ABSTRACT
ABSTRACT Objective: The aim of this study was to examine the association between bullying victimization and health risk behaviors in adolescents. Methods: A representative sample of 1020 adolescents participated in the study. The variables such as bullying, health risk behaviors (tobacco, drugs, alcohol, sedentary behavior, smartphone use, level of physical activity, and sleep), and economic status were assessed using self-reported questionnaires. Odds ratios with 95% confidence intervals (95%CI) were obtained using binary logistic regression and ordinal, gross, and adjusted logistic regression (p<0.05). Results: Victims of bullying were more likely to smoke (OR 1.75; 95%CI 1.28-2.40), consume alcohol (OR1.43; 95%CI 1.05-1.94), have worse sleep quality (OR 1.94; 95%CI 1.28-2.91), and more sedentary behavior (OR 1.43; 95%CI 1.08-1.89) than those who were not bullied. However, victims were more likely to have high levels of physical activity than their non-bullied peers (OR 1.66; 95%CI 1.22-2.27). Conclusions: Bullying victimization was associated with an increased predisposition for the adoption of health risk behaviors. Interestingly, victims were also more prone to participate in physical activity.
RESUMO Objetivo: Examinar a associação entre vitimização por bullying e comportamentos de risco à saúde em adolescentes. Métodos: Uma amostra representativa de 1.020 adolescentes participou do estudo. As variáveis bullying, comportamentos de risco à saúde (tabaco, drogas, álcool, comportamento sedentário, uso de smartphone, nível de atividade física, sono) e situação econômica foram avaliadas por meio de questionários autorreportados. Razões de chance com intervalos de confiança de 95% (IC95%) foram obtidas por meio de regressão logística binária e regressão logística ordinal, bruta e ajustada (p<0,05). Resultados: As vítimas de bullying apresentaram maior probabilidade de fumar (OR 1,75; IC95% 1,28-2,40), consumir álcool (OR 1,43; IC95% 1,05-1,94), ter pior qualidade de sono (OR 1,94; IC95% 1,28-2,91) e apresentar mais comportamento sedentário (OR 1,43; IC95% 1,08-1,89) do que aqueles que não sofreram bullying. No entanto, as vítimas eram mais propensas a ter níveis elevados de atividade física do que os seus pares não vítimas de bullying (OR 1,66; IC95% 1,22-2,27). Conclusões: A vitimização por bullying esteve associada ao aumento da predisposição para a adoção de comportamentos de risco à saúde. Curiosamente, as vítimas também eram mais propensas a participar de atividades físicas.
ABSTRACT
Abstract Objective: We aim to assess the quality of life of older individuals living in nursing homes. Methodology: A descriptive cross-sectional study was conducted on institutionalized elderly individuals for over three months. The sample size of the study was 260 and Non-randomized convenience sampling was used. The study excluded participants with cognitive impairment, severe medical conditions, physical limitations, communication barriers, severe pain, recent surgery, acute illness, or psychiatric disorders. Ethical approval was obtained, and participants were given informed consent. The study took place in various nursing homes in Lahore in June and July 2023, for the analysis of data Statistical Package for Social Sciences (SPSS version 22) was used, employing frequency distribution, mean, standard deviation, and correlation. Results: The Pearson Correlation coefficient of 0.459 suggests a significant positive correlation between these variables (p < 0.01). This correlation is evident in both directions: Quality of life (QoL) score to Mini Mental Scale and vice versa. Conclusion: While assessing the QoL in elderly inhabitants of nursing residences, cognitive impairment, and high Body mass index (BMI) appeared to influence the overall QoL.

ABSTRACT
Las actividades que realiza el profesional de la enfermería les producen quebranto en la salud, siendo el estrés el primer factor que va a afectar el ritmo propio, ocasionando irritabilidad y ansiedad. La práctica físico-deportiva tiene un efecto positivo sobre su salud física y mental debido a que produce liberación de endorfinas, lo que conlleva una reducción de la ansiedad, la depresión y el estrés, ya que cualquier tipo de actividad física, ya sea de bajo o alto impacto, libera estas sustancias que actúan directamente sobre el cerebro, produciendo sensación de bienestar y relajación inmediata. Se presenta una investigación con un diseño no experimental, desde el enfoque cuantitativo de tipo descriptivo comparativo de corte transversal. Tiene como objetivo: determinar las relaciones entre actividad física y regulación emocional de un grupo de enfermeras (o) s del Hospital Sur en Chilpancingo, Guerrero, México. Se aplicó la Escala para Evaluación de la Inteligencia Emocional TMMS-24 y el Cuestionario Internacional de Actividad Física (IPAQ). Para determinar la relación entre las variables se empleó la Correlación del Rho de Spearman. Las dimensiones estudiadas son la atención, claridad y reparación emocional por parte de la variable dependiente (Control emocional) y las dimensiones Alta, Media y Baja por la variable independiente (Actividad física). En la comunidad donde se observaron los signos y síntomas de nerviosismo, agitación o tensión asociados a situaciones de ansiedad y estrés, se establecen correlaciones directas entre la intensidad de la actividad física y el control emocional de los sujetos investigados, o sea, a menor intensidad de la actividad física menor control y regulación emocional.
As atividades realizadas pelo profissional de enfermagem causam-lhe problemas de saúde, sendo o estresse o primeiro fator que afetará seu próprio ritmo, causando irritabilidade e ansiedade. A prática físico-esportiva tem um efeito positivo sobre sua saúde física e mental, pois produz uma liberação de endorfinas, o que leva a uma redução da ansiedade, da depressão e do estresse, pois qualquer tipo de atividade física, seja ela de baixo ou alto impacto, libera essas substâncias que atuam diretamente no cérebro, produzindo uma sensação de bem-estar e relaxamento imediato. A pesquisa é apresentada em um desenho não-experimental, a partir de uma abordagem quantitativa, descritiva, comparativa, transversal e de corte transversal. Seu objetivo é determinar a relação entre a atividade física e a regulação emocional em um grupo de enfermeiras do Hospital Sur em Chilpancingo, Guerrero, México. Foram aplicados o Emotional Intelligence Rating Scale TMMS-24 e o International Physical Activity Questionnaire (IPAQ). A Correlação Rho de Spearman foi usada para determinar a relação entre as variáveis. As dimensões estudadas são Atenção, Clareza e Reparação Emocional para a variável dependente (Controle Emocional) e as dimensões Alta, Média e Baixa para a variável independente (Atividade Física). Na comunidade onde foram observados os sinais e sintomas de nervosismo, agitação ou tensão associados a situações de ansiedade e estresse, foram estabelecidas correlações diretas entre a intensidade da atividade física e o controle emocional dos sujeitos investigados, ou seja, quanto menor a intensidade da atividade física, menor o controle e a regulação emocional.
The activities carried out by the nursing professional produce them health problems, with stress being the first factor that will affect one's own rhythm, causing irritability and anxiety. Physical-sports practice has a positive effect on their physical and mental health because it produces the release of endorphins, which leads to a reduction in anxiety, depression and stress because any type of physical activity, whether low or high impact, releases these substances that act directly on the brain, producing a feeling of well-being and immediate relaxation. A research is presented with a non-experimental design, from the quantitative approach of a cross-sectional comparative descriptive type. Its objective is to determine the relationships between physical activity and emotional regulation of a group of nurses from the Sur Hospital in Chilpancingo, Guerrero, Mexico. The TMMS-24 Emotional Intelligence Assessment Scale and the International Physical Activity Questionnaire (IPAQ) were applied. To determine the relationship between the variables, Spearman's Rho Correlation was used. The dimensions studied are attention, clarity and emotional repair by the dependent variable (Emotional Control) and the High, Medium and Low dimensions by the independent variable (Physical Activity). In the community where the signs and symptoms of nervousness, agitation or tension associated with situations of anxiety and stress were observed, direct correlations were established between the intensity of physical activity and the emotional control of the subjects studied, that is, at a lower intensity of physical activity, less control and emotional regulation.

Background:A feasibility study was conducted to investigate the effect of different proprietary extracts on joint discomfort associated with repeated episodes of physical activity.Methods:A single-dose randomized, double-blind, placebo-controlled cross-over study was conducted in three phases with different extract combinations. Seventeen individuals aged 40-60 years with a history of knee joint pain aggravation on physical stress were randomized to receive the investigational product or the placebo in a 1:1 ratio. The primary outcome was the time taken to achieve meaningful pain relief (MPR) from baseline using a pain visual analog scale (VAS) compared to the placebo. The secondary outcomes were the pain intensity difference (PID) and joint discomfort at 1-, 2-, 3-, and 4-hours post-product administration and the time-weighted sum of pain intensity difference (SPID) over 4 hours compared to placebo.Results:Participants in two out of eight investigational product groups achieved MPR successfully. The proprietary combination ZV-E (consisting of Z. officinaleand V. negundo) showed the fastest pain reduction with more than 50% of the participants achieving meaningful relief. The BS-ZP (consisting of B. serrata+ Z. officinale+ P. lanceolata) group also had more than 50% of participants reporting MPR at 4 hours post-IP administration. Subsequently, the SPID was found to be lowest in the participants of above stated groups.Conclusions:The proprietary combination of Z. officinaleand V. negundoextracts, 200 mg could be a promising lead to conduct a further trial to investigate its effect on joint pain.
ABSTRACT
Background: The objectives of our study were to determine the changes in lipid profile (total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)) in juvenile idiopathic arthritis (JIA) and assess its association with epidemiological and clinical profile of JIA patients.Methods: This observational study was performed with 46 patients at presentation followed by 38 cases at 3 months and 18 cases at 6 months of follow up. Their demographic profile and clinical parameters including juvenile disease activity score (JADAS 27) were compared with the biomarkers of lipid profile.Results: The mean (SD) age was 105.85 (20.23) months at first visit with mean (SD) disease duration being 15 (6.4) months. Twenty-six participants had oligoarthritic (56.5%), while the rest had polyarthritis (43.4%). Most of the patients had borderline raised TG and LDL-C (cases with raised TG n=14 (30.4%), 12 (31.5%), 5 (27.7%) at 1st visit, 3 months, and 6 months respectively and LDL-C n=12 (26%), 10 (26.3%), 6 (33.3%) at 1stvisit, 3 months, and 6 months respectively). HDL-C level was low in 36 (78.2%) cases at first visit, 28 cases (73.6%) at 3 months and 12 cases (66.6%) at 6 months respectively. Lipid profile was significantly affected by gender difference, duration of disease and drug therapy (p<0.05). Significant association have been found between JADAS score and TGL level with p value 0.03.Conclusions: Children with JIA definitely suffer from dyslipidemia. Among the biomarkers of lipid profile, low level of HDL-C is one of the most important highlights of our study. Further studies can help to strengthen the findings and formulate necessary interventions at an early stage.
ABSTRACT
Background: Physical activity (PA) is defined as any bodily movement produced by skeletal muscles that requires energy expenditure. It has been proven that regular physical activity helps control and prevent noncommunicable diseases like diabetes, heart disease, stroke, and several types of cancer. This study aimed to describe the levels of physical activity among female undergraduate students in Mandya and to assess their knowledge, attitude and practice regarding junk food habits. Methods: This cross-sectional study was done in Government women’s degree college, Mandya district, South Karnataka between November 2023 to December 2023 among female undergraduate students in the institute. Global physical activity questionnaire (GPAQ) has been used to describe their physical activity levels. Descriptive statistics like frequency, proportion, mean and standard deviation has been used. Results: The study was conducted among 170 students. Based on the MET values it is found that majority of them had moderate level of PA 81 (47.6%), while 39(22.9%) had high levels and 50 (29.4%) had low PA levels. Of 170 participants, 43 (25%) had junk food intake once a week, 46 (27%) had twice a week, 81 (48%) had thrice or more per week. The association between PA level and junk food was found to be statistically significant (p<0.05). Conclusions: The findings of this study help us in understanding the importance of adopting a healthy lifestyle, including a balanced diet and regular physical activity practice.
ABSTRACT
Mucormycosis, also referred to as Zygomycosis, is chiefly caused by filamentous molds belonging to the Mucorales group. It can be acquired through inhaling spores, consuming contaminated food, or through injury to the skin. Currently, the second most prevalent fungal infection disease is mucormycosis. It gained greatest attention following the COVID-19 pandemic. The review mainly focuses on several outlines like its history, epidemiology, pathophysiology, types, diagnosis and treatment of mucormycosis. In treatment of mucormycosis, conventional therapy against mucormycosis and some antifungal agents has been discussed. Several diverse contagious ailments were conventionally cured utilizing a widespread series of medicinal plants. Given that India is at the forefront of the Ayurvedic and Siddha medical systems, traditional herbal medicine from India is highly well-known. Antifungal chemicals derived from plants can be a viable option for developing novel and enhanced alternative formulations in the field of antifungal medicine. The main focus of the review is to explore the potential plants having the antifungal activity used for the treatment of mucormycosis. Some of the plants with antifungal activity have been explained, which includes garlic, tea tree oil, aloe vera, thyme, turmeric, neem, eucalyptus, clove, goldenseal, calendula, lavender, guduchi, and oregano. Animal models for mucormycosis study have been explained in the review.
ABSTRACT
Sree Kiran, Sree Rashmi, Sree Pallavi, and Muktakeshi are the four commonly cultivated varieties of Colocasia esculenta (L.) Schott. The current study aims to perform phytochemical screening and the antioxidant capacity of the leaf extracts of these varieties. Furthermore, LCMS was used to examine the polyphenolic content of Muktakeshi's ethanolic leaf extract. The phytochemical analysis of the cultivars indicated that all extracts contained beneficial phytocompounds like phenols, terpenoids, flavonoids, alkaloids, saponins, and tannins. The ethanolic leaf extract of Muktakeshi was found to have greater levels of total phenol (39.47±0.47 GAE mg/g) and flavonoid (49.672±0.15 QE mg/g) contents. All the leaf extracts exhibited a moderate antioxidant ability, whereas the ethanolic extract of Muktakeshi exhibited comparatively higher antioxidant potential in both DPPH (88.3±0.58%) and nitric oxide (84.6±0.79%) assays with the least IC50 value. The LCMS studies detected eight polyphenolic compounds like quercetin, kaempferol, gallic acid, caffeic acid, luteolin 7-rutinoside, chlorogenic acid, vitexin, and rutin in the ethanolic leaf extract of Muktakeshi. It is a good source of many potentially effective bioactive compounds and helps to prevent human oxidative stress-associated diseases. The present study found considerable variations in the phenol-flavonoid content and antioxidant properties of the Colocasia varieties studied.

RESUMEN Los residuos agrícolas son una fuente de celulosa que puede ser aprovechada para producir enzimas hidrolíticas, como las celulasas, mediante acción microbiana. Estas celulasas son utilizadas en procesos extractivos de biomoléculas, en la producción de biogás, en la industria textil, detergente, alimentaria y del papel. El propósito del estudio es la obtención de celulasas bacterianas utilizando residuos orgánicos, generados en plazas de mercado. Se realizaron dos medios de cultivo (A1 y A2), a partir de ameros de mazorca y cáscaras de leguminosas, ajustando el pH del medio A1 a 7,0 y el de A2 a 5,0. Los medios fueron fermentados por 75 horas, mediante la cepa bacteriana C6M2, aislada de residuos de plazas de mercado, monitoreando la actividad enzimática, la concentración de azúcares reductores y la celulosa residual. La máxima actividad celulolítica se logró a las 56 horas de fermentación en A1 y a las 32 horas, en A2. El extracto enzimático se precipitó, dializó y ultrafiltró, obteniendo una actividad final de 9,07 ± 0,48 U/mL. Los ameros y las cáscaras de leguminosa se pueden aprovechar como sustratos en la producción de celulasas, con posibles aplicaciones en procesos donde requieran bajos grados de pureza.
ABSTRACT Agricultural wastes are a source of cellulose that could be used to produce hydrolytic enzymes such as cellulases by microbial action. Cellulases are used in the extractive process of biomolecules, in biogas production, textile, detergent, food, and paper industry. The study purpose is the obtention of bacterial cellulases using organic wastes generated in marketplaces. Two culture media were done (A1 and A2) with corn cob leaves and legume seed pods adjusting the A1 medium pH at 7.0 and the A2 pH at 5.0. The media were fermented for 75 hours by the bacterial strain C6M2, isolated from marketplace wastes, and the enzyme activity, reducing sugar concentration, and residual cellulose were monitored. The maximum cellulolytic activity was obtained at 56 hours of fermentation in A1 and in A2 it was at 32 hours. The enzyme extract was precipitated, dialyzed and ultra-filtrated obtaining a final activity of 9.07 ± 0.48 U/mL. The corn cob leaves and legume seed pods can be used as substrates in the production of cellulases which might be applied in processes with low requirements of enzyme purity.

OBJETIVO: determinar los niveles de glucemia basal, antes y después del consumo del bebible nutricional en deportistas del Centro de Alto Rendimiento del Gobierno Autónomo Municipal de La Paz, gestión 2019. MATERIAL Y MÉTODOS: en este estudio cuasi experimental de antes-después, se analizaron los cambios en los niveles de glucemia de 20 deportistas tras la realización de un protocolo de ejercicio de 30 minutos, seguido de la ingesta de un bebible nutricional. Posteriormente se tomaron glucemias en tres momentos: en reposo, inmediatamente post-ejercicio y una hora después de la intervención. El propósito del estudio fue explorar la influencia del bebible nutricional en la regulación glucémica y su potencial efecto. RESULTADOS: el análisis de los niveles de glucemia basal revelaron una distribución equilibrada entre hiperglucemia e hipoglucemia en el 50% de los deportistas. Fue así que durante el ejercicio y antes de la ingesta del bebible, se observaron fluctuaciones en los niveles de glucosa, con un 5% persistiendo en hiperglucemia y un 25% en hipoglucemia. Una hora posterior de la actividad física y del consumo del bebible, se registraron una mejora significativa en los niveles de glucosa, con un 4% de los deportistas presentando hipoglucemia y un 80% alcanzando niveles de normoglucemia. CONCLUSIONES: luego al consumo del bebible nutricional y del tiempo de absorción de los nutrientes, la glucemia del 80% de los participantes fue de normoglucemia. En 270mL aportó 218,1 kcal 13,52 g de proteínas 1,56 g de grasa 38g de hidratos de carbono y 0,73 g de fibra cruda, sin embargo, hace falta ampliar la muestra para afirmar este efecto
OBJECTIVE: to determine basal blood glucose levels before and after consumption of a nutritional beverage in athletes from the High-Performance Center of the Autonomous Municipal Government of La Paz during the year 2019. MATERIAL AND METHODS: in this quasi-experimental before-and-after study, changes in blood glucose levels were analyzed in 20 athletes following a 30-minute exercise protocol, followed by the intake of a nutritional beverage. Subsequently, blood glucose levels were measured at three points of time: at rest, immediately post-exercise, and one hour after the intervention. The study aimed to explore the influence of the nutritional beverage on glycemic regulation and its potential effects. RESULTS: analysis of baseline blood glucose levels revealed a balanced distribution between hyperglycemia and hypoglycemia in 50% of the athletes. Besides, during exercise and before beverage intake, fluctuations in glucose levels were observed, with 5% persisting with hyperglycemia and 25% with hypoglycemia. One hour after physical activity and beverage intake, a significant improvement in glucose levels was recorded in 80% achieving normoglycemia, and 4% of athletes presenting hypoglycemia. CONCLUSIONS: after consuming the nutritional beverage and nutrient absorption time, 80% of participants exhibited normoglycemia. The beverage provided 218.1 Kcal, 13.52 g of protein, 1.56 g of fat, 38 g of carbohydrates, and 0.73 g of crude fiber per 270 mL. However, further sample expansion is needed to confirm this effect.

Abstract This article aims to analyse the relationship between physical activity (PA) environment at schools, sex, age, and obesity in children, using a network approach. This is a cross-sectional study, with 1,200 children (8.1±1.0 years old) from eight public schools in the same municipality. Weight and height measurements were assessed to calculate the Body Mass Index (BMI) and classified as healthier weight or overweight. To assess the PA environment at school, a interview with the school´s manager was conducted. The association between the PA environment at school and obesity was tested using a Network Analysis performed on the Jasp software. Positive associations between BMI and Physical Education classes (0.847), physical education teacher (0.349), break duration (0.564), and indoor sports court (0.662) were observed. Negative associations were seen with sex (-0.212) age (-0.387), extracurricular PA (-0.492), and playground (-0.557). Additionally, the centrality indicators highlighted extracurricular PA (1.789) as the variables with the highest betweenness values, and BMI with the highest closeness (2.239) and strength (1.230) values. Extracurricular PA and the presence of playgrounds in school´s environment are associated with healthier weight in low-income children.
Resumo O objetivo deste artigo é analisar a relação entre ambiente de atividade física (AF) nas escolas, sexo, idade e obesidade em crianças, usando uma abordagem de rede. Trata-se de um estudo transversal com 1.200 crianças (8,1±1,0 anos) de oito escolas públicas do mesmo município. Peso e estatura foram avaliadas para cálculo do Índice de Massa Corporal (IMC) e classificadas como peso saudável ou sobrepeso. Para avaliar o ambiente de AF na escola, foi aplicado um questionário por meio de entrevista com o gestor da escola. A associação entre o ambiente de AF na escola e a obesidade foi testada por meio Análise de Redes realizada no software Jasp. Foram observadas associações positivas entre o IMC e as aulas de Educação Física (0,847), professor de educação física (0,349), duração do intervalo (0,564) e quadra poliesportiva (0,662). Associações negativas foram observadas com sexo (-0,212), idade (-0,387), AF extracurricular (-0,492) e playground (-0,557). Adicionalmente, os indicadores de centralidade destacaram a AF extracurricular (1,789) como a variável com o maior valor de intermediação, e o IMC com o maior valor de proximidade (2,239) e força (1,230). A AF extracurricular e a presença de playgrounds no ambiente escolar estão associadas a um peso mais saudável em crianças de baixa renda.
ABSTRACT
Background: Sleep disturbances are common among medical students worldwide and affects their health and academic performance. The objective of this study was to assess the quality of sleep in undergraduate medical students of Delhi. Methods: A cross-sectional study was conducted among 234 undergraduate students from medical college in New Delhi. A pre-designed, pre-tested questionnaire was used to collect socio-demographic and life style details and Pittsburgh Sleep Quality Index (PSQI) was used to study the quality of sleep. Data was analyzed by SPSS software version 25.0 and for qualitative data analysis chi-square test was used. Results: Mean age of study subjects was 21.99±1.74 years and males (67.5%) were more as compared to (32.5%) females. Most of the participants 47.4% were in first and second year, 35.5% were from third and final year and 17.1% were interns. Out of 234 participants, only 44% of study participants has good quality of sleep. Most of study participants (56%) were suffering from poor sleep quality. Batch of MBBS, relationship status, BMI and dietary habits of participants were found to be significant predictors of quality of sleep. Conclusions: This study shows that 56% of study participants were suffering from poor quality of sleep. Professionals and medical students who suffer from poor sleep quality have a higher risk of misjudgements, substance abuse, accidents, burnout, anxiety, and depression. So, there is a need to improve knowledge regarding importance of good sleep quality among medical students.
ABSTRACT
Aims: This work aims to investigate the phytochemical composition and antioxidant potential of the leaves of Macaranga heterophylla.Methodology: For this purpose, phytochemical screening by detection tests and thin layer chromatography (TLC), determination of total phenols content, total flavonoids content and condensed tannins content, and assessment of antioxidant potential by DPPH and reducing power tests were carried out on aqueous crude extracts, ethanolic crude extracts and selective extracts of the leaves of M. heterophylla.Results: The percentage yields obtained with ethanol (70%) (28.90 and 24.70% for the ethanolic decoction and ethanolic macerate respectively) are higher than those obtained with water (24.30 and 21.10% for the aqueous decoction and aqueous macerate respectively). The phytochemical screening highlighted the presence of several phytochemical families such as phenolic compounds (coumarins, flavones, tannins), quinones, sterols and polyterpenes, saponosides, glycosides, cardiotonic glycosides and oligosaccharides. Quantitative analysis of total phenolics, total flavonoids and proanthocyanidols showed that their respective levels in the leaves of M. heterophylla varied depending on the solvent and the extraction technique. Concerning total phenolics, the aqueous decoction and ethanolic macerate gave the best total phenol contents (129.04 � 9.53 and 119.82 � 2.63 mg EAG/g DM respectively); for total flavonoids, the aqueous decoction gave the best content (33.03 � 1.61 mg EQ/g DM), while for condensed tannins, the aqueous macerate gave the best content (0.87 � 0.02 mg ECT/g DM). With regard to DPPH antioxidant activity, the results showed that the ethanolic decoction has more pronounced antioxidant activity than the aqueous decoction, while the aqueous macerate showed better antioxidant activity than the ethanolic macerate. Concerning the reducing power test, the opposite trend was observed.Conclusion: The present study demonstrated that M. heterophylla is a concentrate of secondary metabolites with antioxidant properties, which would explain its use in traditional medicinal practice.
ABSTRACT
Resumen Los trastornos del sueño son frecuentes en niños y afectan al desarrollo neurológico, con importante repercusión cognitiva, emocional y conductual. Existe una alta prevalencia de trastornos del sueño (TS) en los trastornos del neurodesarrollo (TND), como trastorno del espectro autista (TEA) y trastorno por déficit de atención con hiperactividad (TDAH). Los TS en población pediá trica tienen una prevalencia del 6-25%, mientras que en los niños con TND esta cifra asciende al 50-80%. En los TND se observa un incremento de las dificultades para conciliar el sueño, de los despertares nocturnos y de la somnolencia diurna. Así mismo, presentan alteracio nes del ritmo circadiano y trastornos respiratorios del sueño. Como consecuencia se produce una reducción de la alerta para las actividades diarias con incremento de trastornos conductuales, problemas emocionales y dificultades académicas asociadas a disfunciones eje cutivas y de memoria. La evaluación del sueño debe formar parte sistemática en la valoración clínica de los niños con TND, con el fin de realizar un diagnóstico y un tratamiento adecuados a cada caso, permitiendo mejorar la calidad de vida del niño y de su familia.
Abstract Sleep disorders are common in children and affect neurological development with important cognitive, emotional and behavioral repercussions. There is a high prevalence of sleep disorders (SD) in neurodevelop mental disorders (NDD) such as autism spectrum dis order (ASD) and attention-deficit hyperactivity disorder (ADHD). Sleep disorders in pediatric population have a prevalence of 6-25%, while in children with NDD this number rises to 50-80%. In NDDs, higher rates of dif ficulties in falling asleep, nocturnal awakenings and daytime sleepiness are observed. Disturbances in the circadian rhythm as well as respiratory sleep disorders are also observed. Consequently, there is a decrease in alertness for daytime activities with increased be havioral disorders, emotional problems and academic difficulties associated with executive and memory dys functions. Sleep assessment has to be a systemic part in the clinical evaluation of children with NDDs, so as to give a convenient diagnosis and treatment in each case, allowing to improve the quality of life of children and their families.
