Are the first 1,000 days of life a neglected vital period to prevent the impact on maternal and infant morbimortality of infectious diseases in Latin America? Proceedings of a workshop of experts from the Latin American Pediatric Infectious Diseases Society, SLIPE.

While the first 1,000 days of life are a critical period in child's development, limited information on the main determinants affecting this period in the Latin America and the Caribbean (LAC) region is available. Therefore, the Latin American Pediatric Infectious Diseases Society (SLIPE) held an ad hoc workshop in May 2022 with an expert panel designed to analyze the main factors impacting the development of childhood in the region during this period and the main causes of maternal infant morbimortality. The aim was to identify priorities, generate recommendations, and advise practical actions to improve this situation. Considerations were made about the challenges involved in bridging the gap that separates the region from more developed countries regarding an optimal early childhood and maternal care. Extensive discussion was conducted to reach consensus recommendations on general strategies intended to reduce maternal and infant mortality associated with infections and immune-preventable diseases during the first 1,000 days of life in LAC.

Factors Associated With Hospitalization or Intensive Care Admission in Children With COVID-19 in Latin America.

Background: Limited data is available from low-middle and upper-middle income countries of the factors associated with hospitalization or admission to pediatric intensive care unit (PICU) for children with COVID-19. Objective: To describe the factors associated with hospitalization or PICU admission of children with COVID-19 in Latin America. Method: Multicenter, analytical, retrospective study of children reported from 10 different Latin American countries to the Latin-American Society of Pediatric Infectious Diseases (SLIPE-COVID) research network from June 1, 2020, and February 28, 2021. Outpatient or hospitalized children <18 years of age with COVID-19 confirmed by polymerase chain reaction or antigen detection from the nasopharynx were included. Children with multisystem inflammatory syndrome in children (MIS-C) were excluded. Associations were assessed using univariate and multivariable logistic regression models. Results: A total of 1063 children with COVID-19 were included; 500 (47%) hospitalized, with 419 (84%) to the pediatric wards and 81 (16%) to the ICU. In multivariable analyses, age <1 year (Odds Ratio [OR] 1.78; 95% CI 1.08-2.94), native race (OR 5.40; 95% CI 2.13-13.69) and having a co-morbid condition (OR 5.3; 95% CI 3.10-9.15), were associated with hospitalization. Children with metabolic or endocrine disorders (OR 4.22; 95% CI 1.76-10.11), immune deficiency (1.91; 95% CI 1.05-3.49), preterm birth (OR 2.52; 95% CI 1.41-4.49), anemia at presentation (OR 2.34; 95% CI 1.28-4.27), radiological peribronchial wall thickening (OR 2.59; 95% CI 1.15-5.84) and hypoxia, altered mental status, seizures, or shock were more likely to require PICU admission. The presence of pharyngitis (OR 0.34; 95% CI 0.25-0.48); myalgia (OR 0.47; 95% CI 0.28-0.79) or diarrhea (OR 0.38; 95% CI 0.21-0.67) were inversely associated with hospital admission. Conclusions: In this data analysis reported to the SLIPE research network in Latin America, infants, social inequalities, comorbidities, anemia, bronchial wall thickening and specific clinical findings on presentation were associated with higher rates of hospitalization or PICU admission. This evidence provides data for prioritization prevention and treatment strategies for children suffering from COVID-19.

Current regional consensus recommendations on infant vaccination of the Latin American pediatric infectious diseases society (SLIPE).

INTRODUCTION: The 1st Regional Experts on Infant Vaccination (REIV) meeting generated updated consensus recommendations to improve the control of various major vaccine preventable diseases (VPD) in Latin America. AREAS COVERED: Workshops highlighted recent changes in immunization schedules within the region, experience of countries incorporating combined acellular pertussis vaccines schedules and parenteral inactivated polio vaccine (IPV). The need to definitively replace oral polio vaccine (OPV) by IPV, and potential benefits of introducing new combined vaccines, were extensively discussed. EXPERT OPINION: REIV strongly advised immediate adoption of either complete IPV schedules for all Latin America or schedules including at least two initial doses of IPV. Use of fractional doses of intradermally administered IPV (fIPV ID) was not recommended due to lower immunogenicity, lack of evidence on long-term protection, and technical difficulty to implement. Routine pertussis vaccination of pregnant women in addition to health workers of neonatology units and any previously unimmunized parent was encouraged. Administration of HBV vaccine to newborns within the first 24 hours of life, and then at 2, 4, and 6 months, and of a booster dose of conjugate Hib vaccine at age 12 through 15 months, was also recommended. Incorporation of combined vaccines (CV) was considered potentially advantageous.
