Relationship Between Early Childhood Oral Health Impact Scale, Child's Dental Status and Parental Psychological Profiles

BACKGROUND

The aim of this study was to assess the influence of a child's dental status and parental psychological profiles on parental perception of their child's oral health.

MATERIALS

This study involved 164 parents of children under five years of age, who filled out the life quality assessment test regarding oral health (ECOHIS test), and Depression, Anxiety and Stress Scale (DASS) questionnaire. The child's oral status was also examined and recorded.

RESULTS

Results of the ECOHIS appeared to correlate positively with the number of active caries (R = 0.457; P <0.001). In addition, the ECOHIS showed a significant correlation with the DASS test results (R = 0.356; P <0.001 for depression, R = 0.247; P <0.001 for anxiety and R = 0.235; P <0.001 for the stress result).

CONCLUSION

The dental health of a child affects his/her quality of life and the parental quality of life including their psychological status.

Circulating YKL-40 in Philadelphia-negative myeloproliferative neoplasms

Objectives: Philadelphia-negative chronic myeloproliferative neoplasms (MPNs), essential thrombocythemia (ET), polycythemia vera (PV) and myelofibrosis (MF), are characterized by clonal myeloproliferation and a strong inflammatory atmosphere. YKL-40, expressed in granulocytes, macrophages, megakaryocytes and malignant cells, is an acute phase reactant with an important role in tissue remodeling and atherosclerotic inflammation. The aim of this study was to investigate serum YKL-40 levels in MPNs and to assess its clinical correlations. Methods: ELISA test was used to measure serum YKL-40 levels in 111 MPN patients and in 32 healthy controls. Results: Serum YKL-40 levels were higher in ET, post-ET MF, PV, post-PV MF and primary MF patients, when compared to healthy controls (p < 0.001). Higher serum YKL-40 levels were associated with parameters indicative of the increased inflammatory state (higher C-reactive protein, poor performance status, presence of constitutional symptoms and cardiovascular risk factors). Additionally, higher serum YKL-40 levels in MF patients were associated with blast phase disease, lower hemoglobin and higher Dynamic International Prognostic Scoring System score. In the multivariate Cox regression models, higher serum YKL-40 levels in ET and PV patients were independently associated with an increased risk of thrombosis (HR 4.64, p = 0.031) and impaired survival in MF patients (HR 4.31, p = 0.038). Conclusion: These results indicate that higher circulating YKL-40 levels in MPNs might have a pathophysiological role in disease progression and thrombosis development. Assessing circulating YKL-40 could help in identification of ET and PV patients at a high risk of future cardiovascular events and has a good potential for improving prognostication of MF patients.

Serum chitotriosidase: a circulating biomarker in polycythemia vera

OBJECTIVES

Serum chitotriosidase activity (CHIT1) is a biomarker of macrophage activation with an important role in inflammation-induced tissue remodeling and fibrosis. Macrophages have been described to play a crucial role in regulating pathological erythropoiesis in polycythemia vera (PV). The aim of this study was to evaluate CHIT1 in patients diagnosed with Philadelphia-negative myeloproliferative neoplasms (MPNs).

METHODS

Using fluorometric assay, we measured CHIT1 in 28 PV, 27 essential thrombocythemia (ET), 17 primary myelofibrosis (PMF), 19 patients with secondary myelofibrosis and in 25 healthy controls.

RESULTS

CHIT1 was significantly higher in PV (p < .001) and post-PV myelofibrosis (MF) transformation (post-PV MF) (p = .020), but not in ET (p = .080), post-ET MF transformation (p = .086), and PMF patients (p = .287), when compared to healthy controls. CHIT1 in PV was positively correlated with hemoglobin (p = .026), hematocrit (p = .012), absolute basophil count (p = .030) and the presence of reticulin fibrosis in the bone marrow (p = .023).

DISCUSSION

A positive correlation between CHIT1 and these distinct laboratory PV features might imply macrophages closely related to clonal erythropoiesis as cells of CHIT1 origin. In addition, a positive association between CHIT1 and reticulin fibrosis might indicate its potential role in PV progression.

CONCLUSION

CHIT1 might be considered as a circulating biomarker in PV. Additional studies are needed to clarify the role of CHIT1 in promoting disease progression and bone marrow fibrosis in PV.

Indole-3-carbinol in women with SLE: effect on estrogen metabolism and disease activity

Estrogen metabolism in women with SLE is weighted towards 16alpha-hydroxyestrone, an estrogenic compound that might fuel disease activity. Indole-3-carbinol (I3C) is a nutritional compound that can shift estrogen metabolism towards less estrogenic metabolites. However, the effects of I3C in women with SLE have not been studied. Open-label 1-week metabolic study of 375 mg/day I3C was carried out in women with SLE, followed by a 3-month observational period for disease activity. The primary outcome measure was the change in ratio of urinary 2:16alpha hydroxyestrone levels. Secondary measures included the SLE Disease Activity Index. Seventeen clinically premenopausal women fulfilling ACR criteria for probable/definite SLE (mean age 37.9 y, range 20-49 y, mean disease duration 4.3 y, range 0.5-15) completed the 1-week metabolic study; 12 took I3C for 3 months. The mean 2:16alpha hydroxyestrone ratio increased by 1.84 to 3.15 (P = 0.0001). Mean SLEDAI scores were 10.0 (baseline); 6.25 (3 months); and 8.8 (3 months after withdrawal; P = NS). Women with SLE can manifest a metabolic response to I3C and might benefit from its antiestrogenic effects. We did not observe any striking effects on SLE disease activity during the 3-month observational period.
