Abstract
BackgroundRecent studies showed the efficacy of multitarget therapy with mycophenolate mofetil (MMF) and calcineurin inhibitor for induction therapy for lupus nephritis (LN)1. However, long-term outcomes have not been well elucidated.ObjectivesWe retrospectively analyzed the long-term outcomes of multitarget therapy of MMF and tacrolimus.MethodsWe examined 27 LN patients (4 male, 23 female) treated with multitarget therapy for induction therapy between Oct. 2009 and Nov. 2018 in our department. Complete remission (CR) was defined as 1) UPCR<0.5 g/gCr, and 2) serum creatinine (S-Cr) normal or if abnormal, within 15% of baseline; 1) and 2) were observed in 2 consecutive visits. Relapse was defined as UPCR>1.0 g/gCr or intensification of immunosuppressive treatment after achievement of CR.ResultsThe mean age was 38.6±11.6 years old. 17 patients were new-onset LN, and 10 patients were relapse LN. UPCR and eGFR before treatment were 4.42±2.98 g/gCr and 71.5±32.9 mL/min/1.73m2, respectively. Renal histology was Class III in 1, III+V in 4, IV in 12. IV+V in 9 and V in 1 by ISN/RPS 2003 classification. CR at 6 and 12 months were 59% and 74%, respectively. Patients were treated by multitarget therapy for median of 25 months (IQR, 5.5-37). Finally, 26 (96%) patients achieved CR. During multitarget therapy, there were 15 serious adverse events: deep vein thrombosis in 2, myocardial infarctions in 2, cervical intraepithelial neoplasia in 2, heart failure in 1, herpes zoster in 1, viral myocarditis in 1, cytomegalovirus gastroenteritis in 1, cholecystitis in 1, pyelonephritis in 1, bacterial enteritis in 1, sepsis in 1, and breast cancer in 1. During the median observation period of 94 months (IQR, 63-111.5) after the initiation of multitarget therapy, 1 patient died due to sudden death. No patient reached end-stage kidney disease or doubling S-Cr. 16 patients relapsed at median of 32 months (IQR,13.8-64.5) after CR; 8 patients relapsed on multitarget therapy, and 8 patients relapsed after cessation of multitarget therapy. Relapse was associated with chronic lesions in renal biopsy and normal or higher C4 levels at treatment initiation by Kaplan Meier analysis (Log-rank, P=0.006, P<0.001, respectively).ConclusionMultitarget therapy effectively induced CR and maintained renal function in long-term period. However, relapse was often observed during or after withdrawal of multitarget therapy.References[1]Liu Z, Zhang H, Liu Z, et al.

Background
The presence of atrial fibrillation (AF) is associated with electrical remodeling processes that promote a substrate for the maintenance of AF itself. Small conductance Ca2+-activated K+ (SK) channels; K+-selective and voltage-independent ion channels are key factors in the atrial electrical remodeling (2, 3). However, the mechanism of its activation remains unclear. A recent study showed that neuronal nitric oxide synthase (nNOS) expression and activity are reduced in AF patients and that nNOS depletion causes the abbreviation of action potential duration (APD), leading to increased AF inducibility in animal experiments (4). Decreased NO production, especially driven by nNOS inhibition, might play a key role in the atrial electrical remodeling, and the downstream alteration of SK channels might result from this process.
Purpose
We aimed to evaluate the potential of SK channel blocking to mitigate abnormal electrophysiological properties and the inducibility of atrial tachyarrhythmia (ATA) which was induced by nNOS depletion, and to describe the related mechanism.
Methods
Atrial tachyarrhythmia induction and optical mapping were performed in perfused rat hearts. nNOS was pharmacologically inhibited by S-methylthiocitrulline (SMTC, 100 nM). The influence of the SK channel was examined by a specific channel inhibitor, apamin (100 nM). APD, conduction velocity, and calcium transient (CaT) parameters (CaTD, rise time, time to 50% decay, and tau) were evaluated by voltage and calcium dual optical mapping. Dominant frequency was evaluated to analyze the wave dynamics of AF.
Results
SMTC increased the inducibility of ATA and apamin mitigated the nNOS inhibition-induced arrhythmogenicity (0% [0/7] vs 62% [8/13] vs 15% [2/13] in control, SMTC and SMTC + apamin). SMTC caused the abbreviation and enhanced spatial dispersion of APD, which were reversed by apamin. In contrast, conduction velocity was not affected by SMTC or apamin. Moreover, apamin reduced the dominant frequency of SMTC-induced ATA. In voltage and calcium optical mapping, STMC and apamin did not alter the parameters associated with CaT, however, SMTC caused the abbreviation of APD, which was reversed by apamin (APD80: 48.4 ± 2.7 msec in control group, 30.8 ± 1.5 msec in SMTC group, p <0.0001 vs. control, 41.8 ± 1.5 msec in SMTC + apamin, p = 0.01 vs. SMTC by One-way ANOVA and Tukey’s multiple-comparison test) (Figure A-C).
Conclusion
Acute nNOS inhibition abbreviated APD via activating SK channels. A specific SK channel blocker mitigated APD abbreviation without the alteration of CaT, implying an underlying mechanism of post translational modification of SK channels.

Abstract
OBJECTIVES Endoscopic resection (ER) is indicated for a wide range of superficial esophageal squamous cell carcinomas (ESCCs). We examined the long-term outcomes in patients with pathological (p) invasion of ESCC into the T1a-muscularis mucosae (MM) and T1b-submucosa (SM) after ER, for which data on prognosis are limited. METHODS Of the 1217 patients with superficial ESCC who underwent ER, 225 patients with a pathological diagnosis of ESCC invasion into the MM, minute submucosal invasion ≤200 µm (SM1), or massive submucosal invasion (SM2) were included. In patients with lymphovascular invasion, droplet infiltration, or SM2 invasion, additional treatments, including chemoradiation (CRT) or esophagectomy with two- to three-field lymph node dissection, were recommended. The median observation period was 66 months (interquartile range 48-91 months). RESULTS In total, there were 151, 28, and 46 pT1a-MM, pT1b-SM1, and pT1b-SM2 cases, respectively. Metastatic recurrence was observed in 1.3%, 10.7%, and 6.5% patients with pT1a-MM, pT1b-SM1, and pT1b-SM2 ESCCs, respectively. Of the eight patients with metastatic recurrence, six were successfully treated, and two died of ESCC. The 5-year overall survival rates were 84.1%, 71.4%, and 67.4%, the 5-year relapse-free survival rates were 82.8%, 64.3%, and 65.2%, and the 5-year disease-specific survival rates were 100%, 96.4%, and 99.1% in patients with pT1a-MM, pT1b-SM1, and pT1b-SM2 ESCCs, respectively. Multivariate analysis showed that additional CRT and esophagectomy, and T1b-SM2 were positively and negatively associated with overall survival, respectively. CONCLUSIONS Endoscopic resection preceding appropriate additional treatments resulted in favorable outcomes. Many cases of metastatic recurrence in this cohort could be successfully treated.

Abstract
BACKGROUND McKeown esophagectomy with two-field lymphadenectomy is the treatment of choice for oncologic esophagectomy. A cervical drain is placed in cases after modern two-field lymph node dissection (M2FD) to provide information on anastomotic leakage. However, the necessity of prophylactic cervical drainage during surgery remains unknown. This study aimed to clarify the clinical significance of cervical drainage in patients who underwent McKeown esophagectomy with M2FD. METHODS A total of 293 patients underwent McKeown surgery with two-field lymphadenectomy at our institute between January 2013 and December 2019. We compared the day of drain removal, amount of drainage volume, and the appearance of drainage fluid between patients with and without anastomotic leakage. RESULTS McKeown esophagectomy reconstructed through the retrosternal route is 203 patients (69.3%) of all. Nineteen patients (6.5%) experienced anastomotic leakage. The amount of cervical drain discharge was comparable between patients with and without anastomotic leakage. In addition, no purulent or salivary discharge was observed in patients with anastomotic leakage. There was no difference in the median day of drain removal between the groups. The initial clinical findings for the diagnosis of anastomotic leakage were surgical site infection in 10 (52.6%), fever in 5 (26.3%), prolonged inflammation in a blood test in 3 (15.8%), and bloody discharge from the chest tube in 1 (5.3%). There was no mortality due to any cause. CONCLUSION A prophylactic cervical drain may not be mandatory in patients with esophageal cancer undergoing McKeown esophagectomy reconstructed through the retrosternal route with two-field lymphadenectomy.

Abstract
PURPOSE Although C-reactive protein to prealbumin ratio (CPR) can predict the outcomes of several types of cancer surgeries, little is known about the implication of CPR in patients undergoing esophagectomy for esophageal squamous cell carcinoma (ESCC). METHODS Between 2009 and 2018, 682 consecutive ESCC patients who underwent curative esophagectomy were enrolled. The clinicopathological factors and prognoses were compared between the groups stratified by preoperative CPR levels. A logistic regression model was used to determine the risk factors of postoperative pneumonia. Survival curves were constructed using the Kaplan-Meier method and compared using the log-rank test. The Cox proportional hazards model was used to elucidate prognostic factors. RESULTS There were more elderly patients, more males, and more advanced clinical T and N categories in the high CPR group than in the low CPR group. Also, the incidence of postoperative pneumonia was significantly higher in the high CPR group than in the low CPR group (32.4% vs. 20.3%, p < 0.01). In multivariate analyses, high CPR was one of the independent predictive factors for postoperative pneumonia (OR, 1.71; 95% CI, 1.15-2.54; p < 0.03). Moreover, high CPR was an independent prognostic factor for overall, cancer-specific, and recurrence-free survivals (HR 1.62; 95% CI 1.18-2.23; p < 0.01, HR 1.57; 95% CI 1.08-2.32; p = 0.02, HR 1.42; 95% CI 1.06-1.90; p = 0.02). CONCLUSION Preoperative CPR was found to be a useful inflammatory and nutritional indicator for predicting the occurrence of pneumonia and prognosis in patients with ESCC undergoing esophagectomy.

Abstract
Purpose: Intramural metastasis (IM) in esophageal squamous cell carcinoma (ESCC) is sometimes found, and the prognosis of ESCC patients with pathologically diagnosed IM is known to be dismal. However, there are few reports on ESCC patients with clinically diagnosed IM. Methods: This study assessed 2,772 ESCC patients who underwent endoscopy for initial evaluation. Among them, 85 patients (3.1%) were diagnosed with endoscopic IM. In this study, we investigated these patients’ characteristics, survival among the groups stratified by the treatment modalities, and survival predictors. Results: Of 85 patients, 76 (89.4%) had T3 or T4 tumors, 73 (85.9%) had nodal metastases, and 36 (42.4%) had M1 diseases. Curative-intent treatment could be given to 63 patients (74.1%) with a median survival time (MST) of 15.6 months (95% CI: 10.7-20.4). As initial treatment, upfront surgery (US), neoadjuvant chemotherapy (NAC) using cisplatin and 5-fluorouracil (CF), neoadjuvant chemoradiotherapy, and definitive chemoradiotherapy (dCRT) were given to 17 (27.0%), 27 (42.9%), 2 (3.2%), and 17 patients (27.0%), respectively. dCRT was preferred for T4 tumors compared with US or NAC (P = 0.02). The MST of US and NAC patients was 19.3 (95% CI: 12.9-25.6) and 23.4 months (95% CI: 9.4-37.4), respectively. No significant difference was noted between US and NAC patients (P= 0.89). Conclusion: The prognosis of ESCC patients with endoscopic IM is poor even if curative-intent treatment is done. Moreover, no significant survival benefit of NAC with CF for these patients was observed when compared with US.

Abstract
INTRODUCTION It is important to prevent the deterioration of activities of daily living to improve the long-term prognoses of patients in the intensive care unit (ICU). The patients' conditions, along with the lack of human and technical resources, often become barriers to achieving early mobilisation after the introduction of mechanical ventilation. We plan to verify the usefulness of a mobile patient lift for early mobilisation. METHODS AND ANALYSIS We will conduct a single-centre, open-label, randomised controlled trial. The inclusion criteria are as follows: age ≥18 years, independent walking before admission and expected mechanical ventilation for at least 48 hours. The participants will be randomly divided into groups with (intervention group) or without (control group) a mobile lift protocol. A mobile lift will be used in the intervention group. The primary endpoint will be the number of days required to achieve an ICU mobility scale of ≥4 (standing position). The results of the two groups will be analysed using the Student's t-test. ETHICS AND DISSEMINATION This study will be conducted in accordance with the Declaration of Helsinki and with the approval of the Toho University Omori Medical Center Ethics Committee (approval number M20259). The results of this study will be presented internationally at academic conferences and published in the literature. TRIAL REGISTRATION NUMBER UMIN000044965.

Abstract
BACKGROUND Prediction of tissue origin of esophagogastric junction (EGJ) adenocarcinomas can be important for therapeutic decision, but no molecular marker is available. Here, we aimed to develop such a marker taking advantage of tissue-specific profiles of DNA methylation. METHODS DNA methylation profiles of gastric adenocarcinomas (GACs) were obtained by an Infinium HumanMethylation450 BeadChip array, and those of esophageal adenocarcinoma (EACs) were obtained from the TCGA database. DNA from formalin-fixed paraffin-embedded (FFPE) samples was analyzed by bisulfite pyrosequencing. RESULTS In the screening set, 51 of 145,841 CpG sites in CpG islands were methylated at significantly higher levels in 30 GACs compared to those in 30 EACs. Among them, SLC46A3 and cg09177106 were unmethylated in all the 30 EACs. Predictive powers of these two markers were successfully confirmed in an independent validation set (18 GACs and 18 EACs) (SLC46A3, sensitivity = 77.8%, specificity = 100%; cg09177106, sensitivity = 83.3%, specificity = 94.4%), and could be applied to FFPE samples (37 GACs and 18 EACs) (SLC46A3, P = 0.0001; cg09177106, P = 0.0028). On the other hand, EAC-specific markers informative in the FFPE samples could not be isolated. Using these GAC-specific markers, nine of 46 (19.6%) TCGA EGJ adenocarcinomas were predicted to be GACs. CONCLUSIONS Two GAC-specific markers, SLC46A3 and cg09177106, had a high specificity for identifying the tissue origin of EGJ adenocarcinoma.

Background/Introduction: Congestive heart failure (CHF), the main reason for morbidity and mortality, is considered a serious consequence of myocardial infarction (MI). The use of left ventricular end-diastolic pressure (LVEDP) as a chief indicator of CHF becomes limited because of the possible impairment of cardiac function and induced aortic valve damage during its recording. Echocardiography is the gold standard approach to diagnose structural myocardial dysfunction. However, its ability to predict chronic CHF following MI is still limited. Recently, intraventricular pressure gradient (IVPG) was presented as a non-invasive, highly sensitive preload-independent diastolic function parameter to assess cardiac function, especially during cardiomyopathy. However, there have not been any investigations demonstrating the feasibility of IVPG in the evaluation of post-infarction chronic CHF.
Purpose
This study aimed to investigate the utility of IVPG to assess the heart function in a rat model with chronic CHF following MI with evaluating its capacity to predict these changes.
Methods
Fifty male rats were included. MI was induced via ligation of the left anterior descending artery (LAD) at the level of the atrioventricular junction (MI animals, n = 35). Sham animals were subjected to the same left thoracotomy procedure without LAD ligation (Sham animals, n = 15). Transthoracic conventional echocardiography and colour M-mode echocardiography (CMME) for IVPG were performed in all animals 6 months post-surgery. The next day, animals were anesthetized, ventilated, and euthanized after the recording of hemodynamics. The heart weight, and lung and liver wet-to-dry weight ratios were recorded. J-tree cluster-analysis was performed based on ten echocardiographic variables indicative of CHF.

Based on the cluster analysis, animals were joined into two clusters; CHF+ (n = 22) and named MI/HF+, and CHF- (n = 28) that was joined from sham (n = 15), and MI/HF- (n = 13). MI/HF+ presented the most severe anatomical and echocardiographic changes indicative of CHF with significant reduction of all IVPG indices and impairment of the hemodynamics. The IVPG indices were significantly (P< 0.0001) correlated with the anatomical and echocardiographic findings, LVDP, LVEDP, HR, -dP/dtmin, and Tau. Meanwhile, LVSP was only significantly correlated with apical IVPG (R = 0.677, P = 0.022). dP/dtmax was significantly correlated with total IVPG, basal IVPG, and apical IVPG (R = 0.797, P = 0.017, R = 0.724, P = 0.003, and R = 0.652, P = 0.026 ; respectively). Moreover, total, basal, mid-to-apical, mid-, and apical IVPG were significant (P< 0.0001) predictors of chronic CHF following MI.
Conclusion
Compared to the structural, and functional indices of conventional echocardiography, IVPG derived from CMME could provide a substantial non-invasive tool to diagnose and predict CHF after long-term MI.

Long-Term Insufficiency of Oral Intake after Esophagectomy; Who Needs Intense Nutritional Support after Esophagectomy? ANNALS OF NUTRITION AND METABOLISM 2022; 78:106-113. [PMID: 35038697 DOI: 10.1159/000521893] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2021] [Accepted: 01/09/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND Patients with esophageal cancer are at a high risk of malnutrition after esophagectomy, and nutritional support may at times be required for several months following surgery. In this study, we aimed to clarify the clinical features and preoperative risk factors of patients with long-term insufficiency of oral intake after esophagectomy by evaluating the duration of feeding enterostomy placement. METHODS A total of 306 patients who underwent esophagectomy, reconstruction with gastric conduit, and feeding enterostomy creation were retrospectively reviewed. We analyzed the clinical features and preoperative risk factors for long-term placement of feeding enterostomy. RESULTS The feeding enterostomy tube was removed less than 90 days after esophagectomy in 234 patients (76.5%) (Short group), whereas 72 patients still needed enteral nutrition after 90 days (23.5%; Long group). Although severe malnutrition was observed more frequently in the long group compared with the short group (p=0.021), overall survival time was comparable between the groups (p=0.239). Multivariate analysis revealed that higher age (OR 1.04; 95% CI, 1.01-1.07; p=0.021), poor performance status(OR 2.94; 95% CI, 1.10-7.87; p=0.032), and lower preoperative body weight(OR 0.96; 95% CI, 0.94-0.99; p=0.009) were the independent variables predicting the long-time placement of feeding enterostomy. CONCLUSION Nutritional support via feeding enterostomy for more than 90 days after esophagectomy was required in 23.5% of patients. The elderly, poor performance status, and lower body weight were the independent preoperative factors for predicting the long-term placement of feeding enterostomy.

Abstract
Fusobacterium nucleatum, found in the oral cavity, influences the progression of gastrointestinal cancers. Additionally, our previous results suggested that F. nucleatum is associated with poor patient prognosis in esophageal squamous cell carcinoma (ESCC). However, the mechanism by which F. nucleatum affects aggressive tumor behavior has yet to be elucidated. We have conducted this clinical, in vitro, and in vivo study to clarify the mechanism of ESCC progression induced by F. nucleatum. Transmission electron microscopy revealed that F. nucleatum invaded and occupied ESCC cells and impacted gene and protein expression. Comprehensive mRNA expression and pathway enrichment analyses of F. nucleatum-treated ESCC cells identified the "NF-κB" and "NOD-like receptor" signaling pathways as enriched. We confirmed the relationship between the presence of F. nucleatum and NF-κB activation in resected ESCC tissues. Furthermore, F. nucleatum-treated ESCC cells demonstrated enhanced growth ability, and NF-κB activation, as well as overexpression of NOD1 and phosphorylated RIPK2. Furthermore, treated cells showed accelerated tumor growth, with NF-κB activation in xenograft models. F. nucleatum invaded ESCC cells and induced the NF-κB pathway through the NOD1/RIPK2 pathway, leading to tumor progression.

Abstract
The objective of this single-center retrospective cohort study was to investigate the relationship between blood transfusion and persistent inflammation, immunosuppression, and catabolism syndrome (PIICS). The study was conducted at the Critical Care Center at Toho University Omori Medical Center, Japan. We included 391 patients in the PIICS group (hospitalization for > 15 days, C-reactive protein > 3.0 mg/dL or albumin < 3.0 mg/dL or lymph < 800/μL on day 14) and 762 patients in the non-PIICS group (hospitalization for > 15 days and not meeting the PIICS criteria). We performed univariate and multivariate logistic regression analyses using PIICS as the objective variable and red blood cell (RBC) or fresh frozen plasma or platelet (PLT) transfusion and other confounding factors as explanatory variables. In addition, we conducted a sensitivity analysis using propensity score matching analysis. The multivariate and propensity score analyses showed that RBC and PLT transfusions were significantly associated with PIICS. This is the first study to report an association between RBC and PLT transfusions and PIICS. Our findings have contributed to better understanding the risk factors of PIICS and suggest that physicians should consider the risk of PIICS occurrence when administering blood transfusions in intensive care unit (ICU) patients.

Increased Rate of Serum Prealbumin Level after Preoperative Enteral Nutrition as an Indicator of Morbidity in Gastrectomy for Gastric Cancer with Outlet Obstruction. World J Surg 2022; 46:624-630. [PMID: 34988604 DOI: 10.1007/s00268-021-06384-x] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/08/2021] [Indexed: 01/06/2023]
Abstract
BACKGROUND Preoperative malnutrition is believed to contribute to increased postoperative complications. Preoperative serum prealbumin level was reported to be a predictor of nutritional status and postoperative complications after gastrointestinal surgery, including gastrectomy. Gastric outlet obstruction caused by gastric cancer leads to insufficient nutritional status. However, the impact of preoperative enteral nutrition using naso-jejunal feeding tubes for patients with gastric outlet obstruction is not fully understood. METHODS From July 2010 to June 2020, 50 patients with gastric cancer-induced outlet obstruction who underwent gastrectomy following preoperative enteral nutrition via feeding tube were included. We investigated the relationship between changes in nutritional status after preoperative enteral nutrition and postoperative complications. Postoperative complications were defined as grade ≥II based on the Clavien-Dindo classification. RESULTS The median period of preoperative enteral nutrition was 10 days. The median increase rate of the serum prealbumin level was 10.5% (interquartile range, 0.63-38.2%), and patients with an increase rate ≥ 10% were defined as the elevated group. Postoperative morbidity was significantly higher in the non-elevated group (P = 0.0031). Univariate and multivariate analyses showed that an increased rate of the serum prealbumin level was an independent risk factor of postoperative complications for patients with gastric outlet obstruction caused by gastric cancer (P = 0.0025 and P = 0.009, respectively). CONCLUSIONS Preoperative enteral nutrition improved the serum prealbumin level of patients with gastric cancer-induced outlet obstruction, and an increased rate of prealbumin can be an indicator of sufficient preoperative enteral nutrition and decreased postoperative morbidity.

Abstract
AIM Digestive reconstruction after pharyngolaryngectomy with total esophagectomy (PLTE) remains challenging, with the optimal method remaining unclear. The current study aimed to clarify the short-term outcomes after PLTE and determine the optimal digestive reconstruction method. METHODS Based on a nationwide survey of 151 patients who underwent PLTE, outcomes of digestive reconstruction methods are described. RESULTS Among digestive reconstruction methods, a simple gastric tube was most frequently used (37.1%), followed by gastric tube combined with free graft transfer (FGT) (35.1%), gastric tube with microvascular anastomosis (22.5%), and other procedures (5.3%). Intraoperative evaluation of microcirculation (IOEM) was utilized in 29 patients (19.2%). Among the included patients, 66.9% developed any-grade complications, 41.0% developed severe complications, and 23.8% developed digestive reconstruction-related complications (DRRCs; leakage or necrosis). Reoperation within 30 days for any complications and DRRCs was required in 13.9% and 8.6% of the patients, respectively. Mortality within 90 days was observed in 4.6%. Among the three major methods, gastric tube combined with FGT promoted the least DRRCs in the gastric tube (P = .005), although the overall incidence of DRRCs was comparable. The use of IOEM was significantly associated with a reduction of severe DRRCs (P = .005). CONCLUSIONS Pharyngolaryngectomy with total esophagectomy is a high-risk surgery significantly associated with the occurrence of postoperative morbidity and mortality. Nonetheless, the addition of FGT can help prevent gastric tip complications, while IOEM can be an effective method for improving outcomes.

Abstract
BACKGROUND The registration committee for esophageal cancer in the Japan Esophageal Society (JES) has collected the patients' characteristics, treatment, and outcomes annually. METHODS We analyzed the data of patients who had visited the participating hospitals in 2014. We collected the data with a web-based data collection system using the National Clinical Database. We used the Japanese Classification of Esophageal Cancer 10th edition by JES and the TNM classification 7th edition by the Union of International Cancer Control (UICC) for cancer staging. RESULTS A total of 9026 cases were registered from 344 institutions in Japan. Squamous cell carcinoma and adenocarcinoma accounted for 87.9% and 7.1%, respectively. The 5-year survival rates of patients treated using endoscopic resection, concurrent chemoradiotherapy, radiotherapy alone, and esophagectomy were 87.1%, 33.7%, 25.3%, and 59.3%, respectively. Esophagectomy was performed in 5204 cases. Concerning the approach used for esophagectomy, 48.1% of the cases were treated thoracoscopically. The operative mortality (within 30 days after surgery) was 0.75%, and the hospital mortality was 2.0%. The survival curves showed an excellent discriminatory ability both in the clinical and pathologic stages by the JES system. The survival of pStage IV was better than IIIC in the UICC system, because pStage IV included the patients with supraclavicular lymph-node metastasis (M1 LYM). CONCLUSION We hope that this report contributes to improving all aspects of diagnosing and treating esophageal cancer in Japan.

Abstract
The first measurements of differential branching fractions of inclusive semileptonic B→X_{u}ℓ^{+}ν_{ℓ} decays are performed using the full Belle data set of 711 fb^{-1} of integrated luminosity at the ϒ(4S) resonance and for ℓ=e, μ. With the availability of these measurements, new avenues for future shape-function model-independent determinations of the Cabibbo-Kobayashi-Maskawa matrix element |V_{ub}| can be pursued to gain new insights in the existing tension with respect to exclusive determinations. The differential branching fractions are reported as a function of the lepton energy, the four-momentum-transfer squared, light-cone momenta, the hadronic mass, and the hadronic mass squared. They are obtained by subtracting the backgrounds from semileptonic B→X_{c}ℓ^{+}ν_{ℓ} decays and other processes, and corrected for resolution and acceptance effects.

Abstract
BACKGROUND/AIM Treatments containing ipilimumab have shown a good outcome in patients with non-small cell lung cancer (NSCLC) regardless of the PD-L1 tumor proportion score (TPS). However, the association between PD-L1 TPS and the expression of CTLA-4 in tumor-infiltrating lymphocytes is unknown. PATIENTS AND METHODS Fifty-five NSCLC patients who underwent surgery in our hospital were included in this study. We measured the proportions of CTLA-4+ regulatory T cells, and CTLA-4+ CD8 T cells, and statistically analyzed their correlations with the PD-L1 TPS. RESULTS Statistical correlations were found neither between the proportion of CTLA-4+ regulatory T cells to CD8 T cells and the PD-L1 TPS (p=0.2859) nor between the proportion of CTLA-4+ cells in CD8 T cells and the PD-L1 TPS (p=0.1919). CONCLUSION The proportions of CTLA-4+ regulatory T cells to CD8 T cells and CTLA-4+ cells in CD8 T cells were irrelevant to the PD-L1 TPS in NSCLC patients.

Abstract
Robot-assisted minimally invasive esophagectomy (RAMIE) for esophageal cancer has been performed increasingly frequently over the last few years. Robotic systems with articulated devices and tremor filtration allow surgeons to perform such procedures more meticulously than by hand. The feasibility of RAMIE has been demonstrated in several retrospective comparative studies, which showed similar short-term outcomes to conventional minimally invasive esophagectomy (cMIE). Considering the number of harvested lymph nodes, RAMIE may be superior to cMIE in terms of left upper mediastinal lymph node dissection. However, whether or not the addition of a robotic system to cMIE can help improve perioperative and oncological outcomes remains unclear. Given the lack of established evidence from randomized controlled trials, we must await the results of ongoing studies to reach any meaningful conclusions. Further advancements in robotic platforms, as well as the reduction in medical expenses, will be essential to demonstrate the real benefit of RAMIE.

Abstract
We report a measurement of the D^{0} and D^{+} lifetimes using D^{0}→K^{-}π^{+} and D^{+}→K^{-}π^{+}π^{+} decays reconstructed in e^{+}e^{-}→cc[over ¯] data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy e^{+}e^{-} collider. The data, collected at center-of-mass energies at or near the ϒ(4S) resonance, correspond to an integrated luminosity of 72 fb^{-1}. The results, τ(D^{0})=410.5±1.1(stat)±0.8(syst) fs and τ(D^{+})=1030.4±4.7(stat)±3.1(syst) fs, are the most precise to date and are consistent with previous determinations.

PD-L1 and PD-L2 expression status in relation to chemotherapy in primary and metastatic esophageal squamous cell carcinoma. Cancer Sci 2021; 113:399-410. [PMID: 34773342 PMCID: PMC8819296 DOI: 10.1111/cas.15198] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 10/11/2021] [Accepted: 10/21/2021] [Indexed: 02/06/2023] Open
Abstract
Immune checkpoint inhibitors have shown efficacy in various cancers. Although programmed death ligand 1/2 (PD‐L1/L2) expressions have been demonstrated as predictive biomarkers of response to immune checkpoint inhibitors and prognostic markers, whether PD‐L1/L2 expression is altered in esophageal squamous cell carcinoma during the therapeutic course is unclear. Whether PD‐L1/L2 expression in metastatic or recurrent lesions is consistent with that in primary tumors is also unknown. This study included 561 surgically resected esophageal squamous cell carcinomas and PD‐L1/L2 expression was evaluated by immunohistochemistry. We investigated the influence of chemotherapeutic drugs (cisplatin and fluorouracil) on PD‐L1/L2 expression and PD‐L1/L2‐related pathways in vitro. We also examined PD‐L1/L2 expression in 18 surgically resected lymph node metastases and 10 recurrent lesions compared with primary lesions. The positive rate of PD‐L1 was significantly higher in patients with preoperative chemotherapy than in those without preoperative therapy. The positive rate of PD‐L2 expression showed no significant difference between patient groups. Cisplatin increased PD‐L1 expression in cancer cell lines in vitro, but decreased PD‐L2 in some cell lines. The effects of cisplatin on phosphorylated signal transducer and activator of transcription 1/3 (pSTAT1/3) also differed depending on cell lines. Fluorouracil increased PD‐L1 and PD‐L2 expression. PD‐L1/L2 expression in lymph node metastases and recurrent lesions did not always match expression in primary lesions. PD‐L1/L2 expression may be altered by preoperative chemotherapy, and PD‐L1 /L2 expression in primary lesions does not always match that of metastatic/recurrent lesions. Thus, one‐time evaluation is not sufficient to evaluate PD‐L1/L2 expression as a biomarker in esophageal cancer.

Penetrating vertebral artery injury treated by combining the "zone" approach and imaging tests: A case report. Clin Case Rep 2021; 9:e05134. [PMID: 34849232 PMCID: PMC8609188 DOI: 10.1002/ccr3.5134] [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: 07/03/2021] [Revised: 11/08/2021] [Accepted: 11/09/2021] [Indexed: 11/18/2022] Open
Abstract
Patients with vertebral artery injury from penetrating neck trauma may not present with signs of vascular injury because of anatomical characteristics and concomitant conditions, such as hypothermia and shock. If patients are hemodynamically stable, imaging tests should be performed to examine the posterior components, including the vertebral artery.
