Background: Stroke is a leading cause of global mortality and disability, with a disproportionately high burden in low- and middle-income countries. Access to intravenous thrombolysis (IVT) and endovascular treatment (EVT) remains extremely limited.

Aims: We evaluated the spatial distribution and geographic accessibility of stroke centers in India.

MARTINI Coarse-Grained Force Field for Thermoplastic Starch Nanocomposites.

Thermoplastic starch (TPS) is an excellent film-forming material, and the addition of fillers, such as tetramethylammonium-montmorillonite (TMA-MMT) clay, has significantly expanded its use in packaging applications. We first used an all-atom (AA) simulation to predict several macroscopic (Young's modulus, glass transition temperature, density) and microscopic (conformation along 1-4 and 1-6 glycosidic linkages, composite morphology) properties of TPS melt and TPS-TMA-MMT composite. The interplay of polymer-surface (weakly repulsive), plasticizer-surface (attractive), and polymer-plasticizer (weakly attractive) interactions leads to conformational and dynamics properties distinct from those in systems with either attractive or repulsive polymer-surface interactions.

Patient, family caregiver, and economic outcomes of an integrated screening and novel stepped collaborative care intervention in the oncology setting in the USA (CARES): a randomised, parallel, phase 3 trial.

Background: The current standard of care of screening and referring patients for treatment for symptoms, such as depression, pain, and fatigue, is not effective. This trial aimed to test the efficacy of an integrated screening and novel stepped collaborative care intervention versus standard of care for patients with cancer and at least one of the following symptoms: depression, pain, or fatigue.

Methods: This randomised, parallel, phase 3 trial was conducted in 29 oncology outpatient clinics associated with the UPMC Hillman Cancer Center in the USA.

Free Energy Surface and Molecular Mechanism of Slow Structural Transitions in Lipid Bilayers.

Lipid membrane remodeling, crucial for many cellular processes, is governed by the coupling of membrane structure and shape fluctuations. Given the importance of the ∼ nm length scale, details of the transition intermediates for conformational change are not fully captured by a continuum-mechanical description. Slow dynamics and the lack of knowledge of reaction coordinates (RCs) for biasing methods pose a challenge for all-atom (AA) simulations.

Bispidine as a promising scaffold for designing molecular machines.

The development of artificial molecular machines is a challenging endeavor. Herein, we have synthesized a series of bispidine diamides D1-D6 that exhibit rotation reminiscent of a motor motion. Dynamic NMR, X-ray diffraction, quantum mechanical calculations, and molecular dynamics simulations provided insights into their rotational dynamics.

People's perceptions on COVID-19 vaccination: an analysis of twitter discourse from four countries.

More than six and half million people have died as a result of the COVID-19 pandemic till Dec 2022. Vaccination is the most effective means to prevent mortality and infection attributed to COVID-19. Identifying public attitudes and perceptions on COVID-19 vaccination is essential to strengthening the vaccination programmes.

Factors affecting clinical outcome in COVID-associated rhino-orbito-cerebral mucormycosis (CAROM) patients-An ambispective, single-arm, observational study.

Background: COVID-associated Rhino-Orbito-Cerebral Mucormycosis (CAROM) appeared as an epidemic in India during the second wave of the COVID-19 pandemic during the months of March to May 2021. Though many reports have highlighted cross sectional and short-term attributes related to CAROM, long term follow up data is sparse.

Objective: This report aims to analyze the follow-up outcomes in consecutive patients presenting to us during the epidemic.

Optimizing leachate treatment with titanium oxide-impregnated activated carbon (TiO@ASC) in a fixed-bed column: characterization, modeling, and prediction study.

This research focused on the application of a fixed bed column filled with immobilized titanium oxide-loaded almond shell carbon (TiO@ASC) for the treatment of leachate. The adsorption performance of synthesized TiO@ASC in fixed bed column is analyzed using adsorption experiments and modeling study. The characteristics of synthesized materials are determined by several instrumental techniques like BET, XRD, FTIR, and FESEM-EDX.

An efficient computational protocol for template-based design of peptides that inhibit interactions involving SARS-CoV-2 proteins.

The RNA-dependent RNA polymerase (RdRp) complex of SARS-CoV-2 lies at the core of its replication and transcription processes. The interfaces between holo-RdRp subunits are highly conserved, facilitating the design of inhibitors with high affinity for the interaction interface hotspots. We, therefore, take this as a model protein complex for the application of a structural bioinformatics protocol to design peptides that inhibit RdRp complexation by preferential binding at the interface of its core subunit nonstructural protein, nsp12, with accessory factor nsp7.

Hematopoietic stem-cell transplantation in a zoo of multidrug-resistant organisms: Data from a cancer center in eastern India.

Background: Infections by multidrug-resistant organisms (MDRO) are a major hurdle in hematopoietic stem-cell transplants (HSCTs). Conditioning regimens lead to mucosal barrier injury, which in-turn leads to transmigration of gut bacteria and sepsis. Pre-transplant stool and throat surveillance cultures can guide empirical antibiotic policy during the neutropenic period.

Multi-drug resistant (MDR) and extensively drug-resistant (XDR) bacteraemia rates among cancer patients in an oncology hospital in eastern India: an 11-year retrospective observational study.

Background: Trend analysis of bacteraemias caused by multi-drug resistant (MDR) and extensively drug resistant (XDR) bacteria helps to assess efficacy of infection prevention and control (IPC) practices. Data on the trends of MDR and XDR bacteraemias are lacking from cancer patients in India.

Aims: To report antibiotic resistance rates over time in bacteraemias and to assess the effect of IPC practices where patient isolation facilities were limited on the rates and trends of MDR and XDR bacteraemias from a cancer centre in eastern India.

Utilization of Construction and Demolition Mix Waste in the Fired Brick Production: The Impact on Mechanical Properties.

Hazardous giant pharyngoesophageal liposarcoma.

A man in his early 80s presented to the otorhinolaryngology department with progressively worsening dysphagia to solids and a recent episode of difficulty breathing accompanied by a very brief expulsion of a solid mass from the mouth. Based on the endoscopic appearance of a fatty lesion of an elongated mass with a thick stalk on the posterior pharyngeal wall, a diagnosis of the benign fibrovascular polyp was given after clinical and radiological correlation. The pharyngeal polyp was resected at the base of its pedicle by transoral endoscopy with a thunder beat vessel sealing device.
