COVID-19 pandemic response and Field Epidemiology and Laboratory Training Programs in ECOWAS.

The COVID-19 pandemic has been persistent with a huge demand for human health resources which is a vital component of its preparedness and response. Globally, the public health workforce through field epidemiology and laboratory training programme (FELTP) has been instrumental to global health security. We determined the status of FELTP in the region and its contributions to the COVID-19 pandemic response in the ECOWAS region. We conducted a desk review, shared a questionnaire among member states and organized a two-day online regional consultative meeting on field epidemiology training on 30th-31st March 2022 during which there were presentations, group discussions and deliberations on the status and contribution of FETP during the COVID-19 pandemic. Data collected were analyzed in themes. All countries in the ECOWAS region had established at least one tier of FELTP, 11 (73.3%) had established two tiers of FELTP and only 3 (20.0%) had established all three tiers of the program. Despite the pandemic, the cumulative number of graduates increased from 2996 to 4271 frontline, 41 to 380 intermediate, and 409 to 802 for advanced FELTP between 2019 and 2022. However, the progress has been disproportionate across countries. The key activities supported through FELTP graduates included pandemic response coordination, surveillance, data collection/management, laboratory support, case management, risk communication, infection prevention and control, COVID-19 vaccination, and research. Despite improvements in the FELTP in the Economic Community of West African States (ECOWAS) region, there is a need for continuous stakeholder engagement for its implementation, resource mobilization for sustainability, and leveraging critical partnerships.

Strengthening the US Public Health Lab System: Summary of Coronavirus Disease (COVID-19) After Action Review Workshop.

CONTEXT: The COVID-19 pandemic highlighted the significance of public health laboratories across the United States, while also revealing weaknesses in the laboratory system. OBJECTIVE: To identify actionable recommendations for building a more resilient public health laboratory system based on previously published lessons learned from COVID-19. DESIGN, SETTING, AND PARTICIPANTS: In April 2023, the Association of Public Health Laboratories, in cooperation with RAND , convened a 1.5-day after action review workshop of approximately 30 public health laboratory stakeholders to reevaluate priorities, improve processes, and affect policies. MAIN OUTCOME MEASURES: Analysis of workshop discussions identified 5 priority areas and 19 recommendations related to clarifying laboratories' unique role and promoting workforce capacity/agility, technology, and collaboration with governmental and nongovernmental partners. RESULTS: Within the identified priority areas, workshop participants described how the recommendations would address challenges encountered during COVID-19 and contribute to strengthening the system. CONCLUSIONS: As the risk of novel infectious diseases persists and grows, the importance of maintaining laboratory response capabilities is likely to increase. Addressing the system's weaknesses will require active engagement of laboratories and the many stakeholders who depend on them, along with consistent, adequate funding to strengthen and sustain capabilities.

Feedback from the Science Café roundtables at the ninth European Bioanalysis Forum Young Scientist Symposium: optimizing the work-life balance in a bioanalytical laboratory.

As part of the European Bioanalysis Forum's continued commitment to develop young scientists beyond their scientific skills, we also focus on soft skills and a community responsibility during the Young Scientist Symposia, with the Science Café. In previous years, we have focused on topics such as sustainability (green lab) or the impact of the COVID-19 pandemic on career development. At the ninth Young Scientist Symposium, the Science Café roundtables focused on the work-life balance and how caring for it can be beneficial for both the individual and the company. Feedback from a premeeting survey and from the discussions during the roundtables can be an important addition to personal and professional development. If organizations are not already focusing on the importance of a healthy work-life balance, they can be inspired to include some aspects of the outcome of the Science Café discussions when developing their staff toward future (scientific) leadership.

Recruiting and cultivating future leaders in laboratory science.

PURPOSE OF REVIEW: Technological in-vitro fertilization (IVF) advancements originate in the embryology laboratory, and are accompanied by increased regulatory oversight and risk management. Stakes have never been higher or the need greater for the recruitment and cultivation of leaders in laboratory science to navigate the direction of IVF. Current thought leaders in state-of-the-art laboratories must prioritize this mission to optimize and preserve the future of IVF. RECENT FINDINGS: Leaders in laboratory science must be able to speak to patients, the lay public, business leaders, scientific colleagues and clinical embryologists. While technically gifted, laboratory leaders may benefit from leadership training. Recruitment of scientists into IVF is currently challenging due to a lack of branding and no clear pipeline for new scientists to enter the field. Once recruited however, cultivation of new leaders requires coaching and skill acquisition over time, in order to create multifaceted laboratory leadership. SUMMARY: Laboratory leaders are typically recruited based on education and experience to lead teams of embryologists. These leaders will adopt new technologies in the laboratory. Therefore, laboratory leaders play a powerful role in IVF requiring leadership skills ultimately driving patient outcomes. These laboratory directors must possess innate leadership abilities or learn how to lead their teams.

The challenges for implementing Good Clinical Practices in the bioanalytical laboratory: a discussion paper from the European Bioanalysis Forum.

This manuscript reports back from the discussion in the European Bioanalysis Forum community on the challenges observed when implementing Good Clinical Practices in the bioanalytical laboratory. It is not intended to challenge any regulatory requirements but to open a discussion on where the bioanalytical community sees ambiguities on implementing Good Clinical Practices or areas where expectations are either felt not being owned by Bioanalysis or where Good Clinical Practices requirements are at risk of getting contaminated with requirements originating from Good Laboratory Practices. In addition to this, the discussions focused on three additional main challenges: the informed consent withdrawal, expedited reporting of unexpected results and the risk-based approach to quality management, The European Bioanalysis Forum community is continuing discussions, but already this manuscript should help to appreciate the challenges and to try and resolve them, involving all stakeholders.

Ongoing Cooperative Engagement Facilitates Agile Pandemic and Outbreak Response: Lessons Learned Through Cooperative Engagement Between Uganda and the United States.

Pathogens threaten human lives and disrupt economies around the world. This has been clearly illustrated by the current COVID-19 pandemic and outbreaks in livestock and food crops. To manage pathogen emergence and spread, cooperative engagement programs develop and strengthen biosafety, biosecurity, and biosurveillance capabilities among local researchers to detect pathogens. In this case study, we describe the efforts of a collaboration between the Los Alamos National Laboratory and the Uganda Virus Research Institute, the primary viral diagnostic laboratory in Uganda, to implement and ensure the sustainability of sequencing for biosurveillance. We describe the process of establishing this capability along with the lessons learned from both sides of the partnership to inform future cooperative engagement efforts in low- and middle-income countries. We found that by strengthening sequencing capabilities at the Uganda Virus Research Institute before the COVID-19 pandemic, the institute was able to successfully sequence SARS-CoV-2 samples and provide data to the scientific community. We highlight the need to strengthen and sustain capabilities through in-country training, collaborative research projects, and trust.

Comprehensive Planning of Laboratory Equipment Based on Genetic Algorithms.

Laboratory equipment planning is a very important task in modern enterprise management. Laboratory equipment planning by computer algorithm is a very complex NP-hard combinatorial optimization problem, so it is impossible to find an accurate algorithm in polynomial time. In this study, an improved genetic algorithm is used to solve and analyze the comprehensive planning of laboratory equipment. After analyzing the traditional heuristic algorithm and genetic algorithm to solve the simple laboratory equipment planning problem, the simple laboratory equipment planning is designed and implemented according to the principle of the heuristic algorithm. Finally, the algorithm is implemented in Python. A general equipment planning based on genetic algorithm with two selection operators is realized. Two constraints of test start and completion time are given. In the scenario of using multiple test equipment for a test project, the possible solutions of laboratory equipment planning under given constraints are analyzed. The efficiency coefficient is not necessarily a constant, it is related to the output characteristics of energy equipment. Three independent planning algorithms are used to solve the actual test requirements. One is the planning method based on manual test scheduling in the test cycle of experimental instruments, the other is the genetic algorithm for gene location crossover operator, and the third is the genetic algorithm for experimental part crossover operator. The planning solutions obtained by the three algorithms are compared from three aspects: the shortest time to complete the test, the calculation time of the algorithm, and the utilization of the test equipment.

Preclinical coronavirus studies and pathology: Challenges of the high-containment laboratory.

The COVID-19 pandemic has highlighted the critical role that animal models play in elucidating the pathogenesis of emerging diseases and rapidly analyzing potential medical countermeasures. Relevant pathologic outcomes are paramount in evaluating preclinical models and therapeutic outcomes and require careful advance planning. While there are numerous guidelines for attaining high-quality pathology specimens in routine animal studies, preclinical studies using coronaviruses are often conducted under biosafety level-3 (BSL3) conditions, which pose unique challenges and technical limitations. In such settings, rather than foregoing pathologic outcomes because of the inherent constraints of high-containment laboratory protocols, modifications can be made to conventional best practices of specimen collection. Particularly for those unfamiliar with working in a high-containment laboratory, the authors describe the logistics of conducting such work, focusing on animal experiments in BSL3 conditions. To promote scientific rigor and reproducibility and maximize the value of animal use, the authors provide specific points to be considered before, during, and following a high-containment animal study. The authors provide procedural modifications for attaining good quality pathologic assessment of the mouse lung, central nervous system, and blood specimens under high-containment conditions while being conscientious to maximize animal use for other concurrent assays.

More Laboratory Simulations-Fewer Brain Complications: Prospects from the First Neurosurgery Laboratory in Iraq.

BACKGROUND: The intensive training requirements needed to achieve the requisiste microneurosurgical milestones makes proper training and skill acquisition a challenge to the novice neurosurgeon. This problem is compounded in low- and middle-income nations, where neurosurgery is subject to a myriad of human and financial resource constraints. A temporary solution may be provided by low-cost laboratories that are adaptive to local needs. METHODS: The "HOZ NeuroSurgery LAB" is a nonprofit facility dedicated to microneurosurgery education and skills training. The laboratory, established in June 2015, is housed at the Neurosurgery Teaching Hospital in Baghdad, Iraq. It operates under the motto "More Laboratory Simulation-Fewer Brain Complications.". The fundamental infrastructure of the facility consists of a relatively inexpensive microscope, indigenous locally created training equipment, and animal-based models. RESULTS: Since its inception, this lab has functioned as a hub for resident education and microneurosurgery service, in addition to contributing to the specialty's academic output in the nation. The lab is directly responsible for training 4 vascular neurosurgeons who are currently directing the nation's first organized neurovascular service. Also, it has delivered 53 microneurosurgery skills courses, coordinated 8 student neurosurgery elective cycles with a total of 532 participants, and published approximately 70 research articles. CONCLUSIONS: Our experience may serve as a model for other low- and middle-income countries interested in using the principle of "doing more with less" to overcome some of the challenges associated with microneurosurgery in these parts of the world.

The in vitro fertilization laboratory: teamwork and teaming.

Delivery of fertility treatment involves both teamwork within a discipline as well as teaming across multiple work areas, such as nursing, administrative, laboratory, and clinical. In contrast to small autonomous centers, the in vitro fertilization (IVF) laboratory team in large clinics must function both as a team with many members and a constellation of teams to deliver seamless, safe, and effective patient-centered care. Although this review primarily focuses on teamwork within the IVF laboratory, which comprises clinical laboratory scientists and embryologists who perform both diagnostic and therapeutic procedures, it also discusses the laboratory's wider role with other teams of the IVF clinic, and the role of teaming (the ad hoc creation of multidisciplinary teams) to function highly and address critical issues.

Rapid establishment of a frontline field laboratory in response to an imported outbreak of Ebola virus disease in western Uganda, June 2019.

The Democratic Republic of the Congo (DRC) declared an Ebola virus disease (EVD) outbreak in North Kivu in August 2018. By June 2019, the outbreak had spread to 26 health zones in northeastern DRC, causing >2,000 reported cases and >1,000 deaths. On June 10, 2019, three members of a Congolese family with EVD-like symptoms traveled to western Uganda's Kasese District to seek medical care. Shortly thereafter, the Viral Hemorrhagic Fever Surveillance and Laboratory Program (VHF program) at the Uganda Virus Research Institute (UVRI) confirmed that all three patients had EVD. The Ugandan Ministry of Health declared an outbreak of EVD in Uganda's Kasese District, notified the World Health Organization, and initiated a rapid response to contain the outbreak. As part of this response, UVRI and the United States Centers for Disease Control and Prevention, with the support of Uganda's Public Health Emergency Operations Center, the Kasese District Health Team, the Superintendent of Bwera General Hospital, the United States Department of Defense's Makerere University Walter Reed Project, and the United States Mission to Kampala's Global Health Security Technical Working Group, jointly established an Ebola Field Laboratory in Kasese District at Bwera General Hospital, proximal to an Ebola Treatment Unit (ETU). The laboratory consisted of a rapid containment kit for viral inactivation of patient specimens and a GeneXpert Instrument for performing Xpert Ebola assays. Laboratory staff tested 76 specimens from alert and suspect cases of EVD; the majority were admitted to the ETU (89.3%) and reported recent travel to the DRC (58.9%). Although no EVD cases were detected by the field laboratory, it played an important role in patient management and epidemiological surveillance by providing diagnostic results in <3 hours. The integration of the field laboratory into Uganda's National VHF Program also enabled patient specimens to be referred to Entebbe for confirmatory EBOV testing and testing for other hemorrhagic fever viruses that circulate in Uganda.

Interlaboratory assessment of quantification of SARS-CoV-2 RNA by reverse transcription digital PCR.

The pandemic of the novel coronavirus disease 2019 (COVID-19) has caused severe harm to the health of people all around the world. Molecular detection of the pathogen, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), played a crucial role in the control of the disease. Reverse transcription digital PCR (RT-dPCR) has been developed and used in the detection of SARS-CoV-2 RNA as an absolute quantification method. Here, an interlaboratory assessment of quantification of SARS-CoV-2 RNA was organized by the National Institute of Metrology, China (NIMC), using in vitro transcribed RNA samples, among ten laboratories on six different dPCR platforms. Copy number concentrations of three genes of SARS-CoV-2 were measured by all participants. Consistent results were obtained with dispersion within 2.2-fold and CV% below 23% among different dPCR platforms and laboratories, and Z' scores of all the reported results being satisfactory. Possible reasons for the dispersion included PCR assays, partition volume, and reverse transcription conditions. This study demonstrated the comparability and applicability of RT-dPCR method for quantification of SARS-CoV-2 RNA and showed the capability of the participating laboratories at SARS-CoV-2 test by RT-dPCR platform.
