Associations between Dentition Status and Nutritional Status in Community-Dwelling Older Adults.

BACKGROUND/OBJECTIVE: Older adults are at higher risk of malnutrition. The aim of this study was to explore associations between nutritional status and dentition status among older adults seeking care in a dental clinic. METHODS: This was a cross-sectional study of data from older adults (65-89 y) who received care at a northeastern US urban dental school clinic between June 2015 and June 2020 (N = 305). Clinical and demographic data were obtained from the electronic health record; nutritional status was determined using the Self-Mini Nutritional Assessment (Self-MNA), and odontograms and digital radiography were used to determine dental data. Adjusted multivariable models were used to explore associations between variables. RESULTS: The sample was 53.8% female with a median age of 72.0 y. The median Self-MNA score was 13, reflective of normal nutritional status; 29.5% were at risk of or had malnutrition. Median numbers of teeth and posterior and anterior occluding pairs of teeth (POP, AOP) were 18.0, 2.0, and 5.0, respectively. Those with normal nutritional status had significantly more teeth, POPs, and AOPs than those at risk of or with malnutrition (P = 0.015, P = 0.015, and P = 0.039, respectively). Every additional unit increase in the number of natural or restored teeth or POP was associated with significantly lower odds of being at risk of or with malnutrition (3% and 13%, respectively). Having functional dentition was associated with 46% lower odds of being at risk of or with malnutrition. CONCLUSION: This study demonstrated that older adults who had more teeth, better occlusion, and functional dentition were more likely to be of normal nutritional status than those who had less teeth, had poorer occlusion, and lacked functional dentition. Further research with larger, more diverse samples and varied measures of dentition are needed to better understand the associations between nutritional status and dentition status. KNOWLEDGE TRANSFER STATEMENT: The findings from this study suggest that older adults with fewer teeth and therefore less efficient occlusion are at higher risk for malnutrition than those with more teeth and better occlusion. Health care professionals should include screening for dentition and malnutrition as part of their routine practice to identify patients who may have tooth loss and be at risk of malnutrition and refer them accordingly for interventions to optimize oral health and nutritional status.

Tooth Loss and Nutritional Status in Older Adults: A Systematic Review and Meta-analysis.

BACKGROUND/OBJECTIVE: Older adults are at risk for tooth loss and compromised nutritional status. Our objective was to conduct a systematic review and meta-analysis to answer the following question: Among adults aged ≥60 y living in developed countries, what are the associations between tooth loss and nutritional status as assessed by a validated nutrition screening or assessment tool? METHODS: PRISMA guidelines were followed. PubMed, Scopus, CINAHL, Web of Science, and MEDLINE were searched for studies published in English between 2009 and 2019 that met inclusion criteria. Data extracted included study and participant characteristics, dentition, and nutritional status. Risk of bias was assessed with a modified Newcastle-Ottawa Scale. Random effects meta-analysis was used. RESULTS: Of the 588 unduplicated articles identified, 78 were reviewed in full text, and 7 met inclusion criteria. Six studies were combined for a meta-analysis, which revealed that individuals who were completely edentulous or who lacked functional dentition had a 21% increased likelihood of being at risk of malnutrition or being malnourished, as compared with those who were dentulous or had functionally adequate dentition (risk ratio, 1.21; 95% CI, 1.11 to 1.32; I2 = 70%). Whether the article statistically adjusted for medical history explained most of the heterogeneity in the pooled effect. CONCLUSIONS AND IMPLICATIONS: Findings suggest that older adults with tooth loss are at greater risk of malnutrition than those with functionally adequate dentition. Use of validated tools to assess risk of malnutrition in older adults with tooth loss is important to promote early intervention and referral to optimize nutrition and oral health status. Findings were limited by heterogeneity, risk of bias, and overall quality of the studies reviewed. Cohort studies that adjust for known confounders and use consistent approaches to assess tooth loss and nutritional status are needed. KNOWLEDGE TRANSFER STATEMENT: The results of this study suggest that older adults with tooth loss are at greater risk of malnutrition than those with functionally adequate dentition. Screening of this population for malnutrition by health care professionals, including dentists and dietitians, may result in corresponding referrals to optimize nutrition and oral health status. Further research is needed with consistent approaches to assess tooth loss and nutritional status.

The Eating Experience: Adaptive and Maladaptive Strategies of Older Adults with Tooth Loss.

OBJECTIVE: To explore the eating experience and eating-related quality of life (ERQOL) of community-dwelling older adults with tooth loss. METHOD: Nineteen older adults from the clinics of a northeast US dental school who met inclusion criteria (>65 y old, <20 teeth, and no dentures) composed the sample. For this mixed methods study, demographic characteristics, number and location of teeth, Mini Nutritional Assessment-Short Form score, and anthropometrics data were collected; semistructured interviews were conducted to collect in-depth information about the eating experience and ERQOL. Thematic analysis was completed with NVivo 12 software (QSR International). RESULTS: Participants' mean age was 71.3 y (SD = 5.2); 52.6% (n = 10) were women; 63.2% (n = 12) were Black or African American. The mean Mini Nutritional Assessment-Short Form score of 12.1 was reflective of normal nutrition status; 31.6% (n = 6) of patients were at risk for malnutrition or were malnourished. Fifteen percent (n = 3) were fully edentulous; 84.2% (n = 16) had 1 to 19 teeth (mean = 10.8, SD = 6.5). The 2 overarching themes identified were adaptive and maladaptive behavioral responses to tooth loss. Adaptive strategies included modification in food preparation and cooking methods, food texture selection, meal timing, and approaches to chewing. Maladaptive behaviors included food avoidance and limiting eating and smiling in front of others. Psychosocial factors, including finances, limited food choices and ERQOL, whereas the support of family and friends enhanced ERQOL according to participants. CONCLUSION: Older adults with tooth loss exhibit both adaptive and maladaptive behaviors that affect their eating experience, dietary intake, and ERQOL. While many expressed positive adaptive coping strategies, they also described maladaptive behaviors, including avoidance of healthy foods and limiting eating during social interactions, which may affect their nutritional status and overall health and well-being. Further research is needed to explore how duration and severity of tooth loss influence these behaviors and risk of malnutrition. Interprofessional approaches are needed to support positive adaptation and coping with tooth loss. KNOWLEDGE TRANSFER STATEMENT: The results of this study can be used by health professionals treating patients with tooth loss in an effort to improve their eating experience and eating-related quality of life. The findings provide data to support further studies and the need for evidence-based guidelines and educational materials to meet the unique needs of older adults with tooth loss.

Mirtazapine in progressive multifocal leukoencephalopathy associated with polycythemia vera.

Progressive multifocal leukoencephalopathy (PML) is a usually fatal cerebral white matter disease found in patients with human immunodeficiency virus infection and other immunocompromised states. We present the case of a 63-year-old woman with polycythemia vera who developed a progressive focal neurological deficit with white matter abnormalities on magnetic resonance images of the brain that was proved on biopsy to be PML. She was treated with the serotonin reuptake inhibitor mirtazapine and remains neurologically stable, with resolution of cerebral lesions, >2 years after diagnosis. We propose that mirtazapine should be investigated further for use in PML.
