therapy related late adverse events in hodgkin s lymphoma

Hodgkin's lymphoma (HL) is one of the most curable hematologic diseases with an overall response rate over 80%. However, despite this therapeutic efficacy, HL survivors show a higher morbidity and mortality than other people of the same age because of long-term therapy-related events. In the last decades, many efforts have been made to reduce these effects through the reduction of chemotherapy dose, the use of less toxic chemotherapeutic agents, and the introduction of new radiation techniques. In this paper, we will describe the main long-term effects related to chemotherapy and radiotherapy for HL, the efforts to reduce toxicity made in the last years, and the clinical aspects which have to be taken into consideration in the followup of these patients

Omic Approach in Non-Smoker Female with Lung Squamous Cell Carcinoma Pinpoints to Germline Susceptibility and Personalized Medicine

Lung cancer is strongly associated to tobacco smoking. However, global statistics estimate that in females the proportion of lung cancer cases that is unrelated to tobacco smoking reaches fifty percent, making questionable the etiology of the disease

Italian real life experience with ibrutinib: Results of a large observational study on 77 relapsed/refractory mantle cell lymphoma

Although sometimes presenting as an indolent lymphoma, mantle cell lymphoma (MCL) is an aggressive disease, hardly curable with standard chemo-immunotherapy. Current approaches have greatly improved patients' outcomes, nevertheless the disease is still characterized by high relapse rates. Before approval by EMA, Italian patients with relapsed/refractory MCL were granted ibrutinib early access through a Named Patient Program (NPP). An observational, retrospective, multicenter study was conducted. Seventyseven heavily pretreated patients were enrolled. At the end of therapy there were 14 complete responses and 14 partial responses, leading to an overall response rate of 36.4%. At 40 months overall survival was 37.8% and progression free survival was 30%; disease free survival was 78.6% at 4 years: 11/14 patients are in continuous complete response with a median of 36 months of follow up. Hematological toxicities were manageable, and main extra-hematological toxicities were diarrhea (9.4%) and lung infections (9.0%). Overall, 4 (5.2%) atrial fibrillations and 3 (3.9%) hemorrhagic syndromes occurred. In conclusions, thrombocytopenia, diarrhea and lung infections are the relevant adverse events to be clinically focused on; regarding effectiveness, ibrutinib is confirmed to be a valid option for refractory/relapsed MCL also in a clinical setting mimicking the real world

Cellular and mitochondrial determination of low molecular mass organic acids by LC-MS/MS

A selective and sensitive method for the determination of low molecular mass organic acids (LMMOAs) in cell and mitochondrial extracts is presented. The analytical method consists in the separation by reversed phase liquid chromatography and detection with tandem mass spectrometry (LC-MS/MS) of the LMMOAs like malic, succinic, formic and citric acids. These acids are among the cellular intermediates of the tricarboxylic acid cycle (TCA), thus their quantitation can provide essential information about the catabolic and anabolic processes occurring in cells under physiological and pathological conditions. The analytical method was fully validated in terms of linearity, detection and quantification limits, recovery and precision. Detection limits (LOD) for malic, succinic and fumaric acids were in the range of 1-10 nM, while 20 nM was obtained for citric acid. Analytical recovery in cell and mitochondrial extracts was found between 88 and 105% (CV% <7.1) and matrix effect was estimated to be less than 108%. The LC-MS/MS method applied to the quantification of TCA cycle metabolites revealed a different distribution of the four acids in cells and mitochondria, and it could be used to monitoring metabolic alterations associated with TCA cycle and oxidative phosphorylation dysfunctions

Differentiation of modern and ancient varieties of common wheat byquantitative capillary electrophoretic profile of phenolic acids

Phenolic compounds have received great attention among the health promoting phytochemicals in com-mon wheat (Triticum aestivum L.), mainly because of their strong antioxidant properties. In the presentstudy a simple Capillary Zone Electrophoresis (CZE) method with UV detection was optimized and vali-dated for the quantitation of six of the most important phenolic acids in whole grain i.e., sinapic, ferulic,syringic, p-coumaric, vanillic and p-hydroxybenzoic acid. The separation was achieved in a running buffercomposed of sodium phosphate solution (50 mM) in water/methanol 80:20 (v/v) at pH 6.0 and using afused-silica capillary at the temperature of 30\u25e6C under application of 27 kV. By means of diode arraydetector, and made possible by the favorable characteristic UV spectra, the quantitation of the soluteswas carried out at 200, 220 and 300 nm, in the complex matrices represented by the soluble and boundfractions of wheat flours. The validation parameters of the method i.e., linearity, sensitivity, precision,accuracy and robustness were in line with those obtained by consolidated separation techniques appliedfor the same purposes (e.g., HPLC-UV), with a significant advantage in term of analysis time (less than12 min). Ten varieties of soft wheat (five modern Italian and five old Italian genotypes) were analysed andthe data were subjected to Principal Components Analysis (PCA). Interestingly, significant differences ofthe quantitative phenolic acids profile were observed between the modern and the ancient genotypes,with the latter showing higher amount of the main represented phenolic acids

Printing MEMS: Application of Inkjet Techniques to the Manufacturing of Inertial Accelerometers

In the last few years, the manufacturing of microelectromechanical systems (MEMS) by means of innovative tridimensional and bidimensional printing technologies has significantly catalyzed the attention of researchers. Inkjet material deposition, in particular, can become a key enabling technology for the production of polymer-based inertial sensors characterized by low cost, high manufacturing scalability and superior sensitivity. In this paper, a fully inkjet-printed polymeric accelerometer is proposed, and its manufacturing steps are described. The manufacturing challenges connected with the inkjet deposition of SU-8 as a structural material are identified and addressed, resulting in the production of a functional spring-mass sensor. A step-crosslinking process allows optimization of the final shape of the device and limits defects typical of inkjet printing. The resulting device is characterized from a morphological point of view, and its functionality is assessed in performing optical readout. The acceleration range of the optimized device is 0–0.7 g, its resolution is 2 × 10−3 g and its sensitivity is 6745 nm/g. In general, the work demonstrates the feasibility of polymeric accelerometer production via inkjet printing, and these characteristic parameters demonstrate their potential applicability in a broad range of uses requiring highly accurate acceleration measurements over small displacements

Sternal reconstruction by extracellular matrix: A rare case of phaces syndrome

Congenital defects of the sternum are rare and due to a failure of midline development and fusion of the sternal bones. Surgical correction of a sternal cleft should be preferred during infancy for functional reasons. Chest wall reconstruction represented a complex problem in the last decades. We report our successful outcome of sternal reconstruction in a rare case of PHACES syndrome, in which the patient was submitted to reconstruction of the sternum and complete closure of the thoracic defect by the employ of an extracellular matrix XCM Biologic tissue matrix. We promote the use of extracellular matrix in surgical reconstruction of chest defects for its maneuverability, plasticity, tolerability and the possibility of growing with the children's chest getting a good compliance and optimal cosmetic results
