Dementia Care Research and Psychosocial Factors.

Background: Older adults with cognitive impairments will benefit from multicomponent interventions include cognitive training, exercise, and lifestyle modifications. Many digital therapeutic products predominantly focus on computerized cognitive training, lacking effective approaches to other crucial interventions. This study aimed to investigate the long term effects of multidimensional comprehensive cognitive intervention training program - Brain and Body Rehab Training (BBRT), which integrates multidomain cognitive training with physical-cognitive training and multidimensional lifestyle interventions on cognitive performance in participants with cognitive impairment after a 8-month follow-up.

Lingo1 in the hippocampus contributes to cognitive dysfunction after anesthesia and surgery in aged mice.

Cognitive impairment caused by anesthesia and surgery is one of the most common complications with multiple etiologies that occurs in elderly patients. The underlying mechanisms are not fully understood, and there is a lack of therapeutic strategies. Increasing evidence has demonstrated that myelin loss, abnormal phosphorylation of the tau protein and neuronal apoptosis are substantial driving factors of cognitive deficits.

Antihypertensive strategies for the prevention of secondary stroke: a systematic review and meta-analysis.

Background: Stroke is an important contributor to disability and death globally. Hypertension is a main risk factor for recurrent stroke in patients with ischemic and hemorrhagic stroke or transient ischemic attack. Higher systolic blood pressure, diastolic blood pressure, pulse pressure and mean arterial pressure at admission are independently associated with the risk of stroke recurrence.

Near-infrared spectroscopy combined with vascular occlusion test to predict acute kidney injury in patients undergoing cardiac surgery: a prospective observational study.

Background: Near-infrared spectroscopy (NIRS) enables a non-invasive measurement of tissue oxygen saturation (StO) in regions illuminated by near-infrared lights. Vascular occlusion test (VOT) serves as a model to artificially induce forearm ischemia-reperfusion. The combination of StO monitoring and VOT allows for dynamic evaluation of the balance between oxygen delivery and consumption in tissue, as well as the functional reserve of microcirculation.

Low L3 skeletal muscle index and endometrial cancer: a statistic pooling analysis.

Objective: Sarcopenia, a condition characterized by the gradual decline of muscle mass, strength, and function, is a key indicator of malnutrition in cancer patients and has been linked to poor prognoses in oncology. Sarcopenia is commonly assessed by measuring the skeletal muscle index (SMI) of the third lumbar spine (L3) using computed tomography (CT). This meta-analysis aimed to explore the relationship between low SMI and clinicopathological features, as well as prognosis, in individuals with endometrial cancer (EC).

The gut-brain axis underlying hepatic encephalopathy in liver cirrhosis.

Up to 50-70% of patients with liver cirrhosis develop hepatic encephalopathy (HE), which is closely related to gut microbiota dysbiosis, with an unclear mechanism. Here, by constructing gut-brain modules to assess bacterial neurotoxins from metagenomic datasets, we found that phenylalanine decarboxylase (PDC) genes, mainly from Ruminococcus gnavus, increased approximately tenfold in patients with cirrhosis and higher in patients with HE. Cirrhotic, not healthy, mice colonized with R.

Untargeted Metabolomics Reveals Metabolic Link Between Histone H3K27 Demethylase UTX and Neurodevelopment.

Ubiquitously transcribed tetratricopeptide repeat on chromosome X (UTX) is a chromatin modifier responsible for regulating the demethylation of histone H3 lysine 27 trimethylation (H3K27me3), which is crucial for human neurodevelopment. To date, the impact of UTX on neurodevelopment remains elusive. Therefore, this study aimed to investigate the potential molecular mechanisms underlying the effects of UTX on neurodevelopment through untargeted metabolomics based on ultra-high-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS).

Genetic and clinical analysis of in amyotrophic lateral sclerosis.

Background: Considerable heterogeneity in genotypes and phenotypes has been observed among patients with amyotrophic lateral sclerosis (ALS) harbouring optineurin gene () mutations, as reported in prior studies. The study aimed to elucidate the correlation between genotypes and phenotypes.

Methods: gene variants were screened within a substantial Chinese cohort of patients with ALS, encompassing LoF and rare missense variants.

Ras S89D mutation induced allosteric changes that promoted its nucleotide exchange and signaling activation.

The small GTPase Ras is among the most frequently mutated genes and its mutations often drive oncogenesis across various cancers. While the role of NRas phosphorylation at S89 in the context of a Q61R mutation in melanoma genesis remains controversial, the impact of S89 phosphorylation on NRas function has not been fully elucidated. In this study, we employed the S89D phosphorylation-mimetic mutation and demonstrated that the S89D mutation alone activated all Ras isoforms by increasing the GTP-bound population, thereby promoting ERK phosphorylation and cell proliferation.

Proteomic Analysis of Plasma Exosomes Enables the Identification of Lung Cancer in Patients With Chronic Obstructive Pulmonary Disease.

Chronic obstructive pulmonary disease (COPD) is confirmed as an independent risk factor for the development of lung cancer. Although low-dose CT screening significantly reduces the mortality rate of lung cancer, the misdiagnosis and missed diagnosis rates remain high in the COPD population. Additionally, several COPD patients are unable to undergo invasive histological examinations.

Pear-Shaped Disc as a Risk Factor for Postoperative Sclerotic Modic Changes After Transforaminal Lumbar Interbody Fusion.

Objective: Pear-shaped disc could increase the risk of intraoperative end-plate injury, which may lead to postoperative sclerotic Modic Changes (MCs). However, there are no studies on the relationship between pear-shaped disc and postoperative sclerotic MCs. Therefore, this study investigates the risk factors for postoperative sclerotic MCs following transforaminal lumbar interbody fusion (TLIF).

Metformin-based nanomedicines for reprogramming tumor immune microenvironment.

Immunotherapy has transformed current cancer management, and it has achieved significant progress over last decades. However, an immunosuppressive tumor microenvironment (TME) diminishes the effectiveness of immunotherapy by suppressing the activity of immune cells and facilitating tumor immune-evasion. Adenosine monophosphate-activated protein kinase (AMPK), a key modulator of cellular energy metabolism and homeostasis, has gained growing attention in anti-tumor immunity.

Recent advances in the role of atypical cadherin FAT1 in tumorigenesis (Review).

The FAT atypical cadherin 1 (FAT1) gene is the ortholog of the fat gene and encodes the protocadherin FAT1. FAT1 belongs to the cadherin superfamily, a group of full-length membrane proteins that contain cadherin-like repeats. In various types of human cancer, FAT1 is one of the most commonly mutated genes, and is considered to be an emerging cancer biomarker and a potential target for novel therapies.
