Does decision tree analysis predict oral ulcer activity-related factors in patients with Behçet's syndrome?

OBJECTIVES: The study aimed to identify the interactions among treatment protocols and oral ulcer activity related factors in patients with Behçet's syndrome (BS) using the Classification and Regression Tree (CART) algorithm. METHODS: In this cross-sectional study, 979 patients with BS were included from16 centres in Turkey, Jordan, Brazil and the United Kingdom. In the CART algorithm, activities of oral ulcer (active vs. inactive), genital ulcer (active vs. inactive), cutaneous involvement (active vs. inactive), musculoskeletal involvement (active vs. inactive), gender (male vs. female), disease severity (mucocutaneous and musculoskeletal involvement vs. major organ involvement), smoking habits (current smoker vs. non-smoker), tooth brushing habits (irregular vs. regular), were input variables. The treatment protocols regarding immunosuppressive (IS) or non-IS medications were the target variable used to split from parent nodes to purer child nodes in the study. RESULTS: In mucocutaneous and musculoskeletal involvement (n=538), the ratio of IS use was higher in patients with irregular toothbrushing (ITB) habits (27.1%) than in patients with regular toothbrushing (RTB) habits (14.2%) in oral ulcer activity. In major organ involvement (n=441), male patients with ITB habits were more likely treated with IS medications compared to those with RTB habits (91.6% vs. 77.6%, respectively). CONCLUSIONS: Male BS patients on IS who have major organ involvement and oral ulcer activity with mucocutaneous and musculoskeletal involvement have irregular toothbrushing habits. Improved oral hygiene practices should be considered to be an integral part for implementing patient empowerment strategies for BS.

The impact of the COVID-19 pandemic on patients with Behçet's syndrome within the framework of Maslow's hierarchy of needs: implications for patient empowerment in national or global emergencies.

OBJECTIVES: The aim of this online survey was to assess the impact of the COVID-19 pandemic on patients with Behçet's syndrome (BS) using Maslow's hierarchy of needs. METHODS: Sixty-eight BS patients from the UK completed an online questionnaire that covered three components of Maslow's hierarchy of needs regarding Physiological needs (sleep, food, mobility), Safety needs (employment, health), Social needs (relationships), personal precautions and main concerns regarding COVID-19. RESULTS: The patients received a letter from the NHS (66.2%) advising shielding. Health concerns were addressed using Tele-medicine by telephone consultations and e-mails to access BS specialists during lockdown (44.1%; 27.9%). In addition, patients also obtained information through official government and Behçet corporate health web pages related to Behçet's disease for self-empowerment. During lockdown, their weekly working hours were reduced (26.65±13.86 vs. 20.79±17.94) (p=0.017) and the employment rate was decreased (32.6% vs. 26.7%) in comparison to pre-lockdown. Moreover, the reduction in frequency of exercise per week (4.39±1.94 vs. 3.71±2.26) and healthy food consumption (73.5 % vs. 47.1%) per week were also reported (p=0.007; p=0.001, respectively). Furthermore, patients experienced sleeping less (54.4%) and feeling lonely (66.1%). CONCLUSIONS: Using Maslow's hierarchy of needs provided a framework for reviewing the quality of basic needs in patients' life during lockdown. These needs are required for healthy social lives and the deprivation should be considered while considering healthcare planning. Since lockdown appeared to have a negative influence on patients' lives and disease management in the framework of patient-centred, the empowerment of patients gained importance at this point.
