Aim: Perinatal stroke is one of the main causes of hemiplegia and seizure disorder. This study aimed to analyse the clinical characteristics and outcomes of perinatal stroke in a cohort of Australian children for its early detection.

Methods: A population-based prospective longitudinal study on perinatal stroke up to 2 years of age, was conducted from 2017 to 2019.

Article Synopsis
  • - The study aimed to determine the birth prevalence of perinatal stroke in term infants and identify associated risk factors, despite some factors being present in healthy infants, which complicates risk assessment.
  • - Researchers analyzed perinatal stroke data from 2017 to 2019, finding a prevalence of 9.6 per 100,000 live births, with most cases (87%) showing multiple risk factors like cesarean section and low Apgar scores.
  • - The study concluded that while certain risk factors are statistically significant, they do not fully explain the causes of perinatal stroke, indicating a need for further validation through case-control studies.

Aim: The aetiology of perinatal stroke is poorly understood. This study aimed to prospectively confirm the risk factors and identify any previously unknown variables.

Methods: A prospective case-control study was conducted in Australia.

The prevalence of Herpes simplex virus 2 (HSV2) is increasing at an alarming rate in the world. Most of the HSV2 cases are not diagnosed properly, although a range of molecular and serological diagnoses exist. Herein, we have reported a very rapid detection method specific for HSV2 using real-time PCR.

Objectives: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) is currently a significant public health concern and causing a pandemic in the world. Despite immense attention to the coronavirus disease 2019 (COVID-19), very little attention has been given to the kinetics of disease progression in infected patients. Therefore, in this study, we present a 14-day clinical observation of hospital-admitted COVID-19 patients.

Context: Placental pathology may be an important missing link in the causal pathway of perinatal stroke. The study aim was to systematically review the literature regarding the role of the placenta in perinatal stroke. MEDLINE, Embase, Scopus, and Web of Science electronic databases were searched from 2000 to 2019.

More than 50% of infants with cerebral palsy (CP) are born at or near term, with the vast majority having pre- or perinatally acquired CP. While some have a clinical history predictive of CP, such as neonatal encephalopathy or neonatal stroke, others have no readily identifiable risk factors. Paediatricians are often required to discriminate generalised motor delay from a variety of other diagnoses, including CP.

With the aim of assessing the antigenic characteristics of a circulating pool of fowlpox virus (FPV) that exists in the backyard poultry system in India, one of the field isolates generated was characterized by in vitro immunologic techniques. FPV was isolated from clinically positive fowlpox cases (n  =  10) from the Jhargram (West Midnapur district) and Kakdwip (South 24 Pargana district) areas of West Bengal State, India. Initially, FPV-specific PCR was performed for confirmation of the samples.

This study investigates, for the first time, the NOx, N2O, SO3, and Hg emissions from combustion of a Victorian brown coal in a 10 kWth fluidized bed unit under oxy-fuel combustion conditions. Compared to air combustion, lower NOx emissions and higher N2O formation were observed in the oxy-fuel atmosphere. These NOx reduction and N2O formations were further enhanced with steam in the combustion environment.
