    Abstract

    Radiation therapy (RT) can enhance the abscopal effect of immune checkpoint blockade. This phase I/II study investigated the efficacy and safety of nivolumab plus RT in HER2-negative metastatic breast cancer requiring palliative RT for bone metastases. Cohort A included luminal-like disease, and cohort B included both luminal-like and triple-negative disease refractory to standard systemic therapy. Patients received 8 Gy single fraction RT for bone metastasis on day 0. Nivolumab was administered on day 1 for each 14-day cycle. In cohort A, endocrine therapy was administered. The primary endpoint was the objective response rate (ORR) of the unirradiated lesions. Cohorts A and B consisted of 18 and 10 patients, respectively. The ORR was 11% (90% CI 4–29%) in cohort A and 0% in cohort B. Disease control rates were 39% (90% CI 23–58%) and 0%. Median progression-free survival was 4.1 months (95% CI 2.1–6.1 months) and 2.0 months (95% CI 1.2–3.7 months). One patient in cohort B experienced a grade 3 adverse event. Palliative RT combined with nivolumab was safe and showed modest anti-tumor activity in cohort A. Further investigations to enhance the anti-tumor effect of endocrine therapy combined with RT plus immune checkpoint blockade are warranted.

    BACKGROUND/PURPOSE: This prospective study aimed to investigate the dynamic changes in the gut microbiota (GM) and associated intestinal environment, which were assessed by measuring fecal organic acid (OA) concentrations, during the early period after liver transplantation (LT). To understand the fundamental characteristics of the human GM, data obtained from living donors were also analyzed. METHODS: Fixed-point observation was performed in 23 recipients and 21 donors for up to 2 weeks after LT. The GM and OA concentrations were investigated using ribosomal RNA-targeted reverse-transcription quantitative polymerase chain reaction and high-performance liquid chromatography, respectively. RESULTS: Before LT, the recipients exhibited remarkable dysbiosis and OA depletion, which were proportional to the model for end-stage liver disease score. Correlations between the abundances of some specific strains and OA concentrations were observed. After LT, while donor lobectomy caused only slight, transient and reversible changes in the GM and OA concentrations, recipients exhibited delayed recovery in these factors. However, no clear evidence of causality was observed between the GM or OA concentrations and LT outcomes. CONCLUSIONS: The GM and intestinal environment in LT recipients exhibited characteristics that were clearly different from those in donors. LT did not normalize but rather disrupted the GM during the early post-LT period, but its negative clinical impact could be minimized with perioperative management.

    INTRODUCTION: The nonexposed variant of antiresorptive agent-related osteonecrosis of the jaw (ARONJ) presents with nonspecific clinical findings. The diagnosis of nonexposed ARONJ poses a critical challenge, and there is little evidence regarding its treatment and outcomes. This study aimed to examine the clinical outcomes in patients with nonexposed antiresorptive agent-related osteomyelitis of the jaw (AROMJ). The terms ARONJ and AROMJ were used separately in this study. MATERIALS AND METHODS: We enrolled patients with nonexposed AROMJ (osteomyelitis of the jaw without bone exposure associated with antiresorptive agents) with partial reference to an existing position paper on ARONJ. The initiating event of osteomyelitis was limited to periodontitis. Based on the findings of bone scintigraphy, panoramic radiography, computed tomography, and histopathological examination, we also used the hierarchical diagnostic criteria (HDC) for osteomyelitis of the jaw. RESULTS: There were 58 confirmed cases of nonexposed AROMJ based on the HDC. All patients had sufficient clinical findings to be diagnosed with nonexposed AROMJ as osteomyelitis underwent extraction with bone debridement. The healing rate was 93.1% (54/58). Univariable analysis showed a strong association between the healing status and malignant disease, while multivariable analysis showed no strong association between them. CONCLUSIONS: The present study had a relatively large sample size of patients with nonexposed AROMJ. The primary disease in patients with nonexposed AROMJ may not have a strong association with the healed status of the lesion. Based on its high healing rate, extraction with bone debridement in confirmed nonexposed AROMJ may prevent progression.

    Rationale: There is a growing need to accurately estimate the prognosis of idiopathic pulmonary fibrosis (IPF) in clinical practice, given the development of effective drugs for treating IPF. Objectives: To develop artificial intelligence-based image analysis software to detect parenchymal and airway abnormalities on computed tomographic (CT) imaging of the chest and to explore their prognostic importance in patients with IPF. Methods: A novel artificial intelligence-based quantitative CT image analysis software (AIQCT) was developed by applying 304 high-resolution CT (HRCT) scans from patients with diffuse lung diseases as the training set. AIQCT automatically categorized and quantified 10 types of parenchymal patterns as well as airways, expressing the volumes as percentages of the total lung volume. To validate the software, the area percentages of each lesion quantified by AIQCT were compared with those of the visual scores using 30 plain high-resolution CT images with lung diseases. In addition, three-dimensional analysis for similarity with ground truth was performed using HRCT images from 10 patients with IPF. AIQCT was then applied to 120 patients with IPF who underwent HRCT scanning of the chest at our institute. Associations between the measured volumes and survival were analyzed. Results: The correlations between AIQCT and the visual scores were moderate to strong (correlation coefficient 0.44-0.95) depending on the parenchymal pattern. The Dice indices for similarity between AIQCT data and ground truth were 0.67, 0.76, and 0.64 for reticulation, honeycombing, and bronchi, respectively. During a median follow-up period of 2,184 days, 66 patients died, and 1 underwent lung transplantation. In multivariable Cox regression analysis, bronchial volumes (adjusted hazard ratio [HR], 1.33; 95% confidence interval [CI], 1.16-1.53) and normal lung volumes (adjusted HR, 0.97; 95% CI, 0.94-0.99) were independently associated with survival after adjusting for the gender-age-lung physiology stage of IPF. Conclusions: Our newly developed artificial intelligence-based image analysis software successfully quantified parenchymal lesions and airway volumes. Bronchial and normal lung volumes on HRCT imaging of the chest may provide additional prognostic information on the gender-age-lung physiology stage of IPF.

    BACKGROUND: The standard treatment for unresectable advanced/recurrent esophageal cancer in Japan is 5-fluorouracil plus platinum-containing drugs as first-line chemotherapy and taxanes as second-line chemotherapy. However, the standard regimen after patients become refractory to these treatments remains to be established. Therefore, we investigated the efficacy of trifluridine/tipiracil (FTD/TPI) in patients with esophageal cancer who are refractory or intolerant to 5-fluorouracil, platinum-containing drugs, and taxanes. METHODS: This single-arm phase II trial was conducted in seven hospitals in Japan. Eligible patients were those with unresectable advanced/recurrent esophageal cancer that was refractory or intolerant to 5-fluorouracil, platinum-containing drugs, and taxanes. The primary endpoint was the 3-month progression-free survival rate, and the secondary endpoints were the 6-month progression-free survival rate, progression-free survival, overall survival, response rate, disease control rate, and toxicity. RESULTS: Forty-two patients were enrolled between October 2015 and June 2016. All tumors were squamous cell carcinomas. The progression-free survival rates at 3 and 6 months were 15.4% (90% confidence interval 7.4-26.0%) and 7.7% (90% confidence interval 2.6-16.6%), respectively. The median progression-free survival and median overall survival were 1.3 (95% confidence interval 1.0-1.8) months and 4.5 (95% confidence interval 3.6-5.7) months, respectively. The response rate was 0%, and the disease control rate was 23.8% (95% confidence interval 13.5-38.5%). The major grade 3/4 toxicities were neutropenia (47.6%), leukocytopenia (35.7%), and anemia (21.4%). No treatment-related deaths occurred. Exploratory subgroup analyses showed better progression-free survival in the subgroup without distant metastasis at diagnosis. CONCLUSIONS: Trifluridine/tipiracil monotherapy is feasible and shows modest activity in patients with refractory esophageal squamous cell carcinoma.

    Choking can lead to mortality and residual impairments. This study aimed to determine the factors associated with choking among acute hospital patients and examine error-producing conditions to suggest choking-prevention policies. Among 36,364 cases reported by hospital staff at an acute university hospital from 2012 to 2018 were examined using a retrospective study, 35,440 were analysis as the number of cases analysed for the study. We used descriptive statistics to present patient characteristics and conducted univariable and multivariable logistic regression analyses to identify factors associated with choking. Additionally, we conducted content analysis (root cause analysis) to examine error-producing conditions and prevention policies. Sixty-eight cases were related to choking injuries; of these, 43 patients (63.2%) were male, and 38 (55.9%) were aged 65 years and older. Choking cases had a high percent of adverse outcomes involving residual impairment or death (n = 23, 33.8%). Mental illness (adjusted odds ratio [95% confidence interval]: 3.14 [1.39-7.08]), and hospitalisation in the general wards (adjusted odds ratio [95% confidence interval]: 3.13 [1.70-5.76]) were associated with an increased probability of choking. Error production was caused by food (n = 25, 36.8%) and medical devices or supplies (n = 13, 19.1%). Almost all contributory factors were associated with inadequate checking (n = 66, 97.1%) and misperception of risk (n = 65, 95.6%). Choking poses a highly significant burden on patients, and hospital administrators should minimise the risk of choking to prevent related injuries. Hospital administrators should provide training and education to their staff and develop adequate protocols and procedures to prevent choking.

    BACKGROUND: The management of anxiety and depression symptoms in rheumatoid arthritis (RA) patients is vital. Previous study findings on this topic are conflicting, and the topic remains to be thoroughly investigated. This study aimed to clarify the association of RA disease activity with anxiety and depression symptoms after controlling for physical disability, pain, and medication. METHODS: We conducted a cross-sectional study of RA patients from the XXX Rheumatoid Arthritis Management Alliance cohort. We assessed patients using the Disease Activity Score (DAS28), Health Assessment Questionnaire Disability Index (HAQ-DI), and Hospital Anxiety and Depression Scale (HADS). Anxiety and depression symptoms were defined by a HADS score ≥ 8. We analyzed the data using multivariable logistic regression analyses. RESULTS: Of 517 participants, 17.6% had anxiety symptoms and 27.7% had depression symptoms. The multivariable logistic regression analysis demonstrated that DAS28 was not independently associated with anxiety symptoms (odds ratio [OR] [95% confidence interval; CI] 0.93 [0.48-1.78]; p = 0.82) and depression symptoms (OR [95% CI] 1.45 [0.81-2.61]; p = 0.22). However, DAS28 patient global assessment (PtGA) severity was associated with anxiety symptoms (OR [95% CI] 1.15 [1.02-1.29]; p = 0.03) and depression symptoms (OR [95% CI] 1.21 [1.09-1.35]; p < 0.01). Additionally, HAQ-DI scores ≤ 0.5 were associated with anxiety symptoms (OR [95% CI] 3.51 [1.85-6.64]; p < 0.01) and depression symptoms (OR [95% CI] 2.65 [1.56-4.50]; p < 0.01). Patients using steroids were more likely to have depression than those not using steroids (OR [95% CI] 1.66 [1.03-2.67]; p = 0.04). CONCLUSIONS: No association was found between RA disease activity and anxiety and depression symptoms in the multivariable logistic regression analysis. Patients with high PtGA scores or HAQ-DI scores ≤ 0.5 were more likely to experience anxiety and depression symptoms, irrespective of disease activity remission status. Rather than focusing solely on controlling disease activity, treatment should focus on improving or preserving physical function and the patient's overall sense of well-being.

    OBJECTIVES: Rheumatoid arthritis (RA) is a chronic inflammatory disease characterized by localized and generalized bone loss. The risk of fractures is doubled in patients with RA. Denosumab, an anti-RANKL monoclonal antibody, is used for those with osteoporosis at high risk fracture and it has inhibitory effect of progressive bone erosion in patients with RA. While the increase in bone mineral density by denosumab has been reported in patients with RA, preventive effect of fracture by denosumab remains unknown. This study aimed to evaluate the efficacy of denosumab in treating clinical fracture risk in patients with RA. METHODS: Patients with RA who received denosumab treatment between 2013 and 2019 were retrospectively evaluated using the ANSWER (Kansai Consortium for the Well-Being of Rheumatic Disease Patients) cohort data. Fracture rates were evaluated between 0 and 6 months (reference period) versus > 6 months (post-reference period) of denosumab use. RESULTS: A total of 873 patients with RA received denosumab, and their characteristics were as follows: 88% females, mean age 68 years, and average disease duration 14.5 years. The hazard rates of all clinical fractures were 0.69 (per 100 person-years) in the reference period and 0.35 in the post-reference period, indicating a 49.2% decrease (p = 0.03). CONCLUSIONS: Denosumab suppresses the risk of clinical fractures in patients with RA.

    <sec><title>Introduction</title>Alzheimer’s disease (AD) is one of the most common causes of dementia. Pathogenic variants in the presenilin 1 (PSEN1) gene are the most frequent cause of early-onset AD. Medications for patients with AD bearing PSEN1 mutation (PSEN1-AD) are limited to symptomatic therapies and no established radical treatments are available. Induced pluripotent stem cell (iPSC)-based drug repurposing identified bromocriptine as a therapeutic candidate for PSEN1-AD. In this study, we used an enrichment strategy with iPSCs to select the study population, and we will investigate the safety and efficacy of an orally administered dose of bromocriptine in patients with PSEN1-AD.

    </sec><sec><title>Methods and analysis</title>This is a multicentre, randomised, placebo-controlled trial. AD patients with PSEN1 mutations and a Mini Mental State Examination-Japanese score of ≤25 will be randomly assigned, at a 2:1 ratio, to the trial drug or placebo group (≥4 patients in TW-012R and ≥2 patients in placebo). This clinical trial consists of a screening period, double-blind phase (9 months) and extension phase (3 months). The double-blind phase for evaluating the efficacy and safety is composed of the low-dose maintenance period (10 mg/day), high-dose maintenance period (22.5 mg/day) and tapering period of the trial drug. Additionally, there is an open-labelled active drug extension period for evaluating long-term safety. Primary outcomes are safety and efficacy in cognitive and psychological function. Also, exploratory investigations for the efficacy of bromocriptine by neurological scores and biomarkers will be conducted.

    </sec><sec><title>Ethics and dissemination</title>The proposed trial is conducted according to the Declaration of Helsinki, and was approved by the Institutional Review Board (K070). The study results are expected to be disseminated at international or national conferences and published in international journals following the peer-review process.

    OBJECTIVES: Drug-resistant overactive bladder (OAB) represents an unmet medical need in that treatment options are limited. We developed a treatment model based on cognitive behavioral therapy and evaluated its feasibility and acceptability for drug-resistant OAB in women. METHODS: This was an open-label, single-arm, multicenter pilot study. We defined drug-resistant OAB as OAB with moderate to severe symptoms despite pharmacotherapy for more than 12 weeks. A face-to-face intervention was prescribed as six sessions (30 minutes each) over 6 to 12 weeks according to a treatment manual. The effects were assessed by self-reported questionnaires and frequency voiding charts (FVC) at baseline, during intervention, immediately after intervention, and at follow-up. RESULTS: Ten patients participated in this study. Median age was 72 years, median OAB Symptom Score was nine points, and median duration of prior treatment for OAB was 5.5 years at baseline. Two participants dropped out of the study. Among the remaining patients, the scores of the OAB Questionnaire subscales improved (effect size: 0.75-1.73), and the mean urinary frequency in the FVC also improved from baseline (9.0 times, SD: 2.1) to follow-up (6.2 times, SD: 1.2). All participants were satisfied with the intervention. There were no adverse events during this study. CONCLUSIONS: The new treatment based on cognitive behavioral therapy was well tolerated and feasible in women with drug-resistant OAB. Further randomized research is needed to rigorously evaluate the efficacy of the treatment.

    Background: Advances in immuno-oncology (IO), i.e., programmed cell-death protein 1 (PD-1) inhibitors, are revolutionizing cancer treatment by offering hope for a cure. However, the benefit of IO agents in metastatic breast cancer (MBC) remains limited. For immunotherapy to be successful, it is essential to understand the tumor immune contexture. Systemic immune alterations, such as the signature of peripheral blood mononuclear cells (PBMC) and cytokine expression, are one of the hallmarks of successful immunotherapy in MBC. The abscopal effect induced by radiation therapy (RT) is known to be a modulator of systemic immune alterations, and the abscopal effect is considered as a systemic anti-tumor immune response. In this study, we integrated time series multi-omics data in order to identify alteration of the immune signatures after RT combined with nivolumab, a PD-1 inhibitor, using a longitudinal liquid biopsy with artificial intelligence. Methods: This study was conducted as translational research, part of the KBCRN-B-002 trial, which is a multicenter phase Ib/II study evaluating the safety and efficacy of nivolumab in combination with RT in patients with HER2-negative MBC (UMIN: UMIN000026046). Twenty-nine patients were included in the translational analysis set. The multi-omics data included data from RNAseq, mass cytometry (CyTOF) and multiple cytokines, using PBMC, serum and plasma. We collected time series data, which covered the baseline, two weeks after starting therapy, four weeks after starting therapy and the timing of progressive disease. For integrated analysis of the multi-omics data, a machine-learning method was developed. Results: Our integrated analysis (involving a longitudinal liquid biopsy and machine-learning method) identified an apparent cluster of responder groups and alteration of the systemic immune signatures. Single-cell analysis using CyTOF results including the signature of the immune cell composition, effector immune cells and immune suppressor cells. Conclusions: Our method clustered responders well and identified candidates of the systemic immune signatures for actionable hallmarks of RT combined with IO agent by a longitudinal liquid biopsy. Clinical trial information: NCT03430479 .

    Objectives: Sarcopenia is characterized by loss of muscle strength and mass, leading to falls and adverse health outcomes. Our aim was to determine the prevalence of sarcopenia in patients with rheumatoid arthritis (RA) and to identify factors associated with sarcopenia in these patients. Methods: A cross-sectional study of 388 consecutive women with RA was conducted, assessing muscle mass and strength, and walking speed. Falls and bone fractures sustained over the prior year were evaluated. The association between sarcopenia and RA characteristics, falls, and bone fractures was evaluated using logistic regression analyses. Results: The prevalence of sarcopenia was 37.1% (14.7%, severe sarcopenia; 22.4%, sarcopenia), with 49.0% classified as having low muscle mass. The incidence of falls, fractures, and lower bone mineral density was higher in patients with than without sarcopenia. Age, RA duration, Steinbrocker's stage, the high Mini-Nutritional Assessment-Short Form score and the use of biological disease-modifying anti-rheumatic drugs (bDMARDs) were independent factors associated with sarcopenia. Conclusion: We confirmed that sarcopenia develops in a significant proportion of patients with RA. Age, longer disease duration, joint destruction and malnutrition were positively associated with sarcopenia, with the use of bDMARDs being negatively associated.

    Rheumatoid arthritis (RA) patients often have altered body composition including reduced muscle mass and increased fat mass. Some RA patients are likely to increase visceral fat without obesity [Body Mass Index (BMI) ≥ 25]. The objective of the study was to determine the association between obesity and/or visceral adiposity and the risk for atherosclerosis in Japanese RA patients. Obesity was evaluated using the BMI, with visceral adiposity evaluated using the visceral fat area (VFA) and the visceral/subcutaneous fat ratio (V/S ratio), quantified using the dual bioelectrical impedance method. Atherosclerosis was evaluated based on the intima-media thickness (IMT) and Plaque score (PS) of the carotid artery, measured using ultrasonography. Multivariate analysis was performed to determine the factors associated with IMT and PS. IMT and PS were compared among groups of patients sub-classified according to BMI and VFA levels. The V/S ratio was higher in RA patients than healthy controls, after adjustment for age, BMI, and waist circumference. On multivariate analysis, the V/S ratio, but not the BMI, was independently associated with the IMT and PS. Among the sub-classifications for BMI and VFA, non-obese patients with a high visceral adiposity (18.5 ≤ BMI < 25 kg/m2 and VFA ≥ 100 cm2) had the highest IMT (mean IMT, 0.93 ± 0.29 mm; maximum IMT, 1.44 ± 0.71 mm) and PS (1.43 ± 0.61), compared to all other BMI and VFA subgroups. RA patients have increased visceral adiposity, which is associated with a high prevalence of atherosclerotic of plaques. Non-obese RA patients who have visceral adiposity have a specifically higher risk for atherosclerosis.

    BACKGROUND: Clinical remission can be maintained after the discontinuation of biological disease-modifying antirheumatic drugs (bDMARDs) in some patients with rheumatoid arthritis (RA) (bDMARD-free remission (BFR)). It is unknown which bDMARD is advantageous for achieving BFR or under which conditions BFR can be considered. This study aimed to determine the factors associated with BFR achievement in clinical practice. METHODS: Patients with RA were enrolled from a Japanese multicenter observational registry. Patients with RA who achieved clinical remission (Disease Activity Score 28-C-reactive protein < 2.3) at the time of bDMARD discontinuation were included. Serial disease activities and treatment changes were followed up. BFR was considered to have failed if the disease activity exceeded the remission cutoff value or if bDMARDs were restarted. RESULTS: Overall, 181 RA patients were included. BFR was maintained in 21.5% of patients at 1 year after bDMARD discontinuation. BFR was more successfully achieved after discontinuation of anti-tumor necrosis factor (TNF) monoclonal antibodies (TNFi(mAb)) (infliximab, adalimumab, and golimumab), followed by CTLA4-Ig (abatacept), soluble TNF receptor or Fab fragments against TNF fused with polyethylene glycol (etanercept and certolizumab), and anti-interleukin-6 receptor Ab (tocilizumab). After multivariate analysis, sustained remission (> 6 months), Boolean remission, no glucocorticoid use at the time of bDMARD discontinuation, and use of TNFi(mAb) or CTLA4-Ig remained as independent factors associated with BFR. CONCLUSIONS: BFR can be achieved in some patients with RA after bDMARD discontinuation in clinical practice. Use of TNFi(mAb) or CTLA4-Ig, sustained remission, Boolean remission, and no glucocorticoid use at the time of bDMARD discontinuation are advantageous for achieving BFR.

    Purpose: The aim of this study was to examine and compare morphological and functional outcomes after either isolated mandibular setback or bimaxillary surgery in males and females. Materials and methods: A retrospective study was done on 52 patients, in whom surgical correction for mandibular prognathism was performed either by isolated mandibular setback (30 cases) or by bimaxillary surgery (22 cases). Morphological changes were studied using cephalograms and functional changes studied using impulse oscillometry (IOS) taken before surgery (T0), 3 months (T1) and 1 year after surgery (T2). Also 3% oxygen desaturation index (ODI) was measured at T0 and T2. Result: Posterior airway space decreased significantly in both groups and both sexes but more so in males after mandibular setback surgery and in females after bimaxillary surgery. Changes in supine R20 (central airway resistance at 20 Hz) and supine R5 (total airway resistance at 5 Hz) in IOS statistically significantly increased in the period T0–T1 in males compared with females after mandibular setback surgery (p &lt
    0.05). Conclusion: Gender dimorphism is present according to morphological and functional outcomes, with males at a higher risk for obstructive sleep apnea (OSA) after mandibular setback surgery and females after bimaxillary surgery
    however, compensatory changes act as a barrier against this.

    Background Portal hypertension (PHT) is defined as a portal venous pressure gradient (PVPG) exceeding 5 mm Hg, which results in severe clinical manifestations. However, the validity of intraoperative PVPG monitoring and the association between PHT and bacterial translocation after liver transplantation remain unclear. Methods In this retrospective study, 223 patients who underwent primary adult-to-adult living donor liver transplantation from 2008 to 2015 were divided into 2 groups based on the PVPG at the end of the operation: high PVPG (&gt
    5 mm Hg, n = 69) and low PVPG (≤5 mm Hg, n = 154). The clinical factors were compared between the groups, and the association between a high PVPG and posttransplant bacteremia/bacterial infections was investigated. Results The high PVPG group had a significantly higher incidence of bacteremia (46% vs 24%, P &lt
    0.001), higher 90-day mortality rate (20% vs 7%, P = 0.002), and poorer 1-year survival (71% vs 86%, P = 0.006). The high PVPG group had a particularly higher incidence of bacteremia caused by "gut bacteria" including Enterobacteriaceae, Bacteroides spp., and Enterococcus spp. (29% vs 12%, P = 0.003). Multivariate analysis showed that a PVPG greater than 5 mm Hg (odds ratio, 2.55
    95% confidence interval, 1.18-5.55
    P = 0.017) was an independent predictor of bacteremia due to gut bacteria. Conclusions Monitoring of the PVPG is clinically meaningful for predicting patients' prognosis. In particular, a high PVPG with a threshold of 5 mm Hg at the end of adult-to-adult living donor liver transplantation may increase gut-related bacteremia through the mechanism of bacterial translocation, resulting in early mortality.

    Background: Recently, numerous pharmaceutical sponsors have expressed a great deal of interest in the development of biosimilars, which requires clinical trials to demonstrate that the pharmacokinetic (PK) and clinical efficacy are equivalent. Pharmacodynamics (PD) may be used in evaluating efficacy if there are relevant PD markers available. However, in their absence, it is necessary to design the associated clinical trials to include efficacy measures as the primary endpoint.
    Methods: In this study, we propose a novel adaptive seamless PK and efficacy design with an efficient framework to remedy the risk of misspecification of efficacy parameters and to discontinue the trial evaluating the efficacy for futility based on the PK evaluation. Here, we consider the clinical development of biosimilars including their evaluation in patients rather than healthy volunteers under a situation where both PK and efficacy parameters are required to demonstrate equivalence. The original idea of the proposed method was to organize a clinical trial that includes the statistical analysis of PK as an interim analysis, with sample size recalculation of the efficacy data.
    Results: Our simulation study indicated that the proposed design would allow trials to be more efficient than with the classical design.
    Conclusions: This proposal provides appealing advantages, such as a shorter time period, additional cost savings, and a smaller number of patients required.

    Background. In rectal cancer, anastomotic leakage was reported to have a negative impact on both short and long-term outcomes. However, there is limited data on the impact of anastomotic leakage on oncologic outcomes in patients with colon cancer. We aimed to evaluate the impact of anastomotic leakage on disease recurrence and long-term survival after curative resection of colon cancer.
    Methods. This multicenter; retrospective cohort study of 4, 919 consecutive patients utilized data from the Japanese Society for Cancer of the Colon and Rectum. Multivariable Cox regression analysis was used to adjust for confounding
    Results. The incidence of anastomotic leakage was 2.5 % and 30-day mortality was 0.21 %. The 5-year overall survival rate was 80.8% in the anastomotic leakage group, compared with 90.3% in the no leak group (P =.001). In the multivariable analysis, anastomotic leakage was significantly associated with reduced overall survival rate (hazard ratio = 1.84; 95 % confidence interval, 1.06-2.96). Overall disease recurrence rate was 14.1 %: 21.2 % in the anastomotic leakage group and 13.9% in the no leak group. There was a significant association between anastomotic leakage and local recurrence (hazard ratio = 4.63; 95% confidence interval, 1.60-10.6). In contrast, anastomotic leakage was not significantly associated with total distant recurrence. However, anastomotic leakage did show a tendency toward increasing peritoneal recurrence, although it did not reach statistical significance (hazard ratio = 2.59; 95 % confidence interval, 0.79-6.29).
    Conclusion. In our study population, anastomotic leakage was associated with reduced overall survival and with increased rate of local recurrence after curative resection for colon cancer.

    Background: Pneumonia is a major complication of influenza that contributes to mortality. Clinical characteristics and factors of influenza virus contributing to the severity and mortality of pneumonia have not been fully elucidated. Objective: The objective was to clarify clinical characteristics and factors contributing to the severity and mortality of influenza-associated pneumonia (flu-p†). Methods: We retrospectively analyzed patients with flu-p. Results: From December 1999 to March 2016, 210 patients with a median age of 69 (range, 17 to 92) years with flu-p based on positive rapid antigen tests, increased antibody titers of paired sera, or positive results of reverse transcription polymerase chain reaction were admitted to our institution. A multivariate analysis found that advanced age (≥ 65 years), pneumonia subtypes (unclassified), diabetes mellitus, and acute kidney injury complicated with flu-p were independent factors associated with disease severity, whereas pneumonia subtypes (mixed viral and bacterial pneumonia and unclassified), healthcare-associated pneumonia, acute kidney injury complicated with flu-p, and severity on admission (severe) were independent factors associated with non-survival. Conclusion: The clinical characteristics of flu-p are varied, and the contribution of several factors to the severity and mortality of flu-p suggest their importance in either preventing flu-p or managing flu-p after it develops.

    Adaptive designs in oncology clinical trials with interim analyses for population selection could be used in the development of targeted therapies if a predefined biomarker hypothesis exists. In this article, we consider an interim analysis using overall survival (OS), progression-free survival (PFS), and both OS and PFS, to determine whether the whole population or only the biomarker-positive population should continue into the subsequent stage of the trial, whereas the final decision is made based on OS data only. In order to increase the probability of selecting the most appropriate population at the interim analysis, we propose an interim decision-making strategy in adaptive designs with correlated endpoints considering the post-progression survival (PPS) magnitudes. In our approach, the interim decision is made on the basis of predictive power by incorporating information on OS as well as PFS to supplement the incomplete OS data. Simulation studies assuming a targeted therapy demonstrated that our interim decision-making procedure performs well in terms of selecting the proper population, especially under a scenario in which PPS affects the correlation between OS and PFS.

    INTRODUCTION: Impaired coordination between breathing and swallowing (breathing-swallowing discoordination) may be a significant risk factor for the exacerbation of chronic obstructive pulmonary disease (COPD). We examined breathing-swallowing discoordination in patients with COPD using a non-invasive and quantitative technique and determined its association with COPD exacerbation. METHODS: We recruited 65 stable outpatients with COPD who were enrolled in our prospective observational cohort study and did not manifest an apparent swallowing disorder. COPD exacerbation was monitored for 1 year before and 1 year after recruitment. Swallowing during inspiration (the I-SW pattern) and swallowing immediately followed by inspiration (the SW-I pattern) were identified. RESULTS: The mean frequency of the I-SW and/or SW-I patterns (I-SW/SW-I rate) was 21.5%±25.5%. During the 2-year observation period, 48 exacerbation incidents (25 patients) were identified. The I-SW/SW-I rate was significantly associated with the frequency of exacerbation. During the year following recruitment, patients with a higher I-SW/SW-I frequency using thicker test foods exhibited a significantly higher probability of future exacerbations (p=0.002, log-rank test). CONCLUSIONS: Breathing-swallowing discoordination is strongly associated with frequent exacerbations of COPD. Strategies that identify and improve breathing-swallowing coordination may be a new therapeutic treatment for patients with COPD.

    The aim of this study was to investigate the effect of the timing of valve surgery on the clinical outcomes of patients with active infective endocarditis (IE) accompanied by cerebral complications.
    We retrospectively analysed a cohort of 568 patients, comprising 118 with non-haemorrhagic cerebral infarction (CI), 54 with intracranial haemorrhage (ICH) and 396 without cerebral events (C; control), who underwent surgery for left-sided active IE in 15 Japanese institutes from 2000 to 2011. The mean age was 58.4 +/- 16.9 years in the CI group; 54.5 +/- 17.4 years in the ICH group and 56.9 +/- 16.0 years in the C group. Clinical outcomes were analysed according to the timing of surgery after the diagnosis of CI or ICH was made.
    In the CI group, there were 9 (7.6%) hospital deaths, 13 (11%) new cerebral events and 1 (0.8%) redo valve surgery. In the ICH group, there were 3 (5.6%) hospital deaths, 8 (14.8%) new cerebral events and 2 (3.7%) redo valve surgeries. In the C group, there were 36 (9.1%) hospital deaths, 23 (5.8%) new cerebral events and 9 (2.3%) redo valve surgeries. Risk factors for hospital death were prosthetic valve endocarditis (P = 0.045), high C-reactive protein (CRP; P &lt; 0.001) and the elderly (P &lt; 0.001) in the CI group. Delayed surgery (2 weeks after CI) seemed result in a higher incidence of hospital death in the CI group. Patients who had surgery between 15 and 28 days or after 29 days from the onset of CI had higher incidences of hospital death [odds ratio 5.90 (P = 0.107) and 4.92 (P = 0.137), respectively] compared with those who had surgery within 7 days. In the ICH group, risk factors for hospital death were high CRP (P = 0.002) and elderly (P &lt; 0.001). Contrary to CI patients, patients who had surgery between 8 and 21 days or after 22 days after the onset of ICH had lower incidences of hospital death [odds ratio 0.79 (P = 0.843) and 0.12 (P = 0.200), respectively] compared with those who had surgery within 7 days.
    Although statistically insignificant, early surgery in active IE patients with CI is safe, but very early surgery (within 7 days) should be avoided in patients with ICH.

    Background: Several diagnostic criteria have been proposed to differentiate allergic bronchopulmonary mycosis (ABPM) from asthma, but there have been no studies to establish diagnostic criteria to classify ABPM differently from other eosinophilic lung diseases. Methods: We retrospectively investigated both patients with ABPM (n=42) diagnosed by clinical (Rosenberg–Patterson criteria modified to apply to fungi other than Aspergillus spp., with consideration of computed tomography and bronchoscopy findings) or pathological criteria and those with other eosinophilic lung diseases (n=118) to establish elaborate diagnostic criteria for ABPM. Results: Etiologies of ABPM included fungi other than Aspergillus spp. or unidentified pathogens in 16 patients. Fourteen patients (33.3%) did not have asthma. When the diagnostic cutoff line was set to satisfy six or more primary plus secondary modified Rosenberg–Patterson criteria, ABPM could be diagnosed with good sensitivity, specificity, and positive/negative predictive values (97.6%, 98.3%, 95.3%, and 99.1%, respectively). When the diagnostic criteria were combined with pathological criteria, the values further improved to 100%, 98.3%, 95.5%, and 100%, respectively. Conclusions: Our results suggest that these novel criteria offer good sensitivity, specificity, and positive/negative predictive values for the diagnosis and classification of ABPM.

    Objective The long-term clinical course and prognosis of patients with chronic eosinophilic pneumonia (CEP) including factors predictive of the relapse of CEP have not been fully investigated. The aim of the present study was to investigate these issues.
    Methods We retrospectively investigated the rate of relapse and prognosis in 73 patients diagnosed as having CEP.
    Results Systemic corticosteroid therapy was administered at a prednisolone dose of 29.4 +/- 7.6 mg/day. During a median follow-up period of 1,939 days, 27 patients suffered from relapse of CEP. Two patients developed steroid-induced diabetes mellitus, and 1 patient developed pulmonary nontuberculous mycobacteriosis. Five patients died; however, none died of CEP. A history of smoking was the only independent negative risk factor for relapse of CEP [hazard ratio, 0.37 (0.14-0.98)].
    Conclusion Patients with CEP frequently relapse. During the follow-up, metabolic and infectious complications under prolonged corticosteroid therapy are problematic. A history of smoking was a negative factor for predicting the risk of CEP relapse.

    昨年度に検討した推進方策に基づき,本年度は,[1] 外部情報をベイズ流に事前情報として活用した統計解析手法の開発,[2] 比例ハザード性が成り立たない状況における生存時間解析手法と例数設計方法の開発,[3] 競合リスクを伴う生存時間解析の例数設計方法の開発を行った.
    [1] 昨年度は,外部情報をベイズ流に事前情報として活用した統計解析手法に関する文献調査を実施し,計算プログラムの作成を行った.本年度は,昨年度に得られた結果をもとに数値実験を実施し,国際学会および国内学会において研究成果の発表を行った.
    [2] 生存時間解析の常套手段として,群間のハザード比が時点に依らず一定である性質(比例ハザード性)のもとで統計解析が実施される.しかし,近年の医薬品開発では,比例ハザード性が成り立たない状況が増加している.本年度は,比例ハザード性が成り立たない状況における統計解析手法として,境界内平均生存時間に関して文献調査を実施し,提案法の開発,実行プログラムの作成,性能評価を行った.また,比例ハザード性が成り立たない状況下での例数設計方法についても開発した.
    [3] 例えば,ある疾患の再発を評価する場合を考えると,死亡が発生することによって,本来評価したい再発が評価できないことがある.このようなイベントは,イベント間でリスクが競合しているという意味で,競合リスクと呼ばれる.本年度は,競合リスクを考慮した生存時間解析の例数設計方法に関して文献調査を実施し,提案法の開発,実行プログラムの作成,性能評価を行った.
