Exposure to selective noradrenalin reuptake inhibitors during the first trimester of pregnancy and risk of congenital malformations: A meta-analysis of cohort studies.

Selective serotonin-noradrenalin reuptake inhibitors (SNRIs) are used to treat depression and anxiety during pregnancy; however, information regarding their foetal safety is limited. Cohort studies concerning congenital malformations in infants born to mothers exposed to SNRIs during the first trimester of pregnancy were identified. Eight studies were included in the analysis. In general, the use of SNRIs was not associated with an increased risk of overall congenital malformations when compared with no exposure (rate ratio [RR] = 1.07, 95% confidence interval [CI] = 0.94-1.22; P = 0.31), exposure to SSRIs (RR = 1.12, 95% CI = 0.97-1.31; P = 0.12) and no exposure with clinical indication (RR = 1.04, 95% CI = 0.9-1.2; P = 0.564). A significantly increased risk of cardiac malformations was observed (RR = 1.33, 95% CI = 1.15-1.53; P < 0.001); however, this association was not statistically significant when the reference group comprised mothers exposed to SSRIs (RR = 1.1, 95% CI = 0.85-1.43; P = 0.47) or no exposure with clinical indication (RR = 1.17, 95% CI = 0.95-1.42; P = 0.13). The evidence shows no increased risk of congenital malformations and argues against a substantial cardiac teratogenic effect of SNRIs.

The role of fibrosis index FIB-4 in predicting liver fibrosis stage and clinical prognosis: A diagnostic or screening tool?

This review evaluates the ability of the fibrosis index based on four factors (FIB-4) identifying fibrosis stages, long-time prognosis in chronic liver disease, and short-time outcomes in acute liver injury. FIB-4 was accurate in predicting the absence or presence of advanced fibrosis with cut-offs of 1.0 and 2.65 for viral hepatitis B, 1.45 and 3.25 for viral hepatitis C, 1.30 (<65 years), 2.0 (≥65 years), and 2.67 for non-alcoholic fatty liver disease (NAFLD), respectively, but had a low-to-moderate accuracy in alcoholic liver disease (ALD) and autoimmune hepatitis. It performed better in excluding fibrosis, so we built an algorithm for identifying advanced fibrosis by combined methods and giving work-up and follow-up suggestions. High FIB-4 in viral hepatitis, NAFLD, and ALD was associated with significantly high hepatocellular carcinoma incidence and mortality. Additionally, FIB-4 showed the ability to predict high-risk varices with cut-offs of 2.87 and 3.91 in cirrhosis patients and predict long-term survival in hepatocellular carcinoma patients after hepatectomy. In acute liver injury caused by COVID-19, FIB-4 had a predictive value for mechanical ventilation and 30-day mortality. Finally, FIB-4 may act as a screening tool in the secondary prevention of NAFLD in the high-risk population.
