Abstract
The mechanisms of fatigue in the group of people with non-alcoholic fatty liver disease and non-alcoholic steatohepatitis are protean. The liver is central in the pathogenesis of fatigue because it uniquely regulates much of the storage, release and production of substrate for energy generation. It is exquisitely sensitive to the feedback controlling the uptake and release of these energy generation substrates. Metabolic contributors to fatigue, beginning with the uptake of substrate from the gut, the passage through the portal system to hepatic storage and release of energy to target organs (muscle and brain) are central to understanding fatigue in patients with chronic liver disease. Inflammation either causing or resulting from chronic liver disease contributes to fatigue, although inflammation has not been demonstrated to be causal. It is this unique combination of factors, the nexus of metabolic abnormality and the inflammatory burden of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis that creates pathways to different types of fatigue. Many use the terms central and peripheral fatigue. Central fatigue is characterized by a lack of self-motivation and can manifest both in physical and mental activities. Peripheral fatigue is classically manifested by neuromuscular dysfunction and muscle weakness. Therefore, the distinction is often seen as a difference between intention (central fatigue) versus ability (peripheral fatigue). New approaches to measuring fatigue include the use of objective measures as well as patient reported outcomes. These measures have improved the precision with which we are able to describe fatigue. The measures of fatigue severity and its impact on usual daily routines in this population have also been improved, and they are more generally accepted as reliable and sensitive. Several approaches to evaluating fatigue and developing endpoints for treatment have relied of biosignatures associated with fatigue. These have been used singly or in combination and include: physical performance measures, cognitive performance measures, mood/behavioral measures, brain imaging and serological measures. Treatment with non-pharmacological agents have been shown to be effective in symptom reduction, whereas pharmacological agents have not been shown effective.

Abstract
INTRODUCTION Understanding the impact of disease on function and improving functional outcomes is an important goal of rehabilitation. This scoping review analyzes 25 years of published traumatic brain injury (TBI) clinical rehabilitation research (CRR) to determine the frequency with which function is a research goal. METHODS The review protocol was prepared by experienced clinical researchers in the field. We used these search terms: "moderate traumatic brain injury" and "severe traumatic brain injury" and "functional outcomes"; and "rehabilitation" and "educational outcomes" or "cognition" or "community roles" or "community integration" "behavior" or "neuropsychology" or "quality of life", or "vocational outcomes" or "work" or "return to work". Publications from January 1, 1990-December 31, 2016 were included. RESULTS 1,815 articles met initial criteria, of which 202 were intervention studies, 84 were randomized controlled trials and 353 prospective non-intervention studies. The combination of intervention and prospective non-intervention studies (n = 555) were analyzed for the kind of measurement tools used. Impairment measures (60%) and symptom measures (43%) either singly or in combination were most frequently used. Measures of function were employed in fewer than 30%. For single outcomes, 95 publications used impairment measures, 60 used symptoms and only18 used function. There were 117 studies that used neurocognitive measures. Participation/societal integration evaluation tools were used for community integration(n = 77) employment (n = 50) and independent living status (n = 37). DISCUSSION This scoping review identifies a need for additional types of clinical research in the field of TBI CRR. Much of the research is aimed at mitigating impairment and controlling symptoms rather than promoting function. Future efforts by the CRR community studying TBI should address this need.

Abstract
Before the patient protection and affordable care act (ACA), young adults (20 to 34) had the highest uninsured rates in the United States (US) and frequently sought care in emergency departments (EDs).We aimed to determine if there was a measurable effect of expanded coverage, specifically the dependent coverage provision and Medicaid expansion, on the payer mix of young adults in EDs.We performed a retrospective cross-sectional study of ED utilization among young adults across the US using the national hospital ambulatory medical care survey (NHAMCS) (2005-2015).We examined the effect of health reform changes on the prevalence and odds of having an insurance type among ED utilizers (19-30) in 3 time periods (2005-2010), (2011-2013), and (2014-2015). Additionally, we compared the national and ED payer mix proportions among 19 to 25 and 26 to 30-year-olds.Our results indicate significant proportional changes in the national and ED payer mix relative to a pre-ACA time period. The 2 greatest changes to the national payer mix were the reduction in the proportion of uninsured/self-payers and the increase in the proportion covered by Medicaid. Furthermore, the dependent coverage provision was effective in increasing the proportion of those (19-25) utilizing private insurance coverage. Lastly, there is now a lower proportion of uninsured young adults in the ED, and an increased proportion of those covered by Medicaid.The change in payer mix among young adults has potential long-term consequences for the provision of emergency department services in the U.S.

Abstract
People who have cancer diagnoses often need care throughout their lives through all stages of their illness. These stages include diagnosis, primary treatment, survivorship, and end of life. The management of people with cancer, now a common and chronic illness with long-term survival improving, is complex, challenging, and rapidly changing. Rehabilitation for people with cancer diagnoses is a new specialty and is charged with providing care throughout the trajectory of illness and wellness to maximize potential for function and mitigate disability. Rehabilitation interventions include the application of physical and occupational therapeutics, speech and language interventions, and physical medicine in order to help patients reach their individual goals and to promote life satisfaction. The Department of Rehabilitation in the Clinical Center of the National Institutes of Health has pioneered this field through research and clinical care models over the past 40 years. Staff of this department has supported clinical research investigators at the National Institutes of Health in their exploration of new treatments using chemotherapies, surgery, radiation, and psychosocial interventions. They have also engaged in research specific to rehabilitation to devise and improve functional outcome measures, design exercise interventions, devise orthotics, and prosthetic devices for adaptation to functional loss. Collectively, the staff has published widely in oncology textbooks and professional journals in order to share findings and improve the quality of cancer rehabilitation treatment across the continuum of care.

Abstract
Fatigue is a common symptom. Diagnosis is difficult. Fatigue is often a complex symptom. In the recent years, fatigue has gained considerable amount of attention. It has 2 major types, central and peripheral, which may occur together or alone. Although fatigue has many strong relations with depression and sleep disorders, it is a separate entity. For the diagnosis of fatigue, self-reports and patient-reported outcomes are highly valuable tools because these methods can reflect patients' perceptions. Treating the underlying disease with newly developed direct-acting antivirals often improves the perceived fatigue. Healthy lifestyle changes are the cornerstone of the treatment.

Abstract
This manuscript assesses whether the Veterans Administration Rating System (VADR) correlates with self-reported activities of daily living (ADL) used in the National Survey of Veterans and likelihood of employment. Veterans' disability benefits are determined based on a single-index standardized rating scheme, measured at time of discharge. The primary aim of this study was to assess how this single-index rating of disability for veterans compares to multidimensional measures of disability (ADL and instrumental activities of daily living [IADL]). The relationship between disability ratings and labor market outcomes such as job search behavior and the likelihood of being employed was assessed. Successful labor market reintegration requires both physical/mental well-being, we examined the extent that VADR can capture the relationship between job market behavior and measures of mental/physical health. Kernel regression estimates were obtained of the likelihood of working/looking for work. Mean numbers of IADL and ADL difficulties and medical conditions were positively associated with VADR (p-trend < 0.001). An inverse relationship was observed with VADR and predicted probability of working (p-trend < 0.001). The combination of >4 ADL/IADL deficits and mental health diagnosis increased the likelihood of not working. The probability of not working correlated with VADR when VADR was greater than 40%.

Abstract
BACKGROUND Dry needling is an effective treatment for reducing pain associated with active myofascial trigger points (a-MTrPs) in the short term. The duration of the benefits of this treatment have not been fully assessed. OBJECTIVE To determine whether the benefits of dry needling (DN) of a-MTrPs are sustained 6 weeks posttreatment. DESIGN Follow-up of a prospective study. SETTING University. PARTICIPANTS A total of 45 patients (13 male and 32 female) with cervical pain >3 months and a-MTrPs in the upper trapezius who completed 3 DN treatments and who were evaluated 6 weeks posttreatment. INTERVENTIONS None. MAIN OUTCOME MEASURES Primary outcomes were changes from baseline to follow-up in scores for the verbal analogue scale (VAS), Brief Pain Inventory (BPI), and MTrP status. MTrPs were rated as active (spontaneously painful), latent (painful only on compression), and nonpalpable nodule. Responders were patients whose MTrP status changed from active to latent or nonpalpable nodule (resolved). Secondary outcomes were pain pressure threshold (PPT), Profile of Mood States, Oswestry Disability Index (ODI), MOS 36-Item Short-Form Health Survey (SF-36), and cervical range of motion. RESULTS Pain measures remained significantly improved 6 weeks posttreatment (P < .003), as did the SF-36 physical functioning score (0.01) and ODI (P = .002). Side bending and PPT for subjects with unilateral MTrPs had sustained improvement (P = .002). The number of subjects with sustained MTrP response at 6 weeks was significant (P < .001). Comparing responders to nonresponders, the changes in VAS and BPI were statistically significant (P = .006, P = .03) but the change in PPT was not. Patients with higher baseline VAS scores had a higher risk of not responding to DN; those with a greater drop in VAS score from baseline had a higher probability of sustained response. A 1-unit decrease in VAS at baseline resulted in a 6.3-fold increase in the odds of being a responder versus a nonresponder (P = .008). CONCLUSIONS In this study, there was sustained reduction of pain scores after completion of DN, which is more likely with a greater drop in VAS score. Patients with higher baseline VAS scores are less likely to respond to DN. Early intervention toward significant pain reduction is likely to be associated with sustained clinical response. LEVEL OF EVIDENCE IV.

Abstract
There is a need for additional strategies for performing systematic reviews (SRs) to improve translation of findings into practice and to influence health policy. SRs critically appraise research methodology and determine level of evidence of research findings. The standard type of SR identifies randomized controlled trials (RCTs) as providing the most valid data and highest level of evidence. RCTs are not among the most frequently used research design in disability and health research. RCTs usually measure impairments for the primary research outcome rather than improved function, participation or societal integration. It forces a choice between "validity" and "utility/relevance." Other approaches have effectively been used to assess the validity of alternative research designs, whose outcomes focus on function and patient-reported outcomes. We propose that utilizing existing evaluation tools that measure knowledge, dissemination and utility of findings, may help improve the translation of findings into practice and health policy.

Abstract
OBJECTIVES To compare a mechanical heterogeneity index derived from ultrasound vibration elastography with physical findings before and after dry-needling treatment of spontaneously painful active myofascial trigger points in the upper trapezius muscle. METHODS Forty-eight patients with chronic myofascial pain enrolled in a prospective interventional trial of 3 weekly dry-needling treatments for active myofascial trigger points. Trigger points were evaluated at baseline and at treatment completion using palpation, the pressure-pain threshold, and the mechanical heterogeneity index. Thirty patients were reevaluated at 8 weeks. Trigger points that "responded" changed to tissue that was no longer spontaneously painful, with or without the presence of a palpable nodule. Trigger points that "resolved" changed to tissue without a palpable nodule. The mechanical heterogeneity index was defined as the proportion of the upper trapezius muscle that appeared mechanically stiffer on elastography. Statistical significance for comparisons was determined at P < .05. RESULTS Following 3 dry needle treatments, the mechanical heterogeneity index decreased significantly for the 38 myofascial trigger points (79% of 48) that responded to treatment. Among these, the baseline mechanical heterogeneity index was significantly lower for the 13 trigger points (27% of 38) that resolved, but the decrease after 3 dry needle treatments did not reach significance. The pressure-pain threshold improved significantly for both groups. At 8 weeks, the mechanical heterogeneity index decreased significantly for the 22 trigger points (73% of 30) that responded and for the 10 (45% of 22) that resolved. The pressure-pain threshold improvement was significant for trigger points that responded but did not reach significance for resolved trigger points. CONCLUSIONS The mechanical heterogeneity index identifies changes in muscle tissue properties that correlate with changes in the myofascial trigger point status after dry needling.

Abstract
The intent of this article is to discuss the evolving role of the myofascial trigger point (MTrP) in myofascial pain syndrome (MPS) from both a historical and scientific perspective. MTrPs are hard, discrete, palpable nodules in a taut band of skeletal muscle that may be spontaneously painful (i.e., active) or painful only on compression (i.e., latent). MPS is a term used to describe a pain condition that can be acute or, more commonly, chronic and involves the muscle and its surrounding connective tissue (e.g. fascia). According to Travell and Simons, MTrPs are central to the syndrome-but are they necessary? Although the clinical study of muscle pain and MTrPs has proliferated over the past two centuries, the scientific literature often seems disjointed and confusing. Unfortunately, much of the terminology, theories, concepts, and diagnostic criteria are inconsistent, incomplete, or controversial. To address these deficiencies, investigators have recently applied clinical, imaging (of skeletal muscle and brain), and biochemical analyses to systematically and objectively study the MTrP and its role in MPS. Data suggest that the soft tissue milieu around the MTrP, neurogenic inflammation, sensitization, and limbic system dysfunction may all play a role in the initiation, amplification, and perpetuation of MPS. The authors chronicle the advances that have led to the current understanding of MTrP pathophysiology and its relationship to MPS, and review the contributions of clinicians and researchers who have influenced and expanded our contemporary level of clinical knowledge and practice.

Abstract
BACKGROUND Obesity, a complex disease determined both by genetic and environmental factors, is strongly associated with NAFLD, and has been demonstrated to have a negative impact on HCV and other chronic liver diseases (CLD). RATIONALE This study assessed the association between type and location of food sources and chronic liver disease (CLD) using Geographic Information Systems (GIS). RESULTS CLD patients completed surveys [267 subjects, 56.5% female, age 55.8 ± 12.0, type of CLD: 36.5% hepatitis C (HCV), 19.9% hepatitis B (HBV), 19.9% non-alcoholic fatty liver disease (NAFLD); primary food source (PFS): 80.8% grocery store, secondary: 26.2% bulk food store, tertiary: 20.5% restaurants; fresh food (FF): 83%, pre-packaged (PP) 8.7%, already prepared (AP) 8.3%]. FF consumers had significantly fewer UEH servings/month (p = 0.030) and lived further away from convenience stores (1.69 vs. 0.95 km, p = 0.0001). Stepwise regression reveals the lowest FF consumers were NAFLD patients, subjects with UEH or restaurants and ethnic food stores as their PFS (R = 0.557, p = 0.0001). Eating already-packaged foods and utilizing restaurants or ethnic food stores as the PFS positively correlated with NAFLD (R = 0.546, p = 0.0001). CONCLUSIONS Environmental food source measures, including type and density, should be included when examining areas hyper-saturated with a variety of food options. In hyper-saturated food environments, NAFLD patients consume more prepared food and less FF. CLD patients with UEH also eat significantly more prepared food and frequent restaurants and ethnic food stores as their PFS.

Abstract
OBJECTIVE To determine whether dry needling of an active myofascial trigger point (MTrP) reduces pain and alters the status of the trigger point to either a non-spontaneously tender nodule or its resolution. DESIGN A prospective, nonrandomized, controlled, interventional clinical study. SETTING University campus. PARTICIPANTS A total of 56 subjects with neck or shoulder girdle pain of more than 3 months duration and active MTrPs were recruited from a campus-wide volunteer sample. Of these, 52 completed the study (23 male and 33 female). Their mean age was 35.8 years. INTERVENTIONS Three weekly dry needling treatments of a single active MTrP. MAIN OUTCOME MEASURES PRIMARY OUTCOMES Baseline and posttreatment evaluations of pain using a verbal analogue scale, the Brief Pain Inventory, and the status of the MTrP as determined by digital palpation. Trigger points were rated as active (spontaneously painful), latent (requiring palpation to reproduce the characteristic pain), or resolved (no palpable nodule). SECONDARY OUTCOMES Profile of Mood States, Oswestry Disability Index, and Short Form 36 scores, and cervical range of motion. RESULTS PRIMARY OUTCOMES A total of 41 subjects had a change in trigger point status from active to latent or resolved, and 11 subjects had no change (P < .001). Reduction in all pain scores was significant (P < .001). SECONDARY OUTCOMES Significant improvement in posttreatment cervical rotational asymmetry in subjects as follows: unilateral/bilateral MTrPs (P = .001 and P = 21, respectively); in pain pressure threshold in subjects with unilateral/bilateral MTrPs, (P = .006 and P = .012, respectively); improvement in the SF-36 mental health and physical functioning subscale scores (P = .019 and P = .03), respectively; and a decrease in the Oswestry Disability Index score (P = .003). CONCLUSIONS Dry needling reduces pain and changes MTrP status. Change in trigger point status is associated with a statistically and clinically significant reduction in pain. Reduction of pain is associated with improved mood, function, and level of disability.

Abstract
BACKGROUND The primary aim of this study was to assess the level of engagement in computer-based simulations of functional tasks, using a haptic device for people with chronic traumatic brain injury. The objectives were to design functional tasks using force feedback device and determine if it could measure motor performance improvement. METHODS A prospective crosssectional study was performed in a biomedical research facility. The testing environment consisted of a single, interactive, stylus-driven computer session navigating virtual scenes in 3D space. Subjects had a haptic training session (TRAIN) and then had three chances to perform each virtual task: (i) remove tools from a workbench (TOOL), (ii) compose 3 letter words (SPELL), (iii) manipulate utensils to prepare a sandwich (SAND), and (iv) tool use (TUSE). Main Outcome Measures included self-report of engagement in the activities, improved performance on simulated tasks and observer estimate as measured by time to completion or number of words completed from baseline, correlations among performance measures and self-reports of boredom, neuropsychological symptom inventory (NSI), and The Purdue Peg Motor Test (PPT). RESULTS Participants were 19 adults from the community with a 1 year history of non-penetrating traumatic brain injury (TBI) and were able to use computers. Seven had mild, 3 moderate and 9 severe TBIs. Mean score on the Boredom Proneness Scale (BPS): 107 (normal range 81-117); mean NSI:32; mean PPT 54 (normal range for assembly line workers >67). Responses to intervention: 3 (15%)subjects did not repeat all three trials of the tasks; 100% reported they were highly engaged in the interactions; 6 (30%) reported they had a high level of frustration with the tasks, but completed them with short breaks. Performance measures: Comparison of baseline to post training: TOOL time decreased by (mean) 60 sec; SPELL increased by 2.7 words; TUSE time decreased by (mean) 68 sec; and SAND time decreased by (mean) 72 sec. PPT correlated with TOOL (r=-0.65, p=0.016) and TUSE time (r=-0.6, p=0.014). SPELL correlated with Boredom score (r=0.41, p=0.08) and NSI (r=-.49, p=0.05). CONCLUSION People with chronic TBI of various ages and severity report being engaged in using haptic devices that interact with 3D virtual environments. Haptic devices are able to capture objective data that provide useful information about fine motor and cognitive performance.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is frequently concomitant with obesity. This article discusses factors that influence health and functional outcomes of people who develop NAFLD, including increased burden of illness, whole body function, performance, and perception of self-efficacy. Changes in macronutrients, amount of calories consumed, and decreased physical activity all negatively influence patient outcome. The benefits of exercise in this population are also discussed. To be effective, exercise must be performed, regularly and in conjunction with dietary and other behavioral change. Therefore, a lifelong commitment to exercise, activity, and diet are needed if NAFLD is to be successfully treated.

Abstract
Myofascial trigger points (MTrPs) are palpable, tender nodules in skeletal muscle that produce symptomatic referred pain when palpated. MTrPs are characteristic findings in myofascial pain syndrome (MPS). The role of MTrPs in the pathophysiology of MPS is unknown. Objective characterization and quantitative measurement of the properties of MTrPs can improve their localization and diagnosis, as well as lead to clinical outcome measures. MTrPs associated with soft tissue neck pain are often found in the upper trapezius muscle. We have previously demonstrated that MTrPs can be visualized using ultrasound imaging. The goal of this study was to evaluate whether texture-based image analysis can differentiate structural heterogeneity of symptomatic MTrPs and normal muscle.

Abstract
OBJECTIVE To determine whether standard evaluations of pain distinguish subjects with no pain from those with myofascial pain syndromes (MPS) and active myofascial trigger points (MTrPs) and to assess whether self-reports of mood, function, and health-related quality of life differ between these groups. DESIGN A prospective, descriptive study. SETTING University. PATIENTS Adults with and without neck pain. METHODS We evaluated adults with MPS and active (painful) MTrPs and those without pain. Subjects in the "active" (A) group had at least one active MTrP with spontaneous pain that was persistent, lasted longer than 3 months, and had characteristic pain on palpation. Subjects in the "no pain" (NP) group had no spontaneous pain. However, some of these subjects had discomfort upon MTrP palpation (latent MTrP), whereas others in the NP group had no discomfort upon palpation of nodules or had no nodules. OUTCOME MEASURES Each participant underwent range of motion measurement, a 10-point manual muscle test, and manual and algometric palpation. The latter determined the pain/pressure threshold using an algometer of 4 predetermined anatomic sites along the upper trapezius. Participants rated pain using a verbal analog scale (0-10) and completed the Brief Pain Inventory and Oswestry Disability Scale (which included a sleep subscale), the Short -Form 36 Health Survey, and the Profile of Mood States. RESULTS The A group included 24 subjects (mean age 36 years; 16 women), and the NP group included 26 subjects (mean age 26 years; 12 women). Group A subjects differed from NP subjects in the number of latent MTrPs (P = .0062), asymmetrical cervical range of motion (P = .01 for side bending and P = .002 for rotation), and in all pain reports (P < .0001), algometry (P < .03), Profile of Mood States (P < .038), Short Form 36 Health Survey (P < .01), and Oswestry Disability Scale (P < .0001). CONCLUSION A systematic musculoskeletal evaluation of people with MPS reliably distinguishes them from subjects with no pain. The 2 groups are significantly different in their physical findings and self-reports of pain, sleep disturbance, disability, health status, and mood. These findings support the view that a "local" pain syndrome has significant associations with mood, health-related quality of life, and function.

Abstract
Myofascial trigger points (MTrPs) are palpable, tender nodules in taut bands of skeletal muscle that are painful on compression. MTrPs are characteristic findings in myofascial pain syndrome (MPS). The role of MTrPs in the pathophysiology of MPS is unknown. Localization, diagnosis, and clinical outcome measures of painful MTrPs can be improved by objectively characterizing and quantitatively measuring their properties. The goal of this study was to evaluate whether ultrasound imaging and elastography can differentiate symptomatic (active) MTrPs from normal muscle. Patients with chronic (>3 months) neck pain with spontaneously painful, palpable (i.e., active) MTrPs and healthy volunteers without spontaneous pain (having palpably normal muscle tissue) were recruited for this study. The upper trapezius muscles in all subjects were imaged, and the echotexture was analyzed using entropy filtering of B-mode images. Vibration elastography was performed by vibrating the muscle externally at 100 Hz. Color Doppler variance imaging was used to quantify the regions of color deficit exhibiting low vibration amplitude. The imaging measures were compared against the clinical findings of a standardized physical exam. We found that sites with active MTrPs (n = 14) have significantly lower entropy (p < 0.05) and significantly larger nonvibrating regions (p < 0.05) during vibration elastography compared with normal, uninvolved muscle (n = 15). A combination of both entropy analysis and vibration elastography yielded 69% sensitivity and 81% specificity in discriminating active MTrPs from normal muscle. These results suggest that active MTrPs have more homogeneous texture and heterogeneous stiffness when compared with normal, unaffected muscle. Our methods enabled us to improve the imaging contrast between suspected MTrPs and surrounding muscle. Our results indicate that in subjects with chronic neck pain and active MTrPs, the abnormalities are not confined to discrete isolated nodules but instead affect the milieu of the muscle surrounding palpable MTrPs. With further refinement, ultrasound imaging can be a promising objective method for characterizing soft tissue abnormalities associated with active MTrPs and elucidating the role of MTrPs in the pathophysiology of MPS.

Abstract
PURPOSE To determine whether self-reported maximal and daily activity levels are impaired among patients with nonalcoholic fatty liver disease (NAFLD), hepatitis C (HCV) and hepatitis B (HBV). METHODS Clinicodemographic, diagnostic, self-report and standard laboratory data were obtained. Univariate, multivariate and regression analyses were performed comparing group maximal (Maximum Activity Score [MAS]) and daily activity scores (Adjusted Activity Score [AAS]), adjusted for age and gender. RESULTS Two hundred twenty-two patients completed activity-level self-reports (mean age [52.4 ± 10.0 years], BMI [28.3 ± 6.58], 31.2% NAFLD, 48.3% HCV, 20.3% HBV). On multivariate analysis, significantly higher MAS (p < 0.05) and AAS in HBV patients correlated with absence of cirrhosis, younger age, male gender (higher MAS) and lower BMI (higher AAS). Lowest activity levels were found primarily in obese patients (p < 0.009). Compared with population norms, NAFLD and HCV cohorts scored mildly disabled on MAS; the HBV cohort scored low normal. Mild disability on AAS was observed in patients with HBV; moderate disability in those with NAFLD, HCV. CONCLUSIONS All groups had significantly lower activity levels than population norms. Nonobese patients showed significantly less disability than obese patients. Patients with NAFLD and HCV are likely to have lower levels than those with HBV without cirrhosis. This presents an additional risk factor for disability and mortality. IMPLICATIONS FOR REHABILITATION • Hepatitis B (HBV), hepatitis C (HCV), and nonalcoholic fatty liver disease (NAFLD) patients had significantly lower activity levels than expected for their age and gender, as measured by the Human Activity Profile (HAP). • Overweight and normal weight chronic liver disease (CLD) patients showed significantly less disability than obese chronic liver disease patients. • Patients with NAFLD and HCV are likely to participate in low levels of activity that require fewer metabolic equivalents for completion, adding an additional risk factor for disability and mortality. • Targeting low activity level in CLD patients, and decreasing BMI below the obesity threshold, may reduce disability and risk of mortality.

Abstract
OBJECTIVES Our objectives were to develop a new, efficient, and easy-to-administer approach to ultrasound elastography and assess its ability to provide quantitative characterization of viscoelastic properties of skeletal muscle in an outpatient clinical environment. We sought to show its validity and clinical utility in assessing myofascial trigger points, which are associated with myofascial pain syndrome. METHODS Ultrasound imaging was performed while the muscle was externally vibrated at frequencies in the range of 60 to 200 Hz using a handheld vibrator. The spatial gradient of the vibration phase yielded the shear wave speed, which is related to the viscoelastic properties of tissue. The method was validated using a calibrated experimental phantom, the biceps brachii muscle in healthy volunteers (n = 6), and the upper trapezius muscle in symptomatic patients with axial neck pain (n = 13) and asymptomatic (pain-free) control participants (n = 9). RESULTS Using the experimental phantom, our method was able to quantitatively measure the shear moduli with error rates of less than 20%. The mean shear modulus ± SD in the normal biceps brachii measured 12.5 ± 3.4 kPa, within the range of published values using more sophisticated methods. Shear wave speeds in active myofascial trigger points and the surrounding muscle tissue were significantly higher than those in normal tissue at high frequency excitations (>100 Hz; P < .05). CONCLUSIONS Off-the-shelf office-based equipment can be used to quantitatively characterize skeletal muscle viscoelastic properties with estimates comparable to those using more sophisticated methods. Our preliminary results using this method indicate that patients with spontaneous neck pain and symptomatic myofascial trigger points have increased tissue heterogeneity at the trigger point site and the surrounding muscle tissue.

Abstract
At some point during or after treatment, breast cancer may be considered a chronic illness, presenting many choices for managing the disease, its adverse treatment-related effects, other medical comorbidities as well as the biobehavioral burden of having a life-threatening disease, even for individuals with potentially curable breast cancer. Health care models, such as the chronic care model, the medical home, and the shared care model, provide a context for building survivorship health care models. Goals and characteristics of recently proposed shared care models for cancer survivorship health care delivery closely align with the goals and concepts of the prospective surveillance model (PSM) proposed elsewhere in this supplement to the journal Cancer. Given these similarities, along with the growth and expansion of survivorship care models and impending mandates for delivery, there is merit to considering how implementation of the PSM can be integrated with models of survivorship care delivery. The PSM model will likely face many similar challenges and barriers that have impeded widespread dissemination of other survivorship models of care. There exist opportunities to integrate lessons learned as well as to align efforts to achieve greater impact on the shared goal of improving health outcomes for breast cancer survivors.

Abstract
Cancer-related fatigue (CRF) has been documented as 1 of the most distressing symptoms reported by breast cancer survivors. CRF affects functioning and impacts quality of life. Possible causal factors include physical conditions, affective and cognitive states, proinflammatory cytokines, and metabolic factors. Several common problems are associated with CRF in women with breast cancer, including treatment side effects, obesity, arm/upper quadrant symptoms, sleep disturbances, psychological effects, and comorbid conditions. In this article, the authors review the state of the knowledge regarding these issues and nonpharmacologic and pharmacologic interventions for CRF. Physical activity and psychosocial interventions are recommended for practice. Numerous limitations of past studies need to be considered in the design of future studies. CRF is prevalent in preoperative, postoperative, and ongoing surveillance phases. Throughout the continuum of care for women with breast cancer, clinicians must screen, further assess as indicated, and treat CRF, because it is associated with emotional distress and limits function and willingness to exercise.
