EVALUATION OF ANTHELMINTIC ACTIVITY OF PRUNUS PERSICA (L.)

Objective: Prunus persica leaves are used as anthelmintic, insecticidal, sedative, diuretic, demulcent, expectorant and vermicidal ethnopharmacologically. Objective of present study was evaluation of anthelmintic activity of different extracts of Prunus persica leaves.Methods: Pheretima posthuma (annelids) and Ascaridia galli (nematods) were used to perform experiments for anthelmintic activity. Piperazine citrate was used as standard. Time required for paralysis and death (lethal time) of worms were noted for each sample of P. persica extracts and standard.Results: The results demonstrated that treatment with Prunus persica significantly (P<0.05-P<0.01) with dose-dependently paralyzed and killed the both A. galli and earthworms. Ethanol and ethyl acetate extracts have showed comparable anthelmintic activity at the highest concentration (60 mg/ml) to the well known anthelmintic agent Piperazine citrate against A. galli.Conclusion: The ethanolic & ethyl acetate extracts exhibited maximum potency i.e. shortest paralysis and lethal times. The potency was not more than the reference drug, piperazine citrate but comparable to it at 60 mg/ml concentrations in both test worms.Keywords: Prunus.

General weighted extropy of minimum and maximum ranked set sampling with unequal samples

In industrial, environmental, and ecological investigations, ranked set sampling is a sample method that enables the experimenter to use the whole range of population values. The ranked set sampling process can be modified in two extremely helpful ways: maximum ranked set sampling with unequal samples and minimum ranked set sampling with unequal samples. They permit an increase in set size without too many ranking errors being introduced. In this paper, we are defining general weighted extropy (GWJ) of minimum and maximum ranked set samples when samples are of unequal size (minRSSU and maxRSSU, respectively). Stochastic comparison and monotone properties have been studied under different situations. Additionally, we compare the extropy of these two sampling data with that of ranked set sampling data and simple random sampling data. Finally, Bounds of GWJ of minRSSU and maxRSSU have been obtained.Comment: 16 page

On weighted cumulative residual extropy and weighted negative cumulative extropy

In this paper, we define general weighted cumulative residual extropy (GWCRJ) and general weighted negative cumulative extropy (GWNCJ). We obtain its simple estimators for complete and right censored data. We obtain some results on GWCREJ and GWNCJ. We establish its connection to reliability theory and coherent systems. We also propose empirical estimators of weighted negative cumulative extropy (WNCJ)

Seroprevalence of hepatitis B virus surface antigen among pregnant females attending antenatal clinic at a tertiary care hospital in North India

Background: Hepatitis B infection is one of the most common public health problems worldwide. Hepatitis B virus Surface Antigen (HBsAg) positive mothers may transmit the virus vertically to neonates transplacentally during pregnancy, perinatally during delivery or postnatally through breast milk. Such neonates being carriers of virus are at a very high risk of developing chronic liver diseases at a younger age and also, they act as reservoirs of infection in the community. Objective of the study is to evaluate the seroprevalence of HBsAg in pregnant females attending Antenatal Clinic.Methods: A hospital based cross-sectional study was done from January to June 2019. A total of 840 pregnant females were included in the study who attended Antenatal Clinic for routine checkup whose blood samples were sent to Microbiology Laboratory for screening of HBsAg by Enzyme Linked Immunosorbent Assay (ELISA).Results: Out of 840 pregnant females included in the study, 8 were reactive to HBsAg, hence, prevalence was found to be 0.95%. The seroprevalence of HBsAg was found to be more (1.40%) in 26-35 year females. Maximum seropositivity was seen in females from urban areas (1.0%), those attending OPD of ANC (1.03%) and those who belonged to lower socio-economic class (1.02%).Conclusions: Routine free screening for HBV infection should be offered to all antenatal females to reduce the risk of vertical transmission to the neonates born to infected mothers, thereby, preventing them from becoming carriers and developing chronic hepatitis and hepatocellular carcinoma later in life

Assessing speech at three years of age in the cleft palate population: A scoping review of assessment practices

Background. There is no consensus in the UK regarding the types of speech samples or parameters of speech that should be assessed at 3 years of age in children with cleft palate ± cleft lip (CP±L), despite cleft units routinely assessing speech at this age. The standardization of assessment practices would facilitate comparisons of outcomes across UK cleft units; earlier identification of speech impairments—which could support more timely treatments; and more reliable recording of therapy impacts and surgical interventions. Aims. To explore assessment practices used to assess speech in 3‐year‐old children with CP±L, including speech parameters, methods of assessment and the nature of the speech sample used. Methods & Procedures. A broad examination of the literature was undertaken through the use of a scoping review conducted in accordance with Joanna Briggs Institute guidelines. Search terms were generated from a preliminary search and then used in the main search (Medline, CINAHL, Embase, AMED and PsycINFO). Main Contribution. A combination of approaches (medical, linguistic, developmental and functional) is required to assess CP±L speech at age 3. A developmental approach is recommended at this age, considering the complexity of speech profiles at age 3, in which typically developing speech processes may occur alongside cleft speech characteristics. A combined measure for both nasal emission and turbulence, and an overall measure for velopharyngeal function for speech, show potential for assessment at this age. Categorical ordinal scales are frequently used; the use of continuous scales has yet to be fully explored at age 3. Although single‐word assessments, including a subset of words developed for cross‐linguistic comparisons, are frequently used, more than one type of speech sample may be needed to assess speech at this age validly. The lack of consensus regarding speech samples highlights a need for further research into the types of speech samples 3‐year‐olds can complete; the impact of incomplete speech samples on outcome measures (particularly relevant at this age when children may be less able to complete a full sample); the impact of different speech samples on the validity of assessments; and the reliability of listener judgements. Conclusions & Implications. Whilst a medical model and linguistic approaches are often central in assessments of age‐3 cleft speech, this review highlights the importance of developmental and functional approaches to assessment. Cross‐linguistic single‐word assessments show potential, and would facilitate the comparison of UK speech outcomes with other countries. Further research should explore the impact of different speech samples and rating scales on assessment validity and listener reliability

Post Traumatic Glioma: An association questioned

Post traumatic glioma has been a matter of debate. Few reports favor its occurrence in previous head injury scar, subsequently developing into glioma. Here we report a case of young patient presented with headache, seizures and gradual loss of vision. On investigation found to have brain tumor. Patient had head injury occurred 3 yrs back. It fulfills all the criteria required to establish traumatic origin, further supporting the association

Genomic characterization and epidemiology of an emerging SARS-CoV-2 variant in Delhi, India

Delhi, the national capital of India, experienced multiple severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) outbreaks in 2020 and reached population seropositivity of >50% by 2021. During April 2021, the city became overwhelmed by COVID-19 cases and fatalities, as a new variant, B.1.617.2 (Delta), replaced B.1.1.7 (Alpha). A Bayesian model explains the growth advantage of Delta through a combination of increased transmissibility and reduced sensitivity to immune responses generated against earlier variants (median estimates: 1.5-fold greater transmissibility and 20% reduction in sensitivity). Seropositivity of an employee and family cohort increased from 42% to 87.5% between March and July 2021, with 27% reinfections, as judged by increased antibody concentration after a previous decline. The likely high transmissibility and partial evasion of immunity by the Delta variant contributed to an overwhelming surge in Delhi

Estimating global injuries morbidity and mortality : methods and data used in the Global Burden of Disease 2017 study

Background: While there is a long history of measuring death and disability from injuries, modern research methods must account for the wide spectrum of disability that can occur in an injury, and must provide estimates with sufficient demographic, geographical and temporal detail to be useful for policy makers. The Global Burden of Disease (GBD) 2017 study used methods to provide highly detailed estimates of global injury burden that meet these criteria. Methods: In this study, we report and discuss the methods used in GBD 2017 for injury morbidity and mortality burden estimation. In summary, these methods included estimating cause-specific mortality for every cause of injury, and then estimating incidence for every cause of injury. Non-fatal disability for each cause is then calculated based on the probabilities of suffering from different types of bodily injury experienced. Results: GBD 2017 produced morbidity and mortality estimates for 38 causes of injury. Estimates were produced in terms of incidence, prevalence, years lived with disability, cause-specific mortality, years of life lost and disability-adjusted life-years for a 28-year period for 22 age groups, 195 countries and both sexes. Conclusions: GBD 2017 demonstrated a complex and sophisticated series of analytical steps using the largest known database of morbidity and mortality data on injuries. GBD 2017 results should be used to help inform injury prevention policy making and resource allocation. We also identify important avenues for improving injury burden estimation in the future

Association of respiratory symptoms and lung function with occupation in the multinational Burden of Obstructive Lung Disease (BOLD) study

Background Chronic obstructive pulmonary disease has been associated with exposures in the workplace. We aimed to assess the association of respiratory symptoms and lung function with occupation in the Burden of Obstructive Lung Disease study. Methods We analysed cross-sectional data from 28 823 adults (≥40 years) in 34 countries. We considered 11 occupations and grouped them by likelihood of exposure to organic dusts, inorganic dusts and fumes. The association of chronic cough, chronic phlegm, wheeze, dyspnoea, forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1)/FVC with occupation was assessed, per study site, using multivariable regression. These estimates were then meta-analysed. Sensitivity analyses explored differences between sexes and gross national income. Results Overall, working in settings with potentially high exposure to dusts or fumes was associated with respiratory symptoms but not lung function differences. The most common occupation was farming. Compared to people not working in any of the 11 considered occupations, those who were farmers for ≥20 years were more likely to have chronic cough (OR 1.52, 95% CI 1.19–1.94), wheeze (OR 1.37, 95% CI 1.16–1.63) and dyspnoea (OR 1.83, 95% CI 1.53–2.20), but not lower FVC (β=0.02 L, 95% CI −0.02–0.06 L) or lower FEV1/FVC (β=0.04%, 95% CI −0.49–0.58%). Some findings differed by sex and gross national income. Conclusion At a population level, the occupational exposures considered in this study do not appear to be major determinants of differences in lung function, although they are associated with more respiratory symptoms. Because not all work settings were included in this study, respiratory surveillance should still be encouraged among high-risk dusty and fume job workers, especially in low- and middle-income countries.publishedVersio

Global injury morbidity and mortality from 1990 to 2017 : results from the Global Burden of Disease Study 2017

Correction:Background Past research in population health trends has shown that injuries form a substantial burden of population health loss. Regular updates to injury burden assessments are critical. We report Global Burden of Disease (GBD) 2017 Study estimates on morbidity and mortality for all injuries. Methods We reviewed results for injuries from the GBD 2017 study. GBD 2017 measured injury-specific mortality and years of life lost (YLLs) using the Cause of Death Ensemble model. To measure non-fatal injuries, GBD 2017 modelled injury-specific incidence and converted this to prevalence and years lived with disability (YLDs). YLLs and YLDs were summed to calculate disability-adjusted life years (DALYs). Findings In 1990, there were 4 260 493 (4 085 700 to 4 396 138) injury deaths, which increased to 4 484 722 (4 332 010 to 4 585 554) deaths in 2017, while age-standardised mortality decreased from 1079 (1073 to 1086) to 738 (730 to 745) per 100 000. In 1990, there were 354 064 302 (95% uncertainty interval: 338 174 876 to 371 610 802) new cases of injury globally, which increased to 520 710 288 (493 430 247 to 547 988 635) new cases in 2017. During this time, age-standardised incidence decreased non-significantly from 6824 (6534 to 7147) to 6763 (6412 to 7118) per 100 000. Between 1990 and 2017, age-standardised DALYs decreased from 4947 (4655 to 5233) per 100 000 to 3267 (3058 to 3505). Interpretation Injuries are an important cause of health loss globally, though mortality has declined between 1990 and 2017. Future research in injury burden should focus on prevention in high-burden populations, improving data collection and ensuring access to medical care.Peer reviewe
