Obesity surgery has become commonplace nowadays. This type of surgery is in full swing and although it is mostly beneficial for the health of the patient (reduction of cardiovascular risks, improvement of self image, reduction of osteo-articular risks, etc...) it is however associated with risks. There are several short and long term complications, excluding the ones related to the anesthesia and the post-op recovery: fistulas, abcesses, infections, dysphagia, risks of endobrachyoesophagus, etc... The gastroœsophageal reflux remains by far the most common post-op complaint within patients. Patients can experience symptoms as far as 3 years after the surgery. Medical treatment alone can in most cases lighten the symptoms. However, in some cases, this treatment fails and another type of surgery (bypass) must be undertaken, which is psychologically traumatic for the patient. This retrospective study will analyze a cohort of patients who underwent bariatric surgery (mainly sleeve gastrectomy), in order to identify those at risk of developping gastroœsophageal reflux and how this complication can be avoided in pre-op. The study will also identify cases of invalidating gastroœsophageal reflux that can be solved by obesity surgery.
The purpose of this study is to determine if social media support and financial incentives improve adherence to Truvada as PrEP in African American, Latino and Asian MSM aged 18 to 24 living in the Washington, DC area who are at high risk for HIV acquisition.

Scientific and clinical data report about shortening of QTc-interval in patients treated with cortisone. Peal et al. analyzed chemical suppression of long QT syndrome (Type 2) in an in vivo zebrafish model. Their study revealed that flurandrenolide reproducibly suppressed the long QT phenotype via the glucocorticoid signaling pathway. In contrast to treatment with dexamethasone and testosterone, treatment with pure mineralocorticoid deoxycorticosterone acetate did not suppress long QT phenotype. Knockdown of the glucocorticoid receptor or, conversely, of the androgen receptor showed that flurandrenolide acting through the glucocorticoid receptor shortens ventricular action potentials. The mechanism is distinct from trafficking rescue of the defective zebrafish-ERG channel. The authors discuss that a drug normalizing repolarization would be a novel therapeutic tool in long QT syndrome and conclude that glucocorticoids could be expected to aid in the acute management of patients with long QT syndrome, e.g. in episodes of arrhythmic storm. In addition, corticoid induced normalization of the QT interval is reported in a patient with drug-induced prolongation of the QTc interval. Brostoff et al. report on a patient suffering from mucocutaneous leishmaniasis treated with sodium stibogluconate. During therapy, the QTc interval prolonged and returned to normal within 4 days after starting glucocorticoid therapy with prednisolone 20 mg twice daily. Interrogation of the study: - shortens cortisone the QTc-interval? - how long is the interval until shortening of QTc-interval? - is the effect prolonged? - is the effect dose dependend?
This PAR (participatory action research) study to improve antibiotic prescribing quality in a GPC (general practitioner cooperative) during OOH-care (out-of-hours-care) uses a mixed methods approach using qualitative as well as quantitative techniques. In a first exploratory phase we will work on partnership development and mapping the existing issues. In a second phase the focus will be on facilitating change and implementing interventions through PDSA (plan do study act) cycles. In a third phase outcomes on prescribing quality during and outside office hours will be evaluated. Equally important is the process evaluation and theory building on improving antibiotic prescribing through PAR.
Heart failure is very common and reaches more than 56 million people worldwide. 17 to 45 percent die in the first year of hospitalization. The most affected populations live in Western countries like Europe or the USA. It is defined by a set of signs and symptoms such as dyspnea, asthenia, edema or tachycardia but must be objectified, preferably by ultrasound. Its basic treatment is based on a lifestyle improvement and a reduction of the risk factors (hypertension, dyslipidemia, diabetes, ...), as well as an optimal medical treatment based on ACE inhibitors, B-blockers, ARA2 (Sartans), spironolactone or digoxin. When the optimal treatment is no longer working and that the cardiac desynchronization is demonstrated, be it atrio-ventricular, inter-ventricular or intra-ventricular, the patient can benefit from a three-probes cardiac resynchronization to resynchronize the two ventricles. The classic approach, performed by a cardiologist, is to perform an endovenous procedure in order to place the 3 probes under local anesthesia.The first one goes in the right atrium, the second one in the right ventricle and the third one goes in the left ventricle. It is the placement of this third one that often causes trouble. It is more difficult to place since it must pass through the coronary sinus, outside of the heart, unlike the first two probes that are placed endocavitary. When the practitioner fails to place the probe correctly or obtains inappropriate levels of detection, stimulation, or impedance thresholds, a cardiac surgeon must intervene and carry out a mini-thoracotomy. The CHU Brugmann Hospital is in favor of a mixed surgical approach. The probes are placed by a cardiac surgeon, who first starts by a endo-venous placement under local anesthesia. If that approach fails, the local anesthesia can be transformed into general anesthesia at the same operative time and a mini-thoracotomy is performed. The aim of this study is to evaluate the immediate impact of this surgical management within the CHU Brugmann hospital, in patients suffering from cardiac insufficiency despite proper medication.The hypothesis is that the mixed surgical approach improves the prognosis of cardiac resynchronization.
The purpose of this study is to test the influences of transcranial direct current stimulation (tDCS) on the acquisition of laparoscopic surgical skills. For this purpose, the investigator will compare variants of tDCS in the first of 2 experiments. The second arm of the trial will investigate gaze training in a similar study design. These questions will be evaluated using the validated Fundamentals of Laparoscopic Surgery (FLS) module 1, with the overall goal of developing a surgical training curriculum that achieves expert level skill in an expedited timeframe. This research provides a novel approach to general surgery training that has the potential to reduce the amount of time and repetitions required to achieve expert laparoscopic skills.
The aim of the study is to evaluate the effect of antioxidants on IVF outcome in infertile patients undergoing IVF who are expected to produce low number of eggs compared to a control group. The investigators assumed that the conception rate is higher in those patients taking some antioxidants supplementation. The patients will be given antioxidant drug one month before starting IVF trial once daily by mouth. Uniform protocol of stimulation will be done during the cycle by a type of short protocols known as the antagonist protocol. Egg retrieval will be done under anesthesia. pregnancy test will be done 2 weeks after embryo transfer. The investigators will also assess the number and quality of eggs on the day of egg pick up. In addition, the researchers will assess the number of first and second grade embryos that are put on the day of embryo transfer.
Community based interventions are more acceptable to community members when all participants receive the intervention. A 'stepped-wedge' or 'multiple-baseline' design allows for all participants to receive the intervention by randomizing participants into conditions defined by the length of the baseline period. The primary aim of this pilot study is to gather data that will allow the researchers to estimate parameters, such as the appropriate length of the baseline period that will allow them to power a larger study. A second key aim is to determine if a smartphone intervention that is delivered to parents can increase physical activity in their 6-10 year old inactive children.
The purpose of the OPDEP pilot study is to assess the feasibility of implementing a pre-operative HIV / HCV / HBV screening proposal for all persons over 18 years of age and refer for surgical intervention under general anesthesia in the Department of Stomatology of the Pitié-salpêtrière hospital. Patients undergoing treatment in Stomatology have particular areas at risk for the infections we are looking for: young patients, precarious situation, drug use, migrants ... The aim is to evaluate the conditions for a generalization of screening in the framework of the preoperative assessment.
