Abstract
Post-weaning diarrhoea (PWD) is a frequent, multifactorial disease of piglets leading to increased mortality rates and high economic losses. Due to the emergence of multi-resistant Escherichia coli isolates and the ban of zinc oxide (ZnO) in the EU since June 2022, alternative measures to prevent PWD are urgently needed. While an abundance of feed supplements is described to prevent PWD, there are hardly any studies reflecting the current situation of PWD in the field. Thus, we aimed to identify differences in management practices, housing and feeding strategies between farms with PWD and farms without PWD. Data were personally collected using a semi-structured questionnaire in 257 Austrian piglet-producing farms. Farms with PWD in more than 10% of all weaned groups within twelve months prior to data collection were defined as case farms (n = 101). Data from 237 farms and 69 explanatory variables were analysed via penalized binary logistic regression using elastic-net in 100 different splits into randomly selected training- and test datasets (80:20). Treatment with ZnO and/or colistin (136 farms) was negatively associated with PWD in all splits and had the biggest estimated absolute log odds ratio out of all tested variables. Implementation of an all-in/all-out system in the nursery units and administration of probiotics or horseradish also had preventative effects in most splits (≥ 97%). A higher number of feeding phases for piglets within the first seven weeks of life and housing on fully slatted floors was associated negatively with the occurrence of PWD as well in > 95% of all splits. PWD was more likely to occur on farms having problems with neonatal diarrhoea or postpartum dysgalactia syndrome. While our data demonstrate that treatment with ZnO or colistin had the biggest statistical effect on PWD, we were able to identify other preventative measures like supplementation with probiotics or horseradish. Since implementation of all-in/all-out measures and fully slatted floors were also negatively associated with the occurrence of PWD on visited farms, we assume that reduction of bacterial load by the implementation of simple hygiene measures are still crucial to prevent PWD.

Authors: Chen Jeng-Tzong , Kao Shing-Kai , Chou Yeng-Ting , Tai Wei-Chen 
Published: September 2022

Abstract
The electrostatics of two cylinders charged to the symmetrical or anti-symmetrical potential is studied by using the null-field boundary integral equation (BIE) in conjunction with the degenerate kernel in terms of bipolar coordinates. The undetermined coefficient is obtained according to the Fredholm alternative theorem. Uniqueness of solution, infinite solution and no solution is therein discussed. A single cylinder case (circle or ellipse) is also provided for comparison. The link to the general solution space is also done. The condition at infinity is also correspondingly examined. The flux equilibrium along the circular boundaries and the infinite boundary is also checked as well as the contribution of the boundary integral (single and double layer potential) along the infinite boundary in the BIE is addressed. The ordinary and degenerate scales in the BIE are both investigated. Solution space limited by the BIE is also explained after comparing with the general solution. Identities between the present result and those in the literature of Darevski and Lekner results in Russia and NewZealand, respectively, is also constructed.

Abstract
The acoustoelastic effect in complex structures is gradually focused by scholars. However, there are no valid methods to characterize and simulate the acoustoelastic effects in complex structures such as ribbed plate structures. Therefore, this paper proposes methods to characterize the acoustoelastic effects in such structures respectively based on wave propagation delay and eigenfrequency, and then develops corresponding simulation methods for acoustoelastic effects of the representative cross-sections of the ribbed plate structure. Finally, the acoustoelastic effects in cross-sections of ribbed plate structures with different fillet radii are characterized based on the Degree of Acoustoelastic Effects (DAEE) defined by wave propagation delay and eigenfrequency respectively, and the related laws of DAEE are summarized.

Abstract
Purpose: During the ongoing COVID-19 global pandemic, there have been treatment gaps for common physical and mental disorders due to vast reasons like lockdowns, poor convenience, fear of getting COVID infection, and economic restraints. Hence, to reduce the treatment gap and, also to limit exposure to COVID-19 infections, telemedicine in the form of telephonic and internet consultations has been increasingly adopted worldwide. Our centre also started telepsychiatry to cater for the needs of patients with pre-existing mental health disorders to ensure regular follow-up and compliance with prescriptions. The study aimed to assess the level of patient satisfaction through online psychiatric services (Telepsychiatry).
Methods: Ethical clearance for the present study was granted by the research cell of the study centre. The sample consisted of 100 patients with pre-existing mental health disorders. This was a single-point cross-sectional study for 6 months. Hospital Information system (HIS) software, which is used to manage the patient's appointment schedule, relevant clinical and lab details along with follow-up prescriptions was used to follow the selected patients for study purposes. This software also provides a digital platform for video calls for online consultation. Client Satisfaction Questionnaires-8 (CSQ-8) were applied to collect patient data for analysis.
Result: The mean total CSQ-8 score of the study sample was 21.01±5.80 (8-32), which indicates a low to moderate level of satisfaction with online psychiatric services. Most patients (45%) reported low satisfaction levels followed by 37% of the patients who reported moderate levels of satisfaction. Only 18% of the patients reported higher satisfaction with online psychiatric services.
Conclusion: Despite the psychiatrist's ability to deliver adequate professional advice and psychoeducation through online psychiatric services, the patient’s level of satisfaction was moderate to low. This suggests a need to design standard protocols and guidelines for consultation through online psychiatric services to enhance the patient’s level of satisfaction.

Published: September 2022

Abstract
Plant litter decomposition is a major nutrient input to terrestrial ecosystems that is primarily driven by microorganisms. Litter decomposition results in a flow of dissolved organic carbon (DOC) that links above-ground decomposition to below-ground microbial processes. Litter decomposition is expected to be altered by human-induced global disturbances—specifically nitrogen deposition and altered intensity and frequency of precipitation events—but little is known about impacts on the mobile pool of DOC. This study investigated the effect of simulated nitrogen deposition and increased precipitation events on microbially-driven carbon flow during short-term litter decomposition using a ‘common garden’ experimental design with microcosms containing sterile sand and blue grama grass litter inoculated with different soil microbial communities. Respiration (CO2) was measured throughout the experiment while microbial biomass carbon and nitrogen were quantified at the end. Overall, nitrogen deposition decoupled CO2 and DOC during short-term litter decomposition with respiration increasing and no affect on DOC concentration. Moreover, nitrogen deposition increased microbial biomass and had no effect on carbon use efficiency (CUE). Simulated precipitation events significantly increased DOC concentrations, decreased CUE, increased the microbial metabolic quotient (qCO2), and greatly altered microbial composition and diversity. These findings highlight the complex interactions and responses of surface litter decomposers to the combined effects of climate change and supports the need for more research into how varying microbiomes will respond to different global change scenarios. Furthermore, this study clearly indicates that any increases in soil carbon sequestration from nitrogen deposition are unlikely to arise from a larger supply of DOC.

Published: September 2022

Abstract
Background
Subscapularis muscle strains can develop in professional baseball players, rendering the players unable to continue playing for a certain period. However, the characteristics of this injury are not well known. The purpose of the present study was to investigate the details of the injury and the post injury course of subscapularis muscle strain in professional baseball players.
Methods
Of 191 players (83 fielders and 108 pitchers) who were members of a single Japanese professional baseball team between January 2013 and August 2022, 8 players (4.2%) had subscapularis muscle strain and were enrolled in this study. The diagnosis of muscle strain was made on the basis of shoulder pain and magnetic resonance imaging findings. The incidence of subscapularis muscle strain, the details of the site of the injury, and the time to return to play were examined.
Results
Subscapularis muscle strain occurred in 3 (3.6%) of 83 fielders and 5 (4.6%) of 108 pitchers, with no significant difference between fielders and pitchers. All players had injuries on the dominant side. Most injuries were located at the myotendinous junction and in the inferior half of the subscapularis muscle. The mean time to return to play was 55.3 ± 40.0 (range, 7-120) days. At a mean 21.0 months after the injury, there were no re-injured players.
Conclusions
Baseball players who have shoulder pain should be regarded as having possible subscapularis muscle strain, and proactive examination should be considered.

Spider mites avoid caterpillar traces to prevent intraguild predation
Authors: Kinto Shiori , Akino Toshiharu , Yano Shuichi 
Published: September 2022

Abstract
The phytophagous spider mites Tetranychus kanzawai and Tetranychus urticae can be as small as <0.5 mm; thus, they are often incidentally consumed along with food plant leaves by voracious lepidopteran larvae (hereafter, ‘caterpillars’). Therefore, the ability to avoid such intraguild predation should confer a selective advantage to mites. We experimentally demonstrated that adult females of both mite species avoided settling on food plant leaves with traces of all tested caterpillar species (Bombyx mori, Papilio xuthus, Spodoptera litura and Theretra oldenlandiae). We examined additional interactions using B. mori and T. kanzawai and found that B. mori trace avoidance by T. kanzawailasted for more than 48 h. Tetranychus kanzawai also avoided B. moritraces on plant stems, along which mites access leaves. Moreover, T. kanzawai avoided acetone extracts of B. mori traces applied to filter paper, indicating that chemical substances of caterpillar traces are responsible for the avoidance. This study is the first demonstration of a repellent effect of herbivore trace chemicals on heterospecific herbivores. Although spider mites have developed resistance against many synthetic pesticides, these results predict that natural compounds simulating caterpillar traces may repel spider mites from agricultural crops.

Abstract
Biometric system is useful to identify person. Biometric systems are rising and generally used technology. Because of this generalization today many protected systems are taking advantage of biometric systems. And one of these newest research areas of biometric systems is gait analysis systems. Numerous locations, including banks, airports, courtrooms for criminal proceedings, and security reasons, require the biometric technology. We can recognize a person by their fingerprints, handprints, eyes (retina), and face with the use of a biometric system . The issue of walking behavior is addressed through the use of gait technology. In security and video surveillance applications, gait identification is crucial. A person's lack of walking style may be resolved by reorganizing the gait. Gait biometric skill recognizes a individual by the walking pattern. Gait study investigates human body parts to find personal features for human recognition. Gait technology recognizes person walking pattern for individual detection. When person identification ratio matches up to 60% to 70% in order to that here Re-identification is solution. Several studies on this study area are examined during the survey.

Published: September 2022

Abstract
Background

Sustained release of bioactive BMP2 (bone morphogenetic protein-2) is badly needed for bone regeneration, while the intrinsic short half-life of BMP2 at protein level cann’t meet the clinical need. In this study, we aimed to design Bmp2 mRNA-enriched engineered exosomes, which were then loaded into specific hydrogel to achieve sustained release for more efficient and safe bone regeneration.

Results

BMP2 mRNA was enriched into exosomes by selective inhibition of translation in donor cells, in which NoBody (non-annotated P-body dissociating polypeptide, a protein that inhibits mRNA translation) and modified engineered Bmp2 plasmids were co-transfected. The derived exosomes were named ExoBMP2+NoBody. In vitro experiments confirmed that ExoBMP2+NoBody had higher abundance of Bmp2 mRNA and thus stronger osteogenic induction capacity. When loaded into GelMA hydrogel via ally-L-glycine modified CP05 linker, the exosomes could be slowly released and thus ensure prolonged effect of BMP2 when endocytosed by the recipient cells. In the in vivo calvarial defect model, ExoBMP2+NoBody-loaded GelMA displayed great capacity in promoting bone regeneration.

Conclusions

the proposed ExoBMP2+NoBody-loaded GelMA can provide an efficient and innovative strategy for bone regeneration.
Identity Influences on Medical Students’ Orientation to Feedback During Rotations
Authors: Thompson Charee M. , Kerr Anna M. 
Published: September 2022

Abstract
Medical students’ attitudes about and preferences for feedback from preceptors may change over the course of the third year of medical school and is likely influenced by identity-related factors. We propose that both how students view themselves personally (i.e., impostor syndrome) and how they view themselves in relation to the group (i.e., identification with the profession) are identity factors related to related to feedback orientation during clinical rotations. 177 third-year medical students enrolled in our four-phase longitudinal survey study beginning at the start of clinical rotations and continuing every twelve weeks of the academic year thereafter. Mixed modeling was utilized to assess models that included phase, sex, and specialty intention as covariates and impostor syndrome and group identity as predictors of feedback orientation. Results indicate that feedback orientation does not significantly change during the third year. Instead, across phases, impostor syndrome was at least marginally, significantly associated with all aspects of feedback orientation across phases—utility, retention, sensitivity, and confidentiality. Group identity was associated with feedback utility and retention, and female-identifying students reported significantly greater feedback confidentiality and feedback retention. Interventions may be needed to improve medical students’ attitudes about feedback, particularly for those who experience impostor syndrome. Fostering group cohesion among medical students may influence how well students remember feedback and find it useful.
Field monitoring and analysis of the stress variation relationship between fiberglass bolts and face deformation in tunnels based on the ADECO-RS construction approach

Published: September 2022

Abstract
One of the main causes for excessive deformation within a tunnel is due to the instability of the soil or soft rock ahead of the excavation face. Fiberglass bolts have been shown to be a useful advance reinforcement method for the excavation face. In this paper, an improved ADECO-RS (Analysis of controlled deformation in rock and soils) method have been proposed for soft rock mountain tunnels, in terms of the partial (mainly the upper bench) excavation face reinforcement and also for the bench excavation method. Strain gauges were used to test the micro-strain in the fiberglass bolt to investigate how the axial force of the fiberglass bolt varied during the tunnel excavation. In addition, combined with the field tunnel deformation monitoring data, the relationship between the reinforcement parameters of the fiberglass bolts and the tunnel construction phase has been discussed. The conclusions of this study are: (1) The redistribution of the stress after the excavation led to an increase in the stresses of the surrounding rock near the excavation face, and there was a significant stress increase in the fiberglass bolt; (2) The excavation during the lap area of the fiberglass bolt led to an increase in the axial force in the bolt, however, the excavation outside the lap area of the fiberglass bolt didn’t show any influence on the bolt; (3) The deformation of the tunnel met the construction specification by ensuring the stability of the excavation face and closing the loop of each initial support construction as soon as possible; (4) In a future project with similar conditions, the recommended lap length of the fiberglass bolt was 3 m utilizing the fiberglass bolt grouting face reinforcement method.

Published: September 2022

Abstract
Background and Purpose
The clinical role of postoperative adjuvant therapy in hepatocellular carcinoma (HCC) is still unclear. The purpose of our study was to explore the clinical value of postoperative adjuvant anti-programed cell death 1 antibody (PA-PD-1) on the prognosis of HCC patients with high relapse risks after surgery.
Patients and Methods
Consecutive HCC patients with high recurrence risks treated with liver resection at our center during January 2019 and March 2021 were prospectively enrolled. Baseline differences were balanced between HCC patients with (PA-PD-1 group) or without PA-PD-1 (non-PD-1 group) after hepatectomy by propensity-score matching (PSM). Between these two groups, we compared overall survival (OS) and recurrence-free survival (RFS). Independent prognostic risk factors for OS and RFS were confirmed by Cox regression analysis and subgroup analysis was also performed.
Results
47 pairs of patients with or without PD-1 treatment after hepatectomy were matched. After PSM, the 1-year and 2-year RFS were 58.4% and 44.1% in the PA-PD-1 group, and 34.0% and 21.3% in the non-PD-1 group (p = 0.008). The OS at 1-year and 2-year were 91.2% and 91.2% in the PA-PD-1 group, compared with 85.1% and 61.7% in the non-PD-1 group (p= 0.024). Multivariable analyses demonstrated that PA-PD-1 was an independent protective predictor associated with RFS and OS. Through subgroup analysis, we concluded that HCC patients with portal venous tumor thrombus (PVTT) or tumor size ≥ 5 cm significantly benefited from PA-PD-1 therapy in RFS and OS.
Conclusions
Adjuvant anti-PD-1 antibody can effectively improve the survival outcomes of HCC patients with high relapse risks after hepatectomy.

Abstract
Background. Two procedures are available to obtain prenatal information: invasive diagnostic procedures, and non-invasive diagnostic procedures, such as those that use cell-free fetal DNA. Several psychological factors are involved in the decision to undergo a non-invasive prenatal testing (NIPT) but little is known about the decision-making strategies involved in choosing a specific level of in-depth NIPT, considering the increased availability and complexity of NIPT options. The main aim of this work is to assess the impact of psychological factors (anxiety about pregnancy, perception of risk in pregnancy, intolerance to uncertainty), and COVID-19 pandemic on the type of NIPT chosen, in terms of the number of conditions that are tested.
Methods. A self-administered survey evaluated the decision-making process about NIPT. The final sample comprised 191 women (Mage= 35.53; SD= 4.79) who underwent a NIPT from one private Italian genetic company. Based on the test date, the sample of women was divided between “NIPT before COVID-19” and “NIPT during COVID-19”.
Results. Almost all of the participants reported being aware of the existence of different types of NIPT and more than half reported having been informed by their gynecologist. Results showed no significant association between the period in which women underwent NIPT (before COVID-19 or during COVID-19) and the preferences for more expanded screening panel. Furthermore, regarding psychological variables, results showed a significant difference between baby’s risk perception based on the NIPT type groups, revealing that the mums-to-be who underwent the more expanded panel had a significantly higher level of baby’s risk perception than that reported by the mums-to-be who underwent the basic one. There was no statistically significant difference between the other psychological variables and NIPT type.
Conclusions. Our findings indicate the paramount role of gynecologist and other health care providers, such as geneticists and psychologists, to support decision-making process in NIPT, in order to overcome people’s deficits in genetic knowledge, promote awareness about their preferences, and control anxiety related to the unborn child. Decision-support strategies are critical during the onset of prenatal care, according to the advances in prenatal genomics and to parent’s needs.
