    目的:为了确定NPC的发病率和生存率的趋势,按EBV状态和组织病理学亚型细分,在荷兰的30年。
    方法:来自荷兰癌症登记处和荷兰全国病理学数据库(PALGA)的1989-2018年期间的匿名数据被链接以识别和分类NPC病例。
    结果:NPC的发病率保持稳定,年百分比变化(APC)为-0.2。(95%CI-0.9;0.5)。EBV测试仅在过去十年中成为常规,在此期间,EBV阳性肿瘤的发病率保持稳定(APC1.2,95%CI-1.3;3.8).发现EBV阴性肿瘤增加(APC:7.1,95%CI2.5;11.9)和未测试肿瘤减少(APC:-10.7,95%CI-15.7;-5.7)。非角质化的发生率,分化肿瘤增加(APC:3.8,(95%CI2.2;5.5),而其他组织学亚型的发生率保持稳定.1998年以后诊断的患者的总生存率较好(风险比0.8,95%CI0.6;0.9)。EBV状态,组织学,舞台,和年龄与相对超额死亡风险独立相关,但诊断期没有。
    结论:EBV测试随着时间的推移而增加,在过去的10年中,EBV阳性NPC的发病率稳定。非角化的发病率上升,分化的NPC反映了来自美国的数据,并暗示了非流行地区的转变。
    OBJECTIVE: To identify trends in incidence and survival of NPC, subdivided by EBV status and histopathological subtype, over a 30-year period in the Netherlands.
    METHODS: Anonymized data from the Netherlands Cancer Registry and the Dutch Nationwide Pathology Databank (PALGA) for the period 1989-2018 were linked to identify and classify NPC cases.
    RESULTS: Incidence of NPC remained stable, with an annual percentage change (APC) of - 0.2. (95% CI - 0.9; 0.5). EBV testing became routine only in the last decade, the incidence of EBV-positive tumors remained stable over this period (APC 1.2, 95% CI - 1.3; 3.8). An increase in EBV-negative tumors (APC: 7.1, 95% CI 2.5; 11.9) and a decrease in untested tumors were found (APC: - 10.7, 95% CI - 15.7; - 5.7). The incidence of non-keratinizing, differentiated tumors increased (APC: 3.8, (95% CI 2.2; 5.5) while the incidence of other histological subtypes remained stable. Overall survival was better in patients diagnosed after 1998 (hazard ratio 0.8, 95% CI 0.6; 0.9). EBV status, histology, stage, and age were independently associated with relative excess risk of dying, but period of diagnosis was not.
    CONCLUSIONS: Testing for EBV increased over time, and a stable incidence of EBV-positive NPC over the last 10 years. The rising incidence of non-keratinizing, differentiated NPC mirrors data from the US and suggests a shift in non-endemic regions.

    对人类嗜T淋巴细胞病毒(HTLV)的理解仍主要基于流行地区的流行病学和临床数据。全球化导致患有HTLV(PLHTLV)的人从流行地区迁移到非流行地区,以及美国HTLV感染的上升。然而,由于这种疾病的历史罕见,受影响的患者通常诊断不足和错误。因此,我们试图描述流行病学的特征,临床特征,合并症,以及在非流行区确定的HTLV-1或HTLV-2阳性个体的存活率。
    我们的研究是一个单一的机构,1998年至2020年HTLV-1或HTLV-2患者的回顾性病例对照分析。我们使用了两个HTLV阴性对照,年龄相匹配,性别,和种族,对于每个HTLV阳性病例。我们评估了HTLV感染与几种血液学,神经学,传染性,和风湿病协变量。最后,评估了预测总生存期(OS)的临床因素.
    我们确定了38例HTLV感染,其中23例为HTLV-1,15例为HTLV-2阳性。我们对照组中的大多数患者(约54%)接受了HTLV测试以进行移植评估,与约24%的HTLV血清阳性患者相比。与HTLV相关的共病,与对照组相比,HTLV血清阳性患者的丙型肝炎血清阳性率更高(OR10.7,95%CI=3.2-59.0,p<0.001).丙型肝炎和HTLV共感染导致OS降低,与没有感染相比,仅丙型肝炎感染,或单独的HTLV感染。与患有癌症或单独的HTLV的患者相比,患有任何癌症诊断和HTLV感染的患者的OS更差。与HTLV-2患者相比,HTLV-1阳性患者的中位OS较低(47.7个月与77.4个月)。在单变量分析中,HTLV血清阳性患者的1年全因死亡率风险增加,成人T细胞白血病,急性骨髓性白血病,和丙型肝炎感染。更正后,多变量分析显示,HTLV血清阳性与1年全因死亡率不再相关;然而与AML和丙型肝炎感染的相关性仍然显著。
    在多变量分析中,HTLV血清阳性与1年死亡率增加无关。然而,我们的研究受到患者样本量小的限制,以及由于HTLV测试的选择因素而导致的偏倚患者对照人群。
    UNASSIGNED: Understanding of human T-lymphotropic virus (HTLV) remains largely based on epidemiologic and clinical data from endemic areas. Globalization has resulted in migration of persons living with HTLV (PLHTLV) from endemic to non-endemic areas, and a rise of HTLV infection in the United States. Yet, due to the historical rarity of this disease, affected patients are often under- and mis-diagnosed. Thus, we sought to characterize the epidemiology, clinical features, comorbidities, and survival of HTLV-1- or HTLV-2-positive individuals identified in a non-endemic area.
    UNASSIGNED: Our study was a single institution, retrospective case-control analysis of HTLV-1 or HTLV-2 patients between 1998 and 2020. We utilized two HTLV-negative controls, matched for age, sex, and ethnicity, for each HTLV-positive case. We evaluated associations between HTLV infection and several hematologic, neurologic, infectious, and rheumatologic covariates. Finally, clinical factors predictive of overall survival (OS) were assessed.
    UNASSIGNED: We identified 38 cases of HTLV infection, of whom 23 were HTLV-1 and 15 were HTLV-2 positive. The majority (~54%) of patients in our control group received HTLV testing for transplant evaluation, compared to ~24% of HTLV-seropositive patients. Co-morbidities associated with HTLV, hepatitis C seropositivity were higher in HTLV-seropositive patients compared to controls (OR 10.7, 95% CI = 3.2-59.0, p < 0.001). Hepatitis C and HTLV co-infection resulted in decreased OS, compared to no infection, hepatitis C infection alone, or HTLV infection alone. Patients with any cancer diagnosis and HTLV infection had worse OS compared to patients with cancer or HTLV alone. HTLV-1 positive patients had lower median OS compared to HTLV-2 patients (47.7 months vs. 77.4 months). In univariate analysis, the hazard for 1-year all-cause mortality was increased among patients with HTLV-seropositivity, adult T-cell leukemia, acute myelogenous leukemia, and hepatitis C infection. When corrected, multivariate analysis showed that HTLV seropositivity was no longer associated with 1 year all-cause mortality; however association with AML and hepatitis C infection remained significant.
    UNASSIGNED: HTLV-seropositivity was not associated with increased 1 year mortality in multivariate analysis. However, our study is limited by our small patient sample size, as well as the biased patient control population due to selection factors for HTLV testing.

    尽管全球报告了霍乱暴发的数量,在返回的欧洲旅行者中只有少数案例被记录。我们描述了一个41岁男性的案例,在孟加拉国逗留后返回意大利,他的原籍国,出现水样腹泻的人。通过多重PCR方法检测患者粪便中的霍乱弧菌和诺如病毒。直接显微镜,革兰氏染色,进行了培养和抗生素药敏试验.使用终点PCR对分离物进行测试,以检测潜在的肠致病性霍乱弧菌。进行血清型和霍乱毒素鉴定。进行全基因组测序和生物信息学分析,并鉴定了抗菌素抗性基因。建立了具有先前描述的数据库的最相似基因组的系统发育树。还收集并分析了患者带回的食物样品。患者被诊断为霍乱弧菌O1,血清型Inaba,诺如病毒和SARS-CoV-2合并感染。发现分离的霍乱弧菌菌株属于ST69,编码霍乱毒素,ctxtB7型,与2018年达卡爆发的系统发育相关,孟加拉国。在非霍乱流行国家采用多学科方法确保了快速准确的诊断,及时的临床管理,以及国家和国际层面的流行病学调查。
    Despite the number of cholera outbreaks reported worldwide, only a few cases are recorded among returning European travellers. We describe the case of a 41-year-old male, returning to Italy after a stay in Bangladesh, his origin country, who presented with watery diarrhoea. Vibrio cholerae and norovirus were detected in the patient\'s stools via multiplex PCR methods. Direct microscopy, Gram staining, culture and antibiotic susceptibility tests were performed. The isolates were tested using end-point PCR for the detection of potentially enteropathogenic V. cholera. Serotype and cholera toxins identification were carried out. Whole genome sequencing and bioinformatics analysis were performed, and antimicrobial resistance genes identified. A phylogenetic tree with the most similar genomes of databases previously described was built. Sample of the food brought back by the patient were also collected and analysed. The patient was diagnosed with V. cholerae O1, serotype Inaba, norovirus and SARS-CoV-2 concomitant infection. The isolated V. cholerae strain was found to belong to ST69, encoding for cholera toxin, ctxB7 type and was phylogenetically related to the 2018 outbreak in Dhaka, Bangladesh. Adopting a multidisciplinary approach in a cholera non-endemic country ensured rapid and accurate diagnosis, timely clinical management, and epidemiological investigation at national and international level.

    最近在没有这种疾病流行的国家报告了许多猴痘病例,引起全球健康关注。因此,医疗保健专业人员(HCP),包括药剂师,需要意识到这种疾病,其预防,包括疫苗的作用,及其管理以减少传播。横截面,在沙特阿拉伯Qassim地区方便抽样的社区药剂师中进行了基于问卷的研究。共有189名社区药剂师参与研究,反应率为72.97%。从这些,86.77%为男性,51.32%≤30岁,36.51%的人年龄在31-40岁之间,43.39%有1-5年的社区药剂师经验。他们的总体知识为17.72±5.56,最高28。知识陈述的总体正确答案率为63.29%,52.4%答对≥50-<75%的知识题,31.2%答对≥75%的知识题。与诊断和临床特征相关的知识子领域得分最高,与致病病原体和流行病学相关的子领域得分较低。总的来说,社区药剂师对猴痘及其临床管理有一定的了解,预防,以及疫苗的作用,这是对未来的关注。因此,量身定做,灵活,需要及时的教育干预,以确保HCPs,包括社区药剂师,完全具备关于这种病毒性疾病的最新循证知识,以减少传播和改善护理。
    Many cases of monkeypox have recently been reported in countries where this disease is not endemic, raising a global health concern. Consequently, healthcare professionals (HCPs), including pharmacists, need to be aware of the disease, its prevention, including the role of vaccines, and its management to reduce transmission. A cross-sectional, questionnaire-based study was conducted among conveniently sampled community pharmacists in the Qassim region of Saudi Arabia. A total of 189 community pharmacists participated in the study, giving a response rate of 72.97%. From these, 86.77% were male, 51.32% were ≤30 years old, 36.51% were aged between 31-40 years, and 43.39% had 1-5 years of experience as community pharmacists. Their overall knowledge was 17.72 ± 5.56 out of a maximum of 28. The overall rate of correct answers for the knowledge statements was 63.29%, with 52.4% answering ≥50-<75% of the knowledge questions correctly and 31.2% answering ≥75% of the questions correctly. The knowledge subdomain related to diagnosis and clinical characteristics recorded the highest score, with the subdomain relating to causative pathogens and epidemiology recording a lower score. Overall, community pharmacists had moderate knowledge of monkeypox and its clinical management, prevention, and the role of vaccines, which is a concern for the future. Consequently, tailored, flexible, and timely educational interventions are needed to ensure that HCPs, including community pharmacists, are fully equipped with the latest evidence-based knowledge regarding this viral disease to reduce transmission and improve care.

    UNASSIGNED:在当前全局方案中,猴痘病毒已经感染了来自尼日利亚等流行国家的3000多人,以及像英国这样的非地方病国家,加拿大,美国,等。根据目前的信息,据观察,猴痘病例主要有,虽然不是唯一的,在英国等国家的男男性行为者(MSM)中发现。本文讨论了最近爆发的猴痘,其原因,以及对抗猴痘感染的各种方法。
    UNASSIGNED:我们评估了最近不同国家猴痘暴发的趋势,并将其与COVID-19大流行的开始方式进行了比较。
    未经批准:目前,据报道,猴痘通过皮肤与皮肤接触传播到58多个国家,体液,被污染的床单,服装,或呼吸路径。天花疫苗已被证明对猴痘具有85%的功效。为了缓解目前的疫情,世卫组织敦促人们实行良好的卫生习惯和安全性行为。更多病例的记录和进一步在成员国国家的传播最有可能再次发生,如果没有包含,我们可能会经历另一场全球大流行。因此,需要更多的研究来避免这个问题。
    未经授权:猴痘病毒正在测试我们是否遵守了COVID-19大流行的经验教训,并阐明了了解猴痘病所需研究的紧迫性。
    UNASSIGNED: In the current global scenario, the monkeypox virus has infected over 3000 individuals from endemic countries like Nigeria, along with non-endemic countries like the UK, Canada, the USA, etc. Based on the current information, it has been observed that monkeypox cases have primarily, though not exclusively, been found among men who have sex with men (MSM) in countries such as the UK. This article discusses the recent outbreak of monkeypox, its causes, and the various approaches to combat monkeypox infections.
    UNASSIGNED: We evaluated the trends of recent outbreaks of monkeypox in different countries and compared them to how the COVID-19 pandemic started.
    UNASSIGNED: At present, monkeypox has been reported to spread to over 58 countries via skin-to-skin contact, body fluids, contaminated bed sheets, clothing, or respiratory routes. Smallpox vaccines have been proven to have 85% efficacy against monkeypox. To mitigate this current outbreak, WHO urges people to practice good hygiene and safe sex. The documentation of more cases and further onward spread in the countries in member states are most likely to reoccur, and if not contained, we might experience another global pandemic. Therefore, more research is required to avert this problem.
    UNASSIGNED: Monkeypox virus is testing if we have complied with COVID-19 pandemic lessons and elucidates the urgency of research required to understand the monkeypox disease.

    在非流行地区的无症状高风险受试者中,对推荐的血吸虫病筛查算法缺乏共识。这项研究的目的是评估直接显微镜和ELISA血清学在非地方病环境中的高危人群中进行血吸虫病筛查的实际表现。2014年至2017年,在巴塞罗那(西班牙)的两个门诊热带医学单位进行了一项回顾性队列研究。包括来自撒哈拉以南地区的无症状成年人。根据临床实践,在每种情况下都采用不同的策略进行血吸虫病筛查:(A)如果存在无解释的嗜酸性粒细胞增多,则进行粪便和尿液直接检查加上曼氏链球菌血清学;(B)曼氏链球菌血清学加上尿寄生虫检查作为第二步。血清学阳性。人口统计,收集临床和实验室特征。血吸虫病病例,记录每组的临床管理和24个月的随访情况.包括四十四个人。患者主要来自西非国家。检出血吸虫病50例(A组11.5%vs.4%B组,p=0.733)。当进行显微镜和血清学技术时,结果不一致的占18.4%(16/88)。血吸虫病病例较年轻(p&lt;0.001),更频繁地出现嗜酸性粒细胞增多和IgE升高(p&lt;0.001)。血吸虫病是高危人群中的常见诊断。血清学在高危人群中的血吸虫病筛查中具有与直接诊断相似的性能。
    A consensus on the recommended screening algorithms for schistosomiasis in asymptomatic high-risk subjects in non-endemic areas is lacking. The objective of this study was to evaluate the real-life performance of direct microscopy and ELISA serology for schistosomiasis screening in a high-risk population in a non-endemic setting. A retrospective cohort study was conducted in two out-patient Tropical Medicine units in Barcelona (Spain) from 2014 to 2017. Asymptomatic adults arriving from the Sub-Saharan region were included. Schistosomiasis screening was conducted according to clinical practice following a different strategy in each setting: (A) feces and urine direct examination plus S. mansoni serology if non-explained eosinophilia was present and (B) S. mansoni serology plus uroparasitological examination as the second step in case of a positive serology. Demographic, clinical and laboratory features were collected. Schistosomiasis cases, clinical management and a 24 month follow-up were recorded for each group. Four-hundred forty individuals were included. The patients were mainly from West African countries. Fifty schistosomiasis cases were detected (11.5% group A vs. 4 % group B, p = 0.733). When both microscopic and serological techniques were performed, discordant results were recorded in 18.4% (16/88). Schistosomiasis cases were younger (p < 0.001) and presented eosinophilia and elevated IgE (p < 0.001) more frequently. Schistosomiasis is a frequent diagnosis among high-risk populations. Serology achieves a similar performance to direct diagnosis for the screening of schistosomiasis in a high-risk population.

    UNASSIGNED:鼻咽癌(NPC)在英国很少见。本研究的目的是调查非流行地区30个部位使用65Gy进行(化学)放射疗法治疗的NPC患者的生存结果。
    UNASSIGNED:在2009年1月至2019年6月期间诊断为非转移性鼻咽癌的所有连续62例患者均纳入本回顾性分析。
    未经评估:中位年龄为59岁(范围:19-81)。大多数患者患有III期疾病(66.1%)。21%的患者接受了诱导化疗,82.3%的患者同时接受全身治疗。所有患者均以65Gy分30次进行治疗。17.4%的患者出现疾病复发。5年无病,疾病特异性和总生存率为81.9%,79.2%和76.4%,分别。在单变量分析中,疾病复发与N分期(p=0.047)和整体分期组(p=0.023)相关.
    未经授权:尽作者所知,这是首次报道在真实世界中,在NPC中30次放疗±每周一次的顺铂化疗中使用65Gy.我们的结果与使用(化学)放射疗法的不同剂量分割的世界其他非流行地区的结果相当。未来的随机对照试验有必要比较这些设置中的各种剂量分级。
    UNASSIGNED: Nasopharyngeal carcinoma (NPC) is rare in the UK. The aim of the current study was to investigate survival outcomes for patients with NPC treated with (chemo)radiotherapy using 65 Gy in 30 fractions in a non-endemic region.
    UNASSIGNED: All consecutive 62 patients with histology proven non-metastatic nasopharyngeal carcinoma diagnosed between January 2009 to June 2019 were included in this retrospective analysis.
    UNASSIGNED: Median age was 59 years (range:19-81). The majority of patients had stage III disease (66.1%). Induction chemotherapy was given in 21% of patients and 82.3% of patients received concomitant systemic therapy. All patients were treated with 65 Gy in 30 fractions. There was disease recurrence in 17.4% patients. The 5-year disease-free, disease-specific and overall survival were 81.9%, 79.2% and 76.4%, respectively. On univariate analysis, disease recurrence was associated with N-stage (p = 0.047) and overall stage group (p = 0.023).
    UNASSIGNED: To the best of authors\' knowledge, this is the first report of the use of 65 Gy in 30 fractions of radiotherapy ± weekly cisplatin chemotherapy in NPC in a real-world setting. Our results are comparable to that from other non-endemic regions of the world using different dose fractionation of (chemo)radiotherapy. Future randomised control trials are warranted to compare various dose fractionations in these settings.
