Dietary Intake Correlated to Waist-To-Hip Ratio in Patients on Maintenance Hemodialysis.

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.

Test-Retest Reliability and Validity of the Nutrition-Specific Quality of Life Questionnaire.

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.

Use of the subjective global assessment to predict health-related quality of life in chronic kidney disease stage 5 patients on maintenance hemodialysis.

OBJECTIVE: The purpose of this study was to determine whether a subjective global assessment (SGA) score was predictive of health-related quality of life (HRQoL) in stage 5 chronic kidney disease patients on maintenance hemodialysis (MHD). DESIGN AND SETTING: This was a cross-sectional secondary data analysis of MHD patients receiving therapy 3 times a week at dialysis centers located in the United States, Canada, and New Zealand. Nutritional status was assessed using the 7-point SGA. HRQoL was determined using the Medical Outcomes Study 36-item Short Form (SF-36). RESULTS: The study sample consisted of 94 men (n = 47, 50%) and women (n = 47, 50%), with a mean age of 64.9 ± 12.9 years. The mean SGA score at the end point of the study (6 months) was 5.8 ± 1.1. Participants had a mean HRQoL physical health score of 36.5 ± 9.3 at 6 months, indicating a worse physical health state. The HRQoL mental health summary score was within the normal range (50.5 ± 11.1). After controlling for confounders in the hierarchical regression models, the SGA score significantly predicted HRQoL physical health (R(2) change = 0.124; P = .012). No association was found between the SGA score and HRQoL mental health (P = .925). CONCLUSIONS: The SGA score is a significant predictor of HRQoL physical health. Given that nutritional status impacts HRQoL and that decreased HRQoL in patients on MHD is associated with mortality, complications, and reduced compliance with treatment, using the SGA to measure nutritional status can be a tool to help identify dialysis patients with a lower HRQoL in terms of physical health.

Effect of a dietitian-managed bone algorithm on serum phosphorus level in maintenance hemodialysis patients.

OBJECTIVE: This study examined the effectiveness of a registered dietitian (RD)-managed bone metabolism algorithm compared with a non-RD (registered nurse and the nephrologist)-managed one on serum phosphorus (PO4) and related clinical outcomes (corrected serum calcium [cCa] level, intact parathyroid hormone [iPTH] level, incidence of parathyroidectomy) among in-center maintenance hemodialysis (MHD) patients. DESIGN AND SETTING: The study was an 18-month retrospective review of adult MHD patients (n = 252) at 5 outpatient dialysis centers in western Massachusetts and Connecticut before and after change in the management of a comprehensive bone metabolism treatment algorithm (intravenous vitamin D, phosphate-binding medication, calcimimetic) from non-RD to RD. Calendar-matched timepoints representing 3-month averages during the non-RD- and RD-managed periods of the same algorithm were used for analyses. Comparisons of outcomes at non-RD-managed timepoint 2 (February 2009-April 2009) and RD-managed timepoint 6 (February 2010-April 2010) were performed considering potential demographic and clinical confounders. RESULTS: On average, serum PO4 level was lower during the RD-managed timepoint 6 (5.17 ± 1.23 mg/dL; mean ± standard deviation) compared with non-RD-managed timepoint 2 (5.23 ± 1.24 mg/dL), although the difference between these calendar-matched timepoints was not statistically significant (F = .108, P = .74) after controlling for age, dietary intake (equilibrated normalized protein catabolic rate), and dialysis adequacy (equilibrated Kdrt/V). Mean cCa at RD-managed timepoint 6 (8.76 ± 0.65 mg/dL) was not significantly different from non-RD-managed timepoint 2 (8.79 ± 0.74), and the difference between serum iPTH level at timepoint 6 (363.0 ± 296.8 pg/mL) compared with timepoint 2 (319.8 ± 251.5 pg/mL) was nonsignificant (F = .650, P = .42) after controlling for age. There were fewer parathyroidectomies during the RD-managed period (0.8%) compared with the non-RD-managed period (1.6%). CONCLUSIONS: RDs may be equally effective as non-RDs in bone metabolism algorithm management with respect to serum PO4, cCa, and iPTH control in MHD patients. Further research is needed to prospectively evaluate the effect of RD management on these bone mineral outcomes.

Sugar-sweetened beverage purchases and intake at event arenas with and without a portion size cap.

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.

Assessment of the Diversity and Inclusion Culture in a Physician Assistant Program.

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.

Exploring physical therapy students' experience of peer learning in a student-run clinic.

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, 1st-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 2nd-year students.

A Knowledge Translation Intervention Designed and Implemented by a Knowledge Broker Improved Documented Use of Gait Speed: A Mixed-Methods Study.

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.

Self-Reported Disability in Persons With HIV-Related Neuropathy Is Mediated by Pain Interference and Depression.

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.

A knowledge translation intervention designed using audit and feedback and the Theoretical Domains Framework for physical therapists working in inpatient rehabilitation: A case report.

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.

Reliability and Validity of the HIV Disability Questionnaire (HDQ) with Adults Living with HIV in the United States.

OBJECTIVES: To assess measurement properties of the HIV Disability Questionnaire (HDQ) among adults with HIV in the United States. METHODS: We administered the HDQ, World Health Organization Disability Assessment Schedule II (WHODAS 2.0), and a demographic questionnaire. For internal consistency reliability, we calculated Cronbach α and Kuder-Richardson-20 (KR-20) statistics for disability and episodic scores, respectively (≥0.80 acceptable). For test-retest reliability, we calculated intraclass correlation coefficients (>0.8 acceptable). For construct validity, we tested 15 a priori hypotheses assessing correlations between HDQ and WHODAS 2.0 scores. RESULTS: Of the 128 participants, the majority were males (68%), median age 51 years, taking antiretroviral therapy (96%). Cronbach α ranged from 0.88 (social inclusion) to 0.93 (uncertainty). The KR-20 ranged from 0.86 (cognitive) to 0.96 (uncertainty). Intraclass correlation coefficients ranged from 0.88 (physical, cognitive, social inclusion) to 0.92 (mental-emotional). Of the 15 hypotheses, 13 (87%) were confirmed. CONCLUSIONS: The HDQ demonstrates internal consistency reliability, test-retest reliability, and construct validity when administered to a sample of adults with HIV in the United States.

Functional Limitations and Disability in Persons Living with HIV in South Africa and United States: Similarities and Differences.

Persons living with HIV (PLHIV) may experience disability. We compared disability among PLHIV in the United States and South Africa and investigated associations with health and demographic characteristics. Secondary analysis of cross-sectional data using medical records and questionnaires including the World Health Organization Disability Assessment Schedule (WHO-DAS) 2.0 12-item version (range: 0-36, with higher scores indicative of more severe disability). Between-country differences for the presence of disability were assessed with logistic regression and differences in severity using multiple regression. Eighty-six percent of US participants reported disability, compared to 51.3% in South Africa. The mean WHO-DAS score was higher in the United States (12.09 ± 6.96) compared to South Africa (8.3 ± 6.27). Participants with muscle pain, depression, or more years since HIV diagnosis were more likely to report disability. Being female or depressed was associated with more severity. Being adherent to anti-retroviral therapy (ART) and employed were associated with less severity. Because muscle pain and depression were predictive factors for disability, treatment of those problems may help mitigate disability in PLHIV.

Integrative (epi) Genomic Analysis to Predict Response to Androgen-Deprivation Therapy in Prostate Cancer.

Therapeutic resistance is a central problem in clinical oncology. We have developed a systematic genome-wide computational methodology to allow prioritization of patients with favorable and poor therapeutic response. Our method, which integrates DNA methylation and mRNA expression data, uncovered a panel of 5 differentially methylated sites, which explain expression changes in their site-harboring genes, and demonstrated their ability to predict primary resistance to androgen-deprivation therapy (ADT) in the TCGA prostate cancer patient cohort (hazard ratio = 4.37). Furthermore, this panel was able to accurately predict response to ADT across independent prostate cancer cohorts and demonstrated that it was not affected by Gleason, age, or therapy subtypes. We propose that this panel could be utilized to prioritize patients who would benefit from ADT and patients at risk of resistance that should be offered an alternative regimen. Such approach holds a long-term objective to build an adaptable accurate platform for precision therapeutics.

Managing Complexity in Evidence Analysis: A Worked Example in Pediatric Weight Management.

Nutrition interventions are often complex and multicomponent. Typical approaches to meta-analyses that focus on individual causal relationships to provide guideline recommendations are not sufficient to capture this complexity. The objective of this study is to describe the method of meta-analysis used for the Pediatric Weight Management (PWM) Guidelines update and provide a worked example that can be applied in other areas of dietetics practice. The effects of PWM interventions were examined for body mass index (BMI), body mass index z-score (BMIZ), and waist circumference at four different time periods. For intervention-level effects, intervention types were identified empirically using multiple correspondence analysis paired with cluster analysis. Pooled effects of identified types were examined using random effects meta-analysis models. Differences in effects among types were examined using meta-regression. Context-level effects are examined using qualitative comparative analysis. Three distinct types (or families) of PWM interventions were identified: medical nutrition, behavioral, and missing components. Medical nutrition and behavioral types showed statistically significant improvements in BMIZ across all time points. Results were less consistent for BMI and waist circumference, although four distinct patterns of weight status change were identified. These varied by intervention type as well as outcome measure. Meta-regression indicated statistically significant differences between the medical nutrition and behavioral types vs the missing component type for both BMIZ and BMI, although the pattern varied by time period and intervention type. Qualitative comparative analysis identified distinct configurations of context characteristics at each time point that were consistent with positive outcomes among the intervention types. Although analysis of individual causal relationships is invaluable, this approach is inadequate to capture the complexity of dietetics practice. An alternative approach that integrates intervention-level with context-level meta-analyses may provide deeper understanding in the development of practice guidelines.

The Relationships Between Physical Activity and Cardiometabolic Risk Factors Among Women Participating in a University-Based Worksite Wellness Program.

OBJECTIVE: Associations between changes in physical activity (PA) and cardiometabolic risk factors among women with overweight/obesity enrolled in a university-based worksite wellness program (WWP) were examined. METHODS: Data from 173 women who completed a 26-week WWP were analyzed retrospectively. Participants completed diet and PA assessments and received client-centered diet/lifestyle counseling at baseline, and 12 and 26 weeks thereafter. Anthropometrics, blood pressure, and total cholesterol were measured; PA was self-reported using the International Physical Activity Questionnaire-short form at each visit. RESULTS: Significant improvements in anthropometrics (P < 0.001), blood pressure (P < 0.001), total cholesterol (P = 0.014), and PA (P = 0.007) were found at 26 weeks. In adjusted linear regression models, a 10 metabolic-equivalent-minute increase in PA was associated with 0.01% corresponding decreases in weight and waist circumference. CONCLUSION: Among women who completed this WWP, increased PA was associated with reductions in anthropometric measures.

The Effectiveness of Computer-Assisted Instruction to Teach Physical Examination to Students and Trainees in the Health Sciences Professions: A Systematic Review and Meta-Analysis.

PURPOSE: To explore knowledge and skill acquisition outcomes related to learning physical examination (PE) through computer-assisted instruction (CAI) compared with a face-to-face (F2F) approach. METHOD: A systematic literature review and meta-analysis published between January 2001 and December 2016 was conducted. Databases searched included Medline, Cochrane, CINAHL, ERIC, Ebsco, Scopus, and Web of Science. Studies were synthesized by study design, intervention, and outcomes. Statistical analyses included DerSimonian-Laird random-effects model. RESULTS: In total, 7 studies were included in the review, and 5 in the meta-analysis. There were no statistically significant differences for knowledge (mean difference [MD] = 5.39, 95% confidence interval [CI]: -2.05 to 12.84) or skill acquisition (MD = 0.35, 95% CI: -5.30 to 6.01). CONCLUSIONS: The evidence does not suggest a strong consistent preference for either CAI or F2F instruction to teach students/trainees PE. Further research is needed to identify conditions which examine knowledge and skill acquisition outcomes that favor one mode of instruction over the other.

Research Priorities for Studies Linking Intake of Low-Calorie Sweeteners and Potentially Related Health Outcomes: Research Methodology and Study Design.

Background: In a world of finite research funding, efforts to prioritize future research topics are increasingly necessary. Objective: The aim of this study was to identify and prioritize the direction of future research in the broad area of low-calorie sweetener (LCS) intake and potentially related health outcomes by using a novel method that incorporates evidence mapping in the Agency for Healthcare Research and Quality's Future Research Needs (FRN) process. Methods: A diverse expert stakeholder panel was convened and engaged to identify research gaps and prioritize future research needs. An independent research team hosted a number of interactive webinars and elicited feedback through surveys and individual interviews with the stakeholder panel, which included policymakers, lay audience members, health providers, a research funder, individuals with food industry experience, and researchers of several different specialties. Results: The stakeholder panel generated and ranked a list of 18 FRN questions across 5 broad research areas. Overall, stakeholder panel members unanimously agreed that the research questions that will have the largest public health impact are those that address outcomes related to body weight, appetite, and dietary intake. Although the LCSs included in this FRN project have all been Generally Recognized as Safe by the FDA or approved as food additives, the recurrent concerns and confusions with regard to the "safety" of LCSs by consumers underscore the importance of communicating the science to the general public. Conclusion: Our project provides evidence that engaging a diverse expert stakeholder panel is an effective method of translating gaps in nutrition research into prioritized areas of future research.

Quality of life and self-reported lower extremity function in adults with HIV-related distal sensory polyneuropathy.

BACKGROUND: Distal sensory polyneuropathy (DSP) is a common complication of HIV disease. Its effects on quality of life (QOL) and function have not been well described. OBJECTIVE: The study objectives were: (1) to compare QOL and lower extremity function in people with HIV-related DSP and people with HIV disease who do not have DSP, (2) to determine the extent to which function predicts QOL, (3) to evaluate the agreement of 2 function scales, and (4) to describe the use of pain management resources. DESIGN: This was a cross-sectional survey study with predictive modeling and measurement tool concordant validation. METHODS: A demographic questionnaire, the Medical Outcomes Study HIV Health Survey, the Lower Extremity Functional Scale (LEFS), the Lower Limb Functional Index (LLFI), and a review of medical records were used. General linear modeling was used to assess group differences in QOL and the relationship between function and QOL. Bland-Altman procedures were used to assess the agreement of the LEFS and the LLFI. RESULTS: Usable data for analyses were available for 82 of the 94 participants enrolled. The 67% of participants who reported DSP symptoms tended to be older, had HIV disease longer, and were more likely to receive disability benefits. Participants without DSP had better LLFI, LEFS, and physical health summary scores. In multivariate models, lower limb function predicted physical and mental health summary scores. The LLFI identified participants with a lower level of function more often than the LEFS. Participants with DSP were more likely to use medical treatment, physical therapy, and complementary or alternative treatments. LIMITATIONS: A sample of convenience was used; the sample size resulted in a low power for the mental health summary score of the Medical Outcomes Study HIV Health Survey. CONCLUSIONS: Quality of life and function were more impaired in participants with HIV disease and DSP. The LLFI was more likely to capture limitations in function than the LEFS. Participants with DSP reported more frequent use of pain management resources.
