BackgroundGiven the uncertainties regarding thyroid nodule assessment and management, physicians require systematically and transparently developed recommendations. This systematic review assesses the quality and consistency of the recommendations of international clinical practice guidelines (CPGs) for the diagnosis and management of thyroid nodules and cancer to assist physicians in making appropriate recommendations.MethodsThe CPGs on the management of thyroid nodules and cancer published before June 2013 were retrieved. All the reviewed guidelines were in English. Four reviewers independently assessed the rigor of guideline development by using the Appraisal of Guidelines Research and Evaluation II (AGREE-II) instrument, and their reported evidence was evaluated.ResultsTen eligible guidelines were included: nine had been developed by professional organizations, and the remaining guideline was endorsed by an independent regional body. Three guidelines achieved a score of greater than 50% in all six AGREE-II domains. Guidelines scored highest on the measurement of ‘scope and purpose’ (≥61.1% for eight CPGs) and lowest on the measurement of ‘applicability’ (≤38.5% for five CPGs). The overall quality ranged from 3.0 to 6.25 on a seven-point scale on the AGREE-II tool. Most CPG recommendations on the management of thyroid cancer were relatively consistent. Guidelines varied regarding the indication of fine-needle aspiration for thyroid nodules, as well as in their suggestions for postoperative radioiodine ablation.ConclusionsOur analysis showed that the current CPGs varied in methodological quality. More effort is needed to improve the quality of recommendations on the diagnosis and management of thyroid nodules and cancer.

Purpose: Hepatocellular carcinoma (HCC) is the second leading cause of cancer mortality worldwide. Sleep problems are common in HCC patients and may be attributable to disturbances in the circadian rhythm. Research into the role of circadian rhythms in sleep quality among HCC patients is lacking, however. This study investigated the relationship between the diurnal cortisol profile and sleep quality among HCC patients. We aimed to identify alterations in the diurnal cortisol profile in patients with HCC compared to healthy controls and investigate whether they were associated with poor sleep quality among HCC patients. Methods: Participants comprised 75 HCC patients and 33 healthy individuals. The Taiwanese version of the Pittsburgh Sleep Quality Index (PSQI-T) was administered to assess sleep quality. Saliva samples were collected on 3 consecutive days at five time points daily to measure diurnal cortisol levels. Results: In the HCC group, 89.3% of individuals were poor sleepers (PSQI-T > 5), whereas among healthy individuals, 30.3% were poor sleepers. While the healthy participants’ diurnal cortisol profile followed a typical pattern that peaked 30 min after waking and declined gradually throughout the day, the cortisol level in the HCC patients rebounded at bedtime. Higher cortisol levels were marginally correlated with poor sleep quality ( OR = 1.00007, p < .05). Conclusions: Our study suggests a potential association between disturbed circadian rhythm and poor sleep quality in HCC patients. Further investigation of the causal relationship between sleep and circadian rhythm is warranted.

BackgroundPatients with breast cancer often exhibit high levels of anxiety and depression and a considerable decrease in their ability to participate in leisure activities, which result in the long-term disruption of their daily lives. This study intended to explore the relationships among anxiety, leisure constraints, and depression and evaluate whether depression mediates the effects of anxiety on leisure constraints in patients with breast cancer.MethodThis prospective study included 106 patients with breast cancer. All the patients completed the Taiwanese version of the Hospital Anxiety and Depression Scale and Leisure constraints questionnaire. Path analysis was used to test the mediating role of depression.ResultsLeisure constraints, anxiety, and depression were positively interrelated and co-occurred in the patients. The accelerated bootstrapping confidence intervals of the indirect effect did not include zero (0.276–1.663). Moreover, depression completely mediated the effects of anxiety on leisure constraints in patients with earlier cancer stages but not in patients with advanced cancer stages.ConclusionsDepression is a crucial mechanism underlying the relationship between anxiety and leisure constraints in patients with breast cancer. Although many patients experience minimal disruption of activities and roles during survivorship, they are unable to perform functional activities and satisfactorily play their roles. This is the first study to explore leisure constraints in patients with breast cancer and investigate the mediating role of depression that underlies the relationship between anxiety and leisure constraints. The current findings are clinically crucial because they suggest the need to consider the simultaneous management of anxiety and depression for alleviating leisure constraints.
