A multicenter pilot study of the effectiveness and safety of a monopolar radiofrequency device for improving periorbital and facial fine wrinkles.

Purpose: This study aimed to investigate the effectiveness and safety of a new monopolar radiofrequency device equipped with a 5 cm tip, against fine wrinkles around the eyes and cheeks.

Materials And Methods: This multicentered, prospective pilot study involved treating participants with mild-to-moderate wrinkles on both periorbital areas and cheeks using the monopolar radiofrequency device for one session. One and four months after treatment, wrinkle reduction, overall esthetic improvement, adverse events, and vital signs were evaluated.

Moderation of midlife cognitive activity on tau-related cognitive impairment.

Introduction: We investigated the moderating effects of midlife and late-life cognitive activity (CA) on the relationship between tau pathology and both cognition and cognitive decline.

Methods: Eighty-nine non-demented older adults from a Korean cohort underwent comprehensive evaluations, including CA assessments and tau neuroimaging at baseline, and Mini-Mental State Examination (MMSE) at baseline and the 2-year follow-up.

Results: Greater midlife CA was associated with higher MMSE scores in a given amount of tau pathology, whereas higher levels of midlife CA were associated with faster tau-related decline in MMSE scores, particularly in individuals with mild cognitive impairment.

The Use of Antihypertensive Medication and In Vivo Alzheimer's Disease Pathology.

Objective: We investigated whether the use of antihypertensive medication (AHM) is associated with in vivo Alzheimer's Disease (AD) pathologies in older adults with hypertension and examined if the effect differs by drug-class and blood-brain barrier (BBB) permeability of the drug.

Methods: This cross-sectional study recruited participants from the Korean Brain Aging Study for the Early Diagnosis and Prevention of Alzheimer's Disease. Participants comprised both cognitively normal and impaired older adults diagnosed with hypertension (n = 408).

Liver function and Alzheimer's brain pathologies: A longitudinal study: Liver and Alzheimer's pathologies.

Importance: The neuropathological links underlying the association between changes in liver function and AD have not yet been clearly elucidated.

Objective: We aimed to examine the relationship between liver function markers and longitudinal changes in Alzheimer's disease (AD) core pathologies.

Design: Data from the Korean Brain Aging Study for the Early Diagnosis and Prediction of Alzheimer's Disease, a longitudinal cohort study initiated in 2014, were utilized.

Telomere length, in vivo Alzheimer's disease pathologies and cognitive decline in older adults.

Background: Whether telomere length (TL), an indicator of biological ageing, reflects Alzheimer's disease (AD)-related neuropathological change remains unclear. We investigated the relationships between TL, in vivo AD pathologies, including cerebral beta-amyloid and tau deposition, and cognitive outcomes in older adults.

Methods: A total of 458 older adults were included, encompassing both cognitively normal (CN) individuals and those cognitively impaired (CI), with the CI group consisting of individuals with mild cognitive impairment or AD dementia.

Clinically assessed mycosis fungoides tumor burden index as a prognostic marker in tumor-stage mycosis fungoides: a retrospective cohort study.

Prognostic markers are needed for tumor-stage mycosis fungoides (MF) because of their variable prognosis. The objectives of this study were to explore prognostic markers for tumor-stage MF and assess the prognostic significance of clinically assessed MF tumor burden index (MTBI). MTBI was devised to consider the tumor size ≥ 2 cm, number ≥ 5, ulcers, and body surface area ≥ 50%.

The Moderating Effect of Serum Vitamin D on the Relationship between Beta-amyloid Deposition and Neurodegeneration.

Objective: Previous studies have reported that vitamin D deficiency increased the risk of Alzheimer's disease (AD) dementia in older adults. However, little is known about how vitamin D is involved in the pathophysiology of AD. Thus, this study aimed to examine the association and interaction of serum vitamin D levels with AD pathologies including cerebral beta-amyloid (Aβ) deposition and neurodegeneration in nondemented older adults.

Visual and Auditory Sensory Impairments Differentially Relate with Alzheimer's Pathology.

Objective: We intended to investigate the relationships between visual sensory impairment (VSI) or auditory sensory impairment (ASI) and brain pathological changes associated with cognitive decline in older adults.

Methods: We primarily tried to examine whether each sensory impairment is related to Alzheimer's disease (AD) pathology, specifically beta-amyloid (Aβ) deposition, through both cross-sectional and longitudinal approaches in cognitively unimpaired older adults. Self-report questionnaires on vision and hearing status were administered at the baseline.

A Narrative Review of the Evolution of Diagnostic Techniques and Treatment Strategies for Acral Lentiginous Melanoma.

Acral melanoma (AM) is a subtype of cutaneous melanoma located on the palms, soles, and nails. The pathogenesis of AM involves mechanical stimulation and characteristic tumor-promoting mutations, such as those in the proto-oncogene. Dermoscopy is useful for diagnosing AM, which is characterized by parallel ridge patterns and irregular diffuse pigmentation.

Predictive Performances of ACEF, ACEF II, Updated ACEF II, and EuroSCORE II Risk Scores in Patients Undergoing Isolated Off-pump Coronary Artery Bypass Grafting.

Objectives: This study evaluated the performances of the age, creatinine, and ejection fraction (ACEF) I and II scores and compare them with that of the European System for Cardiac Operative Risk Evaluation (EuroSCORE) II score in patients who underwent isolated off-pump coronary artery bypass grafting (OPCABG). Additionally, this study was designed to externally validate the performance of the updated ACEF II score.

Design: Retrospective observational study.

Microbiome-derived indole-3-lactic acid reduces amyloidopathy through aryl-hydrocarbon receptor activation.

Alzheimer's disease (AD) pathogenesis has been associated with the gut microbiome and its metabolites, though the specific mechanisms have remained unclear. In our study, we used a multi-omics approach to identify specific microbial strains and metabolites that could potentially mitigate amyloidopathy in 5xFAD mice, a widely used model for AD research. Among the microbial strains tested, three showed promising results in reducing soluble amyloid-beta (Aβ) levels.

Moderation of thyroid hormones for the relationship between amyloid and tau pathology.

Background: Altered thyroid hormone levels have been associated with increased risk of Alzheimer's disease (AD) dementia and related cognitive decline. However, the neuropathological substrates underlying the link between thyroid hormones and AD dementia are not yet fully understood. We first investigated the association between serum thyroid hormone levels and in vivo AD pathologies including both beta-amyloid (Aβ) and tau deposition measured by positron emission tomography (PET).

Impact of pericardial calcification on early postoperative outcomes after pericardiectomy: a retrospective observational study.

Background: Owing to the lack of understanding of the clinical significance of pericardial calcification during pericardiectomy, whether pericardial calcification should be considered when determining the optimal timing for pericardiectomy is debatable. We aimed to investigate the effect of pericardial calcification on early postoperative outcomes in patients who underwent pericardiectomy for constrictive pericarditis.

Methods: Altogether, 44 patients who underwent pericardiectomy for constrictive pericarditis were enrolled.

Comparative analysis of del Nido cardioplegia versus blood cardioplegia in isolate coronary artery bypass grafting.

Background: This study examined the efficacy of del Nido cardioplegia compared with traditional blood cardioplegia in adult cardiac surgery for isolated coronary artery bypass grafting by evaluating the early postoperative outcomes.

Methods: A total of 119 patients who underwent isolated conventional coronary artery bypass grafting were enrolled and divided into two groups (del Nido cardioplegia group [n = 36] and blood cardioplegia group [n = 50]) based on the type of cardioplegia used. This study compared the preoperative characteristics, intraoperative data, and early postoperative outcomes.
