Drawbacks associated with the use of chemical fungicides to control plant pathogenic fungi such as Botrytis cinerea stimulate the need for alternatives. Therefore, the present study was carried out to determine the antifungal potentials of Moringa oleifera extracts against B. cinerea. Phytochemical analysis using qualitative chemical tests revealed the presence of huge amount of crucial phytochemicals compounds like phenolic compounds, alkaloids and saponins in the M. oleifera leaf extract. Antifungal bioassay of the crude extracts indicated better mycelial growth inhibition by methanol leaf extract (99%). The minimum inhibitory concentration (MIC) was 5 mg/ml with 100% spore germination inhibition and minimum fungicidal concentration (MFC) was 10 mg/ml with 98.10% mycelial growth inhibition using broth micro dilution and poisoned food techniques. Gas chromatography-mass spectrometry (GC-MS) analysis led to the identification of 67 volatile chemical compounds in the leaf extract with 6-decenoic acid (Z)- (19.87%) was the predominant compound. Further chemical elucidation of the crude extracts performed by liquid chromatography with tandem mass spectrometry (LC-MS/MS) showed the presence of non-volatile chemical compounds, mostly flavones, flavonoids and phenolic acids (i.e. quercetin and kaempferol). Scanning electron microscopy and transmission electron microscopy analysis showed positive effect of M. oleifera leaf extract on the treated conidia and mycelium of B. cinerea. Findings revealed that irreversible surface and ultra-structural changes with severe detrimental effects on conidia and mycelium morphology compared to control treatment. Overall findings suggested that M. oleifera leaf extract is a promising candidate for biological control of fungal pathogens, thus limiting overdependence on chemical fungicides.
To identify the factors associated with food neophobia in children through a systematic review.
This research was based on the recommendations of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. The research was carried out in the PubMed, Science Direct, and Scientific Electronic Library Online databases, with the combination of health descriptors in English and Portuguese ("Food Neophobia" OR "Feeding Behavior" OR "Food Preferences" OR "Food Selectivity") AND Child, from 2000 to 2019. Studies that evaluated factors associated with food neophobia in children were included. The quality of the studies was assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies (QATQS).
19 studies were included in the systematic review. The prevalence of food neophobia ranged from 12.8 to 100%. The studies used three different scales to measure the level of food neophobia. The main factors associated with food neophobia were parental influence on children's eating habits, children's innate preference for sweet and savory flavors, influence of the sensory aspect of the food, parents' pressure for the child to eat, parents' lack of encouragement and/or affection at mealtime, childhood anxiety, and diets with low variety and low nutritional quality.
The factors associated with food neophobia permeate several areas of the child's life, thus, interprofessional follow-up becomes essential in the intervention process.

Asthma and obesity are prevalent and interrelated diseases. In the pediatric population, the effect of systemic inflammation associated to obesity, leading to inflammation of the airways, is currently controversial. Our aim was to compare inflammatory, clinical and spirometric patterns between children with asthma and obesity and those within the normal weight status range.
A total of 79 boys and girls from 6 to 10 years old were selected and divided into four groups obese asthmatics, non-obese asthmatics, obese non-asthmatics, and non-obese non-asthmatics. MAPK inhibitor In addition to collecting clinical and anthropometric data, all children underwent spirometry and skin prick tests for inhalant allergens. Blood samples for measurement of cytokines and adipokines were also collected.
Obese asthmatics had significantly worse control of asthma than non-obese asthmatics (OR 4.9; 95%CI 1.1‒22.1), regardless of sex, physical activity and atopy. No differences in spirometry, Th1 and Th2 cytokines and adipokines levels were observed among the four groups. The prick tests were positive in 81.8 and 80% of non-obese asthmatics and obese asthmatics, respectively.
The degree of control of asthma was significantly lower in the obese group, regardless of the findings of no differences in spirometry. Extra-pulmonary factors could be responsible for this symptomatic profile. High positivity of skin test in both groups, which is considered a good marker of atopy, shows a preponderant atopic component in the genesis of asthma, both in children with obesity and in those within the normal weight status.

To evaluate the influence of dental trauma on oral health-related quality of life (OHRQoL) of children and their families.
A total of 571 children aged five years were randomly selected at public schools. Trauma was clinically evaluated in accordance with the Andreasen classification. Caries experience in the anterior region and increased overjet were determined according to the World Health Organization criteria. The Early Childhood Oral Health Impact Scale (ECOHIS) was answered by the parents and used to evaluate OHRQoL. In addition, this questionnaire has aspects related to socioeconomic status. Simple logistic regression was performed, and the raw Odds Ratios with the respective 95% confidence intervals (95%CI) were estimated. The variables with p<0.20 were tested in multiple logistic regression models, and those with p≤0.05 remained in the model and the adjusted odds ratio with respective 95%CI was estimated.
Income showed a magnitude of association of 1.56 and 2.70 with the OHRQoL of children and families, respectively.
