Natural products have been used for the treatment of various diseases such as cancer. Curcumin (CUR) and sulforaphane (SF) have anti-cancer effects, but their application is restricted because of their low water solubility and poor oral bioavailability. To improve the bioavailability and solubility of SF and CUR, we performed an advanced delivery of SF and CUR with PEGylated gold coated Fe3O4 magnetic nanoparticles (PEGylated Fe3O4@Au NPs) to endorse SF and CUR maintenance as an effective and promising antitumor drugs...

We performed a systematic review of the literature to establish conclusive evidence of risk factors for community-acquired pneumonia (CAP). Observational studies (cross-sectional, case-control, and cohort studies) the primary outcome of which was to assess risk factors for CAP in both hospitalized and ambulatory adult patients with radiologically confirmed pneumonia were selected. The Newcastle-Ottawa Scale specific for cohort and case-control designs was used for quality assessment. Twenty-nine studies (20 case-control, 8 cohort, and 1 cross-sectional) were selected, with 44...

Median overall survival (OS) of patients with metastatic colorectal cancer (mCRC) has reached up to 30months in recent clinical trials of first line therapies. Following disease progression after the standard in both, 1st and 2nd line, combination chemotherapy with monoclonal antibodies, many patients maintain a good performance status and a significant proportion is motivated to undergo further therapy. Choices of treatment beyond the second line setting for mCRC are therefore becoming increasingly important...

PURPOSE: Keratinization is a routinely reported histologic feature in head and neck cancer. In contrast to numerous clinicopathologic parameters, the prognostic value of keratinization in oral squamous cell carcinoma (OSCC) is rarely reported in the literature. The purpose of this study was to review the outcome of patients with OSCC with a special focus on the degree of keratinization. PATIENTS AND METHODS: In this retrospective cohort study, we evaluated the medical records at the Department of Oral and Maxillofacial Surgery, Jena University Hospital, and investigated the outcome of patients with OSCC with disease-free survival and disease-specific survival according to the degree of keratinization...

Although evidence-based treatment guidelines recommend low-molecular-weight heparin (LMWH) monotherapy for cancer-associated thrombosis (CAT), adherence to outpatient treatment guidelines for CAT still needs improvement. One of the challenges that clinicians face in treating CAT with LMWH is patient preference for oral anticoagulants over daily LMWH injections. This article aims to provide oncology nurses with practical advice on patient education to increase patient acceptance of and adherence to LMWH treatment for CAT...

BACKGROUND: Higher rates of local recurrences and second primaries, ascribable to field cancerization, are known problem in oral cancers. The present study explored utility of identification of potential recurrences by Raman spectroscopy, which has been shown to identify oral precancers, cancers, and field cancerization in humans and micro-sized mechanical irritation-induced tumors in animals. METHODS: Raman spectra were acquired from tumor and contralateral normal mucosa in 99 patients with oral cancer who were then followed up for appearance of clinically apparent cancerous lesions...

Although oral drug delivery is the most common route of drug administration, the conventional polymeric nanocarriers exhibit a low drug loading capacity and low stability in the gastrointestinal (GI) environments. In this study, a newly designed silica-containing redox nanoparticle (siRNP) with reactive oxygen species (ROS) scavenging capacity is developed as an ideal oral nanocarrier for a novel hydrophobic anticancer compound BNS-22 to treat colitis-associated colon cancer in vivo. Crosslinking of silica moieties significantly enhances the stability under acidic conditions and improves BNS-22 loading capacity of siRNP compared to the conventional redox nanoparticle...

MCAM/CD146 (melanoma cell adhesion molecule/CD146) is a transmembrane immunoglobulin superfamily cell adhesion molecule involved in transendothelial migration and signal transduction. It is expressed in melanoma, squamous cell carcinoma, prostatic, ovarian, cervical and endometrial cancers and promotes tumour growth, angiogenesis and metastasis. Melanoma is the most common malignant oral tumour of dogs and also arises in the skin, nail bed and footpad. The aim of this study was to investigate the immunohistochemical expression of MCAM/CD146 in 51 canine melanomas, including oral, cutaneous and ocular tumours...

BACKGROUND: For patients with non-small-cell lung cancer (NSCLC) and multiple brain metastases, whole-brain irradiation (WBI) is a standard-of-care treatment, but its effects on neurocognition are complex and concerning. We compared the efficacy of an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), icotinib, versus WBI with or without chemotherapy in a phase 3 trial of patients with EGFR-mutant NSCLC and multiple brain metastases. METHODS: We did a multicentre, open-label, parallel randomised controlled trial (BRAIN) at 17 hospitals in China...

Described as a Btk inhibitor, ibrutinib also potently inhibits Bmx and EGFR, two good targets for lung cancer. Owing to its high CLogP (4.07) and low aqueous solubility (<0.01mg/ml), resulting in unfavorable bioavailability, ibrutinib requires high dosages to achieve good clinical response in the treatment of non-small cell lung cancer (NSCLC). In our effort to improve the CLogP of ibrutinib by structural optimization led to the discovery of a potent anti-cancer agent B6, with beneficial physicochemical parameters (CLogP=2...

BACKGROUND: Metformin is a biguanide oral hypoglycaemic agent commonly used for the treatment of type 2 diabetes mellitus. In addition to its anti-diabetic effect, metformin has also been associated with a reduced risk of cancer incidence of a number of solid tumours, including prostate cancer (PCa). However, the underlying biological mechanisms for these observations have not been fully characterised in PCa. One hypothesis is that the indirect insulin lowering effect may have an anti-neoplastic action as elevated insulin and insulin like growth factor - 1 (IGF-1) levels play a role in PCa development and progression...
