Carbon monoxide (CO) is a toxic gas produced as a result of incomplete combustion of organic materials. The source of CO production is very common especially in nations that depend on power generating sets for electricity. Chronic disease is non-communicable and usually takes a longer time to manifest. Examples are kidney failure, diabetes mellitus, hypertension, cancer, and cardiac arrest. These diseases are now very common in society, not sparing the youthful population that was rare ab initio. The major difficulty in the containment of chronic diseases is the inability to establish a definitive causative agent. The definite causative agent is important in public health and management of chronic diseases. Preventive medicine is anchored on establishing the causative agent of a disease. Without knowing the causative agent of a disease, the path to prevention becomes very cumbersome. The knowledge of the causative agent of a disease is the bedrock of preventive medicine and public health. Several reasons such as lifestyle modification, hereditary, climate change, nutrition or aging have been adduced as the cause of chronic diseases. These reasons are quite weak and not definite. The exact causative agent(s) of chronic diseases is a conundrum that needs a deliberate study and review so as to enhance definite diagnosis, preventive measures and appropriate therapeutic intervention. Measurement of biochemical and haematological parameters are employed in disease diagnosis and management. Alterations of these parameters are used to identify chronic diseases and also form part of an alarm system of a potential breakdown of the normal functioning of the body. The effect of chronic CO intoxication on these parameters could be of importance in establishing causative agent(s) of diseases that are for long opaque and non-definite. This review was therefore designed to interrogate various narratives, meta-analysis, and researches on this subject. Explicit knowledge of the pattern or presentation of biochemical and haematological parameters arising from chronic CO intoxication could be of great importance in preventive medicine, disease diagnosis and appropriate therapeutic intervention.

Carbon monoxide is a toxic gas that is colourless, odourless, and has the potential to cause momentaryhypoxia by bonding with heme-inspired proteins. Because of these properties, it causes the highest number of toxications. Due to its properties, this gas causes damage to the nervous and cardiovascular system. The development of anoxia is associated with the impact on the system of oxidative phosphorylation in mitochondria and the development of oxidative stress in the body. The body produces a small amount of carbon monoxide as a result of erythrocyte breakdown. Picomolar concentrations of carbon monoxide even have anti-inflammatory, antiapoptotic,cytoprotective and antiproliferative properties. Kidney is one of the first organs,that responds to the occurrence of hypoxia, are responsible for the removal of products of metabolism and toxicants, including ethanol. For the study, the blood and urine samples were taken from patients with acute intoxication. The amount of methemoglobin in the blood was determined by spectrophotometric method. The concentration of ethanol in blood and urine was measured by gas-liquid chromatography method. The correlation analysis showed that carbon monoxide affects the rate of excretion of ethanol from the body. Among individuals under 40 years of age, there was a correlation between the level of carbon monoxide and the amount of ethanol in the blood. Among older adults this correlation was not established. A direct correlation with the level of this gas in the blood and the level of ethanol in the urine among people under 40 years of age was found. Among older individuals, the opposite was observed –a high level of methemoglobin was responsible for the decreased level of ethanol. There were no correlations between methemoglobin level and age. Comparison of the studied indices did not show any sexual differences in ethanol excretion, but there were age specific features: ethanol excretion under the influence of carbon monoxide among people under 40 years old was more accelerated.Key words:hypoxia, CO intoxication, blood, methemoglobin, kidneys. Монооксид карбону являє собою токсичний газ, який не має кольору,без запаху та здатен спричиняти миттєву гіпоксію шляхом зв’язування з гем-вмісними білками. Через такі властивості він спричиняє найбільшу кількість отруєнь. Цей газ,завдяки своїм властивостям,спричиняє ураження нервової та серцево-судинної системи. Розвиток аноксії пов’язаний із впливом на систему окисного фосфорилювання у мітохондріях та розвиткомоксидативного стресу. В організмі продукується невелика кількість ендогенного монооксиду карбону внаслідок розпаду еритроцитів. Пікомолярні концентрації монооксиду карбону навіть володіють протизапальними, антиапоптичними, цитопротекторними та антипроліферативними властивостями. Нирки є одним із перших органів, який реагує на розвитокгіпоксії, вони відповідають за видалення продуктів метаболізму й токсикантів, зокрема етанолу.Зміни у функціонуванні нирок відображаються на загальному стані організму.Для дослідження отримували зразки крові та сечі від осіб із гострою інтоксикацією. У крові спектрофотометричним методом визначали вміст метгемоглобіну, який утворювався внаслідок вдихання монооксиду карбону та відповідного потрапляння до кровоносної системи. Методом газово-рідинної хроматографії вимірювали концентрацію етанолу у крові та сечі. Розрахунок кореляційних зв’язків показав, що монооксид карбону впливає на швидкість екскреції етанолу. У осіб до 40 років спостерігалася кореляція між показником рівня метгемоглобінута вмістом етанолу у крові. У осіб старшого віку цього зв’язку не встановлено. Виявлено прямий зв’язок із рівнем цього газу у крові та рівнем етанолу в сечі у осіб до 40 років. У осіб старшого віку спостерігалася зворотня реакція–високий рівень метгемоглобінуобумовлював зниження рівня етанолу. Кореляційні зв’язки між вмістом метгемоглобіну та віком не було виявлено. Порівняння досліджуваних показників не виявило статевих відмінностей у екскреції етанолу, проте виявлено вікові особливості: екскреція етанолу в умовах впливу монооксиду карбону в осіб до 40 років була більш пришвидшена.Таким чином, можна стверджувати, що монооксид карбону обумовлює зміни у функціональній активності нирок.Ключові слова:гіпоксія, інтоксикація СО, кров, метгемоглобін, нирки.

This review aim to discuss the important components of Coronavirus Disease (COVID-19) and possible correlations, interactions with oral/periodontal structures. With the beginning of the announcement of the transformation of COVID-19 from an epidemic into a pandemic, it was necessary to realize the injury of several million people infected with this disease and others will become infected soon and its impact on public health as well as the adverse effect of chronic diseases and their causes for the spread of COVID-19. Chronic periodontal diseases are one of the most widespread diseases around the globe and one of their supposed causes is the presence of many microbial plaques, including bacteria and viruses. Presence of coronavirus receptors on the cells of the oral mucosa, and cells of the periodontal pockets, may give a way to adhere the virus and spread inside the body through the periodontium. SARS-CoV-2 virus was found in some saliva samples. A conceivable relevance between periodontitis and COVID-19 has been hypothesized. Defense against COVID-19 in dental clinical consist of three ascending levels. It is advised to utilize a mouth rinse against SARS-CoV-2. At end of this review, oral health providers and periodontists will gain essential knowledge to the successful confrontation against the Coronavirus Disease (COVID-19).

Background: Carbon Monoxide (CO) poisoning is a frequent cause of intoxication. However, CO poisoning incidence is globally underreported, as well as its features, especially in Italy. The aim of this study was to investigate such characteristics of CO intoxication and foster the creation of the Italian Registry of Carbon Monoxide Poisonings. Methods: A data collection tool was developed and organized in five sections: Patient’s characteristics; CO intoxication modality; emergency medical service and emergency department; hyperbaric facility; outcomes. The tool was validated through a retrospective analysis, including CO intoxicated patients treated in 14 Italian hyperbaric facilities between 2015 and 2016. Results: A total of 1383 patients were included. The high completion ratio (85%) of the collection tool suggests its feasibility in practical terms. CO intoxications were mostly accidental (93.64%) and caused by solid fuel (48.59%). There was not a uniform application of hyperbaric oxygen treatment protocols, but most of the patients were adequately treated at least at 2.5 ATA for more than 60 min (44.97%). Conclusion: This analysis provided new information that was previously unavailable in this country. Furthermore, this tool proved to be a valid base for future registry aiming to consolidate the body of knowledge about CO intoxications in Italy.

The most hygienically safe process of recycling polymers is mechanical recycling, which does not cause the destruction of polymers, products of which dangerously affect all components of the environment and man. The purpose of the study is to predict the non-carcinogenic risk to public health from the production of mechanical processing of secondary polymers, depending on the presence or absence of the stage of mechanical activation in the processing process. Materials and methods: sanitary-epidemiological examination; risk assessment of dangerous factors for public health; instrumental assessment methods; statistical processing of results – determination of arithmetic mean values, standard error, quadratic deviation. Results and discussion. It is established that the total indicators of air pollution by polymer dust, nitrogen dioxide and carbon monoxide do not exceed the permissible level of pollution, and the degree of danger of this category of production is assessed as safe. Analysis of the obtained values of hazard coefficients of chemicals for the production of mechanical processing of secondary polymer raw materials without the stage of mechanical activation showed that the risk level for the maximum concentration of polymer dust and nitrogen dioxin at a distance of 25 m is assessed as alarming. The hazard factor for the maximum concentration of carbon monoxide at all distances studied did not exceed the permissible limits. For the production of mechanical processing of secondary polymer raw materials with the stage of mechanical activation, the level of risk for any of the test substances and at all distances studied did not exceed the allowable. Conclusion. Indices of danger of impact on individual organs and systems of the body (respiratory system, central nervous system, cardiovascular system, blood, eyes) of the investigated substances (polymer dust, nitrogen dioxide, carbon monoxide) at a distance of 50 m from the processing of secondary polymer raw materials without stages of mechanical activation are admissible, and for production with a stage of mechanical activation – minimum. It is established that according to the indicators of non-carcinogenic risk, sanitary-protection zone of production facilities for mechanical processing of secondary polymer raw materials without the stage of mechanical activation cannot be less than 50 m, and with the stage of mechanical activation can be reduced to 25 m

The current use of serum retinol concentrations as a measurement of subclinical vitamin A deficiency is unsatisfactory for many reasons. The best technique available for vitamin A status assessment in humans is the measurement of total body pool size. Pool size is measured by the administration of retinol labelled with stable isotopes of carbon or hydrogen that are safe for human subjects, with subsequent measurement of the dilution of the labelled retinol within the body pool. However, the isotope techniques are time-consuming, technically challenging, and relatively expensive. There is also a need to assess different types of tracers and doses, and to establish clear guidelines for the use and interpretation of this method in different populations. Field-friendly improvements are desirable to encourage the application of this technique in developing countries where the need is greatest for monitoring the risk of vitamin A deficiency, the effectiveness of public health interventions, and the potential of hypervitaminosis due to combined supplement and fortification programs. These techniques should be applied to validate other less technical methods of assessing vitamin A deficiency. Another area of public health relevance for this technique is to understand the bioconversion of β-carotene to vitamin A, and its relation to existing vitamin A status, for future dietary diversification programs.

The high prevalence of preventable infectious and chronic diseases in Australian Indigenous populations is a major public health concern. Existing research has rarely examined the role of built and socio-political environmental factors relating to remote Indigenous health and wellbeing. This research identified built and socio-political environmental indicators from publicly available grey literature documents locally-relevant to remote Indigenous communities in the Northern Territory (NT), Australia. Existing planning documents with evidence of community input were used to reduce the response burden on Indigenous communities. A scoping review of community-focused planning documents resulted in the identification of 1120 built and 2215 socio-political environmental indicators. Indicators were systematically classified using an Indigenous indicator classification system (IICS). Applying the IICS yielded indicators prominently featuring the “community infrastructure” domain within the built environment, and the “community capacity” domain within the socio-political environment. This research demonstrates the utility of utilizing existing planning documents and a culturally appropriate systematic classification system to consolidate environmental determinants that influence health and disease occurrence. The findings also support understanding of which features of community-level built and socio-political environments amenable to public health and social policy actions might be targeted to help reduce the prevalence of infectious and chronic diseases in Indigenous communities.

A laboratory-developed test (LDT) is a type of in vitro diagnostic test that is developed and used within a single laboratory. The holistic metabolomic LDT integrating the currently available data on human metabolic pathways, changes in the concentrations of low-molecular-weight compounds in the human blood during diseases and other conditions, and their prevalent location in the body was developed. That is, the LDT uses all of the accumulated metabolic data relevant for disease diagnosis and high-resolution mass spectrometry with data processing by in-house software. In this study, the LDT was applied to diagnose early-stage Parkinson’s disease (PD), which currently lacks available laboratory tests. The use of the LDT for blood plasma samples confirmed its ability for such diagnostics with 73% accuracy. The diagnosis was based on relevant data, such as the detection of overrepresented metabolite sets associated with PD and other neurodegenerative diseases. Additionally, the ability of the LDT to detect normal composition of low-molecular-weight compounds in blood was demonstrated, thus providing a definition of healthy at the molecular level. This LDT approach as a screening tool can be used for the further widespread testing for other diseases, since ‘omics’ tests, to which the metabolomic LDT belongs, cover a variety of them.

Oxidative stress is a result of disruption in the balance between antioxidants and pro-oxidants in which subsequently impacting on redox signaling, causing cell and tissue damages. It leads to a range of medical conditions including inflammation, skin aging, impaired wound healing, chronic diseases and cancers but these conditions can be managed properly with the aid of antioxidants. This review features various studies to provide an overview on how Carica papaya help counteract oxidative stress via various mechanisms of action closely related to its antioxidant properties and eventually improving the management of various oxidative stress-related health conditions. Carica papaya is a topical plant species discovered to contain high amounts of natural antioxidants that can usually be found in their leaves, fruits and seeds. It contains various chemical compounds demonstrate significant antioxidant properties including caffeic acid, myricetin, rutin, quercetin, α-tocopherol, papain, benzyl isothiocyanate (BiTC), and kaempferol. Therefore, it can counteract pro-oxidants via a number of signaling pathways that either promote the expression of antioxidant enzymes or reduce ROS production. These signaling pathways activate the antioxidant defense mechanisms that protect the body against both intrinsic and extrinsic oxidative stress. To conclude, Carica papaya can be incorporated into medications or supplements to help manage the health conditions driven by oxidative stress and further studies are needed to investigate the potential of its chemical components to manage various chronic diseases.
