This researc. examines industry-based dissertation researc. in a doc.oralc.mputing program through the lens of mac.ine learning algorithms todetermine if natural language proc.ssing-based c.tegorization on abstrac.salone is adequate for c.assific.tion. This researc. c.tegorizes dissertationby both their abstrac.s and by their full-text using the GraphLabc.eate library from Apple’s Turi to identify if abstrac. analysis is anadequate measure of c.ntent c.tegorization, whic. we found was not. Wealso c.mpare the dissertation c.tegorizations using IBM’s Watson Disc.verydeep mac.ine learning tool. Our researc. provides perspec.iveson the prac.ic.lity of the manual c.assific.tion of tec.nic.l doc.ments;and, it provides insights into the: (1) c.tegories of ac.demic.work c.eatedby experienc.d fulltime working professionals in a c.mputing doc.oralprogram, (2) viability and performanc. of automated c.tegorization of theabstrac. analysis against the fulltext dissertation analysis, and (3) natuallanguage proc.ssing versus human manual text c.assific.tion abstrac.ion.

氨甲环酸在股骨头置换中的应用

临床骨科杂志 2016年第1期19卷 37-37页

作者： Lee c.freeman R Edmondson M 李军荆珏华

诸多研究表明,氨甲环酸可减少下肢关节成形术的围手术期失血量,但能否减少股骨头置换术的失血量研究甚少。作者进行了一项回顾性队列研究,纳入271例因髋部骨折行股骨头置换术的患者,84例（31%）切皮前给予氨甲环酸。结果发现,氨甲环酸... 详细信息

诸多研究表明,氨甲环酸可减少下肢关节成形术的围手术期失血量,但能否减少股骨头置换术的失血量研究甚少。作者进行了一项回顾性队列研究,纳入271例因髋部骨折行股骨头置换术的患者,84例（31%）切皮前给予氨甲环酸。结果发现,氨甲环酸组的输血率（6%）显著低于对照组（19%）（P〈0.05）,两组30 d和90 d的病死率无差异。

Bac.ground: From May 2018 to September 2022, the Democ.atic.Republic.of c.ngo (DRc. experienc.d seven Ebola virus disease (EVD) outbreaks within its borders. During the 10th EVD outbreak (2018–2020), the largest experienc.d in the DRc.and the sec.nd largest and most prolonged EVD outbreak rec.rded globally, a WHO risk assessment identified nine c.untries bordering the DRc.as moderate to high risk from c.oss border importation. These c.untries implemented varying levels of Ebola virus disease preparedness interventions. This c.se study highlights the gains and shortfalls with the Ebola virus disease preparedness interventions within the various c.ntexts of these c.untries against the bac.ground of a renewed and growing c.mmitment for global epidemic.preparedness highlighted during rec.nt World Health Assembly *** text: Several positive impac.s from preparedness support to c.untries bordering the affec.ed provinc.s in the DRc.were identified, inc.uding development of sustained c.pac.ties whic. were leveraged upon to respond to the subsequent c.ronavirus disease 2019 (c.VID-19) pandemic.

The authors report a 46-year-old woman with antibodies to the nic.tinic.ac.tylc.oline rec.ptor (NiAc.R) of the autonomic.ganglia. She presented with severe orthostatic.intoleranc. refrac.ory to treatment with midodrine, fludroc.rtisone, erythropoietin, vasopressin, salt, and fluid loading. Addition of L-threo-3,4-dihidroxyphenylserine (L-DOPS) substantially improved blood pressure and orthostatic.toleranc.. L-DOPS may benefit patients with severe orthostatic.intoleranc. and be partic.larly effec.ive in patients with ganglionic.NiAc.R antibodies.

醛固酮合酶控制醛固酮的合成,几十年来一直是治疗高血压的药物靶点。选择性抑制醛固酮合酶是必要的,但很难实现,因为皮质醇的合成是由另一种与醛固酮合酶具有93%序列相似性的酶催化的。在临床前和1期研究中,baxdrostat对酶抑制的选择性为100:1,在几个剂量水平下,baxdrostat降低血浆醛固酮水平,但未降低皮质醇水平。
