SUMMARY BACKGROUND: Patients with coronavirus disease 2019 on automatic mechanical ventilation have greater heart rate modulation with greater parasympathetic modulation. OBJECTIVE: To analyze the autonomic modulation of heart rate in critically ill patients with coronavirus disease 2019 on invasive mechanical ventilation. METHODS: A cross-section study was carried out with 36 individuals divided into two groups. The control group included patients of both genders, in orotracheal intubation with invasive mechanical ventilation under controlled assisted mode, hospitalized in the intensive care unit for another 24 h. In the non-COVID group, patients diagnosed with coronavirus disease 2019 in the same condition mentioned in the control group. RESULTS: There was a significant increase in heart rate variability (standard deviation of all normal RR intervals recorded at an interval of time; p=0.001; triangular interpolation histogram of RR intervals; p=0.048; and SD2; p=0.014) in the coronavirus disease group compared to the non-COVID group. Successively, the parameters that demonstrate parasympathetic modulation are shown to be higher in the group of patients with coronavirus disease 2019 (root mean square of the square of differences between adjacent normal RR intervals in an interval of time; p<0.001; pNN50; p<0.001; SD1; p=0.002; and high frequency; p=0.022). CONCLUSIONS: There was a greater autonomic modulation of heart rate with a greater parasympathetic modulation in patients with coronavirus disease 2019 on mechanical ventilation.

SUMMARY OBJECTIVES: This study aimed to compare heart rate variability indices in early and late postmenopausal women and assess their correlation and prognostic value to predict late postmenopausal. METHODS: An observational and retrospective study was performed with the medical records of patients from Hospital das Clínicas, Faculdade de Medicina da Universidade de Sao Paulo between 2018 and 2019. We selected medical records of women with menopause, over 40 years old, which were divided into two groups, according to postmenopausal time, i.e., early and late postmenopausal. RESULTS: We analyzed data from 123 women (55 in the early and 68 in the late postmenopausal group). RRtri (triangular index) was lower in the late postmenopausal group (8.68 vs. 7.15, p=0.040). There was a significant weak negative correlation in SDNN, RRtri, and SD2 and postmenopausal time. RRtri presented the potential to predict late postmenopausal. CONCLUSION: The increase in postmenopausal time decreases global heart rate variability indices. The geometric index RRtri was significantly lower in late postmenopausal women and presented the potential to predict late postmenopausal.

Abstract Background: Hypoactive Sexual Desire Disorder (HSDD) is a very prevalent sexual problem, with limited options for treatment. Given that psychological factors are major contributors to the disorder, a therapy such as Cognitive-Behavioral Therapy (CBT) may be useful to treat HSDD. Objective: To evaluate the effects of group CBT on women with HSDD. Method: Clinical trial randomized study with 106 women diagnosed with HSDD, who were divided as follows: Group 1 (n = 53) underwent group CBT for 8-weeks, and Group 2 (n = 53), were put on a waiting list and used as a control group. Sexual function was assessed by the Female Sexual Quotient (FSQQ) at the initial interview and after 6-months. Mann Whitney test was used for group comparison. Main Outcome Measures: demographics, education, sexual history, FSQQ and its domains for sexual function assessment. Results: Both groups had similar characteristics regarding sexual response, self-image, and relationship with a partner at the initial interview. Women undergoing therapy showed significant improvement in sexual function when compared with the control group. The overall FSQQ result showed an average growth of 18.08 points (95% CI 12.87‒23.28) for the therapy group against a decrease of 0.83 points (95% CI 3.43‒1.77) for controls (p < 0.001). The five domains of the questionnaire also exhibited significant improvement in the therapy group: desire and interest (p = 0.003), foreplay (p = 0.003), excitation and tuning (p < 0.001), comfort (p < 0.001), and orgasm and satisfaction (p < 0.001). Conclusion: Group CBT was shown to be an effective tool for treating HSDD.

Abstract Purpose To assess the knowledge of students from public high schools in poor communities about HPV and Sexually Transmitted Infections and their attitude towards and prevention of such diseases. Patients and methods Cross-sectional study with adolescents from public schools of São Paulo - Brazil. Participants were selected for an interview by a randomization program. A questionnaire about knowledge, attitudes, and preventive practices regarding STIs, including HPV, according to sex was administered and answers were analyzed by the Poisson regression model with robust variance. Results Median age of the 269 participants was 16 years. The majority was of African descent (68.8%, n = 185), most (74%, n = 199) were religious and the vast majority (90.7%, n = 244) lived with their parents. The Poisson regression revealed statistically significant sex-related differences regarding the following questions: “Do you know how it is prevented?” (PR = 1.12 [1.03‒1.23], p = 0.007); “Have you ever been concerned with HPV?” (PR = 1.10 [1.02‒1.19], p = 0.011); “Have you ever sought health care due to concerns about HPV?” (PR = 1.09 [1.04‒1.14], p < 0.001); “Do you know what a Pap Smear is?” (PR = 1.24 [1.13‒1.36], p < 0.001); “Do you know what the cervix is?” (PR = 1.23 [1.13‒1.34], p < 0.001); “Do you know what cervical cancer is?” (PR = 1.13 [1.04‒1.22], p = 0.004). Conclusions The present results show that adolescents from public schools in poor communities in São Paulo City know little about HPV and cervical cancer. Male adolescents know less than female adolescents and are less concerned with health care.

SUMMARY OBJECTIVE The aim of this study was to assess cardiac autonomic modulation in postmenopausal women with and without dry eye syndrome (DES) and to identify associations between clinical and socioeconomic factors. METHODS A cross-sectional study was carried out at the Institute of Ocular Surgery of the Northeast (ICONE), Brazil. Convenience sample of postmenopausal women, over 40 years old, who were divided into two groups: with and without DES. Clinical, sociodemographic, and ophthalmological characteristics of these women were assessed. Capture of RR intervals was performed using a cardio frequency meter. Differences between the groups were analyzed using the Chi-square test, the Student’s t test, and the Mann-Whitney test. RESULTS Women with DES were present in 60.4% (n=58), highest median age (63.5 years, 95%CI 62.0–67.9; p<0.001), median length of time menopause (19 years old, 95%CI 10.4–24.0; p<0.001). There was a difference in the standard deviation of all normal-to-normal index between the groups. However, when the differences were adjusted to the clinical model, no association was found between DES and heart rate variability (HRV). CONCLUSIONS The analysis of cardiac autonomic modulation in postmenopausal women is similar in the presence or absence of DES. Clinical factors, time of menopause, and intensity of symptoms were not associated with HRV indices.

Abstract Swyer syndrome is one of the disorders of sexual differentiation. Previous studies have demonstrated increased sympathetic activity with heart rate variability (HRV) analysis with decreasing estradiol levels. One patient presented a pure 46, XY gonadal dysgenesis with female phenotype. Cardiac autonomic modulation was assessed through HRV analysis while at rest. This research analyzed linear and nonlinear indexes. HRV analysis showed reduced parasympathetic and global modulation with an apparent increase in sympathetic tone and a loss of HR fractal dynamics toward correlated behavior, characterized by low entropy and high determinism of time series.

RESUMO OBJETIVO Analisar o nível de conhecimento e aceitabilidade da vacina contra o HPV entre adolescentes vacinados e não vacinados na Amazônia Ocidental. MÉTODOS Estudo transversal com adolescentes de 10 a 19 anos. O instrumento usado para coletar dados contém informações demográficas e socioeconômicas e 27 perguntas que avaliam o conhecimento e a aceitabilidade da vacina contra o HPV. Para comparar a prevalência de adolescentes vacinados com as respostas corretas para perguntas sobre conhecimento, aceitabilidade e vacinação contra o HPV, o modelo de regressão de Poisson de variância robusta foi utilizado no software Stata 13.0. Resultados: Participaram do estudo 190 adolescentes, 60,5% (n=115) na faixa etária de vacinação recomendada pelo governo brasileiro; dentre eles, 53,9% (n=62) relataram não ter sido vacinados (p<0,001). A proporção de resultados corretos entre os adolescentes foi de 78,9% (n=150), que reconheceram o HPV como vírus; 63,7% (n=121) relataram o HPV como causa de câncer do colo do útero. Os participantes que sabem que o HPV é um fator causal no câncer do colo do útero têm 1,94 (IC 1,18-3,18; p=0,009) vez mais chances de terem sido vacinados do que aqueles que não sabem. Entre os entrevistados, as principais fontes de conhecimento sobre a vacina foram escolas (51,6%) e profissionais de saúde (22,6%). CONCLUSÃO Adolescentes não vacinados apresentam lacunas de conhecimento sobre o HPV e sua vacina quando comparados aos vacinados. Nossos resultados enfatizam a necessidade de campanhas eficazes para fornecer informações adequadas sobre o HPV e sua vacina a adolescentes, pais e profissionais de saúde.

SUMMARY PURPOSE To analyze the level of knowledge about and the acceptability of the HPV vaccine among vaccinated and unvaccinated adolescents in the Western Amazon. METHODS A cross-sectional study on adolescents aged 10 to 19 years. The instrument used to collect data contains demographic and socioeconomic information and 27 questions that assess the knowledge and acceptability of the HPV vaccine. To compare the prevalence of vaccinated adolescents with the correct answers to questions about HPV and acceptability and vaccination, the robust variance Poisson regression model was used in the Stata 13.0 software. FINDINGS A total of 190 adolescents participated in the study, 60.5% in the age group of vaccination recommended by the Brazilian government, among them, 53.9% reported not having been vaccinated (p <0.001). A total of 150 (78.9%) adolescents correctly recognized HPV as a virus; 121 (63.7%) recognized HPV as a cause of cervical cancer. Participants who know HPV is a causative factor for cervical cancer are 1.94 times more likely to have been vaccinated than those who do not. Among the interviewees, the main sources of knowledge about the vaccine were schools (51.6%) and health professionals (22.6%). CONCLUSION Unvaccinated adolescents have knowledge gaps about HPV and its vaccine when compared to those vaccinated. Our results emphasize the need for effective campaigns to deliver adequate information about HPV and its vaccine to adolescents, their parents, and health professionals.

RESUMO INTRODUÇÃO A associação entre diagnósticos ginecológicos e sua distribuição nos setores de saúde proporciona benefícios no campo da promoção de saúde e na identificação de temas para educação continuada na assistência. OBJETIVO Identificar os diagnósticos em saúde e o fluxo de encaminhamento de mulheres no climatério. MÉTODO Trata-se de estudo transversal realizado no Ambulatório de Saúde da Mulher do Hospital Universitário da Universidade de São Paulo, de referência em ginecologia e de treinamento para residentes de Medicina de Família e Comunidade, entre 2017-2018. A casuística foi realizada a partir de 274 prontuários de mulheres atendidas e foram processados informações sociodemográficas e clínicas, diagnósticos ginecológicos e distribuição dos serviços de saúde (primário, secundário e terciário). O teste qui-quadrado e razão de chance foram utilizados para estatística. RESULTADOS O tabagismo (OR=2,27, IC95% 1,05;4,89, p=0,035) foi associado ao encaminhamento de mulheres no climatério para a maior complexidade. Em relação aos tipos de diagnóstico, a chance de serem encaminhadas para a média e alta complexidade foi de 135% (OR=1,69, IC95% 0,93;3,08) nos transtornos não inflamatórios do trato genital feminino, 200% (OR=0,98, IC95% 0,23;4,02) nas doenças da mama, 300% (OR=1,51, IC95% 0,47;4,83) nos transtornos inflamatórios do trato genital feminino, sem predomínio entre os diagnósticos. CONCLUSÃO As mulheres climatéricas e na pós-menopausa acima de 50 anos e tabagistas com diagnósticos de transtornos não inflamatórios do trato genital feminino e inflamatórios, bem como doenças da mama, foram as mais direcionadas para ambulatório cirúrgico na média e alta complexidade.

SUMMARY OBJECTIVE The association between gynecological diagnoses and their distribution across healthcare sectors benefits health promotion and the identification of topics for continued education of gynecological care. This study aimed to identify healthcare diagnoses and referral flow in climacteric women. METHODS This is a cross-sectional study conducted at the Women’s Health Clinic of the University Hospital, University of São Paulo, with a reference to gynecology and training for Residents of Family and Community Medicine, between 2017 and 2018. The medical records of 242 women whose sociodemographic and clinical information, gynecological diagnoses, and distribution of healthcare services (primary, secondary, and tertiary) had been processed were collected. Statistical analysis included the chi-square test and odds ratio. RESULTS Smoking (OR = 2.27, 95% CI 1.05–4.89; p = 0.035) was associated with the referral of climacteric women to higher complexity services. Considering the distribution of non-oncological diagnoses in climacteric patients, the chance of women being referred to medium- and high-complexity health services presented a 2-fold increase in cases of breast diseases, a 2.35-fold increase in cases of noninflammatory disorders of the female genital tract, and a 3-fold increase in cases of inflammatory diseases of the pelvic organs. CONCLUSION Climacteric women aged over 55 years, postmenopausal women, and smoking women were most frequently referred to medium- and high-complexity outpatient surgery.

RESUMO A melatonina tem propriedades anti-inflamatórias e antioxidantes que podem influenciar o crescimento e a apoptose dos tecidos. Esse aspecto pode influenciar o sucesso do transplante de órgãos. OBJETIVO Avaliar a relação entre a melatonina e o transplante de órgãos. MÉTODO A revisão sistemática foi realizada nas bases de dados do PubMed, usando os termos de pesquisa: “fisiologia da melatonina” ou “terapêutica da melatonina” e “farmacologia do transplante” ou “fisiologia do transplante” ou “terapêutica do transplante” ou “terapia do transplante”. Não foram incluídos os experimentos sobre os órgãos do sistema reprodutivo. Após análise, cinco artigos foram selecionados após a leitura do título e do resumo de 50 manuscritos. Os trabalhos foram divididos em duas vertentes: a) análise da influência do procedimento de transplante de órgão na produção de melatonina; b) ação da melatonina sobre o transplante de órgãos. RESULTADOS O procedimento cirúrgico do transplante cardíaco, a imunossupressão e o enxerto não influenciaram a secreção de melatonina em roedores, mas houve redução significante da melatonina nos casos do procedimento de transplante renal em pacientes com insuficiência renal. A ministração de melatonina em modelos experimentais diminuiu a rejeição e melhorou o sucesso de transplante. CONCLUSÃO Os estudos mostram que a melatonina pode reduzir a dependência da espécie e do órgão e que o emprego da melatonina diminui a rejeição do órgão.

SUMMARY Melatonin has anti-inflammatory and antioxidant properties that can influence tissue growth and apoptosis. This aspect may influence the success of organ transplantation. OBJECTIVE To evaluate the relationship between melatonin and organ transplantation. METHODS A systematic review was performed in PubMed databases using the search terms: “melatonin physiology” or “melatonin therapy” and “transplant pharmacology” or “transplant physiology” or “transplant therapy” or “Transplant therapy”. Experiments on the organs of the reproductive system were not included. After analysis, five articles were selected after reading the title and abstract of 50 manuscripts. The works were divided into two aspects: a) analysis of the influence of the organ transplantation procedure on melatonin production; b) action of melatonin on organ transplantation. RESULTS The cardiac transplantation surgical procedure, immunosuppression, and graft did not influence melatonin secretion in rodents, but there was a significant reduction of melatonin in the renal transplantation procedure in patients with renal insufficiency. Melatonin administration in experimental models decreased rejection and improved transplant success. CONCLUSION Studies show that melatonin can reduce organ and species dependence, and the use of melatonin decreases graft rejection.

RESUMO O câncer de mama é comum em mulheres, mas sua etiologia ainda não é totalmente compreendida. Vários fatores podem contribuir para sua gênese, genética, estilo de vida e meio ambiente. A melatonina pode estar envolvida no processo de câncer de mama. Portanto, o objetivo deste estudo é avaliar a influência dos níveis de melatonina no câncer de mama por meio de uma revisão sistemática e meta-análise. Realizamos uma revisão sistemática de acordo com as recomendações do Prisma. Os principais bancos de dados, Medline, Embase e Cochrane, foram consultados. Não houve restrição quanto ao ano de publicação e idioma. Os dados de revisão sistemática obtidos de abril de 2017 a setembro a 2017 foram analisados. A meta-análise foi conduzida pelo programa RevMan 5.3 fornecido pela Cochrane Collaboration. De um total de 570 artigos, nove foram incluídos nesta revisão. As análises foram conduzidas em mulheres com câncer de mama e pacientes controle, dos quais 10% e 90% estavam no período reprodutivo e após a menopausa, respectivamente. O nível mais baixo de melatonina foi encontrado em aproximadamente 55% dos estudos com câncer de mama na pós-menopausa. As meta-análises de estudos demonstraram os baixos níveis de melatonina em doentes com câncer da mama (n=963), em comparação com os pacientes de controle (n=1.332), sendo a diferença de médias entre os estudos da −3,54 (CI −6,01, −1,06). Outra diferença é demonstrada nas comparações entre pacientes fumantes, sendo a diferença da média entre 1,80 [0,97-2,63]. Nossos dados sugerem que baixos níveis de melatonina podem ser um fator de risco para câncer de mama.

SUMMARY Breast Cancer is common in women, but its etiology is not yet fully understood. Several factors may contribute to its genesis, such as genetics, lifestyle, and the environment. Melatonin may be involved in the process of breast cancer. Therefore, the aim of this study is to evaluate the influence of the levels of melatonin on breast cancer through a systematic review and meta-analysis. We performed a systematic review according to PRISMA recommendations. The primary databases MEDLINE, Embase, and Cochrane were consulted. There was no restriction on the year of publication and language. Data of systematic reviews from April 2017 to September to 2017 were analyzed. The meta-analysis was conducted using RevMan 5.3 software provided by the Cochrane Collaboration. From a total of 570 articles, 9 manuscripts were included in this review. They analy onzed women with breast cancer and control patients, of which 10% and 90% were in the reproductive period and after menopause, respectively. The lowest level of melatonin was found in approximately 55% of studies with breast cancer in post-menopause. The metanalyses of the studies demonstrated low levels of melatonin in breast cancer patients (n=963) compared with control patients (n= 1332), with a mean difference between the studies of −3.54 (CI −6.01, −1.06). Another difference found was in the comparison between smoking patients, with an average difference between 1.80 [0.97-2.63]. Our data suggest that low levels of melatonin might be a risk factor for breast cancer.

OBJECTIVE: To evaluate the knowledge and acceptability of the human papillomavirus (HPV) vaccine among health professionals from western Amazonia. METHODS: A cross-sectional study was conducted in the Sistema Assistencial è Saúde da Mulher e da Criança (Health Care System for Women and Children; SASMC) in Acre, Brazil, in 2017. The participants comprised 196 health professionals. The data collection instrument contained 31 questions about HPV, its clinical repercussions for women, and the HPV vaccine. Quantitative variables were presented as medians and 95% confidence intervals (CIs), and p<0.05 was considered statistically significant. For the analyses, chi-square tests and Mann-Whitney tests were used. The collected data were analyzed using Stata®11.0. RESULTS: Of the 196 health professionals, 39.8% (n=76) were physicians and 61.2% (n=120) were other health professionals. The interviewees were mostly female (n=143, 73%, 95% CI 66.1 to 78.9%) who worked in the medical field (n=81, 41.3%, 95% CI 34.4 to 48.6%), and the median age was 38 years (95% CI 36.0 to 39.7). Physicians had increased knowledge regarding only the statement "cervical cancer is one of the main causes of cancer in women", with a proportion ratio of 0.88 (0.80; 0.97) and p<0.001. Regarding clinical knowledge of the HPV vaccine, a low proportion of correct answers was obtained for all the questions, and no significant differences were found between the groups. CONCLUSION: Acceptability and knowledge of HPV and its vaccine were similar among health professionals, with knowledge gaps in questions about the relation between smoking and cervical cancer and specific clinical knowledge.

RESUMO OBJETIVO Avaliar dor, capacidade funcional e qualidade de vida de pacientes com dor lombar crônica inespecífica após terapia por exercícios domiciliares, com diferentes maneiras de supervisão. MÉTODO Trinta indivíduos de ambos os sexos, com idade entre 18 e 65 anos, apresentando dor lombar crônica inespecífica, realizaram os exercícios propostos três vezes por semana, durante oito semanas. Indivíduos do Grupo A (N=17) realizaram os exercícios após única sessão supervisionada. Já os indivíduos do Grupo B (N=13) foram supervisionados uma vez por semana no centro de reabilitação. Ambos receberam cartilha com orientações e questionários para avaliar dor, capacidade funcional e qualidade de vida; durante avaliação inicial, após quatro e oito semanas. RESULTADOS Houve melhora da dor e capacidade funcional entre as avaliações inicial e semana 4, e inicial e semana 8 nos dois grupos (p<0,05). Na avaliação de qualidade de vida (SF-36), os critérios de dor, capacidade funcional e aspectos físicos obtiveram melhora significativa após oito semanas (p<0,05). Não houve diferença significativa ao comparar os grupos (p>0,05). CONCLUSÃO A terapia por exercícios domiciliares, quando realizada num período de oito semanas, com auxílio da cartilha, foi eficaz para melhora da dor, capacidade funcional e qualidade de vida, em pacientes com dor lombar crônica inespecífica. A supervisão semanal não influenciou de forma significativa o resultado final quando comparados os grupos.

SUMMARY OBJECTIVE To evaluate pain, functional capacity, and quality of life of patients with non-specific chronic low back pain, after home-based exercise therapy with different kinds of supervision. METHOD Thirty individuals of both gender, between 18 and 65 years old, performed the proposed exercises three times a week, for eight weeks. Group A (N = 17) performed the exercises after a single supervised session. Group B (N = 13) was supervised once a week at the rehabilitation center. Both groups received a booklet with instructions, and questionnaires to evaluate pain, functional capacity and quality of life; during the initial evaluation, after four and eight weeks. RESULTS There was an improvement in pain and functional capacity between the initial evaluation and week 4, and the initial evaluation and week 8 in both groups (p <0.05). In the quality of life evaluation, the criteria for pain, functional capacity, and physical aspects had significant improvement after 8 weeks (p <0.05). There was no difference when comparing groups A and B (p >0,05). CONCLUSION Home-based exercise therapy, when performed in a period of eight weeks, using the booklet, was effective for improving level of pain, functional capacity, and quality of life in patients with non-specific chronic low back pain. The weekly supervision did not significantly influence the final outcome between the groups.
