ninjaCap: a fully customizable and 3D printable headgear for functional near-infrared spectroscopy and electroencephalography brain imaging.

Accurate sensor placement is vital for non-invasive brain imaging, particularly for functional near-infrared spectroscopy (fNIRS) and diffuse optical tomography (DOT), which lack standardized layouts such as those in electroencephalography (EEG). Custom, manually prepared probe layouts on textile caps are often imprecise and labor intensive. We introduce a method for creating personalized, 3D-printed headgear, enabling the accurate translation of 3D brain coordinates to 2D printable panels for custom fNIRS and EEG sensor layouts while reducing costs and manual labor.

Screening, Assessment, and Pharmacologic Treatment of Mild Cognitive Impairment and Early Alzheimer's Disease: The Role for Monoclonal Antibodies.

The Psychiatric Consultation Service at Massachusetts General Hospital sees medical and surgical inpatients with comorbid psychiatric symptoms and conditions. During their twice-weekly rounds, Dr Stern and other members of the Consultation Service discuss diagnosis and management of hospitalized patients with complex medical or surgical problems who also demonstrate psychiatric symptoms or conditions. These discussions have given rise to rounds reports that will prove useful for clinicians practicing at the interface of medicine and psychiatry.

Optical coherence tomography-based design for a real-time motion corrected scanning microscope.

While two-photon fluorescence microscopy is a powerful platform for the study of functional dynamics in living cells and tissues, the bulk motion inherent to these applications causes distortions. We have designed a motion tracking module based on spectral domain optical coherence tomography which compliments a laser scanning two-photon microscope with real-time corrective feedback. The module can be added to fluorescent imaging microscopes using a single dichroic and without additional contrast agents.

Model of dynamic speckle evolution for evaluating laser speckle contrast measurements of tissue dynamics.

We introduce a dynamic speckle model (DSM) to simulate the temporal evolution of fully developed speckle patterns arising from the interference of scattered light reemitted from dynamic tissue. Using this numerical tool, the performance of laser speckle contrast imaging (LSCI) or speckle contrast optical spectroscopy (SCOS) systems which quantify tissue dynamics using the spatial contrast of the speckle patterns with a certain camera exposure time is evaluated. We have investigated noise sources arising from the fundamental speckle statistics due to the finite sampling of the speckle patterns as well as those induced by experimental measurement conditions including shot noise, camera dark and read noise, and calibrated the parameters of an analytical noise model initially developed in the fundamental or shot noise regime that quantifies the performance of SCOS systems using the number of independent observables (NIO).

Treatment of Electroconvulsive Therapy-Emergent Hypomania and Mania: A Systematic Review of the Literature.

Electroconvulsive therapy (ECT)-emergent hypomania/mania is a clinically significant problem that has lacked evidence-based guidelines for effective management. The aim of this systematic literature review is to compile the current published literature on treating ECT-emergent hypomania/mania to help guide treatment course in patients with unipolar and bipolar depression. MEDLINE/PubMed was searched for studies published from 1980 through August 2020 that evaluated the treatment of ECT-emergent hypomania/mania.

An adaptive optics module for deep tissue multiphoton imaging in vivo.

Understanding complex biological systems requires visualizing structures and processes deep within living organisms. We developed a compact adaptive optics module and incorporated it into two- and three-photon fluorescence microscopes, to measure and correct tissue-induced aberrations. We resolved synaptic structures in deep cortical and subcortical areas of the mouse brain, and demonstrated high-resolution imaging of neuronal structures and somatosensory-evoked calcium responses in the mouse spinal cord at great depths in vivo.

The Psychopharmacology Algorithm Project at the Harvard South Shore Program: An update on management of behavioral and psychological symptoms in dementia.

Geriatric patients with dementia frequently present with agitation, aggression, psychosis, and other behavioral and psychological symptoms of dementia (BPSD). We present an update of our previously published algorithms for the use of psychopharmacologic agents in these patients taking into account more recent studies and findings in meta-analyses, reviews, and other published algorithms. We propose three algorithms: BPSD in an emergent, urgent, and non-urgent setting.

Chronic Imaging of Mouse Brain: From Optical Systems to Functional Ultrasound.

Utilization of functional ultrasound (fUS) in cerebral vascular imaging is gaining popularity among neuroscientists. In this article, we describe a chronic surgical preparation method that allows longitudinal studies and therefore is applicable to a wide range of studies, especially on aging, stroke, and neurodegenerative diseases. This method can also be used with awake mice; hence, the deleterious effects of anesthesia on neurovascular responses can be avoided.

COVID-19 Pandemic: Impact on psychiatric care in the United States.

The World Health Organization declared the coronavirus outbreak a pandemic on March 11, 2020. Infection by the SARS-CoV2 virus leads to the COVID-19 disease which can be fatal, especially in older patients with medical co-morbidities. The impact to the US healthcare system has been disruptive, and the way healthcare services are provided has changed drastically.

What We Know About Massively Multiplayer Online Role-Playing Games.

The fifth edition of the Diagnostic and Statistical Manual of Mental Disorders defines internet gaming disorder without differentiating games from their respective genres, such as first-person shooter versus real-time strategy versus online gaming. Our review of the literature on massively multiplayer online role-playing games (MMORPGs) suggests that MMORPGs are different from other games because they are the most addictive, and therefore deserve to be looked at separately. MMORPGs are internet platforms for online users to interact with each other in a virtual story line.

Opioid use and schizophrenia.

Purpose Of Review: To summarize the current literature regarding comorbid schizophrenia and opioid use disorder (OUD).

Recent Findings: Epidemiological evidence is unclear on whether patients with schizophrenia have a higher rate of OUD. Patients with OUD have been shown to have a higher risk of developing schizophrenia.

Antipsychotics and the microbiota.

Purpose Of Review: The gut microbiota has been speculated to underpin metabolic changes associated with chronic antipsychotic use. The change in the gut microbiota can also cause abnormal absorbtion from the gut into the blood stream (leaky gut syndrome) that can lead to inflammatory reactions, and thus, secondary damage to the brain and central nervous system. Our article aims to highlight relevant research on antipsychotic's effect on the microbiota and to point out future directions.
