Summary: During the 5-year follow-up, individuals with both diabetes and gastric cancer who received metformin treatment had a significantly lower risk of all-cause death compared to those who did not receive treatment. The use of metformin was associated with a decreased risk of mortality among this population.

Summary: The risk of cardiovascular disease (CVD) death in patients with localized prostate cancer (PCa) was determined by risk stratification. The study found that in the low- and intermediate-risk groups, CVD-related death surpassed PCa almost immediately, while in the high-risk group, CVD surpassed PCa approximately 90 months later. Patients with localized PCa have a higher risk of CVD-related death compared to the general population.

Summary: In patients with type 2 diabetes, the use of metformin is associated with significantly lower risks of bacterial pneumonia, invasive mechanical ventilation, and respiratory cause of death. Longer duration of metformin use is also associated with lower hazard ratios for these risks.

Summary: This study evaluated the impact of post-diagnostic metformin or statin use and duration on the risk of biochemical recurrence in a racially-diverse cohort of Veterans. The results showed that post-diagnostic metformin use was not associated with biochemical recurrence, but its duration was associated with a reduced risk. On the other hand, statin use was associated with a reduced risk of biochemical recurrence, and this association was observed in all racial groups. In conclusion, post-diagnostic metformin and statin use have the potential to prevent biochemical recurrence in men diagnosed with prostate cancer.

Summary: The relationship between metformin use and prostate cancer risk is controversial, with metformin use associated with increased risk of high-grade and overall prostate cancer. SNPs involved in metformin metabolism did not modify disease risk association, but two SNPs from the GWAS study did.

Summary: Despite substantial progress in cancer therapy, patients with cancer still face a high risk of suicide. This study comprehensively assessed the suicide mortality risk in cancer patients and found a significantly increased risk compared to the general population. The risk was strongly related to cancer prognosis, stage, time since diagnosis, and geographic region. Therefore, cancer patients, especially those with specific risk factors, should be closely monitored for suicidality and receive specialized care to reduce the risks of suicide.

Summary: This study analyzed the impact of statins and metformin on treatment outcomes in patients with castration-resistant prostate cancer. The results showed inconsistent associations between the use of statins and metformin and radiographic progression-free survival (rPFS), metastasis-free survival (MFS), and overall survival (OS) across different trials. The pooled analysis revealed that statin use was significantly associated with a reduced risk of death in enzalutamide-treated patients, while metformin use was not significant.

Summary: This study found that metformin use in patients with diabetes and COVID-19 is associated with lower markers of inflammation, renal ischemia, and thrombosis, as well as fewer hospitalized days and lower intubation rate. These findings support the potential benefits of metformin in the treatment of COVID-19 in patients with diabetes.

Summary: There is conflicting evidence regarding the association between metformin treatment and prostate cancer risk in diabetic men. Previous-year exposure to metformin is positively associated with prostate cancer risk, while exposure 2-7 years ago is negatively associated with risk. Further confirmation and understanding of these positive and negative associations are needed.

Summary: This study aimed to evaluate the factors associated with a short time interval to prostate-specific antigen (PSA) failure in order to identify patients who would benefit from treatment escalation. The results showed that young age, high PSA levels, and high Gleason score were associated with a shorter time to PSA failure. These patients may benefit from treatment intensification and should be included in prospective randomized clinical trials.

Summary: Research suggests that different antihypertensive drugs may be associated with the survival of ovarian cancer patients, with ACE inhibitors potentially improving survival rates. There appears to be no immediate impact of antihypertensive drugs on ovarian cancer survival, but over time, particularly with longer follow-up, certain medications may show benefits in improving survival outcomes. Further studies are needed to confirm the potential survival benefits of ACE inhibitors for women with ovarian cancer.

Summary: External controls are primarily used in single-arm trials of rare diseases, with little investigation into their use in common diseases. This study aimed to emulate a large cardiovascular outcome trial of type 2 diabetes and found that different comparator groups, time periods, and adjustment methods can significantly impact the results. These factors must be carefully considered in the design of trial emulation studies.

Targeted vaccination for immigrants under 50 years old is recommended to reduce the risk of varicella.

Summary: The COVID-19 pandemic has sparked a surge in observational studies assessing the safety and effectiveness of various treatments, including hydroxychloroquine and renin-angiotensin-aldosterone system inhibitors. Many of these studies have been found to have issues with immortal time bias and selection bias, highlighting the importance of addressing these biases in future research.

Summary: The study identified that increased levels of OAS1 protein are associated with reduced susceptibility and severity of COVID-19, providing evidence for a protective role of OAS1 in adverse outcomes. This suggests that pharmacological agents that increase OAS1 levels could be prioritized for drug development against COVID-19. The variant of the OAS1 gene associated with decreased risk of death in COVID-19 patients encodes an enzyme critical for the innate immune response to viral infections.

Summary: The study found that circulating levels of IGF-I and IGFBP-3 in breast cancer patients are significantly associated with recurrence-risk, while the correlation with IGFBP-7 levels is weaker. There is a significant interaction between IGFBP-7 levels and recurrence-risk in patients with IGF-IRm positivity.
