RHAMNETIN IS A BETTER INHIBITOR OF SARS-COV-2 2’-O-METHYLTRANSFERASE THAN DOLUTEGRAVIR: A COMPUTATIONAL PREDICTION

Background: The 2’-O-methyltransferase is responsible for the capping of SARS-CoV-2 mRNA and consequently the evasion of the host’s immune system. This study aims at identifying prospective natural inhibitors of the active site of SARS-CoV-2 2’O-methyltransferase (2’-OMT) through an in silico approach. Materials and Method: The target was docked against a library of natural compounds obtained from edible African plants using PyRx - virtual screening software. The antiviral agent, Dolutegravir which has a binding affinity score of -8.5 kcal mol−1 with the SARS-CoV-2 2’-OMT was used as a standard. Compounds were screened for bioavailability through the SWISSADME web server using their molecular descriptors. Screenings for pharmacokinetic properties and bioactivity were performed with PKCSM and Molinspiration web servers respectively. The PLIP and Fpocket webservers were used for the binding site analyses. The Galaxy webserver was used for simulating the time-resolved motions of the apo and holo forms of the target while the MDWeb web server was used for the analyses of the trajectory data. Results: The Root-Mean-Square-Deviation (RMSD) induced by Rhamnetin is 1.656A0 as compared to Dolutegravir (1.579A0). The average B-factor induced by Rhamnetin is 113.75 while for Dolutegravir is 78.87; the Root-Mean-Square-Fluctuation (RMSF) for Rhamnetin is 0.75 and for Dolutegravir is 0.67. Also at the active site, Rhamnetin also has a binding affinity score of -9.5 kcal mol−1 and forms 7 hydrogen bonds as compared to Dolutegravir which has -8.5 kcal mol−1 and forms 4 hydrogen bonds respectively. Conclusion: Rhamnetin showed better inhibitory activity at the target’s active site than Dolutegravir

Phytotoxicity assessment of compost-type Biofertilizer using Co-Composting and Post Composting Fortification Methods

Phytotoxicity sets in when immature and not well prepared compost is used on the farm. This research work was targeted at preparing compost from different organic material combination and assessing the phytotoxic effects of different compost combinations. Compost of organic materials was prepared and fortified giving the following combinations: PM+RB+BM+GL, PM+SD+BM+GL, PM+RB+GL and PM+SD+GL. The carbon and nitrogen sources were combined using 1:3 ratio, the combination was sprinkled with water. Data such as ambient temperature of each pile was taken daily, while pH and electrical conductivity tests were taken on samples fortnightly. On maturation of the compost, post fortification technique was carried out hereby creating two more combinations tagged PM+RB+GL (BMP) and PM+SD+GL (BMP). The six compost combinations were tested in terms of their germination percentage, after which data on germination %, relative germination %, root length, weight gained and germination index were taken and analyzed using anova, their mean were separated using Duncan Multiple Range Test (DMRT) at 5% probability level.Fortification with phosphorus source at the onset of composting promoted plant growth hence no sign of phytotoxicity while fortification with phosphorus source after maturation increased phytotoxicity.

Nursing in the Orthogeriatric Setting

The speciality of orthogeriatric nursing has only recently emerged and is evolving rapidly. The recognition of the global burden of fragility fractures is growing and the recent call to action issued by the Fragility Fracture Network [1] has created momentum and further strengthened an expanding international network of nurses who continue to champion the development of this role. This chapter explores the key nursing roles and interventions relating to orthogeriatric nursing care. It considers how nursing care quality, focused on nurse-specific indicators, skill, education, leadership and resources, can positively impact on patient outcomes in all phases of the care journey. The central nursing role in preventing and managing complications is specifically outlined

Can emergency nurses safely and effectively insert fascia iliaca blocks in patients with a fractured neck of femur? A prospective cohort study in an Australian emergency department

Aims and objectives To compare the effectiveness and safety of ultrasound-guided fascia iliaca block (FIB) insertion in patients with fractured neck of femur by trained emergency nurses with insertion by doctors. Background The FIB is an effective and safe form of analgesia for patients with hip fracture presenting to the emergency department (ED). While it has traditionally been inserted by medical doctors, no evidence exists comparing the effectiveness and safety of FIB insertion by nurses compared with doctors. Design A prospective cohort study. Methods The study was conducted in an Australian metropolitan ED. Patients admitted to the ED with suspected or confirmed fractured neck of femur had a FIB inserted under ultrasound guidance by either a trained emergency nurse or doctor. A retrospective medical record audit was undertaken of consecutive ED patients presenting between January 2013–December 2017. Reporting of this study followed the Strengthening the Reporting of Observational Studies in Epidemiology guidelines for cohort studies. Results Of the 472 patients eligible for a FIB, 322 (68%) had one inserted. A majority were inserted by doctors (n = 207, 64.3%) with 22.4% (n = 72) by nurses and in 13.3% (n = 43) of patients the clinician was not documented. There were no differences between the nurse-inserted and doctor-inserted groups for mean pain scores 1 hr post-FIB insertion; clinically significant reduction (≥30%) in pain score 1 hr post-FIB insertion; pain score 4 hr post-FIB insertion; delirium incidence; opioid use post-FIB insertion; or time to FIB insertion. No adverse events were identified in either group. Conclusion Insertion of FIBs by trained emergency nurses is as effective and safe as insertion by doctors in patients with fractured neck of femur in the ED. Senior emergency nurses should routinely be inserting FIB as a form of analgesia for patients with hip fracture. Relevance to clinical practice Our study showed trained emergency nurses can safely and effectively insert fascia iliaca blocks in patients with hip fractures. Pain was significantly reduced in a majority of patients with no reported complications. Emergency nurses should be trained to insert fascia iliaca blocks in patients with hip fractures
