Observational Study
Prognostic value of perioperative high sensitivity troponin in patients undergoing hip and knee arthroplasty.
The authors conducted a prospective observational study to investigate the prognostic value of high-sensitivity Troponin I (hs-TnI) in the short- and long-term periods after orthopedic surgery, including Total Hip and Knee Arthroplasty (THA and TKA, respectively), in a tertiary orthopedic center in Brazil. Perioperative Myocardial Injury (PMI) was defined as an absolute increase in hs-TnI of ≥ 26 ng/L above preoperative values. The primary endpoint was all-cause mortality assessed at 30 days and 18 months after surgery. ⋯ Based on composite outcomes in short and long-term periods, the RRs were 16.2 (95 % CI 2.7-96.5) and 7.7 (95 % CI 2.2-26.6), respectively. PMI was associated with all-cause mortality after 18 months and increased risk for a composite outcome (Hazard Ratio [HR = 3.97], 95 % CI 1.13-13.89 and HR = 5.80, 95 % CI 1.93-17.45, respectively). Patients with PMI who underwent THA or TKA presented worse short- and long-term prognoses compared to those without PMI.

Impact of the COVID-19 pandemic on cataract surgeries in Brazil: A retrospective study.
This study aimed to describe the behavioral patterns of data on cataract surgery performed in the Brazilian public health system before, during, and after the COVID-19 outbreak and estimate the setbacks generated by the pandemic to guide public policies. ⋯ The COVID-19 pandemic did not worsen the situation of cataract blindness in Brazil due to the efficacy of the measures taken by the government in resuming elective surgeries. However, the auhtors recommend that the distribution of resources for cataract surgeries should consider regional discrepancies based on epidemiological data.

Observational Study
The profile of adolescents assisted by the emergency department of a Brazilian private tertiary hospital.
Adolescents represent an important demographic percentage in the studied population and in Emergency Departments (ED). It is imperative that health professionals and services are prepared to address this population. This work aims to characterize adolescents at the ED of a Brazilian private tertiary hospital. ⋯ In this study, flu-like symptoms were the single main reason for adolescents to search for immediate health care, in every age subgroup and gender, but represented a small risk for hospital admission. Limb trauma was more common in younger male teenagers. Acute abdominal pain and trauma were the most frequent causes of hospital admissions. There was a significant and strong correlation between age and both admission rate and severity.

To investigate the reasons for a second surgery after Percutaneous Endoscopic Surgery (PES) for lumbar spinal stenosis and to provide references for the choice of indications and appropriate surgical approach. ⋯ Severe hyperplasia, obscure anatomic structure, lumbar instability, and nerve injury are the common reasons for a second surgery after PES for lumbar spinal stenosis. Appropriate indications and surgical approaches can be chosen based on the patient's situations and technical conditions.

The purpose of the present study was to examine the association of oxidative stress markers with sarcopenia in the general United States population under the age of 60. ⋯ We demonstrated a nonlinear association between markers of oxidative stress and sarcopenia. The need to focus more on levels of oxidative stress in the body could provide better prevention strategies for sarcopenia.
