RESUMO

OBJECTIVES: The objective of this study was to evaluate the relationship between food intake and serum levels of leptin and ghrelin in the luteal (LP) and follicular (FP) phases of the MC (menstrual cycle) in participants with and without PMS (premenstrual syndrome). METHODS: This was a case-control study with healthy participants aged 20-45 years with regular menstrual cycles (24-35 days) with and without PMS. After the Daily Record of Severity of Problems (DRSP) was filled out for two months (PMS diagnosis), a nutritional assessment was carried out based on twelve food intake records (for two menstrual cycles) to quantify food intake. RESULTS: Of the 69 participants analyzed, 35 experienced PMS and 34 did not experience PMS. For participants with PMS, calorie and carbohydrate intake was higher during LP than in FP (p = 0.004 and p = 0.003, respectively), whereas these changes were not observed in participants without PMS (p > 0.05). There were interactions between the groups and the MC phases (LP and FP) for the intake of calories (p = 0.028) and carbohydrates (p = 0.001). There was a marginal negative relationship between the levels of ghrelin and calorie intake in FP (rS = -0.314, p = 0.066) in the PMS group and a negative relationship between the levels of ghrelin and leptin in LP (rS = -0.490, p = 0.004) in the group without PMS. CONCLUSIONS: These results indicated a higher calorie and carbohydrate intake during LP in participants with PMS, in addition to the hypothesis that the roles of ghrelin and leptin in energy regulation may be different in participants with PMS compared to those without PMS.

RESUMO

Low doses of sulpiride have been used off-label to treat menopausal hot slashes in Southern Brazil despite limited scientific evidence. This randomized controlled trial aimed at assessing the effects of sulpiride as compared to placebo on the frequency and severity of hot flashes. Postmenopausal women, aged 47-62, were recruited from the Menopause Clinic at Hospital de Clínicas de Porto Alegre, Rio Grande do Sul, Brazil, between March 2016 and January 2017. After a baseline assessment of 4 weeks, women were included if they had at least a mean of five moderate to severe hot flashes per day and then randomized to receive for 8 weeks either placebo (n= 14) or sulpiride 50 mg/d (n= 14). The number and severity of hot flashes were evaluated after the 8-week intervention. A generalized estimating equations (GEE) model with Bonferroni correction was used to simultaneously assess the frequency and severity of hot flashes. Baseline frequency and severity of hot flashes/day were similar in both groups. Sulpiride significantly reduced the total weekly mean of hot flash frequency (GEE, pinteraction=.019) and the total weekly mean of severity scores (GEE, pinteraction=.09, pgroup=.006, ptime≤.0001) after 4 and 8 weeks of treatment. Treatment with sulpiride 50 mg/d significantly reduced the frequency and severity of hot flashes. Further studies are needed to confirm its benefits and related mechanisms of action.

RESUMO

Dyspareunia negatively affects women´s quality of life, and is a frequent complaint during the peri- and postmenopausal period. A randomized trial evaluated sexual function, quality of life, pain, and pelvic floor muscle function of climacteric women aged between 40 and 60 years old who were sexually active and had complaints of dyspareunia for at least six months. They were assessed before and after their randomization in one of the following interventions: the first group (n = 21) received five one-hour sessions of thermotherapy for relaxation of pelvic floor muscles, myofascial release, and pelvic training (pelvic floor muscle training-PFMT group). The second group (n = 21) received five one-hour sessions during which heat was applied to the lower back with myofascial release of abdominal diaphragm, piriformis, and iliopsoas muscles, with no involvement of pelvic training (lower back-LB group). Forty-two climacteric women with dyspareunia (mean ± SD, PFMT group: 51.9 ± 5.3 years, LB group: 50.6 ± 4.7 years, Student's t-test, p = 0.397) were studied. Pain scores (mean ± SEM) in the PFMT group decreased from 7.77 ± 0.38 to 2.25 ± 0.30; and in the LB group from 7.62 ± 0.29 to 5.58 ± 0.49 (generalized estimating equation-GEE model, p ≤ 0.001 for group, time, and interaction pairwise comparisons). Conclusion: The proposed pelvic floor muscle training protocol was effective to improve pain, quality of life, sexual function, and pelvic floor muscle function in climacteric women with dyspareunia.

RESUMO

Trisomy 18 (T18) and trisomy 13 (T13) are polymalformative syndromes associated with a high rate of spontaneous abortions, intrauterine death, and short postnatal life. This study describes the overall outcome in a country where the therapeutic interruption of pregnancy is not available. The medical records of women with prenatal diagnosis of full trisomy of T13 or T18 between October 1994 and October 2017 were analyzed in order to describe their natural outcomes. Thirteen cases of T13 and 29 cases of T18 were included. The miscarriage rate was 9% for T18 and no cases for T13. Intrauterine fetal death occurred in 46% and 52% of cases for T13 and T18, respectively. The rate of live births for T13 was 54%, and the median survival was one day (95% CI -33.55 - 90.40) and 71% died in the first 24 hours of life. The rate of live births for T18 was 37% and the median survival was two days (95% CI -1.89 - 13.17); 90% of the affected babies died within first week of life. For the affected babies reaching the first year of life and for those who lived longer, multiple invasive and expensive procedures were required, without success in prolonging life beyond 180 days. This large series provides information for professionals and women regarding the natural histories of T13 and T18. Results of this study are consistent with those referenced in the literature, emphasizing the need of structured protocols and guidelines aiming early T13 and T18 diagnosis, prenatal care, gestation/parents follow-up, and counseling processes. For those couples with earlier diagnosis, a better follow-up and counseling during the prenatal care lead to the option for a support or palliative management of the newborn. Finally, when the counseling process is appropriate, it becomes easier to take decisions respecting the parent's autonomy and to look for better outcomes for both, the mother and the fetus.

RESUMO

During aging, there is a marked decline in the antioxidant capacity of brain tissue, leading to a gradual loss of the antioxidant/oxidant balance, which causes oxidative damage. The effects of Paullinia cupana Mart. extract, which is described as being rich in caffeine and many polyphenol compounds, on the central nervous system have not been extensively investigated. The aim of this study was to therefore investigate the effect of a commercial guarana extract (CGE) on cognitive function, oxidative stress, and brain homeostasis proteins related to cognitive injury and senescence in middle age, male Wistar rats. Animals were randomly assigned to a group according to their treatment (saline, CGE, or caffeine). Solutions were administered daily by oral gavage for 6 months. Open field and novel object recognition tasks were performed before and after treatment. Biochemical analyses were carried out on the hippocampus and striatum. Our open field data showed an increase in exploratory activity and a decrease in anxiety-like behavior with caffeine but not with the CGE treatment. In the CGE-treated group, catalase activity decreased in the hippocampus and increased in the striatum. Analyses of the hippocampus and striatum indicate that CGE and/or caffeine altered some of the analyzed parameters in a tissue-specific manner. Our data suggest that CGE intake does not improve cognitive development, but modifies the oxidative stress machinery and neurodegenerative-signaling pathway, inhibiting pro-survival pathway molecules in the hippocampus and striatum. This may contribute to the development of unfavorable microenvironments in the brain and neurodegenerative disorders.

RESUMO

Chronic dietary long-chain polyunsaturated fatty acids (PUFAs) deficiency may lead to changes in cortex and hippocampus neuronal membrane phospholipids, and may be linked to impaired central nervous system function. Particularly docosahexaenoic acid deficiency appears to be involved in neuropsychiatric disorders. On the other hand, adverse events early in life may also profoundly affect brain development, leading to long-lasting effects on neurophysiology, neurobiology and behavior. This research assessed if neonatal stress and a dietary n-3 PUFAs deficiency could interact to produce hippocampal alterations related to mitochondrial functions in adult rats. There were no effects of diet, neonatal intervention or interactions on superoxide dismutase or catalase enzymatic activities, mitochondrial membrane potential and respiratory chain complexes. Rats fed n-3 PUFAs deficient diet displayed higher levels of glutathione peroxidase and catalase activity, higher free radicals production and higher thiol content compared to rats fed n-3 PUFAs adequate diet. There were interactions among diets and neonatal stress, since glutathione peroxidase, free radicals production and thiol content were increased in groups that were subjected to neonatal interventions fed n-3 PUFAs deficient diet. Additionally, reduced mitochondrial potential was observed in handled animals. Total thiol revealed a neonatal stress effect, since animals subjected to neonatal interventions displayed lower thiol content. In conclusion, we observed that a chronic treatment with deficient n-3 PUFAs diet, from the puberty period on, increased free radicals production and imbalanced antioxidant enzymes activities, and these increases were higher in animals subjected to neonatal interventions.

RESUMO

BACKGROUND: Although several studies have reported an association between mental disorders and serum levels of brain-derived neurotrophic factor (BDNF), this association is still poorly understood. The study of factors associated with both BDNF levels and mental disorders, such as n-3 polyunsaturated fatty acids (n-3 PUFAs), may help to elucidate the mechanisms mediating the relationship between the two variables. Therefore, the present study aimed to evaluate whether the intake n-3 PUFAs correlates with serum levels of BDNF. FINDINGS: This study involved 137 adolescents drawn from a community sample, including a group with high levels of anxiety, assessed using the Screen for Children and Anxiety Related Emotional Disorders. Blood samples were collected and serum BDNF levels were measured. n-3 PUFAs were estimated using a food frequency questionnaire for adolescents. Correlations were performed to assess the association between n-3 PUFAs intake and BDNF levels. Effects of potential confounders (total fat consumption, age, gender and anxiety) were examined using linear regression models. There was a direct correlation between n-3 PUFAs consumption and serum BDNF levels, which remained significant even after accounting for potential confounders. CONCLUSIONS: We were able to detect a correlation between n-3 PUFAs intake and peripheral BDNF levels. Our study was limited by its small sample size, and our external validity may be restricted by the oversampling of anxious adolescents. Our findings may help determine the nature of the association between mental disorders and serum levels of BDNF. However, more studies are needed to elucidate the possible mechanisms by which n-3 PUFAs intake affects BDNF levels, and how this may lead to an increased vulnerability to psychiatric disorders.

RESUMO

Objective: To validate the 10-item Cervantes Scale (CS-10) among Brazilian women. Methods: This is a cross-sectional observational study involving women in the community aged 40-55 years in the Southern region of Brazil. They completed a general health, habits and socio-demographic questionnaire, the CS-10 and the Women's Health Questionnaire (WHQ). Women unable to understand the survey, not consenting to participate, or having incapacity imposing difficulties during the completion of the questionnaire were excluded. A Confirmatory Factor Analysis (CFA) was conducted with the AMOS 16.0 software. Chi-square of degrees of freedom (χ2/df), the Comparative Fit Index (CFI), the Tucker-Lewis Index (TLI) and the Root-Mean-Square Error of Approximation (RMSEA) were used as indices of goodness of fit. Cronbach's alpha coefficient was used for internal consistency. Results: A total of 422 women were included (premenopausal n=35, perimenopausal n=172, postmenopausal n=215). The CFA for the CS-10 showed a good fit (χ²/df=1.454, CFI=0.989; TLI=0.985; RMSEA=0.033; CI 90%=0.002-0.052; PCLOSE=0.921; Model p=0.049). Good reliability was established in CS-10 and WHQ (Cronbach's alpha=0.724). Postmenopausal women had higher total CS-10 scores (p≤0.0001), reflecting worse quality of life (QoL) related to menopause symptoms and confirming the greater symptomatology evaluated by high total scores for WHQ found in this population when compared to those in the premenopausal period (p=0.041). Conclusion: The CS-10 is a consistent tool for health-related QoL in Brazilian mid-aged women.

RESUMO

PURPOSE: To evaluate recurrence rates and risk factors among women with stage IA1 cervical cancer without lymph vascular space invasion managed conservatively. METHODS: retrospective review of women with stage IA1 squamous cervical cancer who underwent cold knife cone or loop electrosurgical excision procedure, between 1994 and 2015, at a gynecologic oncology center in Southern Brazil. Age at diagnosis, pre-conization findings, conization method, margin status, residual disease, recurrence and survival rates were collected and analyzed. RESULTS: 26 women diagnosed with stage IA1 squamous cervical cancer without lymphovascular space invasion underwent conservative management and had at least 12 months follow-up. The mean follow-up was 44.6 months. The mean age at diagnosis was 40.9 years. Median first intercourse occurred at age 16 years, 11.5% were nulliparous and 30.8% were current or past tobacco smokers. There was one Human immunodeficiency virus positive patient diagnosed with cervical intraepithelial neoplasia grade 2 at 30 months after surgery. However, there were no patients diagnosed with recurrent invasive cervical cancer and there were no deaths due to cervical cancer or other causes in the cohort. CONCLUSION: Excellent outcomes were noted in women with stage IA1 cervical cancer without lymphovascular space invasion and with negative margins who were managed conservatively, even in a developing country.

RESUMO

BACKGROUND: In the last twenty years, retrospective studies have shown that perinatal events may impact the individual health in the medium and long term. However, only a few prospective studies were designed to address this phenomenon. This study aims to describe the design and methods of the Impact of Perinatal Environmental Variations in the First Six Months of Life - the IVAPSA Birth Cohort. METHOD/DESIGN: This is a clinical study and involves the recruitment of a birth cohort from hospitals in Porto Alegre, Rio Grande do Sul, Brazil. Mothers from different clinical backgrounds (hypertensive, diabetics, smokers, having an intrauterine growth restricted child for idiopathic reasons, and controls) will be invited to join the study twenty-four hours after the birth of their child. Data on economic, social, and maternal health care, feeding practices, anthropometric measures, physical activity, and neuropsychological evaluation will be obtained in interviews at postpartum, 7 and 15 days, 1, 3 and 6 months of life. DISCUSSION: To our knowledge, this is the first thematic cohort focused on the effects of intrauterine growth restriction to prospectively enroll mothers from different clinical backgrounds. The IVAPSA Birth Cohort is a promising research platform that can contribute to the knowledge on the relationship between perinatal events and their consequences on the children's early life.

RESUMO

Nutrition in pregnancy, during lactation, childhood, and later stages has a fundamental influence on overall development. There is a growing research interest on the role of key dietary nutrients in fetal health. Omega-3 polyunsaturated fatty acids (n-3 LCPUFAs) play an important role in brain development and function. Evidence from animal models of dietary n-3 LCPUFAs deficiency suggests that these fatty acids promote early brain development and regulate behavioral and neurochemical aspects related to mood disorders (stress responses, depression, and aggression and growth, memory, and cognitive functions). Preclinical and clinical studies suggest the role of n-3 LCPUFAs on neurodevelopment and growth. n-3 LCPUFAs may be an effective adjunctive factor for neural development, growth, and cognitive development, but further large-scale, well-controlled trials and preclinical studies are needed to examine its clinical mechanisms and possible benefits. The present paper discusses the use of n-3 LCPUFAs during different developmental stages and the investigation of different sources of consumption. The paper summarizes the role of n-3 LCPUFAs levels during critical periods and their effects on the children's neurodevelopment, nutrition, and growth.

RESUMO

The SARS-CoV-2 variant of concern (VOC) gamma (P.1) has increased transmissibility and resulted in elevated hospitalization and mortality rates in Brazil. We investigated the clinical course of COVID-19 caused by gamma and non-VOCs at a reference hospital in Brazil in a retrospective cohort study with nonelderly hospitalized patients from two periods, before and after the emergence of gamma. Cohort 1 included patients from both periods whose samples would be eligible for whole-genome sequencing (WGS). Cohort 2 was composed of randomly selected patients from Cohort 1 whose samples were submitted to WGS. A total of 433 patients composed Cohort 1: 259 from the first and 174 from the second period. Baseline characteristics were similar, except for a higher incidence of severe distress respiratory syndrome at admission in patients from the second period. Patients from the second period had significantly higher incidence rates of advanced respiratory support (adjusted hazard ratio [aHR]: 2.04; 95% confidence interval [CI], 1.60-2.59), invasive ventilatory support (aHR: 2.72; 95% CI: 2.05-3.62), and 28-day mortality from the onset of symptoms (aHR: 2.62; 95% CI: 1.46-4.72). A total of 86 (43 gamma and 43 non-gamma) patients composed Cohort 2. Patients with confirmed gamma VOC infections had higher advanced ventilatory support and mortality rates than non-gamma-infected patients. Our study suggests that non-elderly patients hospitalized for COVID-19 in the second period (used as a proxy of gamma infection) had a more severe clinical course. This might have contributed to higher hospitalization and death rates observed in the second wave in Brazil.

RESUMO

Point-of-care serological tests for SARS-CoV-2 have been used for COVID-19 diagnosis. However, their accuracy over time regarding the onset of symptoms is not fully understood. We aimed to assess the accuracy of a point-of-care lateral flow immunoassay (LFI). Subjects, aged over 18 years, presenting clinical symptoms suggestive of acute SARS-CoV-2 infection were tested once by both nasopharyngeal and oropharyngeal RT-PCR and LFI. The accuracy of LFI was assessed in periodic intervals of three days in relation to the onset of symptoms. The optimal cut-off point was defined as the number of days required to achieve the best sensitivity and specificity. This cut-off point was also used to compare LFI accuracy according to participants' status: outpatient or hospitalized. In total, 959 patients were included, 379 (39.52%) tested positive for SARS-CoV-2 with RT-PCR, and 272 (28.36%) tested positive with LFI. LFI best performance was achieved after 10 days of the onset of symptoms, with sensitivity and specificity of 84.9% (95%CI: 79.8-89.1) and 94.4% (95%CI: 91.0-96.8), respectively. Although the specificity was similar (94.6% vs. 88.9%, p = 0.051), the sensitivity was higher in hospitalized patients than in outpatients (91.7% vs. 82.1%, p = 0.032) after 10 days of the onset of symptoms. Best sensitivity of point-of-care LFI was found 10 days after the onset of symptoms which may limit its use in acute care. Specificity remained high regardless of the number of days since the onset of symptoms.

RESUMO

OBJECTIVE: to evaluate the accuracy of an antibody point-of-care lateral flow immunoassay (LFI - Wondfo Biotech Co., Guangzhou, China) in a pediatric population. METHODS: children and adolescents (2 months to 18 years) with signs and symptoms suggestive of acute SARS-CoV-2 infection were prospectively investigated with nasopharyngeal RT-PCR and LFI at the emergency room. RT-PCR was performed at baseline, and LFI at the same time or scheduled for those with less than 7 days of the clinical picture. Overall accuracy, sensitivity and specificity were assessed, as well as according to the onset of symptoms (7-13 or ≥14 days) at the time of the LFI test. RESULTS: In 175 children included, RT-PCR and LFI were positive in 51 (29.14%) and 36 (20.57%), respectively. The overall sensitivity, specificity, positive and negative predictive value was 70.6% (95%CI 56.2-82.5), 96.8% (95%CI 91.9-99.1), 90.0% (95%CI 77.2-96.0), and 88.9% (95%CI 83.9-92.5), respectively. At 7-13 and ≥14 days after the onset of symptoms, sensitivity was 60.0% (95%CI 26.2-87.8) and 73.2% (95%CI 57.1-85.8) and specificity was 97.9% (95%CI 88.7-99.9) and 96.1% (95%CI 89.0-99.2), respectively. CONCLUSION: Despite its high specificity, in the present study the sensitivity of LFI in children was lower (around 70%) than most reports in adults. Although a positive result is informative, a negative LFI test cannot rule out COVID-19 in children.

RESUMO

BACKGROUND: Respiratory syncytial virus (RSV) and influenza are prevalent seasonal community viruses. Although not completely understood, SARS-CoV-2 may have the same means of transmission. Preventive social measures aimed at preventing SARS-CoV-2 spread could impact transmission of other respiratory viruses as well. The aim of this study is to report the detection of RSV and influenza during the period of social distancing due to COVID-19 pandemic in a heavily affected community. METHODS: Prospective study with pediatric and adult populations seeking care for COVID-19-like symptoms during the fall and winter of 2020 at two hospitals in Southern Brazil. RT-PCR tests for SARS-CoV-2, influenza A (Flu A), influenza B (Flu B) and respiratory syncytial virus (RSV) was performed for all participants. RESULTS: 1435 suspected COVID-19 participants (1137 adults, and 298 children). were included between May and August. Median age was 37.7 years (IQR = 29.6-47.7), and 4.92 years (IQR = 1.96-9.53), for the adult and child cohorts, respectively. SARS-CoV-2 was positive in 469 (32.7%) while influenza and RSV were not detected at all. CONCLUSIONS: Measures to reduce SARS-CoV-2 transmission likely exerted a huge impact in the spread of alternate respiratory pathogens. These findings contribute to the knowledge about the dynamics of virus spread. Further, it may be considered for guiding therapeutic choices for these other viruses.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: Lumbar disorders, which contribute to significant workplace absenteeism and chronic disability, are associated with a considerable financial and social burden. Although a conservative approach provides satisfactory pain relief, biomechanical improvement and is associated with a low risk of adverse effects, there is lack of consensus in the literature regarding the best therapeutic strategy in such cases. METHODS: This retrospective longitudinal study used secondary data from the institutional medical records of patients who completed a multidisciplinary program for the treatment of low back pain between 2019 and 2021. Data regarding pain levels and motor skills were obtained from patients who completed the care program at a private hospital in Bento Gonçalves, RS. The following step-wise treatment algorithm was used: evaluation by a specialist physician for the etiological diagnosis of pain, pharmacological management and dry needling, followed by standard rehabilitation intervention performed by the physiotherapy team and exercises by the physical education team. The visual analogue scale (VAS) was used to measure pain at the start and at the completion of the intervention, and the Oswestry Disability Index (ODI) was used to measure motor skills at the start and at 6 and 12 months following the multiprofessional intervention for rehabilitation. RESULTS: A reduction in pain and motor disability in patients who completed all stages of the treatment program was observed. Pain by the VAS presented the following scores: baseline 7 [5-8] and after treatment 2 [0-4]; and the scores of the ODI were: at baseline 0.34 [0.26 - 0.40], at 6 months 0.16 [0.08 - 0.26] and after treatment 0.12 [0.04 - 0.21]. CONCLUSION: The treatment program reduced the pain and disability associated with low back pain and can serve as the basis for further studies carried out to confirm the effectiveness of this intervention.


RESUMO JUSTIFICATIVA E OBJETIVOS: As doenças lombares, que contribuem para um absenteísmo significativo no local de trabalho e para a incapacidade crônica, estão associadas a um encargo financeiro e social considerável. Embora a abordagem conservadora proporcione alívio satisfatório da dor, melhore a biomecânica e esteja associada a baixo risco de efeitos adversos, não há consenso na literatura sobre a melhor estratégia terapêutica nesses casos. MÉTODOS: Neste estudo longitudinal retrospectivo, foram utilizados dados secundários dos prontuários médicos institucionais de pacientes que completaram um programa multidisciplinar para tratamento de dor lombar entre 2019 e 2021. Dados sobre níveis de dor e habilidades motoras foram obtidos de pacientes que completaram o programa assistencial de um hospital privado de Bento Gonçalves, RS. Foi utilizado o seguinte tratamento passo a passo: avaliação por médico especialista para diagnóstico etiológico da dor, manejo farmacológico e agulhamento a seco, seguido de intervenção de reabilitação padrão realizada pela equipe de fisioterapia e exercícios pela equipe de educação física. A escala analógica visual (EAV) foi utilizada para medir a dor no início e após a conclusão da intervenção, e o Índice de Incapacidade de Oswestry (ODI) foi usado para medir as habilidades motoras no início e aos 6 e 12 meses após a intervenção multiprofissional para reabilitação. RESULTADOS: Observou-se redução na dor e na incapacidade motora em pacientes que completaram todas as etapas do programa de tratamento. A intensidade da dor medida pela EAV apresentou as seguintes pontuações: basal 7 [5-8] e após tratamento 2 [0-4]; enquanto o ODI apresentou as pontuações: basal 0,34 [0,26 - 0,40], até 6 meses 0,16 [0,08 - 0,26] e após o tratamento 0,12 [0,04 - 0,21]. CONCLUSÃO: O programa de tratamento reduziu a dor e a incapacidade associadas à dor lombar e pode servir de base para novos estudos realizados para confirmar a eficácia desta intervenção.

RESUMO

OBJECTIVE: To validate the six-item female sexual function index (FSFI-6) in middle-aged Brazilian women. METHODS: Cross-sectional observational study, involving 737 (premenopausal n = 117, perimenopausal n = 249, postmenopausal n = 371) Brazilian sexually active women, aged between 40 and 55 years, not using hormonal contraceptive methods. The Brazilian FSFI-6 was developed from the translation and cultural adaptation of the Portuguese FSFI-6 version. The participants completed a general questionnaire, the FSFI-6, and the menopause rating scale (MRS). The validation was performed by AMOS 16.0 software (SPSS, Inc., Chicago, IL, USA) for a confirmatory factor analysis (CFA). The chi-square of degrees of freedom (χ2/df), the comparative fit index (CFI), the Tucker-Lewis index (TLI) and the root-mean-square error of approximation (RMSEA) were used as indices of goodness of fit. Cronbach α coefficient was used for internal consistency. RESULTS: The process of cultural adaptation has not altered the Brazilian FSFI-6, as compared with the original content. The CFA for the FSFI-6 score showed an acceptable fit (χ2/df = 3.434, CFI = 0.990, TLI = 0.980, RMSEA = 0.058, 90% confidence interval (90%CI) = 0.033-0.083, p ≤ 0.001) and a good reliability was established in FSFI-6 and MRS (Cronbach α = 0.840 and = 0.854, respectively). In addition, 53.5% of the sample had low sexual function. CONCLUSION: The FSFI-6 was translated and adapted to the Brazilian culture and is a consistent and reliable tool for female sexual dysfunction screening in Brazilian middle-aged women.


OBJETIVO: Validar o Índice de Função Sexual Feminina - 6 itens (FSFI-6, na sigla em inglês) para mulheres brasileiras de meia-idade. MéTODOS: Estudo transversal observacional que incluiu 737 (pré-menopausa n = 117, perimenopausa n = 249, pós-menopausa n = 371) mulheres brasileiras sexualmente ativas, entre 40 e 55 anos, sem métodos contraceptivos hormonais. A versão brasileira do FSFI-6 foi desenvolvida através da tradução e adaptação cultural da versão portuguesa do questionário. As participantes preencheram um questionário com dados gerais, o FSFI-6 e a escala de avaliação da menopausa (menopause rating scale [MRS]). A validação do instrumento se deu através de análise fatorial confirmatória (CFA, na sigla em inglês), realizada pelo software AMOS 16.0 (SPSS, Inc., Chicago, IL, EUA). Qui-quadrado sobre graus de liberdade (χ2/df), índice de ajuste comparativo (CFI, na sigla em inglês), índice de Tucker-Lewis (TLI) e raiz média dos quadrados dos erros de aproximação (RMSEA, na sigla em inglês) foram utilizados como índices de adequação de ajustes. O coeficiente alfa de Cronbach foi utilizado para avaliar a consistência interna. RESULTADOS: O processo de adaptação cultural não alterou a versão brasileira do FSFI-6, comparado ao conteúdo original. O CFA para o escore do FSFI-6 demonstrou ajuste aceitável (χ2/df = 3,434; CFI = 0,990; TLI = 0,980; RMSEA = 0,058; 90% IC = 0,033 a 0,083; p ≤ 0,001). Demonstrou-se boa confiabilidade entre FSFI-6 e MRS (alfa de Cronbach = 0,840 e = 0,854, respectivamente). Do total, 53,5% da amostra apresentou baixa função sexual. CONCLUSãO: O FSFI-6 foi traduzido e adaptado culturalmente, e é uma ferramenta consistente e confiável no rastreamento de disfunções sexuais em mulheres brasileiras de meia-idade.

RESUMO

OBJECTIVE: Different intrauterine environments may influence the maternal prepregnancy body weight (BW) variation up to 6 months postpartum. The objective of the present study was to verify the association of sociodemographic, obstetric, nutritional, and behavioral factors with weight variation in women divided into four groups: hypertensive (HM), diabetic (DM), smokers (SM), and control mothers (CM). METHODS: It was a convenience sample of 124 postpartum women recruited from 3 public hospitals in the city of Porto Alegre, state of Rio Grande do Sul, Brazil, between 2011 and 2016. Multiple linear regressions and generalized estimating equations (GEE) were conducted to identify the factors associated with maternal weight variation. For all GEE, the maternal weight measurements were adjusted for maternal height, parity, educational level, and the type of delivery, and 3 weight measurements (prepregnancy, preceding delivery, and 15 days postpartum) were fixed. RESULTS: A hierarchical model closely associated the maternal diagnosis of hypertension and a prepregnancy body mass index (BMI) classified as overweight with maternal weight gain measured up to the 6th month postpartum (the difference between the maternal weight at 6 months postpartum and the prepregnancy weight). These results showed that the BW of the HM group and of overweight women increased ∼ 5.2 kg 6 months postpartum, compared with the other groups. Additionally, women classified as overweight had a greater BW variation of 3.150 kg. CONCLUSION: This evidence supports the need for specific nutritional guidelines for gestational hypertensive disorders, as well as great public attention for overweight women in the fertile age.


OBJETIVO: Diferentes ambientes intrauterinos podem influenciar a variação de peso corporal pré-gestacional materno até 6 meses pós-parto. O objetivo do presente estudo foi verificar a associação de fatores sociodemográficos, obstétricos, nutricionais e comportamentais com a variação de peso em mulheres divididas em quatro grupos: hipertensas (HM), diabéticas (DM), tabagistas (SM) e controles (CM). MéTODOS: Amostra de conveniência de 124 puérperas recrutadas em 3 hospitais públicos da cidade de Porto Alegre, Rio Grande do Sul, Brasil, entre 2011 e 2016. Regressões lineares múltiplas e modelos de equações de estimativas generalizadas (GEE) foram realizados para identificar os fatores associados à variação do peso materno. Para todas as GEE, as medidas de peso materno foram ajustadas para a estatura materna, paridade, escolaridade e tipo de parto, e três medidas de peso (pré-gravidez, anterior ao parto e 15 dias pós-parto) foram fixadas. RESULTADOS: Um modelo hierárquico associou o diagnóstico materno de hipertensão e o índice de massa corporal (IMC) pré-gestacional de sobrepeso com ganho de peso materno medido até o 6° mês pós-parto (diferença entre o peso materno aos 6 meses pós-parto e o peso pré-gestacional). Estes resultados mostraram que o grupo HM e mulheres com sobrepeso aumentaram o peso corporal em ∼ 5,2 kg 6 meses pós-parto, em comparação com os demais grupos. Além disso, as mulheres classificadas com sobrepeso tiveram uma variação maior de peso corporal, de 3,150 kg. CONCLUSãO: Evidenciou-se a necessidade de diretrizes nutricionais específicas para distúrbios hipertensivos gestacionais, bem como de maior atenção dos serviços de saúde públicos para mulheres com excesso de peso em idade fértil.

RESUMO

Abstract Objective: To validate the 10-item Cervantes Scale (CS-10) among Brazilian women. Methods: This is a cross-sectional observational study involving women in the community aged 40-55 years in the Southern region of Brazil. They completed a general health, habits and socio-demographic questionnaire, the CS-10 and the Women's Health Questionnaire (WHQ). Women unable to understand the survey, not consenting to participate, or having incapacity imposing difficulties during the completion of the questionnaire were excluded. A Confirmatory Factor Analysis (CFA) was conducted with the AMOS 16.0 software. Chi-square of degrees of freedom (χ2/df), the Comparative Fit Index (CFI), the Tucker-Lewis Index (TLI) and the Root-Mean-Square Error of Approximation (RMSEA) were used as indices of goodness of fit. Cronbach's alpha coefficient was used for internal consistency. Results: A total of 422 women were included (premenopausal n=35, perimenopausal n=172, postmenopausal n=215). The CFA for the CS-10 showed a good fit (χ²/df=1.454, CFI=0.989; TLI=0.985; RMSEA=0.033; CI 90%=0.002-0.052; PCLOSE=0.921; Model p=0.049). Good reliability was established in CS-10 and WHQ (Cronbach's alpha=0.724). Postmenopausal women had higher total CS-10 scores (p≤0.0001), reflecting worse quality of life (QoL) related to menopause symptoms and confirming the greater symptomatology evaluated by high total scores for WHQ found in this population when compared to those in the premenopausal period (p=0.041). Conclusion: The CS-10 is a consistent tool for health-related QoL in Brazilian mid-aged women.
