An evaluation of knowledge, attitude and perception about adverse drug reactions and pharmacovigilance among intern doctors in a medical college teaching hospital of Sangli

Background: Underreporting of various adverse drug reactions (ADRs) by consultants is a common incurable problem. National pharmacovigilance program is one of the ongoing programs to monitor the adverse drug reactions & reporting at the earliest to the nearby AMCs. As medical interns are budding doctors, the focus of this study was to evaluate the knowledge, attitude and perception about ADRs and pharmacovigilance in them.Methods: A cross section questionnaire-based study was conducted after approval by our institutional ethics committee pretested and validated questions consisting of 20 questions (knowledge, attitude, perception) were administrated to medical interns. The filled questionnaires were collected and analysed.Results: In our study, medical interns have fair enough idea about ADR and pharmacovigilance. In knowledge domain they were aware of term ADRs (100%), pharmacovigilance (72.6%). In attitude domain majority of interns (80.6%) known availability of ADR forms, compulsory of pharmacovigilance unit (90.3%). In perception domain very poor response from interns, not even a single intern had reported any ADR filled form and they don’t know meaning of re-challenge and de-challenge, very few interns (9.7%) know how to manage the ADRs in emergency conditions.Conclusions: Under reporting problem can be improved by doing more teaching activities at undergraduate level and intern’s level including various workshops, CMEs, problem-based teaching of adverse reactions in their curriculum. These exercises will improve their reporting frequency and sensitize the interns from the undergraduate days itself in their upcoming clinical practice in community

A study of assessment of knowledge, attitude and practice of antibiotic stewardship among healthcare providers in a tertiary care hospital of Sangli

Background: Antimicrobials are routinely used for variety of clinical conditions but are also misused leading to drug resistance bacteria in clinical practice. Consultants can gain the knowledge about it and can also have the depth of problem faced, their prescribing behavior mainly depends on their attitude and understanding of condition. Our aim of this study is to evaluate the knowledge and beliefs about antibiotics prescribing among health care workers in a tertiary care hospital of Sangli. Methods: Our present study was conducted in the Bharati hospital, BV (DU) medical college and hospital, Sangli. Ethical clearance from the institutional ethics committee was obtained and it was, cross-sectional questionnaire-based study carried out in the form of a survey in which a pretested, semi-structured, validated questionnaire was provided to junior residents, senior residents and faculty of different specialties and responses were recorded. Questionnaire comprises of 9 in knowledge, 10 in attitude and 10 in practice section. Results: Out of all participants 84.5% believed that no need of antibiotics for running and blocked nose. Majority 89.6% were expressed that sample culture should be sent before starting antibiotics. 90.4% participants believed that education of patients will help. Only 76.8% strictly adhere to the antibiotic policy of our hospital. Conclusions: The present study on antibiotic usage gives useful information about the knowledge, attitudes and practices of prescribers and help plan suitable educational modifications that aim at improving the antimicrobial prescribing and minimizing the development of drug resistance in our developing country

Global plant trait relationships extend to the climatic extremes of the tundra biome

The majority of variation in six traits critical to the growth, survival and reproduction of plant species is thought to be organised along just two dimensions, corresponding to strategies of plant size and resource acquisition. However, it is unknown whether global plant trait relationships extend to climatic extremes, and if these interspecific relationships are confounded by trait variation within species. We test whether trait relationships extend to the cold extremes of life on Earth using the largest database of tundra plant traits yet compiled. We show that tundra plants demonstrate remarkably similar resource economic traits, but not size traits, compared to global distributions, and exhibit the same two dimensions of trait variation. Three quarters of trait variation occurs among species, mirroring global estimates of interspecific trait variation. Plant trait relationships are thus generalizable to the edge of global trait-space, informing prediction of plant community change in a warming world.Peer reviewe

Tundra Trait Team: A database of plant traits spanning the tundra biome

Abstract Motivation: The Tundra Trait Team (TTT) database includes field-based measurements of key traits related to plant form and function at multiple sites across the tundra biome. This dataset can be used to address theoretical questions about plant strategy and trade-offs, trait–environment relationships and environmental filtering, and trait variation across spatial scales, to validate satellite data, and to inform Earth system model parameters. Main types of variable contained: The database contains 91,970 measurements of 18 plant traits. The most frequently measured traits (> 1,000 observations each) include plant height, leaf area, specific leaf area, leaf fresh and dry mass, leaf dry matter content, leaf nitrogen, carbon and phosphorus content, leaf C:N and N:P, seed mass, and stem specific density. Spatial location and grain: Measurements were collected in tundra habitats in both the Northern and Southern Hemispheres, including Arctic sites in Alaska, Canada, Greenland, Fennoscandia and Siberia, alpine sites in the European Alps, Colorado Rockies, Caucasus, Ural Mountains, Pyrenees, Australian Alps, and Central Otago Mountains (New Zealand), and sub-Antarctic Marion Island. More than 99% of observations are georeferenced. Time period and grain: All data were collected between 1964 and 2018. A small number of sites have repeated trait measurements at two or more time periods. Major taxa and level of measurement: Trait measurements were made on 978 terrestrial vascular plant species growing in tundra habitats. Most observations are on individuals (86%), while the remainder represent plot or site means or maximums per species. Software format: csv file and GitHub repository with data cleaning scripts in R; contribution to TRY plant trait database (www.try-db.org) to be included in the next version release

Heteroatom-Containing Porphyrin Analogues

The heteroatom-containing porphyrin analogues or core-modified porphyrins that resulted from the replacement of one or two pyrrole rings with other five-membered heterocycles such as furan, thiophene, selenophene, tellurophene, indene, phosphole, and silole are highly promising macrocydes and exhibit quite different physicochemical properties compared to regular azaporphyrins. The properties of heteroporphyrins depend on the nature and number of different heterocycle(s) present in place of pyrrole ring(s). The heteroporphyrins provide unique and unprecedented coordination environments for metals. Unlike regular porphyrins, the monoheteroporphyrins are known to stabilize metals in unusual oxidation states such as Cu and Ni in +1 oxidation states. The diheteroporphyrins, which are neutral macrocycles without ionizable protons, also showed interesting coordination chemistry. Thus, significant progress has been made in last few decades on core-modified porphyrins in terms of their synthesis, their use in building multiporphyrin arrays for light harvesting applications, their use as ligands to form interesting metal complexes, and also their use for several other studies. The synthetic methods available in the literature allow one to prepare mono- and diheteroporphyrins and their functionalized derivatives, which were used extensively to prepare several covalent and noncovalent heteroporphyrin-based multiporphyrin arrays. The methods are also developed to synthesize different hetero analogues of porphyrin derivatives such as heterocorroles, heterochlorins, heterocarbaporphyrinoids, heteroatom-substituted confused porphyrins, and so on. This Review summarizes the key developments that have occurred in heteroporphyrin chemistry over the last four decades

Square-edge intraocular lens versus conventional round-edge intraocular lens in prevention of posterior capsule opacification: A randomized clinical trial

Aim: To determine whether square-edge polymethyl methacrylate (PMMA) intraocular lens (IOL) is superior in preventing clinically significant posterior capsule opacification (PCO) and better visual outcome when compared with round-edge PMMA IOL in manual small-incision cataract surgery (MSICS). Settings and Design: Tertiary care hospital-based randomized controlled clinical trial. Materials and Methods: A randomized clinical trial of 1 year in which 128 patients were randomized into two groups to receive round-edge IOLs (Group A) or square-edge IOLs (Group B) after MSICS and followed up for 10 months; during follow-up, the best corrected visual acuity, grades, and type of PCO were documented. Statistical Analysis Used: Data analysis was done using chi-square test. Results: Out of 128 patients, the incidence of PCO was 83.6%, out of which 85.9% were in Group A and 81.2% were in Group B. Visual outcome was better in Group B, which was statistically significant (0.003). The fibrous type of PCO was the commonest type seen in the study irrespective of the group. There was less incidence of PCO in capsulorrhexis (with relieving incisions) and complete cortical cleanup cases. Difference in neodymium-doped yttrium aluminum garnet; Nd:Y3Al5O12 (Nd:YAG) laser capsulotomy rates were not statistically significant between the two groups (P = 0.784). Conclusions: This study showed that square edge PMMA IOLs had less clinically significant PCO rates and better visual outcome when compared to round-edge PMMA IOLs
