The medical burden of heart failure (HF) has spurred interest in clinicians and scientists to develop therapies to restore the function of a failing heart. To advance this agenda, the National Heart, Lung, and Blood Institute (NHLBI) convened a Working Group of experts from June 2 to 3, 2016, in Bethesda, Maryland, to develop NHLBI recommendations aimed at advancing the science of cardiac recovery in the setting of mechanical circulatory support (MCS). MCS devices effectively reduce volume and pressure overload that drives the cycle of progressive myocardial dysfunction, thereby triggering structural and functional reverse remodeling...

Perioperative acute kidney injury is a common problem. While clinical trials seek to evaluate the impact of interventions on a variety of primary and secondary endpoints with the aim of implementing this knowledge to improve perioperative outcomes, the use of valid and relevant endpoints within clinical trials is of critical importance to achieving this goal. Suitable endpoints must be validated for the study population and in light of the clinical context under investigation while also considering regulatory requirements that govern the licensing of new therapeutic agents as well as the values of patients whose outcomes we seek to improve...

In the era of precision medicine, efforts are needed to identify and tailor screening recommendations among elevated-risk patients. Individuals younger than 50years are an important target population, as they comprise 15% of colorectal (CRC) cases and often present with more advanced disease than their 50+ counterparts. In this large study, 2470 patients ages 25-49 used a tablet-based program that assessed risks, matched risks with screening guidelines, and generated tailored printed guideline-concordant recommendations for patients and their providers...

Precision medicine envisions a future of effective diagnosis, treatment, and prevention grounded in precise understandings of the genetic and environmental determinants of disease. Given that the original genome-wide association studies represented a predominately European White population, and that diversity in genomic studies must account for genetic variation both within and across racial categories, new research studies are at a heightened risk for inadequate representation. Currently biological samples are being made available for sequencing in biobanks across the USA, but the diversity of those samples is unknown...

Introduction The prevalence of depression in pregnancy is over 10% and a significant proportion of pregnant women use antidepressant medication. The safety of antidepressants in pregnancy is controversial, partly due to methodological challenges. The conflicting results in the literature may, however, also be due to differences in risks between the study populations related to variations in e.g. degree of depression, type of antidepressant, and lifestyle. Areas covered The literature on the safety of antidepressants in pregnancy is vast and thousands of papers have been published mainly in the last decades...

The present retrospective study was conducted on 1482 women in order to evaluate whether their pre-pregnancy adherence to the Mediterranean diet may affect maternal gestational weight gain (GWG). For this purpose, the study population was classified according to the Institute of Medicine (IOM) recommendations concerning GWG. Pre-pregnancy adherence to the Mediterranean diet was assessed with 11 food patterns groups based on their contribution in the Mediterranean diet pyramid. Women with high adherence to the Mediterranean diet were more frequently characterised by GWG inside the IOM recommendations...

Randomized clinical trials provide the gold standard evidence base to guide clinical practice. Despite major advances in trial design, pediatric clinical trials are still difficult to perform and pose unique challenges, including the need to consider the impact of developmental changes in trial design. Advances within pediatric rheumatology combined with the need to comply with legislative requirements have driven new approaches to performing pediatric clinical trials such as utilization of large research networks, incorporation of patient and family stakeholders in the planning and implementation of clinical trials, and the development of novel trial designs...

Accurate prediction of disease risk based on genetic factors is an important goal in human genetics research and precision medicine. Advanced prediction models will lead to more effective disease prevention and treatment strategies. Despite the identification of thousands of disease-associated genetic variants through genome-wide association studies (GWAS) in the past decade, accuracy of genetic risk prediction remains moderate for most diseases, which is largely due to the challenges in both identifying all the functionally relevant variants and accurately estimating their effect sizes...

High-resolution measurement of medication adherence is essential to personalized drug therapy . An FDA-cleared device, using an edible ingestion sensor (IS), external wearable patch and paired mobile device, can detect and record ingestion events. Oral medications must be combined with an IS to generate precise 'digitized-medication' ingestion records. We developed a GMP-protocol to repackage oral medications with the IS within certified Capsugel® capsules, termed co-encapsulation (CoE). A randomized bioequivalence study of CoE-IS-Rifamate (Isoniazid/Rifampin 150/300mg) versus native-Rifamate was conducted in 12 patients with active Mycobacterium Tuberculosis (MTB) and demonstrated bioequivalence using the population method ratio test (95% CI)...

Concepts and our approaches to stroke prevention in atrial fibrillation (AF) have changed markedly over the last decade. There has been an evolution over the approach to stroke and bleeding risk assessment, as well as new treatment options. An increasing awareness of AF has led to calls to improve the detection of and population screening for AF. Stroke and bleeding risk assessment continues to evolve, and the ongoing debate on balance between simplicity and practicality, against precision medicine will continue...

Pharmacotherapeutic options for pulmonary arterial hypertension (PAH) have increased dramatically in the last two decades and along with this have been substantial improvements in survival. Despite these advances, however, PAH remains a progressive and ultimately fatal disease for most patients and only epoprostenol has been shown to improve survival in a randomized control trial. Clinical observations of the heterogeneity of treatment response to different classes of medications across the phenotypically diverse PAH population has led to the identification of patients who derive significantly more benefit from certain medications than the population mean, the so-called "super responders...

Very Small Embryonic-Like cells (VSELs) are a population of very rare pluripotent stem cells isolated in adult murine bone marrow and many other tissues and organs, including umbilical cord blood. VSELs existence is still not universally accepted by the scientific community so, on this purpose, we sought to investigate whether presumptive VSELs (pVSELs) could be isolated from human umbilical cord blood with an improved protocol based on the isolation of enriched progenitor cells by depletion of non-progenitor cells with magnetic separation...

REVIEW
Thomas Bieber
Although atopic dermatitis (AD) is the most common skin disorder, there remains an ongoing debate on this denomination, its definition and the binary view based on immunoglobulin E measurement. The wide spectrum of the clinical phenotype of AD reflects the complex genetic and pathophysiologic mechanisms underlying the disease. The diagnostic criteria have to be reconsidered and adapted to different ethnic populations. There is an urgent need for biomarker discovery further supporting the clinical diagnostic criteria as well as the precision medicine approach on a global level...

Although there is no doubt about the scientific value of randomized controlled clinical trials, they are usually conducted in selected populations different from those treated in clinical practice. Therefore, it is important to optimize real-time post-marketing evaluation of effectiveness, safety, and cost of new drugs. Using electronic health records and administrative health databases from a well-defined region with universal access to healthcare, we have built a framework for real-time sequential monitoring of the effectiveness of newly marketed drugs in routine care...

David S Liebeskind
Precision cerebrovascular health or individualized long-term preservation of the brain and associated blood vessels, is predicated on understanding, diagnosing, and tailoring therapies for people at risk of ischemic injury associated with stroke and vascular dementia. The associated imaging patterns are sculpted by the protective effect of the collaterome, the innate compensatory ability of the brain and vasculature to offset hypoperfusion when antegrade or normal arterial inflow pathways are compromised. Theranostics or rational and synchronous use of diagnostic studies in tandem with specific therapies to optimally guide patient outcomes in ischemic brain disorders may capitalize on the pivotal role of the collaterome...
