Murraya koenigii L. (family: Rutaceae), commonly referred to as curry leaf, is a highly valued plant due to its aroma and medicinal features. Two dominant AM species Glomus mosseae and Acaulospora laevis were isolated from the rhizospheric soil of M. koenigii. A pot experiment was performed to verify the interactive potential of G. mosseae and A. laevis alone or in combination with Pseudomonas fluorescens on M. koenigii. Various morphological and biochemical parameters were measured after 120 days. Overall results suggest that all co-inoculation treatments showed beneficial effects on all the growth, physiological and oil content. The overall results demonstrate that the co-inoculation of bioinoculants, like P. fluorescens with AM fungi, promotes higher AM colonization and spore number enhancing the nutrient acquisition, especially phosphorus (P), improving the rhizospheric condition of soil.

Background. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2 or COVID-19) continues to spread globally. It has become a major cause of concern for health care professionals all over the world. Objective. The aim of this study was to assess knowledge, awareness and hygiene practices regarding COVID-19 among private dental practitioners practicing in Tricity (Chandigarh, Panchkula and Mohali) in India during these critical times. Materials and Methods. A total of 245 private dentists participated in this cross-sectional survey and finally 215 constituted the final sample size. A self-administered, multiple choice type questionnaire (verified by a specialist) was administered to obtain information from the subjects. The questionnaire was divided into two parts and included 15 questions on knowledge and awareness regarding COVID-19. Statistical analysis was done using ANOVA and Student’s t-test. Results. Percentage of subjects who answered correctly regarding main symptoms of COVID-19 and primary mode of transmission was 87% and 82.5% respectively. One-third of the subjects were not aware regarding Personal Protective Equipment (PPE) to be used while rendering dental treatment. 75% of subjects were of the opinion that supportive care is the current treatment regime for COVID-19. Less than one-third of subjects (30.2%) reported high scores. Education level (p=0.018) and health sector profile (p=0.024) of the subjects were significantly associated with mean knowledge scores. Conclusion. The findings of the present study showed that some notable deficiencies in knowledge existed among dental professionals regarding some vital aspects of COVID-19. Therefore, there is an urgent need for improving dentists’ knowledge via health education and training programs. Further studies on the subject are also warranted once the situation normalizes.

Omicron, the new ‘Variant of Concern’ of SARS-CoV-2, is rapidly evolving into new sub-variants or sub-lineages (BA.1, BA.2 etc.). These sub-variants have higher transmissibility, decreased vaccine effectiveness and increased risk of reinfection. As a result, many nations across the globe are reporting surge in infections which is a matter of concern. Understanding Omicron and its sub-variants is vital for development of public health policy and preventing disease transmission. The present paper throws a spotlight on the newly detected sub-variants of Omicron as reported in ongoing researches which are available only in pre-print form and also the importance of a booster dose of the vaccine. Information regarding recent research on a new nasal vaccine formulation, which may be effective against the new variants, is also highlighted in the paper.

A new health threat in the form of a new variant of Covid-19 called Omicron has emerged globally in this holiday season. This new variant has been declared a variant of concern (VOC) by the World Health Organization and experts are expecting another wave of the pandemic. A lot still unknown about this variant and researchers worldwide are conducting studies to find the nature and characteristics of this mutated strain. Cases have begun to rise dramatically around the world and many countries have already imposed travel restrictions again to prevent disease transmission. It is being speculated that this particular variant has got tendency of immune escape and therefore can even infect fully vaccinated individuals. Vaccination and adhering to Covid-19 guidelines and protocols can curtail the spread of the virus. The present paper focuses on what is currently known about this variant, antigen diagnostic tests, importance of getting fully vaccinated and having booster dose etc. If we want to emerge from this pandemic, countries should practice vaccine equality and solidarity for the good of mankind.

Background. Prevalence and practices of tobacco usage in India are diverse and incongruent and Government of India has enacted various laws to overcome this burden. To make tobacco control measures effective and powerful, WHO introduced MPOWER in 2004 and India was one of the first countries that implemented the MPOWER. Objective. This study is aimed to quantify the implementation of MPOWER tobacco control policies in India. Material and Methods. In this retrospective analysis, data was gathered from the WHO MPOWER of India from 2015 to 2021. This analysis was based on the checklist which was designed previously by Iranian and international tobacco control specialists in their study on tobacco control. Results. In the present comparative analysis, India was categorized by scores and these were acquired from each indicator for each activity and 2021 year got the highest scores as compared to the previous year scores i.e. 27 in 2015. In context to individual indicators, noticeable increase in scores has been seen in both health warning on cigarette packages and adult daily smoking prevalence, whereas no progress was observed in smoking related policies. Conclusion. Although MPOWER programmes are widely accepted by the Indian government, but still substantial improvement in fewer sections is required.

A rapid malaria diagnostic test, OptiMAL®, was evaluated in a field based study in different epidemiological zones of India. The test can differentiate P. falciparum and non-P. falciparum malaria. The OptiMAL test is based on a dipstick principle for detection of parasite lactate dehydrogenase (pLDH). Since it has been shown that HRP-2 antigen can be detected even after parasitological cure, pLDH detection is more suited for follow up of patients. The sensitivity and specificity of the test compared to microscopy was evaluated in 699 febrile patients from all the study sites. The sensitivity and specificity obtained with the OptiMAL test was 87.9% (79-100%) and 98.9% (95.4-100%) respectively, for diagnosis of falciparum malaria while sensitivity and specificity of OptiMAL for diagnosis of non-falciparum malaria (P. vivax) were 93% (89.2-100%) and 96.8% (94.3-100%), respectively. However, failure to detect high parasitaemia in one patient with P. falciparum malaria is of particular concern. Although the rapid tests have a definite role in diagnosis of malaria especially where expertise for microscopy is not available, the cost of the test kits remains a major obstacle to their wide spread use in developing countries.
