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.

Prevalence of antidepressant use in Brazil: a systematic review with meta-analysis

Objectives: To estimate the prevalence of antidepressant use in Brazil. Methods: We conducted a systematic review with searches in MEDLINE, Embase, Scopus, LILACS, and SciELO up to May 2023. Two researchers independently selected studies, extracted data, and assessed the methodological quality. We pooled the prevalence of antidepressant use using meta-analyses of proportions (Freeman-Tukey transformation) and estimated heterogeneity by the I2 statistic. OR meta-analyses of antidepressant use by sex were calculated (men as reference) and between-study variation was explored by meta-regressions. Results: Out of 3,299 records retrieved, 23 studies published in 28 reports were included, with a total of 75,061 participants. The overall prevalence of antidepressant use was 4.0% (95%CI 2.7-5.6%; I2 = 98.5%). Use of antidepressants in the previous 3 days was higher in women (12.0%; 95%CI 9.5-15.1%; I2 = 0%) than men (4.6%; 95%CI 3.1-6.8%; I2 = 0%) (p < 0.001; OR = 2.82; 95%CI 1.72-4.62). Gender differences were particularly higher for antidepressant use in the previous year (women: 2.3%; 95%CI 1.6-3.1; I2 = 37.6% vs. men: 0.5%; 95%CI 0.2-1.0%; I2 = 0%, p < 0.001; OR = 4.18; 95%CI 2.10-8.30). Between-study variation in the overall prevalence of antidepressant use significantly increased with mean participant age (p = 0.035; residual I2 = 0%; regression coefficient = 0.003). Conclusion: Four out of every 100 Brazilians used antidepressants in this 3-decade assessment. Use increased with age and was more prevalent in women compared to men. Registration number: PROSPERO CRD42022345332.

RESUMO Objetivo: Avaliar a incidência de tuberculose no Brasil entre 2001 e 2022 e estimar a previsão de incidência mensal até 2030. Métodos: Trata-se de estudo de série temporal que partiu de registros mensais de tuberculose do Sistema de Informação de Agravos de Notificação e projeções oficiais da população brasileira. Avaliou-se a incidência mensal de tuberculose entre 2001 e 2022 por meio de regressão linear segmentada para identificar quebras de tendências. Utilizou-se o modelo autorregressivo integrado de médias móveis sazonais (Sarima) para prever a incidência mensal de 2023 a 2030, prazo para alcançar os objetivos de desenvolvimento sustentável (ODS). Resultados: Observou-se diminuição da incidência entre janeiro/2001 e dezembro/2014 (de 4,60 para 3,19 casos-mês/100 mil habitantes; β=-0,005; p<0,001), seguida de aumento entre janeiro/2015 e março/2020 (β=0,013; p<0,001). Houve queda abrupta de casos em abril/2020, com início da pandemia e aceleração do aumento de casos desde então (β=0,025; p<0,001). Projetaram-se 124.245 casos de tuberculose em 2030, com incidência estimada em 4,64 casos-mês/100 mil habitantes, patamares da década de 2000. O modelo Sarima mostrou-se robusto, com erro de 4,1% ao remover o período pandêmico. Conclusão: A tendência decrescente nos casos de tuberculose foi revertida a partir de 2015, período de crises econômicas, e foi também impactada pela pandemia quando houve redução nos registros. O modelo Sarima pode ser uma ferramenta de previsão útil para a vigilância epidemiológica. Maiores investimentos na prevenção e controle precisam ser aportados para reduzir a ocorrência de tuberculose, em linha com os ODS.

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.

Two researchers independently selected studies, extracted data and assessed the methodological quality. We combined the prevalence of antidepressant use using meta-analyses of proportions by Freeman-Tukey and estimated heterogeneity by I². Odds ratio (OR) meta-analyses of antidepressant use by sex were calculated (men as reference) and between-study variation was explored by meta-regressions. RESULTS: Out of 3,299 records, 23 studies published in 28 reports were included. The overall prevalence of antidepressant use was 4.0% (95%CI 2.7-5.6%; I2=98.5%). Use of antidepressants in the previous 3 days was higher in women (12.0%; 95%CI 9.5-15.1%; I2=0.0%) than men (4.6%; 95%CI 3.1-6.8%; I2=0.0%), p<0.001; OR=2.82; 95%CI 1.72-4.62. Gender differences were particularly higher for antidepressant use in the previous year (women: 2.3%; 95%CI 1.6-3.1; I2=37.6% versus men: 0.5%; 95%CI 0.2-1.0%; I2=0.0%, p<0.001; OR=4.18; 95%CI 2.10-8.30). Between-study variation in the overall prevalence of antidepressant use significantly increased with participants' mean age (p=0.035; residual I²=0.0%; regression coefficient=0.003). CONCLUSIONS: Four in every 100 Brazilians use antidepressants; use increased with age and was higher in women compared to men.

Prevalence of psychotropic and antidepressant use in a Brazilian Amazon city: analysis of two cross-sectional studies.

This article aims to assess the prevalence of psychotropic and antidepressant use and associated factors in a Brazilian Amazon city. Two cross-sectional studies conducted in Manaus in 2015 and 2019 with adults selected by probabilistic sampling. Prevalence ratios (PR) and 95% confidence intervals (95%CI) were calculated by Poisson regression with robust variance. 3,479 participants were included in 2015 and 2,321 in 2019; 2.0% used psychotropics in 2015 and 2.7% in 2019. Antidepressants were used by 0.4% (2015) and 1.4% (2019). Psychotropic use was lower in younger (PR = 0.41; 95%CI: 0.19-0.90), partnerless (PR = 0.64; 95%CI: 0.44-0.93), and informal workers (PR=0.47; 95%CI: 0.25-0.86), but higher in people with poor health (PR=2.86; 95%CI: 1.71-4.80), multimorbidity (PR = 3.24; 95%CI: 1.87-5.60), and who visited doctors (PR = 3.04; 95%CI: 1.45-6.38) or dentists (PR = 1.50; 95%CI: 1.08-2.10). Antidepressant use was higher in 2019 (PR = 2.90; 95%CI: 1.52-5.54), people with poor health (PR = 2.77; 95%CI: 1.16-6.62), and multimorbidity (PR = 8.72; 95%CI: 2.71-28.00), while lower in informal workers (PR = 0.33; 95%CI: 0.12-0.87) and unemployed (PR = 0.26; 95%CI: 0.08-0.81). Use of psychotropics remained stable in Manaus from 2015 to 2019, while antidepressant use more than tripled, which was marked by social inequalities.

Prevalence of psychotropic and antidepressant use in a Brazilian Amazon city: analysis of two cross-sectional studies / Prevalência de uso de psicotrópicos e antidepressivos em uma cidade da Amazônia brasileira: análise de dois estudos transversais

O uso de psicotrópicos permaneceu estável em Manaus de 2015 a 2019, enquanto o de antidepressivos triplicou, sendo marcados por desigualdades sociais.

Prevalence of Physical Violence Against Brazilian Women: Systematic Review and Meta-Analysis.

Violence against women is a major problem in Brazil, but data on its prevalence are scarce. We aimed to estimate the prevalence of physical violence against women in Brazil. We conducted a systematic review and meta-analysis of the prevalence of physical violence against women. Population-based researches that assessed physical violence in Brazilian women were searched on MEDLINE, Embase, Scopus, and VHL/BIREME. The last search update was carried out in March 2020. Two researchers selected the studies, extracted the data, and assessed the quality of the eligible studies. Summary of prevalence and 95% confidence interval (CI) was calculated using Freeman-Tukey double arccosine transformation, weighted by the official local population size. Heterogeneity was estimated by I 2 and investigated by meta-regression analyses. Of 3,408 reports, 13 studies carried out from 1999 to 2016 (n = 25,781 women) were included. Most studies had limitations on sample size (5/13) and response rate (7/13). The prevalence of physical violence was 22.4% in lifetime (95% CI [21.6, 23.2%]; I 2 = 99.0%), and 11.5% in previous year (95% CI [11.1, 11.9%]; I 2 = 99.5%). Assuring privacy during interview significantly increased the prevalence (p = .028; residual I 2 = 80.0%). Higher prevalence was also observed in studies with adequate sample source, validated questionnaire, and privacy (in both recall periods), potentially due to lower risk of nonresponse bias. Over two in 10 Brazilian women suffered physical violence during their lives, and over one tenth, in the previous year. Measurement of outcome affected the prevalence; privacy should be assured for the interviewee for future reliable estimates in the country.

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.

Trends in sales of antidepressants in Brazil from 2014 to 2020: A time trend analysis with joinpoint regression.

BACKGROUND: This study aimed to investigate the trends in antidepressants sales in Brazil. METHODS: We performed a joinpoint analysis of antidepressants sales in Brazil from 2014 to 2020, recorded in the Brazilian National Controlled Products Management System. The primary outcomes were the defined daily dose per 1000 inhabitants per day (DID) and the market shares for each antidepressant per year. We used joinpoint regression to assess the changes in antidepressant consumption in DID to obtain the average annual percent change (AAPC) and 95 % confidence intervals (95 % CI). Changes in market shares were tested by chi-square trend test (p < 0.05 as significant). RESULTS: From 2014 to 2020, 42,252,989 antidepressant sales were recorded in the system. Antidepressant sales increased from 13.7 to 33.6 DID in the period (AAPC: 15.7; 95 % CI: 13.0-18.4; p < 0.001); the largest increases were observed for serotonin reuptake inhibitors and 'other' antidepressants (including serotonin-norepinephrine reuptake inhibitors), whereas tricyclics remained steady. Escitalopram and sertraline were the most sold drugs. Market share of serotonin reuptake inhibitors decreased, particularly for paroxetine (13.1 % to 6.5 %; p = 0.016), while 'other' antidepressants' market share expanded from 21.9 % to 33.3 % (p = 0.027), especially for desvenlafaxine (2.9 % to 14.3 %; p < 0.001). LIMITATIONS: The dataset does not include antidepressants dispensed in hospitals, public services, and compounding pharmacies, neither their therapeutic indications. CONCLUSION: Sales of antidepressants significantly increased in Brazil from 2014 to 2020, which were mainly driven by higher prescriptions of serotonin reuptake inhibitors and 'other' antidepressants classes. Market share changes seem to be driven by novelty of products.

Potential Drug Interactions in Adults Living in Manaus: A Real-World Comparison of Two Databases, 2019.

Objectives: Drug information systems are commonly used by professionals to assist in the identification of drug interactions and to ensure the safe use of medications. Real-world evidence about the comparison of different drug interaction sources is scarce. We aimed to compare two drug interaction databases to identify interactions in a population-based survey. Materials and Methods: This is a cross-sectional study based on a previous survey performed in the city of Manaus, Brazil, in 2019. We included adults aged 18 years and over, who used two or more medicines 15 days before the interview. To assess potential drug interactions, we searched Micromedex and UpToDate databases. The primary outcome was the prevalence of potential drug interactions in each database. Weighted Kappa statistics were calculated to assess agreement on the presence of drug interaction, documentation and severity. Results: A total of 752 participants were included in the study. The prevalence of drug interactions was 43.8% [95% confidence interval (CI): 40.2, 47.3%] in UpToDate and 30.2% (95% CI: 26.9, 33.5%), in Micromedex. The agreement related to drug interactions between the two databases was fair (Kappa: 0.631). For severity (Kappa: 0.398) and documentation (Kappa: 0.311), the agreement was poor. Conclusion: Agreement among compared databases was sub-optimal. Better quality and transparency of evidence available in drug interaction sources are needed to support informed healthcare professionals' decision.

Trends in Brazilian market of antidepressants: A five-year dataset analysis.

Introduction: Depression is an emotional disorder associated with morbidities and disabilities worldwide. The growing use of antidepressants is a concern for health managers because there are still unanswered questions on the effectiveness and safety of these medicines. Drug sales have increased in Brazil in recent years, but investigations on antidepressants sales are not available. We aimed to describe the trends in the antidepressant commerce in Brazil in a five-year period. Materials and Methods: We performed an ecological study on antidepressant sales in Brazil, from November 2014 to October 2019, using data from IQVIA™, a data provider of pharmaceutical sales. Antidepressants were coded by the Anatomical Therapeutic Chemical classification system, and sales were presented in defined daily doses (DDDs) and DDDs per 1,000 inhabitants per day (DIDs). The results were expressed in absolute quantities and growth rates. Results: The analyzed dataset contained 23 active substances in 780 products. The total sales of antidepressants increased from 23.3 DIDs in November 2014 to 38.3 DIDs in October 2019 (p = 0.002). Selective serotonin reuptake inhibitors were the most sold category of drugs (+5.7 million DDDs) in the period. 'Other' antidepressants presented the largest growth rate (104.7%). Individually, the most sold active substance was escitalopram (+1.8 million DDDs), and vortioxetine had the largest growth rate (336.2%). Tricyclic sales remained unchanged, and monoamine oxidase inhibitors had low and even decreasing sales (-9.5%). Discussion: The total sales of antidepressants increased in Brazil from November 2014 to October 2019. The higher sale volumes of selective serotonin reuptake inhibitors and higher growth rate of 'other' antidepressants, with low sale volume of tricyclics and a decrease of monoamine oxidase inhibitors, suggest the replacement of older drugs by newer ones following a global trend. Therapeutic advances and commercial promotion efforts on new products might explain these findings.

Prevalence and factors associated with polypharmacy and potential drug interactions in adults in Manaus, Amazonas state, Brazil: a cross-sectional population-based study, 2019. / Prevalência e fatores associados à polifarmácia e potenciais interações medicamentosas em adultos na cidade de Manaus: estudo transversal de base populacional, 2019.

OBJECTIVE: To assess the prevalence and factors associated with polypharmacy and the presence of potential drug interactions in Manaus, Amazonas state, Brazil, in 2019. METHODS: This was a population-based cross-sectional study conducted with adults aged ≥ 18 years. The presence of drug interactions among people on a polypharmacy regimen (≥ 5 drugs) was investigated on the Micromedex database. Prevalence ratios (PR) with 95% confidence intervals (95%CI) were calculated using Poisson regression model with robust variance, following hierarchical analysis and considering the complex sample design. RESULTS: Of the 2,321 participants, 2.8% (95%CI 2.1;3.6) were on polypharmacy regimen, of whom, 74.0% presented drug interactions, usually with four or more drug interactions per person (40.4%) and high severity (59.5%). Polypharmacy was higher among older adults (PR = 3.24; 95%CI 1.25;8.42), people with poor health (PR = 2.54; 95%CI 1.14;5.67), previous hospitalization (PR = 1.90; 95%CI 1.09;3.32) and multimorbidity (PR = 3.20; 95%CI 1.53;6.67). CONCLUSION: Polypharmacy was more frequent among older adults and people with medical problems, who presented more drug interactions.

Relationship between depressive symptoms, burnout, job satisfaction and patient safety culture among workers at a university hospital in the Brazilian Amazon region: cross-sectional study with structural equation modeling

ABSTRACT BACKGROUND: Workplaces can be sources of mental distress. In healthcare services, this can also affect patients. OBJECTIVE: To assess the prevalence of and factors associated with depressive symptoms, burnout, job satisfaction and patient safety culture and the relationships between these constructs, among healthcare workers. DESIGN AND SETTING: Cross-sectional study in a university hospital in Manaus, Brazil. METHODS: Randomly selected workers were interviewed based on Brazilian-validated tools. We calculated the prevalence ratio (PR) and 95% confidence interval (CI) of depressive symptoms and burnout using Poisson regression with robust variance; and the β-coefficient of safety culture and job satisfaction using linear regression. Outcome relationships were assessed using partial least-squares structural equation modeling. RESULTS: 300 professionals were included; 67.3% were women. The prevalence of depressive symptom was 19.0% (95% CI: 14.5; 23.5%) and burnout, 8.7% (95% CI: 5.2; 12.3%). Lack of work stability increased depression (PR = 1.88; 95% CI: 1.17; 3.01) and burnout (PR = 2.17; 95% CI: 1.03; 4.57); and reduced job satisfaction (β = -11.93; 95% CI: -18.79; -5.07). Depressive symptoms and burnout were positively correlated, as also were job satisfaction and safety culture (P < 0.001); job satisfaction was negatively correlated with burnout (P < 0.001) and depression (P = 0.035). CONCLUSION: Impermanent employment contracts increased depression and burnout and reduced job satisfaction. Job satisfaction reduced poor mental health outcomes and increased safety culture. Job satisfaction and safety culture were directly proportional (one construct increased the other and vice versa), as also were depression and burnout. Better working conditions can provide a virtuous cycle of patient safety and occupational health.
