Nuciferine (NF) is the main active ingredient of lotus leaf, which has anti-inflammatory, anti-tumour and other effects. The purpose of this work was to explore the target and mechanism of NF in preventing cancer cachexia-induced muscle atrophy.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The action of NF against CC-induced muscle atrophy was determined by constructing an animal model with a series of behavioural tests, H&amp;E staining and related markers. Network pharmacology and molecular docking were used to preliminarily determine the mechanism and targets of NF against CC-induced muscle atrophy. The mechanisms of NF in treating CC-induced muscle atrophy were verified by western blotting. Molecular dynamics simulation (MD), drug affinity responsive target stability (DARTS) and surface plasmon resonance (SPR) were used to validate the key target of NF.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;After 13 days of NF treatment, the reduction of limb grip strength and hanging time in LLC model mice increased by 29.7% and 192.2% (&lt;i&gt;p&lt;/i&gt; ≤ 0.01; &lt;i&gt;p&lt;/i&gt; ≤ 0.001). Gastrocnemius and quadriceps muscles weight/initial body weight (0.98 ± 0.11 and 1.20 ± 0.17) and cross-sectional area of muscle fibres (600–1600 μm&lt;sup&gt;2&lt;/sup&gt;) of NF-treated mice were significantly higher than those of the model group (0.84 ± 0.10, 0.94 ± 0.09, 400–800 μm&lt;sup&gt;2&lt;/sup&gt;, respectively) (&lt;i&gt;p&lt;/i&gt; ≤ 0.01; &lt;i&gt;p&lt;/i&gt; ≤ 0.01; &lt;i&gt;p&lt;/i&gt; ≤ 0.001).

This study investigated the correlation of known sarcopenia biomarkers—adiponectin, myostatin, P3NP, CRP and TNF-α—measured from plasma-derived EVs with muscle mass, function and performance in an Osteoporosis Sarcopenia cohort at the Seoul National University Bundang Hospital.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Muscle mass was evaluated by measuring appendicular skeletal muscle mass (ASM) using dual X-ray absorptiometry and calculated as ASM/height&lt;sup&gt;2&lt;/sup&gt;.

The relative contributions of reduced muscle mass versus impaired muscle function to fall risk remain debated. Discrepant conclusions in previous studies exist due to divergent muscle health categorizations and parameter measurements. This study investigated longitudinal risk of falls across a spectrum of muscle health statuses among older people in the community.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Methods&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;Community-dwelling participants aged 65 years and older, undergoing annual health assessments, were enrolled between 2015 and 2023. Measurements included handgrip strength, walking speed and appendicular skeletal muscle mass. Dynapenia was defined as impaired muscle function with preserved muscle mass, presarcopenia was characterized as reduced muscle mass with maintained muscle function, and sarcopenia was identified as concurrent losses in both muscle mass and muscle function. Older people with normal muscle mass and muscle function were defined as having a robust muscle health status. Participants without a history of falls at baseline were monitored continuously and were censored if a fall incident was recorded during later yearly assessment. Kaplan–Meier and Cox regression analyses were used to compare fall risk across different muscle health statuses.&lt;/p&gt;\u0000 &lt;/section&gt;\u0000 \u0000 &lt;section&gt;\u0000 \u0000 &lt;h3&gt; Results&lt;/h3&gt;\u0000 \u0000 &lt;p&gt;The final analysis included a total of 863 participants with a mean age of 71.93 ± 6.62 years, and 57.58% were female. Compared with the other groups, the dynapenic group exhibited a lower physical activity, greater body mass index and slower gait speed. The participants with dynapenia experienced the highest fall incidence (27.15%). The hazard ratios (HRs) for fall were 2.65 (95% confidence interval [CI] = 1.72–4.08, &lt;i&gt;p&lt;/i&gt; &lt; 0.001) for dynapenia, 1.54 (95% CI = 0.92–2.57, &lt;i&gt;p&lt;/i&gt; = 0.095) for presarcopenia and 1.87 (95% CI = 1.04–3.33, &lt;i&gt;p&lt;/i&gt; = 0.034) for sarcopenia. After adjustment for multiple covariates, the fall risk remained significantly greater in the dynapenic group (HR = 2.10, 95% CI = 1.28–3.43, &lt;i&gt;p&lt;/i&gt; = 0.003) than in the sarcopenic group (HR = 1.31, 95% CI = 0.69–2.46, &lt;i&gt;p&lt;/i&gt; = 0.402).

Patients with chronic graft vs. host disease (cGVHD) after allogeneic haematopoietic cell transplantation (HCT) represent a high-risk cancer population with mortality risk explained by cGVHD severity, but also informed by baseline comorbidities, functional status before and after HCT, and cumulative toxicity from the procedure and its complications.

Skeletal muscle index (SMI) and fat index (FI) were quantified on CT imaging at the 3rd lumbar (L3) and 4th thoracic (T4) vertebra. SM Hounsfield units (HU) were obtained to evaluate SM density.
