Internet-based cognitive assessment tool: Sensitivity and validity of a new online cognition screening tool for patients with bipolar disorder.

J Affect Disord 2021 Apr 27;289:125-134. Epub 2021 Apr 27.

Digital Health Section, Department of Health Technology, Technical University of Denmark, Kongens Lyngby, Denmark; Copenhagen Center for Health Technology, Technical University of Denmark, Kongens Lyngby, Denmark.

Background: The International Society for Bipolar Disorders Targeting Cognition Task Force recommends the Screen for Cognitive Impairment in Psychiatry (SCIP) to screen for cognitive impairment in bipolar disorder. However, SCIP must be administered by a healthcare professional, which is often impossible due to time and resource constraints. Web-based, self-administered cognition screening tools may enable assessment and monitoring of patients' cognition at a much larger scale to a reduced cost. Read More

Compr Psychiatry 2021 Apr 30;108:152242. Epub 2021 Apr 30.

Cornell Center for Research on End-of-Live Care, 321 Lasdon House, 420 East 70(th) Street, Weill Cornell Medicine, NY, New York 10021, United States of America; Department of Medicine, Division of Geriatrics and Palliative Medicine, Baker Pavilion 14(th) Floor, East 68(th) Street, Weill Cornell Medicine, NY, New York 10021, United States of America. Electronic address:

Background: Several studies have shown that interpersonal dependency is a risk factor for prolonged grief disorder (PGD), a disorder that has been recently approved by the American Psychiatric Association Assembly for inclusion in the Diagnostic and Statistical Manual of Mental Disorders-5-Text Revision (DSM-5-TR). Nevertheless, it remains unclear whether this relationship is independent of depression, which may also be related to both loss and interpersonal dependency. Furthermore, anaclitic dependency (maladaptive and immature) compared to relatedness (more adaptive and mature) dependency, and the relationships between these types of dependency and PGD, have not been examined.

Evaluating Ineffective Treatments: A Proposed Model for Discussing Futility in Psychiatric Illness.

Harv Rev Psychiatry 2021 May-Jun 01;29(3):240-245

From the Cleveland Clinic Foundation, Cleveland, OH (Dr. Coulter); Louis Stokes Cleveland VA Medical Center, Cleveland, OH (Dr. Schuermeyer); PrairieCare Medical Group Southern Minnesota, Rochester, MN (Dr. Sola).

Background: Treatment futility and terminality discussions arise rarely in psychiatric practice, frequently instilling apprehension, as there is little written that defines these terms in relation to mental illness. It therefore remains uncertain how to deal with cases that are refractory to multimodal interventions and that demonstrate limited improvement or even a worsening trajectory. Any viable solution needs to respect patient autonomy and maintain both beneficence and nonmaleficence, while taking into account the strained resources of the mental health care system as a whole.

The Potential Use of Peripheral Blood Mononuclear Cells as Biomarkers for Treatment Response and Outcome Prediction in Psychiatry: A Systematic Review.

Mol Diagn Ther 2021 May 12. Epub 2021 May 12.

Faculty of Medicine and Health Sciences, Collaborative Antwerp Psychiatric Research Institute (CAPRI), University of Antwerp, R3.22, Building R, Campus Drie Eiken, Universiteitsplein 1, 2610, Antwerp, Belgium.

Background: Psychiatric disorders have a major impact on the global burden of disease while therapeutic interventions remain insufficient to adequately treat a large number of patients. Regrettably, the efficacy of several psychopharmacological treatment regimens becomes apparent only after 4-6 weeks, and at this point, a significant number of patients present as non-responsive. As such, many patients go weeks/months without appropriate treatment or symptom management. Read More

Inferring Thalamocortical Monosynaptic Connectivity In-Vivo.

J Neurophysiol 2021 May 12. Epub 2021 May 12.

Coulter Department of Biomedical Engineering, Georgia Institute of Technology, United Statesgrid.213917.f.

As the tools to simultaneously record electrophysiological signals from large numbers of neurons within and across brain regions become increasingly available, this opens up for the first time the possibility of establishing the details of causal relationships between monosynaptically connected neurons and the patterns of neural activation that underlie perception and behavior. Although recorded activity across synaptically connected neurons has served as the cornerstone for much of what we know about synaptic transmission and plasticity, this has largely been relegated to ex-vivo preparations that enable precise targeting under relatively well-controlled conditions. Analogous studies in-vivo, where image-guided targeting is often not yet possible, rely on indirect, data-driven measures, and as a result such studies have been sparse and the dependence upon important experimental parameters has not been well studied.

The diagnostic competence of Glial Fibrillary Acidic Protein in mild traumatic brain injury and its prognostic value in patient recovery.

Turk Neurosurg 2020 Jul 6. Epub 2020 Jul 6.

Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran.

Aim: Aim: In clinical assessments and literature conducted on TBI, the mild TBI is less studied, because the initial symptoms are non-specific and subjective, and have overlap with psychological disorders. Glial Fibrillary Acidic Protein (GFAP) is a protein expressed by most of the abundant cells of the CNS. Therefore, this paper attempted to show whether the GFAP levels are significantly higher in the serum of patients with mild traumatic brain injury Material and Methods: The level of serum GFP was measured in 176 patients suffering from brain trauma.

Gender Moderates the Association Between Exposure to Interpersonal Violence and Intermittent Explosive Disorder Diagnosis.

J Interpers Violence 2021 May 12:8862605211013951. Epub 2021 May 12.

McLean Hospital, Belmont, MA, USA.

Exposure to interpersonal violence (EIV) is a prevalent risk-factor for aggressive behavior; however, it is unclear whether the effect of EIV on clinically significant aggressive behavior is similar across gender. We examined whether gender moderates the association between experiencing and witnessing interpersonal violence and the diagnosis of intermittent explosive disorder (IED). We also examined potential pathways that might differentially account for the association between EIV and IED in men and women, including emotion regulation and social information processing (SIP).

Lactoferrin for Mental Health: Neuro-Redox Regulation and Neuroprotective Effects across the Blood-Brain Barrier with Special Reference to Neuro-COVID-19.

J Diet Suppl 2021 May 12:1-35. Epub 2021 May 12.

N-terminus Research Laboratory, Yorba Linda, California, USA.

Overall mental health depends in part on the blood-brain barrier, which regulates nutrient transfer in-and-out of the brain and its central nervous system. Lactoferrin, an innate metal-transport protein, synthesized in the substantia nigra, particularly in dopaminergic neurons and activated microglia is vital for brain physiology. Lactoferrin rapidly crosses the blood-brain barrier receptor-mediated transcytosis and accumulates in the brain capillary endothelial cells. Read More

Interpreting the role of the striatum during multiple phases of motor learning.

FEBS J 2021 May 11. Epub 2021 May 11.

Departments of Psychiatry, Neurology, Pharmacology, Biology, Columbia University: Division of Molecular Therapeutics, New York State Psychiatric Institute, New York, NY, USA, 10032.

The synaptic pathways in the striatum are central to basal ganglia functions including motor control, learning, and organization, action selection, the acquisition of motor skills, cognitive function, and emotion. Here we review the role of the striatum and its connections in motor learning and performance. The development of new techniques to record neuronal activity and animal models of motor disorders using neurotoxin, pharmacological, and genetic manipulations are revealing pathways that underlie motor performance and motor learning, as well as how they are altered by pathophysiological mechanisms.

Characterizing the role of early alcohol re-exposure in associations of prenatal alcohol exposure with adolescent alcohol outcomes.

Alcohol Clin Exp Res 2021 May 11. Epub 2021 May 11.

Syracuse University, Department of Psychology, Syracuse, NY, USA.

Background: Prenatal alcohol exposure has been linked to a host of negative outcomes, although it remains largely unknown whether prenatal exposure leads to earlier age of alcohol use initiation and/or exacerbates early alcohol initiation. The current study examined whether adolescents exposed to heavy drinking during gestation began drinking earlier than their non-exposed peers and whether earlier age of alcohol re-exposure in adolescence exacerbated associations with alcohol outcomes.

Methods: Adolescents (17 years of age; 57% female; 96% White) from a longitudinal, population-based cohort study, the Avon Longitudinal Study of Parents and Children (ALSPAC), reported on their age at first whole drink and alcohol behaviors. Read More
