Survey of drug use and its association with herd-level and farm-level characteristics on German dairy farms. J Dairy Sci 2024; 107:2954-2967. [PMID: 38101741 DOI: 10.3168/jds.2023-23945] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/10/2023] [Accepted: 11/13/2023] [Indexed: 12/17/2023]
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.

Do risk adjustment calculations used by governmental agencies adequately assess risk for infection after colon surgery? Am J Infect Control 2024; 52:463-467. [PMID: 37898319 PMCID: PMC11018117 DOI: 10.1016/j.ajic.2023.10.009] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2023] [Revised: 10/18/2023] [Accepted: 10/21/2023] [Indexed: 10/30/2023]
Abstract
BACKGROUND Surgical site infections (SSIs) following colon surgery are associated with clinical and financial consequences. The Centers for Medicare and Medicaid Services (CMS) and the New York State Department of Health (NYSDOH) use risk adjustment variables to determine quality measure scores. METHODS Among patients in a large public system, surgical risk variables were compared between patients with and without SSIs. Propensity score matching, using CMS and NYSDOH risk variables, created control groups. Receiver Operating Characteristics (ROC) curves were created using current and augmented risk adjustment variables. RESULTS When matched using CMS risk variables, more patients with SSIs had contaminated/dirty wounds, longer duration of surgery, and emergency surgery. The addition of these variables significantly improved the CMS ROC curve. When matching NYSDOH variables, more SSI patients were male, had contaminated/dirty wounds, and tended to be younger. The addition of these variables to the current NYSDOH adjustment criteria did not significantly improve the ROC curve. DISCUSSION The CMS adjustment criteria for colon SSIs do not adequately account for complicated surgeries. The inclusion of additional variables significantly improved the performance of CMS risk adjustment. CONCLUSIONS Until more robust risk adjustment criteria are developed, the reporting of SSIs following colon surgery as a quality measure should be suspended.

Abstract
OBJECTIVES To examine differences in risk factors and outcomes of patients undergoing colon surgery in level 1 trauma centers versus other hospitals and to investigate the potential financial impact of these reportable infections. DESIGN Retrospective cohort study between 2015 and 2022. SETTING Large public healthcare system in New York City. PARTICIPANTS All patients undergoing colon surgery; comparisons were made between (1) all patients undergoing colon surgery at the level 1 trauma centers versus patients at the other hospitals and (2) the nontrauma and trauma patients at the level 1 trauma centers versus the nontrauma patients at other hospitals. RESULTS Of 5,217 colon surgeries reported, 3,531 were at level 1 trauma centers and 1686 at other hospitals. Patients at level 1 trauma centers had significantly increased American Society of Anesthesiology (ASA) scores, durations of surgery, rates of delayed wound closure, and rates of class 4 wounds, resulting in higher SIRs (1.1 ± 0.15 vs 0.75 ± 0.18; P = .0007) compared to the other hospitals. Compared to the nontrauma patients at the other hospitals, both the nontrauma and trauma patients at the level 1 trauma centers had higher ASA scores, rates of delayed wound closure, and of class 4 wounds. The SIRs of the nontrauma patients (1.16 ± 1.29; P = .008) and trauma patients (1.26 ± 2.69; P = .066) at the level 1 trauma center were higher than the SIRs of nontrauma patients in the other hospitals (0.65 ± 1.18). CONCLUSIONS Patients undergoing colon surgery at level 1 trauma centers had increased complexity of surgery compared to the patients in other hospitals. Until there is appropriate adjustment for these risk factors, the use of infections following colon surgery as a reportable quality measure should be re-evaluated.

Abstract
Background: Deep incisional and organ/space surgical site infections (SSIs) after colorectal surgery are associated with adverse outcomes. Multiple antibiotic regimens are recommended for peri-operative prophylaxis, with no particular regimen preferred over another. We compared the prophylaxis regimens used in patients with and without SSIs, and the impact of regimens on the flora involved in SSIs. Patients and Methods: Information was extracted from the National Healthcare Safety Network databank of patients undergoing colorectal surgery from 2015 to 2022 in a large public healthcare system in New York City. Patients with SSIs were identified, and controlling for nine variables, propensity score matching was used to create a matched control group without SSIs. Prophylactic regimens were compared between the matched groups with and without SSIs. Also, for the patients with SSIs, the impact of the prophylactic regimen on the subsequent pathogens involved the infection was examined. Results: A total of 275 patients with SSIs were compared to a matched cohort without SSIs. The prophylactic regimens were extremely similar between the SSI and control groups. Among the patients who developed SSIs, more patients who received cefoxitin had emergence of select cephalosporin-resistant Enterobacterales and Bacteroides spp. when compared with those who received β-lactam-β-lactamase inhibitors. Conclusions: The distribution of surgical prophylaxis regimens was remarkably similar between patients developing serious SSIs and a closely matched cohort that did not develop an SSI. However, given the downstream effects of more resistant and anaerobic flora should an infection develop, use of cefoxitin should be re-evaluated as a prophylactic agent.

Are persons living with diagnosed HIV capable of mounting a strong inflammatory response to the new coronavirus? Int J STD AIDS 2023; 34:978-983. [PMID: 37498157 PMCID: PMC10375225 DOI: 10.1177/09564624231191814] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 07/17/2023] [Indexed: 07/28/2023]
Abstract
BACKGROUND The impact of COVID-19 on persons living with diagnosed HIV (PLWDH) remains incompletely understood. It's unclear whether an impaired immune system offers protection against mounting cytokine storm. METHODS Retrospective matched cohort study of COVID-19 hospitalized individuals in New York State (NYS). Medical records were abstracted and analyzed for 853 PLWDH hospitalized with COVID-19 in NYS and 1621 HIV-negative controls. Preexisting comorbidities and inflammatory markers measured within 24 h of hospital admission were abstracted. RESULTS PLWDH were significantly less likely to have elevated inflammatory markers compared to matched controls. Elevated WBC occurred in 23.3% of PLWDH vs 30.1% of controls (p = .0002), elevated CRP in 37.4% of PLWDH vs 43.2% of controls (p = .03), elevated ferritin in 73.4% of PLWDH vs 78.9% of controls (p = .004). There was an inverse but not statistically significant relationship between the frequency of elevated inflammatory markers and HIV disease stage, with greatest percent of PLWDH with elevated WBC, LDH, CRP, and ferritin among PLWDH with HIV disease stage 1. CONCLUSION PLWDH had lower inflammatory marker elevation during COVID-19 infection compared to matched controls. PLWDH with low CD4 were less likely to mount a cytokine storm in the setting of impaired immune function.

Abstract
Controlling the spread of carbapenem-resistant Enterobacterales is a global priority. Using National Healthcare Safety Network data, we characterized the changing epidemiology of carbapenem-resistant Klebsiella pneumoniae (CRKP) in a large public health system in New York, New York, USA. During 2016-2020, CRKP cases declined; however, during 2021-June 2022, a notable increase occurred. Of 509 cases, 262 (51%) were considered community-onset, including 149 in patients who were living at home. Of 182 isolates with proven or presumptive (ceftazidime/avibactam susceptible) enzymes, 143 were serine carbapenemases; most confirmed cases were K. pneumoniae carbapenemase. The remaining 39 cases were proven or presumptive metallo-β-lactamases; all confirmed cases were New Delhi metallo-β-lactamases. After 2020, a marked increase occurred in the percentage of isolates possessing metallo-β-lactamases. Most patients with metallo-β-lactamases originated from long-term care facilities. An aggressive and universal program involving surveillance and isolation will be needed to control the spread of CRKP in the city of New York.

Abstract
Background Tocilizumab and baricitinib are immunomodulators that have been repurposed for the treatment of coronavirus disease 2019 (COVID-19). Whether one medication should be preferred over the other has not been established. Methods This multicenter retrospective cohort study comprised hospitalized patients with COVID-19 who received either tocilizumab or baricitinib. The primary outcome was improvement in respiratory status (at least 1-point reduction on the respiratory ordinal scale) at day 7 and up to day 28. Secondary outcomes included mortality, disposition, deep vein thrombosis, pulmonary embolism, or positive blood culture. Outcomes were stratified by baseline respiratory status and variant-predominating periods. Results were reported for the overall and propensity-matched cohorts. Results A total of 921 patients received tocilizumab and 638 received baricitinib. The propensity-matched cohort included 597 patients in each group. At day 7 in the overall and propensity-matched cohorts, significantly more patients had improvement in respiratory status in the baricitinib group. These improvements were seen in patients requiring supplemental oxygen and noninvasive ventilation/high-flow oxygen but not in patients requiring mechanical ventilation. Favorable outcomes with baricitinib were observed during the Alpha and Omicron periods. By day 28, there were no differences in the changes of respiratory status for the treatment groups in either cohort. Also, no differences were seen in mortality, disposition, development of deep vein thrombosis/pulmonary embolism, or bloodstream infections. Conclusions Baricitinib treatment was associated with more favorable respiratory improvement at day 7 when compared with tocilizumab, but no differences were observed up to day 28.

Abstract
During the pandemic, the rate of healthcare facility-onset methicillin-resistant Staphylococcus aureus (MRSA) bacteremia was 5 times greater in patients admitted with coronavirus disease 2019 (COVID-19). The presence of central lines and mechanical ventilation likely contribute to this increased rate. The number of central-line-associated bacteremia cases may be underestimated in patients with COVID-19.

Abstract
Contrary to national reports, rates of healthcare facility-onset Clostridioides difficile infection across an 11-hospital system rose after the spring of 2020, when New York City was the epicenter for the COVID-19 pandemic. Antibiotic pressure from an escalation in cephalosporin usage correlated with this increase. The majority of cases of Clostridioides difficile were in patients without COVID-19, suggesting the pandemic has adversely impacted the healthcare of other inpatients.

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.

Investigating microbial dynamics and potential advantages of anaerobic co-digestion of cheese whey and poultry slaughterhouse wastewaters. Sci Rep 2022; 12:10529.

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.

Appraisal of synthetic cationic Gemini surfactants as highly efficient inhibitors for carbon steel in the acidization of oil and gas wells: an experimental and computational approach. RSC Adv 2022; 12:17050-17064.

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
Reports conflict on how HIV infection influences the clinical course of COVID-19. The New York City (NYC) public hospital system provides care for over 14,000 people with HIV, was central in responding to the COVID-19 pandemic, and is therefore in a unique position to evaluate the intersection of these concurrent infections. Retrospective chart review of patients presenting to NYC Health and Hospitals (NYC H+H) diagnosed with COVID-19 infection from March 1, 2020, through April 28, 2020, compared people living with HIV (PLWH) and a propensity-matched (PM) control group of patients without HIV to evaluate associations between HIV status and COVID-19 outcomes. Two hundred thirty-four PLWH presented for COVID-19 testing and 110 (47%) were diagnosed with COVID-19. Among 17,413 patients with COVID-19 and without HIV, 1:n nearest neighbor propensity score matching identified 194 patients matched on age, sex, race, and any comorbidity. In the sample with COVID-19 (N = 304), PLWH (9.1%) had lower rates of mortality than controls [19.1%; PM odds ratio (PM-OR): 0.41, 95% confidence interval (CI): 0.19-0.86]. Among hospitalized COVID-19 patients (N = 179), HIV infection was associated with lower rates of mechanical ventilation (PM-OR: 0.31, 95% CI: 0.11-0.84) and mortality (PM-OR: 0.40, 95% CI: 0. 17-0.95). In the extended pandemic period through April 2021, aggregate data by HIV status suggested elevated hospitalization and mortality rates in PLWH versus people without HIV. These results suggest that the direct biological impacts of the HIV virus do not negatively influence COVID-19-related outcomes when controlling for comorbidity and demographic variables.

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
BACKGROUND The release of pro-inflammatory cytokines, resulting in cytokine storm syndrome, contributes to the morbidity and mortality associated with COVID-19 disease. This study aimed to compare the effects of intravenous (IV) and subcutaneous (SC) tocilizumab, an IL-6 receptor antagonist, on respiratory parameters and clinical outcome in patients with COVID 19. METHODS We performed a retrospective cohort study of hospitalized patients with COVID-19 treated with either IV or SC tocilizumab from March 26, 2020, to May 18, 2020. Respiratory parameters seven days after receiving tocilizumab therapy were compared to baseline measurements. All patients were assessed until discharged from the hospital. RESULTS Tocilizumab was administered to 125 patients: 65 received IV, and 60 received SC therapy. At day seven, 52% of the IV group patients demonstrated improvement in respiratory parameters, compared to 28% in the SC group (P = 0.01). Mortality rates at days seven and 28 were 15% and 37%, respectively, in the IV group and 17% and 50%, respectively, in the SC group (PNS). The in-hospital mortality rate was 38% for the IV group versus 57% for the SC group (P = 0.04). More than 90% of patients in each group received corticosteroids; however, significantly more patients received convalescent plasma in the IV group. CONCLUSIONS At the doses used in this study, IV tocilizumab is preferred over SC therapy to treat cytokine storm syndrome due to COVID-19.

Abstract
A Bangladeshi patient with prior travel to Saudi Arabia was hospitalized in the United States for a presumptive liver abscess. Praziquantel was administered following a positive Schistosoma antibody test. Ten days later, a subadult worm migrated to the skin surface and was identified morphologically as Gnathostoma spinigerum. This case highlights the challenges of gnathostomiasis diagnosis, raising questions on potential serologic cross-reactivity and the possible role of praziquantel in stimulating outward migration of Gnathostoma larvae/subadults.

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.
