The medico-legal interpretation of diatom findings for the diagnosis of fatal drowning: a systematic review.
Int J Legal Med
January 2025
Swedish National Board of Forensic Medicine, Retzius v. 5, 171 65 Stockholm, Stockholm, 171 65, Sweden.
The diagnostic use of the diatom test for drowning has been under investigation for more than a century. Despite continuing research, its true usefulness remains controversial and under debate. Data regarding the extent to which diatoms can penetrate the lungs and other organs of drowning victims are conflicting; similar discrepancies exist as to the presence of diatoms in the organs of living individuals; and as to the occurrence of postmortem (PM) contamination.

Department of Surgery, Maastricht University Medical Center, Maastricht.
Background: The evolution of endoscopic surgery has introduced a multitude of instruments, available in both disposable and reusable variants, influencing practices across various surgical specialties. Instrument selection is complex, considering individual preferences and institutional factors such as costs, instrument performance, and factors related to cleaning and sterilization. Notably, environmental sustainability has gained prominence due to the threat of climate change.

J Pediatr Orthop

Department of Orthopaedic Surgery, Nationwide Children's Hospital.
Background: Biopsy is an essential part of proper diagnostic workup in pediatric bone sarcomas impacting surgical planning, chemotherapeutic treatments, and prognostic determination. Two main biopsy techniques are currently used: closed biopsy (core needle or fine needle aspiration) and open biopsy. Historical oncologic teaching is for resection of the biopsy tract with the tumor specimen due to the theoretical risk for biopsy tract tumor contamination; however, this can restrict surgical planning and increase morbidity.

Department of Wildlife Ecology and Conservation, University of Florida, Gainesville, FL, USA.
Songbird reproductive success can decline from consuming mercury-contaminated aquatic insects, but assessments of hydrologic conditions influencing songbird mercury exposure are lacking. We monitored breast feather total mercury (THg) concentrations and reproductive success in the U.S.

State Key Laboratory of Swine and Poultry Breeding Industry, College of Animal Science, South China Agricultural University, Guangzhou 510642, China.
Glyphosate-based herbicide (GBH), a feed contaminant, has been proven to impair the growth and development of humans and animals. Previous research has revealed that maternal toxin exposure during pregnancy could cause permanent fetal changes by epigenetic modulation. However, there was insufficient evidence of the involvement of DNA methylation in maternal GBH exposure-induced intestinal health of offspring.
