Assessing Military Mental Health during the Pandemic: A Five Country Collaboration.

PURPOSE OF REVIEW: Members of a technical panel representing Australia, Canada, New Zealand, the UK, and the US collaborated to develop surveys designed to provide military leaders with information to guide decisions early in the COVID-19 pandemic. The goal of this paper is to provide an overview of this collaboration and a review of findings from the resulting body of work. RECENT FINDINGS: While surveys pointed to relatively favorable mental health and perceptions of leadership among military personnel early in the pandemic, these observations did not reflect the experiences of personnel deployed in COVID-19 response operations, nor were these observations reflective of later stages of the pandemic. Establishing and leveraging networks that enable the rapid development of employee surveys and sharing of results can serve as a pathway for empowering military leaders in times of crisis. Organizational support and leadership decisions are especially critical for maintaining well-being among personnel during crises.

Building psychological resilience in Armed Forces worldwide.

Psychological resilience among troops can be enhanced through relatively simple interventions. Globally, various Armed Forces have successfully implemented modules for building psychological resilience. Programs from different countries are listed, evaluated and their underpinnings explored. Recommendations for a variety of feasible and culturally acceptable interventions targeted at individuals, families, units, community and organizations in the Indian context have been made; ranging from mindfulness training to embedded combat psychologists. Interventions are likely to succeed if integrated within existing basic training and unit/career programs.

Prevalence and Correlates of Military Sexual Trauma in Service Members and Veterans: Results From the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey.

INTRODUCTION: Military sexual trauma (MST) is an ongoing problem. We used a 2002 population-based sample, followed up in 2018, to examine: (1) the prevalence of MST and non-MST in male and female currently serving members and veterans of the Canadian Armed Forces, and (2) demographic and military correlates of MST and non-MST. METHODS: Data came from the 2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (n = 2,941, ages 33 years + ). Individuals endorsing sexual trauma were stratified into MST and non-MST and compared to individuals with no sexual trauma. The prevalence of lifetime MST was computed, and correlates of sexual trauma were examined using multinomial regression analyses. RESULTS: The overall prevalence of MST was 44.6% in females and 4.8% in males. Estimates were comparable between currently serving members and veterans. In adjusted models in both sexes, MST was more likely among younger individuals (i.e., 33-49 years), and MST and non-MST were more likely in those reporting more non-sexual traumatic events. Among females, MST and non-MST were more likely in those reporting lower household income, non-MST was less likely among Officers, and MST was more likely among those with a deployment history and serving in an air environment. Unwanted sexual touching by a Canadian military member or employee was the most prevalent type and context of MST. INTERPRETATION: A high prevalence of MST was observed in a follow-up sample of Canadian Armed Forces members and veterans. Results may inform further research as well as MST prevention efforts.

Military veterans and civilians' mental health diagnoses: an analysis of secondary mental health services.

PURPOSE: Healthcare provision in the United Kingdom (UK) falls primarily to the National Health Service (NHS) which is free at the point of access. In the UK, there is currently no national marker to identify military veterans in electronic health records, nor a requirement to record it. This study aimed to compare the sociodemographic characteristics and recorded mental health diagnoses of a sample of veterans and civilians accessing secondary mental health services. METHODS: The Military Service Identification Tool, a machine learning computer tool, was employed to identify veterans and civilians from electronic health records. This study compared the sociodemographic characteristics and recorded mental health diagnoses of veterans and civilians accessing secondary mental health care from South London and Maudsley NHS Foundation Trust, UK. Data from 2,576 patients were analysed; 1288 civilians and 1288 veterans matched on age and gender. RESULTS: Depressive disorder was the most prevalent across both groups in the sample (26.2% veterans, 15.5% civilians). The present sample of veterans accessing support for mental health conditions were significantly more likely to have diagnoses of anxiety, depressive, psychosis, personality, and stress disorders (AORs ranging 1.41-2.84) but less likely to have a drug disorder (AOR = 0.51) than age- and gender-matched civilians. CONCLUSION: Veterans accessing secondary mental health services in South London had higher risks for many mental health problems than civilians accessing the same services. Findings suggest that military career history is a key consideration for probable prognosis and treatment, but this needs corroborating in other geographical areas including national population-based studies in the UK.

Problem drinking recognition among UK military personnel: prevalence and associations.

PURPOSE: Despite the higher prevalence of problem drinking in the UK military compared to the general population, problem recognition appears to be low, and little is known about which groups are more likely to recognise a problem. This study examined prevalence of problem drinking recognition and its associations. METHODS: We analysed data from 6400 regular serving and ex-serving personnel, collected in phase 3 (2014-2016) of the King's Centre for Military Health Research cohort study. MEASUREMENTS: Participants provided sociodemographic, military, health and impairment, life experiences, problem drinking, and problem recognition information. Problem drinking was categorised as scores ≥ 16 in the AUDIT questionnaire. Associations with problem recognition were examined with weighted logistic regressions. FINDINGS: Among personnel meeting criteria for problem drinking, 49% recognised the problem. Recognition was most strongly associated (ORs ≥ 2.50) with experiencing probable PTSD (AOR = 2.86, 95% CI = 1.64-5.07), social impairment due to physical or mental health problems (AOR = 2.69, 95% CI = 1.51-4.79), adverse life events (AOR = 2.84, 95% CI = 1.70-4.75), ever being arrested (AOR = 2.99, CI = 1.43-6.25) and reporting symptoms of alcohol dependence (AOR = 3.68, 95% CI = 2.33-5.82). To a lesser extent, recognition was also statistically significantly associated with experiencing psychosomatic symptoms, feeling less healthy, probable common mental health disorders, and increased scores on the AUDIT. CONCLUSION: Half of UK military personnel experiencing problem drinking does not self-report their drinking behaviour as problematic. Greater problem drinking severity, poorer mental or physical health, and negative life experiences facilitate problem recognition.

Personal health monitoring in the armed forces - scouting the ethical dimension : A case study in the Netherlands Armed Forces during the Covid-19 pandemic.

BACKGROUND: The field of personal health monitoring (PHM) develops rapidly in different contexts, including the armed forces. Understanding the ethical dimension of this type of monitoring is key to a morally responsible development, implementation and usage of PHM within the armed forces. Research on the ethics of PHM has primarily been carried out in civilian settings, while the ethical dimension of PHM in the armed forces remains understudied. Yet, PHM of military personnel by design takes place in a different setting than PHM of civilians, because of their tasks and the context in which they operate. This case study therefore focusses on obtaining insights into the experiences and related values of different stakeholders regarding an existing form of PHM, the Covid-19 Radar app, in the Netherlands Armed Forces. METHODS: We carried out an exploratory qualitative study, using semi-structured interviews with twelve stakeholders in the Netherlands Armed Forces. We focussed on participation in the use of PHM, reflections on the practical use and use of data, moral dilemmas and the need for ethics support, all in regard to PHM. The data was analysed using an inductive thematic approach. RESULTS: Three interlinking categories reflecting ethical dimensions of PHM emerged: (1) values, (2) moral dilemmas, and (3) external norms. The main values identified were: security (in relation to data), trust and hierarchy. Multiple related values were found. Some, but no broadly shared, moral dilemmas were identified and no strong need for ethics support was expressed. CONCLUSION: This study shed light on key values, provide insights in the experienced and presumed moral dilemmas and bring to mind ethics support considerations when looking at PHM in the armed forces. Some values bring a certain vulnerability to military users when personal and organisational interests are not aligned. Furthermore, some identified values may hinder a careful consideration of PHM because they potentially conceal parts of ethical dimensions of PHM. Ethics support can assist in uncovering and addressing these concealed parts. The findings highlight a moral responsibility for the armed forces to devote attention to the ethical dimensions of PHM.

Sleep duration, sleep quality and obesity in the Canadian Armed Forces.

Background: Research has identified an association between sleep and obesity in the general population. It is also important to examine this association in a military population. Data and methods: Data from the 2019 Canadian Armed Forces Health Survey (CAFHS) were used to estimate the prevalence of sleep duration, sleep quality characteristics, overweight and obesity for Regular Force members. The relationship of sleep duration and sleep quality with obesity was assessed with multivariable logistic regression that controlled for sociodemographic, work and health characteristics. Results: Females were significantly more likely than males to report meeting recommended sleep duration (7 hours to less than 10 hours; 48.7% vs. 40.4%), trouble falling or staying asleep (32.3% vs. 23.5%), or that sleep was not refreshing (64.0% vs. 57.7%). Difficulty staying awake did not differ significantly between males and females (6.3% vs. 5.4%). Obesity, but not being overweight, was significantly more prevalent among those who had short (less than 6 hours) or borderline (6 hours to less than 7 hours) sleep duration, or poor sleep quality. Compared with recommended sleep duration, short sleep duration (adjusted odds ratio [AOR] 1.3; 95% confidence interval [CI]: 1.2 to 1.6) and borderline sleep duration (AOR 1.2; 95% CI: 1.1 to 1.4) were associated with obesity for males, but not females, in fully controlled models. Sleep quality indicators were not independently associated with obesity. Interpretation: This study adds to the body of evidence that identifies an association between sleep duration and obesity. The results emphasize the importance of sleep as one of the components of the Canadian Armed Forces Physical Performance Strategy.

Recruiting Military Veterans into Alcohol Misuse Research: The Role of Social Media and Facebook Advertising.

Background: The use of digital technology within health care service delivery, monitoring, and research is becoming progressively popular, particularly given the ongoing COVID-19 pandemic. Mobile health (m-health) apps, one form of digital technology, are increasingly being used to promote positive health related behavior change. Therefore, it is important to conduct research to understand the efficacy of m-health apps. The process of participant recruitment is an essential component in producing strong research evidence, along with ensuring an adequately powered sample to conduct meaningful analyses and draw robust conclusions. Methods: In this work we outline and reflect on the strategies used to recruit help-seeking military veterans into an intervention study, which aimed to evaluate the efficacy of an app (Drinks:Ration) to modify behavior in alcohol misusers. Recruitment strategies included through (1) partner organizations and (2) social media and Facebook advertising (ads). Results: Facebook ads were live for a period of 88 days and were viewed by a total audience of 29,416 people. In total 168 military veterans were recruited across all recruitment strategies, meaning that Drinks:Ration exceeded its recruitment targets. Half of the sample (n = 84) were recruited through social media, including Facebook ads. Conclusions: The current article highlighted that targeted Facebook ads were an efficient strategy to recruit military veterans into a digital intervention trial aiming to reduce alcohol consumption because they reduced the amount of time and resources required to contact a large number of potentially eligible individuals for our study. This article acts as a starting point for other researchers to evaluate their recruitment pathways for recruiting military veterans into alcohol misuse research.

Adjustment disorder in the Armed Forces: a systematic review.

BACKGROUND: In the UK military, adjustment disorder (AjD) is reported as one of the most diagnosed mental disorders, alongside depression, in personnel presenting to mental health services. Despite this, little is understood about what may predict AjD, common treatment or outcomes for this population. AIM: The systematic review aimed to summarise existing research for AjD in Armed Forces (AF) populations, including prevalence and risk factors, and to outline clinical and occupational outcomes. METHOD: A literature search was conducted in December 2020 to identify research that investigated AjD within an AF population (serving or veteran) following the PRISMA guidelines. RESULTS: Eighty-three studies were included in the review. The AjD prevalence estimates in AF populations with a mental disorder was considerably higher for serving AF personnel (34.9%) compared to veterans (12.8%). Childhood adversities were identified as a risk factor for AjD. AjD was found to increase the risk of suicidal ideation, with one study reporting a risk ratio of 4.70 (95% Confidence Interval: 3.50-6.20). Talking therapies were the most common treatment for AjD, however none reported on treatment effectiveness. CONCLUSION: This review found that AjD was commonly reported across international AF. Despite heterogeneity in the results, the review identifies several literature gaps.

Immunohaematological conundrums in obstetrics from transfusion services viewpoint in Armed Forces setup.

Background: Obstetrics as a speciality has a very long association with the transfusion services and poses its own set of immunohematological (IHL) challenges. A study was carried out to evaluate the spectrum of IHL issues in obstetrics in our setup and to suggest a way forward. Methods: This study was carried out in a transfusion services setup catering to antenatal care (ANC) clientele in two tertiary-level health care setups. Samples were collected from all ANC patients requiring transfusion and patients reporting for Indirect Coombs Test (ICT). Data included ICT positive cases with implicated alloantibodies, those requiring specialised procedures and the foetal outcome. The results were described using descriptive statistics by frequencies and percentages. Results: A total of 4683 eligible samples were included in the study, out of 21,893 antenatal patients visiting our setup during study period. One hundred thirty-six ANC patient samples were found to be ICT positive. The most common single alloantibody was anti-D (n = 77, 57.5%). Double antibody positivity was found in 28 patients. Multiple alloantibodies were found in 1 patient. Up to 48% of these allo-anti D cases necessitated specialised procedures. Conclusion: The IHL issues of obstetrics faced in our setup are no less than that in Indian population. We have much higher frequency of double alloantibody in our ANC population. The authors propose that all multiparous ANC patients, especially with a history of transfusion, irrespective of Rh D status should be screened for irregular alloantibodies to circumvent these issues and the last-minute rush for provision of compatible units.

Cancer trends and burden among Armed Forces personnel, veterans and their families: Cancer registry data analysis from tertiary care hospital.

Background: Cancer incidence is rising across the globe. The incidence and patterns of various cancers among Armed Forces Personnel and Veterans is not known. We did the analysis of registry data maintained at our hospital. Methods: A retrospective analysis was performed of all patients registered at our hospital cancer registry between 01st January 2017 and 31st December 2019. Patients were registered with unique identification number. Baseline demographics and cancer subtype data were retrieved. Patients with histopathologically proven diagnosis and age ≥18 years were studied. Armed Forces Personnel (AFP) were defined as those who are in active service, and Veterans as those who had retired from service at the time of registration. Patients with Acute and Chronic Leukemias were excluded. Results: New cases registered were 2023, 2856 and 3057 in year 2017, 2018, 2019 respectively. AFP, Veterans and dependents among them were 9.6%, 17.8%, and 72.6% respectively. Haryana, Uttar Pradesh and Rajasthan represented 55% of all cases with male to female ratio 1.14:1 and median age was 59 years. The median age among AFP was 39 years. Among AFP as well as veterans, Head and Neck cancer was the most common malignancy. Cancer incidence was significantly higher in adults >40 years as compared to <40 years. Conclusion: Seven percent rise per year of new cases in this cohort is alarming. Tobacco-related cancers were the most common. There is an unmet need to establish a prospective centralized Cancer Registry to better understand the risk factors, outcomes of treatment and strengthen the policy matters.

Issues Related to Children-Faced by Armed Forces Families When Caring for Patients in Palliative Care - A Qualitative Study.

Objectives: Access to palliative care is limited, especially in rural India. Children needing care by palliative teams may themselves be patients, or siblings and children of patients. Armed forces families face characteristic lifestyle challenges - frequent transfers, living in difficult and remote areas, serving personnel staying apart from families for long periods - very different from issues faced by civilians. Military service increases the risk of psychosocial burden for serving personnel as well as families. Most depend on private and state medical services for palliative care so it is important for the palliative community to understand their issues. This study aimed to explore the issues related to children - faced by armed forces families when caring for patients in palliative care. Material and Methods: Qualitative study based on thematic analysis of semi-structured interviews with caregivers - either serving personnel or their dependents, in three centres. Results: Analysis of the 15 interviews showed that armed forces families face complex challenges related to children when caring for the palliative patient due to frequent movement, lack of paediatric palliative services in far-flung areas, disruption of the continuity of care, social isolation, language, and cultural barriers when living in non-native areas, inability to build and access family and community support and financial burden due to restrictive reimbursement policies. Conclusion: Although medical and administrative support within the organisation provides a cushion, wives have to manage alone in the father's prolonged absence, and safety is a concern for children when living outside the campuses and serving personnel report guilt, anger, and helplessness at not being present when needed. Awareness of these issues can enable palliative workers to provide more meaningful support tailored to the needs of service families.

Canadian Veteran chronic disease prevalence and health services use in the five years following release: a matched retrospective cohort study using routinely collected data.

BACKGROUND: Occupational exposures may result in Canadian military Veterans having poorer health and higher use of health services after transitioning to civilian life compared to the general population. However, few studies have documented the physical health and health services use of Veterans in Canada, and thus there is limited evidence to inform public health policy and resource allocation. METHODS: In a retrospective, matched cohort of Veterans and the Ontario general population between 1990-2019, we used routinely collected provincial administrative health data to examine chronic disease prevalence and health service use. Veterans were defined as former members of the Canadian Armed Forces or RCMP. Crude and adjusted effect estimates, and 95% confidence limits were calculated using logistic regression (asthma, COPD, diabetes, myocardial infarction, rheumatoid arthritis, family physician, specialist, emergency department, and home care visits, as well as hospitalizations). Modified Poisson was used to estimate relative differences in the prevalence of hypertension. Poisson regression compares rates of health services use between the two groups. RESULTS: The study included 30,576 Veterans and 122,293 matched civilians. In the first five years after transition to civilian life, Veterans were less likely than the general population to experience asthma (RR 0.50, 95% CI 0.48-0.53), COPD (RR 0.32, 95% CI 0.29-0.36), hypertension (RR 0.74, 95% CI 0.71-0.76), diabetes (RR 0.71, 95% CI 0.67-0.76), myocardial infarction (RR 0.76, 95% CI 0.63-0.92), and rheumatoid arthritis (RR 0.74, 95% CI 0.60-0.92). Compared to the general population, Veterans had greater odds of visiting a primary care physician (OR 1.76, 95% CI 1.70-1.83) or specialist physician (OR 1.39, 95% CI 1.35-1.42) at least once in the five-year period and lower odds of visiting the emergency department (OR 0.95, 95% CI 0.92-0.97). Risks of hospitalization and of receiving home care services were similar in both groups. CONCLUSIONS: Despite a lower burden of comorbidities, Veterans had slightly higher physician visit rates. While these visits may reflect an underlying need for services, our findings suggest that Canadian Veterans have good access to primary and specialty health care. But in light of contradictory findings in other jurisdictions, the underlying reasons for our findings warrant further study.

Self-reported auditory problems are associated with adverse mental health outcomes and alcohol misuse in the UK Armed Forces.

PURPOSE: Auditory problems, such as hearing loss and tinnitus, have been associated with mental health problems and alcohol misuse in the UK general population and in the US Armed Forces; however, few studies have examined these associations within the UK Armed Forces. The present study examined the association between auditory problems and probable common mental disorders, post-traumatic stress disorder and alcohol misuse. METHODS: 5474 serving and ex-service personnel from the UK Armed Forces were examined, selected from those who responded to phase two (data collection 2007-09) and phase three (2014-16) of a military cohort study. Multivariable logistic regression was used to examine the association between auditory problems at phase two and mental health problems at phase three. RESULTS: 9.7% of participants reported ever experiencing hearing problems alone, 7.9% reported tinnitus within the last month alone, and 7.8% reported hearing problems with tinnitus. After adjustment, hearing problems with tinnitus at phase two was associated with increased odds of probable common mental disorders (AOR = 1.50, 95% CI 1.09-2.08), post-traumatic stress disorder (AOR = 2.30, 95% CI 1.41-3.76), and alcohol misuse (AOR = 1.94, 95% CI 1.28-2.96) at phase three. Tinnitus alone was associated with probable post-traumatic stress disorder (AOR = 1.80, 95% CI 1.03-3.15); however, hearing problems alone were not associated with any outcomes of interest. CONCLUSIONS: The association between auditory problems and mental health problems emphasises the importance of the prevention of auditory problems in the Armed Forces: through enhanced audiometric screening, improved hearing protection equipment, and greater levels of utilisation of such equipment.

Validation of the mental health continuum: Short form among Canadian Armed Forces personnel.

Background: Compared to the general Canadian population, military members exhibit a higher prevalence of depressive disorders, anxiety disorders, and post-traumatic stress disorder. However, there is a paucity of research investigating the extent to which military members experience positive mental health. Validation of positive mental health measures, including the Mental Health Continuum - Short Form (MHC-SF), is necessary to determine whether well-being can be assessed in a valid and reliable manner among Canadian Armed Forces (CAF) military members. The purpose of this research was to assess the internal consistency reliability, convergent validity, factor structure, and measurement invariance of the MHC-SF among CAF Regular Force and Reserve Force military members. Data and methods: Data were drawn from the nationally representative 2013 Canadian Forces Mental Health Survey (CFMHS) conducted by Statistics Canada. A random sample of 8,200 CAF military personnel completed the CFMHS, representing 64,400 Regular Force and 4,460 Reserve Force CAF personnel. Results: As expected, all three MHC-SF subscales (psychological, social, and emotional well-being) correlated positively with life satisfaction, self-rated mental health, sense of belonging, and social support, and correlated negatively with psychological distress and disability due to health conditions. Internal consistency was high. Confirmatory factor analysis supported the three-factor structure of the MHC-SF, and measurement invariance was satisfied. Interpretation: Findings provided support for the reliability, convergent validity, factorial validity, and measurement invariance of the MHC-SF among both Regular Force and Reserve Force military samples. Therefore, researchers and clinicians can reliably implement the MHC-SF as a tool to assess, interpret, and predict military members' psychological, social, and emotional well-being.

Combat exposure and co-occurring mental health problems in UK Armed Forces personnel.

BACKGROUND: Mental disorders and alcohol misuse are often comorbid, and this comorbidity is more common in those who develop mental disorders following exposure to traumatic events. AIMS: To investigate the relationship between combat exposure and operational role (support versus combat) with mental disorders and associated comorbidity in a UK military cohort. METHODS: 4896 participants from a UK military cohort reported their operational role and frequency of exposure to combat events during deployment. Outcome measures included self-reported post-traumatic stress disorder, common mental disorder and alcohol misuse. RESULTS: Personnel reporting higher levels of combat exposure were more likely to meet criteria for two or more co-occurring mental disorders (odds ratio [OR] 3.90, 95% confidence interval [CI] 2.73-5.58). While having a combat role increased the risk of developing co-occurring disorders compared to having a support role (OR 1.67, 95% CI 1.26-2.23), this effect diminished following adjustment for variables including combat exposure (OR 0.89, 95% CI 0.62-1.27). CONCLUSIONS: Combat exposure may play a greater role in the development of comorbid mental disorders than operational role, i.e. job title. Clinicians treating military personnel should be alert to the increased risk of comorbid mental disorders and alcohol misuse among those with a history of combat exposure.

[Management of the COVID-19 epidemic in the carrier battle group (January-April 2020) by the Armed Forces Epidemiology and Public Health Center]. / Gestion de l'épidémie de COVID-19 au sein du groupe aéronaval (janvier­avril 2020) par le Centre d'épidémiologie et de santé publique des armées.

Objectives: Faced with the COVID-19 epidemic that occurred within the naval air group and the nuclear aircraft carrier Charles de Gaulle, the French Armed Forces Epidemiology and Public Health Center (CESPA) carried out an investigation (January - April 2020) whose objectives were: to identify the possible routes of introduction of the virus ; to describe the characteristics of the epidemic and to describe and model the dynamics of the epidemic's spread. Methods: A telephone survey was conducted. The biological diagnoses were transmitted by the medical antennas. A time/place/population analysis was carried out, as well as the description of the clinical pictures with their exposure factors. The instantaneous reproduction rate Rt of the epidemic was modeled. A spatial analysis of the epidemic on board was carried out. Forty-three viral genomes were sequenced and compared to the reference bases. Results: 0f 1767 sailors, 1568 (89%) participated in the telephone survey and 1064 (67.9%) were confirmed cases. Four patient profiles have been described: asymptomatic (13.0%); non-specific symptomatic (8.1%); specific symptomatic (76.3%); severe cases (2.6%). In univariate and multivariate analysis, age, overweight and obesity were significantly associated with the risk of having a severe form. Smoking was a protective factor. The evolution kinetics of Rt was in favor of an introduction of the virus at the end of February with a reintroduction during the stopover in Brest. Analysis of viral genomes ruled out introduction and spread of a single strain. Conclusion: Despite the control measures taken, an epidemic occurred. The often pauci-symptomatic clinical pictures resulted in a delay in identification. CESPA was able to carry out this epidemiological investigation within a highly constrained timeframe, showing all the interest of its integrated public health model.

Transcatheter aortic valve replacement in the developing world: Lessons learnt and its implications for practice.

Backrground: Transcatheter aortic valve replacement (TAVR) has become an accepted modality of treatment in intermediate and high surgical risk patients of symptomatic severe calcific aortic stenosis (AS). We herein report Indian data of 84 intermediate and high-risk patients who underwent TAVR at two Armed Forces cardiac centres. Methods: Most of the patients underwent TAVR in cardiac catheterization lab by percutaneous transfemoral approach, under conscious sedation. Patients were followed up and echocardiographic parameters were assessed after six months of procedure. Results: Total of 84 intermediate and high-risk patients underwent TAVR between Jan 2017 and June 2021. Mean age of population was 71.5 ± 8.4 years; 28.5% of patients had bicuspid aortic valve and Mean STS score was 6.34 ± 2.08. Majority (92.8%) patients underwent the procedure under conscious sedation. Self-expanding valves were used in 72.6% and balloon expandable in 27.4% of patients. Predilatation was done in 64% patients while 13% cases underwent post dilatation. Procedural mortality was 2.3%. Rate of permanent pacemaker implantation was 4.9%. Ischemic stroke occurred in 1.1% of patents. There was no case of severe paravalvular leak. Emergency surgical aortic valve replacement was done in 2.4% patients. Procedural success in this study was 97.6%. All-cause mortality was 9.5% at 6 months. Conclusions: TAVR is an effective treatment modality in intermediate and high-risk Indian patients with severe aortic stenosis. Patients with bicuspid or previous bio prosthetic aortic valves also have a good outcome post TAVR.

Sleep duration and physical performance during a 6-week military training course.

Sleep is vital in influencing effective training adaptations in the military. This study aimed to assess the relationship between sleep and changes in physical performance over 6 weeks of military training. A total of 22 officer-trainees (age: 24 ± 5 years) from the New Zealand Defence Force were used for this prospective cohort study. Participants wore wrist-actigraphs to monitor sleep, completed subjective wellbeing questionnaires weekly, and were tested for: 2.4-km run time-trial, maximum press-up and curl-ups before and after 6 weeks of training. Average sleep duration was calculated over 36 nights (6:10 ± 0:28 hr:min), and sleep duration at the mid-point (6:15 hr:min) was used to stratify the trainees into two quantile groups (UNDERS: 5:51 ± 0:29 hr:min, n = 11) and (OVERS: 6:27 ± 0:09 hr:min, n = 11). There were no significant group × time interactions for 2.4-km run, press-ups or curl-ups (p > .05); however, small effects were observed in favour of OVERS for 2.4-km run (59.8 versus 44.9 s; d = 0.26) and press-ups (4.7 versus 3.2 reps; d = 0.45). Subjective wellbeing scores resulted in a significant group × time interaction (p < .05), with large effect sizes in favour of the OVERS group for Fatigue in Week 1 (d = 0.90) and Week 3 (d = 0.87), and Soreness in Week 3 (d = 1.09) and Week 4 (d = 0.95). Sleeping more than 6:15 hr:min per night over 6 weeks was associated with small benefits to aspects of physical performance, and moderate to large benefits on subjective wellbeing measures when compared with sleeping < 6:15 hr:min.

Lifetime Prevalence and Comorbidity of Mental Disorders in the Two-wave 2002-2018 Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (CAFVMHS): Prévalence et Comorbidité de Durée de vie Des Troubles Mentaux Dans l'Enquête de Suivi Sur la Santé Mentale Auprès des Membres des Forces Armées Canadiennes et Des ex-Militaires (ESSMFACM) en Deux Cycles de 2002 à 2018.

OBJECTIVE: The current study used the Canadian Armed Forces Members and Veterans Mental Health Follow-up Survey (CAFVMHS) to (1) examine the incidence and prevalence of mental disorders and (2) estimate the comorbidity of mental disorders over the follow-up period. METHOD: The CAFVMHS (2018) is a longitudinal study with two time points of assessment. The sample is comprised of 2,941 Canadian Forces members and veterans who participated in the 2002 Canadian Community Health Survey: Canadian Forces Supplement. The World Health Organization Composite International Diagnostic Interview (WHO-CIDI) was utilized to diagnose Diagnostic and Statistical Manual-IV post-traumatic stress disorder (PTSD), major depressive episode (MDE), generalized anxiety disorder, social anxiety disorder (SAD), and alcohol abuse and dependence. Self-report health professional diagnoses were assessed for attention deficit hyperactivity disorder (ADHD), mania, obsessive compulsive disorder (OCD), and personality disorder. We established weighted prevalence of mental disorders and examined the association between mental disorders using logistic regression. RESULTS: In 2018, lifetime prevalence of any WHO-CIDI-based or self-reported mental disorder was 58.1%. Lifetime prevalence of any mood or anxiety disorder or PTSD was 54.0% in 2018. MDE (39.9%), SAD (25.7%), and PTSD (21.4%) were the most common mental disorders. There was a substantial increase in new onset or recurrence/persistence of mental disorders between the two measurement points (16-year assessment gap); 2002-2018 period prevalences were 43.5% for mood and anxiety disorder and 16.8% for alcohol abuse or dependence. The prevalence of self-reported ADHD, OCD, any personality disorder, and mania were 3.3%, 3.0%, 0.8%, and 0.8%, respectively. Comorbidity between mental disorders increased over the follow-up. CONCLUSIONS: This study demonstrates a high burden of mental disorders among a large Canadian military and veteran cohort. These findings underscore the importance of prevention and intervention strategies to reduce the burden of mental disorders and alcohol use disorders in these populations.
