From a broad view, modern human complex diseases, such as cardiovascular disease, metabolic disorders, neurodegenerative disease, and cancer, are environmental diseases.[1] Notably, disruption or dysregulation of immunity and/or metabolism are the major events that drive the pathogenesis of environmental complex diseases. This has been consolidated by overwhelming evidence provided by the biomedical research community over the past decades. Among the signaling pathways that drive immune response and metabolic changes, intracellular organelle stress responses, particularly stress signaling originated from the endoplasmic reticulum (ER) and mitochondria, play major roles in the development of inflammatory metabolic diseases or environmental diseases.[1,2] In the past decades, a large number of original research and review articles on this topic have been published. However, an important but perplex question remains: is ER or mitochondrial stress response protective or detrimental to the development of environmental complex diseases, such as atherosclerosis, type 2 diabetes mellitus, and nonalcoholic fatty liver disease? This question is raised because a big body of works showed that ER stress response or mitochondria-originated oxidative stress response contributes to or exacerbates cardiovascular and metabolic diseases, while many others observed that intracellular stress response is protective. Overviewing the literature, it becomes clear that cellular stress response, like a “double-edge” sword, plays both protective and harmful roles in the progression of inflammatory and metabolic diseases[1,3] [Figure 1]. As an indispensable defense response, the primary role of intracellular stress signaling or inflammatory response is protective, providing a survival mechanism to the stressed cells or complex organisms by helping them regain homeostasis and adapt to the stress conditions.[2,4,5] This is evidenced by the fact that major cell stress sensors are indispensable to cell physiology and survival. For example, the deficiency of the primary ER stress sensor inositol-requiring enzyme 1α (IRE1α) or PRKR-like endoplasmic reticulum kinase (PERK) leads to embryonic lethality.[6–8] Hepatic IRE1α-mediated stress signaling is required to prevent stress-induced fatty liver disease.[9,10] The liver-enriched cell stress senor CREBH functions as a major metabolic regulator of lipid and glucose metabolism in response to hepatic stress or energy demands.[11–14] The neuronal astrocyte-specific ER stress sensor old astrocyte specifically-induced substance (OASIS) is required to protect astrocytes from ER stress-induced cell death.[15,16] In addition, SMAD3-TGFβ inflammatory stress signaling plays a critical role in protecting blood vessel wall integrity.[17] Exp","PeriodicalId":11702,"journal":{"name":"Environmental Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136004855","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional medicine is accepted in Nigeria for its effectiveness. The plant’s various parts treat fever, malaria, diabetes, ulcers, and gonorrhea. It contains alkaloids, anthraquinones, anthraquinols, steroids, terpenoids, tannins, saponins, flavonoids, phenols, and glycosides. Objective: This study aimed to investigate the inflammatory response in P. falciparum-infected patients treated with the raw liquid extract of M. lucida leaves in traditional homes in Nigeria. Materials and Methods: The study was conducted in ten traditional homes in Saki, Nigeria. Fifty P. falciparum-infected participants receiving treatment in traditional homes were recruited, along with 50 participants receiving conventional malaria treatment in hospitals and 50 noninfected participants as controls. Blood samples were collected for the estimation of parasite density by microscopy, plasma interleukin-10 (IL-10), and tumor necrosis factor-alpha (TNF-α) levels by ELISA. The raw liquid extract of M. lucida leaves was prepared and administered to the patients. Statistical analysis was performed to compare the results among the different groups. Results: The results showed a significant difference in plasma IL-10, TNF-α levels, and parasite density across the different groups. Treatment with the raw liquid extract led to a decrease in plasma IL-10 levels and an increase in plasma TNF-α levels and parasite density in the infected patients. No significant difference was observed between traditional home and hospital patients in terms of IL-10 levels and parasite density. Conclusion: The findings suggest that the raw liquid extract of M. lucida leaves may modulate the inflammatory response in P. falciparum-infected patients. Further studies are needed to explore the therapeutic potential of this plant in the treatment of malaria.","PeriodicalId":11702,"journal":{"name":"Environmental Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136004854","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While sources such as judicial proceedings, scientific literature, social media, and Internet websites report that some neighbors contemplate leaving their homes, research on this topic is limited. This study continues to explore why they contemplated such a housing decision. Methodology: The ethics-reviewed study used the qualitative Grounded Theory (GT) methodology and interviewed 67 consenting participants, 18 years or older, who had previously lived, or were currently living, within 10 km of IWTs. Audio files were transcribed to text and the data were coded and analyzed using NVivo Pro (v. 12.6) software. Objectives: The objective of this manuscript is to explore participants’ descriptions of their medical diagnoses provided by their physicians and physician specialists. Results: Data analysis revealed primary and subthemes associated with environmental interference and altered living conditions. Of the 67 participants, eight described their diagnoses of medical conditions as given by their physicians and physician specialists. Descriptions of conversations with participants’ health-care providers were also surveyed. Discussion: Medical diagnoses, descriptions of comments by health practitioners and the commonality of globally reported adverse health effects (AHEs), support the potential risk of locating IWTs near residential areas. It is recommended that members of the public, government authorities, policy makers, researchers, health practitioners, and social scientists with an interest in health policy and disease prevention acknowledge this risk and advocate for the immediate, effective, and timely resolution for affected neighbors. Conclusions: The GT methodology was used to develop a substantive theory regarding the housing decisions of participants living within 10 km of a Wind Power Plant. Results from the interviews indicate that these decisions were motivated by the potential for, or the experience of, AHEs which they attributed to living in proximity to these installations.","PeriodicalId":11702,"journal":{"name":"Environmental Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136004876","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The etiology of uterine fibroids and the mechanisms of their growth are not fully understood, and those factors that make women to be susceptible to fibroid development are subjects of investigation. Environmental toxicants such as toxic metals exposure have been implicated, but the results have not been consistent. This study seeks to determine the association between blood cadmium (Cd), arsenic (As), and lead (Pb) levels and the risk of uterine fibroids among women of reproductive age. Materials and Methods: This case–control study comprised 100 women of reproductive age (age range, 20–50 years) with uterine fibroid and 50 age-matched women without uterine fibroids. Fibroids were diagnosed using abdominal scan by attending physicians. Furthermore, the control subjects were screened for fibroids using abnormal scan. Blood Cd, As, and Pb were determined using an atomic absorption spectrophotometer, and the risk of association was calculated. Results: The mean blood Cd, As, and Pb were significantly higher (P < 0.001) among women with fibroid than those without fibroid (controls). The odds ratio for Cd 2.62 (confidence interval [CI]: 0.02–0.05), As 1.02 (CI: 0.02–0.030), and Pb 1.42 (CI: 0.04–0.129) was greater among women with uterine fibroids than controls. Conclusions: Exposure to cadmium and lead might be a risk factor for developing uterine fibroids among Nigerian women.","PeriodicalId":11702,"journal":{"name":"Environmental Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79813601","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A potentially significant implication may be due to hyperglycemia, found in one-third of all acute ischemic stroke (AIS) patients. However, prior studies reported conflicting information about the impact of hyperglycemia on poststroke prognosis, likely due to different measurements of stress-induced hyperglycemia. The glucose-to-glycated hemoglobin ratio is an index of stress-induced hyperglycemia after AIS that better quantifies acute changes in blood glucose, as opposed to absolute variations in glucose levels. Moderate blood glucose reductions might counteract the negative effects of hyperglycemia and glycemic control medications can also play a role in neuroprotection. The liver is the main organ that functions to maintain energy and glucose metabolism and the effects of AIS can reach far peripheral organs, including the liver. In this review, we highlighted the mechanism responsible for acute poststroke hyperglycemia, a hepatic inflammatory pathway that results in hepatic gluconeogenesis and reduced hepatic insulin sensitivity. Hepatitis cascades lead to hepatic gluconeogenesis, and targeted therapy with antihyperglycemic drugs has the potential to improve stroke prognosis and recovery.","PeriodicalId":11702,"journal":{"name":"Environmental Disease","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77631439","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Housekeeping staff members are directly involved in the collection, transport, and disposal of biomedical waste and are at high risk of acquiring infections. At the same time, they are usually unskilled, uneducated, and have little to no knowledge about the segregation and disposal of biomedical waste, which further compounds their health risk. Objective: To assess the awareness and practices regarding biomedical waste management in housekeeping staff of a tertiary care hospital. Subjects and Methods: A cross-sectional study was conducted among 100 housekeeping staff members of a tertiary teaching hospital in Pune, Maharashtra, from February to April 2022. A semi-structured, pretested questionnaire was used for data collection. Knowledge of the study participants was scored on a scale of 0–10 and the median score of all the study participants was taken as a cutoff for determining good and poor knowledge. The data were entered into MS Excel 2010 and analyzed using IBM SPSS software 16-trial version. The Chi-square test was used as a test of significance. Results: In the present study, 73% of study participants had good knowledge regarding biomedical waste management. All the participants (100%) were following appropriate practices regarding biomedical waste management.
