Oral symptoms in dying nursing home patients. Results from the prospective REDIC study.

BACKGROUND: The mouth is a central organ for communication and fluid intake, also for dying nursing home patients. This study describes the prevalence and severity of oral symptoms from nursing home admission until the day of perceived dying and the day of death. METHODS: A prospective, longitudinal cohort study including 696 patients who were admitted to 47 Norwegian nursing homes in 35 municipalities. During the first year of their stay, 189 died (27%), of whom 82 participants were assessed on the day they were perceived as dying and 134 on the day of death. Mouth care, nutrition, and bedsores were assessed with the Residents' Assessment Instrument for nursing homes (RAI-NH) and palliative care (RAI-PC). Pain intensity was assessed with the Mobilization-Observation-Behaviour-Intensity-Dementia-2 Pain Scale (MOBID-2). RESULTS: The proportion of patients with ≥ 6 oral symptoms increased from 16% when perceived as dying to 20% on the day of death (P = 0.001). On the day of death, xerostomia (66%), dysphagia (59%), and mastication problems (50%) were the most frequently observed oral symptoms. Only 16% received mouth care every hour and 12% were in pain during this procedure. Compared to people without dementia, those with a diagnosis of dementia at admission (N = 112, 86%) had xerostomia and mastication problems more frequently (50% vs. 73%; 32% vs. 56% (P = 0.038), respectively) on the day of death. CONCLUSIONS: The high extent of oral symptoms such as xerostomia, dysphagia, and mastication problems underline the need for systematic assessment and improved oral palliative care for dying nursing home patients with dementia.

Prevention of caries and obesity in children with immigrant background in Norway- a study protocol for a cluster randomized controlled trial.

BACKGROUND: Immigrants are known to experience greater socioeconomic stress and poorer well-being and to suffer more from lifestyle- and diet-related disorders than native populations. There is also evidence that children of immigrant parents are at greater risk of diverse health problems than their host country cohorts. The aim of this study is to apply and evaluate the efficacy of an early life intervention program among parents/children with immigrant background to prevent childhood caries and obesity, thereby improving the children's general health, oral health, and quality of life. METHODS: This is a study protocol for a cluster randomized controlled intervention follow-up study. In phase I of the study, the primary care health centers in the municipality of Bergen, Norway were randomly allocated to intervention or control groups. The intervention was carried out using the motivational interviewing technique and the common risk factor approach. The intervention group received guidance on diet/oral hygiene and the control group received standard care information. Parental knowledge and children at age 3 and 5 years old will be assessed in a prospective phase II follow-up study compared to native Norwegian controls. The primary outcome will be evaluation of change on parental oral health related knowledge and attitudes. The secondary outcome will assess the impact of the intervention on children's caries -, body mass index- and oral health related quality of life. DISCUSSION: Collaboration between dental public health and primary health care personnel on the common risk approach motivational intervention offers opportunities to address key dietary behaviors that may prevent obesity and dental caries. Providing sustainable preventive measures decreases the burden of diseases and consequently reduces health inequalities, particularly among at-risk children. TRIAL REGISTRATION: The study is registered as a clinical trial (ClinicalTrials.gov Identifier: NCT05758454: 7 March 2023). Ethical approval has already been granted by the Regional Ethical Committee (REK) (2015/ 27,639 /REK vest) and Sikt - Norwegian Agency for Shared Services in Education and Research (Reference number 778825).

An updated review of the effects of eicosapentaenoic acid- and docosahexaenoic acid-derived resolvins on bone preservation.

Resolvins are biosynthesized from omega-3 eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) in vivo by means of enzymatic activities, and these factors can attenuate inflammation and promote tissue regeneration. Inflammatory bone disorders can lead to bone loss and thereby be harmful to human health. The link between bone preservation and resolvins has been discussed in some experimental studies. Significant evidence has shown that resolvins benefit bone health and bone preservation by promoting the resolution of inflammation and directly regulating osteoclasts and osteoblasts. Therefore, this review highlights the role and beneficial impact of resolvins derived from EPA and DHA on inflammatory bone disorders, such as rheumatoid arthritis and periodontitis. In addition, the mechanisms by which resolvins exert their beneficial effects on bone preservation have also been summarized based on the available literature.

Impact of Resolvin D1 on the inflammatory phenotype of periodontal ligament cell response to hypoxia.

OBJECTIVE: Periodontal ligament cells (PDLCs) are critical for wound healing and regenerative capacity of periodontal diseases. Within an inflammatory periodontal pocket, a hypoxic environment can aggravate periodontal inflammation, where PDLCs response to the inflammation would change. Resolvin D1 (RvD1) is an endogenous lipid mediator, which can impact intracellular inflammatory pathways of periodontal/oral cells and periodontal regeneration. It is not clear how hypoxia and RvD1 impact the inflammatory responses of pro-inflammatory PDLCs phenotype. Therefore, this study aimed to test hypoxia could induce changes in pro-inflammatory phenotype of PDLCs and RvD1 could reverse it. METHODS: Human PDLCs were cultured from periodontal tissues from eight healthy individuals and were characterized by immunofluorescence staining of vimentin and cytokeratin. Cell viability was examined by Methyl-thiazolyl-tetrazolium (MTT) assay. To examine the effects of hypoxia and RvD1 on the inflammatory responses of pro-inflammatory PDLCs phenotype, protein levels and gene expressions of inflammatory cytokines and signal transduction molecules were measured by enzyme-linked immunosorbent assay (ELISA), western blotting (WB), and real-time quantitative reverse transcription PCR (real-time qRT-PCR). Alizarin red S staining and real-time qRT-PCR were employed to study the effects of hypoxia and RvD1 on the osteogenic differentiation of pro-inflammatory PDLCs phenotype. RESULTS: It was found that hypoxia increases the expression of inflammatory factors at the gene level (p < .05). RvD1 reduced the expression of IL-1ß (p < .05) in PDLCs under hypoxia both at the protein and RNA levels. There were increases in the expression of p38 mitogen-activated protein kinase (p38 MAPK, p < .01) and protein kinase B (Akt, p < .05) in response to RvD1. Also, a significantly higher density of calcified nodules was observed after treatment with RvD1 for 21 days under hypoxia. CONCLUSION: Our results indicate that hypoxia up-regulated the inflammatory level of PDLCs. RvD1 can reduce under-hypoxia-induced pro-inflammatory cytokines in the inflammatory phenotype of PDLCs. Moreover, RvD1 promotes the calcium nodules in PDLCs, possibly by affecting the p38 MAPK signaling pathway through Akt and HIF-1α.

Regional variations in caries experience, predictors, and follow-up among children and adolescents in Western Norway.

OBJECTIVE: To identify regional differences in, and determinants of dental caries among children in western Norway. MATERIAL AND METHODS: We studied dental caries in 705 children aged 12 years and 18 years living in the southern region (n = 403) and other parts of Hordaland County (n = 302) in Norway. Information on oral hygiene, fluoride intake, and sugar consumption was collected using questionnaires. We also collected information from the Public Dental Service (PDS) on the history of decayed, missing, or filled teeth; professional fluoride application; recall and regular check-up intervals and treatment visits. Residence (southern region versus the rest of Hordaland, the reference) was the independent variable. We analysed regional differences in (i) caries prevalence and severity, (ii) potential contributors to caries, and (iii) procedures and routines in PDS. RESULTS: Caries prevalence and severity were higher in the southern region (67% and 24%, respectively). Self-reported brushing habits, fluoride use, and sugar consumption patterns were similar between regions. We observed more frequent application of professional fluoride (incidence rate ratio [IRR] = 3.05, 95% CI: 1.99-4.66], fewer check-ups [IRR = 0.88, 95% CI: 0.81-0.95], and fewer treatment visits [IRR = 0.77, 95% CI: 0.60-0.98] among participants in the southern region, compared to the rest of Hordaland. The recall intervals in the southern region were 10% longer among 12-year-olds and 10% shorter among 18-year-olds, compared to their respective counterparts in Hordaland. CONCLUSIONS: The observed regional gradients in caries experience mirrored regional differences in dental routines and procedures. Caries-related risk behaviours did not explain the observed differences in caries experience.

Norwegian Orthodontists' Experience and Challenges With Treatment of Patients With Cleft Lip and Palate.

BACKGROUND: Patients born with cleft lip and/or palate (CL/P) have orthodontic treatment challenges due to maxilla deficiency, malocclusions, and dental abnormalities. In Norway, orthodontic treatment is done by centralized CL/P teams. Due to traveling restrictions, this treatment might be done locally in the future. The experience of Norwegian community orthodontists in managing such patients has not been investigated previously. OBJECTIVE: To assess Norwegian orthodontists' management of patients with CL/P and need for further education. MATERIAL AND METHODS: All orthodontists in Norway were sent a questionnaire about their experience, challenges, and knowledge and asked about their need of further theoretical education and clinical training in the management of patients with CL/P. RESULTS: Norwegian orthodontists' standard of knowledge of CL/P treatment is adequate. However, few respondents have treated a high number of cleft patients. Eighty-six percent of the participants believed that treating CL/P patients involves challenges, such as time-consuming treatment and technical difficulties. Increased perceived need for more education was revealed among participants stated unpreparedness during education (4 folds), encountered challenges, and lack of knowledge (almost 3 folds). CONCLUSIONS: The study revealed that community orthodontists in Norway lack experience and acknowledged the challenges in treating patients with CL/P. Most of the respondents perceived a need for additional education and clinical training to treat CL/P patients competently. The findings suggested more focus on patients with CL/P management in the curricula and more collaboration between centralized CL/P teams and community orthodontists.

Host biomarkers for monitoring therapeutic response in extrapulmonary tuberculosis.

PURPOSE: The aim of this study was to explore the utility of inflammatory biomarkers in the peripheral blood to predict response to treatment in extrapulmonary tuberculosis (EPTB). METHODS: A Luminex xMAP-based multiplex immunoassay was used to measure 40 inflammatory biomarkers in un-stimulated plasma of 91 EPTB patients (48 lymphadenitis, and 43 pleuritis) before and at 2 and 6 months of treatment. RESULTS: Overall a significant change was observed in 28 inflammatory biomarkers with treatment in EPTB patients. However, MIG/CXCL9, IP-10/CXCL10, and CCL23 decreased in all patients' groups with successful treatment at both time points. At 2 months, 29/64 (45%) patients responded partially while 35/64 (55%) showed complete regress. Among good responders, a higher number of biomarkers (16/40) reduced significantly as compared to partial responders (1/40). Almost half (14/29) of partial responders required longer treatment than 6 months to achieve satisfactory response. The levels of MIG, IP-10, MIF, CCL22 and CCL23 reduced significantly among 80, 74, 60, 71, 51% good responders, as compared to 52, 52, 52, 59, 52% partial responders, respectively. A biosignature, defined by a significant decrease in any one of these five biomarkers, corresponded with satisfactory response to treatment in 97% patients at 2 month and 99% patients at 6 months of treatment. CONCLUSION: Change in inflammatory biomarkers correlates with treatment success. A five biomarker biosignature (MIG, IP-10, MIF, CCL22 and CCL23) could be used as an indicator of treatment success.

Attitudes toward brushing children's teeth-A study among parents with immigrant status in Norway.

BACKGROUND: Early childhood caries (ECC) is a common chronic childhood disease with multifactorial etiology including poor parental dietary and hygiene behaviors. AIM: This study aimed to assess toothbrushing-related perceptions among parents with immigrant background living in Norway. DESIGN: A structured interview was performed with immigrant parents to assess their oral health-related knowledge, beliefs, and attitude toward toothbrushing. Immigrant parents of non-Western origin with newborn infants (0-6 months) were included in this study. RESULTS: Of those interviewed, 66% chose to participate and they were found to have an average favorable attitudes, subjective norms, and strong perceptions of control related to child's tooth brushing with reported means of (3.3), (3.6), and (4.6), respectively. They had on average low indulgence (mean 7.8) with respect to this behavior and a relatively high level of knowledge (mean 6.9). Parents with strong intention toward toothbrushing (61%) had on average more frequent oral hygiene behavior than parents with weak intentions. CONCLUSION: Parents with non-Western origin have adequate knowledge and intention toward toothbrushing, although some have an unsatisfactory attitude, which might affect the oral health of their children negatively. Culture and habits are contributing factors in ECC and should be addressed in oral health prevention policies.

Differential Responses of Human Dental Pulp Stromal Cells to Bioceramic Materials: A Comparative In Vitro Study.

AIM: The aim of this study was to compare the effects of white MTA-Angelus (wMTA), Biodentine® (Biodentine) and TotalFill® BC Root Repair MaterialTM putty (TotalFill) on human dental pulp stromal cells (hDPSCs) in vitro. MATERIALS AND METHODS: hDPSCs were isolated from third molars of healthy young adults. Material elutes at different concentrations were prepared. Cells were exposed to the eluates for 1, 3, and 7 days. Cell proliferation was evaluated using 3-(4,5-dimethyl-thiazoyl)-2, 5-diphenyl-tetrazolium bromide assay. The expression of alkaline phosphatase (ALP), osteoprotegerin (OPG), osteocalcin (OC), collagen1A (Col1A), runt-related transcription factor 2 (RUNX2), vascular endothelial growth factor-A (VEGF-A), fibroblast growth factor-1 (FGF-1), interleukin 6 (IL6), tumor necrosis factor alpha (TNFα), and interleukin-1-beta (IL1ß) was determined by reverse transcription-polymerase chain reaction (RT-PCR). VEGF-A protein levels and ALP activity were quantified in the culture supernatant. Data were analyzed by two-way analysis of variance (ANOVA). p values <0.05 were considered statistically significant. RESULTS: hDPSC proliferation was decreased in a dose-related manner for all materials on day 3. The same effect was observed with wMTA and TotalFill on day 7. RT-PCR showed that Biodentine increased the expression of the osteogenic markers ALP, OPG, and OC. TotalFill decreased the ALP expression and activity, enhanced the production of angiogenic VEGF-A, and downregulated the inflammatory IL6 on day 7. CONCLUSION: Although the tested materials are used interchangeably in vital pulp therapy, the findings showed varied hDPSC responses. Biodentine did not affect cell proliferation and increased the expression of osteo-/odontogenic markers compared to wMTA and TotalFill, whereas TotalFill decreased cell proliferation and exhibited enhanced angiogenic and anti-inflammatory effects over time. CLINICAL SIGNIFICANCE: The clinical significance of the results needs further investigation in an attempt to provide recommendations on the selection of bioceramic pulp capping material under different scenarios of pulpal pathosis.

Inflammatory mediators in saliva and gingival fluid of children with congenital heart defect.

OBJECTIVES: (a) To compare levels of pro- and anti-inflammatory mediators in saliva and gingival crevicular fluid (GCF) in children with and without congenital heart defects (CHD cases and controls) and to test whether a systemic component exists in CHD cases by controlling for gingivitis and plaque scores. (b) To correlate the levels of pro- and anti-inflammatory mediators in GCF and saliva with plaque bacterial composition among CHD cases and controls. MATERIALS AND METHODS: Whole un-stimulated saliva and GCF samples were collected (60 CHD cases, 60 controls [Sudan]) and were analysed for levels of prostaglandin E2 (PGE2), interleukin-1ß (IL-1ß), tumour necrosis factor-α (TNF-α), interleukin-1ra (IL-1ra) and interleukin-10 (IL-10) levels. These levels were correlated with the previously reported levels of four red complex bacteria. RESULTS: Significantly elevated levels of PGE2 and IL-1ß in GCF and IL-1ß and TNF-α in saliva were detected among CHD cases compared with controls. General linear model (GLM) analyses revealed that PGE2 and IL-1ß levels remained significantly higher in GCF and saliva samples, respectively, among CHD cases after controlling for gingivitis and plaque score, whereas TNF-α and IL-10 levels were significantly lower in their GCF samples. Additionally, IL-1ß level was significantly positively correlated to the counts of the four red complex species in their GCF. CONCLUSION: In addition to higher levels of some pro-inflammatory mediators in saliva and GCF corresponding to more gingivitis in CHD cases, also a systemic inflammatory component exists and is reflected in these two oral fluids.

Tricalcium silicate cements: osteogenic and angiogenic responses of human bone marrow stem cells.

Tricalcium silicate cements (TSCs) are used in endodontic procedures to promote wound healing and hard tissue formation. The aim of this study was to evaluate and compare the effect of commonly used TSCs [mineral trioxide aggregate (MTA), Biodentine, and TotalFill] on cellular metabolism and osteogenic/angiogenic differentiation of human bone marrow mesenchymal stem cells (hBMSCs) in vitro. We tested the null hypothesis of no difference between MTA, Biodentine, and TotalFill in stem cell responses. Cells were subjected to eluates of the tested materials for up to 14 d. Cell viability was evaluated using the 3-(4,5-dimethyl-thiazoyl)-2,5-diphenyl-tetrazolium bromide (MTT) assay. Real-time PCR was used to determine the levels of expression of the osteogenic factors alkaline phosphatase (ALP), osteoprotegerin (OPG), osteocalcin (OC), and collagen 1A (COL1A1), and the angiogenic factors vascular endothelial growth factor A (VEGFA) and fibroblast growth factor 1 (FGF1). ELISAs were used to measure the levels of VEGFA and ALP in culture supernatants. Mineralization in vitro of hBMSCs was assessed using Alizarin Red staining. The hBMSCs tolerated exposure to TSCs well, with Biodentine showing the most favorable effect on cell viability. Expression of ALP, COL1A1, OPG, and VEGFA were differentially affected by the materials, with Biodentine and TotalFill inducing earlier changes at gene level. Increased mineralization was observed with time, after exposure to all TSCs tested, with MTA showing the greatest effect. The results revealed different responses of hBMSCs to TSCs in vitro.

Presence of plaque, gingivitis and caries in Sudanese children with congenital heart defects.

OBJECTIVES: The objective of this study is to assess the presence of plaque, gingivitis, and caries in a group of Sudanese children with congenital heart defects CHDs (cases) and compare them to children without CHDs (controls). MATERIALS AND METHODS: This analytical cross-sectional study included cases (N = 111, with a mean age of 7.2 ± 3.0 years) and controls (N = 182, with a mean age of 7.2 ± 2.8 years) from Khartoum, Sudan. Examinations were done by two calibrated dentists using plaque index, gingival index, and WHO (World Health Organization) caries diagnostic criteria (dmft/DMFT index: decayed, missing, and filled teeth). RESULTS: Children with CHDs (cases) had statistically significantly higher mean number of sites with plaque and gingivitis than children without CHDs (controls), although almost all children experienced plaque. Cases also experienced significantly higher mean dmft/DMFT than controls (age group 1, 3-7 years: 3.7 vs 2.3 and age group 2, 8-12 years: 1.3 vs 0.6). The Significant Caries Indices in cases (age groups 1 and 2) were also significantly higher than among controls (SiC 8.2 vs 5.9 and 1.8 vs 0.8, respectively). Fillings were totally lacking among cases and scarce among controls. CONCLUSIONS: The findings clearly showed that this group of Sudanese children with CHDs was more severely affected with gingivitis and caries than the control group without CHDs. These results are cause for concern in children at risk of developing systemic infections and serious complications related to poor oral health. CLINICAL RELEVANCE: These findings provide important baseline data for planning appropriate dental preventive strategies for Sudanese children with CHDs.

Cytokine profile in gingival crevicular fluid and plasma of patients with aggressive periodontitis.

OBJECTIVE: This study aimed to determine the content of cytokines in gingival crevicular fluid (GCF) as well as in plasma of Sudanese patients with aggressive periodontitis (AgP) and healthy controls (HC). MATERIALS AND METHODS: Nineteen AgP patients and 19 HC were included. The mean probing pocket depth and clinical attachment level of the GCF sampled sites in patients were both ≥5 mm. The GCF and plasma levels of 27 cytokines were determined using 27-multiplex fluorescent bead-based immunoassays. Ratios were calculated among cytokines of the T-helper cell subsets Th1 and Th2. Descriptive statistics, the Mann-Whitney U-test and Spearman's rho rank correlation coefficient analysis were used. RESULTS: Interferon-γ was the only cytokine found in significantly lower levels in GCF of patients compared with HC. Levels of interleukin (IL)-10, IL-13, IL-1Ra, monocyte chemoattractant protein-1 (MCP-1), regulated on activation normal T-cell expressed and secreted (RANTES), granulocyte-colony-stimulating factor (G-CSF), and granulocyte-macrophage-CSF (GM-CSF) were significantly lower in plasma of AgP compared with HC. The ratios of Th1:Th2 in GCF and Treg:Th17 in plasma were significantly lower in AgP. CONCLUSIONS: The lower levels of cytokines detected systemically in plasma of AgP patients may have an impact on the immune response. The lower ratio of Th1:Th2 cytokines in GCF samples of AgP patients suggests a role for Th2 at the local site of disease.

Pattern of clefts and dental anomalies in six-year-old children: a retrospective observational study in western Norway.

OBJECTIVES: Clefts of the lip and/or palate (CL/P) are the most common congenital disorders of the head and neck. In Norway, the incidence is 1.9/1000 live births. The aim of this study was to investigate the frequency and distribution of various types of clefts and dental anomalies in patients treated by the cleft lip and palate (CLP) team in Bergen, Norway. MATERIAL AND METHODS: The material comprised the records of patients 6 years of age, examined by the CLP team in Bergen from spring 1993 to autumn 2012, incomplete records were excluded. The records of 989 patients were analysed, using frequencies and Chi-square test to compare differences in percentages between groups. RESULTS: The gender distribution was 58.8% male and 41.2% female. Isolated cleft palate (CP) was the most common condition (39.5%). Clefts of the lip, jaw and palate (CLP) constituted (30%) of cases and (30.5%) had isolated cleft lip (CL). The frequencies of agenesis, supernumerary and peg-shaped teeth were (36.5%), (17.8%) and (7.5%), respectively. Over 50% of the study population were diagnosed with one or more malocclusion. Of the CLP patients, 61.4% had Angle Class III occlusion. Statistical analysis disclosed a positive association of agenesis with Class III occlusion (OR =1.8, p≤ 0.001). CONCLUSIONS: The findings supported the hypothesis that the distribution of dental anomalies and occlusal disorders varied among patients with CL, CP and CLP. In patients with cleft, there is a twofold chance to get Class III malocclusion in the presence of agenesis.

Conditioned medium from human bone marrow stromal cells attenuates initial inflammatory reactions in dental pulp tissue.

AIM: To evaluate the effect of MSC-conditioned medium (CM) on the secretion of pro- and anti-inflammatory cytokines from dental pulp cells (hDPC) in vitro, and on the gene expression in vivo after replantation of rat molars. MATERIALS AND METHODS: hDPC were cultured in CM for 24 h, and the concentration of interleukin IL-10, IL-4, IL-6, and IL-8, regulated on activation, normal T Cell expressed and secreted (RANTES), and prostaglandin E2 (PGE2 ) in the media were measured by multiplex assay and ELISA, respectively. Expression of cyclooxygenase-2 (COX-2) was also examined by Western blot analysis after 24 h. Left and right maxillary first rat molars (n = 20) were elevated for 2 min and then replanted with or without application of CM into the tooth sockets. Levels of IL-1ß, IL-10, IL-4, IL-6, and IL-8, and tumor necrosis factor-alpha (TNF-α) mRNA were evaluated by real-time qRT-PCR 3 and 14 days following tooth replantation. RESULTS: The production of IL-8, IL-10, and IL-6, RANTES and PGE2 by cells cultured in CM was significantly higher than production by cells cultured in standard medium (DMEM). At day 3 following replantation in vivo, the levels of IL-1ß and IL-6, and TNF-α mRNA were significantly lower in the CM-treated replanted teeth compared with control teeth. Further, at day 3, the IL-6/IL-10 ratio was significantly lower in the CM-treated replanted teeth compared with control. At day 14 following replantation, no differences in the mRNA ratios were detected between the pulp tissues of replanted and control teeth. CONCLUSIONS: These findings indicated that CM promotes secretion of pro- and anti-inflammatory cytokines from hDPCin vitro and attenuates the initial inflammatory response in the rat dental pulp in vivo following tooth replantation.

Influence of type 2 diabetes on local production of inflammatory molecules in adults with and without chronic periodontitis: a cross-sectional study.

BACKGROUND: Pathological changes in periodontal tissues are mediated by the interaction between microorganisms and the host immune-inflammatory response. Hyperglycemia may interfere with this process. The aim of this study was to compare the levels of 27 inflammatory molecules in the gingival crevicular fluid (GCF) of patients with type 2 diabetes, with and without chronic periodontitis, and of chronic periodontitis subjects without diabetes. A putative correlation between glycated haemoglobin (HbA1c) and levels of the inflammatory molecules was also investigated. METHODS: The study population comprised a total of 108 individuals, stratified into: 54 with type 2 diabetes and chronic periodontitis (DM + CP), 30 with chronic periodontitis (CP) and 24 with type 2 diabetes (DM). Participants were interviewed with the aid of structured questionnaire. Periodontal parameters (dental plaque, bleeding on probing and periodontal pocket depth) were recorded. The GCF levels of the 27 inflammatory molecules were measured using multiplex micro-bead immunoassay. A glycated haemoglobin (HbA1c) test was performed for patients with diabetes by boronate affinity chromatography. RESULTS: After adjustment for potential confounders, the DM + CP group had higher levels of IL-8 and MIP-1ß, and lower levels of TNF-α, IL-4, INF-γ, RANTES and IL-7 compared to the CP group. Moreover, the DM + CP group had lower levels of IL-6, IL-7 and G-CSF compared to the DM group. The DM group had higher levels of IL-10, VEGF, and G-CSF compared to the CP group. The levels of MIP-1α and FGF were lower in diabetes patients (regardless of their periodontal status) than in chronic periodontitis subjects without diabetes. Diabetes patients (DM + CP and DM) had higher Th-2/Th-1 ratio compared to the CP group. HbA1c correlated positively with the pro-inflammatory cytokines (Pearson correlation coefficient = 0.27, P value: 0.02). CONCLUSION: Type 2 diabetes and chronic periodontitis may influence the GCF levels of inflammatory molecules synergistically as well as independently. Type 2 diabetes was associated with high Th-2/Th-1 ratio, and modulated the local expression of molecules involved in the anti-inflammatory and healing processes.

Six-year follow-up of a child with familial chylomicronemia syndrome: disease course and effectiveness of gemfibrozil treatment --case report and literature review.

Familial chylomicronemia syndrome (FCS) is a rare autosomal recessive disease affecting lipoprotein metabolism. FCS is estimated to occur in 1 in 1-2 million individuals and can be diagnosed at any age, equally affecting all genders, races, and ethnicities. The condition is characterized by hypertriglyceridemia, which may predispose patients to acute pancreatitis. In this report, we present the case of a now 6-year-old girl with FCS on gemfibrozil and dietary restrictions. The patient initially presented at 40 days of age with vomiting. Serum samples revealed lipemia, with markedly elevated triglyceride levels. The patient was diagnosed with FCS, confirmed by genetic testing showing the homozygous variant c.833C>T(p,Ser278Phe) for the LPL gene. Despite being on a low-fat diet with medium chain triglyceride (MCT) based milk formulas, the patient developed acute pancreatitis 2 months later with continued elevated triglyceride levels. She was placed on gemfibrozil and fat-soluble vitamins at 2 months of age, with marked improvements subsequently noted. Currently, the patient is doing well, with normal growth parameters and no other episodes of acute pancreatitis. Her triglyceride levels have been maintained within normal levels. FCS is a rare, inherited lipid disorder that often goes underdiagnosed and unmanaged. It is worth considering the fibric acid derivative (gemfibrozil) to be one of the lines of management early on after diagnosis.

Orthodontic Status and Association with Oral-Health-Related Quality of Life-A Study of 16-Year-Old Norwegians with a Cleft Lip and Palate.

OBJECTIVE: To assess the association between clinical orthodontic indicators and oral-health-related quality of life, adjusted for socio-demographic factors, focusing on 16-year-old patients with cleft lip and/or palate (CL/P). PARTICIPANTS: One hundred and twenty-two patients with CL/P, representing cleft-lip (CL), cleft-palate (CP), unilateral/bilateral cleft-lip-palate (UCLP/BCLP), enrolled in the national CLP-Team, Bergen, Norway. METHOD: A cross-sectional study by two orthodontists assessing the number of teeth, intermaxillary sagittal relation (ANB-angle), dental arch and occlusion of 16-year-old patients with CL/P. All completed a digital questionnaire including self-reported socio-demographic variables, OHIP-14 questionnaire and dental aesthetics. Cross-tabulations with Pearson's Chi-square test were used to identify associations between self-reported OHRQoL and socio-demographic and clinical indicators. Multiple variable analyses were conducted with binary logistic regression analysis using the odds ratio (OR) and 95% confidence interval (CI) to assess associations between OHRQoL and clinical indicators adjusted for socio-demographic variables. Ethical approval was granted by the regional ethics committee. RESULTS: Patients with UCLP and BCLP had poorer clinical indicators compared to patients with CL and CP (p < 0.05). A total of 80% of the patients had OHIP-14 > 0. The highest oral impact was reported for psychological domains and articulation and the least for functional domains. Respondents with BCLP and those with poor intermaxillary relationships (ANB < 0°) reported a high impact on OHRQoL (p < 0.05). No statistically significant associations between other clinical indicators and socio-demographic variables such as gender, educational aspiration, and place of residence were reported. CONCLUSIONS: The study revealed an association between severe cleft diagnosis, missing teeth, misaligned teeth, negative overjet, and poor OHRQoL, but a statistically significant association was found only between OHRQoL and poor intermaxillary sagittal relations (unfavorable profile). To improve OHRQoL among patients with clefts, there is a need for an individual follow-up and prioritization of oral healthcare.

Child Behavior Problems and Maltreatment Exposure.

OBJECTIVES: Establish the longitudinal cross-lagged associations between maltreatment exposure and child behavior problems to promote screening and the type and timing of interventions needed. METHODS: The Longitudinal Studies of Child Abuse and Neglect, a multiwave prospective cohort study of maltreatment exposure, enrolled children and caregivers (N = 1354) at approximately age 4 and followed them throughout childhood and adolescence. Families completed 7 waves of data collection with each wave occurring 2 years apart. Maltreatment was confirmed using official case records obtained from Child Protective Services. Six-month frequencies of behavior problems were assessed via caregiver-report. Two random-intercept, cross-lagged panel models tested the directional relations between maltreatment exposure and externalizing and internalizing behaviors. RESULTS: Maltreatment exposure predicted increases in externalizing behaviors at ages 8 (b = 1.06; 95% confidence interval [CI] 0.14-1.98), 12 (b = 1.09; 95% CI 0.08-2.09), and 16 (b = 1.67; 95% CI 0.30-3.05) as well as internalizing behaviors at ages 6 (b = 0.66; 95% CI 0.03-1.29), 12 (b = 1.25; 95% CI 0.33-2.17), and 14 (b = 1.92; 95% CI 0.76-2.91). Increases in externalizing behaviors predicted maltreatment exposure at age 12 (odds ratio 1.02; 95% CI 1.00-1.05). CONCLUSIONS: Maltreatment exposure is robustly associated with subsequent child behavior problems, strengthening inferences about the directionality of these relations. Early screening of externalizing behaviors in pediatric settings can identify children likely to benefit from intervention to reduce such behaviors as well as prevent maltreatment exposure at entry to adolescence.
