Studies had shown that iron-cycling was disturbed by inflammatory process through the role of hepcidin. Pregnancy is characterized by shifts of interleukin. Our objective was to determine if 25(OH) vitamin D (colecalciferol) status was associated with ferritin, anemia, and its changes during pregnancy. Method. A cohort study was done in 4 cities in West Java, Indonesia, beginning in July 2016. Subjects were followed up until third trimester. Examinations included were maternal ferritin, colecalciferol, and haemoglobin level. Result. 191 (95.5%) subjects had low colecalciferol, and 151 (75.5%) among them were at deficient state. Anemia is found in 15 (7.5%) subjects, much lower than previous report. Proportion of anemia increased by trimester among women with colecalciferol deficiency. Ferritin status and prepregnancy body mass index in the first trimester were correlated with anemia (r = 0.147, p = 0.038 and r = −0.56, p = 0.03). Anemia in the second trimester was strongly correlated with anemia in the third trimester (r = 0.676, p < 0.01). Conclusion. Our study showed that the state of colecalciferol was not associated with either ferritin state or anemia, but proportion of anemia tends to increase by trimester in the colecalciferol deficient subjects.

Industrial waste in paddy field leads to accumulation of heavy metals in the soils. The availability of heavy metal on the soil can affect soil quality and plant growth. The objectives of this research were to obtain the best dosage of bio agent-added organomineral nitrogen fertilizer (ONF+BA) for the improvement of soil quality and paddy rice grown in industrial-waste contaminated soil. Randomized block design were applied with six single treatments: 150 kg ONF+BA (A), 200 kg ONF+BA (B), 250 kg ONF+BA (C), 300 kg ONF+BA (D), 350 kg ONF+BA (E), 250 kg urea (F), each treatment was replicated five times. The result showed that the application of ONF+BA reduced lead (Pb) and chrome (Cr) solubility and foliar accumulation, improved plant growth, and increase foliage nitrogen content. The doses of 300 kg ONF+BA shown highest lead and chrome solubility reduction, while 350 kg ONF+BA decrease foliar accumulation of lead and chrome.

Respiratory distress syndrome (RDS) or hyaline membrane disease is the most frequent cause of respiratory failure and mortality in preterm infants. As a result, many infants are brought to a neonatal intensive care unit (NICU). There may also be other factors that affect the incidence rate of RDS as well. Our research goals are to find out the incidence rate of RDS among three preterm groups and its related factors. In a cross-sectional-descriptive analytical study, newborn data was gathered and assessed by using hospital medical records. One hundred forty-two preterm infants with gestational age ≤ 36 weeks were hospitalized in the NICU. All participants were divided into three groups: extremely preterm ( 28 weeks), very preterm (28 to 32 weeks), and moderate-to-late preterm (32 to 36 weeks). The frequency of RDS and some related factors were compared among three groups. Finally, we analyzed the relationship between variables by SPSS statistics software version 19. The level of significance was considered P 0.05. Respiratory distress syndrome was observed in 64.68% of all participants; RDS is more common in infants within 28-32 weeks of gestation (81%), while infants with 28 weeks of gestation and 33-36 weeks of gestation have lower rates (50% and 52 Our study shows a positive correlation between birthweight and RDS as well as between birthweight and gestational age. (P value: 0.001, 0.003). Infants between 28 to 32 gestational age have a higher risk of RDS. The risk of RDS also increases in low birth weight and male infants.
