Hepatitis B virus infection reactivation in patients under immunosuppressive therapies: Pathogenesis,screening, prevention and treatment

With a 5.3% of the global population involved, hepatitis B virus (HBV) is a major public health challenge requiring an urgent response. After a possible acute phase, the natural history of HBV infection can progress in chronicity. Patients with overt or occult HBV infection can undergo HBV reactivation (HBVr) in course of immunosuppressive treatments that, apart from oncological and hem-atological diseases, are also used in rheumatologic, gastrointestinal, neurological and dermatological settings, as well as to treat severe acute respiratory syndrome coronavirus 2 infection. The risk of HBV reactivation is related to the immune status of the patient and the baseline HBV infection condition. The aim of the present paper is to investigate the risk of HBVr in those not oncological settings in order to suggest strategies for preventing and treating this occurrence. The main studies about HBVr for patients with occult hepatitis B infection and chronic HBV infection affected by non-oncologic diseases eligible for immunosuppressive treatment have been analyzed. The occurrence of this challenging event can be reduced screening the population eligible for immunosuppressant to assess the best strategies according to any virological status. Further prospective studies are needed to increase data on the risk of HBVr related to newer immunomodulant agents employed in non-oncological setting.     

C-Reactive protein role in assessing COVID-19 deceased geriatrics and survivors of severe and critical illness

Numerous risk variables, including age, medical co-morbidities, and deranged inflammatory response, lead to higher mortality in a senior population with coronavirus disease 2019. C-reactive protein (CRP), an acute phase inflammatory protein secreted by the liver, was tested in the elderly, showing a diagnostic and prognostic role. However, recent research has shed light on new applications for CRP in geriatrics. It was used as a follow-up marker and as a therapeutic target. Early and accurate identification of patients' risks may mitigate the devastation of the invading virus in older cases and permit the implementation of a quick treatment plan for those most likely to deteriorate.     

Endodontics Specialists’ Practice during the Initial Outbreak of Coronavirus Disease 2019

IntroductionThe first outbreak of coronavirus disease 2019 (COVID-19) in the United States resulted in a nationwide closure of dental offices that created an oral health crisis. The aim of this observational study was to analyze and compare the characteristics of patients who visited 2 private endodontics offices from March 16 to May 31, 2020, compared with the same period in 2019.MethodsDemographic, diagnostic, and procedural data of 1520 (693 in 2020 and 827 in 2019) patient visits were collected. Bivariate and multiple logistic regression analyses were used to assess the impact of the COVID-19 outbreak on patient-related variables.ResultsBivariate analyses showed that the number of patient visits decreased in April and May 2020 (P < .0001). In 2020, patients’ self-reported pain level was higher, they were more frequently diagnosed with pulp necrosis and acute apical abscess, and they received more incisions for drainage (P < .05). Multiple logistic regression analyses showed that the COVID-19 outbreak was associated with less visits for older patients (>49.5 years) (odds ratio [OR] = 0.720; 95% confidence interval [CI], 0.573–0.906), more patients with kidney diseases (OR = 2.690; 95% CI, 1.143–6.331), higher levels of pain on percussion (OR = 2.277; 95% CI, 1.718–3.016), less cases with previously initiated treatment (OR = 0.242; 95% CI, 0.080–0.731), less periapical diagnoses of asymptomatic apical periodontitis (OR = 0.510; 95% CI, 0.306–0.849), and a higher number of nonsurgical root canal treatments (OR = 2.073; 95% CI, 1.397–3.074) and apicoectomies (OR = 2.799; 95% CI, 1.367-5.729).ConclusionsThese findings show that the public health burden of endodontic infections was more intense during the initial outbreak of COVID-19.     

2006—2020年四川省疾病预防控制中心因公出国(境)任务现状分析及发展建议

目的回顾四川省疾病预防控制中心"十一五""十二五""十三五"期间因公出国(境)任务现状,为强化新时期疾病预防控制国际交流与合作提供依据和建议。方法通过Excel 2013软件录入2006—2020年的因公出国(境)档案资料并建立数据库,从任务类型、业务领域、出访国家(地区)、经费来源等方面进行描述性分析。结果2016—2020年("十三五")四川省疾控中心因公出国(境)共223人次,2011—2015年("十二五")较2006—2010年("十一五")下降14.29%,2016—2020年较2011—2015年下降51.19%,实地考察出访人次2016—2020年较2006—2010年下降80%,任务占比下降约52.18%;业务领域方面,传染性疾病防治领域出访129人次(57.85%),非传染性慢性疾病防治14人次(6.28%)、卫生检验10人次(4.48%)、免疫规划8人次(3.59%);出访高收入国家(地区)人次"十三五"时期较"十一五"时期下降76.47%,占比下降43.76%,对外援助增加7人次。结论2006—2020年四川省疾控中心因公出国(境)出访人次总体呈下降趋势,实地考察任务下降幅度最大;出访任务集中于传染性疾病防治领域,在业务领域分布上存在较为明显的比例失衡现象;出访高收入国家(地区)人次(占比)下降,对外援助大幅增加。

基于DEA方法的华法林抗凝分级管理模式的效率评价

目的:通过小范围的临床实践,使用数据包络分析(data envelopment analysis,DEA)方法对基于全程化抗栓药学服务模式的华法林抗凝管理工作效率进行评价。方法:选取2021年7-12月南京大学医学院附属鼓楼医院心胸外科瓣膜置换术后使用华法林抗凝的患者。将患者分为实验组和对照组,实验组由临床药师利用基于分级管理的全程化抗栓药学服务模式进行抗凝管理和药学监护,对照组由临床药师按照无差别监护模式进行抗凝管理和监护,记录2种模式下药师工作内容和工作成效,通过DEA方法分析比较2种抗凝管理模式的效率。结果:研究最终纳入服用华法林的患者233人(实验组116人,对照组117人),实验组的单位患者管理时间显著减少[(27.8±9.7)min vs.(34.8±11.4)min]。经模型计算后,实验组的总体效率值为1,说明其投入和产出最优,且效率高于对照组。结论:全程化抗栓药学服务模式下药师管理单位抗凝患者需要的时间更少,管理效率更高。
