Abstract
The hallmark of aluminum phosphide (AlP) poisoning is heart failure in victims which is associated with reactive oxygen species (ROS), mitochondrial dysfunction, oxidative stress, alteration in antioxidant defense system and depletion of ATP in cardiomyocytes. In the present study, we hypothesized that the injection of isolated mitochondria into blood or mitochondrial transplantation can likely create a primary target for phosphine released from AlP and inhibit AlP-induced mortality and cardiotoxicity in rat. Male, Wistar, healthy and adult rats were randomly divided into 5 groups as control, AlP (12.5 mg/kg, orally), AlP + mitochondria (125 µg/kg), AlP + mitochondria (250 µg/kg) and mitochondria (250 µg/kg) alone. Functional and intact mitochondria isolated from rat heart and transplantation was carried out via tail vein, 30 min after exposure to AlP. Survival rate, histopathological alterations, cardiac biochemical markers, oxidative stress and mitochondrial toxicity parameters were monitored and analyzed during 30 days. We found that injection of healthy mitochondria into blood at concentrations of 125 and 250 125 µg/ml significantly increased the survival of rats up to 40% and 56.25% respectively, during 30 days. Moreover, we observed that mitochondria injection into blood decreased histopathological damages, cardiac biochemical markers, oxidative stress and mitochondrial toxicity parameters. To our knowledge, the current study is the first report in the literature that demonstrated good therapeutic effects of mitochondrial transplantation in AlP-induced mortality and cardiotoxicity. The findings of the present study suggests that injection of exogenous mitochondria into blood could be an effective therapeutic strategy in treating AlP poisoning.

Toxicol Res (Camb) 2024; 13:tfae053. [PMID: 38585338 PMCID: PMC10995503 DOI: 10.1093/toxres/tfae053] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Revised: 03/11/2024] [Accepted: 03/26/2024] [Indexed: 04/09/2024] Open
Abstract
BACKGROUND Poisoning-induced shock is a serious medical emergency with a high mortality rate. Hospitalized poisoned individuals experience multiple adverse cardiovascular events that could progress to cardiac arrest. This study was designed to compare the prognostic role of the admission shock index and plasma copeptin level in shocked poisoned patients and to evaluate their associations with initial patients' characteristics and outcomes. METHODS We conducted a prospective study on acutely poisoned adult patients. RESULTS A total of 41 patients were enrolled in the study. The mean age of all patients was 27.05 ± 10.99 years and most of the patients were females (n = 27, 66%). Pesticides were the most common type of poisoning (n = 18, 44%), followed by cardiovascular drugs (n = 12, 29.3%). Eleven (26.8%) patients died during the hospital stay length. The initial serum copeptin level and shock index could predict organ dysfunction indexed by sequential organ assessment score (SOFA) with area under the curve (AUCs) of 0.862 and 0.755, respectively. Initial serum copeptin and lactate levels, SOFA score, and their combination can strongly differentiate between survivors and non-survivors with an AUC of 0.944, 0.885, and 0.959, and 0.994, respectively. CONCLUSION We concluded that the shock index, serum lactate level, and SOFA score may help in risk stratifying patients and predicting outcomes in critically ill patients with poisoning-induced shock. Copeptin is superior to the shock index in predicting mortality among the studied patients. However, a combination of SOFA score, serum copeptin level, and serum lactate level can develop a more predominant prediction for overall clinical outcomes in these patients.

Abstract
Some studies suggested that gastrointestinal (GIT) decontamination with oil may improve the prognosis of patients who ingested aluminum phosphide (AlP). The aim of this study is to compare the efficacy and safety of gastric lavage with oil-based solutions to any method of gastric decontamination not using oils in patients presenting with acute AlP poisoning. The literature was searched for English-published randomized controlled trials (RCTs) from inception to 16 September 2023. The searched electronic databases included MEDLINE/PubMed, Cochrane Library, Web of Science, Egyptian Knowledge Bank, Scopus, and Google Scholar. Data were extracted and pooled by calculating the risk ratio (RR) for categorical outcomes and standardized mean difference (SMD) for numerical outcomes, with 95% confidence intervals (CI). Seven RCTs were included. Paraffin oil was significantly associated with a lower risk of mortality (RR = 0.59 [95% CI: 0.45, 0.76], p < .001), intubation (RR = 0.59 [95% CI: 0.46, 0.76], p < .001) and vasopressor need (RR = 0.71 [95% CI: 0.56, 0.91], p = .006). Survival time was significantly prolonged with paraffin oil (SMD = 0.72 [95% CI: 0.32, 1.13], p < .001). Coconut oil was significantly associated with prolonged survival time (SMD = 0.83 [95% CI: 0.06, 1.59], p = .03) as well as decreased risk of requiring intubation (RR = 0.78 [95% CI: 0.62, 0.99], p = .04). Oil-based GIT decontamination using paraffin oil showed benefits over conventional lavage regarding the incidence of in-hospital mortality and endotracheal intubation, and survival time. Coconut oil showed some benefits in terms of the intubation incidence and survival time. Decontamination using paraffin oil is recommended. Future clinical trials are warranted with larger sample sizes and focusing on cost-benefit and safety.

A review of the epidemiological and laboratory evidence of the role of aluminum exposure in pathogenesis of cardiovascular diseases. ENVIRONMENTAL RESEARCH 2024; 242:117740. [PMID: 38007081 DOI: 10.1016/j.envres.2023.117740] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/19/2023] [Revised: 11/13/2023] [Accepted: 11/18/2023] [Indexed: 11/27/2023]
Abstract
The objective of the present study was to review the epidemiological and laboratory evidence on the role of aluminum (Al) exposure in the pathogenesis of cardiovascular diseases. Epidemiological data demonstrated an increased incidence of cardiovascular diseases (CVD), including hypertension and atherosclerosis in occupationally exposed subjects and hemodialysis patients. In addition, Al body burden was found to be elevated in patients with coronary heart disease, hypertension, and dyslipidemia. Laboratory studies demonstrated that Al exposure induced significant ultrastructural damage in the heart, resulting in electrocardiogram alterations in association with cardiomyocyte necrosis and apoptosis, inflammation, oxidative stress, inflammation, and mitochondrial dysfunction. In agreement with the epidemiological findings, laboratory data demonstrated dyslipidemia upon Al exposure, resulting from impaired hepatic lipid catabolism, as well as promotion of low-density lipoprotein oxidation. Al was also shown to inhibit paraoxonase 1 activity and to induce endothelial dysfunction and adhesion molecule expression, further promoting atherogenesis. The role of Al in hypertension was shown to be mediated by up-regulation of NADPH-oxidase, inhibition of nitric oxide bioavailability, and stimulation of renin-angiotensin-aldosterone system. It has been also demonstrated that Al exposure targets cerebral vasculature, which may be considered a link between Al exposure and cerebrovascular diseases. Findings from other tissues lend support that ferroptosis, pyroptosis, endoplasmic reticulum stress, and modulation of gut microbiome and metabolome are involved in the development of CVD upon Al exposure. A better understanding of the role of the cardiovascular system as a target for Al toxicity will be useful for risk assessment and the development of treatment and prevention strategies.

Abstract
Background Severe refractory hypotension and cardiogenic shock are the main contributors to death in acute aluminum phosphide (ALP) poisoning. Shock index (SI) and modified shock index (MSI) are easily obtained parameters that reflect shock at an early stage. Aim This study aimed to evaluate the role of SI and MSI in the prediction of the severity and outcomes of acute ALP poisoned patients. Patients and methods This cross sectional study was conducted on patients admitted to Tanta University Poison Control Centre with acute ALP poisoning from April 2022 to March 2023. Socio-demographics and toxicological data were taken, findings of clinical examination and laboratory investigations were recoded, SI was calculated by dividing heart rate over systolic blood pressure, and MSI was obtained by dividing heart rate over mean arterial pressure. Poisoning severity was assessed using poisoning severity score (PSS). Patients were divided into groups according to intensive care unit (ICU) admission and mortality. Results The study enrolled 94 patients. The median values of SI and MSI were significantly higher in ICU-admitted patients and non-survivors rather than their comparable groups. Significant positive correlations were observed between each of SI and MSI and PSS. At cut-off >1.14, SI conveyed fair performance to predict ICU admission and mortality (AUC = 0.710 and 0.739, respectively). Similarly, MSI had fair performance to predict ICU admission (AUC = 0.731) and mortality (AUC = 0.744) at cut-off >1.47 and >1.5, respectively. Conclusion Both SI and MSI could be considered simple bedside adjuncts to predict ICU admission and mortality in acute ALP poisoning.

Abstract
Objective Mortality prediction in acute poisoning patients aids in prompt and effective treatment. This study aimed to evaluate the effectiveness of the new Poisoning Mortality Score (PMS) in comparison with the Poison Severity Score (PSS) and Sequential Organ Failure Assessment (SOFA) scoring systems in poisoned patients admitted to the intensive care unit (ICU). Material and Methods The medical records of 523 poisoned patients admitted to the ICU of the Poison Control Centre from September 2021 to June 2022 were examined retrospectively. The PMS, PSS, and SOFA scores were calculated based on the worst values of the first 24 h of admission. Results A total of 100 patients were enrolled in the study, and the in-hospital mortality rate was 28%. The best cut-off points for predicting mortality for PMS, PSS, and SOFA scores were > 53, > 2, and > 6, with sensitivities of 67.9%, 85.7%, and 82.4% and specificities of 73.6%, 84.7%, and 83.3% respectively. In a pairwise comparison of the AUCs for PMS, PSS, and SOFA scores, SOFA displayed significantly greater accuracy than PSS and PMS. Conclusion The PMS, PSS, and SOFA scoring systems were significant predictors of mortality in ICU-admitted poisoned patients, however, the SOFA score showed the best performance (OR = 1.77, and 95% CI = 1.42-2.54) with significant P-value (0.002) as a predictor of mortality and highest AUC(0.904).

Int J Immunopathol Pharmacol 2024; 38:3946320241250286. [PMID: 38764158 PMCID: PMC11104032 DOI: 10.1177/03946320241250286] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2023] [Accepted: 04/12/2024] [Indexed: 05/21/2024] Open
Abstract
Background: Aluminum phosphide (AlP) poisoning is prevalent in numerous countries, resulting in high mortality rates. Phosphine gas, the primary agent responsible for AlP poisoning, exerts detrimental effects on various organs, notably the heart, liver and kidneys. Numerous studies have documented the advantageous impact of Coenzyme Q10 (CoQ10) in mitigating hepatic injuries. The objective of this investigation is to explore the potential protective efficacy of CoQ10 against hepatic toxicity arising from AlP poisoning. Method: The study encompassed distinct groups receiving almond oil, normal saline, exclusive CoQ10 (at a dosage of 100 mg/kg), AlP at 12 mg/kg; LD50 (lethal dose for 50%), and four groups subjected to AlP along with CoQ10 administration (post-AlP gavage). CoQ10 was administered at 10, 50, and 100 mg/kg doses via Intraparietal (ip) injections. After 24 h, liver tissue specimens were scrutinized for mitochondrial complex activities, oxidative stress parameters, and apoptosis as well as biomarkers such as aspartate transaminase (AST) and alanine transaminase (ALT). Results: AlP induced a significant decrease in the activity of mitochondrial complexes I and IV, as well as a reduction in catalase activity, Ferric Reducing Antioxidant Power (FRAP), and Thiol levels. Additionally, AlP significantly elevated oxidative stress levels, indicated by elevated reactive oxygen species (ROS) production, and resulted in the increment of hepatic biomarkers such as AST and ALT. Administration of CoQ10 led to a substantial improvement in the aforementioned biochemical markers. Furthermore, phosphine exposure resulted in a significant reduction in viable hepatocytes and an increase in apoptosis. Co-treatment with CoQ10 exhibited a dose-dependent reversal of these observed alterations. Conclusion: CoQ10 preserved mitochondrial function, consequently mitigating oxidative damage. This preventive action impeded the progression of heart cells toward apoptosis.

Abstract
Background and objectives Aluminum phosphide (AlP), known as "rice tablet," is widely used as an effective pesticide. However, AlP poisoning is a common cause of mortality in many countries, such as Iran. Unfortunately, there is no specific antidote for AlP toxicity to date. AlP releases phosphine gas when it is exposed to moisture or acid. Phosphine is a potent mitochondrial toxin that could significantly inhibit cellular energy metabolism. AlP poisoning is an emergency condition that needs instant and effective intervention. Dihydroxyacetone (DHA) is a simple saccharide used for several pharmacological as well as cosmetic purposes. Previously, we found that DHA could significantly prevent mitochondrial impairment induced by toxic agents such as cyanide and phosphine in various in vitro and in vivo experimental models. Methods Hospitalized patients (n = 111) were evaluated for eligibility criteria. Among these patients, n = 35 cases were excluded due to incomplete data (n = 11) and suspicion of poisoning with poisons other than AlP (n = 24). Meanwhile, n = 76 cases with confirmed AlP poisoning were included in the study. AlP-poisoned patients who did not receive DHA (n = 18) were used as the control group.Patients (n = 58) received at least one dose of DHA (500 ml of 5 % DHA solution w/v, i.v.) as an adjuvant therapy in addition to the routine treatment of AlP poisoning. Arterial blood gas (ABG), blood pH, bicarbonate levels, and other vital signs and biochemical measurements were monitored. Moreover, the mortality rate and hospitalization time were evaluated in DHA-treated and AlP-poisoned patients without DHA administration. Several biomarkers were assessed before (upon hospitalization) and after DHA treatment. The routine tests for AlP-poisoned patients in this study were the measurement of electrolytes (K+ and Na+), WBC, RBC, hemoglobin, INR, carbonate (HCO3), blood pH, PaCO2, and PaO2 and SGPT, SGOT, BUN, Cr. Results Upon patients' admission, significant decreases in blood pH (acidosis), blood PaO2, and HCO3 levels were the hallmarks of AlP poisoning. It was found that DHA significantly alleviated biomarkers of AlP poisoning and tremendously enhanced patients' survival rate (65.52 % in DHA-treated vs 33.34 % in the control group) compared to patients treated based on hospital routine AlP poisoning protocols (no DHA). No significant adverse effects were evident in DHA-treated patients in the current study. Interpretation and conclusions These data suggest that parenteral DHA is a novel and effective antidote against AlP poisoning to be used as an adjuvant in addition to routine supportive treatment.

Abstract
This systematic review and meta-analysis pool evidence available from clinical trials to verify the effect of antioxidants on the outcome of acute aluminum phosphide (AlP) poisoning. A systematic review complied with "Preferred Reporting Items for Systematic Reviews and Meta-Analyses" (PRISMA) Protocols. Meta-analysis was conducted on 10 studies that fulfill eligibility criteria. Four antioxidants were implemented: N-Acetyl cysteine (NAC), L-Carnitine, Vitamin E, and Co-enzyme Q10 (Co Q10). Risk of bias, publication bias, and heterogeneity were assessed to ensure the results' reliability. Antioxidants significantly decrease mortality of acute AlP poisoning around three folds (OR = 2.684, 95% CI: 1.764-4.083; P < .001) and decrease the need for intubation and mechanical ventilation by two folds (OR = 2.391, 95% CI 1.480-3.863; P < .001) compared with control. Subgroup analysis revealed that NAC significantly decreases mortality by nearly three folds (OR = 2.752, 95% CI: 1.580-4.792; P < .001), and vitamin E significantly decreases mortality by nearly six folds (OR = 5.667, 95% CI: 1.178-27.254; P = .03) compared with control. L-Carnitine showed a borderline significance (P = .050). Co Q10 decreased the mortality compared with the control; however, the difference was not statistically significant (P = .263). This meta-analysis provides solid evidence regarding the efficacy of antioxidants in improving the outcome of acute AlP poisoning with reference to NAC. Wide confidence interval and small relative weight affect reliability regarding vitamin E efficacy. Future clinical trials and meta-analyses are recommended. To our knowledge, no previous meta-analysis was conducted to investigate the efficacy of treatment modalities for acute AlP poisoning.

Abstract
Aluminum phosphide (ALP)-induced cardiotoxicity is a major cause of high mortality rates. As there is no specific antidote, restoring cardiac hemodynamics is the cornerstone for saving patients. Based on oxidative stress theory in acute ALP poisoning, we examined the cardioprotective role of coconut oil and Coenzyme Q10 (COQ10) in ALP poisoning, focusing on their antioxidant capacity. This study was a randomized, controlled, single-blind, phase II clinical trial conducted at Tanta Poison Control Center over 1 year. Eighty-four ALP poisoned patients received supportive treatment and were randomly allocated to three equal groups. Gastric lavage was performed using sodium bicarbonate 8.4% with saline in group I. Alternatively, group II received 50 ml coconut oil, and group III initially received 600 mg CoQ10 dissolved in 50 ml coconut oil; and repeated 12 hours later. In addition to patient characteristics, clinical, laboratory, electrocardiography (ECG), and total antioxidant capacity (TAC) data were recorded and repeated 12 hours later. Patient outcomes were evaluated. There was no significant difference among groups considering patient characteristics, initial cardiotoxicity severity, vital, laboratory data, ECG changes, and TAC. However, 12 hours post-admissions, group III was significantly improved in all clinical, laboratory, and ECG parameters than comparable groups. Significant correlations were observed between elevated TAC in groups II and III with hemodynamic, serum troponin, and ECG variables. Accordingly, the need for intubation, mechanical ventilation, and the total vasopressor dose was significantly decreased in group III compared with other groups. Therefore, coconut oil and COQ10 are promising cardioprotective adjuvant therapy ameliorating the ALP-induced cardiotoxicity.

Abstract
The use of metal phosphides, particularly aluminum phosphide, poses a significant threat to human safety and results in high mortality rates. This study aimed to determine mortality patterns and predictive factors for acute zinc and aluminum phosphide poisoning cases that were admitted to Menoufia University Poison and Dependence Control Center from 2017 to 2021. Statistical analysis revealed that poisoning was more common among females (59.7%), aged between 10 and 20 years, and from rural regions. Most cases were students, and most poisonings were the result of suicidal intentions (78.6%). A new hybrid model named Bayesian Optimization-Relevance Vector Machine (BO-RVM) was proposed to forecast fatal poisoning. The model achieved an overall accuracy of 97%, with high positive predictive value (PPV) and negative predictive value (NPV) values of 100% and 96%, respectively. The sensitivity was 89.3%, while the specificity was 100%. The F1 score was 94.3%, indicating a good balance between precision and recall. These results suggest that the model performs well in identifying both positive and negative cases. Additionally, the BO-RVM model has a fast and accurate processing time of 379.9595 s, making it a promising tool for various applications. The study underscores the need for public health policies to restrict the availability and use of phosphides in Egypt and adopt effective treatment methods for phosphide-poisoned patients. Clinical suspicion, positive silver nitrate test for phosphine, and analysis of cholinesterase levels are useful in diagnosing metal phosphide poisoning, which can cause various symptoms.

Abstract
Aluminum phosphide (AlP) is widely used for protecting grains from pests. AlP releases toxic phosphine gas (PH3) while exposed to humidity. Poisoning with these tablets is dangerous and can cause death or serious injuries. Up to now, no definite antidote has been introduced for specific treatment of this poisoning. Sevelamer carbonate or sevelamer hydrochloride (Renagel) is a polymeric pharmaceutical prescribed for treating hyperphosphatemia in patients with chronic kidney disease. Sevelamer can bind with phosphate groups and act as an anion exchanger. Herein, sevelamer is repurposed as a potent antidote agent in phosphine gas poisoning. In vivo evaluation was conducted on male Sprague Dawley rats. The evaluation was conducted on three groups of animals: control, AlP-poisoned, and AlP-poisoned treated with sevelamer. Survival percentage, serum biomarkers level of organ injury, and ATP level were recorded. The results indicate a high survival rate in sevelamer-treated animals compared with the AlP-poisoned group (75% vs. 0% respectively, 48 h after poisoning). The analysis of serum markers of organ injury also showed that sevelamer could reduce toxicity and organ injury in poisoned animals. ATP level of separate organs showed that sevelamer treated groups were recovered. The results showed that sevelamer could be a potent antidote for managing aluminum phosphide poisoning. Moreover, a mechanism is suggested for the interaction of sevelamer with phosphine gas.

Abstract
BACKGROUND Aluminum phosphide (ALP) intoxication either accidentally or intentionally, is one of the major health concerns in developing countries. Its poisoning causes severe damage to organs including the heart and liver. OBJECTIVES This study aimed to investigate the hepato- and cardioprotective effects of quercetin (QCN) on the acute/subacute toxicity of ALP in rodent models. METHODS Acute (single dose, 12.5 mg/kg, orally) and subacute (2 mg/kg, orally and 7 days) intoxication of ALP were induced in rats and the protective effects of QCN on altered hepatic/cardiac functional enzyme concentrations, myeloperoxidase activity, oxidative stress biomarkers, and histopathological changes were studied at three doses of 10, 50 and 100 mg/kg BW. To record any heart abnormality, an electrocardiogram (ECG) was recorded 3 h after the last treatment. RESULTS Quercetin reduced the ALP-increased hepatic and cardiac functional enzyme concentrations and myeloperoxidase activity. Moreover, QCN improved remarkably the ALP-induced ECG abnormalities (T inversion, bigeminy in R waves) and arrhythmias. QCN attenuated significantly (p < 0.05) the ALP-induced oxidative/ nitrosative stress and histopathological injuries in the liver and heart. CONCLUSION Our results suggest that QCN is able to protect the ALP-induced cardiac and hepatic injuries in both acute and subacute models and its effects attribute to its antioxidant and anti-inflammatory properties.

Abstract
Previous studies have demonstrated that phosphine gas (PH3) released from aluminium phosphide (AlP) can inhibit cytochrome oxidase in cardiac mitochondria and induce generation of free radicals, oxidative stress, alteration in antioxidant defense system and cardiotoxicity. Available evidence suggests that cannabinoids have protective effects in the reduction of oxidative stress, mitochondrial and cardiovascular damages. The objective of this study was to evaluate the effect of trans-Δ-9-tetrahydrocannabinol (THC) on AlP-induced toxicity in isolated cardiomyocytes and cardiac mitochondria. Rat heart isolated cardiomyocytes and mitochondria were cotreated with different concentrations of THC (10, 50 and 100 μM) and IC50 of AlP, then cellular and mitochondrial toxicity parameters were assayed. Treatment with AlP alone increased the cytotoxicity, depletion of cellular glutathione (GSH), mitochondrial reactive oxygen species (ROS) generation, lipid oxidation, mitochondria membrane potential (ΔΨm) collapse and mitochondrial swelling, when compared to control group. However, incubation with THC (10, 50 and 100 μM) attenuated the AlP-induced changes in all these parameters in a THC concentration-dependent manner. Interestingly, the obtained results showed remarkably significant protective effects of THC by attenuation the different parameters of cytotoxicity, mitochondrial toxicity and oxidative stress induced by ALP in isolated cardiomyocytes and cardiac mitochondria. It is the first report showing the protective effects of THC against AlP-induced toxicity, and these effects are related to antioxidant potential and inhibition of mitochondria permeability transition (MPT) pore. Based on these results, it was hypothesized that THC may be used as a potential therapeutic agent for the treatment of AlP-induced mitochondrial dysfunction and cardiotoxicity.

Abstract
INTRODUCTION Cardiotoxicity represents the primary cause of death in acute aluminum phosphide (AlP) poisoning. Prompt supportive care can improve patient survival. This study assessed the role of echocardiography in estimating the survival probability of AlP-poisoned patients admitted to the intensive care unit. METHODS A prospective cohort study of symptomatic acute AlP poisoned patients was conducted between September 2019 and December 2020. Patients were subjected to history taking, clinical examination, To be included, patient evaluation needed to include electrocardiographic (ECG) and echocardiographic studies. The statistical analysis assessed the association between patient survival and relevant factors. Survival analysis was performed using the Kaplan-Meier survival curve and Cox proportional hazard regression. RESULTS A total of 90 patients met inclusion criteria. Electrocardiographic abnormalities were detected in 38.1% of survivors and 82.6% of non-survivors (p < 0.001). Survivors had a higher mean left ventricle ejection fraction (LVEF) (50.86 ± 6.30% vs. 26.52 ± 7.64%, respectively, p < 0.001) and a lower percentage of global LV hypokinesia (4.8% vs. 94.2%, p < 0.001). The mean survival time was higher among patients with LVEF ≥ 50% than those with LVEF = 41-49% and ≤ 40% (p = 0.014 and 0.001, respectively). The hazard of death was 4.42 and 5.40 times greater in patients with LVEF ≤ 40% or with global LV hypokinesia, respectively. Regression revealed that the global LV hypokinesia, ECG abnormalities, and decreased LVEF and oxygen saturation were significantly associated with the risk of death (hazard ratios: 4.382, 3.348, 0.957, and 0.971, respectively). CONCLUSIONS Echocardiography represents a valuable diagnostic tool to assess cardiac function in acute AlP poisoning. Both LVEF and global LV hypokinesia significantly impact the survival of AlP-poisoned patients. Echocardiography was superior to ECG changes in terms of accuracy for the prediction of mortality.

Abstract
Due to its easy availability, rapid and severe toxicity, and no specific antidote, aluminum phosphide has emerged as a lethal toxin, commonly used for suicidal intent in agricultural communities. Despite various advances in medicine, this compound's toxicity is poorly understood, and it still has a very high case fatality rate with no definitive treatment options available. This review aims to understand the mechanism of toxicity, clinical toxidrome of acute aluminum phosphide poisoning, and the available therapeutic options, including recent advances. A literature review was performed searching PubMed, EMBASE Ovid, and Cochrane Library, using the following search items: ("aluminum phosphide poisoning" OR "aluminum phosphide poisoning toxicity" OR "aluminum phosphide ingestion") AND ("management" OR "therapy" OR "treatment"). Selected articles were discussed amongst all the authors to shape this review. High case fatality rate and lack of any specific antidote are persisting challenges. Therapeutic measures need to be implemented from all fronts - reducing easy access to the poison, developing less toxic alternatives for use as a pesticide, and more studies directed at developing an effective reversal agent for phosphine. The advent of promising agents like glucose-insulin-potassium infusion and lipid emulsion is a new ray of hope in the complete recovery in this fatal poisoning. The need of the hour is to find an agent that rapidly and effectively reverses aluminum phosphide's toxic effects. Large multicenter controlled trials are required to establish the role of glucose-insulin-potassium and lipid emulsion.

Abstract
Humans are unconsciously exposed to environmental toxins including heavy metals as well as various pesticides, which have deleterious effects on human health. Accumulating studies pointed out that exposure to environmental toxins was associated with various cardiopathologic effects. This review summarizes the main mechanisms of cardiotoxicity induced by environmental toxins (cadmium, arsenic and pesticides) and discusses the potential preventive effects of natural products. These findings will provide a theoretical basis and novel agents for the prevention and treatment of environmental toxins-induced cardiotoxicity. Furthermore, the limitations of current studies, future needs and priorities are discussed.

Abstract
Early risk stratification of acutely poisoned patients is essential to identify patients at high risk of intensive care unit (ICU) admission. We aimed to develop a prognostic model and risk-stratification nomogram based on the readily accessible clinical and laboratory predictors on admission for the probability of ICU admission in acutely poisoned patients. This retrospective cohort study included adult patients with acute toxic exposure to a drug or a chemical substance. Patients' demographic, toxicologic, clinical and laboratory data were collected. Among the 1260 eligible patients, 180 (14.3%) were admitted to the ICU. We developed a generalized prognostic model for predicting ICU admission in patients with acute poisoning. The predictors included the Glasgow coma scale, oxygen saturation, diastolic blood pressure, respiratory rate and blood bicarbonate concentration. The model displayed excellent discrimination and calibration (optimistic-adjusted area under the curve = 0.924 and optimistic-adjusted Hosmer and Lemeshow test = 0.922, respectively) when internally validated. Additionally, we developed prognostic models that determine ICU admission in patients with specific poisonings. Furthermore, we constructed risk-stratification nomograms that rank the probability of ICU admission in these patients. The developed risk-stratification nomograms help decision-making regarding ICU admission in acute poisonings. Future external validation in independent cohorts is necessary before clinical application.

Abstract
These days, poisoning with aluminium phosphide (AlP), is one of the main health threats in human societies. Previous studies have been reported that cardiotoxicity induced by AlP, via mitochondrial dysfunction and oxidative stress is the main cause of death in victims. On the other, collectively, multiple lines of evidence strongly suggest that calcitriol has mitochondrial protective and antioxidant effects. Therefore, we assumed that calcitriol could presumably ameliorate AlP-induced oxidative stress and mitochondrial dysfunction in cardiomyocytes. Mitochondria and cardiomyocytes were isolated by differential centrifugation and collagenase perfusion respectively from rat heart. The isolated cardiomyocytes and mitochondria were cotreated with different concentrations of calcitriol (0.2, 0.4 and 1 μg/ml) and AlP (20 μg/ml) for 3 h. The parameters of cellular toxicity including; cytotoxicity, reactive oxygen species (ROS) formation, malondialdehyde (MDA) level, mitochondria membrane potential (ΔΨm) collapse, lysosomal membrane integrity, the level of oxidized and reduced glutathione (GSH and GSSG), and mitochondrial toxicity parameters including; succinate dehydrogenase (SDH) activity and mitochondrial swelling were analyzed using biochemical and flow cytometric evaluations. Administration of AlP significantly increased cytotoxicity, GSH depletion, cellular ROS formation, MDA level, mitochondrial and lysosomal dysfunction in isolated cardiomyocytes. In isolated mitochondria, AlP decreased SDH activity and mitochondrial swelling. The cotreatment of isolated cardiomyocytes and mitochondria with calcitriol (0.4 and 1 μg/ml) and AlP (20 μg/ml) showed the ability to reduce the toxic effects of AlP. These findings suggest a potential therapeutic role of calcitriol in protecting cardiomyocytes and cardiac mitochondria from oxidative damage induced by AlP. According to the results, calcitriol exerted ameliorative effects against AlP-induced cytotoxicity and mitochondrial toxicity, and the effect was attributed to the antioxidant properties.

Abstract
Metal phosphides, especially aluminum phosphide, and phosphine (PH3 ) are widely used as insecticides and rodenticides for protection of grains during process of storage and transportation. The main reason of poisoning with this compound is related to the conscious ingestion of salts or accidental inhalation of PH3 . So the early and accurate diagnosis of poisoning can significantly help to the effective clinical treatment or recognition of death cause. PH3 is somewhat unstable due to reaction with oxygen or hemoglobin leading to formation of oxy-acids phosphorous. Here, we critically reviewed the literature introducing the quantitative and qualitative methods for the detection of metal phosphides, PH3 , and its products. This study obviously demonstrates that during past years, different diagnosis methods have been remarkably progressed. Head-space gas chromatography and confirmatory colorimetric methods have been as the most popular techniques. Also, the gas sensors are a promising method that must be more progressed.

Abstract
Acute cardiovascular poisoning is a major cause of adverse outcomes in poisoning emergencies. The prognostic validity of corrected QT (QTc) and dispersed QT (QTd) in these outcomes is still limited. The present study aimed to determine the risk factors of mortality, adverse cardiovascular events (ACVE), and intensive care unit (ICU) admission in patients with acute cardiovascular toxicities and assess the validity of QTc and QTd intervals in predicting these outcomes. This study was conducted on adult patients admitted to Tanta University Poison Control Center with a history of acute cardiotoxic drugs or toxins exposure. The demographic and toxicological data of patients were recorded. Clinical examination, routine laboratory investigations, ECG grading, and measurement of QTc and QTd were performed. The patients were grouped according to their adverse outcomes. Among the included patients, 51 (31.48%) patients died, 61 (37.65%) patients had ACVE, and 68 (41.98%) patients required ICU admission. The most common cause of poisoning is aluminum phosphide, followed by cholinesterase inhibitors. QTd and QTdc showed no significant difference among outcome groups. The best cut-off values of QTc to predict mortality, ACVE, and ICU admission were > 491.1 ms, > 497.9 ms, and ≥ 491.9 ms, respectively. The derived cut-off QTc values were independent predictors for all adverse outcomes after adjusting for poison type, serum HCO3, and pulse. The highest odds ratios for all adverse outcomes were observed in aluminum phosphide poisoning and low HCO3 < 18 mmol/L. Thus, serum HCO3 and QTc interval should be monitored for acute cardiotoxicities, especially in aluminum phosphide and cholinesterase inhibitors poisoning.
