Craniofacial Injuries Seen With the Introduction of Bicycle-Share Electric Scooters in an Urban Setting.

PURPOSE: Standing electric scooters (e-scooters) are rapidly becoming popular modes of transportation in many urban areas across the United States. However, this increase in popularity has resulted in an increase in traumatic injuries associated with these modes of expedient travel. The purpose of the present study was to determine the types of craniofacial trauma directly related to e-scooter use in a major urban center (Dallas, TX). MATERIALS AND METHODS: We performed a retrospective case series and examined the medical records of the patients who had presented to the emergency department (ED) for trauma related to e-scooter use. Descriptive statistics were calculated for all variables on patient presentation, including incident notes and patient interviews, demographic information, diagnostic tests, trauma (ie, location, type, severity), treatment (ie, type, admission, outpatient referral, follow-up data), and contributing factors (ie, reported or detected alcohol use, use of protective equipment). RESULTS: A total of 90 patients (56 males, 34 females; mean age, 31.8 years) had presented with scooter-related trauma to the ED during the first 7 months of scooters after their introduction to the metropolitan area. A total of 52 admissions (58% of all admissions) involved injuries of the head and face. The patients had presented with a myriad of craniofacial trauma, ranging from abrasions, lacerations, and concussions to intracranial hemorrhage and Le Fort II and III fractures. Of the 52 craniofacial injuries, 30 (58%) were considered severe (ie, fracture, internal hemorrhage, concussion, loss of consciousness), and 22 (42%) were considered minor (ie, lacerations, contusion, abrasion, dental). Alcohol use had been involved in 18% of all scooter-related trauma admissions, and no rider had reported wearing a helmet. CONCLUSIONS: Injuries to the head and face were commonly found with e-scooter admissions in this sample, and the high prevalence of extremity injuries suggested that patients were breaking their fall during the crash. Craniofacial trauma related to e-scooter use could be significantly reduced by the wearing of a protective helmet.

Sprint speed is unaffected by dietary manipulation in trained male Anolis carolinensis lizards.

Performance traits are energetically costly, and their expression and use can drive trade-offs with other energetically costly life-history traits. However, different performance traits incur distinct costs and may be sensitive to both resource limitation and to the types of resources that are accrued. Protein is likely to be especially important for supporting burst performance traits such as sprint speed, but the effect of varying diet composition on sprint training in lizards, an emerging model system for exercise training, is unknown. We tested the hypothesis that the response to sprint training is sensitive to both the type and amount of resources in Anolis carolinensis. We also measured bite force across all treatments as a control whole-organism performance trait that should be unaffected by locomotor training. Both mass and bite force are reduced by dietary restriction over the course of 9 weeks of sprint training, but sprint speed is unaffected by either training or dietary restriction relative to controls. Furthermore, protein supplementation does not rescue a decline in either mass or bite force in trained, diet-restricted males. These results contrast with those for endurance training, and suggest that sprint speed is more canalized than either endurance or bite force in green anoles.

Educational interventions for physical activity among Brazilian adults: systematic review / Intervenções educativas para atividade física em adultos brasileiros: revisão sistemática

ABSTRACT OBJECTIVE To summarize the main evidence from educational interventions designed to increase levels of physical activity (PA) among Brazilian adults. METHODS Systematic review of intervention studies carried out in Brazil that implemented educational components aimed at promoting increased levels of PA among adult populations (18 to 65 years old). In October 2020, systematic searches were conducted in six databases, and in the reference lists of the assessed studies. RESULTS Of the initial 2,511 studies, nine were included in the synthesis. Samples with specific characteristics (such as social vulnerability, physical inactivity, and overweight or obesity) were observed, with a greater number of women. Five interventions (55.6%) occurred in primary healthcare settings (PHC) of the Brazilian Unified Health System (SUS). Only four studies (44.4%) described the pedagogical frameworks structuring the educational approaches, among which counseling was the most used strategy, such as those carried out through face-to-face meetings, home visits, lectures, and phone calls (n = 8; 88.9%). Positive results were observed in three different indicators: increase in weekly PA volume (n = 4); increase in leisure-time PA rate (n = 1); and increase in the proportion of women classified as "very active/active" (n = 1). Given the sampling specificities, the domain "participant selection" showed a high number of interventions with high risk of bias. CONCLUSIONS Educational approaches engendered some positive effects on different PA indicators, notably counseling as the main strategy used and approaches involving other health themes, such as nutrition and stress. However, considering the several determinants of PA in Brazil, future interventions should be conducted in different locations of Brazil in order to evaluate, in a broader way, their implementation processes and articulation with the many professionals working in PHC.

RESUMO OBJETIVO Sumarizar as principais evidências de intervenções educativas delineadas para o aumento dos níveis de atividade física (AF) em adultos brasileiros. MÉTODOS Revisão sistemática de estudos de intervenção conduzidos no Brasil, que implementaram componentes educativos com a finalidade de promover o aumento dos níveis de AF em populações de adultos (18 a 65 anos). Em outubro de 2020, buscas sistemáticas foram conduzidas em seis bases de dados e nas listas de referências dos artigos avaliados. RESULTADOS Dos 2.511 artigos iniciais, nove compuseram a síntese. Foram observadas amostras com características específicas (como vulnerabilidade social, inatividade física e sobrepeso ou obesidade), com maior número de mulheres. Cinco intervenções (55,6%) ocorreram nos cenários da atenção primária à saúde (APS) do Sistema Único de Saúde (SUS). Apenas em quatro estudos (44,4%) houve descrição dos referenciais pedagógicos estruturantes das abordagens educativas, dentro os quais o aconselhamento se configurou como a estratégia mais utilizada, como aquelas realizadas por meio de encontros presenciais, visitas domiciliares, palestras e chamadas telefônicas (n = 8; 88,9%). Resultados positivos foram observados em três distintos indicadores: aumento do volume semanal de AF (n = 4); aumento do índice de AF no lazer (n = 1); e aumento da proporção de mulheres classificadas como "muito ativas/ativas" (n = 1). Visto as especificidades amostrais, o domínio "seleção dos participantes" apresentou elevado número de intervenções com alto risco de viés. CONCLUSÕES As abordagens educativas produziram alguns efeitos positivos em distintos indicadores de AF, destacando-se o aconselhamento como principal estratégia utilizada e as abordagens que envolveram outras temáticas de saúde, como nutrição e estresse. Contudo, frente aos diversos determinantes da AF no Brasil, é importante que futuras intervenções sejam conduzidas em variadas localizações do país, de forma que avaliem, de maneira mais ampla, seus processos de implementação e articulação com os distintos profissionais que atuam na APS.

Clinicopathologic conference: trismus following dental treatment.

Myositis ossificans traumatica is a rare clinical entity in the maxillofacial region. We present a case of myositis ossificans traumatica of the temporalis muscle following dental treatment in the form of a clinicopathologic conference. A review of the literature supporting our findings is provided.
