The diagnostic accuracy of ultrasound in assessing anterior cruciate ligament tears: a systematic review and meta-analysis.

Background: Advances in technology and affordability of ultrasound (US) have expanded its use in the evaluation of musculoskeletal injuries. However, US accuracy for diagnosing anterior cruciate ligament (ACL) injuries remains inconsistently reported in the literature.

Hypothesis/purpose: Systematically review the literature and perform a meta-analysis to statistically evaluate the accuracy of US in diagnosing ACL tears.

Utility of preoperative ultrasound in assessing the adequacy of autograft for anterior cruciate ligament reconstruction: a systematic review and meta-analysis.

Objective: Anterior cruciate ligament (ACL) reconstruction using tendon autograft requires imaging to evaluate graft adequacy. Ultrasound (US) offers an efficient adjunct to MRI; however, the utility of US is variable in prior literature and should be investigated. The primary aim of this study is to provide a statistical appraisal of literature assessing correlation of preoperative US measurements with intraoperative size of autografts during ACL reconstruction.

Pummelo fruit extract () reduces oxidative damage in peripheral blood of obese patients.

Objectives: To verify the level of oxidation of biomolecules in the peripheral blood of obese patients before and after incubation with the pummelo pulp extract at 25 mg/mL.

Methods: This investigation included 241 individuals, distributed across the following groups: control (n = 69; 30 men and 39 women); pre-obesity (n = 78; 29 men and 49 women); level I obesity (n = 62; 20 men and 42 women); and level II or III obesity (n = 32; 11 men and 21 women).

Results: TBARS and MN levels were significantly altered by incubation with pummelo extract in both genders and in all the groups according to their obesity level.

Acute kidney injury: a post-COVID-19 complication in children and adolescents.

Objective: To describe cases of acute kidney injury (AKI) in children diagnosed with COVID-19, associated risk factors, clinical aspects and outcome of cases.

Methods: Retrospective study, carried out in a pediatric hospital between March 2020 and September 2021, with patients with COVID-19 who were diagnosed with AKI, studying information present in medical records such as comorbidities, age, gender and use of nephrotoxic medications.

Results: We studied 40 cases, and male individuals were significantly more affected (62.
