The advanced glycation end products (AGEs), which can be assessed through skin autofluorescence (SAF), have been linked to chronic kidney disease (CKD), diabetes mellitus (DM), and aging. However, it is unknown how frailty SAF levels are associated with cardiovascular (CVD). We enrolled 1,000 consecutive CVD patients who participated in phase II cardiac rehabilitation (CR) underwent assessment of between November 2015 September 2017 at Juntendo University Hospital. Of these, 48 were excluded...

Abstract Background and Aims Durvalumab plus tremelimumab (Dur/Tre) therapy is expected to have good therapeutic efficacy for patients with unresectable hepatocellular carcinoma (u‐HCC). We previously reported that the neutrophil‐to‐lymphocyte ratio (NLR) during atezolizumab bevacizumab in u‐HCC was a useful marker predicting response. Therefore, we investigated whether NLR Dur/Tre could predict treatment outcomes u‐HCC. Design The present study included 64 treated evaluated their initial...

Abstract Background Advanced glycation end products (AGEs) are associated with aging, diabetes mellitus (DM), and other chronic diseases. Recently, the accumulation of AGEs can be evaluated by skin autofluorescence (SAF). However, relationship between SAF levels exercise capacity in patients cardiovascular disease (CVD) remains unclear. This study aimed to investigate association tissue clinical characteristics, including capacity, CVD. Methods We enrolled 319 consecutive CVD aged ≥40 years...

Background/Aim: Radiotherapy-induced malfunction of pacemakers and cardiac defibrillators has been reported, corresponding guidelines have developed in various countries. Although several studies reported the effects radiotherapy patients with implantable left ventricular assist device (LVAD), its safety remains unclear. Herein, we report three cases stereotactic ablative (SABR) using CyberKnife for early-stage lung cancer LVAD. Case Report: Three their 50s or 60s, including two women one...

Cardiac rehabilitation (CR) is categorized as a class I recommendation in the guidelines for management of patients with cardiovascular disease (CVD). However, penetration rate outpatient CR low Japan. We designed pilot study to evaluate safety and feasibility tele-CR using remote biological signal monitoring system.

The frailty state consists of not only physical but also psycho-emotional problems, such as cognitive dysfunction and depression well social problems. However, few reports have examined the relationship between anxiety levels in elderly patients undergoing cardiac rehabilitation (CR).We analyzed 255 (mean age: 74.9 ± 5.8 years, 67% male) who participated early phase II CR at Juntendo University Hospital. At beginning CR, carried out self-assessments based on Kihon Checklist (KCL) State Trait...

Arterial stiffness contributes to the development of cardiovascular disease (CVD). However, relationship between arterial and exercise tolerance in CVD patients with preserved ejection fraction (pEF) those reduced EF (rEF) is unclear. We enrolled 358 who participated cardiac rehabilitation underwent cardiopulmonary testing at Juntendo University Hospital. After excluding 195 had undergone open heart surgery 20 mid-range EF, were divided into pEF (n = 99) rEF 44) groups. was assessed using...

Summary Although the shortened dental arch ( SDA ) concept has been known to all over world, acceptance of as an oral health standard can be questionable from patients' point view, even if it is biologically reasonable. Furthermore, because insurance system covers removable partial dentures RPD s) for citizens in Japan, patients seem prefer receive prosthetic treatment replace missing teeth. However, there were few field surveys investigate usage rate s Japan. The purpose this study was...

Peak oxygen uptake (peak VO2 ) and heart rate reserve (HRR) are independent prognostic markers of cardiovascular disease. However, the impact peak HRR on long-term prognosis after off-pump coronary artery bypass grafting (OP-CABG) remains unclear.To determine in patients OP-CABG.We enrolled 327 (mean age, 65.1 ± 9.3 years; male, 80%) who underwent OP-CABG participated early phase II cardiac rehabilitation.
