Systematic Identification

Lead readily crosses the placenta and displays adverse effects on birth outcomes and neurodevelopment. Systematic identification of the risk of exposure during pregnancy is essential but rarely performed, probably due to hospital staff’s workload and their lack of awareness. We aimed to evaluate the relevance of a questionnaire to screen pregnant women for lead exposure. A cross-sectional, multicentre study was carried out on a population of 792 pregnant women from February 2018 to May 2020. A total of 596 women had a blood lead test: 68.5% had blood lead levels below 10 μg/L. The estimated prevalence above 25 µg/L was 4% (95% confidence interval (CI) [2.6–5.9]) and 1.3% had levels above 50 µg/L (95% CI [0.6–2.6]). Multivariate analysis showed that three risk factors significantly increased the probability of blood lead levels above 25 µg/L: the use of traditional cosmetics (adjusted odds ratio [aOR]: 3.90; 95% CI [1.65–9.21]; p = 0.002), degraded old housing (aOR: 2.67; 95% CI [1.19–6.038]; p = 0.018), and (marginally) eating bread more than twice a day (aOR: 2.40; 95% CI [0.96–6.11]; p = 0.060). Our study reveals that a three-question tool can be used to quickly screen for the risk of lead exposure in our population and to trigger lead blood tests and special vigilance during pregnancy follow-up.

Background: Lead has no advantage for health, pregnant women are vulnerable to lead exposure. Blood Lead Levels (BLLs) in pregnant women that exceed the quality standard in accordance with Center for Disease Control (CDC) (>5 μg/dL) can encounter spontaneous miscarriage and fatigue easily during pregnancy, BLLs in pregnant women < 10 μg/dL can induce health problem during pregnancy such as hypertension, preeclampsia, and eclampsia which is the cause of mortality in pregnant women and high maternal mortality. The aim of study to measure BBLs and the source of exposure.Methods: Pregnant women in 2nd and 3rd trimester were recruited in 4 Subdistricts. Cross sectional study is used with 86 pregnant women located in Wanasari Subdistrict, Bulakamba Subdistrict, Losari Subdistrict and Tanjung Subdistrict with purposive sampling method. BLLs during pregnancy were determined by Atomic Adsorpiton Spectrometer.Results: The results shows that mean of BLLs in pregnant women in this study were 42.437 + 19.758 μg/dL. The source of lead exposure are the habit of consuming seafood (44.2%), wrapping food using newspaper (80.2%), being involve in agricultural activity (37.2%), and passive smoking (70.9%).Conclusions: To recapitulate, BBLs in pregnant women in the northern area of Brebes Regency have exceeded the standard set by the CDC of 5 μg/dL. The dominant source of lead exposure are the habit of wrapping food using newspaper and passive smoking.

Abstract Background Removing lead sources is the main measure against child lead poisoning. Medical treatment is ineffective for most mild cases and particularly against long-term complications in neurological development. However, the effectiveness of interventions to eliminate sources of lead exposure has not been fully established, mainly because of the diversity of situations. The objective of this study was to determine the influence of several interventions (housing counselling, rehabilitation and relocation) on blood lead levels in two situations (stable unhealthy housing with old flaked lead paints, slums with family recycling practices by incineration). Methodology A historical cohort of lead poisoning in children has been established in Marseille, France. Medical follow-up followed national guidelines. Environmental interventions followed legal procedures, where available. In slums, counselling was adapted to the exposure. A generalized mixed model was developed to study the kinetics of blood lead levels after the interventions. Results 151 children were included; age = 5.4 (SD = 7.8) years; 85 (56%) lived in stable unhealthy housing, others lived in slums. Medical follow-up included 492 blood lead levels. For children living in stable unhealthy housing, blood lead level decrease was significantly associated with every intervention: housing counselling, rehabilitation and relocation (respectively p &lt; 0.005; p &lt; 0.05 and p &lt; 0.005). For children living in slums, blood lead level decrease was only associated with relocation in a stable housing (p &lt; 0.005). Conclusions Several interventions are effective to decrease blood lead levels in unhealthy housing. In slums, access to a stable housing first is a prerequisite for any intervention against child lead poisoning, even when related to family practices. Key messages In stable unhealthy housing, several interventions against lead exposure can be effective to raise a strategy. But, environmental health and access to housing first needs to be addressed for their implementation.

Background: Lead is a toxic metal that can be contained in paint as a source of lead exposure in the air so significantly associated with blood lead levels (BLL). Statistically there is a significant association between BLL and blood pressure (BP). Preliminary study found that 10 workers of Carroseri Semarang found that 8 people (80%) had BLL above the threshold value, 7 people (70%) had a systolic blood pressure (SBP) above the limit normal and 8 people (80%) had diastolic blood pressure (DBP) at the upper limit of normal.Objective: This study aimed to determine the association between BLL and BP workers of Carroseri Semarang.Methods: It was an observational study with cross sectional approach. The population of this research was workers of Carroseri Semarang with a sample size of 34 people. Data collected by examining the levels of lead in paint, inspection level of lead in the air, checking blood lead levels and blood pressure checks.Results: This study showed the average level of lead in the paint measured was 59.39 ppm, level of lead in the air 0.002 ppm, BLL 28.97 mg/dL, SBP 122.76 mmHg and DBP 79.06 mmHg.Conclusion: All types of paint used in Carroseri Semarang contain lead under TLVs 600 ppm, the ambient workspace containing air lead levels below TLVs 0.05 ppm, the entire workforce part painting has undergone blood lead exposure >5μg/dL, there is no association between BLL and SBP (p=0.465) and there a association between BLL and DBP (p =0.030).

Abstract Background Pruritus is a common and often distressing symptom in patients with chronic kidney disease. Though the pathogenesis of uremic pruritus remains poorly understood, systemic inflammation has presented itself as one of the possible explanations. High blood lead levels (BLLs) have been noted to be associated with inflammation and poor nutritional status in hemodialysis patients. Our aim is to study the relation between blood lead levels and uremic pruritus. This is a cross-sectional study that enrolled 50 patients; all were on regular hemodialysis 3 times per week for at least 6 months. Patients were divided into 2 groups, group 1 (n =10) with no pruritus and group 2 (n=40) with varying degrees of pruritus. Group 2 was further divided according to intensity of pruritus by visual analog score (VAS) into mild (n=10), moderate (n=20), and severe pruritus (n=10). Results There was a significant difference in serum lead levels and ferritin levels between groups 1 and 2 (p value < 0.01 and < 0.05, respectively). There was a statistically significant difference in serum lead levels in the groups with varying intensity of pruritus, having higher serum lead levels in patients who exhibited severe pruritus (p value < 0.005) Moreover, a statistically significant relation between elevated blood lead levels and the duration of dialysis was observed in this study. Conclusion Uremic pruritus is a multi-factorial phenomenon, and our study showed that blood lead levels in hemodialysis patients might be associated with increased intensity of pruritus.

AbstractLead is a heavy metal without a biological role. High level of lead exposure is known to be associated with hypertension, but the risk at low levels of exposure is uncertain. In this study, data from US NHANES 1999–2016 were analyzed. Adults with blood lead and blood pressure measurements, or self-reported hypertension diagnosis, were included. If not already diagnosed, hypertension was defined according to the AHA/ACC 2017 hypertension guideline. Results were analyzed using R statistics version 3.5.1 with sample weight adjustment. Logistic regression was used to study the association between blood lead level and hypertension. Odds ratio (OR) and 95% confidence interval (95% CI) were estimated. Altogether, 39,477 participants were included. Every doubling in blood lead level was associated with hypertension (OR [95%CI] 1.45 [1.40–1.50]), which remained significant after adjusting for demographics. Using quartile 1 as reference, higher blood lead levels were associated with increased adjusted odds of hypertension (Quartile 4 vs. Quartile 1: 1.22 [1.09–1.36]; Quartile 3 vs. Quartile 1: 1.15 [1.04–1.28]; Quartile 2 vs. Quartile 1: 1.14 [1.05–1.25]). In conclusion, blood lead level is associated with hypertension in the general population with blood lead levels below 5 µg/dL. Our findings suggest that reducing present levels of environmental lead exposure may bring cardiovascular benefits by reducing blood pressure.
