Abstract

Compared to contact fingerprint images, contactless fingerprint images exhibit four distinct characteristics: (1) they contain less noise; (2) they have fewer discontinuities in ridge patterns; (3) the ridge-valley pattern is less distinct; and (4) they pose an interoperability problem, as they lack the elastic deformation caused by pressing the finger against the capture device. These properties present significant challenges for the enhancement of contactless fingerprint images. In this study, we propose a novel contactless fingerprint identification solution that enhances the accuracy of minutiae detection through improved frequency estimation and a new region-quality-based minutia extraction algorithm. In addition, we introduce an efficient and highly accurate minutiae-based encoding and matching algorithm. We validate the effectiveness of our approach through extensive experimental testing. Our method achieves a minimum Equal Error Rate (EER) of 2.84\% on the PolyU contactless fingerprint dataset, demonstrating its superior performance compared to existing state-of-the-art techniques. The proposed fingerprint identification method exhibits notable precision and resilience, proving to be an effective and feasible solution for contactless fingerprint-based identification systems.

Abstract

Green nanoparticles (GNPs) are being produced from microbial and plant sources and have numerous applications in various fields. The article focuses on the NPs that provide various focal points in the many scientific and technological fields for the cutting-edge uses of nanoparticles. Due to their toxicity, cost-effectiveness, ease of use, and environmental friendliness, green NPs are extremely important. It is closely observed how important green NPs are to the development of science and technology in the context of sustainable therapeutics. The only issue with green nanoparticles is occasionally how toxic they can be. A sustainable future, which the entire world looks forward to, is directly related to green nanoparticles and their role in numerous applications.

Abstract

Background: Anagrelide is a drug used for treatment of essential thrombocytosis especially when conventional therapy is insufficient. Adverse effects associated with anagrelide are palpitation, liver toxicity, renal failure and in few cases pericardial effusion. We here report a rare case of anagrelide induced pericardial effusion. Case Presentation: A 76-year-old male with past medical history of hypertension, hyperlipidemia, chronic obstructive pulmonary disease, and myeloproliferative disorder presented to the emergency department with dyspnea on rest and exertion. He was initially treated with hydroxyurea for thrombocytosis but was later switched to anagrelide. On examination patient had muffled heart sounds. Lab investigations identified hyperkalemia and transaminitis. Transthoracic echocardiogram identified a moderate sized pericardial effusion. The pericardial effusion and transaminitis were attributed to anagrelide toxicity as other causes were ruled out. Pericardiocentesis was performed and anagrelide was discontinued. Patient was discharged in a well-compensated state with outpatient follow-up in two to three weeks. Conclusion: Anagrelide is considered to be very effective treatment for essential thrombocytosis. It is, however, associated with serious adverse effects such as pericardial effusion, liver toxicity and palpitations. The mechanisms of these adverse drug reactions are still not completely understood. We suggest that patient taking anagrelide presenting with shortness of breath should have a transthoracic echocardiogram performed to rule out pericardial effusion. Liver enzymes should also be monitored closely and anagrelide discontinued immediately if the above-mentioned adverse events are noted. [ABSTRACT FROM AUTHOR]

Abstract

Introduction:With advancement in cancer treatments, the life expectancy of oncology patients has improved. Therefore, transcatheter aortic valve replacement (TAVR) can now be considered as a feasible option for oncology patients with severe aortic stenosis (AS) to avoid adverse outcomes from valvular disease.Hypothesis:Short-term and long-term mortality is similar in cancer and non-cancer patients treated with TAVR for severe AS.Methods:MEDLINE, Pubmed, and Cochrane Central Register of Controlled Trials were searched from inception of the respective database through May 2019. Patients with cancer who underwent treatment with TAVR for severe AS were included and compared to identical population but without cancer. Studies that used surgical aortic valve replacement (SAVR) as treatment for AS were excluded. Primary endpoint was short-term and long-term mortality.Results:Of 890 studies identified, 5 studies met inclusion criteria. 3 studies analyzed short-term mortality and showed no significant difference in patients treated with TAVR with and without cancer (RR, 0.63; 95% CI, 0.35-1.14; P=0.12) (Figure 1). In contrast, 5 studies analyzed long-term mortality and identified that cancer patients had significantly higher long-term mortality after treatment with TAVR when compared to patients without cancer (RR, 1.77; 95% CI, 1.35-2.31; P=<0.0001) (Figure 2).Conclusions:Patients with cancer and severe AS have higher long-term mortality after TAVR while having relatively similar short-term mortality when compared to patients without cancer. The decision to perform TAVR in cancer patients should be individualized based on life expectancy and co-morbidities.
