Policies and processes for human papillomavirus vaccination in Latin America and the Caribbean

e124Objectives. Three highly effective vaccines are available to prevent human papillomavirus (HPV) infection, and they have been introduced in many countries around the world. This article describes advances and challenges in introducing HPV vaccines in the Expanded Program of Immunization (EPI) of countries in Latin America and the Caribbean (LAC). Methods. We reviewed national and regional sources of information to identify LAC countries with and without universal HPV vaccination, along with the year of introduction, type of HPV vaccine, vaccination scheme, age groups targeted, and coverage level reached. Incidence rates of cervical cancer were compared across countries with and without an HPV vaccination program, in order to identify inequities in access to HPV vaccines. Results. So far, 10 LAC countries have supplied data on their vaccination policies and vaccination coverage rates to the Pan America Health Organization. The majority of those 10 started their vaccination programs using quadrivalent vaccine. Only Chile, Ecuador, and Mexico started their programs using a two-dose scheme. However, by the end of 2016, most of the other countries had switched from a three-dose to a two-dose scheme. Different age groups are targeted in the various programs. Some countries vaccinate one-year birth cohorts, while others vaccinate multiple-year birth cohorts. By the end of 2014, coverage with at least two doses ranged from a low of 2% to a high of 86%. With the exception of Venezuela, the LAC countries with the largest populations introduced universal HPV vaccination between 2010 and 2014. Despite the progress that has occurred in some LAC countries, there are still 10 LAC nations with cervical cancer rates above the LAC average (21.2 cases per 100 000) that have not introduced an HPV vaccine in their EPI. Conclusions. With several key adjustments, HPV vaccination programs across Latin America and the Caribbean could be substantially strengthened. Ongoing monitoring of HPV infection outcomes is needed in order to assess the impact of different vaccination policies

Reporte de Pecari tajacu y Procyon lotor con anomalías cromáticas en el Estado de Guerrero, México

Este trabajo documenta el primer registro de anomalías cromáticas en el pecarí de collar (Pecari tajacu) y el tercero en el mapache (Procyon lotor) para México. Los hallazgos se realizaron durante el monitoreo realizado entre el 2009 y el 2021, utilizando cámaras-trampa, principalmente en la ecorregión de la Sierra Madre del Sur del estado de Guerrero, México. Procyon lotor fue registrado entre el 5 de noviembre y el 1 de diciembre de 2019, en vegetación riparia de bosque tropical caducifolio (17°47’35”N, 98°39’59”W, 1134 m de altitud). Mientras que Pecari tajacu se registró el 7 de junio y el 22 de julio del 2021 en una brecha saca cosecha abandonada (17°38’12”N, 100°40’50”W; 1532 m de altitud)

Expansion of seasonal influenza vaccination in the Americas

<p>Abstract</p> <p>Background</p> <p>Seasonal influenza is a viral disease whose annual epidemics are estimated to cause three to five million cases of severe illness and 250,000 to 500,000 deaths worldwide. Vaccination is the main strategy for primary prevention.</p> <p>Methods</p> <p>To assess the status of influenza vaccination in the Americas, influenza vaccination data reported to the Pan American Health Organization (PAHO) through 2008 were analyzed.</p> <p>Results</p> <p>Thirty-five countries and territories administered influenza vaccine in their public health sector, compared to 13 countries in 2004. Targeted risk groups varied. Sixteen countries reported coverage among older adults, ranging from 21% to 100%; coverage data were not available for most countries and targeted populations. Some tropical countries used the Northern Hemisphere vaccine formulation and others used the Southern Hemisphere vaccine formulation. In 2008, approximately 166.3 million doses of seasonal influenza vaccine were purchased in the Americas; 30 of 35 countries procured their vaccine through PAHO's Revolving Fund.</p> <p>Conclusion</p> <p>Since 2004 there has been rapid uptake of seasonal influenza vaccine in the Americas. Challenges to fully implement influenza vaccination remain, including difficulties measuring coverage rates, variable vaccine uptake, and limited surveillance and effectiveness data to guide decisions regarding vaccine formulation and timing, especially in tropical countries.</p

Genetic variability and structure of jaguar (Panthera onca) in Mexican zoos

ArtículoGenealogical records of animals (studbook) are created to avoid reproduction between closely related individuals, which could cause inbreeding, particularly for such endangered species as the Panthera onca (Linnaeus, 1758). Jaguar is the largest felid in the Americas and is considered an important ecological key species. In Mexico, wild jaguar populations have been significantly reduced in recent decades, and population decline typically accompany decreases in genetic variation. There is no current census of captive jaguars in Mexico, and zoos do not follow a standardized protocol in breeding programs based on genetic studies. Here, we emphasise the importance of maintaining an adequate level of genetic variation and propose the implementation of standardised studbooks for jaguars in Mexico, mainly to avoid inbreeding. In addition, achieving the aims of studbook registration would provide a population genetic characterisation that could serve as a basis for ex situ conservation programmes

Impact of mediterranean diet promotion on environmental sustainability: a longitudinal analysis

[EN]This article aims to estimate the differences in environmental impact (greenhouse gas [GHG] emissions, land use, energy used, acidification and potential eutrophication) after one year of promoting a Mediterranean diet (MD). Methods Baseline and 1-year follow-up data from 5800 participants in the PREDIMED-Plus study were used. Each participant's food intake was estimated using validated semi-quantitative food frequency questionnaires, and the adherence to MD using the Dietary Score. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The influence of diet on environmental impact was assessed through the EAT-Lancet Commission tables. The association between MD adherence and its environmental impact was calculated using adjusted multivariate linear regression models.SIPublicación en abierto financiada por el Consorcio de Bibliotecas Universitarias de Castilla y León (BUCLE), con cargo al Programa Operativo 2014ES16RFOP009 FEDER 2014-2020 DE CASTILLA Y LEÓN, Actuación:20007-CL - Apoyo Consorcio BUCL

HPV vaccine implementation and monitoring in Latin America

Objective. To describe HPV vaccine program implementa­tion, monitoring and evaluation experiences in Latin America. Materials and methods. We reviewed published articles in peer-reviewed journals and reports from government web­sites, as well as the PAHO/WHO/UNICEF Joint Reporting form and the ICO/IARC HPV Information Centre database. Results. By December 2016, 13 countries/territories in Latin America (56%) have introduced HPV vaccines. The majority have done so in the past three years, targeting 10- 12 year old girls with a two dose schedule, through school programs. Vaccine coverage ranges from 30 to 87%. Safety monitoring is well established, but monitoring vaccine impact is not, and data are not available. Conclusions. Although Latin America is the most advanced developing region with HPV vaccine introduction, systems for its monitoring are weak and there is a paucity of consistently available coverage data for this vaccine. Challenges remain to introduce HPV vaccines in several countries, to achieve high coverage, and to strengthen monitoring, evaluation and reporting
