In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

[EX Q]: Context: Sleep disorders are associated with cardiovascular complications and preterm delivery (PTD). Insufficient sleep results in metabolic alterations and increased inflammation, both known to contribute to placental abruption (abruption), a determinant of PTD. We examined associations of abruption with sleep duration and complaints of vital exhaustion.', 'The study included 164 abruption cases and 160 controls in a multicenter study in Peru. Data on habitual sleep duration and vital exhaustion during the first 6 months of pregnancy were elicited during interviews conducted following delivery. Women were categorized according to short, normal and long sleep duration (≤6, 7-8 and ≥9\u2009h); and frequency of feeling exhausted. Odds ratios (OR) and 95% confidence intervals (CI) were calculated.', 'Short and long sleep durations were associated with increased odds of abruption. The ORs of abruption in relation to short (≤6\u2009h) and long (≥9\u2009h) sleep duration were 2.0 (95% CI 1.1-3.7) and 2.1 (95% CI 1.1-4.1), compared with normal sleep duration (7-8\u2009h). Complaints of vital exhaustion were also associated with abruption (OR\u2009=\u20092.37; 95% CI 1.46-3.85), and were independent of sleep duration.\Question: Is maternal sleep duration and complaints of vital exhaustion during pregnancy associated with placental abruption?
[EX A]: We extend the existing literature and support the thesis that maternal sleep habits and disorders should be assessed among pregnant women.

[EX Q]: Context: The study focuses on the analysis of the possible relationship between a common NYD-SP18 (rs6971091, G>A) gene polymorphism and weight loss after lifestyle intervention (combined dietary intake and physical activity) in overweight/obese females.', 'We genotyped 139 unrelated non-diabetic Czech females (49.5 ± 13.3 years, average BMI at baseline 32.2 ± 4.6 kg/m². Biochemical and anthropometrical measurements were performed before and after ten weeks of lifestyle intervention.\Question: Do body Composition Changes in Adult Females after Lifestyle Intervention Are Influenced by the NYD-SP18 Variant?
[EX A]: Overweight/obese female carriers of the NYD-SP18 rs6971091 GG genotype exhibited a more beneficial response to the intensive lifestyle intervention than others.

[EX Q]: Context: MiR-378 has been reported to be related to cell survival, tumor growth and angiogenesis and may participate in hepatocellular carcinoma (HCC) development and prognosis. Genetic variants in primary miR-378 (pri-miR-378) may impact miR-378 expression and contribute to HCC risk and survival. This study aimed to assess the associations between a genetic variant in primary miR-378 and HCC susceptibility and prognosis.', 'We conducted a case-control study to analyze the association of rs1076064 in pri-miR-378 with hepatocellular carcinoma risk in 1300 HCC patients with positive hepatitis B virus (HBV) and 1344 HBV carriers. Then, we evaluated the correlation between the polymorphism and hepatocellular carcinoma prognosis in 331 HCC patients at either intermediate or advanced stage without surgical treatment.', 'The variant genotypes of rs1076064 were associated with a decreased HCC risk in HBV carriers [Adjusted odds ratio (OR)\u200a=\u200a0.90, 95% confidence intervals (CI)\u200a=\u200a0.81-1.00, P\u200a=\u200a0.047]. Moreover, HCC patients with the variant genotypes were associated with a better survival [Adjusted hazard ratio (HR)\u200a=\u200a0.70, 95% CIs\u200a=\u200a0.59-0.83, P<0.0001 in an additive genetic model]. The reporter gene assay showed that the variant G allele of rs1076064 exerted higher promoter activity than the A allele.\Question: Is a genetic variant in primary miR-378 associated with risk and prognosis of hepatocellular carcinoma in a Chinese population?
[EX A]:
These findings indicate that rs1076064 may be a biomarker for HCC susceptibility and prognosis through altering pri-miR-378 transcription.
