Summary: Background: Laboratory experiments are crucial in understanding efficacy of disinfectant products, but without compliance and appropriate application, the effectiveness of products is compromised. This study aims to understand current perceptions and knowledge of healthcare professionals (HCPs) to common cleaning and disinfection routines and microbial contamination, including biofilms, in healthcare environments. Methods: An online survey, including open and closed questions, was developed. Non-probability convenience and purposive sampling were used: those currently or previously in a healthcare profession were eligible. Survey responses were taken over 24 months, including the COVID-19 pandemic. Discussion: 137 participants completed the survey; over 50% were nurses. Surface cleaning frequency increased post COVID-19 from ‘twice a day’ to ‘three/more times a day’. Disinfection frequency reduced from ‘between every patient’ before COVID-19 to ‘twice a day’ afterwards. A multimethod approach to cleaning and disinfection (70.8%) was predominant when considering the best method to deliver infection control. Most areas of clinical settings were identified as high risk (13/19). Most (87.6%) participants had heard the term ‘biofilm’, mainly at conference/study days (60%). 39.1% said they were aware of dry surface biofilms (DSB) in the healthcare environment. Conclusions: There remain mixed views on surface cleaning and disinfection within healthcare. Education is important for understanding microbial contamination and tackling problems. More people than expected had heard the term DSB. Infection control practices seemed consistent across responses, however whether this is reality is unknown. This study provides an initial insight into current opinions/knowledge of HCPs and can form basis for further in-depth investigation.

Mathematics - Number Theory ,Mathematics - Algebraic Geometry ,11G10, 14K10 - Abstract
The category of abelian varieties over $\mathbb{F}_q$ is shown to be anti-equivalent to a category of $\mathbb{Z}$-lattices that are modules for a non-commutative pro-ring of endomorphisms of a suitably chosen direct system of abelian varieties over $\mathbb{F}_q$. On full subcategories cut out by a finite set $w$ of conjugacy classes of Weil $q$-numbers, the anti-equivalence is represented by what we call $w$-locally projective abelian varieties., Comment: 41 pages, revised version following advice by the referee

Abstract Biofilms are ubiquitous in healthcare settings. By nature, biofilms are less susceptible to antimicrobials and are associated with healthcare-associated infections (HAI). Resistance of biofilm to antimicrobials is multifactorial with the presence of a matrix composed of extracellular polymeric substances and eDNA, being a major contributing factor. The usual multispecies composition of environmental biofilms can also impact on antimicrobial efficacy. In healthcare settings, two main types of biofilms are present: hydrated biofilms, for example, in drains and parts of some medical devices and equipment, and environmental dry biofilms (DSB) on surfaces and possibly in medical devices. Biofilms act as a reservoir for pathogens including multi-drug resistant organisms and their elimination requires different approaches. The control of hydrated (drain) biofilms should be informed by a reduction or elimination of microbial bioburden together with measuring biofilm regrowth time. The control of DSB should be measured by a combination of a reduction or elimination in microbial bioburden on surfaces together with a decrease in bacterial transfer post-intervention. Failure to control biofilms increases the risk for HAI, but biofilms are not solely responsible for disinfection failure or shortcoming. The limited number of standardised biofilm efficacy tests is a hindrance for end users and manufacturers, whilst in Europe there are no approved standard protocols. Education of stakeholders about biofilms and ad hoc efficacy tests, often academic in nature, is thus paramount, to achieve a better control of biofilms in healthcare settings.

Mathematics - Number Theory - Abstract
In this paper we introduce the concept of $\mathit{integral}$ $\mathit{Frobenius}$ to formulate an integral analogue of the classical compatibility condition linking the collection of rational Tate modules $V_\lambda(A)$ arising from abelian varieties over number fields with real multiplication. Our main result gives a recipe for constructing an integral Frobenius when the real multiplication field has class number one. By exploiting algorithms already existing in the literature, we investigate this construction for three modular abelian surfaces over $\mathbf{Q}$., Comment: 27 pages, 3 tables.

We assign functorially a $\mathbb{Z}$-lattice with semisimple Frobenius action to each abelian variety over $\mathbb{F}_p$. This establishes an equivalence of categories that describes abelian varieties over $\mathbb{F}_p$ avoiding $\sqrt{p}$ as an eigenvalue of Frobenius in terms of simple commutative algebra. The result extends the isomorphism classification of Waterhouse and Deligne's equivalence for ordinary abelian varieties., Comment: Accepted for publication in Algebra & Number Theory

Mathematics - Number Theory - Abstract
Let $E$ be an elliptic curve over a finite field $k$, and $\ell$ a prime number different from the characteristic of $k$. In this paper we consider the problem of finding the structure of the Tate module $T_\ell(E)$ as an integral Galois representations of $k$. We indicate an explicit procedure to solve this problem starting from the characteristic polynomial $f_E(x)$ and the $j$-invariant $j_E$ of $E$. Hilbert Class Polynomials of imaginary quadratic orders play here an important role. We give a global application to the study of prime-splitting in torsion fields of elliptic curves over number fields., Comment: Accepted for publication by International Journal of Number Theory, 12 pages

If $D$ is the definite quaternion algebra over $\qu$ of discriminant $p$, we compute, for any prime $p>3$, the number of infinite dimensional cusp forms on $D^*$ which are trivial at infinity, tamely ramified at $p$, and have given conductor $N$ away from $p$. We include a detail explanation of a Deuring--type correspondence between supersingular elliptic curves in characteristic $p$ and a certain double coset arising from the adelic points of $D^*$., Comment: 32 pages

Moist/hydrated biofilms have been well-studied in the medical area, and their association with infections is widely recognized. In contrast, dry-surface biofilms (DSBs) on environmental surfaces in healthcare settings have received less attention. DSBs have been shown to be widespread on commonly used items in hospitals and to harbor bacterial pathogens that are known to cause healthcare-acquired infections (HAI). DSBs cannot be detected by routine surface swabbing or contact plates, and studies have shown DSBs to be less susceptible to cleaning/disinfection products. As DSBs are increasingly reported in the medical field, and there is a likelihood they also occur in food production and manufacturing areas, there is a growing demand for the rapid in situ detection of DSBs and the identification of pathogens within DSBs. Raman microspectroscopy allows users to obtain spatially resolved information about the chemical composition of biofilms, and to identify microbial species. In this study, we investigated Staphylococcus aureus mono-species DSB on polyvinylchloride blanks and stainless steel coupons, and dual-species (S. aureus/Bacillus licheniformis) DSB on steel coupons. We demonstrated that Raman microspectroscopy is not only suitable for identifying specific species, but it also enables the differentiation of vegetative cells from their sporulated form. Our findings provide the first step towards the rapid identification and characterization of the distribution and composition of DSBs on different surface areas.

Patients with severe aortic stenosis are increasingly treated with transcatheter aortic valve implantation (TAVI) as a safer option to surgical aortic valve replacement (sAVR). Similar to many other heart diseases, after the specific therapeutic intervention patients are eligible for cardiac rehabilitation (CR) for the purpose of functional recovery. Thus far, CR after both sAVR and TAVI has been used to a limited extent, as shown by the availability of only two meta-analyses including 5 studies and 6 studies, respectively. Recent observational studies reported a significant improvement in functional indexes such as the Barthel scale and the 6-minute walk test (6MWT). We evaluated the outcome of CR in patients after TAVI treatment by measuring changes in the commonly used Barthel scale and 6MWT and adding the short physical performance battery (SPPB) scale as an index to assess lower extremity function. All indexes demonstrated a significant improvement, namely p

- Abstract
• Klebsiella pneumoniae is able to remain on surfaces as a dry surface biofilm. • After 4 weeks, culturability of K pneumoniae from DSB is low but viability remains high. • Transfer of bacteria from the DSB is reduced over prolonged periods of time. • The survival of K pneumoniae raises questions as to its persistence in the healthcare environment. Dry surface biofilms (DSB) are widespread in healthcare settings presenting a challenge to cleaning and disinfection. Klebsiella pneumoniae has been a focus of attention due to antibiotic resistance and the emergence of hypervirulent strains. Few studies have demonstrated K pneumoniae survival on surfaces following desiccation. DSB were formed over 12 days. Bacterial culturability and transfer were investigated following DSB incubation up to 4 weeks. Bacterial viability in DSB was investigated with live/dead staining using flow cytometry. K pneumoniae formed mature DSB. After 2 and 4 weeks of incubation, transfer from DSB was low (<55%) and reduced further (<21%) following wiping. Culturability at 2 and 4 weeks varied although viability remained high indicating viable but non culturable state (VBNC). K pneumoniae was removed from surfaces by mechanical wiping as shown with DSB of other species. Although culturability was reduced over time, bacteria remained viable up to 4 weeks incubation, proving the need for robust cleaning regimens. This is the first study confirming K pneumoniae survival on dry surfaces as a DSB. The presence of VBNC bacteria indicated that K pneumoniae can for extended periods, raising questions about its persistence on surfaces. [ABSTRACT FROM AUTHOR]

El presente artículo se propone analizar la modalidad que adopta la evaluación de la escritura en dos operativos que indagan los aprendizajes realizados por los estudiantes a la finalización de la escolaridad primaria, que corresponde al sexto año. Nos referimos al Tercer Estudio Regional Comparativo (UNESCO, 2015), organizado por el Laboratorio Latinoamericano de Evaluación de la Calidad de la Educación (LLECE-UNESCO) y el Operativo Nacional de Evaluación (ONE) llevado a cabo en 2013 por la Dirección Nacional de Información y Evaluación de la Calidad Educativa (DiNIECE, 2014) en Argentina. Asimismo, retoma aportes teóricos significativos en la investigación acerca de los procesos implicados en la escritura, presenta los principales resultados obtenidos por los sujetos examinados en los dos estudios mencionados, considerando algunos aspectos centrales de los diseños curriculares del nivel, en el país de referencia. Esto resulta relevante en tanto que el TERCE parte del análisis curricular de los países participantes. Cabe señalar que la indagación de la escritura se ha ido incorporando tardíamente a los programas de evaluación de la calidad educativa, principalmente por la dificultad que conlleva el análisis de las producciones textuales en abordajes a gran escala. Sin embargo, constituye una habilidad central dentro del marco conceptual de “habilidades para la vida” (Atorresi, 2005).

Background Secondary prevention is not adequately implemented after myocardial infarction (MI). We assessed the effect on quality of care and prognosis of a long-term, relatively intensive rehabilitation strategy after MI. Methods We conducted a multicenter, randomized controlled trial in patients following standard post-MI cardiac rehabilitation, comparing a long-term, reinforced, multifactorial educational and behavioral intervention with usual care. A total of 3241 patients with recent MI were randomized to a 3-year multifactorial continued educational and behavioral program (intervention group; n = 1620) or usual care (control group; n = 1621). The combination of cardiovascular (CV) mortality, nonfatal MI, nonfatal stroke, and hospitalization for angina pectoris, heart failure, or urgent revascularization procedure was the primary end point. Other end points were major CV events, major cardiac and cerebrovascular events, lifestyle habits, and drug prescriptions. Results End point events occurred in 556 patients (17.2%). Compared with usual care, the intensive intervention did not decrease the primary end point significantly (16.1% vs 18.2%; hazard ratio [HR], 0.88; 95% confidence interval [CI], 0.74-1.04). However, the intensive intervention decreased several secondary end points: CV mortality plus nonfatal MI and stroke (3.2% vs 4.8%; HR, 0.67; 95% CI, 0.47-0.95), cardiac death plus nonfatal myocardial infarction (2.5% vs 4.0%; HR, 0.64; 95% CI, 0.43-0.94), and nonfatal MI (1.4% vs 2.7%; HR, 0.52; 95% CI, 0.31-0.86). A marked improvement in lifestyle habits (ie, exercise, diet, psychosocial stress, less deterioration of body weight control) and in prescription of drugs for secondary prevention was seen in the intervention group. Conclusion The GOSPEL Study is the first trial to our knowledge to demonstrate that a multifactorial, continued reinforced intervention up to 3 years after rehabilitation following MI is effective in decreasing the risk of several important CV outcomes, particularly nonfatal MI, although the overall effect is small.

- Abstract
Background: For exercise prescription, rating of perceived exertion is the subjective tool most frequently used in addition to methods based on percentage of peak exercise variables. The aim of this study was the validation of a subjective method widely called the Talk Test (TT) for optimization of training intensity in patients with recent myocardial revascularization.Design and methods: Fifty patients with recent myocardial revascularization (17 by coronary artery bypass grafting and 33 by percutaneous coronary intervention) were enrolled in a cardiac rehabilitation programme. Each patient underwent three repetitions of the TT during three different exercise sessions to evaluate the within-patient and between-operators reliability in assessing the workload (WL) at TT thresholds. These parameters were then compared with the data of a final cardiopulmonary exercise testing, and the WL range between the individual aerobic threshold (AeT) and anaerobic threshold (AnT) was considered as the optimal training zone.Results: The within-patient and between-operators reliability in assessing TT thresholds were satisfactory. No significant differences were found between patients’ and physiotherapists’ evaluations of WL at different TT thresholds. WL at Last TT+ was between AeT and AnT in 88% of patients and slightly

- Abstract
Background: Exercise prescription based on percentage of peak exercise variables has many limitations in patients taking beta-blockers. The aim of this study was to evaluate efficacy and safety of a training protocol based on the rating of perceived exercise (RPE) in patients taking beta-blockers after cardiac surgical revascularization.Design and methods: 71 patients treated with beta-blockers after recent coronary artery bypass grafting were randomly allocated to two different programmes with training intensity adjusted to keep heart rate close to first ventilatory threshold (36 subjects, AeT group) or RPE between grades 4 and 5 of 10-point category-ratio BORG scale (35 subjects, RPE group).Results: In the RPE group, mean training workloads and heart rate values were significantly higher than in the AeT group; during the last week of the programme, six RPE patients were training very close to anaerobic threshold. Aerobic peak capacity increased similarly in the two groups. Considering the potential effects on training intensity of prescriptions based on percentages of peak exercise variables, we found that only percentage heart rate reserve and peak workload methods were reliable in defining a safe upper limit of training intensity, with values of 50% and 65% respectively.Conclusions: Self-regulation of exercise training intensity between grades 4 and 5 of the 10-point category-ratio BORG scale is effective but may promote overtraining in some patients without significant functional advantages. For these reasons, RPE method should be integrated with objective indices based on percentage of heart rate reserve or of peak workload.

- Abstract
Patients with severe aortic stenosis are increasingly treated with transcatheter aortic valve implantation (TAVI) as a safer option to surgical aortic valve replacement (sAVR). Similar to many other heart diseases, after the specific therapeutic intervention patients are eligible for cardiac rehabilitation (CR) for the purpose of functional recovery. Thus far, CR after both sAVR and TAVI has been used to a limited extent, as shown by the availability of only two meta-analyses including 5 studies and 6 studies, respectively. Recent observational studies reported a significant improvement in functional indexes such as the Barthel scale and the 6-minute walk test (6MWT). We evaluated the outcome of CR in patients after TAVI treatment by measuring changes in the commonly used Barthel scale and 6MWT and adding the short physical performance battery (SPPB) scale as an index to assess lower extremity function. All indexes demonstrated a significant improvement, namely p<0.001 with the Barthel scale, p=0.043 for the 6MWT, and p=0.002 for SPPB. These results confirm the significant improvement of the Barthel scale and 6MWT reported in the previous meta-analysis and suggest the utility of SPPB as a further index of efficacy of CR in patients with severe aortic stenosis treated with TAVI.

- Abstract
Spontaneous rectus sheath hematoma (RSH) is an uncommon and often clinically misdiagnosed cause of abdominal pain, characterized by a presence of blood within rectus muscle sheath, with palpable mass. Hemorrhage may originate from the epigastric artery and branches or directly from rectus sheath rupture. The most frequent cause of hematoma is anticoagulant therapy. Diagnosis is based on ultrasonography and computed tomography. Conservative treatment and, in case of active bleeding, intravascular embolization is the treatment of choice, while surgery is indicated in case of failure of endovascular procedure or in patients with intra-abdominal rupture causing hemodynamic instability and abdominal compartment syndrome. Here we present a case of RSH that developed after hip replacement surgery in a patient on anticoagulant therapy and dual antiplatelet therapy.

- Abstract
Objective: To estimate the relationship between structural changes in the heart and in the carotid arteries in hypertensives and to analyze the correlations between these structural changes and cardiovascular risk factors., Methods: We studied 76 subjects (39 men and 27 women, mean age 45+/-7 years) with mild-to-moderate untreated and uncomplicated hypertension. All of the subjects underwent ambulatory blood pressure monitoring, M-mode echocardiography for evaluation of their left ventricular mass and B-mode high-resolution ultrasonography to determine their carotid arterial wall thickness., Results: The mean intimal plus medial thickness of the common carotid artery was found to be related significantly and independently to the left ventricular mass indexed by the body surface area. In multivariate analysis, age and the high-density lipoprotein cholesterol level were related strongly to the intimal plus medial thickness, whereas the clinic systolic blood pressure, average night-time systolic blood pressure and glycemia were the most important determinants of the left ventricular mass index. Logistic regression analysis suggested that the thickness of the posterior left ventricular wall was a stronger predictor of the carotid intima-medial thickness than were age and the high-density lipoprotein cholesterol level., Conclusion: The carotid wall thickness and left ventricular mass of hypertensives are related independently; nevertheless the main determinants of structural cardiac and vascular changes are probably different.
