Filter by:There are indications that phosphatidic acid (PA) supplementation is capable of enhancing gains in strength and muscle mass in response to strength training, although the literature is still incipient and controversial. Given the possible benefits in terms of maintenance and increased skeletal muscle mass, which still need confirmation, this study aims to examine the effectiveness of PA supplementation in two different doses in increasing skeletal muscle mass and strength in adult men undergoing to 8 weeks of strength training. For this, about 45 men will be randomly allocated to one of three treatments at a ratio of 1:1:1: PA 750mg per day, PA 375mg per day, or placebo (cornstarch, 750mg per day). All participants will undergo a 8-week strength training program, 3 times a week, totaling 24 sessions, which will begin with the start of supplementation. Individuals will be assessed for maximum dynamic strength of upper and lower limbs, resistance to dynamic strength of upper and lower limbs, body composition, muscle cross-sectional area and food consumption. Samples of venous blood will also be collected to determine the concentration of creatine kinase (CK), lactate dehydrogenase (LDH), testosterone, insulin-like growth factor type 1 (IGF-1), growth hormone (GH) and cortisol. These evaluations will be carried out before (PRE) and after (POST) the period of supplementation and training. Additional blood samples will be taken 48 hours after the first and last training sessions, for specific determination of blood muscle damage markers: CK and LDH.
Left ventricular hypertrophy (LVH) is the most common result of the heart trying to pump blood against the high afterload, as in hypertension and aortic stenosis.Although hypertension is the most common cause of LVH, LVH can also be found in athletes and cardiomyopathies or in storage disorders such as amyloidosis. In addition, genetic diseases also play an important role in the pathogenesis of LVH. Fabry disease is another disease that should be considered in patients with left ventricular hypertrophy.Left ventricular hypertrophy is a common and potentially modifiable cardiovascular risk factor that is frequently overlooked in clinical practice.The benefit of combining ECG and echocardiography in the diagnosis of LVH has been demonstrated.Early diagnosis and treatment-related regression of LVH, reduces adverse cardiovascular events and improves survival.Therefore, the investigators planned to perform a retrospective, observational LVH-TR study in order to determine the etiologic causes of LVH, the symptoms presented by the patients, and the effects of patients' demographic characteristics on LVH.
Perioperative management may have strong connections with postoperative complications (PCs). However, little is known about the perioperative risk factors of PCs after septal myectomy in hypertrophic obstructive cardiomyopathy (HOCM) patients. This study is designed to assess the in-hospital PCs rate of HOCM patients and to identify perioperative risk factors of PCs in patients who underwent septal myectomy. Retrospective chart review will identify adult HOCM patients who underwent septal myectomy from October 2013 to December 2018 in the investigators' hospital. Patients' data will be collected from electronic medical records. The multivariable logistic regression analysis will be used to determine independent predictors. The predictive ability of individual predictor and different combination of multiple risk factors on PCs will also be calculated.
The DZHK TranslatiOnal Registry for CardiomyopatHies (DZHK TORCH) represents a unique resource of clinical data and high quality biological samples to enable innovative clinical and molecular studies on cardiomyopathies (CMP). As a multi-center German cardiomyopathy registry, TORCH has been prospectively admitting patients since December 2014. 2,300 patients were recruited as planned. Taken together, patient data showed that the prevalence of these diseases is much higher in men than in women, atrial fibrillation is common in all forms of CMPs as well as rare forms of disease indicate a higher risk and higher morbidity. This DZHK TORCH register is now to be expanded with a second phase (DZHK TORCH-Plus). The second phase DZHK TORCH-Plus consists of 4 main modules: 1. "Clinical phenotyping, follow-up & biosampling" 2. "Genomics", 3. "Inflammation" and 4. "Biomarker". The central aims are 1) to significantly increase the number of probands (n = 4340) in order to better address the different types of CMPs, especially patients with rare CMP forms such as LVNC and ARVC or with probably molecularly explainable cardiomyopathies (familial DCM), 2) to prolong the longitudinal with a further follow-up to achieve sufficient events and thereby derive clinical recommendations for risk assessment, 3) to increase the number of probands with state-of-the-art phenotyping, 4) to pinpoint the effect of myocardial inflammation, fibrosis, gender and to determine or predict genotypes based for outcome, 5) to validate novel biomarkers developed in other DZHK studies, and 6) to foster active cooperation with international CMP registries and partners from industry.
This study aimed to detect tongue swelling induced by the pressure exerted by tongue depressor; swelling detection was made through tongue surface area measurement using ultrasonography (USG) in pediatric patients who underwent adenoidectomy surgeries.
Skeletal muscle mass is regulated by the balance of muscle protein synthesis (MPS) and muscle protein breakdown (MPB). MPS is sensitive to exogenous stimuli, particularly exercise and protein ingestion. Much of what the investigators currently know about the impact of exercise and protein feeding on MPS has been derived from acute stable isotopic tracers in a controlled laboratory setting. However, recently, the field of skeletal muscle protein metabolism has moved towards the use of deuterium oxide (deuterated water (D2O)) to measure MPS. The ease of administration and the scope to measure turnover in a range of substrates whilst negating the need for strictly controlled laboratory settings makes D2O the ideal candidate to provide a more holistic view of in vivo skeletal muscle metabolism.
The study is a prospective, randomized, controlled, intra-person split-face trial with blinded evaluations. The objective is to compare efficacy and adverse effects of ablative fractional CO2 laser resurfacing versus radio-frequency microneedling for treatment of atrophic acne scars in the facial area. Two comparable areas with acne scars on each side of the face are treated. One area will be treated with fractional CO2 laser and the other area with radio-frequency microneedling. Outcome measures will be assessed by blinded investigators and included subjects at baseline before treatment and at follow-up visits 2-4 days and 1 and 3 months post-treatment. On-site assessment and OCT will be performed at the time of the visits. OCT scans will be offered to the subjects and are optional. Clinical photos are used for documentation. 15 participants will be recruited. The participants will be recruited to enter the trial in the clinic by investigators at the Department of Dermatology, Bispebjerg Hospital, and must meet the inclusion criteria (at least 18 years of age, acne scars in the facial area, comparable atrophic acne scars on each side of the face, fitzpatrick skintype I-III) to be eligible to enter the study. No personal remuneration will be awarded the investigators. None of the collaborators have any personal economic interest in the study. Participants will not receive remuneration. All treatments are performed at the Department of Bispebjerg Hospital and patients are covered by the Hospital's patient insurance. The declaration of Helsinki will be respected as well as the standards of good clinical research. Respect for privacy as well as physically and mentally integrity of the participants will be maintained. The study will be performed in accordance with Danish Health care authorities.
Executive Summary Hypertrophic scars are irregular, raised scars that can cause debilitating symptoms including pain, pruritus, and restricted movement in nearby joints. There are also often significant psychosocial elements with these scars that are especially significant in the vulnerable pediatric population and their parents. Current scar treatment modalities are limited. In recent years, the advent of ablative fractional laser (AFL) resurfacing technology has shown great promise but there remains a need to expand high-level evidence and develop optimal laser treatment parameters for patients. In this study, the investigators aim to evaluate the efficacy of ablative fractional CO2 laser treatment of hypertrophic scars in children and define a set of laser treatment parameters to develop a treatment protocol that maximizes the safety and efficacy of AFL therapy in the pediatric population. This will be a prospective split-scar clinical trial at Alberta Children's Hospital. A sample size of 44 scars will be sufficient to detect a clinically significant improvement in total POSAS score, our primary outcome measure. Children (age 1- 17) who present with hypertrophic scarring following an acute injury or burn may be included in the study. All patients will receive standard scar treatment modalities and will be followed by our plastic surgery team and rehabilitation team. Each scar being studied will be split into two halves which will be assigned a unique "Site ID" that will be recorded in a data collection sheet and used to identify scars for assessment. All laser treatments will be performed by a single surgeon using the UltraPulse CO2 Laser (Lumenis, Israel) and will be done at the Alberta Children's Hospital in the main operating room under a general anesthetic. Patients will receive laser treatments at 4 to 8-week intervals for a total of 3 sessions. A combination of the SCAAR FX and Deep FX treatment modes, with or without Active FX treatment mode, will be used according to individual patient and scar characteristics. Data collection includes demographic data and original burn data. Assessment tools including the POSAS and SCAR-Q questionnaires, clinical photographs, and cutometer will be used at various time points to document changes in scar appearance and pathology over the study period. Mean values for the cutometer measurements as well as the POSAS and SCAR-Q questionnaires will be compared between laser-treated and control scar sites. Each of these datasets will be tested for normality using the Shapiro-Wilk test. Non-parametric data will be compared using Wilcoxon signed-rank test and parametric data will be compared using Student's t-tests.
Hypertrophic cardiomyopathy (HCM) is the most common inherited heart disease. A relatively common subgroup of HCM patients have apical HCM - a type of heart muscle disease that causes abnormal muscle thickening towards the tip (apex) of the heart. This can impair the heart's own blood flow through the thickened heart muscle. We think this is one of the causes for symptoms such as shortness of breath and chest pain. If medications are ineffective at treating symptoms, there are few further options available, limited to invasive heart surgery. This study aims to determine if it is possible to improve the blood flow within by altering the settings of patients' permanent pacemakers, dynamic microvascular obstruction is an important cause of perfusion abnormalities in HCM and whether introducing localized dyssynchrony with ventricular pacing improves this. This phased study will include patients with apical HCM that already have implanted pacemaker devices to remove risks associated with device implantation. The study may provide insights into novel mechanisms for symptoms in HCM and provide new methods for treating a patient group in whom therapeutic options can be extremely limited.
Patients with HOCM and severe LVOT obstruction can remain asymptomatic while significant cellular and structural changes of the heart (adverse remodeling) may occur preceding heart failure and rhythm disorders. Hence, preventing adverse remodeling through LVOT desobstruction may have significant impact on cardiac function and geometry in this particular population, as it is in symptomatic patients. The investigators will assess functional and structural characteristics of the myocardium in asymptomatic vs. symptomatic patients with severe LVOT obstruction before and after PTSMA, using advanced imaging studies with LGE-CMR and echocardiography.
