Filter by:The goal of this prospective cohort study is to study patients referred for sleep study by in-lab polysomnography in the Jordan University Hospital and the Jordan Hospital. The main aims are: - To prospectively obtain demographic and clinical information of patients referred for a sleep study. - To determine the diagnostic value of facial discoloration as potential marker for obstructive sleep apnea to increase detection rate for the condition. - To establish a correlation between obstructive sleep apnea and vasovagal symptoms with resulting increased smoking tendency and study the effect of treatment on the disorders. - To determine the association between timing of appearance of obstructive sleep apnea symptoms and initiation of smoking.
The goal of this randomized intra-individual design with a split-side axillary approach is to comparing the efficacy of 0.025% tretinoin cream against a cream-based formulation in the treatment of axillary hyperpigmentation associated with acanthosis nigricans. The main questions it aims to answer are: - The efficacy of 0.025% tretinoin cream and cream based in the treatment of axillary hyperpigmentation associated with acanthosis nigricans. - The safety of 0.025% tretinoin cream and cream based in the treatment of axillary hyperpigmentation associated with acanthosis nigricans. Participants were randomly assigned to apply both 0.025% tretinoin cream and the cream-based product on opposing sides of the axillary region.
Acanthosis nigricans (AN) is a dermatosis with aesthetic implications and is characterized by the focal or diffuse development of a velvety, hyperpigmented cutaneous thickening in intertriginous areas. Trichloroacetic acid (TCA), a superficial chemical exfoliative agent has shown efficacy in treating acanthosis nigricans. Data from this would help in establishing it as a treatment of choice thereby lead to reduction in cost and benefit the patient both financially and psychologically.
Acanthosis nigricans (AN) is increasing in its prevalence and is the most prevalent cutaneous manifestation in individuals with obesity. Insulin resistance or hyperinsulinemia is the main pathophysiological mechanism of obesity-related AN. However, the effect of laparoscopic sleeve gastrectomy (LSG) on insulin secretion pattern in Chinese morbidly obese patients with AN is unknown. In these study, the investigators aimed to explore the insulin secretion patterns in Chinese morbidly obese patients with Acanthosis nigricans (AN) and their alterations after LSG.
Mexico is going through a major environmental and nutritional crisis, which is related to unsustainable dietary behaviors. Sustainable diets could solve both problems together. However, in Mexico and the world, an intervention program oriented to promoting sustainable diets has not been designed. This study protocol aims to design a 3-stages, 15 weeks, sustainable-psycho-nutritional digital intervention program whose objective is to promote the adherence of the Mexican population to a sustainable diet and to evaluate its effects on dietary water and carbon footprints, metabolic biomarkers, and gut microbiota of this population. The behavior change wheel model and the guide for digital interventions design will be followed. In stage 1, the program will be designed using the sustainable diets model, and the behavior change wheel model. A sustainable food guide, sustainable recipes, and food plans as well as a mobile application will be developed. In stage 2, the intervention will be carried out for 7 weeks, and a follow-up period of 7 weeks, in a sample of Mexican young adults (18 to 35 years) randomly divided into an experimental group (n=50) and a control group (n=50). The nutritional care process model will be used. Anthropometric, biochemical, clinical, dietary, environmental, socioeconomic level and cultural aspects, nutritional-sustainable knowledge, behavioral aspects, and physical activity will be considered. Thirteen behavioral objectives will be included using successive approaches in online workshops twice a week. The population will be monitored using the mobile application that will include behavioral change techniques. In stage 3, the effects of the intervention will be assessed on the dietary water and carbon footprint, lipid profile, serum glucose, and gut microbiota composition of the evaluated population. It is expected to find improvements in health outcomes and a decrease in dietary water and carbon footprints. With this study, the first theoretical-methodological approach to the sustainable-psycho-nutrition approach will be generated.
This prospective randomized comparative split study will be conducted at the outpatient clinic, Dermatology department, Faculty of Medicine, Cairo University and will include 20 patients with acanthosis nigricans in otherwise healthy individuals which will be recruited and assessed for eligibility for inclusion according to the above criteria. -Evaluation: All patients will be subjected to: Pre-operative preparation: - Informed written consent will be taken from every patient prior to the study. - Detailed history taking including onset, course, duration of the disease and occupation (sun-exposed or not), predisposing factors, history of keloid tendency, associated diseases and previous treatments. - Assessment of skin type, BMI, degree of AN, HbA1C, site of lesions in all patients and degree of improvement. - Photography: will evaluate the clinical response to treatment for each patient Photos will be taken before starting the study, before every session, and two weeks after the last session. - Melanin index (MI) will be measured using reflectance spectrophotometer in order to assess the degree of hyperpigmentation before starting the study and two weeks after the last session. Research Template 8 Final Version: April 2019 - Acanthosis Nigricans Area and Severity Index (ANASI) score (Zaki et al., 2018) will be done for all patients before starting the study and two weeks after the last session. - Patient satisfaction score will be assessed before starting the study and two weeks after the last session. - Patient evaluation (clinical percentage of improvement). Operation : One side of the affected area will be randomly assigned to fractional CO2 laser every four weeks for three months. The other side will be assigned to Q-switched Nd:YAG laser every four weeks for three months. Method of randomization: Using closed envelopes containing cards with fractional CO2 Rt and fractional CO2 Lt and the patient will draw one of them blindly. The assessment will be done by blinded investigator. Post-operative: Patients will be instructed to avoid sun exposure for one week after the session and regular use of sun block in between sessions.
Each side of the neck pseudo acanthosis nigricans was randomized in to either receiving glycolic acid peel or saline. Evaluation was done at baseline and after 3 sessions 2 weeks apart by percentage involvement and by ANASI score
Effect of Melatonin on Body Composition, Glucose Metabolism and Lipid Metabolism.
Obesity is often accompanied by insulin resistance and/or hyperinsulinemia. Acanthosis nigricans (AN) is a skin condition commonly present on the neck of obese children. Metformin is a useful drug for conditions characterized by insulin resistance.The aim of this study is to compare the efficacy of metformin versus placebo on AN lesions of the neck as well as their effects on metabolic and anthropometric variables in a sample of obese children. This is a 12-week randomized, double-blind randomized trial involving obese children with AN to receive either metformin or placebo. Evaluations will be performed every three weeks. Clinical, histological and colorimetric assessments of AN lesions will be compared initially and at the conclusion of the study.
The goal is to build social/cultural, political/economic, and physical/built environments that will promote active play and intake of healthy food to prevent young child obesity in the Pacific Region. Our methods will support local culture in order to achieve this goal in these remote, underserved native populations. CHL will engage the community, and focus on capacity building and sustainable environmental change. The focus of the CHL community-based program is to promote healthy eating and to increase physical activity. In order to demonstrate effectiveness, the investigators will recruit and measure children in six communities selected in each of our jurisdictions in the Pacific. These represent intervention communities, comparison communities, and temporal communities.
