The objective was to identify predictors of cognitive decline in patients with hypoxaemic COPD on continuous oxygen therapy. Eighty-four consecutive ambulatory hypoxaemic COPD patients in stable clinical conditions were prospectively studied over the course of 2 yr. Baseline multidimensional assessment included respiratory function tests, blood gas analysis, Mini Mental Status (MMS) test, Geriatric Depression Scale (GDS), Activities of Daily Living (ADLs) and Charlson's index of comorbidity. Reassessments were made 1 yr and 2 yr thereafter. Sequential changes in MMS, GDS and ADLs were assessed by Friedman's ANOVA by rank test. Forty patients completed the study (group A), while 44 died or were lost to follow-up (group B). Group B was characterized by more severe respiratory function impairment and worse performances on ADLs and GDS. In group A, MMS deteriorated from baseline to the 1 yr and 2 yr reassessments (27 +/- 2.9 vs. 25.8 +/- 4.1 and 25.4 +/- 4, P < 0.005), whereas GDS and ADLs did not change significantly; the 23 patients experiencing a decline of MMS had baseline lower percentage predicted FVC (52.3 +/- 17.1 vs. 66.9 +/- 13.4, P < 0.03) and FEV1 (27.2 +/- 8.6 vs. 44 +/- 26.8, P < 0.02) values and better affective status (GDS score: 11.9 +/- 7.7 vs. 16.5 +/- 5.6, P < 0.04). Two-year changes in MMS and in GDS scores were inversely correlated (Spearman's p = -0.32, P = 0.04). Cognitive decline is faster in the presence of severe bronchial obstruction and parallels the worsening of the affective status in COPD patients on oxygen therapy. The onset of depression rather than baseline depressive symptoms seems to be a risk factor for cognitive decline.

The purpose of this study was to examine the relationship between psychosocial adjustment of the burned child and characteristics of the child's family. It hypothesized that parents who perceived their children without major behavioural problems would possess supportive family values and would, themselves, be better adjusted psychologically than those parents who perceived their children as possessing multiple behavioural problems. A stratified random sampling technique was used to select 35 (29 boys, 6 girls) paediatric burn survivors, ages 9 to 18, 1-5 years post-burn, with burn sizes ranging from 3 to 92% burn. Subjects' parents were administered the Child Behaviour Checklist (CBCL), the Family Environment Scale (FES), the Impact of Events Scale (IES), and the Beck Depression Inventory (BDI). The subjects were divided into two groups on the basis of the total problem CBCL scores. i.e. troubled (T > or = 60) or untroubled (T<60). One-way ANOVA tests revealed no significant differences between the two groups in the way parents reacted to trauma (IES) and parental depression (BDI). Significant differences (p<0.01) were revealed between the two groups on FES subscales. The parents of the untroubled group scored higher on 'Cohesion' and 'Organization' and lower on 'Conflict'. These parents also scored higher (p< or =0.05) on 'Achievement Orientation'. The results indicate that work with the family to promote cohesion. to decrease conflict, to enhance stability and to promote expectation of positive achievement must he a part of the rehabilitation of the burned child.

To evaluate the enhancement of mivacurium-induced neuromuscular block by potent inhalational anaesthetic agents, dose-effect curves for mivacurium were determined in 84 patients scheduled for minor elective surgery during anaesthesia with 1.5 MAC (70% N2O) desflurane, sevoflurane and isoflurane and compared with those under total intravenous anaesthesia (TIVA). Acceleromyography (TOF-Guard) and train of four (TOF) stimulation of the ulnar nerve were used (2 Hz every 12 s). Mivacurium was administered in increments of 25 micrograms kg-1 until a depression of T1 > 95% was reached. ANOVA was used for statistical analysis (alpha = 0.05, beta = 0.2). The depression of T1 during potent inhalational anaesthesia was enhanced compared with TIVA. The ED50 and ED95 of mivacurium were 27 +/- 11 (SD) and 58 +/- 26 micrograms kg-1 for desflurane; 28 +/- 10 and 64 +/- 23 micrograms kg-1 for sevoflurane; and 27 +/- 13 and 55 +/- 27 micrograms kg-1 for isoflurane and were significantly lower than the 35 +/- 7 and 71 +/- 20 micrograms kg-1 for TIVA. The duration 25% revealed a significant difference between the volatile anaesthetic groups (10 +/- 2, 11 +/- 3, 11 +/- 3 min respectively) and the TIVA control group (8 +/- 3 min). The recovery index 25/75 and TOFO.80 were significantly prolonged by desflurane, sevoflurane and isoflurane compared with TIVA (RI25/75 9 +/- 4, 9 +/- 4, 10 +/- 5 respectively vs. 5 +/- 2 min; TOFO.80 27 +/- 10, 28 +/- 9, 29 +/- 9 respectively vs. 18 +/- 4 min). We conclude that the neuromuscular blocking effect of mivacurium is enhanced during anaesthesia with desflurane, isoflurane and sevoflurane compared with TIVA. The duration of action and the recovery time are prolonged. The dose of mivacurium used should be reduced if anaesthesia is maintained with volatile anaesthetics.

The purpose of this study was to examine couples' psychological responses toward husband's childbirth participation over time and to confirm the function of the curtain in the delivery room. By a quasi-experimental and prospective longitudinal study, data were collected at three points of time from 73 couples who planned to deliver their first child at one medical center in southern Taiwan. The Zung's Self-rating Anxiety scale and Zung's Self-rating Depression Scale, the Chinese Health Questionnaire, a Social Support Scale, and the Postpartum Stress Scale were used. The two-way ANOVA with repeated measures was used to compare the means of psychological responses between experimental and control groups at each point in time. The level of wife's depression was influenced by the interaction of groups and times significantly. However, the main effect of husband's childbirth participation on couples' anxiety, depression, health status, social support and the wife's postpartum stress was not found and the limitations of the study were discussed.

In this study we sought to determine the effect of sepsis on two sequelae of prolonged (24-h) beta-agonist administration, myocardial hypertrophy and catecholamine-induced cardiotoxicity. Sprague-Dawley rats were randomized to cecal ligation and perforation (CLP) or sham study groups and then further randomized to receive isoproterenol (2.4 mg. kg-1. day-1 iv) or placebo treatment. At 24 h, myocardial function was assessed by using the Langendorff isolated-heart technique or the heart processed for plain light microscopy. We found that 1) sepsis reduced contractile function, indicated by a rightward shift in the Starling curve (ANOVA with repeated measures, sepsis effect, P < 0.002); 2) sepsis-induced myocardial depression was reversed by isoproterenol treatment (isoproterenol effect, P < 0.0001); 3) sepsis reduced, but did not block, isoproterenol-induced myocardial hypertrophy (isoproterenol effect, P < 0.0001); 4) sepsis did not protect the heart from catecholamine-induced tissue injury; 5) the septic heart was protected against the effects of ischemiareperfusion (decreased postreperfusion resting tension, ANOVA with repeated measures, P < 0.01), an effect attenuated by isoproterenol treatment (P < 0.005); and 6) sepsis reduced the incidence of sustained asystole or ventricular fibrillation after ischemia-reperfusion (P < 0.05), an effect also attenuated by isoproterenol treatment (P < 0.01). We conclude that, in sepsis, beta-agonists induce changes in myocardial weight and function consistent with acute myocardial hypertrophy. These changes occur at the expense of significant tissue injury and increased sensitivity to ischemia-reperfusion-induced tissue injury.

There is limited research on the connection between the Holocaust and chronic pain, despite evidence suggesting that medical and psychological sequelae are common in survivors. The goals of this study were: (1) to define Holocaust survivors' (n = 33) chronic pain characteristics as manifested 50 years after the war, (2) to compare survivors with controls (n = 33) who did not experience World War II atrocities, and (3) to investigate the connection between past trauma and chronic pain. Data were collected through questionnaires that included a detailed medical and pain history, visual analog scale (VAS), McGill Pain Questionnaire (MPQ), Beck Depression Inventory (BDI), Symptom Check List-90 (SCL-90), and Pain Disability Index (PDI). A comparison of variables between the two groups was conducted using multivariate analysis of variance (MANOVA) and ANOVA, and canonical discriminant analysis. Results showed that Holocaust survivors reported higher pain levels (73 +/- 18 vs. 56 +/- 21; P < 0.005), more pain sites (4.5 6 2.8 vs. 2.7 6 1.4; P < 0.05), and significantly higher depression scores (17.6 +/- 8.4 vs. 9.2 +/- 4.6; P < 0.001); they tended to utilize more medical services (5.9 +/- 3.0 vs. 5.1 +/- 2.8). Nonetheless, survivors did not regard themselves more disabled as compared with controls. They reported a higher activity level as measured by walking distance capacity, and spent significantly fewer hours resting (4.3 +/- 3.6 vs. 7 +/- 4.6; P < 0.05). This paradoxical combination of high pain intensity, moderate to severe depression, and high activity level characterizes Holocaust survivors' chronic pain. It is conceivable that by remaining active Holocaust survivors fight back their pain, distress, and depression. These findings suggest that Holocaust atrocities affect survivors' chronic pain even years later.

Considering the concept that depressive disorders were not only resulting from activity of one neurotransmitter, possible interactions between the noradrenergic system and a selective serotonin uptake inhibitor, fluoxetine, were investigated in order to test the hypothesis of noradrenergic or serotonergic involvement in depression. So the biological parameters (plasma and urinary MHPG, platelet serotonin) were evaluated by HPLC. The aim of this study was to evaluate the correlations between the concentrations of MHPG and serotonin in 32 melancholic patients treated by fluoxetine (20 mg/day) during a minimum of three weeks. The clinical examination with evaluation of the antidepressant effect carried out using the HDS/MES rating scale, allowed to divide the patients into three groups: responders to treatment, partial responders and non responders. In the same time, a control group of healthy subjects was investigated. ANOVA applied to platelet serotonin at day 0 showed a tendency toward heterogeneity between the three patient groups and the control group. The concentrations of serotonin in the three patients groups were highly reduced after 21 days of treatment. Concerning plasma and urinary MHPG there was non significant difference among the three patients groups at day 0 and the control groups. After treatment by fluoxetine, the results suggest that the urinary sulfate MHPG is an indicator of the metabolism of brain norepinephrine and seems to be a better turnover indicator than the plasma sulfate MHPG. The selective evaluation of sulfate and glucuronide MHPG could give a better survey of the psychobiological state of the patients than the total MHPG evaluation.

The influence of two selective serotonin reuptake inhibitors (SSRIs), litoxetine and fluoxetine, has been studied on 5-HT4 receptor-mediated relaxation in the rat isolated oesophageal muscularis mucosae. In carbachol-precontracted oesophageal tissues, 5-hydroxytryptamine (5-HT) (0.1 nM-1 microM) induced concentration-dependent relaxations. Concentration-response curves were monophasic and reproducible. Litoxetine at concentrations without antimuscarinic properties (10 nM-1 microM) caused concentration-dependent relaxations, which reduced carbachol tone up to 37%. Higher litoxetine concentrations (3 microM-300 microM) were associated with marked relaxation up to the abolition of carbachol tone. The overall curve profile of litoxetine was biphasic in nature with a high (10 nM-1 microM) and a low (3 microM-300 microM) potency phase. Unlike 5-HT, the second curve of litoxetine was not reproducible, with a reduction involving mainly the low potency phase. Compared to litoxetine, fluoxetine caused minimal relaxation (less than 10% at 1 microM). Treatment of rats with parachlorophenylalanine (pCPA: 375 mg kg-1 per day, for two days), to deplete endogenous 5-HT stores, did not modify the relaxant effect of 5-HT, while it significantly reduced the high potency phase of litoxetine. In tissues from untreated rats, this phase was reduced by the 5-HT4 receptor antagonist GR 125487 (10 nM) to an extent similar (P = 0.20: ANOVA for continuous-by-class effects) to that induced by pCPA treatment. However, in tissues from pCPA treated animals GR 125487 (10 nM) exerted a slight but significant antagonism of litoxetine response (P = 0.037: ANOVA for continuous-by-class effects) mainly involving the high potency phase. In tissues from untreated rats, litoxetine (1 microM) increased the relaxant effects of 5-HT, while in tissues from pCPA treated animals it exerted a small but significant depression of the maximal response to 5-HT, without changing its potency value. Fluoxetine (1 microM) slightly, but significantly, antagonized the relaxant effect of 5-HT in an unsurmountable manner. In conclusion, litoxetine up to 1 microM relaxed the rat isolated oesophageal muscularis mucosae through a mechanism involving release of endogenous 5-HT, which in turn activates 5-HT4 receptors. However, based on results with GR 125487 in tissues from pCPA treated rats, a small component of litoxetine-induced relaxation may involve a direct activation of 5-HT4 receptors. It is unlikely that blockade of 5-HT reuptake can participate in the action of litoxetine, since fluoxetine, a 5-HT reuptake inhibitor equipotent to litoxetine, was ineffective in the same range of concentrations. The antimuscarinic activity of litoxetine, previously demonstrated in the isolated guinea-pig intestine, played a role at concentrations greater than 1 microM. The 5-HT-releasing action of litoxetine could account for the potentation by litoxetine of 5-HT-induced relaxation in tissues from untreated rats, which was reversed by pCPA treatment. Under these conditions, litoxetine depressed relaxations to high 5-HT concentrations only. In tissues from untreated rats, fluoxetine slightly but unsurmountably antagonized 5-HT-induced relaxations, thus confirming previous observations in the guinea-pig small intestine.

This 3-year randomized clinical trial tested the effectiveness of an interdisciplinary psychoeducational family group intervention in decreasing the caregivers' perceptions of the frequency and severity of behavioral problems in persons with dementia and their reactions to those problems, and in decreasing caregiver burden and depression. The intervention consisted of seven weekly, 2-hour multimedia training sessions that included education, family support, and skills training for 94 primary caregivers and their families. Repeated measures ANOVA was used to test for significant differences between the intervention and waiting list control groups over a 5-month period. The intervention was successful in reducing caregivers' negative reactions to disruptive behaviors and in reducing caregiver burden over time.

The major purposes of this paper are to explore the phenomena of family structure, illness symptoms, family coping and adaptation for patients with schizophrenia or manic-depression psychosis. This paper tries to provide a good reference instrument for application by nurses in home care, in order to understand and evaluate family needs. Subjects are schizophrenic or manic-depression outpatients from 3 hospitals located in northern Taiwan. Data were collected through home interview with primary caregivers and observations. There were fifty subjects from each of the 3 hospitals, and 151 subjects in total. Descriptive statistics, t-test, one way ANOVA, Pearson correlation and multiple stepwise correlation were used to analyze data. Research indicates that most patients are aged between 31 to 40, with over 10 years elapsed since onset, and are not married. Most primary caregivers are parents over 60 years old. Most family development was at the stage with young adult offspring. The manic-depressive patients have more working opportunities than schizophrenic patients. For schizophrenic patients, paranoia was the most serious in active symptoms; lack of interpersonal interaction was the most serious in negative symptoms; the other major problem was sleep disturbance in emotion-behavior assessment. Patient's disposition was the most concerning issue for families and the worst coping efficiency occurred with lazy behavior and sleep disturbance. For manic-depressive patients, aggressive behavior was the most serious active symptom, lack of energy was the most serious in negative symptom, and sleep disturbance was the most concerning problem in emotion-behavior assessment. The patient's symptom was the most concerning issue for families and the worst coping efficiency was found in drug side effect. The result also indicates that active and negative symptoms are both related to coping efficiency.
