521. Do findings on routine examination identify patients at risk for primary open-angle glaucoma? The rational clinical examination systematic review.

作者: Hussein Hollands.;Davin Johnson.;Simon Hollands.;David L Simel.;Delan Jinapriya.;Sanjay Sharma.
来源: JAMA. 2013年309卷19期2035-42页
Glaucoma is the second leading cause of blindness worldwide, and its insidious onset is often associated with diagnostic delay. Since glaucoma progression can often be effectively diminished when treated, identifying individuals at risk for glaucoma could potentially lead to earlier detection and prevent associated vision loss.

522. Elective cesarean delivery on maternal request.

作者: Jeffrey Ecker.
来源: JAMA. 2013年309卷18期1930-6页
Some pregnant women prefer cesarean delivery and request it without maternal or fetal indication rather than proceeding with a plan for vaginal delivery.

Allergic rhinitis affects up to 40% of the US population. To desensitize allergic individuals, subcutaneous injection immunotherapy or sublingual immunotherapy may be administered. In the United States, sublingual immunotherapy is not approved by the Food and Drug Administration. However, some US physicians use aqueous allergens, off-label, for sublingual desensitization.

526. Computed tomography screening for lung cancer.

作者: Phillip M Boiselle.
来源: JAMA. 2013年309卷11期1163-70页
Low-dose computed tomography (CT) screening was shown to reduce lung cancer-specific mortality in a large randomized trial of a high-risk population. The decision to pursue CT screening for lung cancer is a timely question raised by individuals at risk of lung cancer and by their health care practitioners.

527. Antiplatelet therapy to prevent cardiovascular events and mortality in patients with intermittent claudication.

作者: Peng Foo Wong.;Lee-Yee Chong.;Gerard Stansby.
来源: JAMA. 2013年309卷9期926-7页
Do antiplatelet therapies reduce risk of all-cause mortality, cardiovascular disease (CVD) mortality, and cardiovascular events in patients with intermittent claudication? Which antiplatelet is most strongly associated with a reduced risk of all-cause and CVD mortality?

528. Chronic back pain with possible prescription opioid misuse.

作者: Daniel P Alford.
来源: JAMA. 2013年309卷9期919-25页
Data on the effectiveness and safety of long-term opioid therapy for chronic pain are limited. Opioid adherence monitoring includes urine drug testing. Determining whether a patient's opioid prescription should be discontinued after an unexpected urine test result can be clinically complex.

The CONSORT (Consolidated Standards of Reporting Trials) Statement aims to improve the reporting of randomized controlled trials (RCTs); however, it lacks guidance on the reporting of patient-reported outcomes (PROs), which are often inadequately reported in trials, thus limiting the value of these data. In this article, we describe the development of the CONSORT PRO extension based on the methodological framework for guideline development proposed by the Enhancing the Quality and Transparency of Health Research (EQUATOR) Network. Five CONSORT PRO checklist items are recommended for RCTs in which PROs are primary or important secondary end points. These recommendations urge that the PROs be identified as a primary or secondary outcome in the abstract, that a description of the hypothesis of the PROs and relevant domains be provided (ie, if a multidimensional PRO tool has been used), that evidence of the PRO instrument's validity and reliability be provided or cited, that the statistical approaches for dealing with missing data be explicitly stated, and that PRO-specific limitations of study findings and generalizability of results to other populations and clinical practice be discussed. Examples and an updated CONSORT flow diagram with PRO items are provided. It is recommended that the CONSORT PRO guidance supplement the standard CONSORT guidelines for reporting RCTs with PROs as primary or secondary outcomes. Improved reporting of PRO data should facilitate robust interpretation of the results from RCTs and inform patient care.

530. Insomnia.

作者: Daniel J Buysse.
来源: JAMA. 2013年309卷7期706-16页
Insomnia is one of the most prevalent health concerns in the population and in clinical practice. Clinicians may be reluctant to address insomnia because of its many potential causes, unfamiliarity with behavioral treatments, and concerns about pharmacologic treatments.

531. Association of hydroxyethyl starch administration with mortality and acute kidney injury in critically ill patients requiring volume resuscitation: a systematic review and meta-analysis.

作者: Ryan Zarychanski.;Ahmed M Abou-Setta.;Alexis F Turgeon.;Brett L Houston.;Lauralyn McIntyre.;John C Marshall.;Dean A Fergusson.
来源: JAMA. 2013年309卷7期678-88页
Hydroxyethyl starch is commonly used for volume resuscitation yet has been associated with serious adverse events, including acute kidney injury and death. Clinical trials of hydroxyethyl starch are conflicting. Moreover, multiple trials from one investigator have been retracted because of scientific misconduct.

532. Intermittent preventive therapy for malaria during pregnancy using 2 vs 3 or more doses of sulfadoxine-pyrimethamine and risk of low birth weight in Africa: systematic review and meta-analysis.

作者: Kassoum Kayentao.;Paul Garner.;Anne Maria van Eijk.;Inbarani Naidoo.;Cally Roper.;Abdunoor Mulokozi.;John R MacArthur.;Mari Luntamo.;Per Ashorn.;Ogobara K Doumbo.;Feiko O ter Kuile.
来源: JAMA. 2013年309卷6期594-604页
Intermittent preventive therapy with sulfadoxine-pyrimethamine to control malaria during pregnancy is used in 37 countries in sub-Saharan Africa, and 31 of those countries use the standard 2-dose regimen. However, 2 doses may not provide protection during the last 4 to 10 weeks of pregnancy, a pivotal period for fetal weight gain.

533. Association of clopidogrel pretreatment with mortality, cardiovascular events, and major bleeding among patients undergoing percutaneous coronary intervention: a systematic review and meta-analysis.

Clopidogrel pretreatment is recommended for patients with acute coronary syndromes (ACS) and stable coronary artery disease who are scheduled for percutaneous coronary intervention (PCI), but whether using clopidogrel as a pretreatment for PCI is associated with positive clinical outcomes has not been established.

534. Association of all-cause mortality with overweight and obesity using standard body mass index categories: a systematic review and meta-analysis.

作者: Katherine M Flegal.;Brian K Kit.;Heather Orpana.;Barry I Graubard.
来源: JAMA. 2013年309卷1期71-82页
Estimates of the relative mortality risks associated with normal weight, overweight, and obesity may help to inform decision making in the clinical setting.

535. Management of varicose veins and venous insufficiency.

作者: Allen Hamdan.
来源: JAMA. 2012年308卷24期2612-21页
Chronic venous disease, reviewed herein, is manifested by a spectrum of signs and symptoms, including cosmetic spider veins, asymptomatic varicosities, large painful varicose veins, edema, hyperpigmentation and lipodermatosclerosis of skin, and ulceration. However, there is no definitive stepwise progression from spider veins to ulcers and, in fact, severe skin complications of varicose veins, even when extensive, are not guaranteed. Treatment options range from conservative (eg, medications, compression stockings, lifestyle changes) to minimally invasive (eg, sclerotherapy or endoluminal ablation), invasive (surgical techniques), and hybrid (combination of ≥1 therapies). Ms L, a 68-year-old woman with varicose veins, is presented. She has had vein problems over the course of her life. Her varicose veins recurred after initial treatment, and she is now seeking guidance regarding her current treatment options.

536. Association between omega-3 fatty acid supplementation and risk of major cardiovascular disease events: a systematic review and meta-analysis.

来源: JAMA. 2012年308卷10期1024-33页
Considerable controversy exists regarding the association of omega-3 polyunsaturated fatty acids (PUFAs) and major cardiovascular end points.

537. Does this adult patient with suspected bacteremia require blood cultures?

作者: Bryan Coburn.;Andrew M Morris.;George Tomlinson.;Allan S Detsky.
来源: JAMA. 2012年308卷5期502-11页
Clinicians order blood cultures liberally among patients in whom bacteremia is suspected, though a small proportion of blood cultures yield true-positive results. Ordering blood cultures inappropriately may be both wasteful and harmful.

538. Acute respiratory distress syndrome: the Berlin Definition.

The acute respiratory distress syndrome (ARDS) was defined in 1994 by the American-European Consensus Conference (AECC); since then, issues regarding the reliability and validity of this definition have emerged. Using a consensus process, a panel of experts convened in 2011 (an initiative of the European Society of Intensive Care Medicine endorsed by the American Thoracic Society and the Society of Critical Care Medicine) developed the Berlin Definition, focusing on feasibility, reliability, validity, and objective evaluation of its performance. A draft definition proposed 3 mutually exclusive categories of ARDS based on degree of hypoxemia: mild (200 mm Hg < PaO2/FIO2 ≤ 300 mm Hg), moderate (100 mm Hg < PaO2/FIO2 ≤ 200 mm Hg), and severe (PaO2/FIO2 ≤ 100 mm Hg) and 4 ancillary variables for severe ARDS: radiographic severity, respiratory system compliance (≤40 mL/cm H2O), positive end-expiratory pressure (≥10 cm H2O), and corrected expired volume per minute (≥10 L/min). The draft Berlin Definition was empirically evaluated using patient-level meta-analysis of 4188 patients with ARDS from 4 multicenter clinical data sets and 269 patients with ARDS from 3 single-center data sets containing physiologic information. The 4 ancillary variables did not contribute to the predictive validity of severe ARDS for mortality and were removed from the definition. Using the Berlin Definition, stages of mild, moderate, and severe ARDS were associated with increased mortality (27%; 95% CI, 24%-30%; 32%; 95% CI, 29%-34%; and 45%; 95% CI, 42%-48%, respectively; P < .001) and increased median duration of mechanical ventilation in survivors (5 days; interquartile [IQR], 2-11; 7 days; IQR, 4-14; and 9 days; IQR, 5-17, respectively; P < .001). Compared with the AECC definition, the final Berlin Definition had better predictive validity for mortality, with an area under the receiver operating curve of 0.577 (95% CI, 0.561-0.593) vs 0.536 (95% CI, 0.520-0.553; P < .001). This updated and revised Berlin Definition for ARDS addresses a number of the limitations of the AECC definition. The approach of combining consensus discussions with empirical evaluation may serve as a model to create more accurate, evidence-based, critical illness syndrome definitions and to better inform clinical care, research, and health services planning.
