Influence of Hypovitaminosis D on the Ocurrence of Fractures / Influência da hipovitaminose D na ocorrência das fraturas

Abstract Objective To measure the levels of vitamin D in patients hospitalized for fractures and to evaluate its relationship with fractures. Methods A primary, analytical, cross-sectional, non-interventional, observational, controlled study was conducted in humans. The serum measurement of: vitamin D, parathyroid hormone (PTH), calcium, phosphorus, magnesium and albumin was performed in 49 patients who were consecutively hospitalized for surgery due to fracture(s) (study group), and in 50 patients without fractures, from the various outpatient clinics, and who underwent routine tests (control group). Results The mean level of 25-hydroxyvitaminD (25[OH]D) in patients with fractures was of 23.78 ± 8.01 ng/mL (61.22% of patients with fractures had hypovitaminosis D). The mean 25(OH)D of the control group was of 37.52 ± 9.21 ng/mL (10% of the patients had hypovitaminosis D). Most cases of hypovitaminosis (96%) did not course with secondary hyperparathyroidism (mean PTH = 41.80 ± 22.75 pg/mL). Conclusion Hypovitaminosis D was found in a significant percentage (61.22%) of the patients who suffered fractures. Further studies on the subject are needed to better understand the influence of hypovitaminosis D on the occurrence of fractures, as well as the benefits of vitamin D supplementation in these patients.

Resumo Objetivo Dosar a vitamina D nos pacientes internados por fratura e avaliar sua relação com as fraturas. Métodos Realizou-se estudo primário, analítico, transversal, não intervencional, observacional, controlado, em seres humanos. Fez-se a dosagem sérica de: vitamina D, paratormônio(PTH), cálcio, fósforo, magnésio e albumina em 49 pacientes que foram internados consecutivamente para cirurgia devido a fratura(s) (grupo de estudo), e em 50 pacientes, dos diversos ambulatórios, sem fraturas, e que realizaram exames de rotina (grupo de controle). Resultados A média de 25-hidroxivitamina D (25[OH]D) nos pacientes com fraturas foi de 23,78 ± 8,01 ng/mL (61,22% dos pacientes com fraturas apresentaram hipovitaminose D). A média de 25(OH)D do grupo de controle foi de 37,52 ± 9,21 ng/mL (10% dos pacientes apresentaram hipovitaminose D). A maioria dos casos de hipovitaminose (96%) não cursou com hiperparatireoidismo secundário (média do PTH = 41,80 ± 22,75 pg/mL). Conclusão A hipovitaminose D foi encontrada em um percentual expressivo (61,22%) dos pacientes que sofreram fraturas. Mais estudos sobre o assunto são necessários para se compreender melhor a influência da hipovitaminose D na ocorrência das fraturas e os benefícios da suplementação com vitamina D nesses pacientes.

Alteración de las vitaminas en pacientes con cáncer: un estudio comparativo prospectivo / Vitamins disturbance in cancerous patients: A prospective comparison study

Cancers are a complex diseases that involve abnormal cell growth pattern and it is the leading cause of morbidity and mortality worldwide. The chemotherapy is one of the most common treatments for cancer. Cancer cause malnutrition and deficiencies of vitamins, in addition chemotherapy causes those deficiencies by induced anorexia, stomatitis, and alimentary tract disturbances. The study aims to determined and assessed the levels of serum vitamins (A, B12, B6, B9, E, D, and K) before and after chemotherapy administration. A prospective study carried out on newly diagnosed cancerous patients whom receiving chemotherapy. Fifty patients enrolling and recruited. Follow up will be recorded after the first, third, and sixth cycles of chemotherapy. The panel used for evaluation of vitamins concentration included the following six kits: Human Vitamin AV, E, VB6, B12, VD3 DIY, VK and FOLR3 ELISA kits. 38 females and 12 males included, with mean age was 48.35±15.28 years. The mostly distributed age group was belong to fifth decades. The mean body mass index (BMI) was 33.12±5.51 m2 /Kg. The majority of the sample treated were breast cancers females about 26(52%). Regarding chemotherapy regimens, the AC+Taxen protocol was mostly used. The mean level of vitamin A found to be declined to the half from (69.23±24.66 µg/dL) at C0 to (35.73±18.89 µg/dL) at C6. Normal mean value of vitamin B12 level was presented in the most of patients pre- and post- chemotherapy. Vitamin B6 concentrations in the most of patients risen by double post-chemotherapy. Vitamin D concentration not changed in pre- and post- chemotherapy. We observed a statistically significant differences among vitamin E concentration pre- and post- chemotherapy (ANOVA=3.213, P=0.033). In this study, most of patients pre-chemotherapy period had normal folate level, whereas it to decreased from (6.23±3.12 ng/mL) to reached (3.33±2.72 ng/mL) after anti-cancer, with strong statistically significant differences (ANOVA=6.56, P=0.012). In addition, vitamin K concentration was unchanged throughout chemotherapy cycles. Many factors in cancerous participants lead to vitamins deficiencies. Several vitamins remained within normal concentration throughout anti-cancer course might be due to vitamins supplement taken by persons during their regimens. Almost always vitamins concentration dropped during cycles, but still within normal value, except vitamin E, which was deficient in last cycle of chemotherapy. Vitamins replacement are mandatory for substitution dropping level because off those are essential for many body processes and regulation.

Nutritional deficiencies in women athletes cause numerous health problems, as well as a worsening of sports performance, as a result of these nutritional deficiencies. Awareness of these deficiencies and their prevention should be a major aspect for any sports manager. The aim of the study was to establish the importance of studying the deficits of energy, protein, minerals (Fe, Ca and Mg) and vitamins (Vitamin D, folic acid and vitamin B12) that can be developed by female athletes and their relationship with the prevalence of the female triad and to establish the importance of knowledge by sports managers of the problems arising from nutritional deficiencies. 51 papers were found. A bibliographic search of relevant articles for the study objective was carried out (2013-2020). Scientific databases such as PubMed and Pennutrition were used, following the exclusion and inclusion criteria chosen for this study. The results showed the prevalence of energy, Fe, vitamin D and Ca, as well as sufficient protein intake and a lack of studies to determine the levels of vitamin B12 and folic acid. In addition, the prevalence of women meeting one or more risk factors for the development of the female sports triad was observed. It is essential the prevention or, treatment, of nutritional deficits in female athletes to ensure proper health status and optimal sports performance(AU)

Hypovitaminosis D and Calcium Intake in Adult Population / Hipovitaminosis D y la ingesta de calcio en población adulta / Hipovitaminose de ingestão de cálcio em população adulta

Abstract: Background: Daily dietary calcium intake below the requirements has been related to low levels of vitamin D (Vit-D) and osteoarticular diseases. Objective: To determine the prevalence of Vit-D deficiency in the general population living in Bogotá, its relationship to dietary calcium intake, and the influence of socio-demographic factors and sunlight exposure. Materials and methods: In a pro-spective cohort of the general population (randomly selected), excluding individuals with conditions affecting calcium absorption or adequate Vit-D action, the prevalence of hypovitaminosis D (95 % ci) and regular consumption of calcium (RCI, mg/day) is measured according to socio-demographic, anthropometric, biochemical, and sunlight exposure variables. A multiple regression model is implemented (no intercept) to predict Vit-D concentration based on the factors described. Results: Ninety-seven patients are included, 61 % of which are women, with a median age of 23 years, a weight of 65 kg (IQR: 55.2-70.5), a height of 165 cm ± 8.9, and BMI of 22.8 kg/m2 (IQR: 21.2-25.2). The RCI was 393.7 mg/day, less than the benchmark for Colombian adults (p < 0.001); serum calcium concentration was 9.7 mg/dL. The mean Vit-D concentration (95 % ci) was 23.7 ng/mL (22.6-24.7); hypovitaminosis D was identified in 87 % of the sample (80.6-94.7 %), 24.7 % were classified as poor (15.6-33.8 %) and 62.9% as insufficient (52.8-73%). Vit-D concentration was predicted in a quadratic function by the interaction between sex, sunlight exposure, and RCI (R2 > 90 %). Conclusion: The suspected high prevalence of Vit-D deficiency is confirmed in the general Colombian adult population as a result of low dietary calcium intake, demographic factors, and sunlight exposure.

Resumen: El consumo diario de calcio en la dieta por debajo de los requerimientos se ha relacionado con bajos niveles de Vitamina D (Vit-D) y con enfermedades osteoarticulares. Objetivo: Determinar la prevalencia de la deficiencia de Vit-D en la población general que vive en Bogotá, su relación con la ingesta de calcio en la dieta y la influencia de factores sociodemográficos y de la exposición a la luz solar. Materiales y métodos: En una cohorte prospectiva seleccionada aleatoriamente de la población general, excluyendo individuos con condiciones que afectaran la absorción de calcio o la acción de la Vit-D, se midió la prevalencia de hipovitaminosis D (IC 95 %) y el consumo habitual de calcio (CHC, mg/día), según variables sociodemográficas, antropométricas, bioquímicas y de exposición solar; se implementó un modelo de regresión múltiple (sin el intercepto) para predecir la concentración de Vit-D en función de los factores descritos. Resultados: Se incluyeron 97 pacientes, edad mediana 23 años, 61 % mujeres; con peso mediano 65 kg (RIC; 55,2-70,5), estatura 165 cm ± 8,9 e IMC 22,8 kg/m2 (RIC; 21,2-25,2). El CHC fue 393,7 mg/día, menor que el recomendado para adultos colombianos (p < 0,001); la concentración de calcio sérico fue 9,7 mg/dL. La concentración media (IC 95 %) de Vit-D fue 23,7 ng/mL (22,6-24,7), se identificó hipovitaminosis D en 87% (80,6-94,7%); 24,7% se clasificaron como deficientes (15,6-33,8 %) y 62,9 % como insuficientes (52,8-73 %). La concentración de Vit-D se logró predecir, en función cuadrática, por la interacción entre el sexo, la exposición solar y el CHC (R2 > 90 %). Conclusiones: Teniendo en cuenta los resultados obtenidos, se confirma la sospecha de alta prevalencia de hipovitaminosis D en población general colombiana adulta, relacionada con un bajo consumo de calcio en la dieta habitual, factores demográficos y de exposición solar.

Prevalence of hypovitaminosis D in severely obese subjects referred to bariatric surgery / Prevalência de hipovitaminose D em obesos graves encaminhados à cirurgia bariátrica

ABSTRACT: Study Design: Cross-sectional. Objective: Estimating the prevalence of hypovitaminosis D in a group of severely obese subjects referred to bariatric surgery. Methods: This study evaluated severely obese patients aged ≥18 years assisted by a specialized team in bariatric surgery. Clinical, anthropometric, and laboratory data were obtained from patient records. Plasma 25 (OH) D was determined by chemiluminescence and levels ≤ 20 ng/mL was considered as Hypovitaminosis D. The data were analyzed using the Statistical Package for Social Sciences® (SPSS) 20.0. Variables were described using descriptive statistics. For the comparison of the three groups, ANOVA, Kruskal-Wallis, and Pearson's chi-square tests were used. Spearman correlation test was performed to assess correlations between 25(OH)D and the other variables. P-values <0.05 were considered to be significant. Results: The study included 400 individuals, 71% were female with the mean age (SD) and BMI (SD) of 35.6 (9.1) years and 41.4 (5.1) kg/m², respectively. The vitamin D ranged from 4.5 to 62.4 ng/mL and the mean (SD) was 24.7 (7.9) ng/mL. In this sample, 117 (29.3%) individuals had hypovitaminosis D. There was a negative correlation between 25(OH)D and BMI (r= -0.110; p=0.028) and parathormone (r= -0.152; p=0.006) and positive correlation with serum calcium (r= 0.132; p=0.013) and phosphorus (r= 0.116; p=0.027). Conclusion: Severely obese subjects had a high prevalence of hypovitaminosis D even living in a sunny state. (AU)

Prevalencia de ingesta inadecuada de micronutrientes en la población urbana de Costa Rica / Micronutrients inadequacy in urban population of Costa Rica

La inadecuación de micronutrientes es frecuente en los países en vías de desarrollo. En Costa Rica existe poca información acerca de la ingesta de micronutrientes y del impacto de los programas de fortificación obligatoria de alimentos. El objetivo de este estudio fue evaluar la ingesta de vitaminas y minerales y el aporte de la fortificación de alimentos a la ingesta total de micronutrientes en la población urbana costarricense. Se analizó el consumo de alimentos en una muestra de la población urbana costarricense, participantes del Estudio Latinoamericano de Nutrición y Salud (ELANS). El riesgo de ingesta inadecuada se estimó según sexo y grupo de edad, utilizando el método de punto de corte del Requerimiento Medio Estimado (EAR). Para el hierro, se utilizó el método de aproximación probabilística. Más del 85% de la muestra presentó riesgo de ingesta inadecuada para vitamina E, calcio y vitamina D. Una menor prevalencia de riesgo de ingesta inadecuada se presentó para la niacina, tiamina, folatos, hierro y selenio. La fortificación de alimentos tiene un efecto notorio en la ingesta de micronutrientes, especialmente de hierro, niacina, tiamina y folatos. La ingesta de calcio, vitamina D y vitamina E es preocupantemente inadecuada, siendo las mujeres y las personas mayores de 50 años los grupos más afectados. Resulta fundamental el establecimiento de programas y políticas públicas para asegurar el cumplimiento del requerimiento establecido para los diferentes micronutrientes(AU)

Micronutrient deficiencies are still very common in developing countries. In Costa Rica there is little information on micronutrients intake and the impact of food fortification.This study aimed to determine the contribution of food fortification to the total intake, and to estimate the risk of inadequate intake of vitamins and minerals in an urban Costa Rican population. As a part of the Latin American Nutrition and Health Study, we analyzed data from a nationally representative sample of 798 urban residents from Costa Rica (15-65 years old) whom provided two 24-h dietary recalls. The prevalence of inadequate micronutrient intake was estimated according to the EAR cut-point method. Iron was analyze using the probability approach. We observed a 100% of the sample are at risk of inadequate intake of vitamin D, and similar percentages were obtained for calcium and vitamin E, ranging from 92.9 to 100% and 85.5 to 99.2% respectively. A lower risk of inadequate intake was observed for niacin, thiamin, folate, iron and selenium. Food fortificationmakes an important contribution to folate, thiamin, iron and niacin intake. Despite the efforts that have been made to ensure adequate micronutrient intake in Costa Rica, the intake of calcium, vitamin D and vitamin E is still very low, especially among women and people over 50 are the most affected. Based on the above, it is recommended to promote a healthy diet through nutritional education as part of public health policies, in order to facilitates compliance to nutritional requirement(AU)

Recomendaciones de micronutrientes para grupos vulnerables en contexto de desnutrición, durante la pandemia de COVID-19 en Latinoamérica / Micronutrient recommendations for vulnerable groups in context of undernutrition, during the COVID-19 pandemic in Latin America

La crisis por COVID-19 (SARS-CoV-2) puede convertirse en una catástrofe alimentaria para Latinoamérica, aumentando las personas que padecen hambre de 135 a 265 millones, especialmente en Venezuela, Guatemala, Honduras, Haití y El Salvador, que ya enfrentaban crisis económicas y sanitarias. Este manuscrito presenta la posición de un grupo de expertos latinoamericanos sobre las recomendaciones de consumo y/o suplementación con vitamina A, C, D, zinc, hierro, folatos y micronutrientes múltiples, en contextos de desnutrición, para grupos vulnerables: mujeres embarazadas y lactantes, niñas y niños menores de 5 años y adultos mayores. Las recomendaciones buscan disminuir el impacto potencial que tendrá COVID-19 en el estado nutricional, durante la pandemia. La posición surge de la discusión de dichos expertos con base a la revisión de evidencia científica actual para estos grupos vulnerables. Está dirigida a tomadores de decisiones, encargados de políticas públicas, personal de salud y organismos de la sociedad civil. Después de la lactancia materna y una dieta suficiente en cantidad y calidad, la suplementación con los micronutrientes presentados, puede contribuir a prevenir y tratar enfermedades virales, reforzar el sistema inmune y reducir complicaciones. La lactancia materna con medidas de higiene respiratoria, el suministro de múltiples micronutrientes en polvo para niños desde los 6 meses hasta los 5 años y el aporte de hierro y folatos o micronutrientes múltiples para la embarazada, son estrategias comprobadas y eficaces que deben seguirse implementando en tiempos de COVID-19. Para los adultos mayores la suplementación con vitamina C, D y zinc puede estar indicada(AU)

The COVID-19 crisis (SARS-CoV-2) might transform into a food catastrophe in Latin America and would increase the number of people suffering from hunger from 135 to 265 million, particularly in Venezuela, Guatemala, Honduras, Haiti and El Salvador, already facing economic and health crises. This manuscript presents the position of a group of Latin American experts in nutrition for establishing the recommendations for consumption and / or supplementation with vitamin A, C, D, zinc, iron, folates and multiple micronutrients, in undernutrition contexts, for vulnerable population of pregnant and lactating women, children under 5 years and the elderly. The recommendations seek to decrease the potential impact that COVID-19 will have on nutritional status during the pandemic. The position arises from the discussion of the experts based on the review of current scientific evidence for these vulnerable groups. It aims to reach stakeholders, public policy makers, health personnel and civil society organizations. Only after breastfeeding and a sufficient diet in terms of quantity and quality, a supplementation with the micronutrients mentioned above can help prevent and treat viral diseases, strengthen the immune system and even reduce complications. Breastfeeding with respiratory hygiene measures, the provision of multiple micronutrients powders for children from 6 moths to 5 years of age and the supply of iron and folates or multiple micronutrients tablets for pregnant women are proven and effective strategies that must continue to be implemented during COVID-19 pandemic. For older adults, supplementation with vitamin C, D and zinc might be indicated(AU)

Relación entre niveles de vitamina D y perfil lipídico en embarazadas de alto riesgo / Relationship between level of vitamin D and lipid profile in high risk pregnant women

En la Argentina, las embarazadas presentan alta prevalencia (80%) de hipovitaminosis D y de sobrepeso u obesidad (27,4%). Ambas condiciones pueden aumentar la morbimortalidad materno-fetal. Bajos niveles de vitamina D se han relacionado con aumento del colesterol total, LDL, triglicéridos (Tg) y descenso de HDL. Objetivo: evaluar los niveles de 25-hidroxivitamina D (25OHD) y su relación con el perfil lipídico en pacientes embarazadas de alto riesgo. Materiales y métodos: estudio de corte transversal entre septiembre de 2016 y abril de 2017. Se excluyeron pacientes que recibieron suplementos de vitamina D, con disfunción tiroidea no compensada, malabsorción, insuficiencia cardíaca, renal o hepática y dislipidemia familiar. Niveles circulantes de 25OHD < 30 ng/ml se consideraron hipovitaminosis. Resultados: se evaluaron 86 embarazadas de 29,3 ± 7,1 años durante la semana 28 ± 6,5. El IMC pregestacional fue 28,3 ± 6,5 kg/m2 y la ganancia de peso 7 ± 4,3 kg. Perfil lipídico: colesterol total 240 ± 54 mg/dl; LDL 156 ± 54 mg/dl; HDL 66 ± 15 mg/dl; Tg 204 ± 80 mg/dl. La media de 25OHD fue de 23,8 ± 9 ng/ml, con una prevalencia de hipovitaminosis D de 77,9 %. Las pacientes con hipovitaminosis D presentaron mayores valores de colesterol total y LDL (p < 0,05), con tendencia no significativa a presentar mayores valores de Tg. Conclusión: en embarazadas de alto riesgo se observó una alta prevalencia de hipovitaminosis D, asociada con mayores concentraciones de colesterol total y LDL. (AU)

In Argentina, pregnant women have a high prevalence (80 %) of hypovitaminosis D and verweight/obesity (27.4%), conditions that can increase maternal-fetal morbidity and mortality. Low levels of 25-hydroxyvitamin D (25OHD) have been linked to an increase in total cholesterol, LDL cholesterol, triglycerides (TG) and a decrease in HDL cholesterol. Objective: to evaluate the levels of vitamin D and its relationship with the lipid profile in high risk pregnant patients. Materials and methods: cross-sectional study between September 2016 and April 2017. Patients who received vitamin D supplements or had non-compensated thyroid dysfunction, malabsorption, heart failure, renal or hepatic failure, or familial dyslipidemia were excluded. Hypovitaminosis D was defined as a circulating level of 25OHD < 30 ng/ml. Results: We assessed 86 women of 29.3 ± 7.1 years during pregnancy week 28 ± 6.5. Pre-gestational BMI was 28.3 ± 6.5 kg/m2. Their weight gain was 7 ± 4.3 kg. Lipid profile: total cholesterol 240 ± 54 mg/dl; LDL cholesterol 156 ± 54 mg/dl; HDL cholesterol 66 ± 15 mg/dL; TG 204 ± 80 mg/dl. The mean 25OHD level was 23.8 ± 9 ng/ml, with a 77.9 % prevalence of hypovitaminosis D. Patients with hypovitaminosis D had higher values of total cholesterol and LDL cholesterol (p<0.05), and a non-significant trend toward higher triglyceridemia. Conclusion: A high prevalence of hypovitaminosis D, associated with high total and LDL cholesterol was found in high risk pregnant women. (AU)

Increased Left Atrial Volume and Its Relationship to Vitamin D in Primary Care

The study is based on the fact that left atrial (LA) volume measurement is a marker of the presence of diastolic dysfunction and that Vitamin D deficiency may be associated with ventricular remodeling, worsening of left ventricular (LV) diastolic and systolic function, and activation of the renin-angiotensin-aldosterone system. Objective: To evaluate whether LAV changes are related to vitamin D deficiency. Method: A cross-sectional, population-based, unicentric study in which 640 patients over 45 years of age enrolled in the Niterói's Médico de Família program, RJ, were evaluated. Patients were submitted to tissue Doppler echocardiography to evaluate the parameters of diastolic and systolic function and vitamin D dosage. The presence or absence of hypovitaminosis D associated with structural and functional cardiac changes was compared between each group. A p < 0.05 value was considered as an indicator of statistical significance. Results: Of the 640 individuals analyzed, hypovitaminosis D was confirmed in 39.2% of the patients, of whom 34.8% had diastolic dysfunction. The most relevant echocardiographic parameters that were statistically significant were non-indexed AEDs and LAV, E'/A' and E wave deceleration time, which were associated with the presence of hypovitaminosis D (P < 0.01). Conclusion: The study of the association of hypovitaminosis D and the appearance of structural and functional cardiac abnormalities may contribute to the discussion of the adoption of one more criterion to select individuals at risk of developing clinical cardiac insufficiency in primary care since, with the use of echocardiography, the subclinical condition of cardiac involvement, with prognostic and treatment implications for the referred patients with hypovitaminosis D, can be identified early

Severe malnutrition after bariatric surgery and clinic manifestations of infection

SUMMARY This report describes the post-bariatric-surgery evolution of an obese patient who had low adherence to the diet and micronutrient supplementation. Four years after two bariatric surgeries, the patient was admitted due to transient loss of consciousness, slow thinking, anasarca, severe hypoalbuminemia, in addition to vitamin and mineral deficiencies. She had subcutaneous foot abscess but did not present fever. Received antibiotics, vitamins A, D, B12, thiamine, calcium, and parenteral nutrition. After hospitalization (twenty-eight days), there was a significant body weight reduction probably due to the disappearance of clinical anasarca. Parenteral nutrition was suspended after twenty-five days, and the oral diet was kept fractional. After hospitalization (weekly outpatient care), there was a gradual laboratory data improvement, which was now close to the reference values. Such outcome shows the need for specialized care in preventing and treating nutritional complications after bariatric surgeries as well as clinical manifestations of infection in previously undernourished patients.

RESUMO Este relato descreve a evolução pós-cirurgia bariátrica de uma paciente obesa que apresentou baixa adesão à dieta e suplementação de micronutrientes. Quatro anos após duas cirurgias bariátricas, a paciente foi internada por perda transitória de consciência, raciocínio lento, anasarca, hipoalbuminemia grave, além de deficiências vitamínicas e minerais. Apresentava abscesso subcutâneo no pé, mas não apresentava febre. Recebeu antibióticos, vitaminas A, D, B12, tiamina, cálcio e nutrição parenteral. Após a internação (28 dias) houve redução significativa do peso corporal, provavelmente devido ao desaparecimento clínico da anasarca. A nutrição parenteral foi suspensa após 25 dias e a dieta oral foi mantida fracionada. Após a internação (atendimento ambulatorial semanal) houve uma melhora gradativa dos dados laboratoriais, que estavam próximos dos valores de referência. Tal desfecho mostra a necessidade de cuidados especializados na prevenção e tratamento de complicações nutricionais após cirurgias bariátricas, bem como manifestações clínicas de infecção em pacientes previamente desnutridos.

El hambre oculta y la fibromialgia: Una revisión sistemática / The hidden hunger and fibromyalgia: A systematic review

RESUMEN Recientemente há sido discutida la posibilidad de una relación causal entre la fibromialgia (FM) y la deficiencia de micronutrientes, un tipo de deficiencia nutricional conocida como "hambre oculta". Sin embargo, los estudios son pocos y los resultados controversiales, lo que genera debates sobre la influencia real del "hambre oculta" en el proceso de la enfermedad en las personas con fibromialgia. En está revisión se presentan y discuten evidencias científicas relacionadas con la deficiencia de micronutrientes y FM, destacando los principales micronutrientes relacionados. El levantamiento de información fue realizado en los bases de datos de PubMed y Science Direct en estudios observacionales publicados entre los años 2000 y 2017. Fueron seleccionados 14 estudios, ocho dirigidos a la asociación de la deficiencia de vitamina D y la presencia de FM y seis enfocados en la asociación de la deficiencia de minerales con FM. Se sugiere una relación entre la deficiencia de vitamina D y el aumento de la sensibilidad al dolor en la FM. Aunque esa insuficiencia también está asociada a otras enfermedades muscoesqueléticas crónicas. Además, parece que la deficiencia mineral (p.ej.o., hierro, magnesio, zinc y calcio) también desempeña un papel importante en el inicio de la FM y sus principales síntomas.

ABSTRACT Recently the possibility of a causal link between fibromyalgia (FM) and micronutrient deficiency, a type of malnutrition known as "hidden hunger", has been suggested. However, the results are controversial, which raises questions and debates on the actual influence of "hidden hunger" on the development of FM. In this review, we present and discuss scientific evidence related to micronutrient deficiencies and FM, highlighting key micronutrients involved. We searched PubMed and Science Direct databases for all observational studies published between 2000 to March 2017. We selected fourteen observational studies, eight studies aimed at linking vitamin D deficiency to the presence of FM and six studies focused on the association of mineral deficiency with FM. The association between vitamin D deficiency and increased pain sensitivity in FM is suggested, although such insufficiency is also associated with other chronic musculoskeletal disorders. It appears that mineral deficiency (e.g., iron, magnesium, manganese, zinc and calcium) plays an important role in the onset of FM and its main symptoms.

Hypovitaminosis D in pregnancy: Is it a public health issue? / Hipovitaminose D na gestação: um problema de saúde pública?

Abstract Objectives: to measure the prevalence of hypovitaminosis D in healthy pregnant women and to analyze the association among some variables and the levels of vitamin D. Methods: an analytical cross-sectional study. 174 healthy pregnant women were selected from four basic health units in São Luís, Brazil, from January to February 2017. The participants answered a questionnaire about sociodemographic and obstetric data. A blood sample was collected to evaluate the plasmatic level of vitamin D. The association between independent variables and the outcome was evaluated by using the Student's t-test and Chisquare test. Results: the mean of vitamin D concentration was 24.9±6.6ng/ml. Forty women (23.0%) presented vitamin D sufficiency, 93 (53.4%) insufficient, and 41 (23.6%) with deficiency. There was a difference in the vitamin D concentration between evangelical (23.1 ng/ml) and non-evangelical (25.5 ng/ml) (p=0.02) and between primigravida (23.8 ng/ml) and non-primigravida (25.7 ng/ml) (p=0.03). There was a difference in the hypovitaminosis D between adolescents (89.7%) and non-adolescents (72.6%) (p=0.02) and between primigravida (85.0%) and non-primigravida (69.2%) (p=0.01). Low monthly income per capita was associated with a higher frequency of vitamin D sufficiency. Conclusions: Due to the impact of inadequate levels of vitamin D in pregnant women and their babies' health, even in an equatorial city, hypovitaminosis D in pregnant women is an important public health issue.

Resumo Objetivos: medir a prevalência de hipovitaminose D em gestantes saudáveis e analisar a associação entre variáveis e níveis de vitamina D. Métodos: estudo analítico transversal. 174 gestantes saudáveis selecionadas em quatro unidades básicas de saúde em São Luís, Brasil, em janeiro/fevereiro/2017. As participantes responderam um questionário contendo dados sociodemográficos e obstétricos. Coletou-se uma amostra de sangue para avaliar o nível plasmático de vitamina D. A associação entre as variáveis independentes e o desfecho foi avaliada pelos testes t de Student e Qui-quadrado. Resultados: a concentração média de vitamina D foi de 24,9±6,6 ng/mL. Quarenta mulheres (23,0%) apresentaram suficiência de vitamina D, 93 (53,4%) insuficiência, e 41 (23,6%) deficiência. Houve diferença na concentração de vitamina D entre evangélicas (23,1 ng/mL) e não-evangélicas (25,5 ng/mL) (p=0,02), e entre primigrávidas (23,8 ng/mL) e não-primigrávidas (25,7ng/mL) (p=0,03). Houve diferença na hipovitaminose D entre adolescentes (89,7%) e não-adolescentes (72,6%) (p=0,02) e entre primigrávidas (85,0%) e não-primigrávidas (69,2%) (p=0,01). Menor renda mensal per capita associou-se a uma maior frequência de suficiência de vitamina D. Conclusões: Devido ao impacto dos níveis inadequados de vitamina D na saúde das gestantes e dos seus recém-nascidos, mesmo em uma cidade equatorial, a hipovitaminose D em gestantes é um importante problema de saúde pública.

Influencia de la estación del año en los niveles de vitamina D de una población pediátrica / Influence of the season of the year in vitamin D levels in a pediatric population

Introducción: El objetivo de nuestro trabajo es determinar los niveles séricos de 25 (OH) vitamina D en una población pediátrica de la Ciudad de Rosario y sus alrededores y la influencia de las diferentes estaciones del año sobrelos mismos.Material y métodos: Estudio prospectivo observacional en el que se dosó el nivel de vitamina D en niños de ambossexos menores de 15 años de edad. El plazo de medición fue de un año calendario para posteriormente y analizarsus niveles según las cuatro estaciones del año. Todos los análisis de vitamina D fueron realizados por el mismolaboratorio y el mismo equipo de medición.Resultados: Se incluyeron 128 pacientes de ambos sexos. Del total de mediciones se encontraron niveles inferioresa 30 ng/ml en el 61,7% (n=79). Las medias de los niveles de Vitamina D fueron en otoño 32,6 ng/ml (±12,3);invierno 24,4 ng/ml (±8,7); primavera 24,1 ng/ml (±7,2) y en verano 27,8 ng/ml (±10,8). Existieron diferenciassignificativas entre las estaciones de otoño y primavera (p< 0,001) y entre otoño e invierno (p<0,004). Otoño fue laúnica estación que presentó niveles superiores a 30 ng/ml (media: 32,6).Conclusiones: Existe una alta prevalencia de niveles bajos de vitamina D (según lo publicado en la literatura a nivelinternacional). Recomendamos su dosaje especialmente en las estaciones de invierno, primavera y verano (AU)

Introduction: The purpose of our work is to determine the serum levels of 25 (OH) vitamin D in a pediatric populationof the City of Rosario and surrounding areas, and the influence of the different seasons of the year on them.Material and methods: A prospective observational study in which the level of vitamin D was measured in children ofboth sexes under 15 years of age. The measurement period was one calendar year to be subsequently analyzed accordingto the four seasons of the year. All vitamin D tests were performed by the same laboratory and the same measurementequipment. Results: 128 patients of both sexes were included. Of the total measurements, levels lower than 30 ng / ml were found in61.7% (n = 79). The averages of Vitamin D levels were: in autumn 32.6 ng / ml (±12,3); winter 24.4 ng / ml (±8,7);spring 24.1 ng / ml (±7,2) and summer 27.8 ng / ml (±10,8). There were significant differences between the autumn andspring seasons (p <0.001) and between autumn and winter (p <0.004). Autumn was the only station that presented levelshigher than 30 ng / ml (mean: 32.6).Conclusions: There is a high prevalence of low levels of vitamin D (as published in the international literature). We recommend its dosing especially in the winter, spring and summer seasons (AU)

Prevalence of low folate deficiency after wheat flour supplementation - should we still measure serum folate?

ABSTRACT Objectives: To determine the frequency of folic acid deficiency in consecutive serum folate determinations and to determine whether there was a significant decrease in serum folate deficiency after folate was added to wheat flour. Methods: A retrospective descriptive observational study was performed of consecutive folate measurements at the Hospital Privado Universitario, Cordoba, Argentina. Results: Two cohorts were analyzed: 1197 folate measurements between 2001 and 2008 (before supplementation) and 3335 folate measurements from 2009 to 2014 (after supplementation). Folate deficiency was found in 84/1197 (7%) subjects in the pre-supplementation group and in 58/3335 (1.73%) after supplementation. The prevalence of folate deficiency was 12% between 2001 and 2003 when folate was not added to flour compared to 4% in 2004-2007 (p-value < 0.0001) when folate was added to the flour but no widespread use was documented. Conclusions: In the studied population, the prevalence of serum folic acid deficiency after folate supplementation was low at 1.73%. There was a significant decrease in folate deficiency after folate was added to wheat flour. Given the low prevalence of folic acid deficiency observed in this and similar studies, and the observed change with supplementation, we conclude that routine measurement of serum folate is of limited clinical use.

Deficiência da Vitamina D e doenças cardiovasculares / Vitamin D deficiency and cardiovascular diseases

A vitamina D é considerada um hormônio esteroide com amplo espectro de atuação no organismo humano. Sua ação ocorre a partir da ligação do seu metabólito ativo (1α, 25-di-hidroxivitamina D) com seu receptor (VDR) que se encontra presente em todo o organismo, inclusive nas células musculares lisas vasculares e nos cardiomiócitos. Inicialmente, a deficiência de vitamina D havia sido relacionada apenas com alterações no sistema musculoesquelético. Porém, nos últimos anos, pesquisadores têm demonstrado sua relação com diversas patologias pertencentes a outros sistemas, tais como as doenças cardiovasculares. O objetivo deste trabalho foi revisar a fisiopatologia da vitamina D, descrever sua relação com as doenças cardiovasculares com base nas publicações mais recentes e destacar os resultados da suplementação vitamínica na prevenção de tais patologias
