Objective: To examine the current ethical review process of ethics committees in a non-pharmacological trial from the perspective of a clinical investigator.Design: Prospective collection of data at the Study Centre of the German Surgical Society on the duration, costs and administrative effort of the ERP of a randomised controlled multicentre surgical INSECT Trial between November 2003 and May 2005.Setting: Germany.Participants: 18 ethics committees, including the ethics committee handling the primary approval, responsible overall for 32 clinical sites throughout (...) Germany. 8 ethics committees were located at university medical schools and 10 at medical chambers. Duration was measured as days between submission and receipt of final approval, costs in euros and administrative effort by calculation of the product of the total number of different types of documents and the mean number of copies required .Results: The duration of the ERP ranged from 1 to 176 days. The median duration was 26 days at MSUs compared with 34 days at medical chambers. The total cost was €2947. 1 of 8 ethics committees at universities and 8 of 10 at medical chambers charged a median fee of €162 . The administrative effort for primary approval was 30. Four ethics committees required a higher administrative effort for secondary approval .Conclusion: The ERP for non-pharmacological multicentre trials in Germany needs improvement. The administrative process has to be standardised: the application forms and the number and content of the documents required should be identical or at least similar. The fees charged vary considerably and are obviously too high for committees located at medical chambers. However, the duration of the ERP was, with some exceptions, excellent. A centralised ethics committee in Germany for multicentre trials such as the INSECT Trial can simplify the ERP for clinical investigators in and outside the country. (shrink)

BackgroundSocial cognitive impairments adversely affect social functioning in patients with schizophrenia. Although pharmacological interventions have been suggested to provide some benefits on social cognition, little information is available on the comparative efficacy of pharmacotherapy. Thus, the aim of this planned systematic review and network meta-analysis is to perform a quantitative comparison of the effects of various psychotropic drugs, including supplements, on social cognition disturbances of schizophrenia.MethodsThe literature search will be carried out using the PubMed, Embase, Cochrane Central Register of (...) Controlled Trials, PsycINFO, ClinicalTrials.gov, and International Clinical Trials Registry Platform databases from inception onward. Randomized controlled trials that examined the efficacy of drugs in social cognitive disturbances will be included, based on the most recent studies and the broader literature than previously searched. This protocol defines a priori the methods that will be used for study selection, data collection, quality assessment, and statistical syntheses.DiscussionThe findings this work are expected to help promote the development of better therapeutics of social cognitive impairments in schizophrenia and related psychiatric conditions.Systematic Review Registration[www.crd.york.ac.uk/prospero], identifier [CRD42021293224].

It is a commonplace of the critical innovation literature that experiment has replaced mass production as the driving force of accumulation. But while many theorists have explored the politics and dynamics of such economies of experiment under the rubric of ‘immaterial’, cognitive or affective labour, few have examined the intersection of labour, experiment and the speculative in the clinic. Taking the clinic as representative of contemporary transformations in the commodity-form, labour and innovation, this article will look at recent attempts to (...) reform the clinical trial, arguing that these developments represent a far-reaching shift in our understanding of medicine. First, I investigate recent efforts (associated with the discourse of ‘translational medicine’) to rethink the interface between experimental lab-based science and the clinic. I also look at closely associated efforts to reintroduce an element of experimental surprise into the clinical trial process itself, through the adoption of novel trial designs. If the randomized controlled trial was conceived essentially along the lines of a product testing procedure, recent efforts have attempted to reintroduce surprise into the testing process itself – in other words, to invent a trial process capable of producing unexpected events as leads for further innovation. I then move from the experimental clinic to what I call the distributed experiment. Here I focus on efforts to outsource pharmacological innovation to a distributed public of patients through the use of social networking software. These platforms allow drug developers to escape the limits of the conventional clinical trial by tracking the experimental practices taking place in the distributed clinic of unregulated drug consumption.

Apathy and depression are frequently observed as behavioral and psychological symptoms of dementia, respectively, and are important for ensuring adequate care. This study aims to explore effective non-pharmacological interventions for apathy and depression with mild cognitive impairment and dementia. Five search engines including PubMed, Scopus, CINAHL, PsycInfo, and Web of Science were used to extract relevant studies. Inclusion criteria were studies that involved participants who were diagnosed with MCI or dementia, included quantitative assessments of each symptom, and employed randomized (...) controlled trials. Twenty studies were extracted, with interventions have been conducted in care facilities, the community, and hospitals. Participants in many studies had MCI or mild-to-moderate dementia but were not diagnosed with the subtypes of dementia. Few studies had set apathy and depression as the primary outcomes of non-pharmacological interventions. The findings suggested that emotional and stimulation-oriented approaches to apathy and depression would be useful for people with MCI or mild-to-moderate dementia. It would be helpful for therapists to assess the clinical features of the target symptoms for selecting suitable interventions. Additionally, increasing the number of randomized controlled trials focusing on apathy or depression as primary outcomes would offer a more definite conclusion for future systematic reviews.

Severe Traumatic Brain Injury (TBI) remains a major cause of death and disability afflicting mostly young adult males and elderly people, resulting in high economic costs to society. Therapeutic approaches focus on reducing the risk on secondary brain injury. Specific ethical issues pertaining in clinical testing of pharmacological neuroprotective agents in TBI include the emergency nature of the research, the incapacity of the patients to informed consent before inclusion, short therapeutic time windows, and a risk-benefit ratio based on concept (...) that in relation to the severity of the trauma, significant adverse side effects may be acceptable for possible beneficial treatments. Randomized controlled phase III trials investigating the safety and efficacy of agents in TBI with promising benefit, conducted in acute emergency situations with short therapeutic time windows, should allow randomization under deferred consent or waiver of consent. Making progress in knowledge of treatment in acute neurological and other intensive care conditions is only possible if national regulations and legislations allow waiver of consent or deferred consent for clinical trials.

Philosophical discussions on causal inference in medicine are stuck in dyadic camps, each defending one kind of evidence or method rather than another as best support for causal hypotheses. Whereas Evidence Based Medicine advocates the use of Randomised Controlled Trials and systematic reviews of RCTs as gold standard, philosophers of science emphasise the importance of mechanisms and their distinctive informational contribution to causal inference and assessment. Some have suggested the adoption of a pluralistic approach to causal inference, and an inductive (...) rather than hypothetico-deductive inferential paradigm. However, these proposals deliver no clear guidelines about how such plurality of evidence sources should jointly justify hypotheses of causal associations. We here develop such guidelines by first giving a philosophical analysis of the underpinnings of Hill’s viewpoints on causality. We then put forward an evidence-amalgamation framework adopting a Bayesian net approach to model causal inference in pharmacology for the assessment of harms. Our framework accommodates a number of intuitions already expressed in the literature concerning the EBM vs. pluralist debate on causal inference, evidence hierarchies, causal holism, relevance, and reliability.

BackgroundThe Authors have laid out an analysis of Italian COVID-19 confirmed data and fatality rates, pointing out how a dearth of health care resources in northern regions has resulted in hard, ethically challenging decisions in terms of granting patient access to intensive care units (ICU).Main textHaving to make such decisions certainly entails substantial difficulties, and that has led many health care professional to seek ethical guidance. The Italian Society of Anesthesia, Analgesia, Resuscitation and Intensive Care (SIAARTI) has attempted to meet (...) that growing need by a set of recommendations, applying “clinical soundness” as a beacon standard; that approach tends to prioritize patients with higher life expectancy, which could be characterized as a “moderately utilitarian” approach. Yet, such a selection has engendered daunting ethical quandaries. The authors believe it can only be warranted and acceptable if rooted in a transparent decision-making process and verifiable, reviewed criteria. Moreover, the authors have stressed how clinical experimentation in a pandemic setting is a subtext of great interest from an ethical perspective. In Italy, no drug therapy and trials were undertaken for COVID-19 patients for a rather long period of time. When the epidemic was already circulating, an intervention proved necessary on the system of administrative procedures, aimed at expediting the authorization and validation of protocols, then bogged down by bureaucracy. A new system has since been instituted by a government decree that was signed about one month after the first Covid-19 case was officially recorded in the country. Such a swift implementation, which took just a few weeks, is noteworthy and proves that clinical trials can be initiated in a timely fashion, even with a pandemic unfolding. The concerted, action of supportive care and RCTs is the only way to attain effective forms of treatments for COVID-19 and any other future outbreak.ConclusionsThe authors have arrived at the conclusion that the most effective and ethically sound response on the part of any national health care system would be to adequately reconfigure its organizational mechanisms, by making clinical trials and all related administrative procedures consistent with the current state of emergency.

Abstract:A placebo is an intervention that is believed to lack specific pharmacological or physiological efficacy for a patient's condition. While placebo-controlled trials are considered the gold standard when it comes to researching and testing new pharmacological treatments, the use of placebos in clinical practice is more controversial. The focus of this case study is an undisclosed placebo trial used as an attempt to diagnose a patient's complex and unusual symptomology. In this case, the placebo was used not (...) just as a treatment, but as a diagnostic intervention in order to determine the best course of treatment for a patient. Could the deceptive use of a placebo be justified in clinical practice on the grounds of beneficence? (shrink)

On the basis of critical discussions which have taken place in recent years in the Federal Republic of Germany, certain methodological, ethical and legal problems arising in relation to controlled trials are discussed. Because of methodological inconsistencies inherent in the experimental approach, the efficacy of a drug must in any case be judged by physicians. This leads to major ethical and even--at least in Germany--legal problems which impose considerable limits on the feasibility of controlled trials in Germany. Editor's note: This (...) paper is written at the invitation of the journal, following the considerable controversy on the ethics of clinical trials in the European Journal of Clinical Pharmacology (8-11). A critical commentary follows the paper with a short response from the authors and a further response from the commentator. (shrink)

This article examines an often neglected topic in the history of science, namely clinical observation, specifically the objectivity and knowledge production associated with therapeutic trials. It will describe an eighteenth and nineteenth century pharmacological concept of objectivity and exemplify that concept using late nineteenth century European cocaine research. As conceived within clinical drug research, this concept of objectivity does not correspond with those described by Daston and Galison in their seminal book Objectivity (2007). I will explore the implications of (...) this “new” concept of objectivity—as compared to the “old” ones postulated by Daston and Galison—for their core propositions. (shrink)

The physician who upholds the Hippocratic oath is supposed to be loyal to his or her patients. This requires choosing only the therapy that the physician believes is best for the patient. However, knowing what is best requires randomized clinical trials. Thus, clinicians must be willing to recruit their patients to be assigned at random to one of two therapies in order to determine which is best based on the highest standards of pharmacological science.

Over the past decade AIDS research has turned toward the use of pharmacology in HIV prevention, including pre-exposure prophylaxis (PrEP): the use of HIV medication as a means of preventing HIV acquisition in those who do not have it. This paper explores the contradictory reasons offered in support of PrEP—to empower women, to provide another risk-reduction option for gay men—as the context for understanding the social meaning of the experimental trials that appear to show that PrEP works in gay men (...) and heterosexual couples but not single women. The PrEP debates reveal the different ideas about “demedicalization” in the earlier gay health and women’s health movements and highlight the relationship between health activism and critique of research ethics in the context of a global pharmaceutical market.

Within the world of pharmacology, the male body has traditionally been taken as the biological norm. Coupled with this, concern about danger to the unborn foetus has meant that, until very recently, ‘women of childbearing potential’ were routinely excluded from most of the early phases of clinical drug testing. Consequently, most drugs tested during Phase I trials were initially carried out on healthy male volunteers. During subsequent phases when drugs were tested on patients, women remained largely under-represented. As a result, (...) some drugs prescribed for women have later been discovered to be lacking in efficacy, and women are more likely to suffer adverse drug reactions than men. The exclusion of women during the early phases of clinical drug trials has now been lifted and drugs are currently being more widely tested on women. This paper examines the differing political and ethical positions adopted by the pharmaceutical industry, drug regulators, pharmacologists, women's groups and patient activists in relation to the exclusion and inclusion of women in clinical drug trials.

Pregnancy is a frequently applied exclusion criteria for many forms of research. Common justifications for this exclusion include the potential for teratogenicity, as well as the potential for physiologic changes in pregnancy to impact the research itself. The systematic exclusion of pregnant persons from clinical studies has created a significant gap in knowledge regarding medication safety and efficacy in pregnancy, which continues to cause significant harm to pregnant persons in need of medical therapy. To produce meaningful data and facilitate effective (...) knowledge translation to the clinical setting, special consideration to the pharmacology of pregnancy, as well as to outcomes of concern for this population is essential. The exclusion of pregnant participants from research is not ethically justifiable, as it violates the principles of autonomy, justice and nonmaleficence. While the inclusion of pregnant patients in research presents it’s own challenges, with appropriate methodological, ethical, and clinical considerations, we may be able to narrow the knowledge gap and improve drug availability and safety for pregnant patients and their children.

The prevalence of cognitive impairment in hemodialysis patients is extremely high. Despite the well-documented benefits of interventions on cognitive function, there is a widespread call for effective strategies that will show the long-term consequences in patients undergoing dialysis. The aim of this research protocol was to investigate the effect of cognitive training combined with physical exercise on cognitive function, physical performance, and frailty indicators in the HD population. We will conduct a randomized controlled intervention trial to examine the effects (...) of a combined non-pharmacological intervention in the form of intradialytic physical exercise and intradialytic cognitive training on cognitive function, indicators of frailty, and physical performance measures in HD patients. The group of patients receiving the study intervention will be compared to the control group receiving standard HD care. The duration of the intervention will be 12 weeks. We will use sensitive instruments to assess cognitive functions. The primary outcome of the study at 12 weeks will be performance on the Alertness subtest of the computerized Test of Attentional Performance. Secondary study outcomes are: Performance in other domains of cognitive function, physical fitness, and assessment of frailty. Study outcomes will be assessed at baseline, immediately after the 12-week intervention, and 6 months after the end of the study without specific further intervention. This study will be among the first to test the synergistic effects of a uniquely designed physical exercise and cognitive training intervention on functional status in HD patients. We believe our results will contribute to dementia prevention research by demonstrating the long-term efficacy of our combined intervention.Clinical Trial Registration:ClinicalTrials.Gov, NCT05150444.

IntroductionTranscranial magnetic stimulation is a consolidated procedure for the treatment of depression, with several meta-analyses demonstrating its efficacy. Theta-burst stimulation is a modification of TMS with similar efficacy and shorter session duration. The geriatric population has many comorbidities and a high prevalence of depression, but few clinical trials are conducted specifically for this age group. TBS could be an option in this population, offering the advantages of few side effects and no pharmacological interactions. Therefore, our aim is to investigate (...) the efficacy of TBS in geriatric depression.Clinical trial registration[https://clinicaltrials.gov/ct2/], identifier [NCT04842929]. (shrink)

In recent years, there has been a particular emphasis placed on conducting randomized controlled trials (RCTs) that compare the relative efficacy of psychosocial and pharmacological interventions. This article addresses relevant ethical considerations in the conduct of these treatment trials, with a focus on RCTs with children. Ethical concerns, including therapeutic misconception, treatment preference, therapeutic equipoise, structure of treatments, and balancing risks versus benefits, are introduced through a clinical scenario and discussed as they relate to psychotherapy versus medication RCTs. In (...) each case, suggestions are made for researchers seeking to minimize the impact of these ethical concerns on research participants. (shrink)

The expert clinical community is split about whether the difference between antidepressant treatment and treatment with placebos stems from the efficacy of the drug or from subjects’ heightened expectancy enhanced by side effects—i.e., enhanced placebo effects. Proving whether pharmacological efficacy has been established reliably by randomized controlled trials of antidepressant drugs is difficult, primarily because substituting a placebo for an effective treatment in the control arm of a trial is ethically questionable. I argue that clinical equipoise permits the (...) use of active placebo controls in trials that test antidepressants. Placebo controls for drug trials are ethically defensible and scientifically justified when we have evidence that a standard treatment might only work because of enhanced placebo effects, and when a respectable minority of the expert clinical community endorses these concerns.

Deep brain stimulation is part of state-of-the-art treatment for medically refractory Parkinson’s disease, essential tremor or primary dystonia. However, there are multiple movement disorders that present after a static brain lesion and that are frequently refractory to medical treatment. Using Holmes tremor as an example, we discuss the effectiveness of currently available treatments and, performing simulations using a Markov Chain approach, propose that DBS with iterative parameter optimization is expected to be more effective than an approach based on sequential trials (...) of pharmacological agents. Since, in DBS studies for HT, the thalamus is a frequently chosen target, using data from previous studies of lesion connectivity mapping in HT, we compared the connectivity of thalamic and non-thalamic targets with a proxy of the HT network, and found a significantly higher connectivity of thalamic DBS targets in HT. The understanding of brain networks provided by analysis of functional connectivity may thus provide an informed framework for proper surgical targeting of individual patients. Based on these findings, we argue that there is an ethical imperative to at least consider surgical options in patients with uncommon movement disorders, while simultaneously providing consistent information regarding the expected effectiveness and risks, even in a scenario of surgical-risk aversion. An approach based on n-of-1 DBS trials may ultimately significantly improve outcomes while informing on optimal therapeutic targets and parameter settings for HT and other disabling and rare movement disorders.

BackgroundIndividuals with early phase cognitive impairment are frequently affected by existential distress, social avoidance and associated health issues. The demand for efficient psychological support is crucial from both an individual and a societal perspective. We have developed a novel psychological intervention manual for providing a non-medical path to enhanced psychological health in the cognitively impaired population. The current article provides specific information on the randomized controlled trial -design and methods. The main hypothesis is that participants receiving PIPCI will increase (...) their psychological flexibility compared to participants in the active control group and the waiting list control group. The secondary hypotheses are that participants receiving PIPCI will improve psychological health compared to participants in the active control group and the waiting list control group.Materials and MethodsThis three-arm RCT will recruit participants from the cognitive centers at Karolinska University Hospital in Stockholm and randomize approximately 120 individuals in the early phase of cognitive impairment to either an experimental group, an active control group or a waiting list control group. Intervention outcome will be evaluated with self-report questionnaires on physical and psychological aspects of health, cognitive assessment, biological markers and health care costs. Assessments will be performed at pre- and post-intervention, as well as at a 6-month follow-up.DiscussionThe development of a potentially feasible and effective psychological intervention tailored for early phase cognitive impairment has the potential to advance the non-pharmacological intervention field. This is especially important given the extensive burden for many affected individuals and their families and the current lack of effective treatments. If the psychological intervention discussed here shows feasibility and efficacy, there is potential for far-reaching healthcare implications for patients with early cognitive impairment at risk of developing dementia.Clinical Trial RegistrationClinicalTrials.gov: NCT04356924.

Research ethics committees (RECs) evaluate whether the risk-benefit ratio of a study is acceptable. Decentralized clinical trials (DCTs) are a novel approach for conducting clinical trials that potentially bring important benefits for research, including several collateral benefits. The position of collateral benefits in risk-benefit assessments is currently unclear. DCTs raise therefore questions about how these benefits should be assessed. This paper aims to reconsider the different types of research benefits, and their position in risk-benefit assessments. We first propose a categorization (...) of research benefits, based on the types of benefits that can be distinguished from the literature and ethical guidelines. Secondly, we will reconsider the position of collateral benefits. We argue that these benefits are not fundamentally different from other benefits of research and can therefore be included in risk-benefit assessments of DCTs. (shrink)

In light of the World Anti Doping Agency’s 2013 Code Revision process, we critically explore the applicability of two of three criteria used to determine whether a method or substance should be considered for their Prohibited List, namely its (potential) performance enhancing effects and its (potential) risk to the health of the athlete. To do so, we compare two communities of human guinea pigs: (i) individuals who make a living out of serial participation in Phase 1 pharmacology trials; and (ii) (...) elite athletes who engage in what is effectively ‘unregulated clinical research’ by using untested prohibited or non-prohibited performance enhancing substances and methods, alone or in combination. Our comparison sheds light on norms of research ethics that these practices exacerbate with respect to the concepts of multiplicity, visibility, and consistency. We argue for the need to establish a proper governance framework to increase the accountability of these unregulated research practices in order to protect the human guinea pigs in elite sports contexts, and to establish reasonable grounds for the performance enhancing effects, and the risks to the health of the athlete, of the methods and substances that might justify their inclusion on the Prohibited List.

"Correlation is not causation" is one of the mantras of the sciences—a cautionary warning especially to fields like epidemiology and pharmacology where the seduction of compelling correlations naturally leads to causal hypotheses. The standard view from the epistemology of causation is that to tell whether one correlated variable is causing the other, one needs to intervene on the system—the best sort of intervention being a trial that is both randomized and controlled. In this paper, we argue that some purely (...) correlational data contains information that allows us to draw causal inferences: statistical noise. Methods for extracting causal knowledge from noise provide us with an alternative to randomized controlled trials that allows us to reach causal conclusions from purely correlational data. (shrink)

Often regarded simply as a nuisance in clinical drug trials in which the aim is to separate drug response from placebo response in a statistically significant manner, the placebo response has important implications. These implications relate to the nature of illness, the study of non-specific factors in the treatment setting that are related to clinical improvement, methods of enhancing these non-specific sources of benefit, and the neurobiology that is associated with the placebo response. Specific sources of clinical improvement in medical (...) and psychological treatment generally consist of drugs or clear interventions that appear to directly contribute to the desired treatment. Non-specific factors, on the other hand, include the clinician–patient relationship, installation of hope, relationship with authority, and other such factors that are more implicit to treatment and may contribute to the placebo response. Our understanding of how these non-specific aspects of treatment relate to clinical improvement and ways of enhancing these non-pharmacological elements of therapy may form important aspects of treatment. Furthermore, an important, albeit potentially overlooked element of the placebo response are clinical-trial designs and methodologies, themselves. Specific neurobiological changes also appear to be associated with the placebo response in at least some cases. Finally, it is suggested that the placebo response may in some instances represent a type of brain plasticity in which expectation and desire — agency — can result in specific changes in brain function that either may mirror or differ from the effects of certain drugs.

While it is comforting to believe that (...) Nazi physicians, nurses, and bioscientists were either incompetent, mad, or few in number, they were, in fact, the best in the world at the time, and the vast majority participated in the government program of "applied biology."

This paper examines the culture, the dynamics and the financial underpinnings that determine how medical research is being conducted on children in the United States. Children have increasingly become the subject of experiments that offer them no potential direct benefit but expose them to risks of harm and pain. A wide range of such experiments will be examined, including a lethal heartburn drug test, the experimental insertion of a pacemaker, an invasive insulin infusion experiment, and a fenfluramine "violence prediction" experiment. (...) Emphasis, however, is given to psychoactive drug tests because of the inherent ethical and diagnostic problems involved in the absence of any objective, verifiable diagnostic tool. Effort is made to provide readers comprehensive reference sources to evidence-based reports about the serious risks these drugs pose for adults and children so that the reader may judge whether the benefits (if any) outweigh the risks for children. The first ethical issue raised by these experiments is: did the severity of illness in these children justify their exposure to short and long-term risks? The ethics of the experiments will be evaluated by referring to existing codes of medical research ethics-the Nuremberg Code, the Declaration of Helsinki, and the federal Code of Regulations. The thirteen cases presented will demonstrate that children are being used in ever more speculative experiments, often in the absence of a therapeutic intent, but a significant chance for causing harm and / or discomfort. Some of the experiments were designed to explore the mechanisms of pathology and pharmacological interventions, or the response of neurological brain receptors to chemical provocation ("challenge"). Others were designed to test the safety or efficacy of new drugs, even to test these drugs on healthy children who were hypothesized to be "at risk." Children and adolescents have been subjected to "forced dose titration" experiments that induced a spectrum of severe adverse effects, including insomnia, extreme restlessness, agitation, (akathisia) and self-injurious behavior. FDA reports show that suicide is a significant issue in psychotropic drug trials-in pediatric trials the problem is even greater. The paper aims to demonstrate how the enactment of the Better Pharmaceuticals for Children Act (incorporated into the Food and Drug Administration Modernization Act, FDAMA), set in motion a radical shift in public policy by providing huge financial incentives to pharmaceutical companies to test new or patented drugs in children. Federal policy shifted from one aimed at protecting children by setting limits on permissible research risks, to a policy aimed at broadening the inclusion of children as test subjects. It will be shown how the FDA and the Department of Health and Human Services lifted regulatory restrictions to permit research involving greater than minimal risk to be conducted on healthy children, claiming that all children are potentially "at risk" of a future condition. Children were in this way deprived of regulatory protections. An argument will be made that the approval of nontherapeutic, harmful experiments-such as exposure of toddlers to lead poison-under the current gate keeping system raises serious doubts about the sustainability of institutional review boards (IRBs) as protectors of human research subjects. Children, who are precluded from exercising the adult human's right to informed consent, are being exploited as commodities for commercial ends. It is the position of the author that nothing less than the enactment of a federal law mandating a radical overhaul of the current research review system, with independent checks and balances, will provide children the legal protections they need. Ten specific recommendations are offered to protect children from harmful experiments. (shrink)

American orthodox medicine consolidated its professional authority in the early 20th Century on the basis of its unbiased scientific method. The centerpiece of such a method is a strategy for identifying truly effective new therapies, i.e., the randomized clinical trial (RCT). A crucial component of the RCT in illnesses without established treatment is the placebo control. Placebo effects must be identified and distinguished from pharmacological effects because placebos produce actual but unexplained therapeutic successes. The blinding necessary for a (...) proper placebo-controlled RCT therefore introduces an epistemic bias into orthodox medicine: therapeutic successes that rely upon a direct link between knowing and healing, such as placebo effects, are discarded in favor of therapeutic successes that rely upon an indirect link between knowing and healing, such as pharmacological interventions. Where the capacity to produce therapeutic results once validated the method of clinical medical science, now method validates results. The clinical consequences of this method of testing therapies include a diminished vision of the therapeutic potential of the doctor-patient relationship and of the potential human resources available for healing.

In light of the magnitude of interpersonal harm and the risk of greater harm in the future, Ingmar Persson and Julian Savulescu have argued for pharmacological enhancement of moral behaviour. I discuss moral bioenhancement as a set of collective action problems. Psychotropic drugs or other forms of neuromodulation designed to enhance moral sensitivity would have to produce the same or similar effects in the brains of a majority of people. Also, a significant number of healthy subjects would have to (...) participate in clinical trials testing the safety and efficacy of these drugs, which may expose them to unreasonable risk. Even if the drugs were safe and effective, a majority of people would have to co-operate in a moral enhancement programme for such a project to succeed. This goal would be thwarted if enough people opted out and decided not to enhance. To avoid this scenario, Persson and Savulescu argue that moral enhancement should be compulsory rather than voluntary. But the collective interest in harm reduction through compulsory enhancement would come at the cost of a loss of individual freedom. In general, there are many theoretical and practical reasons for scepticism about the concept and goal of moral enhancement. (shrink)

Anxiety is a common unpleasant reaction among patients undergoing surgery. Many non-pharmacological methods such as spiritual strength are effective in preoperative anxiety management. This study aimed to assess the effects of listening to Quran recitation on reducing preoperative anxiety. A systematic review was performed in Medline, EMBASE, Cochrane Library, PsycINFO, Arab World Research Source, and other relevant databases to collect the data. Randomized controlled trials about the effects of listening to Quran recitation on preoperative anxiety reduction in elective surgery (...) were selected without any language and date restriction. Interventions with self-reading/self-recitation were excluded. The Cochran’s Q statistic and the I2 index with 50% threshold were used for calculating the heterogeneity and inconsistency index. Subgroup analysis was conducted based on the surgery type. The funnel plot was used to evaluate the possibility of publication bias. Twelve studies were included in the qualitative synthesis and nine studies in the quantitative synthesis. The meta-analysis showed a significant anxiety reduction with listening to Quran recitation. The heterogeneity between the included studies was statistically significant. The pooled effect size of anxiety was d = −8.893 = −10.763 to −7.022). The subgroup analysis showed that listening to Quran recitation reduces anxiety in major and minor surgeries. There was no publication bias in the studies. The findings indicated that listening to Quran recitation can be considered a non-invasive and peaceful intervention to reduce preoperative anxiety in elective surgery. (shrink)

Information is usually supposed to be a prerequisite for people making decisions on whether or not to participate in a clinical trial. Previously conducted studies and research ethics scandals indicate that participants have sometimes lacked important pieces of information. Over the past few decades the quantity of information believed to be adequate has increased significantly, and in some instances a new maxim seems to be in place: the more information, the better the ethics in terms of respecting a participant’s (...) autonomy. The authors hypothesise that the dose-response curve from pharmacology or toxicology serves as a model to illustrate that a large amount of written information does not equal optimality. Using the curve as a pedagogical analogy when teaching ethics to students in clinical sciences, and also in engaging in dialogue with research institutions, may promote reflection on how to adjust information in relation to the preferences of individual participants, thereby transgressing the maxim that more information means better ethics.

Introduction Current treatments for pain have limited benefits and worrying side effects. Some studies suggest that pain is reduced when clinicians deliver positive messages. However, the effects of positive messages are heterogeneous and have not been subject to meta-analysis. We aimed to estimate the efficacy of positive messages for pain reduction. -/- Methods We included randomized trials of the effects of positive messages in a subset of the studies included in a recent systematic review of context factors for treating pain. (...) Several electronic databases were searched. Reference lists of relevant studies were also searched. Two authors independently undertook study selection, data extraction, risk of bias assessment, and analyses. Our primary outcome measures were differences in patient- or observer-reported pain between groups who were given positive messages and those who were not. -/- Results Of the 16 randomized trials (1703 patients) that met the inclusion criteria, 12 trials had sufficient data for meta-analysis. The pooled standardized effect size was −0.31 (95% confidence interval [CI] −0.61 to −0.01, p = 0.04, I2 = 82%). The effect size remained positive but not statistically significant after we excluded studies considered to have a high risk of bias (standard effect size −0.17, 95% CI −0.54 to 0.19, P = 0.36, I2 = 84%). -/- Conclusion Care of patients with chronic or acute pain may be enhanced when clinicians deliver positive messages about possible clinical outcomes. However, we have identified several limitations of the present study that suggest caution when interpreting the results. We recommend further high-quality studies to confirm (or falsify) our result. -/- FUNDING -/- Alexander Mebius research has been funded through the ERC grant "Philosophy of Pharmacology: Safety, Statistical Standards, and Evidence Amalgamation" (GA: 639276).

Different immunotherapeutic approaches are in the pipeline for the treatment of drug dependence. “Drug vaccines” aim to induce the immune system to produce antibodies that bind to drugs and prevent them from inducing rewarding effects in the brain. Drugs of abuse currently being tested using these new approaches are opioids, nicotine, cocaine, and methamphetamine. In human clinical trials, “cocaine and nicotine vaccines” have been shown to induce sufficient antibody levels while producing few side effects. Studies in humans, determining how these (...) vaccines interact in combination with their target drug, are underway. However, although vaccines can become a reasonable treatment option for drugs of abuse, there are several disadvantages that must be considered. These include i) great individual variability in the formation of antibodies, ii) the lack of protection against a structurally dissimilar drug that produces the same effects as the drug of choice, and iii) the lack of an effect on the drug desire that may predispose an addict to relapse. In addition, a comprehensive overview of several crucial ethical issues has not yet been widely discussed in order to have not only a biological approach to immunotherapy of addiction. Overall, immunotherapy offers a range of possible treatment options: the pharmacological treatment of addiction, the treatment of overdoses, the prevention of toxicity to the brain or the heart, and the protection of the fetus during pregnancy. So far, the results obtained from a small-scale experiment using vaccines against cocaine and nicotine suggest that a number of important technical challenges still need to be overcome before such vaccines can be approved for clinical use.

The formation and recall of memories are fundamental aspects of life and help preserve the complex collection of experiences that provide us with a sense of identity and autonomy. Scientists have recently started to investigate pharmacological agents that inhibit or “dampen” the strength of memory formation and recall. The development of these memory-dampening agents has been investigated for the treatment of posttraumatic stress disorder (PTSD). Currently, these agents are being tested in multicenter clinical trials and will likely soon be (...) approved for the treatment of PTSD. With advancements in technology, more targeted memory-dampening techniques may be developed in the future. Accessibility to these agents will inevitably affect one's sense of identity and also one's sense of autonomy. Therefore, it is essential that the legal and ethical implications of using these agents be examined for governments and courts to appropriately address issues that may emerge. (shrink)

Objective: The aim of the study was to identify clinical variables associated with changes in specific domains of self-reported depression during treatment by antidepressant and/or repetitive Transcranial Magnetic Stimulation in patients with Major Depressive Disorder.Methods: Data from a trial involving 170 patients with MDD receiving either venlafaxine, rTMS or both were re-analyzed. Depressive symptoms were assessed each week during the 2 to 6 weeks of treatment with the 13-item Beck Depression Inventory. Associations between depression changes on BDI13 domains, treatment (...) arm, time, and clinical variables were tested in a mixed linear model.Results: A significant decrease of self-reported depressive symptoms was observed over time. The main characteristics associated with persistent higher depressive symptomatology on Negative Self-Reference domain of the BDI13 were personality disorders, a past history of suicide attempt, age under 65 years old, and female sex.Conclusions: Early cognitive intervention targeting specifically negative self-referencing process could be considered during pharmacological or rTMS treatment for patients with personality disorders and past history of suicide attempt.

Although the use of ECT has declined dramatically from its inception, this decrease has recently shown signs of leveling out because of ECT's powerful therapeutic effect in severely ill depressed individuals who either do not respond to pharmacologic alternatives or are too ill to tolerate a relatively lengthy drug trial. Notwithstanding its therapeutic benefits, ECT has also remained a controversial treatment modality, particularly in the eye of the public. Given the unsavory qualities associated with the word “electroconvulsive,” claims of (...) possible, probable, or even certain brain damage with ECT have easily found listeners. A careful, nonselective assessment of data covering the areas of pathology, radiology, electrophysiology, biochemistry, and neuropsychology leads both to certain conclusions and to certain unanswered questions. ECT is not the devastating purveyor of wholesale brain damage that some of its detractors claim. For the typical individual receiving ECT, no detectable correlates of irreversible brain damage appear to occur. Still, there remains the possibility that either subtle, objectively undetectable persistent deficits, particularly in the area of autobiographic memory function, occur, or that a rarely occurring syndrome of more pervasive persistent deficits related to ECT use may be present. Clearly, more research directed toward answering these questions needs to be carried out so that the role of ECT can be more rigorously defined. While such research is pending, however, we cannot expect that the conditions that predispose to clinical referrals for ECT will disappear. Given the misery, anguish, and risk of death by suicide, starvation, or debilitation associated with severe depressive illness, for example, it still appears that ECT, at least for the present, must continue to be available.

The psychopharmacology of alcohol dependence is today poised at interesting crossroads. Three major drugs Naltrexone, Disulfiram and Acamprosate have been tried and tested in various trials and have many meta-analyses each to support them. While Naltrexone may reduce craving, Acamprosate scores on cost effectiveness worldwide with Disulfiram being an alcohol deterrent drug. Studies support, refute and criticize the use of each of these drugs. Combining one or more of them is also a trend seen. The most important factor in efficacy (...) has been the combination of psychosocial treatment with medication. Studies from the early 1970s to date have been reviewed and the findings presented in a manner useful for the busy clinician to judge the best pharmacological option in the management of alcohol dependence. The role of depot disulfiram, naltrexone, and medications like Topiramate and SSRIs under research for alcohol dependence, are also addressed. (shrink)

A central principle of bioethics is “subject autonomy,” the acknowledgement of the primacy of the informed consent of the subject of research. Autonomy requires informed consent — the assurance that the research participant is informed about the possible risks and benefits of the research. In fact, informed consent is difficult when a single drug is being tested, although subjects have a baseline understanding of the testing of a pharmacological agent and the understanding that they can stop taking the drug (...) if there were an adverse event. However, informed consent is even less easily achieved in the modern arena of complex new molecular and cellular therapies. In this article, we argue that as science confronts new issues such as transplantation of stem cell products, which may live within the participant for the rest of their lives, researchers must carefully consider and constantly re-examine how they properly inform subjects considering participation trials of these novel therapeutic strategies.For example, the manufacture of a vial of a cell product that consists of a collection of growing cells is very different than the production of a vial of identical pills, which can be presumed to be identical. The scientific concepts on which these cellular approaches are based may seem alien and incomprehensible to a research subject, who thinks of a clinical trial as simply the selection and testing of the most efficacious pharmaceutical agent already proven to work in preclinical animal studies. The research subject would be wrong. (shrink)

In late May 1984, Irish citizens were perturbed to hear that a thirty-one year old man died while participating, as a paid volunteer, in a clinical drug trial at the Institute of Clinical Pharmacology in Dublin. At the inquest, held in September 1984, the State Pathologist, Dr John Harbison, affirmed that the cause of death was the reaction of the trial drug Eproxindine 4/0091 with a major tranquillizer which had been given less than fifteen hours earlier as part (...) of regular treatment for a psychiatric disorder. The mixture of the two drugs, he went on to say, increased their effect by between twenty and thirty times their normal strength, and the volunteer had died of cardiac depression. (shrink)

Various historical sources from the Renaissance--including transcripts of trials for witchcraft, writings on demonology and textbooks of pharmaceutical botany--describe vegetal ointments prepared by women accused of witchcraft and endowed with marked psychoactive properties. Here, we examine the botanical composition and the possible pharmacological actions of these ointments. The results of our study suggest that recipes for narcotic and mind-altering salves were known to Renaissance folk healers, and were in part distinct from homologous preparations of educated medicine. In addition, our (...) study reveals an unexpected connection of these vegetal psychotropes with archaic chtonic beliefs, confirming the tight association between rituals and cults entered on the Underworld and the image of the Medieval witch.

The prevalence of dementia is increasing with the ever-growing population of older adults. Non-pharmacological, music-based interventions, including sensory stimulation, were reported by the Lancet Commission in 2020 to be the first-choice approach for managing the behavioural and psychological symptoms of dementia. Low frequency sinusoidal vibration interventions, related to music interventions through their core characteristics, may offer relief for these symptoms. Despite increasing attention on the effectiveness of auditory music interventions and music therapy for managing dementia, this has not included (...) low frequency vibration. This scoping review, following the JBI methodology guidelines, was conducted to investigate participants’ responses to both sound and mechanical vibration, the characteristics of the delivered interventions, methodological challenges, and the specifics of the research experiments reported. An extensive search was conducted in BMC, CINAHL, Cochrane Central Register of Controlled Trials, EMBASE, ERIC, MEDLINE, Pedro, ProQuest Central, PsycINFO, Scopus, and Web of Science. Current Controlled Trials, Clinical Trials, and Google Scholar were also searched as well as a hand search in relevant journals. Studies on adults with all types of dementia, investigating tactile low frequency sound or mechanical vibration in any context were considered. Data from eight full-length studies were extracted using the data extraction table developed by the authors and were included in the analysis and critical appraisal. Issues in quality related to, for example, control groups and blinding. Few studies addressed participants’ subjective responses to the interventions. Reporting on the intervention characteristics was unclear. It appeared more frequent sessions led to better outcomes and home-based interventions potentially addressing the issue of access and feasibility. Future research should include neuroimaging to measure and confirm the hypothesised mechanism of cerebral coherence. Standardised reporting of intervention characteristics is also needed to ensure replicability of the experiments. Higher quality research is needed to investigate the impact and effect of low frequency vibration for the symptoms of dementia and compare outcomes in meta-syntheses. (shrink)
