Filter by:Cancers of the upper gastro-intestinal tract, including esophagus (gullet), stomach and small bowel, are amongst the deadliest malignancies. The main reason for their high mortality rate is that they are usually diagnosed late when curative treatments are no longer effective. However, these types of cancer generally arise from well-described pre-cancerous diseases, such as Barrett's esophagus and gastric intestinal metaplasia. This provides an opportunity for clinicians to detect these pre-cancerous conditions early and offer adequate cure or clinical monitoring before they progress to cancer. A camera test (gastroscopy) is the gold-standard test to detect pre-cancerous diseases in these organs. There has been limited research to set the standards for performance of a gastroscopy, especially with regards to diagnosis of pre-cancerous conditions, which require knowledge and skills by the physician performing the test (endoscopist). Therefore, the hypothesis behind this study is that the aforementioned pre-cancerous diseases are understudied and often go undetected. This study aims to understand how often endoscopists should diagnose these pre-cancerous diseases on routine gastroscopy and help define the standards to measure performance. The investigators will assess the following rates: i. how often endoscopists diagnose these pre-cancerous lesions during endoscopy; ii. How often these conditions are diagnosed on biopsies taken according to a standardized protocol; iii. How often these condition should have been diagnosed by the endoscopists based on the review of pictures by expert endoscopists. The investigators will also compare the rates of correct diagnosis by endoscopists with different levels of experience and based on the times spent to complete the diagnostic test. Investigating these aspects will enhance the understanding of the medical community with regards to the diagnosis of these pre-cancerous lesions and set endoscopy standards to improve their early detection and treatment before they progress to cancer. This will translate to improved cancer prevention and benefit for patients.
The primary objectives of this study are: - To identify clinical or histological factors associated with gastric cancer development in patients with IM and AG - To establish a machine learning algorithm for prediction of future gastric cancer risks and individual risk stratification in patient with IM and AG
Quadriceps femoris (QF) atrophy is seen in rheumatoid arthritis and knee osteoarthritis (OA) patients. Exercise therapy is mile stone in knee OA patients also it can help thicken QF muscle of RA patients. We primarily aimed to demonstrate the influence of 4 weeks of knee isometric home-based training on QF muscle parts thickness and pennation angle measurements of RA patients with ultrasonography (USG). This study included 12 patients with RA, 12 patients with knee OA as positive control group and 13 volunteers as healthy control group. All participants were given 4 weeks of quadriceps-hamstring isometric home-based training. At baseline and at the end of the program, WOMAC and Lequesne algofunctional index scores of knee OA patients and DAS28-CRP scores of RA patients were recorded. Dominant knee thickness and pennation angle measurements of QF muscle parts were evaluated by ultrasonography.
The aim of the study is to propose a method for quantifying motor function in infants with spinal muscular atrophy treated with innovative therapies using inertial sensors.
Fractional non-ablative laser (FNAL) has been widely used in improving acne scarring. However, there was only one study reported efficacy and safety of the fractional non-ablative 1927nm thulium laser (FTL) and no studies have reported a comparison between FTL and fractional ablative 2940nm Er:YAG laser(FEL), which had been proved effective and safety in many studies. Thus, we designed a prospective, simultaneous spilt-face trial to evaluate the efficacy and safety of FTL in the treatment of acne scarring and make a comparison between FTL and FEL, hoping to provide a new available modality for patients who are intolerable or reluctant to ablative lasers.
The investigators aim to study the use of blood flow restriction therapy (BFR) to augment routine post-operative physical therapy in elderly patients (age >= 65) after recovering from surgical treatment of hip fractures.
Women over the age of 60 years have an estimated 10 to 15 % risk of recurrent urinary tract infections (UTI). This is believed to be due to hormonally induced changes in the vaginal flora associated with menopause. After menopause, there is a chemical changes in the vagina that may predispose to bacterial infections. The role of vaginal estrogen creams to restore vaginal atrophy and prevent urinary tract infections has been well characterized. Vaginal testosterone (VT) application use in postmenopausal breast cancer patients on aromatase inhibitors have been shown to improve vaginal pH, vaginal atrophy symptom scores, dyspareunia, and vaginal dryness. Although testosterone has been used to improve sexual function in postmenopausal women, the effects of VT on vaginal flora and recurrent UTIs are unknown. The purpose of this study is to determine whether topically applied vaginal testosterone cream is more effective than placebo in reducing the incidence of urinary tract infections in postmenopausal women with recurrent urinary tract infections and to ascertain the effects of topical estrogen on the vaginal pH and flora.
Alzheimer disease is hard, long and expensive to diagnose. In order to help the clinician, a new biomarker in Alzheimer disease seems to be very useful. The retina, as a window of the brain, could offer a new way to diagnose this common disease. Indeed, a retinal atrophy could especially appear in Alzheimer disease. Besides, many aspects about retinal alteration, visual function and their link with the disease deserve to be more explored. So as to fill these gaps, a new study about retinal specificity in Alzheimer disease appears to be relevant.
The purpose of this study is to investigate the effect of comprehensive swallowing rehabilitation in patients with multiple system atrophy.
To determine the effects of small and large bone graft particles vs large particles alone on percent vital bone, percent residual graft material, measured histologically from bone biopsies of the grafted site taken at the time of dental implant placement from subjects undergoing sinus augmentation for the placement of dental implants. Dental radiographs taken post operatively will be used to estimate bone graft volume differences between conditions.
