Polyaniline Modified Thin-film Array for Sensor Applications

Abstract: In this work, a pH sensor based on polyaniline-modified thin-film interdigitated array (IDA) microelectrodes was presented. Aniline was electropolymerized on the surface of IDA working electrodes by means of cyclic voltammetry. Scanning electron microscope and electrochemical measurements were used to characterize the polyaniline-modified sensor surface. Electrochemical impedance spectroscopy (EIS) was finally used to determinate the variation of pH in [Fe(CN)6]3−/4− solutions.

Blood Lead Levels and Associated Sociodemographic Factors among Children Aged 3 to 14 Years Living near Zinc and Lead Mines in Two Provinces in Vietnam.

Abstract: Lead poisoning in children is a major public health concern worldwide, especially in developing countries. We conducted a cross-sectional study on 403 children aged from 3 to 14 years living nearly zinc-lead mining areas in two provinces in Vietnam (Bac Kan and Thai Nguyen) from 06/2016 to 10/2016 to identify risk factors for lead contamination. Results. The proportion of children with blood lead levels (BLLs) ≥ 10 μg/dL was 80.51% in Bac Kan and 50% in Thai Nguyen; the mean blood lead level for children was 14.41 ± 9.42 μg/dL. In linear regression analyses, the body mass index was negatively associated with elevated BLLs with r = -0.404, p < 0.05 (95% CI: -0.801, -0.006). In multivariable regression analysis, several risk factors were associated with lead contamination including male sex (aOR = 2.44, 95% CI: 1.13-5.24, p = 0.02), play areas in Bac Kan (aOR = 2.3 (1.02-5.17), p = 0.04), proximity of children's home of less than 2 kilometers from the mine (aOR = 2.90 (1.54-5.44), p = 0.001), and inattentive symptoms in Thai Nguyen (aOR = 7.85, 95% CI 3.49-17.69, p = 0.001). Environmental factors, including lead concentrations in the soil and ambient air samples in both locations, are many times higher than Vietnamese standards.

First trimester fetal heart evaluation. A pictorial essay.

Abstract: Classically fetal heart evaluation is mandatory in the second trimester of pregnancy. Recent data suggest that the diagnosis of congenital heart disease is feasible in the first trimester (FT) of pregnancy, especially for trained examiners. In this pictorial essay we aim to illustrate in detail the particularity of the FT heart evaluation: the specific ultrasound techniques including practical tips for the basic and extended first trimester fetal heart evaluation protocol. The diagnosis is possible by the use of a variety of ultrasound techniques (B mode, CFM, Bidirectional Doppler, STIC, TUI) using the transabdominal/transvaginal probes. An abnormal FT heart scan requires second trimester reassessment. Unfortunately, not all cardiac disease can be potentially diagnosed in the first trimester. Based on their own experience the authors recommend that heart examination in the FT should be attempted in all fetuses, even in low risk pregnancies, using at least the basic Doppler examination protocol.

The Relationship Between Infant Methemoglobinemia and Environmental Exposure to Nitrates

Abstract: In the framework of the paper the incidence of infant methemoglobinemia in Cluj county, Romania was evaluated from medical records. The incidence rate ranged from 42 to 239 per 100,000 live births between 2000 and 2004. Bottle-babies less than 4 months are the age group most at risk of acquired methemoglobinemia. Well water was the main source of nitrate, though early incorporation of vegetable juices and table food into infant diet were also incriminated. Some recommendations for the management of methemoglobinemia in this area are described: introduce a low nitrate water supply scheme specially for infant feeding, education program for mothers to increase duration of breast feeding, further studies on long-term development effects on infants.
