Humoral response after a BNT162b2 heterologous third dose of COVID-19 vaccine following two doses of BBIBP-CorV among healthcare personnel in Peru.

Background: The inactivated virus vaccine, BBIBP-CorV, was principally distributed across low- and middle-income countries as primary vaccination strategy to prevent poor COVID-19 outcomes. Limited information is available regarding its effect on heterologous boosting. We aim to evaluate the immunogenicity and reactogenicity of a third booster dose of BNT162b2 following a double BBIBP-CorV regime. Methods: We conducted a cross-sectional study among healthcare providers from several healthcare facilities of the Seguro Social de Salud del Perú - ESSALUD. We included participants two-dose BBIBP-CorV vaccinated who presented a three-dose vaccination card at least 21 days passed since the vaccinees received their third dose and were willing to provide written informed consent. Antibodies were determined using LIAISON® SARS-CoV-2 TrimericS IgG (DiaSorin Inc., Stillwater, USA). Factors potentially associated with immunogenicity, and adverse events, were considered. We used a multivariable fractional polynomial modeling approach to estimate the association between anti-SARS-CoV-2 IgG antibodies' geometric mean (GM) ratios and related predictors. Results: We included 595 subjects receiving a third dose with a median (IQR) age of 46 [37], [54], from which 40% reported previous SARS-CoV-2 infection. The overall geometric mean (IQR) of anti-SARS-CoV-2 IgG antibodies was 8,410 (5,115 - 13,000) BAU/mL. Prior SARS-CoV-2 history and full/part-time in-person working modality were significantly associated with greater GM. Conversely, time from boosting to IgG measure was associated with lower GM levels. We found 81% of reactogenicity in the study population; younger age and being a nurse were associated with a lower incidence of adverse events. Conclusions: Among healthcare providers, a booster dose of BNT162b2 following a full BBIBP-CorV regime provided high humoral immune protection. Thus, SARS-CoV-2 previous exposure and working in person displayed as determinants that increase anti-SARS-CoV-2 IgG antibodies.

Post-vaccination seropositivity against SARS-CoV-2 in peruvian health workers vaccinated with BBIBP-CorV (Sinopharm).

OBJECTIVE: To estimate the prevalence of post-vaccination seropositivity against SARS-CoV-2 and identify its predictors in Peruvian Social Health Insurance (EsSalud) personnel in 2021. METHODS: We conducted a cross-sectional study in a representative simple stratified sample of EsSalud workers. We evaluated IgG anti-SARS-CoV-2 antibodies response (seropositivity) by passive (previous infection) and active immunization (vaccination), and epidemiological and occupational variables obtained by direct interview and a data collection form. Descriptive and inferential statistics were used with correction of sample weights adjusted for non-response rate, and crude and adjusted odds ratio (OR) and geometric mean ratio (GMR) with their respective 95% confidence intervals (95%CI) were estimated. RESULTS: We enrolled 1077 subjects. Seropositivity was 67.4% (95%CI: 63.4-71.1). Predictors of seropositivity were age (negative relation; p < 0.001), previous infection (aOR = 11.7; 95%CI: 7.81-17.5), working in COVID-19 area (aOR = 1.47; 95%CI: 1.02-2.11) and time since the second dose. In relation to antibody levels measured by geometric means, there was an association between male sex (aGMR = 0.77; 95%CI: 0.74-0.80), age (negative relation; p < 0.001), previous infection (aGMR = 13.1; 95%CI:4.99-34.40), non-face-to-face/licensed work modality (aGMR = 0.78; 95%CI: 0.73-0.84), being a nursing technician (aGMR = 1.30; 95%CI: 1.20-1.41), working in administrative areas (aGMR = 1.17; 95%CI: 1.10-1.25), diagnostic support (aGMR = 1.07; 95%CI: 1.01-1.15), critical care (aGMR = 0.85; 95%CI: 0.79-0.93), and in a COVID-19 area (aGMR = 1.30; 95%CI: 1.24-1.36) and time since receiving the second dose (negative relation; p < 0.001). CONCLUSIONS: Seropositivity and antibody levels decrease as the time since receiving the second dose increases. Older age and no history of previous infection were associated with lower seropositivity and antibody values. These findings may be useful for sentinel antibody surveillance and the design of booster dose strategies.

Perceived discrimination as a barrier for the adequate treatment of chronic diseases in Venezuelan migrants from Peru.

OBJECTIVE: To determine the association between perceived discrimination and receiving adequate treatment for chronic diseases in Venezuelan migrants. METHODOLOGY: A cross-sectional study was performed. This is a secondary analysis of the ENPOVE national survey from Peru. The association between the perceived discrimination and receiving adequate treatment for chronic diseases was evaluated using a Poisson regression model, considering the adjusted effect of the multistage sampling. RESULTS: A total of 865 migrants were evaluated (age: 36.6 ± 0.7 years and 58.2% women). Of these, 54.8% perceived discrimination, and 89.2% did not receive adequate treatment for chronic diseases. Perceived discrimination was significantly associated with a lower prevalence of receiving adequate treatment for chronic diseases (PRa = 0.49; 95%CI 0.25 - 0.97). CONCLUSION: This study evidenced that perceived discrimination decreases the prevalence of receiving adequate treatment for chronic diseases by approximately 50% compared with those who did not perceive discrimination.

Estudios transversales / Cross-sectional studies

Los estudios observacionales transversales pueden ser de tipo descriptivos o también analíticos dependiendo del objetivo general. Este diseño es rápido, económico y permite el cálculo directo de la prevalencia de una condición. Además, la relación de temporalidad entre la exposición y el efecto son medidas de forma simultánea en un único período, no siendo posible identificar una direccionalidad en la temporalidad. Cuando estos estudios persiguen un objetivo general analítico, la medida de asociación es la Razón de Prevalencias (RP), especialmente cuando la prevalencia del efecto es mayor o igual a 10% o el Odds Ratio (OR) cuando la prevalencia es baja. Para cuantificar esta asociación pueden utilizarse diferentes modelos de regresión como el binomial log o Poisson log, incluyendo los modelos lineales generalizados. Cuando la medida de asociación a utilizar es el OR, el modelo más comúnmente empleado es la regresión logística múltiple.

Cross-sectional studies are epidemiological design which can be considered as descriptive or analytical designs depending on the general objective. This is a quickly and economical design and allows to calculate the prevalence of a condition. Also, the relationship of temporality between the exposition and the outcome is being measured simultaneously on a unique period, not being possible to identify a directionality in the temporality. When there is an analytic objective, the association measure used is the Prevalence Ratio (PR), specially when the prevalence of the outcome is more or equal to 10% or the Odds Ratio (OR) when that prevalence is lower. To quantify this association different regression models like Binomial log or Poisson log can be used, including generalized lineal models. If the association measure is OR, the most common used model is the multiple logistic regression.

RESUMO: Objetivo: Determinar a associação entre a discriminação percebida e o recebimento de tratamento adequado para doenças crônicas em migrantes venezuelanos. Métodos: Foi realizado um estudo transversal. Esta é uma análise secundária da pesquisa nacional Venezuelan Population Residing in the Country Survey do Peru. A associação entre discriminação percebida e receber tratamento adequado para doenças crônicas foi avaliada por meio de um modelo de regressão de Poisson, considerando o efeito ajustado da amostra em múltiplos estágios. Resultados: Foram avaliados 865 migrantes (idade: 36,6 ± 0,7 anos e 58,2% mulheres). Destes, 54,8% perceberam discriminação e 89,2% não receberam tratamento para a doença crônica. A discriminação percebida foi significativamente associada à menor prevalência de receber adequado tratamento para doenças crônicas (razão de prevalência ajustada — RPa = 0,49, intervalo de confiança de 95% — IC95% 0,25 - 0,97). Conclusão: Este estudo mostrou que a discriminação percebida diminui a prevalência de receber adequado tratamento para doenças crônicas em 50%, em comparação com aqueles que não percebem a discriminação.

After SARS-CoV-2, will H5N6 and other influenza viruses follow the pandemic path?

While the world is focused on attending, controlling, and mitigating the current pandemic of COVID-19, caused by the SARS-CoV-2, other viral threats are possibly emerging and reemerging especially in Asia, posing a risk for the spread in that region and beyond. A predictable threat is the avian influenza virus, especially H5N6, which has recently led to significant outbreaks in China and the Philippines, deserving more attention and control. In the current review, we assess the history of this highly pathogenic reemerging virus, as well as the contemporary implications of poultry outbreaks occurring in some Asian countries. We also look at outbreaks due to other strains not only in Asia but also across Europe and Africa, according to recent reports from the World Organization of Animal Health (OIE).

Estudios de casos y controles / Case-Control Studies

Los estudios de casos y controles son estudios epidemiológicos observacionales analíticos utilizados generalmente para evaluar factores asociados a condiciones de presentación infrecuente. Su jerarquía dentro de la pirámide de evidencia se ubica en un lugar intermedio, generalmente con un nivel de evidencia considerado mayor que los estudios transversales analíticos y menor que los estudios de cohorte. La medida de asociación utilizada para estos estudios es el Odds Ratio (o razón de momios). Algunas variantes de este diseño como los estudios de casos y controles incidentes y los anidados (dentro de una cohorte) permiten disminuir el riesgo de sesgo de selección. Se revisan los conceptos básicos relacionados a este tipo de estudios.

Case-control studies are analytical observational epidemiological studies generally devoted to evaluate factors associated with infrequent diseases. Its hierarchy within the pyramid of evidence lies in an intermediate place between cross sectional and cohort studies. The measure of association used for these studies is the Odds Ratio. Some variants of this design, such as incident and nested case studies and nested case-control studies (within a cohort) can reduce the risk of selection bias. The basic concepts related to this type of studies are reviewed.

[Characteristics associated with pre travel medical consultation in tourists visiting Cuzco, Peru]. / Características asociadas a la consulta pre viaje en turistas que visitan Cusco, Perú.

BACKGROUND: International tourism is increasing. Preventive Medicine remains important, especially the Pre-Travel Consultation (PTC). OBJECTIVE: To determinate, the characteristics of tourists associated with PTC in tourists at Cuzco, Peru. METHODS: A cross-sectional, analytical study, a secondary analysis of data from a database generated by survey of foreign tourists who visited Cuzco, in the waiting room of the airport was performed. The main variable was to have had a PTC at the tourist's country of residence, the area of residence was categorized according to health/risk of acquiring infectious diseases as traveler's diarrhea during their stay. These and other variables were analyzed and statistical association with generalized linear models were done. RESULTS: Of the 1827 tourists, 875 (48%) were men, with a median age of 33 years (range 18-88 years); 42% had a PTC. In the multivariate analysis, it was found that a PTC lower frequency was associated with male gender (aPR: 0.84; 95% CI: 0.75-0.94), and a higher frequency was associated with have born (aPR: 1.77; 95% CI: 1.39-2.27) and reside in an area of low risk of acquiring infectious diseases (aPR: 1.95; 95% CI: 1.26-3.00), adjusted for the history of a disease. CONCLUSIONS: Sex, region of birth and residence of tourists (as risk of acquiring infectious diseases) are associated with having a PTC. These findings may serve the health and government attending tourists who come to our country.

Documentos de gestión en las sociedades científicas de estudiantes de medicina de Latinoamérica, 2014 / Management documents in medical students scientific societies in Latin America, 2014

Para determinar si las sociedades científicas afiliadas a la Federación Latinoamericana de Sociedades Científicas de Estudiantes de Medicina (FELSOCEM) poseen documentos de gestión y sus características según el tipo de sociedad, se realizó un estudio transversal analítico, durante la asamblea anual FELSOCEM, Córdoba-Argentina, 2014. Se obtuvo resultados estadísticos según dos características (tipo de universidad: pública/privada o el ser o no Federada -máxima categoría de la sociedad científica ante FELSOCEM-). De las 58 respuestas, muy pocos contaban con asesores específicos (25%), reglamentación para sus asesores (35%) y actividades societarias (43%). Al realizar en análisis, las sociedades de universidades privadas tuvieron menos frecuencia de reglamentación de los asesores (p=0,044) y de revisar periódicamente las funciones de los directivos (p=0,011). Las sociedades federadas tenían con más frecuencia asesores generales (p=0,012), revisaban periódicamente sus estatutos (p=0,038) y reglamentos (p=0,047).

Introducción: El turismo internacional continúa aumentando, siendo la medicina preventiva un pilar importante, como las consultas pre viaje (CPV). Objetivo: Determinar las características del turista asociadas a CPV en turistas que visitan Cusco. Materiales y Métodos: Estudio analítico transversal, de análisis de datos secundarios, a partir de una base de datos generada por encuesta aplicada a turistas extranjeros que visitaron el Cusco, en la sala de espera del aeropuerto. La variable principal fue haber tenido CPV en el país de residencia del turista. La zona de residencia se categorizó según la salubridad/riesgo de los turistas para adquirir enfermedades-infectocontagiosas como la diarrea del viajero durante su estadía. Estas y otras variables fueron analizadas y se obtuvieron estadísticos de asociación con los modelos lineales generalizados. Resultados: De los 1.827 turistas, 875 (48%) fueron hombres, con mediana de edad de 33 años (rango 18-88 años). El 42% tuvo una CPV. En el análisis multivariado, se encontró que estuvo asociado a una menor frecuencia de CPV el sexo masculino (RPa: 0,84; IC 95%: 0,750,94%), y a una mayor frecuencia de CPV el haber nacido (RPa: 1,77; IC 95%: 1,39-2,27) y residir en una zona de bajo riesgo para adquirir enfermedades infecciosas (RPa: 1,95; IC 95%: 1,26-3,00), ajustado por el antecedente de una enfermedad. Discusión: El sexo, la zona de nacimiento y residencia del turista (según riesgo de adquirir enfermedades infecciosas) son factores asociados a tener una CPV. Estos hallazgos pueden servir a las instituciones de salud y gubernamentales que atienden a turistas que vienen a nuestro país.

Pre-travel advice concerning vector-borne diseases received by travelers prior to visiting Cuzco, Peru.

Peru is an increasingly popular tourist destination that poses a risk to travelers due to endemic vector-borne diseases (VBDs). The objective of our study was to determine which factors are associated with receiving pre-travel advice (PTA) for VBDs among travelers visiting Cuzco, Peru. A cross-sectional secondary analysis based on data from a survey among travelers departing Cuzco at Alejandro Velazco Astete International Airport during the period January-March 2012 was conducted. From the 1819 travelers included in the original study, 1717 were included in secondary data analysis. Of these participants, 42.2% received PTA and 2.9% were informed about vector-borne diseases, including yellow fever (1.8%), malaria (1.6%) and dengue fever (0.1%). Receiving information on VBDs was associated with visiting areas endemic to yellow fever and dengue fever in Peru. The only disease travelers received specific recommendations for before visiting an endemic area for was yellow fever. Only 1 in 30 tourists received information on VBD prevention; few of those who traveled to an endemic area were warned about specific risks for infectious diseases prior to their trip. These important findings show that most tourists who travel to Peru do not receive PTA for the prevention of infectious and VBD, which can affect not only the travelers but their countries of origin as well.
