Abstract

Chemical disinfection is an indispensable means of preventing infection. This holds true for healthcare settings, but also for all other settings where transmission of pathogens poses a potential health risk to humans and/or animals. Research on how to ensure effectiveness of disinfectants and the process of disinfection, as well as on when, how and where to implement disinfection precautions is an ongoing challenge requiring an interdisciplinary team effort. The valuable resources of active substances used for disinfection must be used wisely and their interaction with the target organisms and the environment should be evaluated and monitored closely, if we are to reliable reap the benefits of disinfection in future generations. In view of the global threat of communicable diseases and emerging and re-emerging pathogens and multidrug-resistant pathogens, the relevance of chemical disinfection is continually increasing. Although this consensus paper pinpoints crucial aspects for strategies of chemical disinfection in terms of the properties of disinfectant agents and disinfection practices in a particularly vulnerable group and setting, i.e., patients in healthcare settings, it takes a comprehensive, holistic approach to do justice to the complexity of the topic of disinfection.

Abstract

In the past years infections caused by multidrug-resistant Gram-negative bacteria have dramatically increased in all parts of the world. This consensus paper is based on presentations, subsequent discussions and an appraisal of current literature by a panel of international experts invited by the Rudolf Schülke Stiftung, Hamburg. It deals with the epidemiology and the inherent properties of Gram-negative bacteria, elucidating the patterns of the spread of antibiotic resistance, highlighting reservoirs as well as transmission pathways and risk factors for infection, mortality, treatment and prevention options as well as the consequences of their prevalence in livestock. Following a global, One Health approach and based on the evaluation of the existing knowledge about these pathogens, this paper gives recommendations for prevention and infection control measures as well as proposals for various target groups to tackle the threats posed by Gram-negative bacteria and prevent the spread and emergence of new antibiotic resistances.

Abstract

Purpose: The Fourth Industrial Revolution (4IR) holds the potential to significantly improve capabilities and performances for architectural, engineering, construction and operation and maintenance (AECO) companies in India. The top management of such companies seems unsure and reluctant to implementation of the 4IR applications. The objective of this research is to identify the 4IR technology applications, which would have a significant impact on the operation of the AECO companies in India. Moreover, the paper further attempts to give a conceptual roadmap for the implementation of these 4IR technologies in the AECO value chain. Design/methodology/approach: The nascent level of research in 4IR in construction necessitated the adoption of mixed methodologies in research. Hypothesis testing has been carried out on the quantitative data to ascertain the potential of 4IR technologies, which could significantly impact the AECO companies. Subsequently, qualitative research has been used to explore the reasons impacting the technology adoption and generate a possible road map for the implementation of the significant 4IR technology applications. Findings: The AECO value chain is challenged due to its complexity, uncertainty, fragmented supply chains, myopic thinking and a culture reluctant to change. The study provides insights into the dilemmas of practitioners in the Indian context while exploring possible approaches to carry out the transformation in AECO. Research limitations/implications: The study validation relied on the opinions, perspectives and recollections of respondents. The opinion of practicing professionals was limited to the Indian context. Originality/value: The article may help leaders of AECO firms, industry associations, policymakers and academia to take steps in relevant directions to enable digital transformation.

Abstract

Aims The use of metagenomics for pathogen identification in clinical practice has been limited. Here we describe a workflow to encourage the clinical utility and potential of NGS for the screening of bacteria, fungi, and antimicrobial resistance genes (ARGs). Methods and results The method includes target enrichment, long-read sequencing, and automated bioinformatics. Evaluation of several tools and databases was undertaken across standard organisms (n  = 12), clinical isolates (n  = 114), and blood samples from patients with suspected bloodstream infections (n  = 33). The strategy used could offset the presence of host background DNA, error rates of long-read sequencing, and provide accurate and reproducible detection of pathogens. Eleven targets could be successfully tested in a single assay. Organisms could be confidently identified considering ≥60% of best hits of a BLAST-based threshold of e -value 0.001 and a percent identity of >80%. For ARGs, reads with percent identity of >90% and >60% overlap of the complete gene could be confidently annotated. A kappa of 0.83 was observed compared to standard diagnostic methods. Thus, a workflow for the direct-from-sample, on-site sequencing combined with automated genomics was demonstrated to be reproducible. Conclusion NGS-based technologies overcome several limitations of current day diagnostics. Highly sensitive and comprehensive methods of pathogen screening are the need of the hour. We developed a framework for reliable, on-site, screening of pathogens. [ABSTRACT FROM AUTHOR]

41. Improving Diagnostic and Laboratory Capacity Helps in Control of Infection: an Indian Perspective

Author

Bhattacharya, Sanjay

Abstract

Purpose of Review: To appraise the evidence and recommendations from published medical literature about the importance of clinical microbiology laboratory services in the prevention and control of infection in community and in the healthcare setting especially from the Indian perspective. Recent Findings: Effective infection prevention and control (IPC) is not possible without a functioning microbiology laboratory. Basic microbiology services in a biosafety level 2 facility consisting of light microscopy, blood culture, bacteriology, serology, and tests for certain fungus and mycobacteria (with standard facilities with regard to microscopy, culture) are essential for all tertiary care facilities providing IPC services. In primary and secondary healthcare facilities where microbiology laboratory services are not available in most low- and middle-income countries (LMICs), point of care tests and rapid diagnostic tests which are cost-effective have an important role in IPC and clinical care of patients. Quality assurance of all microbiology tests is important for clinical management and IPC. Summary: Investment in the development of clinical microbiology laboratory infrastructure is essential for IPC and patient care. Surveillance data generated from clinical microbiology services may be used to monitor epidemiological trends of infectious diseases; formulate antimicrobial treatment or prophylactic policies; and assess impact of clinical, antimicrobial stewardship and IPC interventions.

Abstract

Background: Infections by multidrug‐resistant organisms (MDRO) are a major hurdle in hematopoietic stem‐cell transplants (HSCTs). Conditioning regimens lead to mucosal barrier injury, which in‐turn leads to transmigration of gut bacteria and sepsis. Pre‐transplant stool and throat surveillance cultures can guide empirical antibiotic policy during the neutropenic period. In this paper, we document colonization with MDRO in pre‐transplant surveillance cultures and the correlation with bloodstream infections in HSCT patients and analyze transplant outcomes with respect to these infections. Methods: A single‐center, retrospective study on HSCT was performed between January 2021 and December 2021. The incidence of bacterial infections, percentage of MDROs, correlation with pre‐transplant stool/throat surveillance cultures, and their impact on overall 100‐day and post‐100‐day to 6‐month post‐transplant survival were analyzed. Results: Sixty‐four patients were included in the study. Pre‐transplant stool surveillance cultures were positive for MDRO in 85.9% of patients. Almost half (48.5%) of the isolates were positive for carbapenemase‐producing genes (mainly New Delhi metallo‐beta‐lactamase‐1 [NDM‐1] and oxacillinase‐48 [OXA‐48]). Eighteen patients (18/64, 28%) had a positive blood culture for MDRO in the peri‐engraftment neutropenic period. Correlation between surveillance and blood cultures was seen in 61% (11/18) of patients. All‐cause mortality was 14.1% (9/64) and 25% (16/64) in patients at 100 days and 6 months post‐HSCT, respectively. The 100‐day and post‐100‐day all‐cause mortality rates were higher in patients with Gram‐negative MDRO bloodstream infections (p <.012 and <.008, respectively). Conclusion: MDRO infections can adversely affect HSCT outcomes. Pre‐transplant stool and throat surveillance cultures may guide empirical antibiotic policy and lead to favorable transplant outcomes.
