BackgroundThe incidence of secondary displacement in fractures of the greater tuberosity of the humerus remains high, irrespective of whether conservative or surgical treatment is administered. However, the specific risk factors contributing to secondary displacement of the greater tuberosity of the humerus have not been previously reported. The primary objective of this study was to analyze the risk factors associated with secondary displacement of the greater tuberosity of the humerus and to summarize corresponding guidelines for clinical diagnosis and treatment.MethodsA retrospective analys

Background. Surgical removal of mandibular third molars results in pain, swelling and bony defects, causing prolonged postoperative recovery. The growth factors present in platelet-rich plasma (PRP) can accelerate the healing, thereby shortening postoperative recovery period. This study was undertaken to evaluate the role of PRP in postoperative socket healing, pain, swelling and bone regeneration following surgical removal of impacted mandibular third molars. Methods. The present case‒control study was conducted on 20 patients with identical bilateral mandibular third molar impaction. PRP was

Background and ObjectiveDue to the frequency of meal ingestion, individuals spend the majority of the day, ~18 h, in a status of post-prandial (PP) stress. Remnant-like lipoprotein particles (RLPs) are predominant in PP phase playing an important role in the development of atherosclerosis. Endothelial progenitor cells (EPCs) have been suggested to play a role in vessel wall homeostasis and in reducing atherosclerosis. However, there is no information about peripheral blood EPCs number following PP stress. We investigated the association between circulating EPCs levels and extent of PP lipemia

Objectives The objective of this study was to compare the use of the feline Glasgow Composite Measured Pain Scale (CMPS-f) at home and in a veterinary hospital. The hypothesis was that pain-free cats would score higher in the CMPS-f when in a stressful situation than when calm and relaxed; that is, healthy but stressed cats could appear to be in discomfort or pain. Methods Healthy, non-painful adult cats owned by clinical staff were included in a prospective clinical trial with two observers (caregiver [CG] and researcher).

Patient Reported Outcome Measurement Information System (PROMIS) is a validated measure of outcomes after foot and ankle surgery. To our knowledge, no study has compared PROMIS scores between Weber subtypes. Our study thus examines whether Weber fracture subtype impacts surgical outcomes as measured by PROMIS scores.
