A vaccine to prevent infection and disease caused by Plasmodium vivax is needed both to reduce the morbidity caused by this parasite and as a key component in efforts to eradicate malaria worldwide. Vivax malaria protein 1 (VMP001), a novel chimeric protein that incorporates the amino- and carboxy- terminal regions of the circumsporozoite protein (CSP) and a truncated repeat region that contains repeat sequences from both the VK210 (type 1) and the VK247 (type 2) parasites, was developed as a vaccine candidate for global use.
We conducted a first-in-human Phase 1 dose escalation vaccine study with controlled human malaria infection (CHMI) of VMP001 formulated in the GSK Adjuvant System AS01B. A total of 30 volunteers divided into 3 groups (10 per group) were given 3 intramuscular injections of 15 μg, 30 μg, or 60 μg respectively of VMP001, all formulated in 500 μL of AS01B at each immunization. All vaccinated volunteers participated in a P. vivax CHMI 14 days following the third immunization. Six non-vaccinated subjects served as infectivity controls.
The vaccine was shown to be well tolerated and immunogenic. All volunteers generated robust humoral and cellular immune responses to the vaccine antigen. Vaccination did not induce sterile protection; however, a small but significant delay in time to parasitemia was seen in 59% of vaccinated subjects compared to the control group. An association was identified between levels of anti-type 1 repeat antibodies and prepatent period.
This trial was the first to assess the efficacy of a P. vivax CSP vaccine candidate by CHMI. The association of type 1 repeat-specific antibody responses with delay in the prepatency period suggests that augmenting the immune responses to this domain may improve strain-specific vaccine efficacy. The availability of a P. vivax CHMI model will accelerate the process of P. vivax vaccine development, allowing better selection of candidate vaccines for advancement to field trials.

Q fever, a zoonosis caused by Coxiella burnetii , is seen throughout the world. Recent reports suggest that its incidence in the United States is increasing, with more than 30 cases reported in the US military. The disease has many acute and chronic manifestations. Endocarditis is the most common form of chronic disease, and recent studies have led to substantial changes in the approach to its diagnosis and treatment. Military and civilian health care professionals need to consider Q fever when evaluating patients with appropriate geographic exposures and clinical presentations to prevent delays in diagnosis and treatment.

2023
Background
The importance of effective leadership for improving patient care and physician well-being is gaining increased attention in medicine. Despite this, few residency programs have formalized education on leadership in medicine. The most effective ways to train graduate medical education (GME) trainees in leadership are unclear.
Methods
Our large internal medicine residency program implemented a book club to develop leadership skills in residency. Through independent reading of the selected book and resident-led small group discussions, we facilitated dialogue on the challenges of leading effectively.
Results
A survey-based curricular evaluation demonstrated that 61% of respondents felt that the book club influenced their thoughts about leadership and that 66% of participants would recommend the book club to other residency programs. Lack of time was the main barrier to participation while addition of complementary media or alternative book formats were identified as possible solutions to increase engagement.
Conclusions
Leadership book clubs are a practical and effective way to teach leadership during residency. More research is needed to identify the best formats for book club discussion and to develop additional tools to foster future physician leaders.

Faculty Development
2020
Academic leadership in undergraduate and graduate medical education requires a specific set of leadership and managerial skills that are unique to academic leadership positions. While leadership development training programs exist for traditional leadership roles such as department chairs, executives, and deans, there are fewer models of leadership training specifically geared for academic leadership positions such as program and clerkship directors, and designated institutional officials. There are academic programs at the national level, but there is sparse literature on the specific decisions required to create such programs locally. With growing regulatory and accreditation requirements as well as the challenges of balancing the clinical and educational missions, effective leadership is needed across the spectrum of academic medicine. To meet this need for the military health care system in the United States, we used Kern’s six-step framework for curriculum development to create a 1-week academic leadership course. This paper describes the process of development, implementation, outcomes, and lessons learned following the initial 3 years of courses. Specific discussions regarding who to train, which faculty to use, content, and other elements of course design are reviewed. The course and process outlined in the paper offer a model for other organizations desiring to establish an academic leadership course.

Developing a Physician Leadership Program Through Inter-Organizational Collaboration
2025
Effective physician leadership is an essential component in modern healthcare, but medical education often lacks accessible, formal leadership training for the physicians who will move into these roles. We describe the development, implementation, and evaluation of a local leadership program developed at our institute in partnership with a local university that can be used as a template for other healthcare systems. The Medicine Institute's leadership team at Allegheny Health Network partnered with a local university to develop a year-long faculty physician leadership program tailored to minimize travel and associated costs while focusing on concepts of clinician leadership, conflict resolution, healthcare finance, and organizational culture. Participants were selected after a formal application process and completed pre- and post-course assignments and surveys. Data analysis included Wilcoxon signed-rank tests and paired t-tests, along with a qualitative analysis of key insights obtained from free-text comments. Fourteen faculty members participated in the leadership program, spread over a one- year period (January 1, 2024 through January 15, 2025). Individual and composite scores showed a statistically significant increase in self-reported awareness, confidence, and understanding after program completion (p < 0.05). Key insights gathered from the free-text comments indicated participants had increased self-awareness, enhanced leadership skills, valuable networking, immediate applicability of learned concepts, heightened motivation, and a strong desire for continued engagement. The program successfully reduced some of the common barriers to participation in existing leadership programs such as geographic accessibility, travel related costs, and time constraints. The partnership between two institutions supported improvements in leadership competencies and provided a framework for ongoing professional development, which may serve as a useful model for other organizations seeking to develop physician leaders. Our results support ongoing investment in physician leadership development programs that ensure a steady pipeline of physician leaders in healthcare systems.

Factors Influencing Selection of Infectious Diseases Training for Military Internal Medicine Residents
2018
Similar factors affect career choice among military internal medicine residents and their civilian counterparts, including mentorship, learning style, and salary. Recruitment strategies for infectious (ID) diseases physicians should focus on residency opportunities, considering reasons for continued interest in military ID.
Abstract
Background
Applications to infectious diseases fellowships have declined nationally; however, the military has not experienced this trend. In the past 6 years, 3 US military programs had 58 applicants for 52 positions. This study examines military resident perceptions to identify potential differences in factors influencing career choice, compared with published data from a nationwide cohort.
Methods
An existing survey tool was adapted to include questions unique to the training and practice of military medicine. Program directors from 11 military internal medicine residencies were asked to distribute survey links to their graduating residents from December 2016 to January 2017. Data were categorized by ID interest.
Result
The response rate was 51% (n = 68). Of respondents, 7% were ID applicants, 40% considered ID but reconsidered, and 53% were uninterested. Of those who considered ID, 73% changed their mind in their second and third postgraduate years and cited salary (22%), lack of procedures (18%), and training length (18%) as primary deterrents to choosing ID. Active learning styles were used more frequently by ID applicants to learn ID concepts than by those who considered or were uninterested in ID (P = .02).
Conclusions
Despite differences in the context of training and practice among military trainees compared with civilian colleagues, residents cited similar factors affecting career choice. Interest in global health was higher in this cohort. Salary continues to be identified as a deterrent to choosing ID. Differences between military and civilian residents' desire to pursue ID fellowship are likely explained by additional unmeasured factors deserving further study.

Recognizing the Importance of Leadership: A Recent Graduate Develops a Corpsman
2018
There is a growing interest in leadership development within the field of medicine both within the military and the larger medical community. Recognition of the importance of leadership training during graduate medical education has grown, but many residents and faculty still argue that residency training should focus on clinical skills and medical knowledge. Most graduates of training programs in the military quickly find themselves in formal leadership positions or they must informally lead in their clinical practice. As these new graduates enter practice, they quickly realize the need to be able to effectively lead. In order to highlight some of the leadership challenges that junior military physicians face, Military Medicine is starting a new column called \"Leadership Lessons from the Field.\" This article is the first in the series and discusses a recent graduate's experience in dealing with an underperforming corpsman. The article reviews the importance of emotional intelligence, feedback, and goal setting.

Despite calls for greater physician leadership, few medical schools, and graduate medical education programs provide explicit training on the knowledge, skills, and attitudes necessary to be an effective physician leader. Rather, most leaders develop through what has been labeled \"accidental leadership.\" A survey was conducted at Walter Reed to define the current status of leadership development and determine what learners and faculty perceived as key components of a leadership curriculum.
A branching survey was developed for residents and faculty to assess the perceived need for a graduate medical education leadership curriculum. The questionnaire was designed using survey best practices and established validity through subject matter expert reviews and cognitive interviewing. The survey instrument assessed the presence of a current leadership curriculum being conducted by each department, the perceived need for a leadership curriculum for physician leaders, the topics that needed to be included, and the format and timing of the curriculum. Administered using an online/web-based survey format, all 2,041 house staff and educators at Walter Reed were invited to participate in the survey. Descriptive statistics were conducted using SPSS (version 22).
The survey response rate was 20.6% (421/2,041). Only 17% (63/266) of respondents stated that their program had a formal leadership curriculum. Trainees ranked their current leadership abilities as slightly better than moderately effective (3.22 on a 5-point effectiveness scale). Trainee and faculty availability were ranked as the most likely barrier to implementation. Topics considered significantly important (on a 5-point effectiveness scale) were conflict resolution (4.1), how to motivate a subordinate (4.0), and how to implement change (4.0). Respondents ranked the following strategies highest in perceived effectiveness on a 5-point scale (with 3 representing moderate effectiveness): leadership case studies (3.3) and small group exercises (3.2). Online power points were reported as only slightly effective (1.9). Free text comments suggest that incorporating current duties, a mentoring and coaching component, and project based would be valuable to the curriculum.
Few training programs at Walter Reed have a dedicated leadership curriculum. The survey data provide important information for programs considering implementing a leadership development curriculum in terms of content and delivery.
