Dental care as a risk factor for transfusion transmissible infections in blood donors: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVES The deferral policy for blood donation after dental care is based on the precautionary principle. The aim of this systematic review is to give an overview of the scientific evidence concerning the risk of transfusion transmissible infections (TTIs) after dental care. MATERIALS AND METHODS Four databases were searched: Medline, the Cochrane Library, Embase and Web of Science. Screening was independently performed by two reviewers. The quality of evidence was evaluated using the Grades of Recommendation, Assessment, Development and Evaluation principle. A meta-analysis was performed to assess the association between dental treatment and TTI markers. RESULTS A total of 22 studies were included. Meta-analysis of 16 studies showed an increased association of TTIs with dental treatment, however with large heterogeneity. Subgroup analysis revealed a significant increased association of hepatitis B virus (HBV) with dental treatment [odds ratio 1.79, 95% confidence interval (1.48; 2.18)]. There was conflicting evidence concerning the risk of hepatitis C virus (HCV). One study could not demonstrate a statistically significant increased association of human T-lymphotropic virus type I with dental treatment. Three studies showed a significant increased association of HCV with tooth extraction [odds ratio 1.48, 95% confidence interval (1.11; 1.97)]. Finally, there is conflicting evidence concerning the risk of HBV or HCV after dental cleaning. One study could not demonstrate an association between HIV and dental cleaning. All evidence is of very low certainty and results cannot be considered precise. CONCLUSION Studies of high quality concerning the risk of TTI after dental care in blood donors are scarce. An association of HBV after dental treatment and HCV after tooth extraction was demonstrated but evidence is of very low certainty. The currently identified studies are of too low certainty to make any suggestions regarding the value of deferral or deferral times.
Dietary inflammatory index and incidence of and death from primary liver cancer: A prospective study of 103,902 American adults

Chronic inflammation plays an important role in primary liver cancer (PLC) etiology and can be influenced by dietary habits. No prospective study has investigated the association of dietary inflammatory index (DII) with PLC incidence and mortality. Therefore, we used prospective data from the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial to fill this gap. The DII was calculated from a validated 137‐item food frequency questionnaire in a cohort of 103,902 individuals. Cox regression was used to estimate hazard ratios (HRs) for PLC incidence, and competing risk regression was used to estimate subdistribution HRs (SHRs) for PLC mortality. Restricted cubic spline regression was employed to identify the potential dose–response pattern. A total of 120 PLC cases and 102 PLC deaths were observed during follow‐up. Higher DII scores from food and supplement were found to be associated with higher risks of developing PLC (HRTertile 3 vs. 1 2.05; 95% confidence interval [CI] 1.23–3.41) and death from this disease (SHRTertile 3 vs. 1 1.97; 95% CI 1.13–3.41). Similar results were obtained for DII score from food only. A nonlinear dose–response pattern was identified for the aforementioned associations (all pnonlinearity < 0.05). Overall, a more pro‐inflammatory diet, as suggested by higher DII scores, is associated with higher risks of PLC incidence and mortality. These findings indicate that encouraging intake of more anti‐inflammatory dietary components and reducing intake of pro‐inflammatory components represent an attractive strategy to reduce PLC incidence and mortality.
N-Terminal Acetylation Stabilizes SIGMA FACTOR BINDING PROTEIN1 Involved in Salicylic Acid-Primed Cell Death1[CC-BY]

N-terminal acetylation regulates SIB1 protein stability to ensure its function in salicylic acid-primed cell death. N-terminal (Nt) acetylation (NTA) is an ample and irreversible cotranslational protein modification catalyzed by ribosome-associated Nt-acetyltransferases. NTA on specific proteins can act as a degradation signal (called an Ac/N-degron) for proteolysis in yeast and mammals. However, in plants, the biological relevance of NTA remains largely unexplored. In this study, we reveal that Arabidopsis (Arabidopsis thaliana) SIGMA FACTOR-BINDING PROTEIN1 (SIB1), a transcription coregulator and a positive regulator of salicylic acid-primed cell death, undergoes an absolute NTA on the initiator Met; Nt-acetyltransferase B (NatB) partly contributes to this modification. While NTA results in destabilization of certain target proteins, our genetic and biochemical analyses revealed that plant NatB-involved NTA instead renders SIB1 more stable. Given that the ubiquitin/proteasome system stimulates SIB1 degradation, it seems that the NTA-conferred stability ensures the timely expression of SIB1-dependent genes, mostly related to immune responses. Taking our findings together, here we report a noncanonical NTA-driven protein stabilization in land plants.
Shape Deformation in Ion Beam Irradiated Colloidal Monolayers: An AFM Investigation

Self-assembly of colloidal monolayers represents a prominent approach to the fabrication of nanostructures. The modification of the shape of colloidal particles is essential in order to enrich the variety of attainable patterns which would be limited by the typical assembly of spherical particles in a hexagonal arrangement. Polymer particles are particularly promising in this sense. In this article, we investigate the deformation of closely-packed polystyrene particles under MeV oxygen ion irradiation at normal incidence using atomic force microscopy (AFM). By developing a procedure based on the fitting of particle topography with quadrics, we reveal a scenario of deformation more complex than the one observed in previous studies for silica particles, where several phenomena, including ion hammering, sputtering, chemical modifications, can intervene in determining the final shape due to the specific irradiation conditions. In particular, deformation into an ellipsoidal shape is accompanied by shrinkage and polymer redistribution with the presence of necks between particles for increasing ion fluence. In addition to casting light on particle irradiation in a regime not yet explored, we present an effective method for the characterization of the colloidal particle morphology which can be applied to describe and understand particle deformation in other regimes of irradiation or with different techniques.
Composition Engineered Metal-Organic-Framework-Based Microneedles for Glucose-Mediated Transdermal Insulin Delivery.

Elaborately designed glucose-responsive insulin delivery systems are highly desirable for the treatment of diabetes because it can secrete insulin depending on blood glucose levels. Herein, a mimic multi-enzyme metal-organic framework (MOF)-based (insulin and glucose oxidase-loaded cobalt-doped ZIF-8, abbreviated as Ins/GOx@Co-ZIF-8) stimuli-responsive microneedles (MNs) was designed for painless glucose-mediated transdermal administration. In this work, GOx and Co2+ ions were engineered into MOF to construct a mimic multi-enzyme vehicle. GOx in the MOF, as the glucose-responsive factor, could catalyze glucose into gluconic acid with the formation of H2O2 as the by-product. The gluconic acid formed decreases the local pH in MOF, resulting the degradation of MOF and thus, preloaded insulin would be released. Meanwhile, catalyzed by Co2+ ions in the MOF, the by-product H2O2 was decomposed. Possible free Co2+ ions would be chelated by EDTA-SiO2 nanoparticles in MNs and removed by peeling MNs off. The as-obtained mimic multi-enzyme MOF-based MNs showed good dependence on glucose concentration without divulging H2O2 and Co2+ ions and enough stiffness to penetrate into skin. This study offers a new strategy, using facilely synthesized MOF as depots to integrate with MNs, for designing stimuli-responsive transdermal drug delivery systems.
Production of bioethanol from biomass of microalgae Dunaliella tertiolecta

Biofuel production from microalgae biomass appears as a promising long term alternative. Dunaliella tertiolecta is a microalgae with high tolerance to salinity, temperature, and light, making it relatively easy to grow. The aim of this study was to establish a pilot-scale culture to evaluate the biomass yield and bioethanol production. The cell culture of D. tertiolecta was started in 20 ml tubes and escalated to 20 L containers. The biomass yield was 0.153 g L -1 of dry basis (db) and its characterization showed protein (37% db) as major component followed by carbohydrates (35.6), lipids (13% db) and ash (6.5%). The carbohydrate fraction was composed of starch (27.1% db) and fiber (8.5 %) and its neutral sugar characterization yield glucose (91% molar). The main components of the lipid fraction were linolenic and palmitic acids. The biomass was subjected to an acid pre-treatment for the saccharification of complex carbohydrates, and the hydrolyzed biomass was fermented by Saccharomyces cerevisiae. It was possible to produce 0.615 ml g -1 of ethanol. In conclusion, D. tertiolecta has the potential for bioethanol production, making it a promising option for the biofuels future. Keywords— biofuels, microalgae, bioethanol, fermentation, composition.
The mid-childhood and adolescent antecedents of women’s external locus of control orientation

Background: External locus of control orientation (ELOC) is a powerful predictor of adverse consequences in regard to health, educational attainment, inter-personal relationships and well-being. Although many cross-sectional studies have been carried out, relatively little is known about antecedent factors influencing the development of ELOC. Methods: Over 12,000 pregnant women who enrolled in the Avon Longitudinal Study of Parents and Children (ALSPAC) in south-west England, had completed a brief version of the Adult Nowicki-Strickland Internal-External LOC scale, together with detailed questions concerning their own parents and childhood. A series of hypothesis-free structured backwards stepwise logistic regression analyses used an exposome approach with ELOC as the outcome. Results: Significant positive associations were found with smoking of the parents of the surveyed women, including prenatal exposure, and their own onset of regular smoking in mid-childhood (6-11 years). Increased odds of ELOC were also found with the absence of their fathers in early childhood, presence of older siblings, and with being born and brought up in the same area as they resided in at the time surveyed. Protective influences in the surveyed women included positive rating of their mother’s care, having a relatively educated mother, attending boarding school, their own age (the older they were, the less likely were they to have an external orientation), having a mentally ill parent, a sibling hospitalized or a relative die. Conclusions: There are two conclusions: (i) that not all stressful events contribute to the development of ELOC and it would be essential for models of antecedents of ELOC to take note of this complexity, and (ii) there are consistent (albeit unexpected) findings that highlight associations with cigarette smoke exposure of the woman from fetal life through to when starting to smoke regularly herself in mid-childhood. It is important that these findings are tested in other populations.
Treatment Patterns for Chronic Comorbid Conditions in Patients With Cancer Using a Large-Scale Observational Data Network

PURPOSE Patients with cancer are predisposed to developing chronic, comorbid conditions that affect prognosis, quality of life, and mortality. While treatment guidelines and care variations for these comorbidities have been described for the general noncancer population, less is known about real-world treatment patterns in patients with cancer. We sought to characterize the prevalence and distribution of initial treatment patterns across a large-scale data network for depression, hypertension, and type II diabetes mellitus (T2DM) among patients with cancer. METHODS We used the Observational Health Data Sciences and Informatics network, an international collaborative implementing the Observational Medical Outcomes Partnership Common Data Model to standardize more than 2 billion patient records. For this study, we used 8 databases across 3 countries—the United States, France, and Germany—with 295,529,655 patient records. We identified patients with cancer using SNOMED (Systematized Nomenclature of Medicine) codes validated via manual review. We then characterized the treatment patterns of these patients initiating treatment of depression, hypertension, or T2DM with persistent treatment and at least 365 days of observation. RESULTS Across databases, wide variations exist in treatment patterns for depression (n = 1,145,510), hypertension (n = 3,178,944), and T2DM (n = 886,766). When limited to 6-node (6-drug) sequences, we identified 61,052 unique sequences for depression, 346,067 sequences for hypertension, and 40,629 sequences for T2DM. These variations persisted across sites, databases, countries, and conditions, with the exception of metformin (73.8%) being the most common initial T2DM treatment. The most common initial medications were sertraline (17.5%) and escitalopram (17.5%) for depression and hydrochlorothiazide (20.5%) and lisinopril (19.6%) for hypertension. CONCLUSION We identified wide variations in the treatment of common comorbidities in patients with cancer, similar to the general population, and demonstrate the feasibility of conducting research on patients with cancer across a large-scale observational data network using a common data model.
Explaining Intricate Morphometric Variability with Environmental Predictors: The Case of Globularia cordifolia Species Complex

Globularia is a genus of small evergreen and perennial shrubs that are widespread in Europe. Globularia section Empetron includes a group of three species, G. cordifolia, G. meridionalis, and G. neapolitana, that have been taxonomically disputed for more than 150 years. Many morphological features have been proposed to discriminate these species. Nevertheless, evidence from both past and recent literature suggest that these differences among species are not consistent. In order to shed new light in this long-disputed group, we investigated 10 populations of the G. cordifolia species complex with both classical and geometric morphometrics and used environmental predictors in multivariate regression to explain patterns of variation. Our results showed that bract area and calyx teeth length are correlated with solar radiation and annual precipitation, whereas leaf dry mass per unit area can be explained by temperature seasonality. Leaf shape can be explained by temperature seasonality as well, although with a lower amount of explanatory and predictive power. Despite a comparatively low sample size in terms of populations, our results were based on a large number of individuals and were supported by a robust statistical approach. We can conclude that differences among the three species of Globularia could be related to the combined effects of several ecological variables and might not have taxonomical value. Our novel approach provided an ecological interpretation on a species complex that makes up a continuum of forms within the environmental framework of the Mediterranean basin.
Refractive outcomes comparing SMILE and FS-LASIK for High Myopia.

PURPOSE To compare the long-term refractive effects of small incision lenticule extraction (SMILE) and femtosecond laser-assisted laser in situ keratomileusis (FS-LASIK) for correction of high myopia and astigmatism. SETTING The Eye and ENT Hospital of Fudan University DESIGN:: Retrospective case series. METHODS This study included 121 patients (121 eyes: 75 in SMILE group and 46 in FS-LASIK group) who underwent SMILE or FS-LASIK for high myopia. Subgroup analyses of high myopia (<-9.00 diopters [D]) and extremely high myopia (≥ -9.00 D). The main outcome measure was refractive predictability compared between SMILE and FS-LASIK. Secondary outcomes includeded efficacy, safety, and residual astigmatism. RESULTS We found no differences in terms of refractive predictability between SMILE and FS-LASIK in eyes with high myopia: 56% versus 58.7% achieved ± 0.5 D of attempted correction (P=0.771), and 81.3% versus 76.1% achieved ± 1.0 D of attempted correction (P=0.489), respectively. Efficacy indices of the SMILE and FS-LASIK groups were 1.02 ± 0.24 and 1.03 ± 0.24 (P=0.742); safety indices were 1.23 ± 0.22 and 1.20 ± 0.24 (P=0.324), respectively. LogMAR UDVA and spherical equivalent in the high myopia subgroup were better than those in the extremely high myopia subgroup after both SMILE and FS-LASIK (P < 0.01). CONCLUSIONS SMILE and FS-LASIK were both effective in correcting high myopia and myopic astigmatism. However, both techniques may require further nomogram adjustments when treating eyes with extremely high myopia.
Anger attacks are associated with persistently elevated irritability in MDD: findings from the EMBARC study

Abstract Background This report tests the association of self-reported symptoms of irritability with overt behavior of anger attacks (uncharacteristic sudden bouts of anger that are disproportionate to situation and associated with autonomic activation). Methods Participants of the Establishing Moderators and Biosignatures of Antidepressant Response in Clinical Care study who completed Massachusetts General Hospital Anger Attacks questionnaire were included (n = 293). At each visit, the 17-item Hamilton Depression Rating Scale and the 16-item Concise Associated Symptom Tracking scale were used to measure depression, anxiety, and irritability. In those with anger attacks present v. those without anger attacks, separate t tests and mixed model analyses compared afore-mentioned symptoms at baseline and changes with treatment respectively. As anger attacks may occur without aggressive behaviors, analyses were repeated based only on the presence of aggressive behaviors. Results At baseline, those with anger attacks (n = 109) v. those without anger attacks (n = 184) had similar levels of depression but higher levels of irritability [effect size (d) = 0.80] and anxiety (d = 0.32). With acute-phase treatment, participants with anger attacks experienced a greater reduction in irritability (p < 0.001) but not in depression (p = 0.813) or anxiety (p = 0.771) as compared to those without anger attacks. Yet, irritability levels at week-8 were higher in those with anger attacks (d = 0.32) than those without anger attacks. Similar results were found in participants with aggressive behaviors. Conclusions The presence of anger attacks in outpatients with major depressive disorder may identify a sub-group of patients with persistently elevated irritability.
Nbr1-regulated autophagy in Lactoferrin-induced osteoblastic differentiation

ABSTRACT The molecular mechanism of autophagy in Lactoferrin (LF) induced osteoblast differentiation is not fully demonstrated. In this study, alkaline phosphatase (ALP) activity, alizarin red S staining and ELISA were used to study N-terminal propeptide of type I procollagen (PINP) expression. mRFP-GFP-LC3 adenoviruses, mono-dansylcadaverine (MDC) staining, scanning electron microscopy, and western blot analysis was employed to probe the LF induced autophagy. The interaction between autophagy receptor Neighbor of Brca1 gene (Nbr1) and pp38 was studied. 3-methyladenine (3-MA) and chloroquine (CQ) could inhibit the activity of ALP, PINP and the autophagy in LF group. LF treatment could up-regulate and down-regulate the expressions of pp38 and Nbr1with a dose-dependent manner, respectively. LF could inhibit the recognition of pp38 and Nbr1. In addition, LF can prompt Nbr1-medicated autophagy and prevent pp38 degradation by autophagy. LF can induce Nbr1-mediated autophagy and inhibit pp38 entering into autophagy flux in the physiological process of osteoblast differentiation.

Modulation of the intestinal microbiota and the metabolites produced by the administration of ice cream and a dietary supplement containing the same probiotics

Abstract The aim of the present work was to compare the capacity to modulate the intestinal microbiota and the production of metabolites after 14 d administration of a commercial dietary supplement and a manufactured ice cream, both containing the same quantity of inulin and the same viable counts of Lactobacillus acidophilus LA-5 and Bifidobacterium animalis BB-12, using the Simulator of the Human Intestinal Microbial Ecosystem (SHIME®) model. Samples of the colonic contents were evaluated microbiologically by real-time quantitative PCR (qRT-PCR) and next-generation sequencing and chemically by the production of SCFA (acetate, propionate and butyrate) and ammonium ions ($\text{NH}_4^ + $). Statistical analyses were carried out for all the variables using the two-way ANOVA followed by the Tukey multiple comparisons test (P < 0·05) for metabolite production, qRT-PCR and the bioinformatics analysis for microbiota diversity. Dietary supplement and ice cream were able to deliver the probiotic L. acidophilus and B. animalis to the simulated colon and modulate the microbiota, increasing beneficial micro-organisms such as Bifidobacterium spp. , Bacteroides spp. and Faecalibacterium spp. for dietary supplement administration, and Lactobacillus spp. for ice cream supplementation. However, the ice cream matrix was probably more favourable for the maintenance of the metabolic activity of the probiotics in the SHIME® model, due to the larger amounts of acetate, propionate, butyrate and ammonium ions obtained after 14 d of supplementation. In conclusion, both ways of probiotic supplementation could be efficient, each with its own particularities.
Diamond Sampling Structure based BRINT Descriptor for Texture Classification

The problem of texture classification is discussed in this paper. Local Binary Patterns (LBP) and most of LBP variants still suffer from high noise sensitivity, high dimensionality and computational complexity. An approach in which points are sampled in a diamond like structure is proposed and fixing the number of neighbor samples to 8. This decreases the feature dimension significantly. The points are sampled in different neighborhoods and encoded over a number of scales. The sampling points are averaged along radial direction for robustness of noise. In addition, a new descriptor based on Binary Rotation Invariant and Noise Tolerant (BRINT) descriptor is created to extract features. Unlike BRINT, uniform rotation invariant patterns in place of rotation invariant patterns is used for each of the three descriptors. These three descriptors are added jointly to get proposed descriptor. The experimental results on two benchmark texture datasets (OUTEX_TC_12_000 and KTH-TIPS2b) prove that the proposed approach performs better than other state-of-the-art LBP variants both under noise free and noisy conditions. The proposed approach is tested under different noise environments of Gaussian, salt and pepper and speckle to demonstrate its robustness of noise.
