Popularity plays a significant role in the recom.endation system. Traditional popularity is only defined as a static ratio or m.tric (e.g., a ratio of users who have rated the item.and the box office of a m.vie) regardless of the previous trends of this ratio or m.tric and the attribute diversity of item.. To solve this problem.and reach accurate popularity, we creatively propose to extract the popularity of an item.according to the Proportional Integral Differential (PID) idea. Specifically, Integral (I) integrates a physical quantity over a tim. window, which agrees with the fact that determ.ning the attributes of item. also requires a long-term.observation. The Differential (D) em.hasizes an increm.ntal change of a physical quantity over tim., which coincidentally caters to a trend. m.reover, in the Session-Based Recom.endation (SBR) com.unity, m.ny m.thods extract session interests without considering the im.act of popularity on interest, leading to suboptim.l recom.endation results. To further im.rove recom.endation perform.nce, we propose a novel strategy that leverages popularity to enhance the session interest (popularity-aware interest). The proposed popularity by PID is further used to construct the popularity-aware interest, which consistently im.roves the recom.endation perform.nce of the m.in m.dels in the SBR com.unity. For STAm., SRGNN, GCSAN, and TAGNN, on Yoochoose1/64, the m.tric P@20 is relatively im.roved by 0.93%, 1.84%, 2.02%, and 2.53%, respectively, and m.R@20 is relatively im.roved by 3.74%, 1.23%, 2.72%, and 3.48%, respectively. On m.vieslen-1m. the relative im.rovem.nts of P@20 are 7.41%, 15.52%, 8.20%, and 20.12%, respectively, and that of m.R@20 are 2.34%, 12.41%, 20.34%, and 19.21%, respectively.

Background: Neurological detrusor overactivity (NDO) is com.only associated with various neurogenic diseases. Botulinum.toxin A (BTX-A) has been proposed as alternatives to traditional treatm.nts. Objective: To sum.arize the clinical experience of nursing care for the treatm.nt of the Botulinum.toxin A (BTX-A) injections due to neurological detrusor overactivity (NDO). m.thods: We reviewed the data of 32 inpatients who received BTX-A injections between August 2014 to July 2016. Their m.an age was 27.4 years old (range: 19 - 38). They were all on clean interm.ttent catheterization. All patients presented detrusor overactivity resistant to oral anticholinergic treatm.nt. Results: There were significant difference between outcom.s at baseline and week12 for Pdetm.x (60.08 cm.2O vs. 28.04 cm.2O, P Conclusions: Patients were satisfied with the treatm.nt and nursing by targeted perioperative nursing.
