AI Article Synopsis
- Diabetes increases the risk of developing certain types of cancer, but the incidence of diabetes occurring after a cancer diagnosis has been unclear.
- A systematic review and meta-analysis of 34 studies showed that cancer patients have a significantly higher risk (RR = 1.42) of developing diabetes compared to cancer-free individuals, especially in the first year after diagnosis (RR = 2.06).
- The study suggests that while new-onset diabetes is linked to cancer, more extensive research is needed to explore this association and its causes, particularly across different cancer types.
Article Abstract
Background: Diabetes increases the risk of certain types of cancer. However, the literature regarding the incidence of diabetes after cancer diagnosis is inconsistent. We aimed to assess whether there was a higher incidence of diabetes among cancer patients by performing a systematic review and meta-analysis of results from cohort studies. Methods: A systematic electronic literature search was carried out from cohort studies regarding the incidence of diabetes in cancer patients, using the databases PubMed (MEDLINE), Embase, Web of Science, and the Cochrane Library. Random-effects meta-analyses were conducted to pool the estimates. Results: A total of 34 articles involving 360,971 cancer patients and 1,819,451 cancer-free controls were included in the meta-analysis. An increased pooled relative risk (RR) of 1.42 (95% confidence interval (CI): 1.30−1.54, I2 = 95, τ2 = 0.0551, p < 0.01) for diabetes in cancer patients was found compared with the cancer-free population. The highest relative risk was observed in the first year after cancer diagnosis (RR = 2.06; 95% CI 1.63−2.60). Conclusions: New-onset diabetes is positively associated with cancer, but this association varies according to cancer type. More prospective studies with large sample sizes and longer follow-up times are advocated to further examine the association and the underlying mechanisms.

BACKGROUND Studies using transgenic mouse models have demonstrated that estrogen is necessary for the development of cervical cancer, particularly in tissues responsive to estrogen. Estrogen also protects cervical cancer cells from apoptosis, suggesting its role in the survival and persistence of cancer cells. CASE REPORT An 84-year-old woman with diabetes mellitus, hypertension, and stage III chronic renal failure was diagnosed with cervical squamous cell carcinoma, FIGO stage IB2.

Angiogenesis describes the sprouting of blood vessels from existing vasculatures and it plays a pivotal role in disease progress such as diabetes, age-related macular degeneration and cancer. However, the most widely used anti-angiogenic agents targeting vascular endothelial growth factor (VEGF) pathway still lacked of specificity and therapeutic efficacy. To establish a method suitable for high-throughput drug screening and faithfully recapitulate the feature of in vivo angiogenesis, we generated a PECAM1-mRuby3-secNluc; ACTA2-EGFP dual reporter human pluripotent stem cell (hPSC) line and utilizing the cell line to establish a visualized and quantifiable in vitro angiogenesis model with stem cell-derived vascular organoid.

Background: Nipple-sparing mastectomy (NSM) is infrequently performed in older women, at least in part owing to concerns regarding age-related complications. We describe postoperative outcomes of NSM in older women and risk factors for complications, with the goal of informing patient selection and decision-making.
Patients And Methods: Cases of NSM with immediate implant-based reconstruction were identified from an institutional database (2009-2019).
