Perioperative Beta-Blocker Therapy And Mortality After Major Noncardiac Surgery, Peter K. Lindenauer, Penelope Susan Pekow, Kaijun Wang, Dheeresh K. Mamidi, Benjamin Gutierrez, Evan M. Benjamin

Peter Lindenauer MD

Background: Despite limited evidence from randomized trials, perioperative treatment with beta-blockers is now widely advocated. We assessed the use of perioperative beta-blockers and their association with in-hospital mortality in routine clinical practice.

Methods: We conducted a retrospective cohort study of patients 18 years of age or older who underwent major noncardiac surgery in 2000 and 2001 at 329 hospitals throughout the United States. We used propensity-score matching to adjust for differences between patients who received perioperative beta-blockers and those who did not receive such therapy and compared in-hospital mortality using multivariable logistic modeling.

Results: Of 782,969 patients, 663,635 (85 percent) …

Does Sex Influence The Impact That Smoking, Treatment Interruption And Impaired Pulmonary Function Have On Outcomes In Limited Stage Small Cell Lung Cancer Treatment?, Gregory Videtic, Pauline Truong, Robert Ash, Edward Yu, Walter Kocha, Mark Vincent, Anna Tomiak, A Dar, Frances Whiston, Larry Stitt

Edward Yu

PURPOSE: To look for survival differences between men and women with limited stage small cell lung cancer (LS-SCLC) by examining stratified variables that impair treatment efficacy. METHODS: A retrospective review of 215 LS-SCLC patients treated from 1989 to 1999 with concurrent chemotherapy-radiotherapy modelled on the 'early-start' thoracic radiotherapy arm of a National Cancer Institute of Canada randomized trial. RESULTS: Of 215 LS-SCLC patients, 126 (58.6%) were men and 89 (41.4%) were women. Smoking status during treatment for 186 patients (86.5%) was: 107 (58%) nonsmoking (NS) (76 [71%] male [M]; 31 [29%] female [F]) and 79 (42%) smoking (S) (36 M …

Este artigo tem como objetivo conhecer o perfil das gestantes adolescentes em consulta de enfermagem, ao primeiro atendimento da assistência ao Pré-natal na Clínica Materno Infantil em Sarandi – PR. Realizou-se um estudo descritivo no período de 23/09/2003 a 21/06/20004, avaliando o perfil das gestantes adolescentes através da investigação e análise de fichas perinatais dos prontuários de gestantes. Observamos a prevalência de evasão escolar entre as adolescentes que encontravam-se grávidas, além de iniciam o pré-natal mais cedo em relação as multíparas. Entretanto há uma preocupação em relação a idade gestacional de início do pré-natal pois podem haver fatores de risco …

A Wintertime Study Of Pahs In Fine And Coarse Aerosols In Sa˜O Paulo City, Brazil, Paulo A. Lotufo

Paulo A Lotufo

The Polycyclic aromatic hydrocarbons PAHs (naphthalene, acenaphthylene, acenaphthene, phenanthrene, fluoranthene, pyrene, benzo(a)anthracene, chrysene, benzo(b)fluoranthene, benzo(k)fluoranthene, benzo(a)pyrene, indeno(1,2,3-cd)pyrene and benzo(ghi)perylene) concentrations in fine (PM2.5) and coarse (PM2.5–10) atmospheric particulate matter were measured at Sa˜o Paulo city, Brazil. The dominant PAHcompounds were indeno(1,2,3-cd)pyrene, benzo(ghi)perylene and benzo(b)fluoranthene for both the fractions. The calculated ratios of some specific PAHs were in close agreement with those attributed to direct emissions of car exhaust. The factor analysis for PM2.5 produced four factors: Factor 1 was attributed to diesel emissions, Factor 2 was attributed to stationary combustion source, Factor 3 was attributed to vehicular emissions and Factor …
