RESUMEN

Preventive Chemotherapy (PC) refers to the use of medications, either individually or in combination, as a key public health tool aimed at controlling and eliminating neglected infectious diseases (NIDs). These diseases disproportionately affect vulnerable populations in low-income areas. By administering medications regularly, PC helps reduce the occurrence, transmission, and severity of NIDs, as well as the long-term complications associated with them. Enuring the safety of medications used in PC is not only a crucial technical consideration but also an ethical responsibility. It ensures that while providing health benefits to eligible populations, no harm is caused to individuals. This aligns with the fundamental principle of "do no harm" in medical practice. Furthermore, medication safety is essential for public health programs to succeed, as public trust in the safety and efficacy of these interventions is critical. From manufacturing, where medicines must meet strict quality standards, to the logistics of distribution within the supply chain, and finally, to their administration and the monitoring of any adverse effects, safety must be guaranteed at every stage. To support national NID programs in ensuring the safe administration of medications, organizations like PAHO and WHO, in partnership with strategic stakeholders, have developed a range of practical guidelines, training materials, and tools. These resources are designed to assist in the planning, preparation, and monitoring processes that ensure medication safety. This publication outlines how to access these resources online and is further supplemented by a detailed section of frequently asked questions and their corresponding answers, specifically focused on safety considerations during the implementation of PC.

RESUMEN

BACKGROUND: Atherosclerotic cardiovascular disease (ASCVD), affects approximately 18.6 million individuals worldwide, poses an important healthcare challenge. Despite the established efficacy of both high-intensity statin monotherapy (HIS) and moderate-intensity statin plus ezetimibe (MIS+EZT) in ASCVD management, the optimal treatment strategy remains unclear. PURPOSE: This meta-analysis seeks to assess the impact of moderate-intensity statin plus ezetimibe (MIS+EZT) versus high-intensity statin monotherapy (HIS) on LDL < 70mg/dl; Total Cholesterol; LDL; High Density Cholesterol (HDL) and triglycerides levels. Our goal is to synthesize the existing evidence and pinpoint areas that warrant further investigation. METHODS: A thorough literature search was conducted across PubMed, Scopus, Web of Science, and the Cochrane databases, focusing on studies that compared the effects of moderate-intensity statins plus ezetimibe with high-intensity statin monotherapy in ASCVD patients. RESULTS: In the 13 included studies, involving 8,592 patients, of which 4,525 (52.67%) received moderate-intensity statin plus ezetimibe treatment. The follow-up period ranged from 12 to 219 weeks, with participant ages varying from 66 to 76.5 years in the MIS+EZT group and from 67 to 75.9 years in the HIS group. Analysis revealed significant MIS+EZT-associated with greater percentages in Low Density Lipoprotein (LDL) < 70 (Odds Ratio (OR) 1.76; 95% CI [1.26; 2.45]; p=0.001; I²=73%), LDL reduction (Mean Difference (MD) -5.05 mg/dL; 95% CI [-9.02;-1.07]; p< 0.013; I²=56%;); Total Cholesterol reduction (MD -7.91 mg/ dL; 95% CI [-14.90; -0.91]; p< 0.027; I²=60%); Triglycerides reduction (MD -8.20 mg/ dL; 95% CI [-13.05; -3.35]; p< 0.001; I²=2%;); There was no statistical difference between groups in Drug Adverse reaction (Risk Ratio (RR) 1.19; 95% CI [0.79; 1.78]; p=0.404; I²=0%); and Drug intolerance (RR 0.78 ; 95% CI [0.32; 1.92]; p=0.584; I²=35%). CONCLUSIONS: This meta-analysis underscores the effectiveness of MIS+EZT in enhancing significant clinical outcomes for ASCVD patients, as evidenced by improvements in a greater percentage of patients achieved the LDL < 70 target, LDL, Total Cholesterol and Triglycerides levels . Importantly, there were no significant differences in the occurrence of overall adverse events and adverse drug reactions between the two groups.

RESUMEN

Contexto e objetivo: o abuso de androgênios não se restringe mais a atletas, uma vez que é utilizado pela população geral para melhora da massa muscular e performance física. Tais doses supra fisiológicas causam vários efeitos colaterais, incluindo psiquiátricos e reprodutivos. Demonstrar a importância dos diagnósticos de quadros psiquiátricos e sexuais, bem como da escolha dos psicotrópicos mais adequados para cada paciente. Métodos: Trata-se de uma revisão narrativa acerca da importância do quadro, bem como seu tratamento. Discussão: Não basta fazer o diagnóstico de abuso de andrógenos. Pesquisar e tratar possíveis quadros psiquiátricos, disfunções sexuais (DS), transtornos parafílicos (TP) e outras doenças somáticas é primordial. Medicações psiquiátricas podem prejudicar a atividade sexual ou não. Transtorno do Comportamento Sexual Compulsivo (TCSC), Transtornos Parafílicos e outras condições sexuais de risco podem exigir psicotrópicos que inibam a função sexual. Porém, o favorecimento de uma atividade sexual saudável, sem sofrimento, pode demandar drogas que causem pouco ou nenhum prejuízo à sexualidade. Conclusão: Conhecer os diagnósticos sexuais, psiquiátricos e clínicos e tratá-los adequadamente é de suma importância. Os mecanismos moleculares e patológicos envolvidos nos efeitos colaterais neuropsiquiátricos dos andrógenos não são claros. Mais pesquisas são necessárias.

RESUMEN

BACKGROUND: Chagas disease (CD) is a serious public health problem in Latin America. Benznidazole (BNZ) is used for the treatment of CD and, despite its wide use, little information is available about its toxicity and mechanisms of adverse drug reactions (ADR). OBJECTIVES: To identify and classify clinical and laboratory adverse reactions caused by BNZ in terms of causality and severity. METHODS: Prospective cohort study from January 2018 to December 2021. Treatment follow-up included visits and biochemical tests (complete blood count, liver and kidney function tests) before, during and after treatment. ADR were classified according to causality and severity. In the statistical analysis, the significance level was set at p<0.05. RESULTS: Forty patients with chronic CD were included. A high prevalence of ADR was observed 161 ADR in 30 patients [90%]; of these, 104 (64.6%) were classified as possible and 57 (35.4%) as probable. The ADR were classified as moderate and mild. Of the 40 patients, nine (22.5%) discontinued treatment. ADR associated with treatment discontinuation and interventions were those that affected the dermatological system, central and peripheral nervous system and sense organs such as ageusia. Mild hematological and biochemical changes such as lymphopenia were observed after 30 days of treatment. CONCLUSION: Many patients were able to complete the treatment even with ADR, which can be attributed to the successful follow-up strategy with symptomatic treatment and counseling, leading to patient's awareness of symptoms and treatment adherence.

FUNDAMENTO: A Doença de Chagas (DC) representa um grave problema de saúde pública na América Latina. O Benznidazol (BNZ) é utilizado para o tratamento DC e, apesar do seu amplo uso, poucas informações estão disponíveis sobre sua toxicidade e mecanismos das Reações Adversas ao Medicamento (RAM). OBJETIVOS: Identificar e classificar as reações adversas clínicas e laboratoriais ocasionadas pelo uso do BNZ quanto à sua causalidade e gravidade. MÉTODOS: Estudo de coorte prospectivo realizado no período de janeiro de 2018 a dezembro de 2021. O acompanhamento do tratamento incluiu consultas e análises laboratoriais antes, 30 e 60 dias após o início do tratamento. As RAM foram classificadas quanto à causalidade e gravidade. Na análise estatística o nível de significância adotado foi p<0,05. RESULTADOS: Participaram do estudo 40 pacientes com DC crônica, observou-se alta prevalência de RAM com um total de 161 em 30 (90%) pacientes. Destas, 104 (64,6%) foram classificadas como possíveis e 57 (35,4%) como prováveis. As reações foram classificadas em moderadas e leves. Dos 40 pacientes, nove (22,5%) suspenderam o tratamento. As RAM associadas à interrupção e intervenções foram as que afetaram o sistema dermatológico, sistema nervoso central e periférico ou que culminaram em ageusia. Após 30 dias de tratamento, alterações hematológicas e bioquímicas leves foram observadas como linfopenia. CONCLUSÃO: Apesar do elevado percentual de RAM, muitos pacientes foram capazes de completar o tratamento, o que se atribui ao êxito da estratégia de acompanhamento com intervenções de tratamento sintomático juntamente ao aconselhamento, levando à compreensão da sintomatologia e manutenção do tratamento.

RESUMEN

Adverse events (AEs), and particularly adverse drug events (ADEs), represent a health problem as they can cause permanent damage or death. Understanding the frequency, location, and causes of ADEs can prevent harm to patients. The Global Trigger Tool, produced by the Institute for Healthcare Improvement (GTT/IHI), is widely used to identify AEs. Recognizing the profile of patients who suffer ADEs can reveal clinical or individual characteristics that predispose to the occurrence of AEs. A cross-sectional study was carried out through a retrospective analysis of 120 medical charts of patients discharged from hospital between October 2020 and April 2021. Patients over 18 years old, with a length of stay of more than 24 h, were included. The list of triggers used was from the medication module of the GTT/IHI, which was adapted for use in the institution. Two primary reviewers and a medical reviewer applied this tool. The primary reviewers independently assessed the randomized charts. A meeting to achieve consensus among the reviewers was held every 2 weeks to validate the identified ADEs; classifications were based on harm severity. Multivariate logistic regression was utilized to assess the variables that predicted the occurrence of ADEs, using the backward stepwise method. A total of 43 ADEs were identified, with a frequency of 36 per 100 admissions (43/120). Of these, five ADEs (12%) were responsible for patients being admitted to hospital. In the case of in-hospital ADEs, there were 42.2 per 1000 patients/day. The clinical manifestation of altered kidney function (16%) and the anatomical drug group of the nervous system (33%) were the most frequent ADEs. The multivariate logistic regression model was significant (×2 = 44.960, P < .001), indicating that factors such as: known drug allergy [odds ratio 5.728; 95% confidence interval (CI): 1.249, 26.274, P = .025]; being clinically hospitalized (odds ratio 7.504; 95% CI: 1.654, 34.037; P = .009); number of medicines used (odds ratio 1.100; 95% CI: 1.054, 1.148; P < .001); and being under the care of internal medicine (odds ratio 3.633; 95% CI: 1.257, 10.511; P = .017) were predictor variables associated with the occurrence of ADEs. A significant percentage of hospitalized patients experienced at least one ADE, with rates surpassing those found in similar studies. The GTT/IHI effectively assessed medication-related harm, emphasizing the need for tailored triggers based on population characteristics. Predictor variables can inform preventive strategies. Overall, the tool facilitated a localized risk assessment of medication use.

RESUMEN

BACKGROUND: One strategy to prevent adverse effects resulting from chemotherapy treatment is to perform physical exercises during treatment. However, there is still no consensus on the best type and intensity of exercise, nor when it should be started. Most studies have been carried out in patients with breast cancer, usually a few weeks after starting chemotherapy, on an outpatient basis 2 to 3 times a week. The main differences in our study are that we carried out physical training in hospitalized patients undergoing a cycle of chemotherapy for cancer treatment and that this training was carried out 5 times a week and was not restricted to a specific type of cancer. OBJECTIVE: We aimed to evaluate the effects of aerobic training on symptoms related to chemotherapy (nausea, vomiting, asthenia, and sensation of weakness), fatigue, mobility, clinical complications, and length of hospital stay of patients during the drug treatment cycle. We also evaluated patient satisfaction with the proposed intervention, the adverse effects of aerobics training, and the cost-effectiveness of this intervention. METHODS: This is a controlled and randomized trial with blinded evaluation that will include 94 hospitalized patients with cancer for 1 or more cycles of chemotherapy. The intervention group will perform aerobic training during a cycle of chemotherapy. The control group will receive a booklet with guidelines for staying active during the hospitalization period. The groups will be compared using a linear mixed model for fatigue, mobility, and chemotherapy-related symptoms before and after the intervention. The length of hospital stay will also be compared between groups using Kaplan-Meier survival analysis. The incidence of complications will be compared using the χ2 test. Cost-effectiveness and cost-utility analyses will be performed for the impact of exercise and quality-adjusted life years with the EQ-5D-3L-21 quality of life trials. The implementation variables (acceptability, suitability, and feasibility) will be evaluated by frequencies. RESULTS: The clinical trial registration was approved in March 2023. Recruitment and data collection for the trial are ongoing, and the results of this study are likely to be published in late 2025. CONCLUSIONS: Chemotherapy has side effects that negatively impact the quality of life of patients with cancer. Aerobic exercise can reduce these side effects in a simple and inexpensive way. The field of work of physical therapists could be expanded to oncology if the intervention works.

RESUMEN

La Quimioterapia Preventiva (QP) es una herramienta vital en la salud pública, utilizada para controlar y eliminar enfermedades infecciosas desatendidas (EID) mediante la administración regular de medicamentos. Este enfoque reduce la incidencia y la propagación de estas enfermedades y mitiga la gravedad de sus secuelas a largo plazo. Al tratar a las poblaciones elegibles, la QP brinda beneficios significativos para la salud, pero también conlleva la responsabilidad ética de garantizar la seguridad de estos medicamentos, adhiriéndose al principio fundamental de "no hacer daño". La seguridad en la administración de medicamentos es crucial para el éxito de cualquier programa de salud pública. La población debe confiar en la seguridad y efectividad de los medicamentos para participar de manera efectiva en estos programas. Esta confianza se logra asegurando que cada etapa del proceso, desde la fabricación de los medicamentos cumpliendo con estrictos estándares de calidad, hasta su envío, gestión en la cadena de suministro, administración y monitoreo de eventos adversos, se realice con la máxima diligencia. Para proporcionar guías prácticas, materiales de capacitación y herramientas de apoyo, la Organización Panamericana de la Salud (OPS) y la Organización Mundial de la Salud (OMS) han desarrollado, en colaboración con socios estratégicos, una serie de directrices, manuales y materiales educativos disponibles en línea. Estos recursos están diseñados para apoyar a los programas nacionales de EID en la planificación, preparación y vigilancia de la administración segura de medicamentos. El documento en cuestión complementa estos recursos, ofreciendo soporte específico para el monitoreo de la seguridad de los medicamentos y el manejo de eventos adversos. A través de respuestas a preguntas frecuentes y mensajes clave, se proporciona una guía esencial para el personal que participa en la administración de medicamentos para EID, así como para la comunidad en general. Este enfoque asegura que todos los involucrados estén informados y preparados para manejar cualquier eventualidad, fortaleciendo así la confianza y la efectividad del programa. En resumen, la Quimioterapia Preventiva es una estrategia fundamental en la lucha contra las EID, y su éxito depende en gran medida de la seguridad y confianza en los medicamentos utilizados. A través de directrices claras, capacitación y monitoreo riguroso, la OPS y la OMS aseguran que estos programas no solo sean efectivos, sino también seguros y confiables para todas las comunidades involucradas.

RESUMEN

AIMS: This systematic review aimed to investigate the occurrence of moderate and severe adverse drug reactions (ADRs) to antimicrobials among hospitalized children. METHODS: The PubMed/Medline, Cochrane Library, Embase, Web of Science, Scopus, Lilacs and CINAHL databases were searched in April 2023 to systematically review the published data describing the characteristics of moderate and severe ADRs to antimicrobials among hospitalized children. The search was carried out without date restrictions, up to the search date (April, 2023). RESULTS: At the end of the selection process, 30 articles met the inclusion criteria. Cutaneous reactions were the primary serious clinical manifestations in most articles (19/30), followed by erythema multiforme (71 cases), Stevens-Johnson syndrome (72 cases), and toxic epidermal necrolysis (22 cases). The main antimicrobials involved in moderate and severe ADRs were penicillins, cephalosporins and sulfonamides. Regarding the primary outcomes, 30% (9/30) of the articles reported deaths, and 46.7% (14/30) of studies reported increased lengths of hospital stay, need for intensive care, and transfer to another hospital. Regarding the main interventions, 10% (3/30) of the articles mentioned greater monitoring, suspension, medication substitution or prescription of specific medications for the symptomatology. CONCLUSIONS: The findings of this review could be used to identify areas for improvement and help health professionals and policymakers develop strategies. In addition, we emphasize the importance of knowing about ADRs so that there is adequate management to avoid undesirable consequences.

RESUMEN

BACKGROUND: There is no gold-standard trigger for detecting drug-induced respiratory disorders, a type of Adverse Drug Event (ADE) with high morbimortality, particularly in older people. OBJECTIVE: To propose and evaluate the performance of triggers for detecting hospitalizations related to drug-induced respiratory disorders in older people. METHODS: A pilot cross-sectional study was conducted with older people (age ≥ 60) admitted to a Brazilian hospital. Electronic chart documentation was screened using ICD-10 codes; Global Trigger Tool (GTT); and drugs potentially associated with respiratory disorders. A chart and medication review were conducted to perform the causality assessment using the instrument developed by the World Health Organization. The performance of triggers was evaluated by the Positive Predictive Value (PPV), with values ≥ 0.20 indicating good performance. RESULTS: Among 221 older people, 72 were eligible. Potential drug-induced dyspnea and/or cough were detected in six older people (6/72), corresponding to a prevalence of 8.3 %. The overall PPV of the triggers was 0.14, with abrupt medication stop (PPV = 1.00), codeine (PPV = 1.00), captopril (PPV = 0.33), and carvedilol (PPV = 0.33) showing good performance. Two triggers were proposed for detecting therapeutic ineffectiveness associated with respiratory disorders: furosemide (PPV = 0.23) and prednisone (PPV = 0.20). CONCLUSION: The triggers enabled the identification that one in 12 hospitalizations was related to drug-induced respiratory. Although good performance was observed in the application of triggers, additional investigations are needed to assess the feasibility of incorporating them into clinical practice for the screening, detection, management, and reporting of these ADEs, which are considered to be underreported and difficult to detect.

RESUMEN

OBJECTIVE: To assess regional and national mortality and years of life lost (YLL) related to adverse drug events in Brazil. METHODS: This is an ecological study in which death records from 2009 to 2018 from the Mortality Information System were analyzed. Codes from the International Classification of Diseases 10th revision (ICD-10) that indicated drugs as the cause of death were identified. The number of deaths and the YLL due to adverse drug events were obtained. Crude, age- and gender-specific, and age-adjusted mortality rates and YLL rates per 100,000 inhabitants were formed by year, age group, gender, and Brazilian Federative Unit. Rate ratios were calculated by comparing rates from 2009 to 2018. A joinpoint regression model was applied for temporal analysis. RESULTS: For the selected ICD-10 codes, a total of 95,231 deaths and 2,843,413 YLL were recorded. Mortality rates from adverse drug events increased by a mean of 2.5% per year, and YLL rates increased by 3.7%. Increases in rates were observed in almost all age groups for both genders. Variations in rates were found between Federative Units, with the highest age-adjusted mortality and YLL rates occurring in the Distrito Federal. CONCLUSIONS: The numbers and rates of deaths and YLL increased during the study period, and variations in rates of deaths and YLL were observed between Brazilian Federative Units. Information on multiple causes of death from death certificates can be useful for quantifying adverse drug events and analyzing them geographically, by age and by gender.

RESUMEN

This systematic review and meta-analysis aimed to verify the association between the genetic variants of adenosine triphosphate (ATP)-binding cassette subfamily B member 1 (ABCB1) and ATP-binding cassette subfamily G member 2 (ABCG2) genes and the presence and severity of gefitinib-associated adverse reactions. We systematically searched PubMed, Virtual Health Library/Bireme, Scopus, Embase, and Web of Science databases for relevant studies published up to February 2024. In total, five studies were included in the review. Additionally, eight genetic variants related to ABCB1 (rs1045642, rs1128503, rs2032582, and rs1025836) and ABCG2 (rs2231142, rs2231137, rs2622604, and 15622C>T) genes were analyzed. Meta-analysis showed a significant association between the ABCB1 gene rs1045642 TT genotype and presence of diarrhea (OR = 5.41, 95% CI: 1.38-21.14, I2 = 0%), the ABCB1 gene rs1128503 TT genotype and CT + TT group and the presence of skin rash (OR = 4.37, 95% CI: 1.51-12.61, I2 = 0% and OR = 6.99, 95%CI: 1.61-30.30, I2= 0%, respectively), and the ABCG2 gene rs2231142 CC genotype and presence of diarrhea (OR = 3.87, 95% CI: 1.53-9.84, I2 = 39%). No ABCB1 or ABCG2 genes were positively associated with the severity of adverse reactions associated with gefitinib. In conclusion, this study showed that ABCB1 and ABCG2 variants are likely to exhibit clinical implications in predicting the presence of adverse reactions to gefitinib.

RESUMEN

Contexto: O coronavírus da Síndrome Respiratória Aguda Grave (SARS-CoV-2) espalhou-se rapidamente em todo o mundo, a partir de dezembro de 2019. A vacinação tornou-se prioridade para a prevenção da doença, mas junto surgiu o temor de eventos adversos. Objetivo: Avaliar as evidências de possíveis eventos adversos das vacinas para COVID-19 em crianças e adolescentes. Material e Métodos: Trata-se de sinopse baseada em evidências. Procedeu-se à busca por estudos que associavam as vacinas para COVID-19 a eventos adversos a elas relacionados em três bases de dados: PubMed (1966-2024), Portal BVS (1982-2024) e Embase (1974-2024) e também no metabuscador de evidências TRIP DATABASE (2024). Foram utilizados os termos "COVID-19 Vaccines/adverse effects "[Mesh] Filters: Child: birth-18 years". Dois pesquisadores independentemente extraíram os dados e avaliaram a qualidade dos estudos para a síntese. O desfecho de análise envolveu a efetividade das vacinas para COVID-19 em crianças e adolescentes e a ocorrência de eventos adversos. Resultados: Foram encontradas 552 referências, seis estudos (3 revisões sistemáticas e 3 ensaios clínicos) foram incluídos (n = 13.642.718 participantes). Discussão: Há um número bastante razoável de estudos e amostragem sobre a vacinação para a COVID-19 em crianças e adolescentes. Esses estudos mostram efetividade e segurança das vacinas, sendo a ocorrência de eventos adversos mais associada a efeitos locais leves a moderados e um risco muito baixo de eventos adversos sistêmicos graves. Conclusões: Há evidência de efetividade das vacinas e baixo risco de complicações a elas associado, considerando-se que o risco-benefício justifica sua utilização em crianças e adolescentes nesse momento. Termos DeCS: Prática clínica baseada em evidências, vacina, COVID-19, eventos adversos, revisão.

RESUMEN

OBJECTIVES: Underreporting of adverse drug reactions (ADRs) limits and delays the detection of signs. The aim of this systematic review with meta-analyses was to synthesize the evidence of educational interventions (EIs) efficacy in health professionals to increase ADR reporting, attitudes, and knowledge of pharmacovigilance. EVIDENCE ACQUISITION: A systematic literature review was carried out to identify randomized clinical trials evaluating the efficacy of EI in pharmacovigilance in health professionals to improve ADR reports, knowledge, and attitude toward pharmacovigilance. ADR reports were pooled by calculating Odds Ratio (OR) with a 95% confidence interval (95%CI), while pharmacovigilance knowledge and attitude were pooled by calculating a mean difference (MD) with 95%CI. In addition, the subanalysis was performed by EI type. Meta-analysis was performed with RevMan 5.4 software. PROSPERO registry CRD42021254270. RESULTS: Eight hundred seventy-five articles were identified as potentially relevant, and 11 were included in the systematic review. Metanalysis showed that EI increased ADR reporting in comparison with control group (OR = 4.74, [95%CI, 2.46 to 9.12], I2 = 93%, 5 studies). In subgroup analysis, the workshops (OR = 6.26, [95%CI, 4.03 to 9.73], I2 = 57%, 3 studies) increased ADR reporting more than telephone-based interventions (OR = 2.59, [95%CI, 0.77 to 8.73], I2 = 29%, 2 studies) or combined interventions (OR = 5.14, [95%CI, 0.97 to 27.26], I2 = 93%, 3 studies). No difference was observed in pharmacovigilance knowledge. However, the subanalysis revealed that workshops increase pharmacovigilance knowledge (SMD = 1.85 [95%CI, 1.44 to 2.27], 1 study). Only one study evaluated ADR reporting attitude among participants and showed a positive effect after the intervention. CONCLUSION: EI improves ADR reports and increases pharmacovigilance knowledge. Workshops are the most effective EI to increase ADR reporting.

RESUMEN

PURPOSE: Postpartum hemorrhage (PPH) is a leading cause of maternal mortality worldwide. Although several studies on the prophylactic use of tranexamic acid (TXA) in parturients undergoing Cesarean delivery have been published, conflicting results raise questions regarding its use. Thus, we aimed to investigate the safety and efficacy of PPH prophylaxis with TXA. SOURCE: We searched PubMed®, Embase, Cochrane Central, and ClinicalTrials.gov for randomized controlled trials (RCTs) comparing prophylactic TXA with placebo or no treatment in parturients undergoing Cesarean delivery. Our main outcomes were PPH, any blood transfusion, need for additional uterotonics, and adverse events. We performed a trial sequential analysis (TSA) of all outcomes to investigate the reliability and conclusiveness of findings. PRINCIPAL FINDINGS: We included 38 RCTs including 22,940 parturients, 11,535 (50%) of whom were randomized to receive prophylactic TXA. Patients treated with TXA had significantly fewer cases of PPH (risk ratio [RR], 0.51; 95% confidence interval [CI], 0.38 to 0.69; P < 0.001); less blood transfusion (RR, 0.43; 95% CI, 0.30 to 0.61; P < 0.001), and less use of additional uterotonics (RR, 0.52; 95% CI, 0.40 to 0.68; P < 0.001). No significant differences were found between the groups in terms of adverse effects and thromboembolic events. CONCLUSION: Prophylactic TXA administration for parturients undergoing Cesarean delivery significantly reduced blood loss, without increasing adverse events, supporting its use as a safe and effective strategy for reducing PPH in this population. STUDY REGISTRATION: PROSPERO (CRD42023422188); first submitted 27 April 2023.

RéSUMé: OBJECTIF: L'hémorragie du post-partum (HPP) est l'une des principales causes de mortalité maternelle dans le monde. Bien que plusieurs études sur l'utilisation prophylactique d'acide tranexamique (TXA) chez les personnes parturientes ayant accouché par césarienne aient été publiées, des résultats contradictoires soulèvent des questions quant à son utilisation. Ainsi, nous avons cherché à étudier l'innocuité et l'efficacité de la prophylaxie à base de TXA pour l'HPP. SOURCES: Nous avons fait une recherche sur PubMed®, Embase, Cochrane Central et ClinicalTrials.gov pour en tirer les études randomisées contrôlées (ERC) comparant le TXA prophylactique à un placebo ou à l'absence de traitement chez les personnes parturientes accouchant par césarienne. Nos principaux critères d'évaluation étaient l'HPP, toute transfusion sanguine, la nécessité d'un utérotonique supplémentaire et les événements indésirables. Nous avons effectué une analyse séquentielle des études pour tous les résultats afin d'examiner la fiabilité et le caractère concluant des conclusions. CONSTATATIONS PRINCIPALES: Nous avons inclus 38 ERC comprenant 22 940 personnes parturientes, dont 11 535 (50 %) ont été randomisées pour recevoir du TXA prophylactique. La patientèle traitée par TXA présentait significativement moins de cas d'HPP (risque relatif [RR], 0,51; intervalle de confiance [IC] à 95 %, 0,38 à 0,69; P < 0,001); moins de transfusion sanguine (RR, 0,43; IC 95 %, 0,30 à 0,61; P < 0,001) et moins d'utilisation d'utérotoniques supplémentaires (RR, 0,52; IC 95 %, 0,40 à 0,68; P < 0,001). Aucune différence significative n'a été constatée entre les groupes en termes d'effets indésirables et d'événements thromboemboliques. CONCLUSION: L'administration prophylactique de TXA pour les personnes parturientes accouchant par césarienne a considérablement réduit les pertes de sang sans augmenter les événements indésirables, ce qui soutient son utilisation comme stratégie sécuritaire et efficace pour réduire l'HPP dans cette population. ENREGISTREMENT DE L'éTUDE: PROSPERO (CRD42023422188); première soumission le 27 avril 2023.

RESUMEN

The widespread production and use of plastics have resulted in accumulation of plastic debris in the environment, gradually breaking down into smaller particles over time. Nano-plastics (NPs) and microplastics (MPs), defined as particles smaller than 100 nanometers and 5 millimeters, respectively, raise concerns due to their ability to enter the human body through various pathways including ingestion, inhalation, and skin contact. Various investigators demonstrated that these particles may produce physical and chemical damage to human cells, tissues, and organs, disrupting cellular processes, triggering inflammation and oxidative stress, and impacting hormone and neurotransmitter balance. In addition, micro- and nano-plastics (MNPLs) may carry toxic chemicals and pathogens, exacerbating adverse effects on human health. The magnitude and nature of these effects are not yet fully understood, requiring further research for a comprehensive risk assessment. Nevertheless, evidence available suggests that accumulation of these particles in the environment and potential human uptake are causes for concern. Urgent measures to reduce plastic pollution and limit human exposure to MNPLs are necessary to safeguard human health and the environment. In this review, current knowledge regarding the influence of MNPLs on human health is summarized, including toxicity mechanisms, exposure pathways, and health outcomes across multiple organs. The critical need for additional research is also emphasized to comprehensively assess potential risks posed by degradation of MNPLs on human health and inform strategies for addressing this emerging environmental health challenge. Finally, new research directions are proposed including evaluation of gene regulation associated with MNPLs exposure.
