RESUMEN
Objective@#: Early successful reperfusion is associated with favorable outcomes in acute ischemic stroke (AIS). The purpose of this study was to achieve successful recanalization by a combined mechanical thrombectomy technique, the Aspiration-Retriever Technique for Stroke (ARTS), which is composed of a flexible large lumen distal access catheter and a retrievable stent as the first-line strategy of mechanical thrombectomy. @*Methods@#: We retrospectively reviewed 62 patients with AIS who underwent mechanical thrombectomy from 2018 to 2019 at our institute by a senior neurointerventionalist. Among them, patients who were treated using the ARTS technique with the soft torqueable catheter optimized for intracranial access (SOFIA®; MicroVention-Terumo, Tustin, CA, USA) as the first-line treatment were included. Patients who had tandem occlusions or underlying intracranial artery stenosis were excluded. The angiographic and clinical outcomes were evaluated. The angiographic outcome was analyzed by the rate of successful recanalization, defined as a Thrombolysis in Cerebral Infarction score of 2b or 3 at the end of all procedures and the rate of successfully achieving the first pass effect (FPE), defined as complete recanalization with a single pass of the device. The clinical outcomes included the National Institutes of Health Stroke Scale (NIHSS) score, modified Rankin Scale (mRS), and mortality. @*Results@#: A total of 27 patients (mean age, 59.3 years) fulfilled the inclusion criteria. The successful recanalization rate was 96% (n=26) while the FPE rate was 41% (n=11). The mean post-procedural NIHSS change was -3.0. Thirteen patients (48%) showed good clinical outcomes after thrombectomy with the ARTS technique (mRS at 90 days ≤2). Postoperative complications occurred in seven of 25 patients : hemorrhagic transformation in six patients (22%) and distal embolization in one patient (4%). Mortality was 15% (n=4). @*Conclusion@#: Although the clinical outcomes using the ARTS technique with a flexible large lumen distal access catheter performed as the frontline thrombectomy in patients with AIS were not significantly superior than those of other studies, this study showed a high rate of successful endovascular recanalization which was comparable to that of other studies. Therefore, ARTS using the SOFIA® catheter can be considered as the first choice of treatment for AIS due to large vessel occlusion.

RESUMEN
OBJECTIVE: A defense mechanism is an automatic psychological process necessary for successful adaptation. It reflects adaptive capacity. The purpose of this study is to explore the relationship between the adaptation ability of individuals who face mandatory military service and the pattern of defense mechanisms. METHODS: The subjects were 69 men (21.4±2.2 years) who expressed psychological difficulties in three military service situations. Control group was 36 men (24.0±1.4 years) who had successfully completed military service. We examined psychiatric history, the pattern of defense mechanisms, and depression and anxiety levels. Defense mechanisms were compared between two groups. RESULTS: The maladjusted group used immature defenses more frequently than the control group did. There were no differences in the defense patterns according to diagnosis. The control group used more identification and rationalization, classified as immature defenses. The temporarily maladjusted group used more somatization, regression, and avoidance. CONCLUSION: Using mature defense mechanisms helped young adults to adapt to a particular situation. The maturity of the defense is more valuable than the psychiatric diagnosis. Some immature defenses are also helpful to adapt. We cautiously assume that some defenses can be protective or risk factors in adapting to stressful situations by young adults.

PURPOSE: This study estimated the prevalence of lower urinary tract symptoms (LUTS) in Korean men and the conditions for being diagnosed with or treated for LUTS/benign prostatic hyperplasia (BPH). METHODS: We analyzed cross-sectional data collected from 69,851 Korean men who were 40 years of age or older and had participated in the Korean Community Health Survey performed in 2011. Interviewers performed face-to-face surveys that included sociodemographic questions, the International Prostate Symptom Score (IPSS), and questions regarding whether the subjects had been diagnosed with or treated for LUTS/BPH. We estimated the prevalence of LUTS and assessed whether the subjects had been diagnosed with or treated for LUTS/BPH. RESULTS: Moderate to severe LUTS, storage symptoms, and voiding symptoms increased with age. The IPSS quality of life score was 1.5±0.004 in the mild LUTS group (n=57,701), 3.3±0.01 in the moderate LUTS group (n=9,203), and 4.3±0.02 in the severe LUTS group (n=2,947) (P<0.0001). The prevalence of moderate to severe LUTS in those who had not been diagnosed with LUTS/BPH was 64.5% (7,847 of 12,150), and the prevalence of moderate to severe LUTS in those who had been diagnosed with LUTS/BPH but had not been treated was 23.5% (2,853 of 12,150). CONCLUSIONS: The severity of LUTS in Korean men increased with age, and the IPSS quality of life score increased with the severity of LUTS. Many Korean men with moderate to severe LUTS had not been diagnosed or treated for LUTS/BPH. Socioeconomic conditions played an important role in health-seeking behavior among patients with LUTS/BPH.

OBJECTIVES: Whether daytime sleepiness is proportional to the severity of sleep apnea in obstructive sleep apnea syndrome (OSAS) is controversial. In this study we investigated how insomnia severity affects the association between daytime sleepiness and sleep apnea severity in OSAS. METHODS: The present study included 235 male subjects who were diagnosed with OSAS based on clinical history and nocturnal polysomnography. Pearson's correlation analysis was conducted among sleep and mood-related self-reported data, polysomnographic data and demographic data of all subjects. Based on Pittsburgh Sleep Quality Index (PSQI), the subjects were divided into 2 groups; group A (n = 75; PSQI 5). Partial correlation analysis was performed between the Epworth Sleepiness Scale (ESS) and other data in both groups. Multiple linear regression analysis was conducted to investigate the factors which affected the ESS in group A. RESULTS: Pearson's correlation analysis showed weak or non-existent correlations between ESS and apnea severity data such as apnea-hypopnea index (AHI) (r = 0.148, p = 0.023), apnea index (AI) (r = 0.137, p = 0.036), hypopnea index (HI) (r = 0.058, p = 0.377), oxygen desaturation index (ODI) (r = 0.149, p = 0.022) and arousal total index (ATI) (r = 0.129, p = 0.048). Positive correlations between ESS and apnea severity data such as AHI (r(p) = 0.313, p = 0.008), AI (r(p) = 0.339, p = 0.004), ODI (r(p) = 0.289, p = 0.015) and ATI (r(p) = 0.256, p = 0.031) were observed only in group A. Multiple regression analysis showed that AI (t = 2.996, p = 0.004) and BAI (t = 2.721, p = 0.008) were associated with ESS in group A. CONCLUSION: The correlation between daytime sleepiness and sleep apnea severity was shown only in group A. This result suggests that associations between daytime sleepiness in OSAS and sleep apnea severity will become prominent when controlling for insomnia-related variables.

PURPOSE: We investigated the prevalence rate of benign prostatic hyperplasia (BPH) among Korean males in a rural area through a cross-sectional, community-based epidemiologic survey and analyzed the correlation with epidemiologic factors. MATERIALS AND METHODS: A total of 779 males who lived in Yangpyeong County participated in a prostate examination campaign. Targeting these men, we collected the International Prostate Symptom Score (IPSS), medical history, demographic information, serum prostate-specific antigen, and prostate volume as measured by transrectal ultrasonography. The data for 599 participants were analyzed, excluding 180 men who had a possibility of prostate cancer. BPH was defined as an IPSS of 8 points or higher and a prostate volume of 25 mL or more. RESULTS: The prevalence rate of BPH was 20.0%. The prevalence rate increased with age. There were 2 subjects (4.4%) in the age group of 40-49 years, 18 subjects (10.9%) in the age group of 50-59 years, 44 subjects (22%) in the age group of 60-69 years, and 56 subjects (26.6%) in the age group of over 70 years; this increase with age was statistically significant (p<0.001). In the BPH group, the average IPSS was 14.67+/-5.95, the average prostate volume was 37.04+/-11.71 g, and the average prostate-specific antigen value was 1.56+/-0.88 ng/mL. In the analysis of correlations between the epidemiologic factors and the risk of BPH, smoking was the only statistically significant factor. CONCLUSIONS: The total prevalence rate of BPH in this study was 20.0%, which was a little lower than the rate reported in other cities or rural areas.

PURPOSE: Lower urinary tract symptoms (LUTS) comprise a set of common, bothersome symptoms in middle-aged and elderly men. Recent research suggests that depressive symptoms may influence the symptoms of benign prostatic hyperplasia (BPH). We performed a community-based cross-sectional study to evaluate the correlation between LUTS and depression. METHODS: The survey was conducted in a rural community during four periods in August 2009, 2010, 2011, and 2012. Two validated questionnaires were used to examine LUTS and depressive symptoms. These included the International Prostate Symptom Score/quality of life (IPSS/QoL) and the Korean version of the Center for Epidemiological Studies-Depression scale (CES-D-K). Patients were categorized in the depressive symptom group if their CES-D-K score was >16 points. RESULTS: A total of 711 men were included in this study. Thirty-five participants (4.92%) were found to have depressive symptoms. There was a positive correlation between depressive symptoms and LUTS severity (P<0.001). As compared to the mild LUTS group, the odds ratio (OR) of depression was 2.868 (95% confidence interval [CI], 1.293-6.362; P for trend<0.001) in the moderate LUTS group, and 4.133 (95% CI, 1.510-11.313; P for trend<0.001) in the severe LUTS group. In a model considering multiple variables such as age, education level, smoking, and exercise, the OR in the moderate LUTS group was 2.534 (1.125-5.708, 95% CI, P for trend=0.005), while that in the severe LUTS group was 3.910 (95% CI, 5.708-11.154; P for trend=0.005). In addition, depression was related to voiding symptoms. CONCLUSIONS: Men with severe LUTS are at higher risk of depression than those with less severe urinary symptoms. The severity of voiding symptoms worsens depression. More aggressive urological diagnosis and treatment is needed in patients with severe LUTS, due to the impact on depressive symptoms and QoL.

PURPOSE: The number of benign prostatic hyperplasia (BPH) subjects has been increasing worldwide, and many studies have been conducted to determine the treatment that can delay drug therapy or surgery. Subsequently, most of these studies involved physical activity (PA) and associated factors. Therefore, we aimed to determine factors associated with BPH prevalence based on a review of past and present studies and to investigate the effect of a healthy lifestyle as a protective factor of BPH occurrence. METHODS: We selected 582 subjects aged > or =40 years from an initial 779 subjects recruited from Gyeonggi, Yangpyeong, South Korea, during August 2009 to August 2011. Trained investigators surveyed International Prostate Symptom Score and demographic information, including PA and lifestyle questionnaire during face-to-face interviews; further, they performed digital rectal examination, rectal ultrasonography, and measured prostate-specific antigen levels. The statistical association between PA and BPH was analyzed by logistic regression analysis using multivariable regression models which use categorical variables by the Cochran-Mantel-Haenszel test and continuous variables by the general linear model. RESULTS: Seven statistically significant variables for PA were selected. Regular exercise, frequency of exercise, sedentary time, nonsedentary time, leisure time PA (metabolic equivalent, hr/wk) were not statistically associated with prostate volume but sedentary time (hr/day) was the only factor that showed a significant association in the multivariable model, including a linear effect relationship. Subjects with lower levels of sedentary time (4.5-7.0 hr/day) had a significantly lower risk of BPH (odds ratio [OR], 0.93; 95% confidence interval [CI], 0.52-1.67) than those with a higher sedentary time (>7 hr/day) (OR, 1.72; 95% CI, 0.96-3.09) (P for trend=0.05). CONCLUSIONS: Our study showed that reducing sedentary time could have a protective effect and reduce the prevalence of BPH. Further prospective studies with a larger sample size are needed to assess the impact of reducing sedentary time on BPH risk.

OBJECTIVES: Sleep disorders cause changes of autonomic nervous system (ANS) which affect cardiovascular system. Primary insomnia (PI) makes acceleration of sympathetic nervous system (SNS) tone by sleep deficiency and arousal. Obstructive sleep apnea syndrome (OSAS) sets off SNS by frequent arousals and hypoxemias during sleep. We aimed to compare the changes of heart rate variability (HRV) indices induced by insomnia or sleep apnea to analyze for ANS how much to be affected by PI or OSAS. METHODS: Total 315 subjects carried out nocturnal polysomnography (NPSG) were categorized into 4 groups - PI, mild, moderate and severe OSAS. Severity of OSAS was determined by apnea-hypopnea index (AHI). Then we selected 110 subjects considering age, sex and valance of each group's size [Group 1 : PI (mean age=41.50+/-13.16 yrs, AHI 30, n=30)]. Comparison of HRV indices among the four groups was performed with ANCOVA (adjusted for age and body mass index) and Sidak post-hoc test. RESULTS: We found statistically significant differences in HRV indices between severe OSAS group and the other groups (PI, mild OSAS and moderate OSAS). And there were no significant differences in HRV indices among PI, mild and moderate OSAS group. In HRV indices of PI and severe OSAS group showing the most prominent difference in the group comparisons, average RR interval were 991.1+/-27.1 and 875.8+/-22.0 ms (p=0.016), standard deviation of NN interval (SDNN) was 85.4+/-6.6 and 112.8+/-5.4 ms (p=0.022), SDNN index was 57.5+/-5.2 and 87.6+/-4.2 (p<0.001), total power was 11,893.5+/-1,359.9 and 18,097.0+/-1,107.2 ms2 (p=0.008), very low frequency (VLF) was 7,534.8+/-1,120.1 and 11,883.8+/-912.0 ms2 (p=0.035), low frequency (LF) was 2,724.2+/-327.8 and 4,351.6+/-266.9 ms2 (p=0.003). CONCLUSIONS: VLF and LF which were correlated with SNS tone showed more increased differences between severe OSAS group and PI group than other group comparisons. We could suggest that severe OSAS group was more influential to increased SNS activity than PI group.
