Pathological Lung Lesions of COVID-19 and Opioid Use Disorder: A Post-Mortem Lung and Toxicology Examination of 43 Decedents

The COVID-19 pandemic has continued from 2019 to current times, exacerbating existing epidemics since its beginning. Pathologic lung lesions in acute cases have consisted of hyaline membrane disease and microthrombi. More severe cases have pathologic lesions of alveolar and bronchiolar epithelial necrosis, lymphocytic interstitial infiltrate, and peribronchiolar and perivascular lymphocytic infiltrate. The opioid epidemic is one epidemic exacerbated by COVID-19. Those with opioid use disorder (OUD) are more likely to have compromised lung function, of which infection with the SARS-CoV-2 virus can worsen. The combined symptoms lead to an increased risk of overdose. In addition to anatomical risks, those with OUD require person-to-person contact to obtain opioids. This enhances the spread of COVID-19 and increases the risk of acquiring the disease. Pathological findings in those with chronic OUD can contain fluorescing talc powder with multinucleated giant cells and granulomas in the lung tissue. Twenty-one positive cases and twenty-two negative cases were collected from COVID-19 suspicious decedents in Marion County Coroner’s Office. Toxicology screens and COVID-19 RT-PCR tests were run on each of the 43 decedents. Microscopic evaluation was done by hematoxylin and eosin (H & E) and Masson’s Trichrome stains. The age range of those collected was 3 to 81 years. The ethnicities were 1 Asian, 8 African American, 1 Cuban, 3 Hispanic, 29 Caucasian, and 1 unknown. The male to female ratio was 3.8:1. The histological features found in this study were alveolar and bronchiolar epithelial necrosis, lymphocytic interstitial infiltrates, perivascular and peribronchiolar lymphocytic infiltrate, fibrosis, microthrombi, and hyaline membrane. Fluorescing talc was seen in 5 cases with granulomas and multinucleated giant cells. Toxicology reports showed 11 drug-related deaths, with cocaine, methamphetamine, alcohol, fentanyl, morphine, acetyl fentanyl, and sertraline as the causative agents.

Analysis of the feasibility of a forensic chemical investigation in clobazam poisoning

The study objective was to determine the relevance of methods to detect clobazam poisoning during the forensic and chemical toxicological examination. The lack of a systematic approach to clobazam identification and assay as a part of forensic chemical and chemical toxicological analyses was demonstrated. The published data on the study of clobazam in biological objects are inconsistent and incomplete, precluding the conduction of focused forensic chemical and toxicological investigations on biological objects with required validity. Various methods of forensic chemical and toxicological investigation of clobazam in biological objects were studied and presented. Data are presented on various physicochemical test methods (TLC, HPLC, UV spectrometry, GC, and GC-MS) for clobazam detection.

Medicolegal Implications of Fatalities Because of Entanglement in the Augers of Feed Mixer Wagons.

Feed mixer or total mixed ration mixer wagons are powerful agricultural machines used to shred and mix silage with other ingredients and deliver it direct to the feeding troughs on livestock farms. Fatalities involving these feed mixers may occur when operators become trapped in the augers or, less frequently, are crushed by moving wagons. Death can occur very rapidly because of dismemberment, multiple lesions, or crushing. The aim of this review is to focus on the diagnostic evaluations that need to be performed to confirm that the death was accidental and to exclude a hypothesis of murder or suicide. Forensic investigations in such cases must involve the detailed analysis of the death scene and the mechanical characteristics of the machinery with an accurate postmortem and toxicological examination.

Dietary alcohol exacerbates the hepatotoxicity induced by pyrrolizidine alkaloids: Hazard from food contamination

Pyrrolizidine alkaloids (PAs) are the most common plant-derived toxins with emerging evidence to contaminate soil, water, nearby plants and derived food products. Outbreaks of human poisoning cases, due to the ingestion of PA-contaminated food, have been reported in various countries including Ethiopia. This study first investigated the contamination of PAs in retail honey in Ethiopia. A striking 77% of honey samples (27/30) were found to contain PAs with the content ranging over 1.5–323.4 μg/kg. Notably, these PAs were also found as contaminants in mead, an alcoholic beverage made from local honey, indicating the transfer of PAs from the primarily contaminated honey into mead. Further toxicological examinations revealed that long-term PA exposure caused vasculature damage, fibrosis, and steatosis in mouse livers, and co-exposure to dietary alcohol exacerbated the PA-induced chronic hepatotoxicity. Furthermore, the study revealed that moderate alcohol intake did not affect the initiation mechanism (hepatic cytochrome P450-mediated bioactivation) of PA-induced hepatotoxicity but significantly disturbed hepatic glutathione homeostasis, thereby increasing oxidative stress in mouse liver and enhancing PA-induced hepatotoxicity. Our findings exemplify the carry-over of PA contamination through the food chain. Precautionary interventions are warranted on the hazardous effects of dietary exposure to PAs, particularly with concomitant alcohol consumption.

Modern possibilities of forensic medical evaluation and differentiation of acute intoxications

This article analyzes modern scientific sources on the problems of detection of toxic substances in the human body, considers the existing methods of toxicological examination used in practical forensic medicine to establish and differentiate acute intoxications with various chemical compounds. Despite the presence of a large number of methods of toxicological analysis, forensic diagnosis of poisoning is often complicated due to lack of data on the circumstances of the event, clinical data of poisoning, pathognomonic signs of poisoning, the difficulty of interpreting the results.
 Conclusions. When interpreting the results of a toxicological study should always take into account the circumstances of the case and factors that may have influenced the change in the concentration of toxic substances. There is a need to develop and implement in practice forensic toxicology laboratories fundamentally new diagnostic approaches for the detection of toxic substances and the differentiation of types of poisoning.

Cigarette Smoking as a Predictor of Male DUI Recidivism.

This study aimed to investigate the predictors of recidivism in first-time driving under the influence (DUI) offenders, analyzing variables derived from medico-legal and toxicological examinations. The research was structured as a comparative study for the period 2012–2019. DUI offenders with a blood alcohol concentration >0.5 were included in the study. The case group consisted of recidivist offenders, while the comparison group consisted of first-time offenders. Personal data, socioeconomics, and parameters linked to the DUI were compared between the two groups. Significance was determined by chi-square and Mann–Whitney tests. To prevent confounding effects, multivariate binary logistic regression analysis was performed. Our sample encompassed 1678 subjects (196 in the case group, 1482 in the comparison group). Gender, driving license category, education, and tobacco use resulted in significant differences between the groups. In a model including age at DUI, education, and smoking habit as independent variables, higher educational levels (high school, bachelor’s) and older age protected against recidivism, whereas smoking >20 cigarettes/day was an independent risk factor for recidivism. Recidivist offenders have specific characteristics indicating different therapeutic programs and carefulness in driving license regranting. A higher tobacco consumption in recidivists suggests that the use of this substance could influence the risk of DUI for reasons that will need to be explored.

Complex suicide-A novel case report and a brief review of literature

Background:Suicides are usually known to be either simple or complex, the latter which is defined as a combination of more than one method. Additionally, complex suicide can be practiced in an unplanned manner where several methods are used, consecutively, when the first method has not achieved the desired outcome. The procedure usually gets changed after the first method chosen failed, was working slowly, or proven to be overly painful. The rotation between failed suicidal acts causes difficulties in determining the manner and the mode of death. Method: In the present study, we will discuss some of the relevant previous studies regarding complex suicide and a systematic approach to managing such cases from a medicolegal perspective. Besides, an unusual case of complex suicide, which was handled in 2018 in the Kuwaiti Forensic Medicine Department, will be presented. She is a middle-aged female, domestic worker, who was found dead in the bathroom, with secured inlets and outlets from inside. She was incompletely hanged with multiple neck, chest, and abdominal cut wounds, apart from bilateral wrist cut. Furthermore, bloody knife, razor and razor-blade were found inside the basin. Result and conclusion: After a complete autopsy, forensic pathology and toxicology examination were done, the forensic and crime scene reports together with the criminal investigations were declared. Consequently, the case was reported as a complex suicide case and the cause of death was haemorrhagic shock after lung stabbing. The case represents a novel complex suicide with self-stabbing, wrist cutting and hanging

Factors associated with methamphetamine use in Japanese people who died of unnatural causes: Analysis using forensic autopsy reports

This study aimed to examine factors related to methamphetamine use in Japanese people who died of unnatural causes. This study used a cross-sectional design. A total of 3343 forensic autopsy reports were obtained from two forensic medicine departments in the Kanto region of Japan. We classified the decedents who underwent forensic autopsies into methamphetamine/amphetamine (MA) and undetected (comparison) groups based on toxicological examination. We matched the decedents in the MA group with those in the comparison group at a 1:4 ratio based on sex and age. The variables, including gang members, criminal records, tattoos, body mass index, infections, concurrent psychotropic drug use, and cause of death, were compared between the groups. Of the 3343 decedents, we matched 109 in the MA group with 436 in the comparison group. Methamphetamine use was significantly associated with gang membership (13.8% vs. 3%, p < 0.001), criminal records unrelated to methamphetamine (47.7% vs. 13.8%, p < 0.001), tattoos (29.2% vs. 6.4%, p < 0.001), and hepatitis C virus infection (48.0% vs. 3.6%, p < 0.001). One-third of the patients in the MA group died from poisoning. This is the first study to show the physical and social characteristics associated with methamphetamine use in Japanese people who died of unnatural causes. Our results could be extended to people with methamphetamine use disorder at risk of death and enable the development of policies and practices to provide necessary intervention in a timely manner.

The assessment of the time-lapse between toxic exposure and examination in the Toxicology Department in pediatric severe acute poisoning

The exposure of the pediatric population to xenobiotics is an important public health problem because children are particularly vulnerable to the unfavorable consequences of intoxications due to their age-related peculiarities, having limited physiological reserves, and poorly developed metabolic pathways. Numerous studies emphasize the importance of targeted therapeutic intervention and as soon as possible in patients with severe acute intoxications that associate signs of cardiogenic shock due to the severity of cases and the risk of adverse evolution. This paper presents a statistical analysis of the time-lapse impact between exposure to the toxicant and the toxicological examination on the patient's prognosis. Its purpose is to identify both qualitative and quantitative correlations between a series of parameters associated with unfavorable evolution and the time elapsed until the specific toxicological management is performed.

Ecotoxicological Effects of Bimetallic PdNi/MWCNT and PdCu/MWCNT Nanoparticles onto DNA Damage and Oxidative Stress in Earthworms.

Bimetallic nanoparticles are synthesized using two different metal elements and used recently in many fields. However, limited studies related to the ecotoxic effects of nanoparticles available in the literature. The purpose of this study is to synthesize and characterize bimetallic PdCu/MWCNT and PdNi/MWCNT NPs and investigate their ecotoxic effects on earthworms. For this purpose, we injected approximately 20 µL of various concentrations of bimetallic PdCu/MWCNT and PdNi/MWCNT NPs (1, 10, 100, 1000, and 2000mg/L) into the coelomic space of earthworms. We evaluated survival rate, malformations, reactive oxygen species (ROS) level, 8-OHdG content, and histopathological changes in earthworms at the 48th hour after exposure. PdCu/MWCNT and PdNi/MWCNT NPs were characterized by scanning electron microscope (SEM), transmission electron microscope (TEM), X-ray diffraction (XRD) pattern, and Raman-scattering spectroscopy. Toxicological examinations showed that PdCu/MWCNT NPs reduced the survival rate of earthworms (2000mg/L, 84%) and caused various malformations (various lesions, thinning, swelling, and rupture), but nonsignificant effects of survival rate and malformations were observed in earthworms using PdNi/MWCNT NPs. The histopathological examinations of earthworm tissues exposed with PdNi/MWCNT determined that tissues in all treatment groups had a normal histological appearance. However, at a concentration of 2000mg/L of PdCu/MWCNT NPs, atrophy in the longitudinal muscle layer and less degenerative cells in the epidermis layer were observed in earthworm tissues. It was determined that PdNi/MWCNT and PdCu/MWCNT NPs caused significant increases in ROS levels and 8-OHdG activity in earthworm tissues after 48h. Finally, our results demonstrated that the toxicity of PdNi/MWCNT NPs was detected to be lower than PdCu/MWCNT NPs. However, both nanoparticles may pose a toxicological risk at high concentrations (1000 and 2000mg/L). These findings will provide valuable information to studies on the use of PdNi/MWCNT NPs in wastewater treatment systems, industrial and medical fields, which have been determined to have less ecotoxicological risk.

Evaluation of Methadone Consumption Rate Based on Post-mortem Toxicology Examinations in Cases of Drug-related Deaths in Iran: 2015-2017

Background: Given the increasing prevalence of methadone overdose and the growing number of deaths in Iran, the present study was conducted to determine the mortality rate of methadone detected in the cadavers brought to the Forensic Medicine Organization between 2015 and 2017. Methods: This cross-sectional study was performed on 7,486 cases of substance abuse deaths registered in the Forensic Medicine Organization during 2015-2017. In order to investigate the drug abuse, samples collected from the cadavers were initially examined for their drug contents, such as methadone, by standard screening methods and then confirmed by Thin Layer Chromatography (TLC). Using two checklists, the information collected about each cadaver consisted of the identity, autopsy and laboratory data. After data collection, they were entered into the Stata software version 14 MP. Results: The cadavers’ mean age was 36.6±12.6 years. Over the 3-year duration of the study, the standardized mortality rate increased from 35 to 39 cases per million per year. Of these cases, 6066 were randomly assigned to toxicology, 50.1% had used methadone one month before their death. Approximately 75% of the methadone abusers had taken another drug simultaneously, mostly morphine or methamphetamine. Conclusion: Considering the relatively high prevalence of methadone detected post-mortem, monitoring for methadone entry into public market and identifying the death-related factors in the drug abusers are considered as significant measures to improve upon the current alarming situation in the Iranian society.

Preliminary study on impacts of polystyrene microplastics on the hematological system and gene expression in bone marrow cells of mice

Microplastics (MPs) are currently a global environmental pollutants and health hazards that caused by MPs cannot be ignored. However, studies on MP toxicity in mammals are scare. Here, we investigated the effects of two doses (0.1 mg and 0.5 mg) of 5 µm polystyrene microplastic (PS-MP) particles on the hematological system of mice through traditional toxicology experiments and assessed the related potential biological mechanisms using transcriptome sequencing analysis. The toxicological examinations showed that the 0.5 mg dose significantly decreased white blood cell count, increased Pit count, and inhibited the growth of colony-forming unit CFU-G, CFU-M and CFU-GM. Compared with the control group, there were 41 differentially expressed genes (DEGs) in the 0.1 mg-treated group and 32 significantly changed genes in 0.5 mg-treated group. Of note, eight genes were found to be significantly altered in both the PS-MP-treated groups. Gene ontology analysis showed that DEGs were mainly involved in T cell homeostasis, response to osmotic stress, extracellular matrix and structure organization, and metabolic process of NADP and nucleotides. In addition, pathway analysis revealed that the Jak/Stat pathway, pentose and glucuronate interconversions, nicotinate and nicotinamide metabolism, biosynthesis of unsaturated fatty acids, and the pentose phosphate pathway were involved in PS-MP-induced toxicity in mice. These results indicated that PS-MP exposure can cause hematotoxicity to some extent, impact gene expression, and disturb related molecular and biological pathways in mouse bone marrow cells. Our study provides fundamental data on the hematotoxicity of PS-MPs in terrestrial mammals that will help to further assess the corresponding health risks in these mammals.

Association of US Nurse and Physician Occupation With Risk of Suicide

Nurses are the largest component of the US health care workforce. Recent research suggests that nurses may be at high risk for suicide; however, few studies on this topic exist. To estimate the national incidence of suicide among nurses and examine characteristics of nurse suicides compared with physicians and the general population. This retrospective cohort study used US data from 159 372 suicides reported in the National Violent Death Reporting System from 2007 to 2018. With the use of workforce denominators, sex-specific suicide incidence estimates were generated among nurses, physicians, and the general population (age, ≥30 years). Associations between clinician type and method of suicide and results of toxicology examination at death were calculated, adjusted for sociodemographic characteristics. Statistical analysis was performed from October 16, 2020, to January 10, 2021. Occupation as a nurse or physician. Suicide incidence and characteristics associated with suicides. A total of 2374 suicides among nurses (1912 women [80.5%]; mean [SD] age, 52.8 [11.8] years), 857 suicides among physicians (723 men [84.4%]; mean [SD] age, 59.8 [15.3] years), and 156 141 suicides in the general population (121 483 men [77.8%]; mean [SD] age, 53.1 [14.7] years) were identified. Overall, suicide was more common among nurses compared with the general population (sex-adjusted incidence in 2017-2018, 23.8 per 100 000 vs 20.1 per 100 000; relative risk, 1.18 [95% CI, 1.03-1.36]). Among women in 2017-2018, the suicide incidence among nurses was 17.1 per 100 000 (506 among 2 966 048) vs 8.6 per 100 000 (8879 among 103 731 387) in the general female population (relative risk, 1.99 [95% CI, 1.82-2.18]). In absolute terms, being a female nurse was associated with an additional 8.5 suicides per 100 000 (95% CI, 7.0-10.0 per 100 000) compared with the general population of women. By sex, physician suicide rates were not statistically different from the general population other than among female physicians in 2011-2012 (11.7 per 100 000 [95% CI, 6.6-16.8 per 100 000] female physicians vs 7.5 per 100 000 [95% CI, 7.2-7.7 per 100 000] general population; P = .04). In terms of the characteristics of suicides, clinicians were more likely to use poisoning than the general population; for example, 24.9% (95% CI, 23.5%-26.4%) of nurses used poisoning compared with 16.8% (95% CI, 16.6%-17.0%) of the general suicide population. The presence of antidepressants, benzodiazepines, barbiturates, and opiates was more common among clinician suicides than suicides in the general population. This study suggests that, in the US, the risk of suicide compared with the general population was significantly greater for nurses but not for physicians. Further research is needed to assess whether interventions would be associated with benefit in reducing suicide risk among nurses.

Chinese expert consensus on diagnosis and treatment of acute thallium poisoning (2021)

Acute thallium poisoning is relatively rare, which usually caused by eating by mistake or poisoning. This kind of poisoning attracts social attention. Its atypical clinical symptoms can result in misdiagnosis, mistreatment and poor prognosis. Most patients with acute thallium poisoning can be cured after early toxicological examination, timely blood purification or Prussian blue and symptomatic treatment. To diagnose and treat the disease correctly and timely, the Chinese Society of Toxicology Poisoning and Treatment of Specialized Committee and the Poisoning Group of Emergency Medicine Branch of Chinese Medical Association, together with the Poisoning Treatment Center of the Army, invited experts in the field of acute thallium poisoning to analyze, discuss and summarize the diagnosis and treatment to formulate the Chinese expert consensus on diagnosis and treatment of acute thallium poisoning (2021).

Comparison of Gastric-ulcerogenecity Effect of Methanolic Extract of Capparis spinosa and Indomethacin in Rat

Background: Several plants are used as analgesic in traditional medicine. Capparis spinosa (C. spinosa) is widely used for the treatment of gout and rheumatic arthritis. The previous studies have reported the antinociceptive effects of this plant. Objectives: The study was aimed at examining the C. spinosa’s gastric-ulcerogenecity effect in comparison to indomethacin. Methods: The percolated extract of C. spinosa and Indomethacin were orally administered to the rats at 50,100, 200, and 400 mg/kg doses, which were slaughtered after 4 hours. The stomach was detached, and 10 mL of 2% formalin was injected into it to fix the gastric wall internal layer. The stomach was then split by cutting along the greater curvature, and the lacerations in the glandular section examined. J-score was used to determine ulcer index. Results: The results indicated that percolated extract of C. spinosa administered orally in antinociceptive dosage and even 2,4 and 8 folds did not cause a gastric ulcer (J-score = 0) compared to indomethacin (J-score = 46 to 253) (P &lt; 0.05). Conclusions: Concerning the favorable analgesic effect of C. spinosa and lack of gastric ulcerogenecity effects, it seems to be a suitable choice for more pharmacological and toxicology examinations to use as analgesic.

Intracerebral Haemorrhage Caused by Endosulfan Intoxication: A Case Report

Introduction: many chemical substances used in industry, households, agriculture, often result in bad side effects to people and environment. As an agricultural country, the frequency of the use of pesticides in Indonesia is quite high since those chemical substances are still badly needed by the people for their farming. The bad side effects should strongly be avoided. Related with the disadvantages or dangers of those, especially pesticides. It is often found that a sudden death can be related with intoxication. It is sometimes difficult to differentiate them, whether if caused by disease, violence or intoxication. During 2008-2018 extra toxicological examination performed in the Forensic Laboratory of Toxicology in East Java Regional Police Headquarter in the period of 2008 up to 2018 indicated 44% of 25 cases were dominated by intoxication, which were mostly caused by propoxur intoxication (carbamate insecticide) 90 % and by endosulfan 10%. It means that endosulfan as the restricted pesticides can be the cause of death, wether by accidental action or even homicide and suicide action. Objective: To be able to analyze the changes or the clinical effects due to endosulfan intoxication, especially in death acutely which shown the intracerebral haemorrage from the death. Method: case report of the sudden death on women suspected poisoning by endosulfan. Conclussion: Symptoms of acute endosulfan poisoning include hyperactivity, tremors, convulsion, lack of coordination, staggering, difficulty of breathing, nausea/vomiting, diarrhea, and in severe cases, unconsciousness and many cases of sub lethal poisoning have resulted in permanent brain damage.

Nanotheranostics: A Possible Solution for Drug-Resistant Staphylococcus aureus and their Biofilms?

Staphylococcus aureus is a notorious pathogen that colonizes implants (orthopedic and breast implants) and wounds with a vicious resistance to antibiotic therapy. Methicillin-resistant S. aureus (MRSA) is a catastrophe mainly restricted to hospitals and emerged to community reservoirs, acquiring resistance and forming biofilms. Treating biofilms is problematic except via implant removal or wound debridement. Nanoparticles (NPs) and nanofibers could combat superbugs and biofilms and rapidly diagnose MRSA. Nanotheranostics combine diagnostics and therapeutics into a single agent. This comprehensive review is interpretative, utilizing mainly recent literature (since 2016) besides the older remarkable studies sourced via Google Scholar and PubMed. We unravel the molecular S. aureus resistance and complex biofilm. The diagnostic properties and detailed antibacterial and antibiofilm NP mechanisms are elucidated in exciting stories. We highlight the challenges of bacterial infections nanotheranostics. Finally, we discuss the literature and provide “three action appraisals”. (i) The first appraisal consists of preventive actions (two wings), avoiding unnecessary hospital visits, hand hygiene, and legislations against over-the-counter antibiotics as the general preventive wing. Our second recommended preventive wing includes preventing the adverse side effects of the NPs from resistance and toxicity by establishing standard testing procedures. These standard procedures should provide breakpoints of bacteria’s susceptibility to NPs and a thorough toxicological examination of every single batch of synthesized NPs. (ii) The second appraisal includes theranostic actions, using nanotheranostics to diagnose and treat MRSA, such as what we call “multifunctional theranostic nanofibers. (iii) The third action appraisal consists of collaborative actions.

Overview of Forensic Toxicology

Scientific toxicology is the utilization of toxicology and teaches like logical science, pharmacology and clinical science to help clinical or legitimate examination of death, harming, and drug use. The essential worry for legal toxicology isn't the legitimate result of the toxicological examination or the innovation used, yet rather the acquisition and translation of results. A toxicological investigation should be possible to different sorts of tests. A measurable toxicologist should think about the setting of an examination, specifically any actual manifestations recorded, and any proof gathered at a crime location that may limit the inquiry, for example, pill bottles, powders, follow build-up, and any accessible synthetics. Furnished with this data and tests with which to work, the criminological toxicologist should figure out which poisonous substances are available, in what focuses, and the plausible impact of those synthetics on the individual.
