Drivers of resting-state fMRI heterogeneity in traumatic brain injury across injury characteristics and imaging methods: a systematic review and semiquantitative analysis.

Traumatic brain injury (TBI) is common and costly. Although neuroimaging modalities such as resting-state functional MRI (rsfMRI) promise to differentiate injured from healthy brains and prognosticate long-term outcomes, the field suffers from heterogeneous findings. To assess whether this heterogeneity stems from variability in the TBI populations studied or the imaging methods used, and to determine whether a consensus exists in this literature, we performed the first systematic review of studies comparing rsfMRI functional connectivity (FC) in patients with TBI to matched controls for seven canonical brain networks across injury severity, age, chronicity, population type, and various imaging methods.

CARE4Kids Study: Endophenotypes of Persistent Post-Concussive Symptoms in Adolescents: Study Rationale and Protocol.

Treatment of youth concussion during the acute phase continues to evolve, and this has led to the emergence of guidelines to direct care. While symptoms after concussion typically resolve in 14-28 days, a portion (∼20%) of adolescents endorse persistent post-concussive symptoms (PPCS) beyond normal resolution. This report outlines a study implemented in response to the National Institute of Neurological Diseases and Stroke call for the development and initial clinical validation of objective biological measures to predict risk of PPCS in adolescents.

Characteristics of Pediatric Mild Traumatic Brain Injury and Recovery in a Concussion Clinic Population.

Importance: Pediatric mild traumatic brain injury (TBI) and concussion are a public health challenge with up to 30% of patients experiencing prolonged recovery. Pediatric patients presenting to concussion clinics often have ongoing impairments and may be at increased risk for persistent symptoms. Understanding this population is critical for improved prognostic estimates and optimal treatment.

Embracing Diversity: the Complexities of Reckoning and Accepting Otherness.

Many within society are working to address issues of otherness and the ways people discriminate against others in various ways such as racism, sexism, ageism, ableism, and classism. In this paper we do not pretend to offer a solution, but we wish to add to the understanding of the complexities at play. We consider the importance of how our developmental negotiation and resolution of early childhood processes of separation and individuation incline us to adopt and move between four different existential-relational positions, each of which colors how we experience ourself in relation to our own self and to other selves.

The Varieties of Procrastination: with Different Existential Positions Different Reasons for it.

Instead of considering procrastination as a unitary construct we argue that it takes different forms and has multiple explanations and determinants. While it is fair to consider procrastination a cognitive focusing issue, we posit that the motivational sources for this vary depending on where someone can be located with regard to the "existential" developmental positions that have been explicated over many years by Object Relations clinical theorists: the autistic-contiguous, paranoid-schizoid, depressive, and transcendental. These positions generate different understandings of what motivates procrastination and in turn, effects the interventions we offer.

Deception within adolescent sexual conduct.

Deception is presented as a "design to defeat a design" (Thompson 1986, p 64) where one actor purposefully changes the environment with the intention on generating a less adaptive response from another actor. The shared context combined with the indeterminacy of meanings makes deception not only possible, but also an important strategy for adaptation. In this regard not all deception temporarily causes individuals to reorganize their meaning making hierarchy around the changes made by the other party.
