To investigate in the literature the studies on the benefits ofmusic therapy interventions among pregnant women in the prenatal, delivery and postpartum periods.
The search for articles was carried out in the following electronic databases: VHL, LILACS, SciELO, Portal CAPES, PsycINFO, ERIC, PubMed/Medline, and journals specialized in this field: Revista Brasileira de Musicoterapia (“Brazilian Journal of Music Therapy”) and Voices.
Descriptors in Portuguese (musicoterapia, gravidez, gestantes, revisão), English (music therapy, pregnancy, pregnant women, review) and Spanish (musicoterapia, embarazo, mujeres embarazadas, revisión) were used. The search was delimited between January 2009 and June 2019. The process of selection and evaluation of the articles was performed through peer review.
n The following data were extracted: article title, year of publication, journal, author(s), database, country and date of collection, purpose of the study, sample size, type of care, intervention, instruments used, results, and conclusion. The data were organized in chronological order based on the year of publication of thestudy.
In total, 146 articles were identified, and only 23 studies were included in this systematic review. The articles found indicate among their results relaxation, decreased levels of anxiety, psychosocial stress and depression, decreased pain, increase in the maternal bond, improvement in the quality of sleep, control of the fetal heart rate and maternal blood pressure, and decreased intake of drugs in the postoperative period.
Music therapy during the prenatal, delivery and postpartum periods can provide benefits to pregnant women and newborns, thus justifying its importance in this field.

The process of ovulation involves multiple and iterrelated genetic, biochemical, and morphological events: cessation of the proliferation of granulosa cells, resumption of oocyte meiosis, expansion of cumulus cell-oocyte complexes, digestion of the follicle wall, and extrusion of the metaphase-II oocyte. The present narrative review examines these interrelated steps in detail. The combined or isolated roles of the folliclestimulating hormone (FSH) and luteinizing hormone (LH) are highlighted. Genes indiced by the FSH genes are relevant in the cumulus expansion, and LH-induced genes are critical for the resumption ofmeiosis and digestion of the follicle wall. A nonhuman model for follicle-wall digestion and oocyte release was provided.

Placental pathophysiology in SARS-CoV-2 infection can help researchers understand more about the infection and its impact on thematernal/neonatal outcomes. This brief review provides an overview about some aspects of the placental pathology in SARSCoV- 2 infection. In total, 11 papers were included. The current literature suggests that there are no specific histopathological characteristics in the placenta related to SARSCoV- 2 infection, but placentas frominfected women aremore likely to show findings of maternal and/or fetal malperfusion. The most common findings in placentas from infected women were fibrin deposition and intense recruitment of inflammatory infiltrates. The transplacental transmission of this virus is unlikely to occur, probably due to low expression of the receptor for SARS-CoV-2 in placental cell types. Further studies are needed to improve our knowledge about the interaction between the virus and the mother-fetus dyad and the impact on maternal and neonatal/fetal outcomes.

Scientific information on the impact of the new coronavirus (SARS-CoV-2) on the health of pregnant women, fetuses and newborns is considered of limited confidence, lacking good-quality evidence, and drawing biased conclusions. As a matter of fact, the initial impressions that the evolution of COVID-19 was no different between pregnant and non-pregnant women, and that SARS-CoV-2 was not vertically transmitted, are confronted by the documentation of worsening of the disease during pregnancy, poor obstetric outcomes, and the possibility of vertical transmission. The present article aims to compile the data available on the association of COVID-19 and reproductive events, from conception to birth.

Hydrosalpinx is a disease characterized by the obstruction of the salpinx, with progressive accumulation in the shape of a fluid-filled sac at the distal part of the tuba uterina, and closed to the ovary. Women with hydrosalpinges have lower implantation and pregnancy rates due to a combination of mechanical and chemical factors thought to disrupt the endometrial environment. Evidence suggests that the presence of hydrosalpinx reduces the rate of pregnancy with assisted reproductive technology. The main aim of the present is review to make an overview of the possible effects of hydrosalpinx on in vitro fertilization (IVF).We conducted a literature search on the PubMed, Ovid MEDLINE, and Google Scholar data bases regarding hydrosalpinx and IVF outcomes. Hydrosalpinx probably has a direct toxic effect on sperm motility and on the embryos. In addition, the increasing liquid inside the salpinges could alter the mechanisms of endometrial receptivity. The window of endometrial receptivity is essential in the implantation of blastocysts, and it triggers multiple reactions arising from the endometrium as well as the blastocysts. Hydrosalpinx could influence the expression of homeobox A10 (HOXA10) gene, which plays an essential role in directing embryonic development and implantation. Salpingectomy restores the endometrial expression of HOXA10; therefore, it may be one mechanism by which tubal

Thyroid diseases are relatively common in women in the reproductive period. It is currently understood that clinically-evident thyroid disorders may impair ovulation and, consequently, fertility. However, to date it has not been proven that high serum levels of thyroid-stimulating hormone and/or positivity for antithyroid antibodies are associated to a reduction in fertility, mainly in the absence of altered thyroxine levels. The present comprehensive review aims to present current data on the association between subclinical hypothyroidism and/or thyroid autoimmunity and reproductive outcomes.

Thrombocytopenia, defined as platelet count < 150,000mm3, is frequently diagnosed by obstetricians since this parameter is included in routine surveillance during pregnancy, with an incidence of between 7 and 12%. Therefore, decisions regarding subsequent examination and management are primordial. While most of the cases are due to physiological changes, as gestational thrombocytopenia, other causes can be related to severe conditions that can lead to fetal or maternal death. Differentiating these conditions might be challenging: they can be pregnancy-specific (pre-eclampsia/ HELLP syndrome [hemolysis, elevated liver enzymes, low platelets]), or not (immune thrombocytopenia purpura, thrombotic thrombocytopenic purpura or hemolytic uremic syndrome). Understanding the mechanisms and recognition of symptoms and signs is essential to decide an adequate line of investigation. The severity of thrombocytopenia, its etiology and gestational age dictates different treatment regimens.

Gonadotropin-releasing hormone analogues (GnRH-a) have been used preoperatively before hysteroscopic myomectomy to decrease the size and vascularization of the myomas, but evidence to support this practice is weak. Our objective was to analyze the use of GnRH-a in the reduction of submucous fibroid as a facilitator for surgical hysteroscopy from published clinical trials.
Studies from electronic databases (Pubmed, Scielo, EMBASE, Scopus, PROSPERO), published between 1980 and December 2018. The keywords used were fibroid, GnRH analogue, submucous, histeroscopy, histeroscopic resection and their correspondents in Portuguese.
The inclusion criteria were controlled trials that evaluated the GnRH-a treatment before hysteroscopic resection of submucous myomas. Four clinical trials were included in the meta-analysis.
Two review authors extracted the data without modification of the original data, using the agreed form. We resolved discrepancies through discussion or, if required, we consulted a third person.
The present meta-analysis included a total of 213 women and showed no statistically significant differences in the use of GnRH-a compared with the control group for complete resection of submucous myoma (relative risk [RR]: 0.94; 95%; confidence interval [CI]: 0.80-1.11); operative time (mean difference [MD]: - 3.81; 95%;CI : - 3.81-2.13); fluid absorption (MD: - 65.90; 95%;CI: - 9.75-2.13); or complications (RR 0.92; 95%;CI: 0.18-4.82).
The present review did not support the routine preoperative use of GnRH-a prior to hysteroscopic myomectomy. However, it is not possible to determine its inferiority when compared with the other methods due to the heterogeneity of existing studies and the small sample size.
