COVID-19 has taken the world by storm in the ongoing pandemic. The virus responsible for COVID-19 disease is 'severe acute respiratory syndrome coronavirus-2' SARS-CoV-2, an enveloped RNA beta-coronavirus from the family Coronaviridae. There have been similar beta-coronavirus disease outbreaks previously: Severe acute respiratory syndrome (SARS - 2002) and Middle East respiratory syndrome (MERS - 2012) epidemics. SARS-CoV-2 origins have been traced to bat reservoirs. A virus with a high capacity for mutation, SARS-CoV-2 poses unique challenges both in the current form of disease control and management, while also leaving the door open for future novel diseases and pandemics. An understanding of the virion structure and genomic organisation will help us in understanding their origins and likely course of future evolution. Moreover, novel cost-effective methodologies for genetic surveillance may help in mitigating the emergence of these viral infections in future. In this manuscript, the authors have detailed the unique aspects of the SARS-CoV-2 virus genome and its clinical implications.

Background: Fluid management is a crucial critical care component, influencing outcomes such as organ function, renal integrity, and survival in critically ill patients. Recent evidence suggests that balanced crystalloids may offer advantages over isotonic saline, particularly in reducing the risk of acute kidney injury (AKI) and other complications. This study aimed to evaluate the impact of balanced crystalloids versus isotonic saline on clinical outcomes in the intensive care unit (ICU), focusing on AKI, renal replacement therapy (RRT), and mortality.

This study investigated the relationship between maternal serum amyloid A (SAA) levels, a biomarker of systemic inflammation, and specific neonatal outcomes in preterm birth (PTB). The study included 66 consecutive pregnant women hospitalized for spontaneous preterm delivery (ranging from 28 to 36 gestational weeks), at the Timisoara Municipal Hospital. The study measured mSAA levels to assess their potential as predictors of fetal outcomes (respiratory distress syndrome [RDS]), as well as their association with APGAR score, neonatal leukocyte count, and C-reactive protein (CRP) levels as indicators of neonatal status and response.

Background: Intrathecal (IT) chemotherapy is essential in treating hematological malignancies, but it can lead to ascending paraplegia, a condition that currently lacks clear management guidelines.

Methods: We conducted a systematic review, analyzing 1219 studies and 116 patients, adhering to PRISMA guidelines for individual patient data. The study, registered under PROSPERO (CRD42022362121), focused on the onset, diagnostic approaches, and therapeutic interventions associated with this complication, and management strategies to tackle the ascending paraplegia.

Unlabelled: A 16-year-old man presented to the Accident and Emergence services with a 10-day history of shortness of breath, sore throat, vomiting, diarrhoea, poor oral intake, chest pain, jaundice, diplopia and reduced urine output. He was initially treated for sepsis, however, subsequent imaging and blood cultures confirmed the diagnosis of Lemierre's syndrome (LS). LS, also known as necrobacillosis or post-pharyngitis anaerobic septicaemia is comprised of a triad of metastatic septic emboli secondary to pharyngitis, bacteraemia, and internal jugular vein thrombophlebitis.
