Abstract
(1) Background: The lymphocyte-to-monocyte ratio (LMR), one of the systemic inflammatory markers, has been shown to be associated with prognosis of various solid tumors. However, no study has reported clinical utility of the LMR of malignant body fluid (mLMR) (2) Methods: We retrospectively analyzed clinical data of the final 92 patients of a total of 197 patients with advanced ovarian cancer newly diagnosed from November 2015 and December 2021 using our institute big data. (3) Results: Patients were divided into three groups according to their combined bLMR and mLMR scores (bmLMR score): 2, both bLMR and mLMR were elevated; 1, bLMR or mLMR was elevated; and 0, neither bLMR nor mLMR was elevated. A multivariable analysis confirmed that the histologic grade (p = 0.001), status of residual disease (p < 0.001), and bmLMR score (p < 0.001) were independent predictors of disease progression. A low combined value of bLMR and mLMR was strongly associated with a poor prognosis in patients with ovarian cancer. (4) Conclusions: Although further studies are required to apply our results clinically, this is the first study to validate the clinical value of mLMR for predicting prognosis of patients with advanced ovarian cancer.

Abstract
Introduction We aimed to evaluate the efficacy and toxicity of the combination of 6 cycles of chemotherapy and radiation therapy compared with chemotherapy alone as postoperative adjuvant therapy for patients with stage III endometrial cancer. Methods This retrospective cohort study included patients with stage III endometrial cancer who received postoperative chemoradiotherapy or chemotherapy alone at 6 hospitals between January 2009 and December 2019. The progression-free survival (PFS) and overall survival (OS) for each treatment group were analyzed using the Kaplan–Meier method. We also assessed differences in toxicity profiles between the treatment groups. Results A total of 133 patients met the inclusion criteria. Of these, 80 patients (60.2%) received adjuvant chemoradiotherapy and 53 (39.8%) received chemotherapy alone. The PFS and OS did not differ significantly between the groups. For patients with stage IIIC endometrioid subtype, the chemoradiotherapy group had significantly longer PFS rate than did the chemotherapy alone group (log-rank test, P = .019), although there was no significant difference in the OS (log-rank test, P = .100). CRT was identified as a favorable prognostic factor for PFS in multivariate analysis (adjusted HR, .37; 95% CI, .16-.87; P = .022). Patients treated with chemoradiotherapy more frequently suffered from grade 4 neutropenia (73.8% vs 52.8%; P = .018) and grade 3 or worse thrombocytopenia (36.3% vs 9.4%; P = .001) compared with the chemotherapy alone group. There were no differences between the 2 treatment groups in the frequency of toxicity-related treatment discontinuation or dose reduction. Conclusion We confirmed that chemoradiotherapy yields longer progression-free survival than does chemotherapy alone for patients with stage IIIC endometrioid endometrial cancer, with an acceptable toxicity profile.

Abstract
Abstract
Background - Despite preventive HPV vaccines is implemented worldwide, current treatments for high grade cervical intraepithelial neoplasia are ablative, and no pharmacological treatments are available. Here we evaluated safety of BLS-ILB-E710c, HPV 16 E7-expressing Lactobacillus-based vaccine, and explored its efficacy for histopathological regression in women with CIN2/3. Methods - Safety and efficacy of BLS-ILB-E710c were assessed in CIN2/3 associated with HPV16 and its related HPV types in a randomized, double-blind, placebo-controlled phase 2b study. Total of 116 patients was recruited from fourteen hospitals in South Korea, and were randomized (2:1) to receive 1000 mg BLS-ILB-E710c or placebo for 5 days at 1, 2, 4, and 8 weeks. The primary endpoint was histopathological regression to CIN1 or normal pathology at 16 weeks after the first dose. Full analysis set (FAS) and Per-protocol set (PPS) analyses were based on patients receiving at least one oral vaccination, and on patients receiving four rounds of oral vaccination without protocol violations, respectively. The safety population included all patients who enrolled. The trial is registered at clinicaltrials.gov (number NCT03274206). Findings - Total of 116 patients were randomized, and 113 received either BLS-ILB-E710c (n=75) or placebo (n=38). The oral vaccination was well tolerated and no serious vaccine-related AEs occurred. No differences were showed between the BLS-ILB-E710c and placebo groups for patient background and adverse events. In the full analysis set (FAS) no statistically significant difference was noted between the two groups of histopathological regression at 16 weeks. However, the distribution by Bethesda system (for cervical cytology) in CIN2 patients showed significant differences between two groups (P=0.0304), which can affect histopathological regression. Sub-group analysis in FAS is performed to reduce the bias; histopathological classification (CIN2, CIN3) and cytological classification (≤ASCUS, LSIL, HISL). Therefore, in CIN3 sub-group, BLS-ILB-E710c recipients showed 13.33% of higher histopathological regression at 32 weeks than placebo recipients, and interestingly represented the statistically significant difference when histopathological regression at 32 weeks compared with 16 weeks (percentage point difference 34.87 [95% CI 7.78–61.96]; P=0.0216). In BLS-ILB-E710c recipients of CIN3 sub-group with histopathological regression, E7-specific CD8+ T lymphocyte immune responses were induced at 32 weeks (P= 0.0323). In addition, in HSIL sub-group, BLS-ILB-E710c recipients showed higher histopathological regression at 32 weeks than placebo recipients in similar with CIN3 sub-group analysis. Interpretation – Based on the finding this study, BLS-ILB-E710c could induce the local immune response by recruiting HPV16 E7-specific CD8+ T cells to cervical lesions, leading to histologic regression. To assess the efficacy of BLS-ILB-E710c as a novel Lactobacillus-based oral vaccine, it is necessary to define the population and time frame for phase 3 trial.

Abstract
BACKGROUND National human papillomavirus (HPV) vaccination programs could reduce global cervical cancer morbidity and mortality with support from health care providers. We assessed providers' perceptions of HPV vaccination in 5 countries. METHODS We identified providers from 5 countries where national HPV vaccination programs were at various stages of implementation: Argentina, Malaysia, South Africa, South Korea, and Spain. Providers authorized to administer adolescent vaccines completed an in-depth survey, reporting perceptions of barriers and facilitators to initiating and completing HPV vaccination, and logistical challenges to HPV vaccination. RESULTS Among 151 providers, common barriers to HPV vaccination initiation across all countries were parents' lack of awareness (39%), concerns about vaccine safety or efficacy (33%), and cost to patients (30%). Vaccination education campaign (70%) was the most commonly cited facilitator of HPV vaccination initiation. Common barriers to series completion included no reminder system or dosing schedule (37%), loss to follow-up or forgetting appointment (29%), and cost to patients (25%). Cited facilitators to completing the vaccine series were education campaigns (45%), affordable vaccination (32%), and reminder/recall systems (22%). Among all countries, high cost of vaccination was the most common logistical challenge to offering vaccination to adolescents (33%). CONCLUSIONS Incorporating provider insights into future HPV vaccination programs could accelerate vaccine delivery to increase HPV vaccination rates globally.

Abstract
Cancer treatment options have evolved to include immunotherapy and targeted therapy, in addition to traditional chemoradiation. Chemoradiation places the patient at a higher risk of infection through a myelosuppressive effect. High clinical suspicion and early use of antimicrobials play a major role in decreasing any associated morbidity and mortality. This has led to a widespread use of antimicrobials in cancer patients. Antimicrobial use, however, does not come without its perils. Dysbiosis caused by antimicrobial use affects responses to chemotherapeutic agents and is prognostic in the development and severity of certain cancer treatment-related complications such as graft-versus-host disease and Clostridioides difficile infections. Studies have also demonstrated that an intact gut microbiota is essential in the anticancer immune response. Antimicrobial use can therefore modulate responses and outcomes with immunotherapy targeting immune checkpoints. In this review, we highlight the perils associated with antimicrobial use during cancer therapy and the importance of a more judicious approach. We discuss the nature of the pathologic changes in the gut microbiota resulting from antimicrobial use. We explore the effect these changes have on responses and outcomes to different cancer treatment modalities including chemotherapy and immunotherapy, as well as potential adverse clinical consequences in the setting of stem cell transplant.

Abstract
Objective: Compare the oncologic outcomes of patients with advanced stage endometrial cancer who were staged by minimally invasive surgery with the outcomes of patients who underwent open surgery. Methods: Data from 138 patients with advanced stage endometrial cancer who were treated between January 2009 and January 2019 were reviewed. The patients' data were retrieved from five institutions. The patients were divided into two groups: those who underwent open surgery and those who underwent minimally invasive surgery. Tumor characteristics, recurrence rate, disease-free survival, and overall survival were compared according to surgical approach. Results: Among the 138 patients included in this study, 72 underwent open surgery (52.2%) and 66 underwent MIS (47.8%). In patients with advanced-stage endometrial cancer, the recurrence rate was significantly higher among those who underwent open surgery (43.1% vs. 25.8%, p = 0.033). Patients with advanced-stage endometrial cancer who underwent open surgery had a significantly lower disease-free survival (p = 0.029) than those who underwent minimally invasive surgery, however, the overall survival (p = 0.051) was similar between the two groups. Conclusion: Minimally invasive surgery showed better survival outcomes when compared to open surgery in advanced-stage EC patients irrespective of the histologic type.

Abstract
Background: Recent studies have demonstrated that the tumor microenvironment, known to be influenced by inflammatory cells, plays a crucial role in cancer progression and clinical outcome of patients. The objective of the present study was to investigate prognostic values of preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) for disease-free survival (DFS) and overall survival (OS) of uterine sarcoma patients. Methods: Ninety-nine patients with uterine sarcoma treated in eight multicenter institutions over the last 20 years were retrospectively analyzed. Curves of DFS and OS were calculated using the Kaplan–Meier method, and univariate and multivariate analyses of various prognostic factors were performed using a Cox proportional hazard regression model. Results: High NLR was significantly associated with worse DFS (p = 0.007) and OS (p = 0.039). Advanced stage (p = 0.017) and high mitotic index (p = 0.036) retained their prognostic significance for DFS. Other clinical variables, including PLR, CA125, and lactate dehydrogenase (LDH) failed to show significant impact. Conclusions: Our findings showed that an elevated preoperative NLR was associated with poor clinical outcome in uterine sarcoma patients. Our results suggest that high NLR in early-stage uterine sarcoma patients might indicate that such patients need more intensive treatments.

TB patients were identified using International Classification of Diseases, Tenth Revision coding (A15-19, U88.0-88.1) and the type of anti-TB drug(s) between 2003 and 2016. Long-term mortality and causes of death in TB patients were analysed.RESULTS: A total of 357 211 individuals had TB over the period from 2003 to 2016 and 103 682 died. The mean age of the cohort was 54.7 ± 20.7 years, and 59.8% were male. The survival probability of TB patients at 1, 5, and 10 years after diagnosis was 87.8%, 75.3%, and 63.3%, respectively. High mortality and TB-related death rates were especially prominent in the early stages after TB diagnosis. The overall standardized mortality ratio of TB patients to the general Korean population was 3.23 (95% confidence interval 3.21-3.25).CONCLUSION: Mortality in TB patients was especially high in the early stages of disease after TB diagnosis, and mostly due to TB. This figure was approximately three-times higher than the mortality rate in the general population.

Abstract
BACKGROUND AND PURPOSE MR imaging is not routinely used to image the extracranial facial nerve. The purpose of this study was to determine the extent to which this nerve can be visualized with a CISS sequence and to determine the feasibility of using that sequence for locating the nerve relative to tumor. MATERIALS AND METHODS Thirty-two facial nerves in 16 healthy subjects and 4 facial nerves in 4 subjects with parotid gland tumors were imaged with an axial CISS sequence protocol that included 0.8-mm isotropic voxels on a 3T MR imaging system with a 64-channel head/neck coil. Four observers independently segmented the 32 healthy subject nerves. Segmentations were compared by calculating average Hausdorff distance values and Dice similarity coefficients. RESULTS The primary bifurcation of the extracranial facial nerve into the superior temporofacial and inferior cervicofacial trunks was visible on all 128 segmentations. The mean of the average Hausdorff distances was 1.2 mm (range, 0.3-4.6 mm). Dice coefficients ranged from 0.40 to 0.82. The relative position of the facial nerve to the tumor could be inferred in all 4 tumor cases. CONCLUSIONS The facial nerve can be seen on CISS images from the stylomastoid foramen to the temporofacial and cervicofacial trunks, proximal to the parotid plexus. Use of a CISS protocol is feasible in the clinical setting to determine the location of the facial nerve relative to tumor.

Abstract
Abstract
Introduction
Given the complexity of left atrial appendage (LAA) structure, current 2D based LAA occluder (LAAO) size prediction system using transesophageal echocardiography (TEE) has limitations.
Objective
To assess the accuracy of LAAO size determination method by implantation simulation using a 3D printed model compared with a conventional method based on TEE.
Methods
We retrospectively reviewed 57 cases with percutaneous LAAO using Amplatzer Cardiac Plug and Amulet from 2014 to 2018. We excluded cases without cardiac CT (21 cases) or with peri-device leakage or inappropriate position of the device on six months follow up TEE (6 cases), or with paroxysmal atrial fibrillation (2 cases). We finally included 28 cases with anatomically and physiologically properly implanted LAAO, using the final size of the implanted devices as a standard for the size prediction accuracy. We generated 3D printing model from cardiac CT images. LAAO size was determined with device implantation simulation using 3D printing model and occluder devices (Figure C), and conventional 2D TEE measurements by two experienced cardiologists who were blinded to the size of the finally implanted device.
Results
The accuracy in size of 3D printed left atrium (LA) models, compared with CT image sources, were validated by measuring the distance between artifacts which were intentionally implanted to LA model during image processing. There was minimal bias (−0.11 mm) between 3D images and printed LA models (Figure A). As plotted in Figure B, LAAO sizing by implantation simulation with 3D printing model showed excellent agreement with actually implanted LAAO size (r=0.927; bias=0.7±2.5), while LAAO sizing by 2D TEE measurements remained poor (r=0.544; bias 2.3±6.7).
Conclusions
LAAO size determination by using 3D printing model of LAA showed excellent accuracy. A prospective study to evaluate the clinical utility of this method should be done in future.

Abstract
Purpose: To examine provider knowledge of HPV vaccination age guidelines in five countries. Methods: A total of 151 providers of adolescent vaccinations in Argentina, Malaysia, South Africa, South Korea, and Spain were interviewed between October 2013 and April 2014. Univariate analyses compared providers' understanding of recommended age groups for HPV vaccination to that of each country's national guidelines. Results: In three of five countries surveyed, most providers (97% South Africa, 95% Argentina, 87% Malaysia) included all nationally recommended ages in their target age group. However, a relatively large proportion of vaccinators in some countries (83% Malaysia, 55% Argentina) believed that HPV vaccination was recommended for women above age 26, far exceeding national guidelines, and beyond the maximum recommended age in the United States. National median minimum and maximum age recommendations cited by the respondents for HPV vaccination were 11 and 29 years in Argentina (national guideline: 11-14), 13 and 48 years in Malaysia (guideline 13-14), 8 and 14 years in South Africa (guideline 9-14), 10 and 20 years in South Korea (guideline 11-14), and 11 and 12 years in Spain (guideline 11-14). In all countries, a higher percentage of vaccinators included all nationally recommended ages for vaccination, as compared to providers who did not administer HPV vaccination. Conclusions: Overall, a substantial proportion of providers incorrectly reported their country's age guidelines for HPV vaccination, particularly the upper age limit. As provider recommendation is among the strongest predictors of successful vaccination uptake among adolescents, improved education and clarification of national guidelines for providers administering HPV vaccination is essential to optimize prevention of infection and associated disease.

Abstract
OBJECTIVE Strong persuasive messaging by providers is a key predictor for patient acceptance of prophylactic human papillomavirus vaccination. We aimed to determine optimal messaging to promote human papillomavirus adolescent vaccination across different geographical sites. METHODS Adolescent providers (n = 151) from Argentina, Malaysia, South Africa, South Korea, and Spain were surveyed on messages, family decision makers, and sources of communication to best motivate parents to vaccinate their adolescent daughters overall, and against human papillomavirus. Multivariate logistic regression assessed the likelihood of recommending messages specifically targeted at cervical cancer with providers' characteristics: gender, medical specialization, and previous administration of human papillomavirus vaccination. RESULTS Mothers were considered the most important human papillomavirus vaccination decision makers for their daughters (range 93%-100%). Television was cited as the best source of information on human papillomavirus vaccination in surveyed countries (range 56.5%-87.1%), except Spain where one-on-one discussions were most common (73.3%). Prevention messages were considered the most likely to motivate parents to vaccinate their daughters overall, and against human papillomavirus, in all five countries (range 30.8%-55.9%). Optimal messages emphasized cervical cancer prevention, and included strong provider recommendation to vaccinate, vaccine safety and efficacy, timely vaccination, and national policy for human papillomavirus vaccination. Pediatricians and obstetricians/gynecologists were more likely to cite that the best prevention messages should focus on cervical cancer (OR: 4.2, 95% CI: 1.17 to 15.02 vs other medical specialists). CONCLUSIONS Provider communication messages that would motivate parents to vaccinate against human papillomavirus were based on strong recommendation emphasizing prevention of cervical cancer. To frame convincing messages to increase vaccination uptake, adolescent providers should receive updated training on human papillomavirus and associated cancers, while clearly addressing human papillomavirus vaccination safety and efficacy.

Abstract
STUDY OBJECTIVE To assess adolescent health care providers' recommendations for, and attitudes towards human papillomavirus (HPV) vaccination in 5 countries. DESIGN In-depth interviews of adolescent health care providers, 2013-2014. SETTING Five countries where HPV vaccination is at various stages of implementation into national programs: Argentina, Malaysia, South Africa, South Korea, and Spain. PARTICIPANTS Adolescent health care providers (N = 151) who had administered or overseen provision of adolescent vaccinations (N = Argentina: 30, Malaysia: 30, South Africa: 31, South Korea: 30, Spain: 30). MAIN OUTCOME MEASURES Frequency of HPV vaccination recommendation, reasons providers do not always recommend the vaccine and facilitators to doing so, comfort level with recommending the vaccine, reasons for any discomfort, and positive and negative aspects of HPV vaccination. RESULTS Over half of providers 82/151 (54%) recommend HPV vaccination always or most of the time (range: 20% in Malaysia to 90% in Argentina). Most providers 112/151 (74%) said they were comfortable recommending HPV vaccination, although South Korea was an outlier 10/30 (33%). Providers cited protection against cervical cancer 124/151 (83%) and genital warts 56/151 (37%) as benefits of HPV vaccination. When asked about the problems with HPV vaccination, providers mentioned high cost 75/151 (50% overall; range: 26% in South Africa to 77% in South Korea) and vaccination safety 28/151 (19%; range: 7% in South Africa to 33% in Spain). Free, low-cost, or publicly available vaccination 59/151 (39%), and additional data on vaccination safety 52/151 (34%) and efficacy 43/151 (28%) were the most commonly cited facilitators of health provider vaccination recommendation. CONCLUSION Interventions to increase HPV vaccination should consider a country's specific provider concerns, such as reducing cost and providing information on vaccination safety and efficacy.

Abstract
PURPOSE The World Health Organization revised its human papillomavirus (HPV) vaccination recommendations to include a two (2-) dose schedule for girls aged ≤ 15 years. We investigated acceptability of 2- versus 3-dose schedule among adolescent vaccination providers and mothers of adolescent girls in five countries. METHODS Adolescent vaccination providers (N = 151) and mothers of adolescent girls aged 9-14 years (N = 118) were recruited from Argentina, Malaysia, South Africa, South Korea, and Spain. We assessed providers' preference for a 2- versus 3-dose HPV vaccination schedule via quantitative surveys. Mothers' attitudes towards a 2-dose schedule were assessed through focus group discussions. RESULTS Most adolescent providers preferred a 2- over a 3-dose HPV vaccination schedule (overall: 74%), with preference ranging from 45.2% (South Africa) to 90.0% (South Korea). Lower cost, fewer clinic visits, and higher series completion were commonly cited reasons for 2-dose preference among providers and mothers. Safety and efficacy concerns were commonly cited barriers to accepting a 2-dose HPV vaccination schedule among providers and mothers. Mothers generally accepted the reduced schedule, however requested further information from a trusted source. CONCLUSIONS Adolescent vaccination providers and mothers preferred the 2-dose over 3-dose HPV vaccination schedule. Acceptability of a 2-dose HPV vaccination could be improved with additional information to providers and mothers on HPV vaccination safety and efficacy.

Abstract
PURPOSE Several studies have evaluated the effects of growth hormone (GH) on auxological and biochemical parameters in children with non-GH-deficient, idiopathic short stature (ISS). This study evaluated the efficacy and safety of Growtropin®-II (recombinant human GH) in Korean patients with ISS. METHODS This was a 1-year, open-label, multicenter, phase III randomized trial of Growtropin®-II in Korean patients with ISS. In total, 70 prepubertal subjects (39 males, 31 females) between 4 and 12 years of age were included in the study. All patients were naive to GH treatment. RESULTS Annual height velocity was significantly higher in the treatment group (10.68 ± 1.95 cm/year) than the control group (5.72 ± 1.72, p < 0.001). Increases in height and weight standard deviation scores (SDSs) at 26 weeks were 0.63 ± 0.16 and 0.64 ± 0.46, respectively, for the treatment group, and 0.06 ± 0.15 and 0.06 ± 0.28, respectively, for the control group (p < 0.001). Serum insulin-like growth factor (IGF-1) and insulin-like growth factor binding protein-3 (IGFBP-3) increased significantly in the treatment group at week 26 compared to baseline. However, the SDS for body mass index (BMI) at 26 weeks did not change significantly in either group. Growtropin®-II was well tolerated and safe over 1 year of treatment. CONCLUSIONS One-year GH treatment for prepubertal children with ISS demonstrated increased annualized velocity, height and weight SDSs, and IGF-1 and IGFBP-3 levels, with a favorable safety profile. Further evaluations are needed to determine the optimal dose, final adult height, and long-term effects of ISS treatment.

Abstract
PURPOSE To compare surgical outcomes and complications of 334 women who underwent total laparoscopic hysterectomy with or without the use of barbed sutures for vaginal cuff closure. METHODS A retrospective study was conducted on a cohort of women who underwent total laparoscopic hysterectomy for benign gynecologic diseases at Dae-Jeon St. Mary's Hospital, between May 2009 and May 2016. Surgical outcomes and complications were compared between the two groups. RESULTS A total of 334 women were included: 212 cases of vaginal cuff suture performed with traditional suture material and 122 cases of vaginal cuff suture performed with the barbed suture. No difference in major complications including vaginal bleeding and vaginal cuff dehiscence was found between the two groups, with a significant reduction in operative times for the barbed suture group (P = 0.002). Underlying clinical variables including diabetes, pelvic adhesion, and obesity showed no significant differences in complication rate. CONCLUSION Vaginal cuff suture performed with barbed suture material is a safe and well-tolerated procedure and reduces operative times. We did not find any meaningful decrease in postoperative vaginal complications including vaginal cuff dehiscence based on the suture material.

Abstract
UNLABELLED To evaluate a possible correlation between bone mineral density (BMD) and age at menarche, the present study used the BMD dataset of the Korea National Health and Nutrition Examination Survey IV-V (KNHANES IV-V). Age at menarche had a small but significant association with BMD of the lumbar spine in premenopausal Korean females, aged 20-50 years. INTRODUCTION To investigate any correlation between bone mineral density (BMD) and age at menarche in Korean females using data from the fourth and fifth Korea National Health and Nutrition Examination Survey (KNHANES IV-V; 2008-2011). METHODS In total, 37,753 individuals participated in health examination surveys between 2008 and 2011. A total of 5032 premenopausal females aged 20-50 years were eligible. Age, height, weight, and age at menarche were assessed. RESULTS Results from the univariate linear regression and analysis of covariance (ANCOVA) indicated that age (per 1 year), height (per 1 cm), weight (per 1 kg), exercise (per 1 day/week), familial osteoporosis history (yes), parity (n = 0 to ≥4), and menarche age distribution were associated with BMD of the total femur, femur neck, and lumbar spine. After stratifying the bone area and adjusting for age, parity, alcohol intake, smoking, exercise, and familial osteoporosis history, no effect was seen for the total femur or femur neck. Age at menarche 16~17 and ≥18 years groups were associated with BMD of the lumbar spine only. CONCLUSIONS Age at menarche had a small but significant association with BMD of the lumbar spine in premenopausal Korean females, aged 20-50 years. Females with late menarche may achieve lower peak bone mass at some skeletal sites, which may put them at greater risk for osteoporosis in later life.

Abstract
OBJECTIVES Despite the possibility of early detection of cervical cancer, participation in screening programmes among young Koreans is low. We sought to identify associations between risk factors and participation in screening for cervical cancer among young Koreans. DESIGN Nationwide cross-sectional study. SETTING Republic of Korea. PARTICIPANTS 3734. MAIN OUTCOME MEASURES The Korea National Health and Nutrition Examination Survey (KNHANES V: 2010-2012) was used to evaluate factors associated with attendance for cervical cancer screening among women aged 15-39. After excluding those who were previously diagnosed with cervical cancer and those with incomplete responses to questionnaires, a total of 3734 subjects were eligible. Multi-dimensional covariates as potential predictors of cervical cancer screening were adjusted in multiple logistic regression analysis. RESULTS The participation rate for cervical cancer screening was 46% among women aged 40 or younger. The logistic analyses showed that age, education, total household income, smoking and job status among women aged 15-39 were associated with participation in cervical cancer screening (p<0.05). After age stratification, the associated factors differed by age groups. Moreover, a dose-response between participation in cervical cancer screening and high total household income in the 30-39 age group was seen. CONCLUSIONS Predictive factors differed among young women (aged 15-29 vs 30-39). Thus, age-specific tailored interventions and policies are needed to increase the participation rate in screening for cervical cancer.

Abstract
The present authors describe an uncommon case of iatrogenic bladder stone formation in a patient who underwent surgery for pelvic organ prolapse. A female patient who underwent high uterosacral ligament suspension ten years ago presented with pyuria and irritable bladder symptoms that did not respond to treatment. She had not experienced any specific urinary symptoms during the previous ten years. Patient evaluation revealed bladder stone formation on the non-absorbable suture material used during the previous operation. Cystoscopy during the previous operation did not find the suture material, and the suture knot that was tied extravesically during the operation was found inside the bladder. These strongly suggest delayed migration and rotation of the'suture knot after surgery rather than direct penetration of the bladder during operation. Delayed suture migration is a long-term complication that clinicians should consider in a patient who suffers from recurrent urinary symptoms after pelvic surgery around the bladder.

Abstract
Intestinal inflammation induced with dextran sodium sulfate (DSS) is used to study acute or chronic ulcerative colitis in animal models. Decreased gut tissue anti-inflammatory cytokine IL-10 concentration and mRNA abundance are associated with the development of chronic bowel inflammation. Twelve piglets of 3 days old were fitted with an intragastric catheter and randomly allocated into control and DSS groups by administrating either sterile saline or 1.25 g of DSS/kg body weight (BW) in saline per day, respectively, for 10 days. Growth rate and food conversion efficiency were reduced (p<0.05) in the DSS piglets compared with the control group. Quantitative histopathological grading of inflammation in the jejunum and colon collectively showed that the DSS treatment resulted in 12 fold greater (p<0.05) inflammation severity scoring in the colon than in the jejunum, indicative of chronic ulcerative colitis in the colon. Upper gut permeability endpoint was 27.4 fold higher (p<0.05) in the DSS group compared with the control group. The DSS group had higher concentrations and mRNA abundances (p<0.05) of TNF-alpha and IL-6 in the jejunal and colonic tissues compared with the control group. Colonic concentration and mRNA abundance of IL-10 were reduced (p<0.05), however, jejunal IL-10 mRNA abundance was increased (p<0.05) in the DSS group compared with the control group. In conclusion, administration of DSS at 1.25 g/kg BW for 10 days respectively induced acute inflammation in the jejunum and chronic inflammation and ulcerative colitis in the colon with substantially decreased colonic concentration and mRNA abundance of IL-10 in the young pigs, mimicking the IL-10 expression pattern in humans Associated with chronic bowel inflammation.

Abstract
Cefazolin treatment failure has been observed in high-inoculum infections caused by methicillin-susceptible Staphylococcus aureus (MSSA) with a cefazolin inoculum effect (CIE). However, data on the characteristics and risk factors for the acquisition of CIE-positive MSSA infection are scarce. CIE positivity was measured as an MIC ≥ 16 μg/ml with a high inoculum (∼5 × 107 CFU/ml). The blaZ gene type was assessed through sequence analysis. The clinical characteristics and risk factors for the acquisition of CIE-positive MSSA infection were assessed. The association between the antimicrobial susceptibility profile and CIE positivity was evaluated. A total of 303 MSSA bacteraemia cases and their corresponding isolates were collected from ten hospitals: 61 (20.1 %) isolates showed a positive CIE; 254 (83.8 %) were positive for the blaZ gene. No significant association was found between CIE positivity and the site of infection. Metastatic cancer (aOR 2.86, 95 % CI, 1.10-7.48) and recent (≤1 month) close contact with a chronically ill patient (aOR 4.69, 95 % CI, 1.76-12.50) were identified as significant risk factors for CIE-positive MSSA infection through multivariate analyses. Resistances to clindamycin (OR 3.55, 95 % CI, 1.62-7.80) and erythromycin (OR 5.00, 95 % CI, 2.50-9.99) were associated with CIE positivity, presenting high specificity (92.9 %) and a negative predictive value (82.3 %). CIE-positive MSSA constituted approximately one-fifth of MSSA bacteraemia cases. Although CIE positivity was not clinically discernible, CIE positivity was associated with clindamycin or erythromycin susceptibility. Therefore, our findings suggest that cefazolin can be used in the treatment of high-inoculum MSSA infection if the isolates are susceptible to clindamycin or erythromycin.

Abstract
INTRODUCTION The objective of this study was to investigate whether caffeine intake is associated with urinary incontinence (UI) and quality of life (QOL) in Korean postmenopausal women. MATERIALS AND METHODS We included 4,028 postmenopausal women who had participated in the Korea National Health and Nutrition Examination Survey IV (KNHANES IV). From the KNHANES questionnaire data, we ascertained the UI status of participants, defined as self-reported or medically diagnosed UI, and calculated their total daily caffeine intake through questions regarding the frequency of food consumption. The EuroQoL-5 Dimension (EQ-5D) descriptive system was used to evaluate QOL among the study population. RESULTS The mean age of the study population was 63.19±0.25 years. Among the 4,028 women, the prevalence of medically diagnosed UI was 2.6% (n = 151), the prevalence of self-reported UI was 11.9% (n = 483), and the lifetime prevalence of UI was 15.8% (n = 639). In the study population, the presence of UI was not significantly different by age group, but daily caffeine consumption and the percentage of caffeine consumer decreased with age (P<0.001). Higher caffeine intake led to significantly higher prevalence of both medically diagnosed UI (p = 0.012) and self-reported UI (p = 0.040) in the study population. Even after adjusting for factors including age, parity, smoking status, hypertension and diabetes in logistic regression analysis, the positive association between caffeine intake and UI prevalence was observed in both medically diagnosed UI and self-reported UI (P = 0.017) among participants. In a subgroup analysis for EQ-5D (using continuous variables) in which we categorized participants into four groups according to UI presence and caffeine consumption, the EQ-5D scores were lower in the caffeine non-user group with UI than in the caffeine consumer group with or without UI. CONCLUSION In a sample of Korean postmenopausal women, the prevalence of UI increased with higher caffeine consumption. Additionally, QOL was lower in caffeine non-users with UI than in the caffeine consumer groups. However, additional prospective studies are required to identify clear causation between caffeine consumption, UI prevalence and QOL.

Abstract
BACKGROUND AND OBJECTIVE A recent FDA safety communication has discouraged the use of a power morcellator for myoma extraction and has called for a change in surgical techniques for myomectomy. The objective of this study was to compare surgical outcomes of laparoscopic single-, two-, and conventional three-port myomectomy and to evaluate the feasibility of contained manual morcellation for uterine myoma. METHODS This retrospective study was a review and analysis of data from 191 consecutive women who underwent single-, two-, or three-port myomectomy for the management of uterine myoma from January 1, 2009, through December 31, 2014. RESULTS The 3 study groups did not differ demographically. Apart from operative time, the single- and two-port groups showed operative outcomes comparable to those of the multiport group. The single-port group had significantly longer operative times (P = .0053) than the two- and three-port groups. However, in the latter half of the single-port cases, the operative time was similar to those in the three-port group. The two-port surgery group showed a consistent operative time without a learning period. CONCLUSION Single- or two-port myomectomy with transumbilical myoma morcellation is feasible and safe, with outcomes comparable to those of three-port myomectomy. These results suggest the potential for minimally invasive management of symptomatic uterine myoma, without the use of a power morcellator.

Abstract
PURPOSE To compare surgical outcomes and complications of 284 patients who had total abdominal hysterectomy (TAH), 366 patients who had multi-port access total laparoscopic hysterectomy (MPA-TLH), and 286 patients who had single-port access total laparoscopic hysterectomy (SPA-TLH) using a transumbilical single-port system. METHODS A retrospective study was conducted on a cohort of women who underwent TAH, MPA-TLH, or SPA-TLH for benign gynecologic diseases at DaeJeon St. Mary's Hospital, between January 2003 and December 2013. Surgical outcomes and complications were compared between the three groups. RESULTS The total operative time (min) was longest in the SPA-TLH group (188.3 ± 51.3), followed by the TAH (176.4 ± 47.9) and MPA-TLH (149.3 ± 59.5) groups (p < 0.05). The estimated blood loss (mL) did not differ between MPA-TLH and SPA-TLH (163.8 ± 168.9 vs. 176.9 ± 197.8 mL), but it was the greatest in TAH (427.1 ± 250.6, p < 0.05). The weight of the uterus (gm) was highest in TAH (375.8 ± 380.1, p < 0.05) and similar in MPA-TLH and SPA-TLH (10.1 ± 2.6 vs. 9.7 ± 2.6 cm). The hospital stay (days) was longest in the TAH (7.0 ± 2.1) and SPA-TLH (6.3 ± 2.0) groups, followed by the MPA-TLH (5.5 ± 2.0) group (p < 0.05). The major complication rate was 2.5 % (7 cases) in the TAH group, 5.5 % (20 cases) in the MPA-TLH group, and 0.7 % (2 cases) in the SPA-TLH group. In the MPA-TLH group, the complication rate of the first half of the cases was significantly higher than in the latter half of cases, especially with regards to vaginal cuff dehiscence (p < 0.05). In the SPA-TLH group, no statistically significant difference was found between the two sub-groups. CONCLUSIONS Our study showed that MPA-TLH and SPA-TLH were feasible and safe when compared to TAH. Furthermore, after acquiring technical skills in laparoscopic surgery, conversion from MPA-TLH to SPA-TLH might be easier than the initial conversion from laparotomy to laparoscopy. The advantage of SPA-TLH over MPA-TLH is questionable, considering the longer learning curve; however SPA-TLH is an effective alternative for both the patient and surgeon.

Abstract
INTRODUCTION The dysregulation of maternal-fetal immune tolerance is one of the proposed mechanisms leading to preeclampsia. Galectins are key regulator proteins of the immune response in vertebrates and maternal-fetal immune tolerance in eutherian mammals. Previously we found that three genes in a Chr19 cluster encoding for human placental galectin-13 (PP13), galectin-14 and galectin-16 emerged during primate evolution and may confer immune tolerance to the semi-allogeneic fetus. MATERIALS AND METHODS This study involved various methodologies for gene and protein expression profiling, genomic DNA methylation analyses, functional assays on differentiating trophoblasts including gene silencing, luciferase reporter and methylation assays. These methods were applied on placental specimens, umbilical cord blood cells, primary trophoblasts and BeWo cells. Genomic DNA sequences were analyzed for transposable elements, transcription factor binding sites and evolutionary conservation. RESULTS AND DISCUSSION The villous trophoblastic expression of Chr19 cluster galectin genes is developmentally regulated by DNA methylation and induced by key transcription factors of villous placental development during trophoblast fusion and differentiation. This latter mechanism arose via the co-option of binding sites for these transcription factors through promoter evolution and the insertion of an anthropoid-specific L1PREC2 transposable element into the 5' untranslated region of an ancestral gene followed by gene duplication events. Among placental Chr19 cluster galectin genes, the expression of LGALS13 and LGALS14 is down-regulated in preterm severe preeclampsia associated with SGA. We reveal that this phenomenon is partly originated from the dysregulated expression of key transcription factors controlling trophoblastic functions and galectin gene expression. In addition, the differential DNA methylation of these genes was also observed in preterm preeclampsia irrespective of SGA. CONCLUSIONS These findings reveal the evolutionary origins of the placental expression of Chr19 cluster galectins. The complex dysregulation of these genes in preeclampsia may alter immune tolerance mechanisms at the maternal-fetal interface.

Abstract
The prevalence of anaemia is increasing globally. It has a close association with perioperative blood transfusion which, in turn, results in an increased risk of postoperative complications. Undesirable effects are not only limited to short-term, but also have long-term implications. Despite this, many patients undergo cardiac surgery with undiagnosed and untreated anaemia. We designed a retrospective, observational study to estimate the prevalence of anaemia in patients having cardiac surgery in Auckland District Health Board, blood transfusion rates and associated clinical outcome. Two hundred of seven hundred and twelve (28.1%) patients were anaemic. Red blood cell (RBC) transfusion rates were significantly higher in the anaemic group compared to the non-anaemic group (160 (80%) vs. 192 (38%), p-value <0.0001, RR (CI 95%) 2.133 (1.870-2.433)). Transfusion rates for fresh frozen plasma (FFP), cryoprecipitate and platelets were also higher in the anaemic group. Anaemia was significantly associated with the development of new infection (14 (7%) vs. 15 (2.9%), p-value 0.0193, RR (CI 95%) 2.389 (1.175-4.859)), prolonged ventilation time (47.01 hours vs. 23.59 hours, p-value 0.0076) and prolonged intensive care unit (ICU) stay (80.23 hours vs. 50.27, p-value 0.0011). Preoperative anaemia is highly prevalent and showed a clear link with significantly higher transfusion rates and postoperative morbidity. It is vital that a preoperative management plan for the correction of anaemia should be sought to improve patient safety and outcome.

Abstract
BACKGROUND The prevalence of community-associated meticillin-resistant Staphylococcus aureus (CA-MRSA) is increasing throughout the world and is an important cause of skin and soft tissue infection (SSTI) in children and neonates. AIM To describe the successful control of an outbreak caused by a new strain of CA-MRSA in a newborn nursery. METHODS The investigation of the outbreak in July 2012 is reported with the control measures taken. Molecular typing of the MRSA isolates was performed. FINDINGS An outbreak of SSTI caused by CA-MRSA occurred in a newborn nursery. Six neonates were infected in a one-month period [infection rate: 8.5% (6/71)]. A new variant of CA-MRSA was responsible, which was characterized as USA300-related, Panton-Valentine Leucocidin (PVL) positive, arginine catabolic mobile element (ACME) negative, sequence type 8 (ST8), staphylococcal cassette chromosome mec (SCCmec) type IVa, agr type I and spa type t008. The outbreak among term neonates followed a rapid transmission pattern and was successfully controlled by implementing various outbreak control measures, including universal chlorhexidine bathing. CONCLUSION This is the first report of a hospital outbreak caused by a USA300-related CA-MRSA clone in Korea. Early recognition and reinforcement of infection control measures are important in decreasing transmission of CA-MRSA in a hospital setting.

Abstract
The objective of this study was to evaluate the effects of soy sauce on the physicochemical and textural properties of tumbled chicken breasts. Chicken breasts marinated with distilled water (Con), 4% NaCl solution, 4% NaCl and lactic acid solution (pH 4.9), and soy sauce solution (4% salt concentration and pH 4.9) were vacuum tumbled at 3°C for 60 min. The chicken breast marinated with soy sauce solution showed lower lightness and higher redness and yellowness due to the color of the soy sauce. The acidic marinades led to a decrease in pH value of tumbled chicken breast. The acidic marinades increased collagen solubility of sample compared with 4% NaCl solution, resulting in decreased shear force. Water-holding capacity, marination and cooking yields, and solubility of myofibrillar proteins were mainly affected by the presence of salt in the marinade, rather than by pH alternation. Our results suggested that soy sauce marination can improve the tenderness of tumbled chicken breast.

Abstract
Spanish needles (Bidens bipinnata L.) is an annual herb that belongs to a genus of flowering plants in family Asteraceae native to United States, and tropical regions around world. The plant produces important flavonoid compounds quercitin and hyperoside that function as anti-allergens, anti-inflammatories, anti-microbials, and anti-cancer agents. Between July and October 2011 and 2012, white superficial mycelia were observed initially on leaf and stem portions, but later progressed to the flower head. Surveys showed that the disease was widespread in Gwangju and most areas of South Korea. Abundant, necrotic, dark brown spots showing chasmothecia were frequently observed in October and were abundant on the adaxial surface of leaves. Chasmothecia were blackish brown to yellow without typical appendages. They ranged from 51.2 to 71.1 (mean 66.8) μm in diameter. Conidia were formed singly and the primary conidia were ellipsoid, rounded at the apex, truncated base, and ranged from 25.4 to 33.2 (mean 27.3) μm long × 10.2 to 12.2 (mean 11.3) μm wide. Conidiophores were erect, 60.1 to 101.3 (mean 98.3) μm long × 6.2 to 9.2 (mean 7.3) μm wide. From extracted genomic DNA, the internal transcribed spacer (ITS) region inclusive of 5.8S and 28S rDNA was amplified with ITS1F (5'-TCCGTAGGTGAACCTGCGG-3') and LR5F (5'-GCTATCCTGAGGGAAAC-3'), and LROR (5'-ACCCGCTGAACTTAAGC-3') and LR5F primer sets, respectively. rDNA ITS (GenBank Accession No. JX512555) and 28S (JX512556) homologies of the fungus (EML-BBPW1) represented 99.6% (532/534) and 100% (661/661) identity values with Podosphaera xanthii (syn. P. fusca) AB040349 and P. xanthii (syn. P. fusca) AB462798, respectively. The rDNA sequence analysis revealed that the causal fungus matched P. xanthii (syn. P. fusca), forming a xanthii/fusca group (3,4). A pathogenicity test was performed on three plants in a greenhouse. The treated leaves were sealed in vinyl pack in humid condition for 2 days. Seven days after inoculation, similar symptoms were observed on the inoculated Spanish needles plant leaves. No symptoms were observed on control plants treated with distilled water. Koch's postulates were fulfilled by re-observing the fungal pathogen on the inoculated leaves. Podosphaera (syn. Sphaerotheca) xanthii (or fusca) has been known as an ubiquitous species with a broad host range. So far, five records regarding P. xanthii (=P. fusca) have been found in plants of genus Bidens. P. xanthii has been reported to occur on B. cernua in Belarus and Switzerland. In addition, the powdery mildew species was reported to occur on B. frondosa and B. tripartita in Korea, Russia, and Switzerland (2). To our knowledge, this is the first report of powdery mildew caused by P. xanthii on Spanish needles (B. bipinnata) in Korea. References: (1) U. Braun et al. Schlechtendalia 10:91, 2003. (2) D. F.

Abstract
This study investigated whether killer-cell immunoglobulin-like receptor (KIR) genes and human leukocyte antigen (HLA)-C alleles, receptors and ligands of natural killer cells are associated with the development of human papillomavirus (HPV)-related cervical disease in Korean women. Blood samples from 132 women with HPV-related cervical disease and 159 women without HPV infection were collected for genotyping of KIR genes and HLA-C alleles. Although no relationship was found between KIR genes and HPV-related cervical disease, a significant relationship was found between HLA-C alleles as ligands of KIR and HPV-related cervical disease. Women with HPV-related cervical disease were found to be significantly more likely to carry HLA-C*0303, particularly those with HPV 16 or 18 infection, and less likely to carry HLA-C*01 compared to women without HPV infection. HLA-C*0303 was found to confer susceptibility to HPV-related cervical disease, whereas HLA-C*01 was found to confer a protective effect against HPV-related cervical disease.

Abstract
The effect of acid-treated carbon nanotube (CNT) addition on the wear and dynamic mechanical thermal properties of basalt/epoxy woven composites was investigated in this study. Basalt/CNT/epoxy composites were fabricated by impregnating woven basalt fibers into epoxy resin mixed with 1 wt% CNTs which were acid-treated. Wear and DMA (dynamic mechanical analyzer) tests were performed on basalt/epoxy composites and basalt/CNT/epoxy composites. The results showed that the addition of the acid-treated CNTs improved the wear properties of basalt/epoxy woven composites. Specifically, the friction coefficient of the basalt/epoxy composite was stabilized in the range of 0.5-0.6 while it fell in the range of 0.3-0.4 for basalt/CNT/epoxy composites. The wear volume loss of the basalt/CNT/epoxy composites was approximately 68% lower than that of the basalt/epoxy composites. The results also showed that the glass transition temperature of basalt/CNT/epoxy composites was higher than that of basalt/epoxy composites. The improvement of wear properties of basalt/epoxy composites by the addition of acid-treated CNTs was caused by the homogeneous load transfer between basalt fibers and epoxy matrix due to the reinforcement of CNTs.

Abstract
C4d deposition is considered to be evidence of antibody-mediated rejection. This study was conducted to compare C4d immunoreactivity between villitis of unknown etiology (VUE) and cytomegaloviral placentitis. C4d immunohistochemistry was performed in cases with VUE (n = 16) and cytomegaloviral placentitis (n = 5). Distinct, linear C4d immunoreactivity along the syncytiotrophoblast was found in all VUE cases. In cytomegaloviral placentitis, the intensity of C4d immunoreactivity along the syncytiotrophoblast was not prominent, but cytoplasmic C4d immunoreactivity of villous cytotrophoblasts was frequently observed. Further screening of the cases with placental infarcts (n = 5) demonstrated prominent C4d immunoreactivity in the chorionic villi adjacent to the infarct. We report the characteristic co-localization of VUE and C4d immunoreactivity. The overall findings in this study strongly suggest that the complement activation is a common mechanism of diverse placental injuries associated with rejection, infection, and ischemia.

Abstract
INTRODUCTION We found isolated or clustered trophoblasts in the chorionic connective tissue of the extraplacental membranes, and defined this novel histologic feature as the "trophoblast islands of the chorionic connective tissue" (TICCT). This study was conducted to determine the clinical significance of TICCT. METHODS Immunohistochemistry for cytokeratin-7 was performed on the chorioamniotic membranes (N = 2155) obtained from singleton pregnancies of 1199 uncomplicated term and 956 preterm deliveries. The study groups comprised 1236 African-American and 919 Hispanic women. Gestational age ranged from 24(+0) weeks to 41(+6) weeks. Multiple logistic regression analysis was performed to investigate the magnitude of association between patient characteristics and the presence of TICCT. RESULTS The likelihood of TICCT was significantly associated with advancing gestational age both in term (OR: 1.29, 95% CI: 1.16-1.45, p < 0.001) and preterm deliveries (OR: 1.19, 95% CI: 1.07-1.32, p = 0.001) . Hispanic women were less likely than African-American women to have TICCT across gestation in term (OR: 0.23, 95% CI: 0.18-0.31, p < 0.001) and preterm pregnancies (OR: 0.41, 95% CI: 0.29-0.58, p < 0.001). Women with a female fetus were significantly more likely to have TICCT than women with a male fetus, in both term (OR: 1.64, 95% CI: 1.28-2.11, p < 0.001) and preterm gestations (OR: 2.04, 95% CI: 1.46-2.85, p < 0.001). TICCT was 40% less frequent in the presence of chronic placental inflammation [term (OR: 0.60, 95% CI: 0.45-0.81, p = 0.001) and preterm gestations (OR: 0.58, 95% CI: 0.40-0.84, p = 0.003)] and in parous women at term (OR: 0.60, 95% CI: 0.44-0.81, p = 0.001). CONCLUSIONS Our findings suggest that the duration of pregnancy, fetal sex, and parity may influence the behavior of extravillous trophoblast and placental mesenchymal cells.

Abstract
The objectives of this study were to evaluate effects of rigor state, thawing temperature, and processing on the physicochemical properties of intact frozen duck breast muscle and homogenates prepared with the frozen-thawed muscles. Prerigor breast muscle was frozen at -25°C and thawed at 4 and 15°C, and the physicochemical properties of duck breast frozen prerigor compared with those in frozen postrigor and 4°C chilled postrigor muscles. The homogenates prepared with duck breast frozen prerigor showed similar physicochemical properties as the frozen-thawed postrigor muscle homogenate. The thawing temperature did not affect the physicochemical properties of homogenates prepared with duck breast muscle frozen prerigor. Also, no significant differences (P > 0.05) in the ultimate pH value and color parameters were observed among the frozen-thawed treatments despite the differences in rigor state and thawing temperature. However, a higher thawing temperature of the intact frozen prerigor muscle resulted in an increase in thawing loss and shear force due to excessive muscle shortening. In this study, the intact duck breast that has undergone thaw-rigor showed main problems associated with thaw-rigor, such as higher thawing loss and shear force, regardless of thawing temperature. However, the processing (grinding and salting) decreased the difference in physicochemical properties due to rigor state before freezing and thawing temperature. Therefore, the frozen-thawed duck breast muscle used to manufacture ground-type meat product may be frozen before rigor onset.

Abstract
Interleukin-22 (IL-22) is a cytokine with epithelial reparative and regenerative properties that is produced by Th22 cells and by other immune cell subsets. Therefore, we explored the hypothesis that disruption of the gut barrier during HIV infection involves dysregulation of these cells in the gastrointestinal mucosa. Sigmoid IL-22-producing T cell and Th22 cells were dramatically depleted during chronic HIV infection, epithelial integrity was compromised, and microbial translocation was increased. These alterations were reversed after long-term antiretroviral therapy. While all mucosal IL-22-producing T-cell subsets were also depleted very early during HIV infection, at these early stages IL-22 production by non-T-cell populations (including NKp44+ cells) was increased and gut epithelial integrity was maintained. Circulating Th22 cells expressed a higher level of the HIV co-receptor/binding molecules CCR5 and α4β7 than CD4+ T-cell subsets in HIV-uninfected participants, but this was not the case after HIV infection. Finally, recombinant IL-22 was protective against HIV and tumor necrosis factor-α-induced gut epithelial damage in a validated in vitro gut epithelial system. We conclude that reduced IL-22 production and Th22 depletion in the gut mucosa are important factors in HIV mucosal immunopathogenesis.

Abstract
The effects of quality grade (which reflects relative marbling) on the chemical, physical and sensory properties was investigated using Korean native cattle (Hanwoo) beef. Thirty-six Hanwoo cows were slaughtered and the carcasses were graded at 24h postmortem according to the Korean carcass grading system. The quality grade 1 (high quality), grade 2 and grade 3 (low quality) were based on the marbling score of longissimus dorsi (LD) muscles. The effects of quality grade on the meat quality parameters of beef LD muscle were assessed during aging. Loin-eye area, fat thickness and yield grade were all similar for the three quality groups. Mean lean color, fat color and maturity scores did not differ among quality grade groups (P>0.05). pH, Sarcomere length, WHC, collagen content, cooking loss, shear force and MFI were not affected by quality grade groups. Drip loss for grade 1 group was significantly lower than that for grade 3 groups (P<0.05). At initial tenderness evaluation of steaks, no differences among the three grades were observed; however, with additional days of storage, grade 1 steaks had higher tenderness score than grade 3 steaks (P<0.05). Increased postmortem aging time improved tenderness attributes regardless of quality groups. No significant differences were found among the quality grade groups for flavor (P>0.05). The grade 1 group had the highest juiciness score, and grade 3 groups had the lowest score (P<0.05), but postmortem aging did not influence flavor and juiciness. The quality grades were more strongly related to juiciness than tenderness or flavor.

Abstract
Quantitative hepatitis B surface antigen (HBsAg) and hepatitis B e antigen (HBeAg) assays are emerging as effective tools of on-treatment predictors of response to antiviral agents, in addition to monitoring serum HBV DNA levels. However, the dynamic relationship between quantitative HBsAg, as well as HBeAg and HBV DNA, and the predictability of subsequent clinical outcomes during entecavir (ETV) therapy remain unclear. Eighty-two patients with HBeAg-positive chronic hepatitis B (CHB) received ETV therapy for ≥3 years. Virologic response (VR) after 3 years of ETV therapy was achieved in 73 (89.0%) patients. Among baseline and on-treatment factors, on-treatment HBV DNA levels performed better with respect to the prediction of response than HBsAg and HBeAg levels. Especially, the performance of absolute values of HBV DNA with respect to response was superior to HBV DNA decline from the baseline. The best predictive value was an absolute HBV DNA level of 2.3 log(10) IU/mL at month 6 (areas under the curve [AUROC], 0.977; 95% CI, 0.940-1.000; P < 0.001). HBeAg seroconversion after 3 years of therapy was achieved in 26 (31.7%) patients. On-treatment HBeAg levels performed better with respect to the prediction of seroconversion than HBsAg and HBV DNA levels. The best cut-off value for the HBeAg level at month 12 for the prediction of seroconversion was 0.62 log(10) PEIU/mL. Although the HBsAg level at baseline is often used to predict the antiviral potency of entecavir, on-treatment HBV DNA and HBeAg levels are more helpful for prediction of subsequent clinical outcomes in HBeAg-positive CHB patients with entecavir treatment.

Abstract
BACKGROUND/PURPOSE Bidirectional trafficking of cells between the mother and the fetus is routine in pregnancy and a component of maternal-fetal tolerance. Changes in fetal-to-maternal cellular trafficking have been reported in prenatal complications, but maternal-to-fetal trafficking has never been studied in the context of fetal intervention. We hypothesized that patients undergoing open fetal surgery would have altered maternal-fetal cellular trafficking. METHODS Cellular trafficking was analyzed in patients with myelomeningocele (MMC) who underwent open fetal surgical repair (n = 5), patients with MMC who had routine postnatal repair (n = 6), and healthy control healthy patients (n = 9). As an additional control for the fetal operation, trafficking was also analyzed in patients who were delivered by an ex utero intrapartum treatment procedure (n = 6). Microchimerism in maternal and cord blood was determined using quantitative real-time polymerase chain reaction for nonshared alleles. RESULTS Maternal-to-fetal trafficking was significantly increased in patients who underwent open fetal surgery for MMC compared with healthy controls, patients who underwent postnatal MMC repair, and patients who underwent ex utero intrapartum treatment. There were no differences in fetal-to-maternal cell trafficking among groups. CONCLUSION Patients undergoing open fetal surgery for MMC have elevated levels of maternal microchimerism. These results suggest altered trafficking and/or increased proliferation of maternal cells in fetal blood and may have important implications for preterm labor.

Abstract
OBJECTIVE To identify characteristics of the cell-mediated immune (CMI) response to human papillomavirus-16 (HPV) E7 viral peptide pools to help the formulation of therapeutic vaccines. DESIGN Prospective study. Population. Korean women. SETTING University hospital. METHODS From December 2008 to August 2010, 33 HPV-16-positive patients, seven patients exhibiting a high-risk HPV infection other than HPV-16 with grade 2/3 cervical intraepithelial neoplasm (CIN2/3), and nine healthy control donors were enrolled. MAIN OUTCOME MEASURES CMI response to synthetic HPV-16 E7 overlapping peptide pools using the IFN-γ ELISPOT assay. RESULTS The E7 sequence comprising amino acids 16-55 was a major immunogenic region. The CMI response to HPV-16 E7 is highly type-specific. The follow-up CMI response may last longer than expected after the lesion is resected. CONCLUSIONS We found that the E7 sequence comprising amino acids 16-55 is a major immunogenic region that is critical for the T-cell-mediated immune response with CIN2/3 or cervical cancer. The identification of CMI responses to HPV-16 E7 peptide pools may provide insight into therapeutic vaccine trials for the control of HPV-associated diseases.
