Inconsistencies in the association of clinical factors with the choice of early steroid withdrawal across kidney transplant centers: A national registry study
BACKGROUND:Approximately 30% of kidney transplant recipients undergo early steroid withdrawal (ESW) for maintenance immunosuppression. However, there is no consensus on which patients are suitable for ESW, and transplant centers may disagree on how various clinical factors characterize individual recipients' suitability for ESW. METHODS:To examine center-level variation in the association of clinical factors with the choice of ESW, we studied 206Â 544 kidney transplant recipients from 278 centers in 2002-2017 using SRTR data. We conducted multi-level logistic regressions to characterize the association of clinical factors with the choice of ESW at each transplant center. RESULTS:). When estimated at each center, this odds ratio was significantly lower than the population odds ratio at 48 (17.3%) centers and significantly higher at 28 (10.1%) centers. CONCLUSIONS:We have observed apparent inconsistencies across transplant centers in the practice of tailoring ESW to the recipient's risk profile. Standardized guidelines for ESW tailoring are needed.

Early steroid withdrawal in HIV-infected kidney transplant recipients: Utilization and outcomes
Kidney transplant (KT) outcomes for HIV-infected (HIV+) persons are excellent, yet acute rejection (AR) is common and optimal immunosuppressive regimens remain unclear. Early steroid withdrawal (ESW) is associated with AR in other populations, but its utilization and impact are unknown in HIV+ KT. Using SRTR, we identified 1225 HIV+ KT recipients between January 1, 2000, and December 31, 2017, without AR, graft failure, or mortality during KT admission, and compared those with ESW with those with steroid continuation (SC). We quantified associations between ESW and AR using multivariable logistic regression and interval-censored survival analysis, as well as with graft failure and mortality using Cox regression, adjusting for donor, recipient, and immunologic factors. ESW utilization was 20.4%, with more zero HLA mismatch (8% vs 4%), living donors (26% vs 20%), and lymphodepleting induction (64% vs 46%) compared to the SC group. ESW utilization varied widely across 129 centers, with less use at high- versus moderate-volume centers (6% vs 21%, PÂ <Â .001). AR was more common with ESW by 1Â year (18.4% vs 12.3%; aOR: 1.08 1.612.41 , PÂ =Â .04) and over the study period (aHR: 1.02 1.391.90 , PÂ =Â .03), without difference in death-censored graft failure (aHR 0.60 0.911.36 , PÂ =Â .33) or mortality (aHR: 0.75 1.151.77 , PÂ =Â .45). To reduce AR after HIV+ KT, tailoring of ESW utilization is reasonable.

Development and Assessment of a Pictographic Pediatric Constipation Action Plan
OBJECTIVE:To assess the Uniformed Services Constipation Action Plan (USCAP) as an evidence-based, personalized, clinical action tool with pictograms to aid clinicians and families in the management of functional constipation. STUDY DESIGN/METHODS:The USCAP facilitates the management functional constipation by using a health literacy-informed approach to provide instructions for pharmacotherapies and lifestyle modifications. This study included part 1 (pictogram validation) and part 2 (assessment). For part 1, pictogram transparency, translucency, and recall were assessed by parent survey (transparency ≥85%, mean translucency score ≥5, recall ≥85% required for validation). For part 2, the USCAP was assessed by parents, clinical librarians, and clinicians. Parental perceptions (n = 65) were assessed using the Consumer Information Rating Form (17 questions) to gauge comprehensibility, design quality and usefulness. Readability was assessed by 5 formulas and a Readability Composite Score was calculated. Clinical librarians (n = 3) used the Patient Education Materials Assessment Tool to measure understandability (19 questions) and actionability (7 questions) (>80% rating was acceptable). Suitability was assessed by clinicians (n = 34) using Doak's Suitability Assessment of Materials (superior ≥70% rating). RESULTS:All 12 pictograms demonstrated appropriate transparency, translucency, and recall. Parental perceptions reflected appropriate comprehensibility, design quality, and usefulness. The Readability Composite Score was consistent with a fifth-grade level. Clinical librarians reported acceptable understandability and actionability. Clinicians reported superior suitability. CONCLUSIONS:The USCAP met all criteria for clinical implementation and future study of USCAP implementation for treating children with chronic functional constipation.

Fertility preservation for female patients with childhood, adolescent, and young adult cancer: recommendations from the PanCareLIFE Consortium and the International Late Effects of Childhood Cancer Guideline Harmonization Group
Female patients with childhood, adolescent, and young adult cancer are at increased risk for fertility impairment when treatment adversely affects the function of reproductive organs. Patients and their families desire biological children but substantial variations in clinical practice guidelines reduce consistent and timely implementation of effective interventions for fertility preservation across institutions. As part of the PanCareLIFE Consortium, and in collaboration with the International Late Effects of Childhood Cancer Guideline Harmonization Group, we reviewed the current literature and developed a clinical practice guideline for fertility preservation in female patients who were diagnosed with childhood, adolescent, and young adult cancer at age 25 years or younger, including guidance on risk assessment and available methods for fertility preservation. The Grading of Recommendations Assessment, Development and Evaluation methodology was used to grade the available evidence and to form the recommendations. This clinical practice guideline leverages existing evidence and international expertise to develop transparent recommendations that are easy to use to facilitate the care of female patients with childhood, adolescent, and young adult cancer who are at high risk for fertility impairment. A complete review of the existing evidence, including a quality assessment, transparent reporting of the guideline panel's decisions, and achievement of global interdisciplinary consensus, is an important result of this intensive collaboration.

Adiposity Measures and Morning Serum Cortisol in African Americans: Jackson Heart Study
OBJECTIVE:Altered hormonal regulation, including cortisol, is a proposed mechanism linking adiposity to obesity-related disorders. We examined the association of anthropometric, adipokine, and body fat distribution measures of adiposity with morning serum cortisol in an African American (AA) cohort. METHODS:We investigated the cross-sectional associations of adiposity measures (BMI, waist circumference, leptin, adiponectin, leptin:adiponectin ratio, subcutaneous and visceral adipose tissue) and liver attenuation with cortisol in the Jackson Heart Study. Linear regression models were used to analyze the association between exposures and cortisol. Models were adjusted for multiple covariates. RESULTS:Among 4,211 participants, a 1-SD higher BMI and waist circumference were associated with a 3.92% and 3.05% lower cortisol, respectively. A 1-SD higher leptin and leptin:adiponectin ratio were associated with a 6.48% and 4.97% lower morning serum cortisol, respectively. A 1-SD higher subcutaneous adipose tissue was associated with a 4.97% lower cortisol (all P < 0.001). There were no associations of liver attenuation or visceral adipose tissue with cortisol. CONCLUSIONS:Several measures of adiposity are associated with lower morning serum cortisol among AAs, with leptin having the greatest magnitude. Future studies examining the role of morning serum cortisol in the pathway from adiposity to cardiometabolic disease in AAs are warranted.

Implementation of Telemental Health (TMH) psychological services for rural veterans at the VA New York Harbor Healthcare System
Meeting the mental health needs of our current veteran population is one of the primary challenges facing the Veteran's Health Administration (VHA). Particularly for veterans residing in rural areas, the lack of providers, high provider turnover, and the burden of traveling long distances to VHA facilities may contribute to difficulties accessing mental health care. Telemental Health (TMH) services help bridge the geographic gap between mental health providers and veterans who need mental health services. The VHA TMH Hub initiative has attempted to leverage changes in technology-facilitated care by developing a model in which a facility "hub" could expand mental health resources to remote "spoke" clinics and veterans' residences. This paper describes the implementation of the VA New York Harbor Health care System (VA NYH) TMH Hub, which was one of 6 programs funded by the VHA Office of Rural Health (ORH) in September 2016. We will describe the structure of the program, services provided, veterans served, and our efforts to integrate quality improvement, research, and clinical training into the operations of the program.

The Effects of Four Doses of Vitamin D Supplements on Falls in Older Adults : A Response-Adaptive, Randomized Clinical Trial
BACKGROUND:Vitamin D supplementation may prevent falls in older persons, but evidence is inconsistent, possibly because of dosage differences. OBJECTIVE:supplements on falls. DESIGN:2-stage Bayesian, response-adaptive, randomized trial. (ClinicalTrials.gov: NCT02166333). SETTING:2 community-based research units. PARTICIPANTS:688 participants, aged 70 years and older, with elevated fall risk and a serum 25-hydroxyvitamin D [25-(OH)D] level of 25 to 72.5 nmol/L. INTERVENTION:doses, and the best noncontrol dose for preventing falls was determined. After dose finding, participants previously assigned to receive noncontrol doses received the best dose, and new enrollees were randomly assigned to receive 200 IU/d or the best dose. MEASUREMENTS:Time to first fall or death over 2 years (primary outcome). RESULTS: = 0.54). Analysis of falls with adverse outcomes suggested greater risk in the experience-with-best-dose group versus the 200-IU/d group (serious fall: HR, 1.87 [CI, 1.03 to 3.41]; fall with hospitalization: HR, 2.48 [CI, 1.13 to 5.46]). LIMITATIONS:per day, not a placebo. Dose finding ended before the prespecified thresholds for dose suspension and dose selection were reached. CONCLUSION:doses of 1000 IU/d or higher.

Subgroup Variation and Neighborhood Social Gradients-an Analysis of Hypertension and Diabetes Among Asian Patients (New York City, 2014-2017)
Diabetes and hypertension are socially patterned by individual race/ethnicity and by neighborhood economic context, but distributions among Asian subgroups are undercharacterized. We examined variation in prevalence for both conditions, comparing between US Asian subgroups, including within South Asian nationalities, and comparing within subgroups by neighborhood economic context. We obtained data on a non-probability sample of 633,664 patients ages 18-64 in New York City, NY, USA (2014-2017); 30,138 belonged to one of seven Asian subgroups (Asian Indian, Bangladeshi, Pakistani, Chinese, Korean, Japanese, and Filipino). We used electronic health records to classify disease status. We characterized census tract economic context using the Index of Concentration at the Extremes and estimated prevalence differences using multilevel models. Among Asian men, hypertension prevalence was highest for Filipinos. Among Asian women, hypertension prevalence was highest for Filipinas and Bangladeshis. Diabetes prevalence was highest among Pakistanis and Bangladeshis of both genders, exceeding all other Asian and non-Asian groups. There was consistent evidence of an economic gradient for both conditions, whereby persons residing in the most privileged neighborhood tertile had the lowest disease prevalence. The economic gradient was particularly strong for diabetes among Pakistanis, whose prevalence in the most deprived tertile exceeded that of the most privileged by 9 percentage points (95% CI 3, 14). Only Koreans departed from the trend, experiencing the highest diabetes prevalence in the most privileged tertile. US Asian subgroups largely demonstrate similar neighborhood economic gradients as other groups. Disaggregating Asian subgroups, including within South Asian nationalities, reveals important heterogeneity in prevalence.
