\n\nSTUDY DESIGN: PF 00299804 Prospective cohort study of 175 VLBW infants. The average daily dose of HM (ADDHM) was calculated from daily nutritional data for the first 28 days post birth (ADDHM-Days 1-28). Other covariates associated with sepsis were used to create a propensity score, combining multiple risk factors into a single metric.\n\nRESULT: The mean gestational age and birth weight were 28.1 +/- 2.4 weeks and 1087 +/- 252 g, respectively. The mean ADDHM-Days 1-28 was 54 +/- 39 ml kg(-1) day(-1) (range 0-135). Binary logistic regression analysis controlling for propensity score revealed that increasing ADDHM-Days 1-28 was associated with lower odds of sepsis (odds ratio 0.981,

95% confidence interval 0.967-0.995, P = 0.008). Increasing ADDHM-Days 1-28 was associated

with significantly OICR-9429 ic50 lower NICU costs.\n\nCONCLUSION: A dose-response relationship was demonstrated between ADDHM-Days 1-28 and a reduction in the odds of sepsis and associated NICU costs after controlling for propensity score. For every HM dose increase of 10 ml kg(-1) day(-1), the odds of sepsis decreased by 19%. NICU costs were lowest in the VLBW infants who received the highest ADDHM-Days 1-28.”
“Background: Smoking and physical inactivity constitute a major public health concern for Greece. The purpose of this study was to examine smoking behaviour and physical activity (PA) in Greek health science students.\n\nMethods: buy Z-DEVD-FMK A standardised questionnaire and the Greek version of IPAQ-short were given to 2000 health science students, randomly selected from five higher education institutions, in order to record smoking behaviour and PA status. All healthy young adults aged 19-30 years old were eligible. The final cohort size

of the study was 1651 students (690 men).\n\nResults: In the overall population, smoking prevalence was 37.6%, with 23.1% being heavy smokers (>= 21 cig/day). Smoking prevalence did not differ significantly between sexes, but heavy smoking was more prevalent in males. Age at smoking initiation was negatively associated with the daily number of cigarettes smoked (smoking volume), but only in females. The prevalence of health-enhancing PA (high PA(class)) was only 14.2%, while 45.4% of the study population was classified as insufficiently active (low PA(class)). Males were more physically active than females. Logistic regression analysis showed a strong inverse association between smoking and PA that was more pronounced in males. Smoking was associated with significantly decreased odds of being either moderately or highly physically active. Smoking volume was also negatively related with PA, but this relation was more pronounced in females.\n\nConclusion: Smoking prevalence and rates of physical inactivity are considerably high in Greek health science students. Smoking was strongly and inversely associated with PA in this sample of Greek young adults.
