The Phase 3 KEYLYNK-006 Study of Pembrolizumab plus Olaparib versus Pembrolizumab plus Pemetrexed as Maintenance Therapy for Metastatic Nonsquamous Non-Small-Cell Lung Cancer.

Background: Poly (ADP-ribose) inhibitors, including olaparib, upregulate programmed cell death ligand 1 (PD-L1), which may increase efficacy of anti-PD-(L)1 therapies.

Methods: In the phase 3 KEYLYNK-006 trial (NCT03976323), eligible adults with previously untreated metastatic nonsquamous NSCLC without targetable genetic alterations who had complete response (CR), partial response (PR), or stable disease (SD) following induction therapy with 4 cycles of pembrolizumab 200 mg Q3W, pemetrexed 500 mg/m , and carboplatin AUC5 or cisplatin 75 mg/m were randomized 1:1 to olaparib 300 mg orally twice daily or pemetrexed Q3W, both given with ≤31 cycles of pembrolizumab Q3W. Dual primary endpoints were progression-free survival (PFS) and overall survival (OS).

BLS courses for refugees are feasible and induce commitment towards lay rescuer resuscitation.

Background: High-quality Basic Life Support (BLS), the first step in the Utstein formula for survival, needs effective education for all kinds of population groups. The feasibility of BLS courses for refugees is not well investigated yet.

Methods: We conducted BLS courses including automated external defibrillator (AED) training for refugees in Austria from 2016 to 2019.

The impact of volume substitution on post-operative atrial fibrillation.

Background: Post-operative atrial fibrillation (POAF) represents a common complication after cardiac valve or coronary artery bypass surgery. While strain of atrial tissue is known to induce atrial fibrillating impulses, less attention has been paid to potentially strain-promoting values during the peri- and post-operative period. This study aimed to determine the association of peri- and post-operative volume substitution with markers of cardiac strain and subsequently the impact on POAF development and promotion.

An Extended Duration of the Pre-Operative Hospitalization is Associated with an Increased Risk of Healthcare-Associated Infections after Cardiac Surgery.

Nosocomial infections are a common complication in clinical practice with major impact on surgical success and patient outcome. The probability of nosocomial infections is rapidly increasing during hospitalization. Therefore, we investigated the impact of a prolonged pre-operative hospital stay on the development of post-operative infection.

CD4CD28 T Lymphocytes are Associated with the Development of Atrial Fibrillation after Elective Cardiac Surgery.

Post-operative atrial fibrillation (POAF) is postulated as a complex interaction of different pathogenic factors, suggesting inflammatory processes as a main trigger of this particular type of atrial fibrillation. Therefore, the study sought to assess the impact of cellular immunity on the development of POAF. Comparing patients developing POAF to individuals free of POAF the fraction of CD4CD28 T Lymphocytes was significantly higher in individuals developing POAF (11.
