Division of Medical Virology, Department of Pathology, Faculty of Health Sciences, University of Cape Towngrid.7836.a, Cape Town, South Africa.

Bacterial vaginosis (BV) is a common polymicrobial vaginal disorder that is associated with sexually transmitted infections (STIs), including HIV. Several studies have utilized broad-range 16S rRNA gene PCR assays with sequence analysis to characterize cervicovaginal bacterial communities of women with healthy and diseased conditions. With the high burden of BV and STIs among African women, there is a need for targeted PCR assays that can rapidly determine the true epidemiological profile of key cervical microbes, including BV-associated bacteria, and a need to explore the utility of such assays for microbiological diagnosis of BV.

Detection of pathogens associated with early-onset neonatal sepsis in cord blood at birth using quantitative PCR.

Wellcome Open Res 2022 11;7. Epub 2022 May 11.

Clinical research, KEMRI-Wellcome Trust Research Programme, Kilifi, Kenya.

Early onset neonatal sepsis (EONS) typically begins prior to, during or soon after birth and may be rapidly fatal. There is paucity of data on the aetiology of EONS in sub-Saharan Africa due to limited diagnostic capacity in this region, despite the associated significant mortality and long-term neurological impairment. We compared pathogens detected in cord blood samples between neonates admitted to hospital with possible serious bacterial infection (pSBI) in the first 48 hours of life (cases) and neonates remaining well (controls).

Undifferentiated non-hepatic hyperammonemia in the ICU: Diagnosis and management.

J Crit Care 2022 08 18;70:154042. Epub 2022 Apr 18.

Department of Anesthesiology, University of Minnesota Medical School, Departments of Anesthesiology & Medicine, University of Wisconsin Hospitals and Clinics, Madison, WI, United States of America.

Hyperammonemia occurs frequently in the critically ill but is largely confined to patients with hepatic dysfunction or failure. Non-hepatic hyperammonemia (NHHA) is far less common but can be a harbinger of life-threatening diagnoses that warrant timely identification and, sometimes, empiric therapy to prevent seizures, status epilepticus, cerebral edema, coma and death; in children, permanent cognitive impairment can result. Subsets of patients are at particular risk for developing NHHA, including the organ transplant recipient. Read More
