Assessing a cut-off point for the diagnosis of abnormal uterine bleeding using the Menstrual Bleeding Questionnaire (MBQ): a validation and cultural translation study with Brazilian women

ABSTRACT BACKGROUND: Abnormal uterine bleeding (AUB) is a common condition, and the Menstrual Bleeding Questionnaire (MBQ) is used for its assessment. OBJECTIVES: To translate, assess the cut-off point for diagnosis, and explore psychometric properties of the MBQ for use in Brazilian Portuguese. DESIGN AND SETTING: Prospective cohort study including 200 women (100 with and 100 without AUB) at a tertiary referral center. METHODS: MBQ translation involved a pilot-testing phase, instrument adjustment, data collection, and back-translation. Cut-off point was obtained using receiver operating curve analysis. Menstrual patterns, impact on quality of life due to AUB, internal consistency, test-retest, responsiveness, and discriminant validity were assessed. For construct validity, the Pictorial Blood Assessment Chart (PBAC) and World Health Organization Quality of Life - abbreviated version (WHOQOL-BREF) were applied. RESULTS: Women with AUB were older, had higher body mass indices, and had a worse quality of life during menstruation. Regarding the MBQ's psychometric variables, Cronbach's alpha coefficient was > 0.70 in all analyses, high intraclass correlation coefficient was found in both groups; no ceiling and floor effects were observed, and construct validity was demonstrated (correlation between MBQ score, PBAC score, and clinical menstrual cycle data). No difference between MBQ and PBAC scores were perceived after the test-retest. Significant differences were found between MBQ and PBAC scores before and after treatment. An MBQ score ≥ 24 was associated with a high probability of AUB; accuracy of 98%. CONCLUSION: The MBQ is a reliable questionnaire for Brazilian women. The cut-off ≥ 24 shows high accuracy to discriminate AUB.

Cardiovascular Risk Factors in Premature Ovarian Insufficiency using Hormonal Therapy / Fatores de risco cardiovascular na insuficiência ovariana prematura em uso de terapia hormonal

Abstract Objective Premature ovarian insufficiency (POI) is characterized by early hypoestrogenism. An increased risk of cardiovascular (CV) disease is a long-term consequence of POI. A challenge of hormone therapy (HT) is to reduce the CV risk. Methods Cross-sectional study with lipid profile analysis (total cholesterol, LDL-C, HDL-C, VLDL-C and triglycerides), blood glucose levels and arterial blood pressure of women with POI using HT, compared with age and BMI-matched women with normal ovarian function (controls). Results The mean age and BMI of 102 POI patients using HT and 102 controls were 37.2 ± 6.0 and 37.3 ± 5.9 years, respectively; 27.0 ± 5.2 and 27.1 ± 5.4 kg/m2. There wasn't difference between groups in arterial systolic and diastolic blood pressure, blood glucose levels, total cholesterol, LDL-C, VLDL-C and triglycerides. HDL-C levels were significantly higher in the POI group (56.3 ± 14.6 and 52 ± 13.9mg/dL; p = 0.03). Arterial hypertension was the most prevalent chronic disease (12% in the POI group, 19% in the control group, p = ns), followed by dyslipidemia (6 and 5%, in POI and control women). Conclusion Women with POI using HT have blood pressure levels, lipid and glycemic profile and prevalence of hypertension and dyslipidemia similar to women of the same age and BMI with preserved gonadal function, in addition to better HDL levels.

Resumo Objetivo A insuficiência ovariana prematura (IOP) é caracterizada pelo hipoestrogenismo precoce. Risco aumentado de doença cardiovascular (CV) é uma consequência a longo prazo da IOP e um desafio da terapia hormonal (TH) é reduzir o risco CV. Métodos Estudo transversal com análise do perfil lipídico (colesterol total, LDL-C, HDL-C, VLDL-C e triglicerídeos), glicemia e pressão arterial de mulheres com IOP em uso de TH, em comparação a mulheres com função ovariana normal (controles) pareadas por idade e IMC. Resultados A média de idade e IMC de 102 pacientes com IOP em uso de TH e 102 controles foi de 37,2 ± 6,0 e 37,3 ± 5,9 anos, respectivamente; 27,0 ± 5,2 e 27,1 ± 5,4 kg/m2. Não houve diferença entre os grupos na pressão arterial sistólica e diastólica, glicemia, colesterol total, LDL-C, VLDL-C e triglicerídeos. Os níveis de HDL-C foram significativamente maiores no grupo IOP (56,3 ± 14,6 e 52 ± 13,9mg/dL; p = 0,03). A hipertensão arterial foi a doença crônica mais prevalente (12% no grupo POI, 19% no grupo controle, p = ns), seguida da dislipidemia (6 e 5%, no grupo POI e controle). Conclusão Mulheres com IOP em uso de TH apresentam níveis pressóricos, perfil lipídico e glicêmico e prevalência de hipertensão e dislipidemia semelhantes às mulheres da mesma idade e IMC com função gonadal preservada, além de melhores níveis de HDL.

Abnormal uterine bleeding in reproductive age: a comparative analysis between the five Brazilian geographic regions

SUMMARY OBJECTIVE: This study aimed to comparatively evaluate the presence of abnormal uterine bleeding and associated factors among women from the five official Brazilian geographic regions. METHODS: This is a cross-sectional, population-based, multicenter study of reproductive-age women from the five regions of Brazil. All participants answered questionnaires containing personal and socioeconomic data and information on uterine bleeding (self-perception and objective data). RESULTS: A total of 1,761 Brazilian women were included, 724 from the Southeast, 408 from the Northeast, 221 from the South, 213 from the North, and 195 from the Central-West. Considering women's self-perception, the prevalence of abnormal uterine bleeding was 37.56% in the North region, 39.46% in the Northeast, 21.54% in the Central-West, 29.56% in the Southeast, and 25.34% in the South (p<0.001). Abnormal uterine bleeding was more prevalent in the North and Northeast, where women had lower purchasing power, became pregnant more often, and were the only ones financially responsible for supporting the family more often (p<0.001). The menstrual cycle lasted <24 days in less than 20% of the women in all regions (p=NS). Among these, approximately 8 out of 10 women had never undergone treatment in four out of the five regions evaluated. More than half of the evaluated women reported a worsening of their quality of life during bleeding. CONCLUSION: The prevalence of abnormal uterine bleeding in Brazilian women was higher in the North and Northeast, followed by the Southeast, South, and Central-West regions. There was a worsening of quality of life during menstruation regardless of the woman's self-perception of abnormal uterine bleeding. Such results can direct the actions of health managers toward a better approach to abnormal bleeding.

Maternal and perinatal outcomes of pregnancies complicated by chronic hypertension followed at a referral hospital / Resultados maternos e perinatais de gestantes hipertensas crônicas acompanhadas em pré-natal especializado

Abstract Objective To assess maternal and perinatal outcomes of pregnancies in women with chronic hypertension (CH). Methods Retrospective cohort of women with CH followed at a referral center for a 5 year period (2012-2017). Data were obtained from medical charts review and described as means and frequencies, and a Poisson regression was performed to identify factors independently associated to the occurrence of superimposed preeclampsia (sPE). Results A total of 385 women were included in the present study; the majority were > than 30 years old, multiparous, mostly white and obese before pregnancy. One third had pre-eclampsia (PE) in a previous pregnancy and 17% of them had organ damage associated with hypertension, mainly kidney dysfunction. A total of 85% of the patients used aspirin and calcium carbonate for pre-eclampsia prophylaxis and our frequency of sPE was 40%, with an early onset (32.98 ± 6.14 weeks). Of those, 40% had severe features of PE, including 5 cases of HELLP syndrome; however, no cases of eclampsia or maternal death were reported. C-section incidence was high, gestational age at birth was 36 weeks, and nearly a third (115 cases) of newborns had complications at birth One third of the women remained using antihypertensive drugs after pregnancy. Conclusion Chronic hypertension is related with the high occurrence of PE, C-sections, prematurity and neonatal complications. Close surveillance and multidisciplinary care are important for early diagnosis of complications.

Resumo Objetivo Avaliar os resultados maternos e perinatais em gestação de mulheres com hipertensão crônica. Métodos Coorte retrospectiva de mulheres hipertensas crônicas acompanhadas em hospital de referência por 5 anos (2012-2017). Foi realizada revisão dos prontuários médicos e os resultados são descritos em médias e frequências. A regressão de Poisson foi usada para identificar os fatores independentemente associados à ocorrência de pré-eclâmpsia superajuntada. Resultados Um total de 385 mulheres foram incluídas no presente estudo, e amaioria tinha idade > 35 anos, era multípara, majoritariamente brancas e obesas antes da gravidez. Um terço teve pré-eclâmpsia em gestação anterior, e 17% apresentavam lesão de órgão-alvo associada à hipertensão, majoritariamente disfunção renal. Um total de 85% das pacientes usaram ácido acetilsalicílico e carbonato de cálcio para a profilaxia de pré-eclâmpsia, sendo que a frequência de pré-eclâmpsia superajuntada foi de 40%, com um início prematuro (32.98 ± 6.14 semanas). Destas, 40% apresentaram sinais de gravidade associados à pré-eclâmpsia, com 5 casos de síndrome HELLP; entretanto sem nenhum caso de eclampsia ou morte materna. A incidência de cesárea foi alta, comidade gestacional de 36 semanas ao parto, e umterço dos recém-nascidos tiveram complicações ao nascimento. Um terço das mulheres permaneceu usando medicamentos anti-hipertensivos ao fim da gravidez. Conclusão A hipertensão crônica se relaciona comalta prevalência de pré-eclâmpsia, cesárea, prematuridade e complicações neonatais. Vigilância e cuidado multidisciplinar são importantes para o diagnóstico precoce das complicações.

Cognitive abilities screening instrument-short form, mini-mental state examination and functional activities questionnaire in the illiterate elderly / Triagem de habilidades cognitivas em idosos analfabetos: CASI-S, mini-exame do estado mental e questionário de atividades funcionais

Dementia prevalence is increasing in developing countries due to population aging. Brief tests for assessing cognition and activities of daily living are very useful for the diagnosis of dementia by the clinician. Low education, particularly illiteracy, is a hindrance to the diagnosis of dementia in several regions of the world. OBJECTIVES: To compare the Brazilian version of the Cognitive Abilities Screening Instrument-Short Form (CASI-S) with the Mini-Mental State Examination (MMSE) and Pfeffer Functional Activities Questionnaire (PFAQ) for the diagnosis of dementia in illiterate elderly. METHODS: A cross-sectional study with illiterate elderly of both genders seen at the outpatient clinics of the Institute of Gerontology and Geriatrics Jundiaí, São Paulo state was performed. Spearman's correlation coefficient was used to correlate CASI-S, MMSE and PFAQ scores.RESULTS: The sample comprised 29 elderly over 57 years old whose mean scores on the CASI-S (scores ranging from 3 to 23) and the MMSE (scores ranging from 2 to 23) were 11.69 and 12.83, respectively. There was a strong significant correlation between the CASI-S and MMSE (r=0.75, p<0.001) and a moderate correlation coefficient that was significant and negative between the PFAQ and CASI-S (r= -0.53 p=0.003),similar to that between the MMSE and PFAQ (r= -0.41 p=0.025).CONCLUSION: The Brazilian version of the CASI-S demonstrates ease of application and correction in the illiterate elderly, and warrants further studies regarding its applicability for the diagnosis of dementia in populations with a heterogeneous educational background.

A prevalência de demência está aumentando nos países em desenvolvimento, devido ao envelhecimento da população. Testes breves para a avaliação da cognição e atividades de vida diária são muito úteis para o diagnóstico de demência pelo médico. Baixa escolaridade, especialmente analfabetismo, é um obstáculo para o diagnóstico de demência em diversas regiões do mundo. OBJETIVOS: Comparar a versão brasileira do teste Casi-S com o Mini Exame do Estado Mental (MMSE) e Questionário de Atividades Funcionais de Pfeffer (QAFP) para o diagnóstico de demência de analfabetos idosos. MÉTODOS: Estudo de corte transversal, com idosos de ambos os sexos, analfabetos, atendidos no Instituto de Geriatria e Gerontologia do município de Jundiaí, São Paulo. Foi utilizado o coeficiente de correlação de Spearman. RESULTADOS: A amostra foi composta por 29 idosos analfabetos, com médias de escore no Casi-S e no MEEM de 11,69 (variando de 3 a 23 pontos) e 12,83 (variando entre 2 a 23 pontos), respectivamente. Observou-se uma correlação forte e significativa entre o Casi-S e o MEEM (r=0,75; p<0,001) e um coeficiente de correlação moderado, significativo e negativo entre o Casi-S e o QAFP (r= -0,53; p=0,003), o que foi semelhante ao observado entre o MEEM e o QAFP (r= -0.41 p=0.025). Nota-se, portanto, uma correlação importante entre o MEEM e o Casi-S e valores moderados e significativos entre o desempenho cognitivo e o comprometimento nas atividades de vida diária.CONCLUSÃO: Observa-se que o Casi-S é um teste de fácil aplicação e correção, e que merece mais estudos sobre sua aplicabilidade no diagnóstico de demência em populações com heterogeneidade educacional.
