Abstract
BACKGROUND Wolfram syndrome type 1 gene (WFS1), which encodes a transmembrane structural protein (wolframin), is essential for several biological processes, including proper inner ear function. Unlike the recessively inherited Wolfram syndrome, WFS1 heterozygous variants cause DFNA6/14/38 and wolfram-like syndrome, characterized by autosomal dominant nonsyndromic hearing loss, optic atrophy, and diabetes mellitus. Here, we identified two WFS1 heterozygous variants in three DFNA6/14/38 families using exome sequencing. We reveal the pathogenicity of the WFS1 variants based on three-dimensional (3D) modeling and structural analysis. Furthermore, we present cochlear implantation (CI) outcomes in WFS1-associated DFNA6/14/38 and suggest a genotype-phenotype correlation based on our results and a systematic review. METHODS We performed molecular genetic test and evaluated clinical phenotypes of three WFS1-associated DFNA6/14/38 families. A putative WFS1-NCS1 interaction model was generated, and the impacts of WFS1 variants on stability were predicted by comparing intramolecular interactions. A total of 62 WFS1 variants associated with DFNA6/14/38 were included in a systematic review. RESULTS One variant is a known mutational hotspot variant in the endoplasmic reticulum (ER)-luminal domain WFS1(NM_006005.3) (c.2051 C > T:p.Ala684Val), and the other is a novel frameshift variant in transmembrane domain 6 (c.1544_1545insA:p.Phe515LeufsTer28). The two variants were pathogenic, based on the ACMG/AMP guidelines. Three-dimensional modeling and structural analysis show that non-polar, hydrophobic substitution of Ala684 (p.Ala684Val) destabilizes the alpha helix and contributes to the loss of WFS1-NCS1 interaction. Also, the p.Phe515LeufsTer28 variant truncates transmembrane domain 7-9 and the ER-luminal domain, possibly impairing membrane localization and C-terminal signal transduction. The systematic review demonstrates favorable outcomes of CI. Remarkably, p.Ala684Val in WFS1 is associated with early-onset severe-to-profound deafness, revealing a strong candidate variant for CI. CONCLUSIONS We expanded the genotypic spectrum of WFS1 heterozygous variants underlying DFNA6/14/38 and revealed the pathogenicity of mutant WFS1, providing a theoretical basis for WFS1-NCS1 interactions. We presented a range of phenotypic traits for WFS1 heterozygous variants and demonstrated favorable functional CI outcomes, proposing p.Ala684Val a strong potential marker for CI candidates.

Clinical outcomes of withdrawing one medication from long-term combination therapy comprising α-blocker and 5α-reductase inhibitor for benign prostatic hyperplasia. Int Urol Nephrol 2023; 55:845-851. [PMID: 36763223 DOI: 10.1007/s11255-023-03476-6] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2022] [Accepted: 01/18/2023] [Indexed: 02/11/2023]
Abstract
PURPOSE To assess adherence to combination therapy comprising α-adrenergic blocker (AB) and 5α-reductase inhibitor (5ARI) for benign prostatic hyperplasia (BPH) in a real-world setting and whether lower urinary tract symptoms (LUTS) will relapse after discontinuing one medication from long-term combination therapy. METHODS BPH/LUTS patients receiving initial AB +5ARI combination therapy for at least 1 year between January 2012 and January 2017 were retrospectively analyzed. The patients were classified into DC-AB group (n = 65, AB discontinued) and DC-5ARI group (n = 77, 5ARI discontinued) and followed up. Clinical effects were assessed at baseline and annually using the International Prostatic Symptoms Score (IPSS), quality of life (QoL) index, total prostate volume (TPV), maximal flow rate (Qmax), and prostate-specific antigen (PSA) level. RESULTS Of total 1783 patients, 809 (45.4%) patients were identified with more than 1-year combination therapy. After withdrawal of one medication from combination therapy, the TPV progression (27.6% vs. - 10.8%; P < 0.001) and the requirement for prostate surgery (14.3% vs. 6.1%; P = 0.038) were significantly higher in the DC-5ARI group than in the DC-AB group. The rate of resuming combination therapy was significantly higher in the DC-5ARI group than in the DC-AB group (38.9% vs. 23.0%; P = 0.009). CONCLUSIONS Adherence to combination BPH therapy is relatively low. Although patients adhered to combination therapy for more than 1 year, a higher risk of requiring prostate surgery or resuming combination therapy was observed in patients who discontinued 5ARI.

Abstract
BACKGROUND This study compared the surgical outcomes of transoral endoscopic thyroidectomy vestibular approach (TOETVA) and transoral robotic thyroidectomy (TORT) in papillary thyroid cancer (PTC). METHODS The TOETVA and TORT groups comprised 119 and 121 patients between November 2016 and May 2022. Clinico-surgical outcomes and operation times were retrospectively reviewed. RESULTS The TORT group showed a higher number of retrieved central compartment lymph nodes, shorter hospital stays, and lower pain score after 48 h than the TOETVA group. No significant difference was observed in the other postoperative complications, including permanent vocal cord palsy. Total operation, working space creation, and endoscopic or robotic surgery times of the TORT group were longer than those of the TOETVA group. CONCLUSIONS TORT and TOETVA are feasible and safe. TORT may have some advantages, such as central compartment node dissection, shorter hospital stays, and pain score after 48 h in PTC, despite a longer operative time.

Abstract
We report on measurements of sequential ϒ suppression in Au+Au collisions at sqrt[s_{NN}]=200 GeV with the STAR detector at the Relativistic Heavy Ion Collider (RHIC) through both the dielectron and dimuon decay channels. In the 0%-60% centrality class, the nuclear modification factors (R_{AA}), which quantify the level of yield suppression in heavy-ion collisions compared to p+p collisions, for ϒ(1S) and ϒ(2S) are 0.40±0.03(stat)±0.03(sys)±0.09(norm) and 0.26±0.08(stat)±0.02(sys)±0.06(norm), respectively, while the upper limit of the ϒ(3S) R_{AA} is 0.17 at a 95% confidence level. This provides experimental evidence that the ϒ(3S) is significantly more suppressed than the ϒ(1S) at RHIC. The level of suppression for ϒ(1S) is comparable to that observed at the much higher collision energy at the Large Hadron Collider. These results point to the creation of a medium at RHIC whose temperature is sufficiently high to strongly suppress excited ϒ states.

Abstract
BACKGROUND This study evaluated the association between the extent of diffusion restriction on brain diffusion-weighted imaging (DWI) and neurological outcomes in patients who underwent targeted temperature management (TTM) after an out-of-hospital cardiac arrest (OHCA). METHODS Patients who underwent brain magnetic resonance imaging within 10 days of OHCA between 2012 and 2021 were analysed. The extent of diffusion restriction was described according to the modified DWI Alberta Stroke Program Early Computed Tomography Score (DWI-ASPECTS). The 35 predefined brain regions were assigned a score if diffuse signal changes were concordantly present in DWI scans and apparent diffusion coefficient maps. The primary outcome was an unfavourable neurological outcome at 6 months. The sensitivity, specificity, and receiver operating characteristic (ROC) curves for the measured parameters were analysed. Cut-off values were determined to predict the primary outcome. The predictive cut-off DWI-ASPECTS was internally validated using five-fold cross-validation. RESULTS Of the 301 patients, 108 (35.9%) had 6-month favourable neurological outcomes. Patients with unfavourable outcomes had higher whole-brain DWI-ASPECTS (median, 31 [26-33] vs. 0 [0-1], P < 0.001) than those with favourable outcomes. The area under the ROC curve (AUROC) of whole-brain DWI-ASPECTS was 0.957 (95% confidence interval [CI] 0.928-0.977). A cut-off value of ≥8 for unfavourable neurological outcomes had specificity and sensitivity of 100% (95% CI 96.6-100) and 89.6% (95% CI 84.4-93.6), respectively. The mean AUROC was 0.956. CONCLUSION More extensive diffusion restriction on DWI-ASPECTS in patients with OHCA who underwent TTM was associated with 6-month unfavourable neurological outcomes.

Abstract
BACKGROUND There has been no comparison of the prognoses of Korean patients who underwent curative surgery for cancer located at the cardia or subcardia of the stomach. We performed this comparison and further investigated the prognostic significance of esophagogastric junction (EGJ) invasion in patients. METHODS The medical records of patients (n = 511) who were diagnosed with cardia or subcardia cancer and underwent surgery between January 2010 and May 2019 were retrospectively reviewed. Patients were further categorized into four groups for analysis: subcardia gastric cancer (sGC; subcardia cancer without EGJ invasion; n = 97), AEG (adenocarcinoma of the esophagogastric junction) type III (subcardia cancer with EGJ invasion, n = 54), AEG type II without EGJ invasion (n = 158), and AEG type II with EGJ invasion (n = 202). We compared the overall survival of the four groups using a gastric cancer staging system and evaluated the prognostic significance of EGJ invasion with multivariate analysis. RESULTS The median follow-up of patients was 46.0 months (range: 0-124 months). There was significant difference in overall survival curves among the four groups (p < 0.001). Subgroup analysis showed a significant difference in overall survival between the groups with and without EGJ invasion (p < 0.001). Cancers with EGJ invasion were more frequently in the cardia (p < 0.001), had a larger size (p < 0.001), and showed a more advanced pathologic stage (stages II and III; 67.6% versus 33.7%, p < 0.001) than those without EGJ invasion. EGJ invasion and the pathologic stage were significant independent prognostic factors of overall survival in cardia and subcardia cancer patients (hazard ratio 2.24, 95% confidence interval 1.32-3.81, p = 0.003). CONCLUSION The overall survival between patients with cardia or subcardia cancer was significantly different according to EGJ invasion. EGJ invasion was an independent prognostic factor and should be considered for staging. Additional research is needed to apply this feature to gastric and esophageal cancer classification.

Abstract
Mechanically stretchable strain sensors gain tremendous attention for bioinspired skin sensation systems and artificially intelligent tactile sensors. However, high-accuracy detection of both strain intensity and direction with simple device/array structures is still insufficient. To overcome this limitation, an omnidirectional strain perception platform utilizing a stretchable strain sensor array with triangular-sensor-assembly (three sensors tilted by 45°) coupled with machine learning (ML) -based neural network classification algorithm, is proposed. The strain sensor, which is constructed with strain-insensitive electrode regions and strain-sensitive channel region, can minimize the undesirable electrical intrusion from the electrodes by strain, leading to a heterogeneous surface structure for more reliable strain sensing characteristics. The strain sensor exhibits decent sensitivity with gauge factor (GF) of ≈8, a moderate sensing range (≈0-35%), and relatively good reliability (3000 stretching cycles). More importantly, by employing a multiclass-multioutput behavior-learned cognition algorithm, the stretchable sensor array with triangular-sensor-assembly exhibits highly accurate recognition of both direction and intensity of an arbitrary strain by interpretating the correlated signals from the three-unit sensors. The omnidirectional strain perception platform with its neural network algorithm exhibits overall strain intensity and direction accuracy around 98% ± 2% over a strain range of ≈0-30% in various surface stimuli environments.

Beam Energy Dependence of Fifth- and Sixth-Order Net-Proton Number Fluctuations in Au+Au Collisions at RHIC. PHYSICAL REVIEW LETTERS 2023; 130:082301.

Abstract
We report the beam energy and collision centrality dependence of fifth and sixth order cumulants (C_{5}, C_{6}) and factorial cumulants (κ_{5}, κ_{6}) of net-proton and proton number distributions, from center-of-mass energy (sqrt[s_{NN}]) 3 GeV to 200 GeV Au+Au collisions at RHIC. Cumulant ratios of net-proton (taken as proxy for net-baryon) distributions generally follow the hierarchy expected from QCD thermodynamics, except for the case of collisions at 3 GeV. The measured values of C_{6}/C_{2} for 0%-40% centrality collisions show progressively negative trend with decreasing energy, while it is positive for the lowest energy studied. These observed negative signs are consistent with QCD calculations (for baryon chemical potential, μ_{B}≤110 MeV) which contains the crossover transition range. In addition, for energies above 7.7 GeV, the measured proton κ_{n}, within uncertainties, does not support the two-component (Poisson+binomial) shape of proton number distributions that would be expected from a first-order phase transition. Taken in combination, the hyperorder proton number fluctuations suggest that the structure of QCD matter at high baryon density, μ_{B}∼750 MeV at sqrt[s_{NN}]=3 GeV is starkly different from those at vanishing μ_{B}∼24 MeV at sqrt[s_{NN}]=200 GeV and higher collision energies.

However, if sternotomy has a prohibitive surgical risk, LVAD implantation can be performed through only left thoracotomy. We managed a patient with endstage heart failure who had recently undergone coronary artery bypass grafting (CABG) elsewhere. The patient also had a deep sternal wound infection and bacteremia. Because of refractory cardiogenic shock, we performed extracorporeal membrane oxygenation (ECMO). After multiple mediastinal washouts and omental flap placement, ECMO was converted to extracorporeal LVAD (from the left ventricular apex to the descending aorta) through a left thoracotomy. The extracorporeal LVAD was maintained for 18 days and replaced by the HeartMate 3 LVAD. The patient was discharged in good condition 115 days after CABG.

Immunopathological mechanisms in the early stage of Mycobacterium avium subsp. paratuberculosis infection via different administration routes in a murine model. PLoS One 2023; 18:e0281880.

Abstract
Mycobacterium avium subspecies paratuberculosis (MAP) is the causative agent of Johne's disease, a chronic emaciating disease of ruminants that causes enormous economic losses to the bovine industry, globally. However, there are still remaining clues to be solved in the pathogenesis and diagnosis of the disease. Therefore, an in vivo murine experimental model was tried to understand responses in early stage of MAP infection by oral and intraperitoneal (IP) routes. In the MAP infection size, and weight of spleen and liver were increased in the IP group compared with oral groups. Severe histopathological changes were also observed in the spleen and liver of IP infected mice at 12 weeks post-infection (PI). Acid-fast bacterial burden in the organs was closely related to histopathological lesions. In the cytokine production from splenocytes of MAP-infected mice, higher amounts of in TNF-α, IL-10, and IFN-γ were produced at early stage of IP-infected mice while IL-17 production was different at time and infected groups. This phenomenon may indicate the immune shift from Th1 to Th17 through the time course of MAP infection. Systemic and local responses in the MAP-infection were analyzed by using transcriptomic analysis in the spleens and mesenteric lymph nodes (MLN). Based on the analysis of biological processes at 6 weeks PI in spleen and MLN in each infection group, canonical pathways were analyzed with ingenuity pathway analysis in the immune responses and metabolism especially lipid metabolism. Infected host cells with MAP increased in the production of proinflammatory cytokines and reduced the availability of glucose at early stage of infection (p < 0.05). Also, host cells secreted cholesterol through cholesterol efflux to disturb energy source of MAP. These results reveal immunopathological and metabolic responses in the early stage of MAP infection through the development of a murine model.

Aortic Valve Replacement and Concomitant Multi-Vessel Coronary Artery Bypass: The Impact of Using the Bilateral Internal Thoracic Arteries on Early and Late Clinical Outcomes. J Chest Surg 2023; 56:197-203. [PMID: 36792942 PMCID: PMC10165424 DOI: 10.5090/jcs.22.122] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 12/02/2022] [Accepted: 12/22/2022] [Indexed: 02/17/2023] Open
Abstract
Background The survival benefit of coronary artery bypass grafting (CABG) using the bilateral internal thoracic arteries (BITA) is well known; however, the role of BITA in concomitant aortic valve replacement (AVR) and CABG has not been studied. Methods We retrospectively reviewed patients who underwent concomitant AVR and CABG. Cases not using an internal thoracic artery and less than 2 bypass grafts were excluded. We enrolled 114 patients in this study. The mean follow-up duration was 61.5±43.5 months. Results Forty patients (35.1%) underwent CABG with a single internal thoracic artery (SITA) and 74 patients (64.9%) underwent CABG with BITA. The preoperative clinical characteristics were not significantly different between the 2 groups, with the exception of a higher prevalence of atrial fibrillation in the SITA group. Postoperative mortality and morbidity were not significantly higher in the BITA group than in the SITA group. In the univariable analysis, the survival of the BITA group was similar to that of the SITA group (p=0.157). Multivariable analysis showed that only mean age was a predictor of death (p=0.042), but using BITA was not an independent predictor (p=0.094). In low-risk patients whose preoperative ejection fraction was >45%, the survival of the BITA group was significantly better than that of the SITA group (p=0.043). Conclusion BITA use in concomitant AVR and CABG showed no difference in mortality compared to using SITA. Although its impact on long-term survival was inconclusive, BITA use can be considered for low-risk patients.

Abstract
AIM The present study was conducted to assess the relationship between hyperuricemia and anemia in Korean adults with or without metabolic syndrome (MetS). METHODS Data from 6073 adults (age ≥ 20 years) in the Eighth Korean National Health and Nutrition Examination Survey (2019) were analyzed. RESULTS Several key findings were identified. First, after adjusting for the related variables, the hemoglobin [Hb] level in the hyperuricemia subgroup (uric acid [UA] ≥ 7.0 mg/dL in men or ≥ 6.0 mg/dL in women) was higher than in the normouricemia subgroup (UA < 7.0 mg/dL in men or < 6.0 mg/dL in women) in subjects with non-MetS (p = 0.005), whereas it was lower than in the normouricemia subgroup in subjects with MetS (p = 0.032). Second, after adjusting for the related variables, the odds ratio (OR) of anemia (Hb < 13.0 g/dL in men or < 12 g/dL in women), using the normouricemia subgroup as a reference, was negatively significant for the hyperuricemia subgroup in subjects with non-MetS (OR, 0.478; 95 % CI, 0.300-0.761) but positively significant for the hyperuricemia subgroup in subjects with MetS (OR, 1.765; 95 % CI, 1.160-2.198). CONCLUSIONS Hyperuricemia was associated with a decrease in anemia in non-MetS but an increase in anemia in MetS.

Abstract
This study compared the effects of extracorporeal cardiopulmonary resuscitation (ECPR) using propensity-score matching (PSM) analyses. A nationwide registry of out-of-hospital cardiac arrest (OHCA) patients in Korea between 2013 and 2016 was used. Patients with OHCA aged ≥15 years with cardiac etiology and resuscitation time >30 minutes were enrolled. Resuscitation-related variables before the initiation of ECPR were included. Two PSM analyses were performed separately, with and without post-ECPR variables. The primary outcome (PO) was a favorable neurologic outcome at hospital discharge. The rate of PO was 8.1% (13/161) in the ECPR group and 1.5% (247/16,489) in the conventional CPR (CCPR) group. In the matched cohort with post-ECPR variables, there was no significant difference in the rate of PO between the ECPR and CCPR groups (7.9% vs. 7.9%; p = 0.982). In the matched cohort without post-ECPR variables, the rate of PO was higher in the ECPR group than that in the CCPR group (8.3% vs. 3.6%; p = 0.012). PSM analysis without post-ECPR variables compared outcomes of all patients experiencing OHCA and treated with ECPR versus CCPR, which showed better neurologic outcomes for ECPR. PSM analysis with post-ECPR variables compared outcomes between ECPR survivors and CCPR survivors, which exhibited similar neurologic outcomes.

Trends in vitamin D level and risk of vitamin D deficiency after gastrectomy for gastric cancer: A retrospective study of a single high-volume center experience. Clin Nutr ESPEN 2023; 53:74-79. [PMID: 36657933 DOI: 10.1016/j.clnesp.2022.11.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 10/17/2022] [Accepted: 11/14/2022] [Indexed: 12/05/2022]
Abstract
BACKGROUND & AIMS Post-gastrectomy vitamin D deficiency can result in osteoporosis and fractures, which can decrease patient quality of life and increase their socioeconomic burden. However, because there is no consensus around preoperative measurement and regular postoperative monitoring of serum vitamin D [25(OH)vitD] level for gastric cancer patients, we performed a retrospective study with a single high-volume center experience. METHODS We reviewed a database of 614 gastric cancer patients who underwent curative gastrectomy between December 2015 and December 2019. Multivariate analyses were performed to identify risk factors for 25(OH)vitD deficiency after one year postoperative (n = 546). A linear mixed model was used to evaluate changes between preoperative (n = 585) and postoperative (6 [n = 504] and 12 months [n = 572]) 25(OH)vitD values. RESULTS Preoperative 25(OH)vitD deficiency occurred in 67.7% of patients with gastric cancer. Patients who underwent postoperative chemotherapy for advanced pathologic disease were more likely to be 25(OH)vitD deficient at postoperative year one than those who did not receive chemotherapy (P = 0.005). Postoperative chemotherapy was an independent risk factor along with preoperative 25(OH)vitD level for one year postoperative 25(OH)vitD deficiency (P = 0.002). Meanwhile, there was significant change in 25(OH)vitD level after surgery according to reconstruction (increased in Billroth I group compared to gastrojejunostomy group, P = 0.016), pathologic stage (increased in stage I group, decreased in stage II and III group, P = 0.005), postoperative chemotherapy (increased in non-chemotherapy group, decreased in chemotherapy group, P = 0.001), and season of surgery (increased when the blood tests were performed at summer, decreased when tested in non-summer season, P = 0.009). CONCLUSION More than half of gastric cancer patients had preoperative 25(OH)vitD deficiency, and those who had postoperative chemotherapy were at risk for 25(OH)vitD deficiency one year after surgery. There was a significant change in 25(OH)vitD level after surgery according to reconstruction method and postoperative chemotherapy. Preoperative measurement and regular postoperative monitoring should be considered for high-risk patients.

Abstract
BACKGROUND The aims of this study are to review data on 4-months age National Health Screening Program for Infants and Children (NHSPIC) using a National Health Insurance Service (NHIS) database, and to analyze the newborn hearing screening (NHS) results and related characteristics of the 4-months NHSPIC for 7 years in South Korea. METHODS We analyzed a NHIS database of infants who had participated in the 4-month age NHSPIC from 2010 to 2016. According to the results of hearing questionnaires and physical examination, we analyzed the outcomes of NHS and related infantile and socioeconomic factors. RESULTS Among 3,128,924 of total eligible infants in Korea between the year 2010 and 2016, 69.2% (2,164,621 infants) conducted 4-months age NHSPIC, and 94.4% (2,042,577 infants) of which performed hearing questionnaires regarding NHS. Among the total hearing examinees, premature infants accounted for 3.6%, infants who were hospitalized in the neonatal intensive care unit (NICU) for more than 5 days accounted for 5.6%, and infants with head and neck abnormalities were 0.6%. The NHS performing rate was 79.1% for total hearing examinees in 2010, but gradually increased to 88.9% in 2016. The NHS performing rate in 2016 was 93.4% for premature infants, 91.7% for NICU hospitalized babies. The mean referral rate was 0.6% for total hearing examinees, 1.4% for premature infants, and 2.3% for NICU hospitalized babies. When we analyzed the NHS performing rate and the referral rate according to the household income level, the NHS performing rate of infants in Medical Aid programs was the lowest as 65.6%, and the NHS performing rates in other five levels of NHIS was higher ranging between 85.1% to 86.0%. The referral rate of infants in the Medical Aid program (3.8%) was significantly higher than those of infants in other classes (1.10-1.25%). CONCLUSION The estimated overall NHS performing rate in Korea gradually increased and was 88.9% in 2016. The overall referral rate was low as 0.6%, and it was significantly different depending on the infant's health condition and household income levels. We assume that our finding would help to establish policies managing hearing impaired children, and to develop the customized hearing care service programs considering the household economic levels.

Abstract
Background Complete surgical excision is the only curative treatment for primary cardiac tumors. For wide excision, interatrial septal reconstruction (ISR) is commonly performed. We hypothesized that ISR may increase the risk of postoperative atrial tachyarrhythmia (AT) after surgical resection of cardiac myxoma. Methods After excluding patients with a history of cardiac surgery and concomitant procedures unrelated to tumor resection and those with AT or permanent pacemakers, we finally enrolled 272 adult patients who underwent benign cardiac tumor surgery from 1995 to 2021 at our institution. They were divided into the ISR (n=184) and non-ISR (n=88) groups. The primary outcome was postoperative new-onset AT. Results The study cohort predominantly consisted of women (66.2%), with a mean age of 57.2±13.6 years. The incidence of postoperative new-onset AT was 15.4%. No 30-day mortality or recurrence was observed. The cardiopulmonary bypass time and aortic cross-clamping time were significantly longer in the ISR group than in the non-ISR group (p<0.001). The median duration of hospital stay of all patients was 6.0 days (interquartile range, 5.0-7.0 days), and no significant difference was observed between the 2 groups (p=0.329). ISR was not an independent predictor of new-onset AT (p=0.248). Male sex and hypertension were found to be independent predictors of new-onset AT. Conclusion ISR was not a significant predictor of postoperative new-onset AT. ISR might be a feasible and safe procedure for surgical resection of cardiac myxoma and should be considered if needed.

Abstract
Abstract
The cytokine TGF-β is a central regulator of tissue homeostasis and regeneration through multiple coordinated effects on epithelial, immune, and mesenchymal stromal systems. Malfunctions of TGF-β signaling cause fibrosis, immune dysfunction, and cancer. As part of its multifunctional program, TGF-β induces epithelial-mesenchymal transitions (EMTs). Carcinoma cells use TGF-β to undergo EMT and adopt a highly plastic phenotype that facilitates tumor growth and metastasis. Notably, TGF-β-induced EMTs in epithelial progenitor cells are accompanied by the expression of fibrogenic factors that activate fibroblasts to produce and remodel the extracellular matrix. This not only occurs during wound healing but also in lung adenocarcinoma (LUAD) and pancreatic adenocarcinoma (PDAC) cells, suggesting that EMT and fibrogenesis are parts of an orchestrated program. We recently showed that the transcription factor RAS-Responsive Element-Binding Protein 1 (RREB1) activated by RAS-MAPK signaling synergizes with SMADs to coordinately activate the expression of EMT transcription factor Snai1 and fibrogenic genes in carcinoma progenitors (Su et al Nature 2020). Using metastasis transplantation models, we have now found that both arms of the RREB1-dependent TGF-β responses are important for metastasis. Knockout of individual fibrogenic genes in cancer cells inhibited metastasis without altering the induction of EMT by TGF-β. To address why these TGF-β target genes specifically require KRAS-activated RREB1 for transcriptional induction, we employed proteomics approaches coupled with a CRISPR-based genetic screen. With this approach we identified DXH9 and INO80 as RREB1-interacting factors essential for TGF-β activation of fibrogenic EMT programs in PDAC and LUAD cells. DXH9 and INO80 are helicases that interact and SMAD3 and RREB1 in response to TGF-β. Knockout of Dhx9 or Ino80 abolished the induction of Snai1 and fibrogenic genes by TGF-β, inhibited the LUAD metastasis, and decreased intratumoral fibrosis, thus phenocopying the knockout of Rreb1. The helicase domain of DHX9 is required for TGF-β gene responses and metastasis. Our evidence indicates that RREB1, DXH9, and INO80 function to remodel the chromatin at specific loci that constitute a TGF-β-dependent fibrogenic EMT program. This work illuminates a previously unknown cooperation between TGF-β and RAS-MAPK pathways during epithelial tissue regeneration and its cooption in carcinoma metastasis.

Abstract
Background Patients with gastric cancer often encounter impaired quality of life and reduced tolerability to adjuvant treatments after surgery. Weight preservation is crucial for the overall prognosis of these patients, and exercise and supplemental nutrition play the main role. This study is the first randomized clinical trial to apply personalized, treatment stage-adjusted digital intervention with wearable devices in gastric cancer rehabilitation intervention for 12 months, commencing immediately after surgery. Methods This is a prospective, multicenter, two-armed, randomized controlled trial and aims to recruit 324 patients from two hospitals. Patients will be randomly allocated to two groups for 1 year of rehabilitation, starting immediately after the operation: a personalized digital therapeutic (intervention) group and a conventional education-based rehabilitation (control) group. The primary objective is to clarify the effect of mobile applications and wearable smart bands in reducing weight loss in patients with gastric cancer. The secondary outcomes are quality of life measured by the EORTC-QLQ-C30 and STO22; nutritional status by mini nutrition assessment; physical fitness level measured by grip strength test, 30-s chair stand test and 2-min walk test; physical activity measured by IPAQ-SF; pain intensity; skeletal muscle mass; and fat mass. These measurements will be performed on enrollment and at 1, 3, 6, and 12 months thereafter. Conclusions Digital therapeutic programs include exercise and nutritional interventions modified by age, body mass index, surgery type and postoperative days. Thus, expert intervention is pivotal for precise and safe calibration of this program.

Abstract
Sirtuins (SIRTs) belong to the nicotinamide adenine dinucleotide (NAD+)-dependent class III histone deacetylase family. They are key regulators of cellular and physiological processes, such as cell survival, senescence, differentiation, DNA damage and stress response, cellular metabolism, and aging. SIRTs also influence carcinogenesis, making them potential targets for anticancer therapeutic strategies. In this study, we investigated the anticancer properties and underlying molecular mechanisms of a novel SIRT1 inhibitor, MHY2251, in human colorectal cancer (CRC) cells. MHY2251 reduced the viability of various human CRC cell lines, especially those with wild-type TP53. MHY2251 inhibited SIRT1 activity and SIRT1/2 protein expression, while promoting p53 acetylation, which is a target of SIRT1 in HCT116 cells. MHY2251 treatment triggered apoptosis in HCT116 cells. It increased the percentage of late apoptotic cells and the sub-G1 fraction (as detected by flow cytometric analysis) and induced DNA fragmentation. In addition, MHY2251 upregulated the expression of FasL and Fas, altered the ratio of Bax/Bcl-2, downregulated the levels of pro-caspase-8, -9, and -3 proteins, and induced subsequent poly(ADP-ribose) polymerase cleavage. The induction of apoptosis by MHY2251 was related to the activation of the caspase cascade, which was significantly attenuated by pre-treatment with Z-VAD-FMK, a pan-caspase inhibitor. Furthermore, MHY2251 stimulated the phosphorylation of c-Jun N-terminal kinase (JNK), and MHY2251-triggered apoptosis was blocked by pre-treatment with SP600125, a JNK inhibitor. This finding indicated the specific involvement of JNK in MHY2251-induced apoptosis. MHY2251 shows considerable potential as a therapeutic agent for targeting human CRC via the inhibition of SIRT1 and activation of JNK/p53 pathway.

Abstract
BACKGROUND Clinical benefits of the meso-jejunal lymph node (MJLN) dissection in remnant gastric cancer (RGC) patients have not been fully established. Hence, in this retrospective study, we evaluated the survival benefit of MJLN dissection and prognostic significance of MJLN metastasis in RGC patients who underwent gastrojejunostomy reconstruction after their initial gastrectomy. METHODS We retrospectively reviewed 391 patients who underwent surgery for RGC at our institution between 1996 and 2019. Among them, 60 patients had MJLN dissection. The index value of the survival benefit gained by dissection of the MJLN was calculated by multiplying the frequency of metastasis at the MJLN station and the 5-year overall survival rate (5YOS) of patients with metastasis at that station. When the metastatic rate or 5YOS exceeded 10%, dissection was recommended. An index value of dissection greater than 1.0 was considered significant. RESULTS Total metastatic rate of MJLN was 35% (n = 21/60). Patients with MJLN metastasis had advanced pathologic stage compared to patients in the no-metastasis group (p < 0.001). In T2-T4 RGC patients, the metastatic rate of MJLN was 48.6% (n = 17/35), and their 5YOS was 28.4%. The calculated index value was 13.8. Also, patients with MJLN metastasis had a poorer overall survival than those without metastasis. MJLN metastasis was an independent prognostic factor of overall survival in multivariate analysis (HR 6.77, 95%CI 2.21-20.79, p = 0.001). CONCLUSION MJLN dissection should be considered for advanced RGC patients who underwent gastrojejunostomy after distal gastrectomy during their initial surgery according to the index value.

Abstract
OBJECTIVES We investigated the efficacy and safety of silkworm pupae extract (SWP) consumption for 12 weeks on muscle mass and strength in middle-aged and older individuals with relatively low skeletal muscle mass who do regular low-intensity exercise. DESIGN A randomized double-blinded placebo-controlled trial. PARTICIPANTS The study was conducted with 54 participants with relatively low skeletal muscle mass (SMM) (64.4 ± 6.1 years; body mass index, 23.8 ± 2.4 kg/m2). INTERVENTION AND MEASUREMENTS Participants were randomly assigned to one of two groups: 1000 mg of SWP/day plus regular exercise (SWP group, n=27) or placebo plus regular exercise (placebo group, n=27). All participants were required to engage in 30-60 minutes/day of walking for ≥3 days/week for 12 weeks. The primary outcome was knee extension/flexion strength (Nm), measured at the velocity of 60°/s. Secondary outcomes included body composition, biomarkers (creatine kinase and creatinine), handgrip strength, and quality of life questionnaire. RESULTS Both the intention-to-treat (ITT) and per-protocol (PP) analyses revealed no significant impact of SWP on knee strength compared to the placebo group over 12 weeks. On the other hand, the SWP group had significantly greater increases in right-handgrip strength by 1.94 kg (95% CI: 0.08-3.79; p = 0.041) and left-handgrip strength by 1.83 kg (0.25-3.41; p = 0.024) compared to the placebo group in the ITT population, after 12 weeks. Moreover, in the PP population, the SWP group revealed an even greater increase in right-handgrip strength by 2.07 kg (0.15-3. 98; p = 0.035) and left-handgrip strength by 2.21 kg (0.60-3.83; p = 0.008) for the 12-week period. However, this study resulted in a failure to detect significant differences in the body composition, biomarkers, quality of life questionnaire, physical activity, and caloric intake between the groups. None of the participants in the SWP group experienced any significant adverse events. In the placebo group, two participants experienced urticaria and allergic side effects, leading to their withdrawal from the study and two exhibited elevated levels of liver enzyme and increased diastolic blood pressure, respectively at 12 weeks. CONCLUSION SWP, in addition to low-intensity exercise, may enhance handgrip strengths in middle-aged and older adults with relatively lower SMM. Future studies need to use a large sample size over longer periods to validate our findings. This trial was registered at clinicaltrials.gov as NCT04994054.

Transforaminal Epidural Steroid Injection for Patients with Lumbosacral Disc Herniation in the Absence of Spine Magnetic Resonance Imaging - Is Better Really the Enemy of the Best? J Pain Res 2023; 16:1477-1485. [PMID: 37168846 PMCID: PMC10166140 DOI: 10.2147/jpr.s402405] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2023] [Accepted: 05/02/2023] [Indexed: 05/13/2023] Open
Abstract
Purpose This study aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) in patients with lumbosacral disc herniation by comparing its effect between those diagnosed by clinical evaluation and plain radiography only (X-ray group) and those by additional magnetic resonance imaging (MRI) (MRI group). Additionally, we investigated the accuracy of the preliminary clinical assumption in the X-ray group using confirmative post-injection MRI. Patients and Methods We retrospectively recruited 367 patients with back and radicular pain due to lumbosacral disc herniation from a single pain clinic. Among them, 201 and 166 patients were categorized into the X-ray and MRI groups, respectively. In the X-ray group, the pathological level assumed initially by clinical evaluation and plain radiography concurred with that confirmed later on post-injection MRI in 139 patients (corresponding group); the remaining 62 patients lacked this concurrence (non-corresponding group). The NRS scores and Macnab criteria results were compared between the X-ray and MRI groups as well as the corresponding and non-corresponding groups. Results Both the X-ray and MRI groups showed significant reductions in the NRS scores at 2 and 10 weeks post-injection when compared with the pretreatment scores. However, no significant difference was noted between the groups in terms of the magnitude of clinical improvement assessed by successful reduction in the NRS or Macnab scores. Furthermore, similar results were obtained in the comparison between the corresponding and non-corresponding groups of the X-ray group. Conclusion TFESI guarantees favorable clinical outcomes even in the absence of confirmative MRI in patients with back and radicular pain. The preemptive application of this procedure could be prioritized and justified in patients suspected of lumbosacral disc herniation based on clinical evaluation and plain radiography only without the preceding MRI verification.

J Pharmacopuncture 2022; 25:396-403. [PMID: 36628347 PMCID: PMC9806156 DOI: 10.3831/kpi.2022.25.4.396] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/20/2022] [Revised: 10/24/2022] [Accepted: 12/08/2022] [Indexed: 12/30/2022] Open
Abstract
Objectives Gout is an inflammatory arthritis of the joints and soft tissues occurring due to deposition of monosodium urate (MSU) crystals, which are caused by persistent hyperuricemia. Soyeom pharmacopuncture is one treatment method that has been traditionally used for pain management in Oriental medicine. However, studies on its effect in reducing gout pain have been insufficient. Therefore, we selected Soyeom pharmacopuncture among natural products used in Korea as the new target of our study. Methods The effects of Soyeom pharmacopuncture were examined in mouse models of acute gout induced by injection of MSU crystals into footpads. IL-1β, IL-6, and TNF-α production were examined by immunoblotting and enzyme-linked immunosorbent assay as hallmarks of NLRP3 inflammasome and cytokine activation. Results Soyeom pharmacopuncture reduced foot edema in gout-induced mice, as well as IL-1β, nitrite, IL-6, and TNF-α production. Moreover, Soyeom pharmacopuncture also reduced MSU-induced gout inflammatory gene expressions, specifically those in the NF-kB pathway. Conclusion Pharmacopuncture may serve as a new solution for other inflammatory diseases as well. Through active follow-up studies, we could thoroughly understand the clinical value of Soyeom pharmacopuncture.

Collision-System and Beam-Energy Dependence of Anisotropic Flow Fluctuations. PHYSICAL REVIEW LETTERS 2022; 129:252301. [PMID: 36608250 DOI: 10.1103/physrevlett.129.252301] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2022] [Revised: 08/17/2022] [Accepted: 11/16/2022] [Indexed: 06/17/2023]
Abstract
Elliptic flow measurements from two-, four-, and six-particle correlations are used to investigate flow fluctuations in collisions of U+U at sqrt[s_{NN}]=193 GeV, Cu+Au at sqrt[s_{NN}]=200 GeV and Au+Au spanning the range sqrt[s_{NN}]=11.5-200 GeV. The measurements show a strong dependence of the flow fluctuations on collision centrality, a modest dependence on system size, and very little if any, dependence on particle species and beam energy. The results, when compared to similar LHC measurements, viscous hydrodynamic calculations, and trento model eccentricities, indicate that initial-state-driven fluctuations predominate the flow fluctuations generated in the collisions studied.
