Abstract
Little is known about biopsychosocial factors relating to pre-exposure prophylaxis (PrEP) awareness among people with either heterosexual or injection drug use HIV risk behaviors. Participants engaged in vaginal/anal sex with a person of the opposite sex (N = 515) or were people who injected drugs (PWID; N = 451) in the past 12 months from 2018-2019 in Boston, MA. We examined associations between PrEP awareness and: homelessness; perceived HIV-related stigma; country of birth; bacterial STDs, chlamydia, and/or gonorrhea in the past 12 months, lifetime hepatitis C virus (HCV) infection, sexual orientation, and poverty. More PWID (36.8%) were aware of PrEP than people with heterosexual HIV risk (28%; p = .001). Among people with heterosexual risk, homelessness (aOR = 1.99, p = .003), and among PWID: homelessness (aOR = 2.11, p = .032); bacterial STD (aOR = 2.96, p = .012); chlamydia (aOR = 6.14, p = .008); and HCV (aOR = 2.40, p < .001) were associated with increased likelihood of PrEP awareness. In the combined sample: homelessness (aOR = 2.25, p < .001); HCV (aOR = 2.18, p < .001); identifying as homosexual (aOR = 3.71, p = .036); and bisexual (aOR = 1.55, p = .016) were each associated with PrEP awareness. Although having an STD, HCV, identifying as homosexual or bisexual, and experiencing homelessness were associated with increased PrEP awareness, most participants were unaware of PrEP. Efforts to increase PrEP awareness could engage PWID and heterosexual HIV risk behavior.

Abstract
BACKGROUND AND PURPOSE To evaluate modern clinical outcomes for patients with brain-only metastatic non-small cell lung cancer (NSCLC) treated with intracranial stereotactic radiosurgery (SRS) with or without definitive treatment of the primary site. MATERIALS AND METHODS Patients with synchronously diagnosed NSCLC and brain-only metastatic disease treated with intracranial SRS at a single institution were retrospectively identified. Patients were stratified based on whether they did (A) or did not (B) receive definitive primary site treatment. Patient characteristics and clinical outcomes were compared. RESULTS From 2008 to 2022, 103 patients were identified, 53 of whom received definitive primary site treatment. Median follow-up was 2.1 y (A) and 0.8 y (B) (p < 0.001). 28 (53 %) patients in Group A received immune checkpoint inhibitor (ICI) therapy versus 19 (38 %) in Group B (p = 0.13) and there were no other statistically significant baseline or treatment characteristic differences between the groups. 5-year local-PFS was 34.5 % (A) versus 0 % (B) (p < 0.001). 5-year regional-PFS was 33.0 % (A) versus 0 % (B) (p < 0.001). 5-year distant body-PFS was 34.0 % (A) versus 0 % (B) (p < 0.001). 5-year CNS-PFS was 14.7 % (A) versus 0 % (B) (p = 0.12). 5-year OS was 40.2 % (A) versus 0 % (B) (p = 0.001). 5-year CSS was 67.6 % (A) versus 0 % (B) (p = 0.002). On multivariable analysis, lack of definitive treatment to the primary site (HR = 2.40), AJCC T3-4 disease (HR = 2.73), and lack of ICI therapy (HR = 2.86) were significant predictors of death. CONCLUSION Definitive treatment to the thoracic primary site in patients with brain-only metastatic NSCLC after intracranial radiosurgery was associated with slower progression of disease and improved survival.

Abstract
INTRODUCTION To investigate the significance of perioperative hepatitis B virus (HBV) DNA changes for predicting recurrence in patients with HBV-related hepatocellular carcinoma (HCC) undergoing liver resection (LR). METHODS From 2013 to 2020, 241 patients with HBV-related HCC who underwent LR in five Hallym university-affiliated hospitals were enrolled. The serum HBV DNA level, together with other clinicopathological variables, was analyzed for association with HCC recurrence. RESULTS Preoperatively, 99 patients had undetectable HBV DNA and 142 had detectable viral levels. Of those with detectable viral levels, 72 rapidly progressed to undetectable levels within 3 mo after LR (Rapid group), and 70 showed persistently detectable levels (Nonrapid group). The Rapid group had a better recurrence-free survival (RFS) rate than the Nonrapid group (1-y, 3-y RFS = 75.4%, 57.3%, versus 54.7%, 39.9%, respectively, P = 0.012). In the subgroup analysis, the Rapid group had a better RFS rate in early stages (1-y, 3-y RFS = 82.6%, 68.5%, versus 62.8%, 45.8%, respectively, P = 0.005); however, the RFS rates between the two groups were comparable in the advanced stage (1-y, 3-y RFS = 61.1%, 16.7% versus 45.5%, 22.7%, respectively, P = 0.994). Among the 142 patients with preoperatively detectable HBV DNA, persistently detectable HBV DNA within 3 mo postoperatively (hazard ratio [HR] = 1.7, P = 0.022), large tumor size (HR = 2.7, P < 0.001), multiple tumors (HR = 3.2, P < 0.001), and microvascular invasion (HR = 1.7, P = 0.028) were independent risk factors for RFS in multivariate analysis. CONCLUSIONS Rapidly undetectable HBV DNA after LR is associated with a better prognosis for recurrence in patients with HCC. Therefore, appropriate treatment and/or screening may be necessary for patients who do not return to undetectable HBV DNA after LR.

Abstract
Toxic epidermal necrolysis (TEN) involves extensive mucocutaneous loss, and care is supportive. The approach to wound care includes surgical debridement or using dressings while leaving the epidermis intact. Robust evidence for either approach is lacking. We compared surgical debridement to the use of dressings while leaving the epidermis in situ (referred to hereon as dressings) in adult patients with TEN. The primary outcome assessed was mortality. The secondary outcome was time to re-epithelialisation. The impact of medications was evaluated. An individual patient data (IPD) systematic review and meta-analysis was undertaken. A random effects meta-analysis and survival analysis for IPD data examined mortality, re-epithelisation time and the effect of systemic medications. The quality of evidence was rated per the Grading of Recommendations Assessment, Development and Evaluation (GRADE). PROSPERO: CRD42021266611 Fifty-four studies involving 227 patients were included in the systematic review and meta-analysis, with a GRADE from very low to moderate. There was no difference in survival in patients who had surgical debridement or dressings (univariate: p = 0.91, multivariate: p = 0.31). Patients who received dressings re-epithelialised faster than patients who underwent debridement (multivariate HR: 1.96 [1.09-3.51], p = 0.023). Intravenous immunoglobulin (univariate HR: 0.21 [0.09-0.45], p < 0.001; multivariate HR: 0.22 [0.09-0.53], p < 0.001) and cyclosporin significantly reduced mortality (univariate HR: 0.09 [0.01-0.96], p = 0.046; multivariate HR: 0.06 [0.01-0.73], p = 0.028) irrespective of the wound care. This study supports the expert consensus of the dermatology hospitalists, that wound care in patients with TEN should be supportive with the epidermis left intact and supported with dressings, which leads to faster re-epithelialisation.

Abstract
PURPOSE/OBJECTIVE(S) The aim of this study is to evaluate the safety and effectiveness of proton re-irradiation with concurrent hyperthermia in the treatment of recurrent breast cancer. MATERIALS/METHODS We retrospectively identified patients previously treated with photon whole breast or chest wall irradiation for a primary breast cancer at our institution, who subsequently developed a histologically-confirmed locoregional recurrence or new ipsilateral primary breast cancer and underwent proton chest wall re-irradiation with concurrent hyperthermia as part of definitive treatment. Acute toxicity was evaluated once weekly while on-treatment and at 2 weeks and 3 months post-treatment. Toxicities were graded according to CTCAE v4.0. RESULTS Fifteen patients received proton re-irradiation with concurrent superficial hyperthermia at our institution from August 2018 to December 2022. Median interval between radiation treatment courses was 7.7 years (range 1-30 years). Four patients (26%) had gross, unresected disease at the time of re-treatment. The median initial radiation dose, re-irradiation dose, and cumulative EQD2 was 60.4 Gy (50.6-61.2 Gy), 60 Gy (RBE) (45-66 Gy (RBE)), and 120 Gy (RBE) (103-126 Gy (RBE)), respectively. Patients received a median of 9 (3-14) concurrent hyperthermia treatments delivered twice weekly, and 13 patients (87%) received seven or more hyperthermia treatments. Median toxicity follow-up was 9 months (0-36 months). Acute grade 3 toxicities included two patients (13%) with grade 3 dermatitis, both of which resolved with conservative management within 3 months of treatment completion. Chronic grade 2 or higher toxicities included two grade 2 hyperpigmentation, one grade 3 induration, one grade 2 telangiectasia, and one grade 2 rib fracture. There were no grade 4-5 acute or late toxicities. There was one in-field local recurrence and one regional recurrence outside of the re-irradiation field. Both patients had gross, unresected disease at the time of re-irradiation. Two patients (13%) developed distant disease. CONCLUSION Proton re-irradiation with concurrent hyperthermia is feasible and well-tolerated in the re-treatment of breast cancer. Further studies are warranted to determine long-term toxicity and oncologic outcomes.

Abstract
We have developed a flexible undergraduate curriculum that leverages the place-based research of environmental microbiomes to increase the number of Indigenous researchers in microbiology, data science and scientific computing. Monitoring Environmental Microbiomes (MEM) provides a curriculum and research framework designed to integrate an Indigenous approach when conducting authentic scientific research and to build interest and confidence at the undergraduate level. MEM has been successfully implemented as a short summer workshop to introduce computing practices in microbiome analysis. Based on self-assessed student knowledge of topics and skills, increased scientific confidence and interest in genomics careers were observed. We propose MEM be incorporated in a scalable course-based research experience for undergraduate institutions, including tribal colleges and universities, community colleges and other minority serving institutions. This coupled curricular and research framework explicitly considers cultural perspectives, access and equity to train a diverse future workforce that is more informed to engage in microbiome research and to translate microbiome science to benefit community and environmental health.

Abstract
Microbiologically influenced corrosion (MIC) is a phenomenon of increasing concern that affects various materials and sectors of society. MIC describes the effects, often negative, that a material can experience due to the presence of microorganisms. Unfortunately, although several research groups and industrial actors worldwide have already addressed MIC, discussions are fragmented, while information sharing and willingness to reach out to other disciplines are limited. A truly interdisciplinary approach, which would be logical for this material/biology/chemistry-related challenge, is rarely taken. In this review, we highlight critical non-biological aspects of MIC that can sometimes be overlooked by microbiologists working on MIC but are highly relevant for an overall understanding of this phenomenon. Here, we identify gaps, methods, and approaches to help solve MIC-related challenges, with an emphasis on the MIC of metals. We also discuss the application of existing tools and approaches for managing MIC and propose ideas to promote an improved understanding of MIC. Furthermore, we highlight areas where the insights and expertise of microbiologists are needed to help progress this field.

Abstract
BACKGROUND The transosseous anchorless repair (ToR) technique was recently introduced to avoid suture anchor-related problems. While favorable outcomes of the ToR technique have been reported, no previous studies on peri-implant cyst formation with the ToR technique exist. Therefore, this study compared the clinical outcomes and prevalence of peri-implant cyst formation between the ToR technique and the conventional transosseous equivalent technique using suture anchors (SA). METHODS Cases with arthroscopic rotator cuff repair (ARCR) between 2016 and 2018 treated with the double-row suture bridge technique were retrospectively reviewed. Patients were divided into ToR and SA groups. To compare clinical outcomes, 19 ToR and 57 SA cases without intraoperative implant failure were selected using propensity score matching (PSM). While intraoperative implant failure rate was analyzed before PSM, retear rate, peri-implant cyst formation rate, and functional outcomes were compared after PSM. RESULTS The intraoperative implant failure rate (ToR, 8% vs. SA, 15.3%) and retear rate (ToR, 5.3% vs. SA, 19.3%) did not differ between the two groups (all P>0.05). However, peri-implant cysts were not observed in the ToR group, while they were observed in 16.7% of the SA group (P=0.008). Postoperative functional outcomes were not significantly different between the two groups (all P>0.05). CONCLUSIONS The ToR technique produced comparable clinical outcomes to conventional techniques. Considering the prospect of potential additional surgeries, the absence of peri-implant cyst formation might be an advantage of ToR. Furthermore, ToR might reduce the medical costs related to suture anchors and, thereby, could be a useful option for ARCR. Level of evidence: III.

Abstract
Gout is the most common form of arthritis, with the prevalence increasing worldwide. The present treatment guidelines provide recommendations for the appropriate treatment of acute gout, management during the inter-critical period, and prevention of chronic complications. The guidelines were developed based on evidence-based medicine and draft recommendations finalized after expert consensus. These guidelines are designed to provide clinicians with clinical evidence to enable efficient treatment of gout.

Abstract
Liver transplantation (LT) in patients with hepatocellular carcinoma (HCC) with bile duct tumor thrombus (BDTT) remains controversial. This study analyzed the recurrence and overall survival rates through long-term results after LT in HCC patients with BDTT and compared the results after LT in HCC patients with portal vein tumor thrombus (PVTT). We performed a retrospective study of 45 patients with PVTT, 16 patients with BDTT, and 11 patients with coexisting PVTT and BDTT among HCC patients who underwent LT at a single center from 1999 to 2020. The HCC recurrence rates were 40.4% at 1 year, 30.3.3% at 2 years, and 27.6% at 3 years in the PVTT group; 66.7%, 53.3%, and 46.7% in the BDTT group; and 22.2%, 22.2%, and 0% in the coexisting group (p = 0.183). Overall patient survival rates were 68.4% at 1 year, 54.3% at 2 years, and 41.7% at 3 years in the PVTT group; 81.3%, 62.5%, and 48.2% in the BDTT group; and 63.6%, 27.3%, and 0% in the coexisting group (p = 0.157). In the multivariate analysis, the pre-transplantation model for tumor recurrence after liver transplantation (MoRAL) score and model for end-stage liver disease (MELD) score were found to be independent risk factors for recurrence and survival in all groups. HCC patients with BDTT showed no difference in recurrence and survival compared with HCC patients with PVTT at the long-term follow-up after LT.

Abstract
BACKGROUND Healthcare workers (HCWs) with latent tuberculosis infection (LTBI) have a high risk of active tuberculosis and need systematic LTBI screening and treatment. However, acceptance and adherence rates of LTBI treatment are low. AIMS To examine the specific reasons for the loss at each LTBI treatment-cascade stage: acceptance, continuation and completion of LTBI treatment in HCWs. METHODS This retrospective descriptive study was conducted among 61 HCWs with an interferon-gamma release assay-confirmed LTBI diagnosis who were prescribed LTBI treatment at a tertiary hospital in the Republic of Korea. Data were analysed using Pearson's chi-square, Fisher's exact, independent t-test and Mann-Whitney U-test. A word cloud analysis was used to describe the perceived meaning of LTBI in HCWs. RESULTS HCWs who refused or discontinued LTBI treatment perceived LTBI as 'not a big deal', whereas HCWs who completed LTBI treatment had a high-risk perception of the LTBI prognosis, such as 'frightened about adverse prognosis'. Determinants of non-adherence to the recommended LTBI treatment included a busy work schedule, side effects of anti-tuberculosis agents and the inconvenience of regularly taking anti-tuberculosis agents. CONCLUSIONS To ensure LTBI treatment adherence in HCWs, effective interventions that are customized to each stage of the LTBI treatment should be developed, with due consideration of the stage-specific perceived facilitators and barriers in the LTBI treatment cascade.

Abstract
BACKGROUND Schizophrenia is a chronic, debilitating disorder characterised by distorted thinking, perceptions, behaviours, and even language impairments. We investigated the linguistic anomalies in Korean schizophrenia patients compared to non-psychotic psychiatric controls to determine whether the linguistic anomalies in English speakers with schizophrenia were replicated in Korean speakers. METHODS Thirty-four schizophrenia patients and 70 non-psychotic psychiatric controls were included in this study. The SCT was utilised as the text data for analysis. For linguistic analysis, we evaluated texts regarding semantics and syntax. We separately counted the number of semantic or syntactic errors in the written texts of study participants and compared them between patients and controls. RESULTS Schizophrenia patients showed significantly more semantic errors (p < .001) and syntactic errors (p < .001) per 1,000 characters than non-psychotic psychiatric controls. Specifically, inappropriate word or syntactic component selection is noticeable in schizophrenia patients. These differences were still significant after adjusting for general intelligence measured by the K-WAIS-IV. CONCLUSION Schizophrenia patients showed both semantic and syntactic errors in written language. Moreover, these errors seemed to be partly independent of general intelligence. Notably, patients showed a noticeable number of syntactic errors. Further investigation into the language of patients with schizophrenia and schizophrenia-spectrum disorders is required.

Abstract
AIMS To evaluate the clinical efficacy of adding temozolomide (TMZ) to preoperative capecitabine (CAP)-based chemoradiotherapy in patients with locally advanced rectal cancer (LARC) and validate O6-methylguanine DNA methyltransferase (MGMT) methylation status as a predictive marker for TMZ combined regimens. MATERIALS AND METHODS LARC patients with clinical stage II (cT3-4N0) or III (cTanyN+) disease were enrolled. They were stratified into unmethylated MGMT (uMGMT) and methylated MGMT (mMGMT) groups by methylation-specific polymerase chain reaction before randomisation and were then randomly assigned (1:1) to one of four treatment arms: uMGMT/CAP (arm A), uMGMT/TMZ + CAP (arm B), mMGMT/CAP (arm C) and mMGMT/TMZ + CAP (arm D). The primary end point was the pathological complete response (pCR) rate. RESULTS Between November 2017 and July 2020, 64 patients were randomised. Slow accrual caused early study termination. After excluding four ineligible patients, 60 were included in the full analysis set. The pCR rate was 15.0% (9/60), 0%, 14.3%, 18.8% and 26.7% for the entire cohort, arms A, B, C and D, respectively (P = 0.0498 between arms A and D). The pCR rate was 9.7% in the CAP group (arms A + C), 20.7% in the TMZ + CAP group (arms B + D), 6.9% in the uMGMT group (arms A + B) and 22.6% in the mMGMT group (arms C + D). Grade 1-2 nausea or vomiting was significantly more frequent in the TMZ + CAP treatment groups (arms B + D) than in the CAP treatment groups (arms A + C, P < 0.001) with no difference in grade 3 adverse events. There were no grade 4 or 5 adverse events. CONCLUSION The addition of TMZ to CAP-based chemoradiotherapy tended to improve pCR rates, particularly in those with mMGMT LARC. MGMT status may warrant further investigation as a predictive biomarker for chemotherapeutic agents and radiotherapy.

Abstract
Abstract
Background
Aldosterone is an important mediator of hypertension, particularly resistant hypertension, heart failure, and chronic kidney disease. PB6440 is a potent inhibitor of aldosterone synthase (CYP11B2) with high selectivity over the closely related enzyme CYP11B1. In previous studies in cynomolgus monkeys, PB6440 exhibited excellent oral bioavailability and a marked suppression of aldosterone synthesis at doses as low as 1 mg/kg/day. Importantly, no effect was observed on cortisol production nor significant changes noted in plasma concentrations of the steroid precursors 11-deoxycortisol or deoxycorticosterone (DOC), which are dependent on CYP11B1 activity. The purpose of the current study was to assess the safety and pharmacodynamics of higher doses of PB6440 in the cynomolgus monkey in order to determine a therapeutic index prior to initiation of studies in humans.
Methods
Male and female cynomolgus monkeys (2/sex/dose group) were administered 0, 10, 30 or 100 mg/kg PB6440 once-daily for 14 days by oral gavage. Assessment of safety was based on mortality, clinical observations, body weights, and clinical and anatomic pathology. Blood samples were also collected for pharmacodynamic analysis, including aldosterone, cortisol, 11-deoxycortisol, DOC, and ACTH.
Results
PB6440 was well tolerated at all doses. There were no deaths and no reports of clinical observations at any dose level. Mild decreases in body weight were observed in PB6440-treated animals, which were likely due to the diuretic effects of the compound. PB6440 caused an increase in adrenal weights which was associated with hypertrophy of the adrenal zona fasciculata, a finding which has previously been observed with other aldosterone synthase inhibitors. PB6440 led to marked declines in basal aldosterone levels of −97%, −97% and −98% from baseline at 10, 30 and 100 mg/kg/day, respectively, at 24-hours following the final dose. Despite these clear declines in circulating aldosterone levels, no meaningful changes in cortisol, 11-deoxycortisol, DOC, or ACTH levels were observed, supporting lack of CYP11B1 inhibition. PB6440 led to expected decreases in plasma sodium (up to 7 nmol/L at the high dose). No effect on plasma potassium levels were observed at any dose level.
Conclusions
PB6440 was well tolerated in the cynomolgus monkey at doses that are much higher than needed for potent aldosterone suppression based on previous studies. At the highest dose level tested (100 mg/kg), which led to a 98% reduction in basal aldosterone levels, no evidence of significant CYP11B1 inhibition was observed. The absence of an increase in plasma potassium in the presence of a plasma sodium decline merits further study. Thus, PB6440 is a highly selective novel aldosterone synthase inhibitor for the potential treatment of hypertension, heart failure, and chronic kidney disease in humans.

Abstract
BACKGROUND: Rapid diagnosis of drug-resistant TB is critical for early initiation of effective therapy. YD Diagnostics in South Korea recently developed the MolecuTech® REBA MTB-XMDR test to rapidly detect multidrug-resistant TB (MDR-TB), pre-extensively drug-resistant TB (pre-XDR-TB) and resistance to second-line injectable drugs (SLIDs) simultaneously using a fully automated test platform. This study aimed to evaluate the MolecuTech® test for the detection of MDR- and pre-XDR-TB, as well as SLID resistance.METHODS: A total of 151 clinical Mycobacterium tuberculosis isolates from South Korea were tested using the MolecuTech test, and the results were analysed by comparing these with phenotypic drug susceptibility testing (pDST) and sequencing.RESULTS: Compared to pDST, the MolecuTech test showed a sensitivity and specificity of respectively 97.7% and 100.0% for rifampicin (RIF), 82.4% and 100.0% for isoniazid (INH), 97.5% and 97.2% for fluoroquinolones (FQs), and 94.0% and 98.8% for SLIDs. Concordances with the sequencing results of each resistance determinant were 99.3% for RIF, 96.7% for INH, 98.7% for FQs and 99.3% for SLIDs.CONCLUSION: The MolecuTech test is an efficient and reliable rapid molecular diagnostic tool for the simultaneous screening of MDR- and pre-XDR-TB.

Abstract
AIM To evaluate the radiological features of isolated posterior inferior cerebellar artery dissection (PICAD) and the feasibility of using high-resolution vessel-wall imaging (HR-VWI) for diagnosing PICAD. MATERIALS AND METHODS Three hundred and nine patients with arterial dissection involving the posterior cerebral circulation, who underwent HR-VWI between March 2012 and July 2019 were reviewed retrospectively. Among them, 44 patients (14.2%) were diagnosed with isolated PICAD in consensus among a neuroradiologist, a neurointerventionist, and a neurologist. Two neuroradiologists reviewed the vessel wall images independently for evidence of dissection (dissection flap, outer diameter enlargement on T2-weighted imaging [WI], mural haematoma). Diagnostic confidence was also scored on a five-point scale. Intra- and interobserver agreement for diagnosing PICAD and detecting evidence of dissection were evaluated. RESULTS Dissection flaps were seen on T2WI in all cases (100%) and on contrast-enhanced T1WI in 34 patients (79.1%). Outer diameter enlargement of the steno-occlusive lesions on angiography was detected in most cases (97.7%). A mural haematoma was detected on three-dimensional (3D) contrast-enhanced motion-sensitised driven-equilibrium T1WI in 97.1% of the cases. The mean diagnostic confidence score derived by two neuroradiologists was 4.72. The two reviewers showed substantial to almost perfect agreement (weighted kappa coefficient: 0.62-0.97). CONCLUSION Use of HR-VWI as a diagnostic tool for PICAD is feasible, and a dissection flap with outer wall enlargement on HR-T2WI allows confident dissection diagnosis. The present data suggest that PICAD might be considered as a stroke aetiology in patients with unexplained ischaemic stroke in the PICA territory, and that PICA evaluation with HR-VWI is both necessary and feasible.

Abstract
OBJECTIVE The impact of the coronavirus disease 2019 (COVID-19) pandemic on weight gain in children and adolescents remains unknown. We aimed to identify an estimated 15-year trend in mean body mass index (BMI) changes and prevalence of obesity and overweight among Korean adolescents from 2005 to 2020, including the period of the COVID-19 pandemic. PATIENTS AND METHODS We analyzed data taken from a nationwide survey (Korea Youth Risk Behavior Survey), between 2005 and 2020. Representative samples of one million Korean adolescents aged 13-18 years (n=1,057,885) were examined. The 15-year trends in mean BMI and proportion of obesity or overweight, and the changes due to the COVID-19 pandemic were analyzed. RESULTS The data of 1,057,885 Korean adolescents were analyzed (mean age: 14.98 years; females, 48.4%). The estimated weighted mean BMI was 20.5 kg/m2 [95% confidence interval (CI), 20.4-20.5] from 2005 to 2008 and 21.5 kg/m2 (95% CI, 21.4-21.6) in 2020 (during the COVID-19 pandemic). Although the 15-year trend of mean BMI gradually increased, the change in mean BMI before and during the pandemic significantly lessened (βdiff, -0.027; 95% CI, -0.028 to -0.026). The 15-year (2005-2020) trend changes in the prevalence of obesity and overweight were similar (obesity prevalence from 2005-2008, 3.2%; 95% CI, 3.1-3.3 vs. obesity prevalence in 2020, 8.6%; 95% CI, 8.2-9.0; βdiff, -0.309; 95% CI, -0.330 to -0.288). CONCLUSIONS The 15-year trend of overall mean BMI and obesity and overweight prevalence demonstrated a significant increase; however, its slope decreased during the pandemic. These landmark results suggest the need for the development of precise strategies to prevent pediatric obesity and overweight during the COVID-19 pandemic.

Abstract
The mass of the W boson, a mediator of the weak force between elementary particles, is tightly constrained by the symmetries of the standard model of particle physics. The Higgs boson was the last missing component of the model. After observation of the Higgs boson, a measurement of the W boson mass provides a stringent test of the model. We measure the W boson mass, MW, using data corresponding to 8.8 inverse femtobarns of integrated luminosity collected in proton-antiproton collisions at a 1.96 tera-electron volt center-of-mass energy with the CDF II detector at the Fermilab Tevatron collider. A sample of approximately 4 million W boson candidates is used to obtain [Formula: see text], the precision of which exceeds that of all previous measurements combined (stat, statistical uncertainty; syst, systematic uncertainty; MeV, mega-electron volts; c, speed of light in a vacuum). This measurement is in significant tension with the standard model expectation.

Abstract
OBJECTIVE Although cartilage degeneration and invasion of the subchondral bone plate in entheseal lesion has been considered to consequently lead bony ankylosis in ankylosing spondylitis (AS), no evident mechanisms are known. DESIGN To identify histopathological and physiological changes in enthesitis-related ankylosis in AS, we performed molecular characterization of transcription factors and surface markers, and transcriptome analysis with human tissues. Entheseal tissue containing subchondral bone was obtained from the facet joints of 9 patients with AS and 10 disease controls, and assessed by using differential staining techniques. Enthesis cells were isolated, characterized, stimulated with TNF and/or IL-17A, and analysed by cell-based experimental tools. RESULTS We found diffusely distributed granular tissue and cartilage in the subchondral bone in AS. Co-expression of SOX9, a specific transcription factor in cartilage, and matrix metalloproteinase 13 (MMP13) was found in the granular tissues within the subchondral bone from AS patients. Intriguingly, SOX9 expression was significantly higher in AS enthesis cells than controls and correlated with TNFR1 and IL-17RA expressions, which is important for high reactivity to TNF and IL-17A cytokines. Co-stimulation by TNF and IL-17A resulted in accelerated mineralization/calcification features, and increased OCN expression in AS enthesis cells. Furthermore, SOX9 overexpression in enthesis leads to promoting mineralization feature by TNF and IL-17A stimuli. Finally, OCN expression is elevated in the destructive enthesis of advanced AS. CONCLUSION These findings provide insight into the links between inflammation and the mineralization of entheseal tissue as the initiation of spinal ankylosis, emphasizing the importance of SOX9+ enthesis cells.

Abstract
Deficient angiogenesis and disturbed osteogenesis are key factors for the development of nonunions. Mineral-coated microparticles (MCM) represent a sophisticated carrier system for the delivery of vascular endothelial growth factor (VEGF) and bone morphogenetic protein (BMP)-2. In this study, we investigated whether a combination of VEGF- and BMP-2-loaded MCM (MCM + VB) with a ratio of 1:2 improves bone repair in non-unions. For this purpose, we applied MCM + VB or unloaded MCM in a murine non-union model and studied the process of bone healing by means of radiological, biomechanical, histomorphometric, immunohistochemical and Western blot techniques after 14 and 70 days. MCM-free non-unions served as controls. Bone defects treated with MCM + VB exhibited osseous bridging, an improved biomechanical stiffness, an increased bone volume within the callus including ongoing mineralization, increased vascularization, and a histologically larger total periosteal callus area consisting predominantly of osseous tissue when compared to defects of the other groups. Western blot analyses on day 14 revealed a higher expression of osteoprotegerin (OPG) and vice versa reduced expression of receptor activator of NF-κB ligand (RANKL) in bone defects treated with MCM + VB. On day 70, these defects exhibited an increased expression of erythropoietin (EPO), EPO-receptor and BMP-4. These findings indicate that the use of MCM for spatiotemporal controlled delivery of VEGF and BMP-2 shows great potential to improve bone healing in atrophic non-unions by promoting angiogenesis and osteogenesis as well as reducing early osteoclast activity.

Abstract
OBJECTIVE We aimed to evaluate the reliability and validity of the adapted Korean version of the Quality-of-Life Profile for Spine Deformities (QLPSD) questionnaire. PATIENTS AND METHODS English version of QLPSD was translated into Korean according to previously published guidelines. The Korean version of the QLPSD questionnaire and the Korean version of the SRS-22 was sent to 120 consecutive idiopathic scoliosis patients wearing braces recruited from the outpatient clinic. Reliability assessment and construct validity were evaluated. RESULTS The intraobserver reliability of all items in the questionnaire had a kappa statistic of agreement greater than 0.6. The QLPSD showed good test/re-test reliability (ICC = 0.815). The internal consistency of Cronbach's α was found to be very good (α = 0.918). The Korean version of QLPSD showed a significant correlation with the SRS-22 total score (p<0.001, r=-0.811) and single SRS-22 domains scores. CONCLUSIONS The adapted Korean version of the QLPSD was successfully translated and showed good measurement properties. As such, it is considered suitable for outcome assessments in Korean-speaking patients with idiopathic scoliosis.

Abstract
Consider a multiplex network formed by two layers indicating social interactions: the first layer is a friendship network and the second layer is a network of business relations. In this duplex network each pair of individuals can be connected in different ways: they can be connected by a friendship but not connected by a business relation, they can be connected by a business relation without being friends, or they can be simultaneously friends and in a business relation. In the latter case we say that the links in different layers overlap. These three types of connections are called multilinks and the multidegree indicates the sum of multilinks of a given type that are incident to a given node. Previous opinion models on multilayer networks have mostly neglected the effect of link overlap. Here we show that link overlap can have important effects in the formation of a majority opinion. Indeed, the formation of a majority opinion can be significantly influenced by the statistical properties of multilinks, and in particular by the multidegree distribution. To quantitatively address this problem, we study a simple spin model, called the Ashkin-Teller model, including two-body and four-body interactions between nodes in different layers. Here we fully investigate the rich phase diagram of this model which includes a large variety of phase transitions. Indeed, the phase diagram or the model displays continuous, discontinuous, and hybrid phase transitions, and successive jumps of the order parameters within the Baxter phase.

Abstract
Abstract
Introduction/Objective
Cystic angiomatosis is a very rare entity characterized by multifocal cystic angiomatous lesions of the skeletal system, occasionally involving visceral organ systems. Clinical presentation and progression are extremely variable. Cases with liver involvement are even rarer, and have been described as invariably fatal. The pathogenesis of this disorder is poorly understood, and no treatments are currently available.
Methods/Case Report
A 24 year old man with history of polysubstance abuse and untreated hepatitis C presented with acute abdominal pain. Imaging revealed hepatosplenomegaly and multiple liver, spleen, and skeletal lesions. Differential diagnoses included metastatic disease, lymphoma, and infection. Apart from known untreated chronic hepatitis C, all infectious, autoimmune and hypercoagulability work-ups were negative. Biopsies of the liver and iliac bone lesions showed areas of benign-appearing vascular proliferation in a background of fibrosis. The vascular endothelial cells were positive for CD34 and CD31 but negative for D2-40. On follow-up approximately eight months later, the patient was asymptomatic.
Results (if a Case Study enter NA)
NA
Conclusion
Liver involvement by cystic angiomatosis is exceedingly rare and has been associated with increased mortality. This case provides an example of a patient with incidentally discovered cystic angiomatosis involving liver, spleen, and bone who remains asymptomatic at follow-up. Additional cases are required to understand the pathophysiology and disease course in this group of patients, and to investigate possible therapeutic targets.

Abstract
The murine 3T3-L1 pre-adipocyte cell line is widely used as an in vitro model for adipogenesis because of its similarities to primary fat cells. The aim of this study was to investigate the intracellular mechanisms by which skimmed milk fermented by two lactic acid bacteria (LAB), Enterococcus faecalis and Lactobacillus plantarum, inhibited the differentiation of 3T3-L1 pre-adipocytes. Skimmed milk fermented by both LAB, but not non-fermented skimmed milk, significantly reduced the accumulation of lipid droplets and cellular triglycerides in a concentration-dependent manner. The mRNA and protein levels of peroxisome proliferator-activated receptor γ (PPARγ) were markedly inhibited in the presence of skimmed milk fermented by both LAB. Furthermore, the skimmed milk fermented by both LAB decreased the mRNA and protein expressions of PPARγ-targeting genes, lipoprotein lipase and adipocyte fatty acid-binding protein. Under the same circumstances, resistin mRNA expression was downregulated, but not leptin mRNA expression. In contrast, skimmed milk fermented by both LAB significantly upregulated tumor necrosis factor-α (TNF-α). These results suggest that LAB-fermented skimmed milk inhibits adipogenesis by inhibiting a master transcription factor PPARγ via the upregulation of the proinflammatory cytokine TNF-α in 3T3-L1 cells.

Abstract
UNLABELLED In a multi-site longitudinal cohort study, decreasing hemoglobin was associated with increased hip fracture risk in men. Anemia was associated with hip fracture in men and in African American women. Decreasing hemoglobin may be a marker of progressing bone fragility, making its serial measurement useful for fracture risk stratification. INTRODUCTION Hematopoiesis and bone health are interdependent. Anemia has been associated with risk of fracture in humans. To further elucidate this relationship, we hypothesized that decreasing hemoglobin could indicate defective hematopoiesis and would also predict fracture risk. METHODS We performed a prospective analysis from study baseline (1992) of the Cardiovascular Health Study, a multi-site longitudinal cohort study. A total of 4670 men and women, ages >65 years, who were able to consent and not institutionalized or wheelchair bound, had hemoglobin (Hb) measured in 1992. For 4006 subjects, Hb change from 1989 to 1992 was annualized and divided into sex-specific quartiles. Incident hip fractures were verified against Medicare claims data during a median follow-up of 11.8 years. RESULTS Nested Cox proportional-hazard models estimated association of hip fracture with anemia (men Hb <13 g/dL, women Hb <12 g/dL) and separately, greatest Hb decrease (versus others). Anemia was associated with increased hip fracture risk in all men (HR 1.59; 95% CI 1.01-2.50) and African American women (HR 3.21; 95% CI 1.07-9.63). In men, an annualized Hb loss of >0.36 g/dL/year was associated with a higher risk of hip fracture (HR 1.67; 95% CI 1.10-2.54), which was lessened by anemia at the start of fracture follow-up (HR 1.53; 95% CI 0.99-2.39). CONCLUSIONS Decreasing Hb may be an early marker for subsequent hip fracture risk in men, which may be less informative once an anemia threshold is crossed. Only African American women with anemia had increased hip fracture risk, suggesting a race difference in this relationship.

Abstract
BACKGROUND AND PURPOSE The safety and efficacy of tirofiban during endovascular therapy in patients undergoing intravenous thrombolysis with recombinant IV tPA remain unclear. This study aimed to investigate the safety and efficacy of intra-arterial tirofiban use during endovascular therapy in patients treated with IV tPA. MATERIALS AND METHODS Using a multicenter registry, we enrolled patients with acute ischemic stroke who underwent endovascular therapy. Safety outcomes included postprocedural parenchymal hematoma type 2 and/or thick subarachnoid hemorrhage, intraventricular hemorrhage, and 3-month mortality. Efficacy outcomes included the successful reperfusion rate, postprocedural reocclusion, and good outcomes at 3 months (mRS scores of 0-2). The tirofiban effect on the outcomes was evaluated using a multivariable analysis while adjusting for potential confounders. RESULTS Among enrolled patients, we identified 314 patients with stroke (279 and 35 patients in the no tirofiban and tirofiban groups, respectively) due to an intracranial artery occlusion who underwent endovascular therapy with intravenous thrombolysis. A multivariable analysis revealed no association of intra-arterial tirofiban with postprocedural parenchymal hematoma type and/or thick subarachnoid hemorrhage (adjusted OR, 1.07; 95% CI, 0.20-4.10; P = .918), intraventricular hemorrhage (adjusted OR, 0.43; 95% CI, 0.02-2.85; P = .467), and 3-month mortality (adjusted OR, 0.38; 95% CI, 0.04-1.87; P = .299). Intra-arterial tirofiban was not associated with good outcome (adjusted OR, 2.22; 95% CI, 0.89 -6.12; P = .099). CONCLUSIONS Using intra-arterial tirofiban during endovascular therapy after IV tPA could be safe.

Abstract
The antibiofilm effect of bacteriocin-like inhibitory substance (BLIS) from Enterococcus faecium DB1 against Clostridium perfringens was investigated in the present study. BLIS of E. faecium DB1 significantly reduced biofilm formation by C. perfringens in a dose-dependent manner for 24 and 48 h. In particular, treatment with BLIS of E. faecium DB1 significantly inhibited biofilm formation by C. perfringens on chicken meat and stainless steel coupon surfaces. Moreover, BLIS of E. faecium DB1 decreased the viability of C. perfringens biofilm and planktonic cells, indicating that the reduction of biofilm formation by C. perfringens might be achieved by killing the bacterial cells. Taken together, the present results suggest that BLIS of E. faecium DB1 can be a promising antibiofilm agent to eradicate C. perfringens.

Background/Introduction: Left atrial (LA) wall stress (LAW-str) may contribute to the mechanism of atrial fibrillation (AF).
Purpose
We explored the clinical characteristics and the rhythm outcome of AF depending on LAW-str among the patients who underwent AF catheter ablation (AFCA). We also tested whether artificial intelligence (AI) properly estimate LAW-str without invasive parameters.
Methods
We included 2223 patients (72.8% male, 59.0 [52.0–67.0] years old, 28.7% with persistent AF [PeAF]) who underwent radiofrequency catheter ablation (RFCA). LAW-str was calculated by the Law of Laplace using LA diameter (echocardiogram), peak LA pressure, and mean LA wall thickness (computed tomography) measured by customized software. Based on the quartile (Q1–4) or AI-estimated values of LAW-str, we compared clinical characteristics and rhythm outcome.
Results
LAW-str was independently associated with PeAF (p < 0.001), diabetes (p = 0.012) and vascular disease (p = 0.002), body mass index (p < 0.001), E/Em (p < 0.001), and mean LA voltage (p < 0.001). During 26.0 (12.0–52.0) months follow-up, clinical recurrence of AF was significantly higher in the Q4 of LAW-str group (log rank p = 0.001). LAW-str was independently associated with clinical recurrence after AFCA (HR 1.001 [1.000–1.002], p = 0.013). AI-based model using non-invasive parameters predicted Q4 of LAW-str with area under the curve (AUC) 0.734, which was similar to logistic regression based predictive model using all data including invasive parameters (AUC 0.726). Patients in Q4 of LAW-str showed consistently worse rhythm outcome regardless of the type of AF, sex, or AI-based prediction (p = 0.039).
Conclusions
The LAW-str seems to be associated with rhythm outcome of AFCA and AI can predict this complex parameter with moderate accuracy.

Abstract
Improving materials used to make qubits is crucial to further progress in quantum information processing. Of particular interest are semiconductor-superconductor heterostructures that are expected to form the basis of topological quantum computing. We grew semiconductor indium antimonide nanowires that were coated with shells of tin of uniform thickness. No interdiffusion was observed at the interface between Sn and InSb. Tunnel junctions were prepared by in situ shadowing. Despite the lack of lattice matching between Sn and InSb, a 15-nanometer-thick shell of tin was found to induce a hard superconducting gap, with superconductivity persisting in magnetic field up to 4 teslas. A small island of Sn-InSb exhibits the two-electron charging effect. These findings suggest a less restrictive approach to fabricating superconducting and topological quantum circuits.

Abstract
SETTING: Multicentre retrospective study in South Korea.OBJECTIVE: To longitudinally evaluate changes in lung volume and diffusing capacity for carbon monoxide (DLCO) with forced expiratory volume in 1 sec (FEV1).DESIGN: A total of 155 patients with chronic obstructive pulmonary disease (COPD), whose pulmonary function parameters were measured annually for 5 years, were selected from a prospective cohort in South Korea. A random coefficients model was used to estimate mean annual FEV1, lung volume parameter and DLCO change rates.RESULTS: Patients were classified into four groups based on baseline DLCO and residual volume/total lung capacity (RV/TLC) measurements. The annual FEV1 decline rate was greater in patients with low DLCO than in those with normal DLCO, with the greatest decline occurring in patients with low DLCO and normal RV/TLC. RV and RV/TLC declined in patients with high RV/TLC, whereas these increased in patients with normal RV/TLC. DLCO decreased longitudinally in all four groups, with the greatest decline occurring in patients with normal DLCO and normal RV/TLC.CONCLUSIONS: Different subgroups of patients with COPD exhibited distinctive pulmonary function change patterns. Baseline DLCO and RV/TLC may be used as physiological markers to predict long-term changes in pulmonary function.

Abstract
Alcohol use disorder (AUD) is a chronic relapsing disorder characterized by an impaired ability to control or stop alcohol intake and is associated with organ damage including alcohol-associated liver disease (ALD) and progressive neurodegeneration. The etiology of AUD is complex, but organ injury due to chronic alcohol use can be partially attributed to systemic and local inflammation along the gut-liver-brain axis. Excessive alcohol use can result in translocation of bacterial products into circulation, increased expression of pro-inflammatory cytokines, and activation of immune cells, including macrophages and/or microglia in the liver and brain. One potential mediator of this alcohol-induced inflammation is proprotein convertase subtilisin/kexin type 9 (PCSK9). PCSK9 is primarily known for its regulation of plasma low-density lipoprotein cholesterol but has more recently been shown to influence inflammatory responses in the liver and brain. In rodent and post-mortem brain studies, chronic alcohol use altered methylation of the PCSK9 gene and increased expression of PCSK9 in the liver and cerebral spinal fluid. Additionally, PCSK9 inhibition in a rat model of ALD attenuated liver inflammation and steatosis. PCSK9 may play an important role in alcohol-induced pathologies along the gut-liver-brain axis and may be a novel therapeutic target for AUD-related liver and brain inflammation.

Abstract
Biotransformation, the structural modification of chemical compounds, has proved to be an indispensable tool in providing beneficial health effects. Although the health benefits of biotransformation using plant sources has been widely studied, the anti-adipogenic effect of biotransformed dairy products, such as whey, have not yet been demonstrated. Here, we investigated the anti-adipogenic effect of whey biotransformed by Weissella cibaria in 3T3-L1 adipocytes. Weissella cibaria-biotransformed whey considerably reduced the accumulation of lipid droplets and intracellular triglycerides in 3T3-L1 cells. In the presence of W. cibaria-biotransformed whey, the mRNA and protein expression of a key transcription factor, peroxisome proliferator-activated receptor γ (PPARγ), for adipogenesis was markedly suppressed in 3T3-L1 cells. Additionally, W. cibaria-biotransformed whey also decreased the mRNA and protein expressions of lipoprotein lipase and adipocyte fatty acid-binding protein, which are regulated by PPARγ. Moreover, W. cibaria-biotransformed whey inhibited the expression of adipokines, resistin, and leptin. Collectively, these results suggest that whey biotransformed by W. cibaria has the potential to exert anti-adipogenic effects by inhibiting intracellular signaling events of adipogenic-related transcription factors and target genes.

Abstract
Microbial bioconversion using lactic acid bacteria (LAB) provides several human
health benefits. Although whey and whey-derived bioactive compounds can
contribute to an improvement in human health, the potential anti-obesity effect
of whey bioconversion by LAB has not been well studied. This study aimed to
investigate whether bioconversion of whey by Pediococcus
pentosaceus KI31 and Lactobacillus sakei KI36
(KI31-W and KI36-W, respectively) inhibits 3T3-L1 preadipocyte differentiation.
Both KI31-W and KI36-W reduced intracellular lipid accumulation significantly,
without decreasing 3T3-L1 preadipocyte proliferation. In addition,
obesity-related transcription factor (peroxisome proliferator-activated receptor
γ) and genes (adipocyte fatty acid-binding protein and lipoprotein
lipase) were down-regulated significantly in 3T3-L1 cells in the presence of
KI31-W and KI36-W. Collectively, these results suggest that bioconversion of
whey by LAB exhibits anti-adipogenic activity and may be applied as a
therapeutic agent for obesity.

Abstract
Interventions addressing syndemics and ART adherence are needed for individuals with uncontrolled HIV and psychosocial problems. Twenty-seven participants with detectable HIV plasma viral load (PVL) or recent STI participated in an open trial of transdiagnostic adherence counseling and cognitive behavioral therapy. Outcomes were collected at baseline, 4-, and 8-months. Log PVL improved from baseline to 4-month (γ = - 1.13, 95% CI - 1.72, - 0.55, p < 0.001) and 8-month (γ = - 0.93, 95% CI - 1.57, - 0.30, p = 0.006), with more participants suppressed at 4- (χ2(1) = 9.09, p = 0.001) and 8-month (χ2(1) = 5.14, p = 0.016). Self-reported adherence improved across major assessments (γ = 0.87, 95% CI 0.28, 1.46, p = .005); Wisepill adherence did not. Negative affect declined during treatment (γ = - 0.28, 95% CI - 0.40, - 0.16, p < 0.001), with improvement at 4- (γ = - 4.34, 95% CI - 6.99, - 1.69, p = 0.002) but not 8-month. Positive affect trended positively during treatment and from baseline to 4-month, with significant 8-month improvement (γ = 3.84, 95% CI 0.33, 7.44, p = 0.04). Depressive symptoms did not change. In a complicated sample of participants selected for uncontrolled HIV, the intervention yielded improved PVL and self-reported adherence. Efforts to end HIV should improve upon strategies such as these, addressing syndemics. Registration: clinicaltrial.gov: NCT02696681.

Abstract
In this study, we identified the genome sequence of the novel virus Pistacia-associated flexivirus 1 (PAFV1), a putative member of the mycovirus family Gammaflexiviridae (the order Tymovirales), via analysis of a transcriptome dataset for the mastic tree (Pistacia lentiscus, the family Anacardiaceae). PAFV1 was predicted to have three open reading frames (ORFs): ORF1, encoding a replicase (REP) with RNA-dependent RNA polymerase activity; ORF2, a movement protein (MP); and ORF3, a hypothetical protein. The PAFV1 REP sequence showed high similarity to those of three known members of the family Gammaflexiviridae i.e., Entoleuca gammaflexivirus 1 (EnFV1), Entoleuca gammaflexivirus 2 (EnFV2), and Botrytis virus F (BVF). A genome contig of the fungus Monosporascus cannonballus also contained a sequence of an endogenous virus similar to that of PAFV1. Sequence comparison and phylogenetic analysis indicated that PAFV1, EnFV1, and the endogenous virus of M. cannonballus formed a distinct subgroup (apart from EnFV2 and BVF), and may be the founding members of a novel genus in the family Gammaflexiviridae. Notably, MP sequences of PAFV1/EnFV1 showed similarity to the MP sequences of the mycovirus group called tobamo-like mycoviruses (an unassigned taxon), implying that genomic recombination occurred between members of the family Gammaflexiviridae and tobamo-like mycoviruses. Since PAFV1 is phylogenetically related to mycoviruses, PAFV1 may also be a mycovirus that infected a fungus associated with the mastic tree sample, which is evidenced by the presence of fungal ribosomal RNA sequences in the mastic tree transcriptome. Thus, the PAFV1 genome sequence may be useful in elucidating the genome evolution of Gammaflexiviridae and tobamo-like mycoviruses. Keywords: Pistacia-associated flexivirus 1; Gammaflexiviridae; mycovirus, mastic tree.

Abstract
PURPOSE Standard treatment for retained products of conception (RPOC) is dilation and curettage (D&C), however, this brings a risk of intrauterine synechiae and subsequent fertility issues. A treatment strategy to avoid D&C is medical management with misoprostol. The justification for misoprostol in this setting is extrapolated from miscarriage and termination literature, however, no studies have looked specifically in the setting of RPOC. The purpose of this study is to determine the efficacy of misoprostol as definitive management of RPOC. MATERIALS AND METHODS A retrospective cohort study was conducted from January 2016 to March 2017 at an Early Pregnancy Assessment Clinic. Patients diagnosed with RPOC with clinical symptoms and ultrasound findings of endometrial mass and/or doppler flow treated expectantly, medically with vaginal misoprostol or with a suction D&C underwent a chart review. Primary outcome was resolution of RPOC without surgical intervention. RESULTS AND CONCLUSIONS Of 1743 unique pregnancies, 189 women were diagnosed with RPOC. 34% (65/178) chose misoprostol for management of RPOC. Baseline demographics between the three treatment modalities (expectant, medical, surgical) were comparable. 65% (42/65) of patients who took misoprostol avoided D&C. Misoprostol is most effective (76%) in the setting of RPOC if the primary treatment for miscarriage was expectant management, with less success with primary medical management (44%) and primary surgical management (40%).

Abstract
INTRODUCTION Endoscopically assisted malarplasty with a greenstick fracture is a method for preserving the body eminence and improving arch protrusion. However, this technique is inadequate when malar body reduction is required. To compensate for these limitations, we developed a new surgical technique using the endoscope to reduce body protrusion. MATERIAL AND METHODS We enrolled 261 patients who visited our clinic for zygoma reduction from January 2017 to December 2018. Their mean age was 31 (range 17-63) years. After a scalp incision, an incomplete osteotomy was created from the most prominent portion of the zygoma body to the zygomaticomaxillary suture line. A complete osteotomy was performed on the arch. These osteotomies resulted in an L-shaped zygoma segment after tapping the bone with a mallet. RESULTS Of the 261 patients who underwent our L-rotation technique, 242 also received a corticotomy. Of those patients, 15 underwent a different degree of zygoma reduction on both sides. A floating zygomatic segment occurred in four cases, although no further surgery was required. One patient's zygomatic segment dropped on one side, requiring rigid fixation through the intraoral approach. Most patients were satisfied and there were no specific complications. CONCLUSIONS Endoscopically assisted malarplasty using an L-rotation technique enables the protrusion of both the arch and body to be reduced. The zygoma reduction can be modified based on the location of the incomplete osteotomoy line and the number of corticotomies required.

Abstract
Screening measures for depression developed in high-income countries have not always demonstrated strong psychometric properties in South Africa and with people living with HIV (PLWH). The present study explored the psychometric properties of the 16-item South African Depression Scale (SADS) comprised of idioms of distress specific to isiXhosa culture in PLWH. The SADS was administered to 137 Xhosa-speaking PLWH who met diagnostic criteria for major depressive disorder (MDD) together with the Hamilton Depression Scale (HAM-D) and the Center for Epidemiological Studies Depression Scale (CES-D). We conducted exploratory factor analysis, correlation, and reliability statistics. Four factors of the SADS emerged: Sadness, lethargy/burdened, anhedonia/withdrawal, and cognitive/somatic. All factors correlated significantly with the HAM-D and CES-D. Internal consistency of the overall measure was high (α = .89). The SADS promises to be a robust measure of depression in isiXhosa-speaking PLWH in South Africa likely due to the inclusion of local idioms of distress.

Abstract
OBJECTIVES Alcohol is one of the most used and abused psychoactive substances by adolescents. We investigated influencing factors of risky and problem drinking in Korean female adolescents. STUDY DESIGN The study design used is a cross-sectional modeling. METHODS We used data from the 13th Korean Youth Risk Behavior Web-based Survey (KYRBS) conducted in 2017. KYRBS data were obtained from a stratified, multistage, clustered sample. Risky drinking was binge drinking and problem drinking was drinking with several conflicts association with alcohol consumption. RESULTS Among 62,276 participants, the rates of current, risky, and problem drinking among all participants were 16.1%, 8.3%, and 6.1%, respectively. Although all of these rates were higher in males, risky and problem drinking rates among current female drinkers were higher than those of males (55.4 vs 48.5%, 38.9 vs 37.2%, respectively). Problem drinking was most strongly associated with risky drinking (adjusted odds ratio: 17.53 [95% confidence interval: 14.63-21.00]), similarly, risky drinking was most strongly associated with problem drinking in female current drinkers (17.76 [14.84-21.27]). Current smoking was the second strongest risk factor for risky and problem drinking in females (5.22 [3.92-6.95] and 2.93 [2.21-3.89], respectively). CONCLUSION Many female adolescents in Korea drink alcohol in an unhealthy manner. The female risky and problem drinking rates among current drinkers were higher than those of males. Risky drinking and problem drinking was most significant influencing factor among females, reciprocally. Public education on abstinence in female adolescents is warranted.

Abstract
BACKGROUND Japan has experienced a low prevalence of childhood obesity. The Japanese nationwide school lunch program is suggested to have helped this phenomenon, but it has not been proven. METHODS From official statistics, we combined annual data for 2006-15 about the prefecture-level school lunch coverage rate for public junior high school students and the prefecture-level nutritional indicators calculated by randomly selected age-sex groups of 13-15-year olds: the percentage of overweight, obese or underweight children, who are 20% heavier, 30% heavier or 20% lighter than the standard weight by sex, age and height; and mean body weight (kg) or height (cm). We estimated the impact of the school lunch coverage rate on the nutritional indicators in subsequent years, adjusting for the lagged dependent variable and dummies for prefecture, age and year. RESULTS A 10 percentage point increase in the prefecture-level school lunch coverage rate significantly decreased the percentage of overweight (0.37%, 95% CI: 0.18-0.56) and obesity (0.23%, 0.10-0.37) in subsequent years among boys, but not among girls. No significant effect on the percentage of underweight or mean body weight/height was observed for either sex. CONCLUSIONS Appropriate nutritional intake through school lunch may be effective to reduce childhood obesity.

Abstract
Endoscopic sinus surgery (ESS) is widely used as standard surgical treatment for chronic rhinosinusitis. Orbital complications of varying degrees occurred during ESS have been widely reported. If the orbital symptoms occurred immediately after surgery, ocular damage associated with surgery is suspected if the patient’s preoperative ocular function was patent. If immediate action is not taken, permanent visual loss might develop, so it is very important to diagnose orbital complications and take appropriate action. In our case, there was no definite intraorbital hemorrhage when sudden visual loss was noted. The symptoms were fully recovered without further treatment and it is clinically suspected to be caused by transient ocular muscle toxicity of local anesthetics.

Abstract
BACKGROUND Nearly all publications related to endoscopic treatment of biliary anastomotic stricture after liver transplant have reported cases that can be cannulated. However, very few publications discuss endoscopic treatment of biliary anastomotic stricture (BAS) in which the guide wire does not pass through the stricture site. The purpose of this article is to analyze the long-term outcome of the Rendezvous technique in severe strictures through which guide wires cannot cannulate. METHODS Between 2010 and 2017, a total of 29 patients who underwent Rendezvous technique because of severe BAS after liver transplant were included in the study. RESULTS Twenty-nine patients who underwent the Rendezvous technique showed a 100% technical success rate. Ten patients (34.4%) required stent removal; the mean stenting period was 14.9 (SD, 5.6) months (range, 6.65-24.14 months). A total of 19 patients were maintained without stent removal; the stent-maintaining period was 13.1 (SD, 8.4) months (range, 3.48-38.61 months). Two patients receiving left lobe grafts maintained the stents for 27.1 (SD, 16.2) months. In left lobe graft, the duct anastomosis position moves to the right posteroinferior side of the patient. CONCLUSIONS Our results suggest that the stenting period of the Rendezvous technique was longer in severe BAS than in cannulated endoscopic retrograde cholangiopancreatography cases. Especially in the left liver, the position of the duct anastomosis changed to the right posteroinferior of the patient. Thus, the donor duct and the recipient duct are angulated, kinking worsens, and the stenting period becomes longer.

Abstract
OBJECTIVE Smoking is an important causative factor of chronic obstructive pulmonary disease (COPD), and females are considered more susceptible to the effects of smoking than males. However, in previous Korean studies, the effects of sex differences on the association between smoking and COPD have been controversial. In this study, the effects of sex differences on the association between smoking and COPD and the effects of female hidden smokers on that association in Korean adults were investigated. METHODS Data were acquired from the Korea National Health and Nutrition Examination Surveys (KNHANES). RESULTS The multivariate logistic regression analysis showed that self-reported smoking status for ex-smoker and current smoker correlated with COPD (odds ratio, OR: 1.67 and OR: 2.41, respectively). Self-reported smoking status for ex-smoker and current smoker correlated with COPD in men (OR: 1.61, OR: 2.43, respectively). Female self-reported current smoking status correlated with COPD (OR: 2.52), but female ex-smoker status was not significantly correlated with COPD. The ratios of cotinine-verified to self-reported smoking rates were 1.95 for women and 1.07 for men. CONCLUSION The results of this study were that sex differences might affect the association between COPD and smoking and that female hidden smoking might affect the association between smoking and COPD in Korean adults.

Abstract
BACKGROUND AND PURPOSE This work investigated alterations in functional connectivity (FC) and associated structures in patients with Angelman syndrome (AS) by using integrated quantitative imaging analysis and connectivity measures. MATERIALS AND METHODS We obtained 3T brain MR imaging, including resting-state functional MR imaging, diffusion tensor imaging, and 3D T1-weighted imaging from children with AS (n = 14) and age- and sex-matched controls (n = 28). The brains of patients with AS were analyzed by measuring FC, white matter microstructural analysis, cortical thickness, and brain volumes; these were compared with brains of controls. RESULTS Interregional FC analysis revealed significantly reduced intra- and interhemispheric FC, especially in the basal ganglia and thalamus, in patients with AS. Significant reductions in fractional anisotropy were found in the corpus callosum, cingulum, posterior limb of the internal capsules, and arcuate fasciculus in patients with AS. Quantitative structural analysis also showed gray matter volume loss of the basal ganglia and diffuse WM volume reduction in AS compared with the control group. CONCLUSIONS This integrated quantitative MR imaging analysis demonstrated poor functional and structural connectivity, as well as brain volume reduction, in children with AS, which may explain the motor and language dysfunction observed in this well-characterized neurobehavioral phenotype.

Abstract
Objective: We evaluated the validity of a newly developed mobile application (i.e. the Weighing Cam) for pediatric weight estimation compared with that of the Broselow tape. Methods: We developed an application that estimates the weight of pediatric patients using a smartphone camera and displays the drug dosage, device size, and defibrillation energy on the screen of the smartphone. We enrolled a convenience sample of pediatric patients aged <16 years who presented at two pediatric emergency departments of two tertiary academic hospitals in South Korea. The pediatric patients' heights and weights were measured; then, one researcher estimated the weights using the application. Using the measured height, we determined the weight estimated by the Broselow tape. We compared the estimated measurements by determining the mean percentage error (MPE), mean absolute percentage error, root mean square percentage error, and percentages predicted within 10% and 20% of the actual. Results: In total, 480 patients were enrolled in 16 age categories, each with 15 males and 15 females of different ages. The Weighing Cam demonstrated a lower bias (mean difference: -1.98% [95% confidence interval -2.91% to -1.05%] for MPE) and a higher proportion of estimated weights within 10% of the actual weights than the Broselow tape (mean difference: 9.1% [95% confidence interval 3.0% to 15.1%]). The Weighing Cam showed better performance in terms of accuracy and precision than the Broselow tape in all subgroups stratified by age or body mass index percentile. Conclusions: The Weighing Cam may estimate pediatric patients' weights more accurately than the Broselow tape. The Weighing Cam may be useful for pediatric resuscitation in both prehospital and hospital settings.
