Coronaviridae constantly infect human and animals causing respiratory, gastroenteric or systemic diseases. Over time, these viruses have shown a marked ability to mutate, jumping over the human-animal barrier, thus becoming from enzootic to zoonotic. In the last years, numerous therapeutic protocols have been developed, mainly for severe acute respiratory syndromes in humans. The aim of this review is to summarize drugs or other approaches used in coronavirus infections focusing on different roles of these molecules or bacterial products on viral adhesion and replication or in modulating the host's immune system. Within the "One Health" concept, the study of viral pathogenic role and possible therapeutic approaches in both humans and animals is essential to protect public health.Interleukins (IL)-17, IL-22, and IL-31 play roles in human atopic dermatitis (AD), but scant information is available on canine AD. Histopathological assessment for interleukin expression is a challenge due to a lack of canine specific antibodies. To evaluate the mRNA and protein expression of IL-17 and IL-22, and mRNA expression of IL-31 and their receptors in the skin of healthy and atopic dogs, seventeen atopic (10 with and 7 without an active infection) and 13 healthy privately owned dogs were sampled. RNAscope® In situ hybridization (ISH) for IL-17, IL-22, IL-31, and their receptors was performed on archived canine skin samples. Simultaneously, indirect immunofluorescence (IIF) was performed for IL-17 and IL-22. RNAscope® ISH probes were validated by RT-PCR and RNAscope® ISH on cytospin preparations of peripheral blood mononuclear cells from atopic dogs. IL-17, IL-22, IL-31, and their receptors were successfully detected by RNAscope® ISH and by IIF (IL-17 and IL-22) in both atopic and healthy canine skin. There was no significant difference in the expression of interleukins and their receptors between healthy and atopic skin with or without active infection. Data from both methodologies were similar. The role and the relationship among those proteins in atopic skin is unclear from this study results. Data from IIF and ISH were overlapping and support each other. Fresh skin samples taken at different times during the development of atopic dermatitis might better assess the role that interleukins and their receptors play in AD.The intestinal tract is a target for the deoxynivalenol (DON), which has adverse effects in animals and humans' health by affecting intestinal functions. Phenethyl isothiocyanate (PEITC) is an important degradation product of glucosinolates (GSLs), belonging to an anti-nutritional factor that affects the digestion and absorption of nutrients in the animals' intestinal. However, little attention has been paid to the interaction and its mechanism between DON and PEITC. Therefore, the purpose of this study was to assess the effects of PEITC on DON-induced cytotoxicity and inflammation, and explore the potential mechanisms in IPEC-J2 cells. Our results showed that DON exposure could decrease the cell viability and pro-inflammatory cytokine expression in IPEC-J2 cells in a dose-dependent manner. PEITC treatment at the concentrations of 1.25-5 μM had no significant effect on IPEC-J2 cells viability, but above 10 μM of PEITC treatment significantly reduced the cell viability. Interestingly, 1.25-5 μM of PEITC treatment could suppress 4 μM of DON-induced decrease in cell viability and increase in pro-inflammatory cytokine expression. Meanwhile, the protein ratios of p-p65/p-65 and p-IκBα/IκBα were markedly decreased in the groups treated with 1.25-5 μM PEITC compared to DON exposure alone. However, the protective effects of PEITC treatment were significantly blocked after pre-treatment with LPS, NF-κB activator, in IPEC-J2 cells. In conclusion, these findings indicated that the nontoxic dose of PEITC could alleviate DON-induced cytotoxicity and inflammation responses via suppressing the NF-κB signaling pathway in IPEC-J2 cells. Our results provide a new theoretical basis for the rational addition of rapeseed meal in animal feedstuff.Sow health is related to farm productivity and sustainability, but the increased resistance of bacteria to antibiotics in the pig industry has led to a decline in resistance to disease and environmental pollution. 5-Aminolevulinic acid (5-ALA) is considered a feed additive to replace antibiotics, but the effect of 5-ALA on gut microbiota has not been studied. In this study, we fed 12 healthy Landrace × Large White two-line hybrid sows with different concentrations of 5-ALA; blood and fecal samples were obtained after 110 days of pregnancy, and 16S rRNA amplicon sequencing was performed. The alpha diversity of the gut microbiota in sows was not significant among the sows fed different concentrations of 5-ALA. PCoA revealed a significant (P less then 0.05) difference in the gut microbiota composition with different 5-ALA groups. LEfSe revealed that 5-ALA increased relative abundance of Streptococcus, while Myroides was enriched in CK group. Functional prediction of Tax4Fun showed that different concentrations of 5-ALA significantly (P less then 0.05) increased the mean relative abundance of KEGG pathways involved in core microbiota cellular processes, environmental information processing, and genetic information processing. In summary, 5-ALA changed bacterial community composition of gut microbiota, reduced colonization of some pathogenes and increased the relative abundance of some probiotics. These results provide a theoretical basis for the healthy breeding of pigs.The promise of using induced pluripotent stem cells (iPSCs) for cellular therapies has been hampered by the lack of easily isolatable and well characterized source cells whose genomes have undergone minimal changes during their processing. click here Blood-derived late-outgrowth endothelial progenitor cells (EPCs) are used for disease modeling and have potential therapeutic uses including cell transplantation and the translation of induced pluripotent stem cell (iPSC) derivatives. However, the current isolation of EPCs has been inconsistent and requires at least 40-80 mL of blood, limiting their wider use. In addition, previous EPC reprogramming methods precluded the translation of EPC-derived iPSCs to the clinic. Here a series of clinically-compatible advances in the isolation and reprogramming of EPCs is presented, including a reduction of blood sampling volumes to 10 mL and use of highly efficient RNA-based reprogramming methods together with autologous human serum, resulting in clinically relevant iPSCs carrying minimal copy number variations (CNVs) compared to their parent line.
There are a number of factors that influence blood loss during and after primary total knee arthroplasty (TKA) and revision TKA (rTKA). The purpose of this study was to provide a factorial assessment that would aid surgeons in managing expected blood loss in rTKA, when compared to TKA. The first question asked was the blood loss and transfusions between TKA and rTKA and the second question was risk factors for blood loss after rTKA.

Blood loss in any rTKA is higher than in TKA by a factor of 2.

A retrospective single-centre consecutive series of rTKA between 2006 and 2018 was performed. Based on the rTKA types identified in joint registries, 4 rTKA cohorts were created aseptic minor rTKA, aseptic major rTKA, 1st stage, and 2nd stage septic rTKA. A consecutive TKA cohort from the same study period was used to create a propensity score matched cohort with the aseptic major rTKA cohort.

A total of 622 rTKA were identified. Aseptic major rTKA had double the median blood loss than TKA. The lowest blood loss was observed in the TKA group followed by aseptic minor rTKA, and the highest in 2nd stage septic rTKA. The median total blood loss was higher in all rTKA by a factor ranging between 1.38 and 2.17. Higher age, female gender, lower preoperative hemoglobin, chronic heart disease and history of myocardial infarction were risk factors for increased blood loss. The type of rTKA performed was not predictive of blood loss in the linear regression analysis.

Blood loss after rTKA is 1.38 to 2.17-fold higher than after TKA. The blood loss observed in 2nd stage septic rTKA and aseptic major rTKA was the highest. Older female patients, with a low preoperative hemoglobin, were identified to be at the highest risk of blood loss after rTKA. Strategies for further blood loss reductions need to be utilised to the fullest extent for these procedures.

Computer-assisted navigation in total knee arthroplasty (TKA) has existed for more than 20 years, although its use has been marginal. Its benefits are still largely debated, especially its efficacy for achieving the desired postoperative alignment.

A neutral hip-knee-ankle (HKA) angle (180°±3°) will be achieved in at least 85% of cases and there will be no difference between the different types of navigation systems used.

In this retrospective, single-center, single-surgeon study, all the TKAs completed between September 2003 and December 2017 were included, giving a total of 753 navigated TKAs Navitrack group 196 Natural Knee II implants (Zimmer) with the Navitrack-OS Knee system (Zimmer CAS); Brainlab group 557 implants (196 Profix, Smith & Nephew and 361 LCS, DePuy) with the Brainlab Vector Vision system. The aim of navigation was independent of the preoperative alignment and was always to achieve a neutral HKA mechanical axis (180°±3°). The primary endpoint was the postoperative HKA angle. This ients with a high BMI were more likely to be outliers (p=0.015).

To evaluate the effectiveness of new treatments, whether conservative or surgical, a self-administered questionnaire for hip pain targeted at physically active patients 18 to 60 years of age, named the international Hip Outcome Tool-33 (iHOT-33), was developed and validated in 2012. Since there is no French version available and we are acutely aware of transcultural variations, we conducted a prospective study to 1) translate, and then 2) validate this questionnaire into international French.

The iHOT-33-Fr questionnaire is a valid and reliable tool for evaluating hip pain in a young, francophone population.

Translation of the questionnaire was done according to the standardized method described by Beaton and the final version of the iHOT-33-Fr was validated using the COSMIN methodology. The data were collected prospectively at multiple sites. The reliability of the iHOT-33-Fr questionnaire was evaluated using the intraclass correlation coefficient (ICC) and its internal consistency using Cronbach's alpha. The standard error of measurement and minimum detectable change were calculated. The construct validity was evaluated using Pearson's correlation coefficient by comparing the iHOT-33-Fr with the Hip disability and Osteoarthritis Outcome Score (HOOS-Fr) and Nonarthritic Hip Score (NAHS-Fr).

In all, 101 patients filled out the questionnaires. The ICC was 0.87. The Cronbach alpha was 0.95. The standard error of measurement was 6.4 and the minimum detectable change was 1.8. The correlation between the iHOT-33-Fr and the HOOS-Fr was 0.86, while the correlation between the iHOT-33-Fr and the NAHS-Fr was 0.75.

Our results show that the metrological qualities of the iHOT-33-Fr are comparable to those of the original version and the versions translated into other languages. This study demonstrates that the iHOT-33-Fr is valid, reproducible and comparable to the original iHOT-33. It can be used by francophone surgeons treating symptomatic hip disease in young, active patients.
