Abstract
PURPOSE Electric scooters (e-scooters) are an increasingly popular method of transportation worldwide. However, there are concerns regarding their safety, specifically with regards to orthopaedic injuries. We aimed to investigate the overall burden and financial impact on orthopaedic services as a result of e-scooter-related orthopaedic injuries. METHODS We retrospectively identified all e-scooter-related injuries requiring orthopaedic admission or surgical intervention in a large District General Hospital in England over a 16-month period between September 2020 and December 2021. Injuries sustained, surgical management, inpatient stay and resources used were calculated. RESULTS Seventy-nine patients presented with orthopaedic injuries as a result of e-scooter transportation with a mean age of 30.1 years (SD 11.6), of which 62 were males and 17 were females. A total of 86 individual orthopaedic injuries were sustained, with fractures being the most common type of injury. Of these, 23 patients required 28 individual surgical procedures. The combined theatre and recovery time of these procedures was 5500 min, while isolated operating time was 2088 min. The total cost of theatre running time for these patients was estimated at £77,000. A total of 17 patients required hospital admission under Trauma and Orthopaedics, which accounted for total combined stay of 99 days with a mean length of stay of 5.8 days. CONCLUSION While there are potential environmental benefits to e-scooters, we demonstrate the risks of injury associated with their use and the associated increased burden to the healthcare system through additional emergency attendances, frequent outpatient clinic appointments, surgical procedures, and hospital inpatient admissions.

Abstract
PURPOSE The biological association between chronic lymphocytic thyroiditis (CLT) and differentiated thyroid cancer (DTC) has not been elucidated yet. The aim of the study was to assess whether the presence of CLT exerts any influence on clinical or histological presentation of DTC. METHODS Nine hundred and seven consecutive patients with DTC treated in the years 1998-2016 were divided into two groups according to the presence or absence of concomitant CLT. The statistical differences were analysed. RESULTS Out of 907 patients included in the study, 331 were diagnosed with DTC and CLT (studied group), while 576 patients with DTC but without CLT constituted a control group. The distribution of papillary and follicular thyroid cancer did not differ. In CLT group, the prevalence of pT1 was greater than for pT2-pT4 DTC (P = 0.0003; OR = 1.69, 95% CI 1.27-2.24) compared to controls (68.3 vs. 56.1%, respectively). The presence of multifocal lesions was similar. The thyroid capsule infiltration without extrathyroidal invasion (P < 0.0001; OR = 0.21, 95% CI 0.14-0.31) was more frequent in the studied group, unlike extracapsular invasion, which was significantly more often present in patients with DTC but without CLT (P = 0.004; OR = 1.66; 95% CI 1.17-2.34) as well as nodal involvement (P = 0.048; OR = 0.65, 95% CI 0.42-0.99). CONCLUSIONS The collected data indicate a protective role of CLT in preventing the spread of the DTC. The presence of CLT might limit tumour growth to the primary site.

Abstract
By using single-molecule multiparameter fluorescence detection, fluorescence resonance energy transfer experiments, and newly developed data analysis methods, this study demonstrates directly the existence of three structurally distinct forms of reverse transcriptase (RT):nucleic acid complexes in solution. Single-molecule multiparameter fluorescence detection also provides first information on the structure of a complex not observed by x-ray crystallography. This species did not incorporate nucleotides and is structurally distinct from the other two observed species. We determined that the nucleic acid substrate is bound at a site far removed from the nucleic acid-binding tract observed by crystallography. In contrast, the other two states are identified as being similar to the x-ray crystal structure and represent distinct enzymatically productive stages in DNA polymerization. These species differ by only a 5-A shift in the position of the nucleic acid. Addition of nucleoside triphosphate or of inorganic pyrophosphate allowed us to assign them as the educt and product state in the polymerization reaction cycle; i.e., the educt state is a complex in which the nucleic acid is positioned to allow nucleotide incorporation. The second RT:nucleic acid complex is the product state, which is formed immediately after nucleotide incorporation, but before RT translates to the next nucleotide.
