Question: Context: To assess the relationship between congenital uterine malformations and blood pressure in pregnancy.', 'Twenty-four-hour automated ambulatory blood pressure monitoring (readings every 30 min) was performed in 16 normotensive, nonproteinuric, primigravidae with congenital uterine malformations (5 uterus septus, 9 uterus bicornis, 2 uterine didelphys) between 20 and 30 weeks. From the 24-hr blood pressure report, we calculated 24-hr mean, daytime and nighttime means. The results were compared with 16 primigravidae, matched for age and gestation, who were and remained normotensive throughout pregnancy, and tested for statistics with t-test; significance assessed at p < 0.001.', 'Although they were within the normotensive range, all blood pressure measurements considered were significantly higher in pregnant women with congenital uterine malformations, compared to normal pregnant women. Namely, 24-hr, daytime, and nighttime systolic (mean +/- SD) were 121.1 +/- 8.4, 124.4 +/- 8.8, 114.0 +/- 7.7 mmHg, respectively, in women with uterine malformations and 108.0 +/- 7.4, 109.2 +/- 7.3, 102.1 +/- 8.5 mmHg, respectively, in normal pregnant women. Twenty-four-hour diastolic, daytime, and nighttime diastolic (mean +/- SD) 74.1 +/- 10.2, 77.1 +/- 10.6, 68.1 +/- 9.2 mmHg, in women with uterine malformations and 64.1 +/- 5.7, 66.0 +/- 5.7, 58.2 +/- 6.3 mmHg, in normal pregnant women (all differences p < 0.001). Fifteen of the fetuses from women with congenital uterine malformations showed intrauterine growth retardation. No differences were found 6 months after delivery.\Question: Are congenital uterine malformations associated to increased blood pressure in pregnancy?

Answer: Although the blood pressure levels remained within the normotensive range, pregnant women with congenital uterine anomalies have a higher blood pressure than normal women. Elevated blood pressure can result from altered uterine circulation and reduced blood supply to the placenta. This pathogenesis or the poor placentation may result in a foetal growth retardation.


Question: Context: Physical inactivity has been associated with obesity and related chronic diseases. Understanding built environment (BE) influences on specific domains of physical activity (PA) around homes and workplaces is important for public health interventions to increase population PA.', 'To examine the association of home and workplace BE features with PA occurring across specific life domains (work, leisure, and travel).', 'Between 2012 and 2013, telephone interviews were conducted with participants in four Missouri metropolitan areas. Questions included sociodemographic characteristics, home and workplace supports for PA, and dietary behaviors. Data analysis was conducted in 2013; logistic regression was used to examine associations between BE features and domain-specific PA.', "In home neighborhoods, seven of 12 BE features (availability of fruits and vegetables, presence of shops and stores, bike facilities, recreation facilities, crime rate, seeing others active, and interesting things) were associated with leisure PA. The global average score of home neighborhood BE features was associated with greater odds of travel PA (AOR=1.99, 95% CI=1.46, 2.72); leisure PA (AOR=1.84, 95% CI=1.44, 2.34); and total PA (AOR=1.41, 95% CI=1.04, 1.92). Associations between workplace neighborhoods' BE features and workplace PA were small but in the expected direction.\Question: Does home and workplace built environment support for physical activity?

Answer: This study offers empirical evidence on BE supports for domain-specific PA. Findings suggest that diverse, attractive, and walkable neighborhoods around workplaces support walking, bicycling, and use of public transit. Public health practitioners, researchers, and worksite leaders could benefit by utilizing worksite domains and measures from this study for future BE assessments.


Question: Context: CD100, also known as Sema4D, is a member of the semaphorin family and has important regulatory functions that promote immune cell activation and responses. The role of CD100 expression on B cells in immune regulation during chronic hepatitis C virus (HCV) infection remains unclear.', 'We longitudinally investigated the altered expression of CD100, its receptor CD72, and other activation markers CD69 and CD86 on B cells in 20 chronic HCV-infected patients before and after treatment with pegylated interferon-alpha (Peg-IFN-α) and ribavirin (RBV) by flow cytometry.', 'The frequency of CD5+ B cells as well as the expression levels of CD100, CD69 and CD86 was significantly increased in chronic HCV patients and returned to normal in patients with sustained virological response after discontinuation of IFN-α/RBV therapy. Upon IFN-α treatment, CD100 expression on B cells and the two subsets was further up-regulated in patients who achieved early virological response, and this was confirmed by in vitro experiments. Moreover, the increased CD100 expression via IFN-α was inversely correlated with the decline of the HCV-RNA titer during early-phase treatment.\Question: Is cD100 up-regulation induced by interferon-α on B cells related to hepatitis C virus infection?

Answer:
Peripheral B cells show an activated phenotype during chronic HCV infection. Moreover, IFN-α therapy facilitates the reversion of disrupted B cell homeostasis, and up-regulated expression of CD100 may be indirectly related to HCV clearance.
