On Commutative Continuation of Partial Endomorphisms of Groups
No full textGiven a homomorphic mapping θ of a subgroup A of a group G onto another subgroup B of G, necessary and sufficient conditions for the existence of a supergroup G* of G and an endomorphism θ* of G* such that θ* coincides with θ on A were derived by B. H. Neumann and Hanna Neumann (3). The homomorphism θ is called a partial endomorphism of G and θ* is said to continue, or extend, θ. Necessary and sufficient conditions for the simultaneous continuation of two partial endomorphisms of a group G to total endomorphisms of one supergroup G* ⊇ G were derived by the author (2).</jats:p
Anaphylaxis as a Manifestation of Systemic Mastocytosis: A Case Report and Review of Literature
No full textExtended spectrum beta lactamase producing Escherichia coli tricuspid valve endocarditis
No full textEscherichia coli is a rare cause of endocarditis. This article reports an 82-year-old male with a mechanical aortic valve replacement who was admitted for fever and fatigue. He was diagnosed with a tricuspid valve endocarditis caused by an extended spectrum beta lactamase producing Escherichia coli following positive blood cultures and echocardiography. He received six weeks of imipenem / cilastatin and subsequently improved and was discharged with ambulatory follow ups with his infectious disease specialist.

Clostridioides difficile infections: Epidemiology, correlations and treatment in a Lebanese cohort with use of ATLAS scoring
No full textIntroduction: The objectives of the present study were to investigate epidemiology, correlations, severity, and therapeutic response of Clostridioides difficile infections in a Lebanese tertiary care hospital.
Methodology: In this retrospective cohort study, patients having at least one positive Clostridioides difficile test (antigen glutamate dehydrogenase/GDH with toxins, or PCR) were studied.
Results: Among 58 patients, 20 (34.5%) and 53 (91.4%) had positive antigen GDH and toxins, respectively. PCR was performed in 25 (43.1%) patients without any positive ribotype 027. Fifteen (25.9%) patients were immunocompromised, 35 (60.3%) patients received antibiotics prior to the infection and 34 (58.6%) on proton pump inhibitors. Fifty-four (93%) patients had a resolution of their symptoms after a mean period of 4.2 days of treatment. Twenty-two (38%) participants were treated with oral vancomycin, 11 (19%) with intravenous metronidazole and 23 (39.6%) with both antibiotics. Resolution of symptoms was significantly more rapid with monotherapy (p = 0.007) with no significant difference between vancomycin and metronidazole (p = 0.413). A positive correlation was found between ATLAS score and delay to symptoms resolution (r = 0.553; p < 0.001; N = 54), as well as between ATLAS score and prevalence of complications (p = 0.003).
Conclusions: History of treatment with antibiotics, proton pump inhibitors, and hospital admission during the previous year were prevalent among our patient cohort. Rates of symptomatic resolution were similar with monotherapy and dual therapy
Companinon Dataset for PASTIS : VHR satellite images (SPOT 6-7)
No full text<p>To enhance the spatial resolution and utility of <a href="https://github.com/VSainteuf/pastis-benchmark">PASTIS-R dataset</a>, we introduce PASTIS-HD, which integrates contemporaneous VHR satellite images (SPOT 6-7), resampled to a 1m resolution and converted to 8 bits. This enhancement significantly improves the dataset's spatial content, providing more granular information for agricultural parcel segmentation.</p>
<p>This folder can be added to the PASTIS-R dataset to get the PASTIS-HD version.<br><br>The SPOT images are opendata thanks to the Dataterra Dinamis initiative in the case of the <a href="https://dinamis.data-terra.org/opendata/">"Couverture France DINAMIS" program</a>.<br><br></p>

CMV reactivation in COVID-19 patients: pouring fuel on the fire
No full textSevere SARS-CoV-2 infection could promote CMV reactivation, that further worsens disease prognosis.
This study included admitted patients with recent COVID-19 for one year period in a tertiary hospital, having clinical criteria of CMV reactivation and positive CMV DNAemia.
Fifteen of 559 COVID-19 patients were diagnosed with CMV reactivation (2.7%). 86.6% were male, with a mean age of 63.6 years. Immunodepression was significantly higher in the CMV positive group (p=0.008). Lymphopenia was significantly more important in patients who reactivated CMV (p=<0.001), whereas ferritin level (p=0.019) and IL-6 level (p=0.035) on admission appeared to be significantly lower in this group. There was no significant difference for COVID-19 treatments. ICU admission (p<0 .001) and bacterial infections (p<0.001) appeared to be significant for CMV reactivation. Also, the mortality was significantly higher in the CMV positive group (p=0.042).
This study raises the possible incrimination of lymphopenia, immunosuppression, critical illness, and bacterial infections in CMV reactivation
