Clinicians’ view on the management of oral health in Parkinson’s disease patients: a qualitative study

Background: due to numerous motor and non-motor symptoms, dental treatment in patients with Parkinson’s Disease (PD) can be challenging. Knowledge regarding optimal management of oral health in PD patients is lacking. Aim: to gain a deeper understanding of the experiences of dentists regarding oral health care for PD patients in the Netherlands. Material and method: semi-structured interviews were conducted with (specialized) dentists working with PD patients. A thematic analysis was performed using a framework-based approach. Results: ten dentists were interviewed. They reported that dental care in PD patients requires 1) adaptation of timing and length of treatments and consultations, and 2) intensifying preventive measures. Dentists experienced the organization as bureaucratic and difficult. Moreover, differences between being institutionalized or living at home were present. Education and research are needed to improve PD patients’ oral health. The experience level and affinity for treating PD patients positively influences confidence levels of the practitioner. Finally, points of improvement were suggested. Conclusion: managing oral health in PD patients is challenging, and interdisciplinary collaboration is needed to overcome difficulties. Reducing the bureaucratic burden and improving knowledge could help and stimulate oral health care providers to treat PD patients more effectively and, consequently, improve their oral health

The effect of extrusion screw-speed on the water extractability and molecular weight distribution of arabinoxylans from defatted rice bran

Arabinoxylans (AXs) are major dietary fibre in cereals. Recently, AXs have attracted a great deal of attention because of their biological activities. These activities have been suggested to be related to the content of low molecular weight (Mw) AXs, in particular those with Mw below 32 kDa. Rice bran is a rich source of AXs. However, water extraction of AXs is difficult and often gives low yield. Extrusion processing has been used to increase the solubility of cereal dietary fibre. The aim of this research was to study the effect of extrusion screw-speeds (80 and 160) rpm on the extraction yield and Mw of water extractable AXs from rice bran. It was found that the extraction of AXs increased significantly with an increase in screw speed and was accompanied by a significant decrease in the Mw of AXs from extruded rice bran. The percentage of very low molecular weight AXs (0.79–1.58 kDa) significantly increased with increasing screw speed
