Cleaning validation for blister packaging machines in hospital-supplying pharmacies.

Objective: To ensure quality-assured care for patients, validation of a cleaning process for blister machines is essential. Due to the high operating costs of maintaining high-performance liquid chromatography (HPLC) which is mainly used for this type of analysis, a new, quick and cost-effective analysis method using UV-Vis spectroscopy has been developed.

Method: Marker substances (metamizole (dipyrone) and paracetamol tablets) were packed in blisters.

Introduction of Unit-Dose Care in the 1,125 Bed Teaching Hospital: Practical Experience and Time Saving on Wards.

Purpose: The shortage of nursing staff as well as the slow progress in the German health care system's digitalisation has gained much attention due to COVID-19. Patient-specific medication management using the unit-dose dispensing system (UDDS) has the potential for a lasting and positive influence on both digitalisation and the relief of nursing staff.

Methods: Nursing staff UDDS-acceptance was determined via a validated online survey.

We Ask and Listen: A Group-Wide Retrospective Survey on Satisfaction with Digital Medication Software.

Purpose: Computerized physician order entry (CPOE) and clinical decision support systems (CDSS) are used internationally since the 1980s. These systems reduce costs, enhance drug therapy safety, and improve quality of care. A few years ago, there was a growing effort to digitize the healthcare sector in Germany.

Enzymatically hydrolyzed low-density lipoprotein modulates inflammatory responses in endothelial cells.

There is evidence that low-density lipoprotein (LDL) is modified by hydrolytic enzymes, and that the product (E-LDL) induces selective production of interleukin 8 (IL-8) in endothelial cells. Since nuclear factor-kappaB (NF-kappaB) is a major regulator of IL-8 transcription, we studied its activation in endothelial cells treated with E-LDL. Unexpectedly, the modified lipoprotein not only failed to activate NF-kappaB, but completely blocked its activation by tumour necrosis factor-alpha (TNF-alpha) in EA.

Enzymatically modified LDL induces cathepsin H in human monocytes: potential relevance in early atherogenesis.

Objective: Modification with proteases and cholesterylesterase transforms LDL to a moiety that resembles lipoproteins isolated from atherosclerotic lesions and possesses atherogenic properties. To identify changes in monocyte-derived foam cells laden with enzymatically modified LDL (E-LDL), we compared patterns of the most abundant transcripts in these cells after incubation with LDL or E-LDL.

Methods And Results: Serial analyses of gene expression (SAGE) libraries were constructed from human monocytes after treatment with LDL or E-LDL.

Enzymatically modified nonoxidized low-density lipoprotein induces interleukin-8 in human endothelial cells: role of free fatty acids.

Background: Treatment of low-density lipoprotein (LDL) with a protease and cholesterolesterase transforms the lipoprotein to an entity that resembles lipoprotein particles in atherosclerotic lesions, which have a high content of free cholesterol, reflecting extensive de-esterification in the intima. Because de-esterification would occur beneath the endothelium, we examined the effects of enzymatically modified LDL (E-LDL) on cultured endothelial cells.

Methods And Results: Incubation of endothelial cells with E-LDL provoked selective accumulation of interleukin (IL)-8 mRNA and production of the cytokine.

Resealing of large transmembrane pores produced by streptolysin O in nucleated cells is accompanied by NF-kappaB activation and downstream events.

Streptolysin O (SLO), archetype of a cholesterol-binding bacterial cytolysin, forms large pores in the plasma membrane of mammalian cells. We have recently reported that when a limited number of pores are generated in a cell, they can be sealed in a Ca++-dependent process. Here, we show that resealing is followed by the release of IL-6 and IL-8 from keratinocytes and from endothelial cells, both relevant targets for SLO attack.
