Question: In advanced gastric cancer (tumor stages T2-T4), associations with polymorphisms of the interleukin-1 (IL-1) gene cluster have been made. In early-stage gastric cancer, which we defined as adenocarcinoma confined to the mucosa or submucosa (stage T1), the role of host genetic susceptibility remains to be determined.', "Eighty-eight patients with early-stage gastric cancer (stage T1, 77 positive for Helicobacter pylori) and 145 controls were genotyped for polymorphisms in the IL-1 gene cluster and the tumor necrosis factor alpha (TNF-A) gene. Statistical analysis was performed using the chi2 test and the Fisher's exact test, respectively.", 'The homozygous genotype IL-1RN*2/2 of the IL-RN gene was strongly associated with early-stage gastric cancer (P < .0001), whereas further associations with the IL-1 gene cluster were not observed. A weak association of the TNF-A-308A allele with the diffuse type of early-stage gastric cancer, and an association with a composite of two or three proinflammatory polymorphisms, which predispose to increased production of the proinflammatory cytokines IL-1beta and TNF-alpha, could also be demonstrated.

Answer: Is allele 2 of the interleukin-1 receptor antagonist gene associated with early gastric cancer?

Question: To determine whether cancer antigen-125 (CA-125) levels are increased in women with endometriosis, especially in those with endometriomas (OMAs), deep infiltrating lesions (DIE), and superficial endometriosis (SUP) compared with controls without endometriosis in a large cohort of operated women.', 'Cross-sectional study (Canadian Task Force classification II-2).', 'Tertiary-care university hospital.', 'Four hundred six women with histologically proven endometriosis and 279 women without endometriosis.', 'Surgical examination of the abdomino-pelvic cavity.', 'Preoperative serum CA-125 antigen levels were evaluated by electrochemoluminescence immunoassay in women with endometriosis and controls. Correlations between serum CA-125 levels and clinical and anatomical characteristics of disease severity were examined. Women with endometriosis displayed higher mean serum CA-125 levels compared with disease-free controls (50.162.4 U/mL vs 22.525.2 U/mL; p.001). CA-125 levels were significantly increased in women with OMA (60.863.5 U/mL) and DIE (55.268.7 U/mL) compared with women with SUP (23.224.5 U/mL) and controls (22.525.2 U/mL). There was no difference in CA-125 levels between patients with SUP and controls and between patients with OMA and DIE. CA-125 serum levels were correlated with DIE severity: the mean number of DIE lesions and worst DIE lesion.

Answer: Is increased serum cancer antigen-125 a marker for severity of deep endometriosis?

Question: There is a robust comorbidity between mood disorders and cardiovascular disorder (CVD). The atherogenic index of plasma (AIP) and the atherogenic coefficient (AC) are important atherogenic indexes. The aims of this study were to delineate whether AIP and AC are increased in mood disorders especially when comorbid with tobacco use disorder (TUD).', 'In this case-control study we included 134 patients with mood disorders, bipolar disorder and unipolar depression (cases), and 197 individuals without mood disorder (controls) divided into those with and without TUD (defined as never-smokers). Total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDLc) and low-density lipoprotein cholesterol (LDLc) were measured. AIP and AC were computed as log (TG/HDLc) and non-HDLc/HDLc, respectively.', 'The AIP and AC indexes were significantly increased in patients with mood disorders versus controls, both in depression and bipolar disorder. Patients with mood disorder without TUD and patients with TUD without mood disorder showed higher AIP and AC values than never-smokers while those with comorbid mood disorders and TUD showed significantly higher AIP and AC levels than all other individuals. A large part of the variance in the AIC (26.4%) and AC (20.4%) was explained by mood disorders, TUD, male gender and body mass index.

Answer:
Are atherogenic index of plasma and atherogenic coefficient increased in major depression and bipolar disorder , especially when comorbid with tobacco use disorder?
