Early m.crorecanalization of vas deferens following biodegradable graft im.lantation in bilaterally vasectom.zed rats

We evaluated a biodegradable graft for reconstruction of rat vasa deferentia with long obstructed or m.ssing segm.nts. A total of 47 Sprague-Dawley rats underwent bilateral vasectom. and were divided into groups according to length of the vas deferens affected （0.5, 1, 1.5 cm.. After 8 weeks, poly-（D,L-lactide）（PDLA） grafts were used to reconnect the vas deferens, Grafts and adjoining vasa deferentia were excised 8 and 12 weeks later and evaluated m.croscopically. At 8 weeks, m.croscopic changes included a robust inflam.atory response around the grafts. All grafts were still intact but in the early stages of degradation. No m.crotubules, indicative of vas deferens recanalization, were identified. One specim.n showed evidence of healing and neovascularization at the interface zone between the vas deferens and the graft. At 12 weeks, grafts were further degraded but still present. m.croscopic evaluation showed decreased inflam.ation. Seven specim.ns showed neovascularization at the interface zone; two of these showed distinct epithelialized vas deferens m.crocanals at the graft edges. One specim.n showed a m.crocanal spanning the entire 0.5-cm.graft. A tim. period of 8 weeks is not am.le enough for vas deferens regeneration in the setting of a biodegradable PDLA graft; however, early evidence of re-growth was seen at 12 weeks. A longer healing tim. should perm.t further biodegradation of the graft, as well as re-growth and possible eventual reconnection of the vas deferens, allowing passage of sperm. These findings suggest a potential role for biodegradable grafts in the reconstruction ofvas deferens with long obstructed segm.nts.

HACEK organism. represent a rare but im.ortant group of causative pathogens in endocarditis. These bacteria have historically been associated with culture-negative endocarditis;however, m.dern laboratory techniques have m.de this less com.on. In this case, we present a 74-year-old m.n who presented with acute onset altered m.ntation, fever, and sepsis. He was ultim.tely found to have Haem.philus influenzae m.ningitis, cerebral em.yem., aortic valve endocarditis, psoas m.ositis, and L2 - L3 diskitis with osteom.elitis. Although HACEK organism. are com.only found in the oropharynx and upper respiratory tract in hum.ns, our patient did not report recent preceding dental or ENT procedures. H. influenzae is responsible for approxim.tely 0.16% of all cases of bacterial endocarditis, representing a very lim.ted subset. Although generally considered low virulent pathogens, this case dem.nstrates the unusual extent of infection from.a HACEK organism. H. influenzae, causing aortic valve endocarditis as well as atypical non-cardiac sequelae, including acute m.ningitis.

3-Dim.nsional Kinem.tic Com.arison of Arm.m.vem.nts between an Individual with NGLY1 Deficiency and a Neurotypical Individual

Phatak Bernhard Suter Departm.nt of Health and Hum.n Perform.nce University of Houston Houston TX USA Center for Neurom.tor and Biom.chanics Research University of Houston Houston TX USA Center for Neuro Engineering and Cognitive Science University of Houston Houston TX USA Departm.nt of Com.uter Science and Engineering Texas A&M University College Station TX USA Blue Bird Circle Rett Center Texas Children&#8217s Hospital Houston TX USA Baylor College of m.dicine Houston TX USA

NGLY1 Deficiency is an ultra-rare autosom.l recessively inherited disorder. Characteristic sym.tom. include am.ng others, developm.ntal delays, m.vem.nt disorders, liver function abnorm.lities, seizures, and problem. with tear form.tion. m.vem.nts are hyperkinetic and m.y include dysm.tric, choreo-athetoid, m.oclonic and dystonic m.vem.nt elem.nts. To date, there have been no quantitative reports describing arm.m.vem.nts of individuals with NGLY1 Deficiency. This report provides quantitative inform.tion about a series of arm.m.vem.nts perform.d by an individual with NGLY1 Deficiency and an aged-m.tched neurotypical participant. Three categories of arm.m.vem.nts were tested: 1) open ended reaches without specific end point targets;2) goal-directed reaches that included grasping an object;3) picking up sm.ll objects from.a table placed in front of the participants. Arm.m.vem.nt kinem.tics were obtained with a cam.ra-based m.tion analysis system.and “initiation” and “m.intenance” phases were identified for each m.vem.nt. The com.ination of the two phases was labeled as a “com.lete” m.vem.nt. Three-dim.nsional analysis techniques were used to quantify the m.vem.nts and included hand trajectory pathlength, joint m.tion area, as well as hand trajectory and joint jerk cost. These techniques were required to fully characterize the m.vem.nts because the NGLY1 individual was unable to perform.m.vem.nts only in the prim.ry plane of progression instead producing m.tion across all three planes of m.vem.nt. The individual with NGLY1 Deficiency was unable to pick up objects from.a table or effectively com.lete m.vem.nts requiring crossing the m.dline. The successfully com.leted m.vem.nts were analyzed using the above techniques and the results of the two participants were com.ared statistically. Alm.st all com.arisons revealed significant differences between the two participants, with a notable exception of the 3D initiation area as a percentage of the com.lete m.vem.nt. The stati
