The Role of the Athletic Trainer in Providing Care to Transgender and Gender-Diverse Patients: Foundational Knowledge and Disparities-Part I.

Transgender and gender-diverse (TGD) patients experience discrimination, harassment, marginalization, and minority stress at greater rates than their cisgender counterparts, leading to numerous health and health care disparities that negatively affect well-being and access to quality health care.1 Despite being in an opportune position to improve health equity for TGD patients under their care, many athletic trainers (ATs) report having little to no formal education on TGD patient care, leading to a reduction in self-reported competence. As such, to fill this knowledge gap, the purposes of the first part of this 2-part narrative literature review are to (1) provide readers with foundational information and terminology, (2) explore relevant health and health care disparities, and (3) identify the role of the AT within an interprofessional care team treating TGD patients.

The Role of the Athletic Trainer in Providing Care to Transgender and Gender-Diverse Patients: Considerations for Medical Affirmation-Part II.

Recently, with discriminatory legislation efforts and changing participation policies in organized sports, media attention surrounding transgender and gender-diverse (TGD) individuals has increased. These changes and the historical lack of competence and education regarding the transgender patient population have resulted in subpar patient care and a misunderstanding of the athletic trainer's (AT's) role within the health care and compliance systems. This literature review is the second part of a 2-paper series, and our objective was to educate ATs on the processes relevant to medical affirmation, including compliance considerations regarding medical eligibility, and to establish the AT's role.

Comparative Safety and Effectiveness of Roux-en-Y Gastric Bypass and Sleeve Gastrectomy for Weight Loss and Type 2 Diabetes Across Race and Ethnicity in the PCORnet Bariatric Study Cohort.

Importance: Bariatric surgery is the most effective treatment for severe obesity; yet it is unclear whether the long-term safety and comparative effectiveness of these operations differ across racial and ethnic groups.

Objective: To compare outcomes of Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (SG) across racial and ethnic groups in the National Patient-Centered Clinical Research Network (PCORnet) Bariatric Study.

Design, Setting, And Participants: This was a retrospective, observational, comparative effectiveness cohort study that comprised 25 health care systems in the PCORnet Bariatric Study.

U.S. national water and energy land dataset for integrated multisector dynamics research.

Understanding resource demands and tradeoffs among energy, water, and land socioeconomic sectors requires an explicit consideration of spatial scale. However, incorporation of land dynamics within the energy-water nexus has been limited due inconsistent spatial units of observation from disparate data sources. Herein we describe the development of a National Water and Energy Land Dataset (NWELD) for the conterminous United States.

Preoperative Depression Status and 5 Year Metabolic and Bariatric Surgery Outcomes in the PCORnet Bariatric Study Cohort.

Objective: To examine whether depression status before metabolic and bariatric surgery (MBS) influenced 5-year weight loss, diabetes, and safety/utilization outcomes in the PCORnet Bariatric Study.

Summary Of Background Data: Research on the impact of depression on MBS outcomes is inconsistent with few large, long-term studies.

Methods: Data were extracted from 23 health systems on 36,871 patients who underwent sleeve gastrectomy (SG; n=16,158) or gastric bypass (RYGB; n=20,713) from 2005-2015.

Antibiotics prior to age 2 years have limited association with preschool growth trajectory.

Background: Prior studies of early antibiotic use and growth have shown mixed results, primarily on cross-sectional outcomes. This study examined the effect of oral antibiotics before age 24 months on growth trajectory at age 2-5 years.

Methods: We captured oral antibiotic prescriptions and anthropometrics from electronic health records through PCORnet, for children with ≥1 height and weight at 0-12 months of age, ≥1 at 12-30 months, and ≥2 between 25 and 72 months.

Early Life Antibiotic Prescriptions and Weight Outcomes in Children 10 Years of Age.

Objective: We previously found that antibiotic use at <24 months of age was associated with slightly higher body weight at 5 years of age. In this study, we examine associations of early life antibiotic prescriptions with weight outcomes at 108 to 132 months of age ("10 years").

Methods: We used electronic health record data from 2009 through 2016 from 10 health systems in PCORnet, a national distributed clinical research network.

Comparing the 5-Year Diabetes Outcomes of Sleeve Gastrectomy and Gastric Bypass: The National Patient-Centered Clinical Research Network (PCORNet) Bariatric Study.

Importance: Bariatric surgery can lead to substantial improvements in type 2 diabetes (T2DM), but outcomes vary across procedures and populations. It is unclear which bariatric procedure has the most benefits for patients with T2DM.

Objective: To evaluate associations of bariatric surgery with T2DM outcomes.

Interventions and Operations 5 Years After Bariatric Surgery in a Cohort From the US National Patient-Centered Clinical Research Network Bariatric Study.

Importance: Additional data comparing longer-term problems associated with various bariatric surgical procedures are needed for shared decision-making.

Objective: To compare the risks of intervention, operation, endoscopy, hospitalization, and mortality up to 5 years after 2 bariatric surgical procedures.

Design, Setting, And Participants: Adults who underwent Roux-en-Y gastric bypass (RYGB) or sleeve gastrectomy (SG) between January 1, 2005, and September 30, 2015, within the National Patient-Centered Clinical Research Network.

Privacy-protecting multivariable-adjusted distributed regression analysis for multi-center pediatric study.

Background: Privacy-protecting analytic approaches without centralized pooling of individual-level data, such as distributed regression, are particularly important for vulnerable populations, such as children, but these methods have not yet been tested in multi-center pediatric studies.

Methods: Using the electronic health data from 34 healthcare institutions in the National Patient-Centered Clinical Research Network (PCORnet), we fit 12 multivariable-adjusted linear regression models to assess the associations of antibiotic use <24 months of age with body mass index z-score at 48 to <72 months of age. We ran these models using pooled individual-level data and conventional multivariable-adjusted regression (reference method), as well as using the more privacy-protecting pooled summary-level intermediate statistics and distributed regression technique.

Comparing Prescribing and Dispensing Data of the PCORnet Common Data Model Within PCORnet Antibiotics and Childhood Growth Study.

Researchers often use prescribing data from electronic health records (EHR) or dispensing data from medication or medical claims to determine medication utilization. However, neither source has complete information on medication use. We compared antibiotic prescribing and dispensing records for 200,395 patients in the National Patient-Centered Clinical Research Network (PCORnet) Antibiotics and Childhood Growth Study.

Combining distributed regression and propensity scores: a doubly privacy-protecting analytic method for multicenter research.

Purpose: Sharing of detailed individual-level data continues to pose challenges in multi-center studies. This issue can be addressed in part by using analytic methods that require only summary-level information to perform the desired multivariable-adjusted analysis. We examined the feasibility and empirical validity of 1) conducting multivariable-adjusted distributed linear regression and 2) combining distributed linear regression with propensity scores, in a large distributed data network.

Comparative Effectiveness and Safety of Bariatric Procedures for Weight Loss: A PCORnet Cohort Study.

Background: There has been a dramatic shift in use of bariatric procedures, but little is known about their long-term comparative effectiveness.

Objective: To compare weight loss and safety among bariatric procedures.

Design: Retrospective observational cohort study, January 2005 to September 2015.

Comparative effectiveness of bariatric procedures among adolescents: the PCORnet bariatric study.

Background: Bariatric surgery has been used for treatment of severe obesity in adolescents but most studies have been small and limited in follow-up.

Objectives: We hypothesized that electronic health record data could be used to compare effectiveness of bariatric procedures in adolescents.

Setting: Data were obtained from clinical research networks using a common data model to extract data from each site.

Near Real-time Surveillance for Consequences of Health Policies Using Sequential Analysis.

Background: New health policies may have intended and unintended consequences. Active surveillance of population-level data may provide initial signals of policy effects for further rigorous evaluation soon after policy implementation.

Objective: This study evaluated the utility of sequential analysis for prospectively assessing signals of health policy impacts.

PCORnet Antibiotics and Childhood Growth Study: Process for Cohort Creation and Cohort Description.

Objectives: The National Patient-Centered Clinical Research Network (PCORnet) supports observational and clinical research using health care data. The PCORnet Antibiotics and Childhood Growth Study is one of PCORnet's inaugural observational studies. We sought to describe the processes used to integrate and analyze data from children across 35 participating institutions, the cohort characteristics, and prevalence of antibiotic use.

The National Patient-Centered Clinical Research Network (PCORnet) Bariatric Study Cohort: Rationale, Methods, and Baseline Characteristics.

Background: Although bariatric procedures are commonly performed in clinical practice, long-term data on the comparative effectiveness and safety of different procedures on sustained weight loss, comorbidities, and adverse effects are limited, especially in important patient subgroups (eg, individuals with diabetes, older patients, adolescents, and minority patients).

Objective: The objective of this study was to create a population-based cohort of patients who underwent 3 commonly performed bariatric procedures-adjustable gastric band (AGB), Roux-en-Y gastric bypass (RYGB), and sleeve gastrectomy (SG)-to examine the long-term comparative effectiveness and safety of these procedures in both adults and adolescents.

Methods: We identified adults (20 to 79 years old) and adolescents (12 to 19 years old) who underwent a primary (first observed) AGB, RYGB, or SG procedure between January 1, 2005 and September 30, 2015 from 42 health systems participating in the Clinical Data Research Networks within the National Patient-Centered Clinical Research Network (PCORnet).

Effect of body surface decolonisation on bacteriuria and candiduria in intensive care units: an analysis of a cluster-randomised trial.

Background: Urinary tract infections (UTIs) are common health-care-associated infections. Bacteriuria commonly precedes UTI and is often treated with antibiotics, particularly in hospital intensive care units (ICUs). In 2013, a cluster-randomised trial (REDUCE MRSA Trial [Randomized Evaluation of Decolonization vs Universal Clearance to Eradicate MRSA]) showed that body surface decolonisation reduced all-pathogen bloodstream infections.

Rationale and design of the oral HEMe iron polypeptide Against Treatment with Oral Controlled Release Iron Tablets trial for the correction of anaemia in peritoneal dialysis patients (HEMATOCRIT trial).

Background: The main hypothesis of this study is that oral heme iron polypeptide (HIP; Proferrin ES) administration will more effectively augment iron stores in erythropoietic stimulatory agent (ESA)-treated peritoneal dialysis (PD) patients than conventional oral iron supplementation (Ferrogradumet).

Methods: Inclusion criteria are peritoneal dialysis patients treated with darbepoietin alpha (DPO; Aranesp(R), Amgen) for >or= 1 month. Patients will be randomized 1:1 to receive either slow-release ferrous sulphate (1 tablet twice daily; control) or HIP (1 tablet twice daily) for a period of 6 months.

Off-label use of rituximab in a tertiary Queensland hospital.

Background: Rituximab is a monoclonal antibody directed against CD20, a pan B lymphocyte marker. It is approved in Australia for treatment of CD20-positive B cell non-Hodgkin lymphoma and rheumatoid arthritis. There is increasing off-label use of rituximab in conditions where B cells and autoantibodies play a role in the pathophysiology.
