Methods: The systematic review contemplated the Scopus, Embase, Pubmed, Scielo and Lilacs data bases. The inclusion criteria were epidemiological quantitative, observational, descriptive and analytical studies that had as target public children contemplated by the income transfer program with health conditionalities in Latin America. Narrative reviews related to the research theme were excluded as well as systematic reviews with or without meta-analysis related to the research theme. Results: The titles and abridgements review from 1007 articles resulted in the selection of 17 complete studies. After the quality analysis of these, as well as the application of the inclusion criteria, 10 articles were included in this review. Among the types of epidemiologic studies selected to compose this systematic review, 3 are cohort analytical studies. Conclusion: Studies carried out in Brazil, Mexico, Ecuador and Nicaragua were selected and indicated the positive effects that the conditional income transfer brought to the anthropometric index from beneficiary children in the researched countries.展开更多

The temperatures involved are assumed to be very high so that the radiative heat transfer is significant, which renders the problem highly non-linear even with the assumption of a differential approximation for the radiative heat flux. A numerical method based on the Nakamura scheme has been employed to obtain the temperature and velocity distributions which are depicted graphically. The effects of the different parameters entering into the problem have been discussed extensively.展开更多

Methods: A retrospective analysis of the complete clinical data of 340 patients undergoing in vitro fertilization embryo transfer in the Department of Reproductive Medicine, Jingzhou Central Hospital from September 2016 to July 2018. These patients were divided into group A and B according to the luteal support program. We compared the clinical outcomes of the two corpus luteum preparations by comparing the laboratory parameters of the two groups of patients with clinical pregnancy indicators. Results: We found there was no significant difference in the results of general conditions in the two groups of patients, such as infertility age and duration, body mass index (BMI), basal follicle stimulating hormone (FSH), basal luteinizing hormone (LH), basal estrogen (E2) levels, the endometrial thickness, the number of transplanted high-quality embryos on the day of transplantation and so on (P > 0.05). We found that the implantation rate (32.55%), biochemical pregnancy rate (53.57%), and clinical pregnancy rate (51.78%) in group B were significantly higher than those in group A (25.26%, 35.11%, and 34.66%, respectively) (P 0.05). Conclusion: We conclude that patients who are scheduled for frozen embryo transfer use progesterone vaginal sustained release capsules combined with luteal progesterone luteal support, have improved clinical pregnancy rates.展开更多
