Abstract
Effective treatment for advanced lung cancer and idiopathic interstitial pneumonia (IIP) remains an unmet medical need. The relationship between chemotherapy's effectiveness in advanced lung cancer and the risk of acute exacerbation of IIP is poorly investigated. There is limited evidence that patients who experience an acute exacerbation of IIPs during cytotoxic chemotherapy have poorer outcomes than those who do not. Among 1004 patients with advanced lung cancer and IIPs enrolled in our published multi-centre retrospective study from 110 Japanese institutions, 708 patients (male: female, 645:63; mean age, 70.4) received first-line chemotherapy. The occurrence of chemotherapy-triggered acute exacerbations of IIPs and overall survival (OS) were analysed. The OS between groups of patients with and without the occurrence of acute exacerbation was compared at four landmark time points (30, 60, 90, and 120 days), starting from the first-line chemotherapy, using the landmark method. The incidence of acute exacerbation in patients who received first-line chemotherapy with small cell lung cancer (SCLC) and non-small cell lung cancer (NSCLC) was more frequent in NSCLC patients than in SCLC (4.2% vs 12.6%; odds ratio [OR]: 3.316; 95% confidence interval [CI] 1.25-8.8). Median survival time was 9.9 months (95% CI 9.2-10.7). Patients who experienced acute exacerbation had significant worse survival outcomes than those who did not at various time points (30 days, hazard ratio [HR]: 5.191, 95% CI 2.889-9.328; 60 days, HR: 2.351, 95% CI 1.104-5.009; 90 days, HR: 2.416, 95% CI 1.232-4.739; and 120 days, HR: 2.521, 95% CI 1.357-4.681). Acute exacerbation during first-line chemotherapy can predict poor survival.Trial Registration number: UMIN000018227.

Abstract
Idiopathic pulmonary fibrosis (IPF) is an interstitial lung disease with a poor prognosis and an unknown cause that generally progresses to pulmonary fibrosis and leads to irreversible tissue alteration. The "Guidelines for the treatment of idiopathic pulmonary fibrosis 2017," specializing in the treatment of IPF for the first time in Japan and presenting evidence-based standard treatment methods suited to the state of affairs in Japan, was published in 2017, in line with the 2014 version of "Formulation procedure for Minds Clinical Practice Guidelines." Because new evidence had accumulated, we formulated the "Guidelines for the treatment of Idiopathic Pulmonary Fibrosis 2023 (revised 2nd edition)." While keeping the revision consistent with the ATS/ERS/JRS/ALAT IPF treatment guidelines, new clinical questions (CQs) on pulmonary hypertension were added to the chronic stage, in addition to acute exacerbation and comorbid lung cancer, which greatly affect the prognosis but are not described in the ATS/ERS/JRS/ALAT IPF guidelines. Regarding the advanced stages, we additionally created expert consensus-based advice for palliative care and lung transplantation. The number of CQs increased from 17 in the first edition to 24. It is important that these guidelines be used not only by respiratory specialists but also by general practitioners, patients, and their families; therefore, we plan to revise them appropriately in line with ever-advancing medical progress.

Abstract
A common goal of the dairy industry is to shorten the calving interval to reap several benefits associated with improved fertility. Early pregnancy detection is crucial to shorten this interval, allowing for prompt re-insemination of cows that failed to conceive after the first service. Currently, the industry lacks a method to accurately predict pregnancy within the first 3 wk. The polypeptide cytokine IFN-tau (IFNT) is the primary signal for maternal recognition of pregnancy in ruminants. As IFNT is released from the early conceptus, it initiates a cascade of effects, including upregulation of IFN-stimulated genes (ISG). Expression of ISG can be detected in the peripheral blood. The present study aimed to characterize peripheral transcriptomic changes, including the ISG, as early as d 7 after embryo transfer. A total of 170 Holstein heifers received in vitro-produced embryos. Whole blood was collected from these heifers within 24 h of the embryo transfer (d 0), d 7, and d 14 after embryo transfer. The heifers were divided into 2 groups, pregnant and nonpregnant, based on pregnancy diagnosis on d 28 via ultrasound. Total RNA was extracted from the peripheral blood of pregnant and nonpregnant heifers, pooled and sequenced. Expression analysis on d 7 heifers resulted in 13 significantly differentially expressed genes mostly related to innate immunity. Differential expression analysis comparing pregnant heifers on d 0 to the same heifers on d 14 showed 51 significantly differentially expressed genes. Eight genes were further quantified through reverse-transcription quantitative real-time PCR for biological validation. On d 7 after embryo transfer, mRNA transcriptions of EDN1, CXCL3, CCL4, and IL1A were significantly upregulated in pregnant heifers (n = 14) compared with nonpregnant heifers (n = 14), with respective fold changes of 8.10, 18.12, 29.60, and 29.97. Although on d 14 after embryo transfer, mRNA transcriptions of ISG15, MX2, OASY1, and IFI6 were significantly upregulated in the blood of pregnant heifers (n = 14) compared with the same heifers on d 0, with respective fold changes of 5.09, 2.59, 3.89, and 3.08. These findings demonstrate that several immune-related genes and ISG are activated during the first 2 wk after embryo transfer, which may explain how the maternal immune system accommodates the allogenic conceptus. To further investigate the diagnostic potentials of these genes, future studies are warranted to analyze the specificity and sensitivity of these biomarkers to predict early pregnancy.

Abstract
BACKGROUND AND OBJECTIVE Endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) is a diagnostic procedure with adequate performance; however, its ability to provide specimens of sufficient quality and quantity for treatment decision-making in advanced-stage lung cancer may be limited, primarily due to blood contamination. The use of a 0.96-mm miniforceps biopsy (MFB) permits true histological sampling, but the resulting small specimens are unsuitable for the intended applications. Therefore, we introduced a 1.9-mm standard-sized forceps biopsy (SFB) and compared its utility to that of MFB. METHODS We prospectively enrolled patients from three institutions who presented with hilar/mediastinal lymphadenopathy and suspected advanced-stage lung cancer, or those who were already diagnosed but required additional tissue specimens for biomarker analysis. Each patient underwent MFB followed by SFB three or four times through the tract created by TBNA using a 22-gauge needle on the same lymph node (LN). Two pathologists assessed the quality and size of each specimen using a virtual slide system, and diagnostic performance was compared between the MFB and SFB groups. RESULTS Among the 60 enrolled patients, 70.0% were diagnosed with adenocarcinoma. The most frequently targeted sites were the lower paratracheal LNs, followed by the interlobar LNs. The diagnostic yields of TBNA, MFB and SFB were 91.7%, 93.3% and 96.7%, respectively. The sampling rate of high-quality specimens was significantly higher in the SFB group. Moreover, the mean specimen size for SFB was three times larger than for MFB. CONCLUSION SFB is useful for obtaining sufficient qualitative and quantitative specimens.

Abstract
This study, for the first time, has investigated the relationships between alterations of mangiferin contents in mango leaves at different maturity stages and their antibacterial properties. Leaves were classified into six different maturity stages based on their color: (1) young dark reddish brown, (2) young yellow, (3) young light green, (4) mature green, (5) old dark green, and (6) old yellow leaves. Ethanol extracts were then examined against Gram-positive and Gram-negative bacteria, applying broth dilution and agar well diffusion methods. In addition, we also measured the mangiferin contents in leaves at different stages for the purpose of evaluating how the changes in this phytochemistry value affects their activities against bacteria. The results showed that extracts from leaves at young ages had better antibacterial properties than those from old leaves, as evidenced by the lower minimum inhibitory concentrations and larger inhibitory zones. In addition, we also found that the contents of mangiferin were significantly decreased followed the maturation process. These results suggest that mango leaves at young stages, especially dark reddish brown and young yellow leaves, are preferable for application in bacterial infections and other therapies related to mangiferin's constituents.

Abstract
BACKGROUND Occupational cholangiocarcinoma is associated with exposure to organic solvents, such as dichloromethane (DCM) and 1,2-dichloropropane (DCP). This report describes a case of occupational cholangiocarcinoma detected through regularly imaging following the discovery of elevated serum γ-glutamyl trans peptidase (γ-GTP) levels revealed during regular checkup. CASE PRESENTATION A 43-year-old man who had been working in a printing company with 15 years of exposure to organic solvents presented to our hospital owing to abnormalities found during a routine checkup. Ultrasound (US) imaging revealed thickening of the gallbladder wall accompanied by gallstones, although in the blood tests, γ-GTP levels were within normal range. Given the high risk of cholangiocarcinoma development, the patient underwent regular monitoring with abdominal US and blood tests at a local doctor's office. At the age of 48, his serum γ-GTP level mildly elevated for the first time, prompting the initiation of semi-annual magnetic resonance cholangiopancreatography (MRCP). By the age of 50 years, dilation in B8 was detected, and one and a half years later, a tumor on the central side of the B8 dilation appeared. The patient was diagnosed with intrahepatic cholangiocarcinoma, which was treated with anterior sectionectomy. Pathological examination revealed an adenocarcinoma with a papillary glandular ductal structure at the root of the B8. In addition, biliary intraepithelial neoplasia (BilIN) and dysplasia have been identified around the tumor and periphery bile ducts and in noncancerous bile ducts. Postoperatively, the patient received 6 months of adjuvant chemotherapy with S-1monotherapy. Eight months after surgery, the patient remained under observation with no signs of recurrence. CONCLUSIONS We report a case of occupational cholangiocarcinoma detected during a prolonged period of regular follow-up after exposure to DCM and DCP. Given the delayed carcinogenesis process, occupational cholangiocarcinomas manifest long after exposure to organic solvents, therefore, ongoing screening is extremely important. Vigilance is essential to avoid underdiagnosis, particularly for individuals who are at an increased risk of developing this form of cancer. Continuous monitoring is key to the early detection and effective management of occupational cholangiocarcinoma.

Abstract
BACKGROUND The increasing incidence of gastric cancer in the elderly underscores the need for an in-depth understanding of the challenges and risks associated with surgical interventions in this demographic. This study aims to investigate the risk factors and prognostic indicators for non-cancer-related mortality following curative surgery in elderly gastric cancer patients. METHODS This retrospective analysis examined 684 patients with pathological Stage I-III gastric cancer who underwent curative resection between January 2012 and December 2021. The study focused on patients aged 70 years and above, evaluating various clinical and pathological variables. Univariate analysis was utilized to identify potential risk factors with to non-cancer-related mortality and to access prognostic outcomes. RESULTS Out of the initial 684 patients, 244 elderly patients were included in the analysis, with 33 succumbing to non-cancer-related causes. Univariate analysis identified advanced age (≥ 80 years), low body mass index (BMI) (< 18.5), high Charlson Comorbidity Index (CCI), and the presence of overall surgical complications as significant potential risk factors for non-cancer related mortality. These factors also correlated with poorer overall survival and prognosis. The most common cause of non-cancer-related deaths were respiratory issues and heart failure. CONCLUSION In elderly gastric cancer patients, managing advanced age, low BMI, high CCI, and minimizing postoperative complications are essential for reducing non-cancer-related mortality following curative surgery.

Abstract
Hepatocellular carcinoma (HCC) has a high rate of recurrence and poor prognosis, even after curative surgery. Multikinase inhibitors have been applied for HCC patients, but their effect has been restricted. This study aims to clarify the clinical impact of SUV420H1/KMT5B, one of the methyltransferases for histone H4 at lysine 20, and elucidate the novel mechanisms of HCC progression. We retrospectively investigated SUV420H1 expression using HCC clinical tissue samples employing immunohistochemical analysis (n = 350). We then performed loss-of-function analysis of SUV420H1 with cell cycle analysis, migration assay, invasion assay and RNA sequence for Gene Ontology (GO) pathway analysis in vitro, and animal experiments with xenograft mice in vivo. The SUV420H1-high-score group (n = 154) had significantly poorer prognosis for both 5-year overall and 2-year/5-year disease-free survival than the SUV420H1-low-score group (n = 196) (p < 0.001 and p < 0.05, respectively). The SUV420H1-high-score group had pathologically larger tumor size, more tumors, poorer differentiation, and more positive vascular invasion than the SUV420H1-low-score group. Multivariate analysis demonstrated that SUV420H1 high score was the poorest independent factor for overall survival. SUV420H1 knockdown could suppress cell cycle from G1 to S phase and cell invasion. GO pathway analysis showed that SUV420H1 contributed to cell proliferation, cell invasion, and/or metastasis. Overexpression of SUV420H1 clinically contributed to poor prognosis in HCC, and the inhibition of SUV420H1 could repress tumor progression and invasion both in vitro and in vivo; thus, further analyses of SUV420H1 are necessary for the discovery of future molecularly targeted drugs.

Abstract
OBJECTIVE Percutaneous transhepatic gallbladder aspiration (PTGBA) and/or drainage (PTGBD) are useful approaches in the management of acute cholecystitis in patients who cannot tolerate surgery because of poor general condition or severe inflammation. However, reports regarding its effect on the surgical outcomes of subsequent laparoscopic cholecystectomy (LC) are sparse. The aim of this retrospective study was to investigate the influence of PTGBA on surgical outcomes of subsequent LC by comparing the only-PTGBA group, including patients who did not need the additional-PTGBD, versus the additional-PTGBD group, including those who needed the additional-PTGBD after PTGBA. PATIENTS AND METHODS We conducted a post hoc analysis of our multi-institutional data. This study included 63 patients who underwent LC after PTGBA, and we compared the surgical outcomes between the only-PTGBA group (n = 56) and the additional-PTGBD group (n = 7). RESULTS No postoperative complications occurred among the 63 patients, and the postoperative hospital stay was 11 ± 12 days. Fourteen patients (22.2%) had a recurrence of cholecystitis, of whom 7 patients (11.1%) needed the additional-PTGBD after PTGBA. Significantly longer operative time (245 ± 74 vs 159 ± 65 min, P = 0.0017) and postoperative hospital stay (22 ± 27 vs 10 ± 9 d, P = 0.0118) and greater intraoperative blood loss (279 ± 385 vs 70 ± 208 mL, P = 0.0283) were observed among patients in the additional-PTGBD group compared with the only-PTGBA group, whereas the rates of postoperative complications (Clavien-Dindo grade ≥3: 0% each) and conversion to open surgery (28.6% vs 8.9%, P = 0.1705) were comparable. CONCLUSION PTGBA for acute cholecystitis could result in good surgical outcomes of subsequent LC, especially regarding postoperative complications. However, we should keep in mind that the additional-PTGBD after PTGBA failure, which sometimes happened, would be associated with increased operative difficulty and longer recovery.

Abstract
PURPOSE We investigated the potential clinical utility of short-term serial KRAS-mutated circulating cell-free tumor DNA (ctDNA) assessment for predicting therapeutic response in patients undergoing first-line chemotherapy for advanced pancreatic cancer. METHODS We collected 144 blood samples from 18 patients with locally advanced or metastatic cancer that were undergoing initial first-line chemotherapy of gemcitabine plus nab-paclitaxel (GEM plus nab-PTX). Analysis of KRAS-mutated ctDNA was quantified by digital droplet polymerase chain reaction (ddPCR) as mutant allele frequency (MAF). This study investigated pretreatment KRAS-mutated ctDNA status and ctDNA kinetics every few days (days 1, 3, 5 and 7) after initiation of chemotherapy and their potential as predictive indicators. RESULTS Of the 18 enrolled patients, an increase in KRAS-mutated ctDNA MAF values from day 0-7 after initiation of chemotherapy was significantly associated with disease progression (P < 0.001). Meanwhile, positive pretreatment ctDNA status (MAF ≥ 0.02%) (P = 0.585) and carbohydrate antigen 19-9 (CA19-9) values above the median (P = 0.266) were not associated with disease progression. In univariate analysis, this short-term increase in ctDNA MAF values (day 0-7) was found to be associated with significantly shorter progression free survival (PFS) (hazard ration [HR], 24.234; range, (2.761-212.686); P = 0.0002). CONCLUSION This short-term ctDNA kinetics assessment may provide predictive information to reflect real-time therapeutic response and lead to effective refinement of regimen in patients with advanced pancreatic cancer undergoing systemic chemotherapy.

Abstract
Laparoscopic anatomical resection of liver segment II (S2 segmentectomy) using left lateral section-flip up method is introduced to safely and effectively encircle the Glissonean branch of segment II (G2) and to expose the left hepatic vein (LHV). The left lateral section is completely mobilized and then flipped up. After encircling and clamping the G2 root, indocyanine green is intravenously injected and the demarcation line is clearly confirmed by near infrared fluorescence imaging. After exposure of the LHV from the root to this intersegmental plane between segments II/III, residual parenchymal resection is performed using the clamp crushing method. There are two difficulties concerning S2 segmentectomy. The first is encirclement of the G2 root without interfering with the G3. Compared with the conventional front view of the umbilical portion, the view behind the left lateral section contribute to easy confirmation and direct encircle of the G2 root without dividing the G3 and injuring LHV on the same plane. The second difficulty is that the boundary of the visible liver surface between segments II/III does not match the direction of the LHV. This can cause confusion to the operator aiming to perform precise inner parenchymal resection. Our procedure allows easy access to the LHV root and exposure of the peripheral directing hepatic vein. Hepatic vein-guided approaches will likely be helpful in precise performance of inner parts of liver resection.

Abstract
Malignant peripheral nerve sheath tumours (MPNSTs) are malignant tumours arising from a peripheral nerve or displaying nerve sheath differentiation. Most MPNSTs are found on the head, body trunk and extremities, whereas cases in the gastrointestinal are extremely rare. About half arise in neurofibromatosis type 1 patients and 10% arise post-irradiation. This is probably the first small bowel MPNST post-radiation therapy case reported. A 72-year-old female who received radiotherapy 30 years ago for cervical cancer was admitted with progressive abdominal pain and weight loss. Computed tomography revealed a mass with inhomogeneous enhancement in the lumen of the small intestine. Tumour excision was performed with ileocecal and sigmoid colon resection due to suspicion for peripheral tissue invasion. Histopathological examination revealed spindle-shaped cells with focal cartilage differentiation. Together with immunochemistry stain showing complete loss of H3K27me3, a final diagnosis of MPNST was made. The patient is presently under regular follow-ups, and has remained disease-free for 24 months.

Abstract
A 51-year-old woman presented to our hospital complaining of a lower abdominal mass and dysuria. She was diagnosed with advanced sigmoid colon cancer. The tumor was large, involving the bladder, and occupying the pelvic cavity. She received neoadjuvant chemotherapy with 4 courses of mFOLFOX6, in addition to panitumumab. The treatment resulted in a marked reduction of the tumor. A laparoscopic sigmoid colon resection, total cystectomy, neobladder reconstruction, complete uterine and bilateral adnexa resection and partial ileal resection were performed. The histopathological diagnosis was ypT4b(bladder), ypN0, ypStage Ⅱc, all with negative surgical margins. Adjuvant chemotherapy was not administered owing to the patient's refusal. She remained recurrence-free for 3 years of postoperative follow up.

Abstract
Intrahepatic splenosis (IHS) is a rare disease that is considered to result from heterotopic autotransplantation or implantation of splenic tissue after splenic trauma or surgery. A 46-year-old man with a treatment history of a left lateral liver segmentectomy and splenectomy for a road traffic injury 30 years earlier presented to Sakai City Medical Center (Sakai, Japan) with acute abdominal pain in November 2019. Physical examination showed no significant signs, and serum data were normal. Computed tomography revealed a hypodense mass measuring 2.5x1.7 cm in segment 7 of the liver. Gadoxetic acid-enhanced magnetic resonance imaging showed early enhancement in the arterial phase and washout in the delayed phase. Therefore, laparoscopic surgery was performed with a preoperative diagnosis of hepatocellular carcinoma. Pathological examination of the tumor showed IHS. The postoperative course was uneventful, and the patient developed no new abnormal region in the liver during 2 years of follow-up. The present study presented a case of IHS assumed to be hepatocellular carcinoma. IHS should be considered as a differential diagnosis of a liver mass detected years after splenic trauma or surgery, even in cases with imaging patterns suggesting malignancy.

Effects of Roasting Conditions on Antibacterial Properties of Vietnamese Turmeric ( Curcuma longa) Rhizomes. Molecules 2023; 28:7242.

Abstract
Processing with heat treatment has been reported to alter several therapeutic effects of turmeric. In Vietnamese traditional medicine, turmeric has been long used for bacterial infections, and roasting techniques are sometimes applied with this material. However, there have been no studies investigating the effects of these thermal processes on the plant's antibacterial properties. Our study was therefore performed to examine the changes that roasting produced on this material. Slices of dried turmeric were further subjected to light-roasting (80 °C in 20 min) or dark-roasting (160 °C in 20 min) processes. Broth dilution and agar-well diffusion methods were applied to examine and compare the effects of ethanol extracts obtained from non-roasted, light-roasted and dark-roasted samples, on a set of 6 gram-positive and gram-negative bacteria. In both investigations, dark-roasted turmeric was significantly less antibacterial than non-roasted and light-roasted materials, as evident by the higher values of minimum inhibitory concentrations and the smaller diameters of induced inhibitory zones. In addition, dark-roasting was also found to clearly reduce curcumin contents, total polyphenol values and antioxidant activities of the extracts. These results suggest that non-roasting or light-roasting might be more suitable for the processing of turmeric materials that are aimed to be applied for bacterial infections.

Abstract
Scanning electron microscopy (SEM) has realized high-throughput defect monitoring of semiconductor devices. As miniaturization and complexification of semiconductor circuit patterns increase in recent years, so has the number of defects. There is thus a great need to further increase the throughput of SEM defect monitoring. Toward this end, we propose a deep learning-based super-resolution method that reproduces high-resolution (HR) images from corresponding low-resolution images. Image quality factors such as pattern contrast and sharpness are important in SEM HR images in order to evaluate the quality of printed circuit patterns. Our proposed method meets various image quality requirements by changing the loss calculation method pixelwise based on the pattern in the image. It realizes super-resolved images that compare favorably with actual HR images and can improve SEM throughput by 100% or more.

Abstract
BACKGROUND The prognostic impact of radiographic duodenal invasion (rDI) of pancreatic ductal adenocarcinoma (PDAC) has yet to be fully elucidated. This retrospective study aimed to investigate the prognostic and clinicopathological significance of rDI in patients with PDAC after pancreatoduodenectomy (PD). MATERIALS AND METHODS We retrospectively analyzed 223 consecutive patients with resectable (R) and borderline resectable (BR)-PDAC that underwent up-front PD between 2002 and 2018. rDI was assessed by preoperative multi-detector row computed tomography. RESULTS Ninety-three (42%) patients with PDAC had rDI, and all of them had pathological DI (pDI). The rDI(+) group had larger tumor size, BR-PDAC was more common, there was higher serum CA19-9 level, and microscopic lymphovascular invasion was more common than in the rDI(-) group. rDI was associated with significant reduction in overall survival (OS) (P < 0.001) and recurrence-free survival (RFS) (P < 0.001). In multivariate analysis, rDI was an independent prognostic factor in OS [hazard ratio (HR) = 0.52; 95% confidence interval (CI) 0.38-0.73, P < 0.001] and RFS [HR = 0.56; 95% CI 0.40-0.78, P = 0.001]. rDI was also an independent risk factor for early recurrence within 12 months [odds ratio (OR) = 0.36; 95% CI 0.18-0.73, P = 0.005]. rDI had positive correlation with liver recurrence (P = 0.024). CONCLUSION Biological aggressiveness of PDAC with rDI implies short OS and early recurrence with frequent liver metastasis. Aggressive perioperative chemotherapy is recommended to improve prognosis, especially for R-PDAC patients with rDI.

Abstract
PURPOSE/OBJECTIVE(S) Salvage radiotherapy (SRT) to the prostate bed is the only curative treatment for patients with biochemical recurrence (BCR) after radical prostatectomy (RP). Although several systematic reviews indicated that a dose escalation in the range of 60-70 Gy improved biochemical control, the effects of radiation doses on clinical relapse after SRT remain unclear. Our aim was to investigate the relationship between radiation doses and clinical relapse-free survival (cRFS) after SRT. MATERIALS/METHODS We identified 295 eligible patients receiving SRT for biochemically recurrent prostate cancer after RP between 2005 and 2018 at 15 institutions. Sixteen patients (5%) received short-term (< 6 months) androgen deprivation therapy (ADT) following RP and/or concurrently with SRT. SRT was delivered to the prostate and seminal vesicle bed using photon beams at a median (range) dose of 66 Gy (61-85) in 1.8-3.0 Gy fractions. The primary outcome was cRFS. Clinical relapse was identified on radiological imaging and/or biopsy and included local recurrence, lymph node metastasis, and distant metastasis. In all analyses, doses were recalculated as an equivalent dose in 2-Gy fractions (EQD2) with α/β = 1.5 Gy. Clinical RFS between the EQD2 ≥ 66 Gy (n = 229) and EQD2 < 66 Gy (n = 66) groups were compared using the Log-rank test, followed by univariate and multivariate Cox regression analyses and a subgroup analysis. RESULTS The median follow-up duration was 73 months. Among patients with BCR (n = 119), 79 of 96 (82%) in the EQD2 ≥ 66 Gy group and 21 of 23 (91%) in the EQD2 < 66 Gy group received second salvage ADT (p = 0.36). Among all patients (n = 295), clinical relapse was identified in 22 (7%) patients after SRT. Six-year biochemical relapse-free survival (bRFS), cRFS, cancer-specific survival (CSS), and overall survival (OS) rates were 58%, 93%, 98%, and 94%, respectively. Six-year cRFS rates were 94% (95% confidence interval [CI], 90-97) in the EQD2 ≥ 66 Gy group and 87% (95% CI, 75-93) in the EQD2 < 66 Gy group (p = 0.020). The multivariate analysis revealed that EQD2 < 66 Gy, Gleason score ≥ 8, seminal vesicle involvement, and PSA at BCR ≥ 0.5 ng/ml correlated with clinical relapse (p = 0.0016, 0.014, 0.011, and 0.027, respectively). The subgroup analysis showed the consistent benefit of EQD2 ≥ 66 Gy in patients across most subgroups including PSA at BCR after RP, extracapsular extension, and age at SRT. CONCLUSION This large multi-institutional observational study demonstrated that a higher SRT dose (EQD2 ≥ 66 Gy) resulted in superior cRFS. The present result supports the dose recommendations in the 2023 National Comprehensive Cancer Network guidelines (64-72 Gy) even in terms of clinical relapse. Prospective trial is warranted to investigate an upper threshold for optimal SRT dose.

Abstract
The basilar arterial endothelium mediates blood vessel relaxation partly through the release of nitric oxide (NO). Apoptosis of cerebrovascular endothelial cells is linked to a high mortality rate in chickens infected with the highly pathogenic avian influenza virus, but interestingly, ducks exhibit a greater resistance to this virus. In this study, we examined the responsiveness of duck basilar arteries (BAs) to various vasoactive substances, including 5-hydroxytryptamine (5-HT), histamine (His), angiotensin (Ang) II, noradrenaline (NA), acetylcholine (ACh), and avian bradykinin ornithokinin (OK), aiming to characterize the receptor subtypes involved and the role of endothelial NO in vitro. Our findings suggest that arterial contraction is mediated with 5-HT1 and H1 receptors, while relaxation is induced with β3-adrenergic and M3 receptors. Additionally, OK elicited a biphasic response in duck BAs, and Ang II had no effect. Endothelial NO appears to be crucial in relaxation mediated with M3 and OK receptors but not β3-adrenergic receptors in the duck BA. The reduced endothelial NO involvement in the receptor-mediated relaxation response in duck BAs represents a clear difference from the corresponding response reported in chicken BAs. This physiological difference may explain the differences in lethality between ducks and chickens when vascular endothelial cells are infected with the virus.

Abstract
While high-level evidence is lacking, numerous retrospective studies have depicted the value of supplemental oxygen in idiopathic pulmonary fibrosis (IPF) and other interstitial lung diseases, and its use should be encouraged where necessary. The clinical course and survival of patients with IPF who have been introduced to oxygen therapy is still not fully understood. The objective of this study was to clarify overall survival, factors associated with prognosis, and causes of death in IPF patients after the start of oxygen therapy. This is a prospective cohort multicenter study, enrolling patients with IPF who started oxygen therapy at 19 hospitals with expertise in interstitial lung disease. Baseline clinical data at the start of oxygen therapy and 3-year follow-up data including death and cause of death were assessed. Factors associated with prognosis were analyzed using univariable and multivariable analyses. One hundred forty-seven eligible patients, of whom 86 (59%) were prescribed ambulatory oxygen therapy and 61 (41%) were prescribed long-term oxygen therapy, were recruited. Of them, 111 died (76%) during a median follow-up of 479 days. The median survival from the start of oxygen therapy was 537 ± 74 days. In the univariable analysis, low body mass index (BMI), low forced vital capacity (FVC), low diffusion capacity (DLCO), resting hypoxemia, short 6 min-walk distance, and high COPD assessment test (CAT) score were significantly associated with poor prognosis. Multivariable analysis revealed low BMI, low FVC, low DLCO, low minimum SpO2 on 6MWT, and high CAT score were independent factors for poor prognosis. The overall survival of IPF patients after starting oxygen therapy is about 1.5 years. In addition to pulmonary function tests, 6MWT and patient reported outcomes can be used to predict prognosis more accurately.Clinical Trial Registration: UMIN000009322.

Abstract
Essential oils from Cinnamomum cassia bark and Eucalyptus globulus leaves have been traditionally applied for bacterial infections, through both of aromatherapy and oral application. (E)-cinnamaldehyde and 1,8 cineole have been identified as their major secondary metabolites, and are also generally considered as the main active ingredients responsible for their medicinal applications. However, ethnobotanical doctors still prefer to use whole essentials oils over purified compounds in bacterial infections. We therefore hypothesized that multi-compound extracts might exert better effects than isolated ingredients. In order to verify the hypothesis about advantages of whole materials, we examined antibacterial properties of the 2 plant essential oils in the comparison with their isolated major compounds, such as (E)-cinnamaldehyde and 1,8 cineole. Effects of liquid- and vapor-phase were examined on a set of 6 gram-positive and -negative bacteria, applying broth dilution, agar well diffusion and disc volatilization methods. In all 3 investigations, we observed that whole cinnamon and eucalyptus oils, with the lower concentrations of (E)-cinnamaldehyde (89.1%) and 1,8 cineole (61.2%), were able to induce better effects than the purified active compounds (≥ 99%). These results partly explain the advantages of using whole essential oils over isolated ingredients, and therefore support the application of traditional dosage forms for bacterial infections in ethnomedicine.

Abstract
Right anterior liver sectionectomy (RAS) is a complicated procedure with high incidences of postoperative complications. We report a case of right posterior bile duct (RPBD) stricture after laparoscopic RAS with discussion of the anatomical aspects. A 69-year-old Japanese man had solitary colorectal liver metastasis. A tumor was located near the root of the right anterior Glissonean pedicle. On postoperative day 6, he had cholangitis and imaging studies showed RPBD stricture. Symptoms disappeared following a course of antibiotics and the patient was discharged on postoperative day 21. The RBPD anatomy type of this patient was a supra-portal pattern with a long (18 mm) right biliary duct, which would be close to the right anterior Glissonean bifurcation. A stapling device might have caused its deformation and resulted in its stricture. As the RPBD has variant anatomy, we had to notice that there may be hazardous types for postoperative RPBD stricture.

Abstract
Idiopathic pulmonary fibrosis (IPF) is a progressive aging-related lung disease associated with increased lung cancer risk. Although previous studies have shown that IPF worsens the survival of patients with lung cancer, whether IPF independently affects cancer malignancy and prognosis remains inconclusive. Extracellular vesicles (EVs) have recently emerged as active carriers of molecular biomarkers and mediators of intercellular communication in lung homeostasis and pathogenesis. EV cargo-mediated fibroblast-tumor cell communication might participate in the development and progression of lung cancer by modulating various signaling pathways. In this study, we examined the impact of lung fibroblast (LF)-derived EVs on non-small cell lung cancer (NSCLC) malignancy in the IPF microenvironment. Here, we showed that LFs derived from patients with IPF have phenotypes of myofibroblast differentiation and cellular senescence. Furthermore, we found that IPF LF-derived EVs have markedly altered microRNA compositions and exert proproliferative functions on NSCLC cells. Mechanistically, the phenotype was attributed mainly to the enrichment of miR-19a in IPF LF-derived EVs. As a downstream signaling pathway, mir-19a in IPF LF-derived EVs regulates ZMYND11-mediated c-Myc activation in NSCLC, potentially contributing to the poor prognosis of patients with NSCLC with IPF. Our discoveries provide novel mechanistic insights for understanding lung cancer progression in the IPF microenvironment. Accordingly, blocking the secretion of IPF LF-derived EV miR-19a and their signaling pathways is a potential therapeutic strategy for managing IPF and lung cancer progression.

Abstract
Background Pneumonia is common among older adults and often recurrent. Several studies have been conducted on the risk factors for pneumonia; however, little is known about the risk factors for recurrent pneumonia. This study aimed to identify the risk factors for developing recurrent pneumonia among older adults and to investigate methods of prevention. Methods We analysed the data of 256 patients aged 75 years or older who were admitted for pneumonia between June 2014 and May 2017. Moreover, we reviewed the medical records for the subsequent 3 years and defined the readmission caused by pneumonia as recurrent pneumonia. Risk factors for recurrent pneumonia were analysed using multivariable logistic regression analysis. Differences in the recurrence rate based on the types and use of hypnotics were also evaluated. Results Of the 256 patients, 90 (35.2%) experienced recurrent pneumonia. A low body mass index (OR: 0.91; 95% CI: 0.83‒0.99), history of pneumonia (OR: 2.71; 95% CI: 1.23‒6.13), lung disease as a comorbidity (OR: 4.73; 95% CI: 2.13‒11.60), taking hypnotics (OR: 2.16; 95% CI: 1.18‒4.01) and taking histamine-1 receptor antagonist (H1RA) (OR: 2.38; 95% CI: 1.07‒5.39) were risk factors. Patients taking benzodiazepine as hypnotics were more likely to experience recurrent pneumonia than patients not taking hypnotics (OR: 2.29; 95% CI: 1.25-4.18). Conclusion We identified several risk factors for recurrent pneumonia. Among them, restricting the use of H1RA and hypnotics, in particular benzodiazepines, may be useful in preventing the recurrence of pneumonia in adults aged 75 years or older.

Abstract
BACKGROUND Transbronchial cryobiopsy enables high-quality sample collection around the probe tip. Meanwhile, existing cryoprobes have less flexibility and a higher risk of bleeding. The ultrathin cryoprobe with a 1.1-mm diameter addresses these problems and allows specimens to be directly retrieved through the working channel of a thin bronchoscope. OBJECTIVE This study evaluated the diagnostic utility and safety of non-intubated cryobiopsy using an ultrathin cryoprobe added to conventional biopsy for diagnosing peripheral pulmonary lesions (PPLs). METHODS The data of patients who underwent conventional biopsy followed by non-intubated cryobiopsy to retrieve specimens through the thin bronchoscope's working channel for diagnosing PPLs at Osaka Metropolitan University Hospital from July 2021 to June 2022 were retrospectively collected. They were analyzed to evaluate the diagnostic utility and safety of adding non-intubated cryobiopsy to conventional biopsy for PPLs. The characteristics of PPLs that obtain additional diagnostic benefits from cryobiopsy over conventional biopsy were also investigated. RESULTS The analysis included 113 patients. The diagnostic yields of conventional biopsy and non-intubated cryobiopsy were 70.8% and 82.3%, respectively (p = 0.009). The total diagnostic yield was 85.8%, higher than conventional biopsy alone (p < 0.001). Although one moderate bleeding occurred, no severe complications developed. The additional diagnostic benefits of non-intubated cryobiopsy over conventional biopsy were demonstrated when the radial endobronchial ultrasound (R-EBUS) showed "adjacent to" (60.3% vs. 82.8%, p = 0.017). CONCLUSIONS Non-intubated cryobiopsy using an ultrathin cryoprobe has high diagnostic utility and safety for diagnosing PPLs, with additional diagnostic benefits over conventional biopsy depending on the R-EBUS image.

Abstract
INTRODUCTION Atezolizumab plus bevacizumab (ATZ+BV) treatment has become the first-line regimen for unresectable hepatocellular carcinoma (u-HCC). Prediction of response to it might be clinically beneficial. Using peripheral blood parameters, we aimed to construct a prediction model for ATZ+BV treatment. METHODS Clinical records of 119 patients with u-HCC treated by ATZ+BV were retrospectively analyzed. The primary outcome measurement was defined as any-size reduction at the initial image evaluation. Using baseline values of peripheral blood parameters, a prediction model was constructed by univariate and multivariate logistic regression analysis. Validation was performed internally by bootstrap method. RESULTS The primary outcome was achieved in 46 patients. Univariate analysis showed that C-reactive protein (CRP), alpha-fetoprotein (AFP), des-gamma-carboxy prothrombin (DCP), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR) were possible predictors. CRP and DCP, and NLR and PLR had correlation (correlation coefficient >0.3), so we used CRP and NLR as representative factors, respectively. Multivariate analysis constructed the following prediction model: Logit = 1.62-0.61×[CRP] -0.38×[Log10AFP] -0.37×[NLR]. Bootstrapped median (95% confidence interval) of coefficients of CRP, Log10AFP, NLR were -0.64 (-1.46 ∼ -0.11), -0.40 (-0.82 ∼ -0.03), and -0.38 (-0.74 ∼ -0.05), respectively. The area under the receiver operating characteristic curve (95% confidence interval) was 0.73 (0.60-0.80). Median overall survival of the favorably and unfavorably predicted groups were 17.0 and 11.0 months (p = 0.03), respectively. DISCUSSION In patients with u-HCC treated by ATZ+BEV, a prediction model constructed using baseline values of CRP, AFP, and NLR had impact on any-size reduction at the initial image evaluation and on prognosis.

Abstract
BACKGROUND Alectinib, crizotinib, and ceritinib, are anaplastic lymphoma kinase-tyrosine kinase inhibitors (ALK-TKIs) that exhibit high protein binding, and their metabolism is associated with the cytochrome P450 (CYP) isoenzymes 2C9 or 3A4. The plasma protein binding rate of warfarin, which is used to prevent and treat venous thromboembolism, is also high. Warfarin is a racemate of S-warfarin and R-warfarin, which are metabolized by CYP2C9 and CYP3A4, respectively. Reports on the drug interactions between each of the above-mentioned ALK-TKIs and warfarin with concurrent use of bucolome are currently lacking. CASE PRESENTATION We report a case of a patient receiving warfarin and bucolome, whose international normalized ratio (INR) increased after sequential treatment with alectinib, crizotinib, and ceritinib. The patient was a 61-year-old man with a history of aortic valve regurgitation, who was receiving warfarin treatment following aortic valve replacement. Bucolome, which can enhance the effect of warfarin, was also used simultaneously. The patient was diagnosed with primary lung adenocarcinoma, and ALK rearrangement was detected during second-line chemotherapy. After progression of the disease with chemotherapy, sequential treatment with alectinib, crizotinib, and ceritinib was initiated. Pretreatment INR values were in the therapeutic range (target INR of 2-3) but increased to supratherapeutic levels each time after initiation of alectinib, crizotinib, or ceritinib treatment. Adjustment of warfarin dose or discontinuation of bucolome were necessary to maintain the therapeutic INR range. There were no serious bleeding events or substantial changes in dietary intake. Displacement of plasma protein binding or competitive inhibition of metabolism by alectinib, crizotinib, and ceritinib could increase the plasma concentration of the unbound form of warfarin, resulting in high INR values. In addition, alectinib, crizotinib, and ceritinib might cause displacement of bucolome from plasma proteins, followed by displacement of warfarin or inhibition of warfarin metabolism caused by the unbound form of bucolome. CONCLUSIONS Close monitoring of INR and adjustment of warfarin dosage are needed during treatment with alectinib, crizotinib, or ceritinib in patients who receive warfarin with concurrent use of bucolome.

Abstract
Acute hepatitis E, one of the causes of acute liver injury, has been increasingly diagnosed in developed countries in recent years. Misdiagnosis of acute hepatitis E virus (HEV) infection as drug-induced liver injury (DILI) may lead to discontinuation of effective chemotherapy. Thus, viral hepatitis, including hepatitis E, must be ruled out in the diagnosis of DILI. A 78-year-old woman with lung adenocarcinoma and multiple bone metastases received maintenance therapy with pemetrexed + pembrolizumab for a year. Increased aspartate aminotransferase and alanine aminotransferase levels, indicating acute liver injury, were observed. Initially, DILI was suspected, and she was given medications to lower the levels of hepatic enzymes. She was later admitted to the hospital with the chief complaint of general malaise and anorexia. Serum aspartate aminotransferase and alanine aminotransferase levels were markedly elevated (381 and 854 U/L, respectively). Acute HEV infection was diagnosed based on the detection of serum HEV immunoglobulin A antibodies. The patient received liver support therapy, and the serum hepatic enzymes recovered to normal levels. Chemotherapy was resumed without any subsequent relapse of hepatic enzyme elevation. When DILI is suspected during chemotherapy, exclusion of viral hepatitis is mandatory, which can be achieved by measuring markers of hepatitis viruses, including HEV, and examining the patient's detailed medical history.

Abstract
BACKGROUND Physical activity is one of the most important prognostic factors for patients with chronic obstructive pulmonary disease (COPD). Physical activity correlates significantly with skeletal muscle mass and strength. Pulmonary rehabilitation has been conducted to improve physical activity, but its effectiveness has been inconsistent. Nutritional status is also related to physical activity in patients with COPD. The relationships between skeletal muscle mass, strength, and nutritional status evaluated using the Mini Nutritional Assessment Short Form (MNA-SF) were investigated. How nutritional status alters the relationships between physical activity, exercise capacity, skeletal muscle mass, and strength was also investigated. METHODS This retrospective, cross-sectional study enrolled 81 outpatients with COPD. In all patients, physical activity, exercise capacity, body composition assessment, and MNA-SF were assessed. The relationships between physical activity, exercise capacity, skeletal muscle mass, and strength were examined according to the MNA-SF. RESULTS The MNA-SF high group had significantly higher skeletal muscle mass than the MNA-SF low group when skeletal muscle strength was the covariate. In the MNA-SF low group, physical activity positively correlated with skeletal muscle mass. In the MNA-SF high group, physical activity positively correlated with skeletal muscle strength. CONCLUSIONS This study showed that the nutritional status of patients with COPD alters the relationship between physical activity and skeletal muscle mass or strength. Optimizing rehabilitation with nutrition interventions according to nutritional status might improve physical activity in patients with COPD.

Abstract
People who drink naturally hardened water may experience longevity-enhancing effects. In this study, we investigated water hardness and longevity from both geological and epidemiological perspectives in Japan’s Amami islands, where drinking water is drawn from coralline or non-coralline bedrock. We investigated drinking water hardness, limestone bedrock occupancy, and the centenarian rate (number per 10,000 population) by municipality across four adjacent islands (Amami-Oshima (non-coralline), Tokunoshima, Okinoerabu, and Yoron (predominantly coralline)). Limestone was strongly correlated with water hardness (r = 0.99; p < 0.01), occupying more than 80% of the bedrock where the water was the hardest (Tokunoshima’s Isen municipality: 86.5%; Yoron: 82.9%) and being scarcely detectable in Amami-Oshima (0.0 to 0.2%), where the water was the least hard. The centenarian rate was also strongly correlated with water hardness (r = 0.84, p < 0.01), with the highest figures in Yoron (29.7) and Isen (29.2), and the lowest in Amami-Oshima (0.0 to 12.2). Therefore, we hypothesize a potentially beneficial effect of hard water on longevity when that water is drawn from coralline limestone. Water hardness is determined by the water content of calcium and magnesium and may plausibly influence life expectancy through a preventative effect against cardiovascular disease. Our findings are of interest to current debates about future global access to drinking water and its quality.

Abstract
BACKGROUND Surgeons are often faced with optimal resection extent and reconstructive method problems in laparoscopic gastrectomy for gastric cancer in the upper and middle body of the stomach. Indocyanine green (ICG) marking and Billroth I (B-I) reconstruction were used to solve these problems with the organ retraction technique. CASE PRESENTATION A 51-year-old man with upper gastrointestinal endoscopy revealed a 0-IIc lesion in the posterior wall of the upper and middle gastric body 4 cm from the esophagogastric junction. Clinical T1bN0M0 (clinical stage IA) was the preoperative diagnosis. Laparoscopic distal gastrectomy (LDG) and D1 + lymphadenectomy was decided to be performed considering postoperative gastric function preservation. The ICG fluorescence method was used to determine the accurate tumor location since the determination was expected to be difficult to the extent of optimal resection with intraoperative findings. By mobilizing and rotating the stomach, the tumor in the posterior wall was fixed in the lesser curvature, and as large a residual stomach as possible was secured in gastrectomy. Finally, delta anastomosis was performed after increasing gastric and duodenal mobility sufficiently. Operation time was 234 min and intraoperative blood loss was 5 ml. The patient was allowed to be discharged on postoperative day 6 without complications. CONCLUSION The indication for LDG and B-I reconstruction can be expanded to cases where laparoscopic total gastrectomy or LDG and Roux-en-Y reconstruction has been selected for early-stage gastric cancer in the upper gastric body by combining preoperative ICG markings and gastric rotation method dissection.

Abstract
The response of basilar arteries to noradrenaline varies among many animal species, but remains little studied in poultry. Accordingly, we aimed to characterize the adrenergic receptor (AR) subtypes that modulate vascular response in basilar arteries in the chicken, with isometric recording of arterial ring tension using an organ bath. We demonstrated the presence of both alpha and beta (α and β) receptor subtypes through evaluating the response to noradrenaline, with and without a range of β-AR and α-AR antagonists. The concentration-dependent relaxations then induced by a range of β-AR agonists indicated a potency ranking of isoproterenol > noradrenaline > adrenaline > procaterol. We then investigated the effects of β-AR antagonists that attenuate the effect of isoproterenol (propranolol for β1,2,3-ARs, atenolol for β1-ARs, butoxamine for β2-ARs, and SR 59230A for β3-ARs), with Schild regression analysis, ascertaining multiple β-AR subtypes, with neither the β1-AR nor the β2-AR as the dominant subtype. SR 59230A was the only antagonist to yield a pA2 value (7.52) close to the reported equivalent for the relevant receptor subtype. Furthermore, treatment with SR 58611 (a β3-AR agonist) induced relaxation, which was inhibited (P < 0.01) by L-NNA and SR 59230A. Additionally, treating basilar arterial strips (containing endothelium) with SR 58611 induced nitric oxide (NO) production, which was inhibited (P < 0.01) by L-NNA and SR 59230A. Based on this first characterization of AR subtypes in chicken basilar arteries (to our knowledge), we suggest that α- and β-ARs are involved in contraction and relaxation, and that β3-ARs, especially those on the endothelium, may play an important role in vasodilation via NO release.

Abstract
BACKGROUND In Japan, the fourth round of coronavirus disease (COVID-19) vaccination is ongoing and is targeted at medical staff and nursing home workers, individuals aged ≥60 years, and those with comorbidities or other high-risk factors, including body mass index (BMI) ≥30 kg/m2. The incidence of severe COVID-19 decreased markedly after widespread COVID-19 vaccination drives, and our hospital experienced a similar trend. We, therefore, examined the characteristics of our patients to clarify who benefited the most from vaccination. METHODS We retrospectively investigated all patients hospitalized for COVID-19 in Osaka City Juso Hospital between March 1, 2021, and June 30, 2022. Using multivariable logistic analysis, we calculated the adjusted odds ratios (aORs) for severe disease after vaccination in the whole dataset and in subsets stratified by age, sex, BMI, smoking history, pre-hospitalization location, and comorbidities. RESULTS The analysis included 1041 patients. Multivariable logistic analysis showed that vaccination was associated with a low risk of severe disease, with an aOR of 0.21 (95% confidence interval: 0.12-0.36, p < 0.001). On stratifying the analysis according to background characteristics, lower aORs for severe COVID-19 were found for patients aged ≥60 years and for those with diabetes or hypertension. Notably, patients with BMI >30 kg/m2 and those with BMI ≥18 kg/m2 and ≤30 kg/m2 benefited from vaccination. CONCLUSIONS Individuals with diabetes or hypertension and those of age ≥60 years benefited more from vaccination than did their counterparts. We recommend extending the fourth round of vaccinations to individuals with a BMI of 18-30 kg/m2.

Abstract
BACKGROUND The clinical questions of whether chemotherapy as initial treatment, compared with best supportive care (BSC), improves overall survival (OS) and whether it increases the occurrence risk of acute exacerbation of idiopathic interstitial pneumonia (IIP) in patients with advanced-stage lung cancer and IIP remain inconclusive. This study addresses these issues, given that chemotherapy-related acute exacerbation of IIP may be a direct cause of mortality in these patients. METHODS We enrolled 1003 patients from 110 Japanese institutions and collected clinical profiles from 707 and 296 patients in the chemotherapy (men: women, 645:62; mean age, 70.4 ± 6.9 years) and BSC (men: women, 261:35; mean age, 75.2 ± 7.8) groups, respectively. We used propensity score matching to create 222 matched pairs from both groups using patient demographic data (age, sex, smoking status, performance status, history of acute exacerbation of IIP, desaturation on exertion, clinical diagnosis of IIP, high-resolution computed tomography findings, serum fibrotic markers, pulmonary function status, and lung cancer histopathology). Logistic or Cox regression analyses were performed using matched data to assess the effects of chemotherapy on the risk of acute exacerbation of IIP or OS, respectively. RESULTS In the well-matched cohort, chemotherapy improved OS (hazard ratio: 0.629, 95% confidence interval [CI]: 0.506-0.783, p < 0.0001); however, it involved significant acute exacerbation of IIP (odds ratio: 1.787, 95% CI: 1.026-3.113) compared to BSC. CONCLUSIONS Compared with BSC, chemotherapy can improve OS in patients with advanced-stage lung cancer and IIP; however, it increases the risk of acute exacerbation of IIP.

Abstract
Insufficient evidence has been accumulated regarding associations of heated tobacco products (HTPs) use with coronavirus infection and severity of coronavirus disease 2019 (COVID-19), an ongoing pandemic. We conducted a cross-sectional study using data from an internet questionnaire administered in February 2022 to 30,130 individuals from the general Japanese population (age range, 16-81 years). Single users of HTPs and dual users of combustible cigarettes and HTPs comprised 5.2% and 7.3% of respondents, and 6.7% and 38.0% of those infected (n = 1117). Approximately 70% of infected dual users experienced severe disease. Single users of HTPs and dual users were more likely to be infected with coronavirus than never-users (adjusted odds ratio [aOR] = 1.65/4.66; 95% confidence interval [CI] 1.26-2.15/3.89-5.58). Regarding severity, former and current tobacco users (former/combustible cigarettes/HTPs: aOR = 1.88/3.17/1.90; 95%CI 1.11-3.19/1.77-5.67/1.01-3.59) were more likely to be administered oxygen than never-users, and dual users required oxygen administration the most (aOR = 4.15, 95%CI 2.70-6.36). Use of HTPs may increase risks of coronavirus infection and severe COVID-19. Our results provide an opportunity to consider the safety of tobacco products use, including HTPs, during the COVID-19 pandemic.

Abstract
BACKGROUND Numerous studies investigated patients with IPF; however, only a few examined patients with idiopathic interstitial pneumonias (IIPs). METHODS The Japanese Idiopathic Interstitial Pneumonias (JIPS) Registry, which was initiated in December 2016, is a multicenter prospective observational study of patients newly diagnosed with IIPs from 86 facilities treating ILDs. The plan is to enroll more than 600 new patients during the 2-year enrolment period and to follow their progress for 3 years after the last case enrolment. If additional consent is obtained, the study will continue for another 2 years. Research questions mainly focus on identifying the frequency by IIP classification, patient background, and diagnostic methods during enrolment, survival, acute exacerbation rate, changes in high-resolution CT imaging, forced vital capacity, and interstitial pneumonia markers over time. Other research questions, including those regarding disease behavior in patients with progressive fibrosing-ILD and new biomarkers associated with genetic predispositions, will be investigated. DISCUSSION The JIPS Registry will provide a comprehensive description of the disease progression, prognosis, treatment status, new biomarkers, and validity of guidelines and central multidisciplinary decisions for IPF and similar diseases that can be differentiated from IPF among IIPs. ETHICS AND DISSEMINATION Ethical approval was obtained from the institutional review board of Kanagawa Cardiovascular and Respiratory Center (KCRC-16-0005), and that of Jichi Medical University approved the biobank part (I18-005). Results will be published in peer-reviewed journals and will be presented at national and international conferences. TRIAL REGISTRATION ClinTrials.gov Registry (NCT03041623, first posted on February 3, 2017).

Abstract
A 58-year-old man presented with dyspnea on exertion and diffuse ground-glass opacities with mosaicism on chest computed tomography in April 201X. A transbronchial lung biopsy revealed organizing pneumonia and lymphocytic infiltration, and steroids were administered. During steroid tapering, the shortness of breath and ground-glass opacities recurred, and a transbronchial lung re-biopsy revealed organizing pneumonia without a granuloma again. Based on the clinical history, imaging features, and amount of humidifier usage, hypersensitivity pneumonitis caused by a humidifier was suspected. The inhalation challenge test was considered positive, and the diagnosis was confirmed. There have been some reports of unidentified granuloma in patients with humidifier lungs. Therefore, this case suggests that humidifier lung should be considered as a possibility even if pathological examination does not reveal granulomas and inflammatory changes such as organizing pneumonia are the only findings.

Abstract
We report a hepatocellular carcinoma(HCC)case with lung metastasis that was successfully treated with transarterial chemoembolization(TACE)and percutaneous radiofrequency ablation(RFA). A man in his 60s took right robe liver resection for HCC after TACE for its rupture. Lung metastasis occurred at S1+2 and S6 in the left lung, and an adverse event interrupted standard molecular target therapies. Because extrahepatic metastasis had been seen only in these two locations for a long time, TACE was performed for both metastases. The feeders for both lesions were each intercostal artery, and controlling the drug inflow was necessary to avoid drug influx into the spinal cord branches when S6 metastasis was treated. The viable lesion remained in the S6 lesion, so RFA was added for both lung metastases. 100% tumor necrosis has been observed since the RFA.

Abstract
A 68-year-old man was referred to our hospital because of back pain during swallowing. Upper gastrointestinal endoscopy revealed a lower esophageal type 3 tumor. The patient was diagnosed with esophageal squamous cell carcinoma by the biopsy specimen. CT scan showed thoracic lower esophagus wall thickening, left paracardiac lymph node swelling, and a low-density area in the liver. Therefore, the patient was diagnosed with Stage Ⅳb esophageal cancer. After introducing cisplatin plus 5-FU combination therapy, the liver metastasis disappeared. After 9 chemotherapy courses, the patient received radical chemoradiotherapy. After completing chemoradiotherapy, the patient was followed up without any treatment. After 3 years since the treatment initiation, the patient is surviving without any relapse.

Abstract
We present a case of a 72-year-old man diagnosed with rectal cancer invading the urinary bladder/prostate. Preoperative chemoradiotherapy substantially reduced the tumor size. In collaboration with urologists, robot-assisted low anterior resection with total cystectomy was performed using the da Vinci Xi system. Depending on the surgical situation, the colorectal surgeon and urologist could smoothly and rapidly play the role of a console surgeon. Although the first robot-assisted multi-organ resection of our institution, the surgery was completed safely without any complications. Although the patient developed urinary tract infection postoperatively, he recovered and was discharged after postoperative 23 days. In conclusion, robot-assisted surgery would be useful in pelvic surgery involving multiple departments such as colorectal surgery, urology, and gynecology.

Abstract
OBJECTIVE This study assessed whether neoadjuvant chemoradiotherapy (CRT) with S-1 increases the R0 resection rate in BRPC. SUMMARY OF BACKGROUND DATA Although a multidisciplinary approach that includes neoadjuvant treatment has been shown to be a better strategy for BRPC than upfront resection, a standard treatment for BRPC has not been established. METHODS A multicenter, single-arm, phase II study was performed. Patients who fulfilled the criteria for BRPC received S-1 (40 mg/m 2 bid) and concurrent radiotherapy (50.4 Gy in 28 fractions) before surgery. The primary endpoint was the R0 resection rate. At least 40 patients were required, with a 1-sided α = 0.05 and β = 0.05 and expected and threshold values for the primary endpoint of 30% and 10%, respectively. RESULTS Fifty-two patients were eligible, and 41 were confirmed to have definitive BRPC by a central review. CRT was completed in 50 (96%) patients and was well tolerated. The rate of grade 3/4 toxicity with CRT was 43%. The R0 resection rate was 52% among the 52 eligible patients and 63% among the 41 patients who were centrally confirmed to have BRPC. Postoperative grade III/IV adverse events according to the Clavien-Dindo classification were observed in 7.5%. Among the 41 centrally confirmed BRPC patients, the 2-year overall survival rate and median overall survival duration were 58% and 30.8 months, respectively. CONCLUSIONS S-1 and concurrent radiotherapy seem to be feasible and effective at increasing the R0 resection rate and improving survival in patients with BRPC. TRIAL REGISTRATION UMIN000009172.

Abstract
RATIONALE Bronchial schwannomas are extremely rare among the benign tracheobronchial tumors and little are known about its epidemiology and optimal clinical management. Here, we report a case of bronchial schwannoma in a young Japanese man and clinical implications about epidemiology, symptom, diagnosis, and treatment of bronchial schwannoma. PATIENTS CONCERN A 37-year-old man visited our department with a nodule incidentally found on his chest radiograph during a routine medical checkup. DIAGNOSIS The tumor was diagnosed as a bronchial schwannoma after pathological evaluation. Microscopically, the tumor consisted of spindle cell proliferation characterized by an alternating highly ordered cellular Antoni A component with occasional nuclear palisading and a loose myxoid Antoni B component. Tumor cells were immunoreactive for S100 but not for smooth muscle actin or KIT. INTERVENTIONS A video-assisted right middle and lower bilobectomy was performed. OUTCOME He remains under observation without recurrence. LESSONS In our review, many reports have come from Asian countries. Bronchial schwannoma can occur within a wide range of age groups and in both men and women. No difference in incidence was observed between right and left bronchial tree. Bronchial schwannoma is sometimes difficult to differentiate from malignant diseases. We should include bronchial schwannoma as one of the differential diagnoses of primary bronchial tumors.

Abstract
Bovine lactoferrin (BLF) reportedly lowers blood pressure and induces vasorelaxation, but its effect on nitric oxide (NO) production has not been established. Accordingly, we aimed to determine whether BLF induces NO production in bovine aortic endothelial cells, and the effects of extracellular free magnesium (Mg) ion concentrations on this NO production. BLF induced NO production time-dependently. NO production was markedly inhibited by the NO synthase inhibitor, NG-nitro-L-arginine methyl ester, in an effect abolished by L-arginine, but not D-arginine. NO production was suppressed at low concentrations, and enhanced at high concentrations, of Mg ions in culture medium. These results suggest that BLF has an important role in hypotensive effects. Mg ions may affect BLF-induced NO production.

Abstract
Skin cryptococcosis often manifests as an umbilicated papule, and chest computed tomography findings of multiple nodules and cavities are also characteristic. The combination of characteristic cutaneous manifestations and radiological findings can help clinicians make an “at‐a‐glance” diagnosis of disseminated cryptococcosis.

Abstract
In 2019, the American College of Rheumatology (ACR) and the European League Against Rheumatism (EULAR) proposed classification criteria for IgG4-related disease (IgG4-RD) [1,2]. IgG4-RD can cause fibroinflammatory lesions characterised by infiltration of abundant IgG4-positive plasma cells with fibrosis and an elevated serum IgG4 concentration [3–5]. Approximately 35% of patients with IgG4-RD present with intrathoracic lesions, including those involving the mediastinal lymph nodes, bronchial walls and peribronchovascular bundles [6–8]. To increase diagnostic sensitivity and specificity, we previously proposed diagnostic criteria for IgG4-related respiratory disease (IgG4-RRD) [9]. In this study, ILDs involving IgG4-positive plasma cell infiltration were classified using the 2019 ACR/EULAR criteria. Most IgG4-positive interstitial pneumonia cases were excluded, suggesting the need for a unique treatment strategy.https://bit.ly/38GiUJM

Abstract
INTRODUCTION Subtotal cholecystectomy (STC) has become recognized as a "bailout procedure" to prevent bile duct injury in patients undergoing laparoscopic cholecystectomy (LC). Predictors of conversion to STC have not been identified because LC difficulty varies based on pericholecystic inflammation. We analyzed data from patients enrolled in a previously performed multi-institutional retrospective study of the optimal timing of LC after gallbladder drainage for acute cholecystitis (AC). These patients presumably had a considerable degree of pericholecystic inflammation. METHODS In total, 347 patients who underwent LC after gallbladder drainage for AC were analyzed to examine preoperative and perioperative factors predicting conversion to STC. RESULTS Three hundred patients underwent total cholecystectomy (TC) and 47 underwent conversion to STC. Eastern Cooperative Oncology Group Performance Status (ECOG PS) (P < .01), severity of cholecystitis (P = .04), previous history of treatment for common bile duct stones (CBDS) (P < .01), and surgeon experience (P = .03) were significantly associated with conversion to STC. Logistic regression analyses showed that ECOG PS (odds ratio 0.2; P < .0001) and previous history of treatment for CBDS (odds ratio 0.37; P = .0073) were independent predictors of conversion to STC. Our predictive risk score using these two variables suggested that a score ≥2 could discriminate between TC and STC (P < .0001). CONCLUSION Poor ECOG PS and previous history of treatment for CBDS were significantly associated with conversion to STC after gallbladder drainage for AC.

Abstract
Immunoglobulin (Ig) G4-positive cells are rarely observed in the lungs of patients with idiopathic interstitial pneumonias (IIPs). IgG1 may be more pathogenic than IgG4, with IgG4 having both pathogenic and protective roles in IgG4-related disease (IgG4-RD). However, the role of both IgG1 and IgG4 in IIPs remains unclear. We hypothesized that patients with IgG4-positive interstitial pneumonia manifest different clinical characteristics than patients with IgG4-RD. Herein, we identified the correlation of the degree of infiltration of IgG1- and IgG4-positive cells with IIP prognosis, using a Japanese nationwide cloud-based database. We included eighty-eight patients diagnosed with IIPs after multidisciplinary discussion, from April 2009 to March 2014. IgG4-positive cell infiltration was identified in 12/88 patients with IIPs and 8/41 patients with idiopathic pulmonary fibrosis (IPF). Additionally, 31/88 patients with IIPs and 19/41 patients with IPF were diagnosed as having IgG1-positive cell infiltration. IgG4-positive IIPs tended to have a better prognosis. Conversely, overall survival in cases with IgG1-positive IPF was significantly worse. IIPs were prevalent with IgG1- or IgG4-positive cell infiltration. IgG1-positive cell infiltration in IPF significantly correlated with a worse prognosis. Overall, evaluating the degree of IgG1-positive cell infiltration may be prognostically useful in cases of IPF.
