Abstract
Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a poorly understood chronic illness with many case definitions that disagree on key symptoms, including hypersensitivities to noise and lights. The aim of the current study was to understand the prevalence rates and characteristics of these symptoms amongst people with ME/CFS and to compare them to people with another chronic illness, multiple sclerosis (MS). International datasets consisting of 2,240 people with either ME/CFS or MS have completed the DePaul Symptom Questionnaire (DSQ) and the Short Form Health Survey Questionnaire (SF-36). Hypersensitivities to noise and lights were indicated from items on the DSQ, and participants were analyzed against DSQ and SF-36 subscales through a multivariate analysis of covariance. There were significantly higher percentages of people with hypersensitivities in the ME/CFS sample compared to the MS sample. Regardless of illness, participants that exhibited both hypersensitivities reported greater symptomology than those without hypersensitivities. Healthcare providers and researchers should consider these symptoms when developing treatment plans and evaluating ME/CFS case diagnostic criteria.

Abstract
PURPOSE/OBJECTIVE(S) The AUTOFRAME platform has been previously developed for automating clinical workflows and has achieved L3 automation for patient-specific quality assurance (PSQA). The aim of this study is to further develop the platform to achieve L4 automation, which extends AUTOFRAME to operate Varian's control console (VCC) for the linear accelerator. The goal is to automate all PSQA operations outside of the treatment room. MATERIALS/METHODS The automated stages, listed in Table 1, are ranging from L0 to L5. The current study focuses on L4 automation of PSQA, which uses a 6-axis robot arm to control buttons on the VCC. The robotic arm is mounted on a custom frame that is attached onto the VCC to maintain its relative position. The arm is controlled through python scripts, which is run on a raspberry pi and communicates with the AUTOFRAME platform via the PyFlow and AutoFlow subsystems. This integration allows the robotic arm to receive commands from AutoFlow and execute them through PyFlow, activating real-time button-pressing actions. RESULTS The integrated L4 system was tested using real PSQA verification plans, which involved a minimum of 4 actions and a maximum of 9 actions on the VCC, including a couch kick that required overriding the couch position. The results showed that the 6-axis arm was able to correctly execute the action groups and guide the robotic arm to consistently press and hold each button with sufficient force and accuracy. All buttons on the VCC, including the Motion-enable, Preparing, Readying, and Delivering buttons, were correctly pushed and held according to the PSQA steps. The system successfully delivered all beams without interruption, and all beam delivery data was collected by the detector for PSQA analysis. CONCLUSION The study has further developed the AUTOFRAME platform for L4 automation of PSQA procedures can be achieved. The robotic arm is capable of pushing all required buttons, eliminating all human interactions on the VCC. When combined with previous L0-L3 automations, this will move towards full automation of PSQA procedures. Future work will focus on improving the system's flexibility, stability, and extending its operations to other QA tasks.

Abstract
PURPOSE/OBJECTIVE(S) To develop a complete, robust, adaptable and fully customizable software interface for assisting treatment planning procedures on FDA approved commercial system. This will standardize treatment planning process and provide opening interface to other third-party clinical software packages, and introduce AI inference to optimize plan without breaking current clinical planning workflow. MATERIALS/METHODS Based on our clinical planning workflow, Varian Eclipse TPS were used. The general HID interface AUTOFLOW was developed with scripting language AutoIt and includes optical character reorganization (OCR) ability. The AUTOFLOW is fully customizable and adaptable for different VMAT planning process. The planning workflow and objective constraints template defined by Northwell health, CFAM are applied. AUTOFLOW operates automatically 3 standard planning interfaces (contouring, external beam planning and optimization) of Eclipse based on information in action tables. The information in the tables, such as auxiliary structures, field set up and initial optimization parameters, can be preset according to the plan template or from other 3rd party packages. Based on Northwell CFAM clinical planning protocol, the planning starts from post-contour approval. AUTOFLOW operates Eclipse to create auxiliary structures, set up planning fields then initiate plan optimization. During the optimization, the AUTOFLOW fills the constraint parameters and monitor the objective goals achievement by OCR. The updated parameters are introduced with our developing machine learning package. The whole planning process were assisted by AUTOFLOW automatically, while the planner can intercept the planning process as need. RESULTS The general interface, AUTOFLOW was developed and applied to automatically assist the VMAT procedure in prostate cases. For each prostate case, more than 213 human HID operations on computers were removed from the plan procedure in our CFAM planning protocol. 12 prostate cases without manual interception were tested. The interface succeeds to reducing the VMAT planning time and planner still own the planning control. CONCLUSION The AUTOFLOW software interface can be used to perform VMAT planning in current commercial clinical planning system. It can automatically assist planner operation and provide standard interface to 3rd party software packages. The future works will focus on building a cohesive UI, reducing the time further by improving the prediction of optimization parameters and other treatment sites.

Abstract
BACKGROUND Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a debilitating chronic illness that impacts pediatric populations. OBJECTIVE The current study aimed to better understand adult perceptions of their experiences leading up to their diagnosis of ME/CFS. METHOD Patients provided data regarding symptoms of ME/CFS they may have experienced during childhood through a popular community blog forum, with participants interacting via blog comments in real-time and across various geographical locations. RESULTS Descriptive analyses indicated that roughly 43% of adult survey participants reported having developed ME/CFS prior to age 18. A standard content analysis of patient blog commentary revealed several themes, such as poor mental health, family pattern/history, healthy childhood preceding sick adulthood, feeling misunderstood, lack of clarity until adulthood, sharing of resources, poor school functioning, isolation/poor social supports, and coping mechanisms. CONCLUSION There are unique benefits and insights that can be used by investigators who collaborate with patient organizations as a means of better understanding ME/CFS illness severity, presentation, and lived experiences.

Abstract
The current study explored whether substance abuse recovery houses could be categorized into meaningful classes, which might be associated with house evictions as well as changes in individual-level recovery capital. A total of 602 individuals from 42 recovery homes were followed for up to 6 data collection periods over 2 years. House level latent class analyses were based on house-level data. A 3-class model fit very well (entropy 0.94) and better than a 2-class model. Class profiles examined concurrent (averaged across waves 1 and 2) house and resident-level variables (e.g., gender, race, age, employment, education). Class was then used to prospectively predict outcomes of the hazard of eviction and improvement in a recovery index over waves 3-6. One latent class representing 45% of the recovery houses had the highest density of members willing to loan, able to pay their rent, active involvement in outside chapter activities-this group of houses had the best outcomes including the lowest eviction rate and highest mean recovery factor. The two other classes had higher eviction rates, with one having the lowest density of friendship, selectivity of residents, and ability to pay rent. The other of the higher eviction-rate classes surprisingly had the highest density of friendship and advice seeking, but the lowest density of willingness to loan. These findings suggest that there are meaningful differences in types of recovery homes, and that house characteristics appear to influence recovery changes and eviction outcomes.

Abstract
Living in neighborhoods with lower incomes, lower education/occupational levels, and/or higher crime increases one’s risk of developing chronic health problems including cardiovascular disease risk factors and stroke. These cardiovascular health problems are known to contribute to cognitive decline and dementia. The purpose of this study was to determine the association of neighborhood socioeconomic resources and crime-related psychosocial hazards on stroke risk and cognition, hypothesizing that cardiovascular health would mediate any relationship between the neighborhood-level environment and cognition. The study evaluated 121 non-demented Chicago-area adults (~67 years; 40% non-Latino White) for cardiovascular health problems using the Framingham Stroke Risk Profile 10-year risk of stroke (FSRP-10). The cognitive domains that were tested included memory, executive functioning, and attention/information processing. Neighborhood socioeconomic resources were quantified at the census tract level (income, education, and occupation); crime-related psychosocial hazards were quantified at the point level. Structural equation modeling (SEM) did not show that the FSRP-10 mediated the relationship between neighborhood characteristics and domain-specific cognition. The SEM results did suggest that higher crime rates were associated with a higher FSRP-10 (β(105) = 2.38, p = 0.03) and that higher FSRP-10 is associated with reduced attention/information processing performance (β(105) = −0.04, p = 0.02) after accounting for neighborhood socioeconomic resources. Clinicians may wish to query not only individual but also neighborhood-level health when considering cognition.

Abstract
It is crucial for individuals with substance use disorders, especially those with a co-occurring mental health disorder, to access effective coping resources. We quantify coping through four domains of individual resources (self-esteem, self-efficacy, perceived social support, and hope) to examine the extent to which individuals with varying psychiatric severity can access coping-related resources. Since sex is an additionally important consideration in treatment, we also explore both sexes' access to coping-related resources. We generate a multilevel latent variable of coping resources in class structures, one for males and one for females, to measure (1) the extent individuals with varying psychiatric presentations (types, symptoms, severity) are able to access this latent resource and (2) to control for house level effects. Our variables of self-esteem, self-efficacy, perceived social support, and hope all coalesced into a latent variable, named coping resources. Furthermore, we find that psychiatric severity is negatively related to coping resources at the individual level, but function differently for males and females at the house level. Treatment guidelines should address the nuanced needs of individuals and consider individual differences, such as sex, that impact access to coping resources.

Abstract
Chronic fatigue syndrome/myalgic encephalomyelitis is a debilitating illness that greatly impacts the lives of sufferers. A cognitive behavioural model attempts to explain illness onset and continuance with a hypothesis that the illness is perpetuated by patients' irrational beliefs and avoidance behaviours. This theory underpins the promotion of cognitive behavioural therapy, a treatment that aims to change beliefs and behaviours. This article reports on a detailed review of the cognitive behavioural model. Our review finds that the model lacks high-quality evidential support, conflicts with accounts given by most patients and fails to account for accumulating biological evidence of pathological and physiological abnormalities found in patients. There is little scientific credibility in the claim that psycho-behavioural therapies are a primary treatment for this illness.

Abstract
BACKGROUND Formerly incarcerated individuals with substance use disorders encounter numerous obstacles following incarceration that threaten their sobriety. Obtaining safe and stable housing is a notoriously difficult task resulting in precarious housing that can increase the likelihood of relapse. The current study examined the relationship between substance use and 11 housing settings in a sample of 211 formerly incarcerated individuals with a history of substance abuse to identify the housing characteristics with the highest risk of use. METHODS Participants retroactively reported their alcohol and illicit drug consumption as well as their dwelling for the past 180 days using the Timeline Follow-back method. Housing settings were collapsed into four conceptually distinct categories: Regulated, Independent, Precarious, and Homeless. FINDINGS Results showed differences in alcohol and drug consumption across categories, with Regulated settings having less alcohol and substance use reported. The remaining settings with less oversight had a similar percentage of individuals endorse substance use; however, the Precarious setting was associated with the highest consumption of drug use. CONCLUSION Formerly incarcerated individuals with a history of substance use problems would likely benefit from housing with some degree of oversight and financial obligation. More resources should be funnelled into programs to help formerly incarcerated individuals with substance use disorders find housing that will facilitate abstinence during community re-entry.

Abstract
Individuals with postural orthostatic tachycardia syndrome share many symptoms with those who have chronic fatigue syndrome; one of which is severe fatigue. Previous literature found that those with chronic fatigue syndrome experience many forms of fatigue. The goal of this study was to investigate whether individuals with postural orthostatic tachycardia syndrome also experience multidimensional fatigue and whether these individuals can be clustered into subgroups based on the types of fatigue they endorse. A convenience sample of 138 participants (aged 14–29) with postural orthostatic tachycardia syndrome completed questionnaires that assessed fatigue, brain fog symptom severity, activities that improve brain fog, and brain fog-related disability. An exploratory factor analysis was conducted on the Fatigue Types Questionnaire, and a three-factor solution was produced. Factor scores were then used to cluster the patients into groups using a TwoStep cluster analysis. This resulted in two clusters, a high severity group and a low severity group. The clusters were then compared on a number of items related to symptom expression. Individuals within the more severe cluster had significantly more brain fog at the beginning and end of the survey when compared to cluster two. Those in the more severe cluster also described more activity impairment as well as more frequent, more severe, and more debilitation from postural orthostatic tachycardia syndrome and brain fog. The findings of the factor analysis suggest that patients with postural orthostatic tachycardia syndrome experience fatigue as a multidimensional construct and they also can be subgrouped based on symptom severity.

Abstract
Experiences of parents who care for sons or daughters with severe myalgic encephalomyelitis are rarely discussed within the literature. Narratives of parent-carers in Lost Voices from a Hidden Illness were analyzed using interpretative phenomenological analysis. This study aimed to give voices to those who care for individuals with myalgic encephalomyelitis and are often stigmatized and inform future research supporting parent-carers. Results included themes of identity change, guilt, feeling like outsiders, uncertainty, changing perceptions of time, coping mechanisms, and improvement/symptom management. Findings could inform the development of carer-focused interventions and provide vital information to health professionals about parent-carers' lived experience.

Abstract
Chronic fatigue syndrome (CFS) remains an incompletely characterized illness, in part due to controversy regarding its definition, biological basis and diagnosis. Biomarkers are objective measures that may lead to improvements in our understanding of CFS by providing a more coherent and consistent approach to study, diagnosis and treatment of the illness. Such metrics may allow us to distinguish between CFS subtypes - each defined by characteristic biomarkers - currently conflated under the single, heterogeneous condition of CFS. These delineations, in turn, may guide more granular, focused, and targeted treatment strategies based on more precise characterizations of the illness. Here, we review potential CFS biomarkers related to neurological and immunological components of the illness, and discuss how these biomarkers may be used to move the field of CFS forward, emphasizing clinical utility and potential routes of future research.

Abstract
The Mini-Mental State Exam (MMSE) is a brief cognitive test that assesses several cognitive domains, such as orientation, attention, concentration, memory, language, and constructional abilities. While the MMSE was found to be valid and reliable in the diagnosis of moderate dementia, its sensitivity and specificity for the diagnosis of mild dementia has been rarely examined. We assessed the specificity and sensitivity of the MMSE in a consecutive series of 44 patients with mild dementia, and a group of age-comparable normal controls. While the specificity of the MMSE for the diagnosis of mild dementia was very high (100%), the sensitivity was only 55% [20 of the 44 patients with mild dementia had an MMSE score in the normal range (≥26 points)]. On the other hand, the assessment with both the Buschke Selective Reminding and the Boston Naming tests discriminated mild Alzheimer's disease patients with normal MMSE scores from controls with a sensitivity and specificity of 64%. In conclusion, the assessment with verbal memory and naming tasks provided a significantly more sensitive measure of early dementia than the MMSE.

Abstract
Researchers have suggested that interpersonal relationships, particularly romantic relationships, may influence women's attempts at substance abuse recovery and community re-entry after criminal justice system involvement. The present paper evaluates relational and power theories to conceptualize the influence of romantic partner and romantic relationship qualities on pathways in and out of substance abuse and crime. The paper then combines these conceptualizations with a complementary empirical analysis to describe an ongoing research project that longitudinally investigates these relational and power driven factors on women's substance abuse recovery and community re-entry success among former substance abusing, recently criminally involved women. This paper is designed to encourage the integration of theory and empirical analysis by detailing how each of these concepts are operationalized and measured. Future research and clinical implications are also discussed.

Abstract
This study examined the sustainability rates of 214 self-run substance abuse recovery homes called Oxford Houses (OHs) over a six-year period. We list five factors needed to sustain an OH: affordable housing, residents following OH principles, resident income, institutional support, and community support. Results indicated a high sustainability rate (86.9%) in which 186 OHs remained open and 28 OHs closed. Reasons for houses closing (N = 14) included lack of affordable housing, which we classified as an external factor. Houses that closed because of internal factors (N = 13) included residents who were unable to adhere to OH rules, and insufficient income of residents. No house-level differences for income, sense of community, average lengths of stay, house age, or neighborhood characteristics were found between the houses that closed versus houses that remained open. Because the OH system relies on residents to sustain individual houses located in ordinary residential neighborhoods, these findings suggest that OH sustainability depends on locale, primarily access to affordable housing and adequate job opportunities for residents.

Abstract
BACKGROUND A defined diagnostic panel differentiated patients who had been diagnosed with chronic fatigue syndrome (CFS), based upon Fukuda/Carruthers criteria. This diagnostic panel identified an Epstein-Barr virus (EBV) subset of patients (6), excluding for the first time other similar "clinical" conditions such as cytomegalovirus (CMV), human herpesvirus 6 (HHV6), babesiosis, ehrlichiosis, borreliosis, Mycoplasma pneumoniae, Chlamydia pneumoniae, and adult rheumatic fever, which may be mistakenly called CFS. CFS patients were treated with valacyclovir (14.3 mg/kg q6h) for ≥ 12 months. Each patient improved, based upon the Functional Activity Appraisal: Energy Index Score Healthcare Worker Assessment (EIPS), which is a validated (FSS-9), item scale with high degree of internal consistency measured by Cronbach's alpha. METHODS Antibody to EBV viral capsid antigen (VCA) IgM, EBV Diffuse Early Antigen EA(D), and neutralizing antibodies against EBV-encoded DNA polymerase and EBV-encoded dUTPase were assayed serially approximately every three months for 13-16 months from sera obtained from patients with CFS (6) and from sera obtained from twenty patients who had no history of CFS. RESULTS Antibodies to EBV EA(D) and neutralizing antibodies against the encoded-proteins EBV DNA polymerase and deoxyuridine triphosphate nucleotidohydrolase (dUTPase) were present in the EBV subset CFS patients. Of the sera samples obtained from patients with CFS 93.9% were positive for EA(D), while 31.6% of the control patients were positive for EBV EA(D). Serum samples were positive for neutralizing antibodies against the EBV-encoded dUTPase (23/52; 44.2%) and DNA polymerase (41/52; 78.8%) in EBV subset CFS patients, but negative in sera of controls. CONCLUSIONS There is prolonged elevated antibody level against the encoded proteins EBV dUTPase and EBV DNA polymerase in a subset of CFS patients, suggesting that this antibody panel could be used to identify these patients, if these preliminary findings are corroborated by studies with a larger number of EBV subset CFS patients.

Abstract
Research on pediatric Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) is reviewed in this article. Many recent articles in this area highlight the existence of key differences between the adult and pediatric forms of the illness. This review article provides an overview of pediatric ME/ CFS, including epidemiology, diagnostic criteria, treatment, and prognosis. Challenges to the field are identified with the hope that in the future pediatric cases of ME/CFS can be more accurately diagnosed and successfully managed.

Abstract
Although evidence exists that substance abuse abstinence is enhanced when individuals in recovery are embedded in social networks that are cohesive, few studies examined the network structures underlying recovery home support systems. In two studies, we investigated the mechanisms through which social environments affect health outcomes among two samples of adult residents of recovery homes. Findings from Study 1 (n = 150) indicated that network size and the presence of relationships with other Oxford House (OH) residents both predicted future abstinence. Study 2 (n = 490) included individuals who lived in an OH residence for up to 6 months, and their personal relationship with other house residents predicted future abstinence. Implications of these findings are discussed.

Abstract
The effects of children on the process of substance use recovery for adults living in Oxford Houses is explored in two qualitative studies. Oxford Houses are self-run, community-based residential homes for small groups of adults who live together and support each other's efforts to recover from drug and/or alcohol addiction. In the first study, telephone interviews were conducted with 29 adults who were living in Oxford Houses that allowed children to live in the house with their parent. Results suggest that having children in the house supported a positive living environment for the recovery of house members. In the second study, telephone interviews were conducted with an additional 15 mothers who lived in Oxford Houses. These interviews focused on the effects of the mothers' addiction and recovery on their relationships with their children. This study found that most parents acknowledged the negative effects of their addiction on their relationship with their child and the effects of their recovery on improving those relationships.

Abstract
This study examined the properties of the Beck Depression Inventory-II (BDI-II) in a sample of 111 patients with chronic fatigue syndrome (CFS). Exploratory factor analysis identified two factors. The mean score for the Somatic-Affective factor was significantly higher than the Cognitive factor. Convergent and discriminant validity were assessed for BDI-II total score, the two factor scores, and the BDI for Primary Care (BDI-PC). The BDI-PC and Cognitive factor demonstrated superior validity. Results suggest patients endorse BDI-II somatic items that overlap with CFS symptoms at a high rate. Factor scores should be evaluated separately, or the BDI-PC should be utilized with this population.

Abstract
Hypocortisolism is a frequent finding in individuals with chronic fatigue syndrome (CFS) with other research findings implying potential dysregulation of glucocorticoid signaling. Glucocorticoid signaling is under the influence of several pathways, several of which are of interest in the study of CFS. Oxidative stress and decreased antioxidant capacity are known to disrupt the hypothalamic-pituitary-adrenal (HPA) axis (Epel et al., 2004) and the presence of histone deacetylases (HDAC) could also impact glucocorticoid signaling. The intent of this pilot study was to investigate the relationship among oxidative stress elements, select HDAC's (2/3) and glucocorticoid receptor signaling in an elderly sample with CFS. Findings suggest increased histone deacetylase activity, lower total antioxidant power, in the context of decreased plasma cortisol and increased plasma dehydroepiandrosterone concomitant with decreased expression of the encoding gene for the glucocorticoid receptor. These findings support the presence of HPA axis dysregulation in elderly individuals with CFS.

Abstract
<p>Few studies have explored issues of sensitivity and specificity for using the fatigue construct to identify patients meeting chronic fatigue syndrome (CFS) criteria. In this article, we examine the sensitivity and specificity of several fatigue scales that have attempted to define severe fatigue within CFS. Using Receiver Operating Characteristic (ROC) curve analysis, we found most scales and sub-scales had either significant specificity and/or sensitivity problems. However, the post-exertional subscale of the ME/CFS Fatigue Types Questionnaire (Jason, Jessen, et al., 2009) was the most promising in terms of specificity and sensitivity. Among the more traditional fatigue scales, Krupp, LaRocca, Muir-Nash, and Steinberg’s (1989) Fatigue Severity Scale had the best ability to differentiate CFS from healthy controls. Selecting questions, scales and cut off points to measure fatigue must be done with extreme care in order to successfully identify CFS cases.</p>

Abstract
PURPOSE All the major current case definitions for chronic fatigue syndrome (CFS) specify substantial reductions in previous levels of occupational, educational, social, or personal activities to meet criteria. Difficulties have been encountered in operationalizing 'substantial reductions.' For example, the Medical Outcomes Study Short Form-36 Health Survey (SF-36) has been used to determine whether individuals met the CFS disability criterion. However, previous methods of using the SF-36 have been prone to including people without substantial reductions in key areas of physical functioning when diagnosing CFS. This study sought to empirically identify the most appropriate SF-36 subscales for measuring substantial reductions in patients with CFS. METHOD The SF-36 was administered to two samples of patients with CFS: one recruited from tertiary care and the other a community-based sample; as well as a non-fatigued control group. Receiver operating characteristics were used to determine the optimal cutoff scores for identifying patients with CFS. RESULTS The SF-36 Role-Emotional subscale had the worst sensitivity and specificity, whereas the Vitality, Role-Physical, and Social Functioning subscales had the best sensitivity and specificity. CONCLUSION Based on the evidence from this study, the potential criteria for defining substantial reductions in functioning and diagnosing CFS is provided.

Abstract
The new diagnostic criteria for pediatric ME/CFS are structurally based on the Canadian Clinical Adult case definition, and have more required specific symptoms than the (Fukuda et al. Ann Intern Med 121:953-959, 1994) adult case definition. Physicians specializing in pediatric ME/CFS referred thirty-three pediatric patients with ME/CFS and 21 youth without the illness. Those who met ME/CFS criteria were separated into Severe and Moderate categories. Significant differences were found for symptoms within each of the six major categories: fatigue, post-exertional malaise, sleep, pain, neurocognitive difficulties, and autonomic/neuroendocrine/immune manifestations. In general, the results showed participants who met the Severe ME/CFS criteria reported the highest scores, the Moderate ME/CFS group show scores that were a little lower, and the control group evidenced the lowest scores. Findings indicate that the Pediatric Case Definition for ME/CFS can distinguish between those with this illness and controls, and between those with Severe versus Moderate manifestations of the illness.

Abstract
OBJECTIVE The energy envelope postulates that patients with Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS) will improve functioning when maintaining expended energy levels at the same level as available energy level. METHODS Estimated weekly Energy Quotients were established by dividing expended energy level by perceived energy level and multiplying by 100. Two groups of patients were identified following participation in a non-pharmacologic intervention trial. Some were able to keep expended energy close to available energy and others were not successful at this task. RESULTS Those who were able to stay within their energy envelope had significant improvements in physical functioning and fatigue severity. CONCLUSION Findings suggest that helping patients with ME/CFS maintain appropriate energy expenditures in coordination with available energy reserves can help improve functioning over time. PRACTICE IMPLICATIONS Health care professionals that treat patients with ME/CFS might incorporate strategies that help patients self-monitor and self-regulate energy expenditures.

Abstract
Severe, persisting fatigue is a prominent symptom of Myalgic Encephalomyelitis/chronic fatigue syndrome (ME/CFS), but individuals with this illness frequently report the occurrence of unique fatigue states that might be different from conventional symptoms of fatigue. The present study attempted to assess a comprehensive set of fatigue symptoms that have been commonly reported among patients with ME/CFS. A 22-item fatigue questionnaire was developed and administered to 130 persons diagnosed with ME/CFS and 251 controls. Adequate scale reliability was found. Factor analyses revealed a five-factor structure for participants with ME/CFS but only a one factor solution for the control group. The new scale was also contrasted with other more traditional scales developed to measure fatigue. Findings suggest that individuals with ME/CFS experience different types of fatigue than what are reported in the general populations.

Abstract
Individuals with myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) have little stamina and endurance, and pose a challenge for nursing professionals. The Energy Envelope Theory, which posits that maintaining expended energy levels consistent with available energy levels may reduce the frequency and severity of symptoms, is particularly useful when working with clients with ME/CFS. Anecdotal support from the client community for this theory supports its use as a management tool for ME/CFS, but little formal research has been done in this area. In this study, a daily energy quotient was established by dividing the expended energy level by the perceived energy level and multiplying by 100. It was predicted that those participants who expended energy beyond their level of perceived energy would have more severe fatigue and symptoms and lower levels of physical and mental functioning. Findings are congruent with the Energy Envelope Theory as they indicated that the daily energy quotient was related to several indices of functioning including depression, anxiety, fatigue, pain, quality of life, and disability. The overall results provide support for a strategy health care professionals can use when working with clients with ME/CFS.

Abstract
Hypocortisolism has been reported in chronic fatigue syndrome (CFS), with the significance of this finding to disease etiology unclear. This study examined cortisol levels and their relationships with symptoms in a group of 108 individuals with CFS. CFS symptoms examined included fatigue, pain, sleep difficulties, neurocognitive functioning, and psychiatric status. Alterations in cortisol levels were examined by calculation of mean daily cortisol, while temporal variation in cortisol function was examined by means of a regression slope. Additionally, deviation from expected cortisol diurnal pattern was determined via clinical judgment. Results indicated that fatigue and pain were associated with salivary cortisol levels. In particular, variance from the expected pattern of cortisol was associated with increased levels of fatigue. The implications of these findings are discussed.

Abstract
We examined the usefulness of methylphenidate (MPH) in the treatment of organic amnesia in a randomized, double-blind, placebo-controlled design. Twenty patients with amnesia due to closed head injuries (n = 10), viral encephalitis (n = 2), stroke lesions (n = 4), or surgical brain resections (n = 4) were assessed with a neuropsychological battery after the intake of MPH (10, 20, 30 or 40 mg), or placebo. We found no significant benefit of MPH for any of the cognitive tests.Copyright Lippincott-Raven Publishers

Abstract
OBJECTIVE To examine the presence of different dimensions of unawareness in patients with probable Alzheimer's disease. METHODS A consecutive series of 170 patients with probable Alzheimer's disease were assessed with the anosognosia questionnaire-dementia (AQ-D) which includes items related to cognitive deficits and behavioural problems. RESULTS A factor analysis of the AQ-D produced two factors: a "cognitive unawareness" factor, which loaded on items of memory, spatial and temporal orientation, calculation, abstract reasoning, and praxis, and a "behavioural unawareness" factor which loaded on items of irritability, selfishness, inappropriate emotional display, and instinctive disinhibition. A stepwise forward regression analysis showed significant correlations between the cognitive unawareness factor and more severe cognitive deficits, delusions, and apathy, but less depression. On the other hand, the behavioural unawareness factor correlated significantly with higher mania and pathological laughing scores. Whereas the cognitive unawareness factor showed a significant correlation with cognitive tests assessing verbal comprehension and long term memory, and was significantly associated with a longer duration of illness, no significant correlations were found between the behavioural unawareness factor and the neuropsychological tasks. CONCLUSION Unawareness of cognitive deficits and unawareness of behavioural problems may constitute independent phenomena in Alzheimer's disease. Whereas unawareness of cognitive deficits is related to the severity of intellectual impairment and the presence of delusional apathetic mood, unawareness of behavioural problems may be part of a disinhibition syndrome.

Abstract
The majority of adolescent smokers are able to purchase cigarettes even though laws prohibit the sale of cigarettes to minors (Radecki & Zdunich, 1993). The present study focused on merchant licensing, civil penalties, and monitoring of merchant behavior. Several different schedules of enforcement in the city of Chicago were evaluated to determine the optimal schedules to reduce the sale of cigarettes to minors in a major metropolitan area. Schedules of 2,4, and 6 months were effective in reducing illegal sales, from 86% to 19%, 87% to 34%, and 87% to 42%, respectively. In a control condition, illegal sales remained high (approximately 84%). Cigarette control laws that regularly enforce civil penalties for tobacco sales violations can successfully reduce minors' access to cigarettes.

Abstract
Declarative and procedural learning were assessed in patients with probable Alzheimer's Disease (AD) and major depression, patients with AD and no depression, patients with major depression but no dementia, and a group of age-comparable nondemented and nondepressed normal controls. AD patients showed significant deficits in declarative but not in procedural learning, while depressed nondemented patients showed the opposite pattern (i.e., a significantly worse procedural than declarative learning). Patients with both AD and major depression showed a similar learning pattern to the AD nondepressed group (relatively preserved procedural learning but severe deficits in declarative memory). These findings provide further evidence for the independence between declarative and procedural learning, and demonstrate their different vulnerability in dementia and depressive-like states.
