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
(1) Background: The aim of this study was to compare the survival benefit of radical antegrade modular pancreatosplenectomy (RAMPS) with conventional distal pancreatosplenectomy (cDPS) in left-sided pancreatic cancer. (2) Methods: A retrospective propensity score matching (PSM) analysis was conducted on 333 patients who underwent RAMPS or cDPS for left-sided pancreatic cancer at four tertiary cancer centers. The study assessed prognostic factors and compared survival and operative outcomes. (3) Results: After PSM, 99 patients were matched in each group. RAMPS resulted in a higher retrieved lymph node count than cDPS (15.0 vs. 10.0, p < 0.001). No significant differences were observed between the two groups in terms of R0 resection rate, blood loss, hospital stay, or morbidity. The 5-year overall survival rate was similar in both groups (cDPS vs. RAMPS, 44.4% vs. 45.2%, p = 0.853), and disease-free survival was also comparable. Multivariate analysis revealed that ASA score, preoperative CA19-9, histologic differentiation, R1 resection, adjuvant treatment, and lymphovascular invasion were significant prognostic factors for overall survival. Preoperative CA19-9, histologic differentiation, T-stage, adjuvant treatment, and lymphovascular invasion were independent significant prognostic factors for disease-free survival. (4) Conclusions: Although RAMPS resulted in a higher retrieved lymph node count, survival outcomes were not different between the two groups. RAMPS was a surgical option to achieve R0 resection rather than a standard procedure.

Abstract
CONTEXT With advancements in long-term survival after pancreatectomy, post-pancreatectomy diabetes has become a concern, and the risk factors are not established yet. Pancreatic islets are susceptible to ischemic damage, though there is a lack of clinical evidence regarding glycemic deterioration. OBJECTIVE To investigate association between hypotension during pancreatectomy and development of post-pancreatectomy diabetes. DESIGN In this retrospective, longitudinal cohort study, we enrolled patients without diabetes who underwent distal pancreatectomy or pancreaticoduodenectomy between January 2005 and December 2018, from two referral hospitals in Korea. MAIN OUTCOME MEASURES Intraoperative hypotension [IOH] was defined as a 20% or greater reduction in systolic blood-pressure. The primary and secondary outcomes were incident diabetes and postoperative Homeostatic Model Assessment [HOMA] indices. RESULTS We enrolled 1,129 patients (average age, 59 years; 49% men; 35% distal pancreatectomy). IOH occurred in 83% (median duration, 25 minutes; interquartile range [IQR], 5-65). During a median follow-up of 3.9 years, diabetes developed in 284 patients (25%). The cumulative incidence of diabetes was proportional to increases in the duration and depth of IOH (P < 0.001). For the median duration in an IOH when compared to a reference time of 0 minute, the hazard ratio [HR] was 1.48 (95% CI, 1.14-1.92). The effect was pronounced with distal pancreatectomy compared to pancreaticoduodenectomy. Furthermore, the duration of IOH was inversely correlated with 1-year HOMA beta-cell function (P < 0.002), but not with HOMA insulin resistance. CONCLUSIONS These results support the hypothesis that IOH during pancreatectomy may elevate risk of diabetes by inducing beta cell insufficiency.

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
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
Background/Aims : Recently, patients with pancreatic cancer (PC) who underwent resection have exhibited improved survival outcomes, but comprehensive analysis is limited. We analyzed the trends of contributing factors. Methods : Data of patients with resected PC were retrospectively collected from the Korean Health Insurance Review and Assessment Service (HIRA) database and separately at our institution. Cox regression analysis was conducted with the data from our institution a survival prediction score was calculated using the β coefficients. Results : Comparison between the periods 2013-2015 (n=3,255) and 2016-2018 (n=3,698) revealed a difference in the median overall survival (25.9 months vs not reached, p<0.001) when analyzed with the HIRA database which was similar to our single-center data (2013-2015 [n=119] vs 2016-2018 [n=148], 20.9 months vs 32.2 months, p=0.003). Multivariable analyses revealed six factors significantly associated with better OS, and the scores were as follows: age >70 years, 1; elevated carbohydrate antigen 19-9 at diagnosis, 1; R1 resection, 1; stage N1 and N2, 1 and 3, respectively; no adjuvant treatment, 2; FOLFIRINOX or gemcitabine plus nab-paclitaxel after recurrence, 4; and other chemotherapy or supportive care only after recurrence, 5. The rate of R0 resection (69.7% vs 80.4%), use of adjuvant treatment (63.0% vs 74.3%), and utilization of FOLFIRINOX or gemcitabine plus nab-paclitaxel (25.2% vs 47.3%) as palliative chemotherapeutic regimen, all increased between the two time periods, resulting in decreased total survival prediction score (mean: 7.32 vs 6.18, p=0.004). Conclusions : Strict selection of surgical candidates, more use of adjuvant treatment, and adoption of the latest combination regimens for palliative chemotherapy after recurrence were identified as factors of recent improvement.

Abstract
BACKGROUND Hepatic artery obstruction is a critical consideration in graft outcomes after living donor liver transplantation. We report a case of diffuse arterial vasospasm that developed immediately after anastomosis and was managed with an intra-arterial infusion of lipo-prostaglandin E1 (PGE1). CASE SUMMARY A 57-year-old male with hepatitis B virus-related liver cirrhosis and hepatocellular carcinoma underwent ABO-incompatible living donor liver transplant. The grafted hepatic artery was first anastomosed to the recipient's right hepatic artery stump. However, the arterial pulse immediately weakened. Although a new anastomosis was performed using the right gastroepiploic artery, the patient's arterial pulse rate remained poor. We attempted angiographic intervention immediately after the operation; it showed diffuse arterial vasospasms like 'beads on a string'. We attempted continuous infusion of lipo-PGE1 overnight via an intra-arterial catheter. The next day, arterial flow improved without any spasms or strictures. The patient had no additional arterial complications or related sequelae at the time of writing, 1-year post-liver transplantation. CONCLUSION Angiographic evaluation is helpful in cases of repetitive arterial obstruction, and intra-arterial infusion of lipo-PGE1 may be effective in treating diffuse arterial spasms.

Abstract
Background Since laparoscopic anatomical resection (LAR) for tumors, especially located in the posterosuperior (PS) segments of the liver remains difficult, laparoscopic non-anatomical resection (LNAR) are generally preferred. To compare the clinical outcomes between LAR and LNAR for hepatocellular carcinoma (HCC) located in the PS segments. Methods We retrospectively reviewed the data for 1,029 patients who underwent hepatectomy for HCC between 2004 and 2019. Of 167 patients who underwent laparoscopic hepatectomy for HCC in PS segments, 64 underwent LNAR and 103 underwent LAR. Patients were matched one-to-one using propensity score matching (46:46). Results LNAR was associated with significantly shorter operation time (P=0.001), lower estimated blood loss (P=0.001), lower transfusion rate (P=0.006) and shorter hospital stay (P=0.012) than LAR. The respective 1- ,3-, and 5-year overall survival rates (LAR: 95.3%, 87.1%, and 77.8%; LNAR: 96.7%, 91.6%, and 85.0%; P=0.262) and recurrence-free survival rates (LAR: 75.7%, 70.3%, and 68.9%; LNAR: 81.8%, 58.3%, and 55.3%; P=0.879) were similar. The intrahepatic recurrence rate was significantly higher in LNAR group than in LAR group (78.6% vs. 57.1%, P=0.023), but the post-recurrence treatments differed significantly between the two groups (P=0.016); the re-resection rate was much greater in the LNAR group (45.0% vs. 0%) group. The respective 1-, 3-, and 5-year post-recurrence survival rates were similar in the LAR and LNAR groups (P=0.212). After recurrence, survival in re-resection group was significantly greater than not (P=0.026). Conclusions LNAR is safe and feasible for HCC located in PS segments, and provided acceptable oncologic outcomes that are comparable to those of LAR. LNAR can be considered for patient with tumor located in PS segment when LAR is not feasible.

Abstract
OBJECTIVE This study aimed to evaluate the effect of liver resection on the prognosis of T2 gallbladder cancer (GBC). BACKGROUND Although extended cholecystectomy [lymph node dissection (LND) + liver resection] is recommended for T2 GBC, recent studies have shown that liver resection does not improve survival outcomes relative to LND alone. METHODS Patients with pT2 GBC who underwent extended cholecystectomy as an initial procedure and did not reoperation after cholecystectomy at 3 tertiary referral hospitals between January 2010 and December 2020 were analyzed. Extended cholecystectomy was defined as either LND with liver resection (LND+L group) or LND only (LND group). We conducted 2:1 propensity score matching to compare the survival outcomes of the groups. RESULTS Of the 197 patients enrolled, 100 patients from the LND+L group and 50 from the LND group were successfully matched. The LND+L group experienced greater estimated blood loss ( P <0.001) and a longer postoperative hospital stay ( P =0.047). There was no significant difference in the 5-year disease-free survival (DFS) of the 2 groups (82.7% vs 77.9%, respectively, P =0.376). A subgroup analysis showed that the 5-year DFS was similar in the 2 groups in both T substages (T2a: 77.8% vs 81.8%, respectively, P =0.988; T2b: 88.1% vs 71.5%, respectively, P =0.196). In a multivariable analysis, lymph node metastasis [hazard ratio (HR) 4.80, P =0.006] and perineural invasion (HR 2.61, P =0.047) were independent risk factors for DFS; liver resection was not a prognostic factor (HR 0.68, P =0.381). CONCLUSIONS Extended cholecystectomy including LND without liver resection may be a reasonable treatment option for selected T2 GBC patients.

Abstract
BACKGROUND Postpancreatectomy hemorrhage (PPH) is the most feared complication after pancreaticoduodenectomy (PD). The most common cause is erosion of the gastroduodenal artery stump. Preventive measures have been previously reported, but a consensus is lacking. The aim of this study was to analyze the preventive effect of reinforcing the hepatic artery using a polyglycolic acid (PGA) sheet during PD. METHODS A multicenter retrospective study was performed, collecting data from three tertiary hospitals in Korea. Patients receiving PD from January 2016 to December 2021 were included. The primary endpoint was rate of PPH from the hepatic artery. Arterial reinforcement (AR) was performed by wrapping the artery with Neoveil (Gunze Ltd) and applying fibrin glue. The perioperative data of patients who did not receive AR were compared with data of those who received AR. RESULTS A total of 904 patients were analyzed. The rate of PPH from the hepatic artery was significantly lower in the AR group. (3.5% vs 0.7%, p = .002) In patients with CR-POPF, the 90 day mortality rate of the AR group was less than half that of the non-AR group (7.2% vs 3.5%, p = .455) Risk factor analysis showed CR-POPF to be an independent risk factor for PPH. Arterial reinforcement was shown to be a strong protective factor for PPH (OR 0.20, 95% CI: 0.05-0.72, p = .014). CONCLUSIONS AR of the hepatic artery using Neoveil and fibrin glue is a simple method that greatly reduces the rate of PPH after PD.

Abstract
BACKGROUND Older adults are at an increased risk of postoperative morbidity. Numerous risk stratification tools exist, but effort and manpower are required. OBJECTIVE This study aimed to develop a predictive model of postoperative adverse outcomes in older patients following general surgery with an open-source, patient-level prediction from the Observational Health Data Sciences and Informatics for internal and external validation. METHODS We used the Observational Medical Outcomes Partnership common data model and machine learning algorithms. The primary outcome was a composite of 90-day postoperative all-cause mortality and emergency department visits. Secondary outcomes were postoperative delirium, prolonged postoperative stay (≥75th percentile), and prolonged hospital stay (≥21 days). An 80% versus 20% split of the data from the Seoul National University Bundang Hospital (SNUBH) and Seoul National University Hospital (SNUH) common data model was used for model training and testing versus external validation. Model performance was evaluated using the area under the receiver operating characteristic curve (AUC) with a 95% CI. RESULTS Data from 27,197 (SNUBH) and 32,857 (SNUH) patients were analyzed. Compared to the random forest, Adaboost, and decision tree models, the least absolute shrinkage and selection operator logistic regression model showed good internal discriminative accuracy (internal AUC 0.723, 95% CI 0.701-0.744) and transportability (external AUC 0.703, 95% CI 0.692-0.714) for the primary outcome. The model also possessed good internal and external AUCs for postoperative delirium (internal AUC 0.754, 95% CI 0.713-0.794; external AUC 0.750, 95% CI 0.727-0.772), prolonged postoperative stay (internal AUC 0.813, 95% CI 0.800-0.825; external AUC 0.747, 95% CI 0.741-0.753), and prolonged hospital stay (internal AUC 0.770, 95% CI 0.749-0.792; external AUC 0.707, 95% CI 0.696-0.718). Compared with age or the Charlson comorbidity index, the model showed better prediction performance. CONCLUSIONS The derived model shall assist clinicians and patients in understanding the individualized risks and benefits of surgery.

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
BACKGRUOUND Long term quality of life is becoming increasingly crucial as survival following partial pancreatectomy rises. The purpose of this study was to investigate the difference in glucose dysregulation after pancreaticoduodenectomy (PD) or distal pancreatectomy (DP). METHODS In this prospective observational study from 2015 to 2018, 224 patients who underwent partial pancreatectomy were selected: 152 (67.9%) received PD and 72 (32.1%) received DP. Comprehensive assessment for glucose regulation, including a 75 g oral glucose tolerance test was conducted preoperatively, and 1, 12, and 52 weeks after surgery. Patients were further monitored up to 3 years to investigate development of new-onset diabetes mellitus (NODM) in patients without diabetes mellitus (DM) at baseline or worsening of glucose regulation (≥1% increase in glycosylated hemoglobin [HbA1c]) in those with preexisting DM. RESULTS The disposition index, an integrated measure of β-cell function, decreased 1 week after surgery in both groups, but it increased more than baseline level in the PD group while its decreased level was maintained in the DP group, resulting in a between-group difference at the 1-year examination (P<0.001). During follow-up, the DP group showed higher incidence of NODM and worsening of glucose regulation than the PD group with hazard ratio (HR) 4.29 (95% confidence interval [CI], 1.49 to 12.3) and HR 2.15 (95% CI, 1.09 to 4.24), respectively, in the multivariate analysis including dynamic glycemic excursion profile. In the DP procedure, distal DP and spleen preservation were associated with better glucose regulation. DP had a stronger association with glucose dysregulation than PD. CONCLUSION Proactive surveillance of glucose dysregulation is advised, particularly for patients who receive DP.

Abstract
Pancreatic adenocarcinoma (PDAC) is one of the most common and lethal human cancers worldwide. Surgery followed by adjuvant chemotherapy offers the best chance of a long-term survival for patients with PDAC, although only approximately 20% of the patients have resectable tumors when diagnosed. Neoadjuvant chemotherapy (NACT) is recommended for borderline resectable pancreatic cancer. Several studies have investigated the role of NACT in treating resectable tumors based on the recent advances in PDAC biology, as NACT provides the potential benefit of selecting patients with favorable tumor biology and controls potential micro-metastases in high-risk patients with resectable PDAC. In such challenging cases, new potential tools, such as ct-DNA and molecular targeted therapy, are emerging as novel therapeutic options that may improve old paradigms. This review aims to summarize the current evidence regarding the role of NACT in treating non-metastatic pancreatic cancer while focusing on future perspectives in light of recent evidence.

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
PURPOSE We aimed to assess the role of adjuvant FOLFIRINOX, in comparison with other adjuvant therapy, in patients who received neoadjuvant FOLFIRINOX and surgery for borderline resectable or locally advanced pancreatic cancer (BRPC or LAPC). METHODS Our target population was patients with BRPC or LAPC, who received adjuvant therapy following neoadjuvant FOLFIRINOX and surgery between June 2013 and October 2020. Multivariable Cox proportional-hazard model was used to identify factors associated with overall survival (OS) and recurrence free survival (RFS). RESULTS Among 244 patients with BRPC or LAPC who received neoadjuvant FOLFIRINOX, 79 patients underwent subsequent surgery. Among them, 58 who received adjuvant therapy [median age, 63 years; 33 females (56.9%)] were included. Thirty patients received adjuvant modified FOLFIRINOX (mFOLFIRINOX), while 28 received adjuvant therapy other than FOLFIRINOX. In multivariable analysis, mFOLFIRINOX and post-treatment carbohydrate antigen 19-9 (CA 19-9) were significantly associated with OS and RFS. According to mFOLFIRINOX vs. other adjuvant therapy, median OS was not reached at 37.5 months of follow-up vs. 29.7 months (P = .012); and median RFS was 30.5 vs. 11.0 months (P = .028). According to post-treatment CA 19-9 (< 37 vs. ≥ 37 U/mL), median OS was 46.0 vs. 25.5 months (P = .022); and median RFS was 25.9 vs. 7.6 months (P = .012). CONCLUSION Continued adjuvant mFOLFIRINOX and post-treatment CA 19-9 level were associated with survival in patients with BRPC or LAPC who received neoadjuvant FOLFIRINOX and surgery. Continued adjuvant mFOLFIRINOX after neoadjuvant FOLFIRINOX could be considered for patients with good performance.

Abstract
Background and Objective Guidelines are required because of the wide variability in care provided to patients with similar characteristics and similar medical conditions. Quality indicators were developed many years ago to assess the quality of care provided by hospitals. Since then, it has become evident that a composite set of factors can better characterize the patient's quality of care. The objectives of this review were to analyze the textbook outcomes (TO) applied in surgery, focusing on laparoscopic hepatectomy. Methods Data pertaining to quality indicators used in hospitals and their surgical applications were retrieved from medical literature by searching PubMed and Google Scholar for articles published between 1912 and 2022. Search terms included quality indicators, outcome indicators, TOs, TOs after surgery, TOs after hepatectomy, and clinical indicators. Key Content and Findings Since their inception, TO have been applied to various procedures and their impacts on patients have been assessed. TO and their implications have been studied for a variety of surgical procedures and were recently extended to laparoscopic hepatectomy. TO of laparoscopic left lateral sectionectomy and right hemihepatectomy were recently assessed, and benchmark values have been defined. TO are useful tools for assessing hospital performance and for optimizing the outcomes of patients undergoing laparoscopic hepatectomy. Conclusions At present, TO only consider surgeon-related factors. However, it is important to include the patient's perspective when defining TO. Although TO were recently applied to laparoscopic hepatectomy, there is still a need to further evaluate their application in this setting. Achieving TO was shown to have a positive impact on long-term outcomes and this needs to be studied for different liver resection procedures.

Abstract
BACKGROUND This study aimed to validate and compare the performance of the original fistula risk scores (o-FRS), alternative (a-FRS), and updated alternative FRS (ua-FRS) after open pancreatoduodenectomy (OPD) and laparoscopic pancreatoduodenectomy (LPD) in an Asian patient cohort. METHODS Data of 597 consecutive patients who underwent PD (305 OPD, 274 LPD) were collected from two tertiary centers. Model performance was assessed using the area under the receiver operating curve (AUC). RESULTS The overall AUC values of o-FRS, a-FRS, and ua-FRS were 0.67, 0.69, and 0.68, respectively, which were lower than those of the Western validation. Three FRS systems had similar AUC values in the overall and OPD groups, whereas ua-FRS had a higher AUC than o-FRS in the LPD group. The accuracy of ua-FRS (47.2%) was higher than that of o-FRS (39.0%) and a-FRS (19.5%) overall, but low specificity and low positive predictive value were observed regardless of the operative type across the three FRS systems. In the multivariate analysis, pathology, estimated blood loss, and body mass index were not independent risk factors for CR-POPF in the OPD and LPD groups. CONCLUSIONS Current FRS systems have some limitations, including a relatively lower performance in an Asian cohort, low positive predictive values, and inclusion of insignificant risk factors.

Abstract
BACKGROUND The current definition for postoperative pancreatic fistula (POPF) is based on the drain fluid amylase (DFA), and drains must be positioned adequately. We investigated the impact of DFA level, drain position and fluid collection after distal pancreatectomy (DP). METHODS We performed a retrospective study of 516 patients who underwent DP between June 2004 and December 2018. Patients were excluded if DP was not main procedure, DFA was not measured, postoperative computed tomography (CT) was not performed, or drains were removed before CT. Demographic and perioperative data were analyzed in 422 eligible patients. RESULTS Of 422 patients, 49(11.6%) had clinically relevant (CR)-POPF and 102(24.2%) had a malpositioned drain. There was no difference in CR-POPF rate between the high and low DFA groups (12.6% vs 10.7%, P = 0.649). Drain malposition was more frequently associated with symptomatic fluid collection and CR-POPF than well-positioned drains. Male sex, high body mass index, transfusion, and drain malposition were CR-POPF risk factors. In subgroup analysis, drain malposition was also an independent risk factor for CR-POPF in the low DFA group. CONCLUSIONS After DP, the incidence of CR-POPF in the high and low DFA groups was similar and drain malposition increased the risk of CR-POPF. Thus, the ISGPS definition of POPF based on DFA levels is limited in DP, and DFA levels should be interpreted together with the drain position.

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
BACKGROUND The International Consensus Criteria (ICC) (2017) redefined patients with borderline resectable pancreatic ductal adenocarcinoma (BR-PDAC) according to anatomical, biological, and conditional aspects. However, these new criteria have not been validated comprehensively. The aim of this retrospective cohort study was to validate the anatomical and biological definitions of BR-PDAC for oncological outcomes in patients with resectable (R) and BR-PDAC undergoing upfront surgery. METHODS A total of 404 patients who underwent upfront surgery for R- and BR-PDAC from 2004 to 2020 were included. The patients were classified according to the ICC as follows: resectable (R) (n = 259), anatomical borderline (BR-A) (n = 43), biological borderline (BR-B) (n = 81), and anatomical and biologic borderline (BR-AB) (n = 21). RESULTS Compared with the R and BR-B groups, the BR-A and BR-AB groups had higher postoperative complication rates (16.5% and 27.2% vs 32.5% and 33.4%; P < 0.001) and significantly lower R0 resection rates (85.7% and 80.2% vs 65.1% and 61.9%; P = 0.003). In contrast, compared with the R and BR-A groups, the BR-B (32.1%) and BR-AB (57.1%) groups had higher early recurrence rates (within postoperative 6 months) (16.5% and 25.6% vs 32.1% and 57.1%; P < 0.001) and significantly lower 3-year recurrence-free survival rates (36.1% and 20.7% vs 12.1% and 7.8%; P < 0.001). CONCLUSION Anatomically defined BR-PDAC was associated with a higher risk of margin-positive resection and postoperative complication rates, while biologically defined BR-PDAC was associated with higher early recurrence rates and lower survival rates. Thus, the anatomical and biological definitions are useful in predicting the prognosis and determining the usefulness of neoadjuvant therapy.

Abstract
Background and Objectives: A difficulty scoring system was previously developed to assess the difficulty of laparoscopic liver resection (LLR) for liver tumors; however, we need another system for hepatolithiasis. Therefore, we developed a novel difficulty scoring system (nDSS) and validated its use for predicting postoperative outcomes. Materials and Methods: This was a retrospective study. We used clinical data of 123 patients who underwent LLR for hepatolithiasis between 2003 and 2021. We analyzed the data to determine which indices were associated with operation time or estimated blood loss (EBL) to measure the surgical difficulty. We validated the nDSS in terms of its ability to predict postoperative outcomes, namely red blood cell (RBC) transfusion, postoperative hospital stay (POHS), and major complications defined as grade ≥IIIa according to the Clavien−Dindo classification (CDC). Results: The nDSS included five significant indices (range: 5−17; median: 8). The RBC transfusion rate (p < 0.001), POHS (p = 0.002), and major complication rate (p = 0.002) increased with increasing nDSS score. We compared the two groups of patients divided by the median nDSS (low: 5−7; high: 8−17). The operation time (210.7 vs. 240.7 min; p < 0.001), EBL (281.9 vs. 702.6 mL; p < 0.001), RBC transfusion rate (5.3% vs. 37.9%; p < 0.001), POHS (8.0 vs. 13.3 days; p = 0.001), and major complication rate (8.8% vs. 25.8%; p = 0.014) were greater in the high group. Conclusions: The nDSS can predict the surgical difficulty and outcomes of LLR for hepatolithiasis and may help select candidates for the procedure and surgical approach.

Abstract
PURPOSE Delayed hemorrhage (DH) is a rare and yet well-known fatal complication associated with postoperative pancreatic fistula (POPF) in pancreatoduodenectomy (PD). The study aimed to investigate whether arterial reinforcement (AR) using polyglycolic acid sheets (PAS) followed by fibrin sealant (FS) to the hepatic artery could prevent DH in the setting of POPF after PD. METHODS A total of 345 patients underwent PD for periampullary tumors from March 2011 to March 2022. From March 2011 to March 2018, 225 patients underwent PD, and AR was not performed (non-AR group). From April 2018 to March 2022, 120 patients underwent PD, and AR was performed (AR group). AR was achieved by wrapping the proper hepatic artery all the way down to the celiac artery with PAS followed by coating with FS. Demographic profile and various outcomes including DH of these two groups were compared and analyzed retrospectively. RESULTS In non-AR group, 48 (21.3%) and 12 (5.3%) patients had grade B and C POPF, respectively. In AR group, 26 (21.7%) and four (3.3%) patients had grade B and C POPF, respectively. The incidence of POPF was not statistically significant (p = .702) between the groups. Among the patients with grade B or C POPF, DH occurred in 14 (23.3%) patients in non-AR group and only one patient in AR group (p = .016). Of the 15 patients with DH, four (26.7%) patients died. CONCLUSION AR using PAS and FS is effective in preventing DH in the setting of POPF.

Abstract
BACKGROUND Jejunal varix is a concerning late complication after pancreatoduodenectomy (PD) due to the risk of recurrent and intractable bleeding. Our aim was to investigate the incidence, risk factors, and outcomes of jejunal varix after PD. METHODS A total of 709 patients who underwent PD between 2007 and 2017 were included. Preoperative and postoperative CT images were reviewed to evaluate the development of portal vein (PV) stenosis (≥50%) and jejunal varices. RESULTS Jejunal varix developed in 83 (11.7%) patients at a median of 12 months after PD. Eighteen (21.7%) patients experienced variceal bleeding. PV stenosis (P < 0.001; odds ratio [OR] 33.2, 95% confidence interval [CI] 15.6-66.7) and PV/superior mesenteric vein resection (P = 0.028; OR 2.3, 95% CI 1.1-4.7) were independent risk factors for jejunal varix. Of the nine patients who underwent stent placement for PV stenosis before the formation of jejunal varices, none experienced variceal bleeding. By contrast, 18 (27.3%) of the 135 patients without PV stent placement experienced at least one episode of variceal bleeding. CONCLUSIONS The incidence of jejunal varix was substantial after PD. PV stenosis was a strong risk factor for jejunal varix. Early PV stent placement and maintaining stent patency could reduce the risk of variceal bleeding in patients with PV stenosis.

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
OBJECTIVE To evaluate the long-term outcomes of covered stent placement in patients with gastroduodenal artery (GDA) stump hemorrhage after pancreaticoduodenectomy (PD) and to identify risk factors of stent failure. METHODS AND MATERIALS Covered stent was placed in total of 21 patients for GDA stump hemorrhage after PD from September 2012 to March 2021. Technical and clinical success, complications, and stent patency were retrospectively evaluated. Nine relevant variables were analyzed to determine risk factors for stent failure. RESULTS In 20 of 21 patients (95.2%), the GDA stump was completely excluded with covered stent placement. Immediate hemostasis was achieved in the 20 patients and rebleeding from jejunal artery occurred in one patient which was successfully embolized one day after the stent placement. There was no procedure-related complication or early mortality (<30 days). During follow-up period (median 655.5 days), stent thrombosis was found on CT in 10 patients (50.0%, 10/20) without any laboratory or CT abnormalities. One thrombosed stent migrated into the jejunum 20 months after placement. The six-month, one-year, and two-year stent patency were 81.9%, 52.9%, and 37.8%, respectively (median 620 days). The recurrence of primary malignancy was associated with stent failure (HR 5.70; 95% CI 1.18-27.76, p = 0.03). CONCLUSIONS Covered stent placement is an effective and safe management of postoperative GDA stump hemorrhage. Stent failure occurred frequently (50%) but did not cause liver ischemia. Stent failure was associated with recurrence of primary malignancy. ADVANCES IN KNOWLEDGE 1. Covered stent placement is an effective and safe management of postoperative GDA stump hemorrhage.2. Stent failure occurred frequently (50%) but did not cause liver ischemia.3. Stent failure was associated with recurrence of primary malignancy.

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
BACKGROUND To investigate whether the administration of nafamostat mesilate (NM) reduces the risk of posthepatectomy liver failure (PHLF) in patients undergoing hepatectomy for hepatocellular carcinoma (HCC). METHODS We retrospectively reviewed the 1114 patients who underwent hepatectomy for HCC between 2004 and 2020. NM was selectively administered to patients undergoing major hepatectomy with an estimated blood loss of >500 mL. NM group was administered via intravenous of 20 mg of NM from immediately after surgery until postoperative day 4. We performed 1:1 propensity score matching and included 56 patients in each group. PHLF was defined according to the International Study Group of Liver Surgery (ISGLS). RESULTS The incidence of PHLF was lower in the NM group than control group (P = 0.018). The mean peak total bilirubin (P = 0.006), aspartate transaminase (P = 0.018), and alanine aminotransferase (P = 0.018) levels postoperatively were significantly lower in the NM group. The mean hospital stays (P = 0.012) and major complication rate (P = 0.023) were also significantly lower in the NM group. CONCLUSION Prophylactic administration of NM reduced the risks of complication and decreased the frequency of PHLF after hepatectomy. A further prospective study is needed to verify our findings.

Abstract
Gallbladder carcinoma (GBC) is a rare malignancy, with an estimated 5-year survival rate of less than 5% in the case of advanced disease. Surgery is the only radical treatment for early stages, but its application and effectiveness depend on the depth of tumoral invasion. The extent of resection is usually determined according to the T-stage. Therefore, an early and correct preoperative assessment is important for the prognosis, as well as for the selection of the most appropriate surgical procedure, to avoid unnecessary morbid surgeries and to reach the best outcomes. Several modalities can be used to investigate the depth of invasion, from ultrasounds to CT scans and MRI, but an ideal method still does not exist. Thus, different protocols are proposed according to different recommendations and institutions. In this scenario, the indications for laparoscopic and robotic surgery are still debated, as well as the role of new technologies such as next-generation sequencing and liquid biopsies. The aim of this article is to summarize the state of the art current modalities and future perspectives for assessing the depth of invasion in GBC and to clarify their role in perioperative management accordingly.

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
BACKGROUND The safety of laparoscopic liver resection (LLR) in elderly patients is a matter of concern because the reduced physiologic reserve increases the risk of postoperative complications. However, there are few score systems for predicting complications after LLR in elderly patients. The aim of this study is to propose a new simplified scoring system based on the Geriatric Nutritional Risk Index (GNRI) to predict major complications after LLR in elderly patients with hepatocellular carcinoma (HCC). METHODS We retrospectively reviewed 257 consecutive patients aged ≥ 65 years who underwent LLR for HCC between 2004 and 2019. The GNRI formula was 1.489 × serum albumin (g/L) + 41.7 × present weight/ideal weight (kg). A scoring system to predict the risk of major complications was developed by assigning points to each risk factor equal to its regression coefficient determined in the multivariable analysis. Major complications were defined as complications of Clavien-Dindo grade III or higher. RESULTS Of the 257 patients, 219 patients were finally included in this study. Major complications occurred after LLR in 24 patients (10.9%). Multivariable analysis showed that the GNRI (hazard ratio [HR] 3.396, 95% confidence interval [CI] 1.242-9.288, P = 0.017), Child-Turcotte-Pugh score (HR 2.191, 95% CI 1.400-8.999, P = 0.036), major liver resection (HR 2.683, 95% CI 1.082-7.328, P = 0.050), and intraoperative transfusion (HR 1.802, 95% CI 1.428-7.591, P = 0.022) were independent predictors of major postoperative complications. These variables were assigned points based on their HRs, and the resulting 10-point model showed good discrimination (area under the curve 0.756, 95% CI 0.649-0.836, P = 0.001). CONCLUSION The scoring system outperformed the GNRI for predicting major complications after LLR in elderly patients with HCC.

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
BACKGROUND The quality of surgical procedures are assessed by textbook outcomes (TO). LLR is considered a standard treatment for HCC in the anterolateral segments of the liver. The main objective of this study was to evaluate the factors affecting achievement of TO for laparoscopic liver resection (LLR) and its impact on survival. METHODS We conducted a retrospective cohort study of patients who underwent LLR for lesions located in the anterolateral segments (n=309). Patients were divided into TO and non-TO group. RESULTS A TO was achieved in 55.0% of patients (n=170). In multivariable analysis, Model for End-stage Liver Disease (MELD) score >10 (odds ratio[OR] 3.076; 95% confidence interval[CI] 1.134-8.342), absence of diabetes mellitus (OR 2.325; 95% CI 1.227-4.407) and thrombocytopenia (OR 2.115; 95% CI 1.134-8.342) were independently associated with not achieving TO. The 5-year overall (82.9% vs. 72.8%, P=0.017) and recurrence-free (48.8% vs. 35.4%; P=0.036) survival rates were significantly greater in the TO group than in the non-TO group. CONCLUSION The MELD score, thrombocytopenia, and hypoalbuminemia were independent risk factors influencing the achievement of TO. TO influences the short- and long-term outcomes after LLR for HCC.

Abstract
OBJECTIVE CT plays a central role in determining the resectability of pancreatic cancer, which directs the use of neoadjuvant therapy. This study aimed to assess the diagnostic accuracy of CT in predicting circumferential resection margin (CRM) involvement in patients with resectable or borderline resectable pancreatic head cancer. MATERIALS AND METHODS Seventy-seven patients who were scheduled for upfront surgery for resectable or borderline resectable pancreatic head cancer were prospectively enrolled, and 75 patients (38 male and 37 female; mean age ± standard deviation, 68 ± 11 years) were finally analyzed. The CRM status was evaluated separately for the superior mesenteric artery (SMA) and posterior and superior mesenteric vein/portal vein (SMV/PV) margins. Three independent radiologists reviewed the preoperative CT images and evaluated the resection margin status. The reference standard for CRM status was pathologic examination of pancreaticoduodenectomy specimens in an axial plane perpendicular to the axis of the second portion of the duodenum. The diagnostic accuracy of CT was assessed for overall CRM involvement, defined as involvement of the SMA or posterior margins (per-patient analysis), and involvement of each of the three resection margins (per-margin analysis). The data were pooled using a crossed random effects model. RESULTS Forty patients had pathologically confirmed overall CRM involvement in pancreatic cancer, while CRM involvement was not seen in 35 patients. For overall CRM involvement, the pooled sensitivity and specificity were 15% (95% confidence interval: 7%-49%) and 99% (96%-100%), respectively. For each of the resection margins, the pooled sensitivity and specificity were 14% (9%-54%) and 99% (38%-100%) for the SMA margin, 12% (8%-46%) and 99% (97%-100%) for the posterior margin; and 37% (29%-53%) and 96% (31%-100%) for the SMV/PV margin, respectively. CONCLUSION CT showed very high specificity but low sensitivity in predicting pathological CRM involvement in pancreatic cancer.

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.

We aimed to elucidate the evolutionary trajectories of gallbladder adenocarcinoma (GBAC) using multi-regional and longitudinal tumor samples. Using whole-exome sequencing data, we constructed phylogenetic trees in each patient and analyzed mutational signatures. A total of 11 patients including 2 rapid autopsy cases were enrolled. The most frequently altered gene in primary tumors was ERBB2 and TP53 (54.5%), followed by FBXW7 (27.3%). Most mutations in frequently altered genes in primary tumors were detectable in concurrent precancerous lesions (biliary intraepithelial neoplasia [BilIN]), but a substantial proportion was subclonal. Subclonal diversity was common in BilIN (n=4). However, among subclones in BilIN, a certain subclone commonly shrank in concurrent primary tumors. In addition, selected subclones underwent linear and branching evolution, maintaining subclonal diversity. Combined analysis with metastatic tumors (n=11) identified branching evolution in nine patients (81.8%). Of these, eight patients (88.9%) had a total of 11 subclones expanded at least sevenfold during metastasis. These subclones harbored putative metastasis-driving mutations in cancer-related genes such as SMAD4, ROBO1, and DICER1. In mutational signature analysis, six mutational signatures were identified: 1, 3, 7, 13, 22, and 24 (cosine similarity >0.9). Signatures 1 (age) and 13 (APOBEC) decreased during metastasis while signatures 22 (aristolochic acid) and 24 (aflatoxin) were relatively highlighted. Subclonal diversity arose early in precancerous lesions and clonal selection was a common event during malignant transformation in GBAC. However, selected cancer clones continued to evolve and thus maintained subclonal diversity in metastatic tumors.

Abstract
PURPOSE The impact of conversion on perioperative and long-term oncologic outcomes is controversial. Thus, we compared these outcomes between laparoscopic (Lap), unplanned conversion (Conversion), and planned open (Open) liver resection for hepatocellular carcinoma (HCC) located in anterolateral (AL) liver segments and aimed to identify risk factors for unplanned conversion. METHODS We retrospectively studied 374 patients (Lap, 299; Open, 62; Conversion, 13) who underwent liver resection for HCC located in AL segments between 2004 and 2018. RESULTS Compared to the Lap group, the Conversion group showed greater values for operation time (p < 0.001), blood loss (p = 0.021), transfusion rate (p = 0.009), postoperative complication rate (p = 0.008), and hospital stay (p = 0.040), with a lower R0 resection rate (p < 0.001) and disease-free survival (p = 0.001). Compared with the Open group, the Conversion group had a longer operation time (p = 0.012) and greater blood loss (p = 0.024). Risk factors for unplanned conversion were large tumor size (odds ratio [OR], 1.35; 95% confidence interval [CI], 1.05-1.74; p = 0.020), multiple tumors (OR, 5.95; 95% CI, 1.45-24.39; p = 0.013), and other organ invasion (OR, 15.32; 95% CI, 1.80-130.59; p = 0.013). CONCLUSION In conclusion, patients who experienced unplanned conversion during LLR for HCC located in AL segments showed poor perioperative and long-term outcomes compared to those who underwent planned laparoscopic and open liver resection. Therefore, open liver resection should be considered in patients with risk factors for unplanned conversion.

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
Although there is no established desensitization protocol for liver transplantation (LT), desensitization usually entails treatment with rituximab, plasmapheresis, splenectomy, and intravenous immunoglobulin (IVIG) infusion together with a local graft. The desensitization protocol is usually initiated 2 to 3 weeks before transplantation. Therefore, patients with acute liver failure warranting urgent LT are usually ineligible for ABO-incompatible (ABOi) LT. For these reasons, several attempts have been made to abridge the desensitization protocol and extend the indication for ABOi living donor LT (LDLT). Here we report a 40-year-old female diagnosed with chronic hepatitis B and acute-on-chronic liver failure (model for end-stage liver disease score, 31). In the absence of a suitable compatible liver donor, emergency ABOi LT was planned using a modified desensitization protocol. The preoperative isoagglutinin (IA) titer was 1 : 1,024 and the preoperative T- and B-cell cross-matches were positive. The patient received a single dose of rituximab (375 mg/m2) and IVIG (0.8 g/kg) was administered from the anhepatic phase until three days after transplantation. Although the patient developed acute cellular rejection in the early stages after LT, she has maintained a stable graft function, even after 5 years. In summary, a modified desensitization protocol consisting of rituximab and IVIG is a feasible strategy for highly sensitized patients with elevated IA titers indicated for urgent LDLT.

Abstract
Although angiomyolipoma (AML) is commonly found in the kidney, its appearance in the liver is rare. The first hepatic AML was reported by Ishak in 1976. Since then, there have been various reports of AML. An AML is a tumour affecting adipocytes, muscle tissues, and blood vessels. Hepatic AML has been associated with tuberous sclerosis. Its spontaneous occurrence has also been noticed. It can have a varied presentation with some being asymptomatic, others presenting with a dull aching pain, while some with disastrous consequences due to rupture and torrential bleeding intra-abdominally. Herein, we present a case of a 47-year-old female with a large hepatic AML having an internal hemorrhage that caused changes in hepatic arteries. In our case, magnetic resonance imaging was unable to establish a diagnosis. Intraoperatively, AML caused dilatation and engorgement of vessels around the porta. Immediately post resection, vessel dilatation and engorgement were reduced on table. Another notable feature was that these changes caused no intra-operative or post-operative hemodynamic changes. We report a case of a huge hepatic AML with internal hemorrhage associated with perihepatic vascular changes having a successful surgical treatment.

Abstract
INTRODUCTION The impact of acute inflammation on cancer progression is still not well elucidated. Pancreatic head cancer is occasionally associated with acute cholangitis. C-reactive protein (CRP) is a biomarker that indicates presence of acute inflammation. METHODS We reviewed the patients' data with pancreatic ductal adenocarcinoma (PDAC) who underwent pancreaticoduodenectomy between 2004 and 2018. RESULTS Two hundred ninety-one patients were included. Median preoperative CRP was 0.45 mg/dL (0-18.9). Median follow-up duration was 22 months (4-152). The 1-, 3-, and 5-year overall survival (OS) rates were 76.4%, 32.2%, and 22.9%, respectively. Recurrence occurred in 168 cases (57.7%). The 1-, 3-, and 5-year disease-free survival (DFS) rates were 53.9%, 27.1%, and 21.9%, respectively. The median OS was higher in normal CRP patients (27 months) than those with elevated CRP (18 months) (log-rank 0.038). The median DFS was higher in normal CRP patients (17 months) than those with elevated CRP (9 months) (log-rank < 0.001). Predictive factors for OS included BMI, CRP, adjuvant therapy, positive lymph nodes, and microvascular invasion. Predictive factors for DFS included CRP, positive lymph nodes, and microvascular invasion. CONCLUSION Preoperative CRP was an independent poor prognostic factor for OS and DFS of patients with resected PDAC.
