Cochrane Handbook for Systematic Reviews of Interventions

Chronic obstructive pulmonary disease (COPD) remains a major public health problem. It is the fourth leading cause of chronic morbidity and mortality in the United States, and is projected to rank fifth in 2020 in burden of disease worldwide, according to a study published by the World Bank/World Health Organization. Yet, COPD remains relatively unknown or ignored by the public as well as public health and government officials. In 1998, in an effort to bring more attention to COPD, its management, and its prevention, a committed group of scientists encouraged the U.S. National Heart, Lung, and Blood Institute and the World Health Organization to form the Global Initiative for Chronic Obstructive Lung Disease (GOLD). Among the important objectives of GOLD are to increase awareness of COPD and to help the millions of people who suffer from this disease and die prematurely of it or its complications. The first step in the GOLD program was to prepare a consensus report, Global Strategy for the Diagnosis, Management, and Prevention of COPD, published in 2001. The present, newly revised document follows the same format as the original consensus report, but has been updated to reflect the many publications on COPD that have appeared. GOLD national leaders, a network of international experts, have initiated investigations of the causes and prevalence of COPD in their countries, and developed innovative approaches for the dissemination and implementation of COPD management guidelines. We appreciate the enormous amount of work the GOLD national leaders have done on behalf of their patients with COPD. Despite the achievements in the 5 years since the GOLD report was originally published, considerable additional work is ahead of us if we are to control this major public health problem. The GOLD initiative will continue to bring COPD to the attention of governments, public health officials, health care workers, and the general public, but a concerted effort by all involved in health care will be necessary.

The UK Biobank project is a prospective cohort study with deep genetic and phenotypic data collected on approximately 500,000 individuals from across the United Kingdom, aged between 40 and 69 at recruitment. The open resource is unique in its size and scope. A rich variety of phenotypic and health-related information is available on each participant, including biological measurements, lifestyle indicators, biomarkers in blood and urine, and imaging of the body and brain. Follow-up information is provided by linking health and medical records. Genome-wide genotype data have been collected on all participants, providing many opportunities for the discovery of new genetic associations and the genetic bases of complex traits. Here we describe the centralized analysis of the genetic data, including genotype quality, properties of population structure and relatedness of the genetic data, and efficient phasing and genotype imputation that increases the number of testable variants to around 96 million. Classical allelic variation at 11 human leukocyte antigen genes was imputed, resulting in the recovery of signals with known associations between human leukocyte antigen alleles and many diseases.

Thorax had a good 2013. We were all buoyed by a large rise in our impact factor from 6.525 to 8.376, by far the largest rise seen in our specialty area, cementing our position as the second-ranked respiratory journal behind the American Journal of Respiratory and Critical Care Medicine (impact factor 11.041). We suspect this has led to an increase in submission of high-quality manuscripts and are hopeful that gains in impact factor will increase. In part our improved impact factor reflects a reduction in original articles published per edition from 10–12 to 8–10 with the introduction of new content published in the ‘Chest Clinic’ section aimed at the jobbing clinician without a major research interest. However, the tremendous hard work of the associate editors, deputy editors, reviewers and the editorial team and the high-quality manuscripts sent in by you, our readers, have been much more important and hugely appreciated factors.

The acceptance rate for original articles is now 11% and the overall acceptance rate is 23%. Editorial turnaround times continue to improve. The average time to first decision in 2013 was 19 days for all papers and the average time to first decision for reviewed papers was 40 days, a modest improvement from 2012. The instant reject rate has reduced from 43% to 37%. We have seen an increase in time from on-line publication to paper publication …

Progress to be made in asthma management.

Purpose Chronic rhinosinusitis with nasal polyps (CRSwNP) is a predominantly type 2 inflammatory disease frequently coexisting with other type 2 conditions including asthma and non-steroidal anti-inflammatory drug-exacerbated respiratory disease (NSAID-ERD). Coexisting asthma leads to increased CRSwNP symptom burden. Dupilumab, a monoclonal antibody that blocks the shared receptor component for interleukin-4 and -13, demonstrated efficacy in adults with severe CRSwNP in the Phase 3 SINUS-24 (NCT02912468) and SINUS-52 (NCT02898454) studies, including in patients with coexisting asthma/NSAID-ERD. However, the impact of different asthma characteristics on dupilumab treatment in this population is unknown. We report CRSwNP and asthma outcomes with dupilumab in patients with CRSwNP and coexisting asthma according to baseline asthma characteristics. Methods Change from baseline at Week 24 (pooled studies) and Week 52 (SINUS-52) in CRSwNP outcomes (nasal polyp score, nasal congestion, 22-item Sino-Nasal Outcome Test [SNOT-22], loss of smell score, University of Pennsylvania Smell Identification Test) and asthma outcomes (5-item Asthma Control Questionnaire [ACQ-5], pre-bronchodilator forced expiratory volume in 1 second [FEV1]) were analyzed post hoc for placebo and dupilumab 300 mg every 2 weeks according to baseline blood eosinophils ≥150/≥300 cells/µL, ACQ-5 scores <1.5/≥1.5, and FEV1 <80%. Results In the pooled studies, 428/724 patients (59.1%) had coexisting asthma, of which 181/428 (42.3%) had coexisting NSAID-ERD. Dupilumab significantly improved all CRSwNP and asthma outcomes vs placebo at Week 24 (P < 0.001) regardless of baseline eosinophil or ACQ-5 category, or FEV1 <80%. Similar magnitude of improvement was seen at Week 52 (SINUS-52) and in patients with NSAID-ERD (pooled studies, Week 24). By Week 24, improvements with dupilumab exceeded the minimum clinically important differences for ACQ-5 and SNOT-22 in 35.2% to 74.2% and 72.0% to 78.7% of patients, respectively. Conclusion Dupilumab improved CRSwNP outcomes in patients with CRSwNP and coexisting asthma, and improved asthma outcomes, regardless of differences in baseline asthma characteristics.
