The role of area deprivation index in health care disruptions among cancer survivors during the SARS-CoV-2 pandemic.

OBJECTIVE: To examine the associations between demographic/medical and geographic factors with follow-up medical care and health-related quality of life (HRQoL) among cancer survivors during the SARS-CoV-2 pandemic. STUDY DESIGN: Cross-sectional survey. METHODS: An online survey was sent to cancer survivors between May 2020 and January 2021, exploring their experience with SARS-CoV-2, follow-up care, and HRQoL. PolicyMap was used to geocode home addresses. Both geographic and demographic/medical factors were examined for their associations with SARS-CoV-2 experience, follow-up care, and HRQoL (FACT-G7). RESULTS: Geographic data were available for 9651 participants. Patients living in the highest area deprivation index (ADI) neighborhoods (most deprived) had higher odds of avoiding in-person general (odds ratio [OR] = 7.20; 95% confidence interval [CI] = 2.79-18.60), cancer (OR = 8.47; 95% CI = 3.73-19.30), and emergency (OR = 14.2; 95% CI = 5.57-36.30) medical care, as well as lower odds of using telemedicine (OR = 0.61; 95% CI = 0.52-0.73) compared to the lowest ADI group. Race/ethnicity was not associated with follow-up care after controlling for ADI. The effect of ADI on HRQoL was generally in the expected direction, with higher ADI being associated with worse HRQoL. CONCLUSIONS: ADI influenced follow-up medical care more than age, race/ethnicity, or health insurance type. Healthcare providers and institutions should focus on decreasing barriers to in-person and telemedicine health care that disproportionally impact those living in more deprived communities, which are exacerbated by health care disruptions like those caused by the SARS-CoV-2 pandemic.

Generalization of procedural motor sequence learning after a single practice trial.

When humans begin learning new motor skills, they typically display early rapid performance improvements. It is not well understood how knowledge acquired during this early skill learning period generalizes to new, related skills. Here, we addressed this question by investigating factors influencing generalization of early learning from a skill A to a different, but related skill B. Early skill generalization was tested over four experiments (N = 2095). Subjects successively learned two related motor sequence skills (skills A and B) over different practice schedules. Skill A and B sequences shared ordinal (i.e., matching keypress locations), transitional (i.e., ordered keypress pairs), parsing rule (i.e., distinct sequence events like repeated keypresses that can be used as a breakpoint for segmenting the sequence into smaller units) structures, or possessed no structure similarities. Results showed generalization for shared parsing rule structure between skills A and B after only a single 10-second practice trial of skill A. Manipulating the initial practice exposure to skill A (1 to 12 trials) and inter-practice rest interval (0-30 s) between skills A and B had no impact on parsing rule structure generalization. Furthermore, this generalization was not explained by stronger sensorimotor mapping between individual keypress actions and their symbolic representations. In contrast, learning from skill A did not generalize to skill B during early learning when the sequences shared only ordinal or transitional structure features. These results document sequence structure that can be very rapidly generalized during initial learning to facilitate generalization of skill.

Complete mesocolic excision versus standard resection for colon cancer: a systematic review and meta-analysis of perioperative safety and an evaluation of the use of a robotic approach.

PURPOSE: Complete mesocolic excision (CME) has been associated with improved oncological outcomes in treatment of colon cancer. However, widespread adoption is limited partly because of the technical complexity and perceived risks of the approach. The aim of out study was to evaluate the safety of CME compared to standard resection and to compare robotic versus laparoscopic approaches. METHODS: Two parallel searches were undertaken in MEDLINE, Embase and Web of Science databases 12 December 2021. The first was to evaluate IDEAL stage 3 evidence to compare complication rates as a surrogate marker of perioperative safety between CME and standard resection. The second independent search compared lymph node yield and survival outcomes between minimally invasive approaches. RESULTS: There were four randomized control trials (n = 1422) comparing CME to standard resection, and three studies comparing laparoscopic (n = 164) to robotic (n = 161) approaches. Compared to standard resection, CME was associated with a reduction in Clavien-Dindo grade 3 or higher complication rates (3.56% vs. 7.24%, p = 0.002), reduced blood loss (113.1 ml vs. 137.6 ml, p < 0.0001) and greater mean lymph node harvest (25.6 vs. 20.9 nodes, p = 0.001). Between the robotic and laparoscopic groups, there were no significant differences in complication rates, blood loss, lymph node yield, 5-year disease-free survival (OR 1.05, p = 0.87) and overall survival (OR 0.83, p = 0.54). CONCLUSIONS: Our study demonstrated improved safety with CME. There was no difference in safety or survival outcomes between robotic and laparoscopic CME. The advantage of a robotic approach may lie in the reduced learning curve and an increased penetration of minimally invasive approach to CME. Further studies are required to explore this.

Disordered Eating and Body Image Concerns in Young Adult Women With Scoliosis.

Background: Researchers have called for more investigation into disordered eating behaviors in females with scoliosis. Objective: The objective of the current study was to assess the associations between body image concerns, disease-specific indicators of scoliosis (ie, age of diagnosis, having undergone bracing treatment, being told by a physician your scoliosis required surgery, having a spinal fusion), quality of life, and disordered eating in a sample of young adult women diagnosed with idiopathic scoliosis during adolescence. Design: This study was cross-sectional in design. Methods: Participants were 177 young adult women ages 18 to 30 years diagnosed with idiopathic scoliosis by a physician who completed questionnaires online. Results: Undergoing bracing treatment (r = -.440; P < .001), greater age at scoliosis diagnosis (r = .563; P < .001), being told scoliosis required surgery (r = -.196; P < .050), annual income (r = .306; P < .001), level of education (r = .228; P < .010), and race/ethnicity (r = -.213; P < .050) were associated with the EDE-Q Global Score. The Body Shape Questionnaire Total Score and EDE-Q Global Score (r = .848; P < .001) and EDE-Q Weight Concern Score (r = .813; P < .001) were associated. The strongest correlations between the EDE-Q and the SRS-22-Revised Subscales were generally evidenced on the SRS-22-Revised Mental Health Subscale (rs ranged from -.200 to -.371; P < .001). After controlling for annual income, highest level of education, undergoing bracing treatment, and age of scoliosis diagnosis, the Body Shape Questionnaire Total Score was significantly correlated with the EDE-Q Eating Concern Score (standardized beta coefficient = .618; P < .001). Conclusions: These findings underscore the importance of assessing body image concerns in young adult women with scoliosis experiencing disordered eating as this information may provide valuable information relevant to treatment planning.

Abnormal brain function in photophobic patients with dry eye disease: An fMRI study.

BACKGROUND AND OBJECTIVES: Photophobia, a frequent and disabling symptom observed in various neurological conditions and eye diseases, is thought to involve maladaptive brain functioning. We assessed this hypothesis, using functional magnetic resonance imaging (fMRI) in photophobic patients with minimal-to-severe dry eye disease (DED), as compared to healthy controls. METHODS: This prospective, monocentric, comparative, cohort study included eleven photophobic DED patients compared to eight controls. Photophobic patients had a complete evaluation of DED to exclude any other cause of photophobia. All participants were scanned with fMRI under intermittent light stimulation with a LED lamp (27s. ON, 27 s. OFF), and cerebral activations were studied with univariate contrasts between the ON and OFF conditions, and with functional connectivity methods. RESULTS: Firstly, stimulation activated the occipital cortex more strongly in patients than in controls. Moreover, stimulation deactivated the superior temporal cortex in patients less than in controls. Secondly, functional connectivity analysis showed that light stimulation induced lesser decoupling between the occipital cortex and the salience and visual networks in patients than in controls. DISCUSSION: The current data shows that DED patients with photophobia have maladaptive brain anomalies. There is hyperactivity in the cortical visual system, associated with abnormal functional interactions, both within the visual cortex, and between visual areas and salience control mechanisms. Such anomalies show similarities with other conditions such as tinnitus, hyperacusis, and neuropathic pain. Those findings support novel neurally oriented methods for the care of patients with photophobia.

Emergence of a compositional neural code for written words: Recycling of a convolutional neural network for reading.

The visual word form area (VWFA) is a region of human inferotemporal cortex that emerges at a fixed location in the occipitotemporal cortex during reading acquisition and systematically responds to written words in literate individuals. According to the neuronal recycling hypothesis, this region arises through the repurposing, for letter recognition, of a subpart of the ventral visual pathway initially involved in face and object recognition. Furthermore, according to the biased connectivity hypothesis, its reproducible localization is due to preexisting connections from this subregion to areas involved in spoken-language processing. Here, we evaluate those hypotheses in an explicit computational model. We trained a deep convolutional neural network of the ventral visual pathway, first to categorize pictures and then to recognize written words invariantly for case, font, and size. We show that the model can account for many properties of the VWFA, particularly when a subset of units possesses a biased connectivity to word output units. The network develops a sparse, invariant representation of written words, based on a restricted set of reading-selective units. Their activation mimics several properties of the VWFA, and their lesioning causes a reading-specific deficit. The model predicts that, in literate brains, written words are encoded by a compositional neural code with neurons tuned either to individual letters and their ordinal position relative to word start or word ending or to pairs of letters (bigrams).

Utility of viscoelastography with TEG 6s to direct management of haemostasis during obstetric haemorrhage: a prospective observational study.

BACKGROUND: The TEG 6s is an automated cartridge-based device with limited description of use in obstetric haemorrhage. The aim of this analysis was to describe the utility of TEG 6s in identifying abnormal laboratory results of coagulation and platelet count, and inform an interventional treatment algorithm for postpartum haemorrhage. METHODS: A prospective observational cohort study of 521 women with moderate to severe obstetric haemorrhage (>1000 mL blood loss), including 372 women with at least one TEG 6s test. A non-pregnant control group was used for reference. TEG 6s test parameters Citrated Functional Fibrinogen (CFF), Citrated Kaolin TEG (CK) and Citrated Rapid TEG (CRT) were compared with paired laboratory tests of fibrinogen, PT/aPTT and platelet count, obtained during haemorrhage. RESULTS: Among 456 TEG 6s tests, 389 were matched with laboratory coagulation results. The receiver operator characteristic area-under-the-curve (95% CI) for CFF amplitude by 10 min to detect Clauss fibrinogen ≤2 g/L was 0.95 (0.91 to 0.99) (P<0.0001, sensitivity 0.74 and specificity 0.97 at ≤17 mm). False positives had median (IQR) Clauss fibrinogen of 2.4 (2.3-2.7) g/L. The CK-R time had some utility for detecting prolonged PT/aPTT, however a threshold for fresh frozen plasma transfusion was not established. A CRT maximum amplitude <57 mm, when CFF was ≥15 mm, identified four of eight samples with platelet count <75 × 109/L. CONCLUSION: The TEG 6s CFF can be used to identify low fibrinogen during obstetric haemorrhage. A value to identify transfusion thresholds for PT/aPTT and platelets was not established, and laboratory results should continue to be used.

Synaptic communication mediates the assembly of a self-organizing circuit that controls reproduction.

Migration of gonadotropin-releasing hormone (GnRH) neurons from their birthplace in the nasal placode to their hypothalamic destination is critical for vertebrate reproduction and species persistence. While their migration mode as individual GnRH neurons has been extensively studied, the role of GnRH-GnRH cell communication during migration remains largely unexplored. Here, we show in awake zebrafish larvae that migrating GnRH neurons pause at the nasal-forebrain junction and form clusters that act as interhemisphere neuronal ensembles. Within the ensembles, GnRH neurons create an isolated, spontaneously active circuit that is internally wired through monosynaptic glutamatergic synapses into which newborn GnRH neurons integrate before entering the brain. This initial phase of integration drives a phenotypic switch, which is essential for GnRH neurons to properly migrate toward their hypothalamic destination. Together, these experiments reveal a critical step for reproduction, which depends on synaptic communication between migrating GnRH neurons.

Sequential generation of linear cluster states from a single photon emitter.

Light states composed of multiple entangled photons-such as cluster states-are essential for developing and scaling-up quantum computing networks. Photonic cluster states can be obtained from single-photon sources and entangling gates, but so far this has only been done with probabilistic sources constrained to intrinsically low efficiencies, and an increasing hardware overhead. Here, we report the resource-efficient generation of polarization-encoded, individually-addressable photons in linear cluster states occupying a single spatial mode. We employ a single entangling-gate in a fiber loop configuration to sequentially entangle an ever-growing stream of photons originating from the currently most efficient single-photon source technology-a semiconductor quantum dot. With this apparatus, we demonstrate the generation of linear cluster states up to four photons in a single-mode fiber. The reported architecture can be programmed for linear-cluster states of any number of photons, that are required for photonic one-way quantum computing schemes.

The Patient-Centered Medical Home: Mental Health and Parenting Stress in Mothers of Children With Autism.

Objective: This study examined the correlations between receiving care in patient-centered medical home and maternal reports of their mental health and parenting stress in a national sample of mothers of children with autism spectrum disorder (ASD). Method: Participants were 1108 mothers of children with ASD (average age = 10.6 years; 81% male) from the 2011-2012 National Survey of Children's Health. Multiple linear regression analysis and polynomial logistic regression analysis were used to evaluate if having a child with ASD cared for in a patient-centered medical home was significantly associated with maternal reports of their parenting stress and mental health. We also assessed whether 5 indicators of the American Academy of Pediatrics medical home definition were differentially associated with maternal outcomes. Results: Receiving care in a patient-centered medical home was associated with maternal reports of less parenting stress (standardized ß = -0.201; P < .001) and better mental health (odds ratios range from 0.204 to 0.360; P < .001) after controlling for sociodemographic variables. Of the 5 indicators of the medical home definition, only effective care coordination was significantly associated with maternal perceptions of their parenting stress and mental health. Conclusion: Future longitudinal studies are needed to assess the temporal associations between patient-centered medical home status and maternal perceptions of their mental health and parenting stress in mothers of children with ASD.

Segmental Colectomy for Ulcerative Colitis: Is There a Place in Selected Patients Without Active Colitis? An International Multicentric Retrospective Study in 72 Patients.

BACKGROUND AND AIMS: The aim of this study was to report a multicentric experience of segmental colectomy [SC] in ulcerative colitis [UC] patients without active colitis, in order to assess if SC can or cannot represent an alternative to ileal pouch-anal anastomosis [IPAA]. METHODS: All UC patients undergoing SC were included. Postoperative complications according to ClavienDindo's classification, long term results, and risk factors for postoperative colitis and reoperation for colitis on the remnant colon, were assessed. RESULTS: A TOTAL OF: 72 UC patients underwent: sigmoidectomy [n = 28], right colectomy [n = 24], proctectomy [n = 11], or left colectomy [n = 9] for colonic cancer [n = 27], 'diverticulitis' [n = 17], colonic stenosis [n = 5], dysplasia or polyps [n = 8], and miscellaneous [n = 15]. Three patients died postoperatively and 5/69 patients [7%] developed early flare of UC within 3 months after SC. After a median followup of 40 months, 24/69 patients [35%] were reoperated after a median delay after SC of 19 months [range, 2-158 months]: 22/24 [92%] underwent total colectomy and ileorectal anastomosis [n = 9] or total coloproctectomy [TCP] [n = 13] and 2/24 [8%] an additional SC. Reasons for reoperation were: colitis [n = 14; 20%], cancer [n = 3] or dysplasia [n = 3], colonic stenosis [n = 1], and unknown reasons [n = 3]. Endoscopic score of colitis before SC was Mayo 23 in 5/5 [100%] patients with early flare vs 15/42 without early flare [36%; p = 0.0101] and in 9/12 [75%] patients with reoperation for colitis vs 11/35 without reoperation [31%; p = 0.016]. CONCLUSIONS: After segmental colectomy in UC patients, postoperative early colitis is rare [7%]. Segmental colectomy could possibly represent an alternative to IPAA in selected UC patients without active colitis.

Commentary: Challenges and Opportunities for Women in Dental Research.

This commentary integrates and expands on the preceding articles in this issue that document and celebrate a century of women's achievements in the International Association for Dental Research (IADR). The increasing participation and leadership of women in dental and craniofacial research and within the IADR were viewed from the perspective of a changing culture of science. The steps that have been taken by the IADR to develop greater inclusiveness are acknowledged, and some of the challenges that remain are discussed in terms of obstacles that are most often social or cultural in origin. Comparisons are made across countries, and the social determinants that lead to differences in women's participation are described. Recommendations are made for developing strategies to change elements of our institutional cultures that have provided advantages to some groups of researchers more than to others. The unconscious biases and a lack of commitment to diversity, equity, and inclusion that limit the participation of members of some groups limit the progress and achievements of science in general.

Gender Inequalities in the Dental Workforce: Global Perspectives.

The aim of this review is to investigate the growth of diversity and inclusion in global academic dental research with a focus on gender equality. A diverse range of research methodologies were used to conduct this review, including an extensive review of the literature, engagement of key informants in dental academic leadership positions around the world, and review of current data from a variety of national and international organizations. Results provide evidence of gender inequalities that currently persist in dental academics and research. Although the gender gap among graduating dental students in North America and the two most populous countries in Europe (the United Kingdom and France) has been narrowed, women make up 30% to 40% of registered dentists in countries throughout Europe, Oceania, Asia, and Africa. In academic dentistry around the globe, greater gender inequality was found to correlate with higher ranking academic and leadership positions in the United States, United Kingdom, several countries in European Union, Japan, and Saudi Arabia. Further disparities are noted in the dental research sector, where women make up 33% of dental researchers in the European Union, 35% in North America, 55% in Brazil, and 25% in Japan. Family and societal pressures, limited access to research funding, and lack of mentoring and leadership training opportunities are reported as also contributing to gender inequalities. To continue advancing gender equality in dental academia and research, efforts should be geared toward the collection and public dissemination of data on gender-specific distributions. Such evidence-driven information will guide the selection of future strategies and best practices for promoting gender equity in the dental workforce, which provides a major pipeline of researchers and scholars for the dental profession.

Repetitive antidotal treatment is crucial in eliminating eye pathology, respiratory toxicity and death following whole-body VX vapor exposure in freely moving rats.

Exposure to the chemical warfare nerve agent VX is extremely toxic, causing severe cholinergic symptoms. If not appropriately treated, death ultimately ensues. Based on our previously described whole-body vapor exposure system, we characterized in detail the clinical outcome, including respiratory dynamics, typical of whole-body exposure to lethal doses of VX vapor in freely moving rats. We further evaluated the efficacy of two different antidotal regimens, one comprising a single and the other repeated administration of antidotes, in countering the toxic effects of the exposure. We show that a 15 min exposure to air VX concentrations of 2.34-2.42 mg/m3 induced a late (15-30 min) onset of obvious cholinergic signs, which exacerbated over time, albeit without convulsions. Marked eye pathology was observed, characterized by pupil constriction to pinpoint, excessive lacrimation with red tears (chromodacryorrhea) and corneal damage. Respiratory distress was also evident, characterized by a three-fourfold increase in Penh values, an estimate of lung resistance, and by lung and diaphragm histological damage. A single administration of TAB (the oxime TMB-4, atropine and the anticholinergic and antiglutamatergic benactyzine) at the onset of clinical signs afforded only limited protection (66% survival), with clinical deterioration including weight loss, chromodacryorrhea, corneal damage, increased airway resistance and late death. In contrast, a combined therapy of TAB at the onset of clinical signs and repeated administration of atropine and toxogonin (ATOX) every 3-5 h, a maximum of five i.m. injections, led to 100% survival and a prompt recovery, accompanied by neither the above-described signs of eye pathology, nor by bronchoconstriction and respiratory distress. The necessity of recurrent treatments for successful elimination of VX vapor toxicity strongly supports continuous penetration of VX following termination of VX vapor exposure, most likely from a VX reservoir formed in the skin due to the exposure. This, combined with the above-described eye and respiratory pathology and absence of convulsions, are unique features of whole-body VX vapor exposure as compared to whole-body vapor exposure to other nerve agents, and should accordingly be considered when devising optimal countermeasures and medical protocols for treatment of VX vapor exposure.

To jump or not to jump - The Bereitschaftspotential required to jump into 192-meter abyss.

Self-initiated voluntary acts, such as pressing a button, are preceded by a surface-negative electrical brain potential, the Bereitschaftspotential (BP), that can be recorded over the human scalp using electroencephalography (EEG). While the BP's early component (BP1, generated in the supplementary and cingulate motor area) was linked to motivational, intentional and timing properties, the BP's late component (BP2, generated in the primary motor cortex) was found to be linked to motor execution and performance. Up to now, the BP required to initiate voluntary acts has only been recorded under well-controlled laboratory conditions, and it was unknown whether possible life-threatening decision making, e.g. required to jump into a 192-meter abyss, would impact this form of brain activity. Here we document for the first time pre-movement brain activity preceding 192-meter bungee jumping. We found that the BP's spatiotemporal dynamics reflected by BP1 and BP2 are comparable before 192-meter bungee jumping and jumping from 1-meter. These results, possible through recent advancements in wireless and portable EEG technology, suggest that possible life-threatening decision-making has no impact on the BP's spatiotemporal dynamics.

Parent-child agreement on the Behavior Rating Inventory of Executive Functioning (BRIEF) in a community sample of adolescents.

Despite its widespread use, a minimal amount is known regarding the agreement between parent and youth ratings of youth's executive functioning on the Behavior Rating Inventory of Executive Functioning (BRIEF) in typically developing youth. The present study examined parent-child agreement on the BRIEF with a community sample of adolescents and their parents. Ninety-seven parent-child dyads (Mage = 13.91 years; SD = .52) completed the BRIEF self- and parent-report forms and a demographic questionnaire. Intraclass Correlation Coefficients (ICCs) and paired sample t-tests were used to evaluate agreement between self- and parent-reports on the BRIEF. Total sample ICCs indicated moderate to good parent-child agreement (0.46-0.68). Parents from the total sample reported significantly higher mean T-scores for their adolescents on Inhibit, Working Memory, Planning/Organization, Behavioral Regulation Index (BRI), Metacognition Index, and Global Executive Composite. Differences were found in regard to gender and race/ethnicity: ICCs were higher between parent-girl dyads on the scales that comprise the BRI than between parent-boy dyads. Parent-adolescent ICCs were also higher for adolescents who self-identified as White in comparison to those who identified as Non-White/Mixed Race on Emotional Control. These findings suggest gender and racial/ethnic differences should be considered when examining parent-child agreement on the BRIEF in typically developing adolescents.

Mental health and parenting stress in mothers of children with diabetes treated in a patient-centred medical home.

BACKGROUND: Mothers of children with diabetes are at-risk for experiencing parenting stress and diminished mental/emotional health. To the best of our knowledge, no studies to date have examined whether there are differences in these outcomes between mothers whose diabetic child is managed in a patient-centred medical home or not. OBJECTIVE: The objective of the present study was to assess whether there were differences in mental health and parenting stress among mothers whose diabetic child was managed in a patient-centred medical home or not. METHODS: Two hundred fifty-three mothers of children with diabetes (mean age = 12.50 years; SD = 3.90) from the 2011-2012 National Survey of Children's Health were included in this study. Hierarchical multiple regression was conducted to determine the amount of variance that having a patient-centred medical home contributed to maternal emotional/mental health and parenting stress. RESULTS: After controlling for child sex, age, race/ethnicity and family poverty level, patient-centred medical home status was associated with better mental health for mothers and less parenting stress. Effective care coordination was the only subcomponent of the patient-centred medical home that significantly contributed to the variance in mother's mental/emotional health and parenting stress. CONCLUSIONS: Receiving care in a patient-centred medical home, particularly the care coordination component, may mitigate some of the negative maternal effects of managing a child's diabetes.

Exploratory Study of Low Resolution Electromagnetic Tomography (LORETA) Real-Time Z-Score Feedback in the Treatment of Pain in Patients with Head and Neck Cancer.

Acute pain from mucositis in patients with head and neck cancer (HNC) undergoing radiation therapy (RT) is common, and may not respond well to narcotics. We used low resolution electromagnetic tomography z-score neurofeedback (LFBz) to investigate whether patients could modify brain wave activity associated with acute pain and whether this would reduce the experience of pain. HNC patients scheduled for RT had baseline pre-pain onset measures (EEG and numeric rating scale) collected before RT and then at pain onset before using analgesics, after each LFBz session and at the end of RT. Up to six sessions of LFBz training were offered over the remaining RT. Up to six 20-min sessions of LFBz were offered over the remaining RT. Data were collected before and after each LFBz session and at the end of RT. Seventeen patients recruited; fourteen were treated and reported decreased pain perception. LFBz allowed patients to modify their brain activity in predesignated areas of the pain matrix toward the direction of their baseline, pre-pain condition (including Brodmann areas (BAs) 3, 4, 5, 13, 24, and 33). LFBz can modify brain regions relevant for pain and these changes were associated with self-reported decreases in pain perception.

Eating disorders in adolescent and young adult males: prevalence, diagnosis, and treatment strategies.

Males have largely been underrepresented in the eating disorder (ED) peer-reviewed literature. The current review paper examines prevalence rates, ED symptom presentation, and assessment and treatment strategies relevant to adolescent and young adult males. Adolescent and young adult males often report a greater desire to be bigger and more muscular compared to their female counterparts. Due to concerns that contemporary ED assessment tools are over reliant on items that evaluate stereotypically feminine indicators of ED pathology, male-specific ED measures, such as the Eating Disorder Assessment for Men, have been developed. Further validation work is necessary to establish the psychometric properties of these male-specific measures, particularly in adolescent male populations. Attention to a heightened prevalence of comorbid substance abuse disorders and the role that competitive sports play in perpetuating ED pathology are two factors that have been identified as important in the treatment of adolescent and young adult males with EDs.
