Irritable bowel syndrome(IBS)is regarded as a multifactorial disease in which alterations in the brain-gut axis signaling play a major role.The biopsychosocial model applied to the understanding of IBS pathophysiology assumes that psychosocial factors,interacting with peripheral/central neuroendocrine and immune changes,may induce symptoms of IBS,modulate symptom severity,influence illness experience and quality of life,and affect outcome.The present review focuses on the role of negative affects,including depression,anxiety,and anger,on pathogenesis and clinical expression of IBS.The potential role of the autonomic nervous system,stress-hormone system,and immune system in the pathophysiology of both negative affects and IBS are taken into account.Psychiatric comorbidity and subclinical variations in levels of depression,anxiety,and anger are further discussed in relation to the main pathophysiological and symptomatic correlates of IBS,such as sensorimotor functions,gut microbiota,inflammation/immunity,and symptom reporting. 相似文献
Adolescent smoking is a major public health problem. While the socioeconomic status (SES) of the neighbourhood and that of the family are known to play a role in smoking onset and progression, it is not clear whether it modifies the association between parental influences and adolescent behaviour. The purpose of this study is to investigate family correlates of adolescent smoking experimentation and to explore the modifying role of socioeconomic context and European geographical area in a sample of European adolescents. This is a secondary analysis of the baseline survey of the European Drug Addiction Prevention (EU-Dap) trial which took place in seven European countries and involved 7079 students. School SES was used as indicator of socioeconomic context. European countries were aggregated in two geographical areas: North-Central and South. The associations between parental, family factors, and adolescents smoking experimentation were analysed through multilevel mixed-effect logistic regression models, stratified by school SES and European geographical area. Parental smoking, permissiveness towards tobacco, family conflicts, problematic relationships, low connectedness, and low parental control were significantly associated with adolescent smoking experimentation. Paternal smoking was a stronger correlate of adolescent smoking in low SES schools, while maternal smoking in high SES schools. Parental permissiveness was a stronger correlate in low SES schools. Family conflicts and low parental control were correlates only in low SES schools. The associations did not substantially differ between European geographical areas, with the exception of parental smoking that was a stronger correlate in the North, and parental control that was a correlate only in the South of Europe. To reduce inequalities in tobacco-related outcomes, prevention efforts in low socioeconomic contexts appear to be a public health priority. Parental smoking, permissiveness, family relationships, and connectedness should be addressed in preventive programs.
The aim of the present study was to evaluate the effects of a Global Postural Rehabilitation (GPR) program on motor symptoms and gait parameters of patients with Parkinson’s disease (PD) by means of three-dimensional motion analysis study. Ten subjects with clinical diagnosis of PD were enrolled (study group). Age-, sex- and disease duration-matched PD patients were recruited as a control group (no treatment). Three-dimensional motion analysis was conducted by means of a stereophotogrammetric system. After basal evaluation, the study group underwent a specific rehabilitation program consisting of individual 40?min GPR daily sessions, 3?days a week for 4 consecutive weeks. Neurological status and spatiotemporal gait parameters of the two groups were evaluated at study entry (t0), at 4?weeks (t1, end of rehabilitation protocol) and at 8 and 12?weeks (t2 and t3, follow-up evaluation). At baseline evaluation, the two groups did not differ in clinical features and gait parameters. At the end of rehabilitation protocol (t1) and at follow-up evaluation (t2 and t3), a significant improvement in temporal gait parameters and UPDRS scores was observed in all treated patients as compared to baseline and controls. Our preliminary findings showed that significant improvements in mobility and gait parameters of PD patients can be obtained through GPR treatment, with a parallel improvement in clinical status. Quantitative analysis of gait pattern can be considered a useful tool to assess the efficacy of rehabilitation interventions in patients affected by PD. 相似文献
