Osteopathic education: The link between mission and accreditation

ObjectiveThis commentary promotes the role of accreditation in meeting a school's mission.BackgroundUnderstanding the parallels between the growth of osteopathic educational institutions and the increase in educational standards over time places a historical perspective on this subject.DataThe concept of minimum competence, exceeding minimum competence, and their link to the assurance of quality in osteopathic medical education is explored. Knowing that a school's mission speaks to excellence and quality, and that the accreditation process is a way to ensure quality, mission and accreditation are therefore linked.ConclusionThrough the accreditation process, we ensure that our schools' missions are met, and we assure our students and the public that we deliver an osteopathic medical education of the highest quality.     

Technical standards for micro sensors in surgery and minimally invasive therapy

The development of medical applications is fuelled in the context of steadily growing needs and the requirement of lowering overall costs. Micro systems will have an extremely important impact on medical technology in the future. The great challenges for the wider use of micro structures in health applications are biocompatibility and mass production. Especially small and medium-sized enterprises (SMEs) need help to overcome these problems by free access to knowledge, the availability of standards and contacts to partners.     

Bioactive nutrients - Time for tolerable upper intake levels to address safety

There is increasing interest by consumers, researchers, and regulators into the roles that certain bioactive compounds, derived from plants and other natural sources, can play in health maintenance and promotion, and even prolonging a productive quality of life. Research has rapidly emerged suggesting that a wide range of compounds and mixtures in and from plants (such as fruits and vegetables, tea and cocoa) and animals (such as fish and probiotics) may exert substantial health benefits. There is interest in exploring the possibility of establishing recommended intakes or dietary guidance for certain bioactive substances to help educate consumers. A key aspect of establishing dietary guidance is the assessment of safety/toxicity of these substances. Toxicologists need to be involved in both the development of the safety framework and in the evaluation of the science to establish maximum intake/upper limits.     

Japanese standard for clinical stabilometry assessment: Current status and future directions

Stabilometry is a useful tool for examining patients with functional disorders of the vestibular system. However, measurement techniques and devices vary by country. Therefore, international standardization of stabilometry is mandatory to validate the exchange of important findings. This was advocated at the 1983 Posturography Meeting in Kyoto but has not been adopted worldwide, and each country has continued to use unique regional measurement methods. In Japan, stabilometry has widespread application in medical practice in conjunction with research into its applications. With a goal of international standardization, we present details of stabilometry measurement methods and their application in Japan, together with a brief history and potential future directions of stabilometry.

Proprioceptive neck influences modify the information about tilt direction coded by the cerebellar anterior vermis

Objective To verify whether the direction of head tilt coded by the population response of Purkinje (P) cells located in the cerebellar anterior vermis is modified by the relative position of the body with respect to the head.

Material and Methods In decerebrate cats, the responses of P cells to wobble of the whole animal were analyzed in order to compute the response vectors of the same cells to the labyrinthine input. These response vectors were used to evaluate the population response (vector) of all the recorded neurons to head tilt in specific directions.

Results When the head was aligned with the body, the direction of the population vector closely corresponded to that of head tilt. A 30° body-to-head rotation to the left or right around a C1–C2 vertical axis modified the response vectors of most of the recorded neurons, leading to reciprocal deviations of the population vector from the direction of head tilt of ≈30°.

Conclusion We propose that information from neck receptors regulates the convergence of labyrinthine signals with different spatial and temporal properties on corticocerebellar units, thus allowing the P-cell population to code the direction of body tilt.     

When Is Age Choosing Ageist Discrimination?

When the Covid‐19 pandemic reached the United States in spring 2020, many states and hospitals announced crisis standards of care plans that used age as a categorical exclusion criterion. Such age choosing was quickly flagged as discriminatory, and so some states and hospitals shifted to embedding age as a tiebreaker deeper in their plans. Different rationales were given for using age as a tiebreaker: that younger patients were more likely to survive than older patients, that saving younger patients would save more life years, and that younger patients deserved a chance to live through life's stages. We provide a critical analysis of these three rationales, noting the differences between them, and then questioning the ethical and legal justifications for such age choosing.
