INTRODUCTION: Lung transplantation (LT) is the standard of care for patients with advanced lung diseases, including lymphangioleiomyomatosis (LAM). LAM accounts for only 1% of all LTs performed in the international registry. As a result, the global experience, including the use of mechanistic target of rapamycin (mTOR) inhibitors before and after LT in LAM, is still limited. METHODS: We conducted a retrospective review of all LAM patients who underwent LT at our centre between 2003 and 2016...

BACKGROUND CONTEXT: Pelvic Incidence (PI) = Pelvic Tilt (PT) + Sacral Slope (SS) is an established trigonometric equation which can be expanded from studying the fixed pelvis with the spine to a fixed spinopelvic complex with the remnant spine, in scenarios of spinopelvic fusion or ankylosis. For a fixed spinopelvic complex, we propose the equation termed: Lumbar Incidence (LI) = Lumbar Tilt (LT) + Lumbar Slope (LS). PURPOSE: To establish reference values for LI, LT and LS at each lumbar vertebral level, and to show how LI can be used to determine rLL...

A fast and high-throughput method is proposed for the determination of total microcystins (ΣMC) in environmental surface waters. After a 1-h Lemieux-von Rudloff oxidation step to yield the 2-methyl-3-methoxy-4-phenylbutyric acid (MMPB) moiety, samples were quenched, filtered, and directly analyzed. This was achieved via solid phase extraction (SPE) coupled on-line to ultra-high performance liquid chromatography electrospray ionization triple stage quadrupole mass spectrometry. The choice of on-line SPE settings was conducted using experimental designs...

Kawasaki disease (KD) is a kind of pediatric vasculitis of unknown etiology which mainly affects the development of coronary artery aneurysms. Few studies have explored the potential environmental risk factors on KD incidence. We performed a time-series analysis to investigate the associations between air pollution and temperature and KD in Shanghai, China. We collected daily-hospitalized KD patients that were admitted in major pediatric specialty hospitals located in the urban areas of Shanghai from 2001 to 2010...

PURPOSE: Calcitonin is the most sensitive tumor marker of medullary thyroid carcinoma (MTC) and a calcium stimulation test is used to improve this sensitivity. In Japan, the electrochemiluminescence immunoassay (ECLIA) is currently the only test performed to measure serum calcitonin. There is a gender difference in the reference value of serum calcitonin; however, a reference upper limit for use with ECLIA has been reported only for women, but not for men. METHODS: We conducted the calcium stimulation test using ECLIA in 21 men with non-medullary thyroid carcinoma (non-MTC), before and after total thyroidectomy...

REVIEW
Ann I Scher, Paul B Rizzoli, Elizabeth W Loder
It is a widely accepted idea that medications taken to relieve acute headache pain can paradoxically worsen headache if used too often. This type of secondary headache is referred to as medication overuse headache (MOH); previously used terms include rebound headache and drug-induced headache. In the absence of consensus about the duration of use, amount, and type of medication needed to cause MOH, the default position is conservative. A common recommendation is to limit treatment to no more than 10 or 15 days per month (depending on medication type) to prevent headache frequency progression...

Background Brace treatment for adolescent idiopathic scoliosis (AIS) is generally prescribed for 18 - 23 hours per day, but the minimal time of brace wear per day to stop progression of AIS is still unclear. Compliance of AIS patients with brace treatment is reported to be between 27% and 47% of the prescribed time, especially brace wear at school is often described as embarrassing by the adolescent patients. It has been reported that a higher rate of compliance leads to a significantly lower rate of curve progression...

BACKGROUND: Chronic thromboembolic pulmonary hypertension (CTEPH) is still largely underdiagnosed in the general population. Although transthoracic echocardiogram (TTE) is recommended to screen for CTEPH, it may not detect patients with chronic thromboembolic disease (CTED) and mild or exercise-induced pulmonary hypertension (PH) who could also benefit from pulmonary endarterectomy (PEA). METHODS: All patients referred to our CTEPH program with persistent mismatched perfusion defects on ventilation-perfusion (VQ) scan between January 2005 and June 2015 were divided into three groups according to TTE and right heart catheterization (RHC) as follows: (1) typical CTEPH group (PH on RHC and TTE), (2) TTE-negative (neg) CTEPH group (PH on RHC, but not TTE), or (3) CTED group (no PH on RHC and TTE)...

BACKGROUND: There is robust clinical evidence to support offering early access to antiretroviral treatment (ART) to all HIV-positive individuals, irrespective of disease stage, to both improve patient health outcomes and reduce HIV incidence. However, as the global treatment guidelines shift to meet this evidence, it is still largely unknown if early access to ART for all (also referred to as "treatment as prevention" or "universal test and treat") is a feasible intervention in the resource-limited countries where this approach could have the biggest impact on the course of the HIV epidemics...

The de novo assembly of the red fox (Vulpes vulpes) genome has facilitated the development of genomic tools for the species. Efforts to identify the population history of red foxes in North America have previously been limited by a lack of information about the red fox Y-chromosome sequence. However, a megabase of red fox Y-chromosome sequence was recently identified over 2 scaffolds in the reference genome. Here, these scaffolds were scanned for repeated motifs, revealing 194 likely microsatellites. Twenty-three of these loci were selected for primer development and, after testing, produced a panel of 11 novel markers that were analyzed alongside 2 markers previously developed for the red fox from dog Y-chromosome sequence...

Because of the absence of the time course of histological nonalcoholic fatty hepatitis with subsequent fibrotic progression, the effective approaches available for controlling the onset and progression of non-alcoholic steatohepatitis (NASH) remain limited. Therefore, we detected the serum and liver tissue related lipid metabolism disorder, liver pathology and relative molecular makers alteration dynamically in a high fat-sucrose diet during different time points. High fat-sucrose diet significantly increased the serum lipid level on day 10...

During recent decades, strain gauge-based joint torque sensors have been commonly used to provide high-fidelity torque measurements in robotics. Although measurement of joint torque/force is often required in engineering research and development, the gluing and wiring of strain gauges used as torque sensors pose difficulties during integration within the restricted space available in small joints. The problem is compounded by the need for a scalable geometric design to measure joint torque. In this communication, we describe a novel design of a strain gauge-based mono-axial torque sensor referred to as square-cut torque sensor (SCTS), the significant features of which are high degree of linearity, symmetry, and high scalability in terms of both size and measuring range...

Background: Research findings suggest that attitudes towards psychotherapy predict willingness to seek therapy. However, understanding how medical students think about using and referring their patients for psychotherapy is limited. Aims: The aims of this study are to measure medical students' attitudes towards professional help seeking, and to investigate the reasons for whether or not they would refer their patients to psychotherapy in their future role as doctors. Method: The participants were 127 medical students in their first and second year of the MBBS4 programme at the Cyprus campus of St George's University of London, who completed a self-report measure of attitudes towards psychotherapy and a semi-structured interview...

During the 1980s the HIV/AIDS epidemic outbreak occurred. Due to the high prevalence of the disease on men who had sex with men (MSM) a lifetime ban on blood donations on men who had sex with men (MSM) was implemented. In the recent years, organizations like the European Union (EU) and the World Health Organization (WHO) have established new guidelines introducing the term of "risky sexual behavior" without any reference to the sex orientation of the potential donor, however many countries are hesitant to review the ban on men who had sex with men (MSM)...

CEMIP (KIAA1199) was identified as migratory indicator protein which had been crudely studied in the last decade. Firstly its mutation site was reported to cause hearing loss due to the folding change of protein structure, meanwhile the over-expression of CEMIP referred to dreadful invasion and uncontrolled proliferation of tumor with distant metastasis, dedifferentiation, and limited survival opportunity of patients. Especially, over-expressed CEMIP also protected malignant tumor from strict microenvironment in hypoxia, low glucose and cracked barrier, leading to enhanced adaptability of tumor by stimulating the Wnt, EGFR, FGFR pathway...

In 1952, Hildegard Peplau published her textbook Interpersonal Relations in Nursing: A Conceptual Frame of Reference for Psychodynamic Nursing. This was the same year the American Psychiatric Association (APA) published the first edition of the Diagnostic and Statistical Manual of Mental Disorders (1st ed.; DSM-I; APA). These events occurred in the context of a rapidly changing policy and practice environment in the United States after World War II, where the passing of the National Mental Health Act in 1946 released vast amounts of funding for the establishment of the National Institute of Mental Health and the development of advanced educational programs for the mental health professions including nursing...
