Ethical dilemmas in skeletal collection utilization: Implications of the Black Lives Matter movement on the anatomical and anthropological sciences.

The Black Lives Matter (BLM) movement has brought to the public eye longstanding issues of social and racial injustice which have permeated the experiences of individuals of African ancestry in the United States and abroad for centuries. Motivated by a desire to disassemble a framework of systemic racism, the BLM movement has infiltrated numerous social and political arenas including the sciences, demanding change. The impact of the BLM movement is evident in the attention recently garnered by protests of museum skeletal collections' acquisition and handling of African/African American human remains.

Ancestry Studies in Forensic Anthropology: Back on the Frontier of Racism.

One of the parameters forensic anthropologists have traditionally estimated is ancestry, which is used in the United States as a proxy for social race. Its use is controversial because the biological race concept was debunked by scientists decades ago. However, many forensic anthropologists contend, in part, that because social race categories used by law enforcement can be predicted by cranial variation, ancestry remains a necessary parameter for estimation.

Posterior femoral cutaneous neuropathy in piriformis syndrome: A vascular hypothesis.

Piriformis syndrome is described as a neuromuscular condition which occurs when the sciatic nerve is compressed and/or irritated by the piriformis muscle. It is characterized by acute tenderness in the buttock with sciatica-like pain radiating into the posterior aspect of the thigh, leg, and foot. The neurogenic leg and foot pain experienced with this condition is consistent with involvement of the sciatic nerve.

Profiling Cycling Trauma throughout the Body with and Without Helmet Usage in a Large United States Health-care Network.

Background: This study aimed to characterize bodily injury patterns associated with helmet usage by comparing trauma sustained by helmeted and helmetless cyclists admitted to a large US health-care system.

Materials And Methods: A prospective trauma registry associated with a large regional United States health-care network was queried for bicycle injuries resulting in hospital admission over a 5-year period. Data pertaining to helmet usage, demographics, injury description (s), Abbreviated Injury Scale score, Injury Severity Score, and hospital length of stay were collected from 140 patients treated for bicycle-related injuries.

The Use of Learning and Study Strategies Inventory (LASSI) to Investigate Differences Between Low vs High Academically Performing Medical Students.

Objectives: This study examines differences in the Learning and Study Strategies Inventory (LASSI) 10-subscale scores between low and high academically performing medical students relative to internal and external examinations.

Methods: The LASSI instrument was administered to 180 medical students from three classes (2016, 2017, and 2018). To measure the strength of association between LASSI 10-subscale scores and performance on overall biomedical sciences and the United States Medical Licensing Examination (USMLE) Step 1, Pearson product-moment correlation analyses were performed.

Utilizing Medical Students as Internal Assets to Enhance Gross Anatomy Laboratory Learning.

Identification of cadaveric structures during anatomy summative practical examinations is a challenge for first-year medical students. To assist in cultivating this skill, we offered 12 formative laboratory activities (anatomy boot camps [ABCs]) that approximated the summative practical examination format using reciprocal and near-peer teaching. Students assisted in crafting the formative practical examination, then engaged in a self-review by scoring their individual answer sheets.

Learning and study strategies correlate with medical students' performance in anatomical sciences.

Much of the content delivered during medical students' preclinical years is assessed nationally by such testing as the United States Medical Licensing Examination (USMLE ) Step 1 and Comprehensive Osteopathic Medical Licensing Examination (COMPLEX-USA ) Step 1. Improvement of student study/learning strategies skills is associated with academic success in internal and external (USMLE Step 1) examinations. This research explores the strength of association between the Learning and Study Strategies Inventory (LASSI) scores and student performance in the anatomical sciences and USMLE Step 1 examinations.

Influence of edentulism on human orbit and zygomatic arch shape.

Edentulism, or tooth loss, seriously alters the appearance of the lower facial skeleton. The aim of this study was to determine if complete maxillary edentulism also impacts the curvature shape of the orbits and zygomatic arches in elderly adults. The study was conducted on 80 crania comprising two cross-sectional populations of elderly African- and European-Americans (60-80 years old).

Regional shape change in adult facial bone curvature with age.

Life expectancies have increased dramatically over the last 100 years, affording greater opportunities to study the impact of age on adult craniofacial morphology. This article employs a novel application of established geometric morphometric methods to examine shape differences in adult regional facial bone curvature with age. Three-dimensional semilandmarks representing the curvature of the orbits, zygomatic arches, nasal aperture, and maxillary alveolar process were collected from a cross-sectional cranial sample of mixed sex and ancestry (male and female; African- and European-American), partitioned into three age groups (young adult = 18-39; middle-aged = 40-59 years; and elderly = 60+ years).

Craniofacial growth, maturation, and change: teens to midadulthood.

Despite the attainment of several adult cranial dimensions relatively early in childhood, skeletal maturity and, by consequence, adult form are typically defined by the eruption of the third molars around 17 years of age. This in turn serves as the division between subadults and adults, which is then applied to population studies of biological variation. Specifically, comparative data sets of adult measurements are not directly applied to individuals who do not have complete skeletal growth, as it is believed that the confounding effects of allometry may skew the results.
