ISFG: recommendations regarding the use of non-human (animal) DNA in forensic genetic investigations.

Abstract: The use of non-human DNA typing in forensic science investigations, and specifically that from animal DNA, is ever increasing. The term animal DNA in this document refers to animal species encountered in a forensic science examination but does not include human DNA. Non-human DNA may either be: the trade and possession of a species, or products derived from a species, which is contrary to legislation; as evidence where the crime is against a person or property; instances of animal cruelty; or where the animal is the offender. The first instance is addressed by determining the species present, and the other scenarios can often be addressed by assigning a DNA sample to a particular individual organism. Currently there is little standardization of methodologies used in the forensic analysis of animal DNA or in reporting styles. The recommendations in this document relate specifically to animal DNA that is integral to a forensic science investigation and are not relevant to the breeding of animals for commercial purposes. This DNA commission was formed out of discussions at the International Society for Forensic Genetics 23rd Congress in Buenos Aires to outline recommendations on the use of non-human DNA in a forensic science investigation. Due to the scope of non-human DNA typing that is possible, the remit of this commission is confined to animal DNA typing only.

Water-stable fluorophores, produced by reaction with aldehyde solutions, for the histochemical localization of catechol- and indolethylamines.

Abstract: The properties of a new fluorescence histochemical method for arylethylamines based on reaction with a mixture of 4% formaldehyde and 0.5% glutaraldehyde in aqueous solution are described. At room temperature the aldehyde mixture produced a well-localized fluorescence reaction in tissues, which, when examined microscopically in aqueous solution, was sufficiently intense for fine terminal noradrenergic axons to be seen. If the tissue was subsequently dried, the fluorescence intensity increased. At the same time as inducing the fluorophores, the aldehyde mixture fixed the tissue to a standard well suited for electron microscopy. It thus proved possible to locate amine containing cells in the fluorescence microscope and subsequently examine their ultrastructure. In aqueous models, the aldehyde mixture formed fluorescent products with adrenaline, noradrenaline, dopamine, dopa, 5-hydroxytryptamine and 5-hydroxytryptophan, but not with histamine or octopamine. The fluorescence induced in the aldehyde mixture remained stable if the tissue was subsequently transferred to saline or distilled water and when it was dehydrated in ethanol and cleared with xylene, benzene, chloroform or acetone.

Bariatric Surgery Survey 2018: Similarities and Disparities Among the 5 IFSO Chapters.

Abstract: The 2018 IFSO Survey focused on similarities and disparities in the number and types of surgical and endoluminal interventions among the IFSO chapters occurred in the last decade. All IFSO Societies were asked to fill in the IFSO survey form on how many and which surgical and endoluminal interventions have been performed in the 2018. A special section was added, asking about the existence of national guidelines for bariatric and metabolic surgery, national recommendations for preoperative gastroscopy, type of reimbursement for bariatric/metabolic surgery, including for patients with BMI < 35 kg/m2. The trend analyses from 2008 to 2018 were also performed. Fifty-seven/65 (87.7%) IFSO Societies submitted completed forms. The American Society for Metabolic and Bariatric Surgery did not fill the IFSO survey form but provided an official report on the performed interventions. The total number of surgical and endoluminal procedures performed in 2018 in the world was 696,191. Sleeve gastrectomy (SG) remained the most commonly performed bariatric procedure (N = 386,096; 55.4%). Among the total reported bariatric/metabolic interventions, 604,223 (86.8%) were primary surgical and 29,167 (4.2%) primary endoluminal operations; 62,801 (9%) were revisional procedures. There was only a slight increase (10.317 procedures) in the total number of the reported bariatric interventions compared to the last IFSO survey. SG continues to be the most commonly performed operation since 2014. The one anastomosis gastric bypass (OAGB), currently the third most performed procedure after SG and Roux-en-Y gastric bypass (RYGB), continues to rise in popularity worldwide.
