Here, we present a neonate case of pneumopericardium after cardiac surgery which was resolved after applying PPV. Case presentation A 28-day-old neonate with left recurrent nerve palsy after aortic reconstruction for interrupted aortic arch developed pericardial effusion. Pericardiocentesis was performed under general anesthesia, and a drainage tube was left in the pericardium. After extubation, stridor gradually exacerbated, following hemodynamic deterioration. A chest X-ray demonstrated pneumopericardium. Upper airway stenosis due to recurrent nerve palsy developed excessive negative pleural pressure, and air was drawn into pericardium via the insertion site of the drainage tube. After tracheal intubation and applying PPV, the pneumopericardium improved. Conclusion PPV does not always exacerbate pneumopericardium. In a patient with pericardial-atmosphere communication, increased inspiration effort can cause pneumopericardium, and PPV is a therapeutic option to alleviate the pneumopericardium. en-copyright= kn-copyright= en-aut-name=TaniMakiko en-aut-sei=Tani en-aut-mei=Makiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=KanazawaTomoyuki en-aut-sei=Kanazawa en-aut-mei=Tomoyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=ShiojiNaohiro en-aut-sei=Shioji en-aut-mei=Naohiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=ShimizuKazuyoshi en-aut-sei=Shimizu en-aut-mei=Kazuyoshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=IwasakiTatsuo en-aut-sei=Iwasaki en-aut-mei=Tatsuo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=MorimatsuHiroshi en-aut-sei=Morimatsu en-aut-mei=Hiroshi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= affil-num=1 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=2 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= affil-num=5 en-affil=Department of Anesthesiology and Resuscitology, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of Anesthesiology and Resuscitology, Graduate School of Medicine Dentistry and Pharmaceutical Sciences kn-affil= en-keyword=Pneumopericardium kn-keyword=Pneumopericardium en-keyword=Pericardiocentesis kn-keyword=Pericardiocentesis en-keyword=Recurrent nerve palsy kn-keyword=Recurrent nerve palsy en-keyword=Pleural pressure kn-keyword=Pleural pressure en-keyword=Positive pressure ventilation kn-keyword=Positive pressure ventilation END start-ver=1.4 cd-journal=joma no-vol=50 cd-vols= no-issue=8 article-no= start-page=863 end-page=871 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200121 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Pulmonary aspergillosis as a late complication after surgery for locally advanced non-small cell lung cancer treated with induction chemoradiotherapy en-subtitle= kn-subtitle= en-abstract= kn-abstract=Purpose
Some long-term survivors after surgery for locally advanced non-small cell lung cancer (NSCLC) treated with induction chemoradiotherapy (trimodality treatment) develop chronic pulmonary aspergillosis (CPA). The aim of our study was to assess the characteristics and outcomes of CPA that develops after trimodality treatment. Methods
We retrospectively reviewed the data of 187 NSCLC patients who underwent trimodality treatment between 1999 and 2018.
Results
Six male ever-smoker patients developed CPA. All 6 patients had undergone extended resection for NSCLC and had a history of either adjuvant chemotherapy (n?=?3) or radiation pneumonitis (n?=?4). Among the 4 patients with CPA localized in a single lung, 3 patients were treated surgically (completion pneumonectomy or cavernostomy) and 1 patient was treated with antifungal therapy alone. Both treatments led to the improved control of CPA. In contrast, patients with CPA in both lungs were not candidates for surgery, and died of CPA. The survival rates after trimodality treatment in the CPA group and the group without CPA were comparable (10-year survival rate, 50.0% vs. 57.6%, P?=?0.59).
Conclusion
The early diagnosis of CPA localized in a single lung after NSCLC surgery is critical to improving control and survival in patients with CPA. en-copyright= kn-copyright= en-aut-name=SugimotoSeiichiro en-aut-sei=Sugimoto en-aut-mei=Seiichiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=SohJunichi en-aut-sei=Soh en-aut-mei=Junichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=SuzawaKen en-aut-sei=Suzawa en-aut-mei=Ken kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MiyoshiKentaroh en-aut-sei=Miyoshi en-aut-mei=Kentaroh kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=OtaniShinji en-aut-sei=Otani en-aut-mei=Shinji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=YamamotoHiromasa en-aut-sei=Yamamoto en-aut-mei=Hiromasa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=OkazakiMikio en-aut-sei=Okazaki en-aut-mei=Mikio kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=YamaneMasaomi en-aut-sei=Yamane en-aut-mei=Masaomi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= en-aut-name=OtoTakahiro en-aut-sei=Oto en-aut-mei=Takahiro kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=9 ORCID= en-aut-name=KanazawaSusumu en-aut-sei=Kanazawa en-aut-mei=Susumu kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=10 ORCID= en-aut-name=KiuraKatsuyuki en-aut-sei=Kiura en-aut-mei=Katsuyuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=11 ORCID= en-aut-name=ToyookaShinichi en-aut-sei=Toyooka en-aut-mei=Shinichi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=12 ORCID= affil-num=1 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=2 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=3 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=4 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=5 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=6 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=7 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=8 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=9 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= affil-num=10 en-affil=Department of Radiology, Okayama University Hospital kn-affil= affil-num=11 en-affil=Department of Respiratory Medicine, Okayama University Hospital kn-affil= affil-num=12 en-affil=Department of General Thoracic Surgery, Okayama University Hospital kn-affil= en-keyword=Lung cancer kn-keyword=Lung cancer en-keyword=Aspergillosis kn-keyword=Aspergillosis en-keyword=Surgery kn-keyword=Surgery en-keyword=Radiation kn-keyword=Radiation en-keyword=Chemotherapy kn-keyword=Chemotherapy END start-ver=1.4 cd-journal=joma no-vol= cd-vols= no-issue= article-no= start-page= end-page= dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200603 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Comparative Gene Analysis Focused on Silica Cell Wall Formation: Identification of Diatom-Specific SET Domain Protein Methyltransferases en-subtitle= kn-subtitle= en-abstract= kn-abstract=Silica cell walls of diatoms have attracted attention as a source of nanostructured functional materials and have immense potential for a variety of applications. Previous studies of silica cell wall formation have identified numerous involved proteins, but most of these proteins are species-specific and are not conserved among diatoms. However, because the basic process of diatom cell wall formation is common to all diatom species, ubiquitous proteins and molecules will reveal the mechanisms of cell wall formation. In this study, we assembled de novo transcriptomes of three diatom species, Nitzschia palea, Achnanthes kuwaitensis, and Pseudoleyanella lunata, and compared protein-coding genes of five genome-sequenced diatom species. These analyses revealed a number of diatom-specific genes that encode putative endoplasmic reticulum-targeting proteins. Significant numbers of these proteins showed homology to silicanin-1, which is a conserved diatom protein that reportedly contributes to cell wall formation. These proteins also included a previously unrecognized SET domain protein methyltransferase family that may regulate functions of cell wall formation-related proteins and long-chain polyamines. Proteomic analysis of cell wall-associated proteins in N. palea identified a protein that is also encoded by one of the diatom-specific genes. Expression analysis showed that candidate genes were upregulated in response to silicon, suggesting that these genes play roles in silica cell wall formation. These candidate genes can facilitate further investigations of silica cell wall formation in diatoms. en-copyright= kn-copyright= en-aut-name=NemotoMichiko en-aut-sei=Nemoto en-aut-mei=Michiko kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=IwakiSayako en-aut-sei=Iwaki en-aut-mei=Sayako kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= en-aut-name=MoriyaHisao en-aut-sei=Moriya en-aut-mei=Hisao kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=3 ORCID= en-aut-name=MondenYuki en-aut-sei=Monden en-aut-mei=Yuki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=4 ORCID= en-aut-name=TamuraTakashi en-aut-sei=Tamura en-aut-mei=Takashi kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=5 ORCID= en-aut-name=InagakiKenji en-aut-sei=Inagaki en-aut-mei=Kenji kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=6 ORCID= en-aut-name=MayamaShigeki en-aut-sei=Mayama en-aut-mei=Shigeki kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=7 ORCID= en-aut-name=ObuseKiori en-aut-sei=Obuse en-aut-mei=Kiori kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=8 ORCID= affil-num=1 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=3 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=4 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=5 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=6 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=7 en-affil=Department of Biology, Tokyo Gakugei University kn-affil= affil-num=8 en-affil=Graduate School of Environmental and Life Science, Okayama University kn-affil= en-keyword=Biomineralization kn-keyword=Biomineralization en-keyword=Diatom kn-keyword=Diatom en-keyword=Silica kn-keyword=Silica en-keyword=Transcriptome kn-keyword=Transcriptome en-keyword=Proteome kn-keyword=Proteome END start-ver=1.4 cd-journal=joma no-vol=38 cd-vols= no-issue= article-no= start-page=233 end-page=239 dt-received= dt-revised= dt-accepted= dt-pub-year=2020 dt-pub=20200314 dt-online= en-article= kn-article= en-subject= kn-subject= en-title= kn-title=Relationships between mating tactics and male traits such as body size and fluctuating asymmetry in the Japanese scorpionfly en-subtitle= kn-subtitle= en-abstract= kn-abstract=Fluctuating asymmetry (FA) is defined as small, random deviations from perfect bilateral symmetry in a morphological trait. It has sometimes been used as an indicator of male quality because it affects male mating success. In the Japanese scorpionfly, Panorpa japonica, males are known to use two mating tactics, donation of nuptial gifts and forced mating. In P. japonica, low FA males are more likely to win a competition with another male, and females prefer low FA male sex pheromones. However, no studies have been conducted on the effect of FA on the mating tactics adopted by males. In the present study, we first observed the mating behaviors of P. japonica and classified these into three patterns: (1) nuptial gifting, (2) forced mating, and (3) feeding mating. Second, we investigated the relationships between mating tactics and male traits, including body size, FA, and weapon size. The results showed a positive correlation between absolute FA and mating duration only in the case of feeding mating. We discuss the reasons why this significant correlation was found in P. japonica. en-copyright= kn-copyright= en-aut-name=IshiharaRyo en-aut-sei=Ishihara en-aut-mei=Ryo kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=1 ORCID= en-aut-name=MiyatakeTakahisa en-aut-sei=Miyatake en-aut-mei=Takahisa kn-aut-name= kn-aut-sei= kn-aut-mei= aut-affil-num=2 ORCID= affil-num=1 en-affil=raduate School of Environmental and Life Science, Okayama University kn-affil= affil-num=2 en-affil=Graduate School of Environmental and life Science, Okayama University kn-affil= en-keyword=Copulation kn-keyword=Copulation en-keyword=Courtship kn-keyword=Courtship en-keyword=Mating duration kn-keyword=Mating duration en-keyword=Panorpa japonica kn-keyword=Panorpa japonica END
