What has a year of social isolation due to the COVID-19 pandemic influenced oral parafunctional habits and temporomandibular disorders? A case-control study.

OBJECTIVE: Few studies investigated the influence of oral parafunctional habits during the COVID-19 pandemic. Since some studies have demonstrated that signs and symptoms of temporomandibular disorder (TMD), as well as psychological alterations, increased during the COVID-19 pandemic lockdown, the aim of this study was to investigate whether social isolation is a situation that increases the prevalence of oral parafunctional habits. METHODS: This was an observational case-control study. An online survey with questions about TMD symptoms (Diagnostic Criteria Symptom Questionnaire) and oral parafunctional habits (Oral Behaviours Checklist [OBC]) was administered to Brazilian residents at two different times (2020 and 2021). The participants were divided according to social isolation practices into study groups (GI: 2020, n = 507; GIII: 2021, n = 282) and control groups (GII: 2020, n = 98; GIV: 2021, n = 202). RESULT: In each group, we evaluated the association of the frequency of oral parafunctional habits with the symptoms of TMD, and we observed that individuals with a greater presence of painful TMD present a greater number of oral parafunctional habits. Despite the literature showing that individuals who practiced social isolation developed more oral parafunctional habits, when analysing the association of the OBC questions in Groups GI × GII and GIII × GIV, only 'sustained talking' (p = .0022) and 'hold telephone between your hand and shoulders' (p = .0124) showed a significant difference in GI × GII. Kendall's coefficient of concordance revealed that there was a very strong concordance (GI × GII 0.9515 (p = .0087) and GIII × GIV 0.9655 (p = .0074)) between the ranks of the analysed oral parafunctional habits in all groups. CONCLUSION: We can state that Individuals who practiced social isolation did not present more oral parafunctional habits than individuals who did not.

Oral habits, sociopsychological orthodontic needs, and sociodemographic factors perceived by caregivers impact oral health-related quality of life in children with and without autism?

BACKGROUND: Caregivers play a crucial role in assessing the oral health-related quality of life (OHRQoL) of young individuals with autism spectrum disorder (ASD). AIM: This study assessed the impact of sociodemographic and oral conditions on OHRQoL and family dynamics in young individuals with and without autism, as perceived by guardians. DESIGN: This comparative cross-sectional study included young individuals aged 6 to 14 years and their guardians. Data were collected at a specialized institution and dental schools. Guardians completed the Parental-Caregiver Perceptions Questionnaire (P-CPQ), Family Impact Scale (FIS), and sociodemographic and oral habits questionnaires. The sociopsychological need for orthodontic treatment was assessed using the Index of Orthodontic Treatment Need (IOTN). RESULTS: The sample included 144 youths and caregivers. The ASD group had higher P-CPQ and FIS scores. Factors associated with poorer perceived OHRQoL included higher youth age, lower caregiver education, higher IOTN scores, teeth clenching (RR = 1.20; 95% CI: 1.01-1.41), and lip sucking. Lower parental education (RR = 1.75; 95% CI: 1.10-2.80) and higher IOTN scores from the caregiver's perspective impacted family dynamics. CONCLUSION: Caregivers of young individuals with ASD perceived a lower OHRQoL, and families in this group were more affected by sociodemographic and oral conditions.

Tools developed in Brazil for the promotion and assessment of adequate and healthy eating habits: A scoping review. / Ferramentas para promoção e avaliação da alimentação adequada e saudável desenvolvidas no Brasil: uma revisão de escopo.

The objective of this study was to identify and discuss the tools for the promotion and evaluation of adequate and healthy eating based on the Food Guide for the Brazilian Population. The scoping review was conducted according to the JBI Manual for Evidence Synthesis via the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) checklist and by searching PubMed/MEDLINE, EMBASE, SciELO and LILACS. Sixteen studies on relevant tools, based on the food guide for individuals of all age groups, were thus included: two descriptive studies, two randomized clinical trial protocols, eleven methodological analyses, and one psychometric paper, aimed at either a focal population (n=12) or health professionals (n=4). Six studies addressed tools for promoting adequate and healthy eating, and ten developed tools for evaluating dietary practices or the knowledge and activities of health professionals. This review can therefore assist health professionals in choosing instruments for the implementation and/or dissemination of food guide recommendations, contributing to the promotion of adequate and healthy eating habits.

Dezesseis estudos sobre ferramentas baseadas no guia alimentar para indivíduos de todas as faixas etárias, foram incluídos: dois descritivos, dois de protocolo de estudo clínico randomizado, onze metodológicos e um psicométrico, direcionados à população (n=12) ou à profissionais de saúde (n=4). Seis estudos abordaram ferramentas para promoção da alimentação adequada e saudável e dez desenvolveram ferramentas para avaliação de práticas alimentares ou de conhecimento e atividades de profissionais da saúde. Esta revisão auxiliará os profissionais de saúde na escolha dos instrumentos para o processo de implementação e, ou, divulgação das recomendações do guia alimentar, contribuindo para a promoção da alimentação adequada e saudável.

Vulnerability in adolescents' daily life during the COVID-19 pandemic.

OBJECTIVE: To know the vulnerability in adolescents' daily life during the COVID-19 pandemic. METHOD: Qualitative research carried out with 25 adolescents from a public school in a municipality in southern Brazil in the second half of 2021 through individual semi-structured interviews. Data were submitted to thematic content analysis and interpreted with the vulnerability theoretical framework. RESULTS: These adolescents' daily lives during the COVID-19 pandemic presented difficulties in keeping family members working, changing habits and routines, accessing classes, the internet and increasing intra-family violence. CONCLUSION: Vulnerability in adolescents' daily life during the pandemic can be identified as the absence of interaction in the school context and access to learning resources, reflecting on individual and social vulnerability. Unemployment and possible access to other sources of income have an impact on programmatic vulnerability. Reflection on practices in the context of health and school is suggested, based on the vulnerability identified in adolescents' daily lives during the COVID-19 pandemic.

Habit-, reward- and fear-related motivations in alcohol use disorder: A one-year prospective study.

OBJECTIVE: Cross-sectional studies show that habitual use of alcohol is associated with severity of alcohol dependence reflected across a range of domains and lower number of detoxifications in multiple settings. In this study, we investigated whether alcohol use disorder (AUD) patients with greater habitual use of alcohol at baseline showed worse outcomes after one year of follow-up. METHODS: A sample of inpatients with Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) alcohol use disorder (AUD) was assessed at baseline (n = 50) and after one year (n = 30). The Habit, Reward, and Fear Scale (HRFS) was employed to quantify affective (fear or reward) and non-affective (habitual) drives for alcohol use, the Alcohol Dependence Scale (ADS) was used to assess clinical outcomes, and the Depression, Anxiety and Stress Scale (DASS-21) was used to quantify and control for associated affective symptoms. RESULTS: There was a significant reduction in the three HRFS scores at the follow-up. Regression analyses demonstrated that greater habit- and fear-related drives at baseline predicted greater decreases in the ADS scores at the endpoint. However, after controlling for age, sex and affective symptoms, only reward and fear were associated with reductions in ADS scores at the end of one year. Prescriptions of naltrexone and antidepressants/benzodiazepines did not predict decreases in reward and fear-related motivations. CONCLUSION: Although we were unable to confirm that habitual subscores at baseline predict worse long-term outcomes among inpatients with AUD, we found that a greater fear and reward motives for the use of alcohol predicted a greater magnitude of improvement in the AUD symptoms after one year. We hope that these findings will help develop new approaches toward AUD treatment and inform models of addiction research.

[Mental and nutritional habits at the beginning of the COVID-19 pandemic: impact, perspectives and recommendations]. / Hábitos de salud mental y nutricional a inicios de la pandemia por COVID-19: impacto, perspectivas y recomendaciones.

Besides the severe impact on the mortality rate in the world, the COVID-19 pandemic demonstrated the importance of having an optimal physical and mental health, since subjects with chronic diseases were the most affected. The aim of this review was to describe the consequences of nutritional and mental health during the beginning of the pandemic. In developing countries, such as Mexico, the prevalence of mental illnesses including depression, anxiety, stress, and suicide increased considerably. In addition, it was found an increase rate of sedentary lifestyles due to the confinement established as a preventive measure to avoid COVID-19 infections. Concerning eating habits, it was reported a decrease in fruits and vegetables consumption and an increase in energy-dense foods, as well as alcohol consumption or smoking, as compensatory measures for mental disorders of anxiety and depression. Based on the information we look up on the impact of COVID-19 on human health, we suggest as prevention measures multidisciplinary care strategies aimed at promoting mental health, diet, and physical activity habits in a comprehensive context. Likewise, information it is highlighted the importance of establishing care and monitoring programs for patients with chronic diseases, because this factor was decisive for mortality after COVID-19 infection.

Además de su impacto en la tasa de mortalidad en el mundo, la pandemia por COVID-19 demostró la importancia de un estado de salud física y mental óptimo, ya que los sujetos con enfermedades crónicas fueron los más afectados. El objetivo de esta revisión fue describir las consecuencias de la salud nutricional y mental durante los inicios de la pandemia. En los países en vías de desarrollo, como México, la prevalencia de enfermedades mentales como la depresión, la ansiedad, el estrés y los suicidios aumentaron. Además, incrementaron las cifras de sedentarismo debido al confinamiento. Con relación a los hábitos de alimentación, diversos autores reportaron una disminución en el consumo de frutas, verduras, y un aumento de alimentos densamente energéticos, así como el consumo de alcohol o tabaquismo como medidas compensatorias en relación con los trastornos mentales de ansiedad y depresión. A partir de la información consultada en torno al impacto de la COVID-19 en la salud humana, se sugieren como medidas de prevención estrategias de atención multidisciplinaria encaminadas a promover hábitos de salud mental, alimentación y actividad física en un contexto integral. De igual forma, destaca la importancia de establecer programas de atención y monitoreo de pacientes con enfermedades crónicas, debido a que este factor fue determinante para la mortalidad tras la infección por COVID-19.

Association between Physical Activity Habits with Cardiometabolic Variables, Body Composition, and Physical Performance in Chilean Older Women.

This study aimed to associate physical activity habits with cardiometabolic variables (blood pressure, fasting glucose, HDL cholesterol, and triglycerides), body composition (body fat percentage and fat-free mass), and physical performance (handgrip strength (HGS), timed up-and-go (TUG), and walking speed) in Chilean older women. An analytical cross-sectional study analyzed 179 older women with a mean age of 75.4 years distributed into physically inactive (PI) older women (n = 74) and physically active (PA) older women (n = 105). A logistic regression showed that PI older women presented an increased risk of hyperglycemia (OR = 4.70; p = 0.000), high blood pressure (OR = 3.83; p = 0.000), low HDL cholesterol levels (OR = 2.13; p = 0.03), hypertriglyceridemia (OR = 2.54; p = 0.01), excess body fat percentage (OR = 4.33; p = 0.000), low fat-free mass (OR = 2.22; p = 0.02), low HGS in their dominant hand (OR = 3.37; p = 0.001) and non-dominant hand (OR = 3.60; p = 0.0001), and poor performance in TUG (OR = 5.60; p = 0.000) and walking speed (OR = 5.52; p = 0.000). In conclusion, physical inactivity was associated with increased cardiometabolic risk, excess body fat percentage, lower fat-free mass, and poorer physical performance in Chilean older women. At the same time, PA older women showed a lower cardiometabolic risk, better body composition, and better physical performance than PI older women.

Mediation effect of emotional self-regulation in the relationship between physical activity and subjective well-being in Chilean adolescents.

Adolescents' subjective well-being and physical activity have been found to be correlated in previous studies. However, the underlying mechanisms of this relationship, especially the potential contribution of emotional self-regulation, have received little attention. This study aims to investigate the extent to which emotional self-regulation mediates the association between adolescent physical activity habits and their subjective well-being. The study involved 9585 adolescents who completed a cross-sectional survey. Participants were aged between 10 and 19 years old and attended primary and secondary schools in all 16 regions of Chile. The survey utilized a self-report questionnaire to measure physical activity habits, subjective well-being, and emotional self-regulation. Sociodemographic variables, such as age, gender, and socioeconomic level, were also considered in the analysis. The results showed that physical activity habits, emotional regulation, and subjective well-being were positively correlated. Among these factors, the strongest association was found between subjective well-being and emotional self-regulation. The mediation analysis revealed a partial mediation effect of emotional self-regulation between physical activity habits and subjective well-being. In other words, physical activity habits affect subjective well-being to the extent that these habits affect emotional self-regulation. These findings provide valuable insights into the mechanisms underlying the link between physical activity habits and subjective well-being among adolescents. They also offer useful information for the development of public programs and policies aimed at promoting physical activity habits and subjective well-being in young people.

Burnout and habits harmful to the health of employees in the Argentine federal prison service.

INTRODUCTION: Given that psychosocial risks may be sources of stress at work and also encourage the presence of burnout, members of state security services are likely to present high levels of this syndrome. OBJECTIVES: To describe the prevalence and relationship between burnout and unhealthy habits amongst workers of the Argentine Federal Prison Service (SPF). MATERIAL AND METHOD: An ex post-facto study was carried out with descriptive, cross-sectional, comparative and comparative analyses. We used the Spanish adaptations of the Maslach Burnout Inventory MBI-HSS (Maslach and Jackson, 1986), the Test For Nicotine Dependence (Fagerström, 1978) and the Body Mass Index in 151 prison officers (88 men and 63 women of 22 to 52 years). RESULTS: The prevalence of burnout was 6.62%, while the results for dimensions were: smoking 37.09%, passive smoking 70.20%, overweight 45.03% and obesity 44.37%. The dimensions of burnout showed that differences between groups indicate a higher level of emotional exhaustion in treatment and treatment functions, passive smokers and those who consume less fruit and vegetables on a weekly basis. There was greater depersonalization in subjects that are currently smoking. There was lower personal fulfillment in obese people, passive smokers, current smokers, moderate level smokers, those who consume less fruit and vegetables every week and those with obesity. DISCUSSION: Smoking and high body mass index and links with eating habits are factors that may negatively affect the health and wellbeing of prison officers in terms of personal accomplishment.

[Don Quixote de la Mancha and the description of biphasic sleep in Spanish literature]. / Don Quijote de la Mancha y la descripción del sueño bifásico en la literatura española.

INTRODUCTION: Biphasic or segmented sleep is the habit of sleeping a first and a second sleep separated by a watching. The historian A Ekirch found that this was how people slept in pre-industrial times before the powerful artificial lighting. He is based on texts in different languages, from Antiquity to the 20th century, but the absence of sources in Spanish is striking. AIM: Review the Spanish literature searching references of the biphasic sleep using the keywords 'first sleep' and 'at the first cockcrow'. DEVELOPMENT: In the Second Part of Don Quixote de la Mancha (Chapter 68), Cervantes describes biphasic sleep with remarkable success, correlating the biotypes of Quixote and Sancho with their temperaments and sleeping and eating habits. Strangely, Ekirch cites the chapter, but not biphasic sleep. In this review I reproduce eleven texts in Spanish (13th to 19th centuries), mostly classical works, which refer to it by arranging its phases in a way that coincides with the hours in which the night was divided in the pre-industrial era: 20:00-21:00 to 00:00, first sleep, 00:00 to 03:00, wakefulness; 03:00 to 06:00, second sleep. La Celestina provides significant data too. Recent studies proved that this habit is physiological, and it adapts to the lifestyle that requires it. CONCLUSIONS: References to biphasic sleep in Spanish literature are identified and cited for the first time, confirming Ekirch's hypothesis. In Don Quixote, Cervantes describes it with great breadth and sharpness.

TITLE: Don Quijote de la Mancha y la descripción del sueño bifásico en la literatura española.Introducción. El sueño bifásico o segmentado es el hábito de dormir un primer y un segundo sueño separados por una vigilia. El historiador Ekirch describe que así se dormía en los tiempos preindustriales antes de la potente iluminación artificial. Se basó en textos en diferentes idiomas, desde la Antigüedad hasta el siglo xx, pero llama la atención la ausencia de fuentes en español. Objetivo. Se revisó la literatura española en busca de referencias al sueño bifásico usando como palabras clave 'primer sueño' y 'a los primeros gallos'. Desarrollo. En la segunda parte de Don Quijote de la Mancha (capítulo 68), Cervantes describe el sueño bifásico con notable acierto, correlacionando los biotipos de Quijote y Sancho con sus temperamentos y hábitos de sueño y alimentarios. Curiosamente, Ekirch cita el capítulo, pero no el sueño bifásico. En esta revisión reproduzco 11 textos en español (siglos xiii a xix), mayormente obras clásicas, que lo refieren, disponiendo sus fases en coincidencia con las horas en que se dividía la noche en la era preindustrial: 20:00-21:00 a 00:00, primer sueño; 00:00 a 03:00, vigilia; 03:00 a 06:00, segundo sueño. La Celestina aporta datos significativos. Estudios recientes probaron que este hábito es fisiológico y se adapta al estilo de vida que lo requiere. Conclusiones. Se identifican y citan por primera vez referencias al sueño bifásico en la literatura española, confirmando la hipótesis de Ekirch. El Quijote lo describe con mayor amplitud y agudeza.

Genotoxicity in the oral cells of older people from a Brazilian rural area: a population-based study.

The purpose of this population-based, observational, and cross-sectional study was to evaluate alterations in the oral cells of a population of older people from a Brazilian rural area, using the micronucleus technique to investigate possible associated genotoxic factors. A questionnaire was applied and clinical examination and collection of oral mucosal cells were performed for all older people (≥ 60 years) from a town in southern Brazil. Demographic and socioeconomic variables, deleterious habits (drinking and tobacco use), presence of gastro-oesophageal reflux disease (GERD), and the use of proton pump inhibitors (PPIs) were considered the exposure variables, whereas metanuclear changes (MCs) and the prevalence of cell micronuclei (MN) were considered outcomes. Out of 489 older people, 447 were included in the study, among whom 50.8% were men with a mean age of 70.9 years and 83.9% had a monthly family income greater than US$ 500.00. GERD symptoms were present in 36.2% of the individuals, and 29.1% used PPIs daily, 53.3% consumed alcoholic beverages, and 46.7% used tobacco. The analysis of 1,000 oral mucosal cells per subject showed a MN frequency of 0-2 per individual, and MCs were detected with an average of 15 units per individual (median = 11 per individual). Poisson regression did not show statistical association between the exposure variables and the outcomes (presence of MN and MCs), except for the use of PPIs, which was a protective factor for the prevalence of MN [PR 0.6 (CI 0.3-0,9)]. Age, sex, family income, tobacco use and drinking, and GERD were not associated with the number of MN and MCs in oral mucosal cells of the investigated older people.

Is more prolonged sun exposure associated with healthier life habits and obesity indicators in Portuguese children?

OBJECTIVES: Sun exposure seems to have an indirect effect on the development of obesity through vitamin D synthesis in the skin, the primary source of this vitamin. The present study aimed to investigate associations among sun exposure time, obesity indicators, and lifestyle habits in children. METHODS: A total of 4755 children (3-10 years; 49.86% boys) from the north, center and south-central Portugal were included in the present study. During 2016/2017 children's sun exposure time, screen time, time devoted to the practice of physical activity and active play were collected through standard questionnaires answered by parents. Statistical analyses were conducted to investigate differences among sun exposure time according to the sex, age, obesity indicators and lifestyle habits. RESULTS: Linear regression analysis showed that sun exposure time presented a negative association with Body Mass Index (ß = -0.09, 95% CI: -0.18; -0.003; p = .042), body fat % (ß = -0.31, 95%; CI: -0.54; -0.07; p = .010), computer time (ß = -0.08, 95% CI: -0.12; - 0.05; p < .0001) and a positive association with active play time (ß = 0.22, 95% CI: 0.17; 0.27; p < .0001) and total time of physical activity practice (ß = 10.01, 95% CI: 4.52; 15.20; p < .0001). CONCLUSIONS: The results reinforce the need for future guidance on the ideal sun exposure time, especially in children, who are at risk for vitamin D deficiency. Standardization of criteria for classifying optimal sun exposure time in this age group, considering the parameters that affect vitamin D status, such as age and seasonality, should be considered when planning future guidelines.

Anterior open bite self-correction after cessation of non-nutritive sucking habits: a systematic review.

BACKGROUND: Non-nutritive sucking habits likely may cause occlusal changes such as anterior open bite (AOB) if they persist over extended time. OBJECTIVES: To assess if there is self-correction of AOB after cessation of non-nutritive sucking habits in children older than 4 years old, through a systematic review. SEARCH METHODS: Data sources included PubMed, Scopus, Web of Science and Latin American and Caribbean Health Sciences (LILACS) databases, gray literature as Google Scholar, the database System for Information on Gray Literature in Europe (OpenGrey) and ProQuest Dissertations and Theses Database, also hand searches of the included studies references. SELECTION CRITERIA: Studies assessing occlusal changes in children aged 4-12 years with AOB traits and non-nutritive sucking habits after the discontinuation of the habit were included. DATA COLLECTION AND ANALYSIS: Two authors independently assessed eligibility and extracted data. The risk of bias was assessed using the Newcastle-Ottawa Quality Assessment Scale and the Joanna Briggs Critical Appraisal Checklist for quasi-experimental studies. The confidence in cumulative evidence was assessed using the GRADE criteria. RESULTS: Over 3100 studies, only 5 met the inclusion criteria. There is often self-correction of AOB after discontinuing the non-nutritive sucking habit, even in cases older than 4 years old. The improvement ranged between 50 and 100%. The overall quality of evidence was very low. CONCLUSIONS: AOB self-correction after discontinuing a non-nutritive sucking habit is possible, even after 4 years old, although with very low certainty in the body of evidence. It is not clear after what age the removal from the habit is unlikely to facilitate AOB self-correction. REGISTRATION AND CONFLICT OF INTEREST: International Prospective Register of Systematic Reviews code: CRD42016052171. There was no conflicting interest from the review authors.

Association of breastfeeding duration with the development of non-nutritive habits, and transversal and vertical occlusal alterations in preschool children: A cross-sectional study.

BACKGROUND: Breastfeeding has multiple nutritional, immunological and psychological benefits, as well as a positive influence on the development of the stomatognathic system. OBJECTIVES: The present study attempted to determine the relationship between the duration of breastfeeding and the development of non-nutritive habits, and transversal and vertical occlusal alterations in preschool children. MATERIAL AND METHODS: This cross-sectional study involved 155 preschoolers aged 2-5 years from 3 public schools in Lima, Peru. The sample was divided into 2 groups with regard to the duration of breastfeeding: group A (n = 50) included infants that had been breastfed for up to 6 months; and group B (n = 105) included infants that had been breastfed for 6-12 months. Two trained and calibrated dentists evaluated each group, and clinically determined the presence or absence of transversal or vertical occlusal alterations. Likewise, the children's parents or caregivers were consulted to determine the development of non-nutritive habits. RESULTS: A significant association was found between breastfeeding duration and the development of the oral breathing habit; groups A and B showed a prevalence of 30.0% and 16.2%, respectively (p = 0.048). Likewise, breastfeeding duration affected the appearance of oral breathing (OR (odds ratio) = 0.84; 95% CI (confidence interval): 0.74-0.96; p = 0.011). Furthermore, the use of a bottle for more than 24 months significantly influenced the appearance of oral habits (OR = 3.55; 95% CI: 1.20-10.55; p = 0.022) and open bite (OR = 12.12; 95% CI: 1.16-126.31; p = 0.037). CONCLUSIONS: Breastfeeding duration of 6-12 months was shown to be a protective factor in preventing the appearance of oral breathing. Posterior crossbite (PCB), open bite and deep bite seemed not to be influenced by breastfeeding duration. However, the use of a bottle for more than 24 months significantly influenced the appearance of anterior open bite.

Ultra-processed foods in institutional food services: what are diners eating?

Introduction. Frequent use of ultra-processed foods (UPF) leads to poor health outcomes, and the population must avoid their consumption. Objective. To assess the occurrence of ultra-processed foods (UPFs) in culinary lunch menus from various institutional food services. Materials and methods. Over one month, the five institutional food services analyzed served 1,128 culinary preparations; and a total of 3,863 ingredients were classified according to the extent and purpose of processing using the NOVA classification system. Associations between the occurrence of UPFs and the type, size, and management of food service establishments were analyzed. Five institutional food services in three municipalities (Bauru, Limeira, and Campinas), Brazil. Results. We found 8.4 % up to 12.6 % UPF ingredients used in culinary preparations. The highest frequency of UPFs was associated with private cafeterias (p = 0.002). Most UPFs were part of the recipe or the main ingredient in protein dishes and desserts (p < 0.05) and in university and hospital food services, respectively. UPF use was associated with food service size and type of management (p ≤ 0.003) and was more prevalent in protein dishes (p = 0.003) and large-size institutional food services (28.8 %). Self-managed units (p = 0.03) also use high amounts of UPFs in protein dishes (20.3 %). Conclusions. The presence of UPF rounded 10%; the validity of this value needs further studies. There are no comparative data in the scientific literature regarding the use of these ingredients in institutional food service culinary preparations. Therefore, it is necessary to stimulate reflection to promote healthy food habits and adequate nutrition for diners(AU)

Introducción. El uso frecuente de alimentos ultraprocesados (UPF) conduce a complicaciones de salud, y la población debe evitar su consumo. Objetivo. Evaluar la presencia de alimentos ultraprocesados (UPFs) en los menús de almuerzos de diversos servicios de alimentación institucionales. Materiales y métodos. Durante un mes, los cinco servicios de alimentación institucionales analizados sirvieron 1.128 preparaciones culinarias; y se clasificaron un total de 3.863 ingredientes según el alcance y el propósito del procesamiento, utilizando el sistema de clasificación NOVA. Se analizaron las asociaciones entre la ocurrencia de UPFs y el tipo, tamaño y gestión de los establecimientos de servicio de alimentos. Cinco servicios institucionales de alimentación en tres municipios (Bauru, Limeira y Campinas), Brasil. Resultados. Se encontró entre un 8,4 % hasta un 12,6 % de ingredientes UPF utilizados en las preparaciones culinarias. La mayor frecuencia de UPF se asoció a cafeterías privadas (p = 0,002). La mayoría de los UPFs formaban parte de la receta o eran el ingrediente principal en platos proteicos y postres (p < 0,05) y en los servicios de alimentación universitarios y hospitalarios, respectivamente. El uso de UPFs se asoció con el tamaño del servicio de alimentación y el tipo de gestión (p≤ 0,003) y fue más frecuente en platos proteicos (p = 0,003) y servicios de alimentación institucional de gran tamaño (28,8 %). Las unidades autogestionadas (p = 0,03) también utilizan altas cantidades de UPF en platos proteicos (20,3 %). Conclusiones. La presencia de UPF ronda el 10 %; la validez de este valor necesita más estudios. No existen datos comparativos en la literatura científica sobre el uso de estos ingredientes en las preparaciones culinarias de los servicios de alimentación institucional. Por ello, es necesario estimular la reflexión para promover hábitos alimentarios saludables y una adecuada nutrición de los comensales(AU)

Electrophysiological signature of the interplay between habits and inhibition in response to smoking-related cues in individuals with a smoking habit: An event-related potential study.

The rigid, stimulus-bound nature of drug seeking that characterizes substance use disorder (SUD) has been related to a dysregulation of motivational and early attentional reflexive and inhibitory reflective systems. However, the mechanisms by which these systems are engaged by drug-paired conditioned stimuli (CSs) when they promote the enactment of seeking habits in individuals with a SUD have not been elucidated. The present study aimed behaviourally and electrophysiologically to characterize the nature of the interaction between the reflexive and reflective systems recruited by CSs in individuals with a smoking habit. We measured the behavioural performance and associated event-related potentials (ERPs) of 20 individuals with a smoking habit and 20 controls, who never smoked regularly, in a modified Go/NoGo task during which smoking-related CSs, appetitive and neutral pictures, presented either in first or third-person visual perspective were displayed 250 ms before the Go/NoGo cue. We show that smoking-related cues selectively influence early incentive motivation-related attention bias (N2 after picture onset), motor readiness and behavioural inhibition (Go-P3, NoGo-P3 and Pc) of individuals with a smoking habit only when presented from a first-person visual perspective. These data together identify the neural signature of the aberrant engagement of the reflexive and reflective systems during the recruitment of an incentive habit by CSs presented as if they had been response-produced, that is, as conditioned reinforcers.

Understanding the relationship between orofacial structures and feeding habits of preschoolers: A multivariate analysis.

The understanding of the relationship between orofacial structures and feeding habits in preschoolers is helpful for health professionals and those dedicated to food science. The hypothesis tested was whether this relationship is already present even at a very young age. This cross-sectional study included 91 healthy caries-free children (50 girls/41 boys; 3.4-6.2 years; mean 4.1 years) and a comprehensive evaluation of the stomatognathic system was performed: dietary intake, facial and occlusal morphology, gustatory sensitivity, bite and lip forces, and orofacial myofunctional aspects (mastication, swallowing and breathing functions). Principal component analysis summarized the variables related to the form and function of the orofacial aspects; further, K-means analysis identified two clusters of participants with similar aspects. Cluster 1 ("Low orofacial myofunctional functioning"; n = 51) was characterized by children who showed the worst performance of mastication, swallowing and breathing functions and whose parents reported the consumption of sweets, cookies, chocolate, but not fresh fruits the day before, in addition to the higher bottle-feeding and pacifier use duration. This cluster also showed higher sweet taste threshold. Cluster 2 ("High orofacial myofunctional functioning"; n = 40) showed lower bottle-feeding and pacifier use duration, higher gustatory sensitivity, greater maxillo-mandibular dimensions, and better orofacial function performance. The variables sex and BMI did not associate to clusters profile. The frequencies of open bite and current sucking habit (pacifier) also differed between clusters. The results showed that an association between form and function of the structures that comprise the stomatognathic system and dietary intake is already present in children with primary dentition.
