Optimal theranostic SPECT imaging protocol for 223radium dichloride therapy.

Radium dichloride image-based individual dosimetry requires an optimal acquisition and reconstruction protocol and proper image correction methods for theranostic applications. To assess this problem, radium-223 dichloride SPECT images were acquired from a Jaszczak simulator with a dual-headed gamma camera, LEHR collimator, 128 × 128 matrix, and total time of 32 minutes. A cylindrical PMMA phantom was used to calibrate the measurements performed with Jaszczak.

Functional Evaluation and Pain Symptomatology of the Foot and Ankle in Individuals with Severe Obesity - Controlled Transversal Study.

 The present study aims to evaluate the prevalence of foot and ankle pain complaints, radiographic parameters, and functional performance in subjects with severe obesity (body mass index [BMI] > 40) who are candidates to bariatric surgery.  Forty severely obese patients were evaluated at a bariatric surgery outpatient facility. These severely obese subjects (BMI > 40) were divided into two subgroups: those with BMI < 50 (n = 24) and BMI > 50 (n = 16).

A Randomized Controlled Trial Investigating the Effects of Undulatory, Staggered, and Linear Load Manipulations in Aerobic Training on Oxygen Supply, Muscle Injury, and Metabolism in Male Recreational Runners.

Background: Taper is considered as a strategy to avoid overtraining and increase peak performance in athletes. Because aerobic exercise increases the level and duration of independence during the lifespan, the participation of recreational athletes has increased in running events around the world. However, the effects of using load reduction in their training and aerobic performance are still not well known.

Back pain and sagittal spine alignment in obese patients eligible for bariatric surgery.

Objective: The objective of this research was to evaluate the prevalence of cervical and lumbar pain in obese patients eligible for bariatric surgery and to investigate possible changes in sagittal spine alignment in these patients.

Methods: The following parameters were compared in 30 obese patients and a control group of 25 non-obese volunteers: body mass index, prevalence of cervical and lumbar pain assessed by visual analog scale (VAS), Neck Disability Index [NDI] and Oswestry Disability Index [ODI], as well as radiographic parameters of the spine and pelvis measured with Surgimap software.

Results: The cervical and lumbar VAS and the NDI and ODI were significantly worse in obese patients.

Turner syndrome patients' ultrasound profile.

Objective: Evaluate the uterus and ovary by ultrasonography, considering the genotype, pubertal development and hormonal levels.

Materials And Methods: Cross-sectional study of 53 (7-53 years old) patients with Turner syndrome considering pubertal development by Tanner stage, puberty induced or not and the ultrasound examination.

Results: The patients were 10 prepubertal and 43 with pubertal signs.

Isolated premature pubarche: report of anthropometric and metabolic profile of a Brazilian cohort of girls.

Aims: Isolated premature pubarche (PP) is commonly caused by premature adrenarche (PA), and links between PA, children born small for gestational age (SGA) and insulin resistance have already been made in some populations.

Subjects And Methods: We assessed anthropometric data, pubertal landmarks and metabolic profile at diagnosis and during the study in 52 girls with the diagnosis of isolated PP from a Brazilian cohort.

Results: The prevalence of obesity (25%), dyslipidemia (63.
