RESUMEN

The objective of this study was to evaluate the knowledge level and perception of dengue fever management among Peruvian physicians and to determine the factors associated with higher knowledge. We conducted an analytical cross-sectional study based on an online survey. To evaluate the factors associated with a high level of knowledge (≥70% of correct answers), we used crude (cPR) and adjusted (aPR) prevalence ratios by the Poisson regression model. Of 359 respondents (median age: 33 years; male: 56.5%), 78.8% achieved a high level of knowledge. Multivariable analysis showed an independent association with having read the Peruvian clinical practice guidelines for dengue management (aPR: 1.29; 95% CI: 1.12-1.49), having experience in treating patients (aPR: 1.32; 95% CI: 1.03-1.68), and having treated cases frequently (aPR: 1.22; 95% CI: 1.02-1.46). Residing in the eastern macroregion (aPR: 0.83; 95% CI: 0.71-0.97) was associated with a low level of knowledge. In conclusion, Peruvian physicians had a high level of knowledge about dengue fever. This was associated with having clinical experience in dengue management. However, given the low level of knowledge in the eastern macroregion, educational campaigns are necessary in this area.

RESUMEN

Introduction: An association between weight status and migraine has been previously reported; however, this relationship has only been studied in adults, not in the paediatric population. Objective: To evaluate the association between weight status and migraine in the paediatric population. Methods: We searched PubMed/Medline, Scopus, Web of Science, Ovid Medline, and Embase using a cut-off date of May 2023. We included observational studies that evaluated the association between weight status (underweight, overweight, obese, and excess weight) and migraine in the paediatric population (children and adolescents). Normal weight was the comparator. The outcome was migraine (all types, episodic and chronic). We performed meta-analyses using a random-effects model to estimate the pooled effects for each outcome. Sensitivity analysis was performed based on study design and risk of bias (using the Newcastle-Ottawa Scale). Certainty of evidence was assessed using the GRADE approach. Results: Eight studies (6 cross-sectional, 1 case-control and 1 cohort) covering 16,556 patients were included. The overall certainty of evidence was very low for the association between overweight, obesity, and excess weight with migraine. In the sensitivity analysis, meta-analyses of studies with a low risk of bias found that the overweight population probably had an increased odds of migraine (OR: 1.70; 95% CI: 1.14 to 2.53; I2 = 32.3%, p = 0.224) and that excess weight may increase the odds of migraine (OR: 1.58; 95% CI: 1.06 to 2.35; I2 = 83.7%, p = 0.002). Additionally, cohort and case-control studies found that obesity probably increases the odds of migraine. No studies analysed the association between underweight and migraine. Conclusion: The associations between overweight, obesity, excess weight and migraine were uncertain, but studies with better methodological quality reported increased odds. Future longitudinal studies with proper confounding control are needed to disentangle their causal relationship. Systematic review registration: PROSPERO, identifier CRD42021271533.

Objective: To evaluate the scientific production of Peruvian health institutes in Scopus, 2010-2022. Methods: We conducted a Bibliometric study in Scopus during September 2022, in 14 public specialized health institutes of Peru. We included original studies with at least one author from one of the institutes. Results: The institutes included published between 0 and 347 original articles (H-index between 0 and 51). The institutes in the city of Lima were the ones with the highest production. In the seven institutes with the highest production, the percentage of articles with a corresponding author from the institute evaluated ranged from 22.3% to 36.7%, and the percentage of studies that reported being financed by the institute ranged from 0% to 11.6%. Conclusion: The scientific production of the evaluated institutes was heterogeneous, with a predominance of those located in Lima. The institutes rarely participated in the financing of the published studies.

RESUMEN

BACKGROUND: Despite the proven efficacy and safety of COVID-19 vaccines, pediatric vaccination coverage remains low in many countries. There are still doubts and fears in parents about vaccination in their children under 12 years of age. AIM: To evaluate the perceptions and intention of parents to vaccinate their children under 12 years of age. METHODS: Analytical cross-sectional study based on an online survey that evaluated the parents' perceptions regarding the risk of COVID-19 infection, the need for a vaccine, and the vaccine adverse events in their children under 12 years. We assessed the factors associated with the intention to vaccinate through crude (cPR) and adjusted prevalence rates (aPR), with confidence interval of 95% (CI 95%). RESULTS: 83.5% of respondents had the intention to vaccinate their children under 12 years of age. In the multivariate analysis, the factors associated with a decrease in the intention to vaccinate were to believe that the vaccine was not necessary (aPR 0.65; 95% CI 0.44 - 0.94), that it would not protect (aPR: 0.14; 95% CI 0.03 - 0.63), it would not be safe (aPR: 0.80; 95% CI 0.70 - 0.92) and it would cause long-term side effects (aPR: 0.92; 95% CI 0.85 - 1.00). On the other hand, living on the highlands or jungle was associated with an increase in the intention. CONCLUSION: In Peru, 16.5% of parents would not vaccinate their children under 12 years of age, because they perceived that the vaccine was not necessary and would not protect against COVID-19. In addition, they expressed concerns about the development of possible adverse events.

RESUMEN

INTRODUCCIÓN: A pesar de la probada eficacia y seguridad de las vacunas contra la COVID-19, la cobertura de vacunación pediátrica sigue siendo baja en muchos países. Aún existen dudas y temores en los padres sobre la vacunación en sus hijos bajo 12 años de edad. OBJETIVO: Evaluar las percepciones e intención de los padres de vacunar a sus hijos bajo 12 años en Perú. METODOLOGÍA: Estudio transversal analítico, a partir de una encuesta que recopiló la percepción de los padres sobre el riesgo de contagio por COVID-19, necesidad de vacunación y desarrollo de eventos adversos por la vacuna en niños bajo 12 años. Evaluamos los factores asociados a la intención de vacunación mediante razones de prevalencia crudas (RPc) y ajustadas (RPa) con intervalos de confianza al 95% (IC 95%). RESULTADOS: El 83,5% de los padres tenían la intención de vacunar a sus hijos bajo 12 años. En el análisis multivariado, los factores asociados a una disminución de la intención de vacunación fueron pensar que la vacuna no es necesaria (RPa: 0,65; IC 95% 0,44 - 0,94), que no protegería (RPa: 0,14; IC 95% 0,03 - 0,63), que no sería segura (RPa: 0,80; IC 95% 0,70 - 0,92) y que ocasionaría efectos negativos a largo plazo (RPa: 0,92; IC 95% 0,85 - 1,00). Por otro lado, residir en la Selva (RPa: 1,09; IC 95%: 1,03-1,15) o en la Sierra (RPa: 1,06; IC 95%: 1,00-1,11) se asoció a una mayor prevalencia de intención. CONCLUSIONES: En Perú, un 16,5% de padres no vacunaría a sus hijos bajo 12 años, ya que perciben que la vacuna no es necesaria y no protegería contra la COVID-19, además de tener la preocupación de posibles eventos adversos.

RESUMEN

OBJECTIVE: To evaluate the factors associated with the intention to participate in COVID-19 vaccine clinical trials in the Peruvian population. METHODS: Cross-sectional study and secondary analysis of a database that involved Peruvian population during September 2020. The Poisson regression model was used to estimate the associated factors. RESULTS: Data from 3231 individuals were analyzed, 44.1% of whom intended to participate in COVID-19 vaccine clinical trials. Factors associated with the outcome were being male (RPa: 1.25; 95% CI: 1.15-1.35), being from the highlands region (RPa: 1.18; 95% CI: 1.09-1.28) or jungle (RPa: 1.30; 95% CI: 1.15-1.47), having a relative that is a healthcare professional (PRa: 1.16; 95% CI: 1.06-1.28), using a medical source of information (PRa: 1.28; 95% CI: 1.17-1.41), and trusting in the possible effectiveness of vaccines (PRa: 1.40; 95% CI: 1.29-1.51). The main reason for not participating in the trial was the possibility of developing side effects (69.80%). CONCLUSION: There is an urgent need to generate a perception of safety in COVID-19 vaccine clinical trials, to increase the population's intention to participate in these studies, and to provide evidence-based information about the vaccine.

RESUMEN

OBJECTIVE: To determine the factors associated with prevention practices against COVID-19 in the Peruvian population according to rural vs. urban locations. METHODS: Analytical cross-sectional study, secondary analysis based on a previously collected database. A sample of individuals over 18 years of age, residing in Peru and with no history of COVID-19was evaluated. Factors associated with prevention practices were evaluated using Poisson regressions with variance adjustment by region cluster and stratified by rurality. RESULTS: Of 3231 participants included, 2741 (84.8%) were from urban areas and 490 (15.2%) from rural areas. The frequency of good prevention practices against COVID-19 was 27.8% in our total sample. In urban areas the frequency of good prevention practices was 28.8% and in rural areas it was 22.5%. Factors associated with prevention practices against COVID-19 in both urban and rural areas were male sex (urban: aPR 0.64, 95%CI 0.55-0.75; rural: aPR 0.66, 95%CI 0.54-0.80) and self-considering adequately carrying out prevention practices (urban: aPR 2.48, 95%CI 2.13-2.89; rural: aPR 2.70, 95%CI 2.27-3.19). CONCLUSION: The frequency of good prevention practices against COVID-19 was less than 30% in both urban and rural areas. There are differences in the factors associated with good preventive practice against COVID-19. Only sex and considering that preventive measures were adequately carried out were associated with good prevention practices in both areas. In view of this, prevention measures should be promoted taking into account cultural principles and considering geographical location in the face of present and future outbreaks or pandemics.

RESUMEN

Objetivo: Describir las prácticas de prevención y control para la infección por SARS-CoV2 en la población peruana. Material y Métodos: Estudio observacional de tipo descriptivo. Se evaluó una muestra no probabilística de adultos residentes en algún departamento de Perú. Las prácticas preventivas fueron evaluadas en personas sin antecedente de COVID-19 y las prácticas de control en personas que lo habían padecido. Resultados: Se evaluó un total de 3630 peruanos (edad media 25,4 ± 9,5) de los cuales el 3231 no indicaban el antecedente de COVID-19 y 399 refirieron haberlo padecido. Las medidas de prevención y control que se realizaron a menudo o siempre con mayor frecuencia fueron el utilizar mascarilla al salir de casa (97,9% vs 87,7), cubrirse su nariz y boca al estornudar o toser (95,4% vs 89,9%), guardar distancia de los demás en la calle (91,4% vs 74,7%), realizar el lavado de manos con agua y jabón al volver a casa (92,5% vs 88,7%), y desinfectar las superficies de objetos y lugares personales (82,6% vs 77,4%). El 22,1% y 83,7%, el 59,7% y 80,2, y el 8,0% y 16,8% consumieron algún tipo de medicamento, planta medicinal y dióxido de cloro para la prevención y control de la infección de COVID-19, respectivamente. Conclusiones: En general, menos del 50% de los participantes realizaron prácticas de prevención y control frente a la COVID-19 a menudo o siempre.

Objective: To describe prevention and control practices for SARS-CoV2 infection in the Peruvian population. Material and Methods: Observational descriptive study. A non-probabilistic sample of adults residing in a Peruvian department was evaluated. Preventive practices were evaluated in people with no history of COVID-19 and control practices in people who had had COVID-19. Results: A total of 3630 Peruvians were evaluated (mean age 25.4 ± 9.5) of whom 3231 did not indicate a history of COVID-19 and 399 reported having suffered from it. The prevention and control measures most frequently or always performed were using a mask when leaving home (97.9% vs 87.7%), covering their nose and mouth when sneezing or coughing (95.4% vs 89.9%), keeping their distance from others in the street (91.4% vs 74.7%), washing hands with soap and water when returning home (92.5% vs 88.7%), and disinfecting surfaces of objects and personal places (82.6% vs 77.4%). 22.1% and 83.7%, 59.7% and 80.2, and 8.0% and 16.8% consumed some type of medication, medicinal plant, and chlorine dioxide for prevention and control of COVID-19 infection, respectively. Conclusions: Overall, less than 50% of the participants performed prevention and control practices against COVID-19 often or always.

RESUMEN

INTRODUCTION: Peru is a developing country with increasing scientific production. However, it is necessary to understand the trends, impact, and collaborative networks of research to plan for policy improvements. OBJECTIVE: We analyzed the production, impact, and collaboration networks in the Peruvian scientific production between 2000 and 2019. METHODS: We did an observational analytical study. We searched Scopus for all the publications with at least one author with a Peruvian affiliation declared in the author byline. A descriptive analysis of the different characteristics, trends, and scientific collaboration was carried out. Collaboration networks were plotted using VOSviewer. RESULTS: Between 2000 and 2019, Peru had a total of 24 482 publications in scientific journals, with an average annual growth of 13.6%. Of the total, 70% of all the articles were cataloged as Clinical Medicine and Biomedical Sciences. Only half of the articles had a Peruvian affiliation. The countries with the largest share of collaboration were the United States and Brazil, and the articles with international collaboration had the highest number of citations per publication. CONCLUSIONS: Scientific production in Peru has increased in recent years, with a significant percentage of publications based on international collaboration and led by authors with non-Peruvian affiliations. It is necessary to strengthen collaboration ties between Peruvian and foreign institutions. Furthermore, it is essential to propitiate further research that will help solve the country's problems.

INTRODUCCIÓN: Perú es un país en vías de desarrollo, con una producción científica en aumento. Sin embargo, es necesario entender las tendencias, el impacto y la colaboración de sus investigaciones para promover una mejora continua de las mismas. OBJETIVO: Buscamos analizar la producción, el impacto y las redes de colaboración en la producción científica peruana entre los años 2000 y 2019. MÉTODOS: Realizamos un estudio analítico observacional haciendo una búsqueda en Scopus de todas las publicaciones que hayan tenido al menos un autor peruano en su filiación. Sobre eso, realizamos un análisis descriptivo de las diferentes características, tendencias y tipo de colaboración científica. Graficamos las redes de colaboración mediante VOSviewer. RESULTADOS: Entre los años 2000 y 2019, Perú tuvo un total de 24 482 publicaciones en revistas científicas, con un crecimiento anual promedio de 13,6%. Del total de artículos científicos, 70% de todas las publicaciones pertenecieron a las áreas de medicina clínica y ciencias biomédicas. Solo la mitad de los artículos contaban con filiación peruana. Los países con mayor colaboración fueron Estados Unidos y Brasil, y los artículos con colaboración internacional tuvieron mayor cantidad de citas por publicación. CONCLUSIONES: En años recientes, ha habido un incremento de la producción científica en Perú, con un gran porcentaje de publicaciones basadas en la colaboración internacional y lideradas por autores con filiación no peruana. Es necesario fortalecer lazos de colaboración entre instituciones peruanas y extranjeras. Además, es fundamental el incitar un mayor liderazgo en investigaciones que solucionen problemas del país.

RESUMEN

INTRODUCTION: The incidence of thyroid cancer has increased worldwide. Peru has few reports describing the national and regional epidemiology of thyroid cancer. OBJECTIVE: The incidence of thyroid cancer has increased worldwide. Peru has few reports describing the national and regional epidemiology of thyroid cancer. METHODS: A descriptive study of trends was conducted with secondary data obtained from a public information source in Peru. The ICD 10: C73.0 coding record was evaluated, by age group, year and region. The age-standardized prevalence (period 2005 to 2016) and mortality (period 2005 to 2015) were calculated by region and year of study. RESULTS: In the 2005-2016 period, 19 513 cases of thyroid cancer were recorded. The age group with the highest frequency was 30 to 59 years (57.7%). The prevalence increased from 4.7 to 15.2 cases per 100 000 inhabitants in the period 2005-2016, with the coastal region showing the greatest increase. Likewise, 1596 deaths from thyroid cancer (period 2005 to 2015) were recorded, more frequently in those older than 60 years (75.5%). The age-standardized mortality rate increased from 0.67 in 2005 to 0.72 in 2015, being the highlands the one with the greatest increase. CONCLUSIONS: The prevalence of thyroid cancer increased and mortality remained constant in the period studied. These results suggest exploring social and population factors that may have influenced these results. Likewise, population records of this and other neoplasms in Peru should be improved.

INTRODUCCIÓN: La incidencia de cáncer de tiroides se ha incrementado en el mundo. En Perú existen limitados informes que describan la epidemiología nacional y regional de esta neoplasia. OBJETIVO: Describir la tendencia de la prevalencia y mortalidad de cáncer de tiroides registrada en el Ministerio de Salud de Perú. MÉTODOS: Se realizó un estudio descriptivo de tendencias con datos secundarios, obtenidos de una fuente de información pública de Perú. Se evaluó el registro de codificación CIE 10: C73.0, por grupo de edad, año y región. Se calcularon las tasas estandarizadas de la prevalencia (periodo 2005 a 2016) y mortalidad (periodo 2005 a 2015) por regiones y año de estudio. RESULTADOS: Durante el periodo 2005-2016 se registraron 19 513 casos de cáncer de tiroides. El grupo etario con mayor frecuencia fue de 30 a 59 años (57,7%). La prevalencia incrementó de 4,7 a 15,2 casos por 100 000 habitantes en el periodo 2005-2016 y la región de la costa fue la que presentó mayor ascenso. Asimismo, se registraron 1596 muertes por cáncer de tiroides (periodo 2005 a 2015) con mayor frecuencia en mayores de 60 años (75,5%). La tasa estandarizada de mortalidad por 100 000 habitantes aumentó de 0,67 en 2005 a 0,72 en 2015, siendo la región de la sierra la de mayor incremento. CONCLUSIONES: La prevalencia por cáncer de tiroides aumentó y la mortalidad se mantuvo constante en el periodo estudiado. Estos resultados animan a explorar factores sociales y de la población que hayan podido influir en ello; además de mejorar los registros poblacionales de esta y otras neoplasias en Perú.
