Evaluating Dietary Patterns in Women from Southern Italy and Western Mexico

Traditional diets are known to be beneficial; however, both Italian and Mexican populations are gradually moving away from the Mediterranean and traditional Mexican diets. Since women play a key role in safeguarding dietary traditions and may reflect population dietary changes, we aimed to identify Italian and Mexican women’s current dietary patterns (DPs) and characterize their nutrient content. Cross-sectional analyses were separately conducted on two convenience samples of 811 women from Southern Italy and 215 women from Western Mexico. Food frequency questionnaires, 24 h recalls, and a principal component analysis (PCA) approach were used to derive a posteriori DPs. In Italian women, the first DP was characterized by the consumption of legumes, vegetables, and fish (8.8% of the total variance), while the second DP was characterized by snack foods, processed meats, and non-olive oils. In Mexican women, the first DP was characterized by the consumption of meats and processed foods (12.6% of the total variance), while the second DP by fruits, vegetables, and whole grains. In both populations, adhering to the DPs rich in healthy foods (i.e., fruits, vegetables, legumes, and fish) was associated with a higher quality of diet in terms on nutrient content. However, adherence to the Western-type DPs was more common among women of younger age (p < 0.035). Thus, more extraordinary efforts are needed in promoting each country’s traditional healthy diet, especially among the new generations.     

S2k Guidelines for the diagnosis and treatment of chronic pruritus – update – short version

Associated with a host of different diseases, pruritus is a cardinal symptom that poses an interdisciplinary diagnostic and therapeutic challenge. Over time, that symptom may progress independently of the initial cause, thus losing its function as a warning sign and turning into a clinically relevant disease of its own. In Germany, approximately 13.5 % of the general population are affected by chronic pruritus, with an incidence of 7 %. All forms of chronic pruritus require targeted treatment consisting of (a) diagnosis and management of the underlying disease, (b) dermatological treatment of primary or secondary (for example, dry skin, scratch lesions) symptoms, (c) symptomatic antipruritic treatment, and (d) psychological/psychotherapeutic treatment in case of an underlying or associated psychological or psychosomatic condition. Medical care of patients with chronic pruritus should therefore include an interdisciplinary approach, in particular with respect to diagnosis and therapy of the underlying disease as well as in terms of the management of treatment and adverse events. The objective of the present interdisciplinary guidelines is to define and standardize diagnostic and therapeutic procedures in patients with chronic pruritus. This is a short version of the current S2 guidelines on chronic pruritus. The long version may be found at www.awmf.org .     

Involvement of NRN1 gene in schizophrenia-spectrum and bipolar disorders and its impact on age at onset and cognitive functioning

Objectives Neuritin 1 gene (NRN1) is involved in neurodevelopment processes and synaptic plasticity and its expression is regulated by brain-derived neurotrophic factor (BDNF). We aimed to investigate the association of NRN1 with schizophrenia-spectrum disorders (SSD) and bipolar disorders (BPD), to explore its role in age at onset and cognitive functioning, and to test the epistasis between NRN1 and BDNF. Methods The study was developed in a sample of 954 SSD/BPD patients and 668 healthy subjects. Genotyping analyses included 11 SNPs in NRN1 and one functional SNP in BDNF. Results The frequency of the haplotype C-C (rs645649–rs582262) was significantly increased in patients compared to controls (P?=?0.0043), while the haplotype T-C-C-T-C-A (rs3763180–rs10484320–rs4960155–rs9379002–rs9405890–rs1475157) was more frequent in controls (P?=?3.1?×?10^?5). The variability at NRN1 was nominally related to changes in age at onset and to differences in intelligence quotient, in SSD patients. Epistasis between NRN1 and BDNF was significantly associated with the risk for SSD/BPD (P?=?0.005). Conclusions Results suggest that: (i) NRN1 variability is a shared risk factor for both SSD and BPD, (ii) NRN1 may have a selective impact on age at onset and intelligence in SSD, and (iii) the role of NRN1 seems to be not independent of BDNF.     

Chemokine expression in hepatocellular carcinoma versus colorectal liver metastases

INTRODUCTION Chemokines represent a family of small chemotactic cytokines, initially identified as mediators of leucocyte trafficking and homing. In the last few years, chemokines have been shown to participate also in tumor growth and the lymphatic and e…
