J Trace Elem Med Biol 2023; 78:127192. [PMID: 37163818 DOI: 10.1016/j.jtemb.2023.127192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/08/2023] [Revised: 04/13/2023] [Accepted: 05/01/2023] [Indexed: 05/12/2023]
Abstract
OBJECTIVE Adverse effects of lead exposure on children's health have been demonstrated. While studies have examined the relationship between iron status and low-level lead exposure in children with blood lead levels (BLLs) < 100 μg/L, few have investigated the association between blood lead and other trace elements and anemia in children with BLLs ≥ 100 μg/L. This study aimed to assess the levels of lead, iron, copper, zinc, magnesium, and calcium in children aged 0-14 with BLLs≥ 100 μg/L between 2009 and 2021, and to examine the relationship between blood lead, trace elements and anemia. METHODS A total of 11,541 children with BLLs ≥ 100 μg/L were included in this study. Venous blood samples were collected to measure blood lead levels, hemoglobin levels, and trace element levels. According to the World Health Organization standard, outpatients with hemoglobin levels < 110 g / L were defined as having anemia. RESULTS The study results found that high BLLs and blood calcium had a negative influence on Hb with odds ratios (95% confidence interval) of 1.411(1.208, 1.649) and 1.219(1.043, 1.424). High blood iron had a positive influence on Hb with odds ratios of 0.421(0.355, 0.499). CONCLUSION The results suggest that the risk of anemia rose significantly with higher BLLs, blood copper, and blood calcium levels, and decreases considerably with higher blood iron levels.

Abstract
This work reports a portable, origami-type paper device with a plasmonic fluor-labeled microneedle sensing module for the multiplexed quantification of anemia biomarkers in whole blood. Sequential steps, including serum separation, target enrichment, and multiplexed readout by a gel imager, are rapidly accomplished with the flexible and highly integrated device. The microneedle array enabled efficient sampling of trace targets from ng mL-1 to pg mL-1 level. Combined with the plasmonic fluor label, the signal is improved by ≈7.6 folds compared with the flat substrate-based assay. The device is applied to simultaneously quantify hemoglobin (Hb), ferritin, folic acid (FA), and vitamin B12 (VB12 ), which are four anemia biomarkers distributed in different environments with different concentration ranges. Featured by the small sample volume (150 µL), short assay time (20 min), low cost (2 $), robust stability, and user-friendliness, the device is promising for the rapid and accurate diagnosis of anemia in real practice.

Abstract
The aim of this study was to analyse and compare the acidity, microbiological and colour characteristics, fatty (FA) and amino (AA) acid profiles, biogenic amine (BA) and gamma-aminobutyric acid (GABA) concentrations, and macro- and microelement contents in non-treated (non-fermented) and fermented wholemeal cereal flours of ‘Gaja’ (traditional wheat) and new breed lines DS8888-3-6 (waxy wheat), DS8548-7 (blue wheat) and DS8535-2 (purple wheat). Independent fermentations were undertaken with selected strains of Pediococcus acidilactici, Liquorilactobacillus uvarum and Lactiplantibacillus plantarum. The results revealed that all the wholemeal cereal flours of the analysed wheat varieties are suitable for fermentation with the selected strains because all the fermented samples showed lactic acid bacteria (LAB) viable counts higher than 8.00 log10 CFU/g and desirable low pH values. In most of the cases, fermentation increased the concentration of essential amino acids in the wholemeal cereal samples, and the LAB strain used for fermentation proved to be a significant factor in all the essential amino acid content of wholemeal wheat (p ≤ 0.0001). When comparing the non-fermented samples, the highest GABA content was found in ‘Gaja’ and waxy wheat samples (2.47 µmol/g, on average), and, in all the cases, fermentation significantly increased GABA concentration in the wholemeal cereals. On the other hand, total levels of biogenic amines in wholemeal samples ranged from 22.7 to 416 mg/kg. The wheat variety was a significant factor in all the analysed macro- and microelement contents (p ≤ 0.0001) in the wholemeal cereals. Furthermore, fermentation showed to be a significant factor in most of the FA content of the wholemeal cereal samples. Finally, fermentation can also contribute to improving the biological and functional value of wholemeal wheat flours (by increasing essential amino acids and GABA concentrations); however, safety parameters (e.g., biogenic amines) also should be taken into consideration when optimizing the most appropriate technological parameters.

Abstract
BACKGROUND Slum dwellers display specific traits when it comes to disclosing their illnesses to professionals. The resulting actions lead to poor health-seeking behaviour and underutilisation of existing formal health facilities. The ways that slum people use to communicate their feelings about illness, the type of confidants that they choose, and the supportive and unsupportive social and cultural interactions to which they are exposed have not yet been studied in the Indian context, which constitutes an important knowledge gap for Indian policymakers and practitioners alike. To that end, this study examines the patterns of illness disclosure in Indian slums and the underpinning factors which shape the slum dwellers' disclosing attitude. METHODS In-depth, semi-structured interviews were conducted among 105 men and 113 women who experienced illness in the year prior to the study period. Respondents were selected from four urban slums in two Indian cities, Bangalore and Kolkata. RESULTS Findings indicate that women have more confidants at different social levels, while men have a limited network of disclosures which is culturally and socially mediated. Gender role limitations, exclusion from peer groups and unsupportive local situations are the major cause of disclosure delay or non-disclosure among men, while the main concerns for women are a lack of proper knowledge about illness, unsupportive responses received from other people on certain occasions, the fear of social stigma, material loss and the burden of the local situation. Prompt sharing of illness among men is linked with prevention intention and coping with biological problems, whereas factors determining disclosure for women relate to ensuring emotional and instrumental safety, preventing collateral damage of illness, and preventing and managing biological complications. CONCLUSIONS The findings reveal that patterns of disclosure are not determined by the acknowledgment of illness but largely depend on the interplay between individual agency, disclosure consequences and the socio cultural environment. The results of this study can contribute significantly to mitigating the pivotal knowledge gap between health policymakers, practitioners and patients, leading to the formulation of policies that maximise the utilisation of health facilities in slums.

Abstract
We studied the effect of chronic oral exposure to lead acetate (PbA) on the sensitivity of RBC to hemolysis and whether the sensitivity could be decreased by feeding the rats with extract of medicinal mushroom Ganoderma lucidum. Three groups of rats, control, PbA-exposed, and G. lucidum (Gl)+PbA, were used. PbA (3 mM) was administered via drinking water and G. lucidum extract by gavage at 300 mg/Kg BW/day for 12 weeks. Afterwards, the rats were killed and washed RBCs were subjected to hemolysis in the presence of Fenton's reagents. Hemolysis was determined by estimating the amount of released hemoglobin. The levels of lipid peroxide (LPO) and GSH were determined from RBC membranes and whole RBCs, respectively. The levels of TNFα and LPO also were determined from hepatic tissues. The RBCs of PbA-exposed rats displayed significantly higher sensitivity to hemolysis than those of the Gl+PbA rats. The levels of LPO increased and GSH decreased in the RBCs, with concomitant increases in the levels of hepatic TNFα and LPO in the PbA-exposed rats. The degree of hemolysis was significantly low in the RBCs of Gl+PbA rats, concurrently with amelioration of hepatic parameters. Finally, the study suggests that PbA-induced-hemolysis and related oxidative-toxicity might be minimized by consumption of G. lucidum.

Abstract
Background. India is the highest contributor to child anemia. About 89 million children in India are anemic. The study determines the factors that contributed to child anemia and examines the role of the existing programs in reducing the prevalence of child anemia particularly in the EAG states. Methods. The data from the latest round of the National Family Health Survey (NFHS-3) is used. Simple bivariate and multinomial logistics regression analyses are used. Results. About 70% children are anemic in all the EAG states. The prevalence of severe anemia is the highest (6.7%) in Rajasthan followed by Uttar Pradesh (3.6%) and Madhya Pradesh (3.4%). Children aged 12 to 17 months are significantly seven times (RR = 7.99, P < 0.001) more likely to be severely anemic compared to children of 36 to 59 months. Children of severely anemic mothers are also found to be more severely anemic (RR = 15.97, P < 0.001) than the children of not anemic mothers. Conclusions. The study reveals that the existing government program fails to control anemia among preschool children in the backward states of India. Therefore, there is an urgent need for monitoring of program in regular interval, particularly for EAG states to reduce the prevalence of anemia among preschool children.

Abstract
BACKGROUND The worldwide incidence rates of hepatocellular carcinoma (HCC) vary widely. Some countries like India have a low incidence despite having a large burden of chronic hepatitis B (HBV) and C virus (HCV) infection. We hypothesized that long-term iron deficiency could attenuate the hepatic inflammation and lead to a lower incidence of HCC in India than expected. METHODS We evaluated the association of serum ferritin levels and HCC in Indian patients with HBV- or HCV-related chronic liver disease (CLD) using a case-control study design. We enrolled 141 patients with HCC (cases) and 240 patients having chronic HBV or HCV infection-related CLD (controls). Study participants were grouped on the basis of ferritin values into low-normal, high-normal, and high subgroups. RESULTS Mean ferritin values were higher in cases as compared to controls (425.8 vs. 135.6 ng/mL, p = 0.000). A significant dose-response effect for serum ferritin levels and HCC was seen with an odds ratio (95 % confidence interval) of 3.0 (1.6-5.9, p = 0.001) for subjects with high-normal ferritin levels and 8.2 (4.1-16.5, p = 0.000) for subjects with high ferritin levels in a multivariate model. Other significant independent risk factors in the multivariate model included older age, male gender, alcohol and tobacco use, elevated alanine aminotransferase, higher family income, and coffee drinking. CONCLUSION We found an independent association between serum ferritin levels and HCC in patients with CLD of viral etiology. Further prospective studies are needed to confirm the hypothesis that iron deficiency protects against HCC in CLD.

Abstract
OBJECTIVES To examine the patterns of social inequalities in anaemia over time among women of reproductive age in India. DESIGN Repeated cross-sectional study using nationally representative data from the 1998/1999 and 2005/2006 National Family Health Surveys of India. Multivariate modified Poisson regression models were used to assess trends and social inequalities in anaemia. SETTING India. POPULATION 164 600 ever-married women aged 15-49 years (n=79 197 in 1998/1999 and n=85 403 in 2005/2006) from 25 Indian states. MAIN OUTCOME MEASURE Anaemia status defined by haemoglobin level (<12 g/dl in non-pregnant women, haemoglobin<11 g/dl for pregnant women). RESULTS Over the 7-year period, anaemia prevalence increased significantly from 51.3% (95% CI 50.6% to 52%) to 56.1% (95% CI 55.4% to 56.8%) among Indian women. This corresponded to a 1.11-fold increase in anaemia prevalence (95% CI 1.09 to 1.13) after adjustment for age and parity, and 1.08-fold increase (95% CI 1.06 to 1.10) after further adjustment for wealth, education and caste. There was marked state variation in anaemia prevalence; in only 4 of the 25 states did anaemia prevalence significantly decline. In both periods, anaemia was socially patterned, being positively associated with lower wealth status, lower education and belonging to scheduled tribes and scheduled castes. In this context of overall increasing anaemia prevalence, adjusted relative and absolute socioeconomic inequalities in anaemia by wealth, education and caste have narrowed significantly over time. CONCLUSIONS The significant increase in anaemia among India's women during this recent period is a matter of concern, and in contrast to secular improvements in other markers of women's health and nutritional status. While socioeconomic inequalities in anaemia persist, the relative and absolute inequalities in anaemia have decreased over time. Future research should explore the causes for these changing patterns, and inform the policy and programmatic response to address anaemia and its inequalities in this vulnerable population.

Abstract
BACKGROUND In India, 55% of women and 69.5% of preschool children are anaemic despite national policies recommending routine iron supplementation. Understanding factors associated with receipt of iron in the field could help optimise implementation of anaemia control policies. Thus, we undertook 1) a cross-sectional study to evaluate iron supplementation to children (and mothers) in rural Karnataka, India, and 2) an analysis of all-India rural data from the National Family Health Study 2005-6 (NFHS-3). METHODS All children aged 12-23 months and their mothers served by 6 of 8 randomly selected sub-centres managed by 2 rural Primary Health Centres of rural Karnataka were eligible for the Karnataka Study, conducted between August and October 2008. Socioeconomic and demographic data, access to health services and iron receipt were recorded. Secondly, NFHS-3 rural data were analysed. For both studies, logistic regression was used to evaluate factors associated with receipt of iron. RESULTS The Karnataka Study recruited 405 children and 377 of their mothers. 41.5% of children had received iron, and 11.5% received iron through the public system. By multiple logistic regression, factors associated with children's receipt of iron included: wealth (Odds Ratio (OR) 2.63 [95% CI 1.11, 6.24] for top vs bottom wealth quintile), male sex (OR 2.45 [1.47, 4.10]), mother receiving postnatal iron (OR 2.31 [1.25, 4.28]), mother having undergone antenatal blood test (OR 2.10 [1.09, 4.03]); Muslim religion (OR 0.02 [0.00, 0.27]), attendance at Anganwadi centre (OR 0.23 [0.11, 0.49]), fully vaccinated (OR 0.33 [0.15, 0.75]), or children of mothers with more antenatal health visits (8-9 visits OR 0.25 [0.11, 0.55]) were less likely to receive iron. Nationally, 3.7% of rural children were receiving iron; this was associated with wealth (OR 1.12 [1.02, 1.23] per quintile), maternal education (compared with no education: completed secondary education OR 2.15 [1.17, 3.97], maternal antenatal iron (2.24 [1.56, 3.22]), and child attending an Anganwadi (OR 1.47 [1.20, 1.80]). CONCLUSION In rural India, public distribution of iron to children is inadequate and disparities exist. Measures to optimize receipt of government supplied iron to all children regardless of wealth and ethnic background could help alleviate anaemia in this population.

Abstract
Anemia is common during adolescence. However, severe anemia is uncommon and can have varied etiology. This study was conducted to find out the profile of adolescents (10-18 years) admitted for severe anemia. The Case records of children between 10 and 18 years old admitted during the year 2008 in Kalawati Saran Children's Hospital for severe anemia as admitting diagnosis were reviewed. There were 40 patients admitted with severe anemia during the year 2008. This constituted 3.37% of all the admissions. Mean age of these patients was 12 (+/-2.5) years and mean hemoglobin at admission was 3.6 (+/-1.4) g%. Megaloblastic anemia was most common type of anemia (42.5%) followed by aplastic anemia (27.5%) and 15% cases were due to severe iron deficiency anemia. Although iron deficiency anemia is the most common type of anemia, but in adolescents megaloblastic anemia and aplastic anemia should be looked for whenever the adolescents present with severe anemia.

Abstract
Iron (Fe) deficiency is the most common nutritional problem among children and lead (Pb) toxicity is the most common environmental health threat to children all over the world. The objective of this study was to determine blood lead (BPb) levels and prevalence of Fe deficient anemia among 1 to 5year old children attending day care clinic in pediatric ward of civil hospital Karachi, Pakistan. A total of 340 children of both genders participating in this study, were screened for anemia. Among them 215 were anemic and 125 non-anemic. The anemic group was further divided in two groups on the basis of % hemoglobin (Hb), mild (Hb <10g/dL) and severe anemic group (Hb <8g/dL), while non-anemic as referent children (Hb >10g/dL). The blood samples were analysed for Pb and Fe, along with hematological parameters. The result indicated that anemic children had a higher mean values of Pb in blood than referent children with Hb >10g/dL. The Pb levels <100μg/L were detected in 40% referent children while 60% of them had >10μg/dL. The BPb concentration in severe anemic children (53%) was found in the range of 100-200μg/L, whereas 47% had >200μg/L. The significant negative correlations of BPb level with % Hb (r=-0.514 and r=-0.685) and Fe contents (r=-0.522, r=-0.762, p<0.001) were observed in mild and severe anemic children respectively. While positive correlation was observed between BPb and age of both group and genders (r=0.69, p<0.01). The BPb levels were significantly associated with biochemical indices in the blood which have the potential to be used as biomarkers of Pb intoxication and Fe deficient anemia.

Abstract
The authors describe 10 cases of myelofibrosis diagnosed and managed at their center over 16 years. There were 2 and 8 cases, respectively, of primary and secondary myelofibrosis. All patients presented with fever, pallor, hepatosplenomegaly, and/or lymphadenopathy. Hodgkin's lymphoma (n = 4), neuroblastoma (n = 1), thrombasthenic thrombopathy (n = 1), and retroperitoneal-mass (n = 1) were causal in 7 patients, whereas the diagnosis could not be established in a sole case of secondary myelofibrosis. Patients were managed with chemotherapy and appropriate care. However, outcome was poor. The authors emphasize variable clinical-laboratory spectrum of myelofibrosis, highlight management concerns, and demonstrate that prognosis/outcome depends upon appropriate management of the underlying condition.

Abstract
BACKGROUND Anemia is a health problem among infants and children. It is often associated with a decrease in some trace elements (iron, zinc, copper) and an increase in heavy metals as lead. This study was done to determine the association of blood lead level > 10 mug/dl, with the increased risk to anemia, also, to investigate the relationship between anemia and changes in blood iron, zinc and copper levels, and measure lead level in drinking water.The study is a cross-sectional performed on 60 children. Venous blood samples were taken from the studied population for estimating hematological parameters as well as iron and ferritin levels. The concentrations of zinc, copper, and lead were measured. The studied population was divided into anemic and non-anemic (control) groups. The anemic group was further classified into mild, moderate and severe anemia. The study subjects were also categorized into low and high blood lead level groups. FINDINGS Approximately 63.33% of children had blood lead levels >/= 10 mug/dl. At the blood lead level range of 10-20 mug/dl, a significant association was found for mild and severe anemia. The blood level of iron and ferritin was found to be significantly lower in high blood lead level and anemic groups than those of the low blood lead level and control groups. Lead level in drinking water was higher than the permissible limit. CONCLUSION Lead level >/= 10 mug/dl was significantly associated with anemia, decreased iron absorption and hematological parameters affection. High blood lead levels were associated with low serum iron and ferritin. Lead level in drinking water was found to be higher than the permissible limits.

Abstract
1. It has been argued that all major risk factors for cardiovascular disease have been identified. Yet, epidemiological studies undertaken to identify risk factors have largely focused on populations in developed nations or on the urban or relatively affluent rural populations of developing countries. Poor rural populations are seldom studied. 2. Somewhat different risk factors may operate in poor rural populations. Evidence for this is provided by the finding that, in disadvantaged rural India, the prevalence of hypertension is greater than would be expected based on established risk factors in these populations. One risk factor to be considered is a poor intrauterine environment. 3. In animals, maternal macro- and micronutrient malnutrition can lead to reduced nephron endowment. Nephron deficiency, in turn, can render blood pressure salt sensitive. The combination of nephron deficiency and excessive salt intake will predispose to hypertension. 4. Human malnutrition may have similar effects, particularly in regions of the world where malnutrition is endemic and where women are disadvantaged by existing social practices. 5. Moreover, high salt intake is endemic in many parts of Asia, including India. Therefore, we propose that maternal malnutrition (leading to reduced nephron endowment), when combined with excessive salt intake postnatally, will account, at least in part, for the unexpectedly high prevalence of hypertension in disadvantaged rural communities in India and elsewhere.

Abstract
OBJECTIVES To investigate, in asylum seekers' children in the Netherlands, biochemical iron status and the prevalence of iron deficiency (ID) and anemia in relation to age, region of origin, length of stay in the Netherlands, body mass index (BMI), and dietary iron intake. PATIENTS AND METHODS Hemoglobin (Hb) and plasma ferritin concentrations were determined in 122 asylum seekers' children (median age, 7.1 years; range, 2-12 y). ID was defined by plasma ferritin levels <15 microg/L. Anemia was defined by Hb levels <6.8 mmol/L (11 g/dL) for children <6 years of age and Hb levels <7.1 mmol/L (11.5 g/dL) for children between 6 and 12 years of age. Nutritional status of the children was assessed by BMI and dietary intake of iron was estimated by 24-hour recall. RESULTS Twenty percent of the children had compromised iron status (16% with ID, 4% with ID anemia [IDA]). Another 6% of the children had anemia caused by thalassemia. ID was significantly more prevalent in children <6 years of age and in children of African origin. The iron status was not significantly correlated with the length of stay in the Netherlands (r = 0.6; P = 0.48). Higher BMI z scores were positively correlated with iron status. Adequate or marginal dietary iron intake was not significantly related to the presence of ID (r = 0.02; P = 0.9) or anemia (IDA and thalassemia; r = 0.15; P = 0.9). CONCLUSIONS Iron deficiency is highly prevalent among the children of asylum seekers in the Netherlands. Our data indicate that systematic biochemical screening for ID is warranted in asylum seekers' children.

Abstract
This paper describes trends in HIV-related morbidity among people living with HIV/AIDS (PLWHA) admitted to a tertiary hospital in Chennai, South India, between 1997 and 2003. Patients comprised HIV-infected men, women and children who had been admitted at least once to YR Gaitonde Centre for AIDS Research and Education (YRGCARE). A non-parametric trends analysis was conducted to observe trends in clinical and demographic parameters and diagnoses at admission over the seven-year period. Among clinical and demographic parameters, we identified a significantly increasing time trend in the use of antiretroviral therapy (p<0.001) and a significant decrease in the mean hemoglobin level (p=0.01). Among diagnoses at admission, we identified a decreasing time trend for admissions due to pulmonary tuberculosis (p<0.001) and increasing trends for admissions due to extra pulmonary tuberculosis (p<0.01), toxoplasmosis (p<0.01), Pneumocystis carinii pneumonia (p=0.02) and anemia (p<0.001). The results indicate a changing pattern among the clinical conditions requiring admission. With increasing proportions of patients initiating highly active antiretroviral therapy (HAART), it is probable that adverse events due to HAART will account for larger proportions of admissions in the years to come, as is being seen in the industrialized countries.

Abstract
The prevalence rates of hypoferritinemia (IDec/one abnormal indicator), iron deficiency (IDef/two abnormal indicators) and iron deficiency anemia (IDA) in children who were referred to the outpatient clinics of the Department of Pediatrics for the first time within 1 month were investigated. Exclusion criteria were iron therapy before and during the study period and a history of chronic illness. Acute-phase reactants, such as erythrocyte sedimentation rate and C-reactive protein levels, were measured in all cases indicative of infectious diseases. Blood samples were obtained from each study patient admitted to the outpatient clinics during the study period. The hospital charts were later further evaluated, and samples of patients with any current illness known to interact with the iron status of the patient were discarded, and patients were contacted to supply new samples about 1 month after treatment of the infection. Thus, in patients with indications of an infection, samples obtained 1 month after treatment were assessed. The children (n = 557) were divided into four age groups: those aged 4 months to 2 years (group I), 2-6 years (group II), 7-12 years (group III) and 12-18 years (group IV). Children with a decrease in serum ferritin levels without anemia (IDec), and those with lower ferritin, transferrin saturation (TS) and serum iron (SI) concentration (IDef) were evaluated. IDA was diagnosed if hemoglobin (Hb) concentrations were lower than those adjusted for age, ferritin <12 ng/ml and TS <or=16% and if SI was decreased. IDec, IDef and IDA were detected in 26, 11.1 and 12.7% of the patients, respectively. Only 50.1% of the patients visiting the outpatient clinics were found to be normal. The rates of IDec (28.9%), IDef (21.9%) and IDA (26.2%) were highest in group I. IDec had the highest percentages in all groups. In group I, the rates of IDec, IDef, and IDA were 37.2, 66.1 and 69%, respectively. SI concentration was abnormal in 77.1% of the cases in group I (4 months to 2 years of age). Half of the patients referred to the outpatient clinics were suffering from abnormalities related to lower SI concentrations. Close monitoring and treatment of iron deficiency is advised especially in early childhood.

Abstract
A cross-sectional method was used to study a group of 400 high school students in Kocaeli, Turkey, aged 14 to 16 years, identified among 17,812 high school students. Students from 10 high schools were selected using a random sampling method. Whole blood counts were performed as a screening test for anemia. Serum ferritin levels and, when necessary, hemoglobin electrophoresis were determined for anemic students. Iron medication was prescribed for iron deficiency and genetic counseling was given to adolescents with thalassemia trait. Out of 338 participating students (mean age, 14.72+/-0.71 y), anemia (hemoglobin <12 g/dL for girls and <13 g/dL for boys) was detected in 17/174 girls (9.7%) and 6/164 boys (3.6%). Iron deficiency anemia was detected in 20/23 (86.9%) of anemic children [15/17 (88.2%) girls and 4/6 (66.6%) boys]. Of 23 students with anemia 2 had beta-thalassemia trait and 2 had both iron deficiency, and beta-thalassemia trait. Etiology of anemia could not be defined in 1 student. The prevalence of adolescent anemia in Kocaeli is almost equal to that in developed countries.

Abstract
Lead pollution is a substantial problem in developing countries such as India. The US Centers for Disease Control and Prevention has defined an elevated blood lead level in children as > or = 10 microg/dl, on the basis of neurologic toxicity. The US Environmental Protection Agency suggests a threshold lead level of 20-40 microg/dl for risk of childhood anemia, but there is little information relating lead levels <40 microg/dl to anemia. Therefore, the authors examined the association between lead levels as low as 10 mug/dl and anemia in Indian children under 3 years of age. Anemia was divided into categories of mild (hemoglobin level 10-10.9 g/dl), moderate (hemoglobin level 8-9.9 g/dl), and severe (hemoglobin level <8 g/dl). Lead levels <10 mug/dl were detected in 568 children (53%), whereas 413 (38%) had lead levels > or = 10-19.9 microg/dl and 97 (9%) had levels > or = 20 microg/dl. After adjustment for child's age, duration of breastfeeding, standard of living, parent's education, father's occupation, maternal anemia, and number of children in the immediate family, children with lead levels > or = 10 microg/dl were 1.3 (95% confidence interval: 1.0, 1.7) times as likely to have moderate anemia as children with lead levels <10 microg/dl. Similarly, the odds ratio for severe anemia was 1.7 (95% confidence interval: 1.1, 2.6). Health agencies in India should note the association of elevated blood lead levels with anemia and make further efforts to curb lead pollution and childhood anemia.

Abstract
Ferritin, a major form of endogenous iron in food legumes such as soybeans, is a novel and natural alternative for iron supplementation strategies where effectiveness is limited by acceptability, cost, or undesirable side effects. A member of the nonheme iron group of dietary iron sources, ferritin is a complex with Fe3+ iron in a mineral (thousands of iron atoms inside a protein cage) protected from complexation. Ferritin illustrates the wide range of chemical and biological properties among nonheme iron sources. The wide range of nonheme iron receptors matched to the structure of the iron complexes that occurs in microorganisms may, by analogy, exist in humans. An understanding of the chemistry and biology of each type of dietary iron source (ferritin, heme, Fe2+ ion, etc.), and of the interactions dependent on food sources, genes, and gender, is required to design diets that will eradicate global iron deficiency in the twenty-first century.

Abstract
OBJECTIVE The incidence and the risk factors of sickle cell disease (SCD), vaccinated with Pneumococcal vaccine and on penicillin prophylaxis has not been previously reported in India. METHODS This prospective hospital based study followed 325 children on penicillin prophylaxis, of which 161 were vaccinated for pneumococci, over 146.84 person years to determine the incidence and determinants of crisis (SCC) and infections. The average age at presentation was 7.05 +/- 3.26 years with male preponderance below 2 years. RESULTS The main causes for hospitalizations were for blood transfusion, SCC and infections. The incidence of SCC was 1.25 per patient per year and that of infection was 1.38 per person per year. The risk factors for SCC were Mahar caste (p = 0.007) non-compliance (p = 0.000) and protein energy malnutrition (PEM) (p = 0.0015) and for infection were also PEM (p = 0.023), Mahar caste (p = 0.021) and noncompliance (p = 0.001). CONCLUSION Malnutrition and non-compliance with medication increased the patient's susceptibility to SCC and infections.
