Purpose: This study assessed the outcomes of ultrasound (US)-guided core needle biopsies (CNBs) of breast lesions with at least 2 years of follow-up to determine the false-negative rate and to evaluate the diagnostic accuracy of CNB. Methods: We retrospectively analyzed 13,254 consecutive US-guided 14-gauge CNBs for breast lesions. We excluded biopsies if non-malignant biopsy result was not confirmed by surgical excision or US-guided vacuum-assisted biopsy, or fewer than 2 years of follow-up data were available...

INTRODUCTION: Important developments in the diagnosis of scuba diving fatalities have been made thanks to forensic imaging tool improvements. Multi-detector computed tomography (MDCT) permits reliable interpretation of the overall gaseous distribution in the cadaver. However, due to post-mortem delay, the radiological interpretation is often doubtful because the distinction between gas related to the dive and post-mortem decomposition artifactual gases becomes less obvious. METHODS: We present six cases of fatal scuba diving showing gas in the heart and other vasculature...

Liying Zhu, Zhengrong Xiang
This paper addresses the aggregation issues of competitive multiagent systems (CMASs) consisting of competitive agents with multimodes and saddle points. In such CMASs, due to existing mutual competitions, every agent is equipped with finite multimodes, and every mode in any agent is described as a second-order linear time-invariant (LTI) control system. When the origin is the same saddle point of all modes of agents, to investigate aggregation of the CMASs with switching strategies, we first use switched LTI systems with saddle points to formulate such CMASs...

Liang et al. (2017) demonstrate how neuropeptides from two groups of clock cells appear to be responsible for the fly's circadian neurons becoming active at different times of day. By delaying the activity of their clock cell targets, they give rise to morning and evening behavior.

There are many tests of learning and memory; however, not all yield analogous results and thus are not interchangeable. This study examined the relationship between the California Verbal Learning Test-Second Edition (CVLT-II) and the Buschke Selective Reminding Test (SRT) in a stroke population. Data from stroke inpatients (N = 102) referred for rehabilitation were collected from medical records. Both tests were administered, as part of a larger neuropsychological assessment. Analyses were conducted on Z-scores from the List Total, Learning, and Long Delay Free Recall (LDFR) subscales of the two tests...

OBJECTIVE: The past decades have seen a surge in stimulant prescriptions for the treatment of attention-deficit/hyperactivity disorder (ADHD). Stimulants acutely alleviate symptoms and cognitive deficits associated with ADHD by modulating striatal dopamine neurotransmission and induce therapeutic changes in brain activation patterns. Long-term functional changes after treatment are unknown, as long-term studies are scarce and have focused on brain structure. In this observational study (2009-2012), we investigated associations between lifetime stimulant treatment history and neural activity during reward processing...

BACKGROUND: It has well known that, compared to normal cells, tumor cells have a different manner of energy metabolism, which influences the sensitivity of radiotherapy (RT). However, whether inhibition of glycolysis enhances the efficacy of radiotherapy is a matter of debate in oral squamous cell carcinoma (OSCC). The aim of this study was to characterize whether the combination of radiotherapy with the glucose inhibitor 2-deoxy-D-glucose (2-DG) affected DNA repair kinetics. METHODS: To compare the synergistic effect of 2-DG, we examined the cell survival after treatment with radiation, 2-DG and a combination of the two in 5 OSCC cell lines and one lip fibroblast cell line, determined using clonogenic survival assay...

The tumor microenvironment provides a niche in which cancer cells and their surrounding stromal cells reside and in which their interactions occur. The cross talk between cancer and stromal cells in the tumor microenvironment promotes many biological processes to support cancer cell growth, invasion, angiogenesis, and metastasis. Recently, not only cancer cells but also multiple types of surrounding stromal cells, including endothelial cells, immune cells, and fibroblasts in the tumor microenvironment, have been recognized to be attractive targets for reducing resistance to anticancer therapy and tumor recurrence...

BACKGROUND: Amyotrophic Lateral Sclerosis (ALS) is a devastating neurological condition that requires coordinated, multidisciplinary clinical management. ALS is prone to misdiagnosis as its signs and symptoms may be non-specific, which may prolong patients' journey to multidisciplinary ALS care. METHODS: Using chart review and national register data, we have detailed the journey of a national cohort of ALS patients (n = 155) from the time of first symptom to presentation at a multidisciplinary clinic (MDC)...

INTRODUCTION: Poor recall during investigations of foodborne outbreaks may lead to misclassifications in exposure ascertainment. We conducted a simulation study to assess the frequency and determinants of recall errors. METHODS: Lunch visitors in a cafeteria using exclusively cashless payment reported their consumption of 13 food servings available daily in the three preceding weeks using a self-administered paper-questionnaire. We validated this information using electronic payment information...

BACKGROUND: Mortality of hemorrhagic shock primarily depends on whether or not the patients can endure the loss of circulating volume until radical treatment is applied. We investigated whether hydrogen (H2) gas inhalation would influence the tolerance to hemorrhagic shock and improve survival. METHODS: Hemorrhagic shock was achieved by withdrawing blood until the mean arterial blood pressure reached 30-35 mmHg. After 60 minutes of shock, the rats were resuscitated with a volume of normal saline equal to four times the volume of shed blood...

Non-healing wounds are a significant burden to healthcare systems, where it is estimated that 4-5% of the adult population has a problem wound at any one time ( Guest et al, 2017 ). It is suggested that infection is the most frequent complication in non-healing wounds where it can prolong patient treatment times and increase resource use ( Gottrup et al, 2013 ). Wound infection develops as a result of an imbalance between the patient's immune system and the conditions in the wound, which subsequently can promote bacterial proliferation ( Wounds UK, 2013 )...

Stroke patients with dysphagia often depend on nutrition, hydration and medication via nasogastric (NG) feeding tubes. Securing tubes using tape is associated with repeated tube loss. In this study, the authors determined cause and effect by auditing tube placement methods, delays incurred, duration and costs. Of 202 NG tube placements in 75 patients, 67 placements occurred in 17 patients over a full course of enteral nutrition (EN) and 40 of these placements were tracked. Tubes were secured by tape in 100%, mittens 31% and special observation 5...

Introduction: This study examines patterns of change in different smoker subgroups' responses to new pictorial health warning labels (HWLs) over the initial, two year post-implementation period in Canada, where HWLs include package inserts with cessation messages, and Australia, where "plain" packaging (i.e., prohibition of brand imagery) was also implemented. Methods: Data were collected from online consumer panels in Canada (nsmokers=3,153; nobservations=5,826) and Australia (nsmokers=2,699; nobservations=5,818) from September 2012 to September 2014, with approximately 1,000 adult smokers surveyed in each country every four months, using replenishment to maintain sample size...

T3 is an important regulator of skeletal development and adult bone maintenance. Thyroid hormone action requires efficient transport of T4 and T3 into target cells. We hypothesized that monocarboxylate transporter-8, encoded by Mct8 on the X-chromosome, is an essential thyroid hormone transporter in bone. To test this hypothesis, we determined the juvenile and adult skeletal phenotypes of male Mct8 knockout mice (Mct8KO) and Mct8D1D2KO compound mutants, which additionally lack the ability to convert the prohormone T4 to the active hormone T3...

Bispecific antibody targeting of two different antigens is promising, but when fragment-based antibodies are used, homogeneous production is difficult. To overcome this difficulty, we developed a method using the SpyTag/SpyCatcher system in which a covalent bond is formed between the two polypeptides. Using this method, we constructed a bispecific antibody that simultaneously interacted with two different epitopes of ROBO1, a membrane protein associated with cancer progression. A bispecific tetravalent antibody with an additional functional moiety was also constructed by using a dimeric biotin-binding protein...

OBJECTIVES: Haemodynamically stable patients admitted for coronary artery bypass grafting in acute myocardial infarction often undergo delayed surgery in order to avoid the risks of emergency surgery. However, initially stable patients undergoing delayed surgery may develop low cardiac output syndrome (LCOS) during the waiting period, which might be a major drawback of this strategy. We aim to define risk factors and clinical consequences of LCOS during the waiting period. METHODS: A total of 530 consecutive patients with acute myocardial infarction (33% non-ST-segment elevation myocardial infarction and 67% ST-segment-elevation myocardial infarction) underwent isolated coronary artery bypass grafting between 2008 and 2013...
