Objective

To review the literature systematically and perform meta-analyses to address these questions: 1) Is there evidence that self-measured blood pressure (BP) without other augmentation is superior to office-based measurement of BP for achieving better BP control or for preventing adverse clinical outcomes that are related to elevated BP? 2) What is the optimal target for BP lowering during antihypertensive therapy in adults? 3) In adults with hypertension, how do various antihypertensive drug classes differ in their benefits and harms compared with each other as first-line therapy?

Methods

Electronic literature searches were performed by Doctor Evidence, a global medical evidence software and services company, across PubMed and EMBASE from 1966 to 2015 using key words and relevant subject headings for randomized controlled trials that met eligibility criteria defined for each question. We performed analyses using traditional frequentist statistical and Bayesian approaches, including random-effects Bayesian network meta-analyses.

Results

Our results suggest that: 1) There is a modest but significant improvement in systolic BP in randomized controlled trials of self-measured BP versus usual care at 6 but not 12 months, and for selected patients and their providers self-measured BP may be a helpful adjunct to routine office care. 2) systolic BP lowering to a target of <130 mm Hg may reduce the risk of several important outcomes including risk of myocardial infarction, stroke, heart failure, and major cardiovascular events. No class of medications (i.e., angiotensin-converting enzyme inhibitors, angiotensin-receptor blockers, calcium channel blockers, or beta blockers) was significantly better than thiazides and thiazide-like diuretics as a first-line therapy for any outcome.  相似文献

Performance of rheumatoid arthritis (RA) classification by the 2010 American College of Rheumatology (ACR)/European League against Rheumatism (EULAR) criteria, compared to the 1987 ACR criteria, has not been assessed in population-based cohorts in which disease identification is by mailed questionnaire. Women followed in the Nurses’ Health Study and Nurses’ Health Study II cohorts self-reported new doctor-diagnosed RA on biennial questionnaires. Two RA experts reviewed medical records of 128 new RA self-reports to obtain individual 1987 and 2010 criteria and arrived at a consensus opinion. We compared agreement in classification by the two criteria sets (kappa), and calculated sensitivity and specificity, with reviewers’ opinion as gold standard. Ninety-eight (77 %) participants were classified as RA by reviewers’ consensus opinion; 98 (77 %) fulfilled 1987 criteria, while 79 (63 %) fulfilled 2010 criteria. Seventy-two (56 %) were classified as RA by both sets, 21 (16 %) by neither, 26 (20 %) by only 1987 criteria, and 9 (7 %) by only 2010 criteria. Kappa for concordance was 0.36 (95 % CI 0.20–0.53). Compared to reviewer’s opinion, sensitivity and specificity were 0.93 and 0.77 for 1987 criteria, and 0.79 and 0.87 for 2010 criteria. Participants fulfilling 1987 criteria only were more likely to be seronegative. In these prospective population-based cohorts, significant discordance between 1987 ACR and 2010 ACR/EULAR criteria for classifying RA exists. Using the 2010 ACR/EULAR criteria alone had decreased sensitivity, and seronegative RA cases would be excluded in particular. Combined use of both will be necessary to maximize inclusion and allow sensitivity analyses.  相似文献

Although the attention of the world and the global health community specifically is deservedly focused on the COVID-19 pandemic, other determinants of health continue to have large impacts and may also interact with COVID-19. Air pollution is one crucial example. Established evidence from other respiratory viruses and emerging evidence for COVID-19 specifically indicates that air pollution alters respiratory defense mechanisms leading to worsened infection severity. Air pollution also contributes to co-morbidities that are known to worsen outcomes amongst those infected with COVID-19, and air pollution may also enhance infection transmission due to its impact on more frequent coughing. Yet despite the massive disruption of the COVID-19 pandemic, there are reasons for optimism: broad societal lockdowns have shown us a glimpse of what a future with strong air pollution measures could yield. Thus, the urgency to combat air pollution is not diminished, but instead heightened in the context of the pandemic.  相似文献
