RESUMO
In this study, we conducted an analysis of health risks faced by residents of Salamanca, Mexico, who were exposed to fine particulate matter with a diameter of 2.5 µm (PM2.5) through inhalation. The characterization and analysis of these particulate matter samples were undertaken. A total of 131 samples were collected from two different sites: 65 from the Red Cross site (RC) and 66 from the Integral Family Development site (DIF) in 2014-2015. These samples were analyzed for a set of chemical components, including metals and ions. Non-cancerous health risk levels associated with PM2.5 exposure through the human respiratory system, as per the WHO benchmark (assigned a value of 1), revealed notable risk values for two elements: Manganese (Mn) with a range of 1.19-2.12 in the adult population and 1.59-2.84 in the child population, and Nickel (Ni) with a uniform risk value of 1.39 for both evaluated population groups. However, concerns arose regarding potential non-cancerous effects as the cumulative risk levels for various assessed elements showed elevated indices. These ranged from 3.81 to 4.4 in adults and 4.48-5.24 in children. This study provided comprehensive data on composition and its potential impact on human health, offering valuable insights for the implementation of mitigation measures aimed at reducing inhalation-related exposure.

Introduction: Low back pain can be defined as pain below the ribs and above the upper gluteal line. Objectives: The study aimed to analyze low back pain in professionals from beauty salons in the city of Fortaleza, state of Ceará. Methods: Descriptive, quantitative-qualitative, transversal, non-probabilistic research in the snowball modality, conducted between June and August 2021 in the José Walter neighborhood. Two sociodemographic questionnaires and the Quebec Back Pain Disability scale were applied, which seeks to assess how pain affects the participants' daily lives. Results: Forty-two professionals were interviewed, of which 32 women (76.2%), with a mean age of 39.45 ± 10.99 years. Women were more likely to have an onset of low back pain and to live with pain for a longer time compared to men, in addition to these professionals having a significant overload for the hours worked. 52% of respondents showed significant clinical changes, mainly in relation to stand up for 20-30 minutes (16.7%), sit in a chair for several hours (14.3%), walk several kilometers (19%), carry two bags with groceries (14.3%) and lift and carry a heavy suitcase (28.6%). Conclusions: It was evidenced that low back pain may be related to personal or environmental factors, with a sedentary lifestyle, length of service and working hours as strong indications for the onset of low back pain, with impairment in daily tasks.
Introdução: A dor lombar pode ser definida como uma dor abaixo das costelas e acima da linha glútea superior. Objetivos: Analisar a dor lombar em profissionais de salões de beleza na cidade de Fortaleza, estado do Ceará. Métodos: Tratou-se de pesquisa descritiva, qualiquantitativa, transversal, não probabilística na modalidade bola de neve, realizada entre os meses de junho e agosto de 2021 no bairro José Walter. Foram aplicados dois questionários sociodemográficos e a escala de Quebec Back Pain Disability, que busca avaliar como a dor afeta a vida diária dos participantes. Resultados: Quarenta e dois profissionais foram entrevistados, sendo 32 mulheres (76,2%), com média de idade de 39,45±10,99 anos. O sexo feminino demonstrou ter maior predisposição para o aparecimento da dor lombar, convivendo com a dor por mais tempo em relação aos homens, além dessas profissionais apresentarem uma sobrecarga significativa para as horas trabalhadas. Dos entrevistados, 52% apresentaram mudanças clínicas significativas, principalmente em relação a ficar em pé por 20 a 30 minutos (16,7%), sentar-se em uma cadeira por várias horas (14,3%), caminhar vários quilômetros (19%), carregar duas sacolas de compras (14,3%) e levantar e carregar uma mala pesada (28,6%). Conclusões: Evidenciou-se que a dor lombar pode estar relacionada a fatores pessoais ou ambientais, sendo o sedentarismo, o tempo de profissão e as horas trabalhadas fortes indícios para o aparecimento da dor lombar, com comprometimento das tarefas diárias.
RESUMO
BACKGROUND: Intensive care physiotherapists are exposed to situations that may cause physical and mental overload, which can lead to the onset of work-related musculoskeletal complaints. OBJECTIVE: The objective was to analyze these complaints and to identify activities causing greater overload, factors associated with complaints, and management and prevention strategies. METHODS: Cross-sectional study. Data were collected from 125 physiotherapists in the Intensive Care units (ICU) of a tertiary hospital. The questionnaire used was formulated from questionnaires validated in the literature such as Nordic Questionnaire and Bork Questionnaire. Chi-square test was performed to compare the groups with and without complaints. Logistic regression was used to assess the association effects of the variables on the presence of complaints. RESULTS: Of those interviewed, 76% had a work-related complaint in the last year, with the "lower back" being the most affected region. Eighty percent had complaints for more than one site. "Transfer" was considered the activity causing the greatest overload. Female sex (pâ=â0.023), lack of physical activity (pâ=â0.028), inadequate ventilation (pâ=â0.001) and inadequate furniture (pâ=â0.006) showed a statistically significant association effect with the presence of complaints. Inadequate ventilation (pâ=â0.003) and female sex (pâ=â0.004) influenced the number of affected areas. Physical activity was considered the main strategy for prevention. CONCLUSION: Musculoskeletal complaints accounted for a high percentage of the analyzed sample, mainly in the lower back. The extent of complaints suggests that strategies should be developed and changes in work dynamics should be carried out.
RESUMO
Objective To investigate the epidemiology of injury types among jiu-jitsu practitioners, as well as the incidence regarding different skill and experience levels, through the question: "What are the characteristics and prevalence of musculoskeletal injuries in Jiu-Jitsu practitioners?". Methods Since the beginning of the study, in August 2020, we conducted a search on the MEDLINE, LILACS, and SciELO electronic databases. We included cross-sectional studies published between 2018 and 2023 on the epidemiology of the types of injuries among jiu-jitsu practitioners that compared their incidence regarding different levels of ability and experience. Two independent researchers performed the data extraction and assessed the risk of bias. Results Seven studies were included. The common outcomes involved 2,847 jiu-jitsu practitioners. A high prevalence in the knee joint and chest and rib areas was reported. Considering the difference in experience level among the practitioners, we could observe that most of the individuals included were beginners. Among the age groups observed, male practitioners older than 30 years of age were the ones who presented the highest rate of musculoskeletal injury, especially during training sessions. Conclusion There is a high prevalence of musculoskeletal injuries among jiu-jitsu practitioners. The most affected anatomical segments are the knee joint, the chest, and the rib region, followed by the shoulder joint. The related factors change according to certain variables, being more common during training in male individuals over 30 years of age and beginners in the sport.
RESUMO
Background and Objectives: musculoskeletal diseases affect the musculoskeletal system and have multifactorial causes, with a higher risk of developing in some work activities. This study aimed to analyze the occurrence of musculoskeletal symptoms in Primary Health Care professionals. Methods: a comparative study among healthcare professionals from two municipalities. A structured questionnaire containing sociodemographic and professional variables and the Nordic Musculoskeletal Questionnaire were applied. Results: a total of 429 healthcare professionals have participated; 85 (19.8%) from municipality A and 344 (80.2%) from municipality B. There was no difference in the percentage of professionals with musculoskeletal symptoms between the municipalities (p>0.05). The main pain complaints in the last 12 months were for the lumbar region (56.2%), neck/cervical (48.4%), shoulders (44.7%), back/thoracic region (35.3%) and ankles/foot (31.7%). The lowest rates of pain complaints were for elbows (10.5%) and forearms (14.6%). In the last 12 months, 203 (48.7%) professionals avoided their daily activities of working, at-home service or leisure/pastime due to musculoskeletal problems/symptoms. Conclusion: Primary Health Care professionals from the studied municipalities reported main complaints of musculoskeletal symptoms, in the last 12 months, in the lumbar region, neck/cervical, shoulders, dorsal/thoracic region and ankles/foot. The regions with the fewest complaint rates were elbows and forearms. There were no significant differences in the number of professionals with complaints of musculoskeletal symptoms between the municipalities. This study provides new knowledge by contributing with information that can guide the planning and implementation of actions to promote health and prevent musculoskeletal disorders in Primary Health Care workers.(AU)

Métodos Desde o início do estudo, em agosto de 2020, foram pesquisados os bancos de dados MEDLINE, LILACS e SciELO. Foram incluídos estudos transversais, publicados entre 2018 e 2023, que investigaram a epidemiologia dos tipos de lesões ocorridas entre praticantes de jiu-jitsu e compararam sua incidência em diferentes níveis de habilidade e experiência. Para tanto, dois pesquisadores independentes realizaram a extração dos dados e avaliaram o risco de viés. Resultados Sete estudos foram incluídos. Os resultados comuns envolveram 2.847 praticantes de jiu-jitsu. Houve uma alta prevalência de lesão na articulação do joelho e nas áreas do tórax e das costelas. Considerando a diferença de nível de experiência entre os praticantes, pôde-se observar que a maioria dos indivíduos incluídos eram iniciantes. Entre as faixas etárias observadas, homens acima de 30 anos de idade foram os que mais apresentaram lesões musculoesqueléticas, principalmente durante os treinos. Conclusão Houve uma alta prevalência de lesões musculoesqueléticas entre os praticantes de jiu-jitsu. Os segmentos anatômicos mais acometidos foram a articulação do joelho, o tórax e a região das costelas, seguidos da articulação do ombro. Os fatores relacionados mudaram de acordo com algumas variáveis, sendo mais comuns durante o treinamento em indivíduos do sexo masculino com mais de 30 anos e iniciantes na modalidade.
RESUMO
OBJECTIVES: To better understand variations in multimorbidity severity over time, we estimate disability-free and disabling multimorbid life expectancy (MMLE), comparing Costa Rica, Mexico, and the United States (US). We also assess MMLE inequalities by sex and education. METHODS: Data come from the Costa Rican Study on Longevity and Healthy Aging (2005-2009), the Mexican Health and Aging Study (2012-2018), and the Health and Retirement Study (2004-2018). We apply an incidence-based multistate Markov approach to estimate disability-free and disabling MMLE and stratify models by sex and education to study within-country heterogeneity. Multimorbidity is defined as a count of 2 or more chronic diseases. Disability is defined using limitations in activities of daily living. RESULTS: Costa Ricans have the lowest MMLE, followed by Mexicans, then individuals from the US. Individuals from the US spend about twice as long with disability-free multimorbidity compared with individuals from Costa Rica or Mexico. Females generally have longer MMLE than males, with particularly stark differences in disabling MMLE. In the US, higher education was associated with longer disability-free MMLE and shorter disabling MMLE. We identified evidence for cumulative disadvantage in Mexico and the US, where sex differences in MMLE were larger among the lower educated. DISCUSSION: Substantial sex and educational inequalities in MMLE exist within and between these countries. Estimating disability-free and disabling MMLE reveals another layer of health inequality not captured when examining disability and multimorbidity separately. MMLE is a flexible population health measure that can be used to better understand the aging process across contexts.

OBJECTIVE: To determine the individual learning curves for cordocentesis in a low-cost simulator for maternal-fetal medicine (MFM) fellows. METHODS: This observational, descriptive, educational, and prospective study was performed from July through November 2022. After an introductory course based on a standardized technique for cordocentesis, each second-year MFM fellow who accepted to participate in the study performed this procedure using a low-cost simulation model, and experienced operators supervised the cordocenteses. Learning curves were then created using cumulative sum analysis (CUSUM). RESULTS: Seven second-year MFM fellows with no previous experience in cordocentesis accepted to participate in the study. A total of 2676 procedures were assessed. On average, residents performed 382 ± 70 procedures. The mean number of procedures to achieve proficiency was 369 ± 70, the overall success rate was 84.16%, and the corresponding failure rate was 15.84%. At the end of the study, all fellows were considered competent in cordocentesis. One fellow required 466 attempts to achieve competency, performing a total of 478 procedures, but the resident with the fewest attempts to reach competency required 219 procedures, completing 232 procedures. Some of the most frequent reasons for failed attempts included not reaching the indicated point for vascular access (20.99%) and being unable to retrieve the sample (69.10%). CONCLUSION: CUSUM analysis to assess learning curves, in addition to using low-cost simulation models, helped to appraise individualized learning, allowing an objective demonstration of competency for cordocentesis among MFM fellows.

BACKGROUND: Dockworkers are exposed to physical overloads that can contribute to the development of musculoskeletal disorders, leading to functional disability and absenteeism. OBJECTIVE: to map, critically appraise, and synthesize the available evidence on the prevalence of musculoskeletal diseases associated with port occupational activities. METHODS: A comprehensive search was conducted in structured and unstructured databases in August 2023, with no date or language restriction, to identify observational studies evaluating the prevalence of musculoskeletal disorders in dockworkers' occupational activity. The risk of bias was assessed using validated tools based on the included study designs. Data from studies were pooled in meta-analyses. The certainty of the evidence was assessed using the GRADE approach. RESULTS: We identified 12 analytical cross-sectional studies involving 7821 participants in ports of five countries. Most studies (75%) had a moderate methodological quality according to the Joanna Briggs Institute tool. Considering the overall worker categories and any musculoskeletal disorders, the meta-analysis showed a prevalence of 58% (95% Confidence Interval [95% CI] 37% to 78%), with degenerative spinal diseases 42% (95% CI -0.6% to 91%) and low back pain 36% (95% CI 21% to 50%) being the most prevalent conditions. Symptoms were predominantly in foremen and stevedores. The certainty of the evidence was very low. CONCLUSIONS: Musculoskeletal disorders seem prevalent among dockworkers, mainly degenerative spinal diseases and low back pain. Studies with greater methodological consistency are still needed to validate these hypotheses and assist in decision-making for implementing preventive and informational policies in maritime port management organizations.

This study aimed to investigate alternative approaches to a cumulative risk score in the relationship between adverse childhood experiences (ACEs) and crime. Using data from the 1993 Pelotas (Brazil) Birth Cohort (n = 3236), we measured 12 ACEs up to 15 years, and past-year violent and non-violent crime at 22 years. We used four analytical approaches: single adversities, cumulative risk, latent class analysis, and network analysis. When examined individually, physical abuse, emotional abuse, and domestic violence were associated with both crime outcomes, whereas maternal mental illness and discrimination were associated with violent crime only, and parental divorce and poverty with non-violent crime only. There was a cumulative effect of ACEs on crime. The class with child maltreatment and household challenges was associated with both crime outcomes; exposure to household challenges and social risks was associated with violent crime only. In network models, crime showed conditional associations with physical abuse, maternal mental illness, and parental divorce. Although cumulative ACEs did associate with crime, some individual and combinations of ACEs showed particularly strong and robust effects, which were not captured by the cumulative score. Many ACEs are closely connected and/or cluster together, and the usefulness of the ACE score needs to be further evaluated.

Predictors of health across the life-course do not maintain the same significance in very late life and the role of financial strain in health outcomes of very old adults remain unclear. Data from adults aged 74 + in waves 5 and 7 of the Hispanic Established Population for the Epidemiological Study of the Elderly (n = 772) study was used to evaluate the role of financial strain on the health of older Mexican Americans who have the highest poverty rate of any racial or ethnic group in the United States. We evaluate the association between episodic (one wave) and persistent financial strain (two waves), with follow-up health outcomes (self-rated health, ADL (limitations in activities of daily living)/IADL (limitations in instrumental activities of daily living) disability, and depressive symptoms). Adults with persistent strain were twice as likely to experience depressive symptoms and three times more likely to experience IADL limitations than the unstrained. Our findings highlight the role of stress proliferation and allostatic load processes leading to deteriorated health over time.

ABSTRACT This aimed to systematically review randomized controlled trials and compare the effectiveness of labor gymnastics with that of no intervention, minimal intervention or other types of intervention in healthcare workers, in relation to musculoskeletal pain, stress, physical disability, and absence from work. A search was carried out in the PUBMED, Pedro, EMBASE, CENTRAL, CINAHAL, PSYCHINFO, NIOSHTIC-2, SPORT DICUS, SCIELO, and LILACS databases. In total, 3,598 articles were found, seven of which were eligible for the study. There was a statistical difference in musculoskeletal pain in favor of labor gymnastics after 5, 10 and 12 weeks (MD: −0.63; 95%, CI: −1.17; −0.08) and 6, 9 and 12 months of intervention (MD: −0.74; 95% CI: −1.43; −0.05). There was also a statistical difference in favor of labor gymnastics in terms of time off work (MD: −3.26; 95% CI: −6.28; −0.25) and stress (SMD: −0.35; 95% CI: −0.67; −0.03) in studies in which interventions were carried out for 5 and 10 weeks. Labor gymnastics can contribute to the physical and mental health of healthcare professionals. However, more randomized controlled studies with a larger sample size and aimed at this professional category are needed.
RESUMEN Este estudio tuvo por objetivo realizar una revisión sistemática de los ensayos aleatorizados controlados y comparar la efectividad de la gimnasia laboral con ninguna intervención, con intervención mínima u otros tipos de intervención en los profesionales de la salud con relación a dolor musculoesquelético, estrés, incapacidad física y baja laboral. Se realizaron búsquedas en las bases de datos PUBMED, PEDro, EMBASE, CENTRAL, CINAHAL, PsycINFO, NIOSHTIC-2, SPORTDicus, SciELO y LILACS. Se encontraron 3.598 artículos, de los cuales siete fueron elegibles. Hubo una diferencia estadística para el dolor musculoesquelético a favor de la gimnasia laboral después de 5, 10 y 12 semanas (MD: −0,63; 95% CI: −1,17; −0,08) y 6,9 y 12 meses de intervención (MD: −0,74; 95% CI: −1,43; −0,05). También hubo una diferencia estadística a favor de la gimnasia laboral para el tiempo de baja laboral (MD: −3,26; 95% IC: −6,28; −0,25) y la reducción del estrés (SMD: −0,35; 95% IC: −0,67; −0,03) en los estudios que realizaron la intervención entre cinco y diez semanas. La gimnasia laboral puede contribuir a la salud física y mental de los profesionales de la salud, sin embargo, son necesarios más estudios aleatorizados controlados dirigidos a esta categoría profesional y con un mayor tamaño muestral para confirmar esta hipótesis.
RESUMO Este estudo tem como objetivo revisar sistematicamente ensaios randomizados controlados e comparar a eficácia da ginástica laboral com nenhuma intervenção, intervenção mínima ou outros tipos de intervenção em trabalhadores de saúde, em relação à dor musculoesquelética, estresse, incapacidade física e afastamento do trabalho. Foram realizadas buscas nas bases de dados PUBMED, PEDro, EMBASE, CENTRAL, CINAHAL, PsycINFO, NIOSHTIC-2, SPORTDicus, SCIELO e LILACS. Foram encontrados 3598 artigos, sendo sete elegíveis. Houve diferença estatística para dor musculoesquelética a favor da ginástica laboral após 5, 10 e 12 semanas (MD: −0,63; 95%, CI: −1,17; −0,08) e 6,9 e 12 meses de intervenção (MD: −0,74; 95% CI: −1,43; −0,05). Também foi verificada diferença estatística a favor da ginástica laboral para o afastamento no trabalho (MD: −3,26; 95% IC: −6,28; −0,25) e para redução do estresse (SMD: −0.35; 95% IC: −0,67; −0.03) nos estudos que realizaram intervenção por 5 e 10 semanas. A ginástica laboral pode contribuir para a saúde física e mental do profissional de saúde, no entanto, mais estudos randomizados controlados voltados para essa categoria profissional, e com maior valor amostral, são necessários para confirmação dessa hipótese.
RESUMO
Resumo Objetivo: investigar os efeitos de intervenções no ambiente laboral para prevenção de distúrbios musculoesqueléticos. Métodos: revisão sistemática que incluiu ensaios randomizados, individuados ou comunitários, que investigaram efeitos de intervenções no trabalho para prevenir distúrbios musculoesqueléticos, relatados em artigos publicados entre 2015 e 2020 e indexados nas bases de dados: Lilacs, Medline/Pubmed, PEDro e Web of Science. Os estudos foram categorizados conforme a modalidade de intervenção e avaliados quanto à qualidade metodológica. Resultados: dos 58 estudos selecionados, 15 atenderam satisfatoriamente aos critérios de qualidade, abordando diferentes modalidades de exercícios físicos e/ou abordagem cognitivo-comportamental, aplicadas de forma única ou combinada; nenhum estudo abordou intervenções organizacionais. Apesar da heterogeneidade de intervenções e desfechos, exercícios físicos realizados nos locais de trabalho resultaram em diminuição da dor musculoesquelética, do uso de analgésicos e do afastamento do trabalho por distúrbios musculoesqueléticos, no entanto, combinados às intervenções comportamentais não mostraram os resultados esperados. Os resultados com a Ergonomia Participativa ratificaram o papel fundamental dos trabalhadores na realização de intervenções em seus ambientes de trabalho. Conclusão: apesar de benefícios observados, salienta-se que os estudos revisados não produziram evidências consolidadas acerca das intervenções mais eficazes para prevenir distúrbios musculoesqueléticos entre trabalhadores.
Abstract Objective: to investigate the effects of workplace interventions aiming to prevent musculoskeletal disorders. Methods: systematic review that included randomized, individual or community trials, which investigated the effects of workplace interventions aiming to prevent musculoskeletal disorders, reported in articles published between 2015 and 2020 and indexed in the following databases: Lilacs, Medline/Pubmed, PEDro, and Web of Science. Studies were categorized according to the type of intervention and evaluated in terms of methodological quality. Results: of all 58 studies selected, 15 satisfactorily met the quality criteria, addressing different types of physical exercise and/or cognitive-behavioral approaches, applied alone or in combination. No study addressed organizational interventions. Despite the heterogeneity of interventions and outcomes, physical exercises performed in the workplace led to reduction in musculoskeletal pain, use of analgesics, and absence from work due to musculoskeletal disorders; however, combined with behavioral interventions, they did not show the expected results. The results with participatory ergonomics confirmed the critical role of workers in performing interventions in the workplace. Conclusion: despite the benefits observed, the studies reviewed did not produce consolidated evidence about the most effective interventions to prevent musculoskeletal disorders among workers.

Introduction: Repetitive Strain Injuries/Work-Related Musculoskeletal Disorders represent a health problem that affects several categories of workers and are related to work organization, work environment, environmental conditions and biopsychosocial factors. Objective: to describe the reported cases of Repetitive Strain Injuries/Work-Related Musculoskeletal Disorders in the Northeast Region of Brazil (2010 2019).Methodology: descriptive, cross-sectional study with a quantitative approach, with secondary data from the Information System for Notifications of Diseases. The Statistical Package for Social Sciences software version 20 was used for the descriptive statistical analysis and the Qgis software version 3.10.7 for the spatial analysis. Results:The sample consisted of 14,484 notifications. Brazilian states as Bahia 42,0% and Pernambuco 21.9% registered more notifications. Moreover, municipalitiesas Salvador 15,2% and Recife 11,5% registered more cases. It was observed that the spatial distribution of cases of this condition among municipalities is uneven and concentrated. The most affected workers were women (59.6%); aged between 21 and 40 years (50.8%), with black/brown race/color (58.3%) and with complete secondary education (42.0%). There was a predominance of the occupation of production line feeder (4.8%), formal work (74.6%), pain symptom (91.9%) anddiagnosis of shoulder injuries (31.7%). Most workers reported absence from work for treatment (65.3%), limitation and inability to perform tasks (82.9%), performing repetitive movements (88.3%) and temporary disability (66.1 %). Conclusions: System for Notifications of Diseases represents an important instrument to characterize the health of workers, but there is a need for better records to favor data quality. Studies in this sense are needed to support more surveillance and prevention actions for this condition (AU).

Our objectives were to evaluate the use of cottonseed cake in replacing corn silage in a diet without forage and to identify the model with higher precision and accuracy of adjustment of parameters of ruminal degradation kinetics. A diet containing corn silage and another with cottonseed cake as a fiber source were formulated. Gompertz, Dual-pool Logistic, Brody, and Ørskov models were evaluated for goodness of fit to gas production. There were significant differences in dry matter (DM), organic matter (OM), and neutral detergent fiber (NDF) in the in vitro digestibility for diets and fiber sources. The estimated values of the Gompertz (6.77), Brody (6.72), and Ørskov (6.73) models were similar to the observed mean of gas production in the corn silage diet (6.73 mL/100 mg DM). Similarly, the estimated values of the Brody (5.87) and Ørskov (5.89) models were similar to the observed mean of gas production in the cottonseed cake diet (5.87 mL/100 mg DM). The roughage-free diet containing cottonseed cake as a fiber source stimulated higher gas production. Brody and Ørskov models presented higher precision and accuracy in the fitting of kinetics of degradation independent of the fiber source in the diet.
RESUMO
Background: The true incidence of SARS-CoV-2 infection in Costa Rica was likely much higher than officially reported, because infection is often associated with mild symptoms and testing was limited by official guidelines and socio-economic factors. Methods: Using serology to define natural infection, we developed a statistical model to estimate the true cumulative incidence of SARS-CoV-2 in Costa Rica early in the pandemic. We estimated seroprevalence from 2223 blood samples collected from November 2020 to October 2021 from 1976 population-based controls from the RESPIRA study. Samples were tested for antibodies against SARS-CoV-2 nucleocapsid and the receptor-binding-domain of the spike proteins. Using a generalized linear model, we estimated the ratio of true infections to officially reported cases. Applying these ratios to officially reported totals by age, sex, and geographic area, we estimated the true number of infections in the study area, where 70% of Costa Ricans reside. We adjusted the seroprevalence estimates for antibody decay over time, estimated from 1562 blood samples from 996 PCR-confirmed COVID-19 cases. Findings: The estimated total proportion infected (ETPI) was 4.0 times higher than the officially reported total proportion infected (OTPI). By December 16th, 2021, the ETPI was 47% [42-52] while the OTPI was 12%. In children and adolescents, the ETPI was 11.0 times higher than the OTPI. Interpretation: Our findings suggest that nearly half the population had been infected by the end of 2021. By the end of 2022, it is likely that a large majority of the population had been infected. Funding: This work was sponsored and funded by the National Institute of Allergy and Infectious Diseases through the National Cancer Institute, the Science, Innovation, Technology and Telecommunications Ministry of Costa Rica, and Costa Rican Biomedical Research Agency-Fundacion INCIENSA (grant N/A).
RESUMO
Purpose: To determine the energy expenditure in phacoemulsification surgery expressed as cumulative dissipated energy (CDE) among the divide and conquer, ultrachopper-assisted divide and conquer, and phaco-chop techniques for dense cataract removal. Patients and Methods: The clinical data were obtained from the medical charts of dense cataracts patients undergoing routine phacoemulsification employing any of three phaco-fragmentation techniques, including divide and conquer using the Kelman 0.9 mm tip, the ultrachopper tip, and the phaco-chop technique using the Kelman 0.9 mm tip. Cumulated dissipated energy (CDE), longitudinal ultrasound time (UST), and endothelial cell loss were compared among groups at the one-month postoperative. Results: Surgeries from 90 eyes were analyzed, among whom the conventional divide-and-conquer technique group included 30 patients, 32 in the ultrachopper group, and 28 in the phaco-chop technique group. The average CDE in the conventional divide and conquer group was 44.52 ± 23.00, the ultrachopper technique was 43.27 ± 23.18, and 20.11 ± 11.06 in the phaco-chop group. Phaco-fragmentation chop demonstrated significantly lower CDE than the other techniques (p= <0.0001). The phaco-chop technique showed statistically significantly lower CDE when compared to the other two groups (p=<0.0001) with 93.96 ± 39.71 seconds. There were no statistically significant differences in postoperative endothelial cell density between groups (p=0.4916). Conclusion: The use of the phaco-chop technique in hard cataract phacoemulsification represents a lower energy expenditure than divide and conquer and ultrachopper techniques; nevertheless, no differences regarding endothelial density loss were evidenced.
RESUMO
BACKGROUND: Studies investigating vulnerable populations have shown that work-related musculoskeletal disorders have a negative impact on quality of life. However, no study has examined the body regions commonly affected by work-related musculoskeletal disorders in vulnerable populations. OBJECTIVE: To describe the body regions commonly affected by work-related musculoskeletal disorders in vulnerable populations. METHODS: Cross-sectional study. We used the ABEP questionnaire, the World Health Organization Quality of Life, the Nordic Musculoskeletal Disorders Questionnaire, the Perceived Stress Scale, and a self-report questionnaire to determine morning-evening in human circadian rhythms (chronotype assessment). To reduce the possibility of information bias, we provided prior training in the use of the instruments and created an electronic database that was filled out in duplicate (in cases of disagreement, a third researcher was consulted). We tested the normality of the data using the Shapiro-Wilk test. RESULTS: The sample consisted of 132 participants, but there was a sample loss of 41.6% (final sample n = 77). We observed the predominance of those who worked from 6 to 8 h/day, rest of 1 h during the working day, from 1 to 10 years of service and only 1 employment relationship. Regarding the quality of life, we observed a worse result in the domain related to the environment, as well as a stress level of 15.43 (± 7.52) with a maximum of 30. Finally, we observed the presence of pain self-reported by the artisanal fishermen in several regions of the body, lumbar being the most mentioned. CONCLUSION: The neck, shoulders, arms, elbows, forearms, wrists, back, lumbar spine, and lower limbs are the most common parts of the body affected by work-related musculoskeletal disorders in artisanal fishermen.

Objective To investigate the long-term use of smartphones as a risk factor for the development of morbidities in the wrist and fingers. Methods The present is a descriptive, exploratory study with a quantitative approach based on injury prevalence among one hundred smartphone users of a private university in the state of Pernambuco, Northeastern Brazil. We applied a semi-structured questionnaire and the Boston Carpal Tunnel Questionnaire (BCTQ), as well as the Visual Analog Scale (VAS) and the Finkelstein, Phalen, reverse Phalen, and Tinel signal tests on the wrist. Results The average of the sample was of 22.73 years, with a prevalence of single, right-handed female participants. Most of them had been using smartphones for 5 to 10 years, and 85% reported discomfort in the wrist and fingers while using the device, with numbness as the most prevalent symptom. Most clinical tests were negative, and the Finklestein test showed greater positivity. The BCTQ is composed of a symptom severity scale (S scale) and a functional status scale (F scale): the overall score on the S scale was of 1.61, indicating mild to moderate symptoms, and the F scale revealed that the symptoms did not affect functionality. Conclusion There was a significant correlation between the length of use of smartphones and discomfort in the wrist and fingers; as such, smartphones are a risk factor for the development of morbidities.
