Effectiveness of direct-acting antiviral drugs against hepatitis C virus: predictive factors of response to the treatment.
Background/Aims. Despite the high efficacy and safety of direct-acting antivirals against hepatitis C virus shown in clinical trials, treatment failures continue to occur. Our aim was to establish the effectiveness of these drugs in routine clinical practice, as well as to determine factors that could influence the response to the treatment. ⋯ Conclusion. The effectiveness and safety of direct-acting antivirals against hepatitis C virus have been maintained in routine clinical practice. Further research on predictive factors of response is required in order to develop more reliable and reproducible predictive models.

MicroRNAs (miRNAs) play an important role in the development of prostate cancer (PCa). Recent studies have shown that miR-92a expression is significantly increased in various cancers including PCa. However, its specific mechanism in PCa remains unknown. ⋯ In addition, the mRNA and protein levels of PTEN in PC-3 and LNCap cells in the miR-92a inhibitor group were significantly increased, while the phosphorylation levels of PI3K and AKT were significantly decreased. MiR-92a might play a key role in regulating the proliferation, migration and invasion of PCa cells through the PTEN/Akt signaling pathway. Inhibition of miR-92a expression has practical value against PCa and provides ideas for further clinical treatment of patients with PCa.

Background: TIMP3 is a multifunctional proteolytic enzyme belonging to TIMPs family and acts as a potent inhibitor of matrix metalloproteinases (MMPs). TIMP3 possesses a tumor suppresive function by directly promoting tumor cell apoptosis, preventing angiogenesis and extracellular matrix remodelling. The lower expression of TIMP3 was associated with poor prognosis and overall survival in various cancer types. ⋯ In fact, OC patients with high TIMP3 expression had longer survivals. Multivariate Cox's regression analysis suggests that low TIMP3 protein expression pattern is an independent poor survival marker (p = 0.025). Conclusion: Cytoplasmic TIMP3 protein expression could be used as a good prognosticator to stratify poorly prognostic OC patients in order to personlaize their disease management.

Background: The Mediterranean diet (MedDiet) is a dietary pattern effective in terms of prevention of many diseases such as gestational diabetes mellitus (GDM). Recently, many studies have paid attention to nutritional factors during pregnancy as a modifiable contributor to GDM risk. Objective: to investigate associations of nutrients intakes and MedDiet pattern of eating with risk of GDM. ⋯ GDM subjects consumed significantly more dairy products and cereals (P < 10-3). After adjustment for confounders, no nutrient was associated with the risk of developing gestational diabetes except vitamin D intake (OR 0.29 [0.15-0.54], P < 10-3) which had a protective effect. Conclusion: Our study underlines the importance of adequate vitamin D intake during pregnancy and suggests that the MedDiet may reduce the incidence of gestational diabetes.

The burdenofchildren with cardiovascular disease is on a rising trend. These rising trends are enhanced by the development of new technology in the diagnosis of cardiac lesions. This article is aimed at documenting the current trends in the occurrence of cardiac disease among children attending tertiary hospitals in Sothern Nigeria. ⋯ Five 62.5% (5/8) of such dysmorphic features were associated with VSD. The majority of the children with cardiac disease were from the middle class 63.6% followed by the higher class 21.9% and the least is from the lower class 14.5%. The prevalence values of heart disease were quite higher than that documented in previous studiesThe is a rising prevalence of congenital heart disease (83.6%) and acquired heart disease (16.4%) among children with cardiac disease in southern Nigeria. Extracardiac anomalies were also associated with these trends.
