The Mediterranean diet (MD) is considered one of the healthiest dietary patterns. The aim of this study was to assess MD adherence in children and youth living in the Mediterranean region in Croatia and evaluate the differences in adherence to the MD among different educational stages. In total, 2722 individuals aged 2 to 24 years were enrolled in this study. Subjects were divided into different groups according to the Croatian educational system. Mediterranean Diet Quality Index (KIDMED) was used to assess adherence to the MD. In the total sample, the adherence to the MD was poor in 19.2%, average in 60.8%, and good in 20.1% of the study participants. The prevalence rate of poor adherence to the MD increased with higher educational stage, i.e., the highest prevalence rate of poor MD adherence was observed for college students (39.3%). Children having a higher number of snacks on days-off, those with lower physical activity, and not having breakfast together with a family are more likely to have poor MD adherence, while children having a higher number of snacks on working days are less likely to have a poor MD. The results of this study showed low adherence to the principles of the MD, confirming the need for improvement of adherence to the MD pattern in the studied population.

CD44 expressed in monocytes and lymphocytes seems to play a crucial role in gastrointestinal inflammation, such as the one occurring in the context of inflammatory bowel diseases. Differentially methylated genes are distinctly expressed across monocyte subpopulations related to the state of Crohn’s disease. Hence, the aim of this study was to detect CD44 expression in leukocyte subpopulations in relation to the type of IBD, therapy, and disease duration. Monocyte subpopulations CD14++CD16−, CD14++CD16++, and CD14+CD16+ as well as other leukocytes were analyzed for their CD44 expression using flow cytometry in 46 patients with IBD and 48 healthy controls. Patients with Crohn’s disease treated with non-biological therapy (NBT) exhibited a lower percentage of anti-inflammatory CD14+CD16++ monocytes, whereas NBT-treated patients with ulcerative colitis had lower expression of CD44 on CD14+CD44+ lymphocytes in comparison to controls, respectively. Conversely, patients with Crohn’s disease treated with biological therapy had a higher percentage of CD44+ granulocytes but lower expression of CD44 on anti-inflammatory monocytes compared to controls. Median fluorescence intensity (MFI) of CD44 on CD44+CD14+ lymphocytes was higher in ulcerative colitis patients treated with biological therapy compared to NBT. The percentage of classical CD14++CD16− monocytes was lower in the <9 years of IBD duration subgroup compared with the longer disease duration subgroup. The present study addresses the putative role of differentiation and regulation of leukocytes in tailoring IBD therapeutic regimes.

Objectives: To assess genotoxic and cytotoxic effect of commercially available toothpastes with the different whitening ingredients. Materials and Methods: In vivo assessment of cytotoxicity and genotoxicity of whitening toothpastes with different ingredients using a buccal micronucleus cytome assay (BMCyt assay) comprised 199 participants randomly divided into ten groups based on used whitening or control/conventional toothpaste. The exfoliated buccal mucosal cells were collected, stained and microscopically evaluated at baseline, 30 days and 60 days after the beginning of treatment, and 30 days after completing treatment: follow-up. Results: The genotoxic parameters showed no biologically significant changes in any of the observed period for the tested toothpastes, while cytotoxic parameters (number of cells with karyorrhexis and condensed chromatin) showed statistically significant difference (p>0.05) amongst evaluation periods for the three peroxide containing toothpaste. Conclusions: Peroxide containing whitening toothpastes present significant increase of cytotoxicity (numbers of karyorrhexis and condensed chromatin) during the application period only. Clinical Significance: Whitening toothpaste show no genotoxic effect, while peroxide containing whitening toothpastes may present significant increase of cytotoxicity (numbers of karyorrhexis and condensed chromatin) during application period. In clinical conditions, the obtained changes can’t be considered as significant. Trial registration: ClinicalTrials.gov: NCT04460755

CD44 expressed in monocytes and lymphocytes seems to play a crucial role in gastrointestinal inflammation, such as the one occurring in the context of inflammatory bowel diseases (IBD). Differentially methylated genes are distinctly expressed across monocyte subpopulations related to the state of Crohn's disease. Hence, the aim of this study was to detect CD44 expression at monocyte subpopulations, lymphocytes and granulocytes in relation to the type of IBD, therapy and disease duration. Monocyte subpopulations CD14++CD16−, CD14+CD16++ and CD14+CD16+, as well as other leukocytes, were analyzed for their CD44 expression using flow cytometry in 46 patients with IBD and 48 healthy controls. Patients with Crohn's disease treated with non-biological therapy (NBT) exhibited lower percentage of anti-inflammatory CD14+CD16++ monocytes, whereas NBT-treated patients with ulcerative colitis had lower expression of CD44 on CD14+CD44+ lymphocytes, in comparison to controls, respectively. Conversely, patients with Crohn's disease treated with biological therapy had higher percentage of CD44+ granulocytes, but lower expression of CD44 on anti-inflammatory monocytes compared to controls. Percentage of classical CD14++CD16- monocytes was lower in the <9 years of IBD duration subgroup, compared with the longer disease duration subgroup. The present study addresses the putative role of differentiation and regulation of monocyte and lymphocyte cells in tailoring IBD therapeutic regimes.
