Background: Cold-stored low-titer group O whole blood (LTOWB) has become increasingly utilised in both prehospital and in-hospital settings for resuscitation of traumatic haemorrhage. However, implementing the use of LTOWB to ground medical teams has been limited due to logistic challenges.
Methods: In 2022, the Israel Defense Forces (IDF) started using LTOWB in ambulances for the first time in Israel. This report details the initial experience of this rollout and presents a case-series of the first patients treated with LTOWB.
Results: Between January-December 2022, seven trauma patients received LTOWB administered by ground IDF intensive care ambulances after presenting with profound shock. Median time from injury to administration of LTOWB was 35 min. All patients had evidence of severe bleeding upon hospital arrival with six undergoing damage control laparotomy and all but one surviving to discharge.
Conclusions: The implementation of LTOWB in ground medical units is in its early stages, but continued experience may demonstrate its feasibility, safety, and effectiveness in the prehospital setting. Further research is necessary to fully understand the indications, methodology, and benefits of LTOWB in resuscitating severely injured trauma patients in this setting.

Background/purpose: Porcine reproductive and respiratory syndrome virus (PRRSV) is a pathogen with a negative economic impact on the global swine industry. In 2019, a suspected highly pathogenic strain, NPUST-108-929/2019 (108-929), was isolated from a pig farm in Pingtung with an outbreak of high mortality and analyzed. The characteristics of PRRSV 108-929 have barely been studied.

Article Synopsis
- Blood plays a vital role in expeditionary casualty care, with low-titer O whole blood being the preferred universal product, though it is often in short supply.
- The study estimates the potential impact of type-specific whole blood (TSWB) on blood supply based on historical demand during U.S. military operations in Afghanistan and production data from a specific blood distribution center.
- Results indicate that adding type A TSWB could boost whole blood production by 11.1% monthly, with TSWB expected to be used in over 20% of transfusion-required military casualties, suggesting that TSWB could significantly enhance blood availability for future needs.

Background: The use of low titer group O whole blood (LTOWB) for resuscitation of patients with traumatic hemorrhage is becoming increasingly common. Practices regarding the administration of RhD-positive LTOWB to childbearing age females (CBAFs) vary between institutions due to concerns about RhD alloimmunization. This study examined practices related to LTOWB transfusion as they pertain to age and sex.

Article Synopsis
- This study investigates the diagnostic accuracy of indirect immunofluorescence (IIF) for assessing anti-phospholipase A2 receptor antibodies (PLA2R-abs) in patients with inconclusive grey-zone results from enzyme-linked immunosorbent assay (ELISA) related to primary membranous nephropathy (pMN).
- Among 52 patients with grey-zone results, those diagnosed with pMN had significantly higher levels of PLA2R-abs and lower serum creatinine than those with non-pMN conditions.
- The PLA2R-IIF showed a sensitivity of 72% and specificity of 88%, indicating it could enhance diagnostic confidence in grey-zone patients.
