OBJECTIVE: This study aims to evaluate the cost effectiveness of genetic and genomic testing strategies for the diagnosis of rare developmental disorders in NHS Scotland.
METHODS: Six genetic and genomic testing strategies were evaluated using a decision tree model. First-line, second-line and last-resort trio genome sequencing (GS), and second-line and last-resort trio exome sequencing (ES) were compared with standard genetic testing. The cost effectiveness of each strategy was expressed in terms of incremental cost per additional diagnosis. The impact of uncertainty on cost-effectiveness results was explored using deterministic and probabilistic sensitivity analysis.
RESULTS: 2nd-line ES was a cost-saving option, increasing diagnostic yield by 13.9% and decreasing cost by £1027 per trio compared to standard genetic testing. Compared to ES, strategies involving GS increased costs significantly, with only a moderate or zero improvement in diagnostic yield. Sensitivity analysis indicated that significant reductions in cost or improvements in diagnostic yield are required before 1st-line GS becomes cost effective.
CONCLUSIONS: 2nd-line ES (after chromosomal microarray; replacing gene panel testing) for the diagnosis of developmental disorders is a cost-saving option for the Scottish NHS. Ongoing economic evaluation is required to monitor the evolving cost and diagnostic yield of GS and ES over time.

UNASSIGNED: Apply established principles of evidence-based medicine to the interpretation of the cost-effectiveness analysis related to the MINT Randomized Clinical Trials (RCTs).
UNASSIGNED: Editorial.
UNASSIGNED: Spine Intervention Society\'s guidelines for assessing studies on the treatment of pain were applied to a published cost-effectiveness analysis of radiofrequency denervation data from the MINT RCTs.
UNASSIGNED: Application of evidence-based medicine principles reveals the MINT RCTs\' major deficiencies in patient selection, diagnostic paradigm, radiofrequency neurotomy technique, co-interventions, outcome measurement, power analysis study sample characteristics, data analysis, and loss to follow-up; which marginalizes the generalizability and conclusions of the cost-effectiveness analysis.
UNASSIGNED: The cost analysis performed in \"Cost-Effectiveness of Radiofrequency Denervation for Patients With Chronic Low Back Pain: The MINT Randomized Clinical Trials\" is based on the MINT RCTs results. The MINT RCTs significant metholodological design flaws, lead to issues in validty for the subsequent cost-effectiveness analysis. Application of the cost-effective analysis to patient care paradigms should be limited given the concerns with validity.

Dog bites account for 250,000 attendances for urgent and emergency care each year. They pose risks including infections with potentially life-threatening complications. This article scrutinises the evidence underpinning the use of prophylactic antibiotics in dog bite wounds. A focused literature review involving four databases specialising in peer-reviewed healthcare literature was conducted to identify the highest quality evidence, which was then systematically appraised. The use of antibiotics in treating dog bite wounds to reduce the risk of infection is largely supported by the evidence. However, significant limitations exist in the research, with patient-specific criteria for administering prophylactic antibiotics and the associated risks and financial costs not addressed. Further research into antibiotic treatment for dog bites would help to support clinicians, nurse practitioners and the wider nursing and allied health professional team in urgent and emergency care by informing safe practice and in turn improving patient care, cost-effectiveness and antimicrobial stewardship.

BACKGROUND: Evidence on the cost effectiveness of deprescribing in multimorbidity is limited.
OBJECTIVE: To investigate the cost effectiveness of a general practitioner (GP) delivered, individualised medication review to reduce polypharmacy and potentially inappropriate prescribing in older patients with multimorbidity in Irish primary care.
METHODS: Within trial economic evaluation, from a healthcare perspective and based on a cluster randomised controlled trial with a 6 month follow up and 403 patients (208 Intervention and 195 Control) recruited between April 2017 and December 2019. Intervention GPs used the SPPiRE website which contained educational materials and a template to support a web-based individualised medication review. Control GPs delivered usual care. Incremental costs, quality adjusted life years (QALYs) generated using the EQ-5D-5L instrument, and expected cost effectiveness were estimated using multilevel modelling and multiple imputation techniques. Uncertainty was explored using parametric, deterministic and probabilistic methods.
RESULTS: On average, the SPPiRE intervention was dominant over usual care, with non-statistically significant mean cost savings of €410 (95% confidence interval (CI): - 2211, 1409) and mean health gains of 0.014 QALYs (95% CI - 0.011, 0.039). At cost effectiveness threshold values of €20,000 and €45,000 per QALY, the probability of SPPiRE being cost effective was 0.993 and 0.988. Results were sensitive to missing data and data collection period.
CONCLUSIONS: The study observed a pattern towards dominance for the SPPiRE intervention, with high expected cost effectiveness. Notably, observed differences in costs and outcomes were consistent with chance, and missing data and related uncertainty was non trivial. The cost effectiveness evidence may be considered promising but equivocal.

Objectives: The current study evaluated the efficacy of iliac and IVC ultrasound alone for follow-up evaluation of iliac vein stents in patients with pelvic venous disorders or iliac occlusion from chronic deep vein thrombosis. Methods: A retrospective single site cohort study was conducted by evaluating the most recent 100 iliac vein and inferior vena cava ultrasounds in patients who had undergone iliac vein stenting. Inclusion criteria included a history of iliac vein stent placement. Exclusion criteria included patients under 18-years-old, duplicates of the same patient, and pregnancy at the time of ultrasound. The degree of visualization for color flow, gray scale, and phasicity were determined and classified into the following categories: complete, partial, or none. In addition, each chart was assessed for external compression, in-stent narrowing, and requirements for further imaging. Results: Of the 100 iliac vein and IVC ultrasounds assessed in this review, 99 of the ultrasounds were sufficient for evaluation during follow-up visits without requiring further investigation. Within this study cohort, the average follow-up time was 22 months. The average participant body mass index was 27.6. One iliac vein and IVC ultrasound was considered inadequate for follow-up evaluation and required further imaging. Conclusion: The use of iliac and IVC venous doppler ultrasound alone in the follow-up evaluation of iliac stent patency is effective and noninvasive and avoids unnecessary radiation exposure and cost.

OBJECTIVE: The purpose of this study was to evaluate the accuracy and cost-effectiveness of the dental models 3D printed in vertical and horizontal orientation as compared to the conventional plaster and digital models.
METHODS: This study involved scanning 50 plaster models using Maestro 3D Desktop Scanner (AGE Solutions, Pisa, Italy). The STL file obtained from the scanner was processed and three-dimensionally (3D) printed in the horizontal and vertical orientation using a PolyJet 3D printer (Objet 30 prime, Stratasys Ltd., Eden Prairie, Minnesota, United States). The accuracy of the rapid-prototyped (3D printed) models was measured from the pre-determined landmarks and was compared among the groups. In addition, determining the cost-effectiveness of the 3D printed models in different orientations was based on the amount of material (resin) utilized during the 3D printing process. ANOVA was used to determine the accuracy of the models.
RESULTS: There were statistically insignificant differences (P>0.05) among rapid-prototyped models (≤0.06mm) compared to plaster models and digital models for the linear measurements made in all three planes of space. The dental models printed in the horizontal orientation were found to be more cost-effective than those printed in a vertical orientation in terms of the amount of material (resin) utilized and printing time during the 3D printing process.
CONCLUSIONS: The accuracy of rapid-prototyped models 3D printed in the horizontal and vertical orientations was comparable to the plaster models and digital models for clinical applications. Horizontally printed models were more cost-effective than vertically printed models.

The work in this paper incorporated printed circuit board (PCB) technology into micro-direct methanol fuel cells (µDMFCs) and conjectured and verified the performance degradation factors of PCB current collectors in µDMFCs by testing different designed configuration µDMFCs. The experiment results showed that all kinds of PCB coating can benefit from the porous stainless-steel plates covering to a great extent. At the end of 48 h discharging, µDMFCs with porous stainless-steel plates between MEA and PCB coating achieved higher performance than those of the direct contacting series. It can be inferred from various types of experimental data that because of stainless-steel porous plate isolating, the impact of corrosion on the surface of the PCB electrode plate was reduced to a certain extent. The corrosion of the electrode plate was slowed down in the µDMFC discharging as a result of the passivation behavior on the iron surface and a decrease in corrosion current. Consequently, the attenuation of the PCB performance was delayed. The conclusion of this work explores a practical direction to enhance the cost-effectiveness of fuel cells, promoting the large-scale application of DMFCs in the future.

When the goal is to help patients improve their quality of life, it makes sense to focus directly on the activities and relationships that are most important to each patient. This can be accomplished most effectively by following a three-step process that includes 1) connecting with the patient around what matters to them, 2) co-creating a goal-oriented plan, and 3) collaborating with patient, family, team members, and consultants to increase the probability of success. Once this approach has been mastered and the necessary systems, processes, and relationships are in place, this should not take more time than a problem-oriented approach, and it will almost certainly be more satisfying for both physician and patient. The impact on population-based quality metrics is uncertain. Though fewer patients may choose to follow standard recommendations, those who do may be more likely to adhere to them.
