Routine laboratory parameters to support decision on parenteral nutrition in palliative care.

Introduction: Parenteral nutrition (PN) is widely used in palliative care (PC), but there is limited evidence to support its use at the end of life (EOL). This aim of this was to investigate the relationship between routine laboratory parameters and survival in patients receiving PN, and to develop a decision tree model to support clinicians decide whether to start or forgo PN.

Methods: The laboratory parameters of 113 patients with advanced diseases who were admitted to a specialized palliative care unit (PCU) were analyzed at two points in time: T0 = before PN, T1 = two weeks after initiation of PN.

Machine learning models predict PTSD severity and functional impairment: A personalized medicine approach for uncovering complex associations among heterogeneous symptom profiles.

Objective: Posttraumatic stress disorder (PTSD) is a debilitating psychiatric illness, experienced by approximately 10% of the population. Heterogeneous presentations that include heightened dissociation, comorbid anxiety and depression, and emotion dysregulation contribute to the severity of PTSD, in turn, creating barriers to recovery. There is an urgent need to use data-driven approaches to better characterize complex psychiatric presentations with the aim of improving treatment outcomes.

The Effects of Occupational Complexity on Late Life Cognition in ACTIVE: Examining the Mediating and Moderating Effects of Race.

This article sought to determine (1) whether occupational complexity (OC) explains individual differences in cognition at baseline, (2) whether this relationship is differentially related to cognition by Black/White race, and (3) whether OC mediates some or all of the Black/White race-related variance in late life cognition. 2371 participants from the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study reported longest held jobs and received OC ratings based on a factor analysis of 63 variables from the Dictionary of Occupational Titles. We found that multiple dimensions of OC are related to cognition, but there were relatively few Black/White differences in these associations.

Effects of Cognitive Training on Alzheimer's Disease and Related Dementias: The Moderating Role of Social Determinants of Health.

We examined whether social determinants of health (SDoH) are associated with Alzheimer's disease and related dementias (ADRD) risk and the effects of cognitive training over a 20-year follow-up period. Data were obtained from 1605 participants in ACTIVE. SDoH measures were created using baseline data at the individual and neighborhood level.

Associations Between Body Mass Index and Cognitive Change in the ACTIVE Study: Variations by Race and Social Determinants of Health.

The current study examines relationships between Body Mass Index (BMI) and cognitive performance and change in processing speed, memory, and reasoning, while accounting for variations by race and the influence of social determinants of health. Secondary data analysis of the Advanced Cognitive Training for Independent and Vital Elderly (ACTIVE) study, which included participants who self-identified as African American or Black ( = 728) and White ( = 2028). Latent growth curve modeling was used to assess study aims.

Greater socioenvironmental risk factors and higher chronic pain stage are associated with thinner bilateral temporal lobes.

Introduction: Previous research indicates ethnic/race group differences in pain and neurodegenerative diseases. Accounting for socioenvironmental factors reduces ethnic/race group differences in clinical and experimental pain. In the current study sample, we previously reported that in individuals with knee pain, ethnic/race group differences were observed in bilateral temporal lobe thickness, areas of the brain associated with risk for Alzheimer's disease, and related dementias.

Effect of typical alcohol use and expectancies on the social manipulation of drinking behavior in a virtual bar pilot study.

Background: Recent work indicates that increasing the drinking rate of a virtual bar-goer (VB) increases the rate of drinking for participants in a virtual reality (VR) bar environment. Here, we test the hypothesis that biopsychosocial factors including typical drinking pattern and expectancy that alcohol enhances social interactions would moderate this effect.

Methods: We assessed the drinking topography (DT) of participants (N=20) in a VR environment with a programmable VB during two testing sessions: one with a fast-drinking VB (30-60s sip interval) and one in which the VB drank slowly (60-120s sip interval).

Factors associated with quality of life for cystic fibrosis family caregivers.

Cystic Fibrosis (CF) is a genetic and chronic disease affecting 32,100 people in the United States as of 2021, with a life expectancy of 56 years for people with CF (PwCF) born between 2018 and 2022. While there is extensive literature about cystic fibrosis, there are few studies examining the complexity and challenges experienced by family caregivers for PwCF. The aim of this study was to examine the Caregiver Quality of Life Cystic Fibrosis (CQOLCF) scale using data (N = 217) from two separate studies that used the scale to determine if its items represent multiple factors relevant to CF family caregiver QoL.

Executive functions and daily functioning in myotonic dystrophy type 1 ecological assessment with virtual reality.

Central nervous system dysfunction is characteristic of patients with myotonic dystrophy type 1 (DM1). Although no consensus exists regarding the exact cognitive profile of these patients, executive dysfunction has been suggested to play a role. Due to the impact of executive functions on daily performance, this study aimed to describe executive functioning in an ecological manner and to analyze its impact - and that of other clinical variables - on the functional performance of DM1 patients.

Improved Post-Traumatic Stress Disorder Symptoms and Related Sleep Disturbances after Initiation of Medical Marijuana Use: Evidence from a Prospective Single Arm Pilot Study.

Introduction: Post-traumatic stress disorder (PTSD) is a debilitating disorder experienced by a subgroup of individuals following a life-threatening trauma. Several US states have passed laws permitting the medical use of marijuana (MMJ) by individuals with PTSD, despite very little scientific indication on the appropriateness of marijuana as a therapy for PTSD. This prospective pilot study of adults with confirmed PTSD in Florida (FL) investigated whether PTSD symptoms, sleep quality, affect, and general physical and mental health/well-being improved post-initiation of MMJ treatment.

Perioperative Extracellular Brain Free-Water Changes for Older Adults Electing Total Knee Arthroplasty with General versus Spinal Anesthesia: A Pilot Study.

Background: Recent research shows that older adults electing to undergo total knee arthroplasty with general anesthesia have a pre- to postoperative acute increase in molecular free-water within their cerebral white matter. It is unknown if this change is similar for individuals who elect spinal anesthesia methods.

Objective: To explore white matter microstructural changes in a pilot sample of older adults undergoing total knee arthroplasty and receiving general or spinal anesthesia.

Visuoconstructional impairment in DM1: exploring underlying cognitive processes through the Rey complex figure.

Introduction: Among the cognitive difficulties shown by myotonic dystrophy type 1 (DM1) patients, visuoconstructional impairment - specifically measured with the Rey-Osterrieth Complex Figure Test (RCFT) - is particularly notable. This study aimed to analyze the performance of DM1 patients and healthy controls (HC) in the RCFT, using different correction systems in order to explore the cognitive processes underlying the poor performance and its associations with other signs and symptoms.

Methods: Data from 66 DM1 patients and 68 HC were included in this study.

Social determinants of health and incident postoperative delirium: Exploring key relationships in the SAGES study.

Background: Examining the associations of social determinants of health (SDOH) with postoperative delirium in older adults will broaden our understanding of this potentially devastating condition. We explored the association between SDOH factors and incident postoperative delirium.

Methods: A retrospective study of a prospective cohort of patients enrolled from June 18, 2010, to August 8, 2013, across two academic medical centers in Boston, Massachusetts.

The influence of hatha yoga on stress, anxiety, and suppression: A randomized controlled trial.

Engaging in yoga may mitigate stress and anxiety in individuals while potentially enhancing one's capacity to manage distractions. Our research aimed to explore the relation between these two outcomes: Can an eight-week yoga program foster distraction suppression, thereby reducing stress and discomfort? To answer this question, we used Hatha Yoga, the most commonly practiced form of yoga. We tested if the intervention improved participants' ability to suppress distractions and selectively decrease self-reported stress and stress reactivity.

Understanding the role of parents' information sharing and withholding on emerging and young adults' caregiving and coping during their parents' advanced cancer.

Emerging and young adult caregivers (EYACs) who provide care to their parents are a hidden, unsupported population of caregivers. Research identifies information sharing or withholding as a key aspect of caregivers' ability to cope and adjust, which may be especially critical when a parent is diagnosed with advanced cancer. The goal of this study was to examine the impact of parent information sharing/withholding on EYACs' caregiving and coping experiences.

Self-perceived problems of Afghan asylum seekers and refugees and their experiences with a short psychological intervention.

Background: The present study examined Afghan asylum seekers' and refugees' self-perceived problems, and their experiences of treatment with an adapted version of the brief transdiagnostic psychological intervention "Problem Management Plus" (aPM+). Specifically, the study explored which problems trouble them most and how these problems influence their daily functioning. Further, it examined how various standardized outcome measures correlate with these subjectively perceived problems.

Management of fraudulent participants in online research: Practical recommendations from a randomized controlled feasibility trial.

Objective: Fraudulent participation is an escalating concern for online clinical trials and research studies and can have a significant negative impact on findings. We aim to shed light on the risk and to provide practical recommendations for detecting and managing such instances.

Methods: The FREED-Mobile (FREED-M) study is an online, randomized controlled feasibility trial to assess a digital early intervention for young people (aged 16-25) in England or Wales with eating problems.

Pet ownership is associated with harmful alcohol use among a cohort of people with HIV: a brief research report.

Research suggests that people with HIV (PWH), who are at high risk for alcohol and substance use, may rely on relationships with pets for companionship and stress relief. There may be common mechanisms underlying both substance use and attachment to pets. The purpose of this brief research report was to compare alcohol and substance use behaviors between pet owners and non-owners among a cohort of PWH.

How is music listening purpose related to stress recovery? - two preliminary studies in men and women.

Introduction: Studies have suggested that listening to music can reduce psychological and biological responses to a stressor. However, it is unclear whether music has the same effect on stress recovery. According to field studies, people commonly use music in daily life for the specific purpose of relaxation.

FaIRClocks: Fair and Interpretable Representation of the Clock Drawing Test for mitigating classifier bias against lower educational groups.

The clock drawing test (CDT) is a neuropsychological assessment tool to evaluate a patient's cognitive ability. In this study, we developed a ir and nterpretable epresentation of drawing tests () to evaluate and mitigate bias against people with lower education while predicting their cognitive status. We represented clock drawings with a 10-dimensional latent embedding using Relevance Factor Variational Autoencoder (RF-VAE) network pretrained on publicly available clock drawings from the National Health and Aging Trends Study (NHATS) dataset.

Music for autism: a protocol for an international randomized crossover trial on music therapy for children with autism.

The notion of a connection between autism and music is as old as the first reported cases of autism, and music has been used as a therapeutic tool for many decades. Music therapy holds promise as an intervention for individuals with autism, harnessing their strengths in music processing to enhance communication and expression. While previous randomized controlled trials have demonstrated positive outcomes in terms of global improvement and quality of life, their reliance on psychological outcomes restricts our understanding of underlying mechanisms.
