Sub-cellular population imaging tools reveal stable apical dendrites in hippocampal area CA3.

Apical and basal dendrites of pyramidal neurons receive anatomically and functionally distinct inputs, implying compartment-level functional diversity during behavior. To test this, we imaged in vivo calcium signals from soma, apical dendrites, and basal dendrites in mouse hippocampal CA3 pyramidal neurons during head-fixed navigation. To capture compartment-specific population dynamics, we developed computational tools to automatically segment dendrites and extract accurate fluorescence traces from densely labeled neurons.

Nitrous oxide exerts rewarding effect via regulating D1 receptor and BDNF pathway in ventral tegmental area-nucleus accumbens dopamine circuit.

Recreational use of nitrous oxide (NO) has risen dramatically over the past decades. This study aimed to examine its rewarding effect and the underlying mechanisms. The exposure of mice to a subanesthetic concentration (20%) of NO for 30 min for 4 consecutive days paired with NO in the morning and paired with the air in the afternoon produced apparent rewarding behavior in the conditioned place preference (CPP) paradigm.

A network-based analysis anticipates time to recovery from major depression revealing a plasticity by context interplay.

Predicting disease trajectories in patients with major depressive disorder (MDD) can allow designing personalized therapeutic strategies. In this study, we aimed to show that measuring patients' plasticity - that is the susceptibility to modify the mental state - identifies at baseline who will recover, anticipating the time to transition to wellbeing. We conducted a secondary analysis in two randomized clinical trials, STAR*D and CO-MED.

Exploring when to exploit: the cognitive underpinnings of foraging-type decisions in relation to psychopathy.

Impairments in reinforcement learning (RL) might underlie the tendency of individuals with elevated psychopathic traits to behave exploitatively, as they fail to learn from their mistakes. Most studies on the topic have focused on binary choices, while everyday functioning requires us to learn the value of multiple options. In this study, we evaluated the cognitive correlates of naturalistic foraging-type decision-making and their electrophysiological signatures in a community sample (n = 108) with varying degrees of psychopathic traits.

One state's journey with a reflective supervision professional development series: Development, implementation, and adaptation.

Reflective supervision (RS) has been viewed as best practice and is therefore incorporated-and often mandated-as a key feature of many relationship-based infant and early childhood serving programs. To promote the implementation of high-quality RS for infant and early childhood professionals, it is critical that a focus is placed on how infant and early childhood professionals are trained to build RS capacities. To this end, we describe Rhode Island, United States's journey developing, implementing, and iteratively adapting an RS professional development series.

Evaluating pathogenicity of variants of unknown significance in APP, PSEN1, and PSEN2.

Autosomal dominant Alzheimer's disease (ADAD) is driven by rare variants in APP, PSEN1, and PSEN2. Although more than 200 pathogenic variants in these genes are known to cause ADAD, other variants are benign, may act as risk factors, or may even reduce Alzheimer's disease risk (e.g.

Problem Adaptation Therapy for Older Adults with Chronic Pain and Negative Emotions in Primary Care (PATH-Pain): A Randomized Clinical Trial.

Objective: To test the efficacy of Problem Adaptation Therapy for Pain (PATH-Pain) versus Usual Care (UC) in reducing pain-related disability, pain intensity, and depression among older adults with chronic pain and negative emotions.

Design: RCT assessing the between-group differences during the acute (0-10 weeks) and follow-up (weeks 11-24) phase of treatment.

Setting: A geriatrics primary care site.

Evaluating Response to a Cognitive Behavioural Therapy for Psychosis-Informed Family Intervention at Variable Duration of a Psychotic Illness.

Objective: Early intervention in psychosis is associated with favourable outcomes. We investigated whether loved ones' illness duration moderated caregiver outcomes following a Cognitive Behavioural Therapy-informed Family Intervention for psychosis (FIp).

Methods: We conducted a secondary analysis of measures of FIp participants' depression and anxiety symptoms, caregiver appraisals, expressed emotion and foundational psychotherapeutic competencies at pre-, post- and 4-month follow-up.

Community and Hospital Healthcare Use by Adults With and Without Intellectual and Developmental Disabilities in Ontario, Canada, During the First 2 Years of the COVID-19 Pandemic.

Background: This study describes the proportion of Ontario adults with and without intellectual and developmental disabilities (IDD) who used community- and hospital-based healthcare in the first 2 years of the pandemic compared with the year pre-COVID-19.

Methods: Linked health administrative databases identified 87 341 adults with IDD and also adults without IDD living in Ontario, Canada. For each cohort, counts and proportions of adults who used different types of healthcare services were reported for the pre-COVID-19 year (16 March 2019 to 14 March 2020) and the first two COVID-19 years (15 March 2020 to 14 March 2021 and 15 March 2021 to 14 March 2022).

Neonatal unit admission and offspring mental health trajectories across childhood and adolescence: a nationally representative UK cohort study.

Objective: To investigate the associations between neonatal unit admission (NNU) and subsequent emotional and behavioural difficulties during childhood and adolescence.

Design: Longitudinal general population cohort study.

Setting: The Millennium Cohort Study: nationally representative UK-based cohort.

[Legal requirements for information and their influence on patient satisfaction].

The German Patientenrechtegesetz defines, among other things, medical obligations in connection with the provision of information. To date, the extent to which these legal requirements also influence patient satisfaction with information has not been investigated in Germany.The study employed an anonymized patient survey on satisfaction with information, which was recorded using a validated 10-item questionnaire.

Guided Self-Help vs Group Treatment for Children With Obesity: A Randomized Clinical Trial.

Background And Objectives: Family-based behavioral treatment (FBT) for children with obesity is provided in weekly parent and child groups over 6 months. A guided self-help FBT program (gshFBT) is provided to the dyad in short meetings. Both interventions provide the same content; however, gshFBT provides this content in less time (FBT = 23 hours, gshFBT = 5.

Elevated plasma Tau-PT217 linked to decreased hippocampal functional connectivity in patients with knee osteoarthritis.

Background: Osteoarthritis is associated with a higher risk of developing dementia, though the underlying biological mechanisms have remained unclear. Recent studies suggest that blood phosphorylated tau proteins, particularly Tau-PT217, are sensitive biomarkers capable of detecting cognitive decline in its early stages, making it useful for early diagnosis of Alzheimer's disease and other forms of cognitive impairment.

Methods: In this study, we investigated the plasma phosphorylated tau protein levels (Tau-PT217 and Tau-PT181), hippocampus functional connectivity, and cognitive function in people with knee osteoarthritis compared to age and gender matched pain-free controls.

The brain-gut microbiota network (BGMN) is correlated with symptom severity and neurocognition in patients with schizophrenia.

The association between the human brain and gut microbiota, known as the "brain-gut-microbiota axis", is involved in the neuropathological mechanisms of schizophrenia (SZ); however, its association patterns and correlations with symptom severity and neurocognition are still largely unknown. In this study, 43 SZ patients and 55 normal controls (NCs) were included, and resting-state functional magnetic resonance imaging (rs-fMRI) and gut microbiota data were acquired for each participant. First, the brain features of brain images and functional brain networks were computed from rs-fMRI data; the gut features of gut microbiota abundance and the gut microbiota network were computed from gut microbiota data.

Sexual identity, sexual behavior, and drug use behaviors among people who use drugs in the rural U.S.

Introduction: People who use drugs (PWUD) are at risk of HIV infection, but the frequency and distribution of transmission-associated behaviors within rural communities is not well understood. Further, while interventions designed to more explicitly affirm individuals' sexual orientation and behaviors may be more effective, descriptions of behavior variability by orientation are lacking. We sought to describe how disease transmission behaviors and overdose risk vary by sexual orientation and activity among rural PWUD.

What are the levels and interactions of neuroligin-1, neuroligin-3, and inflammatory cytokines (IL-6, IL-8) in children diagnosed with autism spectrum disorder?

Autism spectrum disorder (ASD) is characterized by deficits in social interaction, restricted interests, and repetitive behaviors. Several genes, including synaptic proteins and environmental risk factors, play a role in the etiology of autism. We aimed to evaluate the relationship between neuroligin-1 (NLGN-1) and neuroligin-3 (NLGN-3) levels, which are neuronal cell adhesion molecules (CAMs), and inflammatory cytokine (IL-6, IL-8) levels with disease severity and symptom clusters and with each other in children with ASD.

Topography of putative bi-directional interaction between hippocampal sharp-wave ripples and neocortical slow oscillations.

Systems consolidation relies on coordination between hippocampal sharp-wave ripples (SWRs) and neocortical UP/DOWN states during sleep. However, whether this coupling exists across the neocortex and the mechanisms enabling it remains unknown. By combining electrophysiology in mouse hippocampus (HPC) and retrosplenial cortex (RSC) with wide-field imaging of the dorsal neocortex, we found spatially and temporally precise bi-directional hippocampo-neocortical interaction.

Aging Disparities in Ostomy Surgery.

Introduction: Little is known about the association between age and fecal ostomy surgery trends over time. We aim to 1) determine the rate of fecal ostomy operations over time and 2) compare rates of colostomy formation between patients older and younger than 65 y.

Materials And Methods: Retrospective multi-institutional cohort study of patients ≥18 y who underwent colorectal resection between 2003 and 2014 using the Nationwide Inpatient Sample database.

Cancer-specific utility instrument for health economic evaluations: A synopsis of the EORTC QLU-C10D user manual and current validity evidence.

The European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Utility - Core 10 Dimensions (QLU-C10D) adds a preference-based scoring algorithm to the EORTC measurement portfolio. It is built on the most widely used health-related quality of life (HRQoL) measure in oncology, the EORTC Quality of Life Questionnaire - Core 30 (QLQ-C30), allowing for the calculation of both HRQoL profiles and health utilities. This is an important advancement for integrating cancer-specific values into health economic evaluations and decision making, offering greater content validity and statistical power than some generic measures.

Psychiatric disorders in adolescent and young adult cancer survivors in Korea.

Background: Although adolescent and young adult (AYA) cancer survivors have an increased risk of psychiatric disorders, limited evidence has been suggested. We aimed to determine the risk of psychiatric disorders among AYA cancer survivors.

Materials And Methods: A retrospective population-based cohort study based on the Korea National Health Insurance Service database was carried out.

Contextual differences in parent-child interactions: A study on toddlers at elevated likelihood of autism and their mothers.

Parent-child interactions are important for children's emotional and behavioral development. In autism research, parent-child interactions are typically observed during free play. Yet, studies outside the autism field underscored the importance of observing parent-child interactions during other contexts, as parents' behaviors may depend on the context, and different contexts may reveal different relationships between parents' and children's behaviors.

Nutritional interventions in depression: The role of vitamin D and omega-3 fatty acids in neuropsychiatric health.

Background: Depression is a pervasive mental health disorder with complex etiologies involving neurotransmitter imbalances, inflammation, and hormonal dysregulation. Emerging evidence highlights the significance of nutritional interventions in improving depressive symptoms.

Objective: This review explores the mechanisms of action and clinical applications of Vitamin D and Omega-3 fatty acids in managing depression, providing insights into their potential therapeutic roles.

Involuntary autobiographical memories as a transdiagnostic factor in mental disorders.

Involuntary autobiographical memories are memories of personal events that come to mind with no preceding retrieval attempts. They have been studied broadly in autobiographical memory for decades and shown to be common and mostly positive in everyday life. Clinical literature has focused on negative intrusive memories of stressful events and tended to neglect other forms of involuntary autobiographical memories.

Changes to social and healthcare providers support in the perinatal period: Impact on coping strategies, depression and anxiety.

Background: During the perinatal period, risk of depression and anxiety (D&A) increases. As in other crisis events, the COVID-19 pandemic, imposed social distancing measures, diminished social support and changes in perinatal healthcare provision which heightened this risk. This study aimed to examine how changes in social and healthcare provider support during the pandemic affected coping strategies and depression and anxiety symptoms (D&As) among perinatal women.
