Molluscicidal Activity

Laboratory and field bioassays have confirmed the specificity of the molluscicidal activity of the Euphorbia splendens var. hislopii latex (crown of Christ) (Euphorbiaceae) over snails of the species Biomphalaria glabrata, B. tenagophila, B. straminea, B. pfeifferi and Bulinus sp. in the control of Schistosoma mansoni. In the present study, the effect of the pH variation on lethal concentration (LC90) over B. tenagophila was evaluated. Bioassays with the aqueous solutions of the latex ranging from 0.4 to 12 µl/l were adjusted for pH of 5.0; 6.0; 7.0 and 8.0, and tested in accordance with methods standardized by World Health Organization. The results obtained indicated that the minor concentration of the latex occurred at pH 6.0 (LC90 = 3.2 µl/l) and the maximum at pH 8.0 (LC90 = 10.3 µl/l). Lethal concentrations adjusted for pH 5.0 and 7.0 were 3.4 µl/l and 4,7µl/l, respectively. From the results it could be concluded that the molluscicidal toxicity was not altered when the concentrations were adjusted for pH 5.0 and 6.0, as we observed that mortality rate was 100% starting at a concentration of 2.0 µl/l, not the same for the concentrations with adjustment for pH 7.0 and 8.0.

The toxic profile of lawsone (2-hydroxy-[1,4]naphthoquinone) and a series of [1,4]naphthoquinone derivatives was evaluated against the brine shrimp Artemia salina and against the mollusk Biomphalaria glabrata, the main transmitting vector of schistosomiasis in Brazil. Of the seventeen compounds tested nine fell below the threshold of 100 µg/mL set for potential molluscicidal activity by the World Health Organization. As a general rule derivatives with non-polar substituents presented the highest molluscicidal activities. These substances showed significant toxicity in A. salina lethality bioassay.

In this study, we investigated the association between the plasma NT-proBNP level at admission and the severity of COVID-19 pneumonia. For this retrospective, single-centre cohort study, we enrolled consecutive patients from February 9 to March 4, 2020, in a COVID-19 ward of Hubei General Hospital (East Branch) in Wuhan, which is a government-assigned centre for COVID-19 treatment. Diagnosis was confirmed by microbiological and radiographic findings following the interim guidance of the World Health Organization (WHO). A total of 91 (92.9%) patients were finally included in this study. The median age of the patients was 61 years (IQR, 47–69), and 39 (43.0%) of them were male. Two cases of death were reported (2.3%). Twenty-three patients (25.3%) had NT-proBNP levels above 300 pg/ml. Higher NT-proBNP levels were associated with worse PSI and CT scores. The natural logarithm of the NT-proBNP level was positively correlated with the PSI and CT scores (PSI score: rS = 0.396, P = 0.001 ; CT score: rS = 0.440, P < 0.001 ). Patients with NT-proBNP ≥300 pg/ml showed a potential risk for higher mortality than patients with NT-proBNP <300 pg/ml (mortality rate, 8.7% vs. 0%; P = 0.062 ). The plasma NT-proBNP level of COVID-19 patients was significantly related to the severity of pneumonia.

Coronavirus also known as COVID 19 or SARS N-CoV2 is a recent virus outbreak and pandemic in nature infecting and spreading among humans all around the earth. Since it’s a communicable disease it’s considered to be most dangerous in terms of spread regardless of its mortality rate. However, World Health Organization (WHO) has given guidelines to overcome the spread of the pandemic and at the same time, all the nations have followed serious actions and procedures by way of social distancing, lockdown, home quarantine etc. to curb the spread and to curtain the virus. The lockdown has stopped human activities and paralysed economic conditions but environmental rejuvenation is taking place at a great speed.

The spread of Corona virus disease 19 (Covid-19) which has been going on since December 2019 has had a very broad impact on all walks of life. Data quoted from the official website of the World Health Organization (WHO), as of September 25, 2020, reported that there were more than 31,026,758 confirmed cases of Covid-19 worldwide, and more than 755,786 people had died with positive Covid-19 ( 1). Meanwhile in Indonesia, as monitored by the Kompas.com website, 137,468 confirmed cases of Covid-19 were reported and more than 6,071 people died. The mortality rate is estimated to be 4.416%, of which most cases involve the elderly (> 80%) (2). Seeing the reality on the ground, by not being disciplined in responding to health protocols to prevent Covid-19 transmission, this number will continue to show an increase.

Abstract Background This study aimed to assess the impact of 15 days before, 15 days during, and 15 days after the lockdown on the trends in the prevalence and mortality in 27 countries during COVID-19 pandemic. Methods Twenty-seven countries were randomly selected from the different continents. The information on the trends in the prevalence and mortality due to COVID-19 pandemic in 27 countries was obtained from World Health Organization and lockdown data were obtained from concerned countries and their ministries. The impact of lockdown for 15 days before, 15 days during, and 15 days after the lockdown on the prevalence and mortality due to the COVID-19 pandemic in 27 countries was analyzed. Results The findings showed that 15 days after the lockdown there was a trend toward a decline, but no significant decline in the mean prevalence and mean mortality rate due to the COVID-19 pandemic compared to 15 days before, and 15 days during the lockdown in 27 countries. The mean growth factor for number of cases was 1.18 and for mortality rate was 1.16. Conclusions The findings indicate that 15 days after the lockdown, daily cases of COVID-19 and the growth factor of the disease showed a declined trend, but there was no significant decline in the prevalence and mortality.

Road deaths phenomenon suggests the development of studies that consider the complex causal relationship between the factors that influence it at the compatible level with the definition of road safety policies. This paper analyzes the influence of 48 road safety performance indicators on the mortality rate of 175 World Health Organization Member States in 2016. Structural equation models were proposed to evaluate the proposition and use of latent variables that represent five major road safety policy areas and the influence on mortality rates. The proposed model structure indicated that management has a strategic role in public policies, having an indirect influence on reducing the mortality rate through safe vehicles, user safety, and safe roads and mobility. The results indicated that policies aimed at encouraging users’ safe behavior were the ones that had the greatest influence in reducing road deaths followed by policies in safer vehicles, road safety management, safer roads and mobility, and post-crash response.

The number of confirmed cases of COVID-affected patients are 1,123,000 and counting while more than 59,000 corroborated mortalities have occurred around the globe, as depicted by the data gathered through Johns Hopkins University. More than 228,000 people have reportedly recovered from COVID-19 till April 4 2020. Italy has the second highest deaths of COVID-19 in the world. There is dire need to evaluate the pattern of COVID-19 in Pakistan and compared with other developed countries. World Health Organization has developed website to provide latest data in form of new reported cases, mortality and recoveries.  In Pakistan, mortality rate was found less than other developed countries and this hypothesis may be wrong that Pakistan neither will nor effected with virus due to climate conditions. The presented study had two objectives. The first was to describe the latest situation if COVID-19 in Pakistan and other developed countries. Second objective was to determine the latest situation about mortility rate in Pakistan and other developed countries. Comparative data was sketched and presented in the form of graph for 5 countries including Pakistan. All the data was obtained form WHO websites and from Pakistan government officials websites. Data was collected from Jan-2020 to 4 April-2020.
