Antimüllerian hormone levels and IVF outcomes in polycystic ovary syndrome women: a scoping review.

Antimüllerian hormone (AMH) is a homodimeric glycoprotein secreted by granulosa cells from primary to large antral follicles, and it plays an important role in the regulation of early follicle growth. It is considered a reliable marker of ovarian reserve and a predictor of ovarian response to controlled stimulation. Polycystic ovary syndrome (PCOS) is an endocrine condition that affects women of reproductive age worldwide, and it is associated with high levels of AMH. PCOS patients may have worse maturation and fertilization rates compared to normo-ovulatory women. Some studies have demonstrated a positive correlation between AMH levels and qualitative aspects of assisted reproduction treatment; but it is not clear whether high levels of both serum and follicular fluid AMH in PCOS patients correlate with in vitro fertilization outcomes. We ran this scoping review of the literature to address this specific question. We comprehensively searched the databases PubMed and Cochrane Library until January 2023. We found that higher AMH levels are associated with higher oocyte yield, but PCOS patients tend to have fewer mature oocytes and impaired embryo quality and implantation rates. Pregnancy rates, however, are not affected by AMH levels or laboratorial outcomes. We also found that higher AMH levels are associated with worse PCOS features.

Hipertensão arterial na cidade de São Paulo: prevalência referida por contato telefônico / Hypertension in the city of São Paulo: self-reported prevalence assessed by telephone surveys

FUNDAMENTO: Pouco se conhece sobre a prevalência da hipertensão arterial na cidade de São Paulo, SP, Brasil. OBJETIVO: Identificar a prevalência da hipertensão referida na cidade de São Paulo. MÉTODOS: Realizaram-se 613 entrevistas por telefone, a partir das listas residenciais do sistema de telefonia fixa. A amostra foi calculada com prevalência estimada de hipertensão em 20,0 por cento. RESULTADOS: A prevalência referida de hipertensão foi de 23,0 por cento e 9,0 por cento dos entrevistados referiram que o valor de sua última medida da pressão foi maior que 140/90 mmHg, porém não tinham conhecimento de que eram hipertensos, totalizando uma prevalência de 32,0 por cento. Os hipertensos referiram que: 89,0 por cento fazem tratamento e 35,2 por cento estavam controlados; 27,0 por cento faltam às consultas; 16,2 por cento deixam de tomar os remédios; 14,8 por cento apresentam história de acidente vascular encefálico, 27,8 por cento cardiopatia e 38,7 por cento hipercolesterolemia; 71,2 por cento receberam orientação para diminuir sal, 64,6 por cento para realizar atividade física, 60,0 por cento para perder peso e 26,2 por cento para controlar estresse; e 78,9 por cento mediam a pressão regularmente. Houve relação estatisticamente significante (p < 0,05) para: 1) faltar às consultas com maior tempo de tratamento e acompanhamento irregular de saúde; 2) deixar de tomar os remédios com tabagismo, etilismo e a não realização de acompanhamento de saúde; 3) realizar tratamento para hipertensão com dislipidemia, idade mais elevada e maior tempo de uso de anticoncepcional, no caso das mulheres; e 4) índice de massa corporal alterado com presença de diabete, hipercolesterolemia, pressão sistólica não controlada e uso de mais de um anti-hipertensivo. CONCLUSÃO: A prevalência referida de hipertensão na cidade de São Paulo assemelha-se à prevalência identificada em outros estudos.

BACKGROUND: Little is known about the prevalence of hypertension in São Paulo, Brazil. OBJECTIVE: To identify the prevalence of self-reported hypertension in the city of São Paulo. METHODS: There were 613 telephone interviews using directories of household landlines. The sample was calculated with an estimated prevalence of hypertension in 20.0 percent. RESULTS: The prevalence of self-reported hypertension was 23.0 percent and 9.0 percent of respondents reported that the value of their last pressure measurement was greater than 140/90 mmHg, but they were unaware that they were hypertensive, with a total prevalence 32.0 percent. Hypertensive patients reported that: 89.0 percent were under treatment and 35.2 percent were controlled; 27.0 percent miss medical appointments; 16.2 percent stop taking drugs; 14.8 percent have a history of stroke; 27.8 percent had heart disease and 38.7 percent had hypercholesterolemia; 71.2 percent received advice to reduce salt, 64.6 percent to perform physical activity, 60.0 percent to lose weight loss and 26.2 percent to control stress; and 78.9 percent measured pressure regularly. There was a statistically significant relation (p < 0.05) for: 1) missing medical appointments with longer treatment and irregular health monitoring; 2) stop taking the drugs with smoking, alcohol and failure to monitore health; 3) carry out treatment for hypertension with dyslipidemia, higher age and longer use of contraceptives for women; and 4) body mass index changed with diabetes, hypercholesterolemia, uncontrolled systolic blood pressure and use of more than one anti-hypertension drug. CONCLUSION: The prevalence of self-reported hypertension in the city of São Paulo resembles the prevalence found in other studies.
