The purpose of this study is to determine if additional panretinal photocoagulation of ischemic areas following retinal vein occlusion (RVO) may reduce the rate of recurrence and allow longer treatment intervals in anti-Vascular Endothelial Growth Factor (VEGF) treatment following the "trea-and-extend" scheme.
The purpose of this study is to identify the effects of family work shop for children with developmental delays.
Countless studies are performed to quantify the severity of heart disease and its influence on the respiratory system, checking that their heart conditions and the surgical process determine pulmonary complications, one of the most common causes of morbidity and mortality in the postoperative period of cardiac surgery . After surgical procedures, there is a reduction of the residual volume (RV), total lung capacity (TLC), vital capacity (VC) and functional residual capacity (FRC), leading to the formation of atelectasis, with alterations in the ventilation-perfusion ( V / Q), the partial pressure of carbon dioxide in arterial blood (PaCO2) and partial pressure of oxygen in arterial blood (PaO 2). Pulmonary function is impaired in the postoperative period of cardiac surgery, due to various factors common to this major surgery that will drive the patient to develop respiratory complications such as atelectasis and pneumonia. Physical therapy plays an important role in the treatment of patients undergoing cardiac surgery, both in the preoperative period and postoperative, in order to prevent or minimize the respiratory complications. Follow-up studies on cardiac rehabilitation quantify the quality of all the activities necessary to ensure to patients with heart disease patients the best physical , mental and social conditions so that consequently they are able , with its effort to regain a normal position in the community and lead a active and productive life over time, therefore, the clinical changes resulting from an extensive cardiac surgery are already highly dedicated described in literature but which daily life factors or rehabilitation interventions that the patient will take in the late postoperative period that really assisted in his complete recovery and inclusion into society they are still not well elucidated , so it is appropriate to carry out this project due to the fact exposed to up. The project to be developed whose main justification clarify issues related to the return or preservation of the individual feature that undergoes extensive cardiac procedure , as well as incidence of mortality after 12 months of the procedure. The current literature does not expressed clearly, possible impacts on functionality and return the daily activities of the individual in the late postoperative period , since such malfunctions in the immediate post operative period are already fully understood.
This is an observational prospective study. Patients diagnosed with advanced epithelial ovarian cancer (stage IC or higher) since 2008 will be asked to participate in this study by signing an informed consent. Tumour samples will be reviewed to confirm the diagnosis and to select the best regions for tissue sampling to perform the following molecular studies: array-based Comparative Genomic Hybridization and Next Generation Sequencing. Detected mutations will be analysed by Sanger sequencing. FISH probes will be designed and tested on the samples.
The purpose of this study is to evaluate the efficacy and safety of Apatinib combined with S-1 as first-line therapy for patients with advanced gastric or gastroesophageal junction adenocarcinoma.
The main objective of this study is to investigate the role of female sex hormones in relation to insulin resistance in a controlled human experimental model of menopause and to explore whether exercise and/or hormone treatment (HT) can compensate for loss of endogenous sex hormone production by maintaining insulin sensitivity and metabolic activity at a level equivalent to what is seen in premenopausal women. Loss of ovarian function is associated with an increased incidence of metabolic disease including metabolic syndrome, type 2 diabetes and cardiovascular disease. This increased disease incidence seems to be related to changes in body composition including decreased skeletal muscle mass and increased visceral fat mass as well as decreased whole body fat oxidation and energy expenditure. Regular physical activity decreases general mortality among other things by increasing fat free mass and insulin sensitivity and hereby prevents metabolic syndrome and cardiovascular disease - conditions seen with an increased incidence after menopause and could therefore be a possible treatment. In the present study the Investigators will assess the role of sex hormones in a model of menopause where healthy women are undergoing planned bilateral oophorectomy due to risk of hereditary ovary cancer. The use of this model makes it possible to control the time point for loss of ovarian function and hereby investigate the timeframe and possible contributing factors in a strictly controlled model. 48 premenopausal women will be included in the study. The study is conducted in women who have already been offered surgical oophorectomy. The first 2 months the study will be an observational cohort study. Hereafter the patients will be allocated to one of four groups (n=12) in a randomized controlled trial, addressing the effects of 6 months of exercise with or without HT. Type of surgery has been decided before inclusion based on medical indications. The women will be offered HT according to national guidelines, but the choice is up to them. Randomization applies only to the training intervention. Firstly the Investigators aim at investigating the role of endogenous female sex hormones and HT in relation to insulin resistance, whole body fat oxidation and -energy expenditure, changes in visceral fat mass and fat free mass after oophorectomy. Secondly, the Investigators wish to study the molecular mechanisms behind the oophorectomy-induced insulin resistance with a focus on insulin signaling in skeletal muscle and fat tissue. Lastly, the investigators aim to explore whether exercise and/or HT can compensate for loss of endogenous female sex hormone production by maintaining IS and metabolic activity, hereby preventing future incidents of metabolic disease in relation to menopause. All in all, this project will contribute with new knowledge concerning the question of how endogenous female sex hormones affect insulin sensitivity and metabolic functioning and how exercise may be used as a disease preventive modality for middle-aged women.
Low level laser therapy (LLLT) was shown to affect muscle performance and fatigue. The aim of this study is to investigated the effect of B-cure laser on muscle performance and recovery after intense exercise.
Very large bile duct stones are difficult to remove. Dilation-assisted stone extraction, also termed small endoscopic sphincterotomy plus endoscopic papillary large balloon dilatation, is safe and effective technique for the treatment of large CBD stones. However, in approximately 5-10% of patients, the removal of large bile duct stones may be difficult. For this selected group of patients for whom all conventional endoscopic stone treatment devices have failed, laser lithotripsy technology has provided an approach to the fragmentation of difficult bile duct stones. A single-operator cholangioscopy (SOC) system (SpyGlass Direct Visualization System, Boston Scientific Corp., Natick, MA, USA) has overcome most of the conventional cholangioscopy limitations. The investigators aimed to evaluate the efficacy and safety of Spyglass-guided laser lithotripsy for difficult CBD stones not amenable to conventional dilation-assisted stone extraction therapy.
Nasopharyngeal carcinoma (NPC) is usually treated with chemoradiotherapy. While the effects of this treatment on cochlear function is well characterized, its effect on vestibular function is not well studied. In this study the investigators will study the vestibular function of 50 patients undergoing chemoradiotherapy for NPC both before and after treatment in order to better define its effects. All patients will undergo a validated questionnaire (dizziness handicap index), posturography, audiometry and vestibular-evoked myogenic potentials.
The investigators propose a study to compare two methods of closing the stump of the appendix during an emergency excision of the appendix using a keyhole approach. One similarly designed study has been undertaken in another institution but there were not enough patients recruited to the study to allow meaningful conclusions to be drawn. Any patient over the age of 16 years whom the investigators suspect to have acute appendicitis will be considered for recruitment to the study. During their exploratory keyhole surgery, if the surgical team feels that excision of the appendix is indicated then the patient will be randomly allocated to either polymer clips or endoloops to the part of the procedure where the stump (base) of the appendix is closed. The main aim is to determine if polymer clips shorten the duration of the operation. The investigators will also determine if there is a difference between the rates of complications, the time spent in hospital and the number of times the participants had to be readmitted to hospital within 30 days.
