A system consisting of six SBR units was operated in parallel for three phases to investigate the impacts of salinity shock and anaerobic and aerobic starvation on the activated sludge process stability and effects of various recovery stimulation methods on the subsequent recovery period. Different recovery strategies were applied in each SBR unit, including natural recovery, adding bio-accelerators, a stepwise increase feed strategy, a stepwise strategy coupled with bio-accelerators dosing, extended aeration time, and extended aeration time coupled with bio-accelerators dosing. It was concluded that the combination of stepwise strategy and dosing bio-accelerators showed the most efficiency in boosting system recovery after being subjected to NaCl shock and starvation. The boosting effect of the stepwise strategy alone was slightly better in recovery after NaCl shock. Furthermore, extending the aeration rate could bring more positive effects when resuscitating the system after long-term anaerobic starvation. For the unit that only received dosing of bio-accelerators during the recovery period, it could be concluded that there was a specific time requirement for the bio-accelerators to take effect significantly, as the impact of bio-accelerators on the beginning days of recovery periods was very slight. In contrast, adjusting operational regimes such as stepwise increased feed volume or extending aeration time could significantly boost the SBRs from the first recovery days. Hence, highly effective recovery efficiency could be achieved by coupling dosing bio-accelerators with other operational adjustment methods, especially stepwise strategies.

The aim of this meta-analysis was to review the impact of a Paleolithic diet (PD) on selected health indicators (body composition, lipid profile, blood pressure, and carbohydrate metabolism) in the short and long term of nutrition intervention in healthy and unhealthy adults. A systematic review of randomized controlled trials of 21 full-text original human studies was conducted. Both the PD and a variety of healthy diets (control diets (CDs)) caused reduction in anthropometric parameters, both in the short and long term. For many indicators, such as weight (body mass (BM)), body mass index (BMI), and waist circumference (WC), impact was stronger and especially found in the short term. All diets caused a decrease in total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG), albeit the impact of PD was stronger. Among long-term studies, only PD cased a decline in TC and LDL-C. Impact on blood pressure was observed mainly in the short term. PD caused a decrease in fasting plasma (fP) glucose, fP insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) and glycated hemoglobin (HbA1c) in the short run, contrary to CD. In the long term, only PD caused a decrease in fP glucose and fP insulin. Lower positive impact of PD on performance was observed in the group without exercise. Positive effects of the PD on health and the lack of experiments among professional athletes require longer-term interventions to determine the effect of the Paleo diet on athletic performance.

UK military personnel have faced increased demands over the last three decades; these have affected their wellbeing and caused multiple physical and mental health problems. Currently, bespoke rehabilitation systems may recommend participation in sports programmes. Although research attention has been drawn to the short-term positive effects of these programmes, their long-term impact on psychological wellbeing is unknown. To address this gap, the current study explored the long-term impact of a sports programme on UK military personnel’s ability to make changes in their day-to-day life through the lens of psychological wellbeing. For this purpose, UK military personnel (n = 97) completed an online survey aiming to provide a quantitative and qualitative picture of their experiences of an outdoor and adventure sports programme, underpinned by the basic psychological needs theory, six months following completion. Findings suggest that 75% of respondents found that the course was useful for facilitating adaptive changes. Content analysis suggests that elements of the course seem to satisfy their basic psychological needs of competence, relatedness and autonomy. Activities initiated six months after the course are mostly aligned with improved psychological wellbeing. Useful theoretical and applied implications are discussed.

(1) Background: Self-talk (ST) is used to influence athletes’ thoughts, feelings, and behaviors. Samples of squad and competitive athletes are underrepresented, although research has proven the positive effects of ST in the context of sports. Thus, the present study focused on the impact of ST on psychological and performance outcomes of junior sub-elite athletes. (2) Methods: N = 117 athletes (55 females, 62 males; M = 16.0 years) were randomly assigned to either one of two experimental groups or to a control group (n = 30). The experimental groups received an ST intervention for either one week (n = 36) or eight weeks (n = 38), and the control group received no ST training. The dependent variables (competitive anxiety, volitional skills, self-efficacy, and coaches’ performance ratings) were assessed three times before and after the intervention. It was expected that (a) an ST intervention would reduce the competitive anxiety and increase volitional skills, self-efficacy, and performance; and, (b) long-term training would lead to higher effects than short-term training. (3) Results: As expected, ST training led to (less) somatic state anxiety and (higher) state self-confidence, self-optimization, self-efficacy, and performance. Additionally, long-term training was more effective than short-term training. (4) Conclusions: Targeted ST interventions may help to improve junior athletes’ psychological states and performance.

Structural and functional brain alterations as well as cognitive deficits are well-documented findings in schizophrenia patients. Cognitive impairments affect the long-term outcome of schizophrenia and are the main contributors to disability. Despite their clinical impact, however, no effective options are available to treat them sufficiently. Aerobic endurance training has been shown to have effects on brain plasticity, gray and white matter volume as well as functional connectivity measures and on cognitive functioning in animal models and healthy humans. However, effects of physical exercise in combination in combination with cognitive remediation are unknown in Schizophrenia. 21 chronic schizophrenia patients and 21 age and gender–matched healthy controls underwent 3 months of aerobic exercise (endurance training, 30 min, 3 times per week). 21 additionally recruited schizophrenia patients played table soccer (known as “foosball” in the USA) over the same period. After 6 weeks of endurance training or table soccer, all participants commenced standardized cognitive training with a computer-assisted training program. We could show that a 3-month endurance-training program combined with CR therapy had positive effects on everyday functioning in multi-episode Schizophrenia patients. Deficits improved from medium to mild as assessed with the GAF. Negative symptoms, short and long-term verbal memory and cognitive flexibility also improved with training. We could demonstrate grey matter volume increase in the left temporal lobe in schizophrenia patients undergoing endurance training. A non-endurance and coordinative training stimulus like playing table soccer led to a clearly distinct pattern of grey matter alterations in Schizophrenia patients.Disclosure of interestThe author declares that he has no competing interest.

The Impact

Particular concern at the present stage is the health effects of wildfires’ smoke. The aim of the study was to determine the impact of paternal biomass-smoke exposure on offspring’s behavior and cognitive abilities. Male rats were exposed to biomass smoke for four hours/day, five days/week, for four weeks. Average concentration of carbon monoxide and particulate matter of 2.5 μm PM2.5 in the chamber during exposure were 28.7 ± 5.3 mg/m3 and 1.9 ± 0.5 mg/m3, respectively. At the same time, high concentrations of furfural and acetaldehyde were detected in the air environment of the exposure chambers. Offspring was obtained by mating of experimental males with untreated females, immediately after the end of the exposure and after 60 days (long-term period). Offspring were tested by using the Morris water maze and open field at three months of age. Male and female offspring born by mating immediately after exposure demonstrated decreased exploratory behavior, locomotor activity, and spatial navigation, as well as increased anxiety levels. Locomotor and exploratory activity in rats of both sexes from progeny obtained after long-term exposure to smoke had no statistically significant differences when compared to the control; however, the females showed a high level of anxiety and impaired cognitive functions. The recovery period after biomass-smoke intoxication, comparable in duration of spermatogenesis in rats, was an important factor in reducing the risk of developing central nervous system (CNS) disorders in offspring.

The Impact

Following the outbreak of COVID-19, multidisciplinary research focusing on the long-term effects of the COVID-19 infection and the complete longer term recovery is still scarce. With regards to long-term consequences, biomarkers of physiological effects as well as the psychological experiences are of significant importance for comprehensively understanding the whole COVID-19 recovery period. The present research surveys the IgG antibody titers and the impact of COVID-19 as a traumatic experience in the aftermath of the active infection period, around two months after diagnosis, in a subset of COVID-19 patients from the first wave of the outbreak in Northern Cyprus. Associations of antibody titers and psychological survey measures with baseline characteristics and disease severity were explored, and correlations among various measures were evaluated. Of the 47 serology tests conducted for presence of IgG antibodies, 39 (83%) were positive. We identified trends demonstrating individuals experiencing severe or critical COVID-19 disease and/or those with comorbidities are more heavily impacted both physiologically and mentally, with higher IgG titers and negative psychological experience compared to those with milder disease and without comorbidities. We also observed that more than half of the COVID-19 cases had negative psychological experiences, being subjected to discrimination and/or verbal harassment/insult, by family/friends. In summary, as the first study co-evaluating immune response together with mental status, our findings suggest that further multidisciplinary research in larger sample populations as well as community intervention plans are needed to holistically address the physiological and psychological effects of COVID-19 among the cases in the long-term.

Abstract COVID-19 has brought to the forefront of academic debates the consequences of pandemics and their appropriate policy responses. Using the PRISMA methodology, we provide a comprehensive review of the economic and historical analysis of the long-term economic consequences of pandemics. Mainstream economists focus on the impact of pandemics on production factors, finding a rich but contrasting set of mechanisms with overall negative or insignificant effects. Historians focus on the institutional impact, finding positive effects of pandemics when they trigger new socioeconomic arrangements. Evolutionary economists can integrate into the economic debate both historical elements and the complex biological characteristics of pandemics. We argue that the evolutionary approach provides new and fertile theoretical foundations to understand the phenomenon and develop effective policies.

Canine Therapy

The goal of our research is to investigate the impact of canine therapy on the development of children with learning disabilities, with special regard to social and emotional competence. The research question was: to what extent does intensive animal-assisted therapy influence the behaviour of the pupils enrolled in the sample, and can the long-term effects of the therapy be demonstrated and justified? To explore the longitudinal study over six months, a qualitative and quantitative test method was used. As a research tool, we used the Conners Questionnaire on Child Behaviour, which was revealed by descriptive and mathematical statistical analysis. Owing to the multi-focus study, the positive effects of canine therapy were confirmed from several sides. Based on the results we can prove that the canine therapy positively and lastingly influenced the behaviour of the examined children, which showed a positive change in several areas.

The Impact

The article describes the impact of technological devices – gadgets – on the early cognitive and speech development in children. In early childhood, object-activity communication is the leading form of activity; its influence on the speech development is determined by the interaction of the child with the adult (object-oriented actions, the understanding of the purpose of objects, the use of verbal communication). The play activity of preschoolers helps to enhance communication and interaction with peers. Long and uncontrolled interaction with gadgets is connected with insufficient attention of parents and caregivers, which disrupts the process of communication and cognition, in particular, slows down the process of speech development. Foreign pediatric associations recommend eliminating the use of mobile devices in children aged 0–2 years and limiting their use to one hour per day for children aged 3–5 years. Most researchers identify a connection between the long-term use of gadgets by preschoolers, delayed development of endogenus attention, social interaction, distortion of cognitive development, delayed speech development and such positive effects as a high level of exogenus attention development, quick response to external stimuli.

The Impact

This review provides an overview of the literature regarding digital technology use and adolescent well-being. Overall, findings imply that the general effects are on the negative end of the spectrum but very small. Effects differ depending on the type of use: whereas procrastination and passive use are related to more negative effects, social and active use are related to more positive effects. Digital technology use has stronger effects on short-term markers of hedonic well-being (eg, negative affect) than long-term measures of eudaimonic well-being (eg, life satisfaction). Although adolescents are more vulnerable, effects are comparable for both adolescents and adults. It appears that both low and excessive use are related to decreased well-being, whereas moderate use is related to increased well-being. The current research still has many limitations: High-quality studies with large-scale samples, objective measures of digital technology use, and experience sampling of well-being are missing.
