Refining the role of the chest radiograph in paediatric tuberculosis clinical care and research
… the absence of microbiological confirmation, and chest X-ray (CXR) is a critically important tool in diagnostic decision-making algorithms. In this PhD dissertation I evaluate how CXR, as a tool for both diagnosis and disease severity stratification, could be better used and its role refined, …

"A-OK": Chest Radiograph During Primary Survey Facilitates Faster, More Accurate Endotracheal Tube Position in Injured Children
… Support (ATLS) algorithm typically postpones radiographic confirmation of endotracheal tube (ETT) placement until the end of the secondary survey. Correct ETT depth is critical in pediatric trauma. We hypothesized that bedside confirmatory techniques are inaccurate and that early chest x-ray …

Effect of diabetes and HIV on radiographic manifestations of pulmonary tuberculosis
… on efficient diagnostic methods and tools. The chest radiograph remains a cornerstone in pulmonary tuberculosis diagnosis, especially in those where microbiological evidence of disease is lacking. A study was conducted to investigate the chest radiographic presentation of pulmonary tuberculosis …

Optimizing Tuberculosis Diagnosis in HIV-Infected Inpatients Meeting the Criteria of Seriously Ill in the WHO Algorithm
… days, unable to walk unaided, temperature >39oC, chest radiograph assessment, haemoglobin, and white cell count) was 0·811 (95%CI 0·802, 0·819). The classic tuberculosis symptoms (fever, night sweats, weight loss) added no discriminatory value in diagnosing tuberculosis. Xpert MTB/RIF assay …

Widened mediastinum on chest radiography as a prompt for further imaging in suspected blunt traumatic aortic injury: 3-year experience at a major trauma centre
… the presence of a widened mediastinum on a chest radiograph (CXR) as the commonest indication for chest computed tomography (CT) in cases of suspected blunt traumatic aortic injury (BTAI). Evaluating the practical implementation and accuracy of this tool could improve the degree of …

Imaging Based Models to Improve Lung Cancer Diagnosis
… to better detect and locate lung cancer from chest radiographs (x-rays) and computed tomography (CT) scans, as well as accurately estimate the risk of future lung cancer, all while factoring in the importance of model explainability in clinical settings. Recent advances in deep learning have …

Determinants of functional capacity and work ability post SARS-COV-2 infection in miners
… Scale (PCFS), Work Ability Index (WAI), chest radiograph and the Two-minute Walk Test (TMWT). Data analysis was done using STATA version 16 to generate univariate and multivariate quantile regression models. Results: The majority (74%) of the participants were males with a mean age of …

Improving the care of infants with bronchiolitis : Using knowledge translation to close the evidence-practice gap
… glucocorticoids, adrenaline or ordering chest radiographs. Despite evidence that these five therapies and management processes have no benefit, variation in clinical practice occurs with infants receiving non-evidence-based and potentially harmful care. The purpose of this implementation …

A study to evaluate immunodiagnostic tests for tuberculosis infection and determinants of TB infection in a population of health care workers in the Western Cape of South Africa
… including a TB symptom screen and underwent chest radiograph and rapid HIV test. Three tests for latent TB infection were administered: TST, QuantiFERON - TB Gold In - Tube (QFT - GIT) and a T - SPOT.TB test. All tests were repeated one year later. Results: The prevalence of TB infection at …

Multi-Level Learning Approaches for Medical Image Understanding and Computer-aided Detection and Diagnosis
… This approach is evaluated on a large-scale chest radiograph view identification task and a multi-class radiograph annotation task, demonstrating its improved performance in comparison with other state-of-the-art algorithms. It also achieves high accuracy and robustness against images with …

Survival of South-African HIV infected patients
… (PTB) in HIV infected patients presents with a radiographic spectrum reflecting the degree of HIV induced immune suppression. Chest radiographs and pre-treatment total lymphocyte counts provide prognostic information. Upper zone cavitatory infiltrates typical of reactivation PTB were associated …

Does helminth treatment reduce the risk of active tuberculosis in a cohort of children from high tuberculosis risk population who have been vaccinated with BCG at birth?
… physical examination, tuberculin skin test, chest radiograph, gastric washing and induced sputum for culture of tuberculosis and clinical examination. A diagnostic algorithm was developed by specialist physicians and biostatisticians to classify the children into one of five tuberculosis …

Assessment and optimisation of digital radiography systems for clinical use
… ultrasound. Initially the transition to general radiography was slow and fragmented but in the last 10-15 years in particular, huge investment by the manufacturers, greater and cheaper computing power, inexpensive digital storage and high bandwidth data transfer networks have lead to an enormous …

Relación entre los hallazgos radiográficos y la sintomatología respiratoria en trabajadores expuestos a polvo de carbón en minería de socavón en el departamento de Boyacá, Colombia 2015
Introducción: La inhalación de polvo de carbón favorece el desarrollo de neumoconiosis, causa daños irreversibles al pulmón que se identifican radiológicamente. Los síntomas son tardíos y la patología se puede desarrollar tras varios años de exposición. Objetivo: Caracterizar los hallazgos …
