Treat, follow-up, or discharge? An aid in sonographic decisions for the borderline centered neonatal/infantile hips.

Aim: To investigate whether linear measurements or ratios on the Graf's "standard plane" ultrasound images of the neonatal/infantile hip, can support the clinically important differentiation between type I and type II hips.

Material And Methods: A total of 60 Graf type II hips and 124 randomly selected Graf type I hips, matched to the gestational age at delivery, birth weight, delivery mode, and age at the time of the examination, were identified through our hip screening service, during a period of two years. The images were diagnostically suitable, following anatomical identification and usability check, according to Graf.

Prognostic value of combined preoperative phase angle and handgrip strength in cardiac surgery.

Objectives: Phase angle (PA) constitutes a bioelectrical impedance measurement, indicating cell membrane health and integrity, hydration, and nutritional status. Handgrip strength (HS) has been also associated with body composition, nutritional status, inflammation, and functional ability in several chronic diseases. Although their prognostic significance as independent biomarkers has been already investigated regarding the outcomes of a cardiac surgery, our study is the first one to assess the combined predictive value of preoperative PA and HS.

The aim of this study was to investigate the prevalence of SO in patients with NDS, including stroke, spinal cord, and traumatic brain injuries.

Evaluation of Femoral Bone Fracture Healing in Rats by the Modal Damping Factor and Its Correlation With Peripheral Quantitative Computed Tomography.

Introduction Monitoring the progress of fracture healing is essential in order to establish the appropriate timing that ensures adequate bone strength for weight-bearing. In the present experimental study on a rat model of femoral fracture healing, the measurement of bone density and strength by peripheral quantitative computerized tomography (pQCT) was correlated with the modal damping factor (MDF) method. Methods Four groups of 12 male six-month-old Wistar rats each were anesthetized and submitted to baseline femoral pQCT and MDF scanning, followed by aseptic midshaft osteotomy of the right femur which was fixed by a locking intramedullary nail technique.
