Abstract. The inherent havoc caused by scarcity of potable water and transmission of water-borne diseases in some parts of Nigeria have created a public health concern. This study seeks to investigate water purification of four different water samples (namely: water from flowing river; freshly dug well or groundwater; rainwater from the rooftop; and heavily polluted dirty water) consumed by the people in the local community using solar desalination method. A single basin solar still was constructed and experimental studies were carried out to determine the influence of solar insolation and temperature variations on the yield of the distillate. The quality of the distillate was tested by measuring the total dissolved solid (TDS) and electrical conductivity. These were compared to World Health Organization (WHO) standard for drinkable water. These parameters were measured for each water sample before and after desalination to determine the efficiency of the solar still. Results showed a wide gap between the values of TDS and EC before and after desalination of the water samples. The values obtained were in accordance with the requirement of World Health Organization for quality drinkable water. The water becomes clear and less turbid after desalination.

Abstract. The enormous problems caused by the scarcity of potable water and the transmission of waterborne diseases such as cholera, dracunculiasis, hepatitis, typhoid and filariasis in some parts of Nigeria have created a public health concern. Every day thousands of lives are lost due to contact with waterborne diseases. The insufficient medical resources available in developing countries are deployed towards the treatment of waterborne diseases that can easily be avoided if potable water can be made available. This study seeks to investigate the purification of four different water samples (namely water from flowing rivers, freshly dug well or groundwater, rainwater from the rooftops and heavily polluted dirty water) consumed by the people in the local community using a solar desalination method. A single basin solar still was constructed, and experimental studies were carried out to determine the influence of solar insolation and temperature variations on the yield of the distillate for both the passive and active solar stills tested. The quality of the distillate was tested by measuring the total dissolved solid (TDS) and electrical conductivity (EC) and later comparing it to the World Health Organization (WHO) standard for drinkable water. The values obtained after desalination fall within the acceptable/tolerable range for TDS and EC, in accordance with the WHO standard for drinkable water. This analysis provides an indigenous distillation method to enhance the production of drinkable water at a low cost.

Pretendeu-se mostrar que o herbicida Tebuthiuron, selecionado entre outros usados na cultura de cana-de-açúcar, oferece risco de contaminação para a água subterrânea em função de suas características físico-químicas, principalmente, quando aplicado em áreas de recarga direta de aqüíferos consideradas de alta vulnerabilidade natural. Assim, efetuou-se monitoramento do referido herbicida no período compreendido entre 1995 e 1999, coletando amostras de água de poço semi-artesiano, com 53 metros de profundidade, localizado na microbacia do Córrego Espraiado, município de Ribeirão Preto/SP, Brasil, no qual tem sido freqüente o uso do produto em questão. Para efeito de testemunha da amostra de água foi considerado um poço semi-artesiano de profundidade semelhante, localizado cerca de três quilômetros de distância do poço objeto de monitoramento. Os resultados obtidos mostraram que o Tebuthiuron está presente em todas as amostras analisadas, embora em concentrações abaixo do nível crítico para padrão de potabilidade, conforme os limites mais restritivos estabelecidos pela Organização Mundial de Saúde (para os pesticidas em uso é de 0,1 µg/L por pesticida e de 0,5 µg/L para pesticidas totais). Mesmo com os baixos valores de concentração encontrados fica evidente que o Tebuthiuron está atingindo a água subterrânea podendo aumentar sua concentração pela existência de condições ambientais favoráveis à preservação da molécula em profundidade (tais como baixa temperatura, baixa atividade biológica e ausência de luz). Caso o nível crítico seja atingido, o risco de contaminação poderia ser minimizado por meio da substituição do Tebuthiuron por outro herbicida com menor mobilidade no perfil do solo. OCCURRENCE OF THE HERBICIDE TEBUTHIURON IN GROUNDWATER OF ESPRAIADO CATCHMENT RIBEIRAO PRETO - SP (BRASIL) Abstract The herbicide Tebuthiuron, selected among others utilized in sugar-cane crop, shows groundwater contamination risk due to its physicochemical properties, mainly, when applied in direct recharge areas of aquifers considered of high natural vulnerability. In this context, the monitoring of this herbicide in the period of 1995 through 1999 was realized, by collecting water samples of aquifers 53 m depht, located in Espraiado catchment, Ribeirao Preto/SP (Brazil) in which the product has been extensively used. For blank assays it was utilized water samples collected similarly 3 Km away from the monitoring area. The results obtained showed that Tebuthiuron is present in all analyzed samples. Although in lower concentrations of the critical level for drinkable water, following the restrictive limits established by World Health Organization (for pesticides in use is 0,1 µg/L by pesticide and of 0,5 µg/L for total pesticides). Even if the low concentration values found it is evident that the Tebuthiuron affects the groundwater, and could enhance its concentration by favorable ambiental conditions for molecule preservation in deep water (such as low temperature, low biological activity and absence of light). The present scenary reflects contamination risk in case of reaching the critical level, which could only be minimized by the substitution of Thebuthiuron for other herbicide with lower soil mobility.

Novel corona virus (COVID-19) is an infectious condition, which can be spread directly or indirectly from one person to another and causes respiratory illnesses, range from common cold to acute respiratory syndrome. The first cases of this virus were found in Wuhan, China. According to the World Health Organization, COVID-19 is serious health concern and has higher risk for severe illness and spreading rapidly all over the world.This novel coronavirus was named Coronavirus Disease 2019 (COVID-19) by WHO in February 2020. The World Health Organization (WHO) has declared the coronavirus disease 2019 a pandemic, in the year2020 March. A global coordinated effort is needed to stop the further spread of the virus. Among all cases about 92% of the confirmed cases were recorded from China. Initial reports suggest that death rate ranges from 1% to 2% which varies in the study and country. The most of the death have occurred in patients over 50 years of age followed by young children. For the confirmed cases which included both laboratory and clinically diagnosed till now there is no specific antiviral treatment recommended but there is vaccine currently available. Once the virus develops in people, corona viruses can be spread from person to person through respiratory droplets. The viral material hangs out in these droplets and can be breathed into the respiratory tract, where the virus can then lead to an infection. Repercussions of Covid -19 on individuals, families and on front line warriors are countless1.

Abstract Funding Acknowledgements Type of funding sources: None. Background Sudden cardiac death is one of the main issues worldwide, with more than 700.000 deaths annually. It is strongly believed that the implementation of "Kids Save Lives" project in schools can change this situation. The World Health Organization endorsed the ‘Kids Save Lives’ project in 2015 in order to reduce mortality. The first chain of survival concerns the recognition of cardiac arrest with chin lift and head tilt manoeuvre of the victim and the feel- look- listen approach. Purpose Τo evaluate the level of theoretical knowledge, as far the recognition of cardiac arrest is concerned in Greek secondary school students before and after the "Kids Save Lives" program. Material – Method: Data collection took place on the academic periods of 2017-2018 and 2018-2019 and was performed in secondary schools of Thessaly’s region. A total of 4922 students (51,9% female, mean age 14.2 years) participated on the "Kids save Lives" program according to the European Resuscitation Council (ERC) and World Health Organization (WHO) statement. A 12-point questionnaire was answered by the students before and after the "kid saves lives" program, while practical skills were evaluated on manikins by experienced ERC Basic Life Support (BLS) Instructors. The knowledge of the recognition of cardiac arrest is investigated in this subgroup analysis Results The training improves significantly the theoretical knowledge regarding the recognition of cardiac arrest, with the percentage of correct answers being 58,3% and 96,1%,before and after the course respectively (p < 0.001). In the practical part of the program, almost all of the participants (98.9%) could recognize the correct position near the victim and 91% perform chin lift manoeuvre and recognize cardiac arrest. Conclusions The overall results reveal that the "Kids Save Lives" program can play a important role in improving the theoretical knowledge and  the practical skills of Greek students towards towards the recognition of cardiac arrest and indicate the necessity of implementation in a greater scale nationwide.

Abstract Funding Acknowledgements Type of funding sources: None. Background Sudden cardiac death is one of the main issues worldwide, with more than 700.000 deaths annually. It is strongly believed that the implementation of "Kids Save Lives" project in schools can change this situation. The Kids Save Lives initiative, endorsed by the World Health Organization in 2015, is teaching school children worldwide about the importance of CPR and how to perform it. In Greece this project is a suggestion of Ministry of Education to schools. Purpose Τo evaluate the level of theoretical knowledge, willingness to perform Cardiopulmonary resuscitation (CPR) and active skills of Greek secondary school students on the subject of Basic life Support before and after a "Kids Save Lives" program. Material – Method: Data collection took place on the academic periods of 2017-2018 and 2018-2019 and was performed in secondary schools of Thessaly’s region. A total of 5092 students (51,9% female, mean age 14.2 years) participated on the "Kids save Lives" program according to the European Resuscitation Council (ERC) and World Health Organization (WHO) statement. A 12 point questionnaire was answered by the students before and after completing the "kid saves lives" program, while practical skills were evaluated on manikins by experienced ERC Basic Life Support (BLS) Instructors. Results The training improves significantly the theoretical knowledge regarding Cardiopulmonary resuscitation (CPR), with the percentage of correct answers being 48,4% and 82,8%,before and after the course respectively (p < 0.001). The participants willingness to perform bystander CPR significantly increased after the completion of the course (93,7% before to 97,4% after, p < 0.001). Almost all of the participants (98.9%) could recognize the correct position near the victim and 91% performed chin lift maneuver and recognized cardiac arrest. More than 90% of the students performed chest compressions with the correct rate and placing their hands on the center of the chest (90,1% and 93.4%, respectively), whereas only 76.1% of the participants achieved the desired compression depth of 5 to 6 cm. Conclusions The overall results strongly recommend that the "Kids Save Lives" program can boost prospects for bystander CPR and indicate the necessity of implementation in a greater scale nationwide.

It is strongly believed that the implementation of "Kids Save Lives" project in schools can change this situation. The World Health Organization endorsed the ‘Kids Save Lives’ project in 2015 in order to reduce mortality. On the other hand the use of automatic external defibrillators (AED) is associated with higher survival rate after a cardiac arrest. Purpose Τo evaluate the level and the improvement of theoretical knowledge of secondary school students on the subject of AEDs  before and after the "Kids Save Lives" respectively. Material – Method: Data collection took place on the academic periods of 2017-2018 and 2018-2019 and was performed in secondary schools. A total of 5562 students participated on the "Kids save Lives" program according to the European Resuscitation Council (ERC) and World Health Organization (WHO) statement. A 12 point questionnaire was answered by the students before and after the "kids saves lives" program. Among other questions, there was one which investigate the knowledge of students in the usage of AEDs and another one asked students to refer a place, where somebody can find an AED. Results The training improves significantly the theoretical knowledge regarding the usage of AEDs, with the percentage of correct answers being 49 % and 85,9%, before and after the  course respectively (p < 0.001).  Moreover, only 19,8% of the students knew a place, where somebody can find an AED before  the course and 77,2% after the course (p < 0,001) Conclusions The overall results strongly depict the benefits of "Kids Save Lives" program by improving the theoretical knowledge on the subject of AEDs. Further research is needed to identify the times a student must follow the program to maximize its effectiveness and more action must take place in order to make students familiar with AEDs.

Abstract Introduction Nasopharyngeal carcinoma (NPC) is the most common malignancy in the field of otorhinolaryngology, and chronic pain is identical with this malignancy. Pain therapy according to World Health Organization (WHO) recommendations is WHO 3-step analgesic ladder. Pain is subjective and related to the function of beta-endorphin hormone. Objective Analyzing the relationship between the degree of pain and plasma endorphin levels in stage III–IV NPC patients before and after the administration of WHO 3-step analgesic ladder. Materials and Methods The study design used pretest and posttest without control design. Participants were given WHO 3-step analgesic ladder therapy for 3 days. The participants then rated the pain scale using the visual analog scale (VAS) and plasma beta-endorphin levels in venous blood. The statistical test used the dependent t-test, Wilcoxon test, and Spearman test with p < 0.05, confidence interval: 95%. Results There were 14 stage-III NPC patients with moderate pain (78.57%) and 31 stage-IV NPC participants had moderate pain (83.87%; p = 0.071). The VAS value in the moderate pain group before and after therapy was 82.22 and 66.67%, respectively (p < 0.001). The values of plasma beta-endorphin levels before and after therapy were 74.89 ± 69.12 and 72.49 ± 75.53 pg/mL, respectively (p = 0.647). Plasma beta-endorphin levels were −19.20 ± 37.72 pg/mL (mild pain), −4.76 ± 35.30 pg/mL (moderate pain), and −21.67 ± 6.27 pg/mL (severe pain; p = 0.717). Conclusion Pain levels in advanced NPC patients have decreased after the therapy, but plasma beta-endorphin levels have no significant difference.
