Association between depressive symptoms and mortality in medical inpatients

Hopelessness and Other Depressive Symptoms in Adults 70 Years and Older as Predictors of All-Cause Mortality Within 3 Months After Acute Hospitalization: The Hospital-ADL Study

OBJECTIVE

Depression among older adults predicts mortality after acute hospitalization. Depression is highly heterogeneous in its presentation of symptoms, whereas individual symptoms may differ in predictive value. This study aimed to investigate the prevalence of individual cognitive-affective depressive symptoms during acute hospitalization and investigate the predictive value of both overall and individual cognitive-affective depressive symptoms for mortality between admission up to 3-month postdischarge among older patients.

METHODS

A prospective multicenter cohort study enrolled 401 acutely hospitalized patients 70 years and older (Hospitalization-Associated Disability and impact on daily Life Study). The predictive value of depressive symptoms, assessed using the Geriatric Depression Scale 15, during acute hospitalization on mortality was analyzed with multiple logistic regression.

RESULTS

The analytic sample included 398 patients (M (SD) = 79.6 (6.6) years; 51% men). Results showed that 9.3% of participants died within 3 months, with symptoms of apathy being most frequently reported. The depression total score during hospitalization was associated with increased mortality risk (admission: odds ratio [OR] = 1.2, 95% confidence interval [CI] = 1.2-1.3; discharge: OR = 1.2, 95% CI = 1.2-1.4). Stepwise multiple logistic regression analyses yielded the finding that feelings of hopelessness during acute hospitalization were a strong unique predictor of mortality (admission: OR = 3.6, 95% CI = 1.8-7.4; discharge: OR = 5.7, 95% CI = 2.5-13.1). These associations were robust to adjustment for demographic factors, somatic symptoms, and medical comorbidities.

CONCLUSIONS

Symptoms of apathy were most frequently reported in response to acute hospitalization. However, feelings of hopelessness about their situation were the strongest cognitive-affective predictor of mortality. These results imply that this item is important in identifying patients who are in the last phase of their lives and for whom palliative care may be important.

Trajectories of cognitive-affective depressive symptoms in acutely hospitalized older adults: The hospital-ADL study

OBJECTIVE

To identify trajectories of cognitive-affective depressive symptoms among acutely hospitalized older patients and whether trajectories are related to prognostic baseline factors and three-month outcomes such as functional decline, falls, unplanned readmissions, and mortality.

METHODS

Prospective multicenter cohort of acutely hospitalized patients aged ≥ 70. Depressive trajectories were based on Group Based Trajectory Modeling, using the Geriatric Depression Scale-15. Outcomes were functional decline, falls, unplanned readmission, and mortality within three months post-discharge.

RESULTS

The analytic sample included 398 patients (mean age = 79.6 years; SD = 6.6). Three distinct depressive symptoms trajectories were identified: minimal (63.6%), mild persistent (25.4%), and severe persistent (11.0%). Unadjusted results showed that, compared to the minimal symptoms group, the mild and severe persistent groups showed a significantly higher risk of functional decline (mild: OR = 3.9, p < .001; severe: OR = 3.0, p = .04), falls (mild: OR = 2.0, p = .02; severe: OR = 6.0, p < .001), and mortality (mild: OR = 2.2, p = .05; severe: OR = 3.4, p = .009). Patients with mild or severe persistent symptoms were more malnourished, anxious, and functionally limited and had more medical comorbidities at admission.

CONCLUSION

Nearly 40% of the acutely hospitalized older adults exhibited mild to severe levels of cognitive-affective depressive symptoms. In light of the substantially elevated risk of serious complications and the fact that elevated depressive symptoms was not a transient phenomenon identification of these patients is needed. This further emphasizes the need for acute care hospitals, as a point of engagement with older adults, to develop discharge or screening procedures for managing cognitive-affective depressive symptoms.

Impact of surgical wound dehiscence on health-related quality of life and mental health

OBJECTIVE

To assess the impact of surgical wound dehiscence on health-related quality of life and mental health. Dehiscence of surgical wounds is a serious postoperative complication associated with high morbidity and mortality.

METHOD

Sixty-one adult patients, who had undergone neurological, general, colorectal, orthopaedic, gynaecological, plastic, cardiovascular, urological or neurological surgery in a university hospital in Brazil, were assessed between 30 and 180 days after surgery. Twenty participants who achieved complete wound healing were allocated to the control group and 41 participants who developed surgical wound dehiscence were allocated to the dehiscence group. Patients unable to complete the questionnaires because of cognitive impairment and those who declined to participate or died were excluded from the study. Data were collected using a questionnaire assessing sociodemographic and clinical characteristics of participants; the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36); and the Beck Depression Inventory (BDI).

RESULTS

Surgical wound dehiscences were 0.5-30 cm in length, 0.5-7 cm in depth, and located in the arms, legs or trunk. There were significant between-group differences in mean scores on the physical functioning (p<0.01), role physical (p<0.01), social functioning (p=0.01), and bodily pain (p=0.01) dimensions of the SF-36. Participants with wound dehiscence reported significantly higher BDI scores (more depressive symptoms) than controls (p=0.01).

CONCLUSION

Surgical wound dehiscence had a negative impact on the physical functioning, role physical, social functioning, and bodily pain dimensions of health-related quality of life and on mental health.

Depressive symptoms in patients with acute coronary syndrome

OBJECTIVE

To trace an epidemiological profile, to verify presence of depressive symptoms in patients with previous diagnosis of acute coronary syndrome and to identify factors that contribute to maintenance of depressive symptoms in the sample.

METHODS

A cross-section study carried out at the Cardiology Outpatients Clinics of Universidade Federal de São Paulo. An instrument prepared by the authors was used, which was based on similar studies with patient identification data, questions related to the psychological follow-up, relationship with family members and friends, in addition to use of the Beck Depression Inventory.

METHODS

A cross-section study carried out at the Cardiology Outpatients Clinics of Universidade Federal de São Paulo. An instrument prepared by the authors was used, which was based on similar studies with patient identification data, questions related to the psychological follow-up, relationship with family members and friends, in addition to use of the Beck Depression Inventory.

RESULTS

A total of 200 patients were interviewed, 127 (63.5%) were male. The mean age was 60.19 years with a standard deviation of 9.38, minimum age of 36 years and maximum of 81 years; 164 (82%) denied any follow-up with a psychologist or psychiatrist in the phase after acute coronary syndrome diagnosis and treatment. In the utilization of Beck Depression Inventory, 67 (33.5%) presented scores between 0 and 4, indicating mild depressive symptoms; 72 (36%) had scores between 5 and 9, indicating mild to moderate depressive symptoms, and 61 (30.5%) presented scores greater than 9, which point out moderate to severe depressive symptoms.

CONCLUSION

The evaluation and multiprofessional follow-up can help patients cope with the illness in addition to providing greater compliance to drug therapy and beginning changes in life habits.

Development of psychiatric risk evaluation checklist and routine for nurses in a general hospital: ethnographic qualitative study

CONTEXT AND OBJECTIVE

There is high prevalence of mental and behavioral disorders in general hospitals, thus triggering psychiatric risk situations. This study aimed to develop a psychiatric risk assessment checklist and routine for nurses, the Psychiatric Risk Evaluation Check-List (PRE-CL), as an alternative model for early identification and management of these situations in general hospitals.

DESIGN AND SETTING

Ethnographic qualitative study in a tertiary-level private hospital.

METHOD

Three hundred general-unit nurses participated in the study. Reports were gathered through open groups conducted by a trained nurse, at shift changes for two months. The questions used were: "Would you consider it helpful to discuss daily practice situations with a psychiatrist? Which situations?" The data were qualitatively analyzed through an ethnographic approach.

RESULTS

The nurses considered it useful to discuss daily practice situations relating to mental and behavioral disorders with a psychiatrist. Their reports were used to develop PRE-CL, within the patient overall risk assessment routine for all inpatients within 24 hours after admission and every 48 hours thereafter. Whenever one item was present, the psychosomatic medicine team was notified. They went to the unit, gathered data from the nurses, patient files and, if necessary, attending doctors, and decided on the risk management: guidance, safety measures or mental health consultation.

CONCLUSION

It is possible to develop a model for detecting and intervening in psychiatric and behavioral disorders at general hospitals based on nursing team observations, through a checklist that takes these observations into account and a routine inserted into daily practice.

The association of post-stroke anhedonia with salivary cortisol levels and stroke lesion in hippocampal/parahippocampal region

BACKGROUND

Anhedonia constitutes a coherent construct, with neural correlates and negative clinical impact, independent of depression. However, little is known about the neural correlates of anhedonia in stroke patients. In this study, we investigated the association of post-stroke anhedonia with salivary cortisol levels and stroke location and volume.

PATIENTS AND METHODS

A psychiatrist administered the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition to identify anhedonia in 36 inpatients, without previous depression, consecutively admitted in a neurology clinic in the first month after a first-ever ischemic stroke. Salivary cortisol levels were assessed in the morning, evening, and after a dexamethasone suppression test. We used magnetic resonance imaging and a semi-automated brain morphometry method to assess stroke location, and the MRIcro program according to the Brodmann Map to calculate the lesion volume.

RESULTS

Patients with anhedonia had significantly larger diurnal variation (P-value =0.017) and higher morning levels of salivary cortisol (1,671.9±604.0 ng/dL versus 1,103.9±821.9 ng/dL; P-value =0.022), and greater stroke lesions in the parahippocampal gyrus (Brodmann area 36) compared to those without anhedonia (10.14 voxels; standard deviation ±17.72 versus 0.86 voxels; standard deviation ±4.64; P-value =0.027). The volume of lesion in the parahippocampal gyrus (Brodmann area 36) was associated with diurnal variation of salivary cortisol levels (rho=0.845; P-value =0.034) only in anhedonic patients.

CONCLUSION

Our findings suggest that anhedonia in stroke patients is associated with the volume of stroke lesion in the parahippocampal gyrus and with dysfunction of the hypothalamic-pituitary-adrenal axis.

Contributors to suicidality in rural communities: beyond the effects of depression

BACKGROUND

Rural populations experience a higher suicide rate than urban areas despite their comparable prevalence of depression. This suggests the identification of additional contributors is necessary to improve our understanding of suicide risk in rural regions. Investigating the independent contribution of depression, and the impact of co-existing psychiatric disorders, to suicidal ideation and suicide attempts in a rural community sample may provide clarification of the role of depression in rural suicidality.

METHODS

618 participants in the Australian Rural Mental Health Study completed the Composite International Diagnostic Interview, providing assessment of lifetime suicidal ideation and attempts, affective disorders, anxiety disorders and substance-use disorders. Logistic regression analyses explored the independent contribution of depression and additional diagnoses to suicidality. A receiver operating characteristic (ROC) analysis was performed to illustrate the benefit of assessing secondary psychiatric diagnoses when determining suicide risk.

RESULTS

Diagnostic criteria for lifetime depressive disorder were met by 28% (174) of the sample; 25% (154) had a history of suicidal ideation. Overall, 41% (63) of participants with lifetime suicidal ideation and 34% (16) of participants with a lifetime suicide attempt had no history of depression. When lifetime depression was controlled for, suicidal ideation was predicted by younger age, being currently unmarried, and lifetime anxiety or post-traumatic stress disorder. In addition to depression, suicide attempts were predicted by lifetime anxiety and drug use disorders, as well as younger age; being currently married and employed were significant protective factors. The presence of comorbid depression and PTSD significantly increased the odds of reporting a suicide attempt above either of these conditions independently.

CONCLUSIONS

While depression contributes significantly to suicidal ideation, and is a key risk factor for suicide attempts, other clinical and demographic factors played an important role in this rural sample. Consideration of the contribution of factors such as substance use and anxiety disorders to suicidal ideation and behaviours may improve our ability to identify individuals at risk of suicide. Acknowledging the contribution of these factors to rural suicide may also result in more effective approaches for the identification and treatment of at-risk individuals.

Vascular burden and cognitive functioning in depressed older adults

BACKGROUND

Vascular burden is known to contribute to geriatric depression and cognitive impairment. The objective of our study was to evaluate the relationship between vascular burden and pattern of cognitive impairment in older adults with depression.

METHODS

Ninety-four community-dwelling older adults (mean age = 70.8 years; SD = 7.63) diagnosed with major depression were recruited to participate in the tai chi complementary use study aimed to improve antidepressant response to an antidepressant medication. All participants received comprehensive evaluations of depression, apathy, and vascular risk factors, and completed a battery of cognitive measures of memory, cognitive control, verbal fluency, and attention.

RESULTS

The severity of vascular burden was significantly correlated with depression severity and impaired performance on measures of cognitive control (i.e., inhibition/mental flexibility), and attention, but not memory or verbal fluency. Neither the severity of comorbid apathy nor medical illness burden was related to cognitive impairment.

CONCLUSIONS

Vascular burden in older depressed adults contributes to cognitive impairment, particularly in domains of attention and cognitive control. Our findings suggest that aggressive treatment of vascular risk factors may reduce risk for further cognitive decline in depressed older adults.

Depression, alcohol use disorders and nicotine dependence among patients at a general hospital

OBJECTIVE: To determine prevalence rates and identify patient characteristics associated with depression, alcohol use disorders and nicotine dependence among individuals admitted to a general teaching hospital. METHOD: Using the Hospital Anxiety and Depression Scale and Alcohol Use Disorder Identification Test, we assessed 4,352 consecutive medical and surgical patients admitted over a 13-month period. The patients were also asked to report their daily cigarette smoking habits during the last month. Multiple logistic regression analyses were performed, and odds ratios (ORs) were calculated. RESULTS: The mean age of the sample was 49.3 years, and 56.6% were male. Prevalence rates of depression, alcohol use disorders and nicotine dependence were, respectively, 14%, 9.8% and 16.9%. In the multivariate analysis, depression was associated with previous suicide attempts (OR = 8.7), lower level of education (OR = 3.6), prior use of psychotropic medications (OR = 3.1), cancer (OR = 1.7) and pain (OR = 1.7). Alcohol use disorders were associated with male sex (OR = 6.3), smoking (OR = 3.5), admission for an external cause of injury, such as a traffic accident (OR = 2.4), and previous suicide attempts (OR = 2.3). Nicotine dependence was associated with alcohol use disorders (OR = 3.4), young adulthood (OR = 2.3), widowhood (OR = 2.2) and previous suicide attempts (OR = 1.8). CONCLUSION: This is the largest sample of medical and surgical patients ever surveyed with standardized screening instruments in a general hospital in Brazil. The high prevalence rates of psychiatric disorders and the profiles of the patients evaluated in this study underscore the need to develop methods that are more effective for detecting and managing such disorders. Hospital admission should be considered a major opportunity for the detection of psychiatric disorders and the subsequent implementation of the appropriate specific treatment strategies.

Evaluation of quality of life in adults with chronic health conditions: the role of depressive symptoms

OBJECTIVE: The negative impact of depressive symptoms on quality of life has been the focus of increasing attention, yet this relation remains unstudied in samples from developing countries. The objective of this study was to determine whether the occurrence of depressive symptoms is associated with impaired quality of life and whether this association remains significant after adjustment for some variables. METHOD: A convenience sample was selected and the measures used were the WHOQOL-100, to assess quality of life, the Beck Depression Inventory, to screen for depressive symptoms, and the Economic Classification Criterion - Brazil, to evaluate socioeconomic status. RESULTS: One hundred nineteen healthy adults (community) and 122 adult patients (tertiary hospital) from Brazil were assessed. Depressive symptoms were negatively correlated with all the domains of quality of life, even after statistical control for age, socioeconomic status, and presence of chronic health conditions. Socioeconomic status was positively correlated with the social relationships and environmental domains of quality of life. CONCLUSION: Our findings indicate that depressive symptoms and socioeconomic status are important elements affecting the relationship between chronic health conditions and quality of life in Brazil.

Association of depressed mood and mortality in older adults with and without cognitive impairment in a prospective naturalistic study

OBJECTIVE

The authors examined predictors of mortality in individuals age 50 or older with or without cognitive impairment in a 12-year prospective naturalistic study of subcortical ischemic vascular disease focusing on symptoms of depressed mood, apathy, anhedonia, or anergia.

METHOD

A total of 498 participants were recruited from the community and from memory clinics into a multicenter longitudinal study of subcortical ischemic vascular disease. For baseline cognitive status, 36% of participants were assessed as cognitively intact, 31% as cognitively impaired, and 33% as demented. All participants underwent a research protocol MRI, and 41% were classified as having subcortical lacunes. Depressed mood, anhedonia, anergia, and apathy were assessed at baseline using a structured behavioral assessment. Cox regression models were used to investigate the associations between neuropsychiatric symptoms and mortality, controlling for age, gender, race, education level, cognitive status, presence of vascular lacunes, and vascular risk factors.

RESULTS

Of 498 participants, 175 (35%) died over the follow-up period, with a median survival time of 5.6 years. In the multivariate analyses, cognitive impairment, age, male gender, depressed mood, and the presence of lacunes predicted higher mortality. Participants with both lacunes and depressed mood had the shortest survival among all cognitive groups. The mortality hazard ratio for participants with depressed mood was 2.2 (95% CI=1.5-3.2) after adjustment for cognitive status, age, gender, education level, race, lacunes, and all vascular conditions.

CONCLUSIONS

These findings suggest the importance of detecting depressed mood in individuals with cerebrovascular disease and of developing more aggressive treatment and preventive interventions for this vulnerable population.

Association of anhedonia with recurrent major adverse cardiac events and mortality 1 year after acute coronary syndrome

CONTEXT

Depression consistently predicts recurrent events and mortality in patients with acute coronary syndrome (ACS), but it has 2 core diagnostic criteria with distinct biological correlates-depressed mood and anhedonia (loss of pleasure or interest).

OBJECTIVE

To determine if depressed mood and/or anhedonia predict 1-year medical outcomes for patients with ACS.

DESIGN

Observational cohort study of post-ACS patients hospitalized between May 2003 and June 2005. Within 1 week of admission, patients underwent a structured psychiatric interview assessing clinically impairing depressed mood, anhedonia, and major depressive episode (MDE). Also assessed were the Global Registry of Acute Coronary Events risk score, Charlson comorbidity index, left ventricular ejection fraction, antidepressant use, and depressive symptom severity using the Beck Depression Inventory.

SETTING

Cardiac units of 3 university hospitals in New York and Connecticut.

PARTICIPANTS

Consecutive sample of 453 patients with ACS (age, 25-93 years; 42% women).

MAIN OUTCOMES MEASURES

All-cause mortality (ACM) and documented major adverse cardiac events (MACEs)-myocardial infarction, hospitalization for unstable angina, or urgent/emergency coronary revascularization)-actively surveyed for 1 year after admission.

RESULTS

There were 67 events (16 deaths and 51 MACEs; 14.8%): 108 (24%) and 77 (17%) patients had anhedonia and depressed mood, respectively. Controlling for sex, age, and medical covariates, anhedonia (adjusted hazard ratio, 1.58; 95% confidence interval, 1.16-2.14; P < .01) was a significant predictor of combined MACE and ACM, but depressed mood was not. Anhedonia continued to significantly predict outcomes (P < .05) when additionally controlling for MDE diagnosis or depressive symptom severity. Findings were confirmed using depressed mood and anhedonia subscores from the Beck Depression Inventory in place of clinician interview ratings.

CONCLUSIONS

Anhedonia identifies risk of MACE and ACM beyond that of established medical prognostic indicators, including MDE and depressive symptom severity. Correlates of anhedonia may add to the understanding of the link between depression and heart disease.

Which factors predict the persistence of DSM-IV depression, anxiety, and somatoform disorders in the medically ill three months post hospital discharge?

OBJECTIVE

This study sought to assess the persistence of DSM-IV depression, anxiety, and somatoform disorders in a sample of 206 medical patients 3 months after hospital discharge and to examine which baseline factors predicted the persistence of disorder.

METHODS

Patients were interviewed using the Monash Interview for Liaison Psychiatry (a structured psychiatric interview for the medically ill) during admission and again at 3 months post discharge. Scales completed during admission elicited sociodemographic data, psychiatric history, mental and physical functioning, illness behavior, coping modes, and number of close relationships. Best-subset logistic regression was employed to find the best combination of these potential predictors of the persistence of psychiatric disorder.

RESULTS

Persistence of anxiety disorders [n=43; 50.6%; 95% CI=39.5-61.6], depression (n=55; 44.4%; 95% CI=35.4-53.5), and somatoform disorders (n=35; 42.2%; 95% CI=31.3-53.0) was moderately high, with no statistically significant difference in the rate of persistence of the three groups of disorder. Family psychiatric history, education, and poorer physical and mental functioning during hospitalization predicted persistence of depression. Poorer mental functioning, less denial, and greater number of close relationships predicted persistence of anxiety disorders. Higher levels of education, use of acceptance-resignation as a coping mechanism, and greater hypochondriasis predicted persistence of somatoform disorders.

CONCLUSION

The belief that psychiatric disorders in hospitalized medically ill patients spontaneously remit after discharge is false. A substantial proportion persist for at least 3 months. Early detection and treatment is possible and warranted. Features of the illness (poorer physical and mental health) and personal and social factors identifiable at hospital admission identify patients at risk for persistence.

Anhedonia as predictor of clinical events after acute coronary syndromes: a 3-year prospective study

BACKGROUND

Depression after acute coronary syndromes (ACS) is an important risk factor for further coronary events; but the influence of anhedonia, the decreased capacity to experience pleasure, has received little attention. The aim of the study was to investigate the effects of anhedonia on prognosis at 3-year follow-up in patients hospitalized for ACS.

METHOD

Consecutively admitted ACS patients (n = 291) completed the Chapman Physical Anhedonia Scale (PAS) and the Hospital Anxiety and Depression Scale depression subscale (HAD-D) at baseline (1-4 days after their admission). Two definitions of anhedonia were taken into account: dimensional definition using PAS score as well as categorical definition using several cutoff scores (hedonics: PAS less than 23 or 29; anhedonics: PAS equal to or greater than 23 or 29). Patients were followed during 3 years for adverse clinical events divided into severe cardiac events (mortality or myocardial infarction [MI]) and clinical events (mortality, MI, recurrence of ACS, hospital readmission, and onset or deterioration of heart failure).

RESULTS

At follow-up, there were 176 clinical events (36 deaths, 8 MIs, 58 ACS, 55 hospital readmissions, 19 heart failures). Dimensional anhedonia and depression were associated with poor prognosis, but anhedonia was the only predictor of severe cardiac events and clinical events after adjusting for demographic and clinical variables. Contrary to depression, categorical anhedonia (PAS >23) was an independent and significant predictor of severe cardiac events after adjusting for clinical variables. The incidence of death/MI in hedonics vs anhedonics was 11.1% vs 22.1% (hazard ratio = 2.18; 95% confidence interval, 1.11-4.26).

CONCLUSIONS

Dimensional and categorical anhedonias predicted independently severe cardiac events and clinical events after ACS.

Sintomas depressivos no câncer de mama: Inventário de Depressão de Beck - Short Form

OBJETIVOS: Verificar a prevalência de sintomas depressivos em mulheres com câncer de mama e identificar os fatores de risco associados à sua ocorrência. MÉTODOS: Foi realizado um estudo transversal, em que foram entrevistadas 71 mulheres com câncer de mama. Foram empregados dois instrumentos: um questionário para verificar os dados sociodemográficos e clínicos e o Inventário de Depressão de Beck - Short Form (BDI-SF), para avaliação dos sintomas depressivos. Para análise dos dados, utilizaram-se medidas descritivas e o teste de qui-quadrado, que avaliou a associação entre variáveis sociodemográficas e clínicas e os sintomas depressivos. O nível de significância considerado foi de 5%. RESULTADOS: A prevalência de sintomas depressivos foi de 29,6%. Os fatores associados à presença desses sintomas foram o tratamento quimioterápico (p = 0,021), presença de dor (p = 0,018) e limitação do movimento do membro superior (p = 0,010) e pior percepção da saúde (p = 0,018). CONCLUSÃO: Sintomas depressivos são frequentes no câncer de mama, assim a saúde mental das mulheres com esse tipo de câncer deve ser investigada e tratada quando necessário, reduzindo o impacto desses sintomas na vida da mulher.

Diagnosticando depressão em pacientes internados com doenças hematológicas: prevalência e sintomas associados

INTRODUÇÃO: Não encontramos estudos avaliando o diagnóstico e a prevalência de depressão em pacientes hematológicos aqui no Brasil. OBJETIVO: Verificar a prevalência dos sintomas depressivos e quais deles mais se associam à depressão em pacientes internados com doenças hematológicas. MÉTODOS: Num estudo transversal, 104 pacientes consecutivamente internados nos leitos da hematologia do Hospital Universitário da Universidade Federal de Santa Catarina (HU/UFSC) foram avaliados. Foram preenchidos questionários de variáveis sociodemográficas e de história psiquiátrica. O índice Charlson de co-morbidade (IC) foi usado para medir gravidade física. Foi aplicado, também, o inventário Beck de depressão (BDI). Aqueles que tiveram pontuação acima de 9 na soma dos 13 primeiros itens do BDI (BDI-13) foram considerados deprimidos. Também foi verificada a freqüência caso fosse utilizada a escala completa com 21 itens (BDI-21), com ponto de corte 16/17. RESULTADOS: As prevalências foram: BDI-13 = 25% e BDI-21 = 32,7%. Após controle para fatores de confusão, os sintomas que permaneceram no modelo da regressão logística, indicando que melhor detectavam os deprimidos, foram sensação de fracasso, anedonia, culpa e fadiga. CONCLUSÃO: Cerca de um quarto a um terço dos pacientes internados com doenças hematológicas tinham sintomas depressivos significativos, e os sintomas que melhor os discriminaram foram sensação de fracasso, anedonia, culpa e fadiga.

Diagnosticando e tratando depressão no paciente com doença clínica

Diagnosticar depressão em um doente clínico é uma tarefa difícil por vários motivos. Muito embora tristeza e humor depressivo possam indicar síndrome depressiva subjacente, eles também podem fazer parte da adaptação normal a uma doença que ameace a vida. Os sintomas somáticos e vegetativos incluídos nos critérios diagnósticos das classificações atuais não são específicos e podem de fato ser atribuíveis à hospitalização, aos tratamentos ou à própria doença clínica. Tratar a depressão no paciente clínico é também difícil devido à preocupação com a interação de drogas, assim como questões de eficácia e segurança nesse grupo. Nesta conferência clínica os autores discutem questões como que diagnósticos podem ser feitos em pacientes clínicos com sintomas depressivos; prevalência de depressão em diferentes ambientes; mecanismos de co-morbidade (fatores fisiológicos e comportamentais) que relacionam a depressão às doenças clínicas e o manuseio da depressão nesse grupo.

Sleep Disturbance Symptoms in Patients With Heart Failure

Sleep disturbances have a major impact on physical functioning, emotional well-being, and quality of life, but are not well described in patients with heart failure (HF). Eighty-four HF patients completed a sleep survey and provided demographic and clinical data. Seventy percent of the patients were male with a mean age of 54 years and a mean left ventricular ejection fraction of 22%. Forty-seven patients (56%) reported trouble sleeping and one-third used sleeping medication. The most frequently reported problems were inability to sleep flat (51%), restless sleep (44%), trouble falling asleep (40%), and awakening early (39%). Using logistic regression, physiological variables were tested as predictors of sleep disturbance. Severity of HF, age, gender, etiology, obesity, smoking, and use of beta-blockers were not predictors of sleep disturbance. HF patients experience significant sleep disturbances, which are not predicted by severity of symptoms or clinical status. Problems with sleep are an important component of a clinical assessment in this vulnerable population.

Mortality in Alzheimer's disease

OBJECTIVE

This study examines the relevance of variables suspected to influence mortality in Alzheimer's disease (AD).

METHODS

172 subjects with AD recruited through a family study were followed up for a mean of 4.7 +/- 2.6 years. Their survival was compared with that of matched control subjects using Kaplan-Meier and log-rank statistics. Variables determining mortality were examined with the Cox proportional hazards model.

RESULTS

Survival in subjects with AD depended on age, the severity of cognitive decline and on the incidence of hospitalisation. Gender, the duration of the illness, the velocity of cognitive decline, the allele E4 of the apolipoprotein E genotype and the presence of other lifetime psychiatric diagnoses did not influence mortality.

CONCLUSION

Mortality in AD depended mainly on the subjects' age and the severity of the disorder.

The impact of psychiatric comorbidity on length of stay of medical inpatients

The aim of the study was to determine the impact of psychiatric comorbidity (PC) on length of hospital stay (LOS) of medical inpatients. A prospective cohort study was conducted. A series of 317 medical inpatients consecutively admitted to the general medical wards of a University Hospital composed the sample, after excluding those who refused or who could not be evaluated due to their physical illnesses or treatments (n=78). Data on demographic and medical variables were collected. A psychiatrist categorized subjects into two cohorts (with and without PC), according to DSM-IV, using the Schedule for Affective Disorders and Schizophrenia, except in patients cognitively impaired who were diagnosed by clinical interview. Mortality and length of stay during the index hospitalization were recorded. At admission, 156 (49%) inpatients had a current psychiatric comorbidity. After controlling for confounders (age and physical severity), in the multivariate analysis of covariance, the patients with cognitive impairment had a significantly prolonged LOS (F=17.8; P<.01) compared with those without cognitive impairment. No difference existed in LOS for the patients with depressive disorders (F=0.36; P=.55), Anxiety disorders (F=1.48; P=.22) or Substance related disorders (F=1.05; P=.30). These results suggest an independent effect of cognitive impairment increasing LOS of medical inpatients.

Depression as a prognostic factor for breast cancer mortality

It is unclear if depression or depressive symptoms have an effect on mortality in breast cancer patients. In this population-based, nationwide, retrospective cohort study in Denmark, depression was defined as affective or anxiety disorders that necessitated psychiatric hospital admission. All the affective and anxiety disorders were divided and categorized into five ordinal diagnostic groups. Early-stage (N=10382) and late-stage (N=10211) breast cancer patients were analyzed separately with Cox's regression adjusted for well-documented somatic prognostic variables. The authors used survival analysis of data from three central registers and found that breast cancer patients with depression had a modestly but significantly higher risk of mortality depending on stage of breast cancer and time of depression. The same result was found after censoring unnatural causes of death such as accident, suicide, or homicide.
