The past two decades have seen a dramatic growth in the use of statisticians and economists for the presentation of expert testimony in legal proceedings. In this paper, we describe a hypothetical case modeled on real ones and involving statistical testimony regarding the causal effect of lead on lowering the IQs of children who ingest lead paint chips. The data we use come from a well-known pioneering study on the topic and the analyses we describe as the expert testimony are (...) similar to ones that can be found in major scientific journals. The battle of the experts in this hypothetical case resembles that which many encounter as expert witnesses. The paper concludes with some observations and advice. (shrink)

Applying a medical conception of toxicity to speech practices, this paper calls for an epidemiology of discursive toxicity. Toxicity highlights the mechanisms by which speech acts and discursive practices can inflict harm, making sense of claims about harms arising from speech devoid of slurs, epithets, or a narrower class I call ‘deeply derogatory terms.’ Further, it highlights the role of uptake and susceptibility, and so suggests a framework for thinking about damage variation. Toxic effects vary depending on one’s (...) epistemic position, access, and authority. An inferentialist account of discursive practice plus a dynamic view of the power of language games offers tools to analyze the toxic power of speech acts. A simple account of language games helps track changes in our discursive practices. Identifying patterns contributes to an epidemiology of toxic speech, which might include tracking increasing use of derogatory terms, us/them dichotomization, terms of isolation, new essentialisms, and more. Using this framework, I analyze some examples of speech already said to be toxic, working with a rough concept of toxicity as poison. Finally, exploring discursive toxicity pushes us to find ways that certain discursive practices might “inoculate” one to absorbing toxic messages, or less metaphorically, block one’s capacity to make toxic inferences, take deontic stances that foster toxicity, etc. (shrink)

Medical and public health professionals recommend wearing face masks to combat the spread of the coronavirus disease of 2019. While the majority of people in the United States support wearing face masks as an effective tool to combat COVID-19, a smaller percentage declared the recommendation by public health agencies as a government imposition and an infringement on personal liberty. Social media play a significant role in amplifying public health issues, whereby a minority against the imposition can speak loudly, perhaps using (...) tactics of verbal aggression taking the form of toxic language. We investigated the role that toxicity plays in the online discourse around wearing face masks. Overall, we found tweets including anti-mask hashtags were significantly more likely to use toxic language, while tweets with pro-mask hashtags were somewhat less toxic with the exception of #WearADamnMask. We conclude that the tensions between these two positions raise doubt and uncertainty around the issue, which make it difficult for health communicators to break through the clutter in order to combat the infodemic. Public health agencies and other governmental institutions should monitor toxicity trends on social media in order to better ascertain prevailing sentiment toward their recommendations and then apply these data-driven insights to refine and adapt their risk communication messaging toward mask wearing, vaccine uptake, and other interventions.

On November 28, 2009, as part of events marking the twenty-fifth anniversary of the disaster at the Union Carbide plant in Bhopal, gas survivors protested the contents of the report prepared by government scientists that mocked their complaints about contamination. The survivors shifted from the scientific document to a mediated lunch invitation performance, purporting to serve the same chemicals as food that the report had categorized as having no toxic effects. I argue that the lunch spread, consisting of (...) soil and water from the pesticide plant, explicitly front-staged and highlighted the survivor’s forced intimate relationship with such chemicals, in order to reshape public perception of risks from toxins. Chemical matter like sevin tar and naphthol tar bound politicians, scientists, corporations, affected communities, and activists together, as these stakeholders debated the potential effects of toxic substances. This gave rise to an issue-based “chemical public.” Borrowing from such theoretical concepts as “ontologically heterogeneous publics” and “agential realism,” I track the existing and emerging publics related to the disaster and the campaigns led by the International Campaign for Justice in Bhopal advocacy group.

The financial toxicity of biotherapeutic treatments is examined. Kymriah, a new gene therapy, has a list price of $475,000 per treatment; Yescarta, from Kite Pharma, costs $373,000 per treatment. Such costs are a significant burden on patients, patients’ families, payers, health care systems, and communities. Studies have shown that financial toxicity—the effect of excessive treatment cost—diminishes patients’ quality of life, compliance, and survival. Some pharmaceutical companies promote outcomes-based pricing and other strategies to offset financial toxicity, but these approaches have not (...) been shown to reduce burdens. Catholic teaching holds that the benefits of treatment should outweigh its burdens, and that burdensome treatments are not obligatory. The financial toxicity of treatments should be included in the ethical assessment of burdens on the patient. (shrink)

Sodium monofluoroacetate (1080) is a mammalian pesticide used in different parts of the world for the control of mammalian pest species. In New Zealand it is used extensively and very successfully as a conservation management tool for the control of brushtail possums (Trichosurus vulpecula) – an introduced marsupial that has become a substantial agricultural and conservation management pest. Possums pose a threat to cattle farming in New Zealand as they are a vector for bovine tuberculosis. In protected natural areas, possum (...) browsing is responsible for large scale defoliation of native vegetation. As with many other pesticides, there has been some degree of popular concern about the use of this toxin and its safety, with particular reference to non-target effects. These concerns have been associated with potential non-target effects on human health, and the health of animals of recreational value (e.g., hunting dogs and game animals). This has led to the development of a strong “anti-1080” lobby in New Zealand. In contrast, this study encompasses a science-based risk analysis focusing on the potential risks to non-target native wildlife with a particular focus on chronic toxicity. It finds that there is evidence that 1080 may have endocrine disrupting capabilities (with potential relevance for non-target wildlife) but that this still needs more detailed investigation. This can be clarified by further targeted research. Further research is also needed to test the degradation rates of 1080 and its breakdown products at ecologically-relevant temperatures (i.e., winter stream temperatures – below 11 °C). Such research may demonstrate that some adjustment to 1080 risk management is warranted in New Zealand, or it may help to put to rest the current controversy over the use of this cost effective conservation management tool.

We present a novel model of individual people, online posts, and media platforms to explain the online spread of epistemically toxic content such as fake news and suggest possible responses. We argue that a combination of technical features, such as the algorithmically curated feed structure, and social features, such as the absence of stable social-epistemic norms of posting and sharing in social media, is largely responsible for the unchecked spread of epistemically toxic content online. Sharing constitutes a distinctive (...) communicative act, governed by a dedicated norm and motivated to a large extent by social identity maintenance. But confusion about this norm and its lack of inherent epistemic checks lead readers to misunderstand posts, attribute excess or insufficient credibility to posts, and allow posters to evade epistemic accountability—all contributing to the spread of epistemically toxic content online. This spread can be effectively addressed if people and platforms add significantly more context to shared posts and platforms nudge people to develop and follow recognized epistemic norms of posting and sharing.

An increasing number of drugs removed from the market because of unacceptable toxicity raises concerns regarding preapproval testing of drug safety. In the present paper it is postulated that the non-inferiority type of trial should be abandoned in favor of the superiority trial with active controls and less stringent (p<0.1, both for efficacy and toxicity) statistics. This approach will increase sensitivity of detection of drug-induced adverse effects at the expense of increasing false positive results regarding the difference in efficacy (...) between the tested and reference drug. Such a move will increase the protection of future patients. In addition, the proposed design is far more acceptable from the clinical (e.g. no need to specify the statistically expected “unimportant” number of deaths) and ethical points of view, as well as being favored by the strong incentive of involved parties. In the second part of this paper arguments are presented in favor of the hypothesis that placebo (still used in some superiority trials) does not induce adverse effects. The assertion that placebo may induce adverse effects is probably biased by the nature of the clinical experiment. Such a conclusion is supported by studies indicating that placebo-induced adverse effects are disease — and treatment — specific. The modification of clinical trials according to the proposed changes may increase the trials’ sensitivity at detecting adverse effects of drugs. (shrink)

In 2008, Susan L. Smith published “Mustard Gas and American Race-Based Human Experimentation in World War II.” Research, undertaken by the US Army, attempted to quantify the effect of mustard gas and othe chemical agents on people from different racial groups. This was based on the idea that different races would respond differently to the toxins, and in particular that this would be evident through dermal reaction. In other words, different skin color might mean different skin constitution. Some of the (...) testing seemed reasonable, since new chemicals and equipment had been developed since 1919, and the racial issue added another dimension to the research. On closer examination, the testing was primarily based on old chemical agents such as mustard gas, Lewisite and phosgene, and thus the extent of the testing seemed scientifically and medically unnecessary. The chemical agents had been developed, tested, used in battle, the wounded treated and the dead subjected to detailed pathological study. The major combatants in World War I had all committed extensive scientific resources to the study of these agents looking at both offensive and defensive aspects of their use, including toxicity testing. The U.S. Chemical Warfare Service had been formed in 1918 to specifically deal with issues such as toxicity tests, so why was the U.S. Army revisiting the subject of chemical weapons testing during World War II?

This manuscript reviews recent evidence supporting the utility of telomeres and mitochondrial DNA copy number (mtDNAcn) in detecting the biological impacts of adverse childhood experiences (ACEs) and outlines mechanisms that may mediate the connection between early stress and poor physical and mental health. Critical to interrupting the health sequelae of ACEs such as abuse, neglect, and neighborhood disorder, is the discovery of biomarkers of risk and resilience. The molecular markers of chronic stress exposure, telomere length and mtDNAcn, represent critical biological (...) links between ACEs and poor health outcomes. We examine how telomeres and mtDNAcn may exacerbate health disparities and contribute to the intergenerational transmission of trauma. Finally, we explore how these molecular markers of early stress exposure may help define the role of resilience and develop effective interventions to moderate ACE health risk impact. (shrink)

Over the past several decades, urban community gardens have arisen in diverse and economically compromised neighborhoods across the U.S. as part of multiple environmental justice efforts. Urban community gardens have enabled users to mitigate the effects of many environmental injustices such as the impact of food deserts, nutrient poor food found at convenience stores, and pesticide laden grocery items. While these benefits have promulgated across the U.S., community gardens are also well known to be located in historically contaminated locations (...) in urban landscapes. These landscapes include former brownfield sites, superfund sites, and other abandoned spaces of contamination. Although environmental justice efforts to reclaim healthy food in urban community gardens are commendable, the presence and effects of potentially harmful contaminants is often overlooked as gardens are established. Further, governmental organizations tasked with protecting human health, such as the Environmental Protection Agency, have not established any health standards for urban community gardens. This creates many challenges in determining what is safe in community gardens, and garden mangers and users are often unaware of how severe the impacts of contamination may be or how to mitigate its effects. In this study, I highlight the prevalence of harmful concentrations of contaminants in urban community gardens in and near Seattle, Washington that are managed with organic practices. I then present the challenges and barriers to gardening in contaminated spaces. Finally, I make recommendations to address contamination in gardens spaces, and call for better regulatory standards and other forms of support to mitigate risk to users. (shrink)

Parkinson's disease (PD) is generally sporadic but a number of genetic diseases have parkinsonism as a clinical feature. Two dominant genes, α‐synuclein (SNCA) and leucine‐rich repeat kinase 2 (LRRK2), are important for understanding inherited and sporadic PD. SNCA is a major component of pathologic inclusions termed Lewy bodies found in PD. LRRK2 is found in a significant proportion of PD cases. These two proteins may be linked as most LRRK2 PD cases have SNCA‐positive Lewy bodies. Mutations in both proteins are (...) associated with toxic effects in model systems although mechanisms are unclear. LRRK2 is an intracellular signaling protein possessing both GTPase and kinase activities that may contribute to pathogenicity. A third protein, tau, is implicated as a risk factor for PD. We discuss the potential relationship between these genes and suggest a model for PD pathogenesis where LRRK2 is upstream of pathogenic effects through SNCA, tau, or both proteins. (shrink)

Many legal disputes turn on scientific, especially statistical, evidence. Traditionally scientists have accepted only that statistical evidence which satisfies a 95 percent (or 99 percent) rule — that is, only evidence which has less than five percent (or one percent) probability of resulting from chance.The rationale for this rule is the reluctance of scientists to accept anything less than the best-supported new knowledge. The rule reflects the internal needs of scientific practice. However, when uncritically adopted as a rule for admitting (...) legal evidence, the seemingly innocuous 95 percent rule distorts the balance of interests historically protected by the legal system. In particular, plaintiffs in toxic tort and employment discrimination suits are effectively held to a heavier burden of proof in showing that their injuries were more probably than not caused by the defendant's actions. The result is that too many victims of toxic torts or employment discrimination cannot win legal redress for their injuries. (shrink)

Transgenic insecticidal Bt crops are being increasingly used worldwide, and concern is increasing about resistance and their effects on nontarget organisms. The toxin acts as a weak pesticide and, hence, the effects are subtler than those of chemical biocides. However, the toxin is ever present, but concentrations vary with age of plant and plant subunit, causing varying lethal and sublethal effects on pest survival, developmental time, and fecundity. Refuges for susceptibility to Bt occur spatially in non-Bt hosts (...) and temporally within the crop because of time-varying toxicity and pest tolerance. Natural enemies feeding on Bt-intoxicated prey may have reduced longevity and, likely, fecundity that reduces their efficacy in controlling pest populations, and pest resurgence and secondary pest outbreaks may occur that may require insecticide use. System modeling is proposed as an efficient tool for examining the use of extant and future biotechnologies in pest control. (shrink)

The purpose of this article is to understand how historical oppression has undermined health through environmental injustices that have given rise to food insecurity. Specifically, the article examines ways in which settler colonialism has transformed and contaminated the land itself, impacting the availability and quality of food and the overall health of Indigenous peoples. Food security and environmental justice for Gulf Coast, state-recognized tribes has been infrequently explored. These tribes lack federal recognition and have limited access to recourse and supplemental (...) resources as a result. This research fills an important gap in the literature through exploring the intersection of environmental justice and food insecurity issues for this population. Partnering with a community-advisory board and using a qualitative descriptive methodology, 31 Gulf Coast Indigenous women participated in semi-structured interviews about their healthcare experiences and concerns. Through these interviews, participants expressed concerns about (a) the environmental impacts of pollution on the contamination of food and on the health of tribal members; and (b) the impact of these changes on the land, such as negatively impacting gardening practices. The authors of this study document how environmental changes have compounded these concerns and contribute to the overall pollution of food and water sources and unviability of subsistence practices, severely effecting tribal members’ health. In conclusion, we show how social and environmental justice issues such as pollution, industry exploitation, and climate change perpetuate the goals of settler colonialism through undermining cultural practices and the overall health of Indigenous peoples.

ABSTRACTThis essay introduces the notion of a literary clinical practice for which it remains essential to continue to consider those texts that open up a place for a readership, or audience, or even a civilization to consider the endlessly generative failure of its literature to write mental health. Concerned with mental illness that is an effect of language on the subject, the body, and of the enigma of the truth as cause, psychoanalysis is the crucial interlocutor for any literary clinical (...) concern with the maladies of literature and society. In order to re-assess the utility of Shakespeare’s Hamlet to contemporary problems such as depression – perhaps the dominant symptom of our time – this essay attempts a reconsideration of Jacques Lacan’s famous seminar on Hamlet from the perspective of the contemporary clinic of the Lacanian orientation in psychoanalysis led by Jacques-Alain Miller.

Lead (Pb) contamination of the environment is an important human health problem. Children are vulnerable to Pb toxicity; it causes damage to the central nervous system and, in some extreme cases, can cause death. Lead is widespread, especially in the urban environment, and is present in the atmosphere, soil, water and food. Pb tends to accumulate in surface soil because of its low solubility, mobility, and relative freedom from microbial degradation of this element in the soil. Lead is present in (...) soil as a result to weathering and other pedogenic processes acting on the soil parent material; or from pollution arising caused by the anthropogenic activities; such as mining, smelting and waste disposal; or through the adoption of the unsafe and unethical agricultural practices such as using of sewage sludge, and waste water in production of vegetable crops or cultivation of vegetables near highways and industry regions. Lead concentrations are generally higher in the leafy vegetables than the other vegetables. Factors affecting lead uptake included its concentration in the soil, soil pH, soil type, organic matter content, plant species, and unsafe agriculture practices. Generally, as Pb concentration increased; dry matter yields of roots, stems and leaves as well as total yield decreased. The mechanism of growth inhibition by lead involve: a decrease in number of dividing cells, a reduction on chlorophyll synthesis, induced water stress to plants, and decreased NO 3 - uptake, reduced nitrate and nitrite reductase activity, a direct effect of lead on protein synthesis, a decrease on the uptake and concentration of nutrients in plants. The strategies to minimize Pb hazard can be represented in: (a) Phytoremediation, through natural plants are able to bio-accumulate Pb in their above–ground parts, which are then harvested for removal such as, using Indian Mustard (Brassica juncea), Ragweed (Ambrosia artemisiifolia), Hemp Dogbane (Apocynum cannabium), or Poplar trees, which sequester lead in its biomass. (b) Good and ethical agricultural practices such as cultivation of vegetables crops as far from busy streets or highways and industry regions as well as nonuse of sewage sludge and waste water in cultivated soils. (c) Increasing the absorptive capacity of the soil by adding organic matter and humic acid. (d) Growing vegetable crops and cultivars with a low potential to accumulate lead, especially in soils exposed to atmospheric pollution. (e) Washing of leafy vegetables by water containing 1 % vinegar or peeling roots, tubers, and some fruits of vegetables before consumption may be an important factor in reducing the lead concentration.

Arbuscular mycorrhizal fungi are considered as a potential biotechnological tool for improving phytostabilization efficiency and plant tolerance to heavy metal-contaminated soils. However, the mechanisms through which AMF help to alleviate metal toxicity in plants are still poorly understood. A greenhouse experiment was conducted to evaluate the effects of two AMF species on the growth, Pb accumulation, photosynthesis and antioxidant enzyme activities of a leguminous tree at Pb addition levels of 0, 500, 1000 and 2000 mg kg-1 soil. AMF symbiosis (...) decreased Pb concentrations in the leaves and promoted the accumulation of biomass as well as photosynthetic pigment contents. Mycorrhizal plants had higher gas exchange capacity, non-photochemistry efficiency, and photochemistry efficiency compared with non-mycorrhizal plants. The enzymatic activities of superoxide dismutase, ascorbate peroxidases and glutathione peroxidase were enhanced, and hydrogen peroxide and malondialdehyde contents were reduced in mycorrhizal plants. These findings suggested that AMF symbiosis could protect plants by alleviating cellular oxidative damage in response to Pb stress. Furthermore, mycorrhizal dependency on plants increased with increasing Pb stress levels, indicating that AMF inoculation likely played a more important role in plant Pb tolerance in heavily contaminated soils. Overall, both F. mosseae and R. intraradices were able to maintain efficient symbiosis with R. pseudoacacia in Pb polluted soils. AMF symbiosis can improve photosynthesis and reactive oxygen species scavenging capabilities and decrease Pb concentrations in leaves to alleviate Pb toxicity in R. pseudoacacia. Our results suggest that the application of the two AMF species associated with R. pseudoacacia could be a promising strategy for enhancing the phytostabilization efficiency of Pb contaminated soils.

This article examines a fundamental question of justice in global health. Is it ethically preferable to provide a larger number of people with cheaper treatments that are less effective (or more toxic), or to restrict treatments to a smaller group to provide a more expensive but more effective or less toxic alternative? We argue that choosing to provide less effective or more toxic interventions to a larger number of people is favored by the principles of utility, equality, (...) and priority for those worst-off. Advocates are mistaken to demand that medical care provided in low-income and middle-income countries should be the same as in high-income countries. (shrink)

We consider an ethical dilemma in global health: is it ethically acceptable to provide some patients cheaper treatments that are less effective or more toxic than the treatments other patients receive? We argue that it is ethical to consider local resource constraints when deciding what interventions to provide. The provision of cheaper, less effective health care is frequently the most effective way of promoting health and realizing the ethical values of utility, equality, and priority to the worst off.

In light of arguments that citizen science has the potential to make environmental knowledge and policy more robust and democratic, this article inquires into the factors that shape the ability of citizen science to actually influence scientists and decision makers. Using the case of community-based air toxics monitoring with ‘‘buckets,’’ it argues that citizen science’s effectiveness is significantly influenced by standards and standardized practices. It demonstrates that, on one hand, standards serve a boundary-bridging function that affords bucket monitoring data a (...) crucial measure of legitimacy among experts. On the other hand, standards simultaneously serve a boundary-policing function, allowing experts to dismiss bucket data as irrelevant to the central project of air quality assessment. The article thus calls attention to standard setting as an important site of intervention for citizen science-based efforts to democratize science and policy. (shrink)

The ideology of consumption and the imperative of consumer choice have washed across the globe. In today's developed economies there is an ever-increasing amount of buying, amidst an ever-increasing amount of purchase options, amidst an ever-increasing amount of stress, amidst an ever-decreasing amount of discretionary time. This brief essay reviews research suggesting, for example, that hyperchoice confuses people and increases regret, that hyperchoice is initially attractive but ultimately unsatisfying, and that hyperchoice is psychologically draining. Future research is then discussed, including (...) how and why hyperchoice may have other toxic effects on people, including the degrading of moral emotions and behavior. (shrink)

In the mid-1980s, social scientists compared outcome measures of related drug studies, some funded by private companies and others by nonprofit organizations or government agencies. The concept of a “funding effect” was coined when it was discovered that study outcomes could be statistically correlated with funding sources, largely in drug safety and efficacy studies. Also identified in tobacco research and chemical toxicity studies, the “funding effect” is often attributed, implicitly or explicitly, to research bias. This article discusses the meaning of (...) scientific bias in research, examines the strongest evidence for the “funding effect,” and explores the question of whether the “funding effect” is an indicator of biased research that is driven by the financial interests of the for-profit sponsor. This article argues that the “funding effect” is merely a symptom of the factors that could be responsible for outcome disparities in product assessment. Social scientists should not suspend their skepticism and choose as a default hypothesis that bias is always or typically the cause. (shrink)

The biological effects of low doses of toxic and carcinogenic chemicals are currently a matter of significant scientific controversy. This paper argues that philosophers of science can contribute to alleviating this controversy by examining it with the aid of a novel account of scientific anomaly. Specifically, analysis of contemporary research on chemical hormesis (i.e., alleged beneficial biological effects produced by low doses of substances that are harmful at higher doses) suggests that scientists may initially describe anomalous phenomena (...) in terms of multiple distinct "characterizations," each of which is compatible with current empirical evidence. By focusing attention on this feature of scientific anomalies, philosophers of science can alleviate the controversy over low-dose chemical effects in at least two ways: (1) they can pinpoint the significant ways in which particular characterizations frame the controversy, and (2) they can identify the methodological value judgments at stake in researchers' choice of characterizations.

While the benefits of nanomaterials are evident (...) there are studies which indicate the potential risk to biological systems. Substances known to be harmless in bulk can be potentially toxic in certain fibrous and nanoparticle form. Risk assessment studies with nanomaterials largely focus on mouse models. There are very few studies on their effects on aquatic species and plants which form the largest in the productivity chain with respect to the ecological pyramid. This study reviews the research done worldwide in the area of risk assessment of nanomaterials, particularly the effects on aquatic and plant systems. Risk assessment is the foundation for regulatory decision making. A general comparison of the regulatory regime in nanotechnology is performed to understand the extent of development. (shrink)

Based on fieldwork, this article highlights the unexpected effects of controversies about nanotechnology in France. These controversies stem in particular from a strong challenge to the field by civil society protests and criticism concerning environmental and health risks. One reason for this challenge is the specific difficulties in assessing the toxicity and ecotoxicity of nanomaterials. Civil society organizations have pushed for strictly controlling or stopping academic, industrial, or even basic research. They were not successful in this regard but their (...) activities prompted researchers to think about “safe by design” solutions and this led to new interdisciplinary cooperation. Furthermore, the uncertainty about the risks assessment resulted in a reconfiguration of the relationship between academic research and industrial companies. Researchers have become essential to the shaping of safe products. The risks of nanomaterials have thus been a driving force for new research and innovation practices. (shrink)

Today, one out of every six children suffers from some form of neurodevelopmental abnormality. The causes are mostly unknown. Some environmental chemicals are known to cause brain damage and many more are suspected of it, but few have been tested for such effects. Philippe Grandjean provides an authoritative and engaging analysis of how environmental hazards can damage brain development and what we can do about it. The brain's development is uniquely sensitive to toxic chemicals, and even small deficits (...) may negatively impact our academic achievements, economic success, risk of delinquency, and quality of life. Chemicals such as mercury, polychlorinated biphenyls, arsenic, and certain pesticides pose an insidious threat to the development of the next generation's brains. When chemicals in the environment affect the development of a child's brain, he or she is at risk for mental retardation, cerebral palsy, autism, ADHD, and a range of learning disabilities and other deficits that will remain for a lifetime.We can halt chemical brain drain and protect the next generation, however, and Grandjean tells us how. First, we need to control all of the 200 industrial chemicals that have already been proven to affect brain functions in adults, as their effects on the developing brain are likely even worse. We must also push for routine testing for brain toxicity, stricter regulation of chemical emissions, and more required disclosure on the part of industries who unleash hazardous chemicals into products and the environment. Decisions can still be made to protect the brains of future generations."In his crisply written, deeply documented book, Dr. Philippe Grandjean, renowned physician and public health specialist, describes the exquisite vulnerability of the developing human brain to toxic chemicals in the environment, a vulnerability that he ascribes to the brain's almost unimaginable complexity. Today, nearly one in 6 children is born with a neurodevelopmental disorder - a birth defect of the brain. One in 8 has attention deficit disorder. One in 68 is diagnosed with autism spectrum disorder. These rates are far higher than those of a generation ago, and, although they are less publicized, the problems are more prevalent than those caused by thalidomide in the 1960's. The increases are far too rapid to be genetic. They cannot be explained by better diagnosis. How then could they have come to be? Dr. Grandjean has a diagnosis -- the thousands of toxic chemicals that have been released to the environment in the past 40 years with no testing for toxicity. David P. Rall, former Director of the US National Institute of Environmental Health Sciences, once stated that 'If thalidomide had caused a ten-point loss of IQ rather than obvious birth defects of the limbs, it would probably still be on the market'. This is the core message of Dr. Grandjean's 'must read' book." - Philip J. Landrigan, Dean for Global Health, Ethel H.

The historical background of the discovery of adverse health effects of medicines, food additives, pesticides, and other chemicals is reviewed, and the development of national and international regulations and testing procedures to protect the public against the toxic effects of these drugs and chemicals is outlined. Ethical considerations of the safety evaluation of drugs and chemicals by human experimentation and animal toxicity studies, ethical problems associated with clinical trials, with the falsification of clinical and toxicological data, and (...) with inadequate experimental methodology, are reviewed, and the ethics of the marketing of drugs and their post-marketing surveillance, are similarly considered. These ethical problems are illustrated with many specific examples, including the drugs neoarsphenamine, chloramphenicol, thalidomide, diethyl stilboestrol and benoxaprofen. (shrink)

In spite of these efforts in the 1920s and 1930s to initiate ongoing research on contraception, the subject of birth control remained a problem of concern primarily to the social activist rather than to the research scientist or practicing physician.80 In the 1930s, as has been shown, American scientists turned to the study of other aspects of reproductive physiology, while American physicians, anxious to eliminate the moral and medical dangers of contraception, only reluctantly accepted birth control as falling within their (...) professional domain.As a result, the problem of cheap, effective, and safe contraception was not solved by these earliest attempts. Consideration of the subject was initiated afresh by private philanthropy after World War II, sparked by a new wave of interest in population studies.81 Summarizing such efforts to support research in the reproductive sciences, a recent Ford Foundation study has noted: “To initiate and sustain serious research in the reproductive sciences has required for more than half a century concerted effort by interested individuals and private organizations, mainly from outside the mainstreams of the biomedical research community.”82The early laboratory research on chemical contraception described in this paper was but one important outcome of the concerted effort made by reformers in the 1920s to eliminate a variety of social problems thought to derive from excessive fertility. Scientific arguments and expertise were employed to advocate reform as well as to define the appropriate solution to such social problems. Scientists were recruited as advocates for the movement, but they were also employed as researchers in laboratory investigations sponsored by these same reformers.Sponsors of these early laboratory studies noted the difficulty of obtaining first-class investigators.83 The routine analyses necessary for such research, as well as the traditional scientific aversion to applied problems, provide only a partial explanation for this response. The real difficulty lay in recruiting investigators to a field that had previously been taboo. Once opened up — first as socially relevant, and finally as scientifically sound — there was much interest in this area, and the appeal to researchers of the scientific issues surrounding fertility and reproduction soon surpassed that of the reforming value of birth control.A survey of the kinds of experimental investigations sponsored by birth control advocates indicates the range of physiological problems explored by contraceptive research. The most definitive work was done on the efficacy and safety of spermicides, but the potential of other contraceptive methods was also examined. Investigators attempted to develop spermatoxins that would effectively immunize women against sperm, and they also tried to elucidate the mechanism of hormonal control of reproduction. In fact, speculations about the possible hormonal manipulation of fertility were expressed at the Seventh International Birth Control Conference held in Zurich in 1930.84In the 1920s, clinical studies were undertaken to assess the effectiveness of the various birth control methods. Laboratory investigators complemented this work by screening spermicides for safety and testing for their ability to kill sperm. There were a variety of birth control preparations on the market, but no one really knew whether these were effective or even safe.85 Although the physiology of other major organ systems was well advanced, the scientific study of reproductive physiology and contraceptive technology was clearly in its infancy in this period. Routine analyses simply could not be conducted, because the fundamental research establishing baselines had not yet been done. Scientists used this fact to redirect attention to basic research on reproduction.Laboratory research on contraception indicated important unexplored areas for physiological investigation. Social activists, who had encouraged prominent scientists to become interested in both the social value and the genetic implications of birth control, found these investigators revising the goals of their research. The biologists had formed their own network and had begun to seek out funding, reformulating the justification for sponsorship of further investigations. The eugenic motivations underlying these studies, which had initially made them theoretically attractive to biologists, were gradually eroded. Concern with “human evolution” ceded its place to interest in physiological mechanisms. Crew and others began to note that the use of biological theory to justify essentially political decisions had serious limitations. Biologists had become uncomfortable with those very arguments which had originally captured their interest. Recognition of the potential political abuse wrought by applying scientific principles to society was expressed by Crew just one year after the Zurich meeting. Referring to previous assessments of the role of sex in reproduction, he generalized: “In the past the biologist has justified feudalism, Manchester Liberalism, socialism and every other type of social organization and political programme by reference to selected biological phenomena.”86 By 1932 Crew had also begun to question the biological logic of regulated breeding, and had made it clear to his American sponsor that there was no simple correspondence between the practice of birth control and the genetic improvement of the human race.87Biologists further began to recognize, however, that although the hopeful genetic solution to human problems was probably an illusion, contraception still remained one tangible means to alleviate, human misery. Some laboratory scientists, like Crew, acknowledged the applicability of their own particular skills to this problem. For a few brief years, social needs and scientific goals were mutually supportive and closely intertwined. But as laboratory researchers gained interest in the study of reproduction and established their own priorities in this field, they temporarily withdrew from the arena of debate over birth control as an important mechanism for social reform.With the rise of Hitler, the genetic arguments for birth control rapidly lost their appeal. But by that time the scientific problem of how to achieve effective contraception had entered the professional consciousness. Both physicians and scientists began to be aware of birth control as a subject within their domain of expertise, although outside the principal focus of their research. Scientific discussion of birth control permanently altered from a question of justification to a problem of method: How could one achieve reliable and safe contraception? This had been Sanger's and Dickinson's goal from the beginning. Laboratory scientists had indeed been persuaded to undertake this work; this research had in turn affected biologists' perceptions of the whole field of reproductive physiology, encouraging further study of reproductive mechanisms. The promise of new knowledge provided for continued funding of this research, despite the caution by scientists that the social benefits would not be as immediate or as far-reaching as advocates and they themselves had first argued.The activities of birth control activists and their supporting agencies, and the financial backing of private contributors and foundations, notably the Rockefeller philanthropies, provided an important new stimulus to the development of research on the biology of reproduction in the late 1920s and early 1930s. Biologists were able to claim an enlarged realm of issues for scientific study through their activities as advocates and as investigators for the birth control movement. At the same time, they promised as-yet-undiscovered possibilities for regulating human reproduction once its physiology was understood. The knowledge and control that they promised lay in understanding the whole reproductive cycle — not merely in evaluating the toxic effects of presumptive spermicides.Chemical spermicides never summoned the interest of scientists as the contraceptive pill was to do, yet that research did reinforce the widespread perceptions of scientific research as essential to social reform. Spermicide investigations focused research efforts in reproductive biology by challenging traditional taboos, defining problems for further study, and providing laboratory investigators the opportunity to assert the social and scientific value of their own skills. Crew echoed this attitude as he observed in 1934:Man has turned from the adventurous conquest of his environment to the conquest of himself. To-day is the day of biological invention, eagerly used for the control of the undesirable and the unwanted. Sex and reproduction are no longer hedged around by myth and taboo; they are no longer accepted as mysteries that defy understanding. They are matters inviting examination and explanation; they are regarded as expressions of physico-chemical forces, the nature of which is to be displayed. It is accepted that when knowledge is sufficient, control will be absolute, and, though knowledge is not yet sufficient, readers... must be persuaded to the view that this will not always be so.88The synergism between reproductive biology and social needs has been temporary and sporadic, but recurring, since the 1920s. Scientific research programs have clearly been influenced by issues raised by public debate. Nevertheless, reproductive biologists have continued to assert their own professional goals. For the most part, they have rejected problems without inherent scientific interest and have spurned applied research except as it has had a direct bearing on current research themes. This attitude, apparent among American and British investigators in the 1930s, created the intellectual context for the invention and acceptance of the technically sophisticated oral contraceptive pill. It did not foster the production and improvement of the simple, safe, effective, and cheap vaginal contraceptive desired by early birth control advocates. (shrink)

Drug regulation is fraught with inductive risk. Regulators must make a prediction about whether or not an experimental pharmaceutical will be effective and relatively safe when used by typical patients, and such predictions are based on a complex, indeterminate, and incomplete evidential basis. Such inductive risk has important practical consequences. If regulators reject an experimental drug when it in fact has a favourable benefit/harm profile, then a valuable intervention is denied to the public and a company’s material interests are needlessly (...) thwarted. Conversely, if regulators approve an experimental drug when it in fact has an unfavourable benefit/harm profile, then resources are wasted, people are needlessly harmed, and other potentially more effective treatments are underutilized. Given that such regulatory decisions have these practical consequences, non-epistemic values about the relative importance of these consequences impact the way such regulatory decisions are made (similar to the analysis of laboratory studies on the toxic effects of dioxins presented in Douglas [2000]). To balance the competing demands of the pertinent non-epistemic values, regulators must perform what I call an “inductive risk calculus.” At least in the American context this inductive risk calculus is not well-managed.

Some patients tolerate a given drug well, without adverse reactions. For others, though, an identical dose of the same medication can have toxic effects. Moreover, while a drug can be effective at relieving symptoms for some patients, it may fail to do the same for others suffering with the same disease. With such variability in treatment responses, tailoring medical interventions to individual patients has long been an aspiration of medicine. Until recently, however, medicine lacked a clear understanding of (...) the biological reasons for human variation in drug response. Attempting to adjust treatment to the individual patient, physicians have relied primarily on direct observation, trial-and-error, and, ultimately... (shrink)

Humans accumulate porphyrins in the body mostly during the course of porphyrias, diseases caused by defects in the enzymes of the heme biosynthesis pathway and that produce acute attacks, skin lesions and liver cancer. In contrast, some wild mammals and birds are adapted to accumulate porphyrins without injurious consequences. Here we propose viewing such physiological adaptations as potential solutions to human porphyrias, and suggest certain wild animals as models. Given the enzymatic activity and/or the patterns of porphyrin excretion and accumulation, (...) the fox squirrel, the great bustard and the Eurasian eagle owl may constitute overlooked models for different porphyrias. The Harderian gland of rodents, where large amounts of porphyrins are synthesized, presents an underexplored potential for understanding the carcinogenic/toxic effect of porphyrin accumulation. Investigating how these animals avoid porphyrin pathogenicity may complement the use of laboratory models for porphyrias and provide new insights into the treatment of these disorders. (shrink)

In this article, it is hypothesized that a fundamental chemical reactivity exists between some non‐lipid constituents of cellular membranes and ester‐based lipids, the significance of which is not generally recognized. Many peptides and smaller organic molecules have now been shown to undergo lipidation reactions in model membranes in circumstances where direct reaction with the lipid is the only viable route for acyl transfer. Crucially, drugs like propranolol are lipidated in vivo with product profiles that are comparable to those produced in (...) vitro. Some compounds have also been found to promote lipid hydrolysis. Drugs with high lytic activity in vivo tend to have higher toxicity in vitro. Deacylases and lipases are proposed as key enzymes that protect cells against the effects of intrinsic lipidation. The toxic effects of intrinsic lipidation are hypothesized to include a route by which nucleation can occur during the formation of amyloid fibrils. (shrink)

While cancer rates continue to increase, therapy has dramatically decreased the mortality rates. The increased efficacy of current therapies may unfortunately have profound toxic effects on gamete function in both adolescent and reproductive age groups, with infertility as an expected consequence of cancer therapy. Significant progress in the advancement of fertility preservation therapies provides realistic options for future fertility in cancer survivors. However, a number of challenging issues need to be considered when presenting fertility preservation options. This overview (...) highlights some of these considerations including religious-cultural-ethical values, access to care and cost of services, developmental capacity and consent, and posthumous reproduction.

Cancer rates in men and women of reproductive age have continued to increase in recent years; however, therapy has dramatically decreased the mortality rates. Since 1990, the prevalence of cancer survivors in young adults increased from 1 in 1,000 to 1 in 250 patients due to more aggressive therapies. Current therapies may have profound toxic effects on gamete function with infertility as an expected consequence of cancer therapy. Depending on the site and stage of cancer, age of the (...) patient, and the type of treatment, approximately 90% of men and women diagnosed with cancer may be at risk of permanent infertility.Fertility preservation has emerged as a discipline dedicated to improving the future reproductive potential of cancer survivors. Significant progress in the advancement of fertility preservation therapies and a heightened awareness of the availability of therapies has occurred in the past 10 years. The American Society of Clinical Oncology and the American Society of Reproductive Medicine have advanced these efforts by formally recognizing the importance of fertility awareness. (shrink)

Here, I wish to pursue an analysis of the potential link between the thinkers Félix Guattari and Bernard Stiegler as I see in both thinkers a profound rumination of the question of therapeutic care and curation at the institutional level. My concern is with the institutional object and its deadly repetitions. By and through agitating the coefficient of transversality, my argument is that this might problematize the dyadic and sometimes dysfunctional transindividual relationships between doctor and patient, teacher and pupil. My (...) concern is with the passage from the machinic objet petit ‘a’ in Lacan to Winnicott’s transitional object (objet petit ‘b’), and then beyond their functions to the institutional object itself which Guattari idiosyncratically calls the objet petit ‘c’. The rationale behind this move is to consider how the mediating third object needs to be recast in light of the poisonous and addictive nature of transitional objects such as smartphone technology. My point is that we must rethink the pharmacological possibility of the incorporation of the transitional object at the institutional level, which is to say, to understand the relationship between institutional objects such as the therapeutic club and the transitional object (digital technologies) in order to appreciate critically the toxic effects of the latter. Yet we also must understand the pharmacological or therapeutic aspects of the transitional object in itself, which is to say to understand its precise curative usage at the institutional level.

In lieu of an abstract, here is a brief excerpt of the content:Philosophy and Literature 27.2 (2003) 444-449 [Access article in PDF] Psychoanalysis and Morality Eugene Goodheart Equals, by Adam Phillips; 246 pp. New York: Basic Books, 2002, $25.00. I THINK I WOULD RECOGNIZE an unattributed essay by Adam Phillips by its manner. Every serious writer aspires to such recognition. A comment on the book jacket of his latest collection of essays Equals tells us that his "territory is complication," though (...) "he reports back in the simplest of words." The words may be simple, but the movement of thought through the sentence, the paragraph and an entire essay is not. His way with complication, as I hope to show, is not always to Phillips's credit. The difficulty in reading him is in trying to know where he or she is being taken. The complication often leads to inconclusiveness, which is not a fault if the problem is insoluble or the situation genuinely intractable. Too often, however, the complication seems to reflect a love of it for its own sake. On other occasions, it degenerates into obscurantism.When Phillips does take a stand, he deliberately plants himself on shifting sands. As his title suggests, he is an egalitarian democrat, to which he brings the perspective of psychoanalysis. (He was Principal Child Psychotherapist at Charing Cross Hospital in London.) All hierarchy is anathema, all claims to superiority are to be resisted. Authority turns into authoritarianism. These are my sentences, uttered in an apodictic style, foreign to that of Phillips, but they reflect a view (his view) that the prose sometimes blurs. In its psychoanalytic application, the psychoanalyst is or should be unseated from his superior [End Page 444] position. Both the analyst and the analysand need to listen to what each has to say without passing (premature?) judgment, a model for all human interactions. (Phillips does not say whether the listener is permitted to distinguish sense from nonsense.) Conflict should be the rule, for where there is no conflict there is suppression. (But conflict on either side usually presupposes a desire to impose one's will on another. Is there a distinction to be made between fruitful and destructive conflict? Again Phillips has nothing to say on the subject.) As for the meaning of equality, he avoids all the real-life obstacles to genuine equality. He approves of Chantal Mouffe's version in which there can never be "an equality of wealth, or talent or beauty," but rather "an equality of rivenness, an equality of unknowingness, the equality of there being no foundations to master." I am not sure I understand what it means to be equal in rivenness. I believe that we are all unknowing in many ways, but not that we are equally unknowing. Is equality (in the presence?) of no foundations the same as equality in the prospect of death? In any event, I'm pretty sure that no authoritarian person or institution would be much troubled when faced with these banners of equality.Yet equality is a serious matter for Phillips, so serious that in another essay he is troubled by the threat that laughter presents. In a characteristically tortuous essay in which he tries conscientiously to sort out the benign and malign effects of mockery and ridicule, he ends by concluding that mockery is "the emotional terror of democracy" and "that what is always being ridiculed is our wish to be together, our secret affinity for each other." Always? Phillips of course knows the pleasures of ridicule, even its benignly toxic effect on our self-importance. But he begins from such an extreme position of its noxiousness (at the beginning of the essay he cites Primo Levi's initial response to the concentration camp as a joke: how could it possibly be what it purports to be?) that he cannot shake himself of the solemnity of his democratic conviction to allow a place for the human comedy. I wonder too at the authority of his claim for "our secret affinity for each other." The difficulty of democracy or togetherness for many or at least some may be precisely the secret aversion that they have for... (shrink)

Numerous individual differences determine the effectiveness of the multiple external reinforcement contingencies that control drug seeking behavior. Differences in the capacity to frame reinforcement and also the toxic effects of drugs modulate susceptibility to addiction. As a result, not all individuals are at the same degree of risk for addiction.

Multidrug resistance resulting from expression of an energy‐dependent drug efflux pump encoded by the human MDR1 gene is a major impediment to effective cancer therapy. Pharmacologic intervention aimed at inhibiting this multidrug transporter should improve existing chemotherapy of human cancer, but drug development has been delayed by the difficulty and expense of developing valid animal models. Using recombinant DNA technology, a transgenic mouse has been engineered whose bone marrow is protected from the toxic effects of chemotherapy by expression (...) of the MDR1 gene. This animal system allows the rapid screening of drugs which inhibit the multidrug transporter and heralds a new era of using transgenic animals for pharmacologic screening. (shrink)
