Purposeful infection of healthy volunteers with a microbial pathogen seems at odds with acceptable ethical standards, but is an important contemporary research avenue used to study infectious diseases and their treatments. Generally termed ‘controlled human infection studies’, this research is particularly useful for fast tracking the development of candidate vaccines and may provide unique insight into disease pathogenesis otherwise unavailable. However, scarce bioethical literature is currently available to assist researchers and research ethics committees in negotiating the distinct issues raised (...) by research involving purposefully infecting healthy volunteers. In this article, we present two separate challenge studies and highlight the ethical issues of human challenge studies as seen through a well-constructed framework. Beyond the same stringent ethical standards seen in other areas of medical research, we conclude that human challenge studies should also include: independent expert reviews, including systematic reviews; a publicly available rationale for the research; implementation of measures to protect the public from spread of infection beyond the research setting; and a new system for compensation for harm. We hope these additions may encourage safer and more ethical research practice and help to safeguard public confidence in this vital research alternative in years to come. (shrink)

Increased productivity may have negative impacts on farm animal welfare in modern animal production systems. Efficiency gains in production are primarily thought to be due to the intensification of production, and this has been associated with an increased incidence of production diseases, which can negatively impact upon FAW. While there is a considerable body of research into consumer attitudes towards FAW, the extent to which this relates specifically to a reduction in production diseases in intensive systems, and whether (...) the increased incidence of diseases represents a barrier to consumer acceptance of their increased use, requires further investigation. Therefore a systematic review of public attitudes towards FAW was conducted, with a specific focus on production diseases in intensive systems. Four databases were searched to identify relevant studies. A screening process, using a set of pre-determined inclusion criteria, identified 80 studies, with the strength of evidence and uncertainty assessed for each. A thematic analysis led to the identification of 6 overarching themes constructed from 15 subthemes. The results demonstrate that the public are concerned about FAW in modern production systems. Concern varied in relation to age, gender, education and familiarity with farming. Naturalness and humane treatment were central to what was considered good welfare. An evidence gap was highlighted in relation to attitudes towards specific production diseases, with no studies specifically addressing this. However, the prophylactic use of antibiotics was identified as a concern. A number of dissonance strategies were adopted by consumers to enable guilt free meat consumption. (shrink)

This article is about the justifiability of accepting worse cost effectiveness for orphan drugs, that is, treatments for rare diseases, in a publicly financed health care system. Recently, three arguments have been presented that may be used in favour of exceptionally advantageous economic terms for orphan drugs. These arguments share the common feature of all referring to considerations of justice or fairness: the argument of the irrelevance of group size, the argument from the principle of need, and the argument (...) of identifiability. It is argued that all of these arguments fail to support the conclusion that orphan drugs should be subsidized to a larger extent than treatments for common diseases. The argument of the irrelevance fails to distinguish between directly and indirectly relevant considerations of fairness or justice. The recent attempt to revive the moral relevance of identifiability has provided no novel reasons to think that identifiability is morally relevant in itself or due to considerations of fairness and justice. The argument from the principle of need does not fail due to any inherent flaw in the principle as such. Rather, this principle can be interpreted in different ways, and none of these interpretations support exceptionally advantageous terms economically for treating rare diseases specifically. It is concluded that we are awaiting justice based reasons for the preferential treatment of orphan drugs. (shrink)

There is no doubt that custard apple diseases are among the important reasons that destroy the Custard Apple plant and its agricultural crops. This leads to obvious damage to these plants and they become inedible. Discovering these diseases is a good step to provide the appropriate and correct treatment. Determining the treatment with high accuracy depends on the method used to correctly diagnose the disease, expert systems can greatly help in avoiding damage to these plants. The expert system (...) correctly diagnoses Custard Apple disease to make it easier for farmers to find the right treatment based on the appropriate diagnosis. Objectives: A specialized syllable language system was established for the diagnosis of Custard Apple plant disease. (shrink)

Hedgehog is an important morphogenic signal that directs pattern formation during embryogenesis, but its activity also remains present through adult life. It is now becoming increasingly clear that during the reproductive phase of life and beyond it continues to direct cell renewal (which is essential to combat the chronic environmental stress to which the body is constantly exposed) and counteracts vascular, osteolytic and sometimes oncological insults to the body. Conversely, down‐regulation of hedgehog signalling is associated with ageing‐related diseases such (...) as type 2 diabetes, neurodegeneration, atherosclerosis and osteoporosis. Hence, in this essay we argue that hedgehog signalling is not only important at the start of life, but also constitutes an important anti‐geriatric influence, and that enhanced understanding of its properties may contribute to developing rational strategies for healthy ageing and prevention of ageing‐related diseases.Also watch the Video Abstract.

Leishmania major infection of inbred mice leads to a major dichotomous response—death or survival—that depends on the strain of mice. This finding has motivated efforts to locate genetic determinants of disease susceptibility. Genotyping studies have confirmed a complex multilocus trait, but studies directed at the biology of the response suggest identifiable components of susceptibility that may direct the genetic investigations. A confluence of parasite variables—residence in macrophages, class II-dependent immunity, and avoidance of early IL-12 induction—with host factors—a prominent helper T-cell (...) precursor frequency to a dominant parasite epitope and a bias in IL-4 gene activation—conspires to drive an aberrant immune response in animals that suffer fatal disease. These insights may lead to an understanding of factors that focus responses on dominant antigens and that mold the naive T-cell repertoire. Collectively, such factors might contribute to the pathogenesis of other infectious and autoimmune diseases. BioEssays 21:510–518, 1999. © 1999 John Wiley & Sons, Inc. (shrink)

Neurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

Our paper is a comparative analysis of Alexander Dugin's The Fourth Way and Karl Popper's The Open Society. Both works of the two thinkers are viewed as completely concrete (and real) conceptual frameworks, offering two radically different models of perception of the world, the individual and community relations, of the international relations. Our analysis takes into consideration both the internal, that is the “intimate enemies of democracy”, and the new (old) enemies of the open society that “relapse” through the Fourth (...) Way. Our theoretical research is focused on the parallel between the negative starting premises for the functioning of the Open Society – historicism, utopian social engineering, collectivism and chieftainism – studied in relation to the same principles, which, respectively, are the foundation of the Fourth Political Theory. The article also considers another important problem: the thesis, that the internal, autoimmune diseases of the Open Society, are in fact the preconditions, on which the doctrines of its external opponents are based.

One of the central arguments given to resist testing currently healthy, asymptomatic children for adult-onset diseases is that they may be psychologically harmed by the knowledge gained from such tests. In this discussion I examine two of the most serious arguments: children who are tested may face limited futures, and that testing may result in damage to the child’s self esteem . I claim that these arguments do not stand up to critical evaluation. In conclusion, whilst I do not (...) suggest that all at-risk children should be tested for adult-onset diseases we ought to listen carefully to some parental requests for such testing because the putative psychological harms may not be as significant or likely as initially thought. This is because parents generally have the best interests of their children at heart and if they are properly supported and educated about predictive genetic testing and the possible consequences, then the risk of psychological harms occurring may be ameliorated.

: The main contribution of this paper to current philosophical and sociological studies on modeling is to analyze modeling as an object-oriented interdisciplinary activity and thus to bring new insights into the wide, heterogeneous discourse on tools, forms and organization of interdisciplinary research. A detailed analysis of interdisciplinarity in the making of models is presented, focusing on long-standing interdisciplinary collaboration between specialists in infectious diseases, mathematicians and computer scientists. The analysis introduces a novel way of studying the elements of (...) the models as carriers of interdisciplinarity. These elements, being functionally interdependent building blocks, evolve during the modeling work and carry the disciplinary tensions in the process. This shows how the long and challenging process of defining and reformulating the object of research is crucial for understanding the dynamics of interdisciplinarity in the making. (shrink)

A new analysis of the Best Interests Standard is given and applied to the controversy about testing children for untreatable, severe late-onset genetic diseases, such as Huntington's disease or Alzheimer's disease. A professional consensus recommends against such predictive testing, because it is not in children's best interest. Critics disagree. The Best Interests Standard can be a powerful way to resolve such disputes. This paper begins by analyzing its meaning into three necessary and jointly sufficient conditions showing it: is an (...) "umbrella" standard, used differently in different contexts, has objective and subjective features, is more than people's intuitions about how to rank potential benefits and risks in deciding for others but also includes evidence, established rights, duties and thresholds of acceptable care, and can have different professional, medical, moral and legal uses, as in this dispute. Using this standard, support is given for the professional consensus based on concerns about discrimination, analogies to adult choices, consistency with clinical judgments for adults, and desires to preserve of an open future for children. Support is also given for parents' legal authority to decide what genetic tests to do. (shrink)

The study of rare diseases has long been an area of challenge for medical researchers, with agonizingly slow movement towards improved understanding of pathophysiology and treatments compared with more common illnesses. The push towards evidence-based medicine (EBM), which prioritizes certain types of evidence over others, poses a particular issue when mapped onto rare diseases, which may not be feasibly investigated using the methodologies endorsed by EBM, due to a number of constraints. While other trial designs have been suggested (...) to overcome these limitations (with varying success), perhaps the most recent and enthusiastically adopted is the application of artificial intelligence to rare disease data. This paper critically examines the pitfalls of EBM (and its trial design offshoots) as it pertains to rare diseases, exploring the current landscape of AI as a potential solution to these challenges. This discussion is also taken a step further, providing philosophical commentary on the weaknesses and dangers of AI algorithms applied to rare disease research. While not proposing a singular solution, this article does provide a thoughtful reminder that no ‘one-size-fits-all’ approach exists in the complex world of rare diseases. We must balance cautious optimism with critical evaluation of new research paradigms and technology, while at the same time not neglecting the ever-important aspect of patient values and preferences, which may be challenging to incorporate into computer-driven models.

Neglected and tropical diseases, pervasive in developing countries, are important contributors to global health inequalities. They remain largely untreated due to lack of effective and affordable treatments. Resource-poor countries cannot afford to develop the public health interventions needed to control neglected diseases. In addition, neglected diseases do not represent an attractive market for pharmaceutical industry. Although a number of international commitments, stated in the Millennium Development Goals, have been made to avert the risk of communicable diseases, (...) tropical diseases still remain neglected due to delays in international assistance. This delay can be explained by the form international cooperation has generally taken, which is limited to promoting countries’ national interests, rather than social justice at a global level. This restricts the international responsibility for global inequalities in health to a humanitarian assistance. We propose an alternative view, arguing that expanding the scope of international cooperation by promoting shared health and economic value at a global level will create new opportunities for innovative, effective and affordable interventions worldwide. It will also promote neglected diseases as a global research priority. We build our argument on a proposal to replace the patenting system that currently regulates pharmaceutical research with a global fund to reward this research based on actual decreases in morbidity and mortality at a global level. We argue that this approach is beneficent because it will decrease global health inequalities and promote social justice worldwide. (shrink)

This paper aims to search the question ‘whether the ethical issues of infectious disease, which has been so long considered as a problem in the discipline of bioethics, can be brought under the purview of public health ethics’. To explore the problem I begin with a brief description of the evolution of bioethics. I elaborate the six reasons of neglecting the discussion of infectious diseases in early bioethics as highlighted by Selgelid (2005). Then I analyse the view of Bayer (...) and Fairchild (2004) that how infectious diseases by its own ethical questions, make the shift from the autonomy-centred bioethics to common welfare focused public health ethics. However, I would like to conclude that although the ethical discussion of infectious diseases makes a moral shift from the discipline of bioethics to public health ethics, the latter should not always be solely guided by the principle of beneficence to avoid harm for the sake of community welfare. Public health ethics needs to be guided by the balance of the four biomedical principals, such as beneficence, nonmaleficence, autonomy, and justice. (shrink)

This paper examines some ethical issues arising from whole-genome association studies for multigenic diseases, focusing on the case of autism. Events occurring following the announcement of a genetic test for autism in France (2005–2009) are described to exemplify the ethical controversies that can arise when genetic testing for autism is applied prematurely and inappropriately promoted by biotech companies. The authors argue that genetic tests assessing one or a few genes involved in highly multigenic disorders can only be useful if: (...) (1) the genetic linkage found in the scientific study must be statistically convincing, reproducible and also applicable to the population to which the individual considered belongs (scientific validity); (2) the relative risk conferred by the ‘high-risk’ allele should be high enough to be significant to the patient (significant impact); (3) use of the test should lead to some improvement of outcome for the patient, resulting from adapted treatment if available, or at least from adjustment of lifestyle (or life goals) prompted by the new knowledge generated (clinical utility). Decisions concerning genetic testing for autism involve scientific judgement, value judgement and good knowledge of a constantly evolving therapeutic environment. The implementation of genetic tests for highly multigenic diseases thus requires strong mechanisms to ensure that they are used in a fashion that can benefit patients, and these mechanisms must be able to cope with rapid progress in scientific knowledge and therapeutic intervention.

In this paper, we study a stochastic epidemic model with double epidemics which includes white noise and telegraph noise modeled by Markovian switching. Sufficient conditions for the extinction and persistence of the diseases are established. In the end, some numerical simulations are presented to demonstrate our analytical results.

"The largest Ebola outbreak to date—first detected in December 2013 and still ongoing as of April 2015—has cast new light on the shortfalls of international public health systems.1 As in previous health crises, scrutiny has reemerged over the pharmaceutical industry’s ability and willingness to innovate new medicines for underserved disease areas. The public debate has intensified following revelations that promising drug candidates to treat Ebola had gone undeveloped despite compelling preclinical results.2 This lack of development is especially troubling because it (...) occurred after a recently implemented U.S. incentive scheme—the Food and Drug Administration’s (FDA) tropical disease priority review voucher program—designed to counteract exactly this problem. Taking Ebola as a case in point, it is useful to examine the short history and ongoing refinement of this voucher program, since it represents one of the most significant legislative efforts to systematically address the relative absence of com- mercial rewards for drugs targeting tropical diseases. This analysis evaluates the voucher program’s effectiveness for both stimulating private sector innovation and achieving positive health impacts among populations most severely burdened by tropical diseases. It then proposes specific recommendations for how law- makers can improve the program’s legislation to better achieve these objectives. ". (shrink)

In 2004 a survey was conducted in the member states of the European Union designed to gain greater insight into the views on control strategies for foot and mouth disease, classical swine fever, and avian influenza with respect to the epidemiological, economic and social-ethical consequences of each of these animal diseases. This article presents the results of the social-ethical survey. A selection of stakeholders from each member state was asked to prioritize issues for the prevention and control of these (...) diseases. A majority of stakeholders chose preventive measures as the preferred issue. An analysis was done to determine whether there were differences in views expressed by stakeholders from member states with a history of recent epidemics and ones without such a history, and whether there were regional differences. There were no differences between member states with or without a history of recent epidemics. There were indeed regional differences between the priority orders from Northern and Southern Europe on the one hand, and from Eastern Europe on the other. (shrink)

ArgumentThis article analyzes for the first time the earliest western maps of diseases in China spanning fifty years from the late 1870s to the end of the 1920s. The 24 featured disease maps present a visual history of the major transformations in modern medicine from medical geography to laboratory medicine wrought on Chinese soil. These medical transformations occurred within new political formations from the Qing dynasty (1644–1911) to colonialism in East Asia (Hong Kong, Taiwan, Manchuria, Korea) and hypercolonialism within (...) China (Tianjin, Shanghai, Amoy) as well as the new Republican Chinese nation state (1912–49). As a subgenre of persuasive graphics, physicians marshaled disease maps for various rhetorical functions within these different political contexts. Disease maps in China changed from being mostly analytical tools to functioning as tools of empire, national sovereignty, and public health propaganda legitimating new medical concepts, public health interventions, and political structures governing over human and non-human populations.

Many countries in Africa, and more generally those in the Global South with tropical areas, are plagued by illnesses that the wealthier parts of the world (mainly ‘the West’) neither suffer from nor put systematic effort into preventing, treating or curing. What does an ethic with a recognizably African pedigree entail for the ways various agents ought to respond to such diseases? As many readers will know, a characteristically African ethic prescribes weighty duties to aid on the part of (...) those in a position to do so, and it therefore entails that there should have been much more contribution from the Western, ‘developed’ world. However, what else does it prescribe, say, on the part of sub-Saharan governments and the African Union, and are they in fact doing it? I particularly seek to answer these questions here, by using the 2013-16 Ebola crisis in West Africa to illustrate what should have happened but what by and large did not. (shrink)

BackgroundThis study aimed to translate the negative and positive items of the Psychological Consequences Questionnaire into German, to adapt this version to the context of screening for cirrhosis and fibrosis of the liver, and to test its psychometric properties.Materials and methodsThe three subscales were translated into German using a forward-backward translation method. Furthermore, we adapted the wording to the context of liver diseases. In sum, the PCQ comprises twelve negative items and ten positive items. We tested the acceptability, distribution (...) properties, internal consistency, scale structure, and the convergent validity using an analysis sample of 443 patients who were screened for cirrhosis or fibrosis of the liver.ResultsWe found low non-response and non-unique answer rates on the PCQ items in general. However, positive items had higher non-response rates. All items showed strong floor effects. McDonald’s Omega was high for both the negative and the positive PCQ scale, as well as for the total PCQ scale. Confirmatory factor analysis could reproduce the three dimensions that the PCQ intends to measure. However, it suggests not summing up a total PCQ score and instead treat the subscales separately considering a higher order overall construct. Convergent validity with the short form of the Spielberger State-Trait Anxiety Inventory was acceptable.ConclusionOverall, our study results report a successful adaptation of the German PCQ with good performance in terms of acceptability, internal consistency, scale structure, and convergent validity. Floor-effects limit the content validity of the PCQ, which needs to be addressed in future research. However, the German version of the PCQ is a useful measurement for both negative and positive screening consequences - even in a non-cancer setting. (shrink)

In October 2015 the UK enacted legislation to permit the clinical use of two cutting edge germline-altering, IVF-based embryonic techniques: pronuclear transfer and maternal spindle transfer. The aim is to use these techniques to prevent the maternal transmission of serious mitochondrial diseases. Major claims have been made about the quality of the debates that preceded this legislation and the significance of those debates for UK decision-making on other biotechnologies, as well as for other countries considering similar legislation. In this (...) article we conduct a systematic analysis of those UK debates and suggest that claims about their quality are over-stated. We identify, and analyse in detail, ten areas where greater clarity, depth and nuance would have produced sharper understandings of the contributions, limitations and wider social impacts of these mitochondrial interventions. We explore the implications of these additional considerations for the protection of all parties involved, should the techniques transfer to clinical applications; the legitimacy of focussing on short-term gains for individuals over public health considerations, and the maintenance and improvement of public trust in medical biotechnologies. We conclude that a more measured evaluation of the content and quality of the UK debates is important and timely: such a critique provides a clearer understanding of the possible, but specific, contributions of these interventions, both in the UK and elsewhere; also, these additional insights can now inform the emerging processes of implementation, regulation and practice of mitochondrial interventions.

This case for discussion highlights some of the ethical difficulties that may arise in the use of molecular typing techniques in the control of infectious diseases. Molecular typing techniques offer evidence (stronger than regular epidemiological exploration of sources and contacts) for claims about infection routes. Such evidence will mean that public health authorities need to think about how to respond ethically to causal responsibility for contagion. In this context, questions are raised about the use of molecular typing methods for (...) source and contact tracing in the control of infectious diseases. (shrink)

The article addresses the role of scarcity in negotiating the relationship between intellectual property, particularly from a legal-economic perspective, and property rights, as understood by transaction cost economics, to shed light on the deadlock faced by those suffering from neglected tropical diseases (NTDs). The consistency of the law and economics fundamentals that support the trade on knowledge goods, namely patents on essential medicines, is put under check by Scott Veitch’s scholarship on legal irresponsibility. The damages that emerge from the (...) operations of the intellectual property system are registered in the novel concept of negative public domain, and are due mainly to the lack of access to treatments that end up being unaffordable, or to innovation that leads to new drugs that is not sufficiently incentivised though price signals. The accountability for such damages is taken into consideration by arguing that the disavowal of responsibility is made possible by the negative public domain, which is balanced by the construction of a positive response through the language of rights. As such, responsibility per se is preserved, evading one instantiation of Teubner’s legal paradoxes, but rendered ineffective by design. In other words, even if the harms endured by those affected by the NTDs can be traced back to the operations of the intellectual property system, there is no one to hold accountable. The main goal pursued through the article is to make such an arrangement explicit, by giving centrality to the notion of scarcity and its interplay between legal and economic theory, alongside the novel concept of negative public domain as a site where the actual consequences of irresponsibility lie, to hopefully inform further critique in subsequent works.

Central African highland farmers' perceptions of common bean disease were investigated using both phytopathology and anthropological techniques. Farmers rarely mentioned diseases as production constraints in formal questionnaires. More participatory research showed farmers often related disease symptoms to the effects of rain and soil depletion for fungal diseases, or to varietal traits for bean common mosaic virus. Rain or moisture is divided into numerous forms through which it can damage plants, both physically and through putrefaction. Most conditions associated with (...) putrefaction appear to be linked to pathogens. Farmers have an understanding of plant health closely related to their concept of human health. In plants, this understanding is based on the prior state of plant health. Conceptually, local disease management strategies are based on prevention by managing the conditions that promote good plant health rather than by treating disease symptoms. Intervention strategies that build on local knowledge are encouraged. (shrink)

Many experts have warned that environmental degradation is increasing the likelihood of future pandemics like COVID-19, as habitat loss and poaching increase close contact between wildlife and people. This fact has been framed as a reason to increase wildlife conservation efforts. We have many good reasons to step up conservation efforts, but arguments for doing so on the basis of pandemic prevention are rhetorically, ethically, and empricially flawed.

This paper examines the characteristics of infectious diseases that raise special medical and social ethical issues, and explores ways of integrating both current bioethical and classical public health ethics concerns. Many of the ethical issues raised by infectious diseases are related to these diseases’ powerful ability to engender fear in individuals and panic in populations. We address the association of some infectious diseases with high morbidity and mortality rates, the sense that infectious diseases are caused (...) by invasion or attack on humans by foreign micro‐organisms, the acute onset and rapid course of many infectious diseases, and, in particular, the communicability of infectious diseases. The individual fear and community panic associated with infectious diseases often leads to rapid, emotionally driven decision making about public health policies needed to protect the community that may be in conflict with current bioethical principles regarding the care of individual patients. The discussion includes recent examples where dialogue between public health practitioners and medical‐ethicists has helped resolve ethical issues that require us to consider the infected patient as both a victim with individual needs and rights and as a potential vector of disease that is of concern to the community.

Background: Arthritis is very common but is not well understood. Actually, “arthritis” is not a single disease; it is an informal way of referring to joint pain or joint disease. There are more than 100 different types of arthritis and related conditions. People of all ages, sexes and races can and do have arthritis, and it is the leading cause of disability in America. More than 50 million adults and 300,000 children have some type of arthritis. It is most common (...) among women and occurs more frequently as people get older. Common arthritis joint symptoms include swelling, pain, stiffness and decreased range of motion. Symptoms may come and go. They can be mild, moderate or severe. They may stay about the same for years, but may progress or get worse over time. Severe arthritis can result in chronic pain, inability to do daily activities and make it difficult to walk or climb stairs. Arthritis can cause permanent joint changes. These changes may be visible, such as knobby finger joints, but often the damage can only be seen on X-ray. Some types of arthritis also affect the heart, eyes, lungs, kidneys and skin as well as the joints. Objectives: The main goal of this expert system is to get the appropriate diagnosis of disease and the correct treatment and give the appropriate method of treatment through several tips that concern the disease and how to treat it and we will see it through the application on the expert system. Methods: in this paper the design of the proposed Expert System which was produced to help Orthopedist in diagnosing Arthritis disease through its symptoms such as: pain on pressure in a joint , Inflammation indicated by joint swelling, Stiffness especially in the morning , Loss of flexibility of joint, Limited, joint movement, Deformity of the joints , Weight loss and fatigue , Non-specific fever and Crepitus. The proposed expert system presents an overview about Arthritis disease is given, the cause of diseases is outlined and the treatment of disease whenever possible is given out. SL5 Object Expert System language was used for designing and implementing the proposed expert system. Results: The proposed Arthritis disease diagnosis expert system was evaluated by Orthopedics students and they were satisfied with its performance. Conclusions: The Proposed expert system is very useful for Orthopedist, patients with arthritis and newly graduated Orthopedics students. (shrink)

This paper deals with the question of how to price drugs for tropical diseases. The thesis defended in the paper is: (i) there should be no legal constraints on the profits pharmaceutical companies can make on their products for tropical diseases. In essence, (i) expresses the idea that drugs for tropical diseases should be treated as any other product on the free market and that the producers of these drugs should be allowed to sell their products at (...) whatever price the market can bear. The main argument in favour of (i) is first outlined. Five common arguments against (i) are thereafter discussed, and it is argued that all of these fail in their intended purpose. (shrink)

How is a disease contracted, and how does it progress through the body? Answers to these questions are fundamental to understanding both basic biology and medicine. Advances in the biomedical sciences continue to provide more tools to address these fundamental questions and to uncover questions that have not been thought of before. Despite these major advances, we are still facing conceptual and technical challenges when learning about the etiology of disease, especially for genetic diseases. In this review, we illustrate (...) this point by discussing the causal links between molecular mechanisms and systems-level phenotypes in molecular diseases. We begin with an examination of sickle cell anemia, and how mechanisms of the disease have been comprehended over the last century. While sickle cell anemia involves a mutation in a single protein in a single cell type, other diseases involve mutations in networks with many protein interactions and in diverse cell types. We introduce the challenges that result from these differences and illustrate the current obstacles by discussing the RASopathies, a recently discovered class of developmental syndromes that result from mutations in signaling networks. Methods to study mutant genotypes that lead to mutant phenotypes are discussed, particularly the use of model organisms and mutant proteins to study protein interactions that may be important for development of disease. These studies will point toward the future of diagnosing and treating genetic disease. (shrink)

Pandemic plans recommend phases of response to an emergent infectious disease outbreak, and are primarily aimed at preventing and mitigating human-to-human transmission. These plans carry presumptive weight and are increasingly being operationalized at the national, regional and international level with the support of the World Health Organization. The conventional focus of pandemic preparedness for EIDs of zoonotic origin has been on public health and human welfare. However, this focus on human populations has resulted in strategically important disciplinary silos. As the (...) risks of zoonotic diseases have implications that reach across many domains outside traditional public health, including anthropological, environmental, and veterinary fora, a more inclusive ecological perspective is paramount for an effective response to future outbreaks.

Anthropogenic climate change is causing temperature rise in temperate zones resulting in climate conditions more similar to subtropical zones. As a result, rising temperatures increase the range of disease-carrying insects to new areas outside of subtropical zones, and increased precipitation causes flooding that is more hospitable for vector breeding. State governments, the federal government, and governmental agencies, like the Animal and Plant Health Inspection Service of USDA and the National Notifiable Disease Surveillance System of the U.S. Centers for Disease Control (...) and Prevention, lack a coordinated plan for vector-borne disease accompanying climate change. APHIS focuses its surveillance primarily on the effect of illness on agricultural production, while NNDSS focuses on the emergence of pathogens affecting human health. This article provides an analysis of the current framework of surveillance of, and response to, vector-borne infectious diseases, the impacts of climate change on the spread of vector-borne infectious diseases, and recommends changes to federal law to address these threats.

Mandatory reporting of infectious diseases (MRID) is an essential practice to prevent disease outbreaks. Disease notification is a mandatory procedure for most infectious diseases, even during non-pandemic periods in healthcare. The main rationale behind MRID is the protection of public health. The information and data provided by infectious disease reports are used for many purposes, such as preventing the spread and potential negative impact of infectious diseases, assessing the national and global situation regarding reported diseases, conducting (...) scientific research and planning health policy. In this context, the relevant information benefits public health, health systems and scientific work. Additionally, the follow up and treatment of individuals with infectious diseases is a necessity in certain cases to protect those who cohabit with them. However, these benefits cannot be accepted as unrestricted justifications for MRID, since it is evident that reporting should be conducted within ethical and legal boundaries. MRID should only be devised and implemented with due regard to balancing potential benefits between all individuals, as well as between the individual and the rest of society. Disease notification systems that are not designed with a balancing and harm-reductionist approach may lead to stigmatisation and discrimination. This study aims to investigate the legal framework and ethical issues regarding the reporting of individuals diagnosed with COVID-19 in Turkey—which is a primary example of a developing country.

Inflammatory immune cells, when activated, display much the same metabolic profile as a glycolytic tumor cell. This involves a shift in metabolism away from oxidative phosphorylation towards aerobic glycolysis, a phenomenon known as the Warburg effect. The result of this change in macrophages is to rapidly provide ATP and metabolic intermediates for the biosynthesis of immune and inflammatory proteins. In addition, a rise in certain tricarboxylic acid cycle intermediates occurs notably in citrate for lipid biosynthesis, and succinate, which activates the (...) transcription factor Hypoxia‐inducible factor. In this review we take a look at the emerging evidence for a role for the Warburg effect in the immune and inflammatory responses. The reprogramming of metabolic pathways in macrophages, dendritic cells, and T cells could have relevance in the pathogenesis of inflammatory and metabolic diseases and might provide novel therapeutic strategies.

The COVID-19 pandemic forced us to reconsider our interactions with the world around us, shifting how we navigate public and private spaces every day. Most people in the United States previously thought nothing of touching railings or doorknobs, going to school or work while ill, or attending crowded events. Along with new health interventions and institutional practices, daily behaviors aimed at infection control, such as routine hand washing and wearing face masks when symptomatic, protected our communities from COVID-19. Many new (...) interventions and practices are here to stay, but it is unclear which personal behaviors to protect against COVID-19 and other infectious diseases we should continue. Intuitively plausible ethical arguments support individuals taking reasonable measures to avoid causing or propagating harm to other members of the community. As such, by failing to adopt easily implementable preventive behaviors, we live ethically suboptimal lives and violate our social contract to one another. As the world transitions from epidemic to endemic COVID-19, applying the lessons learned from the pandemic is crucial to mitigating old and new infectious disease threats. Along with the role of public health agencies to organize and communicate about communicable diseases, clinicians and public health workers have critical roles in establishing social norms for behaviors that prevent the spread of infectious diseases, given their professional responsibilities and statuses as trusted authority figures.
