PURPOSE: To compare the clinical and radiographical long-term outcome of microfracture (MFX) and first-generation periosteum-covered autologous chondrocyte implantation (ACI-P). METHODS: All subjects (n = 86) who had been treated with knee joint ACI-P or microfracture (n = 76) with a post-operative follow-up of at least ten years were selected. Clinical pre- and post-operative outcomes were analyzed by numeric analog scale (NAS) for pain, Lysholm, Tegner, IKDC, and KOOS score...

Background In December 2014 Slovene Chamber of Pharmacies defined procedures for Medicines Use Review (MUR) in Slovenia, together with an educational program and certification to ensure pharmacists' competency to perform MUR. The first 15 pharmacists were certified in June 2015 and implemented the service in their practices. Objective This study aimed to understand the implementation of MUR from the perspectives of the first community pharmacists providing the service in practice. Methods A focus group with first MUR providers took place in February 2016, 6 months after the first pharmacists were certified to provide MUR service...

INTRODUCTION AND HYPOTHESIS: Vaginal mesh surgery is subject of debate due to the impact of mesh-related complications on patient's lives. Not all of these complications are symptomatic. Restoration of the anatomy and improvement of pelvic floor function as a result may counter the experienced discomfort related to adverse events. We hypothesized that health-related quality of life (HR-QoL) is comparable in women after vaginal mesh surgery regardless of the presence or absence of a mesh-specific complication...

A major stripe rust resistance QTL on chromosome 4BL was localized to a 4.5-Mb interval using comparative QTL mapping methods and validated in 276 wheat genotypes by haplotype analysis. CYMMIT-derived wheat line P10103 was previously identified to have adult plant resistance (APR) to stripe rust in the greenhouse and field. The conventional approach for QTL mapping in common wheat is laborious. Here, we performed QTL detection of APR using a combination of genome-wide scanning and extreme pool-genotyping. SNP-based genetic maps were constructed using the Wheat55 K SNP array to genotype a recombinant inbred line (RIL) population derived from the cross Mingxian 169 × P10103...

BACKGROUND: Sleeve gastrectomy (LSG) is now the predominant bariatric surgery performed, yet there is limited long-term data comparing important outcomes between LSG and Roux-en-Y gastric bypass (RYGB). This study compares weight loss and impact on comorbidities of the two procedures. METHODS: We retrospectively evaluated weight, blood pressure, hemoglobin A1c, cholesterol, and medication use for hypertension, diabetes, and hyperlipidemia at 1-4 years post-operatively in 380 patients who underwent RYGB and 334 patients who underwent LSG at the University of Michigan from January 2008 to November 2013...

BACKGROUND: Abdominoplasty is a common procedure in postbariatric surgery. Over the years, a high number of technical refinements of the procedure have been established to improve safety and reduce associated complications. Nevertheless, the complication rate is high. The purpose of this study was to examine the incidence of postoperative complications in patients undergoing abdominoplasty in association with prolonged postoperative immobilization. METHODS: Retrospective analysis of 82 patients who underwent abdominoplasty was performed...

This study aimed to examine whether the characteristics of mental health and sleep duration, alone or in combination, are associated with menstrual cycle irregularity. This population-based, cross-sectional study analyzed the data from 4445 women aged 19-49 years, who participated in the Korea National Health and Nutrition Examination Survey 2010-2012. A structured questionnaire was used to assess mental health characteristics, sleep duration, and menstrual cycle irregularity. A multivariable logistic regression analysis was performed...

PURPOSE: Achieving adequate levels of physical activity (PA) and avoiding sedentary behaviour are particularly important in cancer survivors. eHealth, which includes, but is not limited to, the delivery of health information through Internet and mobile technologies, is an emerging concept in healthcare which may present opportunities to improve PA in cancer survivors. The aim of this systematic review was to explore the effects of eHealth in the promotion of PA among cancer survivors...

Abdominal exercise has been advocated to improve the protection of the spine and neuromuscular efficiency of the limb movements. The purpose of this study was to examine the effect of enhanced contraction of internal oblique and transversus abdominis (IO/TrA) on the activity level of the hip and posterior thigh muscles during therapeutic hip exercises. Twenty healthy females were required to perform eight hip exercises under two conditions, natural versus enhanced IO/TrA contraction conditions. Muscle activity of gluteus maximus, gluteus medius, tensor fasciae latae and biceps femoris of the exercising leg was measured by surface electromyography during hip exercises, and expressed in percentage normalized to the maximal voluntary isometric contraction (%MVIC)...

The detection of high-frequency spectral notches has been shown to be worse at 70-80 dB sound pressure level (SPL) than at higher levels up to 100 dB SPL. The performance improvement at levels higher than 70-80 dB SPL has been related to an 'ideal observer' comparison of population auditory nerve spike trains to stimuli with and without high-frequency spectral notches. Insofar as vertical localization partly relies on information provided by pinna-based high-frequency spectral notches, we hypothesized that localization would be worse at 70-80 dB SPL than at higher levels...

BACKGROUND: Flexible flatfoot (FFF) is a common alteration of the foot diagnosed in the pediatric population causing pain and decreased quality of life. Surgical treatment via arthroereisis of the subtalar joint can be recommended when non-invasive options do not result in sufficient pain relief. While clinical outcome of subtalar joint arthroereisis is generally positive, no functional evaluation has thus far been reported following surgery. RESEARCH QUESTION: The aim of this study was to assess the effects of two arthroereisis implants for the correction of bilateral FFF on foot and lower limb biomechanics during gait...

OBJECTIVE: This study aims to investigate the importance and types of peritumoral draining veins in parasagittal and falcine meningiomas, and administer corresponding protective strategies during surgery according to these different types, in order to improve tumor resection rate and maximize the protection of neurological functions. METHODS: The clinical information of 156 patients with parasagittal and falcine meningiomas, who were admitted at the Neurosurgery Department of our hospital, was collected and retrospectively analyzed...

STUDY OBJECTIVE: Studying postoperative in-hospital mortality is crucial to the understanding of the perioperative process failures and to the implementation of strategies to improve patient outcomes. We intend to classify the causes of perioperative deaths up to 30 days after procedures requiring anesthesia and to evaluate the risk factors for early (48 h) or late (30 day) mortality. DESIGN: Retrospective cohort study. SETTING: A quaternary University Hospital from South Brazil...

OBJECTIVES: The study evaluated whether lipoprotein apheresis produces immediate changes in resting perfusion in subjects with severe hypercholesterolemia, and whether there is a difference in the response between peripheral and coronary microcirculations. BACKGROUND: Lipoprotein apheresis is used in patients with severe hypercholesterolemia to reduce plasma levels of low-density lipoprotein cholesterol. METHODS: Quantitative contrast-enhanced ultrasound perfusion imaging of the myocardium at rest and skeletal muscle at rest and during calibrated contractile exercise was performed before and immediately after lipoprotein apheresis in 8 subjects with severe hypercholesterolemia, 7 of whom had a diagnosis of familial hypercholesterolemia...

OBJECTIVE: To compare the effects of 12 weeks of high-speed resistance training on functional performance and quality of life in elderly women when using either a traditional-set (TS) or a cluster-set (CS) configuration for inter-set rest. METHODS: Three groups of subjects were formed by block-design randomization as follows: (i) control group (CG, n = 17; age, 66.5 ± 5.4 years); (ii) 12-week high-speed resistance training group under a CS configuration (CSG, n = 15; age, 67...

BACKGROUND: Due to the low signal-to-noise-ratio (SNR) and unavoidable head motions, the pairwise subtraction perfusion signal extraction process in arterial spin labeling (ASL) perfusion MRI can produce extreme outliers. COMPARISON WITH EXISTING METHODS: We previously proposed an adaptive outlier cleaning (AOC) algorithm for ASL MRI. While it performed well even for clinical ASL data, two issues still exist. One is that if the reference is already dominated by noise, outlier cleaning using low correlation with the mean as a rejection criterion will actually reject the less noisy samples but keep the more noisy ones...

Successful execution of goal-directed behaviors often requires the deployment of cognitive control, which is thought to require cognitive effort. Recent theories have proposed that anterior cingulate cortex (ACC) regulates control levels by weighing the reward-related benefits of control against its effort-related costs. However, given that the sensations of cognitive effort and reward valuation are available only to introspection, this hypothesis is difficult to investigate empirically. We have proposed that two electrophysiological indices of ACC function, frontal midline theta and the reward positivity (RewP), provide objective measures of these functions...

BACKGROUND: Urethral cancer is rare, with limited data guiding treatment. A national hospital-based registry was used to evaluate the role of local therapy in these patients. METHODS: We performed a retrospective cohort study of patients with T0-4N0-2 M0 urethral cancer (2004-2013). Local therapy was: radiation (RT), surgery (S), or surgery and radiation (S+RT). The Cox proportional hazards model was used to assess the impact of therapy type on overall survival (primary endpoint)...

PURPOSE: Reformatting computed tomography (CT) scans along the scaphoid longitudinal axis improves the ability to detect scaphoid fractures compared with reformats along the wrist axis. However, it remains unclear whether scaphoid axis reformats affect measurements of displacement or deformity, which are factors that drive the clinical decision to perform open reduction internal fixation. Our null hypothesis was that reformatting CT scans along the scaphoid axis does not affect measurements of fracture displacement and deformity...

Control of independent digital flexion and extension has remained an elusive goal in myoelectric prosthetics for upper extremity amputees. We first performed a cadaver study to determine the feasibility of transferring the interossei muscles for each digit to the dorsum of the hand without damaging the neurovascular pedicles. Once this capability was ensured, a clinical case was performed transferring the interossei of the middle and ring fingers to the dorsum of the hand where they could serve as a myoelectric signal for a partial hand amputee to allow individual digital control with a myoelectric prosthesis...
