Pseudoaneurysm Formation after Stereoencephalography for Epilepsy.

Introduction: Stereoencephalography (SEEG) has emerged as the most common technique for invasive monitoring as part of the preoperative workup for epilepsy surgery. The use of intracranial implants has the potential for vascular injury giving rise to pseudoaneurysm, followed by unpredictable, delayed hemorrhage. Confirmed cases of post-SEEG pseudoaneurysm, as well as suspected cases involving delayed hemorrhage after explanation, are very rare and have not allowed identification of the inciting cause.

Influence of Mother-Father Relationship on Perceived Stress among Black Pregnant Women.

Background: Perceived stress during pregnancy has been associated with adverse maternal health and birth outcomes. Compared to White pregnant women, Black pregnant women in the United States report higher levels of perceived stress and experience higher rates of maternal mortality and preterm birth. Mother-father relationship has been associated with perceived stress among pregnant women, though literature among Black pregnant women is limited.

Boosting Psychotherapy With Noninvasive Brain Stimulation: The Whys and Wherefores of Modulating Neural Plasticity to Promote Therapeutic Change.

The phenomenon of neural plasticity pertains to the intrinsic capacity of neurons to undergo structural and functional reconfiguration through learning and experiential interaction with the environment. These changes could manifest themselves not only as a consequence of various life experiences but also following therapeutic interventions, including the application of noninvasive brain stimulation (NIBS) and psychotherapy. As standalone therapies, both NIBS and psychotherapy have demonstrated their efficacy in the amelioration of psychiatric disorders' symptoms, with a certain variability in terms of effect sizes and duration.

Frequency-dependent assembly processes determine the coexistence and relative abundance of tropical plant species.

Testing the extent to which ecological communities are structured by deterministic (niche-based) assembly processes, resulting in predictable species abundance and composition, is a fundamental goal of ecology. Here we use a 10-year dataset of 55,156 lianas comprising 86 species in an old-growth tropical forest in Panama to test whether community assembly is consistent with niche-based assembly processes. We find that species diversity and community composition was maintained because species conformed to four general requirements of coexistence theory: (1) species have negative conspecific frequency-dependent feedback that control their local population size; (2) species have a stronger negative effect on their own population than that of heterospecifics; (3) the equilibrium frequencies of species correspond to their relative abundance; and (4) species have positive invasibility.

Epigenetic Modifications and Neuroplasticity in the Pathogenesis of Depression: A Focus on Early Life Stress.

Major depressive disorder (MDD) is a debilitating mental illness, and it is considered to be one of the leading causes of disability globally. The etiology of MDD is multifactorial, involving an interplay between biological, psychological, and social factors. Early life represents a critical period for development.
