Database, Features, and Machine Learning Model to Identify Thermally Driven Metal-Insulator Transition Compounds

Metal-insulator transition (MIT) compounds are materials that may exhibit insulating or metallic behavior, depending on the physical conditions, and are of immense fundamental interest owing to their potential applications in emerging microelectronics. There is a dearth of thermally-driven MIT materials, however, which makes delineating these compounds from those that are exclusively insulating or metallic challenging. Here we report a material database comprising temperature-controlled MITs (and metals and insulators with similar chemical composition and stoichiometries to the MIT compounds) from high quality experimental literature, built through a combination of materials-domain knowledge and natural language processing. We featurize the dataset using compositional, structural, and energetic descriptors, including two MIT relevant energy scales, an estimated Hubbard interaction and the charge transfer energy, as well as the structure-bond-stress metric referred to as the global-instability index (GII). We then perform supervised classification, constructing three electronic-state classifiers: metal vs non-metal (M), insulator vs non-insulator (I), and MIT vs non-MIT (T). We identify two important descriptors that separate metals, insulators, and MIT materials in a 2D feature space: the average deviation of the covalent radius and the range of the Mendeleev number. We further elaborate on other important features (GII and Ewald energy), and examine how they affect classification of binary vanadium and titanium oxides. We discuss the relationship of these atomic features to the physical interactions underlying MITs in the rare-earth nickelate family. Last, we implement an online version of the classifiers, enabling quick probabilistic class predictions by uploading a crystallographic structure file

The course of mental health problems in children presenting with abdominal pain in general practice

Objective. To investigate the course of mental health problems in children presenting to general practice with abdominal pain and to evaluate the extent to which abdominal pain characteristics during follow-up predict the presence of mental health problems at 12 months' follow-up. Design. A prospective cohort study with one-year follow-up. Setting. 53 general practices in the Netherlands, between May 2004 and March 2006. Subjects. 281 children aged 4-17 years. Main outcome measures. The presence of a depressive problem, an anxiety problem, and multiple non-specific somatic symptoms at follow-up and odds ratios of duration, frequency, and severity of abdominal pain with these mental health problems at follow-up. Results. A depressive problem persisted in 24/74 children (32.9%; 95% CI 22.3-44.9%), an anxiety problem in 13/43 (30.2%; 95% CI 17.2-46.1%) and the presence of multiple non-specific somatic symptoms in 75/170 children (44.1%; 95% CI 36.7-51.6%). None of the abdominal pain characteristics predicted a depressive or an anxiety problem at 12 months' follow-up. More moments of moderate to severe abdominal pain predicted the presence of multiple nonspecific somatic symptoms at follow-up. Conclusions. In one-third of the children presenting to general practice for abdominal pain, anxiety and depressive problems persist during one year of follow-up. Characteristics of the abdominal pain during the follow-up period do not predict anxiety or depressive problems after one-year follow-up. We recommend following over time children seen in primary care with abdominal pain

Using telehealth clinical case vignettes to enhance clinical confidence and competence in veterinary students

Veterinarians contribute substantially to the health of their patients and enhance the communities in which they live. Delivery of veterinary curricula continues to evolve to ensure that veterinary graduates are prepared to meet their professional obligations on Day One of their careers. In this study, veterinary practitioners were recruited to deliver telehealth case rounds to veterinary students at Kansas State University and Texas A&M University. Case discussions were hosted virtually once per month in the 2020–2021 and 2021–2022 academic years for a total of 16 sessions. Each presenting practitioner was instructed to develop a brief presentation for a case routinely seen in their practice, and to discuss important clinical decision points in diagnosis, treatment and management. Cases could also highlight important ethical or communication issues encountered in veterinary medicine. The overall goals of this project were to increase the quantity and diversity of clinical cases to which veterinary students were exposed during their professional training and to evaluate the feasibility and acceptability of telehealth technology as a teaching strategy. Student participants were surveyed to determine the effectiveness of telehealth sessions in increasing overall confidence and competence in case management, and veterinary presenters were surveyed to determine motivations for participating in the project and perceived value of the telehealth sessions. More than 95% of students indicated that participation in telehealth sessions increased their clinical confidence and competence. Presenting practitioners unanimously indicated that they would participate in similar instruction in the future. Recommendations are provided to improve the educational experience for future adopters of telehealth teaching sessions

Large genomic differences between Moraxella bovoculi isolates acquired from the eyes of cattle with infectious bovine keratoconjunctivitis versus the deep nasopharynx of asymptomatic cattle

Large genomic differences between Moraxella bovoculi isolates acquired from the eyes of cattle with infectious bovine keratoconjunctivitis versus the deep nasopharynx of asymptomatic cattle. Veterinary Research, 47, 11. doi:10.1186/s13567-016-0316-2Moraxella bovoculi is a recently described bacterium that is associated with infectious bovine keratoconjunctivitis (IBK) or "pinkeye" in cattle. In this study, closed circularized genomes were generated for seven M. bovoculi isolates: three that originated from the eyes of clinical IBK bovine cases and four from the deep nasopharynx of asymptomatic cattle. Isolates that originated from the eyes of IBK cases profoundly differed from those that originated from the nasopharynx of asymptomatic cattle in genome structure, gene content and polymorphism diversity and consequently placed into two distinct phylogenetic groups. These results suggest that there are genetically distinct strains of M. bovoculi that may not associate with IBK

Early motion and directed exercise (EMADE) versus usual care post ankle fracture fixation: study protocol for a pragmatic randomised controlled trial

Background: Following surgical fixation of ankle fractures, the traditional management has included immobilisation for 6 weeks in a below-knee cast. However, this can lead to disuse atrophy of the affected leg and joint stiffness. While early rehabilitation from 2 weeks post surgery is viewed as safe, controversy remains regarding its benefits. We will compare the effectiveness of early motion and directed exercise (EMADE) ankle rehabilitation, against usual care, i.e. 6 weeks’ immobilisation in a below-knee cast. Method/design: We have designed a pragmatic randomised controlled trial (p-RCT) to compare the EMADE intervention against usual care. We will recruit 144 independently living adult participants, absent of tissue-healing comorbidities, who have undergone surgical stabilisation of isolated Weber B ankle fractures. The EMADE intervention consists of a non-weight-bearing progressive home exercise programme, complemented with manual therapy and education. Usual care consists of immobilisation in a non-weight-bearing below-knee cast. The intervention period is between week 2 and week 6 post surgery. The primary outcome is the Olerud and Molander Ankle Score (OMAS) patient-reported outcome measure (PROM) at 12 weeks post surgery. Secondary PROMs include the EQ-5D-5 L questionnaire, return to work and return to driving, with objective outcomes including ankle range of motion. Analysis will be on an intention-to-treat basis. An economic evaluation will be included. Discussion: The EMADE intervention is a package of care designed to address the detrimental effects of disuse atrophy and joint stiffness. An advantage of the OMAS is the potential of meta-analysis with other designs. Within the economic evaluation, the cost-utility analysis, may be used by commissioners, while the use of patient-relevant outcomes, such as return to work and driving, will ensure that the study remains pertinent to patients and their families. As it is being conducted in the clinical environment, this p-RCT has high external validity. Accordingly, if significant clinical benefits and cost-effectiveness are demonstrated, EMADE should become a worthwhile treatment option. A larger-scale, multicentre trial may be required to influence national guidelines. Trial registration: ISRCTN, ID: ISRCTN11212729. Registered retrospectively on 20 March 2017

A mixed treatment comparison meta-analysis of metaphylaxis treatments for bovine respiratory disease in beef cattle

A mixed treatment comparison meta-analysis of metaphylaxis treatments for bovine respiratory disease in beef cattle. Journal of Animal Science, 95(2), 626-635. doi:10.2527/jas2016.1062The objective of this project was to evaluate the effects of antimicrobials approved for parenteral metaphylactic use in feeder and stocker calves on morbidity and mortality for bovine respiratory disease with the use of a mixed treatment comparison meta-analysis. An initial literature review was conducted in April 2016 through Pubmed, Agricola, and CAB (Commonwealth Agricultural Bureau) for randomized controlled trials for metaphylaxis antimicrobial administered parentally to incoming feedlot or stocker calves within 48 h of arrival. The final list of publications included 29 studies, with a total of 37 trials. There were 8 different metaphylactic antimicrobials. Final event outcomes were categorized into bovine respiratory disease (BRD) morbidity cumulative incidence d 1 to <= 60 of the feeding period, BRD morbidity cumulative incidence d 1 to closeout of the feeding period, BRD mortality cumulative incidence d 1 to closeout of the feeding period, and BRD retreatment cumulative incidence morbidity d 1 to closeout of the feeding period. Network meta-analysis combined direct and indirect evidence for all the event outcomes to determine mean odds ratio (OR) with 95% credibility intervals (CrIs) for all metaphylactic antimicrobial comparisons. The "upper tier" treatment arms for morbidity d 1 to <= 60 included tulathromycin, gamithromycin, and tilmicosin. For BRD mortality cumulative incidence d 1 to closeout and BRD retreatment morbidity d 1 to closeout, classifying the treatment arms into tiers was not possible due to overlapping 95% CrIs. The results of this project accurately identified differences between metaphylactic antimicrobials, and metaphylactic antimicrobial options appear to offer different outcomes on BRD morbidity and mortality odds in feedlot cattle

Comparison of the Physical Attributes of Plant-Based Ground Beef Alternatives to Ground Beef

Objective: The objective of this study was to evaluate the physical attributes of three different plant-based, ground beef alternatives in comparison to ground beef of three different fat percentages. Study Description: Ground beef of three different fat percentages, a retail pea protein-based ground beef alternative, and a traditional soy-based ground beef alternative were obtained from retail stores (n = 15 lots/treatment). Samples from 15 lots of a foodservice soy protein-based ground beef alternative were obtained from a foodservice chain. All samples were fabricated into 0.25 lb patties assigned to one of four assays: color analysis, texture profile analysis, shear force, and pressed juice percentage. Results: When evaluating raw color, traditional ground beef alternative had the highest (P \u3c 0.05) a* value and were redder when compared to all other treatments, with retail ground beef alternative having the lowest (P \u3c 0.05) a* value. Traditional and retail ground beef alternative had the highest (P \u3c 0.05) a* value, while foodservice ground beef alternative, and 30% and 10% fat ground beef had the lowest (P \u3c 0.05) a* value for cooked surface color. For texture attributes, retail and foodservice ground beef alternatives had lower (P \u3c 0.05) values for cohesiveness, gumminess, hardness, and chewiness, as well as higher (P \u3c 0.05) values for springiness, than all other treatments evaluated. For shear force, the three ground beef alternatives were more tender (P \u3c 0.05) than all three ground beef treatments, with foodservice and retail ground beef alternatives being more tender (P \u3c 0.05) than all treatments. The three ground beef treatments had greater (P \u3c 0.05) pressed juice percentage values than all ground beef alternatives, indicating the ground beef was juicier than any of the ground beef alternatives evaluated. The Bottom Line: While the ground beef alternative products attempt to mimic ground beef, they provide very different color, texture, tenderness, and cooking characteristics than traditional ground beef

Growing pains in children

We review the clinical manifestations of "growing pains", the most common form of episodic childhood musculoskeletal pain. Physicians should be careful to adhere to clear clinical criteria as described in this review before diagnosing a child with growing pain. We expand on current theories on possible causes of growing pains and describe the management of these pains and the generally good outcome in nearly all children

Consumer Sensory Evaluation of Plant-Based Ground Beef Alternatives in Comparison to Ground Beef of Various Fat Percentages

Objective: The objective of this study was to determine if current plant-based protein ground beef alternatives offer similar palatability characteristics to ground beef patties of varying fat percentages. Study Description: Fifteen different production lots (n = 15/fat level) of 3 lb ground beef chubs of three different fat levels (10%, 20%, and 30%) were collected from retail markets in the Manhattan, KS, area. Additionally, alternative products including a soy and potato protein-based foodservice ground beef alternative, a pea protein-based retail ground beef alternative, and a traditional soy protein-based ground beef alternative, (n = 15 production lots/product) currently available through commercial channels were collected from retail markets and a commercial foodservice chain. All ground beef and alternative treatments were formed into 0.25-lb patties and frozen at -40 degrees F until consumer sensory analysis. Results: All three ground beef samples rated higher (P \u3c 0.05) than the three alternative samples for appearance, overall flavor, beef flavor, and overall liking. Retail alternative rated lowest (P \u3c 0.05) for appearance, overall flavor, texture, and overall liking. Of the alternative samples, foodservice alternative rated highest (P \u3c 0.05) for juiciness, beef flavor, and texture liking, and traditional alternative rated lowest (P \u3c 0.05) for juiciness. However, the foodservice alternative rated higher (P \u3c 0.05) for tenderness than the 20% fat ground beef samples. Moreover, of the alternative samples, the foodservice alternative and traditional alternative rated similar (P \u3e 0.05) for appearance, tenderness, overall flavor liking, and overall liking. Among the ground beef samples, no differences (P \u3e 0.05) were found for appearance, juiciness, overall flavor liking, beef flavor liking, or overall liking. For the percentage of samples rated acceptable for each palatability trait, all three ground beef treatments had a higher (P \u3c 0.05) percentage of samples rated acceptable for appearance, overall flavor liking, beef flavor liking, texture, and overall liking than the three alternative. Retail alternative had the lowest (P \u3c 0.05) percentage of samples rated acceptable for appearance, overall flavor, texture, and overall liking. Traditional alternative had the lowest (P \u3c 0.05) percentage of samples rated acceptable for juiciness. Among the alternative samples, foodservice alternative had the highest (P \u3c 0.05) percentage of samples rated acceptable for juiciness and beef flavor liking. Furthermore, among the alternative treatments, foodservice alternative and traditional alternative had a similar (P \u3e 0.05) percentage of samples rated acceptable for appearance, overall flavor liking, texture liking, and overall liking. The Bottom Line: While the ground beef alternative products attempt to mimic ground beef, they provide very different consumer eating experiences than traditional ground beef

Childhood abdominal pain in primary care: design and patient selection of the HONEUR abdominal pain cohort

Background: Abdominal pain in children is a common complaint presented to the GP. However, the prognosis and prognostic factors of childhood abdominal pain are almost exclusively studied in referred children. This cohort study aims at describing prognosis and prognostic factors of childhood abdominal pain in primary care. In this paper we describe methods used for data-collection and determine possible selective recruitment. Methods/Design: We conducted an observational, prospective cohort study with a 1-year follow-up. From May 2004 to March 2006, 53 Dutch GPs recruited consecutive children aged 4-17 years with a new episode of abdominal pain not preceded by a consultation for this complaint in the previous 3 months. Participants filled in standardized questionnaires, and faeces and urine were sampled. To evaluate selective recruitment, the electronic medical records of participating GPs were retrospectively searched for eligible non-included children. Discussion: This study allows us to describe prognosis and prognostic factors of childhood abdominal pain in primary care. A total of 305 children were included of whom 142 (46.6%) met predefined criteria for chronic/recurrent abdominal pain at presentation; from the total group of eligible children identified from the electronic medical record, 27% were included. The included children were significantly younger than non-included children (mean age 8.49 and 9.20 years). In proportion to identified eligible children, significantly less children diagnosed with "gastroenteritis" (6.8%) and significantly more children with "generalized abdominal pain" (39%) were included compared to the 27% that was expected. This cohort represents young school-aged children consulting GPs for a new episode of abdominal pain, not diagnosed as gastroenteritis. Almost half of them fulfil the criteria for chronic abdominal pain at presentation
