Recently, the association between gastric cancer risk and a functional polymorphism of Toll-like receptor 2 (TLR2), -196 to -174del, was reported for a Japanese population. This study aimed to confirm the associations of the polymorphism with the risk of gastric cancer, as well as Helicobacter pylori seropositivity and the risk of gastric atrophy in Japanese. The study subjects were 583 histologically diagnosed gastric cancer patients and 1636 age- and sex-frequencymatched control outpatients who visited Aichi Cancer Center Hospital from the years 2001 to 2005. Serum anti-H. pylori IgG antibody and pepsinogens were measured to evaluate H. pylori infection and gastric atrophy, respectively. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by a logistic model. The age- and sex-adjusted ORs of gastric cancer were 1.13 (95% CI: 0.88-1.46) for ins/del, 1.17 (95% CI: 0.79-1.73) for del/del, and 1.14 (95% CI: 0.89-1.45) for ins/del + del/del, relative to the ins/ins genotype compared with gastric atrophy controls; none of these findings were statistically significant. The TLR2 -196 to 174del polymorphism was not significantly associated with either H. pylori seropositivity or gastric atrophy. Our study did not reproduce the association between gastric cancer risk and the TLR2 -196 to -174del polymorphism in Japanese. Further examinations with sufficient numbers of study subjects are required to verify our findings.

Difficult removal of totally implantable venous access devices in adult patients: Incidence, risk factors, and management

Shohei Chatani, Ryota Tsukii, Kyohei Nagasawa, Takaaki Hasegawa, Shinichi Murata, Mina Kato, Hidekazu Yamaura, Hiroaki Onaya, Keitaro Matsuo, Yoshiyuki Watanabe, Yoshitaka Inaba

Summary: This study investigated the difficulty in removing totally implantable venous access devices (TIVADs) and identified associated risk factors. Interventional radiology (IR) approaches for difficult removal were also explored. The results showed that indwelling duration and subcutaneous leakage of fluid were significant risk factors for difficult removal. IR techniques were found to be minimally invasive and useful in some cases.

Summary: This study analyzed the relationship between cigarette smoking, alcohol consumption, and head and neck cancer risk factors in less developed and more developed countries. The results showed that the duration of smoking and alcohol consumption had different effects on the risk of specific cancer sites depending on the country's level of development. These findings suggest that the degree of industrialization and economic development affects the relationship between smoking, alcohol, and head and neck cancer.

Summary: This study conducted a Mendelian randomization analysis to assess the causal association between genetically predicted glycemic traits and the risk of primary open-angle glaucoma (POAG). The results did not provide strong evidence to support the association between genetically predicted glycemic traits and POAG in the Japanese population.

Summary: The purpose of this study was to explore the impact of ablative margin depicted by CT immediately after RF ablation on reducing LTP for CRC lung metastases. A retrospective study was conducted on 70 patients who underwent RF ablation for CRC lung metastases. The results indicated that an ablative margin of at least 2 mm is important to reduce LTP after RF ablation for CRC lung metastases.

Summary: This study investigates the association between HbA1c and blood glucose levels and their corresponding genetic loci in a non-diabetic Japanese population. The study identifies KCNQ1 and TMC6 loci as being associated with HbA1c levels, but no replication is found for the loci associated with blood glucose levels. Furthermore, the variant rs2299620 in KCNQ1 shows heterogeneity in its effect on HbA1c levels based on BMI grouping.

Summary: The association between kidney function and cancer incidence is inconsistent among previous reports, and data on the Japanese population are lacking. This study aimed to evaluate the association of estimated glomerular filtration rate (eGFR) with cancer incidence and mortality in a Japanese cohort. The findings suggest a U-shaped relationship between eGFR and cancer incidence, with both moderate low and high eGFRs associated with higher cancer incidence. Only high eGFR was associated with cancer mortality, and kidney dysfunction enhanced the cancer risk from smoking.

Summary: The study evaluated the population-based impact of smoking, drinking, and genetic factors on low HDL-C levels using data from the J-MICC Study. The findings showed that smoking, drinking, and certain genetic variants were associated with HDL-C levels, but there was no significant gene-environment interaction. The population-based impact of the genetic factor CETP rs3764261 was higher than that of smoking and lower than that of drinking.

Summary: In Japanese adults, stress-coping strategies are related to all-cause mortality. Three coping strategies (emotional expression, emotional support-seeking, and disengagement) were associated with lower mortality in women. Emotional expression, problem-solving, and positive reappraisal were associated with lower mortality in men, but the relationship depended on the follow-up period. There was evidence of sex differences in the relationship between emotional support-seeking and all-cause mortality.

Summary: The introduction of rituximab has led to a decline in mortality rates of non-Hodgkin lymphoma in both Japan and the United States, despite an increase in incidence. However, the trends in mortality rates have differed between the two countries, with the mortality rate declining continuously in the United States but stopping in Japan.

Mediation analysis unveils a carcinogenic effect of ADH1B rs1229984 through mechanisms other than change in drinking intensity: oesophageal cancer case-control study

Summary: Alcohol is metabolized to acetaldehyde and acetate through the actions of alcohol dehydrogenase and aldehyde dehydrogenase. The ADH1B rs1229984 polymorphism is associated with drinking habits and the risk of esophageal cancer. Mediation analysis showed that this genetic variant increases the risk of esophageal cancer by affecting alcohol metabolism and drinking intensity.

Summary: This Japanese cohort study examined the association between awareness of limiting food intake and all-cause mortality risk. The results showed that women with awareness of limiting fat intake had a significantly lower mortality risk, while awareness of limiting energy or sweets intake was not related to mortality risk reduction.
