AI Article Synopsis
- Horizontal bone loss following tooth extraction often requires reconstruction, and this study aimed to evaluate horizontal alveolar bone status in both partially and completely toothless patients using cone-beam computed tomography (CBCT).
- The analysis involved 1516 CBCT scans from 1404 adults, classifying horizontal bone defects into four categories (HAC 1 to HAC 4), with a notable distribution among partially edentulous patients showing mostly HAC 1 and less severe conditions.
- Results indicated that completely edentulous patients had a higher prevalence of severe conditions (HAC 3 and HAC 4), suggesting they often lack cancellous bone, particularly in HAC 4, compared to those who are partially edentulous.
Article Abstract
Horizontal bone loss after tooth extraction is a common finding that demands bone reconstruction in various cases. The aim of this study was to assess the horizontal alveolar status in partially and completely edentulous patients using cone-beam computed tomography (CBCT). In total, 1516 CBCT scans of 1404 adult patients were analyzed. Assessment of the images was performed in accordance with the previously published horizontal alveolar change (HAC) classification, which categorizes horizontal bone defects into four classes: HAC 1, HAC 2, HAC 3 and HAC 4 (from the least severe to the most severe condition). Analysis of 1048 scans from partially edentulous patients presented a distribution of 63.55%, 22.14%, 13.36% and 0.95% in HAC 1, HAC 2, HAC 3 and HAC 4, respectively. Analysis of 468 scans from completely edentulous patient images presented a distribution of 19.87%, 28.63%, 41.67% and 9.83% in HAC 1, HAC 2, HAC 3 and HAC 4, respectively. Based on these results, as in HAC 4, no cancellous bone was found between the cortical buccal and lingual/palatal bone plates, it seems reasonable to state that the absence of cancellous bone is higher in completely edentulous patients than in partially edentulous patients. Therefore, the absence of cancellous bone seems to be higher in completely edentulous than in partially edentulous patients.

Background: Microglia responses to Aβ and tau pathology and the dysregulation of the microglial role in synaptic function may determine the onset and course of Alzheimer's disease (AD). While significant work has been performed in mouse models, we still lack a complete understanding of physiological and pathological microglial states and functions in human AD brain.
Method: For immunoblotting of brain homogenates against multiple microglial markers, and flow cytometry (FC) analysis of synaptosomal fractions (SNAP25/CD47/Aβ(10G4)/phospho-tau(AT8)), 49 cryopreserved human parietal cortex samples were categorized into four groups: low pathology control (LPC), high Aβ control (HAC), high pathology control (HPC), and AD.

Hidradenocarcinoma (HAC) is a rare neoplasm that typically occurs in the head and neck region but seldom affects the chest wall. Histopathology and immunohistochemistry remain essential for diagnosing HAC, although their clinical utility in determining metastasis can be limited. Given the pathological rarity and histopathological heterogeneity of HAC, we report a case demonstrating the utility of positron emission tomography/computed tomography (PET/CT) combined with immunohistochemical examination for the accurate diagnosis and staging of HAC.

The extraintestinal pathogenic Escherichia coli (ExPEC) is a significant zoonotic bacterial pathogen that can cause severe infections and potentially cross-transmit between different hosts. The treatment of clinical bacterial infections is challenging because of the increasingly severe problem of drug resistance. The development of new strategies for managing bacterial infections is essential.

Aim: From 2015 to 2018, the 'Hospital-Acquired Pressure Injury (HAPI)' project was implemented in one local health district in Australia and utilised an implementation science approach to address rising pressure injury (PI) incidence and prevalence rates. This paper aims to examine whether the project was successful in sustaining low PI incidence and prevalence rates over the five-years following implementation (spanning the 2018/2019 to 2022/2023 financial years and the 2019-2023 calendar years).
Materials And Methods: A retrospective cohort study was conducted involving a comprehensive analysis of HAPI incidence, prevalence, and hospital-acquired complication (HAC) data spanning 5 years (incidence and HAC: 2018/2019 to 2022/2023 financial years; prevalence: January 2019 to December 2023 calendar years) post-implementation of the HAPI project.

Aneurysmal subarachnoid hemorrhage (aSAH) results in a complex systemic response that is critical to the pathophysiology of late complications and has important effects on outcomes. Omics techniques have expanded our investigational scope and depth into this phenomenon. In particular, metabolomics-the study of small molecules, such as blood products, carbohydrates, amino acids, and lipids-can provide a snapshot of dynamic subcellular processes and thus broaden our understanding of molecular-level pathologic changes that lead to the systemic response after aSAH.
