Abstract
Cerebral small vessel disease (CSVD) is a term used to describe abnormalities in the intracranial microvasculature affecting small arteries, arterioles, capillaries, and venules. The etiology of these conditions is not fully understood but inflammation appears to play a significant role. Periodontal diseases have been associated with conditions such as stroke and dementia, which are clinical consequences of CSVD. Periodontitis is a highly prevalent chronic multifactorial inflammatory disease regulated by the host immune response against pathogenic bacterial colonization around the teeth. The inflammatory response and the microbial dysbiosis produce pro-inflammatory cytokines that can reach the brain and promote local changes. This review will explore the potential association between periodontitis and CSVD by assessing the impact of periodontitis-induced inflammation and periodontopathogenic bacteria on the underlying mechanisms leading to CSVD. Given the association of periodontitis with stroke and dementia, which are clinical features of CSVD, it may be possible to suggest a link with CSVD. Current evidence linking periodontitis with neuroimaging findings of CSVD enforces the possible link between these conditions.

The Relationship between Dietary Habits and Periodontal Pathogens in a Sample of Romanian Children and Adolescents: A Cross-Sectional Study. CHILDREN (BASEL, SWITZERLAND) 2023; 10:1779. [PMID: 38002870 PMCID: PMC10670252 DOI: 10.3390/children10111779] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2023] [Revised: 10/29/2023] [Accepted: 11/01/2023] [Indexed: 11/26/2023]
Abstract
The role of diet in shaping oral microbiota and its potential contribution to the development of periodontal pathogens cannot be understated. This study aimed to explore the correlation between dietary habits and the prevalence of 11 periodontal pathogens among children and adolescents in Oradea, Romania. The identification of these pathogens was performed using the micro-IDent test kit, capable of detecting 11 specific periodontal pathogens. Bacterial sampling was conducted from the crevicular fluid in the morning, prior to brushing, followed by the completion of a brief questionnaire by parents. The questionnaire captured various aspects of the children's eating habits, including meal frequency, consumption of sweets, and hydration levels. The collected samples were dispatched to the laboratory for analysis, which provided insights into the abundance of microorganisms. The study encompassed 60 participants aged between 2 and 18 years, with the majority reported by their parents to have regulated meal timings, frequent sugar intake, and adequate hydration. The findings revealed significant associations between certain dietary factors and the presence of specific periodontal pathogens. Notably, the absence of breastfeeding was linked with the detection of Tannerella forsythia and Campylobacter rectus. Furthermore, frequent consumption of sweets corresponded with the presence of Capnocytophaga spp., which was particularly observed in individuals consuming sweets 2-3 times a day. Insufficient age-appropriate hydration showed an association with the prevalence of T. forsythia, Peptostreptococcus micros, and Capnocytophaga spp. In this sample, it became evident that eating habits and diet influenced the presence of several periodontal pathogens. The lack of breastfeeding was predominantly associated with positive results for T. forsythia and C. rectus, while inadequate hydration correlated more frequently with the presence of T. forsythia and P. micros. Moreover, frequent consumption of sweets was linked to the presence of Capnocytophaga spp.

Abstract
Pneumonia caused by Campylobacter rectus is very rare. Herein, we describe the treatment course and experiences of a patient with pneumonia caused by Campylobacter rectus. A 64-year-old woman with intermittent hemoptysis and part lung necrosis indicated by radiography was admitted to our hospital on March 15, 2021. After admission, a CT (Computer tomography)-guided percutaneous lung biopsy was identified as Campylobacter rectus positive by bacterial culture and metagenomic sequencing. The hemoptysis resolved, and the lesions in the right lower lung were gradually absorbed after treatment with anti-Campylobacter rectus drugs. In cases of pneumonia which unresolved by initial therapy and associated with more severe oral hygiene problems, the possibility of infection with oral pathogens (eg, Campylobacter rectus) should be considered. This case suggests that bacterial culture and metagenomic sequencing of the diseased tissue, particularly anaerobic culture, helps to clarify the etiological diagnosis.

Abstract
BACKGROUND Characteristics of airway microbiota might influence asthma status or asthma phenotype. Identifying the airway microbiome can help to investigate its role in the development of asthma phenotypes or small airway function. METHODS Bacterial microbiota profiles were analyzed in induced sputum from 31 asthma patients and 12 healthy individuals from Beijing, China. Associations between small airway function and airway microbiomes were examined. RESULTS Composition of sputum microbiota significantly changed with small airway function in asthma patients. Two microbiome-driven clusters were identified and characterized by small airway function and taxa that had linear relationship with small airway functions were identified. CONCLUSIONS Our findings confirm that airway microbiota was associated with small airway function in asthma patients.

Abstract
Introduction The critical challenge for periodontitis therapy is thoroughly eliminating the dental plaque biofilm, particularly penetrating the deep periodontal tissue. Regular therapeutic strategies are insufficient to penetrate the plaque without disturbing the commensal microflora of the oral cavity. Here, we constructed a Fe3O4 magnetic nanoparticle loading minocycline (FPM NPs) to penetrate the biofilm physically and effectively eliminate periodontal biofilm. Methods In order to penetrate and remove the biofilm effectively, Fe3O4 magnetic nanoparticles were modified with minocycline using a co-precipitation method. The particle size and dispersion of the nanoparticles were characterized by transmission electron microscopy, scanning electron microscopy, and dynamic light scattering. The antibacterial effects were examined to verify the magnetic targeting of FPM NPs. Confocal laser scanning microscopy was employed to check the effect of FPM + MF and develop the best FPM NPs treatment strategy. Additionally, the therapeutic effect of FPM NPs was investigated in periodontitis rat models. The expression of IL-1β, IL-6, and TNF-α in periodontal tissues was measured by qRT-PCR and Western blot. Results The multifunctional nanoparticles exhibited intense anti-biofilm activity and good biocompatibility. The magnetic forces could pull FMP NPs against the biofilm mass and kill bacteria deep in the biofilms both in vivo and in vitro. The integrity of the bacterial biofilm is disrupted under the motivation of the magnetic field, allowing for improved drug penetration and antibacterial performance. The periodontal inflammation recovered well after FPM NPs treatment in rat models. Furthermore, FPM NPs could be monitored in real-time and have magnetic targeting potentials. Conclusion FPM NPs exhibit good chemical stability and biocompatibility. The novel nanoparticle presents a new approach for treating periodontitis and provides experimental support for using magnetic-targeted nanoparticles in clinic applications.

Abstract
PURPOSE Survivors of stroke experience poor oral health during and following hospitalisation. Health professionals consistently report that oral hygiene is complex. Interventions aiming to improve the delivery of oral hygiene care by health professionals rarely use a theoretically driven approach. This study reports the first phase in an intervention development and uses the action, actor, context, target, time (AACTT) framework and theoretical domains framework (TDF) to understand who needs to do what differently in the delivery of oral hygiene care with hospitalised stroke survivors. METHOD Mixed methods including analysis of oral health policies and clinical guidelines using the AACTT framework, focus group discussions using the TDF and audit of 60 medical records. RESULTS Policies and guidelines lack specificity regarding what oral hygiene care is and who should be responsible. Health professionals have low beliefs in their capabilities and experience numerous contextual barriers. More than 40% of patients had no documented evidence of oral hygiene care. CONCLUSION This study used a theoretically driven approach to identify barriers and enablers to health professional delivery of oral hygiene care with stroke survivors. Interventions aiming to improve clinical practice should target beliefs about capabilities, improved access to resources and detailed oral hygiene clinical guidelines.Implications for rehabilitationSurvivors of stroke experience poor oral health which can contribute to further strokes, cardiovascular disease and mortality.Health care professionals report difficulties in delivering oral hygiene care to hospitalised stroke survivors and clinical guidelines lack detail regarding oral health assessments, interventions and training.Interventions aiming to improve the delivery of oral hygiene care should target health professional beliefs about their capabilities using strategies such as behavioural practice.Resources specific to oral hygiene care for more complex patients, including suctioning toothbrushes, should be readily accessible for health professional use.Clinical guidelines and policies on oral hygiene care should include detail about training content, assessments tools and how to adapt information for patients with complex impairments.

Abstract
OBJECTIVES There is accumulating evidence that periodontal disease is associated with atrial fibrillation (AF) or stroke, but it is unclear which causative species of periodontal disease are present in stroke patients with AF. We aimed to investigate the associations between AF and specific periodontal pathogens using serum titers of IgG antibodies of bacteria in acute stroke patients. MATERIALS AND METHODS Acute stroke patients were registered at two hospitals. Serum samples were evaluated for titers of antibodies against 9 periodontal pathogens (16 genotypes) using ELISAs. We identified AF in patients according to the following criteria: (1) a history of sustained or paroxysmal AF or (2) AF detection upon arrival or during admission. We carried out propensity score matching to categorize the patients as those with AF and those without. RESULTS Of the 664 acute stroke patients, 123 (18.5%) had AF. After propensity score matching, 234 patients were selected. Patients with AF had a higher prevalence of positive serum titers of antibodies against Porphyromonas gingivalis (FimA type III) and Porphyromonas gingivalis (FimA type V) than those without AF (59.0% vs. 39.3%, p=0.004 and 58.2% vs. 40.2%, p=0.009, respectively). CONCLUSIONS Porphyromonas gingivalis, especially FimA type III and type V, might be associated with AF in stroke patients.

Abstract
Antimicrobial surface modifications are required to prevent biomaterial-associated biofilm infections, which are also a major concern for oral implants. The aim of this study was to evaluate the influence of three different coatings on the biofilm formed by human saliva. Biofilms grown from human saliva on three different bioactive poly(oxanorbornene)-based polymer coatings (the protein-repellent PSB: poly(oxanorbornene)-based poly(sulfobetaine), the protein-repellent and antimicrobial PZI: poly(carboxyzwitterion), and the mildly antimicrobial and protein-adhesive SMAMP: synthetic mimics of antimicrobial peptides) were analyzed and compared with the microbial composition of saliva, biofilms grown on uncoated substrates, and biofilms grown in the presence of chlorhexidine digluconate. It was found that the polymer coatings significantly reduced the amount of adherent bacteria and strongly altered the microbial composition, as analyzed by 16S RNA sequencing. This may hold relevance for maintaining oral health and the outcome of oral implants due to the existing synergism between the host and the oral microbiome. Especially the reduction of some bacterial species that are associated with poor oral health such as Tannerella forsythia and Fusobacterium nucleatum (observed for PSB and SMAMP), and Prevotella denticola (observed for all coatings) may positively modulate the oral biofilm, including in situ.
