Article Synopsis
  • Acute kidney injury (AKI) occurs in 20-30% of cardiac surgery patients using cardiopulmonary bypass (CPB), and it's linked to hemolysis caused by the CPB process.
  • The release of cell-free hemoglobin leads to oxidative stress, reduced nitric oxide levels, and inflammation, which all contribute to kidney damage.
  • New treatments like haptoglobin, nitric oxide, and antioxidants show promise in mitigating hemoglobin-related toxicity and preventing AKI, with encouraging clinical evidence suggesting these approaches could be effective.

(1) Background: Between the beginning of the coronavirus pandemic and summer 2022, we distinguished four pandemic waves, with different characteristics of the affected patients. This study investigated the impact of patient characteristics on the outcome of inpatient pulmonary rehabilitation (PR). (2) Methods: Using a prospective approach, the characteristics of post-acute COVID-19 patients of the different waves who participated in inpatient PR were compared based on their assessments and results collected as part of PR (Cumulative Illness Rating Scale (CIRS), six-minute walk test (6-MWT), Pulmonary Function Testing (PFT), and Functional Independent Measurement (FIM).

Purpose: We investigated whether a 4-wk period of respiratory muscle endurance training (RMET) or respiratory muscle sprint interval training (RMSIT) would lead to an attenuation of inspiratory muscle and quadriceps fatigue after a bout of high-intensity cycling compared with a placebo intervention (PLAT), as predicted by the respiratory metaboreflex model.

Methods: Thirty-three active, young healthy adults performed RMET, RMSIT, or PLAT. Changes in inspiratory muscle and quadriceps twitches in response to a cycling test at 90% of peak work capacity were assessed before and after training.

Objectives: As females have been hypothesized to have more fatigue resistant inspiratory muscles, this study aimed to compare the development of inspiratory and leg muscle fatigue between males and females following high-intensity cycling.

Design: Cross-sectional comparison.

Methods: 17 healthy young males (27 ± 6 years, V̇O 55 ± 10 ml・min・kg) and females (25 ± 4 years, V̇O 45 ± 7 ml・min・kg) cycled until exhaustion at 90% of the peak power output achieved during an incremental test.

Background: Standard treatment options for patients with stage IIA or stage IIB seminoma include either para-aortic and pelvic radiotherapy or three to four cycles of cisplatin-based combination chemotherapy. These options result in 3-year progression free survival rates of at least 90%, but bear risks for acute and late toxic effects, including secondary malignancies. We tested a novel approach combining de-escalated chemotherapy with de-escalated involved node radiotherapy, with the aim of reducing toxicity while preserving efficacy.
