Background and Objectives: The main benefits of laparoscopic surgery in comparison to open surgery involve the rapid discharge from recovery room, decreased postoperative hospital stays, reduced postoperative discomfort, easier getting back to work and faster return to ordinary daily life as well as cosmetic surgical wounds. The anesthesia type has an essential role in attenuation of the surgical stress and achievement of these advantages. We aimed to determine the outcome of giving general anesthesia in conjunction with thoracic epidural analgesia (TEA) compared to general anesthesia alone on stress response to surgery and anesthesia by investigating cytokine reaction (interleukin 6 and 8 levels), hemodynamic changes (BP, HR, RR, SPO2), and Visual Analogue Scale (VAS) scores postoperatively in patients subjected for laparoscopic cholecystectomy. Methods: This study included 40 patients aged 20 - 60 years old with American Society of Anesthesiologists physical status (ASA) I and II. They were planned for laparoscopic cholecystectomy at Aswan University Hospital from April 2017 to March 2018. They were randomly allocated into two groups. Group A (n. 20) received general anesthesia only and Group B (n. 20) received general anesthesia in conjunction with thoracic epidural analgesia using fentanyl and bupivacaine in the epidural catheter. Chi-square was applied to differentiate categorical variables, whereas comparison between continuous variables was done by using t-test. Two-tailed p ficant. Results: As regards IL-6 and IL-8 post-operative there is significant difference (p nd and 4th h

无线传感器网络中的节点由于自身能量的消耗,及外部因素影响会导致节点出现大规模的失效,从而把无线传感器网络分割成几个独立的不能相互通信的分区。为恢复网络,重建分区之间的通信链路,提出基于三角形斯坦纳树连通恢复算法。该算法首先利用传统算法实现分区连通,然后通过构建三角形斯坦纳树以减少部署的中继节点数量。与现有的一些算法相比,该方法形成的网络拓扑不仅减少了部署中继节点的数量,能够使分区重新连通,而且能够减少网络通信的能量消耗。实验结果表明,所提方法相对于传统算法在构建网络拓扑时更加有效。

Int.oduct.on: Sexualit. in t.e post.art.m period is a t.boo subject.t.at.raises many quest.ons, especially among women. t.e aim of t.is st.dy was t. evaluat. t.e influence of fact.rs such as mode of delivery, parit., t.pe of household and level of educat.on on t.e resumpt.on of sexualit., by comparing our result. wit. t.ose in t.e lit.rat.re. Met.ods: t.is is a prospect.ve descript.ve and analyt.cal st.dy, which t.ok place from 3 April t. 2 June 2023 in t.e mat.rnit. ward of t.e Ignace deen Nat.onal Hospit.l of t.e Universit. Hospit.l Cent.e of Conakry. t.e sample included married women who had given birt. once or several t.mes. Result.: Of 118 married women who had given birt. once or several t.mes and who were quest.oned about.t.eir sexualit. in t.e post.art.m period, 75.42% (89 cases) st.t.d t.at.t.ey had resumed sexual act.vit. in t.e post.art.m period. (t.e majorit. were aged 20 - 29 years (46.61%), pauci pares (51.69%), living in a monogamous household (88.14%), wit. secondary educat.on (44.92%) and self-employed (38.98%). More t.an half (58.47%) of t.ese women had a normal vaginal delivery wit. vulvo-perineal t.ar (5.80%), episiot.my (15.94%) and inst.ument.l ext.act.on (8.69%). t.e main reasons for resuming sexual act.vit. were t.e desire t. sat.sfy t.eir part.er (50.56%) and t. maint.in t.e harmony of t.e couple (29.21%). Resumpt.on of sexual act.vit. was more common in pat.ent. who had given birt. by caesarean sect.on (p = 0.007) and in pat.ent. wit. a higher level of educat.on (p = 0.03). However, it.was not.influenced by parit. or household t.pe. Conclusion: Sexualit. remains a t.boo subject. and it. resurgence in t.e post.art.m period is influenced by t.e mode of delivery and t.e level of educat.on and percept.on of women. Cert.in pract.ces and complicat.ons relat.d t. childbirt. can also influence t.e resumpt.on of sexualit. in t.e post.art.m period.
