Elderly patients with systemic disorders and immunocompromised patients seem to have a higher risk of developing morbidity from COVID-19. <i>Candida albicans</i> (<i>C. albicans</i>) is a potentially dangerous pathogen for these patients, especially for denture wearers with prosthetic stomatitis who require mechanical ventilation. <i>C. albicans</i> infection, the main candidiasis infection associated with denture wear, can complicate COVID-19 and increase the associated morbidity and mortality. Therefore, early diagnosis of <i>C. albicans</i> infection in COVID-19 patients is important to establish more effective antifungal treatment methods and prophylaxis strategies. Hospitalized COVID-19 patients should undergo an oral examination to assess their oral health, and those with poor oral health should receive the appropriate care and monitoring.

AbstractChronic hyperplastic candidiasis (CHC), earlier known as candidal leukoplakia, is a variant of oral candidiasis that classically presents as a white patch on the commissures of the oral mucosa and it is mostly caused by Candida albicans. Clinically, the lesions are usually asymptomatic and regress after appropriate antifungal therapy and correction of the underlying cause. If the lesions are untreated, a small portion may develop dysplasia and later progress into carcinoma. The purpose of this article is to report a case of CHC in a 57-year-old male patient with a significant smoking habit, who presented with a thick, nonscrapable, brownish-white coating on the dorsum of the tongue for 9 years. This case is of particular importance and concern because of the high risk for malignant transformation in CHC. The role of biopsy and histopathology is also stressed through this case report in arriving at a definitive diagnosis and treatment planning. Further, this case is interesting because it was refractory to local and systemic antifungal treatment and so, surgery was chosen as an alternative treatment modality considering the side effects of the prolonged use of antifungal drugs.

Background: Patients’ oral health is impaired in Intensive Care units (ICUs) due to loss of consciousness, open mouth, intubation, and mechanical ventilation. Objectives: The current study aimed to compare the effects of comprehensive and combined programs on oral health in patients under mechanical ventilation. Methods: This single-blind clinical trial with three groups was performed on 90 patients with mechanical ventilation admitted to ICUs of medical centers affiliated to the Zahedan University of Medical Sciences, Iran, in 2020. Patients under mechanical ventilation were randomly divided into three groups, including those receiving a comprehensive program, those receiving a combined program, and controls through permutated blocks. In the two intervention groups, oral care was performed for 5 minutes, three times per day, during the 5 days of the study with a specific method. The control group received routine oral care. The patients’ oral health was measured once before the intervention and then every day until the fifth day of the intervention using the Beck Oral Assessment scale. The data were analyzed using the analysis of variance and chi-square in IBM SPSS Statistics software version 26. Results: The mean oral health score in the three groups was not significantly different before the intervention and on the second day of the study (P > 0.05). However, on the third to fifth days of the study, the oral health score in the two intervention groups showed a significant decrease compared to the control group, indicating an oral health improvement in these groups (P = 0.001). The mean oral health score in the control group increased during the study days. Conclusions: Comprehensive care and combination methods can improve oral health in patients under mechanical ventilation. Nurses are recommended to use regular and codified oral care methods.

ABSTRACTOral candidiasis is often accompanied by severe inflammation, resulting in a decline in the quality of life of immunosuppressed individuals and elderly people. To develop a new oral therapeutic option for candidiasis, a nonpathogenic commensal oral probiotic microorganism,Streptococcus salivariusK12, was evaluated for its ability to modulateCandida albicansgrowthin vitro, and its therapeutic activity in an experimental oral candidiasis model was tested.In vitroinhibition of mycelial growth ofC. albicanswas determined by plate assay and fluorescence microscopy. Addition ofS. salivariusK12 to modified RPMI 1640 culture medium inhibited the adherence ofC. albicansto the plastic petri dish in a dose-dependent manner. Preculture ofS. salivariusK12 potentiated its inhibitory activity for adherence ofC. albicans. Interestingly,S. salivariusK12 was not directly fungicidal but appeared to inhibitCandidaadhesion to the substratum by preferentially binding to hyphae rather than yeast. To determine the potentially anti-infective attributes ofS. salivariusK12 in oral candidiasis, the probiotic was administered to mice with orally induced candidiasis. Oral treatment withS. salivariusK12 significantly protected the mice from severe candidiasis. These findings suggest thatS. salivariusK12 may inhibit the process of invasion ofC. albicansinto mucous surfaces or its adhesion to denture acrylic resins by mechanisms not associated with the antimicrobial activity of the bacteriocin.S. salivariusK12 may be useful as a probiotic as a protective tool for oral care, especially with regard to candidiasis.

Oral health is integrally linked to overall well-being. This article describes a research program focused on the contribution of poor oral health to systemic illness. Initial investigations examined factors related to streptococcal virulence that were important in dental caries and endocarditis and led to development of immunization strategies in animal models to reduce risk of endocarditis. Clinical investigations related to critically ill adults began with descriptive and observational studies that established the importance of dental plaque in development of ventilator-associated pneumonia (VAP) and examined existing nursing practices in oral care. Subsequent intervention studies sponsored by the National Institutes of Health (NIH) to test oral care protocols in critically ill adults have built on that foundation. The group’s first NIH-funded randomized clinical trial tested the effects of toothbrushing and use of chlorhexidine in reducing risk of VAP in critically ill adults and showed that VAP was reduced by topical application of chlorhexidine initiated after intubation, although toothbrushing did not reduce VAP. The study had a rapid and dramatic effect on clinical practice. Results of the study were published in September 2009 in the American Journal of Critical Care, and in May 2010, the Institute for Health-care Improvement updated the recommendations for the care of patients receiving mechanical ventilation (the ventilator bundle) to include daily oral care with chlorhexidine, referencing the results of that study as evidence for the change. Chlorhexidine is now the standard of care for adults receiving mechanical ventilation. Because the effects of chlorhexidine after intubation were so beneficial, a second recently completed NIH-funded randomized clinical trial investigated the impact of chlorhexidine applied before intubation compared with after intubation. Currently a large randomized clinical trial is being launched to determine the optimal frequency of toothbrushing for critically ill patients receiving mechanical ventilation in an effort to maximize oral health benefits while minimizing systemic risks. The importance of collaboration and mentoring in building nursing science is discussed. Future directions for research also are explored.

Exciting Time

Pregnancy is a unique, exciting time in a woman's life, and there are so many changes going on in human body during pregnancy and mouth is no exception , so good oral hygiene is extremely important during pregnancy . Usually oral health is often the most neglected form of health during all stages of life & the most important cause for this neglection is lack of awareness among people & this problems also increases when a lady is pregnant because of mis-perceptions and mis-leading information in the society or due to lack of knowledge. But the fact is during pregnancy many complex physiologic changes occur in the women’s body, which can adversely affect oral health and in turn those oral health problems may lead to pregnancy outcomes like preterm birth or low birth weight. Proper oral care is of utmost importance during pregnancy to avoid these complications. Avoiding foods that may cause oral problems, proper brushing and flossing and having dental consultations on a regular basis are steps to ensure good oral health during pregnancy.

Candida albicans, a commensal fungus of the oral microbiome, causes oral candidiasis in humans with localized or systemic immune deficiencies. Secreted aspartic proteinases (Saps) are a family of 10 related proteases and are virulence factors due to their proteolytic activity, as well as their roles in adherence and colonization of host tissues. We found that mice infected sublingually withC. albicanscells overexpressing Sap6 (SAP6OE and a Δsap8strain) had thicker fungal plaques and more severe oral infection, while infection with the Δsap6strain was attenuated. These hypervirulent strains had highly aggregative colony structurein vitroand higher secreted proteinase activity; however, the levels of proteinase activity ofC. albicansSaps did not uniformly match their abilities to damage cultured oral epithelial cells (SCC-15 cells). Hyphal induction in cells overexpressing Sap6 (SAP6OE and Δsap8cells) resulted in formation of large cell-cell aggregates. These aggregates could be produced in germinated wild-type cells by addition of native or heat-inactivated Sap6. Sap6 bound only to germinated cells and increasedC. albicansadhesion to oral epithelial cells. The adhesion properties of Sap6 were lost upon deletion of its integrin-binding motif (RGD) and could be inhibited by addition of RGD peptide or anti-integrin antibodies. Thus, Sap6 (but not Sap5) has an alternative novel function in cell-cell aggregation, independent of its proteinase activity, to promote infection and virulence in oral candidiasis.

Introduction: Rates of periodontal disease and tooth loss are increased in individuals with rheumatoid arthritis (RA). Understanding factors that contribute to the increased burden of periodontal disease in RA is critical to improving oral health and arthritis outcomes. Objectives: To determine the perceptions held by people with RA relating to their oral health, to identify patient-centered priorities for oral health research, and to inform optimal strategies for delivering oral health knowledge. Methods: Semistructured interviews were conducted with patients with RA. Recorded interview transcripts were iteratively reviewed to reveal surface and latent meaning and to code for themes. Constructs were considered saturated when no new themes were identified in subsequent interviews. We report themes with representative quotes. Results: Interviews were conducted with 11 individuals with RA (10 women [91%]; mean age, 68 y), all of whom were taking RA medication. Interviews averaged 19 min (range, 8 to 31 min) and were mostly conducted face-to-face. Three overall themes were identified: 1) knowledge about arthritis and oral health links; 2) oral health care in RA is complicated, both in personal hygiene practices and in professional oral care; and 3) poor oral health is a source of shame. Participants preferred to receive oral health education from their rheumatologists or dentists. Conclusions: People with RA have unique oral health perceptions and experience significant challenges with oral health care due to their arthritis. Adapting oral hygiene recommendations and professional oral care delivery to the needs of those with arthritis are patient priorities and are required to improve satisfaction regarding their oral health. Knowledge Translation Statement: Patients living with long-standing rheumatoid arthritis described poor oral health–related quality of life and multiple challenges with maintaining optimal oral health. Study findings indicate a need for educational materials addressing oral health maintenance for patients with rheumatic diseases and their providers.
