Aim: To determine the optimal cut-off value of serum total adiponectin for managing the risk of developing metabolic syndrome (MetS) in male Japanese workers. Methods: A total of 365 subjects without MetS aged 20–60 years were followed up prospectively for a mean of 3.1 years. The accelerated failure-time model was used to estimate time ratio (TR) and cut-off value for developing MetS. Results: During follow-up, 45 subjects developed MetS. Age-adjusted TR significantly declined with decreasing total adiponectin level (≤ 4.9, 5.0–6.6, 6.7–8.8 and ≥ 8.9 μg/ml, P for trend = 0.003). In multivariate analyses, TR of MetS was 0.12 (95% CI 0.02–0.78; P = 0.03) in subjects with total adiponectin level of 5.0–6.6 μg/ml, and 0.15 (95% CI 0.02–0.97; P = 0.047) in subjects with total adiponectin level ≤ 4.9 μg/ml compared with those with total adiponectin level ≥ 8.9 μg/ml. The accelerated failure-time model showed that the optimal cut-off value of total adiponectin for managing the risk of developing MetS was 6.2 μg/ml. In the multivariate-adjusted model, the mean time to the development of MetS was 78% shorter for total adiponectin level ≤ 6.2 μg/ml compared with > 6.2 μg/ml (TR 0.22, 95% CI: 0.08–0.64, P = 0.005). Conclusion: Our findings suggest that the cut-off value for managing the risk of developing MetS is 6.2 μg/ml in male Japanese workers. Subjects with total adiponectin level ≤ 6.2 μg/ml developed MetS more rapidly than did those with total adiponectin level > 6.2 μg/ml. [ABSTRACT FROM AUTHOR]

Objective: To investigate the effects of nurse-led exercise interventions, in addition to standard rehabilitation, on patients suffering from hemiplegia soon after stroke onset. Methods: Interventions involved a series of hip bridges. Efficacy was evaluated by monitoring leg muscle mass. Participants were divided into control, intervention and terminated intervention groups. In addition to standard rehabilitation, the intervention group performed a series of hip bridges once a day. Leg muscle mass was evaluated using dual-energy X-ray absorptiometry (DXA). Measurements were taken 3-5 days after stroke onset, then again 7 days after initial measurement. Results: During the first week, the mean decrease in leg muscle mass on the paralyzed side was 417 g (7%) for the control group, 304 g (6%) for the terminated intervention group and 108 g (2%) for the intervention group. Only the difference between control and intervention groups was significant (P=0.008). Conclusions: Exercise interventions comprising a series of hip bridges soon after stroke onset, in addition to standard rehabilitation, can reduce leg muscle atrophy on the paralyzed side in stroke patients.

The purpose of the present study was to evaluate the efficacy of a newly designed rehabilitation program for postoperative patients with breast cancer. This was achieved through examinations to clarify the range of motion (ROM) of the shoulder joint, postoperative pain and recovery of activities of daily living (ADL). The ROM of the shoulder joint was evaluated with respect to five items and determinations were carried out five times. Patients were orally questioned four times regarding their pain after surgery, movement-associated chest pain, pain at night and operative wound pain. Evaluation of the ADL after discharge was conducted using a three-level rating method at postoperative week 4 and week 12. A total of 72 patients were studied, comprising 39 who underwent pectoral muscle-conserving mastectomy and 33 who underwent breast-conserving surgery. The arm movement of forward raising showed the greatest decline, followed by lateral raising of the arm. Postoperative time-course changes in internal/external arm rotation, as well as backward arm raising were slight. Comparison of the operative procedures revealed differences only for lateral arm raising at postoperative week 4, while there were no differences in any of the shoulder joint movements. Lowering of the ROM of the shoulder joint was more marked at an earlier time (week 1 to week 2) after surgery, but it was not statistically significant. Pain at night and operative wound pain were prolonged over the period, and reported in postoperative week 1 to week 12 by 3–15% of patients. All ADL items became almost normal in approximately 90% of patients at postoperative week 4. The efficacy of the present rehabilitation program early after surgery was demonstrated in terms of recovery of ADL as well as the ROM of the arm on the affected side. [ABSTRACT FROM AUTHOR]

Emerging evidence suggests that adiponectin secreted from adipocytes may have a preventive effect on the development of type 2 diabetes, attributable to an increase in insulin sensitivity and suppression of inflammation. However, when the East Asian population is considered, dysfunction of insulin secretion, besides insulin resistance and inflammation, has been assumed to play a significant role in the development of diabetes. Thus, the aim of the present study was to examine whether there is an association between a decrease in serum total adiponectin level and the incidence of diabetes in male Japanese, with consideration of insulin secretory function. We here report a prospective occupational-based cohort study, which was conducted during 2010-2019 in Japan. Briefly, 851 male workers without diabetes aged over 20 years were followed up prospectively. Diabetes was defined as either: 1) fasting plasma glucose ≥ 126 mg/dl, 2) HbA1c ≥ 6.5%, 3) medication for hyperglycemia or 4) postprandial plasma glucose ≥ 200 mg/dl during the follow-up period. Hazard ratios (HRs) with 95% confidence intervals (CIs) of serum total adiponectin level for the incidence of diabetes were estimated using a Cox proportional hazards model. In multivariate analysis after adjusting for age, BMI, smoking habit, alcohol intake, regular exercise, family history of diabetes, HDL-C, triglyceride, hypertension and HOMA-β, HR of developing diabetes was 8.61 [95%CI: 1.87 to 39.77, P=0.01] in the lowest quartile of serum total adiponectin, compared with the highest quartile. Furthermore, the risk of diabetes was 36% higher (P<0.01) per 1 µg/ml decrement of serum total adiponectin level in the multivariate-adjusted model. These results suggest that serum total adiponectin level could be a biomarker for the onset of diabetes in male Japanese, even with consideration of the ability of fasting insulin secretion and adjustment of its impact.

Serum 1,5-anhydroglucitol (1,5-AG) is a useful clinical indicator for short-term glycemic control status, which exhibits a rapid decrease if blood glucose levels are poorly controlled in diabetic patients. Interestingly, some cross-sectional studies have suggested that serum 1,5-AG level decreases even before the onset of type 2 diabetes. Thus, the aim of the present study was to examine whether there is an association between a decrease in serum 1,5-AG level and the incidence of abnormal glucose metabolism (AbGM) or metabolic syndrome (MetS) in Japanese in a prospective cohort study. We here report a prospective occupational-based cohort study, which was conducted during 2010-2017 in Japan. Briefly, 1) 837 male workers without AbGM and 2) 843 male workers without MetS aged over 20 years were followed up prospectively. AbGM was defined as either: 1) fasting plasma glucose ≥ 110 mg/dl, 2) HbA1c ≥ 6.0% or 3) medication for hyperglycemia. In multivariate analysis after adjusting for age, BMI, smoking habit, alcohol intake, regular exercise and estimated glomerular filtration rate, the HR of developing MetS was 1.81 [95%CI: 1.12 to 2.92, P=0.01] in the lowest quartile of baseline serum 1,5-AG, compared with the highest quartile. In addition, the incidence and multivariate-adjusted HR of AbGM or MetS also increased with decreasing quartile of serum 1,5-AG (P for trend for both <0.05). Our findings suggest that a decrease in serum 1,5-AG level is a predictive marker for the future onset of AbGM or MetS in male Japanese. Disclosure: A. Hata: None. N. Aki: None. T. Ichihara: None. A.

Few prospective cohort studies have examined the association between serum fatty acid (FA) proportions and type 2 diabetes (T2D). In addition, the involvement of serum FAs in the development of early stage abnormality of glucose homeostasis remains unclear. The present study investigated the association between serum FA proportions or FA ratios, which reflect desaturase activity, and the incidence of early stage abnormal glucose metabolism before the actual onset of T2D. We here report a prospective occupational-based cohort study, which has been conducted since 2008 in Japan. A total of 396 male workers without abnormal glucose metabolism aged 20 to 60 years were followed-up prospectively (mean follow-up period: 5.9 years). Abnormal glucose metabolism was defined as either: 1) fasting plasma glucose ≥ 110 mg/dl, 2) HbA1c ≥ 6.0% or 3) medication for hyperglycemia. We evaluated serum FA proportions and the activities of ⊿5desaturase, ⊿6desaturase and ⊿9desaturase, which reflect desaturation of FAs estimated from the FA product-to-precursor ratios. In multivariate analysis after adjusting for age, BMI, smoking habit, alcohol intake, regular exercise, HDL cholesterol, triglycerides, family history of diabetes, and hypertension, the HR of developing abnormal glucose metabolism was 4.42 [95% CI: 1.81 to 10.76, P=0.001] in the highest quartile of baseline serum dihomo-γ-linolenic acid proportion, compared with the lowest quartile. In addition, the age-adjusted incidence and multivariate-adjusted HR of abnormal glucose metabolism also increased with increasing quartile of ⊿6desaturase (P for trend for both <0.01). Our findings suggest that increased serum dihomo-γ-linolenic acid proportion and enhanced activity of ⊿6desaturase are predictive markers for the development of early stage abnormal glucose metabolism in male Japanese. These results imply that altered FA metabolism may associate with early stage disorders of glucose metabolism. Disclosure: A. Hata: None. N. Aki: None. T. Ichihara: None. A. Tamura: None. T.
