Energy Trade-off and 4 Extreme Human Body Types.

Resource trade-off theory suggests that increased performance on a given trait comes at the cost of decreased performance on other traits. Growth data from 1889 subjects (996 girls) were used from the GrowUp1974 Gothenburg study. Energy Trade-Off (ETO) between height and weight for individuals with extreme body types was characterized using a novel ETO-Score (ETOS). Four extreme body types were defined based on height and ETOI at early adulthood: tall-slender, short-stout, short-slender, and tall-stout; their growth trajectories assessed from ages 0.5-17.5 years.A GWAS using UK BioBank data was conducted to identify gene variants associated with height, BMI, and for the first time with ETOS. Height and ETOS trajectories show a two-hit pattern with profound changes during early infancy and at puberty for tall-slender and short-stout body types. Several loci (including FTO, ADCY3, GDF5, ) and pathways were identified by GWAS as being highly associated with ETOS. The most strongly associated pathways were related to "extracellular matrix," "signal transduction," "chromatin organization," and "energy metabolism." ETOS represents a novel anthropometric trait with utility in describing body types. We discovered the multiple genomic loci and pathways probably involved in energy trade-off.

Apixaban and Rivaroxaban Anti-Xa Concentration Utilization in Clinical Practice

Drug-specific anti-Xa concentrations can be used to assess the presence of drug effects; however, there is inadequate guidance for clinicians on the interpretation and clinical application of these results. The purpose of this study is to review patients' first apixaban and rivaroxaban anti-Xa concentrations to identify indications for monitoring and common therapeutic interventions made based on the results. In addition, we compared bleeding and thrombotic outcomes between the obesity group body mass index ≥40 kg/m 2 and the standard group body mass index 25-39.9 kg/m 2 . A retrospective analysis was conducted at a large academic medical center from January 1, 2020, to December 31, 2020. Primary outcomes were indications for anti-Xa concentrations and interventions on results. A total of 180 patients were included in the analysis, with 119 patients (66%) in the apixaban group and 61 patients (34%) in the rivaroxaban group. The most common indications for anti-Xa concentrations were extreme body weight (23%) and concern for bleeding (22%). About half of the anti-Xa concentrations resulted in therapy changes including holding for procedure, switching to heparin or enoxaparin, holding for an elevated anti-Xa concentration or concern for bleeding, adjusting direct-acting oral anticoagulant dose, or switching to an alternative oral anticoagulant. There were no differences in bleeding complications (5% [2] vs. 16% [14], P = 0.11) or thrombotic complications (8% [3] vs. 9% [8], P = 0.85) between the obesity group and the standard group. Despite the lack of validation of therapeutic ranges for anti-Xa concentrations, this study showed clinical situations where anti-Xa concentration monitoring can be of value.

Selective sweeps on different pigmentation genes mediate convergent evolution of island melanism in two incipient bird species.

Insular organisms often evolve predictable phenotypes, like flightlessness, extreme body sizes, or increased melanin deposition. The evolutionary forces and molecular targets mediating these patterns remain mostly unknown. Here we study the Chestnut-bellied Monarch (Monarcha castaneiventris) from the Solomon Islands, a complex of closely related subspecies in the early stages of speciation. On the large island of Makira M. c. megarhynchus has a chestnut belly, whereas on the small satellite islands of Ugi, and Santa Ana and Santa Catalina (SA/SC) M. c. ugiensis is entirely iridescent blue-black (i.e., melanic). Melanism has likely evolved twice, as the Ugi and SA/SC populations were established independently. To investigate the genetic basis of melanism on each island we generated whole genome sequence data from all three populations. Non-synonymous mutations at the MC1R pigmentation gene are associated with melanism on SA/SC, while ASIP, an antagonistic ligand of MC1R, is associated with melanism on Ugi. Both genes show evidence of selective sweeps in traditional summary statistics and statistics derived from the ancestral recombination graph (ARG). Using the ARG in combination with machine learning, we inferred selection strength, timing of onset and allele frequency trajectories. MC1R shows evidence of a recent, strong, soft selective sweep. The region including ASIP shows more complex signatures; however, we find evidence for sweeps in mutations near ASIP, which are comparatively older than those on MC1R and have been under relatively strong selection. Overall, our study shows convergent melanism results from selective sweeps at independent molecular targets, evolving in taxa where coloration likely mediates reproductive isolation with the neighboring chestnut-bellied subspecies.

‘Half Man, Half Chair’: Disability and the Posthuman Technological Imaginaries of Miserrimus Dexter's Sensational Body in Wilkie Collins'The Law and the Lady(1875)

Questions of identity are central to Wilkie Collins’ 1875 novel, The Law and the Lady, where we find the extraordinary and androgynous body of wheelchair-using Miserrimus Dexter. Disabled and without legs since birth, and described as ‘the new Centaur, half-man, half-chair,’ Dexter’s disfigured body is one of Collins’ most shocking and confusing characters. As a fusion of man and machinery, Dexter is even more extreme than Collins’ many other sensational characters and fascinating because of his exaggerated physical difference, eccentric behaviour, and hybrid identity. Dexter is represented as a hybrid, a bizarre mix of the human, non-human animal, and machine. He is a unique example of Collins’ sensational ability to draw on social fears and anxieties by creating an extreme body that is capable of crossing ‘natural’ boundaries, propelling Dexter towards what we now know as ‘posthumanism.’ This essay examines how the sensation genre allows Collins to test out freakish/posthuman/cyborg bodies. Dexter’s physical limitations are overcome by uniting his body with technology. However, as his identity becomes completely bound up with the mechanism he uses to move about, Collins depicts him becoming less human and increasingly unhinged. Collins’ novel expresses anxieties about the dehumanising impact of the rise of technology rather than enthusiasm for the transhuman possibilities offered.

혈류제한 운동이 휠체어 컬링 선수의 신체조성 및 근력에 미치는 영향

The purpose of this study was to examine the effects of 4 weeks of delivery technique exercise with blood flower restriction(BFR) on upper extremity body composition and muscle strength and the effect of passive lower extremity muscle exercise with BFR band on lower extremity body composition of wheelchair curling players with spinal cord injury.BR Six wheelchair curling players were collected. Body composition and muscle strength extremities were measured pre and post exercise. BFR exercise program was progressed 3 times/week for 4 weeks. The data was analysed by Wilcoxon signed-rank test. Body composition was not significantly different on upper and lower extremities. In the muscle strength, total work(J) in 60 deg/sec on left elbow flexion were significantly decreased, but wrist flexion were significantly improved both left and right (p.05).BR In conclusion, the delivery technique exercise with BFR was found to help improve the forearm strength of wheelchair curlers. The delivery technique exercise with BFR is recommended as an auxiliary exercise to improve the performance of wheelchair curlers.

Risk and Management of Bleeding Complications with Direct Oral Anticoagulants in Patients with Atrial Fibrillation and Venous Thromboembolism: a Narrative Review.

Atrial fibrillation (AF) and venous thromboembolism (VTE) are highly prevalent conditions with a significant healthcare burden, and represent the main indications for anticoagulation. Direct oral anticoagulants (DOACs) are the first choice treatment of AF/VTE, and have become the most prescribed class of anticoagulants globally, overtaking vitamin K antagonists (VKAs). Compared to VKAs, DOACs have a similar or better efficacy/safety profile, with reduced risk of intracerebral hemorrhage (ICH), while the risk of major bleeding and other bleeding harms may vary depending on the type of DOAC. We have critically reviewed available evidence from randomized controlled trials and observational studies regarding the risk of bleeding complications of DOACs compared to VKAs in patients with AF and VTE. Special patient populations (e.g., elderly, extreme body weights, chronic kidney disease) have specifically been addressed. Management of bleeding complications and possible resumption of anticoagulation, in particular after ICH and gastrointestinal bleeding, are also discussed. Finally, some suggestions are provided to choose the optimal DOAC to minimize adverse events according to individual patient characteristics and bleeding risk.

ESTIMATION OF PERSONAL DOSE EQUIVALENT HP(0.07) USING CASO4:DY TEFLON DISC-BASED EXTREMITY DOSEMETER.

The radiation workers in India use extremity dosemeter in occupational areas where there is likelihood of receiving significant dose to extremities of the body. Algorithm used for the estimation of whole body dose and extremity dose of wrist are same and is based on slab phantom calibration. However, internationally, different phantoms are recommended for calibration of dosemeter used for extremity and whole body. The recommended quantity for estimation of dose to extremity is the personal dose equivalent Hp(0.07) at 0.07mm depth. In light of this, an algorithm was developed for estimation of wrist dose in terms of Hp(0.07) based on calibration performed on ISO recommended pillar phantom. Performance of the dosemeter for the estimation of Hp(0.07) with new algorithm was carried out at different angular exposures of photon beams and mixed field of photon and beta. Comparison of results obtained for two types of ISO phantoms (slab and pillar) is also performed for photon beams to highlight the uncertainty caused due to the use of the slab phantom. In case of beta radiation, it was found that the size and shape of the phantom has very little influence in the response of the dosemeter. Performance of the dosemeter using ISO slab and ISO pillar phantoms for beta radiation using the prevalent algorithm was carried out and found to be within the uncertainty limits laid down by ISO except at angle 60°.

PENYULUHAN PROGRAM PENGUATAN OTOT EKSTREMITAS BAWAH PADA BURUH PABRIK BATIK NUR HASIDA

Batik is one of the works and cultural heritage of Indonesia which is a combination of art and technology by the ancestors of the Indonesian nation. Batik has various types and various ways of making such as written, stamped, dyed, and many more. With so many existing batik-making processes, the scope of human movement is certainly very broad. This can cause various complaints, especially in the lower extremity body because the position of the body when working is not in an ergonomic position. In this case, of course, the role of physiotherapy is needed to provide direction and solutions to complaints that occur. This is what happened to the batik craftsmen of Nur Hasida who felt a complaint in the form of achy pain in the lower extremities of the body. Therefore, several exercises were carried out such as warming-up (sprinting in place and jumping jacks), strengthening (squats, split squats, side leg raises and reverse lunges), and stretching (quad stretches, inner thigh stretches, and toe extensions). to strengthen the muscles of the lower extremities as well as education about ergonomic positions while working.

Pathway-specific GABAergic inhibition contributes to the gain of resilience against anorexia-like behavior of adolescent female mice.

Anorexia nervosa is one of the most debilitating mental illnesses that emerges during adolescence, especially among females. Anorexia nervosa is characterized by severe voluntary food restriction and compulsive exercising, which combine to cause extreme body weight loss. We use activity-based anorexia (ABA), an animal model, to investigate the neurobiological bases of vulnerability to anorexia nervosa. This is a Mini-Review, focused on new ideas that have emerged based on recent findings from the Aoki Lab. Our findings point to the cellular and molecular underpinnings of three ABA phenomena: (1) age-dependence of ABA vulnerability; (2) individual differences in the persistence of ABA vulnerability during adolescence; (3) GABAergic synaptic plasticity in the hippocampus and the prefrontal cortex that contributes to the suppression of the maladaptive anorexia-like behaviors. We also include new data on the contribution to ABA vulnerability by cell type-specific knockdown of a GABA receptor subunit, α4, in dorsal hippocampus. Although the GABA system recurs as a key player in the gain of ABA resilience, the data predict why targeting the GABA system, singularly, may have only limited efficacy in treating anorexia nervosa. This is because boosting the GABAergic system may suppress the maladaptive behavior of over-exercising but could also suppress food consumption. We hypothesize that a sub-anesthetic dose of ketamine may be the magic bullet, since a single injection of this drug to mid-adolescent female mice undergoing ABA induction enhances food consumption and reduces wheel running, thereby reducing body weight loss through plasticity at excitatory synaptic inputs to both excitatory and inhibitory neurons. The same treatment is not as efficacious during late adolescence but multiple dosing of ketamine can suppress ABA vulnerability partially. This caveat underscores the importance of conducting behavioral, synaptic and molecular analyses across multiple time points spanning the developmental stage of adolescence and into adulthood. Since this is a Mini-Review, we recommend additional literature for readers seeking more comprehensive reviews on these subjects.

Psychic reality articulation in nonmainstream body modifications: A single‐case study

AbstractNonmainstream body modifications appear as a social and psychological phenomenon that has been explored from many angles: as identity construction, self‐ownership vindication or masking of mental distress. The purpose of this research is to approach this issue, implicating psychic reality constitution and the peculiar way a subject performing these modifications links the three registers of reality according to Lacan: the Real, the Symbolic and the Imaginary. A qualitative research on a single case was carried out, based on in‐depth interviews. The participant has performed multiple extreme body modifications within a transformation project he calls: “alien cyborg”. They include, tattoos, mutilations, and suspensions, among others. The interviews delivered several themes related to the three main categories corresponding to the Lacanian registers. The themes reveal the way the subject lives the body's jouissances and how he deals with them standing on each register. The body project as nomination of an unrepresentable inconsistency of the body and pain control, “normalcy” and “perfectionism” as main signifiers sustaining the whole chain, and a reshaping of the body image that can be sustained by the Other's gaze. The project raises as a means of building a specific connection with reality and projecting his body in a space where there seems to be no limitations.

Muscle Strength and Balance as Mediators in the Association between Physical Activity and Health-Related Quality of Life in Community-Dwelling Older Adults

Lower extremity muscle strength (LEMS) and body balance (BB) are essential for older adults to maintain an upright posture and autonomously perform their basic activities of daily living. This study aimed to examine whether LEMS and BB mediate the relationship between physical activity (PA) and health-related quality of life (HRQoL) in a large sample of community-dwelling older adults. This is a cross-sectional study carried out with 802 individuals, 401 males and 401 females (69.8 ± 5.6 years), residents of the Autonomous Region of Madeira, Portugal. PA and HRQoL were assessed by the Baecke Questionnaire and e SF-36, respectively. LEMS was assessed by the Senior Fitness Test and BB by the Fullerton Advance Balance (FAB). The serial mediation pathway model pointed out that LEMS and BB partially mediated the association between PA and HRQoL in approximately 39.6% and 47%, respectively. The total variance in HRQoL explained by the entire model was 98%. Our findings may indicate the role that LEMS and BB play in the relationship between PA and HRQoL in the older population.

A Cohort Study of the Surgical Risks and Prediction of Complications in Surgical Tracheostomies.

Current protocols favor percutaneous tracheostomies over open procedures. We analyzed the effects of this conversion from the open approach to the percutaneous procedure in terms of relevant clinical status, complications, and mortality in surgical open tracheostomies. Relevant laboratory and clinical parameters, potentially associated with complications, were also examined. Comparison of clinical, laboratory data and outcome of surgical tracheostomy during the two eras. Investigate potential pertinent predictive parameters associated with complications. A single center retrospective case series of consecutive patients who underwent surgical tracheostomy between the years 2006-2009 ("early era") and 2016-2020 ("late era"). The study included 304 patients, 160 in the "early" and 144 in the "late" era. Despite a 78% increase in patient volume in the intensive care units, there was a 55% decrease in surgical tracheostomy during the "late era". Significantly more patients with structural deformities (p < 0.001), insulin dependent diabetes mellitus (p = 0.004), extreme (high and low) body weight (p = 0.006), anemia (p < 0.001) and coagulation disorders (p < 0.001), were referred for an open tracheostomy during the "late era". The complication rate was significantly higher during the "late era" (11.7 vs. 2.5%, OR 6.09 CI 95% [1.91-19.39], p = 0.001). Diabetes mellitus (p = 0.005), anemia (p = 0.033), malnutrition (p = 0.017), thrombocytopenia (p = 0.002) and poor renal function, (p = 0.008), were all significantly associated with higher complication rates. Risk assessment and training programs must reflect the decrease in surgical volume of open tracheostomies and consequently reduced experience. The increase of a patient subset characterized by pertinent comorbidities should reflect this change.

There is no relationship between lower extremity muscle strength and cognitive function with static balance. There is a relationship between lower extremity muscle strength and cognitive function with dynamic balance.

Effect of Long-term Exercise Training on Physical Performance and Cardiorespiratory Function in Adults With CKD: A Randomized Controlled Trial

The safety and efficacy of long-term exercise training in reducing physical functional loss in older adults with advanced CKD and comorbidity is uncertain. Multicenter, parallel group, randomized controlled trial. Adults 55 years and older with estimated glomerular filtration rate (eGFR) of 15 to<45 mL/min/1.73 m2 enrolled from centers in Baltimore and Boston. Twelve months of in-center supervised exercise training incorporating majority aerobic but also muscle strengthening activities or a group health education control intervention, randomly assigned in 1:1 ratio. Primary outcomes were cardiorespiratory fitness and submaximal gait at 6 and 12 months quantified by peak oxygen consumption (Vo2peak) on graded exercise treadmill test and distance walked on the 6-minute walk test, respectively. Secondary outcomes were changes in lower extremity function, eGFR, albuminuria, glycemia, blood pressure, and body mass index. Among 99 participants, the mean age was 68 years, 62% were African American, and the mean eGFR was 33 mL/min/1.73 m2; 59% had diabetes, and 29% had coronary artery disease. Among those randomized to exercise, 59% of exercise sessions were attended in the initial 6 months. Exercise was well tolerated without excess occurrence of adverse events. At 6 months, aerobic capacity was higher among exercise participants (17.9 ± 5.5 vs 15.9 ± 7.0 mL/kg/min, P= 0.03), but the differences were not sustained at 12 months. The 6-minute walk distance improved more in the exercise group (adjusted difference: 98 feet [P= 0.02; P= 0.03 for treatment-by-time interaction]). The exercise group had greater improvements on the Timed Up and Go Test (P= 0.04) but not the Short Physical Performance Battery (P= 0.8). Planned sample size was not reached. Loss to follow-up and dropout were greater than anticipated. Among adults aged≥55 years with CKD stages 3b-4 and a high level of medical comorbidity, a 12-month program of in-center aerobic and resistance exercise training was safe and associated with improvements in physical functioning.

Data driven model of midportion achilles tendinopathy health created with factor analysis

BackgroundAchilles tendinopathy is a complex injury and the clinical presentation spans multiple different domains: physical and psychological symptoms, lower extremity function and tendon structure. A conceptual model of Achilles tendon health comprising these domains has been proposed in the literature. The aim of the study was to fit a model of Achilles tendinopathy using factor analysis and compare that to the conceptual model. An inclusive approach using a wide range of variables spanning multiple potential domains were included.MethodsParticipants (N = 99) with midportion Achilles tendinopathy were assessed with variables representing symptoms, physical function, tendon structure, metabolic syndrome, and psychologic symptoms. A Kaiser-Mayer-Olkin index was used to determine suitable variables for a subsequent exploratory factor analysis.ResultsA model emerged with an acceptable fit to the data (standardized root mean square of residuals = 0.078). Five uncorrelated factors emerged from the model and were labelled as biopsychosocial, lower extremity function, body size, load tolerance, and tendon structure. The total explained variance was 0.51 with the five factors explaining 0.14, 0.12, 0.10, 0.08, and 0.07 respectively. The results differed from the conceptual model as the factors of psychological variables and metabolic variables did not emerge from the analysis.ConclusionA data driven model of Achilles tendon health supports assessment of the clinical presentation over multiple domains. As the factors are uncorrelated, the results of assessment of, for example, tendon structure should not be expected to be associated with lower extremity function or biopsychosocial limitations. The results suggest that the Patient Reported Outcomes Measurement Information System, counter-movement jump height, body mass index, pain with hopping, and the tendon cross-sectional area can evaluate the five factors, respectively.Trial registrationRegistered on clinicaltrials.gov (Medicine NL of. ClinicalTrials.gov [Internet], 2018), ID number NCT03523325.

Justification of the parameters of the lister body

At present one of the leading places in the world is the development and mastering the production can simultaneously strip tillage and formation of irrigation throws and their use in the sowing of cucurbitaceous crops. The aim parameters the lister body combined strip-till of cucurbitaceous. Methods of classical mechanics have been applied in the research. In the process of research, the degree of layer turnover and soil crumbling by the lister body were determined, a special laboratory unit and strain gauge methods were used. Constructive the preparation fields from under cereals for strip sowing of gourds is the scheme with the lister body, ripper, right- and left-turning extreme bodies and furrow former located along the axis of symmetry. According to the results of theoretical studies, analytical dependences and mathematical models, allowing to determine the width of the lister body, the height of its blade, the size of the layer processed by the body, were obtained. Theoretical and experimental researches show that to provide the width of lister body should be 46 cm and its height 45.

Cognitive training via a mobile application to reduce some forms of body dissatisfaction in young females at high-risk for body image disorders: A randomized controlled trial

Body dissatisfaction has been related to Body Image Disorders (BIDs) such as Eating Disorders (EDs) and Body Dysmorphic Disorder (BDD). This study investigates the efficacy of a mHealth app in reducing body dissatisfaction, BDD/ED symptoms and related features. Ninety-five women who were identified as high-risk of developing BIDs (using the Structured Clinical Interview for DSM-5) were randomized into: immediate-use App (iApp group; n = 47) and delayed-use App (dApp group; n = 48). The iApp group started using the app at baseline for 16 days (T1). The dApp group started using the app at T1 for 16 days. Participants completed questionnaires at baseline (T0), 16 days from baseline (T1), and 32 days from baseline (T2). Repeated measure Multivariate Analysis of Variance (MANOVA) showed Group (iApp vs. dApp) × Time (T0 vs. T1) interactions indicating decrease in BDD symptoms and body dissatisfaction related to EDs in the iApp group at T1. The Reliable Change Index indicated changes on extreme body dissatisfaction/BDD symptoms for 34.74% of participants. Although preliminary, these findings highlight that a mHeatlh app might reduce BDD symptoms and body dissatisfaction related to EDs in women at high-risk for BIDs. Effects on ED symptoms and associated features seem more limited.

Postural stability, body composition and functional ability of the lower extremity in patients with lumbar degenerative spondylolisthesis

Although patients accessing rehabilitation services had been reported to have better functional ability of the lower limbs, postural stability, and low cardiovascular disease risk factors, updated data from developing countries is however vital for clinical practices. Hence, the aim of this study was to present the association between lower extremity functional ability (LEFA), stability, and body composition profiles in rehabilitative lumbar degenerative spondylolisthesis (LDS) patients considering age and gender. One hundred and twenty-four participants (45 females, 79 males), with a mean age of 56.45±11.13 years, volunteered for the study. Weight, height body fat percent (BFP), visceral fat, body mass index (BMI), resting systolic and diastolic blood pressure, and resting heart rate were measured while functional ability and stability tests were conducted on the participants. 53.4% were at least overweight; LEFA was below average, stability of both dominant and nondominant legs was very poor, blood pressure and heart rate were high. Women had high total body fat and visceral fat. Significant differences were observed in BMI (p=0.044) and BFP (p=0.035) based on age classification as well as BMI (p=0.000), BFP (p=0.000) and visceral fat (p=0.000) by gender. Overweight, high blood pressure, poor LEFA, and postural stability are crucial comorbidities of Ghanaian LDS patients in this study. Educationally and pragmatically comprehensive healthy lifestyle interventions of regular exercise regimes, adequate and quality nutrition, and occupational stress reduction would play major complementary roles in chiropractic treatment.

Evaluation of safety and efficacy outcomes of direct oral anticoagulants versus warfarin in normal and extreme body weights for the treatment of atrial fibrillation or venous thromboembolism.

Despite evolving evidence, the use of direct oral anticoagulants (DOACs) in patients with extremes of body weight remains controversial. This study aimed to measure the impact of DOACs compared to warfarin on safety and efficacy outcomes in extreme body weight patients. This multi-center, health system, retrospective study examined the outcomes of patients with all body weights and extreme body weights prescribed a DOAC (rivaroxaban, apixaban, dabigatran, edoxaban) or warfarin for atrial fibrillation or venous thromboembolism over a 9-year period. The primary outcome was a composite of thromboembolism, symptomatic recurrent VTE, or severe bleeding; analyzed by pre-determined BMI cutoffs. A total of 19,697 patients were included in the study: 11,604 in the DOAC group and in the 8093 in the warfarin group. 295 patients were underweight and 9108 patients were pre-obese to obese class 3. After adjusting for potential confounders, warfarin patients had higher odds of experiencing the composite outcome compared to DOAC patients (OR 1.337, 95% CI 1.212-1.475). Additionally, obese patients were 24.6% more likely to experience the outcome compared to normal BMI patients. Adjusted modeling showed that warfarin patients experienced higher bleed rates compared to DOAC patients (OR 1.432, 95% CI 1.266-1.620). Obese patients were less likely to be diagnosed with a bleed (OR 0.749, 95% CI 0.658-0.854), and underweight patients were more likely to be diagnosed with a bleed (OR 1.522, 95% CI 1.095-2.115) compared to normal BMI patients. In conclusion, DOACs for atrial fibrillation or VTE in patients with extreme body weights appear safe and effective when compared to warfarin.

Broad and Narrow Transdiagnostic Risk Factors in Eating Disorders: A Preliminary Study on an Italian Clinical Sample.

Eating disorders are multifaceted psychopathologies and the transdiagnostic approach is currently considered a useful framework to understand their complexity. This preliminary study aimed to investigate both broad (i.e., intolerance of uncertainty and emotion dysregulation) and narrow (i.e., extreme body dissatisfaction) transdiagnostic risk factors underlying eating disorders. 50 Italian female patients seeking treatment for an eating disorder were involved (Mage = 31.6 years ± 12.8, 18–65). They completed self-report measures assessing emotion regulation difficulties, intolerance of uncertainty, extreme body dissatisfaction, general psychological distress, and eating disorder symptomatology. To explore whether the abovementioned transdiagnostic factors predicted patients’ psychological distress and eating disorder symptoms, two linear regressions were performed. Emotion dysregulation emerged as the only significant predictor of distress, while extreme body dissatisfaction was the only significant predictor of overall eating disorder symptomatology. Then, to analyze the differences between patients with anorexia nervosa and bulimia nervosa in intolerance of uncertainty and emotion regulation problems, t-tests were conducted. The two groups differed significantly in intolerance of uncertainty levels only, with higher scores obtained by patients with anorexia nervosa. Overall, our findings suggest that emotion dysregulation and extreme body dissatisfaction may be relevant constructs in eating disorders in general, while intolerance of uncertainty may be more involved in restrictive eating disorders. The clinical implications of such results are discussed.
