Prevalence of vitamin A deficiency in women of childbearing age in Brazil: a systematic review and meta-analysis.

Vitamin A is an essential micronutrient, especially during pregnancy. We aimed to assess the prevalence of vitamin A deficiency in Brazilian women of childbearing age. We conducted a systematic review with meta-analysis of studies that assessed vitamin A deficiency in women of childbearing age following the registered protocol (CRD42020171856). Independent peer researchers selected the studies retrieved from MEDLINE, Embase, Scopus and other sources. Data from the eligible studies were extracted in pairs and assessed for methodological quality. The prevalence of vitamin A deficiency (< 0·70 µmol/l or <0·20 µg/dl) and 95 % CI was combined by meta-analysis, and heterogeneity was estimated by I2. Out of 3610 screened records, thirty-two studies were included, which assessed 12 577 women from 1965 to 2017, mostly in maternity hospitals. Main limitations of the studies were in sample frame (30/32) and sampling method (29/32). Deficiency occurred in 13 % (95 % CI 9·4, 17·2 %; I² = 97 %) of all women and was higher in pregnant women (16·1 %; 95 % CI 5·6, 30·6 %; I² = 98 %) than non-pregnant women (12·3 %; 95 % CI 8·4, 16·8 %; I² = 96 %). The prevalence increased according to the decade, from 9·5 % (95 % CI 1·9­21·6 %; I² = 98 %) up to 1990, 10·8 % (95 % CI 7·9, 14·2 %; I² = 86 %) in the 2000s and 17·8 % (95 % CI 8·7, 29·0 %; I² = 98 %) in the 2010s. Over 10 % of Brazilian women in childbearing age were deficient in vitamin A. Higher prevalence was observed in pregnant women, and deficiency seemed to be increasing over the decades. Low representativeness of the studies, mainly based on convenience sampling that included pregnant, postpartum, lactating and non-pregnant women, as well as high heterogeneity, limits the findings.

Patients' perspectives on the relevance of biosimilars' outcomes in oncology: qualitative study with nominal group technique.

PURPOSE: We aimed to rate the importance of outcomes from a systematic review about biosimilars in oncology from patients' perspective. METHODS: This is a qualitative research with nominal group technique. Patients with cancer were selected by convenience sampling and invited for two mediated virtual meetings in 2022. Twelve outcomes from a systematic review on biosimilars for oncology developed following a protocol were explained in plain language to participants who classified them as critical, important, or not important according to the Grading of Recommendations Assessment, Development and Evaluation approach. We employed Iramuteq software for lexical categorization of the meeting transcripts, and content analysis for interpretation. RESULTS: Five women participated (three had metastatic cancer, one non-metastatic, one recurrent). Six outcomes were classified as critical: duration of response, progression-free survival, pathological complete response, overall survival, severe adverse events, and quality of life; three as important: mortality, event-free survival, and objective response; and three as non-important: neutralizing anti-drug antibody, any adverse event, and non-neutralizing anti-drug antibody. Duration of response, pathological complete response, severe adverse events, and quality of life were considered secondary in the review protocol, but critical by the patients. The main themes influencing the importance classification were related to the disease (progression and control) and treatment (recognition and healthcare setting). CONCLUSION: Patients rated most outcomes as critical or important, some of them previously regarded as secondary by the researchers, which reinforces the need to include stakeholders' perspectives in oncology research. Aspects of the disease progression and treatment effects influenced participants' judgment on outcomes' relevance.

Pharmaceutical policies: effects of policies regulating drug marketing.

BACKGROUND: The costs of developing new treatments and bringing them to the market are substantial. The pharmaceutical industry uses drug promotion to gain a competitive market share, and drive sale volumes and industry profitability. This involves disseminating information about new treatments to relevant targets. However, conflicts of interest can arise when profits are prioritised over patient care and its benefits. Drug promotion regulations are complex interventions that aim to prevent potential harm associated with these activities. OBJECTIVES: To assess the effects of policies that regulate drug promotion on drug utilisation, coverage or access, healthcare utilisation, patient outcomes, adverse events and costs. SEARCH METHODS: We searched Epistemonikos for related reviews and their included studies. To find primary studies we searched MEDLINE, CENTRAL, Embase, EconLit, Global Index Medicus, Virtual Health Library, INRUD Bibliography, two trial registries and two sources of grey literature. All databases and sources were searched in January 2023. SELECTION CRITERIA: We planned to include studies that assessed policies regulating drug promotion to consumers, healthcare professionals or regulators and third-party payers, or any combination of these groups.In this review we defined policies as laws, rules, guidelines, codes of practice, and financial or administrative orders made by governments, non-government organisations or private insurers. One of the following outcomes had to be reported: drug utilisation, coverage or access, healthcare utilisation, patient health outcomes, any adverse effects (unintended consequences), and costs. The study had to be a randomised or non-randomised trial, an interrupted time series analysis (ITS), a repeated measures (RM) study or a controlled before-after (CBA) study. DATA COLLECTION AND ANALYSIS: At least two review authors independently assessed eligibility for inclusion of studies. When consensus was not reached, any disagreements were discussed with a third review author.  We planned to use the criteria suggested by Cochrane Effective Practice and Organisation of Care (EPOC) to assess the risk of bias of included studies. For randomised trials, non-randomised trials, and CBA studies, we planned to estimate relative effects, with 95% confidence intervals (CI). For dichotomous outcomes, we planned to report the risk ratio (RR) when possible and adjusted for baseline differences in the outcome measures. For ITS and RM, we planned to compute changes along two dimensions: change in level and change in slope. We planned to undertake a structured synthesis following EPOC guidance.  MAIN RESULTS: The search yielded 4593 citations, and 13 studies were selected for full-text review. No study met the inclusion criteria. AUTHORS' CONCLUSIONS: We sought to assess the effects of policies that regulate drug promotion on drug use, coverage or access, use of health services, patient outcomes, adverse events, and costs, however we did not find studies that met the review's inclusion criteria. As pharmaceutical policies that regulate drug promotion have untested effects, their impact, as well as their positive and negative influences, is currently only a matter of opinion, debate, informal or descriptive reporting. There is an urgent need to assess the effects of pharmaceutical policies that regulate drug promotion using well-conducted studies with high methodological rigour.

Frequency of osteonecrosis in bisphosphonate users submitted to dental procedures: A systematic review.

OBJECTIVE: To determine the frequency of osteonecrosis of the jaw in bisphosphonate users submitted to dental procedures. METHODS: This systematic review searched the sources: MEDLINE, EMBASE, Web of Science, Scopus, and Virtual Health Library, with no restriction on language or publication date. Reviewers, in pairs and independently, selected the studies, extracted their data, and assessed the risk of bias. Meta-analyses were pooled using the DerSimonian and Laird random effects model. RESULTS: A total of 27 studies (5391 participants) were included. The most reported bisphosphonates were zoledronate (n = 17 studies) and alendronate (n = 19) for treating cancers (n = 11) and osteoporosis (n = 16), respectively. Twelve studies were of low methodological quality. The frequency of osteonecrosis was 2.7% (95% CI: 0.9-5.2%) and proved higher for intravenous [6.9% (0.7-17.3%)] than oral [0.2% (0.9-5.2%)] bisphosphonate use. No association between longer treatment duration and greater frequency of osteonecrosis was observed. CONCLUSIONS: Higher frequency of osteonecrosis was observed in intravenous bisphosphonate users submitted to dental extraction. Further studies collecting more detailed information on the bisphosphonates used and of greater methodological rigor are warranted to confirm these findings and better inform prescribers, dental surgeons, and other professionals on risks of bisphosphonate use in this patient group.

Data sources for drug utilization research in Latin American countries-A cross-national study: DASDUR-LATAM study.

PURPOSE: Drug utilization research (DUR) contributes to inform policymaking and to strengthen health systems. The availability of data sources is the first step for conducting DUR. However, documents that systematize these data sources in Latin American (LatAm) countries are not known. We compiled the potential data sources for DUR in the LatAm region. METHODS: A network of DUR experts from nine LatAm countries was assembled and experts conducted: (i) a website search of the government, academic, and private health institutions; (ii) screening of eligible data sources, and (iii) liaising with national experts in pharmacoepidemiology (via an online survey). The data sources were characterized by accessibility, geographic granularity, setting, sector of the data, sources and type of the data. Descriptive analyses were performed. RESULTS: We identified 125 data sources for DUR in nine LatAm countries. Thirty-eight (30%) of them were publicly and conveniently available; 89 (71%) were accessible with limitations, and 18 (14%) were not accessible or lacked clear rules for data access. From the 125 data sources, 76 (61%) were from the public sector only; 46 (37%) were from pharmacy records; 43 (34%) came from ambulatory settings and; 85 (68%) gave access to individual patient-level data. CONCLUSIONS: Although multiple sources for DUR are available in LatAm countries, the accessibility is a major challenge. The procedures for accessing DUR data should be transparent, feasible, affordable, and protocol-driven. This inventory could permit a comparison of drug utilization between countries identifying potential medication-related problems that need further exploration.

Perceived discrimination in health services and associated factors in Manaus Metropolitan Region, Brazil: a cross-sectional population-based study.

Objectives: Discrimination is the differentiated treatment of individuals due to prejudgments. Discriminatory practices in health care result in negative effects on patients' health. In Brazil, skin color represents the main form of racial discrimination, which may have an impact on the accessibility and quality of health care. The Brazilian Amazon lacks investigations on this topic at the population level. This study aims to estimate the prevalence of perceived discrimination in health services and associated factors in the Manaus Metropolitan Region, state of Amazonas, Brazil.Design: A population-based cross-sectional study was conducted with a probabilistic sample of adults interviewed in 2015. The associated factors were investigated by calculating the prevalence ratio (PR) using Poisson regression with robust variance.Results: A total of 4,001 participants were included. The overall prevalence of perceived discrimination was 12.9% (95% confidence interval [CI]: 11.8-13.9%). When compared to the reference categories, women (PR = 1.43; 95%CI: 1.20-1.70), individuals with brown skin color (Brazilian mixed race; PR = 1.33; 95%CI: 1.04-1.71), people who suffer from hypertension (PR = 1.27;95%CI: 1.03-1.57), and people who frequently used health services (p≤0.03) experienced more discrimination from health professionals.Conclusions: The prevalence of perceived discrimination in health services in Manaus Metropolitan Region is frequent and is associated with ethnic, social and health-related factors. Investments in inclusive public health policies and a better quality of health assistance are required to tackle this problem.

Seroprevalence of Epstein-Barr virus and cytomegalovirus infections in Presidente Figueiredo, Amazonas, Brazil.

Epstein-Barr virus (EBV) and cytomegalovirus (CMV) infections affect around 95% of the world's population. In Brazil, there are few epidemiological reports related to EBV and CMV infection, especially in the western Amazon region. This study aimed to estimate the seroprevalence of EBV and CMV infection in individuals residents in Presidente Figueiredo, Amazonas, Brazil. Blood samples of 443 individuals were tested for the presence of anti-EBV and anti-CMV IgG antibodies through an enzyme-linked immunosorbent assay. EBV (95.9%; 95% CI: 0.94;0.98), CMV (96.8%; 95% CI: 0.95;0.98) and CMV/EBV (93%;95% CI: 0.91-0.95) coinfection were highly prevalent in the study population. Children (1 to 5 years) not attending school were less susceptible to EBV (OR 0.15; 95% CI: 0.05-0.52; p = 0.017) and CMV infections (OR 0.05; 95% CI: 0.02 - 0.17; p < 0.0001). Teenagers at high school showed increased susceptibility to CMV infection (OR 4.65; 95%CI: 1.43-15.08; p = .013) and EBV/CMV co-infection (OR 3.04; 95%CI: 1.44-6.45; p = 0.005). The seroprevalence of CMV and EBV infections were preeminent and tend to increase with age in the study population. Either attendance to a daycare facility or primary school before the age of 5 years may increase the susceptibility to EBV or CMV infection.

Gender differences in the use of atypical antipsychotics in early-onset schizophrenia: a nationwide population-based study in Brazil.

BACKGROUND: The use of atypical antipsychotics for the treatment of schizophrenia and other mental disorders in populations under 18 years of age is increasing worldwide. Little is known about treatment patterns and the influence of gender differences, which may be a predictor of clinical outcomes. The aim of this study was to investigate gender differences in the use of atypical antipsychotics in patients with early-onset schizophrenia (EOS) assisted by the public health system in Brazil. METHODS: We conducted a cross-sectional study of outpatients with EOS aged 10 to 17 years who received at least one provision of atypical antipsychotics (clozapine, olanzapine, risperidone, quetiapine or ziprasidone) from a large Brazilian pharmaceutical assistance programme. Data were retrieved from a nationwide administrative database from 2008 to 2017. RESULTS: Of the 49,943 patients with EOS, 63.5% were males, and the mean age was 13.6 years old. The patients were using risperidone (62.5%), olanzapine (19.6%), quetiapine (12.4%), ziprasidone (3.3%) and clozapine (2.2%). We found gender differences, especially in the 13-17 year age group (65.1% for males vs. 34.9% for females, p < 0.001), in the use of risperidone (72.1% for males vs. 27.9% for females, p < 0.001) and olanzapine (66.5% for males vs. 33.5% for females, p < 0.001). Only in the 13 to 17 years age group were the prescribed doses of olanzapine (p = 0.012) and quetiapine (p = 0.041) slightly higher for males than for females. CONCLUSIONS: Our findings showed gender differences among patients diagnosed with EOS and who received atypical antipsychotics. More attention should be devoted to gender differences in research and clinical practice.

[Methicillin-resistant Staphylococcus aureus in the Americas: systematic review and metanalysis of prevalence in food-producing animalsStaphylococcus aureus resistente a la meticilina en la Región de las Américas: revisión sistemática y metanálisis de la prevalencia en la actividad agropecuaria]. / Staphylococcus aureus resistente à meticilina nas Américas: revisão sistemática e metanálise da prevalência na pecuária.

OBJECTIVE: To determine the prevalence of methicillin-resistant Staphylococcus aureus (MRSA) in animals used to produce foods in the Americas. METHOD: A systematic literature review was performed in the following databases: Scopus, Web of Science, MEDLINE, EMBASE, and Virtual Health Library. Articles published in the past 10 years, without language limits, were selected. The outcome of interest was the prevalence of MRSA in food-producing animals. Prevalence rates were meta-analyzed in grouped random effects models using the DerSimonian and Laird method. The geographic distribution of MRSA and the time trend of resistance were also analyzed. RESULTS: Of 19 studies included, 11 were performed in the United States and 11 analyzed pig samples. Five studies were performed in South America. The samples analyzed in the studies were collected in farming, processing, and retail sites. MRSA prevalence in the Americas was 7.6% (95%CI: 5.6-9.5%), and was higher in pigs [12.6% (95%CI: 7.0-18.2%)] followed by bovine cattle [2.4% (95%CI: 1.2-3.7%)] and poultry [1.8% (95CI%: 0.3-3.4%)]. MRSA prevalence was higher in pigs in North America and bovine cattle in Latin America. There was no significant variation in MRSH prevalence along the 10-year period analyzed. CONCLUSIONS: MRSA prevalence in food-producing animals in the Americas was higher in pigs, without significant changes across time.

OBJETIVO: Determinar la prevalencia de Staphylococcus aureus resistente a la meticilina (MRSA por su sigla en inglés) en animales destinados a la producción de alimentos en la Región de las Américas.

Las tasas de prevalencia se agruparon en metanálisis de efectos aleatorios por el método de DerSimonian y Laird. También se analizaron la distribución geográfica de los microorganismos resistentes y las tendencias de resistencia con el transcurso del tiempo. RESULTADOS: De los 19 estudios incluidos, 11 se realizaron en Estados Unidos y en 11 se analizaron muestras tomadas de cerdos. Se efectuaron cinco estudios en América del Sur. Las muestras analizadas se recogieron en lugares de cría, sacrificio y venta. La prevalencia de MRSA en la Región de las Américas fue de 7,6% (IC95%: 5,6-9,5%) con una tasa mayor en cerdos [12,6% (IC95%: 7,0-18,2%)], seguidos por bovinos [2,4% (IC95%: 1,2-3,7%)] y aves [1,8% (IC95%: 0,3-3,4%)]. Se observó una mayor prevalencia de MRSA en la población porcina de América del Norte y en la población bovina de América Latina. No hubo variación significativa de la prevalencia de resistencia en los diez años analizados. CONCLUSIONES: La prevalencia de MRSA en animales destinados a la producción de alimentos en la Región de las Américas fue mayor en cerdos, sin variación significativa de la prevalencia con el transcurso del tiempo.

Inequity in utilizing health services in the Brazilian Amazon: A population-based survey, 2015.

BACKGROUND: Although Brazil has a public and universal healthcare system, utilization of health services is marked by social and regional discrepancies. OBJECTIVE: To assess the prevalence and factors associated with underutilization of healthcare services in the Brazilian Amazon. METHOD: Cross-sectional, population-based study. Adults aged over 18 years old were selected through probabilistic sampling. Underutilization of healthcare services was defined as never seeing a physician or a dentist. Poisson regression with robust variance was performed to calculate prevalence ratios (PRs) and 95% confidence intervals (CIs). A complex sample design was considered. RESULTS: A total of 4001 individuals were included, of which 419 (10.4%; 95% CI, 9.5-11.4%) never visited a physician or a dentist. In the adjusted analysis, underutilization was higher among poorer people (PR = 3.32; 95% CI, 2.16-5.11), men (PR = 1.34; 95% CI, 1.10-1.65), people with brown skin color (Brazilian mixed race; PR = 1.34; 95% CI, 1.02-1.76), and people who are separated (PR = 1.40; 95% CI, 1.01-1.94) and widowed (PR = 1.55; 95% CI, 1.02-2.37), when compared with the reference categories. Individuals with informal jobs, those who are retired, students/housewives, and unemployed people were more vulnerable to underutilization than formal workers (P < .04). CONCLUSION: Underutilization of healthcare services occurs in one-tenth of adults in Manaus Metropolitan Region and is associated with social and economic inequities.

Rapid response in health technology assessment: a Delphi study for a Brazilian guideline.

BACKGROUND: Rapid response in health technology assessment is a synthesis of the best available evidence prepared in a timely manner to meet specific demands. We build a consensus among Brazilian specialists in health technology assessment to propose guidelines for the development of rapid response. METHODS: Based on a systematic review that proposed eight methodological steps to conduct rapid response, we applied a modified Delphi technique (without open questions in the first round) to reach consensus among Brazilian experts in health technology assessment. Twenty participants were invited to judge the feasibility of each methodological step in a five-point Likert scale. Consensus was reached if the step had 70% positive approval or interquartile range ≤ 1. RESULTS: The achievement of consensus was reached in the second round. Between the first and the second round, we scrutinized all points reported by the experts. The Delphi panel reached consensus of eight steps: definition of the structured question of rapid response (with a restricted scope); definition of the eligibility criteria for study types (preferably systematic reviews); search strategy (language and data limits) and sources of information (minimum two); selection of studies (independently by two responders); critical appraisal of the included studies and the risk of bias for the outcomes of interest; data extraction from the included articles; summary of evidence; and preparation of the report. CONCLUSIONS: The guidelines for rapid response in health technology assessment may help governments to make better decisions in a short period of time (35 days). The adoption of methodological processes should improve both the quality and consistency of health technology assessments of rapid decisions in the Brazilian setting.

Prevalence of Self-Reported Chronic Diseases and Health Services Utilization by Ethnic Minorities in Manaus Metropolitan Region.

Objectives: To assess the prevalence of, and associated factors to, self-reported chronic diseases and health care utilization by ethnicity in the Manaus Metropolitan Region. Methods: We conducted a cross-sectional, population-based survey from May through August 2015. Using probabilistic sampling in three stages, we recruited adults aged ≥18 years. Ethnicity was self-identified as White, Black, Yellow, Brown (Brazilian mixed-race), and Indigenous. We calculated adjusted prevalence ratios (PR) and 95% CI of chronic diseases and health service utilization for each ethnic minority and compared the data using Poisson regression with data from White respondents. Results: In this study, we interviewed 4,001 people. Of these, 15.9% were White, 7.5% Black, 3.4% Yellow, 72.1% Brown, and 1.0% Indigenous. Indigenous respondents had the highest prevalence of self-reported hypertension (29.4%), diabetes (12.3%) and hypercholesterolemia (17.0%) among the ethnic respondent groups. Compared with the White population, Browns had less health insurance coverage (PR=.76; 95% CI: .62-.93) and reported hypertension (PR=.84; 95% CI: .72-0.98) and diabetes (PR=.69; 95% CI: .51-.94) less frequently. Yellows visited the doctor more frequently than Whites (PR=1.13; 95% CI: 1.04-1.22), with no significant difference in prevalence of diseases. Conclusions: Indigenous respondents had higher prevalence rates of the investigated diseases. Compared with Whites, Brown respondents had lower rates of self-reported arterial hypertension and diabetes, as well as lower rates of private health insurance coverage.

Healthcare Professional's Perception of Patient Safety Measured by the Hospital Survey on Patient Safety Culture: A Systematic Review and Meta-Analysis.

OBJECTIVE: To assess the culture of patient safety in studies that employed the hospital survey on patient safety culture (HSOPS) in hospitals around the world. METHOD: We searched MEDLINE, EMBASE, SCOPUS, CINAHL, and SciELO. Two researchers selected studies and extracted the following data: year of publication, country, percentage of physicians and nurses, sample size, and results for the 12 HSOPS dimensions. For each dimension, a random effects meta-analysis with double-arcsine transformation was performed, as well as meta-regressions to investigate heterogeneity, and tests for publication bias. RESULTS: 59 studies with 755,415 practitioners surveyed were included in the review. 29 studies were conducted in the Asian continent and 11 in the United States. On average studies scored 9 out of 10 methodological quality score. Of the 12 HSOPS dimensions, six scored under 50% of positivity, with "nonpunitive response to errors" the lowest one. In the meta-regression, three dimensions were shown to be influenced by the proportion of physicians and five by the continent where survey was held. CONCLUSIONS: The HSOPS is widely used in several countries to assess the culture of patient safety in hospital settings. The culture of culpability is the main weakness across studies. Encouraging event reporting and learning from errors should be priorities in hospitals worldwide.

Health-related quality of life in the Brazilian Amazon: a population-based cross-sectional study.

BACKGROUND: To analyze perceptions of health-related quality of life and associated factors in populations from the Manaus Metropolitan Region. METHODS: We conducted a population-based cross-sectional study from May to August 2015. Adults aged 18 years and older were selected using probabilistic three-phase cluster sampling and stratified by sex and age, based on official estimates. Quality of life data were collected using the European Quality of Life 5-Dimensions 3-Levels (EQ-5D-3L) along with socioeconomic, demographic, and health perception data. Utility scores were calculated using the Brazilian version of the EQ-5D-3L. Descriptive statistics were derived, and a multivariate Tobit regression model with correction for complex sampling was performed to identify the variables that influence utility levels. RESULTS: A total of 4001 participants were included. The average utility score was 0.886 (95% confidence interval [CI]: 0.881-0.890) with significant differences according to living area (the capital (0.882 ± 0.144) or inner cities (0.908 ± 0.122; p < 0.001)). The dimension for which the highest proportion of people reported moderate to severe problems was pain/discomfort (39%), followed by anxiety/depression (18%). Men had a higher quality of life than women (ß = 0.041, p < 0.001). Not working was a factor that increased quality of life compared with being formally employed (ß = 0.031, p = 0.037). The poorest people had a lower quality of life than the richest people (ß = -0.118, p < 0.001). Better health perceptions increased utility scores (p < 0.001), while being separated decreased the scores (ß = -0.052, p = 0.001). CONCLUSION: Health-related quality of life in the Manaus Metropolitan Region was high, as expected for the general population, and was higher among individuals who lived in the inner cities, men and those in higher social classes. Gender discrepancies and differences in quality of life between the capital and inner cities should be further investigated.

Oral herbal medicines marketed in Brazil for the treatment of osteoarthritis: A systematic review and meta-analysis.

Herbal medications are commonly used to manage symptoms associated with osteoarthritis (OA). This systematic review evaluated the effectiveness and safety of oral medications used in Brazil for the treatment of OA. Randomized clinical trials involving adults with OA treated by a herbal medicine or a control group were eligible. The primary outcomes measured were pain, physical function, swelling, stiffness and quality of life; and the secondary outcomes were adverse events, activity limitations and treatment satisfaction. Sixteen studies were included (n = 1,741 patients) in the systematic review and nine studies in the meta-analysis, representing 6 of the 13 herbal medicines studied: Boswellia serrata (n = 2), Curcuma longa (n = 3), Harpagophytum procumbens (n = 1), Salix daphnoides (n = 3), Uncaria guianensis (n = 2) and Zingiber officinale (n = 5). B. serrata was more effective than both placebo and valdecoxib for improvement of pain and physical function. No difference was observed for H. procumbens, C. longa and U. guianensis compared with control. Z. officinale showed improvement of pain over placebo. The evidence was insufficient to support the effective and safe use of these herbal medicines, because the quality of evidence of studies was low. This study guides managers of the Brazilian public health system and prescribers in decision-making regarding the use of these herbal medicines for OA. Copyright © 2017 John Wiley & Sons, Ltd.

[Economic evaluation of health technologies: checklist for critical analysis of published articles]. / Estudos de avaliação econômica de tecnologias em saúde: roteiro para análise crítica.

OBJECTIVE: To propose a tool for critical analysis of economic evaluation studies based on a synthesis of checklists and guidelines available in the literature. METHODS: The following databases were searched: MEDLINE, Embase, Centre for Reviews and Dissemination, and International Society for Pharmacoeconomics and Outcomes Research. Two investigators independently selected the studies and extracted the data of interest. The number of questions that the checklists contained were counted on the following domains: study design, measurement of costs and health outcomes, analysis and interpretation of results, and general information. A matrix containing the items in each domain was constructed, and a tool for critical analysis was built based on that matrix. RESULTS: The literature search retrieved 406 non-duplicated articles, 19 of which were included in the study. Five hundred sixty-six questions were identified in the checklists employed in these studies: 109 (19%) dealt with health outcomes, 93 (16%) with quantification of costs, 73 (13%) with modeling, 54 (10%) with generalization of findings, and 52 (9%) with uncertainty. The resulting critical analysis checklist contains 32 questions organized into four domains: study design, measurement of costs and health outcomes, analysis and interpretation of results, and general information. CONCLUSIONS: The proposed critical analysis checklist is useful to standardize the assessment of the quality of evidence in all types of economic evaluations.

Tuberculosis incidence in Brazil: time series analysis between 2001 and 2021 and projection until 2030.

OBJECTIVE: To assess the incidence of tuberculosis in Brazil between 2001 and 2022 and estimate the monthly incidence forecast until 2030. METHODS: This is a time-series study based on monthly tuberculosis records from the Notifiable Diseases Information System and official projections of the Brazilian population. The monthly incidence of tuberculosis from 2001 to 2022 was evaluated using segmented linear regression to identify trend breaks. Seasonal autoregressive integrated moving average (Sarima) was used to predict the monthly incidence from 2023 to 2030, deadline for achieving the sustainable development goals (SDGs). RESULTS: There was a decrease in incidence between January/2001 and December/2014 (4.60 to 3.19 cases-month/100,000 inhabitants; ß=-0.005; p<0.001), followed by an increase between January/2015 and March /2020 (ß=0.013; p<0.001). There was a sharp drop in cases in April/2020, with the onset of the pandemic, and acceleration of the increase in cases since then (ß=0.025; p<0.001). A projection of 124,245 cases in 2030 was made, with an estimated incidence of 4.64 cases-month/100,000 inhabitants, levels similar to those in the 2000s. The Sarima model proved to be robust, with error of 4.1% when removing the pandemic period. CONCLUSION: The decreasing trend in tuberculosis cases was reversed from 2015 onwards, a period of economic crisis, and was also impacted by the pandemic when there was a reduction in records. The Sarima model can be a useful forecasting tool for epidemiological surveillance. Greater investments in prevention and control need to be made to reduce the occurrence of tuberculosis, in line with the SDGs.

Self-rated health according to sex and associated factors in Manaus, Brazil, 2019: a population-based cross-sectional study.

OBJECTIVE: To assess the prevalence and factors associated with poor self-rated health according to respondents' sex in Manaus, Brazil. METHODS: This was a cross-sectional population-based study with adults in Manaus in 2019. Adjusted prevalence ratios and 95% confidence intervals (95%CI) were calculated using Poisson regression following a hierarchical model. RESULTS: Poor self-rated health occurred in 35.2% (95%CI 33.3;37.2) of the 2,321 participants and was higher in females (PR = 1.27; 95%CI 1.13;1.43). In the general population, among both sexes, poor self-rated health was higher among the oldest, those with moderate and severe food insecurity and with chronic diseases (p-value < 0.05). Among females, poor health was also higher among the evangelical and those with mild food insecurity. Among males, self-rated health was also poorer among the retired and those with education below elementary level (p-value < 0.001). CONCLUSION: The female sex had the poorest health rating, influenced by morbidity and access to food.

Zinc supplementation for treating diarrhea in children: a systematic review and meta-analysis.

OBJECTIVE: To update the available evidence about zinc use for treating diarrhea in children and to assess its effect on the malnourished population, a subgroup that has not been fully explored in previous analyses. METHODS: A systematic review was performed of randomized clinical trials that assessed children up to 5 years old with acute diarrhea who received zinc supplementation. Controls received a placebo or oral rehydration therapy. After searching the main databases, without language restrictions, two independent reviewers selected eligible studies, extracted the data, and assessed the risk of bias of included studies. Meta-analyses were calculated using Mantel-Haenszel or inverse variance random effects. RESULTS: Eighteen of 1 041 studies retrieved were included in the review (n = 7 314 children). Zinc was beneficial for reducing the duration of diarrhea in hours (mean difference [MD] = -20.12, 95% confidence interval [CI] = -29.15 to -11.09, I² = 91%). The effect was greater in malnourished children (MD = -33.17, 95% CI = -33.55 to -27.79, I² = 0%). Diarrhea prevalence on days 3, 5, and 7 was lower in the zinc group. The incidence of vomiting was significantly greater in the group that received zinc than in the control group. Included randomized controlled trials were of low risk of bias in most domains assessed. CONCLUSIONS: Oral zinc supplementation significantly decreases diarrhea duration and has a greater effect on malnourished children. Zinc supplementation seems to be an appropriate public health strategy, mainly in areas of endemic deficiencies.

Use of atypical antipsychotics in the treatment of schizophrenia in the Brazilian National Health System: a cohort study, 2008-2017.

OBJECTIVE: to investigate sociodemographic and clinical characteristics of users of atypical antipsychotics receiving care via the Specialized Component of Pharmaceutical Assistance (Componente Especializado da Assistência Farmacêutica - CEAF), for the treatment of schizophrenia in Brazil, between 2008 and 2017. METHODS: this was a retrospective cohort study using records of the authorizations for high complexity procedures retrieved from the Outpatient Information System of the Brazilian National Health System, from all Brazilian states. RESULTS: of the 759,654 users, 50.5% were female, from the Southeast region (60.2%), diagnosed with paranoid schizophrenia (77.6%); it could be seen a higher prevalence of the use of risperidone (63.3%) among children/adolescents; olanzapine (34.0%) in adults; and quetiapine (47.4%) in older adults; about 40% of children/adolescents were in off-label use of antipsychotics according to age; adherence to CEAF was high (82%), and abandonment within six months was 24%. CONCLUSION: the findings expand knowledge about the sociodemographic and clinical profile of users and highlight the practice of off-label use.
