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.

A cross-sectional study on activity impairment in primary Sjogren's syndrome.

OBJECTIVE: The aim of this cross-sectional study was to show relations between activity impairment and salivary gland involvement for patient empowerment in primary Sjogren's syndrome (pSS). METHODS: In the study, 86 patients with pSS were included. The data were collected through clinical examinations and a questionnaire regarding Work Productivity and Activity Impairment (WPAI), EULAR Sjogren's syndrome patient-reported index (ESSPRI) and Oral Health Impact Profile-14 (OHIP-14). Relations were analysed by using mediation and moderation analyses. In simple mediation analysis, an independent variable (X) influences outcome variable (Y) through a mediator variable (M) whereas a moderator variable (W) affects the direction of the relationship between the dependent (Y) and independent variables (X). RESULTS: Increases in ESSPRI-Dryness score (X) (p = 0.0189) and OHIP-14 score (M) (p = 0.0004) were associated with the poor WPAI activity impairment score (Y) in the first mediation analysis. The WPAI activity impairment score was mediated by the elevated ESSPRI-Fatigue score (X) (p = 0.03641) and low U-SFR (M) (p = 0.0000) in the second mediation analysis. In addition, ESSPRI-Pain score (W) was the significant moderator for WPAI activity impairment (Y) in patients without hyposalivation in the moderation analysis (p = 0.0010). CONCLUSION: WPAI activity impairment was affected by both ESSPRI-Dryness with OHRQoL and ESSPRI-Fatigue with SFR in glandular involvement.

Do Patient Experiences Have Mediating Roles on Patient Loyalty?

The study aimed to evaluate the mediating roles of patient experiences on patient loyalty. The data were collected through an electronic questionnaire regarding feedback from 5732 patients received outpatient clinics. Patient loyalty was evaluated using the Net Promoter Score (NPS11) that patients were asked whether they would like to recommend the hospital to their relatives or friends. Patient experiences with physicians, nurses, and waiting times were also asked in the questionnaire. After preliminary analysis, mediation analyses were performed to evaluate direct and indirect causal effects among variables for NPS11. While patient experiences are used as possible mediators, Branch Groups in the first and Admission Time in the second model are independent variables. In the analyses, Surgical Medical Science (p = 0.019) and Day Shift (p = 0.000) have a direct mediating effect on NPS11. Nursing care experiences were found to be a mediator variable for NPS11 in both models (p = 0.000 for both). Patient loyalty was associated with Surgical Medical Science and Day Shift primarily whereas Nursing care experience had a mediating role.

The assessment of presenteeism and activity impairment in Behçet's syndrome and recurrent aphthous stomatitis: a multicentre study.

OBJECTIVE: To evaluate key factors for presenteeism and activity impairment in multinational patients with Behçet's syndrome (BS) and recurrent aphthous stomatitis (RAS). METHODS: In this cross-sectional study, 364 BS patients from Jordan, Brazil, the United Kingdom and Turkey and 143 RAS patients from the United Kingdom and Turkey were included. The Work Productivity Activity Impairment (WPAI) scale was used for presenteeism and activity impairment. Mediation analyses were performed to evaluate both direct and indirect causal effects. RESULTS: Presenteeism score was higher in active patients with genital ulcers and eye involvement as well as patients with comorbidities and current smokers than the others in BS (P < 0.05). In RAS, presenteeism score was elevated by oral ulcer activity in the direct path (P = 0.0073) and long disease duration as a mediator in the indirect path (P = 0.0191). Patients with active joint involvement had poor scores in absenteeism, presenteeism, overall impairment and activity impairment compared with those of inactive patients (P < 0.05). Using mediation analysis, the activity impairment score was directly mediated by joint activity (P = 0.0001) and indirectly mediated through oral ulcer-related pain in BS (P = 0.0309). CONCLUSION: In BS, presenteeism was associated with disease activity, presence of comorbidities and being a current smoker, whereas in RAS, presenteeism was associated with oral ulcer activity and increased length of the disease. Moreover, activity impairment was adversely affected by joint activity and oral ulcer related pain in BS. Patients need to be empowered by using appropriate treatment strategies in their working environment and daily life.

HADS-depression score is a mediator for illness perception and daily life impairment in Takayasu's arteritis.

INTRODUCTION/OBJECTIVES: The aim of this study was to evaluate the relationships among the disease activity, illness perception, daily life performance, anxiety and depression status as potential mediators in Takayasu's arteritis (TAK) patients. METHOD: In this cross-sectional study, 77 TAK patients were included. Data were collected by a clinical examination and a structured questionnaire regarding patient reported outcome measures (PROMs). Indian Takayasu's Arteritis Activity Score2010 (ITAS2010) was used to assess the disease activity (0: inactive vs ≥ 1: active). Illness Perception Questionnaire-Revise (IPQ-R), Work Productivity and Activity Impairment (WPAI) and Hospital Anxiety and Depression Scale (HADS) as PROMs were used to understand for the patient' perspective. After preliminary analysis, complex relationships among these variables were evaluated by mediation analyses in the study. RESULTS: WPAI-Daily impairment score, HADS-A and HADS-D scores as well as IPQ-R Consequence score were found be high in active TAK patients (p = 0.008; p = 0.001; p = 0.031; p = 0.001). HADS-D score was also correlated with WPAI-Daily impairment score and IPQ-R Consequence score (p < 0.05). In mediation analysis, IPQ-R Consequence score was directly mediated by disease activity (ITAS2010) (p = 0.0173) and indirectly mediated through HADS-D score (p = 0.0003). Similarly, HADS-D score was associated with poor WPAI-Daily impairment score in the mediation analysis in the indirect path (p = 0.0069). Disease activity (ITAS2010) also increased WPAI-Daily impairment score in direct path (p = 0.043). CONCLUSIONS: Active TAK patients perceived their illness more seriously and experienced more impairment in their daily life. Depression status as the mediator influenced them poorly. These interactions could give clues to improve PROMs in the clinical practice. Key Points •IIness perception, disease activity, mental status and daily life performance, assessed as patient-reported outcome measures, have a complex relationship in Takayasu's arteritis. •IPQ-R Consequence score, WPAI-Daily impairment score, HADS-Depression and HADS-Anxiety scores were found be high in active TAK patients. •In mediation analysis, IPQ-R Consequence score was directly mediated by disease activity and indirectly mediated through HADS-D score. Similarly, disease activity increased WPAI-Daily impairment score in direct and HADS-D in indirect paths.

Elevated serum TREM-1 is associated with periodontitis and disease activity in rheumatoid arthritis.

The triggering receptor expressed on myeloid cells 1 (TREM-1) and peptidoglycan recognition protein 1 (PGLYRP1) are involved in the propagation of inflammatory responses. This study investigated whether serum levels of TREM-1 and PGLYRP1 correlate with periodontitis in rheumatoid arthritis (RA) patients. A total of 154 non-smoking participants with RA (n = 55, F/M: 41/14), Behçet´s disease (BD, n = 41, F/M: 30/11) and healthy controls (HC, n = 58, F/M: 40/18) were recruited. Serum and saliva were collected, the 28-joint disease activity score (DAS-28) was calculated and dental/periodontal measurements were recorded. Serum TREM-1 and PGLYRP1 levels were measured by ELISA and salivary bacterial DNA counts by quantitative polymerase chain reaction. TREM-1 and PGLYRP1 levels were higher in RA (166.3 ± 94.3; 155.5 ± 226.9 pg/ml) than BD (102.3 ± 42.8; 52.5 ± 26.3 pg/ml) and HCs (89.8 ± 55.7; 67.4 ± 37.3 pg/ml) (p < 0.05). In RA, periodontitis was associated with increased TREM-1 and PGLYRP1 levels (p < 0.05), yet in patients under methotrexate TREM-1 levels were lower. TREM-1 correlated with C-reactive protein (CRP) levels, DAS-28 and erythrocyte sedimentation rate, whereas PGLYRP1 positively correlated with CRP. RA patients displayed 3.5-fold higher salivary bacterial DNA counts than HCs. Increased serum TREM-1 levels correlated with PGLYRP1, CRP and DAS-28-ESR in RA patients with periodontitis.

Moderation analysis exploring associations between age and mucocutaneous activity in Behçet's syndrome: A multicenter study from Turkey.

The aim of the present study was to examine the effects of age on mucocutaneous activity by using moderation analysis in Behçet's syndrome (BS). In this cross-sectional study, 887 BS patients (female : male, 481:406; mean age, 38.4 ± 10.9 years) followed in 13 tertiary centers in Turkey were included. Mucocutaneous activity was evaluated by using the Mucocutaneous Index (MI) according to sex and disease course. Moderation analysis was performed to test the effect of age on mucocutaneous activity. A moderator variable is a third variable and affects the relationship between independent and outcome variables. Age was chosen as a potential moderator variable (interaction effect), MI score as the outcome variable and sex as an independent variable in the analysis. The moderation analysis tested the effects of age in three steps: whole BS patient group, patients without systemic involvement and those with systemic involvement. The moderation model was only significant in BS patients with systemic involvement (P = 0.0351), and a significant relationship was observed between female sex and MI score (P = 0.0156). In addition, the interaction plot showed that female patients had increased MI scores compared with male patients, especially in the 28-year-old age group (P = 0.0067). Moreover, major organ involvement was newly diagnosed in the majority of these young female BS patients. Our results suggest that the relationship between sex and mucocutaneous activity was moderated by age in the systemic involvement group. Also, increased mucocutaneous activity may be associated with new major organ involvement in young female BS patients with systemic involvement.

Readiness for Health Information Technology is Associated to Information Security in Healthcare Institutions.

BACKGROUND: Health information technologies (HITs) present numerous opportunities for the improvement and transformation of healthcare, which include reducing human errors, improving clinical outcomes, facilitating care coordination, improving efficiency of practice and tracking data over time. HITs involve various technologies that range from simple charting, to a more advanced decision support and integration with medical technology. OBJECTIVE: The aims of this study were to examine the readiness for the implementation of health information technologies (HITs) among medical and administrative staff as well as to evaluate the effects of information security status on the readiness. METHODS: In this cross-sectional study, 236 medical employees (F/M: 192/44; mean age: 34±7.43 years) and 139 administrative employees (F/M: 93/46, mean age: 36±7.64 years) from 15 public health institutions in Kocaeli, Marmara Region were included. The data were collected via a structured questionnaire regarding opinions about information security and privacy, use of information technologies and the Organizational Information Technology Innovation Readiness Scale (OITIRS). After an explanatory factor analysis was performed for the scale, two subgroups regarding Organizational Readiness and Technological Readiness were obtained. Binary logistic regression analyses were performed to evaluate related factors for these subgroups of OITIRS. RESULTS: According to binary logistic regression analysis, establishing of a password management system was found to be a crucial factor for both organizational and technological readiness among medical and administrative employees in health institutions (p<0.05). The enhancement of collaboration among staff by implementing information technologies was a critical factor for the medical staff; whereas, the attitude of employees to ensure information security was an important factor for the administrative employees in both subgroups (p<0.05). CONCLUSION: Both medical and administrative unit employees stated that establishing a password management system that determines the frequency of changing passwords in the organization would affect both organizational and technical readiness in healthcare institutions.

Predictive factors for work-day loss in Behçet's syndrome: A multi-center study.

OBJECTIVE: The aim of this multi-center study was to assess predictive factors for work-day loss as an indirect cost element in Behçet's syndrome (BS). METHODS: In this cross-sectional, multi-center study, 834 BS patients (F/M: 441/393, age mean: 38.4 ± 10.9 years) were included. Data were collected by a questionnaire regarding treatment protocols, disease duration, smoking pattern, frequency of medical visits during the previous year and self-reported work-day loss during the previous year. RESULTS: Work-day loss was observed in 16.2% of patients (M/F: 103/32). The percentages of being a smoker (81.8%), using immunosuppressive (IS) medications (82%), and having disease duration <5 years (74%) were higher in male patients with work-day loss (P < .05). The majority of males (90.9%) had more than four clinic visits during the previous year. Moreover, the mean work-day loss (30.8 ± 57.7 days) was higher in patients with vascular involvement (56.1 ± 85.9) than those without (26.4 ± 50.6 days) (P = .046). In addition, increased frequency of ocular involvement (25.9%) was also observed in patients with work-day loss compared to others (8.6%) (P = .059). CONCLUSION: Work-day loss was associated with both vascular and ocular involvement. Close associations were observed among male gender, early period of the disease, frequent medical visits, being a smoker and treatment with IS medications in patients with work-day loss.

Oral ulcer activity assessment with the composite index according to different treatment modalities in Behçet's syndrome: a multicentre study.

OBJECTIVES: The aim of this multicentre study was to understand patients' needs and to evaluate the oral ulcer activity with the Composite Index (CI), according to different treatment modalities in Behçet's syndrome (BS). METHODS: BS patients (n=834) from 12 centres participated in this cross-sectional study. Oral ulcer activity (active vs. inactive) and the CI (0: inactive vs. 1-10 points: active) were evaluated during the previous month. The effects of treatment protocols [non-immunosuppressive: non-IS vs. immunosuppressive: (ISs)], severity (mild vs. severe), disease duration (<5 years vs. ≥5 years) and smoking pattern (non-smoker vs. current smoker) were analysed for oral ulcer activity. RESULTS: Oral ulcer activity was observed in 65.1% of the group (n=543). In both genders, the activity was higher in mild disease course with non-IS treatment group compared to severe course with ISs (p<0.05). As a resistant group, patients with mild disease course whose mucocutaneous symptoms were unresponsive to non-IS medications were treated with ISs in a limited period and achieved the highest CI scores in females. Oral ulcer activity and poor CI score were associated with disease duration less than 5 years compared to others in male patients (p<0.05). CONCLUSIONS: Oral ulcer activity pattern is affected by both the combination of disease course, treatment protocols and disease duration. CI scores reflected the oral clinical activity and CI might be a candidate scale to evaluate the efficacy of treatments during the follow-up of oral ulcer activity in BS.

An Assessment of Health Information Systems Through the Perspective of Computer Engineering Students and Medical Students.

INTRODUCTION: Computer Engineering Students (CES) and Medical Students (MS) will actively participate in the management of health information system in the future. AIM: The aim of the study was to evaluate the views of CES and MS about the patient privacy and security of health information systems. METHODS: The participants of this cross-sectional study were the 3rd and 4th year CES of Marmara University, (n=163, F/M:71/92) and the 5th and 6th year MS of Marmara University (n=65, F/M:38/27). The data were collected via questionnaire comprising questions and statements about patient information security and confidentiality. Responses were prepared on the basis of 5 Point Likert Scale. RESULTS: During the assessment of the questionnaires, it was observed that the statement "Health records should be accessible to the other health workers besides the physician" discomforted more CES (93,3%) than MS (78,5%) (p=0.003). A similar proportion was observed about "On-line communication with the physician" more CES (87,1%) prefer to communicate with the physician via electronic media than do the MS (66,2%) (p=0.001). Another significant point to be noted about the questionnaire results was that slightly more CES (40,5%) favor restrictions on the accessibility of "personal correspondance information" than MS (35,4%) (p>0.05). CONCLUSION: In the future, CES, who will be both internal and external stakeholders of the multi-disciplinary structure of healthcare management, thought that problems regarding security and privacy may occur. Therefore, the relation between health information system and the occupational education and training of CES and MS are extremely important through the perspective in healthcare management.

Oral health is a mediator for disease severity in patients with Behçet's disease: A multiple mediation analysis study.

OBJECTIVES: The aim of the study was to examine whether oral health as an infection focus could mediate disease course in patients with Behçet's disease (BD). METHODS: In the study, oral health of 194 BD patients was examined at baseline and follow-up periods. The reasons for last dental visits were recorded as tooth extraction or regular control visits/planned treatments at the end of follow-up period. The Behçet's disease severity score was calculated with higher scores indicating a more severe course. Mediation analysis was carried out to assess the effects of oral health on disease severity score at follow-up period in the study. RESULTS: Dental and periodontal indices were found to be higher at follow-up visit compared to those of baseline (P < 0.05). Disease severity score was found to be higher in males (5.3 ± 2.4) compared to females (4.4 ±2.5) in the whole group (P = 0.005). Moreover, patients having tooth extraction at their last dental visit and patients with dental caries had a more severe disease course (5.4 ± 2.4; 5.5 ± 2.5) compared to others (4.2 ± 2.3; 4.4 ± 2.4; P < 0.0001). In multiple mediation analysis, disease severity score was a dependent variable and was directly mediated by male gender (B = -0.8822, P = 0.0145) and indirectly mediated through the presence of dental caries (B = 0.9509 P = 0.0110) and need of tooth extraction (B = 0.8758, P = 0.0128). CONCLUSION: Both presence of dental caries and need of tooth extraction were observed to be effective mediators for a more severe disease course in BD. Therefore, better oral health should be aimed to eliminate microbial factors, which are a part of pathogenic processes.
