People with disabilities (PWD) comprise a significant part of the population yet experience some of the most profound health disparities. Among the greatest barriers to quality care are inadequate health professions education related to caring for PWD. Drawing upon the expertise of health professions educators in medicine, public health, nursing, social work, and physician assistant programs, this forum showcases innovative methods for teaching core disability skills and concepts grounded in disability studies and the health humanities. Each of the essays offers practical guidance for developing curricular interventions appropriate for students at various levels of training and familiarity with disability to be implemented in classroom discussions, case-based learning, lectures, panels, and clinical simulations across the full spectrum of pre-health and health professions education., (© 2023.

Autism research frequently seeks to evaluate interventions or inform their development. Unfortunately, researchers often assume that autism intervention should reduce autistic traits, effectively setting as a goal of treatment that autistic people attempt to "pass" as nonautistic. A growing body of evidence highlights serious potential harms from passing demands. We discuss why it is important for institutional review boards (IRBs) to scrutinize autism research for clinical passing demands, and we document the existence of such demands in outcome measures commonly employed in autism research. We propose an ethical framework for IRBs and others to make use of in evaluating the ethical appropriateness of particular treatment goals in autism intervention or intervention-adjacent research, emphasizing that treatment goals should be in pursuit of a beneficial nonpassing purpose and be the least burdensome means of accomplishing such a purpose. We also highlight potential promising practices for IRBs, investigators, and other stakeholders seeking to address these issues in autism research., (© 2023 by The Hastings Center.

We suggest that there is confusion between why consciousness developed and what additional functions, through continued evolution, it has co-opted. Consider episodic memory. If we believe that episodic memory evolved solely to accurately represent past events, it seems like a terrible system-prone to forgetting and false memories. However, if we believe that episodic memory developed to flexibly and creatively combine and rearrange memories of prior events in order to plan for the future, then it is quite a good system. We argue that consciousness originally developed as part of the episodic memory system-quite likely the part needed to accomplish that flexible recombining of information. We posit further that consciousness was subsequently co-opted to produce other functions that are not directly relevant to memory per se, such as problem-solving, abstract thinking, and language. We suggest that this theory is compatible with many phenomena, such as the slow speed and the after-the-fact order of consciousness, that cannot be explained well by other theories. We believe that our theory may have profound implications for understanding intentional action and consciousness in general. Moreover, we suggest that episodic memory and its associated memory systems of sensory, working, and semantic memory as a whole ought to be considered together as the conscious memory system in that they, together, give rise to the phenomenon of consciousness. Lastly, we suggest that the cerebral cortex is the part of the brain that makes consciousness possible, and that every cortical region contributes to this conscious memory system., Competing Interests: The authors declare no conflicts of interest.

Whether to treat autism as exculpatory in any given circumstance appears to be influenced both by models of autism and by theories of moral responsibility. This article looks at one particular combination of theories: autism as theory of mind challenges and moral responsibility as requiring appropriate experience of the reactive attitudes. In pursuing this particular combination of ideas, we do not intend to endorse them. Our goal is, instead, to explore the implications of this combination of especially prominent ideas about autism and about moral responsibility. These implications can be quite serious and practical for autists and those who interact directly with autists, as well as for broader communities as they attend to the fair, compassionate, and respectful treatment of increasing numbers of autistic adults. We find that these theories point to a limited range of situations in which autists should not be blamed for transgressive actions for which neurotypical individuals should be blamed. We build on what others have written on these issues by bringing in a recent cognitive model of the role theory of mind plays in empathy, by discussing the social implications of the theoretical findings, and by raising questions about the compatibility of reactive attitude theories of moral responsibility with the neurodiversity approach to autism., (© 2017 John Wiley & Sons Ltd.)

Study Objective: The study objective is to examine the analgesic effect of 3 doses of dexamethasone in combination with low concentration local anesthetics to determine the lowest effective dose of dexamethasone for use as an adjuvant in supraclavicular brachial plexus nerve block., Design: The design is a prospective randomized double-blinded clinical study., Setting: The setting is an academic medical center., Patients: The patients are 89 adult patients scheduled for shoulder arthroscopy., Interventions: All patients were randomly assigned into 1 of 4 treatment groups: (i) bupivacaine, 0.25% 30 mL; (ii) bupivacaine, 0.25% 30 mL with 1-mg preservative-free dexamethasone; (iii) bupivacaine, 0.25% 30 mL with 2-mg preservative-free dexamethasone; and (iv) bupivacaine, 0.25% 30 mL with 4-mg preservative-free dexamethasone. All patients received ultrasound-guided supraclavicular brachial plexus nerve blocks and general anesthesia., Measurements: The measurements are the duration of analgesia and motor block., Main Results: The median analgesia duration of supraclavicular brachial plexus nerve block with 0.25% bupivacaine was 12.1 hours; and 1-, 2-, or 4-mg dexamethasone significantly prolonged the analgesia duration to 22.3, 23.3, and 21.2 hours, respectively (P = .0105). Dexamethasone also significantly extended the duration of motor nerve block in a similar trend (P = .0247)., Conclusion: Low-dose dexamethasone (1-2 mg) prolongs analgesia duration and motor blockade to the similar extent as 4-mg dexamethasone when added to 0.25% bupivacaine for supraclavicular brachial plexus nerve block., (Copyright © 2015 Elsevier Inc.

There has been little empirical research into misconduct and misbehavior among community research workers who recruit and collect data in vulnerable and marginalized health populations and are also members of those same communities. We conducted qualitative interviews with community research workers and traditional research assistants to understand the context and consequences of misbehaviors that pose a threat to research ethics and data integrity. In our sample, more community research workers acknowledged engaging in research wrongdoing than did traditional research assistants. These behaviors were most prevalent among community research workers who were not well-integrated into the research team. We suggest best practices for investigators to promote an environment that supports research integrity in research projects that employ community research workers.

In a time when we as a society are in the process of deciding what our basic rights to health care are, it is critically important for us to have a full and complete understanding of what constitutes health. We argue for an analysis of health according to which certain states are healthy not in themselves but because they allow an individual to reach actual goals. Recognizing that the goals of an individual considered from the point of view of biology and the goals of the same individual considered as an agent in the world might be different, we introduce a distinction between the health of an individual qua organism and the health of an individual qua person. We then argue that this distinction characterizes the evaluations made by patients and healthcare providers better than the widely discussed distinction between disease and illness.

The Sentorr is a gas chromatograph that monitors Pa2 and PaCO2 every 4 min from a probe placed through an intraarterial cannula. The accuracy of this device and complications resulting from its use were studied in 46 patients undergoing cardiac surgical procedures with oxygen to nitrous oxide-halothane anesthesia. Sentorr blood-gas values were compared with simultaneous samples analyzed with standard electrodes. During relatively steady states of respiration and circulation, and in the lower (50-125 torr) range of oxygen tensions, the measurements correlated closely (r = 0.92). The device also functioned well during low-flow states, but during hypothermic cardiopulmonary bypass, the correlation was only fair (r = 0.62). When nitrous oxide was present in the inspired gas, Sentorr PaO2 readings were a third lower than actual PO2 measurements, an effect corroborated by an in-vitro experiment. Directional changes of oxygen and carbon dioxide tensions were always correct in all situations. Placement of the probe in a radial artery was unsatisfactory because it significantly interfered with blood pressure measurement and resulted in inaccurate results for this patient population. The brachial artery was a satisfactory site for insertion, although attenuation of the arterial pressure tracing by the presence of a Sentorr probe resulted in systolic pressure readings that averaged 12 torr lower with mean arterial pressure readings 5 torr lower. No increase in morbidity due to use of a Sentorr probe for brachial arterial pressure monitoring could be identified. The most potentially serious complication encountered was transient loss of a palpable pulse without interruption of blood flow in one or more distal arteries after decannulation. This was observed in seven patients (four of whom had diminished distal pulses whith normal flow before cannulation).
