A five-item screening version of the Eating Disorder Inventory (EDI-3)

Objective

The Eating Disorder Inventory (EDI) is used worldwide in research and treatment of eating disorders (EDs). Using the latest version (EDI-3: 91 items), we extracted the best screening items for a diagnosis of anorexia (AN) and bulimia (BN) nervosa.

Method

A patient sample of 561 women was recruited from an ED treatment centre in Denmark, and a comparison group of 878 women was randomly selected from the general population. An ED diagnosis was determined according to the Eating Disorder Examination Interview, yielding 84 AN and 202 BN patients.

Results

Only two EDI items (Cronbach's α = .79) were needed to achieve a superior screening capability of BN (sensitivity = .94, specificity = .94). An adequate screening of AN was possible by using three items (α = .71; sensitivity = .91, specificity = .86).

Discussion

The present study provides an even more economical and reliable screening of AN and BN compared with existing screening instruments. Implications for DSM-5 are also discussed.     

The combined association of depression and socioeconomic status with length of post-operative hospital stay following coronary artery bypass graft surgery: Data from a prospective cohort study

Objective

To understand the association between pre-operative depression symptoms, including cognitive and somatic symptom subtypes, and length of post-operative stay in patients undergoing coronary artery bypass graft (CABG) surgery, and the role of socioeconomic status (SES).

Methods

We measured depression symptoms using the Beck Depression Inventory (BDI) and household income in the month prior to surgery in 310 participants undergoing elective, first-time, CABG. Participants were followed-up post-operatively to assess the length of their hospital stay.

Results

We showed that greater pre-operative depression symptoms on the BDI were associated with a longer hospital stay (hazard ratio = 0.978, 95% CI 0.957–0.999, p = .043) even after controlling for covariates, with the effect being observed for cognitive symptoms of depression but not somatic symptoms. Lower SES augmented the negative effect of depression on length of stay.

Conclusions

Depression symptoms interact with socioeconomic position to affect recovery following cardiac surgery and further work is needed in order to understand the pathways of this association.     

Low serum BDNF and food intake regulation: A possible new explanation of the pathophysiology of eating disorders

Background

Several lines of evidence suggest that brain-derived neurotrophic factor (BDNF) plays an important role in weight regulation and eating behavior, and poorly balanced diets lead to a decrease in blood BDNF levels. However, studies regarding BDNF blood levels in eating disorders (ED) have yielded inconsistent results. We measured serum concentrations of BDNF and assessed behavior and cognition related to eating in ED patients and control subjects.

Methods

Forty female drug-free patients [19 with anorexia nervosa (AN), 21 with bulimia nervosa (BN)], who did not meet the diagnostic criteria for depressive disorder, and 24 age-matched normal control subjects were enrolled in the current study. We evaluated eating-related psychopathology and depressive symptoms using the Eating Disorder Inventory-2 (EDI-2), Eating Attitude Test-26 (EAT-26) and the Hamilton Depression Rating Scale (HDRS), and measured serum BDNF levels by an enzyme-linked immunosorbent assay.

Results

Compared to normal controls, serum levels of BDNF were significantly reduced in AN, but not in BN. There was a significant positive correlation between serum BDNF levels and BMI in both AN patients (r = .649, p = .003) and BN patients (r = .626, p = .002). However, no correlation between serum BDNF levels and BMI was detected in the controls. Furthermore, there was a significant negative correlation between serum BDNF levels and the oral control subscale scores of EAT in both AN patients (r = − .506, p = .027) and BN patients (r = − .511, p = .018); whereas, no correlation was detected in normal controls.

Conclusion

Our study demonstrated that individuals showing more extreme food intake regulation were those with lower serum BDNF levels. This finding is contrary to that in mice where mice with reduced BDNF levels showed aberrant eating behavior. This result suggests that BDNF is no longer functioning appropriately in ED patients, which could be an important factor in the pathophysiological of ED.     

Relationships between cognitive appraisals of adolescents with OCD and their mothers

Objective

Our aim was to investigate cognitive models of OCD via the influence of mothers’ cognitive appraisals on children's cognitions and OCD symptoms.

Method

Our sample consisted of 21 adolescents with OCD, their mothers and 27 parent–child dyads for control group without OCD. Subjects with OCD and their mothers were administered The Beck Depression Inventory (BDI), The Thought–Action Fusion Scale (TAFS), The White Bear Suppression Inventory (WBSI), The Padua Inventory-Revised (PI-R) and The Penn Inventory of Scrupulosity (PIOS).

Results

While the BDI (t = 2.18, p < 0.05) and TAF Morality (t = 2.18, p < 0.05) scores of the mothers of OCD subjects were significantly higher than the mothers of control subjects, the comparisons for the PI, TAF likelihood and PIOS scores of groups were not significant. Intradyadic correlation revealed significant relationships for PI-Rumination, PI-Checking and WBSI scales between the scores of parent and child in OCD dyads, (respectively, r = 0.49, P = 0.11; r = 0.37, P = 0.045; and r = 0.47, P = 0.014). There was no significant relationship in the control group.

Conclusion

Our results partially supported that mothers’ cognitive appraisals are associated with the cognitive appraisal of adolescents. A cognitive intradyadic interaction between mother and child might be more likely in the presence of OCD in adolescents.     

Compulsive exercise to control shape or weight in eating disorders: prevalence, associated features, and treatment outcome

Objective

The study was aimed at assessing the prevalence of compulsive exercising to control shape and weight in eating disorders (EDs) and its relationship with treatment outcome.

Method

Compulsive exercising to control shape and weight, defined according to a modified version of the Intense Exercising to Control Shape or Weight section of the Eating Disorder Examination (EDE), was assessed in 165 consecutive ED inpatients entering a protocol based on the transdiagnostic cognitive behavior theory and treatment of EDs. Baseline assessment also included anthropometry, the global EDE interview, the Beck Depression Inventory, the State-Trait Anxiety Inventory (STAI), the Eating Disorders Inventory-Perfectionism Scale, and the Temperament and Character Inventory.

Results

Of the patients, 45.5% were classified as compulsive exercisers, the prevalence being highest (80%) in restricting-type anorexia nervosa (AN), lowest in EDs not otherwise specified (31.9%), and intermediate in binge/purging AN (43.3%) and in purging-type bulimia nervosa (39.3%). Compulsive exercising to control shape and weight was independently predicted by the EDE restraint score (odds ratio, 1.32; 95% confidence interval, 1.06-1.64; P = .014) after adjustment for ED; the total amount of exercise was associated with EDE restraint, as well as with the Temperament and Character Inventory reward dependence. At follow-up, an improved EDE global score was predicted by lower baseline values, higher baseline STAI and STAI improvement, and lower amount of exercise in the last 4 weeks. Voluntary treatment discontinuation was not predicted by baseline exercise.

Discussion

Compulsive exercising to control shape and weight is a behavioral feature of restricting-type AN, associated with restraint and temperament dimensions, with influence on treatment outcome.     

Prevalence and determinants of depression in Mexican patients with Parkinson's disease

Objective

To assess the prevalence and associated factors of depression in a Mexican Parkinson's disease (PD) population.

Background

Depressive symptoms are frequent in PD and have been recognized as a major determinant of quality of life. Only two previous studies have partially addressed depression in Mexican PD patients.

Methods

One hundred forty-seven non-demented PD patients were recruited at the movement disorder specialist clinic at the National Institute of Neurology and Neurosurgery, Mexico City. The following sociodemographic variables were collected: gender, age, age at onset, disease duration and disease severity in terms of Hoehn and Yahr stage. PDQ-8, NMSQuest and Beck Depression Inventory (BDI) were applied to all participants.

Results

One hundred forty-seven patients were included (49.7% female). The mean age of the sample was 62.1 ± 11.7 years, the mean age at diagnosis was 55.8 ± 12.3 and the mean duration of the disease was 6.3 ± 5 years. A total of 49 (33.3%) patients were diagnosed with current depression. Depressed patients also scored higher in the NMSQuest even when depression/anxiety items were excluded. Differences were found in gender, UPDRS III score and HY stage, but after the logistic regression analysis was performed only the NMSQuest score and low education remained as statistically significant factors for depression in Mexican PD patients.

Conclusions

Depression prevalence in PD Mexican patients is similar to other international reports. The main associated factor was the presence of non-motor symptoms.     

Poor sleep quality and resistant hypertension

Objectives

We aimed to determine the relationship between sleep quality and treatment-resistant hypertension (RH).

Methods

In our cross-sectional cohort study, 270 consecutive essential hypertensive patients were recruited at the Outpatient Hypertension Unit, University of Pisa, Italy. The Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI-Y2) were administered to all subjects. RH was defined as office blood pressure (BP) >140/90 mmHg with three or more antihypertensive drugs or controlled BP with four or more drugs. Poor sleep quality was defined as PSQI >5, depressive symptoms as BDI >10, and trait anxiety as STAI-Y2 >40. Patients with other sleep disorders were excluded.

Results

Complete data were available for 222 patients (50.9% men; mean age, 56.6 ± 12.5 y; RH, 14.9%). Poor sleep quality had a prevalence of 38.2% in the overall population. RH was associated with poor sleep quality, increased sleep latency and reduced sleep efficiency. No significant relationship was found between RH and short sleep duration or depressive symptoms and trait anxiety. Poor sleep quality was more prevalent in resistant vs nonresistant hypertensive women (70.6% vs 40.2%; P = .02) but not in resistant vs nonresistant men (43.8% vs 29.2%; P = .24). In women poor sleep quality was an independent predictor of RH, even after adjustment for cardiovascular and psychiatric comorbidities (odds ratio [OR], 5.3 [confidence interval {CI}, 1.1–27.6), explaining 4.7% of its variance. In men age, diabetes mellitus (DM), and obesity were the only variables associated with RH.

Conclusions

Poor sleep quality is significantly associated with resistance to treatment in hypertensive women, independent of cardiovascular and psychiatric confounders.     

The relationship of Internet addiction severity with Attention Deficit Hyperactivity Disorder symptoms in Turkish University students; impact of personality traits,depression and anxiety

Aim

The aim of this study was to investigate the relationship of Internet addiction (IA) with Attention Deficit Hyperactivity Disorder (ADHD) symptoms while controlling the effect of personality traits, depression and anxiety symptoms in Turkish university students.

Methods

A total of 271 university students participated in the present study. The students were assessed through the Internet Addiction Scale (IAS), the Wender Utah Rating Short Scale (WURS-25), the Turkish version of the Adult ADHD Self-Report Scale (ASRS), the Eysenck Personality Questionnaire Revised Abbreviated Form (EPQR-A), the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI).

Results

According to IAS, participants were separated into three groups, namely, moderate/high, mild and without IA groups. The rates of groups were 19.9% (n = 54), 38.7% (n = 105) and 41.3% (n = 112), respectively. Correlation analyses revealed that the severity of IAS is positively correlated with WURS-25, ASRS (total, inattention and hyperactivity/impulsivity subscales), neuroticism personality trait, depression and anxiety scores, whereas it is negatively correlated with extraversion personality trait. Hierarchical regression analysis indicated that depression and anxiety symptoms, introversion and neuroticism personality traits and the severity of ADHD symptoms (particularly hyperactivity/impulsivity symptoms) are the predictors for IAS score, respectively.

Conclusions

The severity of ADHD symptoms has predicted the severity of IA even after controlling the effect of personality traits, depression and anxiety symptoms among Turkish university students. University students with severe ADHD symptoms, particularly hyperactivity/impulsivity symptoms may be considered as a risk group for IA.     

Eating disorder symptoms and comorbid psychopathology among male and female veterans

Objective

Eating disorder (ED) symptoms have gone mostly unexamined among veterans. The current study assessed rates of bulimia nervosa (BN) and binge eating disorder (BED) symptoms and diagnoses and their associations with common comorbidities among male and female veterans.

Method

Participants were US military veterans who screened positive for trauma histories and/or a probable Diagnostic and Statistical Manual of Mental Disorders 4th Edition (DSM-IV) posttraumatic stress disorder (PTSD) diagnosis (n= 499). Symptoms of PTSD were assessed using the Clinician-Administered PTSD Scale, and symptoms of EDs, mood, and substance use disorders were assessed using the Structured Clinical Interview for the DSM-IV.

Results

Lifetime rates of BN and BED diagnoses were comparable to civilian populations, and a considerable range of lifetime and current BN and BED symptoms were identified. In multivariate models, PTSD and depression severity were most consistently associated with BN and BED symptom severity, with depression most strongly associated with EDs for women.

Conclusions

Findings highlight the importance of screening for ED symptoms among male and female veterans, particularly those that present with PTSD and depression symptomatology. Future examinations of the temporal order of such relationships and the degree to which ED symptoms and associated symptoms impact veteran functioning are warranted.     

Association between subjective well-being and depressive symptoms in treatment-resistant schizophrenia before and after treatment with clozapine

Background

We examined the relationship between subjective well-being and depressive symptoms in patients with treatment-resistant schizophrenia before and after treatment with clozapine to contribute to the growing body of research regarding the determinants of patients' perspective of their own well-being in schizophrenia.

Methods

Forty patients with treatment-resistant schizophrenia were comprehensively evaluated for subjective well-being, schizophrenic symptoms, and depressive symptoms before and 8 weeks after the initiation of treatment with clozapine. Correlation analysis and Fisher's z-transformation statistics were performed.

Results

There were significant improvements in all Positive and Negative Syndrome Scale (PANSS) factor scores and Beck Depression Inventory (BDI) score over the treatment period (P < .05). Before clozapine administration, the subjective well-being score had significant negative correlations with the PANSS depression factor score (P < .05) and the BDI score (P < .05). After clozapine treatment, the subjective well-being score still had significant negative correlations with the PANSS depression factor score (P < .05) and the BDI score (P < .05) and no new associations emerged with treatment. Fisher's z-transformation statistics revealed that the correlations between the subjective well-being score and the depression score were not significantly different before and after clozapine treatment.

Conclusions

These results indicate that depressive symptoms are significantly associated with low subjective well-being in patients with treatment-resistant schizophrenia. The association was equally significant before and after treatment with clozapine, suggesting that the relationship does not change with clozapine treatment, even when depressive symptoms improve significantly, and that there may be a common pathophysiological basis for depressive symptoms and the subjective appraisal of well-being in schizophrenia.     

Psychometric properties of the Turkish version of the Child PTSD Symptom Scale

Objective

Psychometric properties of the Turkish version of the Child PTSD Symptom Scale (CPSS) were examined in a sample of young individuals who experienced a severe earthquake.

Method

Subjects were 479 children and adolescents recruited from schools after 18 months of Van earthquake. Mean age was 12.83 (SD ± 1.88), ranging from 8 to 18.

Results

Psychometric features were generally good for the CPSS. The original three-factor structure was replicated in this study. Internal consistency of the scale was good (ranged from α = .70 to α = .89 for total and subscale scores). The CPSS demonstrated good convergent validity with Child Post-Traumatic Stress Disorder Reaction Index scores as well as good divergent validity with the State and Trait Anxiety Inventory for Children and Child Depression Inventory. As an evidence for a good discriminant validity, the CPSS successfully distinguished high PTSD individuals from low PTSD individuals.

Conclusion

The CPSS had sound psychometric properties in a Turkish youth population.     

Self-image and suicide in a Swedish national eating disorders clinical register

Objective

Using a prospective design, to examine the relation between self-image (assessed using the Structural Analysis of Social Behavior) and suicide attempts/completions in women with anorexia nervosa-restricting type (ANR), anorexia nervosa-binge/purge type (ANBP), bulimia nervosa (BN), binge eating disorder (BED), and eating disorder not otherwise specified (EDNOS); and to assess whether these self-image variables add unique predictive value to suicide when considering other baseline predictors.

Method

Women (N = 2269) aged 12 to 45 (M = 22.1) presenting to specialist eating disorders clinics in Sweden between 2005 and 2009 were identified through the Stepwise Eating Disorders Quality Register. Data on age, body mass index, eating disorder severity (Eating Disorder Examination-Questionnaire scores), psychiatric comorbidity, global assessment of functioning, and self-image were abstracted from Stepwise and included as baseline predictors or covariates. Suicide information (prior attempt and attempt/completion after Stepwise registration) was obtained from the National Patient Register and Cause of Death Register.

Results

Prevalence of detected suicide attempts/completions over the study period was 9.2%. Negative self-image variables were associated with prior suicide attempts in ANR and EDNOS and later suicide attempts/completions in women with BN. In a stepwise Cox proportional hazards model, only low self-affirmation predicted time to suicide attempts/completions in women with BN when accounting for age and prior suicide attempt.

Conclusion

Assessing self-image might assist with identifying women with BN at elevated risk for suicide.     

Non confirmatory electroencephalography in patients meeting clinical criteria for brain death: Scenario and impact on organ donation

Objective

To describe the causes and outcome of adult patients with preserved electroencephalographic activity despite clinical findings suggesting brain death (BD), and its impact on organ donation.

Methods

Retrospective study of the clinical and electroencephalography (EEG) data of all adult patients admitted to our hospital between January 2001 and December 2011 in whom a comprehensive clinical diagnosis of BD was reached following absence of brainstem reflexes and confirmatory apnea tests, were obtained. All patients with clinical findings suggesting BD and an EEG showing brain activity were selected for the analysis. We calculated the brain death interval (BDI) as the time between the first complete clinical examination and confirmatory ancillary test, or the time between the first and second complete clinical examination for BD, in order to analyze the impact on family consent for organ donation.

Results

A complete clinical examination and EEG were diagnostic in 289 patients. In 279 (96.5%), the first EEG showed electrocerebral inactivity corroborating the clinical findings of BD. The mean BDI in this group was 4.2 ± 5.8 h (median; 1.8[1.0–3.5]). This value was significantly lower than in the group in which only two full clinical evaluations were performed (p < 0.0001). In 10 out 289 (3.5%), the first EEG showed at least some brain activity. The mean BDI in this group was 27.2 ± 13.8 h (median; 22.9 [19.1−31.2]). In two cases, a third EEG was necessary before obtaining electrocerebral inactivity. A BDI > 6 h, was positively associated with a family refusal for organ donation (p = 0.02).

Conclusions

The rate of EEGs with electrocerebral activity despite clinical findings suggesting BD was only 3.5%. It occurred most frequently with severe brainstem damage. Although in this small percentage of patients, BD diagnosis was notably delayed, in the great majority of cases the use of EEG shortened the BDI. In our series, a BD diagnosis delay >6 h negatively affected consent for organ donation.

Significance

The use of EEG can decrease the time interval for brain death diagnosis.     

Psychopathology and quality of life among patients with comorbidity between schizophrenia spectrum disorder and obsessive-compulsive disorder: no evidence for a “schizo-obsessive” subtype

Background

Epidemiological studies have found that obsessive-compulsive disorder (OCD) is estimated to occur in up to 12% of patients with schizophrenia. Furthermore, several etiopathogenic mechanisms have been postulated for understanding this co-occurrence. Whether this subgroup of “schizo-obsessive” patients may be posed as a clinical entity with a distinct psychopathological and functioning profile remains unclear.

Method

A sample of adult patients who met DSM-IV criteria for both schizophrenia/schizoaffective disorder and OCD (n = 30) was compared with a “non-OCD schizophrenic” group (n = 37) and another subset of “non-schizophrenic OCD” patients (n = 30). The Positive and Negative Syndrome Scale (PANSS), the Scale to Assess Unawareness of Mental Disorder (SUMD), the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS), the Brown Assessment of Beliefs Scale (BABS), the Clinical Global Severity scale (CGI), the Quality of Life Scale (QLS), and the Beck’s Depression Inventory (BDI) were used.

Results

We found that “schizo-obsessive” subjects did not show significant differences in any outcome measures when compared to the “non-OCD schizophrenic” group. Furthermore, statistical analyses also revealed that the “non-schizophrenic OCD” group tended to have lower severity of psychopathology as well as greater quality of life than both psychotic groups.

Conclusions

These findings indicate that comorbidity between schizophrenia/schizoaffective disorder and OCD does not comprise a distinct clinical entity, particularly when compared to “non-OCD schizophrenia” disorder. Discrepancies among previous studies may be justified by methodological divergences.     

Attachment and family functioning in patients with Internet addiction

Objective

Although the Internet is used effectively in many areas of life, some users experience problems because of over-use due to a lack of control. The diagnostic criteria for Internet addiction include disruptions in family relationships, but adequate data on the attachment styles and family functioning associated with this condition are limited. This study aimed to investigate the attachment styles and family functioning of patients with Internet addiction.

Method

The sample included 30 male patients consecutively admitted to the Bak?rköy Mental Health and Research Hospital Internet Addiction Outpatient Clinic, who were diagnosed in clinical interviews as having Internet addiction according to Young’s (1998) criteria. Thirty healthy males who were matched with the experimental group in terms of sociodemographic characteristics were included as control subjects. Both groups provided sociodemographic data and completed the Beck Depression Inventory (BDI), the Experiences in Close Relationships Questionnaire-r (ECR-r) and the Family Assessment Device (FAD).

Results

Patients with Internet addiction had higher BDI scores (P< .001) and higher attachment anxiety subscores on ECR-r (P< .001) compared with those in the control group. Patients with Internet addiction evaluated their family functioning as more negative and reported problems in every aspect addressed by the FAD. Scores on the FAD behaviour control, affective responsiveness, and problem-solving subscales (P< .05) and on the FAD communication, roles, and general functioning subscales (P< .001) were significantly higher in the patient compared with the control group.

Conclusion

Patients with Internet addiction have more anxious attachment styles as well as prominent disruptions in family functioning. Thus, it may be important to evaluate the attachment styles and family functioning of patients with Internet addiction. Indeed, comprehensive treatment approaches including other family members may make important contributions to treatment success.     

Effectiveness of mindfulness-based stress reduction and mindfulness based cognitive therapy in vascular disease: A systematic review and meta-analysis of randomised controlled trials

Objective

To determine the effectiveness of mindfulness-based stress reduction (MBSR) and mindfulness-based cognitive therapy (MBCT) on psychological and physical outcomes for people with vascular disease.

Design

Systematic review and meta-analysis of randomised controlled trials.

Data sources

AMED, CINAHL, EMBASE, British Nursing Index, Medline, Web of Science, PsycINFO, Cochrane Database of Systematic Reviews, Central, Social Sciences Citation Index, Social Policy and Practice, and HMIC from inception to January 2013.

Review methods

Articles were screened for inclusion independently by two reviewers. Data extraction and quality appraisal were performed by one reviewer and checked by a second with discrepancies resolved by discussion with a third if necessary. Random-effects meta-analyses were performed.

Results

Nine articles (from eight original randomised controlled trials) met eligibility criteria and were included in the final review. In total, 578 participants were enrolled across the trials, with participants presenting with prehypertension/hypertension (n = 3 trials), type 1 or 2 diabetes (n = 2), heart disease (n = 2) and stroke (n = 1). Meta-analyses, using standardised mean differences, showed evidence of reductions in stress (− 0.36; 95% CI − 0.67 to − 0.09; p = 0.01), depression (− 0.35; 95% CI − 0.53 to − 0.16; p = 0.003) and anxiety (− 0.50; 95% CI − 0.70 to − 0.29; p < 0.001). Effects on physical outcomes (blood pressure, albuminuria, stress hormones) were mixed.

Conclusion

Whilst populations with vascular disease appear to derive a range of psychological benefits from MBSR/MBCT intervention, the effects on physical parameters of disease are not yet established. More robust studies, with longer term follow-up, are required to ascertain full effectiveness of such intervention.     

Health-related quality of life among adolescents with eating disorders

Objective

Health-related quality of life (HRQoL) is an emerging area of research in eating disorders (EDs) that has not been examined in adolescents in detail. The aim of the current study is to investigate HRQoL in an adolescent ED sample, examining the impact of ED symptoms on HRQoL.

Methods

Sixty-seven treatment-seeking adolescents (57 females) with anorexia nervosa (AN), bulimia nervosa (BN), or eating disorder not otherwise specified (EDNOS) completed self-report measures of HRQoL and ED symptoms.

Results

Participants reported poorer HRQoL in mental health domains than in physical health domains. Disordered attitudes, binge eating, and compensatory behaviors were associated with poorer mental health HRQoL, and body dissatisfaction was associated with poorer physical health HRQoL.

Conclusion

The current study assessed HRQoL among adolescents with EDs, finding several consistencies with the literature on adults with EDs. Future research should compare adolescents and adults with EDs on HRQoL.     

Patients with insomnia and subthreshold depression show marked worsening of insomnia after discontinuation of sleep promoting medication

Objective

To investigate whether the outcome of treatment with trazodone CR in primary insomnia differs between patients with and without subthreshold depression.

Methods

14 patients (9 females, mean age 57.3 ± 13.3) with primary insomnia and increased Beck Depression Inventory (BDI) scores (> 10) and 15 sex- and age-matched patients with primary insomnia and low BDI scores (≤ 10) were treated with trazodone CR 25-150 mg/d for 3 months and followed for 1 month after discontinuation of the medication. The Athens Insomnia Scale (AIS), Sheehan Disability Scale (SDS), and Clinical Global Impression scale (CGI) were completed at baseline, after each month of treatment and after the first week of run-out phase. Additional assessment tools comprised sleep diaries, the Leeds Sleep Evaluation Questionnaire (LSEQ) and actigraphic recordings.

Results

Subjective sleep time increased by 61.5 ± 72.3 min in the group with low BDI and 60.0 ± 59.4 min in the group with increased BDI at the end of the treatment phase. The significant improvements were also observed in the AIS, CGI, LSEQ and SDS. During the run-out phase the improvement was sustained in patients with low BDI, while AIS scores, sleep latency and total sleep time deteriorated in patients with increased BDI.

Conclusions

Patients with subthreshold depression, even if the depressive symptoms do not fulfill the time criteria for depressive episode, show marked worsening of insomnia after discontinuation of sleep promoting medication.     

Clinical correlates of anhedonia in patients with Parkinson's disease

Objective

To investigate the prevalence and clinical correlates of anhedonia in patients with Parkinson's disease (PD) and to also examine the relationship between anhedonia and the QOL.

Methods

One hundred and seventeen patients with PD completed the Snaith–Hamilton Pleasure Scale (SHAPS), the State–Trait Anxiety Inventory (STAI), the Beck Depression Inventory Second Edition (BDI-II), Starkstein's Apathy Scale (AS) and a quality of life (QOL) battery. Hoehn and Yahr (HY) staging, the Unified Parkinson's Disease Rating Scale (UPDRS) and the Mini-Mental State Examination (MMSE) were administered on the same day.

Results

Anhedonia (SHAPS score ≥ 3) was diagnosed in 15% of the patients. The SHAPS score was found to be significantly correlated with the HY stage and the UPDRS (I, IV_B, IV_C, total), BDI-II, AS and STAI (State, Trait) scores. A multivariate analysis revealed that the BDI-II and STAI (Trait) scores significantly influenced the SHAPS scores. The SHAPS scores were found to be negatively correlated with the QOL.

Conclusions

These findings indicate that anhedonia is associated with depression and anxiety. In addition, recognizing anhedonia in patients with PD is important since it may have a negative effect on the QOL.     

Optimism measured pre-operatively is associated with reduced pain intensity and physical symptom reporting after coronary artery bypass graft surgery

Objective

Optimism is thought to be associated with long-term favourable outcomes for patients undergoing coronary artery bypass graft (CABG) surgery. Our objective was to examine the association between optimism and post-operative pain and physical symptoms in CABG patients.

Methods

We assessed optimism pre-operatively in 197 adults undergoing CABG surgery, and then followed them up 6–8 weeks after the procedure to measure affective pain, pain intensity, and physical symptom reporting directly pertaining to CABG surgery.

Results

Greater optimism measured pre-operatively was significantly associated with lower pain intensity (β = − 0.150, CI = − 0.196 to − 0.004, p = .042) and fewer physical symptoms following surgery (β = − 0.287, CI = − 0.537 to − 0.036, p = .025), but not with affective pain, after controlling for demographic, clinical and behavioural covariates, including negative affectivity.

Conclusions

Optimism is a modest, yet significant, predictor of pain intensity and physical symptom reporting after CABG surgery. Having positive expectations may promote better recovery.
