Cadmium Level Status in Iranian Breast Milk: A Systematic Review

Introduction: Due to the lack of a systematic review on cadmium status in breast milk of Iranian mothers, this study was designed to evaluate the published articles on factors affecting the exposure and the levels of cadmium in breast milk. Methods: In this study, English and Farsi electronic databases, including PubMed, Scopus, Google Scholar, Web of Science, Magiran, Iran Medex and SID were comprehensively searched for papers published from July 2009 until May 2021. The PRISMA guidelines for reporting systematic reviews were followed for screening and reviewing the processes involved in this study. Results: From 102 articles found in the initial search, 9 studies were included in systematic review. The highest mean cadmium concentration was related to milk samples collected from Kerman City. Among study factors, the exposure to cigarette smoke, living near industrial centers and maternal nutrition had a significant effect on increasing the concentration of cadmium in breast milk. Conclusion: Further studies are demanded to obtain more comprehensive and reliable results on the status of cadmium in breast milk of Iranian mothers.

Health effects of selected trace elements in hairdressing cosmetics on hairdressers in Enugu, Nigeria

Could trace elements in hairdressing cosmetics prove carcinogenic to hairdressers, who use them regularly as raw materials in hairdressing business? The toxic effects of selected trace elements contained in hairdressing cosmetics on hairdressers were investigated by regressing the quality of life values for hairdressers with their blood/urine levels of the toxic metals A hundred subjects were randomly drawn from a cluster of hairdressers. Blood lead level, 17.47 ± 4.59 µg/dL, confirmed that the hairdressers were regularly exposed to lead. Mean blood mercury level, 25.06 ± 4.11 ng/dL, was above the normal blood mercury concentration of less than 10–20 ng/mL. Mean blood cadmium level, 3.64 ± 1.87 µg/dL, was within the normal range, < 5.0 µg/dL. Mean urine arsenic level, 96.16 ± 38.34 µg/L, was above normal range, ≤ 50 μg/dL, but within high normal range, > 50 to < 200 μg/dL. Blood nickel level, 0.49 ± 0.20 µg/dL, was above both the healthy range, 0.14–0.65 µg/dL, and the most reliable value of 0.2 µg/dL. Negative correlations existed between the quality of life and levels for lead (R = − .017), mercury (R = − .008), arsenic (R = − .072) and nickel (R = − .168), but there was positive correlation with cadmium level (R = .123). At 0.096, the probability value (p value) for nickel was significant at 10%. P value as insignificant at 1%, 5% and 10% for lead (0.868), mercury (0.940), cadmium (0.224) and arsenic (0.475). Therefore, Ni contained in hairdressing cosmetics might have carcinogenic effects that affected the quality of life of hairdressers, unlike other trace elements tested, namely, lead, mercury, cadmium and arsenic. Further research with the tumor markers assessment is recommended to confirm the carcinogenic effect of Ni.

MPDB 2.0: a large scale and integrated medicinal plant database of Bangladesh

Objective MPDB 2.0 is built to be the continuation of MPDB 1.0, to serve as a more comprehensive data repertoire for Bangladeshi medicinal plants, and to provide a user-friendly interface for researchers, health practitioners, drug developers, and students who wish to study the various medicinal & nutritive plants scattered around Bangladesh and the underlying phytochemicals contributing to their efficacy in Bangladeshi folk medicine. Results MPDB 2.0 database (https://www.medicinalplantbd.com/) comprises a collection of more than five hundred Bangladeshi medicinal plants, alongside a record of their corresponding scientific, family, and local names together with their utilized parts, information regarding ailments, active compounds, and PubMed ID of related publications. While medicinal plants are not limited to the borders of any country, Bangladesh and its Southeast Asian neighbors do boast a huge collection of potent medicinal plants with considerable folk-medicinal history compared to most other countries in the world. Development of MPDB 2.0 has been highly focused upon human diseases, albeit many of the plants indexed here can serve in developing biofuel (e.g.: Jatropha curcas used in biofuel) or bioremediation technologies (e.g.: Amaranthus cruentus helps to reduce cadmium level in soil) or nutritive diets (Terminalia chebula can be used in nutritive diets) or cosmetics (Aloe vera used in cosmetics), etc.

Assessment of selected heavy metal load and identification of bacterial status associated with suya meat sold in Anambra state, Nigeria

Heavy metals and some pathogenic bacteria tend to contaminate food substances commonly consumed and this pose as health risks to the populace. The study was therefore conducted to assess the level of metal and bacteria contamination of meat barbecue (SUYA) commonly consumed in Anambra State, Nigeria. Thirty six sample were evenly collected from the sensational Zones and analyzed using Atomic Absorption Spectrophotometer. Metal values obtained range as follows: Cadmium(4.17-7.93mg/kg), Lead(0.24-3.39mg/kg),Zinc(2.6-28.3mg/kg) and Arsenic(0.19-2.3mg/kg). Samples from Anambra North had the highest Zinc, Lead, and Arsenic levels 14.02, 0.94, and 0.96mg/kg rewspectively, while Anambra South recorded the highest cadmium level 6.16mg/kg. The Estimated daily intake(EDI) of Cadmium alone was found to be greater than the recommended value in the 3 senatorial zones. Again only Cadmium had a target hazard quotient(THQ) of greater than one in all the senatorial zones. All the zones had hazard index (HI) greater than one. North(5.95+00). South,(8.1E+00) and Central(4.8+00). Cancer risk for cadmium recorded in all the zones were above accepted limits. While for Arsenic the North zone recorded levels above acceptable limits. The following bacteria species were isolated from analyze soya samples. Staphyloccocus cereus, Bacillus aureus, Salmonella species, Pseudomonas aeruginosa, Klebsiella pneumonia,however bacillus cereus was most commonly isolated and Pseudomonas aeruginosa least commonly isolated. The results indicated an appreciable level of contamination and a possible public health risk.
