The antimicrobial triclocarban (TCC) is frequently found in various personal care products (PCPs), and recent studies have demonstrated that it shows a high unintended biological activity on humans and wildlife. To evaluate the toxicity of TCC at the protein level, the effect of TCC on bovine serum albumin (BSA) has been investigated using various spectroscopic methods in combination with molecular modeling. Analysis of fluorescence quenching data of BSA revealed the formation of a ground state BSA-TCC complex with a binding constant of 2...

Streaking artifacts in computed tomography (CT) scans caused by metallic dental implants (MDIs) can lead to inaccuracies in dose calculations. This study quantifies and compares the effect of MDIs on dose distributions using the collapsed cone convolution superposition (CCCS) and Monte Carlo (MC) algorithms, with and without correcting for the density of the MDIs. Ion chamber measurements were taken to test the ability of the algorithms in Pinnacle3 and Monaco to calculate dose near high-Z materials. Nine previously treated patients with head and neck cancer were included in this study...

PROBLEM: Mindfulness training includes mindfulness meditation, which has been shown to improve both attention and self-awareness. Medical providers in the intensive care unit often deal with difficult situations with strong emotions, life-and-death decisions, and both interpersonal and interprofessional conflicts. The effect of mindfulness meditation training on healthcare providers during acute care tasks such as cardiopulmonary resuscitation remains unknown. Mindfulness meditation has the potential to improve provider well-being and reduce stress in individuals involved in resuscitation teams, which could then translate into better team communication and delivery of care under stress...

BACKGROUND: Familial Mediterranean fever is an autosomal recessive disorder characterized by periodic febrile attacks of aseptic serositis and/or arthritis. The main treatment is colchicine which prevents attacks in the majority of patients except for a group of colchicine-resistant cases. Chronic hepatitis C is a viral infection causing chronic inflammation of liver tissue (hepatitis) which ultimately progresses to fibrosis and liver cirrhosis with a high chance of hepatocellular carcinoma...

Long non-coding RNAs (lncRNAs) have been widely reported in various cancers due to their special molecular mechanisms. LncRNA SOX21-AS1 has been discovered to be a tumor facilitator in several types of human cancers. However, the expression pattern, clinical value and biological effects in hepatocellular carcinoma (HCC) are still unknown. In this study, we detected the high expression level of SOX21-AS1 in tumor tissues and cell lines through performing qRT-PCR analysis. The prognostic value of SOX21-AS1 was identified...

INTRODUCTION: Training in high-value, cost-conscious care (HVCCC) is increasingly being incorporated into medical school curricula, but students may have limited opportunities to engage patients in HVCCC conversations. The aim of this study was to develop two standardized patient scenarios with associated checklists, hypothesizing that resulting scores would allow for valid formative assessments of HVCCC communication skills. METHODS: Scenarios were designed to generate a less-is-more conversation (in response to a patient requesting an unnecessary test) and a shared decision-making conversation (in response to a patient choosing between multiple effective treatment options)...

Measuring the value of medical imaging is challenging, in part, due to the lack of conceptual frameworks underlying potential mechanisms where value may be assessed. To address this gap, this article proposes a framework that builds on the large body of literature on quality of hospital care and the classic structure-process-outcome paradigm. The framework was also informed by the literature on adoption of technological innovations and introduces 2 distinct though related aspects of imaging technology not previously addressed specifically in the literature on quality of hospital care: adoption (a structural hospital characteristic) and use (an attribute of the process of care)...

Inflammatory breast cancer (IBC) is a rare and aggressive presentation of invasive breast cancer with a 62% to 68% 5-year survival rate. It is the most lethal form of breast cancer, and early recognition and treatment is important for patient survival. Like non-inflammatory breast cancer, IBC comprises multiple subtypes, with the triple-negative subtype being overrepresented. Although the current multimodality treatment regime of anthracycline- and taxane-based neoadjuvant therapy, surgery, and radiotherapy has improved the outcome of patients with triple-negative IBC, overall survival continues to be worse than in patients with non-inflammatory locally advanced breast cancer...

Background: Older people are at risk of micronutrient deficiencies, which can be under- or overestimated in the presence of inflammation. Several methods have been proposed to adjust for the effect of inflammation; however, to our knowledge, none have been investigated in older adults in whom chronic inflammation is common. Objective: We investigated the influence of various inflammation-adjustment methods on micronutrient biomarkers associated with anemia in older people living in aged-care facilities in New Zealand...
