Plant-Assisted Green Synthesis of MgO Nanoparticles as a Sustainable Material for Bone Regeneration: Spectroscopic Properties.

This work is devoted to magnesium oxide (MgO) nanoparticles (NPs) for their use as additives for bone implants. Extracts from four different widely used plants, including , , , and , were evaluated for their ability to facilitate the "green synthesis" of MgO nanoparticles. The thermal stability and decomposition behavior of the MgONPs were analyzed by thermogravimetric analysis (TGA).

Challenges in the diagnosis and management of atypical fungal keratitis during the COVID-19 pandemic: a case series.

Fungal keratitis is a time-sensitive ocular infection that often requires a high index of suspicion followed by intensive medical/surgical interventions to achieve a successful clinical outcome. COVID-19 pandemic-related restrictions, necessitated the modification of conventional protocols and guidelines associated with the treatment of keratomycosis. We report four cases of atypical fungal keratitis with poorly differentiated clinical characteristics.

Validation of Cardiac Surgery Score (CASUS) in Postoperative Cardiac Patients.

. Cardiac Surgery Score (CASUS) was introduced in 2005 as the first postoperative scoring system specific for patients who had cardiac surgery. Prior to this, European System for Cardiac Operative Risk Evaluation (EuroSCORE) has been used preoperatively, while Intensive Care National Audit and Research Centre Score (ICNARC) and Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, which are widely used in general intensive care unit population, have been used to score cardiac patients postoperatively.

Giant right coronary artery aneurysm presenting as an STEMI.

Giant coronary artery aneurysms are an infrequent finding. They are typically discovered incidentally, rarely presenting with any symptoms. We present the case of a 72-year-old gentleman who presented with an ST elevated myocardial infarction.

Prediction of Postoperative Outcomes and Long-Term Survival in Cardiac Surgical Patients Using the Intensive Care National Audit & Research Centre Score.

Objectives: Scoring systems used in cardiac surgery, such as the European System for Cardiac Operative Risk Evaluation and the Society of Thoracic Surgeons scoring systems, do not adjust for events that take place intraoperatively. The authors hypothesized that intensive care unit scoring systems such as the Intensive Care National Audit & Research Centre (ICNARC) could predict accurately not only in-hospital mortality, but also other significant complications, as well as long-term survival after cardiac surgery.

Design: Prospective cohort study using perioperative data from the ICNARC Audit and Dendrite database.

Mini-extracorporeal circulation technology, conventional bypass and prime displacement in isolated coronary and aortic valve surgery: a propensity-matched in-hospital and survival analysis.

Objectives: Conventional cardiopulmonary bypass is the most commonly used means of artificial circulation in cardiac surgery. However, it suffers from the effects of haemodilution and activation of inflammatory/coagulation cascades. Prime displacement (PD) can offset haemodilution and mini-extracorporeal technology (MIECT) can offset both.

Invasive pneumococcal disease in children aged younger than 5 years in India: a surveillance study.

Background: Invasive pneumococcal disease continues to be a major cause of morbidity and mortality among children younger than 5 years of age in India. We aimed to provide nationally representative data for the pattern of disease due to Streptococcus pneumoniae, trends in the serotype of invasive pneumococci, and invasive pneumococci antimicrobial resistance patterns, in India.

Methods: In this prospective hospital-based and retrospective laboratory-based surveillance study, we prospectively enrolled children aged younger than 5 years with suspected or proven invasive pneumococcal disease from 18 hospitals or institutional centres and retrospectively included laboratory-confirmed pneumococcal isolates from ten sentinel laboratories, together representing 11 states in India.

Long-term prognosis and a prediction model for acute bowel ischaemia following cardiac surgery.

Objectives: Bowel ischaemia following cardiac surgery is associated with a high postoperative mortality. No scoring system exists as yet to predict this complication following surgery. In addition, the long-term survival is not known.

Remote ischemic preconditioning does not affect the incidence of acute kidney injury after elective abdominal aortic aneurysm repair.

Objective: Open abdominal aortic aneurysm (AAA) repair is associated with a high risk of renal injury with few known strategies demonstrating a reduction in this risk. Remote ischemic preconditioning (RIPC) has been identified as having the potential to minimize organ injury following major vascular surgery. This trial investigated the potential for RIPC to attenuate renal and myocardial injury in patients undergoing elective open AAA repair.

Complex aortic surgery in a regional center in the United Kingdom. Should the United Kingdom now adopt a United States-style supercenter model?

Background: The United States has established aortic supercenters, which have demonstrated clear improvements in the short-term and long-term outcomes after surgery on the thoracic aorta. This model of care does not exist in the United Kingdom. We have looked at our recent experience of emergency and elective thoracic aortic surgery and describe and compare our operative outcomes and 10-year survival with other regional centers and supercenters worldwide.
