Background: Delirium, a sudden and acute state of confusion, is known to be more prevalent in hospitalised older adults with dementia and is associated with lower levels of functioning after the delirium episode; yet, the literature on estimates of delirium prevalence in community-dwelling older adults with dementia is scarce. The aim of this study was to define and determine the frequency of delirium-like symptoms in two different samples of community-dwelling persons living with dementia, as reported by their family caregivers. 'Delirium-like symptoms' is a concept that specifies an occurrence of cognitive and behavioural symptoms, provoking suspicion of delirium, that represent a sudden and unusual deleterious change in a community-dwelling person living with dementia that can be identified by family caregivers and prompt healthcare seeking behaviours.

This secondary data analysis sought to identify characteristics associated with mistreatment among chronic stroke survivors who transition to dementia. We examined baseline data from a multi-time series survey study ( = 453; ) on caregiving experiences influencing dementia family caregivers' abusive or neglectful behaviors. Inferential statistical analysis indicated that baseline mistreatment rates were similar across stroke and non-stroke subgroups, though this finding was not significant.

Introduction: Behavioral and psychological symptoms in dementia (BPSD) are dynamic phenomena with a high amount of intraindividual variability. We applied a multilevel framework to identify subsyndromes (between-person factors) that represent clinically relevant profiles of BPSD and identify symptom clusters (within-person factors) that represent contextually driven daily symptom experiences.

Methods: This study used an intensive longitudinal design in which 68 co-residing family caregivers to persons living with dementia were recruited to proxy report on their care recipient's daily symptom experiences of 23 different BPSD for eight consecutive days (n = 443 diaries).

Objectives: The purpose of this paper is to evaluate the mechanistic process by which family caregivers' situational stress appraisals of behavioral symptoms of dementia (BSD) increase the likelihood of a caregiver engaging in abusive and neglectful behaviors toward their care recipient with dementia. We test the hypotheses that (1) the effect of daily BSD stress appraisals on elder abuse and neglect (EAN) is mediated by the caregivers' emotion dysregulation (2) and the mediation path is moderated by self-compassion.

Methods: This study employed a multitime series design in which participants (N = 453) completed traditional longitudinal surveys at enrollment followed by 21 sequential days of diary surveys (n = 9,513).

Introduction: Identification of molecular biomarkers in the saliva and serum of oral cavity cancer patients represents a first step in the development of essential and efficient clinical tools for early detection and post-treatment monitoring. We hypothesized that molecular analyses of paired saliva and serum samples from an individual would likely yield better results than analyses of either serum or saliva alone.

Materials And Methods: We performed whole-transcriptome and small non-coding RNA sequencing analyses on 32 samples of saliva and serum collected from the same patients with oral squamous cell carcinoma (OSCC) and healthy controls (HC).

The curative treatment of multiple solid tumors, including head and neck squamous cell carcinoma (HNSCC), utilizes radiation. The outcomes for HPV/p16-negative HNSCC are significantly worse than HPV/p16-positive tumors, with increased radiation resistance leading to worse locoregional recurrence (LRR) and ultimately death. This study analyzed the relationship between immune function and outcomes following radiation in HPV/p16-negative tumors to identify mechanisms of radiation resistance and prognostic immune biomarkers.

Article Synopsis
  • Inactivating TP53 mutations disrupt p53 function and can lead to gain-of-function (GOF) activities of mutant p53 proteins, which contribute to tumor growth and spread.
  • The study reveals that GOF mutp53 interacts with components of the minichromosome maintenance complex (MCMs), causing replication stress and chromosomal instability (CIN), which intensifies cancer cell behavior.
  • This interaction triggers a series of signaling pathways, including cGAS-STING-NC-NF-κB, that promote tumor metastasis and create an immunosuppressive tumor environment by dampening interferon responses and enhancing inflammation-related gene expression.

Background: Current personal protective equipment (PPE) practices in UK intensive care units involve "sessional" use of long-sleeved gowns, risking nosocomial infection transmitted via gown sleeves. Data from the first wave of the COVID19 pandemic demonstrated that these changes in infection prevention and control protocols were associated with an increase in healthcare associated bloodstream infections. We therefore explored the use of a protocol using short-sleeved gowns with hand and arm hygiene to reduce this risk.
