Immunoglobulins, cognitive status and duration of illness in alzheimer''s disease

Immunologic changes have been reported in the dementing illnesses of mid and late life. The results of two studies of drug-free males meeting research diagnostic criteria for primary neuronal degeneration of the Alzheimer's type suggest that serum IgG levels decrease with the progression of dementia. Serum IgG levels were inversely correlated with duration of illness and the levels of psychiatric symptomatology. Performance on the mini-mental status examination was positively associated with serum IgG concentrations.     

Personality and patient adherence: Correlates of the five-factor model in renal dialysis

The five-factor taxonomy of personality traits has received increasing attention in the literature regarding personality correlates of health outcomes and behaviors. We examined the association of the five NEO Five-Factor Inventory dimensions to medical regimen adherence in a sample of 72 renal dialysis patients. Results indicated that Conscientiousness (Dimension III) is a five-factor trait significantly associated with adherence to the medication regimen. No other NEO-FFI dimension was significantly associated with patient adherence.     

Recovery of function in cat visual cortex following prolonged deprivation

Summary Evidence that there is a critical period during which response characteristics of neurons in visual cortex of the cat may be influenced has been provided in several studies, which suggest that the period of influence is restricted to the first few months of life. Using a somewhat different experimental procedure, we have obtained evidence that cortical units retain plasticity long after the end of this period has passed. In our procedure prolonged visual deprivation was followed by exposure in a normal visual environment. The animals were maintained throughout the first year of life either in total darkness or in an enclosure illuminated intermittently by a strobe light. Following the period of deprivation, electrophysiologic recordings were taken from some of these animals. The remaining cats were permitted 6–12 months in a normally-illuminated environment prior to recording. Cats of the same age reared from birth in a normally lit environment were also recorded.Cortical neurons in cats deprived of any normal visual experience rarely show orientation selective responses. In animals allowed subsequent normal visual experience about one-half of the units studied exhibited this property. This level of response specificity is intermediate between that of normally-reared and recently-deprived animals. While most cortical units in normally-reared cats exhibit direction selectivity, this property is rarely observed in the recovery cats. A number of unit types which are rarely observed in either normal or totally deprived animals were encountered in cats that had normal exposure following prolonged deprivation. A convergent strabismus was observed, in contrast with the divergent strabismus often shown by cats immediately following prolonged visual deprivation. This shows that ocular alignment as well as cortical unit properties can remain plastic in the adult.Supported by NRC Grant No. A9939 and M.R.C.

Heart-focused anxiety,illness beliefs,and behavioral impairment: Comparing healthy heart-anxious patients with cardiac and surgical inpatients

Psychological features and complaints of persons presenting to medical settings with heart-focused anxiety and noncardiac chest pain are poorly understood. Comparing 20 healthy heart-anxious patients to cardiac and surgical inpatients and nonpatient controls, we found that healthy heart-anxious patients (a) were as afraid of chest pain and heart palpitations as inpatients with heart disease, (b) were as incapacitated by symptoms and using medical services as much as both inpatient groups; and (c) reported higher levels of cardiac disease conviction, heart awareness, and behaviors designed to protect their heart than surgical patients and nonpatients. Compared to all other groups, healthy heart-anxious patients reported more panic and other anxiety disorders, hypochondriacal beliefs, physical symptoms, obsessive-compulsive concerns, and negative affect. Following a hyperventilation test, heart-anxious patients also indicated more distressing symptoms and thoughts, and felt less safe and in control than surgical patients and nonpatients. Results support efforts for a timely recognition, diagnosis, and behavioral treatment of persons with heart-focused anxiety.     

Children''s perceptions of chronic illness: the roles of disease symptoms, cognitive development, and information

This experiment considered the acceptance of chronically illchildren by their peers as a result of the peer's level of cognitivedevelopment, the type of disease, and the amount of informationprovided. The results of multivariate and univariate analysesof variance indicate that (a) children's comprehension of illnessescan be improved significantly with the provision of explanatoryinformation, although preoperational children are less ableto retain specifics, (b) preoperational children as well asuninformed children perceived themselves as significantly morevulnerable to contagion, (c) the more observable illness wasseen as significantly less attractive, and (d) provision ofinformation about the nature of a highly observable illnesstended to decrease rather than increase attraction.     

Behavior Problems in Children With Diabetes: Disentangling Possible Scoring Confounds on the Child Behavior Checklist

Objective: The Child Behavior Checklist (CBCL; T. M. Achenbach,1991), when used to assess the behavior of children with diabetes,may contain confounds because some behavioral items can havea physiologic etiology, and may skew reports of behavioral disturbance. Methods: Two techniques were used to disentangle possible scoringconfounds in the behavioral ratings of children with and withoutdiabetes: (1) the Somatic Complaints scale was deleted, or (2)Diabetes Items, identified a priori with 89% agreement by ninemedical personnel, were deleted. Results: As expected, with traditionally scored protocols, childrenwith diabetes obtained higher Internalizing and Total BehaviorProblem scores than controls. This group difference persistedwhether the Somatic Complaints scale or the Diabetes Items weredeleted. Conclusions: Compared to controls, children with diabetes obtainedmildly elevated scores on six of the eight CBCL scales, regardlessof scoring method, suggesting that their mildly elevated behavioralprofile is not confounded by physiologic symptomatology.     

Minnesota Multiphasic Personality Inventory (MMPI) cluster groups among chronically ill patients: Relationship to illness adjustment and treatment outcome

Cluster analysis of the MMPI has been utilized widely in the chronic low back pain literature to try to identify reliable patient subtypes predictive of treatment outcome. We extended this methodology to patients with heterogeneous chronic medical conditions by replicating prototypic MMPI cluster group profiles and by relating cluster groups to clinical baseline and outcome data. Subjects were two independent samples (n=254 and n=263) of chronically ill patients admitted to an inpatient medicine/psychiatry unit. Using a four-cluster solution, similar cluster profile groups were replicated in both samples. Consistent differences emerged between cluster groups on functional impairment, psychiatric diagnoses, depression, and psychosomatic symptoms. Cluster group membership also predicted changes in functional impairment and depression six months after treatment. Results are discussed in terms of similarities between chronic low back pain and chronic illness and tailoring treatment to different patient types.This research was supported in part by a grant from the Henry J.

Adherence-Facilitating Behaviors of a Multidisciplinary Pediatric Rheumatology Staff

Investigated the behaviors of pediatric rheumatology healthcare providers that were expected to be related to patient orparent adherence. Medical charts of 108 patients ages 1 to 20years diagnosed with Juvenile Rheumatoid Arthritis were examined.The 473 outpatient visits over 15 months yielded a total of2,578 treatment recommendations, but only 1,390 adherence-facilitatingbehaviors by medical staff were documented. Providing informationabout how often to perform the recommendation was the most commonstaff behavior. In contrast, care providers rarely indicatedthat they addressed their patients' concerns and barriers toimplementing the recommendations, or employed behavior modificationstrategies to increase adherence. Implications of these findingsfor development of programs designed to increase treatment adherencein children with chronic diseases requiring time-consuming,intrusive medical regimens are discussed.     

THE EFFECTS OF CHANGES IN AROUSAL LEVEL ON CRITICAL FLICKER FUSION FREQUENCY AND FIGURAL REVERSAL TASKS

The present study was designed to investigate the relationship between intra-and inter-individual differences in arousal level and performance on both critical flicker fusion frequency and figural reversal tasks. Forty male undergraduate Ss were used. Electrical skin conductance was used as the indicant of arousal level. For the intra-individual comparisons white noise was used to increase the Ss’arousal levels. Significant inverted U-shaped relationships were found between both flicker fusion thresholds and rates of figural reversal and skin conductance between individuals. A significant curvilinear relationship was found between rates of figural reversal and level of conductance within individuals. No significant curvilinear relationship was found between flicker fusion thresholds and level of conductance within individuals.
