The Effects of the Dark Triad Traits on the Five Pillars of Positive Psychology: The Moderation Effect of Gender

The current study investigated the effects of the Dark Triad traits (Machiavellianism, narcissism, and psychopathy) on mental health indicators from the viewpoint of positive psychology. Additionally, the moderation effect of gender was explored in the context of these relationships. The sample consisted of Hungarian adults from Serbia (439, 54% women). The participants completed the Short Dark Triad Scale (SD3) and the Mental Health Test (MHT), which is a new measure of mental health that can identify levels of well-being, savoring, creative and executing efficiency, self-regulation, and resilience. Results showed that narcissism positively predicted all mental health indicators, while psychopathy negatively predicted all indicators, except for resilience, with which it showed no significant relationship. Machiavellianism was a positive predictor of savoring, creative and executing efficiency, but a negative predictor of self-regulation and resilience and it had no significant effect on well-being. There was no significant moderation effect of gender.

Fungal and seed treatment interference in the viability of coriander seeds

ABSTRACT The determination of the sanitary quality is important to diagnose if the commercialized lots are free of pathogens and to make a decision about the need for seed treatment. The objective was to evaluate the interference of fungi associated with coriander seed lots in their physiological performance and the effect of seed treatment with the fungicide Metalaxyl-m + Fludioxonil. The study was carried out in two steps. In experiment I, the physiological potential and sanitary characterization of 18 coriander seed lots were evaluated, using the tests, water content, tetrazolium test and health test. In experiment II, we evaluated the physiological performance of coriander seeds with and without fungicide treatment using the first count and germination test. Coriander seed lots showed high physiological potential, however, not all lots expressed their maximum potential in the germination test without treatment, due to the negative effect of fungi associated with seeds, mainly A. dauci and in association with A. alternata. There was an improvement in the physiological performance of coriander seeds treated with Metalaxyl-m + Fludioxonil fungicide.

This gives rise to the necessity of disruptive technologies such as Blockchain. In this paper, we provide an overview of the Hyperledger and Ethereum platforms and present how healthcare organizations can control and monitor digital health test certificates with citizens or other stakeholders. We also present a smart contract structure and implementation for COVID-19 test certificates in both blockchain platforms.

544 - Validation of a new cognitive screening tool, the Brain Health Test-7, for identification of mild cognitive impairment and early dementia in 3 differentkinds of hospital settings

BackgroundThe Brain Health Test-7 (BHT-7) is a revised tool from the original BHT, containing more tests about frontal lobe function. It was developed with theaim of identifying patients with mild cognitive impairment (MCI) and early dementia.Research objectiveHere we report the validity of the BHT-7 versus the Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) in differentpsychiatry or neurology clinics.MethodsPatients with memory complaints were recruited in this study from the outpatient clinic of psychiatry or neurology in 3 different kinds of hospitals. Allpatients underwent the evaluation of the BHT-7, MMSE, MoCA, and clinical dementia rating (CDR). The clinical diagnosis (normal, MCI, dementia) was made by consensus meeting, taking into account all available data.Demographic data and the scores of the MMSE, MoCA, and BHT-7 between groups were compared. Logistic regression was adopted for analysis of optimal cutoff values, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), receiver operating characteristic (ROC) curve,and the area under the ROC curve (AUC).ResultsWe enrolled a total of 1090 subjects (normal 402, MCI 317, dementia 371); of them, 705 (64.7%) were female. There was a statistically significant differencein age, years of education, and 3 cognitive test scores among the 3 groups.Compared with the MMSE and MoCA, the BHT-7 performed slightly betterthan MMSE and MoCA in differentiating MCI or dementia from the normalcontrols (Table 1). For BHT- 7, the cutoff point was 17 between normal andMCI, and 14 between normal and dementia. These cutoff points for BHT-7were consistent through 3 different clinical settings, but inconsistent for MMSE and MoCA. The testing time for the BHT-7 was about 5-7 minutes, shorter than that of the MMSE and MoCA.ConclusionCompared with MMSE and MoCA, the BHT-7 showed slightly better performance in differentiating normal from MCI or dementia subjects. The testing time for the BHT-7 was shorter, and its cutoff points were consistent through different outpatient clinic settings. The results support that BHT-7 is auseful cognitive screening tool for MCI or early dementia in various hospital settings.Table 1Comparisons of the performance of BHT-7, MMSE, MoCAAUCcutoffSENSPEPPVNPVNormal vs. MCIBHT-70.8532≦170.81700.74130.71350.8371MMSE0.8061≦270.79500.68830.66840.8091MoCA0.8316≦250.82020.67910.66840.8273Normal vs. DementiaBHT-70.9848≦140.94340.96020.95630.9484MMSE0.9693≦240.88950.96260.95650.9040MoCA0.9768≦210.92450.94280.93720.9312Normal vs. MCI + DementiaBHT-70.9241≦160.83720.84580.90280.7522MMSE0.8941≦250.72820.91520.93650.6625MoCA0.9099≦230.80810.85320.90410.7221

The potential of SARS-CoV-2 antigen-detection tests in the screening of asymptomatic persons

Objectives: To assess the performance of antigen-based rapid diagnostic tests (Ag-RDTs) for SARS CoV-2 when implemented for large-scale universal screening of asymptomatic individuals. Methods: This study presents data from a pragmatic implementation study for universal Ag-RDT-based screening at a tertiary care hospital in Germany where all incoming patients without symptoms suggestive of SARS-CoV-2 were screened with an Ag-RDT prior to admission since October 2020. Results: In total, 49,542 RDTs were performed in 27,199 asymptomatic individuals over a duration of five months. Out of 222 positive results, 196 underwent in-house confirmatory testing with PCR, out of which 170 were confirmed positive, indicating a positive predictive value (PPV) of 86.7%. Negative Ag-RDTs were not routinely tested with PCR, but a total of 94 cases of false negative Ag-RDTs were detected due to PCR tests being performed within the following five days with a median CT-value of 33. Conclusions: This study provides evidence that Ag-RDTs can have a high diagnostic yield for transmission relevant infections with limited false-positives when utilized at the point of care on asymptomatic patients and thus can be a suitable public-health test for universal screening.

Development of an oral swab based microbiome test for the detection of feline dental disease

Variations in the microbial composition of the mouth (the oral microbiome) have known associations with dental and systemic disease. While this is relatively well understood in humans, research on this topic in companion animals, and in cats in particular, has been limited. In this study, we used oral microbiome data obtained from shotgun metagenomic sequencing of 38,000 cats (data gathered through a direct-to-consumer cat DNA testing platform) to reveal the staggering diversity of the feline oral microbiome, identifying 8,344 microbial species across the entire cohort. We used a subset of these data points (6,110 cats) to develop a feline dental health test able to assess whether a cat is at risk of having periodontal disease, tooth resorption and halitosis based on their oral microbiome. After filtering out classified microbial reads with low abundance, we were able to detect, on average, 606 microbes per oral microbiome sample, identifying not just bacteria, but also viruses, fungi, archaea and protozoa. Due to the shortage of available published research on the microbial signature of tooth resorption and halitosis in cats, we used our periodontal disease feline cohort (n=570) to validate our approach. We observed microbial compositional abundance trends consistent with previously reported findings from feline, canine and human studies on periodontal disease. We used compositional abundance-based statistical methods relying on pairwise log-ratio (PLR) transformation to identify microbes significantly correlated with each of the three dental conditions of interest. We identified a set of 27 microbes that are predictive for all three dental conditions, as well as microbes specifically predictive of periodontal disease, tooth resorption or halitosis. We used the compositional abundance profiles of predictive microbes to develop a risk score based model assessing the probability that a cat is suffering from each of the three dental conditions. The model had highest sensitivity for halitosis (72%) and highest specificity for tooth resorption (78%). Lastly, we observed relatively consistent dental disease risk profiles when we compared data from sample collection methods targeting the whole mouth versus those targeting the gum line specifically. In contrast, samples collected in triplicates from the same cats using a sampling method targeting the whole mouth showed more variation in the generated risk profiles. This was likely due to a failure to consistently collect sufficient sample material from areas of the mouth where microbes relevant to dental pathology would be found in highest amounts (i.e., the gum line). For this reason, we have modified the instructions of the test to emphasize the importance of targeting the gum line during sample collection. Regular at home or in clinic screening with the feline dental health test described in this study has the potential to facilitate early detection and prevention of dental disease.

Atividade antifúngica de óleos essenciais em sementes de Enterolobium contortisiliquum

<p><span class="fontstyle0">The objective of this work was to evaluate the efficiency of essential oils in sanitary and physiological quality in seeds of Enterolobium contortisiliquum. The experiment was carried out at Universidade Federal da Paraíba. The monkfish seeds were manually benefited and scarified to overcome dormancy. Ten treatments were used: control, dicarboximide fungicide and essential oils of Andiroba, eucalyptus, camphor, mint, fennel, basil, rosemary and Copaiba. A health test was performed, with incubation in filter paper, using as a criterion to identify the comparison of characteristics described in the specific literature. The germination test was evaluated up to the fourteenth day, and the variables analyzed were: germination percentage, first count, germination speed index, dead seeds, aerial part length, root and seedling, and fresh and dry matter of seedling. The experimental design used was DIC and the averages were compared using the Scott-Knott test. The essential oils of mint and fennel showed an efficiency equivalent to the conventional method with the use of fungicide and did not cause physiological damage. The essential oil of copaiba should not be used in the treatment of E. Contortisiliquum seeds because they are fungal stimulants and may cause damage to the physiological quality.</span><br /><br /></p>
