    Abstract Purpose: Evaluate trends in mortality due to acute epiglottitis before and after adoption of Haemophilus influenza Type b vaccination (Hib) in pediatric and adult populations.
    Materials and methods: Patients who died from acute epiglottis from 1979 to 2017 identified using National Vital Statistics System. Mortality rates calculated using age-adjusted US census data expressed in rate per 100,000 individuals. Trends analyzed using the National Cancer Institute Joinpoint Regression Program (version 4.7.0; Bethesda, Maryland).
    Results: 1187 epiglottitis-related deaths were identified over thirty-nine years. Total deaths decreased from 65 in 1979 to 15 in 2017. Adult deaths accounted for 63.5% and decreased from 0.015 per 100,000 individuals (24 deaths) in 1979 to 0.006 per 100,000 individuals (14 deaths) in 2017. Best fitting log-liner regression model showed APC of -3.5% (95% CI, -4.2 to -2.7%) from 1979 to 2017. Pediatric and adolescent deaths accounted for 443 (37.3%) deaths, decreasing from 0.064 per 100,000 individuals (41 deaths) in 1979 to 0.001 per 100,000 individuals (1 death) in 2017. APC was -11.1% (95% CI, -13.8% to -8.3%) in 1979 to 1990; 46.5% (95% CI, -16.6% to 157.3%) in 1990 to 1993; -61.6% (95% CI, -88% to 23%) in 1993 to 1996; and 1.1% (95% CI, -2.4% to 4.7%) in 1996 to 2017.
    Conclusions: Mortality from acute epiglottitis decreased after widespread adoption of Hib vaccination in the US. Adults are now more likely than children to die of acute epiglottitis. Further research including multi-institutional cohort studies must be done to elucidate causative factors contributing to remaining cases of mortality.

    Abstract The paper examines the performance and the challenges faced by SMEs in Oman during Covid-19. The data was collected through primary and secondary sources. A questionnaire of 100 respondents was used. Descriptive analysis and chi-squared test have been employed in the data analysis. The main findings of the study showed despite the adverse effect of the pandame, the SMEs in Oman have performed well and indicated a resilient and adaptable strategy to cope wth the virus. The reason for this could be attributed to their ability to quickly transition to remote work and online operations. During such a challenging period, some businesses managed to thrive due to their ability to identify opportunities and leverage them. Moreover, the study revealed that financial stability and preparedness are key to navigating the pandemic's uncertainties, as businesses focus on risk management, budget planning, and saving money. In response to unexpected disruptions, businesses have become more cautious and strategic in their financial decisions. SME resilience against future crises is enhanced as a result of SMEs adopting more prudent financial practices. The key challenges faced by SMEs during Covid-19 included delivery delays, reduced income for consumers, and regulation changes. The SMEs in Oman devised severalrisk management strategies, such as maintaining backup plans and setting aside funds, reflect a forward-thinking approach. The findings indicate that businesses in Oman are actively seeking ways to minimize disruptions to their operations and mitigate potential risks. Long-term resilience can be built by such strategic thinking.

    Abstract The coronavirus disease 19 (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) prompted the development of diagnostic and therapeutic frameworks for timely containment of this pandemic. Here, we utilized our non-conventional computational algorithm, InSiPS, to rapidly design and experimentally validate peptides that bind to SARS-CoV-2 spike (S) surface protein. We previously showed that this method can be used to develop peptides against yeast proteins, however, the applicability of this method to design peptides against other proteins has not been investigated. In the current study, we demonstrate that two sets of peptides developed using InSiPS method can detect purified SARS-CoV-2 S protein via ELISA and Surface Plasmon Resonance (SPR) approaches, suggesting the utility of our strategy in real time COVID-19 diagnostics. Mass spectrometry-based salivary peptidomics shortlist top SARS-CoV-2 peptides detected in COVID-19 patients' saliva, rendering them attractive SARS-CoV-2 diagnostic targets that, when subjected to our computational platform, can streamline the development of potent peptide diagnostics of SARS-CoV-2 variants of concern. Our approach can be rapidly implicated in diagnosing other communicable diseases of immediate threat.

    Abstract For the development of selective and sensitive chemical sensors, we have developed a new family of poly(ether-phosphoramide) polymers. These polymers were obtained with satisfactory yields by nucleophilic aromatic polycondensation using isosorbide as green resources, and bisphenol A with two novel difluoro phosphinothioic amide monomers. Unprecedented, the thiophosphorylated aminoheterocycles monomers, functionalized with two heterocyclic amine, N-methylpiperazine and morpholine were successfully obtained by nucleophilic substitution reaction of P(S)-Cl compound. The resulting polymers were characterized by different analytical techniques (NMR, MALDI-ToF MS, GPC, DSC, and ATG). The resulting partially green polymers, having tertiary phosphine sulfide with P-N side chain functionalities along the main chain of polymers are the sensitive film at the surface of a gold electrode for the impedimetric detection of Cd, Ni, Pb and Hg. The bio-based poly(ether-phosphoramide) functionalized with N-methylpiperazine modified sensor showed better analytical performance than petrochemical based polymers for the detection of Ni

    Abstract Objective: To compare the outcomes of transapical transcatheter aortic valve replacement (TA-TAVR) and surgical aortic valve replacement (SAVR) using a large US population sample.
    Methods: The U.S. National Inpatient Sample was queried for all patients who underwent TA-TAVR or SAVR during the years 2016-2017. The primary outcome was all-cause in-hospital mortality. Secondary outcomes were in-hospital stroke, pericardiocentesis, pacemaker insertion, mechanical ventilation, vascular complications, major bleeding, acute kidney injury, length of stay, and cost of hospitalization. Outcomes were modeled using multi-variable logistic regression for binary outcomes and generalized linear models for continuous outcomes.
    Results: A total of 1560 TA-TAVR and 44,280 SAVR patients were included. Patients who underwent TA-TAVR were older and frailer. Compared to SAVR, TA-TAVR correlated with a higher mortality (4.5%
    Conclusion: The risk-adjusted analysis showed that TA-TAVR has no advantage over SAVR except for patients with chronic lung disease where TA-TAVR has higher mortality.

    Abstract The ongoing COVID-19 pandemic has highlighted the immediate need for the development of antiviral therapeutics targeting different stages of the SARS-CoV-2 life cycle. We developed a bioluminescence-based bioreporter to interrogate the interaction between the SARS-CoV-2 viral spike (S) protein and its host entry receptor, angiotensin-converting enzyme 2 (ACE2). The bioreporter assay is based on a nanoluciferase complementation reporter, composed of two subunits, large BiT and small BiT, fused to the S receptor-binding domain (RBD) of the SARS-CoV-2 S protein and ACE2 ectodomain, respectively. Using this bioreporter, we uncovered critical host and viral determinants of the interaction, including a role for glycosylation of asparagine residues within the RBD in mediating successful viral entry. We also demonstrate the importance of N-linked glycosylation to the RBD's antigenicity and immunogenicity. Our study demonstrates the versatility of our bioreporter in mapping key residues mediating viral entry as well as screening inhibitors of the ACE2-RBD interaction. Our findings point toward targeting RBD glycosylation for therapeutic and vaccine strategies against SARS-CoV-2.

Box 330127, Zarqa, 13133, Jordan, Tel +962-5-3903333, Email hanagh@yahoo.comBackground: Medical students’ involvement in patients’ care varies according to patient’s willingness, as some might consider it a privacy invasion. Thus, exploring patients’ perceptions and attitudes towards this interaction should be thoroughly investigated, to better understand it and to provide evidence-based data for improving the training of future doctors.Methods: A cross-sectional study was conducted at Jordan University Hospital. A questionnaire was answered by 420 patients from the out-patients’ clinics.Results: Of the patients interviewed, 94% were aware that they were in a teaching hospital, 92% approved the presence of medical students during their consultation and 80% accepted to be observed and examined by medical students in the presence of a senior doctor. However, this decreased to 30.5% if there was no senior doctor. Almost 83% of the patients believed that their consent should be obtained first. However, only 58% of them indicated that the student asked for consent prior to interacting with them. Patients who were more likely to approve the existence of medical students during consultation and allow students to perform procedures on them, respectively, were those who were asked for consent by students (P = 0.001 and P = ...
