Folic acid supplementation during pregnancy and postpartum depressive symptoms.

OBJECTIVE: To verify whether folic acid supplementation during pregnancy is associated with the occurrence of maternal depressive symptoms at three months postpartum, in the 2015 Pelotas Birth Cohort. METHODS: This study included 4,046 women, who were classified into three groups: did not use folic acid supplementation during pregnancy; used during only one trimester of pregnancy; and used for two or three trimesters. Depressive symptoms were assessed at three months postpartum using the Edinburgh Postnatal Depression Scale (EPDS), at cutoff points ≥ 10 (mild symptoms) and ≥ 13 (moderate to severe intensity). RESULTS: The overall prevalence of mild symptoms was of 20.2% (95%CI 19.0-21.5), and moderate and severe was 11% (95%CI 10.0-12.0). The prevalence of EPDS ≥ 10 was of 26.8% (95%CI 24.0-29.5) among women who did not use folic acid and 18.1% for both those who used it during one trimester of pregnancy (95%CI 16.1-20.1) and those who used it for two or three trimesters (95%CI 16.0-20.2). The prevalence of EPDS ≥ 13 was of 15.7% (95%CI 13.5-17.9) in those who did not use folic acid, 9.1% (95%CI 7.5-10.6) in those who used it for one trimester, and 9.4% (95%CI 7.8-11.0) in those who used it for two or three trimesters. In the adjusted analyses, there was no statistically significant association between the use of folic acid during pregnancy and the occurrence of depressive symptoms at three months postpartum. CONCLUSION: There was no association between folic acid supplementation during pregnancy and postpartum depression at three months.

Iron salt supplementation during gestation and gestational diabetes mellitus.

OBJETIVE: To evaluate the association between the use of iron salts during the first two trimesters of gestation in non-anemic women and the development of gestational diabetes mellitus. METHODS: The study used maternal data from the 2015 Pelotas Birth Cohort. All non-anemic women at the 24th week of gestation (n = 2,463) were eligible for this study. Gestational diabetes mellitus was self-reported by women. Crude and adjusted logistic regression were performed considering level of significance = 0.05. RESULTS: Among the women studied, 69.7% were exposed to prophylactic iron supplementation in the first two trimesters of gestation. The prevalence of gestational diabetes mellitus among those exposed was 8.7% (95%CI: 7.4­10.1) and 9.3% (95%CI: 7.4­11.6) among those who were not exposed. Iron supplementation was not associated with increased risk of gestational diabetes mellitus in crude (OR = 0.9; 95%CI: 0,7­1,3) and adjusted analysis (OR = 1.1; 95%CI :0,8­1,6). CONCLUSIONS: The results suggest that routine iron use in non-anemic pregnant women does not increase the risk of developing gestational diabetes. This evidence supports the existing national and international guidelines, in which prophylactic iron supplementation is recommended for all pregnant women as soon as they initiate antenatal care in order to prevent iron deficiency anemia.

Self-medication in children aged 0-12 years in Brazil: a population-based study.

OBJETIVE: Studies have shown that the practice of self-medicating children occurs worldwide and is independent of the country's economic level, medication policies, or access to health services. This study aimed to estimate and characterize the prevalence of self-medication in the Brazilian population of children aged up to 12 years. METHODS: We analyzed the data of 7528 children aged up to 12 years whose primary caregivers responded to the National Survey on Access, Use and Promotion of Rational Use of Medicines in Brazil (PNAUM), a cross-sectional population-based study conducted in 245 Brazilian municipalities. The prevalence of self-medication was defined as the use of at least one medication without a doctor's or dentist's indication 15 days before the interview. RESULTS: The prevalence of self-medication was 22.2% and was more frequent in older children belonging to poorer families and without health insurance. The acute conditions for which there was a higher frequency of self-medication were pain, fever, and cold/allergic rhinitis. Analgesics/antipyretics stood out among the most used medications for self-medication. CONCLUSIONS: The prevalence of self-medication to treat acute conditions was high in Brazilian children sampled in PNAUM, emphasizing the management of common symptoms such as pain, fever, and cold/allergic rhinitis in this age group. These findings reinforce the need for educational actions aimed at parents and caregivers.

Adherence and Quality of Life in Non-Valvular Atrial Fibrillation With Direct Oral Anticoagulants Versus Vitamin K Antagonists: A Systematic Review

Abstract Background Direct anticoagulants (DOACs) and vitamin K antagonists (VKAs) differ in pharmacokinetic characteristics, intensity of required laboratory monitoring, and costs. These differences could affect patients' adherence to treatment and quality of life (QoL). Objective To assess whether patients with non-valvular atrial fibrillation (AF) using DOACs have better treatment adherence and QoL when compared to patients using VKAs. Methods We conducted a systematic review in Medline, Embase, LILACS, SciELO, CINAHL, and Cochrane Central, until June 9, 2021. We included studies that estimated and compared treatment adherence and QoL between DOACs and VKAs in adults with non-valvular AF. The methodological quality of the studies was assessed using the Joanna Briggs Institute (JBI) tools. The protocol was registered in the PROSPERO (CRD 42020165238). Results Sixteen studies, including 122,458 patients with non-valvular AF, evaluated adherence, and eleven studies, including 5,687 patients, assessed QoL. A variety of methods was used to measure adherence. Eleven studies showed no difference in adherence between DOACs and VKAs, while three studies favored VKAs over DOACs and two studies favored DOACs over VKAs. QoL was measured by specific (n = 3) or generic questionnaires (n = 8); results favored DOACs over VKAs in four studies, while in the other seven studies the results showed no difference between the groups. Meta-analyses were not performed due to high methodological heterogeneity among studies. Conclusions Available evidence regarding treatment adherence and QoL with DOACs and VKAs is characterized by methodological heterogeneity and conflicting findings.

RESUMO Objetivo: Estudos têm mostrado que a prática de automedicar crianças ocorre mundialmente e independe do nível econômico do país, das políticas de medicamentos ou do acesso aos serviços de saúde. O objetivo deste estudo foi estimar e caracterizar a prevalência de uso de medicamentos por automedicação na população brasileira de crianças de zero a 12 anos de idade. Métodos: Foram analisadas informações de 7.528 crianças de zero a 12 anos cujo cuidador principal respondeu à Pesquisa Nacional sobre Acesso, Utilização e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM), estudo transversal de base populacional realizado em 245 municípios brasileiros. A prevalência de automedicação foi definida como o uso de pelo menos um medicamento sem indicação de médico ou dentista nos 15 dias anteriores à entrevista. Resultados: A prevalência de automedicação foi de 22,2% e foi mais frequente nas crianças mais velhas e pertencentes a famílias mais pobres e sem plano de saúde. As condições agudas para as quais houve maior frequência de automedicação foram dor, febre, resfriado e rinite alérgica. Analgésicos/antipiréticos destacaram-se entre os medicamentos mais utilizados por automedicação. Conclusões: A prevalência de automedicação no manejo de condições agudas foi elevada nas crianças brasileiras amostradas na PNAUM, com destaque para o manejo de sintomas comuns nessa faixa etária, como dor, febre, resfriado e rinite alérgica. Esses achados reforçam a necessidade de ações educativas voltadas aos pais e cuidadores.

RESUMO OBJETIVO Verificar se a suplementação de ácido fólico durante a gestação está associada com a ocorrência de sintomas depressivos maternos aos três meses pós-parto, na Coorte de Nascimentos de Pelotas de 2015. MÉTODOS Este estudo incluiu 4.046 mulheres, que foram classificadas em três grupos: sem suplementação de ácido fólico na gestação; uso durante apenas um trimestre da gestação;e uso durante dois ou três trimestres. Os sintomas depressivos foram avaliados aos três meses pós-parto, através da Escala de Depressão Pós-Natal de Edimburgo (EPDS), nos pontos de corte ≥ 10 (sintomas leves) e ≥ 13 (intensidade moderada a grave). RESULTADOS A prevalência geral de sintomas leves foi de 20,2% (IC95% 19,0-21,5),e moderados e graves de 11% (IC95% 10,0-12,0). Entre as mulheres que não fizeram uso de ácido fólico, a prevalência de EPDS ≥ 10 foi de 26,8% (IC95% 24,0-29,5) e 18,1% tanto entre as que utilizaram durante um trimestre da gestação (IC95% 16,1-20,1), quanto entre as que utilizaram por dois ou três trimestres (IC95% 16,0-20,2). Já a prevalência de EPDS ≥ 13 foi 15,7% (IC95% 13,5-17,9) entre as que não utilizaram ácido fólico, 9,1% (IC95% 7,5-10,6) entre as que utilizaram durante um trimestre e 9,4% (IC95% 7,8-11,0) entre as que utilizaram por dois ou três trimestres. Nas análises ajustadas, não houve associação estatisticamente significativa entre o uso de ácido fólico na gestação e a ocorrência de sintomas depressivos aos três meses pós-parto. CONCLUSÃO Não se observou associação entre a suplementação de ácido fólico na gestação e depressão pós-parto aos três meses.

Iron Salts, High Levels of Hemoglobin and Ferritin in Pregnancy, and Development of Gestational Diabetes: A Systematic Review / Sais de ferro, níveis elevados de hemoglobina e ferritina na gravidez e o desenvolvimento de diabetes gestacional: Uma revisão sistemática

Abstract Objective The aim of this study was to systematically review literature on the use of iron supplements (not including iron derived from diet), increased levels of hemoglobin and/or ferritin, and the risk of developing gestational diabetes mellitus (GDM). Data source The following databases were searched, from the study's inception to April 2021: PUBMED, Cochrane, Web of Science, Scopus, Embase, Cinahl and Lilacs. Selection of studies A total of 6,956 titles and abstracts were reviewed, 9 of which met the final inclusion criteria, with 7,560 women in total. Data collection Data extraction was performed by two independent reviewers and disagreements were resolved by a third researcher. Data synthesis Methodological quality in controlled trials were assessed according to the Cochrane Collaboration tools (ROB-2 and ROBINS-1) and for the observational studies, the National Institutes of Health's (NIH) quality assessment tool was used. Among the 5 observational studies, women with a higher hemoglobin or ferritin level were more likely to develop GDM when compared with those with lower levels of these parameters. Among the 3 randomized clinical trials, none found a significant difference in the incidence of GDM among women in the intervention and control groups. However, we identified many risks of bias and great methodological differences among them. Conclusion Based on the studies included in this review, and due to the important methodological problems pointed out, more studies of good methodological quality are needed to better establish the association between iron supplementation and GDM.

Benzodiazepines utilization in Brazilian older adults: a population-based study.

OBJECTIVE: To evaluate the utilization of benzodiazepines (BZD) in Brazilian older adults, based on the Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM - National Survey of Access, Use and Promotion of Rational Use of Medicines). METHODS: The PNAUM is a cross-sectional study conducted between 2013 and 2014, representing the Brazilian urban population. In the present study, we included 60 years or older (n = 9,019) individuals. We calculated the prevalence of BZD utilization in the 15 days prior to survey data collection according to independent variables, using a hierarchical Poisson regression model. A semistructured interview performed empirical data collection (household interview). RESULTS: The prevalence of BZD utilization in the older adults was 9.3% (95%CI: 8.3-10.4). After adjustments, BZD utilization was associated with female sex (PR = 1.88; 95%CI: 1.52-2.32), depression (PR = 5.31; 95%CI: 4.41-6, 38), multimorbidity (PR = 1.44; 95%CI: 1.20-1.73), emergency room visit or hospitalization in the last 12 months (PR = 1.42; 95%CI: 1.18-1.70 ), polypharmacy (PR = 1.26; 95%CI: 1.01-1.57) and poor or very poor self-rated health (PR = 4.16; 95%CI: 2.10-8.22). Utilization was lower in the North region (PR = 0.18; 95%CI: 0.13-0.27) and in individuals who reported abusive alcohol consumption in the last month (PR = 0.42; 95%CI: 0.19-0.94). CONCLUSION: Despite contraindications, results showed a high prevalence of BZD utilization in older adults, particularly in those with depression, and wide regional and sex differences.

Prevalence of chronic respiratory diseases and medication use among children and adolescents in Brazil - a population based cross-sectional study / Prevalência de doenças respiratórias crônicas e uso de medicamentos entre crianças e adolescentes no Brasil - um estudo transversal de base populacional

Abstract Objectives: to describe the prevalence of chronic respiratory diseases and their pharmacological management in children and adolescents in Brazil. Methods: data from the Pesquisa Nacional de Acesso, Uso e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM)(National Access Survey, Use and Promotion of Rational Use of Medicines in Brazil),a population-based cross-sectional study, were analyzed. Household surveys were conducted between September 2013 and February 2014. We included the population under 20 years of age with chronic respiratory diseases. Prevalence of disease, indication of pharmacological treatment, and their use were assessed. Results: the prevalence of chronic respiratory diseases in children aged less than 6 years old was 6.1% (CI95%= 5.0-7.4), 4.7% (CI95%= 3.4-6.4) in those 6-12 years, and 3.9% (CI95%= 2.8-5.4) in children 13 years and older. Children under 6 showed a higher prevalence of pharmacological treatment indication (74.6%; CI95%= 66.0-81.7), as well as medication use (72.6%; CI95%= 62.8-80.7). Of those using inhalers, 56.6% reported using it with a spacer. The most frequent pharmacologic classes reported were short-acting β2 agonists (19.0%), followed by antihistamines (17.2%). Conclusion: children and adolescents who report chronic respiratory diseases living in urban areas in Brazil seem to be undertreated for their chronic conditions. Pharmacological treatment, even if indicated, was not used, an important finding for decision-making in this population.

Resumo Objetivos: descrever a prevalência de doenças respiratórias crônicas e seu manejo farmacológico em crianças e adolescentes no Brasil. Métodos: foram analisados os dados da Pesquisa Nacional de Acesso, Uso e Promoção do Uso Racional de Medicamentos no Brasil (PNAUM), um estudo transversal de base populacional. As pesquisas domiciliares foram realizadas entre setembro de 2013 e fevereiro de 2014. Incluímos a população com menos de 20 anos de idade com doenças respiratórias crônicas. Foi avaliada a prevalência de doença, indicação de tratamento farmacológico e seu uso. Resultados: a prevalência de doenças respiratórias crônicas em menores de 6 anos foi de 6,1% (IC95%= 5,0-7,4), 4,7% (IC95%= 3,4-6,4) naqueles 6-12 anos e 3,9% (IC95%= 2,8-5,4) em crianças com 13 anos ou mais. Crianças menores de 6 anos apresentaram uma maior prevalência de indicação de tratamento farmacológico (74,6%; IC95%= 66,0-81,7), assim como uso de medicamentos (72,6%; IC95%= 62,8-80,7). Dos usuários de inaladores, 56,6% relataram o uso com espaçador. As classes farmacológicas mais frequentemente relatadas foram β2 agonistas de curta ação (19,0%), seguidos por anti-histamínicos (17,2%). Conclusão: crianças e adolescentes que relatam doenças respiratórias crônicas residentes em áreas urbanas no Brasil parecem ser subtratados para suas condições crônicas. O tratamento farmacológico, mesmo quando indicado, não foi utilizado em sua totalidade, um achado importante para a tomada de decisão nessa população.

RESUMO OBJETIVO Avaliar a utilização de benzodiazepínicos (BZD) em idosos brasileiros,a partir de dados da Pesquisa Nacional de Acesso, Utilização e Promoção do Uso Racional de Medicamentos (PNAUM). MÉTODOS A PNAUM é um estudo transversal, conduzido entre 2013 e 2014, com representatividade da população urbana brasileira. No presente estudo, foram incluídos indivíduos com 60 anos ou mais (n = 9.019). Foi calculada a prevalência de utilização de BZD nos 15 dias anteriores à coleta dos dados da pesquisa, geral e segundo as variáveis independentes, por meio de análise bruta e ajustada, utilizando modelo hierárquico de regressão de Poisson. A coleta de dados foi realizada por meio de entrevista domiciliar. RESULTADOS A prevalência de utilização de BZD em idosos foi de 9,3% (IC95%: 8,3-10,4). Após análise ajustada, foram associados à maior utilização de BZD: sexo feminino (RP = 1,88; IC95%: 1,52-2,32), depressão (RP = 5,31; IC95%: 4,41-6,38), multimorbidade (RP = 1,44; IC95%: 1,20-1,73), visita à emergência ou internação hospitalar nos últimos 12 meses (RP = 1,42; IC95%: 1,18-1,70), polifarmácia (RP = 1,26; IC95%: 1,01-1,57) e autopercepção de saúde ruim ou muito ruim (RP = 4,16; IC95%: 2,10-8,22). A utilização foi menor na região Norte (RP = 0,18; IC95%: 0,13-0,27) e em indivíduos que relataram consumo abusivo de álcool no último mês (RP = 0,42; IC95%: 0,19-0,94). CONCLUSÃO Apesar das recomendações contrárias ao uso, os resultados demonstraram elevada prevalência de utilização de BZD em idosos, particularmente naqueles que apresentam depressão, além de amplas diferenças em relação às regiões do país e ao sexo do indivíduo.

Breastfeeding and drug use: what is the orientation found in drug package inserts of contraceptives and anti-infective agents? / Amamentação e utilização de medicamentos: qual a orientação presente nas bulas de anticoncepcionais e anti-infecciosos?

This article aims to evaluate the conformity between drug package inserts (DPIs) and evidence-based bibliographic sources regarding the presence of contraindications to the use of contraceptives and anti-infective agents during breastfeeding. Contraceptive and anti-infectives were selected, according to ATC, with the updated record in the ANVISA and present in the bibliographic sources Breastfeeding and Use of Medicines and Other Substances, Medications and Mother's Milk, LactMed®, Micromedex® and UpToDate®. Information was extracted from the DPI "Contraindications" and "Warnings and precautions" sections and compared with the information in the bibliographic sources. The contraindication of the drug during breastfeeding was evaluated. Contraindications were found in the DPIs of five (55.5%) of the nine contraceptives. The contraindication percentage ranged from 0 to 55.5% among the bibliographic sources, depending on the source. The percentage was 46.3% in the DPIs, ranging from 0 to 12.9% in the bibliographic sources for anti-infectives. There is an agreement between the DPIs and the bibliographic sources regarding contraceptives; regarding anti-infectives, the DPIs are more often contraindicated for use during breastfeeding.

Abstract This article aims to evaluate the conformity between drug package inserts (DPIs) and evidence-based bibliographic sources regarding the presence of contraindications to the use of contraceptives and anti-infective agents during breastfeeding. Contraceptive and anti-infectives were selected, according to ATC, with the updated record in the ANVISA and present in the bibliographic sources Breastfeeding and Use of Medicines and Other Substances, Medications and Mother's Milk, LactMed®, Micromedex® and UpToDate®. Information was extracted from the DPI "Contraindications" and "Warnings and precautions" sections and compared with the information in the bibliographic sources. The contraindication of the drug during breastfeeding was evaluated. Contraindications were found in the DPIs of five (55.5%) of the nine contraceptives. The contraindication percentage ranged from 0 to 55.5% among the bibliographic sources, depending on the source. The percentage was 46.3% in the DPIs, ranging from 0 to 12.9% in the bibliographic sources for anti-infectives. There is an agreement between the DPIs and the bibliographic sources regarding contraceptives; regarding anti-infectives, the DPIs are more often contraindicated for use during breastfeeding.

Use of drugs for gastrointestinal disorders: evidence from National Survey on Access, Use and Promotion of Rational Use of Medicines.

Objective To estimate the prevalence of use of drugs to treat gastrointestinal disorders, according to demographic, socioeconomic, and health characteristics of the Brazilian population. Methods This is a population-based survey that interviewed individuals residing in cities of the five regions in Brazil. The study sample was composed of 32,348 individuals aged 20 or more years. The profile of use of drugs for gastrointestinal disorders was evaluated considering the variables sex, age, healthcare plan, region, and number of chronic diseases. We also analyzed the frequency of individuals who declared using other drugs, besides those already employed for treatment of gastrointestinal disorders. Additionally, the estimated frequencies of the drug classes used were determined. Results The prevalence of use of drugs for gastrointestinal disorders in Brazil was 6.9% (95% confidence interval - 6.4-7.6), higher in females, among persons aged over 60 years, in those who had a private healthcare insurance, and presented with two or more chronic diseases. It was noted that 42.9% of the aged who used drugs for gastrointestinal disorders were also on polypharmacy. As to the classes of drugs, 82% corresponded to drugs for the food tract and metabolism, particularly proton pumps inhibitors. Conclusion The use of drugs for treatment of gastrointestinal disorders was significant among women and elderly. In this age group, consumption may be linked to gastric protection due to polypharmacy. This study is an unprecedented opportunity to observe the self-reported consumption profile of these drugs in Brazil and, therefore, could subsidize strategies to promote their rational use.

Nationwide use of psychotropic drugs for treatment of self-reported depression in the Brazilian urban adult population.

OBJECTIVE: Antidepressant use is increasing worldwide, but national data on psychotropic drug use by depressed patients in Brazil is lacking. METHODOLOGY: Between 2013 and 2014, a representative sample of urban adult individuals were asked if they had a diagnosis of chronic disease, had a medical indication for drug treatment, and were taking chronic medications at the time for each reported diagnosis. We analyzed the frequencies of reported depression and the medications related to this disease. RESULTS: Overall, 6.1% of respondents reported depression. The prevalence increased with age - 9.5% among the elders - was higher among women (8.9%) and in the south of the country (8.9%). As a single disease, the prevalence of depression was higher among young people (17.6%). Among those with multimorbidity, the prevalence of depression rose to 25.7%. Of those who reported depression, 81.3% had medical indication for treatment and 90.3% were under treatment - this proportion was lower among young people (84.5%) and those living in the poorest region (78.6%). Antidepressants accounted for 47.2% of psychotropic drugs taken by respondents with depression, with regional differences - only 30% used antidepressants in the North. Polypharmacy was reported by 22% of those with depression and other chronic diseases. CONCLUSION: Depression in Brazil, is common among young adults as a single chronic disease and highly prevalent among people with chronic multimorbidity, especially the young. The treatment gap was larger among young people and in the less developed regions of the country.

Epidemiology and burden of chronic respiratory diseases in Brazil from 1990 to 2017: analysis for the Global Burden of Disease 2017 Study.

INTRODUCTION: In Brazil, little is known about the trends of chronic respiratory diseases, which was estimated as the third leading cause of deaths in 2017 worldwide. METHODS: We analyzed Global Burden of Disease (GBD) 2017 estimates for prevalence, incidence, mortality, disability-adjusted life years (DALY), a summary measure of years of life lost (YLLs) and years lived with disability (YLDs), and risk factors attributable to chronic respiratory diseases in Brazil from 1990 to 2017. RESULTS: The overall estimates have decreased for all ages and both sexes, and for age-standardized rates. For age-adjusted prevalence, there was a 21% reduction, and nearly 16% reduction for incidence. There was a 42% reduction in mortality for both sexes, though the rate of deaths for men was 30% greater than the rate in women. The increase in the number of DALY was essentially due to the population growth and population ageing. We observed a 34% increase in the absolute number of DALY in Brazil over the study period. The majority of the DALY rates were due to Chronic Obstructive Pulmonary Disease (COPD). For all ages and both sexes, smoking was the main attributable risk factor. CONCLUSION: In Brazil, although mortality, prevalence and incidence for chronic respiratory diseases have decreased over the years, attention should be taken to the DALYs increase. Smoking remained as the main risk factor, despite the significant decrease of tobacco use, reinforcing the need for maintenance of policies and programs directed at its cessation.

Breastfeeding and risk classification of medications used during hospitalization for delivery: 2015 Pelotas Birth Cohort. / Classificação de risco dos medicamentos usados na internação para o parto na amamentação: coorte de nascimentos de Pelotas/2015.

OBJECTIVE: To classify the drugs used during childbirth in relation to risks in breastfeeding, by using different sources of information and determining their disagreements. METHODS: Cross-sectional study, within the 2015 Pelotas Birth Cohort. Information about the use of drugs was collected, classified and compared regarding risk according to: 1) Brazil Ministry of Health Manual (MS), 2) World Organization (WHO), 3) Newton and Hale's classification and 4) American Academy of Pediatrics (AAP). RESULTS: A total of 1,409 mothers participated, and they had used 14,673 medicines, with 143 different drugs, of which 28 showed discordant classification with regard to breastfeeding risk. These 28 drugs included the following: morphine (64%), classified by AAP and WHO as compatible and as judicious use use by MS and Newton and Hale; hyoscine (23%), classified as judicious use by MS and compatible (A) by AAP; and metoclopramide (18%), classified as compatible by MS, of effects unknown (D) by AAP, and should be avoided according to WHO. Of the total drugs, 49.7% were classified as compatible during breastfeeding. Almost all women used oxytocin (97.4%), followed by lidocaine (75%), ketoprofen (69%), cephalothin (66%) and diclofenac (65%), which were classified as compatible. CONCLUSION: There was extensive use of drugs by mothers in labor during admission, most of the drugs being classified at the same risk and almost half classified as compatible with breastfeeding. However, there was disagreement between the sources for 19.6% of the drugs analyzed, which could endanger the infant's health or leave doubts about the use of the drug or breastfeeding.

Off-label use of drugs by age in Brazilian children: a population study. / Uso off-label de medicamentos segundo a idade em crianças brasileiras: um estudo populacional.

OBJECTIVE: To estimate the prevalence of off-label drug use by age in children 12 years old and younger in Brazil. METHOD: Population-based cross-sectional study (National Survey on Access, Use and Promotion of Rational Use of Medicines - PNAUM), including 7,528 children aged 12 years or younger. Face-to-face interviews were used to collect the data in the domiciles. The age-related off-label classification was carried out using the electronic medication compendium of National Agency of Sanitary Surveillance (ANVISA). Sociodemographic characteristics, presence of chronic disease, use of health services and characteristics of the informant were collected. Data were expressed by relative frequencies and 95% confidence intervals. Pearson's chi-square test was used to evaluate the statistical significance of the differences between the groups, with a significance level of 5%. Main outcome measure was the prevalence of off-label use. RESULTS: The prevalence of off-label use by age was 18.7% (95%CI 16.4 - 21.3). Children younger than 2 years old presented the highest prevalence of off-label use. The most frequently used off-label drugs by age were amoxicillin, nimesulide and the combination of phenylephrine and brompheniramine. CONCLUSION: The off-label use of drugs by age is common in the Brazilian pediatric population, especially among children under two years old.

RESUMO: Introdução: No Brasil, pouco se sabe sobre as tendências das doenças respiratórias crônicas, que foram estimadas como a terceira principal causa de mortes em 2017 em todo o mundo. Métodos: Analisamos as estimativas do Global Burden of Disease (GBD) 2017 para prevalência, incidência, mortalidade, anos de vida ajustados por incapacidade (DALY), uma medida resumida de anos de vida perdidos (YLL) e anos vividos com deficiência (YLD), e fatores de risco atribuíveis a doenças respiratórias crônicas no Brasil, de 1990 a 2017. Resultados: As estimativas gerais diminuíram para todas as idades e ambos os sexos, assim como para as taxas padronizadas por idade. Para a prevalência ajustada pela idade, houve uma redução de 21% e, aproximadamente, 16% para a incidência. Houve uma redução de 42% na mortalidade para ambos os sexos, embora a taxa de mortes para homens tenha sido 30% maior do que a taxa para mulheres. O aumento no número de DALY deveu-se ao crescimento e envelhecimento da população. Observamos um aumento de 34% no número absoluto de DALYs no Brasil durante o período do estudo. A maioria das taxas de DALY foi devido a Doença Pulmonar Obstrutiva Crônica (DPOC). Para todas as idades e ambos os sexos, tabagismo foi o principal fator de risco atribuível. Conclusão: No Brasil, embora a mortalidade, a prevalência e a incidência de doenças respiratórias crônicas tenham diminuído ao longo dos anos, maior atenção deve ser dada ao aumento dos DALYs. O tabagismo permaneceu como principal fator de risco, apesar da redução significativa do seu uso, reforçando a necessidade de manutenção de políticas e programas direcionados à sua cessação.
