Multipronged strategy for protection and motivation of healthcare workers during the COVID-19 pandemic: a real-life study.

Objective: We aimed to assess risk of COVID-19 infection & seroprotection status in healthcare workers (HCWs) in both hospital and community settings following an intensive vaccination drive in India.

Setting: Tertiary Care Hospital.

Methods: We surveyed COVID-19 exposure risk, personal protective equipment (PPE) compliance, vaccination status, mental health & COVID-19 infection rate across different HCW cadres.

Evaluating platelet concentrates by platelet indices, thromboelastography, and flow cytometry.

Introduction: Platelet transfusion has been therapeutically used in patients with thrombocytopenia and platelet function defects over the years. The use of advanced techniques may add value in assessing the quality of platelet products. The aim of the study was to assess stored platelet concentrates (PCs) prepared in blood banks for platelet indices, clot strength, and platelet function.

Investigating Endocrine Causes in Fluid Non-responsive Hypotension: An Interesting Case of a Pituitary Macroadenoma.

In this case, the message is conveyed that after ruling out sinister causes of hypotension, endocrine causes should also be considered, particularly in the light of a relatively long history, absence of any sepsis and organ dysfunction, preserved urine output, euvolemic status, and with no significant response to intravenous fluid. In our case, a patient with hypotension with relatively stable other clinical parameters has been evaluated to reveal pituitary macroadenoma as an underlying diagnosis.

Neuron-derived extracellular vesicles as a liquid biopsy for brain insulin dysregulation in Alzheimer's disease and related disorders.

Extracellular vesicles (EVs) have emerged as novel blood-based biomarkers for various pathologies. The development of methods to enrich cell-specific EVs from biofluids has enabled us to monitor difficult-to-access organs, such as the brain, in real time without disrupting their function, thus serving as liquid biopsy. Burgeoning evidence indicates that the contents of neuron-derived EVs (NDEs) in blood reveal dynamic alterations that occur during neurodegenerative pathogenesis, including Alzheimer's disease (AD), reflecting a disease-specific molecular signature.

Anomalous pumping in the non-Hermitian Rice-Mele model.

We study topological charge pumping (TCP) in the Rice-Mele (RM) model with irreciprocal hopping. The non-Hermiticity gives rise to interesting pumping physics, owing to the presence of skin effect and exceptional points. In the static one-dimensional (1D) RM model, we find two independent tuning knobs that can drive the topological transition, namely, non-Hermitian parameter $\gamma$ and system size $N$.
