[Regulation and performance of health systems: a review of analytic frameworksRegulamentação e desempenho dos sistemas de saúde: revisão das estruturas analíticas].

The private health sector has expanded significantly in recent decades, both in Latin America and other regions. Governments and international organizations have dealt with this process in a heterogeneous manner. A policy approach and, above all, a regulatory framework, are required in order to put health objectives and the right to health above the profit motive that drives private sector participation.

Acquired : Current Concepts - "From Adult Acquired to Progressive Collapsing Foot Deformity".

The clinical disorder traditionally known as or has been the subject of several publications over the past two decades. Now, it is understood that the problem does not lie in the posterior tibial tendon per se and may even occur without tendon injury. Studies have brought new concepts and understanding that question the views on this subject, culminating in the replacement of existing classifications with one that is more assertive and discriminative of the potential presentation patterns of the deformity.

An epizootic of highly pathogenic avian influenza virus H7N3 in a Mexican ecological reserve.

In this case study, we describe an outbreak of highly pathogenic avian influenza (HPAI) virus subtype H7N3 in an ecological reserve in Chiapas, Mexico, affecting captive and wild birds. The virus was detected mainly in plain chachalacas displaying respiratory and gastrointestinal clinical signs and death within 24 hours. Mortality in white-fronted parrots and a clay-colored thrush was also recorded.

Vesicular Stomatitis Virus Transmission Dynamics Within Its Endemic Range in Chiapas, Mexico.

Vesicular stomatitis virus (VSV), comprising vesicular stomatitis New Jersey virus (VSNJV) and vesicular stomatitis Indiana virus (VSIV), emerges from its focus of endemic transmission in Southern Mexico to cause sporadic livestock epizootics in the Western United States. A dearth of information on the role of potential arthropod vectors in the endemic region hampers efforts to identify factors that enable endemicity and predict outbreaks. In a two-year, longitudinal study at five cattle ranches in Chiapas, Mexico, insect taxa implicated as VSV vectors (blackflies, sandflies, biting midges, and mosquitoes) were collected and screened for VSV RNA, livestock vesicular stomatitis (VS) cases were monitored, and serum samples were screened for neutralizing antibodies.

[Strengthening doctoral programs in nursing based on health care needsFortalecimento dos programas de doutorado em enfermagem com base nas necessidades de saúde].

This article aims to analyze and contextualize the training of nurses at the postgraduate level, and to present strategic orientations to expand their doctoral education in Latin America and the Caribbean. This paper presents strategies to advance the potential of nurses' contribution to health systems and the development of scientific competencies through postgraduate studies-at the doctoral level-with emphasis on cooperation and internationalization, training aligned with the health needs of the population, transfer of knowledge to practice and sustainability of actions. Nurses are well positioned to act as researchers, faculty members and leaders, and to contribute to the development of more effective strategies for future actions and policies that are required by health systems.

XIII Consenso SIBEN sobre Traslado Neonatal: Establecer protocolos estructurados para el proceso del traslado neonatal podría mejorar los desenlaces.

La centralización de los partos de alto riesgo en los hospitales con el más alto nivel de atención es fundamental para ampliar el margen de seguridad materno-neonatal y mejorar los desenlaces. Por lo tanto, es altamente recomendable trasladar oportunamente a las pacientes gestantes portadoras de embarazos de alto riesgo y/o con amenazas de parto pretérmino a centros de atención terciaria, sin embargo, no siempre es posible anticipar los riesgos antenatalmente, lo cual resulta en la necesidad de trasladar a neonatos en estado crítico. Lamentablemente, la movilización de los recién nacidos compromete aún más su estado de salud, especialmente en los países latinoamericanos.

[Intentional search and reclassification of maternal deaths: quality information and its analysis to reduce maternal mortalityBusca intencional e reclassificação de mortes maternas: informação de qualidade e sua análise para reduzir a mortalidade materna].

Objective: To describe the methodology of the intentional search and reclassification of maternal deaths (BIRMM, acronym in Spanish), which allows the identification and correction of misclassification and underreporting of maternal deaths.

Methods: The BIRMM methodology, initially developed in Mexico in 2003 and disseminated in other Latin American countries since 2012, was used. BIRMM consists of four key components: i) reclassification of confirmed maternal deaths; ii) identification and investigation of suspected cases of maternal death; iii) cross-referencing with other information sources; and iv) publication of results and statistical analysis.
