Introduction: Lyme disease (LD) is an underrated threat to the military that negatively impacts mission readiness. Lyme disease has traditionally been thought to only be a risk in an operational context, where training or deployments are frequently conducted in heavily wooded environments. However, this view diminishes risks posed by many off-duty outdoor recreational activities.

The Gram-negative ESKAPE bacterium has become a pathogen of serious concern due its extensive multi-drug resistance (MDR) profile, widespread incidences of hospital-acquired infections throughout the United States, and high occurrence in wound infections suffered by warfighters serving abroad. Bacteriophage (phage) therapy has received renewed attention as an alternative therapeutic option against recalcitrant bacterial infections, both as multi-phage cocktails and in combination with antibiotics as synergistic pairings. Environmental screening and phage enrichment has yielded three lytic viruses capable of infecting the MDR strain PAO1.

Introduction: Antibiotic-resistant bacteria are a growing threat to civilian and military health today. Although infections were once easily treatable by antibiotics and wound cleaning, the frequent mutation of bacteria has created strains impermeable to antibiotics and physical attack. Bacteria further their pathogenicity because of their ability to form biofilms on wounds, medical devices, and implant surfaces.

Introduction: Long COVID disproportionately affects older adults. Individuals with Long COVID (LC) often experience symptoms that severely impact quality of life, and treatment approaches are still evolving. The Integrative Medical Group Visit (IMGV) model is an evidence-based approach that may be useful to treat patients with LC; however, there is limited evidence describing the experience and/or feasibility of using IMGV for LC treatment, especially among the older adult population.

Injuries to the meniscus are common and can impair physical activities. Bioprinted meniscal tissue offers an attractive alternative to donor tissue for meniscal repair but achieving the strength of native tissue is a challenge. Here we report the development of a tissue engineering bioreactor designed to apply repetitive force which may lead to an increase in the compressive modulus and durability of bioprinted meniscal tissues.

Massive hemorrhaging remains the most common cause of preventable battlefield deaths. Blood used for trauma care requires a robust donation network, capacity for long-term storage, and extensive and accurate testing. Bioengineering technologies could offer a remedy to these constraints in the form of blood substitutes-fluids that could be transfused into patients to provide oxygen, carry away waste, and aid in coagulation-that would be used in prolonged casualty care and in far-forward settings, overcoming the obstacles of distance and time.

Introduction: Known as the "golden hour," survival of most critically injured patients is highly dependent on providing the required treatment within the first hour of injury. Recent technological advances in additive manufacturing (also known as three-dimensional [3D] printing) allow for austere deployment and point-of-care rapid fabrication of a variety of medical supplies, including human tissues and bioactive bandages, in prolonged field care scenarios. In this pilot project, our aim was to investigate the ability to 3D print a range of potential biomedical supplies and solutions in an austere field environment.

Background: The coronavirus disease 2019 (COVID-19) pandemic has resulted in significant upheaval in psychiatric care. Despite survey data collected from psychiatric patients and broad samples of individuals in single countries, there is little quantitative or qualitative data on changes to psychiatric care from the perspective of mental health providers themselves across developing countries.

Methods: To address this gap, we surveyed 27 practicing psychiatrists from Central and Eastern Europe, as well as Africa, the Middle East, and Latin America.

Article Synopsis
  • - The Bronx was a major hotspot for COVID-19 in the U.S., and researchers studied 104 SARS-CoV-2 genomes from March to October 2020 to track how the virus evolved there.
  • - The genomic diversity of the virus in the Bronx reflected trends seen in New York City and the state, but researchers noted changes in mutation prevalence over time.
  • - By analyzing the genomic data, they were able to differentiate between reinfections and ongoing infections in two children, suggesting that targeted genomic monitoring can aid in COVID-19 management.

Disruptive behaviors are a class of predominantly externalizing behaviors that include physical aggression, property destruction, temper outbursts, verbal aggression, and some forms of self-injurious behaviors. Externalizing behaviors are also major components of disruptive, impulse-control and conduct disorders, disruptive mood dysregulation disorder, trauma-related and stressor-related disorders, intermittent explosive disorder, personality disorders, and other neuropsychiatric and neurodevelopmental disorders. Disruptive behaviors and associated disorders are among the most frequent reasons for child behavioral health referrals and are the most common reason for referrals among children with intellectual disabilities.

The clinical outcome of SARS-CoV-2 infection varies widely between individuals. Machine learning models can support decision making in healthcare by assessing fatality risk in patients that do not yet show severe signs of COVID-19. Most predictive models rely on static demographic features and clinical values obtained upon hospitalization.

We document a military patient presenting with a diffuse set of symptoms suggestive of chronic Lyme disease (CLD) and the subsequent empiric treatment and health complications arising therein. The lay medical community, spurred by the internet, has ascribed these diffuse symptoms to various illnesses including CLD without confirmatory serological evidence of any underlying disease. With a growing community of patient advocates, CLD has become an illness with broad and highly generalized list of clinical symptoms and an absence of agreed-upon confirmatory laboratory tests.

Most known SARS-CoV-2 neutralizing antibodies (nAbs), including those approved by the FDA for emergency use, inhibit viral infection by targeting the receptor-binding domain (RBD) of the spike (S) protein. Variants of concern (VOC) carrying mutations in the RBD or other regions of S reduce the effectiveness of many nAbs and vaccines by evading neutralization. Therefore, therapies that are less susceptible to resistance are urgently needed.

The coronavirus disease 2019 (COVID-19) global pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) continues to place an immense burden on societies and health care systems. A key component of COVID-19 control efforts is serological testing to determine the community prevalence of SARS-CoV-2 exposure and quantify individual immune responses to prior SARS-CoV-2 infection or vaccination. Here, we describe a laboratory-developed antibody test that uses readily available research-grade reagents to detect SARS-CoV-2 exposure in patient blood samples with high sensitivity and specificity.
