Role of gender and age in influencing dentist perceptions of effective leadership capabilities.

STATEMENT OF THE PROBLEM: The characteristics of effective leaders in dentistry are unknown, especially as they relate to the perceptions of attributes associated with emotional intelligence. PURPOSE: The purpose of this study was to survey dentists about their perceptions of the relative importance of emotional intelligence domains in effective leadership and in effective leaders with whom they have worked and to determine whether the differences were based on gender and age. MATERIAL AND METHODS: A survey was sent to a list of over 50 000 dentists. The survey asked respondents to rate important qualities found in effective leaders in general and to identify important qualities found in the most effective leaders with whom they had worked or by whom they had been mentored. Additionally, demographic information such as the age and gender of the participants was captured in the survey. Descriptive statistics were created and statistical differences (α=.05) between genders were determined. RESULTS: A total of 256 respondents completed the survey. Self-management and relationship management were perceived to be more important than social awareness or self-awareness. Adaptability was the highest ranked personal competence skill, while conflict management was perceived as the least important personal competence skill. The social competence skills of empathy, organizational awareness, influence, and inspirational leadership were similarly ranked as highly important. When asked to identify the most important leadership skill of previous leaders, respondents noted that conflict management was most important and emotional self-awareness was least important. Women viewed the attributes of adaptability, organizational awareness, and conflict management as more important. Men viewed achievement orientation and coaching or mentoring as more important attributes of leaders. When answers were stratified for age group responses, younger respondents valued relationship management and adaptability, and whether their leader valued and exhibited conflict management more than older respondents. Older respondents were more likely to respond "yes" to valuing self-management and to whether their leader valued and exhibited inspirational leadership. CONCLUSIONS: Different genders and different age groups view leadership skills in effective leaders differently. The results of this study indicate that women may need different leadership skills to lead colleagues of different ages.

Antibiograms of field and hospital acquired equine neonatal bacterial fluid cultures in the Midwestern United States: 149 samples (2007-2018).

BACKGROUND: Contemporary data reflecting local pathogens and their antibiograms is necessary to select empirical antimicrobial therapy for equine neonates. HYPOTHESIS/OBJECTIVES: Describe bacterial isolates associated with equine neonatal infection and their antibiograms in the Midwestern United States. An increase in gram-positive infection and antibiotic resistance compared to previous literature was expected. ANIMALS: Data from 149 fluid samples from 133 foals <30 days of age submitted for bacterial culture between January 2007 and December 2018. METHODS: A retrospective evaluation of equine neonatal fluid cultures was performed. Fluid submission type, bacterial culture and antibiogram, empirical antibiotic treatment, and foal outcome was included. Isolate susceptibility to individual antimicrobials and combination protocols relevant to equine practice were recorded. The effect of recorded variables on foal survival was evaluated using Fisher's exact or chi-squared tests. RESULTS: Ninety bacterial isolates (78 aerobes and 12 anaerobes) were identified and gram-positive organisms predominated (n = 50/90, 56%). Greater than 70% of aerobic isolates were susceptible to ampicillin, ceftiofur, chloramphenicol, trimethoprim/sulfamethoxazole, and all penicillin/aminopenicillin and aminoglycoside combinations. Seventy-seven (n = 81/105) percent of foals survived. Survival was associated with a negative fluid culture and was not associated with empirical antimicrobial choice. CONCLUSIONS AND CLINICAL IMPORTANCE: Gram positive and anaerobic isolates associated with equine neonatal fluid cultures exceed that of previous reports. Historical empirical antimicrobial choices for equine neonatal infection in the Midwestern United States are supported by local antibiogram results.

Planet Patrolling: A citizen science brand audit of anthropogenic litter in the context of national legislation and international policy.

Anthropogenic Litter (AL) is ubiquitous in distribution and diverse in type and impact. Citizen science AL clean-ups engage citizens with the environment and have the potential to generate data that can inform policy. Here we present a detailed citizen science survey of AL across freshwater, terrestrial, and coastal environments of the United Kingdom (UK), coordinated by the not-for-profit Planet Patrol throughout 2020. Key materials, industries, brands, and parent companies associated with AL are identified. Plastic dominated AL (63%), followed by metal (14%), and composite materials (12%). The majority of AL (56%) had been used as beverage containers and non-beverage packaging, and 38.8% of AL was branded. Of the branded AL, 26% was associated with The Coca-Cola Company, Anheuser-Busch InBev, and PepsiCo. These three companies were associated with significantly more branded litter than any other. We place these data in the context of upcoming UK legislation and the Environmental Social Governance (ESG) statements of the companies associated with the majority of the recorded litter. Knowledge gaps and recommendations for AL surveying are made, and the focus of corporate and government actions are discussed.

Teenagers and Young Adults with Cancer: An Exploration of Factors Contributing to Treatment Adherence.

This systematic appraisal explores the literature surrounding treatment adherence in teenagers and young adults (TYAs) with cancer, with the aim of identifying influential factors that could affect adherence rates. This area is particularly important due to the increased risk of relapse and death associated with nonadherent behavior. In addition, TYAs are found to be the age group least likely to adhere to medical regimes. A comprehensive review of the literature was conducted and seven studies met the inclusion criteria, the articles were then critiqued using a data extraction form and eight themes were generated and discussed. This review highlights the complexities and difficulties in measuring adherence, as well as the key factors affecting adherence, before identifying implications for practice. Good communication and relationships are crucial between all parties involved in TYAs' care including the patients, professionals, parents, and peers. A model of adherence was adapted on the basis of the result of the systematic review, other literature pertaining to adherence in TYAs, and the clinical experience of the authors. Personal factors and external factors, along with treatment factors and interactions with the system all have an effect on the patient's response or ability to adhere. It is apparent that there is a need for more high-quality qualitative and quantitative research in this area, with an emphasis on finding interventions that directly improve adherence specific to this age group.

Evaluation of the Structure of Myodural Bridges in an Equine Model of Ehlers-Danlos Syndromes.

Myodural bridges have been described in various species as connective tissue structures "bridging" small cranio-cervical muscles to the dura. Myodural bridges are thought to stabilize the dural sac during head and neck movements and promote cerebrospinal fluid motion; however, their role in neurological diseases has not yet been established. We report ultrasonographic visualization, necropsy, histopathologic and ultrastructural findings of myodural bridges in horses with hereditary equine regional dermal asthenia (HERDA), an equine model of Ehlers-Danlos syndromes. Five HERDA and 5 control horses were studied. Post-mortem examination and ultrasonographic studies (3 HERDA and 4 controls) demonstrated that the atlanto-occipital and atlanto-axial myodural bridges are dynamic structures "moving" the dura. En block resection of the myodural bridges (4 HERDA and 5 controls) was accomplished and histopathology showed myofiber degeneration in 3 HERDA horses and 1 control. Ultrastructural examination revealed loosely packed collagen fibrils with abnormal orientation in all HERDA horses compared to mild abnormalities in 2 controls. Our study provides necropsy and ultrasonographic evidence of the dynamic aspect of the myodural bridges as dural sac stabilizers. Myodural bridges may be pathologically altered in connective tissue disease as evidenced by the ultrastructural morphology in the HERDA myodural bridge.

Qualitative research: An overview of emerging approaches for data collection.

OBJECTIVE: The aim of this study was to introduce new approaches to conduct qualitative research that may provide valuable insight into issues related to education, training and patient care in psychiatry. CONCLUSIONS: A variety of data-collection tools is available for researchers and practitioners in psychiatry. These can be used independently or in conjunction with other quantitative and qualitative methods.

Teaching and Learning in an Active Learning Classroom: A Mixed-Methods Empirical Cohort Study of Dental Hygiene Students.

The aim of this study was to discover how an active learning classroom (ALC) influenced the teaching and learning of dental radiology with dental hygiene students through a mixed-methods approach. A year-long observation of a dental hygiene professor who was teaching two consecutive courses in an ALC was conducted in 2015-16. Nineteen classes were recorded and transcribed, and observational notes on classroom activities were taken. Towards the end of the academic year, the professor was interviewed with use of a 13-question guide, and the students were surveyed with a 25-question survey. Moreover, five-year grades in the same two courses, including four-year historical grades earned in the traditional classrooms (TCs) and one year from the ALC, were collected along with demographic and prior academic performance data. Thirty-two of the 38 students responded to the survey, for a response rate of 84%. The results showed that 63% of the students preferred to take classes in the ALC rather than TC. They especially enjoyed the ALC's spaciousness, mobility, unobstructed views, and ease of information-sharing and engagement in class. However, the ALC presented both the faculty and students with sensory and technique challenges. The analysis of students' grades suggested that GPA was one of the strongest predictors for both courses' final grades in the TCs but had weaker predicting significance in the ALC setting. Overall, the majority of students enjoyed taking classes in the ALC due to its physical charm and dynamic collaboration. Sensory and technique challenges coexisted with benefits.

Correction to: Assessing size of pituitary adenomas: a comparison of qualitative and quantitative methods on MR.

We have incorrectly described the ellipsoid equation as being calculated using maximal diameters. It is in fact calculated using half the maximal diameter, i.e. the maximal radii. The diameter is initially recorded on the MRI images (as per Fig. 1), as the lesions do not have a defined midpoint.

Enteral/Parenteral Nutrition in Foals and Adult Horses Practical Guidelines for the Practitioner.

Nutritional support is an important adjunct to medical therapy in the sick, injured, or debilitated equine patient. What is not clear is the optimal route, composition, or amounts of support. The enteral route should be chosen whenever possible to maximize the benefits to the gastrointestinal tract and the patient as a whole. Complete or partial parenteral nutrition is most useful as a bridge during recovery and transition to enteral feeding in the horse. The reader is encouraged to consider nutritional support whether enteral or parenteral in any anorexic, chronically debilitated, or sick equine patient.

Assessing size of pituitary adenomas: a comparison of qualitative and quantitative methods on MR.

BACKGROUND: A variety of methods are used for estimating pituitary tumour size in clinical practice and in research. Quantitative methods, such as maximum tumour dimension, and qualitative methods, such as Hardy and Knosp grades, are well established but do not give an accurate assessment of the tumour volume. We therefore sought to compare existing measures of pituitary tumours with more quantitative methods of tumour volume estimation. METHOD: Magnetic resonance imaging was reviewed for 99 consecutive patients with pituitary adenomas awaiting surgery between 2010 and 2013. Maximal tumour diameter, Hardy and Knosp grades were compared with tumour volume estimates by the ellipsoid equation, [4/3π (a,b,c)], (i.e. ellipsoid volume) and slice-by-slice perimetry (i.e. perimeter volume). RESULTS: Ellipsoid and perimeter methods of tumour volume estimation strongly correlated (R(2) = 0.99, p < 0.0001). However the correlation was less strong with increasing tumour size, with the ellipsoid method slightly underestimating. The mean differences were -0.11 (95 % CI, -0.35, 0.14), -0.74 (95 % CI, -2.2, 0.74) and -1.4 (95 % CI, -6.4, 3.7) for micro-tumours, macro-tumours and giant tumours respectively. Tumour volume correlated with maximal diameter, following a cubic distribution. Correlations of tumour volume with Hardy and Knosp grades was less strong. CONCLUSIONS: Perimeter and ellipsoid methods give a good estimation of tumour volume, whereas Knosp and Hardy grades may offer other clinically relevant information, such as cavernous sinus invasion or chiasmal compression. Thus the different methods of estimating tumour size are likely to have different clinical utilities.

Common Arterial Trunk in a 3-Day-Old Alpaca Cria.

A 3-day-old alpaca cria presented for progressive weakness and dyspnea since birth. Complete bloodwork, thoracic radiographs, and endoscopic examination of the nasal passages and distal trachea revealed no significant findings. Echocardiogram and contrast study revealed a single artery overriding a large ventricular septal defect (VSD). A small atrial septal defect or patent foramen ovale was also noted. Color flow Doppler and an agitated saline contrast study revealed bidirectional but primarily right to left flow through the VSD and bidirectional shunting through the atrial defect. Differential diagnosis based on echocardiographic findings included common arterial trunk, Tetralogy of Fallot, and pulmonary atresia with a VSD. Postmortem examination revealed a large common arterial trunk with a quadricuspid valve overriding a VSD. Additionally, defect in the atrial septum was determined to be a patent foramen ovale. A single pulmonary trunk arose from the common arterial trunk and bifurcated to the left and right pulmonary artery, consistent with a Collet and Edwards' type I common arterial trunk with aortic predominance. Although uncommon, congenital cardiac defects should be considered in animals presenting with clinical signs of hypoxemia, dyspnea, or failure to thrive.

Field triage of the neonatal foal.

The purpose of this article is to provide a quick reference for field triage of the sick neonatal foal. Therefore, information is focused toward diagnostics and treatments that can be performed in the field. When evaluating a weak, recumbent, or lethargic foal on a farm, it is often difficult to make a definitive diagnosis. Therefore, the approach should be to treat what is treatable and prevent what is preventable. In many cases, the goal will be to stabilize a foal before referral to a tertiary care facility where more intensive and continuous treatment can be performed.

Genetics of age-related macular degeneration: current concepts, future directions.

Age-related macular degeneration (AMD) is a progressive degenerative disease which leads to blindness, affecting the quality of life of millions of Americans. More than 1.75 million individuals in the United States are affected by the advanced form of AMD. The etiological pathway of AMD is not yet fully understood, but there is a clear genetic influence on disease risk. To date, the 1q32 (CFH) and 10q26 (PLEKHA1/ARMS2/HTRA1) loci are the most strongly associated with disease; however, the variation in these genomic regions alone is unable to predict disease development with high accuracy. Therefore, current genetic studies are aimed at identifying new genes associated with AMD and their modifiers, with the goal of discovering diagnostic or prognostic biomarkers. Moreover, these studies provide the foundation for further investigation into the pathophysiology of AMD by utilizing a systems-biology-based approach to elucidate underlying mechanistic pathways.

Comparison of temporal artery to rectal temperature measurements in children up to 24 months.

This descriptive study compared temporal artery (TA) and rectal temperature measurements, patient comfort during temperature measurements, and nursing time required to obtain temperature measurements. Study participants (n = 40) included children 0-24 months old with fever higher than 38°C, admitted to a freestanding children's hospital in the Midwest. Statistical analysis of 450 paired TA and rectal temperature measurements revealed a 0.776 correlation, mean difference of 0.03°C, and 94.7% of measurements differing by less than 1.0°C. Patient comfort, measured via the Face, Legs, Activity, Cry, Consolability Scale, was enhanced with TA thermometry compared to rectal. TA thermometry resulted in an 87% savings of nursing time.

The dental hygiene faculty shortage: causes, solutions and recruitment tactics.

PURPOSE: Peer-reviewed professional publications were examined for pertinent information associated with faculty shortages in the dental professions. The review found 6 suggested causes, including inadequate compensation, lack of diversity amongst faculty, inadequate mentoring for new faculty, lack of modeling to prospective dental hygiene educators, little awareness of faculty shortages and lack of institutional support for dental hygiene faculty. The causes and solutions for faculty shortages and recruitment tactics employed by parallel professions were evaluated to determine their applicability to the dental hygiene faculty shortage. There remains a scarcity of information regarding dental hygiene faculty shortages and how dental hygiene programs and institutions should address such shortages.

Nutrition of critically ill horses.

Nutritional supplementation is becoming the standard of practice in equine medicine, although there are minimal data on nutritional support in critically ill horses and its association or effect on morbidity and mortality or length of hospital stay. Horses can be fed orally and when that is not possible, intravenously or parenterally. Enteral feeding is less expensive, more physiologic, improves immunity, and is easier and safer. This article reviews available information on the development of a nutritional plan for critically ill horses, and describes methods for and complications of enteral and parenteral feeding.
