Infertilidade, justiça reprodutiva e pandemia de COVID-19: reflexões sobre acesso e barreiras / Infertility, reproductive justice and the COVID-19 pandemic: reflections on access and barriers / Infertilidad, justicia reproductiva y la pandemia de COVID-19: reflexiones sobre acceso y barreras

Objetivo: refletir sobre o acesso a serviços de saúde para infertilidade e reprodução humana assistida durante o período da pandemia de COVID-19, na perspectiva da justiça reprodutiva. Metodologia: utilizou-se dados do inquérito online da pesquisa Pandemia de COVID-19e práticas reprodutivas de mulheres no Brasil, que obteve 8.313 respostas de mulheres residentes em todas as regiões do país, de 18 anos ou mais. O questionário autoaplicável circulou entre julho e outubro de 2021, contendo questões fechadas e abertas. A análise descritiva das respostas objetivas de 242 mulheres que referiram buscar atendimento para infertilidade contou com o cálculo de frequências simples das variáveis. Já os textos escritos nos espaços abertos do questionário foram submetidos à análise temática. Resultados: o estudo verificou a existência de barreiras institucionais e não institucionais para os cuidados da infertilidade, ambas incrementadas pela pandemia. Conclusão: recomenda-se a efetivação de política pública que garanta acesso pleno a todas as pessoas, haja vista que o tratamento para infertilidade e reprodução assistida tende a se restringir a mulheres cisgênero, de camadas médias e altas, mais escolarizadas e majoritariamente brancas.

Objective: to critically examine access to health services for infertility and assisted human reproduction during the COVID-19 pandemic, emphasizing the perspective of reproductive justice. Methods: data for analysis were derived from the online survey titled COVID-19 Pandemic and Women's Reproductive Practices in Brazil, garnering 8,313 responses from women aged 18 years or older residing in all regions of the country. The self-administered questionnaire circulated from July to October 2021 and comprised both closed and open-ended questions. Descriptive analysis of the objective responses obtained from 242 women actively seeking infertility care involved the calculation of simple frequencies for relevant variables. Responses provided in the open-ended sections of the questionnaire underwent thematic analysis. Results: revealed the presence of both institutional and non-institutional barriers to infertility care, with a notable exacerbation during the pandemic. Conclusion: given that infertility and assisted reproduction treatment predominantly cater to cisgender women from middle and upper socio-economic strata, characterized by higher education levels and mostly white, there is a compelling need for the implementation of public policies that ensure equitable access for all individuals.

Performance of Chimeric Trypanosoma cruzi Antigens in Serological Screening for Chagas Disease in Blood Banks.

Chagas disease (CD) is among the top 10 causes of inability to blood donation. Blood donation centers screen for anti-Trypanosoma cruzi antibodies using highly sensitive immunoenzymatic (ELISA) or chemiluminescent methods, which can lead to false positive results. Since positive samples cannot be used, to avoid the loss of valuable blood donations, it is necessary to improve specificity without reducing the sensitivity of the tests used for blood screening. For this purpose, our group has developed four chimeric proteins (IBMP-8.1, IBMP-8.2, IBMP-8.3, and IBMP-8.4) that have been evaluated in phase I and II studies with high performance and low cross-reactivity rates. The study included a panel of 5,014 serum samples collected from volunteer blood donors at the Hematology and Hemotherapy Foundation of the State of Bahia (Brazil). They were subjected to the detection of anti-T. cruzi antibodies, using all four IBMP antigens individually and latent class analysis (LCA) as a reference test, since there is no gold standard test for this purpose. Considering the sample size analyzed, LCA classified 4,993 (99.6%) samples as T. cruzi-negative and 21 (0.42%) as T. cruzi-positive. Sensitivity values ranged from 85.71% for IBMP-8.1 and 90.48% for IBMP-8.2-95.24% for IBMP-8.3 and 100% for IBMP-8.4, while specificity ranged from 99.98% for IBMP-8.3 and IBMP-8.4-100% for IBMP-8.1 and IBMP-8.2. Accuracy values ranged from 99.4 to 99.98%. The pretest probability for the molecules was 0.42, whereas the positive posttest probability ranged from 95.24 to 99.95% and the negative posttest probability ranged from 0.00001 to 0.0006% for all antigens. The higher odds ratio diagnosis was found for IBMP-8.4, which has been shown to be a safe single antigen for serological screening of CD in blood samples. The use of chimeric IBMP antigens is an alternative to reduce the number of bags discarded due to false-positive results. These molecules have high diagnostic performance and were shown to be suitable for use in screening CD in blood banks, isolated (IBMP-8.4) or in combination; and their use in blood banks could significantly reduce unnecessary disposal of blood bags or the risk of T. cruzi transmission.

Prognostic value of electrocardiographic abnormalities in adults from the Brazilian longitudinal study of adults' health.

OBJECTIVE: Cardiovascular diseases (CVDs) are highly preventable non-communicable diseases. ECG is a potential tool for risk stratification with respect to CVD. Our aim was to evaluate ECG's role in all-cause and cardiovascular mortality prediction. METHODS: Participants from the Brazilian Longitudinal Study of Adult Health, free of known CVD at baseline were included. A 12-lead ECG was obtained at baseline (2008-2010). Participants were followed up to 2018 by annual interviews. Deaths were independently reviewed. Cox as well as Fine and Grey multivariable regression models were applied to evaluate if the presence of any major electrocardiographic abnormality (MEA), defined according to the Minnesota Code system, would predict total and cardiovascular deaths. We also evaluated the Net Reclassification Index of adding MEA to the Systematic Coronary Risk Evaluation (SCORE). RESULTS: The 13 428 participants (median age 51 years, 45% men) were followed up for 8±1 years. All-cause and cardiovascular mortality occurred in 2.8% and 1.2% of the population, respectively. Prevalent MEA was an independent predictor of overall (HR=2.3, 95% CI 1.7 to 2.9) and cardiovascular mortality (HR=4.6, 95% CI 3.0 to 7.0) after adjustments for age, race, education and traditional cardiovascular risk factors. Adding MEA to the SCORE resulted in 9% mis-reclassification in the non-event subgroup and 33% correct reclassification in those with a fatal cardiovascular event. CONCLUSION: Presence of MEA was an independent predictor of overall and cardiovascular mortality. ECG may have a role in risk prediction of cardiovascular mortality in primary care.

Evidence of New Endemic Clusters of Human T-Cell Leukemia Virus (HTLV) Infection in Bahia, Brazil.

BACKGROUND: Salvador, Bahia (northeastern Brazil), has been identified as the epicenter of Human T-cell leukemia virus Human T-cell leukemia virus (HTLV) type 1 infection in the country. This study aims to estimate the rate of HTLV infection and the geographical distribution of this virus in this state. METHODS: All HTLV tests (chemiluminescence/ELISA assays/Western Blotting) performed in the Central Laboratory of Public Health of Bahia (LACEN) from 2004 to 2013 were included. Data was extracted from LACEN's database using high volume extract, transformation and load throughput. Infection rate was expressed as the number of infected individuals per 100,000 inhabitants considering municipalities grouped in microregions and/or mesoregions as the unit of analysis. RESULTS: A total of 233,876 individuals were evaluated. Individuals were from 394 out of 417 municipalities of Bahia (94.5%). HTLV chemiluminescence/ELISA assay was found to be reactive for 3,138 individuals from whom 2,323 had WB results (1,978 positives, 62 negative and 282 indeterminate). Out of 1978 reactive samples, 1,813 (91.7%) were positive for HTLV-1, 58 (2.9%) for HTLV-2 and 107 (5.4%) were for both HTLV-1 and HTLV-2. The cumulative mean rate of HTLV-positive cases in Bahia was 14.4 per 100,000 inhabitants. Three microregions presented rates >20 HTLV-positive cases/100,000 inhabitants: Barreiras (24.83 cases per 100,000 inhabitants), Salvador (22.90 cases per 100,000 inhabitants), and Ilhéus-Itabuna (22.60 cases per 100,000 inhabitants). CONCLUSION: HTLV infection is disseminated in the state of Bahia, with an overall moderate rate of infection. Further studies should be conducted to characterize the epidemiological and clinical profile of HTLV-infected individuals better and to propose effective prevention measures.

Proposed criteria for the identification of polycystic ovary syndrome following menopause: An ancillary study of the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil).

OBJECTIVES: To propose plausible criteria with which to identify menopausal women with PCOS. STUDY DESIGN: A cross-sectional study involving the baseline data of 713 menopausal women at admission to the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) in Salvador, Bahia, Brazil. MAIN OUTCOME MEASURES: PCOS was identified by the presence of two of three criteria. (1) A history of amenorrhea or oligomenorrhea (OL) (regular intermenstrual intervals ≥35 days during reproductive life); (2) clinical or biochemical hyperandrogenism (HA), identified by a score ≥5 points in a hirsutism questionnaire constructed and validated for women in this age group, or total or free testosterone ≥ the 95th percentile for women considered normal; (3) insulin resistance (IR) (a homeostatic model assessment [HOMA] index≥2.2). Validation was performed using probable epidemiological endpoints. RESULTS: According to these criteria, 7.6% of the women in the sample had PCOS. Of these, 7.4% had HA and OL, 72.2% had HA and IR, 14.8% had OL and IR and 5.6%, had HA, OL and IR. Women with PCOS were younger, had had fewer pregnancies and entered menopause earlier. Positive associations were found between PCOS and overweight (PR: 1.31; 95%CI: 1.18-1.46), obesity (1.44; 1.01-2.06), carbohydrate metabolism disorders (impaired glucose tolerance and diabetes mellitus) (1.30; 1.03-1.65), and with diabetes alone (1.41; 0.83-2.39), although this latter association failed to reach statistical significance. CONCLUSION: The women selected in accordance with these criteria had the characteristics of PCOS that are not only expected, but also widely associated with this disorder.

HTLV-1 in pregnant women from the Southern Bahia, Brazil: a neglected condition despite the high prevalence.

BACKGROUND: As the most frequent pathway of vertical transmission of HTLV-1 is breast-feeding, and considering the higher prevalence in women, it is very important to perform screening examinations for anti-HTLV-1 antibodies as part of routine prenatal care. So far, no studies of HTLV-1 seroprevalence in pregnant women in the Southern region of Bahia, Brazil, have been described. METHODS: Pregnant women were selected at the two regional reference centers for health care from Southern Bahia. A total of 2766 pregnant women attending the antenatal unit between November 2008 and May 2010 have been analyzed. An extra blood sample was drawn during their routine antenatal testing. A standardized questionnaire was applied and all positive plasma samples were tested by ELISA and were confirmed by Western Blot and PCR. Besides that, positive women were contacted and visited. The family members that were present during the visit were asked to be serologically screened to the virus. A prospective study was also carried out and newborns were followed up to two years for evaluation of vertical transmission. RESULTS: HTLV prevalence was 1.05% (CI 95%: 0.70-1.50). There was no association of HTLV-1 infection with age, education, income and ethnic differences. The association with marital status was borderline (OR = 7.99; 95% CI 1.07-59.3; p = 0.042). In addition, 43 family members of the HTLV-1 seropositive women have been analyzed and specific reactivity was observed in 32.56%, including two children from previous pregnancy. CONCLUSION: It is very important to emphasize that the lack of HTLV-1 screening in pregnant women can promote HTLV transmission especially in endemic areas. HTLV screening in this vulnerable population and the promotion of bottle-feeding for children of seropositive mothers could be important cost-effective methods to limit the vertical transmission. Besides that, our data reinforce the need to establish strategies of active surveillance in household and family contacts as important epidemiological surveillance actions for the early detection of virus infection and the prevention of transmission by sexual or and parenteral contact.

[Quality of abortion care in the Unified Health System of Northeastern Brazil: what do women say?]. / Qualidade da atenção ao aborto no Sistema Único de Saúde do Nordeste brasileiro: o que dizem as mulheres?

Abortion is a serious health problem in Brazil and complications can be avoided by adequate and timely care. The article evaluates the quality of care given to women admitted for abortion in hospitals operated by the Unified Health System, in Salvador, Recife and São Luis, the benchmarks being Ministry of Health norms and user satisfaction. The article analyzes 2804 women admitted to hospital for abortion complications in 19 hospitals, between August and December 2010. Four dimensions were defined: reception and guidance; inputs and physical environment; technical quality and continuity of care. There was a closer fit to norms on reception and guidance. Social support and the right to information were not well rated in all three cities. The technical quality of care was rated poor. With respect to inputs and physical environment, cleanliness was the least adequate criterion. Continuity of care was the most critical situation in all three cities, due to the lack of scheduled follow-up appointments, information about care available after hospital discharge, the risk of further pregnancy and family planning. Abortion care falls short of that advocated under Brazilian norms and by international agencies.

The role of education level in the intergenerational pattern of adolescent pregnancy in Brazil.

CONTEXT: Adolescent pregnancy has been associated with the early childbearing experience of the mothers of adolescents, and young people's education level is believed to be an important factor in this phenomenon. METHODS: In 2002, a representative household survey collected data from 3,050 young men and women aged 20-24 in three Brazilian cities. The main measures were mother's age at first birth, daughter's age at first pregnancy and son's age when he first impregnated a partner; ages were dichotomized as younger than 20 and 20 or older. The distribution of respondents by both their own and their mothers' reproductive experience was analyzed in relation to various characteristics, and logistic regressions assessed possible associations between these variables and pregnancy experience. RESULTS: Thirty percent of women reported getting pregnant before age 20, and 21% of men said they were younger than 20 when they first impregnated a partner. Of these groups, 34% of women and 31% of men reported that their mothers had first given birth at the same age. Both women and men were more likely to have had an early pregnancy experience if their mother had had a child before age 20 (odds ratios, 2.0 and 2.3, respectively). Among women, this positive association disappeared in the final model after adjusting for their education level, whereas among men the association remained after similar adjustment (1.8). CONCLUSIONS: Daughters' and sons' level of education appears to be an important factor in the repetition of adolescent fertility across generations. Efforts are needed to increase access to education and to encourage young people to remain in school.

[Contraceptive use among adolescents at public schools in Brazil]. / Uso de contracepção por adolescentes de escolas públicas na Bahia.

OBJECTIVE: There has been a growing interest in patterns of contraceptive use among adolescents, due, in particular, to the social relevance attached to pregnancy in this age group. Therefore, the objective of the study was to investigate factors associated with the use of contraceptive methods among female and male adolescent students. METHOD: A cross-sectional study was conducted, by means of self-applied questionnaires, among 4,774 students ranging from 11 to 19 years of age. Prevalence with respect to the use of contraceptive methods during the first experience of sexual intercourse as well as the most recent one was calculated both separately, that is, for each of these events, and in conjunction as a measure of consistent use. Logistic regression was carried out for simultaneous analysis of factors associated with the use of contraceptive methods and in order to calculate adjusted measures. RESULTS: Among the 1,664 students who reported being sexually active, the factors positively associated with the consistent use of contraceptive methods among male students included a) postponing their first experience of sexual intercourse and interaction with a stable partner, b) the family as a potential supplier of contraceptive methods, and c) access to health services. On the other hand, among female students factors positively associated with the consistent use of contraceptive methods included a) recent sexual initiation, and b) having a father as their source of information regarding sexuality, contraception and STD/AIDS prevention. Pregnancy was reported by 6.4% of the boys and 18.1% of the girls, its absence was associated with the consistent use of contraceptives by them (the girls) (Odds Ratio=3.83; 2.06-7.15). CONCLUSIONS: The results confirm the complexity of determining contraceptive behavior among adolescents and therefore reinforce the need to include multi-dimensional aspects of this theme in order to ensure the efficacy of sex education programs.
