It consists of a retrospective study with twenty-two individuals diagnosed with DRC: fourteen HD and eight CAPD, followed up in the dialysis center of Antonio Pedro University Hospital (HUAP) of Fluminense Federal University (UFF), between 2015 and 2017. Fifteen healthy control (HC) subjects were included, without diagnosed CKD. Patients with HIV positive, hepatitis A, B, and C, pregnant, cancer, smokers, alcoholics and those exposed to X-rays in the last 3 months, were excluded. objectives: As oxidative stress and endothelial dysfunction may be linked to the higher prevalence of CVD in CKD patients, we measured the activities of the antioxidants enzymes: SoD and GPx and total No levels in the plasma and serum of end-stage CKD patients undergoing dialysis therapy, comparing with the HC group. Methods: Quantification of No levels was performed by fluorometric kit, while activities of SoD and GPx were determined using kinetic methods. Results: We found higher plasma SoD activity in HD (8.58 U/ml) and CAPD (10.14 U/ml), compared to C (3.73 U/ml) group, while GPx activity was decreased in HD (115.38 nmol/h/ml) and CAPD (122.76 nmol/h/ml) groups compared to HC group (275.83 nmol/h/ml). Total serum No concentration was decreased in HD (14.09 pmol/μl) and CAPD (10.26 pmol/μl), compared to non-CKD patients (49.65 pmol/μl). Conclusion: Decreased total serum No and GPx activities may lead to endothelial dysfunction and consequently a higher prevalence of CVD in CKD patients.

目的研究医源性早发性卵巢功能不全(premature ovarian insufficiency,PoI)性激素水平的变化及对糖代谢的影响。方法募集2022年1月到2024年4月就诊于首都医科大学附属北京妇产医院内分泌科的20~40岁的60例因造血干细胞移植(hematopoietic stem cell transplantation,HSCT)导致的医源性PoI患者和60例特发性PoI患者,一般资料包括身高、体质量、年龄,并计算体质量指数(body mass index,BMI),实验检测指标包括卵泡刺激素(follicle stimulating hormone,FSH)、黄体生成素(luteinizing hormone,LH)、雌二醇(estradiol,e 2)、皮质醇(cortisol,F)、总睾酮(total testosterone,TT)、游离睾酮(free testosterone,FT)、空腹血糖(fasting plasma glucose,FPG)及空腹胰岛素(fasting insulin,FINS)。结果医源性PoI患者体质量、BMI、e 2、TT、FT低于特发性PoI患者,差异有统计学意义(P均oI患者的FSH、LH、FINS、FPG高于特发性PoI患者,差异有统计学意义(P均oI患者与特发性PoI患者的年龄、身高和皮质醇相比,差异无统计学意义(P均>0.05)。医源性PoI患者高胰岛素血症的比例明显高于特发性PoI患者(P=0.025)。结论医源性PoI患者性激素水平的降低和糖代谢异常均比特发性PoI患者更加严重,可能原因是疾病治疗对卵巢功能的损伤更大。但医源性PoI是可以预防的。卵巢组织冻存(ovarian tissue cryopreservation,oTC)可以同时保护生育力和卵巢内分泌功能,使医源性PoI的防治从不可能变为可能,因此在接受放射治疗和化学药物治疗之前进行oTC十分有必要。

Background: Prostate cancer ranks as the second most prevalent malignancy in men, with treatment strategies ranging from observation to various interventions. Radical prostatectomy is a common approach, aiming for a cure, and the technique for vesico-urethral anastomosis varies, employing separate or continuous stitches. However, a consensus on the optimal technique is lacking. This study aims to compare vesico-urethral anastomosis techniques (separate vs. continuous stitches) in laparotomy-based radical prostatectomies, evaluating peri and postoperative outcomes. Materials and Method: A retrospective analysis of 140 patients’ medical records yielded 86 eligible cases, divided into two groups based on anastomosis technique. Both groups underwent surgery at the same urology center between 2016 and 2019, with a follow-up period exceeding 12 months. Pre-operative characteristics were statistically similar between groups. Results: Perioperative complication rates did not significantly differ between the two techniques (p > 0.99). However, the continuous stitch group experienced a 20-minute longer procedure time (p 0.05), patients with continuous stitches had 2.5 times higher diaper usage at twelve months (p Conclusion: This research suggests that vesico-urethral anastomosis with separate stitches yields superior results in laparotomy-based radical prostatectomies compared to continuous stitches, demonstrating benefits in surgical time, hospital stay, sentinel drain duration, stenosis rates, and long-term urinary incontinence outcomes.

The broke of a tailings dam from Vale S.A. destroyed a gigantic area killing 270 persons in Brumadinho/Brazil. organizing activities after a mass disaster is a complex process that requires the involvement of many people and resources in the laboratory. To DNA identification of the victims, a daunting work had to be made by DNA laboratory staff in a collaborative effort with many partners. efforts to implement good practice guidelines in Disaster Victim Identification (DVI) have revealed several important aspects that need to change in the forensic DNA laboratory. This article highlights the challenges of implementing DVI best practice guidelines in resource-poor settings, but with professionals from different sectors engaged in the same goal of briefly identifying victims and helping families and society.

家禽红螨(鸡皮刺螨)严重威胁世界各地的家禽生产和母鸡健康。鸡皮刺螨不但逐渐被认为是疫病重要的载体,而且有越来越多的报告显示其还可攻击包括人类在内的其他宿主,可见这种害虫对经济的影响变得越来越严重。随着世界各地的家禽生产逐渐脱离传统的笼养方式,鸡皮刺螨在禽群中的影响将变得更加普遍,防控将变得更加困难。尽管已有耐药性和治疗失败的报告,但鸡皮刺螨的防治仍以合成杀螨剂为主。目前在鸡皮刺螨及螨虫管理的专项研究报告中已经提出一些替代防治措施。尽管许多替代防治措施仍处于商业化前期阶段,但仍有部分措施已经逐渐进入市场。本综述汇集了日益扩充的鸡皮刺螨的研究,并评估了其当前和未来可供选择的防控措施。得出的结论是,鸡皮刺螨防治的重大进展最有可能来自综合防控的措施,将最新的研究融入到现有的和新型的防治策略中,这种融合将改进的监测和建模相结合,更好地为治疗和干预该病提供信息支持。
