Upper Crossed Syndrome (UCS), described by Vladimir Janda, is characterized by postural changes involving the cervical spine and trunk, leading to biomechanical limitations and cervicoscapulobrachial pain. This study proposes a mesotherapy protocol, termed the 8:1 block, to address cervicoscapulobrachialgia by targeting the scapulae and associated musculature. The scapula, central to shoulder girdle kinematics, often exhibits dyskinesis and muscular imbalances, notably the pattern referred to as scapular upper trapping (SUT).

Article Synopsis
  • The study highlights challenges in diagnosing sarcopenia among hemodialysis patients due to differing definitions from the EWGSOP2 and SDOC consensuses.
  • Similar prevalence rates for sarcopenia were found using both definitions, but there was a weak overall agreement in diagnoses between the two methods.
  • The results suggest that while there is some alignment in identifying severe sarcopenia cases, the discrepancies in diagnosing low muscle strength indicate a need for standardized approaches in clinical settings.

  • Pulmonary hypertension (PH) complicates mitral stenosis (MS), and this study investigates the role of pulmonary vascular resistance (PVR) and right atrial pressure (RAP) in predicting outcomes for patients with rheumatic MS undergoing percutaneous mitral balloon valvuloplasty (PMBV).
  • The study included 58 patients, dividing them based on PVR levels, and assessed outcomes like death and the need for further interventions during follow-up.
  • Results indicated that RAP was a significant independent predictor of adverse outcomes, while PVR did not demonstrate the expected prognostic significance, suggesting that RAP is more critical in monitoring these patients.

Standardized tests intend to reduce information asymmetry by providing a common and objective measure of students' academic performance. The basic assumption underlying standardized testing is that differences in student performance on standardized tests should be attributed primarily to differences in the quality of education received by students. However, there is evidence that environmental factors can affect standardized test scores, which may result in anomalous observations or outliers that show a distortion of student performance.

This essay provides a theoretical reflection on the challenges of meeting the Sustainable Development Goals of the 2030 Agenda, considering its motto of "leave no one behind". To exemplify these challenges, we discuss noncommunicable diseases (NCDs), one of the main issues on the global health agenda before the COVID-19 pandemic, and the political and economic dimensions that determine their presence and global spread. After a brief overview of NCDs, the text seeks to answer three questions: In "Leaving no one behind?" we list some themes to reflect on how and who has historically been left behind, delving a little deeper into the examples in "Who has been left behind in the world?" and "Who has been left behind in Brazil?".

Glutathione (GSH), a tripeptide synthesized intracellularly, serves as a pivotal antioxidant, neutralizing reactive oxygen species (ROS) and reactive nitrogen species (RNS) while maintaining redox homeostasis and detoxifying xenobiotics. Its potent antioxidant properties, particularly attributed to the sulfhydryl group (-SH) in cysteine, are crucial for cellular health across various organelles. The glutathione-glutathione disulfide (GSH-GSSG) cycle is facilitated by enzymes like glutathione peroxidase (GPx) and glutathione reductase (GR), thus aiding in detoxification processes and mitigating oxidative damage and inflammation.
