Critical social media literacy-the ability to critically evaluate and interpret racist social media content (critical consumption) and to produce and disseminate antiracist social media content (critical prosumption)-may help counter the negative psychological consequences of online racism, including internalized racism. We examined whether critical social media literacy (critical consumption and prosumption) buffered the association between online racism and internalized racism. We conducted latent moderated structural equation modeling to analyze online convenience data from 338 racially minoritized emerging adults ( M age = 23.28; Asian, n = 96; Black, n = 108; Latine, n = 118). Greater exposure to online racism was associated with significantly higher levels of internalized racism; critical consumption weakened this association, while critical prosumption did not. Results suggested that critical social media literacy, particularly consumption-the intellectual basis and analytical skills to apprehend racist digital content-can be effective in mitigating the internalized racism linked to online racism among racially minoritized emerging adults. Implications include translating these findings into antiracist interventions to counter online racism and its deleterious behavioral health consequences.

This study systematically reviews the effects of muscle strength exercises on muscle mass and strength in stroke patients by analyzing randomized controlled trials. Ten studies, involving a total of 378 stroke patients, were included in the meta-analysis. The standardized mean difference (SMD) and confidence intervals (CIs) were calculated using a random effects model. The results indicated that strength exercises had a medium effect on increasing muscle strength in stroke patients (SMD, 0.6; 95% CI, 0.47-0.72; I 2 =51%; P <0.05). Specifically, strength exercises were found to be particularly effective in chronic stroke patients, showing a medium effect on muscle strength (SMD, 0.68; 95% CI, 0.55-0.81; I 2 =45%; P <0.05). The study also compared the effects based on repetition maximum (RM) settings, revealing that strength increased significantly regardless of whether RM was used, with studies showing medium effects (with RM: SMD, 0.52; 95% CI, 0.4-0.64; I 2 =0%; P <0.05; without RM: SMD, 0.65; 95% CI, 0.4-0.91; I 2 =72%; P <0.05). The study concludes that strength exercises are beneficial for improving muscle strength in chronic stroke patients, but the use of RM to set exercise intensity is not strictly necessary., Competing Interests: CONFLICT OF INTEREST No potential conflict of interest relevant to this article was reported., (Copyright © 2024 Korean Society of Exercise Rehabilitation.)

The global research and pharmaceutical community rapidly mobilized to develop treatments for coronavirus disease 2019 (COVID-19). Existing treatments have been repurposed and new drugs have emerged. Here we summarize mechanisms and clinical trials of COVID-19 therapeutics approved or in development. Two reviewers, working independently, reviewed published data for approved COVID-19 vaccines and drugs, as well as developmental pipelines, using databases from the following organizations: United States Food and Drug Administration (US-FDA), European Medicines Agency (EMA), Japanese Pharmaceutical and Medical Devices Agency (PMDA), and ClinicalTrials.gov. In all, 387 drugs were found for initial review. After removing unrelated trials and drugs, 66 drugs were selected, including 17 approved drugs and 49 drugs under development. These drugs were classified into six categories: 1) drugs targeting the viral life cycle 2) Anti-severe acute respiratory syndrome coronavirus 2 Monoclonal Antibodies, 3) immunomodulators, 4) anti-coagulants, 5) COVID-19-induced neuropathy drugs, and 6) other therapeutics. Among the 49 drugs under development are the following: 6 drugs targeting the viral life cycle, 12 immunosuppression drugs, 2 immunostimulants, 2 HIF-PHD targeting drugs, 3 GM-CSF targeting drugs, 5 anti-coagulants, 2 COVID-19-induced neuropathy drugs, and 17 others. This review provides insight into mechanisms of action, properties, and indications for COVID-19 medications., Competing Interests: The authors have no conflicts of interest to disclose., (© 2024 The Korean Academy of Medical Sciences.)

Purpose: This study aimed to determine the impact of an intervention using voice recording of family members on pain, anxiety, and agitation in patients undergoing weaning from mechanical ventilation., Methods: A randomized control pre-post experimental design was implemented to 53 participants, with 27 and 26 participants in the experimental and control groups, respectively. A 70-second voice recording of a family member, repeated three times at 10-minute intervals was used as an intervention for the experimental group. Meanwhile, participants in the control group used headset for 30 minutes. Structured instruments were utilized to measure pain, anxiety, agitation, and the weaning process. Wilcoxon Signed Ranks test and the Mann-Whitney U test, or χ² test, were used for data analysis., Results: The experimental group exhibited significant decrease in pain (Z = -3.53, p < .001), anxiety (t = 5.45, p < .001), and agitation (Z = -2.99, p = .003) scores compared with those of the control group. However, there was no significant difference between groups in the weaning process' simplification (χ² = 0.63, p = .727)., Conclusion: Intervention using family members' voice recording effectively reduces pain, anxiety, and agitation in patients undergoing weaning from mechanical ventilation. This can be actively utilized to provide a more comfortable process for patients., Competing Interests: Song, Eun Kyeung has been the editorial board member of JKAN since 2024 but has no role in the review process.

Background: Over the last decade, extracorporeal membrane oxygenation (ECMO) use in critically ill children has increased and is associated with favorable outcomes. Our study aims to evaluate the current status of pediatric ECMO in Korea, with a specific focus on its volume and changes in survival rates based on diagnostic indications., Methods: This multicenter study retrospectively analyzed the indications and outcomes of pediatric ECMO over 10 years in patients at 14 hospitals in Korea from January 2012 to December 2021. Four diagnostic categories (neonatal respiratory, pediatric respiratory, post-cardiotomy, and cardiac-medical) and trends were compared between periods 1 (2012-2016) and 2 (2017-2021)., Results: Overall, 1065 ECMO runs were performed on 1032 patients, with the annual number of cases remaining unchanged over the 10 years. ECMO was most frequently used for post-cardiotomy (42.4%), cardiac-medical (31.8%), pediatric respiratory (17.5%), and neonatal respiratory (8.2%) cases. A 3.7% increase and 6.1% decrease in pediatric respiratory and post-cardiotomy cases, respectively, were noted between periods 1 and 2. Among the four groups, the cardiac-medical group had the highest survival rate (51.2%), followed by the pediatric respiratory (46.4%), post-cardiotomy (36.5%), and neonatal respiratory (29.4%) groups. A consistent improvement was noted in patient survival over the 10 years, with a significant increase between the two periods from 38.2% to 47.1% ( P = 0.004). Improvement in survival was evident in post-cardiotomy cases (30-45%, P = 0.002). Significant associations with mortality were observed in neonates, patients requiring dialysis, and those treated with extracorporeal cardiopulmonary resuscitation ( P < 0.001). In pediatric respiratory ECMO, immunocompromised patients also showed a significant correlation with mortality ( P < 0.001)., Conclusion: Pediatric ECMO demonstrated a steady increase in overall survival in Korea; however, further efforts are needed since the outcomes remain suboptimal compared with global outcomes., Competing Interests: The authors have no potential conflicts of interest to disclose., (© 2024 The Korean Academy of Medical Sciences.)

Introduction: The impact of pediatric intensivists on managing pediatric patients with diabetic ketoacidosis (DKA) remains unknown. This study aimed to evaluate the impact of pediatric intensivists on outcomes in pediatric intensive care units (PICUs)., Methods: This was a two-institution retrospective study of patients with DKA admitted to the PICU between 2012 and 2023. Pediatric patients (< 19 years of age) were included if they met the moderate to severe DKA criteria on PICU admission. The patients were subsequently divided into two groups based on the presence or absence of a pediatric intensivist. The primary outcome was the PICU length of stay (LOS). Secondary outcomes were adverse events during DKA treatment, hospital LOS, and mortality., Results: Fifty-two patients admitted to the PICU with a median age of 13.00 years (range, 0-18 years) were included; 32 (61.54%) were female. Patients managed by pediatric intensivists had significantly shorter PICU LOS (2.52 vs. 3.69 days, p < 0.05). Also, adverse events during DKA treatment were significantly decreased in the high-intensity group compared to the low-intensity group (12.50% vs. 50.00%, p < 0.05)., Conclusions: High-intensity ICU staffing was associated with shorter PICU LOS and lower adverse events in pediatric patients with DKA. Our results suggest that dedicated pediatric intensivists can improve outcomes of critically ill pediatric patients with DKA., (© 2023. The Author(s).)

Competing Interests: Disclosure All authors disclosed no financial relationships. Commentary ERCP in Billroth II anatomy can be endoscopically challenging. In the majority of cases, a standard duodenoscope is not able to be advanced to the ampulla, limiting available devices for cannulation and therapy because of the longer and narrower working channel of a pediatric colonoscope. In this case, the authors describe a patient with Billroth II anatomy with a surgical alteration in which a second anastomosis is created to allow for a “gastric access loop.” The small-bowel limb with the ampulla is anastomosed to the gastric antrum, leaving the ampulla only 10 to 12 cm from the gastric antrum and allowing conventional ERCP to be performed with a standard duodenoscope. Given the plethora of patients in whom biliary pathologic changes develop after Billroth II and Roux-en-Y surgery, standardizing this technique would dramatically simplify ERCP in altered anatomy.

Background: Percutaneous liver biopsy (P-bx) is the gold standard for diagnosing advanced fibrosis. Despite the proven technical feasibility of EUS-guided liver bx (EUS-bx) as a novel alternative way of liver biopsy, the clinical applicability remains to be determined., Aims: The primary aim of this study is to evaluate if EUS-bx, compared to P-bx, can effectively and safely obtain adequate specimen and accurately predict hepatic fibrosis., Methods: This is a single center, retrospective chart review among patients with liver diseases at a tertiary endoscopy center from February 2011 to March 2020. We assessed the EUS-bx versus P-bx outcomes by success rate, performance, and safety profile. The primary outcome was the association between EUS-bx clinical variables and the presence of histologic liver fibrosis stage ≥ 3. The secondary outcomes were the associations between EUS-bx and variables indicative of fibrosis., Results: Fifty-nine patients underwent EUS-bx; and 59, P-bx. All EUS-bx procedures were successfully completed. All 56/56 (100%) of EUS-bx vs. 50/52 (96.2%) P-bx were considered adequate samples. Tissue lengths were significantly longer in the EUS-bx cohort (p < 0.0001) with a trend towards a greater number of portal tracts. 46/56 (82.1%) cases of EUS-bx vs. 32/52 (61.5%) of P-bx had > 10 portal tracts; 21/56 (37.5%) cases of EUS-bx vs. 14/52 (26.9%) of P-bx had > 15 portal tracts. There were 6 (10.2%) EUS-bx vs. 1 (1.7%) P-bx related complication leading to a phone call (p = 0.061)., Conclusions: EUS-bx can safely performed and accurately predict liver fibrosis stage as the standard P-bx without being influenced by procedure-related factors., (© 2023.

Background: Monitoring mortality trends can help design ways to improve survival, but observation of national mortality trends in critically ill children is lacking for the Korean population., Methods: We analyzed the incidence and mortality trends of children younger than 18 years admitted to an intensive care unit (ICU) from 2012 to 2018 using the Korean National Health Insurance database. Neonates and neonatal ICU admissions were excluded. Multivariable logistic regression analyses were performed to estimate the odds ratio of in-hospital mortality according to admission year. Trends in incidence and in-hospital mortality of subgroups according to admission department, age, presence of intensivists, admissions to pediatric ICU, mechanical ventilation, and use of vasopressors were evaluated., Results: The overall mortality of critically ill children was 4.4%. There was a significant decrease in mortality from 5.5% in 2012 to 4.1% in 2018 ( P for trend < 0.001). The incidence of ICU admission in children remained around 8.5/10,000 population years ( P for trend = 0.069). In-hospital mortality decreased by 9.2% yearly in adjusted analysis ( P < 0.001). The presence of dedicated intensivists ( P for trend < 0.001, mortality decrease from 5.7% to 4.0%) and admission to pediatric ICU ( P for trend < 0.001, mortality decrease from 5.0% to 3.2%) were associated with significant decreasing trends in mortality., Conclusion: Mortality among critically ill children improved during the study period, and the improving trend was prominent in children with high treatment requirements. Varying mortality trends, according to ICU organizations, highlight that advances in medical knowledge should be supported structurally., Competing Interests: The authors have no potential conflicts of interests to disclose., (© 2023 The Korean Academy of Medical Sciences.)

Online racism is a digital social determinant to health inequity and an acute and widespread public health problem. To explore the heterogeneity of online racism exposure within and across race, we latent class modelled this construct among Asian ( n  = 310), Black ( n  = 306), and Latinx ( n  = 163) emerging adults in the United States and analysed key demographic and psychosocial health correlates. We observed Low and Mediated Exposure classes across all racial groups, whereas High Exposure classes appeared among Asian and Black people and the Systemic Exposure classes emerged uniquely in Asian and Latinx people. Generally, the High Exposure classes reported the greatest psychological distress and unjust views of society compared to all other classes. The Mediated and Systemic Exposure classes reported greater mental health costs than the Low Exposure classes. Asian women were more likely to be in the Mediated Exposure class compared to the Low Exposure class, whereas Black women were more likely to be in the Mediated Exposure class compared to both High and Low Exposure classes. About a third of each racial group belonged to the Low Exposure classes. Our findings highlight the multidimensionality of online racism exposure and identify hidden yet divergently risky subgroups. Research implications include examination of class membership chronicity and change over time, online exposure to intersecting oppressions, and additional antecedents and health consequences of diverse forms of online racism exposure.

Background: Revision of a failed laparoscopic fundoplication carries higher risk of complication and lower chance of success compared to the original surgery. Transoral incisionless fundoplication (TIF) may be an endoscopic alternative for select GERD patients without need of a moderate/large hiatal hernia repair. The aim of this study was to assess feasibility, efficacy, and safety of TIF 2.0 after failed laparoscopic Nissen or Toupet fundoplication (TIFFF)., Methods: This is a multicenter retrospective cohort study of patients who underwent TIFFF between September 2017 and December 2020 using TIF 2.0 technique (EsophyX Z/Z+) performed by gastroenterologists and surgeons. Patients were included if they had (1) recurrent GERD symptoms, (2) pathologic reflux based upon pH testing or Grade C/D esophagitis or Barrett's esophagus, and (3) hiatal hernia ≤ 2 cm. The primary outcome was improvement in GERD Health-Related Quality of Life (GERD-HRQL) post-TIFFF. The TIFFF cohort was also compared to a similar surgical re-operative cohort using propensity score matching., Results: Twenty patients underwent TIFFF (median 4.1 years after prior fundoplication) and mean GERD-HRQL score improved from 24.3 ± 22.9 to 14.75 ± 21.6 (p = 0.014); mean Reflux Severity Index (RSI) score improved from 14.1 ± 14.6 to 9.1 ± 8.0 (p = 0.046) with 8/10 (80%) of patients with normal RSI (< 13) post-TIF. Esophagitis healed in 78% of patients. PPI use decreased from 85 to 55% with 8/20 (45%) patients off of PPI. Importantly, mean acid exposure time decreased from 12% ± 17.8 to 0.8% ± 1.1 (p = 0.028) with 9/9 (100%) of patients with normalized pH post-TIF. There were no statistically significant differences in clinical efficacy outcomes between TIFFF and surgical revision, but TIFFF had significantly fewer late adverse events., Conclusion: Endoscopic rescue with TIF is a safe and efficacious alternative to redo laparoscopic surgery in symptomatic patients with appropriate anatomy and objective evidence of persistent or recurrent reflux., (© 2023.

Objective: We investigated whether gendered racism predicts depressive symptoms and alcohol use severity among Asian American men (AAM) through indirect relations via culture-specific family and external shame., Method: We analyzed convenience data from 409 AAM. Sample age ( M = 21.24), nativity, ethnicity, education, income, and self-reported social class were diverse and controlled for. We path modeled direct associations among gendered racism and depressive symptoms and alcohol use severity, and their indirect (mediated) associations through family and external shame., Results: About 21% and 25% of the sample met the clinical cutoffs for depressive symptoms and risky alcohol use, respectively. Gendered racism predicted depressive symptoms indirectly via external shame, and predicted alcohol use severity directly and indirectly via family shame. The hypothesized model fits the data better than an alternative model with shame factors as predictors., Conclusion: Gendered racism is an insidious psychiatric risk factor for AAM and appears to exacerbate family and external shame, which may subsequently and divergently increase depressive symptoms and alcohol use severity. Findings highlight the role of cultural factors within gendered racism-related stress processes among AAM. Future research should consider longitudinal designs and additional mediating and outcome variables to examine the behavioral health sequelae of gendered racism among AAM.

Background: The utility of combination rectal NSAID and topical epinephrine (EI) or rectal NSAID and normal saline (SI) sprayed on duodenal papilla in the prevention of post-ERCP pancreatitis (PEP) has been studied but results have been conflicting., Aims: To evaluate the benefit of using combination prophylaxis in preventing PEP., Methods: A literature search was performed using Scopus, PubMed/MEDLINE, and Cochrane databases in May 2021. Randomized controlled trials (RCTs) involving adults patients who underwent ERCP and received EI versus SI were eligible for inclusion. The pooled effect was expressed as odds ratio (OR) to assess the rate of PEP, severity of PEP, and specific adverse events. The results were pooled using Reviewer Manager 5.4 software., Results: Six RCTs involving 4016 patients were included in the final analysis. The EI group did not demonstrate any significant benefit over SI group in preventing PEP (OR = 1.00, 95% CI [0.68, 1.45], P = 0.98), irrespective of gender or the epinephrine concentration used. The tests for subgroup differences were not statistically significant with P-values of 0.66 and 0.28, respectively. The addition of topical epinephrine to rectal NSAID did not improve the rate of moderate to severe PEP (OR = 0.94, P = 0.86) or PEP in high-risk patients (OR = 1.14, 95%, P = 0.73). The rates of infection, including cholangitis and sepsis (OR = 0.63, P = 0.07), gastrointestinal bleeding (OR = 1.25, P = 0.56) and procedure-related death (OR = 0.71, P = 0.59) were similar between both groups., Conclusion: The addition of topical epinephrine did not demonstrate any benefit over rectal NSAID alone in preventing PEP or reducing other procedure-related adverse events., (© 2022.

Background Although the outcome of cardiopulmonary resuscitation (CPR) is still unsatisfactory, there are few studies about temporal trends of in-hospital CPR incidence and mortality. We aimed to evaluate nationwide trends of in-hospital CPR incidence and its associated risk factors and mortality in pediatric patients using a database of the Korean National Health Insurance between 2012 and 2018. Methods and Results We excluded neonates and neonatal intensive care unit admissions. Incidence of in-hospital pediatric CPR was 0.58 per 1000 admissions (3165 CPR/5 429 471 admissions), and the associated mortality was 50.4%. Change in CPR incidence according to year was not significant in an adjusted analysis ( P =0.234). However, CPR mortality increased significantly by 6.6% every year in an adjusted analysis ( P <0.001). Hospitals supporting pediatric critical care showed 37.7% lower odds of CPR incidence ( P <0.001) and 27.5% lower odds of mortality compared with other hospitals in the adjusted analysis ( P <0.001), and they did not show an increase in mortality ( P for trend=0.882). Conclusions Temporal trends of in-hospital CPR mortality worsened in Korea, and the trends differed according to subgroups. Study results highlight the need for ongoing evaluation of CPR trends and for further CPR outcome improvement among hospitalized children.

Importance: A growing body of literature has been developed with the goal of attempting to understand the experiences of female surgeons. While it has helped to address inequities and promote important programmatic improvements, work remains to be done., Objective: To explore how practicing male and female surgeons' experiences with gender compare across 5 qualitative/quantitative domains: career aspirations, gender-based discrimination, mentor-mentee relationships, perceived barriers, and recommendations for change., Design, Setting, and Participants: This national concurrent mixed-methods survey of Fellows of the American College of Surgeons (FACS) compared differences between male and female FACS. Differences between female FACS and female members of the Association of Women Surgeons (AWS) were also explored. A randomly selected 3:1 sample of US-based male and female FACS was surveyed between January and June 2020. Female AWS members were surveyed in May 2020., Exposure: Self-reported gender., Main Outcomes and Measures: Self-reported experiences with career aspirations (quantitative), gender-based discrimination (quantitative), mentor-mentee relationships (quantitative), perceived barriers (qualitative), and recommendations for change (qualitative)., Results: A total of 2860 male FACS (response rate: 38.1% [2860 of 7500]) and 1070 female FACS (response rate: 42.8% [1070 of 2500]) were included, in addition to 536 female AWS members. Demographic characteristics were similar between randomly selected male and female FACS, with the notable exception that female FACS were less likely to be married (720 [67.3%] vs 2561 [89.5%]; nonresponse-weighted P < .001) and have children (660 [61.7%] vs 2600 [90.9%]; P < .001). Compared with female FACS, female AWS members were more likely to be younger and hold additional graduate degrees (320 [59.7%] were married; 238 [44.4%] had children). FACS of both genders acknowledged positive and negative aspects of dealing with gender in a professional setting, including shared experiences of gender-based harassment, discrimination, and blame. Female FACS were less likely to have had gender-concordant mentors. They were more likely to emphasize the importance of gender when determining career aspirations and prioritizing future mentor-mentee relationships. Moving forward, female FACS emphasized the importance of avoiding competition among female surgeons. They encouraged male surgeons to acknowledge gender bias and admit their potential role. Male FACS encouraged male and female surgeons to treat everyone the same., Conclusions and Relevance: Experiences with gender are not limited to supportive female surgeons. The results of this study emphasize the importance of recognizing the voices of all stakeholders involved when striving to promote workforce diversity and the related need to develop quality improvement/surgical education initiatives that enhance inclusion through open, honest discourse.

The COVID-19 pandemic has incited widespread anti-Asian racism, which is linked to numerous behavioral health consequences including depressive symptoms. As racism-induced depressive symptoms are linked to coping-related alcohol use and because alcohol-related problems represent a significant public health concern in this population, we investigated whether COVID-19 racism predicted alcohol use severity through depressive symptoms and drinking to cope motives among Asian American emerging adults ( N = 139; M age = 23.04; 50% women, 50% men). We conducted a serial mediation wherein COVID-19 racism predicted alcohol use severity sequentially through depressive symptoms and drinking to cope motives. COVID-19 racism directly and significantly predicted alcohol use severity. The indirect effect via depressive symptoms and drinking to cope motives was also significant, suggesting that COVID-19 racism is likely a risk factor for alcohol-related problems. Results inform intervention science and highlight the need for policy and behavioral health services to curb COVID-19 racism., Competing Interests: The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© 2022 Society for the Study of Emerging Adulthood and SAGE Publishing.)

Background and Aims: Endoscopic ultrasound is a novel diagnostic approach to chronic liver diseases (CLDs), and EUS-guided porto-systemic pressure gradient measurement (EUS-PPG) is an important expansion with a well-developed technique. However, the clinical value and applicability of EUS-PPG measurement in predicting histologically advanced hepatic fibrosis remain unknown., Methods: This was a single-center retrospective study on patients with various CLDs undergoing EUS-PPG and EUS-guided liver biopsy (EUS-bx) to assess if EUS-PPG measurements correlate with histological fibrosis stage and various surrogate markers for severity of CLDs and its safety. Cases with EUS-PPG were identified at the University of California Irvine, a tertiary endoscopy center, between January 2014 and March 2020., Results: In 64 patients, the mean age was 57.5; 40 (62.5%), males; mean Child-Turcotte-Pugh (CTP) and Model for End-Stage Liver Disease (MELD) scores, 5.9 and 10.4, respectively. The procedure success rate was 100%. Twenty-nine (45.3%) had EUS-PPG ≥ 5 mmHg that was associated with clinical cirrhosis (p < 0.0001), clinical portal hypertension (p = 0.002), hepatic decompensation (p = 0.013), MELD-Na > 10 (p = 0.036), PLTs ≤ 120 × 10 9 /L (p = 0.001), INR ≥ 1.05 (p = 0.007), presence of EV, GV, or PHG (p < 0.0001), biopsy-proven fibrosis stage ≥ 3 (p = 0.002), APRI > 2 (p = 0.001), and FIB-4 > 3.25 (p = 0.001). Multivariable analysis confirmed that EUS-PPG ≥ 5 mmHg was significantly associated with liver biopsy-proven fibrosis stage ≥ 3 (LR 27.0, 95% CI = 1.653-360.597, p = 0.004), independent of C-cirrhosis, C-PHTN, thrombocytopenia, splenomegaly, and APRI score > 2, and FIB-4 score > 3.25. There were no serious complications related to EUS-PPG procedures., Conclusions: EUS-PPG measurements provide excellent correlation with histological hepatic fibrosis stage and various clinical, laboratory, endoscopic and imaging variables indicative of advanced liver disease without serious adverse events., (© 2022.

Aim: The 2018 life-sustaining treatment (LST) decision law is expected to improve end-of-life quality in Korea. This study evaluated the national effect of the LST decision law on the cardiopulmonary resuscitation (CPR) rate among pediatric patients who died during hospital admission., Methods: This retrospective cohort study was based on the Korean National Health Insurance database. Pediatric admissions within 12 months before or after implementation of the LST decision law were compared, allowing a 1-month transition period (February 2018). The changes in mortality, CPR, and documentation of LST decision were evaluated., Results: The CPR rate of patients who died in hospital decreased after establishment of the LST decision law (49.6 vs 43.4 %, P = 0.04), without change of in-hospital mortality between pre/post-LST decision law activation (0.83 vs 0.81 per 1000 admissions, P = 0.67). In addition, in-hospital CPR (0.73 vs 0.67 per 1000 admissions, P = 0.15) and survival to discharge after in-hospital CPR (43.6 vs 47.2 %, P = 0.27) were slightly improved, although there was no statistical significance. Patients with LST decision documentation were less frequently mechanically ventilated (69.8 % vs 80.4 %, P < 0.01) and used fewer inotropes (76.5 % vs 90.1 %, P < 0.01) and more frequent opioids (67.1 % vs 57.4 %, P = 0.04)., Conclusions: The legally guided process of LST decision can decrease the CPR rate of children who die in hospitals. This result highlights the possibility of improving end-of-life quality by reducing non-beneficial in-hospital CPR., Competing Interests: Conflicts of Interest Statement There is no conflict of interest for any author related to this paper., (Copyright © 2022 Elsevier B.V.

Preexisting donor-specific antibodies (DSA) to MHC antigens increase the risk of antibody-mediated rejection (AMR) in sensitized transplant recipients and reduces graft survival. Pretransplant desensitization with costimulation blockade and proteasome inhibition has facilitated transplantation in our preclinical nonhuman primate (NHP) model. However, long-term graft survival is limited by rebound of DSA after transplantation. In this study, we performed kidney transplants between highly sensitized, maximally MHC-mismatched NHPs ( n =14). At kidney transplantation, primates received T cell depletion with rhesus-specific anti-thymocyte globulin (rhATG; n =10) or monoclonal anti-CD4 and anti-CD8 antibodies ( n =4). Maintenance immunosuppression consisted of belatacept and tacrolimus ( n =5) or belatacept and rapamycin ( n =9) with steroids. Rebound of DSA post-kidney transplantation was significantly reduced compared with maintenance immunosuppression with tacrolimus, mycophenolate, and steroids. Protocol lymph node biopsy specimens showed a decrease in germinal center activity, with low frequencies of T follicular helper cells and class-switched B cells after kidney transplantation. Combined belatacept and rapamycin was superior in controlling viral reactivation, enabling weaning of ganciclovir prophylaxis. Tacrolimus was associated with increased morbidity that included cytomegalovirus and parvovirus viremia and post-transplant lymphoproliferative disorder. All primates in the tacrolimus/belatacept group failed discontinuation of antiviral therapy. Overall, belatacept-based immunosuppression increased AMR-free graft survival by controlling post-transplant humoral responses in highly sensitized NHP recipients and should be further investigated in a human clinical trial., Competing Interests: A.

Background and Aim: The portal pressure gradient (PPG) is a useful predictor of portal hypertension (PH) related complications. We previously showed the feasibility and safety of endoscopic ultrasound guided PPG measurement (EUS-PPG). Now EUS-guided liver biopsy (EUS-bx) has been shown to be a safe and effective alternative to percutaneous or Interventional Radiology-guided liver biopsy for the diagnosis of chronic liver disease (CLD). We aimed to evaluate the correlation between PPG and clinical markers of PH, and assess the feasibility and safety of concomitant, single session EUS-PPG and EUS-bx., Methods: This was a retrospective study of patients undergoing EUS-PPG for CLD at a single tertiary endoscopy center between February 2014 and March 2020. EUS-PPG was performed using a 25-gauge needle and compact manometer. Data analysis was performed with SAS version 9.4., Results: Eighty-three patients underwent EUS-PPG with 100% technical success. The mean PPG was 7.06 mmHg (SD 6.09, range 0-27.3). PPG was higher in patients with (vs without) clinical features of cirrhosis (9.46 vs 3.61 mmHg, P < 0.0001), esophageal or gastric varices (13.88 vs 4.34 mmHg, P < 0.0001), and thrombocytopenia (9.25 vs 4.71 mmHg, P = 0.0022). In the 71 patients (85.5%) who underwent EUS-bx, 70 (98.6%) specimens were deemed adequate by the pathologist for histologic diagnosis. There were no early or late major adverse events., Conclusion: EUS-PPG correlates well with clinical markers of PH. EUS-bx can be performed safely during the same session as EUS-PPG, providing a comprehensive endoscopic evaluation of the patient with CLD., (© 2022 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.)

Purpose: Noncardia gastric cancer (NCGC) is a leading cause of global cancer mortality, and is often diagnosed at advanced stages. Development of NCGC risk models within electronic health records (EHR) may allow for improved cancer prevention. There has been much recent interest in use of machine learning (ML) for cancer prediction, but few studies comparing ML with classical statistical models for NCGC risk prediction., Methods: We trained models using logistic regression (LR) and four commonly used ML algorithms to predict NCGC from age-/sex-matched controls in two EHR systems: Stanford University and the University of Washington (UW). The LR model contained well-established NCGC risk factors (intestinal metaplasia histology, prior Helicobacter pylori infection, race, ethnicity, nativity status, smoking history, anemia), whereas ML models agnostically selected variables from the EHR. Models were developed and internally validated in the Stanford data, and externally validated in the UW data. Hyperparameter tuning of models was achieved using cross-validation. Model performance was compared by accuracy, sensitivity, and specificity., Results: In internal validation, LR performed with comparable accuracy (0.732; 95% CI, 0.698 to 0.764), sensitivity (0.697; 95% CI, 0.647 to 0.744), and specificity (0.767; 95% CI, 0.720 to 0.809) to penalized lasso, support vector machine, K-nearest neighbor, and random forest models. In external validation, LR continued to demonstrate high accuracy, sensitivity, and specificity. Although K-nearest neighbor demonstrated higher accuracy and specificity, this was offset by significantly lower sensitivity. No ML model consistently outperformed LR across evaluation criteria., Conclusion: Drawing data from two independent EHRs, we find LR on the basis of established risk factors demonstrated comparable performance to optimized ML algorithms. This study demonstrates that classical models built on robust, hand-chosen predictor variables may not be inferior to data-driven models for NCGC risk prediction., Competing Interests: Yutaka TomizawaConsulting or Advisory Role: Boston Scientific, Medtronic Tina Hernandez-BoussardLeadership: Athelo HealthConsulting or Advisory Role: VerantosResearch Funding: AstraZeneca (Inst), Health Management Systems (Inst)Travel, Accommodations, Expenses: Health Management Systems Joo Ha HwangConsulting or Advisory Role: Olympus, Medtronic, Boston Scientific, MicrotechNo other potential conflicts of interest were reported.

Multimodality therapy including surgical resection is the current paradigm in treating malignant pleural mesothelioma (MPM), a thoracic surface cancer without cure. The main limitation of all surgical approaches is the lack of long-term durability because macroscopic complete resection (R1 resection) commonly predisposes to locoregional relapse. Over the years, there have been many studies that describe various intrapleural strategies that aim to extend the effect of surgical resection. The majority of these approaches are intraoperative adjuvants. Broadly, there are three therapeutic classes that employ diverse agents. The most common, widely used group of adjuvants are comprised of direct therapeutics such as intracavitary chemotherapy (± hyperthermia). By comparison, the least commonly employed intrathoracic adjuvant is the class comprised of drug-device combinations like photodynamic therapy (PDT). But the most rapidly evolving (new) class with much potential for improved efficacy are therapeutics delivered by specialized drug vehicles such as a fibrin gel containing cisplatin. This review provides an updated perspective on pleural-directed adjuncts in the management of MPM as well as highlighting the most promising near-term technology breakthroughs., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Choi, Singh, Wang, Pittala and Hoang.)

Long-term continuous-flow left ventricular assist device (CFLVAD) therapy is limited by complications. Compared with stroke and renal dysfunction, post-CFLVAD bowel ischemia is poorly characterized. Adult patients who underwent first-time durable CFLVAD implantation at our institution between 2008 and 2018 were identified and screened for bowel ischemia using Current Procedural Terminology codes for abdominal surgical exploration and International Classification of Disease codes for intestinal vascular insufficiency. Patients who developed biopsy-proven bowel ischemia (cases) were matched to controls (1:1, nearest neighbor, caliper = 0.29) based on preoperative characteristics. Incidences of postoperative right heart failure and renal replacement therapy were compared using McNemar's test. One year survival was estimated using the Kaplan-Meier method. Overall, 711 patients underwent CFLVAD implantation. Nineteen (2.7%) developed bowel ischemia (cases) median 17 days postimplantation (IQR 8-71). The majority of cases were male (78.9%), Black (63.2%), received HeartMate II (57.9%), treated as destination therapy (78.9%), and had a history of hypertension (89.5%), chronic kidney disease (84.2%), hyperlipidemia (84.2%), smoking (78.9%), and atrial fibrillation (57.9%). Post-LVAD, case patients were more likely to develop moderate-severe right heart failure (89.5% vs. 68.4%, p = 0.005), require renal replacement therapy (21.1% vs. 0%, p < 0.001), and less likely to survive to discharge (52.6% vs. 89.5%, p = 0.02) compared with controls. Case subjects demonstrated worse 1 year survival. While less common than stroke and renal dysfunction, post-CFLVAD bowel ischemia is associated with high 1 year mortality. Multi-institutional registries should consider reporting abdominal complications such as bowel ischemia as an adverse event to further investigate these trends and identify predictors of this complication to reduce patient mortality., (Copyright © ASAIO 2021.)

Objective: The objective of this study was to examine early lung transplant outcomes following EVLP using a large national transplant registry., Summary of Background Data: Lung transplantation in the United States continues to be constrained by a limited supply of donor organs. EVLP has the potential to significantly increase the available pool of donor lung allografts through the reconditioning of "marginal" organs., Methods: The united network for organ sharing registry was queried for all adults (age ≥18) who underwent first-time lung transplantation between March 2018 (when united network for organ sharing began collecting confirmed donor EVLP status) and June 2019. Transplants were stratified by EVLP use. The primary outcome was short-term survival and secondary outcomes included acute rejection before discharge and need for extracorpo-real membrane oxygenation support post-transplant., Results: A total of 3334 recipients met inclusion criteria including 155 (5%) and 3179 (95%) who did and did not receive allografts that had undergone EVLP, respectively. On unadjusted descriptive analysis, EVLP and non-EVLP cohorts had similar 180-day survival (92% vs 92%, P = 0.9). EVLP use was associated with a similar rate of acute rejection (13% vs 9%, P = 0.08) but increased rate of early extracorporeal membrane oxygenation use (12% vs 7%, P = 0.04). After adjustment, EVLP use was not associated with significantly increased mortality (adjusted hazard ratio 0.99, 95% confidence interval 0.62-1.58) or acute rejection (adjusted odds ratio 0.89, 95% confidence interval 0.40-1.97) compared to non-EVLP use., Conclusions: In the largest national series of EVLP lung transplant recipients, EVLP is associated with early recipient outcomes comparable to that of non-EVLP recipients with similar baseline characteristics. Longer term follow-up data is needed to further assess the impact of EVLP on post-lung transplant outcomes., Competing Interests: The authors have no relevant disclosures or conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Malignant pleural mesothelioma (MPM) is an aggressive and recalcitrant surface neoplasm that defies current multimodality treatments. MicroRNAs (miRNAs) are small noncoding RNAs that epigenetically regulate multiple gene networks and cellular processes. In cancer, miRNA dysregulation is associated with tumorigenesis, with tumor suppressor miRNAs underexpressed or lost, while oncogenic miRNAs are overexpressed. Consequently, miRNAs have emerged as potential therapeutic candidates. Because loss of tumor suppressors predominates the pathophysiology of MPM, re-expressing tumor suppressor miRNAs could be an effective therapeutic strategy. This review highlights the most promising MPM-specific tumor suppressor miRNAs that could be developed into novel therapeutics, the supporting data, and what is known about their molecular mechanism(s)., Competing Interests: Conflicts of interest All authors declared that there are no conflicts of interest.

We refined and replicated an efficacious brief intervention to reduce internalized homonegativity (IH) with a sample of gay and exclusively same-sex attracted men recruited from outside of LGBT community networks using Amazon Mechanical Turk. We sought to 1) determine if levels of IH differed between the original study's community-based sample and our non-community-based sample, 2) examine the efficacy of the replicated intervention, and 3) assess for longitudinal effects of the intervention at a 30-day follow-up. Four hundred eighty-four participants completed either the intervention or a stress management control condition. Mean levels of IH were higher in the current sample compared with the earlier study's community sample. The intervention was efficacious at reducing global IH, reducing personal homonegativity, and increasing gay affirmation. Ninety-six participants completed the follow-up; follow-up results were not significant and may have been affected by high rates of attrition. Implications for research and practice are discussed.
