Insufficient Sleep and Behavioral Health in the Military: A 5-Country Perspective.

PURPOSE OF REVIEW: The goal of this paper was to highlight the degree to which sleep, behavioral health, and leader involvement were interrelated using data from militaries in five English-speaking countries: Australia, Canada, New Zealand, the UK, and the United States. RECENT FINDINGS: Many service members reported sleeping fewer than the recommended 7 h/night: 34.9%, 67.2%, and 77.2% of respondents from New Zealand, Canada, and the United States, respectively. Countries reporting shorter sleep duration also reported fewer insomnia-related difficulties, likely reflecting higher sleep pressure from chronic sleep loss. Across all countries, sleep problems were positively correlated with behavioral health symptoms. Importantly, leader promotion of healthy sleep was positively correlated with more sleep and negatively correlated with sleep problems and behavioral health symptoms. Insufficient sleep in the military is ubiquitous, with serious implications for the behavioral health and functioning of service members. Leaders should attend to these risks and examine ways to promote healthy sleep in service members.

Using a Workplace Rehabilitation and Reintegration Program Tracker Tool to Explore Factors Associated With Return to Duty Among Ill/Injured Military Personnel: A Preliminary Analysis.

INTRODUCTION: A great deal of time and resources have been spent on developing and implementing evidence-based return to work programs over the past few decades, compelling researchers to better understand the factors associated with more favorable outcomes. Using data collected as part of a participant tracking system trial for the Canadian Armed Forces (CAF) Return to Duty (RTD) program, analyses were conducted to better understand the trajectories of program participants and identify the factors associated with RTD. MATERIALS AND METHODS: Participants included 205 Regular Force CAF members from a single military base located in Eastern Canada who entered the RTD program during the trial period between April 2018 and March 2020. The health condition they were facing was mostly recent (i.e., onset within the past 6 months; 43%) and involved their mental health (67%). Data were collected on various demographic, military, health, and program characteristics using the RTD Data Collection Tool, which was updated periodically by program coordinators. Using data gathered by the Tool, a cumulative incidence function was generated to estimate the overall marginal probability of RTD over the duration of the program. Associations between RTD and a range of factors that were captured using the Tool were also examined in a series of competing-risks regressions. RESULTS: Findings indicated that the rate of RTD among program participants increased at around 3 months and began to level off around 9 months, suggesting that the likelihood of RTD after this window is diminished. Of the many factors that were considered, only years of service and work placement status at 3 months were found to be associated with RTD. Specifically, lower rates of RTD were observed among participants with 15 or more years of service compared to those with less than 5 years of service in the CAF and among those who were not yet assigned a work placement at 3 months relative to those who were. CONCLUSION: This study represents a first step in addressing the gap in our current knowledge about the characteristics of CAF members participating in the RTD program and the factors associated with RTD. Several recommendations are made for improving the participant tracking system in view of enhancing the level and quality of information that is available to assess participants' trajectories and inform further development of the program.

A moderated-mediation analysis of pathways in the association between Veterans' health and their spouse's relationship satisfaction: The importance of social support.

Introduction: Military personnel and Veterans are at increased risk of mental and physical health conditions, which can impact their families. Spouses often perform a vital role in caring for service members and Veterans facing illness or injury, which can lead to caregiver burden. In turn, this may contribute to relationship issues. Research suggests that ensuring that spouses are well supported can alleviate some of these negative effects. The current study examined whether social support received by spouses of newly released Veterans buffers the impact of Veterans' health on caregiver burden, subsequently impacting spouses' relationship satisfaction. Methods: Data were collected as part of the Canadian Armed Forces Transition and Well-being Survey. The sample included N = 595 spouses of Regular Force Veterans who released in 2016 with at least 2 years of service. We examined Veterans' mental and physical health and spouses' caregiver burden, social support, and relationship satisfaction. A moderated mediation model was tested using structural equation modeling. Results: There was a significant indirect association between Veterans' health (both physical and mental) and spouses' relationship satisfaction through caregiver burden. Furthermore, social support moderated the association, as evidenced by a weaker association between Veterans' health and caregiver burden at low levels (-1SD) of social support compared to high levels (+1SD). Implications: Findings suggest additional efforts should be made to ensure sufficient support is provided to spouses, especially when they are caring for a service member or Veteran facing illness or injury, to strengthen their families' well-being.

The Wahls Behavior Change Model for Complex Chronic Diseases: A Clinician's Guide.

Behavior change models are used to understand and intervene on health-related behaviors and outcomes. However, there is a gap in the literature regarding how to create and maintain behavior change in patients with complex chronic diseases such as Multiple Sclerosis (MS). To address this gap, the Wahls Behavior ChangeTM Model (WBCM) (The trademark applies to subsequent mention of the model.) was developed based on existing behavior change theory, empirical evidence, and extensive clinical experience caring for patients with complex chronic diseases. A patient-centered, comprehensive, and multimodal approach, this model provides a framework for understanding and implementing lifestyle behavior change. The overall goals of this paper are to: (1) review existing behavior change theories; (2) introduce the WBCM, including the model's 11 Principles for behavior change in patients with complex chronic diseases; and (3) share how providers can be trained to implement the WBCM. The WBCM can potentially improve short- and longer-term function and quality of life outcomes for people with complex chronic diseases.

Trials and tribulations among members of Canada's Defence Team early in the pandemic: key insights from the COVID-19 Defence Team Survey. / Les défis auxquels ont fait face les membres de l'Équipe de la Défense du Canada au début de la pandémie : principales conclusions du sondage de l'Équipe de la Défense sur la COVID-19.

INTRODUCTION: Due to the unprecedented impact of COVID-19, there is a need for research assessing pandemic-related challenges and stressors. The current study aimed to assess key concerns and general well-being among members of Canada's Defence Team, including Canadian Armed Forces personnel and members of the Department of National Defence (DND) Public Service. METHODS: The COVID-19 Defence Team Survey was administered electronically to Defence Team staff in April and May of 2020 and was completed by 13 688 Regular Force, 5985 Reserve Force and 7487 civilian DND Public Service personnel. Along with demographic information, the survey included assessments of work arrangement, pandemic-related concerns, general well-being and social and organizational support. Weighted data (to ensure representation) were used in all analyses. RESULTS: The majority of respondents were working from home, with a small minority unable to work due to restrictions. Though many concerns were endorsed by a substantial proportion of respondents, the most prevalent concerns were related to the health and well-being of loved ones. The majority of respondents reported their partner, family, supervisors, friends, colleagues and children provided general support. Half of the civilian defence staff and one-third of military respondents reported a decline in mental health. Women, younger respondents, those with dependents and, in some cases, those who were single without children were at risk of lower well-being. CONCLUSION: The pandemic has negatively impacted a substantial portion of the Defence Team. When responding to future crises, it is recommended that leaders of organizations provide additional supports to higher-risk groups and to supervisors who are ideally positioned to support employees during challenging times.

Well-being of Canadian Armed Forces members during the COVID-19 pandemic: the influence of positive health behaviours. / Bien-être des membres des Forces armées canadiennes pendant la pandémie de COVID-19 : influence des comportements propices à la santé.

INTRODUCTION: The COVID-19 pandemic has been linked to increased depression, anxiety and other adverse mental health outcomes. Understanding the behaviours that positively influence health is important for the development of strategies to maintain andimprove well-being during the pandemic. METHODS: This study focussed on Canadian Armed Forces Regular Force members (N = 13 668) who participated in the COVID-19 Defence Team Survey, administered between April and May 2020. The use of positive health behaviours and the extent to which such behaviours were associated with anxiety, depression and self-reported change in health and stress levels compared to before the pandemic were examined. RESULTS: Depression and anxiety were experienced by 14% and 15% of the sample, respectively, while 36% reported that their mental health had gotten worse since the pandemic started, and close to half reported worse physical health and stress levels. The most common behaviours respondents reported engaging in to maintain or improve their health were exercising outdoors, healthy eating and connecting with loved ones. Although most behaviours were associated with better health outcomes, meditation and connecting with loved ones showed associations with worse health. CONCLUSION: Engaging in behaviours such as exercise and healthy eating was generally associated with better health outcomes. Unexpected relationships of meditation and connecting with loved ones are discussed in terms of their use in stressful times among those with mental health issues, past research on coping strategies and impacts of the pandemic and physical distancing on social connections. The findings may have implications for strategies to promote healthy behaviours during the remainder of the pandemic and similar crises in the future.

Adverse childhood experiences and mental health in military recruits: Exploring gender as a moderator.

Adverse childhood experiences (ACEs) have consistently been associated with adult psychopathology and are commonly reported among military populations, with women more likely to report many types of ACEs than men. Limited research has examined the role of gender in the association between ACEs and mental health in military populations. The current study assessed the significance of gender differences in ACEs and mental health and explored the associations among these variables in a sample of Canadian Armed Forces recruits/officer cadets. Analyses with cross-sectional Recruit Health Questionnaire (RHQ) data from 50,603 recruits/officer cadets indicated that women were more likely to report witnessing domestic violence, experiencing sexual abuse, and living with someone with mental health problems or alcohol misuse, odds ratios (ORs) = 1.22-4.35, ps < .001. Women were more likely to screen positive for depression, adjusted (aORs) = 1.25-1.49, p < .001-p = .002, and anxiety, aORs = 2.00-2.33, ps < .001, before basic military training. ACEs were associated with screening positive for probable mental health conditions, aORs = 1.54-6.13, p < .001-p = .017. A significant interaction suggested the association between childhood sexual abuse and depression was stronger for men, aOR = 2.49, p < .001, than women, aOR = 1.63, p = .002, as was the association between childhood sexual abuse and posttraumatic stress disorder, men: aOR = 6.06, p < .001, women: aOR = 3.36, p < .001. These results underscore the importance of considering gender and childhood trauma in mental health interventions with military personnel.

Reducing Disparities: A Virtual Quality Improvement Collaborative Resulted in Better Health Outcomes for 4 Target Populations Disproportionately Affected by HIV.

CONTEXT: Although viral suppression rates have recently increased among people with HIV, specific populations still experience disparities in health outcomes, a priority in the national response to end the HIV epidemic. PURPOSE: The end+disparities ECHO Collaborative, a quality improvement initiative among HIV providers in the United States from June 2018 to December 2019, created virtual communities of practice to measurably increase viral suppression rates in populations disproportionately affected by HIV: men who have sex with men of color, Black/African American and Latina women, youth aged 13 to 24 years, and transgender people. METHODS: Participating Ryan White HIV/AIDS Program-funded providers prioritized their improvement efforts to focus on one target population and joined virtual affinity sessions with other providers focused on that population for guidance by subject matter experts and exchanges with peer providers. During 9 submission cycles, providers reported their viral suppression data for the preceding 12 months. MAIN OUTCOME MEASURES: The principal outcome measures were changes in viral suppression rates among 4 target populations and changes in viral suppression gaps compared with the rest of HIV-infected patients served by the same agency. RESULTS: A total of 90 providers were included in the data analyses with an average of 110 775 reported patients, out of which 19 442 represented the targeted populations. The average viral suppression rates for agency-selected populations increased from 79.2% to 82.3% (a 3.9% increase), while the remaining caseload increased at a lower rate from 84.9% to 86.1% (a 1.4% increase). The viral suppression gap was reduced from 5.7% to 3.8%, a 33.5% reduction. Improvements were found across all target populations. CONCLUSIONS: The collaborative demonstrated improved health outcomes and reductions in HIV-related health disparities, moving toward ending the HIV epidemic. The model of utilizing low-cost videoconferencing technologies to create virtual communities of learning is well suited to mitigate other disease-related disparities, nationally and abroad.

Unilateral angioedema.

Angiotensin converting enzyme inhibitor-induced angioedema is typically easily recognizable in the emergency department. Angioedema lateralizing to one side, however, is infrequently reported, rare, and has the same potential of progression to airway compromise. We present of a case of an 80-year-old man with angioedema of the lower lip that had regressed prior to significant progression of right sided angioedema of the tongue and oropharynx.

Pandemic-Related Challenges and Organizational Support Among Personnel in Canada's Defense Establishment.

In the final week of March 2020, 2.8 million Canadians were away from their usual places of work and engaging in remote and/or telework to mitigate the spread of COVID-19 (Statistics Canada, 2020). The Government of Canada's Department of National Defence (DND) and the Canadian Armed Forces (CAF) were no exception, with most members from the regular force (Reg F), the primary reserve force (P Res), and the DND public service (DND PS) working from home. The COVID-19 Defence Team Survey was administered from April 29th, 2020, and May 22nd, 2020, to gain insight into work, health, and family-related challenges since the onset of the pandemic and change in work arrangements. Responses from five open-ended questions were qualitatively analyzed to determine general themes of concern regarding work, personal, and family related challenges, stress-management and coping strategies, and recommendations for improving the work situation and personal well-being. Given the different roles and conditions of employment, responses of the different groups or "components" of respondents (Reg F, P Res, DND PS) were compared to identify common and unique challenges to inform targeted organizational responses. A total of 26,207 members (Reg F = 13,668, 52.2%; P Res = 5,052, 19.3%; DND PS = 7,487, 28.6%) responded to the survey's five open-ended questions, which yielded a total of 75,000 open-ended responses. When asked about work-related challenges, respondents' most common challenges included dissatisfaction with technology/software, work arrangements, ergonomics, work-life balance, communication within the organization, and the uncertainties regarding career development. In terms of personal and/or family-related challenges, the most common challenges included social isolation, the impact of the pandemic on mental health, school closures and homeschooling, caring for vulnerable family members, and childcare concerns. The most common stress-management and coping strategies included exercise, spending time outdoors, communicating or spending time with family members, household chores/projects, mind-body wellness exercises, and playing games. The most common recommendations made by respondents to improve their work- or personal-related situations included improving technological capabilities, streamlining communication, providing hardware and software necessary to ensure comfortable ergonomics, the provision of flexibility in terms of telework schedules, return-to-work decisions, and the expansion of benefits and access to childcare services. In terms of differences among the components, DND PS personnel were most likely to report dissatisfaction with technological changes and ergonomics, and to recommend improving these technological limitations to maximize productivity. Reg F members, on the other hand, were most likely to recommend increased support and access to childcare, and both Reg F and P Res members were more likely to mention that increased benefits and entitlements in response to the COVID-19 pandemic would be ameliorative. The results of this study highlight several important facts about the impact of the COVID-19 pandemic on personnel working in large, diverse organizations. For example, advancements in organizational technological capabilities were highlighted herein, and these are likely to grow to maintain productivity should remote work come to be used more extensively in the long-term. This study also highlighted the importance of flexibility and accommodation in relation to individual needs - a trend that was already underway but has taken on greater relevance and urgency in light of the pandemic. This is clearly essential to the organization's role in supporting the well-being of personnel and their families. Clear and streamlined communication regarding organizational changes and support services is also essential to minimize uncertainty and to provide useful supports for coping with this and other stressful situations.

A Modified MCT-Based Ketogenic Diet Increases Plasma ß-Hydroxybutyrate but Has Less Effect on Fatigue and Quality of Life in People with Multiple Sclerosis Compared to a Modified Paleolithic Diet: A Waitlist-Controlled, Randomized Pilot Study.

OBJECTIVE: To investigate the feasibility of a modified MCT-based ketogenic diet and its impact on plasma ß-hydroxybutyrate and MS outcomes compared to a modified Paleolithic diet and usual diet in people with Multiple Sclerosis (MS). METHODS: Fifteen individuals with MS were randomized to 3 groups: 1) modified Paleolithic diet (Paleo; n = 6); 2) medium-chain triglyceride (MCT)-based ketogenic diet that included coconut as a fat source (Keto; n = 5); or 3) usual diet (Control; n = 4). Participants had blood drawn every 4 weeks to monitor nutritional ketosis. Participants completed 4-day weighed food records, measures of disability, fatigue, quality of life (QoL), cognitive function, and physical function at baseline and 12-weeks. RESULTS: Macronutrient intake significantly shifted toward a ratio indicative of a ketogenic diet in the Keto group at 12 weeks. Similarly, plasma ß-hydroxybutyrate indicated nutritional ketosis in the Keto group, whereas neither macronutrient intake nor plasma ß-hydroxybutyrate indicated nutritional ketosis in the Paleo and Control groups. The Paleo group had significant within group reductions in fatigue scores and maintained cognitive function scores compared to the Control group. The Keto group had significant reductions in fasting glucose and insulin compared to baseline values; however, no clinical outcomes significantly changed. CONCLUSIONS: Participants consuming the MCT-based ketogenic diet achieved nutritional ketosis; however, it was not associated with significant clinical improvement in this study whereas the modified Paleolithic diet was associated with significant clinical improvements. Larger randomized controlled trials are needed to determine the safety and efficacy of the modified Paleolithic and MCT-based ketogenic diets on MS.

Validation of a general mental health self-efficacy assessment tool.

The aim of this study was to assess the validity of a 14-item mental health self-efficacy scale developed to assess the effectiveness of the Road to Mental Readiness (R2MR) - a program aimed at improving the well-being and mental health of Canadian Armed Forces (CAF) personnel. The validity of the scale was assessed through an analysis of data collected as part of a pilot study and a larger group randomized control trial (GRCT) on the effectiveness of R2MR administered to CAF noncommissioned member recruits during basic training. Using data collected for the pilot study (N = 276), an initial review of items indicated a need to eliminate two redundant items and two items that were weakly correlated with other scale items. A parallel analysis and exploratory factor analysis (EFA) conducted on the resulting 10-item scale pointed to a one-factor model with all items loading satisfactorily. Using data from the GRCT (N = 1962), a confirmatory factor analysis (CFA) was conducted to further assess the revised scale. This CFA suggested good model fit (Root Mean Square Error of Approximation of .07 and Standardized Root Mean Square Residual of .06). The revised scale had an alpha of .88, was very strongly correlated with the full scale (r = .97, p < .001), and significantly predicted perceived control and self-efficacy regarding accessing mental health care and intention to access care.

Multisensory Sensitivity is Related to Deep-Tissue but Not Cutaneous Pain Sensitivity in Healthy Individuals.

PURPOSE: Some individuals with chronic pain find daily life sensations (eg, noise, light, or touch) aversive. This amplification of multisensory sensations has been associated with centrally mediated plasticity; for example, greater multisensory sensitivity (MSS) occurs in patients with fibromyalgia than rheumatoid arthritis. However, whether MSS preferentially relates to pain measures which reflect central influences (eg, dynamic quantitative sensory testing (QST) or referred pain), or whether the MSS-pain relationship requires priming from chronic pain, is unknown. Thus, this cross-sectional study investigated the relationships between MSS assessed in a pain-free state and evoked pain sensitivity. METHODS: Experimental intramuscular infusion pain and multiple static and dynamic QST were assessed in 465 healthy, pain-free adults: pain thresholds using pressure (PPTs) and heat (HPTs), temporal summation of pain (TSP) using pressure, heat or punctate stimuli, and conditioned pain modulation (CPM) using pressure or heat test stimuli. MSS was assessed using 7 items from Barsky's Somatosensory Amplification Scale. Differences in pain and QST between sex-specific MSS quartiles were assessed, adjusting for multiple comparisons. All participants completed at least one intramuscular infusion condition, but not all were asked to complete each QST (n=166-465). RESULTS: Both static and dynamic QST differed between highest and lowest MSS quartiles using pressure stimuli: lower PPTs (adjusted-p<0.01); increased pressure TSP (adjusted-p=0.02); lower pressure CPM (adjusted-p=0.01). However, none of the heat or punctate QST measures (HPTs, TSP, or CPM) differed between MSS quartiles (adjusted-p>0.05). Odds of experiencing TSP or referred pain was not greater, whereas CPM was 8-fold less likely, in those with highest MSS. CONCLUSION: Normal variation in non-noxious MSS is related to both static and dynamic pain sensitivity, without sensitization associated with chronic pain, but is dependent on the QST stimulus. Thus, common influences on MSS and pain sensitivity may involve central mechanisms but are likely more complex than previously recognized.

The Mediating Role of Alexithymia in the Association Between Adverse Childhood Experiences and Postdeployment Mental Health in Canadian Armed Forces Personnel.

Recent studies showing an association between adverse childhood experiences and the development of alexithymia in military personnel have generated interest regarding the role of alexithymia in the pathway linking childhood trauma exposure to mental health disorders. Accordingly, the current study was conducted to (a) examine the associations among adverse childhood experiences, alexithymia, and symptoms of depression and posttraumatic stress disorder (PTSD) among recently deployed Canadian military personnel and (b) assess the mediating role of alexithymia in these associations. Data collected from 2,927 members of the Canadian Armed Forces at baseline and after their return from an overseas deployment were subjected to a prospective path analysis. The results of the path analysis, R2 = .35, pointed to a significant direct effect of childhood adversity on postdeployment mental health symptoms. Contrary to our expectations, the results also pointed to a negative indirect effect of childhood neglect, suggesting that childhood neglect contributed to lower levels of postdeployment depression and PTSD symptoms through the dimension of alexithymia related to difficulty in describing feelings. These patterns of associations, for the most part, persisted even when accounting for combat exposure during recent deployments, R2 = .42. The present results are discussed in light of study limitations and methodological considerations, and policy and clinical implications are noted.

Factor structure of a coping measure in the 2013 Canadian Forces Mental Health Survey.

BACKGROUND: Coping has been the subject of numerous studies over the past decades, yet significant debate remains regarding the structure of this construct. DATA AND METHODS: Exploratory and confirmatory factor analyses were conducted on 2013 Canadian Forces Mental Health Survey (CFMHS) data to examine the factor structure of coping items. A total of 6,696 Canadian Armed Forces (CAF) Regular Force members completed a coping inventory that assessed 14 coping strategies (e.g., problem solving, talking to others). RESULTS: Results indicated that coping among CAF Regular Force members was best represented by two factors: positive coping and negative coping. Coping strategies categorized as positive coping included active efforts to confront the stressor or improve one's well-being, whereas those categorized as negative coping reflected passive or avoidant efforts or behaviours that may compromise one's health. Positive coping factor scores were positively associated with perceptions of one's ability to handle difficult problems and day-to-day demands, while negative coping factor scores were negatively associated with such perceptions, suggesting that the factors had good concurrent validity. Additional analyses pointed to higher positive and negative coping scores among female Regular Force members compared with male Regular Force members. The additional analyses also showed generally less favourable coping scores among lower-ranking Regular Force members and those with a history of deployment to Afghanistan relative to their respective counterparts. Lastly, Regular Force members who received mental health training demonstrated higher positive coping scores. DISCUSSION: The report discusses implications for the use of coping indicators in future analyses involving the CFMHS.

Transcutaneous Electrical Nerve Stimulation Reduces Resting Pain in Head and Neck Cancer Patients: A Randomized and Placebo-Controlled Double-Blind Pilot Study.

BACKGROUND: Individuals receiving radiation for head and neck cancer (HNC) often develop painful oral mucositis that impairs function, possibly leading to feeding tubes, hospitalization, and treatment delays. Although pharmacologic medications provide some relief, many report inadequate analgesia and adverse effects. Transcutaneous electrical nerve stimulation (TENS) is a safe, nonpharmacologic intervention; it decreases pain and analgesics and improves function, yet no studies examined TENS for HNC. OBJECTIVE: The aim of this study was to examine the efficacy of TENS for pain and function in HNC patients. METHODS: This study used a randomized, double-blinded crossover design; participants received 3 TENS treatments during weeks 4 to 6 of radiation: active, placebo, and no TENS over the temporomandibular joint and upper cervical region. Pain (McGill Pain Questionnaire, visual analog scale [VAS] resting and function), function (mouth opening, tongue movement, speaking), fatigue (VAS), and treatment effectiveness (VAS) were assessed before and after TENS at 3 visits. RESULTS: Resting pain (McGill Pain Questionnaire and VAS) decreased significantly more after active TENS than placebo or no TENS; changes in function and pain with function did not differ between conditions. Active TENS decreased fatigue significantly more than no TENS and was rated as more effective than placebo TENS. CONCLUSION: Transcutaneous electrical nerve stimulation improves pain in HNC patients receiving radiation but not function or pain with function relative to placebo or no TENS. IMPLICATIONS FOR PRACTICE: Transcutaneous electrical nerve stimulation may be a viable tool for radiation-induced HNC pain to complement pharmacologic approaches. This nonpharmacologic intervention could decrease the debilitating effects of radiation and analgesics, and improve quality of life. Clinical trials should examine the effects and safety of repeated, daily TENS in HNC patients receiving radiation.

Deployment-related trauma and post-traumatic stress disorder: does gender matter?

Objective: Military research has attempted to identify whether women have an increased vulnerability to mental health issues following deployment-related trauma, but findings have been mixed. Most studies have controlled for childhood abuse, but not other non-deployment trauma (e.g. life-threatening illness), which may partly explain previous mixed results. This study assessed gender differences in the association between deployment-related trauma and post-traumatic stress disorder (PTSD) while controlling for non-deployment trauma. Methods: Data came from the 2013 Canadian Forces Mental Health Survey. Regular or reserve personnel who had been deployed at least once were included in this study (n = 5980). Logistic regression was used to examine the interaction between gender and deployment-related trauma in predicting lifetime PTSD. Results: After controlling for non-deployment trauma, the association of gender with PTSD went from being significant to being marginally significant. The interaction between gender and deployment-related trauma was not significant. Conclusion: Though controlling for non-deployment trauma did not completely dissipate gender differences in PTSD, such differences were greatly reduced, indicating that these may be partly related to traumatic experiences outside deployment. As gender did not moderate the link between deployment-related trauma and PTSD, the findings suggest that trauma experienced while on deployment does not disproportionately affect women compared to their male counterparts.

Objetivo: La investigación militar ha intentado identificar si las mujeres tienen una mayor vulnerabilidad a los problemas de salud mental después del trauma relacionado con el despliegue militar, pero los hallazgos han sido mixtos. La mayoría de los estudios han controlado el abuso infantil, pero no otros traumas no relacionados con el despliegue (p. Ej., Enfermedad potencialmente mortal), lo cual puede explicar parcialmente los resultados mixtos anteriores. Este estudio evaluó las diferencias de género en la asociación entre el trauma relacionado con el despliegue militar y el trastorno de estrés postraumático, al mismo tiempo que se controlaba los traumas no relacionados con despliegue militar.Métodos: Los datos provienen de la Encuesta de Salud Mental de las Fuerzas Armadas Canadienses de 2013. El personal regular o de reserva que se había desplegado al menos una vez se incluyeron en este estudio (n = 5980). Se Utilizó regresión logística para examinar la interacción entre el género y el trauma relacionado con el despliegue en la predicción del TEPT a lo largo de la vida.Resultados: Después de controlar por trauma no relacionado con el despliegue, la asociación de género con TEPT paso de ser significativa a solo marginalmente significativa. La interacción entre el género y el trauma relacionado con el despliegue no fue significativa.Conclusión: Aunque el controlar por traumas no relacionados con el despliegue militar no disipó por completo las diferencias de género en el TEPT, tales diferencias se redujeron sustancialmente, lo que indica que pueden estar parcialmente relacionadas con experiencias traumáticas fuera del despliegue. Dado que el género no moderó la relación entre el trauma relacionado con el despliegue y el TEPT, los hallazgos sugieren que el trauma experimentado durante el despliegue no afecta en forma desproporcionada a las mujeres en comparación con sus pares masculinos.

Spinal-induced hypotension: Incidence, mechanisms, prophylaxis, and management: Summarizing 20 years of research.

Hypotension commonly occurs in parturients undergoing cesarean delivery under spinal anesthesia. This leads to maternal and neonatal adverse outcomes, including maternal nausea and vomiting and fetal acidosis, and might even lead to cardiovascular collapse if not treated. Arterial dilatation and reduction in systemic vascular resistance are the major contributors to spinal-induced hypotension. Therefore, strategies aimed at expanding the intravascular volume with fluid loading or increasing venous return with lower extremities mechanical compression and lateral tilt have had limited effectiveness in the management of spinal-induced hypotension. Vasopressors are therefore the mainstay for the prophylaxis and treatment of spinal-induced hypotension. Phenylephrine is associated with improved neonatal acid-base status and a lower risk of maternal nausea and vomiting compared with ephedrine and is now considered the vasopressor of choice in obstetric patients. This review discusses the various strategies for managing spinal-induced hypotension with a particular emphasis on the optimal use of vasopressors.
