Breastfeeding education: where are we going? A systematic review article

Background: UNICEF (United Nations International Children’s Emergency Fund) and WHO estimate that if all babies were breastfed for at least the first six months of their lives, the rate of morbidity and malnutrition would sig-nificantly decrease all over the world. In this view, these two organizations promoted a worldwide campaign for breastfeeding, creating the Baby Friendly Hospital Initiative (BFHI) that encourages good practices for the promotion of breastfeeding in hospitals. The aim of our study was to review the available evidence regarding the positive effects of breastfeeding, in order to suggest to most appropriate strategy to support it. Methods: The main databases including Scopus, PubMed, MEDLINE, Google scholar and Science Direct were researched to obtain the original papers related to breastfeeding education. The main terms used to literature search were "Breastfeeding education", Breastfeeding support", and “Breastfeeding healthcare policy”. The timeframe in-cluded the obtained articles was from 1980 to 2015. Results: Our analysis confirms that healthcare providers play a pivotal role in education and encouraging mothers to begin and continue breastfeeding. In this view, the adequate training of healthcare providers seems to be mandatory in order to support this practice. Moreover, adequate facilities are needed in order to promote and support breastfeeding. Conclusion: Considering the available evidence, breastfeeding should be supported among all the mothers. Based on the positive data emerging from the public awareness campaign in different Countries of the world, we strongly en-courage an accurate training for doctors and midwives and the implementation of adequate facilities in order to sup-port breastfeeding

Data comparison between pharmacological induction of labour and spontaneous delivery. A single centre experience

Objectives: To assess the differences in the maternal and fetal outcomes between pharmacological induced and sponta­neous labour in nulliparous women. Material and methods: Observational cohort study carried out over a period of 2 years. Inclusion criteria: nulliparous sin­gleton pregnancies, with cephalic fetal presentation, elective labour induction with intra-vaginal prostaglandin E2 (PGE2) gel (Prepidil® 2 mg) at a gestational age of 41 weeks. Control group: patients who entered labour spontaneously at a gestational age of ≥ 40 weeks. The main demographic maternal characteristics and intra- and postpartum data were extracted from computer records and obstetrics diaries and were used for the analysis. Results: One hundred and three patients with induction of labour and 97 with spontaneous labour were enrolled. Cesarean delivery was performed in 18 cases (17.5%), all in the induction group. There were no differences in newborn weights between the 2 groups while both the 1-minute and 5-minute Apgar scores were significantly higher in the spontaneous group (p = 0.014 and p = 0.0003, respectively). Women in the induction group had a significantly longer duration of I stage labour in comparison with spontaneous group (p < 0.0001). Conclusions: Primiparous women whose labour was induced spent a longer time in labour than women who presented in spontaneous labour. Clinicians should keep in mind that a slow rate of dilation in a woman being induced may be normal. For this reason, an arrest diagnosis needs to be carefully considered

Investigating the impact of pedoclimatic conditions on the oenological performance of two red cultivars grown throughout southern Italy

The cultivated grapevine, Vitis vinifera subsp. vinifera, possesses a rich biodiversity with numerous varieties. Each variety adapts differently to varying pedoclimatic conditions, which greatly influence the terroir expression of wine regions. These conditions impact vine growth, physiology, and berry composition, ultimately shaping the unique characteristics and typicity of the wines produced. Nowadays, the potential of the different adaptation capacities of grape varieties has not yet been thoroughly investigated. We addressed this issue by studying two grape varieties, Aglianico and Cabernet Sauvignon, in two different pedoclimatic conditions of Southern Italy. We evaluated and compared the effect of different pedoclimatic conditions on plant physiology, the microbial quality of grapes using Next-Generation Sequencing (NGS) technology, the expression trends of key genes in ripe berries and the concentration of phenolic compounds in grapes and wines by HPLC-MS, HPLC-DAD, NMR and spectrophotometric analyses. Metabolomic and microbiome data were integrated with quantitative gene expression analyses to examine varietal differences and plasticity of genes involved in important oenological pathways. The data collected showed that the phenotypic response of studied grapes in terms of vigor, production, and fruit quality is strongly influenced by the pedoclimatic conditions and, in particular, by soil physical properties. Furthermore, Aglianico grape variety was more influenced than the Cabernet Sauvignon by environmental conditions. In conclusion, the obtained findings not only reinforce the terroir concept and our comprehension of grape’s ability to adapt to climate variations but can also have implications for the future usage of grape genetic resources

Structural insights into the vapochromic behavior of Pt- and Pd-based compounds

Anionic complexes having vapochromic behavior are investigated: [K(H2O)][M(ppy)(CN)2], [K(H2O)][M(bzq)(CN)2], and [Li(H2O)n][Pt(bzq)(CN)2], where ppy = 2-phenylpyridinate, bzq = 7,8-benzoquinolate, and M = Pt(II) or Pd(II). These hydrated potassium/lithium salts exhibit a change in color upon being heated to 380 K, and they transform back into the original color upon absorption of water molecules from the environment. The challenging characterization of their structure in the vapochromic transition has been carried out by combining several experimental techniques, despite the availability of partially ordered and/or impure crystalline material. Room-temperature single-crystal and powder X-ray diffraction investigation revealed that [K(H2O)][Pt(ppy)(CN)2] crystallizes in the Pbca space group and is isostructural to [K(H2O)][Pd(ppy)(CN)2]. Variable-temperature powder X-ray diffraction allowed the color transition to be related to changes in the diffraction pattern and the decrease in sample crystallinity. Water loss, monitored by thermogravimetric analysis, occurs in two stages, well separated for potassium Pt compounds and strongly overlapped for potassium Pd compounds. The local structure of potassium compounds was monitored by in situ pair distribution function (PDF) measurements, which highlighted changes in the intermolecular distances due to a rearrangement of the crystal packing upon vapochromic transition. A reaction coordinate describing the structural changes was extracted for each compound by multivariate analysis applied to PDF data. It contributed to the study of the kinetics of the structural changes related to the vapochromic transition, revealing its dependence on the transition metal ion. Instead, the ligand influences the critical temperature, higher for ppy than for bzq, and the inclination of the molecular planes with respect to the unit cell planes, higher for bzq than for ppy. The first stage of water loss triggers a unit cell contraction, determined by the increase in the b axis length and the decrease in the a (for ppy) or c (for bzq) axis lengths. Consequent interplane distance variations and in-plane roto-translations weaken the π-stacking of the room-temperature structure and modify the distances and angles of Pt(II)/Pd(II) chains. The curve describing the intermolecular Pt(II)/Pd(II) distances as a function of temperature, validated by X-ray absorption spectroscopy, was found to reproduce the coordinate reaction determined by the model-free analysis.This research has been supported by the short-term mobility program of the National Research Council (CNR) of Italy and by the Spanish Ministerio de Economía y Competitividad (Ministerio de Ciencia Innovación y Universidades)/FEDER (Project PGC2018-094749-B-I00).Peer reviewe

Hub Genes and Pathways Related to Lemon (<i>Citrus limon</i>) Leaf Response to <i>Plenodomus tracheiphilus</i> Infection and Influenced by <i>Pseudomonas mediterranea</i> Biocontrol Activity

The lemon industry in the Mediterranean basin is strongly threatened by “mal secco” disease (MSD) caused by the fungus Plenodomus tracheiphlilus. Leaf pretreatments with Pseudomonas mediterranea 3C have been proposed as innovative tools for eco-sustainable interventions aimed at controlling the disease. In this study, by exploiting the results of previously performed RNAseq analysis, WCGNA was conducted among gene expression patterns in both inoculated (Pt) and pretreated and fungus-inoculated lemon plants (Citrus limon L.) (3CPt), and two indicators of fungal infection, i.e., the amount of fungus DNA measured in planta and the disease index (DI). The aims of this work were (a) to identify gene modules significantly associated with those traits, (b) to construct co-expression networks related to mal secco disease; (c) to define the effect and action mechanisms of P. mediterranea by comparing the networks. The results led to the identification of nine hub genes in the networks, with three of them belonging to receptor-like kinases (RLK), such as HERK1, CLAVATA1 and LRR, which play crucial roles in plant–pathogen interaction. Moreover, the comparison between networks indicated that the expression of those receptors is not induced in the presence of P. mediterranea, suggesting how powerful WCGNA is in discovering crucial genes that must undergo further investigation and be eventually knocked out

Fungal Infection Induces Anthocyanin Biosynthesis and Changes in DNA Methylation Configuration of Blood Orange [<i>Citrus sinensis</i> L. (Osbeck)]

The biosynthesis of sweet orange anthocyanins is triggered by several environmental factors such as low temperature. Much less is known about the effect of biotic stress on anthocyanin production in sweet orange, although in other species anthocyanins are often indicated as “defense molecules”. In this work, citrus fruits were inoculated with Penicillium digitatum, the causal agent of green mold, and the amount of anthocyanins and the expression of genes related to their biosynthesis was monitored by RT-real time PCR after 3 and 5 days from inoculation (DPI). Moreover, the status of cytosine methylation of DFR and RUBY promoter regions was investigated by McrBC digestion followed in real-time. Our results highlight that fungal infection induces anthocyanin production by activating the expression of several genes in the biosynthetic pathway. The induction of gene expression is accompanied by maintenance of high levels of methylation at the DFR and RUBY promoters in the inoculated fruits, thus suggesting that DNA methylation is not a repressive mark of anthocyanin related gene expression in sweet orange subjected to biotic stress. Finally, by measuring the expression levels of the Citrus DNA demethylase genes, we found that none of them is up-regulated in response to fungal infection, this result being in accordance with the observed maintenance of high-level DFR and Ruby promoter regions methylation

Isoflavone metabolism by a collection of lactic acid bacteria and bifidobacteria with biotechnological interest

Almost all soy isoflavones exist as glycosides, daidzin, genistin, and glycitin. We analyzed the capacity of 92 strains of lactic acid bacteria (LAB) and bifidobacteria with biotechnological interest to process the glycosylated isoflavones daidzin, genistin, and glycitin in their more bioavailable aglycones and their metabolites as dihydrodaidzein (DHD), O-desmethylangolensin, and equol. Representative strains of the four genera studied Lactobacillus, Enterococcus, Lactococcus, and Bifidobacterium were able to produce daidzein, genistein, and glycitein, with the exception of the lactobacilli, which did not produced glycitein in soy extracts. The production of the aglycone isoflavones could be correlated with the β-glucosidase activity of the strains. The isoflavone metabolism is limited to the glycoside hydrolysis in the most of these strains. Moreover, Enterococcus faecalis INIA P333 and Lactobacillus rhamnosus INIA P540 were able to transform daidzein in DHD. LAB and bifidobacteria studied in the present work have a great potential in the metabolism of isoflavones and could be selected for the development of functional fermented soy foods. © 2016 Taylor & Francis

Transformation of plant isoflavones into bioactive isoflavones by lactic acid bacteria and bifidobacteria

Isoflavones are usually found in nature in their glycosilated or methylated forms, and should be hydrolysed to become bioavailable and physiologically active. The deglycosylation of isoflavone C-glycosides and O-glycosides and the demethylase activity were studied in a selection of lactic acid bacteria (LAB) and bifidobacteria by assessing the degree of transformation of the pure precursor compounds, daidzin, genistin, puerarin, formononetin and biochanin A into daidzein or genistein. Only one Bifidobacterium strain and two Enterococcus strains hydrolysed the C-glycosidic bond of puerarin, while deglycosylation of O-glycosides daidzin and genistin was observed in all the tested strains. Demethylation of biochanin A and formononetin was observed in the most of LAB and bifidobacteria. Besides, the subsequent metabolites dihydrodaidzein and dihydrogenistein where produced by many of the strains via daidzein and genistein. In this work, we show the potential of LAB and bifidobacteria as part of functional foods because of their ability to transform plant isoflavones into their bioactive forms. © 2017 Elsevier Lt

Application of recombinant lactic acid bacteria and bifidobacteria able to enrich soy beverage in dihydrodaidzein and dihydrogenistein

8 Pág.Dihydrodaidzein (DHD) and dihydrogenistein (DHG) are intermediate compounds in the production of equol and 5-hydroxy-equol from daidzein and genistein by certain intestinal bacteria. In this work, we explored the heterologous expression of the daidzein reductase gene from Slackia isoflavoniconvertens DSM22006, responsible for the formation of DHD and DHG, in nine lactic acid bacteria and Bifidobacterium strains under a strong constitutive promoter in the plasmid pNZ:TuR.dzr. All the transformed strains showed high production of DHD and DHG both from pure daidzein and genistein and from the isoflavone glycosides present in soy beverage. In addition, Lactococcus lactis MG1363 pNZ:TuR.dzr, expressing the recombinant daidzein reductase, incremented the production of equol by equol-producing intestinal microbiotas in a colonic environment. Nevertheless, other recombinant strains tested showed the opposite effect to L. lactis MG1363 pNZ:TuR.dzr in the production of equol by intestinal microbiota. Here, we describe for the first time the production of 5-hydroxy-equol by human intestinal microbiota, both from genistein and DHG. The use of DHD and DHG as substrates, compared to daidzein and genistein, resulted in an increment of equol and 5-hydroxy-equol production by intestinal microbiota. The recombinant strains developed would be of value for the development of fermented soy beverage enriched in DHD and DHG with the aim of facilitate equol and 5-hydroxy-equol production by intestinal microbiota.This work was supported by project RTA2017-00002-00-00 from the Spanish Ministry of Science, Innovation and University.Peer reviewe
