Identifying a Level of Neutralizing Antibody That Correlates With Protection From Clinical Mumps Disease During a 2017 Mumps Outbreak Among Military Service Members.

Background: In 2017, a mumps outbreak occurred in a US military barracks. Serum collected at service entry was used to compare pre-exposure with presumptive vaccine-induced antibody levels from persons who developed mumps (cases) and potentially exposed persons who did not develop mumps (non-cases). Sufficient information to determine levels of exposure during the outbreak was not available.

Epidemiology and clinical significance of persistent bacteremia in severely burned patients.

Background: The utility of follow-up blood cultures (FUBC) for gram-negative bloodstream infections (BSIs) are controversial due to low rates of positivity. However, recent studies suggest higher rates of positivity in critically ill patients. The utility of FUBC in gram-negative BSI in patients with severe burn injuries is unknown.

Clearance of blood stream infections in patients receiving extracorporeal membrane oxygenation: a retrospective single-center cohort study.

Background: There are limited data on the treatment of blood stream infections (BSIs) in patients receiving extracorporeal membrane oxygenation (ECMO). Current guidance recommends documenting clearance only in fungal and Gram-positive BSIs. This study investigates the incidence and clinical significance of blood stream infections with positive repeat cultures (BSIPRC) in ECMO as well as clinical factors that may predict positive repeat cultures.

Infectious Disease Teleconsultation to the Deployed U.S. Military From 2017-2022.

Introduction: The ADvanced VIrtual Support for OpeRational Forces (ADVISOR) program is a synchronous telemedicine system developed in 2017 to provide 24/7 remote expert support to U.S. Military and NATO clinicians engaged in medical care in austere locations.

Developing Military Doctors: An Institutional Approach to Medical Force Readiness in Graduate Medical Education.

Military physicians are required to not only meet civilian accreditation standards upon completion of their Graduate Medical Education (GME) training programs but also be proficient in the military-unique aspects of their field, including medical care in austere environments and management of combat casualties. They must also be familiar with the administrative and leadership aspects of military medicine, which are often absent from the training curriculum. The San Antonio Uniformed Services Health Education Consortium Military Readiness Committee, by incorporating questions of military relevance into each GME program's mandatory Annual Program Evaluation, identified curricular gaps upon which military readiness training objectives and opportunities were developed.

Sporotrichosis in a U.S. Army Basic Trainee.

Lymphocutaneous sporotrichosis is a mycotic disease caused by traumatic inoculation of the dimorphic fungus Sporothrix schenckii, found ubiquitously in decaying vegetation. The potential for outbreaks, difficulty with timely diagnosis, as well as the prolonged treatment course and recovery from surgical intervention can have a substantial impact on the medical readiness of service members. Treatment with the antifungal therapy of choice, itraconazole, requires close patient monitoring for the duration of treatment for clinical response, drug tolerance, as well as therapeutic drug levels.

Critical Care Education and Skills Validation Course for Internal Medicine Physicians in the Military.

Introduction: Military internist and internal medicine (IM) subspecialist physicians must be prepared to function in both traditional inpatient and outpatient settings, as well as manage critically ill patients within a deployed austere environment. As many critical care procedures are not performed on a routine basis in general IM practice, many active duty IM physicians experience skills degradation and lack confidence in performing these procedures. In order to address this perceived deficiency, the U.

Comparison of A(H3N2) Neutralizing Antibody Responses Elicited by 2018-2019 Season Quadrivalent Influenza Vaccines Derived from Eggs, Cells, and Recombinant Hemagglutinin.

Background: Low vaccine effectiveness against A(H3N2) influenza in seasons with little antigenic drift has been attributed to substitutions in hemagglutinin (HA) acquired during vaccine virus propagation in eggs. Clinical trials comparing recombinant HA vaccine (rHA) and cell-derived inactivated influenza vaccine (IIV) to egg-derived IIVs provide opportunities to assess how egg-adaptive substitutions influence HA immunogenicity.

Methods: Neutralization titers in pre- and postimmunization sera from 133 adults immunized with 1 of 3 types of influenza vaccines in a randomized, open-label trial during the 2018-2019 influenza season were measured against egg- and cell-derived A/Singapore/INFIMH-16-0019/2016-like and circulating A(H3N2) influenza viruses using HA pseudoviruses.

Outcomes of Coronavirus Disease 2019 Drive-Through Screening at an Academic Military Medical Center.

Drive-through coronavirus disease 2019 screening can evaluate large numbers of patients while reducing healthcare exposures and personal protective equipment use. We describe the characteristics of screened individuals as well as drive-through process and outcome measures. Optimal drive-through screening involves rapid turnaround of test results and linkage to follow-up care.

Mumps outbreak and MMR IgG surveillance as a predictor for immunity in military trainees.

In 2017, a mumps outbreak occurred in a barrack holding 249 service members. Suspected cases were evaluated with a combination of mumps IgG, IgM, viral culture, PCR and sequencing. Seven cases were diagnosed in febrile patients presenting with parotitis or orchitis.

Formalization of a Specialty-Specific Military Unique Curriculum: A Joint United States Army and United States Air Force Infectious Disease Fellowship Program.

Introduction: There are many unique aspects to the practice of military Infectious Diseases (ID). San Antonio Uniformed Services Health Consortium Infectious Disease (ID) Fellowship is a combined Army and Air Force active duty program. Program leadership thought ID military unique curriculum (MUC) was well integrated into the program.

Operation United Assistance: infectious disease threats to deployed military personnel.

As part of the international response to control the recent Ebola outbreak in West Africa, the Department of Defense has deployed military personnel to train Liberians to manage the disease and build treatment units and a hospital for health care volunteers. These steps have assisted in providing a robust medical system and augment Ebola diagnostic capability within the affected nations. In order to prepare for the deployment of U.

Spread of vaccinia virus through shaving during military training, Joint Base San Antonio-Lackland, TX, June 2014.

Although naturally occurring smallpox virus was officially declared eradicated in 1980, concern for biological warfare prompted the U.S. Government in 2002 to recommend smallpox vaccination for select individuals.

Variations of CHROMagar Acinetobacter to detect imipenem-resistant Acinetobacter baumannii-calcoaceticus complex.

Background: Acinetobacter baumannii-calcoaceticus complex (ABC) isolates are often multidrug-resistant, including to carbapenems. Chromogenic media can facilitate the rapid detection of Gram-negative bacteria, often with the addition of supplements to a base chromogenic medium to detect resistance. We examined various combinations of available media to detect imipenem resistance among 107 ABC clinical isolates.

Carbapenem susceptibility testing errors using three automated systems, disk diffusion, Etest, and broth microdilution and carbapenem resistance genes in isolates of Acinetobacter baumannii-calcoaceticus complex.

The Acinetobacter baumannii-calcoaceticus complex (ABC) is associated with increasing carbapenem resistance, necessitating accurate resistance testing to maximize therapeutic options. We determined the accuracy of carbapenem antimicrobial susceptibility tests for ABC isolates and surveyed them for genetic determinants of carbapenem resistance. A total of 107 single-patient ABC isolates from blood and wound infections from 2006 to 2008 were evaluated.

Oral antibiotics for infections due to multidrug-resistant Gram-negative organisms.

We determined minimum inhibitory concentrations of rifampicin, nitrofurantoin, amoxicillin-clavulanic acid, and cefdinir, plus a combination of amoxicillin-clavulanic acid and cefdinir by broth microdilution for mainly wound isolates of Escherichia coli and Klebsiella pneumoniae. E. coli and K.
