Filter by:Healthful eating is a core component of a healthy lifestyle that is associated with lower risk of obesity and chronic disease. Although adolescent health promotion programs have been extensively evaluated and applied in English-speaking Western developed nations, there is very little published literature in the Russian context. Our study seeks to determine the relative effectiveness of a healthy lifestyle intervention consisting of nutrition education at a Russian camp. Investigators will determine the impact of behaviorally focused nutrition education on nutrition knowledge, food choice, attitude, and self-efficacy for healthful eating, compared to standard nutrition education.
The overall purpose of this project is to advance understanding of the neurophysiological features of Rett syndrome (RTT), MECP2 Duplication (MECP2 Dup) and RTT-related disorders (CDKL5, FOXG1) to gain insight into disease pathogenesis, with an emphasis on identifying biomarkers of disease evolution and severity. This specific study is intertwined to the core study Natural History of Rett Syndrome and Related Disorders (RTT5211), which characterizes range of clinical involvement and genotype-phenotype correlations and will provide phenotypical data for determining the clinical relevance of the neurophysiologic parameters; study subjects here are co- and primarily enrolled in RTT5211. The proposed studies will serve as basis of future translational investigations, including further refinement of biomarkers, development of outcome measures, and clinical trials per se.
The aim of MATRIX-DPRS is to assess the clinical and organizational impacts of the use of the medication record, opened, filled and managed by pharmacists (from private office and hospital units) by hospital physicians in private and public healthcare establishments (volunteers), for three clinical contexts: anaesthesiology visit before surgery, medications abuse and emergency hospitalization, medications and elderly hospitalisations.
This study includes an inclusion visit, 2 visits to the Rennes University Hospital and the filling of two on-line questionnaires. The first visit to the University-Hospital of Rennes, during which a blood sample will be taken, morpho-anatomic measures (height, weight, hip and size), impedancemetry and resting energy expenditure by indirect calorimetry will be carried out in the Clinical Investigation Unit. During this visit, the volunteers will also have to bring a sample of urine and faeces previously collected at home. The two on-line questionnaires (hedonic and caloric evaluation of foods and beverages on photos) will have to be completed by the volunteers between the first and the second visit to the University-Hospital. Finally, the volunteers will go to the University-Hospital of Rennes for the second visit, on the Neurinfo platform, during which they will be subjected to a cognitive two-choice test based on food and drink pictures, during fMRI. Before and after the fMRI session, an assessment of the state of hunger, thirst, and general status of the volunteer will be carried out using a numerical scale ranging from 1 to 10.
This non-interventional, observational study investigates the course of symptoms in patients with functional dyspepsia under treatment with a fixed combination of pepsin and amino acid hydrochloride over a period of approximately 6 weeks. The change of the Gastrointestinal Symptom Score (GIS©) was the primary parameter for the assessment of efficacy and was performed at baseline, after 3 and 6 weeks of treatment respectively. Safety measures included recording of AEs and physical examination as well as measurement of vital signs. The aim was to observe 100 patients during the course of this non-interventional study.
Clozapine has consistently shown to be a superior drug for psychosis in patients who do not respond to other treatments, but its mechanism of action remains unknown. The overall goal of this study is to examine the functional neural circuitry that underlies successful treatment with clozapine, which may lead to the identification of biomarkers that will allow for more efficient use of clozapine, as well as additional treatment targets for patients with refractory illness.
Acne vulgaris is a complex skin disorder involving multiple abnormalities of the pilosebaceous unit. Acne is the most common skin disease during puberty and worsens throughout adolescence. However, epidemiological studies suggest that acne can arise at any age, most frequently affecting individuals between puberty and 30 years of age, with 79%-95% of subjects aged between 16 years and 18 years and 80% of subjects between puberty and 30 years of age. Acne is considered the main reason for consultation with the dermatologist in institutional and private clinical practice. Clinical features include seborrhoea, non-inflammatory lesions, inflammatory lesions and various degrees of scarring. There are many classifications of acne and scarring severity. Moderate to severe acne is about 15-20%. Facial acne scarring affects both sexes equally and occurs to some degree in up to 95% of cases. There is a significant correlation between the initial acne grade and the overall severity of scarring at all sites and in both sexes. This would suggest that treatment aimed at reducing the severity of acne might reduce the incidence of scarring. Both superficial inflammatory acne lesions as well as deep nodular lesions seem capable of producing scars. Conventional therapies recommended for the treatment of acne vulgaris include retinoids, benzoyl peroxide (BPO), antibiotics, and hormonal therapy. Combination therapy using agents with complementary mechanisms provides the opportunity to target multiple pathogenetic causes of acne vulgaris. The combination in gel with 0.1% adapalene and 2.5% BPO is a once-daily treatment of acne vulgaris. In several double- blind, randomized controlled trials (RCTs), the Adapalene-BPO (A-BPO) combination therapy applied once daily for 12 weeks significantly reduced the number of both inflammatory and non-inflammatory lesions in subjects with moderate acne vulgaris. In Mexico there is an available commercial product of this combination (Effezel®; Galderma). The limitation of this topical therapy is the low tolerability by patients as they can experiment several levels of irritation, erythema, dryness, desquamation, burning, and itching), and patients are advised to expect these side effects, which contribute to discontinue therapy if it becomes severe. On the other hand, 5-methyl-1-phenyl-2-(1h)-pyridone or pirfenidone (PFD) is a wide-spectrum antifibrotic drug that modulates diverse cytokines action, involving TGF-β, TNF-α, epidermal growth factor, platelet-derived growth factor, VEGF, IGF-1, fibroblast growth factor, interferon-γ, interleukin (IL)-1, IL-6, and IL-8 and it has shown promising effects in vitro and in vivo settings. Also, PFD has proven effective in the prevention and regression of pulmonary fibrosis, peritoneal sclerosis, hepatic cirrhosis, uterine fibromyoma, left ventricular fibrosis, renal interstitial fibrosis, and breast capsular contracture in experimental models. A recently open phase II clinical trial evaluated the therapeutic use of PFD gel in localized scleroderma. Results showed it acts on both the inflammatory and the fibrotic phases. The other component of Zaxcell is modified-diallyl disulfide oxide (M-DDO) an antimicrobial and antiseptic agent, which has been proved in patients with chronic diabetic ulcer as a potent germicide and has show to increase the beneficial effect of PFD preventing infections, accelerating and improving ulcer resolution. (Observations not published). According to this, the investigators believe that Zaxcell (PFD + M-DDO) could play an important role in the modulation of inflammatory and scarring process in acne. The investigators hypothesis is that PFD in patients with moderate to severe acne modulates amplification of the inflammatory response, regulating the inflammasome activation, macrophage polarization and its activity in regulating the wound healing process of the skin in an early fashion. Zaxcell is an innovative gel with a synergetic mode of action that could modulate the inflammatory response. Furthermore, has antiseptic properties and regulates the process of wound healing, fibrogenic and scarring process. In vitro and in vivo studies provide an initial body of evidence on the safety and clinical benefits of PFD, the main component of Zaxcell as a promising candidate for the treatment of moderate to severe acne.

The clinical investigation will be conducted at approximately 5 sites in the United States involving 20 patients.
This phase Ib trial studies the side effects and best dose of niraparib when given together with radium Ra223 dichloride in treating subjects with prostate cancer that keeps growing even when the amount of testosterone in the body is reduced to very low levels and has spread from the primary site to the bone. Radium Ra 223 dichloride, acts like calcium to target cancer in the bones and may deliver radiation directly to the bone tumors, limiting damage to the surrounding normal tissue. Niraparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving radium Ra 223 dichloride and niraparib may work better in treating subjects with hormone-resistant prostate cancer metastatic to the bone.
