BACKGROUND: Infection with the Hepatitis B virus (HBV) continues to be one of the leading healthcare issues in Pakistan, affecting over 6 million people. The existence of HBsAg mutants is well documented in many countries. In Pakistan, HBV screening in the majority of the blood banks is performed by Rapid Detection Devices or ELISA tests. These tests are designed to detect HBsAg, but may not detect the mutant HBsAg. Failure to detect the HBsAg mutant may result in the transmission of HBV infection from donor to recipient...

REVIEW
Olivier Garraud
Contrary to what is generally considered, plasma for direct therapeutic use is all but "standard" and can be made using a multitude of variable processes differing from one preparation to another; in sum, those changes make the final component inhomogeneous especially within inter-blood bank comparisons. The variability is further multiplied by the donors' genetic polymorphisms. This is rarely addressed in the clinical trials and meta analyses, though this may have impact on clinical outcome in patients. This short review encompasses the variability parameters in the processing of therapeutic plasma and advocates for novel, prospective, trials to assess which type of plasma is the most beneficial to patients in need, as this type may differ depending on the patients' pathological condition...

BACKGROUND: 18% of the world's population lives in India, and many states of India have populations similar to those of large countries. Action to effectively improve population health in India requires availability of reliable and comprehensive state-level estimates of disease burden and risk factors over time. Such comprehensive estimates have not been available so far for all major diseases and risk factors. Thus, we aimed to estimate the disease burden and risk factors in every state of India as part of the Global Burden of Disease (GBD) Study 2016...

Introduction: Placental-Cadherin (CDH3) is a cell adhesion molecule vital to cellular localization and tissue integrity. It is highly expressed in the placenta (PLC)and is overexpressed by many types of cancer. P-cadherin levels in colorectal cancer (CRC) remains poorly characterized. This study's purpose was to determine P-cadherin expression in CRC and normal tissues and to assess plasma CDH3 levels in order to determine the relationship, if any, between cancer stage, P-cadherin expression and plasma CDH3 levels...

BACKGROUND: Platelet transfusion therapy poses many challenges in veterinary clinical practice. Lack of readily available blood donors, short shelf-life, and inability to administer a sufficient number of platelets to meet a dog's transfusion need are the major difficulties encountered. Platelet additive solutions are already in use at American and European human blood banks, showing to be a realistic alternative. This study compares the in vitro platelet function in plasma, Composol, or SSP+ during storage for 13 days...

Although uncommon, stroke can be a catastrophic inpatient complication for patients with hip fractures. The current study determines the incidence of inpatient stroke after hip fractures in elderly patients, identifies risk factors associated with such strokes, and determines the association of stroke with short-term inpatient outcomes. A retrospective review of all patients aged 65 years or older with isolated hip fractures in the 2011 and 2012 National Trauma Data Bank was conducted. A total of 37,584 patients met inclusion criteria...

Outbreaks caused by Dengue, Zika and Chikungunya viruses can spread rapidly in immunologically naïve populations. By analysing 92 newly generated viral genome sequences from blood donors and recipients, we assess the dynamics of dengue virus serotype 4 during the 2012 outbreak in Rio de Janeiro. Phylogenetic analysis indicates that the outbreak was caused by genotype II, although two isolates of genotype I were also detected for the first time in Rio de Janeiro. Evolutionary analysis and modelling estimates are congruent, indicating a reproduction number above 1 between January and June, and at least two thirds of infections being unnoticed...

DNA sequence-based typing at the HLA-A, -B, -C, -DPB1, -DQA1, -DQB1, and -DRB1 loci was performed on anonymized samples provided by 339 healthy adult blood bank donors in Managua, Nicaragua. The purpose of the study was to characterize allele frequencies in the local population to support studies of T cell immunity against pathogens, including Dengue virus. Deviations from Hardy Weinberg proportions were detected for all class II loci (HLA-DPB1, -DQA1, -DQB1 and -DRB1), and at the class I C locus, but not at the class I A and B loci...

A new blood bank system was established in our trauma bay, which allowed immediate utilization of uncross-matched type O packed red blood cells (UORBCs). We investigated the efficacy of UORBC compared to that of the ABO type-specific packed red blood cells (ABO RBCs) from before the bank was installed. From March 2016 to February 2017, data from trauma patients who received UORBCs in the trauma bay were compared with those of trauma patients who received ABO RBCs from January 2013 to December 2015. Propensity matching was used to overcome retrospective bias...

The government of India has heavily promoted research and development in regenerative medicine together with domestic innovation and business development initiatives. Together, these promise a revolution in healthcare and public empowerment in India. Several national and transnational linkages have emerged to develop innovative capacity, most prominently in stem cell and cord blood banking, as well as in gene therapy, tissue engineering, biomaterials and 3D printing. However, challenges remain of achieving regulatory oversight, viable outputs and equitable impacts...

The Australian Government's National Bowel Cancer Screening Program (NBCSP) was introduced in 2006 to provide free home-based immunochemical faecal occult blood test (iFOBT) to eligible Australians turning 55 and 65years in that year. With the gradual inclusion of additional age cohorts, the rollout of the NBCSP is being implemented in the context of a degree of opportunistic screening being provided through primary care physicians. This study investigated factors associated with ever-uptake of the NBCSP and of any CRC screening using questionnaire data from Australians aged ≥45years enrolled in the 45 and Up Study...

BACKGROUND: Recent results show a protective effect of tranexamic acid on death due to bleeding in patients with postpartum hemorrhage in low- and middle-resource countries. We quantify the association between early administration of tranexamic acid compared to late or no administration and severe acute maternal morbidity and blood loss among women suffering from persistent severe postpartum hemorrhage in a high-income country. METHODS AND FINDINGS: We performed a nationwide retrospective cohort study in 61 hospitals in the Netherlands...

Injuries to the central nervous system can affect the blood-brain barrier (BBB), including disruption and influencing peptide transport across the BBB. Pituitary adenylate cyclase-activating polypeptide 38 (PACAP38) is a potent neurotrophic and neuroprotective peptide currently being investigated for its therapeutic role following injury to the central nervous system and can cross the BBB in a saturable manner. The goal of the current study was to investigate for the first time PACAP38 uptake by the brain following traumatic brain injury (TBI)...

William A Banks, Andrej Kovac, Yoichi Morofuji
Crosstalk among brain endothelial cells (BECs), pericytes, and astrocytes occurs by way of soluble factors, including cytokines. Here, we studied cytokine secretion from both mouse BEC monocultures and tri-cultured with pericytes and astrocytes. Four cytokines were constitutively secreted by BEC monolayers, 12 by LPS-stimulated BECs, 10 by tri-cultures, and 14 by LPS-stimulated tri-cultures. Cytokine levels were generally higher with either LPS stimulation or tri-culture when compared to monocultures and highest in tri-cultures stimulated by LPS...
