lower ovarian reserve and significantly lower clinical pregnancy rates when compared to patients who were sufficient levels in vitamin D. Some studies also demonstrated that serum 25-OH-D3 levels correlates with antimullerian hormone (AMH) levels in women of advanced reproductive age. It may also have a role to play in endocrine dysfunction and abnormal folliculogenesis in polycystic ovaries . The aim of this prospective cohort study including infertile women undergoing IVF treatment is to investigate the association between serum 25-OH- D3 levels and parametres of ovarian reserve (AMH, antral follicle count, number of oocytes collected) and clinical pregnancy and miscarriage rates .

NCT ID: NCT01865227 Recruiting - Obesity Clinical Trials

Obesity Surgery, Counseling, and Psychological Well-Being

Start date: November 2012
Phase: N/A
Study type: Interventional

Obesity has become a global epidemic causing enormous human and economic costs. Incidence rates have doubled over the last few decades and obesity-related illnesses such as diabetes and cardiovascular diseases now constitute one of the major contributors to the global burden of disability. Overall, obesity has been recognized as one of the most pressing public health concerns worldwide and effective treatment and prevention strategies are urgently required. While behavioral and pharmacological treatments (e.g.low calorie diets, medication) are successful means for overcoming overweight and mild obesity, more severe cases of obesity usually fail to respond to such interventions. As a result, the demand for weight loss surgery is growing among this population. However, uncertainties about the effectiveness of obesity surgery persist and high relapse rates (i.e. weight regain) are common. Further research in this field is needed to identify risk factors that may trigger relapse and to understand patients' treatment needs in greater depth. Previous studies have pointed toward high levels of mental health problems among patients. However, the impact of preoperative psychopathology on actual surgery outcomes remains unclear. Similarly, few studies have investigated the effect of postoperative therapy on patients' psychological functioning and weight loss patterns. Research addressing these gaps is imperative to establish best-practice approaches. This challenge applies in particular to Middle East and North Africa(MENA) countries where research in the field of bariatric surgery and related mental health is largely missing. This is a major concern given the fact that the MENA region experienced the highest increase in overweight and obesity in recent decades compared to other countries. The proposed study aims to address this deficiency by examining obesity surgery patients in two Arab countries (UAE and Jordan). The goals of the project are to investigate the nature and extent of psychological health concerns among these patients before and after surgery and potential associations with treatment outcomes. Moreover, it will test the efficacy of post-operative counseling to improve weight loss and psychological health. For this purpose, a randomized clinical trial design will be employed so that cause and effect relationships between postoperative counseling and treatment outcomes(i.e. weight loss and psychological functioning) can be examined experimentally. The study will start by assessing participants' psychological health prior to surgery by using standardized self-report measures. After surgery, participants will be randomly assigned to either the intervention condition consisting of 3-monthly post-operative medical checkups plus group counseling or the treatment as usual condition (i.e. 3-monthly standard medical checkups only). Additionally, participants' psychological health will be reassessed in both groups at 3, 6, 9 and 12 months after surgery. The benefit of the experimental study design is that it allows comparing patient outcomes between groups while at the same time controlling for a wide range of potential confounding variables. The data collected are expected to make a significant contribution to the treatment challenge of one of the most pressing public health concerns worldwide. Study results will add to clinical practice by broadening and deepening our knowledge of the treatment needs of obese patients. By identifying psychological health concerns that may threaten successful treatment outcomes high-risk patient groups can be recognized early, which in turn may help to reduce postoperative weight regain and other complications. To the best of the PI's knowledge, the proposed work would be the first study of this kind in the Arab world. Findings will be helpful for developing culturally sensitive and evidence-based best-practice guidelines, which are vital to achieve satisfying long-term outcomes. Moreover, study results will be relevant for research communities and practitioners outside the MENA region since empirical support for the effectiveness of obesity surgery remains weak internationally.
