Abstract
BACKGROUND Periodontitis is a biofilm-associated inflammatory periodontal disease associated with postoperative complications after esophagectomy. However, few studies have evaluated the inflammatory burden posed by periodontitis quantitively for patients undergoing oncologic esophagectomy. This study aimed to clarify the relationship between periodontitis and postoperative pneumonia using periodontal inflammatory surface area (PISA). METHODS The study analyzed 251 patients who underwent esophagectomy for esophageal cancer. The patients were classified into low-PISA and high-PISA groups according to preoperative PISA, and the relationship between the occurrence and severity of postoperative pneumonia was investigated. RESULTS The high-PISA group (n = 69) included more males (P < 0.001) and patients with poor performance status (P < 0.024). Postoperative pneumonia occurred more frequently in the high-PISA group than in the low-PISA group (31.9 % vs. 15.9 %; P = 0.008), whereas the incidences of other complications did not differ significantly. In addition, the incidence of severe pneumonia was significantly higher in the high-PISA group (7.2 % vs. 1.6 %; P = 0.038). In the multivariable analysis for adjustment of preoperative confounders, age older than 70 years (odds ratio [OR], 2.62; P = 0.006), high PISA (OR, 2.45; P = 0.012), and smoking history (OR, 2.78; P = 0.006) were the independent variables predicting postoperative pneumonia. CONCLUSION Preoperative higher PISA was significantly associated with the occurrence of overall and severe postoperative pneumonia. The quantitative evaluation of periodontitis using PISA is a useful measure for predicting postoperative pneumonia, and intensive periodontal intervention may contribute to decreasing postoperative pneumonia.

Abstract
BACKGROUND Diabetes mellitus (DM) is known to be a risk factor for postoperative infectious complications (PICs). However, the significance of postoperative hyperglycemia in non-DM cases has not been well investigated. We sought to establish whether postoperative hyperglycemia is associated with PICs and survival among patients with esophageal cancer, with a focus on non-DM cases. METHODS A total of 430 patients who underwent subtotal esophagectomy for esophageal cancer between 2014 and 2018 were enrolled. Postoperative blood glucose was measured by arterial blood gas test every 8 h from postoperative day (POD) 1 to POD4. The association between hyperglycemia (mean ≥ 200 mg/dl) and PICs or long-term outcomes on each POD was investigated. RESULTS There were 53 DM and 377 non-DM cases. PICs occurred in 127 patients. In the multivariate analysis of all cases, PICs were associated with hyperglycemia on POD1 or -2 (odds ratio [OR] = 1.69, 95% CI, 1.05-2.73, P = 0.031 for POD1; OR = 2.55, 95% CI, 1.10-5.93, P = 0.029 for POD 2). Among non-DM cases, the association was more evident, and persisted until POD4 (OR = 1.94, 95% CI, 1.16-3.24, P = 0.012 for POD1; OR = 3.68, 95% CI, 1.28-10.6, P = 0.016 for POD2; OR = 3.07, 95% CI, 1.11-8.51, P = 0.031 for POD4). Survival analyses limited to R0 cases revealed hyperglycemia on POD2 as an independent prognostic factor in all cases (N = 412) [hazard ratio (HR) = 2.61, 95%CI, 1.21-5.63, P = 0.014], with the prognostic impact more evident among non-DM cases (N = 360) (HR = 4.38, 95% CI, 1.82-10.57, P = 0.0010). CONCLUSION Postoperative hyperglycemia is associated with PICs and worse survival after esophagectomy, particularly in patients without DM.

Abstract
Introduction Osteoarthritis (OA) is the most common form of arthritis. OA results from the breakdown of cartilage, which leads to deterioration of the entire joint and the connective tissue that holds the joint together, and gradually and irreversibly worsens over time. Adipose-derived stem/stromal cells (ADSCs) have been used in the treatment of knee OA. However, the safety and efficacy of ADSC treatment of OA remain unclear. In this study, we investigated the pathophysiology of severe knee arthritis that occurred after ADSC treatment by screening for autoantibodies in synovial fluid from patients who received ADSC treatment. Methods Adult Japanese patients with OA who received ADSC treatment at Saitama Cooperative Hospital between June 2018 and October 2021 were enrolled. Antibodies (Abs) were screened using immunoprecipitation (IPP) with [35S]-methionine-labeled HeLa cell extracts. The detected protein was identified by liquid chromatography coupled with time-of-flight mass spectrometry (MS) and ion trap MS, and the corresponding proteins were confirmed as autoantigens using immunoblotting. Ab titers were measured using an enzyme-linked immunosorbent assay. Results A total of 113 patients received ADSC treatment, and 75% (85/113) received ADSC injection at least twice with a 6-month interval between. No obvious abnormalities were observed in any patient after their first treatment; by contrast, 53% (45/85) of patients who received their second or third ADSC injection showed severe knee arthritis. IPP detected a common anti-15 kDa Ab in synovial fluid of 62% (8/13) of the samples analyzed from patients who showed severe arthritis. This Ab was not detected in synovial fluid obtained from the same joints before treatment. The corresponding autoantigen was identified as histone H2B. All available synovial samples from patients who tested positive for anti-histone H2B Ab were newly positive after the treatment; that is, none had been positive for anti-histone H2B Ab before treatment. Conclusions Multiple ADSC injections for OA induced severe arthritis in a high percentage of patients, particularly after the second injection. Synovial fluid from some patients with knee arthritis contained Ab to histone H2B that appeared only after ADSC treatment. These findings provide new insights into the pathogenesis of ADSC treatment-induced severe arthritis.

Abstract
We present the first comprehensive tests of the universality of the light leptons in the angular distributions of semileptonic B^{0}-meson decays to charged spin-1 charmed mesons. We measure five angular-asymmetry observables as functions of the decay recoil that are sensitive to lepton-universality-violating contributions. We use events where one neutral B is fully reconstructed in ϒ(4S)→BB[over ¯] decays in data corresponding to 189 fb^{-1} integrated luminosity from electron-positron collisions collected with the Belle II detector. We find no significant deviation from the standard model expectations.

Abstract
BACKGROUND Detecting pathological complete response (pCR) before surgery would facilitate nonsurgical approach after neoadjuvant chemotherapy (NAC). We developed an artificial intelligence (AI)-guided pCR evaluation using a deep neural network to identify pCR before surgery. METHODS This study examined resectable esophageal squamous cell carcinoma (ESCC) patients who underwent esophagectomy after NAC. The same number of histological responders without pCR and non-responders were randomly selected based on the number of pCR patients. Endoscopic images were analyzed using a deep neural network. A test dataset consisting of 20 photos was used for validation. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of AI and four experienced endoscopists' pCR evaluations were calculated. For pathological response evaluation, Japanese Classification of Esophageal Cancer was used. RESULTS The study enrolled 123 patients, including 41 patients with pCR, the same number of histological responders without pCR, and non-responders [grade 0, 5 (4%); grade 1a, 36 (30%); grade 1b, 21 (17%); grade 2, 20 (16%); grade 3, 41 (33%)]. In 20 models, the median values of sensitivity, specificity, PPV, NPV, and accuracy for endoscopic response (ER) detection were 60%, 81%, 77%, 67%, and 70%, respectively. Similarly, the endoscopists' median of these was 43%, 90%, 85%, 65%, and 66%, respectively. CONCLUSIONS This proof-of-concept study demonstrated that the AI-guided endoscopic response evaluation after NAC could identify pCR with moderate accuracy. The current AI algorithm might guide an individualized treatment strategy including nonsurgical approach in ESCC patients through prospective studies with careful external validation to demonstrate the clinical value of this diagnostic approach including primary tumor and lymph node.

Abstract
We measure the lifetime of the D_{s}^{+} meson using a data sample of 207 fb^{-1} collected by the Belle II experiment running at the SuperKEKB asymmetric-energy e^{+}e^{-} collider. The lifetime is determined by fitting the decay-time distribution of a sample of 116×10^{3} D_{s}^{+}→ϕπ^{+} decays. Our result is τ_{D_{s}^{+}}=(499.5±1.7±0.9) fs, where the first uncertainty is statistical and the second is systematic. This result is significantly more precise than previous measurements.

Abstract
The progression of precancerous lesions to malignancy is often accompanied by increasing complexity of chromosomal alterations but how these alterations arise is poorly understood. Here we perform haplotype-specific analysis of chromosomal copy-number evolution in the progression of Barrett's esophagus (BE) to esophageal adenocarcinoma (EAC) on multiregional whole-genome sequencing data of BE with dysplasia and microscopic EAC foci. We identify distinct patterns of copy-number evolution indicating multigenerational chromosomal instability that is initiated by cell division errors but propagated only after p53 loss. While abnormal mitosis, including whole-genome duplication, underlies chromosomal copy-number changes, segmental alterations display signatures of successive breakage-fusion-bridge cycles and chromothripsis of unstable dicentric chromosomes. Our analysis elucidates how multigenerational chromosomal instability generates copy-number variation in BE cells, precipitates complex alterations including DNA amplifications, and promotes their independent clonal expansion and transformation. In particular, we suggest sloping copy-number variation as a signature of ongoing chromosomal instability that precedes copy-number complexity. These findings suggest copy-number heterogeneity in advanced cancers originates from chromosomal instability in precancerous cells and such instability may be identified from the presence of sloping copy-number variation in bulk sequencing data.

Primary ovarian insufficiency associated with lenvatinib therapy in a patient with hepatocellular carcinoma: A case report. Oncol Lett 2023; 26:450.

Abstract
The therapeutic effects of molecular targeted drugs are, in some cases, more pronounced than those of conventional chemotherapy, and their introduction as a standard treatment is increasing. The present report describes a case of ovarian insufficiency in a young woman caused by tyrosine kinase inhibitor lenvatinib. The 25-year-old woman received lenvatinib (8 mg/day) for 98 days as preoperative chemotherapy for hepatocellular carcinoma. Blood testing the day before starting lenvatinib administration indicated 4.40 mIU/ml luteinizing hormone (LH), 5.2 mIU/ml follicle-stimulating hormone (FSH) and age-equivalent hormone values. Amenorrhea occurred after the start of administration, and 48 days later, the LH level was 41.8 mIU/ml and the FSH level was 44 mIU/ml, indicating a decrease in ovarian function. The patient underwent hepatectomy, and 49 days after the end of lenvatinib administration, the LH level had improved to 4.5 mIU/ml and the FSH level had improved to 2.5 mIU/ml. After the hepatectomy, the patient began to have regular menstrual cycles once again. Ovarian toxicity has not been recognized as a side effect of lenvatinib. However, the present report describes primary ovarian insufficiency considered to be caused by this drug. Potential damage to ovarian function may need to be considered when molecular targeted drugs with the same mechanism of action as lenvatinib are used in young women.

Abstract
BACKGROUND Oncologic esophagectomy in patients with a history of total pharyngolaryngectomy (TPL) is challenging. There are two different esophagectomy procedures: total esophagectomy with cervical anastomosis (McKeown) and subtotal esophagectomy with intrathoracic anastomosis (Ivor-Lewis). Differences in outcomes between McKeown and Ivor-Lewis esophagectomies for patients with this history remain unclear. METHODS We retrospectively reviewed 36 patients with a history of TPL who underwent oncologic esophagectomy and compared the clinical outcomes between the procedures. RESULTS Twelve (33.3%) and 24 (66.7%) patients underwent McKeown and Ivor-Lewis esophagectomies, respectively. McKeown esophagectomy was more frequently performed for the supracarinal tumors (P = 0.002). Other baseline characteristics, including the history of radiation therapy, were comparable between the groups. Postoperatively, the incidences of pneumonia and anastomotic leakage were higher in the McKeown group than in the Ivor-Lewis group (P = 0.029 and P < 0.001, respectively). Neither tracheal necrosis nor remnant esophageal necrosis was observed. The overall and recurrence-free survival rates were comparable between the groups (P = 0.494 and P = 0.813, respectively). CONCLUSIONS When performing esophagectomy for patients with a history of TPL, if it is oncologically acceptable and technically available, Ivor-Lewis is preferable over McKeown esophagectomy for avoiding postoperative complications.

Abstract
We report the first search for a nonstandard-model resonance decaying into τ pairs in e^{+}e^{-}→μ^{+}μ^{-}τ^{+}τ^{-} events in the 3.6-10 GeV/c^{2} mass range. We use a 62.8 fb^{-1} sample of e^{+}e^{-} collisions collected at a center-of-mass energy of 10.58 GeV by the Belle II experiment at the SuperKEKB collider. The analysis probes three different models predicting a spin-1 particle coupling only to the heavier lepton families, a Higgs-like spin-0 particle that couples preferentially to charged leptons (leptophilic scalar), and an axionlike particle, respectively. We observe no evidence for a signal and set exclusion limits at 90% confidence level on the product of cross section and branching fraction into τ pairs, ranging from 0.7 to 24 fb, and on the couplings of these processes. We obtain world-leading constraints on the couplings for the leptophilic scalar model for masses above 6.5 GeV/c^{2} and for the axionlike particle model over the entire mass range.

Abstract
Upon nuclear waste canister failure and contact of spent nuclear fuel with groundwater, the UO2 matrix of spent fuel will interact with oxidants in the groundwater generated by water radiolysis. Bicarbonate (HCO3-) is often found in groundwater, and the H2O2 induced oxidative dissolution of UO2 in bicarbonate solution has previously been studied under various conditions. Temperatures in the repository at the time of canister failure will differ depending on the location, yet the effect of temperature on oxidative dissolution is unknown. To investigate, the decomposition rate of H2O2 at the UO2 surface and dissolution of UVI in bicarbonate solution (0.1, 1, 10 and 50 mM) was analysed at various temperatures (10, 25, 45 and 60 °C). At [HCO3-] ≥ 1 mM, the concentration of dissolved UVI decreased with increasing temperature. This was attributed to the formation of UVI-bicarbonate species at the surface and a change in the mechanism of H2O2 decomposition from oxidative to catalytic. At 0.1 mM, no obvious correlation between temperature and U dissolution was observed, and thermodynamic calculations indicated this was due to a change in the surface species. A pathway to explain the observed dissolution behaviour of UO2 in bicarbonate solution as a function of temperature was proposed.

Abstract
We report a measurement of the CP-violating parameters C and S in B^{0}→K_{S}^{0}π^{0} decays at Belle II using a sample of 387×10^{6} BB[over ¯] events recorded in e^{+}e^{-} collisions at a center-of-mass energy corresponding to the ϒ(4S) resonance. These parameters are determined by fitting the proper decay-time distribution of a sample of 415 signal events. We obtain C=-0.04_{-0.15}^{+0.14}±0.05 and S=0.75_{-0.23}^{+0.20}±0.04, where the first uncertainties are statistical and the second are systematic.

Abstract
We successfully performed electron scattering off unstable nuclei which were produced online from the photofission of uranium. The target ^{137}Cs ions were trapped with a new target-forming technique that makes a high-density stationary target from a small number of ions by confining them in an electron storage ring. After developments of target generation and transportation systems and the beam stacking method to increase the ion beam intensity up to approximately 2×10^{7} ions per pulse beam, an average luminosity of 0.9×10^{26} cm^{-2} s^{-1} was achieved for ^{137}Cs. The obtained angular distribution of elastically scattered electrons is consistent with a calculation. This success marks the realization of the anticipated femtoscope which clarifies the structures of exotic and short-lived unstable nuclei.

Abstract
BACKGROUND Although neoadjuvant treatment has become the standard of care for patients with locally advanced esophageal cancer, previous studies comparing neoadjuvant chemotherapy (NAC) and neoadjuvant chemoradiotherapy (NACRT) have demonstrated inconclusive results. METHODS Our study cohort included 3978 patients from 85 institutions. Those who underwent NAC or NACRT followed by surgery for esophageal squamous cell carcinoma (ESCC) were eligible for inclusion. We used the inverse probability of treatment weighting (IPTW) method to compare the outcomes between NAC and NACRT. RESULTS Among the 3978 patients, 3777 (94.9%) received NAC and 201 (5.1%) received NACRT. After IPTW adjustment, the NACRT group had more patients with pathologically downstaged diseases and significantly better pathological response compared with the NAC group (p < 0.001); however, 5-year overall survival (OS), recurrence-free survival (RFS), and regional recurrence-specific survival (RRSS) were comparable between the groups. Subgroup analysis stratifying patients according to cT category showed that among cT1-2 patients, those in the NACRT group had significantly longer 5-year OS, RFS, and RRSS than those in the NAC group (P = 0.024, < 0.001, and 0.020, respectively). In contrast, no significant differences were observed among cT3-4a patients. The competing risks regression model showed comparable subdistribution hazard ratios for 10-year cancerous and noncancerous deaths between the NAC and NACRT groups. CONCLUSIONS Compared with NAC, NACRT for ESCC did not promote better survival despite better therapeutic effects and did not increase noncancerous deaths.

Robotic-assisted minimally invasive esophagectomy (RAMIE) has been rapidly spreading worldwide as a novel minimally invasive approach for esophageal cancer. This narrative review aimed to elucidate the current situation and future perspectives of RAMIE for esophageal cancer. References were searched using PubMed and Embase for studies published up to 8 April 2023. Search terms included "esophagectomy" or "esophageal cancer" and "robot" or "robotic" or "robotic-assisted." There are several different uses for the robot in esophagectomy. Overall complications are equivalent or may be less in RAMIE than in open esophagectomy and conventional (thoracoscopic) minimally invasive esophagectomy. Several meta-analyses demonstrated the possibility of RAMIE in reducing pulmonary complications, although the equivalent incidence was observed in two randomized controlled trials. RAMIE may increase the number of dissected lymph nodes, especially in the left recurrent laryngeal nerve area. Long-term outcomes are comparable between the procedures, although further research is required. Further progress in robotic technology combined with artificial intelligence is expected.

Test of Light-Lepton Universality in the Rates of Inclusive Semileptonic B-Meson Decays at Belle II. PHYSICAL REVIEW LETTERS 2023; 131:051804. [PMID: 37595249 DOI: 10.1103/physrevlett.131.051804] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/25/2023] [Revised: 05/03/2023] [Accepted: 05/11/2023] [Indexed: 08/20/2023]
Abstract
We present the first measurement of the ratio of branching fractions of inclusive semileptonic B-meson decays, R(X_{e/μ})=B(B→Xeν)/B(B→Xμν), a precision test of electron-muon universality, using data corresponding to 189 fb^{-1} from electron-positron collisions collected with the Belle II detector. In events where the partner B meson is fully reconstructed, we use fits to the lepton momentum spectra above 1.3 GeV/c to obtain R(X_{e/μ})=1.007±0.009(stat)±0.019(syst), which is the most precise lepton-universality test of its kind and agrees with the standard-model expectation.

Real-world Evaluation of the Efficacy of Neoadjuvant DCF Over CF in Esophageal Squamous Cell Carcinoma: Propensity Score-matched Analysis From 85 Authorized Institutes for Esophageal Cancer in Japan. Ann Surg 2023; 278:e35-e42.

Abstract
OBJECTIVE We aimed to evaluate the efficacy of neoadjuvant docetaxel, cisplatin, and 5-fluorouracil (DCF) therapy over cisplatin and 5-fluorouracil (CF) in patients with surgically resectable advanced esophageal squamous cell carcinoma (ESCC), using real-world data from 85 esophageal centers. BACKGROUND JCOG1109 trial, which assessed the superiority of DCF over CF, and the superiority of chemoradiotherapy with CF over CF alone demonstrated the significant survival advantage of neoadjuvant DCF in overall survival (OS) over CF for ESCC. METHODS The ESCC patients who received neoadjuvant CF or DCF at 85 Japanese esophageal centers certified by the Japan Esophageal Society were retrospectively reviewed. After propensity score (PS) matching, the OS and recurrence-free survival were compared between CF and DCF. RESULTS We initially enrolled 4781 patients. After data cleaning and PS matching using pretreatment variables, 1074 patients for each group were selected for subsequent analysis. There was no significant difference in the incidence of postoperative pneumonia and anastomotic leakage. In the survival analysis, OS was significantly longer in DCF group than CF group (hazard ratio, 0.868; 95% confidence interval, 0.770-0.978; P =0.02), as well as recurrence-free survival (hazard ratio, 0.850; 95% confidence interval, 0.761-0.949; P =0.004). The survival advantage of DCF was not observed in patients with 76 years old or older. CONCLUSIONS Neoadjuvant DCF therapy showed a remarkable survival advantage in surgically resectable ESCC patients, especially in patients who were 75 years old or younger. The current real-world evidence will encourage recommendations for DCF as a standard regimen in neoadjuvant chemotherapy-based treatment strategy for ESCC.

Prognostic significance of circulating basophil counts in patients who underwent esophagectomy for esophageal cancer. Langenbecks Arch Surg 2023; 408:235.

Abstract
PURPOSE Recent reports have suggested that basophils influence allergic reactions and tumor immunity. In this study, we aimed to elucidate the association between preoperative circulating basophil (CB) counts and the outcomes of patients who underwent esophagectomy for esophageal cancer. METHODS A total of 783 consecutive patients who underwent esophagectomy for esophageal cancer were eligible. The clinicopathological factors and prognoses were compared between the groups stratified by the preoperative counts of CB. RESULTS There were more advanced clinical T and N stages in the low CB group than in the high CB group (P = 0.01 and = 0.04, respectively). The incidences of postoperative complications were comparable between the groups. The low CB count was associated with unfavorable overall and recurrence-free survivals (P = 0.04 and 0.01, respectively). In the multivariate analysis, low CB count was one of the independent prognostic factors for poor recurrence-free survival (HR 1.33; 95% CI 1.04-1.70; P = 0.02). In addition, hematogenous recurrence occurred more frequently in the low CB group than in the high CB group (57.6% vs. 41.4%, P = 0.04). CONCLUSION A preoperative low CB count was an unfavorable prognosticator in patients who underwent esophagectomy for esophageal cancer.
