RESUMEN
BACKGROUND: Metabolic syndrome (MS) increases the risk of heart disease, stroke, and other complications. AIM: The aim of this study was to assess the clinical and biochemical parameters of MS and its complications (cerebrovascular accidents, cardiovascular accidents, DN or chronic kidney disease (CKD) compared with healthy controls especially among the younger population in Northern India. MATERIAL AND METHODS: A total of 245 (healthy, MS and it's complicated) aged 18-70 years participated in the Open-Label, Single Centered; hospital-based random selection case-control comparative study. All anthropometric and biochemical assessment was done after proper consent. The metabolic syndrome was determined by IDF criteria. RESULTS: The key risk parameters in three groups i.e. Control, Metabolic syndrome, and Complicated was TG (96.5⯱â¯46.9, 194.1⯱â¯87.8, 148.0⯱â¯102.2). LDL (91.2⯱â¯27.2, 114.0⯱â¯31.8, 69.1⯱â¯42.5, BP (120.1⯱â¯9.9, 139.3⯱â¯13.3, 132.1⯱â¯15.0) and high fasting glucose (81.1⯱â¯13.7, 164.5⯱â¯84.3, 138.0⯱â¯74.5). The hs-CRP is also significantly increased in the complicated group. The subanalysis of data also indicates that younger middle age (36-55 years) group both male and female is obese, hypertensive, diabetic with lipid abnormality according to IDF criteria. CONCLUSION: The risk factors like high TG, low HDL, high BP, and high fasting glucose were found higher particularly in younger population which may lead to diagnosis & complications of diabetes, hypertension and lipid abnormality. Due to changing physiology in young and middle age population these individuals are moving towards metabolic syndrome easily and needs frequent monitoring, preventive checkups, and lifestyle changes to prevent complications.

Metabolic syndrome (MetS) is an inflammatory disorder, in which various cytokines play important role in tilting balance towards disease state. Interleukin-10 (IL-10) is an important antiinflammatory cytokine, but its genetic polymorphisms and serum levels in Indian MetS subjects are unknown. Three IL-10 gene polymorphisms (-1082A>G (rs1800896), -819C>T (rs1800872) and -592C>A (rs1800871)) were genotyped with PCR-RFLP in MetS subjects (n = 384) and age/sex matched control subjects (n = 386). Serum IL-10 was measured using enzyme-linked immunosorbent assay. Serum IL-10 level was significantly low in MetS subject and significantly correlated with clinicobiochemical parameters of MetS. Of three investigated promoter polymorphisms, IL-10 -819C> T and -592C>A were significantly associated with risk of MetS. The mutant alleles -819T and -592A of IL-10 gene polymorphism were significantly higher in MetS subjects compared to controls. Of the four different haplotypes obtained, common ACC haplotype and rare GTA haplotype of IL-10 polymorphisms were associated with MetS. The mean of fasting insulin and HOMA-IR were significantly different between the genotypes of both -819 C>T and -592C>A polymorphisms of IL-10 in MetS subjects. These results suggested that polymorphisms in IL-10 gene (-819C>T and -592C>A), haplotypes (ACC and GTA) and serum level are significantly associated with risk of MetS. IL- 10 -819C>T and -592C>A polymorphic variants are also significantly associated with insulin level and homeostasis model assessment-insulin resistance in north Indian MetS subjects.

INTRODUCTION: Oral cancer accounts for approximately 2.1% of all cancers worldwide. In India, oral squamous cell carcinoma (OSCC) is the most common cancer with half a million new cases diagnosed every year. More than 50% of patients eventually develop local recurrence or metastasis usually within the first 2-years following completion of treatment. It is beneficial to analyze the prognostic significance of Cyclin D1, p53 and EGFR which are critical mediators in the pathogenesis of OSCC. The objective of this study was to assess the association of expression of these markers with recurrence and pattern of recurrence in OSCC patients undergoing chemoradiation. MATERIALS AND METHODS: A Total 290 OSCC cases of locally advanced stage (III, IV) oral cancer with World Health Organization (W.H.O.) performance status of grade 0/1 in the year 2009-2012 were enrolled in the study. Treatment response was assessed according to W.H.O. criteria. Cyclin D1, EGFR and p53 expression in tumor tissue was estimated by immunohistochemical (IHC) method and quantified as percentage positive nuclei. RESULTS: During the 2-years follow up, 56 (19.3%) patients recurred, out of which, 47 (83.9%) were locoregional and 9 (16.1%) distant sites. On correlating, χ2 test showed significant (P < 0.05 or P < 0.01 or P < 0.001) association of marker expressions (Cyclin D1, EGFR and p53) with recurrence. The strong positive expressions of all three markers showed significant association with early time of recurrence. The multivariate logistic regression analysis showed significant (P < 0.05 or P < 0.01 or P < 0.001) association of recurrence with primary site, differentiation, Cyclin D1 and p53 expressions indicating these as an independent predictors of recurrence in OSCC. The Cyclin D1, EGFR and p53 expressions also showed significant (P < 0.001) poor survivals (OS, DFS and RFS) in patients with positive/strong positive expressions than negative expression suggesting their prognosis in OSCC. CONCLUSION: Our results signifies that tumors over expressing Cyclin D1, EGFR and p53 are resistant to chemoradiation and are associated with increased risk of locoregional recurrence and metastasis in OSCC patients undergoing chemoradiation.
RESUMEN
INTRODUCTION: Cyclin-D1, p53 and EGFR are molecular markers that regulate the cell cycle and play an important role in tumor progression and development. The present study evaluates the prognostic significance of these markers with chemoradiation response in patients of locally advanced oral squamous cell carcinoma (OSCC). MATERIAL AND METHOD: A total of 97 OSCC patients (females = 19 and males = 78), aged 20-67 years and stage III/IV were recruited. Treatment response was assessed according to WHO criteria. Cyclin-D1, p53 and EGFR expressions in tumor tissue was estimated by immunohistochemical (IHC) method and quantified as percentage positive nuclei. RESULTS: The positive expression rates of molecular markers were 86.6% for Cyclin-D1, 92.8% for EGFR and 85.6% for p53. The strong positive expressions of both Cyclin-D1 and p53 showed significant association with poor response. The Cox multivariate regression analysis showed coexpressions of Cyclin-D1 and p53 a significant and independent predictor of overall survival (OR = 1.90, 95% CI = 1.45-4.82, p = 0.046) after adjusting the demographic, clinicopathological and radiological response. The strong positive expressions of Cyclin-D1 and p53 and coexpressions of Cyclin-D1, EGFR and p53 showed significant (p < 0.05 or p < 0.01 or p < 0.001) and lower survival as compared to negative or moderate positive expressions and coexpressions, respectively. CONCLUSION: Expressions and coexpressions of Cyclin-D1 and p53 may serve as a prognostic marker in OSCC patients.
RESUMEN
EGFR and p53 are molecular markers which play important role in tumor progression and development. The objective of this study was to assess the association between EGFR and p53 expression and survival, and to determine whether EGFR and p53 expression levels were associated with differences quality of life in OSCC patients undergoing chemoradiation. A total of 120 OSCC patients aged 20-67 y and stage III/IV were recruited. Treatment response was assessed according to W.H.O. (1979). EGFR and p53 expression in tumor tissue was estimated by immunohistochemical (IHC) method and quantified as percentage positive nuclei. Molecular marker expressions of both EGFR and p53 were found significantly (P < 0.01 or P < 0.001) associated with overall response, survivals and quality of life. Neither EGFR nor p53 expression was associated with hematologic or non-hematologic toxicity. EGFR and p53 molecular marker expressions may have significant association with survival and QOL in OSCC patients undergoing chemoradiation.

This study compared the efficacy and toxicity of Gefitinib, Methotrexate and Methotrexate plus 5-Fluorouracil (5-FU) in patients of recurrent squamous cell carcinoma of head and neck (SCCHN) treated with palliative intent. Patients with recurrent SCCHN not amenable to curative treatment were randomly assigned to Gefitinib, Methotrexate or Methotrexate plus 5-FU arm. The primary end point was overall survival. Secondary end points of interest were objective response rate, toxicity and quality of life. Total 117 patients were analyzed. Median overall survival and objective response rates were 8.8 months, 7.8 months and 8.1 months and 7.7%, 5.0% and 7.9% in Gefitinib, Methotrexate and Methotrexate plus 5-FU arms respectively with no statistically significant difference between 3 arms. Gefitinib had different toxicity profile compared with other arms. Majority of toxicities were Grade 1 or Grade 2. Gefitinib had significant improvement in quality of life during initial months over Methotrexate. There was no suggestion that Gefitinib significantly prolonged overall survival compared with Methotrexate and Methotrexate plus 5-FU. However, improved Quality of Life with manageable toxicities was observed.

Adipose tissue secretes various kinds of adipokines that controls the glucose and lipid metabolism in humans. The abdominal visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) both are associated with metabolic syndrome and insulin resistance. IL-6 is one of the adipokines, which promotes insulin resistance and dyslipidemia in humans. The association of adipokines with metabolic syndrome at protein levels are well documented. However, their association at gene expression level are lacking. The present study was design to investigate IL-6 mRNA expression in adipose tissues (VAT and SAT) and its correlation with metabolic risk factors and insulin resistance (HOMA) in post menopausal women. A total of 108 Asian North Indian post menopausal women, 54 without metabolic syndrome (controls) and 54 with metabolic syndrome (cases) were recruited and evaluated. Overnight fasting blood samples were collected at admission and abdominal visceral and subcutaneous adipose tissues were collected during open abdomen surgery. The results showed significantly (p < 0.05 or p < 0.01 or p < 0.001) higher mean SBP, glucose, insulin, HOMA, TG, VLDL and serum IL-6 while significantly (p < 0.001) lower HDL and estrogen in cases as compared to controls. In cases, the relative mean SAT IL-6 expression was also significantly (p < 0.05) higher as compared to VAT. Further, in cases, the VAT IL-6 expression showed significant (p < 0.05 or p < 0.001) and negative correlation with WC, WHR, glucose, HOMA, TC, LDL and estrogen while SAT IL-6 expression also showed significant (p < 0.05 or p < 0.01 or p < 0.001) and negative correlation with WC, WHR and estrogen. The Cox regression analysis found VAT IL-6 mRNA expression the significant (p < 0.05 or p < 0.01) an independent predictor of WC, HOMA, TC, LDL and estrogen while SAT IL-6 mRNA expression the significant (p < 0.01) an independent predictor of TG and VLDL. The study concluded that IL-6 expressions of both visceral and subcutaneous tissues may be associated with metabolic risk factors in postmenopausal Asian North Indian women.
