Article Abstract
Although the outcome in younger adults with acute myeloid leukemia (AML) has improved, the benefit associated with standard intensive chemotherapy in older patients remains debatable. In this study, we investigated the incidence and the prognostic significance of genetic characteristics according to treatment intensity in patients aged 60 years or older. On the 495 patients of our cohort, (25.2%), (23.7%) and (16.8%) were the most frequent molecular mutations found at diagnosis. In this elderly population, intensive chemotherapy seemed to be a suitable option in terms of early death and survival, except for normal karyotype (NK) patients and those aged over 70 within the adverse cytogenetic/molecular risk group. The mutation was systematically associated with an unfavorable outcome, independently of the ratio. NK genotype tends to confer a good prognosis in patients treated intensively. Regarding minimal residual disease prognostic value, overall survival was significantly better for patients achieving a 4 log reduction (median OS: 24.4 vs. 12.8 months, = 0.013) but did not reach statistical significance for progression free survival. This retrospective study highlights that intensive chemotherapy may not be the most appropriate option for each elderly patient and that molecular markers may help treatment intensity decision-making.

Background And Importance: In the Czech Republic, paramedics are required to consult a physician before administering intravenous opioids, which may delay effective prehospital pain management. As paramedic competencies expand in Europe, it is important to evaluate the safety and efficacy of independent opioid administration in prehospital emergency care settings.
Objectives: To assess the safety and effectiveness of intravenous sufentanil administered independently by trained paramedics compared to administration following remote physician consultation in adult trauma patients.
Background: Angioimmunoblastic T-cell lymphoma (AITL) is a rare and aggressive form of peripheral T-cell lymphoma, accounting for 1 - 2% of non-Hodgkin lymphomas. Diagnosis is challenging, and there is no established standard first-line treatment. This case report highlights a rare progression from AITL to therapy-related acute myeloid leukemia (AML-pCT) following cytotoxic chemotherapy.

Background: Respiratory distress syndrome (RDS) is a leading cause of neonatal morbidity and mortality in low- and middle-income countries (LMICs). The feasibility and effectiveness of bovine versus porcine surfactants via less invasive surfactant administration (LISA) remain unstudied in LMICs. We compared clinical outcomes and cost-effectiveness of BLES versus poractant alfa in preterm infants with RDS managed with LISA.

Management of diabetes mellitus in hemodialysis is highly complex due to increased glycemic variability and hypoglycemic risk. The use of technologies applied to diabetes has been shown to improve glycemic control, however data in dialysis patients are limited. To describe the efficacy and safety of the minimed 780G AHCL system in a stable hemodialysis patient and during hospitalization in the Intensive Care Unit (ICU).

Background: This study assessed the prevalence and incidence of potentially inappropriate medication use for older patients undergoing surgery and its association with polypharmacy.
Methods: A retrospective, population-based cohort study with patients ≥ 65 undergoing first surgery at Landspitali-The National University Hospital of Iceland from 2005 to 2018. Participants were categorized by number of medications filled before and following their surgical episode into: non-polypharmacy (< 5), polypharmacy (5-9), and hyper-polypharmacy (≥ 10).
