#1
Robert E Harris, Jessica Richardson, Rosemary Frasso, Evan D Anderson
BACKGROUND: People who inject drugs (PWID) are at high risk for infectious diseases, skin and soft tissue infections, and overdose. However, these harms are all avoidable when sterile injection equipment, hygienic places to inject, and medical care are accessible. Unfortunately, many PWID in the U.S lack these resources. The most vulnerable are forced to inject in public spaces, where individual risks are high and communal harms are sometimes many. Supervised Injection Facilities (SIFs) are an established intervention for reducing these harms...

REVIEW
N A Nixon, M B Hannouf, S Verma
The cost of cancer drugs continues to escalate with the rapid development and approval of novel therapies, especially over the course of the last decade. In human epidermal growth factor receptor 2 (HER2)-positive breast cancer, the survival benefits gained by new treatments have been undeniably substantial. It is important to assess the financial value of these therapies for decision making at both the societal and individual level. This information is key for managing resources in resource-limited health care systems, while at the same time supporting patient decision-making and conversations between patient and physicians on cost versus benefit...

<p>INTRODUCTION: Dermatologists are becoming more aware of the irritant and allergic potential of laundry detergents that incorporate harsh surfactants and potentially sensitizing ingredients. It is difficult however for the physician to distinguish one laundry detergent from another because the only distinguishing feature advertised tends to be the lack of dyes and fragrances.</p> <p>DESIGN: A new objective method was developed for measuring the harshness of laundry detergents using a three-pronged laboratory testing approach consisting of zein, corneosurfametry, and cytokine testing...

BACKGROUND: Antiretroviral therapy has increased longevity for people living with HIV (PLWH). As a result, PLWH increasingly experience the common diseases of aging and the resources needed to manage these comorbidities are increasing. This paper characterizes the number and types of comorbidities diagnosed among PLWH covered by Medicare and examines how non-HIV comorbidities relate to outpatient, inpatient, and pharmaceutical expenditures. METHODS: The study examined Medicare expenditures for 9767 HIV-positive Californians enrolled in Medicare in 2010 (7208 persons dually covered by Medicare and Medicaid and 2559 with Medicare only)...

Yan Chen, Jin-Yi Zhu, Kwon Ho Hong, David C Mikles, Gunda I Georg, Alex S Goldstein, John K Amory, Ernst Schönbrunn
The ALDH1A subfamily of aldehyde dehydrogenase enzymes are crucial in regulating retinoic acid (RA) signaling and have received attention as potential drug targets. ALDH1A2 is the primary RA-synthesizing enzyme in mammalian spermatogenesis and is therefore considered a viable drug target for male contraceptive development. However, only a small number of ALDH1A2 inhibitors have been reported, and information on the structure of ALDH1A2 was limited to the NAD-liganded enzyme void of substrate or inhibitors. Herein, we describe the mechanism of action of structurally unrelated reversible and irreversible inhibitors of human ALDH1A2 using direct binding studies and X-ray crystallography...

Data drive modern medicine. And our tools to analyze those data are growing ever more powerful. As health data are collected in greater and greater amounts, sophisticated algorithms based on those data can drive medical innovation, improve the process of care, and increase efficiency. Those algorithms, however, vary widely in quality. Some are accurate and powerful, while others may be riddled with errors or based on faulty science. When an opaque algorithm recommends an insulin dose to a diabetic patient, how do we know that dose is correct? Patients, providers, and insurers face substantial difficulties in identifying high-quality algorithms; they lack both expertise and proprietary information...

Hodgkin's lymphoma (HL) is a tumor comprising non-malignant and malignant B-cells. Classical HL expresses CD15+ and CD30+ antigens, and 20 to 40% of patients are CD20+. This antigen is a ligand free protein present in B lymphocyte cells and its function is not well known. Some studies suggest that expression of CD20 may play a major role in Hodgkin's disease pathophysiology and may affect the patients' treatment prognosis, as well as relapse and refractory response. In the past few years, development of monoclonal anti-CD20 antibodies changed drastically the treatment for non-Hodgkin lymphomas in which CD20 is expressed...

According to the U.S. Food and Drug Administration 'the broad scope of digital health includes categories such as mobile health (mHealth), health information technology (IT), wearable devices, telehealth and telemedicine, and personalised medicine, and is used by providers and other stakeholders in their efforts to reduce inefficiencies, improve access, reduce costs, increase quality, and make medicine more personalised for patients (FDA 2016). More recently, Paul Sonier, a digital health strategist and founder of the Linkedin digital health group with more than 40,000 members, defined digital health as 'the convergence of the digital and genomic revolutions with health, healthcare, living, and society' (storyofdigitalhealth...

BACKGROUND: The lower part of the digestive tract includes the large intestine, rectum and anus. Treatment algorithms of cancers in these localities have significant differences in both early and advanced stages. The vast majority of metastatic cases are incurable. A few years ago, it was generally accepted that gastrointestinal tumors are poorly immunogenic and modern immunotherapy would not work in gastrointestinal cancers. The breakthrough has become the recognition of the mismatch repair system (MMR) that affects the microsatellite instability (MSI) and its role in the development of colorectal carcinoma (CRC)...

G protein-coupled receptors (GPCRs) are key players in cell communication and are encoded by the largest family in our genome. As such, GPCRs represent the main targets in drug development programs. Sequence analysis revealed several classes of GPCRs: the class A rhodopsin-like receptors represent the majority, the class B includes the secretin-like and adhesion GPCRs, the class F includes the frizzled receptors, and the class C includes receptors for the main neurotransmitters, glutamate and GABA, and those for sweet and umami taste and calcium receptors...

REVIEW
Gnanendra Shanmugam, Junhyun Jeon
Control of plant diseases is largely dependent on use of agrochemicals. However, there are widening gaps between our knowledge on plant diseases gained from genetic/mechanistic studies and rapid translation of the knowledge into target-oriented development of effective agrochemicals. Here we propose that the time is ripe for computer-aided drug discovery/design (CADD) in molecular plant pathology. CADD has played a pivotal role in development of medically important molecules over the last three decades. Now, explosive increase in information on genome sequences and three dimensional structures of biological molecules, in combination with advances in computational and informational technologies, opens up exciting possibilities for application of CADD in discovery and development of agrochemicals...

Multiple target inhibition has gained considerable interest in combating drug resistance in glioblastoma, however, understanding the molecular mechanisms of crosstalk between signaling pathways and predicting responses of cancer cells to targeted interventions has remained challenging. Despite the significant role attributed to transforming growth factor (TGF)-β family and hepatocyte growth factor (HGF)/c-MET signaling in glioblastoma pathogenesis, their functional interactions have not been well characterized...

Cancer therapeutics frequently lead to symptomatic adverse events (AEs) that can affect treatment tolerability. The National Cancer Institute has developed a patient-reported outcome (PRO) version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) to assess symptomatic AEs by direct patient self-report. While longitudinal assessment of patient-reported symptomatic AEs holds promise to better inform treatment tolerability, using PRO measures to assess symptomatic AEs has raised several regulatory and good clinical practice (GCP) issues among those who conduct cancer clinical trials...

BACKGROUND: Antimicrobial resistance (AMR) is a recognized threat to global public health. Increasing AMR and a dry pipeline of novel antimicrobial drugs have put AMR in the international spotlight. One strategy to combat AMR is to reduce antimicrobial drug consumption. Governments around the world have been experimenting with different policy interventions, such as regulating where antimicrobials can be sold, restricting the use of last-resort antimicrobials, funding AMR stewardship programs, and launching public awareness campaigns...

BACKGROUND: Pompe disease is a rare, progressive, metabolic disease, and the first treatable inheritable muscle disorder. Enzyme replacement therapy (ERT) with alglucosidase alfa is disease specific and the only medicinal product authorized for the treatment of Pompe disease. Costs of ERT are very high as for most orphan drugs. This study investigates the cost-effectiveness of ERT compared to supportive treatment in adult patients with Pompe disease. METHODS: Survival probabilities were estimated from an international observational dataset (n = 283) using a time-dependent Cox model...
