| 1 | Post-polypectomy bleeding and thromboembolism risks associated with warfarin vs direct oral anticoagulants显示文摘AIM To verify the validity of the endoscopy guidelines for patients taking warfarin or direct oral anticoagulants(DOAC).METHODS We collected data from 218 patients receiving oral anticoagulants(73 DOAC users, 145 warfarin users) and 218 patients not receiving any antithrombotics(age-and sexmatched controls) who underwent polypectomy.(1) We evaluated post-polypectomy bleeding(PPB) risk in patients receiving warfarin or DOAC compared with controls;(2) we assessed the risks of PPB and thromboembolism between three AC management methods: Discontinuing AC with heparin bridge(HPB)(endoscopy guideline recommendation), continuing AC, and discontinuing AC without HPB.RESULTS PPB rate was significantly higher in warfarin users and DOAC users compared with controls(13.7% and 13.7% vs 0.9%, P < 0.001), but was not significantly different between rivaroxaban(13.2%), dabigatran(11.1%), and apixaban(13.3%) users. Two thromboembolic events occurred in warfarin users, but none in DOAC users. Compared with the continuing anticoagulant group, the discontinuing anticoagulant with HPB group(guideline recommendation) had a higher PPB rate(10.8% vs 19.6%, P = 0.087). These findings were significantly evident in warfarin but not DOAC users. One thrombotic event occurred in the discontinuing anticoagulant with HPB group and the discontinuing anticoagulant without HPB group; none occurred in the continuing anticoagulant group.CONCLUSION PPB risk was similar between patients taking warfarin and DOAC. Thromboembolism was observed in warfarin users only. The guideline recommendations for HPB should be re-considered. | Naohiro Yanagisawa Naoyoshi Nagata Kazuhiro Watanabe Tatsuhiro Iida Mariko Hamada Sakurako Kobayashi Takuro Shimbo Junichi Akiyama Naomi Uemura | 2018 | World Journal of Gastroenterology2018，24，14： | 6 |
| 2 | Hemorrhagic shock due to submucosal esophageal hematoma along with mallory-weiss syndrome:A case report显示文摘BACKGROUND Esophageal submucosal hematoma is a rare condition.Although the exact etiology remains uncertain,vessel fragility with external factors is believed to have led to submucosal bleeding and hematoma formation;the vessel was ruptured by a sudden increase in pressure due to nausea,and the hematoma was enlarged by antiplatelet or anticoagulant therapy.Serious conditions are rare,with a better prognosis.We present the first known case of submucosal esophageal hematoma-subsequent hemorrhagic shock due to Mallory-Weiss syndrome.CASE SUMMARY A 73-year-old female underwent endovascular treatment for an unruptured cerebral aneurysm.The patient received aspirin and clopidogrel before surgery and heparin during surgery,and was well during the surgery.Several hours after returning to the ICU,she complained of chest discomfort,vomited 500 m L of fresh blood,and entered hemorrhagic shock.Esophageal submucosal hematoma with Mallory-Weiss syndrome was diagnosed through an endoscopic examination and computed tomography.In addition to a massive fluid and erythrocyte transfusion,we performed a temporary compression for hemostasis with a Sengstaken-Blakemore(S-B)tube.Afterwards,she became hemodynamically stable.On postoperative day 1,we performed an upper gastrointestinal endoscopy and confirmed no expansion of the hematoma nor any recurring bleeding;therefore,we removed the S-B tube and clipped the gastric mucosal laceration at the esophagogastric junction.We started oral intake on postoperative day 10.The patient made steady progress,and was discharged on postoperative day 33.CONCLUSION We present the first known case of submucosal esophageal hematoma subsequent hemorrhagic shock due to Mallory-Weiss syndrome. | Jiro Oba Daisuke Usuda Shiho Tsuge Riki Sakurai Kenji Kawai Shun Matsubara Risa Tanaka Makoto Suzuki Hayabusa Takano Shintaro Shimozawa Yuta Hotchi Kenki Usami Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Tomohisa Nomura Manabu Sugita | 2022 | World Journal of Clinical Cases2022，10，27： | 3 |
| 3 | Angiotensin receptor blocker neprilysin inhibitors显示文摘Heart failure(HF)is a clinical syndrome that results from a structural or functional cardiac disorder that reduces the ability of the ventricle of the heart to fill with,or eject,blood.It is a multifaceted clinical condition that affects up to 2%of the population in the developed world,and is linked to significant morbidity and mortality;it is therefore considered a major concern for public health.Regarding the mechanism of HF,three neurohumoral factors-the reninangiotensin-aldosterone system,the sympathetic nervous system,and natriuretic peptides—are related to the pathology of chronic HF(CHF),and the targets of treatment.Angiotensin receptor blocker and neprilysin inhibitor(angiotensinreceptor neprilysin inhibitor),namely sacubitril/valsartan(SAC/VAL),has been introduced as a treatment for CHF.SAC/VAL is an efficacious,safe,and costeffective therapy that improves quality of life and longevity in patients with HF with reduced ejection fraction(HFrEF),and reduces hospital admissions.An inhospital initiation strategy offers a potential new avenue to improve the clinical uptake of SAC/VAL.In the last five years,SAC/VAL has been established as a cornerstone component of comprehensive disease-modifying medical therapy in the management of chronic HFrEF.On the other hand,further work,with carefully designed and controlled preclinical studies,is necessary for understanding the molecular mechanisms,effects,and confirmation of issues such as long-term safety in both human and animal models. | Daisuke Usuda Toshihiro Higashikawa Yuta Hotchi Kenki Usami Shintaro Shimozawa Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Toshihiko Yoshizawa Suguru Asako Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2021 | World Journal of Cardiology2021，13，8： | 2 |

| 5 | Effects of liraglutide on metabolic syndrome in WBN/Kob diabetic fatty rats supplemented with a high-fat diet显示文摘Background:Liraglutide,a GLP-1 receptor agonist,has recently been used to treat metabolic syndrome(MS)because of its anti-diabetic and anti-obesity effects.We have previously shown that Wistar Bonn Kobori diabetic and fatty(WBN/Kob-Leprfa,WBKDF)rats fed a high-fat diet(HFD)developed MS including marked obesity,hyperglycemia,and dyslipidemia.To obtain further information on WBKDF-HFD rats as a severe MS model,we performed a pharmacological investigation into the anti-MS effects of liraglutide in this model.Methods:Seven-week-old male WBKDF-HFD rats were allocated to three groups(n=8 in each group):a vehicle group,a low-dose liraglutide group,and a high-dose liraglutide group.They received subcutaneous injections of either saline or liraglutide at doses of 75 or 300μg/kg body weight once daily for 4 weeks.Results:Results showed that liraglutide treatment reduced body weight gain and food intake in a dose-dependent manner.The marked hyperglycemia and the glucose tolerance were also significantly ameliorated in the liraglutide-treated groups.Moreover,liraglutide also reduced the plasma triglyceride concentration and liver fat accumulation.Conclusions:The present study demonstrated that liraglutide could significantly alleviate MS in WBKDF-HFD rats,and the reaction to liraglutide is similar to human patients with MS.WBKDF-HFD rats are therefore considered to be a useful model for research on severe human MS. | Noriyuki Kaji Yoshiichi Takagi Satomi Matsuda Anna Takahashi Sakurako Fujio Fumitoshi Asai | 2020 | Animal Models and Experimental Medicine2020，3，1： | 1 |

| 14 | Amebic liver abscess by Entamoeba histolytica显示文摘Amebic liver abscesses(ALAs)are the most commonly encountered extraintestinal manifestation of human invasive amebiasis,which results from Entamoeba histolytica(E.histolytica)spreading extraintestinally.Amebiasis can be complicated by liver abscess in 9%of cases,and ALAs led to almost 50000 fatalities worldwide in 2010.Although there have been fewer and fewer cases in the past several years,ALAs remain an important public health problem in endemic areas.E.histolytica causes both amebic colitis and liver abscess by breaching the host’s innate defenses and invading the intestinal mucosa.Trophozoites often enter the circulatory system,where they are filtered in the liver and produce abscesses,and develop into severe invasive diseases such as ALAs.The clinical presentation can appear to be colitis,including upper-right abdominal pain accompanied by a fever in ALA cases.Proper diagnosis requires nonspecific liver imaging as well as detecting anti-E.histolytica antibodies;however,these antibodies cannot be used to distinguish between a previous infection and an acute infection.Therefore,diagnostics primarily aim to use PCR or enzyme-linked immunosorbent assay to detect E.histolytica.ALAs can be treated medically,and percutaneous catheter drainage is only necessary in approximately 15%of cases.The indicated treatment is to administer an amebicidal drug(such as tinidazole or metronidazole)and paromomycin or other luminal cysticidal agent for clinical disease.Prognosis is good with almost universal recovery.Establishing which diagnostic methods are most efficacious will necessitate further analysis of similar clinical cases. | Daisuke Usuda Shiho Tsuge Riki Sakurai Kenji Kawai Shun Matsubara Risa Tanaka Makoto Suzuki Hayabusa Takano Shintaro Shimozawa Yuta Hotchi Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2022 | World Journal of Clinical Cases2022，10，36： | 0 |
| 15 | High doses of dextromethorphan induced shock and convulsions in a 19-year-old female:A case report显示文摘BACKGROUND Dextromethorphan is a prevalent antitussive agent that can be easily obtained as an over-the-counter medication.There has been a growing number of reported cases of toxicity in recent years.Generally,there are numerous instances of mild symptoms,with only a limited number of reports of severe cases necessitating intensive care.We presented the case of a female who ingested 111 tablets of dextromethorphan,leading to shock and convulsions and requiring intensive care that ultimately saved her life.CASE SUMMARY A 19-year-old female was admitted to our hospital via ambulance,having overdosed on 111 tablets of dextromethorphan(15 mg)obtained through an online importer in a suicide attempt.The patient had a history of drug abuse and multiple self-inflicted injuries.At the time of admission,she exhibited symptoms of shock and altered consciousness.However,upon arrival at the hospital,the patient experienced recurrent generalized clonic convulsions and status epilepticus,necessitating tracheal intubation.The convulsions were determined to have been caused by decreased cerebral perfusion pressure secondary to shock,and noradrenaline was administered as a vasopressor.Gastric lavage and activated charcoal were also administered after intubation.Through systemic management in the intensive care unit,the patient’s condition stabilized,and the need for vasopressors ceased.The patient regained consciousness and was extubated.The patient was subsequently transferred to a psychiatric facility,as suicidal ideation persisted.CONCLUSION We report the first case of shock caused by an overdose of dextromethorphan. | Shintaro Shimozawa Daisuke Usuda Toru Sasaki Shiho Tsuge Riki Sakurai Kenji Kawai Shun Matsubara Risa Tanaka Makoto Suzuki Yuta Hotchi Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Suguru Asako Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2023 | World Journal of Clinical Cases2023，11，16： | 0 |
| 16 | Penile and scrotal strangulation by stainless steel rings in an human immunodeficiency virus positive man: A case report显示文摘BACKGROUND Penoscrotal constriction devices are either used as autoerotic stimuli or to increase sexual pleasure or performance by maintaining an erection for a longer period,and a variety of metallic and non-metallic objects are used.On the other hand,penile strangulation is a rare urologic emergency that requires prompt evaluation and intervention to prevent long-term complications.The goal of treating penile incarceration is to remove the foreign object as soon as possible.On the other hand,removal can be very challenging,and often requires resourcefulness and a multidisciplinary approach.CASE SUMMARY A 47-year-old man who has sex with men was transferred to our hospital for persistent phallodynia and scrotal pain,accompanying swelling due to strangulation by stainless steel rings.His medical history included acquired immunodeficiency syndrome.One day prior,he had put three stainless steel rings on his penis and scrotum before sexual intercourse.After sexual intercourse,he was unable to remove them,due to swelling of his penis and scrotum.The swelling persisted,and he felt pain in the affected area the next day,then he was transferred to our hospital by ambulance.The emergency department found that his penis and scrotum were markedly engorged and swollen.We established a diagnosis of penile and scrotal strangulation by stainless steel rings.We unsuccessfully attempted to cut the rings using a cutter,then requested a rescue team via emergency medical service.They cut through each ring in two places,using an electric-powered angle grinder,and successfully removed all of the pieces.Finally,he was discharged and went home.CONCLUSION We report the first case of penile and scrotal strangulation by stainless steel rings in an human immunodeficiency virus positive person. | Daisuke Usuda Nobuyoshi Kaminishi Masashi Kato Yuto Sugawara Runa Shimizu Tomotari Inami Shiho Tsuge Riki Sakurai Kenji Kawai Shun Matsubara Risa Tanaka Makoto Suzuki Shintaro Shimozawa Yuta Hotchi Ippei Osugi Risa Katou Sakurako Ito Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2023 | World Journal of Clinical Cases2023，11，24： | 0 |
| 17 | Secondary pulmonary infection by Fusarium solani and Aspergillus niger during systemic steroid treatment for COVID-19:A case report显示文摘BACKGROUND Coronavirus disease 2019(COVID-19)-associated invasive pulmonary aspergillosis presents a diagnostic challenge due to its non-specific clinical/imaging features,as well as the fact that the proposed clinically diagnostic algorithms do not necessarily apply to COVID-19 patients.In addition,Fusarium spp.is a rare cause of opportunistic life-threatening fungal infections.Disseminated Fusarium infection in an immunocompromised host is intractable,with a high likelihood of resulting mortality.To our knowledge,this is the first case of secondary pulmonary infection by Fusarium solani(F.solani)and Aspergillus niger(A.niger)during systemic steroid treatment for COVID-19.CASE SUMMARY A 62-year-old male was transported to our hospital by ambulance with a complaint of fever and dyspnea.We established a diagnosis of pneumococcal pneumonia,complicated with COVID-19 and septic shock,together with acute renal failure.He was admitted to the intensive care unit,to be treated with piperacillin/tazobactam,vancomycin,and 6.6 mg per day of dexamethasone sodium phosphate,along with noradrenaline as a vasopressor,ventilator management,and continuous hemodiafiltration.His condition improved,and we finished the vasopressor on the fifth hospital day.We administered dexamethasone for ten days,and finished the course of treatment.On the eleventh day,patient respiratory deterioration was observed,and a computed tomography scan showed an exacerbation of bilateral ground-glass-opacity-like consolidation,together with newly appeared cavitary lesions in the lung.we changed antibiotics to meropenem plus vancomycin.In addition,a fungal infection was considered as a possibility based on microscopic findings of sputum,and we began coadministration of voriconazole.However,the pneumonia worsened,and the patient died on the seventeenth day of illness.Later,F.solani and A.niger were identified from sputum collected on the twelfth day.It was believed that he developed a cell-mediated immune deficiency during COVID-19 treatment,which led to the complication of pneumonia caused by the above-mentioned fungi,contributing to his death.CONCLUSION Because early initiation of intense antifungal therapy offers the best chance for survival in pulmonary fusariosis,computed tomography scans and appropriate microbiologic investigations should be obtained for severely immunocompromised patients. | Daisuke Usuda Masashi Kato Yuto Sugawara Runa Shimizu Tomotari Inami Shiho Tsuge Riki Sakurai Kenji Kawai Shun Matsubara Risa Tanaka Makoto Suzuki Shintaro Shimozawa Yuta Hotchi Ippei Osugi Risa Katou Sakurako Ito Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2023 | World Journal of Clinical Cases2023，11，26： | 0 |
| 18 | The assembly of the Milky Way and its satellite galaxies显示文摘In recent years it has become clear that the Milky Way is an important testing ground for theories of galaxy formation. Much of this growth has been driven by large surveys, both photometric and spectroscopic, which are producing vast and rich catalogs of data. Through the analysis of these data sets we can gain new and detailed insights into the physical processes which shaped the Milky Way's evolution. This review will discuss a number of these developments, first focusing on the disk of the Milky Way, and then looking at its satellite population. The importance of surveys has not gone unnoticed by the Chinese astronomy community and in the final section we discuss a number of Chinese projects that are set to play a key role in the development of this field. | Martin C.

| 19 | Exophiala dermatitidis显示文摘Exophiala is a genus comprising several species of opportunistic black yeasts,which belongs to Ascomycotina.It is a rare cause of fungal infections.However,infections are often chronic and recalcitrant,and while the number of cases is steadily increasing in both immunocompromised and immunocompetent people,detailed knowledge remains scarce regarding infection mechanisms,virulence factors,specific predisposing factors,risk factors,and host response.The most common manifestations of Exophiala infection are skin infections,and the most frequent type of deep infection is pulmonary infection due to inhalation.The invasive disease ranges from cutaneous or subcutaneous infection to systemic dissemination to internal organs.The final identification of the causative organism should be achieved through a combination of several methods,including the newly introduced diagnostic analysis,matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry,together with sequencing of the ribosomal ribonucleic acid internal transcribed spacer region of the fungi,and histological and culture findings.Regarding treatment,because anti-infective agents and natural compounds exhibited poor antibiofilm activity,few treatments have ultimately been found to be effective for specific antifungal therapy,so the optimal antifungal therapy and duration of therapy for these infections remain unknown.Therefore,most forms of disease caused by Exophiala dermatitidis require aggressive combination therapies:Both surgical intervention and aggressive antifungal therapy with novel compounds and azoles are necessary for effective treatment. | Daisuke Usuda Toshihiro Higashikawa Yuta Hotchi Kenki Usami Shintaro Shimozawa Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Toshihiko Yoshizawa Suguru Asako Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita | 2021 | World Journal of Clinical Cases2021，9，27： | 0 |
| 20 | Diffuse large B cell lymphoma originating from the maxillary sinus with skin metastases:A case report and review of literature显示文摘BACKGROUND Diffuse large B-cell lymphoma(DLBCL)is the most common type of malignant lymphoma(ML),accounting for 30%-40%of cases of non-Hodgkin’s lymphoma(NHL)in adults.Primary paranasal sinus lymphoma is a rare presentation of extranodal NHL that accounts for only 0.17%of all lymphomas.ML from the maxillary sinus(MS)is a particularly rare presentation,and is thus often difficult to diagnose.We have reported the first known case of DLBCL originating from the MS with rapidly occurrent multiple skin metastasis.CASE SUMMARY An 81-year-old Japanese man visited our hospital due to continuous pain for 12 d in the left maxillary nerve area.His medical history included splenectomy due to a traffic injury,an old right cerebral infarction from when he was 74-years-old,hypertension,and type 2 diabetes mellitus.A plain head computed tomography(CT)scan revealed a 3 cm×3.1 cm×3 cm sized left MS.On day 25,left diplopia and ptosis occurred,and a follow-up CT on day 31 revealed the growth of the left MS mass.Based on an MS biopsy on day 50,we established a definitive diagnosis of DLBCL,non-germinal center B-cell-like originating from the left MS.The patient was admitted on day 62 due to rapid deterioration of his condition,and a plain CT scan revealed the further growth of the left MS mass,as well as multiple systemic metastasis,including of the skin.A skin biopsy on day 70 was found to be the same as that of the left MS mass.We notified the patient and his family of the disease,and they opted for palliative care,considering on his condition and age.The patient died on day 80.CONCLUSION This case suggests the need for careful,detailed examination,and for careful follow-up,when encountering patients presenting with a mass. | Daisuke Usuda Toshihide Izumida Nao Terada Ryusho Sangen Toshihiro Higashikawa Sayumi Sekiguchi Risa Tanaka Makoto Suzuki Yuta Hotchi Shintaro Shimozawa Shungo Tokunaga Ippei Osugi Risa Katou Sakurako Ito Suguru Asako Yoshie Takagi Kentaro Mishima Akihiko Kondo Keiko Mizuno Hiroki Takami Takayuki Komatsu Jiro Oba Tomohisa Nomura Manabu Sugita Yuji Kasamaki | 2021 | World Journal of Clinical Cases2021，9，23： | 0 |
