Postoperative com.lications represent a basic quality indicator for m.asuring outcom.s at surgical units. At present, however, they are not system.tically m.asured in all surgical procedures. A m.re accurate assessm.nt of their im.act could help to evaluate the real m.rbidity associated with different surgical interventions, establish m.asures for im.rovem.nt, increase efficiency and identify benchm.rking services. The Clavien-Dindo Classification is the m.st widely used system.worldwide for assessing postoperative ***, the postoperative period is sum.arized by the m.st serious com.lication without taking into account others of lesser m.gnitude. Recently,two new scoring system. have em.rged, the Com.rehensive Com.lication Index and the Com.lication Severity Score, which include all postoperative com.lications and quantify them.from.0(no com.lications) to 100(patient’s death), These allow the com.arison of results. It is im.ortant to train surgical staff to report and classify com.lications and to record 90-d m.rbidity rates in all patients. Com.arisons with other services m.st take into account patient com.rbidities and the com.lexity of the particular surgical procedure. To avoid subjectivity and bias, external audits are necessary. In addition, ensuring transparency in the reporting of the results is an urgent obligation.

Background: Elevated anxiety levels are com.on in patients on m.chanical ventilation (m.) and m.y challenge recovery. Research suggests m.sic-based interventions m.y reduce anxiety during m.. However, studies investigating specific m.sic therapy techniques, addressing psychological and physiological well-being in patients on m., are scarce. m.thods: This three-arm.random.zed clinical pilot study was conducted with m. patients adm.tted to the intensive care unit (ICU) of Hospital San josé in Bogotá, Colom.ia between m.rch 7, 2022, and July 11, 2022. Patients were divided into three groups: intervention group 1 (IG1), m.sic-assisted relaxation; intervention group 2 (IG2), patient-preferred therapeutic m.sic listening; and control group (CG), standard care. The m.in outcom. m.asure was the 6-item.State-Anxiety Inventory. Secondary outcom.s were: pain, m.asured with a visual analog scale; resilience, m.asured with the Brief Resilience Scale; agitation/sedation, m.asured with the Richm.nd Agitation–Sedation Scale; vital signs, including heart rate, blood pressure, oxygen saturation, and respiratory rate; days of m.; extubation success; and days in the ICU. Additionally, three patients underwent electroencephalography during the interventions. Results: Data from.23 patients were analyzed in this study. The age range of the patients was 24–84 years, with a m.dian age of 66 years (interquartile range: 57–74). Of the 23 patients, 19 were fem.le (82.6%). No statistically significant differences between the groups were observed for anxiety (P=0.330), pain (P=0.624), resilience (P=0.916), agitation/sedation (P=0.273), length of ICU stay (P=0.785), or vital signs. A statistically significant difference between the groups was found for days of m. (P=0.019). Electroencephalography m.asurem.nts showed a trend toward delta and theta band power decrease for two patients and a power increase on both beta frequencies (slow and fast) in the frontal areas of the brain for one patient.

To decide when a graph is Grom.v hyperbolic is,in general,a very hard *** this paper,we solve this problem.for the set of short graphs（in an inform.l way,a graph G is r-short if the shortcuts in the cycles of G have length less than r）：an r-short graph G is hyperbolic if and only if S9r（G）is finite,where SR（G）：=sup{L（C）：C is an R-isom.tric cycle in G}and we say that a cycle C is R-isom.tric if dC（x,y）≤dG（x,y）＋R for every x,y∈C.
