Clinical and health services relationships between major depression, depressive symptoms, and general medical illness

Lifetime depression and anxiety increase prevalent psychological symptoms and worsen glycemic control in type 2 diabetes: The Fremantle Diabetes Study Phase II

AIMS

To determine the contribution of lifetime major depressive disorder (L-MDD) and lifetime generalized anxiety disorder (L-GAD) to current psychological symptom severity, health behaviour and glycaemic control in type 2 diabetes.

METHODS

1285 community-dwelling people with type 2 diabetes (Fremantle Diabetes Study Phase-II; FDS2) completed the PHQ-9 and Brief Life-Time Depression Scale (BLDS) to assess current and past MDD. The Generalized Anxiety Disorder Scale (GADS) and the Generalized Anxiety Disorder Scale-Lifetime (GAD-LT), designed for FDS2, assessed current and past anxiety. Data were analysed using analysis of covariance and multiple mediation models, controlling for age, gender, marital status, and diabetes duration.

RESULTS

L-MDD and L-GAD were independently associated with more severe current depression (both P<0.001) and anxiety (both P<0.001) symptoms. Mediation models revealed that, through increasing the severity of current depressive symptoms, L-MDD was associated with higher HbA_1c and body mass index (BMI), greater likelihood of current smoking, and reduced self-monitoring of blood glucose (SMBG) (indirect regression path ab, all P<0.001). In combination, L-MDD+L-GAD additionally elevated the risk of higher HbA_1c and worse diabetes management, by increasing the severity of current depressive symptoms (indirect regression path ab, all P<0.001).

CONCLUSIONS

Lifetime depression and anxiety increase risk of more severe psychological symptoms, hyperglycaemia, and difficulties with health behaviour in type 2 diabetes. Early screening for these disorders at diabetes diagnosis may be warranted to maximize long-term health outcomes.

Dysphoria is a risk factor for depression in medically ill older people

OBJECTIVES

Depression in older people is commonly under diagnosed and is associated with increased morbidity and mortality. Because older people currently occupy 65% of acute hospital beds, it is crucial for them to be properly assessed for depression to optimise their medical care. The aim of this study was to identify potential risk factors for depression in the medically ill in order to improve their inpatient care.

METHODS

This was a 2-year observational study of consequent referrals to the Newcastle Liaison Team for Older Adults. Out of a total number of 1586 referred patients, 1197 were included in the final analysis of data. Information about their age, main medical history, cognitive impairment and use of antidepressants was collected. All subjects were screened for dementia, depression and delirium. Proportions were compared using the chi-squared test. Clinical depression as a binary variable was modelled using logistic regression.

RESULTS

Higher risk for depression was associated with pain (odds ratio (OR) = 1.76; p = 0.033) and a previous history of depression (OR = 2.22; p < 0.001). Cognitive impairment (OR = 0.44, p < 0.001) and delirium (OR = 0.49; p < 0.001) decreased the likelihood for having depression. Subjective feelings of emptiness, being unhappy and depressed alone (R²  = 37.4%) and cognitive impairment (R²  = 39.5%) were the best multivariable model to explain depression in medically ill people.

Diabetic peripheral neuropathic pain is a stronger predictor of depression than other diabetic complications and comorbidities

AIMS

To investigate the independent effect on depression of painless diabetic polyneuropathy, painful diabetic polyneuropathy, and general and diabetes-related comorbidities.

METHODS

In 181 patients, the presence of painless diabetic polyneuropathy, painful diabetic polyneuropathy, comorbidities and depression was assessed using the Michigan Neuropathy Screening Instrument Questionnaire, the Michigan Diabetic Neuropathy Score, nerve conduction studies, the Douleur Neuropathique en 4 Questions, the Charlson Comorbidity Index and the Beck Depression Inventory-II.

RESULTS

In all, 46 patients met the criteria of confirmed painless diabetic polyneuropathy and 25 of painful diabetic polyneuropathy. Beck Depression Inventory-II scores indicative of mild-moderate-severe depression were reached in 36 patients (19.7%). In a multiple logistic regression analysis (including age, sex, body mass index, being unemployed, duration, haemoglobin A1c, insulin treatment, systolic blood pressure, nephropathy, retinopathy, Charlson Comorbidity Index and painful diabetic polyneuropathy), female sex (odds ratio: 5.9, p = 0.005) and painful diabetic polyneuropathy (odds ratio: 4.6, p = 0.038) were the only independent predictors of depression. Multiple regression analysis, including Douleur Neuropathique en 4 Questions and Michigan Diabetic Neuropathy Score instead of painful diabetic polyneuropathy, showed that Douleur Neuropathique en 4 Questions, in addition to female sex, was a significant predictor of depressive symptoms severity (p =0.005).

CONCLUSION

Painful diabetic polyneuropathy is a greater determinant of depression than other diabetes-related complications and comorbidities. Painful symptoms enhance depression severity more than objective insensitivity.

The overlap of somatic, anxious and depressive syndromes: A population-based analysis

OBJECTIVE

The comorbidity of somatic, anxious and depressive syndromes occurs in half of all primary care cases. As research on this overlap of syndromes in the general population is scarce, the present study investigated the prevalence of the overlapping syndromes and their association with health care use.

METHOD

A national general population survey was conducted between June and July 2012. Trained interviewers contacted participants face-to-face, during which, individuals reported their health care use in the previous 12months. Somatic, anxious and depressive syndromes were assessed using the Somatic Symptom Scale-8 (SSS-8), Generalized Anxiety Disorder-2 (GAD-2) and Patient Health Questionnaire-2 (PHQ-2) respectively.

RESULTS

Out of 2510 participants, 236 (9.4%) reported somatic (5.9%), anxious (3.4%) or depressive (4.7%) syndromes, which were comorbid in 86 (3.4%) cases. The increase in the number of syndromes was associated with increase in health care visits (no syndrome: 3.18 visits vs. mono syndrome: 5.82 visits vs. multi syndromes: 14.16 visits, (F_(2,2507)=149.10, p<0.00001)). Compared to each somatic (semi-partial r²=3.4%), anxious (semi-partial r²=0.82%) or depressive (semi-partial r²=0.002%) syndrome, the syndrome overlap (semi-partial r²=6.6%) explained the greatest part of variance of health care use (_{change_in}R²⁼11.2%, _{change_in}F_(3,2499)=112.81, p<0.001.) CONCLUSIONS: The overlap of somatic, anxious and depressive syndromes is frequent in the general population but appears to be less common compared to primary care populations. To estimate health care use in the general population the overlap of somatic, anxious and depressive syndromes should be considered.

Examining the relationship between physical illness and depression: Is there a difference between inflammatory and non inflammatory diseases? A cohort study

BACKGROUND

There is evidence that inflammation may play a role in the association between physical illness and depression. Our aim was to compare the impact of chronic medical conditions on incidence of depression and to examine if risk of depression varies in terms of the presence and degree of inflammation.

METHODS

This is a secondary analysis conducted within the Spanish sample of the predictD-study.

PARTICIPANTS

5437.

PRIMARY OUTCOME

Incident major depression measured with the Composite International Diagnostic Interview.

EXPOSURE

Presence of chronic medical conditions recorded by GPs using the International Classification of Primary Care, ICPC-2. All analyses were conducted using multivariable logistic regression to allow adjustment for confounders.

RESULTS

The odds of depression are higher in almost all inflammatory than in non-inflammatory illnesses. There is an increasing risk of depression as a consequence of an increasing inflammatory load, with higher odds of depression in the autoimmune group than in the cardio-metabolic group, while both had higher odds of depression than the non-inflammatory groups.

CONCLUSIONS

Inflammation may be part of the pathway by which chronic physical illness leads to depression. Future studies should examine the role of inflammation in the prevention and management of depression.

Pragmatic detection of anxiety and depression in a prospective cohort of voice outpatient clinic attenders

OBJECTIVE

To evaluate diagnostic performance of the emotional domain of the VoiSS questionnaire compared with the Hospital Anxiety and Depression Scale (HADS).

DESIGN

Cross-sectional questionnaire study.

SETTING

Tertiary referral centre voice clinic.

PARTICIPANTS

210 consecutive voice clinic patients.

MAIN OUTCOME MEASURES

Screening with VoiSS and HADS questionnaires. Paired comparison, correlation, multinomial logistic regression and receiver-operating characteristic (ROC) curve analysis.

RESULTS

A total of 177 returned complete data sets. Ninety-six patients (54.2%) had functional dysphonia, and 81 (45.8%) had organic laryngeal disorders. Mean total VoiSS score = 39.7/120 (standard deviation (sd) 22.2). Mean emotional VoiSS subscale = 7.6/22 (sd 7.5). Mean HADS anxiety = 6.5/21 (sd 5.2) and depression mean = 7.1/21 (sd 4.8). There were 35 (20%) borderline anxiety and/or depression scores and 30 (17%) scores considered positive for 'caseness'. There was strong correlation between emotional VoiSS and HADS anxiety (Spearman's Rho = 0.68, P < 0.001) and HADS depression (Spearman's Rho = 0.62, P < 0.001). ROC curve analysis exhibited significant association between emotional VoiSS and HADS 'caseness' (area under curve = 0.88). In addition, functional dysphonia patients had lower mean VoiSS and HADS scores than patients with identifiable laryngeal abnormalities.

CONCLUSION

The VoiSS emotional subscale strongly correlates with HADS anxiety and depression scores and could be used as a measure of psychological distress. This could allow targeted psychological strategies, without additional psychometric questionnaires. Functional dysphonia has less association with psychological distress than certain organic laryngological disorders.

Monotherapy With Major Antihypertensive Drug Classes and Risk of Hospital Admissions for Mood Disorders

Major depressive and bipolar disorders predispose to atherosclerosis, and there is accruing data from animal model, epidemiological, and genomic studies that commonly used antihypertensive drugs may have a role in the pathogenesis or course of mood disorders. In this study, we propose to determine whether antihypertensive drugs have an impact on mood disorders through the analysis of patients on monotherapy with different classes of antihypertensive drugs from a large hospital database of 525 046 patients with follow-up for 5 years. There were 144 066 eligible patients fulfilling the inclusion criteria: age 40 to 80 years old at time of antihypertensive prescription and medication exposure >90 days. The burden of comorbidity assessed by Charlson and Elixhauser scores showed an independent linear association with mood disorder diagnosis. The median time to hospital admission with mood disorder was 847 days for the 299 admissions (641 685 person-years of follow-up). Patients on angiotensin-converting enzyme inhibitors or angiotensin receptor blockers had the lowest risk for mood disorder admissions, and compared with this group, those on β-blockers (hazard ratio=2.11; [95% confidence interval, 1.12-3.98]; P=0.02) and calcium antagonists (2.28 [95% confidence interval, 1.13-4.58]; P=0.02) showed higher risk, whereas those on no antihypertensives (1.63 [95% confidence interval, 0.94-2.82]; P=0.08) and thiazide diuretics (1.56 [95% confidence interval, 0.65-3.73]; P=0.32) showed no significant difference. Overall, our exploratory findings suggest possible differential effects of antihypertensive medications on mood that merits further study: calcium antagonists and β-blockers may be associated with increased risk, whereas angiotensin-converting enzyme inhibitors and angiotensin receptor blockers may be associated with a decreased risk of mood disorders.

Type of Multimorbidity and Patient-Doctor Communication and Trust among Elderly Medicare Beneficiaries

Background. Effective communication and high trust with doctor are important to reduce the burden of multimorbidity in the rapidly aging population of the US. However, the association of multimorbidity with patient-doctor communication and trust is unknown. Objective. We examined the relationship between multimorbidity and patient-doctor communication and trust among the elderly. Method. We used the Medicare Current Beneficiary Survey (2012) to analyze the association between multimorbidity and patient-doctor communication and trust with multivariable logistic regressions that controlled for patient's sociodemographic characteristics, health status, and satisfaction with care. Results. Most elderly beneficiaries reported effective communication (87.5-97.5%) and high trust (95.4-99.1%) with their doctors. The elderly with chronic physical and mental conditions were less likely than those with only physical conditions to report effective communication with their doctor (Adjusted Odds Ratio [95% Confidence Interval] = 0.80 [0.68, 0.96]). Multimorbidity did not have a significant association with patient-doctor trust. Conclusions. Elderly beneficiaries had high trust in their doctors, which was not affected by the presence of multimorbidity. Elderly individuals who had a mental condition in addition to physical conditions were more likely to report ineffective communication. Programs to improve patient-doctor communication with patients having cooccurring chronic physical and mental health conditions may be needed.

The association of unipolar depression with thirty-day mortality after hospitalization for infection: A population-based cohort study in Denmark

OBJECTIVE

While depression is associated with higher risk of death due to chronic medical conditions, it is unknown if depression increases mortality following serious infections. We sought to determine if pre-existing unipolar depression is associated with increased mortality within 30days after hospitalization for a serious infection.

METHODS

We conducted a population-based cohort study of all adults hospitalized for an infection in Denmark between 2005 and 2013. Pre-existing unipolar depression was ascertained via psychiatrist diagnoses or at least two antidepressant prescription redemptions within a six month period. Our primary outcome was all-cause mortality within 30days after infection-related hospitalization. We also studied death due to infection within 30days after admission.

RESULTS

We identified 589,688 individuals who had a total of 703,158 hospitalizations for infections. After adjusting for demographics, infectious diagnosis and time since infection, socioeconomic factors and comorbidities, pre-existing unipolar depression was associated with slightly increased risk of all-cause mortality within 30days after infection-related hospitalization (Mortality Rate Ratio [MRR]: 1.07, 95% Confidence Interval [95% CI]: 1.05, 1.09). The association was strongest among persons who initiated antidepressant treatment within one year before the infection (MRR: 1.30, 95% CI: 1.25, 1.35). Pre-existing unipolar depression was associated with increased risk of death due to sepsis (MRR: 1.30, 95% CI: 1.17, 1.44), pneumonia (MRR: 1.23, 95% CI: 1.16, 1.29) and urinary tract infection (MRR: 1.25, 95% CI: 1.08, 1.44) after adjusting for demographics, infectious diagnosis at admission and time since infection.

CONCLUSIONS

Pre-existing unipolar depression is associated with slightly increased mortality following hospitalization for an infection.

Functioning Among Youth with Comorbid Mood Disorder and Chronic Physical Illness in Public Sector Care

OBJECTIVE

The current study examines parent/caregiver and youth report of psychosocial and health-related functioning among youth served in public systems of care, with mood disorder only, comorbid mood disorder and chronic physical illness, and chronic physical illness only.

METHOD

Participants were 539 youths (ages, 11-18; 64% male) with a mood disorder and/or chronic physical illness enrolled in a study of public sector care. Presence of mood disorder was based on youth report on the Diagnostic Interview Schedule for Children-IV. Parents reported whether they had been told by a school or health professional that their child had 1 of 8 categories of chronic physical illnesses. Psychosocial functioning was assessed with the Child Behavior Checklist and Youth Self Report. Parent and child versions of the Child Health Questionnaire assessed health-related functioning. Covariates included demographic variables, substance use, mental health service utilization, disruptive behavior disorders, and anxiety disorders. Multivariate analysis of covariances assessed differences on outcome measures among the 3 groups.

RESULTS

Parents and youths reported significantly worse psychosocial and health-related functioning for youth with comorbid mood and physical illnesses. Generally, parents reported lower functioning in youth with a physical illness compared with mood disorder, and youth with mood disorders reported lower functioning than those with physical illness.

CONCLUSION

Youth with comorbid mood disorder and chronic physical illness experience high levels of impairment. Increased screening of mood disorders in pediatric health settings is warranted. Health systems, clinics, and clinicians should focus on integrating mental and physical health diagnosis and treatment.

Racial/Ethnic Differences in Predictors of Mental Health Treatment in Persons with Comorbid Diabetes and Depression

Diabetes and depression are two of the most frequently diagnosed health conditions in the United States and often co-occur. The present study examines racial/ethnic differences in predictors of mental health service use among a national sample of African Americans, Hispanics, and non-Hispanic Whites with a self-reported diabetes and depression diagnosis. Multiple logistic regression was used to analyze a cross-sectional sample (N = 3377) of the 2012 National Health Interview Survey (NHIS), a nationally representative, cross-sectional survey. African Americans were less likely to have visited a mental health professional in the last 12 months (odds ratio [OR] = .634, confidence interval [CI] [0.429, 0.911]). Significant odds ratios also uncovered results for the "never married" (OR = 1.737, CI [1.322, 2.281]) category. Also for the entire sample, being 55 years or older (OR = .352, CI [0.234, 0.533]) was found to be strongly associated with mental health service use for individuals with diabetes. Being unemployed or not in the labor force increased the odds of mental health service use in persons with diabetes and depression, whereas having less than a high school diploma or Graduate Equivalency Diploma decreased odds of visits (OR = .611, CI [0.394, 0.945]) as did not having health insurance (OR = .540, CI [0.365, 0.800]). Racial/ethnic variation in mental health service utilization exists among persons with self-reported diabetes and depression. Due to the challenges associated with comorbid depression and diabetes, as well as the impact depression can have on diabetes self-management, it is imperative that more strategies for managing both depression and diabetes be explored.

Psychogenic Explanations of Physical Illness

In some patients with chronic physical complaints, detailed examination fails to reveal a well-recognized underlying disease process. In this situation, the physician may suspect a psychological cause. In this review, we critically evaluated the evidence for this causal claim, focusing on complaints presenting as neurological disorders. There were four main conclusions. First, patients with these complaints frequently exhibit psychopathology but not consistently more often than patients with a comparable “organic” diagnosis, so a causal role cannot be inferred. Second, these patients report a high incidence of adverse life experiences, but again, there is insufficient evidence to indicate a causal role for any particular type of experience. Third, although psychogenic illnesses are believed to be more responsive to psychological interventions than comparable “organic” illnesses, there is currently no evidence to support this claim. Finally, recent evidence suggests that biological and physical factors play a much greater causal role in these illnesses than previously believed. We conclude that there is currently little evidential support for psychogenic theories of illness in the neurological domain. In future research, researchers need to take a wider view concerning the etiology of these illnesses.

Depression in Chronic Kidney Disease and End-Stage Renal Disease: Similarities and Differences in Diagnosis, Epidemiology, and Management

Depression is highly prevalent and is associated with poor quality of life and increased mortality among adults with chronic kidney disease (CKD), including those with end-stage renal disease (ESRD). However, there are several important differences in the diagnosis, epidemiology, and management of depression between patients with non-dialysis-dependent CKD and ESRD. Understanding these differences may lead to a better understanding of depression in these 2 distinct populations. First, diagnosing depression using self-reported questionnaires may be less accurate in patients with ESRD compared with CKD. Second, although the prevalence of interview-based depression is approximately 20% in both groups, the risk factors for depression may vary. Third, potential mechanisms of depression might also differ in CKD versus ESRD. Finally, considerations regarding the type and dose of antidepressant medications vary between CKD and ESRD. Future studies should further examine the mechanisms of depression in both groups, and test interventions to prevent and treat depression in these populations.

Healthcare Utilization and Expenditures for Persons with Diabetes Comorbid with Mental Illnesses

The aim of this study was to investigate healthcare utilization and expenditure for patients with diabetes comorbid with and without mental illnesses in Taiwan. People with diabetes comorbid with and without mental illnesses in 2000 were identified and followed up to 2004 to explore the healthcare utilization and expenditure. Healthcare utilization included outpatient visits and use of hospital inpatient services, and expenditure included outpatient, inpatient and total medical expenditure. General estimation equation models were used to explore the factors associated with outpatient visits and expenditure. To identify the factors associated with hospitalization, multiple logistic regressions were applied. The average number of annual outpatient visits of the patients with mental illnesses ranged from 37.01 to 41.91, and 28.83 to 31.79 times for the patients without mental illnesses from 2000 to 2004. The average annual total expenditure for patients with mental illnesses during this period ranged from NT$77,123-NT$90,790, and NT$60,793- NT$84,984 for those without mental illnesses. After controlling for covariates, the results indicated that gender, age, mental illness and time factor were associated with outpatient visits. Gender, age, and time factor were associated with total expenditure. Age and mental illness were associated with hospitalization in logistic regression. The healthcare utilization and expenditure for patients with mental illnesses was significantly higher than for patients without mental illnesses. The factors associated with healthcare utilization and expenditure included gender, age, mental illness and time trends.

Pre-surgical depression and anxiety and recovery following coronary artery bypass graft surgery

We aimed to explore the combined contribution of pre-surgical depression and anxiety symptoms for recovery following coronary artery bypass graft (CABG) using data from 251 participants. Participants were assessed prior to surgery for depression and anxiety symptoms and followed up at 12 months to assess pain and physical symptoms, while hospital emergency admissions and death/major adverse cardiac events (MACE) were monitored on average 2.68 years after CABG. After controlling for covariates, baseline anxiety symptoms, but not depression, were associated with greater pain (β = 0.231, p = 0.014) and greater physical symptoms (β = 0.194, p = 0.034) 12 months after surgery. On the other hand, after controlling for covariates, baseline depression symptoms, but not anxiety, were associated with greater odds of having an emergency admission (OR 1.088, CI 1.010–1.171, p = 0.027) and greater hazard of death/MACE (HR 1.137, CI 1.042–1.240, p = 0.004). These findings point to different pathways linking mood symptoms with recovery after CABG surgery.

Seeking an objective diagnosis of depression

Major depressive disorder (MDD: unipolar depression) is widely distributed in the USA and world-wide populations and it is one of the leading causes of disability in both adolescents and adults. Traditional diagnostic approaches for MDD are based on patient interviews, which provide a subjective assessment of clinical symptoms which are frequently shared with other maladies. Reliance upon clinical assessments and patient interviews for diagnosing MDD is frequently associated with misdiagnosis and suboptimal treatment outcomes. As such, there is increasing interest in the identification of objective methods for the diagnosis of depression. Newer technologies from genomics, transcriptomics, proteomics, metabolomics and imaging are technically sophisticated and objective but their application to diagnostic tests in psychiatry is still emerging. This brief overview evaluates the technical basis for these technologies and discusses how the extension of their clinical performance can lead to an objective diagnosis of MDD.

Anxiety and physical health problems increase the odds of women having more severe symptoms of depression

Severely depressed women incur substantial disability and suicide risk, necessitating an understanding of factors that may contribute to severe depression. The purpose of this research was to determine the degree to which age, physical morbidity, anxiety, and hormonal status predict the likelihood of severe depression among women with mood disorders (n = 298). Data arose from a standardized battery of measures in a multi-center clinical registry of patients with mood disorders. The women were being treated at 17 participating sites of the National Network of Depression Centers. Results of logistic regression analyses indicate that a woman's level of anxiety was the strongest predictor of her likelihood of having severe depression (Exp(B) = 1.33, p = .000), including thoughts of death or suicide. The number of physical health problems that a woman reported was also a significant predictor (Exp(B) = 1.09, p = .04). Neither age nor hormonal status was significant in the final model, although a trend was observed for women with surgically induced menopause to have more severe depression. Findings support the need to work closely with medical practitioners to address physical health problems as part of the treatment plan for depression and to give comorbid anxiety and depression equal priority in symptom management.

Internalizing disorders in adults with a history of childhood traumatic brain injury

INTRODUCTION

While the presence of externalizing behavioral problems following traumatic brain injury (TBI) has been well established in the literature, less is known regarding internalizing disorders, and more specifically anxiety disorders, in such a population. This study explored the presence, rate, and incidence of internalizing behavior problems, including anxiety, depression, somatic complaints, avoidant personality symptomatology, and overall internalizing behavior problems in university students aged 18-25 years.

METHOD

A convenience sample of 247 university students (197 non-TBI, 47 mild TBI, 2 moderate TBI, 1 severe TBI) aged 18-25 years was utilized. Participants completed a self-report measure on behavioral functioning, the Adult Self Report (ASR), to identify internalizing behaviors, and a questionnaire to identify TBI history.

RESULTS

Raw scores of behavior indicated that participants with a history of childhood TBI reported significantly higher levels of withdrawal, somatic complaints, and internalizing behavioral problems than the non-TBI participants. When analyzing standardized T-scores for borderline and clinically elevated ASR syndromes and Diagnostic and Statistical Manual of Mental Disorders (DSM)-oriented scales, individuals in the TBI group were significantly more likely to have higher rates of borderline anxiety, somatic complaints, avoidant personality problems, and overall internalizing disorders, and clinically elevated somatic complaints. Adults with a history of childhood TBI were also significantly more likely to report at least 1 or more DSM disorders.

CONCLUSION

These results clearly suggest that individuals with a childhood history of TBI are at a heightened risk for a range of internalizing disorders in early adulthood, which is particularly troubling in a university sample pursuing tertiary education.

Predictors and outcomes of sustained, intermittent or never achieving remission in patients with recent onset inflammatory polyarthritis: results from the Norfolk Arthritis Register

OBJECTIVES

Early remission is the current treatment strategy for patients with inflammatory polyarthritis (IP) and RA. Our objective was to identify baseline factors associated with achieving remission: sustained (SR), intermittent (IR) or never (NR) over a 5-year period in patients with early IP.

METHODS

Clinical and demographic data of patients with IP recruited to the Norfolk Arthritis Register (NOAR) were obtained at baseline and years 1, 2, 3 and 5. Remission was defined as no tender or swollen joints (out of 51). Patients were classified as NR or PR, respectively, if they were in remission at: no assessment or ⩾3 consecutive assessments after baseline, and IR otherwise. Ordinal regression and a random effects model, respectively, were used to examine the association between baseline factors, remission group and HAQ scores over time.

RESULTS

A total of 868 patients (66% female) were included. Of these, 54%, 34% and 12% achieved NR, IR and SR, respectively. In multivariate analysis, female sex (odds ratio, OR 0.47, 95% CI: 0.35, 0.63), higher tender joint count (OR = 0.94, 95% CI: 0.93, 0.96), higher HAQ (OR = 0.59, 95% CI: 0.48, 0.74), being obese (OR = 0.70, 95% CI: 0.50, 0.99), hypertensive (OR = 0.67, 95% CI: 0.50, 0.90) or depressed (OR = 0.74, 95% CI: 0.55, 1.00) at baseline were independent predictors of being in a lower remission group. IR and SR were associated with lower HAQ scores over time and lower DAS28 at year 5.

CONCLUSION

Women with higher tender joint count and disability at baseline, depression, obesity and hypertension were less likely to achieve remission. This information could help when stratifying patients for more aggressive therapy.

Effects of Comorbid Depression and Diabetes Mellitus on Cognitive Decline in Older Mexican Americans

OBJECTIVES

To assess the relationship between comorbid depression, diabetes mellitus (DM), and cognitive decline in Mexican Americans aged 65 and older.

DESIGN

Retrospective cohort study with longitudinal analysis.

SETTING

Texas, New Mexico, Colorado, Arizona, and California.

PARTICIPANTS

Hispanic Established Populations for the Epidemiologic Study of the Elderly.

MEASUREMENTS

Cognition was assessed using the Mini-Mental State Examination (MMSE). Depression was defined as a score of 16 or greater on the Center for Epidemiologic Studies Depression Scale. DM was defined as according to self-reported history or taking insulin or oral hypoglycemic medication.

RESULTS

Participants with depression and DM declined an average of 6.5 points on the MMSE; depression only, 4.4 points; DM only, 7.8 points; and neither condition, 4.2 points across the six examination waves. Participants with DM declined an average of 0.18 more points on the MMSE per year (P=.001) than those with neither DM nor depression, and those with comorbid DM and depression declined 0.25 more points per year (P=.002). Depression was associated with significantly greater cognitive decline (β^=-0.11, P=.05) after excluding participants with baseline cognitive impairment (MMSE score≤17). Participants with DM were 1.08 (95% CI=1.03-1.12) times as likely as those with neither DM nor depression, and those with comorbid DM and depression were 1.08 (95% CI=1.01-1.15) times as likely as those with neither DM nor depression to develop severe cognitive impairment per year.

CONCLUSION

DM and comorbid depression and DM are risk factors for cognitive decline in older Mexican Americans. Interventions that reduce the prevalence of depression and DM in Mexican Americans may decrease the number of older adults who experience cognitive decline.

Depression and anxiety among elderly earthquake survivors in China

This study investigated depression and anxiety among Chinese elderly earthquake survivors, addressing relevant correlations. We sampled one earthquake-prone city, utilising the Geriatric Depression Scale and Beck Anxiety Inventory. In addition, explorative factor analysis and structural equation model methods were used. Results indicated elderly earthquake survivors exhibited symptoms of moderate depression and anxiety; depression and anxiety are highly positively correlated. The overlap between these two psychological problems may be due to subjective fear and motoric dimensions; subjective fear and motoric dimensions of Beck Anxiety Inventory are more strongly related to Geriatric Depression Scale domains. The two scales exhibit high reliability and validity.

Effectiveness of Cognitive Behavioural Self-Help for the Treatment of Depression and Anxiety in People with Long-Term Physical Health Conditions: a Systematic Review and Meta-Analysis of Randomised Controlled Trials

BACKGROUND

Depression and anxiety are prevalent comorbidities in people with long-term physical health conditions; however, there is limited access to evidence-based treatments for comorbid mental health difficulties.

PURPOSE

This study is a meta-analysis examining the effectiveness of cognitive behavioural self-help for physical symptoms, depression and anxiety in people with long-term conditions.

METHODS

This study involves a systematic search of electronic databases supplemented by expert contact, reference and citation checking and grey literature.

RESULTS

The meta-analysis yielded a small effect size for 11 studies reporting primary outcomes of depression (g = -0.20) and 8 studies anxiety (g = -0.21) with a large effect size (g = -1.14) for 1 study examining physical health symptoms. There were no significant moderators of the main effect.

CONCLUSIONS

Limited evidence supports cognitive behavioural self-help for depression, anxiety and physical symptoms in people with long-term conditions. Small effect sizes for depression and anxiety may result from failure to recruit participants with clinical levels of these difficulties at baseline.

Depression and cholesteatoma: Preliminary findings from a nationwide population-based retrospective cohort study

OBJECTIVE

To estimate the risk of developing depressive disorder (DD) following diagnosis with cholesteatoma.

METHODS

In the study, we analyzed data from the Longitudinal Health Insurance Database of Taiwan. A total of 599 patients newly diagnosed with cholesteatoma between 1997 and 2007 were included with a comparison cohort of 2995 matched non-cholesteatoma enrollees. Each patient was followed for 3 years to identify the subsequent development of DD. Cox proportional hazard regression analysis was performed to compute adjusted 3-year hazard ratios.

RESULTS

The incidence of DD per thousand person-years was approximately twice as high among patients with cholesteatoma (11.32) as among those without cholesteatoma (5.85). After adjusting for potential confounders, patients with cholesteatoma were 1.99 times (95% CI=1.18-3.34, P=0.010) more likely to suffer from DD within 3 years compared to those without cholesteatoma.

CONCLUSIONS

This is the first study to demonstrate a link between cholesteatoma and subsequent DD within a three-year followup. We suggest that clinicians keep this critical but neglected issue in mind and carefully investigate the possibility of subsequent psychological problems among cholesteatoma patients.

Depressive symptoms impact health-promoting lifestyle behaviors and quality of life in healthy women

BACKGROUND

Depressive symptoms are an independent risk factor of cardiovascular disease (CVD). More than 15% of persons with CVD have depressive symptoms, which are twice as likely to occur in women. Depressive symptoms in women being screened for CVD have not been well studied.

OBJECTIVE

The relationships between depressive symptoms, health-promoting lifestyle behaviors, heart disease risk awareness, cardiac risk, and quality of life (QOL) in women were investigated. Whether the effect of depressive symptoms on QOL was mediated by cardiac risk and/or health-promoting lifestyle behaviors was also examined.

METHODS

The Wilson-Cleary Health-Related Quality of Life Model guided this descriptive study. A convenience sample of 125 women was recruited from cardiac health screening events. The study measurements were the Center for Epidemiologic Studies Depression Scale; the Framingham risk score; the Ferrans-Powers Quality of Life Index Generic Version-III; the Health-Promoting Lifestyle Profile-II; and questions related to heart disease risk, awareness of heart disease risk, health history, and demographics. Body mass index, percentage of body fat, and lipid profile were also measured.

RESULTS

More than one-third (34%) of the women reported significant depressive symptoms. Depressive symptoms were not associated with cardiac risk or risk awareness but were inversely associated with health-promoting lifestyle behaviors (r = -0.37, P < 0.01) and QOL (r = -0.51, P < 0.01). There was a dose-response relationship with health-promoting lifestyle behaviors (odds ratio, 0.92; 95% confidence interval, 0.88-0.97; P < 0.001) and QOL (odds ratio, 0.85; 95% confidence interval, 0.79-0.92; P < 0.001) and depressive symptoms. Health-promoting lifestyle behaviors mediated the association between depressive symptoms and QOL.

CONCLUSIONS

Depressive symptoms contribute significantly to health-promoting lifestyle behaviors and QOL for women. Early detection and treatment of depressive symptoms are important for participation in healthy lifestyle behaviors, which could result in improved QOL.

The relationship between depression and frailty syndrome: a systematic review

OBJECTIVES

Frailty is a geriatric syndrome characterised by the clinical presentation of identifiable physical alterations such as loss of muscle mass and strength, energy and exercise tolerance, and decreased physiological reserve. Frailty and depressive symptoms are common issues facing older adults and may be associated. It is not clear if the depression facilitates the appearance of frailty syndrome or vice versa or these two coexist independently in the same individuals.

METHOD

We performed searches in several databases (Embase, PubMed, CINAHL, Scopus, and PsycINFO) papers published between November 2003 to February 2014 about frailty syndrome and depression in people aged 65 and older published and the reference lists of from the articles retrieved were pearled in order to identify any which may have been missed in the initial search. Two independent reviewers extracted descriptive information on the prevalence and co-occurrence of frailty and depression in older individuals and of frailty criteria among depressed patients.

RESULTS

Depression and frailty occur in a significant proportion of frail older individuals. Common pathophysiological alterations and biomarkers in the two syndromes have been recently described.

CONCLUSION

Studies on the causal relationship between the two syndromes are clearly necessary in the future.

Construct Validity of the SF-12v2 for the Homeless Population with Mental Illness: An Instrument to Measure Self-Reported Mental and Physical Health

BACKGROUND

Self-reported health measures are important indicators used by clinicians and researchers for the evaluation of health interventions, outcome assessment of clinical studies, and identification of health needs to improve resource allocation. However, the application of self-reported health measures relies on developing reliable and valid instruments that are suitable across diverse populations. The main objective of this study is to evaluate the construct validity of the SF-12v.2, an instrument for measuring self-rated physical and mental health, for homeless adults with mental illness. Various interventions have been aimed at improving the health of homeless people with mental illness, and the development of valid instruments to evaluate these interventions is imperative.

STUDY DESIGN

We measured self-rated mental and physical health from a quota sample of 575 homeless people with mental illness using the SF-12v2, EQ-5D, Colorado Symptoms Index, and physical/mental health visual analogue scales. We examined the construct validity of the SF-12v2 through confirmatory factor analyses (CFA), and using ANOVA/correlation analyses to compare the SF-12v2 to the other instruments to ascertain discriminant/convergent validity.

RESULTS

Our CFA showed that the measurement properties of the original SF-12v2 model had a mediocre fit with our empirical data (χ2 = 193.6, df = 43, p < .0001, CFI = 0.85, NFI = 0.83, RMSEA = 0.08). We demonstrate that changes based on theoretical rationale and previous studies can significantly improve the model, achieving an excellent fit in our final model (χ2 = 160.6, df = 48, p < .0001, CFI = 0.95, NFI = 0.95, RMSEA = 0.06). Our CFA results suggest that an alternative scoring method based on the new model may optimize health status measurement of a homeless population. Despite these issues, convergent and discriminant validity of the SF-12v2 (scored based on the original model) was supported through multiple comparisons with other instruments.

CONCLUSION

Our study demonstrates for the first time that the SF-12v2 is generally appropriate as a measure of physical and mental health status for a homeless population with mental illness.

Excess mortality due to depression and anxiety in the United States: results from a nationally representative survey

OBJECTIVES

We compared the mortality of persons with and without anxiety and depression in a nationally representative survey and examined the role of socioeconomic factors, chronic diseases and health behaviors in explaining excess mortality.

METHODS

The 1999 National Health Interview Survey was linked with mortality data through 2011. We calculated the hazard ratio (HR) for mortality by presence or absence of anxiety/depression and evaluated potential mediators. We calculated the population attributable risk of mortality for anxiety/depression.

RESULTS

Persons with anxiety/depression died 7.9 years earlier than other persons. At a population level, 3.5% of deaths were attributable to anxiety/depression. Adjusting for demographic factors, anxiety/depression was associated with an elevated risk of mortality [HR=1.61, 95% confidence interval (CI)=1.40, 1.84]. Chronic diseases and health behaviors explained much of the elevated risk. Adjusting for demographic factors, people with past-year contact with a mental health professional did not demonstrate excess mortality associated with anxiety/depression while those without contact did.

CONCLUSIONS

Anxiety/depression presents a mortality burden at both individual and population levels. Our findings are consistent with targeting health behaviors and physical illnesses as strategies for reducing this excess mortality among people with anxiety/depression.

Universal structures of normal and pathological heart rate variability

The circulatory system of living organisms is an autonomous mechanical system softly tuned with the respiratory system, and both developed by evolution as a response to the complex oxygen demand patterns associated with motion. Circulatory health is rooted in adaptability, which entails an inherent variability. Here, we show that a generalized N-dimensional normalized graph representing heart rate variability reveals two universal arrhythmic patterns as specific signatures of health one reflects cardiac adaptability, and the other the cardiac-respiratory rate tuning. In addition, we identify at least three universal arrhythmic profiles whose presences raise in proportional detriment of the two healthy ones in pathological conditions (myocardial infarction; heart failure; and recovery from sudden death). The presence of the identified universal arrhythmic structures together with the position of the centre of mass of the heart rate variability graph provide a unique quantitative assessment of the health-pathology gradient.

Self-perceived Mental Health Status and Uptake of Fecal Occult Blood Test for Colorectal Cancer Screening in Canada: A Cross-Sectional Study

BACKGROUND

While colorectal cancer (CRC) is one of the most preventable causes of cancer mortality, it is one of the leading causes of cancer death in Canada where CRC screening uptake is suboptimal. Given the increased rate of mortality and morbidity among mental health patients, their condition could be a potential barrier to CRC screening due to greater difficulties in adhering to behaviours related to long-term health goals. Using a population-based study among Canadians, we hypothesize that self-perceived mental health (SPMH) status and fecal occult blood test (FOBT) uptake for the screening of CRC are associated.

METHODS

The current study is cross-sectional and utilised data from the Canadian Community Health Survey 2011-2012. Multinomial logistic regression analysis was undertaken to assess whether SPMH is independently associated with FOBT uptake among a representative sample of 11 386 respondents aged 50-74 years.

RESULTS

Nearly half of the respondents reported having ever had FOBT for CRC screening, including 37.28% who have been screened within two years of the survey and 12.41% who had been screened more than two years preceding the survey. Respondents who reported excellent mental health were more likely to have ever been screened two years or more before the survey (adjusted odds ratio [AOR] = 2.08; 95% CI, 1.00-4.43) and to have been screened in the last two years preceding the survey (AOR = 1.53; 95% CI, 0.86-2.71) than those reported poor mental health status.

CONCLUSION

This study supports the association between SPMH status and FOBT uptake for CRC screening. While the efforts to maximize CRC screening uptake should be deployed to all eligible people, those with poor mental health may need more attention.

Childhood Sexual Abuse Moderates the Relationship Between Obesity and Mental Health in Low-Income Women

We examined whether a history of self-reported childhood sexual abuse (CSA) moderates the relationship between obesity and mental health symptoms (depression, anxiety, and posttraumatic stress disorder) in an ethnically diverse sample of low-income women. A community sample of 186 women completed self-report measures and had their weight and height measured. Body mass index and CSA had an interactive effect on all mental health measures, such that obese women with a CSA history reported substantially higher levels of all symptoms. These results give greater specificity to the obesity-mental health link reported in previous studies and provide possible directions for targeted intervention.

Factors impacting on patient perception of procedural success and satisfaction following treatment for varicose veins

Background

Patient-reported outcome measures (PROMs) have been collected from patients undergoing varicose vein treatments in the National Health Service since 2009. The aim of this retrospective cohort study was to examine PROMs for varicose vein interventions, characterizing factors that might predict patient-reported perception of procedural success and satisfaction.

Methods

Centrally compiled PROMs data for varicose vein procedures carried out from 2009 to 2011 were obtained from the Hospital Episode Statistics data warehouse for England. As data were not distributed normally, non-parametric statistical tests were employed.

Results

Data for 35 039 patient episodes (62·8 per cent women) were available for analysis. Some 23·4 per cent of patients reported a degree of anxiety or depression before treatment; a formal diagnosis of depression was present in 7·8 per cent. Quality of life, measured by generic EQ-5D-3L™ index and the Aberdeen Varicose Vein Questionnaire (AVVQ) improved after intervention by 11·7 per cent (0·77 to 0·86) and 40·1 per cent (18·95 to 11·36) respectively. No significant improvement was found in EQ-5D™ visual analogue scale scores. There was a significant improvement in self-perceived anxiety or depression after the intervention (P &lt; 0·001, McNemar–Bowker test). Both preoperative and postoperative depression or anxiety had a statistically significant relationship with self-reported success and satisfaction (both P &lt; 0·001, χ2 test).

Conclusion

This analysis of PROMs is evidence that treatment of varicose veins improves quality of life, and anxiety or depression. Preoperative and postoperative anxiety or depression scores impact on patient-perceived success and satisfaction rates.

Health-related quality of life mediates associations between multi-morbidity and depressive symptoms in Chinese primary care patients

BACKGROUND

Qualifying the relationship between multi-morbidity, health-related quality of life (HRQOL) and depressive symptoms in primary care can help to inform the development of appropriate interventions and services which can help to enhance HRQOL in patients with chronic disease.

OBJECTIVE

The objective of this study was to determine whether the physical aspect of HRQOL mediates the relationship between chronic disease multi-morbidity and depressive symptoms in Chinese primary care patients.

METHODS

A cross-sectional survey was conducted on patients recruited from the waiting rooms of 59 primary care clinics distributed across Hong Kong. About 9259 subjects were included for the mediation model analysis. The primary outcome was level of depressive symptoms as measured by the Patient Health Questionniare 9. The mediation model was tested using a bootstrapping method.

RESULTS

The prevalence of chronic disease was 50.4%, with 25.4% having two or more co-morbidities. The relationship between multi-morbidity and depressive symptoms was found to be mediated by the Physical Component Summary score of the SF-12 v2. Further analysis found the general health (GH) and role physical domains of the SF-12 were the strongest mediators, followed by bodily pain and physical functioning (PF).

CONCLUSION

To enhance the functional capacity of primary care patients with co-existing chronic disease and depressive symptoms, health care interventions should be directed at improving the physical aspects of HRQOL, in particular enhancing patients' GH perception, role functioning and PF, and to better manage chronic pain.

Disease Control Among Patients With Diabetes and Severe Depressive Symptoms

OBJECTIVE

Major depressive disorder and type 2 diabetes commonly co-occur and disease control tends to be poorer when both conditions are present. However, little research has examined the disease characteristics of patients with diabetes and more severe depressive symptoms.

METHODS

We report a retrospective observational study of 517 patients with diabetes from 2 primary care centers. Patients with diabetes and moderately-severe/severe depression symptoms (Patient Health Questionnaire [PHQ-9] score >15) were compared with patients with diabetes without moderate or severe depression symptoms (PHQ-9 score <15; the comparison group) with regard to control of diabetes, blood pressure, and lipid parameters. Frequency of HbA1c and PHQ-9 testing were also examined.

RESULTS

Patients with diabetes and moderately severe/severe depressive symptoms had higher HbA1c (7.56% vs. 7.09%), diastolic blood pressure (78.43 vs. 75.67 mm Hg), and low-density lipoprotein cholesterol (109.12 vs. 94.22 mg/dL) versus the comparison group. Patients with diabetes and moderately-severe/severe depression underwent HbA1c and PHQ-9 testing with similar frequency to the comparison group.

CONCLUSIONS

The presence of moderately severe/severe depressive symptoms was associated with poorer glucose, lipid, and blood pressure control among patients with diabetes. Further research should prospectively examine whether a targeted depression treatment goal (PHQ-9 score <15) in patients with diabetes results in improved control of these important disease parameters.

What factors contribute to the risk of depression in epilepsy?--Tasmanian Epilepsy Register Mood Study (TERMS)

OBJECTIVE

To model the factors associated with depression in a community sample of people with epilepsy. The factors investigated were derived from proposed risk factors for depression from patients with epilepsy, other chronic illness, and the general population.

METHODS

Multivariate analysis using general linear regression models of factors associated with depression in the Tasmanian Epilepsy Register Mood Study (TERMS), a cross-sectional community sample of 440 patients with epilepsy.

RESULTS

A model with acceptable fit was created that explained 66% of the variance of depression. Associated factors included in this model were neuroticism, physical functioning, social support, past history of depression, and stressful life events.

SIGNIFICANCE

In this cross-sectional study designed specifically to investigate depression in epilepsy, we showed that general risk factors for depression in other illness and in the general population are also important in patients with epilepsy, with little support for disease-related risk factors.

Depression remission, receipt of problem-solving therapy, and self-care behavior frequency among low-income, predominantly Hispanic diabetes patients

OBJECTIVE

This study explored whether depression remission and problem-solving therapy (PST) receipt are associated with more frequent self-care behaviors via cross-sectional and prospective analyses.

METHOD

We analyzed data from a randomized clinical trial (N=387) that tested collaborative depression care among predominantly Hispanic patients with diabetes in safety-net clinics. Data at 12-month follow-up, measured with the Patient Health Questionnaire-9 and Hopkins Symptom Checklist-20, were used to define depression remission. PST was provided by a bilingual social worker. Multivariate regression analysis was used to examine associations between predictors and frequency change of each self-care behavior (healthy diet, exercise, self-blood glucose monitoring, and foot care between baseline and 12-month (N=281), 18-month (N=249), and 24-month (N=235) follow-up surveys.

RESULTS

Inconsistent relationships were observed depending on the instrument to identify depression remission, type of self-care behaviors, and time when self-care behavior was measured. Significant associations were more likely to be observed in cross-sectional analyses. PST receipt was not associated with self-care behaviors.

CONCLUSIONS

Depression remission or the receipt of PST may not be a reliable antecedent for more frequent self-care behaviors among this group. A few recommendations for studies were offered to enhance existing depression care for diabetes patients.

Major Depression as a Predictor of Poor Long-Term Survival in a Brazilian Stroke Cohort (Study of Stroke Mortality and Morbidity in Adults) EMMA study

BACKGROUND

The influence of poststroke depression on long-term survival is poorly investigated. Thus, we aimed to evaluate the influence of major depression disorder (MDD) on long-term survival in the participants from The Study of Stroke Mortality and Morbidity in Adults (EMMA Study) in São Paulo, Brazil.

METHODS

We prospectively evaluated ischemic and hemorrhagic stroke (HS) cases from the EMMA Study. Baseline and stroke characteristics and cardiovascular risk factors were evaluated according to MDD assessed by the Patient Health Questionnaire, which was applied 30 days after index event and periodically during 1-year follow-up. We performed Kaplan-Meier survival analysis, as well as crude and multiple Cox proportional hazards models.

RESULTS

In this subset of the EMMA Study, we evaluated 164 (85.9%) patients with ischemic stroke and 27 (14.1%) with HS. Among these, overall incidence of MDD was 25.1% during 1 year of follow-up, regardless stroke subtype. The peak rate of major depression postacute event was beyond 1 month. We observed a lower survival rate among individuals who developed poststroke MDD than among those who did not develop this condition after 1 year of follow-up (85.4% versus 96.5%, log rank P = .006). After multiple analysis, we kept a higher risk of all-cause mortality among those who developed MDD compared to participants without MDD (hazard ratio = 4.60, 95% confidence interval = 1.36-15.55, P = .01).

CONCLUSION

Our findings suggest that incident MDD is a potential marker of poor prognosis 1 year after stroke.

Hospitalization risk according to geriatric assessment and laboratory parameters in elderly hematologic cancer patients

BACKGROUND

Utilizing geriatric screening tools for the identification of vulnerable older patients with cancer is important. The aim of this study is to evaluate the hospitalization risk of elderly hematologic cancer patients based on geriatric assessment and laboratory parameters.

MATERIALS AND METHODS

In this cross sectional study 61 patients with hematologic malignancies, age 65 years and older, were assessed at a hematology outpatient clinic. Standard geriatric screening tests; activities of daily living (ADL), instrumental activities of daily living (IADL), Mini Nutritional Assessment (MNA), Mini Mental State Examination (MMSE), timed up and go test (TUG), geriatrics depression scale (GDS) were administered. Demographic and medical data were obtained from patient medical records. The number of hospitalizations in the following six months was then recorded to allow analysis of associations with geriatric assessment tools and laboratory parameters.

RESULTS

The median age of the patients, 37 being males, was 66 years. Positive TUG test and declined ADL was found as significant risk factors for hospitalization (p=0.028 and p=0.015 respectively). Correlations of hospitalization with thrombocytopenia, vitamin B12 and folic acid deficiency were statistically significant (p=0.004, p=0.011 and p=0.05 respectively).

CONCLUSIONS

In this study, geriatric conditions which are usually unrecognized in a regular oncology office visit were identified. Our study indicates TUG and ADL might be use as predictive tests for hospitalization in elderly oncology populations. Also thrombocytopenia, and vitamin B12 and folic acid deficiencies are among the risk factors for hospitalization. The importance of vitamin B12 and folic acid vitamin replacement should not be underestimated in this population.

Effects of comorbid health conditions on healthcare expenditures among people with severe mental illness

BACKGROUND AND AIMS

Little is known about the incremental cost burden associated with treating comorbid health conditions among people with severe mental illness (SMI). This study compares the extent to which each individual medical condition increases healthcare expenditures between people with SMI and people without mental illness.

METHODS

Data were obtained from the 2011 Medical Expenditure Panel Survey (MEPS; N = 17 764). Mental illness and physical health conditions were identified through ICD-9 codes. Guided by the Andersen's behavioral model of health services utilization, generalized linear models were conducted.

RESULTS

Total healthcare expenditures among individuals with SMI were approximately 3.3 times greater than expenditures by individuals without mental illness ($11 399 vs. $3449, respectively). Each additional physical health condition increased the total healthcare expenditure by 17.4% for individuals with SMI compared to the 44.8% increase for individuals without mental illness.

CONCLUSIONS

The cost effect of having additional health conditions on the total healthcare expenditures among individuals with SMI is smaller than those individuals without mental illness. Whether this is due to limited access to healthcare for the medical problems or better coordination between medical and mental health providers, which reduces duplicated medical procedures or visits, requires future investigation.

Depression and risk of hospitalisations and rehospitalisations for ambulatory care-sensitive conditions in Denmark: a population-based cohort study

OBJECTIVE

Hospitalisations for ambulatory care-sensitive conditions (ACSCs), a group of chronic and acute illnesses considered not to require inpatient treatment if timely and appropriate ambulatory care is received, and early rehospitalisations are common and costly. We sought to determine whether individuals with depression are at increased risk of hospitalisations for ACSCs, and rehospitalisation for the same or another ACSC, within 30 days.

DESIGN

National, population-based cohort study.

SETTING

Denmark.

PARTICIPANTS

5,049,353 individuals ≥ 18 years of age between 1 January 2005 and 31 December 2013.

MEASUREMENTS

Depression was ascertained via psychiatrist diagnoses in the Danish Psychiatric Central Register or antidepressant prescription redemption from the Danish National Prescription Registry. Hospitalisations for ACSCs and rehospitalisations within 30 days were identified using the Danish National Patient Register.

RESULTS

Overall, individuals with depression were 2.35 times more likely to be hospitalised for an ACSC (95% CI 2.32 to 2.37) versus those without depression after adjusting for age, sex and calendar period, and 1.45 times more likely after adjusting for socioeconomic factors, comorbidities and primary care utilisation (95% CI 1.43 to 1.46). After adjusting for ACSC-predisposing comorbidity, depression was associated with significantly greater risk of hospitalisations for all chronic (eg, angina, diabetes complications, congestive heart failure exacerbation) and acute ACSCs (eg, pneumonia) compared to those without depression. Compared to those without depression, persons with depression were 1.21 times more likely to be rehospitalised within 30 days for the same ACSC (95% CI 1.18 to 1.24) and 1.19 times more likely to be rehospitalised within 30 days for a different ACSC (95% CI 1.15 to 1.23).

CONCLUSIONS

Individuals with depression are at increased risk of hospitalisations for ACSCs, and once discharged are at elevated risk of rehospitalisations within 30 days for ACSCs.

Valuation of depression co-occurring with a somatic condition: feasibility of the time trade-off task

BACKGROUND

Health state valuations obtained from the general population are used for cost-utility analyses of health-care interventions. Currently, most studies have focused on valuations of somatic conditions, to a much lesser extent of mental states, that is, depression and even less on valuations of depression co-occurring with somatic conditions.

OBJECTIVE

We tested the feasibility of the time trade-off (TTO) task to elicit valuations for depression solitary or co-occurring with a somatic condition. Moreover, we explored person- and state-related factors that may affect valuations.

DESIGN

During semi-structured interviews, 10 individuals (five women, mean age: 36 years) used a TTO task to value vignettes describing mild and severe depression; and mild depression co-occurring with moderate and severe states of cancer, diabetes or heart disease. During valuations, participants were thinking aloud. Feasibility criteria were successful completion and difficulty/concentration (1-10); logical consistency of values; and comprehension of the TTO, based on qualitative analysis of think aloud data. Factors influencing valuations were generated from think aloud data.

RESULTS

Participants reported satisfactory levels of difficulty (mean: 1.9) and concentration (mean: 8.3) and assigned consistent values. Qualitative analysis revealed difficulties with imagining: living with depression for lifetime (n = 4); reaching the age of 80 (n = 6); and living with a somatic condition and mentally healthy (n = 6). Person- and state-related factors, for example perceived susceptibility to depression (n = 4), appeared to affect valuations.

CONCLUSION

Quantitative findings supported feasibility of the valuation protocol, yet qualitative findings indicated that certain task aspects should be readdressed. Factors influencing valuations can be explored to better understand valuations.

The Feasibility of Using Large-Scale Text Mining to Detect Adverse Childhood Experiences in a VA-Treated Population

Free text in electronic health records resists large-scale analysis. Text records facts of interest not found in encoded data, and text mining enables their retrieval and quantification. The U.S. Department of Veterans Affairs (VA) clinical data repository affords an opportunity to apply text-mining methodology to study clinical questions in large populations. To assess the feasibility of text mining, investigation of the relationship between exposure to adverse childhood experiences (ACEs) and recorded diagnoses was conducted among all VA-treated Gulf war veterans, utilizing all progress notes recorded from 2000-2011. Text processing extracted ACE exposures recorded among 44.7 million clinical notes belonging to 243,973 veterans. The relationship of ACE exposure to adult illnesses was analyzed using logistic regression. Bias considerations were assessed. ACE score was strongly associated with suicide attempts and serious mental disorders (ORs = 1.84 to 1.97), and less so with behaviorally mediated and somatic conditions (ORs = 1.02 to 1.36) per unit. Bias adjustments did not remove persistent associations between ACE score and most illnesses. Text mining to detect ACE exposure in a large population was feasible. Analysis of the relationship between ACE score and adult health conditions yielded patterns of association consistent with prior research.

Pain Intensity and Pain Interference in Patients With Lung Cancer: A Pilot Study of Biopsychosocial Predictors

OBJECTIVE

To explore biopsychosocial factors (beliefs, depression, catastrophizing cytokines) in individuals newly diagnosed with lung cancer and no pain to determine their relationship at diagnosis and across time and to determine whether these factors contribute to pain intensity or pain interference with function at pain onset.

MATERIALS AND METHODS

A longitudinal, exploratory, pilot study was implemented in a private medical center and a VA medical center in the southeast. Twelve subjects not experiencing pain related to cancer of the lung or its treatment were recruited. A Karnofsky status of 40% and hemoglobin of 8 g were required. Five questionnaires were completed and 10 mL of blood was drawn at baseline; 4 questionnaires and blood draws were repeated monthly for 5 months. One baseline questionnaire and a pain assessment were added at final. Demographic, clinical, and questionnaire data were summarized; standardized scale scores were calculated.

RESULTS

Biopsychosocial scores that were low at baseline increased from T1-T4 but decreased slightly T5-T6. Individuals with higher pain intensity and higher pain interference at final had higher psychosocial scores at baseline than individuals with lower pain intensity and lower pain interference at final.

CONCLUSIONS

Unrelated to disease stage, metastasis, or treatment, unique levels of biopsychosocial factors are observed in patients newly diagnosed with lung cancer who report higher levels of pain intensity and higher levels of pain interference at the time pain occurs. Replication studies are needed to validate this response pattern and determine the value of repeated individual assessments.

Psychological Symptoms Among Obstetric Fistula Patients Compared to Gynecology Outpatients in Tanzania

BACKGROUND

Obstetric fistula is a childbirth injury prevalent in sub-Saharan Africa that causes uncontrollable leaking of urine and/or feces. Research has documented the social and psychological sequelae of obstetric fistula, including mental health dysfunction and social isolation.

PURPOSE

This cross-sectional study sought to quantify the psychological symptoms and social support in obstetric fistula patients, compared with a patient population of women without obstetric fistula.

METHOD

Participants were gynecology patients (N = 144) at the Kilimanjaro Christian Medical Center in Moshi, Tanzania, recruited from the Fistula Ward (n = 54) as well as gynecology outpatient clinics (n = 90). Measures included previously validated psychometric questionnaires, administered orally by Tanzanian nurses. Outcome variables were compared between obstetric fistula patients and gynecology outpatients, controlling for background demographic variables and multiple comparisons.

RESULTS

Compared to gynecology outpatients, obstetric fistula patients reported significantly higher symptoms of depression, post-traumatic stress disorder, somatic complaints, and maladaptive coping. They also reported significantly lower social support.

CONCLUSION

Obstetric fistula patients present for repair surgery with more severe psychological distress than gynecology outpatients. In order to address these mental health concerns, clinicians should engage obstetric fistula patients with targeted mental health interventions.

Depressive symptom trajectories over a 6-year period following myocardial infarction: predictive function of cognitive appraisal and coping

The association between distinct patterns of depression and coping variables in myocardial infarction (MI) survivors over the long-term is unclear. The study aims to evaluate depressive trajectories and their covariates, including coping and cognitive appraisal, following MI over a period of 6 years. Depressive symptoms were assessed in 200 patients a few days after the first MI, and 1 month, 6 months and 6 years later. Cognitive appraisal and coping were assessed during the first three time points. Three latent depressive trajectories were identified: chronic (high; increasing then decreasing; n = 49), rising (moderate; decreasing then increasing; n = 121) and low (low; decreasing then stabilizing; n = 30). The chronic trajectory was associated with higher negative appraisal and emotion-focused coping. The findings clarify the long-term longitudinal trajectories of post-MI depressive symptoms and their association with coping variables, revealing the unfavorable impact of negative cognition and palliative coping.

Does a college education reduce depressive symptoms in American young adults?

Higher levels of educational attainment are consistently associated with better mental health. Whether this association represents an effect of education on mental health, however, is less clear as omitted variable bias remains a pressing concern with education potentially serving as a proxy for unobserved factors including family background and genetics. To combat this threat and come closer to a causal estimate of the effect of education on depressive symptoms, this study uses data on 231 monozygotic twin pairs from The National Longitudinal Study of Adolescent to Adult Health and employs a twin-pair difference-in-difference design to account for both unobserved shared factors between twin pairs (e.g. home, school, and neighborhood environment throughout childhood) and a number of observed non-shared but theoretically relevant factors (e.g. cognitive ability, personality characteristics, adolescent health). We find an inverse association between possessing a college degree and depressive symptoms in both conventional and difference-in-difference models. Results of this study also highlight the potentially overlooked role of personality characteristics in the education and mental health literature.

Depression and hopelessness in patients with acute leukemia: the psychological impact of an acute and life-threatening disorder

OBJECTIVE

Acute leukemia (AL) is a life-threatening cancer associated with substantial morbidity and mortality, particularly in older adults. Given that there has been little research on the psychological impact of such malignancies with acute onset, we assessed the prevalence and correlates of depression and hopelessness in patients with AL.

METHODS

Three hundred forty-one participants were recruited within 1 month of diagnosis or relapse and completed the Beck Depression Inventory-II (BDI-II), Beck Hopelessness Scale (BHS), Memorial Symptom Assessment Scale, and other psychosocial measures. Multivariate regression analyses identified correlates of depression and hopelessness.

RESULTS

17.8% reported clinically significant depressive symptoms (BDI-II ≥ 15), 40.4% of which were in the moderate-severe range (BDI-II ≥ 20). 8.5% reported significant symptoms of hopelessness (BHS ≥ 8). Depression was associated with greater physical symptom burden (adjusted R(2)  = 48.4%), while hopelessness was associated with older age and lower self-esteem (adjusted R(2)  = 45.4%). Both were associated with poorer spiritual well-being.

CONCLUSIONS

Clinically significant depressive symptoms were common early in the course of AL and related to physical symptom burden. Hopelessness was less common and associated with older age and lower self-esteem. The results suggest that whereas depression in AL may be related to disease burden, the preservation of hope may be linked to individual resilience, life stage, and realistic prognosis.Copyright © 2015 John Wiley & Sons, Ltd.
