BACKGROUND: Long-term success of HIV antiretroviral therapy requires near-perfect adherence, maintained throughout one's lifetime. However, perceptions towards ART and patterns of adherence may change during the life course. We assessed challenges to long-term adherence in adolescents and adults in three regional HIV treatment centers in Uganda. METHODS: We conducted 24 in-depth interviews and 2 focus group discussions with a total of 33 health-care providers and expert clients (HIV patients on long-term ART who assist with adherence support of fellow patients)...

Shortages and sudden price increases of certain drugs may both occur emergently, with little to no warning, and they can have a dramatic impact on patient care. Little data are available linking drug shortages and price increases. Many of the same characteristics that may make medications susceptible to shortages can also place them at risk for sudden price increases. These characteristics include unapproved drugs, off-patent sole-source medications, and infrequently used medications. We reviewed drug shortage data from the University of Utah Drug Information Service to demonstrate how frequently these characteristics occurred and resulted in higher drug prices...

Despite the substantial body of research investigating the use of liposomes, niosomes and other bilayer vesicles for drug delivery, the translation of these systems into licensed products remains limited. Indeed, recent shortages in the supply of liposomal products demonstrate the need for new scalable production methods for liposomes. Therefore, the aim of our research has been to consider the application of microfluidics in the manufacture of liposomes containing either or both a water soluble and a lipid soluble drug to promote co-delivery of drugs...

BACKGROUND: Drug shortages require clinical teams to decide how to allocate drugs in limited supply among their patients. Ethical frameworks are invaluable for promoting rational approaches to drug distribution, but gaps remain between ethical theory and clinical application. The goal of this work was to explore how decision modeling could supplement ethical frameworks to inform drug distribution from the perspective of a clinical team. PROCEDURE: We created a hypothetical pediatric oncology clinic with a limited supply of 50,000 mg of methotrexate (MTX) and 21 patients due for treatment on one of six regimens...

OBJECTIVE: Using data from four public-sector clinics in South Africa we sought to investigate provider and patient level outcomes, to understand how the 2012 tenofovir stock shortage affected the HIV care and monitoring of ART patients. METHODS: Prospective cohort analysis of ART-naïve, non-pregnant, HIV-infected patients >18 years initiating first-line ART between July 1, 2011-March 31, 2013. Linear regression was used for all outcomes (number of ART initiates, days between pharmacy visits, transfers, single drug substitutions, treatment interruptions, missed pharmacy visits, loss to follow-up and elevated viral load)...

Influenza A viruses (IAVs) remain serious threats to public health because of the shortage of effective means of control. Developing more effective virus control modalities requires better understanding of virus-host interactions. It has previously been shown that IAV induces the production of kynurenine, which suppresses T-cell responses, enhances pain hypersensitivity and disturbs behaviour in infected animals. However, the regulation of kynurenine biosynthesis during IAV infection remains elusive. Here we showed that IAV infection induced expression of interferons (IFNs), which upregulated production of indoleamine-2,3-dioxygenase (IDO1), which catalysed the kynurenine biosynthesis...

Drugs under development can cause unpredicted toxicity in humans due to differential drug responsiveness between humans and other disease models, resulting in clinical trial failures. Human induced pluripotent stem cells (iPSCs) are expected to represent a useful tool for toxicity testing. However, among many assays, appropriate cellular assays for predicting neurotoxicity in an iPSC-based model are still uncertain. Here, we generated neurons from iPSCs of Charcot-Marie-Tooth disease (CMT) patients, who are sensitive to anti-cancer drugs and present with the adverse reaction of neuropathy, and analyzed cellular phenotypes...

The 2015 represent the deadline for the global tuberculosis (TB) targets set through the Millennium Development Goals (MDG). From 2016 and onward, new goals were set to end the global TB epidemic via implementing new campaign entitled "the End TB Strategy". The major hurdle to end TB epidemic in several parts of the world is the emergence and spread of drug resistant Mycobacterium tuberculosis (MTB) strains. The better understanding of the actual global burden of drug resistant tuberculosis would feed into better implementing the End TB Strategy...

Wilson's disease (WD) is characterized by the inability to excrete copper (Cu) from the body with progressive tissue injury, especially in liver and brain. The molecular defect in WD concerns mutations in ATP7B gene leading to loss of Cu transport from the hepatocyte to the bile canaliculus. While drugs, e.g., Cu chelators, have been available for several decades, these must be taken lifelong, which can be difficult due to issues of compliance or side effects. Many individuals may require liver transplantation, which can also be difficult due to donor organ shortages...

BACKGROUND: Health systems often fail to use evidence in clinical practice. In maternal and perinatal health, the majority of maternal, fetal and newborn mortality is preventable through implementing effective interventions. To meet this challenge, WHO's Department of Reproductive Health and Research partnered with the Knowledge Translation Program at St. Michael's Hospital (SMH), University of Toronto, Canada to establish a collaboration on knowledge translation (KT) in maternal and perinatal health, called the GREAT Network (Guideline-driven, Research priorities, Evidence synthesis, Application of evidence, and Transfer of knowledge)...

BACKGROUND: About 2-3 % of the population participates in blood donation programmes. Each whole blood donation or ten apheresis donations cause a loss of 200-250 mg of iron. As a result, one of the most common risks of regular blood donors is iron deficiency. Although this has been known for decades, in most countries, iron status is currently not assessed or treated in this population. Premenopausal women are particularly affected, as they have lower iron reserves and higher daily requirements...

Hepatocellular carcinoma (HCC) is the most common primary liver malignancy and is a leading cause of cancer-related death worldwide. In the United States, HCC is the ninth leading cause of cancer deaths. Despite advances in prevention techniques, screening, and new technologies in both diagnosis and treatment, incidence and mortality continue to rise. Cirrhosis remains the most important risk factor for the development of HCC regardless of etiology. Hepatitis B and C are independent risk factors for the development of cirrhosis...

Allogeneic islet transplantation has become a viable option for the treatment of unstable type 1 diabetes; however, donor shortage and the necessity for immunosuppressive drugs are two major drawbacks of this treatment. Microencapsulated porcine islets can solve both of these drawbacks, and clinical trials have been conducted. Previous clinical trials demonstrated the safety and marginal efficacy of this treatment; therefore, it is necessary to improve its efficacy. The production of microencapsulated porcine islets consists of pancreas procurement, islet isolation, and microencapsulation...
