Association Between Deforestation and the Incidence of Snakebites in South Korea

Snakebites are a significant global health concern; despite various known risk factors, the role of environmental changes, such as deforestation, remains underexplored. Therefore, we investigated the association between deforestation and snakebite incidence in South Korea. Aggregated data were obtained from the National Health Insurance Service (NHIS) and the National Emergency Department Information System (NEDIS) from 2014 to 2021. The main explanatory variable was the level of deforestation by district and year. Additional covariates included altitude, average temperature, population size, proportion of urban land cover, proportion of agricultural land cover, and level of ecological preservation. Twelve statistical models were employed to assess the association between deforestation and snakebite incidence. The odds ratios and relative risks ranged between 1.217 and 1.452 and between 1.078 and 1.175, indicating a significant positive association between these two factors. These findings suggest that deforestation notably increases snakebite risk; collectively, our findings can help develop targeted preventive measures and healthcare strategies to reduce snakebite risk globally.

Critical evaluation of Pap test adherence to routine screening in Amazonas State, Brazil.

This study critically evaluates adherence to Pap test screening practices in cytology-based cervical cancer screening in the state of Amazonas over a 10-year period. A retrospective analysis was conducted of the results of cytological screening examinations (Pap test) in Amazonas State from 2013 to 2023. For this purpose, Brazilian public databases Cervical Cancer Information System (SISCOLO) and Cancer Information System (SISCAN) (from The Department of Information and IT of the Unified Health System - DATASUS) were consulted. There was a decrease in the number of Pap tests performed during the period from 2019 to 2021, likely related to the COVID-19 pandemic. This was followed by a subsequent increase in the post-pandemic period. Notably, in municipalities with fewer than 10,000 annual Pap examinations there was a decrease in the average number of tests when comparing the years 2016-2018 to 2013-2015, and an even greater decrease during the pandemic. There is considerable variation in utilization of the cytological Pap test across different municipalities. This lack of uniformity throughout the State likely compromises the capacity to detect early stage cervical intraepithelial lesions.

Seasonality of the incidence of bronchiolitis in infants - Brazil, 2016-2022: An interrupted time-series analysis.

To evaluate the seasonality of acute bronchiolitis in Brazil during the 2020-2022 season and compare it with the previous seasons. Data from the incidence of hospitalizations due to acute bronchiolitis in infants <1 year of age were obtained from the Department of Informatics of the Brazilian Public Health database for the period between 2016 and 2022. These data were also analyzed by macro-regions of Brazil (North, Northeast, Southeast, South, and Midwest). To describe seasonal and trend characteristics over time, we used the Seasonal Autoregressive Integrated Moving Averages Model. Compared to the pre-COVID-19 period, the incidence of hospitalizations related to acute bronchiolitis decreased by 97% during non-pharmacological interventions (March 2020 - August 2021) but increased by 95% after non-pharmacological interventions relaxation (September 2021 - December 2022), resulting in a 16% overall increase. During the pre-COVID-19 period, hospitalizations for acute bronchiolitis followed a seasonal pattern, which was disrupted in 2020-2021 but recovered in 2022, with a peak occurring in May, approximately 4% higher than the pre-COVID-19 peak. This study underscores the significant influence of COVID-19 interventions on acute bronchiolitis hospitalizations in Brazil. The restoration of a seasonal pattern in 2022 highlights the interplay between public health measures and respiratory illness dynamics in young children.

Hospitalizations, deaths, and health costs for diabetes mellitus and obesity in Acre, Brazil: A retrospective time-series study (2000 – 2021)

Introduction: Obesity and type 2 diabetes mellitus (T2DM) are among the most significant public health challenges worldwide, with profound effects on morbidity, mortality rates, and healthcare costs. Objective: The aim of this study is to evaluate the trends in deaths, hospitalizations, and hospital costs associated with T2DM and obesity in Acre, Brazil, from 2000 to 2021. Method: This retrospective time-series study utilized official microdata from the Mortality Information System, the Hospital Information System (SIH/SUS), and the Information System for Notifiable Diseases, all registered with the Ministry of Health through the SUS Department of Informatics. Data were extracted for T2DM cases between 2000 and 2021, and for obesity cases from 2013 to 2021, focusing on age, sex, and race/skin color, as well as death rates, hospitalizations, hospital costs, and municipality-level variations. Results: Our findings reveal a significant increase in T2DM-related deaths over the study period, accompanied by rising hospital costs. A higher prevalence of T2DM-related mortality was observed among older age groups, with a roughly equal distribution between men and women. For obesity, hospitalizations were more frequent after the age of 30, particularly among women. In addition, a strong correlation was found between deaths from T2DM and hospitalizations due to obesity, suggesting that many T2DM-related deaths occurred among individuals also hospitalized for obesity, a condition that often involves multiple comorbidities.

Interaction Effects Between COVID-19 Outbreak and Fever on Mortality Among OHCA Patients Visiting Emergency Departments.

Background and Objectives: Fever in patients who have suffered an out-of-hospital cardiac arrest (OHCA) has been linked to poor clinical outcomes, as a fever can exacerbate neurological damage, increase metabolic demands, and trigger inflammatory responses. This study evaluates the impact of the COVID-19 outbreak and associated fevers on OHCA outcomes and examines how they can worsen patient prognosis. Materials and Methods: Our retrospective observational analysis used data from the National Emergency Department Information System (NEDIS), comprising adult OHCA patients at 402 EDs in Korea between 27 January and 31 December 2020 (COVID-19 pandemic period) and the corresponding period in 2019 (pre-COVID-19). The primary outcome was in-hospital mortality, with the COVID-19 outbreak as the main exposure variable and fever as an important interaction variable. We employed multilevel multivariate logistic regression with an interaction term (year of visit × fever) to examine the effects of COVID-19 and fever on mortality. Risk-adjusted mortality rates were calculated, and a difference-in-difference analysis evaluated the impact of COVID-19 on excess mortality by fever status. Results: During COVID-19, in-hospital mortality was higher among OHCA patients compared to the pre-pandemic period (adjusted OR 1.22, 95% CI 1.11-1.34), particularly among febrile patients (adjusted OR 1.40, 95% CI 1.24-1.59). Interaction analysis revealed that COVID-19 disproportionately increased mortality in febrile OHCA patients compared with non-febrile patients (difference-in-difference: 0.8%, 95% CI 0.2-1.5). Conclusions: Our study found that the COVID-19 pandemic significantly increased mortality among OHCA patients, with febrile patients experiencing disproportionately worse outcomes due to systemic delays and pandemic-related disruptions.

EPIDEMIOLOGICAL TRENDS OF MENINGITIS IN BRAZIL FROM 2001 TO 2022

Introduction: Meningitis is a worldwide pathology that has a high morbidity and mortality rate. Its pathophysiology consists of an inflammation that affects the meninges, especially in the subarachnoid space, cranial and spinal segments. Materials and methods: Descriptive study that used secondary data to examine the disease "meningitis" that occurred between 2001 and 2022. The data were obtained from the Database of the Department of Information and Informatics of the SUS (DATASUS), accessible at https:/ /datasus.saude.gov.br/informacoes-de-saude-tabnet/. Results: In the years 2001-2022, 452,392 cases were reported in Brazil. The prevalence in the North region reached a total of 18,836 cases, in the Northeast 82,106, Southeast = 236,345, South = 93,353 and Central-West = 21,752, highlighting the Southeast region with the highest prevalence of cases. Discussion: The Southeast region has a higher number of meningitis cases due to the local health infrastructure and population growth in this region. Viral meningitis is one of the most relevant causes as it affects individuals of all ages, being the cause of large epidemic outbreaks and bacterial is a condition of great importance, due to its high mortality and morbidity compared to viral meningitis, the main bacterial agent is Neisseria meningitidis. Conclusion: Meningitis is a serious public health problem due to its intensity of spread and its high morbidity and mortality rate, especially in children. Therefore, it is necessary to highlight the importance of prophylactic methods such as vaccination, which are extremely effective in controlling and eradicating diseases.

Red blood cell transfusion and the use of intravenous iron in iron‐deficient patients presenting to the emergency department

AbstractBackground and aimsRed blood cell transfusions are often used to treat iron‐deficient patients in the emergency department (ED), while treatment with intravenous (IV) iron is preferred, as it increases hemoglobin concentration rapidly and durably. We aim to evaluate the incidence of iron deficiency anemia, frequency of blood transfusion and iron supplementation, and factors associated with blood transfusion in the ED.MethodsWe conducted a retrospective cohort study of adult patients presenting to the St. Boniface Hospital (Winnipeg, Canada) ED from 2014 to 2018. Electronic data obtained from the Emergency Department Information System and Laboratory Information Services databases identified patients presenting with iron deficiency anemia, defined as microcytic (mean corpuscular volume &lt; 75 fL) anemia (hemoglobin &lt; 120 g/L) with either a transferrin saturation &lt;20% or ferritin &lt; 30 µmol/L. Ferritin &gt; 100 µmol excluded iron deficiency anemia. The use of blood transfusions or iron supplementation was determined for each patient. Factors associated with blood transfusion were determined using logistic regression analyses.ResultsOf 39,222 patients, 17,945 (45%) were anemic. In anemic patients, iron parameters were ordered in 1848 (10.3%) and iron deficiency anemia was diagnosed in 910 (5.1%). Ninety‐five patients (10.4%) received one red blood cell unit, and 197 patients (21.6%) received ≥2 units. Oral iron and IV iron were prescribed for 64 (7.0%) and 14 (1.5%) patients, respectively. Hemoglobin concentration was the main determinant for treatment with blood transfusion.ConclusionsIron deficiency is underinvestigated among anemic patients presenting to the ED. The only clinical factor associated with red blood cell transfusion in the ED was hemoglobin level, irrespective of symptoms or clinical stability.

Short-Term Traffic Flow Prediction: Techniques and Methods

With the development of the economy, the expansion of the city scale, the increase in the population of urban residents and the increase in the per capita car ownership, the traffic congestion problem has an increasing impact on urban operation. Especially during the peak period of commuting traffic and holidays in large cities, most cities are facing the serious problem of road congestion. In order to facilitate the travel of residents and reduce air pollution, it is very important to keep the main road of the city smooth and rapid passage of vehicles. Therefore, cities should vigorously develop short-time traffic flow prediction, and accurate prediction of short-time traffic flow is the key to realizing intelligent urban traffic operation and efficient traffic flow management improvement. This paper will talk about the time series prediction model of short-time traffic flow prediction methods and advantages and disadvantages to provide auxiliary support for solving the traffic congestion problem, provide efficient travel path decision-making guidance for urban residents, facilitate the saving of urban people's travel costs, and also provide effective police deployment decision-making information for the traffic management department.

BCG Medac® for the treatment of non-muscle-invasive bladder tumors: adverse events and predictive factors for tolerance.

Adjuvant treatment with endovesical BCG instillations after resection of a bladder urothelial tumor remains the gold standard for intermediate- or high-risk non-muscle-invasive tumors. However, it is associated with frequent and sometimes serious adverse events (AEs). To comprehensively assess the frequency, intensity, and potential risk factors of BCG instillation AEs following the field experience of a single French center using only the Medac® BCG. A database obtained through a query to the Medical Information Department identified 127 patients who received 1498 Medac® BCG instillations from July 2016 to July 2021. The study focused on the instillations performed in the 1st year (induction treatment and the first two maintenance cycles). Data included demographics, tumor characteristics, treatment conduct and adverse events and their characteristics. Logistic regression completed the descriptive statistics to search for associations between AEs and potential risk factors. Of the 127 patients, 81% had at least one AE. AEs concerned the genitourinary sphere in 80% of cases. The proportion of side effects classified as severe was 4%. BCG treatment was discontinued in 41 patients (32.2% of patients), the main reason being the occurence of AEs (21 out of 41 patients, i.e. 51%). Age, diabetes, active smoking, previous BCG instillations, residual tumor at 2nd look TURB, use of ofloxacin and non-negative urine culture were significantly associated to AEs. Conversely, gender, previous MMC instillation, stage, grade, 2nd look procedure and ASA score were not. Multivariate analysis showed that the presence of residual tumour at 2nd look and active smoking were independent predictive factors. However, these factors were not systematically found for all instillations. The analysis was also performed per instillation. Data on a total of 1498 BCG instillations were collected, with a median of 11 instillations per patient. Of these instillations, 29.6% resulted in AEs. In addition, 125 instillations (8%) were associated with more than one AE. A total of 569 AEs were recorded, with an average of 27.2% AEs per instillation. AEs led to the postponement of 16 instillations out of 93 (17%) in 15 patients. In our study, most patients who received endovesical instillations of BCG experienced AEs, mainly localized to the genitourinary sphere and of low severity. Discontinuation of BCG and serious AEs requiring more than monitoring or symptomatic treatment were not frequent during the first year of treatment. We found no robust predictor of AEs. The problems of predicting the efficacy of BCG on the one hand, and its tolerability on the other, remain unresolved and warrant a future sufficiently powered prospective study.

Elderly patients re-transferred from long-term care hospitals to emergency departments within 48 h

Background & objectivesThe increasing proportion of elderly populations has led to a rise in chronic diseases and frequent transfers between long-term care hospitals (LTCHs) and emergency departments (EDs). This study investigates the patterns of risk factors of initial-transfers and subsequent re-transfers among patients aged 65 or older. Specifically, we focus on those re-transferred from LTCHs to EDs within 48 h of discharge, often without adequate treatment.MethodThis nationwide cross-sectional study used data from South Korea’s National Emergency Department Information System (NEDIS) from January 1, 2017, to December 31, 2019. Patients aged 65 or older who were initially transferred from LTCHs to EDs and re-transferred within 48 h, were identified. Logistic regression was employed to analyze risk factors associated with re-transfers.Results140,282 elderly patients were identified as having been transferred from LTCHs to EDs. Of these, 38,180 patients received emergency care in the EDs and were discharged back to LTCHs. Among them, 679 patients were returned to LTCHs after receiving acute treatment but revisited the EDs within 48 h. Hospital ward admission rates were higher for re-transferred patients (71.3%) compared to initial transfers (42.1%, p < 0.0001). Risk factors for re-transfer included male, nighttime admissions, and longer ED stays (> 6 h). Tertiary hospitals showed higher re-transfer rates to other facilities (13.1%) than general hospitals (2.9%).ConclusionThis study reveals that many health outcomes worsen upon re-transfer compared to the initial-transfer. These findings underscore the need for a coordinated healthcare system that ensures elderly patients from long-term care facilities are initially sent to appropriate hospitals during the initial transfer, which could mitigate repeated ED visits and ensure timely care.

Factors Affecting Technology Acceptance of Cloud Computing in ICT Departments of the Jordanian Government Hospitals

This article investigates the technological acceptance of cloud computing in the information and communications technology departments of Jordanian government hospitals. Data was collected from 165 participants (including junior, senior, and managerial staff) in 24 Jordanian hospitals in 2023. For in-depth analysis, Smart PLS 4.1.0.2 was used to evaluate the model and test the hypotheses. The results supported all hypotheses, indicating that performance expectancy, effort expectancy, social influence, cloud risks, and facilitating conditions significantly influence both the behavioral intention and use behavior of cloud computing. Finally, the findings suggest that behavioral intention of cloud computing plays a mediating role in the relationship between the predictors and actual use behavior of cloud computing.

PERFIL EPIDEMIOLÓGICO DA HANSENÍASE NO MUNICÍPIO DE ITABUNA: UMA ANÁLISE DOS ÚLTIMOS CINCO ANOS

Introduction: Leprosy is a chronic infectious disease caused by Mycobacterium leprae, primarily affecting the skin, peripheral nerves, eyes, and upper respiratory tract. Although treatable, it remains a public health challenge, especially in areas with significant social vulnerability. In Itabuna, a municipality in the interior of Bahia, data indicates a significant prevalence of the disease, highlighting the need for more effective prevention and treatment strategies. Objectives: The objective of this study is to analyze the epidemiological profile of leprosy in the municipality of Itabuna from 2019 to 2023. Justification: Leprosy remains a public health concern, especially in the most disadvantaged regions of Brazil, such as the state of Bahia. The research is justified by the need to better understand the social and epidemiological determinants of the disease.Methodology: This is an epidemiological study with a quantitative approach. Data collection was conducted using information from the Department of Informatics of the Unified Health System (DATASUS). Data on incidence, distribution of cases by age group, sex, and race, as well as temporal trends and associated risk factors, were analyzed.Results and Discussion: The data analysis revealed that between 2019 and 2023, Itabuna recorded 149 cases of leprosy, with a distribution suggesting a high prevalence among adults, particularly in the age groups of 30 to 39 years and 50 to 59 years. The incidence rate was higher among men (47%) compared to women (53%), reflecting a trend observed in other studies, although the difference was not statistically significant. Furthermore, the majority of cases were recorded among individuals of mixed race (55.7%), which may be linked to socioeconomic factors.Conclusion: This study highlights the importance of improving early diagnosis and access to treatment in order to reduce the prevalence of leprosy in Itabuna. The analysis revealed that the disease mainly affects adults in older age groups, with a predominance in men and individuals of mixed race. To reduce these rates, it is urgent to implement awareness strategies, active screening, and access to adequate treatment, along with actions aimed at improving living conditions and access to healthcare in the most vulnerable areas.

Hasn't Child Abuse Been Overlooked? An Evaluation of Abused Children Who Visited the Emergency Department with Sentinel Injuries.

Effective child abuse intervention requires understanding its prevalence. While obtaining a comprehensive national estimate of child abuse cases is challenging, sentinel injuries-minor yet unusual injuries like bruises or wounds in pre-cruising-age children-can provide an indicative measure. Using the National Emergency Department Information System (NEDIS) data, this study aimed to gauge the prevalence of sentinel injuries using diagnostic codes in children under 12 months who visited emergency centers in South Korea and to evaluate the extent of child abuse screening in these cases. This cross-sectional study used diagnostic codes indicative of sentinel injuries previously defined using the Delphi method. This study, using NEDIS data, included children under 12 months who visited emergency centers nationwide from 2014 to 2021 for reasons of injury. Children injured in car accidents were excluded. Independent variables included patient demographics, the injury mechanism, intentionality, the route of arrival, the emergency center level, the triage level, and specialist consultation. Dependent variables were the presence of a sentinel injury code, and whether diagnostic tests for child abuse were conducted. Based on NEDIS and national statistical data, the frequency from 2014 to 2021 averaged 2501 per 100,000 of the population. Of the 186,065 patients studied, 63,131 (33.9%) had a diagnostic code corresponding to a sentinel injury. The proportion of patients undergoing diagnostic tests for suspected child abuse was 36.9% for those with sentinel injuries and 43.8% for those with other codes. The percentage of children with sentinel injuries receiving diagnostic tests increased annually, from 32.4% in 2014 to 54.4% in 2021. By institution, the rates were 36.4% for regional emergency centers, 38.4% for local emergency centers, and 20.0% for local emergency institutions. A significant proportion of children presenting to emergency departments had sentinel injury codes. However, the rate of diagnostic tests conducted for suspected child abuse in these cases remains suboptimal. Although there has been an upward trend in testing rates in recent years, there is a pressing need for increased attention to and enhancement in screening for child abuse among children with sentinel injury codes.

Evolution of orthodontic services in the Brazilian Unified Health System: a time series analysis (2011–2022)

BackgroundAlthough malocclusion is the third most prevalent oral health condition, orthodontics is not part of the minimum list of mandatory specialties to be offered in the Dental Specialty Centers of the Brazilian public health system, but rather as optional. Since the acknowledgment of this field as a part of the Brazilian Unified Health System (SUS), access to orthodontic procedures has become optional by municipal governments. Therefore, this study analyzed the evolution of orthodontic procedure provision within SUS from 2011 to 2022.MethodologyWe conducted a retrospective observational study of time series analysis trends on the number of orthodontic procedures and municipalities offering them. The presentation of findings followed the recommendations of the Reporting of Studies Conducted using Observational Routinely Collected Data. Secondary data from 2011 to 2022 were collected from the SUS Department of Informatics. Orthodontic procedures were organized by year, region, state, and municipality. The study applied descriptive analyses, and the Prais-Winsten generalized linear regressions for time series analysis.ResultsThe quantity of municipalities offering orthodontic procedures have shown a small increasing during period analyzed (from 128 to 157). Northeast and South macro-regions have increased consistently the municipalities with orthodontic offering. All regions showed stable trends for each procedure, except for the South, which exhibited increasing rates of space maintainer placement (Annual Percentage Change (APC): 72.95; 95% CI: 31.6, 127.3) and maintenance sessions (APC: 15.40; 95% CI: 4.5, 27.5). The study showed decreasing trends for appliance removal in the South (APC: -38.07; 95% CI: -47.1, -27.5) and Northeast (APC: -25.19; 95% CI: -36.5, -11.9) regions.ConclusionFrom 2011 to 2022, there was a small increase in number of municipalities offering orthodontic procedures in the Brazilian public health system, in addition to a stationary trend for almost all types of procedures.

The impact of covid-19 pandemic on syphilis notifications in northeast Brazil

This study aims to evaluate the impact of the COVID-19 pandemic on the number of syphilis notifications (acquired, during pregnancy and congenital) in northeastern Brazil. An ecological study was carried out using the database provided by the Ministry of Health through the Department of Informatics of the SUS (DATASUS). The monthly numbers of notifications of acquired, gestational and congenital syphilis were organized on the Google Sheets online platform and the data were statistically analyzed, using the Wilcoxon test, for the pandemic (Jan/2020-Jun/2021) and pre pandemic periods (Jan/2018-Dec/2019), with a statistical significance of 5%. There was a reduction in the number of notifications of total cases of syphilis in the Northeast in 2020 and in 2021 when compared to the pre-pandemic period (p &lt; 0.001 and p = 0.031, respectively). This reduction represents a drop of 32.38% in 2020 and 28.84% in 2021. Regarding the states, there was no statistical significance in the number of notifications for Sergipe in 2020 (p = 0.638), Ceará in 2021 (p = 0.156) and Rio Grande do Norte in 2021 (p = 0.219) compared to 2018 and 2019. In addition, it was observed that in Sergipe there was an increase of 53.96% in notifications in 2021 compared to the same period (p = 0.031). These variations may be a consequence of social distancing, the reallocation of resources during the pandemic and socioeconomic issues, or even all of these factors combined.

Epidemiological profile of bronchial lung cancer between the years 2013 to 2023 in the northern region of Brazil

Lung and bronchial cancer is one of the leading causes of death in Brazil, with higher incidence among men, although the number of cases in women is increasing. Smoking is the main risk factor, but late diagnosis worsens disease progression, especially in marginalized regions like the North of the country. Therefore, this study aimed to analyze the evolution of lung and bronchial cancer cases in the North region of Brazil over the past ten years. Data were collected from the Department of Informatics of the Unified Health System (DATASUS) and the oncology panel, organized by age group, sex, and state. Analyses were conducted using RStudio and Excel. The state of Pará showed the highest increase in lung and bronchial cancer cases in 2023, followed by Rondônia and Amazonas, which recorded significant increases in 2021. A rise in cases was observed with advancing age, especially among men. The results suggest that delayed diagnosis, combined with the precariousness of the healthcare infrastructure in Northern Brazil, may contribute to disease progression and increased mortality. The marginalization of this region in the national healthcare context is a relevant factor in this scenario. It is concluded that delayed diagnosis and structural failures in the healthcare system are key determinants of the increase in lung and bronchial cancer cases in the North region, and that structural measures are necessary to improve early diagnosis and reduce mortality.

Institutional case volumes of thyroidectomies in Brazil and the impact of the COVID-19 pandemic: insights from a national database.

Providing widespread access to thyroidectomies while consolidating services in high-volume centers is a significant challenge in healthcare. In this context, from a national perspective, we aimed to analyze the impact of the COVID-19 pandemic on the institutional case volumes of thyroid surgery in Brazil. We analyzed retrospective thyroidectomy data from the Department of Informatics of the Unified Health System (Datasus), stratifying institutions into low-volume, intermediate-volume, and high-volume centers (<10, 10-100, and >100 thyroidectomies/year, respectively). We assessed the differences in absolute numbers and percentages of thyroidectomies performed during the pandemic years (2020-2022) compared with the pre-pandemic year (2019). Differences in the proportion of institutions based on case volumes from 2019 to 2022 were assessed using Cochran's Q test. In 2019, 556 Brazilian institutions performed 15,331 thyroidectomies. Of these, 46.4% were categorized as low-volume, 48.4% as intermediate-volume, and 5.2% as high-volume institutions, accounting for 5.5%, 61.4%, and 33.1% of the thyroidectomies, respectively. Compared with 2019, the volume of thyroidectomies was lower by 41.2% in 2020, 37.0% in 2021, and 12.8% in 2022. When analyzing the proportions of institutions that maintained their pre-pandemic case volume in the first pandemic year, the intermediate and high-volume institutions experienced reductions of 34.9% (p < 0.001) and 58.6% (p < 0.001), respectively, while low-volume institutions presented a 4.3% reduction (p = 0.081). The COVID-19 pandemic disrupted the landscape of thyroidectomies in Brazil, particularly affecting intermediate-volume and high-volume institutions, while low-volume institutions showed greater resilience.
