Resident Physicians' Knowledge of Emergency Medical Services: A Comparison Between Emergency Medicine and Non-Emergency Medicine Resident Physicians.

Background and objective Emergency medical services (EMS) are often assumed to only involve bringing patients to physicians for treatment in the emergency department. However, EMS staff are also responsible for responding to physicians in the primary care setting when medical emergencies arise. While emergency medicine (EM) residents are exposed to EMS as part of their curriculum, little is known about the knowledge of other resident physicians who may interact with EMS. In light of this, we conducted this study to address the scarcity of data related to this topic. Methods A quantitative cross-sectional knowledge assessment was conducted among resident physicians in emergency medicine, internal medicine, family medicine, pediatric, and combined medicine and pediatric residencies at the Penn State Milton S. Hershey Medical Center. Results Eighteen EM residents and 26 non-EM residents completed the assessment. The EM residents had a higher average score when compared to non-emergency medicine residents (69.2% vs. 53.8%, p=0.0012). Conclusion Variations in scores between EM and other specialties that interact with EMS highlight the need for further training and familiarization related to EMS for residents in non-EM specialties.

Multifilament Collagen Fiber Bundles with Tendon-like Structure and Mechanical Performance.

Collagen multifilament bundles comprised of thousands of monofilaments are prepared by multipin contact drawing of an entangled polymer solution consisting of collagen and poly(ethylene oxide) (PEO). The multifilament bundles are hydrated in graded concentrations of PEO and phosphate buffered saline (PBS) to promote assembly of collagen fibrils within each monofilament while preserving the structure of the multifilament bundle. Multiscale structural characterization reveals that the hydrated multifilament bundle contains properly folded collagen molecules packed in collagen fibrils containing microfibrils, staggered by exactly one-sixth of the microfibril D-band spacing to produce a periodicity of 11 nm. Sequence analysis predicts that in this structure, phenylalanine residues are close enough within and between microfibrils to become ultraviolet C (UVC) crosslinked. In agreement with this analysis, the ultimate tensile strength (UTS) and Young's modulus of the hydrated collagen multifilament bundles crosslinked by UVC radiation increase nonlinearly with total UVC energy to reach values in the range of native tendons without damage to the collagen molecules. This fabrication method recapitulates the structure of a tendon across multiple length scales and offers tunability in tensile properties using only collagen molecules and no other chemical additives in addition to PEO, which is almost entirely removed during the hydration process.

Fathers' psychological responses to pediatric cancer-induced financial distress.

BACKGROUND: To describe how pediatric cancer-induced financial distress and perceptions of their social role affected fathers' psychological responses to this distress, and quality of life (QOL) for them and their families. PROCEDURE: We analyzed father-only responses from a larger cross-sectional survey study about the impact of pediatric cancer-induced financial distress on parents. Our analytic sample was n = 87 fathers who participated in the larger study. We analyzed their data using descriptive statistics and directed content analysis. RESULTS: Conflicting role responsibilities (be there for child; work to maintain income and insurance coverage) seemed to generate responses resembling characteristic posttraumatic stress symptoms in reaction to acute declines in family finances and/or the chronic stress of insufficient finances to meet financial demands, that is, financial trauma. Fathers' personal sense of not being able to adequately provide for their child with cancer and also meet their family's basic needs produced embarrassment and humiliation, which led to discomfort talking about finances; fear, persistent thoughts and anxiety about money; reduced joy; beliefs that they did not deserve to express their needs; and feeling vulnerable to repeated financial stressors. CONCLUSIONS: Pediatric cancer-induced financial burden contributed to fathers' symptom severity and burden, and QOL declines. Clinicians should develop sensitivity to the multiple ways that pediatric cancer affects individuals and families. Future research should examine the effects of pediatric cancer-induced financial burden on mothers, and develop ways to sensitively and systematically assess financial burden, associated psychological responses and declines in QOL, and intervene as indicated.
