Assessing nitrate groundwater hotspots in Europe reveals an inadequate designation of Nitrate Vulnerable Zones

Monitoring networks show that the European Union Nitrates Directive (ND) has had mixed success in reducing nitrate concentrations in groundwater. By combining machine learning and monitored nitrate concentrations (1992-2019), we estimate the total area of nitrate hotspots in Europe to be 401,000 km2, with 47% occurring outside of Nitrate Vulnerable Zones (NVZs). We also found contrasting increasing or decreasing trends, varying per country and time periods. We estimate that only 5% of the 122,000 km2 of hotspots in 2019 will meet nitrate quality standards by 2040 and that these may be offset by the appearance of new hotspots. Our results reveal that the effectiveness of the ND is limited by both time-lags between the implementation of good practices and pollution reduction and an inadequate designation of NVZs. Substantial improvements in the designation and regulation of NVZs are necessary, as well as in the quality of monitoring stations in terms of spatial density and information available concerning sampling depth, if the objectives of EU legislation to protect groundwater are to be achieved.

The interplay between climate change and ageing: A systematic review of health indicators

Climate change and rapid population ageing pose challenges for communities and public policies. This systematic review aims to gather data from studies that present health indicators establishing the connection between climate change and the physical and mental health of the older population (≥ 65 years), who experience a heightened vulnerability to the impacts of climate change when compared to other age cohorts. This review was conducted according to the PICO strategy and following Cochrane and PRISMA guidelines. Three databases (PubMed, Scopus and Greenfile) were searched for articles from 2015 to 2022. After applying inclusion and exclusion criteria,nineteen studies were included. The findings indicated that various climate change phenomena are associated with an elevated risk of mortality and morbidity outcomes in older adults. These included cardiovascular, respiratory, renal, and mental diseases, along with physical injuries. Notably, the impact of climate change was influenced by gender, socioeconomic status, education level, and age-vulnerability factors. Climate change directly affected the health of older adults through ambient temperature variability, extreme and abnormal temperatures, strong winds, sea temperature variability, extreme El Niño-southern Oscillation (ENSO) conditions and droughts, and indirectly by air pollution resulting from wildfires. This review presents further evidence confirming that climate change significantly impacts the health and well-being of older adults. It highlights the urgency for implementing effective strategies to facilitate adaptation and mitigation, enhancing the overall quality of life for all individuals.

An improved protocol for bacteria identification by MALDI-TOF MS directly from positive blood cultures

FASTinov® developed a rapid antimicrobial susceptibility test that includes the purification of a bacterial suspension directly from positive blood cultures (BC). In order to streamline laboratory workflow, the use of the bacterial suspension obtained through FASTinov® sample prep was tested for identification (ID) by matrix absorption laser deionization-time of flight mass spectrometry (MALDI-TOF MS) (Bruker) in 364 positive BC, and its accuracy assessed comparing with the MALDI-TOF MS ID of the next-day subcultured colonies. FASTinov sample prep was highly reliable for rapid ID directly from BC with proportion of agreement of 94.9% for Gram-positive and 96.3% for Gram-negative bacteria.

White matter network underlying semantic processing: evidence from stroke patients

The hub-and-spoke theory of semantic representation fractionates the neural underpinning of semantic knowledge into two essential components: the sensorimotor modality-specific regions and a crucially important semantic hub region. Our previous study in patients with semantic dementia has found that the hub region is located in the left fusiform gyrus. However, because this region is located within the brain damage in patients with semantic dementia, it is not clear whether the semantic deficit is caused by structural damage to the hub region itself or by its disconnection from other brain regions. Stroke patients do not have any damage to the left fusiform gyrus, but exhibit amodal and modality-specific deficits in semantic processing. Therefore, in this study, we validated the semantic hub region from a brain network perspective in 79 stroke patients and explored the white matter connections associated with it. First, we collected data of diffusion-weighted imaging and behavioural performance on general semantic tasks and modality-specific semantic tasks (assessing object knowledge on form, colour, motion, sound, manipulation and function). We then used correlation and regression analyses to examine the association between the nodal degree values of brain regions in the whole-brain structural network and general semantic performance in the stroke patients. The results revealed that the connectivity of the left fusiform gyrus significantly predicted general semantic performance, indicating that this region is the semantic hub. To identify the semantic-relevant connections of the semantic hub, we then correlated the white matter integrity values of each tract connected to the left fusiform gyrus separately with performance on general and modality-specific semantic processing. We found that the hub region accomplished general semantic processing through white matter connections with the left superior temporal pole, middle temporal gyrus, inferior temporal gyrus and hippocampus. The connectivity between the hub region and the left hippocampus, superior temporal pole, middle temporal gyrus, inferior temporal gyrus and parahippocampal gyrus was differentially involved in object form, colour, motion, sound, manipulation and function processing. After statistically removing the effects of potential confounding variables (i.e. whole-brain lesion volume, lesion volume of regions of interest and performance on non-semantic control tasks), the observed effects remained significant. Together, our findings support the role of the left fusiform gyrus as a semantic hub region in stroke patients and reveal its crucial connectivity in the network. This study provides new insights and evidence for the neuroanatomical organization of semantic memory in the human brain.

Effects of optogenetic silencing the anterior cingulate cortex in a delayed non-match to trajectory task

Working memory is a fundamental cognitive ability, allowing us to keep information in memory for the time needed to perform a given task. A complex neural circuit fulfills these functions, among which is the anterior cingulate cortex (CG). Functionally and anatomically connected to the medial prefrontal, retrosplenial, midcingulate and hippocampus, as well as motor cortices, CG has been implicated in retrieving appropriate information when needed to select and control appropriate behavior. The role of cingulate cortex in working memory-guided behaviors remains unclear due to the lack of studies reversibly interfering with its activity during specific epochs of working memory. We used eNpHR3.0 to silence cingulate neurons while animals perform a standard delayed non-match to trajectory task, and found that, while not causing an absolute impairment in working memory, silencing cingulate neurons during retrieval decreases the mean performance if compared to silencing during encoding. Such retrieval-associated changes are accompanied by longer delays observed when light is delivered to control animals, when compared to eNpHR3.0+ ones, consistent with an adaptive recruitment of additional cognitive resources.

Is There a Bias Towards Males in the Diagnosis of Autism? A Systematic Review and Meta-Analysis

Autism is more frequently diagnosed in males, with evidence suggesting that females are more likely to be misdiagnosed or underdiagnosed. Possibly, the male/female ratio imbalance relates to phenotypic and camouflaging differences between genders. Here, we performed a comprehensive approach to phenotypic and camouflaging research in autism addressed in two studies. First (Study 1 - Phenotypic Differences in Autism), we conducted a systematic review and meta-analysis of gender differences in autism phenotype. The electronic datasets Pubmed, Scopus, Web of Science, and PsychInfo were searched. We included 67 articles that compared females and males in autism core symptoms, and in cognitive, socioemotional, and behavioural phenotypes. Autistic males exhibited more severe symptoms and social interaction difficulties on standard clinical measures than females, who, in turn, exhibited more cognitive and behavioural difficulties. Considering the hypothesis of camouflaging possibly underlying these differences, we then conducted a meta-analysis of gender differences in camouflaging (Study 2 - Camouflaging Differences in Autism). The same datasets as the first study were searched. Ten studies were included. Females used more compensation and masking camouflage strategies than males. The results support the argument of a bias in clinical procedures towards males and the importance of considering a 'female autism phenotype'-potentially involving camouflaging-in the diagnostic process.

Auditory Test of Processing Speed: Preliminary validation of a smartphone-based test of mental speed

BACKGROUND

The Symbol Digit Modalities Test (SDMT) is a gold-standard measure of cognitive efficiency and processing speed for people with multiple sclerosis (PwMS) but relies on vision and oculomotor function.

OBJECTIVES

To develop and validate a new processing speed test with minimal memory involvement and no eye function requirements.

METHODS

We created an Auditory Test of Processing Speed (ATOPS). A total of 122 PwMS, of whom 33 were severely disabled (median Expanded Disability Status Scale 8.0) and 37 healthy volunteers (HVs), were enrolled. We assessed sensitivity to discriminate MS participants from HVs, convergent validity between ATOPS and SDMT, sensitivity to discriminate between cognitively impaired (CI) and cognitively preserved (CP) MS participants, and correlations with MS pathology (overall brain lesion burden). Acceptability was examined with completion rates and participant ratings of ATOPS.

RESULTS

ATOPS discriminated PwMS from HVs (d = 0.739-0.856), correlated with SDMT (|r| = 0.528-0.587), discriminated between CI and CP PwMS (d = 0.623-0.776), and correlated with lesion burden (r = 0.332-0.436). All groups indicated high favorability of ATOPS and severely disabled MS patients could be assessed by ATOPS more frequently than by SDMT (100% vs. 72.4% completion).

CONCLUSIONS

ATOPS is a novel, accessible, and acceptable cognitive processing speed test that may be useful in clinical and/or research settings.

A Qualitative Study on Dentists' Communication Approaches in Managing Fluoride-Hesitant Caregivers

OBJECTIVES

Guidelines on effective provider-led communication are available but may be underused in dentistry, even if such guidelines could help dentists manage complex clinical scenarios like topical fluoride hesitancy. The purpose of this study was to investigate current chairside communication approaches used by dentists with fluoride-hesitant caregivers.

METHODS

A 27-item semistructured interview script was developed and pretested with 3 dentists, revised, and finalized. One-on-one interviews were conducted with a purposive sample of pediatric dentists and general dentists from April to June 2020. Interviews were digitally recorded, transcribed, and analyzed to identify dentists' communication approaches used during clinical interactions with fluoride-hesitant caregivers. Thematic analyses identified themes and subthemes, and exemplary quotes were provided to illustrate each theme.

RESULTS

Twenty-seven dentists participated (21 pediatric dentists and 6 general dentists). The mean age of participants was 43.0 ± 8.2 y (range, 30-73). Most participants were women (88.9%), white (51.9%), and non-Hispanic (85.2%). Participants had been practicing dentistry for a mean of 13.2 ± 10.5 y (range, 2-40). There were 4 themes: leaving topical fluoride decisions completely up to the caregiver, educating the caregiver about fluoride, insisting that the caregiver accept fluoride, and engaging the caregiver and child.

CONCLUSION

Most communications approaches used by interviewed dentists to manage fluoride hesitancy in clinical settings are not evidence based. Future dental education efforts should ensure that trainees are exposed to and can demonstrate competency in appropriate, evidence-based patient-provider communication strategies.

KNOWLEDGE TRANSFER STATEMENT

The study highlights the need for dentists to apply evidence-based communication strategies when managing difficult clinical scenarios like fluoride hesitancy, which is important in optimizing dentist-patient trust.

Trajectories of social withdrawal and social anxiety and their relationship with self-esteem before, during, and after the school lockdowns

The closure of schools during the COVID-19 pandemic affected adolescents' social withdrawal and social anxiety. Yet, self-esteem may have acted as a protective factor during this period. This study aimed to compare the trajectories of social withdrawal and social anxiety before (Year 1), during (Year 2 and 3), and after (Year 4) the closure of schools imposed by the COVID-19-related lockdowns, and to investigate the association of self-esteem with these trajectories. Participants were 844 (50.6% boys) Portuguese adolescents (mean age 12.70 years, SD = 1.14). The Social and Emotional Competencies Evaluation Questionnaire (QACSE) was used to assess social withdrawal and social anxiety, while The Global Self-Esteem scale of the Self-Description Questionnaire II was used to measure self-esteem. Growth curve analysis showed that social withdrawal and social anxiety had more negative trajectories during the year in which the school closures occurred. In addition, adolescents reported higher social withdrawal after the lockdowns than before the pandemic. Higher self-esteem was associated with a more positive trajectory in social withdrawal. Therefore, the results showed the negative of impact of the closure of schools on adolescents' social anxiety and social withdrawal, and that self-esteem was a protective factor during these challenging and adverse events.

A scoping review of mobile apps for use with palliative patients in the context of home care

CONTEXT

Progress in mobile technology, especially the use of applications for mobile devices, can support the process of monitoring patients in palliative care (therapeutics), controlling symptoms, or providing self-care guidelines for the user, namely patients or caregivers.

OBJECTIVES

To map the available knowledge regarding the use of applications for mobile devices to support adult patients in palliative care at home.

METHODS

Literature review, based on the Joanna Briggs Institute model(s) for Scoping Review. All articles published until October 27, 2022, were identified in the electronic databases MEDLINE®, CINAHL®, Psychology and Behavioral Sciences Collection, Cochrane Library, and Scopus using the respective Boolean logical operators and key terms.

RESULTS

A total of 634 articles were identified, and a final 24 studies were included. Eleven mobile device applications were identified, demonstrating different aspects of design, use, and technological development. These have incorporated the most recent technology in their functionalities.

CONCLUSION

Mobile applications can be considered a viable and effective means of monitoring patients in palliative care. However, these applications must go beyond the academic scenario in which they were developed and move toward widespread use in practice, allowing the evaluation of the impact of this "new" intervention modality to understand their effectiveness and the application of best practices.

Academic Performance in Institutionalized and Noninstitutionalized Children: The Role of Cognitive Ability and Negative Lability

More research is needed to understand the factors that contribute to low academic achievement in institutionalized children. The aim of this study was to investigate the relationship between cognitive and emotion regulation skills and academic performance, by comparing institutionalized and noninstitutionalized Portuguese children. The sample comprised 94 participants (46 institutionalized (22 boys) and 48 noninstitutionalized (23 boys) children), aged between 6 and 10 years, matched for age and sex. We used Raven's Colored Progressive Matrices (RCPM) to measure cognitive abilities. Emotional regulation and negative lability were assessed using the Emotion Regulation Questionnaire (ERC). Academic performance was assessed with the Competence Academic Scale (CAS) of the Portuguese version of the Social Skills Rating System-Teacher Form (SSRS-T). Institutionalized children exhibited poorer academic performance than their noninstitutionalized counterparts (effect size, η2 = 0.174). Cognitive ability (β = 0.28) and negative lability (β = -0.28) were significant predictors of academic performance. In addition to institutionalization, cognitive ability, and the challenges of managing negative emotions may contribute to the observed differences in academic performance. Interventions aimed at fostering cognitive and emotional competencies may play a protective role for institutionalized children facing academic and social difficulties.

The Relationship Between Temperament Characteristics and Emotion Regulation Abilities in Institutionalized and Noninstitutionalized Children

This study examined the role of institutionalization and temperament dimensions on emotion regulation and negative lability in school-aged (6-10 years) children. Participants were 46 institutionalized (22 boys; 24 girls) and 48 noninstitutionalized children (23 boys; 25 girls), matched in age and sex. Emotion regulation and negative lability were assessed with the Emotion Regulation Checklist (ERC). The School-Age Temperament Inventory (SATI) was used to measure temperament dimensions. No significant between-group differences emerged in temperament dimensions, emotion regulation and negative lability. After controlling for institutionalization status, results indicated that (a) approach/withdrawal (sociability) and persistence positively predicted emotion regulation, (b) negative reactivity positively predicted negative lability, and (c) persistence negatively predicted negative lability. Institutionalization did not predict emotion regulation or negative lability. The protective role that specific temperament characteristics, such as persistence and approach/withdrawal (sociability), may have for at risk populations (e.g., institutionalized) and typically developing (e.g., noninstitutionalized) children is highlighted.

Rates of depressive and anxiety symptoms in the perinatal period during the COVID-19 pandemic: Comparisons between countries and with pre-pandemic data

BACKGROUND

The COVID-19 pandemic was a significant threat to perinatal mental health. This study examined differences in clinically significant depression, anxiety, and co-morbid symptoms among pregnant and postpartum women across several countries and compared prevalence of perinatal depression and anxiety before and during the pandemic in each participating country.

METHODS

Participants were 3326 pregnant and 3939 postpartum women (up to six months postpartum) living in Brazil, Chile, Cyprus, Greece, Israel, Portugal, Spain, Turkey, and the United Kingdom. An online survey was completed between June 7th and October 31st 2020, and included the Edinburgh Postnatal Depression Scale (EPDS) and the Generalized Anxiety Disorder Screener (GAD-7). The pre-pandemic studies were identified through literature review.

RESULTS

Prevalence of clinically significant depression (EPDS≥13), anxiety (GAD-7 ≥ 10), and co-morbid (EPDS≥13 and GAD-7 ≥ 10) symptoms was 26.7 %, 20 % and 15.2 %, in pregnant women, and 32.7 %, 26.6 % and 20.3 %, in postpartum women, respectively. Significant between-country differences were found in all mental health indicators in both perinatal periods. Higher levels of symptoms were observed during (versus before) the pandemic, especially among postpartum women.

LIMITATIONS

Participants were mostly highly educated and cohabiting with a partner. The online nature of the survey may have limited the participation of women from vulnerable socio-economically backgrounds.

CONCLUSIONS

Our findings expand previous literature on the negative impact of the COVID-19 pandemic on perinatal mental health, by highlighting that this may be influenced by country of residence. Mental health care policies and interventions should consider the unique needs of perinatal women in different parts of the world.

Early predictors of language outcomes in Down syndrome: A mini-review

As children with Down syndrome (DS) typically manifest significant delays in language development, the research has pointed out the predictors of later language skills for this clinical population. The purpose of this study was to systematically explore the evidence for early predictors of language outcomes in infants and toddlers with DS from studies published between 2012 and 2022. After the search, nine studies met the inclusion criteria. The results indicated that maternal educational level, adaptive level of functioning, cognitive function, attention skills, communicative intent of the child, early vocalizations, gestures, baby signs, parents' translation of their children's gestures into words, and vocabulary level are significant predictors of language outcomes in children with DS. These findings provide a timely and warranted summary of published work that contributes to current understanding of the development of language and communication in DS. They are therefore useful to researchers, clinicians, and families.

Processing speed mediates the association between physical activity and executive functioning in elderly adults

Advanced aging is associated with cognitive decline. To decrease the healthcare system and socio-economic burdens as well as to promote better quality of life, is important to uncover the factors that may be related to the delay of cognitive impairments in older adults. This study investigated the relationship between physical activity levels, sedentary behavior and cardiorespiratory fitness with cognitive functioning in healthy older adults. Furthermore, it examined the mediating role of processing speed on the association between physical activity and executive functions and long-term memory. Thirty-two individuals aged between 63 and 77 years (M = 68.16, SD = 3.73) underwent measurements of maximal oxygen uptake (VO₂peak), 1-week of PA accelerometer measurement and a comprehensive cognitive assessment. Significant associations were observed between MVPA and cognitive processing speed. Equally, a significant positive indirect effect of MVPA on executive functioning and long-term memory was mediated by processing speed. Also, MVPA levels differentiated cognitive functioning in older adults – the physical active group outperformed the physical inactive group in processing speed, executive functions, and language abilities. Our results contribute to the literature on the MVPA levels as an important tool to promote healthier cognitive aging.

Paliperidone palmitate-induced enuresis: a case report

Introduction

Schizophrenia is a severe mental illness that requires long-term treatment with antipsychotics and the intramuscular (IM) long-acting injectable (LAI) formulations may enhance treatment adherence. Some antipsychotics have been associated with enuresis, including atypical antipsychotics such as risperidone(6.2%), quetiapine(6.7%), olanzapine (9.6% ) and clozapine (20.7%) [1]. Although oral paliperidone has been related to urinary incontinence, there is only 1 report of urinary incontinence linked to monthly paliperidone palmitate [2]. [1] Harrison-Woolrych, M., Skegg, K., Ashton, J., Herbison, P., Skegg, D.C., 2011. Nocturnal enuresis in patients taking clozapine, risperidone, olanzapine and quetiapine: comparative cohort study. British Journal of Psychiatry 199, 140–144. doi:10.1192/bjp.bp.110.087478 [2] Karslıoǧlu, E.H., Özalp, E., Çayköylü, A., 2016. Paliperidone Palmitate-induced Urinary Incontinence: A Case Report. Clinical Psychopharmacology and Neuroscience 14, 96–100. doi:10.9758/cpn.2016.14.1.96

Objectives

To establish an association between paliperidone palmitate and enuresis.

Methods

Case report and a narrative review of the literature.

Results

The patient was a 25-year-old healthy man when he was diagnosed with schizophrenia. Doctors prescribed paliperidone palmitate (LAI) 200mg monthly and he started to complain of enuresis. He was clearly suffering with this unpleasant and embarrassing adverse effect so the LAI was reduced to 150mg. Enuresis remained, so it was prescribed oxybutynin 20 mg/day and the patient improved.

Conclusions

We reported a case in which enuresis is likely to be associated with high-dose paliperidone LAI (with no clinical evidence of an organic cause). To treat it, the most effective strategy was oxybutynin 20 mg/day. This case is also important to show the impact of this symptom, which is not actively investigated.

Overlap between substance and behavioural addictions: substance abuse in patients with pathological gambling

Introduction

Pathological gambling consists of a persistent and maladaptive pattern of gambling behavior, that often leads to significant adverse psychosocial and financial outcomes. It is currently classified as an “Impulse Disorder” on ICD-10 but the DSM-5 moved this diagnosis from “Impulse-Control Disorders” to “Substance-Related and Addictive Disorders” section^[1]. Behavioral addictions, especially pathological gambling, share many features with substance dependences, namely clinical findings and behavioural patterns, comorbidity with psychiatric disorders, genetic factors and family history, neurobiology, natural history and response to treatment^[2].

Objectives

To study the impact of substance abuse in patients with pathological gambling.

Methods

Literary review, using PubMed database search, regarding substance abuse and pathological gambling.

Results

57,5% of individuals with pathological gambling also present with some form of substance use^[3].There was also a large percentage of patients presenting with nicotine dependence (60,1%) and a fourfold increase in the risk of developing an alcohol use disorder^[3]. Individuals with substance use disorders also show a threefold risk of developing pathological gambling and substance use appears to negatively influence gambling behaviours in this population. Gambling habits in adolescents have been linked to an increased risk of current and lifetime drug use of multiple substances^[4]. Other psychiatric comorbidities were also frequent in this population: 37.9% of patients presented with mood disorders and 37.4% with anxiety disorders^[3].

Conclusions

There is a significant clinical and neurobiological overlap between substance use disorders and pathological gambling. Individuals with pathological gambling have a high prevalence of substance use disorders and an increased lifetime risk of substance use, which negatively influences gambling behavior.

No significant relationships.

A Machine Learning Approach in Autism Spectrum Disorders: From Sensory Processing to Behavior Problems

Atypical sensory processing described in autism spectrum disorders (ASDs) frequently cascade into behavioral alterations: isolation, aggression, indifference, anxious/depressed states, or attention problems. Predictive machine learning models might refine the statistical explorations of the associations between them by finding out how these dimensions are related. This study investigates whether behavior problems can be predicted using sensory processing abilities. Participants were 72 children and adolescents (21 females) diagnosed with ASD, aged between 6 and 14 years (M = 7.83 years; SD = 2.80 years). Parents of the participants were invited to answer the Sensory Profile 2 (SP2) and the Child Behavior Checklist (CBCL) questionnaires. A collection of 26 supervised machine learning regression models of different families was developed to predict the CBCL outcomes using the SP2 scores. The most reliable predictions were for the following outcomes: total problems (using the items in the SP2 touch scale as inputs), anxiety/depression (using avoiding quadrant), social problems (registration), and externalizing scales, revealing interesting relations between CBCL outcomes and SP2 scales. The prediction reliability on the remaining outcomes was “moderate to good” except somatic complaints and rule-breaking, where it was “bad to moderate.” Linear and ridge regression achieved the best prediction for a single outcome and globally, respectively, and gradient boosting machine achieved the best prediction in three outcomes. Results highlight the utility of several machine learning models in studying the predictive value of sensory processing impairments (with an early onset) on specific behavior alterations, providing evidences of relationship between sensory processing impairments and behavior problems in ASD.

Portuguese adolescents' cognitive well-being and basic psychological needs during the COVID-19 outbreak: A longitudinal study

Confinements and social distancing measures during COVID‐19 pandemic were particularly challenging to adolescents, impacting significantly their life and routines. Following a longitudinal design, this study sought to compare adolescents' cognitive well‐being—satisfaction with life, social support, and quality of life—before (T1) and during (T2) the COVID‐19 pandemic. Additionally, it aimed to clarify the predictive value of the three dimensions of the cognitive well‐being to the satisfaction of basic psychological needs of adolescents at school at T2. One thousand ninety‐nine Portuguese adolescents participated, showing generally increased scores in satisfaction with life, social support, and quality of life at T2. Even so, girls revealed lower changes in cognitive well‐being components compared with boys, between T1 and T2. In addition, satisfaction with life and quality of life were predictive of satisfaction of basic psychological needs at T2. This work highlights the relevance of cognitive well‐being as a dispositional dimension in determining the satisfaction of basic psychological needs in adolescence, during a worldwide catastrophic event.

Cortical auditory evoked potentials in 1-month-old infants predict language outcomes at 12 months

The neurophysiological assessment of infants in their first developmental year can provide important information about the functional changes of the brain and supports the study of behavioral and developmental characteristics. Infants' cortical auditory evoked potentials (CAEPs) reflect cortical maturation and appear to predict subsequent language abilities. This study aimed to identify CAEP components to two auditory stimulus intensities in 1-month-old infants and to understand how these are associated with social interactive and self-regulatory behaviors. In addition, it examined whether CAEPs predicted developmental outcomes when infants were assessed at 12 months of age. At 1 month, P2 and N2 components were present for both auditory stimulus intensities, with an increased P2 amplitude being observed for the higher-intensity stimuli. We also observed that an increased P2 amplitude in the lower intensity predicted receptive and expressive language competencies at 12 months. These results are consistent with previous findings indicating an association between auditory processing and developmental outcomes in infants. This study suggests that specific auditory neurophysiological markers are associated with developmental outcomes in the first developmental year.

Maternal sensitivity and infant neural response to touch: an fNIRS study

The mother's attunement to her infant's emotional needs influences her use of touching behaviors during mother-infant interactions. Moreover, maternal touch appears to modulate infants' physiological responses to affective touch. However, little is known about the impact of maternal sensitivity on infants' touch processing at a brain level. This study explored the association between maternal sensitivity when infants (N = 24) were 7 months old and their patterns of cortical activation to touch at 12 months. Brain activation was measured using functional near-infrared spectroscopy. Changes in oxy-hemoglobin (HbO2) and deoxy-hemoglobin (HHb) concentrations were measured in the left somatosensory cortex and right temporal cortex while infants received two types of tactile stimulation-affective and discriminative touch. Results showed that a lower maternal sensitivity was associated with a higher HbO2 response for discriminative touch over the temporal region. Additionally, infants of less sensitive mothers tended to present a higher response in HbO2 for affective touch over the somatosensory region. These findings suggest that less sensitive interactions might result in a lower exposure to maternal touch, which can be further related to infants' neural processing of touch.

The association of social skills and behaviour problems with bullying engagement in Portuguese adolescents: From aggression to victimization behaviors

This study examines sex differences regarding social skills, behavior problems and bullying engagement, and the association of social skills and behavior problems with bullying engagement, in adolescents. Participants were 447 Portuguese adolescents (252 girls and 195 boys) aged between 12 and 19-years-old. Social skills and behavior problems were assessed using the self-report version of Social Skills Improvement System - Rating Scales. Bullying engagement was assessed using the Scale of Interpersonal Behavior at School. Girls scored higher on social skills and reported more internalizing and fewer externalizing problems than boys, whereas boys reported more aggressive verbal behaviors than girls. Adolescents exhibiting fewer social skills and more internalizing and externalizing problems engage more frequently in bullying aggressive behaviors. In addition, adolescents presenting more internalizing and externalizing problems are more often victimized by bullies. Furthermore, boys more frequently engage in bullying aggressive and victimization behaviors, whereas younger adolescents with more social skills tend to engage less frequently in bullying aggressive behaviors.

A Structural Equation Model of Self-Regulation and Healthy Habits as an Individual Protective Tool in the Context of Epidemics-Evidence From COVID-19

Objective: The present study aims to explore the mediation role of self-regulation on health-related behaviors adoption or maintenance, mental health, and well-being during the COVID-19 confinement in a sample of adults in Portugal. Design: One-hundred fifty individuals (118 females, 32 males; Mage = 33.57 year; SD = 12.71) filled an online survey to assess self-regulation, healthy behaviors, mental health, and well-being perception, during the early months of the pandemic (June-August, 2020). Main Outcome Measures: Self-regulation capacity, adoption or maintenance of healthy habits, mental health, including stress management, and the perception of one's well-being were evaluated using a structural equation model (SEM). Results: Self-regulation had direct effects on healthy habits and mental health and indirect effects on well-being and mental health mediated by healthy habits. In specific, a positive direct effect on healthy habits (β = 0.497, p < 0.001) and a negative direct effect on mental health (β = -0.428, p < 0.001); and a positive indirect effect on well-being perception, mediated by healthy behaviors and mental health (β = 0.253, p = 0.003), and a negative indirect effect on mental health, mediated by healthy habits (β = -0.208, p = 0.003). Additionally, healthy habits exerted direct effects on well-being perception and mental health. A positive direct effect on well-being perception (β = 0.254, p = 0.012), and a negative direct effect on mental health (β = -0.418, p < 0.001) were further observed. No direct effect of mental health was observed in well-being perception (β = -0.199, p = 0.068). Finally, a negative correlation was observed between self-regulation and weeks of confinement (r = -0.208, p = 0.021). Conclusion: Self-regulation seems to be a good indicator of adopting a healthy lifestyle and better mental health and well-being in the context of the COVID-19 pandemic. Future preventive actions and interventions to build long-term global preparedness for future health emergencies, such as COVID-19, should explore the importance of self-regulation as an important individual and collective protective factor.

Social Camouflaging in Females with Autism Spectrum Disorder: A Systematic Review

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with increasing prevalence, and a male-to-female ratio of 4:1. Research has been suggesting that discrepancy in prevalence may be due to the fact that females camouflage their symptoms. In this study, we aimed to systematically review evidence on the camouflage effect in females with ASD. Following the PRISMA guidelines, we reviewed empirical research published from January 2009 to September 2019 on PubMed, Web of Science, PsychInfo and Scopus databases. Thirteen empirical articles were included in this review. Overall, evidence supports that camouflaging seems to be an adaptive mechanism for females with ASD, despite the negative implications of these behaviours in their daily life.

Executive Functioning: A Mediator Between Sensory Processing and Behaviour in Autism Spectrum Disorder

Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder characterized by impairments in social interaction, executive functioning, sensory-perceptual abilities and behaviour, such as anxious/depressed states, attention problems, aggression, or somatic complains. However, the dynamic relationship between these dimensions remains to be addressed. Therefore, we explored the link between executive functions, sensory processing and behaviour in 79 children and adolescents with ASD. Results showed significant associations between all dimensions-executive functions, sensory processing and behaviour. Furthermore, using structural equation modelling methods, we observed a mediation effect of executive functioning, specifically the domain pertaining to emotion regulation and control, and in the relationship between sensory processing abnormalities and behavioural problems. We discuss the importance of emotion regulation as a mediator between sensory processing and behavioural impairments and its impact in social competence in ASD.

Social Camouflaging in Females with Autism Spectrum Disorder: A Systematic Review

Autism spectrum disorder (ASD) is a neurodevelopmental disorder with increasing prevalence, and a male-to-female ratio of 4:1. Research has been suggesting that discrepancy in prevalence may be due to the fact that females camouflage their symptoms. In this study, we aimed to systematically review evidence on the camouflage effect in females with ASD. Following the PRISMA guidelines, we reviewed empirical research published from January 2009 to September 2019 on PubMed, Web of Science, PsychInfo and Scopus databases. Thirteen empirical articles were included in this review. Overall, evidence supports that camouflaging seems to be an adaptive mechanism for females with ASD, despite the negative implications of these behaviours in their daily life.

Association of Murine Double Minute 2 polymorphisms with gastric cancer: A systematic review with meta-analysis

Gastric cancer (GC) is the 5th most common type of cancer, with the 3rd highest mortality rate worldwide in both sexes. Murine double minute 2 (MDM2) protein is the major negative regulator of p53, and genetic polymorphisms in this gene have shown to be associated with several types of cancer. In the present study, a literature search was performed using PubMed and Scopus with the following key word combinations 'gastric cancer AND polymorphism AND MDM2'. Studies were carefully revised according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines to identify eligible studies that matched the inclusion criteria. Statistical analysis was performed to assess the association between the different genetic polymorphisms and GC risk, by calculating the odds ratios (OR) and the confidence intervals (CI), with a 5% level of significance. A total of 11 manuscripts studied MDM2 polymorphisms in GC: rs937283 (n=1), rs3730485 (n=1) and rs2279744 (n=9). Both the rs937283 and rs3730485 reports showed an association with GC; however, there was only one study on each of these polymorphisms in the literature. A meta-analysis was performed for the rs2279744 polymorphism, of which studies showed a positive association between the G allele and risk of GC, either in the dominant model (OR=1.46; 95% CI 1.21-1.75; P<0.001) or recessive model (OR 1.65; 95% CI 1.45-1.87; P<0.001). In conclusion, genetic polymorphisms in MDM2 seemed to be associated with an increased risk of GC development, nevertheless, the number of studies were relatively low and the studied populations were primarily Chinese. The present meta-analysis emphasizes the need for additional studies in other populations to corroborate the association of these polymorphisms with GC.

The relationship of emotion regulation and negative lability with socioemotional adjustment in institutionalized and non-institutionalized children

With this study, we aimed to investigate the contribution of emotion regulation and negative lability to socioemotional adjustment in institutionalized and non-institutionalized children. Ninety-two children aged 6 to 10 years (45 placed in residential care after abuse and 47 non-abused, living with their biological families) participated in this study. Emotion Regulation Questionnaire and Strengths and Difficulties Questionnaire were completed by the main caregivers of the institutions and by the elementary teacher, respectively, for the institutionalized and non-institutionalized groups. No differences were observed between institutionalized and non-institutionalized children in emotion regulation, negative lability, and socioemotional adjustment outcomes. Also, no sex and age effects were observed for both groups. Considering the institutionalized children, the length of institutionalization had a significant effect on negative lability, while no effects of the type of maltreatment on emotion regulation and negative lability were observed. Additionally, in institutionalized children, negative lability was negatively associated with peer relationship problems in socioemotional adjustment, whereas in the non-institutionalized children, no significant associations were verified between emotion regulation and negative lability with socioemotional adjustment outcomes. For institutionalized children, emotional lability seems to have a differential impact on specific maladaptive socioemotional outcomes, which emphasizes the importance of analysing these specific risk developmental pathways.

Neural and psychophysiological correlates of social communication development: Evidence from sensory processing, motor, cognitive, language and emotional behavioral milestones across infancy

This article presents a literature review focusing on the neural and psychophysiological correlates associated with social communication development in infancy. Studies presenting evidence on infants' brain activity and developments in infant sensory processing, motor, cognitive, language, and emotional abilities are described in regard to the neuropsychophysiological processes underlying the emergence of these specific behavioral milestones and their associations with social communication development. Studies that consider specific age-related characteristics across the infancy period are presented. Evidence suggests that specific neural and physiological signatures accompany age-related social communication development during the first 18 months of life.

Learning and the Unknown: Surveying Steps toward Open World Recognition

As science attempts to close the gap between man and machine by building systems capable of learning, we must embrace the importance of the unknown. The ability to differentiate between known and unknown can be considered a critical element of any intelligent self-learning system. The ability to reject uncertain inputs has a very long history in machine learning, as does including a background or garbage class to account for inputs that are not of interest. This paper explains why neither of these is genuinely sufficient for handling unknown inputs – uncertain is not unknown, and unknowns need not appear to be uncertain to a learning system. The past decade has seen the formalization and development of many open set algorithms, which provably bound the risk from unknown classes. We summarize the state of the art, core ideas, and results and explain why, despite the efforts to date, the current techniques are genuinely insufficient for handling unknown inputs, especially for deep networks.

Genomic imbalances defining novel intellectual disability associated loci

Background

High resolution genome-wide copy number analysis, routinely used in clinical diagnosis for several years, retrieves new and extremely rare copy number variations (CNVs) that provide novel candidate genes contributing to disease etiology. The aim of this work was to identify novel genetic causes of neurodevelopmental disease, inferred from CNVs detected by array comparative hybridization (aCGH), in a cohort of 325 Portuguese patients with intellectual disability (ID).

Results

We have detected CNVs in 30.1% of the patients, of which 5.2% corresponded to novel likely pathogenic CNVs. For these 11 rare CNVs (which encompass novel ID candidate genes), we identified those most likely to be relevant, and established genotype-phenotype correlations based on detailed clinical assessment. In the case of duplications, we performed expression analysis to assess the impact of the rearrangement. Interestingly, these novel candidate genes belong to known ID-related pathways. Within the 8% of patients with CNVs in known pathogenic loci, the majority had a clinical presentation fitting the phenotype(s) described in the literature, with a few interesting exceptions that are discussed.

Conclusions

Identification of such rare CNVs (some of which reported for the first time in ID patients/families) contributes to our understanding of the etiology of ID and for the ever-improving diagnosis of this group of patients.

Trust in Whom? Dioxin, Organizations, Risk Perception, and Fish Consumption in Michigan's Saginaw Bay Watershed

Trust is generally recognized as important for risk-relevant behavior but research suggests that trust in different organizations may have varying effects. This research advances the literature by testing two hypotheses which postulate that this variability can be explained by risk perception. We collected data from 351 anglers regarding their trust in nine organizations whose efforts are relevant to dioxin contamination in Michigan's Saginaw Bay Watershed, risk perceptions, and self-reports of risky behavior (i.e., consumption of local fish identified as especially likely to contain contaminants). As hypothesized (H1), the negative effect of trust in two agencies-the Michigan Department of Natural Resources (MDNR) and a Michigan Department of Health and Human Services-sponsored River Walker Program (RWP)-on risky behavior was significantly mediated by risk perception but these effects differed from each other such that trust in the MDNR was associated with increased perceptions of risk while trust in the RWP was associated with decreased perceptions of benefit. Also as hypothesized (H2), the positive effect of trust in Dow Chemical Company on risky behavior was significantly mediated by risk perception such that increased trust in Dow was associated with reduced risk perception. The current results lend credence to arguments regarding the importance of specificity in the target of trust and advance this literature by suggesting that differential effects on risk perception help explain this variability. Thus, organizations whose efforts focus on risk communication appear ideally situated to reduce risky behavior through a negative impact on risk perception. Other organizations, however, may run the risk of increasing risky behavior if their efforts result in reduced perceptions of risk.

Contributions of infant vagal regulation at 1 month to subsequent joint attention abilities

Since birth, humans develop an ability to regulate their inner states and behaviors, when facing demanding situations, in order to restore calmness and engage with other persons and the surrounding environment. The present study analyzed whether 1-month infant vagal regulation to auditory stimuli was associated with later joint attention abilities-responding to and initiating joint attention-in interaction with their mothers. Twenty-three infants were assessed and measures of respiratory sinus arrhythmia-RSA (baseline and vagal tone change during auditory stimulation) were used as index of vagal regulation. At 12-months, joint attention behaviors were assessed in a 10-min toy-play mother-infant interaction. Correlational analyses showed that lower baseline RSA and larger increases in vagal tone during auditory stimulation were related to more instances of joint attention behaviors at 12 months, especially responding to joint attention. Results suggest that distinct profiles of autonomic functioning may contribute to joint attention skills.

Fluorescence spectroscopy and parallel factor analysis as a dissolved organic monitoring tool to assess treatment performance in drinking water trains

Fluorescence excitation emission matrix (FEEM) spectroscopy was used to evaluate its applicability as a tool to track dissolved organic matter (DOM) in a drinking water treatment plant (DWTP) that incorporates a conventional line (consisting in ozonation and GAC filtration) and a membrane-based line (consisting in ultrafiltration, reverse osmosis and mineralization) working in parallel. Seven sampling points within the different process stages were characterized monthly during 2014. A global Parallel Factor Analysis (PARAFAC) was used to pull out underlying organic fractions from the fluorescence spectra. Accordingly a five components model was selected to describe the system and the pros and cons of the model were discussed by analysis of the residuals. Among the five fluorescent components, those associated to humic-like matter (C1, C3 and C4) showed a similar season variability in the river water feeding the DWTP (which resembled that of UV₂₅₄ and TOC), whereas the two components associated to protein-like matter (C2 and C5) exhibited a different behavior. The maximum fluorescence intensity values (Fmax) were used to quantify DOM removals across the plant. Compared to the conventional line, water from the UF/RO membrane-based line showed between 6 and 14 times lower fluorescence intensity signal for the humic-like components and between 1 and 3 for the protein-like components as compared to the conventional line. The differences in DOM composition due to seasonal variations and along the treatment trains point out the suitability of using fluorescence measurements over other parameters such as UV₂₅₄ as a monitoring tool to help optimize operation conditions of each treatment stage and improve produced water quality in a DWTP.

Oestrous cycle-dependent expression of Fas and Bcl2 family gene products in normal canine endometrium

During the oestrous cycle canine endometrium undergoes cyclical cellular proliferation, apoptosis and differentiation. To study the regulation of endometrial apoptosis and proliferation events the expression of apoptosis-related genes was analysed by real-time polymerase chain reaction and cellular expression of their proteins was identified through immunohistochemistry. Cellular apoptosis and proliferation events were detected by TdT-mediated dUTP-biotin nick end labeling (TUNEL) and proliferation marker Ki67 immunostaining, respectively. The highest proliferative index was observed in the follicular phase (all endometrial cellular components) and at early dioestrus (basal glands). This was associated with a low apoptotic index and a strong expression of anti- (Bcl2) and pro-apoptotic proteins (Fas, FasL, Bax). Subsequently (Days 11-45 of dioestrus), basal glandular epithelium experienced the highest apoptotic index, coincidental with a decrease of Bcl2 expression and a low ratio of Bcl2/Bax transcription. An increase in the apoptotic index of crypts, stromal and endothelial cells was observed at late dioestrus and the beginning of anoestrus. These results indicate that pro- and anti-apoptotic proteins regulate the balance between cell proliferation and death in the canine endometrium during the oestrous cycle. High Bcl2 expression in both the follicular and early dioestrous phases stimulate glandular proliferation and prevent apoptosis but, in the non-pregnant uterus, a decrease in Bcl2 expression together with an increase in pro-apoptotic proteins induces apoptosis of basal glandular epithelium cells.

Cross-Sectional Validation of a Quality of Life Questionnaire in Spanish for Patients Allergic to Hymenoptera Venom

INTRODUCTION AND OBJECTIVES

The first quality of life questionnaire for Vespula-allergic patients (Vespid Allergy Quality of Life Questionnaire [VQLQ) was developed in 2002. Our objective was to perform the cross-sectional validation of the Spanish version of this questionnaire.

PATIENTS AND METHODS

Using the original English-language version of the VQLQ as a starting point, the Spanish translation and cultural adaptation were performed and the first Spanish version was backtranslated into English and discussed with the authors of the original version. The result was the Spanish Health-related Quality of Life Questionnaire for Hymenoptera Venom-Allergic Patients (HRQLHA). Cross-sectional validation was carried out in a multicenter study using a test-retest design. Patients over the age of 14 diagnosed with systemic allergic reaction to venom from Apis, Vespula, or Polistes species were included. The test-retest reliability, external validity, and internal consistency of the questionnaire were measured.

RESULTS

The sample comprised 116 patients. The mean HRQLHA score was 3.48. Test-retest reliability showed an intraclass correlation coefficient of 0.85. HRQLHA showed a positive correlation (0.5) with an external questionnaire, thus demonstrating its external validity. Analysis of the internal consistency of the HRQLHA yielded a Cronbach α of 0.95, which can be considered to be excellent.

CONCLUSIONS

Statistical analysis revealed the high test-retest reliability, internal consistency, and external validity of the HRQLHA. The HRQLHA is the first validated questionnaire to include patients allergic to Polistes species, which is common in our area. Our findings show that the questionnaire is also valid for these patients.
