background: There is evidence that intrauterine growth restriction, resulting in newborn girls that are small for gestational age (SGA), may be related to the onset of polycystic ovary syndrome (PCOS). Thus, we studied whether women born SGA have a higher prevalence of PCOS than women born appropriate for gestational age (AGA).methods: This was a prospective birth cohort study of 384 women born at term between June 1, 1978, and May 31, 1979, in Ribeirão Preto, Brazil. After exclusion, 165 women effectively participated in this study, of whom 43 were SGA and 122 were AGA. The prevalence of PCOS was analysed. At a mean age of 29 years, the women agreed to follow the study protocol, which included: anamnesis, physical examination, serum tests [follicle stimulating hormone, luteinizing hormone, total and free testosterone, dehydroepiandrostenedione sulphate, 17-OH-progesterone, fasting insulin, sex steroid-binding globulin (SHBG) and fasting glucose] and pelvic ultrasound. Data regarding gestational age, birthweight, age at menarche and maternal data were obtained from the files of the cohort. The adjusted relative risk (RR) values of the SGA, insulin resistance, body mass index, maternal smoking and parity variables were analysed using Poisson regression with robust adjustment of variance for the prediction of PCOS.results: The prevalence of PCOS was higher in the SGA group than in the AGA group [adjusted RR ¼ 2.44, 95% CI (1.39-4.28)].Hyperandrogenism was more prevalent in the SGA women than in the AGA women (P ¼ 0.011). Circulating SHBG was lower in the SGA women than in the AGA women (P ¼ 0.041), but fasting insulinemia was similar in both groups.conclusions: The prevalence of PCOS in SGA women was twice as high as in AGA women in our study population.

Background. Although chronic hyperandrogenism, a typical feature of polycystic ovary syndrome, is often associated with disturbed reproductive performance, androgens have been shown to promote ovarian follicle growth in shorter exposures. Here, we review the main effects of androgens on the regulation of early folliculogenesis and the potential of their application in improving follicular in vitro growth. Review. Androgens may affect folliculogenesis directly via androgen receptors (ARs) or indirectly through aromatization to estrogen. ARs are highly expressed in the granulosa and theca cells of early stage follicles and slightly expressed in mature follicles. Short-term androgen exposure augments FSH receptor expression in the granulosa cells of developing follicles and enhances the FSH-induced cAMP formation necessary for the transcription of genes involved in the control of follicular cell proliferation and differentiation. AR activation also increases insulin-like growth factor (IGF-1) and its receptor gene expression in the granulosa and theca cells of growing follicles and in the oocytes of primordial follicles, thus facilitating IGF-1 actions in both follicular recruitment and subsequent development. Conclusion. During the early and intermediate stages of follicular maturation, locally produced androgens facilitate the transition of follicles from the dormant to the growing pool as well as their further development.

RESUMO-As experiências inovadoras, direcionadas para as especificidades da atenção integral, da formação e da capacitação profissional na área das urgências, no Brasil, são recentes e vêm sofrendo influências dos modelos franco-germânico e anglo-americano. A incorporação do Sistema de Atendimento Móvel de Urgência (SAMU) e da Regulação Médica(RM) à rede assistencial, no País, iniciou-se a partir da cooperação franco-brasileira, em 1995. Em nosso meio, o SAMU foi implantado em 1996 e a RM de toda a demanda de urgência para os hospitais, no ano de 2000. A atenção inicial às urgências, no Brasil, tal como no modelo franco-germânico é multidisciplinar, mas a sistematização do conhecimento e a das práticas assistenciais das equipes de saúde para o suporte avançado à vida têm sido influenciadas pelos programas anglo-americanos, tais como o Advanced Cardiac Life Support, o Advanced Trauma Life Support, o Pediatric Advanced Life Support e o Basic Life Support, dentre outros. Essas estratégias, adaptadas à realidade brasileira, têm contribuído para a transformação do velho modelo de organização da atenção às urgências, bem como proporcionado revisões dos conteúdos curriculares e da organização acadêmica. Os problemas da atenção às urgências, nos grandes centros urbanos, e algumas experiências com êxito, no âmbito do Sistema Único de Saúde(SUS), subsidiaram a formulação da Politicas Nacional de Atenção às Urgências (PNAU) e de Humanização (PNH) do Ministério da Saúde. Ao Ministério da Educação, aos Centros Formadores, aos Conselhos de Classe e às Agências de Fomento à Pesquisa cabem, em sintonia com o SUS, a formulação dos padrões para a formação, o exercício profissional e a investigação na atenção às urgências. A Unidade de Emergência do HCFMRP-USP (UE-HC), nos últimos anos, aplicando conceitos contemplados pela PNAU e pela PNH, participou da configuração de uma rede assistencial regional, hierarquizada de atenção às urgências, regulada e humanizada por meio da implantação da RM e do SAMU. Os serviços clínicos da UE-HC, vinculados aos Departamentos de Aplicação da FMRP-USP e apoiados pelo Centro de Estudos de Emergências ajudaram a redefinir a missão assistencial e educacional da unidade. A superlotação foi equacionada com a redução significativa do número de consultas e da taxa de ocupação, e, como era esperado, houve aumento da média de permanência, da complexidade dos casos atendidos e do custo médio das internações.Assim, a UE-HC tem se transformado num centro de referência para a assistência de elevada complexidade, assim como para a formação e capacitação de profissionais que lidam com as urgências. Neste cenário, estão surgindo as possibilidades para a reflexão crítica das práticas já instituídas, a sistematização das práticas e do conhecimento, a preparação para a produção de novos saberes e as bases para a criação de um departamento acadêmico e da especialidade de Urgências Médicas UNITERMOS-Emergência.

Introduction There is a need for specific measures to address overall care in women with polycystic ovary syndrome (PCOS). Physical resistance training (PRT) has been shown to improve certain body parameters. However, the effect of PRT on the sexual function of PCOS women has not been evaluated. Aim The study aimed to assess sexual function and emotional status of PCOS women after 16 weeks of PRT. Methods This case-control study involved 43 women with PCOS and 51 control ovulatory women, aged 18–37 years. All women were subjected to a supervised PRT protocol for 16 weeks and evaluated at the end of the program. Sexual function was assessed at baseline and after PRT protocol. Main Outcome Measures The main outcome measure used was the Female Sexual Function Index (FSFI). Results Of the 43 women with PCOS, 30 (69.70%) had a basal total FSFI score ≤ 26.55 and 24 of them (58.54%) had a score ≤ 26.55 after PRT (P = 0.08). Of the 51 control women, 32 (62.7%) and 27 (52.9%) had FSFI scores < 26.55 at baseline and after PRT, respectively (P = 0.06). Control women experienced a significant improvement in pain domain score after PRT (P < 0.03). PCOS women experienced significant increases in total score and in the desire, excitement and lubrication domains after PRT (P < 0.01 each). After PRT, there was a significant difference between the PCOS and control groups in the sexual desire domain (4.09 ± 1.29 vs. 3.75 ± 1.42, P = 0.04). Significantly fewer women in the PCOS group were at risk of depression (P < 0.01) and anxiety (P < 0.02) after than before PRT, whereas the differences in the control group were not significant. Mean depression and anxiety scores were reduced significantly in both the PCOS (P < 0.01 each) and control (P < 0.01) groups. Conclusions PRT significantly enhanced total score and the desire, excitement, and lubrication domains of the FSFI in PCOS women. PRT reduced pain, and total depression and anxiety scores in both groups.

Young women with PCOS exhibit changes in vascular elasticity even in the absence of classical risk factors for CVD, such as hypertension and obesity.

The aim of the present study was to compare the modulation of heart rate in a group of postmenopausal women to that of a group of young women under resting conditions on the basis of R-R interval variability. Ten healthy postmenopausal women (mean ± SD, 58.3 ± 6.8 years) and 10 healthy young women (mean ± SD, 21.6 ± 0.82 years) were submitted to a control resting electrocardiogram (ECG) in the supine and sitting positions over a period of 6 min. The ECG was obtained from a one-channel heart monitor at the CM5 lead and processed and stored using an analog to digital converter connected to a microcomputer. R-R intervals were calculated on a beat-to-beat basis from the ECG recording in real time using a signal-processing software. Heart rate variability (HRV) was expressed as standard deviation (RMSM) and mean square root (RMSSD). In the supine position, the postmenopausal group showed significantly lower (P<0.05) median values of RMSM (34.9) and RMSSD (22.32) than the young group (RMSM: 62.11 and RMSSD: 49.1). The same occurred in the sitting position (RMSM: 33.0 and RMSSD: 18.9 compared to RMSM: 57.6 and RMSSD: 42.8 for the young group). These results indicate a decrease in parasympathetic modulation in postmenopausal women compared to young women which was possibly due both to the influence of age and hormonal factors. Thus, time domain HRV proved to be a noninvasive and sensitive method for the identification of changes in autonomic modulation of the sinus node in postmenopausal women.

From the discovery of the Zika virus (ZIKV) in 1947 in Uganda (Africa), until its arrival in South America, it was not known that it would affect human reproductive life so severely. Today, damage to the central nervous system is known to be multiple, and microcephaly is considered the tip of the iceberg. Microcephaly actually represents the epilogue of this infection's devastating process on the central nervous system of embryos and fetuses. As a result of central nervous system aggression by the ZIKV, this infection brings the possibility of arthrogryposis, dysphagia, deafness and visual impairment. All of these changes of varying severity directly or indirectly compromise the future life of these children, and are already considered a congenital syndrome linked to the ZIKV. Diagnosis is one of the main difficulties in the approach of this infection. Considering the clinical part, it has manifestations common to infections by the dengue virus and the chikungunya fever, varying only in subjective intensities. conjunctivitis and arthralgia, among others. In terms of laboratory resources, there are also limitations to the subsidiary diagnosis. Molecular biology tests are based on polymerase chain reaction (PCR) with reverse transcriptase (RT) action, since the ZIKV is a ribonucleic acid (RNA) virus. The RT-PCR shows serum or plasma positivity for a short period of time, no more than five days after the onset of the signs and symptoms. The ZIKV urine test is positive for a longer period, up to 14 days. There are still no reliable techniques for the serological diagnosis of this infection. If there are no complications (meningoencephalitis or Guillain-Barré syndrome), further examination is unnecessary to assess systemic impairment. However, evidence is needed to rule out other infections that also cause rashes, such as dengue, chikungunya, syphilis, toxoplasmosis, cytomegalovirus, rubella, and herpes. There is no specific antiviral therapy against ZIKV, and the therapeutic approach to infected pregnant women is limited to the use of antipyretics and analgesics. Anti-inflammatory drugs should be avoided until the diagnosis of dengue is discarded. There is no need to modify the schedule of prenatal visits for pregnant women infected by ZIKV, but it is necessary to guarantee three ultrasound examinations during pregnancy for low-risk pregnancies, and monthly for pregnant women with confirmed ZIKV infection. Vaginal delivery and natural breastfeeding are advised.
