ABSTRACT

The concept of resilience is embedded within military culture and professional identity. To date, temporal changes in individuals' perceptions of their own resilience have not been systematically assessed in highstakes occupational contexts, like the military. The current study examined change in selfreported resilience over time by: (1) examining the longitudinal measurement invariance of the Brief Resilience Scale (BRS); (2) assessing the longitudinal pattern of resilience across a combat deployment cycle; and (3) examining predictors of postdeployment resilience and change in resilience scores across time. U.S. Army soldiers assigned to a combat brigade completed a survey at four time points over the course of a deployment cycle: (a) prior to deployment to Afghanistan; (b) during deployment; (c) immediately following return to home station; and (d) approximately 2-3 months thereafter. The longitudinal measurement invariance of the BRS was established. Growth curve modeling indicated that, on average, self-reported resilience decreased across the deployment cycle, but there was considerable individual variation in the rate of change. Of note, loneliness, as measured during deployment, predicted the rate of change in self-reported resilience over time. Results have implications for the longitudinal analysis of resilience and for the development of interventions with military personnel.

ABSTRACT

Motile and non-motile cilia play critical roles in mammalian development and health. These organelles are composed of a 1000 or more unique proteins, but their assembly depends entirely on proteins synthesized in the cell body and transported into the cilium by intraflagellar transport (IFT). In mammals, malfunction of non-motile cilia due to IFT dysfunction results in complex developmental phenotypes that affect most organs. In contrast, disruption of motile cilia function causes subfertility, disruption of the left-right body axis, and recurrent airway infections with progressive lung damage. In this work, we characterize allele specific phenotypes resulting from IFT74 dysfunction in human and mice. We identified two families carrying a deletion encompassing IFT74 exon 2, the first coding exon, resulting in a protein lacking the first 40 amino acids and two individuals carrying biallelic splice site mutations. Homozygous exon 2 deletion cases presented a ciliary chondrodysplasia with narrow thorax and progressive growth retardation along with a mucociliary clearance disorder phenotype with severely shorted cilia. Splice site variants resulted in a lethal skeletal chondrodysplasia phenotype. In mice, removal of the first 40 amino acids likewise results in a motile cilia phenotype but with little effect on primary cilia structure. Mice carrying this allele are born alive but are growth restricted and developed hydrocephaly in the first month of life. In contrast, a strong, likely null, allele of Ift74 in mouse completely blocks ciliary assembly and causes severe heart defects and midgestational lethality. In vitro studies suggest that the first 40 amino acids of IFT74 are dispensable for binding of other IFT subunits but are important for tubulin binding. Higher demands on tubulin transport in motile cilia compared to primary cilia resulting from increased mechanical stress and repair needs could account for the motile cilia phenotype observed in human and mice.

ABSTRACT

Motile and non-motile cilia are critical to mammalian development and health. Assembly of these organelles depends on proteins synthesized in the cell body and transported into the cilium by intraflagellar transport (IFT). A series of human and mouse IFT74 variants were studied to understand the function of this IFT subunit. Humans missing exon 2, which codes for the first 40 residues, presented an unusual combination of ciliary chondrodysplasia and mucociliary clearance disorders while individuals carrying biallelic splice site variants developed a lethal skeletal chondrodysplasia. In mice, variants thought to remove all Ift74 function, completely block ciliary assembly and result in midgestational lethality. A mouse allele that removes the first 40 amino acids, analogous to the human exon 2 deletion, results in a motile cilia phenotype with mild skeletal abnormalities. In vitro studies suggest that the first 40 amino acids of IFT74 are dispensable for binding of other IFT subunits but are important for tubulin binding. Higher demands on tubulin transport in motile cilia compared to primary cilia could account for the motile cilia phenotype observed in human and mice.

ABSTRACT

INTRODUCTION: At the start of the coronavirus disease 2019 (COVID-19) pandemic, Walter Reed Army Institute of Research (WRAIR) mobilized to rapidly conduct medical research to detect, prevent, and treat the disease in order to minimize the impact of the pandemic on the health and readiness of U.S. Forces. WRAIR's major efforts included the development of the Department of Defense (DoD) COVID-19 vaccine candidate, researching novel drug therapies and monoclonal antibodies, refining and scaling-up diagnostic capabilities, evaluating the impact of viral diversity, assessing the behavioral health of Soldiers, supporting U.S. DoD operational forces overseas, and providing myriad assistance to allied nations. WRAIR personnel have also filled key roles within the whole of government response to the pandemic. WRAIR had to overcome major pandemic-related operational challenges in order to quickly execute a multimillion-dollar portfolio of COVID-19 research. Consequently, the organization learned lessons that could benefit other leaders of medical research organizations preparing for the next pandemic. MATERIALS AND METHODS: We identified lessons learned using a qualitative thematic analysis of 76 observation/recommendation pairs from across the organization. These lessons learned were organized under the Army's four pillars of readiness (staffing, training, equipping, and leadership development). To this framework, we added organizing and leading to best capture our experiences within the context of pandemic response. RESULTS: The major lessons learned for organizing were: (1) the pandemic created a need to rapidly pivot to new scientific priorities; (2) necessary health and safety precautions disrupted the flow of normal science and put programs at risk of missing milestones; (3) relationships with partners and allies facilitated medical diplomacy and advancement of U.S. national military and economic goals; and (4) a successful response required interoperability within and across multiple organizations. For equipping: (1) existing infrastructure lacked sufficient capacity and technical capability to allow immediate countermeasure development; (2) critical supply chains were strained; and (3) critical information system function and capacity were suddenly insufficient under maximum remote work. For staffing and training: (1) successful telework required rapid shifts in management, engagement, and accountability methods; and (2) organizational policies and processes had to adapt quickly to support remote staffing. For leading and leadership development (1) engaged, hopeful, and empathetic leadership made a difference; and (2) the workforce benefitted from concerted leadership communication that created a shared understanding of shifting priorities as well as new processes and procedures. CONCLUSIONS: An effective pandemic response requires comprehensive institutional preparedness that facilitates flexibility and surge capacity. The single most important action leaders of medical research organizations can take to prepare for the next pandemic is to develop a quick-reaction force that would activate under prespecified criteria to manage reprioritization of all science and support activities to address pandemic response priorities at the velocity of relevance.

ABSTRACT

Introduction: COVID-19 hospitalizations and deaths have raised the need of identifying prognostic factors for medical decision-making. Methods: Observational, retrospective study analyzing 191 COVID-19 patients' serum inflammatory biomarkers. Results: The median age was 48.7 ± 12.7 years, 75.9% being men. Overweight/obesity was the most common comorbidity in 83.8% of patients. 44.5% had moderate disease followed by 43.5% with severe disease. The mean percentage of pulmonary damage was 53.4% ± 28.7. Serum leukocyte-to-lymphocyte ratio >7.7, neutrophil-to-lymphocyte ratio >10, platelet-to-lymphocyte ratio ≥250 and nutritional index <362 all were independent mortality predictors for COVID-19. Conclusions: A leukocyte-to-lymphocyte ratio >7.7 as well as a nutritional index <362 at hospitalization were independently associated with an increased mortality.

ABSTRACT

BACKGROUND: For decades confirmatory factor analysis (CFA) has been the preeminent method to study the underlying structure of posttraumatic stress disorder (PTSD); however, methodological limitations of CFA have led to the emergence of other analytic approaches. In particular, network analysis has become a gold standard to investigate the structure and relationships between PTSD symptoms. A key methodological limitation, however, which has significant clinical implications, is the lack of data on the potential impact of item order effects on the conclusions reached through network analyses. METHODS: The current study, involving a large sample (N = 5055) of active duty army soldiers following deployment to Iraq, assessed the vulnerability of network analyses and prevalence rate to item order effects. This was done by comparing symptom networks of the DSM-IV PTSD checklist items to these same items distributed in random order. Half of the participants rated their symptoms on traditionally ordered items and half the participants rated the same items, but in random order and interspersed between items from other validated scales. Differences in prevalence rate and network composition were examined. RESULTS: The prevalence rate differed between the ordered and random item samples. Network analyses using the ordered survey closely replicated the conclusions reached in the existing network analyses literature. However, in the random item survey, network composition differed considerably. CONCLUSION: Order effects appear to have a significant impact on conclusions reached from PTSD network analysis. Prevalence rates were also impacted by order effects. These findings have important diagnostic and clinical treatment implications.

ABSTRACT

Across the globe, the consumption of energy-dense and nutrient-poor foods and beverages has escalated rates of diet-related non-communicable diseases (NCDs), driven by deceptive marketing tactics from the food and beverage industry. The international community has increasingly recognized the need to provide consumers with accurate health information on food and beverage products as part of their right to health. In July 2020, the U.N. Special Rapporteur on the right to health released a powerful Statement calling for the adoption of front-of-package warning labeling to tackle NCDs. Just a few weeks after the Statement's release, the Pan American Health Organization published a report highlighting the relevance of front-of-package labeling as a policy tool for the prevention of NCDs in the Americas, demonstrating further support to this regulatory intervention.In this piece, we explain why front-of-package warning labeling should be part of a comprehensive strategy to promote healthier lives, delving into the human-rights aspects of front-of-package labels. In particular, we explore the role the food and beverage industry play in increasing the consumption of unhealthy foods and beverages, and the relevance of scientific evidence free from conflicts of interest to adequately protect the right to health and health-related rights.

ABSTRACT

The Hedgehog pathway, critical to vertebrate development, is organized in primary cilia. Activation of signaling causes the Hedgehog receptor Ptch1 to exit cilia, allowing a second receptor, Smo, to accumulate in cilia and activate the downstream steps of the pathway. Mechanisms regulating the dynamics of these receptors are unknown, but the ubiquitination of Smo regulates its interaction with the intraflagellar transport system to control ciliary levels. A focused screen of ubiquitin-related genes identified nine required for maintaining low ciliary Smo at the basal state. These included cytoplasmic E3s (Arih2, Mgrn1, and Maea), a ciliary localized E3 (Wwp1), a ciliary localized E2 (Ube2l3), a deubiquitinase (Bap1), and three adaptors (Kctd5, Skp1a, and Skp2). The ciliary E3, Wwp1, binds Ptch1 and localizes to cilia at the basal state. Activation of signaling removes both Ptch1 and Wwp1 from cilia, thus providing an elegant mechanism for Ptch1 to regulate ciliary Smo levels.

ABSTRACT

BACKGROUND: Prior research has identified behavioural health outcomes as key sequelae to combat deployment. However, relatively little is known about differential patterns of change in depression or generalised anxiety linked to deployment to a combat zone. In this paper, we add to the existing trajectory literature and examine key predictive factors of behavioural health risk. AIMS: The primary aim is to leverage growth mixture modelling to ascertain trajectories of psychological distress, operationalised as a coherent construct combining depression and generalised anxiety, and to identify factors that differentiate adaptive and maladaptive patterns of change. METHOD: Data were collected from a brigade combat team prior to a combat deployment to Afghanistan, during deployment, at immediate re-integration and approximately 2-3 months thereafter. The main outcome was measured using the Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS). RESULTS: Three latent trajectories were identified: a low-stable trajectory, a declining trajectory and a rising trajectory. Most individuals aligned with the low-stable trajectory. A conditional model using covariates measured during deployment showed that the low-stable trajectory differed consistently from the remaining trajectories on self-reported loneliness and non-combat deployment stressors. CONCLUSIONS: The examination of differential patterns of adaptation, to identify individuals at higher risk, is critical for the efficient targeting of resources. Our findings further indicate that loneliness may be a useful leverage point for clinical and organisational intervention.

ABSTRACT

OBJECTIVE: To evaluate the longitudinal relationships between unit cohesion, Army leader behaviors, and subordinate suicidal/death ideation. Recent cross-sectional research indicates that subordinates who perceive that their leaders instill a sense of purpose regarding military service demonstrate less frequent suicidal ideation. METHOD: Five hundred fifty-nine soldiers completed self-report measures of perceptions of leadership behaviors, unit cohesion, and suicidal/death ideation during deployment as well as one and three months following deployment. Latent change score modeling was conducted to evaluate the course and direction of study variables as well as the relationship between them. RESULTS: Although lower levels of suicidal/death ideation were related to leader-provided purpose, leader-provided meaning, and unit cohesion at baseline, only leader-provided purpose and unit cohesion prospectively predicted changes in suicidal/death ideation. CONCLUSIONS: Consistent with the goal of military leadership to augment effective clinical interventions that reduce suicide risk, prevention programs that reach a broader population of personnel should be considered. Enhanced leadership training may be an important primary prevention tool to reduce suicide risk that warrants further research.

ABSTRACT

The programmable sequence specificity of CRISPR has found uses in gene editing and diagnostics. This manuscript describes an additional application of CRISPR through a family of novel DNA enrichment technologies. CAMP (CRISPR Associated Multiplexed PCR) and cCAMP (chimeric CRISPR Associated Multiplexed PCR) utilize the sequence specificity of the Cas9/sgRNA complex to target loci for the ligation of a universal adapter that is used for subsequent amplification. cTRACE (chimeric Targeting Rare Alleles with CRISPR-based Enrichment) also applies this method to use Cas9/sgRNA to target loci for the addition of universal adapters, however it has an additional selection for specific mutations through the use of an allele-specific primer. These three methods can produce multiplex PCR that significantly reduces the optimization required for every target. The methods are also not specific to any downstream analytical platform. We additionally will present a mutation specific enrichment technology that is non-amplification based and leaves the DNA in its native state: TRACE (Targeting Rare Alleles with CRISPR-based Enrichment). TRACE utilizes the Cas9/sgRNA complex to sterically protect the ends of targeted sequences from exonuclease activity which digests both the normal variant as well as any off-target sequences.

ABSTRACT

Adverse childhood experiences (ACEs) can have long-term impacts on a person's mental health, which extend into adulthood. There is a high prevalence of ACEs among service members. Further, service members also report frequently experiencing disrupted sleep. We hypothesized that disrupted sleep may serve a mechanistic function connecting ACEs to functional impairment and poorer mental health. In a cross-sectional sample (n = 759), we found evidence for an indirect effect of ACEs on mental health outcomes through disrupted sleep. In a different sample using two time-points (n = 410), we found evidence for an indirect effect of ACEs on changes in mental health outcomes and functional impairment during a reset period, through changes in disrupted sleep during the same period. Implications, limitations and future research directions are discussed.

ABSTRACT

INTRODUCTION: The goal of the present study was to characterize behavioral health rates, behavioral health care utilization, loneliness, and perceived prejudice and support among sexual minority soldiers. MATERIALS AND METHODS: Cross-sectional survey data were obtained from 640 active-duty U.S. soldiers enrolled in an academic training institute who provided information on their sexual orientation. Survey topics included demographics, behavioral health, behavioral health care utilization, and mitigating factors (eg, perceived prejudice, perceived support, and loneliness). Chi-square analyses were utilized to determine any differences between groups for behavioral health rates and behavioral health care utilization. Robust regression was used for analysis of self-reported loneliness. RESULTS: A higher proportion of lesbian, gay, bisexual (LGB) soldiers than heterosexual soldiers screened positive for anxiety, post-traumatic stress disorder, and suicidality. No between-group differences in behavioral health care utilization were found; however, a higher proportion of LGB soldiers sought help from military family life counselors. No between-group differences for loneliness were found. Finally, perceived prejudice was higher for LGB soldiers and perceived support was lower. CONCLUSION: Organizational barriers, such as perceived prejudice and lack of support, appear to still exist for sexual minority soldiers. Increasing organizational support and implementing training and education for health care providers in order to better support the LGB soldier community may mitigate these barriers.

ABSTRACT

An estimated 20-30% of adult women who experience an initial urinary tract infection (UTI) will have recurrent infection. In these patients, prophylaxis may be considered to improve their quality of life and control overuse of antibiotics. Despite this need, there is currently no Latin American consensus on the treatment and prophylaxis of recurrent UTIs. This consensus, signed by a panel of regional and international experts on UTI management, aims to address this need and is the first step toward a Latin American consensus on a number of urogynecological conditions. The panel agrees that antibiotics should be considered the primary treatment option for symptomatic UTI, taking into account local pathogen resistance patterns. Regarding prophylaxis, immunoactive therapy with the bacterial lysate OM-89 received a grade A recommendation and local estrogen in postmenopausal women grade B recommendation. Lower-grade recommendations include behavior modification and D-mannose; probiotics (Lactobacilli), cranberries, and hyaluronic acid (and derivatives) received limited recommendations; their use should be discussed with the patient. Though considered effective and receiving grade A recommendation, antimicrobial prophylaxis should be considered only following prophylaxis with effective non-antimicrobial measures that were not successful and chosen based on the frequency of sexual intercourse and local pathogen resistance patterns.

ABSTRACT

Suicide in U.S. Army Soldiers is of major concern as it is estimated that over 100 Soldiers die by suicide each year. Examining risk and protective factors is essential to develop both an understanding of Soldier suicide as well as inform systemic interventions to reduce suicide. One potential systemic approach is to embed preventive mechanisms within the structure of the military rather than the typical administration of primary intervention through mandatory training. To examine potential mechanisms of leader-based interventions, several leadership behaviors were assessed in a cross-sectional sample of n = 1,096 active duty Soldiers. Soldiers completed self-report measures of interpersonal predictors of suicide, suicidal ideation (SI), leadership behaviors, and unit cohesion. Logistic regression was used to identify leadership behaviors related to SI. Only the leader behavior attempting to foster a sense of purpose predicted SI. Leader provided purpose (LPP) was then entered into indirect effect analyses to evaluate the mechanisms of this relationship. Analyses revealed that LPP predicted SI through unit cohesion, thwarted belongingness, and perceived burdensomeness. Results demonstrate that specific aspects of military leadership such as fostering Soldier purpose may enhance resilience and reduce risk for SI.
