Resistance to Preoperative Oral Care Is Associated With Postoperative Pneumonia After Oesophageal Cancer Surgery.

Background/aim: Postoperative pneumonia is a serious complication of major oesophageal surgery. We aimed to clarify the association between the degree of improvement in oral hygiene by perioperative oral care and postoperative pneumonia in oesophageal cancer patients.

Patients And Methods: Oesophageal cancer patients (n=129) who underwent esophagectomy received perioperative oral care.

The suppression of IL-17 production from T cells by gallate-type procyanidin is mediated by selectively inhibiting cytokine production from dendritic cells.

Abnormal T helper 17 (Th17) responses promote inflammation and cause inflammatory diseases. Natural components that modulate Th17 functions can be effective for the amelioration of inflammatory diseases. Procyanidin B2 3,3''-di-O-gallate (PCB2DG) contained in grape seeds markedly suppressed interleukin (IL)-17 production from spleen cells but not CD4 T cells.

Predictive factors for dental inflammation with exacerbation during cancer therapy with FDG-PET/CT imaging.

Purpose: Oral adverse events, such as dental inflammation with exacerbation, are stressful and lead to poor nutrition in patients undergoing cancer therapy. Thus, the prediction of risk factors for dental inflammation with exacerbation is important before cancer therapy is initiated. We hypothesized that, during cancer therapy (DIECT), fluorodeoxyglucose-positron emission tomography/computed tomography (FDG-PET/CT) imaging could be useful to predict dental inflammation with exacerbation.

Procyanidin B2 gallate regulates TNF-α production from T cells through inhibiting glycolytic activity via mTOR-HIF-1 pathway.

Procyanidins are polyphenols with antioxidant, anti-obesity, and anti-inflammatory properties. Procyanidin B2 (PCB2) gallate; specifically, PCB2 3,3″-di-O-gallate (PCB2DG), inhibits cytokine production in T cells. However, the molecular interactions and partners of PCB2DG underlying this suppression of cytokine production are unclear.

MicroRNA 16-5p is upregulated in calorie-restricted mice and modulates inflammatory cytokines of macrophages.

Caloric restriction (CR) has long been known to increase median and maximal lifespans and to decrease mortality and morbidity in short-lived animal models, likely by altering fundamental biological processes that regulate aging and longevity. However, the detailed mechanisms of immunomodulation by CR remain unclear. In this study, we established a mouse model for CR and analyzed the changes of immune cells in these mice.

Validity of using multi-frequency bioelectrical impedance analysis to measure skeletal muscle mass in preschool children.

[Purposes] Although it is recommended to develop a habit of physical activities, there is no easy way to measure skeletal muscle mass in preschool children, which cause the difficulty of evaluation. The purpose of this study was to examine the validity of body composition including the skeletal muscle mass assessment using multi-frequency bioelectrical impedance analysis by comparing body fat mass obtained by using multi-frequency bioelectrical impedance analysis method and body mass index formulas. [Subjects and Methods] Ninety-four children were surveyed for age, height, weight, grip strength, maximum occlusal force, thickness of muscle and fat mass (masseter and lower limb), body fat mass, skeletal muscle mass, and calf circumference.
