Abstract Rationale Co-witness discussion is common and often witnesses are under the influence of alcohol. As such, it is important to understand how such factors may influence eyewitness testimony. Objectives We combined a co-witness memory paradigm with an alcohol administration paradigm to examine the influence of alcohol and dyadic discussion on remembering a mock crime. Methods Intoxicated and sober dyads discussed a previously seen video, whilst in a control condition sober and intoxicated individuals recalled the event on their own. Unknown to the dyads, each discussion partner saw a different version of the video including unique details not present in the other video version. All participants then engaged in a second individual recall attempt. Results Dyads were more likely to recall misleading details in their individual recall attempts compared to the control group. Intoxicated and sober dyads were equally likely to report misleading information. Alcohol intoxication had no negative impact on individuals’ ability to correctly identify the source of their responses. Intoxicated participants recalled fewer details under free recall conditions. Alcohol had a detrimental effect on participants’ confidence in their free recall accounts. Conclusions Possible alcohol-related and social-cognitive mechanisms are discussed which may contribute to the current findings as well as applied implications for interviewing intoxicated witnesses.

The research aimed at studying the mother’s social-hygienic and medical biological risk factors and determining their predictive value. The retrospective case-control study was conducted with 142 pregnant women participating in it. In the case group there were involved 92 mothers whose pregnancy was completed by the birth of a newborn baby suffering from the intrauterine growth restriction. The control group was made of 50 pregnant women, whose pregnancy was completed by the birth of a healthy neonate. The research resulted in specifying the risk factors of high priority: the low standards of living (OR 3.61), chronic stress (OR-3.06), sleeping disorder (OR-3.33) and poor nutrition (OR-3.81). As regards the coexisting pathology the following was revealed: endocrine pathology (OR-3.27), ischemic heart disease (OR-4.35), arterial hypertension (OR-6.47), iron deficiency anemia (OR-4.11), pathology of respiratory system (OR-3.42), chronic genital inflammatory and infectious processes. The preeclampsia (92%) and low amniotic fluid (89%) were detected to have the high predictive value. The awareness of risk factors allows us to employ the timely measures for the reduction of negative impact on the fetus and neonate.

AbstractSleep problems are frequently reported in infants treated with propranolol for infantile hemangiomas, possibly serving as a marker for a negative impact on central nervous system function. In this cohort study, we objectively investigate the sleep behavior of infants with infantile hemangiomas on propranolol compared to a healthy, untreated control group. Sleep of propranolol-treated infants and controls was investigated using ankle actigraphy and a 24-h diary for 7–10 days at ages 3 and 6 months. The main outcome measures were the Number of Nighttime Awakenings and Sleep Efficiency. The main secondary outcome measures included 24-hour Total Sleep, daytime sleep behavior, and parent-rated infant sleep quality and behavioral development based on the Brief Infant Sleep Questionnaire (BISQ) and the age-appropriate Ages-and-Stages Questionnaire (ASQ), respectively. Fifty-four term-born infants were included in each cohort. No group difference in any investigated parameter was seen at age 3 months. At age 6 months, the propranolol group exhibited a decrease in Sleep Efficiency and a trend towards an increased Number of Nighttime Awakenings compared to the control group. Treated infants at 6 months also had shorter daytime waking periods. 24-hour Total Sleep was unaffected by propranolol. No negative impact of propranolol on subjective sleep quality and behavioral development was noted.Conclusion: Propranolol exerts a measurable yet mild impact on objectively assessed infants’ sleep measures. Behavioral developmental scores were unaffected. Our results support propranolol as first-line therapy for complicated infantile hemangiomas. What is Known:• Sleep disorders are frequently reported in infants with infantile hemangiomas treated with propranolol and often lead to treatment discontinuation.• Investigations of the sleep pattern in this patient group using objective measures are lacking. What is New:• The sleep pattern of propranolol-treated infants is assessed using actigraphy and a 24-h sleep diary and compared to healthy, untreated controls.• Propranolol leads to a decreased sleep efficiency at night and an increased demand of daytime sleep, yet effects are mild overall.

Background. Language disorder is the most frequent developmental disorder in childhood and it has a significant negative impact on children’s development. The goal of the present review was to systematically analyze the effectiveness of interventions in children with developmental language disorder (DLD) from an evidence-based perspective. Methods. We considered systematic reviews, meta-analyses of randomized controlled trials (RCTs), control group cohort studies on any type of intervention aimed at improving children’s skills in the phono-articulatory, phonological, semantic-lexical, and morpho-syntactic fields in preschool and primary school children (up to eight years of age) that were diagnosed with DLD. We identified 27 full-length studies, 26 RCT and one review. Results. Early intensive intervention in three- and four-year-old children has a positive effect on phonological expressive and receptive skills and acquisitions are maintained in the medium term. Less evidence is available on the treatment of expressive vocabulary (and no evidence on receptive vocabulary). Intervention on morphological and syntactic skills has effective results on expressive (but not receptive) skills; however, a number of inconsistent results have also been reported. Only one study reports a positive effect of treatment on inferential narrative skills. Limited evidence is also available on the treatment of meta-phonological skills. More studies investigated the effectiveness of interventions on general language skills, which now appears as a promising area of investigation, even though results are not all consistent. Conclusions. The effectiveness of interventions over expressive and receptive phonological skills, morpho-syntactic skills, as well as inferential skills in narrative context underscores the importance that these trainings be implemented in children with DLD.

A modern school deals with a generation of students who were born and grown up in a digital environment and require other teaching methods. Changes in the technological and social conditions of modern society need new professional skills, which are often called “21st century skills”. These skills should be devel-oped starting from the primary school, as they are psychological and behavioural, rather than practical. Game-based learning and gamification are effective means of such skills development. The use of video games in teaching practice is studied multifaceted, along with formats and requirements of educational game, methods for effectiveness assessment, and the effect of games on students. The controver-sial nature of game-based learning effect on students require deeper research, as the increase in motivation and learning efficiency cannot be disputed, as well as the negative impact of a long gaming on cognitive abilities, emotional state and social skills of students. The study tested both an increase in the motivation and attraction of school students for the learning process, and the impact on the prac-tical results of information assimilation. There was conducted a survey on the re-sults of the application of game training to determine the motivation and attraction of students. Likewise, we counted time, spent by the study and control group, for mastering the main educational material and the post-class study of game content and the educational material it presents. A comparative test was conducted on the results of educational material comprehension to determine the effectiveness of the methodology in mastering knowledge. The group, with game-based learning and gamification applied, showed an increase in motivation and attraction to learning, students paid additional efforts for assimilating the material studied, and also showed significantly higher learning outcomes compared to the control group.

BACKGROUND: The negative impact of cognitive dysfunction on motor rehabilitation as a relearning-process is well known in stroke patients. However, evidence for combined cognitive and motor training (CMT) is lacking. OBJECTIVE: To evaluate the effects of combined CMT in early stroke rehabilitation. METHODS: In a controlled pilot study, 29 moderately affected stroke patients with low-level motor performance and cognitive impairment received motor therapy plus either cognitive (experimental group, EG) or low-frequency ergometer training (control group, CG) for eight days. RESULTS: Both groups improved their motor functioning significantly. After training, between-group comparison revealed significant differences for cognitive flexibility and trends for set-shifting, working memory, and reaction control in favor of the EG. Within-group effects showed improvement across all cognitive domains in the EG, which correlated with gains in bed-mobility, while the CG showed no significant improvement in cognition. Rather, a trend towards reaction control decline was observed, which correlated with less functional progression and recovery. Furthermore, a decline in cognitive flexibility, set-shifting, and working memory was descriptively observed. CONCLUSIONS: Combined CMT may enhance cognition and motor relearning early after stroke and is superior to single motor training. Further studies are needed to replicate these results and investigate long-term benefits.

Objectives: In this paper, the effects of tobacco on aerobic exercise ability and physical fitness recovery of college students were studied. Methods: University group sports intervention form: traditional characteristic project (basketball) + Taiji soft ball (R&D intervention project). Exercise time: 3 times/week; Activity duration: 30min; Activity intensity: the heart rate is controlled at 120-140 beats/min. All the college students in the experimental group are students who have never smoked, and the college students in the control group are students who have smoked for more than two years. The other conditions are the same. Results: The exercise time and endurance of experimental groups I and II were significantly lower than those of the control group, and the cardiopulmonary function was significantly lower than that of the control group. The indexes of experimental group II changed significantly compared with experimental group I, and the difference was statistically significant. Conclusion: Cigarette smoke can significantly reduce the aerobic exercise ability and anti fatigue ability. The longer the smoking time, the more serious the adverse effects. Therefore, tobacco smoke and nicotine will damage college students’ aerobic exercise ability and have a negative impact on the recovery of physical fitness after exercise.

BackgroundA disorder of self-monitoring may underlie the positive symptoms of psychosis. The cognitive mechanisms associated with these symptoms may also be detectable in individuals at risk of psychosisAimsTo investigate (a) whether patients with psychosis show impaired self-monitoring, (b) to what degree this is associated with positive symptoms, and (c) whether this is associated with liability to psychotic symptomsMethodThe sample included: individuals with a lifetime history of non-affective psychosis (n=37), a genetically defined risk group (n=41), a psychometrically defined risk group (n=40), and control group (n=49). All participants carried out an action-recognition taskResultsNumber of action – recognition errors was associated with psychosis risk (OR linear trend over 3 levels: 1.12, 95% CI 1.04–1.20) and differential error rate was associated with the degree of delusional ideation in a dose–response fashion (OR linear trend over 3 levels: 1.13, 95% CI 1.00–1.26)ConclusionsAlterations in self-monitoring are associated with psychosis with evidence of specificity for delusional ideation. In the risk state, this is expressed more as failure to recognise self-generated actions, whereas in illness failure to recognise alien sources come to the fore
