Abstract
Background: Apart from the huge worldwide economic losses often occasioned by bovine coronavirus (BCoV) to the livestock industry particularly cattle, continuous surveillance of the virus in cattle and small ruminants is essential in monitoring variations in the virus that could enhance host switching. In this study, we collected rectal swabs from a total of 1,498 cattle, sheep and goats. BCoV detection was based on reverse transcriptase polymerase chain reaction. Sanger sequencing of the partial RNA-dependent RNA polymerase (RdRp) region for postive samples were done and nucleotide sequences were compared with homologous sequences from the GenBank.Results: The study reports a BCoV prevalence of 0.3% consisting of 4 positive cases; 3 goats and 1 cattle. Less than 10% of all the animals sampled showed clinical signs such as diarrhea and respiratory distress except for high temperature which occurred in > 1000 of the animals. However, none of the 4 BCoV positive animals manifested any clinical signs of the infection at the time of sample collection. Bayesian majority-rule cladogram comparing partial and full length BCoV RNA-dependent RNA polymerase (RdRp) genes obtained in the study to data from the GenBank revealed that the sequences obtained from this study formed one large monophyletic group with those from different species and countries. The goat sequences were similar to each other and clustered within the same clade. No major variations were thus observed with our isolates and those from elsewhere.Conclusion: Given that Ghana predominantly practice the extensive and semi-intensive systems of animal rearing, our study highlights the potential for spillover of BCoV to small ruminants in settings with mixed husbandry and limited separation between species.

Abstract
In this work, 3D C f /SiBCN composites were fabricated by polymer infiltration and pyrolysis (PIP) with poly(methylvinyl)borosilazane as SiBCN precursor. The 3D microstructure evolution process of the composites was investigated by an advanced x-ray computed tomography (XCT). The effect of dicumyl peroxide (DCP) initiator addition on the crosslinking process, microstructure evolution and mechanical properties of the composites were uncovered. With the addition of DCP initiator, the liquid precursor can cross-link to solid-state at 120 °C. Moreover, DCP addition decreases the release of small molecule gas during pyrolysis, leading to an improved ceramic yield 4.67 times higher than that without DCP addition. After 7 PIP cycles, density and open porosity of the final Cf/SiBCN composite with DCP addition are 1.73 g·cm -3 and ~10%, respectively, which are 143.0% higher and 30.3% lower compared with the composites without DCP addition. As a result, the flexural strength and elastic modulus of Cf/SiBCN composites with DCP addition (371 MPa and 31 GPa) are 1.74 and 1.60 times higher than that without DCP addition (213 MPa and 19.4 GPa).

Abstract
Background : Infantile-onset inflammatory bowel disease (IO-IBD) patients with interleukin-10/interleukin-10 receptor (IL-10/IL-10R) mutations suffer from more severe and intractable disease. We aimed to investigate the clinical phenotypes and genotypic characteristics of IO-IBD patients with IL-10RA gene mutations. Methods : Data on 22 patients with IO-IBD with IL-10RA gene mutations were retrospectively analyzed, and high-throughput sequencing was used to identify the IL-10RA gene mutations. Results : In 22 patients with IO-IBD with IL-10RA mutations, c.C301T (p.R101W) (86.4%, 19/22) and c.G537A (p.T179T) (36.4%, 8/22) were the most common ones, and one novel mutation was identified (c.635G>C (p.R212P)). Patients had extremely early onset of symptoms, with 81.8% (18/22) having disease onset within 1 month after birth, and median onset time was 8.5 (interquartile range: 3.0–24.0) days. In addition, 77.3% (17/22) of patients had recurrent perianal lesions. Oral ulcers and skin rashes were common extra-intestinal manifestations, accounting for 72.7% (16/22) and 63.6% (14/22), respectively. In this study, three patients underwent enterostomy and one experienced intestinal perforation repair. Thalidomide was used in five patients in this study: one achieved clinical remission, three were clinical improvement and one still had disease activity. Two patients underwent umbilical cord blood transplantation (UCBT) and remained stable. Follow-up showed that the mortality rate was as high as 45% (9/20). Conclusions : In 22 IO-IBD patients with IL-10RA mutations, the most common mutations were c.C301T (p.R101W) and c.G537A (p.T179T). Patient characteristics included extremely early onset of symptoms and extra-intestinal manifestations such as recurrent perianal lesions, oral ulcers, and skin rashes, which were common. UCBT and thalidomide might be effective treatments, although the mortality rate was high in this study.

Abstract

Background: As a response to the COVID-19 pandemic outbreak, strict national policies regarding public behavior were implemented in countries throughout the world, including Europe, America and Australia. Social distancing became the main policy for public behavior, in effect imposing radical changes in people’s everyday life. Thus, mental health may be affected at the general population level and not only among those who have been infected by the disease or have witnessed family members or close ones fall ill. Methods: A cross-sectional online survey was conducted in Norway, UK, USA and Australia during April/May 2020. Participants (n = 3810) were recruited via social media postings by the researchers and the involved universities. Differences between those with and without infection in the family were investigated with chi-square tests and independent t-tests. Multiple regression analyses were used to assess associations between sociodemographic variables and psychological outcomes (worry, loneliness and mental health) in both groups. Results: Compared to their counterparts, participants with infection in the family reported higher levels of worries about themselves (p < 0.05) and their family members (p < 0.001), and had poorer mental health (p < 0.05). However, the effect sizes related to the differences were small. The largest effect (d = 0.24) concerned worries about their immediate family. Poorer psychological outcomes were observed in those who were younger, female, unemployed, living alone and had lower levels of edcuation, yet with small effect sizes. Conclusions: In view of the small differences between those with and without infection, we generally conclude that the mental health effects of the COVID-19 situation are not limited to those who have been infected or have had infection within the family, but extend to the general population.

Abstract
Background Previous studies have indicated that medial meniscal subluxation (MMS) is associated with special types of medial meniscus tears (MMT) and chondral lesions. However, most of these studies lacked arthroscopic findings and did not adjust for possible confounders. The purpose of this study was to explore factors associated with MMS in patients with MMT using multivariate logistic regression analysis. Methods A retrospective analysis of 115 patients who underwent arthroscopic surgery for MMT was conducted. The medial meniscal extrusion (MME) distance was measured on a single mid-coronal magnetic resonance (MR) image, and the MMS group included patients with MME distance ≥3 mm (55 patients with 55 knees). Other patients were included as the control group (60 patients with 60 knees). Demographic and clinical data were collected as variates. A multivariate logistic regression analysis was performed to identify factors associated with MMS. Results In a univariate analysis, the Outerbridge classification (P=0.002) and the type of MMT (P<0.001) were significantly different between the MMS group and the control group. According to unadjusted and age- and body mass index (BMI)-adjusted multivariate logistic regression analysis, the type of MMT was an independent factor associated with MMS. Compared with horizontal tears, radial tears, posterior medial meniscus root tears (PMMRT) and complex tears had approximately 6-fold (adjusted OR 6.468, 95% CI 1.509–27.718, P=0.012), 10-fold (adjusted OR 10.324, 95% CI 1.719–61.989, P=0.011) and 4-fold (adjusted OR 4.458, 95% CI 1.602–12.408, P=0.004) higher associations with MMS, respectively. Conclusion The type of MMT was an independent factor associated with MMS in knees with MMT. Radial tears, PMMRT and complex tears were more likely than horizontal tears to result in MMS. The results suggest that MMT combined with MMS should be noted when managing MMT, especially radial tears, PMMRT and complex tears. Moreover, the results indicate that we must not only preserve the meniscus as much as possible but also restore its position to as close to normal as possible.
"Aneurysmal Bone Cyst of the Pelvis: A Systematic Literature Review"
Authors: Saeed Ayesha , Rometsch Elke , Hurtado-Chong Anahí 
Published: August 2020

Abstract
Background:Aneurysmal bone cysts (ABC) are rare benign, vascular, osteolytic bone lesions. Pelvic ABCs account for 8 -12% of these tumors and no clear guidelines for their treatment are available. To our knowledge, this is the first systematic literature review regarding pelvic ABCs. Our primary objective was to identify treatment modalities and to assess the bone healing, measured as the degree of radiological ossification. Secondary objectives were to describe demographics, tumor characteristics, clinical and functional outcomes and recurrence.Methods: Searches were conducted in PubMed, Cochrane Library, and Web of Science. Based on the scarcity of reports, inclusion criteria were kept broad and comprised primary or recurrent pelvic ABCs, with a minimum follow up of one year and available information on radiological ossification. Data was extracted on the individual patient-level and grouped according to treatment modality. Results:Forty-nine studies reporting on 194 patients were included. The level of evidence was low (29 case reports and 20 retrospective case series) and the reporting of outcomes inconsistent. Patients had a median age of 15 years and 52% were male. Five major treatment groups were identified and divided into 11 subgroups. The largest subgroup was curettage (23%) followed by selective arterial embolization (20%). Most ABCs were located in the ilium. Variations in mean tumor size (4.5-22.2cm) and degree of ossification (60-100%) depended on the treatment modality. Overall, in 77% cases the cyst ossified completely. Recurrence was reported in 22 patients (11%) and 2 patients (1%) died during the course of the treatment.Conclusion:Despite the low quality of reporting, this systematic review provides the first comprehensive overview of pelvic ABC treatment modalities and their radiological and clinical outcomes. Neoadjuvant sclero-embolic treatments appear to be used most in recent years, but further comparative studies and better quality of reporting are needed to determine their effectiveness. Quality of reporting should be improved by following reporting guidelines.Level of Evidence: IV

Authors: ghafouri raziyeh , Yaghmaei Minoo , Khodadadi Sepideh 
Published: August 2020

Abstract
Background: Patient safety is the most important clinical priority, especially in high-risk groups such as infants. Neonatal safety after a C-section is more challenging because despite all efforts and guidelines, patient safety is still a major challenge in the operating room. This meta-synthesis study aimed to investigate the factors affecting neonatal safety during a C-section and to provide improved strategies. Methods: This systematic review was carried out through meta-synthesis. A total of 112 articles were found and finally, 37 articles were selected for research after review. The articles were first reviewed by title and abstract and those which met the inclusion criteria were entered into the study. The inclusion criteria were papers in English and Persian, relevance to neonatal safety and being published before 2019. Exclusion criteria were papers that were not relevant to safety or neonate. In the next step, the quality of the articles was reviewed simultaneously by two separate researchers using the Strengthening the Reporting of Observational studies in Epidemiology" STROBE" and consolidated standards of reporting trials "CONSORT" Review Guidelines. Data were analyzed using content analysis. Results: The most important risk factors of neonatal safety during a C-section included anemia due to early cord clamping, jaundice due to delayed cord clamping, nosocomial infection, hypothermia and hyperthermia, inappropriate positioning of the infant, fall, medication error, operative damage and error in registering infants identity. Conclusion: For improvement of neonatal safety during C-section, it is important to consider teamwork, team and interdisciplinary continuous training through simulation, accurate identification of mothers and accurate registration of mothers and infants' identity on the identification band, accurate medication and right dosage, safely carrying and sleeping, observing infection control tips, maintaining operating room temperature and humidity, cord clamping after 30 seconds before birth and 2 minutes after birth.

Published: August 2020

Abstract
Background

SARS-Cov-2 infects not only adults, but also children, including pediatric surgery patients with acute abdomen. Here, we report a pediatric surgery case with incarcerated inguinal hernia and suspected COVID-19.
Case presentation:

A 11-month-old male was brought to our emergency department with the main complaint of recurrent yellowish-green vomiting that was experienced from one day before admission. High fever and shortness of breath were also reported. This patient was also suffering from moderate dehydration. Neither history of contact with a confirmed case of COVID-19 nor traveling from any local transmission area were found. However, a SARS-CoV-2 rapid antibody test revealed a positive result. A lump in the left scrotum that persisted during admission was found. Fluid resuscitation and nasogastric tube placement for decompression was performed. Manual reduction was attempted but failed to reduce the lump. Accordingly, we decided to perform an emergency high ligation using tertiary protection regulations, i.e., full personal protective equipment (PPE) for COVID-19. Intraoperatively, we found a small intestine loop trapped in the scrotum and stuck in the inguinal canal. Postoperatively, the baby was continued to be managed as a patient with COVID-19 while waiting for the real-time reverse transcription polymerase chain reaction (RT-PCR) results.
Conclusions

During the COVID-19 pandemic, surgeons should always be aware of the possibility of cross-transmission from the patient, since children are also susceptible to SARS-CoV-2 infection. When and wherever possible, surgeons should perform the procedure in the quickest and most effective manner to shorten exposure time with patient and anesthetic aerosols as well as using appropriate PPE.

Abstract
Background: the establishment of filiation by the current ABO, HLA, MNS, Kells and serum tests, pose a real reliability problem. It is then necessary to combine these methods with or to use high-performance methods such as microsatellite genetic analysis or short tandem repeats. This study aimed to compare the short tandem repeat technique with ABO/Rhesus system in combination with electrophoresis of hemoglobin. Methods: Fourteen (14) contested paternity trios were investigated. Blood samples were collected to determine blood groups using the Beth-Vincent method and the type of hemoglobin by electrophoresis. Blood spots on FTA paper were used for the analysis of 16 STR loci (D8S1179, D21S11, D7S820, CSF1PO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, vWA, TPOX, D18S51, D5S818, FGA, Amel) by capillary electrophoresis on the ABI 31310 Genetic Analyzer. The generated sequences were analyzed with GeneMapper® software version 3.2.1. The data were analyzed to determine the paternity index and the probability of paternity. Results: Of the fourteen (14) trios studied, ten (10) cases were probable inclusion, three (03) cases were exclusion and one (01) case was an undetermined paternity outcome with the ABO-Rhesus/ electrophoresis of hemoglobin system. While the analysis of genetic polymorphisms in DNA gave five (05) inclusions versus nine (09) exclusions of paternity. Of the 10 probable inclusion cases given by the ABO-Rhesus/Electrophoresis of hemoglobin system, only 05 cases (50%) were confirmed for inclusion by Short tandem repeat analysis. Conclusion: The analysis of short tandem repeat with sixteen genetic markers is more reliable in determining paternity than ABO-Rhesus/hemoglobin electrophoresis techniques.

Published: August 2020

Abstract
Background: It is controversial about the sex differences in the association of chronic kidney diseases (CKD) and cardiovascular disease (CVD) risk. Thus, we examined CVD risk makers of CKD and non-CKD men and women in China, especially some “non-traditional” ones.Methods: This cross-sectional study used 7999 participants from the China Health and Nutrition Survey in 2009. This study examined the “traditional” risk factors and of CVD, such as lipoprotein cholesterol (LDL-C), total cholesterol (TC) and non-high density lipoprotein cholesterol(non-HDL-C).Also, the “non-traditional” risk factors of CVD were calculated, such as lipoprotein (a)(Lp(a)), white blood cell (WBC) count, visceral adiposity index (VAI) and lipid accumulation product (LAP).Results: Compared with men with CKD, higher levels of TC and LDL-C were observed in women with CKD. Furthermore, compared with men with CKD, the relative difference of WBC count was greater between women with CKD and their non-CKD ones. Meanwhile, the level of LAP and VAI of women with CKD were higher than men with CKD, which indicate the visceral obese. We also observed that the sex by CKD status interactions were statistically significant for TC, LDL-C, non-HDL-C, LAP, VAI and Lp(a) (all p <0.05). After adjusted the covariates, the sex differences effect on CVD risk factors among CKD patients couldn’t be eliminated as well. Conclusions: In CKD situation, women had greater lipid profiles and put on more visceral adiposity than men, which may indicate a higher CVD risk of women with CKD.
Exercise-therapy and education for individuals one year after anterior cruciate ligament reconstruction: a pilot randomised controlled trial

Published: August 2020

Abstract
Background: Guided rehabilitation beyond 6-months is rare following anterior cruciate ligament reconstruction (ACLR), despite high prevalence of unacceptable symptoms and quality of life (QoL). We aimed to: i) determine the feasibility of a randomised controlled trial (RCT) evaluating the effectiveness of a physiotherapist-guided lower-limb focussed exercise-therapy intervention for individuals 1-year post-ACLR with persistent symptoms, and ii) estimate the effects of this intervention compared to a trunk-focussed intervention on knee-related QoL.Design: Participant- and assessor-blinded, pilot feasibility RCT.Methods: Participant eligibility criteria: i) 12–15 months post-ACLR; ii) < 87.5/100 on the Knee injury and Osteoarthritis Outcome Score (KOOS) QoL subscale; and one of: a) one-leg rise test < 22 repetitions; b) single-hop < 90% limb symmetry; or c) Anterior Knee Pain Scale < 87/100. Participants were randomised (2:1 ratio) to lower-limb focussed exercise-therapy and individualised education, or trunk-focussed exercise-therapy and standardised education. Both interventions involved eight face-to-face physiotherapy sessions over 16-weeks, to guide allocated exercise-therapy programs. Feasibility was assessed by: i) recruitment (participants/month), ii) retention (< 20% drop-out), iii) physiotherapy attendance, and iv) unsupervised exercise-therapy program adherence (> 80% of 3 sessions/week). Knee-related QoL was evaluated using the KOOS-QoL subscale and ACL-QoL questionnaire, with between-group differences compared to published minimally important difference (MID) scores (KOOS-QoL = 10 points; ACL-QoL = 12 points).Results: 27 participants (3 participants/month; 48% men, 34 ± 12 years) were randomised. Two did not commence treatment, and two were lost to follow-up (16% drop-out). Physiotherapy attendance was > 80% for both groups but reported adherence to the unsupervised program was low (< 55% of prescribed exercises). KOOS-QoL improvement (mean ± SD) in the lower-limb focussed (23 ± 15) and trunk-focussed (16 ± 12) groups resulted in a between-group difference (mean, 95%CI) lower than the MID (7.1, -12.3 to 26.4). ACL-QoL improvement in the lower-limb focussed (20 ± 17) and trunk-focussed (22 ± 13) groups resulted in a between-group difference lower than the MID (-2.5, -18.2 to 13.2).Conclusions: A larger-scale RCT evaluating the effectiveness of a physiotherapist-guided lower-limb focussed program for individuals 1-year after ACLR with persistent symptoms is feasible. This intervention is associated with large within-group knee-related QoL improvements, but may not be superior to a trunk-focussed intervention.Trial Registration: Prospectively registered (ACTRN12616000564459).
