Three-dimensional analysis of facial morphology.

OBJECTIVES: The objectives of this study were to evaluate sexual dimorphism for facial features within Chinese and African American populations and to compare the facial morphology by sex between these 2 populations. MATERIALS AND METHODS: Three-dimensional facial images were acquired by using the portable 3dMDface System, which captured 189 subjects from 2 population groups of Chinese (n = 72) and African American (n = 117). Each population was categorized into male and female groups for evaluation. All subjects in the groups were aged between 18 and 30 years and had no apparent facial anomalies. A total of 23 anthropometric landmarks were identified on the three-dimensional faces of each subject. Twenty-one measurements in 4 regions, including 19 distances and 2 angles, were not only calculated but also compared within and between the Chinese and African American populations. The Student's t-test was used to analyze each data set obtained within each subgroup. RESULTS: Distinct facial differences were presented between the examined subgroups. When comparing the sex differences of facial morphology in the Chinese population, significant differences were noted in 71.43% of the parameters calculated, and the same proportion was found in the African American group. The facial morphologic differences between the Chinese and African American populations were evaluated by sex. The proportion of significant differences in the parameters calculated was 90.48% for females and 95.24% for males between the 2 populations. The African American population had a more convex profile and greater face width than those of the Chinese population. CONCLUSIONS: Sexual dimorphism for facial features was presented in both the Chinese and African American populations. In addition, there were significant differences in facial morphology between these 2 populations.

A 3D analysis of Caucasian and African American facial morphologies in a US population.

INTRODUCTION: This study aimed to compare facial morphologies of an adult African-American population to an adult Caucasian-American population using three-dimensional (3D) surface imaging. MATERIALS AND METHODS: The images were captured using a stereophotogrammetric system (3dMDface(TM) system). Subjects were aged 19-30 years, with normal body mass index and no gross craniofacial anomalies. Images were aligned and combined using RF6 Plus Pack 2 software to produce a male and female facial average for each population. The averages were superimposed and the differences were assessed. RESULTS: The most distinct differences were in the forehead, alar base and perioricular regions. The average difference between African-American and Caucasian-American females was 1·18±0·98 mm. The African-American females had a broader face, wider alar base and more protrusive lips. The Caucasian-American females had a more prominent chin, malar region and lower forehead. The average difference between African-American and Caucasian-American males was 1·11±1·04 mm. The African-American males had a more prominent upper forehead and periocular region, wider alar base and more protrusive lips. No notable difference occurred between chin points of the two male populations. CONCLUSIONS: Average faces were created from 3D photographs, and the facial morphological differences between populations and genders were compared. African-American males had a more prominent upper forehead and periocular region, wider alar base and more protrusive lips. Caucasian-American males showed a more prominent nasal tip and malar area. African-American females had broader face, wider alar base and more protrusive lips. Caucasian-American females showed a more prominent chin point, malar region and lower forehead.

Integration of a Simulation Curriculum Across Semesters in an Acute Care Pediatric Nurse Practitioner Program.

INTRODUCTION: Simulation is a common strategy for health care education. Research regarding simulation for nurse practitioner education is sparse. This paper describes the integration of a nine simulation session curriculum into a nurse practitioner program, including motivating factors, process description, and lessons learned. RESULTS: Students report high satisfaction and improved perception of confidence and competence of knowledge, skills, and performance. DISCUSSION: Integrated learning experiences and outcomes that span an educational program are needed in thetransition to competency-based education. This description serves as a guide for other programs seeking to incorporate simulation-based education.

Living the Manatt report: Advancing the future of nursing through joint academic appointments.

In 2016, the American Association of Colleges of Nursing published the Manatt Report which outlines recommendations to address the future of academic nursing. This report asserts that in order to influence the direction of healthcare, academic nursing needs to partner with academic health centers in leadership positions, embrace current clinical practice, and prioritize research. The following paper details the successful implementation of joint academic appointments between a college of nursing and a medical college. Joint appointments have formalized the role of clinician-educator, brought current clinical knowledge to academia, and allowed for protected academic time that is focused on enhancing the nursing curriculum. The development of joint appointments must be approached in a structured fashion ensuring a symbiotic relationship for all parties. This arrangement validates the commitment of both organizations to the education of future providers within the interdisciplinary team.

The Development of a Long Peripheral Catheter Program at a Large Pediatric Academic Center: A Pilot Study.

OBJECTIVES: The purpose of this study was to evaluate the feasibility of a new long peripheral catheter (LPC) program at a large academic center in an effort to reduce the use of peripherally inserted central catheters (PICCs) and their related complications. METHODS: The pilot participants were hospitalized children, age >2 years, with a need for noncentral intravenous access for 2 to 29 days, or laboratory blood draw >5 times per day. Patients expected to discharge with intravenous access were excluded. Included in the pilot program development were a literature review, 1-year baseline data analysis, and program design and implementation. A multidisciplinary committee developed and implemented the program from December 2018 to September 2019. LPCs were placed from August to September 2019. RESULTS: Regarding the baseline data, between July 2018 and June 2019, 584 PICCs were placed in 461 patients. Of these, 139 PICCs (24%) did not meet requirements necessitating central access and, potentially, could have been avoided if an LPC alternative were available at the time. For the LPC pilot program, 20 LPCs were placed in 19 patients. The median age was 11 (interquartile range of 7-15). The insertion success rate was 83%. There were no serious complications, such as venous thrombosis or catheter-related bloodstream infection. The total rate of minor complications was 35%: the rate of occlusions was 10% (n = 2), and the rate of dislodgement was 25% (n = 5). The catheter failure rate was 74 per 1000 catheter-days. The mean line duration was 6 days. CONCLUSIONS: There is a role for LPCs in hospitalized children requiring durable vascular access. Multispecialty designed pilot implementation of an LPC program was successful at an academic pediatric hospital.
