Abstract
Although inhalation therapy represents a promising drug delivery route for the treatment of respiratory diseases, the real-time evaluation of lung drug deposition remains an area yet to be fully explored. To evaluate the utility of the photo reflection method (PRM) as a real-time non-invasive monitoring of pulmonary drug delivery, the relationship between particle emission signals measured by the PRM and in vitro inhalation performance was evaluated in this study. Symbicort® Turbuhaler® was used as a model dry powder inhaler. In vitro aerodynamic particle deposition was evaluated using a twin-stage liquid impinger (TSLI). Four different inhalation patterns were defined based on the slope of increased flow rate (4.9-9.8 L/s2) and peak flow rate (30 L/min and 60 L/min). The inhalation flow rate and particle emission profile were measured using an inhalation flow meter and a PRM drug release detector, respectively. The inhalation performance was characterized by output efficiency (OE, %) and stage 2 deposition of TSLI (an index of the deagglomerating efficiency, St2, %). The OE × St2 is defined as the amount delivered to the lungs. The particle emissions generated by four different inhalation patterns were completed within 0.4 s after the start of inhalation, and were observed as a sharper and larger peak under conditions of a higher flow increase rate. These were significantly correlated between the OE or OE × St2 and the photo reflection signal (p < 0.001). The particle emission signal by PRM could be a useful non-invasive real-time monitoring tool for dry powder inhalers.

Abstract
Rationale: There have been meta-analyses that showed reduced retinal nerve fiber layer (RNFL) thickness, which is a surrogate marker of glaucoma, in patients with obstructive sleep apnea (OSA). However, the sample sizes in these reports were small (<300), and the mechanism of RNFL thinning in patients with OSA was not revealed.Objectives: To investigate the relationship of RNFL thickness with nocturnal hypoxemia or hypoxemic burden in a large-scale study.Methods: In this epidemiological study, 8,309 community residents were enrolled. The actigraphy-modified 3% oxygen desaturation index (acti-ODI3%) and cumulative percentage of sleep time with oxygen saturation <90% (acti-CT90) modified by objective sleep duration using actigraphy were measured. The hypoxemic burden is shown as acti-CT90. Circumpapillary RNFL thickness was determined using optical coherence tomography.Results: Multivariable logistic analysis models revealed that an increase in acti-CT90 was significantly associated with mean RNFL thinning after adjusting for several factors in participants without glaucoma diagnosed or treated previously (β = -0.037; P = 0.009). There were significant differences in mean RNFL thickness among participants stratified according to acti-CT90 (>1.5 vs. ⩽1.5; P = 0.04). Although acti-ODI3% was significantly associated with acti-CT90 (β = 0.72; P < 0.0001), acti-ODI3% was not significantly associated with mean RNFL thickness in the multivariable logistic analysis (β = -0.011; P = 0.48). In addition, acti-CT90 was significantly associated with mean RNFL thickness both in the elderly (⩾60 yr; β = -0.058; P = 0.002) and nonelderly (<60 yr; β = -0.054; P = 0.007).Conclusions: Acti-CT90, but not acti-ODI3%, was associated with mean RNFL thinning in participants irrespective of age in the elderly or nonelderly. Further prospective studies are required to investigate whether the prevention of hypoxic burden, which was shown as acti-CT90 in this study, is favorable for RNFL thinning.

Abstract
Remdesivir plays a key role in the treatment of coronavirus disease in 2019 (COVID-19). Haemodialysis is sometimes required for hospitalised patients with COVID-19, and patients undergoing haemodialysis are at an increased risk of severe COVID-19. In the present study, we report the serum concentrations of GS-441524, the active metabolite of remdesivir, in four patients undergoing continuous renal replacement therapy (CRRT). Patient 1, a male aged 70s, received a loading dose of 200 mg remdesivir on day 1, followed by 100 mg remdesivir from day 2, according to the package insert as in non-haemodialysis patients. The mean trough serum concentration of GS-441524 was 783.5 ng/mL, which was approximately 7-fold higher than the mean for patients with an estimated glomerular filtration rate (eGFR) ≥ 60 mL/min. Patients 2-4 received a loading dose of 200 mg remdesivir on day 1, followed by 100 mg once every 2 days from day 2. The mean trough serum concentrations of GS-441524 were 302.2 ng/mL, 585.8 ng/mL and 677.3 ng/mL, respectively. These were 3 to 6-fold higher than the mean for patients with eGFR ≥60 mL/min. The target doses for patients 1, 2, 3, and 4 receiving CRRT were 13.6 mL/kg/h, 6.0-12.5 mL/kg/h, 20.1 mL/kg/h, and 15.1 mL/kg/h, respectively, using a polysulphone membrane. The package insert dose of remdesivir is an overdose for CRRT patients with a target dose of 10-20 mL/kg/h. In low-intensity CRRT, as in Japan, it may be necessary to extend the interval between the doses of remdesivir.

Abstract
BACKGROUND Regarding the therapeutic target in asthma, super-responder status (SR) is a status without systemic corticosteroids. Recently, clinical remission (CR), being a status of prolonged absence of asthma symptoms without systemic corticosteroids and/or normal pulmonary function, has gained attention as a new therapeutic target in asthma. Here, we examined the percentage and features of asthma patients on treatment with dupilumab showing SR and CR. MATERIALS AND METHODS 49 asthma patients used subcutaneous dupilumab for > 1 year between April 2019 and November 2022. The status of SR and CR for 1 year was evaluated. Patients without any maintenance oral corticosteroids and exacerbations requiring systemic corticosteroids were classified as SR. CR was defined using three definitions based on changes in asthma symptoms and pulmonary function in addition to achieving SR for 1 year: CR without pulmonary function criteria (CR w/o F), fulfilment of asthma symptom improvement (asthma control questionnaire score < 0.75 or asthma control test score ≥ 23); and CR-70 or CR-80, pulmonary function improvement (%forced expiratory volume in 1 second ≥ 70% or ≥ 80%) in addition to achieving CR w/o F, respectively. RESULTS 38 (77.6%), 22 (44.9%), 13 (26.5%), 12 (24.5%) of patients had SR, CR w/o F, CR-70, and CR-80, respectively. Severe eosinophilic chronic rhinosinusitis was significantly more found in patients with SR and CR based on all three definitions than in those without. CONCLUSION This study identified the percentage and features of patients on treatment with dupilumab showing SR and CR in a real-world setting. The outcome beyond CR on biologic treatment should be clarified.

Abstract
Chylous ascites is a rare post operative complication after gastrectomy, which commonly occurs in early postoperative period. Here, we successfully treated a patient with unresectable gastric cancer who occurred chylous ascites 9 months after first surgery and underwent laparoscopic surgery for chylous ascites. Since prolonged chylous ascites may cause malnutrition, surgical treatment should be considered for refractory chylous ascites.

Abstract
Sleep-disordered breathing (SDB) is often accompanied by noncommunicable diseases (NCDs), including gout. However, the association between serum uric acid (sUA) levels and NCDs is complicated in patients with SDB. We aimed to clarify this issue utilizing large-scale epidemiological data. This community-based study included 9850 inhabitants. SDB and its severity were assessed by a 3% oxygen desaturation index (3% ODI) corrected for sleep duration using wrist actigraphy. The associations between sUA and moderate to severe SDB (MS-SDB) and sUA and NCDs in patients with MS-SDB were analyzed. A total of 7895 subjects were eligible. In females, the prevalence of MS-SDB increased according to an elevation in sUA levels even after adjusting for confounders, and sUA ≥ 5 mg/dL was the threshold. These were not found in males. There was a positive interaction between sUA ≥ 5 mg/dL and female sex for MS-SDB. In females with MS-SDB, the prevalence of diabetes mellitus (DM) increased according to an elevation in sUA levels, and those with sUA ≥ 5 mg/dL showed a higher prevalence of DM than their counterparts. There is a clear correlation between sUA levels and the severity of SDB, and elevated sUA poses a risk for DM in females with MS-SDB.

Abstract
Excessive daytime sleepiness (EDS) is a symptom of sleep apnea syndrome (SAS). In some patients with SAS who undergo continuous positive airway pressure (CPAP) therapy, EDS persists (residual EDS). However, knowledge of residual EDS in Japan is limited. Therefore, we examined EDS as defined by the Japanese version of the Epworth Sleepiness Scale (a score of ≥11) before and after long-term (≥1 year) CPAP therapy in 490 patients with SAS. Good adherence to CPAP therapy was defined as its use for at least 4 h during 70% of the nights. The prevalence of residual EDS was 9.4%. Residual EDS was negatively associated with good adherence to CPAP therapy. Furthermore, the longer the CPAP therapy duration after initiation, the lower the prevalence of residual EDS. Therefore, the findings on the prevalence of residual EDS and its association with CPAP therapy in Japan are probably similar to those of other countries.

Abstract
Sleep disordered breathing (SDB), mainly obstructive sleep apnea (OSA), constitutes a major health problem due to the large number of patients. Intermittent hypoxia caused by SDB induces alterations in metabolic function. Nevertheless, metabolites characteristic for SDB are largely unknown. In this study, we performed gas chromatography-mass spectrometry-based targeted metabolome analysis using data from The Nagahama Study (n = 6373). SDB-related metabolites were defined based on their variable importance score in orthogonal partial least squares discriminant analysis and fold changes in normalized peak-intensity levels between moderate-severe SDB patients and participants without SDB. We identified 20 metabolites as SDB-related, and interestingly, these metabolites were frequently included in pathways related to fructose. Multivariate analysis revealed that moderate-severe SDB was a significant factor for increased plasma fructose levels (β = 0.210, P = 0.006, generalized linear model) even after the adjustment of confounding factors. We further investigated changes in plasma fructose levels after continuous positive airway pressure (CPAP) treatment using samples from patients with OSA (n = 60) diagnosed by polysomnography at Kyoto University Hospital, and found that patients with marked hypoxemia exhibited prominent hyperfructosemia and their plasma fructose levels lowered after CPAP treatment. These data suggest that hyperfructosemia is the abnormality characteristic to SDB, which can be reduced by CPAP treatment.

Abstract
Servo-ventilation (SV) was developed for treating central sleep apnea. To date, primarily SV devices manufactured by Philips Respironics and ResMed are used. However, the difference in reaction to sleep-disordered breathing events between bilevel positive airway pressure AutoSV devices from Philips and adaptive SV devices from ResMed in clinical settings is unknown. Herein, we describe a case of central sleep apnea in which sleep-disordered breathing events were successfully controlled and sleepiness, sleep quality, and tolerance of the device were improved by changing from the bilevel positive airway pressure AutoSV device from Philips to the adaptive SV device from ResMed. Changing the SV devices can be a clinical option to appropriately control sleep-disordered breathing events in patients receiving SV therapy who present with persistent sleep-disordered breathing.

Abstract
Advanced systemic sclerosis-associated interstitial lung disease (SSc-ILD) can be treated with lung transplantation. There is limited data on lung transplantation outcomes in patients with SSc-ILD, in non-Western populations.We assessed survival data of patients with SSc-ILD, on the lung transplant (LT) waiting list, and evaluated post-transplant outcomes in patients from an Asian LT center. In this single-center retrospective study, 29 patients with SSc-ILD, registered for deceased LT at Kyoto University Hospital, between 2010 and 2022, were identified. We investigated post-transplant outcomes in recipients who underwent LT for SSc-ILD, between February 2002 and April 2022. Ten patients received deceased-donor LT (34%), two received living-donor LT (7%), seven died waiting for LT (24%), and ten survived on the waiting list (34%). Median duration from registration to deceased-donor LT was 28.9 months and that from registration to living-donor LT or death was 6.5 months. Analysis of 15 recipients showed improved forced vital capacity with a median of 55.1% at baseline, 65.8% at 6 months, and 80.3% at 12 months post-transplant. The 5-year survival rate for post-transplant patients with SSc-ILD was 86.2%. The higher post-transplant survival rate at our institute than previously reported suggests that lung transplantation is acceptable in Asian patients with SSc-ILD.

Abstract
In June 2021, Philips Respironics first advised the use of in-line bacterial filters in response to a recall of continuous positive airway pressure (CPAP) devices. However, the effects of using in-line filters with CPAP devices have not yet been examined in a clinical setting. Here, we retrospectively evaluated 160 patients with sleep-disordered breathing (SDB) who voluntarily used in-line bacterial filters. Patients' perceptions of CPAP pressure after using in-line filters were investigated via a verbal interview. Patients described CPAP pressure as very weak (13, 8.1%), somewhat weak (42, 26.2%), unchanged (103, 64.4%), or somewhat strong (2, 1.3%). Five of the thirteen patients (38.5%) who described CPAP pressure as very weak discontinued the use of in-line filters. The apnea-hypopnea index obtained from the CPAP devices did not change after using in-line filters (n = 129, p = 0.85). Hence, although in-line bacterial filters could change patients' perceptions of CPAP pressure, they did not influence SDB control.

Abstract
We reported a case in which a pancreatic resection was performed for pancreatic metastasis of renal cell carcinoma 24 years after nephrectomy, and a residual pancreatectomy was performed 4 years later for residual pancreatic recurrence. The patient was a 72-year-old. In 1991, he underwent right nephrectomy for right renal cell carcinoma. During follow-up, in 2015, mass lesions were noted in the pancreatic tail and distal pancreatectomy was performed on suspicion of pancreatic neuroendocrine tumor(NET). Pathological examination diagnosed metastasis of renal cell carcinoma. In 2019, mass lesions were noted in the residual pancreas and total pancreatectomy was performed. Pathological examination diagnosed metastasis of renal cell carcinoma. There was 5 cases in Japan, including an our case, in which pancreatectomy was performed again after pancreatectomy for pancreatic metastasis of renal cancer, and the average time until the first pancreatic metastasis was pointed out was 11.8 years, and the average time until pancreatic recurrence was 9.4 years. Pancreatic metastasis of renal cell carcinoma shows heterochronic and multiple metastasis occurs, requiring long-team follow-up. When determining the extent of resection, it was suggested that the minimum number of repetitions necessary may lead to a long-term prognosis, taking into account the patient's age, background.

Abstract
BACKGROUND Living-donor lobar lung transplantation (LDLLT) remains a life-saving option for pediatric patients with respiratory failure. However, the long-term survival and post-transplant quality of adult lobar grafts transplanted into children are unknown. Therefore, this study aimed to evaluate the outcomes of pediatric LDLLT and post-transplant graft growth. METHODS We retrospectively reviewed the prospectively collected clinical data of 25 living-donor lung transplantations performed in 24 pediatric recipients aged ≤17 years. The annual pulmonary function test data and computed tomography scans of 12 recipients, followed up for >5 years without significant complications, were used to evaluate growth in height, graft function, and radiological changes. The Kaplan-Meier method and simple linear regression were performed for analysis. RESULTS Bilateral lower lobe transplantation was performed in 12 patients, unilateral lower lobe transplantation in 12, and bilateral middle lobe transplantation in 1. The median volumetric size matching at transplantation was 142% (range, 54%-457%). The 5- and 10-year overall survival rates were 87.7% and 75.1༅, respectively. Chronic lung allograft dysfunction occurred in 2 patients. During a median follow-up of 6 years, the median increases in height and vital capacity were 14.4% (range, 0.80%-43.5%) and 58.5% (range, 6.7%-322%), respectively. Graft weight was positively correlated with graft volume (r2=0.622, p<0.001) after the graft volume exceeded the original lobar volume in the donor. CONCLUSIONS This study shows that pediatric LDLLT offers satisfactory long-term survival, with the growth of mature adult lobes transplanted into growing children.

Abstract
Background The effects of continuous positive airway pressure (CPAP) devices on obstructive sleep apnea (OSA) in Japanese patients have not been reported. We assessed the effects of changing CPAP devices (from the Philips Respironics device to the ResMed device) on the control of OSA. Methods We retrospectively examined 13 patients with OSA who voluntarily changed from the Philips Respironics device to the ResMed device due to a Philips Respironics CPAP device recall. Data on the apnea-hypopnea index (AHI) were obtained from the CPAP devices for three months before and after changing the devices. Results The AHI obtained from the CPAP devices significantly decreased from 4.4 (3.1-10.7) events/h to 2.0 (0.8-3.6) events/h when patients changed devices (P=0.022). The AHI decreased to <5 events/h after changing devices in 4 patients, whereas it had been ≥5 events/h before changing devices in 6 patients. Conclusion Changing CPAP devices can decrease the AHI.

Abstract
BACKGROUND Telemonitoring the use of CPAP devices and remote feedback on device data effectively optimizes CPAP adherence in patients with OSA. RESEARCH QUESTION Can expanding the scope of telemonitoring and remote feedback to body weight (BW), BP, and physical activity enhance efforts for BW reduction in Patients with OSA receiving CPAP? STUDY DESIGN AND METHODS Participants were recruited from patients at 16 sleep centers in Japan with OSA and obesity who were receiving CPAP therapy. Obesity was defined as a BMI of ≥ 25 kg/m2, based on Japanese obesity guidelines. Implementation of CPAP telemonitoring was enhanced with electronic scales, BP monitors, and pedometers that could transmit data from devices wirelessly. Participants were randomized to the multimodal telemonitoring group or the usual CPAP telemonitoring group and were followed up for 6 months. Attending physicians provided monthly telephone feedback calls to the usual CPAP telemonitoring group on CPAP data obtained remotely. In the multimodal telemonitoring group, physicians additionally encouraged participants to reduce their BW, after sharing the remotely obtained data on BW, BP, and step count. The primary outcome was set as ≥ 3% BW reduction from baseline. RESULTS One hundred sixty-eight participants (BMI, 31.7 ± 4.9 kg/m2) completed the study, and ≥ 3% BW reduction occurred in 33 of 84 participants (39.3%) and 21 of 84 participants (25.0%) in the multimodal telemonitoring and usual CPAP telemonitoring groups, respectively (P = .047). Whereas no significant differences were found between the two groups in the change in office and home BP, daily step counts during the study period were significantly higher in the multimodal telemonitoring group than in the usual CPAP telemonitoring group (4,767 steps/d [interquartile range (IQR), 2,864-6,617 steps/d] vs 3,592 steps/d [IQR, 2,117-5,383 steps/d]; P = .02) INTERPRETATION: Multimodal telemonitoring may enhance BW reduction efforts in patients with OSA and obesity.

Abstract
Recently an association between blood glucose dysregulation and sleep disruption was suggested. The association between sleep disordered breathing, most of which is due to obstructive sleep apnea (OSA) in the general population, and diabetic severity, as well as the impact of antidiabetic treatment, remains unclear. This study aimed to investigate these associations as well as age and sex differences. This cross-sectional study evaluated 7,680 community participants as the main cohort (population-based cohort). OSA was assessed by the 3% oxygen desaturation index from pulse oximetry, which was corrected for sleep duration obtained by wrist actigraphy. For arguing the limitations for using pulse oximetry, 597 hospitalised patients, who were assessed by the apnea-hypopnea index from attended polysomnography, were also evaluated as the validation cohort (hospital-based cohort). Moderate-to-severe OSA was more prevalent as haemoglobin A1c (HbA1c) levels increased (<5.6%/5.6%-<6.5%/6.5%-<7.5%/≥7.5%, respectively) in both cohorts (p < 0.001), but only in those without antidiabetic treatment. The HbA1c level was an independent factor for moderate-to-severe OSA (population-based cohort, odds ratio [OR] 1.26, 95% confidence interval [CI] 1.10-1.45; hospital-based cohort, OR 1.69, 95% CI 1.22-2.33, per 1% increase). These associations were more prominent in the middle-aged (aged <60 years) than in the elderly (aged ≥60 years) and in women than in men in both cohorts. The prevalence of moderate-to-severe OSA in patients with antidiabetic treatment in the hospital-based cohort was ≥75% regardless of HbA1c levels. In conclusion, an association between the prevalence of OSA and HbA1c level even within or over the normal range was found only in patients without antidiabetic treatment and was more prominent in the middle-aged and in women.

Abstract
Recurrent gastric cancer(GC)with splenic metastasis showed poor prognosis, and its treatment strategy remains unclear. Recently, studies identified the considerable prognostic effect of metastasectomy in GC following intensive chemotherapy. Here, we successfully treated a patient with Epstein-Barr virus-positive esophagogastric junctional cancer with splenic metastasis who underwent metastasectomy and obtained pathological complete response following immune checkpoint therapy and had long-term survival. We reviewed the literature to discuss the clinical significance of our treatment strategy.

Abstract
We report a case of pembrolizumab therapy as the fourth-line therapy for colorectal cancer and multiple lymph node recurrence with high-frequency microsatellite instability(MSI-High). The patient was a 75-year-old woman diagnosed with ascending colon cancer(pT4aN2bM0, Stage Ⅲc)and underwent laparoscopic right hemicolectomy, D3 dissection, and functional end-to-end anastomosis after inserting a self-expandable metallic stent. Postoperative adjuvant chemotherapy was performed, and the patient was followed. Postoperative 1 year 8 months, lymph node recurrence was indicated, and FOLFOX plus panitumumab therapy was introduced. FOLFIRI plus ramucirumab therapy and FTD/TPI were introduced as the second-line and third-line treatments, respectively; however, recurrent lymph nodes were further exacerbated and showed treatment resistance. Lymph node biopsy confirmed MSI-High, and pembrolizumab therapy was initiated as the fourth-line treatment. After the therapy, the lymph nodes reduced markedly. The patient remains undergoing chemotherapy without any adverse events.

Abstract
BACKGROUND Preserved ratio impaired spirometry (PRISm) is a common spirometry finding, but its heterogeneous manifestations and frequent transitions to airflow limitation (AFL), chronic obstructive pulmonary disease, or normal spirometry hinder establishing an appropriate management strategy. This study examined whether transition to AFL and baseline comorbidities are more frequent in subjects with definite PRISm (PRISm confirmed on both current and past two spirometry tests) versus incident PRISm (PRISm confirmed only on a current test with past normal spirometry records) than in normal spirometry. METHODS Archived medical check-up data of subjects aged ≥40 years (n = 10828) with two past spirometry records, in a Japanese hospital, were cross-sectionally analyzed. Among them, data from those with follow-up spirometry after three years (n = 6467) were used to evaluate transition to AFL. PRISm was defined as forced volume in 1 s (FEV1)/forced vital capacity ≥0.7 and % predicted FEV1 < 80%. RESULTS Overall PRISm prevalence was 6.5%. In multivariable models adjusted for age, sex, smoking status, and body mass index, definite PRISm (n = 290), but not incident PRISm (n = 183), was associated with elevated hemoglobin A1c and C-reactive protein levels, and higher rates of asthma, hypertension, hyperlipidemia, and diabetes than was consistent normal spirometry (n = 9694). The transition to AFL after three years was more frequent in definite PRISm, but not incident PRISm, than in normal spirometry (adjusted hazard ratio [95% confidence interval] = 6.21 [3.42-10.71] and 1.45 [0.23-4.73], respectively). CONCLUSIONS Multiple confirmed PRISm on past and baseline spirometry is closely associated with metabolic syndrome factors, asthma history, and future AFL development.

Abstract
The cDNA library prepared from Lentinula edodes, Hokken 600 (H600), primordia was screened using cDNA expressed specifically in Dictyostelium discoideum prestalk as a probe. Twenty-one clones, Le-Dd1 ~ 21, were isolated from the L. edodes primordia cDNA library. Functional analysis of each gene was carried out by transformation into protoplast cells from L. edodes Mori 252 (M252) mycelia with the overexpression vector pLG-RasF1 of each gene because M252 protoplast cells were transformed with an 11-fold higher efficiency than H600 cells. Transformants with the overexpression vector of Le-Dd10 formed a fruiting body at almost the same time as H600, a positive control, although M252, a negative control, did not form a fruiting body under culture conditions. This suggested that Le-Dd10 is involved in the formation of fruiting bodies. Single-strand conformation polymorphism analysis revealed that Le-Dd10 is located on No. 4 linkage group of L. edodes. The properties of Le-Dd10 products were investigated by Western blotting analysis using polyclonal antibodies against GST:Le-Dd10 fusion proteins. As a result, 56-kDa, 27-kDa, and 14-kDa protein bands appeared in primordial and fruiting body stages, although the expected molecular weight of the Le-Dd10 product was 50 kDa.

Abstract
Continuous positive airway pressure (CPAP) therapy can be beneficial in patients with obstructive sleep apnea (OSA) and cardiovascular diseases, reducing arrhythmia frequency and improving cardiac function. We describe a case of moderate OSA with idiopathic dilated cardiomyopathy, in which the frequency of premature ventricular contraction (PVC) and non-sustained ventricular tachycardia (NSVT) increased immediately after initiating CPAP therapy. Although PVC and NSVT are benign cardiac arrhythmias, they are associated with an increased risk of sustained lethal ventricular tachyarrhythmias. Therefore, when initiating CPAP therapy, the possibility of increased arrhythmia should be considered.

Abstract
STUDY OBJECTIVES Since subjective sleep duration (SSD) is considered to be longer than objective sleep duration (OSD), results of SSD minus OSD (SSD-OSD) might always be thought to be positive. Some recent reports showed different results, but exact results have not been obtained. The difference between SSD and OSD may change according to OSD. We investigated this difference and its association with sleep-disordered breathing (SDB) or nonrestorative sleep. METHODS This cross-sectional study evaluated 6,908 community residents in Nagahama, Japan. SSD was determined by self-administered questionnaire. OSD was measured by wrist actigraphy and sleep diary. SDB was assessed according to the 3% oxygen desaturation index adjusted for OSD. RESULTS Worthy of notice was that SSD was shorter than OSD for those with SSD longer than 6.98 hours in all participants, 7.36 hours in males, and 6.80 hours in females. However, SSD was longer than OSD (mean ± SD: 6.49 ± 1.07 vs 6.01 ± 0.96; P < .001) overall, as SSD is considered to be longer than OSD. In patients with SDB, the difference between SSD-OSD was greater when OSD was shorter. The difference also depended on SDB severity. The degree of positivity between OSD and SSD was a significant factor in nonrestorative sleep (odds ratio: 2.691; P < .001). CONCLUSIONS When OSD was slightly less than 7 (6.98) hours, participants reported or perceived SSD > OSD. When OSD was > 6.98 hours, participants reported or perceived SSD < OSD. Patients with SDB reported longer SSD than OSD according to severity of SDB. Evaluating SSD, OSD, and their differences may be useful for managing sleep disturbances, including nonrestorative sleep.

Abstract
Background Ventilatory management of respiratory failure with pneumomediastinum/subcutaneous emphysema is not established. Herein, we report a case of severe COVID-19 pneumonia with extensive pneumomediastinum/subcutaneous emphysema, rescued by thorough lung-protective ventilatory management after applying the VV-ECMO. Case presentation A 68-year-old male with no medical history was admitted to a local hospital and diagnosed with COVID-19 pneumonia. His pulmonary parameters worsened during invasive ventilation due to the development of pneumomediastinum/subcutaneous emphysema, and then he was transferred to our hospital. On arrival, we immediately decided to apply VV-ECMO and switch to ultraprotective ventilation. After maintaining the initial ventilation with a neuromuscular blocking agent for 2 days, we gradually increased PEEP while limiting PIP to 25 cmH2O. The patient was weaned off VV-ECMO on day 10; he was transferred to the medical ward after extubation. Conclusions Lung-protective ventilatory management should be performed thoroughly during VV-ECMO in severe COVID-19 pneumonia with pneumomediastinum/subcutaneous emphysema.

Abstract
The prevalence of sleep disordered breathing (SDB) is reportedly very high. Among SDBs, the incidence of obstructive sleep apnea (OSA) is higher than previously believed, with patients having moderate-to-severe OSA accounting for approximately 20% of adult males and 10% of postmenopausal women not only in Western countries but also in Eastern countries, including Japan. Since 1998, when health insurance coverage became available, the number of patients using continuous positive airway pressure (CPAP) therapy for sleep apnea has increased sharply, with the number of patients about to exceed 500,000 in Japan. Although the "Guidelines for Diagnosis and Treatment of Sleep Apnea Syndrome (SAS) in Adults" was published in 2005, a new guideline was prepared in order to indicate the standard medical care based on the latest trends, as supervised by and in cooperation with the Japanese Respiratory Society and the "Survey and Research on Refractory Respiratory Diseases and Pulmonary Hypertension" Group, of Ministry of Health, Labor and Welfare and other related academic societies, including the Japanese Society of Sleep Research, in addition to referring to the previous guidelines. Because sleep apnea is an interdisciplinary field covering many areas, this guideline was prepared including 36 clinical questions (CQs). In the English version, therapies and managements for SAS, which were written from CQ16 to 36, were shown. The Japanese version was published in July 2020 and permitted as well as published as one of the Medical Information Network Distribution Service (Minds) clinical practice guidelines in Japan in July 2021.

Abstract
Background Home monitoring devices have been developed to measure adherence to home oxygen therapy. In this study, we evaluated the performance of TeleOx®, a commercially available remote monitoring device, in comparison with polysomnography (PSG) in patients with interstitial lung disease (ILD) and chronic obstructive pulmonary disease (COPD) and the factors that affected TeleOx® correct use. Methods TeleOx® was connected on the patient or concentrator side. The oxygen flow rates were set at 1, 3, and 5 L/min. Intraclass correlation coefficient (ICC) (2,1) was used to determine the agreement between respiratory rate measured using TeleOx® and that measured using PSG, and the minimum acceptable level of reliability was >0.7. Results In total, 22 patients (16 with ILD and 6 with COPD) were assessed. In patients with ILD, the detection rate of patients' respiration assessed using TeleOx® did not change according to the device's position. It increased from 53.5% to 79.0% by changing the position from the concentrator to the patient side in patients with COPD. The ICC (2,1) value indicated that TeleOx® had acceptable reliability at oxygen flow rates of 1 and 3 L/min regardless of the device's position in patients with ILD (the concentrator side: 0.9 and 0.82, respectively; the patient side: 0.95 and 0.82, respectively), whereas that did only at the oxygen flow rate of 1 L/min and in connecting TeleOx® on the patient side in patients with COPD (0.73). Conclusion The monitoring performance of TeleOx® differed according to its position, oxygen flow rates, and patients' diseases.

Abstract
KEYNOTE-158 and 061 trials revealed the efficacy and safety of pembrolizumab(KEYTRUDA®)treatment in patients with recurrent high microsatellite instability(MSI-high)gastric cancer following gastrectomy. Here, we successfully treated an elderly case with recurrences following radical gastrectomy for advanced gastric cancer using pembrolizumab as a second- line chemotherapy. Even in elderly patients, pembrolizumab might contribute to effective and safe treatment in late-line chemotherapy for recurrent MSI-high gastric cancer.

Abstract
Plants employ two different types of immune receptors, cell surface pattern recognition receptors (PRRs) and intracellular nucleotide-binding and leucine-rich repeat-containing proteins (NLRs), to cope with pathogen invasion. Both immune receptors often share similar downstream components and responses but it remains unknown whether a PRR and an NLR assemble into the same protein complex or two distinct receptor complexes. We have previously found that the small GTPase OsRac1 plays key roles in the signaling of OsCERK1, a PRR for fungal chitin, and of Pit, an NLR for rice blast fungus, and associates directly and indirectly with both of these immune receptors. In this study, using biochemical and bioimaging approaches, we revealed that OsRac1 formed two distinct receptor complexes with OsCERK1 and with Pit. Supporting this result, OsCERK1 and Pit utilized different transport systems for anchorage to the plasma membrane (PM). Activation of OsCERK1 and Pit led to OsRac1 activation and, concomitantly, OsRac1 shifted from a small to a large protein complex fraction. We also found that the chaperone Hsp90 contributed to the proper transport of Pit to the PM and the immune induction of Pit. These findings illuminate how the PRR OsCERK1 and the NLR Pit orchestrate rice immunity through the small GTPase OsRac1.

Abstract
Remdesivir, a prodrug of the nucleoside analog GS‐441524, plays a key role in the treatment of coronavirus disease 2019 (COVID‐19). However, owing to limited information on clinical trials and inexperienced clinical use, there is a lack of pharmacokinetic (PK) data in patients with COVID‐19 with special characteristics. In this study, we aimed to measure serum GS‐441524 concentrations and develop a population PK (PopPK) model. Remdesivir was administered at a 200 mg loading dose on the first day followed by 100 mg from day 2, based on the package insert, in patients with an estimated glomerular filtration rate (eGFR) greater than or equal to 30 ml/min. In total, 190 concentrations from 37 Japanese patients were used in the analysis. The GS‐441524 trough concentrations were significantly higher in the eGFR less than 60 ml/min group than in the eGFR greater than or equal to 60 ml/min group. Extracorporeal membrane oxygenation in four patients hardly affected the total body clearance (CL) and volume of distribution (Vd) of GS‐441524. A one‐compartment model described serum GS‐441524 concentration data. The CL and Vd of GS‐441524 were significantly affected by eGFR readjusted by individual body surface area and age, respectively. Simulations proposed a dose regimen of 200 mg on day 1 followed by 100 mg once every 2 days from day 2 in patients with an eGFR of 30 ml/min or less. In conclusion, we successfully established a PopPK model of GS‐441524 using retrospectively obtained serum GS‐441524 concentrations in Japanese patients with COVID‐19, which would be helpful for optimal individualized therapy of remdesivir.

Abstract
STUDY OBJECTIVES Whether the association between sleep-disordered breathing (SDB) and cardiovascular disease (CVD) is independent of comorbid risk factors for CVD is controversial. The objective of this study is to elucidate whether the association between SDB severity and the surrogate markers of CVD evets differs in relation to the number of comorbidities. METHODS This cross-sectional study included 7731 participants. Severity of SDB was determined by the oxygen desaturation index adjusted by actigraph-measured objective sleep time. Participants were stratified according to SDB severity and the number of comorbidities (hypertension, diabetes, dyslipidemia and obesity), and the associations between the maximum value of intima-media thickness of the common carotid artery (CCA-IMT-max), brachial-ankle pulse wave velocity (baPWV) and cardio-ankle vascular index (CAVI) were evaluated. RESULTS Among participants with no risk factor, CCA-IMT-max increased according to SDB severity (n = 1022, P <0.0001). Even after the matching of background, the median CCA-IMT-max value was 14% higher in moderate-severe SDB cases than those without SDB (n=45 in each group, P=0.020). The difference was not significant for baPWV and CAVI. On the other hand, a significant difference in CCA-IMT-max was not found in those with multiple comorbidities. Consistently, multiple regression analysis revealed an independent association between CCA-IMT-max and moderate-severe SDB for all study participants (β: 0.0222 (95% confidence interval: 0.0039-0.0405), P=0.017), but the association was not significant for stratified participants with multiple comorbidities. CONCLUSIONS SDB severity is associated with the CCA-IMT-max level, but the independent association becomes weaker for those with multiple comorbidities.

Abstract
STUDY OBJECTIVES It is well known that a family history of diabetes (FHD) is a definitive risk factor for type 2 diabetes. It has not been known whether sleep-disordered breathing (SDB) increases the prevalence of diabetes in those with an FHD. METHODS We assessed SDB severity in 7,477 study participants by oximetry corrected by objective sleep duration determined by wrist actigraphy. Glycated hemoglobin ≥6.5% and/or current medication for diabetes indicated the presence of diabetes. In addition to the overall prevalence, the prevalence of recent-onset diabetes during the nearly 5 years before the SDB measurements were made was investigated. RESULTS Of the 7,477 participants (mean age: 57.9; range: 34.2-80.7; SD: 12.1 years; 67.7% females), 1,569 had an FHD. The prevalence of diabetes in FHD participants with moderate-to-severe SDB (MS-SDB) was higher than in those without SDB (MS-SDB vs without SDB: all, 29.3% vs 3.3% [P < .001]; females, 32.6% vs 1.9% [P < .001]; males, 26.2% vs 11.7% [P = .037]). However, multivariate analysis showed that MS-SDB was significantly associated with a higher prevalence of diabetes only in FHD-positive females (odds ratio [95% confidence interval]: females, 7.43 [3.16-17.45]; males, 0.92 [0.37-2.31]). Among the FHD-positive participants, the prevalence of recent-onset diabetes was higher in those with MS-SDB than those without SDB, but only in females (MS-SDB vs without SDB: 21.4% vs 1.1%; P < 0.001). CONCLUSIONS MS-SDB was associated with diabetes risk in females with an FHD, and future studies are needed on whether treatment of SDB in females with an FHD would prevent the onset of diabetes.

Abstract
Severe post-transplant hypoxemia, which is defined as <50 mm Hg of the partial pressure of oxygen in arterial blood/fraction of inspired oxygen (P/F) ratio, is a major post-operative complication with high mortality rates in patients with hepatopulmonary syndrome (HPS). Non-invasive positive pressure ventilation therapy and mechanical ventilation are options for respiratory support of patients with severe post-transplant hypoxemia. However, these therapies are associated with several problems, such as compliance, ventilator-associated pneumonia, and lung injury. We here firstly described two children with HPS who developed severe post-transplant hypoxemia (lowest post-operative P/F ratio, 49.7 and 34.0 mm Hg, respectively) that was successfully managed with high-flow nasal cannula (HFNC) oxygen therapy and vasodilation drugs without adverse complications or necessity of reintubation. We consider that HFNC oxygen therapy could become a safe alternative respiratory therapy or be added to the other such as inhaled nitric oxide (iNO), methylene blue (MB), inhaled epoprostenol, embolization of abnormal pulmonary vessels, and combination of iNO and MB for severe post-transplant hypoxemia in children with HPS.

Abstract
Postoperative low nutrition, body weight loss and poor QOL are pivotal clinical issues for elderly patients following total gastrectomy for advanced gastric cancer. Here, we report a successfully treated high-risk elderly case using home night enteral nutrition and adjuvant chemotherapy following laparoscopic total gastrectomy for advanced gastric cancer. Home night enteral nutrition might not impair oral intake and daily QOL, and could be a useful treatment strategy for elderly patients following total gastrectomy.

Abstract
Abstract
Background
The diagnosis of acute (AM) is difficult because of the variable, unspecific clinical presentation. Cardiac magnetic resonance (CMR) is the noninvasive gold standard diagnostic tool, but limited availability and high costs make a quick and inexpensive test necessary to clarify the need for CMR. Quantification of high sensitive Troponin T (hsTNT) is a broadly available, specific blood test for cardiomyocyte damage.
Aim
The aim of this study was to evaluate hsTNT as a gatekeeper for CMR with a lower cut off-value for exclusion and an upper cut-off value for confirmation of acute myocarditis as defined by CMR.
Methods
This retrospective analysis included 244 patients (age 39±17 years, 71% male) who received CMR for clinically suspected AM and quantification of hsTNT within 28 days (Median: 2 days) of CMR. CMR (1.5 Tesla) consisted of cine-sequences, edema-sensitive T2 and late gadolinium enhancement (LGE) imaging. AM was diagnosed in presence of both, myocardial edema and LGE consistent with acute myocarditis.
Results
Of 244 patients, 78 (32%) were CMR-positive (CMR+) for AM. 166 (68%) were CMR negative (CMR−). Mean hsTNT was 206±454 pg/ml.
HsTNT was significantly higher in CMR+ than in CMR− (604±639 pg/ml vs 20±56 pg/ml, p<0.001, see figure A). 8 CMR+ patients (10%) had hsTNT in the normal range (<14 ng/ml).
HsTNT showed good discriminatory performance in the Receiver Operator Characteristic (ROC) analysis (AUC 0.91, see figure B).
A lower cut-off value of 4 pg/ml had a sensitivity of 98.7% for diagnosis of AM (hsTNT ≥4 pg/ml) and a negative predictive value of 98.2% for rule out of AM (hsTNT<4 pg/ml) as defined by CMR, leading to a reduction of 23.4% of CMR exams. An upper cut-off value of >343 pg/ml had a specificity of 99.4% and positive predictive value of 97.8% for diagnosis of AM, leading to a reduction of 18.4% of CMR exams (see table).
Conclusions
hsTNT showed good discriminatory capacity for acute myocarditis (AM) as defined by CMR. However, 10% of patients had hsTNT in the normal range (<14 pg/ml). A lower cut-off value of <4 pg/ml ruled out AM with very high negative predictive value, whereas an upper cut-off of >343 pg/ml had a very high positive predictive value for confirmation of AM as defined by CMR. Performing CMR only in patients with hsTNT between 4 and 343 pg/ml would have led to a reduction of 41.8% of CMR exams.
