RESUMEN
METHODS: This is a cohort study, conducted at a university-based reproductive medicine center and private reproductive medicine center that aimed to evaluate granulosa cumulus cell gene expression in the insulin signaling pathway in Polycystic Ovary Syndrome (PCOS) patients undergoing in vitro fertilization (IVF) treatment and to compare the cumulus gene expression between normal weight and obese women without clinical insulin resistance. Fifteen PCOS patients, nine normal weight patients and six obese patients presenting normal HOMA IR (Homeostasis Model Assessment-Insulin Resistance), participated. Patients underwent oocyte retrieval for IVF and after the procedure, granulosa cumulus cells were removed from the oocytes for RNA extraction. Quantitative polymerase chain reaction (PCR) array analysis of 84 genes from insulin signaling pathway was conducted. The results were expressed as fold up- or fold down-expression in obese patients compared with normal weight patients. Any fold change ⩾3 or ⩽3 and any p ⩽ 0.05 were considered statistically significant. RESULTS: There were 10 genes that were overexpressed in obese compared with normal weight women, BCL2L1, BRAF, CBL, DOK1, FBP1, FRS2, MTOR, PCK2, RPS6KA1, and SORBS1, that had a fold change ⩾3 and p ⩽ 0.05. DISCUSSION: In the obese group, the overexpressed genes are mainly responsible for the proliferation and differentiation of cumulus cells during oocyte maturation, insulin resistance, apoptosis regulation, and glucose metabolism during early embryogenesis, suggesting that in the follicular environment, insulin resistance is present even in the absence of clinical signs. CONCLUSION: Together, our findings and the related literature suggest that those alterations may be associated with the worse prognosis of follicular development and oocyte maturation observed in PCOS obese women.
RESUMEN
OBJECTIVE: To identify the main research interests of Brazilian patients in the field of infertility and assisted reproductive technology (ART) treatments. METHODS: This prospective multicenter cross-sectional study was carried out in Brazil. Patients attending five fertility centers from the Huntington Group between October and December 2018 were invited to join the study, which consisted of answering an anonymous survey online. Two hundred and twenty-seven patients signed the informed consent form and were emailed the survey link. The survey was designed based on the James Lind Alliance Priority Setting Partnership protocol. In the area of infertility, patients were probed on issues such as somatic and psychological effects of treatment, prevention, assisted reproductive technology (medications and procedures), success rates, risks, and emotional aspects. RESULTS: The response rate (RR) was 47.58% (108 patients; 88 women - RR 51.46% and 20 men - RR 35.71%). Patient mean age was 36.5 years (SD 4.6). The top ten research priorities listed were 1) short- and long-term side effects of treatment; 2) how to cope with infertility; 3) risks associated with ART; 4) success rates in ART; 5) impact of diet on ART and fertility; 6) healthy habits; 7) alternative therapies; 8) impact of exercise on fertility and ART success; 9) oocyte quality and ovarian reserve; and 10) genetic or inherited causes of infertility. CONCLUSION: To better cater to the needs of patients and develop patient-centered care in the field of infertility and ART treatment, clinicians, healthcare providers, and the scientific community must identify patient concerns and priorities and make efforts to address them.

OBJECTIVE: The aim of this study was to assess the knowledge about the risk of infertility in cancer patients after treatment, and the options for fertility preservation based on a survey carried out during the 2013 Pink October campaign. METHODS: This survey was carried out during the 2013 Pink October event in the most important public park of São Paulo, Brazil. Approximately 900 people expressed interest in learning about breast cancer prevention and fertility preservation by participating in workshops, and 242 people filled out a questionnaire. RESULTS: Most of the respondents (78.5%) were women, and one-fourth (25%) had at least one relative with gynecological cancer. Among women over 40 years of age, 86.3% had been screened for breast cancer at some point. However, few participants (34.0%) were aware that cancer treatment can lead to infertility or had heard about fertility preservation options (22.0%). Having a relative with cancer did not influence their knowledge about fertility preservation (22.4% versus 21.3%; p=0.864). However, a higher educational level was significantly associated with more knowledge about the effects of cancer on fertility and options for fertility preservation. CONCLUSIONS: The majority of participants did not have knowledge about the impact of oncologic treatment on fertility and did not know that there are options to preserve fertility in cancer patients. Awareness of infertility risk factors is an essential first step to safeguard future fertility, and therefore, more educational initiatives are needed to spread knowledge about oncofertility.
