Objectives: Stroke is the second-leading cause of death and the third-leading cause of death and disability combined in the world. We need to find easy, available, and reliable parameters on which we can depend to prevent stroke, predict outcome, and determine prognosis. This will help in stroke management in the future. Materials and Methods: We noted blood counts and serum homocysteine levels in acute stroke patients after the exclusion of confounding factors. Our team recorded the detailed demographic and blood parameters (blood counts and homocysteine) of acute stroke patients who got admitted to different departments of our hospital in 5 months. We later correlated or tried to find the association between these parameters and stroke severity (NIHSS), other clinical parameters such as dysarthria and stroke outcome (Modified Rankin Score (mRS) at discharge and at 3 months). The team also tried to find relationships, if any, with different stroke subtypes as per the Trial of ORG 10172 in Acute Stroke Treatment classification. Results: Out of 100 patients (34 females and 66 males), we had 28 patients with hyperhomocysteinemia (HHcy). The high neutrophil count and total leukocyte count correlated with stroke severity, dysarthria, and outcome at 3 months (poor mRS). While, it was the opposite in the case of lymphocyte count. Homocysteine level did not correlate with stroke severity or outcome but with dyslipidemia. HHcy was more prevalent among patients with large artery atherosclerotic disease. Conclusion: Findings of our study were agreeable to earlier studies on the relationship between blood counts and stroke prognosis. Although high homocysteine level was associated with stroke, its level was not found to be related to stroke severity or outcome. However, further study with a larger sample size is required to draw a confident conclusion.

The fusion of non-Abelian anyons is a fundamental operation in measurement-only topological quantum computation 1 . In one-dimensional topological superconductors (1DTSs) 2-4 , fusion amounts to a determination of the shared fermion parity of Majorana zero modes (MZMs). Here we introduce a device architecture 5 that is compatible with future tests of fusion rules. We implement a single-shot interferometric measurement of fermion parity 6-11 in indium arsenide-aluminium heterostructures with a gate-defined superconducting nanowire 12-14 . The interferometer is formed by tunnel-coupling the proximitized nanowire to quantum dots. The nanowire causes a state-dependent shift of the quantum capacitance of these quantum dots of up to 1 fF. Our quantum-capacitance measurements show flux h/2e-periodic bimodality with a signal-to-noise ratio (SNR) of 1 in 3.6 μs at optimal flux values. From the time traces of the quantum-capacitance measurements, we extract a dwell time in the two associated states that is longer than 1 ms at in-plane magnetic fields of approximately 2 T. We discuss the interpretation of our measurements in terms of both topologically trivial and non-trivial origins. The large capacitance shift and long poisoning time enable a parity measurement with an assignment error probability of 1%., Competing Interests: Competing interests: The authors declare no competing interests., (© 2025.
