Abstract
The use of veterinary drugs is of similar importance to that of human drugs in addressing health challenges. In this context, pharmaceuticals and their metabolites inevitably enter soil and water in unknown quantities. Therefore, this study collects and analyzes drug data from 2020 for 50 dairy farms located in Germany. The most frequently used substance group is antibiotics (40.13%), followed by antiphlogistics (18.86%), antiparasitics (13.09%), and hormones (9.29%). Treatment frequencies record the number of days per year on which an average animal on a farm was treated with a substance. The calculated values range from 0.94 to 21.69 d/yr and are distributed heterogeneously across farms. In this study, on average, a cow was treated on 6 d in 2020: 2.34 d with antibiotics, 1.07 d with antiphlogistics, 0.76 d with antiparasitics, and 0.41 d with hormones. In addition to individual farm management practices, other factors are related to treatment frequency. Farms with a veterinary care contract used more hormonal substances than farms without a care contract. In addition, higher milk yield coincides with more frequent treatments with antiphlogistic or hormonal substances. Other related factors include grazing, longevity, farm size, and use of a claw bath. Our study represents an important first step in describing the amounts and determinants of veterinary drugs used in livestock farming. Such insights on magnitudes and farm parameters are essential to estimate potential environmental effects and derive strategies to reduce veterinary drug use.

Abstract
Venetoclax + hypomethylating agent (Ven-HMA) is currently the standard frontline therapy for older/unfit patients with newly diagnosed acute myeloid leukemia (ND-AML). Our objective in the current retrospective study of 301 adult patients (median age 73 years; 62% de novo) with ND-AML was to identify molecular predictors of treatment response to Ven-HMA and survival; European LeukemiaNet (ELN) genetic risk assignment was favorable 15%, intermediate 16%, and adverse 69%. Complete remission, with (CR) or without (CRi), count recovery, was documented in 182 (60%) patients. In multivariable analysis, inclusive of mutations only, "favorable" predictors of CR/CRi were NPM1 (86% vs. 56%), IDH2 (80% vs. 58%), and DDX41 (100% vs. 58%) and "unfavorable" TP53 (40% vs. 67%), FLT3-ITD (36% vs. 63%), and RUNX1 (44% vs. 64%) mutations; significance was sustained for each mutation after adjustment for age, karyotype, and therapy-related qualification. CR/CRi rates ranged from 36%, in the presence of unfavorable and absence of favorable mutation, to 91%, in the presence of favorable and absence of unfavorable mutation. At median follow-up of 8.5 months, 174 deaths and 41 allogeneic stem cell transplants (ASCT) were recorded. In multivariable analysis, risk factors for inferior survival included failure to achieve CR/CRi (HR 3.4, 95% CI 2.5-4.8), adverse karyotype (1.6, 1.1-2.6), TP53 mutation (1.6, 1.0-2.4), and absence of IDH2 mutation (2.2, 1.0-4.7); these risk factors were subsequently applied to construct an HR-weighted risk model that performed better than the ELN genetic risk model (AIC 1661 vs. 1750): low (n = 130; median survival 28.9 months), intermediate (n = 105; median 9.6 months), and high (n = 66; median 3.1 months; p < .001); survival in each risk category was significantly upgraded by ASCT. The current study identifies genotype signatures for predicting response and proposes a 3-tiered, CR/CRi-based, and genetics-enhanced survival model for AML patients receiving upfront therapy with Ven-HMA.

Abstract
Introduction Les troubles de la fonction thyroïdienne au cours des viroses sont décrits dans la littérature. Le SARS-Cov2 entraîne des manifestations systémiques notamment une atteinte thyroïdienne. Patients et méthodes C’est une étude monocentrique type cohorte rétrospective incluant les patients hospitalisés pour une pneumopathie Covid-19 (septembre 2020–février 2022) et ayant une perturbation du bilan thyroïdien. Les patients ayant des antécédents de pathologies thyroïdiennes ont été exclus. Les caractéristiques clinico-biologiques ont été relevées. Résultats Durant cette période, 1237 patients ont été hospitalisé pour une pneumopathie Covid-19. Nous avons inclus 256 patients en excluant 33 patients ayant un antécédent de dysthyroïdie. Il s’agissait de 128 (57 %) femmes et 95 (43 %) hommes. L’âge moyen était de 74 ans. Il s’agissait de 191 (85,7 %) cas d’hyperthyroïdie fruste, 24 (10,7 %) cas d’hypothyroïdie fruste et 8 (3,6 %) cas d’hypothyroïdie dont 6 cas de thyroïdite d’Hashimoto avec des anticorps antithyroperoxydases positifs. Il y avait une normalisation du bilan thyroïdien des cas de dysthyroïdie fruste dont le bilan a été contrôlé à distance de l’infection. Conclusion L’infection Covid-19, par le billais du stress hypoxique, la sécrétion de glucocorticoïdes et la libération de cytokines pro inflammatoires, peut perturber la fonction thyroïdienne. L’atteinte semble le plus souvent spontanément réversible dans le cas des dysthyroïdies fruste mais l’attention est toujours requise chez les à haut risque de survenu de fibrillation auriculaire. Ceci augmenterait le risque thromboembolique déjà majoré par la COVID-19. D’authentique cas de thyroïdite auto-immunes ont aussi été découvertes. Ceci confirme la relation déjà soulevé entre SARS-cov2 et auto-immunité.

Abstract
OBJECTIVE This study investigated the effects of administering saline, 100 or 250 μg of gonadotrophin releasing hormone (GnRH) on ovarian response, synchrony of oestrus and ovulation and chronic stress response in Bos indicus cattle. DESIGN Randomised control. METHODS Animals were either left untreated (n = 20) or on day 0 treated with an intravaginal progesterone releasing device and either saline (n = 24), 100 μg (n = 35), or 250 (n = 35) μg of GnRH, intramuscular (IM). Blood was sampled 1.4 h after administration of treatment to monitor concentrations of luteinising hormone (LH) and P4 in serum and again 5 days later. On day 5 intravaginal P4 releasing device were removed, cloprostenol was administered IM and again 8 h later. Oestrus and ovulation were then monitored with ultrasonography for 6.5 days. Hair was clipped on day 55 for analysis of hair cortisol concentrations (HCC). RESULTS No significant differences were found between Saline and GnRH treatments in the odds of inducing a new corpus luteum (CL) and the synchrony of oestrus or ovulation. HCC did not differ significantly between treatments. Mean concentrations of LH in serum on day 0 were less in the Saline compared to 100 and 250 μg GnRH treatments but did not differ between different doses of GnRH. CONCLUSION Mean concentrations of LH and the odds of inducing a new CL were not increased after administering 250 μg compared to 100 μg of GnRH. Animal handling events in the study did not influence HCC. Further research is needed to better optimise responses to GnRH in B. indicus cattle.

Abstract
The equine infectious anaemia virus (EIAV) is one of the most serious equine diseases worldwide. There is scarce information on the epizootiology of equine infectious anaemia (EIA) in Saudi Arabia. Given the importance of the equine industry in Saudi Arabia, this cross- -sectional study aims to provide information about the prevalence of EIAV based on serological surveillance of the equine population in the country. A total of 4728 sera samples were collected (4523 horses and 205 donkeys) between December 2017 and November 2019. All samples were tested using commercially available EIAV ELISA. All tested samples showed negative results for EIAV antibodies with a 95% confidence interval. The results provided evidence that Saudi Arabia's equine populations (horses and donkeys) are currently free of EIAV. The results also suggest the need for continuous monitoring of EIAV and strict regulation when importing horses from other countries.

Abstract
Resource recovery and prevention of environmental pollution are key goals for sustainable development. It is widely reported that agro-industrial activities are responsible for the discharge of billions of liters of wastewater to the environment. Anaerobic digestion of these energy rich agro-industrial wastewaters can simultaneously mitigate environmental pollution and recover embedded energy as methane gas. In this study, an assessment of mono- and co-digestion of cheese whey wastewater (CWW) and poultry slaughterhouse wastewater (PSW) was conducted in 2.25-L lab-scale anaerobic digesters. Treatment combinations evaluated included CWW (R1), PSW (R2), 75:25 CWW:PSW (R3), 25:75 CWW:PSW (R4), and 50:50 CWW:PSW (R5). The digestion efficiencies of the mixed wastewaters were compared to the weighted efficiencies of the corresponding combined mono-digested samples. R4, with a mixture of 25% CWW and 75% PSW, achieved the greatest treatment efficiency. This corresponded with an average biodegradability of 84%, which was greater than for R1 and R2 at 68.5 and 71.9%, respectively. Similarly, R4 produced the highest average cumulative methane value compared to R1 and R2 at 1.22× and 1.39× for similar COD loading, respectively. The modified Gompertz model provided the best fit for the obtained methane production data, with lag time decreasing over progressive treatment cycles. PCoA and heatmap analysis of relative microbial abundances indicated a divergence of microbial communities based on feed type over the treatment cycles. Microbial community analysis showed that genus Petrimonas attained the highest relative abundance (RA) at up to 38.9% in the first two cycles, then subsequently decreased to near 0% for all reactors. Syntrophomonas was highly abundant in PSW reactors, reaching up to 36% RA. Acinetobacter was present mostly in CWW reactors with a RA reaching 56.5%. The methanogenic community was dominated by Methanothrix (84.3–99.9% of archaea). The presence of phosphate and Acinetobacter in CWW feed appeared to reduce the treatment efficiency of associated reactors. Despite Acinetobacter being strictly aerobic, previous and current results indicate its survival under anaerobic conditions, with the storage of phosphate likely playing a key role in its ability to scavenge acetate during the digestion process.

Abstract
New cationic Gemini surfactant (CGS) molecules were synthesized and investigated as anticorrosive materials for carbon steel (CS) in 1 M HCl solution by chemical, electrochemical and theoretical studies such as DFT and MDS approaches. The anticorrosion efficacy increased with the increase in the CGS concentration. It reached 95.66% at 5 × 10−3 M of the CGS molecule using PDP measurements. PDP studies confirm that the CGS molecule acts as a mixed inhibitor. The EIS outcomes were explained by an equivalent circuit in which a constant phase element (CPE) rather than a double-layer capacitance (Cdl) was exploited to donate a more precise fit of the experimental outcomes. The CGS molecule follows the Langmuir isotherm as it is chemically adsorbed onto the surface of CS. To explore the kinetic and adsorption mechanisms, the thermodynamic characteristics of the activation and adsorption processes were assessed under the impact of temperature. Frontier molecular orbitals (FMOs) were achieved by the density functional theory (DFT) method. The study of interatomic interactions at the [CS (Fe(110))]/CGS level was discussed using molecular dynamics (MD) simulation.

Abstract
The anticorrosion efficiency of two polymer compounds, namely polystyrene (PS), polybutylene terephthalate (PBT), against the corrosion of SABIC iron (S-Fe) in 1.0 M HCl solution was investigated. The anticorrosion efficiency was estimated by chemical and electrochemical measurements. The anticorrosion efficiency increased with the increase in the concentration of the polymer compounds and reduction in temperature. All the obtained corrosion data confirmed the anticorrosion strength in the presence of PS and PBT compounds, such as the decreasing values of the corrosion current density, capacity of the double layer, and weight reduction, while the values of the charge-transfer resistance increased. Also, the pitting potential values moved in the noble (+) direction. The anticorrosion efficiency of the PBT compound was higher than that of the PS compound, which was 95.98% at 500 ppm concentration for PBT while for PS it was 93.34% according to polarization measurements. The anticorrosion activity occurred by the adsorption of PS and PBT compounds on the surface of S-Fe according to the Langmuir isotherm. The polarization curves indicated that the PS and PBT compounds were mixed-type inhibitors. Density functional theory (DFT) and Monte Carlo simulation (MC) were performed for the two polymer compounds. The computational quantum functions were found to be in agreement with the experimental results. Top and side views for adsorption of the two dimers over Fe (110) surface.![]()

Abstract
This work focuses on the use of natural parsley oil as a safe, eco-friendly and cost-effective inhibitor for dissolution of X80 carbon steel (X80CS) in 0.5 M H2SO4 solution. Electrochemical and chemical measurements and theoretical studies were utilized to determine the inhibitory vigor of parsley oil. The inhibition efficacy increases with an increase in the parsley oil concentration and a decrease in temperature. It reached 95.68% at 450 ppm of parsley oil. The inhibition process is explained by spontaneous adsorption of the oil on the X80CS. Adsorption is described by the Langmuir isotherm model. The polarization data demonstrate that parsley oil is categorized as a mixed inhibitor with a dominant control of the cathodic reaction. Parsley oil inhibits the pitting corrosion of X80CS in the presence of NaCl solution by moving the pitting potential to a more positive mode indicating protection against pitting attack. The thermodynamic parameters for activation and adsorption were computed and interpreted. The four chemical components in natural parsley oil were examined using density functional theory (DFT). Monte Carlo (MC) simulation was performed to study the adsorption of parsley oil on the X80CS surface. The outcomes confirmed that the Apiole molecule is the most effective in the inhibition process. This work focuses on the use of natural parsley oil as a safe, eco-friendly and cost-effective inhibitor for dissolution of X80 carbon steel (X80CS) in 0.5 M H2SO4 solution.![]()

Abstract
Introduction L’empagliflozine utilisé pour le traitement du diabète de type 2 a démontré son efficacité mais peut être responsable d’effets indésirables comme l’acidocétose diabétique euglycémique (ACDeu). C’est une complication rare favorisée par la déshydratation ou un état anorexigène. Nous rapportons le cas d’ACDeu associé à l’empagliflozine au décours d’une infection Covid 19. Observation Il s’agit d’un homme âgé de 49 ans diabétique sous empagleflozine. Il consulte pour un syndrome grippal, dyspnée et anorexie. À l’examen, il avait une glycémie à 1,68 g/l avec une acétonurie et une glycosurie. Il était polypnéique avec une saturation périphérique en O2 à 95 %. Le reste de l’examen était sans anomalie. À la biologie, il avait une acidose métabolique non compensé avec un trou anionique à 28,55 et une insuffisance rénale aiguë fonctionnelle. Devant la dyspnée le test RT-PCR coronavirus SARS cov2 a été pratiqué et il était positif. Le diagnostic d’ACDeu iatrogène à l’empagleflozine a été retenu et il a été arrêté. Le patient a été mis sous insulinothérapie associée à une hydratation et un apport adapté en glucose avec une bonne évolution clinico-biologique. Conclusion L’infection Covid 19 peut être responsable d’une déshydratation, une anorexie et une perturbation du métabolisme glucidique. Ces facteurs favorisent la survenue de l’ACDeu chez le patient diabétique sous empagliflozine. La glycémie normale ou faiblement élevée n’exclut pas le diagnostic. Cette observation nous rappelle l’intérêt de l’arrêt des antidiabétiques oraux lors d’une infection Covid 19. Le pronostic est bon si la prise en charge est précoce et adaptée.

Abstract
The inhibition potency of expired thiamine or vitamin B1 (VB1) and riboflavin or vitamin B2 (VB2) against SABIC iron corrosion in 0.5 M H2SO4 solutions was investigated using chemical and electrochemical techniques. Theoretical studies such as DFT and MC simulations were performed on both VB1 and VB2 inhibitors to obtain information related to the experimental results. It has been found that the inhibition efficacy assigned from all measurements used increases with increasing concentration of the two expired vitamins and reduces at elevated temperatures. It reached 91.14% and 92.40% at 250 ppm of VB1 and VB2, respectively. The inhibition was explicated by the adsorption of the complex formed between expired vitamins and ferrous ions on the SABIC iron surface. The adsorption was found to obey the Langmuir isotherm model. Galvanostatic polarization demonstrated that the two expired vitamins act as an inhibitor of the mixed type. These expired vitamins have proven effective in inhibiting the pitting corrosion induced by the presence of Cl- ions. The pitting potential is transferred to the positive values showing resistance to pitting damage. The theoretical parameter values are consistent with experimental results.

Abstract
Objective: Impedance based biosensing provides a unique, highly sensitive electrical approach to biomolecule detection, cell growth, and other biological events. To date, an impedance change due to the cell growth has been considered as a solution to detect some changes in a cell’s behavior. The impedance change detection is normally measured via an impedance analyzer which is expensive and also cumbersome. Rapid and definitive diagnosis of viral infections is imperative in patient treatment process. Early detection followed by appropriate lifestyle and treatment may result to a longer, healthier life. Certain patients require continues monitoring that may require regular visits to hospitals which is not practical. Therefore, a continuous home healthcare device is needed to monitor and detect any change in a patient’s health condition. Methods & Results: In this research, a novel sensor and healthcare monitoring system is modeled, simulated, developed, and tested to detect viruses by detecting the change in the impedance due to antibodies and antigens binding. First, COMSOL simulation tool is used to develop a model to prove the concept. The model predicts increasing impedance during functionalization of electrodes with antibodies and after antigen binding steps. Second, to understand how nanoscale electrode size and spacing would affect biosensing assay (antibody-based affinity binding of a protein antigen), a model using COMSOL is developed. Third, Field Programmable Gate Arrays (FPGA) based signal processing system is developed as well to be connected to analog to digital converter (ADC) to acquire the current and voltage readings of the sensors over time. This healthcare monitoring system is used to continuously monitoring a patient’s condition and reports any changes in the impedance readings which represents virus detection or at least change in the cell’s behavior. Conclusions: The proposed sensor model is simulated, tested and verified via COMSOL and the FPGA prototype is tested and it verified the COMSOL model. This work reports that the proposed sensor can be used to detect viruses via detecting a change in the impedance.

Abstract
Abstract
Introduction
Acute kidney injury (AKI) is a significant in-hospital complication in patients undergoing percutaneous coronary interventions (PCI) and has been shown to be associated with poor outcomes. Prior studies have shown an upward trend of AKI post PCI which may be related to a multitude of factors. In this study, we aim to discern whether the recent changes in AKI definition, awareness of risk calculators, and preventive measures have been effective in changing the inclining trend.
Methods
Patients who underwent PCI during hospitalization were identified retrospectively in the Nationwide Readmission Database (NRD) from January 2010 to December 2014. All patients older than 18 years were included in the current study. Patient demographics and comorbidities were identified using appropriate ICD-9 codes. The primary outcome is the temporal trends of AKI following PCI and secondary outcomes are temporal trends in mortality, length of stay and hospitalization cost in patients with AKI. Continuous variables were expressed as means ± standard deviation or median (IQR), and categorical variables were expressed as percentages (%). All statistical tests were two-sided.
Results
Among the 2,712,473 patients who underwent PCI from 2010 to 2014, 162,286 (6%) patients developed AKI post PCI. Mean age was 69.22±12.34 years and 65% of them were males. The percentage of cases with AKI rose almost twofold from 2010 to 2014 (4.8% to 8.1%, p-value <0.005), despite the lack of a significant change in patient's demographics and comorbidities over the years. Among patients with a history of Chronic Kidney Disease (CKD) the incidence of AKI increased from 20.3% to 24.2%, and in patients without CKD history the incidence of AKI almost doubled (2.6% to 5.0%) from 2010 to 2014. There was a slight decrease in in-hospital mortality (9.4% to 8.8%) and median length of stay (7 days to 5 days), and a slight increase in the mean cost of hospitalization ($124,755.1 to $133,902.17) from 2010 to 2014.
AKI Incidence and mortality trend
Conclusion
This large cohort study shows a consistent uptrend of AKI in patients undergoing PCI from 2010 to 2014. Despite this, the mortality and length of stay are decreasing while the cost of hospitalization only slightly increased in patients with AKI. Thus, future drives to implement renal protective measures and advanced studies to identify new preventive therapies are needed to reduce the incidence of AKI post-PCI.

Abstract
Thermoelectric Graphite sheet has been studied numerically due to their ability to convert directly heat to electricity. Electro-thermal heat transfer equations coupling to initial and boundary conditions, are solved using finite difference and finite element schemes. The obtained results of both numerical techniques show good qualitative and quantitative agreements. In addition, the results of our numerical models present good conformity with the experimental result of Luo et al.. The voltage difference, the temperature variation, the Seebeck coefficient, the figure of merit and the maximum efficiency of graphite sheet are determined numerically. The ZT of the graphite sheet is calculated to be 1.27 at a temperature of 850 K for a graphite sheet surface of 0.26×0.25 cm2.

Abstract
BACKGROUND Despite the high prevalence of type 2 diabetes mellitus in Gulf countries, standards of diabetes care at the primary care level have not been widely studied. AIM To compare the results of diabetes clinical indicators from the American Diabetes Association (ADA) 2017 guidelines to the reference benchmarks in the Behavioral Risk Factor Surveillance System. MATERIALS AND METHODS A cross-sectional analysis of electronic medical records in 643 randomly selected adult patients with type 2 diabetes was undertaken. A checklist enabled the collection of sociodemographic, clinical, biochemical, and quality measurement data. Data were analyzed using Stata 9.0. The chi-squared test was used to compare two or more proportions. RESULTS There were 643 patients (male = 60.3%; female = 39.7%), and the majority (71.7%) aged between 40 and 64 years. Common comorbidities were dyslipidemia (72.3%), hypertension (70%), obesity (50.1%), and preobesity (overweight) (37.9%). Over 15% were smokers. The most commonly prescribed diabetes medications were metformin (89.9%), dipeptidyl peptidase-4 inhibitors (61.1%), and sulfonylureas (49.3%). Only 35.5% (p < 0.0001) of patients met the reference glycated hemoglobin (HbA1c) cutoff level of 7.0%. The reference level for blood pressure control was met by 70.2% (p < 0.0001) and for low-density lipoprotein cholesterol, 73.8% (p < 0.0001). Albuminuria was present in 39.2%, and very low vitamin D level (<20 ng/ml) in 39.1%. Most patients had annual foot (89.6%, p < 0.0001) and eye (72.3%, p < 0.0001) examinations. Only 39.9% had referrals for dietary counseling, and there were lower rates of referrals and uptake for pneumococcal, influenza, and hepatitis B vaccines. Most (76.2%) did not have screening for depression. CONCLUSION The majority of the results met the ADA standards, while glycemic control, dietary counseling, and screening for depression were poor in comparison to the standards. Continuing education for clinicians, patient education for self-management, and targeted weight management are recommended.
