Abstract

Improving caregivers' recognition of childhood malaria and pneumonia is crucial to early treatment and improving outcomes. The objective of this study was to assess the accuracy and reliability of caregivers' recognition of malaria and pneumonia (lay diagnosis) as compared to the revised IMCI guidelines. A cross-sectional study design was used to recruit 903 children aged 2-59 months who were assessed for malaria and pneumonia by health workers at five primary healthcare centres in Benin City, Nigeria. Accuracy of lay diagnosis as compared to the revised IMCI guidelines was assessed using sensitivity, specificity, positive and negative predictive values and area under the receiver operating characteristic curve (AUROC) values. The accuracy of caregivers' ability to recognise malaria (AUROC: 0.60; 95% CI: 0.57-0.64) and pneumonia (AUROC: 0.54; 95% CI: 0.50-0.58) was, respectively, moderate and poor as compared to the IMCI guidelines. Caregivers were better able to identify children without than those with malaria and pneumonia. Agreement between caregivers and the IMCI guidelines for malaria and pneumonia diagnosis was poor (k = 0.14, 95% CI: 0.09-0.19; P = 0.0001). Caregivers' ability to recognise these childhood diseases as co...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
