This research aims at evaluating the effectiveness of Delonix regia as a natural coagulant in treating low turbid water. The active ingredient of the coagulant was extracted using Soxhlet Apparatus with Hexane as the solvent. The water sample was obtained from the famous Ala river in Akure, Ondo state. The water from this river is oftentimes used by the residents without treatment because it appears clean to them, this river had a turbidity of 18.4NTU which is above the standard (5NTU) required by the World Health Organization (WHO) for safe usage. After treating with different doses (0.03g/L to 0.4g/L) of the coagulant, an optimum value of 6.12NTU at an optimum dose of 0.03g/L and a turbidity reduction of was obtained 66.74%, alongside an improvement in other water parameters such as Conductivity, dissolved oxygen and total dissolved solids. This result proves the effectiveness of Delonix regia as a natural coagulant in treating low turbid water. However, treatment with Delonix regia is not sufficient to improve the quality of low turbid water to WHO acceptable limits for potable water.

Aus Untersuchungen in der Normalbevölkerung ist bekannt, dass Menschen mit erhöhten Alexithymiewerten eine verminderte Lebensqualität (LQ) aufweisen. Für Patienten mit psychischen Störungen wurde dieser Zusammenhang jedoch kaum untersucht. Ziel dieser Studie war es, den möglichen Zusammenhang zwischen alexithymen Patientenmerkmalen und der LQ bei Patienten mit Angststörungen zu überprüfen. Bei 79 ambulanten Patienten mit Angststörungen wurden alexithyme Charakteristika mit der Toronto Alexithymia Scale (TAS-20), die LQ mit der Kurzversion des World Health Organization Quality of Life Questionnaire 100 (WHOQOL-BREF) erfasst. Darüber hinaus fand eine Erhebung der psychischen Symptombelastung (SCL-90-R) und depressiven Symptomatik (MADRS) statt. Mittels hierarchischer Regressionsanalysen wurde der Zusammenhang zwischen der alexithymen Charakteristika und den unterschiedlichen LQ-Domänen berechnet. Die Patienten zeigten eine im Vergleich zur Normalbevölkerung deutlich verminderte LQ. Als Hauptergebnis fand sich, auch nach Kontrolle von Depression, Ängstlichkeit und Geschlecht, ein signifikanter Zusammenhang zwischen den beiden TAS-20 Subskalen Schwierigkeiten, Gefühle zu identifizieren und zu beschreiben und vor allem der psychischen LQ. Unsere Ergebnisse sprechen dafür, bei der Diagnostik und Therapieplanung von Patienten mit Angststörungen alexithyme Merkmale einzubeziehen. Im Falle von ausgeprägten alexithymen Merkmalen sollten psychotherapeutische Interventionen zur Verbesserung der Schwierigkeiten Gefühle wahrzunehmen und zu kommunizieren in Betracht gezogen werden.

In Rajasthan state the ground waters of some areas like Ramganj-mandi, Morak, Barmer, Jaisalmer, Chittor and Udaipur etc. are susceptible from drinking point of view.To test the quality of groundwater in Chittor district 14, ground water samples were collected from various places and analyzed for pH, E.C., Fluoride and Nitrate parameters by standard methods (A.P.H. A., Washington, USA, 1995). The study revealed that none of the ground waters was found suitable completely from drinking point of view. Some are having electrical conductivity > 1.4 dS/m, some are having pH >8.5, some area having fluoride >1.5 ppm and some are having nitrate>45 ppm. These are the limits of various parameters permitted by various International authorities like Bureau of Indian Standard, Indian Council of Medical Research,world health Organization etc. for drinking waters. So, it is recommended to the residents of above areas to use water for drinking purpose only after reverse osmosis or adopting suitable method of removing excess of Fluoride and Nitrate for drinking water to avoid unwanted pathogenic diseases harmful for human health.

OBJECTIVE: To evaluate the perception of Quality of Life (QL) in Brazilian patients with narcolepsy. METHOD: 40 adult patients aged between 20 and 72 years (mean=41.55; SD=14.50); (28 F; 12M), with the diagnosis of chronic narcolepsy were followed up at the outpatient clinic (Patient Group). The Control Group was composed of 40 adults. The instrument utilized was the World Health Organization Quality of Life (WHOQOL-BREF). RESULTS: The two groups were homogeneous and no difference was found with regards to age, sex, and demographic characteristics. The perception of QL in physical, psychological and social domains showed lower scores in those patients with narcolepsy than in the control group (p<0.05). Concerning physical domain, all the aspects evaluated were significantly impaired, in patient group, including sleep satisfaction (p<0.001); energy for daily activities (p=0.039); capacity to perform activities (p=0.001); and capacity to work (p=0.001). CONCLUSION: The perception of QL showed severe impairment in patients with narcolepsy for physical, psychological and social domains.

Abstract Objectives This systematic and meta-analysis review was conducted to determine the status of Iranian children and adolescents’ physical activity. Content All the related articles which were published in the major databases, including Pubmed, Scopus, Web of Science, Embase, Magiran, SID from the beginning of 2010 to the end of 2019, were reviewed by researchers. The Newcastle-Ottawa scale was also used to evaluate the quality of articles. Moreover, I 2 index and chi-square were used to assess the heterogeneity between the results. Summary 490 articles were found as a result of the search in the selected international and local databases, where finally, 10 articles were included into the meta-analysis after the elimination of the duplicated articles and applying inclusion and exclusion criteria. The results indicated that 29.5% of the girls were considered active according to WHO criteria (16.1–42.8: 95% CI) and also 20.5% of the boys (7.3–33.7: 95% CI). Outlook Overall, this study’s findings showed that a large percentage of Iranian children and adolescents do not achieve the level of physical activity recommended by the World Health Organization. This can lead to undesirable consequences for this group of population that is considered as the human capital of any country; consequently, it seems necessary to take basic measures at the micro and macro levels in order to reduce such problems in the society.

Abstract Background Joint contractures, which affect activity, participation, and quality of life, are common complications of neurological conditions among elderly residents in long-term care facilities. This study examined the reliability and validity of the Chinese version of the PaArticular Scales in a population with joint contractures. Methods A cross-sectional study design was used. The sample included elderly residents older than 64 years with joint contractures in an important joint who had lived at one of 12 long-term care facilities in Taiwan for more than 6 months (N = 243). The Chinese version of the PaArticular Scales for joint contractures was generated from the English version through five stages: translation, review, back-translation, review by a panel of specialists, and a pretest. Test-retest reliability, internal consistency reliability, construct validity, and criterion validity were evaluated, and the results were compared with those for the World Health Organization Quality of Life scale and the World Health Organization Disability Assessment Schedule. Results The Chinese version of the PaArticular Scales had excellent reliability, with a Cronbach α coefficient of 0.975 (mean score, 28.98; standard deviation, 17.34). An exploratory factor analysis showed three factors and one factor with an eigenvalue > 1 that explained 75.176 and 62.83 % of the total variance in the Activity subscale and Participation subscale, respectively. The subscale-to-total scale correlation analysis showed Pearson correlation coefficients of 0.881 for the Activity subscale and 0.843 for the Participation subscale. Pearson’s product-moment correlation revealed that the correlation coefficient (r) between the Chinese version of the PaArticular Scales and the World Health Organization Disability Assessment Schedule was 0.770, whereas that for the World Health Organization Quality of Life scale was − 0.553; these values were interpreted as large coefficients. Conclusions The underlying theoretical model of the Chinese version of the PaArticular Scales functions well in Taiwan and has acceptable levels of reliability and validity. However, the Chinese version must be further tested for applicability and generalizability in future studies, preferably with a larger sample and in different clinical domains.

SummaryWe are still confronted by numerous different nosographic models and problems concerning the objective evaluation of patients progress during treatment. It is interesting to consider the consequences of this situation in psychiatry which still involves a relative diversity of practical methods used in clinical trials. The recommendations of the USA Food and Drug Administration, on the one hand, constitute a highly structured and precise reference. The World Health Organization, on the other hand, promulgates general recommendations resulting from a compromise designed to satisfy the greatest number of clinicians.Despite the apparently diverse principles and the different practical methods they propose, both those sets of recommendations have been useful in inspiring clinicians to reflect upon these different methodological approaches. The qualities of the inclusion criteria used in the study of patients and the sensitivity of the different measuring instruments have allowed psychotropic drug users as well as producers to recognize the need for a certain rigour in clinical trials.The FDA and WHO guidelines have certainly improved the quality of clinical trials in psychopharmacology. However, they also represent a source of resistance to innovation.A series of consensus meetings to first reconcile US and European points of view and later to include new techniques in the recognized sets of methods would therefore be helpful.

Abstract Background The global coronavirus disease 2019 (COVID-19) was announced as pandemic by the World Health Organization (WHO). With the increased number of infected and dead victims daily all over the world, it becomes necessary to stop or overcome its rapid spread. Main body Although the production of vaccine or even specified effective anti-virus may take about six months to a year, intravenous immunoglobulin (IVIg) may be clinically used as a safe treatment to save and improve the quality of life of patients with a variety of immunodeficiency diseases such as lymphocytopenia, which is a common clinical feature in COVID-19. Conclusion Through the current review, it was concluded that this passive immunization may promote the immunity to better fight against the virus, so the survival of the patients could be kept longer. The efficacy of immunotherapy with IVIg would be greater if the immune IgG antibodies were collected from convalescent plasma therapy.
