Background: Health care workers (HCW) in Emergency Medical Services (EMS) frequently come into contact with carriers of methicillin-susceptible Staphylococcus aureus (MSSA) and methicillin-resistant Staphylococcus aureus (MRSA) strains and may acquire and transmit them to patients. However, there is little data on MSSA and MRSA colonization of medical personnel in the emergency services. Additionally, few studies have analyzed the association between personal hygiene of staff and colonization. Therefore, we examined the prevalence of MSSA and MRSA in EMS staff of two German regions and evaluated their personal hygiene behavior.

Method: Throat and nasal swabs from 300 EMS workers were analyzed. Both direct and pre-enriched cultures of the swabs were cultivated on culture media to identify MSSA and MRSA. Results were analyzed together with questionnaires about sociodemographic data and a self-assessment of hygiene behavior. Statistical analysis was done using the R statistical software.

Results: Of the total 300 swabs, 55% were from paramedics, 39% were from emergency medical technicians (EMT) and 5% were from emergency physicians. With 1%, the MRSA prevalence was comparable to that of the German population, while the MSSA rate - 43.7% - was higher than expected. Colonization with MSSA was significantly associated with poor hand hygiene and male sex, and was inversely correlated to time on the job in EMS.

Conclusion: The sample size of 300 and a MRSA prevalence of 1% made a meaningful analysis of potential influencing factors on the prevalence of MRSA infeasible. The comparatively high prevalence of MSSA and the association with decreasing frequency of hand antisepsis suggests an influence of personal hygiene on MSSA colonization. HCW in EMS should be encouraged to make use of their personal protective equipment and practice frequent hand hygiene. The implementation of diagnostic tools such as the Hand Hygiene Self-Assessment Framework of the WHO could be utilized to reveal problems in organizations, followed by an individual program to promote hand hygiene.

背景:紧急医疗服务(EMS)中的医护人员(HCW)经常接触甲氧西林易感金黄色葡萄球菌(MSSA)和耐甲氧西林金黄色葡萄球菌(MRSA)菌株的携带者,并可能将其传染给病人。然而,有关急诊服务中医务人员 MSSA 和 MRSA 定植情况的数据却很少。此外,很少有研究分析工作人员的个人卫生与定植之间的关系。因此,我们研究了德国两个地区急救人员的 MSSA 和 MRSA 感染率,并评估了他们的个人卫生行为:方法:分析了 300 名急救人员的喉拭子和鼻拭子。方法:对 300 名急救人员的咽拭子和鼻拭子进行分析,在培养基上对咽拭子进行直接培养和预富集培养,以鉴定 MSSA 和 MRSA。分析结果与有关社会人口学数据和卫生行为自我评估的问卷一起进行。统计分析使用 R 统计软件进行:在总共 300 份棉签中,55% 来自医护人员,39% 来自急救医疗技术人员(EMT),5% 来自急诊医生。MRSA感染率为1%,与德国人口的感染率相当,而MSSA感染率(43.7%)则高于预期。MSSA定植与手部卫生差和男性性别有明显关系,与在急救中心工作的时间成反比:300个样本和1%的MRSA感染率使得对MRSA感染率的潜在影响因素进行有意义的分析变得不可能。相对较高的 MSSA 感染率以及与手部消毒频率下降的关联表明,个人卫生对 MSSA 定植有影响。应鼓励急救服务中的医护人员使用个人防护设备并经常进行手部卫生。可利用诊断工具(如世界卫生组织的 "手部卫生自我评估框架")来揭示组织中存在的问题,然后制定个人计划来促进手部卫生。

The aim of this study was to assess whether toothbrushing with a dentifrice containing an antimicrobial phthalocyanine derivative (APD) can reduce the intraoral viral load of SARS-CoV-2. Twenty COVID-19-positive dentate patients aged ≥18 years were selected instructed to brush their teeth for 2 min with a dentifrice containing APD. Self-collected samples of unstimulated saliva were carried out three times: T0 (baseline), T5 (5 min after toothbrushing), and T30 (30 min after toothbrushing). The analysis of viral RNA was performed by RT-qPCR for detection of three viral genes (ORF1ab, N and S genes). Results were statistically tested using Friedman's test and pairwise comparison with Bonferroni corrections, with a significance level of 5%. There was an increase in the cycle threshold (Ct) value from T0 to T5 in 13 patients (72.2%), and from T0 to T30 in 14 patients (77.8%). In two patients (11.1%) no SARS-CoV-2 was detected at T5 and five patients (27.8%) at T30. The Ct values were statistically significantly higher (p=0.020) at T30 in comparison to T0 and T5. This pilot study suggests that toothbrushing with a dentifrice containing APD could reduce the SARS-CoV-2 viral load in the oral cavity. However, further studies are needed to confirm this possible beneficial effect against SARS-CoV-2.

本研究的目的是评估使用含有抗菌酞菁衍生物(APD)的牙膏刷牙是否能减少 SARS-CoV-2 的口腔内病毒载量。选取了 20 名 COVID-19 阳性、年龄≥18 岁的无牙患者,指导他们使用含 APD 的牙膏刷牙 2 分钟。对未受刺激的唾液样本进行三次自我采集:T0(基线)、T5(刷牙后 5 分钟)和 T30(刷牙后 30 分钟)。病毒 RNA 分析采用 RT-qPCR 方法,检测三个病毒基因(ORF1ab、N 和 S 基因)。结果采用弗里德曼检验和配对比较进行统计检验,并进行 Bonferroni 校正,显著性水平为 5%。13名患者(72.2%)的周期阈值(Ct)从T0升至T5,14名患者(77.8%)的周期阈值(Ct)从T0升至T30。有 2 名患者(11.1%)在 T5 检测不到 SARS-CoV-2,有 5 名患者(27.8%)在 T30 检测不到 SARS-CoV-2。与 T0 和 T5 相比,T30 的 Ct 值在统计学上明显更高(p=0.020)。这项试验研究表明,使用含 APD 的牙膏刷牙可减少口腔中的 SARS-CoV-2 病毒载量。然而,还需要进一步的研究来证实这种可能对 SARS-CoV-2 有益的效果。

Background: For reusable devices and device components, effective reprocessing is essential to prevent nosocomial infections.

Aim: The objective of the study was to evaluate manual cleaning as the first step of reprocessing reusable glass probes of a device for generation of non-invasive physical plasma, in accordance with regulations.

Methods: Two glass probes of the device were contaminated with human blood. For manual cleaning, both probes were cleaned with instrument cleaning agent and instrument brushes. Cleaning efficacy was evaluated by total protein measurement in the rinsing solution.

Results: After manual cleaning of the two test glass probes, no protein from the test contamination with human blood could be detected. Neither the different design of the two probes nor the use of a hard or a soft instrument brush demonstrated any difference.

Conclusion: Our data suggest that manual cleaning of glass probes achieves complete removal of organic contaminants. This should enable safe applications in clinical practice.

Background: Hydatid cysts (HC) are zoonotic diseases that are mainly caused by Echinococcus granulosus. Ovarian HC is a rare condition with different and unspecified presentations. Here we report a rare case of primary ovarian HC.

Case presentation: A 47-year-old woman with chronic abdominal pain and left hemipelvic fullness was referred to the Obstetrics Clinic of the Kowsar Hospital of Qazvin. Abdominopelvic sonography revealed a cystic mass, which primarily suggested a cyst adenoma. The tumor marker levels were within normal limits. After surgical resection, histopathological examination showed a cystic mass with dimensions of 10×6×3 cm, smooth external and internal aspects, wall thickness of 0.3 cm, and multiple pieces of irregular gray membranous tissue. The patient was treated with albendazole 3 months after surgery, and a 6-month follow-up sonogram revealed no signs of recurrence.

Discussion: HC has non-specific presentations. Radiologists, pathologists, and surgeons should consider HC as a differential diagnosis for any cystic mass in the pelvic cavity, especially in endemic areas. Surgical resection and albendazole administration are the chosen treatments.

背景:包虫囊肿(HC)是一种人畜共患病,主要由棘球蚴引起。卵巢水包虫囊肿是一种罕见的疾病,其表现各异且不明确。在此,我们报告了一例罕见的原发性卵巢囊肿病例:一名 47 岁女性因长期腹痛和左侧骨盆饱满被转诊至加兹温 Kowsar 医院产科诊所。腹盆腔超声检查发现一个囊性肿块,主要提示为囊腺瘤。肿瘤标志物水平在正常范围内。手术切除后,组织病理学检查显示,囊性肿块大小为 10×6×3 厘米,内外光滑,壁厚 0.3 厘米,有多块不规则的灰色膜组织。术后 3 个月,患者接受了阿苯达唑治疗,6 个月的随访声像图显示无复发迹象:讨论:HC 具有非特异性表现。放射科医生、病理科医生和外科医生应将 HC 作为盆腔囊性肿块的鉴别诊断,尤其是在地方病流行地区。可选择手术切除和阿苯达唑治疗。

Background: Healthcare-associated infections cause high mortality and morbidity, and lack of stethoscope disinfection is one of the reasons for healthcare-associated infections. Nurses who frequently use stethoscopes in the clinic do not disinfect stethoscopes at high rates. This study aimed to identify the frequency of stethoscope disinfection by nurses and their knowledge about the same.

Methods: This was a mixed-methods observational study. The quantitative part of the study included 202 nurses, the qualitative part included 12. Two researchers who made observations during stethoscope use recorded the procedures the nurses performed on the "Observation Form". Semi-structured in-depth interviews were conducted based on phenomenological methods.

Results: 23.7% of the nurses disinfected their stethoscopes before contact with patients, 11.8% after contact with patients and 6.4% before and after contact with patients. The nurses used a stethoscope on an average of 7.42 patients without disinfecting it. In the qualitative interview, some nurses stated that they did not have information about the disinfectants to be used for stethoscopes and their effectiveness. Some of the participants in the present study stated that they did not receive training on stethoscope disinfection and that they did not know that there were guidelines about it.

Conclusion: Since there were deficiencies in the implementation of stethoscope disinfection as well as knowledge, the transfer of knowledge in this context must receive more attention in education and training.

背景:医护人员相关感染会导致很高的死亡率和发病率,而听诊器消毒不到位是医护人员相关感染的原因之一。临床上经常使用听诊器的护士对听诊器的消毒率不高。本研究旨在了解护士对听诊器进行消毒的频率及其相关知识:这是一项混合方法观察研究。研究的定量部分包括 202 名护士,定性部分包括 12 名护士。两名研究人员在听诊器使用过程中进行观察,并在 "观察表 "上记录护士执行的程序。研究结果显示:23.7% 的护士在接触患者前对听诊器进行了消毒,11.8% 的护士在接触患者后对听诊器进行了消毒,6.4% 的护士在接触患者前后对听诊器进行了消毒。护士平均对 7.42 名患者使用听诊器时未进行消毒。在定性访谈中,一些护士表示她们不了解听诊器使用的消毒剂及其效果。本研究的一些参与者表示,他们没有接受过听诊器消毒方面的培训,也不知道有相关的指导原则:由于在听诊器消毒的实施和知识方面存在不足,因此在教育和培训中必须更加重视这方面的知识传授。

Background: Antituberculosis drugs may cause mild, moderate or severe adverse drug reactions (ADR) leading to poor compliance. Description of the pattern of ADR and their related factors can help tuberculosis (TB) control program as part of the WHO programs. This study aims to investigate the incidence of ADR and associated factors among TB patients in northern Iran.

Methods: This is a retrospective cohort study. The required information, including year of diagnosis, age, gender, residence area, nationality, HIV co-morbidity, history of anti TB treatment and ADR, was obtained from the Deputy of Health, Mazandaran University of Medical Sciences, Iran. All data were analyzed using SPSS version 21 software.

Results: Out of 3903 TB patients, 136 (3.5%) experienced major ADR. The incidence of ADR for men and women as well as for those with and without previous treatment history were 3.9% vs. 3.3% and 5.3% vs. 3.4%, respectively (p>0.05). Multiple logistic regression models showed a higher chance of ADR among those aged over 59 compared with those aged under 29 (OR=2.63, 95% confidence interval: 1.54-4.49).

Conclusions: Age over 59 can be considered a risk factor for ADR with anti-TB drug administration.

背景:抗结核药物可能会引起轻度、中度或严重的药物不良反应(ADR),从而导致用药依从性差。作为世界卫生组织计划的一部分,描述药物不良反应的模式及其相关因素有助于结核病(TB)控制计划。本研究旨在调查伊朗北部肺结核患者的药物不良反应发生率及其相关因素:这是一项回顾性队列研究。所需信息,包括诊断年份、年龄、性别、居住地区、国籍、HIV 并发症、抗结核治疗史和 ADR,均从伊朗马赞达兰医科大学卫生副校长处获得。所有数据均使用 SPSS 21 版软件进行分析:在 3903 名肺结核患者中,136 人(3.5%)出现了严重的 ADR。男性和女性以及有和无既往治疗史患者的 ADR 发生率分别为 3.9% vs. 3.3% 和 5.3% vs. 3.4% (P>0.05)。多元逻辑回归模型显示,59岁以上人群发生ADR的几率高于29岁以下人群(OR=2.63,95%置信区间:1.54-4.49):结论:59 岁以上可被视为服用抗结核药物发生 ADR 的风险因素。

Aim: The purpose of this study is to undertake an integrative literature review in order to determine the prevalence, etiology, and reactivation of oral HSV infection in patients receiving chemotherapy (CT).

Methods: The study was carried out in the PubMed/MEDLINE, Embase, Virtual Health Library, and Scopus databases, using the descriptors "Herpes Simplex", "Viral Diseases", "Mouth", and "Antineoplastic Agents".

Results: The findings suggest that HSV infection is widespread in this group of patients and can be severe. HSV infection is frequent in CT patients, and treatment should begin as soon as it is feasible, utilizing antivirals to avoid future difficulties, as patients are immunocompromised.

Conclusion: It is critical for health professionals to be fully informed on the dangers and treatment choices available, with the most appropriate therapy for each circumstance. Furthermore, more recent research with acceptable methodological rigor is required to better quantify the prevalence of HSV in these patients.

目的:本研究旨在进行综合文献综述,以确定接受化疗(CT)的患者口腔 HSV 感染的流行率、病因和再激活情况:研究在 PubMed/MEDLINE、Embase、Virtual Health Library 和 Scopus 数据库中进行,使用的描述符为 "单纯疱疹"、"病毒性疾病"、"口腔 "和 "抗肿瘤药物":结果:研究结果表明,HSV 感染在这类患者中很普遍,而且可能很严重。由于患者免疫力低下,CT 患者中常有 HSV 感染,因此应尽快开始治疗,并使用抗病毒药物,以避免日后出现困难:医护人员必须充分了解疾病的危害和治疗方法,并根据具体情况选择最合适的疗法。此外,为了更好地量化 HSV 在这些患者中的流行情况,还需要更多方法严谨的最新研究。

Background: Special antibiotics are prescribed against Helicobacter (H.) pylori. However, sometimes the bacteria are not completely eliminated, or they are recurrent. Unlike most infections, it is very difficult to eliminate a H. pylori infection. Heteroresistance is defined as the phenomenon in which subpopulations of the same colony of bacteria exhibit a range of susceptibilities to a particular antibiotic. Because of heteroresistant cells, antibiotic failure and chronic infection can occur; thus, the current research aimed to investigate presence of heteroresistant cells in H. pylori collected from patients reffering to clinic in Ilam, Iran. Subsequently, patients who were infected with heteroresistant H. p ylori were treated with antibiotics effective against heteroresistant subpopulations.

Methods: In this cross-sectional descriptive study, 100 patients with clinical symptoms and suspected of being infected with H. pylori were studied in private clinics in Ilam, Iran. Fiftyisolates of H. pylori accompanied by patients' information were obtained from Ilam clinics. We cultured the bacteria to identify heteroresistance and to find the cause of recurrent infection in these patients.

Results: Out of a total of 50 samples, 3 were heteroresistant to clarithromycin (6%). Levofloxacin was applied in cases of heteroresistant samples, and the effectiveness was determined after one month of follow-up of patients.

Conclusion: Patients with heteroresistance showed sensitivity to levofloxacin. After one month of follow-up, it was found that the effectiveness of this antibiotic was good. Therefore, this antibiotic was introduced as a more effective drug in patients with heteroresistant H. pylori.

背景:针对幽门螺旋杆菌(H.Pylori)的处方是特殊抗生素。但是,有时幽门螺杆菌并不能被完全清除,或者会反复发作。与大多数感染不同,幽门螺杆菌感染很难根除。异抗性是指同一菌群的亚群对某种抗生素表现出不同的敏感性。由于异抗细胞的存在,抗生素可能失效并导致慢性感染;因此,目前的研究旨在调查从伊朗伊拉姆诊所采集的幽门螺杆菌患者体内是否存在异抗细胞。随后,感染了异抗性幽门螺杆菌的患者接受了对异抗性亚群有效的抗生素治疗:在这项横断面描述性研究中,伊朗伊拉姆私人诊所对 100 名有临床症状并怀疑感染幽门螺杆菌的患者进行了研究。我们从伊拉姆诊所获得了幽门螺杆菌的50个分离样本以及患者信息。我们对细菌进行了培养,以确定异抗性,并找出这些患者反复感染的原因:在总共 50 份样本中,有 3 份对克拉霉素产生了异抗性(6%)。结果:在总共 50 个样本中,有 3 个样本对克拉霉素产生了异耐药性(6%),对产生异耐药性的样本使用了左氧氟沙星,并在对患者进行一个月的随访后确定了疗效:结论:异抗性患者对左氧氟沙星敏感。经过一个月的随访发现,该抗生素的疗效良好。因此,在对幽门螺杆菌产生异抗性的患者中,该抗生素是一种更有效的药物。

Aim: To recognize and analyze the 100 most-cited articles on post-operative infections following cardiothoracic surgery and vascular procedures in the past 20 years.

Methods: Articles published on post-operative infections following cardiothoracic surgery and vascular procedures from inception 1986 till 2020 were reviewed and selected by two authors, based on their number of citations using the Scopus database. Their characteristics were recorded, i.e., title, authors, publication date, total no. of citations, citations per year (CPY), country of research, institutional affiliation, journal, research subject, and article type.

Results: The top 100 most influential articles were published between 1968 and 2017, with the peak in 2002. The mean number of total citations was 236.79 (range: 108-1,157). Areas with a medical focus were predominant in the studied research articles on the researched topic. The top-most journals in which these articles were published include Annals of Thoracic Surgery (14), followed by Circulation (8), and the New England Journal of Medicine (8). The number of publications affiliated with an institution were highest in the United States, with the Cleveland Clinic Foundation (6) having the most.

Conclusion: These findings highlight that there is a great potential to conduct research and publish the prevalence, causes, risk factors, pathogenesis and molecular biology of post-cardiac and -vascular surgery infections to prevent their adverse effects. The results can be taken into consideration for policy making to improve post-cardiac-surgery outcomes.

目的:识别并分析过去20年中被引用次数最多的100篇关于心胸手术和血管手术术后感染的文章:两位作者使用 Scopus 数据库对 1986 年至 2020 年间发表的有关心胸手术和血管手术术后感染的文章进行了审查,并根据其被引用次数进行了筛选。记录了这些文章的特征,即标题、作者、发表日期、总引用次数、年引用次数(CPY)、研究国家、所属机构、期刊、研究主题和文章类型:最具影响力的前 100 篇文章发表于 1968 年至 2017 年之间,其中 2002 年为高峰期。总引用次数的平均值为 236.79 次(范围:108-1,157 次)。在研究主题的研究文章中,以医学领域为主。这些文章发表最多的期刊包括《胸外科年鉴》(14 篇)、《循环》(8 篇)和《新英格兰医学杂志》(8 篇)。在美国,隶属于某个机构的论文数量最多,其中克利夫兰诊所基金会(6 篇)最多:这些研究结果突出表明,对心脏和血管手术后感染的发病率、原因、风险因素、发病机制和分子生物学进行研究和发表论文,以预防其不良影响的潜力巨大。在制定政策时可以考虑这些结果,以改善心脏手术后的治疗效果。

Background: The high prevalence of virulence-associated genes observed in Acinetobacter baumannii isolates underscores the pathogenic potential of this bacterium. The presence of these genes confers enhanced survival, evasion of host defenses, and increased virulence. In this study, we investigate the presence and distribution of genes associated with virulence and assess the antimicrobial susceptibility patterns in clinical isolates of A. baumannii.

Materials and method: This research focused on examining the 50 multi-drugs resistant (MDR) strains that were included in this investigation. The identification of these strains was validated using Oxa-51. The presence of the BauA and BasD genes was determined through conventional PCR techniques.

Results: The results derived from Oxa-51 PCR confirmed the identification of all 50 selected strains of A. baumannii. Additionally, both the BauA and BasD genes were successfully identified in 82% of the MDR strains.

Conclusion: Moreover, the varying antibiotic resistance patterns highlight the challenge in treating A. baumannii infections effectively. Strategies such as combination therapy, antimicrobial stewardship, and infection control measures should be considered to combat this multidrug-resistant pathogen.

背景:在鲍曼不动杆菌分离株中观察到的毒力相关基因的高流行率凸显了这种细菌的致病潜力。这些基因的存在提高了鲍曼不动杆菌的存活率,逃避了宿主的防御,并增强了毒力。在本研究中,我们调查了鲍曼不动杆菌临床分离株中与毒力相关的基因的存在和分布情况,并评估了其抗菌药敏感性模式:本研究的重点是检测 50 株具有多重耐药性(MDR)的菌株。使用 Oxa-51 对这些菌株进行了鉴定。通过传统的 PCR 技术确定了 BauA 和 BasD 基因的存在:结果:通过 Oxa-51 PCR 得出的结果证实了所有 50 株选定鲍曼不动杆菌菌株的鉴定结果。此外,在 82% 的 MDR 菌株中成功鉴定出了 BauA 和 BasD 基因:此外,不同的抗生素耐药性模式凸显了有效治疗鲍曼不动杆菌感染所面临的挑战。此外,不同的抗生素耐药模式也凸显了有效治疗鲍曼不动杆菌感染所面临的挑战,应考虑采用联合疗法、抗菌药物管理和感染控制措施等策略来对抗这种多重耐药病原体。
