Filter by:Low mobility is a mediator for poor outcomes of hospital care. Wearable devices will be used and 2-way texting via patient smartphones to monitor patients' physical activity during hospitalization with and without gamification to improve patient adherence to existing guidance on recommended activity. After discharge, investigators will assess patient care utilization (SNF, inpatient vs home rehab, ED visits, readmission) and conduct validated surveys on patient function at 30 days after discharge.
- To evaluate different echocardiographic indices in diagnosis and follow up of group 1 pulmonary hypertension. - To evaluate blood biomarkers (troponin, uric acid and micro RNA) in naïve group 1 pulmonary hypertension.
Several studies investigating Tai Chi for hypertension have been carried out. However, investigators found the results were in high heterogeneity and poor methodological quality. Thus, investigators intend to provide high quality of the effectiveness and safety of Tai Chi for essential hypertension.
The researchers are investigating if changing an individual's behaviors may have an impact on outcomes for patients with pulmonary arterial hypertension (PAH). This research will test the efficacy of a home-based exercise program to improve exercise tolerance and physical activity.
Pulmonary Arterial Hypertension has gone from a disease that causes rapid death to a more chronic condition. Yet, improved survival is associated with major challenges for clinicians as most patients remain with poor quality of life and limited exercise capacity. The effects of exercise training on exercise capacity have been largely evaluated and showed an improvement in 6-minutes walking distance (6MWD), peak V'O2. It is also known that exercise program improves quality of life. Maximal volitional and nonvolitional strength of the quadriceps are reduced in patients with Pulmonary Arterial Hypertension and correlated to exercise capacity. Moreover, on the cellular level, alterations are observed in both the respiratory as well as the peripheral muscles. Muscle fiber size has been reported to be decreased in some studies or conversely unaltered in human and animal models. Reduction in type I fibers and a more anaerobic energy metabolism has also been reported, but not in all studies. Likewise, a loss in capillary density in quadriceps of patients with Pulmonary Arterial Hypertension and rats has been reported, but could not be confirmed in other studies. While the impact of exercise training on clinical outcomes such as exercise capacity or quality of life is well known, this data highlight the fact that the underlying causes of peripheral muscle weakness as well as the mechanisms underlying the clinical improvements observed with exercise programs are not completely understood. Improvement of muscle cell metabolism in part via the enhancement of oxidative cellular metabolism and decrease in intracellular lipid accumulation may play a role in improving muscle function and exercise capacity. In this study, we intend to evaluate the impact of a 12 weeks home-based rehabilitation program on peripheral muscle function and metabolism, focusing on lipid infiltration, oxidative metabolism and epigenetic factors that can be involved in metabolic syndrome, in patients with Pulmonary Arterial Hypertension.
Increased intracranial pressure (IICP) is a common problem in traumatic brain injuries and many medical diseases. Early recognition of IICP can save lives. Several invasive and non-invasive methods have been described for IICP diagnosis. In recent years, ultrasonographic measurement of optic nerve sheath diameter (ONSD) has become a popular method due to its high sensitivity and specificity for IICP estimation. Studies have shown that ONSD's ultrasonographic measurement correlates with the IICP and can detect intracranial hypertension. The ONSD measurement has advantages such as being easily applied by the clinician at the bedside, being non-invasive, providing immediate results, reproducibility and low cost. It is known that artificial carbon dioxide pneumoperitoneum created in laparoscopic surgeries increases intracranial pressure.However, it is not easy to estimate the degree of changes in ICP during laparoscopic surgery under general anesthesia. In the literature, there are many studies on the sonographic measurement of optic nerve sheath diameter to evaluate the effects of trendelenburg position on intracranial pressure with the use of different anesthetic drugs in laparoscopic surgeries. In addition, there are studies reporting that deep neuromuscular blockade in laparoscopic surgeries increases surgical vision and decreases analgesic requirement in postoperative period. The relationship between neuromuscular block level and intracranial pressure is not clear. From this point of view, the investigators would like to evaluate the effect of moderate and deep neuromuscular block level on intracranial pressure by sonographic measurement of optic nerve sheath diameter in laparoscopic cholecystectomy operations performed with standard pressure artificial carbon dioxide pneumoperitoneum.
This study is conducted to investigate the short-term safety and preliminary efficacy of stereotactic radiotherapy for renal denervation to treat refractory hypertension.
Non-alcoholic fatty liver disease (NAFLD) is the most frequent cause of chronic liver disease in our environment. Preliminary data suggest that portal hypertension may exist in the initial phases of NAFLD due to mechanisms that have not yet been elucidated. The clinical relevance of its development in these initial phases is unknown, while in more advanced phases new data are required to confirm the close relationship between portal hypertension and the risk of decompensation described in other etiologies. Likewise, the influence of fibrosis and portal hypertension on the cardiovascular risk of patients with NAFLD is unknown. The aim of the present multicenter project is to characterize the presence of portal hypertension and the mechanisms involved in its development in the different stages of NAFLD, to assess the association between the degree of portal hypertension and the development of portal hypertension-related complications, to know the early cardiovascular risk in the different stages of the disease, and to identify noninvasive biomarkers of the presence and severity of portal hypertension.
This study is designated to evaluate the pharmacokinetic interactions of valsartan, amlodipine besylate, rosuvastatin, and ezetimibe in healthy male volunteers.
This study will investigate the acute and chronic effects in hemodynamic and autonomic variables to high-intensity interval versus moderate-intensity continuous heated water-based exercise in older individuals with hypertension.
