Clinical Pharmacist Counselling Improves Long-term Medication Safety and Patient-reported Outcomes in Anti-TNF-treated Patients With Inflammatory Bowel Diseases: The Prospective, Randomized AdPhaNCED Trial.

BACKGROUND: Antitumor necrosis factor (anti-TNF) antibody treatment has led to marked improvements in the management of patients with inflammatory bowel diseases (IBDs). Nevertheless, anti-TNF therapy is associated with potential adverse drug reactions (ADRs). Our prospective, randomized trial investigated the effect of intensified clinical pharmacist counselling in a multidisciplinary team on medication safety in anti-TNF-treated IBD patients. METHODS: Patients with IBD with ongoing anti-TNF treatment were enrolled in our tertiary center AdPhaNCED trial and randomized to either receive conventional standard of care (control group) or additional clinical pharmacist counselling (intervention group) over 12 months. The primary end point consisted of the number and severity of ADRs associated with anti-TNF therapy. Secondary end points included patient satisfaction with medication information and medication safety. RESULTS: One hundred twenty-seven IBD patients were included in this study. Anti-TNF-related ADRs were significantly lower in the intervention compared with the control group (0.20 vs 0.32 [mean] ADR/patient/month, P = .006) after 12 months. The risk of more severe ADRs (Common Terminology Criteria for Adverse Events [CTCAE] grade ≥2) was significantly higher in the control compared with the intervention group (hazard ratio, 0.34; P = .001). The probability of ADR resolution (hazard ratio, 2.02; P < .001) and patient satisfaction with medication information (14.82 vs 11.60; P < .001) were significantly higher in the intervention group compared with the control group. CONCLUSIONS: Our study results demonstrate that intensified pharmacist counselling significantly reduces the occurrence and severity of therapy-related ADRs and improves patient satisfaction. Clinical pharmacists should therefore be part of a holistic approach to IBD care delivered by a multidisciplinary team.

The prospective, randomized AdPhaNCED trial demonstrated that anti-TNF-treated IBD patients had diminished and less severe drug-related adverse reactions and higher patient satisfaction when they received intensified pharmacist counselling in comparison with conventional standard of care over 12 months.

Inflammation, lipid dysregulation, and transient receptor potential cation channel subfamily V member 4 signaling perpetuate chronic vulvar pain.

ABSTRACT: Localized provoked vulvodynia is characterized by chronic vulvar pain that disrupts every aspect of the patient's life. Pain is localized to the vulvar vestibule, a specialized ring of tissue immediately surrounding the vaginal opening involved in immune defense. In this article, we show inflammation is the critical first step necessary for the generation of pain signals in the vulva. Inflammatory stimuli alone or combined with the transient receptor potential cation channel subfamily V member 4 (TRPV4) agonist 4α-phorbol 12,13-didecanoate stimulate calcium flux into vulvar fibroblast cells. Activity is blocked by the TRPV4 antagonist HC067047, denoting specificity to TRPV4. Using lipidomics, we found pro-resolving lipids in the vulvar vestibule were dysregulated, characterized by a reduction in pro-resolving mediators and heightened production of inflammatory mediators. We demonstrate specialized pro-resolving mediators represent a potential new therapy for vulvar pain, acting on 2 key parts of the disease mechanism by limiting inflammation and acutely inhibiting TRPV4 signaling.

The association of alcohol use and positive and negative urgency to same day objective binge eating in emerging adults.

Introduction: Objective binge eating and problematic alcohol use often co-occur and are common behaviors in emerging adults. Both behaviors are thought to be driven by affect regulation processes. Objective binge eating often occurs in the context of increasing or acute negative affect, and often occurs in solitude. Alcohol use in emerging adults can also be associated with negative affect regulation. However, in contrast to objective binge eating, a large body of research indicates that there are positively valenced pathways to alcohol use in this age group. Emerging adults often drink socially, to enhance enjoyment, and in the context of positive mood. We propose that one pathway to objective binge eating in this developmental period is through alcohol use itself, such that emerging adults who consume alcohol and who are more likely to act impulsively in the context of positive emotion (i.e., have high levels of positive urgency) may be more likely to binge eat following drinking. Methods: We collected data using ecological momentary assessment in 106 undergraduates on positive and negative affect, motives for drinking and eating, and alcohol use and objective binge eating, in addition to baseline questionnaires of impulsivity. Results: There were no significant changes in affect prior to drinking in this sample. Alcohol use at one time point significantly increased odds of objective binge eating at a later time point in the same day. Individual differences in positive urgency, the tendency to act rashly while experiencing positive affect, were also associated with increased odds of objective binge eating that occurred after alcohol use. Individual differences in negative urgency, the tendency to act rashly after experiencing negative affect, did not have a main effect on objective binge episodes, but did interact with alcohol use to increase the odds of objective binge eating following drinking. The vast majority of drinking episodes prior to objective binge eating were social drinking episodes, and participants most commonly endorsed "to have fun" as a reason for drinking. Discussion: Results suggest that alcohol consumption may increase risk for objective binge eating in emerging adults.

The development and validation of a multidimensional organisational trust measure.

Motivation for the study: Workplaces are changing with employees increasingly working remotely and flexibly, which has created larger physical distance between team members. This shift has consequences for trust research and implications for how trust is built and maintained between employees and leaders. Research design: Three studies collectively aimed to demonstrate how employee trust in leaders has adapted to a hybrid work environment. A validation of a seminal multidimensional employee trust in leaders measure was conducted. Also, an alternative multidimensional measure was developed, piloted, and then validated using exploratory and confirmatory factor analyses. Main findings: Findings showed the Affective and Cognitive Trust scale not to be sufficiently reliable or valid after testing with a sample working in a hybrid model of virtual and face to face work environments. However, the new measure demonstrated good reliability and validity. Implication: Findings reinforced that there are behavioural and relational elements to organisational trust, and there are two discreet dimensions to trustworthy behaviour: communication and authenticity.

The interaction between land-use change and fire regimes, directly and indirectly, affects the urban avian assemblages of Darwin, Australia.

The interaction between environmental stressors may be a greater threat to biota than any individual ecological threat on its own. Land-use change and inappropriate fire regimes are known to pose great challenges to biodiversity conservation worldwide. Despite much research being conducted into their singular impacts on ecosystems, very few have investigated how their interaction may be affecting the biota of a region. We used data from surveys in 1998/2000 and 2019/2020 to compare the feeding guild assemblages of bird communities in different habitats within the greater Darwin region. By compiling two sets of spatial data, land-use change, and fire history mapping, we were able to investigate their interaction and impact on the avian assemblages in the Darwin urban area. Using Generalized Linear Mixed Models (GLMM) we found that an increase in urbanization significantly affected fire occurrence across study sites. Furthermore, we found that the interaction between land-use change and fire regimes had a significant effect on species that primarily feed on fruit. We conclude that while an increase in urbanization did not directly affect the avian assemblages, the impact of land-use change on the fire regimes indirectly impacted urban bird community structures.

Predictors of current suicidal ideation in a multi-diagnostic sample of individuals with eating disorders.

BACKGROUND: Individuals with eating disorders (EDs) have high rates of suicidal ideation (SI) and attempts (SA). Fasting, body dissatisfaction, binge eating and purging have been associated with SI in non-clinical samples, individuals with anorexia nervosa or low-weight EDs, and a multi-diagnostic sample. However, few studies have examined how ED symptoms contribute to risk for SI in conjunction with other well-established risk factors, such as nonsuicidal self-injury (NSSI) and past SA. The aim of this study was to examine which ED symptoms contribute unique risk for current SI in a multi-diagnostic, clinical sample when statistically adjusting for gender, NSSI, past SA, and past SI. METHODS: We conducted a chart review of 166 individuals who presented for ED treatment at an outpatient facility and signed informed consent. Initial intake interviews were coded for the presence versus absence of fasting, fear of weight gain, binge eating, purging, excessive exercise, restriction, body checking, self-weighing, and body dissatisfaction, as well as NSSI, past SA, past SI, and current SI. RESULTS: A total of 26.5% of the sample endorsed current SI. In a logistic regression analysis, identifying as male (n = 17) or having a non-binary gender identity (n = 1), the presence of fasting, and past SI were all significantly associated with increased odds of current SI, whereas excessive exercise significantly decreased odds of current SI. Fasting was equally common across all diagnostic groups. CONCLUSIONS: Future research should establish the temporal relationship between fasting and SI to better inform intervention.

Proteasomes of Autophagy-Deficient Cells Exhibit Alterations in Regulatory Proteins and a Marked Reduction in Activity.

Autophagy and the ubiquitin proteasome system are the two major processes for the clearance and recycling of proteins and organelles in eukaryotic cells. Evidence is accumulating that there is extensive crosstalk between the two pathways, but the underlying mechanisms are still unclear. We previously found that autophagy 9 (ATG9) and 16 (ATG16) proteins are crucial for full proteasomal activity in the unicellular amoeba Dictyostelium discoideum. In comparison to AX2 wild-type cells, ATG9-and ATG16- cells displayed a 60%, and ATG9-/16- cells a 90%, decrease in proteasomal activity. Mutant cells also showed a significant increase in poly-ubiquitinated proteins and contained large ubiquitin-positive protein aggregates. Here, we focus on possible reasons for these results. Reanalysis of published tandem mass tag-based quantitative proteomic results of AX2, ATG9-, ATG16-, and ATG9-/16- cells revealed no change in the abundance of proteasomal subunits. To identify possible differences in proteasome-associated proteins, we generated AX2 wild-type and ATG16- cells expressing the 20S proteasomal subunit PSMA4 as GFP-tagged fusion protein, and performed co-immunoprecipitation experiments followed by mass spectrometric analysis. The results revealed no significant differences in the abundance of proteasomes between the two strains. However, we found enrichment as well as depletion of proteasomal regulators and differences in the ubiquitination of associated proteins for ATG16-, as compared to AX2 cells. Recently, proteaphagy has been described as a means to replace non-functional proteasomes. We propose that autophagy-deficient D. discoideum mutants suffer from inefficient proteaphagy, which results in the accumulation of modified, less-active, and also of inactive, proteasomes. As a consequence, these cells exhibit a dramatic decrease in proteasomal activity and deranged protein homeostasis.

Segment-Based Spotting of Bowel Sounds Using Pretrained Models in Continuous Data Streams.

We analyse pretrained and non-pretrained deep neural models to detect 10-seconds Bowel Sounds (BS) audio segments in continuous audio data streams. The models include MobileNet, EfficientNet, and Distilled Transformer architectures. Models were initially trained on AudioSet and then transferred and evaluated on 84 hours of labelled audio data of eighteen healthy participants. Evaluation data was recorded in a semi-naturalistic daytime setting including movement and background noise using a smart shirt with embedded microphones. The collected dataset was annotated for individual BS events by two independent raters with substantial agreement (Cohen's Kappa κ = 0.74). Leave-One-Participant-Out cross-validation for detecting 10-second BS audio segments, i.e. segment-based BS spotting, yielded a best F1 score of 73% and 67%, with and without transfer learning respectively. The best model for segment-based BS spotting was EfficientNet-B2 with an attention module. Our results show that pretrained models could improve F1 score up to 26%, in particular, increasing robustness against background noise. Our segment-based BS spotting approach reduces the amount of audio data to be reviewed by experts from 84 h to 11 h, thus by  âˆ¼ 87%.

Utility of the coned-down lateral view of the lumbosacral spine.

OBJECTIVE: At certain institutions and radiology practices, a routine lumbar radiographic exam may include 3 views: AP, lateral, and coned-down lateral of the lumbosacral junction. The purpose of this study is to determine whether the third coned-down-lateral view adds significant diagnostic information regarding pathology at the L4-L5 and L5-S1 levels. MATERIALS AND METHODS: This retrospective study includes patients (n = 74) who had a 3-view radiographic exam of the lumbar spine, as well as a CT or MRI within six months. The AP and lateral views were reviewed by three radiologists, both with and without the use of the third, coned-lateral view. Subsequently, the CT and MRI performed within 6 months was reviewed, and the results compared. The primary outcome was detection of abnormal alignment and disc disease at the L4-L5 and L5-S1 levels. RESULTS: For the combined findings of alignment and disc disease at each L4-L5 and L5-S1, there was disagreement between the 2-view and 3-view exams on 18 (of 296) evaluations. Of these 18, the 2-view and the 3-view exam each made positive findings on 9. By the binomial test, there is no evidence that either the 2-view or the 3-view exam tends to make more findings than the other (p = 1). Compared to CT/MRI, the 2-view exam agrees on 74.7 % of evaluations and the 3-view exam agrees on 75.3 %. There is therefore no evidence that the 3-view exam is more accurate than the 2-view exam. CONCLUSION: Elimination of the coned-down lateral view could reduce radiation exposure and imaging-related costs while maintaining diagnostic quality.

Zirconia-Toughened Alumina Ceramic Wear Particles Do Not Elicit Inflammatory Responses in Human Macrophages.

Ten percent of patients undergoing total hip arthroplasty (THA) require revision surgery. One of the reasons for THA are wear particles released from the implants that can activate the immune defense and cause osteolysis and failure of the joint implant. The discrepancies between reports on toxicity and immunogenicity of the implant materials led us to this study in which we compared toxicity and immunogenicity of well-defined nanoparticles from Al2O3, zirconia-toughened alumina (ZTA), and cobalt chrome (CoCr), a human THP-1 macrophage cell line, human PBMCs, and therefrom-derived primary macrophages. None of the tested materials decreased the viability of THP-1 macrophages nor human primary macrophages at the 24 h time point, indicating that at concentrations from 0.05 to 50 µm3/cell the tested materials are non-toxic. Forty-eight hours of treatment of THP-1 macrophages with 5 µm3/cell of CoCr and Al2O3 caused 8.3-fold and 4.6-fold increases in TNF-α excretion, respectively, which was not observed for ZTA. The comparison between THP-1 macrophages and human primary macrophages revealed that THP-1 macrophages show higher activation of cytokine expression in the presence of CoCr and Al2O3 particles than primary macrophages. Our results indicate that ZTA is a non-toxic implant material with no immunogenic effects in vitro.

Data-Driven Radiogenomic Approach for Deciphering Molecular Mechanisms Underlying Imaging Phenotypes in Lung Adenocarcinoma: A Pilot Study.

The heterogeneity of lung tumor nodules is reflected in their phenotypic characteristics in radiological images. The radiogenomics field employs quantitative image features combined with transcriptome expression levels to understand tumor heterogeneity molecularly. Due to the different data acquisition techniques for imaging traits and genomic data, establishing meaningful connections poses a challenge. We analyzed 86 image features describing tumor characteristics (such as shape and texture) with the underlying transcriptome and post-transcriptome profiles of 22 lung cancer patients (median age 67.5 years, from 42 to 80 years) to unravel the molecular mechanisms behind tumor phenotypes. As a result, we were able to construct a radiogenomic association map (RAM) linking tumor morphology, shape, texture, and size with gene and miRNA signatures, as well as biological correlates of GO terms and pathways. These indicated possible dependencies between gene and miRNA expression and the evaluated image phenotypes. In particular, the gene ontology processes "regulation of signaling" and "cellular response to organic substance" were shown to be reflected in CT image phenotypes, exhibiting a distinct radiomic signature. Moreover, the gene regulatory networks involving the TFs TAL1, EZH2, and TGFBR2 could reflect how the texture of lung tumors is potentially formed. The combined visualization of transcriptomic and image features suggests that radiogenomic approaches could identify potential image biomarkers for underlying genetic variation, allowing a broader view of the heterogeneity of the tumors. Finally, the proposed methodology could also be adapted to other cancer types to expand our knowledge of the mechanistic interpretability of tumor phenotypes.

Caregiver and adolescent intuitive eating behavior: associations with weight change during family-based treatment for anorexia nervosa.

PURPOSE: Intuitive eating (IE) is an adaptive eating construct for which little research exists in eating disorder (ED) samples. IE is negatively correlated with disordered eating behaviors in healthy adolescents and adults, and similar associations have been found in adults with EDs. This study aims to examine IE in a treatment seeking sample of adolescents and their caregivers to understand the role of IE in weight gain during FBT. METHODS: Descriptive statistics and bivariate correlations were calculated in a sample of 47 pairs of adolescent patients and their caregivers who initiated outpatient FBT at a large academic medical center. Analyses examined associations between caregiver and adolescent IE on the Intuitive Eating Scale (IES), change in percent expected body weight (%EBW) by session 4 and end of treatment (EOT), clinical impairment, and ED pathology. RESULTS: Significant correlations were found between aspects of adolescent IE, ED symptoms, and clinical impairment. Caregiver IES scores (Reliance on Hunger and Satiety Cues, Body-Food Choice Congruence, IES Total) were negatively related to adolescent ED symptoms (EDE-Q Weight Concerns, EDE-Q Shape Concerns, EDE-Q Global) at baseline. Caregiver IE (Eating for Physical Rather than Emotional Reasons) was positively associated with adolescent weight gain at FBT session 4 and EOT, even when statistically adjusting for gender and initial level of care. CONCLUSION: Study results were consistent with past research indicating adolescent IE is negatively associated with ED behaviors, cognitions, and impairment. This study is the first to provide evidence that caregiver IE is positively associated with adolescent weight gain in FBT and is the first to provide evidence that caregiver IE is negatively related to adolescent ED symptoms. Future research should examine adolescent and caregiver IE throughout FBT to understand the role of IE in treatment response. LEVEL OF EVIDENCE: Level III: Evidence obtained from cohort or case-control analytic studies.

The role of discrimination and adverse childhood experiences in disordered eating.

BACKGROUND: In clinical research, there has been a call to move beyond individual psychosocial factors towards identifying cultural and social factors that inform mental health. Similar calls have been made in the eating disorders (ED) field underscoring the need to understand larger sociocultural influences on EDs. Discrimination is a social stressor that may influence mental health in similar ways to traumatic or adverse childhood experiences (ACEs). Given the high rates of EDs and discrimination among marginalized groups, it is vital to understand the role of discrimination and ACEs as predictors of ED symptoms in these populations. The aim of this study is to examine how perceived discrimination predicts ED pathology when statistically adjusting for gender, race, and ACEs. METHODS: The diverse study sample consisted of 331 undergraduate students from a longitudinal cohort study (ages 18-24; 66% female; 35% White/non-Hispanic). Participants completed measures of everyday discrimination, ACEs, and ED pathology. RESULTS: Following adjustment for multiple statistical comparisons, the frequency of daily discrimination predicted all ED symptoms above and beyond history of ACEs. In follow-up analyses, number of reasons for discrimination predicted cognitive restraint and purging. Differences in ED symptomatology were found based on the reason for discrimination, gender, and race. Specifically, those who experienced weight discrimination endorsed higher scores on all ED symptoms, and those experiencing gender discrimination endorsed higher body dissatisfaction, cognitive restraint, and restriction. People of color endorsed higher restriction, while female participants endorsed higher scores on all ED symptom with the exception of cognitive restraint. CONCLUSION: Discrimination is a salient risk factor for ED symptoms even when accounting for individuals' history of ACEs. Future research should utilize an intersectional approach to examine how perceived discrimination affects ED pathology over time. (Word count: 234).

Adverse childhood experiences (ACEs) increase risk for eating disorders (EDs). Discrimination based on race, gender, and gender and sexual identity is also linked to ED behaviors. This paper examined whether discrimination impacted ED behaviors when ACEs were considered to understand how they both might play a role in risk for EDs. Findings suggest that experiences of discrimination may have a greater impact on eating disorder symptoms in college students than a history of ACEs. More research is needed to understand the negative impacts of discrimination on eating disorders, in addition to history of trauma. Clinicians should attend to the ways discrimination may impact their clients' eating disorder behaviors, and whether individuals experience bias or discrimination when seeking eating disorder treatment.

Examining the relationship of eating disorder symptoms and perfectionism in men and women using two assessments of eating pathology.

Eating disorder (ED) pathology in men is not as well understood or studied as ED pathology in women. One potential reason for this is that most of the traditional assessments used for EDs were developed for and validated with exclusively female samples, meaning that symptoms in men are not as well represented or measured. There are consistent associations between perfectionism and ED symptoms in women, but less is known regarding how these relationships function in men. This study examined whether the relationship of perfectionism to ED symptoms varies by gender using the Eating Disorder Examination-Questionnaire (EDE-Q) and the Eating Pathology Symptom Inventory (EPSI). The EPSI has multiple dimensions that may better capture the presentation of ED symptoms in men. Participants were recruited from a large public university and through Amazon MechanicalTurk. Participants completed a survey battery that included the two eating measures and the self-oriented perfectionism scale from the Hewitt and Flett Multidimensional Perfectionism Scale. Data were analyzed using independent samples t-tests and structural equation modeling. There were significant positive associations between self-oriented perfectionism and all dimensions measured by the EDE-Q and the EPSI. The models were invariant across gender. Implications for further research were discussed.

Characterization of Filigree Additively Manufactured NiTi Structures Using Micro Tomography and Micromechanical Testing for Metamaterial Material Models.

This study focuses on the influence of additive manufacturing process strategies on the specimen geometry, porosity, microstructure and mechanical properties as well as their impacts on the design of metamaterials. Filigree additively manufactured NiTi specimens with diameters between 180 and 350 µm and a nominal composition of Ni50.9Ti49.1 (at %) were processed by laser powder bed fusion in a first step. Secondly, they structures were characterized by optical and electron microscopy as well as micro tomography to investigate the interrelations between the process parameters, specimen diameters and microstructure. Each specimen was finally tested in a micro tensile machine to acquire the mechanical performance. The process strategy had, besides the resulting specimen diameter, an impact on the microstructure (grain size) without negatively influencing its quality (porosity). All specimens revealed a superelastic response while the critical martensitic phase transition stress decreased with the applied vector length. As a conclusion, and since the design of programmable metamaterials relies on the accuracy of FEM simulations, precise and resource-efficient testing of filigree and complex structures remains an important part of creating a new type of metamaterials with locally adjusted material behavior.

Intestinal Barrier Healing Is Superior to Endoscopic and Histologic Remission for Predicting Major Adverse Outcomes in Inflammatory Bowel Disease: The Prospective ERIca Trial.

BACKGROUND & AIMS: Endoscopic and histologic remission have emerged as key therapeutic goals in the management of inflammatory bowel diseases (IBD) that are associated with favorable long-term disease outcomes. Here, we prospectively compared the predictive value of barrier healing with endoscopic and histologic remission for predicting long-term disease behavior in a large cohort of patients with IBD in clinical remission. METHODS: At baseline, patients with IBD in clinical remission underwent ileocolonoscopy with assessment of intestinal barrier function by confocal endomicroscopy. Endoscopic and histologic disease activity, as well as barrier healing, was prospectively assessed along established scores. During subsequent follow-up, patients were closely monitored for clinical disease activity and the occurrence of major adverse outcomes (MAOs): disease flares, IBD-related hospitalization or surgery, and initiation or dose escalation of systemic steroids, immunosuppressants, small molecules, or biological therapy. RESULTS: The final analysis included 181 patients, 100 with Crohn's disease [CD] and 81 with ulcerative colitis (UC). During a mean follow-up of 35 (CD) and 25 (UC) months, 73% of patients with CD and 69% of patients with UC experienced at least 1 MAO. The probability of MAO-free survival was significantly higher in patients with IBD with endoscopic remission compared with endoscopically active disease. In addition, histologic remission predicted MAO-free survival in patients with UC but not CD. Barrier healing on endomicroscopy was superior to endoscopic and histologic remission for predicting MAO-free survival in both UC and CD. CONCLUSIONS: Barrier healing is associated with decreased risk of disease progression in patients with clinically remittent IBD, with superior predictive performance compared with endoscopic and histologic remission. Analysis of barrier function might be considered as a future treatment target in clinical trials. CLINICALTRIALS: gov number, NCT05157750.

Burn Resuscitation Practices in North America: Results of the Acute Burn ResUscitation Multicenter Prospective Trial (ABRUPT).

OBJECTIVES: ABRUPT was a prospective, noninterventional, observational study of resuscitation practices at 21 burn centers. The primary goal was to examine burn resuscitation with albumin or crystalloids alone, to design a future prospective randomized trial. SUMMARY BACKGROUND DATA: No modern prospective study has determined whether to use colloids or crystalloids for acute burn resuscitation. METHODS: Patients ≥18 years with burns ≥ 20% total body surface area (TBSA) had hourly documentation of resuscitation parameters for 48 hours. Patients received either crystalloids alone or had albumin supplemented to crystalloid based on center protocols. RESULTS: Of 379 enrollees, two-thirds (253) were resuscitated with albumin and one-third (126) were resuscitated with crystalloid alone. Albumin patients received more total fluid than Crystalloid patients (5.2 ± 2.3 vs 3.7 ± 1.7 mL/kg/% TBSA burn/24 hours), but patients in the Albumin Group were older, had larger burns, higher admission Sequential Organ Failure Assessment (SOFA) scores, and more inhalation injury. Albumin lowered the in-to-out (I/O) ratio and was started ≤12 hours in patients with the highest initial fluid requirements, given >12 hours with intermediate requirements, and avoided in patients who responded to crystalloid alone. CONCLUSIONS: Albumin use is associated with older age, larger and deeper burns, and more severe organ dysfunction at presentation. Albumin supplementation is started when initial crystalloid rates are above expected targets and improves the I/O ratio. The fluid received in the first 24 hours was at or above the Parkland Formula estimate.

Design and Manufacturing of a Metal-Based Mechanical Metamaterial with Tunable Damping Properties.

In the present work, a novel concept for metallic metamaterials is presented, motivated by the creation of next-generation reversible damping systems that can be exposed to various environmental conditions. For this purpose, a unit cell is designed that consists of a parallel arrangement of a spring and snap-fit mechanism. The combination of the two concepts enables damping properties one order of magnitude higher than those of the constituting metal material. The spring element stores elastic energy while the snap-fit allows to absorb and dissipate energy and to reach a second stable state. Different configurations of single unit cells and connected cell assemblies are manufactured by laser powder bed fusion using Ti6Al4V powder. The dimensioning is supported by finite element modelling and the characteristic properties of the unit cells are studied in cyclic compression experiments. The metamaterial exhibits damping properties in the range of polymeric foams while retaining its higher environmental resistance. By variation of selected geometrical parameters, either bistable or self-recovering characteristics are achieved. Therefore, a metamaterial as an assembly of the described unit cells could offer a high potential as a structural element in future damping or energy storage systems operating at elevated temperatures and extreme environmental conditions.

Internet-delivered eating disorders prevention program for adolescent girls with type 1 diabetes: Acceptable and feasible.

BACKGROUND: Adolescents with type 1 diabetes are at significantly increased risk for eating disorders and few interventions exist. OBJECTIVE: This study examined the feasibility, acceptability, and preliminary effects of an internet-based eating disorders prevention program adapted specifically for adolescent girls with type 1 diabetes. PARTICIPANTS AND METHODS: Thirty-five girls (16.2 ± 1.1 years) participated Body Project (T1D Style), a 4-week program consisting of four adolescent sessions focused on promoting illness acceptance, challenging sociocultural body image pressures, increasing social support, and teaching assertive communication. Caregivers participated in one session focused on fostering body image positivity and a healthy relationship with food. Pre-intervention, post-intervention, and 3-month follow-up surveys assessed disordered eating, body dissatisfaction, thin-ideal internalization, diabetes acceptance, diabetes distress, and quality of life. Cohen's d effect sizes were calculated at post-intervention and follow-up. Program acceptability was assessed at post-intervention. Manual fidelity and homework completion were monitored. RESULTS: High manual fidelity, retention, and homework completion were achieved. Quantitative and qualitative feedback from teens and caregivers suggested high acceptability. Large effects (d = 1.35-0.83) were observed for dieting, body dissatisfaction, diabetes distress, diabetes acceptance, and diabetes-related quality of life at post-intervention, with large-medium effects (d = 1.16-0.58) at follow-up. Medium-small effects (d = 0.49-0.78) at post-intervention were observed for diabetes-specific disordered eating and thin-ideal internalization, with effects maintained at follow-up. CONCLUSIONS: Results support the acceptability and feasibility of this targeted eating disorders prevention program for adolescent girls with type 1 diabetes. Future clinical trials are warranted to determine its effectiveness compared to a control condition.
