Communication Skills and Illness Perception Among Non-Japanese-Speaking Patients in Japan.

Background: Non-Japanese-speaking patients taking medical treatment in Japan face language barriers and lack of language assistance. Language barriers influence all processes from preventive services to treatment, and insufficient communication can affect patient outcomes. Illness perception, which is related to illness-coping behaviors and self-care behaviors, is an important factor for effective treatment, but no studies have investigated the relationship between communication skills and illness perception among non-Japanese-speaking patients.

Intravenous branched-chain amino acid administration for the acute treatment of hepatic encephalopathy: a systematic review and meta-analysis.

Background: Hepatic encephalopathy (HE) is a severe complication of acute hepatic failure requiring urgent critical care management. Branched-chain amino acids (BCAAs) such as leucine, isoleucine, and valine have been investigated as potential treatments to improve outcomes in patients with acute HE. However, the effectiveness of BCAA administration during the acute phase remains unclear.

Effectiveness of 4-dimensional maximum intensity projection (4D-MIP) for respiratory motion management with uncertain interobserver delineation.

This study was conducted to evaluate the use of 4-dimensional (4D) maximum intensity projection (4D-MIP) to compensate for the disadvantages of average intensity projection (AIP), which is used to determine the internal target volume (ITV) in lung tumors. A respiratory motion phantom with a simulated tumor was imaged using 4D computed tomography (4D-CT). AIP and 4D-MIP were generated based on 10 phases of 4D-CT, followed by contouring of the ITV and ITV; these were compared with the ITV contoured in 10 phases of 4D-CT (ITV).

History of Lens Care Products in Japan: Insights From Advertisements in the Journal of the Japan Contact Lens Society for 65 Years.

This review examines the history of contact lens (CL) care products, particularly focusing on hard contact lenses (HCLs) like those made from polymethyl methacrylate and rigid gas permeable (RGP) materials. Although literature on CL history is extensive, there is limited information on the history of CL care products, especially in Japan. This review uses advertisements from the Journal of the Japan Contact Lens Society from 1959 to 2023 to trace the evolution of these products.

α-Cyclodextrin supplementation improves endurance exercise performance and reduces post-exercise fatigue in human males: a randomized, double-blind, placebo-controlled, parallel-group study.

α-Cyclodextrin (αCD), a cyclic hexasaccharide composed of six glucose units, is not digested in the small intestine but is completely fermented by gut microbes. Recently, we have reported that αCD supplementation for nonathlete men improved their 10 km biking times. However, the beneficial effects of αCD on exercise are not yet fully understood.

Real-world antithrombotic strategies in patients with atrial fibrillation and recently developed acute coronary syndrome.

Background: The antithrombotic strategy for patients with atrial fibrillation (AF) and coronary artery disease following percutaneous coronary intervention is shifting towards less intensive. Nevertheless, for patients with AF and acute coronary syndrome (ACS), an optimal antithrombotic strategy is yet to be established.

Methods And Results: We conducted a multi-center cohort study involving 146 Japanese centers that had prospectively registered 460 patients with AF and ACS followed for 2 years.

Cytokine dynamics and quality of life: unraveling the impact of cell-free and concentrated ascites reinfusion therapy in ovarian cancer patients.

Background: The quality of life (QOL) of ovarian cancer patients is often impaired by refractory ascites. Cell-free and concentrated ascites reinfusion therapy (CART) is a palliative treatment for refractory ascites, but adverse events, such as fever, are problematic. Several cytokines have been suggested to be responsible for the adverse events, but they have not been investigated in detail.

Impact of adjuvant trastuzumab therapy and its discontinuation on cardiac function and mortality in patients with early-stage breast cancer: An analysis based on the Japanese Receipt Claim Database.

Standard trastuzumab therapy can reduce the risk of early recurrence of HER2-positive breast cancer. However, trastuzumab-induced cardiac dysfunction may force the discontinuation of adjuvant trastuzumab therapy. Incidentally, there are still unclear whether or not trastuzumab treatment should be continued in the setting of reduced cardiac function.

Recent advances in biomarkers for senescence: Bridging basic research to clinic.

In this review, we review the current status of biomarkers for aging and possible perspectives on anti-aging or rejuvenation from the standpoint of biomarkers. Aging is observed in all cells and organs, and we focused on research into senescence in the skin, musculoskeletal system, immune system, and cardiovascular system. Commonly used biomarkers include SA-βgal, cell-cycle markers, senescence-associated secretory phenotype (SASP) factors, damage-associated molecular patterns (DAMPs), and DNA-damage-related markers.

Impact of correlation structure on sample size requirements of statistical methods for multiple binary outcomes: A simulation study.

Background: In randomized clinical trials, multiple-testing procedures, composite endpoints, and prioritized outcome approaches are increasingly used to analyze multiple binary outcomes. Previous studies have shown that correlations between outcomes influence their sample size requirements. Although sample size is an important factor affecting the choice of statistical methods, the power and required sample sizes of methods for analyzing multiple binary outcomes have yet to be compared under the influence of outcome correlations.
