Risk factors associated with severe COVID-19 outcomes in Jamaica: a cross-sectional study of national surveillance data.

Objectives: To describe the characteristics and outcomes of COVID-19 cases in Jamaica and to explore the risk factors associated with severe COVID-19 from 9 March to 31 December 2020. Methods: A cross-sectional analysis of national surveillance data was conducted using confirmed COVID-19 cases in Jamaica. Definitions of a confirmed case, disease severity, and death were based on World Health Organization guidelines. Chi-square and Fisher exact tests were used to determine association with outcomes. Logistic regression models were used to determine predictors of severe COVID-19. Results: This analysis included 12 169 cases of COVID-19 (median age, 36 years; 6 744 females [ 55.4%]) of which 512 cases (4.2%) presented with severe disease, and of those, 318 patients (62.1%) died (median age at death, 71.5 years). Severe disease was associated with being male (OR 1.4; 95% CI, 1.2-1.7) and 40 years or older (OR, 6.5; 95% CI, 5.1-8.2). COVID-19 death was also associated with being male (OR, 1.4; 95% CI, 1.1-1.7), age 40 years or older (OR, 17.9; 95% CI, 11.6-27.7), and in the Western versus South East Health Region (OR 1.7; 95% CI, 1.2-2.3). Conclusions: The findings of this cross-sectional analysis indicate that confirmed cases of COVID-19 in Jamaica were more likely to be female and younger individuals, whereas COVID-19 deaths occurred more frequently in males and older individuals. There is increased risk of poor COVID-19 outcomes beginning at age 40, with males disproportionately affected. COVID-19 death also varied by geographic region. This evidence could be useful to other countries with similar settings and to policymakers charged with managing outbreaks and health.

Continued decline in the incidence of myocardial infarction beyond the COVID-19 pandemic: a nationwide study of the Swedish population aged 60 and older during 2015-2022.

The number of myocardial infarctions declined during the early COVID-19 pandemic but mechanisms behind these declines are poorly understood. COVID-19 infection is also associated with an increased risk of myocardial infarction which could lead to higher incidence rates in the population. This study aims to shed light on the seemingly paradoxical relationship between COVID-19 and myocardial infarction occurrence on the population level by exploring long-term trends in incidence rates, case fatality, and proportion of patients dying before reaching a hospital. Our work is based on a linkage of administrative registers covering the entire population aged 60 + in Sweden. Considering both long-term trends since 2015 and seasonal variability, we compared observed incidence, case fatality, and proportions of patients hospitalized to expected values during 2020-2022. Despite more than 200 laboratory-confirmed COVID-19 cases per 1000 inhabitants by the end of 2022, incidence rates of myocardial infarction continued to decline, thus following the long-term trend observed already before 2020. During the first pandemic wave there was an additional incidence decline corresponding to 13% fewer myocardial infarctions than expected. This decline was neither accompanied by increasing case fatality nor by lower shares of patients being hospitalized. We found no increase in the population-level incidence of myocardial infarction despite large-scale exposure to COVID-19, which suggests that the effect of COVID-19 on myocardial infarction risk is not substantial. Increased pressure on the Swedish health care system has not led to increased risks or poorer outcomes for patients presenting with acute myocardial infarction.

Wastewater surveillance for COVID-19 in shelters: A creative strategy for a complex setting.

People experiencing homelessness experience disproportionate rates of morbidity and mortality from coronavirus disease 2019 (COVID-19) compared to the general population and shelters for people experiencing homelessness are a major contributing factor to these negative outcomes. As a result of their unique structure, population and physical space, these settings pose several challenges to the prevention of COVID-19 infection that are not adequately addressed by conventional non-pharmaceutical public health interventions. Wastewater surveillance for COVID-19 is a viable strategy for health protection in shelters due to its ability to meet these unique challenges. Its passive nature does not depend on individual health-seeking behaviours, and it can provide useful epidemiological information early on in an outbreak setting. In this commentary, the authors examine a recent application of wastewater surveillance of COVID-19 in a men's shelter in Toronto. Further applications of wastewater surveillance for other infectious diseases of concern in shelters are proposed, and the need for the development of ethical frameworks governing the use of this technology is discussed.

Local Antimicrobial Resistance Trends in Pediatric Urinary Tract Infection: The Importance of Local Surveillance of a Global Problem.

Introduction Urinary tract infections (UTIs) are one of the most common pediatric bacterial infections and consequently a major reason for antibiotic treatment. Despite being a global problem, antimicrobial resistance is often geographically heterogeneous. Thus, it is fundamental to know local epidemiology and practice frequent surveillance of each hospital's antibiograms. The aims of this study are to determine the local antimicrobial resistance profile in pediatric UTIs, to understand its evolution over 14 years, and finally, to infer if the currently instituted antibiotic empirical therapy remains effective. Materials and methods A retrospective observational study was performed through the analysis of urine cultures and respective antibiograms of children diagnosed with UTI from 2017 to 2019 in Centro Hospitalar Universitário do Algarve (Faro's unit, Portugal), followed by a comparison of the obtained data with the results of a similar study performed between 2003 and 2005. Results A total of 784 urine cultures were selected. Escherichia coli was the most frequent microorganism (n = 561; 71.56%), followed by Proteus mirabilis (n = 117; 14.92%) and Klebsiella pneumoniae (n = 40; 5.10%). The most commonly prescribed antibiotic was cefuroxime axetil (66.28%). Escherichia coli had an increase in resistance to amoxicillin-clavulanate of 6.16% to 34.76% and cefuroxime axetil of 0.73% to 4.46%. Proteus mirabilis had an increase in resistance to amoxicillin-clavulanate of 1.64% to 11.11%. Klebsiella pneumoniae had an increase in resistance to cefuroxime axetil (0%-27.50%) and nitrofurantoin (0%-47.50%). The three microorganisms showed a decrease in trimethoprim-sulfamethoxazole resistance profiles, as well as low resistance profiles to fosfomycin. In fifty cases in which antibiotic empirical therapy was instituted, the isolated microorganism revealed in vitro resistance; 37 of these cases had a good evolution, maintaining the antibiotic empirical therapy. Discussion Local surveillance of antimicrobial resistance allows monitoring of the resistance trends and adequacy of empirical antibiotic therapy. This study's local resistance profile was distinct from other regions of the country and the world. Continuous local surveillance also potentiates the dissemination of the results to the concerned healthcare providers and the initiation of timely responsive measures, containing the increase in antimicrobial resistance. As Escherichia coli was the commonest isolated microorganism, its antimicrobial profile should dictate antibiotic empirical therapy. This study supports that in vitro is not equivalent to in vivo resistance. Conclusion There was a significant increase in antimicrobial resistance profiles, especially to amoxicillin-clavulanate. Cefuroxime axetil remains the recommended antibiotic for empirical therapy in this hospital, although fosfomycin should be considered as an alternative in non-complicated cystitis in adolescent females. This study reinforces the importance of continuous local resistance surveillance as a preventive measure against the global increase in antimicrobial resistance.

Results from the SARS-CoV-2 wastewater-based surveillance system in Denmark, July 2021 to June 2022.

The microbiological analysis of wastewater samples is increasingly used for the surveillance of SARS-CoV-2 globally. We described the setup process of the national SARS-CoV-2 wastewater-based surveillance system in Denmark, presented its main results during the first year of activities, from July 2021 to June 2022, and discussed their operational significance. The Danish SARS-CoV-2 wastewater-based surveillance system was designed to cover 85 % of the population in Denmark and it entailed taking three weekly samples from 230 sites. Samples were RT-qPCR tested for SARS-CoV-2 RNA, targeting the genetic markers N1, N2 and RdRp, and for two faecal indicators, Pepper Mild Mottle Virus and crAssphage. We calculated the weekly SARS-CoV-2 RNA concentration in the wastewater from each sampling site and monitored it in view of the results from individual testing, at the national and regional levels. We attempted to use wastewater results to identify potential local outbreaks, and we sequenced positive wastewater samples using Nanopore sequencing to monitor the circulation of viral variants in Denmark. The system reached its full implementation by October 2021 and covered up to 86.4 % of the Danish population. The system allowed for monitoring of the national and regional trends of SARS-CoV-2 infections in Denmark. However, the system contribution to the identification of potential local outbreaks was limited by the extensive information available from clinical testing. The sequencing of wastewater samples identified relevant variants of concern, in line with results from sequencing of human samples. Amidst the COVID-19 pandemic, Denmark implemented a nationwide SARS-CoV-2 wastewater-based surveillance system that integrated routine surveillance from individual testing. Today, while testing for COVID-19 at the community level has been discontinued, the system is on the frontline to monitor the occurrence and spread of SARS-CoV-2 in Denmark.

Building-level wastewater surveillance localizes interseasonal influenza variation.

Influenza virus poses a recurring threat to public health and infects many populations in annual waves of generally unpredictable magnitude and timing. We aimed to detect the arrival and estimate the case magnitude of seasonal influenza A in urban New York City college dormitory buildings. Our wastewater-based surveillance (WBS) program measured viral RNA in the sewage outflow of three dormitories at Barnard College in 2021 and 2022. Wastewater test positivity strongly correlated with New York County clinical cases (Kendall's τ = 0.58). Positive wastewater samples are also associated with campus clinical cases. The 2022 data stand in stark contrast to the 2021 results by revealing the more frequent and earlier presence of influenza A. The increase in positive tests is significant (P < 0.01). It is further noteworthy that positive samples were not evenly distributed among buildings. Surveillance additionally identified the influenza A H3 subtype but did not detect any influenza B. We also systematically analyzed our viral purification protocol to identify in which fraction influenza can be found. While virus can be found in solid fractions, a substantial quantity remains in the final liquid fraction. Our work focuses on individual buildings rather than larger sewersheds because buildings may localize interseasonal influenza variation to specific subpopulations. Our results highlight the potential value of building-level WBS in measuring influenza incidence to help guide public health intervention.IMPORTANCESeasonal influenza remains a major public health burden. We monitored influenza A in dormitory wastewater of a New York City college in 2021 and 2022. Longitudinal samples acquired over consecutive years allowed measurement of individual buildings between seasons. We uncovered building-level changes in the magnitude and timing of test positivity concordant with clinical cases. Surveillance also localized the heterogeneity of influenza variation during the large 2022 seasonal surge. The ability to detect such changes could be leveraged as part of a public health response.

Open data for monitoring COVID-19 in Spain: Descriptive study.

BACKGROUND: The indicators of the pandemic have been based on the total number of diagnosed cases of COVID-19, the number of people hospitalized or in intensive care units, and deaths from the infection. The aim of this study is to describe the available data on diagnostic tests, health service used for the diagnosis of COVID-19, case detection and monitoring. METHOD: Descriptive study with review of official data available on the websites of the Spanish health councils corresponding to 17 Autonomous Communities, 2 Autonomous cities and the Ministry of Health. The variables collected refer to contact tracing, technics for diagnosis, use of health services and follow-up. RESULTS: All regions of Spain show data on diagnosed cases of COVID-19 and deaths. Hospitalized cases and intensive care admissions are shown in all regions except the Balearic Islands. Diagnostic tests for COVID-19 have been registered in all regions except Madrid region and Extremadura, with scarcely information on what type of test has been performed (present in 7 CCAA), requesting service and study of contacts. CONCLUSIONS: The information available on the official websites of the Health Departments of the different regions of Spain are heterogeneous. Data from the use of health service or workload in Primary Care, Emergency department or Out of hours services are almost non-existent.

The effect of changing diagnostic method from culture to PCR on the number of episodes of human campylobacteriosis in Denmark: a retrospective study (2015-2022).

IMPORTANCE: This study is important because it shows the potential epidemiological silence associated with the use of culture as the primary diagnostic method for the laboratory identification of human campylobacteriosis. Also, we show how polymerase chain reaction methods are associated with a systematic increase in the number of human campylobacteriosis episodes as reported by routine disease surveillance. These findings are operationally relevant and have public health implications because they tell how crucial it is to consider changes in diagnostic methods, e.g., in the epidemiological analysis of historical data and in the interpretation of future data in light of the past. We also believe that this study highlights how the synergy between microbiology and epidemiology is essential for disease surveillance.

Maternal health surveillance panel: a tool for expanding epidemiological surveillance of women's health and its determinants / Painel de vigilância da saúde materna: uma ferramenta para ampliação da vigilância epidemiológica da saúde das mulheres e seus determinantes

ABSTRACT Objective: To present the methodology used in the development of two products for maternal health surveillance and its determinants and discuss their possible uses. Methods: Based on a theoretical model of the determinants of maternal death and databases of Brazilian health information systems, two free products were developed: an interactive panel "surveillance of maternal health" and an educational material "Aparecida: a story about the vulnerability of Brazilian women to maternal death", both available on the website of the Brazilian Obstetric Observatory. Results: More than 30 indicators were calculated for the period 2012-2020, containing information on socioeconomic conditions and access to health services, reproductive planning, prenatal care, delivery care, conditions of birth and maternal mortality and morbidity. The indicators related to severe maternal morbidity in public hospitalizations stand out, calculated for the first time for the country. The panel allows analysis by municipality or aggregated by health region, state, macro-region and country; historical series analysis; and comparisons across locations and with benchmarks. Information quality data are presented and discussed in an integrated manner with the indicators. In the educational material, visualizations with national and international data are presented, aiming to help in the understanding of the determinants of maternal death and facilitate the interpretation of the indicators. Conclusion: It is expected that the two products have the potential to expand epidemiological surveillance of maternal health and its determinants, contributing to the formulation of health policies and actions that promote women's health and reduce maternal mortality.

RESUME Objetivo: Apresentar a metodologia utilizada no desenvolvimento de dois produtos para a vigilância da saúde materna e seus determinantes e discutir as suas possíveis utilizações.

Conclusão: Espera-se que os produtos tenham o potencial de ampliar a vigilância epidemiológica da saúde materna e seus determinantes, contribuindo para a formulação de políticas e ações de saúde que promovam a saúde das mulheres e reduzam a mortalidade materna.

Surveillance system for Healthcare-associated endophthalmitis at state level in a middle-income country: preliminary results / Sistema de vigilância epidemiológica para endoftalmites em nível estadual em um país de renda média: resultados preliminares

ABSTRACT Purpose: To describe the implementation pro cess and the preliminary results of a surveillance system for healthcare-associated endophthalmitis. Methods: This is a case study of the implementation of a surveillance system for healthcare-associated endophthalmitis. The system for healthcare-associated endophthalmitis is a structured system that enables surveillance of cases of healthcare-associated endophthalmitis after intraocular procedures, developed and coordinated by the Division of Hospital Infection at the State Health Department, São Paulo, Brazil. The implementation process included a pilot phase, followed by a scaling-up phase. Data were reported monthly to the Division of Hospital Infection by participating healthcare facilities that performed intraocular procedures in the state of São Paulo, Brazil, from September 2017 to December 2019. Results: Among the 1,483 eligible healthcare facilities, 175 engaged in the study (participation rate of 11.8%), reporting 222,728 intraocular procedures performed, of which 164,207 were cataract surgery and 58,521 were intravitreal injections. The overall incidence rate of endophthalmitis was reported to be 0.05% (n=105; 80 cases after cataract surgery and 25 cases after intravitreal injections). The incidence rates for healthcare facilities ranged from 0.02% to 4.55%. Most cases were caused by gram-positive bacteria, mainly Staphylococcus spp. In 36 (46.2%) of the cases, there was no bacterial growth; no sample was collected in 28 (26.7%) cases. This system for healthcare-associated endophthalmitis enabled the identification of an outbreak of four cases of endophthalmitis after intravitreal injections. Conclusion: The system for healthcare-associated endophthalmitis proved to be operationally viable and efficient for monitoring cases of endophthalmitis at the state level.

Temporal trends in vaccination coverage in the first year of life in Brazil / Tendência temporal das coberturas vacinais no primeiro ano de vida no Brasil

ABSTRACT Objective: The aim of this study was to analyze the temporal trends in vaccination coverage (VC) during the first year of life of children in Brazil. Methods: Data on VC for the first year of life from 2011 to 2020 for Bacille Calmette-Guerin (BCG), hepatitis B, polio, pentavalent, and triple viral vaccines at the national, regional, and state levels were obtained from the Information System of the National Immunization Program. Trends were analyzed using Prais-Winsten generalized linear regression models and average annual percent change (APC) estimates. Results: Decreasing trends were observed for the BCG (APC −3.58%; p<0.05), pentavalent (APC −4.10%; p<0.05), polio (APC −2.76%; p<0.05), and triple viral (APC −2.56%; p<0.05) vaccines in the country. Hepatitis B vaccine was the only vaccine that displayed stationary behavior (APC −4.22%; p>0.05). During the study period, no increasing trends were observed in any territory or vaccine. Conclusions: This study shows a recent significant reduction and decreasing trends in VC during the first year of life of children in Brazil, indicating the need for interventions to curb this ongoing phenomenon and to recover acceptable VC rates in the country.

Recognize the epidemiological and geospatial profile of the Mobile Emergency Care Service: a strategy to optimize response time

Epidemiological, cross-sectional, descriptive, retrospective study of a quantitative nature, to trace the epidemiological and geospatial profile of the occurrences assisted by the Mobile Emergency Care Service. For that purpose, secondary data from the documents of the Mobile Emergency Care Service of a city in the interior of Rio Grande do Norte were used, considering the frequency of the variables: sex, age group, nature of occurrences, days of the week, ambulance sent, removal inter-hospital care and patient destination. Of the 363 occurrences, most were due to clinical causes, followed by traumatic, psychiatric, and gynecological/obstetric causes, with an emphasis on cardiovascular diseases and transport accidents. aged 19 to 59 years and over 60 years, with the Basic Support Unit providing the majority of care. Among the calls for clinical causes, women stood out, while for traumatic and psychiatric causes, men. The information contributes to the organization and planning of the service and the understanding of the morbidity profile. The geographic distribution highlights the need for integration between health agencies, for the institution of preventive actions, and the redirection of human and financial resources.

Estudio epidemiológico, transversal, descriptivo, retrospectivo, de carácter cuantitativo que tiene como objetivo trazar el perfil epidemiológico y geoespacial de los incidentes atendidos por el Servicio Móvil de Atención de Urgencias.

De los 363 sucesos, la mayoría se debió a causas clínicas, seguidas de causas traumáticas, psiquiátricas y ginecológicas/obstétricas, incluidas las enfermedades cardiovasculares y los accidentes de transporte. La frecuencia de ocurrencia fue ligeramente mayor en individuos masculinos con predominio de mujeres y edades entre los 19 y 59 años y mayores de 60 años; la Unidad Básica de Apoyo fue la responsable de la mayoría de los servicios. Entre los lesionados por causas clínicas destacan las mujeres, mientras que los hombres tienen causas traumáticas y psiquiátricas. Esta información contribuye a la organización y planificación de los servicios y a la comprensión del perfil de morbilidad. La distribución geográfica resalta la necesidad de integración entre las organizaciones de salud para implementar acciones preventivas y redireccionar recursos humanos y financieros.

SARS-CoV-2 rapid antigen testing positive rate in community testing stations as an indicator for COVID-19 epidemic trend, Taipei, Taiwan, May to August 2021.

BACKGROUND: Real-time surveillance of COVID-19 in large-scale community outbreaks presents challenges. Simple counts of the daily confirmed cases can be misleading due to constraints from bottlenecks in access to care or laboratory testing. This study aimed to investigate the role of the SARS-CoV-2 antigen rapid diagnostic test (Ag-RDT) in addressing these challenges for real-time COVID-19 surveillance. METHODS: This study included the results of 86,994 SARS-CoV-2 Ag-RDT and real-time reverse transcription polymerase chain reaction (RT-PCR) tests. These were conducted at four community testing stations within the Taipei metropolitan area during a community COVID-19 outbreak spanning from May 17, 2021, to August 9, 2021. We examined the correlation between the positive rates of Ag-RDT tests and the epidemic curve of laboratory-confirmed COVID-19 cases by onset date to examine its role in real-time surveillance. RESULTS: During the 85-day study period, the trend of Ag-RDT test positive rates paralleled that of the epidemic curve. The correlation between the Ag-RDT positive rate and the number of cases (Pearson correlation coefficient: 0.968) is comparable to that of the RT-PCR positive rate (Pearson correlation coefficient: 0.964). The Ag-RDT positive rate exhibited a more advanced leading trend, with Ag-RDT leading by 3 days in comparison to the 2-day lead for RT-PCR. CONCLUSION: The positive rate of SARS-CoV-2 Ag-RDT tests at community testing stations serves as a good surrogate for assessing virus activity within the community and a useful tool for real-time COVID-19 surveillance. It is a robust indicator of the outbreak trend and near-term numbers of cases. This finding may facilitate the management of subsequent outbreaks of emerging infectious diseases.

Nationwide Trends in Non-COVID-19 Infectious Disease Laboratory Tests in the Era of the COVID-19 Pandemic in Korea.

The coronavirus disease 2019 pandemic has brought significant changes to infectious disease management globally. This study explored changes in clinical microbiological testing trends and their implications for infectious disease incidence and medical utilization during the pandemic. We collected nationwide claims for monthly clinical microbiology tests from January 2018 to March 2022 using the National Health Insurance Service database. Seasonal autoregressive integrated moving average models were employed to make predictions for each disease based on the baseline period (January 2018 to January 2020). The results showed a significant decrease in general bacterial and fungal cultures, respiratory infectious disease-related, and inflammatory markers, while the representatives of tests for vector-borne diseases, healthcare-associated infections, and chronic viral infections remained stable. The study highlights the potential of clinical microbiological testing trends as an additional surveillance tool and offers implications for future infectious disease management and surveillance strategies in pandemic settings.

Applications of Artificial Intelligence in Microbial Diagnosis.

The diagnosis is an important factor in healthcare care, and it is essential to identify microorganisms that cause infections and diseases. The application of artificial intelligence (AI) systems can improve disease management, drug development, antibiotic resistance prediction, and epidemiological monitoring in the field of microbial diagnosis. AI systems can quickly and accurately detect infections, including new and drug-resistant strains, and enable early detection of antibiotic resistance and improved diagnostic techniques. The application of AI in bacterial diagnosis focuses on the speed, precision, and identification of pathogens and the ability to predict antibiotic resistance.

Actualización sobre la resistencia antimicrobiana en instituciones de salud de nivel III y IV en Colombia entre enero del 2018 y diciembre del 2021

Introducción. El comportamiento de la resistencia antimicrobiana es fundamental en el mejoramiento y ajuste de los programas de optimización de uso de antimicrobianos, la implementación de las guías terapéuticas y las precauciones que limitan la transmisión cruzada de bacterias resistentes entre pacientes. Desde el inicio del 2020, la pandemia del SARS-CoV-2 desafió profundamente al sistema de salud y, según algunos reportes, aumentó las tasas de resistencia antimicrobiana. Objetivo. Describir el comportamiento de la resistencia antimicrobiana en los microrganismos más frecuentes en veinte hospitales colombianos durante el periodo 2018-2021. Materiales y métodos. Se trata de un estudio descriptivo basado en la información microbiológica reportada por veinte instituciones de salud de nivel III y IV, entre enero de 2018 y diciembre de 2021, en doce ciudades de Colombia, las cuales hacen parte del "Grupo para el estudio de la resistencia nosocomial en Colombia", liderado por la Universidad El Bosque. La identificación de género y especie de los microorganismos más frecuentes, junto con su perfil de resistencia frente a antibióticos marcadores, se determinaron mediante el análisis de los datos vía WHONET. Resultados. En general, los 10 microorganismos más frecuentes analizados a lo largo de los 4 años no presentaron cambios estadísticamente significativos en sus perfiles de resistencia durante los cuatro años del periodo evaluado, de 2018 a 2021. En contraste, Pseudomonas aeruginosa aumentó su resistencia frente a piperacilinatazobactam y carbapenémicos, lo cual fue estadísticamente significativo. Conclusiones. Los cambios en la resistencia antimicrobiana en estos años no han sido estadísticamente significativos, excepto para P. aeruginosa, bacteria que mostró un incremento en las tasas de resistencia a piperacilina-tazobactam y carbapenémicos.

Introduction. Antimicrobial resistance surveillance is a fundamental tool for the development, improvement, and adjustment of antimicrobial stewardship programs, therapeutic guidelines, and universal precautions to limit the cross-transmission of resistant bacteria between patients. Since the beginning of 2020, the SARS-CoV-2 pandemic profoundly challenged the health system and, according to some reports, increased the rates of antimicrobial resistance. Objective. To describe the behavior of antimicrobial resistance of the most frequent bacterial pathogens in twenty Colombian hospitals from January 2018 to December 2021. Materials and methods. We conducted a descriptive study based on the microbiological information recorded from January 2018 to December 2021 in twenty levels III and IV health institutions in twelve Colombian cities. We identified the species of the ten most frequent bacteria along with their resistance profile to the antibiotic markers after analyzing the data through WHONET. Results. We found no statistically significant changes in most pathogens' resistance profiles from January 2018 to December 2021. Only Pseudomonas aeruginosa had a statistically significant increase in its resistance profile, particularly to piperacillin/ tazobactam and carbapenems. Conclusions. The changes in antimicrobial resistance in these four years were not statistically significant except for P. aeruginosa to piperacillin/tazobactam and carbapenems.

Congenital syphilis in Roraima and Venezuelan migration: analysis of cases at the state maternity hospital in the 2017/2018 and 2020/2021 biennia / Sífilis congênita em Roraima e a migração venezuelana: análise de casos na maternidade estadual nos biênios 2017/2018 e 2020/2021 / Sífilis congénita en Roraima y migración venezolana: análisis de casos en la maternidad estatal en los bienios 2017/2018 y 2020/2021

Background and objectives: in 2017 and 2018, Roraima experienced the most significant increase in congenital syphilis incidence rates among all federal units. This phenomenon occurred in parallel with the significant Venezuelan migration to the region. The study aimed to analyze the relationship between the increase in cases of congenital syphilis registered at the Hospital Materno Infantil Nossa Senhora de Nazareth and the Venezuelan migratory crisis. Methods: this is a document-based, descriptive research, covering the 2017/2018 and 2020/2021 periods, developed from data collected in copies of congenital syphilis report/investigation forms from the hospital. Results: in the 2017/2018 biennium, the peak of Venezuelan migration in Roraima, fewer cases of syphilis occurred than when the migratory flow declined. In the 2020/2021 biennium, there was a decrease in the migratory flow due to the closing of the border and the acceleration of the interiorization process. Although it is the period with the highest number of reports of congenital syphilis among Venezuelan mothers, the percentage is considerably lower than that recorded among Brazilian women. The incidence rate was higher among the group of Brazilian mothers (7.5/1,000 live births, in the 2017/2018 period, and 11.5/1,000 live births, in the 2020/2021 period). Conclusion: Venezuelan migration, although it may have eventually exerted some influence on the total number of cases of congenital syphilis, cannot be considered the determining factor for the increase in cases of the disease in the hospital in the defined period, and other factors deserve to be assessed as decisive in this case.(AU)

Justificativa e objetivos: em 2017 e 2018, Roraima apresentou o aumento mais significativo nas taxas de incidência de sífilis congênita entre todas as unidades federativas. Este fenômeno ocorreu paralelamente à significativa migração venezuelana para a região. O estudo teve como objetivo analisar a relação entre o aumento de casos de sífilis congênita registrados no Hospital Materno Infantil Nossa Senhora de Nazareth e a crise migratória venezuelana. Métodos: trata-se de uma pesquisa documental, descritiva, abrangendo os períodos 2017/2018 e 2020/2021, desenvolvida a partir de dados coletados em cópias de fichas de notificação/investigação de sífilis congênita do hospital. Resultados: no biênio 2017/2018, pico da migração venezuelana em Roraima, ocorreram menos casos de sífilis do que quando o fluxo migratório diminuiu. No biénio 2020/2021, registou-se uma diminuição do fluxo migratório devido ao encerramento da fronteira e à aceleração do processo de interiorização. Embora seja o período com maior número de notificações de sífilis congênita entre mães venezuelanas, o percentual é consideravelmente inferior ao registrado entre as brasileiras. A taxa de incidência foi maior entre o grupo de mães brasileiras (7,5/1.000 nascidos vivos, no período 2017/2018, e 11,5/1.000 nascidos vivos, no período 2020/2021). Conclusão: A migração venezuelana, embora possa eventualmente ter exercido alguma influência no total de casos de sífilis congênita, não pode ser considerada o fator determinante para o aumento de casos da doença no hospital no período definido, e outros fatores merecem ser destacados. ser considerada decisiva neste caso.(AU)

Antecedentes y objetivos: en 2017 y 2018, Roraima experimentó el aumento más significativo en las tasas de incidencia de sífilis congénita entre todas las unidades federales. Este fenómeno se produjo en paralelo con la importante migración venezolana a la región. El estudio tuvo como objetivo analizar la relación entre el aumento de casos de sífilis congénita registrados en el Hospital Materno Infantil Nossa Senhora de Nazareth y la crisis migratoria venezolana. Métodos: se trata de una investigación descriptiva, documental, que abarca los períodos 2017/2018 y 2020/2021, desarrollada a partir de datos recolectados en copias de formularios de informe/investigación de sífilis congénita del hospital. Resultados: en el bienio 2017/2018, pico de migración venezolana en Roraima, ocurrieron menos casos de sífilis que cuando el flujo migratorio disminuyó. En el bienio 2020/2021 se produjo una disminución del flujo migratorio debido al cierre de fronteras y la aceleración del proceso de interiorización. Si bien es el período con mayor número de reportes de sífilis congénita entre madres venezolanas, el porcentaje es considerablemente menor que el registrado entre las mujeres brasileñas. La tasa de incidencia fue mayor entre el grupo de madres brasileñas (7,5/1.000 nacidos vivos, en el período 2017/2018, y 11,5/1.000 nacidos vivos, en el período 2020/2021). Conclusión: La migración venezolana, si bien eventualmente pudo haber ejercido alguna influencia en el número total de casos de sífilis congénita, no puede considerarse el factor determinante del aumento de casos de la enfermedad en el hospital en el período definido, y otros factores merecen ser considerados. considerarse decisivo en este caso.(AU)

Avances en políticas públicas y vigilancia epidemiológica relacionadas con el virus de inmunodeficiencia humana/sida en Ecuador

El virus de inmunodeficiencia humana constituye uno de los principales problemas de salud a nivel mundial. Se reconoce como un fenómeno multifactorial, donde las políticas públicas en materia de prevención, diagnóstico oportuno y tratamiento resultan claves. El objetivo del presente estudio es describir los avances en políticas públicas y vigilancia epidemiológica relacionadas con el virus de inmunodeficiencia humana/sida en Ecuador. Se evidencian importantes pasos con respecto al compromiso político y responsabilidad social para conseguir frenar los estragos del virus de inmunodeficiencia humana/sida, e infecciones de transmisión sexual, a partir de estrategias centradas en la prevención, así como en el tratamiento profiláctico, antirretroviral, y el seguimiento de los pacientes. Con vistas a ello se han implementado proyectos destinados a cumplir lo acordado en la declaración de las Naciones Unidas, y en el marco del plan nacional para el desarrollo. Persisten dificultades relacionadas con el acceso al diagnóstico del virus y pruebas de seguimiento, principalmente por la concentración de estas en una única institución.

The human immunodeficiency virus is one of the main health problems worldwide. It is recognized as a multifactorial phenomenon, where public policies regarding prevention, timely diagnosis and treatment are key. The objective of this study is to describe the advances in public policies and epidemiological surveillance related to the human immunodeficiency virus/AIDS in Ecuador. Important steps are evident in relation to political commitment and social responsibility to stop the injuries of the human immunodeficiency virus/AIDS, and sexually transmitted infections, based on strategies focused on prevention, as well as prophylactic, antiretroviral, and treatment patient follow-up. Some projects have been implemented aimed at fulfilling what was agreed in the United Nations declaration, and within the framework of the national development plan. Difficulties persist related to access to virus diagnosis and follow-up tests, mainly due to the concentration of these in a single institution.

Introducción: El comportamiento de la resistencia antimicrobiana es fundamental en el mejoramiento y ajuste de los programas de optimización de uso de antimicrobianos, la implementación de las guías terapéuticas y las precauciones que limitan la transmisión cruzada de bacterias resistentes entre pacientes. Desde el inicio del 2020, la pandemia del SARS-CoV-2 desafió profundamente al sistema de salud y, según algunos reportes, aumentó las tasas de resistencia antimicrobiana. OBJETIVO: Describir el comportamiento de la resistencia antimicrobiana en los microrganismos más frecuentes en veinte hospitales colombianos durante el periodo 2018-2021. Materiales y métodos: Se trata de un estudio descriptivo basado en la información microbiológica reportada por veinte instituciones de salud de nivel III y IV, entre enero de 2018 y diciembre de 2021, en doce ciudades de Colombia, las cuales hacen parte del "Grupo para el estudio de la resistencia nosocomial en Colombia", liderado por la Universidad El Bosque. La identificación de género y especie de los microorganismos más frecuentes, junto con su perfil de resistencia frente a antibióticos marcadores, se determinaron mediante el análisis de los datos vía WHONET. RESULTADOS: En general, los 10 microorganismos más frecuentes analizados a lo largo de los 4 años no presentaron cambios estadísticamente significativos en sus perfiles de resistencia durante los cuatro años del periodo evaluado, de 2018 a 2021. En contraste, Pseudomonas aeruginosa aumentó su resistencia frente a piperacilina-tazobactam y carbapenémicos, lo cual fue estadísticamente significativo. CONCLUSIONES: Los cambios en la resistencia antimicrobiana en estos años no han sido estadísticamente significativos, excepto para P. aeruginosa, bacteria que mostró un incremento en las tasas de resistencia a piperacilina-tazobactam y carbapenémicos.
