Improving performance of CNN to predict likelihood of COVID-19 using chest X-ray images with preprocessing algorithms [PDF]

open access: yesInternational Journal of Medical Informatics, 104284. 23 Sep. 2020, 2020
As the rapid spread of coronavirus disease (COVID-19) worldwide, chest X-ray radiography has also been used to detect COVID-19 infected pneumonia and assess its severity or monitor its prognosis in the hospitals due to its low cost, low radiation dose, and wide accessibility.

Pneumococcal carriage, serotype distribution and risk factors in children with community-acquired pneumonia, 5 years after introduction of the 10-valent pneumococcal conjugate vaccine in Ethiopia [PDF]

open access: yes, 2019
Background: There is a scarcity of data on pneumococcal serotypes carried by children in Ethiopia. We studied pneumococcal nasopharyngeal carriage rate, serotypes, and risk factors among children with community acquired pneumonia (CAP).

Doubly Robust Proximal Synthetic Controls [PDF]

open access: yesarXiv, 2022
To infer the treatment effect for a single treated unit using panel data, synthetic control methods construct a linear combination of control units' outcomes that mimics the treated unit's pre-treatment outcome trajectory. This linear combination is subsequently used to impute the counterfactual outcomes of the treated unit had it not been treated in ...

CXR-Net: An Encoder-Decoder-Encoder Multitask Deep Neural Network for Explainable and Accurate Diagnosis of COVID-19 pneumonia with Chest X-ray Images [PDF]

open access: yes, 2021
Accurate and rapid detection of COVID-19 pneumonia is crucial for optimal patient treatment. Chest X-Ray (CXR) is the first line imaging test for COVID-19 pneumonia diagnosis as it is fast, cheap and easily accessible. Inspired by the success of deep learning (DL) in computer vision, many DL-models have been proposed to detect COVID-19 pneumonia using ...

The Annexin A1/FPR2 pathway controls the inflammatory response and bacterial dissemination in experimental pneumococcal pneumonia

open access: yesThe FASEB Journal, 2019
Streptococcus pneumoniae is a major cause of community‐acquired pneumonia leading to high mortality rates. Inflammation triggered by pneumococcal infection is necessary for bacterial clearance but must be spatially and temporally regulated to prevent ...

Pneumococcal pneumonia and the risk of stroke: a population-based follow-up study. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: To investigate the risk of developing stroke in patients hospitalized following a diagnosis of pneumococcal pneumonia. METHODS: The study cohorts comprised of patients hospitalized with a principal diagnosis of pneumococcal pneumonia (n ...

Effectiveness of 13-Valent Pneumococcal Conjugate Vaccine Against Hospitalization for Community-Acquired Pneumonia in Older US Adults: A Test-Negative Design

open access: yesClinical Infectious Diseases, 2018
Our study demonstrated real-world, direct effectiveness of 13-valent pneumococcal conjugate vaccine against vaccine-type community-acquired pneumonia following introduction into a routine immunization program among adults aged ≥65 years, many of whom had

Monitoring the introduction of pneumococcal conjugate vaccines into West Africa: design and implementation of a population-based surveillance system. [PDF]

open access: yes, 2012
Routine use of pneumococcal conjugate vaccines (PCVs) in developing countries is expected to lead to a significant reduction in childhood deaths. However, PCVs have been associated with replacement disease with non-vaccine serotypes.

Impact of pneumococcal conjugate vaccines on hospitalizations for pneumonia in the United States

open access: yesExpert Review of Vaccines, 2019
Introduction: Pneumonia is one of the leading causes of morbidity and mortality among children and older adults. Pneumococcal conjugate vaccines (PCVs) were introduced into the US routine infant vaccination schedule leading to substantial reductions of ...
