Identifying Valid Algorithms for Number of Lines of Anti-Neoplastic Therapy in the Danish National Patient Registry Among Patients with Advanced Ovarian, Gastric, Renal Cell, Urothelial, and Non-Small Cell Lung Cancer Attending a Danish University Hospital.

Purpose: To develop algorithms to identify number of lines of anti-neoplastic therapy per patient based on the Danish National Patient Registry (DNPR) and identify which algorithm has the highest percentage agreement with a reference standard of documentation in medical records.

Patients And Methods: We included 179 patients diagnosed between January 1, 2012, and December 31, 2016, with stage II, III, or IV urothelial cell carcinoma or stage III or IV epithelial ovarian cancer, gastric adenocarcinoma, renal cell carcinoma, or non-small cell lung cancer (NSCLC). We developed two algorithms for number of lines of anti-neoplastic therapy based on dates and treatment codes (eg, "treatment with cisplatin" or "cytostatic treatment") in the DNPR.

Appendectomy, cholecystectomy and diagnostic laparoscopy conducted before pregnancy and risk of adverse birth outcomes: a nationwide registry-based prevalence study 1996-2015.

Background: Non-obstetric surgery conducted during pregnancy may increase the risk of adverse birth outcomes like small for gestational age, preterm birth, and miscarriage. Mechanisms are unclear but possibly longer lasting. We examined whether appendectomy, cholecystectomy and diagnostic laparoscopy conducted before pregnancy affect these outcomes.

Obstetric and non-obstetric surgery during pregnancy: A 20-year Danish population-based prevalence study.

Objectives: Population-based studies on use of non-obstetric and obstetric surgical procedures during pregnancy are sparse. Therefore, our objective was to estimate the prevalence of surgery during pregnancy, including potential time trends, overall and by trimester and describe the characteristics of pregnant women undergoing surgery.

Design: This study is a large nationwide cohort study.

MR angiography demonstrates a positive correlation between placental blood vessel volume and fetal size.

Purpose: While intrauterine growth restriction is often associated with placental dysfunction or abnormal morphology, the link between fetal weight and the placental delivery capacity of blood has not been studied in detail. The purpose of this study was to investigate the relationship between the fetal placental blood volume (FPBV) and fetal length, fetal weight and fetal head circumference using a non-invasive approach.

Methods: Placentas from normal pregnancies terminated with elective cesarean section were included.
