OBJECTIVE: A primary objective of the Healthy People 2010 initiatives is to increase on-time immunization rates during the first 2 years of life and to decrease racial disparities in coverage. The objective of this study was to determine on-time immunization coverage rates among infants and toddlers stratified by race/ethnicity in a large metropolitan center. METHODS: A retrospective cohort study that was based on immunization records in the Chicago Public Schools computerized database was conducted using all 67376 children who completed kindergarten in 2001 and 2002. RESULTS: On-time immunization rates in Chicago public school children are low (31% at 7 months, 32% at 19 months, 59% at 36 months). At 19 months of age and thereafter, Hispanic children had the highest rate of on-time immunization coverage. Among children <48 months old, black children had the lowest rates of up-to-date immunization status. At 48 months of age, the up-to-date rate for black children improved to a rate similar to white children (58%) and by school entry surpassed the up-to-date rate for white children (71%). Compared with the recommended 2, 4, 6, and 15 to 18 months schedule, black children received 4 doses of diphtheria/tetanus/acellular pertussis at a mean age of 10.0, 14.6, 20.4, and 34.5 months of age. In contrast, Hispanic children received the same doses at a mean of 4.5, 7.4, 11.0, and 25.1 month of age. In addition, approximately 25% of black children received the majority of their vaccinations >12 months later than the recommended time intervals. CONCLUSIONS: Striking immunization delay still exists during the infant and toddler years. Targeted efforts are needed to increase on-time immunization rates and to decrease racial disparity in immunization coverage. [ABSTRACT FROM AUTHOR]

Background: Clinical practice recommendations for macronutrient intake in Metabolic and Bariatric Surgery (MBS) are insufficiently grounded in the research, possibly due to a paucity of research in key areas necessary to support macronutrient recommendations. An initial scoping review, prior to any systematic review, was determined to be vital., Objectives: To identify topical areas in macronutrients and MBS with a sufficient evidence base to guide nutrition recommendations., Methods: PubMed, Cochrane, Ovid Medline, and Embase were initially searched in January 2019 (updated November 1, 2023) with terms encompassing current bariatric surgeries and macronutrients. Out of 757 records identified, 98 were included. A template was created. Five types of outcomes were identified for extraction: dietary intake, anthropometrics, adverse symptoms, health, and metabolic outcomes. All stages of screening and extraction were conducted independently by at least two authors and disagreements were resolved via team discussion. Macronutrient-related dietary treatments were classified as either innovative or standard of care. Descriptions of dietary arms were extracted in detail for a qualitatively generated typology of dietary or nutritional treatments. Heatmaps (treatments by outcomes) were produced to identify promising topics for further systematic analyses., Results: We identified protein supplementation and "food-focused" (e.g., portion-controlled meals, particular foods in the diet, etc.) topical areas in MBS nutrition care with potentially sufficient evidence to create specific MBS Macronutrients guidelines and identified topical areas with little research., Conclusions: Clinical practice regarding macronutrient intake remains guided by consensus and indirect evidence. We detail ways that leadership at the profession level may remedy this., (© 2024 The Author(s). Obesity Reviews published by John Wiley & Sons Ltd on behalf of World Obesity Federation.)

SUMMARYBlood cultures (BCs) are one of the critical tests used to detect bloodstream infections. BC results are not 100% specific. Interpretation of BC results is often complicated by detecting microbial contamination rather than true infection. False positives due to blood culture contamination (BCC) vary from 1% to as high as >10% of all BC results. False-positive BC results may result in patients undergoing unnecessary antimicrobial treatments, increased healthcare costs, and delay in detecting the true cause of infection or other non-infectious illness. Previous guidelines from the Clinical and Laboratory Standards Institute, College of American Pathologists, and others, based on expert opinion and surveys, promoted a limit of ≤3% as acceptable for BCC rates. However, the data supporting such recommendations are controversial. A previous systematic review of BCC examined three practices for reducing BCC rates (venipuncture, phlebotomy teams, and pre-packaged kits). Subsequently, numerous studies on different practices including using diversion devices, disinfectants, and education/training to lower BCC have been published. The goal of the current guideline is to identify beneficial intervention strategies to reduce BCC rates, including devices, practices, and education/training by providers in collaboration with the laboratory. We performed a systematic review of the literature between 2017 and 2022 using numerous databases. Of the 11,319 unique records identified, 311 articles were sought for full-text review, of which 177 were reviewed; 126 of the full-text articles were excluded based on pre-defined inclusion and exclusion criteria. Data were extracted from a total of 49 articles included in the final analysis. An evidenced-based committee's expert panel reviewed all the references as mentioned in Data Collection and determined if the articles met the inclusion criteria. Data from extractions were captured within an extraction template in the US Agency for Healthcare Research and Quality's Systematic Review Data Repository (https://srdr.ahrq.gov/). BCC rates were captured as the number of events (contaminated samples) per arm (standard practice versus improvement practice). Modified versions of the National Heart, Lung, and Blood Institute Study Quality Assessment Tools were used for risk of bias assessment (https://www.nhlbi.nih.gov/health-topics/study-quality-assessment-tools). We used Grading of Recommendations, Assessment, Development and Evaluations to assess strength of evidence. There are several interventions that resulted in significant reduction in BCC rates: chlorhexidine as a disinfectant for skin preparation, using a diversion device prior to drawing BCs, using sterile technique practices, using a phlebotomy team to obtain BCs, and education/training programs. While there were no substantial differences between methods of decreasing BCC, our results indicate that the method of implementation can determine the success or failure of the intervention. Our evidence-based systematic review and meta-analysis support several interventions to effectively reduce BCC by approximately 40%-60%. However, devices alone without an education/training component and buy-in from key stakeholders to implement various interventions would not be as effective in reducing BCC rates.

SUMMARYClinical medicine has embraced the use of evidence for patient treatment decisions; however, the evaluation strategy for evidence in laboratory medicine practices has lagged. It was not until the end of the 20th century that the Institute of Medicine (IOM), now the National Academy of Medicine, and the Centers for Disease Control and Prevention, Division of Laboratory Systems (CDC DLS), focused on laboratory tests and how testing processes can be designed to benefit patient care. In collaboration with CDC DLS, the American Society for Microbiology (ASM) used an evidence review method developed by the CDC DLS to develop a program for creating laboratory testing guidelines and practices. The CDC DLS method is called the Laboratory Medicine Best Practices (LMBP) initiative and uses the A-6 cycle method. Adaptations made by ASM are called Evidence-based Laboratory Medicine Practice Guidelines (EBLMPG). This review details how the ASM Systematic Review (SR) Processes were developed and executed collaboratively with CDC's DLS. The review also describes the ASM transition from LMBP to the organization's current EBLMPG, maintaining a commitment to working with agencies in the U.S. Department of Health and Human Services and other partners to ensure that EBLMPG evidence is readily understood and consistently used.

Introduction: Persons with non-ambulatory spinal cord injury (SCI) undergo immediate unloading of the skeleton and, as a result, have marked loss of bone mineral density below the level of lesion that is directly associated with increased risk of long-bone fractures. There is a paucity of research that has successfully implemented rehabilitation and/or exercise training interventions to mitigate bone loss after acute SCI or reverse bone loss that has already occurred in chronic SCI. This paper describes a research protocol to compare the effect of exoskeletal-assisted walking (EAW) alone versus EAW plus transcutaneous spinal cord stimulation (EAW+tSCS) on bone density, geometry and strength in a cohort of chronic SCI participants., Methods and Analysis: After meeting eligibility criteria and completing baseline testing, sixteen participants will be block randomised into the EAW alone group or the EAW+tSCS combined group (n=8 each group). Each group will receive a total of 108 overground training sessions (60 min sessions, 3 times a week, for 36 weeks) for the 9-month training period. Imaging for bone density and geometry by dual-energy X-ray absorptiometry and peripheral quantitative CT will be performed prior to starting the intervention (baseline), after 72 training sessions, and again after 108 sessions in each of the intervention arms. CT imaging of both lower extremities will be performed at baseline and at the 9-month time point in each of the intervention arms. Finite element models of bone loading will be generated based on three-dimensional (3D) reconstruction of bone architecture from CT imaging prior to and 9 months after the intervention., Ethics and Dissemination: This study is currently approved by the Kessler Foundation and James J. Peters VA Medical Center Institutional Review Board. A member of the research team will review and explain the study consent form and will have all eligible participants sign prior to participation in the study. Results from this study will be disseminated to clinicians and researchers in the SCI community at national and international conferences., Trial Registration Number: NCT03096197., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Introduction: Vitamin B1 (thiamine) deficiency (TD) after metabolic and bariatric surgery (MBS) is often insidious and, if unrecognized, can lead to irreversible damage or death. As TD symptoms are vague and overlap with other disorders, we aim to identify predictors of recurrent TD and failure to collect B1 labs., Methods: We analyzed a large sample of data from patients with MBS ( n = 878) to identify potential predictors of TD risk. We modeled recurrent TD and failure to collect B1 labs using classical statistical and machine learning (ML) techniques., Results: We identified clusters of labs associated with increased risk of recurrent TD: micronutrient deficiencies, abnormal blood indices, malnutrition, and fluctuating electrolyte levels (aIRR range: 1.62-4.68). Additionally, demographic variables associated with lower socioeconomic status were predictive of recurrent TD. ML models predicting characteristics associated with failure to collect B1 labs achieved 75-81% accuracy, indicating that clinicians may fail to match symptoms with the underlying condition., Conclusions: Our analysis suggests that both clinical and social factors can increase the risk of life-threatening TD episodes in some MBS patients. Identifying these indicators can help with diagnosis and treatment.

Background and Objectives: Traumatic brain injury (TBI) is a concern for US service members and veterans (SMV), leading to heterogeneous psychological and cognitive outcomes. We sought to identify neuropsychological profiles of mild TBI (mTBI) and posttraumatic stress disorder (PTSD) among the largest SMV sample to date., Methods: We analyzed cross-sectional baseline data from SMV with prior combat deployments enrolled in the ongoing Long-term Impact of Military-relevant Brain Injury Consortium-Chronic Effects of Neurotrauma Consortium prospective longitudinal study. Latent profile analysis identified symptom profiles using 35 indicators, including physical symptoms, depression, quality of life, sleep quality, postconcussive symptoms, and cognitive performance. It is important to note that the profiles were determined independently of mTBI and probable PTSD status. After profile identification, we examined associations between demographic variables, mTBI characteristics, and PTSD symptoms with symptom profile membership., Results: The analytic sample included 1,659 SMV (mean age 41.1 ± 10.0 years; 87% male); among them 29% (n = 480) had a history of non-deployment-related mTBI only, 14% (n = 239) had deployment-related mTBI only, 36% (n = 602) had both non-deployment and deployment-related mTBI, and 30% (n = 497) met criteria for probable PTSD. A 6-profile model had the best fit, with separation on all indicators ( p < 0.001). The model revealed distinct neuropsychological profiles, representing a combination of 3 self-reported functioning patterns: high (HS), moderate (MS), and low (LS), and 2 cognitive performance patterns: high (HC) and low (LC). The profiles were (1) HS/HC: n=301, 18.1%; (2) HS/LC: n=294, 17.7%; (3) MS/HC: n=359, 21.6%; (4) MS/LC: n=316, 19.0%; (5) LS/HC: n=228, 13.7%; and (6) LS/LC: n=161, 9.7%. SMV with deployment-related mTBI tended to be grouped into lower functioning profiles and were more likely to meet criteria for probable PTSD. Conversely, SMV with no mTBI exposure or non-deployment-related mTBI were clustered in higher functioning profiles and had a lower likelihood of meeting criteria for probable PTSD., Discussion: Findings suggest varied symptom and functional profiles in SMV, influenced by injury context and probable PTSD comorbidity. Despite diagnostic challenges, comprehensive assessment of functioning and cognition can detect subtle differences related to mTBI and PTSD, revealing distinct neuropsychological profiles. Prioritizing early treatment based on these profiles may improve prognostication and support efficient recovery.

Objective: To investigate the effects of a high frequency strengthening program on function, pain, and pain sensitization in female runners with chronic patellofemoral pain (PFP)., Design: Cross-sectional study., Setting: University laboratory., Participants: Thirty female runners (mean age 32 ± 8.1 years) with chronic PFP completed an 8-week home strengthening program., Main Outcome Measures: Variables assessed at baseline, 8-weeks, and 12 weeks included single leg step down test (SLSD), pain, Anterior Knee Pain Scale (AKPS), University of Wisconsin Running Injury and Recovery Index (UWRI), and quantitative sensory testing., Results: There was large and statistically significant improvement at 8 and 12 weeks for average knee pain (η p 2  = 0.334, p < 0.001), worst knee pain (η p 2  = 0.351, p < 0.001), SLSD (η p 2  = 0.161, p = 0.001), AKPS (η p 2  = 0.463, p < 0.001), and UWRI (η p 2  = 0.366, p < 0.001). A medium to large effect and statistically significant improvement in pressure pain threshold testing was found for all local and remote structures (η p 2 range, 0.110 to 0.293, range p < 0.001 to p = 0.009) at 8 and 12 weeks., Conclusions: There was a significant decrease in local and remote hyperalgesia via mechanical and thermal pain sensitivity testing in female runners with chronic PFP. There was a large effect and significant improvement in self-reported pain and function., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Objective: The purpose of this study was to describe the relationship between behavioral and psychological traits with indicators of central sensitization in female runners with patellofemoral pain (PFP), and to determine if behavioral and psychological traits improve with strength training., Design: Cross-sectional study., Setting: University laboratory., Participants: Twenty-eight active females (mean age 32 ± 8.1 years) with PFP completed testing at baseline, 8 weeks (post intervention), and 12 weeks., Main Outcome Measures: Behavioral and psychological questionnaires included the General Anxiety Disorder-7, Patient Health Questionairre-9, Pain Catastrophizing Scale, Tampa Scale of Kinesiophobia-11, and Central Sensitization Inventory. Quantitative sensory testing (QST) measures were also collected. After baseline testing, subjects were instructed in a hip and knee strengthening intervention to be completed twice daily over 8 weeks., Results: A statistically significant improvement was found at 12 weeks for anxiety (p = .015; ηp (Boling et al., 2010) = 0.099) and kinesiophobia (p = .041; ηp (Boling et al., 2010) = 0.076). There was no significant improvement for depression, catastrophizing, or subjective central sensitization. No significant correlations were found between any of the behavioral and psychological questionnaires with baseline QST variables., Conclusions: No relationship was found for behavioral and psychological characteristics with QST measures in female runners with persistent PFP., Competing Interests: Declaration of competing interest None., (Copyright © 2024 Elsevier Ltd.

Heterogeneous response to Enzalutamide, a second-generation androgen receptor signaling inhibitor, is a central problem in castration-resistant prostate cancer (CRPC) management. Genome-wide systems investigation of mechanisms that govern Enzalutamide resistance promise to elucidate markers of heterogeneous treatment response and salvage therapies for CRPC patients. Focusing on the de novo role of MYC as a marker of Enzalutamide resistance, here we reconstruct a CRPC-specific mechanism-centric regulatory network, connecting molecular pathways with their upstream transcriptional regulatory programs. Mining this network with signatures of Enzalutamide response identifies NME2 as an upstream regulatory partner of MYC in CRPC and demonstrates that NME2-MYC increased activities can predict patients at risk of resistance to Enzalutamide, independent of co-variates. Furthermore, our experimental investigations demonstrate that targeting MYC and its partner NME2 is beneficial in Enzalutamide-resistant conditions and could provide an effective strategy for patients at risk of Enzalutamide resistance and/or for patients who failed Enzalutamide treatment., (© 2024.

Objective: Mild traumatic brain injury (mTBI) and posttraumatic stress disorder (PTSD) commonly occur among military Service Members and Veterans and have heterogenous, but also overlapping symptom presentations, which often complicate the diagnoses of underlying impairments and development of effective treatment plans. Thus, we sought to examine whether the combination of whole brain gray matter (GM) and white matter (WM) structural measures with neuropsychological performance can aid in the classification of military personnel with mTBI and PTSD., Methods: Active-Duty US Service Members ( n = 156; 87.8% male) with a history of mTBI, PTSD, combined mTBI+PTSD, or orthopedic injury completed a neuropsychological battery and T1- and diffusion-weighted structural neuroimaging. Cortical, subcortical, ventricular, and WM volumes and whole brain fractional anisotropy (FA), mean diffusivity (MD), radial diffusivity (RD), and axial diffusivity (AD) were calculated. Latent profile analyses were performed to determine how the GM and WM indicators, together with neuropsychological indicators, classified individuals., Results: For both GM and WM, respectively, a 4-profile model was the best fit. The GM model identified greater ventricular volumes in Service Members with cognitive symptoms, including those with a diagnosis of mTBI, either alone or with PTSD. The WM model identified reduced FA and elevated RD in those with psychological symptoms, including those with PTSD or mTBI and comorbid PTSD. However, contrary to expectation, a global neural signature unique to those with comorbid mTBI and PTSD was not identified., Conclusions: The findings demonstrate that neuropsychological performance alone is more robust in differentiating Active-Duty Service Members with mTBI and PTSD, whereas global neuroimaging measures do not reliably differentiate between these groups., Competing Interests: The authors declare no conflicts of interests., (Copyright © 2022 Wolters Kluwer Health, Inc.

Purpose: Vitamin C (VC) is implicated in many physiological pathways. Vitamin C deficiency (VCD) can compromise the health of patients with metabolic and bariatric surgery (patients). As symptoms of VCD are elusive and data on VCD in patients is scarce, we aim to characterize patients with measured VC levels, investigate the association of VCD with other lab abnormalities, and create predictive models of VCD using machine learning (ML)., Methods: A retrospective chart review of patients seen from 2017 to 2021 at a tertiary care center in Northeastern USA was conducted. A 1:4 case mix of patients with VC measured to a random sample of patients without VC measured was created for comparative purposes. ML models (BayesNet and random forest) were used to create predictive models and estimate the prevalence of VCD patients., Results: Of 5946 patients reviewed, 187 (3.1%) had VC measures, and 73 (39%) of these patients had VC<23 μmol/L(VCD. When comparing patients with VCD to patients without VCD, the ML algorithms identified a higher risk of VCD in patients deficient in vitamin B1, D, calcium, potassium, iron, and blood indices. ML models reached 70% accuracy. Applied to the testing sample, a "true" VCD prevalence of ~20% was predicted, among whom ~33% had scurvy levels (VC<11 μmol/L)., Conclusion: Our models suggest a much higher level of patients have VCD than is reflected in the literature. This indicates a high proportion of patients remain potentially undiagnosed for VCD and are thus at risk for postoperative morbidity and mortality., (© 2023.

Twelve months following discontinuation of denosumab, the percent decrease in mean bone mineral density (BMD) values at the hip and knee regions were similar between both the denosumab and placebo groups. These findings emphasize the need for additional trials to understand the effect of continued administration of denosumab after subacute spinal cord injury (SCI) to avoid this demineralization., Objective: To determine changes in BMD 1 year after denosumab was discontinued in participants with subacute SCI who had drug treatment initiated within 90 days post SCI and continued for 1 year., Methods: Fourteen participants who completed a randomized, double-blinded, placebo-controlled drug trial (parent study: denosumab 60 mg (Prolia, Amgen Inc., n = 8) or placebo (n = 6); administered at baseline, 6, and 12 months) were followed 12 months after the 18 months from baseline primary end point was completed. The BMD of skeletal regions below the SCI at higher risk of fracture was measured [total hip, distal femur epiphysis (DFE), distal femur metaphysis (DFM), and proximal tibia epiphysis (PTE)] by dual energy X-ray absorptiometry., Results: The percent decreases in mean BMD values at all regions of the hip and knee from 18 to 30 months were similar in both the denosumab and placebo groups. However, at 30 months, the absolute values for mean BMD remained significantly higher in the drug treatment than that of the placebo group at the DFM (p = 0.03), DFE (p = 0.04), and PTE (p = 0.05)., Conclusions: In persons with SCI who initiated denosumab treatment during the subacute injury phase and maintained treatment for 1 year, the discontinuation of drug resulted in percent loss of mean BMD similar to that of the placebo group, with absolute mean BMD values at the knee regions at the 12-month follow-up visit significantly higher in the drug treatment than those in the placebo group. These data underscore the need to study continued administration of denosumab after subacute SCI to avoid marked demineralization in the sublesional skeleton upon discontinuation of this agent., (© 2023.

Objective: Individuals with end-stage kidney disease (ESKD) receiving maintenance hemodialysis (MHD) are at risk for protein-energy wasting (PEW). Inadequate dietary intake and altered anthropometrics are two criteria of the PEW diagnosis. This study explored whether individuals with ESKD on MHD meet the National Kidney Foundation Kidney Disease Outcome Quality Initiative (NKF-KDOQI) 2020 guidelines for nutritional adequacy on a dialysis treatment day (DD) and explored the relationship between dietary energy [DEI] and protein [DPI] intake and anthropometrics., Methods: This was a secondary analysis of clinical and demographic data for 142 adults from the Rutgers Nutrition and Kidney Disease database. The study assessed the relationships between DEI, DPI, and anthropometrics, including body mass index (BMI), BMI category, waist circumference, and waist-to-hip ratio (WHR) using Pearson's or Spearman's correlation and one-way ANOVA., Results: The sample had a median age of 55.7 years; 58% were male, 83.8% were Black/African American, with a median dialysis vintage of 42.0 months (e.g., 3.5 years). Seventy-five percent of the data sample were overweight or obese. The WHR was 1.0 ± 0.8 cm for males and 0.9 ± 0.1 for females. DEI and DPI on a DD did not meet the NKF-KDOQI 2020 guidelines. Median DEI was 17.6 ± 8.4 kcal/kg and DPI was 0.7 ± 0.4 g/kg. In the total sample, significant positive correlations were found between DEI (r = 0.74, P = 0.03) and DPI (r = 0.18, P = 0.037) and WHR. In females, a significant positive correlation was identified between DPI and WHR (r = 0.26, P = 0.046)., Conclusions: These findings suggest that the nutritional intake of individuals with ESKD receiving MHD is inadequate to meet NKF-KDOQI 2020 guidelines on a DD. WHR may be a useful tool to assess alterations in anthropometrics related to DEI or DPI in this population, but more research is warranted., (Copyright © 2022 National Kidney Foundation, Inc.

Background: Patellofemoral pain (PFP) is a common overuse injury among runners, affecting females at a higher rate than males. PFP can often become chronic, with evidence suggesting it may be linked to both peripheral and central sensitization of the nervous system. Sensitization of the nervous system can be identified through quantitative sensory testing (QST)., Hypothesis/purpose: The primary objective of this pilot study was to quantify and compare pain sensitivity as identified through QST measures, in active female runners with and without PFP., Study Design: Cohort Study., Methods: Twenty healthy female runners and 17 female runners with chronic PFP symptoms were enrolled. Subjects completed the Knee injury and Osteoarthritis Outcome Score for Patellofemoral Pain (KOOS-PF), University of Wisconsin Running Injury and Recovery Index (UWRI), and the Brief Pain Inventory (BPI). QST consisted of pressure pain threshold testing to three local and three distant sites to the knee, heat temporal summation, heat pain threshold, and conditioned pain modulation. Data was analyzed utilizing independent t-tests for comparison of between-group data, effect sizes for QST measures (Pearson's r), and Pearson's correlation coefficient between pressure pain threshold values at the knee and functional testing., Results: The PFP group exhibited significantly lower scores on the KOOS-PF (p<0.001), BPI Pain Severity and Interference Scores (p<0.001), and UWRI (p<0.001). Primary hyperalgesia, identified through decreased pressure pain threshold at the knee, was detected in the PFP group at the central patella (p<0.001), lateral patellar retinaculum (p=0.003), and patellar tendon (p=0.006). Secondary hyperalgesia, a sign of central sensitization, was observed via differences in pressure pain threshold testing for the PFP group at the uninvolved knee (p=0.012 to p=0.042), involved extremity remote sites (p=0.001 to p=0.006), and uninvolved extremity remote sites (p=0.013 to p=0.021)., Conclusion: Compared to healthy controls, female runners with chronic PFP symptoms exhibit signs of both peripheral sensitization. Despite actively participating in running, nervous system sensitization may contribute to continued pain in these individuals. For female runners with chronic PFP, physical therapy management may need to include interventions which address signs of central and peripheral sensitization., Level of Evidence: Level 3., Competing Interests: The authors have no conflicts of interest to disclose.

Purpose: For individuals receiving maintenance dialysis, estimating accurate resting energy expenditure (REE) is essential for achieving energy balance, and preventing protein-energy wasting. Dialysis-specific, predictive energy equations (PEEs) offer a practical way to calculate REE. Three PEEs have been formulated via similar methods in different demographic samples; the Maintenance Haemodialysis Equation (MHDE REE), Vilar et al. Equation (Vilar REE) and the Fernandes et al. Equation (Cuppari REE). We compared them in a US cohort and assessed precision relative to measured REE (mREE) from indirect calorimetry. Because of expected imprecision at the extremes of the weight distribution, we also assessed the PEEs stratified by body mass index (BMI) subgroups., Methods: This analysis comprised of 113 individuals from the Rutgers Nutrition and Kidney Database. Estimated REE (eREE) was calculated for each PEE, and agreement with mREE was set at > 50% of values within the limits of ±10%. Reliability and accuracy were determined using intraclass correlation (ICC) and a Bland Altman plot, which analysed the percentage difference of eREE form mREE., Results: Participants were 58.4% male and 81.4% African American. Mean age was 55.8 ± 12.2 years, and the median BMI was 28.9 (IQR = 25.3 - 34.4) kg/m 2 . The MHDE REE achieved 58.4% of values within ±10% from mREE; Cuppari REE achieved 47.8% and Vilar REE achieved 46.0% agreement. Reliability was good for the MHDE REE (ICC = 0.826) and Cuppari REE (ICC = 0.801), and moderate for the Vilar REE (ICC = 0.642) ( p  < .001 for all). The equations performed poorly at the lowest and highest BMI categories., Conclusion: Dialysis-specific energy equations showed variable accuracy. When categorized by BMI, the equations performed poorly at the extremes, where individuals are most vulnerable. Innovation is needed to understand these variances and correct the imprecision in PEEs for clinical practice.KEY MESSAGESPotentially impacting over millions of patients worldwide, our long-term goal is to understand energy expenditure (EE) across the spectrum of CKD (stages 1-5) in adults and children being treated with dialysis or transplantation, with the intent of providing tools for the health professional that will improve the delivery of quality care.Our research has identified and focussed on disease-specific factors which account for 60% of the variance in predicting EE in patients on MHD, but significant gaps remain.Thus, our central hypotheses are that (1) there are unique disease-specific determinants of EE and (2) prediction of EE for individuals diagnosed with CKD can be vastly improved with a model that combines these factors with more sophisticated approaches.

Individuals diagnosed with serious mental illness (SMI) have greater trauma exposure and are at increased risk for posttraumatic stress disorder (PTSD). However, PTSD is rarely documented in their clinical records. This study investigated the predictors of PTSD documentation among 776 clients with SMI receiving public mental health services, who had probable PTSD as indicated by a PTSD Checklist score of at least 45. Only 5.3% of clients had PTSD listed as a primary diagnosis, and 8.4% had PTSD as a secondary diagnosis, with a total 13.7% documentation rate. PTSD documentation rate was highest for clients with major depression (18.8%) compared to those with schizophrenia (4.1%) or bipolar disorder (6.3%). Factors that predicted a lower likelihood of having a chart diagnosis of PTSD included being diagnosed with schizophrenia/schizoaffective disorder or bipolar disorder. Factors that predicted a higher likelihood of having a chart diagnosis of PTSD included being of non-white race, being female, and experiencing eight or more types of traumatic events. Findings highlight the need for PTSD screening and trauma informed care for clients with SMI receiving public mental health services., Competing Interests: Declaration of Competing Interest None., (Copyright © 2022 Elsevier Ltd.

Objective: To determine whether cognitive and psychological symptom profiles differentiate clinical diagnostic classifications (eg, history of mild traumatic brain injury [mTBI] and posttraumatic stress disorder [PTSD]) in military personnel., Methods: US Active-Duty Service Members ( N = 209, 89% male) with a history of mTBI ( n = 56), current PTSD ( n = 23), combined mTBI + PTSD ( n = 70), or orthopedic injury controls ( n = 60) completed a neuropsychological battery assessing cognitive and psychological functioning. Latent profile analysis was performed to determine how neuropsychological outcomes of individuals clustered together. Diagnostic classifications (ie, mTBI, PTSD, mTBI + PTSD, and orthopedic injury controls) within each symptom profile were examined., Results: A 5-profile model had the best fit. The profiles differentiated subgroups with high (34.0%) or normal (21.5%) cognitive and psychological functioning, cognitive symptoms (19.1%), psychological symptoms (15.3%), and combined cognitive and psychological symptoms (10.0%). The symptom profiles differentiated participants as would generally be expected. Participants with PTSD were mainly represented in the psychological symptom subgroup, while orthopedic injury controls were mainly represented in the high-functioning subgroup. Further, approximately 79% of participants with comorbid mTBI and PTSD were represented in a symptomatic group (∼24% = cognitive symptoms, ∼29% = psychological symptoms, and 26% = combined cognitive/psychological symptoms). Our results also showed that approximately 70% of military personnel with a history of mTBI were represented in the high- and normal-functioning groups., Conclusions: These results demonstrate both overlapping and heterogeneous symptom and performance profiles in military personnel with a history of mTBI, PTSD, and/or mTBI + PTSD. The overlapping profiles may underscore why these diagnoses are often difficult to diagnose and treat, but suggest that advanced statistical models may aid in identifying profiles representing symptom and cognitive performance impairments within patient groups and enable identification of more effective treatment targets., Competing Interests: The authors declare no conflicts of interest., (Copyright © 2022 Wolters Kluwer Health, Inc.

Background: One previous study examined implementation of evidence-based nutrition practice guidelines (EBNPG)., Objectives: To describe alignment of registered dietitian nutritionists' (RDNs) documented nutrition care with the Academy of Nutrition and Dietetics' EBNPG for Type 1 and Type 2 diabetes and examine impact of a midpoint training on care alignment with the guideline., Methods: In this 2-year, quasi-experimental study, 19 RDNs providing outpatient medical nutrition therapy to adults with diabetes ( n = 562) documented 787 initial and follow-up encounters. At study midpoint, RDNs received a guideline content training. A validated, automated tool was used to match standardized nutrition care process terminology (NCPT) in the documentation to NCPT expected to represent guideline implementation. A congruence score ranging from 0 (recommendation not identified) to 4 (recommendation fully implemented) was generated based on matching. Multilevel linear regression was used to examine pre-to-post training changes in congruence scores., Results: Most patients (~75%) had only one documented RDN encounter. At least one guideline recommendation was fully implemented in 67% of encounters. The recommendations "individualize macronutrient composition" and "education on glucose monitoring" (partially or fully implemented in 85 and 79% of encounters, respectively) were most frequently implemented. The mean encounter congruence scores were not different from pre-to-post guideline training ( n = 19 RDNs, 519 encounters pre-training; n = 14 RDNs, 204 encounters post-training; β = -0.06, SE = 0.04; 95% CI: -0.14, 0.03)., Conclusions: Most RDN encounters had documented evidence that at least one recommendation from the EBNPG was implemented. The most frequently implemented recommendations were related to improving glycemic control. A midpoint guideline training had no impact on alignment of care with the guideline., Competing Interests: Authors EL-J, KKe, and CP are employees of the Academy of Nutrition and Dietetics, which has a financial interest in the Academy of Nutrition and Dietetics Health Informatics Infrastructure platform and the Nutrition Care Process Terminology described in this article.

Persons with traumatic spinal cord injury (SCI) have severe bone loss below the level of lesion with the distal femur (DF) and proximal tibia (PT) being the skeletal regions having the highest risk of fracture. While a reference areal bone mineral density (aBMD) database is available at the total hip (TH) using the combined National Health and Nutrition Examination Survey (NHANES) III study and General Electric (GE) combined (GE/NHANES) to calculate T-score (T-score GE/NHANES ), no such reference database exists for aBMD of the DF, and PT. The primary objectives of this study were (1) to create a reference dataset of young-healthy able-bodied (YHAB) persons to calculate T-score (T-score YHAB ) values at the DF and PT, (2) to explore the impact of time since injury (TSI) on relative bone loss in the DF and PT regions using the two computation models to determine T-score values, and (3) to determine agreement between T-score values for a cohort of persons with SCI using the (T-score YHAB ) and (T-score GE/NHANES ) reference datasets. A cross-sectional prospective data collection study. A Department of Veterans Affairs Medical Center and a Private Rehabilitation Hospital. A normative reference aBMD database at the DF and PT was collected in 32 male and 32 female Caucasian YHAB participants (n=64) and then applied to calculate T-score values at the DF and PT in 105 SCI participants from a historical cohort. The SCI participants were then grouped based on TSI epochs (E-I: TSI < 1y, E-II: TSI 1-5y, E-III: TSI 6-10y, E-IV: TSI 11-20y, E-V: TSI > 20y). N/A. The knee and hip aBMD values were obtained by dual energy X-ray absorptiometry (GE Lunar iDXA) using standard clinical software for proximal femur orthopedic knee software applications. There were no significant differences in mean aBMD values across the four YHAB age subgroups (21-25, 26-30, 31-35, and 36-40 yr of age) at the TH, DF, and PT; mean aBMD values were higher in men compared to the women at all skeletal regions of interest. Using the mean YHAB aBMD values to calculate T-score values at each TSI epoch for persons with SCI, T-score values decreased as a function of TSI, and they continued to decline for 11-20 yr. Moderate kappa agreement was noted between the YHAB and the GE/NHANES reference datasets for the T-score cutoff criteria accepted to diagnose osteoporosis (i.e., SD <-2.5). A homogeneous reference dataset of YHAB aBMD values at the DF and PT was applied to calculate T-score values in persons with chronic SCI. There was a moderate level of agreement at the TH between the YHAB and GE/NHANES reference datasets when applying the conventional T-score cutoff value for the diagnosis of osteoporosis., (Published by Elsevier Inc.)

Purpose: The purpose of this study was to assess the effect of Team Strategies and Tools to Enhance Performance and Patient Safety (TeamSTEPPS) on student self-perceived competencies and perceptions of interprofessional (IP) communication and teamwork in a clinical case review activity. TeamSTEPPS is an evidence-based curriculum that is used to enhance and support IP healthcare communication., Methods: A repeated-measures, pretest/posttest study evaluated physician assistant students' and student pharmacists' perceptions of TeamSTEPPS. Students completed Performance Assessment for Communication and Teamwork (PACT) surveys, evaluating teamwork, knowledge, attitudes, and skills perceptions before and after a TeamSTEPPS lecture and associated activity with peer feedback., Results: Overall, 87.4% (n = 429) completed pre- and post-PACT surveys. Apart from the Mutual Support domain (p = .898), all changes were significantly positive (p < .004), with the greatest improvements occurring in the Attitudes and Perceived Skills domains., Conclusion: TeamSTEPPS IP education, application, and peer feedback improved students' perceptions of multiple domains, including effective communication. Using TeamSTEPPS tools in IP formats enabled the students to safely practice and collaborate in preparation for clinical practice., Competing Interests: The authors declare no conflict of interest., (Copyright © 2022 Physician Assistant Education Association.)

Rationale & Objective: People receiving maintenance hemodialysis (HD) experience significant activity barriers but desire the ability to do more and remain independent. To learn about how to help people who require dialysis stay active, a mixed methods study was designed to assess functional status and explore participants' lived activity experiences., Study Design: A concurrent mixed methods design was chosen to increase understanding of the real-life activity experiences of people who require dialysis through in-depth interviews paired with functional status measures. The qualitative findings were fully integrated with the quantitative results to link characteristics associated with different physical activity levels., Setting & Participants: A purposive sample of 15 adult patients receiving maintenance HD for at least 3 months was recruited from 7 dialysis centers in Newark, New Jersey., Analytical Approach: Thematic analysis using principles of interpretive phenomenology. Fully integrated quantitative and qualitative data with joint displays and conversion mixed methods., Results: Participants had a median age of 58 years and were predominantly African American (83%) and men (67%). Three descriptive categories were generated about the participants. They described physical activity as a routine daily activity rather than structured exercise. All participants experienced substantial hardship in addition to chronic kidney disease and expressed that family, friends, and faith were essential to their ability to be active. An overarching theme was generated for participants' mindsets about physical activity. Within the mindset theme, we discerned 3 subthemes comprising characteristics of participants' mindsets by levels of engagement in physical activity., Limitations: While code saturation and trends in functional status measures were achieved with 15 participants, a larger sample size would allow for deeper meaning saturation and statistical inference., Conclusions: Patients receiving maintenance HD with an engaged mindset exhibited more adaptive coping skills, moved more, wanted to help others, and had a normal body weight habitus. These participants employed adaptive coping skills to carry out daily life activities of importance, highlighting the value of adaptive coping to help overcome the challenges of being physically active., (© 2022 The Authors.)

Background: Preoperative malnutrition adversely impacts perioperative outcomes among patients with gastrointestinal (GI) cancer. The attributable risk (AR) that nutrition status contributes towards negative outcomes is poorly understood., Methods: Adults undergoing GI cancer surgeries were identified within the American College of Surgeons National Surgical Quality Improvement Program database (2005-2017). Emergency surgeries, outpatients, and cases with an American Society of Anesthesiologists status above III were excluded. Adjusted multivariable models were constructed to determine the associations between markers of nutrition status (body mass index, >10% weight loss in last 6 months, functional status, and serum albumin level) and adverse perioperative outcomes (presence and number of complications, death, 30-day readmission, and length of stay). Predictive accuracy statistics and population AR (PAR) were determined., Results: The final sample included 78,662 cases. Patients with >10% weight loss 6 months preceding surgery (compared with those who did not), had a significantly increased risk of complications (Relative Risk = 1.28; 95% CI, 1.20-1.37) and odds of death (odds ratio [OR] = 1.37; 95% CI, 1.18-1.59). A totally dependent functional status (compared with independent status) was associated with a 3.3-times higher odds of death (OR = 3.30; 95% CI, 1.53-7.15). Multivariable models were not predictive of adverse outcomes; PAR from the markers ranged 1%-2%., Conclusion: Ten percent weight loss in preceding 6 months was associated with increased risk of adverse perioperative outcomes among adults undergoing GI cancer surgery. The contribution of nutrition status markers to surgical outcomes as assessed by PAR was small (1%-2%), a finding not previously reported. Future intervention studies should include validated nutrition risk markers, control for effects of perioperative variables, and evaluate PAR within the immediate/long-term postoperative periods., (© 2021 American Society for Parenteral and Enteral Nutrition.)

Objective: To compare two methods of knowledge broker support to improve standardized assessment use., Design: Two-site cluster randomized trial., Setting: Acute rehabilitation hospital., Participants: 18 physical therapists., Intervention: A 10-month intervention was collaboratively designed with an external knowledge broker and physical therapists to compare full and partial implementation support. The knowledge broker provided education and strategies for implementation to the fully supported group and recommended strategies to the partially supported group that they self-implemented., Measurement: Chart audit data documenting frequency of use was extracted at four timepoints. Ten focus groups were conducted to describe factors that influenced use. Focus group data were coded using the Consolidated Framework for Implementation Research and rated as barriers and facilitators for standardized assessment use., Results: For the fully supported group, standardized assessment use at initial examination increased from 0% to 58.3% at month 2 and decreased to 17.6% and 11.8% at months 4 and 8-10. For the partially supported group, standardized assessment use increased from 0% to 46% and 50% at month 2 and 4 and decreased to 2.8% at months 8-10. For both groups, early use was seen multiple facilitators. At month 10, barriers included organizational changes that impacted intervention fit. In addition, the fully supported group didn't value the selected standardized assessment and the partially supported group lacked space., Conclusions: Knowledge broker support improved both groups standardized assessment use early on, but it was not sustained. The amount of support could not be isolated as factors that influenced use varied by groups.

Background/objective: Older adults are at higher risk of malnutrition. The aim of this study was to explore associations between nutritional status and dentition status among older adults seeking care in a dental clinic., Methods: This was a cross-sectional study of data from older adults (65-89 y) who received care at a northeastern US urban dental school clinic between June 2015 and June 2020 ( N = 305). Clinical and demographic data were obtained from the electronic health record; nutritional status was determined using the Self-Mini Nutritional Assessment (Self-MNA), and odontograms and digital radiography were used to determine dental data. Adjusted multivariable models were used to explore associations between variables., Results: The sample was 53.8% female with a median age of 72.0 y. The median Self-MNA score was 13, reflective of normal nutritional status; 29.5% were at risk of or had malnutrition. Median numbers of teeth and posterior and anterior occluding pairs of teeth (POP, AOP) were 18.0, 2.0, and 5.0, respectively. Those with normal nutritional status had significantly more teeth, POPs, and AOPs than those at risk of or with malnutrition ( P = 0.015, P = 0.015, and P = 0.039, respectively). Every additional unit increase in the number of natural or restored teeth or POP was associated with significantly lower odds of being at risk of or with malnutrition (3% and 13%, respectively). Having functional dentition was associated with 46% lower odds of being at risk of or with malnutrition., Conclusion: This study demonstrated that older adults who had more teeth, better occlusion, and functional dentition were more likely to be of normal nutritional status than those who had less teeth, had poorer occlusion, and lacked functional dentition. Further research with larger, more diverse samples and varied measures of dentition are needed to better understand the associations between nutritional status and dentition status., Knowledge Transfer Statement: The findings from this study suggest that older adults with fewer teeth and therefore less efficient occlusion are at higher risk for malnutrition than those with more teeth and better occlusion. Health care professionals should include screening for dentition and malnutrition as part of their routine practice to identify patients who may have tooth loss and be at risk of malnutrition and refer them accordingly for interventions to optimize oral health and nutritional status.

Background/objective: Older adults are at risk for tooth loss and compromised nutritional status. Our objective was to conduct a systematic review and meta-analysis to answer the following question: Among adults aged ≥60 y living in developed countries, what are the associations between tooth loss and nutritional status as assessed by a validated nutrition screening or assessment tool?, Methods: PRISMA guidelines were followed. PubMed, Scopus, CINAHL, Web of Science, and MEDLINE were searched for studies published in English between 2009 and 2019 that met inclusion criteria. Data extracted included study and participant characteristics, dentition, and nutritional status. Risk of bias was assessed with a modified Newcastle-Ottawa Scale. Random effects meta-analysis was used., Results: Of the 588 unduplicated articles identified, 78 were reviewed in full text, and 7 met inclusion criteria. Six studies were combined for a meta-analysis, which revealed that individuals who were completely edentulous or who lacked functional dentition had a 21% increased likelihood of being at risk of malnutrition or being malnourished, as compared with those who were dentulous or had functionally adequate dentition (risk ratio, 1.21; 95% CI, 1.11 to 1.32; I 2 = 70%). Whether the article statistically adjusted for medical history explained most of the heterogeneity in the pooled effect., Conclusions and Implications: Findings suggest that older adults with tooth loss are at greater risk of malnutrition than those with functionally adequate dentition. Use of validated tools to assess risk of malnutrition in older adults with tooth loss is important to promote early intervention and referral to optimize nutrition and oral health status. Findings were limited by heterogeneity, risk of bias, and overall quality of the studies reviewed. Cohort studies that adjust for known confounders and use consistent approaches to assess tooth loss and nutritional status are needed., Knowledge Transfer Statement: The results of this study suggest that older adults with tooth loss are at greater risk of malnutrition than those with functionally adequate dentition. Screening of this population for malnutrition by health care professionals, including dentists and dietitians, may result in corresponding referrals to optimize nutrition and oral health status. Further research is needed with consistent approaches to assess tooth loss and nutritional status.

This is the first real-world study to examine the association between a voluntary 16-ounce (oz) portion-size cap on sugar-sweetened beverages (SSB) at a sporting arena on volume of SSBs and food calories purchased and consumed during basketball games. Cross-sectional survey data from adults exiting a Brooklyn, NY, USA arena (Barclays, n = 464) with a 16-oz portion-size restriction and a Manhattan, NY, USA arena with no portion-size restriction (Madison Square Garden, control, n = 295) after the portion cap policy was put in place from March through June 2014 were analyzed. Linear regression models adjusting for sex, age, BMI, ethnicity, race, marital status, education, and income were used to compare the two arenas during the post-implementation period. The survey response rate was 45.9% and equivalent between venues. Among all arena goers, participants at Barclays purchased significantly fewer SSB oz (-2.24 oz, 95% CI [-3.95, -0.53], p = .010) and consumed significantly fewer SSB oz (-2.34 oz, 95% CI[-4.01, -0.68], p = .006) compared with MSG after adjusting for covariates. Among those buying at least one SSB, Barclays' participants purchased on average 11.03 fewer SSB oz. (95% CI = [4.86, 17.21], p < .001) and consumed 12.10 fewer SSB oz (95% CI = [5.78, 18.42], p < .001). There were no statistically significant differences between arenas in food calories and event satisfaction. In addition, no one reported not ordering a drink due to small size. An SSB portion-size cap was associated with purchasing and consuming fewer SSB oz. without evidence of decreasing satisfaction with the event experience., Competing Interests: C.A.

Purpose: The purpose of this study was to retrospectively compare the exam performance of physician assistant (PA) students given asthma instruction in a flipped classroom with PA students in a traditional lecture setting while controlling for students' previous academic performance and clinical asthma experience., Methods: Three cohorts of PA students (n = 146) from the years 2017 (traditional-lecture setting) and 2018 and 2019 (flipped-classroom setting) were included in the study. Academic performance across cohorts was compared using answers to 11 exam questions reflective of the asthma content., Results: Findings demonstrated significantly greater performance in the flipped classroom compared with traditional lecture. The 2018 and 2019 cohorts scored 9.4% and 13.2% higher, respectively, compared with the 2017 cohort. Exam performance of students with a low likelihood of clinical exposure to asthmatic patients before PA school was similar to those with a high likelihood., Conclusion: This study found improved exam performance with a flipped classroom. The flipped classroom represents a potential opportunity to maximize similar performances by both less experienced students and more experienced students., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Physician Assistant Education Association.)

Background: Participation in a student-run pro bono clinic (SRPBC) provides opportunities for students to develop professional skills, engage with the community, and provide an often-underserved population with needed care., Materials and Methods: This paper describes the results of a mixed-method analysis of student experiences in an SRPBC. A survey with both Likert-type and write-in elements was administered to three cohorts of students enrolled in a doctoral program of physical therapy. Students were prompted to provide their perspective on the value of the clinic experience with respect to professional development, academic relevancy, and personal growth., Results: The analysis discovered that perspective value of the clinic in the areas of personal growth and academic relevancy differed by cohort. Specifically, 1 st -year students reported that they benefitted immensely by learning from their peers, especially in the use of outcome measures. Second-year students did not report the same benefits., Conclusion: The findings suggest that even though students from different cohorts work together in the same clinic, they may experience the clinic very differently. This observation provided the basis for changes to the SRPBC to enhance leadership and conflict management skills of the 2 nd -year students., Competing Interests: There are no conflicts of interest., (Copyright: © 2021 Journal of Education and Health Promotion.)

Introduction: Impairments in cognitive performance after sport-related concussion (SRC) typically resolve within weeks of the injury, whereas alterations to white matter (WM) organization have been found to persist longer into the chronic injury stage. However, longer-term associations between cognition and WM organization following SRC have not been studied. The objective of this study was to compare WM organization and cognitive performance in collegiate athletes an average of almost 4 years post-SRC to athletes with no history of SRC., Method: National Collegiate Athletic Association Division III athletes (n = 71, age = 19.3 ± 1.2; 14 with self-reported SRC) completed a neurocognitive assessment and diffusion tensor imaging (DTI). WM organization was assessed by extracting measures of fractional anisotropy (FA), mean diffusivity (MD), and radial diffusivity (RD) from 20 WM regions of interest (ROIs). Multivariate partial least squares analyses were used to compare athletes with and without a history of SRC and assess relationships between DTI-derived metrics of WM organization and cognitive measures., Results: Cognitive performance and ROI metrics did not differ between athletes with and without prior SRC. However, among athletes with a history of SRC, better executive function, processing speed, and memory but worse choice reaction time were associated with higher FA and lower MD and RD in several WM tracts., Conclusion: Athletes with a history of SRC demonstrated greater associations between cognitive performance and WM organization, but also variability in the domains showing associations. Taken together, the findings demonstrate the importance of examining brain-behavior relationships several years after SRC to better gauge how WM organization supports cognition.

Purpose: Physician assistant (PA) programs aim to foster a collaborative culture that enables stakeholders to feel included, empowered, and valued. The purpose of this study was to explore the cultural climate of diversity and inclusion in one PA program to identify areas of strength and to serve as a baseline needs assessment for future program initiatives., Methods: The study used a cross-sectional, descriptive approach for PA survey data (N = 85) to assess perceptions of diversity and inclusion of PA program students, faculty, and staff., Results: The respondents largely agreed that the program created an inclusive learning environment (92%), the curriculum positively affected their understanding of diversity and cultural responsiveness (84.6%), and the program had an adequate amount of inclusivity for all program stakeholders (87%). Some faculty members (25%) and students (6.2%) disagreed that faculty were open to diverse political beliefs, and 35% of the respondents believed that more emphasis could be put on religious diversity. A few students (7.7%) perceived faculty as not supportive of non-native English language speakers; students of color (11.5%) were more likely than White students (5.1%) to have this perception., Conclusions: This study largely met the goal to create a professional environment of mutual respect and, ultimately, a climate of inclusiveness. It also identified opportunities for new initiatives to meet the needs of all program stakeholders. Follow-up research that distinguishes faculty from students and a multicenter study to explore perspectives based on demographic differences would be timely and useful., Competing Interests: The authors declare no conflict of interest., (Copyright © 2021 Physician Assistant Education Association.)

Background: Laboratory and other healthcare professionals participate in developing clinical practice guidelines through systematic review of the evidence. A significant challenge is the identification of areas for analytic focus when the evidence consists of several categories of interventions and outcomes that span both laboratory and clinical processes. The challenge increases when these interventions present as sets of combined interventions. A scoping review may provide a transparent and defensible analytic route forward for systematic reviews challenged in this manner., Content: A scoping review was carried out to characterize the evidence on rapid identification of bloodstream infections. Fifty-five studies previously identified by the supported systematic review were charted in duplicate. Charted records were analyzed using descriptive content analysis and evidence mapping with a 5-step process., Summary: The 5-step analysis culminated in the characterization of 9 different intervention chain configurations that will facilitate the comparison of complex intervention practices across studies. Furthermore, our evidence map indicates that the current evidence base is strongly centered on 3 specific clinical outcomes, and it links these outcomes to the most represented intervention chain configurations. The scoping review effort generated a route forward for the supported systematic review and meta-analysis., (© American Association for Clinical Chemistry 2021. All rights reserved.

Objective: The present study investigates the organization of primary care behavioral health within student health centers and assesses the relationship between organizational structure and practice integration among physical and mental health services. Methods: We collaborated with the American College Health Association to distribute a 54 item survey to representatives of each ACHA member institution. Results: A total of 189 (26.3%) surveys were obtained and included 86 (46%) integrated (health/counseling) centers and 101 (54%) nonintegrated centers. Significant differences in levels of practice integration were noted between these two groups. Significant correlations were found between levels of practice integration and the presence of behavioral health staff. Conclusions: The organization and delivery of physical and behavioral healthcare services for students is considerably integrated and collaborative. Adding behavioral health clinicians to the primary care college health setting increases integrated care practice without embarking on full administrative integration of physical and mental health services.

Aim: To examine whether neck strength and symmetry are associated with psychological function in athletes with exposure to repetitive head impacts., Methods: Collegiate soccer (n = 29) and limited/noncontact (n = 63) athletes without a history of concussion completed the Brief Symptom Inventory 18 and assessments of isometric neck strength. Neck strength symmetry was calculated as the difference in strength between opposing muscle groups., Results: The results demonstrated that lower neck strength was associated with more symptoms of anxiety, whereas asymmetry in neck strength was associated with more symptoms of somatization and depression in soccer athletes only., Conclusion: These preliminary results suggest that greater neck strength/symmetry is related to better psychological function in athletes who have higher exposure to repetitive head impacts., Competing Interests: Financial & competing interests disclosure Financial support was provided to C Esopenko through the School of Health Professions, Rutgers Biomedical and Health Sciences under the School of Health Professions Intramural Research Grant and to JF Buckman through the NIH under grant K02AA025123.

Objective: The purpose of this study was to compare disability in people with HIV and peripheral neuropathy with those without neuropathy and explore how neuropathy and other relevant factors are associated with disability., Methods: In this cross-sectional study, participants completed the Brief pain inventory, Beck Depression Inventory II, World Health Organization Disability Assessment Schedule (WHODAS 2.0), and a health and demographic questionnaire. Additional data were extracted from the medical record. A raw score of ≥1 on the Subjective Peripheral Neuropathy Screen questions about lower extremity numbness or paresthesia was used to identify peripheral neuropathy. Predictors of disability (as determined by association with World Health Organization Disability Assessment Schedule 2.0 scores) were evaluated bivariately and in a multivariable model. Path modeling was used to identify a parsimonious model to elucidate the mediated effects of peripheral neuropathy on disability., Results: Participants with peripheral neuropathy had more depression symptoms, more pain (severity and interference), and higher disability scores compared with participants without neuropathy. The relationship between neuropathy and disability was mediated by pain interference and depression (standardized root mean residual = .056)., Conclusion: In this sample of people with HIV, those with lower extremity peripheral neuropathy reported more severe disability, worse pain, and more depression symptoms than those without neuropathy. The relationship between peripheral neuropathy and disability may be mediated though pain interference and depression., Impact: Distal sensory polyneuropathy is a common comorbidity experienced by people living with HIV and frequently causes pain. This study can help providers direct care toward lessening disability experienced among people with HIV and peripheral neuropathy by targeting interventions for treatment of pain and depression., Lay Summary: People living with HIV may experience disabling painful neuropathy. Treatment for pain and depression may help reduce the disability associated with painful neuropathy., (© The Author(s) 2020.

As the Cytotechnology Program Review Committee (CPRC) shared its intent to transition all undergraduate and certificate training programs to a Master's degree curriculum by 2022, mixed opinions have been expressed by various stakeholders from the larger pathology and allied health communities. In order to build a consensus path forward, a framework entitled "Walk in the Woods," an international diplomacy approach, is described. Unlike many problem-solving approaches which directly identify a problem and potential solutions, this approach is a four-step process which includes: (1) self-interest, (2) enlarged interest, (3) enlightened interest, and (4) aligning interest; each step builds on the preceding step. While four steps may take longer than the traditional "problem to solution" paradigm, the purpose of each step is to increase transparency and clarity in a complex multiparty negotiation, such as the path forward for cytotechnology. This commentary demonstrates, in a step-by-step manner, how a "Walk in the Woods" can aid in the facilitation of the transition of the cytology degree to an entry-level Master's degree curriculum and evidence- and interest-based negotiation approach.

Objective: To identify T -score values at the total hip (TH) and femoral neck (FN) that correspond to the cutoff value of <0.60 g/cm 2 for heightened risk of fracture at the distal femur (DF) and proximal tibia (PT ). Design: Retrospective analysis of data in a research center's database. Setting: Community-based individuals with spinal cord injury (SCI). Participants: 105 unique individuals with SCI. Outcome Measurements: DXA derived areal BMD (aBMD) and T -score of the DF, PT, TH, and FN. Results: The aBMD at the DF and PT regions were predictors of T -scores at the TH ( R 2  = 0.63, P  < 0.001 and R 2  = 0.65, P  < 0.001) and FN ( R 2  = 0.55, P  < 0.001 and R 2  = 0.58, P  < 0.001). Using the DF and PT aBMD of 0.60 g/cm 2 as a value below which fractures were more likely to occur, the predicted T -score was -3.1 and -3.5 at the TH and -2.6 and -2.9 at the FN, respectively. However, when the predicted and observed T -score values disagree outside the 95% limit of agreement, the predicted T -score values are lower than the measured T -score values, overestimating the measured values between -2.0 and -4.0 SD. Conclusion: The DF and PT cutoff value for aBMD of 0.60 g/cm 2 was a moderate predictor of T -score values at the TH and FN, with considerable inaccuracies outside the clinically acceptable limits of agreement. As such, the direct measurement of knee aBMD in persons with SCI should be performed, whenever possible, prior to prescribing weight bearing upright activities, such as robotic exoskeletal-assisted walking.

Background and Purpose: Although outcome measures are a valuable part of physical therapy practice, there is a gap in routine outcome measurement use by physical therapists (PTs). Knowledge brokers (KBs) are individuals who can collaborate with PTs to facilitate outcome measure use. The purpose of this study was to determine whether an intervention tailored by an external KB, cocreated with the PTs and supported by the supervisor, would increase the use of gait speed by PTs working at an inpatient subacute rehabilitation hospital., Methods: A mixed-methods study was conducted with 11 PTs. The 2-month intervention included education, documentation changes, audit and feedback, goal setting, and organizational support. Use of the 4-meter walk test was measured through chart audits and was self-assessed with the Goal Attainment Scale. Proportions were calculated to determine the number of times gait speed was documented by the PTs both at initial examination (IE) and at discharge. A repeated-measures analysis of variance was used to determine significant differences from baseline (3-month retrospective chart audit), 0 to 2, 2 to 4, 4 to 6, and 6 to 8 months. A Wilcoxon signed rank test was used to determine significant differences in self-reported use on the Goal Attainment Scale month 0 to month 2. Focus groups immediately following the intervention (month 2) and at follow-up (month 9) were used to determine barriers to measuring gait speed and perceptions of the intervention. Open coding was used to identify key themes. A comparison group of per diem PTs was trained by the supervisor between months 4 and 8, using the approach developed by the KB. The comparison group was included as their training may have influenced the experimental groups' outcome. Chart audit data for the comparison group from months 0 to 2, 2 to 4, 4 to 6, and 6 to 8 were reported descriptively., Results and Discussion: Documentation of the 4-meter walk test significantly improved from the 3-month retrospective chart audit at baseline (0% IE, 0% discharge) to months 0 to 2 at IE (mean = 71%, SD = 31 %, F = 9.30, P < .001) and discharge (mean = 66%, SD = 30%, F = 14.16, P < .001) and remained significantly higher at months 6 to 8 follow-up for IE (mean= 63%, SD 21%) and discharge (mean=59%, SD 32%). Eleven PTs participated in the focus group at month 2 and reported that the knowledge translation strategies including documentation changes, environmental cues, and social support helped facilitate their behavior change. Lack of space and the patient's activity limitations were barriers. The PTs significantly improved self-reported use of gait speed using the Goal Attainment Scale from month 0 to month 2 at IE: -2 to 0 (0% use to 50%) (Z = -2.842, P = .004) and discharge: -2 to 1 (0% use to 75%) (Z = -2.448, P = .014). The comparison group increased documented use of gait speed from 0% to 25% at IE and 47% at discharge between months 6 and 8., Conclusion: The KB, with supervisor support, successfully collaborated with the PTs to tailor an intervention to address local barriers to consistently use the 4-meter walk test. The PTs significantly improved the documented use of gait speed following the intervention. The PTs reported that the intervention facilitated outcome measure use although barriers to using gait speed remained.

This article seeks to outline the implementation of a longitudinal interprofessional education (IPE) program in the predoctoral curriculum at a U.S. dental school. The challenges of implementing the curriculum in a complex environment are reviewed, and an overview of the 4-year curriculum is offered, including exposure, immersion, and clinical readiness components. Results of developmental evaluations are reviewed. Respondents to surveys regarding the capstone case conference experiences overwhelmingly suggest the conferences were educationally rewarding as well as enriching for each of the health professions represented. While response was limited, alumni surveys also indicate satisfaction with the IPE experience. A discussion of challenges and suggestions regarding successful implementation and expansion of IPE programs from didactic to clinical settings are also included., (© 2020 American Dental Education Association.)

Persons with neurologically motor-complete spinal cord injury (SCI) have a marked loss of bone mineral density (BMD) of the long bones of the lower extremities, predisposing them to fragility fractures, especially at the knee. Denosumab, a commercially available human monoclonal IgG antibody to receptor activator of nuclear factor-κB ligand (RANKL), may provide an immunopharmacological solution to the rapid progressive deterioration of sublesional bone after SCI. Twenty-six SCI participants with subacute motor-complete SCI were randomized to receive either denosumab (60 mg) or placebo at baseline (BL), 6, and 12 months. Areal bone mineral density (aBMD) by dual energy x-ray absorptiometry (DXA) at 18 months at the distal femur was the primary outcome and aBMD of the proximal tibia and hip were the secondary outcomes analyzed in 18 of the 26 participants (denosumab, n = 10 and placebo, n = 8). The metrics of peripheral QCT (pQCT) were the exploratory outcomes analyzed in a subsample of the cohort (denosumab, n = 7 and placebo n = 7). The mean aBMD (±95% CI) for the denosumab versus the placebo groups demonstrated a significant group × time interactions for the following regions of interest at BL and 18 months: distal femoral metaphysis = mean aBMD 1.187; 95% CI, 1.074 to 1.300 and mean aBMD 1.202; 95% CI, 1.074 to 1.329 versus mean aBMD 1.162; 95% CI, 0.962 to 1.362 and mean aBMD 0.961; 95% CI, 0.763 to 1.159, respectively ( p  < 0.001); distal femoral epiphysis = mean aBMD 1.557; 95% CI, 1.437 to 1.675 and mean aBMD 1.570; 95% CI, 1.440 to 1.700 versus mean aBMD 1.565; 95% CI, 1.434 to 1.696 and mean aBMD 1.103; 95% CI, 0.898 to 1.309, respectively ( p = 0.002); and proximal tibial epiphysis = mean aBMD 1.071; 95% CI, 0.957 to 1.186 and mean aBMD 1.050; 95% CI, 0.932 to 1.168 versus mean aBMD 0.994; 95% CI, 0.879 to 1.109 and mean aBMD 0.760; 95% CI, 0.601 to 0.919, respectively ( p  < 0.001). Analysis of pQCT imaging revealed a continued trend toward significantly greater loss in total volumetric BMD (vBMD) and trabecular vBMD at the 4% distal tibia region, with a significant percent loss for total bone mineral content. Thus, at 18 months after acute SCI, our findings show that denosumab maintained aBMD at the knee region, the site of greatest clinical relevance in the SCI population. © 2020 The Authors.

Objective: The purpose of this study is to test the Nutrition-Specific Quality of Life (NSQOL) questionnaire for test-retest reliability and validity in a sample of patients on maintenance hemodialysis (MHD)., Design and Methods: Test-retest reliability of the NSQOL questionnaire via two patient interviews and comparison of the NSQOL questionnaire to a comprehensive nutrition assessment performed by a registered dietitian nutritionist for validity testing. This study was conducted in one outpatient MHD center in Chicago, IL. Adults, aged 18 years or older, treated with MHD for at least six months prior to start of the study. A Spearman's correlation coefficient was used to determine test-retest reliability and a Cronbach's alpha was used to determine the internal consistency of the 2 NSQOL questionnaires. Validity testing was done by comparing the NSQOL questionnaire to the most recent comprehensive nutrition assessment., Results: The sample consisted of 17 men (63%) and 10 women (37%), with a mean age of 60 ± 13, who were mostly African American (63%) and Caucasian (26%). There was a significant correlation (P = .001) between the initial NSQOL interview and repeat NSQOL interview in all questions except for question 14 (P = .100). The NSQOL questionnaire was found to have excellent internal consistency with an α = 0.900. No significant relationship was found among total NSQOL score and age, dialysis vintage, albumin, or normalized protein catabolic rate; however, older participants had lower total NSQOL questionnaire scores. Although not statistically significant, there was variability between NSQOL questionnaire score and nutritional status., Conclusions: The NSQOL questionnaire was found to be reliable and had high internal consistency in this sample of patients receiving MHD. The NSQOL questionnaire may be beneficial for monitoring nutrition quality of life changes in-between nutrition assessment intervals., (Copyright © 2019 National Kidney Foundation, Inc.

The US health care system has been undergoing substantial changes in reimbursement for medical and nutrition services. These changes have offered opportunities and challenges for registered dietitian nutritionists (RDNs) to bill for medical nutrition therapy and other nutrition-related services. During the past 10 years, the Academy of Nutrition and Dietetics has periodically surveyed RDNs providing medical nutrition therapy in ambulatory care settings to learn about their knowledge and patterns of coding, billing, and payment for their services. In 2018, the Academy of Nutrition and Dietetics conducted the latest iteration of this survey. This article compares the results of the 2008, 2013, and 2018 surveys to examine changes in RDNs' knowledge of billing code use and reimbursement patterns over time; understand the potential influences on coding and billing practices in a changing health care environment; and understand the effects of newer practice settings and care delivery models on billing and reimbursement for medical nutrition therapy services. Results from these surveys demonstrate that during the past 10 years RDNs' knowledge of billing and coding has been stable and very low for RDNs not in supervisory roles or private practice. RDNs reported an increase in providing medical nutrition therapy services to patients with multiple conditions. Since 2013, a dramatic increase was noted in the reported proportion of reimbursement from private/commercial health insurance plans. Results also indicate that most RDNs are not aware of changes in health care payment. Individual RDNs need to understand and be held accountable for the business side of practice and their value proposition in today's health care environment., (Copyright © 2020 Academy of Nutrition and Dietetics.

Background: Research contributions by registered dietitian nutritionists (RDNs) are important for enhancing the use of nutrition-related evidence-based guidelines in dietetics practice. Involvement of RDNs in research activities has been studied previously, but little is known about the drivers (motivators) of sustaining research involvement by RDNs who work in clinical practice., Objective: To identify key characteristics of established RDN clinician researchers and drivers that contributed to their sustained research involvement., Design: We used a convergent parallel mixed methods study design utilizing the clinician career research trajectory as a framework. Research involvement was examined using the Practice-Based Dietitian Research Involvement Survey (PBDRIS). Workplace support was assessed using the Research Capacity and Culture (RCC) survey. Semistructured interviews were used to investigate key themes in established RDN clinician researchers., Participants/setting: We identified 450 RDNs involved with research activities in the United States through hand-searching clinically relevant nutrition journals and contacted them to participate in an online survey. A total of 29 RDNs met criteria and completed (6.4%) the quantitative survey, then a subsample (n=10) participated in semistructured interviews to explore drivers for continued research involvement., Results: Research involvement scores (n=29) from the PBDRIS ranged from 60.0% to 97.5%, indicating involvement in higher-level research-related tasks by our sample participants. RCC results revealed the importance of workplace support and mentorship. Interviews with established RDN clinician researchers identified exposure, curiosity, and dedication as three overarching themes with eight subthemes driving continued research involvement., Conclusion: Based on the experiences of select RDN clinician researchers who have demonstrated success in sustaining their research involvement, we found that having an available mentor, support from their workplace environment, and personal drive were integral to their success., (Copyright © 2019 Academy of Nutrition and Dietetics.

[Purpose] This pilot study aims to determine whether improvements in postural sway, particularly among older adults, can be augmented immediately after training participants to activate and isolate the transverse abdominis (TrA) muscle. [Participants and Methods] Fifty six participants (in three age groups) took part in a single session TrA training intervention. Aspects of postural sway, balance and muscle activation patterns were measured before and after training and compared. [Results] There was significant improvement across four of six postural sway variables for the combined sample of all age groups. Older adults improved more than younger and middle-age participants in two important postural sway variables. No marked differences were evident in static reach distance across all age groups. There were no differences between groups with regard to surface electromyography (sEMG) amplitudes despite the emergence of different activation patterns among age groups. [Conclusion] Immediate effects were induced in postural sway measures after the single session training intervention. By improving neuromuscular control of the TrA and maximizing the efficiency of related proximal core muscles center of pressure (COP) sway velocities decreased during single limb standing (SLS)., Competing Interests: None declared., (2019©by the Society of Physical Therapy Science.

Background: We assessed the differences in postoperative feeding outcomes when comparing early and traditional diet advancement in patients who had an ostomy creation., Methods: At a U.S. tertiary care hospital, data from patients who underwent an ileostomy or colostomy creation from June 1, 2013, to April 30, 2017 were extracted from an institutional database. Patients who received early diet advancement (postoperative days 0 and 1) were compared with traditional diet advancement (postoperative day 2 and later) for demographics, preoperative risk factors, and operative features. The postoperative feeding outcomes included time to first flatus and ostomy output. Mann-Whitney U tests determined bivariate differences in postoperative feeding outcomes between groups. Poisson regression was used to adjust for unequal baseline characteristics., Results: Data from 255 patients were included; 204 (80.0%) received early diet advancement, and 51 (20.0%) had traditional diet advancement. Time to first flatus and time to first ostomy output were significantly shorter in the early compared with traditional diet advancement group (median difference of 1 day for both flatus and ostomy output, P < 0.001). Adjusting for baseline group differences (American Society for Anesthesiology Physical Status Classification System, surgical approach, resection and ostomy type) maintained the significant findings for both time to first flatus (β = 1.32, P = 0.01) and time to first ostomy output (β = 1.41, P < 0.001)., Conclusions: Early diet advancement is associated with earlier return of flatus and first ostomy output compared with traditional diet advancement after the creation of an ileostomy or colostomy., (© 2019 American Society for Parenteral and Enteral Nutrition.)

Background and Purpose : Little is known about the process of engaging key stakeholders to select and design a knowledge translation (KT) intervention to increase the use of an outcome measure using audit and feedback. The purpose of this case report was to describe the development of a KT intervention designed with organizational support to increase physical therapists' (PTs) use of a selected outcome measure in an inpatient sub-acute rehabilitation hospital. Case Description : Eleven PTs who worked at a sub-acute rehabilitation hospital participated. After determining organizational support, a mixed methods barrier assessment including a chart audit, questionnaire, and a focus group with audit and feedback was used to select an outcome measure and design a locally tailored intervention. The intervention was mapped using the Theoretical Domains Framework (TDF). One investigator acted as knowledge broker and co-designed the intervention with clinician and supervisor support. Outcomes : The 4-m walk test was selected through a group discussion facilitated by the knowledge broker. Support from the facility and input from the key stakeholders guided the design of a tailored KT intervention to increase use of gait speed. The intervention design included an interactive educational meeting, with documentation and environmental changes. Discussion : Input from the clinicians on the educational meeting, documentation changes and placement of tracks, and support from the supervisor were used to design and locally adapt a KT intervention to change assessment practice among PTs in an inpatient sub-acute rehabilitation hospital. Implementation and evaluation of the intervention is underway.

The evidence base for the optimal laboratory diagnosis of Clostridioides ( Clostridium ) difficile in adults is currently unresolved due to the uncertain performance characteristics and various combinations of tests. This systematic review evaluates the diagnostic accuracy of laboratory testing algorithms that include nucleic acid amplification tests (NAATs) to detect the presence of C. difficile The systematic review and meta-analysis included eligible studies (those that had PICO [population, intervention, comparison, outcome] elements) that assessed the diagnostic accuracy of NAAT alone or following glutamate dehydrogenase (GDH) enzyme immunoassays (EIAs) or GDH EIAs plus C. difficile toxin EIAs (toxin). The diagnostic yield of NAAT for repeat testing after an initial negative result was also assessed. Two hundred thirty-eight studies met inclusion criteria. Seventy-two of these studies had sufficient data for meta-analysis. The strength of evidence ranged from high to insufficient. The uses of NAAT only, GDH-positive EIA followed by NAAT, and GDH-positive/toxin-negative EIA followed by NAAT are all recommended as American Society for Microbiology (ASM) best practices for the detection of the C. difficile toxin gene or organism. Meta-analysis of published evidence supports the use of testing algorithms that use NAAT alone or in combination with GDH or GDH plus toxin EIA to detect the presence of C. difficile in adults. There is insufficient evidence to recommend against repeat testing of the sample using NAAT after an initial negative result due to a lack of evidence of harm (i.e., financial, length of stay, or delay of treatment) as specified by the Laboratory Medicine Best Practices (LMBP) systematic review method in making such an assessment. Findings from this systematic review provide clarity to diagnostic testing strategies and highlight gaps, such as low numbers of GDH/toxin/PCR studies, in existing evidence on diagnostic performance, which can be used to guide future clinical research studies., (Copyright © 2019 Kraft et al.)

Background: Nutrition specialists are considered key members of multicomponent pediatric weight management intervention teams, but to date, their contribution has not been quantified., Objective: The purpose of this systematic review was to estimate the effectiveness of interventions provided by treatment teams that include a nutrition specialist on pediatric weight management outcomes, including body mass index (BMI), BMI z score, and waist circumference when compared with treatment teams that do not include a nutrition specialist., Methods: The results of a comprehensive literature search and a systematic and more targeted update of that search were included in the meta-analyses: a search of controlled trials published between July 2005 and April 2012, conducted during the 2015 Pediatric Weight Management Update Project of the Academy of Nutrition and Dietetics Evidence Analysis Library, and an update search of controlled trials published between May 2012 and December 2015 focusing on a more specific topic within the previous search. Studies included overweight and/or obese patients aged 6 to 18 years receiving outpatient weight management treatment. Data extraction of all studies identified was performed using a standardized tool. The resulting data from the search and the systematic update were merged. Ninety-nine studies and 209 study arms were included in the analysis. An exploratory meta-analysis using alternative meta-analytic methods designed for complex, heterogenous interventions was conducted to identify relative contributions by intervention provider category at selected time points. Meta-regression analyses were used to evaluate significant differences from the reference category for each provider category., Results: The nutrition specialist-only condition resulted in increased reductions in BMI z score compared with behavioralist-only, combined nutrition specialist and behavioralist, and neither nutrition specialist or behavioralist category (reference) throughout the analysis. Meta-regression analysis indicated that the difference in BMI z score between the nutrition specialist-only category and the reference category was significant at 3 to <6 months, 6 months to <1 year, and 1-year to 2-year time points (P=0.01, P=0.05, and P=0.01, respectively). There were smaller increases in BMI over time for the nutrition specialist-only provider category compared with reference categories, and this difference was significant at the 3 to <6 months and 1-year to 2-years time points (P=0.001 and P=0.05, respectively). There were no significant differences among provider categories for waist circumference at any time point., Conclusions: Indirect evidence indicated that pediatric weight management outcomes for BMI z score and BMI at selected time points appeared to be better when a nutrition specialist was involved in delivering care., (Copyright © 2019 Academy of Nutrition and Dietetics.
