ems. Preliminary field tests may be used for screening the debris on the explosion site. They include commercially available explosive vapor detectors and chemical color tests. Like post-explosion residues, personal items suspected to contain traces of explosives and hand-swabs, are often heavily contaminated. It is therefore of major importance that the analytical procedures have to include good screening, clean-up, and extraction methods. The main explosives dealt with in this chapter include nitroaromatic explosives, such as 2,4,6-trinitrotoluene (TNT) and 2,4,6, N-tetranitro-N-methyl aniline (tetryl), nitrate esters, such as ethylene glycol dinitrate (EGDN), glycerol trinitrate (nitroglycerin, NG), and pentaerythritol tetranitrate (PETN), and nitramine explosives, such as 1,3,5- trinitro-1,3,5-triazacyclohexane, (RDX) and 1,3,5,7-tetranitro-1,3,5,7-tetrazacyclooctane (HMX), as well as mixtures containing one or more of these explosives. Additional explosives include triacetone triperoxide (TATP) and ammonium nitrate (AN), NH4NO3.

Moringa oleifera which is also known as horseradish or drumstick tree is a rapidly growing, drought-tolerant tree that can tolerate poor soil conditions. It is presently broadly cultivated and has turned out to be naturalized in numerous geographical areas of the tropics. The objective of this study was to evaluate the growth performance and survivability of Moringa seed origins in the North Florida region of the United States of America. Seedlings were prepared in the George Conoly Greenhouse at the Florida A&M University, Tallahassee, FL. The seed origins were Ghana, Texas PKM1, Haiti PKM1, Colombia, Nigeria, Jamaica, Nigeria Local, Impex PKM1, Peela Medu, India EOA PKM1, and Belton. A randomized completely block design (RCBD) was used in this study to compare the performance of eleven seed origins of M. oleifera Height and Stem diameter. Nigeria Local had the best performance in terms of height for 2018 and 2019 growing seasons, 191.98 ± 7.42 cm and 123.19 ± 26.67 cm, respectively. Colombia had the best performance in terms of stem diameter for the 2018 and 2019 growing seasons, 2.6 ± 0 cm and 2.08 ± 0 cm, respectively. However, DMRT revealed that the height and stem diameter of the seed origins were not significantly different (p ≤ 0.05). Therefore, the results revealed that the alternative hypotheses (Ha) that the Moringa oleifera seed origins were significantly different in heights and stem diameter were rejected.

A case of post-operative agranulocytosis which occurred in a 66-year-old woman following surgery for endometrial carcinoma is reported. The agranulocytosis had a rapid onset, being detected on the first post-operative day. The causative agent, cefazolin was given to the patient intraoperatively. The agranulocytosis persisted until the 22nd postoperative day. A bone marrow biopsy performed on post-operative day four showed a left-shifted myeloid maturation pattern but not a maturation arrest. The pathogenesis of drug-induced neutropenia/agranulocytosis is discussed. It is postulated that reversible binding of cefazolin to albumin accounts for the prolonged duration of agranulocytosis.

Aim: To examine the relationship between the levels of HbA1c and hospital admission rates.Methods: We recorded HbA1c levels of all diabetic patients in Tripoli University Hospital over one year.Results: The mean HbA1c was 8.03%, with no difference between males and females. Over half of patients (56.5%) were admitted through their diabetes was well-controlled. Over half of the patients with type 1 diabetes (57/102, 55.9%) had a high HbA1c at admission compared to 42.1% of patients with type 2, who were mainly admitted with HbA1c level within the acceptable range set for this study. The HbA1c level was positively and significantly correlated with the length of hospital stay (R = 0.93, p = 0.000), and was significantly associated with hyperglycemia, diabetic ketoacidosis, coronary artery disease, limb ischemia, cataract, osteomyelitis, and non-alcoholic steatohepatitis.Conclusion: HbA1c is correlated significantly with hospitalization in type 1 diabetes but not in type 2.

Introduction: Modern pediatrics of disasters is built on 5 basic principles: integrity, structure, causality, dynamism, and hierarchy.Material and methods: Methodological approaches were used: systemic, complex, integration, functional, dynamic, process, normative, quantitative, administrative, and situational, and methods: historical, analytical, and comparison. Techniques were used: grouping, absolute and relative values, detailing, and generalization.Results: The algorithms of actions of the doctor of the children’s clinic in the event of a fire, the receipt of a call about the laying of explosives and the threat of explosion were considered, the scope of the provision of first qualified aid to the pediatric nursing team was clarified. The issues of the organization of the first qualified and specialized medical care, taking into account the anatomical and physiological characteristics of children and adolescents, as well as medical tactics for small-medium, and large disasters in rural areas and cities are discussed.Conclusion: Pediatrics of disasters is an independent section of organizational and medical work in emergencies and terrorist acts, providing specialized medical care for at least 25% of victims, who are children and adolescents. The training of doctors of a specialized children’s polyclinic is regulated by regulatory documents of the Russian Federation and the Republic of Komi, Orders of the Ministry of Health of the region, a municipal formation, and a medical institution in the field of civil defense and emergency situations. In case of minor emergencies and disasters within the city boundaries with the occurrence of a single or a small number of group losses, medical support repeats that in road traffic accidents, with the exception of the organization and conduct of medical triage. In rural areas, it is required to attract additional medical and nursing teams (emergency medical aid teams), created on the basis of medical institutions of the victim and neighboring areas. At the same time, a forced maneuver by the forces and means of territorial health care is necessary for the medical evacuation of a significant part of the affected children to specialized institutions (departments) located in cities. The provision of psychological and psychiatric assistance to children and adolescents in emergencies is carried out on the basis of its basic modules (departments and offices of psychological and psychiatric assistance, and advisory mobile team of psychological and psychiatric assistance, anonymous psychological and psychiatric assistance by telephone).

Introduction: Preparing a report and passing certification for a qualification category is one of the forms of improving the professional level of each medical worker.Material and methods: The analysis of 5 qualification works of a psychiatrist (1997, 2002, 2008, 2013, and 2018) was carried out for the mandatory requirements for the preparation of documents when they were submitted to the Attestation Commission on the assignment of a qualifying medical category in psychiatry and formation methodological approaches to their implementation. The depth of research was 27 years.Results: Methodological approaches to the design of 11 mandatory sections provided for in the certification work of a psychiatrist presented for the award of a qualification category were considered.Discussion: The attitude to the Administrative Regulations for the provision of state services for the assignment of a qualification category to specialists engaged in medical and pharmaceutical activities should be revised in terms of its synchronization with the official duties of a doctor.Conclusion: The dynamic development of the regulatory, organizational, methodological, and scientific aspects of medicine and psychiatry, in particular, in the period of active digitalization of healthcare, requires periodic corporate discussion and correction of the Administrative Regulations for the provision of public services for assigning a qualification category to specialists engaged in medical and pharmaceutical activities.Attention should be paid to the insufficient statistical processing of the submitted materials by applicants for the assignment of the 1st and highest categories, the lack of calculations, references, and comparisons of confidence intervals, and the reliability of the study.Preparing a report and passing certification for a qualification category can be the first step in introducing a practitioner to scientific work through the generalization of personal work experience, worthy of speaking at a scientific and practical conference at the level of LU and the region and publishing abstracts in collections and scientific and practical journals.The proposed methodological approaches are purely advisory in nature and can be used by psychiatrists when working on a qualification category at their discretion.

Due to extensive COVID-19 prevention measures, millions of tons of chemicals penetrated the natural environment. Alterations of viruses in the environment, the neglected perceiver of environmental fluctuations, remain obscure. Chemicals especially trihalomethane restrained the virus community diversity. Segments of SARS-CoV-2 RNA have been detected near hospitals that suggesting the environment as a missing link in the transmission route. Human viruses lurking in the environment were potentially activated by pandemic prevention chemicals, warning an overlooked burden to human health. This letter warns of the risk of activation of human viruses in the environment following the overuse of COVID-19 prevention devices and emphasizes the long-term monitoring of environmental viruses in the post-pandemic period.

The paper is devoted to the problem of high-energy solid-state laser arms, demonstrating the highest efficiency in the terms of weight and sizing. We can predict a very bright future for such laser systems as a significant means of defeating the enemy. The problem of scalability for such an approach based on fiber laser technology is the key question of our days for many companies of the world. At the same time, it is clear that a tactical LW based on solid-state technology with a weight factor of 5 kg / kW with the total weight of a laser complex significantly less than a ton can be created. But the level of output power around 500 kW is very close to the limit for the fiber technology...

The commonest etiology of acute kidney injury (AKI) is Sepsis that results in an escalation of morbidity and mortality in the hospital intensive care units. Existentially, the therapy of septic AKI rather than being definitive or curative is just supportive, without tackling the pathophysiology. Usually, Sepsis gets correlated with systemic inflammation, along with the escalated generation of Reactive oxygen species (ROS), in particular superoxide. Simultaneously liberation of nitric oxide (NO) subsequently reacts with the superoxide, thus, resulting in the generation of reactive nitrogen species (RNS), that is mostly peroxynitrite. This sepsis stimulated generation of ROS in addition to RNS might cause a reduction in the bioavailability of NO that modulates microcirculation aberrations, localized tissue hypoxia as well as mitochondrial impairment, thus starting a vicious cycle of cellular damage which results in AKI. Here we conducted a systematic review utilizing search engine PubMed, Google scholar; Web of science; Embase; Cochrane review library utilizing the MeSH terms like septic AKI; ROS; inducible nitric oxide synthase (iNOS); nicotinamide adenine nucleotide phosphate(NADPH)oxidase complex; Oxidative stress; Renal medullary hypoxia; Hypoxia inducible factor1; hypoxia responsive enhancer A; mitochondrial impairment; Intrarenal oxygenation; urinary oxygenation; erythropoietin gene; RRT; NAC; Vitamin C from 1950 to 2021 till date. We found a total of 6500 articles out of which we selected 110 articles for this review. No meta-analysis was done. Thus here we detail the different sources of ROS, at the tie of sepsis, besides their pathophysiological crosstalk with the immune system, microcirculation as well as mitochondria that can result in the generation of AKI. Furthermore, we detail the therapeutic utility of N-acetylcysteine (NAC), besides the reasons for its success in ovine as well as porcine models of AKI. Moreover, we discuss preclinical along with clinical for evaluation of Vitamin C’s antioxidant effects as well as pleiotropic effects as a stress hormone that might aid in abrogation of septic AKI.

Background: Currently there are three available formulations of tacrolimus in the United States; these include immediate-release capsules (TAC-IR), extended-release capsules (TAC-XL),and extended-release tablets (TAC-XR). Previous studies have demonstrated non-inferiority between the three formulations in terms of efficacy. The purpose of this study was to compare three formulations of tacrolimus (TAC) and assess differences in time within the therapeutic range (TTR) and variability in levels. Results: Renal transplant recipients from January 2013 to October 2017 were retrospectively identified for analysis. Deviation from standard TAC protocol or formulation changes excluded patients. The primary outcome compared percent TTR (TTR %) among 3 TAC formulations over the first 90 days post-transplant. TTR was calculated using the Rosendaal method. Secondary outcomes included differences in TAC levels, TAC dose, eGFR, rejection, patient and graft survival between the TAC formulations. TAC-XR demonstrated a significantly higher TTR % compared to TAC-IR and TAC-XL (62.8% vs. 53.3% vs. 60.9%, p = 0.048). In post-hoc analysis, TAC-XR had a higher TTR % compared to TAC-IR (p = 0.065), which approached statistical significance. Average TAC levels, weight-normalized TAC doses, median dose-normalized TAC levels, rejection rates, eGFR, and graft or patient survival were similar among groups. Conclusion: In the early transplant period, TTR was significantly different among the groups. TAC-XR demonstrated numerically superior time within the therapeutic range. Patient-specific factors such as race, obesity, genetic polymorphisms may impact this variability and clinical outcomes. Further analysis is necessary to understand the effect of each patient-specific factor on TAC exposure.

Background: Globally 1.13 billion people were living with hypertension, Out of this two-thirds of them were living in low and middle-income countries. In Ethiopia, Non-Communicable Disease deaths are estimated at around 42%. However, it remains widely undetected and poorly controlled. To resolve these, lifestyle modification approaches that are often overlooked are the cornerstone of the prevention and management of hypertension. Objective: To assess lifestyle modification practice and associated factors among hypertensive patients in selected hospitals in West Arsi Zone, Oromia Regional, Ethiopia December 7 to 21, 2019. Method: Hospital-based cross-sectional study was conducted in the selected public hospital among 299 hypertensive patients. Systemic random sampling methods were used to select the study participants. Data were collected by face-to-face interviews using a structured questionnaire by trained data collectors. Data were analyzed using descriptive statistics and multivariate logistic regression method to identify predictors of the outcome (p < 0.05). Results: Of the total participants, only 25.2% (95% CI: 18.8-32.9) of the patients were practiced recommended lifestyle modifications. Patients Age older than 65 years (AOR = 2.9, 95% CI: 1.17 - 7.0), the patients with 2-5 years’ time since diagnosed hypertension (AOR = 0.26, 95% CI: 0.07 - 0.9), multiple co-morbidity (AOR = 2.7, 95% CI: 1.25 - 5.8,) and their knowledge on hypertension management (AOR = 14.6, 95% CI: 4.6 - 45.9) have an independently associated with recommended lifestyle modification. Conclusion: Lifestyle modification practices among hypertensive patients were low in this study. Age, comorbidity, time since diagnoses of hypertension, and knowledge of lifestyle were identified as predictors of the outcome.
