Saudi Med J 2024; 45:724-730. [PMID: 38955441 PMCID: PMC11237278 DOI: 10.15537/smj.2024.45.7.20240294] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/12/2024] [Accepted: 05/27/2024] [Indexed: 07/04/2024] Open
Abstract
OBJECTIVES To evaluated the home healthcare efficacy in managing tracheostomy patients at King Abdulaziz Medical City under the Ministry of National Guard Health Affairs. Home healthcare is care provided to patients in the convenience of their homes to ensure high-quality care based on healthcare providers' supervision. METHODS This retrospective cohort study utilizing a non-probability consecutive sampling technique, including all available tracheal patients with no exclusion criteria, was carried out in Riyadh, Saudi Arabia, between January 2019 and June 2022. The collected data included patient demographic variables and respiratory settings (ventilation type, daily ventilation need, tracheostomy duration, and ventilator settings). The outcomes included mortality rate and therapeutic outcomes of tracheal management. RESULTS Of the 183 patients in the study, the most common type of respiratory-related infection was pneumonia (53%). Unlike respiratory-related causes, The mortality rate of patients admitted to the intensive care unit that was unrelated to respiratory causes was statistically significant (57%) (p=0.003). The mortality rate of patients who used aerosol tracheal collars (34%) was markedly higher than mechanically ventilated patients (57%) (p=0.004). The mortality rate following discharge from HHC was 40%, and was higher among patients aged >70 years (47%) (p=0.04). CONCLUSION Pneumonia was associated with the majority of ventilator-related infections and resulted in hospital readmissions. Ensuring proper practices and caregiver education is crucial to decrease the incidence of ventilator-related infections.

Abstract
BACKGROUND The focal infection theory has been used to explain several chronic systemic diseases in the past. Systemic diseases were thought to be caused by focal infections, such as caries and periodontal diseases, and dentists were held responsible for these diseases due to the spread of oral infections. As knowledge of the interrelationship between oral microorganisms and the host immune response has evolved over the last few decades, the focal infection theory has been modified in various ways. The relationship between oral and systemic health appears to be more complex than that suggested by the classical theory of focal infections. Indeed, the contribution of the oral microbiota to some systemic diseases is gaining acceptance, as there are strong associations between periodontal disease and atherosclerotic vascular disease, diabetes, and hospital-associated pneumonia, amongst others. As many jurisdictions have various protocols for managing this oral-systemic axis of disease, we sought to provide a consensus on this notion with the help of a multidisciplinary team from the Czech Republic. METHODS A multidisciplinary team comprising physicians/surgeons in the specialities of dentistry, ear-nose and throat (ENT), cardiology, orthopaedics, oncology, and diabetology were quetioned with regard to their conceptual understanding of the focal infection theory particularly in relation to the oral-systemic axis. The team also established a protocol to determine the strength of these associations and to plan the therapeutic steps needed to treat focal odontogenic infections whenever possible. RESULTS Scoring algorithms were devised for odontogenic inflammatory diseases and systemic risks, and standardised procedures were developed for general use. CONCLUSIONS The designed algorithm of the oral-systemic axis will be helpful for all health care workers in guiding their patient management protocol.

Abstract
Aspiration pneumonia (AP), inflammation of the lung parenchyma initiated by aspirated microorganisms into the lower airways from proximal sites, including the oral cavity, is prevalent in, and problematic for, the elderly, especially those in institutions, and for those with several important risk factors. Many factors influence the pathogenesis of AP, including dysphagia, poor oral hygiene, diminished host defense, and underlying medical conditions. This article reviews the epidemiology, microbiology, pathogenesis, and prevention of AP, focusing on the role of poor oral health as a risk factor for, and on dental care for the prevention and management of, this important infection.

Abstract
Periodontitis is a microbially driven, host-mediated disease that leads to loss of periodontal attachment and resorption of bone. It is associated with the elevation of systemic inflammatory markers and with the presence of systemic comorbidities. Coronavirus disease 2019 (COVID-19) is a contagious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Although the majority of patients have mild symptoms, others experience important complications that can lead to death. After the spread of the COVID-19 pandemic, several investigations demonstrating the possible relationship between periodontitis and COVID-19 have been reported. In addition, both periodontal disease and COVID-19 seem to provoke and/or impair several cardiometabolic complications such as cardiovascular disease, type 2 diabetes, metabolic syndrome, dyslipidemia, insulin resistance, obesity, non-alcoholic fatty liver disease, and neurological and neuropsychiatric complications. Therefore, due to the increasing number of investigations focusing on the periodontitis-COVID-19 relationship and considering the severe complications that such an association might cause, this review aims to summarize all existing emerging evidence regarding the link between the periodontitis-COVID-19 axis and consequent cardiometabolic impairments.

Functionalized Self-Assembled Monolayers: Versatile Strategies to Combat Bacterial Biofilm Formation. Pharmaceutics 2022; 14:pharmaceutics14081613.

Abstract
Bacterial infections due to biofilms account for up to 80% of bacterial infections in humans. With the increased use of antibiotic treatments, indwelling medical devices, disinfectants, and longer hospital stays, antibiotic resistant infections are sharply increasing. Annual deaths are predicted to outpace cancer and diabetes combined by 2050. In the past two decades, both chemical and physical strategies have arisen to combat biofilm formation on surfaces. One such promising chemical strategy is the formation of a self-assembled monolayer (SAM), due to its small layer thickness, strong covalent bonds, typically facile synthesis, and versatility. With the goal of combating biofilm formation, the SAM could be used to tether an antibacterial agent such as a small-molecule antibiotic, nanoparticle, peptide, or polymer to the surface, and limit the agent’s release into its environment. This review focuses on the use of SAMs to inhibit biofilm formation, both on their own and by covalent grafting of a biocidal agent, with the potential to be used in indwelling medical devices. We conclude with our perspectives on ongoing challenges and future directions for this field.

Abstract
OBJECTIVE Postoperative pneumonia is among the most common complications in elderly patients after hip fracture surgery. We implemented a proactive postoperative pneumonia prevention protocol and analyzed the incidence of postoperative pneumonia in elderly patients (≥70 years of age) receiving this protocol after hip fracture surgery versus those receiving usual care before the protocol's implementation at our institution. MATERIALS AND METHODS From November 2018 to October 2019, the proactive postoperative pneumonia prevention protocol was implemented. The treatment included intensified physical therapy, postoperative pulmonary exercises and oral care, in addition to the usual surgical treatment for elderly patients with hip fracture. The intervention cohort data were compared with a historical control cohort treated from July 2017 to June 2018. The primary outcome of this study was the incidence of postoperative pneumonia in both groups, diagnosed according to the presence of two of three of the following: elevated infection parameters, radiologic examination confirmation of pneumonia of the chest or clinical suspicion. RESULTS A total of 494 patients (n= 249 in the historical control cohort and n=245 in the intervention cohort) were included. A total of 69 patients developed postoperative pneumonia. The incidence of postoperative pneumonia was significantly lower (6.7 percentage points) in the group receiving the proactive postoperative pneumonia prevention protocol (17.3% in the historical control cohort vs 10.6% in the intervention cohort; p=0.033). DISCUSSION AND CONCLUSION A proactive postoperative pneumonia prevention protocol showed promise in decreasing the occurrence of postoperative pneumonia after hip fracture surgery in elderly patients.

Abstract
Nonventilator hospital-associated pneumonia has recently emerged as an important preventable hospital-associated infection, and is a leading cause of healthcare-associated infection. Substantial accumulated evidence links poor oral health with an increased risk of pneumonia, which can be caused by bacterial, viral, or fungal pathogens, each with their own distinct mechanisms of transmission and host susceptibility. These infections are frequently polymicrobial, and often include microbes from biofilms in the oral cavity. Evidence documenting the importance of oral care to prevent nonventilator hospital-associated pneumonia is continuing to emerge. Reduction of oral biofilm in these populations will reduce the numbers of potential respiratory pathogens in the oral secretions that can be aspirated, which in turn can reduce the risk for pneumonia. This review summarizes up-to-date information on the role of oral care in the prevention of nonventilator hospital-associated pneumonia.

Abstract
The aim of this study was to draw attention to the possible consequences of improper, unhygienic use of mouth and nose covers in the context of prophylaxis against the spread of COVID-19 from the point of view of a family physician and focus on the risk of respiratory infections and skin lesions in patients, in different age groups. The use of protective masks may reduce the likelihood of infection but will not eliminate the risk of infection. However, it should be remembered that any mask, no matter how effective the filtration is or how well it seals, will have little effect if not used in conjunction with other preventive measures, including isolation of infected people, immunization, proper respiratory culture, regular, frequent replacement of masks, and hand hygiene. Additionally, certain risks associated with this form of prophylaxis should be taken into account, which, unfortunately, may also aggravate or even constitute a source of serious respiratory infections and lead to the development and aggravation of skin problems. Moreover, educating society not only on hand hygiene but also on the topic of the value of nose and mouth covers, as well as the frequency of their replacement and/or disinfection, is becoming a significant issue.

Abstract
Periodontal diseases are a range of polymicrobial infectious disorders, such as gingivitis and periodontitis, which affect tooth-supporting tissues and are linked to playing a role in the exacerbation of several pulmonary diseases. Pulmonary diseases, such as pneumonia, chronic obstructive pulmonary disease (COPD), asthma, tuberculosis, COVID-19, and bronchiectasis, significantly contribute to poor quality of life and mortality. The association between periodontal disease and pulmonary outcomes is an important topic and requires further attention. Numerous resident microorganisms coexist in the oral cavity and lungs. However, changes in the normal microflora due to oral disease, old age, lifestyle habits, or dental intervention may contribute to altered aspiration of oral periodontopathic bacteria into the lungs and changing inflammatory responses. Equally, periodontal diseases are associated with the longitudinal decline in spirometry lung volume. Several studies suggest a possible beneficial effect of periodontal therapy in improving lung function with a decreased frequency of exacerbations and reduced risk of adverse respiratory events and morbidity. Here, we review the current literature outlining the link between the oral cavity and pulmonary outcomes and focus on the microflora of the oral cavity, environmental and genetic factors, and preexisting conditions that can impact oral and pulmonary outcomes.

Abstract
Cystic fibrosis is an inherited disease that affects multiple organs and systems. The oral cavity can serve as a substantial source of bacteria, causing respiratory infections and diseases which continue to dictate the clinical course of the disease and prognosis in patients with CF. Low voltage and electric current could effectively kill bacteria and biofilms, and the activity of milliampere currents could be used as an effective method of fighting bacteria. This study evaluated the effect of low amperage electric current on the formation of Staphylococcus aureus biofilms on dental implants such as titanium and zirconium in patients with cystic fibrosis. Our studies suggest that a constant electric current at a low intensity of 1 mA and 10 mA is inhibiting bacterial adhesion, detaching biofilm-forming bacteria on biomaterials used in dental implants such as titanium and zirconium, and destroying bacterial cells of Staphylococcus aureus strains. In addition, we observed the selection of an appropriate biomaterial for implants in people affected by chronic diseases, such as CF, should be carefully planned.

Abstract
In the last five decades, considerable progress has been made towards understanding the etiology and pathogenesis of periodontal diseases and their interactions with the host. The impact of an individual periodontal condition on systemic homeostasis became more evident because of this knowledge and prompted advances in studies that associate periodontitis with systemic diseases and conditions. The term Periodontal Medicine describes how periodontal infection/inflammation can affect extraoral health. This review presents the current scientific evidence on the most investigated associations between periodontitis and systemic diseases and conditions, such as cardiovascular diseases, diabetes, preterm birth and low birth weight, and pneumonia. Additionally, other associations between periodontitis and chronic inflammatory bowel disease, colorectal cancer, and Alzheimer's disease that were recently published and are still poorly studied were described. Thus, the aim of this review was to answer the following question: What is the future of Periodontal Medicine? Epidemiological evidence and the evidence of biological plausibility between periodontitis and general health reinforce the rationale that the study of Periodontal Medicine should continue to advance, along with improvements in the epidemiological method, highlighting the statistical power of the studies, the method for data analysis, the case definition of periodontitis, and the type of periodontal therapy to be applied in intervention studies.

Abstract
Acute pneumonia is an inflammatory disease caused by several pathogens, with symptoms such as fever and chest pain, to which children are particularly vulnerable. Gancaonin N is a prenylated isoflavone of Glycyrrhiza uralensis that has been used in the treatment of various diseases in oriental medicine. There are little data on the anti-inflammatory efficacy of Gancaonin N, and its effects and mechanisms on acute pneumonia are unknown. Therefore, this study was conducted as a preliminary analysis of the anti-inflammatory effect of Gancaonin N in lipopolysaccharide (LPS)-induced RAW264.7 cells, and to identify its preventive effect on the lung inflammatory response and the molecular mechanisms underlying it. In this study, Gancaonin N inhibited the production of NO and PGE2 in LPS-induced RAW264.7 cells and significantly reduced the expression of iNOS and COX-2 proteins at non-cytotoxic concentrations. In addition, in LPS-induced A549 cells, Gancaonin N significantly reduced the expression of COX-2 and pro-inflammatory cytokines, such as TNF-α, IL-1β, and IL-6. Moreover, Gancaonin N reduced MAPK signaling pathway phosphorylation and NF-κB nuclear translocation. Therefore, Gancaonin N relieved the inflammatory response by inactivating the MAPK and NF-κB signaling pathways; thus, it is a potential natural anti-inflammatory agent that can be used in the treatment of acute pneumonia.

Abstract
Hospitalized older adults frequently develop aspiration pneumonia, swallowing dys-function (dysphagia), and sarcopenia. In the current study, we propose a framework that incorporates these three factors into a vicious circle that leads to deconditioning, a condition frequently experienced by this vulnerable population. Viewing aspiration pneumonia, dysphagia, and sarcopenia, along with their interrelationships through the lens of this vicious circle, illuminates the critical role that oral health plays in deconditioning. Moreover, this framework highlights oral care as a key nursing intervention for reducing deconditioning in hospitalized older adults. Supporting this view, several studies have shown that oral care can improve health outcomes for hospitalized older adults. However, despite oral care being an essential nursing intervention that restores oral function and promotes patient wellness, it is one of the most neglected nursing interventions. Missed oral care occurs due to staff's limited awareness of its significance for care-dependent older adults in hospital settings. We hope that this vicious circle paradigm helps raise awareness of the significance of oral care to prevent deconditioning in hospitalized older adults.

Abstract
Aspiration pneumonia (AP), inflammation of the lung parenchyma initiated by aspirated microorganisms into the lower airways from proximal sites, including the oral cavity, is prevalent in, and problematic for, the elderly, especially those in institutions, and for those with several important risk factors. Many factors influence the pathogenesis of AP, including dysphagia, poor oral hygiene, diminished host defense, and underlying medical conditions. This article reviews the epidemiology, microbiology, pathogenesis, and prevention of AP, focusing on the role of poor oral health as a risk factor for, and on dental care for the prevention and management of, this important infection.

Abstract
Background Healthcare-acquired pneumonias are a significant risk for nursing home and hospital patients. While oral care interventions (OCIs) have been found to be effective in reducing the risk of ventilator-associated pneumonia (VAP), their utility in mitigating non-ventilator-associated pneumonias (NVAP) remains unknown. We performed a structured meta-analysis of randomised and non-randomised clinical trials of enhanced oral hygiene procedures on NVAP.Methods We searched PubMed and Embase to include clinical trials (randomised and non-randomised), and observational (retrospective and prospective) and quasi-experimental studies examining the effect of any method of OCI on incidence of NVAP.Results After quality assessment and consensus agreement between authors, we synthesised six randomised clinical trials (3,891 patients), two non-randomised trials (2,993 patients), and separately assessed a retrospective trial (143 patients) and a quasi-experimental study (83 patients). Most studies, performed in nursing homes, did not show a significant association between OCI and NVAP prevention (RR random 0.89, 95% CI 0.64-1.25, p value 0.50). Likewise, the non-randomised trials failed to show an association between NVAP risk and OCI (RR random 1.42, 95% CI, 0.70-2.88, p value 0.32). However, in the subgroup analysis comparing dental professional involvement in care vs usual care, reduced NVAP risk was demonstrated (RR random 0.65, 95% CI 0.43-0.98, p value 0.03).Conclusions Study results suggest that professional dental care may confer some benefit among NVAP patients. The lack of consistent OCI protocols, data in hospitalised patients and robust randomised clinical trials do not allow definitive conclusions about the contribution of OCI in mitigating NVAP risk.

Abstract
In the last decades, resistant microbial infection rate has dramatically increased, especially infections due to biofilm-producing strains that require increasingly complex treatments and are responsible for the increased mortality percentages compared with other infectious diseases. Considering that biofilms represent a key factor for a wide range of chronic infections with high drug tolerance, the treatment of biofilm-causing bacterial infections represents a great challenge for the future. Among new alternative strategies to conventional antimicrobial agents, the scientific interest has shifted to the study of biologically active compounds from plant-related extracts with known antimicrobial properties, in order to also evaluate their antibiofilm activity. In this regard, the aim of this study has been to assess the antibiofilm activity of polyphenolic extracts from myrtle leaf and pomegranate peel against oral pathogens of dental plaque, an excellent polymicrobial biofilm model. In particular, the in vitro antibiofilm properties of myrtle and pomegranate extracts, also in binary combination, were highlighted. In addition to inhibiting the biofilm formation, the tested polyphenolic extracts have been proven to destroy both preformed single-species and multispecies biofilms formed by Streptococcus mutans, Streptococcus oralis, Streptococcus mitis, and Rothia dentocariosa oral isolates, suggesting that the new natural sources are rich in promising compounds able to counteract biofilm-related infections.

Abstract
This study aimed to map evidence-based guidelines for oral care of the dependent elders and perform the cross-cultural adaptation to Brazilian Portuguese. Initially, a systematized review was conducted in Medline, Scielo, Scopus, Web of Science, and Google Scholar databases without restrictions in search period or type of study. Articles in English, Spanish, and Brazilian Portuguese describing evidence-based guidelines for oral care, including oral hygiene recommendations, of institutionalized dependent elders were included as long as they presented an evaluation of evident quality. The guideline that met inclusion criteria was submitted to cross-cultural adaptation after obtaining permission from the original authors. Two hundred and nineteen references were found. Three selected articles described evidence-based guidelines for oral care, but the Oral Health Care Guideline for Older People in Long-term Care Institutions (OGOLI), originally developed and implemented in the Netherlands, was selected. It was based on evidence level A2 and consensus of experts and met the quality requirements of the Appraisal of Guidelines for Research & Evaluation (AGREE). This guideline presents oral care recommendations for elders with different levels of dependence in activities of daily living to be performed by caregivers and nursing staff. The adaptation of the OGOLI was mainly on the attributions of care providers, given the differences in professional regulations between Brazil and the Netherlands. The cross-cultural equivalence between OGOLI and its Brazilian Portuguese version was verified.

Abstract
There are countless efficacious interventions that improve outcomes when conducted in controlled situations. Many fewer are effective when implemented in real-world situations, largely because they are not implemented with fidelity. Still fewer are sustained over time, for reasons including lack of institutional support and fit with existing values, among others. It is especially important to examine fidelity and sustainability when efficacious interventions are being implemented, because these interventions are the ones that hold the most promise. This project examined the fidelity and sustainability of Mouth Care Without a Battle (MCWB), an evidence-based program conducted in a two-year cluster randomized trial in 14 nursing homes. Results that triangulated two sources of data indicated that fidelity decreased after the first year; they provide guidance to promote fidelity and sustainability of this and other new care practices in nursing homes, including ongoing education, coaching, evaluation, feedback, and sufficient resources.

Abstract
Ventilator-associated pneumonia (VAP) is a highly common hospital-acquired infection affecting people that require mechanical ventilation. The endotracheal tube (ETT) used during the ventilation process provides a surface that can allow bacterial colonization and biofilm formation, which can lead to VAP. Although various approaches, including ETT design and material selection, as well as antimicrobial coatings have been employed to minimize adverse events, VAP remains a significant unresolved clinical issue. In this study, we have utilized a novel styrylbenzene-based antimicrobial (BCP3) in a simple and robust coating that allows its long-term release at an effective level. BCP3 was applied onto PVC ETT segments blended together with poly(lactic-co-glycolic acid) via a facile dip-coating process with controlled loadings. In vitro studies demonstrated concentration-dependent release of BCP3 from the coatings for at least 31 days. Bacterial assays using major VAP culprits, Staphylococcus aureus and Pseudomonas aeruginosa, demonstrated significant growth inhibition, with a stronger effect on S. aureus. Despite its ability to inhibit bacterial growth, BCP3 showed no cytotoxicity toward mammalian (L929) fibroblasts, which makes it attractive from a clinical perspective. The coating procedure was successfully translated to coat the entire ETTs, making it highly amenable for large-scale manufacturing.

Abstract
BACKGROUND Staphylococcus aureus have a great ability to become rapidly resistant to conventional antimicrobial therapies. This study evaluated the efficacy of antimicrobial photodynamic therapy (aPDT) mediated by Curcumin (Cur) and light-emitting diode (LED) in the inactivation of biofilms of methicillin susceptible and resistant S. aureus (MSSA and MRSA, respectively). METHODS Biofilms were treated with Cur (20, 40 or 80 μM) and illuminated with LED source (455 ± 3 nm; 5.28 J/cm2) (aPDT groups), or treated either with Cur or LED only. Other samples were not exposed to Cur or LED (negative control). The biofilms viability after all experimental conditions were evaluated by counting the number of colonies (CFU/mL) and XTT assay. Additional samples were also evaluated by LIVE/DEAD® staining using confocal laser scanning microscopy (CLSM). Data were analyzed by ANOVAs followed by the Games-Howell post hoc test (α = 0.05). RESULTS For both strains, all aPDT groups significantly reduced both CFU/mL and metabolic activity of biofilms compared to the negative control (p < 0.001). The results were enhanced when 80 μM of Cur was used. CLSM images showed that both bacteria biofilms submitted to aPDT had a large number of red-stained colonies, especially at aPDT80. In general, MRSA biofilms tended to be less susceptible to aPDT than MSSA biofilms. CONCLUSIONS It can be concluded that aPDT mediated by Cur and LED was an efficient method to inactivate 48 -h biofilms of both S. aureus strains.

Abstract
Human oral cavity is a complex habitat comprising about 700 microbial species and represents the most complex microbiota after gastrointestinal tract. In fact, oral microbiota directly influences health, metabolism and immune responses of the host. Metagenomic studies based on 16S rDNA profiling has reported the inhabitant bacteria mainly belonging to phyla Firmicutes, Proteobacteria, Actinobacteria, Fusobacteria, Spirochaetes and Bacteroidetes. Therefore, it is essential to isolate these strains and characterize in detail to understand their interaction. We have isolated strains from subgingival plaque from healthy to diseased individuals and the molecular characterization based on 16S rRNA gene sequence analysis showed predominance of Firmicutes, specifically members of the genus Streptococcus. Species of Lactobacillus and Veillonella were also found in significant number, which are considered as secondary colonizers. However, the population of Lactobacillus was decreased in diseased conditions with the increase in opportunistic pathogenic strains pertaining to genera like Campylobacter, Neisseria, Enterobacter, Pseudomonas and Morococcus. Further, we have also made an attempt to gain genomic insights on adaptation features and interactions of an isolate, Lactobacillus sp. strain DISK7 by performing whole genome sequencing and analysis, subsequently biochemical characterization to explore its functional and metabolic properties for the development as probiotic agent.

Abstract
Rationale: Mechanisms of HIV-associated chronic obstructive pulmonary disease (COPD) are poorly understood. The oral microbiome shapes the lung microbiome, and gut dysbiosis can affect lung diseases; however, relationships of the oral and gut microbiome to COPD in HIV have not been explored.Objectives: To examine alterations in the oral and gut microbiome associated with pulmonary disease in persons with HIV (PWH).Methods: Seventy-five PWH and 93 HIV-uninfected men from the MACS (Multicenter AIDS Cohort Study) performed pulmonary function testing. Sequencing of bacterial 16S ribosomal RNA in saliva and stool was performed. We used nonmetric multidimensional scaling, permutational multivariate ANOVA, and linear discriminant analysis to analyze communities by HIV and lung function.Measurements and Main Results: Oral microbiome composition differed by HIV and smoking status. Alterations of oral microbial communities were observed in PWH with abnormal lung function with increases in relative abundance of Veillonella, Streptococcus, and Lactobacillus. There were no significant associations between the oral microbiome and lung function in HIV-uninfected individuals. No associations with HIV status or lung function were seen with the gut microbiome.Conclusions: Alterations of oral microbiota in PWH were related to impaired pulmonary function and to systemic inflammation. These results suggest that the oral microbiome may serve as a biomarker of lung function in HIV and that its disruption may contribute to COPD pathogenesis.

Oral Care Clinical Trial to Reduce Non-Intensive Care Unit, Hospital-Acquired Pneumonia: Lessons for Future Research. J Healthc Qual 2020; 41:1-9.

Abstract
Hospital-acquired pneumonia (HAP) contributes greatly to patient mortality and healthcare costs. Studies have shown that aggressive oral care in intensive care units (ICUs) can significantly reduce pneumonia rates, and hospitals have implemented stringent protocols in this setting. However, little is known about the effectiveness of aggressive oral care in reducing HAP in non-intensive care wards, prompting us to conduct a nonrandomized controlled clinical trial. A structured toothbrushing program was provided to an experimental cohort of patients. A control group received usual care. Patient demographics, toothbrushing frequency, and pneumonia diagnosis were recorded over a 3.5-month period. Difference in pneumonia rates was computed using unadjusted and multivariate logistic regression analyses. No significant difference in pneumonia rates between control and experimental groups was found (1.7% versus 1.8%). Toothbrushing rates increased significantly in the experimental group (p = .002) but fell short of protocol frequency. It became apparent that aggressive toothbrushing program implementation requires nursing-led interdisciplinary involvement, more intensive training, a streamlined documentation system, and efficient compliance tracking. Lessons from this study should be used for future large-scale research. A secondary analysis of these data did, however, suggests that increasing toothbrushing rates may have the potential to reduce pneumonia in the non-ICU acute care setting.

The Association of Periodontal Treatment and Decreased Pneumonia: A Nationwide Population-Based Cohort Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17010356. [PMID: 31948027 PMCID: PMC6982322 DOI: 10.3390/ijerph17010356] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 12/01/2019] [Revised: 12/25/2019] [Accepted: 01/02/2020] [Indexed: 12/21/2022]
Abstract
Pneumonia is a common respiratory infectious disease that involves the inflammation of the pulmonary parenchyma. Periodontal disease is widespread and correlated with pneumonia. However, the relationship between periodontal treatment and clinical infectious outcomes in patients with pneumonia has remained undetermined. The aim of this study was to investigate the association between periodontal treatment and the risk of pneumonia events in the Taiwanese population. A nationwide population-based cohort study was conducted using data from the Taiwanese National Health Insurance Research Database (NHIRD). A total of 49,400 chronic periodontitis patients who received periodontal treatment from 2001 to 2012 were selected. In addition, 49,400 healthy individuals without periodontal diseases were picked randomly from the general population after propensity score matching according to age, gender, monthly income, urbanization, and comorbidities. The Cox proportional hazard regression analysis was adopted to assess the hazard ratio (HR) of pneumonia between the periodontal treatment cohort and the comparison cohort. The average ages of the periodontal treatment and comparison groups were 44.25 ± 14.82 years and 44.15 ± 14.5 years, respectively. The follow up durations were 7.66 and 7.41 years for the periodontal treatment and comparison groups, respectively. We found 2504 and 1922 patients with newly diagnosed pneumonia in the comparison cohort and the periodontal treatment cohort, respectively. The Kaplan–Meier plot revealed that the cumulative incidence of pneumonia was significantly lower over the 12 year follow-up period in the periodontal treatment group (using the log-rank test, p < 0.001). In conclusion, this nationwide population-based study indicated that the patients with periodontal treatment exhibited a significantly lower risk of pneumonia than the general population.

Abstract
OBJECTIVE To conduct a systematic review and meta-analysis to evaluate the recent scientific literature addressing the association between periodontitis and asthma, chronic obstructive pulmonary disease (COPD), and pneumonia. MATERIALS AND METHODS The search for studies was carried out using MEDLINE/PubMed, EMBASE, Lilacs, Web of Science, Scopus, and SciELO databases, including the gray literature (ProQuest). Reference lists of selected articles were also searched. Studies having varying epidemiological designs assessing the association between periodontitis and respiratory diseases in human subjects were eligible for inclusion. Three independent reviewers performed the selection of articles and data extraction. Fixed and random effects meta-analysis were performed for the calculation of the association measurements (Odds Ratio-OR) and 95% confidence intervals (95% CI). RESULTS A total of 3,234 records were identified in the database search, with only 13 studies meeting the eligibility criteria and 10 studies contributed data for meta-analysis. Using a random effects models periodontitis was associated with asthma: ORadjusted: 3.54 (95% CI: 2.47-5.07), I2 = 0%; with COPD: OR adjusted: 1.78 (95% CI: 1.04-3.05), I2 = 37.9%; and with pneumonia: OR adjusted: 3.21 (95% CI: 1.997-5.17), I2 = 0%. CONCLUSIONS The main findings of this systematic review validated an association between periodontitis and asthma, COPD and pneumonia.

Abstract
This study aims to evaluate the in vitro antimicrobial and immunomodulatory activities and cytotoxicity of chlorhexidine (CHX) and synoeca-MP peptide alone or in combination against Pseudomonas aeruginosa. The antimicrobial property was evaluated by the determination of minimal inhibitory concentration, minimum bactericidal concentration, and planktonic bacteria and biofilm inhibition. Immunomodulatory activity was determined by enzyme-linked immunosorbent assay and nitric oxide production by the Griess reaction method. According to the results, synoeca-MP combined with CHX demonstrated antimicrobial effectiveness compared with its isolated use, in addition to immunomodulatory activity (upregulating MPC-1 and tumor necrosis factor-α and downregulating nitric oxide and interleukin-10). In this context, it is expected that the substances, together, could be capable of controlling bacterial infection and dissemination, besides potentiating macrophages' immune response against the studied microorganism. Moreover, reducing the CHX concentration by the addition of synoeca-MP peptide may, in a beneficial way, minimize the undesirable effects of both, CHX and synoeca-MP in a clinical setting.

Abstract
OBJECTIVES The aims of this article are to identify all the published systematic reviews (SRs) and meta-analyses (MAs) that studied the relationship between periodontal and systemic diseases and to assess their quality using 2 scales (the Overview Quality Assessment Questionnaire [OQAQ] and A Measurement Tool to Assess Systematic Reviews [AMSTAR] checklist). METHODS For SRs and MAs to be included, they should have investigated one of the following systemic diseases: pulmonary conditions, cardiac conditions, endocrine conditions, cancer, blood disorders, psychological conditions, anxiety, depression, mood disorders, and several other diseases. Two investigators screened MEDLINE via PubMed, Embase, Scopus, Web of Science, and the Cochrane Database of Systematic Reviews. The tools used to evaluate quality were the AMSTAR scale and OQAQ. The protocol was prospectively registered in PROSPERO (CRD42018102208). RESULTS The search strategy found 691 unique articles, 42 of which met the eligibility criteria and were included in this review. Diabetes mellitus was the most investigated disease (14 out of 42 studies), followed by obesity (11 studies) and cardiovascular diseases (5 studies). A total of 40 reviews reported on the characteristics of included studies, and, as per the AMSTAR scale, 39 reviews had an a priori design. The number of reviews that fulfilled the status of publication criterion was the lowest (7 reviews only), followed by the number used in the assessment of publication bias (11 reviews). The number of high-quality reviews was higher with the OQAQ than with the AMSTAR checklist (33 vs 25 studies), but the AMSTAR showed a higher number of medium-quality reviews than the OQAQ (14 vs 6 studies). Both showed the same number of low-quality reviews. CONCLUSIONS High-quality SRs and MAs are crucial to understanding the relationship between systemic and periodontal diseases. Medical practitioners must be able to inform patients about oral health and specific periodontal health concerns.

Abstract
We used flow cytometry to compare the phagocytic activity of monocytes against Staphylococcus aureus strains (both biofilm and planktonic cells) isolated from denture wearers and non-wearers. Staphylococcal strains were cultured in Brain Heart Infusion broth in both planktonic and biofilm form and were stained with a fluorescent reporter (propidium iodide) and incubated with monocytes. The fluorescence of the monocytes containing phagocytized bacteria was determined by flow cytometry and normalized to that of the bacterial strains used in the experiment. Staphylococcal strains from denture wearers caused greater activation of monocytes but were less prone to phagocytosis. The percentage of monocytes containing bacterial cells after exposition to staphylococcal strains varied from 2.7% to 81.4% for planktonic cells. For biofilm-released cells, this value ranged from 0.6% to 36.2%. The effectiveness of phagocytosis, estimated based on an increase in monocyte fluorescence, amounted to 32.4 and 71 FL2 units for the biofilm and planktonic cells, respectively. The lesser efficiency of phagocytosis against biofilm S. aureus in denture wearers suggests that they might have been colonized with the strains which were less prone to eradication than those from non-wearers.

Abstract
ABSTRACT Objective: to manage the risk of bronchoaspiration in patients with oropharyngeal dysphagia through signalizing plates in the hospital bed. Methods: a descriptive, quantitative study, developed in the medical clinic I (diagnostic investigation), medical clinic II (infectology / pneumology), surgical clinics and intensive care unit of the University Hospital of the Federal University of Sergipe, from February to August 2017. It was composed of patients in the age group ≥ 18 years of age, of both sexes, diagnosed with oropharyngeal dysphagia, based on the application of the adapted protocol of clinical evaluation in the hospital bed and instrumental examination of swallowing, when pertinent. Following the clinical evaluation and identification of the risk of bronchoaspiration due to oropharyngeal dysphagia, the signs were inserted at the hospital bed by the speech therapist. Results: the study included 43 patients at risk of bronchoaspiration due to oropharyngeal dysphagia, average age of 53.7 ± 3.53 years old, with 51.1% (n = 22) females and 48.9% (n = 21) males. A predominance of neuropathies (53.4%) and severe neurogenic oropharyngeal dysphagia (37.2%) was observed. The intensive care unit stood out with 44.18% (n = 19) of the application of signs of risk of bronchoaspiration. Conclusion: the management of bronchoaspiration risk has been shown to be a promising measure to reduce adverse events, which affect the patient's safety and consequently the quality of care in the hospital environment, as well as a possible strategy for measuring respiratory complications triggered by aspiration of oropharyngeal contents.

Abstract
The aim of this study was to develop a theoretical model to describe the role that the dentist plays in Brazilian hospital settings. This qualitative study was based on the grounded theory research method. Participants were a total of 27 individuals in three groups: dentists and general practice and oral and maxillofacial surgery residents; faculty; and other health professionals who interacted with dental patients in the hospital setting during the 2012-13 year. Data were collected in three teaching hospitals in the state of Santa Catarina, Brazil, through scripted interviews using open-ended questions. The stages of collection, codification, ordination, and integration of data were guided by constant comparative techniques to formulate a theoretical model. The codes generated were organized into seven categories: identifying the hospital as a working and teaching environment; recalling the dentists' professional pathways; reflecting on the dentist's work in the hospital; considering the political and organizational dimension of the role of the dentist in the hospital; understanding patients' life and health contexts; education and professional practice; and moving on towards interdisciplinary practices in the hospital setting. Integrating the categories led to a theoretical model called "The Dentist's Role in the Hospital Setting: An Interdisciplinary Construction." This theoretical model provides a framework to understand how dentists perform in the hospital setting, with a focus on interdisciplinary practice, which in this study was shown to be incipient and heterogeneous.

Abstract
Epidemiological studies use saliva on a regular basis as a non-invasive and easy-to-take sample, which is assumed to be a microbial representative of the oral cavity ecosystem. However, comparative studies between different kinds of saliva samples normally used in microbial studies are scarce. The aim of the current study was to compare oral microbiota composition between two different saliva samples collected simultaneously: non-stimulated saliva with paper points and stimulated saliva collected after chewing paraffin gum. DNA was extracted from saliva samples of ten individuals, then analyzed by 16S rRNA pyrosequencing to describe bacterial diversity. The results demonstrate significant differences between the microbiota of these two kinds of saliva. Stimulated saliva was found to contain an estimated number of species over three times higher than unstimulated saliva. In addition, bacterial composition at the class and genus level was radically different between both types of samples. When compared to other oral niches, both types of saliva showed some similarity to tongue and buccal mucosa, but they do not correlate at all with the bacterial composition described in supra- or sub-gingival dental plaque, questioning their use in etiological and epidemiological studies of oral diseases of microbial origin.

Abstract
Pneumonia is one of the most common infectious diseases with a high mortality, especially in the elderly population. To date, there have been only a few population-based studies dealing with the incidence of pneumonia in nursing homes (NHs). We conducted a cohort study using data from a large German statutory health insurance fund. Between 2010 and 2014, 127 227 NH residents 65 years and older were analysed. For the calculation of incidences per 100 person-years (PY) and 95% confidence intervals (CIs), we assessed the first diagnosis of pneumonia during the time in NH. We compared the rates between sexes, age groups, care levels, and comorbidities and we performed a multivariate Cox regression analysis. The mean age in the cohort was 84.0 years (74.6% female). A total of 19 183 incident cases led to an overall 5-year-incidence of 11.8 per 100 PY (95% CI 11.7-12.0). The incidence in men was substantially higher than in women. Rates were highest in the first month after NH placement. Our study revealed that the incidence of pneumonia is high in German NH residents and especially in males. Due to demographic changes, pneumonia will likely be increasingly relevant in the health care of the elderly and institutionalised population.

Abstract
The oral microbiome is diverse in its composition due to continuous contact of oral cavity with the external environment. Temperatures, diet, pH, feeding habits are important factors that contribute in the establishment of oral microbiome. Both culture dependent and culture independent approaches have been employed in the analysis of oral microbiome. Gene-based methods like PCR amplification techniques, random amplicon cloning, PCR-RELP, T-RELP, DGGE and DNA microarray analysis have been applied to increase oral microbiome related knowledge. Studies revealed that microbes from the phyla Firmicutes, Proteobacteria, Bacteroidetes, Actinobacteria, Fusobacteria, Neisseria, TM7 predominately inhabits the oral cavity. Culture-independent molecular techniques revealed the presence of genera Megasphaera, Parvimonas and Desulfobulbus in periodontal disease. Bacteria, fungi and protozoa colonize themselves on various surfaces in oral cavity. Microbial biofilms are formed on the buccal mucosa, dorsum of the tongue, tooth surfaces and gingival sulcus. Various studies demonstrate relationship between unbalanced microflora and development of diseases like tooth caries, periodontal diseases, type 2 diabetes, circulatory system related diseases etc. Transcriptome-based remodelling of microbial metabolism in health and disease associated states has been well reported. Human diets and habitat can trigger virus activation and influence phage members of oral microbiome. As it is said, "Mouth, is the gateway to the total body wellness, thus oral microbiome influences overall health of an individual".

Abstract
Oral diseases, such as caries and periodontitis, not only have local effects on the dentition and on tooth-supporting tissues but also may impact a number of systemic conditions. Emerging evidence suggests that poor oral health influences the initiation and/or progression of diseases such as atherosclerosis (with sequelae including myocardial infarction and stoke), diabetes mellitus and neurodegenerative diseases (such as Alzheimer's disease, rheumatoid arthritis and others). Aspiration of oropharyngeal (including periodontal) bacteria causes pneumonia, especially in hospitalized patients and the elderly, and may influence the course of chronic obstructive pulmonary disease. This article addresses several pertinent aspects related to the medical implications of periodontal disease in the elderly. There is moderate evidence that improved oral hygiene may help prevent aspiration pneumonia in high-risk patients. For other medical conditions, because of the absence of well-designed randomized clinical trials in elderly patients, no specific guidance can be provided regarding oral hygiene or periodontal interventions that enhance the medical management of older adults.

Abstract
Implementation and dissemination of an oral care initiative enhanced the safety and well-being of Veterans at the Salem VA Medical Center by reducing the risk of non-ventilator-associated hospital-acquired pneumonia (NV-HAP). The incidence rate of non-ventilator-associated hospital-acquired pneumonia decreased from 105 cases to 8.3 cases per 1000 patient-days (by 92%) in the initial VA pilot, yielding an estimated cost avoidance of $2.84 million and 13 lives saved in 19 months postimplementation. The team was successful in translating this research into a meaningful quality improvement intervention in 8 VA hospitals (in North Carolina, Texas, and Virginia) that has promoted effective and consistent delivery of oral care across hospital service lines and systems, improved the health of Veterans, and driven down health care costs associated with this largely preventable illness. The steps needed for successful replication and dissemination of this nurse-led, evidence-based practice are summarized in this article.

Abstract
The oral health of older people in acute hospitals has rarely been studied. Hospital admission provides a prime opportunity for identification and rectification of problems, and oral health promotion. This two-part article explores oral hygiene and mouth care provision for older adults in acute hospitals. The first article presents the findings of a literature review exploring oral and dental disease in older adults, the importance of good oral health and mouth care, and the current situation. Searches of electronic databases and the websites of relevant professional health service bodies in the UK were undertaken to identify articles and guidelines. The literature shows a high prevalence of oro-dental disease in this population, with many known detrimental effects, combined with suboptimal oral hygiene and mouth care provision in acute hospitals. Several guidelines exist, although the emphasis on oral health is weaker than other aspects of hospital care. Older adults admitted to acute hospitals have a high burden of oro-dental disease and oral and mouth care needs, but care provision tends to be suboptimal. The literature is growing, but this area is still relatively neglected. Great potential exists to develop oral and mouth care in this context. The second part of this article explores clinical recommendations.

Abstract
R. officinalis L. is an aromatic plant commonly used as condiment and for medicinal purposes. Biological activities of its extract were evaluated in this study, as antimicrobial effect on mono- and polymicrobial biofilms, cytotoxicity, anti-inflammatory capacity, and genotoxicity. Monomicrobial biofilms of Candida albicans, Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans and Pseudomonas aeruginosa and polymicrobial biofilms composed of C. albicans with each bacterium were formed in microplates during 48 h and exposed for 5 min to R. officinalis L. extract (200 mg/mL). Its cytotoxic effect was examined on murine macrophages (RAW 264.7), human gingival fibroblasts (FMM-1), human breast carcinoma cells (MCF-7), and cervical carcinoma cells (HeLa) after exposure to different concentrations of the extract, analyzed by MTT, neutral red (NR), and crystal violet (CV) assays. The anti-inflammatory activity was evaluated on RAW 264.7 non-stimulated or stimulated by lipopolysaccharide (LPS) from Escherichia coli and treated with different concentrations of the extract for 24 h. Interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) were quantified by ELISA. Genotoxicity was verified by the frequency of micronuclei (MN) at 1000 cells after exposure to concentrations of the extract for 24 h. Data were analyzed by T-Test or ANOVA and Tukey Test ( P ≤ 0.05). Thus, significant reductions in colony forming units per milliliter (CFU/mL) were observed in all biofilms. Regarding the cells, it was observed that concentrations ≤ 50 mg/mL provided cell viability of above 50%. Production of proinflammatory cytokines in the treated groups was similar or lower compared to the control group. The MN frequency in the groups exposed to extract was similar or less than the untreated group. It was shown that R. officinalis L. extract was effective on mono- and polymicrobial biofilms; it also provided cell viability of above 50% (at ≤ 50 mg/mL), showed anti-inflammatory effect, and was not genotoxic. Impact statement Rosmarinus officinalis L. extract effectively contributed to in vitro control of important species of microorganisms such as Candida albicans, Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans, and Pseudomonas aeruginosa in mono- and polymicrobial biofilms that are responsible for several infections in oral cavity as in other regions of the body. Furthermore, this extract promoted also cell viability above 50% at concentrations ≤ 50 mg/mL, excellent anti-inflammatory effect, showing inhibition or reduction of the synthesis of proinflammatory cytokines, being also non-genotoxic to cell lines studied. Thus, this extract may be a promising therapeutic agent that can be added in some medical and dental formulations such as toothpastes, mouthwashes, irrigating root canals, ointments, soaps, in order to control pathogenic microorganisms and biofilms, with anti-inflammatory effect and absence of cytotoxic and genotoxic.

Abstract
Ventilator-associated pneumonia (VAP) is one of the commonest hospital-acquired infections associated with high mortality. VAP pathogenesis is closely linked to organisms colonizing the endotracheal tube (ETT) such as Staphylococcus epidermidis and Pseudomonas aeruginosa, the former a common commensal with pathogenic potential and the latter a known VAP pathogen. However, recent gut microbiome studies show that pathogens rarely function alone. Hence, we determined the ETT microbial consortium co-colonizing with S. epidermidis or P. aeruginosa to understand its importance in the development of VAP and for patient prognosis. Using bacterial 16S rRNA and fungal ITS-II sequencing on ETT biomass showing presence of P. aeruginosa and/or S. epidermidis on culture, we found that presence of P. aeruginosa correlated inversely with patient survival and with bacterial species diversity. A decision tree, using 16S rRNA and patient parameters, to predict patient survival was generated. Patients with a relative abundance of Pseudomonadaceae <4.6% and of Staphylococcaceae <70.8% had the highest chance of survival. When Pseudomonadaceae were >4.6%, age of patient <66.5 years was the most important predictor of patient survival. These data indicate that the composition of the ETT microbiome correlates with patient prognosis, and presence of P. aeruginosa is an important predictor of patient outcome.

Abstract
AIM To critically appraise recent research into associations between periodontal disease and systemic diseases and conditions specifically respiratory disease, chronic kidney disease, rheumatoid arthritis, cognitive impairment, obesity, metabolic syndrome and cancer. METHODS A MEDLINE literature search of papers published between 2002 and April 2012 was conducted. Studies that included periodontitis as an exposure were identified. Cross-sectional epidemiological investigations on large samples, prospective studies and systematic reviews formed the basis of the narrative review. A threshold set for the identification of periodontitis was used to identify those studies that contributed to the conclusions of the review. RESULTS Many of the investigations were cross-sectional secondary analyses of existing data sets in particular the NHANES studies. There were a small number of systematic reviews and prospective studies. There was substantial variability in the definitions of exposure to periodontitis. A small number of studies met the threshold set for periodontitis and supported associations; however, in some of the chronic diseases there were no such studies. There was strong evidence from randomized controlled trials that interventions, which improve oral hygiene have positive effects on the prevention of nosocomial pneumonias. CONCLUSIONS There was substantial heterogeneity in the definitions used to identify periodontitis and very few studies met a stringent threshold for periodontitis. Published evidence supports modest associations between periodontitis and some, although not all, of the diseases and conditions reviewed. There is a need to reach a consensus on what constitutes periodontitis for future studies of putative associations with systemic diseases.

Abstract
Pneumonia is an important infectious entity that affects residents in long-term care facilities (LTCFs), whereas hospitalization-requiring pneumonia (HRP) represents a more critical patient condition with worse outcomes. The evidence addressing the association between Barthel index and risk of HRP among LTCF residents is lacking. A multicenter, retrospective cohort study was conducted in three LTCFs enrolling adult patients who resided for 3 months or more and ever underwent Barthel index evaluation within a study period of January 1 to December 31, 2010. The endpoint was HRP after enrollment. A total of 299 patients (169 women; age, 79.0 ± 12.2 years) were enrolled and categorized into HRP Group (n = 68; 36 women; age, 79.1 ± 11.3 years) and Non-HRP Group (n = 231; 133 women; age, 79.0 ± 12.4 years) by the endpoint. The patients in HRP Group had significantly lower Barthel index (8.6 versus 25.8 points, p < 0.001) but higher proportion of chronic obstructive pulmonary disease (13.2% versus 3.9%, p = 0.004). By the multivariate analysis of logistic regression, we found that lower Barthel index (odds ratio (OR), 0.967; p < 0.001), existence of chronic obstructive pulmonary disease (OR, 4.192; p = 0.015), and feeding route (percutaneous endoscopic gastrostomy comparing with oral feeding; OR, 0.177; p = 0.012) were independently associated with HRP. In conclusion, a lower Barthel index is significantly associated with the occurrence of pneumonia that requires hospitalization in long-term care residents. Barthel index is a useful and reliable tool for risk evaluation in this population.

Abstract
Noma is a necrotizing ulcerative stomatitis known since Antiquity. It occurs mostly in poor countries, the Sahel countries being the most affected. Each year, several hundred thousand cases are reported. Noma affects especially malnourished children who are less than 6 years old and rarely adults with acquired immunodeficiency (HIV, cancer). Ulcerative lesion is occurring rapidly due to the production of endotoxins by bacteria from oral commensal, telluric and animal origin. Necrotic debridement leads to huge defects: loss of soft tissue (skin, nerves, vessels, eye), bone (maxilla, mandible) and teeth. Death occurs rapidly in a few weeks in 80 % of the cases. In case of survival, the consequences are functional, aesthetic, psychological and social. The goal of the treatment in the acute phase is the patient's survival and the fight against limited mouth opening. The management of the phase of sequela is an anaesthetic, surgical and physiotherapy challenge. Its purpose is the social reintegration of the patient.

Abstract
AIM We evaluated the periodontal health status and oral health behavior among hospitalized patients with chronic obstructive pulmonary disease (COPD) to assess the association of COPD with dental health. MATERIALS AND METHODS A group of 100 hospitalized patients with COPD and a group of 100 age, sex, and race-matched control patients were included in this study. Detailed case histories along with standardized measures of oral health including gingival index, plaque index (PI), and simplified oral hygiene index (OHI) were estimated and compared. Probing depths and clinical attachment levels (CALs) were recorded at four sites per tooth. C-reactive protein (CRP) levels in saliva and serum were also measured. RESULTS The study subjects had similar demographics and distribution in either group. Patients with COPD had significantly lower brushing frequency, poor periodontal health (OHI and PI), greater gingival inflammation, and deeper pockets/CALs compared to controls. Further COPD patients had significantly higher serum and salivary CRP levels compared to control groups. CONCLUSIONS Lower brushing frequency, poor oral health, and presence of destructive periodontal disease were observed among patients with COPD, which warrants promoting dental care and oral health knowledge as an integrated approach to treating COPD patients.

Abstract
Cystic fibrosis (CF) is the most frequent lethal genetic disease in the Caucasian population. Lung destruction is the principal cause of death by chronic Pseudomonas aeruginosa colonization. There is a high prevalence of oropharyngeal anaerobic bacteria in sputum of CF patients. This study was carried out due to the lack of results comparing subgingival periodontal pathogenic bacteria between the oral cavity and lungs in patients with CF in relation with P. aeruginosa presence. Our first goal was to detect P. aeruginosa in oral and sputum samples by culture and molecular methods and to determine clonality of isolates. In addition, subgingival periodontal anaerobic bacteria were searched for in sputum. A cross-sectional pilot case-control study was conducted in the CF Reference Center in Roscoff, France. Ten CF patients with a ΔF508 homozygous mutation (5 chronically colonized [CC] and 5 not colonized [NC]) were enrolled. P. aeruginosa was detected in saliva, sputum, and subgingival plaque samples by real-time quantitative PCR (qPCR). Subsequently, periodontal bacteria were also detected and quantified in subgingival plaque and sputum samples by qPCR. In CC patients, P. aeruginosa was recovered in saliva and subgingival plaque samples. Sixteen P. aeruginosa strains were isolated in saliva and sputum from this group and compared by pulsed-field gel electrophoresis (PFGE). Subgingival periodontal anaerobic bacteria were found in sputum samples. A lower diversity of these species was recovered in the CC patients than in the NC patients. The presence of the same P. aeruginosa clonal types in saliva and sputum samples underlines that the oral cavity is a possible reservoir for lung infection.

Abstract
OBJECTIVE To examine the prevalence of healthcare-associated pathogens and the infection control policies and practices in a national sample of nursing homes (NHs). METHODS In 2012, we conducted a national survey about the extent to which NHs follow suggested infection control practices with regard to 3 common healthcare-associated pathogens: methicillin-resistant Staphylococcus aureus, Clostridium difficile, and extended-spectrum β-lactamase producers, and their prevalence in NHs. We adapted a previously used and validated NH infection control survey, including questions on prevalence, admission and screening policies, contact precautions, decolonization, and cleaning practices. RESULTS A total of 1,002 surveys were returned. Of the responding NHs, 14.2% were less likely to accept residents with methicillin-resistant Staphylococcus aureus, with the principal reason being lack of single or cohort rooms. NHs do not routinely perform admission screening (96.4%) because it is not required by regulation (56.2%) and would not change care provision (30.7%). Isolation strategies vary substantially, with gloves being most commonly used. Most NHs (75.1%) do not decolonize carriers of methicillin-resistant Staphylococcus aureus, but some (10.6%) decolonize more than 90% of residents. Despite no guidance on how resident rooms on contact precautions should be cleaned, 59.3% of NHs report enhanced cleaning for such rooms. CONCLUSION Overall, NHs tend to follow voluntary infection control guidelines only if doing so does not require substantial financial investment in new or dedicated staff or infrastructure.
