Do predator attacks on productive species and the respective economic losses influence the psychological distress of farmers in Uruguay? A cross-sectional study.

INTRODUCTION: In Uruguay, productive animals are attacked by various predators, causing injuries and financial losses, leading to great concern for farmers. The objective of this study was to determine, using a cross-sectional study, if predator attacks on productive animals during the year 2021 influenced the psychological distress of farmers. METHODS: Four hundred and forty-two farmers from around the country were surveyed with questions according to the Kessler Psychological Distress Scale (dependent variable), and predator attacks received in 2021 (independent variable). RESULTS: Of the total number of farmers surveyed, approximately 49% (216/442) had animals that had been attacked by predators. Farmers whose productive species were attacked in 2021 had higher levels of psychological distress than those whose animals were not attacked (p<0.01). Additionally, farmers who reported the highest levels of psychological distress had more deaths of productive species (and more financial losses) from predator attacks in 2021 than those who did not. CONCLUSION: The losses of productive species and the financial costs negatively influenced the psychological distress of farmers. This information highlights the need to generate public policies about farmers wellbeing that help them in these situations.

Genomic and eco-epidemiological investigations in Uruguay reveal local Chikungunya virus transmission dynamics during its expansion across the Americas in 2023.

Uruguay experienced its first Chikungunya virus outbreak in 2023, resulting in a significant burden to its healthcare system. We conducted analysis based on real-time genomic surveillance (30 novel whole genomes) to offer timely insights into recent local transmission dynamics and eco-epidemiological factors behind its emergence and spread in the country.

LAENALS: epidemiological and clinical features of amyotrophic lateral sclerosis in Latin America.

OBJECTIVE: The Latin American Epidemiologic study of ALS (LAENALS) aims to gather data on ALS epidemiology, phenotype, and risk factors in Cuba, Chile, and Uruguay, to understand the impact of genetic and environmental factors on ALS. METHODS: A harmonized data collection protocol was generated, and a Latin-American Spanish language Register was constructed. Patient data were collected in Uruguay in 2018, in Chile from 2017 to 2019, and in Cuba between 2017 and 2018. Statistical analysis was performed using SPSS 25.0.0 software. Crude cumulative incidence, standardized incidence, and prevalence were calculated in the population aged 15 years and older. RESULTS: During 2017-2019, 90 people with ALS from Uruguay (55.6% men), 219 from Chile (54.6% men), and 49 from Cuba (55.1% men) were included. The cumulative crude incidence in 2018 was 1.73/100,000 persons in Uruguay, 1.08 in Chile and 0.195 in Cuba. Crude prevalence in 2018 was 2.19 per 100,000 persons in Uruguay, 1.39 in Chile and 0.55 in Cuba. Mean age at onset was 61.8 ± 11.96 SD years in Uruguay, 61.9 ± 10.4 SD years in Chile, and 60.21 ± 12.45 SD years in Cuba (p = 0.75). Median survival from onset was 32.43 months (21.93 - 42.36) in Uruguay, 24 months (13.5 - 33.5) in Chile, and 29 months (15 - 42.5) in Cuba (p = 0.006). CONCLUSIONS: These preliminary data from LAENALS confirm the lower incidence and prevalence of ALS in counties with admixed populations. The LAENALS database is now open to other Latin American countries for harmonized prospective data collection.

Seroprevalence and herd-level associated factors of pathogenic Leptospira spp. circulating locally in dairy cattle in Uruguay.

Leptospirosis is a zoonotic disease of worldwide importance. In Uruguay, it is endemic in cattle and primarily affects people with occupational exposure to livestock. The aim of this study was to determine the national seroprevalence and associated factors of local pathogen Leptospires in dairy cattle. A cross-sectional study was carried out. Herds were stratified by size (1-50, 51-250, and > 250 cattle), and up to 60 dairy cows per herd were randomly selected. A total of 4269 serum samples from 101 dairy herds were analyzed by microscopic agglutination test (MAT). A two-stage sampling design was used to estimate population seroprevalence of Leptospira spp. In order to determine the factors associated with the disease, herds with at least 1 seropositive animal were considered as case herds. Seroprevalence of Leptospira was 27.80% with a 95% CI [21.06, 34.54] at the animal level and 86.92% with a 95% CI [80.00, 93.75] at the herd level. The serology confirms the predominance of serogroups Sejroe and Pomona in our herd with the presence of incidental leptospires infection, in smaller proportion, but with a wide distribution at farm level. The population size and purchasing replacement of cows on dairy farms were associated with infection at farm level. The serologic studies confirmed that exposure to Leptospira spp. is endemic in our herds, and the spreading over dairy herds. Although the movement of purchased females and the size of the herd were associated with the disease, more studies should be conducted, to better understand the epidemiology of the disease and to highlight the possible risks to public health, especially in rural workers, farmers and veterinarians.

Secular trends in blood lead concentrations of school-age children in Montevideo, Uruguay from 2009 to 2019.

Lead exposure continues to be a public health problem globally, yet very few countries perform systematic biomonitoring or surveillance of children's blood lead levels (BLLs). Secular trends in children's BLLs have not been well characterized outside North America and Europe. In 2009-19, we conducted a series of non-representative cross-sectional surveys in Montevideo, Uruguay, enrolling children living in areas of the city with known or suspected lead contamination. Lead was measured with atomic absorption spectrometry on fasting venous blood samples. Of the 856 children representing independent (non-sibling) observations, 759 had BLL measures. Other missing data were imputed. Using linear and logistic regression models, we estimated the covariate-adjusted year to year difference in mean BLL and the likelihood of having BLL ≥5 and BLL ≥3.5 µg/dL. At the start of the study, mean ± SD BLL was 4.8 ± 2.6 µg/dL, and at the end 1.4 ± 1.4 µg/dL. The prevalence of BLL ≥5 and BLL ≥3.5 µg/dL also differed markedly between 2009 and 2019 (30.8% vs. 2.7% and 53.8% vs. 5.8%). Similarly, where 80.8% of children had BLL ≥2 µg/dL in 2011, in 2019 that number was 19.3%. The estimated year to year difference in BLL was ∼0.3 µg/dL. Despite this progress, pediatric lead exposure remains a problem in Montevideo. In years 2015-19, between 19 and 48% of school children had BLL ≥2 µg/dL, a level at which adverse neurobehavioral outcomes continue to be reported in the literature. Continued prevention and risk-reduction efforts are needed in Montevideo, including systematic surveillance of BLLs in all children.

Clinical signs associated with prostatic disorders in canines: Retrospective study in Uruguay (2011-2019).

Background: Prostate disease represents about 0.7% of diseases in canines. The main diagnosed pathology is benign prostatic hyperplasia (BPH). However, the reports that study the association of a certain clinical sign with a specific prostate disease are scarce. Aim: The main objective of this study was to evaluate the clinical relevance of the most commonly observed clinical signs associated with the different prostatic disorders in canines admitted to the hospital of the Facultad de Veterinaria-Universidad de la República between 2011 and 2019. Methods: This retrospective study included 7,729 male canines treated at the hospital de la Facultad de Veterinaria-Universidad de la República (Montevideo, Uruguay) between 2011 and 2019. 289 canines with a presumptive/definitive diagnosis of prostate diseases were selected, recording the presence/absence of associated clinical signs. Results were reported in terms of odds ratios (ORs) using logistic regression (p < 0.05). Results: The five most frequently reported clinical signs were tenesmus (34%), anorexia (32%), lethargy (27%), prostatomegaly or pain during rectal examination (25%), and abdominal pain from palpation (22%). Diarrhea (3.39 vs. 0.33 OR), anorexia (2.07 vs. 0.39 OR), weight loss (2.27 vs. 0.27 OR), hematuria (3.25 vs. 0.44 OR), and urinary incontinence (2.96 vs. 0.33 OR) indicated a highest predictive value (p < 0.05) with prostatitis versus BPH, respectively. Being weight loss, the clinical sign is more frequently associated with neoplasia (20.2 OR, p = 0.002). Conclusion: This study shows that there are clinical signs with a higher degree of association for certain canine prostatic disorders than others.

Epidemiology Update of Hepatitis E Virus (HEV) in Uruguay: Subtyping, Environmental Surveillance and Zoonotic Transmission.

Hepatitis E Virus (HEV) infection is an emergent zoonotic disease of increasing concern in developed regions. HEV genotype 3 (HEV-3) is mainly transmitted through consumption of contaminated food in high-income countries and is classified into at least 13 subtypes (3a-3n), based on p-distance values from complete genomes. In Latin America, HEV epidemiology studies are very scant. Our group has previously detected HEV3 in clinical cases, swine, wild boars, captive white-collared peccaries, and spotted deer from Uruguay. Herein, we aimed to provide novel insights and an updated overview of the molecular epidemiology of zoonotic HEV in Uruguay, including data from wastewater-based surveillance studies. A thorough analysis of HEV whole genomes and partial ORF2 sequences from Uruguayan human and domestic pig strains showed that they formed a separate monophyletic cluster with high nucleotide identity and exhibited p-distance values over the established cut-off (0.093) compared with reference subtypes' sequences. Furthermore, we found an overall prevalence of 10.87% (10/92) in wastewater, where two samples revealed a close relationship with humans, and animal reservoirs/hosts isolates from Uruguay. In conclusion, a single, new HEV-3 subtype currently circulates in different epidemiological settings in Uruguay, and we propose its designation as 3o along with its reference sequence.

Molecular Characterization of Gastroenteric Viruses in Wastewater from Cities in Uruguay.

Group A Rotavirus, Human Astrovirus, and Norovirus (RVA, HAstV, and NoV) are recognized as the major causative agents of acute gastroenteritis in children and adults worldwide. The aim of this study was to determine the prevalence and molecular epidemiology of RVA, HAstV, and NoV in wastewater from three cities in Uruguay. Thirty-six samples from Bella Unión, Salto, and Fray Bentos cities were analyzed using quantitative and qualitative PCR. RVA was the most frequently detected virus (50%), followed by HAstV (39%), NoV GII (36%), and NoV GI (25%). RVA strains were characterized as P[8] and G3 based on the VP4 and VP7 genes, respectively. Among NoV-positive samples, genotypes GI.2, GI.3, GI.5, GI.6, GI.7, GII.2, GII.6, and GII.4 were detected, and only one HAstV genotype (MLB1) was found. Our wastewater-based epidemiological approach provides a snapshot of the overall genetic diversity of these viruses in three cities of the Uruguay River basin during 2017-2018. These findings reinforce the importance of this environmental surveillance tool for monitoring epidemiological trends of enteric viruses circulating in the population, which can be used to guide public health intervention.

Spreading of the High-Pathogenicity Avian Influenza (H5N1) Virus of Clade 2.3.4.4b into Uruguay.

BACKGROUND: Avian influenza viruses (genus Alphainfluenzavirus, family Orthomyxoviridae) infect avian and mammal hosts. In 2022, the high pathogenicity avian influenza virus (H5N1) spread to South America, resulting in the loss of thousands of wild birds, including endangered species, and severely impacting the global poultry industry. OBJECTIVES: We analyzed the complete genomes of influenza viruses obtained from wild birds and backyard poultry in Uruguay between February and May 2023. METHODS: Twelve complete genomes were obtained in 2023 from cloacal swabs using Illumina sequencing. Genomes were phylogenetically analyzed with regional and global strains. FINDINGS: The identified strains have multiple basic amino acids at the hemagglutinin cleavage sites, which is typical for highly pathogenic strains. The Uruguayan viruses belonged to hemagglutinin clade 2.3.4.4b of the H5N1 subtype. A reassortment in North America has resulted in some segments of South American strains being of Eurasian or North American origins. The Uruguayan viruses shared a common ancestor with South American strains from Argentina and Chile. The influenza viruses displayed a spatiotemporal divergence pattern rather than being host-specific. MAIN CONCLUSIONS: The arrival of the 2.3.4.4b clade in Uruguay may have been mediated by birds that acquired the virus from Argentine and Chilean waterfowl migrating in the Pacific Flyway.

Estrategias de control de la Equinococosis quística en el Uruguay / Strategies for the control of cystic echinococcosis in Uruguay / Estratégias de controle da equinococose cística no Uruguai

La equinococosis quística es una zoonosis de origen parasitario con distribución cosmopolita. En nuestro país continúa siendo una enfermedad endémica, afectando principalmente pequeños centros poblados y áreas rurales pobres relacionadas a la producción ovina. Los planes de control requieren de un abordaje holístico, con la participación de diferentes instituciones, profesionales y en especial de la comunidad. La cooperación regional busca monitorizar el avance de la enfermedad y centrar las medidas de acción sobre cuatro ejes, definidos según los puntos de intervención más comunes para la quiebra del ciclo de transmisión y la consecuente reducción en incidencia y prevalencia de la enfermedad. La presente revisión utilizó literatura obtenida en diferentes bases de datos, bibliotecas virtuales y sitios web regionales y locales con el objetivo describir las principales estrategias de control, vigilancia y prevención aplicadas actualmente en nuestro país.

Cystic echinococcosis is a zoonosis of parasitic origin with cosmopolitan distribution. In our country it continues to be an endemic disease, affecting mainly small population centers and poor rural areas related to sheep production. Control plans require a holistic approach, with the participation of different institutions, professionals and especially the community. Regional cooperation seeks to monitor the progress of the disease and focus action measures on four axes, defined according to the most common points of intervention to break the transmission cycle and consequently reduce the incidence and prevalence of the disease. This review used literature obtained from different databases, virtual libraries and regional and local websites with the aim of describing the main control, surveillance and prevention strategies currently applied in our country.

Epidemiology of dog bites to people in Uruguay (2010-2020).

BACKGROUND: Dog bites to people are a serious public health problem. Limited information exists at the country level in Latin America. The COVID-19 pandemic changed people's lifestyles and their relationship with pets, and this could potentially affect the incidence of dog bites injuries. OBJECTIVE: The main objectives of our study were to determine the prevalence of dog-bite injuries in Uruguay from 2010 to 2020 and to compare the prevalence in 2020 to that of pre-pandemic years. METHODS: Cross-sectional study. Dog-bite notifications for the 2010 and 2020 period were analysed using data from the Uruguayan Ministry of Public Health. RESULTS: The annual dog-bite injury rate for the 2010-2020 period was 87.51 per 100,000 people. The frequency of bites varied with the victims' sex, with males accounting for 51.8% of the bites (p < 0.0001), and with age, with a higher frequency of bites in the ≤14 years old age group (p < 0.01). The frequency of dog bites was also higher in spring and summer than in autumn (p < 0.0001). There was no statistical difference in the frequency of dog-bite injuries when comparing 2020 with the pre-COVID-19 pandemic years. CONCLUSIONS: In Uruguay, the frequency of dog-bite injuries varied with season and with the age and sex of the victim. In the first year of the COVID-19 pandemic, the number of people bitten by dogs was no different than that of previous years. This is the first study in Latin America to report national rather than regional data and to include all age groups.

[Legalization of Recreational Cannabis use in Germany - Implications Based on Experiences in Uruguay, Canada und USA: a Narrative Review]. / Cannabislegalisierung in Deutschland ­ Implikationen aufgrund der Erfahrungen aus Uruguay, Kanada und den USA: ein narratives Review.

The current government of Germany has agreed on legalizing the recreational use of cannabis in their coalition agreement. Legalization will be implemented in 2023. This issue has continuously been a subject of controversial discussion including most parts of society, executive authorities and science. This article refers to the experiences of other countries (Uruguay, Canada, USA) yet having legalized Cannabis in the past and tries to discuss implications for Germany.

Dietary Acid Load and Cancer Risk: A Review of the Uruguayan Experience.

Dietary acid load (DAL) is recognized as a risk factor for several chronic disorders, including obesity, diabetes, and osteoporosis. Recent evidence suggests that an elevated DAL, as measured by the validated potential renal acid load (PRAL) and net endogenous acid production (NEAP) scores, could also increase the risk for several cancers. This narrative review summarizes the potential role of DAL in Uruguayan cancer patients and outlines the potentially involved pathophysiological pathways that mediate the role of DAL in both cancer development and growth. Although Uruguay is a developing country, its average diet is a heavily meat-based Western one, translating into a supraphysiological acid burden from diet. In recent years, we have published epidemiologic evidence based on ten case-control studies involving 3736 cancer cases and 9534 hospital-based controls. Odds ratios and 95% confidence intervals were estimated for each interest variable to analyze the association between the exposure levels of DAL scores and cancer, calculated by unconditional logistic regression. In a majority of the cases, the highest DAL scores tended to double the cancer risk as compared to the lowest category. We also found high risks for methionine intake, an acidifying amino acid found in higher concentrations in animal-based foods, which may increase cancer risks at least by a joint action based on the pH and the proliferation enhancing properties of the amino acid itself.

Insights into the Y chromosome human diversity in Uruguay.

BACKGROUND: With regard to the origin of its population and microevolutionary processes, Uruguay exhibits distinctive features that distinguish it from other countries in Latin America, while at the same time sharing several similarities. In this article, we will focus on the variability of paternal genetic lineages in two geographical regions with different histories that can be considered as examples of distinct populations for the continent. In general terms, the genetic diversity is a result of different demographic processes related to the American conquest and colonisation. These resulted in distinct ancestral components which vary geographical and depend on the distribution by sex within these components. In Uruguay, native maternal haplogroups are significantly more frequent in the North. Although there are several studies about the geneticvariability of Uruguay, little is known about male genetic lineages. AIMS: The aim of this work is to present an updated study of the male genetic variability of the Uruguayan population. METHODS: We analyzed 13 biallelic markers and 27 STRs located in the male-specific region of the Y chromosome for 157 males: 98 from the capital, Montevideo, and 59 from Tacuarembó. RESULTS: Almost all haplogroups found in both locations are European (99% and 93.2% respectively). One Sub-Saharan African haplogroup was found in Montevideo (1%) and 2 in Tacuarembó (3%), while Native haplogroups were found only in Tacuarembó, evidencing a strong sex-biased admixture. By crossing genetic and genealogical information we could relate European haplogroups with different waves and times of migrations. DISCUSSION: Network analysis indicated a very diverse male population, suggesting that European migrants came from heterogeneous geographic locations and in different waves. Tacuarembó has closer population affinities with Iberian populations while Montevideo is more diverse. Male population expansion expansion, can be explained by the large number of migrants that arrived during the XIX century and the first half of the XX century. CONCLUSIONS: The Uruguayan male gene pool is the result of several migration waves with diverse origins, with strong sex-biased admixture that can be explained by the European migration, the violence against the indigenous males, and the segregation of the Africansadmixture that can be explained due to European migration, violence against Natives, and segregation against African males.admixture that can be explained due to European migration, violence against Natives, and segregation against African males.admixture that can be explained due to European migration, violence against Natives, and segregation against African males.admixture that can be explained due to European migration, violence against Natives, and segregation of hte Africans.

Study of Candidemia and its Antifungal Susceptibility Profile at the University Hospital of Montevideo, Uruguay.

Systemic candidiasis are high mortality infections caused by yeasts of the genus Candida, affecting patients with numerous risk factors. Nowadays, candidemia produced by "non-albicans" species has increased considerably. Timely diagnosis and subsequent treatment substantially improve patients' survival. Our objectives are to study the frequency, distribution, and antifungal susceptibility profiles of candidemia isolates in our hospital. We conducted a descriptive, cross-sectional study. Positive blood cultures were recorded from January 2018 to December 2021. Positive Candida genus blood cultures were selected, classified, and analyzed on their susceptibility profile for amphotericin B, fluconazole and caspofungin using AST-YS08® card for VITEK 2 Compact® to determine minimum inhibitory concentration (MIC) and CLSI M60 2020 2nd Edition to determine breakpoints. 3862 positive blood cultures were obtained, 113 (2.93%) presented growth of Candida spp., corresponding to 58 patients. 55.2% came from the Hospitalization Ward and Emergency Services and 44.8% from the Intensive Care Unit. The species were distributed as follows: Nakaseomyces glabratus (Candida glabrata) (32.74%), Candida albicans (27.43%), Candida parapsilosis (23.01%), Candida tropicalis (7.08%) and others (9.73%). Most species were found to be susceptible to most antifungals, except for C. parapsilosis, presenting 4 isolates with resistance to fluconazole and N. glabratus (C. glabrata), whose clinical susceptibility data remains insufficient to provide accurate breakpoints. The percentage of recorded positive blood cultures of Candida spp. was 2.93%, these results were consistent with those reported at a regional level. A predominance of "non-albicans" species was observed. It is essential to know the prevalence, epidemiology, and susceptibility profiles of candidemia in our country, as well as being updated on its subsequent changes, maintaining epidemiological surveillance. This allows professionals to map out early and effective therapeutic strategies, staying alert of possible multi-resistant strains.

Assessment of radiation hazard indices due to naturally occurring long-life radionuclides in the coastal area of Barra de Valizas, Uruguay.

The Uruguayan east coast has several mineral resources, which include black sand ores in the Barra de Valizas-Aguas Dulces area. Cancer in Uruguay shows non-homogeneous geographical distribution, with the highest standardized mortality ratio (SMR) in the northeast and east region, which includes the aforementioned area and the town of Barra de Valizas. The activity concentration of natural radionuclides (226Ra, 232Th and 40 K) in Barra de Valizas´soil was determined by gamma spectrometry in order to evaluate the radiological hazard for inhabitants and tourists. The outdoor annual effective dose (AEDE), excess lifetime cancer risk (ELCR), and annual gonadal dose equivalent (AGDE) were evaluated for inhabitants with a life expectancy of 77.7 years, a 0.2 and 0.5 occupancy factor, and using the conversion coefficients recommended by United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR). The annual effective dose was also evaluated for both summer and fortnight tourists. The radiological hazard indices for Barra de Valizas inhabitants are higher than the worldwide mean and recommended values. This may contribute to Rocha's higher SRM value, although a direct correlation cannot be assured with the epidemiological information currently available. Social, medical and anthropological studies will be carried out in future to provide data and verify this correlation.

Molecular typing and antifungal susceptibility of clinical isolates of Cryptococcus neoformans and Cryptococcus gattii species complexes from the National Invasive Fungal Surveillance Network of Uruguay.

Cryptococcus neoformans and C. gattii species complexes (phylum: Basidiomycota) are environmental yeasts and are the main cause of human cryptococcosis worldwide. The most recent molecular typing studies in Latin America have focused on the intertropical region. Thus, this study aimed to update the knowledge of human cryptococcosis in the South American temperate region. We obtained and analyzed 116 C. neoformans/C. gattii species complexes isolates from the Public Health Surveillance Laboratory between 2008-2013 and 2017-2021 (C. gattii species complex = 1 and C. neoformans species complex = 115). The average patient age was 45 years, with an overall male:female ratio of 3.1:1. The proportion of HIV-negative patients was significantly higher in the second study period. Restriction fragment length polymorphism typing of URA5 gene revealed that the C. neoformans species complex comprised 75.7% VNI, 2.6% VNII, 0.9% VNIII, 1.7% VNIV, 17.4% VNII/VNIV hybrids, and one C. neoformans isolate (0.9%) misidentified as VGI; the C. gattii species complex isolates comprised one VGII. The overall case fatality rate was 49.5%, with no differences in lethality between VNI and hybrid isolates. Of the four isolates responsible for episodes of reoccurrence, only one had a genotype different from the first episode. Antifungal susceptibility testing revealed that most isolates fell below the local epidemiological cut-off value. This study provides additional information for the analysis of C. neoformans/C. gattii species complexes dynamics in the South American temperate region.

This study describes the epidemiological and molecular trends of human cryptococcosis according to the public health Uruguayan surveillance network. The findings provide additional information for analyzing the Cryptococcusneoformans/C. gattii species complexes in the South American temperate region.

End-of-season influenza vaccine effectiveness during the Southern Hemisphere 2022 influenza season - Chile, Paraguay, and Uruguay.

OBJECTIVES: This study estimated the 2022 end-of-season influenza vaccine effectiveness (VE) against severe acute respiratory illness (SARI) hospitalization in Chile, Paraguay, and Uruguay. METHODS: We pooled surveillance data from SARI cases in 18 sentinel surveillance hospitals in Chile (n = 9), Paraguay (n = 2), and Uruguay (n = 7) from March 16-November 30, 2022. VE was estimated using a test-negative design and logistic regression models adjusted for country, age, sex, presence of ≥1 comorbidity, and week of illness onset. VE estimates were stratified by influenza virus type and subtype (when available) and influenza vaccine target population, categorized as children, individuals with comorbidities, and older adults, defined per countries' national immunization policies. RESULTS: Among the 3147 SARI cases, there were 382 (12.1%) influenza test-positive case patients; 328 (85.9%) influenza case patients were in Chile, 33 (8.6%) were in Paraguay, and 21 (5.5%) were in Uruguay. In all countries, the predominant subtype was influenza A(H3N2) (92.6% of influenza cases). Adjusted VE against any influenza-associated SARI hospitalization was 33.8% (95% confidence interval: 15.3%, 48.2%); VE against influenza A(H3N2)-associated SARI hospitalization was 30.4% (95% confidence interval: 10.1%, 46.0%). VE estimates were similar across target populations. CONCLUSION: During the 2022 influenza season, influenza vaccination reduced the odds of hospitalization among those vaccinated by one-third. Health officials should encourage influenza vaccination in accordance with national recommendations.

Prevalencia de Síndrome de Burnout en trabajadores de la salud en el primer nivel de atención / Prevalence of Burnout Syndrome in health care workers at the first level of care / Prevalência da Síndrome de Burnout em trabalhadores do setor de saúde no primeiro nível de atendimento

Introduction: Burnout syndrome, also known as professional burnout syndrome, when it manifests itself has the capacity to affect the quality of life, mental health and even put the life of the person who presents it at risk. The aim of this research was to explore the prevalence and factors associated with Burnout Syndrome in health care workers at the first level of care. Material and methods: a cross-sectional observational study was carried out. A total of 213 health workers who worked at the first level of care centers of the Military Health Service participated in the study. The data collection instrument was sent by WhatsApp, self-administered, a part oriented to sociodemographic aspects and the Maslach Burnout Inventory focused on the three dimensions of Burnout. The data were analyzed in Excel and Epi-info7.0. Results: when evaluating the Maslach Scale factors, it was observed that 38% presented High Emotional Fatigue, 22% Low Personal Accomplishment and 18% High Depersonalization. Thirteen participants presented the three risk dimensions, which corresponds to a prevalence of Burnout Syndrome of 6% in this population. Conclusions: It was necessary to install a dialogue in relation to the impact generated and its degree of affectation in the subjects. It is necessary to reflect on tools that promote positive aspects of occupational health and adequate occupational hygiene. Likewise, it is necessary to strengthen preventive programs, thus providing workers with a follow-up in order to improve occupational health.
