Background: The aim of this study was to compare the effects of 10 weeks of resistance or treadmill exercises on glycemic indices levels prior to and immediately following exercise in adults with type 2 diabetes. Research Design and Method: Twenty inactive subjects (mean age 53.5 years) with type 2 diabetes enrolled in the study. Baseline HbA1c, blood glucose levels, heart rate, and blood pressure were measured for each subject prior to the initiation of the exercise program. Subsequently, subjects were matched to age, waist circumference and sex and assigned to either isocaloric resistance or treadmill exercise groups, which met 3 times per week for 10 weeks. Results: Both groups showed a reduction in pre and post-exercise blood glucose and HbA1c values. There was no change in resting blood pressure or heart rate in either group during the course of the 10 week intervention. The group receiving resistance exercises showed significant differences in the daily pre-exercise plasma glucose readings between the beginning and end of the exercise protocol (p < 0.001). There were significant improvements in the mean HbA1c reading pre and post training in both groups (p < 0.001). However, the greater reduction was noted in the resistance exercise group, and at 10 weeks their HbA1c levels were significantly lower than the group that received treadmill exercises (p < 0.006). Conclusion: Ten weeks of resistance exercises were associated with a significantly better glycemic control in adults with type 2 diabetes compared to treadmill exercise.

Goals and objectives: The main goal of this study is to evaluate the effect of treadmill exercise on the angiogenesis markers in the striatum (ST) of chronic/progressive parkinsonian mice. Materials and Methods: Forty 57BL/6 albino mice were randomly divided into four groups. Sedentary control (SC, n = 10), exercise control (ExC, n = 10), sedentary Parkinson’s (SPD, n = 10), and exercised Parkinson’s (ExPD, n = 10). Parkinsonism was induced by the injection with 10 doses of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine, (25 mg/kg) and probenecid (250 mg/kg) over 5 weeks, three days and half a part. Following the induction of parkinsonism, ExPD and ExC animal groups were trained on a modified human treadmill at a speed of 18 m/min, 0° of inclination, 40 min/day, 5 days/week for 4 weeks. The remaining two groups (SPD and SC) were housed in cages for the same period. At the end of the experiment, the angiogenesis markers; Vascular Endothelial Growth Factor (VEGF) and CD34 were examined in the striatum in the four animal groups. Results: PD resulted in a significant decrease in blood vessel density with the comparison between the sedentary control and PD model animals ( p < 0.005). Four weeks of treadmill exercise training significantly increased angiogenesis in the striatum in ExPD groups ( p < 0.05). Exercise also induced an increase in blood vessel density in the striatum of the control animals, but the change was not significant ( P < 0.3). Conclusion: These data suggest that 4 weeks of treadmill exercise promoted angiogenesis in the brain of chronic Parkinsonian mice, which can partially explain the beneficial role exercise in patients with PD. Further studies are required to determine the mechanism of exercise-induced angiogenesis in PD.

Objective: Craniotomy and evacuation is the standard treatment of acute epidural hematoma (EDH). Here, the authors report their experience in nonoperative management of acute EDH in children with mild head injury. Methods: The authors retrospectively reviewed charts of patients with conservatively treated EDH at the Department of Neurosurgery, King Abdulla University Hospital, Irbid, Jordan, between August 2003 and October 2007. All patients had a Glasgow Coma Scale score of 14 or 15, and an initial computerized tomography (CT) scan demonstrating an EDH with or without skull fractures. Follow-up included neurological examination and brain CT. Results: Six children (3 boys, 3 girls) with acute EDH were successfully managed at our department without surgical intervention. The Glasgow Outcome Scale score of all patients was 5, with no posttraumatic sequelae. Follow-up brain CT showed complete resolution of the EDH within 2–3 months. Conclusions: Our results demonstrated that pediatric EDH can be managed nonoperatively. The pronounced increase in the number of CT examinations for patients with head injuries has resulted in a greater proportion of EDH detected in conscious patients. We recommend such treatment be performed in specialized pediatric neurosurgical centers under close neurological observation.

Background: Early markers of diabetic autonomic neuropathy (DAN) in an electrocardiogram (ECG) include elevated R wave amplitudes, widening of QT_c intervals and decreased heart rate variability (HRV). The severity of DAN has a direct relationship with mortality risk. Aerobic exercise training is a common recommendation for the delay and possible reversal of cardiac dysfunction. Limited research exists on ECG measures for the evaluation of aerobic exercise training in Zucker Diabetic Fatty (ZDF) rat, a model of type 2 diabetes. The objective of this study was to assess whether aerobic exercise training may attenuate diabetes induced ECG changes. Methods: Male ZDF (obese fa/fa) and control Zucker (lean fa/+) rats were assigned to 4 groups: sedentary control (SC), sedentary diabetic (SD), exercised control (EC) and exercised diabetic (ED). The exercised groups began 7 weeks of treadmill training after the development of diabetes in the ED group. Baseline (prior to the training) and termination measurements included body weight, heart weight, blood glucose and glycated hemoglobin levels and ECG parameters. One way repeated measures ANOVA (group) analyzed within and between subject differences and interactions. Pearson coefficients and descriptive statistics described variable relationships and animal characteristics. Results: Diabetes caused crucial changes in R wave amplitudes (p < 0.001), heart rate variability (p < 0.01), QT intervals (p < 0.001) and QT_c intervals (p < 0.001). R wave amplitude augmentation in SD rats from baseline to termination was ameliorated by exercise, resulting in R wave amplitude changes in ED animals similar to control rats. Aerobic exercise training neither attenuated QT or QT_c interval prolongation nor restored decreases in HRV in diabetic rats. Conclusion: This study revealed alterations in R wave amplitudes, HRV, QT and QT_c intervals in ZDF rats. Of these changes, aerobic exercise training was able to correct R wave amplitude changes. In addition, exercise has beneficial effect in this diabetic rat model in regards to ECG correlates of left ventricular mass.

The goal of this study is to investigate the effectiveness of constraint-induced movement therapy (CIMT) on the Barthel Index (BI) scores in persons with stroke to assess dependency in survivers of stroke and to investigate the long-term effects of CIMT on dependency needs as measured by the BI, based on the hypothesis that CIMT as home-based therapy would be of significant benefit in stroke rehabilitation. Twenty-seven participants, 16 men with a mean age of 58 (+/- 10.8) and 4 women with a mean age of 60 (+/- 6.3), participated in the study as an experimental group, and 17 participants, 12 men with a mean age of 58 (+/- 9.7) and 5 women with a mean age of 55 (+/-11.8), participated as a control group. The experimental/treatment group received traditional therapy with the CIMT where the intact contralateral upper limb was placed in a removable cast for 6 hours a day during waking hours for 4 weeks. The control group received traditional therapy only. Both groups were assessed using the BI on admission and on discharge from rehabilitation. In addition, 18 participants (14 male and 4 female), 64% of the experimental group, were reevaluated using the BI for the long-term benefits of CIMT on dependency. Using unpaired t test (SPSS version 15), statistically significant improvement was noted in the BI for the experimental group compared to the control group. After 6 months follow-up, BI was 96.3 +/- 2.7, indicating that the obtained gains were maintained at 6 months post discharge, compared to their BI score at 4 weeks (68.2 +/- 3.8) post CIMT (p value < .005). Following stroke, patients who received CIMT every day for 4 weeks in conjunction with traditional rehabilitation therapy showed significant changes in the BI upon discharge and this positive outcome was preserved after 6 months follow-up. This improvement indicates an overall significant improvement in ADL status for patients who received CIMT and has implications for future use in stroke rehabilitation as home-based therapy for stroke rehabilitation.
