Summary: Neurodegenerative diseases have become a major concern in an aging society, with the inflammasome, particularly the NLRP3 inflammasome, playing a crucial role in their pathogenesis. Understanding the activation mechanisms of the NLRP3 inflammasome and its key role in neurodegenerative disorders provides a theoretical basis for the discovery of new prevention and treatment methods. Various treatment strategies targeting the NLRP3 inflammasome pathway have been reviewed to alleviate neuroinflammation in neurodegenerative disorders.

Summary: This study developed a reliable Parkinson's disease (PD) model in zebrafish, which can simulate the related symptoms and pathophysiology of PD and help in drug development. Chronic exposure to manganese chloride (MnCl2) can lead to motor and non-motor PD-like symptoms in adult zebrafish, including motor dysfunction, anxiety and depression-like behavior, and olfactory dysfunction. These symptoms are associated with decreased dopamine, activation of oxidative stress-mediated apoptotic pathway, decreased brain derived neurotropic factor (BDNF), and increased pro-inflammatory cytokines levels.

Summary: This study aims to provide a comprehensive overview of the involvement of the kynurenine pathway (KP) in the pathophysiology of Alzheimer's disease (AD) and Parkinson's disease (PD) and discuss potential therapeutic opportunities. The results showed altered levels of KP metabolites in the brains of AD and PD patients, and associations between peripheral levels of KP metabolites and cognitive function in these patients.

Summary: Parkinson's disease is associated with neuroinflammation, which is crucial in its development and progression. Microglia activation and overexpression of the M1 phenotype play a central role in driving neuroinflammation and affecting mitochondria. The NLRP3-Nrf2 axis regulates mitochondrial function and processes such as oxidative stress, mitochondrial respiratory function, and dynamics. Targeting this axis may contribute to preserving mitochondrial integrity and extend the lifespan of Parkinson's patients by preventing neuroinflammatory damage to mitochondria.

Summary: This study used a rodent model to investigate the striatal outflow circuitry responsible for L-DOPA-induced dyskinesias (LIDs) in Parkinson's disease (PD). The activation of the indirect pathway was found to effectively suppress LIDs, highlighting the importance of maintaining an equilibrium in the activity of both striatal pathways for normal movement. These findings provide insights into the intrinsic mechanisms and potential therapeutic targets for suppressing LIDs in PD patients.

Summary: According to this study, Parkinson's disease patients can be categorized into brain-predominant PD and PD with body involvement phenotypes based on the onset of cardiac sympathetic denervation (CSD). The study found that PD patients with body involvement had more severe initial symptoms and experienced faster progression of motor deterioration, indicating potentially more severe involvement of the central and peripheral nervous systems.

Summary: Recent studies have shown that hydrogen sulfide (H2S) has a neuroprotective effect in neurodegenerative diseases, possibly mediated by brain-derived neurotrophic factor (BDNF). This study aimed to investigate the effects of H2S on neural damage in Parkinson's disease (PD) and the role of the BDNF-TrkB pathway. A PD model was created using 1-methyl-phenyl-1,2,3,6-tetrahydropyridine (MPTP). It was found that H2S treatment reduced motor deficits in the PD model and the BDNF-TrkB pathway played a role in this protective effect.

Summary: Parkinson's disease is the second most common neurodegenerative disease and is associated with iron accumulation and iron-dependent phospholipid peroxidation, which leads to a novel cell death pathway called ferroptosis. Recent research has focused on targeting ferroptosis as a potential intervention for PD.

Summary: Based on the theory of coordinated reset (CR) stimulation, the noninvasive coordinated multifocal burst stimulation (COMBS) was developed to modulate the target frequency in the primary motor cortex. The results showed an increase in a-band power and low I3-band power during the finger-tapping task, and a reduction in low I3-band event-related desynchronization after COMBS. However, there were no significant changes in cortical excitability measured by various parameters.

Summary: This study evaluated the "lessebo effect" in disease modification trials in Parkinson's disease and found that it did not exist in these trials. However, the use of placebo instead of an active comparator was a limitation. Prospective measurement of expectation of benefit could help assess the various impacts of placebo use.

Summary: This study explores the perspectives of internal medicine inpatients on the collection and use of sociodemographic and social needs information. Patients recognize the importance of collecting this data to address their needs, but acknowledge the challenges faced by hospital teams in providing ideal care. Trust and transparency in the patient-provider relationship are seen as crucial to alleviate concerns about bias, discrimination, and confidentiality.

Summary: This study aims to understand the perspectives of people living with HIV (PLWH) and their health care providers on the feasibility of integrating vocational rehabilitation with health care services. The study found that health care providers have little experience in assisting patients with employment, and PLWH have little experience in receiving employment interventions from their health care team. Therefore, further study is needed on the implementation processes and goals of these interventions.

Summary: In this study, the mechanisms of transcranial ultrasound stimulation (TUS) in human primary motor cortex were investigated by administering different drugs to healthy subjects. The results showed that all study drugs reduced the plasticity effects of tbTUS on motor cortex excitability. The conclusion is that tbTUS may induce NMDA-dependent synaptic plasticity and is influenced by increased GABAA receptor activity and blockers of voltage-gated Na+ and Ca2+ channels.

Summary: Several Canadian provinces and territories have reformed their health systems by centralizing power, resources, and responsibilities. A study was conducted to explore motivating factors and perceived impacts of centralization reforms on public health systems and essential operations. The findings showed that the centralization reforms had both positive and negative effects on public health, including improved efficiency and quality in some aspects, but also an undermining of essential functions and workforce precarity.

Summary: The study found that three bans on eviction enforcement in Ontario, Canada had an impact on eviction filings, with a significant decrease in average weekly applications for non-payment of rent and other reasons, but none of them eliminated eviction filings completely. The first ban had a substantial effect, but subsequent bans were less effective. Therefore, implementing upstream policies that address the root causes of displacement would be more effective in future public health emergencies.

Summary: Among 122 genetically confirmed NBIA patients, KRS had the best survival and longest preservation of ambulation ability, while classical PKAN and MPAN patients showed similar progression patterns in loss of ambulation ability, with MPAN patients having a slower progression to death. Spasticity was identified as the most significant factor associated with death.
