This is a double-blind, randomized, placebo-controlled, proof of concept, study in adults with poorly controlled moderate to severe asthma. The researchers believe that by using a local anesthetic to block a certain nerve in the ear, it will improve all aspects of asthma, such as decreasing the numbers of times patients have to use a rescue inhaler, and improving asthma treatment assessment questionnaire scores, with no bad changes to lung function and inflammation.
A prospective, double blinded, multi-center study to assess the validity and clinical utility of the pre-operative NOCISCAN-LS software in the identification of painful lumbar discs, and the correlation with improved surgical outcomes at 3, 6, 12 and 24 months (follow-up) following spine surgery in a single enrollment arm of subjects with chronic symptomatic single level degenerative disc disease (DDD) at L3 to S1, but with two evaluation groups- Match Group and Miss Group,of subjects based on the association between the NOCISCORE results of treated and untreated disc levels.
This study will assess whether more frequent measurement of patient reported outcome measures (PROMs) - specifically health related quality of life (HRQL) - can improve the evaluation of the clinical effectiveness and cost-effectiveness of catheter ablation of ventricular tachycardia (VT) in patients with an Implantable Cardioverter Defibrillator (ICD). It is designed to have feasibility outcomes which contribute to answering the above.
Obesity remains a major public health challenge. Intermittent fasting continues to gain popularity compared to continuous energy restriction as a weight-loss approach for cardiometabolic health. Studies to date comparing intermittent energy restriction (IER) and continuous energy restriction (CER) have not been investigated on weight loss and cardiometabolic risk markers in low-income countries like Nepal. The main objective of this study is to compare the effectiveness of IER versus CER diet on weight loss and cardiometabolic risk markers over the course of six months among overweight/obese Nepalese population. This study will adopt a parallel arm, open-label, randomized control trial design. The study duration will be six months from baseline to endline. A total of 112 overweight and obese participants, aged 18-64 years, with waist circumference >90 cm (men) and >80 cm (women) will be enrolled in the study. Interested participants will be approached through social media and consecutively enrolled and assigned to either IER group (n=56) or CER group (n=56) randomly. Participants will be provided Mediterranean pattern dietary intervention including two groups: IER group will receive 5:2 diet pattern (5 day without energy restriction and 2 days with 75% energy restriction, net weekly energy deficit ~25%), and CER group with a low-calorie diet (daily energy deficit ~25%) over the course of six months. Both IER and CER group will be provided personalized diet plan, portion size, nutrition counseling focus on dietary guidance, motivational strategies, and personal goal setting for behavior change with educational materials. Baseline data will be collected using a structured questionnaire and the biochemical tests will be done. Baseline data will be collected at the time of enrollment, midline in three months, and end-line data collection in six months. The primary outcome of this study will be the change in weight loss between IER and CER groups. The secondary outcome measure will be to evaluate changes in nutritional composition, eating behavior, and cardiometabolic risk markers between IER and CER group over six months. Data will be entered using Epidata Software and transferred to the Stata/MP version 14.1 for further analysis. Data will be analyzed using an intention-to-treat basis. Independent t-test and, repeated measures ANOVA will be used to estimate changes between-group comparisons. The significance level will be assumed at p<0.05
The general purpose of this study is to examine whether the dual mobility cup (Novae® Serf) reduces the number of hip dislocations after total hip replacement, both early dislocation (≤1 year) and late dislocation (>1 year) after primary THR compared with a conventional cup design (Trabecular MetalTM Modular Acetabular System).
1- Determine the efficacy and safety of concurrent capecitabine and external beam irradiation in patients with early stages breast cancer.
Diquafosol ophthalmic solution (DQS) stimulates P2Y2 receptors on the ocular surface, which enhances mucin secretion from goblet cells. Therefore, tear film stability and hydration of the ocular surface can be achieved independent from lacrimal glands function. This prospective, open label pilot study will include 140 eyes of 70 diabetic patients diagnosed with DED and will be consecutively assigned to DQS (n=140 eyes). Participants in the DQS group will receive 3% Diquafosol ophthalmic solution. The dosage of 3% Diquafosol will be one drop, six times per day for 4 weeks. Tear film lipid layer (TFLL), non-invasive breakup time (NITBUT), corneoconjunctival staining score (CS), meibum gland (MG), conjunctival hyperemia (RS score), ocular surface disease index (OSDI) will be assessed and compared at baseline, day-14, and day-28.
Gastric cancer is the fifth most common malignancy in the world after cancers of the lung, breast, colorectum, and prostate. Gastric cancer is the third leading cause of cancer death and is responsible for 723,000 deaths yearly. Gastric carcinoma (GC) is a multifactorial disease which is difficult to diagnose in early-stage because of a time lag between the onset of growth and the appearance of clinical presentation. So, its prognosis is poor as evidenced by the 5-year survival rate. Klotho is anti-aging gene encoding a protein with multiple pleiotropic effect. Cancer and ageing share comparable principles. Klotho gene has been described as a tumor suppressor gene in numerous solid tumors and hematological malignancies. Klotho expression has been shown to be significantly down-regulated in malignant tissue compared to adjacent non-malignant tissue with good prognosis in cancers with high Klotho expression, including colorectal, pancreatic, gastric, esophageal, breast, hepatocellular, ovarian, and renal carcinomas. In contrast, a recent study documented that Klotho negative invasive duct carcinoma group exhibited good prognosis than the Klotho positive group regarding the disease- free survival after the surgical resection in breast cancer patient. Lipoprotein receptor- related protein 6 (LRP6) is a type I single transmembrane protein which is a member of the low-density lipoprotein receptor (LDLR) gene family of receptors that is highly conserved among species. In 2000, LRP6 was identified as a co-receptor for Wnt and Frizzled (FZD) to transduce Wnt/β-catenin signaling. Dysregulation of LRP6 is involved in cancer. LRP6 is highly expressed in several cancer cell lines and overexpression of LRP6 promotes cancer cell proliferation. LRP6 expression is frequently upregulated in breast cancer tissue, and respective overexpression or knockdown of LRP6 induces or inhibits breast tumorigenesis. LRP6 is highly expressed in tumors of liver cancer patients, and overexpression of LRP6 promotes liver cancer cell proliferation and tumor growth. In prostate cancer, high expression levels of LRP6 are detected which activate Wnt/β-catenin signaling and glycolysis through Akt signaling. The end result is increased prostate cancer cell proliferation. The mechanism of Klotho-mediated Wnt inhibition was as a result of Klotho binding to Wnt ligands, namely Wnt3A and Wnt5A; thereby impeding binding of these ligands to their cell surface receptor.
A two stage phase 2 study with an interim analysis to provide evidence that subjects provided with early administration of NanO2 who are located at small rural spoke hospitals and identified with large vessel occlusion ischemic strokes as well as viable penumbra prior to transfer to larger hub hospitals and who continue dosing NanO2 until revascularization is achieved by intravenous alteplase and/or mechanical thrombectomy, will experience stroke recovery by shifting ischemic brain tissue to normal tissue pO2 environments.
Cost-of-illness studies in palliative care (PC) are a growing area of interest in health economics activity. They are, in part, stakeholders' basis for deciding the allocation of the scarce public and private economic resources. There is no standard methodology to capture the formal and informal costs and expenses that health services and patients and their caregivers make during the PC attention period due to non-standard health services, and data capture approaches.
