Abstract
Organophosphate poisoning (OPP) remains a significant public health issue globally, particularly in middle- and low-income countries. This study aimed to assess the effectiveness of physiotherapy interventions in managing patients with OPP, focusing on reducing the severity of intermediate syndrome symptoms and associated complications such as respiratory muscle weakness and bilateral loculated pleural effusions. A 48-year-old male with a history of alcohol consumption was transferred to the medicine intensive care unit due to poison ingestion. The patient exhibited symptoms of respiratory distress and decreased consciousness, necessitating intubation and mechanical ventilation. Physiotherapy interventions included patient education, secretion mobilization, vital capacity improvement, secondary complication prevention, chest expansion exercises, dyspnea-relieving positions, and mobilization. The patient's progress was monitored using various scales, including the Functional Independence Measure Scale, ICU Mobility Scale, and Chelsea Critical Care Physical Assessment Tool. Significant improvements in functional independence, mobility, and psychological well-being were observed throughout the intervention period. This study highlights the importance of physiotherapy in the comprehensive management of OPP, emphasizing its role in mitigating respiratory complications and improving overall functional outcomes.

NANOMATERIALS (BASEL, SWITZERLAND) 2024; 14:1046. [PMID: 38921922 PMCID: PMC11206780 DOI: 10.3390/nano14121046] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/25/2024] [Revised: 06/12/2024] [Accepted: 06/13/2024] [Indexed: 06/27/2024]
Abstract
Extensive use of pesticides in agricultural production has been causing serious health threats to humans and animals. Among them, phorate is a highly toxic organophosphorus insecticide that has been widely used in planting. Due to its harmful effects on human and animal health, it has been restricted for use in many countries. Analytical methods for the rapid and sensitive detection of phorate residues in agricultural products are urgently needed. In this study, a new method was developed by combining surface-enhanced Raman spectroscopy (SERS) and immunochromatography assay (ICA). Hybrid magnetic Fe3O4@Au@DTNB-Ab nanoprobes were prepared by modifying and growing Au nanoseeds on an Fe3O4 core. SERS activity of the nanoprobe was optimized by adjusting the concentration of the Au precursor. A rapid and sensitive assay was established by replacing the traditional colloidal gold-based ICA with hybrid SERS nanoprobes for SERS-ICA. After optimizing parameters including coating antibody concentrations and the composition and pH of the buffer solution, the limit of detection (LOD) for phorate could reach 1 ng/mL, with a linear range of 5~100 ng/mL. This LOD is remarkably lower than the maximum residue limit in vegetables and fruits set by the Chinese government. The feasibility of this method was further examined by conducting a spiking test with celery as the real sample. The result demonstrated that this method could serve as a promising platform for rapid and sensitive detection of phorate in agricultural products.

Abstract
Organophosphate poisoning is a significant global health concern with implications for both occupational and environmental settings. This comprehensive review thoroughly explores the biochemical basis, clinical presentation, diagnostic methods, treatment strategies, and long-term effects of organophosphate exposure. The acute phase is characterized by cholinergic crisis, respiratory distress, and neurological manifestations, while delayed complications include the intermediate syndrome and organophosphate-induced delayed neuropathy. Diagnostic approaches involve clinical evaluation, cholinesterase-level assessments, and imaging studies. Treatment strategies encompass decontamination, antidotes such as atropine and pralidoxime, and supportive care. Long-term effects may include cognitive and neurological sequelae, necessitating rehabilitation approaches such as physical and occupational therapy. Prevention strategies include stringent occupational safety guidelines, sustainable agricultural practices, and public awareness initiatives. The implications for clinical practice underscore the importance of a multidisciplinary approach. At the same time, the call to action emphasizes the need for collaborative efforts in prevention and awareness to mitigate the impact of organophosphate poisoning on public health and the environment.

Abstract
Organophosphate poisoning (OPP) results from the occupational, accidental, or suicidal intake of organophosphate pesticides (OPs). There is a huge limitation in the available literature on OPP cases and the role of physiotherapy in such cases. We report a case of a 33-year-old farmer, found in a state of ingested insecticide and admitted to the emergency department. The patient had two to three episodes of vomiting, associated with continuous tremors in his hands and legs. Immediately infused with atropine, the patient's general condition deteriorated, and he was intubated with an endotracheal tube. With the signs of long-term intubation, a tracheostomy was done. A respiratory therapy consult was taken for indications of intermediate syndrome and to achieve early weaning. The patient's referral was received in view of the long-term requirement of bronchial hygiene and the need for early ambulation as well as psychological support. Informed consent was taken from the family prior to the commencement of the treatment. Respiratory therapy interventions included body positioning, bronchial hygiene techniques, chest proprioceptive neuromuscular facilitation (PNF) techniques, and mobility exercises to achieve early ambulation. Physiotherapists have the appropriate training, knowledge, and skills to deliver the exercise components and help patients return to their activities of daily living. Significant levels of improvement have been seen in the general condition of the patient. The overall functioning of the patient's health was seen as improved on the scales of consciousness, early mobility in the step-down unit, and quality of life.

Abstract
Acute poisoning is a significant public health concern. This retrospective study investigates trends in acute poisoning cases and explores the clinical and sociodemographic profiles associated with this condition. Medical data from 859 hospitalized patients diagnosed with acute poisoning between January 2017 and December 2022 were comprehensively analyzed. The descriptive statistical analysis revealed that 360 patients had underlying diseases, with depression being the most prevalent among them. Furthermore, urban areas accounted for 87.2% of the acute poisoning cases, indicating a higher incidence compared to rural areas. The substances implicated in acute poisoning incidents varied, with drugs of abuse being the most common (53.2%), followed by pesticides (22.2%), carbon monoxide (11.8%), and alcohol (5.4%). Suicide attempt/suicide emerged as the leading cause of acute poisoning incidents, accounting for 75.9% of cases, while poisoning accidents predominantly occurred within the home setting. Through chi-square tests, it was determined that risk factors for suicide attempt/suicide included female gender and underlying medical conditions. Temporal analysis showed that the total number of acute poisoning cases increased from 2017 to 2019 and decreased from 2019 to 2022. Notably, suicide-related cases exhibited an upward trend, with suicide attempt/suicide accounting for over 80% of all acute poisoning cases after 2020. This study contributes valuable insights into the trends, profiles, and risk factors associated with acute poisoning cases.

Abstract
Organophosphorus Pesticides (OPPs) are among the extensively used pesticides throughout the world to boost agricultural production. However, persistent residues of these toxic pesticides in various vegetables, fruits, and drinking water poses detrimental health effects. Consequently, the rapid monitoring of these harmful chemicals through simple and cost-effective methods has become crucial. In such an instance, electrochemical methods offer simple, rapid, sensitive, reproducible, and affordable detection pathways. To overcome the limitations associated with electrochemical enzymatic sensors, non-enzymatic sensors have emerged as promising and simpler alternatives. The non-enzymatic sensors have demonstrated superior activity, reaching detection limit up to femto (10-15) molar concentration in recent years, leveraging higher selectivity obtained through the molecularly imprinted polymers, synergistic effects between carbonaceous nanomaterials and metals, metal oxide alloys, and other alternative approaches. Herein, this review paper provides an overview of the recent advancements in the development of non-enzymatic electrochemical sensors for the detection of commonly used OPPs, such as Chlorpyrifos (CHL), Diazinon (DZN), Malathion (MTN), Methyl parathion (MP) and Fenthion (FEN). The design method of the electrodes, electrode functioning mechanism, and their analytical performance metrics, such as limit of detection, sensitivity, selectivity, and linearity range, were reviewed and compared. Furthermore, the existing challenges within this rapidly growing field were discussed along with their potential solutions which will facilitate the fabrication of advanced and sustainable non-enzymatic sensors in the future.

Abstract
Industrial production of food for animals and humans needs increasing amounts of pesticides, especially of organophosphates, which are now easily available worldwide. More than 3 million cases of acute severe poisoning are estimated to occur worldwide every year, and even more cases remain unreported, while 200,000–350,000 incidentally or intentionally poisoned people die every year. Diagnostic and therapeutic procedures in organophosphate poisoning have, however, remained unchanged. In addition to several neurologic symptoms (miosis, fasciculations), hypersecretion of salivary, bronchial, and sweat glands, vomiting, diarrhea, and loss of urine rapidly induce dehydration, hypovolemia, loss of conscience and respiratory distress. Within hours, signs of acidosis due to systemic hypoxia can be observed at first laboratory investigation after hospitalization. While determination of serum-cholinesterase does not have any diagnostic value, it has been established that hypoalbuminemia alone or accompanied by an increase in creatinine, lactate, or C-reactive protein serum levels has negative prognostic value. Increased serum levels of C-reactive protein are a sign of systemic ischemia. Protective mechanical ventilation should be avoided, if possible. In fact, acute respiratory distress syndrome characterized by congestion and increased weight of the lung, accompanied by heart failure, may become the cause of death. As the excess of acetylcholine at the neuronal level can persist for weeks until enough newly, locally synthesized acetylcholinesterase becomes available (the value of oximes in reducing this time is still under debate), after atropine administration, intravenous albumin and fluid infusion should be the first therapeutic interventions to reestablish normal blood volume and normal tissue oxygenation, avoiding death by cardiac arrest.
