Journal Article
The coronavirus disease (COVID-19) pandemic forced the home confinement of the majority of population around the world, including a significant number of children and adolescents, for several weeks ...in 2020. Negative psychological effects have been identified in adults, but research about the impact of this type of social distancing measure on children and adolescents is scarce. The present study aimed to describe and compare the immediate psychological and behavioral symptoms associated with COVID-19 quarantine in children and adolescents from three southern European countries with different levels of restrictions (Italy, Spain, and Portugal). Parents of 1,480 children and adolescents (52.8% boys) between 3 and 18 years old (M = 9.15, SD = 4.27) participated in the study. An online survey using snowball sampling techniques was conducted during 15 days between March and April 2020, representing the early phase of the quarantine associated with COVID-19 outbreak. Parents answered questionnaires about sociodemographic data, housing conditions, immediate psychological responses during quarantine (e.g., anxiety, mood, sleep, and behavioral alterations), patterns of use of screens, daily physical activity, and sleep hours before and during the quarantine. The results revealed an increase in children's psychological and behavioral symptoms, increased screen-time, reduced physical activity, and more sleep hours/night. Italian children presented less psychological and behavioral symptoms compared with Portuguese and Spanish children. In general, hierarchical multiple regressions revealed that having an outdoor exit in the house (e.g., garden, terrace) contributed to lower levels of psychological and behavioral symptomatology. Future studies are needed to identify family and individual variables that can better predict children and adolescents' well-being during and after quarantine. Recommendations for families and implications for practice are discussed.
Introduction. The intestinal microbiocenosis is the most complex and important biotope of the body formed in the process of individual development. Material and methods. The study was conducted on ...groups of 20-25-day-old chicks. The first group was housed under standard vivarium conditions with artificially maintained optimal climatic parameters. The second group was raised in a rural homestead in the Kyiv region, on pasture with access to water, and fed twice daily with a blend of grains supplemented with kitchen wastes. Samples of chicken droppings (10 per group) were analyzed according to current international ISO standards using certified nutrient media and equipment. Results. Escherichia coli, Klebsiellas spp., Enterococcus spp. were isolated from 100% of samples from chickens kept in simulated conditions of an industrial poultry house, and Pseudomonas aeruginosa was isolated from 70% of samples. Escherichia coli and Enterococcus spp. were isolated from free-range chickens in 100% of cases. The analysis revealed that in pasture-raised chickens, Klebsiella spp. and Pseudomonas aeruginosa were absent from the litter, with significantly higher levels of normal microflora (Enterococcus spp.). Conclusions. Backyard-raised chickens showed no pathogenic zoonotic bacteria, in contrast to those raised under controlled conditions with optimal climate and standard diets. Висновки. Виявлено відмінності у складі індикаторних бактерій курячого посліду за різних умов утримання. Встановлено відсутність патогенних зоонозних бактерій у курей в умовах подвірного утримання, на відміну від курей, які утримувалися в умовах штучного забезпечення оптимальних кліматичних умов на стандартному раціоні.
The results of the study of the effect of cord blood serum and “Actovegin” (Takeda, Ukraine) on the reproductive function of cows in a comparative aspect are presented.
The aim of the study was to ...analyze the effect of cord blood serum and Actovegin on the reproductive function of uterine cows in a comparative aspect.
Materials and methods. The research was conducted during 2017-2020 in four dairy farms of Sumy region with tethered and untied maintenance. In 128 cows of different breeds and productivity, the timing of sexual cycling was studied and analyzed in comparison with the spontaneous sexual cycle with the use of cord blood serum and the drug "Actovegin" (Takeda, Ukraine).
Results. It was found that in cows with tethered content, the number of days from the introduction of 15 ml of cord blood serum to the manifestation of the excitation stage was significantly less compared to the spontaneous manifestation of sexual desire (5.63±0.36 and 14.38±2.1, respectively).
When cows with loose content were administered 10 ml of cord blood serum in combination with the drug "Actovegin", the number of days before the manifestation of sexual cycling was lower by 18.3 % compared with the rate of spontaneous sexual desire (4.31±0.38 and 18.25±1.89, respectively).
Conclusions. As a result of using 10 ml of cord blood serum in combination with the drug "Actovegin", in cows of different productivity and under different housing conditions, the number of days before the onset of the stage of arousal is significantly reduced compared to the spontaneous manifestation of sexual desire.
Cows of different productivity and with different housing conditions come to the sexual desire significantly faster with the use of 15 ml of cord blood serum compared to the spontaneous manifestation of sexual desire.
Poor home sanitation can increase the risk of stunting in children. The study aims to analyze the risk factors for stunting based on house conditions, sanitation facilities, and occupant behavior. ...Observational research using a case-control study design was carried out in September–December 2020. The sample size was 60 toddlers (30 cases and 30 controls) taken randomly by simple arithmetic. Case samples are stunted toddlers based on e-PPGBM data. The control sample is a typical toddler who is the closest neighbor to the case with age equivalence. Respondents were mothers of toddlers. Data on the physical condition of the house and sanitation facilities were obtained through direct observation, while data on the behavior of the house occupants were obtained through interviews. Data processing was carried out by cleaning and editing, coding for categorical variables, entry and data processing. Data were analyzed using the Chi-square test and odds ratio at 95% CI. The house's physical condition (p= 0,058; OR= 8,83) and the behavior of the householder in managing sanitation are risk factors for stunting (p= 0,002; OR= 6,91). In conclusion, toddlers who live in houses with physical conditions that do not meet health requirements are at risk of experiencing stunting 8,83 times. Residents of houses whose behavior does not meet sanitation requirements risk 6,91 times experiencing stunting in toddlers.
This study examined whether cumulative exposure to poor housing conditions is negatively associated with psychological well-being, and whether this association varies by age.
Using fifteen waves of ...the Korean Welfare Panel Study between 2005 and 2019 (118,500 person-observations), this study employed fixed-effects regression models to account for unobserved individual-level heterogeneity. Exposure to poor housing conditions ranged from 1 to more than 5 annual waves. To formally test for age heterogeneity, interactive models were estimated.
The trajectories of change in psychological well-being associated with cumulative exposure to poor housing conditions were different between young and middle-aged adults and older adults. Among young and middle-aged adults, the levels of depressive symptoms increased in the first year of exposure but remained at a similar level since then. In contrast, with the persistence of poor housing conditions, older adults continued to develop greater depressive symptoms over time. Similar age differences were found for life satisfaction. As exposure to poor housing conditions accumulated, life satisfaction persistently declined among older adults, but not young and middle-aged adults.
This study suggests that cumulative exposure to poor housing conditions has more adverse psychological consequences for older adults than young and middle-aged adults.
•Ethological approach helps to understand the housing effects on rodent behaviors.•Effect of isolation rearing depends on social relationships with cagemates when isolated.•Isolation rearing during ...critical developmental period induces behavioral agitation.•Short-term isolation rearing disrupts social transmission of information between cagemates.
The aim of the present review is to discuss how housing conditions affect behavioral performance in laboratory rodents from an ethological view. Commonly used laboratory rodents such as rats and mice, are originally captured animals that largely retain species-typical natural behaviors, while have fully adapted to a laboratory setting after long-term domestication. Laboratory settings including caging and artificial group housing are a considerable ethological factor influencing rodents’ behaviors in commonly employed behavioral test paradigms, including emotional and defensive behaviors, learning and memory, and attention-related behaviors. Particularly, isolation rearing, single-housed in a cage, is referred to a deprivation of social relationships with cagemates, has a substantial impact on behavioral performance in laboratory rodents. In this review, we will fully examine the importance of caging related ethological factors, e.g., social relationships and its deprivation, which are essential for unraveling the nature of housing effect in laboratory rodents. These discussions regarding the housing conditions will provide valuable information for appropriately conducting behavioral studies and interpreting data of rodents’ behaviors in neuroscience.
The ability to investigate therapeutic interventions in animal models of neurodegenerative diseases depends on extensive characterization of the model(s) being used. There are numerous models that ...have been generated to study Alzheimer's disease (AD) and the underlying pathogenesis of the disease. While transgenic models have been instrumental in understanding AD mechanisms and risk factors, they are limited in the degree of characteristics displayed in comparison with AD in humans, and the full spectrum of AD effects has yet to be recapitulated in a single mouse model. The Model Organism Development and Evaluation for Late-Onset Alzheimer's Disease (MODEL-AD) consortium was assembled by the National Institute on Aging (NIA) to develop more robust animal models of AD with increased relevance to human disease, standardize the characterization of AD mouse models, improve preclinical testing in animals, and establish clinically relevant AD biomarkers, among other aims toward enhancing the translational value of AD models in clinical drug design and treatment development. Here we have conducted a detailed characterization of the 5XFAD mouse, including transcriptomics, electroencephalogram,
imaging, biochemical characterization, and behavioral assessments. The data from this study is publicly available through the AD Knowledge Portal.
Structural racism and individual discrimination contribute to racial inequalities in poor housing conditions in the United States. Less is known about whether and how structural racism and individual ...discrimination shape a parallel, but distinct, process that is also consequential for family wellbeing: experiencing housing unit maintenance delays. Maintenance delays transform acute problems into chronic stressors and increase exposure to physical hazards over time. Using the 2013 American Housing Survey, I examine racial/ethnic disparities in maintenance delays across non-Hispanic White, Black, Hispanic, Asian, and American Indian/Alaska Native renters. Given that 2.3 million low-income households rent using Housing Choice Vouchers (HCVs), a federal housing assistance program with requirements around repair timing, I also examine how renting with a voucher shapes maintenance delays. There are three principal findings. First, White renters are more likely to report timely repairs than either Black or Hispanic renters. Second, for Black renters, both structural racism experienced in rental markets and individual discrimination drive this disparity, whereas Hispanic renters’ diverging maintenance experiences are largely explained by pathways impacted by structural racism. Third, renting with an HCV is not associated with repair timeliness for any racial/ethnic group. Taken together, the findings suggest that racial/ethnic disparities in substandard housing emerge not only through unequal exposure to housing quality problems but also through unequal responses to these issues.
