RESUMO
For over a century, the evolution of animal play has sparked scientific curiosity. The prevalence of social play in juvenile mammals suggests that play is a beneficial behavior, potentially contributing to individual fitness. Yet evidence from wild animals supporting the long-hypothesized link between juvenile social play, adult behavior, and fitness remains limited. In Western Australia, adult male bottlenose dolphins (Tursiops aduncus) form multilevel alliances that are crucial for their reproductive success. A key adult mating behavior involves allied males using joint action to herd individual females. Juveniles of both sexes invest significant time in play that resembles adult herding-taking turns in mature male (actor) and female (receiver) roles. Using a 32-y dataset of individual-level association patterns, paternity success, and behavioral observations, we show that juvenile males with stronger social bonds are significantly more likely to engage in joint action when play-herding in actor roles. Juvenile males also monopolized the actor role and produced an adult male herding vocalization ("pops") when playing with females. Notably, males who spent more time playing in the actor role as juveniles achieved more paternities as adults. These findings not only reveal that play behavior provides male dolphins with mating skill practice years before they sexually mature but also demonstrate in a wild animal population that juvenile social play predicts adult reproductive success.

OBJECTIVES: To evaluate the association between postoperative cumulative fluid balance (FB) and development of chylothorax in neonates after cardiac surgery. DESIGN: Multicenter, retrospective cohort identified within the Neonatal and Pediatric Heart and Renal Outcomes Network (NEPHRON) Registry. SETTING: Twenty-two hospitals were involved with NEPHRON, from September 2015 to January 2018. PATIENTS: Neonates (< 30 d old) undergoing index cardiac operation with or without cardiopulmonary bypass (CPB) entered into the NEPHRON Registry. Postoperative chylothorax was defined in the Pediatric Cardiac Critical Care Consortium as lymphatic fluid in the pleural space secondary to a leak from the thoracic duct or its branches. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of the 2240 NEPHRON patients, 4% ( n = 89) were treated for chylothorax during postoperative day (POD) 2-21. Median (interquartile range [IQR]) time to diagnosis was 8 (IQR 6, 12) days. Of patients treated for chylothorax, 81 of 89 (91%) had CPB and 68 of 89 (76%) had Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery Congenital Heart Surgery 4-5 operations. On bivariate analysis, chylothorax patients had higher POD 1 FB (3.2 vs. 1.1%, p = 0.014), higher cumulative POD 2 FB (1.5 vs. -1.5%, p < 0.001), achieved negative daily FB by POD 1 less often (69% vs. 79%, p = 0.039), and had lower POD 1 urine output (1.9 vs. 3. 2 mL/kg/day, p ≤ 0.001) than those without chylothorax. We failed to identify an association between presence or absence of chylothorax and peak FB (5.2 vs. 4.9%, p = 0.9). Multivariable analysis shows that higher cumulative FB on POD 2 was associated with greater odds (odds ratio [OR], 95% CI) of chylothorax development (OR 1.5 [95% CI, 1.1-2.2]). Further multivariable analysis shows that chylothorax was independently associated with greater odds of longer durations of mechanical ventilation (OR 5.5 [95% CI, 3.7-8.0]), respiratory support (OR 4.3 [95% CI, 2.9-6.2]), use of inotropic support (OR 2.9 [95% CI, 2.0-4.3]), and longer hospital length of stay (OR 3.7 [95% CI, 2.5-5.4]). CONCLUSIONS: Chylothorax after neonatal cardiac surgery for congenital heart disease (CHD) is independently associated with greater odds of longer duration of cardiorespiratory support and hospitalization. Higher early (POD 2) cumulative FB is associated with greater odds of chylothorax. Contemporary, prospective studies are needed to assess whether early fluid mitigation strategies decrease postoperative chylothorax development.

Background Arterial tortuosity is associated with adverse events in Marfan and Loeys-Dietz syndromes but remains understudied in Vascular Ehlers-Danlos syndrome. Methods and Results Subjects with a pathogenic COL3A1 variant diagnosed at age <50 years were included from 2 institutions and the GenTAC Registry (National Registry of Genetically Triggered Thoracic Aortic Aneurysms and Cardiovascular Conditions). Height-adjusted vertebral artery tortuosity index (VTI-h) using magnetic resonance or computed tomography angiography was calculated. Associations between VTI-h and outcomes of (1) cardiovascular events (arterial dissection/rupture, aneurysm requiring intervention, stroke), or (2) hollow organ collapse/rupture at age <50 years were evaluated using receiver operator curve analysis (using outcome by age 30 years) and mixed-effects Poisson regression for incidence rate ratios. Of 65 subjects (54% male), median VTI-h was 12 (interquartile range, 8-16). Variants were missense in 46%, splice site in 31%, and null/gene deletion in 14%. Thirty-two subjects (49%) had 59 events, including 28 dissections, 5 arterial ruptures, 4 aneurysms requiring intervention, 4 strokes, 11 hollow organ ruptures, and 7 pneumothoraces. Receiver operator curve analysis suggested optimal discrimination at VTI-h ≥15.5 for cardiovascular events (sensitivity 70%, specificity 76%) and no association with noncardiovascular events (area under the curve, 0.49 [95% CI, 0.22-0.78]). By multivariable analysis, older age was associated with increased cardiovascular event rate while VTI-h ≥15.5 was not (incidence rate ratios, 1.79 [95% CI, 0.76-4.24], P=0.185). However, VTI-h ≥15.5 was associated with events among those with high-risk variants <40 years (incidence rate ratios, 4.14 [95% CI, 1.13-15.10], P=0.032), suggesting effect modification by genotype and age. Conclusions Increased arterial tortuosity is associated with a higher incidence rate of cardiovascular events in Vascular Ehlers-Danlos syndrome. Vertebral tortuosity index may be a useful biomarker for prognosis when evaluated in conjunction with genotype and age.

Individuals with bicuspid aortic valve (BAV) have historically been advised to avoid contact sports and isometric exercise for risk of increasing aortic dilation and valve disease. There is mounting evidence that current sports participation guidelines qualify children for a high rate of sports exclusion, and that this population is at increased risk of obesity. The primary aim of this study was to evaluate relationship between sports participation and aortic dilation in children with bicuspid aortic valve and secondarily the relationship between competitive sports participation and obesity. We performed a review of children between the ages of 8 and 17 years with isolated BAV followed at Oregon Health & Science University. We excluded those with other congenital heart diseases, genetic conditions, prior cardiac intervention, and inability to ambulate independently. Parents completed a phone survey detailing their child's level of daily activity and participation in competitive sports. Demographic information and most recent echo findings were collected from the electronic medical record. We found no difference between the aortic diameters of athletes vs non-athletes. We also found that sports participation and daily activity were both associated with a decreased likelihood of obesity (OR 0.24, 95% CI 0.078-0.73 and OR 0.24, 95% CI 0.081-0.71 respectively). In summary, in our sample population, competitive sports participation was associated with a decreased risk of obesity. Competitive sports participation does not appear to be associated with an increased risk of aortic dilation in our population.
RESUMO
Vascular surgical emergencies are common in vascular surgical care and require complex decision making and multidisciplinary care. They are especially challenging when they occur in patients with unique physiological characteristics, such as pediatric, pregnant, and frail patients. Among the pediatric and pregnant population, vascular emergencies are rare. This rarity challenges accurate and timely diagnosis of the vascular emergency. This landscape review summarizes these three unique populations' epidemiology and emergency vascular considerations. Understanding the epidemiology is the foundation for accurate diagnosis and subsequent management. Considering each population's unique characteristics is crucial to the emergent vascular surgical interventions decision making. Collaborative and multidisciplinary care is vital in gaining expertise in managing these special populations and achieving optimal patient outcomes.

EMILIN1 (elastin-microfibril-interface-located-protein-1) is a structural component of the elastic fiber network and localizes to the interface between the fibrillin microfibril scaffold and the elastin core. How EMILIN1 contributes to connective tissue integrity is not fully understood. Here, we report bi-allelic EMILIN1 loss-of-function variants causative for an entity combining cutis laxa, arterial tortuosity, aneurysm formation, and bone fragility, resembling autosomal-recessive cutis laxa type 1B, due to EFEMP2 (FBLN4) deficiency. In both humans and mice, absence of EMILIN1 impairs EFEMP2 extracellular matrix deposition and LOX activity resulting in impaired elastogenesis, reduced collagen crosslinking, and aberrant growth factor signaling. Collagen fiber ultrastructure and histopathology in EMILIN1- or EFEMP2-deficient skin and aorta corroborate these findings and murine Emilin1-/- femora show abnormal trabecular bone formation and strength. Altogether, EMILIN1 connects elastic fiber network with collagen fibril formation, relevant for both bone and vascular tissue homeostasis.

OBJECTIVE: Menstrual cycle-related conditions, such as dysmenorrhea and heavy bleeding, are common amongst those under 25 years. Despite having significant impact on work, education, and social activities, most do not seek medical advice, preferring to self-manage their symptoms. We aimed to determine if access to a web-based resource was a feasible and acceptable method for improving menstrual health literacy and encouraging health seeking behavior. METHODS: People were eligible to participate if they were currently living in Australia, aged 14-25 years, and had menstruated for at least 12 months. Access to the resource, comprising evidence-based information on the menstrual cycle, the Period ImPact and Pain Assessment (PIPPA) tool, and guidance on self-management options, was provided for three menstrual cycles. RESULTS: Seventy-five participants with a mean age of 20.4 years were enrolled with 56 (75%) providing pre and post measures. Recruitment rate and retention rates met pre-specified criteria for feasibility. Eighty five percent of the participants reported the web-based resource was easy to use, and 90% reported they found the information provided 'very helpful'. Just under half (48%) reported the resource changed what they thought was a 'normal' period. Forty-three percent visited their doctor regarding their menstrual symptoms during the study period, with 84% indicating that they made the appointment due to the resource; over half (56%) who visited their doctor received a referral to a gynecologist. CONCLUSION: Access to a web-based resource on menstrual health literacy was found to be acceptable and feasible to young people and may encourage health-seeking behavior.

OBJECTIVE: A standardised multi-site approach to manage paediatric post-operative chylothorax does not exist and leads to unnecessary practice variation. The Chylothorax Work Group utilised the Pediatric Critical Care Consortium infrastructure to address this gap. METHODS: Over 60 multi-disciplinary providers representing 22 centres convened virtually as a quality initiative to develop an algorithm to manage paediatric post-operative chylothorax. Agreement was objectively quantified for each recommendation in the algorithm by utilising an anonymous survey. "Consensus" was defined as ≥ 80% of responses as "agree" or "strongly agree" to a recommendation. In order to determine if the algorithm recommendations would be correctly interpreted in the clinical environment, we developed ex vivo simulations and surveyed patients who developed the algorithm and patients who did not. RESULTS: The algorithm is intended for all children (<18 years of age) within 30 days of cardiac surgery. It contains rationale for 11 central chylothorax management recommendations; diagnostic criteria and evaluation, trial of fat-modified diet, stratification by volume of daily output, timing of first-line medical therapy for "low" and "high" volume patients, and timing and duration of fat-modified diet. All recommendations achieved "consensus" (agreement >80%) by the workgroup (range 81-100%). Ex vivo simulations demonstrated good understanding by developers (range 94-100%) and non-developers (73%-100%). CONCLUSIONS: The quality improvement effort represents the first multi-site algorithm for the management of paediatric post-operative chylothorax. The algorithm includes transparent and objective measures of agreement and understanding. Agreement to the algorithm recommendations was >80%, and overall understanding was 94%.

BACKGROUND: The GenTAC (Genetically Triggered Thoracic Aortic Aneurysm and Cardiovascular Conditions) Registry enrolled patients with genetic aortopathies between 2007 and 2016. OBJECTIVES: The purpose of this study was to compare age distribution and probability of elective surgery for proximal aortic aneurysm, any dissection surgery, and cardiovascular mortality among aortopathy etiologies. METHODS: The GenTAC study had a retrospective/prospective design. Participants with bicuspid aortic valve (BAV) with aneurysm (n = 879), Marfan syndrome (MFS) (n = 861), nonsyndromic heritable thoracic aortic disease (nsHTAD) (n = 378), Turner syndrome (TS) (n = 298), vascular Ehlers-Danlos syndrome (vEDS) (n = 149), and Loeys-Dietz syndrome (LDS) (n = 121) were analyzed. RESULTS: The 25% probability of elective proximal aortic aneurysm surgery was 30 years for LDS (95% CI: 18-37 years), followed by MFS (34 years; 95% CI: 32-36 years), nsHTAD (52 years; 95% CI: 48-56 years), and BAV (55 years; 95% CI: 53-58 years). Any dissection surgery 25% probability was highest in LDS (38 years; 95% CI: 33-53 years) followed by MFS (51 years; 95% CI: 46-57 years) and nsHTAD (54 years; 95% CI: 51-61 years). BAV experienced the largest relative frequency of elective surgery to any dissection surgery (254/33 = 7.7), compared with MFS (273/112 = 2.4), LDS (35/16 = 2.2), or nsHTAD (82/76 = 1.1). With MFS as the reference population, risk of any dissection surgery or cardiovascular mortality was lowest in BAV patients (HR: 0.13; 95% CI: 0.08-0.18; HR: 0.13; 95%: CI: 0.06-0.27, respectively). The greatest risk of mortality was seen in patients with vEDS. CONCLUSIONS: Marfan and LDS cohorts demonstrate age and event profiles congruent with the current understanding of syndromic aortopathies. BAV events weigh toward elective replacement with relatively few dissection surgeries. Nonsyndromic HTAD patients experience near equal probability of dissection vs prophylactic surgery, possibly because of failure of early diagnosis.

PURPOSE: To assess the accuracy of maternal understanding of fetal cardiac defects following initial fetal counseling. METHODS: Pregnant women with a fetal diagnosis of congenital heart disease (CHD) were surveyed regarding understanding of their fetus's heart defect. The survey asked: (1) for a description of the heart condition; (2) how confident they were in the diagnosis; (3) whether their fetus would require heart surgery. Two fetal cardiologists evaluated the maternal qualitative description. Partners were excluded from the study. RESULTS: Fifty-one participants consented and 39 completed the survey. Mean age was 31 years, 60% had some college level or post-graduate education, 48% had Medicaid insurance, and 81% were Caucasian. More than three-quarters of participants, stated they had either "quite a bit" or "very much" understanding of their fetus's diagnosis. Maternal assessment matched the physician's assessment of accuracy with 77% (N = 30) demonstrating either "quite a bit" or a "very accurate" description of the diagnosis. All women correctly understood if their fetus would require heart surgery. Highest level of maternal education positively correlated with the accuracy of diagnosis (regression coefficient 0.48, p < .002). However, confidence in the diagnosis was independent of both education (0.30, p = .167) and maternal age (-0.03, p = .234). CONCLUSIONS: Fetal counseling is effective in conveying anatomy and the need for surgery; however, accuracy amongst women with lower levels of education and maternal confidence in understanding can be improved.

BACKGROUND: Children with CHD are at risk for obesity and low levels of activity. These factors are associated with an increased risk of poor outcome. Participation in organised sports is an important avenue for children to maintain physical activity, though the relationship between sports participation and obesity has not been examined in the Fontan population. METHODS: We performed a cross-sectional study of children aged 8-18 who had been evaluated between January 1, 2015 and October 1, 2019 at the Doernbecher Children's Hospital outpatient paediatric cardiology clinic and had previously undergone a Fontan. Patients were excluded if they were unable to ambulate independently or if they had undergone a heart transplant. Patient characteristics were recorded from the electronic medical record. Parents were interviewed via a telephone survey and asked to describe their child's activity levels and sports participation. RESULTS: Our final cohort included 40 individuals, 74% were male. The overall prevalence of obesity (CDC BMI >95% for sex/age) in the cohort (23%) was significantly higher in non-athletes (33%) than athletes (0) (p = 0.02). There was no difference in cardiac complications or comorbidities between athletes and non-athletes. Athletes were more likely to meet daily activity recommendations (p = 0.05). CONCLUSION: Fontan patients who do not participate in sports are significantly more likely to be obese and less likely to be active than those who do. This is the first study to demonstrate the association between competitive sports participation and decreased likelihood of obesity in the Fontan population.

Investigations into cooperative partner choice should consider both potential and realised partners, allowing for the comparison of traits across all those available. Male bottlenose dolphins form persisting multi-level alliances. Second-order alliances of 4-14 males are the core social unit, within which 2-3 males form first-order alliances to sequester females during consortships. We compared social bond strength, relatedness and age similarity of potential and realised partners of individual males in two age periods: (i) adolescence, when second-order alliances are formed from all available associates, and (ii) adulthood, when first-order allies are selected from within second-order alliances. Social bond strength during adolescence predicted second-order alliance membership in adulthood. Moreover, males preferred same-aged or older males as second-order allies. Within second-order alliances, non-mating season social bond strength predicted first-order partner preferences during mating season consortships. Relatedness did not influence partner choice on either alliance level. There is thus a striking resemblance between male dolphins, chimpanzees and humans, where closely bonded non-relatives engage in higher-level, polyadic cooperative acts. To that end, our study extends the scope of taxa in which social bonds rather than kinship explain cooperation, providing the first evidence that such traits might have evolved independently in marine and terrestrial realms.

BACKGROUND: Poor menstrual health literacy impacts adolescents' quality of life and health outcomes across the world. The aim of this systematic review was to identify concerns about menstrual health literacy in low/middle-income countries (LMICs) and high-income countries (HICs). METHODS: Relevant social science and medical databases were searched for peer-reviewed papers published from January 2008 to January 2020, leading to the identification of 61 relevant studies. RESULTS: A thematic analysis of the data revealed that LMICs report detrimental impacts on adolescents in relation to menstrual hygiene and cultural issues, while in HICs, issues related to pain management and long-term health outcomes were reported more frequently. CONCLUSIONS: In order to improve overall menstrual health literacy in LMICs and HICs, appropriate policies need to be developed, drawing on input from multiple stakeholders to ensure evidence-based and cost-effective practical interventions.

Facial expressions are complex and subtle signals, central for communication and emotion in social mammals. Traditionally, facial expressions have been classified as a whole, disregarding small but relevant differences in displays. Even with the same morphological configuration different information can be conveyed depending on the species. Due to a hardwired processing of faces in the human brain, humans are quick to attribute emotion, but have difficulty in registering facial movement units. The well-known human FACS (Facial Action Coding System) is the gold standard for objectively measuring facial expressions, and can be adapted through anatomical investigation and functional homologies for cross-species systematic comparisons. Here we aimed at developing a FACS for Japanese macaques, following established FACS methodology: first, we considered the species' muscular facial plan; second, we ascertained functional homologies with other primate species; and finally, we categorised each independent facial movement into Action Units (AUs). Due to similarities in the rhesus and Japanese macaques' facial musculature, the MaqFACS (previously developed for rhesus macaques) was used as a basis to extend the FACS tool to Japanese macaques, while highlighting the morphological and appearance changes differences between the two species. We documented 19 AUs, 15 Action Descriptors (ADs) and 3 Ear Action Units (EAUs) in Japanese macaques, with all movements of MaqFACS found in Japanese macaques. New movements were also observed, indicating a slightly larger repertoire than in rhesus or Barbary macaques. Our work reported here of the MaqFACS extension for Japanese macaques, when used together with the MaqFACS, comprises a valuable objective tool for the systematic and standardised analysis of facial expressions in Japanese macaques. The MaqFACS extension for Japanese macaques will now allow the investigation of the evolution of communication and emotion in primates, as well as contribute to improving the welfare of individuals, particularly in captivity and laboratory settings.

STUDY OBJECTIVE: To explore key aspects of menstrual health literacy and menstrual management in young women at school or in tertiary education. DESIGN: Cross-sectional online survey. SETTING: Australia-wide. PARTICIPANTS: A total of 4202 adolescent and young women (13-25 years of age; median age 17 years), having reached menarche, living in Australia and currently attending school (n = 2421) or tertiary education (n = 1781). INTERVENTIONS: Online survey hosted by Qualtrics between November 2017 and January 2018. Data were collected on contraceptive use, management strategies, sources of information, and knowledge of menstruation. MAIN OUTCOME MEASURES: Information on prevalence and effectiveness of different management strategies, health-seeking behavior, knowledge about menstruation, and common menstrual disorders such as endometriosis. RESULTS: The majority of young women did not seek medical advice for their menstrual symptoms, but used information from the Internet (50%) and engaged in self-management, most commonly with over-the-counter medications such as paracetamol (51%) or ibuprofen (52%). Oral contraceptive use was relatively common (35%), and mostly for reduction of menstrual pain (58%). Despite having significant dysmenorrhea, approximately one-half of the participants (51%) thought that their period was normal. Women with higher pain scores were more likely to rate their period as "abnormal" (P < .0001) but not more likely to consult a doctor (P = .13). Only 53% of those at school had heard of endometriosis. CONCLUSION: Self-management of menstrual symptoms is common, but a significant minority of women are underdosing or choosing ineffective methods. Most women do not seek medical advice even when symptoms are severe, and cannot identify symptoms suggestive of secondary dysmenorrhea. Improved education on menstruation is vital.

STUDY OBJECTIVE: To explore the prevalence and impact of dysmenorrhea, pelvic pain and menstrual symptoms on young women at school or in tertiary education. DESIGN AND SETTING: Cross-sectional online survey in Australia. PARTICIPANTS: A total of 4202 adolescent and young women (13-25 years of age; median age 17 years), having reached menarche, living in Australia and currently attending school (n = 2421) or tertiary education (n = 1781). INTERVENTIONS: Online survey hosted by Qualtrics between November 2017 to January 2018. Data were collected on sociodemographic data, menstrual cycle characteristics, dysmenorrhea, pelvic pain, and educational and social impact. MAIN OUTCOME MEASURES: Information on menstrual and pelvic pain impact, academic absenteeism and presenteeism, impact on non-academic activities and interactions with teaching staff. RESULTS AND CONCLUSIONS: Dysmenorrhea was reported by 92% of respondents. Dysmenorrhea was moderate (median 6.0 on a 0-10 numeric rating scale) and pain severity stayed relatively constant with age [rs(3804) = 0.012, P = .477]. Noncyclical pelvic pain at least once a month was reported by 55%. Both absenteeism and presenteeism related to menstruation were common. Just under half of women reported missing at least one class/lecture in the previous three menstrual cycles. The majority of young women at school (77%) and in tertiary education (70%) reported problems with classroom concentration during menstruation. Higher menstrual pain scores were strongly correlated with increased absenteeism and reduced classroom performance at both school and in tertiary education. Despite the negative impact on academic performance the majority of young women at school (60%) or tertiary education (83%) would not speak to teaching staff about menstruation.

Our study was to apply the 2015 American Heart Association/American College of Cardiology Athletic Participation Guidelines to a group of otherwise healthy school age children and young adults with bicuspid aortic valve (BAV) and describe the potential competitive sports restriction as they age. We performed a retrospective chart review of children and young adults aged 5 to 22 years with isolated BAV with at least two echocardiograms between 2000 and 2013. Using task force guidelines, exercise restriction was recommended for any of the following: (1) any dilation of the aortic root, (2) any dilation of the ascending aorta, (3) moderate aortic stenosis, (4) severe aortic regurgitation; (5) left ventricular dilation or (6) reduced shortening fraction. Of the 345 patients with isolated BAV, 202 were considered restricted at study entry. The final cohort included 123 children and young adults. Over the course of follow up, 36% (44 of 123) met restriction criteria. The most likely cause for restriction was aortic dilation (34%). Progression of aortic valve disease occurred in a minority of patients (3%). There were no reports of death, dissection or catheter or surgical based intervention. In conclusion, we found that strict adherence to current guidelines would result in restriction of more than 1/3 of school age children and young adults with BAV from some form of competitive athletics during school age years. Strict application of the current guidelines in this age group may lead to over-restriction of youths from competitive sports.

Despite the predicted need for a more mathematically capable workforce, the proportion of students undertaking advanced mathematics courses in Australia and other comparable countries has stagnated or fallen, in part due to a lack of student engagement with mathematics in school. In society in general, technology use is commonplace, leading some educators to speculate that technology use for the teaching and learning of mathematics can improve student engagement. In this paper, using multiple case studies, we examine how teachers (n = 10), recognised by their peers as exemplary users of technology, take advantage of technological affordances to optimise student engagement with mathematics. Data was collected from three participant groups: Teachers, Leaders (n = 10), and student focus groups (n = 6). We examine both student and teacher perspectives, through the lens of the Framework for Engagement with Mathematics (FEM), to tease out the ways in which exemplary teachers use technology to enhance pedagogical relationships with students and their pedagogical repertoires. We find that the teachers and students reported evidence of all elements of the FEM, but to differing degrees. In particular, we identified that teachers used technological tools to enhance teacher awareness of individual student learning needs and to promote student-centred pedagogies leading to greater student engagement with mathematics. We contend that a greater awareness of the nuanced pedagogical affordances of a range of technological tools could lead teachers toward practices that enhance student engagement with mathematics, leading to an increase in students wishing to extend their mathematical knowledge beyond the compulsory school years.
RESUMO
INTRODUCTION: This study examined the relationship between personality traits and interpersonal communication skills among first-year orthopedic surgery residents. METHOD: This study performed a retrospective analysis on the data collected in the 2 phases among the 6 cohorts of first-year orthopedic surgery residents (nâ¯=â¯73) during a 6-year period at an urban academic medical hospital. Resident personality was assessed through self-report prior to entry into the program and included a total of 7 personality traits. These traits were broken down into 2 categories, day to day, or usual, tendencies, which measured personality traits when no stress was present and stress tendencies, which measured personality traits when stressed or fatigued. The "day to day" tendencies measured were Emotional Stability, Agreeableness, Conscientiousness and Openness) and "stress" tendencies measured were Excitable, Skeptical and Imaginative. Communication skills were measured across 4 specific dimensions of patient communication (Engage, Empathy, Educate, Enlist) in an Objective Structured Clinical Examination (OSCE). RESULTS: Multiple regression analyses showed that the personality traits identified as "stress" tendencies predicted performance on 2 of the 4 communication skills dimensions measured by the OSCE and accounted for up to 34.8% of the total variance in the ratings of empathic communication and up to 67.2% of the total variance in education-related communication. CONCLUSIONS: Our research identifies specific personality traits that affect resident communication skills related to patient education and empathy in simulated encounters. Three stress-related personality traits (Excitable, Skeptical, Imaginative) had a strong negative influence on communication skills, while day to day personality traits (Emotional Stability, Agreeableness, Conscientiousness) positively influenced communication skills.
