  abstract  = {Background The role of a healthy dietary pattern in the prevention of abdominal aortic aneurysms (AAA) is unknown. We aimed to evaluate the relationship between adherence to a Dietary Approaches To Stop Hypertension-style dietary pattern and the risk of incident AAAs. Methods and Results Dietary intake was assessed via a 66-item food frequency questionnaire at baseline (1987-1989) and at visit 3 (1993-1995) in 13 496 participants enrolled in the ARIC (Atherosclerosis Risk in Communities) study without clinical AAA (mean age, 54 years). A dietary scoring index based on food times was constructed to assess self-reported adherence to a dietary approaches to stop hypertension-style dietary pattern. Participants were followed for incident clinical AAAs using hospital discharge diagnoses, Medicare inpatient and outpatient diagnoses, or death certificates through December 31, 2011. Cox proportional hazards models with covariate adjustment were used to estimate hazard ratios with 95\% confidence intervals. During a median follow-up of 23 years, there were 517 incident AAA cases. Individuals with a Dietary Approaches To Stop Hypertension-style diet score in the highest quintile had a 40\% lower risk of hospitalization for AAA than those in the lowest quintile (hazard ratio\(_{Q5}\) vs \(_{Q1}\): 0.60; 95\% confidence intervals: 0.44, 0.83; P\(_{trend}\)=0.002). In detailed analyses, higher consumption of fruits, vegetables, whole grains, low-fat dairy, and nuts and legumes was related to a lower risk for AAA. Conclusions Greater adherence to a Dietary Approaches To Stop Hypertension-style dietary pattern was associated with lower risk for AAA. Higher consumption of fruits, vegetables, whole grains, low-fat dairy as well as nuts and legumes may help to decrease the burden of AAAs.},

  abstract  = {Nonalcoholic fatty liver disease, induced by a Western diet (WD), evokes central and peripheral inflammation that is accompanied by altered emotionality. These changes can be associated with abnormalities in social behaviour, hippocampus-dependent cognitive functions, and metabolism. Female C57BL/6J mice were fed with a regular chow or with a WD containing 0.2\% of cholesterol and 21\% of saturated fat for three weeks. WD-treated mice exhibited increased social avoidance, crawl-over and digging behaviours, decreased body-body contacts, and hyperlocomotion. The WD-fed group also displayed deficits in hippocampal-dependent performance such as contextual memory in a fear conditioning and pellet displacement paradigms. A reduction in glucose tolerance and elevated levels of serum cholesterol and leptin were also associated with the WD. The peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PPARGC1a) mRNA, a marker of mitochondrial activity, was decreased in the prefrontal cortex, hippocampus, hypothalamus, and dorsal raphe, suggesting suppressed brain mitochondrial functions, but not in the liver. This is the first report to show that a WD can profoundly suppress social interactions and induce dominant-like behaviours in na{\"i}ve adult mice. The spectrum of behaviours that were found to be induced are reminiscent of symptoms associated with autism, and, if paralleled in humans, suggest that a WD might exacerbate autism spectrum disorder.},

  abstract  = {Dendritic cells (DCs) can be sub-divided into various subsets that play specialized roles in priming of adaptive immune responses. Atherosclerosis is regarded as a chronic inflammatory disease of the vessel wall and DCs can be found in non-inflamed and diseased arteries. We here performed a systematic analyses of DCs subsets during atherogenesis. Our data indicate that distinct DC subsets can be localized in the vessel wall. In C57BL/6 and low density lipoprotein receptor-deficient (Ldlr-/-) mice, CD11c+ MHCII+ DCs could be discriminated into CD103- CD11b+F4/80+, CD11b+F4/80- and CD11b-F4/80- DCs and CD103+ CD11b-F4/80- DCs. Except for CD103- CD11b- F4/80- DCs, these subsets expanded in high fat diet-fed Ldlr-/- mice. Signal-regulatory protein (Sirp)-α was detected on aortic macrophages, CD11b+ DCs, and partially on CD103- CD11b- F4/80- but not on CD103+ DCs. Notably, in FMS-like tyrosine kinase 3-ligand-deficient (Flt3l-/-) mice, a specific loss of CD103+ DCs but also CD103- CD11b+ F4/80- DCs was evidenced. Aortic CD103+ and CD11b+ F4/80- CD103- DCs may thus belong to conventional rather than monocyte-derived DCs, given their dependence on Flt3L-signalling. CD64, postulated to distinguish macrophages from DCs, could not be detected on DC subsets under physiological conditions, but appeared in a fraction of CD103- CD11b+ F4/80- and CD11b+ F4/80+ cells in atherosclerotic Ldlr-/- mice. The emergence of CD64 expression in atherosclerosis may indicate that CD11b+ F4/80- DCs similar to CD11b+ F4/80+ DCs are at least in part derived from immigrated monocytes during atherosclerotic lesion formation. Our data advance our knowledge about the presence of distinct DC subsets and their accumulation characteristics in atherosclerosis, and may help to assist in future studies aiming at specific DC-based therapeutic strategies for the treatment of chronic vascular inflammation.},

  abstract  = {Background: Increased lipoprotein(a) [Lp(a)] levels are associated with atherosclerotic cardiovascular disease. Studies of dietary interventions on changes in Lp(a) are sparse. We aimed to compare the effects of three healthy dietary interventions differing in macronutrient content on Lp(a) concentration. Methods: Secondary analysis of a randomized, 3-period crossover feeding study including 155 (89 blacks; 66 whites) individuals. Participants were given DASHtype healthy diets rich in carbohydrates [Carb], in protein [Prot] or in unsaturated fat [Unsat Fat] for 6 weeks each. Plasma Lp(a) concentration was assessed at baseline and after each diet. Results: Compared to baseline, all interventional diets increased mean Lp(a) by 2 to 5 mg/dl. Unsat Fat increased Lp(a) less than Prot with a difference of 1.0 mg/dl (95\% CI, -0.5, 2.5; p=0.196) in whites and 3.7 mg/dl (95\% CI, 2.4, 5.0; p<0.001) in blacks (p-value between races=0.008); Unsat Fat increased Lp(a) less than Carb with a difference of 20.6 mg/dl, 95\% CI, -2.1, 0.9; p=0.441) in whites and 21.5 mg/dl (95\% CI, -0.2, -2.8; p=0.021) in blacks (p-value between races=0.354). Prot increased Lp(a) more than Carb with a difference of 0.4 mg/dl (95\% CI, -1.1, 1.9; p=0.597) in whites and 2.2 mg/dl (95\%CI, 0.9, 3.5; p=0.001) in blacks (p-value between races=0.082). Conclusion: Diets high in unsaturated fat increased Lp(a) levels less than diets rich in carbohydrate or protein with greater changes in blacks than whites. Our results suggest that substitutions with dietary mono- and polyunsaturated fatty acids in healthy diets may be preferable over protein or carbohydrates with regards to Lp(a).},

The relationship between a healthy lifestyle and CHIP is unknown. Methods and Results This analysis included 8709 postmenopausal women (mean age, 66.5 years) enrolled in the WHI (Women's Health Initiative), free of cancer or cardiovascular disease, with deep-coverage whole genome sequencing data available. Information on lifestyle factors (body mass index, smoking, physical activity, and diet quality) was obtained, and a healthy lifestyle score was created on the basis of healthy criteria met (0 point [least healthy] to 4 points [most healthy]). CHIP was derived on the basis of a prespecified list of leukemogenic driver mutations. The prevalence of CHIP was 8.6\%. A higher healthy lifestyle score was not associated with CHIP (multivariable-adjusted odds ratio [OR] [95\% CI], 0.99 [0.80-1.23] and 1.13 [0.93-1.37]) for the upper (3 or 4 points) and middle category (2 points), respectively, versus referent (0 or 1 point). Across score components, a normal and overweight body mass index compared with obese was significantly associated with a lower odds for CHIP (OR, 0.71 [95\% CI, 0.57-0.88] and 0.83 [95\% CI, 0.68-1.01], respectively; P-trend 0.0015). Having never smoked compared with being a current smoker tended to be associated with lower odds for CHIP. Conclusions A healthy lifestyle, based on a composite score, was not related to CHIP among postmenopausal women. However, across individual lifestyle factors, having a normal body mass index was strongly associated with a lower prevalence of CHIP. These findings support the idea that certain healthy lifestyle factors are associated with a lower frequency of CHIP.},

  abstract  = {The diet contains a large number of constituents which can be nitrosated in the gastrointestinal tract (especially in the stomach) to potentially carcinogenic nitroso compounds (NOC). The nitrosation of food mixtures has been investigated with a number of assays, such as chemical analysis or detection of alkylating potential, mutagenicity and carcinogenicity. Relatively good information is available on the formation of stable nitrosamines using high nitrite concentrations. Little is known, however, about the formation of chemically unstable NOC at low nitrite concentration and their genotoxicity in target cells. A comparison of the precursor classes, alkylamines, aromatic amines, amino acids, amides and peptides, ureas and guanidines, reveals a vast range, both with respect to daily intake (105-fold) and nitrosation rate (104-fold both for 1st and 2nd order nitrite dependence). A total span of 108 results for the relative yield of NOC in the stomach. The endogenous NOC burden from dietary ureas and aromatic amines may represent as large a hazard as the intake of preformed NOC. Recent evidence also indicates that heterocyclic amines and phenols must be considered and that the half-life of nitrosated a-amino acids can be much longer than that of nitrosated primary alkylamines. In these classes, more information should be collected on dietary concentrations, on the nitrosation under realistic conditions and on the genotoxicity in stomach lining cells. Within a chemical precursor class, a wide range is seen with respect to alkylating potency. It cannot, therefore, be excluded that individual precursors within the top ranking classes might become more important than single preformed NOC. Not considered in the above analysis but probably just as important for a risk evaluation in a population is the knowledge of the nitrosation conditions and target cell susceptibility in individuals.},

  abstract  = {Welcome to the inaugural meeting of the International Society for Nutritional Psychiatry Research (ISNPR). It is a great pleasure to have the opportunity to join with colleagues working in this new and exciting field of research. Although there has long been interest in the links between nutritional deficiencies and psychiatric illness, as well as interest in the role of food allergies in such illnesses, the last five years has seen a significant and notable growth in this nascent field of research, with an accompanying impact on the viewpoints and practices of scientists and clinicians working in mental health. In my particular field of interest - that of the role of overall dietary quality in the common mental disorders, depression and anxiety - there has been an exponential growth in the literature since the end of 2009. It is exciting and gratifying to see concordant results from across the globe, in young children and adolescents through to older adults, and from countries as diverse as Norway and Taiwan. The study of the efficacy of nutritional interventions in psychiatric illness is also developing rapidly, with high quality randomised controlled trials now being conducted in multiple settings and with outcomes that include cognition as well as depression, bipolar disorder, schizophrenia and anxiety disorders. Another important development in this field is the rapidly growing recognition that nutrition is of central importance in the risk for cognitive decline and dementia. As this new recognition filters through to clinical researchers, I look forward to seeing new interventions in this area. Another area of research with significant interest and activity grows from the understanding of the centrality of physical health to mental health and vice versa. There are many nutrition researchers, dietitians and other health practitioners working to address the physical health of patients with mental illness; acting on the recognition that physical and mental health are closely related and mutually reinforcing. There is no doubt that the formation of an international society is timely; we now have the opportunity to join forces to share knowledge and build important collaborations. Building capacity in this field by sharing our knowledge with students and early career researchers will be another important activity of our society, as will building the credibility of nutritional psychiatry research through a clear understanding and implementation of best practice scientific methodology. I welcome each of you to extend the invitation to join our new ISNPR to colleagues and students in your networks. I would also encourage you to contribute to the discussions and sharing of knowledge by contributing short pieces to our newsletter, which will be disseminated by the end of this year. For those who are unable to attend this year's meeting, we hope that 2014 may present a possibility for attendance. Our aim is conduct our first Annual General Meeting before the end of July 2013 via teleconference and I welcome agenda items from those interested.

While for a long time, a diet as low in nitrates as possible was advocated on the basis of epidemiological data suggesting a cancer-promoting effect of nitrate-rich diets, more recent findings show that dietary nitrate, after its conversion to nitrite by nitrate-reducing bacteria of the oral microbiota, is an indispensable alternative source for the formation of nitric oxide (NO), which comprises a key element in the physiology of a variety of central body functions such as blood pressure control, defense against invading bacteria and maintenance of a eubiotic microbiota in the gut and oral cavity. This compact narrative review aims to present the evidence supported by clinical and in vitro studies on the ambivalent nature of dietary nitrates for general and oral health and to explain how the targeted adjuvant use of nitrate-rich diets could open new opportunities for a more cause-related control of caries and periodontal disease.},

Here, we investigated the role of the co-inhibitory receptor programmed cell death-1 (PD-1) in T cell activation and CD4(+) T cell polarization towards pro-atherogenic or atheroprotective responses in mice. Mice deficient for both low density lipoprotein receptor and PD-1 (Ldlr(-/-)Pd1(-/-)) displayed striking increases in systemic CD4(+) and CD8(+) T cell activation after 9 weeks of high fat diet feeding, associated with an expansion of both pro-atherogenic IFNγ-secreting T helper 1 cells and atheroprotective Foxp3+ Tregs. Importantly, PD-1 deficiency did not affect Treg suppressive function in vitro. Notably, PD-1 deficiency exacerbated atherosclerotic lesion growth and entailed a massive infiltration of T cells in atherosclerotic lesions. In addition, aggravated hypercholesterolemia was observed in Ldlr(-/-)Pd1(-/-) mice. In conclusion, we here demonstrate that although disruption of PD-1 signaling enhances both pro- and anti-atherogenic T cell responses in Ldlr(-/-) mice, pro-inflammatory T cell activation prevails and enhances dyslipidemia, vascular inflammation and atherosclerosis.},

  abstract  = {Honeybees are among the few animals that rely on eusociality to survive. While the task of queen and drones is only reproduction, all other tasks are accomplished by sterile female worker bees. Different tasks are mostly divided by worker bees of different ages (temporal polyethism). Young honeybees perform tasks inside the hive like cleaning and nursing. Older honeybees work at the periphery of the nest and fulfill tasks like guarding the hive entrance. The oldest honeybees eventually leave the hive to forage for resources until they die. However, uncontrollable circumstances might force the colony to adapt or perish. For example, the introduced Varroa destructor mite or the deformed wing virus might erase a lot of in-hive bees. On the other hand, environmental events might kill a lot of foragers, leaving the colony with no new food intake. Therefore, adaptability of task allocation must be a priority for a honeybee colony. In my dissertation, I employed a wide range of behavioral, molecular biological and analytical techniques to unravel the underlying molecular and physiological mechanisms of the honeybee division of labor, especially in conjunction with honeybee malnourishment. The genes AmOARα1, AmTAR1, Amfor and vitellogenin have long been implied to be important for the transition from in-hive tasks to foraging. I have studied in detail expression of all of these genes during the transition from nursing to foraging to understand how their expression patterns change during this important phase of life. My focus lay on gene expression in the honeybee brain and fat body. I found an increase in the AmOARα1 and the Amforα mRNA expression with the transition from in-hive tasks to foraging and a decrease in expression of the other genes in both tissues. Interestingly, I found the opposite pattern of the AmOARα1 and AmTAR1 mRNA expression in the honeybee fat body during orientation flights. Furthermore, I closely observed juvenile hormone titers and triglyceride levels during this crucial time. Juvenile hormone titers increased with the transition from in-hive tasks to foraging and triglyceride levels decreased. Furthermore, in-hive bees and foragers also differ on a behavioral and physiological level. For example, foragers are more responsive towards light and sucrose. I proposed that modulation via biogenic amines, especially via octopamine and tyramine, can increase or decrease the responsiveness of honeybees. For that purpose, in-hive bees and foragers were injected with both biogenic amines and the receptor response was quantified 1 using electroretinography. In addition, I studied the behavioral response of the bees to light using a phototaxis assay. Injecting octopamine increased the receptor response and tyramine decreased it. Also, both groups of honeybees showed an increased phototactic response when injected with octopamine and a decreased response when injected with tyramine, independent of locomotion. Additionally, nutrition has long been implied to be a driver for division of labor. Undernourished honeybees are known to speed up their transition to foragers, possibly to cope with the missing resources. Furthermore, larval undernourishment has also been implied to speed up the transition from in-hive bees to foragers, due to increasing levels of juvenile hormone titers in adult honeybees after larval starvation. Therefore, I reared honeybees in-vitro to compare the hatched adult bees of starved and overfed larvae to bees reared under the standard in-vitro rearing diet. However, first I had to investigate whether the in-vitro rearing method affects adult honeybees. I showed effects of in-vitro rearing on behavior, with in-vitro reared honeybees foraging earlier and for a shorter time than hive reared honeybees. Yet, nursing behavior was unaffected. Afterwards, I investigated the effects of different larval diets on adult honeybee workers. I found no effects of malnourishment on behavioral or physiological factors besides a difference in weight. Honeybee weight increased with increasing amounts of larval food, but the effect seemed to vanish after a week. These results show the complexity and adaptability of the honeybee division of labor. They show the importance of the biogenic amines octopamine and tyramine and of the corresponding receptors AmOARα1 and AmTAR1 in modulating the transition from inhive bees to foragers. Furthermore, they show that in-vitro rearing has no effects on nursing behavior, but that it speeds up the transition from nursing to foraging, showing strong similarities to effects of larval pollen undernourishment. However, larval malnourishment showed almost no effects on honeybee task allocation or physiology. It seems that larval malnourishment can be easily compensated during the early lifetime of adult honeybees.},
