PurposeTo characterize the impact of comorbidity on survival outcomes for patients with nasopharyngeal carcinoma (NPC) post radiotherapy (RT).MethodsA total of 4095 patients with NPC treated by RT or RT plus chemotherapy (CT) in the period from 2007 to 2011 were included through Taiwan’s National Health Insurance Research Database. Information on comorbidity present prior to the NPC diagnosis was obtained and adapted to the Charlson Comorbidity Index (CCI), Age-Adjusted Charlson Comorbidity Index (ACCI) and a revised head and neck comorbidity index (HN-CCI). The prevalence of comorbidity and the influence on survival were calculated and analyzed.ResultsMost of the patients (75%) were male (age 51±13 years) and 2470 of them (60%) had at least one comorbid condition. The most common comorbid condition was diabetes mellitus. According to these three different comorbidity index (CCI, ACCI and HN-CCI), higher scores were associated with worse overall survival (P< 0.001). The Receiver Operating Characteristic (ROC) curve was used to assess the discriminating ability of CCI, AACI and HN-CCI scores and it demonstrated the predictive ability for mortality with the ACCI (0.693, 95% CI 0.670–0.715) was superior to that of the CCI (0.619, 95% CI 0.593–0.644) and HN-CCI (0.545, 95%CI 0.519–0.570).ConclusionComorbidities greatly influenced the clinical presentations, therapeutic interventions, and outcomes of patients with NPC post RT. Higher comorbidity index scores accurately was associated with worse survival. The ACCI seems to be a more appropriate prognostic indicator and should be considered in further clinical studies.

A diagnosis of HCh may indicate an independent risk for ISSNHL. This finding suggests that an underlying vascular mechanism contributes to the development of ISSNHL. We suggest that physicians counsel patients with HCh to seek medical attention if they have hearing impairments, because they may also have an increased risk of developing ISSNHL.

BACKGROUND: Homeobox (HOX) genes are expressed in adult cells and regulate expression of genes involved in cell proliferation as well as cell-cell and cell-extracellular matrix interactions. Dysregulation of HOX gene expression plays important roles in carcinogenesis in a variety of organs. Through data mining on a published transcriptome dataset, this study first identified Homeobox protein Hox-C6 (HOXC6) gene as one of the differentially upregulated genes in nasopharyngeal carcinoma (NPC). We aimed to evaluate HOXC6 expression and its prognostic effect in a large cohort of NPC patients.METHODS: We retrospectively examined the HOXC6 expression and Ki-67 index by immunohistochemistry in biopsy specimens from 124 patients with non-metastasized NPC. The results were correlated with the clinicopathological variables including disease-specific survival (DSS), metastasis-free survival (MeFS), and local recurrence-free survival (LRFS).RESULTS: HOXC6 high expression was positively correlated with increased Ki-67 labeling index, and significantly associated with increment of tumor stage (p=0.024), advanced nodal status (p<0.001) and American Joint Committee on Cancer (AJCC) stage (p=0.002). Its expression also correlated with worse prognosis in terms of DSS (p=0.008), MeFS (p=0.0047) univariately. In multivariate analyses, HOXC6 expression still remained prognostically independent to portend worse DSS (p=0.015, hazard ratio=1.988) and MeFS (p=0.036, hazard ratio=1.899), together with stage III-IV (p=0.024, DSS; p=0.043, MeFS).CONCLUSION: In summary, our results suggest HOXC6 may play a critical role in NPC progression and may serve as a potential prognostic biomarker in NPC patients.

We found a 2.16-fold higher risk of HNMs in patients diagnosed with SLE compared with the risk of first malignancy in the age-matched controls (incidence rate ratio, IRR = 2.16, p < 0.05). The site with the highest incidence of HNMs in SLE patients was the oral cavity (5/11, 45.45%), followed by the nasopharynx (4/11, 36.36%). SLE displayed no synergic effect on the survival of SLE patients with an HNM compared with age-matched controls with a new HNM (p = 0.2446).

Rsf-1 overexpression is common and is associated with adverse prognosticators and therapeutic response, which confers tumour aggressiveness through chromatin remodelling, and represents a potential prognostic biomarker in NPC.

Background: Through data mining from the public transcriptome of NPC, cyclin-dependent kinase inhibitor 3 (CDKN3) was identified as a significantly upregulated gene in NPC. CDKN3 functions as a key factor in cell cycle regulation. This study was aimed to investigate the expression of CDKN3 in NPC tissues and its prognostic significance.Methods: Immunohistochemistry was performed for 124 NPC patients to assess the protein expression of CDKN3. The stainings of CDKN3 were scored by using H-score method. The relationships between CDKN3 expression status and clinicopathological parameters, disease-specific survival (DSS), distant metastasis-free survival (DMeFS), and local recurrence-free survival (LRFS) were statistically analyzed.Results: High expression of CDKN3 was significantly associated with higher primary nodal status (P=0.030) and higher TNM stage (P=0.019). In univariate analysis, high expression of CDKN3 predicted worse DSS (P<0.0001), DMeFS (P<0.0001), and LRFS (P<0.0001). In multivariate analysis, CDKN3 overexpression still acted as an independent prognostic factor for worse DSS (P<0.001; hazard ratio [HR]=11.999, 95% CI: 5.378-26.771), DMeFS (P<0.001; HR=15.069, 95% CI: 5.884-38.592), and LRFS (P<0.001; HR=5.000, 95% CI: 2.312-10.815).Conclusion: High expression of CDKN3 was an independent negative prognostic factor for NPC and was associated with advanced disease status. It might serve as potential therapeutic target and aid in risk stratification for patients with NPC.

Aims:To evaluate the effect of earplugs and eye masks on the sleep quality of patients in intensive care unit (ICU).Design: Systematic review and meta-analysis.Data Sources: Randomized controlled trial studies conducted before May 5, 2020 were searched for in Embase, MEDLINE, Cochrane Library, CINAHL and Index to Taiwan Periodical Literature System databases.Review Methods: Analyses in this study were according to the PRISMA statement.The heterogeneity of the data was investigated through sub-group analysis while a meta-analysis was performed using the Review Manager 5.3 software.Results: A total of 797 patients from 13 studies were included in this study. Without considering alone or combined use of earplugs and eye masks, the meta-analysis supported that there was a significant effect on self-reported sleep quality. The overall standardized mean difference of the effect size was 1.44 (95% confidence interval [CI]: [0.80, 2.09]). Sub-group analysis indicated that the use of earplugs alone had no significant effect on sleep quality (effect size: 0.07, 95% [CI]: [−0.50, 0.64]). The use of eye masks alone had a significant effect on sleep quality (effect size: 1.56, 95% [CI]:[1.08, 2.05]). The use of both earplugs and eye masks proved to have the largest effect size on sleep quality (effect size: 2.08, 95% [CI]: [0.95, 3.21]). Conclusion:The combined use of earplugs and eye masks or the standalone use of eye masks is a non-invasive, economical and effective way to promote sleep quality in adult ICU patients.Impact: Clinical nurses could use this meta-analysis as it recommends that nurses provide adult ICU patients with either one or both earplugs and eye masks to improve the patients' sleep quality. Study Registration:The review protocol was registered a priori and published online in the PROSPERO database of systematic reviews (www.crd.York.ac.uk/Prospero with the registration number # CRD42021221185).
