Introduction

Celiac disease is estimated to affect between 1 in 100 and 1 in 300 Caucasian subjects. Many quantitative studies have explored the issues encountered by these subjects; however, few studies have addressed the subjective and experiential dimensions of celiac disease.

Objective

The objective of this qualitative exploratory study is to expand current knowledge concerning the subjective experience of celiac disease and of a gluten-free diet in subjects diagnosed with celiac disease in adulthood.

Method

Data was collected through non-directive interviews with 14 subjects aged between 28 and 53 (M = 41.7, SD = 7.48).

Results

An interpretive phenomenological analysis identified various themes related to the experience of illness: (1) history of the disease, (2) symptoms, (3) nutrition, (4) perception of medical experiences, (5) relationships with family and friends, (6) psychological implications, and (7) consequences for daily living.

Conclusion

The results show the importance of developing a “mythology” (concerning the disease's origin) to enable the inclusion of the condition in the individual's on-going personal story.  相似文献

To investigate the prevalence of fatigue, the relationship between sickness or injury within two weeks, chronic diseases and fatigue among adults aged 18–45 years. Thousand five hundred and seventy nine individuals were included in this cross-sectional study. The Chalder Fatigue Scale (CFS) was used to assess fatigue defined as CFS score ≥4. The prevalence of fatigue was 25% in this study. Our results showed that only sickness or injury within two weeks (odds ratio [OR]: 2.440) and chronic diseases (OR: 1.727) were significantly related to fatigue. Moreover, their ORs for fatigue remained the same in all models (binary logistic regression models with adjusting for demographic and health-related characteristics one by one). In conclusion, fatigue was prevalent among adults aged 18–45 years. Sickness or injury within two weeks and chronic diseases were the risk factors for fatigue independent of demographic and health-related characteristics.  相似文献

Object decision (OD) test is one subtest of the Birmingham Object Recognition Battery (BORB). It is useful for differential diagnosis among several neurodegenerative diseases. However, normative data provided with this battery count on very few subjects and do not control for the effect of age, which limits interpretability. The purpose of Study 1 was to provide normative data for the OD test of the BORB (version A—hard). The objectives of Study 2 were to establish the diagnostic validity of this task and predictive validity of the normative data in the case of the semantic variant of primary progressive aphasia (svPPA) and Alzheimer’s disease (AD).Based on multiple linear regressions, equations to calculate Z-scores corrected for age were provided for 130 participants aged from 47 to 89 years. Performance of 20 healthy participants was compared to that of 14 individuals with svPPA and 18 with AD. After controlling for confounders, participants with svPPA had a lower total score than controls and AD participants. AD participants had a poorer performance than controls only when chimeric objects were considered. Among those with a deficit on the total score of the test, 94% (17/18, including 12 with svPPA) were correctly identified as having a pathological condition (svPPA or AD). This test could help refine differential diagnosis between svPPA and AD patients, especially before the deficits of episodic memory show up.  相似文献

由于近十年来经皮介入治疗技术的巨大进展,肾血管病(renovascular disease,RVD)患者中接受经皮肾动脉成形治疗的数量迅速增加,已作为纠正严重肾动脉狭窄的首选措施逐步被接受。但目前对粥样硬化性肾动脉狭窄尚无公认的最优治疗,选择经皮介入重建肾动脉血流还是单纯药物保守治疗在学术界尚有争议。现系统评述目前临床...  相似文献
