Pilot of a multicomponent program for people with dementia and their care partners: Health services staff expectations, experiences and observations.

There is increased recognition of the need to improve post-diagnostic pathways for people with dementia and their care partners living in the community to access rehabilitation services to support independence and wellbeing. However, there is minimal evidence on implementing rehabilitation services for this population. The study aimed to present the expectations and experiences of allied health staff involved in piloting the Sustainable Personalised Interventions for Cognition, Care and Engagement (SPICE) program based at an outpatient clinic of a public rehabilitation hospital.

Multitargeting Pt(IV) Derivatives of Cisplatin or Oxaliplatin Inhibit Tumor Growth in Mice without Inducing Neuropathic Pain.

Cisplatin and oxaliplatin are Pt(II) anticancer agents that are used to treat several cancers, usually in combination with other drugs. Their efficacy is diminished by dose-limiting peripheral neuropathy (PN) that affects ∼70% of patients. PN is caused by selective accumulation of the platinum drugs in the dorsal root ganglia (DRG), which overexpress transporters for cisplatin and oxaliplatin.

Differential impact of lymphatic outflow pathways on cerebrospinal fluid homeostasis.

Dysfunctional lymphatic drainage from the central nervous system (CNS) has been linked to neuroinflammatory and neurodegenerative disorders, but our understanding of the lymphatic contribution to CNS fluid autoregulation remains limited. Here, we studied forces that drive the outflow of the cerebrospinal fluid (CSF) into the deep and superficial cervical lymph nodes (dcLN and scLN) and tested how the blockade of lymphatic networks affects CNS fluid homeostasis. Outflow to the dcLN occurred spontaneously in the absence of lymphatic pumping and was coupled to intracranial pressure (ICP), whereas scLN drainage was driven by pumping.

Ultra-fast single-crystal CVD diamonds in the particle time-of-flight (PTOF) detector for low yield burn-history measurements on the NIF (invited).

The Particle Time of Flight (PTOF) diagnostic is a chemical vapor deposition diamond-based detector and is the only diagnostic for measuring nuclear bang times of low yield (<1013) shots on the National Ignition Facility. Recently, a comprehensive study of detector impulse responses revealed certain detectors with very fast and consistent impulse responses with a rise time of <50 ps, enabling low yield burn history measurements. At the current standoff of 50 cm, this measurement is possible with fast 14 MeV neutrons from deuterium-tritium (DT) fusion plasmas.

Association of Phosphate Supplements With Refeeding Oedema in Restrictive Eating Disorders.

Objective: Refeeding oedema, believed to result from the effects of insulin on renal sodium retention and subsequent oedema formation, typically occurs during the first 2 weeks after reintroduction of nutrition in individuals with severe malnutrition and can intensify body image distress in patients with eating disorders (EDs). Phosphate supplements have been found to increase insulin sensitivity, and it is hypothesised that they may also contribute to refeeding oedema in patients with EDs.

Method: In this retrospective cohort study of 633 patients with severe malnutrition due to anorexia nervosa (AN) or avoidant restrictive food intake disorder (ARFID), the impact of phosphate supplementation on the rate of weight gain was investigated.

ChatGPT as a patient education tool in colorectal cancer-An in-depth assessment of efficacy, quality and readability.

Aim: Artificial intelligence (AI) chatbots such as Chat Generative Pretrained Transformer-4 (ChatGPT-4) have made significant strides in generating human-like responses. Trained on an extensive corpus of medical literature, ChatGPT-4 has the potential to augment patient education materials. These chatbots may be beneficial to populations considering a diagnosis of colorectal cancer (CRC).

Volumetric Artificial Intelligence Analysis of Prerupture and Postrupture Cerebral Aneurysms: Assessment of Morphologic Change.

Background: Cerebral aneurysm rupture is a major cause of potential years of life lost. Research on rupture risk has often compared unruptured and ruptured aneurysms, with the implicit assumption that the rupture event does not significantly change aneurysm morphology. However, aneurysm morphology is charged by rupture, although precisely how remains a matter of debate.

Racial and Ethnic Disparities in the Use and Outcomes With WATCHMAN FLX: A SURPASS Analysis of the NCDR Left Atrial Appendage Occlusion Registry.

Background: Left atrial appendage occlusion (LAAO) is increasingly used as an alternative to oral anticoagulation for stroke prevention in select patients with atrial fibrillation. Data on outcomes in racial and ethnic minority individuals are limited. This analysis assessed differences in the use and outcomes of LAAO by race and ethnicity in a large national registry.

Effects of Manipulated Rainfall and Intraspecific Variation Within Dominant Species on Community Assembly: Insights From a Long-Term Grassland Restoration Experiment.

Grasslands converted to agricultural land use can be reestablished by sowing seeds of native species and temporal dynamics of diversity under altered climate can inform community assembly in the context of global change. We quantified three aspects of diversity (species richness, phylogenetic diversity, and functional diversity) in restored prairie plots sown with different ecotypes of two dominant grass species and manipulated rainfall to understand the relative importance of abiotic filtering and population source of dominant species on community assembly. We also evaluated the contributions of intra- and interspecific variations in functional traits across plots sown with different ecotypes of dominant species.

Loss of Bone Density in Patients with Anorexia Nervosa Food That Alone Will Not Cure.

Background: Anorexia Nervosa is a highly lethal illness that is also associated with many medical complications. Food restriction and weight loss define this illness. Most of its physical complications are reversible with weight restoration, with the notable exception of the loss of bone density, which is commonly present in anorexia nervosa.

Health Care Workers' Trust in Leadership: Why It Matters and How Leaders Can Build It.

Background: Rebuilding patient trust in the US health care system has received considerable attention recently, but there has been little focus on health care workers' (HCWs) trust in the leaders of health care delivery organizations. This study explores (1) the professional impact on HCWs of trusting the leaders of the organizations where they work and (2) the leadership actions that build HCWs' trust.

Methods: The authors examined these questions using a survey that was crowdsourced to 353 HCWs through social media posts and e-mails from national health organizations.

Dopamine release plateau and outcome signals in dorsal striatum contrast with classic reinforcement learning formulations.

We recorded dopamine release signals in centromedial and centrolateral sectors of the striatum as mice learned consecutive versions of visual cue-outcome conditioning tasks. Dopamine release responses differed for the centromedial and centrolateral sites. In neither sector could these be accounted for by classic reinforcement learning alone as classically applied to the activity of nigral dopamine-containing neurons.

'Flashforward' mental imagery in adolescents: exploring developmental differences and associations with mental health.

Background: Future events can spring to mind unbidden in the form of involuntary mental images also known as 'flashforwards', which are deemed important for understanding and treating emotional distress. However, there has been little exploration of this form of imagery in youth, and even less so in those with high psychopathology vulnerabilities (e.g.

Accurately estimating correlations between demographic parameters: A comment on Deane et al. (2023).

Estimating correlations among demographic parameters is an important method in population ecology. A recent paper by Deane et al. ( 13:e9847, 2023) attempted to explore the effects of different priors for covariance matrices on inference when using mark-recovery data.

Anti-inflammatory effects of phytocannabinoids and terpenes on inflamed Tregs and Th17 cells in vitro.

Aims: Phytocannabinoids and terpenes from Cannabis sativa have demonstrated limited anti-inflammatory and analgesic effects in several inflammatory conditions. In the current study, we test the hypothesis that phytocannabinoids exert immunomodulatory effects in vitro by decreasing inflammatory cytokine expression and activation.

Key Methods: CD3/CD28 and lipopolysaccharide activated peripheral blood mononuclear cells (PBMCs) from healthy donors (n = 6) were treated with phytocannabinoid compounds and terpenes in vitro.

Anticoagulation Alone vs Anticoagulation Plus Aspirin or DAPT Following Left Atrial Appendage Occlusion.

Background: The prevalence of and outcomes associated with different antithrombotic strategies after left atrial appendage occlusion (LAAO) are not well described.

Objectives: This study sought to evaluate patterns of antithrombotic medication strategies at discharge following LAAO with the Watchman FLX device in real-world practice and to compare the risk of adverse events among the different antithrombotic regimens.

Methods: The authors evaluated patients in the NCDR (National Cardiovascular Data Registry) LAAO Registry who underwent LAAO with the second-generation LAA closure device between 2020 and 2022.

Modelling Adverse Events in Patients Receiving Chronic Oral Corticosteroids in the UK.

Background: Oral corticosteroids (OCS) are effective anti-inflammatory agents used across a range of conditions. However, substantial evidence associates their use with increased risks for adverse events (AEs), causing high burden on healthcare resources. Emerging biologics present as alternative agents, enabling the reduction of OCS use.

Specificity of Episodic Future Thinking in Adolescents: Comparing Childhood Maltreatment, Autism Spectrum, and Typical Development.
