Xerostomia: a silent burden for people receiving palliative care - a qualitative descriptive study

BACKGROUND

The prevalence of dry mouth in the palliative care population is well documented and increases due to polypharmacy, radiotherapy and systemic conditions. Saliva as a lubricant for the mouth and throat has implications for swallowing, chewing, and speech. The literature about the experience of xerostomia (perceived feeling of dry mouth) in palliative care is scarce. Clinical evidence suggests that xerostomia has a negative impact on people's comfort, however, no recent studies explored this impact in detail. This new knowledge is paramount to adhere to the principles of palliative care.

AIMS

To evaluate the impact of xerostomia on the lives of people receiving palliative care with particular reference to eating and speaking.  DESIGN: A qualitative descriptive study (interview design). Thematic analysis was used for data analysis.

SETTING

A single specialist palliative care centre in Ireland.

RESULTS

The majority of participants (35/40) had cancer. Xerostomia was reported to have multiple physical, psychological, and daily life consequences. Participants provided insights into the impact of xerostomia on sleeping, eating, talking, denture wearing, and they described in detail their intra-oral sensations associated with xerostomia. The negative effect of xerostomia on speech was reported as the most significant to participants.

CONCLUSION

Xerostomia has a profound impact on the daily lives of people receiving palliative care, including physical and psychological consequences. Speaking is often affected, which can impede the person's ability to communicate. There needs to be increased awareness of the impact of xerostomia and more research is required to understand how best to manage xerostomia in a palliative care setting.

Can the chokeberry juice be used as additional therapy for burning mouth syndrome in menopausal women?

The researchers' aims were to evaluate the effects of chokeberry juice in the treatment of burning mouth syndrome (BMS) and oral discomfort in menopausal women. The following validated scales and questionnaires were used before and after treatment: questionnaire used for selection of research participants with xerostomia, the xerostomia inventory, Visual Analogue Scale (VAS), localization of pain before and after treatment, short-form McGill pain questionnaire. There was statistically significant decrease in number of research participants who felt pain after therapeutic procedure (p < 0.05). Chokeberry juice, as additional therapy for BMS, reduced intensity of characteristic types of pain sensations and oral dryness feeling.

Probiotics alter biofilm formation and the transcription of Porphyromonas gingivalis virulence-associated genes

Background and Objective

The potential of probiotics on the prevention and control of periodontitis and other chronic inflammatory conditions has been suggested. Lactobacillus and Bifidobacterium species influence P. gingivalis interaction with gingival epithelial cells (GECs) but may not act in a unique way. In order to select the most appropriate probiotic against P. gingivalis, we aimed to evaluate the effect of several strains on Porphyromonas gingivalis biofilm formation and transcription virulence-associated factors (PgVAFs).

Methods

Cell-free pH neutralized supernatants (CFS) and living Lactobacillus spp. and Bifidobacterium spp. were tested against P. gingivalis ATCC 33277 and W83, in mono- and multi-species (with Streptococcus oralis and S. gordonii) biofilms. Relative transcription of P. gingivalis genes (fimA, mfa1, kgp, rgp, ftsH and luxS) was determined in biofilms and under GECs co-infection.

Results

Probiotics CFS reduced P. gingivalis ATCC 33277 levels in mono-species biofilms and living probiotics reduced P. gingivalis abundance in multi-species biofilms. L. acidophilus LA5 down-regulated transcription of most PgVAFs in biofilms and GECs.

Conclusions

Probiotics affect P. gingivalis biofilm formation by down-regulating overall PgVAFs with the most pronounced effect observed for L. acidophilus LA5.

Exercise, Immunity, and Illness

It is generally accepted that moderate amounts of exercise improve immune system functions and hence reduce the risk of infection whereas athletes engaged in regular prolonged and/or intensive training have a higher than “normal” incidence of minor infections, especially of the upper respiratory tract (URT, e.g., common cold and influenza). This is likely related to regular acute (and possibly chronic) periods of exercise-induced changes in immune function. URT infections can compromise performance directly if suffered shortly before or during competition or indirectly if suffered at other times via effects on training and/or physiological adaptations. This chapter covers the effects of exercise (acute and chronic), both positive and negative, on immune function and consequent infection risk, and considers the current state-of-the-art for monitoring and assessing this in athletes.

Examination of intensive care unit patients' oral health

BACKGROUND

Oral health problems are common complications that most intensive care unit patients experience. There are many factors that affect oral health negatively and nurses have important responsibilities in this regard.

AIM

The aim of this study was assessment of the intensive care unit patients' oral health and risk factors.

METHODS

This study was planned as a descriptive study and conducted between December 2015 and June 2016, with 202 patients in 20 intensive care units of 6 hospitals in Turkey. Data were collected via Data Collection Form and Bedside Oral Exam guide. Oral health assessment of patients was made using a source of light and a tongue depressor.

RESULTS

We observed a significant difference in score of the Bedside Oral Exam guide by age, consciousness, type of respiration and feeding, the frequency of oral health, the total number of drugs, and technique of oral care (P < 0.05). None of the intensive care units were using the oral assessment guide.

CONCLUSION

The result of this study shows that there are various risk factors that adversely affect the oral health of intensive care unit patients. Nurses should undertake assessments on the basis of oral care protocols for patients at risk and carry out evidence-based individualized oral care applications.
