Objectives: Nasal packing after endoscopic sinus surgery is frequently used to control postoperative bleeding, enhance the wound healing process, and prevent lateralization of the middle turbinate, which causes insufficient ventilation. Many biodegradable materials have been developed to reduce pain and mucosal damage during packing removal. The purpose of this study was to compare the efficacy of Guardcel (Genewel Co.) middle meatal packing with a traditional nonabsorbable middle meatal packing, Merocel (Medtronic Xomed), on wound healing and patient satisfaction...

Morphine is viewed as one of the classical treatments for intractable pain, but its role is limited by side effects, including analgesic tolerance. A few chemokines have been reported to be engaged in the mechanisms of morphine tolerance. However, the exact roles of CXCL11 in chronic morphine tolerance remain unknown. In this study, Walker 256 mammary gland carcinoma cells were inoculated into the tibia of rats to provoke cancer-induced bone pain (CIBP). Then morphine was intrathecally administered twice daily for 7 consecutive days to induce drug tolerance...

BACKGROUND: The most common sequela of neonatal brachial plexus palsy is an internal rotation contracture of the shoulder that impairs function and leads to skeletal deformation of the glenohumeral joint. Treatment options include release, transfers, and humeral osteotomy, all ultimately striving for better function through increased external rotation. Prior studies have shown that neonatal brachial plexus palsy alters humeral retroversion but with conflicting findings. We studied retroversion in children with internal rotation contractures from neonatal brachial plexus palsy to clarify its effect on version and surgical planning...

Camptothecin (CPT) is a potent chemotherapeutic agent that shows a broad spectrum of anticancer activities. However, it is clinically inactive because of poor aqueous solubility, rapid aqueous hydrolysis, and unexpected side effects. Three strategies have extensively been adopted to improve its dissolution rate including reduction of drug particle size to a nanoscale, use of an amorphous state, and the formation of inclusion compounds. In our study, we combined these three strategies together by constructing CPT nanoparticles by creating an inclusion complex with β-cyclodextrin (BCD)...

ACY-241 is a novel, orally available and selective histone deacetylase (HDAC) 6 inhibitor in Phase 1b clinical development in multiple myeloma (NCT 02400242). Like the structurally related drug ACY-1215 (ricolinostat), ACY-241 has the potential for a substantially reduced side effect profile versus current nonselective HDAC inhibitor drug candidates due to reduced potency against Class I HDACs while retaining the potential for anticancer effectiveness. We now show that combination treatment of xenograft models with paclitaxel and either ricolinostat or ACY-241 significantly suppresses solid tumor growth...

EZH2 is a critical epigenetic regulator that is deregulated in various types of cancers including multiple myeloma (MM). In the present study, we hypothesized that targeting EZH2 might induce apoptosis in myeloma cells including stem cell-like cells (CSCs). We investigated the effect of EZH2 inhibition on MM cells using a potent inhibitor (GSK126). The results showed that GSK126 effectively abrogated the methylated histone 3 (H3K27me3) level in MM.1S and LP1 cells, and inhibited the number of live cells and colony formation in soft agar of six MM cell lines...

A metallic taste is reported by cancer patients as a side effect of systemic therapy. Despite the high prevalence, this taste alteration has received limited attention. The present study investigated: 1) the prevalence of metallic taste in cancer patients treated with systemic therapy; 2) possible predictors of metallic taste; and 3) characteristics of metallic taste. A heterogeneous population of 127 cancer patients, who had received systemic treatment in the past year or were still on treatment, completed a questionnaire developed for this study...

INTRODUCTION: Whether patients take their medication as prescribed is of increasing importance in adolescent psychiatry since both the number of efficacious pharmaceutical treatments and the rate of prescriptions of psychotropic compounds are on the rise. Previous research showed high rates of medication nonadherence among both adolescents with medical disorders and adult patients with psychiatric disorders. METHODS: The present review was performed according to PRISMA guidelines and evaluates existing scientific literature concerning adherence to psychotropic medication among adolescents...

The goal of drug delivery is to deliver therapeutics to the site of disease while reducing unwanted side effects. In recent years, a diverse variety of synthetic nano and microparticles have been developed as drug delivery systems. The success of these systems for drug delivery lies in their ability to overcome biological barriers such as the blood-brain barrier, to evade immune clearance and avoid nonspecific biodistribution. This Review provides an overview of recent advances in the design of biohybrid drug delivery systems, which combine cells with synthetic systems to overcome some of these biological hurdles...

This qualitative descriptive study explored cancer survivors' experiences of barriers and facilitators to undertaking physical activity to inform how services and professionals might offer better support. Purposive and theoretical sampling was used to recruit 25 people who were up to 5 years post-cancer diagnosis. Participants took part in face to face, semi-structured interviews, and transcripts were analysed using thematic analysis. The analysis identified five interrelated themes which represented cancer survivors' views: 1) You're on your own-a sense of abandonment post-treatment, and lack of sufficient and tailored information; 2) Dis-ease-disruption to self and identity, and a heightened awareness of physical self and fragility; 3) Becoming acclimatised-physical activity in the face of treatment-related side effects and residual impairment; 4) Importance of others-encouragement and support from health professionals, family and friends, and cancer-specific exercise groups; 5) Meanings people ascribed to physical activity-these were central and could help or hinder engagement...

Mass transfer coefficients of the water boundary layer (kw ) were measured using alabaster dissolution kinetics in a diffusion cell that was operated at stirring rates between 90 and 600 min(-1) , aiming to provide a more robust characterisation of the effect of hydrodynamics on the uptake of polar compounds by passive samplers, as compared with characterisations in terms of stirring rates and water flow velocities. The measured kw helped to quantitatively understand calcium sulphate transport through a poly(ethersulfone) membrane and two water boundary layers (at both sides of the membrane)...

Rapid maxillary expansion (RME) is the technique of increasing the transverse dimension of the upper jaw using lateral forces applied by palatal expander. Usually, this palatal appliance is anchored on posterior teeth. The purposes of this computer simulation study were to analyze the stress and strain distribution generated in the maxilla, mainly in midpalatal suture (MPS), during RME by tooth-borne and bone-borne expanders and to study the correlation between mechanical strain and Wolff's Law. The analysis was performed with finite element models developed based on Cone Beam computed tomography (CT)...

Anti-epidermal growth factor receptor (EGFR) drugs such as erlotinib and gefitinib cause a side effect of hypomagnesemia, but chemotherapy to treat this has not yet been developed. The transient receptor potential melastatin 6 (TRPM6) channel is involved in the reabsorption of Mg(2+) in the renal tubule. We reported previously that the expression of TRPM6 is up-regulated by epidermal growth factor (EGF) in renal tubular epithelial NRK-52E and HEK293 cells. EGF-induced elevation of TRPM6 expression was inhibited by erlotinib, gefitinib, and lapatinib...

OBJECTIVE: The effect of antipsychotic medication on brain structure remains unclear. Given the prevalence of weight gain as a side-effect, body mass index (BMI) change could be a confounder. METHOD: Patients with first-episode psychosis (n = 78) and healthy controls (n = 119) underwent two 1.5T MRI scans with a 1-year follow-up interval. siena (fsl 5.0) was used to measure whole-brain volume change. Weight and height were measured at both time points. Antipsychotic medication use at baseline and follow-up was converted into chlorpromazine equivalent dose and averaged...

Acute respiratory distress syndrome occupies a great deal of attention in intensive care units. Despite ample knowledge of the physiopathology of this syndrome, the focus in intensive care units consists mostly of life-supporting treatment and avoidance of the side effects of invasive treatments. Although great advances in mechanical ventilation have occurred in the past 20 years, with a significant impact on mortality, the incidence continues to be high. Patients with acute respiratory distress syndrome, especially the most severe cases, often present with refractory hypoxemia due to shunt, which can require additional treatments beyond mechanical ventilation, among which is mechanical ventilation in the prone position...
