The use of animals as scientific models is argued to be crucial for producing new scientific and medical knowledge and clinical treatments. However, animal research continues to raise socio-ethical concerns. In recent years, there has been a push for openness amongst the life science community, with the aim of increasing the transparency of animal research to wider publics. Yet, how this push for openness is experienced by those responsible for the care and welfare of research animals requires further study. This paper draws upon qualitative interviews with Named Veterinary Surgeons (NVS) in the UK and explores how they practise openness, avoid openness, and, at times, challenge the way their role is represented within openness agendas. Overall, this social scientific analysis reveals that the current openness agenda has the potential to create tensions for professionals, as they seek to manage regulatory and public imaginaries of the veterinary identity alongside the animal research controversy. The paper concludes by arguing for a culture of dialogue, where openness includes allowing those with responsibilities for animal welfare to express ambivalence or concern about their own role. Finally, the paper calls for sustained academic work on relations between the veterinary profession and wider society, particularly areas that involve contested practices in which care and harm may coincide.
This chapter provides guidance on how to send specimens to a virology laboratory, including the need to provide full and accurate patient information, relevant clinical information, how to package and transport specimens and the need to send the correct specimens.
This chapter deals with quality control in the virology laboratory, including quality control and quality assurance. It stresses the need to conduct regular audits of the service to maintain quality standards and the need for accredition schemes (e.g. UKAS). Sources of errors in the laboratory and factors associated with technical quality are also discussed.
This chapter deals with public health and pandemic preparedness. It recognises the five stages of a new pandemic (detection, assessment, treatment, escalation and recovery). The chapter also deals with the issue of laboratory preparedness and the need to maintain a critical mass of laboratory and skilled staff expertise at all times in order to be able to respond rapidly and effectively to a new emerging pandemic.
As in other sciences, an economic experiment is an artificial situation created by a researcher for the purpose of answering one or more scientific questions. Experiments of various types are used in economics to understand the causes of poverty and how it might be alleviated. The methods can identify causal relationships between variables and thereby isolate factors that can lead to poverty as well as to document the behavioral consequences of poverty. Experiments can also be used to provide test beds for proposed policies to alleviate poverty. This essay describes a variety of ways in which experiments have been employed to understand and combat poverty. A line of laboratory experiments that considers which economic institutions are conducive to economic growth is discussed in detail. The results show that decentralized markets are conducive to allowing an economy to operate as efficiently as it can. However, in an economy with a theoretical “poverty trap,” the market works more efficiently if accompanied by a democratic voting process and freedom of communication.
Rats are a well-understood and widely used laboratory species that should be provided with environmentally enriched caging in line with modern animal welfare guidelines. This paper reviews which sources of enrichment are effective and should be prioritised, and how methods for providing enrichment might be selected using rats’ preferences as a guide. Rats demonstrate high demand for social contact and prefer larger cages, and cages with shelters, nesting material and foraging devices. Rats also discriminate between different methods of providing a given type of enrichment. It is clear that rats should be provided with enrichments such as social contact and shelter, and, in fact, that these should probably be considered basic husbandry requirements rather than optional improvements. It is still difficult, however, for animal caretakers to access proven, standardised methods for providing appropriately enriched caging, and the level of enrichment routinely provided to most rats in the laboratory appears to be low. Further research is required to assess the impact of enrichment upon research variables and to develop commercially viable enrichment products for rats in the laboratory.
A study was carried out in Australia and the UK of the legislation and procedures relating to the welfare and use of animals in scientific research. In Australia, a National Code of Practice for the Care and Treatment of Laboratory Animals has been adopted and it is a legal obligation for all Institutions to adhere to the Code. Each institution has an Animal Ethics Committee (AEC) responsible for ethical review and animal welfare which must include, within certain stipulated parameters, a veterinarian, a research scientist, a member of a rights/welfare organisation and an additional lay member. In the UK the situation is different, as the Home Office directly administers the law regarding the use of animals in research. In April 1999 the Ethical Review Process (ERP) was introduced; every Institution must establish an ERP which must include a named veterinarian and representatives from the Animal Care and Welfare Officers and others. In both countries great emphasis is placed on the principles of replacement, reduction and refinement in experimental research. Substantial differences in culture and ethical review structure between the two countries are identified. However, various recommendations are outlined, based on the Australian experience, to build on existing structures and further develop the UK ERP. These recommendations should be seen as long-term aims and seek to further improve animal welfare through facilitating communication, increasing accountability and creating an environment conducive to open discussion.
In this article we examine how a leading Israeli hospital gradually became a large biomedical research facility, resembling a huge laboratory. For Chaim Sheba (1908-1971), the founder and first director of Tel-Hashomer Hospital, the massive immigration to Israel in the 1950s was a unique opportunity for research of diverse human populations, especially Jews who had arrived to Israel from Asia and Africa. The paper focuses on the way research and medical practices were integrated and their boundaries blurred, and studies the conditions under which an entire hospital became a research field. Using the case of one of Israel’s prominent medical institutes, we explore and expand upon the idea of “the hospital as a laboratory,” arguing that, for Sheba, it was not only the hospital but the entire country that functioned as a great research site—a vast laboratory that “had no walls.”
Integrating an appreciation of natural behavior into laboratory studies, and laboratory techniques into field studies allows researchers to examine and control proximate factors while identifying adaptive problems faced by particular species. This focus reveals both important similarities and differences across phylogenetic lineages. Carnivores other than canids have been relatively neglected in the study of cognition. An examination of members of the ursid family reveals the important role of foraging ecology in shaping learning and memory in both wild and captive settings. Whereas top-down approaches tend to be anthropocentric, a bottom-up approach focused on the unique capacities and traits of individual species bears the most fruit in terms of understanding the selective pressures responsible for the emergence and maintenance of those traits.
For millions of people, normal eating is impossible, including persons with chronic bowel disorders, individuals suffering from extensive burns, and patients recovering from major surgery. Not only adults but also newborns and young children are vulnerable. Stanley Dudrick was not the first surgeon to confront this grave reality, but he was the first to devise a highly effective method to feed those who would otherwise succumb from undernourishment. The method is known as Total Parenteral Nutrition. It involves injecting liquid food directly into the bloodstream by a tube connected to a vein, thus bypassing the stomach and small intestine. In the 1960s, medical professionals claimed that feeding a patient entirely by vein was impossible; even if possible, it would be impractical; and even if practical, it would be unaffordable. Through tenacious experimental research, Dudrick proved them wrong, in the process giving life and hope to many who would otherwise have perished.
Since its promotion in 1974, the Heimlich Maneuver has been an invaluable first-aid procedure, which is believed to have saved the lives of countless thousands of choking victims. Henry Heimlich’s life story is one motivated by saving people from unnecessary death and injury. His painstaking development of the abdominal thrust technique is an arresting tale in and of itself. But, so too were his determined efforts to popularize the method in order that ordinary citizens too could become lifesaving heroes. Nevertheless, suffocation by ingestion or inhalation remains the fourth most common cause of preventable death in the United States, requiring that the general public be simply and properly taught on a continuing basis how to administer this vital technique.
Behaviour can be recorded in either the laboratory or the field. In either setting, it can be recorded using standardised behavioural tests that elicit specific behaviour, or by observing freely-behaving subjects. Observation requires decisions about which subjects to observe (sampling rules) and how to record their behaviour (recording rules). There are four sampling rules: ad libitum sampling, focal sampling, scan sampling and behaviour sampling. There are two basic types of recording rule: continuous recording and time sampling; the latter can be further divided into instantaneous sampling and one–zero sampling. Continuous recording is more demanding for the observer but is the only recording method that produces true frequencies and durations. Estimates of frequencies and durations derived from time sampling will be more accurate if the sample interval is short relative to the mean duration of the behaviour. One–zero sampling is likely to yield biased estimates of frequency and duration.
Successful assisted reproduction treatment is critically dependent on consistent laboratory performance. Each laboratory process, from collection of oocytes and preparation of sperm for use in fertilisation in vitro, through embryo culture, assessment, selection for transfer, biopsy for genetic testing, to the storage (cryopreservation) of gametes and embryos for use in later treatment, carries an inherent risk of damage, whether mechanical or through exposure to suboptimal conditions outside the body, with consequences for the chance of successful clinical outcome. Training, competency in specific, unique technical skills and consistent performance of all laboratory practitioners are vital in the ART laboratory. Procedures must be carried out meticulously, adhering to standard operating procedures, with precise attention to detail. Strict adherence to guidelines issued by regulatory and professional bodies is necessary and essential in order to minimise risk and maximise performance. The implementation of a Quality Management System ensures consistent, optimised performance, and facilitates risk assessment and root cause analyses.
The COVID-19 pandemic has had a major impact on clinical practice. Safe standards of practice are essential to protect health care workers while still allowing them to provide good care. The Canadian Society of Clinical Neurophysiologists, the Canadian Association of Electroneurophysiology Technologists, the Association of Electromyography Technologists of Canada, the Board of Registration of Electromyography Technologists of Canada, and the Canadian Board of Registration of Electroencephalograph Technologists have combined to review current published literature about safe practices for neurophysiology laboratories. Herein, we present the results of our review and provide our expert opinion regarding the safe practice of neurophysiology during the COVID-19 pandemic in Canada.
Responding to the extreme scarcity of medical resources during the early outbreak of the coronavirus disease (COVID-19) in Wuhan, China, an emergency specialist hospital of Leishenshan started to construct on January 26, 2020, and accommodate patients on February 6, 2020. The clinical laboratory center of Leishenshan Hospital (CLCLH) was constructed at the same time within 11 days to support the treatment of inpatients in Leishenshan Hospital and the testing of suspected patients from different fever clinics in Wuhan. The CLCLH could perform a total of 320 clinic, 299 biochemistry, 31 microorganism, and 47 infection and immunity examinations per day. It could also complete an average of 239 nucleic acid tests and 118 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody examinations per day. No suspected cases were documented among the health care workers during the operation of the CLCLH. The construction and operation experiences of the CLCLH is provided in this study and might be used by other countries as reference. The content of this study is divided into 4 parts: (1) the establishment of the CLCLH, including its layout and medical resource allocation; (2) the major testing items; (3) the specific procedure of COVID-19 indicator examination; and (4) the standardized personal protection measures.
Clinical diagnostics in sudden onset disasters have historically been limited. We set out to design, implement, and evaluate a mobile diagnostic laboratory accompanying a type 2 emergency medical team (EMT) field hospital.
Methods:
Available diagnostic platforms were reviewed and selected against in field need. Platforms included HemoCue301/WBC DIFF, i-STAT, BIOFIRE FILMARRAY multiplex rt-PCR, Olympus BX53 microscopy, ABO/Rh grouping, and specific rapid diagnostic tests. This equipment was trialed in Katherine, Australia, and Dili, Timor-Leste.
Results:
During the initial deployment, an evaluation of FilmArray tests was successful using blood culture identification, gastrointestinal, and respiratory panels. HemoCue301 (n = 20) hemoglobin values were compared on Sysmex XN 550 (r = 0.94). HemoCue WBC DIFF had some variation, dependent on the cell, when compared with Sysmex XN 550 (r = 0.88-0.16). i-STAT showed nonsignificant differences against Vitros 250. Further evaluation of FilmArray in Dili, Timor-Leste, diagnosed 117 pathogens on 168 FilmArray pouches, including 25 separate organisms on blood culture and 4 separate cerebrospinal fluid pathogens.
Conclusion:
This mobile laboratory represents a major advance in sudden onset disaster. Setup of the service was quick (< 24 hr) and transport to site rapid. Future deployment in fragmented health systems after sudden onset disasters with EMT2 will now allow broader diagnostic capability.
The Spanish patent system in the twentieth century has been defined by the incorporation of technologies and regulations. Patents have been intermediaries, and their regulation has been subject to complaints, some of which came from abroad. To analyse this reality, I propose two case studies that suggest different patent cultures, subject to specific times and places. The first case, the arrival in Spain of the first North American patents to protect production of penicillins, shows the mediation role patents played. Patents connected practices, languages, and interests from different Spanish and North American professional communities – clinical, industrial, and political – at the end of the 1940s and beginning of the 1950s. The second case, the launch on the market of a Spanish patent for a DNA polymerase, product of research done in a Spanish laboratory and patented in the USA in 1988, shows rather local regulations and the limits on international harmonization. The political, social, and economic changes that protection systems demand differ from one place to another, and do not always coincide with voices calling for harmonization.
Chapter Four focuses on the experimental approaches of physical-psychical scientists to psychical phenomena.It focuses on four key examples from the 1870s-1890s: William Crookes’s investigations of ‘psychic force’ ; Crookes and Cromwell Varley’s electrical tests of mediumship; the SPR’s studies of Reichenbach’s ‘od’ ; and Oliver Lodge and Benjamin Davies’s ideas about and experimental tests of telekinesis.The chapter shows the extraordinary lengths to which physical-psychical scientists went to achieve greater control over, to measure and record psychical effects, and to turn domestic seances into sites of experimental physics.The limited effectiveness of this work was partly due to perceived flaws in experimental design, a lack of suitable experimental subjects (mediums), and because physical-psychical scientists believed their professional and intellectual goals were better served by focusing experimental research on purely physical topics.
In resource-constrained settings, primary health centers (PHCs) are critical for universal health coverage. Laboratory service is one of its important components. While PHC and its performance are focused, its laboratory service has been neglected in developing countries like India.
Aim:
To determine the role of different level of PHC laboratory services on the overall PHC performance.
Methods:
Cross-sectional study based on 42 PHCs of Osmanabad District, Maharashtra, India was performed. The study used levels of laboratory services in PHC as independent parameter and PHC outpatient department (OPD) visits per day (≤ 80 versus > 80) as dependent parameter. The control parameters used in the study were number of medical doctors, availability of laboratory technicians (LTs) and population coverage by PHC. Field visit was done to collect data on levels of laboratory services, but secondary source was used for other parameters. The logistic regression analysis was performed in study.
Findings:
The study found variation in PHC population coverage (10 788–74 702) and OPD visits per day (40–182) across PHC. Strong positive association was observed between levels of laboratory services and number of OPD visits per day in PHC. PHC offering both malaria and tuberculosis in-house testing had higher odds (4.81) of getting more OPDs (≥ 80 OPD visits per day) as compared to PHC not offering in-house testing facility for malaria and tuberculosis. This association was stronger in PHCs with lower population coverage (0–75 quartile) as compared to PHCs with higher population coverage (75–100 quartile).
Conclusion:
Focus on laboratory services is needed to enhance the existing PHCs performance. Skill-up gradation of existing LT could help in improving the contribution of the existing laboratories in PHC functioning.
