Maternal childhood maltreatment: associations to offspring brain volume and white matter connectivity.

The deleterious effects of adversity are likely intergenerational, such that one generation's adverse experiences can affect the next. Epidemiological studies link maternal adversity to offspring depression and anxiety, possibly via transmission mechanisms that influence offspring fronto-limbic connectivity. However, studies have not thoroughly disassociated postnatal exposure effects nor considered the role of offspring sex. We utilized infant neuroimaging to test the hypothesis that maternal childhood maltreatment (CM) would be associated with increased fronto-limbic connectivity in infancy and tested brain-behavior associations in childhood. Ninety-two dyads participated (32 mothers with CM, 60 without; 52 infant females, 40 infant males). Women reported on their experiences of CM and non-sedated sleeping infants underwent MRIs at 2.44 ± 2.74 weeks. Brain volumes were estimated via structural MRI and white matter structural connectivity (fiber counts) via diffusion MRI with probabilistic tractography. A subset of parents (n = 36) reported on children's behaviors at age 5.17 ± 1.73 years. Males in the maltreatment group demonstrated greater intra-hemispheric fronto-limbic connectivity (b = 0.96, p= 0.008, [95%CI 0.25, 1.66]), no differences emerged for females. Fronto-limbic connectivity was related to somatic complaints in childhood only for males (r = 0.673, p = 0.006). Our findings suggest that CM could have intergenerational associations to offspring brain development, yet mechanistic studies are needed.

Efficacy of Fractional Laser on Steroid Receptors in GSM Patients.

BACKGROUND: To compare the efficacy of CO2 fractional laser with that of topical estriol for treating genitourinary syndrome of menopause and to investigate the relationship between epithelial thickness and vaginal atrophy. METHODS: Twenty-five menopausal women were randomized to receive either laser or estrogen treatment. Vaginal biopsies before and after treatment were compared to assess the amount and distribution of estrogen and progesterone receptors. RESULTS: Estrogen receptor levels were statistically similar between groups before and after treatment. Although there was no change over time in the estrogen group, an increase in receptor levels was confirmed in the laser group. Changes in estrogen receptor levels showed no association with treatment. Progesterone receptor levels were statistically similar between groups throughout treatment. There was no change over time in both groups. These changes displayed no association with the type of treatment. There was no significant correlation between epithelium thickness and estrogen or progesterone receptor levels. CONCLUSIONS: Estrogen and progesterone receptor levels increased and were maintained, respectively, in the vaginal epithelium in both groups. There was no significant relationship between epithelium thickness and receptor density. Laser therapy had similar outcomes to the gold standard without involving the disadvantages of hormone therapy.

ABSTRACT Purpose To compare the central auditory abilities of climacteric women, with and without hormone replacement therapy. Methods Observational study, performed with climacteric women with and without hormone replacement therapy. Sound localization tests were performed in five directions; Sequential Verbal Memory Test; Sequential Memory Test for Nonverbal Sounds; Duration Pattern Test; Random Gap Detection Test); Masking Level Difference; Dichotic Digit Test and Speech With White Noise Test and the questionnaire "Informal Fatigue Assessment" was applied. Results The differences pointed out revealed the biased difference that occurs due to higher average performance in the group with TH compared to the group without TH for TMSnV. In the TLS, TMSN, RGDT and MLD tests, the group with HT presented quantitatively better results. Conclusion Climacteric women, with and without hormone therapy, have central auditory processing disorder involving the auditory skills of sound localization, simple and complex temporal ordering, background figure, temporal resolution and binaural interaction. However, women in the hormone therapy group performed better in simple temporal ordering.

End-of-life use of antibiotics: a survey on how doctors decide.

OBJECTIVES: Infections are the main complications in terminal diseases. Many patients die using antibiotics, which raises questions about their real usefulness and role in unnecessary prolongation of suffering. This survey evaluated how doctors use antibiotics in palliative care. METHODS: From June to August of 2016, an online survey was conducted with 224 doctors who provide palliative care. They had to decide whether to initiate antibiotics in fictitious scenarios involving patients with suspected infections (urinary tract infection, pneumonia, sepsis) in end-of-life (from cancer, dementia, malignant stroke with sequelae, advanced COPD, multiple organ failure). Then, they had to decide whether to stop, maintain, or extend antibiotics after non-response in 72 hours. RESULTS: 88-100% of doctors decided to initiate antibiotics in all situations, except in advanced dementia (45%), and most of them decided to maintain/extend antibiotics inadequately. Factors associated with maintaining/extending antibiotics inadequately were: longer time since graduation (over 13 years; significant in all 7 clinical situations; OR range: 2.45-10.11), and not having formal specialization in palliative care (statistically significant in 3 of 7 situations). CONCLUSIONS: Most palliative care physicians in this study decided to initiate and maintain/extend antibiotics at the end-of-life.

Validade do questionário internacional de atividade física (IPAQ) em idosos: uma revisão integrativa da literatura

Introdução: O questionário Internacional de Atividade Física (IPAQ) tem sido amplamente utilizado nas pesquisas. É considerado uma boa ferramenta de medição de Atividade Física (AF), no entanto, este questionário não é específico para idosos, geralmente, é aplicado à população em geral. Objetivo: Realizar uma Revisão Integrativa da Literatura apresentando os estudos que investigaram a validade do IPAQ na avaliação de AF em idosos nos últimos seis anos. Métodos: Foi realizada uma Revisão Integrativa da Literatura nas bases de dados PUBMED, BVS e SCOPUS, relativa aos anos de 2014 a 2020, utilizando-se os descritores: Elderly, Aged, IPAQ questionnaire validity, Physical Activity e Exercise. Resultados: Foram selecionados oito artigos cuja metodologia apresenta a validade do IPAQ, na avaliação em idosos com idade ≥65 anos. Seis dos artigos selecionados apresentaram em suas metodologias a avaliação realizada pelo IPAQ-L (versão longa), e apenas dois artigos apresentaram IPAQ-S (versão curta). Conclusão: O IPAQ- L tem sido amplamente utilizado para avaliar os níveis de AF e comportamento sedentário (CS) em idosos. As evidências demonstram que a aplicação do questionário combinado com os dados do acelerômetro, tem mostrado medições satisfatórias, no entanto, futuras versões devem ser estruturadas para atender a este público específico.

Intra-session test-retest reliability of functional connectivity in infants.

Resting functional MRI studies of the infant brain are increasingly becoming an important tool in developmental neuroscience. Whereas the test-retest reliability of functional connectivity (FC) measures derived from resting fMRI data have been characterized in the adult and child brain, similar assessments have not been conducted in infants. In this study, we examined the intra-session test-retest reliability of FC measures from 119 infant brain MRI scans from four neurodevelopmental studies. We investigated edge-level and subject-level reliability within one MRI session (between and within runs) measured by the Intraclass correlation coefficient (ICC). First, using an atlas-based approach, we examined whole-brain connectivity as well as connectivity within two common resting fMRI networks - the default mode network (DMN) and the sensorimotor network (SMN). Second, we examined the influence of run duration, study site, and scanning manufacturer (e.g., Philips and General Electric) on ICCs. Lastly, we tested spatial similarity using the Jaccard Index from networks derived from independent component analysis (ICA). Consistent with resting fMRI studies from adults, our findings indicated poor edge-level reliability (ICC = 0.14-0.18), but moderate-to-good subject-level intra-session reliability for whole-brain, DMN, and SMN connectivity (ICC = 0.40-0.78). We also found significant effects of run duration, site, and scanning manufacturer on reliability estimates. Some ICA-derived networks showed strong spatial reproducibility (e.g., DMN, SMN, and Visual Network), and were labelled based on their spatial similarity to analogous networks measured in adults. These networks were reproducibly found across different study sites. However, other ICA-networks (e.g. Executive Control Network) did not show strong spatial reproducibility, suggesting that the reliability and/or maturational course of functional connectivity may vary by network. In sum, our findings suggest that developmental scientists may be on safe ground examining the functional organization of some major neural networks (e.g. DMN and SMN), but judicious interpretation of functional connectivity is essential to its ongoing success.

Comparison of topical fractional CO2 laser and vaginal estrogen for the treatment of genitourinary syndrome in postmenopausal women: a randomized controlled trial.

OBJECTIVE: To compare the efficacy of fractional CO2 laser therapy with topical estrogen therapy for the treatment of postmenopausal genitourinary syndrome of menopause. METHODS: We conducted a randomized controlled clinical trial involving 25 postmenopausal women. Participants were aged between 50 and 65 years with at least 1 year of amenorrhea and follicle-stimulating hormone levels of >40 IU/L. The women were randomized into two groups: the laser therapy group (n = 13) and the vaginal topical estrogen therapy group (n = 12). Changes in the vaginal epithelium thickness, Frost index, and cell maturation were analyzed in both the groups. The female sexual quotient of each woman was also evaluated. Subjective evaluation was performed through a physical examination. RESULTS: Histological analysis showed a significant increase in the vaginal epithelium thickness at the end of treatment in females in both the laser therapy (P < 0.001) and topical estrogen therapy (P = 0.001) groups. The topical estrogen therapy group tended to present a higher maturation index at the end of treatment when compared with that of the other group. Sexual function increased significantly over time in both the topical estrogen therapy (P < 0.001) and laser therapy (P < 0.001) groups. Subjective evaluation through physical examination showed a significant improvement in atrophy in both the groups. CONCLUSION: Despite the nonequivalence with topical estrogen therapy, our data suggest that laser therapy is an effective method for the treatment of vulvovaginal atrophy.

Effects of gradual weight loss on strength levels and body composition in wrestlers athletes.

BACKGROUND: Few investigations have evaluated isokinetic torque after a period of weight loss in wrestlers. Thus, the current study sought to investigate the effects of gradual weight loss in the precompetitive period on isokinetic peak torque in the upper and lower limbs and body composition in wrestling athletes. METHODS: Eight elite athletes participated in the study (mean age 20.8±3.1 years). The athletes visited the laboratory on 2 occasions: during the period of weight maintenance (baseline) and during weight loss, in the precompetitive period (post). The variables analyzed were body composition through air displacement plethysmography (BOD POD) and peak torque (PT) of knee flexion and extension movements, and internal and external shoulder rotation in concentric action, at speeds of 60°/s and 180°/s, determined using an isokinetic dynamometer (Biodex Medical Systems; Shirley, NY, USA). RESULTS: A significant decrease was observed in body composition values, except lean mass. No significant differences were observed in the PT of the movements analyzed: Shoulder internal rotation (60°/s P=0.825; 180°/s P=0.245) and external rotation (60°/s P=0.149; 180°/s P=0.163) and knee extension (60°/s P=0.086; 180°/s P=0.630) and flexion (60°/s P=0.310; 180°/s P=0.239). CONCLUSIONS: Gradual weight loss did not affect the production of torque in the wrestlers before a competition. In addition, gradual weight loss contributed to a reduction in body fat, associated with an increase in percentage lean body mass.

Reduction of prefrontal thickness in military police officers with post-traumatic stress disorder

Abstract Background Brain-imaging studies in post-traumatic stress disorder (PTSD) have consistently revealed alterations in brain structure and function and this is correlated to symptomatology. However, few studies have investigated the role of biomarkers in PTSD some specific groups, as police officers. Objective To evaluate prefrontal and limbic volumes, and cortical thickness of police officers exposed to trauma during work who developed post-traumatic stress disorder, resilient matched controls (without PTSD), and compared to healthy civilians. Methods Prefrontal and limbic volumes, and cortical thickness of 12 police officers with PTSD, 12 resilient police officers, and 12 healthy civilians who underwent brain MRI were analyzed. Results Differences in limbic structures volume were not significative after Bonferroni correction. A significant reduction in cortical thickness on right rostral cingulate, right and left middle frontal gyrus, left superior frontal, left lingual, calcarine and cuneus were observed in PTSD group in comparison to controls was observed. Discussion Although preliminary, our results suggested not only the association between cortical thickness and PTSD, but also indicated that patients and controls have anatomical differences.

Experience of an online course on sexuality during pregnancy for residents.

OBJECTIVE: Many obstetrics and gynecology (Ob/Gyn) residents report insufficient knowledge about female sexuality and this has a negative impact on their capacity to manage their patients. The aim of this study was to describe an online course about sexuality during pregnancy for Brazilian Ob/Gyn residents and evaluate their knowledge acquisition. METHODS: This longitudinal educational intervention study involved 219 Brazilian Ob/Gyn residents. The online course lasted 24h (10 video lectures and discussion chats). Upon enrollment, the participants answered a questionnaire in regard to their training, attitudes and practices about sexuality during pregnancy. Participants' knowledge acquisition was assessed using a pre- and post-course test about sexuality during pregnancy. At the end of the course, participants were asked to evaluate their educational experience. Student's t and chi-square tests were used to analyze the pre- and post-course test scores. P values<0.05 were considered statistically significant. RESULTS: A total of 143 Ob/Gyns (65.3% of those enrolled) completed the course. At baseline, most participants reported that they did not have any sexology classes as undergraduates (62.5%) or in their residency (52.1%), and that they lacked specific knowledge in this area to manage their patients. Mean test scores increased significantly at the end of the course: 4.4 (±1.6) versus 6.0 (±1.3) (out of a maximum score of 10), before and after the course, respectively (p<0.0001). Most of the residents rated the overall quality of the course as "higher than expected". CONCLUSION: An online course for Ob/Gyn residents was associated with a significant increase in knowledge about sexuality during pregnancy.

Association between asthma and female sex hormones.

CONTEXT AND OBJECTIVE:: The relationship between sex hormones and asthma has been evaluated in several studies. The aim of this review article was to investigate the association between asthma and female sex hormones, under different conditions (premenstrual asthma, use of oral contraceptives, menopause, hormone replacement therapy and pregnancy). DESIGN AND SETTING:: Narrative review of the medical literature, Universidade Federal do Tocantins (UFT) and Universidade Federal de São Paulo (Unifesp). METHODS:: We searched the CAPES journal portal, a Brazilian platform that provides access to articles in the MEDLINE, PubMed, SciELO, and LILACS databases. The following keywords were used based on Medical Subject Headings: asthma, sex hormones, women and use of oral contraceptives. RESULTS:: The associations between sex hormones and asthma remain obscure. In adults, asthma is more common in women than in men. In addition, mortality due to asthma is significantly higher among females. The immune system is influenced by sex hormones: either because progesterone stimulates progesterone-induced blocking factor and Th2 cytokines or because contraceptives derived from progesterone and estrogen stimulate the transcription factor GATA-3. CONCLUSIONS:: The associations between asthma and female sex hormones remain obscure. We speculate that estrogen fluctuations are responsible for asthma exacerbations that occur in women. Because of the anti-inflammatory action of estrogen, it decreases TNF-α production, interferon-γ expression and NK cell activity. We suggest that further studies that highlight the underlying physiopathological mechanisms contributing towards these interactions should be conducted.

RESUMO CONTEXTO E OBJETIVO: A relação entre os hormônios sexuais e a asma tem sido investigada em diversos estudos. Esta revisão tem como objetivo descrever a relação entre hormônios sexuais (endógenos e exógenos) e a inflamação nas vias aéreas, especialmente na asma, em eventos diferentes (na asma pré-menstrual, durante o uso de anticoncepcionais, na menopausa, no uso de terapia hormonal e na gestação). TIPO DE ESTUDO E LOCAL: Revisão narrativa da literatura médica, Universidade Federal do Tocantins (UFT) e Universidade Federal de São Paulo (Unifesp). MÉTODO: Pesquisamos o Portal de Periódicos Capes, uma plataforma brasileira que fornece acesso a artigos nas bases de dados MEDLINE, PubMed, SciELO e LILACS. Os descritores utilizados foram asma, hormônios sexuais, mulheres e uso de anticoncepcionais, com base no "Medical Subject Headings". RESULTADOS: As associações entre hormônios sexuais e asma ainda permanecem obscuras. Em adultos, a asma é mais frequente em mulheres do que em homens. Além disso, a mortalidade por asma é significativamente maior no sexo feminino, destacando-se que o sistema imunológico sofre influência de hormônios sexuais, seja porque a progesterona estimula o fator bloqueador induzido pela progesterona e citocinas Th2 ou porque contraceptivos derivados de progesterona e estrógeno estimulam o fator de transcrição GATA-3. CONCLUSÕES: A associação entre asma e hormônios sexuais femininos permanece obscura. Nós especulamos que as flutuações do estrogênio são responsáveis pelas exacerbações da asma que ocorrem nas mulheres. Devido à ação anti-inflamatória do estrogênio há redução da produção de TNF-α, da expressão do interferon-γ e da atividade das células NK. Sugerimos que sejam realizados novos estudos para esclarecer os mecanismos fisiopatológicos dessas interações.

IGF-1R and Leptin Expression Profile and the Effects of Metformin Treatment on Metabolic and Endocrine Parameters in PCOS Mice.

We aim to assess the effects of metformin treatment on metabolic and endocrine parameters and genes expression related to the insulin-responsive pathway in polycystic ovary syndrome (PCOS). This study comprises twenty-eight obese mice divided into three metformin-treated groups for seven and twenty days and eight nonobese and nontreated ones. We found a significant decrease in glycemia after metformin treatment at days seven and twenty. However, we did not observe differences in body weight measurement. Histologically, after twenty days we observed follicular development with regression of androgenic effects. Levels of IGF-1R protein expression were low after twenty days of treatment, but LEP proteins showed an overexpression in the ovarian stroma. We assessed the IGF-1R and LEP mRNAs levels; data showed a significant overexpression of LEP after seven days of treatment, while the IGF-1R was downregulated. Metformin therapy seems to exert a beneficial effect on histological and anovulatory features, reducing follicular number and pyknosis formation, possibly involved in the reversion of androgenic stimulus. Expression of IGF-1 and LEPR indicates a relevant role in androgenic features reversion present in PCOS, hormonal equilibrium, body weight regulation, and glucose metabolism, therefore, under phenotype obesity and infertility regulation in this model.

Nanotechnology in Phytotherapy: Antiinflammatory Effect of a Nanostructured Thymol Gel from Lippia sidoides in Acute Periodontitis in Rats.

Lippia sidoides Cham (Verbenaceae) is largely distributed in the northeastern region of Brazil. It is popularly known as 'Alecrim-pimenta'. Recent studies have shown that some species of Lippia have interesting pharmacological activities. This study aimed to evaluate the effect of a nanostructured thymol gel (TG) 1.2 mg/g on acute phase of ligature-induced periodontitis model [acute periodontal disease (APD)] in rats. APD was induced in 24 Wistar rats subjected to ligature placement on left molars in maxillae. Animals were treated with TG, immediately after APD induction. Saline-based gel was utilized as negative control and diethylammonium diclofenac gel 10 mg/g was used as positive control. Animals were randomly assigned into the groups. The periodontium and the surrounding gingiva were examined at histopathology, as well as the neutrophil influx into the gingiva was assayed using myeloperoxidase activity levels by ELISA method. TG treatment reduced tissue lesion at histopathology coupled to decreased myeloperoxidase activity production in gingival tissue when compared with the saline gel control group (p < 0.05). The TG gel was able to provide a significant myeloperoxidase decreasing in gingiva tissue confirming to be effective in reducing gingival inflammation in this model.

Comparação entre exercícios perineais e exercícios sexuais como método de tratamento fisioterapêutico na disfunção orgásmica feminina / Comparison of perineal exercises and sexual exercises as a method of physical therapy treatment for female orgasmisc dysfunction

Objetivos: Comparar os exercícios perineais e exercícios sexuais como método de tratamento fisioterapêutico na disfunção orgásmica feminina. Métodos: Comparou-se dois grupos: exercícios sexuais (ES) e exercícios sexuais e perineais (ESP). Após a anamnese, avaliou-se a função muscular do assoalho pélvico através das escalas AFA e Esquema PERFECT e foi preenchido o questionário "Quociente Sexual - Versão Feminina". As pacientes do grupo ES receberam um folheto explicativo com exercícios que deveriam seguir três vezes ao dia, retornando ao ambulatório para reavaliação. Já as pacientes do grupo ESP, além de receberem as mesmas orientações do grupo ES, passaram por protocolos de exercícios perineais. Passadas as semanas de exercícios perineais, a paciente retornou para responder ao "QS-F" e passou pela avaliação final do assoalho pélvico. Resultados: Foram incluídas 14 pacientes, sendo cinco no grupo ES e nove no grupo ESP. Nossos achados demonstraram que 80% das pacientes do grupo ES conseguiram alcançar o orgasmo através da masturbação, e 40% das pacientes do mesmo grupo conseguiram alcançar o orgasmo na masturbação na presença do companheiro, enquanto este número oscilou de 11,1 a 22,2% no grupo ESP. Com relação à avaliação da função muscular, os resultados mostraram que houve aumento. Conclusões: A educação sexual é de extrema importância no tratamento da anorgasmia. A masturbação e o estímulo à fantasia são imprescindíveis para o conhecimento dos pontos eróticos. O programa de reabilitação do assoalho pélvico melhora a força muscular perineal, a sensibilidade e consciência perineal, e o prazer genital durante a penetração, além da qualidade sexual, comprovado pelo QS-F.

Effects of a transdermal testosterone metered-dose nanoemulsion in peri- and postmenopausal women: a novel protocol for treating low libido / Efeitos de nanoemulsãom transdérmica dosimetrada de testosterona em mulheres peri-e pós-menopausa: um novo protocolo para o tratamento de libido reduzido

OBJECTIVE: To investigate the efficacy of a transdermal nanoemulsion testosterone associated with transdermal estrogen therapy as a novel protocol treatment for emergent loss of libido. METHODS: Twenty-four women, aged 31-75 years (mean age, 51.7), with emergent loss of libido were allocated to treatment with a novel transdermal formulation of 500 µg/day of testosterone (Biolipid/B2®-testosterone) for 12 weeks, as part of an open label prospective study on peri- and post-menopausal women. Subjects applied the formulation on the right forearm. Clinical and laboratorial parameters including the sexual complaints; serum concentrations of testosterone, insulin, C-reactive protein, weight, blood pressure; body mass index and waist circumference were compared between baseline and 12 weeks after treatment. RESULTS: The mean total serum testosterone increased significantly (p = 0.009) after 12 weeks of treatment. No adverse or androgenic events were observed. There were positive and significant differences (p < 0.05) on sexual complaints, blood pressure, body mass index and waist circumference after transdermal nanoemulsion testosterone treatment. CONCLUSION: This protocol is effective in increasing testosterone levels in peri- and postmenopausal women with low libido.

OBJETIVO: Investigar a eficácia de uma nanoemulsão transdérmica de testosterona associada à terapia com estrogênio transdérmico como tratamento para a perda emergente da libido. MÉTODOS: Vinte e quatro mulheres, com idade entre 31-75 anos (idade média de 51,7), com perda emergente de libido foram incluídas num protocolo para tratamento de libido reduzida com uma formulação transdérmica de 500 µg/dia de testosterona (biolípido/B2®-testosterona) com 12 semanas de duração, como parte de um estudo prospectivo aberto em mulheres peri- e pós-menopausa. As participantes aplicaram a formulação no antebraço direito. Os parâmetros clínicos e laboratoriais, incluindo as queixas sexuais foram comparados entre os valores iniciais e 12 semanas após o tratamento. Mediram-se as concentrações séricas de testosterona, insulina, proteína C-reactiva, o peso, a pressão arterial; o índice de massa corporal e a circunferência da cintura. RESULTADOS: A média de testosterona total no soro aumentou significativamente (p = 0,009) após 12 semanas de tratamento. Não foram observados efeitos adversos ou androgênicos. Registraram-se reduções significativas (p < 0,05) sobre as queixas sexuais, da pressão arterial, do índice de massa corporal e da circunferência da cintura após o tratamento transdérmico com nanoemulsão de testosterona. CONCLUSÃO: O protocolo mostrou eficacia em aumentar os níveis de testosterona em e melhorar a libido em mulheres peri e pós-menopausa com baixa libido.

Dealing with female sexuality: training, attitude, and practice of obstetrics and gynecology residents from a developing country.

INTRODUCTION: There is little research on how obstetrics and gynecology (Ob/Gyn) residents deal with female sexuality, especially during pregnancy. AIM: The aim of this study was to assess the training, attitude, and practice of Ob/Gyn residents about sexuality. METHODS: A cross-sectional survey of Brazilian Ob/Gyn residents enrolling in an online sexology course was conducted. A questionnaire assessed their training in sexuality during medical school and residency and their attitude and practice on sexual issues during pregnancy. MAIN OUTCOME MEASURES: Training, attitude, and practice of Ob/Gyn residents regarding sexuality were the main outcome measures. RESULTS: A total of 197 residents, from 21 different programs, answered the online questionnaire. Mean age was 27.9 ± 2.2, most were female (87%), single (79%), and had graduated in the last 5 years (91%). Almost two-thirds (63%) stated that they did not receive any training at all and 28% reported having only up to 6 hours of training about sexuality in medical school. Approximately half of the respondents (49%) stated that they had received no formal training about sexuality during their residency up to that moment and 29% had received ≤6 hours of training. Over half (56%) never or rarely took a sexual history, 51% stated that they did not feel competent or confident to answer their pregnant patients' questions about sexuality, and 84% attributed their difficulties in dealing with sexual complaints to their lack of specific knowledge on the topic. CONCLUSION: The vast majority of Brazilian Ob/Gyn residents enrolling in a sexuality course had little previous formal training on this topic in medical school and during their residency programs. Most residents do not take sexual histories of pregnant patients, do not feel confident in answering questions about sexuality in pregnancy, and attribute these difficulties to lack of knowledge. These findings point to a clear need for additional training in sexuality among Brazilian Ob/Gyn residents.

Poor-fit indexes of Kupperman index: a psychometric analysis based on item response theory.

OBJECTIVE: This study aims to test the construct validity of the 11 items of the Kupperman index (KI), which has been pioneering in its attempt to quantify climacteric symptoms. METHODS: Unidimensional confirmatory factor analysis of the 11 graded items (hot flashes, paresthesia, insomnia, nervousness, melancholia, vertigo, weakness, arthralgia or myalgia, headache, palpitations, and formication), using a four-point scale (0, none; 4, severe), was used to evaluate the KI in a sample consisting of 84 women with a mean (SD) age of 54.34 (4.00) years who have been in menopause for a mean (SD) of 4.36 (2.53) years. RESULTS: The KI returned poor results on unidimensional model testing (root-mean-square error adjustment, 0.109; 90% CI, 0.075-0.142; comparative fit index, 0.871; Tucker Lewis index, 0.838; weighted root-mean-square residual, 0.971; χ(2)(44) = 87.599; P < 0.001), indicating that the set of items does not properly evaluate the underlying phenomena (climacteric symptoms). CONCLUSIONS: Our study verifies the poor fit of the KI and provides psychometric evidence that KI items warrant revision and/or that the concept underlying climacteric symptoms should be revisited.
