Review
BACKGROUND
The sarcoid is the most common equine cutaneous neoplasm. Evidence-based treatment of this condition is often lacking, and selection of treatment modality based on clinical experience or anecdotal evidence.
OBJECTIVES
To assess the quality of the currently available best evidence regarding the treatment of the equine sarcoid.
STUDY DESIGN
Systematic review.
METHODS
In compliance with PRISMA guidelines, literature searches were performed in PUBMED, Web of Science, CAB Abstracts, EMBASE (Ovid) and Scopus in April 2021. Included papers were required to describe an interventional study examining sarcoid treatment strategy, of level 4 evidence or greater. The case definition required confirmation of at least some included lesions on histopathology, and a minimum of 6 months of follow-up was required on treated cases. Studies were assessed by two independent reviewers (KO, CD). Data extraction was performed manually, followed by risk of bias assessment. Methodological quality was assessed using the GRADE system.
RESULTS
In total, 10 studies were included in the review. Case definition was confirmed via histopathology in all included lesions in 60% of papers. Time to follow-up was variably reported. Overall risk of bias ranged from 'some concerns' to 'critical'. Reported sarcoid regression rate ranged from 28% to 100% on an individual sarcoid level, and 9%-100% on a whole horse level. Transient local inflammation was reported following most treatment strategies, with further adverse events reported infrequently.
MAIN LIMITATIONS
Review methodology excluded a large proportion of available literature regarding the equine sarcoid. Significant heterogeneity between included studies prevented quantitative synthesis and most included papers were at significant risk of bias, indirectness, and imprecision.
CONCLUSIONS
There is insufficient evidence currently available to recommend one sarcoid treatment over another. There is an urgent need for sufficiently powered, randomised, placebo-controlled trials in order to allow more definitive comparison of the efficacy of different treatment strategies.

Review
Mastitis is a common condition in rabbit (Oryctolagus cuniculus) does, especially in rabbitries where mammae inflammations are the leading pathological expression of Staphylococcus aureus infections in reproductive females. It affects both the litter and the lactating female, including subsequent lactations. Non-septic (i.e. galactostasis and cystic mastitis) and septic (i.e. Mastitis acuta; including Mastitis gangrenosa; and Mastitis chronica) mammary inflammations are acknowledged; however, the literature is scarce regarding non-septic inflammations or subclinical mastitis. Thus, the present systematic review highlights and summarizes the existing data concerning mastitis in rabbit does, including diagnosis and treatment plans.

Review
Platynosomum sp. is a parasite that infects the liver and biliary tract of domestic and wild cats, causing platynosomiasis. A systematic review with meta-analysis was performed to determine the global prevalence and distribution of Platynosomum sp. based on epidemiological studies and case reports. A total of 73 articles met the inclusion criteria, including 46 studies of an epidemiological nature and 27 case report articles, comprising 35 affected animals. Meta-analysis of epidemiological studies revealed an overall prevalence of 17.8%, with high heterogeneity. Central America had the highest prevalence at 64.1%, followed by South America at 15.1%. Necropsy was the primary diagnostic method, followed by morphological detection of eggs in faeces at 29.3% and 12.5%, respectively. The analysis of case reports highlighted a greater number in South America and confirmed the presence of the parasite in countries where no epidemiological studies were obtained. The most infected animals were those that met the criteria of being mixed-breed, over 4 years old, and having unrestricted outdoor access, but no gender predilection was observed. General comorbidities were the most observed, followed by icterus. In addition, pathological changes were observed in the necropsied animals of the case reports, and the presence of thickening of the ducts and gallbladder was mainly identified, followed by fibrosis and hyperplasia, linked to the presence of an adult parasite. In conclusion, this systematic review with meta-analysis revealed a significant prevalence of Platynosomum sp. at a global level, mainly in the Americas, and that comprehensive studies are necessary for a more reliable prevalence, considering that this is a parasite of great importance for feline medicine.

Review
Multiple sclerosis (MS) is a chronic inflammatory, autoimmune, and neurodegenerative disease of the central nervous system (CNS), characterized by demyelination and axonal loss. It is induced by attack of autoreactive lymphocytes on the myelin sheath and endogenous remyelination failure, eventually leading to accumulation of neurological disability. Disease-modifying agents can successfully address inflammatory relapses, but have low efficacy in progressive forms of MS, and cannot stop the progressive neurodegenerative process. Thus, the stem cell replacement therapy approach, which aims to overcome CNS cell loss and remyelination failure, is considered a promising alternative treatment. Although the mechanisms behind the beneficial effects of stem cell transplantation are not yet fully understood, neurotrophic support, immunomodulation, and cell replacement appear to play an important role, leading to a multifaceted fight against the pathology of the disease. The present systematic review is focusing on the efficacy of stem cells to migrate at the lesion sites of the CNS and develop functional oligodendrocytes remyelinating axons. While most studies confirm the improvement of neurological deficits after the administration of different stem cell types, many critical issues need to be clarified before they can be efficiently introduced into clinical practice.

Review
OBJECTIVES
To systematically assess the magnitude of suicidal behavior among PsA patients and identify associated risk factors. Also identify common genes or coinherited single nucleotide polymorphisms (SNPs) implicated in suicidal behavior and PsA.
METHODS
Based on the PRISMA guidelines, we conducted a systematic literature review of the online databases PubMed/Medline, Web of Science, and EMBASE from inception to May 2022. Full-text original articles that describe suicidal behavior in PsA patients were eligible. All registered genome-wide association study (GWAS) data in the GWAS catalog database for PsA and psychiatric traits, such as suicidal behavior, and depression, were downloaded for further analysis.
RESULTS
A total of 48 articles were identified, and 6 were relevant to the study question .Among the 122,160 PsA patients, 700 had suicidal behavior (0,57%). The range of age in one study was between 30 and 49 years, and 64% of PsA patients with suicidal behavior were female. Among 13,899 PsA patients 74 had suicidal ideation (0.53%) and 125 suicide attempts occurred (0.9%). In two studies, among 17,383 patients, 13 complete suicides occurred (0.07%). A genetic haplotype on chromosomal region 6p21.1, spanning from 29,597,596 to 32,251,264 Mb, contains predisposing SNPs for PsA and depression. 6p21.1-6p21.3 is the chromosomal region containing the HLA genes of classes I, II and III.
CONCLUSION
Suicide behavior in PsA patients was associated with depression and other psychiatric comorbidities. Further evidence supports a genetic origin, at least partly. Awareness of these findings can help clinicians to recognize suicide behavior and prevent suicide attempts.

Review
Arboviruses represent a real public health problem globally and in the Central African subregion in particular, which represents a high-risk zone for the emergence and re-emergence of arbovirus outbreaks. Furthermore, an updated review on the current arbovirus burden and associated mosquito vectors is lacking for this region. To contribute to filling this knowledge gap, the current study was designed with the following objectives: (i) to systematically review data on the occurrence and distribution of arboviruses and mosquito fauna; and (ii) to identify potential spillover mosquito species in the Central African region in the last 30 years. A web search enabled the documentation of 2454 articles from different online databases. The preferred reporting items for systematic reviews and meta-analyses (PRISMA) and the quality of reporting of meta-analyses (QUORUM) steps for a systematic review enabled the selection of 164 articles that fulfilled our selection criteria. Of the six arboviruses (dengue virus (DENV), chikungunya virus (CHIKV), yellow fever virus (YFV), Zika virus (ZIKV), Rift Valley fever virus (RVFV), and West Nile virus (WNV)) of public health concern studied, the most frequently reported were chikungunya and dengue. The entomological records showed >248 species of mosquitoes regrouped under 15 genera, with ( = 100 species), ( = 56 species), and ( = 52 species) having high species diversity. Three genera were rarely represented, with only one species included, namely, , , and , but individuals of the genera and were not identified at the species level. We found that two species ( and ) colonised the same microhabitat and were involved in major epidemics of the six medically important arboviruses, and other less-frequently identified mosquito genera consisted of competent species and were associated with outbreaks of medical and zoonotic arboviruses. The present study reveals a high species richness of competent mosquito vectors that could lead to the spillover of medically important arboviruses in the region. Although epidemiological studies were found, they were not regularly documented, and this also applies to vector competence and transmission studies. Future studies will consider unpublished information in dissertations and technical reports from different countries to allow their information to be more consistent. A regional project, entitled "Ecology of Arboviruses" (EcoVir), is underway in three countries (Gabon, Benin, and Cote d'Ivoire) to generate a more comprehensive epidemiological and entomological data on this topic.

Review
BACKGROUND
Silver nanoparticles (AgNPs) are widely used in medicine owing to their antiseptic activity and inducing cell death. Despite AgNPs' importance in nano-engineering and medical benefits, animal studies have shown silver toxicity can damage multiple organs such as the lungs, liver, kidneys, intestines, and brain. Several investigations revealed the correlation between Ag administration by different methods with impaired cognitive and behavioral abilities. Therefore, this systematic review aimed to conclude on the existing evidence of impairments in learning and memory that were changed in rodents exposed to AgNPs.
METHODS
Main searches were retrieved in Google Scholar, Scopus, Web of Science, and PubMed databases from 1979 to 2022. Eligibility Criteria were applied to select and extract 15 articles among 892.
RESULTS
Learning and memory abilities of rats and mice in screened studies were evaluated with MWM, NORT, PAL, T-maze, Y-maze, contextual fear conditioning, Radial Arm Maze and Carousel Maze test. Data have shown various sizes from 10 to 100 nm could affect the results of tests among animals exposed to AgNPs compared with control animals. However, in some treatments, results achieved from tests have not demonstrated significant differences between control and treated groups.
CONCLUSION
Studies have revealed that treatment with Ag-NPs of different sizes can impair learning and memory skills in rats and mice.

Review
BACKGROUND
COVID-19 screening is an effective nonpharmaceutical intervention for identifying infected individuals and interrupting viral transmission. However, questions have been raised regarding its effectiveness in controlling the spread of novel variants and its high socioeconomic costs. Therefore, the optimization of COVID-19 screening strategies has attracted great attention.
OBJECTIVE
This review aims to summarize the evidence and provide a reference basis for the optimization of screening strategies for the prevention and control of COVID-19.
METHODS
We applied a methodological framework for scoping reviews and the PRISMA-ScR (Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews) checklist. We conducted a scoping review of the present publications on the optimization of COVID-19 screening strategies. We searched the PubMed, Web of Science, and Elsevier ScienceDirect databases for publications up to December 31, 2022. English publications related to screening and testing strategies for COVID-19 were included. A data-charting form, jointly developed by 2 reviewers, was used for data extraction according to the optimization directions of the screening strategies.
RESULTS
A total of 2770 unique publications were retrieved from the database search, and 95 abstracts were retained for full-text review. There were 62 studies included in the final review. We summarized the results in 4 major aspects: the screening population (people at various risk conditions such as different regions and occupations; 12/62, 19%), the timing of screening (when the target population is tested before travel or during an outbreak; 12/62, 19%), the frequency of screening (appropriate frequencies for outbreak prevention, outbreak response, or community transmission control; 6/62, 10%), and the screening and detection procedure (the choice of individual or pooled detection and optimization of the pooling approach; 35/62, 56%).
CONCLUSIONS
This review reveals gaps in the optimization of COVID-19 screening strategies and suggests that a number of factors such as prevalence, screening accuracy, effective allocation of resources, and feasibility of strategies should be carefully considered in the development of future screening strategies.

BACKGROUND
People with heart failure experience substantial disease burden that includes low exercise tolerance, poor health-related quality of life (HRQoL), increased risk of mortality and hospital admission, and high healthcare costs. The previous 2018 Cochrane review reported that exercise-based cardiac rehabilitation (ExCR) compared to no exercise control shows improvement in HRQoL and hospital admission amongst people with heart failure, as well as possible reduction in mortality over the longer term, and that these reductions appear to be consistent across patient and programme characteristics. Limitations noted by the authors of this previous Cochrane review include the following: (1) most trials were undertaken in patients with heart failure with reduced (< 45%) ejection fraction (HFrEF), and women, older people, and those with heart failure with preserved (≥ 45%) ejection fraction (HFpEF) were under-represented; and (2) most trials were undertaken in a hospital or centre-based setting.
OBJECTIVES
To assess the effects of ExCR on mortality, hospital admission, and health-related quality of life of adults with heart failure.
SEARCH METHODS
We searched CENTRAL, MEDLINE, Embase, CINAHL, PsycINFO and Web of Science without language restriction on 13 December 2021. We also checked the bibliographies of included studies, identified relevant systematic reviews, and two clinical trials registers.
SELECTION CRITERIA
We included randomised controlled trials (RCTs) that compared ExCR interventions (either exercise only or exercise as part of a comprehensive cardiac rehabilitation) with a follow-up of six months or longer versus a no-exercise control (e.g. usual medical care). The study population comprised adults (≥ 18 years) with heart failure - either HFrEF or HFpEF.
DATA COLLECTION AND ANALYSIS
We used standard Cochrane methods. Our primary outcomes were all-cause mortality, mortality due to heart failure, all-cause hospital admissions, heart failure-related hospital admissions, and HRQoL. Secondary outcomes were costs and cost-effectiveness. We used GRADE to assess the certainty of the evidence.
MAIN RESULTS
We included 60 trials (8728 participants) with a median of six months' follow-up. For this latest update, we identified 16 new trials (2945 new participants), in addition to the previously identified 44 trials (5783 existing participants). Although the existing evidence base predominantly includes patients with HFrEF, with New York Heart Association (NYHA) classes II and III receiving centre-based ExCR programmes, a growing body of trials includes patients with HFpEF with ExCR undertaken in a home-based setting. All included trials employed a usual care comparator with a formal no-exercise intervention as well as a wide range of active comparators, such as education, psychological intervention, or medical management. The overall risk of bias in the included trials was low or unclear, and we mostly downgraded the certainty of evidence of outcomes upon GRADE assessment. There was no evidence of a difference in the short term (up to 12 months' follow-up) in the pooled risk of all-cause mortality when comparing ExCR versus usual care (risk ratio (RR) 0.93, 95% confidence interval (CI) 0.71 to 1.21; absolute effects 5.0% versus 5.8%; 34 trials, 36 comparisons, 3941 participants; low-certainty evidence). Only a few trials reported information on whether participants died due to heart failure. Participation in ExCR versus usual care likely reduced the risk of all-cause hospital admissions (RR 0.69, 95% CI 0.56 to 0.86; absolute effects 15.9% versus 23.8%; 23 trials, 24 comparisons, 2283 participants; moderate-certainty evidence) and heart failure-related hospital admissions (RR 0.82, 95% CI 0.49 to 1.35; absolute effects 5.6% versus 6.4%; 10 trials; 10 comparisons, 911 participants; moderate-certainty evidence) in the short term. Participation in ExCR likely improved short-term HRQoL as measured by the Minnesota Living with Heart Failure (MLWHF) questionnaire (lower scores indicate better HRQoL and a difference of 5 points or more indicates clinical importance; mean difference (MD) -7.39 points, 95% CI -10.30 to -4.77; 21 trials, 22 comparisons, 2699 participants; moderate-certainty evidence). When pooling HRQoL data measured by any questionnaire/scale, we found that ExCR may improve HRQoL in the short term, but the evidence is very uncertain (33 trials, 37 comparisons, 4769 participants; standardised mean difference (SMD) -0.52, 95% CI -0.70 to -0.34; very-low certainty evidence). ExCR effects appeared to be consistent across different models of ExCR delivery: centre- versus home-based, exercise dose, exercise only versus comprehensive programmes, and aerobic training alone versus aerobic plus resistance programmes.
AUTHORS' CONCLUSIONS
This updated Cochrane review provides additional randomised evidence (16 trials) to support the conclusions of the previous 2018 version of the review. Compared to no exercise control, whilst there was no evidence of a difference in all-cause mortality in people with heart failure, ExCR participation likely reduces the risk of all-cause hospital admissions and heart failure-related hospital admissions, and may result in important improvements in HRQoL. Importantly, this updated review provides additional evidence supporting the use of alternative modes of ExCR delivery, including home-based and digitally-supported programmes. Future ExCR trials need to focus on the recruitment of traditionally less represented heart failure patient groups including older patients, women, and those with HFpEF.

Review
Prevention and control of food pathogens are important for public health and O157:H7 infections are known as one of the most important food-borne bacterial diseases transmitted to humans. Vegetables can be a major source of O157:H7 bacteria. Bacteriophages have been considered in recent years as a natural method for controlling pathogens with minimal damage to the quality of vegetables. The performance of these natural antimicrobial agents is affected by various factors including time, temperature, phage and bacterial dose, method of phage application and origin of phages. The aim of the present study was to conduct a systematic review of the works that have examined the effect of different factors to reduce O157:H7 bacteria by its specific phages and model their effect. In our study, 10 articles were chosen after applying the inclusion and exclusion criteria mentioned in the methodology. The multivariate regression results showed that time, temperature, and method of phage application revealed a positive influence on the phage function, and with each unit of increase, the O157:H7 reduction increases by 0.4 %, 3 % and 0.94 % respectively, and 6 % for phage dose, but not statistically significant (P = 0.44). In addition, commercial-type phages were more effective than wild-type phages and this result was statistically significant (Beta = 0.99; P = 0.001). The results of this study indicate that the various factors, such as temperature, time, method of phage application and type of vegetables can play an important role to reduce O157:H7 in vegetables.
