Amoxicillin (AMX) is one of the antibiotics in the penicillin category that is used in various fields. Considering the harmful effects of its remains, it is necessary to survey the ways to remove this compound. Advanced oxidation process (AOPs), specially photo-Fenton has been used for the removal of AMX. This study has been conducted based on PubMed, Google Scholar, DOAJ, Web of Science, and Scopus databases during the years 2008-2019. Some factors such as the aquatic solution, light source characteristics, iron, and H2O2 concentration, AMX degradation percentage, removal of total organic carbon percentage, and AMX concentration have been surveyed to optimize the process. Studies showed that the photo-Fenton process is highly dependent on pH, and in most studies, the highest efficiency has been observed in acidic pH values. Using a more energy light source can be effective in reducing the use of catalysts and oxidizers. The combined methods of AOPs such as photo-Fenton, electro-Fenton, and photo-electro-Fenton have higher efficiency in increasing mineralization than the photon process. The use of synthetic wastewater has a higher efficiency in the degradation of AMX than in real wastewater in the photo-Fenton process, which can be due to the absence of the interfering agents in synthetic environments.
阿莫西林(AMX)是青霉素类抗生素中的一种,广泛应用于各个领域。考虑到其残留的有害影响,有必要研究去除该化合物的方法。高级氧化法(AOPs),特别是光fenton法已被用于AMX的去除。本研究基于2008-2019年间的PubMed、Google Scholar、DOAJ、Web of Science和Scopus数据库进行。考察了水溶液、光源特性、铁、H2O2浓度、AMX降解率、总有机碳去除率、AMX浓度等因素,对工艺进行了优化。研究表明,光- fenton工艺高度依赖于pH值,在大多数研究中,在酸性pH值下观察到最高的效率。使用能量更高的光源可以有效地减少催化剂和氧化剂的使用。光- fenton、电- fenton、光电- fenton等AOPs组合方法在增加矿化方面比光子方法效率更高。在光- fenton工艺中,使用合成废水对AMX的降解效率高于使用真实废水,这可能是由于合成环境中没有干扰剂。

Medical waste status is a severe public health problem worldwide. Proper medical waste management is of paramount importance. However, there is insufficient information about medical waste management and lack of management in different countries. The aim of this research was to investigate and evaluate the present status of medical waste management in different countries. We systematically searched Embase, PubMed/MEDLINE, Scopus, PubMed Central, Google Scholar databases, as well as medRxiv using the following keywords: medical waste, waste management, disposal, healthcare per-capita generation, gross domestic product (GDP), and hospital. A total of 38 eligible articles were identified. Correlations were calculated between the amount of medical waste generated (kg bed.day-1) vs. GDP per capita ($) and ranking of healthcare system performance. A negative correlation was found between medical waste generation rate and ranking of healthcare system performance. According to the findings of this study, the medical waste generation rate in different countries ranged from 0.14 to 6.10 kg bed.day-1. About 25% of countries segregated medical waste, and about 17% used standard storage for all medical waste. Shortcomings were also found in waste collection, storage, transportation and transfer, and disposal of medical waste management activities in different countries. Only about 25% of countries simultaneously used three techniques, such as autoclaving, incineration, and landfill for disposal and treatment of medical waste, and 91% used incineration method. This study highlights an essential need for particular medical waste management guidelines and regulations, technologies, knowledge and financing to upgrade medical waste management worldwide. This study can be considered to be a good guide for further research on medical waste management in developing and developed countries.
医疗废物状况是世界范围内一个严重的公共卫生问题。适当的医疗废物管理至关重要。然而,关于医疗废物管理的信息不足,而且不同国家缺乏管理。本研究的目的是调查和评估不同国家医疗废物管理的现状。我们系统地检索了Embase、PubMed/MEDLINE、Scopus、PubMed Central、Google Scholar数据库以及medRxiv数据库,使用以下关键词:医疗废物、废物管理、处置、人均医疗产出、国内生产总值(GDP)和医院。总共确定了38个符合条件的条目。计算了医疗废物产生量(kg beds .day-1)与人均GDP($)和医疗保健系统绩效排名之间的相关性。医疗废弃物产生率与医疗系统绩效排名呈负相关。根据本研究结果,不同国家的医疗废物产生率在0.14 - 6.10 kg / d -1之间。约25%的国家对医疗废物进行分类,约17%的国家对所有医疗废物采用标准储存。不同国家在废物收集、储存、运输和转移以及处置医疗废物管理活动方面也存在不足。只有约25%的国家同时使用高压灭菌、焚烧和填埋等三种技术处置和处理医疗废物,91%的国家使用焚烧法。这项研究强调,迫切需要制定特定的医疗废物管理准则和法规、技术、知识和资金,以提升全球医疗废物管理水平。本研究可为发展中国家和发达国家医疗废物管理的进一步研究提供良好的指导。

A previously healthy worker developed symptoms assigned to electromagnetic hypersensitivity (EHS) after moving to an office with exposure to high levels of anthropogenic electromagnetic fields (EMFs). These symptoms consisted of e.g. headache, arthralgia, tinnitus, dizziness, memory loss, fatique, insomnia, transitory cardiovascular abnormalities, and skin lesions. Most of the symptoms were alleviated after 2 weeks sick leave. The highest radiofrequency (RF) field level at the working place was 1.72 V/m (7,852 μW/m2). Maximum value for extremely low frequency electromagnetic field (ELF-EMF) from electric power at 50 Hz was measured to 285 nT (mean 241 nT). For electric train ELF-EMF at 16.7 Hz was measured to 383 nT (mean 76 nT). Exposure to EMFs at the working place could be the cause for developing EHS related symptoms. The association was strengthened by the symptom reduction outside the working place.

Lead is an environmental hazard; even small elevations in blood lead level can cause serious negative health effects in children, including irreversible impacts such as learning difficulties, attention disorders, and behavioral issues. Previous research has shown that some groups are at higher risk for lead poisoning including racial/ethnic minorities, those with low economic status, and immigrants, especially refugees. This systematic review explores recent literature studying disparities in lead poisoning in refugee children. Search terms were chosen with the assistance of a medical librarian, and two independent reviewers assessed articles using a PICOS criteria (Population, Intervention, Comparison, Outcome, Study Design) following the Preferred Reporting Items for Systematic review and Meta-Analysis Protocols (PRIMSA-P) guidelines, a set of evidence-based minimum standards for reporting in systematic reviews. 321 article titles were reviewed, 61 abstracts screened, and 17 methods sections reviewed, ultimately including 13 studies. The studies found a high prevalence of elevated blood lead level among refugee populations when compared to reference populations. Both pre-migration and post-migration factors were identified as contributors to the disparity, and associations were identified between elevated blood lead levels and factors such as country of origin, age, and other health variables. Health providers and resettlement workers should be aware of these disparities and related factors. Testing, care, education and consistent follow-up should be provided.

Most agricultural products are exposed to pesticides. Organochlorine (OCPs) insecticides have been banned for years due to their persistence in the environment and lipophilic properties. On the other hand, some carcinogenic organophosphates are used in high amounts. Therefore, this systematic review was performed with the keywords; pesticide, carcinogenic, carcinogen, residue, contamination, pollution, and food to determine the type of food and pesticide. 663 manuscripts were found by searching in databases. After initial screening and quality assessment of full text, 26 manuscripts were selected. In this study, by reviewing selected manuscripts, about 13 pesticides were associated with carcinogenic effects. These pesticides were Chlorothalonil, Glyphosate, Tetrachlorvinphos, Parathion, Malathion, Diazinon, heptachlor, Hexachlorobenzene, aldrin, dieldrin, DDT, chlordane, Lindane. Most of these pesticides were organochlorine. The organochlorine pesticides are primarily detected in foods of animal origin. In some studies, the amount of carcinogenic organochlorine was higher than the permissible levels. From the carcinogenic herbicide, Glyphosate. An important finding of this systematic review is that carcinogenic organochlorines are still a threat to cancer incidence.

The presence of trace elements such as lithium (Li) in water resources in the long term can endanger consumers' health. Several studies have been conducted on Li concentration in water sources; hence, this study attempted to retrieve studies using a systematic search. The search was conducted in Web of Sciences, Embase, PubMed, and Scopus databases from 1 January 2010 to 15 January 2023. Li concentration was meta-analyzed based on the type of water resources and countries subgroups in the random effects model (REM) statistical analysis. In addition, health risk assessment in different age groups was calculated using the target hazard quotient (THQ). This study included 76 papers with 157 data reports in our meta-analysis. The overall pooled concentration of Li was 5.374 (95 % CI: 5.261-5.487 μg/L). The pooled concentration of Li in groundwater (40.407 μg/L) was 14.53 times surface water (2.785 μg/L). The highest water Li content was attributed to Mexico (2,209.05 μg/L), Bolivia (1,444.05 μg/L), Iraq (1,350 μg/L), and Argentina (516.39 μg/L). At the same time, the lowest water Li content was associated with Morocco (1.20 μg/L), Spain (0.46 μg/L), and India (0.13 μg/L). THQ due to Li in water resources in consumers of Iraq, Mexico, South Africa, Afghanistan, Bolivia, Portugal, Malawi, South Korea, Nepal, South Korea, Argentina, and the USA was higher than 1 value. Therefore, continuous monitoring of Li concentration in water sources and reducing Li concentration, especially in groundwater water, using new water treatment processes in these countries are recommended.

Polycystic ovary syndrome (PCOS) is one of the most common endocrine disorders. This abnormality is identified with hyperandrogenism, polycystic ovary and ovulation disorder. Environmental factors are one of the etiologies of this disease. In this systematic review, a search was performed with the keywords of polycystic ovary syndrome, PCOS, pesticides, organochlorine, heavy metals, PCBs, PAHs, bisphenol A, BPA, phthalates, mycotoxin, Tributyltin, TBT, environmental contaminants, regardless of publication time. 567 studies were obtained and after assessing 26 articles were finally selected. 61 % of the studies were attributed to bisphenol A. The positive correlation was seen between bisphenol A, tributyltin, air pollutants and organic contaminates with this disease. The association between this syndrome and bisphenol A in adolescents was also confirmed. Zinc has led to a reduction in the incidence of disease in almost all research literature. This issue can be considered in the prevention of the disease.

Objectives: The association between screen time and attention deficit hyperactivity disorder (ADHD) has been controversial. This study sheds light on the contentious correlation between screen time and ADHD.
Content: Until August 2022, electronic searches of the PubMed, Embase, and Web of Science databases were carried out. The combined effect value odds ratios (OR) and 95 % confidence interval (95 % CI) were calculated for the meta-analysis using Stata 12.0. There were 81,234 children in the nine studies that made up this meta-analysis which included 28,997 children with ADHD and 52,237 healthy controls. When compared with the screen time <2 h/d, the OR (95 % CI) value of screen time and ADHD in the screen time ≥2 h/d group was 1.51 (1.20-1.90).
Summary and outlook: Based on the current meta-analysis results, our study found a positive correlation between screen time and the risk of ADHD. Excessive screen exposure may significantly contribute to the development of ADHD in children. Therefore, it is necessary to reduce screen time per day in children to prevent the occurrence of ADHD.
目的:屏幕时间与注意缺陷多动障碍(ADHD)之间的关系一直存在争议。这项研究揭示了屏幕时间与多动症之间有争议的相关性。内容:直到2022年8月,PubMed, Embase和Web of Science数据库的电子搜索都在进行。使用Stata 12.0计算meta分析的综合效应值优势比(OR)和95 %置信区间(95 % CI)。在这项荟萃分析的9项研究中,有81234名儿童参与,其中包括28997名多动症儿童和52237名健康对照。总结与展望:根据目前的荟萃分析结果,我们的研究发现屏幕时间与ADHD风险呈正相关。过度的屏幕暴露可能会显著促进儿童多动症的发展。因此,有必要减少儿童每天的屏幕时间,以防止ADHD的发生。

Particulate matter (PM) is considered an intrauterine toxin that can cross the blood-placental barrier and circulate in fetal blood, affecting fetal development, and implicating placental and intrauterine inflammation, and oxidative damage. However, the relationship between PM exposure and adverse pregnancy outcomes is still unclear and our aim was to systematically review toxicological evidence on the link between PM exposure during pregnancy and the development of gestational diabetes mellitus or hypertensive disorders of pregnancy, including gestational hypertension and pre-eclampsia. PubMed and Science Direct were searched until January 2022. Of the 204 studies identified, 168 were excluded. The remaining articles were assessed in full-text, and after evaluation, 27 were included in the review. Most of the studies showed an association between PM exposure and gestational hypertension, systolic and diastolic blood pressure, pre-eclampsia, and gestational diabetes mellitus. These results should be interpreted with caution due to the heterogeneity of baseline concentrations, which ranged from 3.3 μg/m3 to 85.9 μg/m3 and from 21.8 μg/m3 to 92.2 μg/m3, respectively for PM2.5 and PM10. Moreover, critical exposure periods were not consistent among studies, with five out of ten observational studies reporting the second trimester as the critical period for hypertensive disorders of pregnancy, and ten out of twelve observational studies reporting the first or second trimester as the critical period for gestational diabetes mellitus. Overall, the findings support an association between PM exposure during pregnancy and adverse pregnancy outcomes, highlighting the need for further research to identify the critical exposure periods and underlying mechanisms.
