The continual critical shortage of organs and cells from deceased human donors has stimulated research in the field of cross-species transplantation (xenotransplantation), with the pig selected as the most suitable potential source of organs. Since the US Food and Drug Administration concluded a comprehensive review of xenotransplantation in 2003, considerable progress has been made in the experimental laboratory to improve cell and organ xenograft survival in several pig-to-nonhuman primate systems that offer the best available models to predict clinical outcomes...

Although rare, ALF caused by disseminated HSV infection is associated with high mortality in the neonatal population. This condition is often diagnosed relatively late due to the absence of specific signs. We present a case involving a neonate with ALF submitted to living donor liver transplantation without a prior diagnosis. The patient had no skin or mucosal lesions, and IgM serology was negative for HSV-1 and HSV-2. Immunohistochemical staining of the liver explant was positive for herpes virus infection, and the patient subsequently received antiviral drug treatment, with a good outcome...

BACKGROUND: The three delays model proposes that maternal mortality is associated with delays in: 1) deciding to seek care; 2) reaching the healthcare facility; and 3) receiving care. Previously, the majority of women who died were reported to have experienced type 1 and 2 delays. With increased coverage of healthcare services, we sought to explore the relative contribution of each type of delay. METHOD: 151 maternal deaths were identified during a 12-month reproductive age mortality survey (RAMOS) conducted in Malawi; verbal autopsy and facility-based medical record reviews were conducted to obtain details about the circumstances surrounding each death...

BACKGROUND: In 2016, the US Food and Drug Administration ended the lifetime blood donation deferral for men who have sex with men (MSM) and replaced it with a 1-year deferral period. It is currently unknown how many MSM may meet the new deferral policy and how many are willing to comply with it. STUDY DESIGN AND METHODS: An anonymous survey was shared on MSM-focused social media sites between May and July 2016 and enrolled self-identified American MSM who were at least 18 years old...

Chronic hepatitis C virus (HCV) infection is a leading cause of chronic liver disease. The introduction of direct acting antiviral agents (DAAs) for its treatment represents a major advance in terms of sustained virologic response (SVR) rates and adverse effect profiles. Mechanistically, DAAs inhibit specific HCV non-structural proteins (NS) that are vital for its replication. Boceprevir, telaprevir, simeprevir, asunaprevir, grazoprevir and paritaprevir are NS3/4A inhibitors. Ombitasvir, ledipasvir, daclatasvir, elbasvir and velpatasvir are NS5A inhibitors...

An 8-year-old Mongolian female was diagnosed with acute myeloid leukemia (AML) and treated at a hospital in Mongolia according to the BFM-AML2004 SR protocol. Although complete remission (CR) was achieved, chemotherapy was interrupted because of shortage of drugs. The patient moved to Japan 7 months after diagnosis. Screening for viral infection revealed the presence of hepatitis C virus (HCV) antibody and RNA. At 11 months after initial diagnosis, the patient experienced bone marrow relapse and a RUNX1-RUNX1T1 fusion transcript was detected...

Hepatocyte-like cells (HLCs) are generated from either various human pluripotent stem cells (hPSCs) including induced pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs), or direct cell conversion, mesenchymal stem cells as well as other stem cells like gestational tissues. They provide potential cell sources for biomedical applications. Liver transplantation is the gold standard treatment for the patients with end stage liver disease, but there are many obstacles limiting this process, like insufficient number of donated healthy livers...

Colla corii asini (CCA) is a protein-based traditional Chinese medicine made from donkey skins. Because it has the ability to nourish blood, its demand is increasing rapidly. The shortage of donkey skins increases the risk of the adulteration of CCA products with other animal skins. To ensure the drug efficacy and safety of CCA products, a proteomics technique was applied to reveal proteins in the skins of donkey, horse, cattle, and pig. Species-specific peptides for each animal species were predicted using bioinformatics, and their presence in the skins and gelatin samples was examined by nano-liquid chromatography-tandem mass spectrometry (nano-LC-MS/MS)...

BACKGROUND: Since 1968, China has trained about 1.5 million barefoot doctors in a few years' time to provide basic health services to 0.8 billion rural population. China's Ministry of Health stopped using the term of barefoot doctor in 1985, and changed policy to develop village doctors. Since then, village doctors have kept on playing an irreplaceable role in China's rural health, even though the number of village doctors has fluctuated over the years and they face serious challenges...

Kuwait is located in the Arabian Gulf and has a population of 3.5million. The stem cell transplantation program started in 2000. Autologous peripheral blood stem cell transplantation started first, as it was easier technically to establish. In 2011, the allogeneic program started with focus on acute leukemia and hemoglobinopathies. The success of both programs required teamwork and support of health planners. We are in the process of establishing a bone marrow donor registry. The issue of donor availability and drug shortage remain the two main obstacles for expanding the bone marrow transplantation program...

BACKGROUND: A drug shortage of cisatracurium led to use of atracurium as an alternative neuromuscular blocker (NMB). Cisatracurium may be preferred due to less histamine release and potentially less hypotension. The study purpose is to compare the incidence of hypotension with continuous infusion atracurium to continuous infusion cisatracurium in ICU patients. MATERIALS AND METHODS: This retrospective cohort analysis reviewed 119 ICU patients who received either continuous infusion atracurium (56) or cisatracurium (63)...

Due to an ageing workforce, there is a growing need for greater numbers of nurses to work in areas, such as mental health and alcohol and other drugs (AOD) rehabilitation. These practitioners need to approach their work as 'recovery-oriented practitioners'. Positive experiences and preceptorship during clinical placement in AOD rehabilitation settings might influence students' later career choices and address some of the workforce shortage issues. The aim of the present concurrent, mixed-methods study was to explore students' perceptions of their clinical placement experience in a community-based AOD rehabilitation setting, and to examine attitude, career intention, and satisfaction with the placement...

PURPOSE: We describe trends in U.S. shortages impacting critical care drugs from 2001 to 2016. MATERIALS AND METHODS: Shortages within the scope of critical care were identified using data from the University of Utah Drug Information Services. Shortage characteristics were described using standard descriptive statistics and regression analysis. RESULTS: Of 1969 shortages reported, 1004 (51%) were for drugs used in critical care. New shortages fell from 2001 to 2004, then increased, peaking in 2011 (116)...

While six sigma quality has long been achieved in other industries, it is rarely seen in the pharmaceutical sector. However, consumers and patients deserve six sigma quality pharmaceuticals with minimal risks of shortages or recalls. We propose that the future of pharmaceutical quality is six sigma, meaning that no more than 3.4 defects occur per million opportunities. We discuss the path to get there, including economic drivers, performance-based regulation, Quality by Design, advanced manufacturing technologies, and continuous improvement and operational excellence...

The chronic shortage of human transplants to treat tissue and organ failure has led to the development of xenotransplantation, the transplantation of cells, tissues and organs from another species to human recipients. For a number of reasons, pigs are best suited as donor animals. Successful, routine xenotransplantation would have an enormous impact on the health of the human population, including the young, who sometimes require a replacement organ or islet cells, but especially the elderly, who more often suffer the consequences of organ failure...

BACKGROUND: Vaccines have greatly contributed to the control of vaccine-preventable diseases and to human development. Efforts by many countries to introduce new vaccines are a significant move towards achieving the sustainable development goal for health. However, effective vaccine supply chains that ensure an uninterrupted supply of vaccines are pivotal to attaining universal access to life-saving vaccines and sustainable development. The introduction of new vaccines puts a strain on supply chains; South Africa (SA) is no exception, as there are indications of vaccine stock-outs in clinics...
