2. Transcatheter aortic valve implantation versus surgical aortic valve replacement for treatment of severe aortic stenosis: comparison of results from randomized controlled trials and real-world data
Abstract Objective: Results from randomized controlled trials (RCTs) and real-world study (RWS) appear to be discordant. We aimed to investigate whether data derived from RCTs and RWS evaluating long-term all-cause mortality of transcatheter aortic valve implantation (TAVI) versus surgical aortic valve replacement (SAVR) in patients with severe aortic steno

5. Decentralising HIV treatment in lower- and middle-income countries
BACKGROUND: Policy makers, health staff and communities recognise that health services in lower- and middle-income countries need to improve people's access to HIV treatment and retention to treatment programmes. One strategy is to move antiretroviral delivery from hospitals to more peripheral health facilities or even beyond health facilities. This could in

6. Association between self-rated oral appearance and the need for dental prostheses among elderly Brazilians
We investigated the association between poor self-rated oral appearance and the need for dental prostheses among elderly Brazilians. National data from an epidemiological survey on oral health in Brazil conducted from 2002 to 2003 by the Ministry of Health (SB, Brazil) with a multistage random sample of 4,839 individuals aged 65–74 years in 250 towns were

7. Experimental evaluation in dogs of importance of bowel preparation on colo-colonic anastomosis. / AvaliaÃÃo da anastomose colo-cÃlica com e sem preparo intestinal. Estudo experimental em cÃes
The objective of this study was to evaluate the efficacy of colo-colonic anastomosis in dogs with and without preoperative bowel preparation. The experiment included 42 healthy female mongrel dogs (Canis familiaris) weighing 8.4-16.9 Kg, supplied by the municipal dog pound of Teresina, PiauÃ. The animals were distributed at random in two groups of 21 animal

8. Algoritmo de escalonamento DRR com quantum adaptativo para o tráfego downlink de redes IEEE 802.16j / DRR adaptive quantum scheduling algorithm for downlink traffic of IEEE 802.16j networks
IEEE 802.16j networks provide, through the Relay Station (RS), improvements with regard to previous specifications of WiMAX in terms of increased coverage area, reduction of deployment costs due to low cost of RS compared to a Base Station (BS) and system average throughput increase. Its main purpose is to meet demands for wireless broadband access at lower

9. Modeling and simulation of device variability and reliability at the electrical level
In nanometer scale complementary metal-oxide-semiconductor (CMOS) parameter variations pose a challenge for the design of high yield integrated circuits. This work presents models that were developed to represent physical variations affecting Deep- Submicron (DSM) transistors and computationally efficient methodologies for simulating these devices using Elec

10. Extracting samples of high diversity from thematic collections of large gene banks using a genetic-distance based approach.
Background Breeding programs are usually reluctant to evaluate and use germplasm accessions other than the elite materials belonging to their advanced populations. The concept of core collections has been proposed to facilitate the access of potential users to samples of small sizes, representative of the genetic variability contained within the gene pool of

11. Centros viva vida de referência secundária: um estudo de caso da atenção pediátrica
Public policies related to child health and reducing infant mortality are not new in Brazil. Despite all the progress, the infant mortality rate is still at levels considered unacceptable, requiring the formulation of consistent public policies to confront this situation. The current strategy of Minas Gerais to reduce this indicator is the Programa Viva Vida

12. Controle de acesso baseado em biometria facial
Face recognition is one of the most ordinary and natural task carried out by humans. Even though it is a simple task, it has proved to be a major challenge for artificial intelligence and computer vision researchers. Researches on object detection and recognition, and more specifically those related to human face, has greatly increased their demand in recent
