Variação na detecção da síndrome congênita do Zika em função de alterações em protocolos
In 2015, Brazil faced a Zika virus epidemic that spread to other countries in the world. As a result, recommendations regarding reporting criteria for congenital Zika syndrome (CZS) were issued in the form of protocols. The frequent changes in these recommendations may have affected clinical management and the access to post-diagnostic support by children who were affected by CZS, but who ended up not being identified. In the present study, 39 ca…

Progress and challenges in implementing HIV care and treatment policies in Latin America following the treatment 2.0 initiative
A relatively good level of progress was perceived in the recommendations related to optimization of ART regimens. Challenges remain on the improvement of recommendations related to health system strengthening and the promotion and support aimed at community-based organizations as part of the response to HIV/AIDS in Latin America.

Determinantes de la cuenta corriente en Colombia
Este trabajo pretende examinar los determinantes de la cuenta corriente en Colombia entre 1950 y 1997 a partir del enfoque intertemporal. Este plantea, en su forma más simple, que las desviaciones transitorias del ingreso, del consumo privado y del consumo público, afectan positivamente, en el primer caso, y negativamente, en el segundo y tercero a la cuenta corriente. Esto es, los agentes económicos financian las caídas transitorias del producto…

Participation of traditional birth attendants in prevention of mother-to-child transmission of HIV services in two rural districts in Zimbabwe
Although the long-term goal of ANC service delivery in Zimbabwe remains the provision of skilled delivery attendance, PMTCT programmes will benefit from complementary approaches to prevent missed opportunities. TBAs are willing to expand their scope of work regarding activities related to PMTCT. There is a need to reinforce their knowledge on MTCT prevention measures and better integrate them into the health system
