[Epidemiological profile of allergic respiratory disease in Mexican children]. / Perfil epidemiológico de la enfermedad respiratoria alérgica en niños mexicanos.

OBJECTIVE: Report the prevalence and severity of the most common allergic diseases in children living in Monterrey, México. METHODS: Cross-sectional multi-center survey on the most common allergic diseases, completed by parents of 6-7-year-old children and by 13-14- year-old adolescents in the Monterrey metropolitan area, between January 2018 and December 2019. RESULTS: A total of 3,044 questionnaires were eligible for the analysis. Among children between 6-7 years old, 30.2% (n = 143/473) presented wheezing at any time in their life; with a higher prevalence in the male population. In the adolescent group, 26.4% reported having experienced wheezing at some point in their life, with a slight predominance in the female group (54.9%). CONCLUSIONS: Knowing the prevalence of allergic diseases in our population gives us tools to generate strategies that allow us to provide the best quality healthcare to our patients.

[Asociación de exposición a humo de camiones en adolescentes con asma de un centro de referencia del noreste de México].

Objective: To compare whether adolescents who are exposed to truck smoke have a higher prevalence of asthma symptomatology versus those who are not exposed. Methods: A cross-sectional, descriptive, and comparative study. Adolescents aged 13 and 14 years were included and completed a self-report questionnaire. Subjects were selected following the same methodology as in ISAAC phase III. They underwent an epidemiological survey for the presence of symptoms. Ex- posure to truck smoke was defined as passing trucks most of the day as perceived by the patient. The distribution was assessed with the Kolmogorov-Smirnov test. Comparisons with Chi-square or Student's t-test, as appropriate. A value of p³0.05 was considered statistically significant. Results: A total of 492 patients were included. The demographic variables can be seen in Table 1. When performing the association between the groups of ad- olescents with asthma exposed to truck smoke, a significant difference was found in the prevalence of respiratory symptomatology and asthma (26.0% vs 9.6%, p=0.000) (Table 1). Conclusions: Adolescent patients with asthma who are exposed to truck smoke demonstrated a significant difference in the presence of respiratory symptom- atology and asthma compared to patients without exposure.

Objetivo: Comparar si los adolescentes que están expuestos a humo de camiones tienen mayor prevalencia de sintomatología de asma contra quienes no están expuestos. Métodos: Estudio transversal, descriptivo y comparativo. Se incluyeron adolescentes de 13 y 14 años de edad quienes completaron un cuestionario autoinfor- mado. Los sujetos se seleccionaron siguiendo la misma metodología que en la fase III de ISAAC. Se les realizó una encuesta epidemiológica para la presencia de síntomas. Exposición al humo de camiones se definió como el paso de camiones la mayoría del día a percepción del paciente. La distribución fue evaluada con la prueba de Kolmogórov-Smirnov. Comparaciones con prueba de Chi-cuadrada o T de Student, según corresponda. Un valor de p £ 0.05 fue considerado estadísticamente significativo. Resultados: Se incluyeron un total de 492 pacientes. Las variables demográficas se pueden observar en la Tabla 1. Al realizar la asociación entre los grupos de adolescentes con asma que se encuentran expuestos a humo de camiones se encontró una diferencia significativa en la prevalencia de sintomatología respira- toria y asma (26.0% vs 9.6%, p = 0.000). Conclusiones: Los pacientes adolescentes con asma que se encuentran expuestos al humo de camiones demostraron tener diferencia significativa en la presencia de sintomatología respiratoria y asma en comparación con los pacientes sin exposición.

Cardiovascular health worsening in patients with autoimmune rheumatological diseases during the COVID-19 pandemic.

Rheumatic autoimmune diseases are associated with a myriad of comorbidities. Of particular importance due to their morbimortality are cardiovascular diseases. COVID-19 greatly impacted the world population in many different areas. Patients with rheumatic diseases had to face changes in their healthcare, in addition to unemployment, a decrease in physical activity, social isolation, and lack of access to certain medications. This review summarizes the impact of COVID-19 pandemic on cardiovascular risk factors, comorbidities, and unhealthy behaviors in patients with rheumatic inflammatory autoimmune diseases, particularly focused on rheumatoid arthritis and systemic lupus erythematosus. Searches were carried out in MEDLINE/PubMed and Scopus from August to December 2022. Four reviewers screened the title and abstract of retrieved records. Potentially eligible reports were then reviewed in full text. Differences were reconciled by either consensus or discussion with an external reviewer. During the COVID-19 pandemic, patients with rheumatic diseases showed an increase in the prevalence of mental health disorders (43.2-57.7%), reduced physical activity (56.8%), and a worsening in eating behaviors. Alcohol intake increased (18.2%), especially in early phases of the pandemic. Smoking prevalence decreased (28.2%). Dyslipidemia and hypertension showed no changes. The pandemic and lockdown affected rheumatic patients not only in disease-related characteristics but in the prevalence of their cardiovascular comorbidities and risk factors. Lifestyle changes, such as healthy eating, physical activity, and optimal management of their rheumatic diseases and comorbidities, are essential to manage the long-lasting consequences of the COVID-19 outbreak. Key Points • During the COVID-19 pandemic, anxiety, depression, sedentarism, obesity, and a worsening in eating behaviors increased. •Patients with rheumatic diseases and comorbidities have worse clinical outcomes and a higher cardiovascular disease burden than those without them. •Comparative studies are necessary to precisely elucidate the pandemic's impact on the prevalence of cardiovascular disease, risk factors, and comorbidities in patients with rheumatoid arthritis and systemic lupus erythematosus.
