The aim of this study was to perform a systematic review of the use of the Live Birth Information System (Sistema de Informações de Nascidos Vivos--SINASC) in health research. MEDLINE, LILACS and SciELO databases were searched from 1994 to 2005 using the following combination of descriptors: "SINASC", "live birth", "Brazil". We identified 157 abstracts within the reference period, among which 44 were selected and classified according to specific criteria. The number of articles published per year increased during the period studied. The majority of the studies was carried out in the Southeast region and used the municipality as the geographic unity of analysis. A varied range of subjects were assessed including descriptions of live births profiles, health service and programs evaluations and risk factors for infant outcomes. In conclusion, although the SINASC represents an important data source for maternal-infant health research, the system's coverage and the reliability of its data need to be better evaluated.

Background: Cancer treatments such as chemotherapy and radiotherapy often compromise fertility by damaging gonadal function, creating a critical need for fertility preservation options. Despite advancements in fertility preservation techniques, there is a significant lack of research focused on their application in Asian cancer patients and their utilisation remains underexplored in this population.
Aim: This study aims to evaluate the utilisation rates and outcomes of cryopreserved gametes in cancer patients who underwent fertility preservation before their cancer treatment.

Objective: To determine the validity of a screening algorithm based on combination of clinical examination and pulse oximetry, for early detection of congenital heart disease (CHD) in term newborns. CHD is the most frequent major congenital anomaly, with prevalence of 6-12 per 1000 live births. Clinical examination alone may fail to detect CHD in more than 50% of affected newborns.

Purpose: Dyslipidemia has been linked to adverse pregnancy outcomes in observational studies. This study aimed to explore how variations in lipid levels during the first trimester might influence early pregnancy loss (EPL).
Methods: Blood samples from pregnant women were analyzed to examine the relationship between EPL and lipid metabolism using logistic regression and restricted cubic splines (RCS).

Background: Over the past decade, numerous studies have been conducted to determine the role of homocysteine and methylenetetrahydrofolate reductase () gene polymorphisms in the pathogenesis of polycystic ovary syndrome (PCOS), yet the results are inconsistent. The aim of the current study was to determine the association between homocysteine levels (Hcy), ) and A1298C polymorphisms, and pregnancy outcomes in Georgian women with PCOS.
Materials And Methods: This case-control study included 177 female participants, of which 96 women were diagnosed with PCOS, and 81 age-matched women were without PCOS.

Background: The effectiveness of changing the type of luteal phase support in patients with poor ovarian response (POR) remains unclear based on the available evidence. This study aimed to compare the effectiveness of various luteal phase support (LPS) methods, including progesterone alone, human chorionic gonadotropin (hCG) alone, and the combination of progesterone with hCG, in these patients.
Materials And Methods: In this randomized clinical trial, 375 patients diagnosed with POR based on the Bologna criteria underwent intracytoplasmic sperm injection-embryo transfer (ET) cycles at the Royan Institute between November 2015 and June 2019.
