Health Care Utilization During the First 5½ Years of Authorized Service by Transgender U.S. Service Members (2016-2021).

Purpose: This study examined the utilization of gender-affirming health care by active-duty service members during the initial 5½ years that transgender and gender-diverse (TGD) individuals were authorized to serve in the U.S. military. The aim of this study was to inform policy discussions regarding inclusion of TGD individuals in the military. Methods: We conducted a retrospective cohort study using administrative health care data from the Military Data Repository (MDR). We assessed the association of demographic factors with the utilization of gender-affirming medical and surgical care. We calculated the incidence rate of initial TGD-related encounters and new prescriptions for gender-affirming hormones among Defense Department Service members between July 2016 and December 2021. Results: We identified 2481 service members with an initial health care encounter with an associated TGD-related diagnosis. More than half (53%) of these service members started gender-affirming hormones, and 14% underwent gender-affirming surgery. Mastectomies and hysterectomies accounted for more than 70% of surgeries. Service members made 3.22 initial encounters with a TGD-related diagnosis per 10,000 service members per year, with an overrepresentation of service members who were designated female in the MDR (8.62), junior enlisted (4.98), and young (4.64). Individuals designated female in the MRD comprised 17% of all service members but accounted for 46% of initial encounters, 51% of new prescriptions, and 73% of surgeries. Conclusion: The study revealed a higher-than-expected number of service members seeking gender-affirming care, particularly among service members designated female in the MDR. Military Health System clinicians provided most of this care, which may mitigate the cost of delivering this essential medical care.

Real-World Pitfalls of Analyzing Real-World Data: A Cautionary Note and Path Forward.

PURPOSE: Real-world data (RWD) are pervasive in oncology research and offer insights into clinical trends and patient outcomes. However, RWD have shortcomings, making them prone to pitfalls during survival analyses. The American Society of Clinical Oncology (ASCO) CancerLinQ Discovery (CLQD) multiple myeloma (MM) data set was used to demonstrate some common pitfalls when analyzing survival from RWD: using incorrect surrogate markers for missing data and/or classification errors, ignoring deaths at time zero, and failing to account for guarantee-time bias. METHODS: The ASCO CLQD MM data set (July 19, 2021, release) was used to compare overall survival (OS) in patients with a known versus presumed date of MM diagnosis, in patients with secondary AML (sAML) with early deaths (ie, 0 months) included versus dropped, and in patients with second primary malignancies (SPMs) matched versus unmatched to control for time-related confounding factors (ie, guarantee-time bias). Analyses were conducted using STATA Version 17.0 (College Station, TX). RESULTS: In the CLQD MM data set, 28% of patients were missing a diagnosis date. Attempts to use the presumed diagnosis date (ie, first bortezomib or lenalidomide administration) as a surrogate marker for missing diagnosis dates were not successful as median OS was significantly different in patients with a recorded versus presumed diagnosis date (107 v 40 months, hazard ratio [HR], 2.5; 95% CI, 2.39 to 2.64; P < .001). Dropping deaths within 1 month of sAML diagnosis resulted in an exaggerated median OS (46 v 39 months). OS in patients with MM with SPMs differed substantially before and after incorporation of matching methods to account for guarantee-time bias (HR, 0.73; 95% CI, 0.67 to 0.78; P < .001 before matching, HR, 1.30; 95% CI, 1.18 to 1.43; P < .001 after matching). CONCLUSION: To fully maximize the benefits of RWD in oncology research, clinicians must be aware of analytic methods that can overcome pitfalls in survival analyses.

Incidence and prevalence of eating disorders among active duty US military-dependent youth from 2016 to 2021.

OBJECTIVE: The offspring of US military service members may be at increased risk for eating disorders. However, no epidemiological studies to date have evaluated eating disorder incidence rates and prevalence estimates among military-dependent youth. METHOD: This retrospective cohort study examined eating disorder diagnoses in the military healthcare system (MHS) from 2016 through 2021. Active duty and national guard military-dependent youth, aged 10-17 years, who received care in the MHS via TRICARE Prime insurance, were identified by one or more ICD-10 codes indicative of an eating disorder diagnosis (anorexia nervosa, bulimia nervosa, binge-eating disorder, and other-specified eating disorders). RESULTS: During the 6-year surveillance period, 2534 dependents received incident diagnoses of eating disorders, with a crude overall incidence rate of 1.75 cases per 10,000 person-years. The most common diagnosis was other-specified eating disorder, followed by anorexia nervosa, bulimia nervosa, and binge-eating disorder. The crude annual incidence rate of all eating disorder diagnoses increased by nearly 65% from 2016 to 2021. Rates for all diagnoses were highest in 2020 and 2021. Period prevalence estimates were .08% for any eating disorder diagnosis, .01% for anorexia nervosa, .004% for bulimia nervosa, .004% for binge-eating disorder, and .06% for other-specified eating disorders. DISCUSSION: The observed increase in eating disorder diagnoses during the surveillance period appeared to be driven by female dependents. More military dependents experienced a new-onset diagnosis during the COVID-19 pandemic compared to previous years. These findings highlight the need for eating disorder screening, identification, and treatment for dependents within the MHS. PUBLIC SIGNIFICANCE STATEMENT: Children of US military service members may be at increased risk for eating disorders. Results indicate new-onset eating disorder cases increased 65% from 2016 to 2021, primarily among girls compared to boys. The most diagnosed and fastest growing diagnosis was other-specified eating disorder. Rates of anorexia nervosa increased following the COVID-19 pandemic. Findings highlight the need for eating disorder screening, identification, and treatment within the military healthcare system.

Survival of U.S. Military Service Members With Lymphoma.

INTRODUCTION: Cancer is a prominent cause of mortality in today's active duty service members (ADSMs), killing over 700 ADSMs between 2004 and 2015. Hence, more research is needed to better understand the survival of U.S. service members with cancer. Lymphoma is the most common hematologic malignancy diagnosed in ADSMs, serving as a good cancer type to study. MATERIALS AND METHODS: The Department of Defense tumor registry and the Surveillance, Epidemiology, and End Result (SEER) databases were retrospectively accessed to analyze overall survival (OS) of ADSMs with lymphoma and to compare outcomes with matched civilians. ADSMs with Hodgkin lymphoma (HL), diffuse large B-cell lymphoma (DLBCL), and indolent lymphoma diagnosed between 1997 and 2017 were included, and SEER comparator patients were matched by age, sex, race, stage, and year of diagnosis using a 4:1 ratio of civilians to ADSMs. RESULTS: There were 1,170, 443, and 284 ADSMs with HL, DLBCL, and indolent lymphoma, respectively, and all three groups had superior OS when compared to their matched civilian counterparts with 35%, 49%, and 48% reductions in the risk of death, respectively. There were no differences in ADSM survival based on race, sex, or rank, despite disparities being pervasive in the civilian sector. CONCLUSIONS: Service members with lymphoma have superior survival than their matched civilian counterparts, without evident racial or sex disparities. Results of this study are favorable in terms of readiness. Further research on cancer mortality in ADSMs is needed to improve long-term outcomes.

The effects of hyperbaric oxygen on MRI findings in rheumatoid arthritis: A pilot study.

Background: Rheumatoid arthritis is a debilitating and destructive disease for which limited therapeutic options exist. Objective: This report summarizes serial magnetic resonance imaging (MRI) findings from nine study participants treated with hyperbaric oxygen (HBO2) therapy and expands upon an earlier pilot study that showed improvement in disease activity and joint pain as determined by multiple, validated clinical measures. Methods: Rheumatoid arthritis patients received 30 hyperbaric oxygen treatments over six to 10 weeks. MRI with and without contrast was completed at baseline, and at three- and six-month intervals following initiation of HBO2 therapy. Ratings were based on Outcome Measures in Rheumatology Clinical Trials (OMERACT) Rheumatoid Arthritis Magnetic Resonance Imaging Score (RAMRIS) criteria, the standard method for quantification of inflammation and damage by MRI in RA trials. Results: Using RAMRIS criteria, nine of nine patients demonstrated no radiologic progression of erosions, synovitis, or bone marrow edema at three- and six-month scans. Conclusion: Our findings suggest that HBO2 therapy may be useful as an adjunctive or alternative treatment to disease-modifying drugs for rheumatoid arthritis.

Structured Curricular Change Fails to Combat Resident Burnout.

INTRODUCTION: During the 2020-2021 academic year, the Family Medicine (FM) faculty at David Grant USAF Medical Center (DGMC) incorporated Clinic First principles into the resident educational experience. The faculty hypothesized that these changes could improve symptoms of resident burnout. MATERIALS AND METHODS: The study was conducted at a single United States Air Force (USAF) FM residency program in California and was approved by the DGMC Institutional Review Board. The validated Maslach Burnout Inventory Human Services Survey for Medical Personnel was used to assess (1) emotional exhaustion, (2) depersonalization, and (3) personal achievement both prior to and following implementation of the Clinic First-inspired curriculum. Descriptive and inferential statistics were used to summarize the data. RESULTS: There were 25 eligible FM residents who participated in the study. At baseline, the mean scores on the Maslach Burnout Inventory Human Services Survey for Medical Personnel indicated moderate burnout across all 3 domains. There was a statistically significant difference (P = .03) in the mean EE score over time, demonstrating worsening exhaustion. There was no statistically significant difference (P = .37 and P = .08, respectively) in the mean DP or PA score over time. CONCLUSIONS: Residents in the DGMC FM residency program were experiencing moderate burnout at the beginning of the 2020-2021 AY. Due to unforeseen challenges, the Clinic First initiative was not realized in its full potential, and the curriculum changes did not definitively protect against burnout. Further study is indicated.

Effectiveness of Lifestyle Interventions in an Active Duty Air Force Population.

PURPOSE: To examine the effectiveness of 3 lifestyle intervention programs in an active duty military population. DESIGN: Experimental design with stratified random assignment to 1 of 3 intervention groups. Measures were taken at baseline, 3 months and 6 months. SETTING: A Military Treatment Facility in the western U.S. SUBJECTS/INTERVENTION: 122 active duty service members were enrolled and randomly assigned to 1 of 3 lifestyle intervention programs: the Diabetes Prevention Program-Group Lifestyle Balance (DPP-GLB), the Better Body Better Life (BBBL) program or the Fitness Improvement Program (FIP). MEASURES: weight, abdominal circumference, lipid and HbA1c levels, physical activity, and well-being as measured by the RAND SF-36 questionnaire. ANALYSIS: Statistical analyses were performed to assess changes over time. RESULTS: 83 participants completed the study (BBBL N = 23, FIP N = 30, DPP-GLB N = 30). The DPP-GLB participants had statistically significant decreases in weight (-3.1 pounds, p = .01) and abdominal circumference (-0.9 inches; p = .01) over time. HbA1c was also significantly lower in this group at 6 months compared to baseline (p = .036). There were no statistically significant changes in weight, abdominal circumference, or HbA1c in the FIP or BBBL groups. No significant changes were observed in lipids in any of the groups. CONCLUSION: Results from this study indicate that the DPP-GLB program may be effective in reducing weight, abdominal circumference, and HbA1c in an active duty U.S. military population.

A Survey of Energy Drink Consumption and Associated Adverse Effects in Air Force Personnel.

INTRODUCTION: Energy drinks are an increasingly utilized beverage and are gaining popularity in recent years. The U.S. Air Force (USAF) represents a unique population where energy drink consumption may be higher than the general population. To better understand the safety and health impact of energy drinks, this large-scale comprehensive survey was conducted to study energy drink consumption patterns and its associated adverse effects. MATERIALS AND METHODS: A survey was conducted across 12 USAF installations to assess self-reported energy drink consumption and adverse effects in the military population. This study was approved by the David Grant USAF Medical Center Institutional Review Board. RESULTS: A total of 9,655 participants participated in the survey. Energy drink consumption was reported in 76.7% of the participants, with 12.0% consuming ≥1 energy drink per day. Male gender, younger age, and enlisted military members are more likely to be high consumers; 58.6% of participants reported having at least once tried a premixed beverage that combines alcohol, caffeine, and other stimulants. Among energy drink users, 60.0% reported experiencing ≥1 adverse effect, and 0.92% reported needing to see a physician or going to the emergency department because of adverse effects from energy drinks. Higher energy drink or premixed combination beverage consumption frequency was associated with increased likelihood of physician or emergency department visits (P ≤ 0.002 for both). CONCLUSION: Approximately three in four USAF members reported ever consuming an energy drink. Caution should be exercised on the amount of energy drink consumed to limit the risk of serious adverse effects. Future studies should identify populations at greatest risk for adverse effects and alternative sources of energy maintenance to attain optimal mission readiness.

The Effects of Hyperbaric Oxygen on Rheumatoid Arthritis: A Pilot Study.

BACKGROUND/OBJECTIVE: This case series pilot study assessed the effects of hyperbaric oxygen therapy (HBO2) for treating rheumatoid arthritis (RA). METHODS: Ten RA subjects received 30 HBO2 treatments over 6 to 10 weeks. Serial rheumatologic evaluations (ie, the Disease Activity Scale [DAS28], the Routine Assessment of Patient Index Data 3, and the Pain and Sleep Quality Questionnaire) were completed at baseline, throughout the course of the study, and at the 6-month follow-up. RESULTS: There was a statistically significant effect of HBO2 therapy over time on the DAS28-Global Health (p = 0.01), the DAS28-C-reactive protein (p = 0.002), and the DAS28-erythrocyte sedimentation rate (p = 0.008) measures; these analyses excluded 2 patients who were in clinical remission at baseline. Selected post hoc comparisons showed significantly lower DAS28-Global Health, DAS28-C-reactive protein, and DAS28-erythrocyte sedimentation rate scores at 3 and 6 months relative to baseline. In addition, statistically significant decreases in pain as measured by the Routine Assessment of Patient Index Data 3 and Pain and Sleep Quality Questionnaire were observed at the end of HBO2 relative to baseline. CONCLUSIONS: Hyperbaric oxygen therapy is effective for joint pain in patients with RA based on data from multiple, validated clinical measures. Further research with more subjects and the use of a control group is necessary.

Evidence of vaccinia dissemination despite lack of major reaction following smallpox vaccination.

Following vaccinia vaccination, vesicle formation at the site occurs in 95% of primary vaccinees and is thought to indicate virus replication and vaccine efficacy. Little is known about virus replication and immune response in those who do not develop a vesicle. We used PCR to detect vaccinia in various sites following receipt of the smallpox vaccine in those with and without vesicle formation. Among 80 participants, 74 developed and 6 failed to develop a vesicle. Vaccinia DNA was detected in the blood, in the oropharynx, on the dressing, and on the hands of 5%, 11%, 4%, and 0% of those with vesicle formation and of 33%, 17%, 0%, and 17% of those without vesicle formation, respectively (p > 0.05 for each site). The detection of systemic vaccinia DNA in vaccinees without vesicle formation challenges the current understanding that lack of vesicle formation indicates lack of virus replication, the prerequisite to immune response.

What determines supportive behaviors following bereavement? A systematic review and call to action.

Very few factors that impact the grieving process can be modified after the fact to the extent that social support can. However, social support has received limited research attention, resulting in little conceptual understanding of the mechanisms behind perceptions of, and intentions to support, grieving persons. This systematic review aimed to explore bereaved, decedent, and respondent-related determinants of the provision of social support. The review yielded 42 studies impacted by various methodological and sampling limitations. This review poses a call to the field for more rigorous study of social support determinants to better assist the bereaved and their natural supporters.

Social support following bereavement: The role of beliefs, expectations, and support intentions.

Social support is one of the strongest determinants of bereavement outcomes, yet little is understood about the community's recognition of grief and intentions to provide social support to grieving persons. A total of 476 adults responded to an online vignette and questionnaire measuring grief norms and supportive intentions. Respondent gender, age, and bereavement status all had some association with expectations of grief, intentions to support, perceived helpfulness of support attempts, and opinions toward the diagnostic classification of grief. Given that most bereavement support is informal, this study informs the development of community capacity to provide constructive, timely bereavement support.

The role of deliberate practice in the development of highly effective psychotherapists.

Little empirical research exists about highly effective psychotherapists, and none about the factors that mediate the acquisition and maintenance of superior performance skills (e.g., Ericsson, 1996, 2006; Ericsson, Krampe, & Tesch-Romer, 1993). In the full sample, a 3-level multilevel modeling (Level 1: clients; Level 2: therapists; Level 3: organization types) of practitioner outcomes was used to examine the contribution of the therapist to treatment effectiveness. Consistent with prior research, in the full sample (n = 69 therapists; n = 4,580 clients) it was found that therapist effects explained 5.1% of the variance in outcome, after adjusting for initial severity. Therapist gender, caseload, and age were not found to be significant predictors. In a subsample of therapists, the relationship between outcome and therapist demographic variables, professional development activities, and work practices was analyzed (n = 17 therapists, n = 1,632 clients). Therapist characteristics (e.g., years of experience, gender, age, profession, highest qualification, caseload, degree of theoretical integration) did not significantly predict client-reported outcomes. Consistent with the literature on expertise and expert performance, the amount of time spent targeted at improving therapeutic skills was a significant predictor of client outcomes. Further, highly effective therapists indicated requiring more effort in reviewing therapy recordings alone than did the rest of the cohort. Caveats and implications for clinical practice, continuing professional development, and training are discussed.

Effects of 2 adenosine antagonists, quercetin and caffeine, on vigilance and mood.

Quercetin, a phenolic flavonoid found in small quantities in some fruits and vegetables, is an adenosine receptor antagonist in vitro marketed as a dietary supplement for purported caffeine-like effects. A double-blind, placebo-controlled, between-subjects study was conducted to compare the behavioral effects of quercetin to a central adenosine receptor antagonist, caffeine. Fifty-seven volunteers received either 2000 mg of quercetin dihydrate (a dose estimated based on in vitro receptor binding to be equivalent in potency to 200 mg of caffeine), placebo, or 200 mg of caffeine. One hour later, a 45-minute visual vigilance task was administered. The Profile of Mood States questionnaire was completed before treatment and immediately after vigilance testing. On the vigilance task, caffeine increased the number of stimuli detected (P < 0.02) and decreased the reaction time (P = 0.001). Caffeine increased self-reported vigor and reduced fatigue and total mood disturbance Profile of Mood States scores compared with placebo. Quercetin did not significantly alter any parameter, but values were typically intermediate between caffeine and placebo on those tests affected by caffeine. Quercetin is unlikely to have any effects when consumed by humans in quantities present in the diet or in dietary supplements. Caffeine (200 mg) administration resulted in the expected effects on vigilance and mood.

Comparison of a semipermeable dressing bonded to an absorbent pad and a semipermeable dressing over a separate gauze pad for containment of vaccinia virus at the vaccination site.

OBJECTIVE: To compare the ability of 2 types of dressings to contain vaccinia virus after smallpox vaccination. DESIGN: Prospective, nonrandomized trial. SETTING: The smallpox vaccination clinic in a medium-sized military hospital. PARTICIPANTS: Ninety-seven active-duty military members who received smallpox vaccination in accordance with US Department of Defense and Centers for Disease Control and Prevention guidelines. METHODS: The first 40 participants enrolled were instructed to cover their vaccination sites with a semipermeable membrane placed over a separate gauze pad, and the subsequent 57 participants were given a semipermeable membrane bonded to an absorbent pad. Swab samples of the external surface of the dressing were collected 7 and 21 days after vaccination. Real-time quantitative polymerase chain reaction was used to detect vaccinia DNA in the samples. RESULTS: The rate of vaccinia DNA detection was significantly higher for samples obtained from vaccinees who were using the separate gauze and semipermeable membrane, compared with the vacinees who were using the gauze-impregnated semipermeable membrane (22% vs 2.2%; ; odds ratio, 12.3 [95% confidence interval, 1.4-567.4]). CONCLUSION: A gauze-impregnated semipermeable membrane more effectively reduced viral passage to the external surface of the dressing than did a semipermeable membrane placed over a separate gauze pad. Routine use of such dressings following smallpox vaccination might reduce the incidence of autoinoculation and secondary transmission.

Rapid determination of macrolide and lincosamide resistance in group B streptococcus isolated from vaginal-rectal swabs.

OBJECTIVE: Our objective was to assess the ability of real-time PCR to predict in vitro resistance in isolates of group B streptococcus (GBS). METHODS: The first real-time PCR assays for the genes known to confer resistance to erythromycin and clindamycin in GBS were developed. Three hundred and forty clinical GBS isolates were assessed with these assays and compared with conventional disk diffusion. RESULTS: The presence of an erythromycin ribosome methylation gene (ermB or ermTR variant A) predicted in vitro constitutive or inducible resistance to clindamycin with a sensitivity of 93% (95% CI 86%-97%), specificity of 90% (95% CI 85%-93%), positive predictive value of 76% (95% CI 67%-84%), and negative predictive value of 97% (95% CI 94%-99%). CONCLUSION: This rapid and simple assay can predict in vitro susceptibility to clindamycin within two hours of isolation as opposed to 18-24 hours via disk diffusion. The assay might also be used to screen large numbers of batched isolates to establish the prevalence of resistance in a given area.

Urogynecology practice patterns among Air Force obstetricians and gynecologists: survey results.

The objective of this study was to describe the practice patterns of physicians in the United States Air Force regarding the evaluation and treatment of female pelvic floor disorders including urinary incontinence and pelvic organ prolapse. A self-administered survey of 22 questions was electronically mailed to all active duty Air Force obstetricians & gynecologists. Fifty-one surveys were returned for a 51% response rate. Eighty-four percent of physicians treat urinary incontinence. A smaller percentage perform advanced reconstructive techniques, using biomaterials (35%), colpocleisis (39%), overlapping sphincter repairs (45%), and abdominal sacrocolpopexy (27%). When questioned about urogynecology training during residency, most respondents report inadequate training in advanced pelvic surgery techniques. In conclusion, the majority of Air Force obstetricians and gynecologists feel comfortable treating uncomplicated urinary incontinence but do not routinely perform advanced urogynecology surgeries. There is a continued need to train physicians in female pelvic medicine to treat a unique patient population.

Does gel affect cytology or comfort in the screening papanicolaou smear?

PURPOSE: Current medical training recommends obtaining cervical cytological specimens without the use of lubricating gel. The purpose of this study was to determine whether water-soluble lubricant gel affects cytologic outcomes in the screening Papanicolaou smear and patient comfort during vaginal speculum examination. METHODS: The study was a randomized controlled trial performed at David Grant US Air Force Medical Center (Travis Air Force Base, CA). Participants were female patients at least 18 years old presenting for an annual Papanicolaou smear. Each patient, blinded to group assignment, consented to two consecutive Papanicolaou smears. The first Papanicolaou smear was performed without gel in all subjects as part of the "standard of care." Thirty control patients underwent a second examination with no gel, and 40 other patients had the second examination with gel. All patients rated the discomfort of each Papanicolaou smear on a numerical pain scale. Main outcome measures were cytologic discrepancies on standard glass slide samples and comfort differences regarding the use of gel lubrication. Fisher's exact test was used to interpret the effect of gel on cytology results. Student's t test was performed to compare the discomfort ratings for the second Papanicolaou smear in the GEL vs. the NO GEL groups. RESULTS: There was no statistically significant difference between the number of inadequate Papanicolaou smears (P = .50) nor in the discomfort level ratings in the GEL vs. the NO GEL groups (P = .69). CONCLUSION: Speculum gel lubrication does not affect cervical cytology during the traditional Papanicolaou smear, nor does it provide significant alteration of patient discomfort.
