Active clinical trials for "Sarcopenia"

Assess the influence of sarcopenia on outcomes of emergency laparotomy in the over 65 age group

This study aimed to evaluate the correlation of change in body composition and oncological outcomes of prostate cancer patients under androgen deprivation therapy(ADT).

Using abdominal computed tomography (CT) imaging, the investigators will estimate total body muscle mass at two time points in Intensive Care Unit (ICU) by assessing cross-sectional muscle areas at the L3 vertebral body level. This allows for a determination of the rate of sarcopenia development in the ICU. With this information, the investigators propose to test if the rates of the development of sarcopenia differ in critically ill subjects with sepsis compared to a reference group of critically ill subjects with trauma (without sepsis).

Obesity sarcopenia, characterized by the coexistence of excess fat and muscle mass reduction, may contribute to the pathophysiology of exercise intolerance in patients with heart failure with preserved ejection fraction (HFpEF). The project will examine the impact of selected circulating miRNAs on processes that may form the pathophysiological basis for HFpEF development and obesity sarcopenia in correlation with biochemical markers, echocardiographic assessment and non-invasive assessment of hemodynamic parameters. In addition, the impact of LDL and HDL on these diseases will be assessed. Determinations of selected adipokines and asymmetric dimethylarginine will also be carried out and their effects on the cardiovascular system will be assessed.

Traditionally, muscle mass - a part of the concept of sarcopenia - is measured by computed tomography (CT) or dual-energy X-ray absorptiometry (DEXA) scan. These devices are not always easily available in clinical practice and cannot be used bedside. An innovation in sarcopenia is the assessment of muscle mass and quality with ultrasound. Because this device is much more available and applicable in all patients, diagnosis of acute sarcopenia would be much easier with ultrasound. Moreover, if other factors that contribute to accelerated decline in muscle mass and function can be determinated, the sensiblisation and early screening for acute sarcopenia in those individuals can hopefully prevent them from declining.

Sarcopenia is a syndrome characterized by progressive and generalized loss of skeletal muscle mass and strength, shown to be prevalent in adults with cancer and common chronic comorbidities such as liver cirrhosis. The EWGSOP identified a grading for Sarcopenia into pre-sarcopenia (decreased muscle mass with normal strength and physical performance), sarcopenia (decreased muscle mass with decreased strength or performance), severe Sarcopenia (decreased muscle mass, strength and performance) . Sarcopenia has emerged as an independent predictor of poor prognosis in a variety of clinical conditions.Sarcopenia is clinically important because it can affectthe quality of life of patients with cirrhosis . Skeletal muscle mass is not only a good indicator of nutrition in patients with cirrhosis, but also has recently been shown to be closely associated with survival prognosis and postoperative complications inHCC. Combination of sarcopenia and the Model for End-stage Liver Disease (MELD) has been shown to be an excellent model for predicting prognosis in decompensated liver cirrhosis . Most patients awaiting liver transplantation (LT) are more or less in a state of sarcopenia. Several studies have reported that sarcopenia was associated with worse prognosis.In addition, sarcopenia may be associated with a higher risk of post-transplant infection . Assessment of sarcopenia in patients with liver cirrhosis:_ The European Working Group on Sarcopenia in Older People recommended that the definition of sarcopenia include not only low muscle mass but also low muscle function . They recommended cutoff values for muscle mass measurements (7.26 kg/m2 for men and 5.5 kg/m2 for women using dual X-ray absorptiometry, and 8.87 kg/m2 for men and 6.42 kg/m2 for women using bioimpedance analysis, handgrip strength (<30 kg for men and <20 kg for women), and usual gait speed (<0.8 m/s). Aim of the study To evaluate sarcopenia in different stages of liver cirrhosis by different diagnostic methods. To identify the prognostic value of CT in the diagnosis of sarcopenia . To identify effect of sarcopenia inliver transplant candidate. Patients and methods: Type of the study:the study is divided into two parts First part: observational descriptive cross sectional study. Second part: follow up of liver transplant candidate group (pre and post liver transplantation) Duration of study: expected duration of the study will be 1.5 years . The 1st part will include all patients admitted to the department for 1 year fulfill inclusion criteria . 2nd part will be 6 ms follow up after liver transplantation. Study population st part : Patients with liver cirrhosis will be evaluated for the presence of sarcopenia. nd part: 13 cases of liver cirrhosis already done liver transplantation in AL Rajhiuneversitiy hospital(which data already recoreded) and any cirrhotic pts will be prerared for liver transplantion within six months. Methods At the study entry, all candidates will be subjected to the following parameters (and 3 month after LT for liver transplant candidates only) Clinical history Clinical examination Abdominal ultrasound Laboratory investigation: Liver function tests Complete blood picture, Kidney function tests, Serum glucose, serum Na+ and K+ Hepatitis markers (HBsAg, HCV-Ab) Calculate: = Child Pugh score (Pugh et al., 1973) and MELD (Wiesner et al., 2003) scores for assessment ofliver cirrhosis. Anthropometric measurements: Triceps skin fold thickness (TSF) . Measure mid-arm circumference (MAC). Body mass index Hand grip to assess muscle strength Gait speed to assess physical performance Assessment of sarcopenia using CT scan: Assessment of sarcopenia using ultrasound: Assessment of sarcopenia using bioimpedance analysis

This study will examine the influence of n3 PUFA supplementation on the rate of muscle atrophy in older women undergoing 1 week of unilateral limb immobilization. Assessments in skeletal muscle strength and skeletal muscle volume will also me made before, after and in recovery from immobilization.

The primary aim of the study is to assess the mobility dose in neurocritical care patients with ischemic stroke or intracranial hemorrhage and its effects on discharge disposition and patient outcomes. The investigators hypothesize that patients' mobilization dose in the intensive care unit (ICU) predicts discharge disposition, 90 day Barthel Index and other outcomes like muscle wasting (expressed as decrease in rectus femoris cross sectional area (RF-CSA) in the paretic and non-paretic limb measured by bedside ultrasound), and ICU length of stay (LOS).

The objective of our study is to evaluate the prevalence of sarcopenia and sarcopenic obesity in our surgical population and their relationship in postoperative complications after complex abdominal wall surgery and its influence on hernia recurrence. This is a retrospective study on a prospective maintains database of complex abdominal wall surgery. We select patients with defects larger than 10 cm from any location (W3 of the EHS classification), excluding other causes of complex abdominal wall in order to have a more homogeneous sample. Pre-surgical computed tomography (CT) scans of the selected patients will be reviewed to establish the diagnosis of sarcopenia, obesity, sarcopenia-obesity or the absence of these (normal). The CT scans will be reviewed by two trained investigators, blinded to postoperative complications and survival. In case of disagreement, a third investigator will break the tie. The radiological diagnosis of sarcopenia has been established based on the skeletal muscle mass index. Skeletal muscle mass measurement will be performed in a cross-section in the pre-surgical CT scan at the level of the third lumbar vertebra (L3). The BMI, the Visceral Fat Area and the Subcutaneous Fat Area (SFA) will also be measured. With the previous data, the VFA / SFA ratio will be calculated. The study will be completed with the collection of sociodemographic data, comorbidities and presence of risk factors for the development of incisional hernia, ASA, size and location of the hernia, surgical technique, postoperative complications according to Clavien-Dindo, stay, readmission, late complications and hernia recurrence. Likewise, the presence or absence of recurrence will be collected. Statistical analysis will be performed to see if there is a correlation between sarcopenia and sarcopenic obesity with the appearance of local and systemic complications and recurrence. To evaluate the independent contribution of each variable to the presence of complications, a univariate and multivariate logistic regression analysis will be performed.

With increasing age and the additional impact from the bowel cancer and the chemotherapy and/ or radiotherapy it has been described that testosterone (a male hormone produced naturally in the body) levels are reduced. Testosterone has an impact on numerous body functions including the muscle mass and quality. Previous studies have identified that muscle mass is reduced as a result of ageing but also because of the deleterious effect of cancer and chemotherapy and/or radiotherapy. There is growing evidence from published studies that patients with better muscle mass and quality, do better after surgery. Mr Jenkins and his team are therefore looking at ways, the investigators can try and prevent or reduce this muscle loss and therefore improve patient outcomes. The aim of this study is to assess whether using testosterone replacement therapy in the form of a topically applied gel daily for a total of 12 weeks, is feasible and acceptable by the patients who are diagnosed with colorectal cancer and are waiting to undergo surgery. The investigators will also collect information related to the testosterone replacement therapy such as questionnaires on the quality of life, fatigue and muscle mass, and blood biomarker changes in the blood.
