Chronic hepatitis B (CHB) has become a treatable and controllable disease. The current nucleos(t)ide analogue (NUC) and pegylated interferon therapies effectively help slow disease progression and reduce the risk of cirrhosis, hepatocellular carcinoma (HCC), and CHB-associated mortality. Long-term viral suppression is easily achievable by NUC therapy, with limited adverse reactions. However, several unmet requirements still exist, including safety and risk-stratified HCC surveillance among patients who received long-term NUC therapy...

The nuclear factor erythroid 2-related factor 2 (Nrf2)-antioxidant response element (ARE) pathway, which induces the production of antioxidant enzymes, is a possible therapeutic target for treating diseases related to oxidative stress. Nrf2 activators often exhibit cytotoxicity due to nonspecific electrophilic reactions with thiol groups. We screened a chemical library to explore Nrf2 activators with a wide safety margin. In at least in vitro experiments, TPNA10168, identified from the library, showed a higher efficacy in Nrf2 activation and a lower cytotoxicity than sulforaphane, a well-known Nrf2 activator...

Polyamidoamine (PAMAM) dendrimers have been investigated as a potential platform for a number of ocular drugs, but only in aqueous solution. In this work we have developed fast dissolving dendrimer-based nanofibers (DNF) as a topical delivery vehicle for the glaucoma drug brimonidine tartrate (BT). The safety and drug release kinetics of these nanofiber mats were evaluated in vitro and in vivo. DNF caused no toxicity at therapeutic levels in cultured cells or ocular irritation in animal tests using a normotensive rat model...

Background: Pig manure utilization and valorization is an important topic with tightening regulations focused on ecological and safety issues. By itself pig manure is a poor substrate for biogas production because of its excessive nitrogen content relative to available organic carbon. Such substrate is alkaline, and methanogenesis can be suppressed, and so additional substrates with high organic carbon must be added. The most promising is straw, which is available from adjacent biogas plant cultures...

As part of the microbial community of meat or as starter cultures, coagulase-negative staphylococci (CNS) serve several essential technological purposes in meat products, such as color development through the reduction of nitrate to nitrite. As the safety of nitrite as an additive has been questioned, we explored the potential of CNS to develop red myoglobin derivatives such as oxymyoglobin and nitrosomyoglobin. Nitrosoheme was extracted to evaluate NO production. This production could be due to a nitric oxide synthase (NOS) activity...

PURPOSE: Radiation therapy is complex and demands high vigilance and precise coordination. Radiation therapists (RTTs) directly deliver radiation and are often the first to discover an error. Yet, few studies have examined the practices of RTTs regarding patient safety. We conducted a national survey to explore the perspectives of RTTs related to quality and safety. METHODS AND MATERIALS: In 2016, an electronic survey was sent to a random sample of 1500 RTTs in the United States...

BACKGROUND: Cutaneous leishmaniasis, caused by a parasitic infection, is considered one of the most serious skin diseases in many low- and middle-income countries. Old World cutaneous leishmaniasis (OWCL) is caused by species found in Africa, Asia, the Middle East, the Mediterranean, and India. The most commonly prescribed treatments are antimonials, but other drugs have been used with varying success. As OWCL tends to heal spontaneously, it is necessary to justify the use of systemic and topical treatments...

Persons of Hispanic/Latino descent may represent different ancestries, ethnic and cultural groups and countries of birth. In the U.S., the Hispanic/Latino population is projected to constitute 29% of the population by 2060. A personalized approach focusing on individual variability in genetics, environment, lifestyle and socioeconomic determinants of health may advance the understanding of some of the major factors contributing to the health disparities experienced by Hispanics/Latinos and other groups in the U...

Liver transplantation is the accepted treatment for patients with acute liver failure and liver-based metabolic disorders. However, donor organ shortage and lifelong need for immunosuppression are the main limitations to liver transplantation. In addition, loss of the native liver as target organ for future gene therapy for metabolic disorders limits the futuristic treatment options, resulting in the need for alternative therapeutic strategies. A potential alternative to liver transplantation is allogeneic hepatocyte transplantation...

RATIONALE, AIMS, AND OBJECTIVES: Previous studies have shown a lack of engagement in the reporting process. There is limited evidence about whether attitudes and behaviours of doctors in the UK towards incident reporting have changed following the events at Mid Staffordshire National Health Service Foundation Trust and the recommendations that followed. We conducted a relatively large survey of doctors, aiming to assess whether doctors recognised incidents and reported them accordingly, along with their behaviours towards reporting and their suggestions of how incident reporting may be improved...

In the context of patient safety, the concept of 'Just Culture' is of the utmost importance. Just Culture implies that quality systems in health care should focus on learning from incidents and errors rather than on blaming individuals; however, the basic assumptions of Just Culture cannot always be upheld in certain specific circumstances. This article focuses on the importance and the limits of Just Culture from a legal perspective.
