Oral cancer is a common cancer with poor prognosis. We evaluated the expression of PBK/TOPK (PDZ-binding kinase/T-LAK cell-originated protein kinase) and its prognostic significance in oral cancer. PBK/TOPK expression was measured by immunohistochemical staining of samples from 287 patients with oral cancer. The association between PBK/TOPK expression and clinicopathological features was analyzed. The prognostic value of PBK/TOPK for overall survival was determined by Kaplan-Meier analysis and Cox proportional hazard models. A high PBK/TOPK expression level was correlated with long overall survival. The prognostic role of PBK/TOPK expression was significant in young patients (p < 0.05), patients with smoking habits (p < 0.05), and late stage disease (p < 0.05). Our results suggest that PBK/TOPK expression is enhanced in oral cancer. High PBK/TOPK expression, either alone or in subgroups according to clinicopathological features, may serve as a favorable prognostic marker for patients with oral cancer.
Gender is an important risk factor in predicting chronic kidney disease (CKD); however, it is under-researched. The purpose of this study was to examine whether gender differences affect the risk factors of early CKD prediction. This study used data from 19,270 adult health screenings, including 5101 with CKD, to screen for 11 independent variables selected as risk factors and to test for the significant effects of statistical Chi-square test variables, using seven machine learning techniques to train the predictive models. Performance indicators included classification accuracy, sensitivity, specificity, and precision. Unbalanced category issues were addressed using three extraction methods: manual sampling, the synthetic minority oversampling technique, and SpreadSubsample. The Chi-square test revealed statistically significant results (p < 0.001) for gender, age, red blood cell count in urine, urine protein (PRO) content, and the PRO-to-urinary creatinine ratio. In terms of classifier prediction performance, the manual extraction method, logistic regression, exhibited the highest average prediction accuracy rate (0.8053) for men, whereas the manual extraction method, linear discriminant analysis, demonstrated the highest average prediction accuracy rate (0.8485) for women. The clinical features of a normal or abnormal PRO-to-urinary creatinine ratio indicated that PRO ratio, age, and urine red blood cell count are the most important risk factors with which to predict CKD in both genders. As a result, this study proposes a prediction model with acceptable prediction accuracy. The model supports doctors in diagnosis and treatment and achieves the goal of early detection and treatment. Based on the evidence-based medicine, machine learning methods are used to develop predictive model in this study. The model has proven to support the prediction of early clinical risk of CKD as much as possible to improve the efficacy and quality of clinical decision making.
Empty nose syndrome (ENS) is a rare entity in patients who undergo sinonasal surgery due to over-resection of the turbinate. This syndrome leads to debilitating symptoms that include dry nose, painful nasal breathing, paradoxical nasal obstruction, crusting, and sleep disorder. The goal of surgical treatment is to reestablish the volume of the turbinates to rehabilitate the nasal resistance. Endonasal microplasty with cartilage implants on the lateral wall of the nasal cavity is useful for creating the neoturbinate. Here, we present 2 cases that describe the management of empty nose syndrome by endonasal microplasty using platelet-rich fibrin (PRF) scaffolds embedded with a diced cartilage graft. The integration of the PRF scaffolds with diced cartilage efficiently facilitated the reestablishment of the neoturbinate. This autologous biomaterial is suitable for the treatment of ENS.
Objective: In this study, patients with head and neck adenoid cystic carcinoma were investigated with respect to disease characteristics, treatments, and potentially prognostic variables. Materials and Methods: Between January 1995 and December 2010, 29 patients with ACC of the head and neck treated at our institution were retrospectively reviewed. Results: The 29 patients had a mean age of 54.7 years. Of the 29 patients, 4 (13.8%) underwent surgical resection only, 21 (72.4%) underwent surgery with radiotherapy, and 4 (13.8%) received postoperative chemoradiotherapy. Of 9 patients (31.0%) who experienced a recurrence within the follow-up period, 3 (10.3%) had local recurrence and 5 (17.2%) had distant metastasis; 1 (3.4%) patient had both local recurrence and distant metastatic spread. Conclusion: ACC is a relatively rare tumor associated with long survival, even in metastatic settings. Despite aggressive therapy with surgery, radiotherapy, and chemotherapy, a marked potential for local and distant recurrence still remains.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
