Introduction: Common major co-formulants in glyphosate-based herbicides, polyethoxylated tallow amine surfactants, are suspected of being more toxic than glyphosate, contributing to the toxicity in humans. However, limited information exists on using polyethoxylated tallow amine concentrations to predict clinical outcomes. We investigated if plasma concentrations of glyphosate, its metabolite and polyethoxylated tallow amines can predict acute kidney injury and case fatality in glyphosate poisoning.

Introduction: Intestinal toxicity can occur following ingestion of various drugs, chemicals, and toxins. Intestinal fatty acid binding protein is a cytosolic protein specific to intestinal epithelial cells released into the systemic circulation following intestinal injury. Understanding intestinal toxicity in poisoning has the potential to explain mechanisms of toxicity and gastrointestinal symptoms.

Background: The treatment of glioblastomas, the most common primary malignant brain tumors, with a devastating survival perspective, remains a major challenge in medicine. Among the recently explored therapeutic approaches, 5-aminolevulinic acid (5-ALA)-mediated interstitial photodynamic therapy (iPDT) has shown promising results.

Methods: A total of 16 patients suffering from de novo glioblastomas and undergoing iPDT as their primary treatment were retrospectively analyzed regarding survival and the characteristic tissue regions discernible in the MRI data before treatment and during follow-up.

Background: FAO specifications for liquid paraquat dichloride SL formulations require the use of an emetic agent to stimulate vomiting within 30 min of ingestion. To date, there is no high-quality evidence of efficacy, despite use of the PP796 emetic since 1979. We first examined the validity of patients' self-reported dose of paraquat ingested by examining the relationship with blood paraquat concentration and time to death for patients ingesting the standard paraquat SL formulation in a Sri Lankan cohort.

Aim: Alcohol is a commonly co-ingested compound during self-poisoning with pesticides. Clinical experiences suggest alcohol co-ingestion (or withdrawal) makes patient management more difficult after self-poisoning and may contribute to poor clinical outcomes. We aimed to systematically review the world literature to explore the relationship between alcohol co-ingestion and outcome in pesticide self-poisoning.

Background: Pesticide self-poisoning is a global clinical and public health problem. While self-poisoning with insecticides and herbicides has been extensively studied, there is minimal literature on acute fungicide self-poisoning. We aimed to study the clinical course and outcome of fungicide self-poisoned patients recruited to a prospective cohort in Sri Lanka.

Background: Chronic Kidney Disease of unknown origin (CKDu) excludes known primary renal conditions or systemic disease (such as diabetes mellitus or hypertension). Prominence of CKDu has been noted for some decades in Sri Lanka, especially among men in particular rural areas, prompting many studies directed towards environmental causation. This article critically reviews relevant primary studies.

Objective: Abdominal pain is known to be an early clinical predictor of severe systemic Russell's viper (RV) envenomation and is often associated with the later development of coagulopathy and neurotoxicity. The mechanism of abdominal pain is unknown, but we postulated it might be due to intestinal microvascular endothelial gut damage. Gut-toxicity can be detected using the novel biomarker Intestinal Fatty Acid Binding Protein (IFABP).

Article Synopsis
  • Phenthoate is a widely used organophosphorus pesticide that can cause serious health issues when ingested, with limited research available on its effects, prompting a study in Sri Lanka.
  • In a study involving 292 patients who self-poisoned with phenthoate, 14.4% required intubation, with a notable case fatality rate of 6.5%, and deaths primarily occurred within the first 24 hours post-ingestion.
  • The study noted a brief increase in cholinesterase enzyme activity in some patients treated with pralidoxime chloride, but this increase was not maintained over time, indicating challenges in effectively treating phenthoate poisoning.

Article Synopsis
  • * A systematic review of existing research identified 21 studies related to urinary and circulating microRNAs in toxic acute kidney injury, with a notable emphasis on cisplatin and antibiotics as the leading nephrotoxins.
  • * Despite findings indicating that urinary miR-218 could predict acute kidney injury, the variability in research methods and lack of comprehensive human data highlight the need for further studies to explore a broader range of nephrotoxic agents, particularly common causes like pesticides and chemicals.

In this report, a new carbon allotrope named nanoleite is proposed. Its crystal structure is constructed by embedding carbon nanotubes into the matrix of lonsdaleite periodically, leading to a hexagonal primitive unit cell. The equilibrium structure of nanoleite is fully relaxed by density functional theory calculation, and we demonstrate that nanoleite is a semiconductor with an indirect energy bandgap of 2.

Previous studies on human acute kidney injury (AKI) following poisoning with potassium permanganate/oxalic acid (KMnO/HCO), paraquat, and glyphosate surfactant herbicide (GPSH) have shown rapid and large increases in serum creatinine (sCr) that cannot be entirely explained by direct nephrotoxicity. One plausible mechanism for a rapid increase in sCr is oxidative stress. Thus, we aimed to explore biomarkers of oxidative stress, cellular injury, and their relationship with sCr, after acute KMnO/HCO, paraquat, and GPSH poisonings.
