Summary: Microbial communities undergo successional changes during decay and decomposition, providing valuable insights for estimating the postmortem interval (PMI). The abundance of bacterial communities decreases over time, and there are significant differences in microbial diversity before and after rupture. Using genus as a biomarker can help estimate the PMI.

Summary: This study provides reference concentrations of elemental intoxications in postmortem cases and demonstrates the impact of sample contamination and storage time on the concentrations of elements in blood and urine. It fills a gap between antemortem population studies and small case series or reports of elemental intoxications.

Summary: This study presents a detailed interpretation of toxicological results from 136 cases analyzed by the Bureau of Legal Medicine at the University of Milan. The majority of cases (74.3%) showed positive results, with cocaine, diazepam, morphine, and ethanol being the main substances detected. Specific profiles of individuals who died from acute intoxication or other causes were identified. The importance of toxicological data in forensic sciences is confirmed by this study.

Summary: This systematic review evaluates the application and performance of AI technology in postmortem interval (PMI) prediction. The studies show that machine learning models have demonstrated accuracy, precision, and the ability to overcome human errors and bias in PMI estimation. However, the research is limited to small, selected populations, and further large-scale population-based studies are needed to fully understand the integration of ML models.

Summary: The method developed for the detection of lidocaine in postmortem whole blood is rapid, sensitive, and robust, with a dynamic linear range from 100 to 6000 ng/mL and high accuracy. It was successfully applied to real blood samples from cases where CPR was attempted, showing blood concentrations ranging from 0.21-0.96 μg/mL.

Summary: Forensic Odontology identification compares dental datasets before and after death, and is widely accepted as a primary identifier. This study aimed to determine if there are differences in identification outcomes between postmortem dental data collected from computed tomography (CT) and conventional postmortem examination. The results showed that CT examination resulted in similar or less certain identification outcomes compared to conventional examination, and the differences were driven by the quality of antemortem and postmortem datasets rather than inaccuracies in charting from CT.

Summary: Postmortem metabolomics can be used to differentiate causes of death, particularly those related to hypoglycemia. This study focused on identifying a metabolic fingerprint for insulin intoxication deaths and screening for unknown hypoglycemia-related deaths. The results showed distinct metabolic differences between insulin intoxication deaths and other groups.

Summary: Knowledge of the decomposition of vertebrate animals has advanced considerably in recent years, but has not been fully incorporated into research or models of the postmortem interval (PMI). We propose using recent advances in decomposition theory to guide forensic research and understanding of the PMI. To improve in this area, a conceptual framework is introduced that highlights the multiple interdependencies affecting decay rates and calls for a multidisciplinary approach and an adaptive research cycle.

Summary: The study investigates the principles governing microbial community succession during decomposition of rat and human corpse, and explores their potential use for post-mortem interval (PMI) estimation. The results demonstrate that microbial succession is predictable and can be developed into a forensic tool for estimating PMI.

Summary: This study compared the frequency of postmortem ethanol formation in different body fluids and evaluated the interpretational value of EtS and PA results. The findings suggest that EtS and PA analysis can improve the diagnostic accuracy of ethanol in postmortem cases.

Summary: In the field of forensics, the estimation of age at death based on the height of root dentin transparency in adult teeth is commonly used. However, its consistency in archaeological material is uncertain. This study aimed to observe the structural modifications of sclerotic dentin in teeth with different postmortem intervals.

Summary: This study investigated temporal changes in bacterial community structure associated with porcine skeletal remains in a freshwater lake, revealing significant differences between rib and scapulae-associated bacterial communities. Alpha-diversity increased with accumulated degree days (ADD) for each bone type, while beta-diversity bacterial community structure changed significantly with ADD, explained by environmental parameters and functional pathways. Models utilizing family-level taxa allowed for the prediction of postmortem submersion interval (PMSI) with reasonable accuracy.
