Solitary large hepatocellular carcinomas (SLHCC) form a heterogeneous group of patients with different survival probabilities. The aim of our study was to develop a simple prognostic index for identifying prognostic subgroups of SLHCC patients.A retrospective analysis of clinical data from 268 patients with operable SLHCC was conducted to investigate prognostic factors and to construct a score system based on risk factors. A Cox proportional hazard regression analysis was used to evaluate the variables associated with prognosis. Survival analyses were performed using Kaplan-Meier survival curves.Three variables remained in the final multivariate model: platelet to lymphocyte ratio (PLR), microvascular invasion (MVI), and tumor size with hazard ratios equal to 1.004 (95% confidence interval: 1.001-1.006), 1.092 (1.044-1.142), and 2.233 (1.125-2.233), respectively. A score of 1 was assigned to each risk factor. Patient scores were determined based on these risk factors; thus, the scores ranged between 0 and 3. Ultimately, three categories (0, 1-2, 3) were defined. Patients with scores of 3 had a 5-year survival rate of 25.4%, whereas patients with a score of 0 had a 5-year survival rate of 52.1%. The prognosis significantly worsened as the score increased. Similar results were found among cirrhotic and noncirrhotic patients.Our simple prognostic index successfully predicts SLHCC survival.

Background: Disease progression within 24 months (POD24) significantly impacts overall survival (OS) in patients with follicular lymphoma (FL). This study aimed to develop a robust predictive model, FLIPI-C, using a machine learning approach to identify FL patients at high risk of POD24.
Methods: A cohort of 1,938 FL patients (FL1-3a) from seventeen centers nationwide in China was randomly divided into training and internal validation sets (2:1 ratio).

Background & Aims: Skeletal muscle (SM) health has significant prognostic value in geriatric and chronic disease populations, yet its assessment is frequently omitted due to challenges in evaluation. The creatinine-to-cystatin C ratio (CCR) is a simple serum-based measure that associates well with measured SM quantity (myopenia) and strength, but evidence for its association with SM quality (myosteatosis) is limited and conflicting. This study investigated the association between CCR and computed tomography (CT) measures of myopenia and myosteatosis.

Frailty is one of the most concerning aspects of global population aging, and early identification is crucial to prevent or reverse its progression. Simple, universal, and efficient frailty assessment technologies are essential for the timely detection of frailty in older patients. Various multi-dimensional assessment instruments have been developed to quantify frailty phenotypes; we review the literature on wearable sensor technologies leveraged for older person frailty assessment.

The serum uric acid-to-creatinine ratio (UCR) may be a simple method for assessing xanthine oxidase overactivation, which may contribute to an increase in serum uric acid production and oxidative stress. In this study, we investigated the nonlinear association between the UCR and long-term mortality in patients with hypertension. Data were acquired from the National Health and Nutrition Examination Survey database, and a total of 11,346 patients with hypertension were included.
