HPV-Related Cancers: A Growing Threat to U.S. Military Health and Readiness

Screening for High-Risk Oral Human Papillomavirus (HPV31, HPV33, HPV35) in a Multi-Racial Pediatric and Adult Clinic Patient Population

Many human papillomavirus (HPV) strains induce cancer in the cervix and the oral cavity. Although high-risk strains including HPV16 and HPV18 are commonly known, additional high-risk strains including HPV31, HPV33, and HPV35 may also induce carcinogenesis, and much less is known about their prevalence. Using an approved protocol, samples from a salivary biorepository were screened to find pediatric and adult samples from a multi-ethnic, university-based patient clinic population. A total of N = 86 samples from the saliva biorepository met the quality and concentration standards and were screened for high-risk HPV. qPCR screening of adult samples revealed n = 10/45 or 22% were HPV31- or HPV33-positive. In addition, a total of n = 9/41 or 21.9% of pediatric samples were either HPV31- or HPV33-positive (or both). No samples harbored HPV35. Most samples were derived from patients within the recommended vaccination or catch-up age range (age 9-45 years). These results demonstrated that a significant percentage of patients harbor additional high-risk HPV strains within the oral cavity, including HPV31 and HPV33. These data support oral healthcare provider recommendations for the newer nine-valent vaccine, which includes both HPV31 and HPV33.

Feasibility and sustainability of a nurse-led intervention to integrate HPV vaccination into medical processing for active-duty Soldiers

To increase Soldiers' access to HPV vaccination, we evaluated the feasibility and sustainability of a nurse-led intervention to integrate HPV vaccination into medical processing procedures for Soldiers. We partnered with nursing staff to introduce HPV vaccine into existing vaccination services at a nurse-led clinic that serves Soldiers at Fort Bragg, North Carolina. In addition to stocking the vaccine, the intervention included training nursing staff (n = 11) strategies for recommending HPV vaccination for Soldiers ages 18-26. We conducted surveys of nursing staff to assess their perspectives on feasibility. Nursing staff tracked HPV vaccine uptake among Soldiers for 4 weeks post-training to assess adoption and again for 2 weeks at 4-month follow-up to assess sustainability. We assessed delivery cost as the cost of personnel time, vaccine doses, and other materials during the initial 4-week intervention period. Nursing staff agreed that recommending HPV vaccination fit in with medical processing procedures (mean = 4.6 of 5.0). Of the 516 Soldiers offered HPV vaccine in the 4 weeks following the training, 198 (38%) accepted and received the vaccine. Soldier ages 18-20 more often accepted HPV vaccination than older Soldier ages 21-26 (46% versus 32%, p < .01). Vaccine uptake was similar at follow-up, with 98 of 230 eligible Soldiers (43%) receiving HPV vaccine. The total delivery cost was $12,737, with an average cost per vaccine dose delivered of $64. Our findings suggest that training nursing staff to recommend and administer HPV vaccinations to Soldiers is feasible and warrants wider-scale testing as a strategy to protect soldiers from HPV-attributable cancers.

A Historical Review of Military Medical Strategies for Fighting Infectious Diseases: From Battlefields to Global Health

The environmental conditions generated by war and characterized by poverty, undernutrition, stress, difficult access to safe water and food as well as lack of environmental and personal hygiene favor the spread of many infectious diseases. Epidemic typhus, plague, malaria, cholera, typhoid fever, hepatitis, tetanus, and smallpox have nearly constantly accompanied wars, frequently deeply conditioning the outcome of battles/wars more than weapons and military strategy. At the end of the nineteenth century, with the birth of bacteriology, military medical researchers in Germany, the United Kingdom, and France were active in discovering the etiological agents of some diseases and in developing preventive vaccines. Emil von Behring, Ronald Ross and Charles Laveran, who were or served as military physicians, won the first, the second, and the seventh Nobel Prize for Physiology or Medicine for discovering passive anti-diphtheria/tetanus immunotherapy and for identifying mosquito Anopheline as a malaria vector and plasmodium as its etiological agent, respectively. Meanwhile, Major Walter Reed in the United States of America discovered the mosquito vector of yellow fever, thus paving the way for its prevention by vector control. In this work, the military relevance of some vaccine-preventable and non-vaccine-preventable infectious diseases, as well as of biological weapons, and the military contributions to their control will be described. Currently, the civil-military medical collaboration is getting closer and becoming interdependent, from research and development for the prevention of infectious diseases to disasters and emergencies management, as recently demonstrated in Ebola and Zika outbreaks and the COVID-19 pandemic, even with the high biocontainment aeromedical evacuation, in a sort of global health diplomacy.
