BACKGROUND: This study characterized a cohort of chronic obstructive pulmonary disease (COPD) patients on maintenance bronchodilator monotherapy for ≥6 months to establish their disease burden, measured by health care utilization. METHODS: Data were extracted from the UK Clinical Practice Research Datalink and linked to Hospital Episode Statistics. The monotherapy period spanned the first prescription of a long-acting β2-adrenergic agonist or a long-acting muscarinic antagonist until the end of the study (December 31, 2013) or until step up to dual/triple therapy, for example, addition of another long-acting bronchodilator, an inhaled corticosteroid, or both...

Poly (ADP-ribose) polymerase-1 (PARP1) is a highly conserved enzyme focused on the self-repair of cellular DNA damage. Until now, numbers of PARP inhibitors have been reported and used for breast cancer therapy in recent years, especially in TNBC. However, developing a new type PARP inhibitor with distinctive skeleton is alternatively promising strategy for TNBC therapy. In this study, based on co-crystallization studies and pharmacophore-docking-based virtual screening, we discovered a series of dihydrodibenzo[b,e]-oxepin compounds as PARP1 inhibitors...

AIM: Triple-negative breast cancer (TNBC), defined by the absence of receptors for estrogen, progesterone and human epithelial receptor 2 (HER2), is a recalcitrant disease in need of effective therapy. We previously isolated very-highly metastatic variants of the TNBC cell line MDA-MB-231 using serial orthotopic implantation of MDA-MB-231 human breast cancer cells in nude mice. MATERIALS AND METHODS: MDA-MB-231 cells expressing red fluorescent protein (MDA-MB-231-RFP) (1×10(7) cells/site) were initially injected subcutaneously in the flank of nude mice...

Budget constrictions have pushed some researchers to explore whether antiretroviral therapy with one or two drugs instead of the well-established triple-drug regimens may be able to maintain undetectable viremia in HIV-infected individuals, at least used as simplification in patients already with viral suppression under standard triple therapy. With the advent of co-formulations and the improved safety of the newest antiretroviral agents, there is no other reason than cost to justify moving from triple to dual or monotherapy...

BACKGROUND: To shorten the course of direct-acting antiviral agents for chronic hepatitis C virus (HCV) infection, we examined the antiviral efficacy and safety of 3 weeks of response-guided therapy with an NS3 protease inhibitor and dual NS5A inhibitor-NS5B nucleotide analogue. METHODS: In this open-label, phase 2a, single centre study, Chinese patients with chronic HCV genotype 1b infection without cirrhosis were randomly allocated by a computer program to one of three treatment groups (sofosbuvir, ledipasvir, and asunaprevir; sofosbuvir, daclatasvir, and simeprevir; or sofosbuvir, daclatasvir, and asunaprevir) until six patients in each group (1:1:1) achieved an ultrarapid virological response (plasma HCV RNA <500 IU/mL by day 2, measured by COBAS TaqMan HCV test, version 2...

BACKGROUND: Because of difficulties with early diagnosis, most patients with pancreatic cancer receive chemotherapy. The National Comprehensive Cancer Network guidelines (version 2.2015) suggest therapy with gemcitabine (GEM) plus nab-paclitaxel (nPTX) as a category 1 recommendation for metastatic pancreatic ductal adenocarcinoma. According to the results of many studies, the activation of chemotherapeutic agents-induced nuclear factor-κB (NF-κB) causes chemoresistance. Hence, we hypothesized that the addition of nafamostat mesilate (NM), a potent NF-κB inhibitor, to GEM/nPTX therapy could enhance the antitumor effect in the treatment of pancreatic ductal adenocarcinoma...

Targeting double-stranded DNA (dsDNA) with high affinity and specificity has become a hot topic in biochemistry and molecular biology research. Gene diagnosis and therapy, DNA manipulation, and gene expression regulation could be achieved based on certain recognition principles through specific interactions between dsDNA and natural nucleotides or synthesized ligands. Some ligands (e.g., peptide nucleic acids (PNAs), triple helix-forming oligonucleotides (TFOs), oligopolyamides, and zinc-finger peptides) show sufficient affinity and specificity for targeting dsDNA sequences...

Early detection of breast cancer is a critical component in patient prognosis and establishing effective therapy regimens. Here, we developed an easily accessible yet potentially powerful sensor to detect cancer cell targets by utilizing seven dual-ligand cofunctionalized gold nanoclusters (AuNCs) as both effective cell recognition elements and signal transducers. On the basis of this AuNC multichannel sensor, we have successfully distinguished healthy, cancerous and metastatic human breast cells with excellent reproducibility and high sensitivity...

Anti-PD-1 treatment increases anti-tumour immune responses in animal models of hepatocellular carcinoma (HCC). Sorafenib, the mainstay of treatment of HCC patients, however, leads to tumour hypoxia and thereby abrogates the efficacy of anti-PD-1 treatment. This served as a rationale to implement CXCR4 inhibition as adjunct to sorafenib and anti-PD-1 treatment in murine HCC models. We studied the relationship between tumour hypoxia, PD-L1 and CXCL12 expression in human HCC, aiming to test the rationale for triple therapy combining sorafenib, PD-1 immune checkpoint inhibitors and CXCR4 inhibitors...

While HIV-2 is a causative agent for AIDS in addition to the better studied HIV-1, there is currently no suitable animal model for experimental studies for HIV-2 infection and evaluating promising drugs in vivo. Here we evaluated humanized mice for their susceptibility to HIV-2 infection and tested a single-pill three drug formulation of anti-retrovirals (NRTIs abacavir and lamivudine, integrase inhibitor dolutegravir) (trade name, Triumeq(R)). Our results showed that hu-mice are susceptible to HIV-2 infection showing persistent viremia and CD4 T cell loss, key hallmarks of AIDS pathogenesis...

Diabetes mellitus affects 9% of the adult population worldwide and the economic burden of the disease is growing exponentially. In type 2 diabetes mellitus (T2DM), when life style interventions fail to achieve treatment targets, oral antidiabetic drugs are prescribed to improve glycemic control. Several new oral antidiabetics have been launched in the last few years, which enlarged the spectrum of available treatment options in T2DM. The present study aimed to examine T2DM treatment patterns in a cohort of 7769 patients recruited from the Diabetes Registry Tyrol (DRT) with at least one visit from 2012-2015...

Information regarding Helicobacter pylori antibiotic resistance in Indonesia was previously inadequate. We assessed antibiotic susceptibility for H. pylori in Indonesia, and determined the association between virulence genes or genetic mutations and antibiotic resistance. We recruited 849 dyspeptic patients who underwent endoscopy in 11 cities in Indonesia. E-test was used to determine the minimum inhibitory concentration of five antibiotics. PCR-based sequencing assessed mutations in 23S rRNA, rdxA, gyrA, gyrB, and virulence genes...

Olivier Sitbon, Sean Gaine
There is a strong rationale for combining therapies to simultaneously target three of the key pathways implicated in the pathogenesis of pulmonary arterial hypertension (PAH). Evidence to support this strategy is growing, and a number of studies have demonstrated that combination therapy, administered as either a sequential or an initial regimen, can improve long-term outcomes in PAH. Dual combination therapy with a phosphodiesterase-5 inhibitor and an endothelin receptor antagonist is the most widely utilised combination regimen...

Breast cancer is the most prevalent cancer in women worldwide. About 15-20% of all breast cancers do not express estrogen receptor, progesterone receptor or HER2 receptor and hence are collectively classified as triple negative breast cancer (TNBC). These tumors are often relatively aggressive when compared to other types of breast cancer, and this issue is compounded by the lack of effective targeted therapy. In our previous phosphoproteomic profiling effort, we identified the non-receptor tyrosine kinase TNK2 as activated in a majority of aggressive TNBC cell lines...
