Background: Anemia is a global public health problem that occurs in developed countries or in developing countries. The prevalence of anemia in children aged 1-5 years in the United States is 3.9% and iron anemia is 1.1%. This review discussed prevalence and the risk factors and anemia in children in developed countries. Method: The method used is a literature review, the data source in the form of research articles is obtained from online databases, namely Google Scholar and Science Direct. The articles reviewed were 10 articles that met the inclusion criteria. Result: Based on several studies, iron deficiency or deficiency is the most common cause in children in developed countries. 8% of children under five in the United States have iron deficiency, and 2-3% of them are iron deficiency anemia. Risk factors for anemia include lack of serum zinc, low levels of 25 (OH) D, exclusive breastfeeding without iron fortification, Low Birth Weight (LBW), food intake factors, history of asthma and eczema, and maternal education. Iron deficiency anemia in childhood has been shown to have a negative effect on cognitive and psychomotor development. Prevention of anemia that can be done include giving iron supplements and food recommendations. Conclusion: Risk factors for anemia include lack of serum zinc, low 25 (OH) D levels, exclusive breastfeeding without iron fortification, Low Birth Weight (LBW), food intake factors, history of asthma and eczema, and maternal education.

Abstract. Despite the high prevalence of coronary artery disease (CAD) among patients with end-stage renal disease (ESRD), few studies have identified clinical correlates using national data. The purpose of this study was to determine the prevalence and clinical associations of CAD in a national random sample of new ESRD in the United States in 1996/1997 (n = 4025). Data on demographic characteristics and comorbidities were obtained from the Dialysis Morbidity and Mortality Study, Wave 2. The principal outcome was CAD, defined as the presence of a previous history of CAD, myocardial infarction, or angina, coronary artery bypass surgery, coronary angioplasty, or abnormal coronary angiographic findings. Multivariate logistic regression analysis was used to assess the relationship of conventional factors and proposed uremic factors to the presence of CAD. CAD was present in 38% of patients. Of the total cohort, 17% had a history of myocardial infarction and 23% had angina. Several conventional risk factors, including advancing age, male gender, diabetes mellitus, and smoking, were significantly associated with CAD. Of the proposed uremic factors, lower serum albumin levels but higher residual renal function and higher hematocrit values were significantly associated with the presence of CAD. Vascular comorbid conditions, structural cardiac abnormalities, white race, and geographic location were also strongly correlated with the presence of CAD. This national study suggests that several conventional CAD risk factors may also be risk factors for CAD among the ESRD population. This study identifies nonconventional factors such as serum albumin levels, vascular comorbid conditions, and structural cardiac abnormalities as important disease correlates. Future logitudinal studies are required to explore the relative importance of the relationships observed here.

Abstract The high incidence of iron deficiency anemia in the United States and elsewhere is caused by insufficient iron intake, plus poor utilization of many dietary sources of iron. There is need to select assimilable sources of iron for fortification of foods; animal studies show that many of the iron compounds used for cereal enrichment are poorly utilized. A method to measure availability of iron is proposed and is currently being studied collaboratively. Preliminary data indicate that in vitro solubility tests are not satisfactory to evaluate availability of iron supplements.

Metastatic soft tissue mineralization has emerged as a major cause of death in captive Komodo dragons ( Varanus komodoensis ). A cross-sectional survey-based study was performed to evaluate husbandry-related risk factors for metastatic mineralization in zoo-housed Komodo dragons in the United States. Nineteen institutions participated, nine of which (47.4%) had a history of metastatic mineralization within their collections. Husbandry at participating institutions varied in temperature gradients, outdoor exposure, artificial lighting, and diet items offered. Differences in husbandry were tested between institutions with and without a history of mineralization using univariate analyses, and variables resulting in a significance level ≤0.10 were entered into a multinomial logistic regression model. The only variable demonstrating a significant difference during univariate analyses was the number of dragons per enclosure ( p =0.036), while the only significant predictive variable after modeling was humidity approximation. Zoos that approximated rather than measured humidity were 12.0 times as likely to have a history of mineralization in their Komodo dragons (OR 12.0, p =0.045). These variables likely reflect the under- or overestimation of exhibit humidity levels, and the tendency to house males and females together. Based on post-mortem findings for 27 dragon mortalities from these institutions, the presence of mineralization at necropsy was significantly associated with female dragons (OR 18.2, p =0.0044) and yolk coelomitis or embolism (OR 6.76, p =0.046). Although this study did not identify definitive links between husbandry and the prevalence of mineralization at the institutional level, the survey revealed high variation in husbandry conditions, and potential

Prevalence Of Anemia

Iron deficiency anemia was common and often severe as recently as 15 years ago in the United States.1 During that period, it had become a well-established routine to evaluate all term infants for anemia at about 1 year of age2; screening at the preschool checkup and in adolescence also became widespread. Declining Prevalence of Iron Deficiency Anemia During the past decade, iron deficiency anemia has become less and less common.1,3 The first strong evidence of a relatively low nationwide prevalence of anemia was provided by the second National Health and Nutrition Examination Survey (NHANES II) conducted between 1976 and 1980.4 In that large, representative sampling of the US population, only about 6% of adolescent girls between 15 and 17 years of age were anemic.4

This chapter interrogates public understandings of mass shootings. First of all, gun violence statistics for the United States are compared with those in other developed countries. The varying definitions and trends of mass shooting are shown to be problematic in trying to gain an accurate understanding of the phenomenon. Discussed is the history of mass shootings in the United States from “going postal” attacks occurring in post offices and workplace massacres through to school shootings and mass shootings in public places. Possible reasons why the United States has the highest number of mass shootings are deliberated. Hofstede's often-quoted cultural model is used to discuss two national characteristics: high levels of individualism and low power distance between social groups. Other factors highlighted relate to Harding, Fox, and Mehta's model about influencers of school shootings, as well as notions of extreme masculinity which are often expressed via misogynistic behavior.

Iron deficiency and iron deficiency anemia (IDA) affect approximately two billion people worldwide and most of them reside in low- and middle-income countries. In these countries, additional causes of anemia include parasitic infections like malaria, other nutritional deficiencies, chronic diseases, hemoglobinopathies and lead poisoning. Maternal anemia in resource-poor nations is associated with low birth weight, increased perinatal mortality and decreased work productivity. Maintaining a normal iron balance in these settings is challenging, as iron-rich foods with good bioavailability are of animal origin that are expensive and/or available in short supply. Apart from infrequent consumption of meat, inadequate vitamin C intake and diets rich in inhibitors of iron absorption are additional important risk factors for IDA in low-income countries. In-home iron fortification of complementary foods with micronutrient powders has been shown to effectively reduce the risk of iron deficiency and IDA in infants and young children in developing countries but is associated with unfavorable changes in gut flora and induction of intestinal inflammation that may lead to diarrhea and hospitalization. In developed countries, iron deficiency is the only frequent micronutrient deficiency. In the industrialized world, IDA is more common in infants beyond the sixth month of life, in adolescent females with heavy menstrual bleeding, in women of childbearing age and elderly people. Other special at-risk populations for IDA in developed countries are regular blood donors, endurance athletes and vegetarians. Several medicinal ferrous or ferric oral iron products exist, and their use is not apparently associated with harmful effects on the overall incidence of infectious illnesses in sideropenic and/or anemic subjects. Further research is needed to clarify the risks and benefits of supplemental iron for children exposed to parasitic infections in the third world, and for children genetically predisposed to iron overload.

Background. Iron deficiency continues to be a common problem among infants throughout the world. Iron-fortified formula is effective in preventing iron deficiency but the benefit of iron-fortified cereal is controversial. Methods. We compared iron-fortified rice cereal to unfortified rice cereal in infants who were exclusively breast-fed for more than 4 months and to iron-fortified formula in infants who were weaned to formula before 4 months of age. The design was double blind in respect to the presence or absence of fortification iron in the cereal or formula and included 515 infants who were followed on the protocol from 4 to 15 months of age. Rice cereal was fortified with 55 mg of electrolytic iron per 100 g of dry cereal and infant formula with 12 mg of ferrous sulfate per 100 g of dry powder, levels approximating those in use in the United States. Measures of iron status were obtained at 8, 12, and 15 months. Infants with hemoglobin levels of <105 g/L were excluded from the study and treated. Results. Consumption of cereal reached plateaus at means of about 30 g/d after 6 months of age in the formula-fed groups and 26 g/d after 8 months in the breast-fed groups; these amounts are higher than the 19-g/d mean intake by the 73% of infants who consume such cereal in the United States. Among infants weaned to formula before 4 months, the cumulative percentages of infants excluded for anemia by 15 months were 8%, 24%, and 4%, respectively, in the fortified cereal, unfortified cereal and formula, and fortified formula groups (P < .01 unfortified vs either fortified group; the difference between the two fortified groups was not significant). In infants breast-fed for more than 4 months, the corresponding values were 13% and 27%, respectively, in the fortified and unfortified cereal groups (P < .05). Mean hemoglobin level and other iron status measures were in accord with these findings. Conclusion. Iron-fortified infant rice cereal can contribute substantially to preventing iron deficiency anemia.
