Analysis of usage of diuretics in medical intensive care unit of SIMS-Shimoga a tertiary care hospital
Get PDFBackground: Patients are admitted in the intensive care unit (ICU) with a history of various acute and chronic clinical conditions associated with organ failures. Compared to the patients admitted in the general wards the mortality and morbidity are high in ICU patients. The patients in ICU are subjected to multiple drugs; diuretic agents are liberally and deliberately used in this setup despite the lack of evidence supporting their benefits.Methods: The main aim of the study was to know the extent of use of diuretics in the ICU set up, to categorize the use of diuretics in different clinical conditions and different classes of diuretics used. The study also tried to determine adverse events and outcome in critically ill patients. The study was a retrospective cross-sectional of 3 months duration conducted in all patients admitted in the medical ICU of the tertiary care center. The study mainly concentrated on the usage of diuretics and related aspects.Results: Loop diuretics (54.81%) composed the major class, thiazides (30.84%). Potassium sparing diuretics (7%) and osmotic diuretics (7%) and carbonic anhydrase inhibitors (1%) were the other class of diuretics. The classes of drugs used in ICU along with diuretics were antibiotics (30%), analgesics (9.5%), anti-inflammatory (6.36%), and drugs acting on blood (10.18%) of total drugs used in ICU. Antacids/laxatives (7.3%) and antiemetic (4.8%), the rest of drugs (15%) of drugs used in ICU.Conclusion: In almost 95% of cases, the combination of other drugs along with diuretics was considered to be rational
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Retrospective study on cost distribution of antiretroviral therapy in a tertiary care hospital
Get PDFBackground: Acquired immunodeficiency syndrome (AIDS) is caused by human immunodeficiency virus (HIV), which is an RNA virus. The first case of AIDS in human beings was reported in 1981, and now spread of HIV infection is alarmingly high with around 20 million deaths. The objective of the study was to determine the cost distribution of antiretroviral therapy among autoimmune deficiency syndrome (AIDS) patient attending the anti-retroviral therapy (ART) center of the tertiary care center.Methods: The objective of the study was to determine the cost distribution of antiretroviral therapy among AIDS patient attending the ART center of the tertiary care center. The study was retrospective, 20 patients included in different age groups and categories the cost incurred toward patients were divided under different heads: medication, laboratory diagnosis, transport, and miscellaneous costs.Results: It was found that major part of the cost is spent on drugs. The cost of transport and lab diagnosis varied based on age and stage of the disease. Miscellaneous costs were also high and were proportional to other costs.Conclusion: HIV infected population is more likely to have a lower socioeconomic status which has varied effect on the effectiveness of highly active ART. Some of the problems faced by them are access to health care, transport, economic instability, etc. all these factors have an impact on outcome of treatment. Overall it can be found that preventive measure than treating has better impact on quality of life
Study on organophosphate poisoning analysis and pharmacotherapeutic outcome in tertiary care hospital
Get PDFBackground: Organophosphate (OP) poisoning is the most common cause of poisoning and suicides in rural India as it is easily available and more often used in agriculture as a pesticide. In the present days, death due to OP is mainly due to draught, scarcity of rains and debt.Methods: The main objective of the study was to know the sociodemographic patterns, mode of presentation and outcome of treatment in the OP poisoning case that were admitted and treated in the tertiary care hospital attached to SIMS Shimoga. The study was a retrospective which included 120 patients at the point.Results: It was found that OP poisoning was commoner in males than in females. The male: female ratio was 1.5:1. OP associated deaths were the more common in agriculture based socioeconomic group than others mainly due to easy accessibility. Muscarinic manifestations were the common presentation in most of the patients. It was found that in the majority of the cases atropine and pralidoxime were the commonly used antidotes and recover rate was 93%.Conclusion: Consumption of large doses of OP and delayed treatment due to late admission were associated with increased mortality. Awareness programs regarding safe use and strict policies governing the availability of OP will help in saving many lives due to OP poisoning
Genotoxic evaluation of ornidazole and secnidazole in albino mice: an experimental study
Get PDFBackground: The present study was planned to explore the genotoxic potential of some commonly used antimicrobials like ornidazole and secnidazole in swiss albino mice.Methods: Therapeutic equivalent doses of ornidazole and secnidazole were given by intra peritoneal route. Single dose in individual groups of mice (n=5 in each) was administered for acute study. Doses were repeated every 24 hrs for 7 times in additional groups of mice (n=5 in each) for sub-acute study. Cyclophosphamide served as positive control while normal saline as negative control. After 24 hrs of single dose (acute study) and last dose of drug administration in sub-acute study, about 0.5 ml of blood was collected by retro orbital sinus for comet assay as described earlier (Rojas E et al, 1999) and later the mice were sacrificed to aspirate the femoral bone marrow for micronucleus test as described earlier by described by Schmid W (1975). In comet assay, the total comet length and head diameter was measured under microscope using ocular & stage micrometer to calculate comet tail length. In micronucleus assay, the stained bone marrow tissue smears were scored for the frequency of micronucleated polychromatic erythrocytes (MnPCE) and also the ratio between polychromatic erythrocytes (PCE) to normochromic erythrocytes (NCE) was obtained.Results: It was analyzed by one-way ANOVA followed by Dunnet’s multiple comparison tests. Significant (P< 0.01) increase in comet tail length and percentage of micronucleated polychromatic erythrocytes (% MnPCE) was observed in groups treated with single and multiple doses of Cyclophosphamide whereas ornidazole and secnidazole treated groups did not show any significant changes.Conclusions: The results indicate that Ornidazole and secnidazole are devoid of genotoxicity.
Drug utilization study on antidiabetic medications at SIMS-Shimoga a tertiary care hospital
Get PDFBackground: Diabetes mellitus (DM) refers to a group of common metabolic disorders that share the phenotype of hyperglycemia. DM is a leading cause of blindness, end stage renal disease, and nontraumatic lower extremity amputations. The objective of the study was to evaluate the drug utilization pattern of antidiabetic medications at a tertiary care hospital.Methods: Demographic details of the patient were noted. Evaluation of the written prescription was carried out according to the requirements in case record form followed by computerization of data and analysis.Results: DM was almost equal in male (51%) and females (49%), the risk of DM was high after 40 years of age. Out of all the case records and prescriptions reviewed it was found that 23% had Type 1 DM, and 77% had Type 2 DM. In 46.35% cases, there was a family history of DM while in 47.44% cases it was absent, 6% were unaware. The average number of drugs per prescription was 3.26±0.24 and antidiabetic drugs at 1.72±0.28. Insulin alone was prescribed in 25.54% cases. Single antidiabetic agents as lone drugs were seen in 39.05%; combined oral antidiabetic drugs accounted for 25.54% cases. The combination of insulin and oral antidiabetic agents were prescribed in 9.85% cases.Conclusion: Metformin was the oral hypoglycemic agents, which was the most frequent prescribed as was insulin and its analogs. These drugs being essential in the treatment of diabetic patients should be made available to patients all the time
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
