Application of Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) in forensic science - A review.

The paper presents the possibilities of using the ToF-SIMS technique in the examination of a range of samples as forensic evidence. These include the analysis of documents, the examination of writing media, the analysis of crossing lines, the analysis of cosmetics, hair analysis, the examination of automobile paints, and the analysis of fingerprints and their contamination with exogenous substances. The advantages and disadvantages of this method were analysed with reference to the information that any forensic investigator would wish to obtain when examining highly significant evidence.

Does the Coronary Artery Bypass Grafting Impact the Survival of Men and Women Equally Compared to General Population? Results from KROK Registry and Polish Central Statistical Office.

The aim of this study was to evaluate the impact of coronary bypass surgery (CABG) on long-term mortality, comparing survival rates to those of the general population in Poland. The study was based on the Polish National Register of Cardiothoracic Surgical Procedures (KROK). Between January 2009 and December 2019, 133,973 patients underwent CABG.

Poorer Nurse Staffing in Black-Serving Hospitals.

Background: Patients in hospitals that serve disproportionately patients of Black race have worse outcomes than patients in other hospitals, but the modifiable nursing factors that may contribute to such disparities have not been explored.

Objective: The study objective was to examine whether nurse staffing differs in hospitals that serve predominantly patients of Black race (Black-serving hospitals) as compared to other hospitals.

Methods: A cross-sectional correlational design using a nurse survey in a national hospital sample was used to fulfill the study objective.

Performance of EuroSCORE II in Octogenarians Undergoing Coronary Artery Surgery (from the KROK Registry).

Octogenarians constitute the fastest-growing segment within contemporary cardiac surgery, yet precise risk assessment in this age group remains challenging. This study aimed to evaluate EuroSCORE II reliability in octogenarians undergoing isolated coronary surgery and to create an adjustment formula if necessary. All octogenarians who had isolated coronary surgery in Poland from January 2012 to December 2023, recorded in the Polish National Registry of Cardiac Surgical Procedures (KROK registry), were retrospectively assessed.

Association between iron deficiency anemia and severe maternal morbidity: A retrospective cohort study.

Purpose: We examined the association between iron deficiency anemia (IDA) and severe maternal morbidity (SMM) during delivery and up to 1-year postpartum.

Methods: In a retrospective cohort study across 3 states, we computed adjusted relative risks (aRR) for SMM comparing individuals with IDA versus those without, using modified Poisson regression models.

Results: Among 2459,106 individuals, 10.
