Association Between Digoxin Use and Cancer Incidence: A Propensity Score-Matched Cohort Study With Competing Risk Analysis

Repurposing cardiac glycosides for anticancer treatment: a review of clinical studies

Cardiac glycosides (CGs), which are traditionally used for heart disease, show promise for cancer therapy. However, there is a lack of a comprehensive review of clinical studies in this area, and so far, CGs have not been widely integrated into clinical cancer treatment. This review covers clinical studies from the past five years, highlighting the potential of CGs to reduce cancer risk, enhance chemotherapy effectiveness, mitigate chemotherapy-induced side effects and improve quality of life. Future clinical trials should personalize the dosage of CGs, integrate molecular testing and investigate immunogenic cell death induction and the potential of CGs for treating bone cancer and metastasis. Optimizing the repurposing of CGs for anticancer treatment requires consideration of specific CGs, cancer types and concurrent medications.

Exploring the role of CDCA4 in liver hepatocellular carcinoma using bioinformatics analysis and experiments

Liver hepatocellular carcinoma (LIHC) encompasses diverse therapeutic approaches, among which targeted therapy has gained significant prominence in recent years. The identification of numerous targets and the increasing clinical application of targeted drugs have greatly improved LIHC treatment. However, the precise role of CDCA4 (Cell Division Cycle Associated 4), as well as its underlying mechanisms and prognostic implications in LIHC, remains unclear. CDCA4 expression levels in LIHC were analyzed using multiple databases including the cancer genome atlas (TCGA), gene expression profiling interactive analysis (GEPIA), and ULCAN, as well as the datasets E_TABM_36, GSE144269, GSE14520, and GSE54236. The prognostic value of CDCA4 was then evaluated. Subsequently, the association between CDCA4 and immune cells was investigated. Enrichment analysis (GSEA) was utilized to investigate the functional roles and pathways linked to CDCA4. Additionally, the methylation patterns and drug sensitivity of CDCA4 were examined. A predictive model incorporating immune genes related to CDCA4 was developed. The TISCH dataset was used to investigate the single-cell expression patterns of CDCA4. Finally, validation of CDCA4 expression levels was conducted through RT-PCR, Western blotting, and immunohistochemistry. CDCA4 exhibited significant overexpression in LIHC and demonstrated significant correlations with clinical features. High expression of CDCA4 is associated with a poorer prognosis. Analysis of immune infiltration and enrichment revealed its association with the immune microenvironment. Furthermore, its expression is correlated with methylation and mutation patterns. CDCA4 is associated with 19 drugs. Prognostic models utilizing CDCA4 demonstrate favorable effectiveness. T cell subtypes were found to be associated with CDCA4 through single-cell analysis. The conclusive experiment provided evidence of significant upregulation of CDCA4 in LIHC. The high expression of CDCA4 in LIHC is associated with prognostic significance and is highly expressed in T cell subtypes, providing a new therapeutic target and potential therapeutic strategy for LIHC.

Real-world evidence of hyperbaric oxygen therapy on cardiovascular outcomes in patients with chronic osteomyelitis

BACKGROUND

The effectiveness of hyperbaric oxygen (HBO) therapy for chronic osteomyelitis remains inconclusive. In particular, recent studies have shown that chronic osteomyelitis is a crucial risk factor for cardiovascular diseases. However, the preventive effect of HBO on cardiovascular events has not been reported in patients with chronic osteomyelitis.

METHODS

We conducted a population-based cohort study to evaluate the impact of HBO on patients with chronic osteomyelitis. Overall, 5312 patients with chronic osteomyelitis were selected from the Taiwan National Health Insurance Database to evaluate the impact of HBO in patients with chronic osteomyelitis. Propensity-score (PS) matching and inverse probability weighting (IPTW) were employed to balance covariates between the HBO and non-HBO groups. The primary outcome was all-cause mortality. The secondary outcomes were myocardial infarction (MI) and stroke hospitalisation. Furthermore, we evaluated the appropriate timing for HBO intervention by the restricted cubic spline (RCS) functions.

RESULTS

After 1:4 PS-matching, the HBO group (n = 265) was associated with lower 1-year mortality (hazard ratio [HR], 0.49; 95 % confidence interval [CI], 0.25-0.95) than the non-HBO group (n = 994); this was consistent with the IPTW weighting results (HR, 0.25; 95 % CI, 0.20-0.33). The risk of stroke was lower in the HBO group (HR, 0.46; 95 % CI, 0.34-0.63) than that in the non-HBO group. However, HBO therapy failed to reduce the risk of MI. Using the RCS model, patients with intervals within 90 days (HR, 1.38; 95 % CI, 1.04-1.84) presented a significant risk of 1-year mortality. After 90 days, as the length of interval increased, the risk gradually decreased and became insignificant.

CONCLUSION

The present study revealed that adjunctive HBO could benefit the 1-year mortality and stroke hospitalisation in patients with chronic osteomyelitis. HBO was recommended to be initiated within 90 days of chronic osteomyelitis hospitalisation.

The effectiveness of Fuzi in combination with routine heart failure treatment on chronic heart failure patients

ETHNOPHARMACOLOGICAL RELEVANCE

Fuzi, Aconiti Lateralis Radix Praeparata, is widely used in Traditional Chinese Medicine (TCM) for the treatment of acute heart failure (HF) for 2000 years. However, the clinical evidence of Fuzi in the treatment of chronic HF is limited, especially when used in combination with Western medications.

MATERIALS AND METHODS

This population-based propensity score (PS)-matched cohort study aimed to evaluate the effectiveness of Fuzi on the chronic HF. From 4753 chronic HF patients who had used TCM herbal medicine, we performed 1:1 PS matching and selected target patients with (n = 921) and without (n = 921) Fuzi use for further analysis. The primary outcomes were all-cause mortality and composite cardiovascular (CV) outcomes. Hazard ratio (HR) was calculated by Cox proportional hazard regression and the competing risk analysis. The dose-response relationship and the association between the initiation of TCM herbal medicine and the primary outcomes were evaluated by restricted cubic spline (RCS) functions.

RESULTS

There was no difference in all-cause mortality (HR, 0.99; 95% confidence interval [CI], 0.76-1.27) and composite CV outcomes (HR, 0.96; 95% CI, 0.84-1.11) between the Fuzi user and non-user groups. For CV safety issue, the result showed that Fuzi use was not associated with a higher risk of cardiac arrhythmias (HR, 1.03; 95% CI, 0.83-1.29). The dose-response relationship showed that Fuzi cumulative dose (≥150g) was associated with lower composite CV risk (HR, 0.76; 95% CI, 0.59-0.99). In addition, the RCS model showed that late initiation (≥2.5 years) of TCM herbal drugs in chronic HF patients had a higher risk of all-cause mortality (HR, 1.81; 95%CI, 1.07-3.08).

CONCLUSIONS

This study is the first real-world evidence to demonstrate the effect of Fuzi combined with routine HF treatment. Importantly, the result indicated that long-term Fuzi use had a significant benefit in preventing cardiovascular events. The late initiation of TCM herbal drugs was associated with a higher risk of all-cause mortality. Further clinical trials are needed to support or undermine the assumption of using Fuzi and current Western medications to treat chronic HF.
