Abstract Background and study aims No standard procedure for endoscopic retrograde cholangiopancreatography is available for patients with Roux-en-Y hepaticojejunostomy (RYHJ) with side-to-end hepaticojejunostomy. We therefore explored methods of efficient scope insertion at a hepaticojejunostomy site. Patients and methods Patients with suspected biliary disease were prospectively enrolled. Based on two fluoroscopic images obtained on scope insertion into each lumen of a two-pronged Roux-en-Y anastomosis, we selected the lumen in which the distal end of the scope progressed toward the patient’s liver or head. The accuracy of this method for selecting the correct lumen leading to the hepaticojejunostomy site was investigated. Results Of the 33 included patients, successful insertion to the hepaticojejunostomy site was achieved in 32 (97 %), 26 (81 %) of whom had undergone the imaging method. The accuracy of the method was 88 % (23/26). The time required for insertion between the anastomotic site and the hepaticojejunostomy site was shorter when the lumen selection had been correct (13 minutes [7 – 30] (n = 23) vs. 18 minutes [8 – 28] (n = 9); P = 0.95). Conclusion This method based on two fluoroscopic images was useful for achieving efficient scope insertion in patients with RYHJ.Trial registered at University Hospital Medical Information Network Clinical Trials Registry (UMIN000014183).

Abstract We describe a discrete automated radioimmunoassay system for determining choriomammotropin (placental lactogen) in human serum. With the present system it can be measured in as many as 37 unknown sera (50 muL) and three quality-control sera, in duplicate, within 1.5 h. The time required for sample preparation, incubation (15 min), and separation of free and bound radioactivities (a 150 mL/L polyethylene glycol solution is superior to a twofold volume of absolute ethanol) is less than 45 min. The remaining time required is for counting and data processing. Intra-assay precision is 4.6% (CV). The modular approach endows the instrumentation with much flexibility, and consequently is suitable for automation of a wide range of assay protocols.

Background Quality-assured medicines are a principal means of achieving health-related Sustainable Development Goals. An example of quality assurance/quality control (QA/QC) procedures in drug procurement is provided by the operation of the Global Drug Facility (GDF) of the Stop TB Partnership, the largest provider of tuberculosis (TB) medicines to the public sector worldwide. Methods Procedures and results of GDF’s quality assurance/quality control (QA/QC) over the five-year period 2013–2017 were analysed retrospectively. 13,999 batches of 51 different medicines had been procured and reviewed within this period. 1,388 of these batches had been analysed in the laboratories of GDF’s external quality control agent (QCA). Assay and dissolution results determined by the manufacturers and by the external QCA were compared using Bland-Altman analysis. Results All investigated batches of medicines were in specifications at the time of shipment. The costs for QA/QC were 0.8% of purchase costs. The median time required for chemical analysis was 10 working days. Comparison of the medicine quality analysis results showed for the poorly water-soluble compound rifampicin a bias of 4.4%, with the manufacturers reporting higher values than the external QCA, most likely due to different methods employed for the analysis. Overall 95% limits of agreement (LOAs) were -6.7 to +8.0% for assay, and -10.1 to +11.8% for dissolution. In case of kanamycin injections, 95% LOAs for assay reached -14.5 to +13.2%, largely attributable to samples from one manufacturer who had used a microbiological assay while the external QCA had used an HPLC assay. Conclusions GDF’s procedures represent a useful benchmark when evaluating QA/QC procedures of other medicine procurement operations. Inter-laboratory comparison using Bland-Altman plots allows to investigate bias and variability in medicine quality control and should be considered as a routine procedure by drug procurement agencies, to identify priorities for further improvements.

Drug repositioning is a drug discovery strategy in which an existing drug is utilized as a therapeutic agent for a different disease. As information regarding the safety, pharmacokinetics, and formulation of existing drugs is already available, the cost and time required for drug development is reduced. Conventional drug repositioning has been dominated by a method involving the search for candidate drugs that act on the target molecules of an organism in a diseased state through basic research. However, recently, information hosted on medical information and life science databases have been used in translational research to bridge the gap between basic research in drug repositioning and clinical application. Here, we review an example of drug repositioning wherein candidate drugs were found and their mechanisms of action against a novel therapeutic target were identified via a basic research method that combines the findings retrieved from various medical and life science databases.

SummaryTo study the effect of computerized medical records on the efficiency of providers and the quality of care, 245 patient visits were randomly assigned to manual (134 visits) or computerized (111 visits) records during the implementation of a comprehensive medical information system, TMR, in the renal clinic of the Durham VA Medical Center. Data were collected on the time required for the providers to perform their various functions in the clinic. With the exception of prescription writing, the computerized records resulted in significant reductions in the time required for the physicians to obtain data from and enter data into the record (p <0.01). A similar time reduction was noted for the nursing pre-interview (p <0.001) when the computerized records were employed. With the inclusion of the time required for clerical computer data entry, no overall difference in person hours per visit was noted. The clinician’s utilization of the recorded data was significantly better (p <0.001) for the computerized records. Significant reductions in medication errors were also noted (p <0.01).

Human sperm assay (HSA) is a preferred in house quality control and proficiency test (PT) practiced in fertility laboratories. HSA is performed over varying durations, apparently without following set criteria. To better understand the assay time required for reprotoxicity testing in embryo culture media, we compared American-Association-of-Bioanalysts-(AAB-) administered HSA data to our own assay performed using PT samples obtained from AAB. Participating laboratories were required to culture sperm for 48 hours to determine media acceptability. Conclusions drawn from 48- and 24-hour observations were the same, suggesting that HSA could identify reprotoxic media in less time than required by AAB. Our assay revealed that changes in motility grade in adulterated media are significantly different from those in control media. Furthermore, grade changes can be identified earlier than differences in motility loss between samples. Analyzing motility and motility quality together provides a method for establishing an optimal time for HSA.

AbstractA method to determine the free burning rate of cigarettes is described. After conditioning the cigarettes are ignited one by one with an electrical heating device and then placed, in vertical position, in boxes of sheet metal and with sliding glass windows. Thus each cigarette is protected from draughts or from heat given off by adjacent cigarettes. A system of holes in the bottom and cover of the boxes permits the necessary air renewal. The time required for the free burning of a given length is determined visually with the aid of a stopwatch. The result of the test is expressed as the weight of tobacco burned per minute and per cigarette. As indicated by results presented in the paper, the method is suited for quality control work involving machine made cigarettes, as well as for the evaluation of different tobacco samples or cigarette papers. If certain precautions are met, the test can also be applied to hand-made cigarettes. The free burning rate was found to be largely determined by the kind of paper and the type of tobacco used. On the other hand, no decisive influence of the arrangement of the tobacco shreds within the cigarette could be observed as long as normally filled cigarettes were used for the tests

EHR play an important role in the health care system, so the issue of data efficiency is key in the development of the EHR system. One of the key benefits of EHR is an access to medical information anywhere, anytime. While testing this advantage, it was found that it is performed only privately and does not take into account the dynamics of patients. Therefore, a model for calculating the efficiency of EHR on the basis of full coverage was developed. The study presents a model of the “Element” system, which provides for maximization of the coverage ratio of EHR to provide providers with access to medical records in the form required. The Element system is based on medical information packaging methods such as the dictionary method, the direct matching method and the combined method, and also allows healthcare professionals to be available to users’ medical information in this regard when EHR with customer data arises from EHR medical fund. In this case, if the presented system can be reduced both the time of work with medical documents and the time required for the appointment of drugs, which, accordingly, reduces the time to receive medical care. A set-theoretical model of the information system for improving the quality of medical services is proposed. The study of this model showed the need to measure the effectiveness of medical systems, taking into account their coverage. Medstar, Medkit and Helsi systems, which are part of the eHealth system, were used for the analysis. During the study, such concepts as full and partial coverage of systems were identified, the disadvantages of partial coverage were indicated. It has been found that for maximum efficiency it is necessary to minimize the time required to access medical information, which is achieved through full coverage.
