Oral health and chemotherapy act as cofactors in malnutrition in the elderly with other cancers than head and neck malignancies

The Role of Dental Oncology in Cancer Care: a Critical Component of Comprehensive Treatment, Education, and Interdisciplinary Collaboration- a Narrative Review

Dental oncology, a vital branch of special care dentistry, addresses the oral health needs of patients undergoing cancer treatment. This narrative review explores the critical role of dentists specializing in cancer care, known as "onco-dentists," in managing the unique oral complications caused by cancer therapies, including chemotherapy, radiation therapy, and surgery. These treatments often lead to a range of oral health issues, such as mucositis, xerostomia, dental caries, periodontal disease, and trismus, significantly impacting a patient's quality of life and potentially disrupting cancer care. By providing tailored preventive and therapeutic interventions, onco-dentists enhance treatment outcomes and improve overall patient well-being. Furthermore, their collaboration with oncologists and other healthcare professionals promotes integrated care plans that address both cancer treatment and oral health management, emphasizing the importance of a holistic approach to patient care. This review aims to highlight the multifaceted role of onco-dentists, the significance of interdisciplinary collaboration, and the necessity of proactive oral health management in comprehensive cancer care. Moreover, the review underscores the importance of education at multiple levels-integrating dental oncology into medical and dental curricula, raising public awareness, and providing patient education to empower individuals in managing their oral health during cancer treatment.

Age related impairments in ingestion from a large population based-sample

OBJECTIVES

Epidemiological data regarding the evolution of problems related to mastication and swallowing with age are lacking. This study aims to (i) describe changes in oral function with age, using data from a large French population, (ii) validate online, self-report uses of an ICF questionnaire in older persons, and (iii) assess whether impairment is related to avoidance of certain foods, xerostomia, body mass index (BMI) and oral health related quality of life (OHRQoL).

METHODS

Volunteers aged ≥18 years with internet access completed a series of questionnaires on sociodemographic, anthropometric and oral health characteristics (oral function, Xerostomia Index (XI), OHRQoL, reasons for avoidance of certain food). Oral function was assessed using items derived from the International Classification of Functioning (ICF). Five ICF items related to ingestion function and six items related to activities and participation were used. A validation study was undertaken to identify those with poor chewing ability and low salivary flow amongst older participants reporting impairment.

FINDINGS

39 597 individuals were included. The prevalence of individuals with impairment for ICF items related to ingestion function and oral activity (eating, drinking and speaking), and the percentage of participants with poor OHRQoL increased significantly with age (p < 0.001). Each ICF item was significantly associated with OHRQoL (p < 0.001), XI (p < 0.001), BMI (p < 0.001) and avoidance of certain food due to chewing or swallowing difficulties.

CONCLUSION

Overall, 21.5% and 13.5% of the study population had chewing and/or biting impairments respectively, which might affect food selection and consumption. These findings raise individual and population-based issues. Further studies are needed to assess whether impairment in oral function might increase frailty in older individuals, and also to compare data with those from other countries.

Dental Criteria Could Alert for Malnutrition Risk and Inappropriate Choice of Food Texture in Older Subjects with Dementia: An Analytical Cross-Sectional Study

Oral health indicators are usually collected to alert for the presence of infectious diseases, but the impact of poor oral health on the nutritional status of older people with dementia is often neglected. This study aims to explore the relationship between the number of posterior dental functional units (PFUs) and the anthropometric measure of malnutrition, the mid-upper arm circumference (MUAC), in older people with dementia while controlling for other variables, and to analyze whether the number of PFUs is considered when adjusting the texture of the food provided at mealtimes. A total of 103 individuals who were 70 years or older with dementia were recruited from seven institutions. Cognitive impairment was assessed using the Mini Mental State Examination. Data were collected from medical records (sociodemographic characteristics, presence of chronic diseases, prescribed medications, results of serum albumin level), as well as questionnaires (type of feeding routes, type of food texture, supplements intake, Activity of Daily Living index), clinical examinations (MUAC), and oral health parameters (PFUs, oral dryness, oral hygiene). MUAC was the dependent outcome variable. MUAC was associated with the number of PFUs (p = 0.032); participants with PFU ≤ 4 were 7.5 times more likely to have MUAC < 21 cm than others. Other associations were found between MUAC and albumin level (OR = 12.5; p = 0.001), modified food texture (OR = 4.2; p = 0.035), and length of institutional stay (OR = 5.2; p = 0.033); however, the type of oral feeding was not significantly related to the number of PFUs (p = 0.487) so there is an inadequate correlation between food texture and oral health status. Similar to MUAC, the number of PFUs could be an oral anthropometric criterion that is recorded during routine hygiene care to alert for the risk of malnutrition and the inappropriate choice of food texture in older individuals with dementia.

[Nutritional Risk Screening in head-and-neck cancer patients prior to oncological therapy]

OBJECTIVE

Head-and-neck cancer patients run a high risk of peri- or post-treatment malnutrition that can severely affect the therapy outcome. However, little is known about malnutrition under the pre-treatment condition. Therefore, this study aimed to provide a systematic description of the pre-treatment nutritional status and risk of malnutrition in this population.

MATERIAL AND METHODS

Before the onset of the oncological therapy, nutritional status of 102 head-and-neck cancer patients was assessed by body mass index (BMI), their risk of malnutrition by "Nutritional Risk Screening" (NRS). Tumour stage and site, patients' age and sex as well as oropharyngeal dysphagia were analysed as possible influence factors. The latter was quantified by the Flexible Endoscopic Evaluation of Swallowing (FEES).

RESULTS

According to BMI, malnutrition (undernutrition) was found in 6% of patients, a risk of malnutrition (NRS) in 27% of patients, and oropharyngeal dysphagia in 15%. In a linear regression, only oropharyngeal dysphagia was identified as a significant influence factor for the risk of malnutrition (β = 0.380/3.776; p < .001).

CONCLUSIONS

Pre-treatment risk of malnutrition was found in a quarter of head-and-neck cancer patients. For the early identification of this risk and for the introduction of measures that would help to avoid it, a pre-treatment examination of swallowing functions and a systematic malnutrition screening by means of NRS are recommended.

Oral and dental health status in patients undergoing neoadjuvant chemotherapy for locally advanced head and neck cancer

OBJECTIVE

A prospective, longitudinal assessment of oral and dental health status was done from baseline until treatment completion in patients scheduled to receive neoadjuvant chemotherapy (NACT) for locally advanced head and neck cancer (LAHNC).

STUDY DESIGN

One hundred fifty consecutive, treatment-naïve adult patients with biopsy-proven LAHNC scheduled to receive NACT were recruited. One hundred thirty-five patients completed all assessments at 3 designated time points: baseline (T0), midtreatment (T1), and posttreatment (T2). Variables assessed were: Oral Hygiene Index-Simplified (OHI-S) score; decayed, missing, or filled teeth (DMFT) score; mucositis grade; pain score; and grade of trismus.

RESULTS

Median OHI-S scores showed a statistically significant increase (higher the score, poorer the oral hygiene) when the patients were evaluated from baseline to completion of NACT (T1 vs. T2; T0 vs. T2; P < .001), which indicated a decrease in oral health. There was no change in median DMFT score (P = .32), but a significant change was seen in all-grade mucositis over time (P < .001). Median pain scores and trismus grades decreased significantly (P < .001) over time.

CONCLUSIONS

There was a decrease in oral health status without any change in dental health seen in patients undergoing NACT. Mucositis was initially noted as an aftermath of chemotherapy, which resolved with time.

Nutritional Status and Its Contributing Factors among Older Adults with Cancer Receiving Chemotherapy

The study aimed to assess nutritional status and its contributing factors among older adults with cancer receiving chemotherapy so, a descriptive study design was used. The study was conducted at Zagazig University Hospitals, Egypt. The study's sample was selected purposively which composed of 194 older adults. Nutritional status was measured by the Arabic version of the Mini-Nutritional Assessment (MNA). Contributing factors were identified by examining the relationship of nutritional status with demographic and clinical variables. Study results revealed that 33% of the older patients were malnourished and 51.5% were at risk for malnutrition. Statistically significant relations were found between nutritional status and advanced age, illiteracy, insufficient monthly income, comorbidities, cancer stage four at diagnosis, and receiving ≥4 chemotherapy cycles. High prevalence of malnutrition and many contributing factors were identified among older patients with cancer receiving chemotherapy. So, continuous malnutrition screening along chemotherapy courses with special concern for contributing factors assessed in this study is recommended.

Oral health care provided by nurses for hospitalized patients in Korea

OBJECTIVES

To investigate registered nurses' awareness and implementation of oral health care in patients who are hospitalized in general wards or intensive care units (ICUs) in South Korea.

METHODS

This research was performed as a descriptive survey of 149 nurses working in nine general hospitals with at least 100 beds in major Korean cities.

RESULTS

Approximately half (40.9%) of the survey respondents reported providing oral health care for hospitalized patients but that relevant protocols were not available at most hospitals or wards (89.5%). Nurses working in an ICU were significantly more likely to provide oral health care than those working in general wards (83.9% vs 15.1%; P < .001). Most respondents (83.2%) were aware of the importance of providing oral health care for hospitalized patients; however, the proportion considering that such care should be provided by dental hygienists was greater than that considering it should be provided by nurses (36.4% vs 26.0%; P < .001). Agreement that oral health care should be provided for hospitalized patients by dental hygienists was highest in nurses working in ICUs (53.3%; P < .001).

CONCLUSIONS

According to this survey, oral healthcare provision is generally low in hospitalized patients and differs between ICUs and general wards. Most respondents considered that dental hygienists should provide oral health care for hospitalized patients. There is an opportunity for nurses and dental hygienists to work collaboratively towards development of an evidence-based protocol for oral health care in hospitalized patients.

Relationship Among Denture Status, Remaining Teeth Number, and Malnutrition in Patients With Chronic Kidney Disease

The purpose of the present study was to evaluate the relationship among the denture status, number of remaining teeth, and malnutrition in patients with chronic kidney disease (CKD). Seventy-three patients (43 men/30 women) who required hemodialysis were included in the study. Weight and height, Kt/V, urea reduction ratio, midweek interdialytic weight gain, ultrafiltration volume, and erythropoietin dosage were determined for all patients. Laboratory measurements and predialysis blood samples for biomarkers were collected within the monthly routine tests. Dental examination focused on the denture status and total number of remaining teeth. Denture status were classified into two groups as prosthesis group (patients have prosthesis) and no prosthesis group (patients do not have any kind of prosthesis). And also, patients were assigned to one of four categories based on the number of remaining natural teeth: (i) edentulous, (ii) 1-7 teeth, (iii) 8-19 teeth, and (iv) >20 teeth. The data were statistically analyzed (a = 0.05). Body mass index values were increased in the prosthesis patients. Serum albumin levels of the CKD patients were under the reference value (3.8 g/dL) both in prosthesis and no prosthesis groups. Patients who have eight and more teeth showed higher serum albumin levels, and patients who had 1-7 teeth showed lower serum albumin levels in prosthesis group. CKD patients' nutritional habits were affected by denture status (having prosthesis or not). The number of the remaining teeth in prosthesis group affected the serum albumin levels of CKD patients.
