Review
Active-duty military personnel are subjected to sustained periods of energy deficit during combat and training, leaving them susceptible to detrimental reductions in body weight. The importance of adequate dietary protein intake during periods of intense physical training is well established, where previous research has primarily focused on muscle protein synthesis, muscle recovery, and physical performance. Research on how protein intake may influence body weight regulation in this population is lacking; therefore, the objective of this review was to evaluate the role of dietary protein in body weight regulation among active-duty military during an energy deficit. A literature search based on fixed inclusion and exclusion criteria was performed. English language peer-reviewed journal articles from inception to 3 June 2023 were selected for extraction and quality assessment. Eight studies were identified with outcomes described narratively. The study duration ranged from eight days to six months. Protein was directly provided to participants in all studies except for one. Three studies supplied additional protein via supplementation. The Downs and Black Checklist was used to assess study quality. Five studies were classified as good, two as fair, and one as excellent. All studies reported mean weight loss following energy deficit: the most severe was 4.0 kg. Protein dose during energy deficit varied from 0.5 g/kg/day to 2.4 g/kg/day. Six studies reported mean reductions in fat mass, with the largest being 4.5 kg. Four studies reported mean reductions in fat-free mass, while two studies reported an increase. Results support the recommendation that greater than 0.8 g/kg/day is necessary to mitigate the impact of energy deficit on a decline in lean body mass, while intakes up to 1.6 g/kg/day may be preferred. However, exact recommendations cannot be inferred as the severity and duration of energy deficit varied across studies. Longer and larger investigations are needed to elucidate protein's role during energy deficit in active-duty military.

INTRODUCTION
Military service personnel are required to deploy to austere environments where they are exposed to harsh conditions. Many service personnel continue to wear contact lenses when deployed as they are an effective alternative to spectacles by affording superior ergonomic functionality, although they are associated with significant complications. We aimed to explore the prevalence and type of contact lens-related complications among deployed service personnel worldwide.
METHODS
A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 statement. PubMed, Medline, CINAHL and EMBASE databases were searched for relevant articles published between 1950 and 2023. The keywords 'contact lens' and 'military' or 'army' or 'navy' or 'air force' and 'austere' or 'deployed' or 'adverse' were used.
RESULTS
Five eligible articles were included. Excluded articles reported contact lens wear in the firm base, were not related to military personnel or did not involve the deployed setting. Major complications associated with contact lens wear included microbial keratitis and contact lens-related discomfort. Excluding case reports, the overall incidence of contact lens-related complications ranged from 0.35% to 25.4%. The three case reports included in this systematic review described keratitis, keratitis and contact lens-related discomfort as significant complications. These case reports also detailed time to initial presentation and type of contact lens worn when complications were encountered. Types of deployed conditions service personnel were exposed to included desert, temperate and underwater environments.
CONCLUSIONS
We highlight a scarcity of recent data regarding contact lens-related complications in the deployed setting. While contact lens-wearing service personnel are at risk of infectious keratitis and contact lens-related discomfort, we recommend good-quality data collection on contact lens wearing schedules and complication rates to steer guidance on contact lens wear in service personnel.

INTRODUCTION
A third of Canadian Armed Forces veterans report difficulty adjusting to post-military life. Moreover, an estimated 40% of Canadian veterans live with chronic pain, which is likely associated with greater needs during the transition from military to civilian life. This review explores challenges and transition needs among military personnel living with chronic pain as they return to civilian life.
METHODS
We searched MEDLINE, EMBASE, CINAHL, Scopus, and Web of Science from inception to July 2022, for qualitative, observational, and mixed-method studies exploring transition needs among military veterans released with chronic pain. Reviewers, working independently and in duplicate, conducted screening and used a standardized and pilot-tested data collection form to extract data from all included studies. Content analysis was used to create a coding template to identify patterns in challenges and unmet needs of veterans transitioning to civilian life, and we summarized our findings in a descriptive manner.
RESULTS
Of 10,532 unique citations, we identified 43 studies that reported transition challenges and needs of military personnel; however, none were specific to individuals released with chronic pain. Most studies (41 of 43; 95%) focused on military personnel in general, with one study enrolling individuals with traumatic brain injury and another including homeless veterans. We identified military-to-civilian challenges in seven areas: (1) identity, (2) interpersonal interactions/relationships, (3) employment, (4) education, (5) finances, (6) self-care and mental health, and (7) accessing services and care.
CONCLUSIONS
Military personnel who transition to civilian life report several important challenges; however, the generalizability to individuals released with chronic pain is uncertain. Further research is needed to better understand the transition experiences of veterans with chronic pain to best address their needs and enhance their well-being.

Review
Poor sleep quality is prevalent among members of the military but rates of poor sleep quality vary between studies. This study examined the global prevalence of poor sleep quality in military personnel and veterans as well as possible moderators of prevalence differences between studies. PubMed, EMBASE, Web of Science, and PsycINFO were systematically searched from their inception dates to September 1, 2022. Studies were included if they were conducted on military personnel and/or veterans and prevalence estimates of poor sleep quality could be generated from assessments with standardized tools. A random-effects model was used to calculate the pooled prevalence and its 95% confidence intervals (CIs). Fifty-nine studies (N = 28,100) were included for analysis with sample sizes ranging from 14 to 8481. Two studies were rated as "high quality" (3.39%), while 57 were rated as "moderate quality" (96.61%). The overall pooled prevalence of poor sleep quality in military personnel and veterans was 69.00% (95% CI: 62.33-75.30%); pooled rates were 57.79% (95% CI: 49.88-65.50%) and 82.88% (95% CI: 74.08-90.21%) for active duty personnel and veterans, respectively. Subgroup analyses indicated study region, study design, sampling method, Pittsburg Sleep Quality Index cut-off values, and service type moderated prevalence of poor sleep quality. Meta-regression analyses indicated sample size, mean age, depression and posttraumatic stress disorder (PTSD) were associated with prevalence differences between studies. Poor sleep quality was more common in both active duty military personnel and veterans who were older and those who reported PTSD or depression. Regular monitoring of sleep quality and sleep hygiene should be promoted in this population. More relevant studies in middle- and low-income countries should also be conducted.

INTRODUCTION
There continues to be a growing demand for military-civilian partnerships (MCPs) in research collaborations developing medical trauma care in domestic and international affairs. The objective of this comprehensive review is to investigate the difference in the quantity of MCP trauma and critical care publications before and after the COVID-19 pandemic.
METHODS
A systematic literature review was performed for the calendar years 2018 and 2021 utilizing MEDLINE, Cochrane, and EMBASE databases. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we performed a three-tiered review of 603 English language articles to identify trauma-related military and/or civilian partners and describe the changes in geographical relationships.
RESULTS
A total of 96 (2018) and 119 (2021) articles met screening criteria for trauma and critical care studies and were used for final data extraction. Ultimately, 59 (2018) and 71 (2021) papers met the inclusion criteria of identifying trauma/critical care MCPs and identified both military and civilian partners. There was also an increase from 10 (2018) to 17 (2021) publications that mentioned advocacy for MCP. Using the author affiliations, four regional MCP types were recorded: of 2018 articles, locoregional (3.4%), US-national (47.5%), single international country (42.4%), and between multiple countries (6.8%); of 2021 articles, locoregional (15.5%), US-national (38%), single international country (29.6%), and between multiple countries (16.9%). There has been an increase in the number of locoregional and multinational MCPs and an overall increase in the number of collaborative trauma publications and MCP advocacy papers. A national geographical heat map was developed to illustrate the changes from 2018 to 2021.
CONCLUSIONS
There has been an increase in the number of recorded trauma and critical care MCP publications post-pandemic. The growth in the number of manuscripts in more regions post-pandemic suggests an increase in the recognition of collaborations that contribute not only to conflict readiness but also advancements in trauma and surgical care.

The increasing number of suicides among military populations cannot be fully accounted for by conventional risk factors like Post-Traumatic Stress Disorder (PTSD). As a result, researchers and theorists propose that delving into the concept of Moral Injury could offer a more comprehensive understanding of the phenomenon of suicide. Moral Injury is not currently a recognized mental health disorder but can be associated with PTSD. Moral Injury is a multi-dimensional issue that profoundly affects emotional, psychological, behavioral, social, and spiritual well-being. The objective of this systematic review is to examine the association between Moral Injury and suicidal behavior (suicide ideation, plans and or suicide attempt) within military populations. The review will specifically concentrate on identifying and analyzing studies that have investigated the connection between these variables, with a specific focus on the context of military personnel both serving and former serving members. Of the 2214 articles identified as part of this review, 12 studies satisfied the research criteria with a total participant sample having an average age of 40.7 years. The male population accounted for 78.6% of the overall sample. Two studies were identified as high-quality, while the remaining ten were rated as moderate. The analysis of these twelve studies consistently affirms a connection between Moral Injury and suicidal behavior; most obviously, that exposure to morally injurious events substantially amplify the risk of suicide, with higher levels of potential exposure being linked to increased Moral Injury and heightened levels of suicidal behavior. Our review uncovered noteworthy findings regarding the association between Moral Injury and suicidal behavior, marking a pioneering effort in exploring this association and offering valuable insights into this emerging issue. Several limitations are noted regarding this review and recommendations are made concerning the need to prioritize, expand and employ longitudinal research designs that include non-military populations such as first responders (e.g., police, paramedics, firefighters) and medical, nursing, or allied health professionals-all disciplines known to be impacted by Moral Injury.

BACKGROUND
There is an increased risk of subsequent concussion and musculoskeletal injury upon return to play following a sports-related concussion. Whilst there are numerous assessments available for clinicians for diagnosis and during return to play following concussion, many may lack the ability to detect these subclinical changes in function. Currently, there is no consensus or collated sources on the reliability, validity and feasibility of these assessments, which makes it difficult for clinicians and practitioners to select the most appropriate assessment for their needs.
OBJECTIVES
This systematic review aims to (1) consolidate the reliability and validity of motor function assessments across the time course of concussion management and (2) summarise their feasibility for clinicians and other end-users.
METHODS
A systematic search of five databases was conducted. Eligible studies were: (1) original research; (2) full-text English language; (3) peer-reviewed with level III evidence or higher; (4) assessed the validity of lower-limb motor assessments used to diagnose or determine readiness for athletes or military personnel who had sustained a concussion or; (5) assessed the test-retest reliability of lower-limb motor assessments used for concussion management amongst healthy athletes. Acceptable lower-limb motor assessments were dichotomised into instrumented and non-instrumented and then classified into static (stable around a fixed point), dynamic (movement around a fixed point), gait, and other categories. Each study was assessed using the COSMIN checklist to establish methodological and measurement quality.
RESULTS
A total of 1270 records were identified, with 637 duplicates removed. Titles and abstracts of 633 records were analysed, with 158 being retained for full-text review. A total of 67 records were included in this review; 37 records assessed reliability, and 35 records assessed the validity of lower-limb motor assessments. There were 42 different assessments included in the review, with 43% being non-instrumented, subjective assessments. Consistent evidence supported the use of instrumented assessments over non-instrumented, with gait-based assessments demonstrating sufficient reliability and validity compared to static or dynamic assessments.
CONCLUSION
These findings suggest that instrumented, gait-based assessments should be prioritised over static or dynamic balance assessments. The use of laboratory equipment (i.e. 3D motion capture, pressure sensitive walkways) on average exhibited sufficient reliability and validity, yet demonstrate poor feasibility. Further high-quality studies evaluating the reliability and validity of more readily available devices (i.e. inertial measurement units) are needed to fill the gap in current concussion management protocols. Practitioners can use this resource to understand the accuracy and precision of the assessments they have at their disposal to make informed decisions regarding the management of concussion.

Journal of Orthopaedics Sep 2023Femoral neck stress fractures are rare fractures traditionally found in athletes and military personnel. There is limited literature on return to activity. (Review)
Review
BACKGROUND
Femoral neck stress fractures are rare fractures traditionally found in athletes and military personnel. There is limited literature on return to activity.
OBJECTIVES
To report return to activity rates and times, and long-term outcomes for femoral neck stress fractures reported in the literature. To examine the effects of bone metabolic dysfunction and surgical management on return to activity following FNSF.
RESEARCH DESIGN & METHODS
A systematic literature review of case reports and case series on adults with femoral neck stress fracture that were diagnosed by gross fracture line on X-ray or gold-standard diagnosis with MRI was conducted. Initial search was limited to articles published from January 1997 to Jan 2023 listed in Medline, Embase, and Scopus. Additional articles were manually added via search of retained paper sources. Patient demographics, fracture type, return to activity time, and surgical vs non-surgical treatment modality were collected. In addition, long-term outcomes and metabolic effects, if reported, were abstracted.
RESULTS
A total of 40 case reports or case series were retained. 123 stress fractures of the femoral neck from 103 patients were compiled. Of the 103 patients, data on return to activity at least one year following treatment was available for 53 patients. 71% (37/53) of those with long-term follow-up information returned to full pre-injury activity. 24% (13/53) at long-term follow-up had functional recovery but did not return to pre-injury activity due to residual pain. 4% (3/53) had disabling pain. Metabolic workup information was available for 36 patients.
CONCLUSION
Long-term follow-up and return to activity information following FNSF treatment are not commonly reported. Based on the available data, outcomes appear benign with most returning to full activity. There is a clear need for standardization of follow-up periods and hip function measure after FNSF treatment. Additionally, a sizable proportion of FNSF occurred in a new population of low-activity individuals with abnormal bone metabolism, which warrants further exploration.

Review
INTRODUCTION
Targeted Muscle Reinnervation (TMR) is a surgical technique utilized to alleviate post-amputation neuroma pain, reduce reliance on narcotic pain medication, and enhance control of prosthetic devices. Motor targets for upper extremity TMR vary depending on injury patterns and amputation levels, with conventional transfer patterns serving as general guides. This study aims to summarize the common patterns of TMR in transradial and transhumeral amputations, focusing on anatomic and surgical considerations.
METHODS
A comprehensive systematic review of TMR literature was conducted by two independent physician reviewers (M.H.A. and D.M.G.R.) to identify the prevailing motor targets, while considering injury patterns and amputation levels.
INCLUSION CRITERIA
1) TMR techniques, outcomes, or advancements; 2) Original research, systematic reviews, meta-analyses, or clinical trials; 3) Peer-reviewed journal articles or reputable conference proceedings.
EXCLUSION CRITERIA
non-English resources, editorials, opinion pieces, and case reports. The databases utilized include MEDLINE (PubMed), EMBASE (Scopus) and Cochrane CENTRAL, last searched 01APR2023.
RESULTS
The reviewed literature revealed multiple motor targets described for upper extremity TMR out of our included 51 studies. However, the selection of motor targets is influenced by the availability of viable options based on injury patterns and amputation levels. Conventional transfer patterns provide useful guidance for determining appropriate motor targets in transradial and transhumeral amputations.
DISCUSSION
TMR has played a significant role in military medicine, particularly in addressing the impact of blast-related injuries. The energy associated with such injuries often results in substantial soft tissue defects, higher amputation levels, and increased post-amputation pain. TMR, in conjunction with advancements in prosthetic technology and ongoing military research, offers improved outcomes to help achieve the goals of active-duty service members. The capabilities and applications of TMR continue to expand rapidly due to its high surgical success rate, technological innovations in prosthetic care, and favorable patient outcomes. As technology evolves to include implantable devices, osseointegration techniques, and bidirectional neuroprosthetic devices, the future of amputation surgery and TMR holds immense promise, offering innovative solutions to optimize patient outcomes. It is important to note, this review was limited to the data available in the included resources which was mostly qualitative; thus, it did not involve primary data analysis.

Meta-Analysis Review
AIM
The aim of this study was to identify the influencing factors of sleep disorders and sleep quality in healthcare workers during the COVID-19 pandemic.
DESIGN
Systematic review and meta-analysis of observational research.
METHODS
The databases of the Cochrane Library, Web of Science, PubMed, Embase, SinoMed database, CNKI, Wanfang Data, and VIP were systematically searched. The quality of studies was assessed using the Agency for Healthcare Research and Quality evaluation criteria and the Newcastle-Ottawa scale.
RESULTS
A total of 29 studies were included, of which 20 were cross-sectional studies, eight were cohort studies, and 1 was a case-control study; 17 influencing factors were finally identified. Greater risk of sleep disturbance was associated with female gender, single relationship status, chronic disease, insomnia history, less exercise, lack of social support, frontline work, days served in frontline work, department of service, night shift, years of work experience, anxiety, depression, stress, received psychological assistance, worried about being infected, and degree of fear with COVID-19.
CONCLUSIONS
During the COVID-19 pandemic, healthcare workers did have worse sleep quality than the general population. The influencing factors of sleep disorders and sleep quality in healthcare workers are multifaceted. Identification and timely intervention of resolvable influencing factors are particularly important for preventing sleep disorders and improving sleep.
