Cut-off point of body mass index for malnutrition screening in end stage lung disease

Background: Malnutrition is one of the serious complications in end stage lung disease that affects quality of life, mortality rate and lung transplantation outcome. Objective: The aim of this was to determine the cut-off point of body mass index (BMI) for malnutrition screening in end stage lung disease. Methods: This cross-sectional study was conducted in 86 patients referred to the lung transplant clinic of Masih Daneshvari Hospital from July 2012 to February 2013. Nutritional status was evaluated using anthropometric measurements including Mid-Arm Muscle Circumference (MAMC), Triceps Skinfold (TSF), BMI, and Fat-Free Mass Index (FFMI). With ROC curve analysis, the cut-off point of BMI for diagnosis of patients with MAMC and SFT<25% and FFMI<5% of normal range was determined. Data were analyzed using Chi-square test and T-test. Findings: Mean age was 36.7±13.73. Mean BMI was 21.1±5.12 kg/m2 , mean TSF was 11.76±7.79 mm, mean MAMC was 21.41±3.93 cm2 , and mean FFMI was 16.69±2.35 kg/m2 . Twenty eight patients (32.6%) had FFMI<5% and MAMC and SFT<25% of normal range. In ROC curve analysis, the cut-off point of BMI for malnutrition was 19.4 kg/m2 with sensitivity of 0.844, specificity of 0.842, Youden Index of 0.686 and Shortest distance from the point (0, 1) of 0.0493. Conclusion: With regards to the results, it seems that the cut-off point of BMI for malnutrition screening is 19.4 kg/m2 in patients with end stage lung disease.

Survey the status and trend of traffic accidents in Qazvin Province (2006-2015)

Background: The road traffic accidents (RTAs) have caused life losses and economical damages in Iran. In spite of the high rate of RTAs and related death, no study has been conducted on RTAs in Qazvin province. Objective: The aim of this study was to explore the status and trend of RTAs in Qazvin from 2006 to 2015. Methods: This is a 10 years epidemiological study on documented data in accidents recording system (ARS) at non-communicable disease control center of Qazvin. ARS is an intelligent managed system in which the figures of all accidents and injuries records. All data from ARS were extracted from RAS by an expert staff and analyzed. Findings: Total number of traffic accidents in Qazvin from 2006 to 2015 was 65945; the central city (Qazvin) with 50168 and Takestan city with 7213 were in the top position of RTAs in Qazvin. The number of RTAs was associated with fluctuation, annually. The lowest and highest number of RTAs have been occurred in 2014 (n=5720) and 2012 (n=9718), respectively. Conclusion: This study revealed the increasing trend of RTAs specific rates per thousands of population from 2013 which has direct and indirect cost effects on the community.
