NCT03351426
The purpose of this study is to examine the effects of noninvasive neuromodulation with transcranial direct current stimulation (tDCS) aimed at enhancing the excitability of the left prefrontal cortex in middle-aged women with excess body weight. This is a randomized, parallel, double-blind study with a duration of 4 weeks. Outcome measures will include changes in performance in a computerized task assessing executive functions, subjective measures of food craving and appetite and changes in body weight.
NCT01537029
To determine the effect of weight on doxorubicin and cyclophosphamide plasma clearance in participants who are normal weight (body mass index \[BMI\] \< 25 kg/m2, overweight or class I obese (BMI 25-34.9 kg/m2), or class II-III obese (BMI ≥ 35 kg/m2). The hypothesis is that participants who weigh more will have higher doxorubicin and cyclophosphamide clearances than participants who weigh less. Restated, the area under the drug-concentration time profile, also known as the AUC, in participants will decrease as participant weight increases.

Central venous catheterization (CVC) in ICU is very common. It is associated with many complications. These complications are now well identified in the literature. They are primarily mechanical, infectious and thrombotic events. Many measures are taken to reduce them as the choice of insertion site, strict aseptic technique during insertion and type of catheter used. However, despite these measures, it appears that the incidence of these complications is still high. The technique of ultra-sound guided (USG) catheter insertion has shown its effectiveness in reducing complications in the general ICU population. The increase in obesity in the general population is accompanied by an increase in the obese population in the ICU (BMI \> 30 kg.m-2). Many studies have investigated the effect of obesity on morbidity and mortality in ICU. Some studies found a higher rate of catheter infections in obese patient. Moreover, insertion of central venous catheter is technically more difficult in obese patients. To the investigators knowledge there are no studies on the impact of USG central venous catheterization in obese patients in ICU. The objective of this prospective randomized controlled study is to demonstrate the superiority of USG central venous catheterization (jugular or femoral) on complications in a population of obese patients. 450 patients will be included and dispatched in two groups (jugular or femoral) according to the chosen site of catheter insertion. In both groups, patients will be randomized in the USG technique or the usual anatomical technique. The rate of complications (mechanical, thrombotic or infectious) will be the primary endpoint. Secondary endpoints will be the following: rate of catheter colonization, rate of catheter-related bacteremia, rate of failure during insertion, number of punctures, procedure timing and mortality The investigators hope to establish a benefit in the use of USG central venous catheterization in obese ICU patients and thus contribute to improve the quality of care.
