181. Prevalence of pulmonary embolism in acute exacerbations of COPD: a systematic review and metaanalysis.
Nearly 30% of all exacerbations of COPD do not have a clear etiology. Although pulmonary embolism (PE) can exacerbate respiratory symptoms such as dyspnea and chest pain, and COPD patients are at a high risk for PE due to a variety of factors including limited mobility, inflammation, and comorbidities, the prevalence of PE during exacerbations is uncertain.

来源: Chest. 2008年134卷2期237-249页
Venous thromboembolism (VTE) is an important complication of neurosurgery. Current guidelines recommend pharmacologic prophylaxis in this setting with either unfractionated heparin or low-molecular-weight heparin (LMWH). We conducted a systematic review asking, "Among patients undergoing neurosurgical procedures, how safe and effective is the prophylactic use of heparin and mechanical devices?"
183. Does central venous pressure predict fluid responsiveness? A systematic review of the literature and the tale of seven mares.
Central venous pressure (CVP) is used almost universally to guide fluid therapy in hospitalized patients. Both historical and recent data suggest that this approach may be flawed.
184. Safety of long-acting beta-agonists in stable COPD: a systematic review.
Some studies have suggested that use of long-acting beta(2)-agonists (LABAs) leads to an increased risk for adverse events in patients with stable COPD. The purpose of this review was to assess the safety, and secondarily the efficacy of LABAs.
185. Contemporary management of acute exacerbations of COPD: a systematic review and metaanalysis.
Systemic corticosteroids, antibiotics, and noninvasive positive pressure ventilation (NPPV) are recommended for patients with acute exacerbation of COPD. However, their clinical benefits in various settings are uncertain. We undertook a systematic review and metaanalysis to systematically evaluate the effectiveness of these therapies.
186. Is the mortality higher in the pulmonary vs the extrapulmonary ARDS? A meta analysis.
作者: Ritesh Agarwal.;Rajagopala Srinivas.;Alok Nath.;Surinder K Jindal.
来源: Chest. 2008年133卷6期1463-1473页
ARDS can occur from the following two pathogenetic pathways: a direct pulmonary injury (ARDSp); and an indirect injury (ARDSexp). The predisposing clinical factor can influence the pathogenesis and clinical outcome of ARDS. This metaanalysis was aimed at evaluating whether there is any difference in mortality between the two groups.
187. Metaanalysis of the efficacy of sublingual immunotherapy in the treatment of allergic asthma in pediatric patients, 3 to 18 years of age.

来源: Chest. 2008年133卷3期599-609页
Recent studies have documented the efficacy and safety of sublingual immunotherapy (SLIT) in patients with rhinitis, but the value of this treatment in those with asthma is still debated. We evaluated the efficacy of SLIT in the treatment of allergic asthma in children by a metaanalysis of randomized, double-blind, and placebo-controlled (DBPC) clinical trials.
188. Differences between low-molecular-weight and unfractionated heparin for venous thromboembolism prevention following ischemic stroke: a metaanalysis.
Venous thromboembolism (VTE) remains a major cause of morbidity following stroke. The optimal form of pharmacologic prophylaxis following stroke is unknown.
189. No difference in risk for thrombocytopenia during treatment of pulmonary embolism and deep venous thrombosis with either low-molecular-weight heparin or unfractionated heparin: a metaanalysis.
作者: Timothy A Morris.;Selene Castrejon.;Gehan Devendra.;Anthony C Gamst.
来源: Chest. 2007年132卷4期1131-9页
Low-molecular-weight heparin (LMWH) is a popular alternative to unfractionated heparin (UH) for the treatment of pulmonary embolism (PE) and deep vein thrombosis (DVT), in part based on the perception of a lower risk for heparin-induced thrombocytopenia (HIT). To investigate the evidence supporting this perception, we performed a metaanalysis to compare the incidence of thrombocytopenia between LMWH and UH during PE and/or DVT treatment.
190. Comparison of first-line with second-line antibiotics for acute exacerbations of chronic bronchitis: a metaanalysis of randomized controlled trials.
作者: George Dimopoulos.;Ilias I Siempos.;Ioanna P Korbila.;Katerina G Manta.;Matthew E Falagas.
来源: Chest. 2007年132卷2期447-55页
Although acute exacerbations of chronic bronchitis (AECBs) are common, there has been no metaanalysis that focused on the optimum regimen.
191. Analyzing the short-term effect of placebo therapy in pulmonary arterial hypertension: potential implications for the design of future clinical trials.
作者: Donald L Helman.;Alexander W Brown.;Jeffrey L Jackson.;Andrew F Shorr.
来源: Chest. 2007年132卷3期764-72页
Placebo is commonly used in short-term randomized trials for pulmonary arterial hypertension (PAH). Currently, outcome data regarding placebo are lacking. We conducted a systematic review and performed a metaanalysis to assess its effect.
192. Diagnostic value of interferon-gamma in tuberculous pleurisy: a metaanalysis.
作者: Jing Jiang.;Huan-Zhong Shi.;Qiu-Li Liang.;Shou-Ming Qin.;Xue-Jun Qin.
来源: Chest. 2007年131卷4期1133-41页
Conventional tests are not always helpful in making a diagnosis of tuberculous pleurisy. Many studies have investigated the usefulness of interferon (IFN)-gamma measurements in pleural fluid for the early diagnosis of tuberculous pleurisy. We conducted a metaanalysis to determine the accuracy of IFN-gamma measurements in the diagnosis of tuberculous pleurisy.
193. Endoscopic ultrasound-guided fine-needle aspiration for non-small cell lung cancer staging: A systematic review and metaanalysis.
作者: Carlos G Micames.;Douglas C McCrory.;Darren A Pavey.;Paul S Jowell.;Frank G Gress.
来源: Chest. 2007年131卷2期539-48页
Endoscopic ultrasound (EUS)-guided fine-needle aspiration (FNA) is a minimally invasive alternative technique for mediastinal staging of non-small cell lung cancer. A metaanalysis was performed to estimate the diagnostic accuracy of EUS-FNA for staging mediastinal lymph nodes (N2/N3 disease) in patients with lung cancer.
194. Twice vs three times daily heparin dosing for thromboembolism prophylaxis in the general medical population: A metaanalysis.
作者: Christopher S King.;Aaron B Holley.;Jeffrey L Jackson.;Andrew F Shorr.;Lisa K Moores.
来源: Chest. 2007年131卷2期507-16页
Prophylaxis with unfractionated heparin (UFH) has been proven to reduce rates of venous thromboembolism (VTE) in hospitalized medical patients. While twice-daily (BID) and three-times-daily (TID) dosing regimens have been studied, the two have never been directly compared. We performed a metaanalysis to assess whether TID is superior to BID dosing in the prevention of VTE.
195. Respiratory physiotherapy to prevent pulmonary complications after abdominal surgery: a systematic review.

来源: Chest. 2006年130卷6期1808-16页
To evaluate whether the incidence of recurrent venous thromboembolism (VTE) events after therapy differs for patients treated with long-term low-molecular-weight heparin (LMWH) or oral anticoagulant therapy (OAT).
197. How frequently is venous thromboembolism in heparin-treated patients associated with heparin-induced thrombocytopenia?
Patients receiving heparin for thromboprophylaxis or treatment may have new or recurrent venous thromboembolism (VTE) if immune-mediated heparin-induced thrombocytopenia (HIT) occurs or for other reasons, eg, if anticoagulation fails. We estimated from the literature how frequently a patient presenting with VTE during or following heparin therapy has HIT-associated VTE.
198. Cardiovascular function following surgical repair of pectus excavatum: a metaanalysis.

来源: Chest. 2006年130卷2期506-16页
Despite numerous published reports, there is no consensus in the literature as to whether the surgical repair of the pectus excavatum improves cardiovascular function. As a result, it has been suggested that correction should be considered a cosmetic procedure, and therefore, many health insurance companies have questioned whether the repair of the pectus excavatum improves cardiovascular function and thus are reluctant to authorize the procedure. The purpose of this study was to apply metaanalysis methodology to generate a quantitative synthesis of the effects of surgical repair on cardiovascular function and to test the hypothesis that surgical repair of the pectus excavatum results in significant improvements in cardiovascular function.
199. Intrapleural fibrinolytic agents for empyema and complicated parapneumonic effusions: a meta-analysis.

来源: Chest. 2006年129卷3期783-90页
Randomized controlled trials have shown conflicting findings about the role of intrapleural fibrinolytic therapy for the treatment of empyema and complicated parapneumonic effusions in adult patients.
