The paper is a mini review on the authors own work related to laser induced processes at metal nanoparticle/oxidic support systems. A number of aspects will be addressed ranging from the nano particle size dependence on the efficiency of the photochemical process, the influence of low coordination sites of the nano particles and dynamical processes such as energy transfer between adsorbates, light induced particle changes or spill over processes. The paper reviews nano and femtosecond laser experiments as well as quantum state resolved experiments. Results will be compared to typical findings from simple oxidic supports and metal single crystals. This review may be of interest for future photocatalyst development for applications such as solar fuel synthesis and related problems. [ABSTRACT FROM AUTHOR]

Strongyloides stercoralis is an important human parasite, especially in rural areas and developing countries. Infected immunosuppressed patients are at risk for hyperinfection, with severe clinical consequences. Here we describe the incidental detection and diagnosis of an unexpected S. stercoralis infection by methods designed to detect fungal 28S ribosomal DNA. [ABSTRACT FROM AUTHOR]

Neurocysticercosis is caused by Taenia solium infection of the brain. Diagnosis is most often made by visualization of the parasitic scolex by magnetic resonance imaging of the brain or by characteristic neuroimaging findings with serologic test results positive for T. solium. A patient who presents with a solitary brain lesion usually poses a diagnostic dilemma, because the differential diagnosis often includes neurocysticercosis and other infections or neoplasm. Although the sensitivity of serologic testing for T. solium approaches 100% in patients with multiple intraparenchymal cysts, the sensitivity of testing for patients with solitary cysts is <50%, which makes serologic testing a less useful diagnostic tool for patients with solitary central nervous system (CNS) lesions. We describe 2 patients with solitary CNS lesions who received a neurocysticercosis diagnosis after identification of T. solium DNA in brain biopsy tissue with use of a global DNA screening platform. Global screening is a promising tool for the diagnosis of CNS infection, especially when traditional diagnostic tools are insensitive. [ABSTRACT FROM AUTHOR]

Abstract: The adsorption of CO on well-defined Co–Pt alloy surfaces prepared by physical vapour deposition in ultra-high vacuum was studied by Fourier transform infrared reflection absorption spectroscopy (FT-IRRAS) and temperature-programmed desorption (TPD) spectroscopy. The adsorption behaviour was found to depend strongly on the composition of the surface and the first subsurface atomic layer. In the case of low Co concentrations at the surface CO adsorbs preferentially on Pt sites, however with an enthalpy of adsorption which is substantially lowered when compared to CO adsorption on Pt single crystals. TPD shifts of ∼60K were found. When Co dominates the surface composition, CO adsorbs preferentially on Co sites, however with an enthalpy of adsorption leading to a TPD shift by ∼80K to higher temperatures with respect to monometallic single crystals. This behaviour can be explained by ligand effects, i.e., by an electronic influence of the presence of a second metal in the chemical environment of a given adsorption center. The experimental findings were compared with theoretical calculations. [Copyright &y& Elsevier]

The aim of the present study was to analyse the effect of organic coating of titanium implants on periimplant bone formation and bone/implant contact. Three types of implants were used: (i) Ti6Al4V implants with polished surface (control 1) (ii) Ti6Al4V implants with collagen coating (control 2) (iii) Ti6Al4V implants with collagen coating and covalently bound RGD peptides. All implants had square cross-sections with an oblique diameter of 4.6 mm and were inserted press fit into trephine burr holes of 4.6 mm in the mandibles of 10 beagle dogs. The implants of five animals each were evaluated after a healing period of 1 month and 3 months, during which sequential fluorochrome labelling of bone formation was performed. Bone formation was evaluated by morphometric measurement of the newly formed bone around the implant and the percentage of implant bone contact. After 1 month there was only little bone/implant contact, varying between 2.6 and 6.7% in the cortical bone and 4.4 and 5.7% in the cancellous bone, with no significant differences between the three types of implants. After 3 months, implants with polished surfaces exhibited 26.5 and 31.2% contact in the cortical and cancellous bone, respectively, while collagen-coated implants had 19.5 and 28.4% bone contact in these areas. Implants with RGD coating showed the highest values with 42.1% and 49.7%, respectively. Differences between the surface types as such were not significant, but the increase in bone/implant contact from 1 to 3 months postoperatively was significant only in the group of RGD-coated implants (P = 0.008 and P = 0.000). The results of this pilot study thus provide only weak evidence that coating of titanium implants with RGD peptides in the present form and dosage may increase periimplant bone formation in the alveolar process. The results therefore require further verification in a modified experimental setting. [ABSTRACT FROM AUTHOR]

A 20-year-old male presented with multiple subcutaneous nodules on the head, neck, chest and oral cavity. FNA and biopsy showed pigmented fungal hyphae diagnostic of multifocal phaeohyphomycosis, found to be Exophiala spinifera by molecular diagnostics. The presentation initially raised concern for disseminated disease and occult immunosuppression. However, the patient appeared to be immunocompetent and otherwise healthy. Upon further inquiry, the patient was in a motor vehicle accident 4 years before presentation; he was ejected into a vegetable field resulting in multiple open wounds. Multifocal phaeohyphomycosis usually indicates disseminated systemic disease from immunosuppression and carries a grave prognosis. [ABSTRACT FROM AUTHOR]

Background: The implementation of computerised clinical decision support systems has the potential to enhance healthcare by improving patient safety, practitioner performance, and patient outcomes. Notwithstanding the numerous advantages, the uptake of clinical decision support systems remains constrained, thereby impeding the full realisation of their potential. To ensure the effective and successful implementation of these systems, it is essential to identify and analyse the reasons for their low uptake and adoption. This protocol outlines an umbrella review, which will synthesise the findings of existing literature reviews to generate a comprehensive overview of the barriers and facilitators to the implementation and adoption of decision support systems across healthcare settings., Methods: This umbrella review protocol was developed in accordance with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA-P) guidelines. Searches for eligible articles will be conducted in four electronic bibliographic databases, including PubMed/MEDLINE, IEEE Xplore, Scopus, and Web of Science. Obtained results will be independently screened by four reviewers based on pre-defined eligibility criteria. The risk of bias will be assessed for all eligible articles. Data on barriers and facilitators to the implementation and adoption of clinical decision support systems will be extracted, summarised, and further categorised into themes that aim to describe the originating environment or concept of the respective factor. The frequency of all identified barriers and facilitators within the group of included reviews will be determined in order to establish a prioritisation of the factors., Discussion: This umbrella review protocol presents a methodology for the systematic synthesis of barriers and facilitators to the implementation and adoption of clinical decision support systems across healthcare settings. The umbrella review will enable the development of novel implementation and adoption strategies that reinforce the identified facilitators and circumvent barriers, thereby promoting the use-oriented evaluation and effective utilisation of clinical decision support systems., Systematic Review Registration: PROSPERO CRD42024507614., Competing Interests: Declarations.

In recent years, artificial intelligence (AI) has gained momentum in many fields of daily live. In healthcare, AI can be used for diagnosing or predicting illnesses. However, explainable AI (XAI) is needed to ensure that users understand how the algorithm arrives at a decision. In our research project, machine learning methods are used for individual risk prediction of hospital-onset bacteremia (HOB). This paper presents a vision on a step-wise process for implementation and evaluation of user-centered XAI for risk prediction of HOB. An initial requirement analysis revealed first insights on the users' needs of explainability to use and trust such risk prediction applications. The findings were then used to propose step-wise process towards a user-centered evaluation.
