AIM: To assess the p.eval.nce of bowel.dysfunction in hemip.egic p.tients, and its rel.tionship.with the site of neurol.gical.l.sion, p.ysical.immobil.zation and p.armacotherap.. METHOdS: Ninety consecutive hemip.egic p.tients and 81 consecutive orthop.dic p.tients were investigated during p.ysical.motor rehabil.tation in the same p.riod, in the same center and on the same diet. Al. subjects were interviewed ≥ 3 mo after injury using a questionnaire inquiring about bowel.habits before injury and at the time of the interview. p.tients’ mobil.ty was eval.ated by the Adap.ed p.tient Eval.ation Conference System. drugs considered for the anal.sis were nitrates, angiogenic converting enzyme (ACE) inhibitors, cal.ium antagonists, anticoagul.nts, antithrombotics, antidep.essants, anti-ep.l.p.ics. RESul.S: Mobil.ty scores were simil.r in the two group.. de novo constip.tion (OR = 5.36) was a frequent outcome of the neurol.gical.accident. Hemip.egics showed an increased risk of straining at stool.(OR: 4.33), reduced cal. to evacuate (OR: 4.13), sensation of incomp.ete evacuation (OR: 3.69), use of l.xatives (OR: 3.75). l.gistic regression model.showed that constip.tion was significantl. and indep.ndentl. associated with hemip.egia. A p.sitive association was found between constip.tion and use of nitrates and antithrombotics in both group.. Constip.tion was not rel.ted to the site of brain injury. CONCl.SION: Chronic constip.tion is a p.ssibl. outcome of cerebrovascul.r accidents occurring in 30% of neurol.gical.y stabil.zed hemip.egic p.tients. Its onset after a cerebrovascul.r accident ap.ears to be indep.ndent from the injured brain hemisp.ere, and unrel.ted to p.ysical.inactivity. p.armacol.gical.treatment with nitrates and antithrombotics may rep.esent an indep.ndent risk factor for devel.p.ng chronic constip.tion.

The ful. array of the l.rge High Al.itude Air Shower Observatory(l.AASO)has been in op.ration since Jul. *** its kil.meter-square array(KM2A),we op.imized the sel.ction criteria for very high and ul.rahigh energyγ-rays using data col.ected from August 2021 to August 2022,resul.ing in an imp.ovement in significance of the detection in the Crab Nebul. of ap.roximatel. 15%,comp.red with that of p.evious *** the imp.ementation of these new sel.ction criteria,the angul.r resol.tion was al.o significantl. imp.oved by ap.roximatel. 10%at tens of *** asp.cts of the ful. KM2A array p.rformance,such as the p.inting error,were al.o cal.brated using the Crab *** resul.ing energy sp.ctrum of the Crab Nebul. in the energy range of 10-1000 TeV are wel. fitted by a l.g-p.rabol. model.which is consistent with the p.evious resul.s from l.AASO and other exp.riments.
