Image guided thermosensitive liposomes for focused ultrasound drug delivery: Using NIRF labelled lipids and topotecan to visualise the effects of hyperthermia in tumours.

Image guided drug delivery using imageable thermosensitive liposomes (iTSLs) and high intensity focused ultrasound (FUS or HIFU) has attracted interest as a novel and non-invasive route to targeted delivery of anti-cancer therapeutics. FUS-induced hyperthermia is used as an externally applied "trigger" for the release of a drug cargo from within thermosensitive drug carriers. It is suggested that sub-ablative hyperthermia significantly modifies the permeability of tumour vasculature and enhances nanoparticl...

The aim of this systematic review is to investigate the validity of the hypothesis that hyperthermia added to radiotherapy and/or chemotherapy improves treatment outcome for pancreatic cancer patients.

Structural, microrheological and kinetic properties of a ternary silica-Pluronic F127-starch thermosensitive system.

The sol-gel transition in aqueous suspensions consisting of silica particles and thermosensitive polymer is controlled by inter-particle forces and solution properties of the polymer. Addition of a second non-thermosensitive polymer may affect the transition. The purpose of this work was to characterize the kinetics of the sol-gel transition and to understand the effects of a second non-thermosensitive polymer on the microstructure, using a combination of classical rheology and microrheology.

Malignant Hyperthermia Versus Thyroid Storm in a Patient With Symptomatic Graves Disease: A Case Report.

Malignant hyperthermia and thyroid storm are intraoperative emergencies with overlapping symptoms but different treatment protocols. We faced this diagnostic dilemma in a 25-year-old patient with symptomatic hyperthyroidism, elevated free T3 and free T4, and low thyroid-stimulating hormone from Graves disease despite treatment with propranolol 80 mg daily and methimazole 40 mg every 8 hours. During thyroidectomy, he developed hyperthermia and hypercarbia without tachycardia. When the rate of rise of PaCO2 a...

False-Positive 18F-FDG PET/CT Due to Filgrastim That Induced Extramedullary Liver Hematopoiesis in a Burkitt Lymphoma.

We report a case of Burkitt lymphoma with largely extranodal disease localizations at staging. Chemotherapy was given, thus obtaining a complete metabolic response in all previous disease sites as shown at a control PET, however associated to the appearance of new focal uptake areas in the liver; these findings were confirmed at US and MRI. Chemotherapy determined also neutropenia that was treated by filgrastim, followed by a prompt and important medullary response. Liver biopsy revealed extramedullary hema...

Ultrasound Doppler as an Imaging Modality for Selection of Murine 4T1 Breast Tumors for Combination Radiofrequency Hyperthermia and Chemotherapy.

Noninvasive radiofrequency-induced (RF) hyperthermia has been shown to increase the perfusion of chemotherapeutics and nanomaterials through cancer tissue in ectopic and orthotopic murine tumor models. Additionally, mild hyperthermia (37°C-45°C) has previously shown a synergistic anticancer effect when used with standard-of-care chemotherapeutics such as gemcitabine and Abraxane. However, RF hyperthermia treatment schedules remain unoptimized, and the mechanisms of action of hyperthermia and how they chan...

Glucosylsphingosine Causes Hematological and Visceral Changes in Mice-Evidence for a Pathophysiological Role in Gaucher Disease.

Glucosylceramide and glucosylsphingosine are the two major storage products in Gaucher disease (GD), an inherited metabolic disorder caused by a deficiency of the lysosomal enzyme glucocerebrosidase. The build-up of glucosylceramide in the endoplasmic reticulum and prominent accumulation in cell lysosomes of tissue macrophages results in decreased blood cell and platelet counts, and skeletal abnormalities. The pathological role of the deacylated form of glucosylceramide, glucosylsphingosine (lyso-Gb1), a re...

This study assessed the effect of pegfilgrastim in patients with early stage breast cancer who were receiving docetaxel and cyclophosphamide(TC)therapy(75mg/m / 2 docetaxel plus 600 mg/m2 cyclophosphamide). In total, 17 patients who were to receive 4 planned cycles of TC therapy every 3 weeks were included in this study. Of the 17 patients, 10 who received pegfilgrastim after January 2016 formed the Peg-G group and 7 who did not receive pegfilgrastim until December 2015 formed the control group. We observed...

Assurance of Myeloid Growth Factor Administration in an Infusion Center: Pilot Quality Improvement Initiative.

Four incident reports involving missed doses of myeloid growth factors (MGFs) triggered the need for an outcome-driven initiative. From March 1, 2015, to February 29, 2016, at University of California Irvine Health Chao Infusion Center, 116 of 3,300 MGF doses were missed (3.52%), including pegfilgrastim, filgrastim, and sargramostim. We hypothesized that with the application of Lean Six Sigma methodology, we would achieve our primary objective of reducing the number of missed MGF doses to < 0.5%.

RFX1 participates in doxorubicin-induced hepatitis B virus reactivation.

Cytotoxic chemotherapy drugs, including doxorubicin, can directly promote hepatitis B virus (HBV) replication, but the mechanism has not been fully clarified. This study investigated the potential mechanism underlying the cytotoxic chemotherapy-mediated direct promotion of HBV replication. We found that HBV replication and regulatory factor X box 1 gene (RFX1) expression were simultaneously promoted by doxorubicin treatment. The amount of RFX1 bound to the HBV enhancer I was significantly increased under do...

Cost-benefit Analysis of Maintaining a Fully Stocked Malignant Hyperthermia Cart versus an Initial Dantrolene Treatment Dose for Maternity Units.

The Malignant Hyperthermia Association of the United States recommends that dantrolene be available for administration within 10 min. One approach to dantrolene availability is a malignant hyperthermia cart, stocked with dantrolene, other drugs, and supplies. However, this may not be of cost benefit for maternity units, where triggering agents are rarely used.

The targeted drug delivery with the help of nanocarriers and the controlled drug release at the lesion sites are the most effective ways to enhance therapeutic efficacy and reduce side effects. Here, we built a light sensitive liposome (Her2-I&D-LSL) which was formed by a special phospholipid (PLsPC) and a hydrophobically modified photosensitizer (ICG-ODA). DOX was employed as the therapeutic drug, encapsulating in the internal phase of the liposome whose surface was modified by Her2 antibodies for recogniz...

Globotriaosylsphingosine (Lyso-Gb3) as a biomarker for cardiac variant (N215S) Fabry disease.

Fabry disease (FD) is a multi-systemic X-linked lysosomal disorder caused by the deficient activity of α-galactosidase-A enzyme, which leads to accumulation of glycosphingolipids in various body tissues. The N215S mutation is a known variant of FD, with a late onset cardiac phenotype. Consensus guidelines acknowledged the use of globotriaosylsphingosine (Lyso-Gb3) as a diagnostic marker for classical FD but its utility for cardiac variant FD is not clear. We aim to characterize the clinical features and ev...

Highly penetrative liposome nanomedicine generated by a biomimetic strategy for enhanced cancer chemotherapy.

Liposome nanomedicine has been successfully applied for cancer chemotherapy in patients. However, in general, the therapeutic efficacy is confined by its limited accumulation and penetration in solid tumors. Here, we established a biomimetic strategy for the preparation of highly penetrative liposome nanomedicine for enhanced chemotherapeutic efficacy. By applying this unique type of nanomedicine, membrane proteins on the cancer cells are used as highly penetrative targeting ligands. Biomimetic liposomes ar...
