RESUMO
ABSTRACT Objective: To evaluate the correlation between religiosity and alcohol use among adolescents with orofacial clefts. Methods: Cross-sectional study, developed in a Brazilian public and tertiary hospital, between December 2021 and March 2022. Data collection was hybrid, and three instruments were used: Sociodemographic Questionnaire, Durel Religiosity Scale, and the Alcohol Use Disorders Identification Test. For statistical analysis, the following tests were used: χ2, Fisher's Exact, Mann-Whitney and Spearman's Correlation Coefficient, in addition to analyses of linear correlation strength and bivariate logistic regression. The significance level adopted for all tests was 5% (p≤0.05). Results: 370 adolescents participated, with a mean age of 15.2 years (±1.8). Among them, 23 (5.4%) used alcohol riskly or harmfully, being more frequent among male adolescents (p=0.001), those of mixed race (p=0.046), attending high school (p=0.011), with no religion (p<0.001), or who did not attend religious services (p<0.001). Levels of organizational, non-organizational and intrinsic religiosity were significantly lower among adolescents with risky or harmful alcohol use (p=0.005; p<0.001 and p=0.002, respectively). There was a moderate correlation between risky or harmful alcohol use and non-organizational (r=0.31; p=0.002) and intrinsic (r=0.36; p<0.001) religiosity. Male adolescents (p<0.001; OR=6.58), closest in age to 18 years (p<0.001; OR=1.37), and non-practitioners of religion (p<0.001; OR=6. 48) presented higher odds of risky or harmful alcohol use. Conclusions: Adolescents with higher levels of organizational and intrinsic religiosity used less alcohol, while males, closest in age to 18 years, and non-practitioners of religion presented higher odds of using alcohol riskly or harmfully.
RESUMO Objetivo: Avaliar a correlação entre a religiosidade e o uso de álcool em adolescentes com fissura orofacial. Métodos: Estudo transversal, desenvolvido em um hospital público e terciário brasileiro entre dezembro de 2021 e março de 2022. A coleta de dados foi híbrida, e foram utilizados três instrumentos: Questionário Sociodemográfico, Escala de Religiosidade de Durel e o Alcohol Use Disorders Identification Test. Para a análise estatística foram empregados os testes: qui-quadrado, exato de Fisher, Mann-Whitney e o coeficiente de correlação de Spearman, além das análises de forças de correlação linear e de regressão logística bivariada. O nível de significância adotado para todos os testes foi de 5% (p≤0,05). Resultados: Participaram 370 adolescentes, com média de idade de 15,2 anos (±1,8). Entre eles, 23 (5,4%) usavam o álcool de forma arriscada ou prejudicial. A religiosidade organizacional, não organizacional e a intrínseca foram significativamente menos frequentes entre adolescentes que utilizavam o álcool de forma arriscada ou prejudicial (p=0,005; p<0,001 e p=0,002, respectivamente). Evidenciou-se correlação moderada entre o uso arriscado ou prejudicial do álcool e a religiosidade não organizacional (r=0,31; p=0,002) e a intrínseca (r=0,36; p<0,001). Apresentaram maiores chances de usar o álcool adolescentes do sexo masculino (p<0,001; odds ratio — OR=6,58), com idade mais próxima aos 18 anos (p<0,001; OR=1,37) e que não praticavam a religião (p<0,001; OR=6,48). Conclusões: Adolescentes com maiores níveis de religiosidade organizacional e intrínseca utilizaram menos frequentemente álcool de forma arriscada ou prejudicial, enquanto ser homem, possuir idade mais próxima aos 18 anos e não praticar a religião aumentou a chance de utilizar álcool.
RESUMO
Abstract Objective: Body image is a predictor of physical, psychological, and social health. Therefore, it can be an indicator for detecting health problems, to be used in the context of higher education. The aim of this study was to assess body image satisfaction in higher education students and to determine whether body image dissatisfaction is related to lifestyle behaviours and life satisfaction. Methodology: This study included 166 Portuguese higher education students. Body image was assessed using the Figure Rating Scale. Active choices during everyday life were assessed using the Active Choice Index. The questionnaire also included questions about sleep behaviour and tobacco and alcohol consumption. Satisfaction with Life was assessed using a five-item scale previously adapted for the Portuguese population. Results: There was a predominance of boys dissatisfied with thinness (26.10%), while the majority of girls revealed that they were dissatisfied due to being overweight (55.70%). The results indicate statistically significant differences between boys and girls in terms of body image categories (p<0.001). However, when we analysed the behaviours separately according to gender, there were no differences. Active behaviours, as well as the other health behaviours analysed (hours of sleep per week and alcohol and tobacco consumption) did not differ between the different levels of body image satisfaction (p>0.05). Conclusion: Most of the students are dissatisfied with their body image, with the majority of girls showing dissatisfaction due to being overweight. Lifestyles and life satisfaction do not differ between students who are satisfied and those who are dissatisfied with their body image.
Resumen Objetivo: La imagen corporal es un factor predictivo de la salud psicológica, física y social. Por lo tanto, puede ser un indicador para detectar problemas de salud, para utilizar en el contexto de la educación superior. El objetivo de este estudio fue evaluar la satisfacción con la imagen corporal en estudiantes de enseñanza superior y determinar si la insatisfacción con la imagen corporal está relacionada con los comportamientos de estilo de vida y la satisfacción con la vida. Metodología: En este estudio participaron 166 estudiantes portugueses de enseñanza superior. La imagen corporal se evaluó mediante la escala Figure Rating Scale. Las elecciones activas durante la vida cotidiana se evaluaron mediante el Active Choice Index. El cuestionario también incluía preguntas sobre el comportamiento durante el sueño y el consumo de tabaco y alcohol. La satisfacción con la vida se evaluó mediante una escala de cinco ítems previamente adaptada a la población portuguesa. Resultados: Predominaron los chicos insatisfechos por delgadez (26.10%), mientras que la mayoría de las chicas revelaron estar insatisfechas por sobrepeso (55.70%). Los resultados indican diferencias estadísticamente significativas entre chicos y chicas en cuanto a las categorías de imagen corporal (p<0.001). Sin embargo, al analizar los comportamientos por separado en función del sexo, no se observaron diferencias. Las conductas activas, así como las demás conductas de salud analizadas (horas de sueño semanales y consumo de alcohol y tabaco) no difirieron entre los distintos niveles de satisfacción con la imagen corporal (p>0.05). Conclusiones: La mayoría de los estudiantes están insatisfechos con su imagen corporal, siendo mayoritaria la insatisfacción de las chicas por sobrepeso. Los estilos de vida y la satisfacción vital no difieren entre los alumnos satisfechos y los insatisfechos con su imagen corporal.
RESUMO
Ethanol consumption is among the first five substances with higher risk associated with diseases, disability, and death in the world. Anxiety behavior has been linked to ethanol-addictive conduct. The aim of the present study was to evaluate three strains with differential anxiety behavior: a Wild-type strain; a "Reactive" strain, with an increase in anxiety-related behaviors; and a "Non-Reactive" strain, with lower anxiety-related behaviors, before and after the voluntary consumption of ethanol (10%) protocol. To evaluate anxiety, animals were exposed to the elevated plus-maze 24 h before and after the consumption protocol. On the voluntary consumption of ethanol protocol, the animals were exposed to a water and an ethanol bottle. The weight of the liquid consumed daily for 40 days was registered. Results: all strains increased ethanol vs water consumption: Wild-type: day 8; R: day 10; NR: day 31. Ethanol consumption reduced the number and percentage of open arms entries only on the Wild-type strain. Conclusion: anxiety can predispose to an increase in ethanol consumption and to the maintenance of anxiety-related behaviors.
El consumo de alcohol se encuentra dentro de las primeras cinco sustancias con mayor riesgo asociado con enfermedades, discapacidad y muerte en el mundo. El comportamiento ansioso se ha relacionado con la conducta adictiva al alcohol. El objetivo del presente estudio fue evaluar tres cepas con conductas de ansiedad diferenciales: una cepa normal; una cepa "Reac tiva", con aumento de conductas ansiosas; y una cepa "No-Reactiva", con menor comportamiento ansioso, antes y después del protocolo de consumo voluntario de etanol (10%). Para evaluar la ansiedad, los animales fueron expuestos al laberinto en cruz elevado 24 h antes y después del protocolo de consumo. En el protocolo de consumo voluntario de etanol, los animales fueron expuestos a una botella de agua y a una de etanol. Se registró el peso del líquido consumido durante 40 días. Resultados: todas las cepas aumentaron el consumo de alcohol vs agua: General: día 8; R: día 10; NR: día 31. El consumo de etanol redujo el número y el porcentaje de entradas de brazos abiertos solo en la cepa General. Conclusión: los niveles de ansiedad pueden predisponer a un aumento del consumo de etanol y mantenimiento de comportamientos relacionados con la ansiedad.
RESUMO
Aim: to identify whether demographic variables, the type and length of romantic relationships, and alcohol consumption were risk factors related to attitudes toward intimate partner violence (IPV). Method: 723 adults filled the IPVAS and a demographic survey. Results: women were less likely to accept control; participants with technical education were more likely to tolerate control and abuse; those with secondary education were at higher risk to accept physical violence, while participants aged 26-35 were at lower risk; people who were dating someone were at higher risk to tolerate control, but were at a lower risk to accept physical violence; and those who consume alcohol were more likely to accept abuse. Conclusion: As attitudes toward IPV may predict its future occurrence, research on variables modulating the association between attitudes and IPV execution can strengthen evidence to implement preventive actions, in which shaping attitudes towards IPV are the primary target.
Objetivo: Identificar si las variables sociodemográficas, el tipo, la duración de las relaciones y el consumo de alcohol son factores de riesgo asociados con las actitudes hacia la violencia de pareja (VP). Método: 723 adultos completaron las IPVAS y una encuesta sociodemográfica. Resultados: las mujeres tuvieron menor probabilidad de aceptar el control; los participantes con educación técnica toleraron más control y abuso; las personas con educación secundaria presentaron mayor riesgo de aceptar violencia física, mientras que las personas entre 26 y 35 años mostraron un riesgo menor; quienes tenían una relación tuvieron riesgo mayor para tolerar control, pero menor riesgo para aceptar violencia física; aquellos que reportaron consumir alcohol tuvieron mayor probabilidad de aceptar abuso. Conclusión: Las actitudes hacia la IPV pueden predecir la ejecución de esta conducta en el futuro. Por lo tanto, estudios que indaguen sobre variables que modulen esta asociación incrementarán la evidencia para implementar acciones preventivas, en las que la formación de actitudes hacia la VP sean el objetivo principal de cambio.
RESUMO
OBJECTIVE: To determine if prenatal alcohol exposure (PAE) affected physical and cognitive/behavioral outcomes in apparently typically developing, first-grade children. STUDY DESIGN: Three groups were compared: children with fetal alcohol spectrum disorders (FASD); children with PAE without FASD; and children without PAE. RESULTS: The three groups were significantly different on most physical traits and fewer neurodevelopmental traits. Two-group comparisons of exposed and unexposed, non-FASD groups were statistically different on: height, weight, head circumference (OFC), body mass index (BMI), and palpebral fissure length (PFL). Neurobehavioral outcomes were significant in three-group, but not two-group, comparisons. Few sex differences were observed; however, sex ratios indicated fewer male offspring in first grade among women who consumed 6+ drinks per occasion during pregnancy. For weight, OFC, BMI, age, rural residence, and drinking measures, mothers of exposed children without FASD were intermediaries between, and significantly different from, the other maternal groups. Adjusted for socioeconomic covariates, multivariate analysis of covariance (MANCOVA), three-group comparisons were significantly different for cognitive/behavioral variables (p<.001); however, two-group neurobehavior comparisons for children without FASD were not significant (p>.05). Physical trait MANCOVA comparisons of the non-FASD groups were significant only for weight (p<.004) when tested univariately and through stepdown analysis. Socioeconomic-adjusted trend plots were in the expected direction for nonverbal IQ, problem behaviors, attention, height, weight, OFC, vermilion, PFL, and total dysmorphology score. CONCLUSIONS: Even when meeting developmental norms, children with PAE exhibited trends of poorer growth and cognitive/behavioral traits than children without PAE. These findings support the notion that abstinence during pregnancy is best.
RESUMO
INTRODUCTION AND OBJECTIVES: This research aims to evaluate the efficacy and safety of prophylactic antibiotics in patients with alcohol-related liver disease (ALD). MATERIALS AND METHODS: We systematically searched databases including PubMed, Embase, Cochrane, and Web of Science up to October 2023. Our scope encompassed the influence of prophylactic antibiotics on all-cause mortality, infection, variceal bleeding, hepatic encephalopathy (HE), hepatorenal syndrome (HRS), adverse events (AE), fungal infection, clostridioides difficile infection (CDI), and multidrug-resistant (MDR) bacterial infection. Additionally, total bilirubin, creatinine, platelet counts, and plasma endotoxin levels were also analyzed. RESULTS: After comprehensive selection, 10 studies with 974 participants were included for further analysis. The study demonstrated that prophylactic antibiotic therapy was associated with reductions in infection rates, HE incidence, variceal bleeding, and all-cause mortality. The treatment did not increase the incidence of AE, fungal infection, and CDI, but it did raise the MDR bacteria infection rate. The analysis revealed no significant protective effect of antibiotic prophylaxis on total bilirubin and creatinine levels. Furthermore, the administration of antibiotics led to marginal increases in platelet counts, a minor reduction in endotoxin concentrations, and a subtle enhancement in HRS; however, these changes did not reach statistical significance. CONCLUSIONS: Prophylactic antibiotic therapy was an effective and safe treatment for advanced ALD. To mitigate the risk of MDR bacterial infections, a strategy of selective intestinal decontamination could be advisable. Future investigations should prioritize varied ALD patient populations with extended follow-up periods and assorted antibiotic regimens to solidify the efficacy and safety of ALD treatments.
RESUMO
Growing evidence suggests the tendency to act rashly under positive and negative emotions and affect-related drinking motives connect symptoms of mood disorders with alcohol-related problems. However, studies examining this sequence are scarce in Latin-American samples. The present study evaluated, in Argentinian college students (n = 403; 68.2% women; Mage = 21.03 ± 4.90), a sequential model of symptoms of depression, urgency traits, internal drinking motives, and problematic alcohol use. Path analysis was conducted to examine the direct and indirect associations between symptoms of depression and problematic alcohol use (heavy episodic drinking and alcohol-related negative consequences) via positive and negative urgency traits and internal drinking motives. Findings revealed indirect associations from depressive symptoms to problematic alcohol use via urgency traits and drinking motives (e.g. depression symptomsâpositive [negative] urgencyâenhancement [coping]âdrinking problems). This suggests that students who experience more symptoms of depression may be more likely to react to these experiences of negative affect by engaging in heavy drinking episodes and encounter more alcohol-related problems. This seems to stem from a higher propensity to act rashly during intense emotional experiences and a greater motivation to drink as a means of regulating their mood. Future interventions aimed at preventing or reducing problematic alcohol use (especially among Argentinian young adults) might consider targeting these specific impulsivity traits as well as affect-related drinking motivations.
RESUMO
BACKGROUND: The relationship between alcohol consumption and mental health is complex; drinking may exacerbate anxiety, and in turn, anxiety can lead to excessive drinking. This study explores the relationship between alcohol consumption patterns including wine, beer, and spirits, and anxiety prevalence in selected 13 South American nations. METHODS: This study utilises secondary data spanning 29 years from 1991 to 2019 obtained from the Our World in Data database. It investigates the causal link between the prevalence of anxiety and alcohol consumption in the selected countries using the Granger causality test. RESULTS: Anxiety was found to have a unidirectional effect on wine and beer consumption in Chile, Suriname, Uruguay, and Trinidad and Tobago. Additionally, drinking alcohol consumption appears to impact anxiety levels in Brazil. Argentina demonstrates a bidirectional relationship between anxiety and all three types of alcohol consumption, with similar patterns observed in Brazil (wine and beer), Chile (spirits), and Paraguay (spirits). CONCLUSION: No significant causal relationships for alcohol consumption patterns were found in other nations. The identified Granger causal links follow four distinct directions in this study. These findings provide valuable insights for policymakers, governments, and international investors for informed decision-making regarding regulation and policy tools.

Lignin valorization through heterogeneous photocatalysis is a promising pathway for obtaining value-added products, including chemical building blocks, biofuels, etc. However, several challenges still demand attention and resolution in this field. One of the key parameters in the heterogeneous photocatalytic process is the synthesis of efficient photocatalysts that can accomplish efficient and selective reactions. Selective conversion of lignin can be achieved by using heterojunction photocatalysts which can efficiently separate charge carriers' and promote selective reactions by band structure modulation. This work details a straightforward approach for synthesizing heterojunction photocatalysts based on Bi4Ti3O12 and BiOI involving the hydrothermal and co-precipitation methods. Additionally, the synthesized composites were employed in the selective oxidation of veratryl alcohol, a lignin-derived model compound, to produce high-value-added veratraldehyde. The experimental results showed that the BiOI/Bi4Ti3O12 heterojunction (12.5â mol % BiOI) showed superior activity with a veratraldehyde yield of 5.4 and 27.2 times higher than those of Bi4Ti3O12 and BiOI, respectively. The mechanistic studies revealed that the improved activity and selectivity were due to the enhanced charge carriers' separation and the suppression of reactive oxygen species formation through modulation of band structure. This study allows a green approach to lignin-derived biomass valorization to obtain high-value chemicals.
RESUMO
BACKGROUND: Exposure to domestic violence by triggering repetitive distress and fear can affect neurodevelopmental and mental health in the short and long term. This, in turn, has been linked to an increased risk of substance abuse, such as alcohol abuse in adulthood. OBJECTIVE: The present study aimed to evaluate the association between exposure to violence from the father toward the mother and alcohol abuse in Peruvian women. DESIGN: Cross-sectional study. METHODS: We conducted a secondary analysis of data from the Peruvian Demographic and Family Health Survey (ENDES) of 2019. A total of 19,980 reproductive-aged women (15-49 years old) were surveyed using the Health Questionnaire during 2019. The dependent variable of the study was alcohol abuse, collected through self-report, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) criteria. Intimate partner violence (IPV; violence perpetrated by the father against the mother) was considered as the exposure variable. To assess the association of interest, we only considered observations with complete data and used binary logistic regression models, calculating crude odds ratios and adjusted odds ratios (aOR). For the multivariable model, we adjusted for confounding variables (age, marital status, education level, wealth index, ethnicity, residence, current smoker, depression, and IPV). RESULTS: We analyzed a final sample of 9953 women. The prevalence of interparental violence and alcohol abuse was 41.3% and 1.5%, respectively. We found that interparental violence was associated with higher odds of alcohol abuse (aOR: 2.10; 95% CI: 1.03-4.28) after adjusting for age, marital status, education level, wealth level, ethnicity, area of residence, current smoking, depression, and IPV. CONCLUSION: We identified that women of reproductive age who have been exposed to interparental violence were at higher odds of experiencing alcohol abuse issues.
Understanding the link between witnessing parental violence and alcohol abuse in Peruvian womenWitnessing violence between parents during childhood can leave deep emotional scars. This study explores whether such experiences are related to alcohol abuse among Peruvian women in their adult years. Using data from a national health survey in Peru, the experiences of nearly 20,000 women were analyzed to determine if witnessing violence between their parents during childhood was linked to alcohol problems later in life. Responses from the 2019 Peruvian Demographic and Family Health Survey were examined, focusing on women's reports of childhood exposure to violence between parents and current alcohol abuse, controlling for factors like age, education, and mental health. The study found that women who witnessed their parents engaging in violence were more likely to abuse alcohol as adults. About 41% of the women reported seeing such violence, and of these, a higher proportion struggled with alcohol compared to those who did not witness violence. Understanding the link between childhood experiences and adult behaviors can help develop targeted interventions to prevent alcohol abuse. This research highlights the need for support systems that help women cope with the emotional impacts of childhood trauma, potentially reducing alcohol-related problems in the future.

BACKGROUND: This study aimed to explore the association between the emotional impact of COVID-19 and emotional eating and the risk of alcohol use disorder among Peruvian health science students. METHODS: We conducted a cross-sectional analytical study in which an online questionnaire was administered to 456 health science interns from four cities in Peru. We used the COVID-19 Emotional Impact Profile questionnaire, Mindful Eating Questionnaire, and Alcohol Use Disorders Identification Test. Spearman's correlations were calculated and two multiple linear regression models were developed. RESULTS: 68.4% of the participants were emotional eaters and 8.6% reported low-risk levels of alcohol use disorder. Based on the results of the first model, the overall emotional impact of COVID-19, being overweight or obese, depression and anxiety levels, and living with only one parent were factors associated with emotional eating. The results of the second model showed that the level of depression, living with just one parent, living alone, sex, and number of months as an intern were factors associated with the risk of alcohol use disorder. CONCLUSIONS: To reduce emotional eating and the risk of alcohol use disorder among interns, universities should implement interventions aimed at reducing the emotional impact of COVID-19 and provide nutritional counseling.

BACKGROUND: The prevalence of tobacco and alcohol use among adolescents is alarming, and these substances are among the leading risk factors for current and future health among adolescents. Physical activity has the potential to help prevent substance use among adolescents. The objective of this study was to evaluate the association between physical activity, modes of transportation to or from school, and sitting time with tobacco and alcohol use among 222,495 adolescents. METHODS: This cross-sectional study used data from national surveys conducted in 66 countries, obtained through the Global School-based Student Health Survey, and included adolescents aged 11 to 17 years. Information on physical activity, transportation to or from school, sitting time, and tobacco and alcohol use was collected through self-report questionnaires. Generalized linear models were employed to estimate the associations between these variables. RESULTS: The analysis, adjusted for sex, age, and region, revealed that being physically active was associated with lower odds of smoking (OR: 0.86, 95%CI: 0.83-0.89), alcohol use (OR: 0.74, 95%CI: 0.72-0.76), binge drinking (OR: 0.66, 95%CI: 0.62-0.69), and drunkenness (OR: 0.85, 95%CI: 0.83-0.88) compared to inactivity. Insufficiently active participants also had lower odds of tobacco use (OR: 0.83, 95%CI: 0.80-0.85), alcohol use (OR: 0.77, 95%CI: 0.75-0.79), binge drinking (OR: 0.91, 95%CI: 0.87-0.96), and drunkenness (OR: 0.88, 95%CI: 0.85-0.90) compared to inactive participants. Additionally, active transportation to or from school was associated with lower odds of tobacco use (OR: 0.97, 95%CI: 0.95-0.99), alcohol use (OR: 0.94, 95%CI: 0.92-0.96), and binge drinking (OR: 0.78, 95%CI: 0.75-0.81) compared to those using passive transportation. Participants with acceptable sitting time, however, were more likely to use tobacco (OR: 1.48, 95%CI: 1.45-1.52), use alcohol (OR: 1.68, 95%CI: 1.64-1.72), binge drink (OR: 1.68, 95%CI: 1.62-1.75), and experience drunkenness (OR: 1.66, 95%CI: 1.62-1.69) compared to those with excessive sitting time. CONCLUSION: Being physically active, even at insufficient levels, may have beneficial effects on tobacco and alcohol use in adolescents. Acceptable sedentary time, on the other hand, was positively associated with tobacco and alcohol use.

Zn-air batteries (ZABs) are a promising technology; however, their commercialization is limited by challenges, including those occurring in the electrolyte, and thus, gel polymer electrolytes (GPEs) and hydrogels have emerged as substitutes for traditional aqueous electrolytes. In this work, PVA/PAA membranes were synthesized by the solvent casting method and soaked in 6 M KOH to act as GPEs. The thickness of the membrane was modified (50, 100, and 150 µm), and after determining the best thickness, the membrane was modified with synthesized SiO2 nanospheres and multi-walled carbon nanotubes (CNTs). SEM micrographs revealed that the CNTs displayed lengths of tens of micrometers, having a narrow diameter (95 ± 7 nm). In addition, SEM revealed that the SiO2 nanospheres had homogeneous shapes with sizes of 110 ± 10 nm. Physicochemical experiments revealed that SiO2 incorporation at 5 wt.% increased the water uptake of the PVA/PAA membrane from 465% to 525% and the ionic conductivity to 170 mS cm-1. The further addition of 0.5 wt.% CNTs did not impact the water uptake but it promoted a porous structure, increasing the power density and the stability, showing three-times-higher rechargeability than the ZAB operated with the PVA/PAA GPE.
RESUMO
Garambullo is a plant with little industrial application. However, garambullo contains betalains, photosensitive phytochemical compounds, which through microencapsulation can be used in chitosan-polyvinyl alcohol (PVOH) films for application in tomato coatings. These biopackages were characterized by physical tests, water vapor permeability, puncture tests, extension, color, differential scanning calorimetry (DCS), Fourier transform infrared (FTIR) spectroscopy, and antioxidant and antimicrobial activity analyses. The influence of the biopackages on the tomato coatings was measured using parameters such as minimum weight loss close to 2% at day 9, pH of 4.6, Brix of 5.5, titratable acidity of 1 g acid/100 mL sample, and shelf life of up to 18 days. The biopackages containing betalain microcapsules had a water vapor permeability of 2 × 10-14 g/h·m·Pa and an elongation of 5 ± 0.5%, indicating that the package did not stretch. The deformation at the breaking point for the package without and with microcapsules was 0.569 and 1.620, respectively. With respect to color, adding white microcapsules and betalains can cause the material to darken, resulting in a yellowish color. Furthermore, the phenolic content was greater for the biopackages with betalains, while there was no significant difference in the antioxidant activity since the active compounds were not released. According to the in vitro results, the inhibition of B. cinerea was achieved on the eighth day when the active compounds were released from the microcapsules. The tomato with betalains lost 2% of its weight, and B. cinerea was inhibited, extending its shelf life to 18 days. The proposed biopackages have good properties as biopolymers and inhibit the presence of B. cinerea.
RESUMO
SUMMARY: Underage drinking has become a major public concern having a negative impact on the growth and development of the skeleton. Peak bone mass is attained during adolescence hence the aim of the study was to investigate the effect of acute binge alcohol consumption on trabecular morphometry and tensile strength of the adolescent mandible in the Sprague Dawley (SD) rat. The study comprised of 24 SD rats, aged 7 weeks, placed into either the alcohol-exposed [n=12 (6 males and 6 female)] or pair-fed control group [n=12 (6 male and 6 female)]. The treatment of the groups was as follows; the alcohol exposed group and the pair-fed control were administered a single daily dose of 3 g/kg of 20 % alcohol 3 days a week (alternate days) for 7 days and a caloric equivalent dose of maltose dextrin via oral gavage, respectively. The animals were terminated on day 7 via pentobarbital injection. The mandibles were harvested and scanned using a Nikon XTH 255L 3D-microCT scanner (Nikon Metrology, Leuven, Belgium), and biomechanical tests were done using a Shimadzu universal tensile strength testing machine (China). Following scanning and reconstruction, the trabecular morphometry was assessed using Volume Graphics Studio® software. A 3-point bending test was used to evaluate the tensile strength of the bone. Findings from our study showed changes in some trabecular parameters in the female alcohol-exposed group, while the male groups remained unaffected. No changes in tensile strength were seen when comparing male pair-fed control and alcohol-exposed groups and when comparing female pair-fed control and alcohol-exposed groups. Trabecular and tensile strength differences were observed between the sexes when comparing male pair-fed control and alcohol-exposed groups to female pair-fed control and alcohol-exposed groups. These findings do suggest that acute binge alcohol consumption has detrimental effects on the bone micro-architecture in female alcohol-exposed rats and that differences are seen between the sexes.
El consumo de alcohol entre menores de edad se ha convertido en una importante preocupación pública que tiene un impacto negativo en el crecimiento y desarrollo del esqueleto. La masa ósea máxima se alcanza durante la adolescencia, por lo que el objetivo del estudio fue investigar el efecto del consumo excesivo de alcohol en forma aguda sobre la morfometría trabecular y la resistencia a la tracción de la mandíbula en ratas adolescente Sprague Dawley (SD). El estudio estuvo compuesto por 24 ratas, de 7 semanas de edad, colocadas en el grupo control expuesto al alcohol [n=12 (6 machos y 6 hembras)] y alimentado en parejas [n=12 (6 machos y 6 hembras)]. El tratamiento de los grupos fue el siguiente; al grupo expuesto al alcohol y al control alimentado en parejas se les administró una dosis única diaria de 3 g/kg de alcohol al 20 % 3 días a la semana (días alternos) durante 7 días y una dosis equivalente calórica de maltosa dextrina mediante sonda oral, respectivamente. Los animales fueron sacrificados el día 7 mediante inyección de pentobarbital. Las mandíbulas se recolectaron y se escanearon utilizando un escáner 3D-microCT Nikon XTH 255L (Nikon Metrology, Lovaina, Bélgica), y las pruebas biomecánicas se realizaron utilizando una máquina de prueba de resistencia a la tracción universal Shimadzu (China). Después del escaneo y la reconstrucción, la morfometría trabecular se evaluó utilizando el software Volume Graphics Studio®. Se utilizó una prueba de flexión de 3 puntos para evaluar la resistencia a la tracción del hueso. Los hallazgos de nuestro estudio mostraron cambios en algunos parámetros trabeculares en el grupo de hembras expuestas al alcohol, mientras que los grupos de machos no se vieron afectados. No se observaron cambios en la resistencia a la tracción al comparar los grupos control de machos alimentados en parejas y los grupos expuestos al alcohol y al comparar los grupos control de las hembras alimentadas en parejas y los grupos expuestos al alcohol. Se observaron diferencias trabeculares y de resistencia a la tracción entre los sexos al comparar los grupos control de los machos alimentados en parejas y expuestos al alcohol con los grupos de control de hembras alimentadas en parejas y expuestas al alcohol. Estos hallazgos sugieren que el consumo excesivo de alcohol tiene efectos perjudiciales sobre la microarquitectura ósea en ratas hembras expuestas al alcohol y que se observan diferencias entre los sexos.

OBJECTIVE: This study aimed to quantify the health and economic impacts of alcohol consumption in Brazil for 2019. STUDY DESIGN: Ecological study using secondary data sources. METHODS: We calculated the disease burden using estimates from the Global Burden of Disease study, which incorporated data from health surveys and hospital records. Costs were estimated based on direct expenses recorded in the Hospital and Outpatient Information System of the Unified Health System, with data by sex, age group, cause, and Federative Units. RESULTS: Alcohol consumption was a necessary cause for 30,355 deaths and approximately 1.69 million disability-adjusted life years in Brazil, representing 2.2% and 2.6% of the national totals, respectively. The impact was more pronounced among men, in the Northeast region and within the 40- to 64-year-old age group. The total costs attributed to these outcomes reached approximately Int$43.1 million, with hospital admissions accounting for 94.16% of these expenses. CONCLUSION: In 2019, alcohol consumption had a significant impact on both the health of Brazilians and the expenses of the health system. As a preventable risk factor, alcohol consumption necessitates effective intersectoral strategies to mitigate its burden.

Alcohol is a harmful drug, and reducing its consumption is a significant challenge for users. Furthermore, alcohol dependence is often treatment-resistant, and no completely effective treatment model is available for chemical dependence. Classic psychedelics, such as LSD, psilocybin, and ayahuasca have been used in different clinical and pre-clinical trials, demonstrating promising pharmacotherapeutic effects in the treatment of treatment-resistant psychopathological conditions, such as addiction, especially related to alcohol dependence. In this work, we conducted a narrative review of the emerging research regarding the potential of psychedelics for alcohol use disorder treatment. Psychedelic substances have demonstrated potential for treating drug addiction, especially AUD, mostly by modulating neuroplasticity in the brain. Given that serotonergic psychedelics do not produce physical dependence or withdrawal symptoms with repeated use, they may be considered promising treatment options for managing drug use disorders. However, certain limitations could be found. Although many participants achieve positive results with only one treatment dose in clinical studies, great inter-individual variability exists in the duration of these effects. Therefore, further studies using different doses and experimental protocols should be conducted to enhance evidence about psychedelic substances.

OBJECTIVE: The World Health Organization recommends using health-risk warnings on alcoholic beverages. This study examines the impact of separate or combined warning labels for at-risk groups and the general population on alcohol purchase decisions. METHODS: In 2022, 7758 adults who consumed alcohol or were pregnant/lactating women (54.0â¯% female, mean ageâ¯=â¯40.6â¯years) were presented with an online store's beverage section and randomly assigned to one of six warning labels in a between-subjects experimental design: no-warning, pregnant/lactating, drinking-driving, general cancer risk, combined warnings, and assorted warnings across bottles. The main outcome, the intention to purchase an alcoholic vs. non-alcoholic beverage, was examined with adjusted risk differences using logistic regressions. RESULTS: Participants exposed to the general cancer risk warning decreased their alcoholic choices by 10.4 percentage points (pp.) (95â¯% CI [-0.139, -0.069], pâ¯<â¯0.001, ORâ¯=â¯0.561), while those in the pregnancy/lactation warning condition did it by 3.8â¯pp. (95â¯% CI [-0.071, -0.005], pâ¯=â¯0.025, ORâ¯=â¯0.806). The driving-drinking warning had no significant effect. Participants exposed to the combined warnings label, or the assorted warnings reduced alcohol purchase decisions by 6.1â¯pp. (95â¯% CI [-0.095, -0.028], pâ¯<â¯0.001, ORâ¯=â¯0.708) and 4.3â¯pp. (95â¯% CI [-0.076, -0.010], pâ¯=â¯0.011, ORâ¯=â¯0.782), respectively. Cancer warning outperformed other labels and was effective for subgroups such as pregnant/lactating women, young adults, and low-income individuals. CONCLUSIONS: General cancer risk warnings are more effective at reducing alcohol purchase decisions compared to warning labels for specific groups or labels using multiple warnings. In addition to warning labels, other policies should be considered for addressing well-known alcohol-related risks (e.g., drinking and driving).

OBJECTIVE AND DESIGN: The aim of this study was to investigate the effects of ethanol exposure on epigenetic markers in bone marrow (BM) and their impact on inflammatory response during Aspergillus fumigatus infection. RESULTS: Chronic ethanol exposure decreased H3K27me3 enrichment in the Il6 promoter region while increased H3K4me3 enrichment in Tnf. Chimeric mice were generated by transplanting BM from mice exposed to ethanol or water. Infection of ethanol-chimeric mice culminated in higher clinical scores, although there was no effect on mortality. However, previous chronic exposure to ethanol affects persistently the inflammatory response in lung tissue, demonstrated by increased lung damage, neutrophil accumulation and IL-6, TNF and CXCL2 production in ethanol-chimeric mice, resulting in a decreased neutrophil infiltration into the alveolar space. Neutrophil killing and phagocytosis were also significantly lower. Moreover, BM derived macrophages (BMDM) from ethanol-chimeric mice stimulated with A. fumigatus conidia exhibited higher levels of TNF, CXCL2 and IL-6 release and a higher killing activity. The Il6 promoter of BMDM from ethanol-chimeric mice exhibited a reduction in H3K27me3 enrichment, a finding also observed in BM donors exposed to ethanol. CONCLUSIONS: These evidences demonstrate that prior chronic alcohol exposure of bone-marrow modify immune effector cells functions impairing the inflammatory response during A. fumigatus infection. These findings highlight the persistent impact of chronic ethanol exposure on infectious disease outcomes.

BACKGROUND: Outcomes in alcohol-associated liver disease (ALD) are influenced by several race and ethnic factors, yet its natural history across the continuum of patients in different stages of the disease is unknown. METHODS: We conducted a retrospective cohort study of U.S. adults from 2011 to 2018, using three nationally representative databases to examine potential disparities in relevant outcomes among racial and ethnic groups. Our analysis included logistic and linear regressions, along with competing risk analysis. RESULTS: Black individuals had the highest daily alcohol consumption (12.6 g/day) while Hispanic participants had the largest prevalence of heavy episodic drinking (33.5%). In a multivariable-adjusted model, Hispanic and Asian participants were independently associated with a higher ALD prevalence compared to Non-Hispanic White interviewees (OR: 1.4, 95% CI: 1.1-1.8 and OR: 1.5 95% CI:1.1-2.0, respectively), while Blacks participants had a lower ALD prevalence (OR: .7 95% CI: .6-.9), and a lower risk of mortality during hospitalization due to ALD (OR: .83 95% CI: .73-.94). Finally, a multivariate competing-risk analysis showed that Hispanic ethnicity had a decreased probability of liver transplantation if waitlisted for ALD (SHR: .7, 95% CI: .6-.8) along with female Asian population (HR: .40, 95% CI: .26-.62). CONCLUSIONS: After accounting for key social and biological health determinants, the Hispanic population showed an increased risk of ALD prevalence, even with lower alcohol consumption. Additionally, Hispanic and Asian female patients had reduced access to liver transplantation compared to other enlisted patients.
