Early outcomes of robotic retroperitoneal partial nephrectomy: evaluating surgical success with margin, ischemia, and complication score.
The objective of this study was to evaluate the minimum number of required cases for successful robotic retroperitoneal partial nephrectomy for an experienced surgeon in transperitoneal robotic surgery. ⋯ A total of 25 or more cases appear to be sufficient to provide optimal surgical results in robotic retroperitoneal partial nephrectomy for an experienced surgeon.

Accuracy of intrapartum cardiotocography in identifying acidemia at birth by umbilical cord blood gasometry in high-risk pregnancies.
The aim of this study was to evaluate the accuracy of intrapartum cardiotocography in identifying acidemia at birth by umbilical cord blood gasometry in high-risk pregnancies. ⋯ All three categories of intrapartum cardiotocography showed low sensitivity and high specificity for identifying acidemia at birth.

Collagen content and C-X-C motif chemokine ligand 12 expression in neoplastic breast stroma.
This study aimed to evaluate the expression of C-X-C motif chemokine ligand 12 and its C-X-C chemokine receptor type 4, and the tumor-stroma ratio using collagen stromal content of breast cancer samples, correlating it with clinicopathological data. ⋯ Low expression of C-X-C motif chemokine ligand 12 may be associated with a worse prognosis for breast cancer. Collagen staining analyzed using digital images represents an opportunity for clinical application and is indicative of the prognosis of the tumor microenvironment in breast carcinoma.

The clinical significance of lymphovascular space invasion in patients with low-risk endometrial cancer.
The aim of this study was to assess the effect of lymphovascular space invasion on recurrence and disease-free survival in patients with low-risk endometrial cancer. ⋯ lymphovascular space invasion is a prognostic risk factor for recurrence and distant metastasis and also a predictor of poorer disease-free survival outcomes in low-risk endometrial cancer.

Fetal vascular malperfusion score is linked with developing preeclampsia in women with gestational diabetes mellitus: a retrospective cohort study.
Fetal vascular malperfusion is associated with poor perinatal outcomes in women with preeclampsia and gestational diabetes mellitus. The aim of this study was to determine the association between fetal vascular malperfusion score and syncytiotrophoblast basement membrane thickness and clinicopathological variables, such as developing preeclampsia in women with gestational diabetes mellitus. ⋯ The gestational diabetes mellitus group displayed significantly higher fetal vascular malperfusion scores and thickening of the syncytiotrophoblast basement membrane than the control group. There is a correlation between developing preeclampsia and the fetal vascular malperfusion scores and the syncytiotrophoblast basement membrane thickness.
