The contribution of striatal (caudate nucleus-putamen) dopaminergic deficiency to the severity of motor signs is well established in Parkinson's disease (PD), while its role in the occurrence of cognitive and mood changes remains unresolved. We therefore measured in 27 non-demented PD patients and 10 age-matched controls striatal uptake of [18F]-6-fluoro-L-Dopa (F-Dopa) with PET, and mood (Beck depression), memory (Grober-Buschke), frontal executive functions (verbal fluency and Wisconsin card sorting), and attentional processing of sensory stimuli (N2-P3 auditory event-related potentials--ERPs). Locomotor disability of patients was assessed by Hoehn and Yahr score and Unified Parkinson's Disease Rating Scale (UPDRS). ANOVA showed that memory, but neither frontal lobe functions nor ERPs, was significantly altered in PD patients, whereas indices of depression were found only in advanced PD. The F-Dopa rate constant Ki was significantly reduced in the striatum, more in putamen than caudate nucleus, and inversely correlated with disease duration. A significant inverse correlation was found between both putamen and caudate nucleus Ki and Hoehn and Yahr score, and between putamen--but not caudate nucleus Ki --and UPDRS motor score. Principal components analysis (PCA) of PD patients Ki values and mood, cognitive and ERP parameters gave a three-factor solution. Variables contributing to factor 1 were memory score and N2-P3 ERP latencies, those to factor 2 were striatal Ki values, and those to factor 3 frontal executive performances. Depression did not segregate with any variable. Our findings suggest that unlike locomotor disability, cognitive abilities and mood state of non-demented PD patients are for the most part unrelated to striatal dopaminergic depletion and may result from dysfunction of extra-striatal dopaminergic or from non-dopaminergic systems.

Changes in the time courses of serum levels of interleukin-6 (IL6) and the soluble form of CD25 (sCD25) were evaluated in 48 burned patients (31 had sepsis, 21 died). Differences among groups along the time were assessed with ANOVA. The Pearson's r correlation coefficient was used to relate quantitative variables. ROC curves were constructed to analyse the prognostic value of IL6 and sCD25. The values of IL6 and sCD25 were related to treatment outcome and time post-burn. In general, two patterns emerged: In non-survivors, there was a depression of sCD25 with time, and an increase in IL6 levels previous to death, whereas survivors had the opposite pattern. On admission, patients with higher levels of sCD25 had a bad prognosis.

The symptom dimensions of childhood-onset schizophrenia (COS) are described by focussing on the clinical features of 44 patients at onset of illness during the first episode and at follow-up investigation 42 years after onset. All subjects were re-diagnosed according to DSM IV. The symptomatology was evaluated with the Positive and Negative Symptom Scale (PANSS) at onset and at follow-up. Two principal component factor analyses with varimax-rotation were applied to the complete items set of the PANSS. The frequencies of positive, negative, and global symptoms were compared longitudinally in an ANOVA-repeated measures design. The factor analysis revealed 5 orthogonal symptom dimensions (factors) at onset of psychosis: Cognition, social withdrawal, antisocial behaviour, excitement, and reality distortion. At follow-up a five-factor solution was found, too, but different dimensions emerged: a positive, negative, excitement, cognitive, and anxiety/depression component which fits to the 5-factor model of White et al. (1997). The first psychotic episode of EOS is accompanied with more unspecific symptoms such as social withdrawal and antisocial behavior. In the later stages of (COS) the structure of symptom dimensions changes to that known from adult-onset schizophrenia (AOS). The results indicate that COS and AOS are comparable nosological entities and that more than 3 dimensions are required to describe the relevant clinical symptom structure. Positive and global symptoms decreased significantly during the course of illness. The frequencies of negative symptoms did not change which demonstrates their disabling impact.

As many as 80% of breast cancer patients report significant distress during initial treatment, yet there is little in the way of systematic psychotherapeutic interventions for women coping with the stress of a recent diagnosis of breast cancer. The literature on psychotherapeutic treatment of cancer patients provides uniform evidence for an improvement in mood, coping and adjustment as a result of group therapy. The present study examined the feasibility of implementing a manualized treatment, supportive-expressive group psychotherapy, in busy oncology practices across the US. This intervention was applied to women with primary breast cancer in a manner which tests not only the efficacy of the approach but also its accessibility to group therapists not previously experienced in its use. One hundred and eleven breast cancer patients within 1 year of diagnosis were recruited from ten geographically diverse sites of the National Cancer Institute's Community Clinical Oncology Program (CCOP) and two academic medical centers. Two therapists from each site were trained in supportive-expressive group psychotherapy. Training consisted of participation in a workshop, reading a treatment manual, and viewing explanatory videotapes. Each patient participated in a supportive-expressive group that met for 12 weekly sessions lasting 90 min. Assessment of mood disturbance was made at entry, 3, 6, and 12 months. Results indicated a significant 40% decrease in the Total Mood Disturbance (TMD) scores of the Profile of Mood States (POMS) (ANOVA F [2,174]=3.98, p<0.05). The total symptom score of the Hospital Anxiety and Depression Scale (HADS) was likewise significantly reduced over the 6-month period (F [2, 174]=5.2, p<0.01). Similarly, the total score of the Impact of Event Scale (IES) was significantly reduced (F [2,174]=4.0, p<0.05). There was substantial uniformity of treatment effect across sites. Outcome was independent of stage of disease (I vs. II). We conclude that this treatment program can be effectively implemented in a community setting and results in reduced distress among breast cancer patients.

This study examines the impact of family conflict and socioemotional support among caregivers who institutionize their relatives. Fifty-two wives, forty-three husbands, and sixty-seven daughters were interviewed before and after the placement of a cognitively impaired relative. A repeated measures ANOVA was performed to examine differences in reports of family conflict and socioemotional support among caregivers. Husbands reported greater increases in family conflict than wives or daughters during the institutionization process. Conversely, wives and daughters indicated higher levels of socioemotional support than husbands. Hierarchical regression equations were then calculated to assess the independent contributions of family conflict and socioemotional support to postplacement adaptation. Decreases in socioemotional support during institutionalization significantly predicted postplacement anger among husbands and increases in family conflict significantly predicted postplacement depression among wives. Overall, family conflict and socioemotional support have important implications among caregivers who institutionalize their relatives.

The present study was designed to evaluate the nature of the differences between psychopathy and depression. Based on previously articulated theoretical models, we hypothesized an inverse relationship between the two clinical constructs. Archival data were retrieved from 231 outpatient clients who had completed measures of depression and psychopathy. Correlational analyses and ANOVA's based on extreme groups supported the hypothesis. Implications for assessment, treatment, and research methodology are discussed.

The purpose of this study was to evaluate effects of wearing complete dentures on swallowing in the elderly. Sixteen nondysphagic edentulous volunteers (mean age: 75.0 yrs) were studied in terms of surface electromyography of the anterior belly of digastrics and masseter muscles, tongue pressure toward the hard palate, and the laryngeal movement. The subjects swallowed 2 ml water under four conditions, with upper and lower dentures, without lower denture, without upper denture, and without upper and lower dentures. Dipper-type of swallowing was prescribed. A repeated-measures ANOVA was used for statistical analysis. Total swallowing duration and the latent period until laryngeal elevation were significantly prolonged without upper or lower denture, and without both dentures (p < 0.05). They were significantly shorter without lower denture than those without upper denture, and without both dentures (p < 0.05). Duration of the preparatory stage was significantly prolonged without upper denture, and without both dentures comparing with the others (p < 0.05). Duration of the oral stage was significantly prolonged without upper denture, and without both dentures comparing with the duration with both dentures (p < 0.05). There were no changes in the pharyngeal stage with or without dentures. The prolongation of total swallowing duration was due to the prolongation of the preparatory and oral stages. The prolongation of swallowing would affect the oral-pharyngeal coordination of swallowing, and exacerbate the depression of swallowing functions with aging. These results suggested that wearing complete dentures contributes to maintain physiological procedure of swallowing in the elderly.

The purpose of this study was to compare patient and proxy (physician and nurse) assessments of symptoms in advanced cancer patients. The sample consisted of 49 patients with advanced cancer admitted to an acute palliative care unit. Three independent assessments were completed for each patient on two occasions within 11 days of admission. On each occasion, symptoms were rated independently by the patient and two proxies (treating physician and nurse), using the Edmonton Symptom Assessment System (ESAS). The ESAS is a nine-item visual analogue scale (VAS) for assessing pain, activity, nausea, depression, anxiety, drowsiness, appetite, well-being and shortness of breath. Symptom ratings were compared using a repeated-measures ANOVA procedure and correlations. Average physician ratings were generally lower than average patient ratings for both occasions. Average nurse ratings agreed more closely with patient ratings, with a trend towards lower ratings on occasion 1 and higher ratings on occasion 2. There was a significant rater (person rating the effects) effect (P < 0.01) for three of the nine symptoms: physicians rated drowsiness, shortness of breath and pain significantly lower than patients. For drowsiness and shortness of breath, these differences were clinically relevant, representing a difference of more than 12 mm on a 100-mm VAS. The accuracy of assessments amongst those rating the symptoms did not improve over time. Proxy assessments of symptom intensity, particularly by physicians, were significantly lower than patient assessments for three of the nine symptoms. Further research regarding the reliability of patient and proxy assessments is needed to assess and manage symptoms in advanced cancer effectively.

To investigate single and combined effects of daily dietary supplementation with 50 mg of vitamin B6 and 200 mg magnesium (as MgO) for one cycle for the relief of mild premenstrual symptoms, a randomized, double-blind, placebo-controlled, crossover design was used. Forty-four women with an average age of 32 years took part in the study. Each woman was randomly assigned, according to a Latin square design, to take consecutively all four of the following treatments daily for one menstrual cycle: (1) 200 mg Mg, (2) 50 mg vitamin B6, (3) 200 mg Mg + 50 mg vitamin B6 and (4) placebo. Throughout the study, each volunteer kept a daily record of symptoms using a 5-point ordinal scale in a menstrual diary of 30 symptoms. Symptoms were grouped into six categories: anxiety, craving, depression, hydration, other, and total. Urinary magnesium output for 24 hours was estimated using the Mg/creatinine concentration ratio. ANOVA showed no overall difference between individual treatments, but predefined treatment comparisons using factorial contrasts in ANOVA showed a significant effect of 200 mg/day Mg + 50 mg/day vitamin B6 on reducing anxiety-related premenstrual symptoms (nervous tension, mood swings, irritability, or anxiety) (p = 0.040). Urinary Mg output was not affected by treatment. A small synergistic effect of a daily dietary supplementation with a combination of Mg + vitamin B6 in the reduction of mild premenstrual anxiety-related symptoms was demonstrated during treatment of 44 women for one menstrual cycle. In view of the modest effect found, further studies are needed before making general recommendations for the treatment of premenstrual symptoms. The study indicated that absorption from MgO was poor and daily supplementation for longer than 1 month is necessary for tissue repletion.

In a placebo-controlled, randomized, modified double-blind study we investigated the effects of body needle acupuncture (n = 10) in 43 patients with minor depression (ICD 10 F32.0, F32.1) and 13 patients with generalized anxiety disorders (ICD10 F41.1). The severity of the disease was assessed by the Clinical Global Impression Scale (CGI). Treatment response was defined as a significant improvement in CGI. An intent-to-treat analysis was performed to compare treatment responses between verum- and placebo acupuncture. After completing an total of 10 acupuncture sessions the verum acupuncture group (n = 28) showed a significantly larger clinical improvement compared to the placebo group (Mann-Whitney test, p < 0.05). There were significantly more responders in the verum-compared to the placebo group (60.7% vs. 21.4%; chi-square test, p < 0.01). In contrast, no differences in the response rates were evident just after 5 acupuncture sessions. A multivariate analysis with the independent factor acupuncture (verum vs. placebo) and the results of the results of the additional rating scales (total score of HAMA, HAMD, Bf-S, BL) as dependent variables (ANOVA, 1:54 D.F.) revealed a clear trend towards lower HAMA scores in the verum group after completing 10 acupunctures (F3.29, p = 0.075). This corresponds well to the high response rate of 85.7% in patients with generalized anxiety disorders, in whom verum acupuncture was applied. Our results indicate that needle acupuncture (Du.20, Ex.6, He.7, Pe.6, Bl.62) leads to a significant clinical improvement as well as to a remarkable reduction in anxiety symptoms in patients with minor depression or with generalized anxiety disorders. The total sum of acupuncture sessions and the specific location of acupuncture needle insertions might be important factors for bringing about therapeutic success.
