Background: Predicting neurological recovery in patients with severe brain injury remains challenging. Continuous EEG monitoring can detect malignant patterns but is resource-intensive, and its role in long-term functional outcome prediction is unclear. This study evaluates the utility of parameterized short-segment EEG, acquired via EEG cap, in predicting neurological recovery. Methods: We analyzed short-segment high-density EEGs from 42 patients in the NET-ICU cohort with acute neurological injury. EEGs were pre-processed into standard clinical formats and parameterized using five visual EEG features associated with outcome prediction. Random Forest Classifier (RFC) models were trained and cross-validated to predict recovery of responsiveness (following 1-2 step commands during or after ICU admission) using: EEG features alone; clinician prediction combined with EEG features. Results: EEG-based prediction outperformed clinician bedside assessment (AUC ROC: 0.80 vs. 0.67) under the RFC model. Combining clinician Glasgow Outcome Scale–Extended (GOSE) scores with EEG features improved overall predictive performance (AUC ROC: 0.91). Conclusions: Standardized EEG features obtained using EEG caps can improve the accuracy of neurological recovery predictions in patients with acute severe brain injury. This suggests that automated extraction of background brain signals has the potential to provide clinically meaningful prognostic information in critical care settings, enhancing accessibility and resource efficiency.
Introduction: Throughout the course of the dementia, patients generally need a guardian to protect their rights due to the severity of their mental disabilities. The laws and procedures for guardianship for people with disabilities have been updated in several countries based on the UN Convention on the Rights of Persons with Disabilities promulgated in 2006.
Objectives: To compare the law and procedures for guardianship for people with mental disabilities of twelve countries from six continents.
Methods: Narrative review searching for civil codes/guardianship procedures, date of promulgation, scope of the guardian authority, preferred guardian, duration of the guardianship.
Results: Most countries predominantly promulgated their laws after the year 2000, being half of them updated after 2006. Most countries have two types of guardianship scopes: one concerning financial affairs and the other concerning personal affairs (such as welfare and medical care). Generally, guardianship concerning financial matters is the first to be established. In addition, most countries maintain the ward’s right to vote. In five out of twelve countries, there is an order of preference for choosing the guardian, being the spouses and adult children the preferred guardians. All these countries have the possibility of temporary guardianship. Three countries have a maximum period for guardianship with the possibility of renewal, while all others have indefinite time for guardianship duration. Only France explicitly grants the right to the ward to make medical decisions within guardianship procedures. Brazil’s Civil Code restricts guardianship to financial matters, whereas the Civil Procedure Code requires judges to define the scope of guardianship’s authority for each of the activities of the civil life. Since both codes hold equal authority, judges typically determine the extent of guardianship on a case- by-case basis.
Conclusions: Half of the nations have updated their laws after the promulgation of the UN Convention on the Rights of Persons with Disabilities.
Dementia is expected to increase worldwide and further Discussion concerning the rights of people with dementia is still needed. Although there is no ideal legal framework, the comparison of procedures from different countries may lead to valuable insights for further Discussions andassessments.
Behavioral disorders have been defined as a “health crisis” of modern times that has a significant impact on the parent-child relationship. In this scenario, the emotional regulation (ER) of each partner plays a central role and serves a protective factor, configuring as an area to intervene. The Connect Parent Group, an attachment-based intervention for parents, has shown evidence of effectiveness. However, its online version (e-Connect) has not yet garnered specific evidence related to emotional and physiological regulation in parents and preadolescents.
Objectives
This study aimed to explore changes in the short and medium term regarding ER abilities - both self-reported and measured through physiological indices - in parents and preadolescents with behavioral disorders, building upon initial findings from an online parenting intervention.
Methods
28 parents (82.1% mothers, 17.9% fathers, M_age = 47.48, SD = 4.73) and their 28 preadolescents with behavioral disorders (M_age = 11.22 years, SD = 2.69, 35.7% girls) were recruited from child neuropsychiatry services in Northern Italy and subsequently took part in the pilot study. They were assessed at three time points: before intervention (T1), one months after the intervention (T2) and at 6-months follow-up (T3). ER were assessed with a multimethod approach: parents and children completed a self-report questionnaire (i.e., Difficulties in Emotion Regulation Scale and How I Feel, respectively) and then they interact during a stress-task in which physiological parameters (i.e., Galvanic Skin Response, GSR; Heart Rate/Beat per Minute, BPM) have been measured.
Results
Regarding self-reported ER, mixed-effects regression models showed an improvement in parent emotion dysregulation between T1 and T3 (p=0.004), a decrease in preadolescents’ negative emotions (p=.012) between T1 and T2 and a lower emotion intensity in preadolescents between the three-time points (p=.003). Regarding physiological ER, the two overall models of GSR and BPM were not significant for both parents and children. Yet GSR correlations within three-time points were positive and significant for children (T1-T2: r=.58; T1-T3: r=.68) but not for parents, while BPM correlations between T1 and T2 were significant for parents (r=.49) but not for children.
Conclusions
The online attachment-based parenting program appears to have contributed to a reduction in emotional dysregulation in parents and preadolescents, which seems to persist to some extent in the medium term. The non-significant results at the physiological level may suggest that changes reported by parents and children through self-report questionnaires do not align with changes in the physiological response to interpersonal stress experienced after an online intervention. Clinical and research implications will be discussed.
Background: Sedation in PICU masks physical exam findings, leading to diagnostic challenges. In adult models, electroencephalography can evaluate the brain’s response to sedation using feedforward connectivity and anteriorization of alpha hubs, proving useful for prognostication. Feasibility of model translation into pediatric population was assessed, with the hypothesis that the same markers of adaptive reconfiguration would correlate with a higher potential for recovering consciousness. Methods: Electroencephalograms from children undergoing sedation were analyzed for strength and direction of functional connectivity using the weighted and directed phase lag index. Target population was refined with an iterative inclusion criteria. We examined relationships between hub location reconfiguration, directed phase lag index, baseline Glasgow Coma Scale, and 3-month post-treatment Glasgow Outcome Scale-Extended. Results: Evaluation of 14 subjects showed promise in children aged 5-18 undergoing sedation with midazolam, dexmedetomidine, and propofol. Further analysis of five subjects revealed a correlation between adaptive reconfiguration during anesthesia and both higher baseline Glasgow Coma Scale and Glasgow Outcome Scale-Extended scores post-treatment. Conclusions: The findings indicate that the functional brain network connectivity model may have diagnostic and prognostic potential regarding children’s consciousness levels. While the initial data is promising, further analysis of six additional cases is pending and deemed essential to thoroughly evaluate the model’s efficacy.
Different fertilization strategies can be adopted to optimize the productive components of an integrated crop–livestock systems. The current research evaluated how the application of P and K to soybean (Glycine max (L.) Merr.) or Urochloa brizantha (Hochst. ex A. Rich.) R. D. Webster cv. BRS Piatã associated with nitrogen or without nitrogen in the pasture phase affects the accumulation and chemical composition of forage and animal productivity. The treatments were distributed in randomized blocks with three replications. Four fertilization strategies were tested: (1) conventional fertilization with P and K in the crop phase (CF–N); (2) conventional fertilization with nitrogen in the pasture phase (CF + N); (3) system fertilization with P and K in the pasture phase (SF–N); (4) system fertilization with nitrogen in the pasture phase (SF + N). System fertilization increased forage accumulation from 15 710 to 20 920 kg DM ha/year compared to conventional without nitrogen. Stocking rate (3.1 vs. 2.8 AU/ha; SEM = 0.12) and gain per area (458 vs. 413 kg BW/ha; SEM = 27.9) were higher in the SF–N than CF–N, although the average daily gain was lower (0.754 vs. 0.792 kg LW/day; SEM = 0.071). N application in the pasture phase, both, conventional and system fertilization resulted in higher crude protein, stocking rate and gain per area. Applying nitrogen and relocate P and K from crop to pasture phase increase animal productivity and improve forage chemical composition in integrated crop–livestock system.
Plant-based diets have emerged as athletic performance enhancers for various types of exercise. Therefore, the present study evaluated the effectiveness of plant-based diets on aerobic and strength/power performances, as well as on BMI of physically active individuals. This systematic review and meta-analysis was conducted and reported according to the guidelines outlined in the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) statement. A systematic search of electronic databases, including PubMed, Web of Science and SPORTDiscus, was performed. On the basis of the search and inclusion criteria, four and six studies evaluating the effects of plant-based diets on aerobic and strength/power performances in humans were, respectively, included in the systematic review and meta-analysis. Plant-based diets had a moderate but positive effect on aerobic performance (0·55; 95 % CI 0·29, 0·81) and no effect on strength/power performance (–0·30; 95 % CI −0·67, 0·07). The altogether analyses of both aerobic and strength/power exercises revealed that athletic performance was unchanged (0·01; 95 % CI −0·21, 0·22) in athletes who adopted plant-based diets. However, a small negative effect on BMI (–0·27; 95 % CI −0·40, –0·15) was induced by these diets. The results indicate that plant-based diets have the potential to exclusively assist aerobic performance. On the other hand, these diets do not jeopardise strength/power performance. Overall, the predicted effects of plant-based diets on physical performance are impactless, even though the BMI of their adherents is reduced.
The ACT Network was funded by NIH to provide investigators from across the Clinical and Translational Science Award (CTSA) Consortium the ability to directly query national federated electronic health record (EHR) data for cohort discovery and feasibility assessment of multi-site studies. NIH refunded the program for expanded research application to become “Evolve to Next-Gen ACT” (ENACT). In parallel, the US Food and Drug Administration has been evaluating the use of real-world data (RWD), including EHR data, as sources of real-world evidence (RWE) for its regulatory decisions involving drug and biological products. Using insights from implementation science, six lessons learned from ACT for developing and sustaining RWD/RWE infrastructures and networks across the CTSA Consortium are presented in order to inform ENACT’s development from the outset. Lessons include intentional institutional relationship management, end-user engagement, beta-testing, and customer-driven adaptation. The ENACT team is also conducting customer discovery interviews with CTSA hub and investigators using Innovation-Corps@NCATS (I-Corps™) methodology for biomedical entrepreneurs to uncover unmet RWD needs. Possible ENACT value proposition hypotheses are presented by stage of research. Developing evidence about methods for sustaining academically derived data infrastructures and support can advance the science of translation and support our nation’s RWD/RWE research capacity.
Many studies linked expression and regulation of emotions as transdiagnostic variables involved in the emergence of psychopathological disorders. However, few studies investigated such processes during middle childhood, a critical period of life defined by significant psychological, physical, and social changes.
Objectives
Explore the relationship between child’s emotion regulation – both emotional subjective experience and physiological reactivity – and child’s psychological difficulties.
Methods
20 children (Mage=10.7, SD=1.25; 65% males) and their mothers were recruited from general population. Emotion regulation was assessed with (1) How I Feel (HIF) and Positive and Negative Affect questionnaires (PANAS) and (2) Heart Rate (i.e., Beats Per Minute, BPM) and Heart Rate Variability (i.e., High Frequency and Low Frequency ratio, LF/HF). Child’s psychological difficulties were measured with the parent report Child Behavioral Checklist 6-18 (CBCL-6/18).
Results
Statistically significant correlations emerged between the HIF-Positive emotions scale and both externalizing (rs = -.51) and internalizing (rs = -.46) difficulties; the HIF-Negative emotions scale and internalizing difficulties (rs = .49); LF/HF and internalizing difficulties (rs = -.58). Finally, a non-significant but moderate effect was found between the HIF-Negative emotions scale and externalizing difficulties (rs = .33).
Conclusions
Although the limited number of participants, data suggest an interesting role played by both child’s emotional experience and physiological reactivity on internalizing and externalizing difficulties as reported by mothers. More specifically, child’s experience of positive emotions is associated with fewer internalizing and externalizing difficulties, while child’s experience of negative emotions illustrates an opposite relationship, implying the relevance of looking at child’s emotional subjective experience in understanding psychological difficulties. Moreover, LF/HF ratio – labeled as the child’s sympathovagal balance – seems like it might be higher in children with less internalizing difficulties. Although doubts about LF/HF interpretation, several studies share this view showing a decrease in autonomic reactivity in internalizing problems, such as depression, in adults. Overall, our preliminary results underline the importance of studying the emergence of psychopathological outcomes in middle childhood connected to both psychological and physiological emotional processes.
The SARS-CoV-2 pandemic has produced an unprecedented clinical situation, causing a direct and indirect impact on the physical and mental health of the population. In Spain, between March 15 and June 21 of 2020, it was decreed a home confinement that caused the interruption of the daily life of millions of people. However, there are few studies that analyze the changes produced in psychiatric care in the Emergency Department (ED).
Objectives
To analyze the changes produced in psychiatric emergencies, subanalysing paediatric population, during the first year of the pandemic (COV1/Y-COV1) compared to the previous year (NOCOV/Y-NOCOV1). To analyze the clinical features of patients attended during the lockdown period of the pandemic (LOCK) and compare it to the period of the pandemic after the lockdown (NOLOCK).
Methods
Through the registry of computerized medical records, patients who attended the psychiatric hospital emergency department between 03/01/2019 and 02/28/2021 were identified. We also identified all attendances from 15/03 to 21/06 in 2019 and in 2020 to obtain variables from the lockdown period.
Results
During period of this study, 2694 psychiatric visits made in the ED (1744 patients - 54.3% women, and 69.5% were between 25 and 64 years-), 1537 in NOCOV and 1157 in COV1. Significant differences were found between COV1 and NOCOV in sociodemographic variables, such as employment status and number of offspring. At a clinical level, in COV1, we observed an increase in attendance due to heteroaggressive behaviors, mania, insomnia and problems due to substance use. An increase in the prescription and/or modification of treatment was observed (59.3% vs 54.3%). During COV1, in terms of discharge follow-up in the month following the ED visit, telematic assistance increased (11.4% vs. 5.3%). During the period of study, 282 ED attendances were performed, 153 in Y-NOCOV and 129 in Y-COV1. At a clinical level, during Y-COV1, a decrease in attendances related to substance use was found significant. The sub-analysis carried out for LOCK and NOLOCK yields similar data to those obtained in the COV1 vs. NOCOV1 comparison. During lockdown, the face-to-face follow-up in the month following the ED was significantly lower (39,5% vs 57,1%) regarding telematic follow-up (24,4% vs 5,8%) In this period, an increase of adolescents without previous mental health follow-up was observed (44% LOCK vs. 22% NOLOCK).
Conclusions
Our work supports the hypothesis that the COVID-19 pandemic caused a change in psychiatric care in the ED. It also shows how lockdown changed the attendance in psychiatric emergencies, and also in the later community care attendance. Changes are detected in emergency care for adolescents during the pandemic compared to the previous year. Strikingly, our study does not reflect a quantitative increase in the demand. It would be of interest to continue collecting data after the time of the present project.
The neurobiology of gambling disorder (GD) is not yet fully understood. Although dysfunctional signalling involved in energy homeostasis has been studied in substance use disorders, it should be examined in detail in GD.
Objectives
To compare different endocrine and neuropsychological factors between individuals with GD and healthy controls (HC), and to explore endocrine interactions with neuropsychological and clinical variables.
Methods
A case-control design was performed in 297 individuals with GD and 41 HC, assessed through a semi-structured clinical interview and a psychometric battery, adding 38 HC in the evaluation of endocrine and anthropometric variables.
Results
Individuals with GD presented higher fasting plasma ghrelin (p<.001) and lower LEAP2 and adiponectin concentrations (p<.001) than HC adjusting for body mass index (BMI). The GD group reported higher cognitive impairment regarding cognitive flexibility and decision-making strategies, a worse psychological state, higher impulsivity levels, and a more dysfunctional personality profile. Despite failing to find significant associations between endocrine factors and either neuropsychological or clinical aspects in GD, some impaired cognitive dimensions and lower LEAP2 concentrations significantly predicted GD presence.
Conclusions
This study suggests distinctive neuropsychological and endocrine dysfunctions may operate in individuals with GD, predicting GD presence. Further exploration of endophenotypic vulnerability pathways in GD appear warranted, especially with respect to etiological and therapeutic potentials.

Attachment, as an interpersonal motivational system, is the relational ground that allows emotions to be regulated through action on the Autonomic Nervous System resulting in better psychological outcomes during middle childhood. Emotion dysregulation and autonomic function are often connected to psychiatric symptoms observed in adolescence (e.g. borderline personality disorder traits) and thus middle childhood becomes a critical age for psychopathological trajectories.
Objectives
Examine the relationship between child’s attachment and both psychological and physiological emotional regulation.
Methods
20 children (Mage = 10.7, SD = 1.25; 65% males) were recruited from general population. Attachment was measured through the Child Attachment Interview (CAI), while emotional regulation was assessed with a multimethod approach, using questionnaires i.e. How I Feel (HIF) and Positive and Negative Affect (PANAS), and physiological measurements i.e. Heart Rate Variability (ratio between High Frequency and Low Frequency, HF/LF, labeled as the child’s sympathovagal balance) and Heart Rate (Beats Per Minute, BPM, as an index of physiological reactivity).
Results
Statistically significant correlations emerged between the HIF-Control scale and the Mother and Father Dismissal CAI scale, the PANAS-Negative Affect scale and the Mother and Father Preoccupied Anger CAI scale. Moreover, there was a non-significant but moderate effect (rs > .30) between HF/LF and the Emotional Openness and the Resolution scales of the CAI, and between BPM and the Emotional Openness scale.
Conclusions
Despite the small sample size, more secure children are able to connect with their emotions and properly use them in solving relational problems. Consequently, they are likely to succeed in understanding and regulating emotions as they manage to find more adaptive strategies their own. On the contrary, the presence of dismissal or anger (insecure attachment) towards parents would appear to lead to higher levels of psycho-physiological dysregulation, a core feature of Borderline Personality Disorder dimensions starting to emerge later in adolescence. Future studies should consider physiological dysregulation as an additional factor linked to psychopathological developmental trajectories.
The COVID-19 pandemic represents an epidemiological and psychological crisis (APA, 2020). In this context, although emerging adults are less likely to get COVID-19, they might have suffered from the national lockdowns over the last year, as they are indeed involved in a crucial development period wherein interpersonal relationships undertake a fundamental function in their psychological well-being. To this end, mentalizing abilities and emotion dysregulation may play a crucial role as possible salutogenic or pathogenic factors on the onset of psychiatric symptoms during the three waves of the COVID-19 pandemic.
Objectives
1) To examine the relationship between emotion dysregulation assessed at the end of the first wave of COVID-19, mentalizing assessed during the second wave, and psychiatric symptoms levels assessed during the third wave. 2) To examine the moderation role of mentalizing within the relation between emotion dysregulation and psychiatric symptoms.
Methods
Participants were 83 non-clinical emerging adults (Mage=22.18, SD=4.36; 57.8% females). Measures applied were Difficulties in Emotion Regulation Scale (DERS) to examine emotion dysregulation, Reflective Functioning Questionnaire to examine mentalizing (RFQ_uncertainty; RFQ_certainty) and Symptom Checklist-90-Revised (SCL-90) to examine psychiatric symptoms (Global Severity Index, GSI).
Results
DERS_total score (r=.31, p=.03) and both RFQ_uncertainty (r=.41, p<.01) and RFQ_certainty (r=-.33, p=.02) are associated with GSI. Secondly, a significant moderation role by RFQ_u emerged within the relation between DERS_total score and GSI (∆R2=.067, β=.001, SE=.00, CI[.000, .002]).
Conclusions
These results suggest that mentalizing and emotion dysregulation may play a pivotal role in the onset of psychiatric symptoms during the COVID-19 pandemic. Clinical implications are discussed.
Difficulties in mentalizing (i.e., the ability to reflect on self and others’ internal mental states, operationalized as reflective functioning [RF]; Fonagy et al., 2012) have been associated with psychological symptoms (Luyten et al., 2020), including somatic symptoms (Bizzi et al., 2019). Therefore, the assessment of its dimensions may be clinically relevant for young patients with somatic symptoms, as with Primary Headache (PH), representing one of the most common somatic complaints in children and adolescents.
Objectives
This study aimed to assess RF with a multi-method approach, exploring its relation with somatic symptoms.
Methods
48 adolescents diagnosed with PH (Mage=14.83, SD=2.81; 67% females) were recruited from an Italian Child Neuropsychiatry Clinic. RF was measured both through the Child and Adolescent Reflective Functioning (CRFS) applied to the Child Attachment Interview transcripts and the self-report Reflective Functioning Questionnaire (RFQ), while the Children’s Somatization Inventory (CSI-24) was used to measure the perceived severity of somatic symptoms.
Results
Different relations with somatic symptoms depended on the method used to evaluate RF: no significant correlations were found with the CRFS subscales (General, Other, Self), while a negative significant correlation was found with the RFQ subscale Certainty about mental states (RFQ_C) (r=-.46, p=.016). All subscales of CRFS were negatively correlated with RFQ_C (p=.05), but not with the other RFQ subscale (Uncertainty about mental states; RFQ_U).
Conclusions
This suggests that two measures may lead to different dimensions of the same construct, thus a multi-method assessment of RF would be advisable in clinical practice.
Primary Headache, including Tension-Type Headache (TTH), represents one of the most common somatic disorders in children and adolescents with a strong impact on quality of life. Several risk factors, as environmental, familiar, and psychological features, including personality traits, are related to the development of Primary Headache. However, studies on specific subgroups of TTH are relatively few in early adolescents.
Objectives
Therefore, this cross-sectional pilot study aims at exploring the role of anxiety and alexithymia in early adolescents with and without TTH.
Methods
A sample of 70 early adolescents (Mage=14.59, SD=1.85; 71% females) consisting of a clinical group (31 with TTH) enrolled in an Italian Child Neuropsychiatry Clinic and a comparison group (38 without TTH) enrolled in schools, matched on gender and age, completed: 1) Multidimensional Anxiety Scale for Children (MASC) to detect the Total levels of Anxiety, also in their factor of Physical Symptoms, Social Anxiety, Harm Avoidance, and Separation Anxiety; 2) the Toronto Alexithymia Scale (TAS-20) to detect the Total levels of Alexithymia, also in their factor of Difficulty to Identifying and to Describing Feelings and Externally Oriented Thinking.
Results
TTH outcome positively correlated with Harm Avoidance (rho=.68, p<.001) and Total Alexithymia (rho=.72, p<.001). In a logistic regression, Harm Avoidance and Total Alexithymia predicted 69% of the variance in TTH outcome (p<.032).
Conclusions
This disorder may be a maladaptive strategy to cope with problems and feeling emotions, then early adolescents could be fostered in the acquisition of more adaptive emotion regulation abilities.
Motivational processes underlie behaviors that enrich the human experience, and impairments in motivation are commonly observed in psychiatric illness. While motivated behavior is often examined with respect to extrinsic reinforcers, not all actions are driven by reactions to external stimuli; some are driven by ‘intrinsic’ motivation. Intrinsically motivated behaviors are computationally similar to extrinsically motivated behaviors, in that they strive to maximize reward value and minimize punishment. However, our understanding of the neurocognitive mechanisms that underlie intrinsically motivated behavior remains limited. Dysfunction in intrinsic motivation represents an important trans-diagnostic facet of psychiatric symptomology, but due to a lack of clear consensus, the contribution of intrinsic motivation to psychopathology remains poorly understood. This review aims to provide an overview of the conceptualization, measurement, and neurobiology of intrinsic motivation, providing a framework for understanding its potential contributions to psychopathology and its treatment. Distinctions between intrinsic and extrinsic motivation are discussed, including divergence in the types of associated rewards or outcomes that drive behavioral action and choice. A useful framework for understanding intrinsic motivation, and thus separating it from extrinsic motivation, is developed and suggestions for optimization of paradigms to measure intrinsic motivation are proposed.
The objective was to evaluate the fermentation profile, in vitro gas production and nutritional quality of pornunça (Manihot spp.) silages containing levels of condensed tannin (CT; 0, 4, 8 and 12% on dry matter (DM) basis), at five opening times (0, 3, 7, 14, 28 and 56 days). A completely randomized design in a 4 × 5 factorial arrangement was adopted, with four replications, totalling 80 experimental silos. The pH and NH3-N analyses were performed at all opening times of the silos. The other analyses were performed only with silages opened at 56 days of storage. There was an interaction effect between CT levels and silo opening times for pH and NH3-N. Tannin levels in pornunça silages after 56 days ensiling increased the pH and DM and reduced crude protein (CP) and neutral detergent fibre (NDF). There was a quadratic effect for NH3-N, acetic acid, butyric acid, gas losses, dry matter recovery (DMR), hemicellulose and acid detergent fibre. Inclusion of 4 and 8% CT in pornunça silage promotes a rapid decline in pH, being within the acceptable limit for adequate fermentation at 3 days of ensiling. Silages with 4% CT establish the pH at 28 days of opening the silos, with reduced NH3-N. Silages with 4% CT present higher concentrations of acetic and butyric acids and greater DMR. Inclusion of CT in pornunça silage after 56 days ensiling increases DM and reduces CP and NDF, directly affecting the in vitro degradability and reducing gas production.
To examine children’s exposure to food and beverage advertising across a year of Colombian television based on whether products exceed Pan-American Health Organization (PAHO)-defined nutrient thresholds.
Design:
Nutritional information was obtained for all foods and beverages advertised and used to categorise each product according to the product category (e.g. beverage, snack food) and nutritional quality based on the PAHO model for identifying products in excess of free sugars, Na or saturated fat or containing non-caloric sweeteners or trans-fat. Television audience ratings data were used to derive the average child audience (unique child viewers) per ad and the number of times ads were seen by children in a single week (weekly impressions) based on product category and nutritional quality.
Setting:
All food and beverage ads on cable and over-the-air TV in Colombia in 2017.
Participants:
N/A.
Results:
Of all instances of TV ads, 89·3 % were of unhealthy products. A larger proportion of male and female children, as well as children from low (88·01 %), mid (89·10 %) and high (89·10 %) socio-economic status, are exposed to advertising of unhealthy products, but no significant difference was found between these proportions.
Conclusion:
The majority of foods and beverages advertised to Colombian children are unhealthy. These findings highlight a need to implement statutory measures to reduce children’s exposure to unhealthy food advertising in Colombia, as obesity and overweight have been increasing among school-age children in Colombia, and exposure to television advertising of unhealthy foods is a known contributor to children’s food intake and obesity.
Background: Hand hygiene (HH) is the most important measure for preventing healthcare-associated infections. The objective is to gain insight into the evolution of the degree of compliance with recommendations (DCR) on HH and its associated factors in the surgical areas of a tertiary-care hospital. Methods: This observational, cross-sectional study, was repeated over time, with direct observation of the DCR on HH during the daily activity of healthcare workers in surgical areas: general surgery, urology, vascular surgery, traumatology, neurosurgery, thoracic surgery, heart surgery, pediatric surgery, otorhinolaryngology, gynecology and obstetrics, ophthalmology. Over 14 years (from 2005 to 2018), 15,946 HH opportunities were registered, together with different additional variables (age, sex, professional position, surgical area ). The 2 test was used to study the association and the crude, and adjusted odds ratios were used to quantify its magnitude. Results: The DCR on HH in surgical areas was 49.7% (95% CI, 48.9%–50.5%), and in the group of nonsurgical areas it was 53.4% (95% CI, 53.1%–54.1%). The area with the highest degree of compliance was urology (56.7%; 95% CI, 53.9%–59.6%), and the area with the lowest degree of compliance was traumatology (43.3%; 95% CI, 40.4%–46.2%). Some associated factors were the indications after an activity has been performed (58.6%; aOR, 2.7; 95% CI, 2.5–2.9) and the availability of pocket-size alcohol-based disinfectant (63.8%; aOR, 2.4; 95% CI, 2.2–2.5). Conclusions: The DCR on HH in surgical areas is lower than in other hospital areas, and there is still some margin for improvement. We have identified some modifiable factors that have an independent association with HH compliance in surgical areas. Focusing on them will increase compliance with HH with the ultimate goal of reducing healthcare-associated infections.
