Abstract
We report a pediatric case developing hypoglycemic encephalopathy during the acute phase of coxsackievirus (CV)-A4 infection. A part of the sequence of the virus detected from our patient was completely identical to that in other CV-A4 strain reported as a recombinant strain with lethal CV-A2, suggesting that the properties of CV-A4 might be associated with the severe hypoglycemic encephalopathy.

Identifying the population susceptible to rubella in Japan, 2020: Fine-scale risk mapping. J Infect Public Health 2024; 17:947-955. [PMID: 38608455 DOI: 10.1016/j.jiph.2024.03.029] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/26/2023] [Revised: 03/13/2024] [Accepted: 03/27/2024] [Indexed: 04/14/2024] Open
Abstract
BACKGROUND Rubella remains a public health challenge in Japan, impeding the attainment of herd immunity. Despite vaccination efforts since 1976, persistent outbreaks reveal a susceptibility gap in male adults born before 1995. Seroepidemiological surveys are pivotal in evaluating population immunity and identifying at-risk groups. METHODS This study aims to pinpoint high-risk areas for potential rubella outbreaks in Japan by merging seroepidemiological data from 2020 with population census information. Various data sources, including spatial demographic data, reported rubella and congenital rubella syndrome (CRS) cases, and traveler lodging statistics, were employed. Geospatial information for Japan's 230,300 small geographic areas was analyzed, and HI (hemagglutination inhibition) titers were examined by age and sex. Seroconversion was defined as an HI titer ≥ 1:32 or 1:16, indicating protective immunity. Geospatial maps illustrated the distribution of susceptible individuals per square kilometer, emphasizing high-risk urban areas like Tokyo and Osaka. Demographic shifts in the working-age population were assessed. RESULTS Susceptible individuals cluster in densely populated urban centers, persisting despite demographic changes. The study highlights areas at risk of increased susceptibility, particularly with an HI titer cut-off of 1:16. Foreign travelers pose potential rubella importation risks as travel volume to Japan rises. To prevent epidemics and congenital rubella syndrome burden, achieving and sustaining herd immunity in high-risk areas is crucial. CONCLUSIONS This study offers a comprehensive assessment of vulnerability in densely populated Japanese regions. Integrating population statistics with seroepidemiological data enhances our understanding of population immunity, guiding resource allocation for supplementary vaccination planning. To avert rubella epidemics, high-risk locations must bolster indirect protection through herd immunity, ultimately preventing congenital rubella syndrome.

Efficacy of laparoscopic surgery for loop colostomy: a propensity-score-matched analysis. Tech Coloproctol 2023; 27:1319-1326. [PMID: 37725263 DOI: 10.1007/s10151-023-02856-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Accepted: 08/09/2023] [Indexed: 09/21/2023]
Abstract
PURPOSE Colostomy is a common procedure for fecal diversion, but the optimal colostomy approach is unclear in terms of surgical outcomes and stoma-related complications. The purpose of this study was to examine the efficacy and feasibility of laparoscopic loop colostomy. METHODS This retrospective cohort study included patients who underwent loop colostomy at Shizuoka Cancer Center in Japan between April 2010 and March 2022. Patients were divided into two groups based on surgical approach: the laparoscopic (LAP) and open (OPEN) groups. Surgical outcomes and the incidences of stoma-related complications such as stomal prolapse (SP), parastomal hernia (PSH), and skin disorders (SD) were compared with and without propensity score matching. RESULTS Of the 388 eligible patients, 180 (46%) were in the LAP group and 208 (54%) were in the OPEN group. The male-to-female ratio was 5.5:4.5 in the Lap group and was 5.3:4.7 in the OPEN group, respectively. The median age was 68 years (range, 31-88 years) in the LAP group and 65 years (range, 23-93 years) in the OPEN group, respectively. The LAP group, compared with the OPEN group, had a shorter operative time and lower incidences of surgical site infection (3.9% versus 16.3%, respectively; p < 0.01) and SD (11.7% versus 24.5%, respectively; p < 0.01). There was no significant difference between the LAP and OPEN groups in the incidence of SP (17.3% versus 17.3%, respectively) or PSH (8.9% versus 6.7%, respectively). After propensity score matching, the incidences of surgical site infection and SD were significantly lower in the LAP group than in the OPEN group, while there were no significant differences in the operative time or the incidences of SP and PSH. CONCLUSION Our results suggest that laparoscopic surgery could be beneficial and feasible in loop colostomy.

Abstract
PURPOSE/OBJECTIVE(S) Myeloproliferative neoplasms including primary and secondary myelofibrosis (MF) are a rare spectrum of chronic myeloproliferative disorders in which nearly 90% of patients experience splenomegaly. Importantly, splenic radiotherapy (SRT) may be used in combination with allogeneic stem cell transplant (alloSCT) to improve symptoms related to splenomegaly, though there currently is no consensus SRT dose/fractionation protocol reported in the literature for use in combination with alloSCT. We sought to report our institutional experience utilizing low dose SRT prior to alloSCT in the post-Jakafi era. MATERIALS/METHODS We performed a retrospective review of all patients diagnosed with MF at our institution from 2017-2022 who received reduced intensity alloHCT. Patients who underwent total lymphoid or body irradiation were excluded. Descriptive demographic and clinical characteristics of patients were summarized by means, medians, standard deviations, ranges and proportions as appropriate. RESULTS We identified 39 patients with MF who underwent reduced intensity conditioning (RIC) consisting of fludarabine/melphalan in preparation for alloHCT (median age 64.5, 12/16 males, median follow up 21 months). 16 patients with Jakafi-resistant splenomegaly completed low dose SRT prior to transplant (median spleen size: 24.5cm) with a median dose of 5Gy delivered in 5 fractions. 3D conformal therapy was used for all patients. All patients completed the planned total radiation course without treatment break or dose limiting acute toxicity. Thrombocytopenia was the most reported toxicity (CTCAE v5.0; 2 patients experienced grade 1, 1 patient experienced grade 2). No patients experienced grade 3 or higher acute cytopenias nor required transfusion during radiotherapy. All patients successfully received alloHCT a median of 7 days (range: 2-11) after the completion of SRT with a 94% (15/16) engraftment rate. Median neutrophil recovery (ANC > 500 × 3 days) time was 18 days (range: 13-31); median length of hospital stay was 23 days (range: 20-129). Overall survival was 75% in the SRT cohort (12/16, 2 with persistent disease, 2 due to other causes). Symptom burden data was available for 14/16 patients; 79% (11/14) of patients reported improvement in symptoms associated with splenomegaly or reduction in splenic size on physical examination. CONCLUSION In the largest reported experience of a low dose SRT only cohort to date, we observe low dose SRT is feasible, safe in combination with alloHCT with high engraftment rates, and may reduce symptoms related to splenomegaly thereby improving patient quality of life without compromising transplant related outcomes. A prospective study validating this protocol is currently underway.

Abstract
A nationwide survey of SARS-CoV-2 antinucleocapsid seroprevalence among blood donors in Japan revealed that, as of November 2022, infection-induced seroprevalence of the population was 28.6% (95% CI 27.6%-29.6%). Seroprevalence studies might complement routine surveillance and ongoing monitoring efforts to provide a more complete real-time picture of COVID-19 burden.

Abstract
Earlier, we demonstrated the co-circulation of genetically distinct non-rodent-borne hantaviruses, including Boginia virus (BOGV) in the Eurasian water shrew (Neomys fodiens), Seewis virus (SWSV) in the Eurasian common shrew (Sorex araneus) and Nova virus (NVAV) in the European mole (Talpa europaea), in central Poland. To further investigate the phylogeny of hantaviruses harbored by soricid and talpid reservoir hosts, we analyzed RNAlater®-preserved lung tissues from 320 shrews and 26 moles, both captured during 1990-2017 across Poland, and 10 European moles from Ukraine for hantavirus RNA through RT-PCR and DNA sequencing. SWSV and Altai virus (ALTV) were detected in Sorex araneus and Sorex minutus in Boginia and the Białowieża Forest, respectively, and NVAV was detected in Talpa europaea in Huta Dłutowska, Poland, and in Lviv, Ukraine. Phylogenetic analyses using maximum-likelihood and Bayesian methods showed geography-specific lineages of SWSV in Poland and elsewhere in Eurasia and of NVAV in Poland and Ukraine. The ATLV strain in Sorex minutus from the Białowieża Forest on the Polish-Belarusian border was distantly related to the ATLV strain previously reported in Sorex minutus from Chmiel in southeastern Poland. Overall, the gene phylogenies found support long-standing host-specific adaptation.

Abstract
As coronavirus disease 2019 (COVID-19) outbreaks in healthcare facilities are a serious public health concern, we performed a case-control study to investigate the risk of COVID-19 infection in healthcare workers. We collected data on participants' sociodemographic characteristics, contact behaviors, installation status of personal protective equipment, and polymerase chain reaction testing results. We also collected whole blood and assessed seropositivity using the electrochemiluminescence immunoassay and microneutralization assay. In total, 161 (8.5%) of 1,899 participants were seropositive between August 3 and November 13, 2020. Physical contact (adjusted odds ratio 2.4, 95% confidence interval 1.1-5.6) and aerosol-generating procedures (1.9, 1.1-3.2) were associated with seropositivity. Using goggles (0.2, 0.1-0.5) and N95 masks (0.3, 0.1-0.8) had a preventive effect. Seroprevalence was higher in the outbreak ward (18.6%) than in the COVID-19 dedicated ward (1.4%). Results showed certain specific risk behaviors of COVID-19; proper infection prevention practices reduced these risks.

Abstract
Background Based on routine surveillance data, Japan has been affected much less by COVID-19 compared with other countries. To validate this, we aimed to estimate SARS-CoV-2 seroprevalence and examine sociodemographic factors associated with cumulative infection in Japan. Methods A population-based serial cross-sectional seroepidemiological investigation was conducted in five prefectures in December 2021 (pre-Omicron) and February-March 2022 (Omicron [BA.1/BA.2]-peak). Anti-nucleocapsid and anti-spike antibodies were measured to detect infection-induced and vaccine/infection-induced antibodies, respectively. Logistic regression was used to identify associations between various factors and past infection. Results Among 16 296 participants (median age: 53 [43-64] years), overall prevalence of infection-induced antibodies was 2.2% (95% CI: 1.9-2.5%) in December 2021 and 3.5% (95% CI: 3.1-3.9%) in February-March 2022. Factors associated with past infection included those residing in urban prefectures (Tokyo: aOR 3.37 [95% CI: 2.31-4.91], Osaka: aOR 3.23 [95% CI: 2.17-4.80]), older age groups (60s: aOR 0.47 [95% CI 0.29-0.74], 70s: aOR 0.41 [95% CI 0.24-0.70]), being vaccinated (twice: aOR 0.41 [95% CI: 0.28-0.61], three times: aOR 0.21 [95% CI: 0.12-0.36]), individuals engaged in occupations such as long-term care workers (aOR: 3.13 [95% CI: 1.47-6.66]), childcare workers (aOR: 3.63 [95% CI: 1.60-8.24]), food service workers (aOR: 3.09 [95% CI: 1.50-6.35]), and history of household contact (aOR: 26.4 [95% CI: 20.0-34.8]) or non-household contact (aOR: 5.21 [95% CI:3.80-7.14]) in February-March 2022. Almost all vaccinated individuals (15 670/15 681) acquired binding antibodies with higher titers among booster dose recipients. Conclusions Before Omicron, the cumulative burden was >10 times lower in Japan (2.2%) compared with the US (33%), the UK (25%), or global estimates (45%), but most developed antibodies owing to vaccination.

Abstract
In Japan, large-scale mumps epidemics recur every 4-6 years because of low vaccination coverage. This study aimed to describe the seroprevalence of mumps in the Japanese population and identify the age groups most affected. The prevalence of anti-mumps antibodies was evaluated based on 1000 serum samples obtained from the Japanese National Serum Reference Bank. These samples consisted of 50 sera for each of 10 different age groups, collected during 2007-2008 (pre-epidemic period) and 2012-2013 (post-epidemic period). Seropositivity was lowest in the 6-11 months subgroup (3% and 0% in pre- and post-epidemic periods, respectively) and highest in the 10-14 years group (66% and 72% in pre- and post-epidemic periods, respectively). A comparison of anti-mumps antibody prevalence throughout the two periods considered revealed a large rise in seropositivity among the 2004-2008 birth cohort, using that of the 1-4 years group as representative in the pre-epidemic period (from 22% in pre- to 58% in post-epidemic periods; p = 0.0002). These results indicate that most people likely gain antibodies to the mumps virus during their childhood, especially during the first epidemic that they experience after their second year of life. Therefore, children should be vaccinated against mumps soon after their first birthday for effective prevention.

Abstract
INTRODUCTION The coronavirus disease 2019 (COVID-19), including the Omicron variant, is less severe in children than in adults. To date, there has been no detailed description of COVID-19-associated severe encephalopathy due to the Omicron variant during the neonatal and early infantile periods. CASE PRESENTATION During the outbreak of the Omicron variant, a 29-day-old male presented with a pale and ill appearance. The patient was intubated for mechanical ventilation owing to recurrent apnea, which subsequently turned out to be a breath-holding that may have been caused by seizure. In addition, nonconvulsive status epilepticus was observed. Total duration of repetitive seizure activities was approximately 30 min per hour when seizures were most severe. Brain magnetic resonance imaging (MRI) on day 14 revealed extensive hyperintensity in the T2 sequence, hypointensity in the fluid-attenuated inversion recovery (FLAIR) sequence in the deep and subcortical white matter, and diffusion restriction in the corpus callosum. The Omicron BA.1 variant of the severe acute respiratory syndrome coronavirus 2 was detected in his respiratory sample. Follow-up MRI on day 45 revealed multiple cystic cavitations. CONCLUSION Although COVID-19 is not severe in most children, life-threatening conditions such as COVID-19-associated severe encephalopathy can occur during the neonatal and early infantile periods.

Abstract
Coronavirus disease 2019 (COVID-19) vaccine administration started in February 2021 in Japan. As of December 2021, approximately 75% of the population aged ≥12 years had received two doses of vaccine. We conducted a study to investigate vasovagal reactions (VVR) after COVID-19 vaccination using data on adverse events following immunization. The crude reporting rate of VVR (cases/1,000,000 doses) after vaccination was 9.6 in all age groups combined, and was more frequent in the younger age groups: 28.6 and 37.2 in individuals aged 10–19 years and 20–29 years, respectively. In individuals aged 10–29 years, the rate was similar in males and females (33.0 and 34.2, respectively, p = 0.53); but was higher after dose 1 than after dose 2 (57.4 and 8.8, respectively, p < 0.001). Based on these results, caution needs to be exercised when vaccinating adolescents and young adults, especially with dose 1 of COVID-19 vaccines.

OP0090 PRECLINICAL STUDIES OF A NOVEL CATHEPSIN C INHIBITOR IN MPO-ANCA-ASSOCIATED VASCULITIS MODEL. Ann Rheum Dis 2022.

Abstract
BackgroundMPO-ANCA-associated vasculitis (MPO-AAV) is a systemic small vessel vasculitis with the production of MPO-ANCA in the serum. This disease develops necrotizing and crescent glomerulonephritis (NCGN) and peritubular capillaritis-mediated interstitial damages in the kidneys, and pulmonary hemorrhage due to capillaritis in the lungs. Recent studies have revealed that neutrophil extracellular traps (NETs) induced by MPO-ANCA are critically involved in its pathogenesis,1 and neutrophil elastase (NE) plays an essential role in the formation of NETs.2 Cathepsin C (CatC) functions as a key enzyme in the activation process of several neutrophil serine proteases (NSPs) such as NE, proteinase 3 and cathepthin G by converting the inactive forms of the NSPs to the active forms by digesting dipeptides at the N-terminus of the enzymes.3ObjectivesAlthough glucocorticoids and immunosuppressive drugs used as the standard of cares can lead remission in MPO-AAV patients, there are remaining unmet medical needs such as severe side effects, resistance to the treatment and relapse. Therefore, development of new therapeutic strategies is awaited. The aim of this study is to demonstrate the efficacy of MOD06051, a novel CatC inhibitor, against MPO-AAV, using an MPO-AAV rat model established previously.4MethodsIn vitro studies: Cathpsins and NE inhibitory activity was measured using recombinant enzymes and fluorescent substrates. Cellular NE activity in the granulocytes differentiated from the primary human bone marrow-derived hematopietic stem cells under the presence or absence of MOD06051 was determined using fluorescent substrates.In vivo studies: 4-week-old Wistar Kyoto (WKY) rats were immunized with human MPO according to Little’s protocol.4 The rats were divided into three groups (n=8 in each group), and vehicle (0.5% methylcellulose) or MOD06051 (0.3 or 3 mg/kg bid) was orally administered every day for 42 days. All rats were euthanized at the end of the study for serological and histological evaluations.ResultsIn vitro studies: MOD06051 inhibited the enzymatic activity of human recombinant CatC with an IC50 value of 1.5 nM, and no other cathepsins nor NE inhibition was observed at 10 μM. The NE activity in primary human granulocytes was suppressed by MOD06051 with an IC50 value of 18 nM.In vivo studies: MPO-ANCA was induced in all groups at the same level. The percentage of affected glomeruli including those with NCGN, NET-forming neutrophils in the peripheral blood and glomeruli, and glomerular neutrophil counts were significantly suppressed by MOD06051 treatment in a dose-dependent manner. Furthermore, hematuria score, urinary NGAL (Neutrophil Gelatinase-Associated Lipocalin), tubular erythrocyte cast counts, and pulmonary hemorrhage foci were significantly decreased in the 3 mg/kg of MOD06051 treated group with the similar trends in 0.3 mg/kg group.ConclusionMOD06051 showed sepcific inhibition of CatC activity. This compound suppressed the serine proteases activation in primary human neutrophils and NET formation in the MPO-AAV model rats, resulting in amelioration of MPO-ANCA-induced tissue destruction, including NCGN and tubular interstitial damages in the kidneys, and disorder of alveolar septal capillaries in the lungs. MOD06051 appears to be a promising agent for treatment of MPO-AAV patients.References[1]Nakazawa D, et al. Nat Rev Rheumatol 15: 91-101, 2019.[2]Papayannopoulos V, et al.

[PMID: 35223726 PMCID: PMC8873109 DOI: 10.3389/fpubh.2022.775486] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Accepted: 01/18/2022] [Indexed: 11/13/2022] Open
Abstract
Two-sided messages that include two perspectives (i.e., risks and benefits) are more effective than one-sided messages that convey only one perspective (usually only the benefits). Refutational two-sided messages are effective for communicating risks regarding vaccines. To examine the effectiveness of refutational two-sided messages in risk communication regarding novel vaccines against emerging infectious diseases, we conducted the randomized controlled study based on a 3 × 3 × 2 mixed design (Intervention 1: vaccines against subcutaneous influenza, “novel severe infectious disease,” or intranasal influenza; intervention 2: one-sided, non-refutational two-sided, or refutational two-sided messages; two questionnaires) using a Japanese online panel. Participants completed questionnaires before and after receiving an attack message (negative information). We evaluated the impact of attack messages on the willingness to be vaccinated, and the anticipated regret of inaction (ARI). Among 1,184 participants, there was a significant difference in the willingness to be vaccinated among the message groups (p < 0.01). After receiving the attack message, willingness to be vaccinated decreased in the one-sided message group and increased in the non-refutational two-sided and refutational two-sided message groups. Additionally, ARI in the refutational two-sided message groups was significantly higher than in the one-sided groups (p = 0.03). In conclusion, two-sided messages are more effective than one-sided messages in terms of willingness to be vaccinated. Furthermore, the high ARI in the refutational two-sided message group indicated that refutational two-sided messages were more effective than one-sided messages for communicating the risks of vaccines, especially those against emerging infectious diseases.

Abstract
This is the English version of guidelines for the management of asteatosis 2021 in Japan. Asteatosis is a synonym of xerosis found in a wide range of diseases that induce dry skin through impaired functions of either water retention of the stratum corneum or skin covering with acid mantle. Patients with asteatosis may be accompanied by pruritus. Moisturizers are the first-line treatment for asteatosis and their adequate use must be recommended. The main purpose of the present guidelines is to define skin symptoms requiring treatment with moisturizers for medical use in patients with asteatosis. If the deterioration of marked scaling or scratch marks is predicted, therapeutic intervention with moisturizers for medical use should be considered even in the absence of pruritus. Regarding six important points requiring decision-making in clinical practice (clinical questions), we evaluated the balance between the benefits and harm of medical interventions in reference to previous reports of clinical research, and presented the recommendation grades and evidence levels to optimize the patient outcome by medical interventions.

Clinical practice guidance for childhood-onset systemic lupus erythematosus-secondary publication. Mod Rheumatol 2021; 32:239-247.

Abstract
Childhood-onset systemic lupus erythematosus (cSLE) has been recognised as a more acute and severe autoimmune disease than adult-onset SLE. With the development of medications for the disease and supportive therapy, the mortality rate associated with cSLE has drastically improved; the 10-year survival rate among patients with cSLE between 1995 and 2006 in Japan was 98.3%. However, the 10-year survival rate without any permanent functional impairment remained low at 66.1%. Therefore, the current treatment goal for cSLE is to ensure that they can perform normal daily activities throughout their lives by preventing the occurrence and/or progression of organ damage. For this purpose, appropriate treatments and evaluations are required according to the severity and risk of organ damage; however, there are no established guidelines for cSLE. Therefore, the Pediatric Rheumatology Association of Japan and the Pediatric Rheumatology Subcommittee in the Japan College of Rheumatology developed a comprehensive guidance for clinical practice based on cSLE-related data collected from Japanese national surveys and relevant articles from both domestic and international sources. However, due to the lack of indications for defined and objective evidence quality levels, this guidance should be used on the basis of the judgement of the attending physicians for individual patients.

Abstract
Hantaviruses are harbored by multiple small mammal species in Asia, Europe, Africa, and the Americas. To ascertain the geographic distribution and virus-host relationships of rodent-borne hantaviruses in Japan, Vietnam, Myanmar, and Madagascar, RNAlater™-preserved lung tissues of 981 rodents representing 40 species, collected in 2011-2017, were analyzed for hantavirus RNA by RT-PCR. Our data showed Hantaan orthohantavirus Da Bie Shan strain in the Chinese white-bellied rat (Niviventer confucianus) in Vietnam, Thailand; orthohantavirus Anjo strain in the black rat (Rattus rattus) in Madagascar; and Puumala orthohantavirus Hokkaido strain in the grey-sided vole (Myodes rufocanus) in Japan. The Hokkaido strain of Puumala virus was also detected in the large Japanese field mouse (Apodemus speciosus) and small Japanese field mouse (Apodemus argenteus), with evidence of host-switching as determined by co-phylogeny mapping.

Geographic Distribution and Phylogeny of Soricine Shrew-Borne Seewis Virus and Altai Virus in Russia. Viruses 2021; 13:1286.

Abstract
The discovery of genetically distinct hantaviruses (family Hantaviridae) in multiple species of shrews, moles and bats has revealed a complex evolutionary history involving cross-species transmission. Seewis virus (SWSV) is widely distributed throughout the geographic ranges of its soricid hosts, including the Eurasian common shrew (Sorex araneus), tundra shrew (Sorex tundrensis) and Siberian large-toothed shrew (Sorex daphaenodon), suggesting host sharing. In addition, genetic variants of SWSV, previously named Artybash virus (ARTV) and Amga virus, have been detected in the Laxmann's shrew (Sorex caecutiens). Here, we describe the geographic distribution and phylogeny of SWSV and Altai virus (ALTV) in Asian Russia. The complete genomic sequence analysis showed that ALTV, also harbored by the Eurasian common shrew, is a new hantavirus species, distantly related to SWSV. Moreover, Lena River virus (LENV) appears to be a distinct hantavirus species, harbored by Laxmann's shrews and flat-skulled shrews (Sorex roboratus) in Eastern Siberia and far-eastern Russia. Another ALTV-related virus, which is more closely related to Camp Ripley virus from the United States, has been identified in the Eurasian least shrew (Sorex minutissimus) from far-eastern Russia. Two highly divergent viruses, ALTV and SWSV co-circulate among common shrews in Western Siberia, while LENV and the ARTV variant of SWSV co-circulate among Laxmann's shrews in Eastern Siberia and far-eastern Russia. ALTV and ALTV-related viruses appear to belong to the Mobatvirus genus, while SWSV is a member of the Orthohantavirus genus. These findings suggest that ALTV and ALTV-related hantaviruses might have emerged from ancient cross-species transmission with subsequent diversification within Sorex shrews in Eurasia.

Abstract
A 4-year-old male neutered English bulldog presented for heart murmur evaluation. Echocardiography identified severe pulmonic stenosis (an echocardiography-derived transpulmonary pressure gradient of 100 mmHg), and computed tomography confirmed the presence of an anomalous coronary artery with a prepulmonic course of the left coronary artery arising from the right coronary ostium. Before artificial pulmonic valve implantation, a coronary compression test was performed. A simultaneous aortic root angiogram and pulmonic balloon valvuloplasty revealed complete occlusion of the circumflex branch. Artificial valve implantation was aborted with concern for fatal coronary compression after implantation. Coronary compression testing is a critical component of the evaluation before catheter-based implantation of conduits across the pulmonic valve.

Abstract
Mass gatherings are events characterized by “the concentration of people at a specific location for a specific purpose over a set period of time that have the potential to strain the planning and response resources of the host country or community.” Previous reports showed that, as a result of the concentration of people in the limited area, injury and illness occurred due to several factors. The response plan should aim to provide timely medical care to the patients and to reduce the burden on emergency hospitals, and to maintain a daily emergency medical services system for residents of the local area. Although a mass gathering event will place a significant burden on the local health‐care system, it can provide the opportunity for long‐term benefits of public health‐care and improvement of daily medical service systems after the end of the event. The next Olympic and Paralympic Games will be held in Tokyo, during which mass gatherings will occur on a daily basis in the context of the coronavirus disease (COVID‐19) epidemic. The Academic Consortium on Emergency Medical Services and Disaster Medical Response Plan during the Tokyo Olympic and Paralympic Games in 2020 (AC2020) was launched 2016, consisting of 28 academic societies in Japan, it has released statements based on assessments of medical risk and publishing guidelines and manuals on its website. This paper outlines the issues and countermeasures for emergency and disaster medical care related to the holding of this big event, focusing on the activities of the academic consortium.

Abstract
The infectivity of shrew-borne hantaviruses to humans is still unclear because of the lack of a serodiagnosis method for these viruses. In this study, we prepared recombinant nucleocapsid (rN) proteins of Seewis orthohantavirus, Altai orthohantavirus (ALTV), Thottapalayam thottimvirus (TPMV), and Asama orthohantavirus. Using monospecific rabbit sera, no antigenic cross-reactivity was observed. In a serosurvey of 104 samples from renal patients and 271 samples from heathy controls from Sri Lanka, one patient serum and two healthy control sera reacted with rN proteins of ALTV and TPMV, respectively. The novel assays should be applied to investigate potential infectivity of shrew-borne hantaviruses to humans.

Reassortment Between Divergent Strains of Camp Ripley Virus ( Hantaviridae) in the Northern Short-Tailed Shrew ( Blarina brevicauda). Front Cell Infect Microbiol 2020; 10:460.

Abstract
Genomic reassortment of segmented RNA virus strains is an important evolutionary mechanism that can generate novel viruses with profound effects on human and animal health, such as the H1N1 influenza pandemic in 2009 arising from reassortment of two swine influenza viruses. Reassortment is not restricted to influenza virus and has been shown to occur in members of the order Bunyavirales. The majority of reassortment events occurs between closely related lineages purportedly due to molecular constraints during viral packaging. In the original report of Camp Ripley virus (RPLV), a newfound hantavirus in the northern short-tailed shrew (Blarina brevicauda), phylogenetic incongruence between different genomic segments suggested reassortment. We have expanded sampling to include RPLV sequences amplified from archival tissues of 36 northern short-tailed shrews collected in 12 states (Arkansas, Iowa, Kansas, Maryland, Massachusetts, Michigan, Minnesota, New Hampshire, Ohio, Pennsylvania, Virginia, Wisconsin), and one southern short-tailed shrew (Blarina carolinensis) from Florida, within the United States. Using Bayesian phylogenetic analysis and Graph-incompatibility-based Reassortment Finder, we identified multiple instances of reassortment that spanned the Hantaviridae phylogenetic tree, including three highly divergent, co-circulating lineages of the M segment that have reassorted with a conserved L segment in multiple populations of B. brevicauda. In addition to identifying the first known mobatvirus-like M-segment sequences from a soricid host and only the second from a eulipotyphlan mammal, our results suggest that reassortment may be common between divergent virus strains and provide strong justification for expanded spatial, temporal, and taxonomic analyses of segmented viruses.

Abstract
Murid and cricetid rodents were previously believed to be the principal reservoir hosts of hantaviruses. Recently, however, multiple newfound hantaviruses have been discovered in shrews, moles, and bats, suggesting a complex evolutionary history. Little is known about the genetic diversity and geographic distribution of the prototype shrew-borne hantavirus, Thottapalayam thottimvirus (TPMV), carried by the Asian house shrew (Suncus murinus), which is widespread in Asia, Africa, and the Middle East. Comparison of TPMV genomic sequences from two Asian house shrews captured in Myanmar and Pakistan with TPMV strains in GenBank revealed that the Myanmar TPMV strain (H2763) was closely related to the prototype TPMV strain (VRC66412) from India. In the L-segment tree, on the other hand, the Pakistan TPMV strain (PK3629) appeared to be the most divergent, followed by TPMV strains from Nepal, then the Indian-Myanmar strains, and finally TPMV strains from China. The Myanmar strain of TPMV showed sequence similarity of 79.3-96.1% at the nucleotide level, but the deduced amino acid sequences showed a high degree of conservation of more than 94% with TPMV strains from Nepal, India, Pakistan, and China. Cophylogenetic analysis of host cytochrome b and TPMV strains suggested that the Pakistan TPMV strain was mismatched. Phylogenetic trees, based on host cytochrome b and cytochrome c oxidase subunit I genes of mitochondrial DNA, and on host recombination activating gene 1 of nuclear DNA, suggested that the Asian house shrew and Asian highland shrew (Suncus montanus) comprised a species complex. Overall, the geographic-specific clustering of TPMV strains in Asian countries suggested local host-specific adaptation. Additional in-depth studies are warranted to ascertain if TPMV originated in Asian house shrews on the Indian subcontinent.

Abstract
This case–control study investigated immune thrombocytopenic purpura (ITP) risk following live, inactivated, and simultaneous vaccination, with a focus on infants aged < 2 years. We matched case patients with ITP to one or two control patients with other diseases by institution, hospital visit timing, sex, and age. We calculated McNemar’s pairwise odds ratios (ORs [95% confidence interval]) with 114 case–control pairs. The case group had 27 (44%) males and 22 (35%) infants, and the control group included 49 (43%) males and 42 (37%) infants. For all age groups, the McNemar’s OR for ITP occurrence was 1.80 (0.54–6.84, p = 0.64) for all vaccines. Among infants, these were 1.50 (0.17–18.0, p = 0.50) for all vaccines, 2.00 (0.29–22.1, p = 0.67) for live vaccines, and 1.00 (0.01–78.5, p = 0.50) for inactivated vaccines. Sex-adjusted common ORs for simultaneous vaccination were 1.52 (0.45–5.21, p = 0.71) for all vaccines, 1.83 (0.44–7.59, p = 0.40) for inactivated vaccines only, and 1.36 (0.29–6.30, p = 0.69) for mixed live and inactivated vaccines. In infants, these were 1.95 (0.44–8.72, p = 0.38), 1.41 (0.29–6.94, p = 0.67) and 2.85 (0.43–18.9, p = 0.28), respectively. These limited data suggest no significant ITP risk following vaccinations or simultaneous vaccination in any age group, including infants.

Abstract
BACKGROUND Angioleiomyomas typically present as small, painful, soft-tissue tumors less than 2 cm in diameter. The features of angioleiomyomas on magnetic resonance (MR) imaging are not well understood, and the association of MR findings with histologic subtype is unclear. In the present study, the MR features of angioleiomyomas of average size were compared in relation to histologic subtype. METHODS This retrospective review of medical records analyzed MR imaging data and histologic specimens from 18 consecutive patients with angioleiomyomas that were resected at our hospital during the period from January 2006 through December 2013. RESULTS On T1-weighted images, lesions exhibited homogeneous areas that were isointense with skeletal muscle. However, T2-weighted images of solid and venous angioleiomyomas showed heterogeneous areas that were isointense or slightly hyperintense, while cavernous angioleiomyomas exhibited hyperintensity. Most lesions had a hypointense rim, and two thirds had adjacent vessels. CONCLUSIONS Our results suggest that MR findings for angioleiomyoma vary in relation to histologic subtype. T2-weighted images of solid and venous angioleiomyomas yielded specific MR findings that allowed for differentiation from other soft-tissue tumors, such as soft-tissue sarcomas. Most of these tumors exhibited isointense to slightly hyperintense regions, as compared with skeletal muscle, while findings for cavernous angioleiomyomas were nonspecific. Thus, clinical findings and MR imaging were almost sufficient for preoperative diagnosis of solid and venous angioleiomyomas.

Abstract
The recent discovery that multiple species of shrews and moles (order Eulipotyphla, families Soricidae and Talpidae) from Europe, Asia, Africa and/or North America harbour genetically distinct viruses belonging to the family Hantaviridae (order Bunyavirales) has prompted a further exploration of their host diversification. In analysing thousands of frozen, RNAlater-preserved and ethanol-fixed tissues from bats (order Chiroptera) by reverse transcription polymerase chain reaction (RT-PCR), ten hantaviruses have been detected to date in bat species belonging to the suborder Yinpterochiroptera (families Hipposideridae, Pteropodidae and Rhinolophidae) and the suborder Yangochiroptera (families Emballonuriade, Nycteridae and Vespertilionidae). Of these, six hantaviruses are from Asia (Xuân Son virus and Dakrông virus in Vietnam; Láibin virus in China and Myanmar; Huángpí virus and Lóngquán virus in China; and Quezon virus in the Philippines); three are from Africa (Mouyassué virus in Côte d'Ivoire and Ethiopia; Magboi virus in Sierra Leone; and Makokou virus in Gabon); and one from Europe (Brno virus in the Czech Republic). Molecular identification of many more bat-borne hantaviruses is expected. However, thus far, none of these newfound viruses has been isolated in cell culture and it is unclear if they cause infection or disease in humans. Future research must focus on myriad unanswered questions about the genetic diversity and geographic distribution, as well as the pathogenic potential, of bat-borne viruses of the family Hantaviridae.

Abstract
Haemophilus influenzae type b (Hib) causes several invasive infections such as meningitis, septic arthritis, and pneumonia, especially in children below 5 years old. Despite the availability of Hib vaccines against Hib infection, seroepidemiological surveys of Hib infections have not yet been systematically conducted in Japan. We analyzed 1,338 serum samples, provided by the National Serum Reference Bank of the National Institute of Infectious Diseases (Tokyo, Japan), from 0- to 5-year-old children. Anti-polyribosylribitol phosphate (PRP) immunoglobulin G (IgG) antibody levels against Hib were determined using an anti-H. influenzae IgG enzyme immunoassay kit. In a total of 1,168 (87.3%) serum samples from children, anti-PRP IgG antibody levels were ≥ 0.15 μg/mL, providing natural immunity. Titers expected to provide long-term protection (≥ 1 μg/mL) were increased from 2.7% to 51.6% in children < 1 year old after the introduction of Hib vaccine (1980, 5.3%; 1995, 2.7%; 2010, 22%; 2012, 51.6%). Our data confirmed that the introduction of Hib vaccination in children below 5 years old increased the proportion of children having high anti-PRP IgG antibody levels, ensuring long-term protection against Hib.

Abstract
The recent discovery of genetically distinct shrew- and mole-borne viruses belonging to the newly defined family Hantaviridae (order Bunyavirales) has spurred an extended search for hantaviruses in RNAlater®-preserved lung tissues from 215 bats (order Chiroptera) representing five families (Hipposideridae, Megadermatidae, Pteropodidae, Rhinolophidae and Vespertilionidae), collected in Vietnam during 2012 to 2014. A newly identified hantavirus, designated Đakrông virus (DKGV), was detected in one of two Stoliczka’s Asian trident bats (Aselliscus stoliczkanus), from Đakrông Nature Reserve in Quảng Trị Province. Using maximum-likelihood and Bayesian methods, phylogenetic trees based on the full-length S, M and L segments showed that DKGV occupied a basal position with other mobatviruses, suggesting that primordial hantaviruses may have been hosted by ancestral bats.

Abstract
Few studies had been published regarding imaging findings of skin adnexal tumors. We experienced two giant cases of them with a characteristic mushroom-like growth pattern. MRI showed a circumscribed mushroom-like shaped mass extruding from the subcutaneous tissue with microcystic lesions. Although differentiation between benignancy and malignancy may be difficult by radiological examinations, MRI may be helpful to identify its origin and differentiate soft tissue tumors with skin adnexal tumors in having these imaging findings.

Abstract
Poroma is a benign skin tumor exhibiting terminal sweat gland duct differentiation. The present study aimed to explore the potential role of gene fusions in the tumorigenesis of poromas. RNA sequencing and reverse transcription PCR identified highly recurrent YAP1-MAML2 and YAP1-NUTM1 fusions in poromas (92/104 lesions, 88.5%) and their rare malignant counterpart, porocarcinomas (7/11 lesions, 63.6%). A WWTR1-NUTM1 fusion was identified in a single lesion of poroma. Fluorescent in-situ hybridization confirmed genomic rearrangements involving these genetic loci. Immunohistochemical staining could readily identify the YAP1 fusion products as nuclear expression of the N-terminal portion of YAP1 with a lack of the C-terminal portion. YAP1 and WWTR1, also known as YAP and TAZ, respectively, encode paralogous transcriptional activators of TEAD, which are negatively regulated by the Hippo signaling pathway. The YAP1 and WWTR1 fusions strongly transactivated a TEAD reporter and promoted anchorage-independent growth, confirming their tumorigenic roles. Our results demonstrate the frequent presence of transforming YAP1 fusions in poromas and porocarcinomas and suggest YAP1/TEAD-dependent transcription as a candidate therapeutic target against porocarcinoma.

Abstract
The discovery of highly divergent lineages of hantaviruses (family Hantaviridae) in shrews, moles, and bats of multiple species raises the possibility that non-rodent hosts may have played a significant role in their evolutionary history. To further investigate this prospect, total RNA was extracted from RNAlater®-preserved lung tissues of 277 bats (representing five families, 14 genera and 40 species), captured in Myanmar and Vietnam during 2013⁻2016. Hantavirus RNA was detected in two of 15 black-bearded tomb bats (Taphozous melanopogon) and two of 26 Pomona roundleaf bats (Hipposideros pomona) in Myanmar, and in three of six ashy leaf-nosed bats (Hipposideros cineraceus) in Vietnam. Pair-wise alignment and comparison of coding regions of the S, M, and L segments of hantaviruses from Taphozous and Hipposideros bats revealed high nucleotide and amino acid sequence similarities to prototype Láibīn virus (LAIV) and Xuân Sơn virus (XSV), respectively. Phylogenetic analyses, generated by maximum-likelihood and Bayesian methods, showed a geographic clustering of LAIV strains from China and Myanmar, but not of XSV strains from China and Vietnam. These findings confirm that the black-bearded tomb bat is the natural reservoir of LAIV, and that more than one species of Hipposideros bats can host XSV.

Polio vaccination coverage and seroprevalence of poliovirus antibodies after the introduction of inactivated poliovirus vaccines for routine immunization in Japan. Vaccine 2019; 37:1964-1971. [PMID: 30827736 DOI: 10.1016/j.vaccine.2019.02.034] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/19/2018] [Revised: 01/07/2019] [Accepted: 02/15/2019] [Indexed: 01/28/2023]
Abstract
In Japan, the oral poliovirus vaccine (OPV) was changed to 2 types of inactivated poliovirus vaccine (IPV), the standalone conventional IPV (cIPV) and the Sabin-derived IPV combined with diphtheria-tetanus-acellular pertussis vaccine (DTaP-sIPV), for routine immunization in 2012. We evaluated polio vaccination coverage and the seroprevalence of poliovirus antibodies using data from the National Epidemiological Surveillance of Vaccine-Preventable Diseases (NESVPD) from 2011 to 2015. Several years before the introduction of IPV in 2012, OPV administration for children was refused by some parents because of concerns about the risk of vaccine-associated paralytic poliomyelitis. Consequently, in children aged <1 years who were surveyed in 2011-2012, polio vaccination coverage (45.0-48.8%) and seropositivity rates for poliovirus (type 1: 51.7-65.9%, type 2: 48.3-53.7%, and type 3: 15.0-29.3%) were decreased compared to those surveyed in 2009. However, after IPV introduction, the vaccination coverage (95.5-100%) and seropositivity rates (type 1: 93.2-96.6%, type 2: 93.1-100%, and type 3: 88.6-93.9%) increased among children aged <1 years in 2013-2015. In particular, seropositivity rates and geometric mean titers (GMTs) for poliovirus type 3 in <5-year-old children who received 4 doses of IPV (98.5% and 247.4, respectively) were significantly higher than in those who received 2 doses of OPV (72.5% and 22.9, respectively). Furthermore, in <5-year-old children who received 4 doses of either DTaP-sIPV or cIPV, the seropositivity rates and the GMTs for all 3 types of poliovirus were similarly high (96.5-100% and 170.3-368.8, respectively). Our findings from the NESVPD demonstrate that both the vaccination coverage and seropositivity rates for polio remained high in children after IPV introduction.

Abstract
Background We conducted a randomized trial to evaluate the efficacy of heparinoid moisturization for radiation dermatitis. We report the time-course of sebum content after whole breast radiotherapy (WBRT) and the efficacy of heparinoid moisturizer. Methods Patients receiving adjuvant breast RT were randomly assigned into three groups; prophylaxis, post-WBRT and control groups. Patients used moisturizer on the irradiated breast from the beginning of RT in the prophylaxis group, 2 weeks post-RT in the post-WBRT group, and no moisturizer in the control group. Sebum content of the irradiated and non-irradiated breast was measured to assess sebaceous gland damage. Sebum composition was also analyzed. Results A total of 76 patients were analyzed; 30 in the post-WBRT group, 32 in the control group, 14 in the prophylaxis group. The sebum content in the irradiated breast significantly decreased after WBRT in the post-WBRT and control groups. The decrease was sustained in the control group. In the non-irradiated breast, sebum content also decreased after WBRT in the post-WBRT and control groups. After moisturizer application, sebum content by sebumeter returned to pre-RT level in the post-WBRT group, while the decrease was sustained in the control group. Sebum content measured by evaporative light scattering detector and sebumeter was similar in the control group, but the dissociation was observed after moisturizer application in the post-WBRT group. The proportion of wax esters decreased in the irradiated breast after WBRT. Conclusions Radiotherapy significantly reduced sebum content in both irradiated and non-irradiated breast, indicating that RT caused quantifiably persistent sebaceous gland damage in irradiated sites and the surrounding tissue. Combined with the results from our previous study, heparinoid moisturizer treatment effectively prevents water loss by retaining oil contents on the skin surface.

Abstract
A phase 3, multicenter, open-label, 52-week study investigated the efficacy and safety of adalimumab 80 mg at week 0 followed by adalimumab 40 mg every other week (option to escalate to 80 mg when necessary) in Japanese patients with generalized pustular psoriasis (GPP). Adults (aged 15-75 years) with GPP, total skin score (overall erythema area, erythema area with pustules, and edema area) of 3 or more, and erythema with pustules (skin score, ≥1) based on the 2014 Japanese Dermatological Association severity index of GPP were enrolled. The primary efficacy end-point was clinical response at week 16 (non-responder imputation), defined as achieving remission (total skin score, 0) or improvement from baseline (reduction of ≥1 point from a baseline total skin score of 3 or ≥2 points from a baseline total skin score of ≥4). Of 10 enrolled patients (mean disease duration, 10.6 years), seven patients, including three with the dose escalated to 80 mg every other week before week 15, achieved clinical response at week 16, and five achieved clinical response at week 52. Mean change from baseline total GPP score was -4.6 at week 16 (n = 8) and -6.0 at week 52 (n = 5); change in total skin score was -3.1 (n = 8) and -4.2 (n = 5), respectively. Nine patients experienced one or more adverse events and three experienced serious adverse events. The most common adverse events were nasopharyngitis, pruritus and hypoalbuminemia. In conclusion, adalimumab was effective and well tolerated for up to 52 weeks in the treatment of Japanese patients with GPP.
