RESUMO
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.
RESUMO
The Global Health Consortium at Florida International University developed an end-to-end solution framework based on the input of a diverse panel of experts from middle-income country (MIC) government agencies, public health think tanks, academia, and nonprofit organizations to identify mechanisms to help MIC governments and stakeholders increase access to novel vaccines for infectious diseases. The resultant layout can be deployed to improve vaccine discovery and development, strengthen regulatory processes, and boost vaccine production, access, and implementation. Mechanisms include policies and incentives MIC governments can use to stimulate vaccine investment and activity, as well as actions government agencies can take together with other stakeholders to coordinate efforts or build capabilities. Through a series of individual virtual interviews, we engaged diverse experts from MIC government agencies, public health think tanks, academia, and nonprofit organizations who understand the vaccine ecosystem, immunization policies, and population health financing at global, regional, and country levels. Responses were mapped, and in-depth questions were prepared for a group virtual discussion. This paper is the result of such a group discussion. The panel identified clear opportunities for MICs to improve locally-driven innovations and future access to novel vaccines. It proposes a solution framework for countries considering investing in vaccine research and development and innovation to use as a guide to evaluate the steps they could take to improve such an environment and incentivize innovation in vaccine development. It is hoped that this end-to-end solution framework will become a key resource to help MICs strengthen policies and take more actions to make such improvements.

Chagas disease, also known as American trypanosomiasis, is caused by Trypanosoma cruzi, a parasite transmitted by hematophagous triatomine insects (subfamily Triatominae) belonging to the Reduviidae family, order Hemiptera. Infection occurs through contact with the feces of the infected vector at the site of its bite or on intact mucosa. [Pediatr Ann. 2023;52(10):e394-e397.].

Three Colombian patients with chronic HTLV-1 infection and severe intermediate and/or posterior uveitis are described. In one case, retinal ablation was necessary due to extensive peripheral degeneration, while the other two were successfully managed with local anti-inflammatory therapy. Gradual resolution of ocular findings was observed in all three patients on follow-up. Uveitis is a rarely recognized late complication of this infection, which represents a diagnostic and therapeutic challenge for clinicians in endemic countries. The real extension of HTLV-1 prevalence in Colombia and the frequency of its ophthalmologic complications remain to be determined.
RESUMO
BACKGROUND: Malaria-endemic areas are not spared from the impact of coronavirus disease 2019 (COVID-19), leading to co-infection scenarios where overlapping symptoms impose serious diagnostic challenges. Current knowledge on Plasmodium spp. and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) co-infection in pregnant women remains limited, especially in Latin America, where Plasmodium vivax infection is highly prevalent. METHODS: This is a case series of five pregnant women with P. vivax and SARS-CoV-2 co-infection hospitalized in two main malaria referral centers of the Capital District and Bolivar state, Venezuela between March 13, 2020 and December 31, 2021. RESULTS: Clinical and laboratory data from five pregnant women with a mean age of 22 years were analyzed; three of them were in the third trimester of pregnancy. Comorbidities included obesity in two cases, hypertension in one, and asthma in one. Three out of five patients had severe to critical COVID-19 disease. Dry cough, fever, chills, and headache were the most frequent symptoms reported. Laboratory analyses showed elevated aspartate/alanine aminotransferase and creatinine levels, thrombocytopenia, and severe anemia as the most relevant abnormalities. The mean period between symptom onset and a positive molecular test for SARS-CoV-2 infection or positive microscopy for Plasmodium spp. was 4.8 ± 2.5 days and 2.8 ± 1.6 days, respectively. The mean hospital stay was 5.4 ± 7 days. Three women recovered and were discharged from the hospital. Two women died, one from cerebral malaria and one from respiratory failure. Three adverse fetal outcomes were registered, two miscarriages and one stillbirth. CONCLUSION: This study documented a predominance of severe/critical COVID-19 disease and a high proportion of adverse maternal-fetal outcomes among pregnant women with malaria and COVID-19 co-infection. More comprehensive prospective cohort studies are warranted to explore the risk factors, management challenges, and clinical outcomes of pregnant women with this co-infection.

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.

INTRODUCTION: Dengue Fever is a neglected increasing public health thread. Developing countries are facing surveillance system problems like delay and data loss. Lately, the access and the availability of health-related information on the internet have changed what people seek on the web. In 2004 Google developed Google Dengue Trends (GDT) based on the number of search terms related with the disease in a determined time and place. The goal of this review is to evaluate the accuracy of GDT in comparison with traditional surveillance systems in Venezuela. METHODS: Weekly epidemic data from GDT, Official Reported Cases (ORC) and Expected Cases (EC) according the Ministry of Health (MH) was obtained Monthly and yearly correlation between GDT and ORC from 2004 until 2014 was obtained. Linear regressions taking the reported cases as dependent variable were calculated. RESULTS: The overall Pearson correlation between GDT and ORC was r=0.87 (p <0.001), while between ORC and EC according the Ministry of Health (MH) was r=0.33 (p<0.001). After clustering data in epidemic and non-epidemic weeks in comparison with GDT correlation were r=0.86 (p<0.001) and r=0.65 (p <0.001) respectively. Important interannual variation of the epidemic was observed. The model shows a high accuracy in comparison with the EC, particularly when the incidence of the disease is higher. CONCLUSIONS: This early warning tool can be used as an indicator for other communicable diseases in order to apply effective and timely public health measures especially in the setting of weak surveillance systems.

BACKGROUND: During the years 2014 and 2015, the Region of the Americas underwent a devastating epidemic of chikungunya virus (CHIKV) of the Asian genotype, resulting in millions of affected individuals. However, epidemiological and clinical information on this experience is scarce. Prior knowledge of congenital and neonatal illness caused by CHIKV is limited and almost exclusively based on data obtained from a single outbreak of the East/Central/South African (ECSA) genotype. The effect of chikungunya fever (CHIKF) on pregnancy outcomes and its consequences for infants born to infected mothers at the peak of the epidemic wave in Latin America are reviewed herein. Epidemiological and clinical data on maternal and neonatal infections were collected prospectively and analyzed. METHODS: One hundred sixty-nine symptomatic newborns with CHIKF seen at four large regional maternity hospitals in three different Central and South American countries were evaluated prospectively. The outcomes of pregnancies in symptomatic infected mothers at two of these clinical centers were also analyzed. RESULTS: The observed vertical transmission rate ranged between 27.7% and 48.29%. The incidence of congenital disease was unrelated to the use of cesarean section or natural delivery. The case fatality rate (CFR) at the only center that reported deaths was 5.3%. The most common clinical manifestations included fever, irritability, rash, hyperalgesia syndrome, diffuse limb edema, meningoencephalitis, and bullous dermatitis. Severe complications included meningoencephalitis, myocarditis, seizures, and acute respiratory failure. Leukocytosis with neutrophilia and normal or increased platelets was a common finding, and in those with signs of meningeal involvement, moderate lymphocytic pleocytosis with normal glucose and protein levels was typical. CONCLUSIONS: This study presents the largest number of symptomatic neonates with CHIKF analyzed so far in any region and is the first involving infection with the Asian genotype of CHIKV. Although the clinical manifestations found were similar to those reported previously, the percentage of neurological complications was lower. The CFR was comparatively high. Chikungunya represented a substantial risk for neonates born to symptomatic parturients during the chikungunya outbreak in the Americas Region, with important clinical and public health implications.

Two brothers with congenitally-acquired Chagas' disease (CD) diagnosed during adulthood are reported. The patients were born in the USA to a mother from Bolivia who on subsequent assessment was found to be serologically positive for Trypanosoma cruzi. Serologic screening of all pregnant women who migrated from countries with endemic CD is strongly recommended.
RESUMO
Three adult Venezuelan patients with virologically confirmed Chikungunya fever, who developed extensive acute nasal skin necrosis early in the course of a life-threatening illness characterized by shock and multiple organ dysfunction syndrome, are discussed. One patient survived and fully recovered. Nasal necrosis has not previously been associated with the disease.

Dengue is a mosquito-borne viral disease that has evolved from a sporadic infection to a major public health problem in the Americas, Southeast Asia and the western Pacific, and Africa. Its incidence has increased 30-fold over the past 50 years, and although the true disease burden is not well known, the annual incidence in some areas of the Americas may reach 5%-10% of all children when underreporting is considered. We recently analyzed the disease burden of dengue in Venezuela, and we found an overall decline in case numbers and mortality over the period of 1950-2011. However, there were increases in case number and mortality during epidemic years, especially among children. In this report, we focus on the most recent period of data, from 2000 to 2011, comparing pediatric and adult case numbers and mortality.
