Pelvic floor trauma during childbirth is highly prevalent and is associated with long term risks of incontinence and pelvic organ prolapse. Societies and organizations have published clinical guidelines in order to standardise and improve the management of perineal care. The aim of this study was to systematically evaluate the quality of clinical guidelines on obstetric perineal trauma and care using the AGREE II instrument. We searched Medline, PubMed, Web of Science and ScienceDirect databases from inception until the 15th of December 2018 using the terms "guideline" OR "guidelines", OR "guidance", OR "recommendation" AND "obstetric anal sphincter injury", OR "perineal laceration" OR "perineal tear" OR "perineal trauma" OR "vaginal tear". Twelve guidelines were included, in English and Spanish.The assessment of the guidelines was performed using AGREE II by 5 appraisers.Ten guidelines scored more than 50 %, and 3 of them scored higher than 70 %. Two guidelines scored less then 50 % and were considered as low quality. Level of evidence and grade of recommendations were used by 7 guidelines of the 12 guidelines. Although some guidelines received high scores, there is space for improvement of the standards of guidelines. V.BACKGROUND The amount of chewing might be relevant in reducing hyperglycaemia in diabetic patients. The study assessed the impact of enhanced chewing on glycaemic control in women with gestational diabetes mellitus (GDM). METHODS As an open-label, mono-centre randomized controlled trial, 59 women with recent diagnosis of GDM were included. They received either routine care or additional chewing gum intervention. SMBG was performed for five days. RESULTS No significant impact on mean values of postprandial glucose levels were observed. The estimated mean differences (intervention vs. control group) were 4.9 mg/dl, 98.4 %CI -7.2-17.1 (breakfast); -4.5 mg/dl, 98.4 %CI -15.1-6.0 (lunch); -3.8 mg/dl, 98.4 %CI -15.9 to 8.4 (dinner). OGTT levels at 60 and 120 min. were associated with glucose levels after breakfast. CONCLUSION In conclusion, no significant differences in blood glucose levels were observed between the groups and therefore major effects of chewing on hyperglycaemia in women with GDM could be excluded. TRIAL REGISTRATION ClinicalTrials.gov; NCT03961542, Date of registration 20.01.2019. Retrospectively registered. V.A rapid, sensitive, and highly selective method for determining nitrite in food has been developed. This method is based on the reaction of nitrite with the amino group of 3,3,5,5-tetramethylbenzidine (TMB) to form a diazonium salt, and then the diazonium salt and glucosamine hydrochloride are coupled to each other to form an orange compound. The optimal conditions for maximum color and other analytical parameters were studied. A colorimetric method for nitrite detection has been developed with an outstanding correlation coefficient (R2 = 0.9944), a wide linear range (1-75 μM) and 0.73 μM limit of detection (at S/N = 3) for nitrite ions. This method was successfully applied to the determination of nitrite in a variety of foods and gave recoveries in the range between 100.16% and 103.07%, demonstrating that the accuracy, reliability and potential application of this assay for monitoring nitrite in foods. Levels of polycyclic aromatic hydrocarbons (PAHs) in cocoa beans of several varieties originating from different countries and their derived products from one technological line were examined. Ravoxertinib ic50 PAHs analysis was performed using HPLC-FLD/DAD and confirmed by GC-MS. Significant differences in total 19 PAHs contents between raw cocoa beans of different varieties and origins were observed. The highest sums of 19 PAHs were determined in roasted cocoa beans, cocoa mass and cocoa butter (16.69-74.15 μg kg-1 of fat). The roasting temperature of 160 °C led to PAHs formation, though not the heavy ones. Lowering temperature to 140 °C while extending the time minimized the total contamination but to a small extent. In all samples relatively low levels of total contamination were noted, with light PAHs being predominant and the sum of 4 heavy and marker PAHs much lower than the maximum legal limit. Therefore, analysed products, especially chocolate, do not threaten consumers' health. A heterocyclic hypercrosslinked polymer (Py-DMB HCP) was prepared by Friedel-Crafts alkylation reaction using pyrrole as monomer and p-dimethoxybenzene as crosslinker. The Py-DMB HCP was employed as an adsorbent for solid-phase extraction (SPE) of phenylurea herbicides (PUHs) and showed superior extraction performance. Thus, a sensitive analytical method for the determination of PUHs from soybean milk and tomato samples was established by combining Py-DMB HCP based SPE with high performance liquid chromatography. Under the optimal conditions, good sensitivity was achieved with the detection limits of 0.10-0.20 ng mL-1 and 0.06-0.15 ng g-1 for soybean milk and tomato samples, respectively. The linearity range of PUHs was 0.3-150.0 ng mL-1 and 0.2-150.0 ng g-1, respectively. The recoveries were 87.4% to 116% with relative standard deviations lower than 6.5%. Density functional theory calculation was performed to study the intermolecular interaction mechanism, demonstrating the coexistence of both the H-bonding and π-π interactions in the adsorption process. The inhibitory mechanisms of ferulic acid against α-amylase and α-glucosidase were investigated by enzyme kinetic analysis, circular dichroism (CD), Fourier-transform infrared (FT-IR) spectroscopy, fluorescence quenching and molecular docking. Results indicated that ferulic acid strongly inhibited α-amylase (IC50 0.622 mg ml-1) and α-glucosidase (IC50 0.866 mg ml-1) by mixed and non-competitive mechanisms, respectively. CD spectra and fluorescence intensity measurements confirmed that the secondary structure of α-amylase and α-glucosidase were changed and the microenvironments of certain amino acid residues were modulated by the binding of ferulic acid. FT-IR spectra indicated that the interaction between ferulic acid and α-amylase/α-glucosidase mainly involved in non-covalent bonds. Molecular docking further demonstrated that the interaction forces between ferulic acid and α-amylase/α-glucosidase were hydrogen bonds, with the binding energy of -5.30 to -5.10 and -5.70 kcal mol-1, respectively. This study might provide a theoretical basis for the designing of novel functional foods with ferulic acid.
