RESUMO
BACKGROUND: Topical treatments and botulinum toxin injections are valid options for the management of patients with chronic anal fissures (CAF), but little is known about the efficacy of these techniques in long-term follow-up. The aim of this meta-analysis was to evaluate the effectiveness, given to clinical outcomes, of medical treatments with calcium antagonists, nitroglycerin, and botulinum toxin on CAF treatment in adults. METHOD: A systemic review and meta-analysis developed according to PRISMA [PLoS Med. 2009 Jul 21;6(7):e1000100; BMJ. 2010 Mar 23;340:c332] and registered in PROSPERO (Registration number: CRD42020120386). A systematic literature search was conducted through MEDLINE, EMBASE, Web of Science, and Cochrane Library databases. Randomized control trials that compared medical treatment were identified; publications had to have a clinical definition of CAF with at least one of the following signs or symptoms: visible sphincter fibers at the base of the fissure, anal papillae, sentinel piles, and indurated margins. The symptoms had to be chronic for at least 4 weeks. Data were independently extracted for each study, and a meta-analysis was drawn using fixed- and random-effects models. RESULTS: 17 randomized trials met the inclusion criteria. Diltiazem showed a superior effect compared with glycerin (RR = 1.16 [95% CI = 1.05-1.30]; I2 = 18%) and with fewer adverse effects (RR = 0.13 [95% CI = 0.04-0.042]; I2 = 87%). Similar results were evidenced with the use of nifedipine compared with lidocaine (RR = 4.53 [95% CI = 2.99-6.86]; I2 = 28%). Botulinum toxin did not show statistically significant differences compared to glycerin (RR = 0.81 [95% CI = 0.02-29.36]; I2 = 93%) or isosorbide dinitrate (RR = 1.45 [95% CI = 0.32-6.54]; I2 = 85%). Regarding recurrence, nifedipine was superior to lidocaine (RR = 0.18 [95% CI = 0.08-0.44]; I2 = 31%). CONCLUSIONS: Calcium channel blockers performed well regarding the healing of CAF when compared to others in long-term follow-up. The superiority of botulinum toxin was not evidenced compared to topical treatments. More studies are needed to better assess recurrence rates.

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-Cov-2) has led to the elaboration of multiple studies to increase knowledge and understanding, hence, having the ability to accomplish an adequate and timely diagnosis and give an optimal treatment according to the patient's condition. The clinical manifestations of COVID-19 pose a series of challenges both in understanding and delimiting the disease secondary to the SARS-CoV-2 infection. This is due to the fact that the main axis of this disease is the endothelial compromise and the production of a "cytokine storm," triggering multiple organ failure and death. Given that a complete understanding of its pathophysiology and clinical behavior has not yet been achieved, we wondered if coinfection with other respiratory viruses modifies its performance and outcomes described so far. A literature search was performed, obtaining 68 articles, of which 25 were analyzed. The analysis showed us that there is a high variety both in the types of associated infections and in the clinical behavior of patients and their outcomes. Therefore, we consider that the search for other infections should be performed exhaustively, especially in those cases that may be susceptible to treatment such as Influenza A, human immunodeficiency virus, or bacterial infections. As well as optimize the analysis of these cases and establish if there are characteristics that allow establishing the possibility of carrying an additional infection to that of SARS-CoV-2 and the implications for the management and prognosis of the patient.

BACKGROUND: The overall estimated prevalence of rheumatoid arthritis (RA) in Mexico is 1.6%, but there are major variations in different geographic areas of the country. OBJECTIVE: This study aimed to determine the impact of individual and regional variables on the geographic distribution of RA in Mexico. METHODS: This multilevel analysis used data from a cross-sectional study that investigated the prevalence of RA among 19,213 individuals older than 18 years throughout 5 geographic regions in Mexico. Logistic regression models were used to determine predictors of RA, including individual and regional variables as well as cultural factors. Adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were determined. RESULTS: The prevalence of RA varied from 0.77% to 2.8% across the 5 regions. Individual factors associated with RA were sex (OR, 2.32; 95% CI, 1.74-3.07), previous medical diagnosis of RA ( OR 3.3, 95%CI: 29195.1 [corrected]), disability (OR, 2.07; 95% CI, 1.48-2.93), and the 56- to 65-year age group (OR, 1.95; 95% CI, 1.08-3.74). The regional factor of speaking an indigenous language had an OR of 2.27 (95% CI, 1.13-4.55). CONCLUSIONS: Various individual and regional factors were associated with variations in the prevalence of RA in the Mexican population.

This topic review aims to present a global vision of multilevel analysis models' applicability to health research, explaining its theoretical, methodological, and statistical foundations. We describe the basic steps to build these models and examples of their application according to the data hierarchical structure. It ir worth noticing that before using these models, researchers must have a rationale for needing them, and a statistical evaluation accounting for the variance percentage explained by the observations grouping effect. The requirements to conduct this type of analysis depends on special conditions such as the type of variables, the number of units per level, or the type of hierarchical structure. We conclude that multilevel analysis models are a useful tool to integrate information, considering the complexity of the relationships and interactions involved in most health conditions, including the loss of independence between observation units.
Este trabajo tiene como objetivo presentar una mirada global de la aplicabilidad de los modelos de análisis multinivel en el ámbito de la investigación sanitaria. Ofrece información sobre los fundamentos teóricos, metodológicos y estadísticos y, además, menciona los pasos básicos para la construcción de estos modelos, y da ejemplos de su uso, según la estructura jerárquica de los datos. Cabe resaltar que, antes de utilizar estos modelos, se requiere contar con un soporte teórico sobre la necesidad de uso y una valoración estadística que dé cuenta del porcentaje de varianza explicada por el efecto de agrupación de las observaciones. Los requisitos para llevar a cabo este tipo de análisis dependen de condiciones especiales como el tipo de variables, la cantidad de unidades por nivel o el tipo de estructura jerárquica. Se concluye que los modelos de análisis multinivel son una herramienta útil para lograr la integración de información, dadas la complejidad de las relaciones y las interacciones que determinan la mayoría de las condiciones de salud, incluida la pérdida de independencia entre las unidades de observación.
RESUMO
BACKGROUND: The current SARS-CoV-2 pandemic has especially affected individuals living in conglomerate settings having poverty as common characteristic. However, evidence of the association between COVID-19 severity and social determinants is still scarce, particularly, for Latin American countries. The objective was to assess the effect of socioeconomic deprivation in the clinical severity of COVID-19 infection among different localities of Bogotá, Colombia. METHODS: Secondary analyses using data of SARS-CoV-2 infected cases in Bogotá from 6 March 2020 to 19 April 2020 were carried out. Direct and indirect indicators of deprivation at area level and individual demographic characteristics (age, sex and type of case) were included in the analyses. FINDINGS: 1684 COVID-19 cases were included in the study. There were 217 (12.9%; 95% CI 11.3 to 14.5) serious cases, of which 32.6% (95% CI 26.4 to 38.8) cases were deceased. In the multilevel logistic regression, age, sex (female), type of case (different of imported case), number of serious cases recorded the previous day and multidimensional poverty were associated with serious cases (median OR: 1.72, 95% CI 1.56 to 1.87). INTERPRETATION: This paper explored the association between COVID-19 severity and social determinants. Expressions of poverty were associated with more severe cases during first 2 months of pandemic. It is a clear syndemic for the joint presentation of COVID-19 and other comorbidities among more serious cases.

OBJECTIVE: To assess the impact of the COVID-19 pandemic on routine childhood vaccination coverage in Colombia by age group, rural/urban residence, state and vaccine type. DESIGN: Ecological study of official monthly vaccination records. SETTING: Vaccination records from the Colombian Ministry of Health (March-October 2019 and 2020). PARTICIPANTS: Aggregated data for Colombian children (<12 months, n=676 153; 12-23 months, n=700 319; and 5 years, n=734 295) participating in the Expanded Program on Immunization. MAIN OUTCOME MEASURES: Proportion of eligible population receiving vaccination. RESULTS: Vaccination coverage showed an overall decline of approximately 14.4% from 2019 to 2020 (2019 coverage=76.0, 2020 coverage=61.6%). The greatest reduction in proportion vaccinated was observed in children <12 months of age for pneumococcal vaccine (second dose) (2019 coverage=81.4%; 2020 coverage=62.2%; 2019-2020 absolute difference, 19.2%; 95% CI 14.8% to 23.7%). For children aged 12-23 months, the proportion vaccinated for yellow fever declined by 16.4% (12.4% to 20.9%) from 78.3% in 2019 to 61.8% in 2020. Among children 5 years of age, the biggest decrease occurred for the oral polio vaccine (second dose), with a difference of 11.4% (7.1% to 15.7%) between 2019 and 2020 (73.1% and 61.7% for 2019 and 2020). We observed a statistically significant effect on vaccine coverage in rural versus urban areas for children <12 months and 5 years of age. CONCLUSIONS: Reduced uptake of immunisations during the COVID-19 pandemic poses a serious risk of vaccine-preventable disease outbreaks. Colombia and other middle-income countries need to continue to monitor immunisation programme coverage and disease outbreaks at the national and subnational levels and undertake catch-up vaccination activities.

Introduction: The Hitnü indigenous people live in precarious sanitary conditions, with food insecurity and being victims of sociopolitical violence in Arauca, Colombia. In addition, it is possible that they may be affected by exposure to hydrocarbons found in oil. Objective: To identify the health outcomes of morbidity and mortality profiles of the Hitnü people that could be associated with the exposure to crude oil. Materials and methods: A cross-sectional study was carried out with Hitnü indigenous people, during February and March, 2021, time of drought. A household questionnaire was applied, and one individual to collect data from the environment around the house, occupations and other activities, as well as data from sociodemographic, signs, symptoms, and findings of a medical examination. The potential association with hydrocarbons was explored considering three groups: inhabitants in Arauca city, Aspejaná reserve (not exposed), and San José del Lipa and La Vorágine reserves (exposed by the Ele river and tributaries). With free listings, causes of death were explored. The study incorporated a rigorous intercultural management in all its components. Results: A total of 576 indigenous people from 16 settlements participated. The water consumed could serve as means of exposure to hydrocarbons. Health problems were very varied, including infectious and chronic diseases, malnutrition, and trauma. The masses on the neck were associated with residing in the ancestral reserves (PR = 3.86; CI95% 1.77-8.39), territories with potential exposure to crude-oil. The most relevant causes of death were homicide, tumors, and tuberculosis. Conclusion: For its possible association with exposure to hydrocarbons, it is a priority to start the intercultural study of lymphadenopathies in indigenous communities potentially exposed to crude oil.
Introducción. El pueblo hitnü vive en condiciones sanitarias precarias, con inseguridad alimentaria y víctima de la violencia sociopolítica en Arauca (Colombia). Además, se sospecha que pueden estar afectados por la exposición a los hidrocarburos del petróleo. Objetivo. Identificar los eventos de salud del perfil de morbilidad y mortalidad de los indígenas hitnü que podrían asociarse con la exposición a petróleo crudo. Materiales y métodos. Se realizó un estudio transversal con indígenas hitnü, durante febrero y marzo de 2021, época de sequía. Se aplicó un cuestionario de hogares y uno individual para recolectar datos del ambiente peridomiciliario, ocupaciones y otras actividades, así como datos sociodemográficos, signos, síntomas y hallazgos de un examen médico. La potencial asociación con los hidrocarburos se exploró considerando tres grupos, según su localización: cabecera de Arauca, resguardo Aspejená (no expuestos) y resguardos de San José del Lipa y La Vorágine (expuestos por su cercanía al río Ele y afluentes). Con listados libres, se exploraron las causas de muerte. El estudio incorporó un riguroso manejo intercultural en todos sus componentes. Resultados. Participaron 576 indígenas de 16 asentamientos. El agua consumida pudo servir como medio de exposición a los hidrocarburos. Los problemas de salud fueron muy variados e incluían enfermedades infecciosas y crónicas, malnutrición y trauma. Las masas en el cuello se asociaron con residir en los resguardos ancestrales (RP=3,86; IC95% 1,77-8,39), territorios potencialmente expuestos al petróleo. Las causas de muerte más relevantes fueron el homicidio, los tumores y la tuberculosis. Conclusión: Por su posible asociación con los hidrocarburos, es prioritario el estudio intercultural de linfoadenopatías entre indígenas potencialmente expuestos al petróleo.

OBJECTIVE: To estimate the prevalence of musculoskeletal (MSK) disorders and to describe predicting variables associated with rheumatic diseases in 5 regions of México. METHODS: This was a cross-sectional, community-based study performed in 5 regions in México. The methodology followed the guidelines proposed by the Community Oriented Program for the Control of the Rheumatic Diseases (COPCORD). A standardized methodology was used at all sites, with trained personnel following a common protocol of interviewing adult subjects in their household. A "positive case" was defined as an individual with nontraumatic MSK pain of > 1 on a visual analog pain scale (0 to 10) during the last 7 days. All positive cases were referred to internists or rheumatologists for further clinical evaluation, diagnosis, and proper treatment. RESULTS: The study included 19,213 individuals; 11,602 (68.8%) were female, and their mean age was 42.8 (SD 17.9) years. The prevalence of MSK pain was 25.5%, but significant variations (7.1% to 43.5%) across geographical regions occurred. The prevalence of osteoarthritis was 10.5%, back pain 5.8%, rheumatic regional pain syndromes 3.8%, rheumatoid arthritis 1.6%, fibromyalgia 0.7%, and gout 0.3%. The prevalence of MSK manifestations was associated with older age and female gender. CONCLUSION: The prevalence of MSK pain in our study was 25.5%. Geographic variations in the prevalence of MSK pain and specific diagnoses suggested a role for geographic factors in the prevalence of rheumatic diseases.

OBJECTIVE: Rheumatic diseases are vastly underdiagnosed and undertreated, particularly among minorities and those of low socioeconomic status. The WHO-ILAR Community Oriented Program in the Rheumatic Diseases (COPCORD) advocates screening of musculoskeletal complaints in the community. The objective of this study was to evaluate the performance of the COPCORD Core Questionnaire (CCQ) as a diagnostic tool for rheumatic diseases. METHODS: We conducted a cross-sectional study designed in parallel with a large COPCORD survey in Mexico. A subsample of 17,566 questionnaires, selected from 4 of the 5 states included in a national COPCORD survey were included in the analysis as a diagnostic test to evaluate sensitivity, specificity, receiver operating characteristics curve (ROC), and positive likelihood ratio (LR+) of the CCQ as a case-detection tool for rheumatic diagnosis and for the most frequent diagnoses identified in the survey, osteoarthritis, regional rheumatic pain syndromes, and rheumatoid arthritis (RA). Logistic regression with the questions with LR+ ≥ 1 was performed to identify the strength of association (OR) for each question. RESULTS: Pain in the last 7 days, high pain score (> 4), and previous diagnosis were the questions with highest LR+ for diagnosis, and for diagnosis of RA treatment with NSAID. The variables that contributed most to the model were pain in the last 7 days (OR 2.0, 95% CI 1.8-2.3), NSAID treatment (OR 3.3, 95% CI 3.0-3.7), a high pain score (OR 1.15, 95% CI 1.13-1.17), and having a previous diagnosis (OR 1.4, 95% CI 1.3-1.6). These 4 questions had R(2) = 0.24, p < 0.01, for detection of any rheumatic diagnosis. The single variable that explains 16% (OR 1.33, 95% CI 1.31-134) of variance was a high pain score in the last 7 days. CONCLUSION: Some variables were identified in the CCQ that could be combined in a brief version for case detection of rheumatic diseases in community surveys. The validity of this proposal has to be tested against the original version.

Multimorbidity (MM) prevalence among older adults is increasing worldwide. Variations regarding the socioeconomic characteristics of the individuals and their context have been described, mostly in high-income settings. However, further research is needed to understand the effect of the coexistence of infectious diseases along with socioeconomic factors regarding MM. This study aims to examine the variation of MM regarding infectious diseases mortality after adjusting for socioeconomic factors. A cross-sectional multilevel study with a nationally representative sample of 17,571 Colombian adults of 60 years of age or older was conducted. Individual socioeconomic, demographic, childhood and health related characteristics, as well as group level variables (multidimensional poverty index and infectious diseases mortality rate) were analyzed. A two-level stepwise structural equation model was used to simultaneously adjust for the individual and contextual effects. Multimorbidity prevalence was 62.3% (95% CI 61.7-62.9). In the multilevel adjusted models, age, female sex, having functional limitations, non-white ethnicity, high body mass index, higher income, physical inactivity and living in urban areas were associated with multimorbidity among the sample for this study. The median odds ratio for multidimensional poverty was 1.18 (1.16-1.19; p = 0.008) and for infectious diseases was 1.25 (1.22-1.28; p = 0.014). This paper demonstrates that MM varies regarding the mortality of infectious diseases and shows a strong association between MM and poverty in a low-middle income country. Differences in the factors involved in the etiology of multimorbidity are expected among wealthy and poor countries regarding availability and prioritization of health services.

The great concern stemming from the current COVID-19 pandemic has been a challenge for governments and international organizations around the world. Likewise, the diagnosis has played an important role in the prioritization processes, in particular, for the identification and follow-up of cases. In this context, PCR and serological tests have become the international standard; however, some limitations, as well as the scope of these techniques, must be understood in terms of population numbers. This comment seeks to clarify the interpretation of the results of these tests from a public health perspective.

INTRODUCTION: More than 90% of children infected with COVID-19 worldwide developed mild to moderate disease. In Colombia, during 2020, COVID-19 infections in children stayed below 9.2% of the total cases, with no trends for age group or sex. OBJECTIVE: To estimate the incidence of acute respiratory symptoms and COVID-19 in children from public schools in Bogotá, Colombia during the second semester of 2020. MATERIAL AND METHODS: A telephone survey was conducted in over 5,000 scholar children. Antecedents and use of health services were informed. Descriptive statistics were used. RESULTS: A total of 151.470 persons per day accounting for an IR of 157,8 per 100,000 people; almost three times the rate reported by the official surveillance system in the city. CONCLUSION: A lack of diagnosis and consultation in children was found compared to the general population. Further research is needed to elucidate the true burden of the disease in children.

Amid the global pandemic crisis, international concern has centered on the control and prevention measures aimed at reducing the speed of the virus transmission while a more radical sanitary measure, such as vaccines, is achieved. Governmental and social efforts have had great impact on various sectors of society and their consequences have exceeded the sphere of health. This essay discusses the scope of specific measures in the sense of the appropriation of risk control measures and proposes the epidemiological method as an alternative that goes beyond the quantification of risks and the attribution of responsibilities. To conclude, the emphasis is placed on the need to promote information about socialization processes to better understand the consequences of individual acts favoring alternatives other than pandemic control based on the use of coercive measures.
En medio de la crisis pandémica a nivel global, la preocupación internacional ha girado en torno a la adopción de medidas de control y prevención orientadas a la reducción de la velocidad de propagación del virus en espera de que se disponga de una medida sanitaria radical como la vacuna. El esfuerzo gubernamental y social ha tenido un gran impacto en diversos sectores de la sociedad y las consecuencias han superado el ámbito sanitario. En este ensayo se discute su alcance en el sentido de la apropiación de las medidas de control del riesgo y se propone el método epidemiológico como una alternativa que va más allá de la cuantificación de los riesgos y la atribución de responsabilidades. Por último, se plantea la necesidad de fomentar procesos de socialización de la información que ayuden a la comprensión de las consecuencias de los actos individuales y favorezcan la superación de la expectativa de control pandémico únicamente basada en el uso de medidas coercitivas.

Introduction: Rapid IgM-IgG combined antibody tests can play an important role in the COVID-19 surveillance by supporting the diagnosis of infection, assessing the immune response, and verifying the progress towards herd immunity. Objective: To evaluate the performance of rapid IgM-IgG combined antibody tests in COVID-19 occupational surveillance in a group of Colombian enterprises. Materials and methods: We used the occupational surveillance data from companies that had performed periodic serological tests on all personnel from the end of April to the beginning of July, 2020. Workers were organized in small groups ("social bubbles") to prevent outbreaks and optimize surveillance. The sensitivity was estimated as if the sampling had a prospective design. We describe here the changes in serological testing through periodic rounds. Results: Data were obtained from 4,740 workers, of whom only 23 were symptomatic showing changes from IgM(-)/IgG(-) to IgM(+) and then to IgM(+)/IgG(+) and IgG(+). The sensitivity was 40.94% for IgM(+) and 47.95% for IgM(+)/IgG(+). This implies that a little less than half of the cases can be detected. Conclusion: Antibody rapid tests have a role in the diagnostic process of infection and they must be evaluated taking into account the moment of the epidemic, the type of test purchased, and the populations at risk since their results depend on the number of infections and cases. In the context of a health crisis, they can be optimized by organizing workers into "social bubbles"
Introducción. Las pruebas combinadas de IgM e IgG rápidas pueden tener un papel importante en la vigilancia de la COVID-19 y en su diagnóstico, así como en la evaluación de la respuesta inmunológica y la verificación de los avances hacia la inmunidad de rebaño. Objetivo. Evaluar el desempeño de las pruebas rápidas de anticuerpos en la vigilancia ocupacional de la COVID-19 en un grupo de empresas colombianas. Materiales y métodos. Se usaron datos de la vigilancia ocupacional de empresas que hicieron pruebas serológicas periódicas a todo el personal desde finales de abril hasta comienzos de julio de 2020. Los trabajadores laboraban en grupos pequeños ("burbujas sociales") para evitar brotes y optimizar la vigilancia. La sensibilidad se estimó como si el muestreo respondiera a un diseño prospectivo. Se describieron, asimismo, los cambios en las pruebas serológicas por medio de rondas periódicas. Resultados. Se obtuvieron datos de 4.740 trabajadores, de los cuales solo 23 eran sintomáticos. En ellos se evidenciaron cambios de IgM(-)/IgG(-) a IgM(+), y luego a IgM(+)/IgG(+) e IgG(+). La sensibilidad fue de 40,94 % para las IgM(+) y 47,95 % para las IgM(+)/IgG(+), lo que implica que se pudo detectar un poco menos de la mitad de los casos. Conclusión. Las pruebas rápidas de anticuerpos tienen un papel en el proceso diagnóstico de la infección y deben evaluarse teniendo en cuenta el momento de la epidemia, el tipo de prueba comprada y las poblaciones de riesgo, dado que sus resultados dependen del número de contagios y de casos. En el contexto de la presente crisis sanitaria pueden optimizarse si se organizan los trabajadores en "burbujas sociales".

Introduction: Public health surveillance together with good sanitary decisions is essential for the proper management of the SARS-CoV-2 pandemic. Objective: To compare the performance of Colombian departments based on the quality of the data and to build the national ranking. Materials and methods: We analyzed the accumulated cases published between March 6 and September 1, 2020, by the Instituto Nacional de Salud. To achieve comparability, the analyses considered the day the first case was diagnosed as the first analysis date for each department. The fulfillment of Benford's law was assessed with p-values in the log-likelihood ratio or chi-square tests. The analysis was completed with the lethality observed in each department and then the performance ranking was established. Results: Bogotá and Valle del Cauca had optimal public health surveillance performance all along. The data suggest that Antioquia, Nariño, and Tolima had good containment and adequate public health surveillance after the economic opening beginning on June 1, 2020. Conclusion: We obtained the ranking of the departments regarding the quality of public health surveillance data. The best five departments can be case studies to identify the elements associated with good performance.
Introducción. La vigilancia en salud pública y las decisiones sanitarias recomendadas son fundamentales para el manejo adecuado de la pandemia de SARS-CoV-2. Objetivo. Hacer una evaluación comparativa del desempeño de los departamentos colombianos de este atributo del sistema de vigilancia con base en la calidad de los datos y construir la clasificación nacional según el desempeño. Materiales y métodos. Se analizaron los casos acumulados publicados por el Instituto Nacional de Salud entre el 6 de marzo y el 1° de septiembre de 2020. Para la comparación, los análisis consideraron el día en que se diagnosticó el primer caso como la primera fecha de análisis de cada departamento. El cumplimiento de la ley de Benford se evaluó con los valores de p en las pruebas de razón del logaritmo de la verosimilitud o ji al cuadrado. Se completó el análisis del atributo de calidad del dato con la letalidad observada en cada departamento, y se estableció la clasificación según el desempeño. Resultados. La ciudad de Bogotá y el departamento del Valle del Cauca tuvieron un desempeño óptimo en la vigilancia en salud pública durante todo el periodo observado. Los datos sugieren que los departamentos de Antioquia, Nariño y Tolima tuvieron una buena contención y una adecuada vigilancia en salud pública después de la apertura económica iniciada el 1° de junio de 2020. Conclusión. Se obtuvo una clasificación de los departamentos y de Bogotá según la calidad de los datos de vigilancia en salud pública.

Introduction: The COVID pandemic is a challenge for public health surveillance and an opportunity to assess its strengths and weaknesses to improve the response. Objective: To evaluate the performance of the Colombian public health surveillance system during the first 50 days of the COVID-19 pandemic in the country. Materials and methods: We analyzed the data published between March 6 and April 24, 2020, by the Instituto Nacional de Salud and the World Health Organization (WHO). We evaluated: i) the quality of the data according to the fulfillment of Benford's law, and ii) the timeliness of the information measured as the difference in dates between the data generated by the Instituto Nacional de Salud and WHO's situational reports. We assessed the fulfillment of Benford's law using the p values of the log-likelihood ratio, the chi square or Moreno's exact tests. Results: Until April 24 there were 4,881 cases of COVID-19 in Colombia. During most of the first 50 days of the pandemic, Benford's law was fulfilled except the first days of the epidemic. The difference between Instituto Nacional de Salud and WHO reports largely depends on the different reporting times. Conclusion: In general, the Colombian public health surveillance system fulfilled Benford's law suggesting that there was quality in the data. Future studies comparing the performance of the departments and districts will improve the diagnosis of the Colombian surveillance system.
Introducción. La pandemia de COVID es un desafío para la vigilancia en salud pública y una oportunidad para evaluar sus fortalezas y debilidades en aras de mejorar la respuesta. Objetivo. Evaluar el desempeño del sistema de vigilancia en salud pública colombiano durante los primeros 50 días de la pandemia de COVID-19 en el país. Materiales y métodos. Se analizaron los datos publicados entre el 6 de marzo y el 24 de abril de 2020 por el Instituto Nacional de Salud y la Organización Mundial de Salud (OMS). Se consideraron en la evaluación: i) la calidad de los datos según la ley de Benford y ii) la oportunidad de la información, medida como la diferencia en fechas entre los datos generados en el Instituto Nacional de Salud y los recogidos en el informe situacional de la OMS. La variabilidad en el cumplimiento de la ley de Benford se evaluó con los valores de p en las pruebas de razón del logaritmo de la verosimilitud, ji al cuadrado o exacta de Moreno. Resultados. Hasta el 24 de abril hubo 4.881 casos de COVID-19 en Colombia. En la mayoría de los primeros 50 días se cumplió la ley de Benford, excepto en los primeros días de la epidemia. La diferencia entre los informes del Instituto Nacional de Salud y la OMS ha dependido, en gran medida, de la diferencia en los horarios de cierre de la información. Conclusión. En general, el sistema de vigilancia en salud pública colombiano cumplió con la ley de Benford, lo cual sugiere que hubo calidad en los datos. En futuros estudios que comparen el desempeño de los departamentos y distritos se podrá mejorar el diagnóstico de la vigilancia en salud pública del país.

OBJECTIVES: The objectives of the study were to estimate the prevalence of different clinical signs of trachoma and identify possible factors associated with TF. METHODOLOGY: Following the approval of the study protocol by the ethics committee, a cross-sectional study was conducted in Vaupés, a department of the Colombian Amazon, between the years 2012 and 2013 in two districts. Based on the records obtained from a standardized format for the clinical evaluation of the participants and the factors associated with follicular trachoma, an excel database was built and debugged, which was analyzed using IBM SPSS, Statistics Version 23 and Stata STATA (Version 14, 2015, StataCorp LLC, Texas, USA). RESULTS: The records of 13,091 individuals was collected from 216 rural indigenous communities, of which 12,080 were examined (92.3%); 7,274 in the Western and 4,806 in the Eastern districts. A prevalence of trachomatous inflammation-follicular (TF) of 21.7% (n = 599; 95% CI 20.2-23.3) in the Western and 24.9% (n = 483; 95% CI 23.1-26.9) in the Eastern district was found in children aged 1 to 9 years. Regarding trachomatous trichiasis (TT), 77 cases were found, of which 14 belonged to the Western district (prevalence 0.3%, CI 95% 0.2-0.5) and 63 to the Eastern district (1.8%, CI 95% 1.4-2.4). Children aged between 1 to 9 years were significantly more likely to have TF when there was the presence of secretions on the face (OR: 3.2; 95% CI: 2.6-3.9). CONCLUSIONS: Trachoma is a public health problem in Vaupés that requires the implementation of the SAFE strategy (S = Surgery, A = Antibiotics, F = Face Washing, E = Environment) in the Eastern and Western districts, for at least 3 consecutive years, in accordance with WHO recommendations.

This study aimed to identify the main regional factors associated with variations in the prevalence of functional limitation on the older adult in Colombia adjusted by individual characteristics. This multilevel study used cross-sectional data from 23,694 adults over 60 years of age in the SABE, Colombia nationwide survey. State-level factors (poverty, development, inequity, violence, health coverage, and access to improved water sources), as well as individual health related, socioeconomic and demographic characteristics, were analyzed. The overall prevalence of functional impairment for the basic activities of daily living (ADL) was 22%. The presence of comorbidities, low educational level, physical inactivity, no participation in social groups, mistreatment and being over 75 years old were associated with functional limitation. At the group level, the analysis showed significant differences in the functional limitation prevalence across states, particularly regarding the socioeconomic status measured according to the Human Development Index (median OR = 1.22; 95%CI: 1.13-1.30; p = 0.011). This study provides evidence on the impact of socioeconomic variation across states on FL prevalence in the Colombian elderly once adjusted for individual characteristics. The findings of this study, through a multilevel approach methodology, provide information to effectively address the conditions that affect the functionality in this population through the identification and prioritization of public health care in groups with economic and health vulnerability.
