Low and High-Normal FMR1 Triplet Cytosine, Guanine Guanine Repeats Affect Ovarian Reserve and Fertility in Women Who Underwent In Vitro Fertilization Treatment? Results from a Cross-Sectional Study.

Dynamic mutations in the 5' untranslated region of FMR1 are associated with infertility. Premutation alleles interfere with prenatal development and increase infertility risks. The number of CGG repeats that causes the highest decrease in ovarian reserves remains unclear. We evaluated the effect of FMR1 CGG repeat lengths on ovarian reserves and in vitro fertilization (IVF) treatment outcomes in 272 women with alleles within the normal range. FMR1 CGG repeat length was investigated via PCR and capillary electrophoresis. Alleles were classified as low-normal, normal, and high-normal. Serum levels of follicle-stimulating hormone and anti-Mullerian hormone (AMH) in the follicular phase of the menstrual cycle were measured, and antral follicles (AFC) were counted. IVF outcomes were collected from medical records. Regarding FMR1 CGG repeat length alleles, 63.2% of women presented at least one low-normal allele. Those carrying low-normal alleles had significantly lower AMH levels than women carrying normal or high-normal alleles. Low-normal/low-normal genotype was the most frequent, followed by low-normal/normal and normal/normal. A comparison of ovarian reserve markers and reproductive outcomes of the three most frequent genotypes revealed that AFC in the low-normal/normal genotype was significantly lower than the low-normal/low-normal genotype. The low number of FMR1 CGG repeats affected AMH levels and AFC but not IVF outcomes per cycle of treatment.

Implication of FSHB rs10835638 variant in endometriosis in Brazilian women.

OBJECTIVE: The follicle-stimulating hormone subunit beta gene rs10835638 variant (c.-211G>T) may have detrimental effects on fertility and protective effects against endometriosis. A case-control analysis was performed, aiming to investigate the possible relationship between this variant and the development and/or progression of endometriosis. METHODS: This study included 326 women with endometriosis and 482 controls without endometriosis, both confirmed by inspection of the pelvic cavity during surgery. Genotyping was performed using a TaqMan real-time polymerase chain reaction assay. Genotype and allele frequencies and genetic models were compared between the groups. RESULTS: The genotype and allele frequencies of the rs10835638 variant did not differ between women with and those without endometriosis. Subdividing the endometriosis group into fertile and infertile groups did not result in a significant difference in these frequencies. However, the subgroup with minimal/mild endometriosis had a higher frequency of the GT genotype than the Control Group, regardless of fertility. The T allele was significantly more common in women with minimal/mild endometriosis than in the Control Group in the recessive model. CONCLUSION: The T allele is associated with the development of minimal/mild endometriosis in Brazilian women.

Spatial Analysis of Notified Zika Virus Congenital Syndrome, Maranhão, 2015 to 2018. / Análise espacial da taxa de detecção de casos suspeitos de síndrome congênita pelo vírus Zika, Maranhão, 2015 a 2018.

OBJECTIVE: To identify spatial patterns in cases of changes in growth and development related to Zika virus infection and other infectious etiologies (denominated Zika virus congenital syndrome in this study) reported in Maranhão from 2015 to 2018 and their relation with socioeconomic and demographic variables. METHODS: Ecological study of notified Zika virus congenital syndrome cases in the 217 cities of Maranhão, Brasil. Spatial autocorrelation was calculated using GeoDa 1.14 software and the local and global (I) Moran's index in univariate and bivariate analyses on Zika virus congenital syndrome incidence rate with Municipal Human Development Index (MHDI), population density, Gini coefficient and the cities' time of administrative political emancipation. Local Moran's Index was calculated to identify clusters with significant spatial autocorrelation. RESULTS: Spatial autocorrelation was checked in univariate analysis of the incidence rate of Zika virus congenital syndrome (I=0,494; p=0,001) and positive correlation in bivariate analysis of the incidence rate with Municipal Human Development Index (I=0,252; p=0,001), population density (I=0,338; p=0,001) and the cities' time of administrative political emancipation (I=0,134; p=0,001). The correlation between incidence rate with Gini coefficient was not significant (I= -0,033; p=0,131). Five high-incidence clusters were found in distinct areas of the state. CONCLUSIONS: Cities with higher MHDI, higher population density and more years of administrative political emancipation had more cases of Zika virus congenital syndrome notified.

OBJETIVO: Identificar padrões espaciais em casos de lactentes com alterações de crescimento e desenvolvimento relacionadas à infecção pelo vírus Zika e outras etiologias infecciosas (neste trabalho denominado de síndrome congênita pelo vírus Zika), notificados no Maranhão de 2015 a 2018 e sua relação com variáveis socioeconômicas e demográficas. MÉTODOS: Estudo ecológico de casos suspeitos notificados de síndrome congênita pelo vírus Zika nos 217 municípios do Maranhão, Brasil. Calculou-se a autocorrelação espacial pelos índices de Moran local e global (I) univariado e bivariado da taxa de detecção de casos suspeitos de síndrome congênita pelo vírus Zika com índice de desenvolvimento humano municipal, densidade demográfica, índice de Gini e tempo de emancipação político-administrativa dos municípios. O índice de Moran local foi calculado para localizar clusters com autocorrelação espacial significativa. RESULTADOS: Houve autocorrelação espacial na análise univariada da taxa municipal de detecção de casos suspeitos de síndrome congênita pelo vírus Zika (I=0,494; p=0,001) e, na análise bivariada, correlação positiva da taxa de detecção de casos suspeitos com índice de desenvolvimento humano municipal (I=0,252; p=0,001), densidade demográfica (I=0,338; p=0,001) e tempo de emancipação dos municípios (I=0,134; p=0,001). Não houve correlação significativa da taxa de detecção de casos suspeitos com o índice de Gini (I= -0,033; p=0,131). Cinco clusters de alta detecção de casos suspeitos foram encontrados em áreas distintas do estado. CONCLUSÕES: Os municípios com maior índice de desenvolvimento humano municipal, maior densidade demográfica e mais tempo de emancipação político-administrativa tiveram mais casos suspeitos notificados de síndrome congênita pelo vírus Zika.

Effects of FSHR and FSHB Variants on Hormonal Profile and Reproductive Outcomes of Infertile Women With Endometriosis.

Background: Single nucleotide variants (SNVs) FSHB:c.-211G>T, FSHR:c.919G>A, and FSHR:c.2039G>A were reported to be associated with the variability in FSH and LH levels, and in vitro fertilization (IVF) outcomes. In this study, we aimed to evaluate the effects of FSHB:c.-211G>T, FSHR:c.919G>A, and FSHR:c.2039G>A variants, alone and combined, on the hormonal profile and reproduction outcomes of women with endometriosis. Methods: A cross-sectional study was performed comprising 213 infertile Brazilian women with endometriosis who underwent IVF treatment. Genotyping was performed using TaqMan real-time PCR. Variables were compared according to the genotypes of each variant and genetic models, and the combined effects of the SNVs were evaluated using the multifactorial dimensionality reduction method. Results: FSHB:c.-211G>T affected LH levels in women with overall endometriosis and minimal/mild disease. FSHR:c.919G>A affected FSH levels in women with overall endometriosis and the number of oocytes retrieved in those with moderate/severe endometriosis. Moreover, the FSHR:c.2039G>A affected FSH levels in women with overall endometriosis, LH levels and total amount of rFSH in those with minimal/mild disease, and number of follicles and number of oocytes retrieved in those with moderate/severe endometriosis. No effect on hormone profile or reproductive outcomes was observed when the genotypes were combined. Conclusions: Variants of the FSHB and FSHR genes separately interfered with the hormonal profiles and IVF outcomes of women with endometriosis.

Analysis of current SARS-CoV-2 infection in a large population of blood donors evidenced that RNAemia is rare in plasma.

BACKGROUND: Transmission of SARS-CoV-2 by asymptomatic individuals and by blood transfusion are important issues to understand to control the viral spread. In this work, we estimated the current SARS-CoV-2 infection rate in blood donors from Belo Horizonte, Brazil. STUDY DESIGN AND METHODS: Saliva and blood samples were collected from 4103 blood donors from June 15 to September 30, 2020. Saliva samples were tested by real-time RT-PCR for SARS-CoV-2 in mini-pools of four samples. Individual samples were tested for positive or inconclusive pools, and positive donors had their plasma tested. RESULTS: Twenty-seven (0.66%) blood donors were positive for SARS-CoV-2 in their saliva, but their plasma was negative, except for one, who presented a high viral load in saliva and nasopharyngeal samples and RNAemia in the plasma close to the limit of detection. Fourteen (56%) positive blood donors reported mild symptoms related to COVID-19 after donation, but the viral load levels were not statistically different between symptomatic and asymptomatic individuals. DISCUSSION: Despite the measures taken by Blood Centers to avoid blood donors with SARS-CoV-2 infection, asymptomatic or presymptomatic carriers are able to donate. The risk of the virus transmission by transfusion seems to be negligible since plasma RNAemia was seen at a very low level in only one (3.7%) of the positive donors, but other studies must be performed to confirm this finding.

Physical activity in pregnancy and adverse birth outcomes.

This study focused on the association between physical activity in the second trimester of pregnancy and adverse perinatal outcomes: low birth weight (LBW), preterm birth (PTB), and intrauterine growth restriction (IUGR). The study used a sample from the BRISA cohort, São Luís, Maranhão State, Brazil, which included women with singleton pregnancy, gestational age from 22 to 25 weeks confirmed by obstetric ultrasound performed at < 20 weeks, and re-interviewed in the first 24 hours postpartum (n = 1,380). Level of physical activity was measured by the International Physical Activity Questionnaire (IPAQ), short version, categorized as high, moderate, and low. A directed acyclic graph (DAG) was used to identify minimum adjustment to control confounding. High physical activity was not associated with LBW (RR = 0.94; 95%CI: 0.54-1.63), PTB (RR = 0.86; 95%CI: 0.48-1.54), or IUGR (RR = 0.80; 95%CI: 0.55-1.15). The results support the hypothesis that physical activity during pregnancy does not result in adverse perinatal outcomes.

Investigou-se a associação entre atividade física durante o segundo trimestre gestacional e os desfechos perinatais adversos: baixo peso ao nascer (BPN), nascimento pré-termo (NPT) e restrição de crescimento intrauterino (RCIU). Foi utilizada amostra da coorte BRISA, São Luís, Maranhão, Brasil, que incluiu mulheres com gravidez única, idade gestacional de 22 a 25 semanas confirmada por ultrassonografia obstétrica realizada com < 20 semanas, reentrevistadas nas primeiras 24 horas após o parto (n = 1.380). O nível de atividade física foi medido pelo Questionário Internacional de Atividade Física (IPAQ), versão curta, e categorizado em alto, moderado e baixo. Gráfico acíclico direcionado (DAG) foi utilizado para identificar ajuste mínimo para o controle de confundimento. Nível alto de atividade física não foi associado ao BPN (RR = 0.94; IC95%: 0,54-1,63), NPT (RR = 0,86; IC95%: 0,48-1,54) ou RCIU (RR = 0,80; IC95%: 0,55-1,15). Os resultados fortalecem a hipótese de que a prática de atividade física na gestação não parece resultar em desfechos adversos ao nascimento.

Changes in perinatal health in two birth cohorts (1997/1998 and 2010) in São Luís, Maranhão State, Brazil.

The objective of this study was to analyze changes in perinatal health in two birth cohorts started in 1997/1998 and 2010, respectively, in São Luís, Maranhão State, Brazil. A total of 2,493 live born infants were included in 1997/1998 and 5,166 in 2010. Low birth weight (LBW) rate did not change (8.5% in 1997/1998 and 8.6% in 2010). Preterm birth (PTB) rate also remained stable (13.2% in 1997/1998 and 13% in 2010). Teenage deliveries and births to single mothers decreased. Maternal schooling and prenatal care coverage increased. Intrauterine growth restriction (IUGR) decreased from 13.3% to 10.6% (p < 0.001). The perinatal mortality rate decreased from 36.6 to 20.7 per 1,000 (p < 0.001) and the infant mortality rate (IMR) dropped from 28.5 to 12.8 per 1,000 (p < 0.001). The cesarean rate increased from 34.1% to 47.5% (p < 0.001). In conclusion, despite favorable changes in socio-demographic, behavioral, and health service factors and decreasing rates of IUGR and perinatal and infant mortality, LBW and PTB remained stable, while the cesarean rate increased.

High-grade cervical lesions among women attending a reference clinic in Brazil: associated factors and comparison among screening methods.

BACKGROUND: Although screening for cervical cancer is recommended for women in most countries, the incidence of cervical cancer is greater in developing countries. Our goal was to determine the prevalence and factors associated with high-grade lesions/cervical cancer among women attending a reference clinic in Brazil and evaluate the correlation of histology with cytology, colposcopy and the high-risk HPV (HR-HPV) tests. METHODS: A cross-sectional study of women attending a colposcopy clinic was carried out. The patients were interviewed to collect demographic, epidemiological and clinical data. Specimens were collected for cervical cytology, Chlamydia trachomatis and HPV testing using the Hybrid Capture (HC) and PCR tests. Colposcopy was performed for all patients and biopsy for histology when cell abnormalities or cervical intraepithelial neoplasia (CIN) were present. RESULTS: A total of 291 women participated in the study. The median age was 38 years (DIQ: 30-48 years). The prevalence of histologically confirmed high-grade lesions/cervical cancer was 18.2% (95%, CI: 13.8%-22.6%), with 48 (16.5%) cases of CIN-2/CIN-3 and 5 (1.7%) cases of invasive carcinoma. In the final logistic regression model, for ages between 30 and 49 years old [OR = 4.4 (95%: 1.01-19.04), history of smoking [OR = 2.4 (95%, CI: 1.14-5.18)], practice of anal intercourse [OR = 2.4 (95%, CI: 1.10-5.03)] and having positive HC test for HR-HPV [OR = 11.23 (95%, CI: 4 0.79-26, 36)] remained independently associated with high-grade lesions/cervical cancer. A total of 64.7% of the cases CIN-3\Ca in situ were related to HPV-16. Non-oncogenic HPV were only found in CIN-1 biopsy results. Compared to histology, the sensitivity of cytology was 31.8%, the specificity 95.5%; the sensitivity of colposcopy for high-grade lesions/cervical cancer was 51.0%, specificity was 91.4% and the concordance with HPV testing was high. CONCLUSIONS: The results confirm an association of HR-HPV with precursor lesions for cervical cancer. These data emphasize that cytological screening to detect precursor lesions is still important in some regions and that HR-HPV should be included for screening.

Análise clínica e epidemiológica de 348 casos de adenocarcinoma prostático atendidos em um centro oncológico de referência no Maranhão, Brasil / Análisis Clínico y Epidemiológico de 348 Casos de Adenocarcinoma de PróstataTratados en un Centro de Referencia Oncológico en Maranhão, Brasil / Clinical and Epidemiological Analysis of 348 Cases of Prostate Adenocarcinoma Attended in a Cancer Care Center in Maranhão, Brazil

Introdução: O câncer de próstata é a principal neoplasia maligna no sexo masculino, depois do câncer de pele nãomelanoma. Informações clínicas e epidemiológicas sobre essa patologia no Maranhão são escassas. Objetivos: Analisar informações clínicas e epidemiológicas de pacientes diagnosticados com câncer de próstata em um centro oncológico de referência no Maranhão, no período de janeiro de 2008 a dezembro de 2009. Método: Trata-se de um estudo retrospectivo e descritivo onde foram pesquisados 348 prontuários de pacientes com diagnóstico de câncer de próstatano Instituto Maranhense de Oncologia Aldenora Bello. As variáveis pesquisadas foram: faixa etária; procedência; ocupação; antígeno prostático específico inicial; escore de Gleason da biópsia; escore de Gleason da peça cirúrgica (em pacientes cujas terapêuticas incluíram prostatectomia radical ou ressecção transuretral de próstata); e tratamento instituído. Resultados: A faixa etária mais acometida foi de 71 a 80 anos (39,7%). A maior parte dos pacientes era procedente de São Luís - MA (64,1%) e não possuía ocupação (55,2%). A maioria dos pacientes (32,8%) apresentou antígeno prostático específico inicial entre 4,1 e 10 ng/ml. O Gleason da biópsia revelou, em 48,5% dos casos, tumores moderados a fracamente diferenciados. A terapêutica predominante foi composta de tratamento clínico e/ou orquiectomia subcapsular bilateral. Conclusão: O presente estudo demonstrou uma associação significativa do antígeno prostático específico com a faixa etária e o Gleason, revelando maior tendência de aumento dos seus níveis quanto maior a idade e maior a graduação histológica dos tumores. Do total dos pacientes, 36,5% obtiveram escoresde Gleason da biópsia e peça cirúrgica equivalentes

Confidential donation confirmation as an alternative to confidential unit exclusion: 15 months experience of the HEMOMINAS foundation.

BACKGROUND: Confidential unit exclusion remains a controversial strategy to reduce the residual risk of transfusion-transmitted infections. OBJECTIVE: This study aimed to analyze confidential unit exclusion from its development in a large institution in light of confidential donation confirmation. METHODS: Data of individuals who donated from October 1, 2008 to December 31, 2009 were analyzed in a case-control study. The serological results and sociodemographic characteristics of donors who did not confirm their donations were compared to those who did. Variables with p-values < 0.20 in univariate analysis were included in a logistic multivariate analysis. RESULTS: In the univariate analysis there was a statically significant association between positive serological results and response to confidential donation confirmation of "No". Donation type, (firsttime or return donor - OR 1.69, CI 1.37-2.09), gender (OR 1.66, CI 1.35-2.04), education level (OR 2.82, CI 2.30-3.47) and ethnic background (OR 0.67, CI 0.55-0.82) were included in the final logistic regression model. In all logistic regression models analyzed, the serological suitability and confidential donation confirmation were not found to be statistically associated. The adoption of new measures of clinical classification such as audiovisual touch-screen computer-assisted self-administered interviews might be more effective than confidential unit exclusion in the identification of donor risk behavior. The requirement that transfusion services continue to use confidential unit exclusion needs to be debated in countries where more specific and sensitive clinical and serological screening methods are available. CONCLUSION: Our findings suggest that there are not enough benefits to justify continued use of confidential donation confirmation in the analyzed institution.

The serological results and sociodemographic characteristics of donors who did not confirm their donations were compared to those who did. Variables with p-values < 0.20 in univariate analysis were included in a logistic multivariate analysis. RESULTS: In the univariate analysis there was a statically significant association between positive serological results and response to confidential donation confirmation of "No". Donation type, (firsttime or return donor - OR 1.69, CI 1.37-2.09), gender (OR 1.66, CI 1.35-2.04), education level (OR 2.82, CI 2.30-3.47) and ethnic background (OR 0.67, CI 0.55-0.82) were included in the final logistic regression model. In all logistic regression models analyzed, the serological suitability and confidential donation confirmation were not found to be statistically associated. The adoption of new measures of clinical classification such as audiovisual touch-screen computer-assisted self-administered interviews might be more effective than confidential unit exclusion in the identification of donor risk behavior. The requirement that transfusion services continue to use confidential unit exclusion needs to be debated in countries where more specific and sensitive clinical and serological screening methods are available. CONCLUSION: Our findings suggest that there are not enough benefits to justify continued use of confidential donation confirmation in the analyzed institution.

Blood donor deferral in Minas Gerais State, Brazil: blood centers as sentinels of urban population health.

BACKGROUND: Shortage of safe blood donors is frequent and it is important to understand the causes of deferral of potential donors, who reside mainly in urban areas, to improve recruitment campaigns aiming at the quality/availability of donors. STUDY DESIGN AND METHODS: In Minas Gerais State, Brazil, Hemominas Foundation collects, analyzes, and distributes more than 90 percent of blood. Blood is collected in 19 centers in cities. In 2006, data from 335,109 attempts to donate were analyzed. RESULTS: Seventy-seven percent of donor candidates were less than 40 years old, with 57.1 percent nonwhite and 66 percent male. A total of 21.6 percent were deferred at the interview. Women were more clinically deferred than men (25.5% vs. 19.6%). In larger cities, the proportion of first-time donors (FTs) was higher (67.8%). The main causes of permanent deferral among FTs were neurologic diseases (37.5%), chronic hypertension (22.2%), and endocrinologic diseases (9.9%). The main causes of temporary clinical deferral in this group were risky behavior for sexually transmitted diseases (32.6%), anemia (8.5%), and hypertension (6%). The main causes of permanent deferral in repeat donors (RTs) were chronic hypertension (31.6%) and neurologic diseases (22.1%); for temporary deferral it was anemia (22.6%). A total of 2.9% of the collected blood bags were discarded due to reactive tests (FTs = 34.82/1000; RTs = 3.51/1000). CONCLUSION: A deferral study in blood donor candidates may shed light on regional diversity, highlighting how social inequalities and health status of the general population may affect the blood supply. Risk factors and marker rates derived from the donor pool may be useful to gain insights regarding public health issues.

[Systemic bone mineral density versus clinical periodontal condition: cross-sectional study in postmenopausal women]. / Densidade mineral óssea sistêmica vs situação clínica periodontal: estudo transversal em mulheres na pós-menopausa.

OBJECTIVE: To assess the systemic bone mineral density (BMD) and the periodontal situation in postmenopausal women, to understand the possible role of osteoporosis as a risk factor for periodontal disease. METHODS: The sample was comprised of 47 postmenopausal women, divided into 3 groups: 14 patients with normal bones (G1), 17 with osteopenia (G2) and 16 patients with osteoporosis (G3). Data was obtained using bone mineral density (BMD), obtained by dual energy x-ray absorptiometry (DXA) in the lumbar area (L1-L4). Periodontal condition was evaluated by Gingival Index (GI), Plaque Index (PI) and Clinical Attachment Level (CAL). Results were analyzed and submitted to statistical treatment, through the One Way ANOVA: (alpha=0.05) test and the Pearson's Correlation test (alpha=0.01). RESULTS: GI, PI and CAL variables did not disclose a significant difference in the periodontal situation of postmenopausal women A significant correlation between periodontal parameters GI, PI and CAL (p<0,001) was observed, however no significant correlation was detected between periodontal parameters (GI, PI and CAL) and systemic bone condition of postmenopausal women, evaluated by BMD (p>0.01). CONCLUSION: The periodontal situation of postmenopausal women does not depend on the systemic bone mass and there is no significant correlation between BMD and periodontal parameters. However, further longitudinal surveys are required to understand osteoporosis as a risk factor of periodontal disease.

Densidade mineral óssea sistêmica vs situação clínica periodontal: estudo transversal em mulheres na pós-menopausa / Systemic bone mineral density versus clinical periodontal condition: cross-sectional study in postmenopausal women

OBJETIVO: Analisar a densidade mineral óssea sistêmica (DMO) e a situação periodontal em mulheres na pós-menopausa, visando compreender o papel da osteoporose como um fator de risco à doença periodontal. MÉTODOS: A amostra da pesquisa foi constituída por 47 mulheres na pós-menopausa, que foram divididas em três grupos: 14 com osso normal (G1), 17 no grupo com osteopenia (G2) e 16 pacientes com osteoporose (G3), através da avaliação da densidade mineral óssea (DMO), aferida pela absormetria de dupla emissão com raios-X na área lombar (L1-L4). A condição periodontal foi avaliada pelo índice gengival (IG), índice da placa (IP) e o nível de inserção clínica (NIC). Os resultados tabulados foram analisados e submetidos ao tratamento estatístico, através do teste ANOVA a um critério (α=0,05) e o teste de correlação de Pearson (α=0,01). RESULTADOS: Verificou-se não haver diferenças significativas na situação periodontal em mulheres na pós-menopausa, através das variáveis IG, IP e NIC. Observou-se correlação significativa entre os parâmetros periodontais IG, IP e NIC entre si (p<0,001), contudo não foi detectada correlação significativa entre os parâmetros periodontais (IG, IP, NIC) e a condição sistêmica do osso das mulheres na pós-menopausa, avaliada através da DMO (p>0,01). CONCLUSÃO: A situação periodontal em mulheres na pós-menopausa não depende da massa óssea sistêmica, não havendo correlação significativa entre DMO e os parâmetros periodontais, sendo necessárias pesquisas longitudinais para considerar a osteoporose como um fator de risco à doença periodontal.

Associação entre osteoporose e doença periodontal em mulheres na pós-menopausa / Association between osteoporosis and periodontal disease

OBJETIVO: o objetivo desse estudo foi verificar a associação entre a osteoporose e a doença periodontal. MÉTODOS: foram incluídas 39 mulheres na pós-menopausa, que foram divididas em três grupos conforme categorização da massa óssea, por meio da avaliação da densidade mineral óssea, aferida pela absormetria de dupla emissão com raios X na área lombar (L1-L4): osso normal, osteopenia e osteoporose. Foi aplicado o índice de nível de inserção clínica (NIC) para todas as participantes no início da pesquisa e após um ano, por apenas um examinador. Os dados da situação periodontal foram submetidos à análise estatística com o teste t de Student pareado. RESULTADOS: o exame periodontal revelou que as mulheres na pós-menopausa com osteopenia apresentaram menor média do NIC no exame clínico periodontal inicial (2,1±1,1 mm), enquanto as pertencentes ao grupo osso normal mostraram menor perda dos tecidos de sustentação dos dentes após um ano (3,1±1,6 mm). Após a realização do tratamento estatístico, observou-se que não houve diferença significativa para a situação periodontal no osso normal, entretanto foi constatada diferença estatística nas pacientes do osteopenia e osteoporose, quando comparados os valores do NIC, nos dois períodos de avaliação. CONCLUSÕES: conclui-se que a osteoporose na pós-menopausa pode ser considerada como possível fator de risco para a doença periodontal.

PURPOSE: to verify the association of osteoporosis with periodontal disease. METHODS: the study has included 39 postmenopausal women divided in three groups according to bone mass categories, through evaluation of mineral bone density (MBD), measured by X-ray double emission absorbimetry in the lumbar area (L1-L4): ): normal bone; osteopenia and osteoporosis. In all the participants the Clinical Insertion Level (CIL) index has been determined at the research onset and after one year, by the same examiner. The periodontal situation data have been submitted to statistical analysis with the paired t-Student test. RESULTS: the periodontal exam has shown that postmenopausal women in the osteopenia presented lower CIL at the initial periodontal clinical exam (2.1±1.1 mm), while the ones in the normal bone showed less teeth support tissue loss after one year (3.1±1.6 mm). The statistical analysis has shown that there was no significant difference for the periodontal situation in the normal bone, but there was significant statistical difference for the osteopenia and osteoporosis patients, when CIL values from both evaluation periods were compared. CONCLUSIONS: it is concluded that postmenopausal osteoporosis may be a possible risk factor for periodontal disease.
