Recommendations to balance benefits and risks of thromboprophylaxis and to avoid central venous-access devices during first-line chemotherapy in men with metastatic germ cell tumors: The European Association Of Urology Testicular Cancer Panel Position in 2021

Recent randomized controlled trials have assessed the risksand benefits of thromboprophylaxis in ambulatory cancerpatients receiving chemotherapy and reported a relativerisk reduction of 30–60% in venous thromboembolic events(VTEs) but a doubling of bleeding risk [1–4]. Based on theseresults, the most recent American Society of ClinicalOncology clinical practice guideline update recommendsthromboprophylaxis with apixaban, rivaroxaban, or low-molecular–weight heparin (LMWH) for cancer patientswith a high risk of VTE and low risk of bleeding [5]. Patientswith metastatic germ-cell tumor (mGCT) were under-represented in all trials and thus it is not clear whether thisrecommendation applies to this group, although retrospec-tive data suggests similar efficacy of VTE prophylaxis

European Association of Urology Guidelines on Testicular Cancer: 2023 Update

Context: Each year the European Association of Urology (EAU) produce a document based on the most recent evidence on the diagnosis, therapy, and follow-up of testicular cancer (TC). Objective: To represent a summarised version of the EAU guidelines on TC for 2023 with a focus on key changes in the 2023 update. Evidence acquisition: A multidisciplinary panel of TC experts, comprising urologists, medical and radiation oncologists, and pathologists, reviewed the results from a structured literature search to compile the guidelines document. Each recommendation in the guidelines was assigned a strength rating. Evidence synthesis: For the 2023 EAU guidelines on TC, a review and restructure were undertaken. The key changes incorporated in the 2023 update include: new supporting text regarding venous thromboembolism prophylaxis in males with metastatic germ cell tumours receiving chemotherapy; quality of life after treatment; an update of the histological classifications and inclusion of the World Health Organization 2022 pathological classification; inclusion of the revalidation of the 1997 International Germ Cell Cancer Collaborative Group prognostic risk factors; and a new section covering oncology treatment protocols. Conclusions: The 2023 version of the EAU guidelines on TC include the highest available scientific evidence to standardise the management of TC. Better stratification and optimisation of treatment modalities will continue to improve the high survival rates for patients with TC. Patient summary: This article presents a summary of the European Association of Urology guidelines on testicular cancer published in 2023 and includes the latest recommendations for management of this disease. The guidelines are a valuable resource that may help patients in understanding treatment recommendations

Circadian Dependence of the Acute Immune Response to Myocardial Infarction

Circadian rhythms influence the recruitment of immune cells and the onset of inflammation, which is pivotal in the response to ischemic cardiac injury after a myocardial infarction (MI). The hyperacute immune response that occurs within the first few hours after a MI has not yet been elucidated. Therefore, we characterized the immune response and myocardial damage 3 hours after a MI occurs over a full twenty-four-hour period to investigate the role of the circadian rhythms in this response. MI was induced at Zeitgeber Time (ZT) 2, 8, 14, and 20 by permanent ligation of the left anterior descending coronary artery. Three hours after surgery, animals were terminated and blood and hearts collected to assess the immunological status and cardiac damage. Blood leukocyte numbers varied throughout the day, peaking during the rest-phase (ZT2 and 8). Extravasation of leukocytes was more pronounced during the active-phase (ZT14 and 20) and was associated with greater chemokine release to the blood and expression of adhesion molecules in the heart. Damage to the heart, measured by Troponin-I plasma levels, was elevated during this time frame. Clock gene oscillations remained intact in both MI-induced and sham-operated mice hearts, which could explain the circadian influence of the hyperacute inflammatory response after a MI. These findings are in line with the clinical observation that patients who experience a MI early in the morning (i.e., early active phase) have worse clinical outcomes. This study provides further insight on the immune response occurring shortly after an MI, which may contribute to the development of novel and optimization of current therapeutic approaches
