Ultrasound imaging in medical student education: Impact on learning anatomy and physical diagnosis

Ultrasound use has expanded dramatically among the medical specialties for diagnostic and interventional purposes, due to its affordability, portability, and practicality. This imaging modality, which permits real‐time visualization of anatomic structures and relationships in vivo, holds potential for pre‐clinical instruction of students in anatomy and physical diagnosis, as well as providing a bridge to the eventual use of bedside ultrasound by clinicians to assess patients and guide invasive procedures. In many studies, but not all, improved understanding of anatomy has been demonstrated, and in others, improved accuracy in selected aspects of physical diagnosis is evident. Most students have expressed a highly favorable impression of this technology for anatomy education when surveyed. Logistic issues or obstacles to the integration of ultrasound imaging into anatomy teaching appear to be readily overcome. The enthusiasm of students and anatomists for teaching with ultrasound has led to widespread implementation of ultrasound‐based teaching initiatives in medical schools the world over, including some with integration throughout the entire curriculum; a trend that likely will continue to grow.

This study explored changes in preservice teachers’ (PSTs) nature of science pedagogical (NOSP) views and nature of science (NOS) rationales using pre- and post-course written responses as well as interview data. Through systematic analysis, themes were generated and compared to the NOS literature. Comparisons between pre- and post-course data demonstrate improved and deepened NOS views, NOSP views that are more aligned with NOS literature, and a greater number of rationales for including NOS. All participants were enrolled in the “Inquiry and Natures of Science, Technology, and Engineering” (INSTE) course. However, six participants were enrolled in INSTE as their first course in which NOS and NOSP were addressed. The other six participants were enrolled in INSTE as their second course in which NOS and NOSP were addressed, with science methods as their first course in which NOS and NOSP were addressed. By comparing participants enrolled in INSTE as their first course to those enrolled in INSTE as their second course, we observed that NOS understanding seemed to develop in a first experience alongside some NOS rationales, but NOSP views lagged for participants in INSTE as their first course. Participants enrolled in INSTE as their second course developed more robust and literature-aligned NOSP views and more multifaceted NOS rationales. Therefore, this study bolsters arguments that teachers need to receive extended NOS and NOSP instruction. 相似文献

Erythrocyte membrane protein glycosylation increase by 3.4 fold in diabetes. Insulin or sulfonylurea treatment did not reduce
the extent of glycosylation. The serum protein glycosylation was comparable in all the groups including control. Erythrocyte
membrane Na+,K+-ATPase activity decreased in the diabetics; only insulin treatment partly restored the activity. Erythrocyte membrane acetylcholinesterase
activity decreased only in the sulfonylurea treated group. Serum butyrylcholinesterase activity was relatively low in the
diabetic and insulin treated diabetic groups. The Km and Vmax of the two components of Na+,K+-ATPase from erythrocyte membranes were differently affected in the diabetic and the two treatment groups. The Vmax of acetylcholinesterase
decreased only in the sulfonylurea treated group. Diabetic states resulted in decreased Vmax of components I and II of serum
butyrylcholinesterase. In insulin-treated diabetics, component II was absent. Sulfonylurea group resembled diabetics.In vitro incubation with insulin differentially affected the Na+,K+-ATPase and serum butyrylcholinesterase activities. 相似文献

Daily urinary follicle stimulating hormone (FSH), luteinizing hormone (LH) and testosterone (T) levels were estimated in a group of 10 normal one month old male infants. Four-hourly urine samples were collected from each infant over a three months period i.e., from one month to four months of infants age. The hormonal levels were expressed as mIU of FSH, LH and ng of T per mg creatinine. The normal hormonal pattern thus obtained could be used to compare patterns obtained from pathological cases or when monitoring the effects of drugs on infants. 相似文献

Forty cases of head and neck cancer were studied for plasma superoxide dismutase, malondialdehyde and thiol levels and results
were compared with a group of forty normal healthy volunteers. Mean plasma superoxide dismutase activity was not found to
be altered while malondialdehyde concentration was significantly higher when compared with the control group. On the other
hand, mean thiol level was significantly lowered. The data suggests increased level of oxidative stress in patients with head
and neck cancer. 相似文献

This study used population-representative data to examine associations of risk and protective factor patterns among Alaska Native/American Indian (AN/AI; N = 592) and non-Native (N = 1,018) children with maternal and child outcomes at age 3 years. Among AN/AI children, a high risk/moderate protection class was associated with child developmental risk and mothers being less likely to feel comfortable asking for help or knowing where to go for parenting information compared to a low socioeconomic status/high protection class. Among non-Native children, a moderate risk/high protection class was associated with child developmental risk and mothers being less likely to feel comfortable asking for help compared to a low risk/high protection class. Results provide insight on the intersection of risk and protective factors among Alaska families. 相似文献

The transition between school or college and higher education can be a challenging time for a student. Schools, colleges and universities work together in a number of ways in order to try and ease this process. However, many students still find their first-year experience difficult to adjust to, which can impact on their own development and achievement. This article documents critical reflections on a case study of a teaching, learning and research partnership currently being undertaken between a secondary school where students are taught AS and A Level psychology and a department of psychology in a post-1992 university in England. Drawing upon a social constructivist framework together with Healey’s model of the link between research and teaching, the aims of this study were to explore how undergraduate dissertation students can work with AS and A Level students on their dissertation projects. The study showed that the AS and A Level students found it an enjoyable practical experience, which they felt enhanced their understanding of university studies. The dissertation students found that the experience might be useful for postgraduate studies and future employment. This article highlights the benefits of the process but also the challenges for those involved, particularly if it was to be conducted on a larger scale. 相似文献
