Introduction: The acromioclavicular joint is a superficial diarthrodial joint that surrounds the medial articular facet of the acromion and the distal portion of the clavicle. Due to its anatomy and biomechanics, it is highly susceptible to trauma and in young men who play contact sports, acromioclavicular dislocation is common. This article aimed to systematically review the literature and compare the surgical techniques used in the treatment of acromioclavicular dislocation in patients who practice sports. Methods: This systematic review was conducted according to the International Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines. Eligible studies for this systematic review included articles in English or Spanish published between 2013 and 2023, which mention the occurrence of acromioclavicular dislocation during sports practices. Additionally, only studies that addressed the surgical treatment of acromion-clavicular dislocation and contained original data on the topic were included. Results: We found 144 eligible studies after searching the LILACS and PubMed databases. Based on the inclusion and exclusion criteria and the reviewers’ consensus, we selected four studies for the systematic review. 133 patients with AC joint displacement were evaluated. Mean Age: approximately 31.90 years. 81.92 of these injuries occurred during sports practice. Surgical Procedures Used: titanium plates fixation (49 patients), arthroscopy (24), single tunnel technique (30) and coracoid sling technique (30). The results of the visual analog scale and Constant-Murley scores varied between the techniques used. Twenty-two complications after surgical treatment were identified. Conclusion: A significant variability of operative techniques can be used in the surgical approach of acromioclavicular dislocation, such as arthroscopy, single tunnel, coracoid sling and titanium plates. Although it presented excellent functional results compared to the other three tech

Antimicrobial resistance(AMR)is a growing phenomenon that poses a major public health challenge worldwide(Dhingra et al.2020;Antimicrobial Resistance Collaborators 2022).The selective pressure exerted in clinical settings has contributed to the longlasting successful dissemination of multidrug-resistant(MDR)Gram-negative bacteria in these environments(Chia et al.2020).

Journal of Biosciences and Medicines 2024年第2期12卷 50-59页

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.
