Carcinogenicity testing in drug development: Getting it right

Paul Baldrick, Sanjay Jain

Summary: This study examines the regulatory process of carcinogenicity testing for pharmaceutical drugs, particularly through the Special Protocol Assessment (SPA) process of the US Food and Drug Administration (FDA). By analyzing 37 submission documents, it is found that the current regulatory interaction allows for drug approval and marketing, but there is room for improvement in study design and submission content.

The relationship between pellet size and shotgun dispersion patterns

Wim Kerkhoff, Keanu Maitimu, K. Dieter H. Pater, Markus A. de Jong

Summary: This study investigates the relationship between pellet size and shotgun dispersion patterns, finding that as pellet size decreases, the dispersion pattern of the shotgun increases, regardless of the material used (lead or steel). The difference in pattern sizes between consecutive pellet sizes is generally small, allowing for the use of cartridges with the next nearest shot number for muzzle-to-target distance determination.

Two case reports of fatal injuries sustained from tear gas guns loaded with pebbles as missiles

Hisham Zein-Elabdin, Maha A. Ghanem

Summary: This article reports two fatal injuries caused by tear gas guns using pebbles as ammunition. The two cases involved 19-year-old males, one with head trauma and the other with abdominal trauma. Autopsy reports showed that the relatively larger weight and size of the pebble projectiles were the main factors contributing to the severity of the injuries.

Comparison of all completed suicides in Frankfurt am Main (Hessen) before and during the early COVID-19 pandemic

S. C. Koelzer, M. A. Verhoff, S. W. Toennes, C. Wunder, M. Kettner, N. Kern, A. Reif, C. Reif-Leonhard, C. Schlang, I. Beig, V. Dichter, N. Hauschild, D. Lemke, S. Kersten, F. Holz

Summary: This study examined the impact of the COVID-19 pandemic on mental health by comparing completed suicides in Frankfurt am Main before and during the early pandemic. The results showed no significant increase in suicides during the early pandemic period. However, there was a higher proportion of male suicides and a shift in suicide methods for women. The study also found a trend towards more suicides among non-German nationals during the early pandemic.

A rapid and non-destructive identification for paper cup evidence based on shifted-excitation Raman difference spectroscopy and SOM clustering

Luchuan Tian, Hong Jiang, Xin Zhang

Summary: In this study, a classification model for paper cup samples was proposed, which integrated shifted-excitation Raman difference spectroscopy (SERDS) with self-organizing map (SOM) and Bayesian optimization-support vector machine (BO-SVM). The results showed that the SOM clustering effectively discerned samples with different fillers, while the BO-SVM model exhibited superior classification accuracy and performance in handling outliers.

Testing the accuracy of the DRNNAGE software for age estimation in a modern Greek sample

Leuteris Rizos, Nefeli Garoufi, Eustratios Valakos, Efthymia Nikita, Maria-Eleni Chovalopoulou

Summary: Estimating age-at-death from human skeletal remains is essential in forensic anthropology, but it is challenging due to the disparity between chronological and biological age, inter-individual variability in skeletal aging rate, and biases in available methodologies. This study tests a new method for skeletal age-at-death estimation using multiple anatomical traits and machine learning, with promising results. However, caution is needed with some variables, and the software showed better accuracy for older individuals. These findings emphasize the importance of cross-validation and population-specific methods in forensic anthropology.

The role of the right to life in respect of deaths caused by negligence in the healthcare context

Elizabeth Wicks

Summary: This article investigates whether a death caused by negligence in healthcare violates the right to life under Article 2 of the European Convention on Human Rights. It argues that the assumption of responsibility and nature of risk are key factors in determining the existence of an operational duty to save life.

The effect of photography training on the accurate representation of gunshot and stab wounds in autopsies: a comparative study

Alper Ozkok, Taner Akar, Birol Demirel

Summary: This study investigates the influence of photography training on the precision of autopsy photographs in depicting findings. The results show that trained medical photographers achieved higher accuracy in representing the findings compared to individuals without photography training. This is particularly noticeable in the assessment of stab wound length.

A computational approach to estimate postmortem interval using postmortem computed tomography of multiple tissues based on animal experiments

Zefang Shen, Yue Zhong, Yucong Wang, Haibiao Zhu, Ran Liu, Shengnan Yu, Haidong Zhang, Min Wang, Tiantong Yang, Mengzhou Zhang

Summary: This study aims to establish a multi-tissue machine learning model for estimating postmortem interval (PMI) using postmortem computed tomography (PMCT) data. By collecting PMCT data from various tissues, researchers utilized support vector machine, random forest, and K-nearest neighbors algorithms to build PMI estimation models, and a stacking model was used to improve accuracy. The results showed that the multi-tissue stacking model demonstrated strong predictive and generalization abilities.

Summary: In forensic medicine, studying the correlation between postmortem interval (PMI) and bone marrow antioxidant enzyme levels using ELISA, as well as the changes in histological structure of human bone marrow, can accurately estimate PMI. The level of antioxidant enzymes decreased significantly with increasing PMI, and histopathological examination showed gradual and regular morphological changes after death, indicating the value of PMI determination.
