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.

Understanding Hispanic Patient Satisfaction with Telehealth During COVID-19

BackgroundRecent studies have described the use of telehealth for pediatric surgical care during the COVID-19 pandemic. We aimed to evaluate equity in telehealth use by comparing rates of utilization and satisfaction with pediatric surgical telemedicine among Hispanic patients.MethodsWe conducted a retrospective cohort study of patients seen by a surgical subspecialty provider in the outpatient setting at a quaternary pediatric hospital between April 1 and June 30, 2020. Patients evaluated in the same three-month period in 2019 were analyzed as a historic control. Differences in Family Experience Survey (FES) responses based on race and ethnicity and preferred language of care were assessed using univariable and multivariable generalized linear modeling.ResultsThe pandemic cohort included fewer patients of Hispanic ethnicity and fewer Spanish-speakers. After controlling for visit type, comparison of Spanish-speaking and English-speaking patients revealed that Spanish-speaking families had significantly lower scores for FES items that evaluated healthcare provider explaining (IRR 0.74, 95% CI: 0.61–0.90), listening (IRR 0.76, 95% CI: 0.63–0.92), and time spent with the family (IRR 0.73, 95% CI: 0.60–0.89). There were no differences in FES responses based on insurance status or degree of medical complexity.ConclusionsTelehealth services were less commonly used among Hispanic and Spanish-speaking patients. Language may differentially affect family satisfaction with healthcare and telehealth solutions. Strategies to mitigate these inequities are needed and may include strengthening interpreter services and providing language-concordant care.Level of evidenceLevel IV.     

大黄附子汤对重症急性胰腺炎小鼠肠道微皱褶细胞变化的影响

目的研究大黄附子汤对重症急性胰腺炎(SAP)小鼠肠道微皱褶细胞(M细胞)变化的影响，为大黄附子汤临床防治SAP提供理论基础。 方法选取40只健康SPF级C57BL/6J雄性小鼠，随机分为4组(每组10只)：空白对照组、大黄附子汤对照组、SAP组、大黄附子汤治疗组，其中SAP组和大黄附子汤治疗组分别以3.5 g/kg剂量腹腔注射20% L-精氨酸，空白对照组和大黄附子汤对照组注射等剂量的等渗盐水；于造模后12、24、36 h，空白对照组和SAP组给予等渗盐水0.2 mL，大黄附子汤对照组和治疗组给予大黄附子汤0.2 mL灌肠，均于造模完成48 h后处死取材，使用ELISA检测血清淀粉酶、内毒素、IL-1β及TNF-α含量，取回肠及胰腺组织行HE染色、评分，免疫组化染色检测M细胞特异性蛋白GP2并评分。 结果(1)一般情况：对照组腹腔注射后小鼠一般情况好，精神状态良好，能正常进水，四肢活动自如，行动未受影响；SAP组小鼠腹腔注射后一般情况差，精神萎靡，反应迟钝，行动迟缓，呼吸急促，拱背收腹，饮水减少。(2)SAP组淀粉酶、内毒素、IL-1β及TNF-α水平较对照组明显升高(P<0.05)；与SAP组进行对比，大黄附子汤治疗组血清淀粉酶、内毒素、IL-1β及TNF-α水平出现显著下降(P<0.05)。(3)HE染色：SAP组胰腺及回肠组织坏死严重，可见大量白细胞浸润。大黄附子汤治疗组胰腺及回肠组织轻度坏死，可见少量中性粒细胞等白细胞浸润。(4)免疫组化染色：SAP组与对照组相比GP2表达降低(P<0.05)；相较于SAP组，大黄附子汤治疗组GP2的表达水平升高(P<0.05)。 结论大黄附子汤治疗可改善作为肠道免疫应答起始的M细胞数量与功能，增强肠道免疫应答，减轻肠免疫屏障损伤，减少内毒素入血，改善SAP症状。

The impact of the COVID-19 pandemic on hepatitis B virus vaccination and transmission among men who have sex with men: A mathematical modelling study

BackgroundDuring the COVID-19 pandemic, the number of hepatitis B virus (HBV) vaccinations among men who have sex with men (MSM) has been considerably lower than before the pandemic. Moreover, less frequent HBV testing and a reduction in numbers of sex partners have been reported. We assessed the impact of these COVID-19-related changes on HBV transmission among MSM in the Netherlands.MethodsWe estimated the changes in sexual activity, HBV testing, and HBV vaccination among MSM during the pandemic from Dutch data. We used a deterministic compartmental model and investigated scenarios with small or large declines in sexual activity, testing, and vaccination for the current phase of the pandemic (without available data). We examined the increase in HBV vaccinations needed to prevent further increase in HBV incidence.ResultsWith a decrease in numbers of sex partners of 15–25% during the first lockdown and 5% during the second lockdown, we found a decline of 6.6% in HBV incidence in 2020, despite a >70% reduction in HBV testing and vaccination during the first lockdown. With numbers of sex partners rebounding close to pre-pandemic level in 2021, and a reduction of 15% in testing and 30% in vaccination in 2021, we found an increase of 1.4% in incidence in 2021 and 3.1% in 2026. With these changes, an increase of ≥60% in HBV vaccinations in 2022 would be needed to bring the HBV incidence in 2023 back to the level that it would have had if the COVID-19-related changes had not occurred.ConclusionsDespite reductions in sexual activity during the COVID-19 pandemic, the decrease in HBV vaccinations may result in a small increase in HBV incidence after 2021, which may persist for years. It is important to restore the vaccination level and limit further increase in HBV transmission among MSM.     

Efficacy of an eConsult service to cure hepatitis C in primary care

In 2016, an eConsult service was developed within a safety net health system to expand access to hepatitis C (HCV) treatment in the primary care setting. The eConsult system provides individualized treatment recommendations from specially trained primary care pharmacists and primary care physicians to primary care providers with less experience in the rapidly changing treatment of HCV. Since its launch, this service has had a large impact in expanding care to a largely homeless and low-income urban population within our health system. We now aim to evaluate its efficacy in curing HCV. In this retrospective cohort study, we describe rates of sustained virologic response 12 weeks after treatment completion (SVR12) for those who received primary care-based HCV treatment through the eConsult system with those who were treated in primary care independent of an eConsult from 2017 to 2019. We found there was no significant difference in the proportion of patients who achieved SVR12 between the two groups. Overall, >90% of patients who received treatment achieved SVR12. Approximately 40% of patients treated for HCV received an eConsult, suggesting utility of the eConsult in expanding access and coordinating treatment for patients within our network.     

纤维支气管镜在PICU重症肺炎患儿治疗中的效果分析

目的分析纤维支气管镜应用于PICU重症肺炎患儿治疗中的效果。方法将我院于2019年9月至2021年6月收治的80例重症肺炎患儿分为2组,即观察组和对照组,对照组予以抗生素、氧疗、止咳祛痰等常规治疗,观察组另予纤维支气管镜灌洗治疗,观察疗效、住院天数、总热程、肺部感染评分(CPIS)变化、白细胞计数(WBC)变化、咳嗽好转时间、啰音消失时间等,统计灌洗治疗前后并发症;择取两组致病菌均为腺病毒患儿进行二次分组--灌洗组及未灌洗组,比较两组疗效、咳嗽好转时间、啰音消失时间、住院时间、总热程,观察支气管镜对腺病毒感染者治疗效果。结果观察组疗效优于对照组,差异存在统计学意义(P<0.05);灌洗组疗效与未灌洗组基本相当(P>0.05)。观察组WBC、CPIS得分均显著低于对照组,总热程、咳嗽有效控制时间、肺部湿啰音消失时间、住院总天数均明显短于对照组,差异均具有统计学意义(P<0.05);灌洗组咳嗽控制时间短于未灌洗组(P<0.05),但总热程、啰音消失时间及住院天数与未灌洗组比较无统计学差异(P>0.05)。灌洗并发症发生率为20.00%,均好转。结论PICU重症肺炎患儿应用纤维支气管镜治疗安全可靠,能明显改善患儿当前症状,但对腺病毒导致的重症肺炎收效甚微。     

Organoids in modelling infectious diseases

Approaches based on animal and two-dimensional (2D) cell culture models cannot ensure reliable results in modeling novel pathogens or in drug testing in the short term; therefore, there is rising interest in platforms such as organoids. To develop a toolbox that can be used successfully to overcome current issues in modeling various infections, it is essential to provide a framework of recent achievements in applying organoids. Organoids have been used to study viruses, bacteria, and protists that cause, for example, respiratory, gastrointestinal, and liver diseases. Their future as models of infection will be associated with improvements in system complexity, including abilities to model tissue structure, a dynamic microenvironment, and coinfection.Teaser.Organoids are a flexible tool for modelling viral, bacterial and protist infections. They can provide fast and reliable information on the biology of pathogens and in drug screening, and thus have become essential in combatting emerging infectious diseases.
