A randomized, controlled, blinded, parallel group, clinical trial to study the role of Ayurcov (AyurCoro3), one day regimen as an adjuvant therapy for COVID-19 disease management, at dedicated Covid Hospital (DCH) in India.

INTRODUCTION: Limited treatment options exist for COVID-19 infections; thus, attempts from complementary and alternative systems (CAM) of medicine are being explored as possible therapeutic options. Ayurcov is a formulation made of ingredients mentioned in Ayurveda. These constituents have proven antiviral, detoxifying, immune-modulating, and bio-enhancing properties. The present study was carried out to evaluate the therapeutic effect and safety of Ayurcov in patients with various severity states of COVID-19 infections. METHODS: A randomized, single blinded, controlled trial was carried out in adults diagnosed with mild-to-moderate, and severe COVID-19 infections confirmed by real time reverse transcriptase polymerase chain reaction (rRTPCR) test. The interventional group received three doses of 'Ayurcov'. It is constituted of Haridra Churna (Curcuma longa), Go ark (Bos Indicus Distilled Urine), Sphatika (Alum), Sita (Rock Candy), Godugdham (Bos Indicus Milk) milk, Goghritam (Bos Indicus ghee) on Day 1, as an adjuvant to the standard of care, and the control group received only the standard of care. Key outcomes included: proportion of patients and time taken for symptom resolution, reduction in the rRT-PCR Ct values, safety, and functional status until 42 days after discharge. RESULTS: Ninety patients with mild-to-moderate and 30 patients with severe COVID-19 disease were recruited. It was observed that significantly more proportions of patients receiving Ayurcov had symptom relief much earlier than control group. Additionally, the interventional group showed significantly lower rRT-PCR Ct values. However, a shorter time of resolution of symptoms was observed with the interventional group in the mild to moderate category but not with those having severe symptoms. Similarly, a significantly better functional status was observed with interventional group on days 7 and 28 after discharge. Ayurcov was not observed with higher risks of any adverse/serious adverse events. CONCLUSIONS: Ayurcov as adjuvant with standard of care was associated with significantly earlier resolution of COVID-19 related symptoms than standard of care alone.

Prevalence of Consumption of Smokeless Tobacco Products and Exposure to Second-Hand Smoke among Women in the Reproductive Age Group in a Rural Area of Koppal, Karnataka.

BACKGROUND: Tobacco use is one of the most important causes of death and disease globally. Nearly one-third of the population in India uses tobacco, and smokeless form is culturally acceptable even among women. OBJECTIVES: (1) To estimate the prevalence of consumption of smokeless tobacco (SLT) products among women in the reproductive age group in the study setting. (2) To determine the various factors associated with the consumption of SLT. (3) To estimate the prevalence of exposure to second-hand smoke among the study participants. MATERIALS AND METHODS: A cross-sectional study was conducted in the field area of primary health center Irkalgad, Koppal in March 2018. A cluster sampling technique was used and a total of 829 women were included. Data were collected using pretested and semi-structured questionnaire and analyzed using the Epi info software version 3.5.4 (Centers for Disease Control and Prevention" (CDC), Atlanta, Georgia, United States of America). RESULTS: The prevalence of consumption of SLT products was 17.85%, and the most common product consumed was tobacco with betel quid. Tobacco consumption was found to be significantly associated with age, literacy, marital, and employment status of the study participants. CONCLUSION: The present study concludes that SLT consumption is high among women in the reproductive age group in the study setting and identifies multiple determinants for effective planning of interventions.

Mentha arvensis essential oil suppressed airway changes induced by histamine and ovalbumin in experimental animals.

The present investigation aimed to evaluate the activity of the essential oil of Mentha arvensis L. on exogenously induced bronchoconstriction in experimental animals. The anti-asthmatic effect of M. arvensis essential oil (MAEO) was studied using histamine aerosol-induced bronchoconstriction in guinea pigs and ovalbumin (OVA) sensitised albino mice. Treatment with M. arvensis oil significantly (p < 0.001) increased the time of preconvulsive dyspnoea in histamine-induced guinea pigs. Oral treatment of MAEO significantly (p < 0.001) decreased absolute eosinophil count, serum level of IgE and the number of eosinophils, neutrophils in BALF. Histopathological examination of lungs showed that essential oil rescinded bronchial asthma. The present investigation provides evidence that MAEO relaxes bronchial smooth muscles and suppressed immunological response to OVA.

Effect of Angelica glauca essential oil on allergic airway changes induced by histamine and ovalbumin in experimental animals.

OBJECTIVE: Angelica glauca Edgew (Apiaceae) is used in traditional medicine for treatment of several diseases including bronchial asthma. The present investigation was aimed to evaluate broncho-relaxant activity of A. glauca essential oil in histamine and ovalbumin (OVA)-induced broncho constriction in experimental animals. MATERIALS AND METHODS: Airway was induced using histamine aerosol in guinea pigs (n = 24) and OVA aerosol in albino mice (n = 24). The number of inflammatory cells, namely, absolute eosinophils count in blood, total immunoglobulin E (IgE) in serum, eosinophils, and neutrophils in bronchoalveolar lavage fluid (BALF) and histopathological examination of lung tissues were investigated in A. glauca oil and dexamethasone-treated groups. A. glauca oil 200 µL/kg was given orally, and dexamethasone 2 mg/kg was given intraperitoneal. Both the treatments were repeated daily for 7 days. Results were analyzed by one-way ANOVA, and P ≤ 0.05 was considered statistically significant. RESULTS: Treatment with A. glauca essential oil significantly (P < 0.001) increased the time of preconvulsive dyspnea in histamine-induced guinea pigs. Oral treatment of A. glauca oil significantly (P < 0.001) decreased absolute blood eosinophil count (from 325 ± 3.69 to 200 ± 3.05 cells/mm3), serum level of IgE (from 6.10 ± 0.05 to 0.70 ± 0.08 IU/L), and the number of eosinophils (from 11.0% ±1.41% to 3.0% ±0.51%), neutrophils (from 13.0% ±1.12% to 5.0% ±1.39%) in BALF. Histopathological changes observed in lungs of untreated group were marked suppressed by treatment with A. glauca oil. CONCLUSION: The essential oil of A. glauca has bronchorelaxation in both histamine and OVA-induced bronchoconstriction in animals. The traditional use of A. glauca against asthma could be attributed to its bronchodilator property as observed in the present study.

Microwave assisted synthesis of dihydrobenzo[4,5]imidazo[1,2-a]pyrimidin-4-ones; synthesis, in vitro antimicrobial and anticancer activities of novel coumarin substituted dihydrobenzo[4,5]imidazo[1,2-a]pyrimidin-4-ones.

The present article describes the synthesis of dihydrobenzo[4,5]imidazo[1,2-a]pyrimidin-4-one (2a-h) under microwave irradiation. The product was obtained in excellent yield (74-94%) in a shorter reaction time (2 min). These molecules (2a, b) further reacted with various substituted 4-bromomethylcoumarins (3a-f) to yield a new series of coumarin substituted dihydrobenzo[4,5]imidazo[1,2-a]pyrimidin-4-ones (4a-h). The structure of all the synthesized compounds were confirmed by spectral studies and screened for their in vitro antibacterial activity against three Gram-positive bacteria viz., Staphylococcus aureus, Enterococcus faecalis, Streptococcus mutans and three Gram-negative bacteria viz., Escherichia coli, Klebsiella pneumonia, Pseudomonas aeruginosa and antifungal activity against Candida albicans, Aspergillus niger, Aspergillus fumigatus, Aspergillus flavus, Fusarium oxysporum, Penicillium chrysogenum and anticancer activity against Dalton's Ascitic Lymphoma (DAL) cell line. In general, all the compounds possessed better antifungal properties than antibacterial properties. The coumarin substituted dihydrobenzo[4,5]imidazo[1,2-a]pyrimidin-4-one (4g) (R = i-Pr, R1 = 6-Cl) was found to be the most potent cytotoxic compound (88%) against Dalton's Ascitic Lymphoma cell line at the concentration of 100 µg/mL.

Synthesis and antimicrobial studies on novel sulfonamides containing 4-azidomethyl coumarin.

A series of new and novel coumarin-6-sulfonamides with a free C4-azidomethyl group have been synthesized as antimicrobials in three steps starting from 7-methyl-4-bromomethylcoumarin 1. The reaction of 1 with chlorosulfonic acid was found to yield the corresponding 6-sulfonylchloride 2, which when treated with sodium azide led to intermediate 3. The title sulfonamides 5a-y were obtained from the reaction of 3 with various aromatic amines 4 in refluxing benzene. The chemical structures of the compounds were elucidated by IR, NMR and LC-MS spectral data. All the synthesized compounds have been screened for their in vitro anti-bacterial and anti-fungal activities. Some of the compounds have been found to be active against both bacterial species at a concentration of 1 microg/mL.

Hazardous alcohol use in rural southern India: nature, prevalence and risk factors.

BACKGROUND: There is a dearth of data on the hazardous use of alcohol in rural India. METHODS: We examined the nature, prevalence and factors associated with hazardous use of alcohol among men in a rural community in southern India. We used stratified sampling to select subjects from the Kaniyambadi block and employed 'AUDIT', a standard instrument, to assess the use of alcohol. RESULTS: The prevalence of life-time use, use in the past year and hazardous use of alcohol was 46.7%, 34.8% and 14.2%, respectively. Using Indian made foreign liquor (OR 20.51; 95% CI 8.81-47.75) and living in a village which brewed illicit alcohol (OR 2.82; 95% CI 1.39-5.72) were risk factors for hazardous use while education (OR 0.39; 95% CI 0.21-0.72) was protective. These factors remained significantly associated with hazardous use after adjusting for age and education using logistic regression. CONCLUSION: The relationship between the availability of illicit and commercial alcohol and its hazardous use suggests the need for an alcohol policy which takes into account health and economic issues and also implements the law to prevent the negative impact of problem drinking.

Pyrene-derived novel one- and two-component organogelators.

A new class of alkyl-chain-appended pyrene derivatives 4-14 were synthesized and evaluated for their gelation abilities. Depending on the nature of the linking group, these compounds gelated a number of organic solvents, either in the presence or in the absence of the acceptor molecule 2,4,7-trinitrofluorenone (TNF). Compounds with ester, ether, or alkyl linkages gelated a number of hydroxylic and hydrocarbon solvents by means of a charge-transfer interaction with TNF, while compounds with amide, urethane and urea linkers formed gels on their own in a variety of solvents by means of pi-pi stacking and hydrogen-bonding interactions. The Xray crystal structure of urethane (S)-12 showed hydrogen-bonding and stacking features, as suggested by the model. The gels obtained were investigated by spectroscopic and electron microscopic techniques which provided structural insights.

Atrial septal aneurysm associated with systemic embolism and interatrial right-to-left shunt.

Prior to the advent of two-dimensional echocardiography, atrial septal aneurysm was rarely diagnosed during life. In this article, two-dimensional echocardiography identified an atrial septal aneurysm as the site of intracardiac right-to-left shunting, causing hypoxemia in a patient with acute right ventricular infarction. In addition to this rare presentation, the patient also had systemic embolism, a known complication of atrial septal aneurysms.
