Medical outcome in asthmatic patients: effects of airways hyperreactivity and symptom-focused anxiety. 总被引:3,自引:0,他引:3

Hypotheses about medical outcome in asthma, indexed by rates of rehospitalization within 6 months after discharge from long-term intensive care, were evaluated. Predictions for rehospitalization were based on the levels of airways hyperreactivity, indexed by inhalation challenges with histamine or methacholine, and levels of anxiety focused upon and concurrent with periods of asthmatic distress, indexed by Panic-Fear symptomatology. Results indicated that, although some prediction could be made on the basis of levels of anxiety and airways hyperreactivity alone, the best predictions resulted from the combined effects of these factors. Almost half of the patients who had highly hyperreactive airways and a tendency to disregard symptoms of breathing difficulty were rehospitalized. By comparison, none of the patients who had less hyperreactive airways and a tendency to be vigilant about their symptoms were rehospitalized. The hypotheses and results are discussed with respect to symptom-focused and general, illness-dependent types of anxiety which have different effects upon medical outcome in chronic asthma. The results have implications for the application of anxiety-reducing forms of intervention in asthma. 相似文献

During training to relax the frontalis muscle, continuous biofeedback (BF) was compared to discrete verbal feedback (VF) delivered immediately after each trial. Both feedback modalities were based on frontalis electromyographic (EMG) activity. Training consisted of 3 consecutive daily session-each comprised of 3 baseline (nonfeedback) trials followed by 10 training trials of 128 see. The presence or absence of the two informationally positive feedback modalities were combined factorially to define four training conditions: BF + VF, NO BF + VF, BF + NO VF, and NO BF + NO VF. Results indicated that while VF alone facilitated muscle relaxation, BF was clearly prepotent ill effecting consistent decreases in EMG activity both across trials and days of training. Additionally, the facilitating effect of BF transferred to nonfeedback trials while VF did not affect performance on nonfeedback trials. Finally, accuracy of self-evaluations of performance on a trial by trial basis was markedly improved by BF, while VF improved accuracy only for trials having a very large absolute difference between levels of EMG activity. Ss receiving no feedback neither reduced muscle tension during training not were able to evaluate their performance accurately even when large absolute differences occurred between trials in frontalis EMG activity. 相似文献

Toxicogenic and psychogenic theories have been proposed to explain idiopathic environmental intolerance (IEI). Part 2 of this article is an evidence-based causality analysis of the psychogenic theory using an extended version of Bradford Hill's criteria. The psychogenic theory meets all of the criteria directly or indirectly and is characterised by a progressive research programme including double-blind, placebo-controlled provocation challenge studies. We conclude that IEI is a belief characterised by an overvalued idea of toxic attribution of symptoms and disability, fulfilling criteria for a somatoform disorder and a functional somatic syndrome. A neurobiological diathesis similar to anxiety, specifically panic disorder, is a neurobiologically plausible mechanism to explain triggered reactions to ambient doses of environmental agents, real or perceived. In addition, there is a cognitively mediated fear response mechanism characterised by vigilance for perceived exposures and bodily sensations that are subsequently amplified in the process of learned sensitivity. Implications for the assessment and treatment of patients are presented. 相似文献

The psychogenic theory presupposes that idiopathic environmental intolerance (IEI) is an overvalued idea explained by psychological and psychosocial processes. The polysomatic symptoms are amplifications of complaints common to the general population, psychophysiological manifestations of stress and the stress-response, or symptoms of psychiatric clinical syndromes. The psychogenic theory is supported by provocation challenge studies which demonstrate that appraisals of ‘reactions’ are unreliable and cognitively mediated. Clinical studies of IEI cases consistently identify greater incidence of current and premorbid lifetime psychiatric disorders and co-morbidity with functional somatic syndromes that are fashionable ‘diagnoses’. The toxicogenic theory presupposes low-level chemical sensitivity or intolerance without objective signs to a plethora of diverse chemical agents. Symptoms are synonymous with disease and attributions are synonymous with cause. Hypotheses about physiological processes and mechanisms are implausible and unsupported by evidence. Advocates claim this phenomenon is so ephemeral that the principles and methods of toxicology do not apply and that a scientific paradigm shift is in order. 相似文献

A self-help education-exercise program for asthmatic children and their parents was evaluated in Denver, Colorado. The objective of the program was to instill better self-care practices in the child which are expected to reduce utilization and cost of medical services and reduce the amount of interference in the child's normal activities. The program was designed to educate the family about the nature of asthma and its treatment, the importance of self-responsibility for the child, and the psychosocial aspects which may affect both the child and the parents in a family with an asthmatic child. The program also included specific lessons pertaining to self-care practices including general health exercises on land and in water, relaxation training, and diaphragmatic breathing. The results of subjective evaluations of the parents indicated that the program was successful in achieving its goals to: Reduce the number of severe attacks, reduce medication usage, improve compliance, reduce days of school missed, increase exercise activity, and control wheezing by the steps taught in the course. While the results are suggestive, a further, controlled evaluation of the program is recommended. 相似文献

This review proposes that the emerging acceptance of the hormetic dose-response model in toxicology and pharmacology has the potential to significantly change important aspects of drug development. Two situations where the hormesis concept may affect drug development are considered: one in which low-dose stimulation may represent an adverse/unwanted effect (eg, stimulation of tumor cell proliferation by antitumor drugs), the other in which low-dose stimulation defines the therapeutic zone (ie, a beneficial or intended effect; eg, cognition enhancement in Alzheimer's disease treatment). Examples are used to demonstrate that the hormetic dose-response model has implications for the definition of an ideal candidate for a therapeutic agent, as well as implications for study designs needed to assess the quantitative features of the dose-response relationship. 相似文献

ObjectivesTo identify factors associated with 30-day all-cause readmission rates in surgical patients discharged to skilled nursing facilities (SNFs), and derive and validate a risk score.DesignRetrospective cohort.Setting and participantsPatients admitted to 1 tertiary hospital's surgical services between January 1, 2011, and December 31, 2014 and subsequently discharged to 110 SNFs within a 25-mile radius of the hospital. The first 2 years were used for the derivation set and the last 2 for validation.MethodsData were collected on 30-day all cause readmissions, patient demographics, procedure and surgical service, comorbidities, laboratory tests, and prior health care utilization. Multivariate regression was used to identify risk factors for readmission.ResultsDuring the study period, 2405 surgical patients were discharged to 110 SNFs, and 519 (21.6%) of these patients experienced readmission within 30 days. In a multivariable regression model, hospital length of stay [odds ratio (OR) per day: 1.03, 95% confidence interval (CI) 1.02-1.04], number of hospitalizations in past year (OR 1.24 per hospitalization, 95% CI 1.18-1.31), nonelective surgery (OR 1.33, 95% CI 1.18-1.65), low-risk service (orthopedic/spine service) (OR 0.32, 95% CI 0.25-0.42), and intermediate-risk service (cardiothoracic surgery/urology/gynecology/ear, nose, throat) (OR 0.69, 95% CI 0.53-0.88) were associated with all-cause readmissions. The model had a C index of 0.71 in the validation set. Using the following risk score [0.8 × (hospital length of stay) + 7 × (number of hospitalizations in past year) +10 for nonelective surgery, +36 for high-risk surgery, and +20 for intermediate-risk surgery], a score of >40 identified patients at high risk of 30-day readmission (35.8% vs 12.6%, P < .001).Conclusions/ImplicationsAmong surgical patients discharged to an SNF, a simple risk score with 4 parameters can accurately predict the risk of 30-day readmission. 相似文献
