Filter by:The coprecipitation method was used to prepare hydroxypropyl-beta-cyclodextrin complexed with insulin (HPβCD-I) by mixing insulin with hydroxypropyl-beta-cyclodextrin (HPβCD) in the molar ratio of 1:5 with the addition of 10 mL of purified water for every 100 mg of the complex. After complete dissolution of the material, the mixture was stirred for 30 min at room temperature (25°C), then left to rest for 60 min and lyophilized. The gel was prepared by dispersing the Carbopol 940® polymer in a known amount of purified water. Under mild heating the methylparaben (0.02%, w/v), propylparaben (0.01%, w/v) and propylene glycol were dissolved and incorporated in the dispersion of Carbopol 940® and left to rest for a period of 12h. After this time, the prepared gel was stirred and pH corrected to a range of 5.0 to 7.0 with triethanolamine. A set amount of insulin and the HPβCD-I complex were incorporated into the control gel for the preparation of other formulations. A randomized, double-blind, prospective clinical trial was conducted from March 2013 to April 2014 at the Hospital Universitário Regional de Maringá (HUM), Paraná, Brazil, in order to determine the safety and efficacy of gel in patients hospitalized in the Intensive Care Unit. Hyperglycemic volunteers and those with pressure ulcers other than grade II were excluded from the study. Grade II pressure ulcers were selected as they are a superficial lesion, with little tissue loss, and allow easy visualization of healing. A letter of free and informed consent was obtained. The study was conducted with each patient for a period of 15 days. The volunteers were divided equally into three groups A, B and C, with each group being formed by five volunteers (n=5). Group A was randomly selected for treatment with gel with HPβCD-I complex, group B for treatment with gel with insulin, and group C with the control gel. Blood glucose tests were performed in order to assess whether the insulin complexed or otherwise with HPβCD could cause an increase in the rate of insulin in the blood in patients, leading to hypoglycemia. An identical standardized procedure for gel placement was used for all patients. Initially, the pressure ulcer was cleaned with saline. With the aid of a paper ruler, the ulcer was measured and photographed, as the ruler included the date and the initials of the patient. After measuring, a quantity of 5 grams of gel was placed on the pressure ulcer and covered with sterile gauze and a transparent film. The curative was changed once a day during the treatment period, unless there was leakage of fluid, contamination, or signs of infection. Every three days the pressure ulcers of all patients were measured and photographed again, resulting in a total of six measurements per patient. The photos of pressure ulcers were evaluated for measurement of pressure ulcers and any kind of irritation. At the end of this stage, the properly gathered study data was interpreted using the analysis software Mobile Wound Analyzer® (MOWA). Data was evaluated by variance analysis (ANOVA), and means were compared with the Tukey test (p < 0.05) using the software Statistica 8.0/2008 (Stat Soft Inc., Tulsa, USA). Mixed model repeated measures methodology with some covariance structures was adopted for statistical analysis of the clinical trial (p < 0.05). The Statistical Analysis System (SAS) for Windows, version 9.3 (SAS Inc., Chicago, IL) program was used for statistical analysis.
Whether H2 receptor antagonist can prevent thienopyridine-related peptic ulcer remains unclear.
The purpose of this study is to evaluate the efficacy and safety of ustekinumab as intravenous (IV: into the vein) infusion in induction study in participants with moderately to severely active Ulcerative Colitis (UC) and as subcutaneous (SC) administration in maintenance study in participants with moderately to severely active Ulcerative Colitis (UC) who have demonstrated a clinical response to Induction treatment with IV ustekinumab.
The BIPPED study seeks to determine whether wound healing, in particular diabetic foot ulcers, can be monitored using electrical bioimpedance analysis (BIA). BIA measures the resistance of biological tissue to the passage of a very small electric current applied with electrodes. Different types of tissue, due to cell structure, hydration and vascularization, have specific electrical characteristics. The BIPPED study aims to provide experimental data for the development of a BIA sensor for monitoring of wound healing in chronic wounds.
The purpose of the study is to assess treatment tolerance and comfort in chronic VLUs after 4 weeks of treatment using a dual action pneumatic compression device.
This is a safety and efficacy study of LiRIS® in females with interstitial cystitis with Hunner's lesions.
This is a phase I open-label study to evaluate the safety of ALLO-ASC-DFU in diabetic foot ulcers patients. ALLO-ASC-DFU is a hydrogel sheet containing allogenic adipose-derived mesenchymal stem cells. Adipose-derived stem cells have anti-inflammatory effect and release growth factors such as vascular endothelial growth factor (VEGF) and hepatocyte growth factor (HGF), which can enhance wound healing and regeneration of new tissue, finally may provide an new option in treating a diabetic foot ulcer.
A novel method (PCT n. WO 2010/007502 A2, 2010) has been developed to obtain platelet gel from umbilical cord blood (CBPG). The main advantages so far identified in CBPG as compared to platelet gel derived from adult platelets relate to the lack of microbiological contamination in the former and to a different profile of growth factors concentrations, such as a higher content of VEGF and lower content of TGF in CBPG. Recent developments have led to a procedure in which CBPG can be prepared, stored in a cryopreservation bag and applied to the skin ulcer without breaking the sterility chain. In spite of promising results on allogeneic CBPG, a randomized clinical trial of sufficient statistical power to detect significant advantages (clinical and economical) will be performed in patients affected by diabetic foot ulcers and randomly treated with CBPG versus standard local medications (SLM).This study is a multicenter (8 centers) controlled randomized clinical trial. Outcomes: (1) primary objective is to evaluate the number of closed skin ulcers within 4 weeks of treatment with CBPG vs standard local medications; (2) secondary objectives are percent skin ulcer closure area, number and type of adverse events and cost of treatment. Sample size calculation: 95 + 5 (dropout) test and 95 + 5 (dropout) control patients ensure 80% power to detect as statistically significant (p<0.05) >60% healing in test vs 40% healing in control.Each clinical centre has been invited to enrol 15 treated and 15 control patients, according to local availability in 12 months. CB units are routinely collected after mother's informed consent before and after placenta delivery in accredited public cord blood banks belonging to the Italian Cord Blood Network (ITCBN) coordinated by the Centro Nazionale Sangue (CNS). After storage and transportation at monitored room temperature, the units will be processed for the preparation of CBPG within 48 hours of collection. CBPG will be prepared according to standard procedures with a defined final platelet concentration (0.8-1.2 x 109/L). The CBPC units will be finally cryopreserved in a -80°C freezer in view of the clinical use of the CBPG, which will require thawing at 37°C in a waterbath and activation with Calcium gluconate. For SLM, each clinical center will use their validated standard procedures.
The purpose of this study is to evaluate the efficacy and safety of Pedyphar® ointment in the healing of foot ulceration in diabetic patients.
The anticipated advantages of 3D laparoscopic visualization for the surgeon are greater accuracy and speed in manual skills, translating to decreased operative time, reduced learning curve, and superior safety.We aimed to determine the feasibility of the laparoscopic approach using 3D visualization in the surgical treatment of ulcerative colitis
