RESUMO
It is important to recognize and celebrate the contributions of psychologists at Academic Health Centers (AHCs). Recognition events can help attract, retain, and honor professionals who play essential roles in healthcare. This case study describes the establishment of a national Psychology Recognition Week in the Department of Veterans Affairs and offers a model for other AHCs looking to implement a similar initiative. This case study outlines several factors that contributed to the success of developing a recognition week, including the involvement of leadership at all levels, forming a planning committee, setting milestones, building infrastructure, and fostering partnerships.
RESUMO
BACKGROUND: Humeral nonunion is estimated to occur at a rate of 1.1%-25% depending on the fracture location and pattern, mechanism of injury, patient compliance with the immobilization protocol and patient's nutritional status and medical comorbidities. Fracture nonunion can cause chronic pain and limited range of motion and may hinder normal function. There is very little data from the patients' perspective regarding their experience with a humeral nonunion. The aim of this study was to establish health-related quality of life (HRQoL) norms for patients diagnosed with a humeral nonunion. MATERIALS AND METHODS: We reviewed a prospectively collected database of 185 humeral nonunions seen and treated at our quaternary referral center. We recorded patient characteristics including sex, age, history of infection, previous surgery, associated nerve palsy, handedness, and the anatomic location of the nonunion. At initial clinical evaluation, all patients were asked to complete the 12-Item Short Form Health Survey (SF-12), Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, Brief Pain Inventory (BPI), and a time trade-off questionnaire. These scores were compared to other well-known chronic medical conditions' HRQoL scores. RESULTS: The cohort reported an average utility score of 0.55 ± 0.35, average SF-12 Physical Component Summary score of 30.2 ± 7.6, average SF-12 Mental Component Summary score of 42.5 ± 6.1, and average raw DASH score of 69 ± 21, which was worse than the general US population, patients with asthma, hypertension, stroke, type 2 diabetes, and AIDS. Patients with humeral nonunion are willing to trade 45% of their remaining life to obtain perfect health, and when stratified by handedness, we found that patients with a humeral nonunion of their dominant arm were willing to trade 49.7% compared with 39.7% in patients with a humeral nonunion of their nondominant arm (P = .04). DISCUSSION: The results of our study show that humeral nonunion is a chronic medical condition that has a debilitating effect on patients, both physically and mentally. It is important for orthopedic surgeons to acknowledge these conditions as physically and mentally debilitating to their patients. Our study highlights these physical and mental burdens and helps to quantify humeral nonunion in relation to more well-known chronic conditions, such as asthma, diabetes, AIDS, and stroke. CONCLUSIONS: Humeral nonunions have a devastating effect on a patient's physical and mental health with HRQoL measures lower than patients with other chronic conditions, such as asthma, diabetes, AIDS, and stroke. We found that our patients, on average, would trade approximately 45% of their remaining life span for perfect health.

In the present study, we examined administrative data on 667,437 deployments of at least 30 days duration to Iraq and Afghanistan from 2011 through the end of 2016 to determine risk factors for evacuation from the combat zone for behavioral health reasons. Demographic data, military-specific data, responses on predeployment mental health assessments, and presence of previous treatment for psychiatric conditions were entered into a logistic regression based on expert determination, distinguishing the 2,133 behavioral health evacuations from those deployments that either did not end in evacuation or included evacuations for reasons other than behavioral health. The model, derived from a random half of the sample (training set), was verified on the other half (validation set). Predictor variables used in the model were calendar year; gender; age; rank; marital status; parental status; number of prior war zone deployments; branch of service; screens for symptoms of posttraumatic stress disorder, depression, and hazardous alcohol use on the predeployment mental health assessment; and prior substance- and non-substance-related behavioral health diagnoses. Odds ratios (range: 1.05-3.85) for selected variables that contributed to the model were used to assign risk scores in the Behavioral Health Evacuation Risk Tool, which can aid predicting which service members are more likely to be evacuated from combat for behavioral health reasons, thus indicating where resources can be allocated for behavioral health referrals and war zone care.

Studies in adult HT have demonstrated improved cardiac function in the recipient following administration of T3 to the donor. The purpose of this experiment was to assess the effects of T3 on the function of the immature donor heart following HT in a piglet model. A total of 32 piglets were divided into 16 donors and 16 recipients. Following creation of brain death, half of the donor piglets were randomized to receive three doses of T3 (0.2 µg/kg) along with hydrocortisone (1 mg/kg). The donor hearts were then transplanted into the recipient piglets on CPB. Duration of survival off CPB, inotrope score, and EF of heart following CPB were evaluated. There were no differences between the two groups in age, weight, pre-brain death EF, T3 levels, and CPB times. Post-CPB survival times were inversely related to the ischemic times in both groups (Pearson r=-0.80, P<.001), and this relationship was not influenced by T3. There was no difference in inotrope score, EF, or biochemical assessment between the two groups. Administration of T3 in combination with hydrocortisone to the brain-dead donor confers no beneficial effect on myocardial function or survival following HT in a piglet model.

BACKGROUND: Although morbidity and mortality in children increases in motor vehicle collisions (MVC) if child restraints are not used, no data exist correlating specific injuries with proper or improper use of safety restraints or age. The purpose of this study was to evaluate correlations between childhood MVC injuries, age, and restraint status. METHODS: A medical record search for pediatric patients involved in a MVC was conducted at a pediatric hospital (level 1 trauma). Charts were reviewed for demographics and injury-specific information. Patients were grouped by age, restraint use, and injuries. RESULTS: Nine hundred sixty-seven patients ≤12 years (average age 6.39 y) were identified. Being properly restrained was most common in all age groups except the 4- to 8-year age group in which being improperly restrained was most common. Unrestrained patients were most commonly found in the 9- to 12-year age group. A statistically significant difference was not observed for orthopaedic injuries among the restraint groups, but internal thoracic injuries, open head wound, and open upper extremity wounds were significantly more common in improperly or unrestrained patients. Improperly restrained infants had a significantly higher rate of intracranial bleeds and abrasions than those properly restrained. Unrestrained and improperly restrained 9- to 12-year olds had significantly more open head, open upper extremity, and vascular injuries. When comparing injury types with age groups, upper extremity fractures, femoral fractures, dislocations, and spinal fractures were found to be significantly higher in older children. CONCLUSIONS: Preventing orthopaedic injuries in older children may be accomplished by changes in regulations or automotive safety equipment. Rear-facing child safety seats could possibly be improved to prevent head trauma in the youngest patients. There is a continued need to reinforce the importance of proper use of child safety devices to parents. Knowledge of the patient's age, along with restraint status, might aid in diagnosis of less obvious MCV injuries. LEVEL OF EVIDENCE: Level III.

Massive rotator cuff tears are a common issue for patients and can be challenging to manage surgically. While the literature has shown that repair construct can affect the outcome of a rotator cuff repair, and the double-row repair is typically favored over the single-row repair for larger rotator cuff tears, the double-row repair also has some shortcomings. These shortcomings are related to the increased technical difficulty of the procedure, as well as increased costs due to the increased number of anchors used. Both of these factors also lead to an increase in the amount of time spent in the operating room as well. This study describes a surgical technique to help mitigate this shortcoming of the double-row repair by using a single medial-row anchor in our double-row construct for repair of a massive rotator cuff tear.
RESUMO
BACKGROUND: This study establishes measurements to evaluate pathologic compensation in rotator cuff tear arthropathy and resultant considerations for reverse shoulder arthroplasty. METHODS: Radiographs of patients with intact rotator cuffs were measured establishing interobserver and intraobserver reliability. Reverse shoulder arthroplasty cases performed by a single surgeon were then retrospectively reviewed. One year of follow-up radiographs were required for inclusion. Preoperative radiographs were analyzed for relative humeral head elevation ratio and humeral abduction relative to the glenoid face, termed the glenoid-intramedullary humeral angle. Statistical analyses assessed associations for radiographic measurements with presence and severity of scapular notching based on the Nerot-Sirveaux classification system. RESULTS: A total of 221 patients met inclusion criteria. At the 1-year follow-up, 61 (27.6%) shoulders had radiographic notching. There was a moderately strong (r = -0.56) negative correlation between glenoid-intramedullary humeral angle and humeral head elevation ratio. Patients with humeral head elevation ratio ≥ 20% were significantly (P = .024) and 9.2 times more likely to have notching of any grade. Patients with glenoid-intramedullary humeral angle ≤ 5 degrees were significant (P < .0001) and 6.7 times more likely to have notching of any grade and significantly (P = .00018) and 145 times more likely to have high-grade (3 and 4) notching. CONCLUSIONS: Preoperative humeral head elevation and compensatory scapular rotation with relative adduction of the humerus have significant associations with high-grade notching. These radiographic findings have potential to help surgeons in preoperative decision-making regarding implant choice and patient education.
RESUMO
BACKGROUND: Surgical treatment of posterolateral rotatory instability (PLRI) using primary repair or reconstruction of the lateral collateral ligament complex have proven inconsistent. This study aimed to test the hypothesis that augmentation of LUCL repair or palmaris longus tendon reconstruction using a suture tape augmentation would be associated with less rotational displacement and greater torque load to failure (LTF) compared with nonaugmented constructs. METHODS: Cadaveric elbows (n = 12 matched pairs) were used. Baseline stiffness and displacement values were obtained. The LUCL was transected followed by repair alone, repair with augmentation, reconstruction with palmaris longus graft, or reconstruction with augmentation. Specimens were retested including torque LTF. Paired t tests were performed to assess the biomechanical effects of augmentation. RESULTS: Augmentation was associated with higher LTF than repair and reconstruction alone (P = .008 and .047, respectively). Displacement was less with augmentation in reconstruction groups (P = .048) but not in repair groups. Suture tape augmentation maintained rotational stiffness better than repair alone (P = .01). Although reconstruction with augmentation maintained rotational stiffness better than nonaugmented reconstruction, the differences were not statistically significant (P = .057). Mode of failure for repair alone was predominantly suture pulling through repaired ligament. Augmented repairs primarily failed at the anchor-bone interface. Modes of failure for both reconstruction groups were similar, including graft tearing and/or slipping at the anchor. CONCLUSION: When positioned in neutral forearm rotation and 90o of flexion to simulate postoperative conditions, augmentation of LUCL repair or tendon reconstruction using suture tape is associated with better resistance to rotational loads compared with nonaugmented repair or reconstruction, while maintaining near-native rotational stiffness.
RESUMO
BACKGROUND: Anterior vertebral body tethering (VBT) is an early treatment option for progressive scoliosis in pediatric patients, allowing for continued deformity correction during normal growth. We report postoperative radiographic and clinical outcomes for patients treated with VBT. METHODS: This clinical and radiographic retrospective review of 31 consecutive patients included an analysis of preoperative, perioperative, and postoperative details, including the Lenke classification; Cobb angle measurements of the proximal thoracic, main thoracic, and lumbar curves; the sagittal profile; and skeletal maturity. Successful outcomes were defined by a residual curve of ≤30° in skeletally mature patients who did not undergo a posterior spinal fusion (PSF). RESULTS: Of the 31 patients treated, 29 met the inclusion criteria, and 2 were lost to follow-up. The mean patient age (and standard deviation) at the time of the surgical procedure was 12.7 ± 1.5 years (range, 10.2 to 16.7 years), with most patients classified as Risser grade 0 or 1 (52%) and Sanders stage 3 (32%). A mean of 7.2 ± 1.4 vertebral levels were instrumented, with a minimum preoperative Cobb angle of 42°. At the latest follow-up, 27 patients had reached skeletal maturity (Sanders stage ≥7) and 20 patients exhibited a curve magnitude ≤30°, for a success rate of 74%. A suspected broken tether occurred at ≥1 level in 14 patients (48%). Two patients underwent PSF and 4 had tether revision. The overall revision rate was 21% (6 of 29). CONCLUSIONS: This study shows the success and revision rates as well as the impact of a suspected broken tether on the procedural success of VBT. Despite our patient population being slightly more mature at the time of the surgical procedure compared with previous studies, we had a higher success rate and a lower revision rate. A PSF was avoided in 93% of patients, indicating that VBT may be a reliable treatment option for adolescent scoliosis in skeletally immature individuals. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

BACKGROUND: The biconcave (B2) glenoid is characterized by preservation of the anterior portion of the native glenoid with asymmetric wear of the posterior glenoid. Surgical options for glenoid correction have evolved. The goal of shoulder arthroplasty is to place the implants in such a manner to return the humeral head to a centered position and restore the joint line to a neutral position. There is no current consensus on method of treatment and correction. METHODS: The current and historical literature on total shoulder arthroplasty was used to examine technique viability. RESULTS: Asymmetric remaining can be used to address up to 15° of version correction without compromise of cortical bone. It is important to have the proper presurgical planning, to understand the limitations of correction, and to have other options available to treat the biconcave glenoid.
RESUMO
BACKGROUND: Prospective orthopedic residency applicants commonly use one of three databases to identify potential programs: Accreditation Council of Graduate Medical Education (ACGME), American Medical Association (FREIDA), or Orthogate. org. In addition, institutional websites are typically the primary source of information once programs are identified. We sought to evaluate the databases and websites used by prospective orthopedic surgery applicants for content and accessibility. We hypothesized that information would be more available in comparison to previous studies but would still fail to provide complete, up to date program information for the prospective applicant. METHODS: Three online databases were queried in December 2014 to compile a list of orthopedic residency programs in the United States. This combined list was used as a basis for evaluating individual institution websites. Previously described criteria were used to evaluate the availability of information contained within orthopedic surgery residency websites. RESULTS: At the time of online review, 157 programs were identified. Depending on the database in question, up to 33% of programs either did not provide a link or listed a non-functioning link. Among the variety of evaluated criteria, inclusion of the information varied between 12% and 97% for the individual program websites. CONCLUSIONS: Online databases are useful in listing programs, but individual program details and direct functional links are lacking. Most program websites contain varying degrees of desired information; however, not all programs maintain websites which consistently provide information to satisfy the evaluated criteria in this study. Improved online accessibility and availability of information for residency programs would increase their visibility and utility for prospective applicants.

OBJECTIVE: Bradford's law describes the scatter of citations for a given subject or field. It can be used to identify the most highly cited journals for a field or subject. The objective of this study was to use currently accepted formulations of Bradford's law to identify core journals of neurosurgery and neurosurgical subspecialties. METHODS: All original research publications from 2009 to 2013 were analyzed for the top 25 North American academic neurosurgeons from each subspecialty. The top 25 were chosen from a ranked career h-index list identified from previous studies. Egghe's formulation and the verbal formulation of Bradford's law were applied to create specific citation density zones and identify the core journals for each subspecialty. The databases were then combined to identify the core journals for all of academic neurosurgery. RESULTS: Using Bradford's verbal law with 4 zone models, the authors were able to identify the core journals of neurosurgery and its subspecialties. The journals found in the most highly cited first zone are presented here as the core journals. For neurosurgery as a whole, the core included the following journals: Journal of Neurosurgery, Neurosurgery, Spine, Stroke, Neurology, American Journal of Neuroradiology, International Journal of Radiation Oncology Biology Physics, and New England Journal of Medicine. The core journals for each subspecialty are presented in the manuscript. CONCLUSIONS: Bradford's law can be used to identify the core journals of neurosurgery and its subspecialties. The core journals vary for each neurosurgical subspecialty, but Journal of Neurosurgery and Neurosurgery are among the core journals for each neurosurgical subspecialty.

Visual systems of open habitat vertebrates are predicted to have a band of acute vision across the retina (visual streak) and wide visual coverage to gather information along the horizon. We tested whether the eastern meadowlark (Sturnella magna) had this visual configuration given that it inhabits open grasslands. Contrary to our expectations, the meadowlark retina has a localized spot of acute vision (fovea) and relatively narrow visual coverage. The fovea projects above rather than towards the horizon with the head at rest, and individuals modify their body posture in tall grass to maintain a similar foveal projection. Meadowlarks have relatively large binocular fields and can see their bill tips, which may help with their probe-foraging technique. Overall, meadowlark vision does not fit the profile of vertebrates living in open habitats. The binocular field may control foraging while the fovea may be used for detecting and tracking aerial stimuli (predators, conspecifics).

To examine patterns of executive dysfunction associated with ADHD, 123 children (54 ADHD, 69 controls) of ages 8-16 years were administered selected subtests from the Delis-Kaplan Executive Function System (D-KEFS). Children with ADHD performed significantly worse than controls on measures of both basic (less executive demand) skills and those with more executive demand from the Color-Word Interference and Tower subtests; however, no group differences were noted on any of the D-KEFS contrast scores. Most subtype comparisons yielded no differences; however, children with the Combined subtype outperformed children with the Inattentive subtype on measures of both basic and executive skills from the Trail Making Test. Children with ADHD demonstrate executive dysfunction that is identified by D-KEFS summary, but not contrast scores. In this carefully screened sample of children with ADHD, few significant differences were found between groups suggesting limited sensitivity or specificity of the D-KEFS for classifying children with ADHD.

To examine effects of group (Attention-Deficit/Hyperactivity Disorder [ADHD] versus Typically Developing [TD]), sex, and ADHD subtype on "process/optional" measures of executive functioning, children (n = 123; 54 ADHD, 69 TD) aged 8-16 completed subtests from the D-KEFS. No group, sex, or ADHD subtype effects were found on optional measures from the Trail Making, Color-Word Interference, and Tower tests. A significant interaction was found for Verbal Fluency Total Repetition Errors; boys with Combined/Hyperactive-Impulsive (ADHD-C/HI) type ADHD performed better than ADHD-C/HI girls, whereas girls with Inattentive type ADHD (ADHD-I) performed better than ADHD-I boys. Overall, children with ADHD did not differ from TD on most optional measures from the D-KEFS. When sex and ADHD subtype were considered, children with the subtype of ADHD less common for sex were at greater risk for poorer performance.

This issue brief examines reported capacity constraints in inpatient psychiatric services and describes how these services fit within the continuum of care for mental health treatment. The paper summarizes the type and range of acute care services used to intervene in mental health crises, including both traditional hospital-based services and alternative crisis interventions, such as mobile response teams. It reviews historical trends in the supply of inpatient psychiatric beds and explores the anticipated influence of prospective payment for inpatient psychiatric services under Medicare. The paper also considers other forces that may affect the need for and supply of acute mental health services, including key factors that could improve the quality and efficiency of inpatient psychiatric care.

The present study compared performance of children with Attention-Deficit/Hyperactivity Disorder (ADHD) and high functioning autism (HFA) with that of controls on 4 tasks assessing 2 components of motor control: motor response inhibition and motor persistence. A total of 136 children (52 ADHD, 24 HFA, 60 controls) ages 7 to 13 years completed 2 measures of motor inhibition (Conflicting Motor Response and Contralateral Motor Response Tasks) and 2 measures of motor persistence (Lateral Gaze Fixation and NEPSY Statue). After controlling for age, IQ, gender, and basic motor speed, children with ADHD performed significantly more poorly than controls on the Conflicting Motor Response and Contralateral Motor Response Tasks, as well as on Statue. In contrast, children with HFA achieved lower scores than controls only on measures of motor persistence, with no concomitant impairment on either motor inhibition task. These results are consistent with prior research that has demonstrated relatively spared motor inhibition in autism. The findings highlight the utility of brief assessments of motor control in delineating the unique neurobehavioral phenotypes of ADHD and HFA.

Lexical decision tasks have been used to study both shifts of attention and semantic processing in Parkinson's Disease (PD). Whereas other laboratories have reported normal levels of semantic priming among PD patients, our laboratory has reported abnormally large levels. In this study, two experiments were performed to determine the influence of task structure on the extent of semantic priming during lexical decision-making and pronunciation tasks among PD patients and neurologically healthy controls. In Experiment 1, the effect of Prime Dominance (the ratio of category to neutral trials) on lexical decision-making was studied. Although equal numbers of word and nonword trials were presented, half of the PD patients and controls were studied under Category Prime Dominance (category : neutral prime ratio of 2:1) and half were studied under Neutral Prime Dominance (category : neutral prime ratio of 1:2). In Experiment 2, PD and control participants were studied on lexical decision-making and pronunciation tasks where twice as many words as nonword trials were presented, consistent with other studies from our laboratory. In Experiment 1, we found no group differences in the magnitude of priming and no effect of Prime Dominance. Moreover, the findings were similar in pattern and magnitude to results published by Neely (1977). In Experiment 2, we observed larger priming effects among PD patients than among controls, but only on the lexical decision (LD) task. These results support the hypothesis that abnormally large category-priming effects appear in LD studies of PD patients when the number of word trials exceeds the number of nonword trials. Furthermore, increased lexical priming in PD appears to be due to processes operating during the decision-making period that follows presentation of the lexical target.

Doctoral students in professional psychology face broad challenges, such as changing market demands and increased competition for careers in traditional practice settings. To prepare for these demands, students must decide how much and when to specialize, if at all, predoctorally. Complicating matters, students in single practice area programs (clinical, counseling, or school) may risk becoming insulated within the culture of their practice area, which can limit exposure and understanding of the larger practice field. Despite conditions that may drive potential students away from psychology, little research exists on efforts to address student needs, or on student perspectives of doctoral training in general. One training model that is sensitive to these student needs and concerns is the Combined-Integrated (C-I) model. An exploratory study of C-I student and graduate opinions, experiences, and aspirations revealed that C-I students value breadth of training, diversity of experience, and professional flexibility, and that they experience diverse training opportunities and socialization experiences. Implications of these results vis-à-vis the larger framework of student concerns are examined.
