Cerebral infarcts, edema, hypoperfusion, and vasospasm in preeclampsia and eclampsia.

Background: Eclampsia is a serious pregnancy complication and is associated with cerebral edema and infarctions. However, the underlying pathophysiology of eclampsia remains poorly explored.

Objective: This study aimed to assess the pathophysiology of eclampsia using specialized magnetic resonance imaging to measure diffusion, perfusion, and vasospasm.

Computed tomography chest findings in post-acute COVID-19 lung disease at a South African regional hospital - a descriptive study.

Introduction: whilst many studies have focused on acute and chronic complications of COVID-19, few studies have been performed on the immediate post-acute COVID-19 phase complications. The objective of the study was to describe computed tomography (CT) imaging findings in patients from a South African (SA) cohort during the post-acute COVID-19 phase. To describe the findings using existing CT description systems and, if present, pulmonary imaging findings unique to our cohort.

Understanding the biology, morbidity and social contexts of adolescent tuberculosis: a prospective observational cohort study protocol (Teen TB).

Introduction: A considerable burden of the tuberculosis (TB) epidemic is found in adolescents. The reasons for increased susceptibility to TB infection and higher incidence of TB disease in adolescence, compared with the 5-10 years old age group, are incompletely understood. Despite the pressing clinical and public health need to better understand and address adolescent TB, research in this field remains limited.

Biomarkers to predict FDG PET/CT activity after the standard duration of treatment for spinal tuberculosis: An exploratory study.

Objectives: 18F-Fluorodeoxyglucose (FDG) Positron Emission Tomography- Computed Tomography (PET/CT) scans can be used to assess healing following treatment for spinal tuberculosis (TB) but have limited accessibility and high cost. This study investigated the association between immune biomarkers and FDG-PET/CT activity after ≥9 months of treatment for spinal TB.

Methods: Patients who had completed ≥9 months of treatment for spinal TB were recruited from a major hospital in the Western Cape, South Africa.

Relative Sparing of the Left Upper Zone on Chest Radiography in Severe COVID-19 Pneumonia.

The radiological findings of COVID-19 are well-described, including its evolution. In an earlier report of admission chest radiographs of patients with COVID-19, we anecdotally noted relative sparing of the left upper zone (LUZ). We subsequently aimed to describe the main chest radiograph findings in another cohort, focusing on zonal predominance.
