Recombinant allergens for diagnosis of allergic bronchopulmonary aspergillosis

PURPOSE: The investigation aimed at assessing the prevalence of depression among residents in a nursing home. METHODS: In a rural area of Germany a representative sample was examined by means of the "Brief Assessment Interview" (BAI). RESULTS: 17% had a depressive disorder without dementia, 9% had a mild dementia syndrome and a depressive disorder; a total of 47% suffered from symptoms of dementia without depression. Most of the patients were treated by general practitioners or internists. 11% of the patients with depression were treated with antidepressants, 19% with neuroleptics, 17% with minor tranquillizers, and 17% with hypnotics. Only 20% of the depressive patients had ever been examined by a psychiatrist, 4% underwent an actual psychiatric therapy. CONCLUSION: Elderly patients with depressive disorders living in nursing homes need a more specific psychiatric treatment.

OBJECTIVE: The aim of this study was to assess the frequency and severity of depressive symptoms, to determine the rate of depressive disorder, to explore possible reasons for the development of depressive symptoms and to examine the effects of depression in a group of human immunodeficiency virus (HIV)-positive patients. METHOD: HIV-positive patients attending an outpatient treatment facility were assessed by the research psychologist and completed a number of questionnaires: the Beck Depression Inventory (BDI); the Life Event Inventory (LEI); the Core Bereavement Item (CBI-17) questionnaire; and the Psychosocial Adjustment to illness Scale (PAIS). Patients scoring > or = 14 on the BDI were seen by the psychiatrist for further assessment, and where appropriate, diagnoses were made according to DSM-III-R criteria. RESULTS: One hundred and ninety-two patients participated in the study; 95 scored > or = 14 on the BDI and one-third of these were found to have a depressive disorder. Factors significantly predictive of a BDI score > or = 14 were: an LEI score > 77; a diagnosis of acquired immunodeficiency syndrome (AIDS); being on sickness benefits or a pension; no current relationship; and a past history of depression. Few differences were demonstrated between those with a depressive disorder and those with a BDI score > or = 14 but no diagnosis of depressive disorder. Both groups had high mean PAIS scores indicating significant illness effects in multiple areas of function. CONCLUSIONS: Depressive symptoms are common among patients with HIV infection. Few factors differentiate between patients with a depressive disorder and those whose depressive symptoms do not meet diagnostic criteria. Substantial disability is present in both groups.     

Velogenic Newcastle disease virus in captive wild birds

This study investigated the correlates of change in behavioral disturbance in geropsychiatric inpatients with dementia. It was hypothesized that improvement in specific psychiatric symptoms, such as psychosis and depression, contribute to the improvement of specific behavioral disturbances. All admissions between October 1993 and May 1995 were reviewed to identify those patients admitted to the Houston VA geropsychiatry unit with a diagnosis of dementia; 233 patients were included in the study. Improvement in behavioral disturbance symptoms was associated with decreases in depression, thought disorder, and hostility. However, the relative importance of depressive and psychotic symptoms varied depending upon the type of behavioral disturbance examined. These results may support a focused approach employing therapies specific to the type of behavioral disturbance.     

Memory complaint and memory performance in the depressed elderly.

Compared depressed and nondepressed elderly Ss recruited in the context of a large epidemiological study of health on measures of self-reported memory disturbance and an objective index of memory performance (free recall). Three groups were studied: (a) 26 Ss (mean age 71.56 yrs) meeting Research Diagnostic Criteria (RDC) for major depression, (b) 25 Ss (mean age 72.16 yrs) with high levels of self-reported depressive symptoms who did not meet RDC for major depression, and (c) 26 Ss (mean age 71.81 yrs) with low levels of self-reported depressive symptoms. Ss with high depression symptom levels reported significantly higher levels of memory complaint than did Ss with low symptom levels, but there were no differences in self-reported memory disturbance as a function of depression diagnosis. There were no significant differences between groups on the free-recall measure, either as a function of symptom level or diagnosis. It is argued that symptom severity rather than diagnosis of depression is important in determining impairment in depressed elderly people.

Psychiatric assessments of nursing home residents under OBRA-87: should PASARR be reformed? Pre-Admission Screening and Annual Review

OBJECTIVE: As part of nursing home practice reforms, OBRA-87 mandates formal psychiatric assessments (PASARR) of nursing home residents suspected of having mental disorders, a responsibility it delegates individually to states. We describe the initial year of implementation of the PASARR process in King County, Washington, and characterize the mental disorders and mental health services needs of nursing home residents referred for psychiatric screening. DESIGN: Cross-sectional study. SETTING: The 54 Medicare-certified King County nursing homes (total beds = 7013). PARTICIPANTS: All patients referred for psychiatric evaluation under PASARR (n = 510). MEASUREMENTS: A systematic, multidimensional evaluation including a semistructured psychiatric diagnostic examination, validated measures of cognitive dysfunction, depression, and global psychopathology, functional variables relevant to need for nursing home care, and selected mental health services indicators. RESULTS: Fewer than 10% of all nursing home residents were referred for psychiatric evaluation. A primary mental illness, evenly divided between psychoses and mood disorders, was found in 60% of the sample, and a psychiatric disorder associated with dementia or mental retardation was found in 25%. Six percent had complex neuropsychiatric features defying classification, and 4% had no mental disorder. Other disorders, such as substance abuse, were rare. Cognitive impairment and global psychopathology were prevalent in all diagnostic groups, and depressive symptoms were common even in patients without affective diagnoses. Eighty-eight percent of the sample were appropriately placed, based on their needs for daily care. Fifty-five percent had unmet mental health services needs. CONCLUSIONS: The PASARR referral process detected a group of seriously mentally ill, functionally disabled patients, most of whom required the level of care that nursing homes provide. Depressed and psychiatrically impaired dementia patients were underrepresented in the referral pool as measured against widely accepted prevalence figures for mental disorders in nursing home populations. The PASARR process as currently configured appears to be most efficient in identifying schizophrenic patients, who represent a small minority of nursing home residents, and the skewed sample it generates fails to provide an adequate basis for estimating overall mental health services needed in nursing homes. The PASARR process should be altered to improve referral rates for depressed and behaviorally disturbed dementia patients.     

Identifying patients with depression in the primary care setting: a more efficient method

OBJECTIVE: To determine if there is a core subset of depressive symptoms that could be used to efficiently diagnose depression after administering the 2-item PRIME-MD a screening questionnaire for depression. METHODS: One thousand patients selected randomly and by convenience from 4 primary care clinics were assessed by PRIME-MD and completed a questionnaire measuring the following validation variables: functional status and well-being, disability days, somatic symptoms, depression severity, suicidal thoughts, health care utilization, and the physician-patient relationship. RESULTS: Four symptoms (sleep disturbance, anhedonia, low self-esteem, and decreased appetite) accounted for virtually all the depression symptom-related variance in functional status and well-being, with 8.3% of patients having 2 of these symptoms and 8.2% having 3 or 4 of these symptoms. There was excellent agreement between diagnosis based on core symptoms and major depression (K= 0.77; overall accuracy rate, 94%). There were significant differences (P<.001) among patients with negative depression screen, 0 to 1, 2, and 3 to 4 core symptoms with scores on each of the validation variables getting progressively worse in these 4 groups. A cutoff point of 2 core symptoms identified all but 3 patients with major depression and an additional 5% of the entire sample without major depression who were significantly (P<.05) worse than patients without depression on each of the validation variables. CONCLUSION: A strategy that includes the use of a 2-item depression screener followed by the evaluation of 4 core depressive symptoms is an efficient and effective way of identifying and classifying primary care patients with depression in need of clinical attention.     

Sepsis and endotoxaemia in mice stimulate the expression of interleukin-I and interleukin-6 in the central nervous system

This retrospective chart review examines the impact of selective serotonin reuptake inhibitors on 20 patients with both depression and psychosis complicating dementia of the Alzheimer type (DAT) and other dementias. Fifteen of the 20 patients had moderate to marked improvement in depressive and psychotic symptoms. Eleven of 12 patients with DAT had moderate to marked improvement compared to only four of eight patients with dementia from other causes. The drugs were effective in diminishing or eliminating psychotic symptoms in six patients who had previously not responded to a trial of a neuroleptic. The selective serotonin reuptake inhibitors may have an important role to play in patients with DAT who have coexisting depression and psychosis. These drugs are very well tolerated and may have a place as first-line agents in non-emergent settings where a clinician might otherwise think of instituting a neuroleptic or as a second-line agent when a neuroleptic has proven ineffective.     

The persistence of race and ethnicity in the use of long-term care

We examine the use of nursing homes, formal personal care, informal Activities of Daily Living (ADL) assistance, and no care to identify racial differences in their use. Using the 1987 National Medical Expenditure Survey of both nursing homes and the community, multinominal logistic regressions controlled for predisposing, enabling, and need variables as well as other types of service use. Additional state-level variables make few changes in race/ethnicity parameters, indicating that race/ethnicity are not simply proxies for state-level variables. Older African Americans are less likely to use nursing homes than similar whites, with the lower institutionalization replaced by a higher use of paid home care, informal-only care, and no care. This suggests that formal in-home community care is not fully compensating for the racial differences in nursing home use. Persistent effects of race/ethnicity could be the result of culture, class, and/or discrimination that may impair equitable access to services.     

A review of racial differences in geriatric depression: implications for care and clinical research

How racial differences influence depressed elders' seeking and obtaining treatment for depression is poorly understood. Studies in other medical illnesses show older African Americans use fewer health-care services for heart disease, stroke, and renal dialysis. This article reviews the racial composition of Duke University's Clinical Research Center (CRC) for the Study of Depression in the Elderly. Possible explanations for low participation of African Americans in such programs also are discussed. During most of the first year of the CRC project, minority enrollment varied from 5% to 10%, at least one third the African-American population of the area. Active efforts to improve minority recruitment increased this percentage to 15% by the end of the project's second year. Likely explanations for low minority participation rates include 1) elders may recognize depressive symptoms, but do not seek or cannot obtain medical treatment, and 2) depressive symptoms may be attributed to a crisis of the spirit (so help is sought through prayer and the church), the "slowing down" process of aging, or part of life's burden to be endured. Future attempts at both treatment and clinical research recruitment efforts are needed to address these possibilities.     

Hippocampal sclerosis contributes to dementia in the elderly

OBJECTIVE: To assess the relevance of hippocampal sclerosis (HS) to dementia in the elderly. BACKGROUND: HS is a prominent pathologic finding in some demented elderly, but the anatomic substrate and cognitive profiles of this dementia have not been well established. DESIGN/METHODS: An autopsy series, including dot-immunobinding assay to estimate neocortical synaptic density, of eight patients (three men, five women) with HS on whom extensive antemortem neuropsychological testing was available. RESULTS: Mean age at onset was 72.0 (+/-9.8) (range, 59 to 89) with a mean duration of symptoms of 6.5 (+/-2.9) years. Patients were only mildly impaired with a mean MMSE of 20.9 (+/-4.9) and a mean DRS of 103.1 (+/-12.5) at presentation. Cardiovascular disease was present in 88%, with a mean Hachinski score of 3.4 (+/-2.2). No patient had a history of seizures. Sixty-three percent had depression or depressive symptoms. Neuropsychologically, most patients presented with prominent memory and language deficits and became progressively demented. Neuropathologically, isolated HS was a rare finding; many patients had either very mild or neocortical "plaque only or plaque predominant" Alzheimer's disease (AD) in addition to HS changes. Midfrontal neocortical synaptophysin counts were significantly reduced in all HS patients compared with controls (p = 0.0006). CONCLUSIONS: In the elderly, HS can be a neuropathologic substrate of dementia. Clinically, it can be associated with a course that is difficult to distinguish from AD although cardiac disease and depression are frequent concomitants. Deterioration of cognitive function in these subjects may relate to other pathologic features such as neocortical synapse loss.     

Depression in elders with dementia: implications for home healthcare practice

In addition to severe cognitive decline, depressive symptoms occur in almost 50% of patients with dementia. Depressive symptoms can be treated successfully, thereby reducing clinical manifestations of coexisting dementia and improving quality of life for these patients and their families. Practical assessment, interventions, and referral guidelines are presented for home healthcare nurse generalists whose caseloads include elders with both cognitive decline and depressive symptoms.     

Depression as a risk factor or prodromal feature for dementia? Findings in a population-based sample of Swedish twins.

This study tested whether history of depression is associated with an increased likelihood of dementia, and whether a first depressive episode earlier in life is associated with increased dementia risk, or whether only depressive episodes close in time to dementia onset are related to dementia. Depression information came from national hospital discharge registries, medical history, and medical records. Dementia was diagnosed clinically. In case–control results, individuals with recent registry-identified depression were 3.9 times more likely than those with no registry-identified depression history to have dementia, whereas registry-identified depression earlier in life was not associated with dementia risk. Each 1-year increase in time between depression onset and dementia onset or equivalent age decreased the likelihood of dementia by 8.4%. In co-twin control analyses, twins with prior depression were 3.0 times more likely to have dementia than their nondepressed twin partners, with a similar age of depression gradient. These findings suggest that after partially controlling for genetic influences, late-life depression for many individuals may be a prodrome rather than a risk factor for dementia.

Does sub-lethal exposure to organophosphate pesticide affect capture rates in free-living rodents?

Patients with clinical diagnoses of Alzheimer's disease, vascular dementia, or undifferentiated dementia were rated on standardized measures of depression, cognitive impairment, and functional impairment. Logistic regression was used to evaluate the relationship between functional or cognitive impairment, as well as their interaction, and depressive features in each group. This analysis revealed notable differences by type of dementia. The results imply that the mechanisms underlying depression in Alzheimer's disease may be different from those in vascular and other types of dementia. These results also provide indicators to the clinician for further evaluation of depression in different dementia subtypes.     

Chronic stress and depressive disorders in older adults.

Current and lifetime rates of Diagnostic and Statistical Manual of Mental Disorders-III—Revised (DSM-III—R) disorders were compared in 86 older adults caring for a spouse with a progressive dementia and 86 sociodemographically matched control subjects. Dementia caregivers were significantly more dysphoric than noncare givers. The frequencies of depressive disorders did not differ between groups in the years before care giving, and there were no group differences in first-degree relatives' incidence of psychiatric disorder. During the years they had been providing care, 30% of care givers experienced a depressive disorder (major depression, dysthymia, or depression not otherwise specified) versus 1% of their matched controls in the same time period. Only two care givers who met criteria during care giving had met criteria for a depressive disorder before care giving, and family history was not even weakly related to the identification of at-risk care givers. In contrast to these group differences in depressive disorders, there were no significant differences in other Axis I disorders either before or during care giving. Thus, the chronic strains of care giving appear to be linked to the onset of depressive disorders in older adults with no prior evidence of vulnerability.

Clinical characteristics of unipolar and bipolar depression

INTRODUCTION: In the last decades affective disorders were divided into unipolar and bipolar and this division has been generally accepted. The bipolar type is manifested by mania or by both mania and depression. On the other hand, unipolar affective disorders are manifested only by depression. In numerous investigations authors have noticed that there are very distinctive differences between these two types of depressive disorders such as: course of illness, personality disorders, sex, family history etc. Nevertheless, in practice it is often very difficult to make the right diagnosis. The bipolar type often starts with a few pure depressive episodes and sometimes mania occurs a few years later so only at that point the psychiatrist can make the right diagnosis and treat the patient correctly. MATERIAL AND METHODS: This investigation comprised 50 patients hospitalized at the Psychiatric Clinic in Novi Sad during 1992-1995. The experimental group consisted of 20 patients with a bipolar affective disorder (according to ICD-X), while the control group consisted of 30 patients with clinical diagnosis of unipolar depression (intensive, without psychiatric features). Both groups of patients were weekly evaluated by Hamilton Depression Rating Scale (HDRS), whereas the initial score for all patients had to be higher than 16. RESULTS: Patients suffering from unipolar depression were older than patients with bipolar depression and there were more females in this group. There were no differences in demographic characteristics (level of education, migration, etc.), but the experimental group had a greater genetic loading for affective disorders. Unipolar depressive patients had more agitation and they were more anxious than patients with bipolar depression. DISCUSSION AND CONCLUSION: The fact that unipolar depressive patients were older than bipolar is similar to most of the results gained in this kind of investigation. On the other hand, we did not find statistical differences in the intensity of disorders, and in the literature these results are contraindicating. Numerous investigators report that bipolar depressives had a stronger genetic loading for affective disorders and our study confirms the same. All these results can help us to make the right diagnosis of unipolar and bipolar affective disorders.     

Decision making and depressive symptoms in Black and White multigenerational teen-parent families.

This study investigated correlates of depressive symptoms among 56 (30 Black and 26 White) low-income, coresiding teenage mothers and their mothers (referred to as grandmothers). Racial differences in teenage mothers' and grandmothers' reports of decision making and depressive symptoms and in the association of decision making with depressive symptoms were explored. Racial differences in levels of depressive symptoms emerged for grandmothers but not for teens. There were no significant differences in levels of decision making; however, the relation of decision making to depressive symptoms differed by racial group. Among White families, greater teen participation in decision making was negatively associated with teenage mothers' depressive symptoms. Among Black families, the opposite was found. A similar pattern of effects was observed for grandmothers. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

An evaluation of a family visit education program

OBJECTIVES: This study was designed to examine the impact of the Family Visit Education Program (FVEP) on family members, nursing staff, and nursing home residents with dementia. DESIGN: The study employed a 2 x 3 single-blind, randomized control group design with two study conditions, FVEP or usual care (UC), and three times of measurement, baseline, 3-months, and 6-months. SETTING: The study was conducted in five skilled-care nursing homes that ranged in size from 120 to 300 beds. PARTICIPANTS: Sixty-six residents with dementia and their primary visitor were randomly assigned to FVEP (n = 32) or UC (n = 34). MEASUREMENTS: Residents were assessed for (1) psychosocial functioning, (2) depression, (3) agitated behavior, and (4) degree of positive social interaction. Nursing staff were assessed for changes in the time and methods used to manage problem behaviors. Visitors were assessed for (1) dementia management skills, (2) extent of perceived caregiving hassles, and (3) visit satisfaction. RESULTS: FVEP was effective for reducing residents' problem behaviors and for decreasing their symptoms of depression and irritability. It was also effective for improving the way family members and other visitors communicated with residents, but, with the exception of reducing the use of mechanical restraints, it was not effective in changing nurses' management of residents' behavior problems. CONCLUSIONS: It is possible to educate family members to communicate and interact more effectively with nursing home residents with dementia. This has beneficial effects on residents but not on nursing staff's management of problem behaviors.     

Depressive symptoms and lymphocyte proliferation in older adults.

In an 18-month prospective study, community-dwelling older adults, including both spousal caregivers of dementia patients and noncaregiving controls, were examined. Participants were selected on the basis of the presence or absence of chronic depressive symptoms that exceeded a cutoff score for clinically relevant depressive symptoms on a self-report symptom measure. Compared with nondepressed older adults, those with chronic, mild depressive symptoms had poorer T cell responses to 2 mitogens from baseline to follow-up. Additionally, among individuals with depressive symptoms, older age was associated with the poorest blastogenic response to the mitogens at follow-up. These findings extend the association between depression and immune function to community-dwelling older adults with chronic, mild depressive symptoms.

Untreated anxiety among adult primary care patients in a Health Maintenance Organization

BACKGROUND: Untreated anxiety may be particularly difficult for primary care physicians to recognize and diagnose because there are no reliable demographic or medical profiles for patients with this condition and because these patients present with a high rate of comorbid psychological conditions that complicate selection of treatment. METHOD: A prospective assessment of untreated anxiety symptoms and disorders among primary care patients. RESULTS: Approximately 10% of eligible patients screened in clinic waiting rooms of a mixed-model health maintenance organization reported elevated symptoms and/or disorders of anxiety that were unrecognized and untreated. These patients with untreated anxiety reported significantly worse functioning on both physical and emotional measures than "not anxious" comparison patients; in fact these patients reported reduced functioning levels within ranges that would be expected for patients with chronic physical diseases, such as diabetes and congestive heart failure. The most severe reductions in functioning were reported by untreated patients whose anxiety was mixed with depression symptoms or disorders. CONCLUSION: Primary care physicians may benefit from screening tools and consultations by mental health specialists to assist in recognition and diagnosis of anxiety symptoms and disorders alone and mixed with depression.
