BACKGROUND: Obese type 2 diabetic subjects are recently increasing in Korea, indicating the importance of insulin resistance rather than insulin secretory defects in the pathophysioloy of type 2 diabetes. The purpose of this study is to evaluate the safety and efficacy of fixed dose rosiglitazone/metformin combination therapy in poorly controlled subjects with type 2 diabetes mellitus. METHODS: 12 type 2 diabetic subjects who had a HbA1c > 11% or fasting plasma glucose > 15 mmol/L were included. After a 2 week screening period, the subjected took the fixed does rosiglitazone/metformin for 24 weeks. The treatment with rosiglitazone/metformin began at week 0 with an initial dose of 4 mg/1000 mg and, unless tolerability issues arose, subjects would be increased to 6 mg/1500 mg at week 4 and at week 8 to the maximum dose of 8 mg/2000 mg. The primary object of this study was to characterize the magnitude of HbA1c reduction from baseline after 24 weeks of rosiglitazone and metformin treatment in poorly controlled type 2 diabetics. RESULTS: The mean age of the subjects was 48.9 +/- 10.6 years old, body mass index was 25.0 +/- 3.5 kg/m2, HbA1c was 12.0 +/- 1.0%, and fasting plasma glucose was 16.3 +/- 3.1 mmol/L. HbA1c was reduced to 7.54 +/- 1.45% and fasting plasma glucose reduced to 7.96 +/- 2.38 mmol/L at week 24. The proportion of HbA1c responder who showed the reduction from baseline of > or = 0.7% or HbA1c < 7% was 11 among 12 subjects (91.7%). 41% of the subjects (5 among 12 subjects) achieved HbA1c level < 7.0% and 75% (9 among 12 subjects) achieved HbA1c level < 8.0%. CONCLUSIONS: In this study, rosiglitazone and metformin combination therapy was effective in glycemic control in poorly controlled subjects with type 2 diabetes mellitus.

OBJECTIVE: To assess the frequency and severity of sleep-disordered breathing (SDB) in subacute stroke patients in Korea. METHODS: We consecutively enrolled subacute stroke patients who were transferred to the Department of Rehabilitation Medicine from February 2016 to August 2016. The inclusion criteria were as follows: diagnosis of the first onset of cerebral infarction or hemorrhage in the brain by computed tomography or magnetic resonance imaging; patients between 18 and 80 years old; and patients admitted within 7 days to 6 months after stroke onset. We evaluated baseline clinical data on patients' admission to the Department of Rehabilitation Medicine. We assessed demographic data, stroke severity, neurologic impairment, cognition and quality of life. We used the Epworth Sleepiness Scale to assess quality of sleep. We used a portable polysomnography to detect SDB. RESULTS: Of the 194 stroke patients, 76 patients enrolled in this study. We evaluated and included 46 patients in the outcome analysis. The mean apnea-hypopnea index (AHI) was 24.2±17.0 and 31 patients (67.4%) exhibited an AHI ≥15. Those in the SDB group showed a higher National Institutes of Health Stroke Scale, lower Functional Ambulation Category, lower Korean version of Modified Barthel Index, and lower EuroQol five dimensions questionnaire (EQ-5D) at admission. Prevalence and clinical characteristics of SDB did not show significant differences among stroke types or locations. CONCLUSION: SDB is common in subacute stroke patients. SDB must be evaluated after a stroke, particularly in patients presenting severe neurologic impairment.

BACKGROUND: Neuromodulation therapy has been used to an adjunctive treatment promoting motor recovery in stroke patients. The objective of the study was to determine the effect of repetitive transcranial magnetic stimulation (rTMS) on neurobehavioral recovery and evoked potentials in rats with middle cerebral artery occlusion. METHODS: Seventy Sprague-Daley rats were induced permanent middle cerebral artery occlusion (MCAO) stroke model and successful stroke rats (n=56) assigned to the rTMS (n=28) and sham (n=28) group. The 10 Hz, high frequency rTMS gave on ipsilesional forepaw motor cortex during 2 weeks in rTMS group. The somatosensory evoked potential (SSEP) and motor evoked potential (MEP) were used to evaluate the electrophysiological changes. Behavioral function of the stroke rat was evaluated by the Rota rod and Garcia test. RESULTS: Forty rats (N(rTMS)=20; N(sham)=20) completed all experimental course. The rTMS group showed better performance than sham group in Rota rod test and Garcia test at day 11 (p<0.05) but not day 18 (p>0.05). The amplitude of MEP and SSEP in rTMS group was larger than sham group at day 18 (p<0.05). CONCLUSIONS: These data confirm that the high frequency rTMS on ipsilesional cerebral motor cortex can help the early recovery of motor performance in permanent middle cerebral artery stroke model and it may simultaneously associate with changes in neurophysiological activity in brain.

BACKGROUND: Type 2 diabetes is usually preceded by a long and clinically silent period of increasing insulin resistance. The purpose of this study is to demonstrate that rosiglitazone and metformin fixed-dose combination therapy (RSG/MET) will safely and effectively control glycemia as a first line of oral therapy, better than rosiglitazone (RSG) or metformin (MET) monotherapy in Korean type 2 diabetes patients. METHODS: This study was a 32-week, multicenter, randomized, double-blind study. Twenty-seven type 2 diabetes patients (males 14; females 13) were included and randomly divided into the rosiglitazone, metformin group, or rosiglitazone /metformin combination groups. The primary objective of this study was to determine the change in HbA1c from baseline (week 0) to week 32. The secondary end-points were to determine changes in fasting plasma glucose (FPG) and homeostasis model assessment insulin resistance (HOMA-IR), from baseline to week 32. Other cardiovascular risk markers were also assessed. RESULTS: At week 32, there were significant reductions in HbA1c and FPG, in all three treatment groups. There was no statistical difference in HbA1c among the three groups, but the decrease in FPG in the RSG/MET group was statistically significant compared to the MET group (P < 0.05). RSG/MET significantly reduced HOMA-IR at week 32 compared to baseline, but there was no difference among the three groups. RSG/MET significantly decreased high-sensitive C-reactive protein (hs-CRP) value at week 32, compared to baseline. There were increases in adiponectin from baseline to week 32 in the RSG and RSG/MET groups, and the increase in the RSG/MET group was statistically significant compared to that of the MET group (P < 0.05). At week 32, there was a significant decrease in plasminogen activator inhibitor-1 (PAI-1) in all three treatment groups, but no statistically significant difference among them. The RSG/MET group significantly decreased in terms of urinary albumin-creatinine ratio at week 32, compared to baseline. CONCLUSIONS: In this study, rosiglitazone and metformin combination therapy was effective in glycemic control as an initial therapy, and it improved cardiovascular risk markers in Korean type 2 diabetes patients.

Objective: To demonstrate the effect of daily treatment time on recovery of functional outcomes and how each type of rehabilitation treatment influences the improvement of subgroups of functional outcomes in stroke patients. Methods: We conducted a retrospective study in 168 patients who were admitted to the Department of Rehabilitation Medicine between 2015 and 2016. Patients who experienced their first-ever stroke and unilateral lesions were included. All patients underwent conventional rehabilitation treatment, and each treatment was administered one to two times a day depending on individual and treatment room schedules. Based on the mean daily treatment time, patients were divided into two groups: a high-amount group (n=54) and low-amount group (n=114). Outcomes were measured through the Korean version of Modified Barthel Index (MBI), FuglMeyer Assessment of the upper extremity, Trunk Impairment Scale (TIS), and Berg Balance Scale (BBS) scores on admission and at discharge. Results: The functional change and scores at discharge of MBI, TIS, and BBS were greater in the high-amount group than in the low-amount group. Among various types of rehabilitation treatments, occupational therapy training showed significant correlation with MBI, TIS, and BBS gain from admission to discharge. Conclusion The amount of daily mean treatment in post-stroke patients plays an important role in recovery. Mean daily rehabilitation treatment time seems to correlate with improved balance and basic activities of daily living after stroke.

OBJECTIVE: To evaluate the effect of anodal transcranial direct current stimulation (tDCS) over the lesioned leg motor cortex, which can enhance the strength and coordination of the contralateral lower extremity and furthermore, enhance the postural stability of the hemiplegic subject. METHODS: Anodal or sham stimulation on the lesioned cortex of a lower extremity was delivered to 11 ambulatory hemiplegic patients. The stimulation intensity was 2 mA. All subjects took part in two 10-minute tDCS sessions consisting of anodal stimulation and sham stimulation. The interval period between real and sham stimulation was 48 hours. The order was counter-balanced among the subjects. Before and after each stimulation session, static postural stability was evaluated with eyes opened and closed. Also, the isometric strength of the hemiplegic side of the treated knee was measured before and after each stimulation session. Repeated measure ANOVA was used to determine the statistical significance of improvements in postural stability and strength. RESULTS: There was significant improvement for overall stability index with eyes opened and closed after anodal tDCS (p<0.05). Isometric strength of the lesioned quadriceps tended to increase after anodal tDCS (p<0.05). Postural stability and quadriceps strength were not changed after sham stimulation. CONCLUSION: Anodal tDCS has potential value in hemiplegic stroke patients to improve balance and strengthen the affected lower extremity.

PURPOSE: Recent studies have reported the association of obesity and advanced stage prostate cancer. We researched the association between body mass index(BMI), which is widely used to diagnose obesity, and the prostate-specific antigen(PSA) screening test for prostate cancer. METERIALS AND METHODS: The authors examined the association between BMI and PSA for 26,193 men who visited the health promotion center at our medical center from July 1998 to June 2004. The BMI(weight in kg/height in m2) was calculated from the measured height and weight and this was categorized as follows: BMI<18.5(underweight), BMI 18.5-23.0(normal weight), BMI 23.0-27.5(overweight), BMI>27.5(obesity). We measured the mean PSA value of each BMI category. After adjust for age, we evaluated the PSA according to BMI by using error bars and 95% confidence intervals. RESULTS: The patients' age distribution was from 20 to 90 years old and their mean age was 46.1. The mean PSA value increased in a linear fashion with an increase in the age category(p<0.001), while it decreased in a linear fashion with an increase in the BMI category(p<0.001). After adjusting for age, the mean PSA value also decreased in a linear fashion with an increase in the BMI category(p<0.001). CONCLUSIONS: Men with an elevated BMI tend to have a lower value of PSA and to be misdiagnosed with prostate cancer. The PSA value should considered in relation to age and the BMI for the early detection of prostate cancer.

OBJECTIVE: To investigate the effects of a shoulder sling on balance in patients with hemiplegia. METHODS: Twenty-seven hemiplegic stroke patients (right 13, left 14) were enrolled in this study. The subjects' movement in their centers of gravity (COGs) during their static and dynamic balance tests was measured with their eyes open in each sling condition-without a sling, with Bobath's axillary support (Bobath sling), and with a simple arm sling. The percent times in quadrant, overall, anterior/posterior, and medial/lateral stability indexes were measured using a posturography platform (Biodex Balance System SD). Functional balance was evaluated using the Berg Balance Scale and the Trunk Impairment Scale. All balance tests were performed with each sling in random order. RESULTS: The COGs of right hemiplegic stroke patients and all hemiplegic stroke patients shifted to, respectively, the right and posterior quadrants during the static balance test without a sling (p<0.05). This weight asymmetry pattern did not improve with either the Bobath or the simple arm sling. There was no significant improvement in any stability index during either the static or the dynamic balance tests in any sling condition. CONCLUSION: The right and posterior deviations of the hemiplegic stroke patients' COGs were maintained during the application of the shoulder slings, and there were no significant effects of the shoulder slings on the patients' balance in the standing still position.

OBJECTIVE: To examine the association between motor evoked potentials (MEPs) in lower limbs and ambulatory outcomes of hemiplegic stroke patients. METHODS: Medical records of hemiplegic patients with the first ever stroke who received inpatient rehabilitation from January 2013 to May 2014 were reviewed. Patient who had diabetes, quadriplegia, bilateral lesion, brainstem lesion, severe musculoskeletal problem, and old age over 80 years were excluded. MEPs in lower limbs were measured when they were transferred to the Department of Rehabilitation Medicine. Subjects were categorized into three groups (normal, abnormal, and absent response) according to MEPs findings. Berg Balance Scale (BBS) and Functional Ambulation Category (FAC) at initial and discharge were compared among the three groups by one-way analysis of variance (ANOVA). Correlation was determined using a linear regression model. RESULTS: Fifty-eight hemiplegic patients were included. BBS and FAC at discharge were significantly (ANOVA, p<0.001) different according to MEPs findings. In linear regression model of BBS and FAC using stepwise selection, patients' age (p<0.01), BBS at admission (p<0.01), and MEPs (p<0.01) remained significant covariates. In regression assumption model of BBS and FAC at admission, MEPs and gender were significant covariates. CONCLUSION: Initial MEPs of lower limbs can prognosticate the ambulatory outcomes of hemiplegic patients.
