Eating disorders in adolescent females with and without type 1 diabetes: cross sectional study

Abstract Objective: determine the prevalence of eating disorders in adolescent females with type 1 diabetes mellitus compared with that in their non-diabetic peers. Design: Cross sectional case-control led study. Setting: Diabetes clinics and schools in three Canadian cities. Subjects: 356 females aged 12-19 with type 1 diabetes and 1098 age matched non-diabetic controls. Main outcome measure: Eating disorders meeting Diagnostic and Statistical Manual of Mental Disorders(DSM-IV) criteria. Results: Eating disorders that met DSM-IV criteria were more prevalent in diabetic subjects (36, 10%) than in non-diabetic controls (49, 4%) (odds ratio 2.4, 95% confidence interval 1.5 to 3.7; P<0.001). Subthreshold eating disorders were also more common in those with diabetes (49, 14%) than in controls (84, 8%) (odds ratio 1.9, 95% confidence interval 1.3 to 2.8; P<0.001). Mean haemoglobin A1cconcentration was higher in diabetic subjects with an eating disorder (9.4% (1.8)) than in those without (8.6% (1.6)), P=0.04). Conclusions: DSM-IV and subthreshold eating disorders are almost twice as common in adolescent females with type 1 diabetes as in their non-diabetic peers. In diabetic subjects, eating disorders are associated with insulin omission for weight loss and impaired metabolic control.

Longitudinal Study of Depressive Symptoms in Patients With Metastatic Gastrointestinal and Lung Cancer

PURPOSE Although early intervention is increasingly advocated to prevent and relieve distress in patients with metastatic cancer, the risk factors for such symptoms and their trajectory are not well established. We therefore conducted a longitudinal study to determine the course and predictors of depressive symptoms. PATIENTS AND METHODS Patients (N = 365) with metastatic gastrointestinal or lung cancer completed measures of physical distress, self-esteem, attachment security, spiritual well-being, social support, hopelessness, and depression at baseline; physical distress, social support, hopelessness, and depression were subsequently assessed at 2-month intervals. RESULTS Of the sample, 35% reported at least mild depressive symptoms, with 16% reporting moderate to severe depressive symptoms that persisted in at least one third of such individuals. Moderate to severe depressive symptoms were almost three times more common in the final 3 months of life than > or = 1 year before death. Predictors of depressive symptoms included younger age, antidepressant use at baseline, lower self-esteem and spiritual well-being, and greater attachment anxiety, hopelessness, physical burden of illness, and proximity to death. The combination of greater physical suffering and psychosocial vulnerability put individuals at greatest risk for depression. CONCLUSION Depressive symptoms in advanced cancer patients are relatively common and may arise as a final common pathway of distress in response to psychosocial vulnerabilities, physical suffering, and proximity to death. These findings support the need for an integrated approach to address emotional and physical distress in this population and to determine whether early intervention may prevent depression at the end of life.

Eating disorders in young women with type 1 diabetes mellitus.

Research findings from the past decade regarding the association of type 1 diabetes mellitus and eating disorders are critically reviewed in this paper. Although there has been much debate regarding the specificity of this association, a recent large multisite case-controlled study demonstrated that the prevalence rates of both full syndrome and subthreshold eating disorders among adolescent and young adult women with diabetes are twice as high as in their nondiabetic peers. Further, a 4-year follow-up study showed that disordered eating behavior in young women with diabetes often persists and is associated with a threefold increase in the risk of diabetic retinopathy. These eating disturbances tend to be associated with impaired family functioning and with poor diabetes management. Health care professionals should maintain a high index of suspicion for the presence of an eating disturbance among young women with diabetes, particularly among those with persistently poor metabolic control and/or weight and shape concerns. Screening for such disturbances should begin during the prepubertal period among girls with diabetes. A brief psychoeducational intervention leads to a reduction in disturbed eating attitudes and behavior but is not sufficient to improve metabolic control. More intensive treatment approaches, which should include a family-based component, may be needed to improve metabolic control. The evaluation of these and other treatment approaches is indicated in view of the serious short- and long-term health risks associated with eating disorders in young women with diabetes.

Symptomatic distress, hopelessness, and the desire for hastened death in hospitalized cancer patients

OBJECTIVE This study evaluated the desire for hastened death (DHD) in cancer patients at varying stages of disease to determine its frequency and relationship to physical and psychological distress. METHODS Two hundred twenty-four inpatients at Princess Margaret Hospital completed questionnaires assessing pain, physical symptoms, depression, hopelessness, and DHD. RESULTS There was significant physical and psychological distress in this sample with a mean of nine physical symptoms reported by each subject. Seven percent reported moderate DHD on the Schedule of Attitudes Towards Hastened Death (SAHD) and 2% reported high DHD. Hopelessness and stage of disease were the only significant independent predictors of DHD and their interaction was associated with increased DHD. Hopelessness and, less so, depression both mediated the pathways between illness-related factors and DHD. CONCLUSIONS Findings suggest that DHD is significantly related to hopelessness and advancing disease. Assessment of this phenomenon prior to the end of life may provide opportunities for intervention.

Models of care for post-treatment follow-up of adult cancer survivors: a systematic review and quality appraisal of the evidence

PurposeThe impact of cancer and cancer treatment on the long-term health and quality of life of survivors is substantial, leading to questions about the most appropriate configuration of services and models of care for follow-up of post-primary treatment survivors.MethodsA systematic review and quality appraisal of the health literature for structure of services and models of follow-up care for post-treatment survivors was identified through a search of guideline sources and empirical databases including MEDLINE, EMBASE, PsycINFO, the Cochrane Library, CINAHL, and EBSCO from 1999 through December 2009.ResultsTen practice guidelines and nine randomized controlled trials comprised the evidence base for models of care for adult cancer survivors. Although the evidence base was rated as low quality, nurse-led and primary care physician models of follow-up care were equivalent for detecting recurrence. Consensus also suggests that cancer survivors may benefit from coordinated transition planning that includes the provision of survivorship care plans as part of standard care.ConclusionsRealignment of models of care is identified as a health system priority to meet the supportive care and surveillance needs of a burgeoning survivor population. Further research is needed to evaluate the efficacy of models of care in a broader population of cancer survivors with differing needs and risks. While the evidence is limited, there is research that may be used to guide the configuration of health care services and planning.

A couple-based intervention for patients and caregivers facing end-stage cancer: outcomes of a randomized controlled trial

We evaluated the effect of Emotionally Focused Therapy (EFT) [intervention (INT)], modified for the advanced cancer population versus standard care [control (CTL)], on marital functioning and psychosocial outcomes among distressed couples. EFT examines the ways couples process patterns of interaction, facilitating change.

A couples intervention for patients facing advanced cancer and their spouse caregivers: outcomes of a pilot study

Objective: The primary objective of this study was to evaluate the effectiveness of a couples intervention in improving marital functioning in advanced cancer patients and their spouse caregivers. A secondary objective was to determine its impact on other symptoms of psychosocial distress and its feasibility and acceptability as a clinical intervention.

Consideration of Multiple Chronic Diseases in Randomized Controlled Trials

To the Editor: The Commentary by Drs Brownell and Ludwig about limiting purchases of sugar-sweetened beverages with Supplemental Nutrition Assistance Program (SNAP) funds misses an important point. SNAP is an effective program for addressing food insecurity. It is intended to supplement resources available to families for buying food and was not designed to police the healthfulness of food purchases. Screening SNAP purchases for healthfulness is not feasible without unacceptable increases in costs. Moreover, in caloric or glycemic

Qualitative meta-synthesis of survivors’ work experiences and the development of strategies to facilitate return to work

PurposeTo review the empirical qualitative literature on cancer survivors’ experiences of the return to work process in order to develop strategies for health and vocational professionals to facilitate return to work.MethodsA rigorous systematic search of five databases was completed to identify relevant qualitative studies published between Jan 2000 and July 2013. All potentially relevant titles and abstracts were reviewed by two reviewers. For studies that met eligibility, the full-text articles were obtained and assessed for quality. The collected evidence was then synthesized using meta-ethnography methods.ResultsIn total, 39 studies met the eligibility criteria and passed the quality assessment. The synthesis of these studies demonstrated that cancer diagnosis and treatment represented a major change in individuals’ lives and often resulted in individuals having to leave full-time work, while undergoing treatment or participating in rehabilitation. Thus, many survivors wanted to return to some form of gainful or paid employment after treatment and rehabilitation. However, there was also evidence that the meaning of paid employment could change following cancer. Return to work was found to be a continuous process that involved planning and decision-making with respect to work readiness and symptom management throughout the process. Nine key factors were identified as relevant to work success. These include four related to the person (i.e., symptoms, work abilities, coping, motivation), three related to environmental supports (i.e., family, workplace, professionals), and two related to the occupation (i.e., type of work/demands, job flexibility). Finally, issues related to disclosure of one’s cancer status and cancer-related impairments were also found to be relevant to survivors’ return to work experiences.ConclusionsThis review reveals that cancer survivors experience challenges with maintaining employment and returning to work following cancer and may require the coordinated support of health and vocational professionals.Implications for Cancer SurvivorsCancer survivors need integrated support from health and vocational professionals (e.g., assistance with defining work goals, determining work readiness, determining how symptoms may impact work performance, suggesting workplace supports, and accommodations) to maintain and return to work after cancer diagnosis and treatment. These supports need to be provided throughout the recovery and rehabilitation process.

Multicenter Evaluation of an Investigational Prostate Cancer Methylation Assay

PURPOSE Prostate specific antigen tests have low specificity, which frequently results in unnecessary biopsy and typically limits screening to patients with prostate specific antigen greater than 4.0 ng/ml. We evaluated an investigational prostate cancer methylation specific polymerase chain reaction assay that detects aberrant methylation in 3 markers (GSTP1, RARbeta2 and APC) that indicate the presence of prostate cancer. MATERIALS AND METHODS The assay was evaluated in 337 post-digital rectal examination urine samples (178 cancer and 159 noncancer) collected prospectively at a total of 9 clinical sites. Samples were processed wholly or after division into equal portions. Subject prostate specific antigen was 2.0 to 10.0 ng/ml. All subjects underwent transrectal ultrasound guided needle biopsy with 6 or greater cores sampled. Detection of 1 or greater markers indicated positivity. RESULTS Methylation specific polymerase chain reaction assay performance was better in whole than in divided urine cohorts (p = 0.035). Assay AUC was 0.72 in the whole urine cohort and 0.67 in the combined population. These values were higher than those of prostate specific antigen alone using 4.0 ng/ml as the cutoff (p = 0.00 and 0.01, respectively). Moreover, the assay together with the Prostate Cancer Prevention Trial risk calculator or a standard nomogram significantly improved AUC in the whole urine cohort and the combined population vs predictive algorithms alone (p <0.05). Assay positive predictive value was 54% in whole urine cohort with prostate specific antigen 2.0 to 4.0 ng/ml and negative predictive value was 87% with prostate specific antigen 4.1 to 10.0 ng/ml. Assay positive predictive value was higher in subjects with all 3 methylation markers positive. CONCLUSIONS These data demonstrate that this investigational assay used in conjunction with current screening algorithms may potentially add value to the biopsy decision making process.
