A randomized controlled trial of ketorolac for prevention of headache related to electroconvulsive therapy  [PDF]
Keith G. Rasmussen
Pain Studies and Treatment (PST) , 2013, DOI: 10.4236/pst.2013.12002
Abstract: Background and Purpose: Headache is one of the most common side effects of electroconvulsive therapy (ECT), with a reported prevalence as high as 45%. Typical pharmacologic measures include aspirin, acetaminophen, or nonsteroidal anti-inflammatory medications. Among the latter, ketorolac may be especially advantageous in that it can be administered intravenously right before a treatment. The primary aim of this study was to measure the efficacy of intravenous ketorolac administration for the prevention of post-ECT headache at the first treatment session. Methods: Sixteen patients were assigned to the control group, while eight patients were assigned to the ketorolac treatment group (8 males, 16 females; mean age ± standard deviation = 46 ± 13.5 years). Statistical analysis consisted of a one-way analysis of variance using the two-sample test. We utilized a post-ECT headache severity scale from zero (no headache) to 3 (severe headache). Results:The mean score for the control group was 1.3 (±1.1), while the mean score for the ketorolac treatment group was 1.2 (±1.1), p = 0.86 (not significant). Conclusions: Ketorolac administration does not decrease the incidence of post ECT headache at the first treatment session. It is possible that ketorolac may be effective at subsequent treatments for patients with particularly bothersome headaches after the first treatment. Implications: Ketorolac should not be routinely used at the first treatment session to prevent headache associated with ECT.
Minimizing Costs Can Be Costly
Rasmus Rasmussen
Advances in Decision Sciences , 2010, DOI: 10.1155/2010/707504
Abstract: A quite common practice, even in academic literature, is to simplify a decision problem and model it as a cost-minimizing problem. In fact, some type of models has been standardized to minimization problems, like Quadratic Assignment Problems (QAPs), where a maximization formulation would be treated as a “generalized” QAP and not solvable by many of the specially designed softwares for QAP. Ignoring revenues when modeling a decision problem works only if costs can be separated from the decisions influencing revenues. More often than we think this is not the case, and minimizing costs will not lead to maximized profit. This will be demonstrated using spreadsheets to solve a small example. The example is also used to demonstrate other pitfalls in network models: the inability to generally balance the problem or allocate costs in advance, and the tendency to anticipate a specific type of solution and thereby make constraints too limiting when formulating the problem.
Diversity and abundance of orchid bees (Hymenoptera: Apidae, Euglossini) in a tropical rainforest succession
Rasmussen, Claus;
Neotropical Entomology , 2009, DOI: 10.1590/S1519-566X2009000100006
Abstract: euglossine bee males are easily lured to chemical baits imitating natural fragrances gathered by bees, providing a widely applied measure for estimating the diversity and abundance of euglossines. in here, i report the composition of euglossine bees in three lowland rainforest habitats of peru, a primary old forest, a reforested and managed forest, and a very disturbed forest. a total of 2,072 males of euglossine were collected, belonging to 33 species and four genera. although a comparable diversity relative to other studies from the amazonian region was found, no significant differences among the sampled areas were detected. perhaps, the short time and low intensity surveys here used (< 3 months) were not good enough indicators of forest disturbance without additional data. compared to other major studies on the euglossine bee fauna, loreto is most similar to the species assemblage reported from lowland rainforest in brazil (manaus), central peru (panguana) and southern peru (tambopata).
Thermodynamic constraints on effective energy and mass transfer and catchment function
C. Rasmussen
Hydrology and Earth System Sciences (HESS) & Discussions (HESSD) , 2012,
Abstract: Understanding how water, energy and carbon are partitioned to primary production and effective precipitation is central to quantifying the limits on critical zone evolution. Recent work suggests quantifying energetic transfers to the critical zone in the form of effective precipitation and primary production provides a first order approximation of critical zone process and structural organization. However, explicit linkage of this effective energy and mass transfer (EEMT; W m 2) to critical zone state variables and well defined physical limits remains to be developed. The objective of this work was to place EEMT in the context of thermodynamic state variables of temperature and vapor pressure deficit, with explicit definition of EEMT physical limits using a global climate dataset. The relation of EEMT to empirical measures of catchment function was also examined using a subset of the Model Parameter Estimation Experiment (MOPEX) catchments. The data demonstrated three physical limits for EEMT: (i) an absolute vapor pressure deficit threshold of 1200 Pa above which EEMT is zero; (ii) a temperature dependent vapor pressure deficit limit following the saturated vapor pressure function up to a temperature of 292 K; and (iii) a minimum precipitation threshold required from EEMT production at temperatures greater than 292 K. Within these limits, EEMT scales directly with precipitation, with increasing conversion of the precipitation to EEMT with increasing temperature. The state-space framework derived here presents a simplified framework with well-defined physical limits that has the potential for directly integrating regional to pedon scale heterogeneity in effective energy and mass transfer relative to critical zone structure and function within a common thermodynamic framework.

Abstract: F rste gang publiceret i UNEV nr. 8: Tilrettel ggelse af efter- og videreuddannelse p universitetet, nov. 2006, red. Sanne Almeborg og Tom Nyvang. ISSN 1603-5518. Kompetencel ft skal skrives ind i budgetterne, siger Dorthy Rasmussen, leder af Kompetenceenheden ved K benhavns Universitet i denne kronik. Efter- og videreuddannelse er en b redygtig investering, der bidrager positivt p alle niveauer: i samfundet, i virksomheder og organisationer og for det enkelte individ. Universiteterne har her meget at byde p , men kvalitet koster penge. Er det derfor ikke p tide, sp rger Dorthy Rasmussen, at f skrevet kompetencel ft ind i budgetterne i lighed med ferie og pension?

Abstract: Dette er en "syntese" af opl g og diskussioner p SMIDs rsm de om internationaliseringen af TV-udbuddet. Artik- len indledes med en henvisning til den voldsomme presse- debat i december 86 om rimeligheden i at beskytte det danske hybridnet (landsd kkende kabel-TV) ved at op- retholde et forbud mod "privat" nedtagelse af udenlansk TV fra kommunicationssatellitterne. Begrebet "public service" er ved at v re fast inventar i den internationale TV-debat. Det er hentet fra England og USA, hvor det betyder ikke-reklamefinansieret TV, som i mange lande er p lagt s rlige programforpligtigelser (alsidighed, objektivitet, hensyn til kulturelle mindretal etc.) mod at have f et retten til at opkr ve licens.
