Association of anatomical features of the petrotympanic fissure and presence of foramen of Huschke with otalgia and tinnitus

The petrotympanic fissure (PTF) and foramen of Huschke (FH) are anatomical structures in the temporal bone that can connect the temporomandibular joint (TMJ) and the ear. The purpose of this retrospective study was to investigate the association between PTF morphology and otalgia and tinnitus, as well as the prevalence of the FH and otological symptoms, using cone beam computed tomography (CBCT). CBCT images from 114 patients presenting with symptoms of a temporomandibular disorder were examined retrospectively. The PTF was classified into three subtypes (open, semi-open, closed) and the presence of the FH was identified. Symptoms of otalgia and tinnitus were obtained from the patient files. The FH was observed in 12.3% of patients examined, and in 12.0% of those with otalgia and 18.9% of those with tinnitus. There was no significant association between the PTF subtypes or the presence of the FH and otalgia or tinnitus (all P > 0.05). The PTF subtype and presence of the FH alone do not appear to contribute to otalgia or tinnitus in patients with temporomandibular disorders.

Childhood-Onset Lupus Nephritis in the Childhood Arthritis and Rheumatology Research Alliance Registry: Short-Term Kidney Status and Variation in Care

OBJECTIVE

The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis.

METHODS

We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded.

RESULTS

We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers.

CONCLUSION

In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Enhancing diversity, equity, inclusion, and accessibility in eosinophilic gastrointestinal disease research: the consortium for eosinophilic gastrointestinal disease researchers' journey

In response to the social inequities that exist in health care, the NIH-funded Consortium of Eosinophilic Gastrointestinal Disease Researchers (CEGIR) recently formed a diversity committee to examine systemic racism and implicit bias in the care and research of eosinophilic gastrointestinal diseases (EGIDs). Herein, we describe our process, highlighting milestones and issues addressed since the committee's inception, which we hope will inspire other researchers to enhance diversity, equity, inclusion, and accessibility (DEIA) in their fields. Our journey began by establishing mission and vision statements to define the purpose of the committee. Regular discussion of diversity-related topics was incorporated into existing meetings and web-based materials were shared. This was followed by educational initiatives, including establishing a library of relevant publications and a speaker series to address DEIA topics. We then established a research agenda focused on the following actionable items: (1) to define what is known about the demographics of EGIDs by systematic review of population-based studies; (2) to develop a practical tool for reporting participant demographics to reduce bias in EGID literature; (3) to examine health disparities in the care of individuals with eosinophilic esophagitis who present to the emergency department with an esophageal food impaction; (4) to examine how access to a gastroenterologist affects the conclusions of published research examining the prevalence of pediatric eosinophilic esophagitis; and (5) to develop a model for examining the dimensions of diversity, and provide a framework for CEGIR's ongoing projects and data capture. In addition to promoting consciousness of DEIA, this initiative has fostered inclusivity among CEGIR members and will continue to inspire positive changes in EGID care and research.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry

BACKGROUND

Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months.

METHODS

We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed.

RESULTS

We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05).

CONCLUSION

While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Social determinants of health influence disease activity and functional disability in Polyarticular Juvenile Idiopathic Arthritis

BACKGROUND

Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry.

METHODS

In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months.

RESULTS

One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability.

CONCLUSION

High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

Implementation of a remote rapid access chest pain service during the COVID-19 pandemic

Background

Rapid Access Chest Pain Clinic (RACPC) is a vital service in many hospitals in the UK, providing early specialist input for patients with suspected coronary artery disease referred via the Emergency Department (ED) or primary care (1). When the COVID-19 pandemic forced hospitals to refine their outpatient systems (2), our Trust continued the RACPC service remotely via telephone consultations.

Purpose

To examine the long-term viability of this service, we designed a study to compare the outcomes of patients seen remotely during the pandemic to patients seen face to face.

Methods

We performed a retrospective cohort study. The remote group (n=217) were patients seen over 4 weeks in April 2020, all having telephone consultations. The control group (n=368) were patients assessed face to face in the same 4-week period in 2019. Outcomes being analysed included: mode of investigation; interventions performed; and a 12 month combined safety endpoint of ED attendance with chest pain, re-referral to cardiology and hospitalisation for cardiac issue. Subgroup analysis was performed based on typicality of symptoms defined by NICE (3).

Results

Baseline characteristics were similar between groups. In both 2019 and 2020, the largest subgroup of patients were those with non-anginal chest pain (64%, 71%). There were significant differences in investigation and management between the two cohorts (Figure 1). In 2020, a higher proportion of patients were discharged with no investigation (57% vs 23%, p<0.0001). This was driven primarily by changes in management of patients with non-anginal chest pain. There were significantly higher rates of investigation of this subgroup in 2019 by either CT Coronary Angiography (25% versus 4.5%, p<0.001) or functional testing (25% versus 6.5%, p<0.001), with a much higher rate of reassurance and discharge in 2020 (81% versus 36%, p<0.0001). More patients received coronary intervention in 2019 than in 2020 (2.4% vs 0%, p=0.02). In 2020, higher proportions of patients were commenced on medical therapy without further investigation when presenting with atypical (28% versus 1%, p<0.0001) or typical angina (63% versus 11.4%, p<0.0001) (Figure 2). There was no significant difference in the 12 month combined safety endpoint (1.3% in 2019 versus 2.3% in 2020, p=0.39), and no reported cardiac deaths.

Conclusions

During the pandemic, as expected, fewer patients were investigated for coronary artery disease, with the preference being to commence medical therapy initially. This did not have a significant effect on safety endpoints. Importantly, clinicians felt comfortable with assessing and discharging patients with non-anginal chest pain remotely in 2020. This is key to the viability of a remote RACPC model, as this subgroup forms the majority of the referrals. We suggest that RACPC is appropriate for a remote model in the long term, in view of the relatively low-risk population and clear management guidelines.

POS0134 INCREASED PREVALENCE OF LUMBAR SPINE MONOSODIUM URATE DEPOSITION AMONG GOUT PATIENTS ON DUAL-ENERGY CT

Background:

Gout affecting the spine is reported as a rare event presenting with neuropathy, spinal compression and acute back pain (1). Cases are often diagnosed by tissue confirmation of monosodium urate (MSU) deposition. The frequency of gout involving the spine asymptomatically or with milder, non-specific symptoms is likely higher than reported.

Objectives:

Using dual-energy CT (DECT), we are determining prevalence/extent of MSU deposition in the lumbosacral spines of patients with gout and tophaceous gout, compared to non-gout controls.

Methods:

We are recruiting 25 controls, 25 non-tophaceous and 25 tophaceous gout patients, 45-80 years old. Exclusion criteria include CPPD disease, RA, spondyloarthropathy or spinal malignancy. All gout subjects meet ACR gout classification criteria with entry serum urate (sU) of >6.8 mg/dL, or sU >6.0 mg/dL on ULT for <6 months. Demographics, gout history, Aberdeen back pain scale, sU, ESR, and CRP are collected. DECT of the lumbosacral spine is used to assess MSU deposition and osteoarthritic changes.

Results:

63 subjects are enrolled and analyzed to date (25 control, 23 non-tophaceous and 15 tophaceous gout). Control, non-tophaceous gout, and tophaceous gout subjects have similar mean age in years (controls 61.8±3.8, non-tophaceous 64.0±6.2, tophaceous 63.5±9.2, p=0.45), but differ in BMI (controls 28.3±6.5 kg/m2, non-tophaceous 32.1±6.7 kg/m2, tophaceous 29.1±4.3 kg/m2, p=0.01) and creatinine (controls 1.0±0.2 mg/dL, non-tophaceous 1.4±0.6 mg/dL, tophaceous 1.7±0.9 mg/dL, p=0.048). Mean sU and ESR are higher in gout subjects (sU-controls 5.3±1 mg/dL, non-tophaceous 8.3±1.4 mg/dL, tophaceous 8.4±2.0 mg/dL, p<0.05; ESR-controls 13.7±13.8 mm/h, non-tophaceous 25.2±18.7 mm/h, tophaceous 22.5±15.1 mm/h, p<0.05). Using default threshold settings for MSU visualization, greater MSU deposition is observed in the spine of gout patients (controls 2.2±1.2 cm3, non-tophaceous 4.5±4.3 cm3, tophaceous 8.5±12.5 cm3, p<0.05; Table 1). Reanalysis of several scans using narrower threshold settings to limit possible artifact confirms increased MSU signal among gout patients. Although many subjects in each group do not have excessive MSU deposition, deposition is more common in both gout groups. No subject demonstrated a frank spinal tophus.

Conclusion:

Based on preliminary results, gout patients have higher inflammatory markers and greater spinal MSU deposition than controls. Preliminary analyes with more stringent DECT threshold settings suggests these differences are not artifact, but analysis is ongoing. These data suggest that MSU deposition in the spine occurs in a subset of gout patients.

POS0298 UNDERSERVED POPULATIONS IDENTIFY BARRIERS AND PROPOSE SOLUTIONS FOR SELF-MANAGING ARTHRITIS AND CHRONIC CONDITIONS

Background:

Underserved populations, such as ethnic minorities, low-income adults, and Indigenous people living with arthritis are more likely to have lower health literacy, higher rates of multi-morbidity, and face challenges in accessing care1-3. Self-management support (SMS) can help to mitigate the impacts of living with arthritis4. However, we require a more in-depth understanding of the daily barriers underserved communities face in living with arthritis in order to develop effective SMS that can meaningfully improve well-being and quality of life.

Objectives:

The study objective was to bring together underserved people living with arthritis to identify common barriers they face in taking care of their conditions in daily life, and to identify their solutions to the identified challenges.

Methods:

A team of researchers from several universities, nurse practitioners, physicians, policy makers, an arthritis consumer-patient leader and our community partners (Multi-lingual Orientation Service Association for Immigrant Communities and the Portland Hotel Society Community Services Society) engaged in a Community-based Participatory and Concept Mapping (CM) study5-7 where participants from underserved communities identified major barriers they face in managing arthritis, agreed on key themes that emerged, and determined priorities for actions. This involved three key CM activities: 1) brainstorming ideas; 2) sorting and rating ideas; and 3) analyzing and interpreting concept maps8. Data was collected through face-to-face interviews and prioritized and interpreted in workshop settings.

Results:

Sixty-three individuals who were ethnic minorities, immigrants, refugees, low-income, over 65, and/or housing insecure and living with arthritis identified 35 common barriers and made recommendations in the areas of financial difficulties, social services, access to health services, quality of health services, lack of knowledge, and mental health. Additional funding has been sought through Community-University Engagement Support Funding to enable our community partners to prioritize the recommendations in their communities, and to develop mechanisms for implementation using already existing community structures, processes, and services.

Conclusion:

Persons living with arthritis in diverse underserved communities face significant health and social inequities, including lack of access to basic life necessities such as food, housing, employment, and safety, which creates barriers to self-managing arthritis and other chronic conditions in daily life. SMS for these communities needs to address these social and environmental barriers shaping capacity for self-management, and ultimately, quality of life and well-being.

Dark Energy Survey Year 1 Results: Cosmological Constraints from Cluster Abundances, Weak Lensing, and Galaxy Correlations

We present the first joint analysis of cluster abundances and auto or cross-correlations of three cosmic tracer fields: galaxy density, weak gravitational lensing shear, and cluster density split by optical richness. From a joint analysis (4×2pt+N) of cluster abundances, three cluster cross-correlations, and the auto correlations of the galaxy density measured from the first year data of the Dark Energy Survey, we obtain Ω_{m}=0.305_{-0.038}^{+0.055} and σ_{8}=0.783_{-0.054}^{+0.064}. This result is consistent with constraints from the DES-Y1 galaxy clustering and weak lensing two-point correlation functions for the flat νΛCDM model. Consequently, we combine cluster abundances and all two-point correlations from across all three cosmic tracer fields (6×2pt+N) and find improved constraints on cosmological parameters as well as on the cluster observable-mass scaling relation. This analysis is an important advance in both optical cluster cosmology and multiprobe analyses of upcoming wide imaging surveys.

Process and Outcome Evaluation of a Mindfulness-Based Cognitive Therapy Intervention for Cisgender and Transgender African American Women Living with HIV/AIDS

There is a need for evidence-based contextualized mental health interventions for persons living with HIV/AIDS. In the current study, the primary researcher conducted open trials with African American women living with HIV/AIDS (AAWLWHA) to examine the acceptability and feasibility of Project UPLIFT, a mindfulness-based cognitive therapy intervention that has demonstrated effectiveness in persons living with epilepsy. Women were recruited for a tele-delivered phone intervention group separated by gender identity, as well as participated in pre- and post-test assessments. Additionally, data on acceptability was collected. Both cis- and transgender women were highly satisfied with the intervention and demonstrated improvement in depressive and stress symptoms. The intervention seemed to be particularly feasible for cisgender women, though more qualitative mental health research may be warranted with transgender women. The current research has implications for the utility of mindfulness-based interventions such as UPLIFT, with AAWLWHA.

Testosterone reactivity to competition and competitive endurance in men and women

Transient shifts in testosterone occur during competition and are thought to positively influence dominance behavior aimed at enhancing social status. However, individual differences in testosterone reactivity to status contests have not been well-studied in relation to real-time expressions of competitive behavior among men and women. This research tests the association between changes in endogenous testosterone levels during competition and performance in terms of competitive endurance. Participant sex, social presence, and relative status outcomes (e.g., winning vs. losing) are tested as moderators of this relationship. In two studies, men and women (total N = 398) competed in the competitive will task (timed weight-holding) either individually or in the presence of an opponent (Study 1) or as a team with and without the presence of a competitor team (Study 2). Results showed a positive relationship between testosterone reactivity and performance for men, particularly those who won or ranked highest among their group - with increasing testosterone predicting better performance and decreasing testosterone predicting worse performance. For women, the effect only emerged among individuals who competed in dyads and lost. In Study 2, an exploratory mediation analysis revealed that individual differences in trait dominance predicted both testosterone reactivity to competition and task performance, with testosterone reactivity (moderated by sex and status outcome) partially explaining the direct relationship between dominance-related traits and behavior. Our goal was to examine testosterone reactivity in relation to real-time competitive effort and highlight the potential role of this relationship in explaining how individual differences in trait dominance produce competitive behavior.

FRI0399 COLCHICINE IS NOT EFFECTIVE FOR REDUCING OSTEOARTHRITIC HAND PAIN COMPARED TO PLACEBO: A RANDOMISED, PLACEBO-CONTROLLED TRIAL (COLAH)

Background:

Current pharmacotherapies to treat or prevent hand osteoarthritis are limited. Colchicine, an anti-inflammatory agent effective at reducing joint pain and swelling in gouty arthritis, may offer relief in hand osteoarthritis, though this has not been investigated before.1

Objectives:

To investigate the efficacy of colchicine compared to placebo on VAS pain scores over 12 weeks in adults with hand osteoarthritis in a randomised, double-blind controlled trial.

Methods:

64 community-dwelling adults with hand osteoarthritis (American College of Rheumatology criteria)2(54 females, 48-79 years) were randomised 1:1 to colchicine (0.5mg twice daily) or placebo for 12 weeks. VAS pain scores (worst affected hand) were obtained at baseline and weeks 6, 12, and after treatment withdrawal at week 16. Secondary outcome measures included grip strength, C-reactive protein (CRP) and tender and swollen joint count (TSJC). Grip strength, TSJC and CRP were obtained at baseline and week 12. Intention-to-treat analyses, adjusted for age and gender, were performed using constrained longitudinal data analysis models in Stata v16.3This study is registered with the Australia New Zealand Clinical Trials Registry, ACTRN12617001524381.

Results:

58 participants completed the study (N=27 colchicine, N=31 placebo, withdrawal rate 9%). Mean (S.D) VAS score of the affected hand at baseline was 71.4 (14.5) mm in the placebo and 65.4 (15.0) mm in the colchicine group (p = 0.11). VAS scores improved during treatment, but were comparable between groups at week 6, 12 and 16 (Table 1). There were no differences between groups at week 12 for CRP, TSJC or grip strength (Table 1). Adverse events related to study medications included nausea (n=4), diarrhoea (n=9), vomiting (n=3), bloating (n=1) and reflux (n=1).

Ethnic variations in falls and road traffic injuries resulting in hospitalisation or death in Scotland: the Scottish Health and Ethnicity Linkage Study

Objectives

To investigate ethnic differences in falls and road traffic injuries (RTIs) in Scotland.

Study design

A retrospective cohort of 4.62 million people, linking the Scottish Census 2001, with self-reported ethnicity, to hospitalisation and death records for 2001–2013.

Methods

We selected cases with International Classification of Diseases–10 diagnostic codes for falls and RTIs. Using Poisson regression, age-adjusted risk ratios (RRs, multiplied by 100 as percentages) and 95% confidence intervals (CIs) were calculated by sex for 10 ethnic groups with the White Scottish as reference. We further adjusted for country of birth and socio-economic status (SES).

Results

During about 49 million person-years, there were 275,995 hospitalisations or deaths from fall-related injuries and 43,875 from RTIs. Compared with the White Scottish, RRs for falls were higher in most White and Mixed groups, e.g., White Irish males (RR: 131; 95% CI: 122–140) and Mixed females (126; 112–143), but lower in Pakistani males (72; 64–81) and females (72; 63–82) and African females (79; 63–99). For RTIs, RRs were higher in other White British males (161; 147–176) and females (156; 138–176) and other White males (119; 104–137) and females (143; 121–169) and lower in Pakistani females (74; 57–98). The ethnic variations differed by road user type, with few cases among non-White motorcyclists and non-White female cyclists. The RRs were minimally altered by adjustment for country of birth or SES.

Conclusion

We found important ethnic variations in injuries owing to falls and RTIs, with generally lower risks in non-White groups. Culturally related differences in behaviour offer the most plausible explanation, including variations in alcohol use. The findings do not point to the need for new interventions in Scotland at present. However, as the ethnic mix of each country is unique, other countries could benefit from similar data linkage-based research.

•

Ethnic inequalities in injuries are demonstrated in Scotland based on a large sample size and a fine ethnic granularity.

•

White minority ethnic groups had the highest risks of fall-related injuries in Scotland.

•

Fall-related injuries were the least likely in the Pakistani population.

•

Ethnic differences in road traffic injuries varied by the type of road user.

•

Ethnic differences in injuries were not explained by socio-economic status or country of birth.

Psychosocial Adjustment to Age-related Macular Degeneration

This article reports on a study of the psychosocial adjustment to age-related macular degeneration of 30 elderly persons by comparing the responses of subjects with this condition to those from age- and sex-matched controls on four psychosocial scales: life satisfaction, daily hassles, social support, and self-esteem. The subjects with the condition reported significantly poorer life satisfaction and greater stress, perhaps as a result of poor social support.

Chloroform-Methanol Extraction Method for Determination of Fat in Foods: Collaborative Study

Achloroform-methanol extraction method (complete extraction of fat in 3 min) for determining fat in processed and prepared foods has been studied collaboratively. Fourteen collaborators reported single replicate fat results on 7 samples representative of various food types and 2 spiked samples by the proposed method. Each sample was accompanied by a blind duplicate. For statistical purposes, the blind duplicates were treated as paired observations, and there were 2 laboratory outliers. There was a 97.9% agreement among the results from the remaining 12 collaborators and the Associate Referee for the unfortified samples. Recoveries of 93.8 and 98.3% were obtained on fortified samples, based on results obtained from 11 collaborators. The statistical analysis of the results indicate (ranges for standard deviations were Sr = 0.083-0.528, Sb = 0.101-0.379, Sd = 8.130-0.631, for fat values ranging from 1.58 to 26.91%) that this method is adequate for quantitating the fat content in a wide variety of processed foods for nutritional labeling. The method has been adopted official first action.

Kids N Fitness: A Group-based Pediatric Weight Management Curriculum Adapted for a Clinical Care Model

BACKGROUND

The current AAP clinical practice guidelines for the management of pediatric obesity recommend a structured, comprehensive, multi-disciplinary clinical intervention. However, there is a gap in the current literature on standardized curriculums for implementation of such programs. The objective of the present study is to adapt an evidenced-based, family- centered, weekly, weight management curriculum that addresses nutritional, physical activity and behavioral topics for a clinical care model at a tertiary care children's hospital.

METHODS

The curriculum was adapted for use in six individual sessions offered monthly by a multidisciplinary team, including a health educator, physician, dietitian, physical therapist and psychologist. Each provider offered specific feedback and curriculum adaptation based on their specialty. All team members completed training with scheduled treatment fidelity monitoring during implementation. To evaluate the effectiveness of the adapted curriculum, 60 adolescents, ages 14-18 years, with overweight or obesity, and at least one family member, will complete the six month intervention. The primary outcome is mean change in zBMI and %BMIp95 at six month and 18 months. Secondary outcomes include retention, satisfaction, effect on metabolic factors and activity level.

CONCLUSION

There is a paucity of literature on utilizing a standard curriculum in clinical weight management programs. Drawing from evidenced-based curriculum to strengthen clinical care creates an opportunity to improve existing clinical programs and potentially increase access and implementation of the current treatment recommendations for this high risk population.

Determination of Moisture and Fat in Meats by Microwave and Nuclear Magnetic Resonance Analysis: Collaborative Study

Ten laboratories participated in a collaborative study to determine the total moisture and fat in raw and processed meat products by microwave drying and nuclear magnetic resonance (NMR) spectroscopy. Meat products were prepared following the AOAC Method and analyzed using CEM Corp.'s SMART Trac Moisture and Fat Analysis system. SMART Trac provides moisture results by measuring the weight loss on drying by microwave energy. The dried sample is then analyzed by NMR spectrometry for fat content. Moisture and fat results are displayed and reported by the SMART Trac as a percentage (g/100 g). Microwave drying is an AOAC-approved reference method (Method 985.14), Moisture in Meat and Poultry Products. NMR spectrometry is a secondary technique used to determine the concentration of various constituents in biological, organic, or chemical samples. The study design was based on Youden's matched pair principle for collaborative tests. For the purposes of this study, 10 laboratories each tested 10 Youden matched pairs, for a total of 20 samples. The study samples represented a range of products processed daily in plant operations. Included were raw meat samples (beef, pork, chicken, and turkey) as well as processed meats (beef hot dog, pork sausage, and ham). The total moisture content of the undiluted samples, as received for the purposes of this study, was determined by AOAC Method 950.46 and ranged from 54.03 to 74.99. The total fat content of the undiluted samples was determined by AOAC Method 960.39 and ranged from 1.00 to 29.79. Statistical analysis of study results for total moisture yielded a relative standard deviation for repeatability (RSDr) range of 0.14 to 0.95 and a relative standard deviation for reproducibility (RSDR) range of 0.26 to 0.95. Statistical analysis for total fat yielded similar RSDr and RSDR range of 0.74 to 4.08. Results for turkey had higher RSDr and RSDR values, both at 12.6, due to low fat content and possibly to the separation of the samples observed by some of the collaborators. Results demonstrate that microwave drying with NMR is a rapid, practical method providing results equivalent to AOAC Methods 950.46 (Forced Air Oven Drying) and 960.39 (Soxhlet Ether Extraction) in raw and processed meat products.
