Key Points• PD-L1 expression is associated with poor prognosis in DLBCL.• The double-staining technique is a useful method for identifying and distinguishing PD-L1 1 DLBCL.Programmed cell death ligand 1 (PD-L1) is expressed on both select diffuse large B-cell lymphoma (DLBCL) tumor cells and on tumor-infiltrating nonmalignant cells. The programmed cell death 1 (PD-1)/PD-L1 pathway inhibits host antitumor responses; however, little is known about how this pathway functions in the tumor microenvironment. The aim of this study was to determine the clinicopathological impact of PD-L1 1 DLBCL. (P 5 .0323). This is the first report describing the clinicopathological features and outcomes of PD-L1

We identified a novel genetic variant associated with regular leisure-time exercise behavior. Further functional studies are required to validate the role of these variants in exercise behavior.

BackgroundA considerable interest has been drawn to potential protective effects of bilirubin against oxidative stress-related diseases. Smoking is known to be associated with lower concentrations of serum bilirubin, but other behavioral correlates of serum bilirubin have not been well studied. In this cross-sectional study, we examined the associations of behavioral and clinical factors with serum total bilirubin in Japanese men and women.MethodThe study subjects comprised of 4802 men and 6414 women aged 49–76 years who participated in the baseline survey of an ongoing cohort study on lifestyle-related diseases in Fukuoka, Japan. With consideration to time of the day of blood sampling and fasting hours, the associations with smoking, alcohol intake, body mass index, physical activity, coffee, tea, blood pressure, glycated hemoglobin (HbA1c), HDL cholesterol and non-HDL cholesterol with serum bilirubin were evaluated by analysis of covariance and multiple linear regression analysis.ResultsWhile smoking was negatively associated with serum bilirubin, alcohol consumption was positively associated with serum bilirubin in both men and women. Coffee consumption was associated with lower bilirubin concentrations in both sexes. In the multiple linear regression analysis, HDL cholesterol was positively and HbA1c was negatively associated with bilirubin in both men and women, and the associations were more evident in women.ConclusionSmoking, alcohol use and coffee consumption were important behavioral correlates of serum bilirubin in Japanese men and women. Serum HDL cholesterol was a measurable clinical correlate of bilirubin in women.

BackgroundAlthough beneficial associations have been reported between moderate alcohol intake and the serum lipid profile, it is unclear whether polymorphisms in alcohol-metabolizing enzymes can modify these associations. Here, we assessed the effects of ADH1B His48Arg (rs1229984), ALDH2 Glu504Lys (rs671), and their combination on these associations. Furthermore, we examined if the findings for ALDH2 could be replicated.MethodsWe categorized 889 male participants in the Japan Multi-Institutional Collaborative Cohort (J-MICC) Study into two groups based on presence or absence of minor allele(s) or four groups based on genotype combinations. We performed regression analyses of serum lipid concentrations on alcohol intake, with multivariable adjustment. The replication study was conducted among 2,562 men in the Shizuoka part of the J-MICC Study.ResultsThe ALDH2 Glu/Lys or Lys/Lys groups showed significant decreases in serum low-density lipoprotein (LDL) cholesterol with increasing alcohol consumption; the coefficient per intake increase of 10 g/day was −2.49 mg/dL (95% confidence interval [CI], −3.85 to −1.13), and a significant interaction with the polymorphism was confirmed (P for interaction = 0.006). This inverse correlation was more evident among the ADH1B His/His + ALDH2 Glu/Lys or Lys/Lys groups (−3.24 mg/dL, 95% CI, −5.03 to −1.45). Serum triglycerides were positively associated with alcohol consumption in the ADH1B His/His group (P for interaction = 0.020). The stronger association between serum LDL cholesterol and alcohol consumption in the ALDH2 Glu/Lys or Lys/Lys groups was replicated.ConclusionsThe ALDH2 Glu504Lys polymorphism can modify the association between alcohol intake and serum LDL cholesterol in Japanese men.

Background. Metabolic syndrome (MetS) and obesity are known risk factors for gastroesophageal reflux disease (GERD), which is often found in patients with endocrine disorders, such as thyroid dysfunction and hypopituitarism. To clarify the relationship of endocrine disease with GERD, we investigated the symptoms of GERD in patients with various endocrine diseases. Methods. Patients with various endocrine disorders who visited Kyushu University Hospital were included. GERD symptoms were examined using a self-administered questionnaire, the frequency scale for the symptoms of GERD (FSSG). Metabolic parameters, including body-mass index (BMI), waist circumference, blood pressure, hemoglobin A1c, total cholesterol, high-density lipoprotein cholesterol (HDL-C), and triglycerides, and values of endocrine function, including thyroid stimulating hormone, free thyroxin, cortisol, and insulin-like growth factor-1, were assessed. Results. A total of 111 consecutive patients were recruited for the study. Among these, 18 (16.2%) patients were considered to have GERD. Among the parameters, BMI (P = 0.03) and triglycerides (P = 0.001) showed a positive association and HDL-C (P = 0.0007) showed an inverse association with the FSSG score. However, none of the endocrine values were associated with the FSSG score. Conclusion. Symptoms of GERD in patients with endocrine disorders might be attributed to MetS as comorbidity.

Five-year mHAQ improved in early RA patients in the NinJa database. In daily clinical management of RA, likewise in clinical trials, early administration of MTX or biologic agents is able to improve physical function outcome.

We report a 29-year-old woman with a 2.5 year history of mixed connective tissue disease (MCTD) who developed idiopathic portal hypertension (IPH) and thrombocytopenia as a result of hypersplenism. She had recurrent esophagogastric variceal rupture. Hematological examination also revealed low levels of protein C activity. The liver biopsy specimen showed non-specific mild inflammation and no thrombi. However, portal vein thrombosis developed after splenectomy. This was a rare case of severe complications of IPH accompanying MCTD and protein C deficiency.
