RESUMO
BACKGROUND: Children with healthier nutritional status are less likely to develop severe caries than those with a high-sugar content diet. Studies evaluating dental caries and nutritional status in school-age children have generally focused on dietary intake, diet quality, or anthropometric measures, and the number of studies evaluating them together is limited. OBJECTIVE: It was aimed to evaluate the relationship between dental caries adherence to the Mediterranean Diet (MD), dietary intake, and Body Mass Index (BMI) in school-age children. MATERIALS AND METHODS: This study was conducted with 300 healthy children (52.0% boys, 48.0% girls) aged between 6 and 12 years. The data collection forms included sociodemographic characteristics, oral health practices of children, Mediterranean Diet Quality Index for children and adolescents (KIDMED), and food consumption records. Anthropometric measurements (body weight and height) of the children were taken. Dental examinations were performed by a pediatric dentist. RESULTS: While the DMFT mean score of the children was 1.7 ± 2.09, the mean dft score was 2.9 ± 3.29. The mean of KIDMED scores was 5.9 ± 3.32. DMFT and dft scores decreased statistically as maternal education increased (p < 0.05). DMFT and dft scores were not statistically different between BMI groups according to gender and age (p > 0.05). DMFT scores differed statistically between KIDMED groups (p < 0.05). This difference was between low-optimal and low-improvement-needed groups. While there was a low negative correlation (r=-0.169) between calcium intake and DMFT score, a low positive correlation was found between glucose (r = 0.172) and fructose (r = 0.149) intake and dft score (p < 0.05). In regression analysis, while the children's age related DMFT scores positively, maternal education and KIDMED scores related DMFT scores negatively. Also, children's age and maternal education related dft scores negatively. CONCLUSION: In this study, adherence to the MD rather than nutrients was found to be important in dental caries. Also maternal education level was also found to be a determinant factor in dental caries in children. DMFT and dft did not differ between BMI groups.Further studies should be conducted to assess the impact of the MD on dental caries in children to develop dietary interventions for preventative purposes.

This study evaluated the relationship between adherence to the Mediterranean diet (MD), sustainable and healthy eating behaviors, and awareness of reducing the ecological footprint. It was conducted with 1333 adults (38.2% male, 61.8% female, mean age 24.2 ± 7.5 years). The questionnaire included socio-demographic characteristics, anthropometric measurements, the Awareness Scale for Reducing Ecological Footprint (ASREF), the Sustainable and Healthy Eating (SHE) Behaviors Scale, and Mediterranean Diet Adherence Scale (MEDAS). 40.2% of the participants adhered to the MD (≥7 scores). Obese individuals' total scores on MEDAS, SHE Behaviors Scale, and ASREF were the lowest (p < 0.05). In regression analysis, education duration, SHE Behaviors Scale total score, and BMI affected the ASREF score (p < 0.05). The education duration, SHE Behaviors Scale scores, and ASREF scores were higher in those in MD-adherence group (p < 0.05). In conclusion, adherence to the MD was associated with higher sustainable and healthy eating behaviors and higher awareness of ecological footprint reduction.

Globally, Non-alcoholic fatty liver disease (NAFLD) has a rising prevalence with no definitive pharmacological treatments. The aim of this study was to assess the clinical effects of wheat germ in patients with NAFLD. Fifty participants with NAFLD were randomly allocated to take 40 g wheat germ (n = 25) or placebo (n = 25) in a randomized double-blind clinical trial over 12 weeks. Transient elastography (FibroScan) determined a diagnosis of NAFLD. After 12 weeks of intervention, reduction in serum alanine aminotransferase (p = 0.006) and γ-glutamyltransferase (p = 0.004), total cholesterol (p = 0.018), triglyceride (p = 0.046), and hepatic steatosis (p = 0.043) levels in the wheat germ group was significantly higher compared to the placebo group. Serum TAC levels in wheat germ group patients increased significantly higher than placebo group (p = 0.001). Reduction in serum hs-CRP level in the wheat germ group was significantly higher than in the placebo group (p = 0.031). In conclusion, our study shows that wheat germ consumption may improve total antioxidant capacity, hepatic steatosis, serum total cholesterol and triglyceride levels, alanine aminotransferase (ALT), and Gamma-glutamyl Transferase (GGT) in NAFLD patients. Longitudinal studies with larger sample sizes are needed to confirm biological effects of wheat germ on NAFLD patients.

This study aimed to determine the relationship between health literacy and ecological footprint which is an indicator of sustainability and environmental impact and to examine the factors that may affect them. It was found that 20.3% of individuals have inadequate, 43.7% problematic, 26.1% sufficient and 10.0% excellent health literacy levels. There were differences in age, education level and BMI classification according to Ecological Footprint Awareness Scale score quartiles and health literacy levels (p < 0.05). It was determined that age and Turkey Health Literacy Scale score had effect on ecological footprint awareness. Individuals with a high level of health literacy have a high awareness of their ecological footprint. The increase in people's health literacy levels and ecological footprint awareness with age can be interpreted as the increase in people's education and knowledge levels and their awareness levels against the protection of nature and the environment.
RESUMO
BACKGROUND: The MF07-01 trial is a multicenter, phase III, randomized, controlled study comparing locoregional treatment (LRT) followed by systemic therapy (ST) with ST alone for treatment-naïve stage IV breast cancer (BC) patients. METHODS: At initial diagnosis, patients were randomized 1:1 to either the LRT or ST group. All the patients were given ST either immediately after randomization or after surgical resection of the intact primary tumor. RESULTS: The trial enrolled 274 patients: 138 in the LRT group and 136 in the ST group. Hazard of death was 34% lower in the LRT group than in the ST group (hazard ratio [HR], 0.66; 95% confidence interval [CI], 0.49-0.88; p = 0.005). Unplanned subgroup analyses showed that the risk of death was statistically lower in the LRT group than in the ST group with respect to estrogen receptor (ER)/progesterone receptor (PR)(+) (HR 0.64; 95% CI 0.46-0.91; p = 0.01), human epidermal growth factor 2 (HER2)/neu(-) (HR 0.64; 95% CI 0.45-0.91; p = 0.01), patients younger than 55 years (HR 0.57; 95% CI 0.38-0.86; p = 0.007), and patients with solitary bone-only metastases (HR 0.47; 95% CI 0.23-0.98; p = 0.04). CONCLUSION: In the current trial, improvement in 36-month survival was not observed with upfront surgery for stage IV breast cancer patients. However, a longer follow-up study (median, 40 months) showed statistically significant improvement in median survival. When locoregional treatment in de novo stage IV BC is discussed with the patient as an option, practitioners must consider age, performance status, comorbidities, tumor type, and metastatic disease burden.

OBJECTIVE: This study aimed to evaluate the relationship between adherence to the Mediterranean diet (MD), mindful eating, environmental beliefs, and obesity in children. MATERIALS AND METHODS: The study included 318 children (50.6% male, 49.4% female, 10.0 ± 0.73 years old). Data were obtained using survey and a face-to-face interview method. The questionnaire includes general information, anthropometric measurements, the New Ecological Paradigm Scale for Children (NEP), the Mediterranean Diet Quality Index for children and adolescents (KIDMED), and the Mindful Eating Questionnaire for Children. RESULTS: According to the KIDMED classification, 52.5% of the children were in the group that needs improvement, 35.2% were in the low diet quality group, and 12.3% were in the optimal MD group. The Mindless score was higher in overweight/obese children compared to the normal body mass index (BMI) group (P < .05). Awareness, NEP, and KIDMED scores were the lowest in overweight/obese children (P < .05). In regression analysis, the father's age, KIDMED, and Awareness scores related to NEP scores positively (R2 : 0.545, P < .001). Also, children's body mass index-related KIDMED scores negatively, and awareness and NEP scores related KIDMED scores positively (R2 : 0.276, P < .001). CONCLUSION: Our results show that higher adherence to the MD is associated with higher environmental beliefs. Children with higher mindful eating have higher environmental beliefs and adherence to the MD, and these scores are lower in obese children. Therefore, raising generations that adopt sustainable diet models and have high environmental awareness is necessary. This research provides significant findings for future clinical studies on children's body weight maintenance and sustainability. Cite this article as: Bozkurt O, Kocaadam-Bozkurt B, Koçyigit E.

RESUMO
The relationship between organic food consumption, awareness of reducing ecological footprint, and orthorexia nervosa (ON) tendencies has yet to be explored in detail. This study aimed to determine factors related to organic food consumption and ON tendencies in young adults. Also, the relationship between organic food consumption, awareness of reducing ecological footprint, and ON tendencies was investigated. This study was conducted with 887 young adults (58.4% female, 41.6% male, aged 18-25 years, mean age 20.8 ± 2.55 years). Study data were obtained with a web-based questionnaire. The questionnaire included socio-demographic characteristics, anthropometric measurements, the Organic Food Consumption Scale (OFC), ORTO-11, and the Awareness Scale for Reducing Ecological Footprint (ASREF). While 17.2% were overweight or obese, 74.9% had a normal body weight. There were no differences by sex in terms of ORTO-11, OFC, and ASREF total scores (p > .05). Significant positive correlations were found between ASREF and OFC (p < .001), while negative correlations were found for ORTO-11 and OFC (p < .001). A higher ASREF and increased ON tendencies predicted increased organic food consumption (p < .05). Furthermore, higher organic food consumption behaviors and awareness of reducing ecological footprint predicted increased ON tendencies (p < .05). Findings from this study will contribute to a deeper understanding of the factors associated with organic food consumption and ON tendencies among individuals. By shedding light on the interplay between ecological awareness, organic food consumption, and orthorexic tendencies, policymakers and health professionals can develop targeted interventions to promote sustainable and healthy food consumption.
RESUMO
Severe aplastic anemia (SAA) is a life-threatening hematological disease characterized by the suppression of the bone marrow. Patients with SAA are predisposed to recurrent bacterial infections and invasive fungal infections (IFI) due to profound and persistent neutropenia. Mucorales are the second most common cause of IFI encountered in SAA. Here we present a pediatric case of SAA with active mucormycosis infection of the paranasal sinuses. In the first step, surgical debridement was performed and combined antifungal therapy (liposomal amphotericin B, posaconazole, caspofungin) was started. Due to severe neutropenia, daily granulocyte transfusion was added to therapy. Hyperbaric oxygen therapy was applied for wound healing. After all this the patient went under flap surgery. One week after the successful flap procedure, HSCT was performed and he had no complications related to HSCT. The patient was followed in the outpatient clinic for 6 months with posaconazole. Now, he is out of drugs and followed without problems for 15 months after HSCT. Our case confirms that urgent HSCT with multiple therapies (surgical debridement, granulocyte support, combined antifungal therapy, hyperbaric O2) is crucial for saving life in SAA patients with active mucormycosis.
RESUMO
Plants evolve to synthesize various natural metabolites to protect themselves against threats, such as insects, predators, microorganisms, and environmental conditions (such as temperature, pH, humidity, salt, and drought). Plant-derived toxic proteins are often secondary metabolites generated by plants. These proteins, including ribosome-inactivating proteins, lectins, protease inhibitors, α-amylase inhibitors, canatoxin-like proteins and ureases, arcelins, antimicrobial peptides, and pore-forming toxins, are found in different plant parts, such as the roots, tubers, stems, fruits, buds, and foliage. Several investigations have been conducted to explore the potential applications of these plant proteins by analyzing their toxic effects and modes of action. In biomedical applications, such as crop protection, drug development, cancer therapy, and genetic engineering, toxic plant proteins have been utilized as potentially useful instruments due to their biological activities. However, these noxious metabolites can be detrimental to human health and cause problems when consumed in high amounts. This review focuses on different plant toxic proteins, their biological activities, and their mechanisms of action. Furthermore, possible usage and removal strategies for these proteins are discussed.

OBJECTIVES: This study aims to examine the validity and reliability of the children's eating attitudes test (ChEAT) in Turkish children. METHODS: The participants were 331 children (137 boys and 194 girls, ages 8-15). Data was collected through face-to-face interviews using a questionnaire containing socio-demographic characteristics, the ChEAT, and the children's eating behaviour questionnaire (CEBQ). Exploratory factor analysis (EFA) was performed to determine the factor structure of the Turkish version of the ChEAT. Additionally, the reliability was examined in terms of internal consistency and test-retest reliability. All statistical analyses were performed using Mplus Trial Version and SPSS 11.5 (SPSS, Chicago, IL, USA). RESULTS: According to the goodness-of-fit statistic, a three-factor solution was appropriate and compatible with clinical considerations. The three factors explained 50.1% of the variance. Cronbach's alpha coefficient was 0.75 for ChEAT-26, 0.67 for "Preoccupation with thinness and food", 0.63 for "Social pressure to eat", and 0.71 for "Dieting". Furthermore, the test-retest reliability was 0.72, 0.62, 0.59, and 0.59 respectively. Statistically significant correlations between the ChEAT and CEBQ were found (p < 0.05). "Preoccupation with thinness and food" was significantly higher in obese children (p < 0.05), while "Social pressure to eat" was lower (p < 0.001). Sex, grade, BMI, parental education in addition to working status affected the ChEAT-26 scores. CONCLUSIONS: The present study has provided preliminary evidence for the validity and reliability of a Turkish version of the ChEAT.
Early diagnosis and intervention of abnormal eating attitudes are crucial to minimizing adverse physical as well as psychological health outcomes such as obesity or being underweight for children with eating disorders. Since eating disorders occur early, screening for nutritional attitudes along with behaviors is crucial. The Children's Eating Attitudes Test (ChEAT) was developed by Maloney et al. to evaluate eating attitudes and behaviors in children. This study aimed to adapt the ChEAT-26 to Turkish and evaluate its validity and reliability. The present study has provided preliminary evidence for the validity and reliability of a Turkish version of the ChEAT. High scores on ChEAT-26 indicate the severity of the eating disorder.
RESUMO
Aim: The Planetary Health Diet Index (PHDI) is a relatively new index, and studies about its relationship with eating behaviors, nutritional status, and obesity in adults are very limited. For this reason, in this study, sustainable healthy eating behaviors of individuals and compliance of their diets with PHDI were evaluated. Methods: This cross-sectional study was conducted with 1,112 adults (70.1% women and 29.9% men with mean age = 28.7 years, SE = 9.47). Study data were obtained with the face-to-face interview method via a questionnaire including sociodemographic characteristics, anthropometric measurements, the Sustainable and Healthy Eating (SHE) Behaviors Scale, and 24-h dietary recall. PHDI was evaluated for adherence to EAT-Lancet Commission recommendations. Results: The average PHDI total score was 41.5 points. Higher SHE Behaviors Scale and PHDI scores were observed in participants with a duration of education above 8 years (p < 0.05). Those with lower SHE Behaviors Scale and PHDI scores were more likely to be obese (p < 0.001). The total PHDI score was positively associated with fiber, vitamin E, potassium, and folate, and negatively associated with pyridoxine and calcium (p < 0.05). The total SHE Behaviors Scale score was positively associated with carbohydrates, fiber, and potassium and negatively associated with pyridoxine, calcium, and energy (p < 0.05). A one-unit increase in SHE Behaviors Scale total score resulted in a 5,530 unit (95%CI: 4.652; 6.407) increase in PHDI total score and a one-unit increase in duration of education (years) resulted in a 0.660 unit (95%CI: 0.403; 0.918) increase in PHDI total score. Furthermore, a one-unit increase in Body Mass Index (BMI) (kg/m2) resulted in a - 0.218 unit (95%CI: -0.424; -0.013) decrease in PHDI total score. Conclusion: The participants' PHDI index scores were low; therefore, the adherence to the EAT-Lancet recommendation was low which might be associated with obesity. Clinical studies evaluating the effects of adherence to sustainable diets on adequate and balanced nutrition and health outcomes are recommended.
RESUMO
Introduction: Background: adolescence is a critical period for developing healthy eating habits. It is crucial to evaluate and encourage adherence to the Mediterranean diet, a sustainable and healthy diet model in this age group. Objective: this study aimed to evaluate the relationship between adherence to the Mediterranean diet and anthropometric measurements and nutritional status in Turkish adolescents. Material and methods: the demographic characteristics, health information, nutritional habits, physical activity status, and 24-hour dietary recall of the adolescents were obtained with a questionnaire. Adherence to Mediterranean diet was evaluated with the Mediterranean-Style Dietary Pattern Score (MSDPS). Results: a total of 1,137 adolescents (mean age 14.0 ± 1.37 years) were included; 30.2 % of the boys and 39.5 % of the girls were overweight/obese. The median (interquartile range) value of the MSDPS was 10.7 (7.7), and this value was 11.0 (7.6) for the boys and 10.6 (7.4) for the girls (p > 0.05). The levels of protein, fiber, vitamin A, vitamin C, folate, vitamin B12, iron, magnesium, zinc, and potassium intake increased with adherence to Mediterranean diet (p < 0.001). Age, parental education level, body mass index (BMI), waist circumference, and skipping meals affected MSDPS. Conclusion: adolescents' adherence to the Mediterranean diet was low and correlated with some anthropometric measures. Increasing adherence to the Mediterranean diet may contribute to preventing obesity and adequate and balanced nutrition in adolescents.
Introducción: Introducción: la adolescencia es un periodo crítico para el desarrollo de hábitos alimentarios saludables. Es fundamental evaluar y fomentar la adherencia a la dieta mediterránea, un modelo de alimentación sostenible y saludable en este grupo de edad. Objetivo: este estudio tuvo como objetivo evaluar la relación entre la adherencia a la dieta mediterránea y las medidas antropométricas y el estado nutricional en adolescentes turcos. Material y métodos: las características demográficas, la información de salud, los hábitos nutricionales, el estado de actividad física y el recuerdo dietético de 24 horas de los adolescentes se obtuvieron mediante un cuestionario. La adherencia a la dieta mediterránea se evaluó con el Mediterranean-Style Dietary Pattern Score (MSDPS). Resultados: se incluyó un total de 1.137 adolescentes (edad media 14,0 ± 1,37 años). El 30,2 % de los niños y el 39,5 % de las niñas tenían sobrepeso/obesidad. El valor de la mediana (rango intercuartílico) del MSDPS fue de 10,7 (7,7), siendo este valor de 11,0 (7,6) para los niños y de 10,6 (7,4) para las niñas (p > 0,05). Los niveles de ingesta de proteína, fibra, vitamina A, vitamina C, folato, vitamina B12, hierro, magnesio, zinc y potasio aumentaron con la adherencia a la dieta mediterránea (p < 0,001). La edad, el nivel de educación de los padres, el índice de masa corporal (IMC), la circunferencia de la cintura y la omisión de comidas afectaron al MSDPS. Conclusión: la adherencia a la dieta mediterránea de los adolescentes fue baja y se correlacionó con algunas medidas antropométricas. El aumento de la adherencia a la dieta mediterránea puede contribuir a la prevención de la obesidad y a una nutrición adecuada y equilibrada en los adolescentes.

UNLABELLED: The aim of this study was to demonstrate demographics of 39 consecutive Spinal Muscular Atrophy (SMA) type 1 patients diagnosed genetically in a tertiary center between June 2006 and June 2009. There was history of consanguineous marriage in 27 (69%) patients. The average patient lifespan was 251 days (30-726 days). The average patient age at diagnosis was 129 days (33-297 days). A statistically significant correlation was found between the age at diagnosis and the lifespan (p = 0.00). No significant correlation was found between the time spent in intensive care and the lifespan (p = 0.43). Routine physical therapy was found to have no significant impact on the lifespan average (p = 0.17). The cause of death in all of our patients was respiratory issues. Genetic counseling was given to 35 families. A second child with SMA was born in three out of the 14 families who declined prenatal diagnosis. CONCLUSION: A national program is needed in Turkey for SMA prevention and creation of expert teams for the management of these patients.

Type 2 diabetes mellitus (T2DM) is a substantial issue in public health. Recently, there has been considerable interest in the effectiveness of using herbal supplements for T2DM. Among the herbal supplements, turmeric (Curcuma longa L.) has been attracting an avalanche of attention owing to its main component, curcumin. This review examines the physiological activities and mechanisms of action of curcumin associated with T2DM and its complications. The literature indicates that pro-inflammatory cytokines along with oxidative stress play a very important role in diabetes pathogenesis. Since inflammation is a main cause of disruption of the ß cell structure, the anti-diabetic characteristic of curcumin is mainly attributed to its anti-inflammatory as well as anti-oxidant activities. In addition to these activities, curcumin has been developed as a promising prevention/treatment choice for diabetes complications by modulating various critical signal steps owing to the anti-hyperglycemic and anti-hyperlipidemic activities of curcumin. Studies on diabetic humans and animals have revealed that curcumin may have positive effects on oxidative stress and inflammation and may reduce fasting blood glucose levels, increase insulin sensitivity/secretion and regulate the lipid profile. Thus, it may prevent and treat diabetes by affecting various molecular targets.

Aim: Parental behaviors and the home environment are two of the most effective ways to adopt healthy eating and active lifestyles. For this reason, it is crucial to understand children's nutritional habits, analyze the dynamics related to parental factors, diagnose and treat childhood obesity in the early period, and prevent adulthood obesity. This study aimed to explore how parenting influences children's nutritional status, physical activity, and BMI. Methods: The study involved 596 children with their parents. The data were collected through face-to-face interviews using the survey method. The survey consists of descriptive information (age, gender, educational status), anthropometric measurements, nutritional habits, Family Nutrition and Physical Activity Scale (FNPA), International Physical Activity Questionnaire, and 24-h dietary recall. The Mean Adequacy Ratio (MAR) was applied to assess dietary adequacy. Results: Most mothers and fathers were overweight or obese (61.6 and 68.7%, respectively). 38.6% of boys and 23.1% of girls were overweight or obese. The FNPA score was positively correlated with MAR (p < 0.05). Multiple linear regression analysis revealed that children's BMI was negatively correlated with FNPA score, while maternal BMI and father's BMI were positively correlated (p < 0.05). Furthermore, dietary energy was not associated with the child's BMI but with dietary adequacy (p < 0.05). There was no evidence that family impacted children's physical activity. Conclusion: This study supports that parenting influences children's dietary intake and BMI. Adequate and balanced nutrition, regardless of dietary energy, may affect children's body weight. Family plays a significant role in influencing and forming children's lifestyle-related behaviors. Children's healthy eating and physical exercise habits can be encouraged through school-based programs involving families.
RESUMO
Objectives: Although the relationship between breast cancer (BC) risk factors and mammographic density (MD) patterns is not clear, high MD is well known as an independent risk factor for BC. Thus, the aim of this study was to examine the association between MD and BC risk factors in BC patients and find a correlation between MD and tumor characteristics in BC patients. Methods: Our data included 242 patients with BC. Furthermore, the MD (type I - <25%; type II - 25-50%; type III - 51-75%; and type IV - >75%) was categorized according to percentile density, and the various types of MD were compared using risk factors for BC and tumor characteristics of patients. Results: The results of this study indicated that younger age, pre-menopausal status, younger menarche age, nulliparity, low body mass index, and smoking significantly increase the percentage of MD (p<0.001, p<0.001, p=0.04, p<0.001, p=0.003, and p=0.01, respectively). Moreover, the distribution of MD patterns showed significant differences according to tumor subtypes. Type 4 mammographic pattern was higher in patients with human epidermal growth factor receptor 2 (Her2) type of tumor (p=0.01). Conclusion: Higher MD is related to reproductive risk factors and tumor subtypes, especially Her2 type, in BC patients. Further studies are needed to identify the factors related to breast density.
RESUMO
The role of the gut microbiota in human health is one of the most important research topics. There is a strong relationship between the microbiota-gut-brain axis and cognitive functions. Since Alzheimer's disease (AD) is a disease characterized by cognitive impairment, the influence of the gut microbiota in the development and treatment of the disease attracts considerable attention. Gerobiotics is a new concept that includes probiotics or derived postbiotics involved in delaying the aging process. Increasing evidence in the literature suggests that gerobiotics has important roles in the pathogenesis and progression of AD, and even in its treatment, through various mechanisms of action. Several researchers have established the linkage between ingestion of gerobiotics and improved gut dysbiosis and cognitive functions, nevertheless the dose and duration of treatment differ based on strain. Furthermore, oxidative-inflammatory pathways are mainly involved in the neuroprotective effects caused by gerobiotics. This review provides the effects of gerobiotics on microbiota alteration and modulation in AD.

Inflammation drives colorectal cancer development, and colorectal cancer risk is influenced by dietary factors, including dietary fiber. Hyperactive WNT signaling occurs in colorectal cancer and may regulate inflammation. This study investigated (i) relationships between the inflammatory potential of diet, assessed using the Energy-adjusted Dietary Inflammatory Index (E-DII), and markers of WNT signaling, and (ii) whether DII status modulated the response to supplementation with two types of dietary fiber. Seventy-five healthy participants were supplemented with resistant starch and/or polydextrose (PD) or placebo for 50 days. Rectal biopsies were collected before and after intervention and used to assess WNT pathway gene expression and crypt cell proliferation. E-DII scores were calculated from food frequency questionnaire data. High-sensitivity C-reactive protein (hsCRP) and fecal calprotectin concentrations were quantified. hsCRP concentration was significantly greater in participants with higher E-DII scores [least square means (LSM) 4.7 vs. 2.4 mg/L, P = 0.03]. Baseline E-DII score correlated with FOSL1 (ß = 0.503, P = 0.003) and WNT11 (ß = 0.472, P = 0.006) expression, after adjusting for age, gender, body mass index, endoscopy procedure, and smoking status. WNT11 expression was more than 2-fold greater in individuals with higher E-DII scores (LSM 0.131 vs. 0.059, P = 0.002). Baseline E-DII modulated the effects of PD supplementation on FOSL1 expression (P = 0.04). More proinflammatory diets were associated with altered WNT signaling and appeared to modulate the effects of PD supplementation on expression of FOSL1 This is the first study to investigate relationships between the E-DII and molecular markers of WNT signaling in rectal tissue of healthy individuals.Prevention Relevance: Our finding that more inflammatory dietary components may impact large bowel health through effects on a well-recognized pathway involved in cancer development will strengthen the evidence base for dietary advice to help prevent bowel cancer.

Quantitative gene expression measurements from tumor tissue are frequently compared with matched normal and/or adjacent tumor tissue expression for diagnostic marker gene selection as well as assessment of the degree of transcriptional deregulation in cancer. Selection of an appropriate reference gene (RG) or an RG panel, which varies depending on cancer type, molecular subtypes, and the normal tissues used for interindividual calibration, is crucial for the accurate quantification of gene expression. Several RG panels have been suggested in breast cancer for making comparisons among tumor subtypes, cell lines, and benign/malignant tumors. In this study, expression patterns of 15 widely used endogenous RGs (ACTB, TBP, GAPDH, SDHA, HPRT, HMBS, B2M, PPIA, GUSB, YWHAZ2, PGK1, RPLP0, PUM1, MRPL19, and RPL41), and three candidate genes that were selected through analysis of two independent microarray datasets (IL22RA1, TC22, ZNF224) were determined in 23 primary breast tumors and their matched normal tissues using qRT-PCR. Additionally, 18S rRNA, ACTB, and SDHA were tested using randomly primed cDNAs from 13 breast tumor pairs to assess the rRNA/mRNA ratio. The tumors exhibited significantly lower rRNA/mRNA ratio when compared to their normals, on average. The expression of the studied RGs in breast tumors did not exhibit differences in terms of grade, ER, or PR status. The stability of RGs was examined based on two different statistical models, namely GeNorm and NormFinder. Among the 18 tested endogenous reference genes, ACTB and SDHA were identified as the most suitable reference genes for the normalization of qRT-PCR data in the analysis of normal matched tumor breast tissue pairs by both programs. In addition, the expression of the gelsolin (GSN) gene, a well-known downregulated target in breast tumors, was analyzed using the two most suitable genes and different RG combinations to validate their effectiveness as a normalization factor (NF). The GSN expression of the tumors used in this study was significantly lower than that of normals showing the effectivity of using ACTB and SDHA as suitable RGs in this set of tumor-normal tissue panel. The combinational use of the best performing two RGs (ACTB and SDHA) as a normalization factor can be recommended to minimize sample variability and to increase the accuracy and resolution of gene expression normalization in tumor-normal paired breast cancer qRT-PCR studies.

BACKGROUND: Accuracy in the diagnosis of breast cancer and classification of cancer subtypes has improved over the years with the development of well-established immunohistopathological criteria. More recently, diagnostic gene-sets at the mRNA expression level have been tested as better predictors of disease state. However, breast cancer is heterogeneous in nature; thus extraction of differentially expressed gene-sets that stably distinguish normal tissue from various pathologies poses challenges. Meta-analysis of high-throughput expression data using a collection of statistical methodologies leads to the identification of robust tumor gene expression signatures. METHODS: A resampling-based meta-analysis strategy, which involves the use of resampling and application of distribution statistics in combination to assess the degree of significance in differential expression between sample classes, was developed. Two independent microarray datasets that contain normal breast, invasive ductal carcinoma (IDC), and invasive lobular carcinoma (ILC) samples were used for the meta-analysis. Expression of the genes, selected from the gene list for classification of normal breast samples and breast tumors encompassing both the ILC and IDC subtypes were tested on 10 independent primary IDC samples and matched non-tumor controls by real-time qRT-PCR. Other existing breast cancer microarray datasets were used in support of the resampling-based meta-analysis. RESULTS: The two independent microarray studies were found to be comparable, although differing in their experimental methodologies (Pearson correlation coefficient, R = 0.9389 and R = 0.8465 for ductal and lobular samples, respectively). The resampling-based meta-analysis has led to the identification of a highly stable set of genes for classification of normal breast samples and breast tumors encompassing both the ILC and IDC subtypes. The expression results of the selected genes obtained through real-time qRT-PCR supported the meta-analysis results. CONCLUSION: The proposed meta-analysis approach has the ability to detect a set of differentially expressed genes with the least amount of within-group variability, thus providing highly stable gene lists for class prediction. Increased statistical power and stringent filtering criteria used in the present study also make identification of novel candidate genes possible and may provide further insight to improve our understanding of breast cancer development.
