The article presents a clinical case of peculiarities of clinical manifestations, diagnostic and therapeutic approaches of undiagnosed chronic myeloproliferative disease, on the background of which Budd-Chiari syndrome (BCS) developed. The results of clinical course, examination, and treatment of a patient with BCS as a manifestation of the hidden course of primary myelofibrosis with the presence of somatic mutation (V617F) in Janus-tyrosine kinase-2 (JAK2) gene in myeloid cells are presented. Standard clinical and laboratory examinations, and cytomorphologic and histologic examination of bone marrow were used. ⋯ Seven years after the installation of 4 transjugular intrahepatic portosystemic shunts, the patient's condition remains satisfactory. The uniqueness of this clinical case lies in the presence of 2 serious diseases at the same time: myeloproliferative pathology (primary myelofibrosis) JAK2-positive variant and BCS. Timely diagnosis of both hematological diseases and their complication in the form of hepatic vein thrombosis with fulminant cytolytic syndrome allowed timely prescription of adequate treatment with a good clinical response.

Recruit training is the initial entry for enlisted personnel in the military. The Services execute gender-integrated recruit training differently. The U.S. Marine Corps (USMC) maintains same-gender platoons led by same-gender drill instructors in integrated companies; further integration occurs at select training events. The other Services train recruits in gender-integrated units with mixed-gender drill instructor teams. We examine recruits' experiences and perceptions of gender integration at recruit training, their desired level of integration, and preferences for increasing gender integration, comparing by Service and gender. ⋯ This study provided an opportunity to examine recruit perspectives on gender-integrated training. Services valuing opposite-gender instructor exposure in recruit training must ensure that male recruits are being taught and led by female instructors given disproportionate demographics. Recruits who experienced integrated training were more supportive of integration, indicating that this experience may increase their support for gender-integrated training units and environments. Today's recruits understand that they are entering gender-integrated working environments, and our results indicate that they expect recruit training to mirror that reality.

Recruit training is designed to transform civilians into physically fit military service members, who embody their service's core values and possess military discipline and skills. At the time this research began, the U.S. Marine Corps (USMC) remained the only service that segregated recruits by gender at the lowest unit level (e.g., platoon) and employed gender-segregated drill instructor teams. USMC's Marine Corps Recruit Depots (MCRD) must comply with a 2020 Congressional Mandate to not segregate training by gender in Parris Island by 2025 and San Diego by 2028. In turn, USMC requested an independent scientific study to analyze current approaches to gender integration at recruit training to propose alternate models and other policy recommendations that increase gender integration while maintaining current USMC standards. The Marine Corps is currently evaluating alternate models and recommendations to optimize entry-level training. This article outlines considerations for choosing the optimal research study design, research methods, and types of data collected in a study intended to provide policy recommendations on gender-integrated recruit training for the USMC. ⋯ This multidisciplinary research approach provided a comprehensive picture of the current USMC recruit training models. The research team captured multiple perspectives and data points for analysis through an expansive view on gender integration across all services, by interacting with participants at all levels of the institutions in varied ways. The information and data gathered enabled the research team to establish objective, data-driven alternate models, and recommendations for enhancing gender integration at recruit training for the USMC.

Musculoskeletal injuries (MSIs) occur frequently in military personnel. U.S. Marine Corps (USMC) recruits participate in an intense 13-week training program designed to transform civilians into basically trained Marines, during which they are susceptible to MSIs. Previous injury epidemiology research with USMC recruits was conducted in a non-gender-integrated training. Data for the current study were derived from a larger study, the USMC Gender-Integrated Recruit Training study, that was initiated to provide data-driven recommendations for gender integration during USMC recruit training. The purpose of the current analysis was to describe the unique profile of MSIs during USMC recruit training and compare MSIs between female and male recruits in gender-integrated training. ⋯ This was the first study to assess the burden of MSIs concurrently among female and male USMC recruits in gender-integrated training. MSIs, especially those affecting the lower extremity, continue to occur frequently in this population. Female recruits are more susceptible to MSIs during USMC recruit training compared to male recruits and are especially prone to hip MSIs. Future research should focus on identifying modifiable risk factors for MSIs in this population, with a focus on reducing lower-extremity MSIs in all recruits and hip MSIs in female recruits.

The 2020 National Defense Authorization Act mandated that the Marine Corps not segregate recruit training by gender. This Military Medicine supplement details an independent academic study contracted by the Marine Corps Training and Education Command to inform the Marine Corps' future approaches to gender integration at recruit training. ⋯ A feasible path lies ahead to enhance the Corps' legacy of success. This special issue supports the Marine Corps Training and Education Command 2030 posture statement for leveraging science and technology for policy and doctrine to prepare and modernize the Marine Corps for the future operating environment.
