BACKGROUND: Admission with heart failure (HF) is a milestone in the progression of the disease, often resulting in higher intensity medical care and ensuing readmissions. Whilst there is evidence supporting enrolling patients in a heart failure disease management program (HF-DMP), not all reported HF-DMPs have systematically enrolled patients with HF with preserved ejection fraction (HFpEF) and there is a scarcity of literature differentiating costs based on HF-phenotype. METHODS: 1292 consenting, consecutive patients admitted with a primary diagnosis of HF were enrolled in a hospital based HF-DMP and categorized as HFpEF (EF≥45%) or HFrEF (EF<45%)...

OBJECTIVE: Bioengineering of viable, functional, and implantable human lung grafts on porcine matrix. SUMMARY BACKGROUND DATA: Implantable bioartificial organ grafts could revolutionize transplant surgery. To date, several milestones toward that goal have been achieved in rodent models. To make bioengineered organ grafts clinically relevant, scaling to human cells and graft size are the next steps. METHODS: We seeded porcine decellularized lung scaffolds with human airway epithelial progenitor cells derived from rejected donor lungs, and banked human umbilical vein endothelial cells...

At this time last year, 2015, our field achieved a milestone in the management of rickets and osteomalacia. Among the disorders that feature generalized impairment of hard tissue mineralization and its consequences, the final entity lacking a medical treatment acquired one sanctioned internationally by regulatory agencies. The holdout was hypophosphatasia (HPP), the inborn-error-of-metabolism identified in 1948 and caused by loss-of-function mutation(s) of the TNSALP (ALPL) gene that encodes the "tissue-nonspecific" isoenzyme of alkaline phosphatase (TNSALP)...

The past few decades have seen a number of medical breakthroughs that enabled the effective treatment of a range of conditions, transforming them from fatal into manageable ones. Examples include certain cancers and HIV. Conversely, progress on dementia has been limited. There are currently no treatments that will cure or even alter the progressive course of dementia, despite ongoing research investigating new therapies and care options. The UK Department of Health is interested in the potential to learn from other disease areas to better understand the particular social, economic, political, legislative and scientific contexts that have contributed to accelerating progress and breakthroughs in treatment...

Proton pump inhibitors (PPIs) represent a milestone in the treatment of acid-related diseases, and are the mainstay in preventing upper gastrointestinal bleeding in high-risk patients treated with nonsteroidal anti-inflammatory drugs (NSAIDs) or low-dose aspirin. However, this beneficial effect does not extend to the lower gastrointestinal tract. PPIs do not prevent NSAID or aspirin-associated lower gastrointestinal bleeding (LGB). PPIs may increase both small bowel injury related to NSAIDs and low-dose aspirin treatment and the risk of LGB...

In previous works, it was shown that S-layer proteins from Lactobacillus kefir were able to recrystallize and stabilize liposomes, this feature reveling a great potential for developing liposomal-based carriers. Despite previous studies on this subject are important milestones, a number of questions remain unanswered; In this context, the feasibility of S-layer proteins as a biomaterial for drug delivery was evaluated in this work. First, S-layer proteins were fully characterized by Electron microscopy, 2D-electrophoresis, and HPAEC-PAD...

OBJECTIVE: To assess whether the age at which multiple sclerosis (MS) patients reach Expanded Disability Status Scale (EDSS) milestones changed as long as new drugs for the treatment of MS became available. METHODS: We evaluated the long-term impact of therapies on disability progression assessing whether there is a detectable delay in the age at which patients reached EDSS milestones in more recent years. We used data collected over more than 30 years in the Center of Brescia, Italy...

Recent work in the growing field of soft robotics has demonstrated a number of very promising technologies. However, to make a significant impact in real-world applications, these new technologies must first transition out of the laboratory through successful commercialization. Commercialization is perhaps the most critical future milestone facing the field of soft robotics today, and this process will reveal whether the apparent impact we now perceive has been appropriately estimated. Since 2012, Empire Robotics has been one of the first companies to attempt to reach this milestone through our efforts to commercialize jamming-based robotic gripper technology in a product called VERSABALL(®)...

BACKGROUND: Trying to simultaneously achieve developmental milestones and cope with a life-threatening disease may place adolescents and young adults (AYAs) at risk for impaired health-related quality of life (HRQoL) later in life. The aim of this study was to examine differences in HRQoL between AYA lymphoma survivors and a normative population and to determine sociodemographic, clinical and long-term symptom-related factors associated with HRQoL. MATERIAL AND METHODS: This study was part of a longitudinal, population-based survey among lymphoma survivors diagnosed between 1999 and 2012...

We reviewed 216 consecutive patients with MDS and abnormal karyotype treated with hypomethylating agents between 4/04 and 10/12. Median follow-up was 17 months. Using IWG criteria, best responses were complete response (CR) in 79 patients (37%), partial response (PR) in 4 (2%), and hematologic improvement (HI) in 10 (5%). Cytogenetic response (CyR) was achieved in 78 patients (36%): complete (CCyR) in 62 (29%) and partial in 16 (7%). CyR was achieved in 48 of 79 patients (61%) with CR, 1 of 14 (7%) with PR/HI, and in 29 of the 123 (24%) with no morphologic response...

BACKGROUND: A change of loading conditions in the knee causes changes in the subchondral bone and may be a cause of osteoarthritis (OA). However, quantification of trabecular architecture in vivo is difficult due to the limiting spatial resolution of the imaging equipment; one approach is the use of texture parameters. In previous studies, we have used digital models to simulate changes of subchondral bone architecture under OA progression. One major result was that, using computed tomography (CT) images, subchondral bone mineral density (BMD) in combination with anisotropy and global homogeneity could characterize this progression...

The Corticotropin-releasing Hormone (CRH) mammalian family members include CRH, urocortin I, Stresscopin (SCP) and Stresscopin-related peptide (SRP), along with the CRH receptors type 1 (CRHR1) and type 2 (CRHR2), and CRH-binding protein (CRH-BP). These family members differ in their tissue distribution and pharmacology. Several studies have provided evidence supporting an important role of this family in the regulation of the neuroendocrine and behavioral responses to stress. Regulation of the relative contribution of CRH and its homologs and the two CRH receptors in brain CRH pathways may be essential in coordinating physiologic responses to stress...

It is almost a quarter of century that a pioneering work of 2 researchers named Brugada brought the entire scientific community to understanding the molecular, clinical, and electrophysiological aspects of a distinctive syndrome. It affects mainly young adults with syncope and/or sudden cardiac death caused by polymorphic ventricular tachycardia or ventricular fibrillation in the absence of any sign of cardiac degeneration or alteration. Although the involvement of the epicardial layer of the right ventricular outflow tract, and the requirement of pharmacologic challenge for unveiling concealed forms, have been fully characterized, many areas of uncertainties remain to be elucidated, such as the unpredictable usefulness of programmed ventricular stimulation, the role of radiofrequency catheter ablation for reducing ST-segment elevation, and the value of risk stratification in patients diagnosed with upper displacement of right precordial leads...

The 35th Annual Society of Toxicologic Pathology Symposium, held in June 2016 in San Diego, California, focused on "The Basis and Relevance of Variation in Toxicologic Responses." In order to review the basic tenants of toxicology, a "broad brush" interactive talk that gave an overview of the Cornerstones of Toxicology was presented. The presentation focused on the historical milestones and perspectives of toxicology and through many scientific graphs, data, and real-life examples covered the three basic principles of toxicology that can be summarized, as dose matters (as does timing), people differ, and things change (related to metabolism and biotransformation)...

: Reading is one of the most important academic abilities that establishes the foundation for a child's success in school. Therefore, early and accurate diagnosis of reading challenges is crucial for prevention of later academic failure. One challenge in early detection of reading difficulties is that the ability to read typically is acquired explicitly when a child is 4-6 years of age. However, reading ability relies on development of more basic abilities prior to reading acquisition, starting from birth...

BACKGROUND: The definition and the clinical implications of myocardial infarction (MI) occurring in the setting of percutaneous coronary intervention have been subjects of unresolved controversy. As a result of the use of more sensitive diagnostic tools such as cardiac troponin, the expanding evidence, and the ensuing debate, the definition of procedural MI (pMI) has evolved, leading to several revisions, different proposed definitions, and lack of standardization in randomized clinical trials...
