Fatigue is a complex phenomenon that can be difficult to quantify due to the various physiological and psychological factors involved. However, fatigue can significantly impact a range of quality-of-life areas for those with a respiratory condition. Our aim is to understand if there are any clinical or research needs relating to fatigue for young people with chILD. This qualitative, non-clinical study explores the lived experience of fatigue in young people with chILD. Fifteen participants comprising child-parent dyads (n = 2), young adults (n = 4) and parents (n = 9) were recruited from chILD patient organisations and online communities. We focused on the experience of fatigue in terms of how it is communicated, the symptoms, and their impact. We explored whether any factors led to the young person being motivated to push beyond fatigue. Data was analysed by constructivist grounded theory. There were three main themes of interest: (i) the experience of fatigue that includes reporting abnormal weakness and behavioural affect; (ii) the consequences of fatigue, such as its impact on education, society, and quality-of-life; (iii) motivational strategies and supportive measures that help young people manage their fatigue. Fatigue is a complex, multi-dimensional phenomenon for those living with chILD. For future work, we recommend incorporating the discussion of fatigue into clinic settings to assess any quality-of-life burden factors alongside living with chILD.</p>","PeriodicalId":19651,"journal":{"name":"Orphanet Journal of Rare Diseases","volume":"20 1","pages":"151"},"PeriodicalIF":3.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143764525","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Unaffected embryos, which degenerated during blastomere-blastocyst transformation, may give birth if transferred before the blastocyst stage and may be of great value to women with a low oocyte count.

It poses a risk of progression to hepatocellular adenoma (HCA) and hepatocellular carcinoma. While ultrasonography is the primary imaging modality to monitor liver health, it has limitations in assessing liver size and detecting HCAs, which can be addressed by magnetic resonance imaging (MRI). This study was conducted to evaluate the efficacy of MRI in the proactive management of GSD and its ability to predict HCA.</p><p><strong>Methods: </strong>This study included 32 patients with GSD from Wonju Severance Christian Hospital, of whom 29 underwent MRI examinations. Baseline characteristics, such as sex, height, weight, and body surface area (BSA), were recorded, along with laboratory markers. The MRI protocols included T2-weighted axial and coronal imaging, proton magnetic resonance spectroscopy, multi-echo Dixon imaging, magnetic resonance elastography, and T1 mapping. The correlation between liver volumes and laboratory results was analyzed, and logistic regression was used to analyze the association between the liver volume/BSA ratio and adenoma occurrence.</p><p><strong>Results: </strong>A significant correlation was observed between a high liver volume-to-BSA ratio and the likelihood of HCA development. Receiver operating characteristic curve analysis showed an area under the curve of 0.816 for predicting HCAs and a C-index of 0.847, indicating that MRI had high predictive accuracy. For each unit increase in the liver volume-to-BSA ratio, the probability of HCA increased by 1.005.</p><p><strong>Conclusion: </strong>MRI is valuable for assessing adenoma formation in patients with GSD. Although not intended for routine surveillance of all patients, MRI can be selectively used in high-risk cases to enable early detection and timely intervention, thereby reducing the risk of progression to malignant transformation.</p>","PeriodicalId":19651,"journal":{"name":"Orphanet Journal of Rare Diseases","volume":"20 1","pages":"144"},"PeriodicalIF":3.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11948790/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143731041","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
