The Challenge of Medication-Induced Dry Mouth in Residential Aged Care

Subjectively Low Oral Function Is Associated With Physical Frailty and Polypharmacy in Community-Dwelling Older Adults

OBJECTIVE

To examine each Kihon Checklist (KCL) oral function item, physical function, and the number of medications and describe associations between KCL oral function, frailty, sarcopenia, and polypharmacy.

METHODS

Participants were 318 community-dwelling older adults (78.6 ± 6.9 years). The number of medications, KCL, the Japanese version of the Cardiovascular Health Study (J-CHS), grip strength, gait speed, and skeletal muscle index were measured. Analyses used cross-tabulation. Logistic regression modelled the presence of low oral function.

RESULTS

Of the three oral function questions on the KCL, 34.9% of participants answered "yes" to Q13 on mastication, 24.8% answered "yes" to Q14 on swallowing, and 31.4% answered "yes" to Q15 on dry mouth. A total of 25.2% of the participants had low oral function according to the KCL. More of those with low oral function had polypharmacy. Oral function was not associated with sarcopenia. Physical frailty was associated with low oral function. Logistic regression analysis with oral function as the dependent variable and age, sex, polypharmacy, physical frailty, and sarcopenia status as the independent variables showed that physical frailty was associated with it.

CONCLUSION

Older people who are physically frail and taking multiple medications are likely also to have oral frailty.

Medical Practitioners' Views on Barriers in Collaboration with Dentists in Long-Term Care Settings

INTRODUCTION

In long-term care settings (LTCs), oral health care often remains fragmented from other geriatric care services. Medical practitioners (MPs) typically take the lead in addressing medical aspects of geriatric care plans, making it essential for them to understand the importance of oral health and to collaborate with dental professionals. However, little is known about MPs' perceptions toward oral health management in LTCs. This qualitative study aimed to gain an in-depth understanding of MPs' views on oral health management in LTCs and explore challenges in collaborating with dental professionals in Singapore.

METHODS

Participants were recruited using a purposive sampling strategy, initially through targeted outreach to those with experience in LTCs, followed by snowball sampling to identify additional participants until data saturation was achieved. One-to-one interviews with participants were conducted via teleconferencing using a semi-structured interview guide. The transcripts were analyzed using a hybrid (inductive and deductive) thematic analysis supported by NVivo data management software.

RESULTS

Participants (n = 13) felt that oral health care was currently not well-integrated into the existing LTC system. They frequently encountered oral health issues but arranged for dental appointments only when their patients complained of acute symptoms. Key barriers identified were (1) a cultural misconception within the eldercare community that poor oral health was an inevitable part of aging, (2) systemic barriers related to the inadequate geriatric oral health care services and infrastructure, and (3) knowledge gaps in geriatric oral health management among MPs. These factors collectively hindered effective collaboration with dental professionals in LTCs.

CONCLUSION

Participants emphasized the lack of oral health care integration in LTCs, identifying cultural, systemic, and internal barriers. Strengthening collaboration with dental professionals in LTCs, implementing oral health education for the eldercare community, and introducing domiciliary services could address these challenges and support more effective geriatric care, with insights for similar systems globally.

KNOWLEDGE TRANSFER STATEMENT

This qualitative study highlighted a critical gap in oral health care integration within eldercare described by the MPs in this study in Singapore's long-term care settings. Although findings are context specific, they may offer insights for aging nations facing similar challenges. Overcoming misconceptions about aging and oral health, improving systems, and educating MPs are key to fostering interdisciplinary collaboration and enhancing eldercare. Addressing these barriers could improve the overall well-being of care-dependent older adults.

Saliva as a Diagnostic Tool for Systemic Diseases-A Narrative Review

Saliva has emerged as a powerful diagnostic tool due to its non-invasive collection, straightforward storage, and ability to mirror systemic health. This narrative review explores the diagnostic potential of salivary biomarkers in detecting systemic diseases, supported by examples such as salivary proteomics' role in monitoring endocrine disorders, cancer, and viral infections. Advances in technologies like microfluidics, biosensors, and next-generation sequencing have enhanced the sensitivity and specificity of salivary diagnostics, making it a viable alternative to blood-based diagnostics. The review also evaluates challenges such as the need for standardized collection protocols, variability in salivary composition, and the integration of these technologies into clinical workflows. The findings emphasize the transformative potential of saliva in personalized medicine, especially for early disease detection and real-time health monitoring. Practical applications include its use in mass screenings and public health crises, highlighting saliva as a cornerstone for future advancements in non-invasive diagnostics.

Use of the modified Schirmer test to measure salivary gland hypofunction/hyposalivation: Systematic review and meta-analysis

Although dry mouth is a relatively common condition, salivary flow is not routinely measured in dental clinical practice. Moreover, existing data regarding the use of the modified Schirmer test (MST) for the screening of dry mouth has not been summarized. This systematic review and meta-analysis, conducted in accordance with the PRISMA guidelines, aimed to determine whether the modified Schirmer test can be used to identify dry mouth. The databases of PubMed, Scopus, ScienceDirect, and CENTRAL (CRD42023393843) were systematically searched to retrieve articles published until 9th November 2023. Among the 343 original articles retrieved, six met the inclusion criteria. A total of 1150 patients, comprising 710 (61.7%) women and 440 (38.3%) men (mean age, 47.1 ± 7.3 years), were included. The meta-analysis revealed a weak correlation coefficient ofr ¯ $\bar{r}$  = 0.42 (95% Cl: 0.29-0.55) between MST and the unstimulated salivary flow rate. Therefore, while the MST might offer a simple and accessible alternative for initial screening in the future, especially in non-specialized settings, its variability in sensitivity and specificity, along with an actual lack of standardization, necessitates cautious interpretation. Further studies are necessary before recommending the test in clinical routine.

Prevalence of complete edentulism among US adults 65 years and older: A Behavioral Risk Factor Surveillance System study from 2012 through 2020

BACKGROUND

The rapid growth of the older adult population in the United States and their increased risk of edentulism make it essential to analyze trends and factors associated with edentulism.

METHODS

Data were obtained from the Behavioral Risk Factor Surveillance System from 2012 through 2020. US- and state-level trend lines were reported. Multiple logistic regression analyses were used to evaluate the association between self-reported complete edentulism and demographic characteristics, chronic diseases, smoking status, and health insurance status. Multiple imputations were used to address the missing data.

RESULTS

A total of 771,513 (weighted n = 50,410,576) participants were included in the study. There was a significant (P = .021) downward trend in the prevalence of edentulism from 2012 (16.36%) through 2020 (13.54%). Having less than a high school education, being a smoker, being non-Hispanic Black, having an annual household income less than $75,000, and having chronic conditions, including diabetes, myocardial infarction, arthritis, depression, and stroke, were significantly associated with complete edentulism.

CONCLUSIONS

Despite a decrease in prevalence of edentulism, disparities based on race, income, and education still exist. Edentulism is associated with chronic diseases in older adults.

PRACTICAL IMPLICATIONS

Public health initiatives should be aimed at reducing the impact of edentulism and improving overall quality of life among older adults. Community health programs allocating resources to improve access to affordable care, reducing precursors to edentulism, expanding dental coverage, and promoting oral and general health awareness are vital components of these efforts.

A Digital Health Perspective on Medication Use and Polypharmacy Management for Improving Healthcare Outcomes in Geriatric Patients

The high prevalence of multiple comorbidities poses unique medication-related challenges for geriatric patients. Polypharmacy is a particular concern since taking several medications simultaneously increases the likelihood of adverse drug events and the risk of drug interactions while decreasing patient adherence. These factors are associated with suboptimal health outcomes and a heightened burden on the healthcare system (insurance claims) and the patient (out-of-pocket expenses). These challenges can significantly affect the quality of life of geriatric patients. This chapter critically examines the impact of medication use and polypharmacy on the quality of life of older patients. In addition, the authors discuss how artificial intelligence-based digital tools and precision medicine can address these issues by streamlining medical decision-making, improving the patient experience, and allowing remote monitoring. Finally, they interpret the findings from the lens of ethical considerations associated with the adoption and implementation of digital applications and gadgets.

Novel Strategies for Orofacial Soft Tissue Regeneration

Significance: Orofacial structures are indispensable for speech and eating, and impairment disrupts whole-body health through malnutrition and poor quality of life. However, due to the unique and highly specialized cell populations, tissue architecture, and healing microenvironments, regeneration in this region is challenging and inadequately addressed to date. Recent Advances: With increasing understanding of the nuanced physiology and cellular responses of orofacial soft tissue, novel scaffolds, seeded cells, and bioactive molecules were developed in the past 5 years to specifically target orofacial soft tissue regeneration, particularly for tissues primarily found within the orofacial region such as oral mucosa, taste buds, salivary glands, and masseter muscles. Critical Issues: Due to the tightly packed and complex anatomy, orofacial soft tissue injury commonly implicates multiple tissue types, and thus functional unit reconstruction in the orofacial region is more important than single tissue regeneration. Future Directions: This article reviews the up-to-date knowledge in this highly translational topic, which provides insights into novel biologically inspired and engineered strategies for regenerating orofacial component tissues and functional units.

[Strategy to optimize patient safety in the community pharmacy dispensing service. Proposed checklists]

Dispensing is the most requested and important service within the tasks performed by the pharmacist, in his day-to-day work, in the community pharmacy. The aim of dispensing is to guarantee the patient's access to the medicine in an adequate and controlled manner. During that process, the community pharmacist has the obligation, as a healthcare professional, to actively participate in a committed manner in the detection of possible medication or medication-related errors.SEFAC´s patient safety group has developed, as the beginning of a series of future projects, checklists and best guidelines for medicines formulated as transdermal patches, modified release forms or orodispersible tablets. The aim of this initiative is to minimize as far as possible, by means of a prior interview with the patient and the use of these tools, any errors or problems that might arise with these drugs, thereby ensuring patient safety.A pilot project is expected to begin throughout 2023 in community pharmacies that collaborate with SEFAC's patient safety group. Therefore, they will be able to collect and report the results obtained.

Xerostomia and Its Cellular Targets

Xerostomia, the subjective feeling of a dry mouth associated with dysfunction of the salivary glands, is mainly caused by radiation and chemotherapy, various systemic and autoimmune diseases, and drugs. As saliva plays numerous essential roles in oral and systemic health, xerostomia significantly reduces quality of life, but its prevalence is increasing. Salivation mainly depends on parasympathetic and sympathetic nerves, and the salivary glands responsible for this secretion move fluid unidirectionally through structural features such as the polarity of acinar cells. Saliva secretion is initiated by the binding of released neurotransmitters from nerves to specific G-protein-coupled receptors (GPCRs) on acinar cells. This signal induces two intracellular calcium (Ca2+) pathways (Ca2+ release from the endoplasmic reticulum and Ca2+ influx across the plasma membrane), and this increased intracellular Ca2+ concentration ([Ca2+]i) causes the translocation of the water channel aquaporin 5 (AQP5) to the apical membrane. Consequently, the GPCR-mediated increased [Ca2+]i in acinar cells promotes saliva secretion, and this saliva moves into the oral cavity through the ducts. In this review, we seek to elucidate the potential of GPCRs, the inositol 1,4,5-trisphosphate receptor (IP3R), store-operated Ca2+ entry (SOCE), and AQP5, which are essential for salivation, as cellular targets in the etiology of xerostomia.

Multiple Chronic Diseases Associated With Tooth Loss Among the US Adult Population

Background

Half of US adults aged 20–64 years have lost at least one permanent tooth; one in six adults aged 65 and over in the USA is edentulous. Tooth loss and edentulism interfere with nutritional intake and quality of life. Although selected chronic diseases (e.g., diabetes) have been identified as possible risk factors for tooth loss, data on multiple chronic diseases and on having two or more concurrent chronic diseases (multimorbidity) in relation to tooth loss are lacking. Therefore, this study aimed to assess the association between multiple chronic diseases, multimorbidity, and tooth loss in US adults.

Methods

We performed a secondary data analysis using the US 2012 Behavioral Risk Factor Surveillance System (BRFSS), a national cross-sectional telephone survey studying health conditions and health behaviors among US adults (≥18 years) who are non-institutionalized residents. Variables were derived from the BRFSS Standard Core Questionnaire. Descriptive analysis including means, standard deviations (SDs), and percentages was calculated. Sample weights were applied. The stepwise multinomial logistic regression method was used to examine the relationship between several chronic diseases and tooth loss. Separate multinomial logistic regression models were used to examine the relationship between multimorbidity and tooth loss among all adults aged more than 18 years, adults aged 18–64 years, and adults aged more than 65 years, respectively.

Results

Among the samples (n = 471,107, mean age 55 years, 60% female), 55% reported losing no tooth loss, 30% reported losing one to five teeth, 10% reported losing six or more but not all teeth, and 5% reported losing all teeth. After adjusting for demographic characteristics, socioeconomic status, smoking, BMI, and dental care, chronic diseases that were associated with edentulism were chronic obstructive pulmonary disease (COPD) [adjusted risk ratio (adj. RR) 2.18, 95% confidence interval (CI) 2.08–2.29]; diabetes (adj. RR 1.49, 95% CI 1.44–1.56); arthritis (adj. RR 1.49, 95% CI 1.44–1.54); cardiovascular disease (adj. RR 1.38, 95% CI 1.30–1.45); stroke (adj. RR 1.31, 95% CI 1.24–1.40); kidney disease (adj. RR 1.16, 95% CI 1.08–1.25); cancer (adj. RR 1.05, 95% CI 1.01–1.11); and asthma (adj. RR 1.07, 95% CI 1.02–1.12). For those who reported losing six or more teeth, the association remained significant for all the chronic diseases mentioned, albeit the magnitude of association appeared to be comparative or smaller. In addition, adults with multimorbidity were more likely to have tooth loss (loss of one to five teeth: adj. RR 1.17, 95% CI 1.14–1.19; loss of six or more teeth: adj. RR 1.78, 95% CI 1.73–1.82; edentulous: adj. RR 2.03, 95% CI 1.96–2.10).

Conclusions

Multiple chronic diseases were associated with edentulism and tooth loss. People with multimorbidity are more likely to be edentulous than those with one or no chronic disease. The findings from this study will help to identify populations at increased risk for oral problems and nutritional deficits, thus the assessment of oral health should be evaluated further as an important component of chronic illness care.

Properties and characteristics of foam denture cleaners as denture adhesive removers

The need for denture adhesives is increasing worldwide, but few denture-care products target denture adhesive users. Foam denture cleaners have been recently marketed to assist brush denture cleaning, but there is a lack of objective evaluation. In this study, we compared the detergency of denture adhesives using six commercial foam-denture cleaners. For removing the adhesives, most of the tested cleaners were effective in immersion experiments, and three cleaners were more effective in the denture cleaning experiment compared to control water. However, only one could effectively remove the slime that is derived from the adhesive and detergency of artificial dirt. The surface roughnesses of the denture base and the relining material revealed that prolonged immersion in some cleaners could be affected. The results suggest that different commercial foam denture cleaners have different detergency levels, and that some cleaners may affect the properties of denture materials upon long-term use.

Evaluation and Treatment in Urology for Nocturia Caused by Nonurological Mechanisms: Guidance from the PLANET Study

Patients with nocturia are commonly referred to urology clinics, including many for whom a nonurological medical condition is responsible for their symptoms. The PLanning Appropriate Nocturia Evaluation and Treatment (PLANET) study was established to develop practical approaches to equip healthcare practitioners to deal with the diverse causes of nocturia, based on systematic reviews and expert consensus. Initial assessment and therapy need to consider the possibility of one or more medical conditions falling into the "SCREeN" areas of Sleep medicine (insomnia, periodic limb movements of sleep, parasomnias, and obstructive sleep apnoea), Cardiovascular (hypertension and congestive heart failure), Renal (chronic kidney disease), Endocrine (diabetes mellitus, thyroid disease, pregnancy/menopause, and diabetes insipidus), and Neurology. Medical and medication causes of xerostomia should also be considered. Some key indicators for these conditions can be identified in urology clinics, working in partnership with the primary care provider. Therapy of the medical condition in some circumstances lessens the severity of nocturia. However, in many cases there is a conflict between the two, in which case the medical condition generally takes priority on safety grounds. It is important to provide patients with a realistic expectation of therapy and awareness of limitations of current therapeutic options for nocturia. PATIENT SUMMARY: Nocturia is the symptom of waking at night to pass urine. Commonly, this problem is referred to urology clinics. However, in some cases, the patient does not have a urological condition but actually a condition from a different speciality of medicine. This article describes how best the urologist and the primary care doctor can work together to assess the situation and make sensible and safe treatment suggestions. Unfortunately, there is sometimes no safe or effective treatment choice for nocturia, and treatment needs to focus instead on supportive management of symptoms.
