ABSTRACT

Bachkgrond: Anemia is a very important nutritional disorder in the world, it has multiple etiologies and pregnancy is associated with a deficit in the intake of iron and physiological changes of pregnancy. Aim of the study: To assess the prevalence of anemia in pregnant Iraqi women. Patients and method: A cross-sectional study carried at Al-Elwyia maternity teaching hospital in the period from the 1st of Jan. 2018 to the end of October 2018, in which 1000 pregnant women were enrolled in the study and divided into 2 groups: case group (n=652) and control group (n=348) according to the level of Hb. Results: The mean age of the case group was (27.8±7.1) years old and (26.1±2.3) years for the control group. The anemia was found in (6521000) patients and Iron deficiency anemia is the main type of anemia (80.2%) while (19.8%) was another type of anemia. Poor diet (65%) is the common cause of anemia were found commonly in the 3rd trimester (50.2%). Conclusion: The prevalence of anemia was 65.2% in the current study (AU)

ABSTRACT

RESUMO Objetivo: comparar a prevalência das deficiências de micronutrientes nos pacientes submetidos à gastrectomia vertical (GV) e à derivação gástrica em Y de Roux (DGYR). Métodos: estudo comparativo de 576 pacientes submetidos à cirurgia bariátrica, 338 através de GV e 238 de DGYR e avaliados quanto às dosagens séricas de hemoglobina, ferro, ferritina, zinco e vitamina B12. Estas dosagens foram realizadas nos períodos pré-operatório e três, seis, 12 e 24 meses após a cirurgia, para análise e comparação das deficiências de micronutrientes entre as técnicas. Resultados: o grupo submetido à GV foi composto por 48 homens e 290 mulheres, com IMC médio de 39,4±2,6Kg/m2 e média de idade de 37,2±11 anos; o grupo submetido à DGYR foi composto por 77 homens e 161 mulheres, com IMC médio de 42,7±5,9Kg/m2 e média de idade de 41,9±11,1 anos. Após 24 meses, déficit de hemoglobina se fez presente em 24,4% dos pacientes submetidos à GV e 40% da DGYR (p=0,054); deficiência de ferro em 6,6% da GV e 15% da DGYR (p=0,127); déficit de ferritina em 17,8% da GV e 23,7% da DGYR (p=0,399); deficiência de zinco em 6,6% da GV e 30% da DGYR (p=0,002) e deficiência de B12 em 6,6% da GV e 8,7% da DGYR (p=0,844). Conclusão: pacientes submetidos à GV apresentaram níveis séricos de ferro e zinco superiores aos pacientes submetidos à DGYR, e a prevalência de déficit deste último micronutriente foi significativamente maior no grupo da DGYR.


ABSTRACT Objective: to compare the prevalence of micronutrient deficiencies in patients submitted to sleeve gastrectomy (SG) and Roux- en-Y gastric bypass (RYGB). Methods: this is a comparative study of 576 patients submitted to bariatric surgery, 338 to SG and 238 to RYGB, and evaluated for hemoglobin, iron, ferritin, zinc and vitamin B12 serum levels. We performed these dosages in the preoperative period and at three, six, 12 and 24 months after surgery, for analysis and comparison of micronutrient deficiencies among the techniques. Results: the SG group consisted of 48 men and 290 women, with a mean BMI of 39.4±2.6kg/m2, and a mean of age of 37.2±11 years; the group RYGB consisted of 77 men and 161 women, with mean BMI 42.7±5.9kg/m2, and a mean age of 41.9±11.1 years. After 24 months, hemoglobin deficiency was present in 24.4% of the patients submitted to SG and in 40% of the RYGB individuals (p=0.054); iron deficiency was present in 6,6% of SG patients and in 15% of RYGB ones (p=0.127); ferritin deficiency occurred in 17.8% of the SG group and in 23.7% of RYGB one (p=0.399); the Zinc deficiency incidence was 6.6% in SG and 30% in RYGB (p=0.002); and B12 deficiency took place in 6.6% the SG patients and in 8.7% of RYGB ones (p=0.844). Conclusion: patients undergoing SG had serum levels of iron and zinc superior to the ones undergoing RYGB, the prevalence of the latter micronutrient deficit being significantly higher in the RYGB group.

ABSTRACT

Introdução: No Brasil, a anemia por deficiência de ferro permanece como problema de saúde pública relevante, especialmente para mulheres e crianças. Nessa questão, a situação de insegurança alimentar (IA) pode vir a ser associada a diversos aspectos de desigualdades estruturais e em saúde, visto que seu conceito permite abordar diversos tipos de iniquidades nutricionais. Objetivos: Avaliar a anemia e a insegurança alimentar e nutricional de famílias de crianças em idade pré-escolar: analisar a influência da vulnerabilidade socioeconômica sobre a prevalência da anemia; identificar os padrões alimentares e sua relação com segurança alimentar e estado nutricional; e investigar a relação entre insegurança alimentar e concentração de hemoglobina de pré-escolares. Métodos: A pesquisa foi do tipo transversal. A população investigada foi de pré-escolares inscritos em creches públicas de Taubaté (SP), em 2014, distribuídas em dois grupos diferenciados pelas características socioeconômicas da região onde estão localizadas: região vulnerável e região abastada. O tamanho da amostra foi calculado partindo do pressuposto que a diferença na concentração de hemoglobina (Hb) entre crianças da região vulnerável e abastada fosse equivalente a 1/3 de desvio padrão da média de Hb da população saudável. As variáveis socioeconômicas e demográficas foram coletadas por questionário semi-estruturado. A concentração de Hb foi obtida por meio de punção digital, considerando anemia Hb


Introduction: In Brazil, iron deficiency anemia remains a relevant public health problem, specially for women and children. In this respect, the situation of food insecurity (FI) may prove to be associated with various aspects of structural inequalities and health, as its concept allows addressing various types of nutritional inequities. Objective: Evaluate anemia, food and nutrition insecurity of families of children in preschool age; analyze the influence of socioeconomic vulnerability on the prevalence of anemia; identify dietary patterns and their relation to food security and nutritional status; and investigate the relationship between food insecurity and concentration of preschool hemoglobin. Methods: The study was crosssectional. The investigated population was enrolled preschool children in public day care centers in Taubaté (SP) in 2014, divided into two different groups by socioeconomic characteristics of the region where they are located: vulnerable region and wealthy region. The sample size was calculated on the assumption that the difference in hemoglobin (Hb) between children of vulnerable and wealthy region was equivalent to 1/3 of Hb mean standard deviation of the healthy population. Socioeconomic and demographic variables were collected by semi-structured questionnaire. The Hb concentration was obtained by finger prick, considering anemia Hb

ABSTRACT

A presença de anastomoses vasculares placentárias nas gestações gemelares monocoriônicas favorece o surgimento de complicações graves como a Síndrome de Transfusão Feto-Fetal (STFF) e a Sequência Anemia-Policitemia em Gêmeos (TAPS). STFF e TAPS são ambas formas crônicas de transfusão feto-fetal. TAPS, descrita em 2007, é caracterizada por anemia crônica no gêmeo doador e policitemia no gêmeo receptor, na ausência de discordância no volume de líquido amniótico, característica da STFF clássica. O diagnóstico pode ser feito pré- e pós-natal. O critério diagnóstico pré-natal é baseado na discordância intergemelar da medida do Doppler do pico de velocidade sistólica da artéria cerebral média (PSV-ACM). O diagnóstico pós-natal é baseado na grande diferença da hemoglobina intergemelar, ao nascimento, e reticulocitose no gêmeo doador.(AU)


The presence of placental vascular anastomoses in monochorionic twins favors the development of several complications like Twin-Twin Transfusion Syndrome (TTTS) and Twin Anemia-Polycythemia Sequence (TAPS). TTTS and TAPS are both chronic forms of fetofetal transfusion. TAPS, described on 2007, is characterized by chronic anemia in the donor twin and polycythemia in the recipient twin, in the absence of amniotic fluid volume discordances, characteristic of classical TTTS. The diagnostic can be made pree posnatally. The prenatal diagnostic criteria is based on the inter-twin discordance in Doppler measurement of peak systolic velocity in the middle cerebral artery (MCA-PSV). The postnatal diagnosis is based on large intertwin hemoglobin difference at birth and retoculocytosis in the donor twin.(AU)

ABSTRACT

El presente estudio buscó analizar la asociación entre la (in)seguridad alimentaria y el estado nutricional de niños preescolares asistidos en jardines infantiles. La seguridad alimentaria fue evaluada a través de la Escala Brasileña de Inseguridad Alimentaria (EBIA). El estado nutricional se evaluó a través del peso/edad, talla/edad, hemoglobina, retinol sérico y zinc sérico. Fueron encontradas prevalencias de déficit de estatura (6,2%), déficit de peso/edad (2,1%), deficiencia de vitamina A (24,4%), anemia (15,5%) y deficiencia de zinc (15,0%). La inseguridad alimentaria familiar fue caracterizada en 64,2% de las familias predominando la forma leve (32,6%). El estudio concluye que la inseguridad alimentaria estimada por la EBIA no se asoció a los Escore-z de crecimiento ni a las concentraciones de retinol sérico, hemoglobina y zinc sérico.


This study sought to examine the association between the food (in)security and nutritional status of preschool children attended in daycare centers. Food security was assessed using the Brazilian Food Insecurity Scale. The nutritional status was evaluated using the weight/height, weight/age, height/age, hemoglobin, serum retinol and serum zinc status. The prevalence of stunting (6.2%), overweight (3.1%), underweight (2.1%), vitamin A deficiency (24.4%), anemia (15.5%), and zinc deficiency (15%) was established. Food insecurity was found in 64.4% of the families, predominantly in its mild form (32.6%). This study concludes that food insecurity as measured by the EBIA was not associated with Z-score growth or with vitamin A, hemoglobin and zinc biochemical concentrations.

ABSTRACT

Introduction: Anemia is common problem in people of high socioeconomic status of all age group. Th is is usually seen with reduced work capacity, early fatigability, mental irritation, dyspnea etc. Despite of good and easy availability of food, young girls of high socioeconomic status still remain anemic mainly due to lack of self care in terms of nutritional diet, somewhat hate for green leafy vegetables, charm of junk foods devoid of nutritional substances including iron, inadequate physical exercise. Present study was conducted to assess the pulmonary functions in young anemic female medical students belonging to high socioeconomic status. Methods: Based on Hemoglobin level subjects were divided in to 2 groups. Group 1 comprised of obese students (Hb>12 gm/dl) and group 2 comprised of anemic students (Hb<12gm/dl). Age, height and weight, of all subjects were noted. Body mass index was calculated by dividing weight (in Kg) with height in meter2. Data obtained were analyzed using t-test. Result: Forced Vital Capacity (FVC), Peak expiratory fl ow rate (PEFR), FEV1 and Maximum voluntary ventilation (MVV) in anemic group subjects were signifi cantly lower in comparison to control group. However FEV1/FVC did not show any signifi cant diff erence. Conclusion: Anemia leads to decreased pulmonary functions which further hampers the oxygenation of the tissue and may worsen the physical and mental capabilities.

ABSTRACT

The group of pregnant women is one of the most sensitive to anemia and they have the deleterious consequences resulting therefrom. This research aims to demonstrate the importance of making during the prenatal examinations required including complete blood count, along with the kinetics of iron. In normal pregnancy there is expansion of plasma volume of up to 40-60% and red cell mass of 20-40%, with the sixth to seventh month. Pan American Health indicate that 42% of pregnant women in Brazil would be anemic. Usually pregnant women anemia is caused by increased demand for iron, and the strategy to combat iron deficiency and iron deficiency anemia is well established, consisting briefly on the following: change in eating habits, diagnosis and treatment of causes of loss blood, infection control that contribute to anemia, food fortification and supplementation with iron salts. This study aims to evaluate the management of pregnant women with low hemoglobin in the basic health unit investigated, and verify the effectiveness of the procedures adopted by that institution to reverse the above mentioned. This was a cross-sectional study with secondary data. The data showed that the prevalence of anemia increased the hemoglobin concentration decreased with the evolution of pregnancy.

ABSTRACT

To describe and quantify the functional change of the lung in patients with beta-thalassemia major [TM] and determine the correlation between pulmonary function test [PFT] results with hemoglobin, ferritin and age changes. Pulmonary function tests were performed on 60 transfusion-dependent patients with TM, ranging in age from 10 to 45 years. Percent-predicted values for forced expiratory volume in one second [FEV1], and forced expiratory flows [FEF] 25-75% were significantly reduced, whereas forced expiratory vital capacity [FVC] and FEV1/FVC were closed to normal limits, indicating a restrictive disease. All factors including; FVC, FEV1, and FEV1/FVC, FEF 25-75% were negatively correlated with age and ferritin levels. In contrast, all factors including; FVC, FEV1, and FEV1/FVC, FEF 25-75% were positively correlated with hemoglobin [Hb]. We performed linear regression analysis to study the simultaneous influence of the presence of age, ferritin, and Hb on obstructive PFT indexes. Pulmonary function test results were normal in only 32 [53.3%] of 60 patients and the rest 28 cases [46.7%] showed abnormal pulmonary function. FEV1 and FEF25%-75% have significant negative correlation with age [r=- 0.64 p[r]=0.003 and r=- 0.58 p[r]=0.02 respectively], also have significant positive correlation with Hb [r=0.31 p[r]=0.015 and r=0.33 p[r]=0.01 respectively], and only FEF25%-75% has significant negative correlation with ferritin [r=-0.26 p[r]=0.04]. The present study has shown that restrictive disease and reduced lung diffusing capacity are the predominant abnormalities of pulmonary function in patients with TM. The low hemoglobin concentration and a fall in the diffusing capacity of the alveolar-capillary membrane, together with the dependence of the reduced pulmonary diffusing capacity on age and serum ferritin levels, as well as of the entity of restrictive disease on age, suggests that pulmonary dysfunctions in patients with TM are due mainly to lung fibrosis and/or interstitial edema related to iron overload

ABSTRACT

Anemia is the most frequent complication of chronic renal failure. Epoetin therapy reveals to be an effective therapy; however, development of anti-erythropoietin antibodies has been reported. The present study was conducted to determine the etiology of refractory anemia after Epoetin therapy in patients with chronic renal failure. All adult patients [530 patients] who had been prescribed regular hemodialysis and rHUEPO for at least three months were followed in seven hemodialysis units in Tehran. During a 6- month period, Venofer-Eprex dose and hemoglobin was recorded monthly. Having ruled out hemolysis and iron deficiently state in severe anemic patients, bone marrow examination was ordered. Of 530 patients, 58% were men with median age of 59 years. About%80 of patients had received baseline dose of at least 4000 units Eprex per week, prescribed subcutaneously after hemodialysis. Approximately, 21% were not anemic, while 19% did suffer from severe anemia [Hb<8]. There were statistically significant associations between severity of anemia and age [p<0.001], longer Epoetin therapy [p<0.001], co-treatment with Venofer [p<0.011] and lack of underlying disease [p<0.04]. Bone marrow aspiration was performed for 30 patients and the most frequent findings were anemia due to chronic disease, bone marrow dysplasia, amd megaloblastic anemia. In case of poor response to Epoetin therapy, discontinuing the drug is strongly recommended. Bone marrow examination is an appropriate tool to find the cause of refractoriness to Epoetin therapy in hemodialysis patients

ABSTRACT

Objetivo: Estimar a concentração de hemoglobina [Hb], a prevalência de anemia e investigar os fatores de risco associados, em lactentes <12meses atendidos em serviços públicos da rede básica de saúde. Métodos: Estudo transversal, com 5967 crianças <12meses, em acompanhamento pediátrico de rotina, 12 cidades nas 5 regiões brasileiras. Os dados da criança foram copiados das fichas de acompanhamento, a dosagem de Hb foi feita com fotômetro portátil (HemoCue) e a prática alimentar foi obtida pelo processo current status. Foram construídas curvas de [Hb] e comparadas às de outros pesquisadores. As crianças <6meses foram avaliadas segundo nível de [Hb] e as com 6 meses e mais conforme existência de anemia, sendo consideradas anêmicas as crianças com nível de Hb < 11g/dL (OMS). Foram analisados os fatores de risco para [Hb] e anemia, segundo técnica de regressão múltipla utilizando-se modelo com seleção hierárquica. Utilizou-se os programas estatísticos Stata 8 e Epi Info 6.0. Resultados: As [Hb] médias foram inferiores a 1g/dl em todas as regiões do país. A região Centro-Oeste apresentou maior proporção de [Hb] >11g/dL e a região Norte a menor. Foi encontrada concentração média de Hb>11g/dL somente nos dois primeiros meses de vida. A média de prevalência de anemia foi 65,4 por cento. Foi verificada a associação entre: [Hb] e regiões, tempo de gestação, peso ao nascer, Ter sido amamentado, consumo de alimentos fonte de ferro e idade; anemia e regiões, idade materna, peso ao nascer, situação atual de aleitamento, consumo de alimentos fonte de ferro e sexo. Conclusão: As baixas concentrações médias de hemoglobina e as altas proporções de crianças anêmicas indicam a necessidade de enfatizar, nos programas de pré-natal e puericultura do país, medidas de intervenção e controle desse distúrbio nutricional. Os fatores de risco identificados devem orientar tais ações, privilegiando grupos de maior risco como são os nascidos de baixo peso e os filhos de mães adolescentes.

ABSTRACT

Objetivo: Estimar a prevalência e a distribuiçäo social da anemia na infância, estabelecer a tendência secular dessa enfermidade e analisar sua determinaçäo, com base em dados coletados por dois inquéritos domiciliares realizados na cidade de Säo Paulo, SP, em 1984/85 e em 1995/96. Métodos: Os inquéritos estudaram amostras probabilísticas da populaçäo residente na cidade com idade entre zero e 59 meses (1.016 em 1984/85 e 1.280 em 1995/96). Amostras de sangue capilar obtidas por punctura digital foram coletadas nos dois inquéritos e analisadas com relaçäo à concentraçäo de hemoglobina. O diagnóstico da anemia correspondeu a concentraçöes inferiores a 11 g/dL. O estudo da distribuiçäo social da anemia levou em conta tercis da renda familiar per capita em cada um dos inquéritos. A estratégia analítica para estudar determinantes da evoluçäo da prevalência da anemia na populaçäo empregou modelos hierárquicos de causalidade, análises multivariadas de regressäo e procedimentos análogos aos utilizados para calcular riscos atribuíveis populacionais. Resultados/Conclusöes: Houve entre os inquéritos reduçäo significativa na concentraçäo média de hemoglobina (de 11,6 g/dL para 11,0 g/dL) e aumento significativo na prevalência de anemia (de 35,6 para 46,9 por cento). Essa evoluçäo desfavorável foi observada em ambos os sexos, em todas faixas etárias e em todos estratos econômicos da populaçäo. A evoluçäo tendeu a ser ainda mais desfavorável para o terço mais pobre das crianças da cidade, o que determinou o agravamento das desvantagens desse estrato frente aos demais. Determinantes distais (renda familiar e escolaridade materna) e proximais (tipo de aleitamento) da anemia evoluíram favoravelmente entre os inquéritos e, assim, näo puderam explicar o aumento da enfermidade. A estabilidade apurada quanto à densidade de ferro na dieta, em valores inferiores às necessidades, justifica a elevada prevalência da enfermidade, mas näo explica seu aumento

ABSTRACT

La anemia de Diamond-Blackfan es una causa poco frecuente de anemia en el recién nacido y el lactante menor. Analizamos retrospectivamente las características clínicas y de laboratorio en 20 pacientes controlados en un período de 30 años. Encontramos que en el 85 por ciento de los casos el diagnóstico se planteó antes del año de edad y la mayoría eran de sexo femenino. En 45 por ciento existía el antecedente de bajo peso de nacimiento. El principal hallazgo al examen físico, además de la palidez, fue la talla baja y no se encontraron otras malformaciones asociadas en la mayoría de los pacientes. El 100 por ciento presentaba valores de hemoglobina por debajo de los valores normales para su edad, con macrocitosis y reticulocitopenia, sin compromiso del resto de las series hematológicas. La respuesta adecuada a corticoides se observó en 85 por ciento. De los 3 pacientes refractarios, 2 fallecieron y 1 sobrevive con dependencia a transfusiones de glóbulos rojos y hemosiderosis secundaria, ya que no fue posible efectuar trasplante de médula ósea por falta de donante. El trasplante debe ser considerado precozmente como alternativa terapéutica en el grupo no respondedor a corticoides, si existe donante compatible, ya que otros tratamientos son poco exitosos

ABSTRACT

Objetivo. Conocer las prácticas transfusionales de los anestesiólogos de nuestro país. Material y Métodos. Se aplicó una encuesta durante el Curso Anual de Actualización de la Sociedad Mexicana de Anestesiología en dos años, 1996 y 1998. Metodológicamente, se dividió en tres secciones: en la primera se incluyeron cinco preguntas relacionadas a la práctica profesional, en la segunda se presentaron seis preguntas destinadas a explorar conducta transfusionales tanto para niños como para dultos, y en la tercera sección se exploraron actitudes transfusionales ante cinco situaciones hipotéticas que pudieran haberse presentado en forma aguda en el trans o postoperatorio inmediato de pacientes adultos. Resultados. En las dos aplicaciones de la encuesta, la mayoría de los que contestaron fueron anestesiólogos generales que atendían tanto paciente pediátrico como adulto. Las conductas transfusionales fueron prácticamente iguales en las dos encuestas. Con relación a las situaciones hipotéticas (pérdida menor del 10 por ciento del volumen sanguíneo circulante, pérdida del 10 - 20 por ciento del volumen sanguíneo circulante, sangrado en capa, alteraciones en las pruebas de coagulación, y datos clínicos de hipovolemia), sólo se observó una diferencia (p<0.05) entre ambas encuestas en la administración de sangre total ante una pérdida del 10 al 20 por ciento: sin embargo, considerando a los que administrarían paquete globular y sangre total, la diferencia entre las dos encuestas se pierde. Conclusiones. La encuesta permitió identificar actitudes transfusionales entre anestesiólogos de nuestro país, y estas actitudes fueron semejantes en los dos años de su aplicación

ABSTRACT

La hemorragia pulmonar masiva (HPM) es una complicaión rara del Lupus Eritematoso Generalizado (LEG); la frecuencia informada es de 1-2 por ciento. El curso clínico de la HPM es variable pero se asocia a elevada mortalidad, la cual se ha informado del 70-90 por ciento en la mayoría de las series. Su fisiopatogenia es incierta y controversial, aunque algunos autores han informado la presencia ocasional de depósitos de complejos inmunes y proteínas del complemento a nivel de los septos alveolares, así como vasculitis; sin embargo, en la mayoria de los casos informados no se encuentran estas asociaciones. Informamos 6 pacientes con LEG y HPM, en uno de ellos fue posible demostrar la presencia de depósitos de complejos inmunes de tipo IgG y complemento (C3), además de vasculitis en la biopsia pulmonar. En otros 2 casos en que efectuamos las biopsia pulmonar sólo había hemorragia reciente y macrófagos cargados de mosiderina. La mortalidad global en este informe fue del 83 por ciento, esto a pesar del uso de esteroides a dosis altas y citotóxicos
