Space radiation research with heavy ions at HIMAC.

The HIMAC (Heavy Ion Medical Accelerator in Chiba) was originally designed principally for carbon ion therapy, but heavy ion research projects in medicine, physics, chemistry and biology have been conducted under a collaborative research framework since 1994. One major application is space radiation research. The radiation in space of greatest interest for human space exploration consists of energetic protons and heavy ions which can affect the health of space crew and lead to the failure of electronic devices.

Using tele-paramedicine to conduct in-home fall risk reduction after emergency department discharge: Preliminary data.

Background: Older adults discharged from our emergency department (ED) do not receive comprehensive fall risk evaluations. We conducted a quality improvement project using an existing Community Tele-Paramedicine (CTP) program to perform in-home fall risk assessment and mitigation after ED discharge.

Methods: High falls-risk patients, as defined by STEADI score >4, were referred for a CTP home visit by community paramedics supervised virtually by emergency physicians.

Student, Staff and Faculty Experience with a Medical School Racial and Sociopolitical Trauma Protocol: A Mixed Methods Study.

 Medical students experience racial and sociopolitical trauma that disrupts their learning and wellbeing.  University of California, San Francisco (UCSF) School of Medicine students advocated for a systems approach to responding to traumatic events. Students partnered with educators to introduce an innovative protocol that affords short-term flexibility in curricular expectations (e.

Secondary proton buildup in space radiation shielding.

The risk posed by prolonged exposure to space radiation represents a significant obstacle to long-duration human space exploration. Of the ion species present in the galactic cosmic ray spectrum, relativistic protons are the most abundant and as such are a relevant point of interest with regard to the radiation protection of space crews involved in future long-term missions to the Moon, Mars, and beyond. This work compared the shielding effectiveness of a number of standard and composite materials relevant to the design and development of future spacecraft or planetary surface habitats.
