Shifting goalposts: widening discrepancies between girls' actual and ideal bodies predict disordered eating from preadolescence to adulthood.

BACKGROUND: Little is known regarding how disordered eating (DE) relates to perceived actual body size, ideal body size, and their discrepancy. This study examined changes in perceived actual body size, ideal body size, and actual-ideal discrepancies over time, and their relationship with subsequent DE. METHODS: Participants were 759 female twins from the Minnesota Twin Family Study who reported on body image and DE every three to five years between approximately ages 11 to 29. We used multilevel modeling to examine developmental trajectories of body mass index (BMI) and Body Rating Scale Actual, Ideal, and Actual-Ideal discrepancy scores and compared the degree to which BMI, BRS body size perceptions, and body dissatisfaction predicted DE behaviors and attitudes over time. Participants were treated as singletons in analyses. RESULTS: Perceived Actual body sizes and BMIs increased from age 10 to 33, whereas Ideal body sizes remained largely stable across time, resulting in growing Actual-Ideal discrepancies. Body size perceptions and Actual-Ideal discrepancies predicted subsequent DE behaviors and attitudes more strongly than did body dissatisfaction as measured by self-report questionnaires. CONCLUSIONS: This research advances understanding of how female body size perceptions and ideals change across development and highlights their relationship with subsequent DE.

Substance use disorders in hospice palliative care: A narrative review of challenges and a case for physician intervention.

OBJECTIVES: Substance use disorders (SUDs) are frequently encountered in hospice palliative care (HPC) and pose substantial quality-of-life issues for patients. However, most HPC physicians do not directly treat their patients' SUDs due to several institutional and personal barriers. This review will expand upon arguments for the integration of SUD treatment into HPC, will elucidate challenges for HPC providers, and will provide recommendations that address these challenges. METHODS: A thorough review of the literature was conducted. Arguments for the treatment of SUDs and recommendations for physicians have been synthesized and expanded upon. RESULTS: Treating SUD in HPC has the potential to improve adherence to care, access to social support, and outcomes for pain, mental health, and physical health. Barriers to SUD treatment in HPC include difficulties with accurate assessment, insufficient training, attitudes and stigma, and compromised pain management regimens. Recommendations for physicians and training environments to address these challenges include developing familiarity with standardized SUD assessment tools and pain management practice guidelines, creating and disseminating visual campaigns to combat stigma, including SUD assessment and intervention as fellowship competencies, and obtaining additional training in psychosocial interventions. SIGNIFICANCE OF RESULTS: By following these recommendations, HPC physicians can improve their competence and confidence in working with individuals with SUDs, which will help meet the pressing needs of this population.

Prospective Comparison Between Manual and Computer-Assisted (FOX) Cochlear Implant Fitting in Newly Implanted Patients.

OBJECTIVE: A prospective, longitudinal, randomized controlled trial with an original crossover design for 1 year was conducted to compare manual fitting to artificial intelligence-based fitting in newly implanted patients. DESIGN: Twenty-four patients who received their first cochlear implant (CI) were randomly assigned to the manual or Fitting to Outcome eXpert (FOX) arm; they followed the corresponding fitting procedures for 1 year. After 1 year, each patient was switched to another arm. The number of fittings, auditory outcomes (pure-tone thresholds, loudness scaling curves, spectral discrimination scores, bisyllabic word recognition in quiet and noise, and speech tracking), fitting session questionnaire, and CI parameters (T level, C level, Threshold Sound Pressure Level (T-SPL), Comfortable Sound Pressure Level (C-SPL), and loudness growth value) were compared between the two groups. Differences between the two groups were analyzed using the Mann-Whitney test, and Holm corrections were applied for multiple statistical tests. At the end of the crossover session, patients were offered the choice to continue with their old or new map. RESULTS: As early as 3 mo postactivation, the FOX group showed less variability and significantly better speech intelligibility in quiet conditions at 40 and 55 dB SPL and noise ( p < 0.05) with median phoneme scores of 50%, 70%, and 50% at 55, 70, and 85 dB SPL compared with 45%, 50%, and 40%, respectively. This group showed better results at 12 mo postactivation ( p < 0.05). In the manual group, 100% of the patients decided to keep the new FOX map, and 82% performed better with the FOX map. In the FOX group, 63% of the patients decided to keep the manual map, although the measurable outcome had not improved. In this group, participants reported to prefer the manual map because it felt more comfortable, even if the FOX map gave better measured outcome. CONCLUSION: Although the study size remains relatively small, the AI-FOX approach was equivalent to or even outperformed the manual approach in hearing performance, comfort, and resources. Furthermore, FOX is a tool capable of continuous improvement by comparing its predictions with observed results and is continuously learning from clinicians' practice, which is why this technology promises major advances in the future.

One size does not fit all: Trajectories of body image development and their predictors in early adolescence.

Background: Negative body image predicts many adverse outcomes. The current study prospectively examined patterns of body esteem development in early adolescence and identified predictors of developmental subtypes. Methods: 328 girls and 429 boys reported annually across a 4-year period (Mage at baseline = 11.14, SD = 0.35) on body esteem, appearance ideal internalization, perceived sociocultural pressures, appearance comparisons, appearance-related teasing, self-esteem, positive and negative affect, and dietary restraint. We performed latent class growth analyses to identify the most common trajectories of body esteem development and examine risk and protective factors for body image development. Results: Three developmental subgroups were identified: (a) high body esteem (39.1%); (b) moderate body esteem (46.1%); and (c) low body esteem (14.8%). Body esteem was stable within the low trajectory and there were minor fluctuations in the high and moderate trajectories. Greater appearance-related teasing, lower self-esteem, less positive affect, and higher dietary restraint predicted the low trajectory, whereas higher self-esteem and lower dietary restraint best predicted the high trajectory. Conclusions: Low body esteem appears to be largely stable from age 11 years. Prevention programming may be enhanced by incorporating components to address transdiagnostic resilience factors such as self-esteem and positive affect.

Using photovoice to increase social inclusion of people with disabilities: Reflections on the benefits and challenges.

The aim of this study was to understand the mobility experiences of mobility device users regarding the environmental and social barriers and facilitators in their community and to discuss the benefits and challenges of using photovoice, as a participatory methodology, to increase social participation for people with disabilities. Photovoice was used with mobility device users (n = 70) in two different locations in Canada. The participants took pictures for two weeks and then participated in individual interviews and focus group sessions to discuss their photographs. The participants took over 1,000 pictures that were grouped into five themes around social participation and accessibility. They chose the most illustrative pictures to share in an exhibit to create a dialogue with different stakeholders. Using photovoice offered many benefits such as allowing the participants to be equal partners of the research and made their voices heard, but also presented disability and study-related challenges.

Prevalence of social, cognitive, and emotional impairment among individuals with food addiction.

PURPOSE: The clinical utility of the construct of food addiction has been heavily debated. Though food addiction has been associated with psychosocial impairment in clinical samples, it is critical to examine these associations in non-clinical samples, to obtain unbiased evidence regarding this phenomenon's clinical significance. It is also unknown which types of impairment are most common in food addiction. This observational study explored the association of self-reported food addiction with impairment in the domains of social, cognitive, and emotional functioning. METHODS: Participants (356 university students and 544 adults recruited through Mechanical Turk) completed the Yale Food Addiction Scale 2.0 and Clinical Impairment Assessment 3.0 questionnaire, as well as measures of emotional eating, reward-driven eating, binge eating, and general disordered eating. RESULTS: Food addiction scores showed large correlations with emotional (r = 0.55, 0.57), social (r = 0.56, 0.59), and cognitive impairment (r = 0.58, 0.53) in the student and Mechanical Turk samples, respectively. The most common difficulties endorsed were emotional (e.g., feeling ashamed or critical of oneself, upset, or worried due to one's eating habits), followed by social and cognitive. CONCLUSION: Food addiction was strongly associated with psychosocial impairment in two non-clinical samples, suggesting this phenomenon merits further investigation. We found substantial associations of food addiction with emotional as well as social and cognitive impairment.

The Visuo-Spatial Abilities Diagnosis (VSAD) test: Evaluating the potential cognitive difficulties of children with vestibular impairment through a new tablet-based computerized test battery.

Recent data collected on adult patients with vestibular loss (VL) tend to demonstrate possible cognitive impairments in visuospatial working memory, mental rotation, selective attention, and space orientation. However, the neuropsychological profile of children with VL remains largely under-investigated in the scientific literature. Although previous research has shown that children with VL may experience some degree of delayed motor development, it is not yet clear if VL could also lead to specific delayed cognitive development. In this study, we will present the development and validation of a new tablet-based computerized test battery (VSAD) that evaluates visuospatial working memory, mental rotation, selective attention, and space orientation abilities. Thirteen children with VL and 54 average-age matched healthy children performed the VSAD and classical paper-and-pencil neuropsychological tasks twice within a 1-month interval. Our results demonstrated a good concurrent validity with strong correlations between the visuospatial working memory, mental rotation, and space orientation tests of the VSAD and classical tasks. Test-retest reliability was also supported through good intra-class coefficients. However, the test of selective attention showed no concurrent validity with the matched classical task. The discriminant validity of the VSAD was partially supported for visuospatial working memory and mental rotation performance accuracy. The VSAD shows good concurrent validity and reliability for measuring visuospatial working memory, mental rotation, and space orientation in children with VL. Future studies are needed to extend discriminant validity with other populations.

Conceptualizing addictive-like eating: A qualitative analysis.

Debates regarding addictive-like eating have generated several conceptualizations of this construct. Qualitative research helps ensure that conceptualizations capture how individuals may experience addictive-like eating. In this study, we conducted semi-structured interviews with ten participants who identified themselves as addicted to food, or to food and eating, to determine how they conceptualized their addictive-like eating. Using thematic analysis, we identified four themes: (1) Social Environment, describing how past and present social environments affected addictive-like eating; (2) Situational Cues, encompassing situational contributions to addictive-like eating; (3) Persistent Cognitions, including preoccupation with food and loss of control; and (4) Impact of Weight, encompassing weight gain and its perceived impact on health, body image, and distress. Participants described properties specific to their preferred foods, as well as environmental and cognitive factors contributing to addictive-like eating. These descriptions were not completely captured by either the substance-based "food addiction" or behavioural "eating addiction" frameworks, though characteristics consistent with both were present. Further, existing scales of addictive-like eating do not assess the impact of social and situational cues, suggesting a need for new or revised measures. We propose a working definition of addictive-like eating that incorporates the characteristics described.

"There is no way to avoid the first bite": A qualitative investigation of addictive-like eating in treatment-seeking Brazilian women and men.

There has been polarizing debate on addictive-like eating in recent years. To move toward valid definition and measurement of this construct, qualitative research describing individuals' experiences is needed. The present study explored how Brazilian men and women define and experience addictive-like eating. Interviews were conducted with 7 men and 8 women (Mage = 46.6 years, MBMI = 35.43 kg/m2) seeking treatment for addictive-like eating. Thematic analysis of interviews identified three saturated, overarching themes describing participants' conceptualizations of the (1) characteristics, (2) causal factors, and (3) consequences of addictive-like eating. Lack of control was a key characteristic of addictive-like eating described by all participants. A causal factor which most participants described was emotional eating. Consequences included emotional, interpersonal, occupational, and health-related impairments which appeared primarily related to weight gain, rather than to the pattern of addictive-like eating itself. These results are largely consistent with those of previous qualitative studies. Importantly, the symptoms described by our participants and in previous qualitative studies may be inadequately captured by existing self-report questionnaires designed to assess addictive-like eating. To address this potential limitation, we provide recommendations for assessing the full range of possible addictive-like eating symptoms.

The need to consume: Hoarding as a shared psychological feature of compulsive buying and binge eating.

INTRODUCTION: Compulsive buying and binge eating are two frequently co-occurring psychiatric conditions. Hoarding, which is the psychological need to excessively gather and store items, is frequently associated with both compulsive buying severity and binge eating severity. In the present study, we explored whether different dimensions of hoarding are a shared feature of compulsive buying and binge eating. METHOD: Participants consisted of 434 people seeking treatment for compulsive buying disorder. Registered psychiatrists confirmed the diagnosis of compulsive buying through semi-structured clinical interviews. Participants also completed measures to assess compulsive buying severity, binge eating severity, and dimensions of hoarding (acquisition, difficulty discarding, and clutter). Two-hundred and seven participants completed all three measures. RESULTS: Significant correlations were found between compulsive buying severity and the acquisition dimension of hoarding. Binge eating severity was significantly correlated with all three dimensions of hoarding. Hierarchical regression analysis found that compulsive buying severity was a significant predictor of binge eating severity. However, compulsive buying severity no longer predicted binge eating severity when the dimensions of hoarding were included simultaneously in the model. Clutter was the only subscale of hoarding to predict binge eating severity in step two of the regression analysis. CONCLUSION: Our results suggest that the psychological need to excessively gather and store items may constitute a shared process that is important in understanding behaviors characterized by excessive consumption such as compulsive buying and binge eating.

Moving beyond the "eating addiction" versus "food addiction" debate: Comment on Schulte et al. (2017).

In a recent commentary, Schulte et al. (2017) argued that addictive-like eating should be conceptualized as a substance use disorder rather than a behavioural addiction, and noted that many parallels that Hebebrand et al. (2014) drew between addictive-like eating and behavioural addictions apply likewise to substance use disorders. However, we argue that many of the arguments advanced by Schulte et al. (2017) in support of a substance-based food addiction model, including the important role played by ingested substances, are nonspecific. That is, these arguments apply equally well to behavioural addictions and other mental disorders, notably eating disorders, which raises the question of whether the phenomenon of addictive-like eating is encompassed by existing eating disorder diagnoses. Similarities between addictive-like eating and substance use, no matter how compelling, do not ensure the validity or clinical utility of a substance-based food addiction model and should not drive the conceptualization of addictive-like eating. The present commentary discusses problems with Schulte et al.'s (2017) arguments for substance-based food addiction, and draws attention to alternative conceptualizations of addictive-like eating which risk being overlooked when this conversation is framed as a dichotomous debate between the food and eating addiction models.

The development of a new questionnaire for cognitive complaints in vertigo: the Neuropsychological Vertigo Inventory (NVI).

Vertigo patients frequently complain of emotional and associated cognitive problems, yet currently, there is no satisfactory questionnaire to measure these associated problems. In the present paper, we propose a new internet-based Neuropsychological Vertigo Inventory (NVI; French) that evaluates attention, memory, emotion, space perception, time perception, vision, and motor abilities. The questionnaire was created using four steps: (1) open interviews with patients suffering from vertigo; (2) semi-structured interviews with an analysis grid to quantify and define the various cognitive and emotional problems reported by the patients; (3) a first version of an internet questionnaire tested on 108 vertigo participants; and (4) the selection of subscale items using principal component analyses (PCA). From the development phase, the revised NVI was composed of seven subscales, each with four items (28 items). In the validation phase, Cronbach's alphas were performed on the revised NVI for total and each subscale score, and to test extreme groups validity, the analyses of covariance (ANCOVAs) taking into account age were performed between 108 vertigo and 104 non-vertigo participants. The Cronbach's alphas showed good to satisfactory coefficients for the total and for all subscale scores, demonstrating acceptable reliability. The extreme groups validity analyses (ANCOVAs) were reliable for the total scale and for four subscales. Supplementary analyses showed no effect of hearing difficulties and an inverse age effect for attention and emotion subscales, with reduced problems with increased age in the vertigo participants. The NVI provides a useful new questionnaire to determine cognitive and emotional neuropsychological complaints that are associated with vertigo.

Nutritional considerations for gender-diverse people: a qualitative mini review.

Dietitians working with gender-diverse people may require different skills and knowledge than those caring for cisgender men and women, as indicated by a growing body of literature that highlights gender-diverse people's unique experiences with and relationships to nutrition and eating behaviors. To provide insight into how dietitians can best serve this population, this mini review identifies and summarizes qualitative studies that investigate gender-diverse people's lived experiences and perspectives regarding nutrition, eating disorders, and access to eating-related healthcare services. Fourteen studies examining nutrition or eating behaviors among gender-diverse samples were selected through a systematic search and screening process: 11 focused on disordered eating or eating disorders and the remaining three focused on nutritional needs, nutritional knowledge, and food insecurity. Extracted themes included: using dietary restriction to suppress secondary sex characteristics or conform to societal norms; the impact of gender-affirming care on disordered eating; negative experiences with, and beliefs about, nutrition and eating disorders healthcare services; and suggestions for clinicians. Recommendations discuss the need for increased trans literacy among clinicians, the creation of safe spaces for gender-diverse people with eating disorders, and the importance of dual competencies in eating disorders treatment and gender-affirming care.

Effect of a CI Programming Fitting Tool with Artificial Intelligence in Experienced Cochlear Implant Patients.

OBJECTIVE: Cochlear implants (CIs) are the treatment of choice for patients with severe to profound hearing loss. The hearing results, however, considerably vary across patients. This may partly be due to variability in the CI fitting. We investigated the effect of FOX, a software tool to program CIs using artificial intelligence (AI), on hearing outcomes. METHODS: Forty-seven experienced CI patients who came to our tertiary CI center for their annual follow-up between 2017 and 2020 were recruited for this study. They received a new CI map created by the AI software tool. CI parameters and auditory outcomes obtained with this new map were compared with those of the initial manual map after 15 days of take-home experience. Within-patient differences were assessed. At the end of the study, the patients were offered a choice to continue using the AI map or to revert to their old manual map. RESULTS: Several auditory outcomes improved with the AI map, namely, pure tone audiometric threshold at 6,000 Hz (median improvement 10 dB, range = -20 to 50 dB, Z = -2.608, p = 0.008), phonemic discrimination scores (median improvement 10%, range = 0% to 30%, Z = -4.061, p = 0.001), and soft-intensity (median improvement of 10%, range = -20% to 90%, Z = -4.412, p < 0.001) to normal-intensity (median improvement of 10%, range = -30% to 60%, Z = -3.35, p < 0.001) speech audiometric scores. CONCLUSION: The AI-assisted CI mapping model as a potential assistive tool may improve audiological outcomes for experienced CI patients, including high-frequency pure tone audiometry and audiometric speech scores at low and normal presentation levels.Clinical trial registration: NCT03700268.

Integrated treatment for comorbid eating disorders and substance use disorders: a scoping review protocol.

OBJECTIVE: This review will identify and summarize the literature on the integrated treatment of comorbid eating disorders and substance use disorders, focusing on clinical practice guidelines and treatment studies. INTRODUCTION: Eating disorders and substance use disorders are the deadliest psychiatric conditions, frequently co-occur, and are linked to greater symptom severity and poorer treatment outcomes. Despite repeated calls for their integrated treatment, such an approach has rarely been empirically evaluated. To advance the development of integrated treatments for comorbid eating disorders and substance use disorders, a critical first step is to describe existing treatment guidelines and summarize research evidence for this approach. INCLUSION CRITERIA: This review will consider all peer-reviewed and gray literature describing the integrated treatment of comorbid eating disorders and substance use disorders, focusing on i) clinical practice guidelines; and ii) treatment studies. We will not place limitations on populations, types of eating disorders, types of substance use disorders, or other contextual factors. METHODS: Databases to be searched will include MEDLINE (Ovid), Embase, CINAHL (EBSCOhost), PsycINFO (EBSCOhost), Scopus, and clinical practice guidelines databases identified by CADTH Grey Matters. No date or language limits will be applied to the search. At the screening stage, we will only consider literature in English or French. Two independent reviewers will screen studies at the title/abstract and full-text levels, and extract relevant studies. Disagreements will be resolved through discussion. Findings will be presented in tabular format and a narrative summary. REVIEW REGISTRATION: Open Science Framework https://osf.io/za35j/.

Normative body image development: A longitudinal meta-analysis of mean-level change.

This meta-analysis synthesized longitudinal data on mean-level change in body image, focusing on the constructs of body satisfaction and dissatisfaction, body esteem, perceived attractiveness, valuation, self-objectification, and body shame. We searched five databases and accessed unpublished data to identify studies that assessed body image at two or more time points over six months or longer. Analyses were based on data from 142 samples representing a total of 128,254 participants. The age associated with the midpoint of measurement intervals ranged from 6 to 54 years. Multilevel metaregression models examined standardized yearly mean change, and the potential moderators of body image construct, gender, birth cohort, attrition rate, age, and time lag. Boys and men showed fluctuations in overall body image with net-improvements between ages 10 and 24. Girls and women showed worsening body image between ages 10 and 16, but improvements between ages 16 and 24. Change was greatest between ages 10 and 14, and stabilized around age 24. We found no effect of construct, birth cohort, or attrition rate. Results suggest a need to revise understandings of normative body image development: sensitive periods may occur somewhat earlier than previously believed, and body image may show mean-level improvements during certain age ranges.

A State-of-the-Art Review on the Use of Modafinil as A Performance-enhancing Drug in the Context of Military Operationality.

INTRODUCTION: Modafinil is an eugeroic drug that has been examined to maintain or recover wakefulness, alertness, and cognitive performance when sleep deprived. In a nonmilitary context, the use of modafinil as a nootropic or smart drug, i.e., to improve cognitive performance without being sleep deprived, increases. Although cognitive performance is receiving more explicit attention in a military context, research into the impact of modafinil as a smart drug in function of operationality is lacking. Therefore, the current review aimed at presenting a current state-of-the-art and research agenda on modafinil as a smart drug. Beside the question whether modafinil has an effect or not on cognitive performance, we examined four research questions based on the knowledge on modafinil in sleep-deprived subjects: (1) Is there a difference between the effect of modafinil as a smart drug when administered in repeated doses versus one single dose?; (2) Is the effect of modafinil as a smart drug dose-dependent?; (3) Are there individual-related and/or task-related impact factors?; and (4) What are the reported mental and/or somatic side effects of modafinil as a smart drug? METHOD: We conducted a systematic search of the literature in the databases PubMed, Web of Science, and Scopus, using the search terms "Modafinil" and "Cognitive enhance*" in combination with specific terms related to the research questions. The inclusion criteria were studies on healthy human subjects with quantifiable cognitive outcome based on cognitive tasks. RESULTS: We found no literature on the impact of a repeated intake of modafinil as a smart drug, although, in users, intake occurs on a regular basis. Moreover, although modafinil was initially said to comprise no risk for abuse, there are now indications that modafinil works on the same neurobiological mechanisms as other addictive stimulants. There is also no thorough research into a potential risk for overconfidence, whereas this risk was identified in sleep-deprived subjects. Furthermore, eventual enhancing effects were beneficial only in persons with an initial lower performance level and/or performing more difficult tasks and modafinil has an adverse effect when used under time pressure and may negatively impact physical performance. Finally, time-on-task may interact with the dose taken. DISCUSSION: The use of modafinil as a smart drug should be examined in function of different military profiles considering their individual performance level and the task characteristics in terms of cognitive demands, physical demands, and sleep availability. It is not yet clear to what extent an improvement in one component (e.g., cognitive performance) may negatively affect another component (e.g., physical performance). Moreover, potential risks for abuse and overconfidence in both regular and occasional intake should be thoroughly investigated to depict the trade-off between user benefits and unwanted side effects. We identified that there is a current risk to the field, as this trade-off has been deemed acceptable for sleep-deprived subjects (considering the risk of sleep deprivation to performance) but this reasoning cannot and should not be readily transposed to non-sleep-deprived individuals. We thus conclude against the use of modafinil as a cognitive enhancer in military contexts that do not involve sleep deprivation.

Prioritization of patients access to outpatient augmentative and alternative communication services in Quebec: a decision tool.

PURPOSE: A large number of people living with a chronic disability wait a long time to access publicly funded rehabilitation services such as Augmentative and Alternative Communication (AAC) services, and there is no standardized tool to prioritize these patients. We aimed to develop a prioritization tool to improve the organization and access to the care for this population. METHODS: In this sequential mixed methods study, we began with a qualitative phase in which we conducted semi-structured interviews with 14 stakeholders including patients, their caregivers, and AAC service providers in Quebec City, Canada to gather their ideas about prioritization criteria. Then, during a half-day consensus group meeting with stakeholders, using a consensus-seeking technique (i.e. Technique for Research of Information by Animation of a Group of Experts), we reached consensus on the most important prioritization criteria. These criteria informed the quantitative phase in which used an electronic questionnaire to collect stakeholders' views regarding the relative weights for each of the selected criteria. We analyzed these data using a hybrid quantitative method called group based fuzzy analytical hierarchy process, to obtain the importance weights of the selected eight criteria. RESULTS: Analyses of the interviews revealed 48 criteria. Collectively, the stakeholders reached consensus on eight criteria, and through the electronic questionnaire they defined the selected criteria's importance weights. The selected eight prioritization criteria and their importance weights are: person's safety (weight: 0.274), risks development potential (weight: 0.144), psychological well-being (weight: 0.140), physical well-being (weight: 0.124), life prognosis (weight: 0.106), possible impact on social environment (weight: 0.085), interpersonal relationships (weight: 0.073), and responsibilities and social role (weight: 0.054). CONCLUSION: In this study, we co-developed a prioritization decision tool with the key stakeholders for prioritization of patients who are referred to AAC services in rehabilitation settings.IMPLICATIONS FOR REHABILIATIONStudies in Canada have shown that people in Canada with a need for rehabilitation services are not receiving publicly available services in a timely manner.There is no standardized tool for the prioritization of AAC patients.In this mixed methods study, we co-developed a prioritization tool with key stakeholders for prioritization of patients who are referred to AAC services in a rehabilitation center in Quebec, Canada.

Adult Female Sleep During Hypoxic Bed Rest.

Purpose: Hypobaric hypoxic habitats are currently being touted as a potential solution to minimise decompression procedures in preparation for extra vehicular activities during future space missions. Since astronauts will live in hypoxic environments for the duration of such missions, the present study sought to elucidate the separate and combined effects of inactivity [simulated with the experimental bed rest (BR) model] and hypoxia on sleep characteristics in women. Methods: Twelve women (Age = 27 ± 3 year) took part in three 10-day interventions, in a repeated measures cross-over counterbalanced design: (1) normobaric normoxic BR (NBR), (2) normobaric hypoxic BR (HBR; simulated altitude of 4,000 m), and (3) normobaric hypoxic ambulatory (HAMB; 4,000 m) confinement, during which sleep was assessed on night 1 and night 10 with polysomnography. In addition, one baseline sleep assessment was performed. This baseline assessment, although lacking a confinement aspect, was included statistically as a fourth comparison (i.e., pseudo normobaric normoxic ambulatory; pNAMB) in the present study. Results: Hypoxia decreased sleep efficiency (p = 0.019), increased N1% sleep (p = 0.030), decreased N3 sleep duration (p = 0.003), and increased apnea hypopnea index (p < 0.001). BR impaired sleep maintenance, efficiency, and architecture [e.g., N2% sleep increased (p = 0.033)]. Specifically, for N3% sleep, the effects of partial pressure of oxygen and activity interacted. Hypoxia decreased N3% sleep both when active (pNAMB vs HAMB; p < 0.001) and inactive (NBR vs HBR; p = 0.021), however, this decrease was attenuated in the inactive state (-3.8%) compared to the active state (-10.2%). Conclusion: A 10-day exposure to hypoxia and BR negatively impacted sleep on multiple levels as in macrostructure, microstructure and respiratory functioning. Interestingly, hypoxia appeared to have less adverse effects on sleep macrostructure while the participants were inactive (bed ridden) compared to when ambulatory. Data were missing to some extent (i.e., 20.8%). Therefore, multiple imputation was used, and our results should be considered as exploratory.

Lessons From Special Forces Operators for Elite Team Sports Training: How to Make the Whole Greater Than the Sum of the Parts.

This methodology paper describes the design of a holistic and multidisciplinary human performance program within the Belgian Special Forces Group, the Tier 1 Special Operations unit of the Belgian Defense. Performance management approaches in the military draw heavily on sports science. The key component of the program design described here is its integrative nature, which team sports training might benefit from. The basic rationale behind the program was to bridge several gaps: the gap between physical and mental training; the gap between the curative or preventive medical approach and the performance enhancement approach; and the gap between individual and team training. To achieve this goal, the methodology of Intervention Mapping was applied, and a multidisciplinary team of training and care professionals was constituted with operational stakeholders. This was the first step in the program design. The second step took a year, and consisted of formal and informal consultations, participant observations and task analyses. These two first stages and their conclusions are described in the Method section. The Results section covers the next two stages (three and four) of the process, which aimed at defining the content of the program; and to test a pilot project implementation. The third stage encompassed the choice of the most relevant assessment and intervention tools for the target population, within each area of expertise. This is described extensively, to allow for replication. The fourth and last stage was to "test drive" the real-life integration and implementation of the whole program at the scale of a single team (8 individuals). For obvious confidentiality reasons, the content data will not be reported extensively here. Implications for wider-scale implementation and tie-back to sports team training are presented.
