Ramadan during pregnancy and neonatal health-Fasting, dietary composition and sleep patterns.

BACKGROUND AND OBJECTIVES: Large shares of pregnant Muslims worldwide observe the Ramadan fast. Previous research showed that Ramadan during pregnancy is associated with adverse offspring health outcomes lasting throughout the life-course. Evidence on effects on birth outcomes is inconclusive, however, and previous research did not consider the role of dietary composition and sleep patterns during Ramadan. This study systematically documents maternal lifestyle during Ramadan and assesses if diet and sleep adaptations to Ramadan, independent of and in addition to maternal fasting, are associated with neonatal health outcomes. METHODS: This study reports a survey of 326 Muslims who delivered their baby in Mainz, Germany, linked to maternal & infant hospital records. Participants reported on fasting, dietary composition and sleep schedules while pregnant during Ramadan. RESULTS: Fasting during pregnancy was associated with reduced birthweight, in particular for fasting during the first trimester (-352ˑ92g, 95% CI: -537ˑ38; -168ˑ46). Neither dietary composition nor altered sleep were directly associated with birthweight. However, dietary composition during Ramadan outside of fasting hours seems to moderate the fasting-birthweight association, which disappeared for women switching to high-fat diets. CONCLUSIONS: The finding that dietary intake during Ramadan potentially moderates the fasting-birthweight association is of high relevance to pregnant Muslims who wish to fast and their healthcare professionals, since dietary choices outside of fasting hours are often relatively easily modifiable. This is the first study to include information on maternal diet and sleep during Ramadan, and additional research is needed to assess the roles of specific (macro)nutrients and food groups.

Costs of a structured early detection program for advanced liver fibrosis and cirrhosis: insights on the "plus" of Check-up 35.

BACKGROUND: The implementation of an early detection program for liver cirrhosis in a general population has been discussed for some time. Recently, the effectiveness of a structured screening procedure, called SEAL (Structured Early detection of Asymptomatic Liver cirrhosis), using liver function tests (AST and ALT) and APRI to early detect advanced fibrosis and cirrhosis in participants of the German "Check-up 35" was investigated. METHODS: This study identifies the expected diagnostic costs of SEAL in routine care and their drivers and reports on prevailing CLD etiologies in this check-up population. The analysis is based on theoretical unit costs, as well as on the empirical billing and diagnostic data of SEAL participants. RESULTS: Screening costs are mainly driven by liver biopsies, which are performed in a final step in some patients. Depending on the assumed biopsy rates and the diagnostic procedure, the average diagnostic costs are between EUR 5.99 and 13.74 per Check-up 35 participant and between EUR 1,577.06 and 3,620.52 per patient diagnosed with fibrosis/cirrhosis (F3/F4). The prevailing underlying etiology in 60% of cases is non-alcoholic fatty liver disease. DISCUSSION: A liver screening following the SEAL algorithm could be performed at moderate costs. Screening costs in routine care depend on actual biopsy rates and procedures, attendance rates at liver specialists, and the prevalence of fibrosis in the Check-up 35 population. The test for viral hepatitis newly introduced to Check-up 35 as once-in-a-lifetime part of Check-up 35 is no alternative to SEAL.
