Association of body mass index with all-cause mortality in patients with diabetes: a systemic review and meta-analysis.

Background: The obesity paradox phenomenon has been found in different populations, such as heart failure and coronary heart disease, which suggest that patients with established cardiovascular disease (CVD) and with normal weight had higher risk of mortality than those with overweight or obesity. However, the obesity paradox is controversial among patients with diabetes which has been considered as the coronary heart disease equivalent. The aim of our study was to summarize current findings on the relationship between body mass index (BMI) and all-cause mortality in patients with diabetes and make a meta-analysis.

Association of salivary alpha 2-macroglobulin levels and clinical characteristics in type 2 diabetes.

Aims/introduction: Studies suggest that salivary proteins can be used as potential non-invasive markers for clinical diagnosis and screening for diabetes. Previous reports showed that plasma alpha 2-macroglobulin (A2MG) levels were higher in diabetic patients, especially with diabetic complications. We investigated the relationship between salivary A2MG values and clinical characteristics in patients with type 2 diabetes.

Association Between a Glucokinase Regulator Genetic Variant and Metabolic Syndrome in Taiwanese Adolescents.

Aims: Variants of the glucokinase regulator (GCKR) gene are associated with metabolic syndrome (MetS). The present study explored the association between a common variant of this gene and MetS and its related traits in Taiwanese adolescents.

Methods: The frequency of MetS and its features were compared between subjects (n = 962; 468 male, 494 female) with different genotypes or alleles of the GCKR rs780094 single-nucleotide polymorphism.

Association of complete blood cell counts with metabolic syndrome in an elderly population.

Background: Metabolic syndrome's (MetS) role in predicting cardiovascular diseases and diabetes has been confirmed in many large cohort studies. Nontraditionally, hematogram components are significantly related to MetS in many different age groups. However, little is known about its role among the elderly.

The relationships between hematogram and metabolic syndrome in elderly subgroups: A Taiwan cohort study.

Background: Abnormal hematogram components could predict future metabolic syndrome (MetS) and diabetes. However, there was no study focusing on the subgroups of the elderly. In this ten-year longitudinal study, we investigated the association between hematogram components, future MetS and diabetes in the elderly.

Smoking and drinking can induce p15 methylation in the upper aerodigestive tract of healthy individuals and patients with head and neck squamous cell carcinoma.

Background: The consumption of tobacco and alcohol has been implicated in the development of head and neck squamous cell carcinoma (HNSCC). Promoter methylation of tumor suppressor genes is common in HNSCC. In this study, the authors evaluated the effects of tobacco and alcohol on p15 gene methylation of cells in cells from the mouth and throat of physically healthy individuals and patients with HNSCC.

Evaluation of hypermethylated tumor suppressor genes as tumor markers in mouth and throat rinsing fluid, nasopharyngeal swab and peripheral blood of nasopharygeal carcinoma patient.

The purpose of our study was to evaluate the frequency of hypermethylated tumor suppressor genes (TSGs) in peripheral blood, mouth and throat (M&T) rinsing fluid and nasopharyngeal (NP) swabs of nasopharyngeal carcinoma (NPC) patients. Six normal NP tissues, 43 M&T rinsing fluid, 37 NP swabs and 43 peripheral blood from healthy non-smokers and non-drinkers without a family history of NPC, and 30 NPC tumors and their matched body fluid were analyzed for the presence of hypermethylated p15, p16, Ras association domain family 1 (RASSF1A), E-cadherin, and death-associated protein kinase (DAPK) by methylation-specific PCR. Sequencing analysis was carried out on selected NPC tumors and body fluid samples.

Detection of hypermethylated RIZ1 gene in primary tumor, mouth, and throat rinsing fluid, nasopharyngeal swab, and peripheral blood of nasopharyngeal carcinoma patient.

Purpose: The aims of this study are to examine the methylation status of the Fn2 RIZ1 gene in nasopharyngeal (NP) tumors and nasopharyngeal carcinoma (NPC) cell lines and to evaluate the clinical value of methylated RIZ1 gene in body fluid samples of NPC patients.

Experimental Design: Methylation status of RIZ1 was evaluated by MSP on CNE-2 and M1 cell lines, 30 tumor biopsies, and their matched body fluid samples, including mouth and throat (M & T) rinsing fluid, NP swabs, plasma, and buffy coat. Normal controls included 8 normal NP biopsies and body fluid samples from 29 healthy volunteers.

Loss of E-cadherin expression resulting from promoter hypermethylation in oral tongue carcinoma and its prognostic significance.

Background: E-cadherin is expressed on the surface of normal epithelial cells. Loss of E-cadherin expression has been found in cancers and is postulated to facilitate tumor cell dissociation and metastasis. This study evaluated the role of promoter dense methylation in the downregulation of E-cadherin expression in oral tongue carcinoma.

High frequency of promoter hypermethylation of the death-associated protein-kinase gene in nasopharyngeal carcinoma and its detection in the peripheral blood of patients.

Purpose: Death-associated protein (DAP)-kinase gene is frequently inactivated by promoter hypermethylation in cancer. The aim of this study was to evaluate the promoter methylation status of the DAP-kinase gene in nasopharyngeal carcinoma (NPC).

Experimental Design: The methylation status was evaluated by methylation-specific PCR (MSP).
