BACKGROUND--An automated system has been developed for the detection of sound patterns suggestive of airways obstruction in long term recordings. The first step, presented here, was tracheal sound recording during histamine-induced airways obstruction. METHODS--The tracheal sounds of 29 children aged 8-19 years with asthma were recorded during airways obstruction caused by histamine inhalation using a system for continuous respiratory telemetry and computer analysis. Sound patterns were analysed, classified, and related to airways obstruction measured by lung function tests based on the forced expiratory volume in one second (FEV1). RESULTS--Five sound patterns were identified, one dominant sensitive and four specific to a fall in FEV1 of > 20%. The presence of at least one of three specific sound patterns during unforced respiration predicted a fall in FEV1 of > 20% in 87.5% of the subjects. The inspiratory and expiratory sound patterns were almost equally informative of airways obstruction. CONCLUSIONS--Wheezes can be differentiated with more precision than is currently accepted. Tracheal sound patterns are sensitive and specific predictors of histamine-induced airways obstruction. These patterns are neither invariably nor proportionally related to the results of lung function testing. However, they can be used for detection of airways obstruction on the basis of their presence or absence. 相似文献

Characteristics of couples applying for bibliotherapy via different recruitment strategies: a multivariate comparison. 总被引:1,自引:0,他引:1

This study compared characteristics of couples with different sexual dysfunctions who were recruited for participation in a bibliotherapy program via two routes: in response to media advertisements and through their presence on a waiting list for therapist-administered treatment in an outpatient sexology clinic. Data were collected from 492 subjects (246 couples). Male sexology patients were younger than media-recruited males. However, type of sexual dysfunction accounted for a substantially larger proportion of variance in the demographic and psychometric data. An interaction effect of recruitment strategy and sexual dysfunction type was found with respect to female anorgasmia. We conclude from the absence of differences between the two study groups that the Wills and DePaulo (1991) model of help-seeking behavior for mental problems does not apply to couples with sexual dysfunctions joining a bibliotherapy program who either primarily requested professional treatment or who responded to media advertising. 相似文献

OBJECTIVE: To assess relationships between hypoglycaemic awareness and diabetes-related, psychosocial and demographic characteristics. METHOD: Ninety-eight type 1 diabetic patients completed questionnaires on somatic awareness (Somatic Awareness Questionnaire, SAQ), negative affectivity (Positive And Negative Affectivity Schedule, PANAS), symptom beliefs, bustle and variety of daily life. They then performed up to 70 measurements on a hand-held computer, during 4 to 6 weeks, at home. During every measurement, they rated the presence of 20 symptoms on a 0-6 scale, and estimated and measured their blood glucose level. The percentage of recognised hypoglycaemic episodes was calculated from these data, and used as a measure of hypoglycaemic awareness. RESULTS: Hypoglycaemic awareness was negatively associated with disease duration and antecedent hypoglycaemia, and positively associated with the use of an insulin pump instead of injections, variety in the daily life, somatic awareness, sensitivity of the symptom beliefs and female gender. However, only 17% of the variance in hypoglycaemic awareness was explained. CONCLUSIONS: Psychosocial variables contribute to hypoglycaemic awareness, to a moderate but statistically significant extent. 相似文献

Sexual arousal can be viewed as an emotional state generating sex-specific autonomic and general somatic motor system responses that prepare for sexual action. In the present study modulation of spinal tendious (T) reflexes by sexual films of varying intensity was investigated. T reflexes were expected to increase as a function of increased film intensity. Through use of a between-subjects design, participants were exposed to three erotic films of low, moderate, and high intensity or to three films of moderate intensity. Self-report and genital data confirmed the induction of increasing versus stable levels of sexual arousal. Exposure to the films of increasing intensity resulted in increasing T reflexes. The results indicate that T reflex modulation is sensitive to varying levels of sexual arousal and may be of use in research on behavioral mechanisms underlying appetitive motivation. 相似文献

Background Little is known about the mechanisms explaining an increased perception of heart symptoms in congenital heart disease (ConHD).
In the present study, it was suggested that a combination of high trait anxiety and disease history increases the perception
of heart symptoms.
Purpose It was tested whether false heart cues will result in an increased perception of heart symptoms in patients with ConHD and
anxiety.
Method Thirty-six patients with ConHD and 44 healthy controls performed two exercise tasks. During one of the exercise tasks, participants
were exposed to a false heart cue consisting of false heart rate feedback (regular or irregular). Perceived heart symptoms
were assessed and heart rate, arterial partial pressure of CO2, and respirator rate were monitored continuously.
Results In line with the predictions, false heart rate feedback resulted in an increased perception of heart symptoms in high trait
anxious patients with ConHD that could not be explained by acute heart dysfunction. However, unexpectedly, this effect was
not observed immediately after the false heart rate feedback task but after a second exercise task without false feedback.
Conclusion The results suggest that not the sole presence of ConHD but ConHD in combination with high trait anxiety results in a vulnerability
to overperceive heart symptoms. 相似文献

OBJECTIVE: Findings in the literature are inconsistent on the impact of congenital heart disease (CHD) on the psychological and cognitive functioning of children and adolescents. The aim of the present study was to systematically review this empirical body of literature. METHODS: We conducted a meta-analysis to review studies on behavior problems and cognitive functioning in CHD. RESULTS: Only older children and adolescents with CHD displayed an increased risk of overall, internalizing, and to a lesser extent externalizing behavior problems. In addition, patients with severe CHD exhibited lower cognitive functioning than patients with less severe CHD, specifically with respect to performance intelligence. Moreover, decreased cognitive functioning remained relatively stable across different age groups. CONCLUSIONS: Children with severe heart disease may benefit from interventions specifically targeting perceptual organizational abilities, such as visual-spatial abilities. Moreover, older children and adolescents with CHD may benefit from psychological interventions reducing anxiety symptoms and depression. 相似文献

Long-term outcomes of memory retrieval under stress 总被引:1,自引:0,他引:1
Previous studies have found impairing effects of stress hormones on memory retrieval. So far, it is unknown whether these impairments are temporary, persistent throughout time, or whether the strength of the memory trace changes after retrieval because of the effects of stress hormones on memory processes during retrieval. In the present study, delayed cued recall (6 months after initial learning) was compared between male participants who had retrieved previously learned word pairs during stress or a control condition. Retrieval (with or without stress) had taken place either 1 day or 5 weeks after initial encoding. The group that had retrieved words under stress 5 weeks after encoding performed worse on long-term recall than the comparable control group. However, when words were retrieved under stress 1 day after encoding, no long-term effect was found, although performance at 6 months in relation to performance under stress was slightly increased compared to the control group. These results support previous findings in animals that stress may affect memory during reactivation. It further suggests that time intervals between encoding and reactivation may play an important role. 相似文献

The common genetic variation of the serotonin transporter-linked polymorphic region (5-HTTLPR) has been related to depressive symptoms, in particular after stressful life events. Although it has been investigated in the past, results suggesting that the 5-HTTLPR genotype also affects hippocampal volume are often inconsistent and it remains unclear to what extent reduced hippocampal volume is influenced by the effect of stressful life events and 5-HTTLPR genotype. Moreover, sex, which is known to affect the prevalence of depression substantially, has not been taken into account when trying to disentangle the interactive effect of common genetic variation and environmental stressors on the hippocampus. We investigated this potentially relevant three-way interaction using an automatic magnetic resonance imaging (MRI)-based segmentation of the hippocampus in 357 healthy individuals. We determined the 5-HTTLPR genotype as a biallelic locus and childhood adversity (CA) using a standard questionnaire. An interaction for hippocampal volume was found between the factors sex, genotype, and severe CA (p=0.010) as well as an interaction between genotype and severe CA (p=0.007) in men only. Post hoc tests revealed that only male S'-allele carriers with severe CA had smaller hippocampi (p=0.002). Interestingly, there was no main effect of genotype in men, while female S'-allele carriers had smaller hippocampi than L'L' carriers (p=0.023). Our results indicate that sex modulates the interactive effect of the 5-HTTLPR genotype and CA on hippocampal volume. While the S'-allele is associated with hippocampal volume independent of CA in women, men only have smaller hippocampi if they carry the risk allele and experienced severe CA. 相似文献
