Pregnancy in patients with chronic kidney disease undergoing dialysis.

Women with chronic kidney disease are less likely to become pregnant and are more susceptible to pregnancy complications when compared to patients with normal kidney function. As a result, these are considered high-risk pregnancies, both maternal and fetal. Over the years, there has been an increase in the incidence of pregnancies in dialysis patients, and an improvement in maternal and fetal outcomes.

Predictors of response to CDK4/6i retrial after prior CDK4/6i failure in ER+ metastatic breast cancer.

After disease progression on endocrine therapy (ET) plus a CDK4/6 inhibitor, there is no standardized sequence for subsequent treatment lines for estrogen receptor positive (ER+) metastatic breast cancer (MBC). CDK4/6i retrial as a treatment strategy is commonplace in modern clinical practice; however, the available prospective data investigating this strategy have had inconclusive results. To frame this data in a real-world context, we performed a retrospective analysis assessing the efficacy of CDK4/6is in 195 patients who had previous exposure to CDK4/6i in a prior treatment line at our institution.
