Rating chronic medical illness burden in geropsychiatric practice and research: application of the Cumulative Illness Rating Scale

Diurnal cortisol and functional outcomes in post-acute rehabilitation patients

BACKGROUND

Cortisol is a stress-related hormone with a robust circadian rhythm where levels typically peak in the morning hours and decline across the day. Although acute cortisol increases resulting from stressors are adaptive, chronic elevated cortisol levels are associated with poor functioning. Studies have shown age-related changes in cortisol levels. The present study investigated the relationship between salivary diurnal cortisol and functional outcomes among older adults undergoing inpatient post-acute rehabilitation.

METHODS

Thirty-two older adults (mean age 78 years; 84% men) in a Veterans Administration inpatient post-acute rehabilitation unit were studied. Functional outcomes were assessed with the motor component of the Functional Independence Measure (mFIM; where mFIM change = discharge - admission score). Saliva samples were collected on 1 day at wake time, 45 minutes later, 11:30 AM, 2 PM, 4:30 PM, and bedtime. We analyzed the relationship between cortisol measures and functional outcomes, demographics, and health measures.

RESULTS

The analyses consistently showed that greater functional improvement (mFIM change) from admission to discharge was associated with lower comorbidity scores and higher cortisol levels at 2 PM, 4:30 PM, and bedtime. A morning cortisol rise was also associated with greater mFIM change.

CONCLUSIONS

Measurement of cortisol in saliva may be a useful biological marker for identification of patients who are "at risk" of lower benefits from inpatient rehabilitation services and who may require additional assistance or intervention during their post-acute care stay.

Safety and efficacy of electroconvulsive therapy for the treatment of agitation and aggression in patients with dementia

OBJECTIVES

Noncognitive behavioral disturbances including agitation and aggression frequently accompany the cognitive symptoms of dementia accounting for much of dementia's morbidity, yet treatment options are currently limited. The authors examine the safety and efficacy of Electroconvulsive Therapy (ECT) for agitation and aggression in dementia patients.

DESIGN

Retrospective systematic chart review.

SETTING

McLean Hospital's geriatric neuropsychiatry unit.

PARTICIPANTS

Sixteen patients with a diagnosis of dementia treated with ECT for agitation/aggression during 2004-2007.

MEASUREMENTS

Clinical charts were rated on the Pittsburgh Agitation Scale as the primary outcome, the Clinical Global Impression scale and the Global Assessment of Functioning pre- and post-ECT.

RESULTS

16 patients of mean age 66.6 ± 8.3 years were studied. Their average overall and pre-ECT lengths of stay were 59.7 ± 39.7 days and 23 ± 15.7 days, respectively. Patients received a mean of 9 ECT treatments, mostly bilateral. Patients showed significant reductions in their total Pittsburgh Agitation Scale scores from baseline after ECT (from 11.0 ± 5.0 to 3.9 ± 4.3 [F = 30.33, df = 1, 15, p < 0.001]). Clinical Global Impression scale decreased significantly (from 6.0 ± 0.6 pre-ECT to 2.1 ± 1.6 post-ECT [F = 112.97, df = 1, 15, p < 0.001]). Global Assessment of Functioning change was not significant (from 23.0 ± 4.9 to 26.9 ± 6.9 [F = 5.73, df = 1, 13, p = 0.32]). Only one patient, in whom ECT was discontinued following 11 bilateral treatments, showed no improvement. Eight patients showed transient postictal confusion, which typically resolved within 48 hours. Two patients showed more severe postictal confusion that required modification of treatment.

CONCLUSIONS

These results suggest that ECT is an effective and safe treatment for agitation and aggression in dementia. Further prospective studies are warranted.

A randomized phase II trial of first-line treatment with gemcitabine, erlotinib, or gemcitabine and erlotinib in elderly patients (age ≥70 years) with stage IIIB/IV non-small cell lung cancer

INTRODUCTION

Single-agent gemcitabine is a standard of care for elderly patients with advanced non-small cell lung cancer, but novel therapies are needed for this patient population.

METHODS

We performed a noncomparative randomized phase II trial of gemcitabine, erlotinib, or the combination in elderly patients (age ≥70 years) with stage IIIB or IV non-small cell lung cancer. Patients were randomized to arms: A (gemcitabine 1200 mg/m on days 1 and 8 every 21 days), B (erlotinib 150 mg daily), or C (gemcitabine 1000 mg/m on days 1 and 8 every 21 days and erlotinib 100 mg daily). Arms B and C were considered investigational; the primary objective was 6-month progression-free survival.

RESULTS

Between March 2006 and May 2010, 146 eligible patients received protocol therapy. The majority of the patients (82%) had stage IV disease, 64% reported adenocarcinoma histology, 90% reported current or previous tobacco use, and 28% had a performance status of 2. The 6-month progression-free survival rate observed in arms A, B, and C was 22% (95% confidence interval [CI] 11-35), 24% (95% CI 13-36), and 25% (95% CI 15-38), respectively; the median overall survival observed was 6.8 months (95% CI 4.8-8.5), 5.8 months (95% CI 3.0-8.3), and 5.6 months (95% CI 3.5-8.4), respectively. The rate of grade ≥3 hematological and nonhematological toxicity observed was similar in all three arms. The best overall health-related quality of life response did not differ between treatment arms.

CONCLUSIONS

Erlotinib or erlotinib and gemcitabine do not warrant further investigation in an unselected elderly patient population.

The electronic Cumulative Illness Rating Scale: a reliable and valid tool to assess multi-morbidity in primary care

RATIONALE, AIMS AND OBJECTIVES

The presence of multiple concomitant diseases is an increasing health problem, and prompted by the limitations of the disease count, several indices measuring multi-morbidity or co-morbidity have been described to account for the overall burden of morbidity. The Cumulative Illness Rating Scale (CIRS) is one of those indices. We developed an electronic version of the CIRS (eCIRS) to take advantage of computerized data processing. The aim of this study was to evaluate the reliability and validity of the eCIRS scored in a primary care setting.

METHODS

Two nurses interviewed 48 adult patients recruited during consecutive consultation periods in a primary care setting and scored the eCIRS in a random order during two sessions of data collection (T1 and T2) 1 month apart. We measured intra- and inter-rater reliability [intra-class correlation coefficient (ICC)]. We also assessed concomitant validity [(Pearson's correlation (r)] using standard CIRS scored by the attending family doctors.

RESULTS

Intra-rater (ICC: 0.90 and 0.95) and inter-rater reliability (ICC: 0.86 and 0.91) were both excellent. No significant differences between the nurses' scores at T1 and T2 (P = 0.40 for nurse 1, P = 0.73 for nurse 2) were found. The eCIRSs scored by the nurses were highly correlated with the CIRSs scored by the doctors (r = 0.80 and 0.88).

CONCLUSION

Reliable and valid, the eCIRS completed during patient interviews with trained nurses can be used to quantify multi-morbidity in primary care, either for research or clinical use.

Poor self-reported sleep quality predicts mortality within one year of inpatient post-acute rehabilitation among older adults

STUDY OBJECTIVE

To evaluate the association between self-reported sleep quality among older adults during inpatient post-acute rehabilitation and one-year survival.

DESIGN

Prospective, observational cohort study.

SETTING

Two inpatient post-acute rehabilitation sites (one community and one Veterans Administration).

PARTICIPANTS

Older patients (aged ≥ 65 years, n = 245) admitted for inpatient post-acute rehabilitation.

INTERVENTIONS

None.

MEASUREMENTS AND RESULTS

Within one year of post-acute rehabilitation, 57 participants (23%) were deceased. Cox proportional hazards models showed that worse Pittsburgh Sleep Quality Index (PSQI) total scores during the post-acute care stay were associated with increased mortality risk when controlling for amount of rehabilitation therapy received, comorbidities, and cognitive functioning (Hazard ratio [95% CI] = 1.11 [1.02-1.20]). Actigraphically estimated sleep was unrelated to mortality risk.

CONCLUSIONS

Poorer self-reported sleep quality, but not objectively estimated sleep parameters, during post-acute rehabilitation was associated with shorter survival among older adults. This suggests self-reported poor sleep may be an important and potentially modifiable risk factor for negative outcomes in these vulnerable older adults. Studies of interventions to improve sleep quality during inpatient rehabilitation should therefore be undertaken, and the long-term health benefits of improved sleep should be explored.

Time to discontinuation among the three second-generation antidepressants in a naturalistic outpatient setting of depression

AIM

This study compared the discontinuation time among the three second-generation antidepressants (paroxetine, venlafaxine, and mirtazapine) in a naturalistic setting for outpatient treatment of depression.

METHODS

This study used data from retrospectively reviewed medical records of patients admitted to an outpatient psychiatric clinic between January 2003 and December 2005. Patient groups (paroxetine-, venlafaxine-, and mirtazapine-treated) were compared with each other with regard to their discontinuation times for a 6-month period after treatment initiation. The data were analyzed, using a Kaplan-Meier survival analysis, and a Cox proportional hazards regression model.

RESULTS

There were no significant differences in discontinuation times among the three second-generation antidepressants during the 6-month period after initiation of drug therapy.

CONCLUSIONS

In a naturalistic setting for the care of depression, it seems that there are no differences in discontinuation times among these three second-generation antidepressants.

Clinical features of depression in outpatients with and without co-occurring general medical conditions in STAR*D: confirmatory analysis

BACKGROUND

Concurrent medical comorbidity influences the accurate diagnosis and treatment of major depressive disorder (MDD).

OBJECTIVE

The objective of this study was to validate previous findings from the Sequenced Treatment Alternatives to Relieve Depression (STAR*D) study using a confirmation analysis in a previously unanalyzed cohort.

DESIGN

Baseline cross-sectional case-control study of patients enrolling in a prospective randomized multistage treatment study of nonpsychotic MDD.

SETTING

Fourteen regional U.S. centers representing 18 primary care and 23 psychiatric practices.

PARTICIPANTS

2541 outpatients with DSM-IV nonpsychotic MDD.

MEASUREMENTS

Sociodemographic status, medical illness ratings, psychiatric status, quality of life, and DSM-IV depression symptom ratings.

RESULTS

The prevalence of significant general medical comorbidity in this population was 50.0% (95% CI = 48.1% to 52.0%), consistent with findings reported for the first cohort. Concurrent significant medical comorbidity was associated with older age, lower income, unemployment, limited education, and longer duration of index depressive episode. The group with significant medical comorbidity reported higher rates of somatic symptoms, gastrointestinal symptoms, sympathetic arousal, and leaden paralysis. These results were generally consistent between the 2 cohorts from STAR*D.

CONCLUSIONS

Major depressive disorder with concurrent general medical conditions is associated with a specific sociodemographic profile and pattern of depressive symptoms. This association has implications for diagnosis and clinical care.

Predicting the risk of chemotherapy toxicity in older patients: the Chemotherapy Risk Assessment Scale for High-Age Patients (CRASH) score

BACKGROUND

Tools are lacking to assess the individual risk of severe toxicity from chemotherapy. Such tools would be especially useful for older patients, who vary considerably in terms of health status and functional reserve.

METHODS

The authors conducted a prospective, multicentric study of patients aged ≥70 years who were starting chemotherapy. Grade 4 hematologic (H) or grade 3/4 nonhematologic (NH) toxicity according to version 3.0 of the Common Terminology Criteria for Adverse Events was defined as severe. Twenty-four parameters were assessed. Toxicity of the regimen (Chemotox) was adjusted using an index to estimate the average per-patient risk of chemotherapy toxicity (the MAX2 index). In total, 562 patients were accrued, and 518 patients were evaluable and were split randomly (2:1 ratio) into a derivation cohort and a validation cohort.

RESULTS

Severe toxicity was observed in 64% of patients. The Chemotherapy Risk Assessment Scale for High-Age Patients (CRASH) score was constructed along 2 subscores: H toxicity and NH toxicity. Predictors of H toxicity were lymphocytes, aspartate aminotransferase level, Instrumental Activities of Daily Living score, lactate dehydrogenase level, diastolic blood pressure, and Chemotox. The best model included the 4 latter predictors (risk categories: low, 7%; medium-low, 23%; medium-high, 54%; and high, 100%, respectively; P(trend) < .001). Predictors of NH toxicity were hemoglobin, creatinine clearance, albumin, self-rated health, Eastern Cooperative Oncology Group performance, Mini-Mental Status score, Mini-Nutritional Assessment score, and Chemotox. The 4 latter predictors provided the best model (risk categories: 33%, 46%, 67%, and 93%, respectively; P(trend) < .001). The combined risk categories were 50%, 58%, 77%, and 79%, respectively; P(trend) < .001). Bootstrap internal validation and independent sample validation demonstrated stable risk categorization and P(trend) < .001.

CONCLUSIONS

The CRASH score distinguished several risk levels of severe toxicity. The split score discriminated better than the combined score. To the authors' knowledge, this is the first score systematically integrating both chemotherapy and patient risk for older patients and has a potential for future clinical application.

A critique of the evidence base for non-pharmacological sleep interventions for persons with dementia

Disordered sleep in persons with dementia is a contributing factor for a range of health problems. The evidence base for non-pharmacological interventions has not been evaluated and clearly presented in the literature. This paper provides a structured Critical Literature Review of the evidence for non-pharmacological interventions to reduce disordered sleep in persons with dementia. The systematic search retrieved 29 studies that were evaluated for methodological quality. The quality of evidence ranged from conclusive for light therapy and activity to inconclusive for most other interventions. There is a paucity of conclusive research for non-pharmacological sleep interventions for persons with dementia. Most of the evidence about effective interventions is anecdotal and untested. There is a need for rigorous scientific inquiry, coupled with tacit knowledge to build a strong evidence base on non-pharmacological interventions for disordered sleep for persons with dementia.

Prospective cohort study of suicide attempters aged 70 and above: one-year outcomes

BACKGROUND

Most elderly persons who attempt suicide suffer from depression. This study aimed to investigate one-year outcomes in suicide attempters aged 70+, and to identify predictors of these outcomes.

METHODS

101 persons (mean age 80) who were hospitalized after a suicide attempt were interviewed at baseline and followed for one year by record linkage. Face-to-face interviews were carried out with 71% of those who were alive after one year (60 out of 85). Outcome measures included major/minor depression, Montgomery-Asberg Depression Rating Scale (MADRS) score, repeat non-fatal/fatal suicidal behavior and all-cause mortality.

RESULTS

One half (52%) of all those who were interviewed scored <10 on the MADRS at follow-up. Among those with major depression at baseline, two thirds (26 out of 39) no longer fulfilled criteria for this disorder. Factors associated with non-remission of major depression (MADRS ≥ 10) included higher baseline depression and anxiety scores, higher suicide intent and lower Sense of Coherence. There were two suicides and six non-fatal repeat attempts. The relative risk of death (any cause) was 2.53 (95% CI = 1.45-4.10, p<0.001).

LIMITATIONS

This is a naturalistic study; participants received non-uniform treatment as usual. The proportion with repeat suicidal behavior was lower than anticipated and the study was thus underpowered with regard to this outcome.

CONCLUSIONS

Half of the surviving attempters were free from depressive symptoms at one-year follow-up and there were relatively few repeat attempts. However, all cause mortality remained high in this elderly cohort.

Relationship of orthostatic blood pressure to white matter hyperintensities and subcortical volumes in late-life depression

BACKGROUND

Structural brain abnormalities are associated with late-life major depression, with numerous studies reporting increased white matter hyperintensities (WMH) and reduced cortical/subcortical grey matter volumes. There is strong evidence linking vascular disease to WMH, but limited evidence on its association with subcortical volumes.

AIMS

To investigate the relationship of orthostatic blood pressure changes to WMH and subcortical grey matter volumes in late-life depression.

METHOD

Thirty-eight people with depression and a similarly aged comparison group (n = 30) underwent fluid attenuated inversion recovery (FLAIR) and T(1)-weighted magnetic resonance imaging as well as systematic orthostatic blood pressure assessments. Volumetric estimates of WMH and subcortical grey matter were obtained for each participant and the relationship to blood pressure drop on active stand was examined.

RESULTS

An association between orthostatic systolic blood pressure drop and WMH volumes in temporal and parietal regions was found in the depression group (age-corrected partial correlation r' = 0.31-0.35, P<0.05). Subcortical volumes were not related to blood pressure changes or WMH volumes in either group.

CONCLUSIONS

We found evidence for an association between the degree of orthostatic systolic blood pressure drop and WMH volume in the depression group. Since blood pressure drops lead to WMH in animals our findings suggest systolic blood pressure drops may be a factor contributing to these lesions in late-life depression.

Depression symptom ratings in geriatric patients with bipolar mania

OBJECTIVE

Given the paucity of information available regarding standardized ratings of depression symptoms in bipolar manic states, and in particular those in older adults, we explored depression ratings in symptomatic participants in a multicenter study of treatment of bipolar I disorder in late life.

METHODS

Baseline data was obtained from the first 100 patients enrolled in an NIMH-funded, 9-week, randomized, double-blind RCT comparing treatment with lithium or valproate in patients of age 60 years and older with Type I Bipolar mania or hypomania. This multi-site study was conducted at six academic medical centers in the United States and enrolled inpatients and outpatients with a total Young Mania Rating Scale (YMRS) score of 18 or greater. Depressive symptoms were evaluated with the Hamilton Depression Rating Scale (HAM-D) and the Montgomery-Asberg Depression Rating Scale (MADRS). The criterion for at least moderate bipolar depressive symptoms was the European College of Neuropsychopharmacology (ECNP) Consensus Meeting definition of HAM-D 17 total score >20.

RESULTS

Eleven percent of patients had mixed symptoms defined by depression scale severity according to ECNP criterion. In the overall sample, total scores on the two depression scales were highly correlated. Total YMRS scores of this mixed symptom group were similar to the remainder of the sample.

CONCLUSIONS

These preliminary findings suggest that moderate to severe depressive symptoms occur in about one in ten bipolar manic elders. Future studies are needed to further evaluate symptom profiles, clinical correlates, and treatments for bipolar older adults with combined manic and depressive symptoms.

Standards for epidemiologic studies and surveillance of epilepsy

Worldwide, about 65 million people are estimated to have epilepsy. Epidemiologic studies are necessary to define the full public health burden of epilepsy; to set public health and health care priorities; to provide information needed for prevention, early detection, and treatment; to identify education and service needs; and to promote effective health care and support programs for people with epilepsy. However, different definitions and epidemiologic methods complicate the tasks of these studies and their interpretations and comparisons. The purpose of this document is to promote consistency in definitions and methods in an effort to enhance future population-based epidemiologic studies, facilitate comparison between populations, and encourage the collection of data useful for the promotion of public health. We discuss: (1) conceptual and operational definitions of epilepsy, (2) data resources and recommended data elements, and (3) methods and analyses appropriate for epidemiologic studies or the surveillance of epilepsy. Variations in these are considered, taking into account differing resource availability and needs among countries and differing purposes among studies.

[Comparison of three methods for measuring multiple morbidity according to the use of health resources in primary healthcare]

OBJECTIVE

To compare three methods of measuring multiple morbidity according to the use of health resources (cost of care) in primary healthcare (PHC).

DESIGN

Retrospective study using computerized medical records.

SETTING

Thirteen PHC teams in Catalonia (Spain).

PARTICIPANTS

Assigned patients requiring care in 2008.

MAIN MEASUREMENTS

The socio-demographic variables were co-morbidity and costs. Methods of comparison were: a) Combined Comorbidity Index (CCI): an index itself was developed from the scores of acute and chronic episodes, b) Charlson Index (ChI), and c) Adjusted Clinical Groups case-mix: resource use bands (RUB). The cost model was constructed by differentiating between fixed (operational) and variable costs.

STATISTICAL ANALYSIS

3 multiple lineal regression models were developed to assess the explanatory power of each measurement of co-morbidity which were compared from the determination coefficient (R(2)), p< .05.

RESULTS

The study included 227,235 patients. The mean unit of cost was €654.2. The CCI explained an R(2)=50.4%, the ChI an R(2)=29.2% and BUR an R(2)=39.7% of the variability of the cost. The behaviour of the ICC is acceptable, albeit with low scores (1 to 3 points), showing inconclusive results.

CONCLUSIONS

The CCI may be a simple method of predicting PHC costs in routine clinical practice. If confirmed, these results will allow improvements in the comparison of the case-mix.

Complementary use of tai chi chih augments escitalopram treatment of geriatric depression: a randomized controlled trial

BACKGROUND

Nearly two-thirds of elderly patients treated for depression fail to achieve symptomatic remission and functional recovery with first-line pharmacotherapy. In this study, we ask whether a mind-body exercise, Tai Chi Chih (TCC), added to escitalopram will augment the treatment of geriatric depression designed to achieve symptomatic remission and improvements in health functioning and cognitive performance.

METHODS

: One hundred twelve older adults with major depression age 60 years and older were recruited and treated with escitalopram for approximately 4 weeks. Seventy-three partial responders to escitalopram continued to receive escitalopram daily and were randomly assigned to 10 weeks of adjunct use of either 1) TCC for 2 hours per week or 2) health education (HE) for 2 hours per week. All participants underwent evaluations of depression, anxiety, resilience, health-related quality of life, cognition, and inflammation at baseline and during 14-week follow-up.

RESULTS

Subjects in the escitalopram and TCC condition were more likely to show greater reduction of depressive symptoms and to achieve a depression remission as compared with those receiving escitalopram and HE. Subjects in the escitalopram and TCC condition also showed significantly greater improvements in 36-Item Short Form Health Survey physical functioning and cognitive tests and a decline in the inflammatory marker, C-reactive protein, compared with the control group.

CONCLUSION

: Complementary use of a mind-body exercise, such as TCC, may provide additional improvements of clinical outcomes in the pharmacologic treatment of geriatric depression.

Very mild dementia and medical comorbidity independently predict health care use in the elderly

OBJECTIVE

To determine whether dementia status and medical burden were independent predictors of emergency department (ED) visits and hospitalizations in older patients from an urban geriatric practice participating in a primary care based cognitive screening program.

PARTICIPANTS AND METHODS

A comprehensive chart review was conducted for 300 African American and Caucasian patients, including 46 with prevalent dementia and 28 with incident dementia using the Cumulative Illness Burden Scale. Hospital-based claims data was used to retrieve ED visits and hospital admissions for 5 years following baseline assessment.

RESULTS

Patients with dementia had a 49% higher rate of ED visits (IRR = 1.49; 95% CI = 1.06, 2.09) and an 83% higher risk of death than patients without dementia (HR = 1.83; 95% CI = 3.07, 0.03). Dementia status predicted hospital admissions after adjustment for medical burden (IRR = 1.37; 95% CI = 0.99, 1.89). For each one point increase in medical burden, there was an 11% increase in ED visits (IRR = 1.11; 95% CI = 1.06, 1.16), a 13% increase in hospital admissions (IRR = 1.13; 95% CI = 1.09, 1.17), and an 11% higher risk of death (HR = 1.11; 95% CI = 1.04, 1.17). Age did not predict utilization.

CONCLUSION

Dementia status and medical burden were independent predictors of ED visits and death in patients with clinically diagnosed dementia followed from the early stage of disease.

Changes in neuropsychological functioning following treatment for late-life generalised anxiety disorder

BACKGROUND

Generalised anxiety disorder (GAD) in older adults is associated with neuropsychological impairment. Aims We examined neuropsychological functioning in older adults with GAD in comparison with psychiatrically healthy older adults at baseline, and we examined changes following a 12-week placebo-controlled trial of escitalopram.

METHOD

A total of 160 participants without dementia aged ≥60 with current GAD and 37 individuals in a comparison group without psychiatric history underwent neuropsychological assessment. Of these, 129 participants with GAD were reassessed post-treatment (trial registration: NCT00105586).

RESULTS

The participants with GAD performed worse than the comparison group in information processing speed, working memory, inhibition, problem-solving (including concept formation and mental flexibility) and immediate and delayed memory. Neuropsychological functioning was correlated with everyday functioning. After treatment, those with low cognitive scores experienced working memory, delayed memory and visuospatial ability improvement and those who reported clinical improvement in anxiety exhibited improvement in the ability to engage inhibition and episodic recall. These improvements were modest and of similar magnitude in both treatment conditions.

CONCLUSIONS

Generalised anxiety disorder in older adults is associated with neuropsychological impairments, which are associated with functional impairment. Those with GAD who either have a low cognitive performance or report clinical improvement in anxiety post-treatment, show improvement in multiple cognitive domains. These findings underscore the importance of treatments that aid cognition as well as anxiety symptoms.

Cortical thickness and VBM-DARTEL in late-life depression

BACKGROUND

Numerous studies have revealed structural brain changes in late life depression, mainly in white matter or whole lobes with few focussing just on grey matter (GM). The objective was to investigate GM changes in older depressed and similar aged healthy subjects using two different methods, cortical thickness in frontal lobe structures and voxel-based morphometry (VBM).

METHODS

Sixty eight subjects participated (30 healthy comparison subjects, 38 depressed) and underwent 3T T1 MR imaging as well as clinical and cognitive assessments. Frontal cortical thickness was measured using FreeSurfer while VBM was undertaken using the DARTEL algorithm in SPM8. Group differences in cortical thickness and GM volumes were assessed using ANCOVA. Effects of cortical thickness and VBM results on cognitive and depression variables were also investigated.

RESULTS

No significant differences in frontal lobe cortical thickness were observed between groups (F(1, 62) ≤ 2.7, p ≥ 0.1). In addition, no significant relationships of cortical thickness on cognitive and depression scores were identified (partial correlation |r'|=0.01-0.31, p ≥ 0.06). VBM showed that GM volumes were indistinguishable between groups but significant age effects were apparent, independent of diagnosis.

CONCLUSIONS

Results suggest that cortical GM changes in late life depression (LLD) are similar to healthy older subjects and appear to be related to age rather than cognitive or depressive symptoms. Changes to white matter and subcortical GM structures may be more relevant in explaining the underlying neurobiology of LLD.

Sense of coherence in elderly suicide attempters: the impact of social and health-related factors

BACKGROUND

An association between sense of coherence (SOC) and suicidal behavior has been suggested. The aim of this study was to identify factors associated with low SOC in elderly suicide attempters.

METHODS

Eighty non-demented hospital-treated suicide attempters aged 70 years and older (38 men, 42 women, mean age 79.4 years) took part in an interview with a research psychologist and completed the 29-item SOC questionnaire. The interview included questions regarding social situation and health-related factors. The Comprehensive Psychopathological Rating Scale (CPRS) provided symptom ratings that were used in a diagnostic algorithm for DSM-IV major depression. The Cumulative Illness Rating Scale for Geriatrics (CIRS-G) was used to identify individuals with serious physical illness.

RESULTS

There was a strong relationship between major depression and SOC. While we could show no relationship between severe physical illness and SOC, associations were demonstrated with social variables including too little time spent with children, too little time spent with grandchildren and having moved within the past five years. These associations remained significant in regression models adjusted for sex, age and major depression.

CONCLUSIONS

A number of social variables were independently related to SOC in elderly suicide attempters. Prospective studies are needed in order to determine whether SOC-strengthening interventions can reduce the risk of suicidal behavior in seniors.

Augmenting antidepressant medication with modular CBT for geriatric generalized anxiety disorder: a pilot study

OBJECTIVE

Generalized anxiety disorder (GAD) is a prevalent psychiatric condition in older adults with deleterious effects on health and cognition. Although selective serotonin reuptake inhibitor (SSRI) medications have some efficacy as acute treatments for geriatric GAD, incomplete response is the most common outcome of monotherapy. We therefore developed a novel sequential treatment strategy, using personalized, modular cognitive-behavioral therapy (mCBT) to augment SSRI medication.

METHOD

In an open label pilot study (N = 10), subjects received a sequenced trial of 12 weeks of escitalopram followed by 16 weeks of escitalopram augmented with mCBT. We also examined the maintenance effects of mCBT over a 28-week follow-up period following drug discontinuation and termination of psychotherapy.

RESULTS

Results suggest that (1) adding mCBT to escitalopram significantly reduced anxiety symptoms and pathological worry, resulting in full remission for most patients and (2) some patients maintained response after all treatments were withdrawn.

CONCLUSION

Findings suggest that mCBT may be an effective augmentation strategy when added to SSRI medication and provide limited support for the long-term benefit of mCBT after discontinuation of pharmacotherapy.

Influence of chronic diseases on long-term change in physical health: a consultation-survey linkage cohort study in general practice

PURPOSE

To investigate the influence of disease severity within cardiovascular disease (CVD) and musculoskeletal (MSK) disorder spectrums on physical health change over 3 years.

METHODS

Consultation records of 4,672 patients aged 50 years and above from six general practices were linked to their baseline and 3-year Short-Form-12 (SF-12) physical component summary (PCS) scores. Associations between exclusive diagnostic categories and comorbid counts with physical health change over 3 years were examined.

RESULTS

There were 1,371 (29.3%) CVD and 1,972 (42.2%) MSK consulters. Adjusted additional change in PCS scores relative to hypertension ranged from -0.43 (95% confidence interval -2.5, 1.7) for atrial fibrillation to -2.09 (-4.2, 0.0) for heart failure. In the MSK spectrum, changes relative to soft tissue disorder ranged from -0.63 (-3.0, 1.8) for soft tissue pain to -1.09 (-4.1, 2.0) for inflammatory polyarthropathy. A trend in association between increasing disease severity and deterioration in physical health was only observed within the CVD spectrum, and this trend was retained in those with CVD and higher levels of comorbidity.

CONCLUSIONS

CVD severity with higher levels of comorbidity was associated with greater relative deterioration in long-term physical health. Such findings were not found for the MSK cohorts, suggesting the differing health impact of different chronic diseases.

Hyperglycemia during chemotherapy for hematologic and solid tumors is correlated with increased toxicity

BACKGROUND

Few data are available concerning how glycemic control can affect outcomes in cancer patients treated with chemotherapy.

METHODS

Charts of non-Hodgkin lymphoma (NHL) and prostate cancer (PC) patients treated at Moffitt Cancer Center between January 1999 and September 2006 were reviewed, and patients who received cyclophosphamide, doxoruicin, vincristine, prednisone, rituximab or Docetaxel plus steroids were eligible. Demographics, vitals, comorbidity, laboratory parameters including baseline and average glucose level during chemotherapy, G4 hematological toxicity (HemT), and G3-G4 non-hematological toxicity (NHemT), progression, and death dates were recorded.

RESULTS

A total of 349 patients were eligible (NHL/PC: 162/187). G4 HemT was experienced by 76 (47%) NHL and 9 (5%) PC patients. Seventy-nine NHL and 90 PC patients had G3-G4 NHemT. The most frequent NHemT were as follows: neuropathy (25.3%), fever (non-neutropenic, 18.9%), fatigue (15.2%), for NHL; and fatigue (22.1%), thromboembolic events (11.6%), and diarrhea (9.3%) for PC. For NHL patients, G3-G4 NHemT was associated with baseline hyperglycemia (P = 0.0384, Wilcoxon Rank-Sum test) as well as with average glycemia during chemotherapy (P = 0.0048), whereas there was no significant correlation for HemT. For PC patients, a positive correlation was found between baseline hyperglycemia and G4 HemT (P = 0.0241), while univariate correlations between average glycemia during chemotherapy and G4 HemT and between both baseline and average glycemia with NHemT were not significant, multivariate correlation between average glycemia during chemotherapy and overall severe toxicity was significant at 0.05 level.

CONCLUSIONS

In NHL patients, hyperglycemia correlates with NHemT, and a similar although less clear pattern is suggested in PC patients. Prospective studies are needed to assess whether a better glycemic control during chemotherapy can improve toxicity and outcomes.

Lethal forethought: delayed reward discounting differentiates high- and low-lethality suicide attempts in old age

BACKGROUND

The decision to commit suicide may be impulsive, but lethal suicidal acts often involve planning and forethought. People who attempt suicide make disadvantageous decisions in other contexts, but nothing is known about the way they decide about the future. Can the willingness to postpone future gratification differentiate between individuals prone to serious, premeditated and less serious, unplanned suicidal acts?

METHODS

Four groups of depressed participants aged 60 and older made choices between smaller immediate and larger delayed monetary rewards: 15 who had made high-lethality suicide attempts, 14 who had made low-lethality suicide attempts, 12 who seriously contemplated suicide, and 42 people with depression, but no history of suicidal thoughts. The reference group was 31 psychiatrically healthy elders.

RESULTS

Individuals who had made low-lethality attempts displayed an exaggerated preference for immediate rewards compared with nonsuicidal depressed and healthy control subjects. Those who had carried out high-lethality suicide attempts were more willing to delay future rewards, compared with low-lethality attempters. Better planned suicide attempts were also associated with willingness to wait for larger rewards. These effects were unchanged after accounting for education, global cognitive function, substance use disorders, psychotropic medications, and possible brain injury from attempts. Discount rates were correlated with having debt, but were not significantly associated with income, hopelessness, depressive severity, premorbid IQ, age at first attempt, or choice of violent means.

CONCLUSIONS

Although clinicians often focus on impulsivity in patients at risk for suicide, these data suggest that identifying biological characteristics and treatments for nonimpulsive suicidal older people may be even more important.

Intelligent Systems For Assessing Aging Changes: home-based, unobtrusive, and continuous assessment of aging

OBJECTIVES

To describe a longitudinal community cohort study, Intelligent Systems for Assessing Aging Changes, that has deployed an unobtrusive home-based assessment platform in many seniors homes in the existing community.

METHODS

Several types of sensors have been installed in the homes of 265 elderly persons for an average of 33 months. Metrics assessed by the sensors include total daily activity, time out of home, and walking speed. Participants were given a computer as well as training, and computer usage was monitored. Participants are assessed annually with health and function questionnaires, physical examinations, and neuropsychological testing.

RESULTS

Mean age was 83.3 years, mean years of education was 15.5, and 73% of cohort were women. During a 4-week snapshot, participants left their home twice a day on average for a total of 208 min per day. Mean in-home walking speed was 61.0 cm/s. Participants spent 43% of days on the computer averaging 76 min per day.

DISCUSSION

These results demonstrate for the first time the feasibility of engaging seniors in a large-scale deployment of in-home activity assessment technology and the successful collection of these activity metrics. We plan to use this platform to determine if continuous unobtrusive monitoring may detect incident cognitive decline.

Impact of prior pharmacotherapy on remission of psychotic depression in a randomized controlled trial

Having failed to respond to an adequate antidepressant treatment course predicts poorer treatment outcomes in patients with major depression. However, little is known about the impact of prior treatment on the outcome of major depression with psychotic features (MDpsy). We examined the effect of prior treatment history on the outcome of pharmacotherapy of MDpsy in patients who participated in the STOPD-PD study, a randomized, double-blind, clinical trial comparing a combination of olanzapine plus sertraline vs. olanzapine plus placebo. The strength of treatment courses received prior to randomization was classified using a validated method. A hierarchy of outcomes was hypothesized based on treatments received prior to randomization and randomized treatment. A high remission rate was observed in subjects with a history of no prior treatment or inadequate treatment who were treated with a combination of olanzapine and sertraline. A low remission rate was observed in subjects who had previously failed to respond to an antidepressant alone and who were treated with olanzapine monotherapy. A low remission rate was also observed in subjects who had previously failed to respond to a combination of an antipsychotic and an antidepressant. Similar to patients with major depression, these results emphasize the impact of prior pharmacotherapy on treatment outcomes in patients with MDpsy.

A study of orthostatic hypotension, heart rate variability and baroreflex sensitivity in late-life depression

BACKGROUND

To determine if subjects with late-life depression have significant cardiovascular autonomic abnormalities (orthostatic blood pressure drop, heart rate variability and baroreflex sensitivity).

METHODS

A case-control study, in secondary care facilities, of forty two older (> 60 years) individuals with lifetime history of major depression and 31 age and sex matched comparison subjects. Autonomic function was assessed by measuring postural blood pressure, heart rate variability and baroreflex sensitivity using non-invasive beat-to-beat blood pressure and continuous ECG monitoring (Task Force® Monitor, CNSystems, Graz, Austria). The main outcome measures were maximal reduction in systolic blood pressure with active stand, low frequency and high frequency heart rate variability and baroreflex sensitivity using the sequence method.

RESULTS

Participants with depression had a significantly larger drop in systolic blood pressure on standing from a supine position. Depression was an independent predictor for developing systolic orthostatic hypotension. Depressed participants also had lower low frequency heart rate variability and lower baroreflex sensitivity.

LIMITATIONS

This was a cross-sectional and observational study; longitudinal effects or causality cannot be inferred from the findings and we could not distinguish state from trait related changes.

CONCLUSIONS

Late-life depression has been associated with vascular disease but previous studies examining vascular risk factors have been inconsistent. Brain MRI white matter hyperintensities are ischemic and increased in late-life depression and associated with orthostatic blood pressure drops in animals. The presence of autonomic abnormalities in late-life depression may partly explain these inconsistencies and be associated with the development of brain white matter hyperintensities.

Impairment in risk-sensitive decision-making in older suicide attempters with depression

Suicidal behavior is a potentially lethal complication of late-life depression. In younger adults, suicide has been linked to abnormal decision-making ability. Given that there are substantial age-related decreases in decision-making ability, and that older adults experience environmental stressors that require effective decision-making, we reasoned that impaired decision-making may be particularly relevant to suicidal behavior in the elderly. We thus compared performance on a probabilistic decision-making task that does not involve working memory ("Cambridge Gamble Task") in four groups of older adults: (1) individuals with major depression and a history of suicide attempt (n = 25), (2) individuals with major depression with active suicidal ideation but no suicide attempt (n = 13), (3) individuals with major depression without suicidality (n = 35), and (4) nondepressed control subjects (n = 22). There was a significant effect of group on quality of decision-making, whereby the suicide attempters exhibited poorer ability to choose the likely outcome, compared with the nonsuicidal depressed and nondepressed comparison subjects. There were no group differences in betting behavior. The suicide attempters differed in several aspects of social problem-solving on a self-report scale. Quality of decision-making was negatively correlated with the score on the impulsive/careless problem-solving subscale. These data suggest that older suicide attempters have a deficit in risk-sensitive decision-making, extending observations in younger adults. More specifically, older suicide attempters seem to neglect outcome probability and make poor choices. These impairments may precipitate and perpetuate suicidal crisis in depressed elders. Identification of decision-making impairment in suicidal elders may help with designing effective interventions.

Neuropsychological profiles and short-term outcome in late-onset depression

OBJECTIVE

Neuropsychological impairments are common in older persons with late-onset depression. This study examined the relationship between neuropsychological profiles and short-term outcome in late-onset depression.

METHODS

A total of 54 non-demented Chinese elders presented with their first major depressive episode after 60 years of age participated in this study and were treated according to a standardised protocol. At entry, they were assessed on neurological signs (Parkinsonian features and neurological soft signs) and neuropsychological measures (executive function, psychomotor-speed, attention and working memory, episodic memory, conceptualisation, construction and global cognitive function). The Hamilton Depression Rating Scale (HAM-D) was administered at baseline, the sixth and 12th week of treatment.

RESULTS

Abnormal fist-edge-palm (FEP) test, a sign reflecting impairment in motor sequencing, was more common in non-remitters (defined as HAM-D score above 7) at the 12th week of treatment.

CONCLUSIONS

The FEP test may be included in the clinical assessment for patients with late-onset depression to identify a susceptible group who may require more intensive treatment. Further research is warranted to ascertain the link between late-onset depression, neuropsychological deficits and prognosis.

Multisite, open-label, prospective trial of lamotrigine for geriatric bipolar depression: a preliminary report

AIMS

This is a multisite, 12-week, open-label trial of lamotrigine augmentation in 57 older adults (≥ 60 years; mean ± SD age = 66.5 ± 6.7 years) with either type I or type II bipolar depression.

METHODS

Primary outcome measure was change from baseline on the Montgomery-Åsberg Depression Rating Scale (MADRS). Secondary outcome measures included Hamilton Depression Rating Scale (HAM-D), Clinical Global Impression-Bipolar version (CGI-BP), and the WHO-Disability Assessment Schedule II (WHO-DAS II). The Udvalg for Kliniske Undersøgelser (UKU) was used to assess side effects.

RESULTS

A total of 77.2% of the study subjects had bipolar I disorder. The mean (SD) lamotrigine dose was 150.9 (68.5) mg/day. There was significant improvement in the MADRS, HAM-D, CGI-BP, and in most domains on the WHO-DAS II. For patients for whom final MADRS score was available: 31 (57.4%) met remission criteria and 35 (64.8%) met response criteria. There were 19/57 (33.3%) who dropped out of the study prematurely, with 6 dropouts due to adverse events (4 cases of rash, 1 manic switch, and 1 hyponatremia). Two cases of rash were possibly drug related and were resolved with drug discontinuation. The most common UKU adverse effects were reduced sleep duration (n = 14, 24.6%), weight loss (n = 12, 21.1%), increased dream activity (n = 12, 21.1%), polyuria/polydipsia (n = 11, 19.3%), weight gain (n = 9, 15.8%), diminished sexual desire (n = 9, 15.8%), increased sleep (n = 9, 15.8%), lassitude/fatigue (n = 8, 14%), and unsteady gait (n = 8, 14%). No significant changes in electrocardiogram or laboratory tests were observed.

CONCLUSIONS

In bipolar depressed elders, lamotrigine was associated with improvement in depression, psychopathology, and functional status. There was a moderate number of adverse events, although relationship of adverse events (particularly falls) to study medication could not be clearly determined in this uncontrolled trial. Controlled studies are needed to further evaluate efficacy and tolerability of lamotrigine therapy in geriatric bipolar depression.

Results of comprehensive geriatric assessment effect survival in patients with malignant lymphoma

PURPOSE

The prevalence of elderly and comorbid patients (pts) with malignant lymphoma (ML) will steadily increase in future. Elderly patients comprise a heterogeneous population. Comprehensive geriatric assessment (CGA) is an established diagnostic tool in geriatric medicine. However, the prognostic value in patients with ML is unclear. We sought to establish a relationship between results of CGA and survival time in patients with ML.

METHODS

Newly diagnosed patients with ML and indication for chemotherapeutical treatment were prospectively recruited in an observational trial. In addition to usual diagnostic work up, a CGA including activities of daily living (ADL), instrumental activities of daily living (IADL) and comorbidities was performed. Association of patients' characteristics and results of CGA with survival were analysed according to Kaplan-Meier method and in a multivariate Cox-regression analysis.

RESULTS

About 143 patients were included, median age was 63 years, 63 patients were women. Median follow-up of surviving patients was 62 months. Sixty-six patients died within this time. Advanced age, poor Karnofsky performance status, dependence in ADL and IADL and presence of severe comorbidity were significantly associated with shorter survival time. In a Cox-regression analysis, IADL (HR 2.1; 95% CI 1.1-3.9) and comorbidity (HR 1.9; 95% CI 0.9-3.9) were independent and strongest associated with survival time.

CONCLUSION

Results of CGA, such as IADL and comorbidities, are prognostic variables for survival of patients with ML. Results should be validated in homogeneous clinical groups and if confirmed included in diagnostic and therapeutic algorithm.

Deciding to use the emergency room: a qualitative survey of older veterans

Increasing use in the past decade has created pressure for hospital emergency rooms (ERs). Healthcare provided through an ER is expensive and is not designed to meet the complex needs of an older, chronically-ill population. ER visits are presented as the outcome of a decision-making process. Thirty veterans who had visited the ER in the previous year were asked about their decisions to use the ER. Their responses reflected four distinct approaches to ER use, which are characterized by frequency (frequent/infrequent) and risk for social isolation (low/high). Appropriate interventions by social work personnel might reduce inappropriate use of the ER and enhance the care of this vulnerable population.

Improvement of quality of life in hospitalized depressed elderly

BACKGROUND

Quality of life is important for all individuals, but is frequently overlooked in psychiatric populations. Our purpose was to assess the quality of life (QOL) of depressed psychiatrically hospitalized elderly patients, examine the association of QOL and depression, and explore any QOL differences related to electroconvulsive therapy (ECT).

METHODS

This Institutional Review Board (IRB)-approved prospective study recruited geropsychiatric inpatients aged 65 years and older who were depressed, had Mini-mental State Examination (MMSE) scores >18/30, and adequate communication skills. Surveys were completed upon admission and discharge to measure depression (Hamilton Depression Rating Scale (HDRS)), quality of life (Linear Analogue Scales of Assessment (LASA); Medical Outcomes Short Form-36 Health Survey (SF-36)), cognitive function (MMSE; Executive Interview (EXIT 25)), and coping (Brief COPE Inventory (COPE)). Spearman correlations and Wilcoxon signed rank tests were used to assess changes in measures during hospitalization and relationships among variables.

RESULTS

The 45 study participants who completed the study had a mean age of 74 years. The majority were female (67%), married (58%), Protestant (60%), with at least high school education (78%). Admission scores demonstrated severe depression (HDRS 24.88 ± 10.14) and poor QOL (LASA overall QOL 4.4 ± 2.79, and SF-36 mental [27.68 ± 9.63] and physical [46.93 ± 10.41] component scores). At discharge, there was a significant improvement of depression (HDRS 24.88v12.04, p < 0.0001) and QOL (LASA overall QOL 4.4v6.66, p < 0.0001; and SF-36 mental [27.68v39.10, p < 0.0001] and physical [46.93v50.98, p = 0.003] component scores). Not surprisingly, depression was negatively correlated with overall QOL, mental well-being, physical well-being, and emotional well-being at both admission and discharge. For the group who received ECT, there was a greater magnitude of improvement in SF-36 vitality (p = 0.002) and general health perception (p = 0.04), but also a reduction in EXIT 25 scores at discharge (p = 0.008).

CONCLUSIONS

There was improvement of both QOL and depression during the course of hospitalization. Additionally, improvement of QOL was associated with improvement of depression. Perhaps future studies could develop interventions to improve both mood and QOL in elderly depressed inpatients.

Acceptance and Commitment Therapy for generalized anxiety disorder in older adults: a preliminary report

Some evidence suggests that acceptance-based approaches such as Acceptance and Commitment Therapy (ACT) may be well-suited to geriatric generalized anxiety disorder (GAD). The primary goal of this project was to determine whether ACT was feasible for this population. Seven older primary-care patients with GAD received 12 individual sessions of ACT; another 9 were treated with cognitive-behavioral therapy. No patients dropped out of ACT, and worry and depression improved. Findings suggest that ACT may warrant a large-scale investigation with anxious older adults.
