The rapid growth of urban instant delivery, facilitated by digital platforms and characterized by on-demand, short-term, task-based labor, has raised concerns about safety, particularly with the increasing frequency of instant delivery crashes (IDCs). This study addresses knowledge gaps in understanding injury patterns and risk factors associated with IDCs. Utilizing data extracted from judicial verdicts on IDC disputes in China, encompassing demographic, contextual, crash, and injury information, the research employs ordered logit regression to identify significant factors affecting injury patterns, the number of injuries per person (IPP), and injury severity. ⋯ Major injuries among victims emphasize potential long-term consequences and associated costs. The significance of gender, age, and risk behavior as determining factors highlights the need for targeted safety interventions. These findings offer crucial insights for stakeholders, guiding the formulation of precise safety measures and informed policy initiatives within the dynamic landscape of instant delivery safety.

Proximal femoral fractures are a major public health issue due to an increasing ageing population, with an important impact on patients' quality of life. This study was designed by the Authors through a national survey with the purpuse to investigate the italian experience and practice about management and perioperative/operative trends of intracapsular proximal femoral fractures (PFF). In February-March 2022 a national survey was submitted online to the members of SIOT (Società Italiana Ortopedici e Traumatologi) and SIDA (Società Italiana dell'Anca) societies. ⋯ The Survey was completed by 372 surgeons; answers reported were often in accordance with the literature and national and international guidelines, with, on the other hand, important controversies regarding preoperative management (radiological studies and preoperative planning), some surgical indications and choice of stem fixation. Management of proximal femoral fractures is not always clear and univocal; it is mandatory to produce a diagnostic-therapeutic process supported by scientific evidence. In this context the SIOT Guidelines 2021 offer a real help for the surgeon managing a PPF.

The social and financial burdens of the operative environment remains to be a major problem in modern society. We analyse the impact of the introduction and application of a perioperative cloud system that cross-analyzes the pre-/intraoperative risks to minimize surgical time and maximize operation theater efficiency through improved planning. ⋯ A data filtering algorithm-assisted cloud system can be a reliable way to facilitate the planning of operating theater schedules. Patient stratification according to BMI and surgeon years of experience seems to affect intraoperative duration significantly, and the understanding of the risks and intraoperative steps has the potential to forecast surgeries with high precision.

Proximal femoral fractures in elderly women are a major cause of morbidity and mortality worldwide and a public health concern. Although pharmacological therapies have shown potential in improving bone mineral density (BMD) and decreasing fracture risk, the current research effort is focused on developing a procedure that can ensure both immediate and long-term efficacy. ⋯ The results of this procedure have shown a significant and sustainable long-term increase in the proximal femur BMD and consequently in bone strength, thereby improving the femoral neck's resistance to compression and distraction forces that may result in fall-related fractures. A preliminary case series of ten women, suffering from intertrochanteric fracture and contralateral proximal femur severe osteoporotic bone loss, who underwent a combined procedure of proximal femoral nailing and AGN1 local osteo-enhancement procedure, has been developed over the course of a year of clinical and radiological data collection.

Fracture healing is a complex biological process that begins soon after a fracture has occurred. Whereas the role of vitamin D status on the maintenance of bone health is well established, the clinical effects of vitamin D deficiency in the healing of distal humeral fractures are less well explored. This study examines the role of vitamin D serum levels in distal humeral fractures (C2, C3) managed with open reduction and double plate fixation, by comparing its concentration in patients with or without radiographic signs of fracture healing and in control subjects. Our hypothesis is that 6 months from treatment vitamin D levels will be different between the groups of patients. ⋯ Vitamin D is primarily involved in the stages of hard callus formation and remodelling. It also has several functions that affect the early stages of fracture healing. Vitamin D influences the cellular process of bone healing, although the underlying mechanism is still partly unclear. It would be useful to determine the vitamin D status of fracture patients at admission and to start supplementation, with periodic checks, to foster the consolidation phase. Although vitamin D is clearly not the only factor influencing the consolidation of a surgically treated distal humerus fracture, its concentration can easily be determined and managed. Our data suggest that vitamin D levels should be determined at admission and that fracture patients with low concentrations should be started on vitamin D supplementation.
