The obesity epidemic calls for new therapeutic opportunities to prevent and treat obesity and its comorbidities amongst which are insulin resistance and cardiovascular diseases. Recent evidence suggests that tissue oxygenation plays an important role in cardiometabolic health. Remarkably, individuals residing at high altitude (hypobaric hypoxia) are less prone to develop type 2 diabetes mellitus as compared to individuals living at sea-level (normobaric normoxia). Furthermore, there is evidence to suggest that normobaric hypoxia exposure may improve glucose homeostasis and insulin sensitivity in both rodents and humans. The level of physical activity is an important determinant of insulin sensitivity and glucose homeostasis. It is well established that performing physical activity improves glucose uptake in the short term, and glycemic control in the long term. Interestingly, recent studies have demonstrated that an acute bout of exercise under hypoxic conditions (inhalation of air containing less oxygen) may lead to a more pronounced improvement in plasma glucose concentrations and/or insulin sensitivity as compared to normoxic exercise. However, the effects of repeated hypoxic exercise bouts on glucose profile throughout the day (i.e. 24h continuous glucose monitoring) remain elusive. In the present randomized, placebo-controlled, single-blind, cross-over study study, the investigators will investigate the effects of exercise under mild normobaric hypoxic conditions (FiO2, 15%) for 4 consecutive days (2 x 30-min cycling session at 50% WMAX) on postprandial substrate metabolism and 24h-glucose level in overweight/obese subjects with impaired glucose tolerance. The investigators hypothesize that 4 consecutive days of exposure to mild hypoxia while performing moderate intensity exercise improves glucose homeostasis in overweight and obese individuals with impaired glucose homeostasis.
This is a prospective randomized trial comparing two prostaglandin E2 (dinoprostone) agents used for labor induction in pregnant women with term pregnancies and unfavorable cervix.
This prospective study will assess if 12 months of vitamin D3 (cholecalciferol) supplementation, in patients with AAV (GPA, MPA, and EGPA) who have deficient or insufficient 25(OH)D3 status at enrollment, correlates with improved disease activity and/or lower frequency of relapse (compared to historical data and a previously conducted cross sectional study (part I) that assessed vitamin D status in a cohort of similar patients).
The overall objective of this project is to investigate the effectiveness of Acute Intermittent Hypoxia (AIH), to improve muscle strength and activity level in individuals with relapsing-remitting MS.
Atrial fibrillation (AF) is a condition detected as an irregular heartbeat. It is the most common rhythm disturbance worldwide which can lead to significant symptoms and serious health problems (stroke and heart failure). The longer a person has AF, the more difficult it is to restore a normal heart rhythm. Those with continuous AF for longer than a year are described as having longstanding persistent AF (LSPAF). This is the most challenging type of AF to treat and medications are often not effective. Apart from medications patients with LSPAF may be offered a medical procedure to help improve their symptoms. It involves putting a flexible thin tube (catheter) into a blood vessel in the groin and up into the heart to destroy the tissue causing irregular heart beat. This procedure has modest success in improving symptoms in the long term. Recently, keyhole surgery has been used for these patients and evidence shows that it is better than the catheter procedure. However, we do not know how well people are doing beyond one year. Feedback from a patient focus group suggested that knowing the long-term results of these two procedures is important to help them make an informed choice when it comes to treatment. In this study we propose to continue monitoring patients from a randomised clinical trial (CASA AF RCT) who have already had one of the procedures. They have a small heartbeat monitor implanted under the skin with a battery life of around 3 years. We will be able to look at their heart rhythm data for the duration of this period and detect the return of the fibrillation if it happens.
This study was conducted to determine the effectiveness of MBI technique in reducing the stress level of anesthesiology and intensive therapy residents at the Faculty of Medicine, University of Indonesia.
Adequate shaping and cleaning, followed by a good coronal seal, are prerequisites for a favorable outcome. The goal of root canal preparation is to create optimized canal geometry to allow effective irrigation and obturation with preservation of the original canal morphology. The aim of current study is to evaluate the effectiveness of Fanta and Zunba rotatory instruments in cleaning of infected root canal of primary molars to those instrumented with manual K-files.
The trial aims to verify a possible greater analgesic efficacy of PENG (Pericapsular Nerve Group) block compared to iliac fascia block (FIB block) in elderly patients (age > 65 years) suffering from traumatic fracture of proximal femur in emergency room.
A randomized controlled trial will examine mindfulness-based relapse prevention (MBRP) program outcomes for 240 individuals who have completed treatment for opioid or alcohol use disorders. MBRP is a group aftercare program that integrates mindfulness skills training with cognitive-behavioral relapse prevention strategies. Primary outcomes will include frequency of opioid/alcohol use, craving, withdrawal, and quality of life. Secondary outcomes include time to first opioid/alcohol use, adherence to medication-assisted treatment plans, perceived stress, posttraumatic stress symptoms, and chronic pain. We will also examine the following potential moderators of intervention outcomes: comorbid diagnoses, life events history, and MBRP intervention adherence. In addition, we will examine the following mediators of intervention outcome: mindfulness skills, emotion regulation skills, executive functioning skills, savoring, and positive and negative affect.
