PURPOSE: Optical see-through head-mounted displays (OST-HMD) feature an unhindered and instantaneous view of the surgery site and can enable a mixed reality experience for surgeons during procedures. In this paper, we present a systematic approach to identify the criteria for evaluation of OST-HMD technologies for specific clinical scenarios, which benefit from using an object-anchored 2D-display visualizing medical information. METHODS: Criteria for evaluating the performance of OST-HMDs for visualization of medical information and its usage are identified and proposed...

PURPOSE: Many researchers have addressed the potential effects of hyperthermia and dehydration on cognition, often revealing contradictory outcomes. A possible reason for this inconsistency is that experiments may have been inadequately designed for such effects. In this study, the impact of hyperthermia, dehydration and their combination on cognition were evaluated in eight young males, after accounting for a range of experimental limitations. METHODS: Passive heating and thermal clamping at two mean body temperatures (36...

Background Essential nursing skills for safe practice are not limited to technical skills, but include abilities for determining salience among clinical data within dynamic practice environments, demonstrating clinical judgment and reasoning, problem-solving abilities, and teamwork competence. Effective instructional methods are needed to prepare new nurses for entry-to-practice in contemporary healthcare settings. Method This mixed-methods descriptive study explored self-reported perceptions of a process to self-record videos for psychomotor skill performance evaluation in a convenience sample of 102 pre-licensure students...

BACKGROUND: Brazil has a strict drinking and driving law known as the Brazilian "Dry Law". The aim of the present study was to investigate characteristics associated with the breaking of the Brazilian traffic law, on drinking and driving, at nightclub exit among a representative sample of nightclub patrons in the city of São Paulo, Brazil. METHODS: Portal survey realized with a two-stage cluster sampling survey design to collect data from 2422 patrons at the entrance and 1822 patrons at the exit of 31 nightclubs in the city of São Paulo, Brazil...

The purpose of this paper is to share lessons learned from a collaborative, community-informed mixed-methods approach to adapting an evidence-based intervention to meet the needs of Latinos with chronic disease and minor depression and their family members. Mixed-methods informed by community-based participatory research (CBPR) were employed to triangulate multiple stakeholders' perceptions of facilitators and barriers of implementing the adapted intervention in community settings. Community partners provided an insider perspective to overcome methodological challenges...

The "organic" claim explicitly informs consumers about the food production method. Yet, based on this claim, people often infer unrelated food attributes. The current research examined whether the perceived advantage of organic over conventional food generalizes across different organic food types. Compared to whole organic foods, processed organic foods are less available, familiar and prototypical of the organic food category. In two studies (combined N = 258) we investigated how both organic foods types were perceived in healthfulness, taste and caloric content when compared to their conventional alternatives...

While recent studies in adults have demonstrated the existence of a neural mechanism for a visual sense of number, little is known about its development and whether such a mechanism exists at young ages. In the current study, I introduce a novel steady-state visual evoked potential (SSVEP) technique to objectively quantify early visual cortical sensitivity to numerical and non-numerical magnitudes of a dot array. I then examine this neural sensitivity to numerical magnitude in children between three and ten years of age and in college students...

OBJECTIVE: The study aimed to review the prevalence of self-reported voice disorders in singers. STUDY DESIGN: The study is a systematic review and meta-analysis. METHODS: A systematic review of five major scientific databases was conducted. An extensive search strategy was used considering the rules of each database. Original articles were included only if they had data related to self-perception of dysphonia in the past. Furthermore, heterogeneity and its relative significance were assessed...

Intraductal carcinoma of the prostate (IDC-P) is associated with poor prognosis. While it is often regarded as a rare pathology, the prevalence of IDC-P remains unclear, with variable reports from small and disparate patient populations. To determine how common IDC-P is across the spectrum of prostate cancer, we conducted a systematic review correlating IDC-P prevalence with prostate cancer risk. Electronic searches of the OVID Medline, PubMed, and Scopus literature databases identified 38 patient cohorts in 24 articles, which were divided between four prostate cancer risk categories (low, moderate, high, and recurrent or metastatic disease)...

INTRODUCTION: Burnout among emergency medical practitioners and personnel negatively affects career satisfaction and job performance and can lead to mental health issues, including anxiety, depression, and suicide. PURPOSE: This study investigated the relationship between the perceptions of burnout and job satisfaction of those working in two different hospital's emergency departments assessing the effect of burnout dimensions and additional factors (age, position, marital status, annual income, employment type, gender, patient encounters, and household economic well-being) on job satisfaction...

This paper examines the costs and benefits of selecting for polled dairy heifers versus traditional dehorning practices. Stochastic budgets were developed to analyze the expected costs (EC) associated with polled dairy genetics. The economic assessment was expanded beyond on-farm cash costs by incorporating cost and benefit estimates to generate industry-wide discussion, and preliminary economic evaluations, surrounding the public acceptance and attitude toward polled genetics versus dehorning calves. Triangular distributions, commonly used to represent distributions with limited data, were used to represent labor costs for dehorning, the likelihood of treatment of calf, and the cost of veterinary treatment...

Schizophrenia patients have well-established deficits in facial emotion perception, which contribute to their poor social functioning. A number of studies have related these deficits to a differential dysfunction in the magnocellular (M) versus parvocellular (P) visual pathway. We assessed 35 schizophrenia patients and 35 healthy individuals on an emotion identification task, in which facial stimuli were either unaltered (broad spatial frequency, BSF) or manipulated to contain only high (HSF) or low (LSF) spatial frequencies, thereby respectively biasing the visual system toward the P- or M- pathways...

Reduced physical activity is a known risk factor for many illnesses. Research in adolescent populations found increased physical activity levels improves objective health outcomes, but there is conflicting evidence regarding the relationship between physical activity levels and self-reported health status. To synthesise current evidence on the association between physical activity and self-reported health status in adolescents. Secondary objectives are to assess whether the relationship is dose dependant, and the appropriateness of WHO recommendations on adolescents' physical activity...

Objective. : Low-dose local anesthetic is often used in cervical interlaminar epidural steroid injections (CIESI), yet its effect on upper extremity strength has not been studied. The presence of consequent weakness has potential implications for postprocedure safety. This study aimed to determine whether low-dose lidocaine in a C7-T1 CIESI causes objective weakness. Design. : Prospective case series. Setting. : Academic pain center...

Introduction: Weight gain and concerns about weight can influence a smoker's ability to successfully quit, and young adults are a subgroup of smokers who are particularly concerned about the impact of quitting on their body weight. This study explored the associations between body mass index (BMI), weight perceptions, and smoking status among young adults. Methods: The sample consisted of 4,027 young adults between the ages of 18 and 29 who participated in a randomized control trial of the National Cancer Institute's SmokefreeTXT program...
