Volume Assessment in Hemodialysis: A Comparison of Present Methods in Clinical Practice with Sonographic Lung Comets.

Dry weight assessment in dialysis patients remains a challenging endeavor owing to the limitations of the available methods for volume assessment. Lung ultrasound is emerging as an invaluable tool to assist in the appropriate assessment and assignment of dry weight. The objectives of this study are (1) to determine the reliability of clinical signs and symptoms for volume assessment, (2) to compare lung ultrasound with High Resolution Computed Tomography (HRCT) chest-A noninvasive gold standard tool for detecting pulmonary congestion and with inferior vena cava diameter (IVCD) - another time-tested volume assessment method, and (3) to analyze if lung ultrasound could detect dialysis induced fluid status variations. The cross-sectional study involves 50 patients on maintenance hemodialysis. Lung ultrasound for B line estimation and ultrasonographic measurement of IVCD performed before and after hemodialysis by a nephrologist trained in ultrasonography. Limited HRCT was obtained just before hemodialysis. Edema, crackles, and dyspnea had a poor sensitivity of 37.9%, 11.5%, and 52.6%, respectively, to detect clinically significant pulmonary congestion by lung ultrasound. A highly significant correlation was obtained between B-line score and HRCT signs of pulmonary congestion (P < 0.001) before dialysis. B lines showed statistically significant reduction with dialysis. The absolute reduction of B lines showed significant correlation with ultrafiltration volume and weight loss. Bedside lung ultrasound appears a sensitive tool for evaluating real-time changes in extravascular lung water and would serve to optimize volume status in dialysis patients.

Depression, Suicidal Ideation, and Resilience among Rural Farmers in a Drought-Affected Area of Trichy District, Tamil Nadu.

BACKGROUND: Changes in climatic conditions and other factors including trade and commerce have influenced agriculture worldwide. These factors have created a crisis among farmers. OBJECTIVES: The objective of this study was to find out the prevalence of depression and suicidal ideation, to measure the resilience, and to find out the factors that influence depression and resilience among farmers. MATERIALS AND METHODS: A community-based cross-sectional analytical study was performed among farmers residing in a drought-affected area of Tiruchirappalli district of Tamil Nadu. The sample size was 191 and cluster sampling was used to select the participants. Structured, pretested questionnaires were used to find the prevalence of depression, suicidal ideation, and resilience among farmers. Pearson Correlation, Student's t-test, analysis of variance, and Pearson Chi-square test were used to identify the factors influencing depression and resilience. RESULTS: A total of 194 farmers participated in the study. The mean age of the farmers was 46.68 ± 12.6 years, majority 64% were males and 89% were literates. Among the participants, 97.4% had some form of depression, and 67% had severe depression. About 60% of the farmers had suicidal ideation. Male farmers, farmers with few years of farming experience, and severe reduction in yield had a higher level of depression. Suicidal ideation was influenced by gender, small-scale farming, fewer years of experience in farming, and the impact of drought on yield. The mean resilience score was 49.4 ± 10. Gender and years of experience in farming had a significant association with resilience. CONCLUSION: High prevalence of depression and suicidal ideation and low level of resilience has been observed among the farmers. Interventions need to be provided for marginal and small-scale farmers, male farmers in the affected area to reduce the impact of drought in these farmers.

Determinants of Awareness and Practice of Breast Self Examination Among Rural Women in Trichy, Tamil Nadu.

INTRODUCTION: Breast cancer is the most common cancer among women worldwide, and it can be detected at an early stage through self-examination which increases the chance of survival. This study aimed to assess knowledge and practice of breast self-examination (BSE) among females in a rural area of Trichy district. METHODOLOGY: This community-based, cross-sectional study was carried out among a total sample of 200 women in rural area of Trichy. The participants were interviewed using a structured interviewer-administered questionnaire to obtain information on their sociodemographic characteristics, awareness on breast cancer, and knowledge, attitude, practice of BSE. Data were entered into MS Excel and analyzed using SPSS version 20.0. Spearman correlation and Chi-square test were used to analyze the association between the variables. RESULTS: The mean age of the study group was 36.9 ± 8.8 years. Eighty percent were literates. Most of the women 178 (89%) were aware of breast cancer. Only 26% of the women were aware of BSE. Only 18% of the females had ever checked their breast and 5% practiced it regularly. Awareness of BSE was found to be significantly associated with age and educational attainment. CONCLUSION: The level of knowledge and practice of BSE among females are unacceptably low. Efforts should be made to increase level of knowledge and practice of BSE through health education programs.

Alcohol use disorders among pulmonary tuberculosis patients under RNTCP in urban Pondicherry, India.

BACKGROUND: Alcohol use is implicated in a wide variety of diseases and disorders including TB. OBJECTIVES: To study the prevalence and pattern of alcohol use among the PTB patients registered under RNTCP in urban Pondicherry and the association of various socio-demographic variables with alcohol drinking during treatment. METHODS: A cross-sectional study was conducted among 235 PTB patients from 6 randomly selected urban PHCs of Pondicherry from Jan 2013 to March 2014. Alcohol Use Disorder Identification Test (AUDIT) was used for screening the PTB patients for their severity of alcohol use. Data were entered in Epi-data v3.1 and was analyzed by SPSS v20. Chi-square test and multiple-logistic regression were used. RESULTS: Prevalence of alcohol use among PTB patients at the time of diagnosis was 59% and during treatment was 31.5%. Around 54% PTB patients had alcohol use disorders (AUD) during diagnosis, whereas the same during treatment was 26.4%. Among drinkers at the time of diagnosis (n=139), 80% modified and 20% did not modify their alcohol use even after TB diagnosis. Male gender was significantly associated with alcohol use (p≤0.001). Univariate analysis showed that lower level of education, lower SES, unemployed/unskilled/semiskilled/skilled occupational group, and Category II were significantly associated with alcohol use among male patients (p<0.05). Multivariate analysis showed that none of the variables were associated. CONCLUSIONS: One-third of PTB patients were drinking alcohol during the treatment. Though 80% modified alcohol use after TB diagnosis, the rest 20% did not modify. Necessary interventions need to be planned to screen for alcohol use.

Two new flavonoids from Centella asiatica (Linn.).

Two new flavonoids named castilliferol 1 and castillicetin 2, as well as a known compound, isochlorogenic acid 3, were isolated from the whole plant of Centella asiatica. Isolates 1 and 2 exhibited good antioxidant activity using 2,2-diphenyl-1-picryl hydrazyl radical solution with IC(50) values of 23.10 and 13.30, respectively. The structures of these isolates were determined by analytical and spectral data, including 1-D and 2-D NMR spectra.
