RESUMEN
OBJECTIVES: The primary objective was to determine the financial resources allocated to docusate at a representative U.S. tertiary care center. Secondary objectives included comparing docusate utilization between two tertiary care centers, and exploring alternative uses for the funds spent on docusate. METHODS: The study population included all patients 18 years and older admitted to University Hospital in Newark, New Jersey. Every scheduled docusate prescription for the study population between January 1st, 2015 and December 31st, 2019 was collected. The annual total cost associated with docusate use per year was calculated. The 2015 data from this study and a 2015 McGill University Health Centre study were compared. Also, alternative uses for the money utilized on docusate were assessed. RESULTS: Over the study period, 37,034 docusate prescriptions and 265,123 docusate doses were recorded. The average cost of prescribing docusate was $25,624.14 per year and $49.37 per hospital bed per year. A comparison between the 2015 data of University Hospital and McGill showed that McGill prescribed 107 doses and spent $10.09 more per hospital bed than University Hospital. Finally, alternative uses for the average yearly spending on docusate equated to 0.35 the salary of a nurse, 0.51 the salary of a secretary, 20.66 colonoscopies, 27.00 upper endoscopies, 186.71 mammograms, 1,399.37 doses of polyethylene glycol 3350, 3,826.57 doses of lactulose, or 4,583.80 doses of psyllium. CONCLUSION: A single average size tertiary care hospital spent about $25,000 yearly on docusate despite its lack of clinical effectiveness. While this amount is small compared to an overall hospital budget, when considering likely comparable docusate use at the U.S's 6,090 hospitals, the economic burden of docusate becomes significant. The funds currently being used on docusate could be redirected to alternative, more cost-effective purposes.

Airway burns cause delayed collapse of airways due to airway edema. Transferring clinicians are trained to intubate at the first suspicion of airway collapse, which can lead to vague reasons for intubation such as "airway protection." Intubation, however, is not without risks, such as pneumonia and death. The objective of this research review is to compare pre-burn center intubations with those performed at burn centers and compare rates of pneumonia, mortality, and time to extubation. A systematic review of articles from MEDLINE and CINAHL Plus was performed to identify eligible trials and observational studies that compared pre-burn center intubations with those performed at burn centers between the years 2014 and 2018. Four studies met eligibility requirements. There were mixed results on the correlation of pre-burn center intubation with pneumonia and death; however, pre-burn center patients were more likely to have earlier extubation times, which points to potentially unnecessary intubations. Clinicians should be aware of the increased mortality and morbidity associated with intubation. Providers should use objective evidence-based tools such as the ABA (American Burn Association) and Denver criteria to determine the need for intubation to avoid unnecessary intubations and their potential complications.

In addition to inhibiting cholesterol biosynthesis, statins also inhibit the formation of isoprenoid intermediates, which are required for the activation of the Rho/Rho kinase (ROCK) pathway. Increased ROCK activity has been implicated in causing endothelial dysfunction and atherosclerosis. However, it is not known whether statins, at doses used to lower cholesterol levels, inhibit ROCK activity in humans with atherosclerosis. Furthermore, it is not known whether lipophilic and hydrophilic statins differ in their ability to inhibit ROCK activity. Accordingly, we enrolled 30 men with stable atherosclerosis (low-density lipoprotein [LDL] > or =100 mg/dL) in a randomized, double-blind study comparing equivalent LDL-lowering doses of a hydrophilic statin (rosuvastatin 10 mg once a day) with a lipophilic statin (atorvastatin 40 mg once a day) for 28 days. We assessed the change in lipids, ROCK activity, and flow-mediated dilation (FMD) of the brachial artery before and after statin therapy. Both treatment groups exhibited comparable 30% to 32% and 42% to 45% reductions in total and LDL cholesterol, respectively. Only atorvastatin reduced triglycerides, and neither statin altered high-density lipoprotein cholesterol. Whereas both statins inhibited ROCK activity (p <0.0001), the extent of inhibition was greater with rosuvastatin (18 +/- 2% vs 8 +/- 2%, p = 0.0006). Statins also improved FMD from 7.4 +/- 0.6 to 9.3 +/- 0.4 (p = 0.003) with rosuvastatin being slightly better than atorvastatin. The inhibition of ROCK activity by statins did not correlate with reductions in LDL (p = 0.57) but was associated with improvement in FMD. In conclusion, these findings provide direct clinical evidence that statins, at clinically relevant doses, could differentially inhibit ROCK activity and improve endothelial function by cholesterol-independent mechanism.

BACKGROUND: Personal digital assistants (PDA) offer putative advantages over paper for collecting research data. However, there are no data prospectively comparing PDA and paper in the emergency department. The aim of this study was to prospectively compare the performance of PDA and paper enrollment instruments with respect to time required and errors generated. METHODS: We randomized consecutive patients enrolled in an ongoing prospective study to having their data recorded either on a PDA or a paper data collection instrument. For each method, we recorded the total time required for enrollment, and the time required for manual transcription (paper) onto a computer database. We compared data error rates by examining missing data, nonsensical data, and errors made during the transcription of paper forms. Statistical comparisons were performed by Kruskal-Wallis and Poisson regression analyses for time and errors, respectively. RESULTS: We enrolled 68 patients (37 PDA, 31 paper). Two of 31 paper forms were not available for analysis. Total data gathering times, inclusive of transcription, were significantly less for PDA (6:13 min per patient) compared to paper (9:12 min per patient; p < 0.001). There were a total of 0.9 missing and nonsense errors per paper form compared to 0.2 errors per PDA form (p < 0.001). An additional 0.7 errors per paper form were generated during transcription. In total, there were 1.6 errors per paper form and 0.2 errors per PDA form (p < 0.001). CONCLUSION: Using a PDA-based data collection instrument for clinical research reduces the time required for data gathering and significantly improves data integrity.

Lead identification by high-throughput screening of large compound libraries has been supplemented with virtual screening and focused compound libraries. To complement existing approaches for lead identification at Biogen Idec, a kinase-focused compound collection was designed, developed and validated. Two strategies were adopted to populate the compound collection: a ligand shape-based virtual screening and a receptor-based approach (structural interaction fingerprint). Compounds selected with the two approaches were cherry-picked from an existing high-throughput screening compound library, ordered from suppliers and supplemented with specific medicinal compounds from internal programs. Promising hits and leads have been generated from the kinase-focused compound collection against multiple kinase targets. The principle of the collection design and screening strategy was validated and the use of the kinase-focused compound collection for lead identification has been added to existing strategies.

The authors assess the equivalence of 2 assays and put forward a general approach for assay agreement analysis that can be applied during drug discovery. Data sets generated by different assays are routinely compared to each other during the process of drug discovery. For a given target, the assays used for high-throughput screening and structure-activity relationship studies will most likely differ in their assay reagents, assay conditions, and/or detection technology, which makes the interpretation of data between assays difficult, particularly as most assays are used to measure quantitative changes in compound potency against the target. To better quantify the relationship of data sets from different assays for the same target, the authors evaluated the agreement between results generated by 2 different assays that measure the activity of compounds against the same protein, ALK5. The authors show that the agreement between data sets can be quantified using correlation and Bland-Altman plots, and the precision of the assays can be used to define the expectations of agreement between 2 assays. They propose a scheme for addressing issues of assay data equivalence, which can be applied to address questions of how data sets compare during the lead identification and lead optimization processes in which assays are frequently added and changed.
