RESUMO

Introduction Women require effective contraception until they reach menopause. The long acting reversible contraceptives (LARC) and the depot-medroxyprogesterone acetate (DMPA, Depo-Provera®, Pfizer, Puurs, Belgium) are great options and can replace possible sterilizations. Purpose To assess the relationship between the use of LARCs and DMPA and terminations ascribed to menopause and sterilizations in a Brazilian clinic. Methods We reviewed the records of women between 12 and 50 years of age attending the clinic that chose to use a LARC method or DMPA. Cumulative termination rates due to sterilization or because the woman had reached menopause were computed using single decrement life-table analysis over 32 years. We also examined all records of surgical sterilization at our hospital between the years 1980-2012. Results Three hundred thirty-two women had continuously used the same contraceptive until menopause, and 555 women had discontinued the method because they or their partners underwent sterilization. From year 20 to year 30 of use, levonorgestrel intrauterine-releasing system (LNG-IUS - Mirena®, Bayer Oy, Turku, Finland; available since 1980), copper intrauterine device (IUD - available since 1980) and DMPA users showed a trend of cumulative higher discontinuation rates due to menopause when compared with the discontinuation rates due to sterilization. Over the study period, a steep decline in the use of sterilization occurred. Conclusion Over the past 15 years of research we have observed a trend: women usually preferred to continue using LARC methods or DMPA until menopause rather than decide for sterilization, be it their own, or their partners'. The annual number of sterilizations dropped in the same period. The use of LARC methods and DMPA until menopause is an important option to avoid sterilization, which requires a surgical procedure with potential complications.

Resumo Introdução Mulheres necessitam de contracepção até atingirem a menopausa. Os contraceptivos reversíveis de longa duração e o acetato de medroxiprogesterona de depósito (AMPD) são ótimas opções para substituir possíveis esterilizações. Objetivo Avaliar a relação entre o uso de contraceptivos reversíveis de longa duração (LARCs) e AMPD com terminações atribuídas à menopausa e a esterilizações em uma clínica brasileira. Métodos Revisamos os registros de mulheres entre 12 e 50 anos de idade atendidas em clínica e que escolheram usar LARC ou AMPD. Índices de terminação acumulada devido à esterilização ou à menopausa foram computados usando análise de tabela de vida durante 32 anos. Também examinamos todos os registros de cirurgias de esterilização em nosso hospital no período de 1980 a 2012. Resultados Trezentas e trinta e duas mulheres usaram continuamente o mesmo contraceptivo até a menopausa, e 555 mulheres não deram continuidade ao método pelo fato de elas ou seus parceiros terem se submetido à esterilização. De 20 a 30 anos de uso, usuários de sistema intrauterino de levonorgestrel, dispositivo intrauterino de cobre e AMPD apresentaram tendência de maiores índices de descontinuidade devido à menopausa quando comparados a índices de descontinuidade devido à esterilização. No período de estudo, ocorreu um declínio acentuado no uso de esterilização. Conclusão Nos últimos 15 anos do estudo, foi observada uma tendência na qual mulheres optaram mais por continuar usando LARC ou AMPD até a menopausa do que pela esterilização própria ou de seus parceiros. O número anual de esterilizações caiu no mesmo período. O uso de LARC e AMPD até a menopausa é uma opção importante para evitar a esterilização, que exige um procedimento cirúrgico com potenciais complicações.

RESUMO

Identification of Lactobacillus sp. strains by phenotypic methods may lead to doubtful results possibly interfering in the reliability of the epidemiological and probiotics studies. Therefore this study aimed to determine the best methodology for the identification of the large diversity of lactobacilli species found in the vagina by comparing two techniques, one based on their biochemical profile and other employing molecular biology. A carbohydrate fermentation test (API 50 CH) was compared with multiplex polymerase chain reaction (PCR) for the identification of species of vaginal lactobacilli from 135 healthy women. The kappa index was used to evaluate agreement between the methods. Using the molecular technique, L. crispatus (32.6 percent), L. jensenii (25 percent) and L. gasseri (20.6 percent) were the most frequent species. However, using the biochemical technique, the most frequent species were: L. acidophilus (34.8 percent), L. crispatus (27.2 percent) and L. fermentum (13 percent). Although L. acidophilus was the most frequent specie found by biochemical tests, no strain of this microorganism was detected by PCR. Agreement between the methods was low for identification of all the most common species. Although rates of L. crispatus detected were similar using both methods (32.6 percent and 27.2 percent), agreement between them was relatively low (kappa = 0.52). Conclusions: Our results confirmed the limitation of the biochemical method and the applicability of a previously published molecular method (Multiplex PCR) for the identification of lactobacilli in the vaginal tract, focusing on further necessity of its improvement for also targeting L. vaginalis and L. iners.

RESUMO

BACKGROUND: The aim of the study was to compare the bone mineral density (BMD) of postmenopausal women who had used depot-medroxyprogesterone acetate (DMPA) or a copper intrauterine device (IUD) as a comparison group until menopause. STUDY DESIGN: BMD was measured using dual-energy X-ray absorptiometry at the nondominant forearm for up to 3 years following menopause in 135 women aged 43-58 years: 36 former DMPA users and 99 former IUD users. RESULTS: Mean duration of use was (mean+/-SEM) 9.4+/-3.8 and 14.7+/-6.2 years for the DMPA and IUD groups, respectively. One year after menopause, mean distal radius BMD was 0.435 and 0.449 in DMPA and IUD users, respectively, and 0.426 and 0.447 at 2-3 years following menopause. Ultra-distal BMD was 0.369 and 0.384 in DMPA and IUD users, respectively, at 1 year, and 0.340 and 0.383 at 2-3 years. CONCLUSIONS: At 1 and 2-3 years following menopause, no significant differences were observed in the BMD of postmenopausal women aged 43-58 years, who had used DMPA or an IUD until menopause.

RESUMO

BACKGROUND: Prostate-specific antigen (PSA) in vaginal fluid indicates exposure to semen, and was used to assess condom effectiveness, although validity and reliability have not been fully evaluated. Our objective was to compare PSA in self-collected samples with samples collected by a nurse. METHODS: We conducted two studies, each with 100 women aged 18-48 years. In the first, a nurse exposed each participant to her partner's semen (10, 100 and 1000 microl), and nurse and participant collected samples. In the second, each participant sampled before and after using two male condoms (MC) and two female condoms (FC); a nurse collected another sample afterwards. RESULTS: PSA concentration increased with semen exposure, but was lower in nurse-collected samples. Both procedures were sensitive, almost 100% after exposure to 100-1000 microl of semen. PSA detection rates with MC and FC were 13% and 28% in self-collected samples, 8% and 9% in nurse-collected samples. Concordance between sample types was 93% with the MC (95% CI: 89%; 96%), 78% with the FC (95% CI: 72%; 84%). PSA decay between sampling times may explain higher values in self-collected samples. CONCLUSIONS: PSA is a highly sensitive surrogate endpoint for condom effectiveness studies. Self-collected and nurse-collected samples are equivalent, but sample collection timing is critical.

RESUMO

OBJECTIVE: To evaluate factors associated to presence of free RNA-HIV in the vagina. METHODS: Cross-sectional study with HIV-infected women, excluding those who had undergone hysterectomy, had used vaginal medication within the last 48 hours, had had unprotected sex less than 72 hours before, were pregnant, or had genital bleeding. After signing an informed consent, blood samples were obtained for T CD4 lymphocytes count and plasmatic viral load, in addition to cervico-vaginal lavage using 10 mL of sterile normal saline, later centrifuged, aliquoted and stored at - 70 degrees C to quantify free HIV-RNA. Plasmatic and vaginal viral load were measured using the kit HIV Monitor v1.5 Cobas Amplicor, Roche. Hybrid Capture test Digene was utilized for HPV (high and low risk), chlamydia trachomatis and N. gonorrhoea detection from an endocervical sample. Vaginal swab for bacterioscopy by the Gram method, evaluated according to Nugent criteria was obtained. RESULTS: Among 200 women evaluated, 73.5% were using HAART. The RNA-HIV was detectable in the vaginal lavage of 18 (9%), but in only one of those who had undetectable plasma viral load (0.5%). The vaginal prevalence of HIV was 24 times higher among those with detectable plasmatic HIV. Plasma viral load > 1500 copies/mL, no HAART use, reduced CD4 and bacterial vaginosis had increased prevalence of vaginal HIV-RNA, but in the adjusted statistical analysis, only the former remained significant CONCLUSION: Prevalence of vaginal HIV-RNA was low (9%). Plasmatic viral load > 1500 copies/mL, was the only risk factor for free vaginal HIV-RNA.

RESUMO

OBJETIVO: Avaliar os fatores associados à presença de RNA-HIV na vagina. MÉTODOS: Estudo de corte transversal, em mulheres infectadas por HIV, excluindo-se aquelas com antecedente de histerectomia, as em uso de medicações vaginais nas últimas 48 horas, as que se referiram à relação sexual desprotegida há menos de 72 horas, as gestantes e aquelas com sangramento genital. Após consentimento, coletou-se amostra sanguínea para contagem de linfócitos T CD4 e carga viral plasmática de HIV, além de lavado vaginal com 10mL de solução salina, que foi centrifugado, aliquotado e armazenado em freezer -70°C para posterior quantificação de RNA-HIV livre. A mensuração de carga viral de RNA-HIV livre plasmática e vaginal foi realizada utilizando-se o kit HIV Monitor v1.5 Cobas Amplicor®, Roche. Pesquisou-se a presença de HPV de alto e baixo risco, clamídia e gonococo por Captura Híbrida II®, Digene, em amostra endocervical. Colheu-se amostra vaginal para bacterioscopia com coloração de Gram, utilizando-se os critérios de Nugent. RESULTADOS: Entre as 200 mulheres estudadas, 73,5 por cento usavam terapia anti-retroviral (TARV) com drogas múltiplas. O RNA-HIV foi detectável no lavado vaginal de 18 delas (9 por cento), mas em apenas uma daquelas que tinham carga viral plasmática indetectável (0,5 por cento). A prevalência de HIV vaginal foi 24 vezes maior naquelas em que HIV plasmático era detectável. Carga viral plasmática de HIV, não usar TARV, CD4 reduzido e vaginose bacteriana aumentaram a prevalência de RNA-HIV vaginal, mas apenas a carga viral plasmática se manteve significativa na análise ajustada. CONCLUSÃO: A prevalência de RNA-HIV vaginal foi baixa (9 por cento). A carga viral acima de 1.500 cópias/mL foi a única variável que permaneceu como fator de risco para RNA-HIV vaginal livre.
