BACKGROUND: The typical Korean diet includes rice, which is usually served in a rice bowl. We investigated the effects of a meal plan using rice bowls of varying sizes on dietary energy intake (EI), body weight (BW), and blood glucose levels. METHODS: Forty-two obese women with type 2 diabetes mellitus were randomly assigned to use either a 200 mL small rice bowl (SB), a 380 mL regular rice bowl (RB), or to a control group (C). Both intervention groups were asked to reduce their EI by 500 kcal/day for 12 weeks and simple instructions for using the assigned bowl were provided. Dietary EI and proportion of macronutrients (PMN) were estimated from 3-day dietary records. RESULTS: Reduction of EI was more prominent in the SB group compared to the RB and C group, although EI decreased significantly from baseline in all groups. Carbohydrate and fat intakes of the SB group were decreased greater than those of the RB and C group. However, changes in PMN were not significant across the 3 groups. Reduction of BW and HbA1c levels in the SB group was more prominent compared to the C group. Although, BW and HbA1c were decreased significantly from baseline in both bowl groups. There was no statistical difference between the two groups. CONCLUSION: The small rice bowl-based meal plan was effective at reducing EI, BW, and blood glucose levels, and the observed reductions in EI, carbohydrate, and fat intake were greater than those of the regular rice bowl-based meal plan.

BACKGROUND: There is controversy over whether aerobic or resistance exercise is more effective for improving endothelial function in type 2 diabetes mellitus (T2DM). This study was aimed to investigate the effects of an aerobic and resistance training program on endothelial function, and the influences of glycemic control, body weight changes, and aerobic capacity in T2DM. METHODS: Total 40 overweight women with T2DM were assigned into 3 groups: an aerobic exercise group (AEG, n=13), resistance exercise group (REG, n=12), and control group (CG, n=15), and followed either brisk walking for the AEG or resistance band training for the REG, 60 minutes per day, 5 days per week for 12 weeks with monitoring daily activity using accelerometers. We assessed endothelial function by flow-mediated dilation (FMD), and aerobic capacity by oxygen uptake at anaerobic threshold (AT_VO2) at baseline and following training program. RESULTS: The mean participants' age was 57.0+/-6.8 years, and body mass index (BMI) was 27.0+/-2.3 kg/m2. After intervention, FMD increased by 2.2+/-1.9% in AEG, which differed from REG and CG (P=0.002), despite of decreased body weight (BW) in both AG and RG (2.8+/-2.5%, P=0.002; 1.6+/-2.0%, P=0.017, respectively). A significant increased AT_VO2 and decreased HbA1c were found only in AEG. In all participants, FMD was changed with the significant relations to the AT_VO2 (r=0.348, P=0.035), but not to HbA1c levels or BW. CONCLUSION: Aerobic exercise appears to be more beneficial than resistance exercise for improving endothelial function in T2DM. In addition, aerobic capacity could be a better predictor of changes in FMD than BW and glycemic control.

BACKGROUND: Aerobic exercise can effectively reduce visceral fat. However, few studies have examined the effect of daily physical activity on obesity and cardiopulmonary function in the subjects with diabetes. We examined the effect of moderate intensity of walking in obese diabetes patients by monitoring of daily activity and measuring the change in abdominal fat area, muscle are and maximal muscle strength. METHODS: We randomly assigned 27 obese women with type 2 diabetes to an aerobic exercise group (AG, n = 13) and control group (CG, n = 14). The AG performed moderate intensity walking for 60 minutes per exercise, 5 times per week, and for 12 weeks. The activity energy expenditure was monitored by a multi-record accelerometer. The CG maintained routine daily activities. At the time of the initiation of the study and after 12 weeks of exercise, the aerobic exercise capacity was assessed using oxygen consumption rate at anaerobic threshold (VO2-AT). The abdominal fat area and the quadriceps muscle area were measured by computed tomography, and the maximum muscle strength of the upper and lower limbs was measured by a chest press and a leg press, respectively. RESULTS: The mean age of the study subjects was 56.6 +/- 8.0 years, the mean duration of diabetes was 6.3 +/- 6.0 years, and the body weight index (BMI) was 27.3 +/- 2.7 kg/m2. The BMI of the AG was significantly decreased (P = 0.003). In the AG, the visceral fat area and subcutaneous fat area were also significantly decreased (P = 0.018 and P < 0.001, respectively) but not in CG. VO2-AT of the AG was significantly improved, while that of the CG did not change (P = 0.009 and P = 0.115, respectively). The quadriceps muscle mass and the maximal muscle strength of the AG did not change, however, the CG showed a significant decrease. Duration of moderate intensity exercise was correlated with the decrease in total abdominal fat area (r = -0.484; P = 0.011) and that of high intensity exercise was correlated with improvement of cardiopulmonary function (r = 0.414; P = 0.032). CONCLUSION: Daily moderate intensity aerobic exercise is effective at reducing abdominal fat mass, while high intensity exercise improves cardiopulmonary function.

BACKGROUND: Weight loss through low-calorie diets (LCDs) decreases visceral fat (VF). However, the effects on muscle mass, changes of dietary quality, and insulin sensitivity are unknown for Korean obese type 2 diabetic subjects. Therefore, this study examined such effects of LCDs. METHODS: A total of 30 obese type 2 diabetic subjects (body mass index, 27.0 +/- 2.2 kg/m2) were randomly assigned to an LCD or control group. Subjects on LCDs took 500~1,000 kcal fewer energy than their usual dietary intake (1,000~1,500 kcal/day) over the course of 12 weeks. The abdominal VF and femoral muscle mass were evaluated by computed tomography, and insulin sensitivity was assessed using an insulin tolerance test (Kitt; rate constant for plasma glucose disappearance, %/min). Dietary nutrient intake consumed by subjects was assessed by 3-day food records. RESULTS: The percent VF reduction was -23.4 +/- 17.2% in the LCD group and -9.8 +/- 11.8% in the control group after 12 weeks (P < 0.001, P = 0.002). However, significant decrease in femoral mass or proportional change of marcronutrient intake and mean adequacy ratio were not found in the LCD group, as compared to the control group. Insulin sensitivity improved in the LCD group, as compared to the control group (P = 0.040). CONCLUSION: LCD effectively improved insulin sensitivity and reduced abdominal VF without reduction of femoral muscle and dietary quality in obese type 2 diabetic subjects.

BACKGROUND: Combination fitness regimens (including aerobic and resistance exercises) are effective for improving cardio-respiratory fitness, reducing visceral fat and increasing insulin sensitivity in diabetic patients. The combination exercise intensity that a patient is capable of is limited by his or her aerobic capacity and one repetition maximum (1RM). We investigated the relationships between 1RM, aerobic exercise capacity and body mass index in patients with type 2 diabetes. METHODS: A total of 177 (men: 85, women: 92) diabetic subjects with HbA1c < or = 10% were enrolled. Muscle strength and 1RM were assessed bychest press (upper body) and leg press (lower body). We assessed aerobic capacity by VO2max and muscle mass by bioimpedance analysis. RESULTS: There was no correlation between 1RM and VO2max in type 2 diabetic patients (upper: P = 0.122, lower: P = 0.138 for men, and upper: P = 0.952, lower: P = 0.570 for women). However, 1RM was significantly correlated with muscle mass both in men and women (upper: r = 0.493, P < 0.001, r = 0.315, P = 0.002 lower: r = 0.437 P < 0.001, r = 0.307, P =0.003, respectively). There was also a significant correlation between 1RM and BMI. In obese male subjects with BMI > or = 25 kg/m2, we observed a significant correlation between muscle mass and BMI (r = 0.374, P = 0.032), but this correlation was not observed in women. CONCLUSION: Clinicians treating Korean type 2 diabetic subjects should recommend resistance exercise to their patients. In particular, obese women with diabetes may receive greater benefits by increasing muscle mass through resistance exercises.

BACKGROUND: Insulin resistance is related to central obesity and the amount of skeletal muscle. A simple and practical anthropometric marker for muscle mass is not known, although waist circumference (WC) is used as an indicator of abdominal obesity. The aims of this study were to investigate whether arm (AC) and thigh circumferences (TC) can be used as an indicator of muscle mass and if they are related to muscle strength. METHODS: A total of 110 obese (body mass index [BMI]> or =25 kg/m2) women with type 2 diabetes were enrolled, and WC, AC, and TC were measured. Abdominal visceral fat (AVF), subcutaneous fat (ASF), and total fat (ATF) were assessed by computed tomography, regional muscle (MM), and fat mass by dual-energy X-ray absorptiometry, muscle strength by one repetition maximum (1RM) of both extremities (chest and leg press) and insulin resistance by KITT. RESULTS: The mean age was 56.2+/-7.3 years, duration of diabetes was 4.2+/-4.4 years, and BMI was 27.2+/-2.8 kg/m2. WC was correlated with ATF, AVF, and ASF (r=0.728, P<0.001; r=0.515, P<0.001; r=0.608, P<0.001, respectively). Arm MM was correlated with AC (r=0.500, P<0.001), and leg MM with TC (r=0.291, P=0.002). Upper 1RM was related to AC/WC ratio (r=0.359, P<0.001), and lower 1RM was to TC/WC ratio (r=0.286, P=0.003). Insulin resistance had significant relations with AVF, WC, and total MM (r=-0.262, P=0.008; r=-0.217, P=0.029; r=0.160, P=0.031, respectively). CONCLUSION: The muscle mass was related to extremity circumferences, and muscle strength was to extremity/waist circumference ratio in obese women with type 2 diabetes.

Disseminated cryptococcosis mainly occurs in immunocompromised patients. It enters the body through the respiratory tract and spreads to the lungs, skin, liver and lymphoid organs. Among cryptococcosis, cryptococcal meningitis is a relatively frequent manifestation and causes serious morbidity and mortality. It needs urgent diagnosis and initiation of effective antifungal therapy. It is difficult to differentiate cryptococcal meningitis from neuropsychiatric lupus due to similar clinical symptoms, laboratory and cerebrospinal fluid findings. We report a case of disseminated cyrptococcosis in a patient with systemic lupus erythematosus being managed with mycophenolate mofetil, prednisolone and hydroxychloroquine.

BACKGROUND: Arterial stiffness is an important factor in atherosclerosis. Thus we examined whether aerobic exercise could reduce arterial stiffness in obese women with type 2 diabetes without diabetic complication. METHODS: A total of 35 women with type 2 diabetes (body mass index, 26.6+/-2.8 kg/m2; age, 56.4+/-1.9 years; duration of diabetes, 4.7+/-4.8 years) were assigned to aerobic exercise group (AEG) or control group (CG). AEG completed a 12-week exercise program (3.6 to 5.2 metabolic equivalents, 3 day/week, 60 min/day), with their exercise activities monitored by accelerometers. We measured abdominal total fat area (TFA), visceral fat area (VFA), and subcutaneous fat area (SFA) by computed tomography, insulin sensitivity by insulin tolerance test (K(ITT)), and augmentation index (AIx) by SphygmoCor at baseline and at the end of the 12-week program. RESULTS: The AIx was improved in the AEG compared with the CG (P<0.001). The percent change of AIx had significant correlation with the improvement of physical activity energy expenditure (PAEE), aerobic capacity, TFA, and SFA (r=-0.416, P=0.013; r=0.560, P<0.001; r=0.489, P=0.003; r=0.531, P=0.001, respectively), but not with insulin sensitivity, energy intake, or VFA. CONCLUSION: Improvement in aortic stiffness by aerobic exercise is related with the improvement of aerobic capacity, PAEE, and total fat but not with insulin sensitivity or energy intake in obese women with type 2 diabetes.
