Impact of Physical Resistance Training on the Sexual Function of Women with Polycystic Ovary Syndrome.

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.

The effects of aerobic physical exercises on body image among women with polycystic ovary syndrome.

BACKGROUND: Both physical and mental health care for women with polycystic ovary syndrome (PCOS) require a multidisciplinary approach. We evaluated the effects of continuous (CAT) and intermittent (IAT) aerobic training in different protocols that measure body image, anxiety, depression and sexual dysfunction in women with PCOS. METHODS: In this controlled clinical trial, women with PCOS were randomly allocated for 16 weeks to 1 out of 3 groups: CAT (n = 28), IAT (n = 29), or control group (CG, n = 30). For data collection, we used the Body Shape Questionnaire (BSQ), Figure Rating Scale (FRS), Female Sexual Function Index (FSFI), Hospital Anxiety and Depression Measurement Scales (HADS). RESULTS: No effects of CAT, IAT or CG groups were identified in the perceptual dimension of body image. The dis(satisfaction) grade improved after exercise in the CAT group (p ≤ 0.01) compared to the CG, as well as improved within CAT and IAT groups. Total FSFI, and HADS-A and HADS-D scores improved after exercise in the both groups. At baseline and after the study period, there were positive correlations between scores for dis(satisfaction), HADS-A and HADS-D scores. HADS-A and HADS-D scores had a negative correlation with FSFI total in the IAT (p = =0.02) group compared to the CG, as well as within CAT and IAT groups. LIMITATIONS: The participants were not matched for body mass index (normal, overweight and obese) which may interfere on body image dimensions. CONCLUSION: Aerobic exercise improves sexual function and indices related to anxiety and depression. Likewise, it interferes in cognitive-affective dimension of the body image.

Increased arterial stiffness in nonobese women with polycystic ovary syndrome (PCOS) without comorbidities: one more characteristic inherent to the syndrome?

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with adverse metabolic effects. Some cardiovascular disease (CVD) risk markers are increased in women with PCOS. However, early markers of atherosclerosis are also associated with obesity and insulin resistance, which are related to PCOS. These markers may result either directly from PCOS or indirectly as a consequence of the comorbidities associated with the syndrome. CONTEXT: To assess the presence of early CVD markers in young, nonobese women with PCOS. PATIENTS: Forty women with PCOS and 50 healthy women with regular menstrual cycles, matched for age and body mass index (BMI). MEASUREMENTS: The following CVD markers were assessed by ultrasonography: common carotid artery (CCA) stiffness index (beta), distensibility and intima-media thickness (IMT), and brachial artery flow-mediated dilatation (FMD). Inflammatory markers, including interleukin (IL)-6, tumour necrosis factor (TNF)-alpha, homocysteine, C-reactive protein (CRP), glycaemia, lipid profile and insulin, were also assessed. RESULTS: CCA beta was higher in PCOS than in control women (3.72 +/- 0.96 vs. 3.36 +/- 0.96, P = 0.04) and CCA distensibility was lower (0.31 +/- 0.08 vs. 0.35 +/- 0.09 mmHg(-1), P = 0.02). Waist circumference, total testosterone and the Free Androgen Index (FAI) were higher in PCOS patients than in controls (78.2 +/- 10.0 vs. 71.5 +/- 7.2 cm, P = 0.001; 88.1 +/- 32.4 vs. 57.1 +/- 21.2 ng/dl, P < 0.01; 12.7 +/- 15.7%vs. 4.7 +/- 2.3%, P < 0.01, respectively), while SHBG was reduced (37.9 +/- 19.1 vs. 47.8 +/- 18.3 nmol/l, P = 0.01). The remaining variables did not differ between the groups. CONCLUSIONS: Young women with PCOS exhibit changes in vascular elasticity even in the absence of classical risk factors for CVD, such as hypertension and obesity.

Menopause leading to increased vaginal wall thickness in women with genital prolapse: impact on sexual response.

INTRODUCTION: Hypoestrogenism causes structural changes in the vaginal wall that can lead to sexual dysfunction. A reduction in vaginal wall thickness has been reported to occur after menopause, although without precise morphometry. AIM: To measure vaginal wall thickness in women with genital prolapse in normal and hypoestrogenic conditions and to correlate sexual dysfunction with vaginal wall thickness and estradiol levels. METHODS: Surgical vaginal specimens from 18 normoestrogenic and 13 postmenopausal women submitted to surgery for genital prolapse grades I and II were examined. Patients were evaluated for FSH, estradiol, prolactin, glycemia, and serum TSH levels. For histological analysis, samples were stained with Masson's trichrome and hematoxylin-eosin. Sexual function was assessed by the Golombok-Rust Inventory of Sexual Satisfaction (GRISS). MAIN OUTCOME MEASURES: GRISS questionnaire, histological analysis, morphometric methods, Masson's trichrome. RESULTS: The vaginal wall was thicker in the postmenopausal than premenopausal group (2.72 +/- 0.72 mm and 2.16 +/- 0.43, P = 0.01, and 2.63 +/- 0.71 mm and 2.07 +/- 0.49 mm, P = 0.01, for the anterior and posterior walls, respectively). These thicknesses seem to be due to the muscular layer, which was also thicker in the postmenopausal group (1.54 +/- 0.44 and 1.09 +/- 0.3 mm, P = 0.02, and 1.45 +/- 0.47 and 1.07 +/- 0.44 mm, P = 0.03, for the anterior and posterior wall, respectively). The vaginal epithelium was thinner in the middle segment than in the proximal one in the posterior wall (0.17 +/- 0.07 mm, 0.15 +/- 0.05 mm, 0.24 +/- 0.09 mm, P = 0.02). There was no correlation between coital pain, vaginal wall thickness, and estradiol levels in either group. CONCLUSION: The vaginal wall is thicker after menopause in women with genital prolapse. In this study, vaginal thickness and estrogen levels were not related to sexual dysfunction.

Withdrawal of plasma estradiol is associated with increased anxiety reported by women in the first 12 hours after delivery.

The aim of this study was to verify if the fall of plasma concentrations of steroid hormones in the first 12 h postpartum would be associated with changes in the same period in the emotional state of healthy women. Subjective and hormonal data were collected from 14 women (28.5 ± 7.1 years old) at zero (only hormones), 1, 2, 6 and 12 h after delivery. Subjective measures were taken using the Visual Analogue Mood Scale (VAMS), which consists of four factors (anxiety, sedation, discomfort, and cognitive impairment). Cortisol was measured by radioimmunoassay and estradiol and progesterone by chemiluminescence immunoassay. Women reported a significant increase in anxiety (relative increase: 43.8%±77.6) and discomfort (125.9%±218.5) within the 12 h postpartum. There were also significant decreases in the plasma concentration of estradiol (relative decrease: 96.5%±3.1), progesterone (78.1%±8.7) and cortisol (71.7%±18.0). The relative decrease in estradiol concentrations was significantly correlated with the relative increase in anxiety. No significant associations between progesterone and cortisol concentrations and subjective measures were observed. Changes of estradiol but not of progesterone and cortisol concentrations were associated with changes in the reported emotional state of healthy women in the immediate postpartum period. The role of this association as a predictor of mood disorders in the postpartum period should be explored in further studies.

Body image and its relationships with sexual functioning, anxiety, and depression in women with polycystic ovary syndrome.

BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with lower levels of satisfaction with body image, which can affect sexuality and social well-being. Thus, we evaluated body image in women with PCOS and its association with body dis(satisfaction), anthropometric indices, sexual function, anxiety, and depression. METHODS: In this cross-sectional study, 94 women of reproductive age were grouped by body mass index (BMI) and sexual function. The Female Sexual Function Index (FSFI), Body Shape Questionnaire (BSQ), Figure Rating Scale (FRS), hospital anxiety (HADS-A) and depression (HADS-D) measurement scales, and anthropometric indices were used for data collection. RESULTS: Women with PCOS presented with perceptual distortions of self-image independent of sexual function and BMI. There were negative correlations between HADS-A and HADS-D scores and the FSFI total score, and HADS-D scores had positive correlations with weight, anthropometric indices, and BSQ total score. The degree of dis(satisfaction) was a predictor of FSFI total score, depression, and anxiety, and the FSFI total score was predicted by HADS-D. Desired and ideal-gender BMIs were risk factors for sexual dysfunction, and overweight and obesity were risk factors for the degree of dis(satisfaction). LIMITATIONS: This study had the limitations of using a cross-sectional design and it investigated a restricted number of clinical/biochemical parameters, as well as lacked objective measures of acne and hirsutism, and a control group. CONCLUSIONS: Perception and cognitive-affective dimensions appear to play important roles in body image dysfunction in women with PCOS, and impact sexual dysfunction and depression associated the syndrome. Furthermore, these results provide additional treatment considerations for women with PCOS.

Interrupção legal da gravidez em crianças: o melhor interesse da gestante nas veredas do direito, da medicina e da ética / Legal termination of pregnancy in children in Brazil: the principle of the best interests of the child in the paths of law, medicine, and ethics / Interrupción legal del embarazo en niñas em Brasil: el principio del interés superior del niño en los caminos del derecho, la medicina y la ética

Objetivo: analisar o direito à interrupção legal da gravidez sob o marco teórico do princípio do melhor interesse da criança. Dentre os objetivos específicos, busca-se analisar a postura do Judiciário e do Ministério Público nos casos apresentados, os fundamentos jurídicos para o exercício do direito ao aborto em casos de estupro de vulnerável, os contornos teóricos do princípio do melhor interesse da criança, além de aspectos médicos, tais como a (in)existência de marco temporal para a interrupção da gravidez nos casos permitidos pela legislação, bem como a (im)possibilidade do exercício da objeção de consciência por médicos nesse contexto. Metodologia: adota-se a vertente jurídico-sociológica e a investigação jurídico-propositiva, por meio de raciocínio indutivo. Utiliza-se análise documental e bibliográfica, por meio de revisão bibliográfica qualitativa. Parte-se do marco teórico do princípio do melhor interesse da criança e do adolescente, previsto na Lei nº 8.069/1990, para testar a hipótese de que a interrupção legal da gravidez deve ser compreendida prima facie como o curso de ação que melhor se adequa ao princípio do melhor interesse da criança. Resultados: a gravidez em criança, por si só, já configura a violação de um direito fundamental. A interrupção da gestação nos casos de estupro de vulnerável é direito fundamental, garantido expressamente por lei, sem qualquer condicionante temporal ou qualitativa. Conclusão: confirmou-se a hipótese de que a interrupção legal da gravidez deve ser compreendida prima facie como o curso de ação que melhor se enquadra ao princípio do melhor interesse da criança.

Objective: to analyze the right to legal abortion within the theoretical framework of the principle of the best interests of the child. The specific objectives are to analyze the position of the Judiciary and the Prosecution in two cases, the legal basis of the right to abortion in cases of statutory rape, the theoretical framework of the principle of the best interests of the child, and medical aspects such as the (non-)existence of a time frame for abortion in legally admissible cases and the (im)possibility of the exercise of conscientious objection by physicians in this context. Methods: this paper makes use of the sociological of law and the legal-propositional research directions and follows an inductive thinking approach. Documentary and bibliographic analysis is conducted through a qualitative bibliographical review. This paper starts from the theoretical framework of the principle of the best interests of the child provided by Law No. 8.069/1990 to test the hypothesis that legal abortion is prima facie the procedure that best complies with the principle of the best interests of the child. Results: the pregnancy of a child is in itself a violation of a fundamental right. Abortion in the case of rape of a vulnerable person is a fundamental right explicitly guaranteed by law, without temporal or qualitative constraint.Conclusion: the hypothesis was confirmed, so that legal abortion should be understoodprima facieas the course of action that best corresponds to the principle of the best interests of the child.

Hysteroscopy as a standard procedure for assessing endometrial lesions among postmenopausal women.

CONTEXT AND OBJECTIVES: Endometrial cancer is the most prevalent type of malignant neoplasia of the genital tract. The objective of this study was to calculate the sensitivity, specificity, accuracy and positive and negative predictive values for diagnostic hysteroscopy, in comparison with histopathological tests, for all lesions of the endometrial cavity. DESIGN AND SETTING: Retrospective descriptive study at the public tertiary-level university hospital of Faculdade de Medicina de Ribeirão Preto, Universidade de São Paulo. METHODS: Diagnostic hysteroscopy was indicated in the following instances: endometrial thickness > 4 mm in asymptomatic patients; postmenopausal bleeding; and irregular endometrium or endometrium difficult to assess from ultrasound, with or without vaginal bleeding. Ultrasound evaluations were carried out no more than three months prior to hysteroscopy. RESULTS: There were 510 patients, with a mean age of 61.1+/-2.0 years and mean time elapsed since the menopause of 12.7+/-2.5 years. Endometrial biopsies were performed on 293 patients (57.5%). Histopathological analysis showed that 18 patients presented endometrial carcinoma or typical or atypical hyperplasia, and none of them presented endometrial thickness of less than 8 mm. No significant differences were found between the median thicknesses of the various benign lesions (p > 0.05). In our data, the sensitivity, specificity, accuracy and positive and negative predictive values for cancer or hyperplasia were 94.4%, 97.0%, 96.8%, 68% and 99.6%, respectively. CONCLUSIONS: Our results suggest that hysteroscopy is valuable as a diagnostic tool for malignant/hyperplastic and benign lesions, except for submucous myomas, for which the sensitivity was only 52.6%.

Effect of soybean phosphatidylcholine on lipid profile of bovine oocytes matured in vitro.

The phospholipid (PL) composition of embryo and oocyte membranes affects thermal phase behavior and several physicochemical properties such as fluidity and permeability. The characterization of PL profiles and the development of suitable in vitro maturation (IVM) protocols, that are able to modify membrane's composition, may result in significant improvements in oocyte developmental potential and cryotolerance. Using soybean phosphatidylcholine (PC) as a model supplement, we evaluated the effect of PL supplementation during IVM on bovine cumulus-oocyte-complex (COC). Substantial changes in the lipid profiles of oocyte membrane were observed and associated with pre-implantation data. The propensity of the PC supplement to become soluble in the maturation medium and/or diffuse into mineral oil was also assessed. Oocytes were matured in TCM without supplementation, i.e. control, (n=922) or supplemented with 50 or 100µM PC (n=994). The maturation media and mineral oil pre- and post- IVM, along with control and PC-treated oocytes were then analyzed using matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS), and the lipid profiles were compared via principal component analysis (PCA). Soybean PCs are bioavailable and stable in IVM medium; further, PCs did not diffuse to the mineral oil, which also remained unaltered by the metabolism of treated oocytes. PC supplementation at 100µM resulted in substantially greater relative abundances of polyunsatured PL, namely PC (32:1), PC (34:2), PC (36:6), PC (36:4), and PC (38:6), in oocyte membrane. These differences indicated that short-term exposure to the PC supplement could indeed modify the lipid composition of IVM-oocytes in a dose-dependent manner. Membrane incorporation of polyunsaturated molecular species of PC was favored, and does so without compromising the viability of the subsequent embryo in regards to cleavage, blastocyst development and hatching rate. The reported approach will allow for the development of novel strategies to modulate oocyte membrane dynamics and structure.

MALDI mass spectrometry reveals that cumulus cells modulate the lipid profile of in vitro-matured bovine oocytes.

The influence of cumulus cells (CC) on the lipid profile of bovine oocytes matured in two different lipid sources was investigated. Cumulus-oocyte complexes (COC) or denuded oocytes (DO) were matured in tissue culture medium (TCM) supplemented with fetal bovine serum (FBS) or serum substitute supplement (SSS). Lipid profiles of TCM, serum supplements, immature CC and oocyte (IO), and in vitro-matured oocytes from COC and DO were then analyzed by matrix assisted laser desorption ionization mass spectrometry (MALDI-MS) and submitted to partial least squares-discriminant analysis (PLS-DA). The developmental competence of such oocytes was also assessed. Differences in lipid composition were observed between two types of sera and distinctly influenced the lipid profile of CC. As revealed by PLS-DA, the abundance of specific ions corresponding to triacylglycerols (TAG) or phospholipids (PL) were higher in COC compared to DO both supplemented with FBS or SSS and to some extent affected the subsequent DO in vitro embryo development. DO exposed to SSS had however a marked diminished ability to develop to the blastocyst stage. These results indicate a modulation by CC of the oocyte TAG and PL profiles associated with a specific cell response to the serum supplement used for in vitro maturation.

Does the Access to Sun Exposure Ensure Adequate Levels of 25-Hydroxyvitamin D?

Objectives To assess the prevalence of hypovitaminosis D, altered arterial blood pressure, and serum levels of glucose and lipids in community-dwelling women in the city of Ribeirão Preto, in the southeast of Brazil. Methods This was a cross-sectional study of women aged 40-70 years old. Calcium intake and level of sun exposure were assessed by means of a questionnaire. A blood sample was used to determine glucose, lipid profile and 25-hydroxyvitamin D (25[OH]D) concentration. Results Ninety-one women were enrolled (age = 54.2 ± 7.1 years). The mean serum 25(OH)D concentration was 25.7 ± 8.9 ng/mL. A total of 24 (26.4%) women had 25(OH)D levels < 20 ng/mL. Seventy women (76.9%) had 25(OH)D levels < 30 ng/mL. Seventy-five women (90.4%) had inadequate calcium intake, and 61 women (67%) had appropriate sun exposure, 49 of whom (80.3%) had serum 25(OH)D levels < 30 ng/mL. Conclusion This study indicates that even in community-dwelling women, living in a city with high sun exposure, serum levels of 25(OH)D > 30 ng/ml are hardly reached. Thus, it is probable that other intrinsic factors besides sun exposure may regulate the levels of vitamin D.

Nutritional Counseling Promotes Changes in the Dietary Habits of Overweight and Obese Adolescents with Polycystic Ovary Syndrome.

Objective To evaluate the effects of nutritional counseling on the dietary habits and anthropometric parameters of overweight and obese adolescents with polycystic ovary syndrome (PCOS). Methods This was a prospective, longitudinal and auto-controlled study. Thirty adolescents aged 13-19 years-old, diagnosed with PCOS received nutritional counseling and were followed-up for 6 months. After the follow-up period, the results were evaluated through body weight, body mass index (BMI) and waist circumference (WC). Results Sixty-percent of the adolescents adhered to the nutritional counseling and, of these, 50% lost weight. Adolescents who lost weight changed their dietary habits by adopting hypocaloric diets and eating more meals per day, as per nutritional counseling. The waist circumference (WC) decreased significantly, although the body weight decreased non-significantly after adoption of a hypocaloric diet. Conclusion Although there was no significant weight loss, there was a considerable reduction in the WC associated with hypocaloric diets and with eating a greater number of meals per day.

Objetivo Avaliar os efeitos do aconselhamento nutricional sobre os hábitos alimentares e os parâmetros antropométricos de adolescentes com sobrepeso e obesidade e com síndrome do ovário policístico (SOP). Métodos Este foi um estudo prospectivo, longitudinal e autocontrolado. Trinta adolescentes com idades entre 13 e 19 anos e diagnosticadas com SOP receberam aconselhamento nutricional. Após 6 meses de acompanhamento, os resultados foram avaliados através do peso corporal, índice de massa corporal (IMC) e a circunferência da cintura (CC). Resultados Sessenta por cento das adolescentes aderiram ao aconselhamento nutricional e, destas, 50% perderam peso. Adolescentes que perderam peso mudaram seus hábitos alimentares adotando dietas hipocalóricas e comendo mais refeições por dia, seguindo orientação nutricional. A circunferência da cintura (CC) diminuiu significativamente, embora o peso corporal tenha diminuído de forma não significativa após a adoção de uma dieta hipocalórica. Conclusão Embora a perda de peso não tenha sido significativa, houve redução considerável da CC associada a dietas hipocalóricas e à ingestão de um maior número de refeições por dia.

Dataset on lipid profile of bovine oocytes exposed to Lα-phosphatidylcholine during in vitro maturation investigated by MALDI mass spectrometry and gas chromatography-flame ionization detection.

Data presented in this article are related with the research article entitled "Effect of soybean phosphatidylcholine on lipid profile of bovine oocytes matured in vitro" [1]. This article describes the differences in the relative abundance of the lipid ions detected by matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) in control and Lα-phosphatidylcholine-treated oocytes. In addition, the fatty acids (FA) content in pure Lα-phosphatidylcholine supplement and oocytes was analyzed by gas chromatography-flame ionization detection (GC-FID). The dataset provides information and inputs for further studies aiming to optimize in vitro maturation conditions and cryotolerance of mammalian oocytes.

Zika Virus Infection in Pregnant Women and Microcephaly.

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. The most frequent clinical variables are rash, febrile state, non-purulent 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.

Desde a descoberta do vírus Zika (VZIK) em 1947 em Uganda, na África, até sua chegada na América do Sul, não se tinha notícia de que ele seria capaz de comprometer a vida reprodutiva em humanos de forma tão severa. Hoje, sabe-se que os danos sobre o sistema nervoso central são múltiplos, e a microcefalia é considerada a ponta do iceberg, visto que na realidade ela representa o epílogo de um processo devastador desta infecção sobre o sistema nervoso central do embrião e do feto. Em decorrência da agressão do sistema nervoso central pelo VZIK, esta infecção pode provocar artrogripose, disfagia, surdez e comprometimento visual. Todas estas alterações, de gravidade variável, direta ou indiretamente comprometem a vida futura dessas crianças, já sendo considerada uma síndrome congênita ligada ao VZIK. Uma das principais dificuldades na abordagem dessa infecção é relativa ao diagnóstico. Considerando a parte clínica, observa-se que ela apresenta manifestações comuns às infecções pelos vírus da dengue e da febre chikungunya, variando apenas em suas intensidades subjetivas. As variáveis clínicas mais frequentes são o exantema, febrícula, conjuntivite não purulenta e artralgia. No tocante aos recursos laboratoriais, também existem limitações ao diagnóstico subsidiário. As provas de biologia molecular se fundamentam na reação em cadeia da polimerase (RCP) com ação da transcriptase reversa (TT), visto que o VZIK é um vírus ácido ribonucleico (ARN). A TR-RCP apresenta positividade sérica ou plasmática por um período curto de tempo, não ultrapassando cinco dias após início dos sinais e sintomas. Esta pesquisa do VZIK na urina fica positiva por período mais prolongado, chegando a 14 dias. Ainda não existem técnicas seguras para diagnóstico sorológico dessa infecção. Não havendo complicações (meningoencefalite ou síndrome de Guillain-Barré), dificilmente são necessários mais exames complementares para avaliar o comprometimento sistêmico. No entanto, são necessárias provas para descartar as outras infecções que causam exantema, como dengue, chikungunya, sífilis, toxoplasmose, citomegalovírus, rubéola e herpes. Sabe-se que não existe terapia antiviral específica contra o VZIK, e a abordagem terapêutica de gestantes portadoras da infecção limita-se ao uso de antitérmicos e analgésicos. Orienta-se evitar anti-inflamatórios até que o diagnóstico de dengue seja descartado. Sobre a condução do pré-natal, não há necessidade de modificar o cronograma de consultas pré-natais para gestantes que foram infectadas pelo VZIK, mas é necessária a garantia de três exames ecográficos durante a gravidez para gestantes de baixo risco, e mensais para a gestante com infecção confirmada pelo VZIK. A via de parto é vaginal, e está liberado o aleitamento natural.

Quality of Life in Women with Polycystic Ovary Syndrome after a Program of Resistance Exercise Training.

Purpose Aerobic exercises may improve quality of life (QoL) in women with polycystic ovary syndrome (PCOS). However, there is no data on the effect of resistance exercise training (RET) programs on the QoL of women with PCOS. Thus, this study aimed to assess the effect of a 16-week RET program on QoL in PCOS women. Methods This 16-week case-control study enrolled 43 women with PCOS (PCOS group, PCOSG) and 51 healthy pre-menopausal controls aged 18 to 37 years (control group, CG). All women underwent a supervised RET program for 16 weeks, and were evaluated in two different occasions: week-0 (baseline), and week-16 (after RET). Quality of life was assessed using the 36-Item Short Form Health Survey (SF-36). Results Testosterone reduced significantly in both groups after RET (p < 0.01). The PCOSG had improvements in functional capacity at week-16 relative to week-0 (p = 0.02). The CG had significant improvements in vitality, social aspects, and mental health at week-16 relative to week-0 (p ≤ 0.01). There was a weak correlation between social aspects of the SF-36 domain and testosterone levels in PCOS women. Conclusion A 16-week RET program modestly improved QoL in women with PCOS.

Driving Human Granulosa-Luteal Cells Recovered From In Vitro Fertilization Cycles Toward the Follicular Phase Phenotype.

Culture systems are available for human granulosa cells (GCs) that perpetuate luteinization. The present study examines the plating density effects and long-term serum-free culture on the in vitro dynamics differentiation of luteinizing human GCs. Cells were cultured in serum-free α-minimum essential medium (α-MEM) or serum-based tissue culture medium (TCM). The time course of GCs morphology and secretion of estradiol (E2), progesterone (P4), and relaxin were analyzed after 48, 96, and 144 hours of culture. Other functional markers as follicle-stimulating hormone/luteinizing hormone receptors and steroidogenic enzymes were investigated at the end of culture. The morphology of an α-MEM cell rather than a TCM cell resembles more closely that seen in vivo. Compared to TCM cultures, α-MEM cells secreted 93.7% and 87.2% more E2 and approximately 7% and 17% of the amount of P4 when cultured at densities of 2 × 10(4) or 4 × 10(4) cells/well, respectively. Relaxin secretion was significantly reduced in α-MEM cultures. α-MEM cells were estrogenic and expressed the CYP19 gene. Levels of CYP17 increased about 8-fold in α-MEM cells above the levels found in TCM cells. Our results reveal new insights into human GCs differentiation in vitro and demonstrate the critical importance of the culture system and cell-plating density on the establishment of estrogenic or progestogenic GC phenotypes.

Vaginal administration of allopregnanolone to postmenopausal women undergoing estrogen replacement therapy: preliminary results.

OBJECTIVE: To assess the tolerability and endometrial effects of vaginal administration of an allopregnanolone gel to postmenopausal women undergoing estrogen therapy. METHODS: Thirteen postmenopausal women included in the study were divided into two groups and submitted to two consecutive cycles of 28 days during which they received 2 mg oral estradiol valerate daily and vaginally administered allopregnanolone gel during the last 10 days of the second cycle (group 1) or during the last 10 days of each cycle (group 2). Systemic adverse effects, vaginal bleeding and endometrial histology were characterized, with group 1 patients being submitted to two endometrial biopsies (days 28 and 56) and group 2 patients to one biopsy (day 56). RESULTS: Five patients did not show any adverse effect. Mastalgia was the most frequently reported adverse effect (four cases), followed by headache and abdominal pain (two cases each). The adverse effects were mild and did not interfere with the adequate use of the medication prescribed. Vaginal bleeding due to deprivation was observed in three of the seven patients submitted to one treatment cycle with allopregnanolone (group 1) and in two of six patients submitted to two treatment cycles (group 2). Endometrial biopsy findings did not suggest any secretory action after exposure to allopregnanolone. CONCLUSIONS: Tolerability of vaginal administration of allopregnanolone gel was good. Studies employing a larger series and longer time of follow-up are necessary to determine the endometrial effects of this drug.
