Aims: Eisenmenger syndrome (ES) is associated with considerable morbidity and mortality. Therapeutic strategies have changed during the 2000s in conjunction with an emphasis on specialist follow-up. The aim of this study was to determine the cause-specific mortality in ES and evaluate any relevant changes between 1977 and 2015. Methods and results: This is a retrospective, descriptive multicentre study. A total of 1546 patients (mean age 38.7 ± 15.4 years; 36% male) from 13 countries were included...

For the majority of patients with newly diagnosed follicular lymphoma (FL), current treatments, while not curative, allow for long remission durations. However, several important needs remain unaddressed. Studies have consistently shown that approximately 20% of patients with FL experience disease progression within 2 years of first-line treatment, and consequently have a 50% risk of death in 5 years. Better characterization of this group of patients at diagnosis may provide insight into those in need of alternate or intensive therapies, facilitate a precision approach to inform clinical trials, and allow for improved patient counseling...

Electroconvulsive therapy remains a key treatment option for severe cases of depression, but undesirable side-effects continue to limit its use. Innovations in the design of novel seizure therapies seek to improve its risk benefit ratio through enhanced control of the focality of stimulation. The design of seizure therapies with increased spatial precision is motivated by avoiding stimulation of deep brain structures implicated in memory retention, including the hippocampus. The development of two innovations in seizure therapy-individualized low-amplitude seizure therapy (iLAST) and magnetic seizure therapy (MST), are detailed...

Dynamic nuclear polarization (DNP) can enhance NMR sensitivity by orders of magnitude by transferring spin polarization from electron paramagnetic resonance (EPR) to NMR. However, paramagnetic DNP polarizing agents can have deleterious effects on NMR signals. Electron spin decoupling can mitigate these paramagnetic relaxation effects. We demonstrate electron decoupling experiments in conjunction with DNP and magic angle spinning (MAS) NMR spectroscopy. Following a DNP and spin diffusion period, the microwave irradiation frequency is quickly tuned on-resonance with electrons on the DNP polarizing agent...

Despite the withdrawal of CB1 antagonists, such as rimonabant, from the market and from active clinical development because of concerns about their side effect profiles, research suggests that the endocannabinoid system may play an important role in modulating nicotine's effects. We report the combined results, using a pooled analysis, of three previously unpublished trials assessing rimonabant as a smoking cessation pharmacotherapy conducted between 2002 and 2004. Smokers (n = 2097) motivated to quit were enrolled in three randomized, double-blind, placebo-controlled trials, STRATUS EU, US, and META, which consisted of a 10-week treatment period with either rimonabant 20 mg (n = 789), 5 mg (n = 518; used in only two of the three studies), or placebo (n = 790), in conjunction with brief counseling...

Renal osteodystrophy (ROD) refers to alterations in bone turnover, mineralisation, mass and microarchitecture in patients with chronic kidney disease (CKD) and represents the skeletal component of 'CKD-mineral and bone disorder'. Changes in bone structure lead to impaired bone quality, compromised bone strength and increased susceptibility to fractures with associated significant morbidity, mortality and financial cost. Diagnosis and management of ROD is hindered by the inadequacy of currently available diagnostic methods to interpret the complex pathophysiology...

Here, we report on the prevalence of allergic conjunctivitis and positive skin prick test (SPT) results in relation to respiratory allergic conditions among patients with symptoms of allergies at a respiratory outpatient clinic. A questionnaire survey of symptoms (i.e., asthma-like, rhinitis, and conjunctivitis symptoms) involving 1522 patients was carried out. The responses of 1242 patients indicated that they had allergic conjunctivitis, asthma, rhinitis, or a combination of these conditions, and 869 of these patients underwent SPTs that assessed responses to 40 allergens...

Considerable advances in cancer-specific optical imaging have improved the precision of tumor resection. In comparison to traditional imaging modalities, this technology is unique in its ability to provide real-time feedback to the operating surgeon. Given the significant clinical implications of optical imaging, there is an urgent need to standardize surgical navigation tools and contrast agents to facilitate swift regulatory approval. Because fluorescence-enhanced surgery requires a combination of both device and drug, each may be developed in conjunction, or separately, which are important considerations in the approval process...

An understanding of the new generation of MS drugs in conjunction with the key role MR imaging plays in the detection of disease progression, opportunistic infections, and drug-related adverse effects is of vital importance to the neuroradiologist. Part 1 of this review outlined the current treatment options available for MS and examined the mechanisms of action of the various medications. It also covered specific complications associated with each form of therapy. Part 2, in turn deals with the subject of pharmacovigilance and the optimal frequency of MRI monitoring for each individual patient, depending on his or her unique risk profile...

BACKGROUND AND PURPOSE: Assessing the response to treatment in infiltrative brain tumors by using lesion volume-based response criteria is challenging. We hypothesized that in such tumors, volume measurements alone may not accurately capture changes in actual tumor burden during treatment. We longitudinally evaluated volume changes in both normal-appearing supratentorial white matter and the brain stem lesions in patients treated for diffuse intrinsic pontine glioma to determine to what extent adjuvant systemic therapies may skew the accuracy of tumor response assessments based on volumetric analysis...

BACKGROUND: There has been remarkable growth in research examining physical activity behavior (any bodily movement produced by skeletal muscle contraction that results in energy expenditure) among people living with multiple sclerosis (MS) over the past decade. The current meta-analysis quantified physical activity participation levels in persons with MS compared with non-diseased and other clinical populations. METHODS: We searched PUBMED, PsycINFO and Web of Science using the keywords physical activity, exercise, and physical fitness in conjunction with MS...

BACKGROUND: Gaucher disease (GD) is an autosomal recessive lysosomal storage disorder caused by deficiency in acid beta-glucosidase. GD exhibits a wide clinical spectrum of disease severity with an unpredictable natural course. Plasma chitotriosidase activity and CC chemokine ligand 18 (CCL18) have been exchangeably used for monitoring GD activity and response to enzyme replacement therapy in conjunction with clinical assessment. Yet, a large-scale head-to-head comparison of these two biomarkers is currently lacking...

BACKGROUND: A strategy of limited preoperative fasting, with carbohydrate (CHO) loading and intraoperative infusion of omega-3 polyunsaturated fatty acids (ω-3 PUFA), has seldom been tried in cardiovascular surgery. Brief fasting, followed by CHO intake 2 h before anesthesia, may improve recovery from CABG procedures and lower perioperative vasoactive drug requirements. Infusion of ω-3 PUFA may reduce occurrences of postoperative atrial fibrillation (POAF) and shorten hospital stays...

Laser microprocessing of highly oriented pyrolytic graphite (HOPG) in conjunction with chemical functionalization routines are used to fabricate functional micro-sized domains. Infrared and Auger electron spectroscopy, contact angle measurements and electron microscopy are used for characterization of laser-fabricated structures. HOPG samples are coated with alkylsiloxane monolayers. Laser-induced bromination of coated HOPG samples in gaseous bromine is carried out using a microfocused laser beam at a wavelength of 514 nm and 1/e2 laser spot diameter of about 3 µm...

Anti-VEGF therapy has been proven to be effective in the treatment of pathological angiogenesis. However, therapy resistance often occurs, leading to development of alternative approaches. The present study examines if AMPK negatively regulates ALK1-mediated signaling events and associated angiogenesis. Thus, we treated human umbilical vein endothelial cells with metformin as well as other pharmacological AMPK activators and showed that activation of AMPK inhibited Smad1/5 phosphorylation and tube formation induced by BMP9...

High-throughput in vitro methods have been extensively applied to identify linear information that encodes peptide recognition. However, these methods are limited in number of peptides, sequence variation, and length of peptides that can be explored, and often produce solutions that are not found in the cell. Despite the large number of methods developed to attempt addressing these issues, the exhaustive search of linear information encoding protein-peptide recognition has been so far physically unfeasible...

BACKGROUND: Older adults represent a growing proportion of trauma patients treated in the United States, and cervical spine (c-spine) fracture is an injury that is increasingly common in this population. Neck pain is a major component of current clinical clearance guidelines, but some older adults with c-spine fractures report no neck pain after injury. The objective of this study was to investigate the frequency at which c-spine fractures were unassociated with neck pain in an aging population...

This functional magnetic resonance imaging (fMRI) study addressed similarities and differences in behavioral and neural responses to experimental visceral compared to somatic pain stimuli and explored the contribution of fear of pain to differences between pain modalities. In N=22 healthy women, blood oxygen level-dependent (BOLD) responses to rectal distensions and cutaneous heat stimuli matched for perceived pain intensity. Fear of pain and pain unpleasantness were assessed before and after scanning. Visceral pain was more fear-evoking, more unpleasant, and trial-by-trial intensity ratings failed to habituate across trials (all interactions modality X time/trial: p<...

It is well established that helper T cell responses influence resistance or susceptibility to Mycobacterium leprae infection, but the role of more recently described helper T cell subsets in determining severity is less clear. To investigate the involvement of Th17 cells in the pathogenesis of leprosy, we determined the immune profile with variant presentations of leprosy. Firstly, IL-17A, IFN-γ and IL-10 were evaluated in conjunction with CD4(+) T cell staining by confocal microscopy of lesion biopsies from tuberculoid (TT) and lepromatous (LL) patients...
