Basic clinical characteristics and hospital outcomes of acute coronary syndrome patients - Sudan

Background: There are Variation in the presentation of the acute coronary syndrome between countries. The present study aimed to investigate the basic clinical characteristics and in-hospital outcomes among acute coronary syndrome patients in the Sudan.Material and Methods: A cross-sectional comparative study conducted among 202 consecutive acute coronary syndrome patients at a reference coronary care unit in Omdurman Teaching Hospital between July 2014 and August 2015. Participants signed a written informed consent, and then a case report form was filled. Information collected include vascular risk factors, vital signs, echocardiographic findings, and in Hospital complications. The local ethical committee approved the research, and the chi-square test was used to compare ST-segment Elevation (STSEACS) and None ST-Segment Elevation Acute coronary syndrome (NSTSEACS).Results: (out of 202 women (53.75%) in (NSEACS) P = 0.009). Prior myocardial infarction, hypertension, diabetes mellitus, and, smoking were evident in 19.8%. 53.%, 30.2%, and 16.6% of acute coronary syndrome respectively, 97% of patients presented with chest pain, 54% presented to the hospital after 24 hours. Hypotension, heart failure, low ejection fraction, and in-hospital complications were more in (STSEACS) than (NSTSEACS), while (NSTEACS) patients received less Thrombolysis and Percutaneous coronary angioplasty P-value < 0.05.Conclusions: Acute coronary syndrome patients were younger and had more complications than others in the West. ST-Segment Elevation Myocardial Infarction Patients are more likely to develop in-hospital complications and to receive reperfusion therapy. The limitation of the study is the lack of follow-up information after discharge.Keywords: Acute coronary syndrome, primary, hospital outcome

Interaction of CO molecules with (Cu , Ag and Au) deposited on regular and defective MgO and BaO(001) surfaces: Density functional calculations

The adsorption properties and characteristics of CO on Cu, Ag and Au atoms deposited on various sites of the alkaline earth oxide MgO and BaO. The three members of morphological irregularities, terrace, edge, and oxygen terminated corner of MgO and BaO (001) surface have been studied by means of density functional calculations and embedded cluster model. The examined clusters were embedded in the simulated Coulomb fields that closely approximate the Madelung fields of the host surfaces. The  adsorption  properties  of  CO  have  been  analyzed  with reference  to  the  nature  of  the  oxide  support,  pairwise  and  non-pairwise  ..........Please read the full paper

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Towards a better understanding of detection properties of different types of plastic scintillator crystals using physical detector and MCNPX code

The purpose of this comprehensive research is to observe the impact of scintillator crystal type on entire detection process. For this aim, MCNPX (version 2.6.0) is used for designing of a physical plastic scintillation detector available in our laboratory. The modelled detector structure is validated using previous studies in the literature. Next, different types of plastic scintillation crystals were assessed in the same geometry. Several fundamental detector properties are determined for six different plastic scintillation crystals. Additionally, the deposited energy quantities were computed using the MCNPX code. Although six scintillation crystals have comparable compositions, the findings clearly indicate that the crystal composed of PVT 80% + PPO 20% has superior counting and detecting characteristics when compared to the other crystals investigated. Moreover, it is observed that the highest deposited energy amount, which is a result of the highest collision number in the crystal volume, corresponds to a PVT 80% + PPO 20% crystal. Despite the fact that plastic detector crystals have similar chemical structures, this study found that performing advanced Monte Carlo simulations on the detection discrepancies within the structures can aid in the development of the most effective spectroscopy procedures by ensuring maximum efficiency prior to and during use
