The dynamics of dyadic interactions between people of different ethnicities depend on their identification with all humanity.

Individuals who have the disposition to identify with all humanity declare feeling close to people all over the world, caring about them, and perceiving them as an ingroup. However, never before were such declarations verified by measures of intergroup attitudes less direct than questionnaires, such as approach/avoidance tendencies or dynamical systems methods. Since individuals with higher dispositional identification with all humanity (IWAH) perceive people all over the world as ingroup members, we expected differences in the dynamic of inter-ethnic interactions (spatial distance, coordination, coupling, and leading), depending on a participant's level of IWAH.

Late gestation predictors of a postnatal biventricular circulation after fetal aortic valvuloplasty.

Objectives: Fetal aortic valvuloplasty (FAV) for severe aortic stenosis (AS) has shown promise in averting progression to hypoplastic left heart syndrome. After FAV, predicting which fetuses will achieve a biventricular (BiV) circulation after birth remains challenging. Identifying predictors of postnatal circulation on late gestation echocardiography will improve parental counseling.

Ultrasound-Guided Microinvasive Trigger Finger Release Technique Combined With Three Tests to Confirm a Complete Release.

Objective: Trigger finger at the A1 pulley is a common cause of hand pain leading to functional limitations. This study evaluated the outcomes of patients treated with a microinvasive ultrasound-guided trigger finger release technique using an 18 blade and described three tests that confirm a complete release.

Design: A retrospective chart review and cross-sectional study of 46 cases of A1 pulley trigger finger releases in 28 patients performed at a private, sports medicine clinic using this technique were completed, meeting power criteria.

Acute Effects of Weighted Baseball Throwing Programs on Shoulder Range of Motion.

Background: Baseball pitching injuries are increasing at an alarming rate. While weighted ball throwing programs may be effective at increasing pitching velocity, previous research has identified a 24% injury rate and a 3.3° increase in shoulder external rotation (ER) range of motion (ROM) after performing a 6-week program.

Low mortality in fetal supraventricular tachycardia: Outcomes in a 30-year single-institution experience.

Objectives: To describe a single institutional experience managing fetuses with supraventricular tachycardia (SVT) and to identify associations between patient characteristics and fetal and postnatal outcomes.

Background: Sustained fetal SVT is associated with significant morbidity and mortality if untreated, yet the optimal management strategy remains unclear.

Methods: Retrospective cohort study including fetuses diagnosed with sustained SVT (>50% of the diagnostic echocardiogram) between 1985 and 2018.

Clinical Outcomes of Percutaneous Plantar Fasciotomy Using Microdebrider Coblation Wand.

Background: Plantar fasciitis is the most common cause of heel pain in adults. Multiple conservative treatment plans exist; however, some cases do not obtain significant clinical improvement with conservative treatment and require further intervention. This retrospective case study evaluated the success rate of percutaneous plantar fasciotomy and confounding comorbidities that negatively affect outcomes.

Baseball Pitching Biomechanics Shortly After Ulnar Collateral Ligament Repair.

Background: The probability of returning to competition for injured baseball pitchers is similar after ulnar collateral ligament (UCL) repair as after UCL reconstruction, but the time to return is significantly quicker after UCL repair. Previous research has found no differences in pitching biomechanics between pitchers with and without a history of UCL reconstruction, but pitching biomechanics after UCL repair has not been studied.

Hypothesis: There will be significant differences in pitching biomechanics between pitchers returning to play after UCL repair and pitchers with no injury history.

The relationship between variability in baseball pitching kinematics and consistency in pitch location.

The purpose of this study was to explore the relationship between variability in pitching kinematics and consistency in pitch location. Data were collected for 47 healthy baseball pitchers throwing ten full-effort fastballs to the centre of the strike zone. For each pitch, 20 kinematic parameters were calculated with an automated motion capture system while pitch location was measured with a PITCHf/x system.

Ulnar Collateral Ligament Repair With Collagen-Dipped FiberTape Augmentation in Overhead-Throwing Athletes.

Background: There has been a renewed interest in ulnar collateral ligament (UCL) repair in overhead athletes because of a greater understanding of UCL injuries, an improvement in fixation technology, and the extensive rehabilitation time to return to play.

Purpose/hypothesis: To evaluate the clinical outcomes of a novel technique of UCL repair with internal brace augmentation in overhead throwers.

Study Design: Case series; Level of evidence, 4.

The influence of mound height on baseball movement and pitching biomechanics.

Objectives: To determine whether mound height is associated with baseball movement (velocity, spin and break) and baseball pitching biomechanics (kinematics and kinetics).

Design: Controlled laboratory study.

Methods: Twenty collegiate baseball pitchers threw five fastballs and five curveballs from four different mound heights (15cm, 20cm, 25cm, 30cm) in a randomized order.

Echocardiographic predictors of neonatal illness severity in fetuses with critical left heart obstruction with intact or restrictive atrial septum.

Background: Neonates with critical left heart obstruction and intact atrial septum (IAS) or restrictive atrial septum (RAS) are at risk for hypoxia within hours of birth and remain a group at high risk for mortality.

Methods: Prenatally diagnosed fetuses with critical left heart obstruction and IAS or RAS with follow-up from January 1, 2005, to February 14, 2017, were included. Primary outcome was a composite measure of severe neonatal illness (pH < 7.

Early hemodynamic changes after fetal aortic stenosis valvuloplasty predict biventricular circulation at birth.

Objective: To describe the early hemodynamic changes after fetal aortic valvuloplasty (FAV) for evolving hypoplastic left heart syndrome due to mid-gestational aortic stenosis and to assess whether these early changes predict biventricular (BiV) circulation at neonatal discharge.

Method: We retrospectively reviewed all technically successful FAV cases resulting in live birth between 2000 and 2015 (n = 93, 45% BiV circulation at neonatal discharge). Paired testing methods were used to compare pre-intervention and post-intervention measures of left ventricular hemodynamics.

Improved technical success, postnatal outcome and refined predictors of outcome for fetal aortic valvuloplasty.

Objectives: Fetal aortic valvuloplasty (FAV) may prevent progression of mid-gestation aortic stenosis to hypoplastic left heart syndrome (HLHS). The aim of this study was to evaluate whether technical success and biventricular (Biv) outcome after FAV have changed from an earlier (2000-2008) to a more recent (2009-2015) era and identify pre-FAV predictors of Biv outcome.

Methods: We evaluated procedural and postnatal outcomes in 123 fetuses that underwent FAV for evolving HLHS at Boston Children's Hospital between 2000 and 2015.

Cardiac output and blood flow redistribution in fetuses with D-loop transposition of the great arteries and intact ventricular septum: insights into pathophysiology.

Objectives: Although the postnatal physiology of D-loop transposition of the great arteries with intact ventricular septum (D-TGA/IVS) is well established, little is known about fetal D-TGA/IVS. In the normal fetus, the pulmonary valve (PV) is larger than the aortic valve (AoV), there is exclusive right-to-left flow at the foramen ovale (FO) and ductus arteriosus (DA), and the left ventricle (LV) ejects 40% of combined ventricular output (CVO) through the aorta, primarily to the brain. In D-TGA/IVS, the LV ejects oxygen-rich blood to the pulmonary artery, theoretically leading to pulmonary vasodilation, increased branch pulmonary artery flow and reduced DA flow.
