Nutritional status and dental caries of vulnerable Cambodian children and adolescents living in Phnom Penh
During childhood, malnutrition is associated with dental caries, being the most prevalent oral disease in Cambodian. Therefore, this cross-sectional study investigated the nutritional status and the prevalence of dental caries in 344 vulnerable Cambodian children and adolescents aged 6 to 18 years old. Nutritional status (body weight, height and body mass index-for-age and sex) and the DMFT index (decayed-missing-filled teeth) were measured and calculated. Results showed that most participants presented normal weight (56.7%), 36.6% were underweight, 6.7% were overweight and 45.1% were stunted. Dental caries prevalence was remarkably high (94.9%) with children aged 6-11y-old presenting a significantly higher DMFT index (6.7 ± 4.0) than adolescents (4.0 ± 2.9 for 12-14y and 4.1 ± 1.6 for 15-18y, P < 0.01). Children suffering from underweight showed the highest DMFT index (6.6 ± 3.8). In conclusion, vulnerable and at-risk children aged 6-11y-old and underweight were the most affected; therefore, prevention is urgent, especially nowadays. Nutritional and oral health literacy should be encouraged.publishersversionpublishe
FAAH rs324420 Polymorphism Is Associated with Performance in Elite Rink-Hockey Players
Funding Information: This research was supported by research found ICBAS-PDBiomedical Sciences-200203100 and Portuguese League Against Cancer—Northern Branch (LPCC-NRN).Genetic factors are among the major contributors to athletic performance. Although more than 150 genetic variants have been correlated with elite athlete status, genetic foundations of competition-facilitating behavior influencing elite performances are still scarce. This is the first study designed to examine the distribution of genetic determinants in the athletic performance of elite rink-hockey players. A total of 116 of the world’s top best rink-hockey players (28.2 ± 8.7 years old; more than 50% are cumulatively from the best four world teams and the best five Portuguese teams), who participated at the elite level in the National Rink-Hockey Championship in Portugal, were evaluated in anthropometric indicators/measurements, training conditions, sport experience and sport injuries history. Seven genetic polymorphisms were analyzed. Polymorphism genotyping was performed using the TaqMan® Allelic Discrimination Methodology. Rink-hockey players demonstrated significantly different characteristics according to sex, namely anthropometrics, training habits, sports injuries and genetic variants, such as Vitamin D Receptor (VDR) rs731236 (p < 0.05). The Fatty Acid Amide Hydrolase (FAAH) rs324420 A allele was significantly associated with improved athletic performance (AA/AC vs. CC, OR = 2.80; 95% Cl, 1.23–6.35; p = 0.014; p = 0.008 after Bootstrap) and confirmed as an independent predictor among elite rink-hockey players (adjusted OR = 2.88; 95% Cl, 1.06–7.80; p = 0.038). Our results open an interesting link from FAAH-related biology to athletic performance.publishersversionpublishe

Chemical composition, antibacterial and antioxidant activities of the essential oil from Vismia guianensis fruits
In recent decades, the essential oils of plants have drawn great interest as sources of natural products. Essential oil from the fruits of Vismia guianensis was tested for its chemical constituents and antimicrobial and antioxidant activities. Gas chromatography/mass spectrometry (GC-MS) analysis of the essential oil revealed the presence of 38 sesquiterpenoids. The major components were β-caryophyllene (25.8%), α-copaene (13.1%), and δ-cadinene (11.6%). Antimicrobial activities were measured against six species of Gram negative and seven species of Gram positive bacteria and showed antibacterial activity against the human pathogenic Gram-positive bacteria Staphylococcus lentus with minimum inhibitory concentration (MIC) values of 78 μg/ml. The antioxidant activity of the essential oil was evaluated using the beta carotene/linoleic acid assay and showed antioxidant activity.Key words: Vismia guianensis, chemical composition, antibacterial, antioxidant, fruits, essential oil
Parental Perception of Their Child’s Weight Status in Portugal: An Observational Study
Introduction: Parental perceptions of a child’s weight status may influence family readiness to foster healthy behaviors. Our aim was to observe parental perceptions of their child’s weight status in two time periods and in multiple population subgroups.
Methods: Data were collected in two national projects, 2009 - 2010 (n = 6577) and 2016 - 2017 (n = 7594), in public and private kindergartens and primary schools in Portugal (children aged three to 10 years old). Parents filled out a questionnaire regarding their perception of their child’s weight status, namely: 1) too thin, 2) thin, 3) normal weight, 4) with some excess weight, or 5) with a lot of excess weight. Children’s height and weight were objectively collected, and the International Obesity Task Force cut-offs were used to classify overweight and obesity. Accurate and misclassification levels were calculated for children according to their sex, age, as well as child and parental weight status, while considering differences within and between the two time periods.
Results: Overall, accuracy in parental perception of their child’s weight was higher in 2016 - 2017 than in 2009 - 2010, regardless of children’s sex, age, parental weight status, and education (65.7% and 60.5%, respectively). However, the ability of parents to detect obesity was ~ 50% lower in 2016 - 2017 compared with 2009 - 2010.
Conclusion: Even though parental perception of their child’s weight was better in 2016 - 2017 than in 2009 - 2010 , the inverse result was found among children with obesity. Strategies are needed to encourage parents to improve their perception of the appropriate weight for their child
Population genomics of Bombus terrestris reveals high but unstructured genetic diversity in a potential glacial refugium
Ongoing climate change is expected to cause an increase in temperature and a reduction of precipitation levels in the Mediterranean region, which might cause changes in many species distributions. These effects negatively influence species gene pools, decreasing genetic variability and adaptive potential. Here, we use mitochondrial DNA and RADseq to analyse population genetic structure and genetic diversity of the bumblebee species Bombus terrestris (subspecies Bombus terrestris lusitanicus), in the Iberian Peninsula. Although this subspecies shows a panmictic pattern of population structure across Iberia and beyond, we found differentiation between subspecies B. t. lusitanicus and B. t. africanus, probably caused by the existence of barriers to gene flow between Iberia and North Africa. Furthermore, the results revealed that the Iberian Peninsula harbours a large fraction of B. terrestris intraspecific genetic variation, with the highest number of mitochondrial haplotypes found when compared with any other region in Europe studied so far, suggesting a potential role for the Iberian Peninsula as a glacial refugium. Our findings strengthen the idea that Iberia is a very important source of diversity for the global genetic pool of this species, because rare alleles might play a role in population resilience against human- or climate-mediated changes.info:eu-repo/semantics/publishedVersio
Polyethylene Glycol 35 as a perfusate additive for mitochondrial and glycocalyx protection in HOPE liver preservation
Organ transplantation is a multifactorial process in which proper graft preservation is a mandatory step for the success of the transplantation. Hypothermic preservation of abdominal organs is mostly based on the use of several commercial solutions, including UW, Celsior, HTK and IGL-1. The presence of the oncotic agents HES (in UW) and PEG35 (in IGL-1) characterize both solution compositions, while HTK and Celsior do not contain any type of oncotic agent. Polyethylene glycols (PEGs) are non-immunogenic, non-toxic and water-soluble polymers, which present a combination of properties of particular interest in the clinical context of ischemia-reperfusion injury (IRI): they limit edema and nitric oxide induction and modulate immunogenicity. Besides static cold storage (SCS), there are other strategies to preserve the organ, such as the use of machine perfusion (MP) in dynamic preservation strategies, which increase graft function and survival as compared to the conventional static hypothermic preservation. Here we report some considerations about using PEG35 as a component of perfusates for MP strategies (such as hypothermic oxygenated perfusion, HOPE) and its benefits for liver graft preservation. Improved liver preservation is closely related to mitochondria integrity, making this organelle a good target to increase graft viability, especially in marginal organs (e.g., steatotic livers). The final goal is to increase the pool of suitable organs, and thereby shorten patient waiting lists, a crucial problem in liver transplantation
