The Amazon River Basin is the largest and the most complex fluvial system in the world. The Brazilian government provides dental and medical care to the riverine populations in this region in part through medical assistance missions, conducted by four hospital ships. The Brazilian Navy invited U.S. Navy medical personnel to join the February 2019 mission aboard Navio de Assistência Hospitalar (NAsH) Carlos Chagas to provide care along the Madeira River. ⋯ This study adds to the limited health data currently available on Brazilian Riverine populations. It demonstrates the effectiveness of the Hospital Assistance missions in providing dental care and documents some unique aspects of Riverine health that warrant further study.

Access to care (ATC) is an important component of providing quality healthcare. Clinics need to be able to accurately measure access; however, patients' reports of access may be different from performance-based data gathered using administrative measures. The purpose of this research is to examine the relationship between ATC administrative data and patient survey results. ⋯ Measuring ATC is a vital step in ensuring the health of patients and the provision of high quality care. Both patient surveys and administrative data are widely used for measuring ATC. This study found statistically significant moderate associations between survey and administrative ATC measures, which remained significant even after controlling for patient characteristics of the facilities. These study results suggest that administrative data can provide an accurate assessment of access; however, survey items can be useful for diagnosing potential issues with access, such as call center scheduling and provider availability. Future studies should explore the gaps in research surrounding best practices at facilities which have high patient experience with access, and look at other survey measures related to access, such as telephone resources and web-based communication programs.

Sustained demand for dermatologic care throughout military medicine, in conjunction with increasing dermatologic provider shortages, has led to increase use of teledermatology in military treatment facilities (MTFs). Initially used to aid in the differentiation of suspicious melanocytic lesions, dermoscopy has found increasing clinical utility in an expanding realm of general dermatologic conditions. We demonstrate the use of synchronous teledermoscopy within a remote MTF by repurposing webcam technology already available at most MTFs. ⋯ Two synchronous teledermatology consultations were completed successfully on patients in MTFs with limited subspecialty capabilities. Both cases, with two lesions of concern per case, had 100% concordance between the on-site and teleconsulted dermatologist. Through observing inter-rater agreements between the on-site and remote dermatologists, this small study demonstrates a novel application of technology readily available at most MTFs.

Hemorrhage is a leading cause of death from potentially survivable civilian and military trauma. As projected conflicts move from settings of tactical and logistical supremacy to hyper-dynamic tactical zones against peer and near-peer adversaries, protracted medical evacuation times are expected. Treatment at the point-of-injury is critical. Although crystalloids like Lactated Ringer's (LR) are ubiquitous, whole blood (WB) is the preferred resuscitation fluid following hemorrhage; however, logistical constraints limit the availability of WB in prehospital settings. Hemoglobin-based oxygen carriers (HBOCs) offer both hemodynamic support and oxygen-carrying capacity while avoiding logistical constraints of WB. We hypothesized that low-volume resuscitation of severe hemorrhagic shock with an HBOC (PEGylated carboxyhemoglobin, [PC]) would improve hemodynamic recovery and 72-hour survival; comparable to WB and superior to LR. ⋯ A single bolus infusion of PC produced superior survival and MAP response compared to LR, which is the standard fluid resuscitant carried by combat medics. PC was not different from WB in terms of survival and MAP, which is encouraging because its reduced logistical constraints make it viable for field deployment. These promising findings warrant further development and investigation of PC as a low-volume, early treatment for hemorrhagic shock in scenarios where blood products may not be available.

A systems perspective was used to describe U.S. Department of Defense (DoD) Global Health Engagement (GHE). This description was based on DoD instructions and higher-level documents related to DoD GHE. A complex system of systems such as health care can benefit from using modeling approaches to help understand the interactions among major components. Models (conceptual, computer-based programs, realistic simulations, or training exercises) can be used to help stakeholders prioritize options and to identify important components and gaps for making performance improvements. Based on the cited documents, we identified major DoD GHE components to create a conceptual model. ⋯ Examining the composition of DoD GHE and creating a defined model can help identify interacting features of this complex system. All of the identified components have been associated with gaps, such as the need for monitoring and measuring tools, and standards. The current state of this system is dynamic and is evolving when confronting gaps. DoD GHE represents an intersection of global health and security in supporting U.S. national security objectives by establishing access and influence with partner nations and among health care-related government and non-government organizations, and as a result, improves the readiness, health, and safety of our military personnel.
