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.

Assessment of the implementation of pharmacist prescribing: Challenges and pathways for ambulatory practice.

BACKGROUND: Prescribing by pharmacists is an increasingly common practice worldwide. In Brazil regulation of this practice began in 2013, and the practice remains unexplored as a research topic. OBJECTIVE: We aimed to explore and gain insights into pharmacist prescribing practices in Brazil and assessing pharmacist's perceptions of their training and preparedness to prescribe medications. METHODS: A cross-sectional survey was conducted between October 2022 and March 2023 via convenience sampling. Data were collected using an online questionnaire covering sociodemographic issues, academic training, prescribing practices, and perceptions regarding the provision of pharmacist prescribing in ambulatory care. Exploratory descriptive analysis and Poisson regression were performed to estimate the associations between pharmacist characteristics and their practices in prescribing medicines. RESULTS: Among the 305 valid responses, 58.7% of the outpatient pharmacists stated that they had not prescribed any medication in the previous three years. Over-the-counter medication prescriptions were most common (42.0%). Only 4.6% of respondents had prescribed prescription-only medicines provided through collaborative agreement, with 2.6% reporting that they had adjusted doses, and 2.3% played a role in prescription renewal. Pharmacists living in Northeast regions tended to be more active prescribers (PR = 1.42; 95%CI 1.03-2.18), whereas those in primary healthcare (PR = 0.61; 95%CI 0.39-0.96) and self-declared Black pharmacists (PR = 0.30; 95%CI 0.10-0.97) prescribed less. Respondents strongly believed in the pharmacist's role as a prescriber, although they remained ambivalent regarding their responsibility for patient outcomes. Progress barriers include infrastructure gaps and strained relationships with physicians. CONCLUSIONS: This study suggests that pharmacists in Brazil predominantly prescribe over-the-counter medications, and variations in setting, region, and race can influence prescribing by pharmacist in ambulatory care.

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.

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.

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

OBJECTIVE: 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 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.

Influence of the ethical climate on workers' health among healthcare professionals: a systematic review.

OBJECTIVE: To evaluate the influence of the ethical climate on workers' health among healthcare professionals. METHOD: Systematic review and meta-analysis conducted in MEDLINE/PubMed, EMBASE, SciVerse Scopus (Elsevier), Cumulative Index to Nursing and Allied Health Literature and Web of Science. Trained reviewers performed the selection, data extraction, and assessment of methodological quality. Meta-analysis was applied for data synthesis. RESULTS: Among the 2644 studies, 20 were included for analysis, in which three (15.0%) articles were classified as high quality (score ≥ 80%), while 17 (85.0%) were classified as regular (score 50-79%). There was a moderate negative correlation between the ethical climate and overall moral distress (r=-0.43; 95%CI -0.50; -0.36) and the frequency of moral distress (r=-0.36; 95%CI -0.45; -0.25), as well as the positive and strong correlation between ethical climate and job satisfaction (r=0.71; 95%CI 0.39-0.88). CONCLUSION: The negative and positive perception of the ethical climate among healthcare professionals, respectively, influenced the increase in moral distress and job satisfaction.

Health services utilization in the Brazilian Amazon: panel of two cross-sectional studies.

OBJECTIVE: To investigate the use of health services among adults living in Manaus, Amazonas. METHODS: This was a panel of two cross-sectional studies conducted in Manaus in 2015 and 2019. Individuals aged ≥ 18 years were selected by probabilistic sampling and interviewed at home. The study outcomes were doctor visits and hospitalizations in the previous 12 months, and unmet surgical needs. Variations between 2015 and 2019 were tested using chi-squared goodness-of-fit test. Poisson regression with robust variance was employed to calculate the prevalence ratios (PR) of the outcomes with 95% confidence intervals (95%CI). RESULTS: The surveys included 5,800 participants in total. Visits to the doctor decreased from 2015 (78.7%) to 2019 (76.3%; p < 0.001), hospital admissions increased from 2015 (7.9%) to 2019 (11.5%; p < 0.001), and unmet surgical needs decreased in the period (15.9% to 12.1%; p < 0.001). These variations were particularly observed in vulnerable individuals - sicker; poorer; non-whites; and those belonging to lower social classes, with less access to education, formal jobs, and health insurance (p < 0.05). Doctor visits were higher in people with fair health status (PR = 1.09; 95%CI 1.06-1.12), health insurance (PR = 1.13; 95%CI 1.09-1.17), and chronic diseases (p < 0.001) but lower in men (PR = 0.87; 95%CI 0.84-0.90) and informal workers (PR = 0.89; 95%CI 0.84-0.94). Hospitalizations were higher in people with worse health statuses (p < 0.001), without partners (PR = 1.27; 95%CI 1.05-1.53), and with multimorbidity (PR = 1.68; 95%CI 1.33-2.12) but lower in men (PR = 0.55; 95%CI 0.44-0.68), older adults (p < 0.001), informal workers (PR = 0.67; 95%CI 0.51-0.89), and unemployed (PR = 0.72; 95%CI 0.53-0.97). Unmet surgical needs were higher in older adults (p < 0.001), middle-class people (PR = 1.24; 95%CI 1.01-1.55), worse health statuses (p < 0.001), and chronic diseases (p < 0.001) but lower in men (PR = 0.76; 95%CI 0.65-0.86). CONCLUSIONS: From 2015 to 2019, less people visited the doctor, more were admitted to hospitals, and less were in need of surgery or aware of that need, potentially indicating poorer access to health services.

Prevalence of depressive and anxiety symptoms and their relationship with life-threatening events, tobacco dependence and hazardous alcohol drinking: a population-based study in the Brazilian Amazon.

BACKGROUND: The burden of mental health disorders is high and may be particularly alarming in developing countries. We assessed the prevalence of depressive and anxiety symptoms and their relationship with life-threatening events, tobacco dependence, and hazardous alcohol drinking in the Brazilian Amazon. METHODS: Cross-sectional population-based study conducted in Manaus in 2019 with adults selected by probabilistic sampling. Depressive symptoms were measured by the PHQ-9 instrument (cut-off ≥9) and anxiety symptoms by the GAD-7 scale (cut-off ≥10). Prevalence ratios (PRs) of depressive and anxiety symptoms were calculated by Poisson regression with robust variance with 95% confidence intervals (CI) following a hierarchical model. Partial least squares structural equation modeling was used to investigate the relationship between the outcomes and risk behaviors. RESULTS: Out of the 2,321 participants, 24.3% (95%CI 22.2-26.5%) had depressive and 21.6% (95%CI 19.6-23.7%) had anxiety symptoms. Depressive symptoms were more frequent in women (PR=1.32; 95%CI 1.08-1.61), lower social class (PR=1.59; 95%CI 1.11-2.27), life-threatening events (PR=2.66; 95%CI 2.00-3.54), tobacco dependence (PR=1.84; 95%CI 1.37-2.47), worse health statuses (p<0.001), and chronic diseases (PR=1.63; 95%CI 1.33-2.00), but were lower in older adults (p=0.014). Anxiety symptoms were higher in women (PR=1.74; 95%CI 1.42-2.14), lower educational levels (PR=2.19; 95%CI 1.38-3.47), evangelical individuals (PR=1.28; 95%CI 1.05-1.57), having no religion (PR=1.72; 95%CI 1.24-2.38), life-threatening events (PR=3.26; 95%CI 2.41-4.41), tobacco dependence (PR=1.53; 95%CI 1.09-2.16), worse health statuses (p<0.001), and chronic diseases (PR=1.77; 95%CI 1.40-2.25). Depressive symptoms, anxiety symptoms, and life-threatening events were directly correlated with one another, while tobacco dependence and hazardous alcohol drinking were significantly intercorrelated (p<0.05). LIMITATIONS: Cross-sectional design limits the assessment of causality. Recall bias was possible as responses were self-reported. GAD-7 scale was not validated in the Brazilian population. CONCLUSION: Nearly a quarter of the population had depressive symptoms and one-fifth presented anxiety symptoms, which were associated with socioeconomic, behavioral, and health-related factors. Implementation of social well-being policies is required to minimize the burden of mental health disorders in the Amazonian population.

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.

Beta-Lactams Therapeutic Monitoring in Septic Children-What Target Are We Aiming for? A Scoping Review.

The antimicrobial therapy of sepsis and septic shock should be individualized based on pharmacokinetic/pharmacodynamic (PK/PD) parameters to deliver effective and timely treatment of life-threatening infections. We conducted a literature scoping review to identify therapeutic targets of beta-lactam antibiotics in septic pediatric patients and the strategies that have been applied to overcome sepsis-related altered pharmacokinetics and increase target attainment against susceptible pathogens. A systematic search was conducted in the MEDLINE, EMBASE and Web of Science databases to select studies conducted since 2010 with therapeutic monitoring data of beta-lactams in septic children. Last searches were performed on 02 September 2021. Two independent authors selected the studies and extracted the data. A narrative and qualitative approach was used to summarize the findings. Out of the 118 identified articles, 21 met the eligibility criteria. Population pharmacokinetic modeling was performed in 12 studies, while nine studies reported data from bedside monitoring of beta-lactams. Most studies were conducted in the United States of America (n = 9) and France (n = 5) and reported PK/PD data of amoxicillin, ampicillin, azlocillin, aztreonam, cefazolin, cefepime, cefotaxime, ceftaroline, ceftazidime, doripenem, meropenem and piperacillin/tazobactam. Therapeutic targets ranged from to 40% fT> MIC to 100% fT> 6 × MIC. Prolonging the infusion time and frequency were most described strategies to increase target attainment. Monitoring beta-lactam serum concentrations in clinical practice may potentially maximize therapeutic target attainment. Further studies are required to define the therapeutic target associated with the best clinical outcomes.

Trough-guided Versus AUC/MIC-Guided Vancomycin Monitoring: A Cost Analysis.

PURPOSE: Recent vancomycin dosing and monitoring guidelines recommend monitoring vancomycin area under the 24-hour time-concentration curve instead of traditional trough-only monitoring. This study aimed to compare the total costs of vancomycin dosing and monitoring between trough-guided and AUC-guided approaches in a quaternary hospital from Brazil. METHODS: In this retrospective cohort study, patients were divided into 2 groups according to the monitoring method. Patients with previous renal impairment were excluded. Vancomycin AUC was estimated by using 2 steady-state serum concentrations and first-order kinetics equations. The primary outcome was total cost of vancomycin therapy and monitoring from the hospital perspective, which included costs of cumulative doses, laboratory fees, materials used in blood collection, nursing time for collection, and pharmacist time for result interpretation. FINDINGS: A total of 68 patients were included in the AUC/MIC-guided monitoring group, and 76 patients were included in the trough-guided monitoring group. There were no significant differences between groups regarding baseline serum creatinine level, duration of vancomycin therapy, and cumulative vancomycin dose. The median (interquartile range) total vancomycin drug and monitoring cost was $298.32 ($153.81-$429.85) for the AUC/MIC-guided group compared with $285.59 ($198.81-$435.57) for the trough-guided group (P = 0.9658). IMPLICATIONS: Vancomycin AUC estimation using 2 steady-state serum concentrations and first-order kinetics equations is a feasible alternative for limited-resource institutions that intend to transition from a trough approach to AUC/MIC-guided monitoring.

AVAILABILITY AND STORAGE OF HAZARDOUS PRODUCTS IN HOUSEHOLDS IN THE METROPOLITAN REGION OF MANAUS: A POPULATION-BASED SURVEY, 2015.

OBJECTIVE: The availability of hazardous products in households increases the risks of poisoning. The present study aimed to assess the frequency and associated factors of the availability and storage of hazardous products in residences in the metropolitan region of Manaus. METHODS: Population-based and cross-sectional study conducted in 2015 with adults selected with three-stage probabilistic sampling. Participants were interviewed face-to-face. Prevalence ratio (PR) of the presence of hazardous products (presence of chumbinho [illegal anti-cholinesterase rodenticide], artisanal cleaning products, and unsafe storage of these products and medications) and 95% confidence intervals (95%CI) were calculated with Poisson regression with robust variance, weighted by the complex sampling method adopted. RESULTS: A total of 4,001 participants was included, of which 53.0% (95%CI 51.5-54.6) reported presence of hazardous products in their households, 36.3% (95%CI 34.8-37.8) had unsafe storage, 16.2% (95%CI 15.1-17.4) had artisanal cleaning products, and 8.2% (95%CI 7.4-9.1) had chumbinho. Households with children ≤5 years old had safer storage (PR=0.78; 95%CI 0.71-0.86) and more artisanal products (PR=1.30; 95%CI 1.11-1.51). Presence of artisanal products was higher in lower educational levels (PR=2.20; 95%CI 1.36-3.57) and lower economic classifications (PR=1.63; 95%CI 1.25-2.13). CONCLUSIONS: Over half of the households in the metropolitan region of Manaus kept hazardous products; one-third stored them unsafely. Artisanal cleaning products and chumbinho were frequently present. Households with children had safer storage of products, and socioeconomic factors affected the availability of such hazardous products.

Continuity of Primary Care in the Brazilian Amazon: A Cross-Sectional Population-Based Study.

BACKGROUND: Few studies have evaluated the continuity of primary care in universal health care systems, especially in underserved areas. METHODS: This was a cross-sectional study with 4,001 adults (≥18 years old) living in the Manaus Metropolitan Region in 2015. Interviews were conducted in households selected with probabilistic sampling. City and neighborhood variables were collected from databanks. Prevalence ratios (PR) of the continuity of care (defined as using a primary care service and having been previously registered in the Family Health Strategy program) and 95% confidence intervals (CIs) were calculated with multilevel Poisson regression analysis. RESULTS: A total of 20.6% (95%CI 19.4-21.9%) of the participants reported continuity of primary care. Women (PR = 1.38; 95%CI 1.18-1.61), nonwhite individuals (PR = 1.13; 95%CI 1.05-1.21), and poorer people (PR = 1.55; 95%CI 1.19-2.02) had higher levels of continuity, whereas health insurance holders had lower levels of continuity (PR = 0.46; 95%CI 0.34-0.62). Individuals with continuity of care had more physician consultations (PR = 1.06; 95%CI 1.02-1.10), dentist consultations (PR = 1.16; 95%CI 1.05-1.28), fewer depressive (PR = 0.59; 95%CI 0.44-0.79) and anxiety symptoms (PR = 0.64; 95%CI 0.48-0.85), and a higher quality of life (ß = 0.033; 95%CI 0.011-0.054) than those without continuity. CONCLUSIONS: Continuity of care was attained by two-tenths of the population and the level of continuity was high among socioeconomically disadvantaged people. Good outcomes and health services usage increased with continuity of care.

Characteristics of Brazilian clinical studies registered in ClinicalTrials.gov between 2010 and 2020.

AIM: Evidence-based medicine uses high-quality methods, such as randomization and blinding prcedures, to support and inform clinical practice. The investigation of trials registered in clinical research databases may help understand the main characteristics of studies conducted in countries, such as Brazil. This study aimed to investigate the characteristics of Brazilian clinical trials registered in ClinicalTrials.gov in the last decade. METHODS: Cross-sectional study performed in ClinicalTrials.gov database with clinical studies registered in Brazil between 2010 and 2020. A search was conducted in the database considering this period using filters for country (Brazil), start date (01 January 2010) and end date (date of the search: 07 May 2020). Descriptive statistics were used to characterize the studies. All analyses were conducted on Stata 14.2. RESULTS: In total, 5368 studies were retrieved, which were mostly randomized (93.2%), blinded (63.2%), Phase III (48.7%) interventional studies (89.9%) with small sample sizes (57.2%) conducted with adults (93.0%) using drugs (42.7%) with a treatment purpose (77.3%), with funding from institutions other than the industry, the NIH, and the US Federal (71.3%). CONCLUSIONS: The majority of Brazilian clinical studies used blinding and randomization procedures in the last 10 years. However, the predominance of trials with small sample sizes and with a focus on adult patients indicate the need of larger studies conducted with the pediatric population.

Consumption and Lack of Access to Medicines and Associated Factors in the Brazilian Amazon: A Cross-Sectional Study, 2019.

OBJECTIVE: We aimed to investigate the consumption and lack of access to medicines in the adult population of Manaus, Amazonas. METHODS: A population-based study was conducted in Manaus in 2019. Individuals aged ≥18 years were selected by probabilistic sampling performed in three stages. Study outcomes included the consumption of medicines in the previous fortnight and the lack of access to treatments in those who used any medicine. We calculated the prevalence ratios (PR) for the outcomes with 95% confidence intervals (CI) by Poisson regression with robust variance, considering the complex sampling design. RESULTS: Out of the 2,321 participants, 53.2% (95%CI 50.7-55.7%) consumed medicines, of which 14.4% (95% CI 11.9-16.8%) could not obtain appropriate treatments. Analgesics were the most used medicines (557/2,702; 21.4%), whereas antibiotics were the most inaccessible treatments (18/228; 7.9%). Lack of financial resources was the main reason for not accessing treatments (104/228; 45.6%). Consumption was significantly associated with older age (≥60 years: PR = 1.27; 95%CI 1.09-1.49), lower social class (D/E: PR = 0.84; 95%CI 0.72-0.99), lower educational level (p = 0.039), poor health status (PR = 1.30; 95%CI 1.11-1.52), use of health care services (PR = 1.37; 95%CI 1.26-1.49), and chronic diseases (PR = 1.36; 95%CI 1.22-1.52). Lack of access was higher in people with poor health status (PR = 2.46; 95%CI 1.50-4.04) and chronic diseases (PR = 1.84; 95%CI 1.16-2.92). CONCLUSION: Half of Manaus' population used medicines, which was higher in socially privileged and sicker individuals. Among those, 14 in every 100 could not access drug therapies, which was more frequent in people with poor health and with chronic diseases.

Occupational exposures and health-related quality of life in the Manaus Metropolitan Region, Amazonas State, Brazil: a cross-sectional study.

We aimed to investigate the association between occupational exposures and health-related quality of life among both informal and formal workers in the Brazilian Amazon. We conducted a cross-sectional study with working adults in the Manaus Metropolitan Region, Amazonas State, in 2015. Participants were selected through a three-step probabilistic sampling. The primary outcome was the health-related quality of life indicator, measured by the Brazilian validated version of the European Quality of Life 5-Dimensions 3-Levels (EQ-5D-3L) tool. Adjusted multivariate analysis was performed by Tobit regression and considered the complex sampling design. Results were converted to odds ratio (OR). Out of the 1,910 working individuals from the sample, 60.2% were formal workers. Informal workers were significantly more exposed to occupational risks than formal workers (p ≤ 0.05). Mean utility score for informal and formal workers was 0.886 (95%CI: 0.881; 0.890). Quality of life of informal workers was negatively impacted by exposure to noise (OR = 1.28; 95%CI: 1.13; 1.52), occupational stress (OR = 1.95; 95%CI: 1.65; 2.21), and industrial dust (OR = 1.46; 95%CI: 1.28; 1.72), while formal workers were negatively associated with exposure to chemical substances (OR = 1.58; 95%CI: 1.28; 1.87), noise (OR = 1.40; 95%CI: 1.23; 1.65), sun (OR = 1.65; 95%CI: 1.09; 1.40), occupational stress (OR = 1.65; 95%CI: 1.46; 1.87), biological material (OR = 2.61; 95%CI: 1.72; 3.97), and industrial dust (OR = 1.46; 95%CI: 1.28; 1.65). Exposure to occupational risks among workers from the Manaus Metropolitan Region was high, affecting both informal and formal workers. Brazilian policies need to be enforced to reduce the impacts on quality of life among workers in this region.

Waiting time and medical consultation length in the Manaus metropolitan region, Brazil: a cross-sectional, population-based study, 2015. / Tempo de espera e duração da consulta médica na região metropolitana de Manaus, Brasil: estudo transversal de base populacional, 2015.

Objective . To assess waiting times and length of medical consultations in the Manaus metropolitan region, Brazil. Methods . This was a cross-sectional study conducted with adults living in the region in 2015. Waiting time for consultation and length of consultation in minutes were reported by the participants. Analysis was performed using Tobit regression and weighted by the sample design. Results . 4,001 individuals were interviewed. Average waiting time was 125.4 minutes (95%CI 120.2;130.5), while consultations lasted an average of 52.5 minutes (95%CI 48.0;57.0). Women, poor people, people with less education, indigenous people, people resident in the state interior, people without health insurance, and individuals seen by gynecologists waited longer for their consultation (p <0.05). Consultation time was shorter for non-White people, those with poor health status and those who had health insurance (p <0.05). Conclusion . On average length of medical consultations was half the waiting time. Social inequalities were observed in these lengths of time.

Seroprevalence of cytomegalovirus and its coinfection with Epstein-Barr virus in adult residents from Manaus: a population-based study.

INTRODUCTION: This study assessed the seroprevalence of cytomegalovirus, associated factors, and Epstein-Barr virus coinfection among adult residents of Manaus. METHODS: Using a cross-sectional study design, we collected blood samples from 136 individuals in a household survey in 2016. Prevalence ratios were calculated using Poisson regression. RESULTS: Cytomegalovirus and Epstein-Barr virus seroprevalences were 67.6% (95% CI: 9.7-75.6%) and 97.8% (95% CI: 95.3-100.0%), respectively. Coinfection was observed in 66.2% (95% CI: 58.1-74.2%) of participants. Bivariate analysis showed no statistical association. CONCLUSIONS: Seroprevalences were high among participants and approximately 7 out of 10 individuals had cytomegalovirus and Epstein-Barr virus coinfection.

Prevalence of self-reported dengue infections in Manaus Metropolitan Region: a cross-sectional study.

INTRODUCTION: Dengue is an endemic and epidemic disease in Brazil, with a high burden of disease. Amazonas State has a high risk of transmission. This study aimed to assess the self-reported prevalence of dengue in adults living in Manaus Metropolitan Region. METHODS: A cross-sectional study was conducted with adults living in Manaus Metropolitan Region in 2015. We performed a three-phase probabilistic sampling to collect participants' clinical and sociodemographic data. Self-reported dengue infection in the previous year was the primary outcome. Descriptive statistics and Poisson regression analysis with robust variance were used to calculate the prevalence ratio (PR) of dengue infections with 95% confidence intervals (95% CIs). Multilevel analysis including city and neighborhood variables was calculated. All analyses considered the complex sampling. RESULTS: Among the 4,001 participants, dengue in the previous year was self-reported by 7.0% (95% CI 6.3%-7.8%). Dengue was more frequent in women(PR 1.51; 95% CI 1.06-2.13), elderly participants (≥60 years old, PR 2.54; 95% CI 1.19-5.45), White and Asian participants (PR, 1.57; 95% CI, 1.11-2.23), and individuals who had not received endemic agent visits (PR, 2.28; 95% CI, 1.31-3.99). After multilevel analysis, sex was no longer a significant variable, with the remaining associations still significant. CONCLUSIONS: Seven out of 100 inhabitants of Manaus Metropolitan Region reported dengue in the previous year. Dengue was predominantly observed in women, elderly individuals, White and Asian individuals, and individuals who did not receive endemic agent visits. The setting plays an important role in dengue infections.

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.
