RESUMO

OBJECTIVES: In this rapidly changing electronic era, we implemented a study to define age dependent variations in access and use of internet and electronic devices in the exchange of healthcare related information (HRI) and coordination of clinical care (CCC) among elderly patients with cancer. MATERIALS AND METHODS: Data was collected through independently completed surveys after obtaining IRB approval in a single institution cancer center over a 4-month period. Questions regarding internet access and use of electronic media to obtain health information and coordinate care were distributed. The sample was divided in two groups based upon the World Health Organization (WHO) definition of geriatric patients: <65 y/o (group A) and ≥65 y/o (group B). RESULTS: One hundred and twenty-six surveys were analyzed with 70 patients in group A and 56 patients in group B. Access to the internet and use of email was higher in the group A (77% and 71%) vs. group B (36% and 33%, p < 0.001). The younger group felt more comfortable using the internet when compared to the older group (70% vs. 40%, p = 0.01). Patients in group B demonstrated a strong preference for paper copy based HRI and phone calls to CCC than text messages or emails (73% and 95%, p < 0.001). A transition zone between the ages of 65 and 70 years was defined to identify patients with increased reluctance to use internet and electronic devices to exchange HRI and CCC. CONCLUSION: The data supports that there is an age-defined underutilization of internet and electronic devices to exchange HRI and CCC. Characterization of this age-dependent transition zone will enable clinicians to identify patients who may not interface well with electronic communication strategies, and to improve delivery of HRI and CCC for the elderly.

RESUMO

Fostering radiology research among medical students can enhance a student's interest and understanding of radiology and research. It increases the academic productivity of the mentor and the department. Radiology faculty and departments should actively seek to recruit and engage students in research. Once involved, students benefit greatly from being given clear responsibility, close supervision, timely feedback, and a degree of autonomy. At the heart of the student research process is the crucial mentor-mentee relationship, and mentors should be cognizant of their vital role and methods of encouraging and enhancing this relationship. Ultimately, the advancement of the field of radiology depends on constant innovation and improvement. Radiology research by medical students fuels both innovation and the development of future academic radiologists and physician-scientists, helping to secure future growth for our field.

RESUMO

The National Institutes of Health's Mammalian Gene Collection (MGC) project was designed to generate and sequence a publicly accessible cDNA resource containing a complete open reading frame (ORF) for every human and mouse gene. The project initially used a random strategy to select clones from a large number of cDNA libraries from diverse tissues. Candidate clones were chosen based on 5'-EST sequences, and then fully sequenced to high accuracy and analyzed by algorithms developed for this project. Currently, more than 11,000 human and 10,000 mouse genes are represented in MGC by at least one clone with a full ORF. The random selection approach is now reaching a saturation point, and a transition to protocols targeted at the missing transcripts is now required to complete the mouse and human collections. Comparison of the sequence of the MGC clones to reference genome sequences reveals that most cDNA clones are of very high sequence quality, although it is likely that some cDNAs may carry missense variants as a consequence of experimental artifact, such as PCR, cloning, or reverse transcriptase errors. Recently, a rat cDNA component was added to the project, and ongoing frog (Xenopus) and zebrafish (Danio) cDNA projects were expanded to take advantage of the high-throughput MGC pipeline.

RESUMO

OBJECTIVE: This anatomical cadaver study was intended to incrementally determine the precise relationship between the alar rim skin margin and the caudal aspect of the lateral crus of the nose. The second intention was to preliminarily test the hypothesis of sexual dimorphism in the lateral crura size and of right to left asymmetry of the lateral crura in the same individual. STUDY DESIGN: Demographic information of 39 Caucasian cadavers was collected. Dissection of 28 unilateral and 11 bilateral noses included the removal of all of the soft tissue from the lateral surface of lateral crura cartilages. The distance from the caudal edge of the lateral crus to the alar margin was measured beginning at the junction of the middle and lateral crura moving posteriorly. The lateral crus was then completely dissected out from the remaining surrounding soft tissue for measurement of the length, height, and thickness. RESULTS: Comparison of the cartilage dimensions between the sexes showed significant differences between the length, height, and thickness of the cartilages. The distance between the caudal aspect of the lateral crus and alar skin margin was less than 6.7 mm on average for the anterior 15 mm of the lateral crus. Comparison for intraindividual right to left asymmetry showed significant differences in 3 infracartilaginous-alar skin margin distance measurements and in cartilage length and height. CONCLUSION: The marginal incision can be close to the alar skin margin in the first 15 mm. Right to left intraindividual asymmetry in the first 20 mm was significant. Intraindividual right to left asymmetry was significant in the lateral crura length and height. Sexual dimorphism in the lateral crura length, height, and thickness was observed.
