RESUMEN
BACKGROUND: Health care providers often counsel prostate cancer patients about treatment options with medical terminology. However, studies have demonstrated a severe lack of comprehension of these terms, particularly in underserved populations. It was hypothesized that a video-based educational tool would significantly improve the understanding of key terms related to prostate health in a predominantly lower literacy population. METHODS: A software application was developed by various experts, including urologists and human-computer interaction specialists, to serve as a video-based educational tool emphasizing narrated animations to promote understanding of terms related to urinary, bowel, and sexual function. This application was viewed by patients recruited from 2 low-income safety net clinics, where a previously developed survey was administered to assess pre- and postintervention levels of comprehension. RESULTS: Fifty-six patients with a mean literacy level of 7th to 8th grade completed the study. Patients achieved statistically significant improvements in comprehension for the majority of the terms after the video intervention, with notable improvements including the terms incontinence (from 14% to 50%), bowels (from 14% to 46%), and impotence (from 58% to 84%). Patients demonstrated significant gains in their understanding of the function of the prostate (from 11% to 30%) and in their ability to locate the prostate on anatomic drawings (from 50% to 82%). CONCLUSIONS: This video-based educational tool is an effective method for overcoming the severe lack of comprehension of prostate health terminology among patients. The improvements achieved have the potential to enhance patient participation in shared and informed decision making and to support combined visual-audio multimedia as a promising tool for prostate cancer education.

BACKGROUND: Patients diagnosed with prostate cancer are often counseled about treatment options with the use of terms that are part of the "core vocabulary" of prostate cancer. It is hypothesized that predominantly lower literacy patients would demonstrate a severe lack of comprehension of prostate cancer terms, thus validating the findings of a previous single-institution study. METHODS: A previously developed survey was used to evaluate understanding of terms related to urinary, bowel, and sexual function. The survey was administered by trained evaluators at 2 safety net clinics that provide care for low-income, predominantly African American patients. Comprehension was assessed using semiqualitative methods coded by 2 independent investigators. Literacy and numeracy were also evaluated. RESULTS: Among 109 patients who completed the study, only 5% understood the function of the prostate, and 15%, 29%, and 32% understood the terms "incontinence," "urinary function," and "bowel habits," respectively. Lower levels of comprehension were observed for compound words, such as "vaginal intercourse" (58%), versus single words such as "intercourse" (95%), validating previous work. Median school level was 13 years, yet median literacy level was only ninth grade, and reading level was significantly correlated with comprehension. Only 30% of patients correctly calculated both a fraction and a percent. CONCLUSIONS: Lack of comprehension of prostate health terminology is pronounced in this patient population and may be widespread. This lack of comprehension potentially limits the ability of patients to participate in informed decision-making. These results validate the findings of previous studies and supports a continued need for refined methods of prostate cancer education.

Distraction osteogenesis (DO) of the craniofacial skeleton has become an effective technique for the treatment of both nonsyndromic and syndromic conditions. The advent of craniofacial DO has allowed for earlier intervention in pediatric patients with less complication risk and morbidity compared to traditional techniques. In this review, we will discuss current application and technique for craniofacial DO by anatomical region and explore future applications in craniofacial surgery.
RESUMEN
Effective management of pediatric craniofacial tumors requires coordinated input from medical, oncologic, and surgical specialties. Reconstructive algorithms must consider limitations in pediatric donor tissue and account for future growth and development. Immediate reconstruction is often focused on filling dead space, protecting underlying structures, and ensuring skeletal symmetry. Staged reconstruction occurs after the patient has reached skeletal maturity and is focused on restoring permanent dentition. Reconstructive options vary depending on the location, size, and composition of resected tissue. Virtual surgical planning (VSP) reduces the complexity of pediatric craniofacial reconstruction and ensures more predictable outcomes.
RESUMEN
The novel coronavirus caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has reached more than 160 countries and has been declared a pandemic. SARS-CoV-2 infects host cells by binding to the angiotensin-converting enzyme 2 (ACE-2) surface receptor via the spike (S) receptor-binding protein (RBD) on the virus envelope. Global data on a similar infectious disease spread by SARS-CoV-1 in 2002 indicated improved stability of the virus at lower temperatures facilitating its high transmission in the community during colder months (December-February). Seasonal viral transmissions are strongly modulated by temperatures, which can impact viral trafficking into host cells; however, an experimental study of temperature-dependent activity of SARS-CoV-2 is still lacking. We mimicked SARS-CoV-2 with polymer beads coated with the SARS-CoV-2 S protein to study the effect of seasonal temperatures on the binding of virus-mimicking nanospheres to lung epithelia. The presence of the S protein RBD on nanosphere surfaces led to binding by Calu-3 airway epithelial cells via the ACE-2 receptor. Calu-3 and control fibroblast cells with S-RBD-coated nanospheres were incubated at 33 and 37 °C to mimic temperature fluctuations in the host respiratory tract, and we found no temperature dependence in contrast to nonspecific binding of bovine serum ablumin-coated nanospheres. Moreover, the ambient temperature changes from 4 to 40 °C had no effect on S-RBD-ACE-2 ligand-receptor binding and minimal effect on the S-RBD protein structure (up to 40 °C), though protein denaturing occurred at 51 °C. Our results suggest that ambient temperatures from 4 to 40 °C have little effect on the SARS-CoV-2-ACE-2 interaction in agreement with the infection data currently reported.

BACKGROUND: Duty hour restrictions for resident physicians have led to radical changes in graduate medical education, including a shift to more night float rotations. These rotations have been viewed by residents as predominantly service focused with little opportunity for formalized education. OBJECTIVE: To develop and deliver a resident-driven, nocturnal curriculum to enhance the educational content and value of night float rotations. METHODS: The Hospital of the University of Pennsylvania is a 695-bed, tertiary care academic medical center. Upper-level internal medicine residents developed and peer-reviewed case-based scripts designed to be delivered in 15- to 20-minute teaching sessions. We evaluated the quality of teaching using anonymous, free-response surveys. RESULTS: Twenty-four scripts were developed that explored the differential diagnoses, diagnostic pitfalls, and management of clinical problems that interns frequently encounter on night float rotations. Of 83 eligible residents, 45 (54%) responded to the survey. Teaching occurred an average of 4 nights per week and was uniformly viewed as high yield and topical by night float interns. CONCLUSIONS: A resident-driven, nocturnal curriculum was implemented through the use of case-based teaching scripts, allowing for delivery of a standardized curriculum that capitalizes on the teaching opportunities afforded by the night shift. This intervention may serve as a model for nocturnal education in other departments and institutions.
