Next Generation Probiotics for Neutralizing Obesogenic Effects: Taxa Culturing Searching Strategies.

The combination of diet, lifestyle, and the exposure to food obesogens categorized into "microbiota disrupting chemicals" (MDC) could determine obesogenic-related dysbiosis and modify the microbiota diversity that impacts on individual health-disease balances, inducing altered pathogenesis phenotypes. Specific, complementary, and combined treatments are needed to face these altered microbial patterns and the specific misbalances triggered. In this sense, searching for next-generation beneficial microbes or next-generation probiotics (NGP) by microbiota culturing, and focusing on their demonstrated, extensive scope and well-defined functions could contribute to counteracting and repairing the effects of obesogens. Therefore, this review presents a perspective through compiling information and key strategies for directed searching and culturing of NGP that could be administered for obesity and endocrine-related dysbiosis by (i) observing the differential abundance of specific microbiota taxa in obesity-related patients and analyzing their functional roles, (ii) developing microbiota-directed strategies for culturing these taxa groups, and (iii) applying the successful compiled criteria from recent NGP clinical studies. New isolated or cultivable microorganisms from healthy gut microbiota specifically related to obesogens' neutralization effects might be used as an NGP single strain or in consortia, both presenting functions and the ability to palliate metabolic-related disorders. Identification of holistic approaches for searching and using potential NGP, key aspects, the bias, gaps, and proposals of solutions are also considered in this review.

Patient Discomfort in Relation to Thyroid Nodule Fine-Needle Aspiration (FNA) Performed with or without Parenteral and/or Topical Anesthetic.

OBJECTIVE: There is much reported variation in the impact of local anesthesia on thyroid fine-needle aspiration (FNA) related discomfort. We compare patients undergoing thyroid FNA with subcutaneous injection or topical anesthetic to no anesthetic. METHODS: We conducted a retrospective review of 585 sequential ultrasound guided thyroid FNA procedures in Mayo Clinic. Group 1 (n = 200), no anesthetic; Group 2 (n = 185), subcutaneous injection anesthetic; and Group 3 (n = 200), topical anesthetic. Patient demographics, number of FNA passes, needle gauge, and cytopathology were recorded plus a discomfort score (0 to 10) before and immediately post procedure in all 3 groups and peak discomfort during the FNA in Groups 1 and 2. RESULTS: There were no differences among the 3 groups in age, sex, FNA sufficiency rate, cytopathology, and FNA passes number. There was no significant difference between Groups 1 and 2 in peak discomfort score during the FNA: 0 (45%, 42.2%), 1 to 2 (19%, 24.9%), 3 to 5 (23.5%, 20.5%), 6 to 8 (9.5%, 10.8%), 9 to 10 (3%, 1.6%), respectively. Discomfort score post procedure: 0 (78.5%, 77.8%, 53.5%), 1 to 2 (13%, 13%, 36.5%), 3 to 5 (7%, 7%, 9%), 6 to 8 (1.5%, 2.2%, 1%), 9 to 10 (0%, 0%, 0%) for groups 1, 2, and 3, respectively. There were no significant differences among the 3 groups for a discomfort score ≥3. CONCLUSION: FNA associated patient discomfort was comparable during and after the procedure regardless of the use of anesthetic or the type utilized. Approximately 90% of patients experienced mild to moderate discomfort during the procedure. And 90% reported no more than a level 2 discomfort post procedure.

Effect of phenolic extracts from different extra-virgin olive oil varieties on osteoblast-like cells.

The reported incidence of osteoporosis is lower in countries in which the Mediterranean diet predominates, and this apparent relationship may be mediated by the phenolic compounds present in olive oil. The objective of this study was to determine the effect of phenolic extracts from different varieties of extra-virgin olive oil (Picual, Arbequina, Picudo, and Hojiblanca) on the differentiation, antigenic expression, and phagocytic capacity of osteoblast-like MG-63 cells. At 24 h of treatment a significant increase in phosphatase alkaline activity and significant reductions in CD54, CD80, and HLA-DR expression and in phagocytic activity were observed in comparison to untreated controls. The in vitro study performed has demonstrated that phenolic compounds from different extra virgin olive oil varieties can modulate different parameters related to osteoblast differentiation and function.

The effect of olive oil on osteoporosis prevention.

UNLABELLED: The incidence of osteoporosis and associated fractures is found to be lower in countries where the Mediterranean diet is predominant. These observations might be mediated by the active constituents of olive oil and especially phenolic compounds. OBJECTIVE: To review current knowledge by searching for all relevant publications since 2001 in the MEDLINE, EMBASE and Cochrane Library databases, using the descriptors: Mediterranean diet, virgin olive oil, phenols, bone, osteoblast and osteoporosis. RESULTS AND CONCLUSIONS: Published evidence suggests that olive oil phenols can be beneficial by preventing the loss of bone mass. It has been demonstrated that they can modulate the proliferative capacity and cell maturation of osteoblasts by increasing alkaline phosphatase activity and depositing calcium ions in the extracellular matrix. Further research on this issue is warranted, given the prevalence of osteoporosis and the few data available on the action of olive oil on bone.

Estimation of the intake of phenol compounds from virgin olive oil of a population from southern Spain.

The objective of the study was to determine the mean polyphenol composition of different varieties of virgin olive oil (VOO) habitually consumed in the region of southern Spain and to estimate the dietary exposure to olive oil polyphenols in that population. There were statistically significant differences in total polyphenols among varieties, with the Picual variety containing the largest amount with a mean value of 591.8 mg kg(-1). The main phenolic compounds found in the VOOs under study were tyrosol and hydroxytyrosol. The highest amounts of both substances were found in Picual olive oils with concentrations of 2.3-6.6 mg kg(-1). The total intake of polyphenols from VOO ranged between 8.2 mg day(-1) (SD = 4.14) for the under 19 year olds and 21.3 mg day(-1) (SD = 3) for the over 50 year olds. Some polyphenols, including tyrosol and hydroxytyrosol, were consumed principally as olive oil. The intake of these compounds in the studied population was in the range of 88.5-237.4 µg day(-1). This has particular importance as recent studies have demonstrated that hydroxytyrosol helps to improve plasma lipids levels and repair oxidative damage related to cardiovascular disease. There was a greater dietary consumption of polyphenols in olive oil among the participants who more closely followed the Mediterranean diet pattern. A higher consumption of olive oil and therefore a greater exposure to polyphenols was observed in females versus males and in participants of normal weight versus those who were overweight. The total intake of polyphenols from VOO significantly increased with higher age, reflecting the greater intake of this oil by older people, who also show a closer adherence to the Mediterranean diet. The over 50-year-old age group showed the greatest consumption of this olive oil and therefore of phenolic compounds, which are healthy protectors in the human diet that contribute to the acknowledged benefits of the Mediterranean diet.

Manejo de la psoriasis con luz ultravioleta A más psoraleno (PUVA) y luz ultravioleta B (UVB) / Use of ultraviolet light A plus psoralens (PUVA) and ultraviolet light B (UVB) in the treatment of psoriasis

Los grandes avances en el conocimiento de la inmunopatogénesis de la psoriasis en los últimos 10 años han llevado a la introducción de la terapia biológica. Sin embargo, la fototerapia sigue siendo un excelente recurso terapéutico para la enfermedad moderada a grave, no sólo por los bajos costos y relativa seguridad, sino por su gran efectividad, y siempre debe ser tenida en cuenta antes de someter al paciente a tratamientos con agentes biológicos. Infortunadamente, cada vez se realizan menos trabajos de investigación en fototerapia y, por lo tanto, se publican pocos artículos en la literatura médica sobre este tema. Siendo el Centro Dermatológico CES, Sabaneta, un centro de referencia en fototerapia desde 1995, quisimos combinar la revisión de la literatura con la experiencia acumulada durante estos años para publicar una actualización y recomendaciones para el uso de la fototerapia en psoriasis.

Proposal of a Mediterranean diet index for pregnant women.

Numerous studies have addressed the nutritional needs of pregnant women. The nutritional status of the woman before and during gestation affects the growth of the fetus and the course of the pregnancy and influences the risk of obesity for mother and infant. The aim of this study was to propose a diet quality index for pregnancy based on a Mediterranean-type diet (MDS-P), evaluating the diet of a group of pregnant women by applying the Mediterranean Diet Score (MDS) and evaluating their intake of micronutrients required in optimal amounts during pregnancy, such as Fe, folic acid and Ca. The data used to construct this index (MDS-P) were gathered by means of a FFQ specifically designed for pregnant women. The mean MDS of this group, was 4.31 (sd 1.32), considered to represent satisfactory compliance with the Mediterranean diet (range 0-8). The mean MDS-P (range 0-11), which also takes account of dietary intake or supplements of folic acid, Fe and Ca was 7.53 (sd 1.44), indicating a compliance of around 70 %. The present study findings suggest that the MDS-P, which evaluates the adequacy of folic acid, Fe and Ca as well as compliance with the Mediterranean diet, may represent a valid tool for the specific assessment of the diet of pregnant women living in countries in the Mediterranean area. Further studies are required to complete the validation process.
