Benefits and challenges of consolidating public health functions into a National Public Health Institute: a policy analysis.

National Public Health Institutes (NPHIs) around the world vary in composition. Consolidated organizational models can bring together critical functions such as disease surveillance, emergency preparedness and response, public health research, workforce development and laboratory diagnosis within a single focal point. This can lead to enhanced coordination and management of resources and enable more efficient and effective public health operations. We explored stakeholders' perceptions about the benefits and challenges of consolidating public health functions in an NPHI in seven countries where the US Centers for Disease Control and Prevention has supported NPHI establishment and strengthening. From August 2019 through January 2020, we interviewed a total of 96 stakeholders, including NPHI staff (N = 43), non-NPHI government staff (N = 29) and non-governmental and international organization staff (N = 24) in Cambodia, Colombia, Liberia, Mozambique, Nigeria, Rwanda and Zambia. We conducted a policy analysis using Tea Collins's health policy analysis framework to assess various possible options for coordinating public health functions and their likely effectiveness. The findings can be used by policymakers as they consider public health infrastructure. We found that consolidating functions in an NPHI, to the extent politically and organizationally feasible, promotes efficiency, flexibility and coordination, as well as supports data-driven health recommendations to government decision makers. Countries pursuing NPHI establishment can weigh the potential challenges and benefits of consolidating functions when determining which public health functions will comprise the NPHI, including clarity of role, access to resources, influence over decisions and political viability.

Monkeypox virus genome sequence from an imported human case in Colombia. / Secuencia genómica del virus de la viruela símica de un caso importado en Colombia

INTRODUCTION: Monkeypox virus (MPXV) is an enveloped double-stranded DNA virus with a genome of approximately 197.209 bp. The current classification divides MPXV into three clades: Clade I (Central African or Congo Basin clade) and clades IIa and IIb (West African clades). OBJECTIVE: To report the complete genome and phylogenetic analysis of a human monkeypox case detected in Colombia. MATERIALS AND METHODS: Exudate from vesicular lesions was obtained from a male patient with recent travel history to Spain. A direct genomic approach was implemented in which total DNA from the sample was purified through a column-based method, followed by sequencing on the Nanopore GridION. Reads were aligned against the MPXV reference genome using minimap2 v.2.24 and phylogenetic inference was performed using maximum likelihood estimation. RESULTS: A total of 11.951 reads mapped directly to a reference genome with 96.8% of coverage (190.898 bp). CONCLUSION: Phylogenetic analysis of the MPXV circulating in Colombia demonstrated its close relationship to clade IIb responsible for the multi-country outbreak in 2022.

Un total de 11.951 lecturas se alinearon directamente con el genoma de referencia con una cobertura del 96,8 % (190.898 pb). Conclusión. El análisis filogenético del MPXV circulante en Colombia demostró su estrecha relación con el clado de África occidental (clado IIb) responsable del brote en múltiples países en el 2022.

Seroprevalence of SARS-CoV-2 Antibodies in Children and Adolescents: Results From a Population-Based Survey in 10 Colombian Cities.

Background. Understanding COVID-19 dynamics in Colombia during the first pandemic year (2020) gives important insights surrounding population's exposure risk and specific susceptibilities. Seroprevalence studies can aid in having a broader understanding of the disease, offering a more inclusive view of the pandemic's impact across the population. Methods. A population-based cross-sectional study to assess antibodies against SARS-CoV-2 in 10 Colombian cities was developed between September and December 2020. Cities were grouped according development typology (Robust (RD), Intermediate (ID) and Incipient (InD)). Detection of total antibodies (IgM + IgG) against SARS-CoV-2 was employed. Univariate Odds Ratios (OR) were estimated for antibody results and selected variables. Results. About 3124 children aged between 5 and 17 years were included. Factors related to lower seropositive results were affiliation to the employer-based health insurance in RD and ID cities (OR: 0.579, 95% CI 0.477-0.703, OR: 0.648, 95%CI 0.480-0.874 respectively) and living in a household with adequate access to public services only for ID cities (OR: 0.679. 95% CI 0.491-0.939). Higher seropositivity rates in RD and ID cities were seen in children belonging to the low socioeconomic stratum (RD: OR: 1.758, 95% CI 1.427-2.165; ID: OR: 2.288, 95% CI 1.599-3.275) and living in an overcrowded household (RD: OR: 1.846, 95% CI 1.467-2.323; ID: OR: 2.379, 95% CI 1.769-3.199). Conclusions. Children and adolescents showed substantial impact from the COVID-19 pandemic. Disadvantageous living conditions were found to be significantly related to having a positive SARS-CoV-2 antibody test. These results highlight the need to prioritize vulnerable populations in the context of health emergencies.

Adverse effects of modeling substances in Cali, Colombia / Efectos adversos de las sustancias modelantes en Cali, Colombia.

Introduction: The desire to improve one's physical appearance through simple and economical methods has resulted in the indiscriminate application of modeling substances. As a result, iatrogenic allogenosis has emerged as an increasingly prevalent disease in Latin America. Objective: To describe the epidemiological characteristics and adverse effects arising from the use of modeling substances in a group of patients from Cali, Colombia. Materials and methods: We conducted a retrospective review of the medical records of patients who consulted for complications arising from the use of modeling substances during a six-year period. Results: A total of 1,322 patients were included of whom 95.5% were women. Patients' ages ranged from 19 to 83 years, with an average of 39 years. The most infiltrated anatomical site showing adverse effects due to modeling substances was the buttocks. The asymmetry and increased volume of the infiltrated site were the most common signs while pain, mood disturbances, and depression or anxiety were the most commonly perceived symptoms. A total of 41.8% of patients ignored what substances they had received, and 28.5% received biopolymers; these procedures were mostly performed by non-qualified personnel. Conclusions: The care of these patients requires multidisciplinary teams to establish treatment alternatives to improve their quality of life. In addition, the regulation of establishments, as well as the surveillance, inspection, and control of the imports and use of these substances should be warranted.

A first description of the Colombian national registry for rare diseases.

OBJECTIVE: Orphan diseases must be considered a public health concern, underlying country-specific challenges for their accurate and opportune diagnosis, classification and management. Orphan disease registries have not yet been created in South America, a continent having a population of ~ 415 million inhabitants. In Colombia ~ 3 million of patients are affected by rare diseases. The aim of the present study was to establish the first Colombian national registry for rare diseases. The registry was created after the establishment of laws promoting the development of clinical guidelines for diagnosis, management, census and registry of patients suffering rare diseases. RESULTS: In total, 13,215 patients were recorded in the Colombian registry. The survey reported 653 rare diseases. The most common diseases were congenital factor VIII deficiency (hemophilia A) (8.5%), myasthenia gravis (6.4%), von Willebrand disease (5.9%), short stature due to growth hormone qualitative anomaly (4.2%), bronchopulmonary dysplasia (3.9%) and cystic fibrosis (3.2%). Although, a marked under-reporting of cases was observed, some pathologies displayed similar behavior to that reported by other initiatives and databases. The data currently available in the registry provides a baseline for improvement regarding local and regional surveys and the start for better understanding rare diseases in Colombia.
