Computer-aided laccase engineering: toward biological oxidation of arylamines

Oxidation of arylamines, such as aniline, is of high industrial interest and laccases have been proposed as biocata-lysts to replace harsh chemical oxidants. However, the reaction is hampered by the redox potential of the substrate at acid pH and enzyme engineering is required to improve the oxidation. In this work, instead of trying to improve the redox potential of the en-zyme, we aim towards the (transient) substrate’s one and propose this as a more reliable strategy. We have successfully combined a computational approach with experimental validation to rationally design an improved biocatalyst. The in silico protocol combines classical and quantum mechanics to deliver atomic and electronic level detail on the two main processes involved: substrate binding and electron transfer. After mutant expression and comparison to the parent type, kinetic results show that the protocol accurately predicts aniline’s improved oxidation (2-fold kcat increase) in the engineered variant for biocatalyzed polyaniline production.This study was supported by the INDOX (KBBE-2013-7-613549) EU-project, and the NOESIS (BI0201456388-R) and OxiDesign (CTQ2013-48287-R) Spanish project.

Harms in Systematic Reviews Paper 2: Methods used to assess harms are neglected in systematic reviews of gabapentin

Objective: We compared methods used with current recommendations for synthesizing harms in systematic reviews and meta-analyses (SRMAs) of gabapentin. Study Design & Setting: We followed recommended systematic review practices. We selected reliable SRMAs of gabapentin (i.e., met a pre-defined list of methodological criteria) that assessed at least one harm. We extracted and compared methods in four areas: pre-specification, searching, analysis, and reporting. Whereas our focus in this paper is on the methods used, Part 2 examines the results for harms across reviews. Results: We screened 4320 records and identified 157 SRMAs of gabapentin, 70 of which were reliable. Most reliable reviews (51/70; 73%) reported following a general guideline for SRMA conduct or reporting, but none reported following recommendations specifically for synthesizing harms. Across all domains assessed, review methods were designed to address questions of benefit and rarely included the additional methods that are recommended for evaluating harms. Conclusion: Approaches to assessing harms in SRMAs we examined are tokenistic and unlikely to produce valid summaries of harms to guide decisions. A paradigm shift is needed. At a minimal, reviewers should describe any limitations to their assessment of harms and provide clearer descriptions of methods for synthesizing harms

Harms in Systematic Reviews Paper 3: Given the same data sources, systematic reviews of gabapentin have different results for harms

Objective: In this methodologic study (Part 2 of 2), we examined the overlap in sources of evidence and the corresponding results for harms in systematic reviews for gabapentin. Study Design & Setting: We extracted all citations referenced as sources of evidence for harms of gabapentin from 70 systematic reviews, as well as the harms assessed and numerical results. We assessed consistency of harms between pairs of reviews with a high degree of overlap in sources of evidence (>50%) as determined by corrected covered area (CCA). Results: We found 514 reports cited across 70 included reviews. Most reports (244/514, 48%) were not cited in more than one review. Among 18 pairs of reviews, we found reviews had differences in which harms were assessed and their choice to meta-analyze estimates or present descriptive summaries. When a specific harm was meta-analyzed in a pair of reviews, we found similar effect estimates. Conclusion: Differences in harms results across reviews can occur because the choice of harms is driven by reviewer preferences, rather than standardized approaches to selecting harms for assessment. A paradigm shift is needed in the current approach to synthesizing harms

The Southern European Atlantic Diet is associated with lower concentrations of markers of coronary risk

Objective: The Southern European Atlantic Diet (SEAD) is the traditional diet of Northern Portugal and Galicia, a region in northwest Spain. The SEAD has been associated with a lower risk of non-fatal acute myocardial infarction, but the mechanisms of this association have not yet been investigated. Thus, we examined the association between the SEAD and numerous biomarkers of coronary risk, blood pressure and anthropometrics. Methods: Cross-sectional study conducted in 2008–2010 among 10,231 individuals representative of the population aged 18 years and older in Spain. Diet was assessed with a validated computerized diet history. SEAD adherence was measured with an index including 9 food components (fresh fish, cod, red meat and pork products, dairy products, legumes and vegetables, vegetable soup, potatoes, whole-grain bread, and wine), which ranges from 0 (lowest adherence) to 9 (highest adherence). C-reactive protein, uric acid, total cholesterol, LDL-cholesterol, HDL-cholesterol, triglycerides, glucose, glycated hemoglobin, insulin, leptin, fibrinogen, were determined in 12-h fasting blood samples, while creatinine and urine albumin were determined in urine. Results: Mean SEAD score was 2.9 points (inter-quartile range 2–4 points). Higher SEAD adherence was associated with a lower level of plasma C-reactive protein (adjusted difference in geometric means between the highest and lowest SEAD quartiles −0.2 mg/l; p for trend <0.001), plasma triglycerides (−3.4 mg/dl; p for trend 0.012), insulin (−0.5 mU/l; p for trend <0.001), HOMA-IR (−0.12; p for trend <0.001), urine albumin (−0.8 mg/l; p for trend <0.001), urine albumin-creatinine ratio (−0.3 mg/g creatinine; p for trend <0.034), and systolic blood pressure (−1.6 mm Hg; p for trend <0.001). Conclusions: This study identifies possible mediators of the effect of SEAD on myocardial infarction, because SEAD is associated with a lower concentration of markers of inflammation and with reduced triglycerides, insulin, insulin resistance, and systolic blood pressure

Association of cooking patterns with inflammatory and cardio-metabolic risk biomarkers

Diet has been clearly associated with cardiovascular disease, but few studies focus on the influence of cooking and food preservation methods on health. The aim of this study was to describe cooking and food preservation patterns, as well as to examine their association with inflammatory and cardio-metabolic biomarkers in the Spanish adult population. A cross-sectional study of 10, 010 individuals, representative of the Spanish population, aged 18 years or over was performed using data from the ENRICA study. Food consumption data were collected through a face-to-face dietary history. Cooking and food preservation patterns were identified by factor analysis with varimax rotation. Linear regression models adjusted for main confounders were built. Four cooking and food preservation patterns were identified. The Spanish traditional pattern (positively correlated with boiling and sautéing, brining, and light frying) tends to be cardio-metabolically beneficial (with a reduction in C-reactive protein (-7.69%)), except for high density lipoprotein cholesterol (HDL-c), insulin levels, and anthropometrics. The health-conscious pattern (negatively correlated with battering, frying, and stewing) tends to improve renal function (with a reduction in urine albumin (-9.60%) and the urine albumin/creatinine ratio (-4.82%)). The youth-style pattern (positively correlated with soft drinks and distilled alcoholic drinks and negatively with raw food consumption) tends to be associated with good cardio-metabolic health except, for lower HDL-c (-6.12%), higher insulin (+6.35%), and higher urine albumin (+27.8%) levels. The social business pattern (positively correlated with the consumption of fermented alcoholic drinks, food cured with salt or smoke, and cured cheese) tends to be detrimental for the lipid profile (except HDL-c), renal function (urine albumin +8.04%), diastolic blood pressure (+2.48%), and anthropometrics. Cooking and food preservation patterns showed a relationship with inflammatory and cardio-metabolic health biomarkers. The Spanish traditional pattern and the health-conscious pattern were associated with beneficial effects on health and should be promoted. The youth-style pattern calls attention to some concerns, and the social business pattern was the most detrimental one. These findings support the influence of cooking and preservation patterns on health
