Abstract
OBJECTIVE Long-term steroid use increases the risk of developing Pneumocystis pneumonia (PcP), but there are limited reports on the relation of long-term steroid and PcP mortality. METHODS Retrospective multicenter study to identify risk factors for PcP mortality, including average steroid dose before the first visit for PcP in non-human immunodeficiency virus (HIV)-PcP patients. We generated receiver operating characteristic (ROC) curves for 90-day all-cause mortality and the mean daily steroid dose per unit body weight in the preceding 10 to 90 days in 10-day increments. Patients were dichotomized by 90-day mortality and propensity score-based stabilized inverse probability of treatment weighting (IPTW) adjusted covariates of age, sex, and underlying disease. Multivariate analysis with logistic regression assessed whether long-term corticosteroid use affected outcome. RESULTS Of 133 patients with non-HIV-PcP, 37 died within 90 days of initial diagnosis. The area under the ROC curve for 1-40 days was highest, and the optimal cutoff point of median adjunctive corticosteroid dosage was 0.34 mg/kg/day. Past steroid dose, underlying interstitial lung disease and emphysema, lower serum albumin and lower lymphocyte count, higher lactate dehydrogenase, use of therapeutic pentamidine and therapeutic high-dose steroids were all significantly associated with mortality. Underlying autoimmune disease, past immunosuppressant use, and a longer time from onset to start of treatment, were associated lower mortality. Logistic regression analysis after adjusting for age, sex, and underlying disease with IPTW revealed that steroid dose 1-40 days before the first visit for PcP (per 0.1 mg/kg/day increment, odds ratio 1.36 [95% confidence interval = 1.16-1.66], P<0.001), low lymphocyte counts, and high lactate dehydrogenase revel were independent mortality risk factor, while respiratory failure, early steroid, and sulfamethoxazole/trimethoprim for PcP treatment did not. CONCLUSION A steroid dose before PcP onset was strongly associated with 90-day mortality in non-HIV-PcP patients, emphasizing the importance of appropriate prophylaxis especially in this population.

Abstract
OBJECTIVE We performed a retrospective study to evaluate the risk factors for acquiring Pneumocystis pneumonia (PCP) by pharmacologically immunosuppressed HIV-negative patients. METHODS Patients who received corticosteroids, immunosuppressive agents, anticancer agents, and radiotherapy with or without trimethoprim-sulfamethoxazole (TMP-SMX) at Himeji Medical Center between 2010 and 2021 were evaluated. Drugs and doses of the treatments for each patient were divided by month into person-month units. Each person-month datum includes information on the administered drug (or radiotherapy), average doses, and whether the patient had PCP during the corresponding month. ROC curves with person-month data were generated for each treatment, and AUCs >0.7 were identified as possessing positive classification utility. The risks for PCP according to gender, age (grouped by median) and each treatment were examined by univariate analysis, followed by multivariate analysis to identify independent factors. RESULTS Of a total of 17,733 patients (214,676 person-months), 32 developed PCP. The cut-off values by ROC analysis were 13.7 mg/day for corticosteroid (prednisolone equivalent), 0.92 mg/day (6.45 mg/week) for methotrexate (MTX), and 34.3 mg/day for TMP-SMX. The cut-off values for other treatments could not be estimated. The above three drugs and male sex were significant variables in univariate analysis and were all confirmed as independent factors by multivariate analysis. CONCLUSION The results suggest that a monthly average dose of ≥13.7 mg/day of prednisolone, ≥0.92 mg/day of MTX and male sex are significant independent risk factors for PCP, and that prophylaxis with ≥34.3 mg/day of TMP-SMX is to be recommended.

Abstract
The global phase III KEYNOTE-407 (NCT02775435) trial showed that pembrolizumab plus chemotherapy prolonged overall and progression-free survival (OS/PFS) versus placebo plus chemotherapy in patients with metastatic squamous non-small-cell lung cancer (NSCLC). We present outcomes of patients from Japan enrolled in KEYNOTE-407. Patients were randomized 1:1 to receive pembrolizumab 200 mg or placebo with paclitaxel 200 mg/m2 every 3 weeks (Q3W) or nab-paclitaxel 100 mg/m2 (weekly) plus carboplatin area under the concentration-time curve of 6 mg/mL/min Q3W for four cycles, followed by pembrolizumab or placebo Q3W for a total of 35 cycles. Primary end-points were OS and PFS per RECIST version 1.1 by blinded independent central review. Fifty patients were randomized at Japanese sites (pembrolizumab plus chemotherapy, n = 22; placebo plus chemotherapy, n = 28). Median follow-up time at data cut-off (May 9, 2019) was 15.1 (range, 0.5-24.0) months. Median OS (95% confidence interval [CI]) was 17.3 (12.5-not reached) versus 11.0 (8.6-19.5) months in the pembrolizumab plus chemotherapy versus placebo plus chemotherapy group (hazard ratio [HR] 0.56; 95% CI, 0.27-1.15). Median PFS (95% CI) was 8.3 (6.1-13.0) versus 7.2 (3.9-8.8) months (HR 0.65; 95% CI, 0.35-1.23). Grade 3-5 adverse events (AEs) occurred in 86% and 75% of patients, respectively. There were three fatal AEs, two of which were treatment-related (one from each treatment group, pneumonitis and pulmonary hemorrhage). Efficacy and safety outcomes were consistent with the global study and support the use of pembrolizumab plus chemotherapy in Japanese patients with metastatic squamous NSCLC.

Abstract
Recently, a certain volume of biopsy specimens has been required for genetic testing of tumors using endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). This study aimed to verify the superiority of our newly devised EBUS-TBNA biopsy technique, the "cross-fanning technique," which combines rotation and up-down maneuvers, by comparing its harvest volume with that of other maneuvers. Using a bronchoscope simulator, ultrasonic bronchoscope, and 21-gauge puncture needle, we compared the weight of silicone biopsy specimens obtained by the following 4 procedures: Conventional maneuver; Up-down maneuver; Rotation maneuver, and; Cross-fanning technique. Each procedure was repeated 24 times in total, rotating the sequences of the maneuvers, and the operator/assistant pair to align the conditions. The means ± standard deviations of the sample volumes for each puncture technique were as follows: 2.8 ± 1.2 mg; 3.1 ± 1.6 mg; 3.7 ± 1.2 mg, and; 3.9 ± 1.2 mg. There was a significant difference between the 4 groups (P = .024). The post hoc test showed a statistically significant difference between techniques A and D (P = .019). This study showed that the cross-fanning technique might contribute to the increased volume of tissue samples obtained by EBUS-TBNA biopsy.

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
The effectiveness of thoracoscopic biopsy as a diagnostic method for pleural diseases has been reported; however, obtaining a sufficient specimen size is sometimes difficult. Therefore, an ancillary technique, the precut technique using an injection needle, was devised to address this problem. This study aimed to evaluate the effectiveness and safety of the novel precut technique in patients with undiagnosed pleural effusion. This retrospective study included 22 patients who underwent pleural biopsy using the precut technique to examine exudative pleural effusion of unknown etiology. Thoracoscopy was performed under local anesthesia. The biopsy procedure was performed as follows: a needle was inserted into the pleura around the lesion using a semiflexible thoracoscope; the needle was positioned to make an incision in the pleura while injecting 1% lidocaine with epinephrine and lifting the pleura from the fascia; 2 or 3 precut incision lines were arranged in a triangle; and the specimen was obtained from the parietal pleura using forceps or a cryoprobe. Patient data including age, number of biopsies, biopsy specimen size, pathological and final diagnosis, and postoperative complications were examined. All patients were male with an average age of 74 years. Pleural effusion was found on the right and left sides in 16 and 6 patients, respectively. The average major axis of the biopsy specimens was 18 mm (range, 10-30 mm), which was sufficient to establish a pathological diagnosis. Only 1 patient experienced minor temporal bleeding as a complication. The precut technique enabled the procurement of specimens sufficient in size for pleural biopsy.

Abstract
Abstract
Study question
A prospective study to investigate the relationship between the composition of vaginal microbiota through next-generation sequencing and the efficacy of single frozen blastocyst transfer in the same cycle.
Summary answer
Dominant presence of lactobacillus and other lactate producing microbes in the upper vagina was highly correlated with implantation of transferred blastocyst in this pilot study.
What is known already
Next-generation sequencing of 16S rRNA detected microbes in the uterine cavity and recent studies indicated that dominant presence of Lactobacillus correlated highly with successful implantation of the transferred embryos. Aberrant vaginal microbiota has been known to cause poor obstetrical outcomes, however little is known for its effect on embryo implantation in assisted reproduction.
Study design, size, duration
A prospective study with 25 female subjects transferring a frozen blastocyst using autologous oocyte, over 14 months period in 2019-2020.
Participants/materials, setting, methods
25 female patients without tubal and uterine pathology and no history of multiple miscarriages and implantation failures were recruited with consent at a private ART clinic. Transdermal estrogen was used to prepare endometrium. Upper vaginal fluid was obtained in follicular phase of the the same cycle and analyzed through next-generation sequencing, but the result was reported after pregnancy confirmation. Single frozen blastocyst transfer and standard luteal phase support were performed. Institutional IRB approved the protocol.
Main results and the role of chance
The mean age was 36.2 y.o.(range 29-41 y.o.), and 14 gestational sacs (implantation rate 56%), and 3 miscarriage (21.4%) were observed. Next-generation sequencing for 16S rRNA revealed average 69.2% presence of Lactobacillus (0-100%) and average 78.0% (0.2-100%) lactate producing microbes (LPM: Lactobacillus, Bifidobacterium, Streptococcus, and Enterococcus) in the vaginal fluid. Using 90% as cut-off, implantation rates were 11/15 (73.3%) and 3/10 (30%) with Lactobacillus dominant and non-dominant, 12/16 (75%) and 2/9 (22.2%) with LPM dominant and non-dominant microbiota, respectively. The difference in each group were not statistically significant. The relative risks for pregnancy were 2.63 (95%CI 1.03-6.67, P=0.04) for Lactobacillus and 3.11 (95%CI 1.24-7.79, P=0.02) for LPM. As for ROC analysis for embryo implantation and dominant microbes, AUC and associated criterion were 0.62 and 90.7% (sensitivity 78.6%, specificity 72.7%) for Lactobacillus, 0.69 and 96.6% (sensitivity 85.7%, specificity 72.7%) for LPM, respectively. The difference of AUC was not significant (P=0.24).
Limitations, reasons for caution
Despite prospective nature of the study, small sample size limited the analytical power of the study. Aneuploidy screening was not performed to remove confounding factor.
Wider implications of the findings
Our pilot study revealed possible relationship between vaginal microbiota and embryo implantation. Dominance of Lactobacillus or other lactate producing microbes may be advantageous for successful ART. Sampling vaginal fluid for microbe analysis is less invasive than endometrial sampling and can obtain more abundant RNA with possible higher accuracy of analysis.

Abstract
Background In the phase 3 CASPIAN study (NCT03043872), first-line durvalumab plus etoposide and cisplatin or carboplatin (EP) significantly improved OS versus EP alone in patients with extensive-stage (ES)-SCLC (HR 0.73 [95% CI 0.59–0.91; p = 0.0047]). Here we report results for a preplanned subgroup analysis of patients recruited in Japan. Methods Treatment-naïve patients with ES-SCLC received either 4 cycles of durvalumab 1500 mg plus EP q3w followed by maintenance durvalumab 1500 mg q4w until disease progression or up to 6 cycles of EP q3w. The primary endpoint was OS. Secondary endpoints included progression-free survival (PFS), objective response rate (ORR), safety, and tolerability. Results In the Japan subgroup, 18 patients were randomized to durvalumab plus EP and 16 patients to EP. At the interim analysis with a median follow-up of 12.5 months in the subgroup, OS numerically favored durvalumab plus EP versus EP (HR 0.77 [95% CI 0.26‒2.26]; median not reached vs 15.2 months). PFS was similar for durvalumab plus EP versus EP (HR 0.90 [95% CI 0.43‒1.89]). Confirmed ORR was 89% with durvalumab plus EP versus 69% with EP. Adverse events (AEs) of CTCAE grade 3 or 4 were reported in 78% versus 94% of patients in the durvalumab plus EP versus EP arms. There were no AEs leading to treatment discontinuation or death in the Japan subgroup. Conclusion First-line durvalumab plus EP was effective and well tolerated in Japanese patients with ES-SCLC. Despite the small size of the Japan subgroup, results were generally consistent with the global study population.

Abstract
OBJECTIVE Sesamin is a major lignan constituent of sesame and possesses various health-promoting effects. Previous studies have demonstrated that sesamin extends the lifespan of Drosophila and Caenorhabditis elegans and corrects oxidative damage-related tissue dysfunction in mammals. To understand its anti-aging effects, we aimed to determine whether sesamin restores tissue function hampered by oxidative damage and suppresses several aging-related phenotypes using Drosophila senescence-accelerated models. MATERIALS AND METHODS We elucidated the anti-aging effects of sesamin on several aging-related phenotypes in the muscle, brain and midgut using the senescence-accelerated models (Sod1n1 mutant and Sod1-depleted flies) by immunostaining experiments. We determined the expression levels of several anti-oxidative and DNA repair genes using quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). We also identified the metabolite of sesamin in Drosophila by LC-MS/MS. RESULTS We confirmed that sesamin (0.35 and 2 mg/ml) extended the lifespan of the fly models. As observed in mammals, it can be absorbed and metabolized by Drosophila adults. The sesamin feeding suppressed the age-dependent impairment of locomotor activity and inhibited the accumulation of reactive oxygen species (ROS) in their bodies. Sesamin delayed the age-dependent accumulation of damaged proteins in the muscle, partially suppressed the loss of dopaminergic neurons in adult brains displaying ROS accumulation, and suppressed the accumulation of DNA damage and hyperproliferation of intestinal stem cells. Four antioxidative genes and two DNA repair genes were simultaneously upregulated in sesamin-fed adults. CONCLUSIONS: These observations represent the first direct evidence of the anti-aging effects of sesamin at the individual level. We propose that sesamin exerts anti-aging effects in the muscles, brain and midgut by inducing antioxidative and DNA repair genes, resulting in extended lifespan in flies.

Abstract
OBJECTIVES Afatinib is an effective treatment in patients who have epidermal growth factor receptor (EGFR) mutation-positive non-small-cell lung cancer (NSCLC), but its toxicities often require dose adjustment. Exploratory analyses of previous trials have suggested that reducing the dose of afatinib can decrease treatment-related adverse events without negatively affecting effectiveness. The aim of this study was to assess the efficacy and safety of low starting dose of afatinib with dose modification according to its toxicity in patients with EGFR mutation-positive NSCLC. MATERIALS AND METHODS This study was a multicenter, single-arm, open-label phase II trial. Treatment-naïve patients with advanced NSCLC positive for common EGFR mutations received afatinib starting in a dose of 20 mg/day. If tolerated, the dose was increased in 10-mg increments up to 50 mg/day. The primary endpoint was progression-free survival (PFS). RESULTS From February 2015 through March 2016, 46 patients were enrolled. The median age was 73 years (range, 43-86), and 35 patients (72%) were women.EGFR mutation subtypes included exon 19 deletion (54%) and Leu858Arg point mutation (46%). Most patients had a performance status of 0 or 1 (91%) and a histological diagnosis of adenocarcinoma (98%). As of the data cut-off date of June 2017, the median follow-up was 18.9 months. The median PFS was 15.2 months (95% CI: 13.2-not estimable). The 1-year overall survival rate was 95.6% (95% CI: 89.7%-100%). The objective response rate was 81.8% (95% CI, 81.3%-98.6%). Adverse events of grade 3 or higher occurred in 14 patients (30.4%) and included rash/acne in 4 patients (8.7%), paronychia in 4 patients (8.7%), diarrhea in 2 patients (4.3%). There was no treatment-related death. CONCLUSIONS Low starting dose of afatinib therapy showed promising clinical efficacy and good tolerability. Further investigations are warranted.

Abstract
Reflux following an esophagectomy with gastric conduit reconstruction in the posterior mediastinum is a clinically significant problem. In this study, we investigated the frequency and impact of reflux on the quality of life (QOL) among 158 patients who underwent an esophagectomy for esophageal cancer using an original questionnaire and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Version 3.0 (EORTC QLQ-C30). Reflux frequency was assessed using the original questionnaire. The number of patients who complained of reflux every day, two or three times a week, once a week, or less than once a week was 16 (10.1%), 21 (13.3%), 26 (16.5%), and 60 (38.0%), respectively. Out of 35 patients (22.2%) reported no reflux symptoms. Patients were divided into two groups: those with reflux ≥ once/week (63 patients) and those with low frequency of symptoms (95 patients). Time elapsed following surgery was the only factor to influence reflux frequency. Reflux frequency decreased within two years of surgery; however, the frequency plateaued after more than two years. QOL was assessed using the EORTC QLQ-C30. The ≥ once/week reflux group had a significantly lower global health status score than the low-frequency reflux group (59.6 ± 24.2 vs. 70.8 ± 20.7; P = 0.007). In addition, the ≥ once/week reflux group had a significantly lower social functioning score than the low-frequency reflux group (81.6 ± 24.1 vs. 88.4 ± 19.8; P = 0.035). Regarding symptoms, the ≥ once/week reflux group had significantly higher scores for fatigue, nausea, and vomiting, dyspnea and insomnia compared to the low-frequency reflux group (fatigue: 42.4 ± 21.9 vs. 28.9 ± 18.4, P < 0.001; nausea and vomiting: 17.3 ± 17.1 vs. 4.9 ± 10.6, P < 0. 001; dyspnea: 29.2 ± 26.0 vs. 21.7 ± 26.8, P = 0.043; insomnia: 22.2 ± 31.1 vs. 10.5 ± 21.7, P = 0.015). Thus, reflux after an esophagectomy was associated with a lower QOL.

Abstract
Neuronal and axonal responses to neurotrophic factors in the developing spinal cord have been relatively well characterized, but little is known about adult spinal responses to neurotrophic factors. We genetically modified primary rat fibroblasts to produce either nerve growth factor (NGF), brain-derived neurotrophic factor (BDNF), neurotrophin-3 (NT-3), or basic fibroblast growth factor (bFGF), then grafted these neurotrophic factor-secreting cells into the central gray matter of the spinal cord in adult rats. Spinal cord lesions were not made prior to grafting. From 2 wk to 6 mo later, sensory neurites of dorsal root origin extensively penetrated NGF-, NT-3-, and bFGF-producing grafts, whereas BDNF-secreting grafts elicited no growth responses. Putative noradrenergic neurites also penetrated NGF-secreting cell grafts. Local motor and corticospinal motor axons did not penetrate any of the neurotrophic factor-secreting grafts. These results indicate that unlesioned or minimally lesioned adult spinal cord sensory and putative noradrenergic populations retain significant neurotrophic factor responsiveness, whereas motor neurites are comparatively resistant even to those neurotrophic factors to which they exhibit survival dependence during development. Grafts of genetically modified cells can be a useful tool for characterizing neurotrophic factor responsiveness in the adult spinal cord and designing strategies to promote axonal regeneration after injury.

Abstract
BACKGROUND Organizing pneumonia (OP) is a histopathological response pattern to lung inflammation. It is clinically classified into cryptogenic OP and secondary OP, which is associated with various clinical conditions. Rapid resolution with corticosteroids and frequent relapses are common in OP. However, few studies have investigated the factors associated with OP relapse. METHODS The medical records of 75 patients with biopsy-proven OP, diagnosed between January 2010 and August 2015, who underwent corticosteroid therapy were retrospectively reviewed. Initially, the patients were all treated successfully; however, 31 patients experienced relapse thereafter (R group), whereas the others did not (NR group; 44 patients). The clinical, radiological, and pathological characteristics and administered corticosteroid doses were compared between the two groups. RESULTS The neutrophil percentage in the bronchoalveolar lavage (BAL) fluid and the level of fibrin deposition in lung biopsy specimens were higher in the R group than in the NR group (P=0.01 and P=0.002, respectively). The multivariate analysis demonstrated that both factors were statistically significant predictors of OP relapse. CONCLUSIONS A high neutrophil percentage in the BAL and the level of fibrin deposition in lung biopsy specimens are considered predictive factors of OP relapse during the tapering or after the cessation of steroid therapy. Patients without these findings may be treated with low-dose corticosteroids.

Abstract
A 67‐year‐old man with a history of asbestos exposure and rounded atelectasis complained of cough and swelling in the left submandibular region. Computed tomography showed an increase in size of the right lower lung lobe lesion, which was recognized as the pre‐existing rounded atelectasis, as well as swelling of the pancreas and submandibular glands. Biopsy from a submandibular gland and the pulmonary lesion led to a diagnosis of immunoglobulin G4‐related disease (IgG4‐RD). IgG4‐RD is a recently recognized disease that was first reported as an autoimmune disease; however, some reports have indicated another pathogenesis of an allergic nature that is characterized by type 2 helper T cell (Th2) inflammation. Additionally, it is recognized that long‐term exposure to asbestos can cause immune dysregulation. Here we present a case of IgG4‐RD associated with asbestos‐related pleural disease. Asbestos‐induced immune dysregulation may be one etiology of IgG4‐RD.

Abstract
The purpose of the present study was to use event-related potentials (ERP) to clarify the effect of magnetic stimulation on cognitive processing. A figure eight-shaped flat repetitive transcranial magnetic stimulation (rTMS) coil was used to stimulate either the region over the left or the right dorsolateral prefrontal cortex, which is considered to be the origin of the P300 component. Stimulus frequencies were 1.00, 0.75 and 0.50 Hz rTMS. The strength of the magnetic stimulation was set at 80% of the motor threshold for each participant. The auditory oddball task was used to elicit P300s before and shortly after rTMS, and comprised a sequence of sounds containing standard (1 kHz pure tone, 80% of trials) and deviant (2 kHz pure tone, 20% of trials) stimuli. We found that a 1.00 Hz rTMS pulse train over the left dorsolateral prefrontal cortex increased P300 latencies by 8.50 ms at Fz, 12.85 ms at Cz, and 11.25 ms at Pz. In contrast, neither 0.75 and 0.50 Hz rTMS pulse trains over the left dorsolateral prefrontal cortex nor 1.00, 0.75 and 0.50 Hz rTMS pulse trains over the right dorsolateral prefrontal cortex altered P300 latencies. These results indicate that rTMS frequency affects cognitive processing. Thus, we suggest that the effects of rTMS vary according to the activity of excitatory and inhibitory neurons in the cerebral cortex.

Abstract
Diffuse panbronchiolitis (DPB) is a chronic respiratory disease that mainly involves the respiratory bronchioles, and has historically been associated with a very poor prognosis. The development of long-term low dose macrolide therapy in the 1980s has dramatically improved the prognosis of DPB. Nevertheless, some cases are resistant to macrolide therapy, and ultimately develop severe respiratory failure and pulmonary hypertension; in such cases lung transplantation is a viable treatment option. Here we report the case of a 40-year-old patient with a 20-year history of DPB, who underwent bilateral lung transplantation due to severe respiratory failure with pulmonary hypertension.

Abstract
BACKGROUND Existing medical treatments have limitations in the management of very severe chronic obstructive pulmonary disease (COPD). METHODS We performed bronchoscopic lung volume reduction (BLVR) using transbronchial infusion of autologous blood and thrombin (BLVR with blood) in three patients with very severe COPD whose dyspnea could not be relieved by maximum medical management. Two patients underwent BLVR with blood in the left and right lungs at intervals of a half-year or a year, and one patient underwent this procedure in only the right lung. We assessed the changes in pulmonary function, exercise capacity and quality of life before and after BLVR with blood in a total of five procedures. RESULTS The subjects were 58- to 74-year-old males. Their forced expiratory volume in one second (FEV1) percent predicted ranged from 14.8% to 23.4%. BLVR with blood achieved significant improvements as follows (values before → after the procedure, mean ± standard deviation): FEV1 0.45r the L → 0.76r the L (P=0.004), inspiratory capacity 1.50cityo L → 2.05±.05c L (P=0.015), 3-minute walk test 46.8nuteo m → 89.6±34.5 m (P=0.004). Lung function peaked several months after BLVR with blood and returned to nearly the baseline level in 6 months, but exercise capacity was better than that at baseline for at least 12 months. St. George's Respiratory Questionnaire (SGRQ), measured in two patients before and 12 months after the procedure, showed remarkable improvements (-15.6 and -11.9 units). CONCLUSIONS BLVR with blood is an effective palliative treatment for very severe COPD.

Abstract
We herein report our experience with patients who had nontuberculous mycobacterial lung disease (NTM disease) accompanied by organizing pneumonia (OP). Out of 98 NTM disease patients who had undergone a biopsy or surgical resection, 11 patients had OP that was revealed histologically. After excluding six patients who had OP-related diseases (idiopathic interstitial pneumonia, rheumatoid arthritis, etc.), the remaining five patients were studied. Two of them (a 73-year-old man and a 66-year-old woman) showed common clinical feature: acute-onset symptoms of cough and fever, infiltrating shadows and dramatic improvement following treatment with a corticosteroid and anti-mycobacterial therapy. Our cases demonstrate that NTM disease is sometimes accompanied by OP histologically, and some such cases show common clinical features.

Abstract
BACKGROUND Rehabilitation for patients with Guillain-Barre Syndrome (GBS) is recommended as it improves the outcome of neurological deficits. Few studies focused on the effect of rehabilitation on mortality of the patients. AIM To investigate the effect of rehabilitation on hospital mortality of patients with GBS using the Japanese Diagnosis Procedure Combination (DPC) nationwide administrative claims database. DESIGN A retrospective observational cohort study. SETTING Hospitals adopting the Japanese DPC system. POPULATION Patients hospitalized with a diagnosis of GBS between July 2007 and October 2011. METHODS Data analyzed included sex, age, Barthel index at admission, use of ventilation, immune therapy, and rehabilitation during hospitalization, comorbidity, hospital volume, type of hospital, and in-hospital death. One-to-one propensity score-matching was used to compare hospital mortality rates within 30- and 90-days after admission in rehabilitation and non-rehabilitation groups. The adjusted odds ratios of rehabilitation to hospital mortality were also estimated. RESULTS A total of 3835 patients were identified and analyzed. Patients with advancing age, lower Barthel index at admission, comorbidities, ventilation, or immune therapy were more likely to receive rehabilitation during hospitalization. Propensity-matched analysis of 926 pairs showed that the rehabilitation group had lower hospital mortality rates within both 30- and 90-days than the non-rehabilitation group. The adjusted odds ratios of rehabilitation to hospital mortality within 30- and 90-days were 0.14 and 0.23, respectively. CONCLUSION After matching patients' background, rehabilitation was associated with lower hospital mortality of patients with GBS. CLINICAL REHABILITATION IMPACT Rehabilitation treatment is essential for patients with GBS to improve their survival.

Abstract
High-resolution CT showed areas of airspace consolidation with a twisted appearance of the airways, along with areas of peribronchial ground-glass attenuation and traction bronchiectasis, in five patients with interstitial pneumonia. These areas of airspace consolidation were termed "twisted consolidation" (TwC). The five patients included two patients receiving treatment for rheumatoid arthritis (RA), one patient with newly diagnosed RA, and one patient who subsequently showed RA. Three patients showed improvement after steroid administration. An association of TwC with RA is suspected, but further studies are necessary.

We herein describe a patient with IgG4-related lung disease (IgG4-RLD) who was radiologically and pathologically diagnosed with organizing pneumonia. He was successfully treated with a combination of prednisolone (PSL) and azathioprine (AZA), and his clinical course has been uneventful since tapering off PSL. This is a rare case of IgG4-RLD manifesting as organizing pneumonia, and, to our knowledge, this is also the first case showing the effectiveness of AZA in treating IgG4-RLD.

Abstract
Fibrodysplasia ossificans progressiva (FOP) is a rare, congenital disorder caused by heterozygous mutation of the bone morphogenetic protein type I receptor ACVR1. Various forms of atypical FOP have recently been identified, and a novel mutation, ACVR1 (587T>C), was reported in 2011. We report on the second patient worldwide with ACVR1 (587T>C) mutation. A 22-year-old Japanese male with no family history of heterotopic ossification did not show any malformation of the great toes and showed normal development from birth to the age of 17 years, when heterotopic ossification appeared in the lumbar area. The clinical symptoms were similar to those reported previously: the delayed onset with a slower and mild clinical course and little finger camptodactyly. Gene analysis revealed that the patient was heterozygous for ACVR1 (587T>C) mutation, the same one as reported in 2011, suggesting a correlation between the location of the mutation and the clinical symptoms. This second report of ACVR1 (587T>C) mutation worldwide is particularly meaningful in that it highlights the difference between clinical symptoms of the first reported patient with ACVR1 (587T>C) mutation and those of classic FOP.

Abstract
The effectiveness of degasification using a degassing membrane to improve chemical oxygen demand (COD) removal efficiency was investigated using a bench-scale upflow anaerobic sludge blanket (UASB) reactor. Vacuum degasification was able to transfer dissolved gas in the bulk liquid of the UASB reactor inside the membrane. Such a process might provide thermodynamically favorable conditions for the degradation of organic compounds. The COD-removal efficiency improved from 83% during normal operation to 90% during the degassing operation.

Abstract
OBJECTIVES Culture positivity of percutaneous aspiration material" is not included in the current bacteriological criteria for diagnosis of pulmonary nontuberculous mycobacterial (NTM) diseases, which were published by the Infectious Diseases Society of America (IDSA)/American Thoracic Society (ATS) in 2007 or those released by the Japanese Society for Tuberculosis in 2008. However, percutaneous aspiration is a reliable technique for the detection of causative microorganisms isolated from the focus of infection. We discuss the benefits of including positive culture of percutaneous aspiration material in the bacteriological diagnostic criteria of pulmonary NTM diseases. METHODS We reviewed the radiological images and clinical courses of pulmonary diseases in which NTM cultures were obtained from percutaneously aspirated materials at our hospital from 1991 to 2011. Aspiration was carried out under local anesthesia, usually with fluoroscopic guidance. After percutaneous insertion of a 22-gauge needle attached to a 20-mL syringe containing about 3 mL of saline, the lesion specimen was withdrawn together with the saline. After the needle was pulled out, the aspirated material and saline were transferred to test tubes for cytological and microbiological examinations. In patients with thin-walled cavitary lesions, saline was injected into the cavity and then aspirated. RESULTS Percutaneous aspiration was performed in 2,742 patients and NTM disease was detected in 51 patients. Of these 51 patients, 12 had solitary nodular lesions, and in many of these patients, no NTM bacilli could be detected in the sputa or bronchial washing specimens. Mycobacterium avium was identified in 10 of the 12 cases. Four of these 10 patients were followed up after their diagnosis without any treatment: 3 showed spontaneous reduction in lesion size, while 1 patient's condition remained unchanged. Four of the remaining 6 cases were treated with anti-NTM medications, and lesion size reduced in 2 cases, while no change or deterioration was seen in the other 2. Aspiration from solitary small cavitary lesions showed a relatively high number of NTM colonies. Pneumothorax was the only complication of the aspiration procedure. DISCUSSION If the diagnostic criteria for pulmonary NTM diseases include positive culture in percutaneous aspiration material, the diagnosis of solitary nodular NTM lesions would become easier; at present, these lesions are often diagnosed only upon surgical resection. Further, clinical studies on the possibility of spontaneous shrinkage of the solitary lesion and the value of its medical treatment would be promoted. Aspiration can easily differentiate NTM disease from pulmonary abscess or fungal infection in patients with a solitary lesion or small cavity.
