Purpose:
This study aimed to investigate the sustained effects of a 3-week equine-assisted activities and therapies (EAAT) program on motor function and muscle activity in children with cerebral palsy (CP).
Methods:
Nine children with CP (aged 5–15 years, Gross Motor Function Classification System stages I–III) parti-cipated in the study. We assessed Gross Motor Function Measure-66 (GMFM-66) scores, Pediatric Balance Scale (PBS) scores, BioRescue static posturography (RM Ingenierie) findings, core-muscle activity, and body composition before, immediately after, and 3 months after EAAT.
Results:
Of the nine included children, eight showed improvement in their GMFM-66 scores and six showed improvement in their PBS scores. No significant changes were observed in GMFM-66 and PBS scores immediately after the EAAT program compared to baseline. However, significant improvements were noted 3 months after EAAT in both GMFM-66 and PBS scores. Trunk skeletal muscle mass showed a significant increase immediately after EAAT. Balance, stability, and muscle activity during the gait cycle remained stable throughout the study.
Conclusion
This study suggests that a short-period EAAT program can lead to long-term improvements in gross motor function for children with CP.

Background/Aims:
Screening for colorectal cancer (CRC) is important in reducing the morbidity and mortality of CRC. Thus, this study aimed to describe the trends of CRC screening in both organized and opportunistic settings in Korea from 2005 to 2020 according to sociodemographic characteristics.
Methods:
This study analyzed the data of adults aged 50 to 74 years from the Korean National Cancer Screening Survey. Trends for CRC screening rates (fecal immunochemical test [FIT] within the last year, double-contrast barium enema within the last 5 years, or colonoscopy within the last 10 years for 2005–2018 and FIT within the last year or colonoscopy within the last 10 years for 2019–2020) were analyzed using Joinpoint regression. The trends were also analyzed according to sociodemographic characteristics, including age, sex, monthly household income, education level, and residential area.
Results:
A total of 29,040 participants were included in the analysis. The CRC screening rate significantly increased from 25.0% to 60.1%, with an annual percent change (APC) of 9.2% between 2005 and 2014, followed by a nonsignificant increase to 64.4% between 2014 and 2020 (APC,1.7%). When the participants were stratified according to sociodemographic factors, the participants with higher household income and education levels generally had higher screening rates.
Conclusions
There has been substantial improvement in CRC screening rates in the general Korean population. However, it is necessary to determine why the screening rate has stabilized since 2014 and identify barriers that cause disparities in CRC screening rates among populations with lower socioeconomic status.

Objective:
This study aimed to analyze the trends in cervical cancer screening rates, including organized and opportunistic cancer screening rates, with the Papanicolaou test among Korean women.
Methods:
Data were collected from a nationwide, cross-sectional, Korean National Cancer Screening Survey. To evaluate the cervical cancer screening rates, we used the screening approach of “cervical cancer screening rate with recommendation,” defined as the proportion of women who underwent the Papanicolaou test during the previous 2 years according to the Protocol of National Cancer Screening Program for Cervical Cancer in Korea. The joinpoint regression analysis, which describes the annual percent change (APC), was performed to detect significant changes in cervical cancer screening rates in women aged 30-74 years during 2005-2020.
Results:
The cervical cancer screening rate was 56.0% in 2020. From 2005 to 2013, there was a rising trend in cervical cancer screening rates (APC=2.70%, 95% confidence interval [CI]:1.05 to 4.38), followed by a falling trend (APC=−2.67%, 95% CI:−4.3 to −1.01). The falling trend was significantly associated with age (≥40 years), education level (below the 15th grade), household income (below the middle-income level), and residence (all residential areas).
Conclusion
The recent falling trend was more common in women with a low socioeconomic status, which suggests that there is a socioeconomic gap in cervical cancer screening. Moreover, young women in their thirties had a low screening rate. Therefore, an active participation strategy for women vulnerable to cervical cancer is required.

Background:
and Purpose: Neural stem cells (NSCs) have the ability to regenerate, proliferate, and differentiate, enabling them to play important roles in the recovery of the damaged nervous system. However, in neurodegenerative diseases such as Alzheimer's disease (AD), the NSCs are damaged as well. Glia-like cells from human mesenchymal stem cells (ghMSCs) are functionally enhanced adult stem cells. In the present study, we investigated whether ghMSCs could protect NSCs from amyloid beta (Aβ)-mediated toxicity.
Methods:
Rat NSCs were obtained from E13–14 fetal rat cortices. NSCs were seeded in pre-coated plates, and the next day, cells were simultaneously treated with 20 μM Aβ and 0.4 μm pore insert well-seeded ghMSCs. After 48 hours of co-treatment, cell viability and proliferation were evaluated. After 2 hours of co-treatment, western blotting was performed to measure inflammasome-related factors, such as NOD-like receptor family pyrin domain containing 3, caspase-1, and interleukin-1β.
Results:
The results showed that ghMSCs increased viability and proliferation and reduced the toxicity of NSCs injured by Aβ by reducing the NRLP3 inflammasome activation of NSCs induced by Aβ.
Conclusions
In this study, we confirmed that ghMSCs could protect NSCs in an in vitro model of AD through the regulation of inflammatory response.

Citrus junos seeds (CS) have been traditionally used for the treatment of cancer and neuralgia. They are also used to manufacture edible oil and cosmetic perfume. A large amount of CS shells without oil (CSS) are discarded after the oil in CS is used as foods or herbal remedy. To efficiently utilize CSS as a by-products, it needs to be studied through chemical analysis. Therefore, we developed an ultra-performance liquid chromatography (UPLC)–diode array detection (DAD) method for simultaneous determination and quantitative analysis of five components (two flavonoids and threes limonoids) in CSS. A Waters Acquity UPLC HSS T3 column C18 (2.1 × 100 mm, 1.8 μm) was used for this separation. It was maintained at 40 oC. The mobile phase used for the analysis was distilled water and acetonitrile with gradient elution. To identify the quantity of the five components, a mass spectrometer (MS) with an electrospray ionization (ESI) source was used. The regression equation showed great linearity, with correlation coefficient ≥ 0.9912. Limits of detection (LOD) and limits of quantification (LOQ) of the five compounds were 0.09 – 0.13 and 0.26 – 0.38 μg/mL, respectively. Recoveries of extraction ranged from 97.45% to 101.91%. Relative standard deviation (RSD) values of intra- and inter-day precision were 0.06 – 1.15% and 0.19 – 0.25%, respectively. This UPLC–DAD method can be validated to simultaneously analyze quantities of marker flavonoids and limonoids in CSS.

Objective:
This study identified the distribution of lymphocele, as well as the factors associated with lymphocele formation, in patients undergoing pelvic and/or para-aortic lymph node dissection (PLND and/or PALND) for gynecologic malignancies.
Methods:
This study was retrospective, and data were collected from patients who underwent surgical procedures including lymphadenectomy due to gynecologic malignancies from March 2013 to May 2016. Lymphocele was defined by postoperative computer tomography within 2 weeks after surgery.
Results:
A total of 116 patients underwent lymphadenectomy, of whom, 47 (42.0%) developed lymphocele and 14 (12.1%) had symptomatic lymphocele formation. The affecting factors of lymphocele formation were PLND concomitant with PALND and a large amount of blood loss ≥600 mL (P=0.030 and P=0.006, respectively). All clinical factors were not significantly different between patients with symptomatic and asymptomatic lymphocele. Lymphocele developed more frequently in the left side (67.1%) of the body compared to the right side (48.7%), and in the pelvic area (75.9%) compared to the para-aortic area (24.1%, P<0.001, both).
Conclusion
Lymphocele formation is more prevalent in the left and pelvic area of the body compared to the right and paraaortic side. PLND concurrent with PALND and large amounts of blood loss were significant risk factors for lymphocele formation.

Objective To investigate the distribution of urinary iodine level and its relationship with thyroid function in Tibetan adults in Lhasa. Methods Tibetan residents living in Lhasa and its surrounding countryside were recruited by the method of multistage randomized cluster sampling. Their salt iodine, drinking water iodine, urinary iodine, and thyroid function levels were detected. According to the urinary iodine level, these subjects were divided into the iodine deficiency group ( urinary iodine<100μg/L) , the iodine enough group ( urine iodine 100-199μg/L) , the iodine adequate group ( urine iodine 200-299 μg/L ) and the iodine excessive group ( urine iodine≥300μg/L) . The differences in thyroid function among various groups were compared. Results A total of 2235 subjects were included in the study. The overall level of urinary iodine was in skewed distribution, with a median ( upper and lower quartiles) of 154 (99, 229) μg/L. The proportion of subjects with insufficient iodine intake was 25.7%, while those of the enough, adequate, and excessive groups were 41. 5%, 21. 3%, and 11. 5%, respectively. There was no significant difference in urine iodine level between males and females [152(95,219)μg/L vs 155(100,232)μg/L P>0.05]. The urinary iodine levels in residents of urban were higher than those in rural residents [157(101,232)μg/L vs 140(92,200)μg/L, P<0.05]. The urinary iodine levels in the young, middle-aged, and elderly groups were 175 ( 116,256) , 136 ( 91, 200) , and 116 ( 68, 164)μg/L respectively, showing a gradual decrease in urine iodine level with aging (P<0.05). The average salt iodine content of Tibetan adults in Lhasa was 23.16 mg/kg, and that in drinking water was 4.33μg/L. There were no significant differences in TSH levels among various iodine intake groups ( P>0.05) . The levels of thyroid peroxidase antibody ( TPOAb) and thyroglobulin antibody ( TGAb) were gradually decreased with the increase of urinary iodine level (P<0.05). Conclusion More than 50% of Tibetans are at the status of low iodine and high iodine intakes in Lhasa. Although the salt iodine content meets national standards, the drinking water iodine content is lower than that standard.

PURPOSE: To investigate the surgical, perfusion, and molecular characteristics of glioblastomas which influence long-term survival after treatment, and to explore the association between MR perfusion parameters and the presence of MGMT methylation and 1p/19q deletions. MATERIALS AND METHODS: This retrospective study was approved by our institutional review board. A total 43 patients were included, all with pathologic diagnosis of glioblastoma with known MGMT methylation and 1p/19q deletion statuses. We divided these patients into long-term (≥ 60 months, n = 7) and short-term (< 60 months, n = 36) survivors, then compared surgical extent, molecular status, and rCBV parameters between the two groups using Fisher's exact test or Mann-Whitney test. The rCBV parameters were analyzed according to the presence of MGMT methylation and 1p/19q deletions. We investigated the relationship between the mean rCBV and overall survival using linear correlation. Multivariable linear regression was performed in order to find the variables related to overall survival. RESULTS: Long-term survivors (100% [7 of 7]) demonstrated a greater percentage of gross total or near total resection than short-term survivors (54.5% [18 of 33]). A higher prevalence of 1p/19q deletions was also noted among the long-term survivors (42.9% [3 of 7]) than the short-term survivors (0.0% [0 of 36]). The rCBV parameters did not differ between the long-term and short-term survivors. The rCBV values were marginally lower in patients with MGMT methylation and 1p/19q deletions. Despite no correlation found between overall survival and rCBV in the whole group, the short-term survivor group showed negative correlation (R2 = 0.181, P = 0.025). Multivariable linear regression revealed that surgical extent and 1p/19q deletions, but not rCBV values, were associated with prolonged overall survival. CONCLUSION: While preoperative rCBV and 1p/19q deletion status are related to each other, only surgical extent and the presence of 1p/19q deletion in GBM patients may predict long-term survival.
