Abstract Although ample evidence has demonstrated that daytime napping is beneficial for health and cognitive performance, bedding for napping has not yet been scientifically investigated. In this study, we assessed the effect of a bean bag chair (BC), which would automatically adjust according to body shape and size, on daytime napping and physiological parameters related to sleep, such as electroencephalogram (EEG), electromyogram (EMG), and heart rate variability (HRV). Fourteen healthy participants were enrolled within the context of a randomized, single-blind, crossover study to evaluate the effects of a BC in comparison with those of a urethane chair manufactured to have a similar shape (UR). EEG analyses revealed no significant differences in sleep architecture or frequency components; however, a significant decrease was found in EMG recordings in the trapezius muscle, which represents the neck region (p = 0.024). Additionally, a significant main effect of bedding in the LF/RF ratio (F [1, 20] = 4.314, p = 0.037) was revealed. These results suggest that napping with a BC may provide a comfortable napping environment involving muscle relaxation and proper regulation of autonomic nervous function.

Abstract Bean bag guns were developed as a nonlethal means for law enforcement personnel to subdue individuals. The large surface area and lower velocities of the bean bag round theoretically result in transfer of most of the energy to the skin/subcutaneous tissue and minimize the likelihood of dermal penetration, thereby ‘stunning’ intended victims without causing injury to deeper structures. However, this technology has been associated with significant intra-abdominal and intrathoracic injuries, skin penetration and death. We present a 59-year-old man who sustained a penetrating thoracic injury from a bean bag gun. Although the bean bag was successfully removed, the patient developed a postoperative empyema requiring operative management. We discuss the unique aspects of thoracic trauma from bean bag ballistics as well as considerations in management of patients with this uncommon mechanism of injury.

Introduction. Cytophagic histolytic panniculitis (CHP) is a clinical disorder characterized by nodular panniculitis of the subcutaneous adipose tissue. It was first described in 1980 by Winkelmann. Histologically it is described as an infiltration of the adipose tissue by T- lymphocytes and phagocytic macrophages (also known as “bean bag cells”). Most of the cases are reported under the age of 50 and is a rare cause of panniculitis. We report a case of CHP in a young patient who presented to our emergency room (ER). Case Summary. A 39-year-old African American woman who presented to our hospital with lethargy, progressive confusion, and generalized rash involving both lower extremities of 1 week duration. She had a history of pancytopenia and focal proliferative and membranous lupus nephritis classes 3 and 5. Her physical examination was remarkable for bilateral lower extremity pitting edema and a desquamating rash on both of her legs. The Nicolsky sign was positive. She was noted to be hypotensive and was started on intravenous fluids and broad spectrum antibiotics. Routine laboratory tests revealed severe pancytopenia, with a hemoglobin of 3.9 g/dl, white blood cell count 600/ul, and platelet count of 11000/ul. Within an hour of arrival to the ER she developed acute respiratory failure. She was intubated and placed on mechanical ventilation. She developed shock requiring vasopressors. No imaging could be done due to her unstable condition. Four hours after her initial presentation she developed asystole and expired. Postmortem histopathology of the adipose tissue revealed CHP. Conclusion. CHP can be rapidly fatal. The treatment involves high dose of intravenous steroids and immunosuppressants such as cyclosporine.

Social comparisons differ in their diagnosticity—that is, in the extent to which their outcomes are attributable to sources internal versus external to the self. While logic suggests that people should give more credence to diagnostic than to nondiagnostic comparisons, research shows that people often overlook comparison diagnosticity, leading them to drawing inaccurate conclusions about themselves—a phenomenon known as diagnosticity neglect. Here I examine a process that may reduce diagnosticity neglect: psychological distance. Because psychological distance—and the mental abstraction it engenders—helps people to organize information hierarchically, it may allow people to better distinguish between diagnostic and nondiagnostic information. Four experiments, using two distinct tasks (a bean bag throwing game and an anagrams quiz) and two forms of psychological distance (social and hypothetical), confirm these predictions; a preregistered fifth experiment demonstrates their real-world consequences. Overall, this research highlights the power of psychological distance to reduce diagnosticity neglect.
