The value of toxicological analysis in acute poisoning patients with uncertain exposure histories:a retrospective and descriptive study from an institute of poisoning

BACKGROUND:In clinical practice,some patients might not be able or unwilling to provide a thorough history of medication and poison exposure.The aim of this study was to use toxicological analysis to examine the clinical characteristics of patients with acute poisoning whose exposure history was uncertain from a toxicological analysis perspective.METHODS:This was a retrospective and descriptive study from an institute of poisoning.Patient registration information and test reports spanning the period from April 1,2020 to March 31,2022,were obtained.Patients with uncertain exposure histories and who underwent toxicological analysis were included.Clinical manifestations and categories of toxics were analyzed.RESULTS:Among the 195 patients with positive toxicological analysis results,the main causes of uncertain exposure history was disturbance of consciousness(62.6%),unawareness(23.6%)and unwillingness or lack of cooperation(13.8%).The predominant clinical manifestations were disturbed consciousness(62.6%),followed by vomiting and nausea(14.4%)and liver function abnormalities(8.7%).A comparison of clinical manifestations between patients with positive and negative(n=99)toxicological analyses results revealed significantly different proportions of disturbances in consciousness(63%vs.21%),dizziness(1.5%vs.5.1%),multi-organ failure(1.5%vs.7.1%),and local pain(0 vs 4%).The main categories of substances involved were psychiatric medications(23.1%),sedatives(20.5%),insecticides(13.8%),and herbicides(12.8%).CONCLUSION:The clinical manifestations of acute poisoning in patients with an uncertain exposure history are diverse and nonspecific,and toxicological analysis plays a pivotal role in the diagnosis and differential diagnosis of such patients.

Clinical Case Report of Acute Heart Injury and Acute Rhabdomyolysis Due to Cyanide Poisoning

Cyanide poisoning is one of the most dangerous poisonings, and it can be absorbed into the body through the mouth, inhalation and through the skin. A 32-year-old female patient was admitted to our poison control center because of high fever, severe vomiting, and seizures. Physical examination found that the patient was drowsy, had a high fever of 40 degrees Celsius, pulse of 140 beats/minute, and increased tendon and bone reflexes. Exploiting the patient’s information, it was discovered that the patient bought Cyanide to drink with the intention of committing suicide. The patient was quickly treated with gastric lavage and activated charcoal. Echocardiography recorded EF: 35%, reduced movement of the entire myocardium. CK blood test: 4562 U/L. The patient’s condition rapidly deteriorated and the patient was made ECMO, IHD and CVVHDF. After 3 days of treatment, the patient’s condition did not improve, so the family asked for the patient to go home. This article aims to describe the rapidly progressing and severe damage to the heart and muscles of patients with cyanide poisoning.

Clinical correlates of hypotension in patients with acute organophosphorus poisoning

BACKGROUND:The aim of the present study is to describe the clinical correlates of hypotension and its associated outcomes in patients with acute organophosphorus poisoning(AOPP).METHODS:In this retrospective cohort study,we analyzed data pertaining to 871 patients with AOPP who were treated at two hospitals.Data from hypotensive and non-hypotensive patients were compared to identify clinical correlates of hypotension.We also evaluated the association between clinical parameters(including hypotension)and in-hospital mortality.RESULTS:The incidence of hypotension in AOPP patients was 16.4%.Hypotensive patients showed signifi cantly higher in-hospital mortality(1.1%vs.39.9%,P<0.001).Advanced age(odds ratio[OR]1.25,95%confi dence interval[CI]1.08–1.44),history of diabetes(OR 2.65,95%CI 1.14–5.96),and increased white blood cell count(OR 1.06,95%CI 1.03–1.09),plasma cholinesterase(OR 0.91,95%CI 0.84–0.94),plasma albumin(OR 0.88,95%CI 0.85–0.92),serum amylase(OR 1.01,95%CI 1.01–1.02),and blood pH(OR 0.64,95%CI 0.54–0.75)were signifi cantly associated with hypotension.After adjusting for potential confounders,hypotension was associated with increased in-hospital mortality(hazard ratio 8.77–37.06,depending on the controlled variables).CONCLUSIONS:Hypotension is a common complication of AOPP and is associated with increased in-hospital mortality.Advanced age,history of diabetes,and changes in laboratory parameters were associated with hypotension in AOPP patients.

Risk factors and optimal predictive scoring system of mortality for children with acute paraquat poisoning

BACKGROUND There is no suitable scoring system that can be used to predict mortality in children with acute paraquat intoxication(APP).AIM To optimize a predictive scoring system for mortality in children with APP.METHODS A total of 113 children with APP from January 1,2010 to January 1,2020 were enrolled in this study.These patients were divided into survivors and nonsurvivors.We compared the clinical characteristics between the two groups and analyzed the independent prognostic risk factors.The survival rates of patients with different values of the pediatric critical illness score(PCIS)were assessed using kaplan-meier survival analysis.The best scoring system was established by using the area under the receiver operating characteristic curve analysis.RESULTS The overall mortality rate was 23.4%.All non-survivors died within 20 days;48.1%(13/27)died within 3 days,and 70.3%(19/27)died within 7 days.Compared to survivors,the non-survivors were older,had higher white blood cell count,alanine aminotransferase(ALT),aspartate aminotransferase,serum creatinine,blood urea nitrogen,glucose,and pediatric early warning score,and had lower platelet count,albumin,Serum sodium(Na+)and PCIS.ALT and PCIS were the independent prognostic risk factors for children with APP.The survival rate of children classified as extremely critical patients(100%)was lower than that of children classified as critical(60%)or noncritical(6.7%)patients.The specificity of ALT was high(96.51%),but the sensitivity was low(59.26%).The sensitivity and specificity of ALT combined with PCIS were high,92.59%and 87.21%,respectively.The difference in mortality was significantly higher for ALT combined with PCIS(area under the receiver operating characteristic:0.937;95%CI:0.875-0.974;P<0.05).CONCLUSION In our study,ALT and PCIS were independent prognostic risk factors for children with APP.ALT combined with PCIS is an optimal predictive mortality scoring system for children with APP.

Objective:To investigate the effects of Changtuogning and Xuebijing combined with hemoperfusion on serum inflammatory factors and myocardial enzymes in patients with acute severe organophosphorus pesticide poisoning (AOPP).Methods: A total of 92 patients with acute severe AOPP who were admitted to our hospital from July 2015 to June 2018 were enrolled. All patients were divided into the observation group and the control group by randomized block method (n=46). The control group was treated with Changtuoning and Xuebijing, and the observation group was treated with Changtuoning and Xuebijing combined with blood perfusion. The clinical indexes, serum inflammatory factors, myocardial enzyme indexes, complications and adverse reactions were compared between the two groups.Results:The doses of atropine, recovery waking time, ChE recovery time and hospital stay in the observation group were significantly lower than those in the control group. The cure rate in the observation group was significantly higher than that in the control group (P<0.05). There was no significant difference between the two groups (P>0.05). The levels of TNF-α, IL-8 and IL-18 in the observation group were significantly lower than those in the control group (P<0.05). The levels of CK, CK-MB, LDH and AST in the observation group were significantly lower than those in the control group (P<0.05). The incidence of complications (intermediate syndrome, respiratory failure, pulmonary infection, pulmonary edema) in the observation group was significantly lower than that in the control group (P<0.05). The incidence of adverse reactions (myalgia, fatigue, digestive tract reaction, abnormal liver function) in the observation group was significantly lower than that in the control group (P<0.05).Conclusion:Changtuoning and Xuebijing combined with hemoperfusion have significant effects on patients with acute severe organophosphorus poisoning, which can effectively reduce inflammatory factors and improve myocardial enzyme index.

Nurse’s knowledge, attitude and practice on the initial management of acute poisoning among adult casualties: Study at Kenyatta National Hospital, Kenya

The purpose of this study was to determine nurse’s knowledge, attitude and practice on the initial management of acute poisoning among adult casualties seen at Accident and Emergency Department (AED), Kenyatta National Hospital (KNH). The study was cross sectional. Both qualitative and quantitative methods of data collection were employed. The target population were all nurses working at AED, KNH. Purposive sampling was used to select study subjects. Sample size included all Accident and Emergency (A&E) nurses who met subject’s inclusion criteria. Structured questionnaires, observation checklist and interview were used to collect the data. Sixty eight (82%) of A&E nurses participated in this study. The study found out that with higher nursing qualification and training on courses related to emergency care, knowledge and skills of A&E nurses on the initial management of acute poisoning is enhanced. A&E nurses with lower education level had a higher mean score of positive attitude compared with nurses with higher nursing qualification. Majority 60 (88.2%) of the A&E nurses indicated that, they required more training on the initial management of acute poisoning. Study recommends that A&E nurses should be trained on various types of poisoning including;assessment, clinical presentations and management to include gut decontaminations. In addition, refresher courses should be organised for those already trained. Flowcharts that will enhance easy identification and management of poisoned casualties should be put in place and utilized accordingly.

Statistics of Acute Aluminium Phosphide Poisoning in Fez, Morocco

Aluminium phosphide is a rodenticide widely used in agriculture to protect grains and foods. Poisoning with this product represents a real problem in developing countries, as an interested young people and it causes high mortality. Aims of this study are to analysis epidemiological aspects, clinics, therapeutic, outcome of this acute poisoning and determine the factors of mortality. It is a retrospective study, concerned 47 patients intoxicated by the Aluminium phosphide between January 2009 and December 2012. It represents 23.4% of all poisonings. The mean age was 24.5 years with a female predominance （63.8%）. The poisoning was in a suicidal goal in 95.7% of cases. The mean ingested quantity was 3 grams. The initial clinical picture was dominated by vomiting, abdominal pain, shock and disorders of consciousness in 57.4%, 48.9%, 31.9% and 21.3%, respectively. Electrocardiogram abnormalities were observed in 38.3% of cases. Increase of Troponin was observed in 27.7% of cases. 36.2% of patients were intubated and ventilated and 40.4% have been placed under vasoactive drugs. The mortality rate was 38.3%. The prognostic factors were： delay of management, potassium disorders, elevated of Troponin, hypotension, tachycardia, need for mechanical ventilation, vasoactive drugs and shock. To improve the prognosis, the management should be rapid and the governement should focus more on prevention, so the aluminium phosphide will not be avaible to general population.

Effects of hemoperfusion combined with hemodialysis on target organ damage in patients with acute paraquat poisoning

Objective: To investigate the effects of hemoperfusion combined with hemodialysis on target organ damage in patients with acute paraquat poisoning. Methods: A total of 42 patients with acute paraquat poisoning who were admitted and treated in our hospital between December 2013 and October 2017 were selected as the research subjects, and their therapies were reviewed and used to divide them into the control group (n=20) who received hemoperfusion alone and the combined treatment group (n=22) who received hemoperfusion combined with hemodialysis. The differences in the levels of liver and kidney function indexes in peripheral blood as well as lung function indexes in arterial blood were compared between the two groups of patients immediately after admission, after 1 d of treatment and after 3 d of treatment. Results: Immediately after admission, the differences in the levels of liver and kidney function indexes in peripheral blood as well as lung function indexes in arterial blood were not statistically significant between the two groups. After 1d of treatment and after 3 d of treatment, kidney function indexes Scr, BUN and β2-MG levels in peripheral blood of combined treatment group were lower than those of control group at corresponding time points respectively;liver function indexes ALT, AST, TB and ALP levels in peripheral blood were lower than those of control group at corresponding time points respectively;lung function indexes PaO2, BE and PCO3- levels in arterial blood were higher than those of control group at corresponding time points respectively whereas PaCO2 levels were lower than those of control group at corresponding time points respectively. Conclusion: Compared with hemoperfusion alone, hemoperfusion combined with hemodialysis is more advantageous in protecting the functions of liver, kidney, lungs and other target organs of patients with acute paraquat poisoning.

Epidemic Diseases and Chinese Medicine:Example of Severe Acute Respiratory Syndrome and COVID-19

Epidemic diseases,known and studied in China since antiquity,are one of the main chapters of the School of Exogenous Febrile Diseases(温病学派)•Along with the legends about epidemic demons,China has developed over the centuries a medical approach based on the teachings of Huang Di Nei Jing(《黄帝内经》Internal Classic),Nan Jing(《难经》Classic of Difficulties'),and Shang Han Lun(《伤寒论》Treatise of Harmful Cold).However,it was in the 17th century,after the great break of the Song,Jin,and Yuan eras that an innovative spirit Wu Youxing(吴有性)first foresaw the existence of microorganisms as we know them now.His Wen Yi Lun(《瘟疫论》Treatise on Pestilences)foreshadows an original approach to epidemic diseases,particularly emerging infectious diseases of the 21st century:severe acute respiratory syndrome 2003-2004 and the COVID-19 pandemic are perfect examples.In this first article,which will be followed by two others,we will examine the classical and modern Chinese definitions of these dreadful plagues.

A Qualitative Study of the Triage of Patients with Non-Traumatic Acute Abdomen

Objective: To explore the work experience of medical staff in the emergency department of a general hospital in the triage of patients with non-traumatic acute abdomen to formulate corresponding intervention measures and branch evaluation tools. Methods: With descriptive phenomenology as the research method, semi-structured interviews were conducted with the medical staff in a tertiary hospital in Nanjing from February 1st to 10th, 2023, and Colaizzi seven-step analysis was used to analyze the data. Results: A total of 17 emergency medical staff were interviewed in this study. Four themes were derived from the analysis of the data: the etiology of acute abdomen is complex, so it is difficult to categorize them: acute abdomen requires immediate treatment, but the treat will be delayed if the categorization is inaccurate;the high pressure of nurses and the accuracy in categorizing the patients are problems that should be addressed. Conclusion: The categorization of patients with non-traumatic acute abdomen is challenging. Therefore, it is necessary to carry out corresponding intervention and formulate appropriate departmental evaluation tools to improve the accuracy of categorization of patients with acute abdomen.

Expression of heat shock protein 70 in lung tissuesof acute paraquat poisoned rats and interventionof ulinastatin

BACKGROUND： Paraquat （PQ） is an effective herbicide and is widely used in agricultural production, but PQ poisoning is frequently seen in humans with the lung as the target organ. Clinically pulmonary pathological changes are often used to predict the severity and prognosis of the patients. In this study, we observed the expression of heat shock protein 70 （HSP70） in rat lung after PQ poisoning and to investigate the therapeutic effects of ulinastatin.METHODS： Seventy-two adult healthy SD rats were randomly divided into a control group （group A, n=24）, a poisoning group （group B, n=24）, and an ulinastatin group （group C, n=24）. The rat models of acute PQ poisoning were established by intra-gastric administration of 80 mg/kg PQ to rats of groups B and C, and the rats of group C were intra-peritoneally injected with 100 000 IU/kg ulinastatin 30 minutes after poisoning. The expression of HSP70 in lung tissue was observed, and W/D and histopathological changes in the lung tissue were compared 12, 24, 48 and 72 hours after poisoning. The expression of HSP70 in the lung tissue was assayed by using RT-PCR. All quantitative data were processed with one-way analysis of variance to compare multiple sample means.RESULTS： Compared to group A, the expression of HSP70 in the lung of rats in groups B and C increased signi？ cantly at all intervals （P〈0.05）. The pathological changes in lung tissue of rats with PQ poisoning included congestion, leukocytes in？ ltration and local hemorrhage, whereas those of group C were signi？ cantly lessened.CONCLUSION： Ulinastatin may ameliorate acute lung injury to some extent after PQ poisoning in rats by enhancing the expression of HSP70.

Factors influencing prehospital delay for patients with acute myocardial infarction

Objective To investigate the influencing factors for prehospital delay in patients with acute myocardial infarction (AMI). Methods A total of 807 consecutive patients with AMI who presented to the emergency department of Beijing Anzhen Hospital were analyzed. The influence of several potential risk factors on the prehospital delay time (PDT) was evaluated by comparing patients admitted more than 2 hours after onset of chese pain with those admitted within 2 hours after onset. Results Among 807 patients, 402 came to the hospital within 2 hours while the others arrived at the hospital after 2 hours. The median PDT was 130 min. Among the potential variables, advanced age, history of diabetes mellitus, occurrence of symptom at night and use of emergency medical service significantly affected PDT by multivariate analysis. Conclusion Interventions aimed at reducing the prehospital delay in AMI should primarily focus on the awareness of the risk and help-seeking behavior of patients.

Assessment of Counselling for Acute Diarrhoea in North-Eastern German Pharmacies—A Follow-Up Study Using the Simulated Patient Methodology

Aim: As the primary aim of this study, we analysed whether the quality of advice provided by pharmacies in the period between 2014 (baseline study) and 2017 (follow-up study) could actually be increased using a single written performance feedback given to each pharmacy in 2014. The secondary aim of the follow-up examination was to analyse whether the quality of advice differed depending on the professional group providing the advice. Methodology: To ensure the least possible distortion in the comparison between the baseline and the follow-up studies, the study design used for the follow-up examination in 2017 was not changed compared to the baseline examination in 2014. The data for the follow-up examination were therefore collected using the simulated patient method in all 21 pharmacies in a city in the north-east of Germany. Three female and two male test buyers used four different scenarios for self-medication of acute diarrhoea in all of the pharmacies (a total of 84 test purchases). Results: There were significant differences between the overall results from the baseline study (2014) and the follow-up study (2017) (Wilcoxon signed rank test;z = &ndash;2.065, p = 0.039, r = 0.225). In the overall average, the pharmacies in 2017 achieved only 2.7 (30%) of 9 possible points whereas in 2014 they achieved 3.3 (37%). The quality of advice between the professional groups did not show any significant differences (Kruskal-Wallis test: χ2(2) = 1.946;p = 0.378, r = 0.027). Conclusions: The quality of advice for acute diarrhoea in adults declined over time. A written performance feedback intended to improve the quality proved ineffective. Interventions with a far greater impact are required to achieve an improvement in the quality of advice provided.

Optimization of the Classic Transfer-Stacking Model Migration Algorithm: A Way to Solve Time-Varying Performance Degradation of Acute Kidney Injury Clinical Prediction Model

Acute Kidney Injury (AKI) is one of the most common acute and critical illnesses in general wards and intensive care units. Its high morbidity and high fatality rate have become a major global public health problem. There are often serious lags in clinical diagnosis of AKI. Early diagnosis and timely intervention and effective care become critical. The use of electronic medical record data to build an AKI risk prediction model has been proven to help prevent the occurrence of AKI. However, in actual clinical applications, the distribution of historical data and new data will continue to vary over time, resulting in a significant decrease in the performance of the model. How to solve the problem of model performance degradation over time will be a core challenge for the long-term use of predictive models in clinical applications. Aiming at the above problems, this paper studies the classic Transfer-Stacking model migration algorithm. Aiming at the lack of this algorithm, such as the loss of a large amount of feature information of the target domain and poor fit when integrating the model of the target domain, the Accumulate-Transfer-Stacking algorithm is proposed to improve it. Improvements include: 1) Optimize the input vector and model integration algorithm of Transfer-Stacking’s target domain model. 2) Optimize Transfer-Stacking from a single-source domain model to a multi-source domain model. The experimental results show that for the improved algorithm proposed in this paper when the data is sufficient and insufficient, the average AUC value of the model on the data of subsequent years is 0.89 and 0.87, and the average F1 Score value is 0.45 and 0.36. Moreover, this method is significantly better than the unimproved Transfer-Stacking algorithm and baseline method, and can effectively overcome the problem of data distribution heterogeneity caused by time factors.

Effect of coronary artery revascularization on in-hospital outcomes and long-term prognoses in acute myocardial infarction patients with prior ischemic stroke

Objective To investigate whether coronary artery revascularization therapies （CART）, including percutaneous coronary intervention （PCI） and coronary artery bypass grafting （CABG）, can improve the in-hospital and long-term outcomes for acute myocardial infarction （AMI） patients with prior ischemic stroke （IS）. Methods A total of 387 AMI patients with prior IS were enrolled consecutively from January 15, 2005 to December 24, 2011 in this cohort study. All patients were categorized into the CART group （n = 204） or the conservative medications （CM） group （n = 183）. In-hospital cardiocerebral events and long-term mortality of the two groups after an average follow-up of 36 months were recorded by Kaplan-Meier survival curves and compared by Logistic regression and the Cox regression model. Results The CART patients were younger （66.5 ± 9.7 years vs. 71.7 ± 9.7 years, P 〈 0.01）, had less non-ST segment elevation myocardial infarction （11.8% vs. 20.8%, P = 0.016） and more multiple-vascular coronary lesions （50% vs. 69.4%, P = 0.031）. The hospitalization incidence of cardiocerebral events in the CART group was 9.3% while 26.2% in the CM group （P 〈 0.01）. CART significantly reduced the risk of in-hospital cardiocerebral events by 65% [adjusted odds ratio （OR） = 0.35, 95% CI： 0.13-0.92]. By the end of follow-up, 57 cases （41.6%） died in CM group （n = 137） and 24 cases （12.2%） died in CART group （n = 197）. Cox regression indicated that CART decreased the long-term mortality by 72% [adjusted hazard ratio （HR） = 0.28, 95% CI： 0.064）.46], while categorical analysis indicated no s{gnificant dif- ference between PCI and CABG. Conclusions CART has a significant effect on improving the in-hospital and long-term prognoses for AMI patients with prior IS.

Medication rules in treating phlegm-heat syndrome of acute ischemic stroke based on data mining

Objective:To analyze the medication rule of Traditional Chinese Medicine(TMC)in treating acute ischemic stroke(AIS)with phlegm-heat syndrome based on date mining.Methods:All clinical studies of TMC treatment for phlegm heatexcess pattern stroke at acute stage were searched from SinoMed,CNKI,VIP,Wanfang,Pubmed.The retrieval time was from the establishment of each database to 27 April 2020.Establish database through"Ancient and Modern Medical record Cloud platform(V2.2.3)"software.SPSS20.0 and SPSS Modeler 18.0 software was used to explore clustering analysis and drug association rule analysis of high frequency drugs.Results:60 articles were finally included and 59 prescriptions were collected.The result shows that the commonly used drugs are mostly warm and cold,and the taste is mainly sweet and bitter.The main distribution of meridian tropism is stomach,liver and spleen.In these prescriptions,the frequently used drug pairs were“Trichosanthis fructus”,“Rhei radix et rhizoma”and so on.The association analysis results showed that“Arisaema cum bile-Rhei radix et rhizoma”had the highest correlation.The clustering analysis figured out 2 groups of the herbs.Conlusion:The TCM treatment of AIS should be based on the drugs of clearing heat,resolving phlegm and dredging viscera.Because most of these drugs are bitter and cold,we should pay attention to taking care of the spleen and stomach while expelling evil.

CLINICAL OBSERVATION ON THE TREATMENT OF ACUTE CEREBRAL INFARCTION WITH SCALP-ACUPUNCTURE

Abstract: In the present paper, the authors report the findings of scalp-acupuncture treatment of 50 cases of acute cerebral Infarction. A total of 100 patients were randomly divided into scalp acupuncture group (n = 50) and medication control group (n= 50). In the former group, penetration needling from Baihui (GV 20) to Qianding (GV 21) and from Shuaigu(GB 8) to Xuanli (GB 6) was performed, followed by conducting electroacupuncture (EA) stimulation; while in control group, intravenous drip of Ligustrazine injectio 120 mg plus 5% glucose solution 250 mL (once daily, with 14 days being a therapeutic course) was given in the first therapeutic course and then intravenous drip of Piracetum injectio (2 g plus 5% glucose or normal saline 250 mL, once daily, continuously for 14 days) conducted in the second therapeutic course. Results: After treatment, of the 50 cases in scalp acupuncture group, 26 (52%) were recovered basically, 15 (30%) had significant improvement, 7 (14%) had improvement and 2 (4%) failed in the treatment; while of the 50 cases in control group, 15 (30%) recovered basically, 17 (34%) had marked improvement, 16 (32%) had improvement and 2 (4%) failed in the treatment. The integral values of hemiplegia and aphasia of scalp acupuncture group were less than those of control group (P <0.01). It Indicates that the therapeutic effect of scalp acupuncture is superior to that of control group.

Classification of Bone Marrow Cells for Medical Diagnosis of Acute Leukemia

Leukemia is the cancer that starts in the blood cells due to the excess production of immature leucocytes that replace the cells with normal blood cells.Physicians rely on their experience to determine the type and subtype of Leukemia from the blood sample.Most people are misdiagnosed when it comes to its subtypes,the error rates can be up to 40%during the classification process.That too depends on the expertise of the physician.This research represents a Convolutional Neural Network based medical image classifier.The proposed technique can classify Leukemia and its five subtypes.State of the art deep learning and transfer learning techniques have been used,all of the network architectures are fine-tuned followed by feature extraction.This research can assist the pathologist in decision making or can be used for the process automation.The proposed methodology can give better results in terms of accuracy and is more effective than the hematologist’s visual classification in terms of time.
