A single-cell transcriptomic atlas of developing inhibitory neurons reveals expanding and contracting modes of diversification.

The cerebral cortex relies on vastly different types of inhibitory neurons to compute. How this diversity emerges during development remains an open question. The rarity of individual inhibitory neuron types often leads to their underrepresentation in single-cell RNA sequencing (scRNAseq) datasets, limiting insights into their developmental trajectories.

Unraveling the subjective well-being of formal and informal caregivers for people with dementia: a comparative analysis.

Background: Both formal and informal caregivers play pivotal roles in long-term dementia care, demonstrating a shared dedication to providing comprehensive care and support for individuals with dementia. These two caregiver groups exhibit both similarities and differences in their caregiving experiences, contributing to variations in subjective well-being outcomes. However, limited research has compared the psychological well-being and self-rated health of these two caregiver groups, or explored the influencing factors.

Oedema index trajectories at heart failure nurse clinics over 6 months after acute heart failure predict patient outcomes: a retrospective cohort study.

After acute HF, HF nurses provide home care suggestions based on oedema status assessed at outpatient clinics. However, the pattern of serial oedema changes and their associations with patient outcomes are unknown.

Interventions to enhance the core competencies of clinical nursing preceptors: a protocol for a systematic review.

Introduction: Clinical nursing preceptors (CNPs) teach nursing skills to students in real medical scenarios and develop their professionalism. The adequacy of CNPs' teaching competencies affects the effectiveness of student learning, so it is crucial to seek the best evidence for teaching competency interventions. This report describes a protocol for a systematic review to identify and analyse interventions to enhance the teaching competencies of CNPs.

Clinical characteristics and influencing factors of serious fall injuries among older inpatients: A secondary analysis of multicenter cross-sectional administrative data.

Background: Inpatient falls are common adverse events in hospitals, particularly among older adults. However, current research on falls in the older population is limited by small sample sizes and reliance on single-center designs without distinguishing the different levels of fall injuries.

Objective: To examine the circumstances of falls in older inpatients and investigate the factors influencing serious fall injuries.

Higher patient activation is associated with lower odds of functional limitation in older adults with chronic diseases.

Objectives: To investigate the association between patient activation and functional limitation among older adults living with multiple chronic conditions.

Methods: We performed a secondary analysis of a parent study, which examined the relationship between self-efficacy and both inflammatory biomarkers and frailty. We conducted multivariate logistic regression while controlling for the patients' sociodemographic variables and comorbidities to examine the association between self-reported functional limitation and patient activation as measured by the Patient Activation Measure (PAM-10).

Prognostic Significance of Phenylalanine in Heart Failure: Clinical Insights and Inter-Organ Crosstalk Snapshot.

Heart failure (HF) remains a leading cause of morbidity and mortality globally, necessitating the identification of reliable prognostic biomarkers to guide therapeutic interventions. Recent clinical observations have underscored phenylalanine (PHE) as a prognostic marker in HF, although the mechanisms involving inter-organ crosstalk remain understood. This study adopted a dull approach, with a retrospective analysis of 550 HF patients to establish the prognostic value of pre-discharge PHE levels and a study on the inter-organ crosstalk of PHE among 24 patients.

Efficient Dlx2-mediated astrocyte-to-neuron conversion and inhibition of neuroinflammation by NeuroD1.

In vivo astrocyte-to-neuron (AtN) conversion induced by overexpression of neural transcriptional factors has great potential for neural regeneration and repair. Here, we demonstrate that a single neural transcriptional factor, Dlx2, converts mouse striatal astrocytes into neurons in a dose-dependent manner. Lineage-tracing studies in Aldh1l1-CreERT2 mice confirm that Dlx2 can convert striatal astrocytes into DARPP32 and Ctip2 medium spiny neurons (MSNs).

Sustained frailty remission and dementia risk in older adults: A longitudinal study.

Introduction: Physical frailty is reversible, but little is known about the sustainability of frailty remission and its impact on dementia.

Methods: Data were derived from the National Health and Aging Trends Study (NHATS) (2011 to 2021). Physical frailty was assessed using the Fried frailty phenotype, and frailty transition patterns across three waves were defined.

Fabrication of a Near-Infrared-Emissive Probe for Detecting Dipeptidyl Peptidase 4 in the Liver of Diabetic Mice and Clinical Serum.

Dipeptidyl peptidase 4 (DPP4) plays a key role in glucose metabolism, which has been a close target for diabetes pathology and treatment. It is significant for the evaluation of cellular DPP4 activity in various biological systems. Fluorescence imaging technology is currently a popular method for detecting enzymes in living cells due to its advantages of high selectivity, high sensitivity, high spatiotemporal resolution, and real-time visualization.

Real-time tracking of electron transfer at catalytically active interfaces in lithium-ion batteries.

Transition metals and related compounds are known to exhibit high catalytic activities in various electrochemical reactions thanks to their intriguing electronic structures. What is lesser known is their unique role in storing and transferring electrons in battery electrodes which undergo additional solid-state conversion reactions and exhibit substantially large extra capacities. Here, a full dynamic picture depicting the generation and evolution of electrochemical interfaces in the presence of metallic nanoparticles is revealed in a model CoCO/Li battery via an in situ magnetometry technique.

The purpose of the current meta-analysis was to examine the effects of vitamins and PUFAs on cognition and to compare the effects of single and multiple nutrient subgroups in patients with MCI.

Methods: Randomized controlled trials (RCTs) written in English and Chinese were retrieved from eight databases, namely, PubMed, CENTRAL, Embase, CINAHL, Web of Science, SinoMed, CNKI, and Wanfang Data, from their respective dates of inception until 16 July 2023.

A single mitochondria-targetable fluorescent probe for visualizing cysteine and glutathione in ferroptosis of myocardial ischemia/reperfusion injury.

Ferroptosis plays an important role in the early stage of myocardial ischemia/reperfusion (MI/R) injury, which is closely associated with the antioxidant damage of mitochondrial cysteine (Cys)/glutathione (GSH)/glutathione peroxidase 4 (GPX4) axis. Visualization of Cys and GSH in mitochondria is meaningful to value ferroptosis and further contributes to understanding and preventing MI/R injury. Herein a mitochondria-targetable thiols fluorescent probe (MTTP) was designed and synthesized based on sulfonyl benzoxadiazole (SBD) chromophore with a triphenylphosphine unit as the mitochondria-targeted functional group.
