Introduction: Although, used of molluscicides to control the intermediate host of schistosomes is the best method of choice to control the spread of the snail fever among the people, synthetic molluscicides widely used are cost effective, not available and toxic to the aquatic lives and people that are completely or partially dependents on rivers or lakes water for their everyday supplement. Aim: this research was aimed at investigation and comparison for the molluscicidal efficacy for S. occidentalis and M. oleifera leaves extracts against B. globosus (intermediate host of Schistosoma haematobium). Methodology: Each of the plant was grinded into powder and purified through column using different solvents, B. globosus snails were collected from Shagari and Goronyo dams; we identified the animal using chart initially, later on the animals were confirmed as B. globosus by malacologist from Ahmadu Bello University Zaria, Nigeria; the Molluscicidal efficacy of the plants was tested against B. globosus and compared according to world health organization guidelines; mortality was calculated using Abbort’s formula and analysis of variance (ANOVA) was used to determine if there is significant different between the mean mortality at P<0.05; qualitative Phytochemical analysis was conducted to determine the chemicals presence in each plant and their combination. Results: Present study reviled that fractions of the leaves combination showed significantly higher mortality of B. globosus in the present study followed by Fractions of S. occidentalis then that of M. oleifera. For the plants combination, extracts purified using methanol are highly toxic followed by fractions purified using hexane, then ethyl acetate fractions and least Molluscicidal potential was recorded in the fractions obtained using ethanol. S. occidentalis fractions of hexane were highly toxic followed by fractions of methanol, then fractions of ethyl acetate and least mortality was recorded from the fractions of ethanol. Similarly, for the M. oleifera, it was observed that, fractions of Methanol were highly toxic followed by hexane fractions then ethanol fractions and least mortality was observed in the fractions of ethyl acetate. Conclusion: Column purified fractions for the combination for two plants leaves were highly potent for the control of B. globosus followed by S. occidentalis then M. oleifera.

Synthetic molluscicides widely used for the control of urinary schistosomiasis are expensive, toxic to non-target organisms, not available and may have deleterious long-term effects in the environment. The aim of this research is to compare the efficacy of column purified fractions of Allium cepa and Allium sativum against Bulinus globosus specimens (intermediate host of urinary schistosomiasis) under laboratory conditions as an increment for the cheaper, non-toxic, available way of controlling urinary schistosomiasis. Extracts were obtained using cold maceration method with methanol as a polar solvent; column purification was achieved using silica gel (stationary phase) while ethyl acetate and n-hexane (mobile phase); thirteen fractions were collected from each plant and each fraction contained 10ml of the eluent; the fractions were left open for 48 hours for evaporation of the solvents. Experiments were performed according to the methodology described by the World Health Organization for molluscicidal activity tests; each treatment was replicated three times; mortality was recorded after each 24 hours up to 96 hours. The results showed that; A. sativum was more effective against B. globosus as compared with A. cepa with statistical significant difference (P<0.05) and LC50 were 15.60mg/l and 19.37mg/l for the efficacy of A. cepa and A. sativum respectively. It was concluded that, although, A. cepa purified fractions are more effective than A. sativum against B. globosus, both of the plants species may be helpful in snail control at acceptable doses since the plant extracts caused mortality of the snail.

The Impact

Introduction: The noise levels in the ICUs exceed the levels suggested by the World Health Organization, because of the noises caused by devices and human noises. The aim of this study is to retrospectively examine the changes in audiometry results of nurses working in ICU.   Methods: The audiometry results of nurses who worked for an uninterrupted period of 1 year in ICU in the last 3 years were examined retrospectively based on the results recorded at the time of employment and in the last year of working. Age, gender, years of work, assessments of hearing level and high frequency hearing losses were recorded. The normal level of hearing was accepted as 0-25dB.   Results: Totally 10 male (25.6%), 29 female (74.4%) were included in the study. The mean age was 26.97 ± 4.69 years and the mean time of employment was 1.82 ± 0.91 years. The mean values of pure tone levels during the years of working were within the normal limits but a significant increase was observed. Two subjects (5.1 %) were confirmed to have high frequency hearing loss.    Discussion and Conclusion: We believe that safety of the staff might be improved by reducing the level of noise in the ICUs and identifying the people at risk with yearly audiometry follow-ups.

A novel, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), causes severe acute respiratory syndrome and spread globally from Wuhan, China. In March 2020 the World Health Organization declared the SARS-Cov-2 virus as a COVID- 19, a global pandemic. This pandemic happened to be followed by some restrictions, and specially lockdown playing the leading role for the people to get disassociated with their personal and social schedules. And now the food is the most necessary thing to take care of. It seems the new challenge for the individual is self-isolation to maintain themselves on the health basis and fight against the pandemic situation by boosting their immunity. Food organised by proper diet may maintain the physical and mental health of the individual. Ayurveda aims to promote and preserve the health, strength and the longevity of the healthy person and to cure the disease by properly channelling with and without Ahara. In Ayurveda, diet (Ahara) is considered as one of the critical pillars of life, and Langhana plays an important role too. This article will review the relevance of dietetic approach described in Ayurveda with and without food (Asthavidhi visheshaytana & Lanhgan) during COVID-19 like a pandemic.

Background: The World Health Organization included snakebite envenomation among Neglected Tropical Diseases in 2017. The importance of natural products from plants is enormous, given that most prescribed drugs originate from plants. Among this is Mucuna pruriens and Mimosa pudica, with many registered patents asserting their health benefits. Objective: This study investigated the in vitro neutralizing effects of Mucuna pruriens seed and Mimosa pudica root extracts on venoms of Naja nigricollis and Bitis arietans. Methods: In mice, the LD50 and phytochemical analysis of M. pruriens and M. pudica plant extracts were carried out prior to the evaluation of their haemolytic and fibrinolytic effect. Their effects on the activities of phospholipase A2 (PLA2) were also assessed. Results: At a concentration of 50 mg/ml, both plant extracts were found to neutralize the fibrinolytic activity of N. nigricollis, but 400 mg/ml was required to neutralize the fibrinolytic activity of B. arietans. In haemolytic studies, 50 mg/ml concentration of M. pruriens extract suppressed haemolysis caused by N. nigricollis venom by 70% but at the same concentration, M. pudica extract reduced haemolysis by 49.4%. M. pruriens, at 50 mg/ml concentration, only inhibited phospholipase A2 activity by 7.7% but higher concentrations up to 400mg/ml had no effect against the venom of N. nigricollis; at 200 mg/ml. M. pudica extract inhibited PLA2 activity by 23%. Conclusion: The results suggest that M. pruriens and M. pudica may be considered as promising antivenom agents for people living in a snake-bite prone environment.

In 2012, the World Health Organization (WHO) established the Global Vaccine Action Plan with the objective to promote essential vaccinations in all countries and achieve at least 90% vaccination coverage for all routine vaccines by 2020. The study assessed the mean percentages of vaccination coverage in 2019 for 13 routine vaccines, vaccination coverage variation from 2015 to 2019, and herd immunity levels against measles and pertussis in 2019 in countries and regions of WHO. In 2019, the mean percentages of vaccination coverage were lower than 90% for 10 (78.9%) routine vaccines. The mean percentages of vaccination coverage also decreased from 2015 to 2019 for six (46.2%) routine vaccines. The prevalence of individuals with vaccine-induced measles immunity in the target measles vaccination population was 88.1%, and the prevalence of individuals with vaccine-induced pertussis immunity in the target pertussis vaccination population was 81.1%. Herd immunity against measles viruses with Ro = 18 was established in 63 (32.5%) countries but not established in any region. Herd immunity against pertussis agents was not established in any country and in any region of WHO. National immunization programs must be improved to achieve ≥90% vaccination coverage in all countries and regions. Likewise, it is necessary to achieve ≥95% vaccination coverage with two doses of measles vaccines and three doses of pertussis vaccines in all countries and regions.

Cover Up

Background: The World Health Organization (WHO) has estimated drowning as the leading cause of unintentional death in the world, with 372,000 deaths reported annually. Not all drowning are unintentional; some could be disguised to cover up an act of heinous criminality. This study was aimed at using some vitreous renal function biochemical parameters as a discriminant of postmortem fresh water drowning. Twelve albino rabbits constituted the sample size as validated by Mead’s formula. The study was divided into three groups; the control, postmortem-drowned and truly drowned as mimicked using an artificial fresh water pond. Vitreous humours were extracted using Coe method. The vitreous renal chemistries were analysed using diacetyl monoxime, Jaffe’s test, uricase and ion-selective electrode (ISE) methods respectively. Result: The mean of vitreous creatinine, urea, uric acid, Na+, K+, Cl−, Ca2+, glucose and CO2 of the control, postmortem-drowned and truly drowned groups were compared using One-way Anova (post-hoc-LSD) with the aid of SPSS Inc., Chicago, IL, USA; Version 18–21 package. The findings revealed a significant increase in concentrations of vitreous creatinine, glucose, Ca2+ and K+ of the drowned death group, whereas vitreous concentrations of CO2 and urea significantly decreased when compared to the controls and/or postmortem-drowned death. Conclusion: The study has shown that some of the studied vitreous biochemical parameters could be used as an ancillary tool in discriminating death due to fresh water drowning from that of disguised or postmortem-drowned death.

ABSTRACTIt is now World Health Organization (WHO) policy that drug concentrations on day 7 be measured as part of routine assessment in antimalarial drug efficacy trials. The rationale is that this single pharmacological measure serves as a simple and practical predictor of treatment outcome for antimalarial drugs with long half-lives. Herein we review theoretical data and field studies and conclude that the day 7 drug concentration (d7c) actually appears to be a poor predictor of therapeutic outcome. This poor predictive capability combined with the fact that many routine antimalarial trials will have few or no failures means that there appears to be little justification for this WHO recommendation. Pharmacological studies have a huge potential to improve antimalarial dosing, and we propose study designs that use more-focused, sophisticated, and cost-effective ways of generating these data than the mass collection of single d7c concentrations.

The purpose of this study was to evaluate the caries experience among 6-12-year-old indigenous (Naporunas) and non-indigenous (recent settlers of mixed ethnic origin) schoolchildren, living in the Amazon basin of Ecuador. Cross-sectional data were obtained from 1,449 clinical exams according to the World Health Organization criteria. Nine (7.6%) indigenous and 3 (4.5%) non-indigenous children had no caries experience in their primary dentition at the age of 6. The mean dmft value (SD) among indigenous and non-indigenous children aged 6 was 6.40 (3.36) and 8.36 (3.93), respectively. Sixty-four (54.2%) indigenous and 29 (43.3%) non-indigenous children had no caries experience in their permanent first molars at the age of 6. Only 7 (6.26%) indigenous and 2 (2.60%) non-indigenous children were caries-free at the age of 12. The mean DMFT values (SD) for 12-year-olds were 4.47 (2.85) among indigenous and 5.25 (2.89) among non-indigenous children. Fillings were almost non existent. Caries rates were high among both groups, with untreated carious lesions predominating in all ages. The data of indigenous children suggest adoption of a non-traditional diet. An appropriate oral health response based primarily on prevention and health promotion is needed.

The Impact

The Safe System (SS) approach to road safety emphasizes safety-by-design through ensuring safe vehicles, road networks, and road users. With a strong motivation from the World Health Organization (WHO), this approach is increasingly adopted worldwide. Considerations in SS, however, are made for the medium-to-long term. Our interest in this work is to complement the approach with a short-to-medium term dynamic assessment of road safety. Toward this end, we introduce a novel, cost-effective Internet of Things (IoT) architecture that facilitates the realization of a robust and dynamic computational core in assessing the safety of a road network and its elements. In doing so, we introduce a new, meaningful, and scalable metric for assessing road safety. We also showcase the use of machine learning in the design of the metric computation core through a novel application of Hidden Markov Models (HMMs). Finally, the impact of the proposed architecture is demonstrated through an application to safety-based route planning.
