Filter by:This research is created for compare the difference of AHI variation between LSG and combined surgery on obstructive sleep apnea in obese patients , evaluate the risk of combined surgery and explore the correlative factor of the curative effect.
The definitions for R0 and R1 margin status after resection for pancreatic cancer are controversial.Various studies showed the rate of noncurative resections of 15- 35 % but with modified pathological examination (R1/R2) revealed the rate of R1 resection was higher ranging from 76-85 % . Verbeke CS etal. - Whether this discrepancy was caused by incomplete lymphnode dissection, perineural dissection and improper pathological examination was not yet known. - Perineural invasion was detected in 77 % of specimens of resected pancreatic cancers. So the researchers emphasized the need of new surgical classification involving mesopancreas. It can be considered as an anatomical space bounded anteriorly by the the posterior surface of the pancreatic neck, posteriorly by the pancreaticoduodenal coalescence fascia, medially by the mesenteric vessels with -nerves, lymphatics and vessels as its contents.
OBJECTIVE: To gain mechanistic insights, we will compare effects of low fermentable oligosaccharides, disaccharides and monosaccharides and polyols (FODMAP) and high FODMAP diets on symptoms and colonic protease expression in patients with diarrhea predominant irritable bowel syndrome (IBS-D). We will measure how protease changes affect excitability of pain sensing neurons and correlate this with measurements of the metabolome and the microbiome. DESIGN: We aim to perform a single blind prospective study of patients with diarrhea predominant IBS (Rome IV criteria) who will sequentially consume a high and low FODMAP diets, each for 3 weeks. Symptoms will be assessed using the IBS symptom severity scoring (IBS-SSS). Electrophysiological studies of changes in mouse dorsal root ganglia neurons in response to colonic mucosal/lamina propria supernatants will be carried out. Protease antagonist will be used to specifically assess protease expression. The metabolome will be evaluated using metabolic profiling in urine using mass spectrometry. Stool microbiota composition will be analysed by 16S rRNA gene profiling. All the above testing will be performed at 4 time points: at baseline, 3 weeks following a run-in period, after a 3-week-long high FODMAP diet, and after a 3-week-long low FODMAP diet period. HYPOTHESIS: We anticipate that colonic tissue protease effects on the excitability of dorsal root ganglia (DRG) neurons will increase with a high FODMAP diet and decrease with a low FODMAP diet, but that this may not be found in all patients. The magnitude of the effect may vary and this variation could be due to differences in the individual patients microbiome.
The traditional method of choice for intravesical resection of bladder tumors is conventional transurethral resection of bladder tumor (cTURBT). However, there has long been an ambition to overcome its biggest limitation, tumor fragmentation. Possible consequences include cell seeding and poor specimen quality, including missing detrusor muscle, thermal tissue damage, and tissue fragmentation. En bloc resection of bladder tumor (ERBT) represents an alternative technique for resection of bladder tumors. There is no doubt that ERBT has huge potential. ERBT provides specimens of high quality that are easy for pathologists to read. In theory, this may sustainably change the view on secondary resection, lead to faster decisions on subsequent treatments, and influence patient prognosis. Thus, there is an urgent need to compare ERBT with cTURBT in a thoroughly planned trial.
Soft tissue biotype is a critical factor for success of implant in the esthetic zone . Different soft tissue augmentation techniques have been employed to increase soft tissue thickness such as: autogenous grafts, allografts, xenografts and living cellular construct (LCC). Studies showed that, allografts and xenografts were inferior when compared with autogenous graft . However, few studies were conducted to evaluate the efficacy of soft tissue augmentation with platelet rich fibrin in order to overcome the patient morbidity with SCTG.
Nephrotic syndrome (NS) is among the most common pediatric kidney diseases and is defined as massive proteinuria (>40 mg/m2/h or urine protein to creatinine ratio >2 g/g) leading to hypoalbuminemia (<2.5 g/dL), edema, and hyperlipidemia. 60-70 % of patients present prior to age of 6 years
The aim of the study is to assess arch dimensions among children with surgically repaired unilateral cleft lip and palate.
The intent of this study is to see how boys and girls aged 1-5 and coughing since 1-2 days due to common cold respond to a specific protective cough syrup taken before going to bed for one night, with respect to a similar but not specific syrup (placebo). The symptoms evaluated include especially cough frequency but also cough intensity, bother, and sleep quality of the child and parents.
This is a randomized clinical study. 48 subjects with a confirmed diagnosis of deep carious molars without pulpal lesions were randomized to one of two treatments: Patients treated with Light-cured calcium silicate (Theracal) liner, or treated with light-cured calcium Hydroxide (Biner LC) liner. Both two Treatments are with the step-wise excavation Technique. Treatment will be done at baseline, collecting dentin sample before application of liner material, then patients will be dismissed with Resin-modified Glass Ionomer restoration and recalled after 6 months. Re-entry of tooth required for completing the step-wise excavation technique collecting the second dentin sample after this time interval (6 months) and permanently restore tooth with composite restoration. Dentin samples will be microbiologically analyzed and the results will be statistically calculated.
Effect of high calorie high protein diet versus high calorie,glomerular filtration rate (GFR) based protein intake in non-obese advanced HF patients will be assessed. In this regard, protein intake impact will be measured on muscle mass, physical performance and renal function as main outcome. Rehospitalization, quality of life, depression an inflammatory status are second endpoints.
