Clinical Long-Term Outcomes of Patient-Reported Outcomes in the Prospective Real-World Tofacitinib Response in Ulcerative Colitis Registry.

Introduction: We previously reported the results of tofacitinib induction therapy in the prospective multisite US real-world Tofacitinib Response in Ulcerative Colitis registry. We now assessed patient-reported outcomes (PROs) and predictors of success during tofacitinib maintenance therapy.

Methods: Tofacitinib Response in Ulcerative Colitis included 103 patients with refractory ulcerative colitis (UC); 67% had failed ≥ 2 biologics.

Tofacitinib Response in Ulcerative Colitis (TOUR): Early Response After Initiation of Tofacitinib Therapy in a Real-world Setting.

Background: Tofacitinib is an oral, small-molecule JAK inhibitor for the treatment of ulcerative colitis (UC). Using a novel electronic reporting tool, we aimed to prospectively describe the onset of tofacitinib efficacy during induction therapy in a real-world study.

Methods: Patient-reported outcome data (PROs) including the simple clinical colitis activity index (SCCAI), PRO Measurement Identification Systems (PROMIS) measures, and adverse events were collected daily for the first 14 days and at day 28 and 56.

Methotrexate Is Not Superior to Placebo in Maintaining Steroid-Free Response or Remission in Ulcerative Colitis.

Background & Aims: Parenteral methotrexate induces clinical remission but not endoscopic improvement of mucosal inflammation in patients with ulcerative colitis (UC). We performed a randomized, placebo-controlled trial to assess the efficacy of parenteral methotrexate in maintaining steroid-free response or remission in patients with UC after induction therapy with methotrexate and steroids.

Methods: We performed a 48-week trial, from February 2012 through May 2016, of 179 patients with active UC (Mayo score of 6-12 with endoscopy subscore ≥ 2) despite previous conventional or biological therapy.

Surrogate disease markers as substitutes for chronic disease outcomes in studies of diet and chronic disease relations.

Surrogate biomarkers for clinical outcomes afford scientific and economic efficiencies when investigating nutritional interventions in chronic diseases. However, valid scientific results are dependent on the qualification of these disease markers that are intended to be substitutes for a clinical outcome and to accurately predict benefit or harm. In this article, we examine the challenges of evaluating surrogate markers and describe the framework proposed in a 2010 Institute of Medicine report.

Options for basing Dietary Reference Intakes (DRIs) on chronic disease endpoints: report from a joint US-/Canadian-sponsored working group.

Dietary Reference Intakes (DRIs) are used in Canada and the United States in planning and assessing diets of apparently healthy individuals and population groups. The approaches used to establish DRIs on the basis of classical nutrient deficiencies and/or toxicities have worked well. However, it has proved to be more challenging to base DRI values on chronic disease endpoints; deviations from the traditional framework were often required, and in some cases, DRI values were not established for intakes that affected chronic disease outcomes despite evidence that supported a relation.

Inflammatory Bowel Disease: Epidemiology, Evaluation, Treatment, and Health Maintenance.

The incidence and prevalence of inflammatory bowel disease are rising. Crohn's disease and ulcerative colitis each have distinct features. Treatments are changing rapidly, and there are many new drugs in the pipeline.

The PhenX Toolkit: get the most from your measures.

The potential for genome-wide association studies to relate phenotypes to specific genetic variation is greatly increased when data can be combined or compared across multiple studies. To facilitate replication and validation across studies, RTI International (Research Triangle Park, North Carolina) and the National Human Genome Research Institute (Bethesda, Maryland) are collaborating on the consensus measures for Phenotypes and eXposures (PhenX) project. The goal of PhenX is to identify 15 high-priority, well-established, and broadly applicable measures for each of 21 research domains.

PhenX: a toolkit for interdisciplinary genetics research.

Purpose Of Review: To highlight standard PhenX (consensus measures for Phenotypes and eXposures) measures for nutrition, dietary supplements, and cardiovascular disease research and to demonstrate how these and other PhenX measures can be used to further interdisciplinary genetics research.

Recent Findings: PhenX addresses the need for standard measures in large-scale genomic research studies by providing investigators with high-priority, well established, low-burden measurement protocols in a web-based toolkit (https://www.phenxtoolkit.

Issues in the registration of clinical trials.

Public concerns about the perils associated with incomplete or delayed reporting of results from clinical trials has heightened interest in trial registries and results databases. Here we review the current status of trial registration efforts and the challenges in developing a comprehensive system of trial registration and reporting of results. ClinicalTrials.

Enrolling research subjects from clinical practice: ethical and procedural issues in the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial.

The Sequenced Treatment Alternatives to Relieve Depression (STAR*D) trial is a multi-site effectiveness study funded by the National Institute of Mental Health (NIMH) with the aim of identifying successful, acceptable and cost-effective treatment strategies for outpatients with unremitted depression. With enrollment of 4,041 adults with major depressive disorder (MDD), it is the largest controlled psychiatric treatment study ever undertaken. In the course of developing procedures to ensure that ambitious enrollment goals were met, a number of ethical and practical issues became apparent that underscore the conflicts between effectiveness research and human subject protections.

Development of the metabolic syndrome in black and white adolescent girls: a longitudinal assessment.

Background: The metabolic syndrome, associated with increased risk of type 2 diabetes mellitus and cardiovascular disease, begins to develop during adolescence.

Objective: We sought to identify early predictors of the presence of the syndrome at the ages of 18 and 19 years in black and white girls.

Methods: Using longitudinal data on participants from 2 centers in the National Heart, Lung, and Blood Institute Growth and Health Study, a 10-year cohort study, we applied cutoffs from the Adult Treatment Panel III to document changes in the prevalence of abnormal syndrome elements and the syndrome in girls aged 9 and 10 years, when cases were rare, and those aged 18 and 19 years, when prevalence had reached 3%.

Hyperforin plasma level as a marker of treatment adherence in the National Institutes of Health Hypericum Depression Trial.

Background: A previously reported clinical trial of Hypericum perforatum (St John's wort) in depression did not demonstrate efficacy. We assessed treatment adherence by measuring plasma hyperforin and evaluated the possible impact of adherence on study results.

Methods: Outpatients with major depression (N = 340) were randomized to an 8-week trial of H.

Obesity and the development of insulin resistance and impaired fasting glucose in black and white adolescent girls: a longitudinal study.

Objective: Age at onset of type 2 diabetes has decreased during the past 20 years, especially in black women. Studies of factors associated with insulin resistance and hyperglycemia in preadolescent and adolescent populations are essential to understanding diabetes development.

Research Design And Methods: The National Heart, Lung, and Blood Institute (NHLBI) Growth and Health Study (NGHS) is a 10-year cohort study of the development of obesity in black and white girls.

New opportunities and proven approaches in complementary and alternative medicine research at the National Institutes of Health.

This presentation describes some of the issues that arise when applying the clinical-trial approach of conventional medicine to complementary and alternative medicine (CAM) modalities. Conventional medicine has been making the evolution to using an evidence base and to making recommendations only when the evidence is strong. The National Center for Complementary Medicine (NCCAM), one of twenty-five Institutes or Centers of the National Institutes of Health (NIH), is working to hold CAM to the same high standards, not by rejecting previous CAM research, but by building on that strong evidence base of what works and what is safe.

Research on complementary and alternative medicine using randomized controlled trials.

In 1998, the National Institutes of Health (NIH) formed the National Center for Complementary and Alternative Medicine (NCCAM) from what had formerly been the Office of Alternative Medicine. This presentation opens with a brief discussion on the history of the NIH and the development of CAM at the NIH before moving on to the work of the NCCAM. The NCCAM is moving toward an integration of CAM therapies into conventional medicine, when there is evidence for the value of CAM.

Prevention research at the National Institutes of Health.

Prevention of disease and disability and preservation of health are compelling strategies that are endorsed by the public, health care providers, and researchers. Despite this general acceptance of the concept, the "devil is in the details." What can and should be recommended with confidence to the public and health care providers regarding prevention and how can these recommendations be implemented? Prevention programs should be based on durable evidence of efficacy and should assure that the benefits of interventions and changes exceed the risks.
