instruction:
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.
question:
Context: It has been shown that maternal mental health is associated with poorer skills development in the offspring. However, the evidence evaluating the association between social anxiety disorder (SAD) and cognitive or language development, is scarce.', 'To evaluate the association between maternal SAD and performance in cognitive and language tests in 30-month old children.', 'This was a cohort study involving young women evaluated since pregnancy.', 'We evaluated 520 mother-child dyads who received prenatal medical assistance through the National Public Health System in a southern Brazilian city, from October 2009 to March 2011.', 'We used the Mini Neuropsychiatric Interview Plus (MINI Plus) to assess SAD among young mothers. Cognitive and language performance in their offspring was analyzed using the Bayley Scales of Infant and Toddler Development - 3rd Edition.', 'We found an association between maternal SAD and performance in cognitive and language tests. Children of mothers with SAD had in average 4.5 less points in the Bayley scale, when compared to those with mothers without SAD: in the cognitive (β=-4.53 [95% CI -7.8; -1.1] p=0.008) and language subscales (β=-4.54 [95% CI -9.0; -0.5] p=0.047).\Question: Is cognitive and language performance in children associated with maternal social anxiety disorder : A study of young mothers in southern Brazil?
answer:
Our findings suggest that children with mothers suffering from SAD have poorer cognitive abilities and language skills.


question:
Context: Abnormalities of serum sodium are common after subarachnoid hemorrhage (SAH) and have been linked to poor outcome. This study analyzed whether abnormal serum sodium levels are associated with cardiac outcomes and mortality after subarachnoid hemorrhage (SAH).', "In a prospective cohort study of SAH patients, the primary predictor variable was subjects' sodium level. Hypernatremia was defined as sodium >143 mmol/L and hyponatremia was <133 mmol/L. Cardiac troponin I (cTi) was measured and echocardiography was performed on three study days. Dichotomous outcome variables were cTi > 1.0 microg/L, left-ventricular ejection fraction (LVEF) <50%, presence (vs absence) of regional wall motion abnormalities (RWMA) of the LV, pulmonary edema, and death. Additional analyses studied the degree of hypernatremia and sodium supplementation, and the temporal relationship between hypernatremia and cardiac outcomes.", 'The study included 214 subjects. Forty-eight subjects (22%) were hypernatremic on at least one study day, and 45 (21%) were hyponatremic. After multivariate adjustment, hypernatremia was an independent predictor of LVEF <50% (OR 4.7, CI 1.3-16.2, p = 0.015), elevated cTi (OR 3.7, CI 1.2-11.9, p = 0.028), and pulmonary edema (OR 4.1 CI 1.4-1.5, p = 0.008). It was not, however a statistically significant predictor of mortality (p = 0.075).\Question: Does hypernatremia predict adverse cardiovascular and neurological outcomes after SAH?
answer:
In the acute period after SAH, hypernatremia is associated with adverse cardiac outcomes and death. SAH patients with hypernatremia should be monitored for evidence of cardiac dysfunction.


question:
Context: Correlation between the gross classification of hepatocellular carcinoma (HCC) and its vascular invasion or intrahepatic metastasis has been reported previously. Because E-cadherin-mediated epithelial cell-to-cell adhesion is thought to suppress cancer cell invasion, the present study was performed to analyze the correlation between E-cadherin expression and the gross classification of HCC.', 'Thirty-six resected solitary HCC <6 cm in diameter were each classified as single nodular type (type 1), single nodular with extranodular growth type (type 2) or contiguous multinodular type (type 3), and the clinicopathological and prognostic differences between type 1 HCC and the other types were analyzed. The expression of E-cadherin in each tumor was examined by immunoblotting and immunohistochemical analysis.', 'Vascular invasion and microscopic intrahepatic metastasis were observed more frequently in types 2 and 3 (61%) than in type 1 (13%) HCC. Immunoblot analysis indicated that the relative level of E-cadherin expression in cancerous tissue was significantly lower in type 2 and 3 (0.75 +/- 0.49) than in type 1 (1.46 +/- 0.79) HCC. Immunohistochemical examination revealed decreased and partially absent E-cadherin expression in the tumorous area of type 2 and 3 HCC. The recurrence-free survival rate was higher for patients with type 1 HCC than for those with the other types.\Question: Does gross appearance of hepatocellular carcinoma reflect E-cadherin expression and risk of early recurrence after surgical treatment?
answer:

Types 2 and 3 HCC have marked metastatic and invasive potential and reduced expression of E-cadherin, predicting a high risk of recurrence after surgical treatment.
