Portable chest radiography is a valuable tool in the intensive care unit. However, the supine position causes superposition of anatomical structures resulting in less reliable detection of certain abnormalities. Recently, a portable digital tomosynthesis (pDTS) prototype with a modified motorized x-ray device was developed. We aimed to compare the diagnostic value of pDTS to standard bedside chest radiography in the diagnosis of a posterior pneumothorax. A modified motorized x-ray device was developed to perform 15 radiographic projections while translating the x-ray tube 25 cm (10 cm ramp up and 15 cm during x-ray exposure) with a total radiation dose of 0.54 mSv. This new technique of pDTS was performed in addition to standard bedside chest x-ray in a patient with a confirmed posterior hydropneumothorax. The images were compared with the standard bedside chest x-ray and computed tomography (CT) images by two experienced radiologists. The posterior hydropneumothorax previously identified with CT was visible on tomosynthesis images but not with standard bedside imaging. Combining the digital tomosynthesis technique with the portable x-ray machine could increase the diagnostic value of bedside chest radiography for the diagnosis of posterior pneumothoraces while avoiding intrahospital transport and limiting radiation exposure compared to CT.

E-commerce growth as experienced during the COVID-19 pandemic was only expected to occur by 2025–2030. Online shopping increased in intensity and diversity. At the same time, retailers diversified their operations and opened online channels, also in sectors that previously showed reluctance to make this shift. These evolutions resulted in an expansion of household freight in terms of volume, geography, and organisation. Hence, half a decade of innovation in the e-commerce sector was needed in the span of two years. This manuscript summarises the repercussions for household freight since the pandemic's start. Given that interactions between consumers, retailers, and logistics service providers drive the e-commerce system, this manuscript combines these different literatures into a holistic framework, going beyond traditional siloed research on last-mile logistics, retail strategies, or online shopping behaviour. We found that logistics has come to the forefront: logistics service providers now need to provide tailored services and come in direct contact with consumers. As a result, we need (i) to gain insights into the new geography and dynamics of household's freight origins and destinations; (ii) use this to re-examine existing relationships between consumer, retailer, and logistics service provider, and; (iii) assess the impact of more demanding consumers on the sustainability of the overall system.
