Introduction

Both high- and low-income countries reported increased antibiotic consumption among COVID-19 patients during the first months of the pandemic. To date, however, no studies have examined changes in antibiotic consumption during the COVID-19 pandemic within humanitarian emergency contexts.

Method

Data was collected by Médecins Sans Frontières (MSF) for the years 2018–2021 across the following humanitarian settings: Afghanistan (Lashkar Gah), Bangladesh (Kutupalong), the Democratic Republic of Congo (Mweso and Baraka), and South Sudan (Bentiu). Inpatient and outpatient antibiotic consumption was calculated as Daily Defined Dose (DDD) per 1000 inhabitants per day, as per the World Health Organisation's (WHO) Collaborating Centre for Drug Statistics Methodology. Interrupted time series (ITS) analysis, using an autoregressive integrated moving average (ARIMA) model was used to analyse retrospective monthly antibiotic consumption. The impact of COVID-19 pandemic was evaluated as total antibiotic consumption and according to WHO Access, Watch, Reserve (AWaRe) group classifications within each humanitarian setting.

Results

The COVID-19 pandemic had no statistically significant impact on total antibiotic consumption in South Sudan (Bentiu) and Bangladesh (Kutupalong). Similarly, the pandemic had no impact on total antibiotic consumption in DR Congo (Baraka), despite an initial 0.27% (estimate=.274, p-value=0.006) increase in March 2020 driven by Access group antibiotics. Meanwhile, total antibiotic consumption in DR Congo (Mweso) and Afghanistan (Lashkar Gah) declined by 0.74% (estimate = −.744, p = 0.003) and 0.26% (estimate = −.26, p < 0.001), respectively with the COVID-19 pandemic.

Conclusion

Further studies are required to investigate what may have contributed to these results.

导言在COVID-19大流行的最初几个月中,高收入国家和低收入国家都报告称COVID-19患者的抗生素消耗量有所增加。无国界医生组织(MSF)收集了2018-2021年在以下人道主义环境中的数据:阿富汗(拉什卡尔加)、孟加拉国(库图帕隆)、印度(拉什卡尔加):阿富汗(拉什卡尔加)、孟加拉国(库图帕隆)、刚果民主共和国(姆韦索和巴拉卡)和南苏丹(本提乌)。根据世界卫生组织(WHO)药物统计合作中心的方法,住院病人和门诊病人的抗生素消耗量按每千人每日定义剂量(DDD)计算。采用自回归综合移动平均(ARIMA)模型进行间断时间序列(ITS)分析,对每月抗生素消耗量进行回顾性分析。结果COVID-19大流行对南苏丹(本提乌)和孟加拉国(库图帕隆)的抗生素总消耗量没有显著的统计学影响。同样,大流行对刚果民主共和国(巴拉卡)的抗生素总消费量也没有影响,尽管在 2020 年 3 月,在获取组抗生素的推动下,抗生素总消费量最初增加了 0.27%(估计值=0.274,P 值=0.006)。同时,刚果(金)和阿富汗(拉什卡尔加)的抗生素总消费量在 COVID-19 大流行时分别下降了 0.74%(估计值=-.744,P=0.003)和 0.26%(估计值=-.26,P< 0.001)。

SARS-CoV-2 surveillance in a hospital and control of an outbreak on a geriatric ward using whole genome sequencing 利用全基因组测序监测一家医院的 SARS-CoV-2 并控制老年病房的疫情爆发
IF 1.8 Q3 INFECTIOUS DISEASES Pub Date : 2024-07-06 DOI: 10.1016/j.infpip.2024.100383

Background

During the SARS-CoV-2 pandemic, dominant viral variants were repeatedly replaced by new variants with altered properties, frequently changing the dynamics of the infection event, as well as the effectiveness of vaccines and therapeutics. SARS-CoV-2 variant monitoring by whole genome sequencing was established at the University Medical Center Mainz, Germany to support patient management during the pandemic.

Methods

SARS-CoV-2 RNA samples from the University Medical Center were analysed weekly with whole genome sequencing. The genome sequences obtained were aligned with sequences from public databases to perform variant assignment. For classification purposes, phylogenetic trees were constructed to map the variant distribution in the clinical settings and the current outbreak events at that time. We describe the surveillance procedures using an example from a geriatric ward.

Results

For monitoring, a time series was created covering two years of the pandemic. The changes from the Alpha to the Delta and the Omicron variants of SARS-CoV-2 could thus be precisely observed. The increasingly rapid switch of Omicron subvariants in the recent past could be tracked. The elucidation of phylogenetic relationships between circulating strains allowed conclusions about transmission pathways. Using an example from a geriatric ward, we demonstrated how variant monitoring by whole genome sequencing supported the infection prevention and control procedures on a ward and contribute to the control of outbreaks.

Conclusions

This example of SARS-CoV-2 demonstrates the effectiveness of targeted, local monitoring by molecular variant analysis. The program proved to be instrumental in controlling an outbreak on a geriatric ward.

背景在 SARS-CoV-2 大流行期间,优势病毒变异株一再被特性发生改变的新变异株所取代,从而经常改变感染事件的动态以及疫苗和疗法的有效性。德国美因茨大学医学中心通过全基因组测序对 SARS-CoV-2 变体进行监测,以支持大流行期间的患者管理。获得的基因组序列与公共数据库中的序列进行比对,以进行变异分配。为了进行分类,我们构建了系统发生树,以绘制临床环境中的变异体分布图和当时的疫情。我们以一个老年病房为例介绍了监测程序。因此,可以精确地观察到 SARS-CoV-2 的阿尔法变种到德尔塔变种和奥米克龙变种的变化。此外,还可追踪到近来 Omicron 亚变种的快速变化。通过阐明循环菌株之间的系统发育关系,可以得出有关传播途径的结论。通过一个老年病房的例子,我们展示了全基因组测序的变异监测如何支持病房的感染预防和控制程序,并为控制疫情爆发做出贡献。事实证明,该计划有助于控制老年病房的疫情爆发。

Digital epidemiology is the process of investigating the dynamics of disease-related patterns, both social and clinical, as well as the causes of these trends in epidemiology. Digital epidemiology, utilising big data from a variety of digital sources, has emerged as a viable method for early detection and monitoring of viral outbreaks. The present review gives an overview of digital epidemiology, emphasising its importance in the timely detection of infectious disease outbreaks. Researchers may discover and track outbreaks in real time using digital data sources such as search engine queries, social media trends, and digital health records. However, data quality, concerns about privacy, and data interoperability must be addressed to maximise the effectiveness of digital epidemiology. As the global landscape of infectious diseases evolves, integrating digital epidemiology becomes critical to improving pandemic preparedness and response efforts. Integrating digital epidemiology into routine monitoring systems has the potential to improve global health outcomes and save lives in the event of viral outbreaks.

数字流行病学是调查与疾病相关的社会和临床模式的动态以及这些流行病学趋势的原因的过程。数字流行病学利用各种数字来源的大数据,已成为早期发现和监测病毒爆发的可行方法。本综述概述了数字流行病学,强调其在及时发现传染病爆发方面的重要性。研究人员可利用搜索引擎查询、社交媒体趋势和数字健康记录等数字数据源实时发现和跟踪疫情。然而,要最大限度地发挥数字流行病学的功效,必须解决数据质量、隐私问题和数据互操作性等问题。随着全球传染病态势的演变,整合数字流行病学对于改进大流行病防备和应对工作至关重要。将数字流行病学纳入常规监测系统有可能在病毒爆发时改善全球健康状况并挽救生命。

Background

Meropenem (MEPM) holds significance in treating severe infections and drug-resistant bacteria. There are concerns that antimicrobial shortages may lead to the use of alternative antimicrobials that are less effective and safer. We have responded to the MEPM shortage with post-prescription monitoring and feedback (PPRF) with no restrictions on MEPM initiation. We aimed to assess the impact of the MEPM shortage and the PPRF on broad-spectrum antimicrobial use and mortality.

Methods

This retrospective study was conducted in a single hospital in Japan. The period from October 2021 to August 2022 was defined as the period before the MEPM shortage, and the period from September 2022 to March 2023 was defined as the period during the MEPM shortage. To support the appropriate use of antimicrobials during MEPM shortages, the antimicrobial stewardship team (AST) developed a list of alternatives to MEPM. An interrupted time series analysis was used to assess changes in use and mortality among patients receiving broad-spectrum antimicrobials over the study period.

Discussion

The shortage of MEPM and PPRF temporarily increased the use of alternative cefepime; however, the subsequent change in days of therapy and days of coverage of broad-spectrum antimicrobials suggests a decrease in the use of these antimicrobials. Despite these shifts, the mortality rates remained stable, suggesting that the response to the shortage did not adversely affect treatment outcomes.

Conclusion

In the context of antimicrobial shortages, AST support plays an important role in enabling physicians to make optimal use of antimicrobials.

背景美罗培南(MEPM)在治疗严重感染和耐药细菌方面具有重要意义。有人担心,抗菌药物短缺可能会导致人们使用疗效更差、安全性更低的替代抗菌药物。为应对 MEPM 短缺,我们采取了处方后监测和反馈(PPRF)措施,对 MEPM 的使用不加限制。我们旨在评估 MEPM 短缺和 PPRF 对广谱抗菌药物使用和死亡率的影响。2021 年 10 月至 2022 年 8 月期间被定义为 MEPM 短缺之前,2022 年 9 月至 2023 年 3 月期间被定义为 MEPM 短缺期间。为支持在 MEPM 短缺期间合理使用抗菌药物,抗菌药物管理小组 (AST) 制定了一份 MEPM 替代品清单。讨论MEPM和PPRF的短缺暂时增加了头孢吡肟替代品的使用;然而,随后治疗天数和广谱抗菌药物覆盖天数的变化表明这些抗菌药物的使用有所减少。尽管出现了这些变化,但死亡率仍保持稳定,这表明应对抗菌药物短缺的措施并未对治疗效果产生不利影响。

Background

Despite the widely reported success of knee arthroplasty, studies show that 1.6–3 % of patients undergo revision within the first postoperative year predominantly due to infection. Preoperative skin preparation may potentially decrease the bacterial load and consequently, the risk of periprosthetic joint infections. The effects of hair removal on prosthetic joint infection are inconsistent. Our primary aim was to investigate if hair removal with a clipper influenced skin colonisation and bacterial composition.

Methods

Forty Caucasian male participants who were planned to undergo knee arthroplasty, (mean age 63.8 years), were included. Patients were randomised to hair removal in a within-person study design. As a control, the opposite leg of the patient was used. Swabs were collected prior to hair removal (baseline), immediately after hair removal (Day 0), and with follow-up after one and seven days.

Results

The intervention showed significant decrease in mean log colony-forming units per. cm2 from baseline 2.97 to 2.67 (P<0.01) immediately after hair removal and sustained at Day 1 (P=0.01). At Day 7, the mean was non-significant compared to baseline. The control group did not show any decrease of skin microbiota at follow-up on Day 0, 1 or 7.

No significant differences within the bacterial composition were found between the intervention and control leg at baseline among the six most prevalent detected bacterial species: Staphylococcus epidermidis, Micrococcus luteus, S. hominis, S. capitis, S. haemolyticus and S. aureus. The study did not find any changes in the bacterial composition over time.

Conclusion

Hair removal with a clipper within 24 hours prior to surgery causes a significant non-selective reduction in skin colonisation.

背景尽管膝关节置换术的成功已被广泛报道,但研究表明,1.6%-3%的患者在术后第一年内主要因感染而进行翻修。术前皮肤准备可能会减少细菌负荷,从而降低假体周围关节感染的风险。脱毛对假体关节感染的影响并不一致。我们的主要目的是研究用剪子脱毛是否会影响皮肤定植和细菌组成。方法纳入 40 名计划接受膝关节置换术的白种男性患者(平均年龄 63.8 岁)。在人内研究设计中,患者被随机安排脱毛。对照组使用患者的对侧腿部。脱毛前(基线)、脱毛后(第 0 天)立即收集拭子,并在 1 天和 7 天后进行随访。结果干预显示,脱毛后,每平方厘米平均菌落形成对数单位从基线 2.97 显著降至 2.67(P<0.01),并在第 1 天持续下降(P=0.01)。在第 7 天,平均值与基线相比没有显著变化。在第 0 天、第 1 天或第 7 天的随访中,对照组的皮肤微生物群没有出现任何减少。在基线时,干预组和对照组腿部的细菌组成在检测到的六种最常见细菌中没有发现明显差异:表皮葡萄球菌、黄体小球菌、人葡萄球菌、头癣葡萄球菌、溶血性葡萄球菌和金黄色葡萄球菌。结论:在手术前 24 小时内用剪子拔除头发会导致皮肤定植的非选择性显著减少。

Background

While most infection prevention and control (IPC) studies focus on healthcare professionals, IPC is everyone's responsibility in any healthcare facility. There is little known about the IPC knowledge among the cleaners who are responsible for housekeeping, environmental cleaning, and waste management within hospitals. This study sought to evaluate the knowledge and practice of IPC among cleaners at Mulago National Referral Hospital (MNRH) to establish a foundation for empowering a strategic workforce that will improve IPC practices within the hospital.

Methods

A cross-sectional study was conducted among the cleaners in a national referral hospital in Uganda. The participants were purposively sampled, and data was collected using a web-based, interviewer-administered, questionnaire about IPC knowledge and practices.

Results

Of the 120 cleaners recruited, 52.5% were female. Good IPC knowledge was demonstrated in 58.3%, and 30.8% reported good IPC practices. Participants with at least 5 years' work experience had higher knowledge levels (aOR: 10.3, P=0.006, 95% CI: 2–54). Those closely supervised had lower IPC knowledge compared with those with less supervision. Participants with fixed work schedules (aOR: 0.2, P=0.028, 95%CI: 0–0.8), were less likely to exhibit good IPC practices. In addition, 63.1% were knowledgeable about waste segregation, recognising bin colours and the correct disposal of sharps and needles. Despite good compliance with personal protective equipment, poor hand-washing practices were reported. A positive correlation between knowledge and practice scores was established.

Conclusion

Hospital cleaners in a national referral hospital in Uganda IPC reported poor infection prevention practices despite good knowledge. For IPC knowledge and practice to correlate positively, ongoing practical training is vital to maintain knowledge and good practice to establish a successful IPC program.

背景虽然大多数感染预防和控制(IPC)研究都集中在医护人员身上,但在任何医疗机构中,IPC 都是每个人的责任。人们对医院中负责内务、环境清洁和废物管理的清洁工的 IPC 知识知之甚少。本研究旨在评估穆拉戈国家转诊医院(Mulago National Referral Hospital,MNRH)清洁工的 IPC 知识和实践情况,为培养一支具有战略眼光的员工队伍奠定基础,从而改善医院内的 IPC 实践。对参与者进行了有目的的抽样调查,并使用基于网络、由访谈者主持的有关 IPC 知识和实践的问卷收集数据。结果 在招募的 120 名清洁工中,52.5% 为女性。58.3%的人具有良好的 IPC 知识,30.8%的人报告了良好的 IPC 实践。拥有至少 5 年工作经验的参与者具有更高的知识水平(aOR:10.3,P=0.006,95% CI:2-54)。与监督较少的人相比,受到密切监督的人对 IPC 的了解程度较低。工作时间固定的参与者(aOR:0.2,P=0.028,95%CI:0-0.8)更不可能表现出良好的 IPC 实践。此外,63.1%的受试者了解废物分类、识别垃圾桶颜色以及正确处理利器和针头。尽管对个人防护设备的遵守情况良好,但洗手的习惯却很差。结论 乌干达一家国家转诊医院的医院清洁工尽管对 IPC 有较好的了解,但报告的感染预防实践较差。要使 IPC 知识与实践呈正相关,持续的实践培训对于保持知识和良好实践以建立成功的 IPC 计划至关重要。

Members of the genus Phytobacter (order Enterobacterales) are isolated from the natural environment and clinical settings. Identification of Phytobacter strains based on biochemical characteristics is complicated due to taxonomic confusion, and they are often misidentified by automated identification systems in laboratories.

In this study we describe the first three clinical cases associated with Phytobacter spp. reported in Argentina. We describe the identification, the molecular analysis using whole genome sequencing and the potential clinical relevance.

植物细菌属(肠杆菌目)的成员是从自然环境和临床环境中分离出来的。由于分类混乱,根据生化特征鉴定植物杆菌菌株非常复杂,而且实验室的自动识别系统经常对它们进行错误鉴定。本研究描述了阿根廷首次报告的三例与植物细菌属有关的临床病例,介绍了鉴定方法、使用全基因组测序进行的分子分析以及潜在的临床意义。

An outbreak of Pseudomonas aeruginosa urinary tract infections following cystoscopy traceable to a malfunctioning drying cabinet 膀胱镜检查后爆发铜绿假单胞菌尿路感染,可追溯到干燥柜故障

Background

Pseudomonas aeruginosa is an important bacterial pathogen, particularly as a cause of nosocomial infections in hospitalized patients. Only few reports exist in which cystoscopes were implicated as an outbreak source. We describe an investigation into the cause of a sudden increase in the number of urinary tract infections (UTI) with P. aeruginosa in patients after cystoscopy. In addition, we share the lessons learned and measures taken to reduce the risk of similar infections in the future.

Presentation of Case

Over a period of two weeks the urology outpatient department noticed a UTI in four patients following cystoscopy. An investigation was started for a common source of the outbreak in the urological treatment room. Additional screening of patients revealed a total of eleven males with P. aeruginosa UTI following cystoscopy. The infections were found to be due to a defective drying cabinet, which lacked an alarm signaling in case of loss of airflow. Amplified fragment length polymorphism (AFLP) analysis revealed that P. aeruginosa isolates from three patients and six isolates from environmental cultures (including cystoscopes from the drying cabinet) genotypically belonged to one strain.

Discussion

The AFLP results suggest that contaminated cystoscopes caused P. aeruginosa UTI in 11 patients, with the drying cabinet as site of transfer of the infective strain. To our knowledge, this is the first report describing a malfunctioning drying cabinet as source of an outbreak following cystoscopy.

Conclusion

In case of concomitant P. aeruginosa infections, cystoscopes and drying cabinets should be suspected as a potential source. Molecular techniques are helpful in investigating the epidemiology of an outbreak.

背景铜绿假单胞菌是一种重要的细菌病原体,尤其是造成住院病人院内感染的病原体。目前只有极少数报道称膀胱镜是疫情爆发源。我们介绍了对膀胱镜检查后患者尿路感染(UTI)铜绿假单胞菌数量突然增加的原因进行的调查。此外,我们还分享了汲取的教训和采取的措施,以降低今后发生类似感染的风险。病例介绍泌尿科门诊部在两周内发现四名患者在接受膀胱镜检查后发生了尿路感染。于是开始调查泌尿科治疗室是否存在疫情爆发的共同源头。对患者进行的额外筛查显示,共有 11 名男性患者在接受膀胱镜检查后感染了铜绿假单胞菌性尿道炎。发现这些感染是由于干燥柜存在缺陷,在气流消失时没有发出警报信号所致。扩增片段长度多态性(AFLP)分析表明,从三名患者分离的铜绿假单胞菌和从环境培养物(包括干燥柜中的膀胱镜)中分离的六名铜绿假单胞菌在基因型上属于同一菌株。讨论 AFLP结果表明,受污染的膀胱镜导致了11名患者的铜绿假单胞菌UTI,而干燥柜是感染菌株的转移场所。据我们所知,这是首例描述干燥柜故障是膀胱镜检查后疫情爆发源头的报告。分子技术有助于调查疫情的流行病学。
