ObjectivesThe aim of this study was to investigate the determinants of serum total homocysteine level (tHcy) in patients with type 2 diabetes mellitus (DM) according to sex.MethodsA total of 1,276 Japanese, diabetics (nxa0=xa0280) with a control group of non-diabetics (nxa0=xa0996), were enrolled into the study from 2003 to 2005. This cross-sectional study was conducted for all the subjects, using personal data regarding clinical characteristics and lifestyle. Multiple regression analysis was performed to analyze the association of tHcy with selected factors.ResultsIn diabetic subjects, estimated glomerular filtration rate (eGFR) and serum creatinine levels (Cre), even those within the normal range, were strongly associated with tHcy after adjustment in both sexes; the standardized partial regression coefficient of eGFR for tHcy was −0.251, (pxa0=xa00.001) in diabetic men and −0.523, (pxa0<xa00.001) in diabetic women. Furthermore, the eGFR of the diabetics, except patients with nephropathy, also had significant association with tHcy in both sexes. Fasting plasma glucose levels and serum triglyceride levels were strongly associated with tHcy in diabetic men only. HbA1c was also associated with tHcy in diabetic men only, though not as significantly. Age and presence of hypertension were significantly associated with tHcy in women.ConclusionsThis study suggests that there are some differences in the factors associated with tHcy between diabetics and non-diabetics, and between the sexes. There is, therefore, circumstantial evidence that elevated tHcy should be evaluated clinically. Because tHcy was strongly associated with eGFR and Cre, even within the normal ranges, tHcy may have important implications regarding the microangiopathy of the kidney and atherosclerosis.

ObjectiveTo investigate the personal features associated with dropout from regular outpatient care among persons with type 2 diabetes mellitus (DM).MethodsA total of 160 DM patients were enrolled in the study. As a retrospective analysis, outpatient’s clinical characteristics, lifestyle, or social features were gathered from their medical records or interview sheets. All the subjects were divided into two groups by adherence to diabetic care, namely, ‘dropout case’ (DC), or ‘ongoing case’ (OC), and were subjected to comparative analysis. We called the patients who did not receive outpatient treatment from the clinic on a regular basis, including treatment from other clinics or dropout of diabetic care, as DC. In contrast, patients who regularly visited the clinic were defined as OC. An unconditional multiple logistic regression analysis was performed to analyze the association of a dherence to diabetic care with several personal features.ResultsSixty-eight of 160 subjects (42.5%) were recognized as DC. The remaining 92 subjects (57.5%) were considered as OC. Young age (p=0.045), low plasma glucose (p=0.005) and hemoglobin A1c (HbA1c) levels (p=0.005), nonmedication (p<0.001) and no past history of DM (p=0.007) at the initial visit were the features related to dropout by crude analysis. Even after adjustment for age and gender by multivariate analysis, there remained significant inverse associations of dropout with HbA1c level, medical treatment (oral agents or insulin) and previous DM history. Neither occupation, distance from residence to clinic, smoking habit nor drinking habit was associated with dropout. Dropout mostly occurred after the initial or second visit.ConclusionsA mild condition of DM may be related to dropout from regular outpatient care. It may be necessary to clearly show the objectives and importance of regular visit to an outpatient clinic for diabetic care, particularly for screened mild DM cases in public health activities.

Exercise training has become part of the standard care for patients with cardiovascular disease. We investigated the effects of exercise training on exercise capacity, cardiac function, BMI, and quality of life in patients with atrial fibrillation (AF). We searched for randomized-controlled trials of supervised exercise training versus care without exercise training (the control) in patients with permanent or nonpermanent AF published up to November 2016. Standard mean differences (SMD) or mean differences (MD), and 95% confidence intervals (CIs) were calculated using random-effect models. We identified 259 trials, and after an assessment of relevance, five trials with a combined total of 379 participants were analyzed. In AF patients, exercise training significantly improved exercise capacity and left ventricular ejection fraction compared with the control (SMD: 0.91, 95% CI: 0.70 to 1.12; MD: 4.8%, 95% CIs: 1.56 to 8.03, respectively). Compared with the control, exercise training also significantly reduced BMI (MD: −0.47u2009kg/m2, 95% CIs: −0.89 to −0.06) and significantly improved scores in the ‘general health’ and ‘vitality’ sections of the 36-item Short Form Health Status Survey (SMD: 0.71, 95% CIs: 0.30 to 1.12; SMD: 0.81, 95% CIs: 0.40 to 1.23, respectively). Exercise training improved exercise capacity, left ventricular ejection fraction, and some the 36-item Short Form Health Status Survey scores, and reduced BMI in AF patients.

Abstract. [Purpose] This study aimed to evaluate the relationship between advanced glycation end-product accumulation and pulmonary function in a general population with normal spirometry results. [Subjects and Methods] A total of 201 subjects (mean age, 56 ± 11u2005years; males, 58%) enrolled in this study. Subjects were classified into two groups (younger group [<65u2005years old] and elderly group [≥65u2005years old]). Skin autofluorescence was assessed as an estimate of advanced glycation end-product. Forced vital capacity and forced expiratory volume in one second were measured using a spirometer, and the forced expiratory volume in one second/forced vital capacity ratio (FEV1/FVC) was calculated. [Results] Skin autofluorescence was not an independent factor associated with FEV1/FVC in the younger group, but both skin autofluorescence and pack-years of smoking were significant independent factors associated with FEV1/FVC in the elderly group. [Conclusion] Advanced glycation end-product accumulation, assessed by skin autofluorescence, is an independent factor negatively associated with FEV1/FVC in elderly people with normal spirometry results.
