1. Efficacy, Safety, and Performance of Isolated Left vs. Right Ventricular Pacing in Patients with Bradyarrhythmias: A Randomized Controlled Trial
Resumo Fundamento: Considerando-se os potenciais efeitos deletérios da estimulação do ventrículo direito (VD), a hipótese desse estudo é que a estimulação unifocal ventricular esquerda pelo seio coronário é segura e pode proporcionar melhores benefícios clínicos e ecocardiográficos aos pacientes com bradiarritmias que apresentam função ventr

2. Caloric test and video head impulse test sensitivity as vestibular impairment predictors before cochlear implant surgery
OBJECTIVES: Currently, cochlear implant procedures are becoming increasingly broad and have greatly expanded. Bilateral cochlear implants and cochlear implants are more frequently applied in children. Our hypothesis is that the video head impulse test may be more sensitive than the caloric test in detecting abnormal vestibular function before cochlear impla

4. Quality of life and mastication in denture wearers and cleft lip and palate adults
Abstract The impact of oral rehabilitation on masticatory function and oral health-related quality of life (OHRQoL) may vary with the experience of the individual with tissue loss. Our hypothesis is that patient-centered outcomes vary among adults who have experienced large defects in the maxilla due to congenital or acquired conditions even after oral rehab

5. ON HYPOTHESIS TESTS FOR COVARIANCE MATRICES UNDER MULTIVARIATE NORMALITY
In this paper we proposed a new statistical test for testing the covariance matrix in one population under multivariate normal assumption. In general, the proposed and the likelihood-ratio tests resulted in larger values of estimated powers than VMAX for bivariate and trivariate cases. VMAX was not sensitive to general changes in the covariance (correlation)

6. Pain measurement as part of primary healthcare of adult patients with sickle cell disease
OBJECTIVE: The aim of this exploratory, cross-sectional study was to evaluate pain in sickle cell disease patients and aspects related to primary healthcare. METHODS: Data were obtained through home interviews. The assessment instruments (body diagram, Numerical Pain Scale, McGill Pain Questionnaire) collected information on the underlying disease and on

7. Increased IgE serum levels are unrelated to allergic and parasitic diseases in patients with juvenile systemic lupus erythematosus
OBJECTIVE: The aim of this study was to assess the IgE serum levels in juvenile systemic lupus erythematosus patients and to evaluate possible associations with clinical and laboratory features, disease activity and tissue damage. METHODS: The IgE serum concentrations in 69 consecutive juvenile systemic lupus erythematosus patients were determined by nephelo

8. 56-month clinical performance of Class I and II resin composite restorations
OBJECTIVE: This study evaluated the 56-month clinical performance of Class I and II resin composite restorations. Filtek P60 was compared with Filtek Z250, which are both indicated for posterior restorations but differ in terms of handling characteristics. The null hypothesis tested was that there is no difference in the clinical performance of the two resin

9. Teste de validação da hipótese de Fisher : uma análise por VECM para 40 países
Neste estudo foram analisados 40 países para o período mais longo disponível no IFS, através do teste de cointegração de Johansen (1995) e Vetores de Correção de Erro (VEC) para explorar as evidências sobre a capacidade de hedge dos ativos acionários com relação à inflação. Além disso, incluiu-se um teste de cointegração com quebra estrutur

10. Bio socio economic evaluation of artisanal fisheries of Barra Bonita reservoir (SP) / Avaliação biossocioeconômica das pescarias artesanais da represa de Barra Bonita (SP)
The artisanal or small scale fisheries are practiced in small reservoirs, with an operation area restricted and familiar labor. It´s common in inland waters and the fish caught is an important source of protein for people who depend on them and provide economic returns to the fisher, despite the presence of intermediaries in the marketing of fish. The Barra

11. Estudo aleatório e controlado para testar o efeito profilático da S(+)cetamina por via peridural na dor pós-operatória de pacientes pediátricos / Randomised controlled trial to test the prophylactic effect of S(+)ketamine on pediatric postoperative pain
INTRODUCTION: Ketamine by neuroaxial as well as intravenousroute could improve postoperative analgesia. The hypothesis to be tested here was that the prophylactic epidural use the S(+) ketamine, added to a local anesthetic solution, would improve postoperative pain control after orthopedic surgical procedures in pediatric patients, when compared to intraveno
