Resultados: Los casos de ERA aumentaron significativamente en los menores de 5 años en Envigado y Caldas (43,3% vs 29,6%) y en los de 65 y más años, en Medellín (13,2%) por cada incremento de 10 µg/m3 en PM2,5 al día quince a partir de la exposición. Conclusiones: Los eventos diarios respiratorios tuvieron especial frecuencia en Medellín y en municipios de la zona sur.
Introduction: The harmful effect of fine particulate matter on the respiratory health of child and elderly populations is a concern for public health. Objective: To establish the effect of pollution by less than 2.5 μm in diameter (PM2.5) particulate matter on Acute Respiratory Disease (ARD) during 2008-2015 in children younger than 5 and adults older than 65 from the Metropolitan Area of the Aburrá Valley (Colombia), adjusting for meteorological and climate variables. Materials and methods: Ecological study with information from the air quality surveillance network and individual records of health providers. Generalized Additive Models were developed using smoothing spline Poisson models. The assessment of the association and confidence intervals were calculated for each distributed lag. Results: For each 10 µg/m3 increment in PM2,5 and the day 15 post-exposure, ARD cases increased significantly in populations who are younger than 5 and older than 65 in Envigado and Caldas (43.3% vs. 29.6%) and Medellín (13.2%), respectively. Conclusions: Daily respiratory events had a special frequency in Medellín and the municipalities of the southern region.

Introduction: During the COVID-19 pandemic, women disproportionately assume more unpaid activities, affecting their employment. Objective: Describe the influence of COVID-19 on the employment of caregivers of children and adolescents from a gender perspective. Methods: Cross-sectional study in three high-complexity hospitals in Bogotá, Colombia from April 2020 to June 2021. A subsample of the FARA cohort was taken, including those patients with a positive test for SARS-COV2. We took as our analysis category children older than 8 years and younger than 18 years who had a positive SARS-COV2 test, as well as, caregivers of all children with a positive SARS-COV2 test. This subsample was drawn from the FARA cohort. A survey was applied to them. We carried out a descriptive and stratified analysis by age group, educational, and socioeconomic level. Results: We included 60 surveys of caregivers and 10 surveys of children. The main caregiver in 94.8% of the cases was a female. At the beginning of the pandemic, 63.3% of the caregivers were employed, and 78.9% of those lost their employment. The vast majority of these caregiver were women (96.6%, n = 29). A predominance of loss of work activity was documented in caregivers of children in early childhood 66.6% (n = 20), with lower education 66.6% (n = 20), and from lower strata 56.6% (n = 17). Conclusion: Caregivers of children with COVID-19 with low educational levels and lower socioeconomic conditions, as well as those with children under 5 years showed greater likelihood of employment loss between the interviewed subsample.
RESUMO
Background: Acute respiratory failure is a life-threatening medical condition, associated with a variety of conditions and risk factors, including acute respiratory diseases which are a frequent cause of pediatric morbidity and mortality worldwide. In Colombia, the literature related to ARF is scarce. Objective: To determine the incidence, causes, and sociodemographic and clinical characteristics of ARF in three hospitals in Bogota, a high-altitude city located in Colombia, during the COVID-19 pandemic. Methods: A multicenter prospective cohort study called the FARA cohort was developed between April 2020 - December 2021. Patients older than one month and younger than 18 years with respiratory distress who developed ARF were included. Results: 685 patients with respiratory distress were recruited in 21 months. The incidence density of ARF was found to be 41.7 cases per 100 person-year CI 95%, (37.3-47.7). The median age was 4.5 years.. Most of the patients consulted during the first 72â h after the onset of symptoms. Upon admission, 67.2% were potentially unstable. The most frequent pathologies were asthma, bronchiolitis, pneumonia, and sepsis. At admission, 75.6% of the patients required different oxygen delivery systems, 29,5% a low-flow oxygen system, 36,8% a high-flow oxygen system, and 9,28% invasive mechanical ventilation. SARS-COV-2, respiratory syncytial virus, rhinovirus/enterovirus, and adenovirus were the most frequently isolated viral agents. The coinfection cases were scarce. Conclusions: This multicenter study, the FARA cohort, developed at 2,600 meters above sea level, shows the first data on incidence, etiology, sociodemographic and clinical characterization in a pediatric population with ARF that also concurs with the COVID-19 pandemic. These results, not only have implications for public health but also contribute to the scientific and epidemiological literature on a disease developed at a high altitude.
RESUMO
INTRODUCTION: Respiratory syncytial virus (RSV) is one of the most important childhood infections. OBJECTIVE: To evaluate the effectiveness and safety of palivizumab immunoprophylaxis in preterm infants at a high risk of severe respiratory syncytial virus infection during the RSV season in Colombia. METHODOLOGY: A prospective observational non-comparative multicenter study in six Colombian cities. At the beginning of the RSV infection season, palivizumab prophylaxis, up to five doses, was administered to infants born at ≤32 weeks of gestation, infants younger than six months, infants under one year of age with bronchopulmonary dysplasia (BPD), infants one year or less of age with hemodynamically significant acyanotic and non-acyanotic congenital heart disease (CHD), and with follow-up during the immunoprophylaxis until one month after the last dose. RESULTS: The study enrolled 600 patients, 91.8% of which were born at ≤ 32 weeks of gestation. BPD was observed in 54.9% of infants. 49% were born at < 32 weeks gestation and presented BPD. 6.9% had hemodynamically significant acyanotic and non-acyanotic CHD 53.3% received three or more doses of palivizumab. The mean interval between doses was 39.6 days. 1.8% of patients were hospitalized due to a confirmed RSV infection. Overall mortality was 1.2%, whereas the mortality by RSV in infants undergoing prophylaxis was 0.2%. CONCLUSIONS: Palivizumab was a clinically effective, well-tolerated treatment in the Colombian population. The safety profile of palivizumab reflects the findings from previous studies in developed countries.

Talipes equinovarus, atrial septal defect, Robin sequence and persistent left superior vena cava (TARP) syndrome is a congenital disease caused by mutations in the RBBM10 gene. It has a low prevalence and a high rate of mortality in the neonatal stage. In this case report, we present a case of a 32-week gestational age preterm newborn with a prenatal diagnosis of intrauterine growth restriction, with a persistent left superior vena cava, interatrial communication and a horseshoe kidney. Additionally, postnatal optic nerve atrophy was diagnosed. By using exome sequencing, the pathogenic variant c.1877del; p.his626Lefus*78 was identified in the RMB10 gene. Due to a lack of reports in the medical literature, the phenotype has not fully been described. Here, we report on a patient with TARP syndrome and a previously unreported mutation, c.1877del; p.his627Leufs*78, which is predicted to generate a truncated and/or protein decay of the RBM10 transcript.

Ebstein anomaly is a congenital heart defect with a low prevalence and high mortality in the early stages of life. In medical literature, there is no reported association between Ebstein anomaly and cri du chat syndrome. Here, we report the case of a full-term newborn with a low weight for his age and who had a prenatal diagnosis of Ebstein anomaly and a postnatal diagnosis of cri du chat syndrome and 20q duplication detected on array CGH. The patient required medical treatment with inotropic support, high-frequency ventilation and nitric oxide, with an adequate response. Surgical intervention was not needed.

OBJETIVO: determinar a frequência, as complicações e a sazonalidade com que a infecção pelo vírus sincicial respiratório (VSR) do trato respiratório inferior causa hospitalização em neonatos com um ano de idade ou menos, em seis cidades da Colômbia. MÉTODOS: estudo observacional prospectivo multicêntrico de um ano que incluiu 717 pacientes, que compareceram ao serviço de emergência com sintomas respiratórios em seis cidades da Colômbia. As crianças hospitalizadas foram testadas para verificar a existência de VSR com teste de imunofluorescência das secreções nasofaríngeas. Foram realizadas análises descritivas e estatísticas da população. RESULTADOS: a população estudada incluiu 717 pacientes com uma idade média de 3,6 meses (DP 3,25), na proporção de 4:3 do sexo masculino para o sexo feminino e uma prevalência de ITRI por VSR de 30% (216 neonatos/cidade, faixa 26-49%). Os fatores de risco para ITRI por VSR foram encontrados em 8,2% da população, dos quais 28,8% foram positivos para VSR. Os grupos positivo e negativo para VSR foram comparados utilizando um teste t bicaudal com IC de 95%, p < 0,05. Não foram constatadas diferenças estatisticamente significativas. Todas as cidades apresentaram trimestres anuais específicos para ocorrência de ITRI por VSR. CONCLUSÕES: o VSR causou uma em três internações de ITRI na população, com uma incidência de 30%. Isso confirma uma circulação contínua do VSR na Colômbia, que varia pela localização geográfica.
OBJECTIVE: to determine the frequency, complications and seasonality at which respiratory syncytial virus (RSV) infection of the lower respiratory tract causes hospitalization in infants of age 1 year or less in 6 cities of Colombia. METHODS: one-year prospective multicentric observational study that included 717 patients presenting to the emergency department with respiratory symptoms in 6 cities of Colombia. Hospitalized children were tested for RSV with an immunofluorescence rapid test in nasopharyngeal secretions. Descriptive and statistical analyses of the population were conducted. RESULTS: the study population included 717 patients with a mean age of 3.6 months (SD 3.25), 4:3 male: female ratio and a positive RSV LRTI prevalence of 30.0% (216 infants/City, range 26.0 - 49.0%). Risk factors for RSV LRTI were found in 8.2% of the population, of which 28.8% were RSV positive. RSV positive and negative groups were compared using a two-tailed t test with 95.0%CI, p < 0.05. No statistically significant differences were found. All cities presented specific year trimesters in the occurrence of RSV LRTI. CONCLUSIONS: the RSV caused 1 in 3 LRTI hospitalizations in the population, with an incidence of 30.0%. This confirms a continuous circulation of RSV in Colombia varying by geographic location.

In malaria-endemic regions of Latin America, little is known about malaria in pregnancy. To characterize the clinical and laboratory findings of maternal infection, we evaluated 166 cases of pregnant women infected with Plasmodium spp. in a prospective study conducted in northwestern Colombia during 2005-2006. A total of 89.8% (149 of 166) had fever or a history of fever in the past 48 hours, 9.0% (15 of 166) had severe malaria, of which 66.7% was caused by Plasmodium vivax and 33.3% by P. falciparum. Hepatic dysfunction was the main complication (9 of 15) observed. The proportion of severe cases was similar for both species (P = 0.41). In malaria-endemic areas of Colombia, malaria in pregnancy has a broad clinical spectrum. In pregnant women, P. vivax infection frequently leads to organ-specific complications.

Approximately 170 million inhabitants of the American continent live at risk of malaria transmission. Although the continent's contribution to the global malaria burden is small, at least 1-1.2 million malaria cases are reported annually. Sixty percent of the malaria cases occur in Brazil and the other 40% are distributed in 20 other countries of Central and South America. Plasmodium vivax is the predominant species (74.2%) followed by P. falciparum (25.7%) and P. malariae (0.1%), and no less than 10 Anopheles species have been identified as primary or secondary malaria vectors. Rapid deforestation and agricultural practices are directly related to increases in Anopheles species diversity and abundance, as well as in the number of malaria cases. Additionally, climate changes profoundly affect malaria transmission and are responsible for malaria epidemics in some regions of South America. Parasite drug resistance is increasing, but due to bio-geographic barriers there is extraordinary genetic differentiation of parasites with limited dispersion. Although the clinical spectrum ranges from uncomplicated to severe malaria cases, due to the generally low to middle transmission intensity, features such as severe anemia, cerebral malaria and other complications appear to be less frequent than in other endemic regions and asymptomatic infections are a common feature. Although the National Malaria Control Programs (NMCP) of different countries differ in their control activities these are all directed to reduce morbidity and mortality by using strategies like health promotion, vector control and impregnate bed nets among others. Recently, international initiatives such as the Malaria Control Program in Andean-country Border Regions (PAMAFRO) (implemented by the Andean Organism for Health (ORAS) and sponsored by The Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM)) and The Amazon Network for the Surveillance of Antimalarial Drug Resistance (RAVREDA) (sponsored by the Pan American Health Organization/World Health Organization (PAHO/WHO) and several other partners), have made great investments for malaria control in the region. We describe here the current status of malaria in a non-Amazonian region comprising several countries of South and Central America participating in the Centro Latino Americano de Investigación en Malaria (CLAIM), an International Center of Excellence for Malaria Research (ICEMR) sponsored by the National Institutes of Health (NIH) National Institute of Allergy and Infectious Diseases (NIAID).
