Uso de psicofármacos durante la gestación: necesidad vs seguridad / Use of psychotropic drugs during pregnancy: necessity vs Safety

Resumen La seguridad de los psicofármacos durante el embarazo es un tema crucial en la práctica clínica. En esta revisión, se hace un breve recorrido sobre los cambios en el embarazo que impactan en la farmacodinamia de los medicamentos, además, se analizan los principales grupos farmacológicos en psiquiatría y sus efectos durante el embarazo. Se identifican tres períodos críticos durante el embarazo. El período de las primeras dos semanas se asocia con un mayor riesgo de aborto espontáneo. El período de la segunda a la décima semana es el más riesgoso, ya que pueden ocurrir alteraciones teratogénicas que afectan el desarrollo fetal. El período posterior a la décima semana se caracteriza por alteraciones en el crecimiento y desarrollo funcional del feto, pero suelen ser menos graves. Los antidepresivos, especialmente los inhibidores selectivos de la receptación de serotonina (ISRS) y los antipsicóticos de segunda generación se consideran los más seguros, pero estos últimos pueden estar asociados con síndrome metabólico, cardiopatías congénitas y trastornos del neurodesarrollo. El litio se ha asociado con efectos teratogénicos y malformaciones cardíacas, mientras que el valproato está relacionado con defectos congénitos importantes. Las benzodiacepinas pueden tener efectos tóxicos y causar síndrome de abstinencia en el recién nacido. La seguridad de los psicofármacos durante el embarazo requiere una evaluación individualizada de los beneficios y riesgos. Aunque algunos grupos de psicofármacos se consideran relativamente seguros, es necesario tener precaución y considerar las posibles complicaciones asociadas con su uso durante el embarazo.

Abstract: The safety of psychoactive drugs during pregnancy is a crucial issue in clinical practice. In this review, a brief overview of the changes in pregnancy that impact the pharmacodynamics of drugs is made; in addition, the main pharmacological groups in psychiatry and their effects during pregnancy are analyzed. Three critical periods during pregnancy are identified. The period of the first two weeks is associated with an increased risk of miscarriage. The period from the second to the tenth week is the most at risk , since teratogenic effects that affect fetal development can take place. The period after the tenth week is characterized by alterations in fetal growth and functional development , however ,less severe defects. Antidepressants, especially selective serotonin reuptake inhibitors (SSRIs), and second-generation antipsychotics are considered the safest, but the latter may be associated with metabolic syndrome, congenital heart disease, and neurodevelopmental disorders. Lithium has been associated with teratogenic effects and cardiac malformations, while valproate is associated with major birth defects. Benzodiazepines can have toxic effects and cause Neonatal Withdrawal Syndrome . The safety of psychotropic drugs during pregnancy requires an individualized assesment of the benefits and risks. Although some groups of psychiatric drugs are considered relatively safe, caution is needed when considering the potential complications associated with their use during pregnancy.

Calcium carbonate supplementation for the prevention of preeclampsia in high-risk pregnant women: a randomized clinical trial protocol.

BACKGROUND: Preeclampsia (PE) is a significant cause of maternal mortality worldwide, affecting 2% to 8% of pregnancies. The World Health Organization recommends the use of low-dose acetylsalicylic acid (100 mg of aspirin) and 1.5 to 2 g of calcium carbonate during pregnancy to prevent PE. However, robust evidence supporting the efficacy of calcium supplementation is still needed. This study aims to assess the efficacy of calcium carbonate in preventing preeclampsia in high-risk pregnant women. METHODS: A triple-blind, randomized clinical trial will be conducted at an outpatient clinic in Brazil between May 2024 and March 2026. Pregnant women at high risk of developing preeclampsia and with low dietary calcium intake will be randomly assigned to one of three groups: one group will receive calcium carbonate capsules (commercially available in Brazil) along with 100 mg of aspirin; the second group will receive calcium carbonate derived from Crassostrea sp. along with 100 mg of aspirin; and the control group will receive a placebo alongside 100 mg of aspirin. The primary outcome is the diagnosis of preeclampsia during pregnancy, while secondary outcomes evaluate maternal and fetal health indicators. DISCUSSION: This trial seeks to generate evidence on the efficacy of calcium carbonate in preeclampsia prevention, with a focus on comparing industrial calcium carbonate with calcium carbonate sourced from Crassostrea sp., a more sustainable alternative. TRIAL REGISTRATION: The study was approved by the Research Ethics Committee of the Federal University of Sergipe and registered in the Brazilian Registry of Clinical Trials (ReBEC), under the ID RBR-7hqhj3y. Registered on November 16, 2023.

Integrase strand transfer inhibitors resistance-associated mutations in HIV-infected pregnant women.

OBJECTIVE: To date, no data exist regarding the prevalence of integrase inhibitor (INSTI) resistance-associated mutations (HIVDRM) in HIV-infected pregnant women (HPW) in Latin America. We describe the prevalence and transmissibility of integrase HIVDRM in a historical cohort of INSTI-naïve HPW from Argentina (n=56) with Next Generation Sequencing (NGS). METHODS: Bioinformatics analysis was performed by HyDRA software for 20%, 10%, 5%, 2%, and 1% sensitivity thresholds. We calculated the mutational viral load for each INSTI-HIVDRM, considering those with >1000 c/mL as of high risk of transmissibility. RESULTS: The predominant HIV subtype was BF (78.5%). Major HIVDRM were not detected with the population sequencing 20% filter. With a 1% threshold, the prevalence increased to 8.9%; Y143C/S, E92G, E138K, and T66I mutations were found. The median (range) mutational load (expressed in c/mL) was: 355 (50.2-11705); with only 1 case >1000 c/mL Accessory mutations (G163R/K, T97A) were detected mostly with a 20% sensitivity threshold with an overall prevalence of 23.2%; the median (IQR) mutational load was: 23929 (4009-63158) c/mL; all of them above 1000 c/mL. CONCLUSIONS: Our results show evidence of the presence of major INSTI-HIVDRM as aleatory mutations and a high frequency of accessory mutations with potential transmissibility in HPW.

Neonatal and maternal outcomes of mRNA versus Non-mRNA COVID-19 vaccines in pregnant patients: a systematic review and meta-analysis.

Objective: To compare the effectiveness and safety of non-mRNA versus mRNA COVID-19 vaccines on pregnant women and their newborns in a systematic review with meta-analysis. Data sources: We searched PubMed, Embase, and Cochrane Central in May 2023. Study selection: The search strategy yielded 4451 results, 16 studies were fully reviewed. We selected case-control studies analysing non-mRNA versus mRNA vaccines. Data collection and analysis: we assessed the risk of bias using the Cochrane Risk of Bias in Non-randomized Studies of Interventions (ROBINS-I) tool. Standardised mean differences were pooled using random-effect models. Data synthesis: We identified 8 prospective and retrospective studies with a total of 32,153 patients. Non-mRNA vaccines were associated with a higher incidence of fever (OR 2.67; 95% CI 2.08-3.43; p<0.001), and a lower incidence of fetal or neonatal death (OR 0.16; 95% CI 0.08-0.33; p<0.001). In subgroup analyses, the Jansen vaccine (Ad26.COV2.S) was found to have a higher rate of premature labor/delivery (OR 4.48; 95% CI 1.45-13.83; p=0.009) and missed/spontaneous abortion (OR 1.90; 95% CI 1.09-3.30; p=0.02), as compared with the Pfizer (BNT162b2) vaccine. Conclusion: non-mRNA vaccines are associated with a lower incidence of fetal or neonatal death among pregnant women who receive a Covid19 vaccine, although at an increased rate of pyrexia compared with mRNA vaccines. Other studies are required for better assessment. PROSPERO: CRD42023421814.

Association between dietary patterns and infant birth weight in brazilian pregnancy women with gestational diabetes: a cross-sectional study.

Objective: To evaluate the association between the dietary patterns (DPs) of pregnant women with GDM (gestational diabetes mellitus) and the birth weight (BW) of the infants. Methods: Cross-sectional study with 187 adult pregnant women with GDM attended at a maternity in Rio de Janeiro from 2011 to 2014. Dietary intake was assessed in the third trimester using a semiquantitative food frequency questionnaire (FFQ). The outcomes were BW and weight adequacy for gestational age (GA). Reduced Rank Regression (RRR) was used to explain the following response variables: density of carbohydrates, fibres, and saturated fatty acids. Statistical analyzes included multinomial logistic regression models. Results: The mean BW was 3261.9 (± 424.5) g. Three DPs were identified, with DP 3 (high consumption of refined carbohydrates, fast foods/snacks, whole milk, sugars/sweets, and soft drinks and low consumption of beans, vegetables, and low-fat milk and derivatives) being the main pattern, explaining 48.37% of the response variables. In the multinomial logistic regression analysis no statistically significant association was found between the tertiles of DPs and BW or the adequacy of weight for GA, even after adjustments of confounding covariates. Conclusion: No significant associations were found between maternal DPs in the third trimester of pregnancy and infant BW or adequacy of weight for GA.

Prevalence of syphilis and associated factors among pregnant women in Brazil: systematic review and meta-analysis.

Objective: This systematic review accompanied by a meta-analysis aimed to estimate the prevalence of syphilis in pregnant women in Brazil and describe its associated factors. Methods: Following the establishment the search strategies and the registration of the review protocol in PROSPERO, we conducted a search for relevant articles in the Pubmed, LILACS, Science Direct, SciELO and Web of Science databases. Our inclusion criteria were cross-sectional studies published between 2005 and 2023, with no language restrictions. The combined prevalence of syphilis infection was estimated using the random effects model in the R Software with a 95% confidence interval (95% CI) and p < 0.01 as statistically significant. Results: A total of 24 articles were recruited, which together investigated 221,884 women. The combined prevalence of syphilis in pregnant women in Brazil was 1.79% (95% CI: 1.24-2.57%), and the main factors associated with its occurrence were black and brown skin color, low education and factors related to the partner. Conclusion: There was a high prevalence of syphilis in pregnancy in Brazil, mainly associated with socioeconomic factors.

Impact of education on knowledge, attitudes, and practices for gestational toxoplasmosis.

BACKGROUND: Toxoplasmosis is potentially avoidable, treatable, and curable by simple and direct preventive measures. Knowledge, attitudes, and practices (KAP) assessments concerning gestational toxoplasmosis were evaluated in a cohort of pregnant women from Armenia-Quindío (Colombia, South America). METHODS: This cross-sectional descriptive KAP-type study was performed with informed consent between October 2021 and March 2022. The intervention involved a ten-minute talk administered by prenatal clinic nurses to pregnant women. This took place in the public health clinic RedSalud and the private clinic Happy Maternity with a post-KAP survey after pregnancy. RESULTS: The findings of the initial KAP survey revealed that approximately 42.8 % of the 250 mothers surveyed had IgG anti-T. gondii antibodies present. A strong correlation was observed between a lower frequency of antibodies and a higher level of education. Following an educational intervention, 73 seronegative women demonstrated a significant improvement in their knowledge and behavior. Among the 111 mothers who received the intervention, 42 (37 %) were followed until delivery. Unfortunately, their level of compliance with prenatal serological follow-up was lower compared to previous historical records of cohort of mothers in the same health center during pre-pandemic periods. No seroconversion occurred, although the small number of cases makes the outcome inconclusive with respect to statistical significance. CONCLUSIONS: Education plays a crucial role in imparting valuable knowledge and fostering effective practices. It holds significant potential to prevent toxoplasmosis in pregnant seronegative mothers. Prenatal check-ups have proven to be a critical determinant in leveraging the benefits of education for seronegative mothers. Reporting and observed behaviors differed, identifying areas for improvement.

A Retrospective Cross-Sectional Analysis of Viral SARI in Pregnant Women in Southern Brazil.

Pregnant women (PW) are at a higher risk of diseases and hospitalization from viral respiratory infections, particularly influenza and SARS-CoV-2, due to cardiopulmonary and immunological changes. This study assessed the impact of viral respiratory infections on PW hospitalized with severe acute respiratory infection (SARI) prior to the COVID-19 pandemic. It is a cross-sectional study with 42 PW and 85 non-pregnant women (NPW) admitted with SARI to two tertiary hospitals between January 2015 and December 2019. The rates of virus prevalence, SARI hospitalization, length of hospital stay, oxygen supplementation, intensive care unit (ICU) admission, and death were comparable between PW and NPW. A multivariate analysis showed that PW had a higher rate of viral SARI hospitalizations (OR = 2.37; 95% CI = 1.02-5.48) as compared to NPW, with the influenza virus being the most prevalent (aOR = 7.58; 95% CI = 1.53-37.66). The length of hospital stays (aOR = 0.83; 95% CI = 0.73-0.95) and admissions to the ICU (aOR = 0.028; 95% CI = 0.004-0.25) were lower in PW as compared to hospitalized NPW. The influenza virus had a greater impact on the frequency of SARI in the group of PW, and these had a better outcome than NPW due to the earlier antiviral treatment they received.

High Prevalence of Syphilis among Young Pregnant Women in the Brazilian Amazon: A Cross-Sectional Study Based on Clinical Records in a Public Health Reference Unit in the City of Belém.

BACKGROUND: Syphilis remains a significant global public health concern, and one of its consequences in pregnant women is the potential occurrence of congenital syphilis due to Treponema pallidum infection. This study determined the prevalence of syphilis among pregnant women undergoing prenatal care in a neighborhood on the outskirts of the city of Belém, Brazilian Amazon. METHODS: This cross-sectional study used data from clinical records of 611 pregnant women who underwent prenatal care at a public health unit in 2019 and 2020. The reagent result for VDRL was used as an indicator of syphilis. Odds Ratio and chi-square tests were used to evaluate the association of information from pregnant women with syphilis. RESULTS: The overall prevalence of syphilis was 5.2 % (32/611; 95 % CI: 3.5-7.0 %). Age under 23 years was identified as a risk factor for syphilis. CONCLUSIONS: The prevalence of syphilis among pregnant women in the outskirts of Belém is high, especially among younger women. There is an urgent need to intensify innovative sexual and reproductive health education initiatives and emphasize the importance of consistent practice of preventive measures against syphilis and other STIs in the Amazon region, especially in the young population.

Molecular characterization, antimicrobial resistance and invasion of epithelial cells by Streptococcus agalactiae strains isolated from colonized pregnant women and newborns in Rio de Janeiro, Brazil.

AIMS: To evaluate the prevalence, molecular characteristics, antimicrobial susceptibility, and epithelial invasion of Streptococcus agalactiae strains isolated from pregnant women and newborns in Rio de Janeiro, Brazil. METHODS AND RESULTS: A total of 67 S. agalactiae isolates, 48 isolates from pregnant women and 19 from neonates, were analyzed. Capsular type Ia and V were predominant (35.8%/each). The multilocus sequence typing analysis revealed the presence of 19 STs grouped into 6 clonal complexes with prevalence of CC17/40.3% and CC23/34.3%. The lmb and iag virulence genes were found in 100% of isolates. Four S. agalactiae strains, belonging to CC17/ST1249 and CC23/ST23, were able to adhere to A549 respiratory epithelial cells. Antimicrobial resistance was verified mainly to tetracycline (85%), erythromycin (70.8%), and clindamycin (58.3%). Four S. agalactiae isolates were multidrug resistant. The resistance genes tested were found in 92.5% of isolates for tetM, 58.2% for ermB, 28.4% for mefAE, and 10.4% for tetO. CONCLUSION: The study showed a high prevalence of virulence and antimicrobial genes in S. agalactiae strains isolated from pregnant women and newborns, supporting the idea that continued surveillance is necessary to identify risk factors and perform long-term follow-up in pregnant women and neonates in Rio de Janeiro.

Association between Liver and Kidney Function and Birth Outcomes in Pregnant Surinamese Women Exposed to Mercury and Lead in the Caribbean Consortium for Research in Environmental and Occupational Health (CCREOH) Environmental Epidemiologic Cohort Study.

Exposure to mercury (Hg) and lead (Pb), in combination with liver and kidney impairment, may result in adverse birth outcomes. From 408 women in the age range of 16 to 46 years, living in rural and urban areas in the interior of Suriname, we looked at the association between adverse birth outcomes and exposure to Hg and Pb in combination with liver and kidney function. This group of women represented a subcohort of pregnant women who participated in the Caribbean Consortium for Research in Environmental and Occupational Health (CCREOH)-Meki Tamara study. Liver function was assessed by measuring aspartate amino transferase (AST), alanine amino transferase (ALT), and gamma-glutamyl transferase (GGT). Kidney function was assessed by measuring creatinine, urea, and cystatin C. We defined preterm births as birth before 37 weeks of gestation, low birthweight as birthweight < 2500 g, and low Apgar score as a score < 7 at 5 min, and these were used as indicators for adverse birth outcomes. Small size for gestational age was defined as gestational age < -2SD weight for GA. We found significant statistical associations between biomarkers for liver and kidney functions and adverse birth outcomes Apgar score and gestational age. No significant association was found between heavy metals Hg and lead and adverse birth outcomes.

Spatial and trend analysis of gestational syphilis cases in Brazil from 2011 to 2020: an ecological study.

OBJECTIVES: To analyze the rate of gestational syphilis (GS) based on temporal trends over 11 years, as well as the spatial distribution of GS in Brazil, based on the identification of spatial clusters. METHODOLOGY: An ecological, using Brazil and its regions as an analysis unit, based on gestational syphilis data reported in the Notifiable Diseases Information System (SINAN), from 2011 to 2020. Thematic maps were built for spatial data analysis, and the Prais-Winsten autoregressive model was used to verify the trend. Spatial analysis identified the distribution of clusters (high-high; low-low; high-low and low-high) of distribution of GS across Brazilian municipalities, using a 5% significance level. RESULTS: Gestational syphilis experienced a considerable increase in cases during the studied period, with a peak of 37,436 cases in 2018. The spatial distribution of the disease is heterogeneous in the country. A growing trend was observed in all states of Brazil, except for Espírito Santo, where it remained stationary, with a monthly variation of 10.32%. CONCLUSION: The spatial and temporal trend analysis point to syphilis as an important public health problem. The numbers are alarming and show the urgent need for measures to prevent and control syphilis during pregnancy.

Pregnant women's perceptions on Information Sources on Zika Virus: a qualitative study.

The Zika virus (ZIKV) epidemic had a sanitary, psychosocial, and economic impact on individuals of reproductive age. The primary concern revolved around infection during pregnancy due to possible vertical transmission and its association with adverse fetal and infant outcomes, known as Congenital Zika Syndrome (CZS). This qualitative study employs phenomenology and grounded theory. This study includes interviews with 98 women, some pregnant during the ZIKV epidemic in Brazil, Colombia, and Puerto Rico, who had children with CZS or without diagnosed neurological impairment. Additionally, the study included a group of women who were pregnant during the COVID-19 pandemic in these same countries. In both groups, interviewees had varying levels of knowledge about ZIKV. The study found that messages conveyed through the media tended to be alarmist, in contrast to the information provided by healthcare professionals, which was considered more trustworthy. Pregnant women during the ZIKV epidemic reported receiving their ZIKV and CSZ infection diagnoses late, either during or after childbirth. The study underscores the needs of pregnant women in high-risk scenarios, the importance of health education processes, and the necessity to reinforce communication and continuing education.

A epidemia do vírus Zika (ZIKV) teve impacto sanitário, psicossocial e econômico sobre pessoas em idade reprodutiva. A principal preocupação foi a infecção durante a gravidez devido a possível transmissão vertical e sua associação com resultados fetais e infantis adversos, conhecida como síndrome congênita associada à infecção pelo Vírus Zika (SCZ). Este estudo qualitativo utiliza a fenomenologia e a teoria fundamentada. O estudo inclui entrevistas com 98 mulheres, parte grávida durante a epidemia de ZIKV no Brasil, Colômbia e Porto Rico e que tiveram filhos com SCZ ou sem comprometimento neurológico diagnosticado. Além disso, o estudo inclui um grupo de mulheres grávidas durante a pandemia de COVID-19 nos mesmos países. Em ambos os grupos, as entrevistadas tinham diferentes níveis de conhecimento sobre ZIKV. O estudo constatou que as mensagens veiculadas por meio da mídia eram alarmistas; em contraste com as informações fornecidas por profissionais de saúde, consideradas mais confiáveis. Mulheres gestantes durante a epidemia do ZIKV relataram ter recebido seu diagnóstico de infecção por ZIKV e SCZ tardiamente ou após o parto. O estudo destaca as necessidades das mulheres grávidas em cenários de alto risco, a importância de processos de educação em saúde e a necessidade de reforçar a comunicação e a educação continuada.

Caries is a multifactorial disease that affects the hard tissues of the tooth. By evaluating the risk of caries, it is possible to determine the probability of its incidence during a certain period of time. The objective was to determine the oral health status of pregnant women and its relationship with caries risk factors. A clinical observational descriptive study was carried out. The population was made up of pregnant women who attended the Ángela Llano Hospital in the city of Corrientes for care. A clinical history was prepared, and the oral health status and caries risk were determined according to the CAMBRA protocol. Univariate statistics were used to characterize and describe the data. The results achieved were Caries Index from 4.5 to 6.5, in the Plaque index the mean ± SD 56.8% ± 39.9% Min: 28.5%/ Max: 90.9%. Regarding the pH value of 7.11 ±0.43, Min.: 7.00, Max.: 8.67. Salivary flow: mean ± SD: 0.58 ml/m ± 0.28 ml/m Min.: 0.2 ml/m Max.: 0.62 ml/m; Average age: 22 years. Min.:18 Max.: 33 years.

The presence of SM can considerably increase the risk of caries, if the host defense mechanisms do not override the bacteria (AU)

Neuroserpin, IL-33 and IL-17A as potential markers of mild symptoms of depressive syndrome in Toxoplasma gondii-infected pregnant women.

Introduction: Depressive syndrome (DS) is a common complication during pregnancy and the postpartum period, and is triggered by multiple organic/genetic and environmental factors. Clinical and biochemical follow-up is essential for the early diagnosis and prognosis of DS. The protozoan Toxoplasma gondii causes infectious damage to the fetus during parasite primary-infection. However, in long-term infections, pregnant women develop immune protection to protect the fetus, although they remain susceptible to pathological or inflammatory effects induced by T. gondii. This study aimed to investigate plasma inflammatory biomarkers in pregnant women seropositive and seronegative for T. gondii, with diagnoses of minor and moderate/severe DS. Methods: Pregnant women (n=45; age=18-39 years) were recruited during prenatal care at health centers in Ouro Preto, Minas Gerais, Brazil. Participants were asked to complete a socio-demographic questionnaire to be submitted to well-standardized DS scale calculators (Beck Depression Inventory Questionnaire, Edinburgh Postnatal Depression Scale, and Major Depressive Episode Module). Additionally, 4 mL of blood was collected for plasma neuroserpin, CCL2, IL-17A, and IL-33 analysis. Results: Pregnant volunteers with chronic T. gondii contact were all IgG+ (44%; n=21) and exhibited increased plasma IL-33, IL-17A, and neuroserpin levels, but not CCL2, compared to uninfected pregnant women. Using Beck's depression inventory, we observed an increase in plasma IL-17A and IL-33 in women with T. gondii infeCction diagnosed with mild DS, whereas neuroserpin was associated with minor and moderate/severe DS. Discussion: Our data suggest a close relationship between DS in pregnant women with chronic T. gondii infection and neurological conditions, which may be partially mediated by plasma neuroserpin, IL-33, and IL-17A levels.

Influences on COVID-19 Vaccine Adherence among Pregnant Women: The Role of Internet Access and Pre-Vaccination Emotions.

INTRODUCTION: The onset of the COVID-19 pandemic brought about global uncertainties and fears, escalating the dissemination of fake news. This study aims to analyze the impact of fake news on COVID-19 vaccine adherence among pregnant women, providing crucial insights for effective communication strategies during the pandemic. METHODS: A cross-sectional, exploratory study was conducted with 113 pregnant women under care at a Women's Health Reference Center. Data analysis included relative frequency and odds ratio to assess the relationship between sociodemographic and behavioral variables regarding vaccination. RESULTS: In the behavioral context of vaccination, internet access shows a significant association with decision-making, influencing vaccine refusal due to online information. Nuances in the odds ratios results highlight the complexity of vaccine hesitancy, emphasizing the importance of information quality. Pre-vaccination sentiments include stress (87.61%), fear (50.44%), and anxiety (40.7%), indicating the need for sensitive communication strategies. DISCUSSION: Results revealed that pregnant women with higher education tend to adhere more to vaccination. Exposure to news about vaccine inefficacy had a subtle association with hesitancy, while finding secure sources was negatively associated with hesitancy. The behavioral complexity in the relationship between online information access and vaccination decision underscores the need for effective communication strategies. CONCLUSIONS: In the face of this challenging scenario, proactive strategies, such as developing specific campaigns for pregnant women, are essential. These should provide clear information, debunk myths, and address doubts. A user-centered approach, understanding their needs, is crucial. Furthermore, ensuring information quality and promoting secure sources are fundamental measures to strengthen trust in vaccination and enhance long-term public health.

Effect of Treating Periodontal Disease in Pregnant Women to Reduce the Risk of Preterm Birth and Low Birth Weight: An Umbrella Review.

Background: The aim of this review was to evaluate the effects of periodontal disease (PD) treatment in pregnant women to reduce the risk of preterm birth (PB) and low birth weight (LBW) by conducting an umbrella review. Methods: A comprehensive search for the literature up to April 2024 was conducted across multiple databases including PubMed, Cochrane Library, Scopus, EMBASE, Scielo, Web of Science, Google Scholar, Proquest Dissertations and Theses, and OpenGrey. We specifically targeted systematic reviews (SRs) with or without meta-analyses, irrespective of language or time constraints, focusing on primary studies examining the effect of PD treatment in pregnant women to reduce the risk of PB and LBW. Various types of non-systematic reviews, intervention studies, observational studies, preclinical and basic research, summaries, comments, case reports, protocols, personal opinions, letters, and posters were excluded from consideration. The quality and overall confidence of the included studies were assessed using the AMSTAR-2 tool. Results: After the initial search, 232 articles were identified, of which only 24 met the selection criteria after exclusion. The majority of these studies indicated that periodontal treatment reduces the risk of PB and LBW. Conclusions: According to the findings and conclusions drawn from the SRs with a high overall confidence level, PD treatment in pregnant women reduces the risk of PB and LBW.

Knowledge Gaps and Educational Opportunities in Congenital Toxoplasmosis: A Narrative Review of Brazilian and Global Perspectives.

Congenital toxoplasmosis is a parasitic disease caused by the transmission of the protozoan Toxoplasma gondii during pregnancy that can potentially cause severe consequences for the fetus or neonates. The disease disproportionately impacts the global population and is generally correlated with the Human Development Index. Despite its prevalence, there are knowledge gaps among pregnant women and healthcare providers regarding the prevention, diagnosis, and treatment of this condition. This narrative review aimed to examine the current state of knowledge of toxoplasmosis among both groups, with a focus on exploring the Brazilian and global perspectives and highlighting opportunities for enhancing education and communication. A search was conducted across five databases, and 60 studies were selected (23 in Brazil and 37 worldwide). Quantitative analysis revealed that general knowledge of toxoplasmosis among pregnant women is notably poor, with 66% of Brazilian women and 72% of women worldwide lacking sufficient understanding. Among those with some knowledge, the most recognized association is with cats (46% in Brazil and 38% worldwide), followed by raw or undercooked meat (27% in Brazil and 25% worldwide), and improperly sanitized vegetables or water (15% in Brazil and 21% worldwide). Similarly, gaps in knowledge were found among healthcare providers. Difficulty with IgG avidity test interpretation is higher in Brazil (43%) compared to worldwide (18%). The most recognized association is with cats (66% in Brazil and 74% worldwide), followed by raw or undercooked meat (49% in Brazil and 70% worldwide), and improperly sanitized vegetables or water (31% in Brazil and 32% worldwide). These findings emphasize the need for tailored local and global public health educational initiatives to enhance knowledge of toxoplasmosis among pregnant women and healthcare providers.

HIV in pregnant woman and children: Mother-to-child transmission of HIV in the Brazilian land border from 2010 to 2021.

OBJECTIVE: The aim of the present study was to analyze the profile and trends of HIV mother-to-child transmission (MTCT) in the Brazilian land border strip (LBS). METHODS: This was a quantitative, ecological, and cross-sectional study using secondary data available in the information systems of the Brazilian Ministry of Health. All cases reported in the Notifiable Diseases Information System between 2010 and 2021 were studied. RESULTS: Between 2010 and 2021, 275 children were born infected through MTCT, and 6076 pregnant women were living with HIV in the Brazilian LBS. HIV detection rates in pregnant women increased in all border arcs. The northern arc experienced the highest increase (19.6%), followed by the central arc (11.4%), and the southern arc (6.1%). Despite historically high detection rates, the southern arc exhibited the smallest increase. While MTCT rate decreased by 37.7% in the border area, the central arc showed no statistically significant reduction. In 2021, the average age of pregnant women was 26.2 years, 25.7% had up to 8 years of schooling, and 55.8% identified as non-white. The majority (92.8%) received antenatal care, and 59.7% were diagnosed with HIV before prenatal care. The use of prophylactic antiretroviral therapy during prenatal care occurred in 69.6% of pregnant women, and infant prophylaxis was provided within first 24 h to 43.6% of live births. CONCLUSION: The results indicate progress in reducing MTCT cases in Brazilian LBS. Disparities in HIV detection rates may be influenced by differences in testing uptake, despite mandatory testing for all babies. It is crucial to continue implementing strategies to reach these women and ensure equitable access to healthcare services for MTCT prevention.

Pregnant women's knowledge and clinical management of hemolytic disease of the fetus and newborn in Pará, Brazil.

OBJECTIVE: To evaluate the knowledge of pregnant women and the clinical management of hemolytic disease of the fetus and newborn, as well as to describe the gestational profile, risk factors and socio-epidemiological profile of pregnant women treated at two municipal health units in Belém (Pará, Brazil). METHODS: This was a cross-sectional analytical study, which consisted in the application of questionnaires to pregnant women who underwent prenatal care at the municipal health units. RESULTS: A total of 104 pregnant women were evaluated; most were aged between 24 and 29 years old, had high school degrees (38 %), family incomes between 1 and 2 minimum wages (45 %) and blood type O+ (43 %). Regarding the gestational profile, the participants were predominantly in the third trimester of pregnancy (49 %), started prenatal care in the first gestational trimester (81 %) and were primiparous (61 %). Failures in the management of prenatal care were observed, especially with regard to access to information about the disease, since most pregnant women did not receive information about blood incompatibility during prenatal care. This led to limited knowledge about the pathology of the disease evidenced by the fact that most of the correct answers were between Questions 0-4, which were significantly associated with the women's education and income. CONCLUSIONS: Although hemolytic disease of the fetus and newborn is serious, the pregnant women in this study demonstrated little knowledge about the disease and had inadequate care by health professionals, reinforcing the importance of improving care for women's health and prenatal care.
