A narrative review on current duodenoscope reprocessing techniques and novel developments.

Duodenoscopy-associated infections occur worldwide despite strict adherence to reprocessing standards. The exact scope of the problem remains unknown because a standardized sampling protocol and uniform sampling techniques are lacking. The currently available multi-society protocol for microbial culturing by the Centers for Disease Control and Prevention, the United States Food and Drug Administration (FDA) and the American Society for Microbiology, published in 2018 is too laborious for broad clinical implementation. A more practical sampling protocol would result in increased accessibility and widespread implementation. This will aid to reduce the prevalence of duodenoscope contamination. To reduce the risk of duodenoscopy-associated pathogen transmission the FDA advised four supplemental reprocessing measures. These measures include double high-level disinfection, microbiological culturing and quarantine, ethylene oxide gas sterilization and liquid chemical sterilization. When the supplemental measures were advised in 2015 data evaluating their efficacy were sparse. Over the past five years data regarding the supplemental measures have become available that place the efficacy of the supplemental measures into context. As expected the advised supplemental measures have resulted in increased costs and reprocessing time. Unfortunately, it has also become clear that the efficacy of the supplemental measures falls short and that duodenoscope contamination remains a problem. There is a lot of research into new reprocessing methods and technical applications trying to solve the problem of duodenoscope contamination. Several promising developments such as single-use duodenoscopes, electrolyzed acidic water, and vaporized hydrogen peroxide plasma are already applied in a clinical setting.

Dynamic coupling between the COVID-19 epidemic timeline and the behavioral response to PAUSE in New York State counties.

Behavioral epidemiology suggests that there is a tight dynamic coupling between the timeline of an epidemic outbreak, and the social response in the affected population (with a typical course involving physical distancing between individuals, avoidance of large gatherings, wearing masks, etc). We study the bidirectional coupling between the epidemic dynamics of COVID-19 and the population social response in the state of New York, between March 1, 2020 (which marks the first confirmed positive diagnosis in the state), until June 20, 2020. This window captures the first state-wide epidemic wave, which peaked to over 11,000 confirmed cases daily in April (making New York one of the US states most severely affected by this first wave), and subsided by the start of June to a count of consistently under 1,500 confirmed cases per day (suggesting temporary state-wide control of the epidemic). In response to the surge in cases, social distancing measures were gradually introduced over two weeks in March, culminating with the PAUSE directive on March 22nd, which mandated statewide shutdown of all nonessential activity. The mandates were then gradually relaxed in stages throughout summer, based on how epidemic benchmarks were met in various New York regions. In our study, we aim to examine on one hand, whether different counties exhibited different responses to the PAUSE centralized measures depending on their epidemic situation immediately preceding PAUSE. On the other hand, we explore whether these different county-wide responses may have contributed in turn to modulating the counties' epidemic timelines. We used the public domain to extract county-wise epidemic measures (such as cumulative and daily incidence of COVID-19), and social mobility measures for different modalities (driving, walking, public transit) and to different destinations. Our correlation analyses between the epidemic and the mobility time series found significant correlations between the size of the epidemic and the degree of mobility drop after PAUSE, as well as between the mobility comeback patterns and the epidemic recovery timeline. In line with existing literature on the role of the population behavioral response during an epidemic outbreak, our results support the potential importance of the PAUSE measures to the control of the first epidemic wave in New York State.

Governance aspects of large-scale implementation of automated surveillance of healthcare-associated infections.

OBJECTIVES: Surveillance of healthcare-associated infections (HAI) is increasingly automated by applying algorithms to routine-care data stored in electronic health records. Hitherto, initiatives have mainly been confined to single healthcare facilities and research settings, leading to heterogeneity in design. The PRAISE network - Providing a Roadmap for Automated Infection Surveillance in Europe - designed a roadmap to provide guidance on how to move automated surveillance (AS) from the research setting to large-scale implementation. Supplementary to this roadmap, we here discuss the governance aspects of automated HAI surveillance within networks, aiming to support both the coordinating centres and participating healthcare facilities as they set up governance structures and to enhance involvement of legal specialists. METHODS: This article is based on PRAISE network discussions during two workshops. A taskforce was installed that further elaborated governance aspects for AS networks by reviewing documents and websites, consulting experts and organizing teleconferences. Finally, the article has been reviewed by an independent panel of international experts. RESULTS: Strict governance is indispensable in surveillance networks, especially when manual decisions are replaced by algorithms and electronically stored routine-care data are reused for the purpose of surveillance. For endorsement of AS networks, governance aspects specifically related to AS networks need to be addressed. Key considerations include enabling participation and inclusion, trust in the collection, use and quality of data (including data protection), accountability and transparency. CONCLUSIONS: This article on governance aspects can be used by coordinating centres and healthcare facilities participating in an AS network as a starting point to set up governance structures. Involvement of main stakeholders and legal specialists early in the development of an AS network is important for endorsement, inclusivity and compliance with the laws and regulations that apply.

Repatriation operation in South Australia during the COVID-19 pandemic: initial planning and preparedness.

ABSTRACT: With COVID-19 affecting millions of people around the globe, quarantine of international arrivals is a critical public health measure to prevent further disease transmission in local populations. This measure has also been applied in the repatriation of citizens, undertaken by several countries as an ethical obligation and legal responsibility. This article describes the process of planning and preparing for the repatriation operation in South Australia during the COVID-19 pandemic. Interagency collaboration, development of a COVID-19 testing and quarantining protocol, implementing infection prevention and control, and building a specialised health care delivery model were essential aspects of the repatriation operational planning, with a focus on maintaining dignity and wellbeing of the passengers as well as on effective prevention of COVID-19 transmission. From April 2020 to mid-February 2021, more than 14,000 international arrivals travellers have been repatriated under the South Australian repatriation operations. This paper has implications to inform ongoing repatriation efforts in Australia and overseas in a pandemic situation.

[Patient in the otolaryngology office in the time of the COVID-19 pandemic in the light of current recommendations, legal regulations and authors' own experience]. / Pacjent w gabinecie otolaryngologicznym w dobie pandemii COVID-19 w swietle aktualnych wytycznych, przepisów prawnych i wlasnych doswiadczen.

Generally, COVID-19 is an acute contagious disease caused by the SARS­CoV-2 virus. The main route of human-to-human transmission is through contact with infectious secretions from the respiratory tract. Clinical manifestations vary from mild non-specific symptoms to life-threatening conditions. Since WHO declared COVID-19 a pandemic in March 2020, it has affected many medical, legal, social and economic aspects of everyday life in countries around the world. In this article, the authors present a summary of recommendations for taking care of otorhinolaryngology patients in outpatient settings and the legal basis referring to a risk of infection in doctor's office. In the selection of articles, the authors used English- and Polish-language online medical databases, typing the following keywords: SARS­CoV-2, COVID-19, otolaryngology, endoscopy, personal protective equipment, and legal responsibility of the physician. The mucosa of the upper respiratory tract is a potential site of virus replication. The specificity of an ear, nose and throat (ENT) examination and a direct patient-doctor contact favor the transmission of the infection. The authors discussed the elements of self-protection of medical personnel and the legal aspects a risk of the patient contracting the infection in the otolaryngology office. In the case of a direct contact with the patient, the following medical personal protective equipment is required: a cap, a mask with an FFP-2 filter, goggles, an apron and gloves. If, during the visit, exposure to secretions or aerosol from the respiratory tract is expected, the personnel should additionally wear a visor and a waterproof apron. The patient's visit in the clinic should be preceded by telemedicine consultation. Patients should be screened prior to having a direct contact with a physician, using a short patient questionnaire. The questionnaire may consist of simple questions about the characteristic symptoms of the SARS­CoV-2 infection and exposure to a sick person in the past 14 days. The question of staying in the areas of a high infection risk appears of little importance in view of the whole of Poland being perceived as constituting such an area. Due to the spread of the SARS­CoV-2 virus, new procedures for providing medical services have been introduced. In the case of claims on the part of the patient, the only protection the medical personnel or facility can provide is confirmation of scrupulous compliance with medical procedures .

COVID-19: A review and considerations for the resumption of activities in an IVF laboratory and clinic in Brazil.

COVID-19 has caused radical effects on the daily lives of millions of people. The causal agent of the current pandemic is SARS-CoV-2, a virus that causes symptoms related to the respiratory system, leading to severe complications. In the in vitro fertilization (IVF) universe, there are several protocols for infection control and laboratory safety. Some professional associations have issued guidelines recommending measures involving patient flow and IVF practices. This study presents a review and considerations for the resumption of activities in IVF laboratories and clinics in Brazil during the COVID-19 pandemic, according to the guidelines and statements from professional organizations and societies in reproductive medicine.

A Less Restrictive Policy for Liver Transplantation in Coronavirus Disease 2019 Positive Patients, Based Upon Cycle Threshold Values.

Coronavirus disease 2019 drastically impacted solid organ transplantation. Lacking scientific evidence, a very stringent but safer policy was imposed on liver transplantation (LT) early in the pandemic. Restrictive transplant guidelines must be reevaluated and adjusted as data become available. Before LT, the prevailing policy requires a negative severe acute respiratory syndrome coronavirus 2 real-time polymerase chain reaction (RT-PCR) of donors and recipients. Unfortunately, prolonged viral RNA shedding frequently hinders transplantation. Recent data reveal that positive test results for viral genome are frequently due to noninfectious and prolonged convalescent shedding of viral genome. Moreover, studies demonstrated that the cycle threshold of quantitative RT-PCR could be leveraged to inform clinical transplant decision-making. We present an evidence-adjusted and significantly less restrictive policy for LT, where risk tolerance is tiered to recipient acuity. In addition, we delineate the pretransplant clinical decision-making, intra- and postoperative management, and early outcome of 2 recipients of a liver graft performed while their RT-PCR of airway swabs remained positive. Convalescent positive RT-PCR results are common in the transplant arena, and the proposed policy permits reasonably safe LT in many circumstances.

Which COVID policies are most effective? A Bayesian analysis of COVID-19 by jurisdiction.

This paper reports the results of a Bayesian analysis on large-scale empirical data to assess the effectiveness of eleven types of COVID-control policies that have been implemented at various levels of intensity in 40 countries and U.S. states since the onset of the pandemic. The analysis estimates the marginal impact of each type and level of policy as implemented in concert with other policies. The purpose is to provide policymakers and the general public with an estimate of the relative effectiveness of various COVID-control strategies. We find that a set of widely implemented core policies reduces the spread of virus but not by enough to contain the pandemic except in a few highly compliant jurisdictions. The core policies include the cancellation of public events, restriction of gatherings to fewer than 100 people, recommendation to stay at home, recommended restrictions on internal movement, implementation of a partial international travel ban, and coordination of information campaigns. For the median jurisdiction, these policies reduce growth rate in new infections from an estimated 270% per week to approximately 49% per week, but this impact is insufficient to prevent eventual transmission throughout the population because containment occurs only when a jurisdiction reduces growth in COVID infection to below zero. Most jurisdictions must also implement additional policies, each of which has the potential to reduce weekly COVID growth rate by 10 percentage points or more. The slate of these additional high-impact policies includes targeted or full workplace closings for all but essential workers, stay-at-home requirements, and targeted school closures.

Game analysis on the evolution of COVID-19 epidemic under the prevention and control measures of the government.

In this paper, the interaction strategies and the evolutionary game analysis of the actions taken by the government and the public in the early days of the epidemic are incorporated into the natural transmission mechanism model of the epidemic, and then the transmission frequency equations of COVID-19 epidemic is established. According to the cumulative confirmed cases of COVID-19 in the UK and China, the upper limit of the spread of COVID-19 in different evolutionary scenarios is set. Using SPSS to perform logistic curve fitting, the frequency fitting equations of cumulative confirmed cases under different evolution scenarios are obtained respectively. The analysis result shows that the emergency response strategy adopted by the government in the early days of the epidemic can effectively control the spread of the epidemic. Combined with the transmission frequency equation of COVID-19 epidemic, measures taken by the government are analyzed. The influence of each measure on the frequency variable is judged and then the influence on the spread of the epidemic is obtained. Finally, based on the above analysis, the government is advised to adhere to the principles of scientific, initiative and flexibility when facing major epidemics.

Policies Tackling the COVID-19 Pandemic: A Sociopolitical Perspective from Taiwan.

As people around the world anxiously watched the early development of the novel coronavirus disease 2019 (COVID-19) pandemic, they expected Taiwan be one of the hardest-hit countries. Yet, to the surprise of many onlookers, the country has managed to keep severe acute respiratory syndrome coronavirus 2 at bay. Taiwan has taken decisive actions to prevent spread of the virus since the very beginning of the epidemic. While the fight is still ongoing, we provide an overview of major policies and strategies undertaken in Taiwan to tackle the COVID-19 pandemic, analyzing them from a sociopolitical perspective. We found that the centralized and professional leadership, democratic and accountable political culture, and vibrant civil society and broad social participation are the key features of disease control in Taiwan.

The Importance of Mandatory COVID-19 Diagnostic Testing Prior to Release from Quarantine.

A 14-day quarantine is implemented in many countries in response to the coronavirus disease pandemic. Korea implemented a mandatory quarantine for those who had close contact with infected patients and those returning from abroad. The present study explored the implications of mandatory coronavirus disease 2019 testing before releasing individuals from the 14-day quarantine in Incheon, Korea. From February 11 to July 5, 2020, 19,296 people were self-quarantined, and 56 (0.3%) of them were confirmed cases of COVID-19. Twenty (35.7%) were identified through the reporting of symptoms during quarantine, and 32 (57.1%) were identified using mandatory pre-release RT-PCR tests. Among the 32, 14 (25%) individuals reported mild symptoms and 18 (32.1%) were asymptomatic. It is suggested that mandatory diagnostic testing prior to release and the symptom-based surveillance after the 14-day quarantine may help control delayed or asymptomatic COVID-19 cases.

Recent Actions by the US Food and Drug Administration: Reducing the Risk of Infection from Reprocessed Duodenoscopes.

In addition to technological advancements, engagement and collaboration among the wider community of stakeholders will be beneficial toward reducing the risk of infection from reprocessed duodenoscopes. Such a community can raise awareness of the importance of duodenoscope cleaning, work to improve reprocessing training, identify the most pressing unanswered questions that merit further research, and develop tools that can be used by health care facilities to improve the quality of reprocessing at their sites. The Food and Drug Administration looks forward to working with the community to further reduce the risk of infections from reprocessed duodenoscopes.

[Occupational safety in the treatment of COVID-19 patients : Relevant laws and regulations for the treating personnel]. / Arbeitsschutz bei der Versorgung von COVID-19-Patienten : Relevante Gesetze und Regelungen für das versorgende Personal.

The intensive medical care of COVID-19 patients presents the deployed personnel with as yet unknown challenges. For example, protective equipment is now being extensively used, which was otherwise only used in selected situations. Working in such an environment is to be evaluated differently under the aspect of occupational safety than other patient care, especially as more than 1900 suspected cases of a SARS-CoV-19 occupational disease were reported among healthcare workers in Germany. Even in a pandemic, the legal requirements remain valid and personal protective equipment (PPE) has to comply with given standards. The use of FFP3 masks is required in aerosol-forming situations, such as endotracheal intubation or bronchoscopy. In contrast to surgical face masks, there is a maximum wearing time for FFPs masks. Furthermore, in a pandemic there is a basic danger of PPE shortage and recycling of face masks is under discussion. Therefore, usage of non-EU certified PPE may come into effect but this has to follow the requirements defined by European regulations. The aim of this article is to provide an overview of the currently relevant rules and regulations in Germany.
