Objectives: Group B streptococcus (GBS) infection is a serious disease that continues to cause high morbidity and mortality. It is one of the leading cause of sepsis; particularly meningitis, in infants and young children all around the world. In this study, we aim to identify the incidence of GBS sepsis in Omani infants less than 3 months of age who were born at Royal Hospital and who presented with clinical sepsis and positive culture. In addition, we aim to describe the clinical presentation and complications noted on admission and then on follow-up visit.
Methods: This is an observational retrospective chart review study. It included all Omani infants (0-3 months) who were diagnosed to have GBS sepsis/meningitis from 2006 to 2016 at the Royal Hospital, Muscat, Sultanate of Oman.
Results: There were 83,000 live births in the Royal Hospital over a period of 10 years. Thirty-eight babies had culture proven GBS infection, with an overall incidence rate of neonatal GBS of 0.46 per 1000 live births with 95% confidence intervals. There were no significant variations in the annual rates of infection during the study period, ranging from around 1-7 cases per year. Additional 5 cases of GBS sepsis presented to Royal Hospital are either through Emergency Department or as referrals from other hospitals, giving us a total of 43 cases of proven GBS infections. Out of the 43 cases, 8 were born prematurely (19%), either before (<34 weeks, n = 2) or during (34-36 weeks, n = 6). Term babies were 35 out of 43 with percentage of 81% of the total. Three died, resulting in a case mortality of 7.0%.
Conclusion: Our GBS incidence is comparable to that of screened population internationally. At the time being, with the best available results, maternal screening might not seem cost effective in our current settings. A cost effective study is required before implemented a national screening programme in the Country. However, this research will definitely help in the process of any future plans of implantation of new guidelines, as it can be used as leading point for future prospective studies.

Improved accuracy of delayed cerebral ischemia diagnosis with plasma nitric oxide synthase 3, nicotinamide adenine dinucleotide phosphate, and 8-iso-prostaglandin F2α.

Objective: The pathophysiology of delayed cerebral ischemia (DCI) is not fully elucidated. The lack of accurate diagnostic tools increases the probability of delayed diagnosis and timely treatment. The authors assessed the relationship of 8-iso-prostaglandin F2α (F2-IsoP) and oxidative stress biomarkers, nitric oxide synthase 3 (NOS3) and nicotinamide adenine dinucleotide phosphate (NADPH), with DCI after aneurysmal subarachnoid hemorrhage (aSAH).

Introduction: Given its proximity to the central nervous system, surgical site infections (SSIs) after craniotomy (SSI-CRAN) represent a serious adverse event. SSI-CRAN are associated with substantial patient morbidity and mortality. Despite the recognition of SSI in other surgical fields, there is a paucity of evidence in the neurosurgical literature devoted to skin closure, specifically in patients with brain tumors.

Background: Despite an epidemic of End-Stage Kidney Disease in the Australian Aboriginal and Torres Strait Islander population, disparities in access to kidney transplantation persist. The journey to successful kidney transplant is long, with an initial suitability assessment required before waitlist-specific activities begin. In an Aboriginal Community Controlled renal service, we aimed to: 1.

Background: Contrast-associated acute kidney injury (CA-AKI) is frequent in patients with chronic kidney disease who are submitted to cardiac endovascular procedures using iodinated contrast. In hemoadsorption, cartridges containing styrene-divinylbenzene sorbent resin are applied to remove substances from the blood through an extracorporeal circuit. Importantly, iodinated contrast is also removed via adsorption.

Data regarding Penicillin allergy labels (PALs) from India and Sri Lanka are sparse. Emerging data suggests that the proportion of patients declaring an unverified PAL in secondary care in India and Sri Lanka (1%-4%) is lesser than that reported in High Income Countries (15%-20%). However, even this relatively small percentage translates into a large absolute number, as this part of the world accounts for approximately 25% of the global population.
