RESUMEN
OBJECTIVES: This study aimed to review definitions of digital health and understand their relevance for health outcomes research. Four umbrella terms (digital health, electronic health, mobile health, and telehealth/telemedicine) were summarized in this article. METHODS: PubMed/MEDLINE, Embase, Cochrane Library, and EconLit were searched from January 2015 to May 2020 for systematic reviews containing key Medical Subject Headings terms for digital health (n = 38) and synonyms of "definition." Independent pairs of reviewers performed each stage of the review, with reconciliation by a third reviewer if required. A single reviewer consolidated each definition for consistency. We performed text analysis via word clouds and computed document frequency-and inverse corpus frequency scores. RESULTS: The search retrieved 2610 records with 545 articles (20.9%) taken forward for full-text review. Of these, 39.3% (214 of 545) were eligible for data extraction, of which 134 full-text articles were retained for this analysis containing 142 unique definitions of umbrella terms (digital health [n = 4], electronic health [n = 36], mobile health [n = 50], and telehealth/telemedicine [n = 52]). Seminal definitions exist but have increasingly been adapted over time and new definitions were created. Nevertheless, the most characteristic words extracted from the definitions via the text analyses still showed considerable overlap between the 4 umbrella terms. CONCLUSIONS: To focus evidence summaries for outcomes research purposes, umbrella terms should be accompanied by Medical Subject Headings terms reflecting population, intervention, comparator, outcome, timing, and setting. Ultimately a functional classification system is needed to create standardized terminology for digital health interventions denoting the domains of patient-level effects and outcomes.

Graphene and its derivatives have shown fascinating potential in biomedical applications. However, the biocompatibility of graphene with vascular smooth muscle cells (VSMCs) and applications to vascular engineering have not been explored extensively. Using a rat aortic smooth muscle cell line, A7r5, as a VSMC model, we have explored the effects of graphene oxide (GO) on the growth and behaviours of VSMCs. Results demonstrated that GO had no obvious toxicity to VSMCs. Cells cultured on GO retained the expression of smooth muscle cell-specific markers CNN1, ACTA2 and SMTN, on both mRNA and protein levels. A wound healing assay demonstrated no effect of GO on cell migration. We also found that small-flaked GO favoured the proliferation of VSMCs, suggesting a potential of using surface chemistry or physical properties of GO to influence cell growth behaviour. These results provide insight into the suitability of GO as a scaffold for vascular tissue engineering.

BACKGROUND: Biologic disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs are used in patients with psoriatic arthritis (PsA), but few studies directly compare their clinical efficacy. In such situations, network meta-analysis (NMA) can inform evidence-based decision-making. OBJECTIVE: To evaluate the comparative efficacy and safety of approved bDMARDs in patients with PsA. METHODS: Bayesian NMA was conducted to compare the clinical efficacy of bDMARDs at weeks 12â16 in bDMARD-naïve patients with PsA in terms of American College of Rheumatology (ACR) criteria, Psoriatic Arthritis Response Criteria (PsARC) and Psoriasis Area and Severity Index (PASI). Safety end points were evaluated in the overall mixed population of bDMARD-naive and bDMARD-experienced patients. RESULTS: For ACR, all treatments except abatacept were statistically superior to placebo. Infliximab was most effective, followed by golimumab and etanercept, which were statistically superior to most other treatments. Ixekizumab 80 mg every 2 weeks (Q2W) was statistically superior to abatacept subcutaneous, apremilast and both regimens of ustekinumab; similar findings were observed for ixekizumab 80 mg Q4W. For PsARC response, ixekizumab did not significantly differ from other therapies, except for golimumab, infliximab and etanercept, which were superior to most other agents including ixekizumab. For PASI response, infliximab was numerically most effective, but was not statistically superior to ixekizumab, which was the next best performing agent. Analysis of safety end points identified few differences between treatments. CONCLUSION: Our NMA confirms the efficacy and acceptable safety profile of bDMARDs in patients with active PsA. There were generally few statistically significant differences between most treatments.

Asthma is a chronic respiratory disease that is widespread throughout the US population and disproportionately affects children. This literature review aimed to identify recent information regarding the economic burden of pediatric asthma in the US. MEDLINE, EMBASE, Econlit, and PsycINFO databases and gray literature sources were searched from January 2012 to January 2018 to capture relevant publications. Publications reporting on healthcare resource utilization and/or healthcare costs of pediatric asthma were included (n = 8). Total direct costs of pediatric asthma were US$5.92 billion in 2013. Average annual costs per child ranged from US$3076 to US$13612. Across studies, pharmacy (US$1027-2120), inpatient (US$337-2016) and outpatient (US$1049-8039) costs were the primary contributors to healthcare costs. Inpatient and emergency department (ED) visits exerted a high economic burden. For instance, the national annual cost of asthma-related hospitalizations was estimated at US$1.59 billion in 2009, while estimates of costs-per-hospitalization (2010) and charges-per-discharge (2009) were US$3600 and US$8406, respectively. The total cost of ED visits to Medicaid was estimated at US$272 million in 2010. In a mixed-insurance population, ED cost estimates ranged from US$152 to US$172 annually per patient. Invariably, costs for children with asthma were significantly greater than for children without. Pediatric asthma imposes a significant economic burden to the US healthcare system. Children with asthma have significantly higher healthcare resource utilization and costs than children without asthma.
