Observational Study
Effect of vitamin K1 on survival of patients with chronic liver failure: A retrospective cohort study.
The effectiveness of vitamin K1 for the treatment of liver failure has been controversial, and no studies have investigated the effect of vitamin K1 on the risk of death and coagulation function in patients with chronic liver failure. This study aimed to explore the effect of vitamin K1 on death risk and international normalized ratio in patients with chronic liver failure. From December 2013 to August 2017, this retrospective cohort study screened patients hospitalized for chronic liver failure (n = 80) who received routine treatment. ⋯ Male sex, age, ALB, TBIL, and ALP are potential risk factors for increased risk of death in these patients. Based on these findings, vitamin k1 can be used in patients with chronic liver failure. Prospective studies are still needed, however, to validate the role of vitamin K1 in the chronic liver failure.

Currently, there are few guidelines for the use of vitamin K1 in the maintenance treatment of long-acting anticoagulant rodenticide (LAAR) poisonings. We explored factors in the treatment of LAAR poisoning during the maintenance period in order to suggest feasible treatment models. Data from 24 cases of anticoagulant rodenticide poisoning in our hospital were collected from January 2013 to May 2016. ⋯ Only VKSTT (partial regression coefficient -1.133, 0.59, P = 0.035) had an obvious influence on the therapeutic dose of vitamin K1 required during the maintenance period. After an initial pulse therapy, the bleeding and coagulation functions were stabilized, and the patients were subsequently treated with vitamin K1 during the maintenance period. Over time, the maintenance dose of vitamin K1 (10-120 mg/d, intravenous drip) was gradually decreased and was not related to toxicant concentration.

Anticoagulant management of pregnant women with mechanical heart valve replacement during perioperative period.
To investigate the morbidity of complications and pregnancy outcomes in women with mechanical heart valve replacement who received low-dose oral anticoagulation treatment with warfarin throughout the pregnancy, compare the prognosis and complications of patients who were treated with single oral warfarin treatment or the "bridging" therapy treatment, investigate the influence of using vitamin K1 before emergency cesarean section delivery on postoperative warfarin anticoagulant effect and to explore an appropriate anticoagulant regimen during perioperative period for pregnant women with mechanical heart valve replacement. ⋯ The use of vitamin K1 preoperatively might result in warfarin resistance and discontinuation of warfarin therapy before selective CS might be more appropriate than application of vitamin K1. The "bridging" anticoagulation treatment which combines oral warfarin and subcutaneous LMWH might be more effective and safer than single oral warfarin therapy for patients with mechanical heart valve replacement during postoperative period, no matter selective or emergency CS. The safety of low-dose oral warfarin therapy throughout pregnancy is still under controversy.

Vitamin K is a potent regulator of vascular dynamics and prevents vascular calcification. Vitamin K is increasingly being recognized for its antioxidant and antiinflammatory properties. Recently we demonstrated that vitamin K1 (5 mg/kg) protects against streptozotocin-induced type 1 diabetes and diabetic cataract. The aim of this study was to determine whether the hypoglycemic action of vitamin K1 could inhibit early-onset diabetic nephropathy in a streptozotocin-induced rat kidney. ⋯ Vitamin K1 could be an important nutrient based interventional strategy for early onset diabetic nephropathy.
