AbstractBackgroundThe origin of different human emotions directed towards animals (whether in the utilitarian, affective, conflictual, or cosmological context) is strongly influenced by sociocultural factors, although our genetic predispositions also play an important role in the origin of these emotions. Such emotions guide people’s representations of different species, which in turn affect their attitudes toward them. For this reason, understanding the factors that guide such attitudes becomes a key element in making conservationist decisions. In this sense, the main objective of this study was to analyze how sociocultural characteristics and bioecological representations can influence students’ attitudes of empathy or antipathy towards vertebrate species; as well as which classes and species are related to greater and lesser support in people for their conservation.MethodsTo do so, 667 interviews were conducted with students from urban (n = 1) and rural (n = 2) schools in the Brazilian semi-arid region. We used mixed generalized linear models (GLMM) to examine the effect of social factors and bioecological representations on empathy and antipathy attitudes and multiple factor analysis (MFA) to examine the relationship between the biological characteristics of the animals (positive or negative) and the attitudes toward them (antipathetic or empathetic).ResultsThrough GLMM, we found that students from the urban area and from lower school levels are more extreme in their responses, more frequently expressing both empathy and antipathy towards wild animals. Regarding gender, women had a higher frequency of responses associated with aversion than men for species perceived as dangerous and poisonous (p < 0.001). Through the MFA, we found greater support (empathy) for the conservation of fish species (31.56%), birds (29.37%) and mammals (25.94%), with emphasis on the Red-cowled cardinal (Paroaria dominicana) and clownfish (Amphiprion ocellaris) species, and less support (antipathy) for reptile and amphibian species such as rattlesnakes (Crotalus durissus) and horned frogs (Ceratophrys joazeirensis).ConclusionsThe attitudinal ambivalence reflected by varying empathy for certain species and antipathy to others has important implications for wildlife conservation. Understanding the socioeconomic factors and emotions that influence attitudes towards animals can enable integrating educational strategies for the conservation of species, especially those which are culturally important.
Expansion of India’s national child healthcare programme, Rashtriya Bal Swasthya Karyakram (RBSK), for rare disease management : a health policy perspective

Published: June 2023

AbstractRare diseases (RD) are severe and debilitating conditions. They are one of the leading causes of childhood mortality globally. In India, RDs have not been considered in most healthcare programs which usually cater to more common diseases. We believe, that for efficient utilization of resources in a resource-constrained healthcare system, existing programs must integrate RD management strategies. In this study, we explore the utility, expandability, and limitation of one of the important national child healthcare programs, Rashtriya Bal Swasthya Karyakram (RBSK) which translates to National Child Healthcare Program. We found that RBSK has immense potential to cater to RDs through some of its unique features, such as comprehensive screening, wide target age group, and efficient utilization of resources. We provide recommendations that can help to strengthen the present program. This study will inspire other low-resource countries to identify and expand existing public healthcare programs for RD management. Moreover, RBSK can serve as a model program to integrate RD management globally.

Abstract
Background
Xentuzumab is a humanised monoclonal antibody that binds to IGF-1 and IGF-2, neutralising their proliferative activity and restoring inhibition of AKT by everolimus. This study evaluated the addition of xentuzumab to everolimus and exemestane in patients with advanced breast cancer with non-visceral disease.

Methods
This double-blind, randomised, Phase II study was undertaken in female patients with hormone-receptor (HR)-positive/human epidermal growth factor 2 (HER2)-negative advanced breast cancer with non-visceral disease who had received prior endocrine therapy with or without CDK4/6 inhibitors. Patients received a weekly intravenous infusion of xentuzumab (1000 mg) or placebo in combination with everolimus (10 mg/day orally) and exemestane (25 mg/day orally). The primary endpoint was progression-free survival (PFS) per independent review.

Results
A total of 103 patients were randomised and 101 were treated (n = 50 in the xentuzumab arm and n = 51 in the placebo arm). The trial was unblinded early due to high rates of discordance between independent and investigator assessment of PFS. Per independent assessment, median PFS was 12.7 (95% CI 6.8–29.3) months with xentuzumab and 11.0 (7.7–19.5) months with placebo (hazard ratio 1.19; 95% CI 0.55–2.59; p = 0.6534). Per investigator assessment, median PFS was 7.4 (6.8–9.7) months with xentuzumab and 9.2 (5.6–14.4) months with placebo (hazard ratio 1.23; 95% CI 0.69–2.20; p = 0.4800). Tolerability was similar between the arms, with diarrhoea (33.3–56.0%), fatigue (33.3–44.0%) and headache (21.6–40.0%) being the most common treatment-emergent adverse events. The incidence of grade ≥ 3 hyperglycaemia was similar between the xentuzumab (2.0%) and placebo (5.9%) arms.

Conclusions
While this study demonstrated that xentuzumab could be safely combined with everolimus and exemestane in patients with HR-positive/HER2-negative advanced breast cancer with non-visceral disease, there was no PFS benefit with the addition of xentuzumab.

Authors: Luan Hengfei , Hao Conghui , Li Han , Zhang Xiaobao , Zhao Zhibin , Zhu Pin 
Published: June 2023

Abstract
Background
Dexmedetomidine, a potent and highly selective α2-adrenoreceptor agonist has become a popular adjuvant to local anesthetics. The study was designed to explore the effect of dexmedetomidine added to ropivacaine for interscalene brachial plexus block (IBPB) on postoperative analgesia in patients undergoing arthroscopic shoulder surgery.

Methods
Forty-four adult patients undergoing arthroscopic shoulder surgery were randomly divided into 2 groups. Group R received 0.25% ropivacaine alone, whereas group RD received 0.25% ropivacaine and 0.5 μg/kg dexmedetomidine. A total volume of 15 ml was administered for ultrasound-guided IBPB in both groups. Duration of analgesia, visual analog scale (VAS) pain score, frequency of PCA pressed, first time of PCA pressed, sufentanil consumption, and patient satisfaction with analgesia quality were recorded.

Results
Compared with group R, the duration of analgesia was prolonged (8.25±1.76 vs. 11.55±2.41 h; P<0.05), the VAS pain scores were decreased at 8 and 10 h postoperatively (3 (2–3) vs. 0 (0–0) and 2 (2–3) vs. 0 (0–2.25), respectively; P<0.05), the frequencies of PCA pressed were decreased at 4–8 and 8–12 h time intervals (0 (0–0.25) vs. 0 (0–0) and 5 (1.75–6) vs. 0 (0–2), respectively; P<0.05), the time of first PCA pressed was prolonged (9.27±1.85 vs. 12.98±2.35 h; P<0.05), the total 24h sufentanil consumption was reduced (108.72±15.92 vs. 94.65±12.47 μg; P<0.05 ) and patient satisfaction score was also improved (3 (3–4) vs. 4 (4–5); P<0.05) in group RD.

Conclusion
We concluded that adding 0.5 μg/kg dexmedetomidine to 0.25% ropivacaine for IBPB provided better postoperative analgesia, decreased the sufentanil consumption and improved the patient’s satisfaction in patients undergoing arthroscopic shoulder surgery.

Abstract
Background
Polygenic risk score (PRS) analysis is used to predict disease risk. Although PRS has been shown to have great potential in improving clinical care, PRS accuracy assessment has been mainly focused on European ancestry. This study aimed to develop an accurate genetic risk score for knee osteoarthritis (OA) using a multi-population PRS and leveraging a multi-trait PRS in the Japanese population.

Methods
We calculated PRS using PRS-CS-auto, derived from genome-wide association study (GWAS) summary statistics for knee OA in the Japanese population (same ancestry) and multi-population. We further identified risk factor traits for which PRS could predict knee OA and subsequently developed an integrated PRS based on multi-trait analysis of GWAS (MTAG), including genetically correlated risk traits. PRS performance was evaluated in participants of the Nagahama cohort study who underwent radiographic evaluation of the knees (n = 3,279). PRSs were incorporated into knee OA integrated risk models along with clinical risk factors.

Results
A total of 2,852 genotyped individuals were included in the PRS analysis. The PRS based on Japanese knee OA GWAS was not associated with knee OA (p = 0.228). In contrast, PRS based on multi-population knee OA GWAS showed a significant association with knee OA (p = 6.7 × 10−5, odds ratio (OR) per standard deviation = 1.19), whereas PRS based on MTAG of multi-population knee OA, along with risk factor traits such as body mass index GWAS, displayed an even stronger association with knee OA (p = 5.4 × 10−7, OR = 1.24). Incorporating this PRS into traditional risk factors improved the predictive ability of knee OA (area under the curve, 74.4% to 74.7%; p = 0.029).

Conclusions
This study showed that multi-trait PRS based on MTAG, combined with traditional risk factors, and using large sample size multi-population GWAS, significantly improved predictive accuracy for knee OA in the Japanese population, even when the sample size of GWAS of the same ancestry was small. To the best of our knowledge, this is the first study to show a statistically significant association between the PRS and knee OA in a non-European population.

Authors: Luo Huiyan , Chen Jixin , Jiang Qiyin , Yu Yifan , Yang Miaolun , Luo Yuehua , Wang Xiongwen 
Published: June 2023

Abstract
Background & aims
The effects of SARS-CoV-2 infection can be more complex and severe in patients with hepatocellular carcinoma (HCC) as compared to other cancers. This is due to several factors, including pre-existing conditions such as viral hepatitis and cirrhosis, which are commonly associated with HCC.

Methods
We conducted an analysis of epigenomics in SARS-CoV-2 infection and HCC patients, and identified common pathogenic mechanisms using weighted gene co-expression network analysis (WGCNA) and other analyses. Hub genes were identified and analyzed using LASSO regression. Additionally, drug candidates and their binding modes to key macromolecular targets of COVID-19 were identified using molecular docking.

Results
The epigenomic analysis of the relationship between SARS-CoV-2 infection and HCC patients revealed that the co-pathogenesis was closely linked to immune response, particularly T cell differentiation, regulation of T cell activation and monocyte differentiation. Further analysis indicated that CD4+ T cells and monocytes play essential roles in the immunoreaction triggered by both conditions. The expression levels of hub genes MYLK2, FAM83D, STC2, CCDC112, EPHX4 and MMP1 were strongly correlated with SARS-CoV-2 infection and the prognosis of HCC patients. In our study, mefloquine and thioridazine were identified as potential therapeutic agents for COVID-19 in combined with HCC.

Conclusions
In this research, we conducted an epigenomics analysis to identify common pathogenetic processes between SARS-CoV-2 infection and HCC patients, providing new insights into the pathogenesis and treatment of HCC patients infected with SARS-CoV-2.
Learning through clinical extramural studies: an observational study
Authors: Cashman Diane , Rackard Sue 
Published: June 2023

Abstract
Background
Veterinary medicine programmes require students to learn in formal educational settings and through workplace experiences. Previous studies have indicated that learning in the clinical workplace can be informal as students participate in daily activities of service provision by veterinary teams. It can be complex however for students to transition from a traditional formal educational setting to learning in the workplace and students must be able to self-regulate their learning. This requires students to set their own learning goals, consider available learning opportunities and to evaluate if intended learning outcomes have been attained. There is a need to identify strategies students undertake to self-regulate their learning in the workplace to design supports to enhance their learning. The aim of this study was to provide a detailed description of how final year veterinary medicine students plan, learn and reflect on their learning in the workplace context of clinical extramural studies (CEMS) prior to the COVID-19 pandemic.

Methods
An observational repeated cross-sectional design study was conducted with two groups of final year veterinary medicine students in University College Dublin. Data was collected in two stages by analysing student activity records and surveying students in 2017 and 2018. Participants were asked to describe how they planned their CEMS, to describe the types of learning activities they participated in, and describe their reflections of CEMS.

Results
The results are interpreted through the lens of self-regulated learning theory. Analyses of student CEMS activity records indicate that students from both groups primarily participated in small animal / production animal or mixed practice work placements. The majority of respondents of the survey indicated that CEMS was a valuable learning opportunity and they were motivated by placements that would support their future career goals. Financing CEMS placements was a key obstacle to their planning. The majority of respondents indicated varying frequencies of engaging in different types of learning activities and noted that finding suitable placements that facilitated practical skill development and active student learning was a challenge. Implications for veterinary education are discussed.

Conclusions
Student perspectives on planning and learning in the CEMS workplace context yielded important insights into the factors that influence their self-regulatory activities which can help inform future educational interventions to support student learning.
Encapsulated peracetic acid as a valid broad-spectrum antimicrobial alternative, leading to beneficial microbiota compositional changes and enhanced performance in broiler chickens
Authors: Galgano Salvatore , Conway Leah , Dalby Nikki , Fellows Adrian , Houdijk Jos G. M. 
Published: June 2023

AbstractBackgroundAntimicrobial alternatives are urgently needed, including for poultry production systems. In this study, we tested the potential broad-range antimicrobial alternative peracetic acid, delivered in feed via the hydrolysis of encapsulated precursors through a 28-day study using 375 Ross 308 broiler chickens. We tested two peracetic acid concentrations, 30 and 80 mg/kg on birds housed on re-used litter, and we evaluated the impact of both levels on gut microbial communities, bacterial concentration, antimicrobial resistance genes relative abundance and growth performance when compared to control birds housed on either clean or re-used litter.ResultsBody weight gain and feed conversion ratio improved in peracetic acid fed birds. At d 28, birds given 30 mg/kg of peracetic acid had a decreased Firmicutes and an increased Proteobacteria abundance in the jejunum, accompanied by an increase inBacillus,FlavonifractorandRombustiain the caeca, and a decreased abundance of tetracycline resistance genes. Chicken given 80 mg/kg of peracetic acid had greater caecal abundance of macrolides lincosamides and streptogramins resistance genes. Growth performance on clean litter was reduced compared to re-used litter, which concurred with increased caecal abundance ofBlautia, decreased caecal abundance ofEscherichia/Shigella, AnaerostipesandJeotgalicoccus, and greater gene abundance of vancomycin, tetracycline, and macrolides resistance genes.ConclusionsPeracetic acid could be used as a safe broad-spectrum antimicrobial alternative in broilers. Encapsulated precursors were able to reduce the bacterial concentration in the jejunum whilst promoting the proliferation of probiotic genera in the caeca, especially at the low peracetic acid concentrations tested, and improve growth performance. Moreover, our findings offer further insights on potential benefits of rearing birds on re-used litter, suggesting that the latter could be associated with better performance and reduced antimicrobial resistance risk compared to clean litter rearing.

Abstract
Background
Hedera nepalensis is a traditional medicinal plants, and the dried leaves of it are generally used for the cure and treatment of many diseases, also widely known as Chang-Chun-Teng in Chinese. Until now, structural characterization of water-soluble polysaccharides isolated from leaves of Hedera nepalensis have been scarcely studied, even though the chemical compounds derived from it and their biological activities have been widely studied.

Methods
Water-soluble polysaccharides (WHNP) were isolated from the dried leaves of Hedera nepalensis, and their structural features were investigated. One neutral polysaccharide fraction (WHNP-N) and three major pectin fractions (WHNP-A2b, WHNP-A2c and WHNP-A3b) were obtained from WHNP, respectively. There was no analysis of the neutral fraction (WHNP-N), while the structural characterization of three major pectin fractions (WHNP-A2b, WHNP-A2c and WHNP-A3b) were further studied by monosaccharide composition, HPGPC, NMR and methylation analyses.

Results
The results indicated that two fractions WHNP-A2b (Mw = 45.8 kDa) and WHNP-A3b (Mw = 58.6 kDa) were mainly composed of rhamnogalacturonan I (RG-I). In WHNP-A2b, RG-I domains primarily substituted with α-L-1,5/1,3,5-arabinan, type II arabinogalactan (AG-II), β-D-1,4-galactan and/or type I arabinogalactan (AG-I) as side chains, while RG-I-type pectin of WHNP-A3b mainly branched with α-L-1,5/1,3,5-arabinan, β-D-1,4-galactan and AG-II side chains. WHNP-A2c (Mw = 12.4 kDa) was primarily comprised of galacturonic acid (GalA, 60.8%), and enzymatic analysis indicated that this fraction mainly consisted of rhamnogalacturonan I (RG-I), rhamnogalacturonan II (RG-II) and homogalacturonan (HG) domains with mass ratios of 1.8:1.0:0.6. On the other hand, WHNP-A2c was found to be rich in RG-I domains, which contained α-L-1,5/1,3,5-arabinan, AG-II, β-D-1,4-galactan and/or AG-I as side chains. The HG domains of WHNP-A2c was released in the form of un-esterified and partly methyl-esterified and/or acetyl-esterified oligogalacturonides with a 1 to 7 degree of polymerization after endo-polygalacturonase degradation.

Conclusion
Our results reveal the structural characteristics of these polysaccharide fractions, which will contribute to elucidating their structure–activity relationships.

Abstract
Background
The prognosis prediction of locally advanced rectal cancer (LARC) was important to individualized treatment, we aimed to investigate the performance of ultra-high b-value DWI (UHBV-DWI) in progression risk prediction of LARC and compare with routine DWI.

Methods
This retrospective study collected patients with rectal cancer from 2016 to 2019. Routine DWI (b = 0, 1000 s/mm2) and UHBV-DWI (b = 0, 1700 ~ 3500 s/mm2) were processed with mono-exponential model to generate ADC and ADCuh, respectively. The performance of the ADCuh was compared with ADC in 3-year progression free survival (PFS) assessment using time-dependent ROC and Kaplan-Meier curve. Prognosis model was constructed with ADCuh, ADC and clinicopathologic factors using multivariate COX proportional hazard regression analysis. The prognosis model was assessed with time-dependent ROC, decision curve analysis (DCA) and calibration curve.

Results
A total of 112 patients with LARC (TNM-stage II-III) were evaluated. ADCuh performed better than ADC for 3-year PFS assessment (AUC = 0.754 and 0.586, respectively). Multivariate COX analysis showed that ADCuh and ADC were independent factors for 3-year PFS (P < 0.05). Prognostic model 3 (TNM-stage + extramural venous invasion (EMVI) + ADCuh) was superior than model 2 (TNM-stage + EMVI + ADC) and model 1 (TNM-stage + EMVI) for 3-year PFS prediction (AUC = 0.805, 0.719 and 0.688, respectively). DCA showed that model 3 had higher net benefit than model 2 and model 1. Calibration curve demonstrated better agreement of model 1 than model 2 and model 1.

Conclusions
ADCuh from UHBV-DWI performed better than ADC from routine DWI in predicting prognosis of LARC. The model based on combination of ADCuh, TNM-stage and EMVI could help to indicate progression risk before treatment.
