ABSTRACT

Polycythemia vera (PV) is a frequent myeloproliferative disease resulting in excessive red blood cells, white blood cells, and platelets rarely identified in military populations. Increased blood viscosity and platelets can lead to fatal myocardial infarction and stroke. Historically, regimented phlebotomy managed this condition, but modern medicinal advances now are utilized. These immunosuppressive medications are generally incompatible with active-duty service and can lead to medical discharge. Phlebotomy therefore is critical for readiness and health; however, this can be challenging in resource-limited environments, necessitating effective improvisation. We describe an active-duty Soldier with PV symptoms consisting of substernal chest pressure, bilateral lower extremity paresthesias, and persistent pruritic neck rash. He had an elevated hematocrit (Hct) of 47%, necessitating phlebotomy and posing a challenge to his primary care team. The local emergency medicine team employed blood collection bags from whole blood (WB) transfusion kits, including proven volume estimation methods, to routinely draw one unit of blood and effectively manage this condition. This is the first reported case in military literature of PV managed with improvised field resources and techniques.

ABSTRACT



Warm fresh whole-blood transfusion between comrades on the battlefield, also known as "buddy transfusion," has been thrust back into the limelight for several years now. It means drawing blood on the battlefield, once a bleeding soldier needs a transfusion, from one of their uninjured companions and immediately infusing it. It is a lifesaving procedure, effective and hardy. This work aims to answer the main questions that military caregivers might have about it: interest of this procedure, donor and recipient safety, and hemostatic capacity of the blood collected this way.

ABSTRACT

Background: The purpose of this preliminary investigation was to determine the impact of a mental and visual skills training (MVST) program on a high-value target identification and marksmanship (HVTM) task among Special Operations Forces (SOF) Soldiers. Methods: Deidentified archival data for 52 male SOF Operators (age: 31.06 ± 4.10 years) were assessed to determine if differences in performance existed between MVST program users (n = 15) and nonusers (n = 37) on a HVTM task performed immediately after a Special Forces Advanced Urban Combat (SFAUC) stress shoot. Independent-samples t-tests were utilized to determine if significant mean score differences existed between groups on specific shooting elements within the HVTM task. Effect size calculations were also performed to assess the magnitude of differences between groups in each measure of performance. Results: Statistically significant differences in performance were not discovered between MVST users and nonusers on overall score (Score) or any individual elements of the HVTM task. However, small to medium effect sizes (d = 0.305-0.493) were observed between groups in Score, Positive Identification Accuracy, Shot Accuracy, and Kill Shot Score. Conclusion: While inconclusive, these findings suggest the use of a MVST program administered by a trained cognitive performance specialist may have the potential to positively influence HVTM performance. More research using larger sample sizes is required to confirm this supposition.

The JSOM podcast digs deeper into the articles and subjects that matter to our readers. Our podcast hosts, Captains Alex Merkle and Josh Randles, tackle articles from the journal based on merit, interest, and application for operators in the field.

Current Episode

The new Fall 2022 episode of the JSOM podcast is now available on our website and wherever you listen to podcasts.

This podcast episode is focused on research and contributions made by women in service to the military. We start with a review of "Women in US Military History" by Gretchen Garceau-Kragh.

Guest medic HM1(FMF/EXW) Eric Dodson reviews "Active Warfighter Resilience: A Descriptive Analysis" by Nikki Rarczak-Scarborov, et. al.

Finally, we give an objective review of "Operation Blood Rain Phase 2: Evaluating the Effect of Airdrop on Fresh and Stored Whole Blood." The review is complemented with an interview with lead author Dr. (LtCol.) Roselyn Fuentes.
