RESUMO

During the 2022 monkeypox (mpox) epidemic's first 100 days, 99 non-endemic countries, including 25 Latin American and Caribbean (LAC) countries, reported >64,000 cases. We aim to assess the cases' introduction, epidemiological profile, initial response, transmission dynamics, and main challenges ahead among LAC countries during the first 100 days of the mpox 2022 epidemic. We used mixed methods, including desktop research and open data analysis. The 2022 mpox epidemic has progressed consistently through LAC, with Brazil and Peru combining for over 80% of the confirmed LAC cases. Although Brazil reports the highest mpox case counts (n = 4472), Peru reports the highest incidence (41 confirmed cases per 1 million inhabitants). Initially, LAC missed the opportunity to focus on the high-risk population, including the people living with HIV (PLHIV) and gay, bisexual, and men who have sex with men (GBMSM). Moreover, the main challenges ahead include stigmatization, vaccine inequity, barriers to accessing diagnostics, and complete isolation. Furthermore, we estimated that Colombia, Brazil, the United States, and Peru are the world frontrunners in mpox duplication time (estimated between 6.4 and 8.8) and effective reproductive number (estimated between 2.7 and 3.8). In addition, Brazil reported its first case of inverse zoonosis in a dog and Peru its first autochthonous MPXV lineage, B.1.6. LAC has become the epicenter of the 2022 mpox epidemic, with Brazil and Peru emerging as the new mpox hot zones. Therefore, LAC countries must join efforts to control this epidemic and overcome the challenges of vaccine inequity and stigmatization.

RESUMO

Coronavirus disease 19 (COVID-19) is a pandemic caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). It is suggested that life at high altitude may reduce COVID-19 infections and case-fatality rates (cases/deaths). We study data from Peru COVID-19 pandemics, which first case was recorded on March 6th, 2020. By June 13, 2020 there were 6498 deaths, and 224,132 SARS-CoV-2 positives. Using data from 185 capitals of provinces with altitudes ranging from 3 to 4342 m, we confirm previous reports that infection with COVID-19 at high altitude is reduced. However, case-fatality rate is not dependent of altitude. We have also presented first evidence that female protection towards death by COVID-19 is reduced as altitude of residence increases.

RESUMO

Objective To report the results of a needs assessment of research and training in Medical Informatics (MI) and Bioinformatics (BI) in Latin America. Methods and results This assessment was conducted by QUIPU: The Andean Global Health Informatics Research and Training Center. After sending email invitations to MI-BI related professionals from Latin America, 142 surveys were received from 11 Latin American countries. The following were the top four ranked MI-related courses that a training programme should include: introduction to biomedical informatics; data representation and databases; mobile health; and courses that address issues of security, confidentiality and privacy. Several new courses and topics for research were suggested by survey participants. The information collected is guiding the development of curricula and a research agenda for the MI and BI QUIPU multidisciplinary programme for the Andean Region and Latin America.

RESUMO

The public sectors of developing countries require strengthened capacity in health informatics. In Peru, where formal university graduate degrees in biomedical and health informatics were lacking until recently, the AMAUTA Global Informatics Research and Training Program has provided research and training for health professionals in the region since 1999. The Fogarty International Center supports the program as a collaborative partnership between Universidad Peruana Cayetano Heredia in Peru and the University of Washington in the United States of America. The program aims to train core professionals in health informatics and to strengthen the health information resource capabilities and accessibility in Peru. The program has achieved considerable success in the development and institutionalization of informatics research and training programs in Peru. Projects supported by this program are leading to the development of sustainable training opportunities for informatics and eight of ten Peruvian fellows trained at the University of Washington are now developing informatics programs and an information infrastructure in Peru. In 2007, Universidad Peruana Cayetano Heredia started offering the first graduate diploma program in biomedical informatics in Peru.

RESUMO

BACKGROUND: Low-cost handheld computers (PDA) potentially represent an efficient tool for collecting sensitive data in surveys. The goal of this study is to evaluate the quality of sexual behavior data collected with handheld computers in comparison with paper-based questionnaires. METHODS: A PDA-based program for data collection was developed using Open-Source tools. In two cross-sectional studies, we compared data concerning sexual behavior collected with paper forms to data collected with PDA-based forms in Ancon (Lima). RESULTS: The first study enrolled 200 participants (18-29 years). General agreement between data collected with paper format and handheld computers was 86%. Categorical variables agreement was between 70.5% and 98.5% (Kappa: 0.43-0.86) while numeric variables agreement was between 57.1% and 79.8% (Spearman: 0.76-0.95). Agreement and correlation were higher in those who had completed at least high school than those with less education. The second study enrolled 198 participants. Rates of responses to sensitive questions were similar between both kinds of questionnaires. However, the number of inconsistencies (p = 0.0001) and missing values (p = 0.001) were significantly higher in paper questionnaires. CONCLUSION: This study showed the value of the use of handheld computers for collecting sensitive data, since a high level of agreement between paper and PDA responses was reached. In addition, a lower number of inconsistencies and missing values were found with the PDA-based system. This study has demonstrated that it is feasible to develop a low-cost application for handheld computers, and that PDAs are feasible alternatives for collecting field data in a developing country.

RESUMO

The geometry proposition that "four points not in a plane describe one and only one sphere" provides a novel tool for analyzing protein-induced distortions in [4Fe-4S] clusters. A geometrically perfect reference structure comprises interlaced, regular tetrahedra of Fe, S, and S gamma atoms having T(d) symmetry. Three circumspheres are defined by the three sets of four atoms, the circumcenters of which are unique points within the cluster. The structure is thus re-defined by the positions of the circumcenters in xyz space and the r, theta, phi of each atom on its respective sphere. Analysis of 12 high-resolution structures of protein-bound and small molecule [4Fe-4S](SR)(4) clusters revealed: (a) the circumcenters are generally non-coincident by approximately 0.01 to approximately 0.06 A; (b) the Fe radius, r(Fe), is nominally independent of core oxidation state, having values between 1.66 to 1.69 A, whereas r(S) and r(SG), which have ranges of 2.18-2.24 A and 3.87-3.94 A, respectively, both increase by as much as approximately 3% upon reduction from the 3+ to the 1+ core valence; (c) deviation of some atoms from the theta, phi of a perfect tetrahedron can be large, approximately 10 degrees, and sets of atoms can show patterns of motion on their spheres that result from changes in Fe-S bond lengths. Density functional theory calculations suggest that the [4Fe-4S] core itself requires rather little energy to distort (approximately 2 kcal/mol), whereas significantly more energy is required to distort the Sgamma shell (~4 kcal/mol) to that of cluster I in Clostridium acidurici ferredoxin.

RESUMO

The Metalloprotein Database and Browser (MDB; http://metallo.scripps.edu) at The Scripps Research Institute is a web-accessible resource for metalloprotein research. It offers the scientific community quantitative information on geometrical parameters of metal-binding sites in protein structures available from the Protein Data Bank (PDB). The MDB also offers analytical tools for the examination of trends or patterns in the indexed metal-binding sites. A user can perform interactive searches, metal-site structure visualization (via a Java applet), and analysis of the quantitative data by accessing the MDB through a web browser without requiring an external application or platform-dependent plugin. The MDB also has a non-interactive interface with which other web sites and network-aware applications can seamlessly incorporate data or statistical analysis results from metal-binding sites. The information contained in the MDB is periodically updated with automated algorithms that find and index metal sites from new protein structures released by the PDB.
