NCT04733287
Exercise tolerance decreases with age and a sedentary lifestyle. Muscle critical power (CP), is a sensitive measure of exercise tolerance that is more even more relevant to and predictive of endurance performance than VO2max. While recent evidence indicates that CP and muscle function decrease with aging, the cause of this decrease in CP and the best way to mitigate the decrease in CP are unknown. This study will: 1. Measure knee extensor CP in young and old individuals and determine the extent to which changes in muscle oxygen delivery (e.g. resistance artery function, maximum exercise blood flow), muscle mass and composition (e.g. whole-muscle size, muscle fiber cross-sectional area) and mitochondrial oxygen consumption (e.g. maximal coupled respiration of permeabilized fibers biopsied from the knee extensors) contribute to the decrease in CP with age. 2. Examine the effectiveness of two different therapies (1. High Intensity Interval Training, HIIT and 2. Muscle Heat Therapy) at improving muscle function and critical power in young and older adults. 3. Examine the impact of muscle disuse (2 weeks of leg immobilization), a potential contributor to the decrease in muscle function with aging, on muscle function and critical power and determine if heat therapy is an effective means of minimizing the impact of disuse on muscle function and critical power.

NCT02406300
This study evaluates the effect of anesthesia on mortality after surgical repair of proximal femur fracture. Patients will receive either a subarachnoid block or a combination of peripheral nerve blocks and light general anesthesia (PNB/GA). The investigators hypothesis is that a combination of peripheral nerve blocks with an opioid free light anesthesia may have more favourable outcomes. Both groups will be followed up for assessment of post-operative morbidity and mortality.

NCT04731428
This research was carried out as an pre-test/post-test control group experimental design study in order to determine the effect of progressive relaxation exercises on the level of vital sign, pain and anxiety underwent who laparoscopic surgery for colorectal cancer in patients. This research data was collected between March 2018 and May 2019. The research was carried out with 63 patients (experiment group= 31, control group= 32) who underwent elective laparoscopic colorectal surgery in a general surgery clinic of a university hospital in Istanbul and in accordance with the research criteria. Patients in the experiment group were taught breathing exercises in the preoperative period and on the 1st, 2nd and 3rd day after surgery then, progressive relaxation exercise that lasted 15 minutes was applied to the group. Pain (Short McGill Pain Scale) and anxiety (STAI-S Scale) levels of both groups were evaluated in the preoperative and postoperative period. The patient's vital signs, oxygen saturation and serum cortisol level parameters were measured in the same time interval before and after the relaxation exercise. Significance was evaluated at p \<0.05 and p\<0,001 levels in the analysis of the data. Prior to the study, the consent of the institution and ethics committee, written and verbal patient consent were obtained.

NCT04575623
Migraine is a neurological disease associated with an altered cortical excitability level . The prevalence of migraine is10.5% of adults in Assiut governorate, and is more frequent in women and in individuals with higher education level . There is evidence that migraine patients could present cognitive deficits, being the affected functions memory, processing information speed and attention. It was found that the prevalence of migraine in AlQuseir was 4.8/100 and the highest figures found during early adult life(18-40) years old .Patients with migraine found to perform significantly worse in duration pattern test(DPT),non-verbal dichotic test ,speech in noise (SPIN)test and found to have longer p300 frequency stimulus latency which indicate presence of cognitive and central auditory processing dysfunction
NCT04732741
Synucleins are a family of small, highly conserved proteins found in vertebrates and are specially abundant in neurons particularly in presynaptic terminals (Surguchov et al., 2001). Gamma-synuclein is the third member of the synuclein family, and is predominantly found in the cytosol of tumor cells and functions both intra- and extra-cellularly. It is involved in the pathogenesis of different types of cancer and some neurodegenerative diseases (Liu et al., 2018). Smoking - a major risk factor for oral cancer and its progression - and nicotine-containing products were found to time-dependently up-regulate the Gamma-synuclein expression in cancer cells (Hsu et al., 2020a). Gamma-synuclein is released from tumor cells and was found to be elevated in tumors such as urinary bladder cancer (Liu et al., 2016), colorectal cancer, gastric adenocarcinomas and esophageal cancer (Liu et al., 2012). It is present in blood, serum, cerebrospinal fluid and saliva. The detection of extracellular synucleins in body fluids can reveal the first steps of the disease thus it can be used as a potential tool for early cancer detection (Surguchov, 2016). This study aims to identify the diagnostic accuracy of Gamma-synuclein in differentiating between oral malignant lesions and oral premalignant lesions.

NCT03233984
Endocrine disruptors are known as a cancer cause. On pregnant women, it can induce major foetal pathology and impact growth. Among those molecules, bisphenol-A (BPA) is a plasticizer that can be found on cans and water. Through a prevention program, the investigators tried to warned pregnant women on endocrine disruptors exposition risks. The goal here is to assess the effectiveness of this program on their fresh products consumption.
NCT03757442
Introduction Perioperative haemodynamic instability is associated with postoperative morbidity and mortality. Macrocirculatory parameters, such as the conventionally obtained mean arterial blood pressure and cardiac output, may be uncoupled from the microcirculation during sepsis and severe blood loss and may not necessarily be optimal resuscitation parameters. The peripheral perfusion index (PPI) is derived from the pulse oximetry signal and reflects perfusion. Reduced peripheral perfusion is associated with morbidity in critically ill patients and in patients following acute surgery. We hypothesize that patients with low intraoperative PPI demonstrate high frequency of postoperative complications and mortality regardless of blood pressure. Methods and analysis We plan to conduct a prospective observational cohort study in patients undergoing acute non-cardiac surgery (November 1st, 2017 to October 31st, 2018) at two University Hospitals. Data will be collected prospectively from patient records including patient demographics, comorbidity and intraoperative hemodynamic values, with PPI as the primary exposure variable, and postoperative complications and mortality within 30 and 90 days as outcome variables. We primarily assess association between PPI and outcome in multivariate regression models. Secondly, the predictive value of PPI for outcome, using area under the receiver operating characteristics curve is assessed. Ethics and dissemination Data will be reported according to The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE). Results will be published in a peer reviewed journal. The study is approved by the regional research ethics committee, storage and management of data has been approved by the Regional Data Protection Agency, and access to medical records is approved by the hospital board of directors at the involved hospitals and departments.
