Portomesenteric vein thrombosis in sleeve gastrectomy: a 10-year review

Background

Worldwide, the laparoscopic sleeve gastrectomy (LSG) is becoming the dominant bariatric procedure due to its reliable weight loss and low complication rate. Portomesenteric vein thrombosis (PVT) is an uncommon complication of LSG with an incidence of .3% to 1% and can lead to serious consequences, such as bowel ischemia and death.

Pregnancy in patients on maintenance hemodialysis: seven cases report and 169 reported cases review

Objective To analyze and summarize the cases of pregnancy on maintenance hemodialysis (MHD), and review the literature. Methods Seven cases of pregnancy and childbirth in patients on MHD in the First Affiliated Hospital of Zhejiang University from Jan 2009 to Dec 2017 were analyzed, and the literature about pregnancy in patients on MHD reported in Pubmed and Web of Science database was retrieved. Both maternal and fetal outcome were studied. Results There are seven pregnant MHD patients in this center, among whom six patients went through a smooth pregnancy and one patient had intra-uterine fetal death at 14 weeks of pregnancy. The six patients had preterm labor. Among six fetuses, four grew in good health and developed well, one had physical development retardation and one had heart malformation at born. In the literature, 169 cases reported pregnant patients and 182 fetuses were evaluated, of which 145 live infants were delivered, 79.67% overall fetal survival rate, with gestational age of (32.94±3.34) weeks. In 164 delivered fetuses, 147 were preterm labor (89.63%). The weight of live births was (1824±609) g. There were no maternal deaths. Fetal survival rate was zero in＜20 weeks of gestational age, 20-24 weeks was 14.29%, 25-27 weeks was 45.45%, ≥28 weeks was 94.44%. The fetal survival rate was higher in pregnant woman receiving hemodialysis≥28 hours weekly compared to women receiving ＜16 hours weekly (92.31% vs 52.94%, P=0.02). Conclusions There are still a very high maternal and fetal complication rate in hemodialysis patients, especially in fetus. Gestational age≥28 weeks has a high fetal survival rate. Intensive dialysis during pregnancy may benefit higher fetal survival rate.     

Considerations for Comprehensive Assessment of Genetic Predisposition in Familial Breast Cancer

About 10–15% of breast cancer cases are family related, classified as familial breast cancer. The disease was first reported in 1866 and determined to be an autosomal dominant genetic disease in 1971. Germline mutations in BRCA1 were discovered and deemed as the first genetic predisposition for the disease in 1994. By now, genetic predispositions for about 40% of familial breast cancer families have been identified. New molecular genetic approaches currently under development should accelerate the process to identify the full spectrum of genetic predispositions for the disease, thereby enabling a better understanding of the genetic basis of the disease and therein providing benefit to high‐risk patients.
