Sexual function of transgender women after gender affirming surgery: A mini review.

A transgender person has a gender identity opposite to the sex assigned at birth. Transgender individuals may have altered sexual function (SF) due to psychosocial factors related to body image distortion, shame, and dissatisfaction with genital appearance, and these conditions can increase the risk of sexual dysfunction. This study aimed to characterize the SF of trans-women after gender affirming surgery (GAS). We reviewed the Pubmed database for studies published between January 2008 and December 2021. 17 studies were included, four were cross-sectional studies, one prospective study, four prospective cohort studies, five retrospective studies. The instruments used to evaluate the SF were female sexual function index, semistructured questionnaires, patients' opinion, Sexual Desire Inventory, Maudsley Marital Questionnaire-S, WHOQOL-100. The results of our review indicate there is weak evidence that GAS improves the SF of trans-women. We thus recommend that future studies use questionnaires that are validated for the assessment of the SF of trans-women to better determine the impact of genital surgery in this population.

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.

Pelvic floor muscle strength and urinary incontinence in hyperandrogenic women with polycystic ovary syndrome.

INTRODUCTION AND HYPOTHESIS: Hyperandrogenism in women with polycystic ovary syndrome (PCOS) could increase muscle mass and thereby pelvic floor muscle (PFM) strength, reducing the risk of urinary incontinence (UI). The aim of the present study was to assess PFM strength and UI among hyperandrogenic women with PCOS and a control group for comparison. METHODS: This is an observational, cross-sectional, case-control study. Seventy-nine women, aged 18 to 40 years with a mean body mass index (BMI) of 23.4 kg/cm(2) were recruited at the University Hospital: PCOS (n = 36) and control group for comparison (n = 43). All PCOS women had clinical and/or laboratory hyperandrogenism (> 80 ng/dL) and control women had regular menstrual cycles. PFM strength was assessed by vaginal manometry. The International Consultation on Incontinence Questionnaire of Urinary Incontinence Short Form (ICIQ-UI SF) was used to assess UI. Descriptive analysis, analysis of variance (ANOVA) and Fisher's exact test were used for statistical analyses. RESULTS: There was no statistically significant difference in mean PFM strength between the PCOS and the control group: 2.7 cm H2O (95% CI -6.2-11.6) p = 0.55. The prevalence of UI was 18.6% in the control group compared with 0% in the PCOS group p < 0.01. CONCLUSIONS: Women with PCOS showed absence of UI, but PFM strength did not differ from the control group.

Breaking Bad News in Obstetrics and Gynecology: We Must Talk About It.

Breaking bad news is common in obstetrics and gynecology (ob-gyn). However, it is difficult, and few doctors receive training on how to deal with this situation. This narrative review aims to gather, analyze, and synthesize part of the knowledge on the area, focused on Ob-Gyn. Among the 16 selected articles, two are randomized controlled intervention studies, and most studies refer to obstetrics. The results found by us pointed out that simulation, feedback/debriefing, lectures, and protocols could improve doctors' performance in communicating bad news. For patients, the context and how the information is transmitted seem to impact more than the content of the news. Ob-Gyn doctors could benefit from specific protocols and education, given the specialty's particularities. There is a lack of evidence about the most effective way to conduct such training. Finding validated ways to quantify and classify studies' results in the area, which would allow for the objective analysis of outcomes, is one of the biggest challenges concerning this topic.

Dar más notícias é comum em obstetrícia e ginecologia. Porém, é difícil e poucos médicos recebem treinamento sobre como lidar com essa situação. Esta revisão narrativa tem como objetivo reunir, analisar e sintetizar parte do conhecimento sobre a área, com foco na obstetrícia. Dentre os 16 artigos selecionados, dois são estudos de intervenção randomizados e controlados, e a maioria dos estudos refere-se à obstetrícia. Os resultados encontrados ressaltaram que simulação, feedback/entrevistas, palestras e protocolos podem melhorar o desempenho dos médicos na comunicação de más notícias. Para os pacientes, o contexto e como as informações são transmitidas parecem ter maior impacto do que o conteúdo das notícias. Os obstetras e ginecologistas poderiam se beneficiar de cursos e protocolos específicos, dadas as particularidades da especialidade. Faltam evidências sobre a forma mais eficaz de realizar esse treinamento. Encontrar formas validadas de quantificar e classificar os resultados dos estudos na área, permitindo uma análise objetiva dos resultados, é um dos maiores desafios neste tema.

Influence of third-generation oral contraceptives on the complexity analysis and symbolic dynamics of heart rate variability.

OBJECTIVE: To evaluate the influence of oral contraceptives (OCs) containing 20 µg ethinylestradiol (EE) and 150 µg gestodene (GEST) on the autonomic modulation of heart rate (HR) in women. METHODS: One-hundred and fifty-five women aged 24 ± 2 years were divided into four groups according to their physical activity and the use or not of an OC: active-OC, active-non-OC (NOC), sedentary-OC, and sedentary-NOC. The heart rate was registered in real time based on the electrocardiogram signal for 15 minutes, in the supine-position. The heart rate variability (HRV) was analysed using Shannon's entropy (SE), conditional entropy (complexity index [CInd] and normalised CInd [NCI]), and symbolic analysis (0V%, 1V%, 2LV%, and 2ULV%). For statistical analysis the Kruskal-Wallis test with Dunn post hoc and the Wilcoxon test (p < 0.05 was considered significant) were applied. RESULTS: Treatment with this COC caused no significant changes in SE, CInd, NCI, or symbolic analysis in either active or sedentary groups. Active groups presented higher values for SE and 2ULV%, and lower values for 0V% when compared to sedentary groups (p < 0.05). CONCLUSION: HRV patterns differed depending on life style; the non-linear method applied was highly reliable for identifying these changes. The use of OCs containing 20 µg EE and 150 µg GEST does not influence HR autonomic modulation.

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.

The effects of hypoestrogenism on the vaginal wall: interference with the normal sexual response.

INTRODUCTION: The sexual response depends on the adequate function of all systems related to the genital and extra-genital organs. Physiological conditions such as menopause can interfere with sexual expression because of central and peripheral changes. Genital effects of estrogen include vaginal trophism, lubrication, and local pleasure sensation in the sexual arousal phase. Hypoestrogenism causes changes in the four layers of the vaginal wall that may result in dyspareunia and a loss in the quality of the genital arousal response. AIM: The purpose of this review is to highlight the changes in the vaginal wall caused by hypoestrogenism, its possible relationship with dyspareunia, and its repercussions for genital arousal. Treatments for hypoestrogenism are also discussed. METHODS: We evaluated the data available in PubMed (1982-2008) and surveyed the reference list for relevant studies. Two reviewers analyzed the data independently. A study was considered to be of high quality if it had all three of the following characteristics: (i) prospective design; (ii) valid data; and (iii) adequate sample size. Reviews and experimental animal studies were also considered. MAIN OUTCOME MEASURES: Normal genital morphology, hypoestrogenism and hormone replacement therapy were the focus of the studies reviewed in this paper. RESULTS: Atrophy of the vaginal wall may be associated with dyspareunia and genital sexual arousal disorder, but psychological and sociocultural aspects must also be considered. Regardless, however, local estrogen therapy is useful in improving vaginal wall trophism and, thus, in improving the sexual response. CONCLUSIONS: There are many possible alterations in the structure of the vaginal wall that are related to estrogen deficiency that may require medical intervention beyond the usual strategies used to attain adequate sexual function. Physicians should attempt to treat these alterations, and more research is needed to elucidate the physiopathology of dyspareunia and genital sexual arousal physiology.

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.

Sexuality during the climacteric period.

BACKGROUND: Cultural, social, physiological and psychological factors may alter the course of sexual function in climacteric women. OBJECTIVE: The objective of the present literature review is to survey the prevalence of sexual dysfunctions in the climacteric and to establish the association between the organic and psychic changes that occur during this phase and sexual dysfunction. We also discuss potential treatments. METHODS: We evaluated the data available in PubMed (1982-2008). For each original article, two reviewers analyzed the data independently and considered a study to be of high quality if it had all three of the following characteristics: prospective design, valid data and adequate sample size. Both reviewers extracted data from each of the 99 studies selected: 34 cross-sectional studies, 25 cohort studies, 9 trials, 31 reviews related to sexuality in pre- and post-menopausal women. RESULTS: Sexual dysfunction among climacteric women is widespread and is associated with bio-psychosocial factors. However, there is not enough evidence to correlate sexual dysfunction with a decrease in estrogen levels and biological aging. A strong association exists between climacteric genital symptoms and coital pain. There is, however, sufficient evidence demonstrating the benefits of local estrogen therapy for patients with genital symptoms. CONCLUSION: A significant decline in sexual function occurs in climacteric women, although it is still unclear whether this is associated with the known decrease in estrogen levels or with aging, or both. Relational factors may interfere with sexual function during this phase. The climacteric genital symptoms improve with estrogen replacement therapy, and positively influence sexual function. Further studies are needed to establish the actual impact of the decrease in estrogen levels and of aging on the sex life of climacteric women.

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.

Insulin, ghrelin and early return of hunger in women with obesity and polycystic ovary syndrome.

BACKGROUND & AIMS: Women with polycystic ovary syndrome (PCOS) have greater predisposition to obesity, but the mechanisms are still unknown. Hyperinsulinemia, insulin resistance and low levels of ghrelin are common in this group. For the purposes of the present study, it was assumed that such changes could have an influence on hunger. This study aimed to assess the hunger pattern before and after an ad libitum meal and the association between insulin and plasma ghrelin with hunger perception in women with obesity, with and without PCOS. METHOD: This cross-sectional study included 53 women with obesity, 30 with PCOS, and 23 controls (with obesity but without PCOS). Insulin, ghrelin, glucose and subjective ratings of hunger (by 100 mm visual analogue scales) were analyzed in a fasting state, preprandially at 12:00 before the ad libitum meal, and postprandially 15, 45, 75 and 135 min after the beginning of the ad libitum meal. RESULTS: There was a significant increase in hunger one hour after the beginning of the ad libitum meal (75 min) in the PCOS group (p = .01) compared to 15 min, whereas this only occurred after 135 min in the control group (2 h later). The usual energy intake adjusted by the intra-individual variability was higher in the PCOS group than in the control group (2309 ±â€¯461 kcal·d-1 × 2124 ±â€¯480 kcal·d-1; p = .04). The concentrations of insulin and ghrelin, in both preprandial and postprandial periods, were not associated with the perception of hunger. CONCLUSIONS: Women with obesity and PCOS had an earlier return of hunger in the postprandial period after an ad libitum meal, but there was not associated with postprandial ghrelin and insulin levels.

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.

Se utiliza el análisis documental y bibliográfico, a través de una revisión bibliográfica cualitativa. Parte del marco teórico del principio del interés superior del niño y del adolescente, previsto en la Ley n. 8.069/1990, para contrastar la hipótesis de que la interrupción legal del embarazo debe entenderse prima facie como el curso de acción que mejor se adapta al principio del interés superior del niño. Resultados: el embarazo infantil, por sí solo, ya es una vulneraciónde un derecho fundamental. La interrupción del embarazo en casos de violación de una persona vulnerable es un derecho fundamental, expresamente garantizado por la ley, sin ninguna condición temporal o cualitativa. Conclusión: a partir de los casos presentados, siguiendo la metodología señalada anteriormente, se confirmó la hipótesis de que la interrupción legal del embarazo debe entenderse prima facie como el curso de acción que mejor se ajusta al principio del interés superior del niño.

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%.

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.

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.
