Translational Bioethical Decision-Making: Human Brain Organoids as a Case Study.

In an earlier essay, I advocated that translational bioethics uses the public's values, determined through social science, in its analysis of translational science technologies. It may be unclear what those values might be, and whether such a translational ethics would necessarily conclude that cutting edge technologies should not be developed. In this essay, I show the public's values relevant to human brain organoids and argue that a translational bioethics analysis using these values would support continued organoid research.

Scientism, trust, value alignment, views of nature, and U.S. public opinion about gene drive mosquitos.

Gene drive could be a powerful tool for addressing problems of conservation, agriculture, and human health caused by insect and animal pests but is likely to be controversial as it involves the release of genetically modified organisms. This study examined the social determinants of opinion of gene drive. We asked a representative sample of the U.

Translational Bioethics and Public Input.

Translational science is justified as advancing the public's interests but has no mechanism for determining these interests. Standard social science approaches would produce either unrepresentative descriptions or a cacophony of data not easily condensed into a concrete conclusion about moving forward with a translational-science project. Here, I propose that the simplifying and structuring ethics employed by institutional review boards (IRBs) be used to create social science reports of the four to six most prominent values or principles of the public regarding a biotechnology.

Neurocheck Frequency: Determining Perceptions and Barriers to Implementation of Evidence-Based Practice.

Background: Following acute brain injury, patients in the intensive care unit often undergo hourly or every-other-hour exams ("neurochecks") to monitor for neurodeterioration. We assessed health care provider attitudes towards neurocheck frequency and evaluated providers' ideal neurocheck frequency.

Methods: This was a cross-sectional, online survey distributed in Spring 2021 at a tertiary care academic medical center.

Brain organoids, consciousness, ethics and moral status.

Advances in the field of human stem cells are often a source of public and ethical controversy. Researchers must frequently balance diverse societal perspectives on questions of morality with the pursuit of medical therapeutics and innovation. Recent developments in brain organoids make this challenge even more acute.

Patient narratives of hope in stem cell technologies: Trust in biomedicine and the body's natural ability to heal itself.

The scholarship on patient hope in biomedical technologies describes two narratives of hope: the biomedical and the individual. The biomedical narrative represents patients' beliefs that the institution of science will eventually produce treatment for their disease, whereas the individual narrative represents patients' beliefs that they can alter their prognosis through affective and behavioral modifications. The distinct analytical categories of "biomedical" and "individual," however, fail to account for the fact that patient hope has been found to be much more complex.

Saccharomyces cerevisiae strains used industrially for bioethanol production.

Fuel ethanol is produced by the yeast Saccharomyces cerevisiae mainly from corn starch in the United States and from sugarcane sucrose in Brazil, which together manufacture ∼85% of a global yearly production of 109.8 million m3 (in 2019). While in North America genetically engineered (GE) strains account for ∼80% of the ethanol produced, including strains that express amylases and are engineered to produce higher ethanol yields; in South America, mostly (>90%) non-GE strains are used in ethanol production, primarily as starters in non-aseptic fermentation systems with cell recycling.

Setting ethical limits on human gene editing after the fall of the somatic/germline barrier.

The ethical debate about what is now called human gene editing (HGE) has gone on for more than 50 y. For nearly that entire time, there has been consensus that a moral divide exists between somatic and germline HGE. Conceptualizing this divide as a barrier on a slippery slope, in this paper, I first describe the slope, what makes it slippery, and describe strong barriers that arrest the slippage down to the dystopian bottom of pervasive eugenic enhancement.

Reactions to the National Academies/Royal Society Report on .

In September 2020, a detailed report on was published. The report offers a translational pathway for the limited approval of germline editing under limited circumstances and assuming various criteria have been met. In this perspective, some three dozen experts from the fields of genome editing, medicine, bioethics, law, and related fields offer their candid reactions to the National Academies/Royal Society report, highlighting areas of support, omissions, disagreements, and priorities moving forward.

Self-Interested and Altruistic Motivations in Volunteering for Clinical Trials: A More Complex Relationship.

Empirical studies have found that altruism and self-interest are the two primary motivations for enrollment in clinical trials. Some studies have shown that in some cases these two motivations are contingent upon each other, which complicates our understanding of motivation. In this study, we interviewed 27 people with Parkinson's disease about their willingness to enroll in a hypothetical clinical trial.

Mechanical Function of the Nucleus Pulposus of the Intervertebral Disc Under High Rates of Loading.

Study Design: Bovine motion segments were used to investigate the high-rate compression response of intervertebral discs (IVD) before and after depressurising the nucleus pulposus (NP) by drilling a hole through the cranial endplate into it.

Objective: To investigate the effect of depressurising the NP on the force-displacement response, and the energy absorption in IVDs when compressed at high strain rates.

Summary Of Background Data: The mechanical function of the gelatinous NP located in the center of the IVDs of the spine is unclear.

Biomedical ethics and clinical oversight in multisite observational neuroimaging studies with children and adolescents: The ABCD experience.

Observational neuroimaging studies with children and adolescents may identify neurological anomalies and other clinically relevant findings. Planning for the management of this information involves ethical considerations that may influence informed consent, confidentiality, and communication with participants about assessment results. Biomedical ethics principles include respect for autonomy, beneficence, non-maleficence, and justice.

Power and jurisdiction.

In response to Flamm and Kodish, I argue that our misunderstanding or disagreement is primarily the result of different definitions of power. I also disagree with them and claim that they are indeed using the public's ethics. Finally, I argue that there is no reason to think that bioethicists cannot have the same sort of influence in the boardroom that they have in the clinic.

Response to Callahan and Winslade.

I respond to commentaries by Daniel Callahan and William J. Winslade on my article, "Defending the Jurisdiction of the Clinical Ethicist," all of which are in this issue of JCE.

Defending the jurisdiction of the clinical ethicist.

In this essay I suggest that the bioethics profession's jurisdiction over healthcare ethics consultation is in need of reinforcement. I argue that as the profession becomes more successful, competitors will challenge the profession to justify its ethical claims and ask whose ethics the profession represents. This challenge will come more quickly as the profession tries to influence the ethics of healthcare organizations.

Faith in science in global perspective: Implications for transhumanism.

While citizens can know scientific facts, they also have faith in science - with faith defined as a firm belief for which there is no proof. Using national public opinion surveys from twelve nations from 1993 to 2010, I examine three different types of faith in science that citizens could hold. I examine temporal changes in levels of faith in science as well as the social determinants of each type of faith.

Evidence that opioids may have toll-like receptor 4 and MD-2 effects.

Opioid-induced proinflammatory glial activation modulates wide-ranging aspects of opioid pharmacology including: opposition of acute and chronic opioid analgesia, opioid analgesic tolerance, opioid-induced hyperalgesia, development of opioid dependence, opioid reward, and opioid respiratory depression. However, the mechanism(s) contributing to opioid-induced proinflammatory actions remains unresolved. The potential involvement of toll-like receptor 4 (TLR4) was examined using in vitro, in vivo, and in silico techniques.

The contribution of spatial cues to memory: direction, but not cue, changes support response reversal learning.

In four experiments, rats were trained on a response problem followed by three reversals. Rats that changed rooms between acquisition and reversals learned the reversals in fewer trials than rats that remained in the same room, even when distal visual cues were limited. Changes in orientation, even in the same room, also facilitated response reversal learning.

FE stress analysis of the interface between the bone and an osseointegrated implant for amputees--implications to refine the rehabilitation program.

Background: The direct anchorage of lower-limb prosthesis to the bone has been shown to be an excellent alternative for amputees experiencing complications in using a conventional prosthetic socket. During rehabilitation phase, amputees are asked to apply static loading on the abutment perpendicular to a weigh scale to prepare the bone to tolerate the forces likely to be developed during walking. The weigh scale measures only the vertical force.
