Background:
and Purpose An intracranial vertebral artery dissecting aneurysm (iVADA) increases the risk of future subarachnoid hemorrhage, which is a severe complication with high rebleeding rates and poor outcomes. Identifying potential risk factors associated with iVADA growth is crucial for their effective management.
Methods:
This observational study was carried out at a single center and included patients who had been diagnosed with iVADA based on neuroimaging findings. We divided the patients into two groups: with and without iVADA growth. Growth was defined as any enlargement of a dilated region or a morphological change in follow-up imaging. We measured the vertebral artery tortuosity index (VTI) in the contralateral vertebral artery (VA), defined as its actual length divided by its straight length. We investigated the factors associated with iVADA growth.
Results:
This study included 124 patients. The median follow-up period was 7 months. We observed iVADA growth in 54 patients (43.5%), who were more likely to be current smokers (33.3% vs. 14.3%, p=0.012) and have a higher VTI (1.14±0.11 [mean±standard deviation] vs.1.06±0.12, p=0.035) compared with those without iVADA growth. A multivariate analysis revealed that the VTI (adjusted odds ratio=28.490, 95% confidence interval=1.025–792.046, p=0.048) was independently associated with iVADA growth.
Conclusions
This study has identified an independent association between VA tortuosity and iVADA growth.

Background:
and Purpose This study aimed to investigate the applicability of deep learning (DL) model using diffusion-weighted imaging (DWI) data to predict the severity of aphasia at an early stage in acute stroke patients.
Methods:
We retrospectively analyzed consecutive patients with aphasia caused by acute ischemic stroke in the left middle cerebral artery territory, who visited Asan Medical Center between 2011 and 2013. To implement the DL model to predict the severity of post-stroke aphasia, we designed a deep feed-forward network and utilized the lesion occupying ratio from DWI data and established clinical variables to estimate the aphasia quotient (AQ) score (range, 0 to 100) of the Korean version of the Western Aphasia Battery. To evaluate the performance of the DL model, we analyzed Cohen’s weighted kappa with linear weights for the categorized AQ score (0–25, very severe; 26–50, severe; 51–75, moderate; ≥76, mild) and Pearson’s correlation coefficient for continuous values.
Results:
We identified 225 post-stroke aphasia patients, of whom 176 were included and analyzed. For the categorized AQ score, Cohen’s weighted kappa coefficient was 0.59 (95% confidence interval [CI], 0.42 to 0.76; P<0.001). For continuous AQ score, the correlation coefficient between true AQ scores and model-estimated values was 0.72 (95% CI, 0.55 to 0.83; P<0.001).
Conclusions
DL approaches using DWI data may be feasible and useful for estimating the severity of aphasia in the early stage of stroke.

Background:
This study aimed to investigate the recent prevalence, management, and comorbidities of diabetes among Korean adults aged ≥30 years by analyzing nationally representative data.
Methods:
This study used data from the Korea National Health and Nutrition Examination Survey from 2016 to 2018, and the percentage and total number of people ≥30 years of age with diabetes and impaired fasting glucose (IFG) were estimated.
Results:
In 2018, 13.8% of Korean adults aged ≥30 years had diabetes, and adults aged ≥65 years showed a prevalence rate of 28%. The prevalence of IFG was 26.9% in adults aged ≥30 years. From 2016 to 2018, 35% of the subjects with diabetes were not aware of their condition. Regarding comorbidities, 53.2% and 61.3% were obese and hypertensive, respectively, and 72% had hypercholesterolemia as defined by low-density lipoprotein cholesterol (LDL-C) ≥100 mg/dL in people with diabetes. Of the subjects with diabetes, 43.7% had both hypertension and hypercholesterolemia. With regard to glycemic control, only 28.3% reached the target level of <6.5%. Moreover, only 11.5% of subjects with diabetes met all three targets of glycosylated hemoglobin, blood pressure, and LDL-C. The percentage of energy intake from carbohydrates was higher in diabetes patients than in those without diabetes, while that from protein and fat was lower in subjects with diabetes.
Conclusion
The high prevalence and low control rate of diabetes and its comorbidities in Korean adults were confirmed. More stringent efforts are needed to improve the comprehensive management of diabetes to reduce diabetes-related morbidity and mortality.

Since the human papillomavirus (HPV) vaccine guidelines were developed by the Korean Society of Gynecologic Oncology (KSGO) in 2011, 2016, and 2019, several recent studies on the efficacy and safety of HPV vaccines in middle-aged women and men have been reported. Furthermore, there has been an ongoing debate regarding the efficacy of the HPV vaccine in women with prior HPV infection or who have undergone conization for cervical intraepithelial neoplasia (CIN). We searched and reviewed studies on the efficacy and safety of the HPV vaccine in middle-aged women and men and the efficacy of the HPV vaccine in patients infected with HPV and those who underwent conization for CIN. The KSGO updated their guidelines based on the results of the studies included in this review.

Purpose:
Here, we compared the operative and perioperative outcomes between robot-assisted laparoscopic myomectomy (RALM) and abdominal myomectomy (AM) in patients with large (>10 cm) or heavy myomas (>250 g).
Materials and Methods:
We included 278 patients who underwent multi-port RALM (n=126) or AM (n=151) for large or heavy myomas in a tertiary care hospital between April 2019 and June 2020. The t-test, chi-square, Bonferroni’s test, and multiple linear regression were used.
Results:
No differences were observed in age, body mass index, parity, or history of pelvic surgery between the two groups. Myoma diameters were not different (10.8±2.52 cm vs. 11.2±3.0 cm, p=0.233), but myomas were lighter in the RALM group than in the AM group (444.6±283.14 g vs. 604.68±368.35 g, respectively, p=0.001). The RALM group had a higher proportion of subserosal myomas, fewer myomas, fewer large myomas over >3 cm, lighter myomas, and longer total operating time. However, the RALM group also had shorter hospital stay and fewer short-term complications. Estimated blood loss (EBL) was not different between the two groups. The number of removed myomas was the most significant factor (coefficient=10.89, p<0.0001) affecting the EBL.
Conclusion
RALM is a feasible myomectomy technique even for large or heavy myomas. RALM patients tend to have shorter hospital stays and fewer postoperative fevers within 48 hours. However, RALM has longer total operating time.

Background:
and PurposeA cognitive intervention (CI) is thought to improve cognition and delay cognitive decline via neuronal plasticity and cognitive resilience. Subjective cognitive decline (SCD) might be the first symptomatic stage of Alzheimer's disease, but few studies have examined the beneficial effect of CIs in SCD. We aimed to determine the efficacy of a 12-week, small-group-based, multidomain CI in elderly patients with SCD.
Methods:
Participants diagnosed with SCD (aged 55–75 years) were consecutively allocated to three groups: group 1, which received group-based CI implementation with lifestyle modifications; group 2, which received home-based lifestyle modifications without CI; and group 3, in which no action was taken. The primary outcome variables were the scores on computerized tests of the Cambridge Neuropsychological Test Automated Battery (CANTAB). The secondary outcomes included scores on tests evaluating general cognition, memory, visuospatial, and executive functions, as well as scores for the quality of life (QoL), anxiety, depression, and degree of subjective complaints. Changes in scores during the study period were compared between groups.
Results:
The study was completed by 56 SCD participants. The baseline characteristics did not differ among the groups. The primary outcomes (CANTAB scores) did not differ among the groups. However, the outcomes for phonemic word fluency, verbal memory, QoL, and mood were better for group 1 than for the other two groups. Improvements in verbal memory function and executive function were related to the baseline cognitive scores and group differences.
Conclusions
CI in SCD seems to be partially beneficial for executive function, memory, QoL, and mood, suggesting that CI is a useful nonpharmacological treatment option in this population.

PURPOSE: The purpose of the study is to identify the effects of worker's stair-climbing on blood pressure, lipid profiles, and physical fitness. METHODS: After recruiting 114 healthy adult women aged 20 to 64 years who have had sedentary for more than 3 months, we divided into two groups: the stair group (SG, n=57) and control group (CG, n=57). SG was supposed to do stair-climbing in daily life like workplace and home for 12 weeks. To investigate the effects of the lifestyle changing of stair-climbing, resting blood pressure, heart rate (HR), and lipid profiles were measured before and after 12-week stair-climbing. Also, physical fitness items such as peak oxygen consumption (VO2peak), back muscle strength, sit and reach, isokinetic strength of knee joint, static and dynamic balance were measured. RESULTS: As a result of the 12-week lifestyle changing of stair-climbing, resting systolic blood pressure (SBP; p < 0.05) and HR (p < 0.01) were significantly decreased in SG. Low-density lipoprotein-cholesterol (LDL-C) was significantly reduced in SG (p < 0.05). There was a significant improvement in the VO2peak (p < 0.001). There were a significant improvement in back strength (p < 0.001) and bilateral knee extensor (60°/sec: p < 0.05, p < 0.01, 180°/sec: p < 0.01, p < 0.01) and knee flexor (180°/sec: p < 0.01, p < 0.05) of isokinetic strength. There were significant improvements in static balance of one leg standing eye-closed (p < 0.05) and dynamic balance of left/right velocity (p < 0.01), forward/backward velocity (p < 0.01). CONCLUSION: In this study, 12 weeks of lifestyle changing of stair-climbing improved SBP, resting HR, LDL-C, VO2peak, back and knee strength, static and dynamic balance as well as increased physical activity volume of stair-climbing in the daily living.
