BACKGROUND: Muscle weakness is a risk factor for mortality in hemodialysis (HD) patients. Muscle strength measurements are routinely used as a screening tool but depend on patient cooperation and motivation. We wished to determine whether measuring maximal voluntary muscle strength was affected by patient self-reported distress. METHODS: We measured pinch strength (PS) and handgrip strength (HGS) in 382 adult HD patients with a corresponding self-reported distress thermometer (DT) scores...

We report a case of intrapulmonary ectopic liver associated with Scimitar syndrome. A two month old male child who presented with features of congestive cardiac failure underwent extensive cardiac and radiological investigations and was diagnosed with Scimitar syndrome. He was also found to have a mass in the lower lobe of the right lung, the possibilities being either a pulmonary sequestration or a diaphragmatic hernia. As his dyspnea progressively worsened, a right lower lobectomy was performed at the age of two years...

Many functions of the cardiovascular apparatus are affected by gender. The aim of our study was find out whether markers of cell death present in the donor myocardium differ in male and female hearts. The study involved 81 patients undergoing heart transplantation from September 2010 to January 2013. Patients were divided into two groups: male allograft (n=49), and female allograft (n=32). Two types of myocardial cell death were analyzed. High-sensitive cardiac troponin T as a necrosis marker and protein bcl-2, caspase 3 and TUNEL as apoptosis markers were measured...

Cardiac metastases from sarcoma are uncommon. Due to their rarity there is not a standard of care. However, complete cardiac metastases resection is the best option but most of patients has widespread disease. In these patients palliative radiotherapy (RT) might improve symptoms and prevent further cardiac function decline. Here we present the case of a symptomatic 30-year-old woman with spindle cell sarcoma metastasis of right ventriculum and widespread disease. The patient received radiotherapy to the heart with palliative intent...

On the effort to screen antibiotics against Methicillin resistant Staphylococcus aureus (MRSA), an actinomycete strain which can produce bactericidal compound was isolated from a marine sponge of Kanyakumari Coast, India. Two anti-MRSA compounds (PVI401 and PVI402) were isolated from the fermentation plates of Streptomyces pharmamarensis ICN40. TLC bioautography analysis yielded two active spots with Rf value of 0.75 (PVI401) and 0.8 (PVI402) from the crude extract. Both the compounds were characterized by HR-LC-MS analysis...

INTRODUCTION: Chronic constipation is very common in elderly patients. As a result of this situation fecaloma is also frequently seen at these ages. However, the stercoral perforation caused by fecaloma is a rare situation to occur. The rectosigmoid colon is the most affected colonic segment. It is seen in older patients with concomitant diseases and a low quality of life. PRESENTATION OF CASE: Here in this case, we have to report an 83 - year-old male patient who came to the emergency room with complaints of abdominal pain and constipation for two days...

BACKGROUND: Both ECG strain pattern and QRS measured left ventricular (LV) hypertrophy criteria are associated with LV hypertrophy and have been used for risk stratification. However, the independent predictive value of ECG strain in apparently healthy individuals in predicting mortality and adverse cardiovascular events is unclear. METHODS AND RESULTS: MESA (Multi-Ethnic Study of Atherosclerosis) is a multicenter, prospective cohort of 6441 participants (mean age, 62 years; 54% women)...

Muscle wasting, also known as cachexia, is associated with many chronic diseases, which worsens prognosis of primary illness leading to enhanced mortality. Molecular basis of this metabolic syndrome is not yet completely understood. SIRT6 is a chromatin-bound member of the sirtuin family, implicated in regulating many cellular processes, ranging from metabolism, DNA repair to aging. SIRT6 knockout (SIRT6-KO) mice display loss of muscle, fat and bone density, typical characteristics of cachexia. Here we report that SIRT6 depletion in cardiac as well as skeletal muscle cells promotes myostatin (Mstn) expression...

BACKGROUND: The human aorta dilates with advancing age. However, the association between progressive aortic dilation with aging and cardiac remodeling has not been established in studies of community-dwelling adults. The aim of this study was to test the hypothesis that there would be a relationship between aortic size increase over the early adult life span with left ventricular (LV) structural remodeling and subclinical LV dysfunction in middle age, even in the absence of overt cardiovascular and valvular disease...

BACKGROUND: Patients with acute leukemia (AL) have a higher rate of congestive heart failure than patients with other cancers. AL may predispose to cardiac dysfunction before chemotherapy because of high cytokine release or direct leukemic myocardial infiltration. The aims of this study were to evaluate whether AL is associated with abnormalities of myocardial structure and function before chemotherapy and to identify possible risk factors associated with these myocardial changes. METHODS: Using an echocardiographic database, 76 patients with AL and 76 patients without cancer matched for age, gender, hypertension, and the presence of diabetes were retrospectively selected...

Respiratory parameters such as flow or rate have complex effects onto exhalation of volatile substances and can hamper clinical interpretation of breath biomarkers. We investigated effects of progressively applied upper-airway resistances onto exhalation of volatile organic compounds (VOCs) in healthy humans. We performed real-time mass-spectrometric determination of breath volatiles in 50 subjects with parallel non-invasive hemodynamic monitoring, breath-resolved spirometry and capnometry during controlled tidal breathing (12 breaths/min)...

BACKGROUND: Cardiovascular disease is the major cause of death in patients with chronic kidney disease, even after renal transplantation. Cardio-ankle vascular index (CAVI) provides an indicator of arterial stiffness, whereas fibroblast growth factor-21 (FGF-21) levels may provide a biomarker for atherosclerotic disease. We investigated the association between CAVI and FGF-21 and their relationships to carotid intima-media thickness (IMT) and other cardiovascular risk factors. METHODS: This study included 90 renal transplant patients...

Objectives Non-chylous lymphorrhagic pleural effusions are transudative effusions with a predominance of lymphocytes; however, they do not contain chylomicrons and therefore do not have the classical milky aspect of true chylous effusion. This type of effusion has been anecdotally associated with cardiac diseases in cats, but studies are lacking. The aim of this study was to investigate the association between this type of effusion and the primary disease. Methods In this study, feline non-chylous lymphorrhagic pleural effusions were retrospectively selected from the database of the authors' institutions over a 3 year period...
