  2. Analysis of the Cochrane Review: Pedicle Screw Fixation for Traumatic Fractures of the Thoracic and Lumbar Spine. Cochrane Database Syst Rev. 2013;05:CD009073

    Linhares, D; Neves, N; Ribeiro da Silva, M; Almeida Fonseca, J
    Traumatic fractures of the thoracic and lumbar spine are common causes of spine surgery. Pedicle screw fixation is usually chosen, using monosegmentar, short or long segment instrumentations, with or without bone graft. This review aims to evaluate the effect of transpedicular fixation in traumatic fractures of the thoracic and lumbar spine. A systematic search on controlled, randomized or quasi-randomized trials comparing different methods of surgical treatment of this fractures was performed, followed by a process of article selection, data extraction and bias assessment by 3 independent authors. Eight articles were included in a total of 5 comparisons, between different transpedicular...

  3. Percutaneous Endovascular Aortic Repair with Local Anesthesia - One Day Surgery

    Sousa, J; Brandão, D; Barreto, P; Ferreira, J; Almeida Lopes, J; Mansilha, A
    To evaluate the results of the abdominal aortic aneurism endovascular treatment (EVAR), percutaneously and with local anesthesia, according to the concept of one day surgery. MATERIAL AND METHODS: Unicentric, retrospective analysis of patients with aorto-iliac aneurysmal disease, consecutively treated by EVAR with percutaneous access trough the Preclose technique (pEVAR), according to the outpatient criteria, with one overnight stay in the hospital. The technical success, exclusion of the aneurysmal sac, endoleak, re-intervention and mortality were evaluated. RESULTS: Twenty consecutive patients (all male; mean age 74.65 years) were treated by EVAR with percutaneous access and local anesthesia, from which 95% (19) presented with abdominal aortic aneurysm...

  5. Supraglottoplasty for laryngomalacia with obstructive sleep apnea: A systematic review and meta-analysis

    Camacho, M; Dunn, B; Torre, C; Sasaki, J; Gonzales, R; Liu, SC; Chan, DK; Certal, V; Cable, BB
    OBJECTIVES/HYPOTHESIS: To determine if apnea-hypopnea index (AHI) and lowest oxygen saturation (LSAT) improve following isolated supraglottoplasty for laryngomalacia with obstructive sleep apnea (OSA) in children. STUDY DESIGN: Systematic review and meta-analysis. METHODS: Nine databases, including PubMed/MEDLINE, were searched through September 30, 2015. RESULTS: A total of 517 studies were screened; 57 were reviewed; and 13 met criteria. One hundred thirty-eight patients were included (age range: 1 month-12.6 years). Sixty-four patients had sleep exclusive laryngomalacia, and in these patients: 1) AHI decreased from a mean (M) ± standard deviation (SD) of 14.0 ± 16.5 (95% confidence interval [CI] 10.0, 18.0) to 3.3 ± 4.0 (95% CI 2.4, 4.4)...

  6. Awake examination versus DISE for surgical decision making in patients with OSA: A systematic review

    Certal, VF; Pratas, R; Guimarães, L; Lugo, R; Tsou, Y; Camacho, M; Capasso, R
    OBJECTIVE: Traditionally, upper airway examination is performed while the patient is awake. However, in the past two decades, drug-induced sleep endoscopy (DISE) has been used as a method of tridimensional evaluation of the upper airway during pharmacologically induced sleep. This study aimed to systematically review the evidence regarding the usefulness of DISE compared with that of traditional awake examination for surgical decision making in patients with obstructive sleep apnea (OSA). DATA SOURCES: Scopus, PubMed, and Cochrane Library databases were searched. REVIEW METHODS: Only studies with a primary objective of evaluating the usefulness of DISE for surgical decision making in patients with OSA were selected. The...

  7. Usefulness of the Hepatocyte Growth Factor as a Predictor of Mortality in Patients Hospitalized With Acute Heart Failure Regardless of Ejection Fraction

    Pérez-Calvo, JI; Morales-Rull, JL; Gimeno-Orna, JA; Lasierra-Díaz, P; Josa-Laorden, C; Puente-Lanzarote, JJ; Bettencourt, P; Pascual-Figal, DA
    Hepatocyte growth factor (HGF) plays a role in the improvement of cardiac function and remodeling. Their serum levels are strongly related with mortality in chronic systolic heart failure (HF). The aim of this study was to study prognostic value of HGF in acute HF, interaction with ejection fraction, renal function, and natriuretic peptides. We included 373 patients (age 76 ± 10 years, left ventricular ejection fraction [LVEF] 46 ± 14%, 48% men) consecutively admitted for acute HF. Blood samples were obtained at admission. All patients were followed up until death or close of study (>1 year, median 371 days). HGF concentrations were determined...

  8. The Diet of Preschool Children in the Mediterranean Countries of the European Union: A Systematic Review

    Pereira-da-Silva, L; Rêgo, CA; Pietrobelli, A
    This systematic review discusses data on the dietary intake of preschool children living in the Mediterranean countries of the European Union, including the comparison with a Mediterranean-like diet and the association with nutritional status. Specifically, data from the multinational European Identification and Prevention on Dietary and life style induced health effects in children and infants (IDEFICS) study and national studies, such as the Estudo do Padrão Alimentar e de Crescimento Infantil (EPACI) study and Geração XXI cohort in Portugal, ALimentando la SAlud del MAñana (ALSALMA) study in Spain, Étude des Déterminants pré-et postnatals précoces du développement et de la santé...

  10. Fetal-maternal interface impedance parallels local NADPH oxidase related superoxide production.

    Guedes-Martins, L; Silva, E; Gaio, AR; Saraiva, J; Soares, AI; Afonso, J; Macedo, F; Almeida, H
    Blood flow assessment employing Doppler techniques is a useful procedure in pregnancy evaluation, as it may predict pregnancy disorders coursing with increased uterine vascular impedance, as pre-eclampsia. While the local causes are unknown, emphasis has been put on reactive oxygen species (ROS) excessive production. As NADPH oxidase (NOX) is a ROS generator, it is hypothesized that combining Doppler assessment with NOX activity might provide useful knowledge on placental bed disorders underlying mechanisms. A prospective longitudinal study was performed in 19 normal course, singleton pregnancies. Fetal aortic isthmus (AoI) and maternal uterine arteries (UtA) pulsatility index (PI) were recorded at two...

  11. Predictors of Nasal Obstruction: Quantification and Assessment Using Multiple Grading Scales

    Camacho, M; Zaghi, S; Certal, V; Abdullatif, J; Modi, R; Sridhara, S; Tolisano, AM; Chang, ET; Cable, BB; Capasso, R
    Objective. To evaluate the association between nasal obstruction and (1) demographic factors, (2) medical history, (3) physical tests, and (4) nasal exam findings. Study Design. CASE SERIES: Methods. Chart review at a tertiary medical center. Results. Two hundred-forty consecutive patients (52.1 ± 17.5 years old, with a Nasal Obstruction Symptom Evaluation (NOSE) score of 32.0 ± 24.1) were included. Demographic factors and inferior turbinate sizes were not associated with NOSE score or Nasal Obstruction Visual Analog Scale (NO-VAS). A significant association was found between higher NOSE score on univariate analysis and positive history of nasal trauma (p = 0.0136), allergic rhinitis (p...

  13. Assessment of asthma control using CARAT in patients with and without Allergic Rhinitis: A pilot study in primary care.

    Domingos, M; Amaral, R; Fonseca, JA; Azevedo, P; Correia-de-Sousa, J
    BACKGROUND: Asthma and Allergic Rhinitis (AR) are two chronic inflammatory diseases that are often concomitant. The Control of Allergic Rhinitis and Asthma Test (CARAT) was developed to evaluate the control of these diseases from the patients' perspective. Its performance in asthma patients without AR has not been previously studied. AIM: To test the hypothesis that CARAT can be used to assess asthma control in patients with asthma and without AR. METHODS: A cross-sectional study was conducted in 3 primary healthcare centres in Northern Portugal. Adult patients identified in the Electronic Patient Record with a diagnosis of asthma were invited to participate. CARAT was used to...
