Community palliative care clinical nurse specialists as independent prescribers: part 2.

This study explored the lived experiences of clinical nurse specialists who can prescribe independently in their role of providing support to patients with palliative care needs within the community. Part 1 of this study examined how the study was carried out; this second part explores the findings. The nurses reported that being able to prescribe enabled them to provide seamless, holistic care, which gave patients faster access to medicines, especially at weekends when their GP was unavailable. Prompt availability of medicines led to effective symptom control and consequently a better quality of life for patients. The main barrier to prescribing was difficulty in accessing patient records. Independent prescribing by community nurse specialists is beneficial for patients receiving palliative care and their families while they are being cared for at home, and provides job satisfaction for the nurses.

Community palliative care clinical nurse specialists as independent prescribers: part 1.

The Department of Health and Social Care has recently reiterated its commitment to improvement in the quality of end-of-life care and emphasised the importance of all patients having rapid access to medication. The aim of this study was to explore the lived experiences of clinical nurse specialists who are able to prescribe independently in their role in providing support for patients with palliative care needs within the community setting. Interpretive phenomenology was employed in order to understand and interpret the experiences of six nurse independent prescribers employed as community palliative care clinical nurse specialists. This purposive sampling was preferred with semi-structured interviews as the most appropriate data collection technique. This is the first of a two-part article. In this part, the authors describe how the study was undertaken. Part 2 will provide the results, outline the key themes that were extracted from the study, and discuss them. It will be published in the next issue of the Journal.

MicroSEQ Salmonella spp. Detection Kit using the Pathatrix 10-Pooling Salmonella spp. Kit linked protocol method modification. Performance Tested Method 031001.

Real-time PCR methods for detecting foodborne pathogens offer the advantages of simplicity and quick time to results compared to traditional culture methods. The addition of a recirculating pooled immunomagnetic separation method prior to real-time PCR analysis increases processing output while reducing both cost and labor. This AOAC Research Institute method modification study validates the MicroSEQ Salmonella spp. Detection Kit [AOAC Performance Tested Method (PTM) 031001] linked with the Pathatrix 10-Pooling Salmonella spp. Kit (AOAC PTM 090203C) in diced tomatoes, chocolate, and deli ham. The Pathatrix 10-Pooling protocol represents a method modification of the enrichment portion of the MicroSEQ Salmonella spp. protocol. The results of the method modification were compared to standard cultural reference methods for diced tomatoes, chocolate, and deli ham. All three matrixes were analyzed in a paired study design. An additional set of chocolate test portions was analyzed using an alternative enrichment medium in an unpaired study design. For all matrixes tested, there were no statistically significant differences in the number of positive test portions detected by the modified candidate method compared to the appropriate reference method. The MicroSEQ Salmonella spp. protocol linked with the Pathatrix individual or 10-Pooling procedure demonstrated reliability as a rapid, simplified, method for the preparation of samples and subsequent detection of Salmonella in diced tomatoes, chocolate, and deli ham.

LNA incorporated siRNAs exhibit lower off-target effects compared to 2'-OMethoxy in cell phenotypic assays and microarray analysis.

Despite the promise of short interfering RNAs (siRNA), contending with off-target is a challenge for RNAi users. To alleviate these problems, we have developed locked nucleic acid (LNA) modified siRNAs and optimized performance using cellular phenotypic assays as well as microarray analysis. During development, we compared LNA and 2'OMethoxy (2'OMe) chemistries placed strategically throughout the siRNA molecule and found a novel pattern of LNA placement that greatly improved the specificity of the siRNA and reduced it's toxicity in culture while preserving the potency of the siRNA. The improvements in specificity made by LNA-modified siRNAs were developed and validated by measuring the phenotypic signatures in a high content cell-based screening assay as well as comparison of the level of differentially expressed genes observed in microarray analysis between modified and unmodified siRNAs. HT screening of a collection of genes demonstrated that the LNA-modified siRNAs exhibits the best overall rate to elicit the expected phenotype, reduced toxicity and achieved an improved coherence of phenotype compared to 2'OMe-modified or unmodified siRNAs.
