Patients with myelofibrosis at intermediate-1 risk according to the International Prognostic Score System are projected to a relatively long survival; nonetheless, they may carry significant splenomegaly and/or systemic constitutional symptoms that hamper quality of life and require treatment. Since registrative COMFORT studies included only patients at intermediate-2/high International Prognostic Score System risk, safety and efficacy data in intermediate-1 patients are limited. We report on 70 intermediate-1 patients treated with ruxolitinib according to standard clinical practice that were evaluated for response using the 2013 IWG-MRT criteria...

An accurate histological diagnosis may distinguish essential thrombocythaemia (ET) from early primary myelofibrosis (early-PMF), which is associated with worse outcome. Outcome of ET is also negatively affected by the presence of the JAK2(V617F) mutation. To investigate the impact of JAK2(V617F) mutation burden and histology on outcome, we collected 475 WHO-diagnosed ET (69.2%) or early-PMF JAK2(V617F) -positive patients followed in 4 Italian haematology centers. JAK2(V617F) allele burden was ≤50% in 90% and 87% of ET and early-PMF patients, respectively (P = ...

BACKGROUND AND AIMS: Prescription Drug Monitoring Programs (PDMPs) are a principal strategy used in the USA to address prescription drug abuse. We (1) compared opioid use pre- and post-PDMP implementation and (2) estimated differences of PDMP impact by reason for Medicare eligibility and plan type. DESIGN: Analysis of opioid prescription claims in US states that implemented PDMPs relative to non-PDMP states during 2007-2012. SETTING: Florida, Louisiana, Nebraska, New Jersey, Vermont, Georgia, Wisconsin, Maryland, New Hampshire, and Arkansas, USA...

OBJECTIVE Spinal epidural abscesses (SEAs) can be difficult to diagnose and may result in neurological compromise or even death. Delays in diagnosis or treatment may worsen the prognosis. While SEA presents a high risk for litigation, little is known about the medicolegal ramifications of this condition. An enhanced understanding of potential legal implications is important for practicing spine surgeons, emergency medicine physicians, and internists. METHODS The VerdictSearch database, a large legal-claims database, was queried for "epidural abscess"-related legal cases...

BACKGROUND: Pemetrexed (PEM) is a new-generation multitargeted antifolate agent with a demonstrated broad-spectrum activity in several types of human cancers, including non-small cell lung cancer (NSCLC) and mesothelioma. Major side effects include dose-limiting hematologic toxicities. PEM nephrotoxicity is well known; however, its frequency is considered to be low. CASE PRESENTATION: Here we report two cases of acute kidney injury (AKI) related to PEM administration (500 mg/m2) in patients with NSCLC...

A preference for smooth curvature, as opposed to angularity, is a well-established finding for lines, two-dimensional shapes, and complex objects, but little is known about individual differences. We used two-dimensional black-and-white shapes-randomly generated irregular polygons, and arrays of circles and hexagons-and measured many individual differences, including artistic expertise, personality, and cognitive style. As expected, people preferred curved over angular stimuli, and people's degree of curvature preference correlated across the two sets of shapes...

Azacytidine (5-AZA) is the standard first-choice treatment for high-risk myelodysplasia (MDS) patients. However, the clinical outcome for those patients who interrupt treatment or whose disease failed to respond is very poor. In order to identify the cellular pathways that are modified by long-term exposure to 5-AZA, we evaluated key proteins associated with the autophagy pathway by reverse-phase microarray (RPPA). Comparing bone marrow mononucleated cells (BMMCs) obtained from 20 newly-diagnosed patients and after four 5-AZA cycles we found an increased autophagy signaling...

BACKGROUND: Because acute compartment syndrome is one of the few limb-threatening and life-threatening orthopaedic conditions and is difficult to diagnose, it is a frequent source of litigation. Understanding the factors that lead to plaintiff verdicts and higher indemnity payments may improve patient care by identifying common pitfalls. METHODS: The VerdictSearch legal claims database was queried for the term "compartment syndrome." After 46 cases were excluded for missing information or irrelevancy, 139 cases were reviewed...

Approximately 25% of melanoma patients with locoregional metastases are nonresponsive to new molecular target therapy and immunotherapy. When metastases are located in the pelvis, melphalan hypoxic perfusion can be an optional treatment. Because methylation of MGMT promoter increases the efficacy of alkylating agents, studies on melanoma outcome of patients treated with melphalan regional chemotherapy should consider this epigenetic change. This study aims to evaluate whether the survival of stage III melanoma patients treated with melphalan regional chemotherapy may be correlated with MGMT methylation status...

This diagnostic accuracy study compared the accuracy of seizure detection by amplitude-integrated electroencephalography with the criterion standard conventional video EEG in term and near-term infants at risk of seizures. Simultaneous recording of amplitude-integrated EEG (2-channel amplitude-integrated EEG with raw trace) and video EEG was done for 24 hours for each infant. Amplitude-integrated EEG was interpreted by a neonatologist; video EEG was interpreted by a neurologist independently. Thirty-five infants were included in the analysis...

Higher HIV diversity has been associated with virologic outcomes in children on antiretroviral treatment (ART). We examined the association of HIV diversity with virologic outcomes in adults from the HPTN 052 trial who initiated ART at CD4 cell counts of 350-550 cells/mm3. A high resolution melting (HRM) assay was used to analyze baseline (pre-treatment) HIV diversity in six regions in the HIV genome (two in gag, one in pol, and three in env) from 95 participants who failed ART. We analyzed the association of HIV diversity in each genomic region with baseline (pre-treatment) factors and three clinical outcomes: time to virologic suppression after ART initiation, time to ART failure, and emergence of HIV drug resistance at ART failure...

Cancer has been mainly treated by traditional therapeutic approaches which do not consider the human genetic diversity and present limitations, probably as a consequence of a poor knowledge of both patient's genetic background and tumor biology. Due to genome project conclusion and large scale gene analyses emergence, the therapeutic management of several prevalent and aggressive tumors has dramatically improved and represents the closest examples of a precision medicine intervention in this field. Nonetheless, prostate cancer (PCa) remains as a challenge to personalized medicine implementation, probably due to its notorious heterogeneous molecular profile...

PURPOSE: Breast cancer (BC) diagnosis in young adults (YA) is rising, and both disease and treatments are aggressive in this population. Evidence supports the use of physical activity in reducing shoulder dysfunction, which is common among BC survivors. A pilot randomized clinical trial was performed to determine the effectiveness of a 12-week post-radiation exercise program in minimizing upper extremity dysfunction in YA with BC. METHODS: Participants were randomized to either an exercise arm or a control arm receiving standard care...

Studies regarding macroalgal responses to ocean acidification (OA) are mostly limited to short-term experiments in controlled conditions, which hamper the possibility to scale up the observations to long-term effects in the natural environment. To gain a broader perspective, we utilized volcanic CO2 vents as a "natural laboratory" to study OA effects on Sargassum vulgare at different time scales. We measured photosynthetic rates, oxidative stress levels, antioxidant contents, antioxidant enzyme activities, and activities of oxidative metabolic enzymes in S...

Tissue engineering has emerged as a new approach with the potential to overcome the limitations of traditional therapies. The objective of this study was to test whether our polymeric scaffold is able to resist the corrosive action of bile and to support a cell's infiltration and neoangiogenesis with the aim of using it as a biodegradable tissue substitute for serious bile duct injuries. In particular, a resorbable electrospun polyhydroxyethyl-aspartamide-polylactic acid (90 mol% PHEA, 10 mol% PLA)/polycaprolactone (50:50 w/w) plate scaffold was implanted into rabbit gallbladder to assess the in vivo effects of the lytic action of the bile on the scaffold structure and then as a tubular scaffold to create a biliary-digestive anastomosis as well...

Multiple myeloma (MM) is a hematologic malignancy characterized by proliferation of malignant plasma cells. patient outcome has improved markedly over the last decades due to the introduction of novel therapeutic agents such as bortezomib, thalidomide and lenalidomide. However, MM still remains largely incurable and patients eventually become refractory to available treatments. To address this unmet medical need, a variety of new molecules are currently being developed in preclinical models and/or are being investigated in clinical studies...
