High resting energy expenditure in women with episodic migraine: exploring the use of predictive formulas.

Introduction: Migraine is a common and disabling primary headache, and its pathophysiology is not fully understood. Previous studies have suggested that pain can increase humans' Resting Energy Expenditure (REE). However, no previous study has investigated whether the REE of individuals with migraine differs from the general population. Therefore, this study aims to assess whether the REE of women with migraine differs from that of women without headaches. We also tested the accuracy of REE predictive formulas in the migraine patients. Methods: This cross-sectional study involves 131 adult women aged between 18 and 65 years, 83 with migraine and 48 without (controls). We collected clinical, demographic, and anthropometric data. Migraine severity was measured using the Migraine Disability Test and Headache Impact Test, version 6. The REE was measured by indirect calorimetry, and it was compared with the predicted REE calculated by formulas. Results: Patients with migraine had higher REE when compared to controls (p < 0.01). There was a positive correlation between REE and the patient-reported number of migraine attacks per month (Rho = 0.226; p = 0.044). Mifflin-St Jeor and Henry and Rees were the predictive formulas that have more accuracy in predicting REE in women with migraine. Discussion: Considering the benefits of nutritional interventions on treating migraines, accurately measuring REE can positively impact migraine patient care. This study enhances our understanding of the relationship between pain and energy expenditure. Our results also provide valuable insights for healthcare professionals in selecting the most effective predictive formula to calculate energy expenditure in patients with migraine.

Ginger supplementation does not increase energy expenditure in female adults.

Food components with thermogenic properties are promising antiobesity agents. Ginger (Zingiber officinale Rosc.) bioactive compounds have a capsaicin-like vanillyl portion, which has been attributed to thermogenic effect in previous experimental studies. However, studies conducted in humans have evaluated only the acute thermogenic effect of ginger, and demonstrated contradictory results. We evaluated the effect of long-term consumption of dry ginger extract on the resting energy expenditure (REE) of female adults with high body adiposity. METHODS: This is a secondary analysis of a randomized, double-blind, placebo-controlled clinical trial (NCT02570633). Participants age 18 to 60 y were randomly assigned into two groups: Intervention (600 mg of ginger extract daily) and placebo (cellulose). The intervention lasted 3 mo. Anthropometric measurements, blood pressure, and REE were assessed at each visit. RESULTS: A total of 66 female participants with high body adiposity were included in the analysis (mean age: 29 y [range, 20-55 y]; body mass index: 23.3 ± 2.7), with 30 participants in the ginger group and 36 in the placebo group. There were no significant differences in baseline characteristics between the groups. No differences were observed for group × time interaction on REE. Body composition and blood pressure followed the same pattern (all P > 0.05). CONCLUSIONS: Ginger extract consumption for 3 mo did not change the REE, anthropometric, and clinical data of female adults with excess adiposity.

Acute effects of dry extract of ginger on energy expenditure in eutrophic women: A randomized clinical trial.

BACKGROUND & AIMS: The thermic effect of food (TEF) is one of the components of total energy expenditure (TEE). Some bioactive compounds present in food could be useful to increase TEE. In this context, ginger has been extensively used as a thermogenic food despite no clear effect has been demonstrated yet. Herein, we evaluated the acute thermogenic effect of gingerol, a bioactive compound present in ginger, in healthy women. METHODS: We carried out a randomized double-masked, cross-over and placebo-controlled clinical trial with 20 healthy eutrophic women. Anthropometric, body composition, indirect calorimetry and clinical variables were collected at baseline and throughout the intervention phase. A standardized breakfast was offered together with two dry extract of ginger capsules (5% gingerol) or a placebo (cellulose). Indirect calorimetry, blood pressure, heart rate, axillary temperature and blood collection were assessed at baseline and thereafter, at 30, 60, 120, 180 and 240 min postprandial. The analyses were repeated with a minimum of seven days' washout period. RESULTS: Ginger intake did not increase the TEF of a standardized breakfast compared to the placebo. Oxygen consumption, respiratory quotient, blood pressure, heart rate, axillary temperature and metabolic profile were not different as well. CONCLUSIONS: Our data show that gingerol did not modify the acute TEF in healthy women. More studies in human subjects, using different concentrations of gingerol, administration methods and intervention type (chronic effect) are necessary to clarify the putative thermogenic effect of ginger.

Altered Serum Levels of Renin-Angiotensin System Markers in Migraine.

OBJECTIVE: To compare the serum levels of renin-angiotensin system (RAS) components between patients with migraine and healthy controls, and to evaluate whether these levels are associated with migraine severity. We hypothesized that migraine would be associated with the activation of the inflammatory arm of the RAS, possibly leading to increased levels of angiotensin (Ang) II. BACKGROUND: Recent studies have proposed the use of drugs that interfere with RAS, a hormonal system primarily implicated in blood pressure regulation, as a prophylactic strategy for migraine. However, no previous studies have directly assessed RAS components in migraine. METHODS: This was a cross-sectional study involving 30 patients with episodic migraine who were in the interictal period and 20 healthy controls. This study was conducted at Hospital das Clínicas (Universidade Federal de Minas Gerais, Belo Horizonte, Brazil) outpatient clinic. Headache severity was evaluated using the Headache Impact Test, version 6 (HIT-6) and the Migraine Disability Test (MIDAS) questionnaires. Given that migraine is comorbid with mood disorders, depressive and anxious symptoms were evaluated using the Beck Anxiety and Depression Inventories (BDI and BAI), respectively. Clinical and demographic data were also collected. Serum levels of angiotensin-converting enzyme (ACE), ACE2, Ang II, and Ang (1-7) were measured by enzyme-linked immunosorbent assay. RESULTS: Patients with migraine and controls were comparable in age, body mass index, blood pressure, and depressive and anxious symptoms. Patients with migraine showed lower levels of ACE [85.2 (66.8, 101.2) vs 65.5 (54.2, 77.5); P = .005] and lower ACE/ACE2 ratio [4.3 (3.4, 5.2) vs 3.5 (2.9, 4.1); P = .032] than controls. Conversely, patients with migraine had higher levels of Ang II [309.7 ± 147.4 vs 605.4 ± 200.4; difference: -287.1 (95% CI: -391.4--182.8), P < .001] and Ang (1-7) [214.4 ± 155.8 vs 397.9 ± 217.9; difference: -184.6 (95% CI: -296.7--72.6), P = .001] than controls. There were no correlations between RAS serum markers and migraine severity scores (HIT and MIDAS) or depressive and anxious symptoms (BDI and BAI) (P > .05). CONCLUSIONS: Altogether, our results suggest the participation of RAS in migraine pathophysiology, but not in its severity.

Double-blind placebo-controlled randomized clinical trial of ginger (Zingiber officinale Rosc.) in the prophylactic treatment of migraine.

BACKGROUND: Previous studies have shown an analgesic effect of ginger in the acute treatment of migraine, and there is anecdotal evidence of its efficacy in migraine prophylaxis. OBJECTIVE: This study aimed to evaluate the potential of ginger to prevent migraine attacks. METHODS: This double-blind, placebo-controlled randomized clinical trial took place at the Headache Clinic, Universidade Federal de Minas Gerais (Belo Horizonte, Minas Gerais, Brazil), involving 107 patients. Only subjects diagnosed with episodic migraine, aged between 18 and 60 years old, and who were not taking any prophylactic medication, were enrolled in the study. After one month of observation, subjects selected for the study were randomized 1:1 into placebo and treatment groups. Patients received capsules three times per day of 200 mg of dry extract of ginger (5% active ingredient) or placebo (cellulose) for three months. Visits were performed monthly and the patients were asked to fill in a migraine diary. The adherence to treatment was evaluated by counting capsules. RESULTS: The percentage of patients who responded to treatment (i.e. a reduction of 50% in the number of migraine attacks at the end of treatment) did not differ between the groups. There was a decrease in the number of days with severe pain, analgesic use for acute migraine and duration of migraine attacks in both groups, without significant difference between ginger and placebo groups. CONCLUSIONS: Ginger provides no greater benefit in the prophylactic treatment of migraine when compared to placebo. This trial is registered at ClinicalTrials.gov (NCT02570633).

Nutritional intervention may improve migraine severity: a pilot study.

OBJECTIVE: Although some studies have investigated the role of nutritional intervention on migraine, they had focused on triggers or on weight change and, to the best of our knowledge, none studied diet quality. OBJECTIVE: To investigate whether nutritional intervention focused on improving diet quality and healthy weight can promote improvement in clinical parameters of women with migraine. METHODS: Non-controlled and non-randomized intervention study conducted for 90 days. Women received an individualized diet meal plan and nutritional orientation according to their nutritional diagnosis. Anthropometric, clinical and nutritional data were measured once a month. Diet energy content and macronutrients were evaluated using 24-hour dietary recall. Diet quality was assessed through the Brazilian Healthy Eating Index-Revised (BHEI-R). The Migraine Disability Assessment and Headache Impact Test version 6 were used to assess the severity of migraine, and the Beck Depression Inventory evaluated depressive symptoms. RESULTS: Fifty-two women aged 44.0 ± 13.0 years were enrolled. Anthropometric characteristics, energy, macronutrients and fiber intake did not change after intervention. However, the BHEI-R scores improved after 60 and 90 days of intervention. Concurrent to this, the Beck Depression Inventory scores and Headache Impact Test scores decreased after 60 and 90 days, respectively. The change in the BHEI-R score was negatively correlated with the migraine severity as assessed by the Headache Impact Test at the end of the intervention. CONCLUSIONS: We concluded that the management of diet quality may be a good strategy for improving migraine severity, regardless of the nutritional status and weight change.

RESUMO Estudos investigaram o papel da intervenção nutricional, focada no consumo de alimentos "gatilhos" ou na alteração de peso, na melhora da migrânea. Porém, mudanças na qualidade da dieta ainda não foram abordadas. Objetivo Investigar se intervenção nutricional focada na qualidade da dieta e peso saudável pode melhorar parâmetros clínicos em mulheres com migrânea. Métodos Estudo de intervenção, não controlado e não randomizado. As mulheres receberam plano alimentar individualizado e orientações nutricionais, conforme o diagnóstico nutricional. Dados antropométricos, clínicos e alimentares foram medidos uma vez por mês durante três meses. Recordatório alimentar de 24 horas forneceu informações sobre o consumo alimentar. Qualidade da dieta foi avaliada pelo Índice Brasileiro de Alimentação Saudável (IQD-R). Os questionários Migraine Disability Test (MIDAS) e Headache Impact Test, versão 6 (HIT-6) avaliaram a incapacidade gerada pela enxaqueca e o Inventário de Depressão de Beck (BDI) investigou sintomas depressivos. Resultados Cinquenta e duas mulheres com 44,0 ± 13,0 anos participaram da amostra. Características antropométricas e consumo de energia, macronutrientes e fibras não se alteraram depois da intervenção. No entanto, os escores do IQD-R melhoraram após 60 e 90 dias de intervenção. Os escores do BDI e do HIT-6 diminuíram após 60 e 90 dias, respectivamente. A mudança no escore do IQD-R correlacionou de maneira negativa com a gravidade da enxaqueca avaliada pelo HIT-6 ao final da intervenção. Conclusões O manejo da qualidade da dieta pode ser estratégia para melhorar a gravidade da migrânea, independente do estado nutricional e da mudança de peso dos pacientes.

Double-blind placebo-controlled randomized clinical trial of ginger ( Zingiber officinale Rosc.) addition in migraine acute treatment.

BACKGROUND: Previous studies have demonstrated the analgesic effects of ginger in different conditions, but evidence about its efficacy in migraine treatment is scarce. OBJECTIVE: This study aimed to evaluate the potential of ginger to improve acute migraine as an add-on strategy to standard treatment. METHODS: A double-blind placebo-controlled randomized clinical trial in the emergency room of a general hospital was conducted. Patients who sought medical care at the time of migraine attack were enrolled in this study. Only adults with episodic migraine (one to six migraine attacks per month) with or without aura were included. Sixty participants were randomized into two groups in which they received 400 mg of ginger extract (5% active ingredient) or placebo (cellulose), in addition to an intravenous drug (100 mg of ketoprofen) to treat the migraine attack. Patients filled a headache diary before, 0.5 h, 1 h, 1.5 h and 2 h after the medication. Pain severity, functional status, migraine symptoms and treatment satisfaction were also recorded. RESULTS: Patients treated with ginger showed significantly better clinical response after 1 h ( p = 0.04), 1.5 h ( p = 0.01) and 2 h ( p = 0.04). Furthermore, ginger treatment promoted reduction in pain and improvement on functional status at all times assessed. CONCLUSIONS: The addition of ginger to non-steroidal anti-inflammatory drugs may contribute to the treatment of migraine attack. This trial is registered at ClinicalTrials.gov (NCT02568644).

Adesão de Servidores Públicos a Programa deQualidade de Vida e Intervenção Nutricional / Public Employees Adherence to Life Quality Program andNutritional Intervention

Trata-se de estudo de intervenção nutricional não controlado, com duração de três meses, que objetivou avaliar a adesão deservidores públicos a programa de qualidade de vida e intervenção nutricional. Realizou-se avaliação nutricional, orientaçõesindividualizadas e aplicação de questionário referente à adesão para os participantes que abandonaram o acompanhamentonutricional. Iniciaram o estudo 52 indivíduos, a maioria mulheres (76,9%), com média de 40,8 ± 8,9 anos. Não foramobservadas alterações significativas após intervenção nutricional. A taxa de abandono ao acompanhamento nutricionalfoi de 55,8%, sendo que 78,3% destes desistiram das demais atividades do programa. Os motivos da baixa adesão foraminsatisfação com horário das atividades (44,4%), falta de motivação (27,8%) e problemas de saúde (22,2%). Dentre os servidoresque continuaram a atividade física e não retornaram à consulta nutricional, 60,0% relataram dificuldade em deixaro trabalho para comparecer às avaliações e 40,0% não se sentiram motivados a retornar. A baixa adesão ao programa e àintervenção nutricional pode ter contribuído para ausência de alteração alimentar e antropométrica. Torna-se importanteavaliar estratégias de intervenção para reestruturar os métodos utilizados e aumentar a participação dos indivíduos.

It is a non-controlled nutritional intervention study with three months length, which aimed to evaluate the adherence ofpublic employees to life quality program and nutritional intervention. Nutritional evaluation and individualized guidelineswere made and questionnaires regarding accession to the participants who left the nutritional monitoring. Began the study52 individuals, mostly women (76,9%), with an average of 40,8 ± 8,9 years old. Any meaningful alteration was observedafter nutritional intervention. The rate of abandonment to nutritional intervention 55,8% and 78,3% of them gave up theother program activities. The main reason for abandonment were dissatisfaction with the time of activities (44,4%), lackof motivation (27,8%), and health problems (22,2%). Among employees who continued the physical activity and did notreturned to nutritional consultation, 60,0% reported difficulty in leaving job to attend the evaluations and 40,0% did notfeel motivated to return. The low adherence to the program and nutritional intervention may have contributed to the lackof dietary and anthropometric modification. Evaluate intervention strategies becomes important to restructure the methodsand increase the participation of individuals.

O objetivo com esta pesquisa foi caracterizar o estado nutricional e o consumo alimentar de pacientes com síndrome de ovários policísticos (SOPC). Trata-se de estudo transversal realizado com portadoras de SOPC atendidas pela Equipe de Nutrição em serviço de atenção secundária à saúde. Foram obtidas informações sociodemográficas e perfil de saúde, medidas antropométricas, dados bioquímicos e do consumo alimentar. Participaram do estudo 54 mulheres, com média de 31,31± 5,76 anos, sendo 63% classificadas com algum grau de obesidade, 74,1% com risco cardiovascular segundo a razão cintura-quadril e 90,8% com circunferência de cintura aumentada. Houve correlação positiva entre a resistência insulina, mensurada pelo índice HOMA-IR, e índice de massa corporal (r=0,729; p=0,028). Além disso, houve elevada prevalência de consumo insuficiente de calorias (73,6%), carboidratos (54,7%) e micronutrientes (cálcio - 96,2%; ferro - 98,1%), contrastando com 71,7% de ingestão excessiva de lipídeos. Não houve associação entre estado nutricional, parâmetros bioquímicos e consumo alimentar (p>0,05). Concluiu-se que pacientes diagnosticadas com SOPC apresentam alta prevalência de obesidade e inadequações nutricionais, denotando importância de medidas de intervenção nutricional como parte do tratamento não farmacológico.

The present study aims at characterizing the nutritional status and food intake of patients with Polycystic Ovary Syndrome (PCOS). It is a cross-sectional study performed in patients with PCOStreated in secondary health care service by nutrition specialists.socio-demographic information, health profile, anthropometric measurements, biochemical and food intake data were obtained. The study included 54 women with an average age of 31.31 ±5.76 years: 63% were classified as obese at different levels; 74.1% presented cardiovascular risk according to waist-hip ratio, and 90.8% an increased waist circumference. Correlations between insulin resistance, measured by HOMA-IR index, and body mass index (r = 0.729, p = 0.028) were observed. Evaluation of nutritional intake revealed an insufficient amount of calories (73.6%), carbohydrates (54.7%), and micronutrients (calcium, 96.2%; iron, 98.1%). However 71.7% presented an excessive intake of lipids.There was no association between nutritional status, biochemical parameters and food intake (p> 0.05). PCOS patients present a high prevalence of obesity and nutritional inadequacies. Therefore, nutritional intervention strategies constitute important tools as a non-pharmacological treatment.

Efetividade da interveção nutricional em curto e longo prazo de pacientes com síndrome dos ovários polocísticos / Evaluate the effectiveness of short and long-term of nutritional intervention

A Síndrome dos Ovários Policísticos (SOP) é uma endocrinopatia que afeta de 6% a 10% das mulheres em idade reprodutiva. Cerca de 38 a 88% das pacientes apresentam obesidade, particularmente a visceral, que pode agravar o grau de resistência insulínica (RI) e interferir nas alterações metabólicas intrínsecas à síndrome. A redução de 5 a 10% do peso inicial pode melhorar as funções reprodutivas e metabólicas, denotando a importância de modificações nos modos de vida. Adicionalmente, o uso da metformina para a melhora da RI na síndrome com efeito sobre o peso tem sido investigado, porém os dados são inconclusivos. Objetivo: Avaliar a efetividade da intervenção nutricional em curto e longo prazo sobre o estado nutricional e consumo alimentar de portadoras de SOP em uso ou não de metformina. Métodos: Estudo de intervenção nutricional não controlado, com duração de seis meses, realizado com mulheres portadoras de SOP. As pacientes receberam plano alimentar hipocalórico (déficit 500 a 700 kcal/dia) e orientações nutricionais individualizadas. Coletaram-se dados antropométricos, alimentares - ingestão de energia, nutrientes e índice de qualidade da dieta revisado (IQD-R), informações referentes à realização de atividade física e utilização da metformina. Resultados: Iniciaram o estudo 70 mulheres, com média de idade de 30,8 ± 5,6 anos, sendo 42,9% portadoras de alguma doença ou agravo não transmissível. Destas, 95,5% apresentavam excesso de peso, 91,3% e 89,9% risco de complicações metabólicas e de doença cardiovascular avaliados por meio da circunferência da cintura (CC) e relação cintura/ quadril (RCE), respectivamente. O consumo excessivo de calorias foi observado em 35,3% da amostra. Quinze mulheres finalizaram a intervenção nutricional (180 dias), sendo essas significantes mais velhas do que as que abandonaram o estudo (33,9 ± 5,40 vs. 30,0 ± 5,45 anos; p=0,017). As demais características foram similares (p>0,05). O uso de metformina na dose de 1500mg/...

Introduction: The Polycystic Ovary Syndrome (PCOS) is an endocrinopathy that affects 6% to 10% of all childbearing aged women. Approximately 38% to 88% of the patients are obesity, especially visceral, which can increase the degree of insulin resistance (IR) and interfere with the metabolic alterations that are intrinsic to the syndrome. The reduction of 5% to 10% in the initial body weight can improve the reproductive and metabolic functions. Previous studies have been shown that the use of metformin could improve the IR with subsequent impact on body weight; however, some studies have shown inconclusive results. Aim: To evaluate the effectiveness of short and long-term of nutritional intervention in patient with POCS regarding the nutritional state and food intake considering the use or not of metformin. Methods: six-month of uncontrolled nutritional intervention were carried out on PCOS women patients who received a hypocaloric diet plan (deficit of 500 to 700 kcal/day) and individual nutritional advice. This study evaluated anthropometric and food intake data - intake of energy, nutrients and diet quality index revised, information related to the physical activity, and the use of metformin. Results: 70 women, at an average age of 30.8 ± 5.6 years, were included in the study. 42.9% of the patients presented noncommunicable diseases and injuries other than PCOS. Of all women evaluated 95.5% presented excess of body weight, while 91.3% and 89.9% presented risks of metabolic complications and cardiovascular disease, evaluated by means of waist measurement (WM) and waist/hip relation (WHR), respectively. The excessive consumption of calories could be observed in 35.3% of the sample. Fifteen women completed the nutritional intervention period (180 days). The women who finished the study presented more advanced age than those who abandoned the study (33.9 ± 5.40 vs. 30.0 ± 5.45 years; p=0.017). Other characteristics proved to be similar (p>0.05)...
