Manganese is essential for adequate feto-maternal health; however, an inverted U-shaped relation has been found between maternal manganese status and pregnancy complications. This systematic review summarizes the effect of maternal manganese exposure and perinatal health. We adopted a systematic approach to retrieve the recent literature. After applying the inclusion/exclusion criterion, a total of 20 studies were included in this review. Results found a non-significant relationship between maternal manganese exposure and risk of gestational diabetes mellitus (GDM), while only three studies reported the association between higher manganese levels and risk of preterm birth. Also, inconsistent results were found regarding higher manganese status and risk of low birth weight. This review reported no association between higher maternal manganese status andrisk of GDM. Nevertheless, the paucity of literature related to small for gestational age and pre-eclampsia prohibits a conclusion. Further studies are required for evaluation of environmental manganese exposure and maternal manganese status.

Swimming pools and jacuzzis can pose significant public health risks as potential sources of infections. The present study aimed to evaluate the prevalence and concentration of microbiological indicators in recreational water facilities in Thessaloniki, Northern Greece, focusing on their hygiene status before and after the COVID-19 pandemic. Between January 2018 and December 2022, 1114 water samples were analyzed by the regional Water Hygiene Laboratory at Aristotle University of Thessaloniki, using standardized ISO methods. Jacuzzis exhibited the highest microbial contamination, particularly for Pseudomonas aeruginosa (19.7%), while indoor adult pools showed the lowest. Overall, P. aeruginosa was found in 12.4% of samples, with the highest concentrations in jacuzzis (median: 30 CFU/100 ml). Significant seasonal variations were identified in the prevalence of total microbial flora (p < 0.001) and total coliforms (p = 0.03), as well as in the concentration of residual chlorine (p = 0.023). During the COVID-19 pandemic, microbial prevalence decreased across facilities. We concluded a strong compliance with Greek and international microbiological standards. The decline in microbial prevalence overtime likely reflects the impact of the strict hygiene measures implemented during the pandemic. These findings highlight the importance of maintaining rigorous hygiene practices to protect public health.

游泳池和按摩浴缸是潜在的传染源,会对公众健康造成重大威胁。本研究旨在评估希腊北部塞萨洛尼基市娱乐用水设施中微生物指标的流行率和浓度,重点关注 COVID-19 大流行前后这些设施的卫生状况。2018 年 1 月至 2022 年 12 月期间,塞萨洛尼基亚里士多德大学地区水卫生实验室采用 ISO 标准化方法对 1114 份水样进行了分析。按摩浴缸的微生物污染程度最高,尤其是铜绿假单胞菌(19.7%),而室内成人游泳池的微生物污染程度最低。总体而言,12.4%的样本中发现了铜绿假单胞菌,其中按摩浴缸中的铜绿假单胞菌浓度最高(中位数:30 CFU/100 ml)。在微生物菌群总数(P = 0.03)和余氯浓度(P = 0.023)方面发现了明显的季节性变化。在 COVID-19 大流行期间,各设施的微生物流行率均有所下降。我们得出结论,希腊和国际微生物标准得到了严格遵守。微生物流行率的下降可能反映了大流行期间实施的严格卫生措施的影响。这些发现强调了保持严格的卫生措施对保护公众健康的重要性。

This study explored the therapeutic potential hydroalcoholic extract derived from Origanum vulgare leaf in mitigating ethanol-induced working memory impairments and hippocampal oxidative stress in rats. Eight groups, including controls, ethanol-exposed rats, and those treated with extract (100, 200, and 300 mg/kg) alone or combined with ethanol, were assessed using the radial arm maze (RAM) for behavioral tests. Ethanol increased working memory errors and time spent in error zones, effects notably reduced by the extract, especially at 300 mg/kg dose (P≤0.001). Biochemical tests showed ethanol suppressed catalase (CAT), superoxide dismutase (SOD), and acetylcholinesterase (AChE) activities within the hippocampus and cortex. while the extract elevated CAT and SOD activities and reduced AChE activity. These results suggest the extract's neuroprotective properties, including oxidative stress reduction and neurotransmitter modulation, which mitigate ethanol-induced hippocampal damage. This highlights Origanum vulgare extract potential as a therapeutic adjunct for memory deficits and oxidative stress-related conditions.

本研究探讨了从牛至叶提取的水醇提取物在减轻乙醇引起的大鼠工作记忆损伤和海马氧化应激方面的治疗潜力。八组大鼠(包括对照组、乙醇暴露组、单独或与乙醇联合使用提取物(100、200 和 300 毫克/千克)治疗组)均接受了径向臂迷宫(RAM)行为测试评估。乙醇会增加工作记忆错误和在错误区花费的时间,提取物会明显减少这些影响,尤其是在 300 毫克/千克剂量时(P≤0.001)。生化测试表明,乙醇抑制了海马和大脑皮层中过氧化氢酶(CAT)、超氧化物歧化酶(SOD)和乙酰胆碱酯酶(AChE)的活性。这些结果表明,牛至提取物具有神经保护特性,包括减少氧化应激和调节神经递质,从而减轻乙醇诱导的海马损伤。这凸显了牛至提取物作为治疗记忆缺陷和氧化应激相关疾病的辅助药物的潜力。

Recently essential oils (EOs) encapsulation is experiencing growing applications in agricultural and agri-food sector. Encapsulation is reported as safe environmental technology leading to a reduction of conventional insecticides use. This study concerns the assessment of fumigant toxicity and persistence of Rosmarinus officinalis EO encapsulated in two cyclodextrins β-CD and HP-β-CD against larvae of the date moth, Ectomyelois ceratoniae. The retention capacity, encapsulation efficacy, loading capacity and release behavior of the two inclusion complexes were investigated. Results showed that two studied CDs had in important retention capacity. Additionally, the encapsulation within CDs delayed the release of rosemary EO bioactive components; which explains the effectiveness of the encapsulated rosemary EO in CDs against E. ceratoniae fifth instars larvae. Furthermore, the encapsulation in the two CDs improved the persistence of the insecticidal toxicity. This study supports the use of cyclodextrins, mainly HP-β-CD, in the date industry for the control of insect pests.

最近,精油(EOs)封装技术在农业和农业食品领域的应用越来越广泛。据报道,封装是一种安全的环保技术,可减少传统杀虫剂的使用。本研究评估了包裹在两种环糊精 β-CD 和 HP-β-CD 中的麝香石竹环氧乙烷对枣树夜蛾幼虫的熏蒸毒性和持久性。研究了两种包合复合物的保留能力、封装效果、负载能力和释放行为。结果表明,所研究的两种 CD 具有重要的保留能力。此外,包裹在 CD 中会延迟迷迭香环氧乙烷生物活性成分的释放,这就解释了包裹在 CD 中的迷迭香环氧乙烷对陶瓷虫第五龄幼虫的有效性。此外,在两种光盘中封装迷迭香环氧乙烷提高了杀虫毒性的持久性。这项研究支持在红枣产业中使用环糊精(主要是 HP-β-CD)来控制害虫。

Changsha, a city of 10 million people in China, has complex patterns of influenza activities. There is limited evidence on how temperature influences influenza activity across different populations in a subtropical region. We collected influenza surveillance data from all medical facilities in Changsha City from 2017 to 2023. The effects of temperature on various influenza indicators, including daily frequency of influenza, influenza-like illness (ILI) rate, influenza A (FluA) rate, and influenza B (FluB) rate, were assessed using the distributed lag nonlinear model. This study revealed temperature exhibited the most significant impact on influenza activity. The low temperature (below 10°C) increased the effect on all influenza indicators, while the high temperature (above 25°C) primarily enhanced the effect on FluA and ILI rates. The impact on populations aged 6-17 years was significantly stronger than on other groups. The research results could provide reference for influenza prediction and early warning.

Control measures for disinfectant pollution and related anthropogenic behaviors are required. Benzalkonium chloride (BAC) with widespread use especially in hand sanitization is highlighted as a representative disinfectant emerging contaminant. This cross-sectional survey was conducted to assess the knowledge, attitudes, practice regarding BAC use for hand hygiene among medical students from the perspective of environmental sustainability. Of the 703 responding students, only 3.7% had never used hand sanitizer products containing BAC. But few students paid attention to the "environmental friendliness" property of products when consumption. Mean knowledge test score was 1.90 out of 5, suggesting poor knowledge regarding BAC use. Most students had positive attitudes toward source control of BAC pollution and strong intentions to learn more about environmental knowledge related to BAC and other disinfectants. Data indicated that medical students had positive attitudes but lacked knowledge and practices towards eco-friendly disinfectant use, thus further training and practice standards are required.

This study explores the effect of climate factors on dengue incidence in Bangladesh and Singapore from 2000 to 2020. Various forecasting models, including Seasonal ARIMA, Poisson regression, artificial neural networks (ANN), support vector machines (SVM), and other statistical techniques, were applied to forecast dengue trends and generate future datasets. The results showed that Bangladesh has higher mean temperatures. The Poisson regression indicated that rainfall positively correlated with dengue cases in Bangladesh, while humidity and sunshine showed negative associations. In Singapore, temperature was positively associated with dengue cases, while rainfall and humidity had inverse relationships. ARIMA models predicted Singapore would experience the highest dengue cases by 2023. Based on the Root Mean Square Error (RMSE), the TBATS model was most accurate for predicting dengue cases in Bangladesh, while both ARIMA and TBATS models performed well in Singapore. This study provides valuable insights for policymakers in Singapore and Bangladesh to develop climate-based warning systems.

The objective of this study was to determine the presence of C. difficile in seafood, to identify the ribotype of isolates, to reveal the distribution of their toxinogenic genes and to evaluate the antibiotic susceptibility of C. difficile strains. For this purpose, a total of 755 seafood samples were analysed. Sixteen isolates were verified as C. difficile [14 (5.28%) bivalve molluscs and 2 (2.0%) shrimp] whereas none of the ribotypes detected were human pathogenic ribotypes. Among C. difficile isolates only one of the bivalve mollusc (RT003) was found to be toxigenic (A+B+CDT+) that had also toxin-producing ability. All isolates were sensitive to vancomycin and resistant to cefotaxime. Results of this study indicate that the rate of C. difficile in seafood is much lower than in meat or poultry products. However, consumption of raw or undercooked contaminated bivalve molluscs could be a potential source of C. difficile that may pose a risk to human health.

However, consumption of raw or undercooked contaminated bivalve molluscs could be a potential source of C. difficile that may pose a risk to human health.</p>","PeriodicalId":14039,"journal":{"name":"International Journal of Environmental Health Research","volume":" ","pages":"1-10"},"PeriodicalIF":2.2,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142800678","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study examined the potential of vanillic acid (VA) to protect against renal oxidative stress and inflammation caused by sodium arsenite (SA) in mice. Mice were assigned to five groups: control, VA (100 mg/kg), SA (50 ppm in drinking water for 8 weeks), and SA + VA (50 and 100 mg/kg orally in the 7th and 8th weeks). After the experiment was ended, the Mice were sacrificed and serum and renal tissue samples were collected for additional assessments. Treatment with VA suppressed SA-induced increase in blood urea nitrogen and creatinine in the serum. Furthermore, renal histological damage induced by SA administration was ameliorated with VA treatment. Also, the increase in the level of lipid peroxidation marker (thiobarbituric acid reactive substances) along with the reduction in total thiol levels and the diminished activities of antioxidant enzymes (catalase, superoxide dismutase, and glutathione peroxidase) in the renal tissue of SA-treated mice were effectively reversed following treatment with VA. The results exhibited that the VA-treated groups (50 and 100 mg/kg) mitigated the elevation of inflammatory markers in kidney tissue (tumor necrosis factor-α and nitric oxide) in SA-exposed mice. Our research findings indicate that VA could be a potential therapeutic agent for the management of SA-associated nephrotoxicity.

Naturally occurring radionuclides in soil, water, and plants, including spices, pose potential health risks. Given the widespread use of spices in culinary practices, it is crucial to assess the potential health risks associated with their natural radionuclides content. This study determines the activity concentrations of natural radionuclides in locally processed and imported spices from markets in Delta and Ogun States, Nigeria, using gamma spectrometry. Monte Carlo simulations estimated the probabilistic distribution of cancer risk over a lifetime of exposure. The results revealed significant variability in the activity concentrations of 40K, 226Ra, and 232Th among the spice samples. The mean committed effective doses due to ingestion were 10.56 µSv/y, 9.82 µSv/y, and 6.87 µSv/y for locally produced and imported spices, respectively. Both deterministic and probabilistic analyses show that the cancer risk values fall within the acceptable range of 10-6 to 10-4, indicating minimal risk from ingestion of natural radionuclides in spices.
