Imaging Modalities for the Glenoid Track in Recurrent Shoulder Instability: A Systematic Review.

Orthop J Sports Med 2021 Jun 3;9(6):23259671211006750. Epub 2021 Jun 3.

Steadman Philippon Research Institute, Vail, Colorado, USA.

Background: The glenoid track (GT) concept illustrates how the degree of glenoid bone loss and humeral bone loss in the glenohumeral joint can guide further treatment in a patient with anterior instability. The importance of determining which lesions are at risk for recurrent instability involves imaging of the glenohumeral joint, but no studies have determined which type of imaging is the most appropriate.

Purpose/hypothesis: The purpose of this study was to determine the validity and accuracy of different imaging modalities for measuring the GT in shoulders with recurrent anterior instability. Read More

Need satisfaction in intergroup contact: A multinational study of pathways toward social change.

J Pers Soc Psychol 2021 Jun 17. Epub 2021 Jun 17.

Department of Psychology, University of Groningen.

What role does intergroup contact play in promoting support for social change toward greater social equality? Drawing on the needs-based model of reconciliation, we theorized that when inequality between groups is perceived as illegitimate, disadvantaged group members will experience a need for empowerment and advantaged group members a need for acceptance. When intergroup contact satisfies each group's needs, it should result in more mutual support for social change. Using four sets of survey data collected through the Zurich Intergroup Project in 23 countries, we tested several preregistered predictions, derived from the above reasoning, across a large variety of operationalizations.

Anger regulation choice-The role of age and habitual reappraisal.

Emotion 2021 Jun 17. Epub 2021 Jun 17.

Department of Neurology, Max Planck Institute for Human Cognitive and Brain Sciences.

The ability to choose emotion regulation strategies in accordance to contextual demands, known as emotion regulation flexibility, is key to healthy adaptation. While recent investigations on spontaneous emotion regulation choice tested the effects of emotional intensity and age using standardized negative pictures with no particular emotional quality, we elicited the discrete emotion of anger with personally relevant autobiographical memories in a sample of 52 younger and 41 older adults. In addition, we included habitual reappraisal as a predictor of emotion regulation choice. Read More

Data Brief 2021 Aug 14;37:107129. Epub 2021 May 14.

Department of Biomedical Engineering, Lerner Research Institute, Cleveland Clinic, Cleveland, OH 44195, USA.

Osteoarthritis (OA) is a leading cause of disability in older adults and takes substantial toll at personal, economic and societal levels. There is inadequate comprehension of OA disease progression specifically during the early phases of OA. This knowledge is critical to understanding the heterogeneity in OA progression as well as enable development of targeted therapeutics at the start of the disease rather than end-stage. Read More

Quality of life, emotion regulation, and dissociation: Evaluating unique relations in an undergraduate sample and probable PTSD subsample.

Psychol Trauma 2021 Jun 10. Epub 2021 Jun 10.

Department of Psychology, Binghamton University (SUNY).

Objective: Previous research has documented a strong association between emotion regulation (ER) and quality of life (QoL). Nevertheless, extant studies have not tested this association in participants meeting diagnostic criteria for posttraumatic stress disorder nor accounted for other explanatory variables statistically. Our primary objective was to evaluate the unique relations among ER dimensions and QoL while controlling for dissociation, neuroticism, and PTSD symptoms statistically. Read More

Spontaneous mental replay of music improves memory for incidentally associated event knowledge.

J Exp Psychol Gen 2021 Jun 10. Epub 2021 Jun 10.

Department of Psychology.

Why is music effective at evoking memories from one's past? Familiar music is a potent cue that can trigger, often involuntarily, the recollection of associated autobiographical memories. The mechanisms by which associations between music and nonmusical knowledge initially form and consolidate into long-term memory have not been elucidated. In three experiments, we linked two common musical phenomena, involuntary musical imagery (INMI; commonly called "earworms") and music-evoked remembering, in testing the hypothesis that such imagery aids in the consolidation of memory for events with which music becomes associated.

Evidence from an fMRI study that dessert-flavored e-cigarettes engage taste-related, but not smoking-related, brain circuitry for female daily smokers.

Exp Clin Psychopharmacol 2021 Jun 10. Epub 2021 Jun 10.

Department of Neurosurgery.

Regulations limiting the sale of flavored e-cigarette products are controversial for their potential to interfere with e-cigarette use as a cessation aid in addition to curbing youth use. Limited research suggests that flavor might enhance the addictive potential of e-cigarettes; however, the acute effects of flavored aerosols on brain function among humans have not been assessed. The present study aimed to isolate and compare the neural substrates of flavored and unflavored e-cigarette aerosols on brain function among nine female daily smokers. Read More

Beyond olfaction: Beneficial effects of olfactory training extend to aging-related cognitive decline.

Behav Neurosci 2021 Jun 10. Epub 2021 Jun 10.

Smell and Taste Clinic.

Studies on olfactory training (OT) outcomes have mostly been limited to olfactory performance, while direct neural connections between olfactory system and amygdala-hippocampal complex allow expecting OT to have psychological effects. To address this hypothesis, we examined olfactory, cognitive and emotional effects of OT in the group of 68 subjects aged between 50 and 88 years ( = 62.8 ± 8. Read More

Trapped by a first hypothesis: How rudeness leads to anchoring.

J Appl Psychol 2021 Jun 10. Epub 2021 Jun 10.

Department of Anesthesiology, Thomas Jefferson University Hospital.

In this article we explore the effect of encounters with rudeness on the tendency to engage in anchoring, one of the most robust and widespread cognitive biases. Integrating the self-immersion framework with the selective accessibility model (SAM), we propose that rudeness-induced negative arousal will narrow individuals' perspectives in a way that will make anchoring more likely. Additionally, we posit that perspective taking and information elaboration will attenuate the effect of rudeness on both negative arousal and subsequent anchoring. Read More
