Objectives: This study aimed to evaluate the levels of TNF-α, PGE, RANKL, RANK, OPG, the markers of periimplant bone loss in peri-implant crevicular fluid obtained around standard and extra short implants. Moreover, the levels of putative oral pathogens were investigated in the submucosal biofilm samples.
Material And Methods: The implants were divided into two groups according to their lengths: standard (≥8 mm) and extra short (4 mm). A total of 60 implants were researched in 30 patients. The probing depth (PD), clinical attachment level (CAL), presence of bleeding on probing (BOP), 3-year survival rate (CSR), and bone loss (BL) were measured.
Results: No statistically significant difference was found in the values of PD, CAL, BOP, CSR, and BL between the groups (P> 0.05). Total amounts of PGE, TNF-α, RANKL, RANK, OPG, and RANKL/OPG were not statistically significantly different between the groups (P> 0.05). The abundance , , , , and was compared between the groups and the results were not statistically significant (P> 0.05).
Conclusion: The results of this study suggested that PGE, TNF-α, RANKL, RANK, OPG, and RANKL/OPG in PICF, as well as microbiological parameters in submucosal biofilms, were similar between standard (≥8 mm) and extra short (4 mm) implants. Therefore, the implant length does not seem to influence the bone loss, levels of osteoimmunological and microbiological markers in the peri-implant tissues and survival rates.

Background: Kirschner wire (K-wire) and intramedullary (IM) screw fixation are accepted techniques for treatment of unstable proximal phalanx fractures, but comparative reports are lacking. This study aimed to evaluate early clinical outcomes following treatment with K-wire or IM fixation.
Methods: A retrospective review of all proximal phalanx fractures treated surgically at a single center by multiple surgeons was performed from May 1, 2019 to March 1, 2024.
Study on the linkage mechanism between key strata fracture in overburden and surface subsidence during caving mining in extra-thick coal seams.

Caving mining in extra-thick coal seams induces large-scale overburden movement, leading to more intense fracture processes in key strata, more significant surface subsidence, and frequent dynamic disasters in mines. This study, using the N34-2 caving face of the 17th coal seam at Junde Mine as a case study, aims to investigate the time-varying linkage mechanism between surface subsidence, microseismic characteristics, and fracture scales of the overburden's key strata under such mining conditions. Based on Timoshenko's theory, a bearing fracture mode for the overburden's key strata is proposed, and corresponding fracture criteria are established.

Background: Thick fetal corpus callosum (CC) is a rare finding and its significance in isolation is not clear. In this retrospective study, we aim to gain insight into the microarchitecture of CC in a cohort of fetuses with thick and short CC (isolated or associated with mild extra-/intracranial abnormalities) as seen on ultrasound (US), by using prenatal magnetic resonance (MR) diffusion tensor imaging (DTI) with fiber tractography, thereby allowing better characterization for postnatal prognosis.
Methods: Twelve fetuses met the inclusion criteria on US.

When a difficult airway is anticipated, awake tracheal intubation can be considered. Usually, low doses of sedatives are administered during this procedure for minimal sedation and anxiolysis, such as midazolam and remifentanil. The newly developed ultra-short-acting benzodiazepine remimazolam has a pharmacokinetic profile that is more suitable for titration during awake tracheal intubation than the long-acting midazolam.

The scheme utilizes DM-OFDM-IM, where subcarriers within each subblock are divided into two groups, each modulated by distinct signal constellations. DM-OFDM-IM leverages the sequential information from the modulated constellation to transmit extra information, leading to a substantial enhancement in spectral efficiency.
