Background and aim: The practicability of computing dose calculation on cone beam CT (CBCT) has been widely investigated. In most clinical scenarios, the craniocaudal scanning length of CBCT is found to be inadequate for localization. This study aims to explore extended tomographic localization and adaptive dose calculation strategies using Hounsfield unit (HU) corrected CBCT image sets. Materials and methods: Planning CT (pCT) images of the Rando phantom (T12 -to-midthigh) were acquired with pelvic-protocol using Biograph CT-scanner...

Numerous foundational movements performed during basketball are predicated on underlying power-related attributes, including speed, change-of-direction, and jumping. Accordingly, fitness testing batteries for basketball have incorporated an assortment of linear speed tests, change-of-direction tests, and jump tests. However, due to the wide variety of testing options it is difficult for basketball practitioners to select appropriate testing protocols for the assessment of power-related attributes. As a result, there is a need to review the relevant literature to identify game-specific, power-related attributes important in basketball and the most appropriate tests available to assess power-related attributes for basketball practitioners...

OBJECTIVE: To quantify changes in motor function, sensation, and lower extremity quality of life following anterior lateral thigh free flap (ALT) resection. METHODS: This mixed methods study contained both a prospective cohort arm (n = 20) and retrospective cross-sectional arm (n = 20). In both arms, patients underwent formal motor and sensation testing of the ipsilateral and contralateral thigh by sphygmomanometry and monofilament testing. In the prospective arm, data was collected preoperatively and at the 6-month and 1-year follow-up visits...

OBJECTIVE: To determine the 6-month follow-up effects after intentional 6-month weight loss alone (WL) and after weight loss with aerobic exercise (AEX + WL) on body composition, glucose metabolism, and cardiovascular disease risk factors in older postmenopausal women and to identify the mechanisms for weight regain. METHODS: Women (n = 65, BMI > 25 kg/m2 ) underwent maximal oxygen consumption testing, dual-energy x-ray absorptiometry, computed tomography scans, and oral glucose tolerance tests before and after 6 months of AEX + WL or WL and at 12 months ad libitum follow-up...

PURPOSE: The aim of the study was to analyze the correlations between the expression of glucose transporters GLUT-1, GLUT-4, and GLUT-9 in human term placenta and selected maternal and fetal parameters in pregnancies complicated by diabetes mellitus (DM). MATERIALS AND METHODS: Placental samples were obtained from healthy control (n = 25) and diabetic pregnancies, including diet-controlled gestational diabetes mellitus (GDMG1) (n = 16), insulin-controlled gestational diabetes mellitus (GDMG2) (n = 6), and pregestational DM (PGDM) (n = 6)...

The aim of this study were to compare isometric midthigh pull (IMTP) peak force (PF), time-specific force values (100-, 150-, and 200 ms), rate of force development (RFD) at predetermined time bands (0-100, 0-150, and 0-200 ms) and net forces between 2 commonly adopted hip joint angles (145°[hip145] and 175°[hip175]) with a 145° standardized knee angle. Twenty-eight collegiate athletes (age: 21.7 ± 1.5 years, height: 1.75 ± 0.08 m, mass: 81.5 ± 8.4 kg) performed 2 IMTP trials at each hip joint angle in a randomized counterbalanced order...

RANDOMIZED CONTROLLED TRIAL
Joshua L Hudson, Jung Eun Kim, Douglas Paddon-Jones, Wayne W Campbell
Background: Emerging research suggests that redistributing total protein intake from 1 high-protein meal/d to multiple moderately high-protein meals improves 24-h muscle protein synthesis. Over time, this may promote positive changes in body composition. Objective: We sought to assess the effects of within-day protein intake distribution on changes in body composition during dietary energy restriction and resistance training. Design: In a randomized parallel-design study, 41 men and women [mean ± SEM age: 35 ± 2 y; body mass index (in kg/m2 ): 31...

AIMS: To investigate the effects of 24 weeks of treatment with liraglutide added to basal/bolus insulin on anthropometric and metabolic parameters in overweight participants with type 1 diabetes. METHODS: In a double-blinded cross-over fashion, 15 participants were randomly assigned (1:1) to receive placebo (saline solution) or liraglutide for 24 weeks including a 1-month titration period from 0.6 to 1.2 to 1.8 mg, in addition to their insulin. The treatment was followed by a 1-month wash-out period...

BACKGROUND: Persistent sciatic artery (PSA) is a rare congenital anomaly of the circulation of the lower limb that results from the persistence of an artery that normally regresses early in embryonic development. PSA is usually an incidental finding and is exceedingly rare to find bilaterally. CASE REPORT: We present the case of a rare presentation of PSA that resulted in a favorable outcome for a patient who sustained a gunshot wound to his midthigh and discuss the history, embryology, anatomy, classification schema, imaging evaluation, complications, diagnosis, and management of PSA...

High-resolution CT angiogram (CTA) has replaced traditional diagnostic angiography as the main preoperative imaging modality for vascular surgery patients. Although the use of CTA is increasing for arterial imaging, it has not been used routinely for vein mapping. The goal of this study was to evaluate the accuracy of CTA for venous anatomy and compare it to a standard venous duplex ultrasound (DUS). When the vein was used for bypass, the quality and size of the vein were evaluated in the operating room. As part of a preoperative workup before lower extremity revascularization, 16 patients underwent a CTA followed by a DUS...

PURPOSE: To determine predictors of recanalization in patients treated with endovenous cyanoacrylate. METHODS: Follow-up by serial clinical and duplex examinations was performed at 1 week, 1 month, 6 months, 12 months, and 24 months of 108 legs in 55 patients (21 men, median age 65 y) with primary varicose veins treated with endovenous cyanoacrylate. Cox regression analysis was used to examine venous characteristics before the procedure: diameter of great saphenous vein (GSV), treatment length of GSV, presence of incompetent perforators, clinical severity of varicose vein, and experience of operator as predictors of recanalization...

OBJECTIVE Long-segment injuries to large peripheral nerves present a challenge to surgeons because insufficient donor tissue limits repair. Multiple supplemental approaches have been investigated, including the use of Schwann cells (SCs). The authors present the first 2 cases using autologous SCs to supplement a peripheral nerve graft repair in humans with long-term follow-up data. METHODS Two patients were enrolled in an FDA-approved trial to assess the safety of using expanded populations of autologous SCs to supplement the repair of long-segment injuries to the sciatic nerve...

PURPOSE: Aging is associated with a gradual loss of muscle mass, which some have suggested to be accelerated by short periods of muscle disuse due to medical illness. We investigated the effect of hospitalization on skeletal muscle mass in acutely ill geriatric patients with focus on the relationship between systemic inflammatory marker C-reactive protein (CRP) and changes in muscle mass, as well as the influence of resistance training upon muscle mass. METHOD: Unilateral leg press resistance exercise was conducted daily during the hospital period...

We report the case of a two and a half-year-old girl who presented with injury to the right thigh along with a discharging sinus in the midthigh region following a nonorthopaedic surgical procedure. Radiographs of the thigh indicated osteomyelitis of the femoral diaphysis with pathological fracture. During follow-up examination, shortening was observed in the affected limb, along with complete separation of the femoral epiphysis with partial resorption of the femoral head. A few cases of physeal separation of the femoral head following osteomyelitis of the femoral diaphysis have been reported in the published literature, but still it may go undiagnosed until late stages because of the lack of awareness among orthopaedicians about this entity...
