Finally, the findings could assist programs in library and information sciences in redesigning their curriculum and students who seek future careers in academic health sciences libraries
Revisiting Socransky’s Complexes: A Review Suggesting Updated New Bacterial Clusters (GF-MoR Complexes) for Periodontal and Peri-Implant Diseases and Conditions
No full textThis review aimed to identify newly discovered bacteria from individuals with periodontal/peri-implant diseases and organize them into new clusters (GF-MoR complexes) to update Socransky’s complexes (1998). For methodological development, the PCC (Population, Concept, Context) strategy was used for the focus question construction: “In patients with periodontal and/or peri-implant disease, what bacteria (microorganisms) were detected through laboratory assays?” The search strategy was applied to PubMed/MEDLINE, PubMed Central, and Embase. The search key terms, combined with Boolean markers, were (1) bacteria, (2) microbiome, (3) microorganisms, (4) biofilm, (5) niche, (6) native bacteria, (7) gingivitis), (8) periodontitis, (9) peri-implant mucositis, and (10) peri-implantitis. The search was restricted to the period 1998–2024 and the English language. The bacteria groups in the oral cavity obtained/found were retrieved and included in the GF-MoR complexes, which were based on the disease/condition, presenting six groups: (1) health, (2) gingivitis, (3) peri-implant mucositis, (4) periodontitis, (5) peri-implantitis, and (6) necrotizing and molar–incisor (M-O) pattern periodontitis. The percentual found per group refers to the number of times a specific bacterium was found to be associated with a particular disease. A total of 381 articles were found: 162 articles were eligible for full-text reading (k = 0.92). Of these articles, nine were excluded with justification, and 153 were included in this review (k = 0.98). Most of the studies reported results for the health condition, periodontitis, and peri-implantitis (3 out of 6 GF-MoR clusters), limiting the number of bacteria found in the other groups. Therefore, it became essential to understand that bacterial colonization is a dynamic process, and the bacteria present in one group could also be present in others, such as those observed with the bacteria found in all groups (Porphyromonas gingivalis, Tannarela forsythia, Treponema denticola, and Aggregatibacter actinomycetemcomitans) (GF-MoR’s red triangle). The second most observed bacteria were grouped in GF-MoR’s blue triangle: Porphyromonas spp., Prevotela spp., and Treponema spp., which were present in five of the six groups. The third most detected bacteria were clustered in the grey polygon (GF-MoR’s grey polygon): Fusobacterium nucleatum, Prevotella intermedia, Campylobacter rectus, and Eikenella corrodens. These three geometric shapes had the most relevant bacteria to periodontal and peri-implant diseases. Specifically, per group, GF-MoR’s health group had 58 species; GF-MoR’s gingivitis group presented 16 bacteria; GF-MoR’s peri-implant mucositis included 17 bacteria; GF-MoR’s periodontitis group had 101 different bacteria; GF-MoR’s peri-implantitis presented 61 bacteria; and the last group was a combination of necrotizing diseases and molar–incisor (M-I) pattern periodontitis, with seven bacteria. After observing the top seven bacteria of all groups, all of them were found to be gram-negative. Groups 4 and 5 (periodontitis and peri-implantitis) presented the same top seven bacteria. For the first time in the literature, GF-MoR’s complexes were presented, gathering bacteria data according to the condition found and including more bacteria than in Socransky’s complexes. Based on this understanding, this study could drive future research into treatment options for periodontal and peri-implant diseases, guiding future studies and collaborations to prevent and worsen systemic conditions. Moreover, it permits the debate about the evolution of bacterial clusters
The Impact of Technology Teaching in the Dental Predoctoral Curriculum on Students’ Perception of Digital Dentistry
No full textThe goal was to assess dental students’ perception of digital technologies after participating in a CAD/CAM exercise for scanning, designing, and manufacturing computer-aided provisional fixed dental restorations. A survey was conducted among second- (pre-D2 and post-D2), first- (D1, negative control), third-, and fourth-year dental students (D3 and D4, positive controls). Only OSU College of Dentistry students who completed the activity and completed the surveys were included. Seven questions were rated, which evaluated changes in knowledge, skill, interest, the importance of technology availability in an office, patients’ perception of technology, the importance of having the technology, and the expected frequency of clinics utilizing the technology. Statistical analysis was performed with a significance level of 0.05. A total of 74 pre-D2 and 77 post-D2 questionnaires were completed. Additionally, 63 D1, 43 D3, and 39 D4 participants responded to the survey. Significant differences were found for “knowledge” and “skill” between the pre-D2 and post-D2 and pre-D2 and control groups (p \u3c 0.001). There was a significant difference between the post-D2 participants and all the controls in terms of “interest” (p = 0.0127) and preference for in-practice technology availability (p \u3c 0.05). There were significant results between the post-D2 participants and all the controls regarding the importance of technology availability in an office (p \u3c 0.001) and the expected frequency of clinics utilizing the technology (p = 0.01). No significance was found for “value of technology to patients” and “the importance of having the technology”. The presence of technology in practice and in educational academic environments significantly improved students’ interest and perception of their knowledge and skill
Treatment strategies for vertical maxillary excess: Cases with and without anterior open bite
No full textThis comprehensive review investigates the treatment of vertical maxillary excess (VME) with and without anterior open bite (AOB) in seven unique case studies. These cases illustrate the implementation of advanced orthodontic techniques, such as miniscrew-assisted intrusion of the maxillary and mandibular arches. The multifaceted nature of AOB must be considered, highlighting the need for clear diagnostic criteria and an understanding of the long-term impacts of treatment strategies. The main goal of treatment is to reduce the vertical dimension of the maxillomandibular complex. A single miniscrew in the midpalatal region for the maxillary arch and two miniscrews in the buccal areas of the mandibular arch can be applied for the effective intrusion of the posterior teeth. The review then delves into the specific challenges and treatment modalities for managing VME without AOB, stressing the critical role of individualized intervention plans. Each case study demonstrates a different aspect of the treatment approach: from differential intrusion of molars to address esthetic concerns and functional issues to comprehensive strategies involving the intrusion of entire dental arches to correct severe malocclusions. The outcomes emphasize the importance of controlled orthodontic mechanics in achieving and maintaining optimal posttreatment stability. This review underscores the effectiveness of these treatment strategies in significantly improving facial profiles and dental function while highlighting the adjunctive use of myofunctional therapy and other retention techniques to prevent relapse. Collectively, these cases provide valuable insights into the tailored treatment of complex orthodontic conditions, offering guidance on achieving long-term success in clinical practice
Biomechanical and clinical considerations for the correction of Class II anterior open bite
No full textAnterior open bite (AOB) with mild-to-moderate skeletal discrepancies can be camouflaged by an orthodontic tooth movement. Conventional methods can improve occlusal relationships and some profile esthetics, but their mechanics may result in detrimental side effects such as a gummy smile, a high-frequency relapse, and an unfavorable facial profile. The emergence of temporary skeletal anchorage devices (TSADs) has facilitated the treatment of skeletal Class II AOB through intrusion of the posterior teeth and autorotation of the mandible, improving facial esthetics while minimizing the side effects. TSADs can also simplify treatment plans and offer a more predictable treatment result. Finite element studies have identified the location of the center of resistance of the dentition, providing a biomechanical basis for understanding 3-dimensional tooth movement patterns using TSADs. Therefore, biomechanical and clinical considerations are essential for correcting Class II AOB using TSADs
Vagotomy blunts cardiorespiratory responses to vagal afferent stimulation via pre- and postsynaptic effects in the nucleus tractus solitarii
No full textAbstract
Viscerosensory information travels to the brain via vagal afferents, where it is first integrated within the brainstem nucleus tractus solitarii (nTS), a critical contributor to cardiorespiratory function and site of neuroplasticity. We have shown that decreasing input to the nTS via unilateral vagus nerve transection (vagotomy) induces morphological changes in nTS glia and reduces sighs during hypoxia. The mechanisms behind post-vagotomy changes are not well understood. We hypothesized that chronic vagotomy alters cardiorespiratory responses to vagal afferent stimulation via blunted nTS neuronal activity. Male Sprague-Dawley rats (6 weeks old) underwent right cervical vagotomy caudal to the nodose ganglion, or sham surgery. After 1 week, rats were anaesthetized, ventilated and instrumented to measure mean arterial pressure (MAP), heart rate (HR), and splanchnic sympathetic and phrenic nerve activity (SSNA and PhrNA, respectively). Vagal afferent stimulation (2-50 Hz) decreased cardiorespiratory parameters and increased neuronal Ca2+ measured by in vivo photometry and in vitro slice imaging of nTS GCaMP8m. Vagotomy attenuated both these reflex and neuronal Ca2+ responses compared to shams. Vagotomy also reduced presynaptic Ca2+ responses to stimulation (Cal-520 imaging) in the nTS slice. The decrease in HR, SSNA and PhrNA due to nTS nanoinjection of exogenous glutamate also was tempered following vagotomy. This effect was not restored by blocking excitatory amino acid transporters. However, the blunted responses were mimicked by NMDA, not AMPA, nanoinjection and were associated with reduced NR1 subunits in the nTS. Altogether, these results demonstrate that vagotomy induces multiple changes within the nTS tripartite synapse that influence cardiorespiratory reflex responses to afferent stimulation. KEY POINTS: Multiple mechanisms within the nucleus tractus solitarii (nTS) contribute to functional changes following vagal nerve transection. Vagotomy results in reduced cardiorespiratory reflex responses to vagal afferent stimulation and nTS glutamate nanoinjection. Blunted responses occur via reduced presynaptic Ca2+ activation and attenuated NMDA receptor expression and function, leading to a reduction in nTS neuronal activation. These results provide insight into the control of autonomic and respiratory function, as well as the plasticity that can occur in response to nerve damage and cardiorespiratory disease
What Competencies Matter Most to Improve Hospitals’ Performance in the Value-Based Purchasing Environment?
No full textAbstract The Hospital Value-based Purchasing program is a financial incentive program for U.S. acute-care hospitals. Its unique challenges call for hospital executives to possess unique leadership competencies. In this national, cross-sectional qualitative study, primary demographic, and textual data were collected using a self-developed survey instrument and analyzed using Minitab and MAXQDA. Final sample size was n = 190. Three major findings emerged. First, executive leadership competencies were perceived to impact U.S. acute-care hospitals’ Value-based Purchasing (HVBP) organizational performance. Second, the top five executive leadership competencies that mattered most to these HVBP organizational performance were: organizational awareness, collaboration, team leadership, human resource management, and information and technology management. Finally, U.S. acute-care hospitals’ executive leaders recognized managing the HVBP program’s specific challenges and thus urged to provide executive leadership competency development programs
Histological Assessment of Bone Regeneration in the Maxilla with Homologous Bone Graft: A Feasible Option for Maxillary Bone Reconstruction
No full textBone biomaterials have been increasingly used to reconstruct maxillary atrophic ridges. Thus, the aim of this study was to evaluate bone reconstruction in the maxilla using a homologous cortico-cancellous FFB (lyophilized) graft and verify its reliability. Eight individuals were included from 2014 to 2018. The first surgery was performed to install homologous bone blocks in the maxilla. The period of the second intervention varied between 5 months and 15 days to 11 months (≈7.93 months). The biopsies were taken from the central region of the matured graft during the surgery for implant placement. All patients presented clinical and radiographic conditions for the installation of dental implants. There was a 100% of survival rate. The histological assessment showed that the homologous block bone graft was an osteoconductive biomaterial, with connective tissue present, and newly formed bone juxtaposed on its surface. There were bone trabeculae with osteocytes and active osteoblasts with connective tissue in the mineralization process; the remodeling process can be found through the reverse lines. A limited focus of necrosis with fibrosis was detected, with small resorption and areas of inflammatory infiltrate, but without clinical significance. The homologous block bone graft can be considered a feasible option to substitute the autogenous bone graft (gold standard), with predictable clinical and favorable histological results. The patients had a shorter surgical period, low morbidity, and an unlimited amount of biomaterial available at an accessible cost
An update on migraine: Current and new treatment options
No full textAbstract
Migraine headache is a common and potentially debilitating disorder often treated by physician associates/assistants (PAs) and other providers. With the recent advances in new drugs and device technology for the treatment of migraine, the American Headache Society has released a consensus statement on both preventive and acute strategies for clinical practice. The US FDA has recently approved various types of medications and devices for the treatment and prevention of migraine attacks including several calcitonin gene-related peptide (CGRP) receptor inhibitors, a selective serotonin receptor agonist (SSRA), noninvasive vagus nerve stimulation (nVNS), external trigeminal nerve stimulation (e-TNS), and external concurrent occipital and trigeminal neurostimulation (eCOT-NS), among other pharmacologic and nonpharmacologic options. This article provides a review of migraine prevention and acute treatment protocol, highlighting new approaches to both
