Autism is associated with genomic instability, which is regulated by telomere length (TL) and index of global methylation (LINE-1). This study will determine relative TL (RTL) and LINE-1 methylation percentage for 69 patients and 33 control subjects to evaluate their potential role as biomarkers for autism. The results displayed a significant decrease of both RTL and LINE-1 methylation in autistic cases relative to controls (P < 0.001). Analysis of receiver operating characteristics curve revealed that both of RTL and LINE-1 methylation percentage have the ability to serve as autism biomarkers (area under the curve = 0.817 and 0.889, respectively). The statistical analysis revealed positive correlation between the two biomarkers (correlation coefficient = 0.439 and P < 0.001). [ABSTRACT FROM AUTHOR]

Purpose: There have been no reports on the application of salivary iodine concentration (SIC) in evaluating iodine nutrition in pregnant women. This study aimed to clarify the relationship between SIC and indicators of iodine nutritional status and thyroid function during pregnancy, to investigate whether salivary iodine can be applied to the evaluation of iodine nutritional status in pregnant women, and to provide a reference basis for establishing a normal range of salivary iodine values during pregnancy. Methods: Pregnant women were enrolled in the Department of Obstetrics, the people's hospital of Yuncheng Country, Shandong Province, from July 2021 to December 2022, using random cluster sampling. Saliva, urine, and blood samples were collected from pregnant women to assess iodine nutritional status, and venous blood was collected to determine thyroid function. Results: A total of 609 pregnant women were included in this study. The median spot urinary iodine concentration (SUIC) was 261 μg/L. The median SIC was 297 μg/L. SIC was positively correlated with SUIC (r = 0.46, P < 0.0001), 24-h UIC (r = 0.30, P < 0.0001), 24-h urinary iodine excretion (24-h UIE) (r = 0.41, P < 0.0001), and estimated iodine intake (EII) (r = 0.52, P < 0.0001). After adjusting for confounders, there was a weak correlation between SIC and serum total iodine and serum non-protein-bound iodine (P = 0.02, P = 0.04, respectively). Pregnant women with a SIC < 176 μg/L had a higher risk of insufficient iodine status (OR = 2.07, 95% CI 1.35–3.19) and thyroid dysfunction (OR = 2.71, 95% CI 1.18–6.21) compared to those with higher SIC. Those having SIC > 529 μg/L were more likely to have excessive iodine status (OR = 2.82, 95% CI 1.81–4.38) and thyroid dysfunction (OR = 3.04, 95% CI 1.36–6.78) than those with lower SIC values. Conclusion: SIC is associated with urinary iodine concentration and thyroid function in pregnant women. SIC < 176 μg/L was associated with an increased risk for iodine deficiency and hypothyroxinemia, while SIC > 529 μg/L was related to excess and thyrotoxicosis. SIC can be used as a reference indicator for evaluating the iodine nutrition status of pregnant women, but it needs further investigation and verification.

Background: Video-assisted thoracoscopic surgery (VATS) often induces significant postoperative pain, potentially leading to chronic pain and decreased quality of life. This study aimed to evaluate the acetaminophen/ibuprofen combination effectiveness in reducing analgesic requirements and pain intensity in patients undergoing VATS. Study design: This is a double-blinded randomized controlled trial. Methods: Adult patients scheduled for elective VATS for lung resection were randomized to receive either intravenous acetaminophen and ibuprofen (intervention group) or 100 mL normal saline (control group). Treatments were administered post-anesthesia induction and every 6 h for three cycles. The primary outcome was total analgesic consumption at 24 h postoperatively. Secondary outcomes were cumulative analgesic consumption at 2 and 48 h; analgesic-related side effects at 2, 24, and 48 h; quality of recovery at 24 h and 48 h postoperatively; pain intensity at rest and during coughing; and rescue analgesics use. Chronic postsurgical pain (CPSP) was assessed through telephone interviews 3 months postoperatively. Results: The study included 96 participants. The intervention group showed significantly lower analgesic consumption at 24 h and 48 h postoperatively (24 h: median difference: − 100 µg equivalent intravenous fentanyl [95% confidence interval (CI) − 200 to − 5 μg], P = 0.037; 48 h: median difference: − 140 μg [95% CI − 320 to − 20 μg], P = 0.035). Compared to the controls, the intervention group exhibited a significantly lower quality of recovery 24 h post-surgery, with no significant difference at 48 h. All pain scores except for coughing at 48 h post-surgery were significantly lower in the intervention group compared to the controls. No significant differences were observed between the groups in postoperative nausea and vomiting occurrence, hospital stay length, and CPSP. Conclusion: Perioperative administration of acetaminophen/ibuprofen significantly decreased analgesic needs in patients undergoing VATS, providing an effective postoperative pain management strategy, and potentially minimizing the need for stronger analgesics.

The aim of the study is to examine the relationship between spiritual well-being, prenatal stress and attachment level of Turkish women conceiving spontaneously or with assisted reproductive techniques (ART). The comparative descriptive study type was conducted between November 2021 and June 2022 with 202 pregnant women, including 87 women conceiving with ART and 115 women conceiving spontaneously, who applied for routine prenatal care checkup in a state hospital in the west of Turkey. Both groups have a high level of spiritual well-being. Pregnant women in the ART group experience higher prenatal distress (9.6% for spontaneous, 12.6% for ART, p = 0.487) and low level of attachment (69.72 ± 7.98 for spontaneous, 66.24 ± 8.88 for ART, p = 0.006) compared to the other group. Additionally, as insufficient partner involvement in the prenatal process increases in pregnant women in both groups, prenatal attachment decreases. It is extremely important that midwives and nurses evaluate the spiritual well-being of pregnant women and provide holistic care in line with their spiritual needs. [ABSTRACT FROM AUTHOR]

Background: Revisional bariatric surgery after an index adjustable gastric band (AGB) may be indicated to remedy weight relapse or band-related complications. We examined outcomes five years following revision from AGB to laparoscopic sleeve gastrectomy (AGB-LSG) or to Roux-en-Y gastric bypass (AGB-RYGB). Methods: We conducted a retrospective review to identify patients (men and women, age 18–80) who underwent one revisional bariatric procedure with AGB as the index procedure at two medical centers in our healthcare system between January 2012 and February 2017. We only included patients with a pre-revision BMI > 30 kg/m2 for whom 5-year follow-up data were available. We compared 5-year weight loss and remission of comorbidities in patients undergoing AGB-LSG and AGB-RYGB conversion. Results: A total of 114 patients met inclusion criteria (65 AGB-LSG, 49 AGB-RYGB). At 5-year post-revision, percent total weight loss (3.4% vs 19.9%; p < 0.001), percent excess weight loss (7.0% vs 50.8%; p < 0.001) and decrease in BMI (1.5 vs 8.8; p < 0.001) was greater in AGB-RYGB vs. AGB-LSG. No significant difference in remission or development of new comorbidities was observed. Conclusion: Conversion of AGB to RYGB is associated with superior intermediate-term weight loss compared to conversion of AGB to LSG. Future multicenter studies with larger sample sizes are necessary to further describe the intermediate-term outcomes of revisional bariatric surgery. [ABSTRACT FROM AUTHOR]

This study aimed to examine self-report of financial leverage, conflict, and satisfaction pertaining to representative payeeship for persons with mental illness, which research has not examined in the past decade. Sixty representative payee recipients with mental illness residing across the U.S. completed an online survey, with most (n = 50) receiving representative payeeship by family members/friends. Wilcoxon-Mann-Whitney tests and Spearman correlations were computed. One-third of participants reported experiencing financial leverage and conflict "sometimes" or more often and were dissatisfied with their representative payee arrangement. With the exception of use of alcohol and/or drugs, no participant characteristic was associated with financial leverage, conflict, or satisfaction. Financial leverage was reported to be greater when representative payees were family members/friends. Financial leverage and conflict were positively associated with each other and negatively associated with satisfaction. It is advisable that satisfaction with representative payeeship be increased and conflict resulting from representative payeeship be minimized. [ABSTRACT FROM AUTHOR]

Background: Topical treatments for atopic dermatitis (AD) used reactively often fail to achieve lasting disease control; many of these therapies are associated with safety concerns that limit long-term use. Crisaborole ointment, 2%, is a nonsteroidal phosphodiesterase 4 inhibitor for the treatment of mild-to-moderate AD that has potential as a long-term maintenance therapy. Objective: The aim was to evaluate the long-term efficacy and safety of crisaborole once daily (QD) compared to vehicle QD as a maintenance therapy to reduce the incidence of flares in patients with AD who previously responded to crisaborole twice daily (BID). Methods: CrisADe CONTROL was a randomized, double-blind, vehicle-controlled, 52-week, phase III study of patients aged ≥ 3 months with mild-to-moderate AD involving ≥ 5% treatable body surface area. Eligible patients received crisaborole BID during an open-label run-in period of up to 8 weeks. Responders were randomly assigned in the double-blind maintenance period to receive either crisaborole QD or vehicle QD. Responders were defined as patients who achieved Investigator's Static Global Assessment (ISGA) success (ISGA score of 0 [clear] or 1 [almost clear] with a ≥ 2-grade improvement) and ≥ 50% improvement in Eczema Area and Severity Index total score (EASI-50) from baseline. Patients who experienced a flare (ISGA score ≥ 2) during the double-blind maintenance period switched to crisaborole BID for up to 12 weeks. During this period, patients were assessed every 4 weeks; if the flare resolved (ISGA score ≤ 1), patients resumed their assigned treatment. The primary endpoint was flare-free maintenance until onset of the first flare. Key secondary endpoints were number of flare-free days, number of flares, and maintenance of pruritus response until onset of the first flare. The incidence of treatment-emergent adverse events was also analyzed. Results: Overall, 497 patients entered the open-label run-in period with crisaborole BID, of which 270 patients were randomized into the 52-week double-blind maintenance period of the study. Of the 270 patients, 135 were randomly assigned to the crisaborole QD group and 135 were randomly assigned to the vehicle QD group. Median time of flare-free maintenance was longer for patients who received crisaborole versus vehicle (111 vs 30 days, respectively; p = 0.0034). The mean number of flare-free days was higher for patients who received crisaborole versus vehicle (234.0 vs 199.4 days, respectively; p = 0.0346). The mean number of flares was lower for patients who received crisaborole versus vehicle (0.95 vs 1.36, respectively; p = 0.0042). No clear trend was observed in maintenance of pruritus response between crisaborole- and vehicle-treated patients. Crisaborole was well tolerated, with no new or unexpected safety findings when used as maintenance treatment. Conclusions: Crisaborole QD was effective and well tolerated for long-term maintenance treatment and flare reduction in adult and pediatric patients with mild-to-moderate AD. Trial Registration: ClinicalTrials.gov, NCT04040192, 31 July 2019. Plain Language Summary: Atopic dermatitis (AD) is an immuno-inflammatory skin disease that can last a long time. It causes skin lesions and intense itching. Topical AD treatments used reactively often fail to control the disease over a long period of time. Many are associated with safety concerns that limit long-term use. Crisaborole ointment is a nonsteroidal treatment for the skin and is used to treat mild-to-moderate AD. Previous studies showed that using crisaborole twice daily was effective and had few side effects in patients with mild-to-moderate AD. This study evaluated how effective and safe long-term treatment with once-daily crisaborole was compared with an ointment with no drug (vehicle). The study included patients aged ≥ 3 months with mild-to-moderate AD whose AD improved after previous treatment with twice-daily crisaborole. This study was designed to investigate how much crisaborole reduced the incidence of AD flares over 52 weeks in these patients. The study included 270 patients whose AD had improved after treatment with twice-daily crisaborole. Of these patients, 135 were randomly assigned to receive crisaborole once a day and 135 to receive vehicle once a day. Patients who received crisaborole had a significantly longer time before experiencing AD flares than those who received vehicle. Crisaborole was well tolerated, and no new or unexpected side effects were found when used as a once-daily maintenance treatment for 52 weeks. These results indicate that once-daily treatment with crisaborole could be a potential long-term maintenance treatment option in children and adults with mild-to-moderate AD. [ABSTRACT FROM AUTHOR]

An inverse relationship between religiousness/spirituality (R/S) and psychometric intelligence (IQ) is well-documented in previous literature. However, the studies that have examined group differences on IQ regarding R/S have limited generalizability. The present study contributed to the literature by evaluating IQ among participants identifying as differentially religious/spiritual (i.e., religious only, spiritual only, both religious and spiritual, or neither religious nor spiritual) and among those classified as either Christian/Catholic, Atheist, or Agnostic. Four hundred and thirty-two participants (M age = 37.9; 36% men) participated online via Amazon's Mechanical Turk as part of a larger study and completed a brief measure of IQ, a scale of religiousness and spirituality, and a demographics questionnaire. Correlations between IQ and self-reported religiousness/spirituality were small and negative (Mean r = −0.17), consistent with previous literature. Multivariate analyses of covariance (MANCOVAs) controlling for age, gender, education, and socioeconomic status (operationalized by estimated annual household income) indicated that IQ scores tended to be lowest (p < 0.001) for "religious only" participants (estimated marginal mean [EMM] = 93.0) and highest for "neither religious nor spiritual" participants (EMM = 103.7). Furthermore, IQ scores were significantly lower (ps < 0.001) for Christian/Catholic participants (EMM = 96.7) compared to both Atheist (EMM = 104.9) and Agnostic participants (EMM = 107.5). Discussion of these findings, relationships to previous theoretical and empirical work, limitations of the present study, and directions for future inquiry are provided. [ABSTRACT FROM AUTHOR]

Research on the relationship between rainfall variability and conflicts has yielded contradictory results. This study is the first to show that the significance of the impact of rainfall variability on conflicts depends on the temporal unit of analysis. We prove this point by comparing the statistical significance of the linkages between georeferenced conflicts and rainfall variabilities at the monthly and annual levels with panel data analyses from 1989 to 2020. We find that a 10 percent increase in monthly rainfall decreases the risk of conflict incidence by 0.0298 percent, but annual rainfall variability is not statistically linked to conflict outbreaks. These statistically significant disparities result from the aggregation of data dispersion and the disregard for the timing of the impact of rainfall on conflicts. These findings highlight the importance of information on monthly rainfall variation when estimating the impact of rainfall on conflicts. [ABSTRACT FROM AUTHOR]

The latest data from the T2K and NO ν A experiments show a tension in their preferred values of the oscillation parameters. In this work, we try to identify the source of the tension between the data from these two experiments. An analysis of their data from various channels (individually, and combined) shows that the tension arises primarily from the ν e appearance data, and is compounded by the ν ¯ μ disappearance data. We provide an explanation for the tension based on parameter degeneracies. Apart from the analysis with the standard matter effect, we also analyse the data with the vacuum oscillation hypothesis. We find that vacuum oscillations fit the data as well as matter effects do; and also reduce the tension between the two experiments. We have also done a study of the future run of NO ν A, T2K and DUNE in the context of establishing this tension with higher statistical significance. [ABSTRACT FROM AUTHOR]

Purpose: Endotrophin is a newly discovered adipokine, and its clinical utility in diagnosing gestational diabetes mellitus (GDM) remains unclear. We aimed to investigate the possible association between endotrophin and GDM and determine its correlation with maternal metabolic parameters. Methods: Screening and diagnosis for GDM were carried out between the 24th and 28th weeks of gestation. The study included 50 patients with GDM and 37 healthy pregnant women. Endotrophin was assayed by a commercially available enzyme-linked immunosorbent assay kit. Results: The endotrophin level was significantly higher in the GDM group compared to uncomplicated pregnancies (121.98 ± 104.08 vs 72.5 ± 76.2, p < 0.05). Furthermore, the fasting glucose, fasting insulin, and HOMA-IR values of and plasma glucose levels obtained at 1 and 2 h after 75 g oral glucose administration were significantly higher in the GDM group than in the control group (p < 0.05). The Spearman analysis showed a statistically significant correlation between the endotrophin level and the fasting glucose, first-hour glucose, fasting insulin, HOMA-IR, and pre-pregnancy and current body mass indexes (BMI) in the GDM group (p < 0.05). Conclusion: Although oral glucose tolerance test (OGTT) is still the gold standard in the diagnosis of GDM, considering the technical difficulties and disadvantages of OGTT, endotrophin measurement at 24–28 weeks of pregnancy in healthy risk-free pregnant women seems to be an appropriate approach to limit the use of OGTT.

Community detection is a fundamental procedure in the analysis of network data. Despite decades of research, there is still no consensus on the definition of a community. To analytically test the realness of a candidate community in weighted networks, we present a general formulation from a significance testing perspective. In this new formulation, the edge-weight is modeled as a censored observation due to the noisy characteristics of real networks. In particular, the edge-weights of missing links are incorporated as well, which are specified to be zeros based on the assumption that they are truncated or unobserved. Thereafter, the community significance assessment issue is formulated as a two-sample test problem on censored data. More precisely, the Logrank test is employed to conduct the significance testing on two sets of augmented edge-weights: internal weight set and external weight set. The presented approach is evaluated on both weighted networks and un-weighted networks. The experimental results show that our method can outperform prior widely used evaluation metrics on the task of individual community validation. [ABSTRACT FROM AUTHOR]

Purpose: Deep white matter lesions (DWMLs), T2 high-intensity areas in the subcortical white matter on magnetic resonance imaging (MRI), are a clinical phenotype of cerebral small vessel disease. Factors such as age and hypertension have been reported to significantly contribute to the presence and severity of DWMLs in cross-sectional studies. We herein report a 10-year longitudinal study on DWMLs in elderly Japanese subjects to reveal the clinical variables contributing to the progression of DWMLs. Methods: A total of 469 Japanese subjects were invited to participate in the study. Of the participants at baseline, 259 subjects completed the revisit MRI study 10 years later. In those 259 subjects, we evaluated the correlation between the progression of DWMLs and clinical variables, such as the gender, age, and overt vascular risk factors. To clarify the role of hypertension, 200 subjects with grade 1 DWMLs at baseline were categorized into three groups according to their status of hypertension and its treatment. Results: Of the 200 subjects with grade 1 DWMLs, 47 subjects (23.5%) showed progression of DWMLs (progression group). In the progression group, the percentage of subjects with hypertension and the systolic blood pressure values were higher than in the non-progression group. In addition, subjects ≥ 60 years old at baseline tended to show deterioration of DWMLs in the group with hypertension without antihypertensive treatment. Conclusion: The results of this 10-year longitudinal study imply a positive correlation between long-standing hypertension and the progression of DWMLs. [ABSTRACT FROM AUTHOR]

Purpose: The relative advantages of dietary analysis methods, particularly in identifying dietary patterns associated with bone mass, have not been investigated. We evaluated principal component analysis (PCA), partial least-squares (PLS) and reduced-rank regressions (RRR) in determining dietary patterns associated with bone mass.Methods: Data from 1182 study participants (45.9% males; aged 50 years and above) from the North West Adelaide Health Study (NWAHS) were used. Dietary data were collected using a food frequency questionnaire (FFQ). Dietary patterns were constructed using PCA, PLS and RRR and compared based on the performance to identify plausible patterns associated with bone mineral density (BMD) and content (BMC).Results: PCA, PLS and RRR identified two, four and four dietary patterns, respectively. All methods identified similar patterns for the first two factors (factor 1, “prudent” and factor 2, “western” patterns). Three, one and none of the patterns derived by RRR, PLS and PCA were significantly associated with bone mass, respectively. The “prudent” and dairy (factor 3) patterns determined by RRR were positively and significantly associated with BMD and BMC. Vegetables and fruit pattern (factor 4) of PLS and RRR was negatively and significantly associated with BMD and BMC, respectively.Conclusions: RRR was found to be more appropriate in identifying more (plausible) dietary patterns that are associated with bone mass than PCA and PLS. Nevertheless, the advantage of RRR over the other two methods (PCA and PLS) should be confirmed in future studies. [ABSTRACT FROM AUTHOR]

Background: Increased muscle mitochondrial mass is characteristic of elite professional endurance athletes (PAs), whereas increased blood lactate levels (lactatemia) at the same absolute submaximal exercise intensities and decreased mitochondrial oxidative capacity are characteristics of individuals with low aerobic power. In contrast to PAs, patients with metabolic syndrome (MtS) are characterized by a decreased capacity to oxidize lipids and by early transition from fat to carbohydrate oxidation (FATox/CHOox), as well as elevated blood lactate concentration [La] as exercise power output (PO) increases, a condition termed 'metabolic inflexibility'. Objective: The aim of this study was to assess metabolic flexibility across populations with different metabolic characteristics. Methods: We used indirect calorimetry and [La] measurements to study the metabolic responses to exercise in PAs, moderately active individuals (MAs), and MtS individuals. Results: FATox was significantly higher in PAs than MAs and patients with MtS ( p < 0.01), while [La] was significantly lower in PAs compared with MAs and patients with MtS. FATox and [La] were inversely correlated in all three groups (PA: r = −0.97, p < 0.01; MA: r = −0.98, p < 0.01; MtS: r = −0.92, p < 0.01). The correlation between FATox and [La] for all data points corresponding to all populations studied was r = −0.76 ( p < 0.01). Conclusions: Blood lactate accumulation is negatively correlated with FATox and positively correlated with CHOox during exercise across populations with widely ranging metabolic capabilities. Because both lactate and fatty acids are mitochondrial substrates, we believe that measurements of [La] and FATox rate during exercise provide an indirect method to assess metabolic flexibility and oxidative capacity across individuals of widely different metabolic capabilities.

Purpose: We aimed to quantify and compare dietary non-enzymatic antioxidant capacity (NEAC), estimated using two dietary assessment methods, and to explore its relationship with plasma NEAC. Methods: Fifty healthy subjects volunteer to participate in this study. Two dietary assessment methods [a food frequency questionnaire (FFQ) and a 24-hour recall (24-HR)] were used to collect dietary information. Dietary NEAC, including oxygen radical absorbance capacity (ORAC), total polyphenols, ferric-reducing antioxidant power (FRAP) and trolox equivalent antioxidant capacity, was estimated using several data sources of NEAC content in food. NEAC status was measured in fasting blood samples using the same assays. We performed nonparametric Spearman's correlation analysis between pairs of dietary NEAC (FFQ and 24-HR) and diet-plasma NEAC, with and without the contribution of coffee's NEAC. Partial correlation analysis was used to estimate correlations regardless of variables potentially influencing these relationships. Results: FFQ-based NEAC and 24-HR-based NEAC were moderately correlated, with correlation coefficients ranging from 0.54 to 0.71, after controlling for energy intake, age and sex. Statistically significant positive correlations were found for dietary FRAP, either derived from the FFQ or the 24-HR, with plasma FRAP ( r ~ 0.30). This weak, albeit statistically significant, correlation for FRAP was mostly present in the fruits and vegetables food groups. Plasma ORAC without proteins and 24-HR-based total ORAC were also positively correlated ( r = 0.35). Conclusion: The relationship between dietary NEAC and plasma FRAP and ORAC suggests the dietary NEAC may reflect antioxidant status despite its weak in vivo potential, supporting further its use in oxidative stress-related disease epidemiology.

Purpose: Increased awareness of the importance of dietary fibre has led to increased interest in 'functional' fibre components like digestion-resistant maltodextrin (RMD). This randomized, placebo-controlled, double-blind study assessed the effects of RMD in the colonic transit time (CTT) and defecation characteristics (frequency, stool volume and consistency). Methods: Sixty-six healthy adult volunteers (32 men) who did not have a daily defecation habit had a 7-day run-in period before the 21-day intervention period with RMD or placebo. CTT and segmental CTT (SCTT) were assessed by a single abdominal X-ray film taken at the end of both periods after radiopaque marker ingestion. Defecation characteristics and intestinal functions were also assessed, which were self-reported by patients. Intragroup comparisons were evaluated by Student's paired t test, Bonferroni test and Chi-square test, while time comparisons by analysis of variance (ANOVA) and time-by-treatment interaction by repeated-measures ANOVA. Results: Fifty-seven subjects were assessed for CTT (placebo, n = 28; RMD, n = 29). In the RMD group, the total CTT, left SCTT and rectosigmoidal SCTT decreased significantly compared to baseline ( p < 0.01 each; −13.3, −4.7, −8.7 h, respectively). Significant differences between groups were observed in total CTT and left SCTT. Significant time-by-treatment interaction was observed in the RMD group for stool volume ( p = 0.014), increasing 56 % compared to baseline ( p < 0.01), while remained unchanged in the placebo group. Stool consistency was improved only in the RMD group ( p < 0.01). No adverse effects related to study products were observed. Conclusions: The results show that RMD improved CTT, stool volume, stool consistency and some intestinal functions in a healthy population. [ABSTRACT FROM AUTHOR]

Purpose: Two objectives were investigated: (1) to assess the risk of micronutrient deficiencies in relation to weight status in Indian women with a focus on iron but also including zinc, vitamin A and B vitamins and (2) to compare fractional iron absorption between obese (OB) and normal weight (NW) women. Methods: Part 1 was a cross-sectional study including 146 healthy, middle-class women from Bangalore, India, with a BMI between 19 and 40 kg/m. Anthropometrics and blood pressure were measured, and a fasting blood sample was obtained for the analysis of vitamin and mineral status, hepcidin, blood lipids and glucose. In part 2, 16 OB and 13 NW women consumed a standardized test meal labeled with the stable iron isotope Fe. Incorporation of the iron isotope into erythrocytes was measured 14 days later. In addition, iron status, hepcidin and inflammatory markers were determined. Results: In part 1, compared to NW women, overweight/OB subjects had significantly higher C-reactive protein, serum ferritin, soluble transferrin receptor (sTfR) and hepcidin concentrations ( p < 0.05). The odds ratio for having high sTfR concentrations (i.e., low iron status) with increasing BMI was 1.09 (95 % CI 1.02-1.17). None of the other micronutrients investigated showed any differences between weight status groups. In part 2, fractional iron absorption was significantly lower in the OB group compared to the NW group even after controlling for differences in iron status (10.0 ± 6.5 vs. 16.7 ± 4.6 %; p = 0.038). Conclusions: OB women in Bangalore have an increased risk of low iron status and absorb less dietary iron; however, their risk of other micronutrient deficiencies was similar to NW women. Our results clearly demonstrate the importance of considering the double burden of malnutrition in the planning of prevention strategies especially in transition countries with emerging obesity epidemics.

Purpose: This cross-sectional study assesses the relationship between consumption frequencies of food items and high-sensitivity C-reactive protein (hs-CRP) in European children. Methods: Out of the baseline sample ( N = 16.228) of the IDEFICS study, 6.403 children (1.315 boys aged 2 to <6, 1.908 boys aged 6 to <10, 1.204 girls aged 2 to <6 and 1.976 girls aged 6 to <10 years) had hs-CRP measured and the Children's Eating Habits Questionnaire filled, including a food frequency questionnaire. Logistic regression adjusted for body mass index z-score, education of the mother, breast-feeding and self-reported hours of physical activity in a sport club per week was conducted. Results: Mean frequency intake of raw vegetable was lower in boys ( p = 0.022 in young and p = 0.020 in old) and older girls ( p = 0.026) with high hs-CRP concentration, while in younger girls ( p = 0.008) the same occurred with the cooked vegetables. The probability of having higher hs-CRP concentration was significantly associated with having low consumption frequency of vegetables ( p = 0.004 in older boys, raw vegetables; and p = 0.0032 in younger girls, cooked vegetables). Also, honey/jam intake decreased the probability of having higher concentration of hs-CRP, whereas soft drinks with sugar, mayonnaise and cereals milled increased this probability. Conclusions: Out of all food items associated with hs-CRP, frequency intake of vegetables presented more associations across all the analysis. Findings suggest that a high-frequency intake of vegetables is inversely related to an inflammatory status in children. More studies are needed to assess the association between diet and inflammation. [ABSTRACT FROM AUTHOR]

Purpose: Liver is the major site of biotransformation for exogenous toxins, in having a defense system against oxidative stress as well as cytochrome P450 system. Isoliquiritigenin (isoLQ) is an active component present in Glycyrrhizae radix and has been shown to have various biological activities. This study investigated the effect of isoLQ as a liver protectant against oxidative stress, both in vivo and in vitro, and also its molecular mechanisms. Methods: We used tert-butylhydroperoxide-induced hepatocyte damage model and cadmium (Cd)-stimulated liver toxicity animal model, which are assessed by immunoblot and flow cytometry as well as plasma and histopathological parameters. Results: In HepG2 cells, pretreatment of 10 and 30 µM isoLQ significantly inhibited the induction of apoptosis and mitochondrial damage, and production of reactive oxygen species. Moreover, isoLQ induced the activation of nuclear factor erythroid 2-related factor-2 (Nrf2), as indicated by an increase in its nuclear translocation and antioxidant response element-luciferase activity. IsoLQ also induced the expression of Nrf2 target phase II enzymes, such as heme oxygenase-1, glutamate-cysteine ligase catalytic subunit and NAD(P)H:quinone oxidoreductase 1. IsoLQ also induced phosphorylation of extracellular stimuli-regulated kinase (ERK), and its activation of Nrf2 was mediated with ERK-dependent phosphorylation of Nrf2, as determined by its chemical inhibitor. In rats, oral treatment of 5 and 20 mg/kg isoLQ prevented Cd-induced acute hepatic damage, as assessed by plasma parameters and semiquantative histology, such as the modified HAI grading scores and the degenerative regions in hepatic parenchyma. Conclusion: These findings are considered as scientific evidence that isoLQ in licorice has the function of being a hepatic protectant against oxidative damages through ERK-mediated Nrf2 activation.

Purpose: Beneficial effects of green tea (GT) polyphenols against obesity have been reported. However, until this moment the molecular mechanisms of how green tea can modulate obesity and regulates fat metabolism, particularly in adipose tissue, remain poorly understood. The aim of this study was to evaluate the role of GT extract in the adipose tissue of obese animals and its effect on weight gain, metabolism and function (de novo lipogenesis and lipolysis), and the involvement of AMP-activated protein kinase (AMPK). Methods and results: Male Wistar rats were treated with GT by gavage (12 weeks/5 days/week; 500 mg/kg of body weight), and obesity was induced by cafeteria diet (8 weeks). Here, we show that obese rats treated with GT showed a significant reduction in indicators of obesity such as hyperlipidemia, fat synthesis, body weight, and fat depots as compared to those treated with standard control diet. AMPK was induced in adipose tissue in rats that were treated with GT and likely restored insulin sensitivity, increased mRNA expression of GLUT4, reducing the concentrations of plasma and liver lipid content, also stimulating fatty acid oxidation in the same tissue. Importantly, repression of de novo lipogenesis in the adipose tissue, reduced lipid droplets in the liver, and the development of insulin resistance in diet-induced obese rats were accompanied by AMPK activation. Conclusion: Our study identified that metabolic changes caused by GT intake induced AMPK activation and modulate the expression of genes involved in metabolism, particularly in adipose tissue, thus offering a therapeutic strategy to combat insulin resistance, dyslipidemia, and obesity in rats.

Purpose: This study aimed to determine whether fenugreek seed powder could reduce the glycemic response and glycemic index (GI) when added to buns and flatbreads. Methods: In a randomised, controlled crossover trial, ten healthy human subjects (five men, five women) were given 50 g glucose (reference food, twice); buns (0 and 10 % fenugreek seed powder); and flatbreads (0 and 10 % fenugreek seed powder) on six different occasions. Finger prick capillary blood samples were collected at 0, 15, 30, 45, 60, 90 and 120 min after the start of the meal. The palatability of the test meals was scored using Likert scales. Results: The incremental areas under the glucose curve value of buns and flatbreads with 10 % fenugreek (138 ± 17 mmol × min/L; 121 ± 16 mmol × min/L) were significantly lower than those of 0 % fenugreek bun and flatbreads (227 ± 15 mmol × min/L; 174 ± 14 mmol × min/L, P = <0.01). Adding 10 % fenugreek seed powder reduced the GI of buns from 82 ± 5 to 51 ± 7 ( P < 0.01) and to the GI of flatbread from 63 ± 4 to 43 ± 5 ( P < 0.01). Conclusions: These results suggest that replacing 10 % of refined wheat flour with fenugreek seed powder significantly reduces the glycemic response and the GI of buns and flatbreads. Thus, fenugreek powder may be a useful functional ingredient to reduce postprandial glycemia. [ABSTRACT FROM AUTHOR]

Background: Currently no studies have examined the historical performances of Oxford and Cambridge Boat Race crews in the context of performance, pacing and tactics which is surprising as the event has routinely taken place annually for over 150 years on the same course. Objectives: The purpose of this study was twofold, to firstly examine the historical development of performances and physical characteristics of crews over 124 years of the Oxford and Cambridge Boat Race between 1890 and 2014 and secondly to investigate the pacing and tactics employed by crews over that period. Methods: Linear regression modelling was applied to investigate the development of performance and body size for crews of eight male individuals over time from Boat Race archive data. Performance change over time was further assessed in 10-year clusters while four intra-race checkpoints were used to examine pacing and tactics. Results: Significant correlations were observed between performance and time (1890-2014) for both Oxford ( r = −0.67; p < 0.01) and Cambridge ( r = −0.64; p < 0.01). There was no difference in mean performance times for Oxford (1170 ± 88 s) and Cambridge (1168 ± 89.8 s) during 1890-2014. Crew performance times improved over time with significant gains from baseline achieved in the 1950s (Cambridge) and the 1960s (Oxford), which coincided with significant change in the physicality of the competing crews ( p < 0.01). There was no tactical advantage from commencing on either the Surrey or Middlesex station beyond chance alone; however, all crews ( n = 228) adopted a fast-start strategy, with 81 % of victories achieved by the crew leading the race at the first intra-race checkpoint (24 % of total distance). Crews leading the race at the final checkpoint (83 % of total distance; 1143 m) achieved victory on 94 % of occasions. Conclusion: Performances and physical characteristics of the crews have changed markedly since 1890, with faster heavier crews now common. Tactically, gaining the early lead position with a fast-start strategy seems particularly meaningful to success in the Boat Race throughout the years, and has been of greater importance to race outcome than factors such as the starting station.

Background: The inflammatory process associated with obesity mainly arises from white adipose tissue (WAT) alterations. In the last few years, nutritional-based strategies have been positioned as promising alternatives to pharmacological approaches against these pathologies. Our aim was to determine the potential of a rice bran enzymatic extract (RBEE)-supplemented diet in the prevention of metabolic, biochemical and functional adipose tissue and macrophage changes associated with a diet-induced obesity (DIO) in mice. Methods: C57BL/6J mice were fed high-fat diet (HF), 1 and 5 % RBEE-supplemented high-fat diet (HF1 % and HF5 %, respectively) and standard diet as control. Serum cardiometabolic parameters, adipocytes size and mRNA expression of pro-inflammatory biomarkers and macrophage polarization-related genes from WAT and liver were evaluated. Results: RBEE administration significantly decreased insulin resistance in obese mice. Serum triglycerides, total cholesterol, glucose, insulin, adiponectin and nitrites from treated mice were partially restored, mainly by 1 % RBEE-enriched diet. The incremented adipocytes size observed in HF group was reduced by RBEE treatment, being 1 % more effective than 5 % RBEE. Pro-inflammatory biomarkers in WAT such as IL-6 and IL-1β were significantly decreased in RBEE-treated mice. Adiponectin, PPARγ, TNF-α, Emr1 or M1/M2 levels were significantly restored in WAT from HF1 % compared to HF mice. Conclusions: RBEE-supplemented diet attenuated insulin resistance, dyslipidemia and morphological and functional alterations of adipose tissue in DIO mice. These benefits were accompanied by a modulating effect in adipocytes secretion and some biomarkers associated with macrophage polarization. Therefore, RBEE may be considered an alternative nutritional complement over metabolic syndrome and its complications. [ABSTRACT FROM AUTHOR]

Purpose: Epidemiological evidence suggests that chronic consumption of fruit-based flavonoids is associated with cognitive benefits; however, the acute effects of flavonoid-rich (FR) drinks on cognitive function in the immediate postprandial period require examination. The objective was to investigate whether consumption of FR orange juice is associated with acute cognitive benefits over 6 h in healthy middle-aged adults. Methods: Males aged 30-65 consumed a 240-ml FR orange juice (272 mg) and a calorie-matched placebo in a randomized, double-blind, counterbalanced order on 2 days separated by a 2-week washout. Cognitive function and subjective mood were assessed at baseline (prior to drink consumption) and 2 and 6 h post consumption. The cognitive battery included eight individual cognitive tests. A standardized breakfast was consumed prior to the baseline measures, and a standardized lunch was consumed 3 h post-drink consumption. Results: Change from baseline analysis revealed that performance on tests of executive function and psychomotor speed was significantly better following the FR drink compared to the placebo. The effects of objective cognitive function were supported by significant benefits for subjective alertness following the FR drink relative to the placebo. Conclusions: These data demonstrate that consumption of FR orange juice can acutely enhance objective and subjective cognition over the course of 6 h in healthy middle-aged adults.

Purpose: The consumption of foods rich in dietary fiber and polyunsaturated fatty acids such as nuts can contribute to a healthy diet. Therefore, the formation of fermentation end-products which might exert chemopreventive effects regarding colon cancer was investigated after an in vitro simulated digestion and fermentation of nuts using human fecal microbiota. Methods: Fermentation supernatants (FS) and pellets (FP) were obtained after an in vitro fermentation of hazelnuts, almonds, macadamia, pistachios and walnuts. Short-chain fatty acids (SCFA) and bile acids (BA) in FS as well as fatty acids in FP were analyzed via gas chromatography. Malondialdehyde (MDA) levels in FS were determined photometrically. Results: Fermentation of nuts resulted in 1.9- to 2.8-fold higher concentrations of SCFA compared to the control and a shift of molar ratios toward butyrate production. In vitro fermentation resulted in the formation of vaccenic acid (C18:1 t11, 32.1 ± 3.2 % FAME; fatty acid methyl ester) and conjugated linoleic acid ( c9, t11 CLA, 2.4 ± 0.7 % FAME) exclusively in fermented walnut samples. Concentrations of secondary BA deoxycholic-/iso-deoxycholic acid (6.8-24.1-fold/4.9-10.9-fold, respectively) and levels of MDA (1.3-fold) were significantly reduced in fermented nut samples compared to the control. Conclusion: This is the first study that demonstrates the ability of the human fecal microbiota to convert polyunsaturated fatty acids from walnuts to c9, t11 CLA as a potential chemopreventive metabolite. In addition, the production of butyrate and reduction in potential carcinogens such as secondary BA and lipid peroxidation products might contribute to the protective effects of nuts regarding colon cancer development.

Purpose: The present randomized, double-blind, placebo-controlled study aimed to evaluate the effect of Zingiber officinale (ginger) consumption on some metabolic and clinical features of obesity. Methods: Eighty eligible obese women (aged 18-45 years) were randomly assigned to either ginger or placebo groups (receiving 2 g/day of ginger powder or corn starch as two 1 g tablets) for 12 weeks. Body mass index (BMI) and body composition were assessed every 4 weeks, and serum levels of leptin, adiponectin, resistin, insulin and glucose were determined before and after intervention. The homeostasis model assessment of insulin resistance (HOMA-IR) and quantitative insulin sensitivity check index (QUICKI) were also calculated. Results: Ginger consumption significantly decreased BMI, serum insulin and HOMA-IR index, along with increasing QUICKIs as compared to the placebo. Moreover, significant reductions in serum leptin, resistin and glucose were observed in both groups, especially in ginger group with nonsignificant differences between groups. The body composition and serum levels of adiponectin were not significantly changed in study groups. Conclusion: In conclusion, our findings demonstrate a minor beneficial effect of 2 g ginger powder supplementation for 12 weeks on weight loss and some metabolic features of obesity. However, given the lack of data in this area, ongoing clinical trials are needed to further explore ginger's effectiveness. [ABSTRACT FROM AUTHOR]

Purpose: Previously, anthocyanin-rich blueberry treatments have shown positive effects on cognition in both animals and human adults. However, little research has considered whether these benefits transfer to children. Here we describe an acute time-course and dose-response investigation considering whether these cognitive benefits extend to children. Methods: Using a double-blind cross-over design, on three occasions children ( n = 21; 7-10 years) consumed placebo (vehicle) or blueberry drinks containing 15 or 30 g freeze-dried wild blueberry (WBB) powder. A cognitive battery including tests of verbal memory, word recognition, response interference, response inhibition and levels of processing was performed at baseline, and 1.15, 3 and 6 h following treatment. Results: Significant WBB-related improvements included final immediate recall at 1.15 h, delayed word recognition sustained over each period, and accuracy on cognitively demanding incongruent trials in the interference task at 3 h. Importantly, across all measures, cognitive performance improved, consistent with a dose-response model, with the best performance following 30 g WBB and the worst following vehicle. Conclusion: Findings demonstrate WBB-related cognitive improvements in 7- to 10-year-old children. These effects would seem to be particularly sensitive to the cognitive demand of task.

Background: Proton-pump inhibitors (PPIs) are often prescribed to patients receiving dual antiplatelet therapy (DAPT). However, this class of medication, especially omeprazole, has been associated with a reduction in clopidogrel efficacy, leading many clinicians to substitute omeprazole with ranitidine. Objectives: Our objective was to compare the antiplatelet effect of clopidogrel before and after the addition of omeprazole or ranitidine. Methods: We measured platelet aggregability at baseline and after 1 week of clopidogrel 75 mg daily. Subjects were then randomized in a double-blinded, double-dummy fashion to omeprazole 20 mg twice daily (bid) or ranitidine 150 mg bid. We repeated aggregability tests after 1 additional week, using VerifyNow P2Y12™ (Accumetrics; San Diego, CA, USA), depicting aggregability as percent inhibition of platelet aggregation (IPA). Results: We enrolled 41 patients in the omeprazole group and 44 in the ranitidine group. IPA was significantly decreased after the addition of omeprazole to clopidogrel (from 26.3 ± 32.9 to 17.4 ± 33.1 %; p = 0.025), with no statistical significant changes observed in the ranitidine group (from 32.6 ± 28.9 to 30.1 ± 31.3 %; p = 0.310). The comparison of IPA in both groups at the end of the follow-up showed a trend toward significance ( p = 0.07, 95 % confidence interval [CI] −1.19 to 26.59); after excluding homozygous patients for 2C19*2 genotype, the comparison of IPA between the groups reached statistical significance (32.7 ± 30.8 vs. 17.7 ± 33.4 %, respectively, for ranitidine and omeprazole groups; p = 0.04). Conclusions: Unlike omeprazole, ranitidine did not influence platelet aggregability response to clopidogrel. Clinical Trial Registration: NCT01896557. [ABSTRACT FROM AUTHOR]

Purpose: We aim to examine whether honey ameliorates hepatic injury in non-alcoholic steatohepatitis (NASH) animal and cell line steatosis models. Methods: NASH was induced in female Sprague-Dawley rat by 8-week feeding with a high-fat diet. During the experiment, 5 g/kg honey was intragastrically fed daily. Rat normal hepatocyte BRL-3A cell was treated with sodium palmitate (SP) to induce steatosis in the absence or presence of honey pre-treatment or specific siRNA/overexpress plasmid of thioredoxin-interacting protein (TXNIP) or antagonist/agonist of Nod-like receptor protein 3 (NLRP3). Results: Honey significantly improved the high-fat-diet-induced hepatic injury, steatosis, fibrosis, oxidative stress, and inflammation in rats. Honey also inhibited the overexpression of TXNIP and the activation of NLRP3 inflammasome. These effects were replicated in BRL-3A cell line which showed that the down-regulation of TXNIP or inhibition of NLRP3 contributed to the suppression of NLRP3 inflammasome activation, inflammation, and re-balanced lipid metabolism. In contrast, overexpression of TXNIP or agonism of NLRP3 exacerbated the cellular damage induced by SP. Conclusion: Suppression of the TXNIP-NLRP3 inflammasome pathway may partly contribute to the amelioration of hepatic injury during the progression of NASH by honey. Targeting hepatic TXNIP-NLRP3 inflammasome pathway is a potential therapeutic way for the prevention and treatment of NASH. [ABSTRACT FROM AUTHOR]

Purpose: The consequence of the increased demand due to the population expansion has put tremendous pressure on the natural supply of fruits. Hence, there is an unprecedented growing interest in the exploration of the potentials of underutilized fruits as alternatives to the commercially available fruits. Baccaurea angulata is an underutilized fruit widely distributed in Borneo Island of Malaysia. The present study was conducted to investigate the effects of B. angulata whole fruit (WF), skin (SK) and pulp (PL) juices on malondialdehyde (MDA) levels and antioxidant enzymes in rabbits fed high-cholesterol diet. Methods: Thirty-six male rabbits of New Zealand strain were randomly assigned to six groups. Rabbits were fed either a standard pellet (group NC) or a high-cholesterol diet (groups HC, PC, WF, SK and PL). Groups WF, SK and PL were also given 1 ml/kg/day B. angulata WF, SK and PL juices, respectively. Results: Baccaurea angulata had high antioxidant activities. The administration of the various juices significantly reduced ( p < 0.05) the concentration of induced plasma MDA. The decrease in the SOD, GPx, CAT and TAC levels caused by cholesterol feeding was also ameliorated with B. angulata. Conclusion: Our results show that B. angulata fruit is beneficial in positively influencing and managing oxidative damage. [ABSTRACT FROM AUTHOR]

Purpose: Low-carbohydrate diets (LCD) are a popular dietary strategy for weight reduction. The effects of LCD on long-term outcome vary depending on type of LCD, possibly due to the fact that effects on cardiometabolic risk factors may vary with different types of LCD. Accordingly, we studied these relations. Methods: We assessed serum concentrations of high-density lipoprotein cholesterol (HDLc), low-density lipoprotein cholesterol (LDLc), high-sensitivity C-reactive protein (CRP), total cholesterol, glycated hemoglobin, and uric acid, and nutrient intakes by standardized methods in men and women ages 40-59 years from four population samples of Japanese in Japan (553 men and 544 women, combined). For people consuming usual, animal-based, and plant-based LCDs, we calculated LCD scores, based on relative level of fat, protein, and carbohydrate, by modifying the methods of Halton et al. Instead of calculating scores based on animal or vegetable fat, we used saturated fatty acids (SFA) or monounsaturated fatty acids (MUFA) + polyunsaturated fatty acids (PUFA). Results: In multivariate regression analyses with adjustment for site, age, sex, BMI, smoking, alcohol intake, physical activity, and years of education, all three LCD scores were significantly positively related to HDLc (all P < 0.001), but not to LDLc. The plant-based LCD score was significantly inversely related to log CRP (coefficient = −0.010, P = 0.018). Conclusions: All three LCD scores were significantly positively related to HDLc. The plant-based LCD score was significantly inversely related to CRP. Carbohydrate intake below 50 % of total energy with higher intakes of vegetable protein and MUFA + PUFA, and lower intakes of SFA may be favorable for reducing cardiometabolic risk factors.

Purpose: Fat randomization and interesterification change triacylglycerol (TAG) structure and its solid fat content profile. It has not been thoroughly investigated whether these changes affect lipid metabolism. Methods: Two experiments were conducted to investigate the effects of TAG structure and solid fat content on feed intake, body weight change, and serum metabolite concentrations in mice. An experiment used two fats rich in 1,2-dipalmitoyl-3-oleoylglycerol (PPO) and 1,3-dipalmitoyl-2-oleoylglycerol (POP) as comparative pair of fats to assess the effect of TAG structure since PPO and POP have the same fatty acid composition and solid fat content at 37 °C. Another experiment used a fat rich in 1-palmitoyl-2,3-dioleoylglycerol (POO) with solid fat content of zero at 37 °C and a mixture of fats that had the same general fatty acid composition and palmitic acid positional distribution, but with solid fat content of 22 % at 37 °C. This pair of fats was used to examine the effect of solid fat content on blood lipid profile. Results: After 6-week feeding, the pair of fats with different solid fat contents did not significantly affect the concentrations of total serum cholesterol, HDL cholesterol, TAG, non-esterified fatty acid (NEFA), or blood glucose. However, the PPO fat significantly reduced feed intake, body weight, and serum glucose concentration as compared to POP. Conclusion: These results suggest that the presence of solid fat at the level examined does not affect lipid metabolism and lipemia, but PPO diet significantly affects NEFA and glucose concentrations. Palmitic acid at the sn-2 position of the TAG may have significant effect on appetite, which may be mediated via the gut receptors. [ABSTRACT FROM AUTHOR]

Purpose: The optimal macronutrient composition of the diet for the management of type 2 diabetes is debated, particularly with regard to the ideal proportion of fat and carbohydrates. The aim of the study was to explore the association of different proportions of fat and carbohydrates of the diet-within the ranges recommended by different guidelines-with metabolic risk factors. Methods: We studied 1785 people with type 2 diabetes, aged 50-75, enrolled in the TOSCA.IT Study. Dietary habits were assessed using a validated food-frequency questionnaire (EPIC). Anthropometry, fasting lipids, HbA1c and C-reactive protein (CRP) were measured. Results: Increasing fat intake from <25 to ≥35 % is associated with a significant increase in LDL-cholesterol, triglycerides, HbA1c and CRP ( p < 0.05). Increasing carbohydrates intake from <45 to ≥60 % is associated with significantly lower triglycerides, HbA1c and CRP ( p < 0.05). A fiber intake ≥15 g/1000 kcal is associated with a better plasma lipids profile and lower HbA1c and CRP than lower fiber consumption. A consumption of added sugars of ≥10 % of the energy intake is associated with a more adverse plasma lipids profile and higher CRP than lower intake. Conclusions: In people with type 2 diabetes, variations in the proportion of fat and carbohydrates of the diet, within the relatively narrow ranges recommended by different nutritional guidelines, significantly impact on the metabolic profile and markers of low-grade inflammation. The data support the potential for reducing the intake of fat and added sugars, preferring complex, slowly absorbable, carbohydrates. [ABSTRACT FROM AUTHOR]

Purpose: Pomegranate fruit, Punica granatum L. (Punicaceae), and its constituents have been shown to inhibit inflammation. In this study, we aimed to assess the effects of freeze-dried pomegranate (PWE) on PGE production in IL-1β-stimulated SK-N-SH cells. Methods: An enzyme immunoassay (EIA) was used to measure prostaglandin E (PGE) production from supernatants of IL-1β-stimulated SK-N-SH cells. Expression of COX-2, phospho-IκB, and phospho-IKK proteins was evaluated, while NF-κB reporter gene assay was carried out in TNFα-stimulated HEK293 cells to determine the effect of PWE on NF-κB transactivation. Levels of BACE-1 and Aβ in SK-N-SH cells stimulated with IL-1β were measured with an in cell ELISA. Results: PWE (25-200 μg/ml) dose dependently reduced COX-2-dependent PGE production in SK-N-SH cells stimulated with IL-1β. Phosphorylation of IκB and IKK was significantly ( p < 0.001) inhibited by PWE (50-200 μg/ml). Our studies also show that PWE (50-200 μg/ml) significantly ( p < 0.01) inhibited NF-κB transactivation in TNFα-stimulated HEK293 cells. Furthermore, PWE inhibited BACE-1 and Aβ expression in SK-N-SH cells treated with IL-1β. Conclusions: Taken together, our study demonstrates that pomegranate inhibits inflammation, as well as amyloidogenesis in IL-1β-stimulated SK-N-SH cells. We propose that pomegranate is a potential nutritional strategy in slowing the progression of neurodegenerative disorders such as Alzheimer's disease. [ABSTRACT FROM AUTHOR]

Purpose: Unmetabolized folic acid (UMFA) is common in serum of elderly individuals receiving folic acid (FA)-fortified foods or supplements. We studied the effect of supplementing FA or B-complex on serum concentrations of (6 S)-5-methyltetrahydropteroylglutamate [(6S)-5-CH-HPte] and UMFA in elderly people and explored factors associated with detectable UMFA post-supplementation. Methods: This is a randomized single-blind non-controlled trial on 58 elderly people using daily 400 µg FA ( n = 31) or 400 µg FA, 10 µg cyanocob(III)alamin and 8 mg pyridoxine ( n = 27) for a median of 23 days. Main outcome includes changes in concentrations of serum (6S)-5-CH-HPte and UMFA. Results: Total homocysteine declined by a median of 1.6 ( p = 0.074) in the FA and 1.3 µmol/L ( p = 0.009) in the B-complex arms ( p = 0.66 between the arms). Serum (6S)-5-CH-HPte significantly ( p < 0.001 vs. baseline) increased by a median of 9.2 and 6.5 nmol/L in the FA and B-complex groups, respectively ( p = 0.152 between the groups). Compared to FA, B-complex reduced cystathionine and caused lower post-intervention serum UMFA, percentage of UMFA to (6S)-5-CH-HPte and prevalence of UMFA ≥ 0.21 nmol/L. Higher serum cystathionine and whole-blood folate predicted higher post-intervention serum UMFA. Conclusions: FA caused higher UMFA as compared to B-complex. Pyridoxine appears to improve folate recycling. Data on serum UMFA should be interpreted in relation to other vitamins involved in folate metabolism. Serum UMFA is suggested to play a sensory role through which the cell recognizes FA available for metabolism via dihydrofolate reductase. [ABSTRACT FROM AUTHOR]

Purpose: Vitamin B status in the body is affected by several factors including dietary supply of the antivitamin B factor, 1-amino d-proline (1ADP), which is present in flaxseed. Owing to the prevalence of moderate B deficiency in the general population, a co-occurrence of 1ADP may lead to a further deterioration of B status. To this end, we applied a nontargeted metabolomics approach to identify potential plasma lipophilic biomarkers of deleterious effect of 1ADP on moderately vitamin B-deficient rats using a high-performance liquid chromatography/quadrupole time-of-flight mass spectrometry. Methods: Twenty-four rats were fed with a semi-purified diet containing pyridoxine·HCl (PN·HCl) either 7 mg/kg diet (optimal B) or 0.7 mg/kg diet (moderate B). The rats were divided into four treatments ( n = 6), and one treatment in each B diet group was also fed ad libitum with 10 mg/kg diet of synthetic 1ADP. After 5 weeks of study, plasma was collected from the rats and lipophilic metabolites were extracted using acetonitrile as a solvent for analysis. Results: Ten potential plasma lipophilic biomarkers were identified out of >2500 detected entities, which showed significant differences between the treatments. Plasma glycocholic acid, glycoursodeoxycholic acid, murocholic acid, N-docosahexaenoyl GABA, N-arachidonoyl GABA, lumula, nandrolone and orthothymotinic acid concentrations were significantly elevated, while plasma cystamine and 3-methyleneoxindole concentrations were significantly reduced as a result of either low B status or 1ADP or their interaction. Conclusion: Changes in these metabolites revealed a potential defect in pathways linked with the biosynthesis and metabolism of bile acid components, N-acyl amino acids, analgesic androgens, anti-inflammatory and neuroprotective molecules. We also noted that the changes in these biomarkers can be alleviated by the application of adequate vitamin B. [ABSTRACT FROM AUTHOR]

Purpose: Alkylresorcinols (AR) are phenolic lipids present in the bran of wheat and rye. Plasma AR and their urinary metabolites may be suitable biomarkers of whole-grain (WG) wheat and rye consumption. The objective of this study was to examine plasma AR and urinary AR metabolites in response to WG wheat consumption. Methods: In a randomized crossover study, 19 subjects (10 males, 9 females; BMI 22.0 kg/m; age 26 years) incorporated either 3 servings (48 g) or 6 servings (96 g) of WG wheat daily into their regular diet for 1 week. Subjects completed a 2-week washout period, abstaining from all WG consumption, before each intervention. Fasting blood and 24-h urine were collected before and after each intervention. Plasma AR homologues (C19:0, C21:0, C23:0) were quantified by GC-MS after diethyl ether and solid phase extraction and derivatization. Urinary AR metabolites [3,5-dihydroxybenzoic acid and 3-(3,5-dihydroxyphenyl)-propanoic acid] were determined using HPLC with electrochemical detection after enzymatic deconjugation and ethyl acetate extraction. Results: Urinary total AR metabolites were significantly higher after 6 compared with 3 servings of WG wheat (56 vs. 32 μmol/day, P < 0.001). This dose-response relationship was independent of age, sex, energy intake, and baseline urinary AR metabolite concentration. Plasma total AR tended to be higher after 6 compared with 3 servings of WG wheat (103.0 vs. 86.9 nmol/L), but this difference was not significant ( P = 0.42). Conclusion: The results suggest that urinary AR metabolites from 24-h urine collections may be useful as biomarkers of compliance in intervention studies of WG wheat. [ABSTRACT FROM AUTHOR]

Background: Headache disorders are under-recognized and under-diagnosed. A principal factor in their suboptimal management is lack of headache-related training among health-care providers, especially in primary care. In Estonia, general practitioners (GPs) refer many headache patients to neurological specialist services, mostly unnecessarily. GPs request 'diagnostic' investigations, which are usually unhelpful and therefore wasteful. GP-made headache diagnoses are often arcane and non-specific, and treatments based on these are inappropriate. The aim of this study was to develop, implement and test an educational model intended to improve headache-related primary health care in Estonia. Methods: This was a controlled study consisting of baseline observation, intervention and follow-up observation using the same measures of effect. It involved six GPs in Põlva and the surrounding region in Southern Estonia, together with their future patients presenting consecutively with headache as their main complaint, all with their consent. The primary outcome measure was referral rate (RR) to neurological specialist services. Secondary measures included number of GP-requested investigations, GP-made headache diagnoses and how these conformed to standard terminology (ICD-10), and GP-recommended or initiated treatments. Results: RR at baseline ( n = 490) was 39.5 %, falling to 34.7 % in the post-intervention group ( n = 295) (overall reduction 4.8 %; p = 0.21). In the large subgroup of patients (88 %) for whom GPs made clearly headache-related ICD-10 diagnoses, RR fell by one fifth (from 40 to 32 %; p = 0.08), but the only diagnosis-related RR that showed a statistically significant reduction was (pericranial) myalgia (19 to 3 %; p = 0.03). There was a significant increase towards use of more specific diagnoses. Use of investigations in diagnosing headache reduced from 26 to 4 % ( p < 0.0001). Initiation of treatment by GPs increased from 58 to 81 % ( p < 0.0001). Conclusions: These were modest changes in GPs' entrenched behaviour. Nevertheless they were empirical evidence that GPs' practice in the field of headache could be improved by structured education. Furthermore, the changes were likely to be cost-saving. To our knowledge this study is the first to produce such evidence. [ABSTRACT FROM AUTHOR]

Background: Structural white matter abnormalities in pain-modulating, regions are present in migraine. Whether they are associated with pain chronification and with cognitive reserve is unclear. Methods: Prospective, cohort, six-month study of adult patients with episodic or chronic migraine, and controls. Cognitive reserve, quality of life, impact of pain on daily living, depression and anxiety were assessed. Participants underwent a diffusion-tensor MRI to establish the integrity of white matter tracts of three regions of interest (ROIs) implicated in pain modulation, emotion, cognition and resilience (anterior insula, anterior cingulate gyrus, and uncinate fasciculus). Results: Fifty-two individuals were enrolled: 19 episodic migraine patients, 18 chronic migraine patients, and 15 controls. The analysis of the fractional anisotropy in the ROIs showed that those patients with the poorest prognosis (i.e., those with chronic migraine despite therapy at six months -long-term chronic migraneurs) had a significantly lower fractional anisotropy in the right ROIs. Participants with higher cognitive reserve also had greater fractional anisotropy in the right anterior insula and both cingulate gyri. Multivariate analysis showed a significant association between cognitive reserve, migraine frequency, and fractional anisotropy in the right-sided regions of interest. Conclusions: Long-term chronic migraine patients show abnormalities in anterior white matter tracts, particularly of the right hemisphere, involved in pain modulation emotion, cognition and resilience. Robustness in these areas is associated with a higher cognitive reserve, which in turn might result in a lower tendency to migraine chronification. [ABSTRACT FROM AUTHOR]

Purpose: The aim of the study was to evaluate the vascular anti-inflammatory effects of polyphenolic extracts from two typical South Italy red wines, the specific contribution of individual polyphenols and the underlying mechanisms of action. Methods: Human endothelial cells were incubated with increasing concentrations (1-50 μg/mL) of Primitivo and Negroamaro polyphenolic extracts (PWPE and NWPE, respectively) or pure polyphenols (1-25 μmol/L), including hydroxycinnamic acids ( p-coumaric, caffeic and caftaric acids), flavonols (kaempferol, quercetin, myricetin) or stilbenes ( trans-resveratrol, trans-piceid) before stimulation with lipopolysaccharide. Through multiple assays, we analyzed the endothelial-monocyte adhesion, the endothelial expression of adhesion molecules (ICAM-1, VCAM-1 and E-Selectin), monocyte chemoattractant protein-1 (MCP-1) and macrophage colony-stimulating factor (M-CSF), as well as ROS intracellular levels and the activation of NF-κB and AP-1. Results: Both PWPE and NWPE, already at 1 μg/mL, inhibited monocyte adhesion to stimulated endothelial cells, a key event in triggering vascular inflammation. They down-regulated the expression of adhesion molecules, ICAM-1, VCAM-1, E-Selectin, as well as MCP-1 and M-CSF, at mRNA and protein levels. All polyphenols reduced intracellular ROS, and everything, except caftaric acid, inhibited the endothelial expression of adhesion molecules and MCP-1, although with different potency. Flavonols and resveratrol significantly reduced also the endothelial expression and release of M-CSF. The decrease in endothelial inflammatory gene expression was related to the inhibition of NF-κB and AP-1 activation but not to intracellular oxidative stress. Conclusions: This study showed multiple anti-inflammatory and anti-atherosclerotic properties of red wine polyphenolic extracts and indentified specific bioactive polyphenols which could counteract inflammatory diseases including atherosclerosis.

Background: Few studies have linked major dietary nutrient patterns to chronic diseases. Despite the growing evidence of associations between dietary patterns and obesity, we are aware of no study that examined the association between patterns of nutrient intake and obesity. Objective: To identify major nutrient patterns in Iranian adults and investigate their association with general and abdominal obesity. Methods: In this cross-sectional study that was conducted under the framework of the Study on the Epidemiology of Psychological Alimentary Health and Nutrition (SEPAHAN), dietary data were collected using a validated dish-based 106-item semi-quantitative food frequency questionnaire in 8691 subjects aged 18-55 years. Complete data of 6724 and 5203 adults were available for general and abdominal obesity, respectively. Data on anthropometric measures were collected through a self-administered questionnaire. General obesity was defined as body mass index ≥ 30 kg/m, and abdominal obesity as waist circumference > 102 cm for men and >88 cm for women. Daily intakes of 38 nutrients and bioactive compounds were calculated for each participant. Factor analysis, followed by a varimax rotation, was applied to derive major nutrient patterns. Results: Three major nutrient patterns were identified: (1) The first pattern was high in fatty acids (including saturated, monounsaturated and polyunsaturated fatty acids), cholesterol, vitamin B, vitamin E, zinc, choline, protein, pyridoxine, phosphorus and pantothenic acid; (2) the second pattern was high in thiamine, betaine, starch, folate, iron, selenium, niacin, calcium, and manganese; and (3) the third pattern was high in glucose, fructose, sucrose, vitamin C, potassium, total dietary fiber, copper and vitamin K. Men in the highest quintile of the second pattern were less likely to be generally obese in the fully adjusted model [odds ratio (OR) 0.39, 95 % confidence interval (CI) 0.20-0.76]. After adjustment for potential confounders, a significant positive association was observed between the third pattern and general obesity among men (OR 1.77, 95 % CI 1.04-3.04), but not women (OR 1.18, 95 % CI 0.74-1.88). No overall association was seen between patterns of nutrient intake and abdominal obesity in both genders. Conclusion: Major nutrient patterns were significantly associated with general, but not abdominal obesity among male participants of the SEPAHAN study. Further studies in other populations, along with future prospective studies, are required to confirm these findings. [ABSTRACT FROM AUTHOR]

Purpose: Controversy exists regarding whether increasing dairy intake without energy restriction would lead to weight loss. We aimed to compare the potential weight-reducing effects of kefir drink (a probiotic dairy product) and milk in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. Methods: One hundred and forty-four subjects were assessed for eligibility in this single-center, multi-arm, parallel-group, randomized controlled trial. Of these, seventy-five eligible women aged 25-45 years were randomly assigned to three groups, labeled as control, milk, and kefir, to receive an outpatient dietary regimen for 8 weeks. Subjects in the control group received a diet providing a maintenance level of energy intake, containing 2 servings/day of low-fat dairy products, while those in the milk and kefir groups received a weight maintenance diet, containing 2 additional servings/day (a total of 4 servings/day) of dairy products from low-fat milk or commercial kefir drink, respectively. Anthropometric outcomes including weight, body mass index (BMI), and waist circumference (WC) were measured every 2 weeks. Results: Fifty-eight subjects completed the study. Using analysis of covariance models in the intention-to-treat population ( n = 75), we found that at 8 weeks, subjects in the kefir and milk groups had significantly greater reductions in weight, BMI, and WC compared to those in the control group (all p < 0.01). However, no such significant differences were found between the kefir and milk groups. Conclusions: Kefir drink leads to a similar weight loss, compared with milk, in a dairy-rich non-energy-restricted diet in overweight or obese premenopausal women. However, further studies are warranted. [ABSTRACT FROM AUTHOR]

Purpose: Current experimental studies support a beneficial role of extra-virgin olive oil (EVOO) in several inflammatory diseases. The present study was designed to evaluate the effects of dietary EVOO on type II collagen-induced arthritis (CIA) in mice. Methods: DBA-1/J mice were randomized in four experimental groups (10 or 15 animals per group): (1) Sham sunflower diet (SO-Sham), (2) CIA sunflower diet (SO-CIA), (3) Sham EVOO diet (EVOO-Sham) and (4) CIA EVOO diet (EVOO-CIA) group. After 6 weeks, arthritis was induced by type II collagen. Mice were sacrified 42 days after first immunization. In addition to macroscopic and histological analyses, serum levels of cartilage olimeric matrix protein (COMP), metalloproteinase-3 (MMP-3) and pro-inflammatory cytokines levels were evaluated by ELISA. The expressions of heme oxygenase-1 (HO-1), nuclear factor E2-related factor 2 (Nrf2), mitogen-activated protein kinases (MAPKs), Janus kinase-signal transducer and activator of transcription (JAK/STAT) and nuclear transcription factor-kappa B (NF-κB) pathways were studied by western blotting. Results: EVOO diet significantly reduced joint edema and cartilage destruction, preventing the arthritis development. Dietary EVOO significantly decreased serum COMP and MMP-3 levels, as well as, the pro-inflammatory cytokines levels (TNF-α, IL-1β and IL-17). Moreover, the activation of JAK/STAT, MAPKs and NF-κB pathways was drastically ameliorated. According to Nrf2 and HO-1, the protein expressions were up-regulated in those mice fed with EVOO. Conclusion: These results support the interest of EVOO as a beneficial functional food to prevent the development of the rheumatoid arthritis (RA). [ABSTRACT FROM AUTHOR]

Purpose: The aim of this study was to analyze whether the combination of resveratrol and quercetin showed additive or synergic effects on body fat accumulation and triacylglycerol metabolism in adipose tissue from rats fed an obesogenic diet. Methods: Rats were divided into four dietary groups: a control group and three groups each treated with either resveratrol (15 mg/kg/day; RSV), quercetin (30 mg/kg/day; Q), or both (15 mg resveratrol/kg/day and 30 mg quercetin/kg/day; RSV + Q) for 6 weeks. White adipose tissues from several anatomical locations were dissected. Serum parameters were analyzed by using commercial kits. The activities of fatty acid synthase and heparin-releasable lipoprotein lipase (HR-LPL) were measured using spectrophotometric and fluorimetric methods, and protein expression of acetyl-CoA carboxylase (ACC), adipose tissue triglyceride lipase (ATGL), and hormone-sensitive lipase (HSL) by western blot. Results: The administration of either resveratrol or quercetin separately did not induce significant reductions in adipose tissue weights. By contrast, the combination of both molecules led to a significant reduction in all the fat depots analyzed. The percentage of reduction in each tissue was greater than the calculated additive effect. HR-LPL activity was reduced in RSV and RSV + Q groups. The activity of HSL was not modified. By contrast, ACC was inhibited and ATGL increased only by the combination of both polyphenols. Conclusion: The results obtained demonstrate a synergistic effect between resveratrol and quercetin and suggest that when these molecules are combined, a great number of metabolic pathways involved in adipose tissue triacylglycerol accumulation are affected.

Purpose: Dextran sodium sulphate (DSS)-induced colitis is a widely used model for inflammatory bowel disease. However, various factors including nutrition may affect the development of this colitis. This study aimed to compare and characterize the impact of purified and non-purified basal diets on the development of DSS-induced colitis in the rat. Methods: Wistar rats were fed a non-purified or a semi-synthetic purified diet for 21 days. Colitis was then induced in half of the rats by administration of DSS in drinking water (4 % w/v) during the last 7 days of experimentation. At the end of the experimental period, colon sections were taken for histopathological examination, determination of various markers of inflammation (myeloperoxidase: MPO, cytokines) and oxidative stress (superoxide dismutase: SOD, catalase: CAT, glutathione peroxidase: GPx and glutathione reductase: GRed activities), and evaluation of the expression of various genes implicated in this disorder. Results: DSS ingestion induced a more marked colitis in animals receiving the purified diet, as reflected by higher histological score and increased MPO activity. A significant decrease in SOD and CAT activities was also observed in rats fed the purified diet. Also, in these animals, administration of DSS induced a significant increase in interleukin (IL)-1α, IL-1β and IL-6. In addition, various genes implicated in inflammation were over-expressed after ingestion of DSS by rats fed the purified diet. Conclusions: These results show that a purified diet promotes the onset of a more severe induced colitis than a non-purified one, highlighting the influence of basal diet in colitis development.

Purpose: Muffins made with wheat flour are a popular snack consumed in western and emerging countries. This study aimed to examine the content of amylose, glycemic response (GR) and glycemic index (GI) of muffins baked with refined wheat and rice flours, as well as wholegrain corn, oat and barley flours. Methods: This study adopted a randomized, controlled, crossover, non-blind design. Twelve healthy participants consumed wheat, rice, corn, oat and barley muffins once and the reference glucose solution three times in a random order on non-consecutive day. Capillary blood samples were taken every 15 min in the first 60 min and every 30 min for the remaining 60 min for blood glucose analysis. The Megazyme amylose/amylopectin assay procedure was employed to measure amylose content. Results: The GR elicited from the consumption of wheat, rice and corn muffins was comparable between these samples but significantly greater when compared with oat and barley muffins. Consumption of wholegrain muffins, apart from corn muffin, blunted postprandial GR when compared with muffins baked with refined cereal flours. Muffins baked with wheat, rice, corn, oat and barley flours gave rise to GI values of 74, 79, 74, 53 and 55, respectively. The content of amylose was significantly higher in corn, oat and barley muffins than wheat and rice muffins. Conclusions: The greater content of amylose and fibre may play a part in the reduced glycemic potency of oat and barley muffins. Wheat flour can be substituted with oat and barley flours for healthier muffins and other bakery products. [ABSTRACT FROM AUTHOR]

Purpose: In Caucasian women, research has shown that energy balance and taste preference change throughout the menstrual cycle. However, the contributory role of the menstrual cycle to obesity and insulin resistance among Asian women remains unclear. We investigate the impact of the menstrual cycle on energy balance and taste preference in Singaporean Chinese females. Methods: Thirty-one healthy young Chinese female subjects with regular menstrual cycles were recruited. Anthropometrics, body composition, energy intake, resting metabolic rate, premenstrual syndrome (PMS) severity and taste preference to sucrose were assessed during three phases (menses, follicular and luteal), over one ( N = 18) to two ( N = 13) menstrual cycles. Results: For all subjects ( N = 31), we found significant reductions in energy, fat intake ( p < 0.05) and taste preference for sucrose ( p < 0.05) in the luteal phase compared to early follicular phase as far as Cycle 1 is concerned. No significant differences were observed for carbohydrate and protein intake as well as PMS score. In those evaluated for two full cycles ( N = 13), we found that taste preference for sucrose and PMS score were significantly higher in the menstrual phase in Cycle 2 ( p < 0.05). No significant differences were observed in energy and macronutrient intake throughout Cycle 2. RMR was similar across the three phases. However, non-significant cyclic variations were noted within and between the cycles. Conclusion: Cyclic variations in energy intake and expenditure contributed by sensory and behavioural changes occur during the menstrual cycle. Whether this contributes to cyclic weight gain is speculative and remains to be proven. Further research in non-Caucasians spanning more than one menstrual cycle is needed to establish the impact of the menstrual cycle on taste preference and energy balance. [ABSTRACT FROM AUTHOR]

Purpose: Currently, obesity has become a worldwide health problem. Adipocyte differentiation is closely associated with the onset of obesity. Our previous studies suggested that persimmon tannin might be a potent anti-adipogenic dietary bioactive compound. However, the mechanism of persimmon tannin on adipocyte differentiation is still unknown. The purpose of this study was to investigate the effect of persimmon tannin on adipogenic differentiation in 3T3-L1 preadipocytes and the underlying mechanisms. Methods: Adipogenic differentiation was induced by cocktail in the presence or absence of persimmon tannin. Intracellular lipid accumulation was determined by Oil red O staining and enzymatic colorimetric methods. Gene expression and protein levels were measured by real time RT-PCR and Western blot. Results: Persimmon tannin inhibited intracellular lipid accumulation markedly, and the inhibitory effect was largely limited to the early stage of adipocyte differentiation. Persimmon tannin suppressed the expression of C/EBPα and peroxisome proliferator-activated receptor-γ (PPARγ), significantly. Furthermore, genes related to lipogenesis, such as sterol regulatory element-binding protein 1, were down-regulated by persimmon tannin. In addition, adipocyte fatty acid binding protein (aP2), which is a target gene of PPARγ, was suppressed by persimmon tannin notably. Correspondingly, the expression of miR-27a and miR-27b were up-regulated by persimmon tannin from Day 2 to Day 8 significantly. Conclusion: Persimmon tannin inhibited adipocyte differentiation through regulation of PPARγ, C/EBPα and miR-27 in early stage of adipogenesis. [ABSTRACT FROM AUTHOR]
