Characteristics of Deaths With Evidence of Pathological Hoarding in Cook County 2017 to 2018.

Hoarding disorder was recently recognized as an independent diagnosis; it is characterized by the accumulation of objects causing a functional impairment and is commonly associated with increased risk of injury or death. Limited data exist about deaths of persons found in hoarding environments. This study investigated the characteristics and circumstances surrounding deaths found in "hoarding" environments.

Neoplastic embolization to systemic and pulmonary arteries.

Objective: Arterial neoplastic emboli are uncommon, accounting for <1% of thromboemboli in the current literature. Nonetheless, this event may be associated with significant morbidity and mortality. Herein, we report a series of 11 cases of arterial neoplastic emboli from a single tertiary care center along with a comprehensive review of the literature to date.

Healed Fracture of Superior Horn of Thyroid Cartilage in Autoerotic Asphyxia: An Indication of Prior Activity? A Case Report Utilizing 3D Scanning and Printing of the Larynx.

Evidence of prior autoerotic asphyxia is often difficult to establish due to the decedent's efforts to hide the activity from others. In this case report, we suggest that a healed fracture of the thyroid cartilage is indicative of prior autoerotic asphyxia activity. The decedent was a 45-year-old man who was found unclothed on the floor of his bedroom with a belt ligature around the neck.

The invasion of southern South America by imported bumblebees and associated parasites.

The Palaearctic Bombus ruderatus (in 1982/1983) and Bombus terrestris (1998) have both been introduced into South America (Chile) for pollination purposes. We here report on the results of sampling campaigns in 2004, and 2010-2012 showing that both species have established and massively expanded their range. Bombus terrestris, in particular, has spread by some 200 km year(-1) and had reached the Atlantic coast in Argentina by the end of 2011.

Pollen mixing in pollen generalist solitary bees: a possible strategy to complement or mitigate unfavourable pollen properties?

Generalist herbivorous insects, which feed on plant tissue that is nutritionally heterogeneous or varies in its content of secondary metabolites, often benefit from dietary mixing through more balanced nutrient intake or reduced exposure to harmful secondary metabolites. Pollen is similarly heterogeneous as other plant tissue in its content of primary and secondary metabolites, suggesting that providing their offspring with mixed pollen diets might be a promising strategy for pollen generalist bees to complement nutrient imbalances or to mitigate harmful secondary metabolites of unfavourable pollen. In the present study, we compared larval performance of the pollen generalist solitary bee species Osmia cornuta (Megachilidae) on five experimental pollen diets that consisted of different proportions of unfavourable pollen diet of Ranunculus acris (Ranunculaceae) and favourable pollen diet of Sinapis arvensis (Brassicaceae).
