Gunshot Wounds Cause Significant Mortality, Blood Utilization, and Health Care Costs in the U.S. |
 July 6, 2021
Half
of the world’s civilian firearms are owned by individuals in the United
States. The U.S. also leads all high-income countries for gunshot wound
(GSW)-related deaths, yet little is known about the blood utilization
patterns in GSW victims. Researchers analyzed data from the 2016-2017
National Inpatient Sample and National Emergency Department Sample,
which included 58,815 weighted inpatient hospitalizations from GSWs and
168,315 weighted emergency department visits due to GSWs. [Read More]

Reducing Red Cell Use for Patients with Sickle Cell Disease during a Pandemic |
 June 30, 2021
Since
March 2020, the COVID-19 pandemic has strained blood inventories, so
researchers at one Philadelphia hospital implemented new measures to
reduce blood use in patients with sickle cell disease (SCD). Fifty
patients (mean age, 23.5 years [range: 9 to 44 years]) with SCD
requiring chronic red cell exchanges every 3 to 5 weeks were followed
for 6 months from March 2020 to September 2020 to determine if two new
measures reduced blood usage. [Read More]

Tracking HIV Drug Resistance and Subtypes in Blood Donors |
 June 22, 2021
The
risk of HIV transmission from blood transfusion is low (0.16 to 0.49
per million transfusions) but is still possible due to the viral window
period during which newly acquired infections are not detected by
diagnostic screening methods. In Poland, the frequency of HIV-positive
blood donors and donations per 100,000 was 6.6 and 3.3, respectively.
Therefore, constant hemovigilance is needed to identify
pre-seroconversion infections, but samples can also be used to study HIV
genetic diversity and drug resistance patterns. [Read More]
