Abstract
Abstract
Background
Although health-care workers are trained to provide basic, intermediate, or advanced life support from a technical perspective, working as a team is a more complex process in acute situations. Responding to the emergency buzzer from the ward staff, and before the medical emergency arrival, could be sometimes chaotic. This may result in deficient initial management or missing basic measures.
Context
The “ABC Team” is a project, aimed to enhance the health care providers' skills in dealing with emergency situations, within the surgical ward, in an organized manner.
Innovation
Guidance for the staff was created to identify an exact job for every health care provider in the shift by assigning one job/person. Over a period of 5 months, individual training was given to the ward staff. Roles are assigned in the shift handover and A, B, C, D cards (to be attached to the ID) were printed with the information needed for a quick response. Simulation training sessions were organized before launching the project.
Implications
Streamline patient care significantly improved and ABCD assessment time is broken down to half. Pre and post project surveys showed approximately 80% of staff are now satisfied, confident and clear with their role in the emergency event.

Abstract
Abstract
Background
There is limited evidence on the differences in procedural outcomes between sexes after de novo cardiac implantable electronic device implantation (CIED). Furthermore, it is unclear whether any sex-based disparities have changed over the years.
Purpose
To compare procedural outcomes of de novo CIED implantation between sexes and study the trends of these outcomes over a 11-year period in a nationally representative sample.
Methods
Using the National Inpatient Sample, all hospitalisations between 2004 and 2014 for de novo CIED implantation were included, stratified by sex. Multivariable logistic regression was performed to 1) examine the association between sex and in-hospital complications of CIED implantation, expressed as odds ratios (OR) with 95% confidence intervals (CI), and 2) analyse trends of in-hospital outcomes by assessing the interaction term between time (years) and sex as covariates.
Results
Out of 2,815,613 hospitalisations for de novo CIED implantation, 41.9% were performed on women. Women were associated with increased adjusted odds of major adverse cardiovascular events (composite of mortality, thoracic and cardiac complications; OR 1.17 95% CI 1.16, 1.19), procedure-related bleeding (OR 1.13 95% CI 1.12, 1.15), and local complications (thoracic: OR 1.42 95% CI 1.40, 1.44, cardiac: OR 1.44 95% CI 1.38, 1.50). (p<0.001 for all) Notably, there was no difference in odds of all-cause mortality between sexes (OR women: 0.96 95% CI 0.94, 1.00). The odds of adverse complications in the overall CIED cohort were persistently raised in women throughout the study period, whereas similar odds of all-cause mortality across the sexes were observed throughout the study period (see Figure).
Conclusion
In a national cohort of CIED implantations we demonstrate that women are at a persistently higher risk of procedure-related adverse events other than mortality compared to men. This trend is concerning and warrants further work on procedural techniques to neutralise these sex disparities.

Abstract
Abstract
Background
Postoperative acute ischemic stroke (AIS) is a catastrophic complication of coronary artery bypass grafting (CABG). There is limited data on the incidence and outcomes of AIS complicating CABG in the contemporary era, and whether these have changed over the years.
Purpose
To study the incidence and outcomes of postoperative AIS in a nationally representative cohort of CABG procedures over a 12-year period and examine predictors of AIS in patients undergoing CABG.
Methods
The National Inpatient Sample was used to identify all adult patients (>18 years old) who underwent CABG in the United States between January 2004 and September 2015. Multivariable logistic regression was performed to examine the associations between postoperative AIS and in-hospital mortality and identify predictors of AIS after CABG, expressed as odds ratios (OR) with corresponding 95% confidence intervals (CI).
Results
A total of 2,569,597 CABG operations were analysed. The incidence of postoperative AIS was 1.8% (n=47,279) in the overall cohort increasing from 1.2% in 2004 to 2.3% in 2015 (p<0.001). Significantly higher rates of AIS were observed amongst patients with atrial fibrillation (AF) and those undergoing non-elective or concomitant valve operations over the study period (see Figure). Patient risk profiles increased over time in both AIS and no-AIS cohorts, with higher Charlson comorbidity scores observed amongst AIS patients. AIS was independently associated with increased odds of in-hospital mortality (OR 3.03, 95% CI 2.93, 3.13) and prolonged hospital stay (∼6 more days) and a higher hospitalisation cost (∼$80,000 more) (p<0.001 for all). Several factors were predictors of AIS including age>60 years (61–70 years: OR 1.33, 95% CI 1.29, 1.37; 71–80 years: OR 1.49, 95% CI 1.44, 1.54; >80 years: OR 1.42, 95% CI 1.37, 1.48), female sex (OR 1.33, 95% CI 1.31, 1.36) and AF (OR 1.14 95% CI 1.12, 1.16) (p<0.001 for all). In contrast, on-pump CABG was not an independent predictor of stroke (OR 1.01, 95% CI 0.94, 1.09) (p=0.784).
Conclusion
In this nationally representative study, we have shown that the rates of postoperative stroke following CABG have increased over time in line with complexity of patient risk profiles. The present findings emphasise the need for further work on strategies to reduce the risk of postoperative stroke after CABG.

Abstract
Abstract
Background
People with osteoarthritis (OA) have an increased risk of cardiovascular disease, including acute myocardial infarction (AMI). Despite OA being the most common joint condition and the fastest increasing major health condition, there is limited information on the management strategies and subsequent outcomes of OA patients presenting with AMI.
Purpose
To describe the association between OA and invasive management strategies (including coronary angiography (CA), percutaneous coronary intervention (PCI), and coronary artery bypass grafting (CABG)) and clinical outcomes.
Methods
We analysed all hospitalisations for AMI between 2004 and 2015 recorded in the National Inpatient Sample (NIS), the largest inpatient electronic health record database in the United States. The proportion of patients receiving CA, PCI, and CABG were compared between patients with and without OA, as were the proportions of in-hospital adverse events including major acute cardiovascular and cerebrovascular events (MACCE; composite of mortality, cardiac complications and acute stroke), in-hospital mortality, stroke, and major bleeding. Multivariate logistic regression modelling with adjustment for potential confounders (demographics, medical history, and comorbidities) was performed to examine associations between OA and in-hospital clinical outcomes; results are expressed as adjusted odds ratios (AdjOR) with 95% confidence intervals (95% CI).
Results
A total of 6,561,940 people were hospitalised for AMI between January 2004 and September 2015, of which 444,217 (6.8%) had a concurrent diagnosis of OA. On average, those with OA were older (median: 77 vs. 67 years), more likely to be female (55.7% vs. 38.6%), and less likely to receive CA (55.3% vs. 65.2%), PCI (33.3% vs. 43.6%), and CABG (7.4% vs. 8.5%) (Figure 1A, p<0.001 for all). After adjustment for confounders, OA was associated with a lower likelihood of receiving CA (AdjOR 0.89; 95% CI 0.87, 0.90), PCI (0.85; 0.84, 0.87), and CABG (0.92; 0.90, 0.94). With reference to outcomes, OA was associated with lower likelihood of in-hospital adverse events (MACCE: AdjOR 0.71; 95% CI 0.69, 0.72; in-hospital mortality: 0.69; 0.67, 0.71; stroke: 0.81; 0.77, 0.85; and major bleeding: 0.73; 0.70, 0.75) (Figure 1B, p<0.001 for all).
Conclusion
In a national cohort of AMI hospitalisations, patients with OA were less likely to receive invasive management compared to those without OA. However, they were also less likely to experience adverse events. Further work is required to investigate treatment disparities in this increasingly prevalent patient group when presenting with AMI.

Abstract
Abstract
Background
Severe mental illness (SMI) is associated with an increased risk of cardiovascular disease and mortality. However, it is unclear whether SMI patients are just as likely to receive guideline-recommended therapy for AMI as those without mental illness.
Purpose
To examine national-level estimates of the prevalence, management strategies and in-hospital clinical outcomes of SMI patients presenting with AMI.
Methods
All AMI hospitalisations from the United States National Inpatient Sample were included, stratified by mental health status in to 5 groups: no-SMI, Schizophrenia, “Other non-organic psychoses” (ONOP), Bipolar Disorder and Major Depression. Multivariable logistic regression modelling was performed to examine the association between SMI subtypes and receipt of invasive management and subsequent in-hospital clinical outcomes, expressed as adjusted odds ratios (aOR) and 95% confidence intervals (CI).
Results
Out of 6,968,777 AMI hospitalisations between 2004 and 2014, a total of 439,544 (6.5%) had an SMI diagnosis. The prevalence of SMI amongst the ACS population doubled over the study period (from 4.5% in 2004 to 9.5% in 2014), primarily due to an increase in Major Depression and Bipolar Disorder diagnoses. All SMI subtypes were less likely to receive coronary angiography and PCI, with the Schizophrenia group being at least odds of either procedure (aOR 0.46 95% CI 0.45, 0.48 and aOR 0.57 95% CI 0.55, 0.59, respectively). Although patients with Schizophrenia and ONOP experienced higher crude rates of in-hospital mortality and stroke compared to those without SMI, only Schizophrenia patients were associated with increased odds of mortality (aOR 1.10 95% CI 1.04, 1.16), while ONOP were the only group at increased odds of stroke (aOR 1.53 95% CI 1.42,1.65) following multivariate adjustment. Patients with ONOP were the only group associated with increased odds of in-hospital bleeding compared to those without SMI (aOR 1.11 95% CI 1.04,1.17).
Conclusion
Patients with SMI are less likely to receive invasive management for AMI, with women and schizophrenia diagnosis being the strongest predictors of conservative management. Schizophrenia and “other non-organic psychoses” are the only SMI subtypes associated with adverse clinical outcomes after AMI. A multidisciplinary approach between psychiatrists and cardiologists could improve outcomes of this high-risk population.

Abstract
Abstract
Introduction/Objective
In the exploration of an alternative source, optimum and numerous solvents with different percentage were exploited to extract Taxol from plant palm branche. The fungal endophytes producing secondary metabolites that are effective against the human infections have fascinated many researchers across the world.
Among these, the exploration for novel cancer therapeutic agents is of countless reputation due to upsurge in the number of cancer deaths, high worth of the drugs and the side effects concomitant with cancer treatments.
Accordingly, in the current study, an endophytic fungal strain was isolated from its host plant palm branche and identified as Alternaria Alternata based on its morphological features and internal transcribed spacer sequence analysis.
Methods
Firstly, palm branche were collected for the isolation of endophytic fungi. The samples were placed on PDA plates and after 72 h, the mycelium produced were isolated and sub-cultured. Secondly, further analysis for the presence of Taxol by using chromatographic and spectrometric techniques. Illustratively, ethanol or acetone and 50% and 20% of ethanol. Then, the residues were dissolved in 5 ml of methanol and filtered. By using the internal standard, the resulting solution was subjected to the HPLC to determine the extraction efficiencies of tested solvents. Finally, filtrate was also subjected to the LC-MS – ESI using water/acetonitrile (10/90) as mobile phase to identify the authenticity of Taxol
Results
HPLC analysis revealed that Taxol could be quantified by UV detection using standard curve. Furthermore, the standard curve covering the concentration was linear (r2= 0.9992) and CV% ranged from 0.52 to 15.36. The peaks of fraction 5 obtained by HPLC analysis were quite similar to that of standard taxol confirming the presence of taxol. A parent ion peak of m/z 851.85 was observed in the LC–ESI–MS spectrum which was similar to paclitaxel with reported m/z of 854 [M+H] + ion. A. Alternata produced about 113.193 mg/L taxol as quantified through HPLC
Conclusion
we are recording for the first time the production of taxol by an endophytic fungus Alternaria Alternata. In a final word, present study results advocate that the endophytic fungus A.Alternata aids as a potential source for the production of taxol isolated from Palm branche plant

Abstract
BACKGROUND Organ transplant recipients are vulnerable to multiple infectious agents and in a world with a circulating SARS-CoV-2 virus, it would be expected that patients who are immunosuppressed would have higher mortality. OBJECTIVE To determine the COVID-19 mortality in transplant recipients. METHODS We conducted a search in PubMed and Google scholar databases using the keywords for COVID-19 and transplantation. All related studies between January 1, 2020 and May 7, 2020 were reviewed. All relevant published articles related to COVID-19 in transplant recipients were included. RESULTS 46 articles were included; they studied a total of 320 transplant patients-220 kidney transplant recipients, 42 liver, 19 heart, 22 lung, 8 HSCT, and 9 dual organ transplant recipients. The overall mortality rate was 20% and was variable among different organs and different countries. 65 transplant recipients died of complications attributable to COVID-19; 33 were males (15% of males in this cohort), 8 females (8% of females in this cohort), and 24 whose sex was not determined. They had a median age of 66 (range: 32-87) years. The median transplantation duration was 8 years (range: 30 days to 20 years). The most frequent comorbidity reported was hypertensions followed by diabetes mellitus, obesity, malignancy, ischemic heart disease, and chronic obstructive pulmonary disease. The most frequent cause of death reported was acute respiratory distress syndrome. CONCLUSION Transplant recipients in our cohort had a high mortality rate. However, outcomes were not the same in different countries based on outbreak settings. Mortality was noted in elder patients with comorbidities.

Abstract
Background A global rise in multidrug-resistant (MDR) nosocomial infections has led to a significant increase in morbidity and mortality. MDR Gram-negative bacteria (GNB) are recognised for rapidly developing drug resistance. Despite Pseudomonas aeruginosa being the second most common GNB isolated from healthcare associated infections, the magnitude of MDR P. aeruginosa (MDR-PA) has not been evaluated in Qatar. Aim To assess the prevalence and antimicrobial susceptibility patterns of MDR-PA from 5 major hospitals in Qatar. Methods A total of 2533 P. aeruginosa clinical isolates were collected over a one-year period. MDR-PA was defined as resistance to at least one agent of ≥ 3 antibiotic classes. Clinical and demographic data were collected prospectively. Findings The overall prevalence of MDR-PA isolates was 8.1% (205/2533); the majority of isolates were from patients exposed to antibiotics during 90 days prior to isolation (85.4 %, 177/205), and the infections were mainly hospital-acquired (95.1%, 195/205) with only 4.9% from the community. The majority of MDR-PA isolates were resistant to cefepime (96.6%, 198/205), ciprofloxacin, piperacillin/tazobactam (91%, 186/205), and meropenem (90%, 184/205). Patient comorbidities with MDR-PA were diabetes mellitus (47.3%, n=97), malignancy (17.1%, n=35), end-stage renal disease (13.7%, n=28) and heart failure (10.7%, n=22). Conclusion There was a significant prevalence of MDR-PA in Qatar, primarily from healthcare facilities and associated with prior antibiotic treatment. There was an alarming level of antimicrobial resistance to carbapenems. Our results are part of a national surveillance of MDR to establish effective containment plans.

Abstract
Uropathogenic E. coli (UPEC) is the major etiological agent of urinary tract infections. The objectives of this study were to evaluate E. coli isolates from these patients for the phenotypic pattern of antibiotic resistance and to detect the genes responsible for virulence namely fimH, hlyA and usp. A total of 110 E. coli isolates were studied and 30 antibiotics were applied for susceptibility testing. PCR detection of the genes fimH, hlyA and usp was done followed by sequencing and phylogenetic analysis. The results showed that the isolates were highly resistant to cephalaxin (100%) and cephradine (100%) but displayed high sensitivity to amikacin (96.27%), Imipenem (92.63%) and Meropenem (92.63%). The prevalence of fimH, hlyA and usp was 86%, 83% and 16%, respectively. The sequencing showed 99% similarity with previously reported sequences in NCBI GenBank database. The co-existence of multiple drug-resistant bodies and virulent genes has important implications for the treatment of patients with urinary tract infection. This study provides information about treating drug-resistant E. coli and the relationship of virulent genes with phenotypic resistance patterns.
