In accordance with Article 6 of Regulation (EC) No 396/2005, the applicant Corteva submitted a request to the competent national authority in Finland to modify the existing maximum residue levels (MRLs) for the active substance clopyralid in various commodities. selleck chemicals llc The data submitted in support of the request were found to be sufficient to derive MRL proposals for wheat, oat and for animal commodities. An adequate analytical method for enforcement is available to control the residues of clopyralid in the plant commodities under consideration at the validated limit of quantification (LOQ) of 0.01 mg/kg. The analytical methods for animal commodities are validated at LOQ of 0.01 mg/kg, but demonstration of extraction efficiency is lacking. Based on the risk assessment results, EFSA concluded that the short-term and long-term intake of residues resulting from the use of clopyralid according to the reported agricultural practices is unlikely to present a risk to consumer health provided that risk mitigation measures are in place to avoid clopyralid residues in rotational and/or succeeding crops.The conclusions of the EFSA following the peer review of the initial risk assessments carried out by the competent authorities of the rapporteur Member State, Germany, and co-rapporteur Member State, Denmark, for the pesticide active substance Bacillus amyloliquefaciens strain QST 713, formerly Bacillus subtilis strain QST 713, are reported. The context of the peer review was that required by Commission Implementing Regulation (EU) No 844/2012, as amended by Commission Implementing Regulation (EU) No 2018/1659. The conclusions were reached on the basis of the evaluation of the representative uses of Bacillus amyloliquefaciens strain QST 713 as a fungicide on strawberry (field and greenhouse uses) and grapes (field use). link2 The reliable end points, appropriate for use in regulatory risk assessment, are presented. Missing information identified as being required by the regulatory framework is listed. Concerns are identified.The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as 'High risk plants, plant products and other objects'. This Scientific Opinion covers the plant health risks posed by the following commodities (i) dormant and free of leaves 1-year-old bare rooted plants and (ii) free of leaves 1-year-old liners of Ficus carica imported from Israel, taking into account the available scientific information, including the technical information provided by Israel. The relevance of any pest for this opinion was based on evidence following defined criteria. Four EU quarantine pests, Euwallacea fornicatus, Hypothenemus leprieuri, Scirtothrips dorsalis and Spodoptera frugiperda, and 11 EU non-regulated pests fulfilled all relevant criteria and were selected for further evaluation. For these pests, the risk mitigation measures proposed in the technical dossier from Israel were evaluated separately for bare rooted plants and for liners, taking into account the possible limiting factors. For these pests, an expert judgement was given on the likelihood of pest freedom taking into consideration the risk mitigation measures acting on the pest, including uncertainties associated with the assessment. The estimated degree of pest freedom varied among the pests evaluated. Aonidiella orientalis and Russellaspis pustulans were the most frequently expected pests on the imported bare rooted plants, and Scirtothrips dorsalis on liners. The Expert Knowledge Elicitation indicated, with 95% certainty, that between 9,585 and 10,000 bare rooted plants per 10,000 would be free of Aonidiella orientalis and Russellaspis pustulans and between 9,456 and 10,000 liners per 10,000 would be free of Scirtothrips dorsalis.The histological lesions associated with an infection with the Sars-CoV-2 are mainly observed at the respiratory tract level, but not exclusively. Analyses of these lesions strongly beneficied from autopsic studies allowing us to improve the knowledge of the pathophysiology mechanisms of this emerging infectious disease. link3 Cytological analyses, notably those obtained from broncho-alveolar lavages, poorly contribute to the Covid-19 diagnosis, but can be usefull for eliminate a couple of differential diagnoses. Although non specific, the lesions observed in the pulmonary parenchyma can be directly associated with the presence of the Sars-CoV-2 thanks to ancillary tools allowing its detection. Indeed, the presence of the virus can be detected using immunohistochemistry, in situ hybridization, molecular biology and/or electron microscopy approaches. Several uncertainties still exist concerning the direct role due to the Sars-CoV-2 in the observed lesions which can be due too to a cardiovascular failure and/or to the treatment(s) received in intensive care units. Thus, it is critical to keep going to increase our efforts for the tissue analyses, notably thanks to the autopsies of Covid-19 patients, in order to better understand the consequences of this infectious disease, and, particularly according the epidemiological factors and the different associated morbidities. An increased knowledge will participate to the further therapeutic strategies against the Covid-19. This review adresses the main histological lesions of the lung parenchyma currently described in patients infected by the Sars-CoV-2.
We aimed to prospectively evaluate the prognostic value of seminal anti-sperm antibodies (ASA) screening in couples prepared for intracytoplasmic sperm injection (ICSI).

A prospective comparative study was conducted, including 184 non-azoospermic infertile men scheduled for ICSI. For each patient, detection of ASA in seminal plasma using the ELISA technique was done and its relation to standard semen parameters and ICSI outcomes, including fertilization, embryo development, and pregnancy rates, was analyzed.

Sperm count, motility, and morphology were negatively affected by existence of seminal ASA (
 = 0.012, 0.006, and 0.011, respectively). However, no statistically significant difference was detected between patients with positive and negative seminal ASA regarding the median values of fertilization (56.3%
66.7%,
 = 0.091), percentage of couples with grade A embryo development (91.4%
89.9%,
 = 0.520), and pregnancy rates (31.4%
32.2%,
 = 0.98) after ICSI.

ICSI seems able to overcome the problem of ASA in semen. The routine screening of ASA in men prepared for ICSI has no additional prognostic value and cannot be recommended for the time being, until more specific antigen-concerned testing can be developed.

Endoscopic resection of extensive esophageal neoplastic lesions is associated with a high rate of esophageal stricture. Most studies have focused on the risk factors for post-endoscopic esophageal stricture, but data on the therapeutic management of these strictures are scarce. Our aim is to describe the management of esophageal strictures following endoscopic resection for early esophageal neoplasia.

We included all patients with an endoscopic resection for early esophageal neoplasia followed by endoscopic dilatation at a tertiary referral center. We recorded the demographic, endoscopic, and histological characteristics, and the outcomes of the treatment of the strictures.

Between January 2010 and December 2019, we performed 166 endoscopic mucosal resections and 261 endoscopic submucosal dissections for early esophageal neoplasia, and 34 (8.0%) patients developed an esophageal stricture requiring endoscopic treatment. The indication for endoscopic resection was Barrett's neoplasia in 15/34 (44.1%) caseysphagia. Circumferential endoscopic esophageal resections should be considered when indicated.The emergence of COVID-19 as a global pandemic has led to a rapid focus on understanding its pathobiology. The constellation of clinical, histological and laboratory findings seen in these patients is similar to other forms of viral pneumonia, but somewhat distinctive aspects exist which may raise the index of suspicion for this disease. The pathological findings are not limited to the respiratory system; cardiovascular, gastrointestinal and renal abnormalities have also been described. Establishing a link between the clinical features and macroscopic and microscopic findings is not only important for the practicing autopsy pathologist, but also for understanding of the disease as a whole. Furthermore, context-sensitive interpretation of diagnostic tests is essential. This article aims to review understanding of clinicopathological correlation in COVID-19, as well as clarifying the role of current diagnostic techniques.The COVID-19 pandemic has reminded pathologists of our significant roles in the management and understanding of rapidly spreading and dangerous pathogens, from identifying the agent to characterizing the clinical pathology to managing the dead. Cellular pathology - through autopsy - has depicted the main features viral pneumonitis, acute lung injury, organising pneumonia, secondary bacterial pneumonia, thrombophilia and infarction, and systemic inflammatory response syndrome with multi-organ failure. These are similar to another viral pandemic of the 20th century, H1N1 influenza; but contrast with the second major more complicated pandemic, that of HIV/AIDS. The outcomes of these infections are compared, along with seasonal influenza and SARS-1-CoV disease. Work to be done on COVID-19 includes characterisation of the emerging 'long COVID' syndrome, and monitoring the complications of therapies and vaccination programs.Whilst much literature has been published since the start of the COVID-19 pandemic, there remains limited knowledge of the autopsy findings following death from SARS-CoV-2 infection. The practicalities of triaging and examining bodies with suspected COVID-19 are complex and the need for full post-mortem must be balanced with the potential risks to mortuary staff. This brief case report describes the features of a COVID-19 autopsy performed at the start of the first phase of the pandemic and highlights some important learning points for trainees engaged in autopsy practice.
Thrombocytopenia was intuitively considered to be associated with higher risk of bleeding and multiple comorbidities after percutaneous coronary intervention (PCI). However, controversial results exist, and the real-world clinical impact of thrombocytopenia in patients undergoing PCI is largely unknown. The aim of this study was to evaluate the influence of baseline thrombocytopenia on the prognosis of patients undergoing PCI.

Using the West China Hospital Inpatient Sample database, patients who underwent PCI were identified from August 2012 to January 2019. Baseline thrombocytopenia was defined as a preprocedural platelet count of 100 × 10
/L or less obtained from a routine blood sample taken within 48 hours before coronary PCI. The clinical effect of the advanced thrombocytopenia group (≤85 × 10
/L), according to the median value of platelet count in the thrombocytopenia cohort, was further assessed. The primary outcome was a composite of in-hospital death, bleeding events, and post-PCI transfusion.

Of 9531 patients enrolled in our study, 936 had baseline thrombocytopenia and 8595 patients did not have.
