This paper presents an exploratory evaluation of pilot nutrition education programs, Plan Shop Save Cook (PSSC). Behavior change between two nutrition education programs, Buy Eat Live Healthy (BELH; n=92 and PSSC; n=42), was examined using pre- and post-program questionnaire responses. Both programs resulted in significant improvement in food resource management (FRM) behaviors; however, there was no significant difference in the amount of change between the programs. Qualitative data suggests participants perceived label reading as the most useful information provided in the PSSC programs. The current findings suggest short-term behavior change can be achieved with a limited dose program.

Objectives Informing research participants of the results of studies in which they took part is viewed as an ethical imperative. However, there is little guidance in the literature about how to do this. The Fluoxetine Or Control Under Supervision trial randomised 3127 patients with a recent acute stroke to 6 months of fluoxetine or placebo and was published in the Lancet on 5 December 2018. The trial team decided to inform the participants of the results at exactly the same time as the Lancet publication, and also whether they had been allocated fluoxetine or placebo. In this report, we describe how we informed participants of the results.Design In the 6-month and 12-month follow-up questionnaires, we invited participants to provide an email address if they wished to be informed of the results of the trial. We re-opened our trial telephone helpline between 5 December 2018 and 31 March 2019.Setting UK stroke services.Participants 3127 participants were randomised. 2847 returned 6-month follow-up forms and 2703 returned 12-month follow-up forms; the remaining participants had died (380), withdrawn consent or did not respond.Results Of those returning follow-up questionnaires, a total of 1845 email addresses were provided and a further 50 people requested results to be sent by post. Results were sent to all email and postal addresses provided; 309 emails were returned unrecognised. Seventeen people replied, of whom three called the helpline and the rest responded by email.Conclusion It is feasible to disseminate results of large trials to research participants, though only around 60% of those randomised wanted to receive the results. The system we developed was efficient and required very little resource, and could be replicated by trialists in the future.Trial registration number ISRCTN83290762; Post-results.

Family-professional partnerships are essential for promoting positive outcomes for students with and without disabilities. However, the extent to which professional preparation standards address skills to cultivate family-professional partnerships is unclear. Without this knowledge, it is challenging to understand the preparation of education professionals in developing partnerships with families. The purpose of this study is to explore the relation between preparation standards and two factors of family-professional partnerships (i.e., enhancing connection and enhancing capacity) for general and special education teachers as well as other education professionals. The authors use expert review to identify and evaluate 159 professional preparation standards from 15 Specialized Professional Associations and the Interstate New Teacher Assessment and Support Consortium in relation to the two factors. Findings showed no significant differences among the standards in relation to enhancing connection among family-professional partnerships. Standards related exclusively to special education, younger students, or teachers (vs other education professionals) were significantly more likely to reflect enhancing capacity among family-professional partnerships. Implications for future research and practice are discussed.

In higher education settings, the central function of a disability resource professional (DRP) is determining accommodations in collaboration with disabled college students, making their role in the outcomes of students with disabilities paramount. Despite this importance, research on the process of determining accommodations is minimal, and professional guidance on the matter can be interpreted in varied ways, leading DRPs to rely on their "professional judgment" to reach final decisions. What subtly informs this professional judgment, particularly concerning DRPs' positionalities and student identities, is largely unexplored. The purpose of this study was to explore the perspectives of U.S. DRPs related to their accommodation decision-making processes, experiences, and perceptions. Based on the results of this exploratory national survey of DRPs, accommodation decision-making processes described by participants can be divided into four components: (a) forming initial opinions, (b) engaging with students, (c) consulting with others, and (d) making final decisions. Notably, participants' perceptions of positionality and identities in the accommodations process situated those of students to be more heavily considered than their own. Following a presentation of findings, the authors conclude with implications for the field and recommendations for future research.

While higher education disability resource professionals are required to use considerable professional judgment to make accommodation-related decisions, there is a lack of guidance on how to make these decisions. Because disability resource professionals commonly ascribe to a "common-sense standard" when making accommodation-related decisions, the purpose of this study was to investigate disability resource professionals' perceptions of the influence of their identities and experiences in accommodation-related decision-making. Using a qualitative approach, researchers engaged in semi-structured interviews with a total of 13 disability resource professionals across the United States. Participants described identities and experiences as influential in their work, discussed the impact of holding both convergent and divergent identities with students, and shared strategies in response to the influence of these identities and experiences. The authors conclude with implications for the disability resources field as well as directions for future research.

To replace the current professional paradigm of higher education disability resources, socially-just disability resources emerged as the next step for the field to progress relative to creating experiences for students with disabilities that are not only accessible and equitable but also socially-just. Overall, descriptions of socially-just disability resources take the social model approach a step further by directly mobilizing disability resource professionals to organize for greater change in higher education to holistically address barriers with an ideal outcome of reducing the need for accommodations altogether. However, because this is a novel framework, there is a paucity of research regarding its implementation. The purpose of this study was to understand what the ideal implementation of socially just disability resources would entail and how these practices can be sustained. Following a review of the findings from an appreciative inquiry initiative conducted with one disability resource center, implications are discussed.

FERPA (1974) privacy laws protect undocumented Latinx learners with disabilities (ULWD) from disclosing their immigration status. The right to maintain anonymity provided by FERPA, however, potentially results in challenges in identifying and supporting the unique needs ULWD in home and school environments. Due, in part, to a lack of information, school professionals may view ULWD from deficit perspective perpetuated by the dominant narrative. In an effort to uncover what does exist within the literature of ULWD and better understand their experiences in school systems, the purpose of this review was to bring to light the available peer-reviewed and dissertation research about ULWD published in the U.S. between 2002 and 2021. Three research questions guided this review: (1) What was the purpose of research studies concerning ULWD? (2) Who were the participants, what were the research methods, and theoretical frameworks used? and (3) What were the common themes across the studies? Findings indicate that there is little research addressing the needs of ULWD and their family caregivers, with existing literature consistently calling for further research on this population. Implications for future research are discussed.

Summary: Autoimmune diseases such as lupus are characterized by polyclonal B cell activation, leading to the production of autoantibodies. The mechanism leading to B cell dysregulation is unclear; however, the defect may lie in selection within germinal centers (GCs). GC B cells cycle between proliferation and mutation in the dark zone and selection in the light zone (LZ). Temporal assessment of GCs from mice with either persistent infection or lupus showed an accumulation of LZ B cells. Yet, only in lupus, GC B cells exhibited reduced proliferation and progressive loss of MYC and FOXO1, which regulate zonal recycling and differentiation. As lupus progressed, decreased mutational frequency and repertoire diversity were associated with reduced responsiveness to CD40 signaling, despite accumulation of plasma cells. Collectively, these findings suggest that lupus disease progression coincides with an intrinsic defect in LZ B cell signaling, altering the zonal recycling, selection, and differentiation of autoreactive B cells.

The failure of cartilages to fuse, particularly in the case of articular cartilage under conditions of repair is due to morphological and structural constraints of the tissue. Factors that impede integration include, non-vascularisation, low cellularity, and proteoglycan in the surrounding extracellular matrix acting as a natural barrier to cellular migration. We hypothesised that brief activation of a catabolic cascade by cytokines followed by culture under anabolic conditions would promote tissue fusion in a ring-disk model of cartilage integration. Our results show that transient exposure to 10 ng mL-1 interleukin-1β, followed by two weeks post-culture under anabolic conditions, enhanced cartilage-cartilage integration compared to untreated explants. Quantitative PCR analysis of catabolism-related genes ADAMTS4 and MMP13 showed both were transiently upregulated and these findings correlated with evidence of extracellular matrix remodelling. At the level of histology, we observed chondrocytes readily populated the interfacial matrix between fused explants in interleukin-1β treated explants, whereas in control explants this region was relatively acellular in comparison. Catabolic cytokine treated explants exhibited 29-fold greater adhesive strength (0.859 MPa versus 0.028 MPa, P

Abstract Background A challenge facing many Academic Health Centers (AHCs) attempting to revise health professions education to include the impact of racism as a social and structural determinant of health (SSDoH) is a lack of broad faculty expertise to reinforce and avoid undermining learning modules addressing this topic. To encourage an institutional culture that is in line with new anti-racism instruction, we developed a six-part educational series on the history of racism in America and its impact on contemporary health inequities for teaching structural competency to health professions academicians. Methods We developed a six-hour elective continuing education (CE) series for faculty and staff with the following objectives: (1) describe and discuss race as a social construct; (2) describe and discuss the decolonization of the health sciences and health care; (3) describe and discuss the history of systemic racism and structural violence from a socio-ecological perspective; and (4) describe and discuss reconciliation and repair in biomedicine. The series was spread over a six-month period and each monthly lecture was followed one week later by an open discussion debriefing session. Attendees were assessed on their understanding of each objective before and after each series segment. Results We found significant increases in knowledge and understanding of each objective as the series progressed. Attendees reported that the series helped them grapple with their discomfort in a constructive manner. Self-selected attendees were overwhelmingly women (81.8%), indicating a greater willingness to engage with this material than men. Conclusions The series provides a model for AHCs looking to promote anti-racism and structural competency among their faculty and staff.

Abstract The intestinal extracellular matrix (ECM) helps maintain appropriate tissue barrier function and regulate host-microbial interactions. Chondroitin sulfate- and dermatan sulfate-glycosaminoglycans (CS/DS-GAGs) are integral components of the intestinal ECM, and alterations in CS/DS-GAGs have been shown to significantly influence biological functions. Although pathologic ECM remodeling is implicated in inflammatory bowel disease (IBD), it is unknown whether changes in the intestinal CS/DS-GAG composition are also linked to IBD in humans. Our aim was to characterize changes in the intestinal ECM CS/DS-GAG composition in intestinal biopsy samples from patients with IBD using mass spectrometry. We characterized intestinal CS/DS-GAGs in 69 pediatric and young adult patients (n = 13 control, n = 32 active IBD, n = 24 IBD in remission) and 6 adult patients. Here, we report that patients with active IBD exhibit a significant decrease in the relative abundance of CS/DS isomers associated with matrix stability (CS-A and DS) compared to controls, while isomers implicated in matrix instability and inflammation (CS-C and CS-E) were significantly increased. This imbalance of intestinal CS/DS isomers was restored among patients in clinical remission. Moreover, the abundance of pro-stabilizing CS/DS isomers negatively correlated with clinical disease activity scores, whereas both pro-inflammatory CS-C and CS-E content positively correlated with disease activity scores. Thus, pediatric patients with active IBD exhibited increased pro-inflammatory and decreased pro-stabilizing CS/DS isomer composition, and future studies are needed to determine whether changes in the CS/DS-GAG composition play a pathogenic role in IBD.

Two randomized complete block design experiments evaluated the influence that varying degrees of ingredient inclusion accuracy in a finishing diet have on growth performance and carcass traits. Treatments included (1) normal inclusion tolerance with a 0.454 kg tolerance for all ingredients (CON) or (2) variable inclusion tolerance where each ingredient was randomly increased or decreased but the targeted as-fed quantity for the daily delivery was met (VAR). In Experiment. 1, black Angus heifers (n = 60; initial shrunk BW = 460 ± 26.2 kg) were used in a 112 d experiment. Ten pens in total (5 pens/treatment, 6 heifers/pen) were used. The targeted diet (DM basis) consisted of high-moisture ear corn (75%), dried distiller’s grains (20%), and a liquid supplement (5%). As-fed inclusion rates for DDGS and LS varied from formulated targets by −20, −15, −10, −5, 0, +5, +10, +15 or +20%. The HMEC inclusion was adjusted so that the targeted as-fed amount of the diet was delivered daily. Treatment did not alter ADG, DMI, G:F, HCW, dressing percentage, rib-eye area, rib fat, USDA marbling score, KPH, yield grade, retail yield, empty body fat, or body weight at 28% estimated EBF, nor liver abscess prevalence or severity (p ≥ 0.15). In Exp. 2, Charolais–Angus cross steers (n = 128; initial shrunk BW = 505 ± 32.1 kg) were used in a 94 d experiment. Steers were assigned to pens (8 pens/treatment; 8 steers/pen) and one of the two management strategies used in Exp. 1 was employed. Ractopamine HCl was fed (300 mg per head daily) during the final 28 d. Diets consisted of (DM basis) dry-rolled corn (63%), dried distiller’s grains plus solubles (15%), liquid supplement (5%), grass hay (7%), and corn silage (10%). Ingredient inclusions were randomized in the same manner as Exp. 1, except LS inclusion was held constant. Corn silage inclusion was adjusted so that the targeted as-fed amount of the diet was delivered each day. Steers from VAR had increased (p = 0.01) DMI, but similar (p = 0.75) ADG resulting in reduced (p ≤ 0.02) G:F and growth-performance-predicted Net Energy for maintenance and gain. Treatment did not influence (p ≥ 0.38) HCW, dressing percentage, rib-eye area, rib fat, KPH, yield grade, retail yield, empty body fat, or body weight at 28% estimated EBF. A tendency for an increased USDA marbling score (p = 0.08) was noted in VAR. Under the conditions of this experiment, randomly altering ingredient proportions can impact growth performance and efficiency measures depending upon the type of finishing diet fed.

Currently, we face an exponentially increasing interest in immersion, especially sensory–driven immersion, mainly due to the rapid development of ideas and business models centered around a digital virtual universe as well as the increasing availability of affordable immersive technologies for education, communication, and entertainment. However, a clear definition of ‘immersion’, in terms of established neurocognitive concepts and measurable properties, remains elusive, slowing research on the human side of immersive interfaces.To address this problem, we propose a conceptual, taxonomic model of attention in immersion. We argue (a) modeling immersion theoretically as well as studying immersion experimentally requires a detailed characterization of the role of attention in immersion, even though (b) attention, while necessary, cannot be a sufficient condition for defining immersion. Our broader goal is to characterize immersion in terms that will be compatible with established psychophysiolgical measures that could then in principle be used for the assessment and eventually the optimization of an immersive experience. We start from the perspective that immersion requires the projection of attention to an induced reality, and build on accepted taxonomies of different modes of attention for the development of our two–competitor model. The two–competitor model allows for a quantitative implementation and has an easy graphical interpretation. It helps to highlight the important link between different modes of attention and affect in studying immersion.

In the context of aging and age-associated neurodegenerative disorders, the brain’s extracellular matrix (ECM) serves as a critical regulator for neuronal health and cognitive function. Within the extracellular space, proteoglycans and their glycosaminoglycan attachments play essential roles in forming, stabilizing, and protecting neural circuits throughout neurodevelopment and adulthood. Recent studies in rodents reveal that chondroitin sulfate-glycosaminoglycan (CS-GAG) containing perineuronal nets (PNNs) exhibit both structural and compositional differences throughout the brain. While animal studies are illuminating, additional research is required to translate these interregional PNN/CS-GAG variations to human brain tissue. In this perspective article, we first investigate the translational potential for interregional CS-GAG variances across species as novel targets for region-specific therapeutic development. We specifically focus on the observation that alterations in brain PNN-associated CS-GAGs have been linked with the progression of Alzheimer’s disease (AD) neuropathology in humans, but these changes have not been fully recapitulated in rodent models of this disease. A second highlight of this perspective article investigates whether AD-associated shifts in CS-GAGs in humans may be dependent on region-specific baseline differences in CS-GAG sulfation patterning. The current findings begin to disentangle the intricate relationships between the interregional differences in brain PNN/CS-GAG matrices across species, while emphasizing the need to better understand the close relationship between dementia and changes in brain CS-GAG sulfation patterns in patients with AD and related dementias.

College decision-making among students without disabilities has been well-documented, highlighting factors that influence student decisions to attend college, which college they select, types of support networks, and their pathways to degree completion. Yet, despite increased college enrollment among students with disabilities (SWD) in the United States, little is known about the factors that influence the decision to attend college and the decision-making process overall among SWD. Therefore, the purpose of this qualitative study was to understand factors that influenced college decision-making among this population. Through interviews and a focus group, participants described engaging in cost-benefit decision-making, uncertainty about financial aid and other loan policies, the influence of family and community, and personal disability considerations in college choice. Participants also provided recommendations for future students navigating college decision-making and for universities providing information to SWD and their families throughout the process. Implications for policy and practice, future research, and limitations are reported.

Abstract Background Bronchopulmonary dysplasia (BPD), an inflammatory-mediated chronic lung disease, is common in extremely preterm infants born before 28 weeks’ gestation and is associated with an increased risk of adverse neurodevelopmental and respiratory outcomes in childhood. Effective and safe prophylactic therapies for BPD are urgently required. Systemic corticosteroids reduce rates of BPD in the short term but are associated with poorer neurodevelopmental outcomes if given to ventilated infants in the first week after birth. Intratracheal administration of corticosteroid admixed with exogenous surfactant could overcome these concerns by minimizing systemic sequelae. Several small, randomized trials have found intratracheal budesonide in a surfactant vehicle to be a promising therapy to increase survival free of BPD. The primary objective of the PLUSS trial is to determine whether intratracheal budesonide mixed with surfactant increases survival free of bronchopulmonary dysplasia (BPD) at 36 weeks’ postmenstrual age (PMA) in extremely preterm infants born before 28 weeks’ gestation. Methods An international, multicenter, double-blinded, randomized trial of intratracheal budesonide (a corticosteroid) mixed with surfactant for extremely preterm infants to increase survival free of BPD at 36 weeks’ postmenstrual age (PMA; primary outcome). Extremely preterm infants aged

This study examined the experiences of parents of young adults (YAs) with disabilities and co-occurring mental health disorders (D/MH). As these students leave high school, parents become primary providers of support, yet little is known about the challenges these parents face. Researchers used a basic interpretive approach to analyze qualitative data from parents of YAs with D/MH. Participants described (a) experience seeking YA's diagnoses, (b) impact of YA needs, (c) parent needs, and (d) recommendations for professionals and parents. Implications for practice include greater collaboration and training between school and mental health professionals and mental health training to professionals and families. Future research should explore the experiences of family units to determine coping strategies used across family members.

Butyric acid is attributed to gastrointestinal epithelial development and health and two studies were conducted to determine if supplementing encapsulated butyric acid and zinc (BZ) in lambs abruptly transitioned to a finishing diet has effects on growth performance, efficiency of dietary net energy utilization, rumen morphometrics, small intestinal histology, and carcass traits. Polypay wethers (n = 84; initial shrunk body weight = 38.8 kg ± 4.8 kg) were used in a randomized complete block design study. Wethers were abruptly transitioned from a high roughage-based diet to a 100% concentrate-based diet and dietary treatments were 0 or 2 g BZ/kg of diet dry matter. Study 1 evaluated growth performance and carcass traits of lambs over a 59.5 d feeding period, and Study 2 evaluated changes in rumen morphometrics and small intestine histology in serial harvested lambs. Wethers supplemented with BZ had increased body wall thickness, decreased calculated boneless closely trimmed retail cuts, and decreased red meat yield (p ≤ 0.03) compared to non-supplemented wethers. Linear effects (p ≤ 0.01) for harvest date were observed for most rumen and small intestine measurements. Supplementing wethers with BZ did not improve growth performance, carcass traits, or rumen and small intestine measurements. The effects of BZ supplementation on fat deposition in ruminants should be further investigated.

Aging is a natural process but may lead to aging anxiety due to physical and mental health changes. Aging anxiety is more prevalent among African Americans compared to Whites. This study aimed to investigate the correlation between aging anxiety, its four constructs including fear of older adults (contact with older adults), psychological concerns (personal/internal issues), physical appearance (physical changes), and fear of loss (loss of autonomy and social relationships), with the different types of physical activity (PA), as well as the attitudes toward PA. A total of 178 African American adults aged 40 years and older completed an online Qualtrics survey. The Lasher and Faulkender survey was utilized for the purposes of obtaining data on aging anxiety. PA was measured using questions derived from the National Health Interview Survey questionnaire and miscellaneous Questions for PA attitudes. The results revealed that fear of loss was the most anxiety-inducing factor among the participants. Females were more fearful of older adults and more anxious about aging than males. Possessing an enjoyable attitude toward PA was associated with less fear of older adults, fewer psychological concerns, and a lower total score of aging anxiety. Physical appearance constructs were correlated with age and strengthening exercises. Younger participants were more worried about their appearance than older participants. Fear of loss was higher among single and lower-income participants. Interventions and mental health programs should consider addressing the fear of loss and promoting a positive attitude toward PA to alleviate aging anxiety among middle-aged and older African Americans.

Objectives: To identify the proportion of young people experiencing homelessness who are immunized against vaccine-preventable diseases, and to evaluate the impact of a nurse-led immunization program to improve vaccination coverage in this population. Methods: A retrospective audit of electronic medical records included 400 participants aged 15 to 24 years who had an encounter with the Young People’s Health Service, a nurse-led clinic co-located with a specialist youth homelessness service in Melbourne, Australia, between February 2019 and May 2021. Results: Integrating an immunization nurse within a youth specialist homelessness service increased the percentage of young people who were up-to-date with routine vaccinations from 6.0% (n = 24) to 38.8% (n = 155). Intersecting social determinants of health that increased participants’ risk of vaccine preventable diseases, and of missing routine vaccines, were common. Conclusions: Incomplete coverage of routine vaccines is common in young people accessing homelessness services, and this coverage was improved when young people encountered an immunization nurse while accessing support from a specialist youth homelessness service. As a service model, nurse-led community health clinics co-located within homelessness providers can improve vaccination coverage, and therefore health outcomes, of young people experiencing or at risk of homelessness.

Background Heparin-induced thrombocytopenia (HIT) is a common differential diagnosis in cardiothoracic surgery. The latex immunoturbidimetric assay (LIA) is an enhanced immunoassay that has recently been introduced for the detection of total HIT immunoglobulin and retains a higher specificity of 95% compared to the enzyme-linked immunosorbent assay. Objectives To investigate if a semiquantitative relationship exists between increasing LIA levels beyond the current positivity threshold and its correlation to positive serotonin release assay results in cardiothoracic surgery. Methods This was a multicenter, observational cohort of cardiothoracic surgery patients initiated on anticoagulation with heparin-based products. To conduct sensitivity and specificity analysis of LIA values, HIT positive was defined as a LIA value ≥1 unit/mL and HIT negative was defined as a LIA level

The objective of the study was to determine the influence that initial BW has on growth performance responses, efficiency of dietary net energy (NE) utilization, and carcass traits in feedlot steers. Charolais×Red Angus steers (n = 70) selected from a larger single-source group were used in a 209-d growing-finishing feedlot experiment. Steers were assigned to two groups based on initial BW (light initial weight, LIW = 273 ± 16.0 kg; heavy initial weight, HIW = 356 ± 14.2 kg) and allotted into 10 pens (n = 7 steers per pen; 5 pens per experimental group) the within pen standard deviation for LIW was from 14.1 kg to 20.9 kg and for HIW was from 13.7 kg to 16.0 kg. Steers were fed a common diet once daily. Experimental data were analyzed as a randomized complete block design with pen as the experimental unit. LIW steers had a greater cumulative HH change (p = 0.04). A treatment × day interaction (p = 0.05) was observed for HH with HIW steers having a greater HH at all time points. Final BW and carcass-adjusted (HCW/0.625) BW were greater for HIW steers by 13.1% and 13.4% respectively (p ≤ 0.01). HIW steers had a greater DMI (p = 0.01) compared to LIW. Cumulative ADG was greater for HIW by 3% (p = 0.04). LIW steers had better feed conversion (p = 0.01). HIW steers had greater (p ≤ 0.05) HCW, marbling scores, and yield grade (YG), with decreased REA/HCW (p = 0.01) compared to LIW. The distribution of USDA Yield Grade was altered by initial BW (p = 0.04). No differences were detected (p ≥ 0.22) for the distribution of Quality grade nor liver abscess prevalence and severity. Regression coefficients did not differ between LIW and HIW for urea space calculations of empty body water, fat, or protein (p ≥ 0.70). A quadratic response was noted for empty body fat (EBF), empty body water (EBH20), and carcass protein (CP). In conclusion, HIW steers had greater growth, but poorer feed efficiency compared to LIW steers. Steers with a HIW produced fatter carcasses with a greater degree of marbling.

AimsFractures of the distal radius are common, and form a considerable proportion of the trauma workload. We conducted a study to examine the patterns of injury and treatment for adult patients presenting with distal radius fractures to a major trauma centre serving an urban population.MethodsWe undertook a retrospective cohort study to identify all patients treated at our major trauma centre for a distal radius fracture between 1 June 2018 and 1 May 2021. We reviewed the medical records and imaging for each patient to examine patterns of injury and treatment. We undertook a binomial logistic regression to produce a predictive model for operative fixation or inpatient admission.ResultsOverall, 571 fractures of the distal radius were treated at our centre during the study period. A total of 146 (26%) patients required an inpatient admission, and 385 surgical procedures for fractures of the distal radius were recorded between June 2018 and May 2021. The most common mechanism of injury was a fall from a height of one metre or less. Of the total fractures, 59% (n = 337) were treated nonoperatively, and of those patients treated with surgery, locked anterior-plate fixation was the preferred technique (79%; n = 180).ConclusionThe epidemiology of distal radius fractures treated at our major trauma centre replicated the classical bimodal distribution described in the literature. Patient age, open fractures, and fracture classification were factors correlated with the decision to treat the fracture operatively. While most fractures were treated nonoperatively, locked anterior-plate fixation remains the predominant method of fixation for fractures of the distal radius; this is despite questions and continued debate about the best method of surgical fixation for these injuries.Cite this article: Bone Jt Open 2022;3(8):623–627.

Gait-stabilizing devices (GSDs) are effective at preventing falls, but people are often reluctant to use them until after experiencing a fall. Inexpensive, convenient, and effective methods for predicting which patients need GSDs could help improve adoption. The purpose of this study was to determine if a Wii Balance Board (WBB) can be used to determine whether or not patients use a GSD. We prospectively recruited participants ages 70-100, some who used GSDs and some who did not. Participants first answered questions from the Modified Vulnerable Elders Survey, and then completed a grip-strength test using a handgrip dynamometer. Finally, they were asked to complete a series of four 30-second balance tests on a WBB in random order: (1) eyes open, feet apart; (2) eyes open, feet together; (3) eyes closed, feet apart; and (4) eyes closed, feet together. The four-test series was repeated a second time in the same random order. The resulting data, represented as 25 features extracted from the questionnaires and the grip test, and data from the eight balance tests, were used to predict a subject's GSD use using generalized functional linear models based on the Bernoulli distribution. 268 participants were consented; 62 were missing data elements and were removed from analysis; 109 were not GSD users and 97 were GSD users. The use of velocity and acceleration information from the WBB improved upon predictions based solely on grip strength, demographic, and survey variables. The WBB is a convenient, inexpensive, and easy-to-use device that can be used to recommend whether or not patients should be using a GSD.

Background and Aims. Smoke exposure occurred in the Adelaide Hills region in December 2019 due to a wildfire, when wine grapes were peppercorn-size green berries. Previously, pre-veraison smoke exposure had been identified through model experiments as unlikely to affect grape composition, whereas smoke exposure after veraison can have a major effect on wine flavour. Hence the effects of pre-veraison smoke on grape and wine composition, and smoky sensory properties of wine were investigated. Methods and Results. Chardonnay, Pinot Noir and Shiraz were investigated and eight blocks with varied smoke exposure were selected for each cultivar. Berries were sampled initially four weeks after the fire and at harvest, and mature grapes were made into unoaked wines. Established smoke exposure markers, phenolic glycosides, were found in berries at pre-veraison and at harvest from the high smoke exposure sites, with concentrations well above those found in non-smoke exposed fruit. Volatile phenols were also elevated in grapes at harvest. The resulting red wines from some exposure vineyards were high in volatile phenols, glycosides and smoky flavours. However, most of the Chardonnay wines expressed much less smoky flavours, despite similar levels of smoke exposure of grapes. Conclusions. Pre-veraison smoke exposure can result in elevated concentrations of volatile phenols and their glycosidic metabolites in grape berries and wine and cause strong smoky flavour in wine. Significance. The wine sector and land management agencies responsible for controlled burns need to consider the effect of smoke from fires near vineyards even very early in the growing season.

Child dental caries (i.e., cavities) are a major preventable health problem in most high-income countries. The aim of this study was to compare the extent of inequalities in child dental caries across four high-income countries alongside their child oral health policies. Coordinated analyses of data were conducted across four prospective population-based birth cohorts (Australia, n = 4085, born 2004; Québec, Canada, n = 1253, born 1997; Rotterdam, the Netherlands, n = 6690, born 2002; Southeast Sweden, n = 7445, born 1997), which enabled a high degree of harmonization. Risk ratios (adjusted) and slope indexes of inequality were estimated to quantify social gradients in child dental caries according to maternal education and household income. Children in the least advantaged quintile for income were at greater risk of caries, compared to the most advantaged quintile: Australia: AdjRR = 1.18, 95%CI = 1.04-1.34; Québec: AdjRR = 1.69, 95%CI = 1.36-2.10; Rotterdam: AdjRR = 1.67, 95%CI = 1.36-2.04; Southeast Sweden: AdjRR = 1.37, 95%CI = 1.10-1.71). There was a higher risk of caries for children of mothers with the lowest level of education, compared to the highest: Australia: AdjRR = 1.18, 95%CI = 1.01-1.38; Southeast Sweden: AdjRR = 2.31, 95%CI = 1.81-2.96; Rotterdam: AdjRR = 1.98, 95%CI = 1.71-2.30; Québec: AdjRR = 1.16, 95%CI = 0.98-1.37. The extent of inequalities varied in line with jurisdictional policies for provision of child oral health services and preventive public health measures. Clear gradients of social inequalities in child dental caries are evident in high-income countries. Policy related mechanisms may contribute to the differences in the extent of these inequalities. Lesser gradients in settings with combinations of universal dental coverage and/or fluoridation suggest these provisions may ameliorate inequalities through additional benefits for socio-economically disadvantaged groups of children.

The intuitive fuzzy set has found important application in decision-making and machine learning. To enrich and utilize the intuitive fuzzy set, this study designed and developed a deep neural network-based glaucoma eye detection using fuzzy difference equations in the domain where the retinal images converge. Retinal image detections are categorized as normal eye recognition, suspected glaucomatous eye recognition, and glaucomatous eye recognition. Fuzzy degrees associated with weighted values are calculated to determine the level of concentration between the fuzzy partition and the retinal images. The proposed model was used to diagnose glaucoma using retinal images and involved utilizing the Convolutional Neural Network (CNN) and deep learning to identify the fuzzy weighted regularization between images. This methodology was used to clarify the input images and make them adequate for the process of glaucoma detection. The objective of this study was to propose a novel approach to the early diagnosis of glaucoma using the Fuzzy Expert System (FES) and Fuzzy differential equation (FDE). The intensities of the different regions in the images and their respective peak levels were determined. Once the peak regions were identified, the recurrence relationships among those peaks were then measured. Image partitioning was done due to varying degrees of similar and dissimilar concentrations in the image. Similar and dissimilar concentration levels and spatial frequency generated a threshold image from the combined fuzzy matrix and FDE. This distinguished between a normal and abnormal eye condition, thus detecting patients with glaucomatous eyes. [ABSTRACT FROM AUTHOR]

The MOPITT (Measurements of Pollution in the Troposphere) satellite instrument has been making nearly continuous observations of atmospheric carbon monoxide (CO) since 2000. Satellite observations of CO are routinely used to analyze emissions from fossil fuels and biomass burning, as well as the atmospheric transport of those emissions. Recent enhancements to the MOPITT retrieval algorithm have resulted in the release of the version 8 (V8) product. V8 products benefit from updated spectroscopic data for water vapor and nitrogen used to develop the operational radiative transfer model and exploit a new method for minimizing retrieval biases through parameterized radiance bias correction. In situ datasets used for algorithm development and validation include the NOAA (National Oceanic and Atmospheric Administration) and HIPPO (HIAPER Pole-to-Pole Observations) datasets used for earlier MOPITT validation work in addition to measurements from the ACRIDICON-CHUVA (Aerosol, Cloud, Precipitation, and Radiation Interactions and Dynamics of Convective Cloud Systems – Cloud processes of the main precipitation systems in Brazil: A contribution to cloud resolving modeling and to the GPM (Global Precipitation Measurement)), KORUS-AQ (The Korea-United States Air Quality Study), and ATom (The Atmospheric Tomography Mission) programs. Validation results illustrate clear improvements with respect to long-term bias drift and geographically variable retrieval bias. For example, whereas bias drift for the V7 thermal-infrared (TIR)-only product exceeded 0.5 % yr−1 for levels in the upper troposphere (e.g., at 300 hPa), bias drift for the V8 TIR-only product is found to be less than 0.1 % yr−1 at all levels. Also, whereas upper-tropospheric (300 hPa) retrieval bias in the V7 TIR-only product exceeded 10 % in the tropics, corresponding V8 biases are less than 5 % (in terms of absolute value) at all latitudes and do not exhibit a clear latitudinal dependence.

In 2020, COVID-19 disrupted all aspects of society across the globe including healthcare, employment, social interactions, and education. In many parts of the world, abrupt school closures caught teachers off guard, as they were forced to immediately shift their practices from in-person to online instruction with little-to-no preparation. Furthermore, during this time, many parents of school-aged children vacillated between multiple roles associated with their employment, household caregiving activities, and supporting their children at home. These challenges were especially challenging for teachers and parents of students with severe disabilities. The purpose of this study was to explore the experiences of U.S. teachers of students with severe disabilities regarding interacting with parents during the COVID-19 pandemic, including when schools initially closed in March 2020 and then reopened in September of 2020. This manuscript outlines six key themes highlighting parent–teacher interactions: (a) parents directing school decisions, (b) teacher inability to meet parent expectations, (c) parent–teacher communication, (d) parents as teachers, (e) parent exhaustion, and (f) teacher helplessness.

Background: Myanmar is a country undergoing rapid transitions in health. Its national strategic policy for young people’s health is being revised but there is a paucity of population data to inform local priorities and needs. Objective: In this paper we describe a comprehensive profile of adolescent health in Myanmar to focus policy and health actions. Methods: We used available primary data, and modelled estimates from the GBD 2017, to describe health outcomes (mortality and morbidity), health risks and determinants for adolescents in Myanmar between 1990–2017. A governance group of key stakeholders guided the framing of the study, interpretation of findings, and recommendations. Results: Overall health has improved for adolescents in Myanmar since 1990, however adolescent mortality remains high, particularly so for older adolescent males; all-cause mortality rate for 10–24 years was 70 per 100,000 for females and 149 per 100,000 for males (16,095 adolescent deaths in 2017). Overall, the dominant health problems were injuries for males and non-communicable disease for females in a context of ongoing burden of communicable and nutritional diseases for both sexes, and reproductive health needs for females. Health risks relating to undernutrition (thinness and anaemia) remain prevalent, with other health risks (overweight, binge alcohol use, and substance use) relatively low by global and regional standards but increasing. Gains have been made in social determinants such as adolescent fertility and modern contraception use; however, advances have been more limited in secondary education completion and engagement in employment and post education training. Conclusions: These results highlight the need to focus current efforts on addressing disease and mortality experienced by adolescents in Myanmar, with a specific focus on injury, mental health and non-communicable disease.

Advances in nanotechnology have enabled the design of nanotherapeutic platforms that could address the challenges of targeted delivery of active therapeutic agents to the central nervous system (CNS). While the majority of previous research studies on CNS nanotherapeutics have focused on neurons and endothelial cells, the predominant resident immune cells of the CNS, microglia, are also emerging as a promising cellular target for neurodegeneration considering their prominent role in neuroinflammation. Under normal physiological conditions, microglia protect neurons by removing pathological agents. However, long-term exposure of microglia to stimulants will cause sustained activation and lead to neuronal damage due to the release of pro-inflammatory agents, resulting in neuroinflammation and neurodegeneration. This Perspective highlights criteria to be considered when designing microglia-targeting nanotherapeutics for the treatment of neurodegenerative disorders. These criteria include conjugating specific microglial receptor-targeting ligands or peptides to the nanoparticle surface to achieve targeted delivery, leveraging microglial phagocytic properties, and utilizing biocompatible and biodegradable nanomaterials with low immune reactivity and neurotoxicity. In addition, certain therapeutic agents for the controlled inhibition of toxic protein aggregation and for modulation of microglial activation pathways can also be incorporated within the nanoparticle structure without compromising stability. Overall, considering the multifaceted disease mechanisms of neurodegeneration, microglia-targeted nanodrugs and nanotherapeutic particles may have the potential to resolve multiple pathological determinants of the disease and to guide a shift in the microglial phenotype spectrum toward a more neuroprotective state.
