The applicability of forensic time since death estimation methods for buried bodies in advanced decomposition stages.

Estimation of the postmortem interval in advanced postmortem stages is a challenging task. Although there are several approaches available for addressing postmortem changes of a (human) body or its environment (ecologically and/or biochemically), most are restricted to specific timeframes and/or individual and environmental conditions. It is well known, for instance, that buried bodies decompose in a remarkably different manner than on the ground surface. However, data on how established methods for PMI estimation perform under these conditions are scarce. It is important to understand whether and how postmortem changes are affected under burial conditions, if corrective factors could be conceived, or if methods have to be excluded for respective cases. We present the first multi-methodological assessment of human postmortem decomposition carried out on buried body donors in Europe, at the Amsterdam Research Initiative for Sub-surface Taphonomy and Anthropology (ARISTA) in the Netherlands. We used a multidisciplinary approach to investigate postmortem changes of morphology, skeletal muscle protein decomposition, presence of insects and other necrophilous animals as well as microbial communities (i.e., microbiomes) from August to November 2018 associated with two complete body exhumations and eight partial exhumations. Our results clearly display the current possibilities and limitations of methods for PMI estimation in buried remains and provide a baseline for future research and application.

Psychiatric consultation-liaison interventions: recollection, perception and outcome.

OBJECTIVE: The aim of this study was to evaluate recollection, perception and outcome of psychiatric consultation in a general hospital. METHODS: 321 patients with three main diagnoses (substance use, affective, and adjustment disorders), who had been examined by consultation-liaison (C-L) psychiatrists within the past twelve months, initially took part in a telephone interview and were subsequently asked to complete and return questionnaires by mail. RESULTS: Response rates for the telephone interview were 75.4%, and 46.7% of patients returned the completed questionnaires. 86.0% of the patients were able to remember seeing the C-L psychiatrist and 43.3% recalled their diagnosis accurately. 70.5% stated that this contact had been helpful. 61.5% remembered being given a psychiatric after-care recommendation, and 43.5% of the patients stated that they either disregarded or prematurely discontinued after-care. CONCLUSIONS: Even though the perception of the consultation is generally positive, many patients are not able to retain the given information on diagnosis and treatment recommendation. To increase continuity of care and to better address patients' needs we altered our C-L structure.
