Background Age, race, and gender differences in coagulation status of healthy volunteers have been reported in previous case series; however, rigorous multivariate analysis adjusting for these factors is lacking. We aimed to investigate the effects of age, race, and gender on baseline coagulation status in healthy volunteers. Methods Thirty healthy volunteer controls with no history of bleeding or thrombotic events and no previous anticoagulant or antiplatelet use were recruited. Citrated and heparinized blood samples were drawn, and kaolin and platelet-mapping thromboelastography (TEG) assays performed. Results Thirty participants had a mean age of 37, mean body mass index of 29 kg/m2, and were 47% African-American and 70% female. Women were significantly older than men (40 ± 11 y vs 28 ± 7 y, P = .002); there were no significant differences in demographics by race. Multivariate analysis of variance for the effect of age, race, and gender across TEG parameters yielded evidence for gender differences in hypercoagulability (Pillai’s trace P = .02), which appear to be driven by differences in K-time, alpha angle, maximal amplitude, and G parameter. Women were hypercoagulable compared to men, as manifested by shorter K-time, steeper alpha angle, higher maximal amplitude, and larger G parameter. Discussion Women at baseline have relatively hypercoagulable fibrin deposition kinetics, platelet contributions to clot formation, and overall clot strength compared to men, even when adjusted for age and race. Additional research is needed to specifically detail the key patient-level factors, clinical implications, and opportunities for tailored therapy related to gender-associated hypercoagulability.
Cytoreductive surgery with heated intraperitoneal chemotherapy (CRS-HIPEC) is traditionally an open operation given the dissection required during cytoreduction. There are reports of minimally invasive HIPECs, but CRS to an accepted completeness of cytoreduction (CCR) has been described less frequently. We report a patient with metastatic low-grade mucinous appendiceal neoplasm (LAMN) to the peritoneum treated with robotic CRS-HIPEC. A 49-year-old male presented to our center following a laparoscopic appendectomy at an outside facility with final pathology showing LAMN. He had a peritoneal cancer index (PCI) score of 5 determined by diagnostic laparoscopy. Given the small amount of peritoneal disease, he was deemed a candidate for robotic CRS-HIPEC. Cytoreduction was completed robotically with a CCR score of 0. He then received HIPEC with mitomycin C. This case shows the feasibility of robotic-assisted CRS-HIPEC for select LAMNs. When appropriately selected, we advocate for the continued use of this minimally invasive approach.
Factor XIII deficiency is a rare cause of post-operative bleeding. It poses a diagnostic challenge as standard coagulation tests including prothrombin time, international normalized ratio, and activated partial thromboplastin time are usually normal in factor XIII deficiency. We present the case of our patient, a 19-year-old male with acquired factor XIII deficiency diagnosed after ballistic injury with a post-operative course complicated by hemorrhage. This case demonstrates an uncommon cause of coagulopathy, acquired factor XIII deficiency, and the challenges it poses to post-operative management. The diagnosis of acquired factor XIII deficiency may be challenging, but a high clinical suspicion is imperative to avoid a missed diagnosis and delayed treatment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
