Published: February 2023

AbstractThe SiCnws/SiC nanocomposites were in situ synthesized by using nickel carbon foam as catalyst and skeleton. This technique has a series of advantages including simple operation, low cost, and high efficiency. Due to the excellent microwave absorption and thermal properties of SiCnws, SiCnws/SiC nanocomposites possess excellent electromagnetic shielding performance with a high SET value of 38.3 dB and good thermal properties with thermal conductivity of 13.77 ± 0.098 wm−1k−1 at room temperature. Meanwhile, the bending strength of the nanocomposites is 110.9 ± 7.7 MPa. The friction coefficient of nanocomposites is about 0.26 with a wear speed of about 67 um3/s. Therefore, the nanocomposites integrate many advantages including lightweight (2.0 g/cm3), excellent electromagnetic shielding, good heat conduction, high strength, and wear resistance.

AbstractBackgroundOlder surgical patients have an increased risk for postoperative complications, driving up healthcare costs. We determined if postoperative co‐management of older surgery patients is associated with postoperative outcomes and hospital costs.MethodsRetrospective data were collected for patients ≥70 years old undergoing colorectal surgery at a community teaching hospital. Patient outcomes were compared between those receiving postoperative surgery co‐management care through the Optimization of Senior Care and Recovery (OSCAR) program and controls who received standard of care. Main outcome measures were postoperative complications and hospital charges, 30‐day readmission rate, length of stay (LOS), and transfer to intensive care during hospitalization. Multivariable linear regression was used to model total charge and multivariable logistic regression to model complications, adjusted for multiple variables (e.g., age, sex, race, body mass index, Charlson Comorbidity Index [CCI], American Society of Anesthesiologists score, surgery duration).ResultsAll 187 patients in the OSCAR and control groups had a similar mean CCI score of 2.7 (p = 0.95). Compared to the control group, OSCAR recipients experienced less postoperative delirium (17% vs. 8%; p = 0.05), cardiac arrhythmia (12% vs. 3%; p = 0.03), and clinical worsening requiring transfer to intensive care (20% vs. 6%; p < 0.005). OSCAR group patients had a shorter mean LOS among high‐risk patients (CCI ≥3) (−1.8 days; p = 0.09) and those ≥80 years old (−2.3 days; p = 0.07) compared to the control group. Mean total hospital charge was $10,297 less per patient in the OSCAR group (p = 0.01), with $17,832 less per patient with CCI ≥3 (p = 0.01), than the control group.ConclusionsA co‐management care approach after colorectal surgery in older patients improves outcomes and decreases costs, with the most benefit going to the oldest patients and those with higher comorbidity scores.

AbstractBackgroundHearing impairment is common among older adults and affects cognitive assessments for identification of dementia which rely on good hearing function. We developed and validated a version of the Montreal Cognitive Assessment (MoCA) for people with hearing impairment.MethodsWe adapted existing MoCA 8.1 items for people with hearing impairment by presenting instructions and stimuli in written rather than spoken format. One Attention domain and two Language domain items required substitution by alternative items. Three and four candidate items respectively were constructed and field‐tested along with the items adapted to written form. We used a combination of individual item analysis and item substitution to select the set of alternative items to be included in the final form of the MoCA‐H in place of the excluded original items. We then evaluated the performance and reliability of the final tool, including making any required adjustments for demographic factors.ResultsOne hundred and fifty‐nine hearing‐impaired participants, including 76 with normal cognition and 83 with dementia, completed the adapted version of the MoCA. A further 97 participants with normal hearing completed the standard MoCA as well as the novel items developed for the MoCA‐H to assess score equivalence between the existing and alternative MoCA items and for independence from hearing impairment. Twenty‐eight participants were retested between 2–4 weeks after initial testing. After the selection of optimal item set, the final MoCA‐H had an area under the curve of 0.973 (95% CI 0.952–0.994). At a cut‐point of 24 points or less sensitivity and specificity for dementia was 92.8% and 90.8%, respectively. The intraclass correlation for test–retest reliability was 0.92 (95%CI 0.78–0.97).ConclusionThe MoCA‐H is a sensitive and reliable means of identifying dementia among adults with acquired hearing impairment.

AbstractAdequate nutritional intake in the first years of life is crucial for future health. The purpose of this study is to assess the adequacy of nutritional intake in Portuguese toddlers. The EPACI Portugal 2012 is a cross‐sectional study of a representative sample of toddlers (n = 2230), aged between 12 and 36 months. Data on diets were collected by trained interviewers. The current analysis included 853 children with full data from 3‐day food diaries completed by parents/caregivers. Intakes of energy, macro‐ and micronutrients were estimated through Statistical Program to Assess Dietary Exposure (SPADE). Nutritional adequacy was evaluated using Dietary Reference Values established by the European Food Safety Authority. A large proportion of children exceeded the recommended energy intake. The median daily protein intake was 4.7 g/kg/day, five times more than that recommended. About 9% and 90% of the children consumed a lower proportion of energy than the lower limit of the Reference Intake range for carbohydrates and fat, respectively. Around a third consumed less fibre and magnesium and 100% less vitamin D than the recommended Adequate Intake (AI). Almost a third consumed less vitamin A than the recommended Average Requirement (AR) and 86% of the children showed excessive sodium consumption. Portuguese toddlers consumed a low proportion of energy from fat, had energy and protein intakes above the recommendations and excessive intakes of sodium, and inadequate intakes of vitamin A. Every child consumed less than the recommended AI for vitamin D.

ObjectiveWear particles induce inflammation and the further osteolysis around the prosthesis, has been proven to be the main cause of aseptic hip joint loosening. In this research, we aimed to clarify whether human umbilical cord mesenchymal stem cells (HUCMSCs) could inhibit the titanium particles‐induced osteolysis and shed light upon its mechanism.MethodsThe expression of chemokine (C‐C motif) ligand 2 (CCL2), chemokine (C‐C motif) ligand 3 (CCL3) and chemokine (C‐C motif) ligand 5 (CCL5) were examinjed in clinical specimens of aseptic hip prosthesis loosening patients. Local injection of lentivirus that knocked down CCL2 or CCL3 in a cranial osteolysis mice model were used to exam the effect of CCL2 and CCL3 on titanium particles‐induced osteolysis in vivo. Transwell assay was used to examine the effect of CCL2 and CCL3 on titanium particles‐induced activation of macrophage in vitro. Furthermore, the therapeutic effect of HUCMSCs, and exosomes from HUCMSCs were also examed in vivo and vitro. Immunohistochemical and real‐time PCR were used to examine the expression of relative pathways. Analysis of variance (ANOVA) and Student–Newman–Keuls post hoc t test were used to analyze the results and determine the statistical significance of the differences.ResultsResults showed that titanium particles caused the osteolysis at the mice cranial in vivo and a large number of macrophages that migrated, while local injection of HUCMSCs and exosomes did inhibit the cranial osteolysis and migration. An exosome inhibitor GW4869 significantly increased the osteolysis area in the mice cranium osteolysis model, and increased the number of migrated macrophages. Immunohistochemical results suggested that the expression of CCL2, CCL3 and CD68 in the cranial in Titanium particles mice increased significantly, but was significantly reduced by HUCMSCs or exosomes. HUCMSC and exosomes down‐regulate the expression of CCL3 in vitro and in vivo.ConclusionHUCMSCs and HUCMSC‐derived exosomes could suppress the titanium particles‐induced osteolysis in mice through inhibiting chemokine (C‐C motif) ligand 2, chemokine (C‐C motif) ligand 3.
Distinguishing annular pustular psoriasis from subcorneal pustular dermatosis—A diagnostic dilemma in a 10‐year‐old boy
Authors: Masison Joseph , Adalsteinsson Jonas A. , Chang Mary Wu 
Published: February 2023

AbstractSubcorneal pustular dermatosis (SPD) and annular pustular psoriasis (APP) are very rare in childhood and difficult to differentiate both clinically and histopathologically. We report the case of a 10‐year‐old male with a 9‐year history of erythematous scaly annular plaques with scattered pustules on the trunk. Although initially diagnosed as SPD, a lack of response to dapsone, presence of spongiosis on histology, and early age of disease onset led to consideration of APP. The patient was subsequently treated with adalimumab 80 mg weekly and completely cleared. This case illustrates the overlapping features of SPD and APP and suggests that the two disorders may represent a spectrum of the same disease.

AbstractWheat yellow rust (YR) is a most devastating disease in wheat worldwide. In recent years, the epidemic in China has expanded from traditional areas to the middle and lower reaches of the Yangtze River due to the changes in climate and cropping systems. To facilitate YR resistance breeding, it is meaningful to explore resistance loci from local germplasm resources. In this study, a linkage mapping was performed in a recombinant inbred line (RIL) population derived from Ningmai 9 × Yangmai 158 using a high‐density genetic map and phenotypic identification for adult plant resistance (APR) to YR in four environments. Phenotypic analysis showed that Yangmai 158 had better APR than Ningmai 9. Disease severity in different environments was significantly correlated with each other, and it was found that disease severity was significantly influenced by genotype, environment and their interaction. A total of 19 quantitative trait loci (QTLs) were identified, of which four could be detected in multiple environments and four corresponding KASP markers were then developed. Lines with different QTLs from the population including 476 chromosome segment substitution lines (CSSLs) were evaluated for APR. The results revealed that Qyr‐4B.4 and Qyr‐5B.2 could significantly reduce the disease severity, with their combination showing a better effect. The findings of the study can be beneficial for wheat YR resistance breeding in the middle and lower reaches of the Yangtze River.
Techniques on vertical ridge augmentation: Indications and effectiveness
Authors: Urban Istvan A. , Montero Eduardo , Amerio Ettore , Palombo David , Monje Alberto 
Published: February 2023

AbstractVertical ridge augmentation techniques have been advocated to enable restoring function and esthetics by means of implant‐supported rehabilitation. There are three major modalities. The first is guided bone regeneration, based on the principle of compartmentalization by means of using a barrier membrane, which has been demonstrated to be technically demanding with regard to soft tissue management. This requisite is also applicable in the case of the second modality of bone block grafts. Nonetheless, space creation and maintenance are provided by the solid nature of the graft. The third modality of distraction osteogenesis is also a valid and faster approach. Nonetheless, owing to this technique's inherent shortcomings, this method is currently deprecated. The purpose of this review is to shed light on the state‐of‐the‐art of the different modalities described for vertical ridge augmentation, including the indications, the step‐by‐step approach, and the effectiveness.

Published: February 2023

AbstractBackgroundThis study sought to investigate the frequency and characteristics of duplicate prescriptions (DPs) in elderly psychiatric inpatients using a novel categorisation of DPs that differentiates between appropriate duplicate prescriptions (ADPs) and potentially inappropriate duplicate prescriptions (PIDPs).MethodsThe study was conducted as a monocentric retrospective cross‐sectional pilot study on the gerontopsychiatric ward of the Department of Psychiatry, Social Psychiatry and Psychotherapy of Hannover Medical School, a large university hospital in northern Germany. The outcome measures were the nature and frequency of PIDPs compared with the frequency of ADPs.ResultsFor 92 individual patients a total of 339 medication chart reviews were conducted between April 2021 and February 2022. The median age of the study population was 73 years (interquartile range (IQR) 68–82 years); 64.6% were female. Patients' medications comprised a median of eight drugs (IQR 6–11 drugs) and 43.1% of the study population were exposed to at least one PIDP (at least one grade‐1 PIDP: 39.5%; at least one grade‐2 PIDP: 5.0%; at least one grade‐3 PIDP: 1.5%). Sedatives were most frequently responsible for grade‐1 and grade‐2 PIDPs, while grade‐3 PIDPs were elicited exclusively by analgesics. Nearly half of the study population (49.0%) displayed at least one ADP.ConclusionEven though the clinical implications of PIDPs are not fully established to date, we recommend that physicians who treat elderly psychiatric patients pay special attention to PIDPs, especially PIDPs elicited by sedatives. Termination of PIDPs may prevent adverse drug reactions and save healthcare expenditures.
An Evolutionary Approach of Grasp Synthesis for Sheet Metal Parts With Multitype Grippers
Authors: Tribaldos Jicmat Ali , Sen Chiradeep 
Published: February 2023

AbstractRobot-mounted grippers are used to position, immobilize, and manipulate parts and assemblies during manufacturing. In the design of these systems, the gripper assembly, comprising the grippers that grasp the part and the frame that holds them together, is customized to each part. Due to the large number of design variables and unique design needs for each gripper, automation of gripper assemblies has been limited, especially where multiple gripper types are used to grasp a part. To this end, this article presents an evolutionary approach that synthesizes and optimizes grasps and gripper assembly layouts using two different gripper types—suction cups and magnets—from the geometric models of sheet metal parts. The method first generates an option space of gripper placement on the suitable faces of the part model. Then, a genetic algorithm generates grasps on this option space by varying both the count and locations of each gripper type. Through generations, these grasps are optimized against five criteria and one constraint: factor of safety, cost, residual moment, deflection, frame weight, and gripper clearance. These criteria are then combined into a single criterion that represents a pareto condition for assessing the grasps. The algorithm is implemented in software code for validation, and the article presents detailed validation of the algorithm using four sheet metal parts. The results show that the algorithm improves the grasp from all six aspects, when started from either program-assigned or user-defined initial grasps. The high agreement between the final grasp designs resulting from multiple runs of the algorithm on a part illustrates the stability and repeatability of the algorithm.
Manufacturing Process Classification Based on Distance Rotationally Invariant Convolutions
Authors: Wang Zhichao , Rosen David 
Published: February 2023

Abstract
Given a part design, the task of manufacturing process classification identifies an appropriate manufacturing process to fabricate it. Our previous research proposed a large dataset for manufacturing process classification and achieved accurate classification results based on a combination of a convolutional neural network (CNN) and the heat kernel signature for triangle meshes. In this paper, we constructed a classification method based on rotation invariant shape descriptors and a neural network, and it achieved better accuracy than all previous methods. This method uses a point cloud part representation, in contrast to the triangle mesh representation used in our previous work. The first step extracted rotation invariant features consisting of a set of distances between points in the point cloud. Then, the extracted shape descriptors were fed into a CNN for the classification of manufacturing processes. In addition, we provide two visualization methods for interpreting the intermediate layers of the neural network. Last, the performance of the method was tested on some ambiguous examples and their performances were consistent with expectations. In this paper, we have considered only shape information, while non-shape information like materials and tolerances were ignored. Additionally, only parts that require one manufacturing process were considered in this research. Our work demonstrates that part shape attributes alone are adequate for discriminating between different manufacturing processes considered.

ObjectivesResearch evidence is commonly compiled into expert-informed consensus guidelines intended to consolidate and distribute sports medicine knowledge. Between 2003 and 2018, 27 International Olympic Committee (IOC) consensus statements were produced. This study explored the policy and practice impact of the IOC Statements on athlete health and medical team management in two economically and contextually diverse countries.MethodsA qualitative case study design was adopted. Fourteen face-to-face interviews were conducted with purposively selected interviewees, seven participants from Australia (higher economic equality) and seven from South Africa (lower economic equality), representing their national medical commissions (doctors and physiotherapists of Olympic, Paralympic and Youth teams). A framework method was used to analyse interview transcripts and identify key themes.ResultsDifferences across resource settings were found, particularly in the perceived usefulness of the IOC Statements and their accessibility. Both settings were unsure about the purpose of the IOC Statements and their intended audience. However, both valued the existence of evidence-informed guidelines. In the Australian setting, there was less reliance on the resources developed by the IOC, preferring to use locally contextualised documents that are readily available.ConclusionThe IOC Statements are valuable evidence-informed resources that support translation of knowledge into clinical sports medicine practice. However, to be fully effective, they must be perceived as useful and relevant and should reach their target audiences with ready access. This study showed different contexts require different resources, levels of support and dissemination approaches. Future development and dissemination of IOC Statements should consider the perspectives and the diversity of contexts they are intended for.
