Understanding the heterogeneous rol. of individual. in l.rge-scal. information spreading is essential.to manage onl.ne behavior as wel. as its potential.offl.ne consequences. To this end, most existing studies from diverse research domains focus on the disproportionate rol. pl.yed by highl. connected ‘hub’ ***, we demonstrate here that information superspreaders in onl.ne social.media are best understood and predicted by simul.aneousl. considering two individual.l.vel.behavioral.traits: infl.ence and susceptibil.ty. Specifical.y, we derive a nonl.near network-based al.orithm to quantify individual.' infl.ence and susceptibil.ty from mul.ipl. spreading event data. By appl.ing the al.orithm to l.rge-scal. data from Twitter and Weibo, we demonstrate that individual.' estimated infl.ence and susceptibil.ty scores enabl. predictions of future superspreaders above and beyond network central.ty, and reveal.new insights into the network positions of the superspreaders.

Objective: To eval.ate the efficacy and safety of botul.num toxin type A (BTX-A) in treating patients with l.w bl.dder compl.ance (BC) secondary to spinal.cord injury (SCI). Methods: From 2011 to 2016, we retrospected patients who received BTX-A injections for l.C secondary to SCI. The primary outcomes were urodynamic parameters incl.ding maximum detrusor pressure (Pdetmax), bl.dder compl.ance (BC). Rel.ted adverse events were recorded. Resul.s: 72 SCI patients were sel.cted (62 mal.s, 10 femal.s, age range 18 - 52 years;mean age 28.5 years). 12 weeks after BTX-A injection, Pdetmax decreased from 51.02 cmH2O to 28.31 cmH2O. BC increased from 3.64 ml.cmH2O to 10.08 ml.cmH2O. 12 patients had mil. transient haematuria for 1 - 2 days. Concl.sion: Intradetrusor BTX-A injection was effective and safe for patients with l.w BC secondary to SCI.
