Dieta rica em fibra promove efeitos metabólicos, hormonais e de saciedade em mulheres obesas com restrição calórica de curto prazo / High-fiber diet promotes metabolic, hormonal, and satiety effects in obese women on a short-term caloric restriction

ABSTRACT Background: Several mechanisms, including excessive hunger, account for patients' difficulties in maintaining weight loss and dietary changes after caloric restriction. Objective: To evaluate the effect of short-term high-fiber calorie-restricted diet in appetite-regulating hormones, and hunger and satiety sensations in women with obesity. Methds: In a randomized controlled trial study, thirty women with body mass index (BMI) higher than 30 kg/m2, and aged from 20 to 50 years were hospitalized following a calorie-restricted diet (1000 kcal/day) for three days. The experimental group (n=15) received high-fiber diet and the control group (n=15), conventional diet. Body weight, BMI, resting energy expenditure (REE), acylated and total ghrelin, leptin, insulin and glucose, and hunger and satiety sensations were evaluated. Linear regression models with mixed effects (fixed and random effects) helped to assess the variables between the two groups and within the groups. Results: Body weight and BMI decreased in both the experimental and control groups (P<0.001). After the high-fiber diet, postprandial acylated ghrelin (P=0.04), glucose (P<0.001), insulin (P=0.04), and leptin (P=0.03) levels as well as the HOMA-IR index (P=0.01) decreased, whereas satiety improved (P=0.02). Obese women that followed the conventional diet had increased body fat percentage (P=0.04) and lower REE (P=0.02). The two diets did not differ in terms of hunger sensation. Conclusion: A short-term high-fiber diet improves satiety sensations and metabolic parameters while suppressing postprandial acylated ghrelin (60 minutes) and maintaining the resting energy expenditure.

RESUMO Contexto: Vários mecanismos, incluindo a fome excessiva, são responsáveis pelas dificuldades dos pacientes em manter a perda de peso e mudanças na dieta após a restrição calórica. Objetivo: Avaliar o efeito da dieta de curta duração rica em fibras e com restrição calórica nos hormônios reguladores do apetite e nas sensações de fome e saciedade em mulheres com obesidade. Métodos: Em um estudo randomizado controlado, 30 mulheres com índice de massa corporal (IMC) superior a 30 kg/m2 e com idade entre 20 e 50 anos foram hospitalizadas seguindo dieta com restrição calórica (1000 kcal/dia) por 3 dias. O grupo experimental (n=15) recebeu dieta rica em fibras e o grupo controle (n=15), dieta convencional. Foram avaliados peso corporal, IMC, gasto energético de repouso (GER), grelina acilada e total, leptina, insulina e glicose e sensações de fome e saciedade. Modelos de regressão linear com efeitos mistos (efeitos fixos e aleatórios) ajudaram a avaliar as variáveis entre os dois grupos e dentro dos grupos. Resultados: O peso corporal e o IMC diminuíram tanto no grupo experimental quanto no controle (P<0,001). Após a dieta rica em fibras, os níveis de grelina acilada pós-prandial (P=0,04), glicose (P<0,001), insulina (P=0,04) e leptina (P=0,03), bem como o índice HOMA-IR (P=0,01) diminuiu, enquanto a saciedade melhorou (P=0,02). Mulheres obesas que seguiram a dieta convencional apresentaram aumento do percentual de gordura corporal (P=0,04) e menor GER (P=0,02). As duas dietas não diferiram em termos de sensação de fome. Conclusão: Uma dieta rica em fibras de curto prazo melhora as sensações de saciedade e os parâmetros metabólicos, suprimindo a grelina acilada pós-prandial (60 minutos) e mantendo o gasto energético de repouso.

Investigation and analysis of appetite status in patients with lymphoma during chemotherapy / 白血病·淋巴瘤

Objective:To investigate the appetite of patients with lymphoma during chemotherapy and its influencing factors.Methods:A total of 103 patients with lymphoma who underwent chemotherapy were sequentially selected in Fujian Medical University Union Hospital from December 2020 to August 2021. The questionnaire survey was carried out by using general information and Karnofsky score was performed. Appetite score was calculated according to Chinese version of the appetite symptom questionnaire for cancer patients. Multiple linear regression analysis was used to analyze the influencing factors of appetite status of lymphoma patients during chemotherapy, and Pearson correlation analysis was used to explore the relationship between Karnofsky score and appetite score of patients.Results:For patients with lymphoma during chemotherapy, Karnofsky score was (75±18) scores and the appetite score was (25.0±5.0) scores. Univariate analysis showed that age, body mass index (BMI), nausea and vomiting, oral mucosa rupture, gum infection, fever, throat infection were influencing factors of appetite score of patients (all P < 0.05). Multivariate analysis showed that patients ' age ( B = -1.118, β = -0.187, P = 0.016), BMI ( B = -2.047, β = -0.271, P = 0.001), nausea and vomiting ( B = -4.352, β = -0.411, P < 0.001) were the independent influencing factors of appetite score. Correlation analysis showed that the Karnofsky score was positively correlated with appetite score ( r = 0.361, P < 0.05). Conclusions:Special attention should be paid to the appetite of elder lymphoma patients with lower BMI during chemotherapy, and nausea and vomiting should be paid more attention; targeted measures of increasing the patients' appetite could improve their nutritional level and prognosis.

The levels of BMI, TG and TC in the observation group were significantly lower than those in the control group at 5 and 10 months after intervention, and the differences were statistically significant ( P <0.05).@*Conclusion@#Experiential health education helps to promote awareness of diabete related knowledge, enhance self management behavior and good diet control habits, and is effective for blood glucose control.

Determinants of disordered eating behaviors: Body mass index, emotional eating, dietary restriction, and motives for eating palatable foods / Determinantes de comportamentos alimentares desordenados: índice de massa corporal, alimentação emocional, restrição alimentar e motivos para comer alimentos palatáveis

ABSTRACT Objective: The study aimed to investigate the relationships between body mass index, reasons for consuming palatable foods, emotional eating, cognitive dietary restraint, and disordered eating behaviors in young adults. Methods: This study was conducted with 800 young adults, in Ankara, Türkiye. A questionnaire consisting of questions about socio-demographic characteristics, health status, and instruments including Eating Attitudes Test-26, Emotional Appetite Questionnaire, Palatable Eating Motives Scale, and The Three-Factor Eating Questionnaire were applied through face-to-face interviews. Results: According to the Eating Attitudes Test-26, 17.2% of males and 27.7% of females were at risk for disordered eating behaviors (χ2=9.750, p=0.002). The mean scores of the Three-Factor Eating Questionnaire-emotional eating, cognitive restraint subscales, and the positive and negative scores of the Emotional Appetite Questionnaire were higher in males than in females (p<0.05). The mean scores of the Palatable Eating Motives Scale-coping and reward enhancement motives were higher in females, while the mean score for the conformity motives was significantly higher in males. Body mass index, Three-Factor Eating Questionnaire-cognitive restraint subscale, Emotional Appetite Questionnaire-negative, and PEMS-conformity motives were found for predictors for Eating Attitudes Test-26 (all p<0.05). Conclusion: The results showed a high tendency for emotional eating, consumption of palatable foods, and cognitive dietary restraint in young adults, and these factors were considered determinants for eating disorders.

RESUMO Objetivo: O objetivo do estudo foi investigar as relações entre o índice de massa corporal, as razões para consumir alimentos palatáveis, o comer emocional, a restrição alimentar cognitiva e os comportamentos de desordem alimentar em jovens adultos. Métodos: Este estudo foi realizado com 800 jovens adultos, em Ancara, na Turquia. Foi aplicado um questionário composto por perguntas sobre características sociodemográficas, estado de saúde e instrumentos, incluindo o Eating Attitudes Test-26, o Emotional Appetite Questionnaire, a Palatable Eating Motives Scale e o The Three-Fator Eating Questionnaire, através de entrevistas presenciais. Resultados: De acordo com o Eating Attitudes Test-26, 17,2% dos homens e 27,7% das mulheres estavam em risco de desenvolver comportamentos alimentares desordenados (χ2=9,750, p=0,002). As pontuações médias do Three-Fator Eating Questionnaire-emotional eating, as subescalas de restrição cognitiva e as pontuações positivas e negativas do Emotional Appetite Questionnaire foram mais elevadas no sexo masculino do que no feminino (p<0,05). As pontuações médias da Palatable Eating Motives Scale - motivos de coping e de aumento da recompensa - foram mais elevadas no sexo feminino, enquanto a pontuação média para os motivos de conformidade foi significativamente mais elevada no sexo masculino. O índice de massa corporal, o Three-Fator Eating Questionnaire-subescala de contenção cognitiva, o Emotional Appetite Questionnaire-negativo e o PEMS-motores de conformidade foram encontrados como preditores do Eating Attitudes Test-26 (todos p<0,05). Conclusão: Os resultados mostraram uma elevada tendência para a alimentação emocional, o consumo de alimentos palatáveis e a restrição alimentar cognitiva em adultos jovens, sendo estes factores considerados determinantes para as perturbações alimentares.

Effect of Two Different Meal Compositions on 1-hour Plasma Ghrelin Levels in Young Men

@#Introduction: Calorie restriction is the main strategy for loosing body weight in obese individuals. However, persistence to this strategy is a major challenge. Ghrelin, a hormone that influences an individual to consume food by modulating the feelings of hunger. This effect may be influenced by the % fat composition of a meal. Materials and Methods: Twelve young male participants with normal BMI, were administered in random order one of 2 isocaloric meals after an overnight fast. The 2 meals contained either 31 or 52% fat. After a 7 day gap, cross-over of the participants was carried out and they consumed the other meal similarly. Ghrelin levels were measured after fasting and 1 hour after diet consumption. An appetite rating on a visual analogue scale (VAS) was used to measure perceived hunger and satiety before and after the meal. Results: When compared to the baseline values, an average of 34% and 20% decrease in ghrelin levels were noted after the high-fat meal (p<0.025), and low-fat meal respectively. Analysis of the VAS showed that feelings of hunger decreased, while feelings of satiety increased after the meal, however there was no difference between the two meals. Conclusion: Thus, within this study group, though the feelings of hunger and satiety was comparable, consumption of isocaloric high fat caused ghrelin levels to decrease within one hour post meal. This shows that manipulation of % fat of the diet can achieve lower post-meal ghrelin levels.

Ghrelin and appetite regulation: Mechanism and clinical application / 中华内分泌代谢杂志

The development of obesity is closely related to the disruption of central appetite regulation. Gastric growth hormone-releasing peptide is the only appetite-promoting peptide known to be present in the circulatory system. Ghrelin may act on the central homeostatic and hedonic feeding neural pathways to promote appetite and feeding behavior, and may be a new target for appetite regulation. In addition, Ghrelin is also involved in the regulation of energy homeostasis via promoting growth, regulating gastrointestinal function, and suppressing inflammatory response. Therefore, the research on the mechanism of ghrelin and its receptors will help understand the pathophysiological changes in the central appetite regulation process of obese patients, and to find potential targets for the treatment of obesity. In this paper, we focus on the molecular mechanism of appetite regulation by Ghrelin and its clinical application.

Effect of chewing behavior modification on food intake, appetite and satiety-related hormones: A Systematic Review

Purpose: Obesity has become a growing public health issue worldwide. Studies have shown that eating rate is one of the most important factors to consider in the strategies to prevent and/or treat obesity. Eating rate can be reduced through different strategies, such as an increase in oro-sensory exposure, the modification of food texture, and an increase in the number of chewing cycles. The aim of this systematic review was to analyze the available evidence regarding the effect of chewing behavior modification on the parameters that contribute to obesity. Methods: A systematic search was done on the electronic databases Pubmed, Cochrane Central Register of Controlled Trials, and Scopus, using the terms "mastication", "chewing", "chewing speed", "prolonged chewing", "number of chews", "masticatory cycles" "satiety" "satiety response" "appetite", "appetite regulation", "nutritional status" and "obesity". Results: A total of 23 intervention studies were selected that intervened in the participants' chewing behavior, either by reducing the eating rate, increasing oro-sensory exposure, food hardness or the number of chewing cycles. In most studies these interventions were effective at reducing food intake, subjective appetite and improving the plasma levels of satiety-related hormones and metabolites; moreover, they reduced body mass index in the long term. Conclusion: The currently available evidence seems to indicate that modifications to chewing behavior can bring with it a myriad of benefits for the treatment of obesity.

Propósito: La obesidad se ha convertido en un problema de salud pública creciente a nivel mundial. Investigaciones han demostrado que la tasa de ingesta es uno de los factores importantes a considerar en las estrategias para prevenir o tratar la obesidad. La tasa de ingesta puede reducirse a través de diferentes estrategias; el aumento de la exposición oro-sensorial, la modificación de la textura de los alimentos y el aumento en el número de ciclos masticatorios. El objetivo de esta revisión sistemática fue analizar la evidencia disponible sobre el efecto de la modificación de la conducta masticatoria sobre los parámetros que contribuyen a la obesidad. Métodos: Se realizó una búsqueda sistemática en las bases de datos electrónicas Pubmed, Cochrane Central Register of Controlled Trials y Scopus, con los términos "mastication", "chewing", "chewing speed", "prolonged chewing", "number of chews", "masticatory cycles" "satiety" "satiety response" "appetite", "appetite regulation", "nutritional status" y "obesity". Resultados: Se seleccionaron 23 estudios que intervenían en el comportamiento masticatorio de los participantes, ya sea reduciendo de la tasa de ingesta, aumentando la exposición oro-sensorial, dureza de los alimentos y número de ciclos masticatorios. Estas intervenciones resultaron ser efectivas para reducir la ingesta de alimentos, el apetito subjetivo y mejorar los niveles plasmáticos de las hormonas y metabolitos relacionados con la saciedad, además, a largo plazo, permitieron reducciones en el índice de masa corporal. Conclusión: La evidencia disponible actualmente parece señalar que las modificaciones en el comportamiento masticatorio pueden traer consigo múltiples beneficios para el tratamiento de la obesidad.

Fasting levels of appetite regulating hormones predict caloric intake at breakfast in a group of Chilean adolescents / Los niveles en ayunas de hormonas reguladoras del apetito predicen la ingesta energética en el desayuno en adolescentes

BACKGROUND: Appetite regulation is integral to food intake and is modulated by complex interactions between internal and external stimuli. Hormonal mechanisms which stimulate or inhibit intake have been characterized, but the physiologic effects of serum levels of such hormones in short-term appetite regulation have received little attention. AIM: To evaluate whether fasting levels of orexigenic/anorexigenic hormones were associated with energy intake at breakfast, served soon after drawing a fasting blood sample, in a group of adolescents. MATERIAL AND METHODS: Anthropometry, body composition and fasting blood levels of leptin, insulin, ghrelin, and orexin-A were measured in 655 Chilean adolescents aged 16.8 ± 0.3 years (52% males). Energy intake was measured at a semi-standardized breakfast. Associations between hormone levels and energy intake were studied using multivariate linear models. RESULTS: Thirty nine percent of participants were overweight/ obese. After an overnight fast, median values for leptin, insulin, ghrelin and orexin-A were 7.3 ng/mL, 6.7 IU/dL, 200.8 pg/mL, and 16.1 pg/mL, respectively. Participants ate on average 637 ± 239 calories at breakfast. In multivariable models, insulin levels were inversely and independently associated with caloric intake at breakfast (β = −18.65; p < 0.05), whereas leptin, ghrelin and orexin-A levels were positively and independently associated with intake: β= 5.56, β = 0.34 and β = 8.40, respectively, p < 0.05. CONCLUSIONS: Fasting leptin, ghrelin and orexin-A were positively associated with energy intake during breakfast provided soon after the blood draw. Insulin was negatively associated with energy intake. Modifiable factors influencing levels of appetite regulating hormones could be a potential target for influencing food intake.

ANTECEDENTES: La regulación del apetito es parte integral de la ingesta alimentaria y es modulada por complejas interacciones entre estímulos internos y externos. Se han caracterizado los mecanismos hormonales que estimulan o inhiben la ingesta, pero los efectos fisiológicos de los niveles séricos de tales hormonas en la regulación del apetito a corto plazo han recibido poca atención. OBJETIVO: Evaluar si los niveles en ayunas de hormonas orexigénicas/ anorexigénicas se asocian con la ingesta energética en el desayuno, entregado inmediatamente después de una muestra de sangre en ayunas, en un grupo de adolescentes. MATERIAL Y MÉTODO: Se efectuaron mediciones antropométricas, composición corporal y medición de niveles en ayunas de leptina, insulina, grelina y orexina-A en 655 adolescentes de 16,8 ± 0,26 años. La ingesta energética se midió en un desayuno semiestandarizado. Se estudiaron las asociaciones entre los niveles hormonales y la ingesta energética mediante modelos lineales multivariados. RESULTADOS: Los valores de leptina, insulina, grelina y orexina-A fueron 7,3 ng/mL, 6,7 UI/dL, 200,8 pg/mL y 16,1 pg/mL respectivamente. Los participantes comieron un promedio de 637 ± 239 calorías en el desayuno. Los niveles de insulina se asociaron inversa e independientemente con la ingesta del desayuno (β = −18,65; p < 0,05), mientras que los niveles de leptina, grelina y orexina-A se asociaron positiva e independientemente con la ingesta: β = 5,65; β = 0,34; β = 8,40, (p < 0,05). CONCLUSIONES: La leptina, grelina y orexina-A en ayunas se asociaron positivamente con la ingesta de energía durante el desayuno proporcionado poco después de la muestra de sangre. La insulina se asoció negativamente con la ingesta de energía. Los factores modificables que influyen en las hormonas reguladoras del apetito podrían ser un objetivo potencial para influir en la ingesta de alimentos.

Effectiveness of chia (Salvia hispanica L.) as an adjuvant therapy for Type 2 diabetes mellitus: A systematic review and meta-analysis / The Health Sciences Journal

INTRODUCTION@#Salba-chia (Salvia hispanica L.) is a popular functional food containing high levels of protein, total dietary fiber, and is an excellent source of α-linolenic acid. Chia seeds significantly decreases weight, suppresses appetite, and has a potential benefit in the management of Type 2 diabetes mellitus (T2DM). This study aimed to determine the effectiveness of chia seeds as an adjuvant treatment for T2DM.@*METHODS@#Randomized controlled trials from 1990 onwards involving Type 2 diabetic patients given chia seed were included. PubMed, Cochrane, ClinicalKey, Google Scholar, and Hinari were searched systematically using MeSH terms “chia”, “Salvia hispanica”, “dietary supplement”, and “diabetes”. The quality of trials was assessed using the Cochrane Collaboration tool. Data on the study design, blinding status, characteristics of participants, medications taken by participants, chia seed intervention, comparator, duration of intake, and interval of assessment were extracted. The percent change of outcome from baseline was compared between the chia and control groups.@*RESULTS@#Four randomized trials with a total of 213 diabetic patients were enrolled in the treatment group using ground salba-chia or the control group using bran. The supplementation of chia resulted in a statistically significant decrease in fasting glucose (-2.90 mmol/L; 95% CI, -3.08, -2.72; p < 0.001), waist circumference (-2.49 cm; 95% CI -2.81, -2.17; p < 0.001), total cholesterol (-2.72 mmol/L; 95% CI -3.68, -1.74; p < 0.001), HDL (-3.69 mmol/L; 95% CI -3.95, -3.42; p < 0.001), LDL (-3.22 mmol/L; 95% CI -4.08, -2.36; p < 0.001); and an increase adiponectin levels (6.50 mg/L; 95% CI 6.25, 6.25; p < 0.001).@*CONCLUSION@#Intake of chia seeds resulted in a statistically significant decrease in fasting blood glucose, waist circumference, total cholesterol levels, HDL and LDL cholesterol levels, and increased adiponectin. Chia seeds are generally safer and have lesser side effects compared to the placebo. Chia is effective as adjunctive treatment for Type 2 diabetic patients.

Tratamiento laparoscópico de una paciente con un leiomioma uterino gigante cavitado, con cambio degenerativo mucomixoide / Laparoscopic treatment of a patient with a cavitated giant uterine leiomyoma with mucomyxoid degenerative change

Resumen INTRODUCCIÓN: Un leiomioma con cambios degenerativos poco frecuentes es un desafío diagnóstico difícil de diferenciar de sus homólogos malignos, si se pretende fundamentarlo solo en lo advertido en las imágenes. CASO CLÍNICO: Paciente de 40 años de edad, enviada al servicio de Cirugía de mínima invasión en marzo del 2021 debido al aumento del perímetro abdominal, disminución del apetito y disnea de medianos esfuerzos. El ultrasonido abdomino-pélvico reportó que el útero estaba aumentado de tamaño, con miomas intramurales de medianos elementos. El endometrio heterogéneo. El ovario derecho tenía un quiste complejo, gigante, de 276 mm x 250 mm x 276 mm, con volumen de 10 000 cc. Además, esplenomegalia, hidronefrosis derecha y litiasis renal izquierda. Los marcadores tumorales se reportaron normales. En la cirugía por laparoscopia se observó un tumor que ocupaba toda la cavidad abdominal de 40 x 30 cm, adherido a la pared posterior del útero, con ambos ovarios sin alteraciones, sin líquido libre; se procedió a la histerectomía total. CONCLUSIONES: Los cambios degenerativos en los leiomiomas uterinos pueden distorsionar la estructura habitual del tumor y reflejarla en imágenes típicas de una tumoración quística de ovario; en el estudio inicial esto representa un desafío para el cirujano y debe considerarse parte del diagnóstico diferencial de las masas anexiales. En la paciente del caso, con cirugía de mínima invasión, se consiguió la resección completa de la pieza, a pesar del tamaño aumentado, con menores riesgos de complicaciones en la herida y menos dolor posoperatorio; las incisiones son pequeñas y con desenlaces estéticos favorables y menos días de estancia intrahospitalaria.

Abstract INTRODUCTION: A leiomyoma with rare degenerative changes is a diagnostic challenge difficult to differentiate from its malignant counterparts, if it is intended to be based only on imaging findings. CLINICAL CASE: 40-year-old female patient referred to the Minimally Invasive Surgery service in March 2021 due to increased abdominal perimeter, decreased appetite and dyspnea on medium exertion. Abdomino-pelvic ultrasound reported that the uterus was enlarged, with medium-element intramural fibroids. The endometrium was heterogeneous. The right ovary had a complex, giant cyst, 276 mm x 250 mm x 276 mm, with a volume of 10,000 cc. In addition, splenomegaly, right hydronephrosis and left renal lithiasis. Tumor markers were reported normal. Laparoscopic surgery showed a tumor occupying the entire abdominal cavity measuring 40 x 30 cm and attached to the posterior wall of the uterus, with both ovaries unaltered, with no free fluid; total hysterectomy was performed. CONCLUSIONS: Degenerative changes in uterine leiomyomas can distort the usual tumor structure and reflect it in images typical of an ovarian cystic tumor; in the initial study this represents a challenge for the surgeon and should be considered part of the differential diagnosis of adnexal masses. In the case patient, with minimally invasive surgery, complete resection of the specimen was achieved, despite the increased size, with less risk of wound complications and less postoperative pain; the incisions are small and with favorable esthetic outcomes and fewer days of in-hospital stay.

Continuous or interval aerobic exercise training reduces daily fructose intake in female Wistar rat / Exercício físico aeróbio contínuo ou intervalado reduz ingestão de frutose em ratas Wistar

ABSTRACT: Objctive: Fructose consumption has increased worldwide. Excessive fructose intake has been a risk factor for the increased metabolic syndrome disorder incidence. This study aimed to investigate the possible influence of two different exercise training methods, continuous and interval, on fructose intake. Methods: Thirty two-months-old female Wistar rats were divided into six groups: sedentary + water ; sedentary + fructose ; continuous training + water ; interval training + water ; continuous training + fructose ; interval training + fructose . Fructose was given in drinking water (10%). Continuous (40 minutes at 40% maximal speed) or interval training (28 minutes, 1 minute at 70%; 3 minutes at 35% maximal speed) sessions were carried out 3 days/week for 8 weeks. Results: Fructose consumption decreased food intake with a concomitant increase in fluid intake. Continuous and interval training did not modify food intake but progressively reduced fructose ingestion. In the 8th week, interval training + fructose and continuous training + fructose groups drank less fructose solution, 35% and 23%, respectively, than sedentary + fructose group. Conclusion: The findings indicate that both continuous and interval aerobic exercise training seem to modulate food behavior, possibly by mitigating the craving for sweetness, with interval training being more effective in reducing fructose intake than continuous exercise.

RESUMO: Objetivo: O consumo de frutose aumentou em todo o mundo. A ingestão excessiva de frutose tem sido implicada como um fator de risco do aumento da incidência de distúrbios da síndrome metabólica. Nesse contexto, este estudo teve como objetivo investigar a possível influência de dois métodos diferentes de treinamento físico, contínuo e intervalado, na ingestão de frutose. Metodos: Trinta ratas Wistar foram divididas em seis grupos: sedentário + água, sedentário + frutose, treinamento contínuo + água, treinamento intervalado + água, treinamento contínuo + frutose, treinamento intervalado + frutose. A frutose foi dada na água potável (10%). Foram realizadas sessões contínuas (40 minutos a 40% da velocidade máxima) ou intervaladas (28 minutos, 1 minuto a 70%; 3 minutos a 35%) três dias por semana durante oito semanas. Resultados: A ingestão de frutose diminuiu a ingestão alimentar, com um aumento concomitante da ingestão hídrica. O treinamento contínuo e intervalado não modificou a ingestão alimentar, mas reduziu progressivamente a ingestão de frutose. Na oitava semana, treinamento intervalado + frutose e treinamento contínuo + frutose beberam menos solução de frutose, 35% e 23%, respectivamente, do que sedentário + frutose. Conclusão: Os achados indicam que tanto o treinamento aeróbico contínuo quanto o intervalado parecem modular o comportamento alimentar, possivelmente por meio da mitigação do desejo por sabor doce, sendo o treinamento intervalado mais eficaz para reduzir a ingestão de frutose do que o exercício contínuo.

Chemical genetics technology regulates the activity of GLP-1 neurons and its effect on appetite / 中华内分泌代谢杂志

Objective:To conduct a glucagon like peptide-1(GLP-1)controllability model rat by chemical genetics, and observe the impact of GLP-1 neuron excitability on appetite.Methods:Fifteen rats were evenly divided into Green fluorescent protein(GFP)group, HM3D group, and HM4D group. Various combinations of adeno-associated virus(rAAV)were injected into the nucleus tractus solitarius(NTS). rAAV-GLP-1-cre and rAAV-GFP-dio were administered in rats of GFP group. The rats of HM3D group were injected with rAAV-GLP-1-cre and rAAV-HM3D-mCherry-dio while rAAV-GLP-1-cre and rAAV-HM4D-mCherry-dio were injected in rats of HM4D group . The optimal dose of clozapine N-oxide(CNO)was selected based on feeding behavior and body weight changes of rats after intraperitoneal injection of different doses of CNO. The controllability of GLP-1 neurons was confirmed by comparing with intraperitoneal injection of saline. The number of activated GLP-1 neurons in the NTS area and the expression of POMC neurons in the hypothalamus were detected 30 minutes after CNO injection.Results:GLP-1 neurons in the NTS area of rats were successfully labeled. The rat of HM3D group revealed a decrease in food intake( P=0.021)while the rat of HM4D group showed an increase( P=0.002), when given 1 mg/kg of CNO, no changes at the dose of 0.5 mg/kg and 3.0 mg/kg. Immunofluorescence showed that the activity of GLP-1 neurons in NTS of GFP group was lower than that of HM3D group( P=0.022), and higher compared with that of the HM4D group( P=0.049). The expression of GLP-1 neurons in NTS and POMC neurons in the hypothalamus of the HM3D group after intraperitoneal injection of CNO was also higher than that in the HM4D group( P=0.003). Conclusion:Using chemical genetics technology, GLP-1 controllability model rat could be successfully established via injecting varying combinations of rAAV into the NTS area of rat. Injection of 1 mg/kg CNO can effectively activate or inhibit the neuron to regulate appetite.

Chronic Spontaneous Urticaria in Adult Patients: Evaluating the Effect of Loratadine on Weight and Metabolic Syndrome (Urtikaria spontan kronik di kalangan pesakit dewasa: penilaian kesan loratadin terhadap berat badan dan sindrom metabolik) / Jurnal Sains Kesihatan Malaysia

@#Antihistamine is standard chronic spontaneous urticaria (CSU) therapy. Weight gain is a side effect of concern as prolonged high dose therapy is common. We investigated the effects of 12-weeks loratadine therapy on weight, appetite and parameters of metabolic syndrome (MetS). A cohort study was performed involving CSU patients aged ≥18 years. Patients with diseases or on drugs affecting weight or appetite were excluded. CSU was treated according to standard management. Weight, height, waist circumference (WC), body mass index (BMI) and blood pressure (BP), Urticaria Activity Score 7 (UAS7), Dermatology Life Quality Index (DLQI), hunger and satiety questionnaire, fasting blood sugar (FBS) and fasting lipid profile (FLP) were obtained at baseline, week 6 and week 12. Loratadine cumulative dose were determined. Thirteen (33.33 %) males and 26 (66.67 %) females aged 33.00 (12.00) years participated. Median weight was 62.55 (18.30) kg, BMI 24.60 (6.80) kg/m2, 13(33.33%) patients had normal weight, 12 (30.77%) overweight, 11 (28.21%) obese and 3 (7.69%) underweight. Significant weight gain was observed at week 6, 67.56 ± 16.14 kg vs 68.16 ± 16.95 kg, p < 0.05 and 67.56 ± 16.14 kg vs 64.73 ± 14.60 kg, p = 0.04 at week 12. Changes in BMI, WC, BP, FBS and FLP were insignificant. Three patients developed MetS. Hunger and satiety scores were unaffected. Loratadine induced weight gain despite no effects on appetite. Weight should be monitored in patients on long term loratadine therapy.

Fatores associados ao comportamento alimentar de idosos jovens e longevos do Sul do Brasil / Factors associated with eating behavior of young-old and oldest-old people from Southern Brazil

O objetivo deste estudo transversal com 6.974 idosos foi caracterizar o comportamento alimentar de idosos jovens e longevos determinado pela dificuldade funcional de se alimentar sozinho, autopercepção do apetite e número de refeições diárias, analisados pelo modelo de regressão de Poisson. Os idosos jovens alimentavam-se com mais facilidade e apresentavam melhor autopercepção do apetite enquanto os longevos realizavam maior número de refeições diárias. Na análise ajustada, a pior autopercepção do apetite foi relacionada com pior autopercepção de saúde geral entre os idosos jovens, e sexo feminino entre os longevos. Idosos jovens apresentaram como fator preditivo positivo do número de refeições o fato de saírem de casa e apresentarem peso adequado e nenhuma doença crônica. Entre os longevos sair de casa foi um preditor negativo do número de refeições. Assim, os fatores determinantes de pior comportamento alimentar foram ser longevo, viver sem companheiro, pior autopercepção de saúde e de saúde oral.

The objective of this cross-sectional study with 6974 old people was to characterize the eating behavior of the young-old and oldest-old determined by the functional difficulty of eating by oneself, self-perception of appetite and number of daily meals, analyzed by the Poisson regression model. Young-old people feed more easily by themselves and had better self-perception of appetite; the oldest-old ones had more daily meals. In the adjusted analysis, poor self-perception of appetite was related with poor self-perception of general health among younger elderly, and being a woman among the oldest-old ones. Younger elderly presented, as a positive predictive factor the number of meals, leaving home and having adequate weight and no chronic disease. Among the oldest-old ones, leaving home was a negative predictor of the number of meals. Thus, the determining factors for worse eating behavior were being oldest-old, living without a partner, poor self-rated health and oral health.

Dronabinol en manejo de apetito y pérdida de peso en pacientes con cáncer terminal, VIH, cuidados paliativos y vejez. Revisión de la literatura / Dronabinol in appetite management and weight loss in patients with terminal cancer, HIV, palliative care and old age. Literature review

Resumen: Introducción: La caquexia es un síndrome asociado al cáncer avanzado, VIH, pacientes en quimioterapia y quienes tienen seguimiento en cuidados paliativos. La prevalencia es de 25% de los pacientes con diagnóstico de cáncer, 26% en quienes reciben quimioterapia y de 14 a 38% de pacientes con VIH. Un pilar para el manejo es el cannabis debido al efecto del delta-9-tetrahidrocanabinol (THC), del cual se derivó el dronabinol, un fármaco desarrollado para estimular apetito y ganancia de peso. El objetivo de esta revisión bibliográfica es obtener la información sobre los cannabinoides y la evidencia más sólida existente con respecto al uso del dronabinol en pacientes que han presentado pérdida de peso y apetito. Material y métodos: Revisión de la bibliografía con buscador PubMed con las palabras clave Palliative care (cuidados paliativos), Cannabinoids (cannabinoides), cachexia (caquexia), Dronabinol (dronabinol), Appetite (apetito), de 1990 a 2018, limitado a humanos, obteniendo 259 artículos, eliminando 222 por repetirse o tener poca relevancia, dejando 37 artículos para análisis. Resultados: De 37 artículos revisados, nueve fueron estudios experimentales, 10 revisiones sistematizadas, un metaanálisis y 16 artículos de recomendaciones y sugerencias de manejo. Conclusión: El manejo del apetito y pérdida de peso en pacientes en cuidados paliativos, VIH, ancianos o en quimioterapia debe ser multidisciplinario, involucrando nutriólogos, psicólogos y médicos, ajustando el manejo a las características individuales que manifiesten. El dronabinol es un fármaco de primera elección para el manejo de dichos síntomas cuando la historia natural de la enfermedad se acompaña de náusea, vómito o dolor.

Abstract: Introduction: Cachexia is a syndrome associated with advanced cancer, HIV, patients on chemotherapy and those who are followed in palliative care. The prevalence is 25% of patients diagnosed with cancer, 26% in those receiving chemotherapy and 14 to 38% of patients with HIV. A mainstay for management is cannabis, due to the effect of delta-9-tetrahydrocannabinol (THC) from which dronabinol, a drug developed to stimulate appetite and weight gain, was derived. The aim of this literature review is to obtain information on cannabinoids and the strongest existing evidence regarding the use of dronabinol in patients who have presented weight and appetite loss. Material and methods: Literature review with PubMed search engine with the keywords Palliative care, Cannabinoids, cachexia, Dronabinol, Appetite, from 1990 to 2018, limited to humans, obtaining 259 articles, eliminating 222 for repetition or low relevance, leaving 37 articles for analysis. Results: Out of 37 articles reviewed 9 were experimental studies, 10 systematized reviews, 1 meta-analysis and 16 articles of recommendations and management suggestions. Conclusion: The management of appetite and weight loss in palliative care, HIV, elderly or chemotherapy patients should be multidisciplinary, involving nutritionists, psychologists and physicians, adjusting the management to the individual characteristics manifested. Dronabinol is a drug of first choice for the management of these symptoms when the natural history of the disease is accompanied by nausea, vomiting or pain.

Apetite emocional em situações negativas e padrão alimentar de mulheres adultas / Emotional appetite in negative situations and dietary patterns of adult women / Apetito emocional en situaciones negativas y el patrón alimentario de mujeres adultas

Objetivo: Verificar se e quais padrões alimentares podem estar associados ao apetite emocional em mulheres acompanhadas pelo Sistema Único de Saúde (SUS). Métodos: Estudo quantitativo, transversal e analítico realizado em 20 Centros de Saúde da Família do SUS, entre 2016 e 2017, com mulheres de 19 a 59 anos, em idade reprodutiva e alfabetizadas. Coletaram-se dados de peso, altura e circunferência da cintura, e aplicou-se o Questionário de Apetite Emocional (QUEAPEM), para avaliar o apetite emocional, e o Questionário de Frequência Alimentar, para avaliar o consumo alimentar, analisado na forma de padrões alimentares derivados por análise fatorial por meio de testes de esfericidade de Barllet e Kayse-Meyer-Olkin. Verificou-se relação entre os padrões alimentares e a dimensão do apetite emocional pelo teste de Spearman, considerando significativos os valores de p<0,05. Resultados: Ao total, 149 mulheres participaram do estudo, com idade média de 34,3 ± 8,6 anos. A maioria das mulheres (n= 88; 59%) encontra-se com excesso de peso, sendo 25,5% (n=38) com obesidade. Identificaram-se três padrões alimentares que juntos explicaram 16,8% da variabilidade da dieta, denominados de "denso em energia", "saudável" e "tradicional". Houve correlação entre o padrão alimentar "tradicional" e a presença de apetite emocional em situações negativas (p<0,05), não havendo correlação com os demais padrões. Conclusão: A identificação de três padrões alimentares permitiu um melhor entendimento da alimentação das mulheres estudadas, além de detectar uma associação inversa, embora fraca, entre o padrão alimentar "tradicional" e o apetite emocional em situações negativas.

Objective: To check whether and what dietary patterns may be associated with emotional appetite in women served by the Brazilian Unified Health System (Sistema Único de Saúde ­ SUS). Methods: This quantitative analytical cross-sectional study was conducted in 20 SUS Family Health Centers between 2016 and 2017 with literate women aged 19 to 59 years at reproductive age. Data on weight, height, and waist circumference were collected and the Emotional Appetite Questionnaire (Questionário de Apetite Emocional ­ QUEAPEM) was applied to assess emotional appetite. The Food Frequency Questionnaire was used to assess food intake in the form of dietary patterns derived from factor analysis using Barllet's and Kayse-Meyer-Olkin sphericity tests. The relationship between dietary patterns and emotional appetite dimension was checked by the Spearman's test with significant values set at p<0.05. Results: Participants were 149 women with a mean age of 34.3 ± 8.6 years. Most women (n= 88, 59%) exhibited excess weight, with 25.5% (n=38) of them being obese. Three dietary patterns were identified and together explained 16.8% of the variability of the diet. They were labelled "energy dense", "healthy" and "traditional". There was a correlation between the "traditional" dietary pattern and presence of emotional appetite in negative situations (p<0.05), with no correlation with the other patterns. Conclusion: The identification of three dietary patterns allowed a better understanding of the diet of the studied women and detected an inverse, although weak, association between the "traditional" dietary pattern and emotional appetite in negative situations.

Objetivo: Verificar si y cuáles son los patrones alimentarios que se puede asociar con el apetito emocional de mujeres asistidas en el Sistema Único de Salud (SUS). Métodos: Estudio cuantitativo, transversal y analítico realizado en 20 Centros de Salud de la Familia del SUS entre 2016 y 2017 con mujeres entre 19 y 59 años con edad reproductiva y alfabetizadas. Se recogieron los datos del peso, la altura y la circunferencia de la cintura y se ha aplicado el Cuestionario de Apetito Emocional para evaluar el apetito emocional y el Cuestionario de Frecuencia Alimentaria para evaluar el consumo alimentario analizado en forma de patrones alimentarios derivados por el análisis factorial a través de las pruebas de Barllet y de Kayse-Meyer-Olkin. Se ha verificado la relación entre los patrones alimentarios y la dimensión del apetito emocional por la prueba de Spearman considerándose significativos los valores de p<0,05. Resultados: En total, 149 mujeres con edad media de 34,3 ± 8,6 años participaron del estudio. La mayoría de las mujeres (n= 88; 59%) tiene exceso de peso y el 25,5% (n=38) son obesas. Se ha identificado tres patrones alimentarios que juntos han explicado el 16,8% de la variabilidad de la dieta los cuales se les han nombrado de "denso en energía", "saludable" y "tradicional". Hubo correlación entre el patrón alimentario "tradicional" y la presencia del apetito emocional en situaciones negativas (p<0,05) sin correlación con los demás patrones. Conclusión: La identificación de tres patrones alimentarios ha permitido una mejor comprensión de la alimentación de las mujeres estudiadas además de identificar una asociación inversa, aunque débil, entre el patrón alimentario "tradicional" y el apetito emocional en situaciones negativas.

A single session of low-volume high-intensity interval and moderate-intensity continuous exercise elicits a transient reduction in ghrelin levels, but not in post-exercise energy intake in obese men

ABSTRACT Objective: This study investigated the acute effects of high-intensity interval (HIIE) and moderate-intensity continuous (MICE) exercise on ghrelin levels in obese men. Subjects and methods: A total of 10 obese men (age 27.6 ± 1.8 years, body mass index 35.4 ± 4.5 kg/m², body fat 39.9 ± 2.1%) performed two exercise sessions in a randomized order: HIIE (10 × 1 min intervals at 90% of the maximal heart rate [HRmax] interspersed by 1 min of active recovery) and MICE (20 min at 70% of the HRmax). Ghrelin levels were assessed pre-, post- and 1h post-exercise, and energy intake was assessed 1h post-exercise through an ad libitum meal. Results: HIIE and MICE showed a trend to decrease ghrelin levels immediately post-exercise (-14.1 ± 21.6% and −9.6 ± 23.8%, respectively, p = 0.07) and decreased 1h post-exercise (-12.7 ± 31.8% and −13.8 ± 21.7%, respectively, p < 0.05). No changes were observed for post-exercise energy intake (p > 0.05). There was a positive correlation between the change in ghrelin levels and post-exercise energy intake only for HIIE (r = 0.63, p = 0.05). Conclusion: In summary, a single session of HIIE and MICE elicits a reduction on ghrelin levels without changing post-exercise energy intake in obese men.

Comprometimento do apetite e fatores associados em pessoas idosas hospitalizadas com câncer / Impairment of appetite and associated factors in older adults hospitalized with cancer

Resumo Objetivo Investigar o comprometimento do apetite em pessoas idosas hospitalizadas com câncer e sua associação com estado nutricional e presença de caquexia. Métodos Estudo transversal realizado com pessoas idosas de ambos os sexos, diagnosticadas com neoplasia maligna, de julho de 2017 a março de 2019 em um hospital universitário. A amostra final foi composta por 90 pacientes. O comprometimento do apetite foi identificado pelo Questionário de Apetite e Sintomas para Pacientes com Câncer (CASQ) e o estado nutricional pela Avaliação Subjetiva Global Produzida pelo Próprio Paciente (ASG-PPP). A presença de caquexia foi avaliada pela perda de peso >5% nos últimos 6 meses; ou índice de massa corporal (IMC) <20 kg/m2 e perda de peso >2%; ou índice de músculo esquelético apendicular consistente com sarcopenia e perda de peso >2%. Resultados Houve predomínio de indivíduos do sexo masculino (56,7%), autodeclarados não brancos (56,7%), com tumores localizados no trato gastrointestinal (75,6%) e mediana de idade de 67 anos. 75,6% dos indivíduos apresentaram comprometimento do apetite, 57,8% suspeita de desnutrição ou desnutrição de algum grau, 54,4% caquexia e 92,2% necessidade de intervenção nutricional. Houve associação entre as categorias do CASQ com estado nutricional (p=0,001) e presença de caquexia (p=0,050). Após análise de regressão logística, a desnutrição permaneceu associada ao comprometimento do apetite [OR: 4,68 (IC 95%: 1,50-14,56), p=0,008]. Conclusão A presença de desnutrição aumentou as chances de comprometimento do apetite, o que reforça a necessidade da triagem e intervenção nutricional precoces, a fim de reduzir e/ou evitar os agravos nutricionais.

Abstract Objective To investigate appetite impairment in older adults hospitalized with cancer and its association with nutritional status and cachexia. Method A cross-sectional study, conducted with older adults men and women diagnosed with malignant neoplasia from July 2017 to March 2019 at a university hospital. The final sample consisted of 90 patients. Appetite was evaluated using the Cancer Appetite and Symptom Questionnaire (CASQ) and nutritional status was determined using the Patient-Generated Subjective Global Assessment (PG-SGA). Presence of cachexia was assessed by weight loss >5% in the last 6 months; or body mass index (BMI) <20 kg/m2 and weight loss >2%; or appendicular skeletal muscle index consistent with sarcopenia and weight loss >2%. Results There was a predominance of male (56.7%) self-declared non-white individuals (56.7%), with tumors in the gastrointestinal tract (75.6%) and median age of 67.0 years. 75.6% of the individuals have impaired appetite, 57.8% suspected malnutrition or malnutrition of some degree, 54.4% cachexia and 92.2% needed nutritional intervention. There was significant association between CASQ categories with nutritional status (p= 0.001) and presence of cachexia (p=0.050). After logistic regression analysis, malnutrition remained associated with impaired appetite assessed by CASQ score [OR: 4.68 (CI 95%: 1.50-14.56), p=0.008] Conclusion The presence of malnutrition increased the chances of appetite impairment, which reinforces the need for early nutritional screening and intervention, in order to reduce and/or avoid nutritional problems.

The effects of kefir in mixed meals on appetite and food intake: a randomized cross-over trial / Os efeitos do quefir em refeições mistas sobre o apetite e a ingestão de alimentos: um estudo randomizado cruzado

ABSTRACT Objective The natural probiotic kefir is fermented milk, and may have effects on satiety and voluntary energy intake. This randomized crossover trial aimed to determine whether kefir, consumed with low- or high-glycemic index meals, affects appetite and subsequent food intake. Methods Twenty four healthy females aged 21-24 years, were recruited from Erciyes University and the surrounding community. The participants were submitted to three different breakfasts: a low glycemic index accompanied by milk, a low glycemic index with kefir, and a high glycemic index with kefir, with a 1-week washout period between meals. At 0, 15, 30, 60, 90, 120, 150, and 180 minutes after the meal, appetite ratings were measured by the visual analog scale, and then ad libitum lunch was served. Results No differences in appetite scores and voluntary energy intake were detected between the test meals. Furthermore, palatability ratings were similar between test meals, except for the higher score of high glycemic index kefir for overall palatability. Conclusion This study demonstrated that adding kefir to a high glycemic index meal may prevent increases in appetite and food intake, resulting in postprandial responses similar to those of a low glycemic index meal. These findings might enable the development of novel dietary strategies based on appetite regulation to treat or prevent obesity, particularly for Western societies. This trial was registered at ClinicalTrials.gov under the process NCT03636217.

RESUMO Objetivo O quefir probiótico natural é um leite fermentado, e pode ter alguns efeitos sobre a saciedade e a ingestão voluntária de energia. Este ensaio cruzado randomizado teve como objetivo determinar se o quefir consumido com uma refeição de baixo ou alto índice glicêmico teria afetado o apetite e a ingestão de alimentos subsequente. Métodos Vinte e quatro mulheres saudáveis, com idades entre 21 e 24 anos, foram recrutadas na Universidade de Erciyes e na comunidade circundante. Todas as participantes foram submetidas a três cafés da manhã diferentes: um baixo índice glicêmico e leite, um baixo índice glicêmico e quefir, e um alto índice glicêmico e quefir, com um período de lavagem de 1 semana entre as refeições. Aos 0, 15, 30, 60, 90, 120, 150 e 180 minutos após a refeição, as classificações de apetite foram medidas por escala analógica visual e, em seguida, o almoço ad libitum foi servido. Resultados Não foram detectadas diferenças nos escores do apetite e na ingestão voluntária de energia entre as refeições do teste. Além disso, as classificações de palatabilidade foram semelhantes entre as refeições de teste, exceto o maior escore de alto índice glicêmico quefir para palatabilidade geral. Conclusão Este estudo demonstrou que a adição de quefir a uma refeição com alto teor de índice glicêmico pode impedir o aumento do apetite e da ingestão de alimentos, resultando em respostas pós-prandiais semelhantes a uma refeição com baixo teor de índice glicêmico. Esses achados poderiam permitir o desenvolvimento de novas estratégias dietéticas baseadas na regulação do apetite para tratar ou prevenir a obesidade, particularmente para a sociedade ocidental. Esse julgamento foi registado na ClinicalTrials.gov como NCT03636217.
