Chronic obstructive pulmonary disease (COPD) is a progressive lung disease commonly associated with multiple comorbidities, significantly affecting prognosis and clinical management. Systemic inflammation and shared risk factors contribute to the development of these comorbidities. Additionally, Preserved Ratio Impaired Spirometry (PRISm) has been recognized as a high-risk condition for COPD progression; however, its comorbid burden remains insufficiently studied.

Background: Amyloid beta (Aβ) plaque burden, as measured by positron emission tomography (PET), is increasingly being used as a biomarker for Alzheimer's disease (AD) as well as a screening or monitoring tool for clinical trials with amyloid-lowering drugs. However, PET imaging is expensive, invasive and not widely available for all patients, necessitating alternative means to assess brain Aβ accumulation.
Objectives: In this study, we measured levels of Aβ42, Aβ40 and Aβ38 in saliva samples from cognitively unimpaired older adults (n=93; 61.
Study Objectives: Memory consolidation during non-rapid eye movement slow wave sleep (NREM SWS) involves reactivation of a hippocampal index which integrates distributed cortical representations of an experience. This study examined whether individual differences in brain network properties that align with this theoretical organization were associated with interindividual variability in memory consolidation during sleep.
Methods: Thirty-six older adults (μage=72.
Approximately half of the patients with sepsis require intensive care unit (ICU) management and their mortality rate remains high. The concept of withholding and withdrawal life-sustaining treatment (WWLST) issue was introduced to limit the suffering of critically ill patients. However, little is known about the characteristics and outcomes of WWLST in patients with sepsis.

Case Description: A 73-year-old East Asian woman was diagnosed with stage IV anaplastic lymphoma kinase (ALK)-rearranged lung adenocarcinoma in the right middle lobe (RML).
Objective: Healthcare professionals must possess statistical literacy to provide evidence-based care and engage patients in decision-making. However, there have been concerns about healthcare professionals' inadequate understanding of health statistics. As an initial step in addressing the issue, we assessed the statistical literacy of medical students and doctors in South Korea by evaluating their comprehension of four statistical concepts: (a) single-event probability, (b) relative risk reduction, (c) positive predictive value and (d) 5-year survival rate.

However, it is unclear whether Aβ contributes to subtle memory deficits observed during the preclinical stage. The heterogeneous emergence of Aβ deposition may selectively impact certain memory domains, which rely on distinct underlying neural circuits.

Case Presentation: We report the case of a 56-year-old East Asian male with a 27-year history of BD, who had no respiratory symptoms, such as hemoptysis, cough, or fever.

Background: Medical students and professionals often struggle to understand medical test results, which can lead to poor medical decisions. Natural frequency tree-based training (NF-TT) has been suggested to help people correctly estimate the predictive value of medical tests. We aimed to compare the effectiveness of NF-TT with conventional conditional probability formula-based training (CP-FT) and investigate student variables that may influence NF-TT's effectiveness.

We measured levels of Aβ38/40/42 in plasma samples from cognitively-unimpaired older adults and determined the relationships between Aβ levels and amyloid positron-emission-tomography (PET) and performance on a learning and memory task. We found that all Aβ peptides individually and the Aβ42/40 ratio, but not the Aβ42/38 ratio, were significantly correlated with brain amyloid (Aβ-PET).

Backgruound: Poorly differentiated thyroid carcinoma (PDTC) accounts for a small portion of thyroid carcinomas but contributes to a significant proportion of thyroid carcinoma-associated deaths. The clinicopathological prognostic factors and clinical outcomes of PDTC remain unclear. We aimed to evaluate the clinical outcomes of patients with PDTC after curative treatment.

Tramadol, a weak μ-opioid receptor agonist, has been used worldwide for pain management. It is considered to have a favorable safety profile without serious adverse events; however, safety issues of respiratory depression were proposed by regulatory governments. We aimed to examine the risk and contributing factors associated with tramadol-related respiratory depression using a real-world database, VigiBase.

The consequences of coronavirus disease 2019 (COVID-19) are particularly severe in older adults with a disproportionate number of severe and fatal outcomes. Therefore, this integrative review aimed to provide a comprehensive overview of the clinical characteristics, management approaches, and prognosis of older patients diagnosed with COVID-19. Common clinical presentations in older patients include fever, cough, and dyspnea.

Although the advent of immune checkpoint inhibitors (ICIs) has revolutionized cancer treatment, their efficacy and safety in patients with concurrent autoimmune diseases (AD) and malignancies remains uncertain. Several studies have suggested the safe administration of ICIs in patients with AD, indicating that successful cancer therapy can alleviate CAD symptoms.

However, 5-y survival rates and incidence, without mortality, have been frequently communicated to the public. Based on the literature that people's perceptions and judgments can be altered by the way of presenting health statistics, the current study examined whether mortality alongside 5-y survival and incidence would influence laypeople's perceptions of the effectiveness of cancer screening and screening intention.

For memories containing emotional content, hippocampal-amygdala dynamics facilitate consolidation over a sleep bout. This study tested if modularity and centrality-graph theoretical measures that index the level of segregation/integration in a system and the relative import of its nodes-map onto central tenets of memory consolidation theory and sleep-related processing.
View Article and Find Full Text PDFAlzheimer's disease (AD) is the most common type of dementia, characterized by early memory impairments and gradual worsening of daily functions. AD-related pathology, such as amyloid-beta (Aβ) plaques, begins to accumulate many years before the onset of clinical symptoms. Predicting risk for AD via related pathology is critical as the preclinical stage could serve as a therapeutic time window, allowing for early management of the disease and reducing health and economic costs.

However, the tensor model is necessarily limited by its assumptions. Neurite Orientation Dispersion and Density Imaging (NODDI) can offer insights into microstructural features of WM change.
