The use of adjunctive traditional Chinese medicine therapy and survival outcome in patients with head and neck cancer: a nationwide population-based cohort study.

BACKGROUND Traditional Chinese medicine (TCM) is widely used in the treatment of patients with several types of cancer. However, no large-scale clinical studies have evaluated whether TCM is associated with better survival in patients with head and neck cancer (HNC). METHODS The Taiwan National Health Insurance Research Database was used to conduct a retrospective cohort study of patients with HNC between 2001 and 2011. The patients with HNC were separated into TCM users and non-users, and Cox regression models were applied to determine the association between the use of TCM and survival outcome. RESULTS The TCM and comparison cohorts comprised data for 2966 and 2670 patients, respectively. The mean age was 51.3 years in the TCM cohort and 51.7 years in the comparison cohort. Multivariate analysis demonstrated that the use of TCM was significantly associated with lower risk of all-cause mortality by 32% (adjusted hazard ratio, 0.68; 95% confidence interval, 0.62-0.75). Patients with longer TCM use had a lower mortality rate (P for trend < 0.001). CONCLUSIONS Our study showed that adjunctive therapy with TCM is associated with higher survival outcome. However, some limitations exist, such as the lack of information of cancer stage. In addition, causality cannot be assessed with this retrospective study. A randomized controlled trial to test the effect of adjunctive TCM therapy in HNC patients is needed.

New-onset atrial fibrillation-related ischemic stroke occurring after hospital discharge in septicemia survivors

Background Sepsis will induce stroke, new-onset atrial fibrillation (AF) increase ischemic stroke (IS) in in-hospitalization and long-term period after sepsis. Physicians must alert this condition and given suitable treatment. Aim The associated of IS and new-onset AF in septicemia survivors after discharge have to be evaluated. Design The inpatient data was used of the Taiwan National Health Insurance Database (NHIRD) in 2010. We identified patients suffered their first occurrence of septicemia (International Classification of Disease, Ninth Revision, Clinical Modification [ICD-9-CM] is 038, 003.1, 036.1) and excluded less than 18 years old. Patients had AF (ICD-9-CM to 427.3×) during the same admission or after septicemia hospitalization discharged were defined as new-onset AF. The outcome was IS happened after septicemia discharge (ICD-9-CM as 433-437). Methods The factors related to IS after septicemia survival were established using multivariate logistic regression with forward stepwise selection. Results There were 1286 new-onset AF and 1026 IS happened after septicemia discharge. The crude odds ratio (OR) were 3.88 (95% confidence interval [C.I.]: 1.69-8.89) and 1.62 (95% C.I.: 1.14-2.3) in middle-aged and elderly septicemia survivors with new-onset AF induced IS. The risk of IS after septicemia survivors was noticed adjusted OR 1.74 (95% C.I.: 1.26-2.41) for new-onset AF. Conclusion The middle-aged and elderly septicemia survivors suffered from new-onset AF had increased incidence of IS within three months. New-onset AF was a mediator factor of IS in septicemia survivors of Asian population.

Risk analysis of colorectal cancer incidence by gene expression analysis

Background Colorectal cancer (CRC) is one of the leading cancers worldwide. Several studies have performed microarray data analyses for cancer classification and prognostic analyses. Microarray assays also enable the identification of gene signatures for molecular characterization and treatment prediction. Objective Microarray gene expression data from the online Gene Expression Omnibus (GEO) database were used to to distinguish colorectal cancer from normal colon tissue samples. Methods We collected microarray data from the GEO database to establish colorectal cancer microarray gene expression datasets for a combined analysis. Using the Prediction Analysis for Microarrays (PAM) method and the GSEA MSigDB resource, we analyzed the 14,698 genes that were identified through an examination of their expression values between normal and tumor tissues. Results Ten genes (ABCG2, AQP8, SPIB, CA7, CLDN8, SCNN1B, SLC30A10, CD177, PADI2, and TGFBI) were found to be good indicators of the candidate genes that correlate with CRC. From these selected genes, an average of six significant genes were obtained using the PAM method, with an accuracy rate of 95%. The results demonstrate the potential of utilizing a model with the PAM method for data mining. After a detailed review of the published reports, the results confirmed that the screened candidate genes are good indicators for cancer risk analysis using the PAM method. Conclusions Six genes were selected with 95% accuracy to effectively classify normal and colorectal cancer tissues. We hope that these results will provide the basis for new research projects in clinical practice that aim to rapidly assess colorectal cancer risk using microarray gene expression analysis.

Relationship between Plasma Triglyceride Level and Severity of Hypertriglyceridemic Pancreatitis

Background Hypertriglyceridemia is the third most common cause of acute pancreatitis, but whether the level of triglyceride (TG) is related to severity of pancreatitis is unclear. Aim To evaluate the effect of TG level on the severity of hypertriglyceridemic pancreatitis (HTGP). Design Retrospective cohort study. Methods We reviewed the records of 144 patients with HTGP from 1999 to 2013 at Tri-Service General Hospital. Patients with possible etiology of pancreatitis, such as gallstones, those consuming alcohol or drugs, or those with infections were excluded. The classification of severity of pancreatitis was based on the revised Atlanta classification. We allocated the patients into high-TG and low-TG groups based on the optimal cut-off value (2648 mg/dL), which was derived from the receiver operating characteristic (ROC) curve between TG level and severity of HTGP. We then compared the clinical characteristics, pancreatitis severity, and mortality rates of the groups. Results There were 66 patients in the low-TG group and 78 patients in the high-TG group. There was no significant difference in the age, sex ratio, body mass index, and comorbidity between the 2 groups. The high-TG group had significantly higher levels of glucose (P = 0.022), total cholesterol (P = 0.002), and blood urea nitrogen (P = 0.037), and lower levels of sodium (P = 0.003) and bicarbonate (P = 0.002) than the low-TG group. The incidences of local complication (P = 0.002) and severe and moderate form of pancreatitis (P = 0.004) were significantly higher in the high-TG group than in the low-TG group. The mortality rate was higher in the high-TG group than in the low-TG group (P = 0.07). Conclusions Higher TG level in patients with HTGP may be associated with adverse prognosis, but randomized and prospective studies are needed in the future verify this relationship.

The correlation between lipoprotein ratios and hearing outcome in idiopathic sudden sensorineural hearing loss patients

Recent reports have identified hypercholesterolaemia as a significant risk factor for idiopathic sudden sensorineural hearing loss (ISSNHL). Therefore, we investigated whether lipid profiles and lipoprotein ratios are correlated with the prognosis of hearing recovery in ISSNHL patients.

Albuminuria and neck circumference are determinate factors of successful accurate estimation of glomerular filtration rate in high cardiovascular risk patients.

Background Estimated glomerular filtration rate (eGFR) is used for diagnosis of chronic kidney disease (CKD). The eGFR models based on serum creatinine or cystatin C are used more in clinical practice. Albuminuria and neck circumference are associated with CKD and may have correlations with eGFR. Aim We explored the correlations and modelling formulates among various indicators such as serum creatinine, cystatin C, albuminuria, and neck circumference for eGFR. Design Cross-sectional study. Methods We reviewed the records of patients with high cardiovascular risk from 2010 to 2011 in Taiwan. 24-hour urine creatinine clearance was used as the standard. We utilized a decision tree to select for variables and adopted a stepwise regression method to generate five models. Model 1 was based on only serum creatinine and was adjusted for age and gender. Model 2 added serum cystatin C, models 3 and 4 added albuminuria and neck circumference, respectively. Model 5 simultaneously added both albuminuria and neck circumference. Results Total 177 patients were recruited in this study. In model 1, the bias was 2.01 and its precision was 14.04. In model 2, the bias was reduced to 1.86 with a precision of 13.48. The bias of model 3 was 1.49 with a precision of 12.89, and the bias for model 4 was 1.74 with a precision of 12.97. In model 5, the bias could be lower to 1.40 with a precision of 12.53. Conclusions In this study, the predicting ability of eGFR was improved after the addition of serum cystatin C compared to serum creatinine alone. The bias was more significantly reduced by the calculation of albuminuria. Furthermore, the model generated by combined albuminuria and neck circumference could provide the best eGFR predictions among these five eGFR models. Neck circumference can be investigated potentially in the further studies.

Vascular anatomy is a determining factor of successful submental flap raising: a retrospective study of 70 clinical cases

The vascular anatomy of submental flaps (SFs) represents a determining factor in successful SF raising. However, little attention has been focused on the venous return of SFs. Thus, the present study aimed to investigate SF venous return. This study enrolled patients who underwent SF reconstructive surgery in a tertiary referral center between November 2009 and October 2016. The drainage pathway of the SF venous return was routinely identified during the course of our operations to prevent damage during head and neck surgery. The venous return data of 70 patients were reviewed. The size of the flaps ranged from 15 to 84 cm2, and total flap loss was not observed in the case series. All of the submental arteries originated from the facial artery; however, the submental veins of 70 patients returned to either the internal jugular vein (IJV, 72.9%) or the external jugular vein (EJV, 27.1%). Our data suggest that drainage of the submental vein into the EJV, which has been previously overlooked, should receive greater attention during SF surgeries. The results support mandatory preservation of the EJV and IJV and indicate that vascular anatomy is a determining factor for successful SF raising.
