Background: Although multiple qualitative studies have explored participants' experiences of behavioural activation (BA) for unipolar depression, none have investigated the experiences of BA in people with bipolar depression. This is of particular interest because qualitative studies concerning the experience of receiving therapy can help inform the theory of change underpinning the intervention.

Aim: The purpose of this study was to explore the experiences and perspectives of individuals with bipolar disorder who received a course of one-to-one BA for bipolar depression.

Background: There are two approaches for endobronchial ultrasound (EBUS) training: the traditional apprenticeship approach involving 'see one, do one, teach one', and the computer-based simulation approach. In the traditional approach, the trainee learns under direct supervision from an expert preceptor while performing on patients. In the latter approach, trainees use a high-fidelity bronchoscopy simulator, undertake a skills assessment exam (Endobronchial Ultrasound Skills and Task Assessment Tool (EBUS-STAT)), and receive supervised patient-based training from experienced clinicians.

Augmented Depression Therapy (ADepT) is an individual psychotherapy for depression, which has been shown to be effective in the general adult population. A randomised multiple baseline case series evaluated the feasibility, acceptability, and effectiveness of ADepT in young adults (aged 20-24). Eleven depressed young adults were recruited from a UK university wellbeing service to receive ADepT during the COVID-19 pandemic, with outcomes evaluated relative to pre-specified continuation targets.

Objective: Mindfulness-based cognitive therapy (MBCT) is a viable alternative to maintenance antidepressant medication (M-ADM) to reduce risk of relapse/recurrence (RR) in recurrent depression, but its mechanism of action is not yet fully articulated. This secondary analysis of the PREVENT trial examined if MBCT with support to taper medication (MBCT-TS) reduces risk of RR in part by enhancing positive affect (PA).

Method: In a single-blind, parallel, group randomized controlled trial, adults with ≥3 prior depressive episodes, but not currently in episode and who were taking M-ADM, were randomized to receive either MBCT-TS or ongoing maintenance M-ADM.

Article Synopsis
  • * Isotonic normal saline is standard for initial fluid resuscitation, but balanced solutions can help DKA resolve quicker; continuous IV insulin is preferred after stabilizing fluids and electrolytes.
  • * The review warns against rapid hyperglycemia correction leading to cerebral edema, recommends close monitoring of electrolytes, and suggests that early oral nutrition can shorten hospital stays; intubation is preferred for respiratory failure management, while routine sodium bicarbonate use is generally discouraged.

The Neuronal alpha-Synuclein Disease (NSD) biological definition and Integrated Staging System (NSD-ISS) provide a research framework to identify individuals with Lewy body pathology and stage them based on underlying biology and increasing degree of functional impairment. Utilizing data from the PPMI, PASADENA, and SPARK studies, we developed and applied biologic and clinical data-informed definitions for the NSD-ISS across the disease continuum. Individuals enrolled as Parkinson's disease, Prodromal, or Healthy Controls were defined and staged based on biological, clinical, and functional anchors at baseline.

Article Synopsis
  • The Neuronal alpha-Synuclein Disease (NSD) and its Integrated Staging System (NSD-ISS) aim to identify and classify individuals with Lewy body pathology according to biological and functional factors.
  • Data from multiple studies reveal that a significant percentage of participants with Parkinson’s disease (PD) were classified as S+ (consistent with NSD), indicating a strong link between biological markers and disease staging.
  • Findings suggest that the baseline stage of individuals influences the timeline for progression to significant clinical outcomes, highlighting the need for further validation of the staging anchors in longer-term studies.

Hexagonal boron nitride (BN), a well-known member of 2D materials, has a structure similar to graphene and is often referred to as white graphene. Despite its unique physical and chemical properties for energy storage applications, there have been very few studies on how BN stores anion carriers. Herein, the hybrid architecture and anion storage mechanism of BN nanosheets for high-performance hybrid energy storage full cells based on dual-ion and Zinc (Zn) alkaline systems is demonstrated.

Non-covalent interactions play an important role for the framework formation of two-dimensional covalent organic frameworks. Until now, π-π interactions and hydrogen bonding are the main reported forces facilitating the stacking of framework layers. Here, we present a two-dimensional anionic covalent organic framework based on tetratopic borate linkages, where layers are connected by ionic interactions between the linkage site and counter cations.

Navigation requires integrating sensory information with a stable schema to create a dynamic map of an animal's position using egocentric and allocentric coordinate systems. In the hippocampus, place cells encode allocentric space, but their firing rates may also exhibit directional tuning within egocentric or allocentric reference frames. We compared experimental and simulated data to assess the prevalence of tuning to egocentric bearing (EB) among hippocampal cells in rats foraging in an open field.

Introduction: Tau-positron emission tomography (PET) outcome data of patients with Alzheimer's disease (AD) cannot currently be meaningfully compared or combined when different tracers are used due to differences in tracer properties, instrumentation, and methods of analysis.

Methods: Using head-to-head data from five cohorts with tau PET radiotracers designed to target tau deposition in AD, we tested a joint propagation model (JPM) to harmonize quantification (units termed "CenTauR" [CTR]). JPM is a statistical model that simultaneously models the relationships between head-to-head and anchor point data.

Minimal experiments, such as head-fixed wheel-running and sleep, offer experimental advantages but restrict the amount of observable behavior, making it difficult to classify functional cell types. Arguably, the grid cell, and its striking periodicity, would not have been discovered without the perspective provided by free behavior in an open environment. Here, we show that by shifting the focus from single neurons to populations, we change the minimal experimental complexity required.
