Long coronavirus disease (COVID) is a condition characterized by the emergence of new symptoms or the persistence of existing symptoms for at least two months, three months after the initial infection[1]. Although such a condition has initially been extensively studied, there are still many contra...
Studies on antibiotic duration for uncomplicated pneumonia in children suffer from major limitations, the most important of which is recruiting subjects unlikely to have bacterial pneumonia, thereby biasing results in favour of the null hypothesis. Therefore, substantial uncertainties remain over the optimal...
which is valid for both compressible and incompressible flows. Let’s now impose the incompressibility hypothesis. Incompressibility requires any fluid particle to have a constant density, which is mathematically expressed by the material derivative of the density: ...
However, this is a lower level study design in the hierarchy of evidence. The case series is nevertheless a useful hypothesis generator for future studies. These in turn can be tested with more robust study designs such as the randomized controlled trial. Because the case series remains the ...
Decreased exposure to bacteria in the early infancy period may shift the immune system to a predominantly Th2 state which is detected in atopic cases. Environmental exposure may lead to epigenetic changes which causes a shift of immune reactions against microorganisms. Summary The hygiene hypothesis ...

What is emerging market from a domestic perspective? What is the Bairoch hypothesis? What is an example of evidence for and against it? What is the importance of the invisible hand theory? What do the points along the frontier represent? What do you think is the most important goal of a ...
This study aimed to (1) describe psychometric properties of clinical outcome assessment for Rett syndrome and (2) identify what is needed to ensure that fit-for-purpose clinical outcome assessments are available for clinical trials. Methods Clinical outcome assessments for the top 10 priority domains...
This study has not classified the quality of the environment based on the Ministry of Environment and Forestry's categories, namely, the very good, good, quite good, poor, very poor and dangerous. For this reason, further research is needed using multiple discriminant analysis (MDA). Practical...
“immunogenicity of low molecular weight organic chemicals is dependent on modification of self-proteins,” evolved from Landsteiner and Jacob’s discovery of a correlation between the reactivity of dinitro-halogenated benzenes and their sensitization potential. The hypothesis rapidly evolved to encompass ...
