An evaluation of serum albumin, root caries, and other covariates in Gullah African Americans with type-2 diabetes

N. S, Singla N, Singhal DK, Singla R. A Cross-Sectional Study to Assess Diabetes as a Risk Factor for Root Caries Amongst the Elderly Population in Udupi District, Karnataka State, India

Objectives

To compare the prevalence of root surface carious lesions among the nondiabetic and diabetic elderly population and its association with various risk factors.

Methods

An observational analytical cross-sectional study was conducted among 800 elderly participants, 431 males and 369 females, aged 50 years and above, with a minimum of ten teeth present, with 400 being diabetic and 400 nondiabetic from the various hospitals of the Udupi district. Demographics, socioeconomic status, oral hygiene practices, oral abusive habits, and history of type 2 diabetes were collected using an interviewer-administered questionnaire followed by an intraoral examination to assess root caries. The primary outcome measure was the presence of any carious or filled root surface. Binary logistic regression univariate analysis was done for all the predictor variables, and those with significant associations were further analyzed by multivariate analysis with the enter method in a single-step model. An appropriate nomogram was designed for risk prediction.

Results

Overall, the root caries prevalence was 37.3%, and the mean root caries index was 14.28%. The prevalence of root caries was 46% in people with diabetes and 28.5% in nondiabetics. Participants with type 2 diabetes, less education, low socioeconomic status, and using finger cleaning had a significantly higher risk of developing root caries. Additionally, those who used removable partial dentures (RPDs) were found to be 4.65 times more likely to have root caries than those who did not use RPDs.

Conclusion

Elderly diabetics are at a higher risk for developing root caries and are strongly advised to maintain good oral hygiene practices and to undergo periodic dental evaluations. Therefore, it is crucial to emphasize early diagnosis and treatment of root caries in this population.

Implication of serum and salivary albumin tests in the recent oral health related epidemiological studies: A narrative review

Albumin is the most abundant protein in human serum and a specific amount of albumin also can be found in the saliva. It has several physiological functions such as blood colloidal osmotic pressure, antioxidant activity, binding and transporting of endogenous and exogenous substrates. We conducted an electronic search across several databases such as PubMed, Scopus, Cochrane, Embase and Science Direct using the relevant MeSH terms and keywords like "albumin", "serum albumin", "salivary albumin", "oral health" "dental caries" and "epidemiology". Only the epidemiological studies published between 2010 and 2023 were included. After the application of the inclusion criteria, a total of 51 studied were included in this narrative review. Serum and salivary albumin tests have been used in various aspects of oral health as a diagnostic and prognostic factor. Some of the results point out to a pattern of association while some of them are inconclusive and even contradictory. This narrative review discusses the role, significance and impact of albumin in epidemiological oral health related studies including the categories of periodontal health and disease, dental caries, oral function and hypofunction, nutrition and malnutrition, tooth loss and its treatment, diabetes and cancer. In addition, it offers a short manual for the researchers on when, where and how to use albumin tests in planning their study designs whether investigating an association or measure them as a covariate.

Impaired Clinical Efficacy of Aspirin in Hypoalbuminemic Patients With Diabetes Mellitus

Objective: To investigate the impact of albumin levels on the aspirin efficacy, since aspirin inhibits platelet aggregation (PA) by cyclooxygenase one irreversible acetylation that is less effective in patients with type 2 diabetes mellitus (T2DM).

Patients and Methods: A total of 612 aspirin (100 mg/day)-treated T2DM patients were followed-up for 54.4 ± 7.3 months. The primary endpoint, a composite of cardiovascular events (CVEs) including CV death, myocardial infarction, ischemic stroke and coronary revascularization, was analysed according to baseline values of serum albumin (≥ or < 3.5 g/dL). Serum thromboxane (Tx)B₂ was also measured.

Results: 250 (40.8%) patients had serum albumin < 3.5 g/dL; these patients were overweight and had higher values of fibrinogen (p = 0.009), high sensitivity C-reactive protein (p = 0.001) and fasting plasma glucose (p < 0.0001) compared to those with albumin ≥ 3.5 g/dL. During follow-up, 86 CVEs were recorded, 49 and 37 in patients with serum albumin < or ≥3.5 g/dL, respectively (p = 0.001). At multivariable Cox regression analysis, serum albumin < 3.5 g/dL (hazard ratio [HR] 1.887, 95% confidence interval [CI] 1.136–3.135, p = 0.014), age (HR 1.552 for every 10 years, 95%CI 1.157–2.081, p = 0.003), fasting plasma glucose (HR 1.063, 95%CI 1.022–1.105, p = 0.002) and beta-blocker use (HR 0.440, 95%CI 0.270–0.717, p = 0.001) were associated to CVEs. Serum TxB₂ levels (n = 377) were 0.32 ± 0.12 and 0.24 ± 0.12 ng/ml in patients with albumin < or ≥ 3.5 g/dL, respectively (p < 0.001).

Conclusion: In T2DM patients, the efficacy of aspirin varies according to albumin levels. Hypoalbuminemia associated with impaired TxB₂ inhibition and an increased risk of long-term CVEs.

Evaluating All Potential Oral Complications of Diabetes Mellitus

Diabetes mellitus (DM) is associated with several microvascular and macrovascular complications, such as retinopathy, nephropathy, neuropathy, and cardiovascular diseases. The pathogenesis of these complications is complex, and involves metabolic and hemodynamic disturbances, including hyperglycemia, insulin resistance, dyslipidemia, hypertension, and immune dysfunction. These disturbances initiate several damaging processes, such as increased reactive oxygen species (ROS) production, inflammation, and ischemia. These processes mainly exert their damaging effect on endothelial and nerve cells, hence the susceptibility of densely vascularized and innervated sites, such as the eyes, kidneys, and nerves. Since the oral cavity is also highly vascularized and innervated, oral complications can be expected as well. The relationship between DM and oral diseases has received considerable attention in the past few decades. However, most studies only focus on periodontitis, and still approach DM from the limited perspective of elevated blood glucose levels only. In this review, we will assess other potential oral complications as well, including: dental caries, dry mouth, oral mucosal lesions, oral cancer, taste disturbances, temporomandibular disorders, burning mouth syndrome, apical periodontitis, and peri-implant diseases. Each oral complication will be briefly introduced, followed by an assessment of the literature studying epidemiological associations with DM. We will also elaborate on pathogenic mechanisms that might explain associations between DM and oral complications. To do so, we aim to expand our perspective of DM by not only considering elevated blood glucose levels, but also including literature about the other important pathogenic mechanisms, such as insulin resistance, dyslipidemia, hypertension, and immune dysfunction.

Prevalence of root caries among elders living in residential homes of Bengaluru city, India

Background

Among the various oral ailments which have been observed in elderly, root caries is a significant one. Tooth loss is chief oral health-related negative variable to the quality of life in elderly and root caries is the major cause of tooth loss in them. It has been reported about a third of older population bears most of the root caries burden, so the present study aimed to assess the prevalence of root caries among older individuals residing in residential homes of Bengaluru city India.

Material and Methods

Elderly individuals aged 60 and above, residing in residential homes of Bangalore city, were included in the study. The study participants filled a questionnaire regarding their demographic details and oral health habits. Root surface caries was recorded according to criteria described by Banting et al. and root caries was expressed in terms of the root caries index (RCI). The statistical analysis was performed using descriptive statistics and chi-square test. P < 0.05 was considered as statistically significant.

Results

The prevalence of root caries was 46.4%. The root caries index was 15%. Statistically significant differences (P < 0.05) observed across gender, marital status, diet, socio-economic status, medication, method of cleaning and frequency of cleaning and were identified as significant predictors of root caries.

Conclusions

The prevalence of root caries among institutionalized older people was high. Oral health policies and preventive measures are needed focusing on the special needs of this neglected and socioeconomically deprived population to improve their quality of life.

Serum albumin levels and 10-year tooth loss in a 70-year-old population

Serum albumin levels are a practical marker of general health status in the elderly and have been used to determine the severity of underlying diseases and the risk for death. This longitudinal study evaluated the relationship between serum albumin concentrations and tooth loss over 10 years in elderly subjects, after controlling for confounding factors. A sample of 554 dentate subjects among enrolled subjects (n = 600) was involved in this planned longitudinal study with follow-up examinations after 5 and 10 years. At the 5-year follow-up, 373 (67·3%), subjects were available for re-examination. In addition, 331 (59·7%) were available at the 10-year follow-up. Multiple Poisson regression analysis was conducted to evaluate the relationship between the number of missing teeth over 5 or 10 years and serum albumin levels at baseline after adjusting for 10 variables: gender, serum markers levels at baseline, dental status, smoking habits and educational years and oral health behaviour. The number of missing teeth over 5 or 10 years was significantly negatively associated with serum albumin levels at baseline [incidence rate ratios (IRR) = 0·373, P < 0·0001 for 5 years; IRR = 0·570, P < 0·0001 for 10 years]. We conclude that elderly subjects with hypoalbuminemia are at high risk for 5- and 10-year tooth loss.

Successes, Challenges and Lessons Learned: Community-engaged research with South Carolina's Gullah population

Engaging communities is highly recommended in the conduct of health research among vulnerable populations. The strength of community-engaged research is well documented and is recognised as a useful approach for eliminating health disparities and improving health equity. In this article, five interdisciplinary teams from the Medical University of South Carolina present their involvement with community-engaged research with a unique population of Gullah African Americans residing in rural South Carolina. Their work has been integrated with the nine established principles of community-engaged research: establishing clear goals, becoming knowledgeable about the community, establishing relationships, developing community self-determination, partnering with the community, maintaining respect, mobilising community assets, releasing control, and maintaining community collaboration. In partnership with a Citizen Advisory Committee, developed at the inception of the first community-engaged research project, the academic researchers have been able to build on relationships and trust with this population to sustain partnerships and to meet major research objectives over a 20-year period. Challenges observed include structural inequality, organisational and cultural issues, and lack of resources for building sustainable research infrastructure. Lessons learned during this process include the necessity for clearly articulated and shared goals, knowledge about the community culture, and embedding the cultural context within research approaches.

Root caries and diabetes: risk assessing to improve oral and systemic health outcomes

This report reviews the current understanding of the relationship between diabetes and root caries, and investigates the evidence for dental chairside testing of gingival crevicular blood (GCB) glucose levels to assess risk for type 2 diabetes mellitus. Diabetes is linked with the progression of periodontal disease and a greater number of exposed root surfaces at risk for root caries. The rapidly increasing prevalence of type 2 diabetes coupled with a general trend towards retention of teeth means that the number of patients with increased risk for root caries is expanding significantly. Many patients with diabetes or abnormal blood glucose levels are unaware of their condition or that they are at increased risk for oral disease. Systemic blood glucose concentrations are comparable to those found in GCB and therefore may be a useful adjunctive clinical aid in determining appropriate care for patients and providing timely referrals to general medical practitioners. Use of GCB testing within the dental clinic is described. It is proposed that future studies be undertaken to provide clinicians with improved risk assessment strategies and to evaluate GCB glucose screening models.
