Reducing inappropriate antibiotics prescribing: The role of online commentary on physical examination findings [PDF]

, 2010
Objective: This study investigates the relationship of ‘online commentary’(contemporaneous physician comments about physical examination [PE] findings) with (i) parent questioning of the treatment recommendation and (ii) inappropriate antibiotic ...

Ex-nihilo II: Examination Syllabi and the Sequencing of Cosmology Education [PDF]

Phys.Educ. 38 (2003) 243, 2003
Cosmology education has become an integral part of modern physics courses. Directed by National Curricula, major UK examination boards have developed syllabi that contain explicit statements about the model of the Big Bang and the strong observational evidence that supports it. This work examines the similarities and differences in these specifications,

Effect of different noise reduction techniques and template matching parameters on markerless tumor tracking using dual‐energy imaging

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose To evaluate the impact of various noise reduction algorithms and template matching parameters on the accuracy of markerless tumor tracking (MTT) using dual‐energy (DE) imaging. Methods A Varian TrueBeam linear accelerator was used to acquire a series of alternating 60 and 120 kVp images (over a 180° arc) using fast kV switching, on ...

Effects of BRCA1 and BRCA2 gene mutations on female fertility among Chinese women: A systematic review and meta-analysis [PDF]

BIO Web of Conferences, 2023
Purpose: It is still inconsistent whether the mutations of BRCAs could reduce the female fertility by increasing the prevalence of breast and ovarian cancer. So we focus on the effects of BRCAs mutations onthe female fertility among Chinese women in this

Physical Examination

, 2022
Older adults display heterogeneous changes in anatomy and physiology. These changes often lead to atypical presentation of diseases, loss of function, and increased risk of disability. Older adults are also most likely to have multiple comorbidities1; they often overestimate healthiness and underestimate severity of disease.

Atherogenic index of plasma is a novel and strong predictor associated with fatty liver: a cross-sectional study in the Chinese Han population

Lipids in Health and Disease, 2019
Background Atherogenic index of plasma (AIP) has been reported to be an important predictor for coronary artery disease and obesity. However, few studies has yet systematically evaluated the association between AIP and Fatty Liver (FL) and its advantage ...

Tadpole Method and Supersymmetric O(N) Sigma Model [PDF]

J.Phys.G22:1127-1136,1996, 1996
We examine the phase structures of the supersymmetric O(N) sigma model in two and three dimensions by using the tadpole method. Using this simple method, the calculation is largely simplified and the characteristics of this theory become clear. We also examine the problem of the fictitious negative energy state.

Accuracy of patient dose estimation in cone beam computed tomography in breast irradiation by size‐specific dose estimates with position correction

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract This study aims to investigate the effects of the position correction of size‐specific dose estimates (SSDE) on patient dose estimation in cone beam computed tomography (CBCT). The relationship between the phantom position and absorbed dose in the right breast was studied using optically stimulated luminescence dosimeters and a simulated human

Evaluation of patient doses for routine digital radiography procedures toward establishing an institutional diagnostic reference levels: A case study in Sri Lanka

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract The present study was conducted as part of a comprehensive work to establish National Diagnostic Reference Levels (NDRLs) in Sri Lanka for the first time. DRLs can be used as an effective optimization tool for identifying unusually high or low patient doses during X‐ray examinations.
