Kallikrein (Padutin-Depot) was administered to 20 patients with obliterative atherosclerosis of the lower limbs of the II degree (19 patients) and IV degree (1 patient). The drug was given in the daily dose of 40 U i.m. for 28 days. An effect of kallikrein on the distance in intermittent claudication, rate of pain relieve after walking the maximal distance, blood flow in the lower limbs, and on the index of circulating aggregates have been determined. Clinical improvement has been noted after a 4-week therapy with kallikrein. The drug in a single dose of 40 U activates plasma fibrinolytic system for 5 hours and decreases the number of circulating aggregates (2-5 h). The authors explain kallikrein action as the release of endogenous bradykinin, which subsequently releases two epithelial mediators, i.e. PFG1 and EDRF.

Background: An accurate knowledge of a patient's risk of cord-level intraoperative neuromonitoring (IONM) data loss is important for an informed decision-making process prior to deformity correction, but no prediction tool currently exists.
Methods: A total of 1,106 patients with spinal deformity and 205 perioperative variables were included. A stepwise machine-learning (ML) approach using random forest (RF) analysis and multivariable logistic regression was performed.

Purpose: The effect of skeletal muscle mass of the trunk and extremities on sagittal imbalance of the spine before and after surgery for adult spinal deformity (ASD) has not been elucidated. The purpose of this study was to examine the correlation between reduced skeletal muscle mass of the trunk and extremities, as well as spinopelvic parameters, preoperatively, postoperatively and at least 2 years after surgery for ASD.
Methods: This retrospective observational study included 140 consecutive patients who had undergone surgery for ASD and were followed-up for at least 2 years and whose skeletal muscle mass could be measured preoperatively using whole-body dual-energy X-ray absorptiometry.

Unlabelled: Osteoporosis is often underrecognized and undertreated following periprosthetic fractures (PPF). Our study found that between 2010 and 2020, there has been no significant change in the rates of osteoporosis screening or treatment within 1 year following PPF. Orthopedic surgeons can play an integral role in helping to curtail the osteoporosis epidemic.

The advancements in medicine throughout the twentieth century have been largely attributed to animal studies. The initial step in researching an animal disease is to establish a model closely resembling the clinical circumstances in humans. Consequently, an excellent animal model is essential for almost any experimental research.
