RESUMO
Objective:To evaluate the nutritional status of patients with decompensated liver cirrhosis and explore the correlation with malnutrition and the risk factors of depressed mood.Methods:190 cirrhotic patients admitted to the Department of Gastroenterology of the First Hospital of Shanxi Medical University from June to September 2023 were selected according to the inclusion and exclusion criteria. Eligible patients were divided into subgroups based on the presence or absence of malnutrition as determined by subjective global assessment (SGA). The Center for Epidemiological Studies Depression (CES-D) scale was used to assess patients' propensity for depressed mood. Relevant clinical data were also collected and analyzed.Results:A total of 185 patients were included, of which 126 were in the non-malnutrition group and 59 malnutrition group. There were significant between-group differences in terms of CES-D results, age, body mass index, platelets, D-dimer, serum sodium, third lumbar skeletal muscle index, grip strength, triceps skinfold thickness, and upper arm muscle circumference (all P<0.05). Correlation analysis showed that grip strength, triceps skinfold thickness, upper arm muscle circumference, serum sodium, and depressed mood tendency status were correlated with the development of cirrhotic malnutrition ( P<0.05). The diagnostic model for malnutrition in cirrhosis using these five indicators showed the area under the curve of 81.9%. Conclusions:Depression is closely related to the development of malnutrition in patients with liver cirrhosis. Independent risk factors for malnutrition in cirrhosis include serum sodium≤135 mmol/L, grip strength, triceps skinfold thickness, lower-than-normal upper arm circumference , and the tendency of depression , which demonstrate the combined contribution to the diagnosis of malnutrition in cirrhosis.
RESUMO
<p><b>OBJECTIVE</b>To assess the cardiopulmonary exercise testing (CPET) derived performance of oxygen uptake and ventilation efficiency parameters, including oxygen uptake efficiency plateau (OUEP) , oxygen uptake efficiency slope (OUES), V·E/V·CO2 slope and lowest V·E/V·CO2, in patients with end-stage chronic heart failure (CHF) and evaluate their clinical value on monitoring cardiac function and hemodynamic status.</p><p><b>METHODS</b>A total of 26 end-stage CHF patients considered for heart transplantation were enrolled in this study. CPET, echocardiography and invasive hemodynamic examinations with Swan-Ganz flowing balloon catheter were performed. Correlation analysis was made between oxygen uptake and ventilation efficiency parameters from CPET and echocardiographic and hemodynamic parameters.</p><p><b>RESULTS</b>OUEP and OUES showed good correlation with peak oxygen consumption (peak V·O2) (r = 0.535, P < 0.01;r = 0.840, P < 0.001). In end-stage CHF patients, the slope of OUEP with respect to peak V·O2 is about 32, but the slope of OUES with respect to peak V·O2 is only about 2. The difference was 16 times. The change of OUEP was more sensitive and significant than those of OUES and peak V·O2 (P < 0.05). OUEP, peak V·O2 (%pred), V·E/V·CO2 slope and lowest V·E/V·CO2 were all correlated well with non-invasive hemodynamic parameters peak cardiac output (r = 0.535, P < 0.01; r = 0.652, P < 0.001; r = -0.640, P < 0.001; r = -0.606, P = 0.001 respectively) and peak cardiac index (r = 0.556, P < 0.01;r = 0.772, P < 0.001; r = -0.641, P < 0.001; r = -0.620, P < 0.001 respectively) derived from CPET, but not correlated with invasive hemodynamic parameters cardiac output and cardiac index at rest (P > 0.05). Both peak V·O2 (%pred) and V·E/V·CO2 slope were significantly correlated with invasive hemodynamic parameters systolic pulmonary arterial pressure (r = -0.424, P < 0.05; r = 0.509, P < 0.01) and mean pulmonary arterial pressure (r = -0.479, P < 0.05; r = 0.405, P < 0.05). Peak V·O2 (%pred) was also significantly correlated with pulmonary capillary wedge pressure (r = -0.415, P < 0.05), and V·E/V·CO2 slope was significantly correlated with pulmonary vascular resistance (r = 0.429, P < 0.05).</p><p><b>CONCLUSIONS</b>The oxygen uptake and ventilation efficiency parameters derived from CPET, including peak V·O2, OUEP, lowest V·E/V·CO2 and V·E/V·CO2 slope etc, are objectively monitoring and evaluating cardiac function and hemodynamic status. And they are useful for optimizing clinical management of patients with end-stage CHF.</p>

The objective of the study was to estimate the prevalence of hypertension and associated factors among older rural adults in Liaoning Province, China. The study was conducted in 2004-2006, using a multistage, stratified clustering sampling scheme to select a representative sample. A total of 10,065 adults aged 60 years or older were examined. A survey of blood pressure and associated factors was carried out. All data analyses were conducted using SPSS 11.5 statistical software package. Overall, the prevalence rates of hypertension are 57, 64.4 and 64.9% for the age groups 60-69, 70-79 and >/= 80 years, respectively. The prevalence of hypertension was positively correlated with age, female gender, Mongolian ethnicity, overweight and obesity, smoking and drinking, whereas income level was a protective factor for hypertension. The rates of awareness, treatment and control among older rural adults were very low [overall 35.2, 28.7 and 1.0%, respectively] Hypertension was highly prevalent among older rural adults in Liaoning Province, and it was associated with many factors. The percentages of hypertensives who were aware, treated, and controlled were very low. These data underscore the urgent need to strengthen the public health education and blood pressure monitoring system to better manager hypertension among older adults in rural China
