Klebsiella pneumoniae is a leading cause of anti-microbial resistance in healthcare-associated infections that have posed a severe threat to neonatal and wider community. The escalating crises of antibiotic resistance have compelled researchers to explore an innovative arsenal beginning from natural resources to chemical modifications in order to overcome the ever-increasing resistance issues. The present review highlights the drug discovery efforts with a special focus on cutting-edge strategies in the hunt for potential drug candidates against MDR/XDR Klebsiella pneumoniae.

Acute exacerbations of COPD (ECOPD) are an important event in the life of a COPD patient as it causes significant deterioration of physical, mental, and social health, hastens disease progression, increases the risk of dying and causes a huge economic loss. Preventing ECOPD is therefore one of the most important goals in the management of COPD. Before the patient is discharged after hospitalization for ECOPD, it is crucial to offer an evidence-based care bundle protocol that will help minimize the future risk of readmissions and death.

Ensuring the safety and quality of drugs is a crucial component for the development of any pharmaceutical industry. This requires stringent regulation in the process of drug manufacturing and marketing. A Drug Master File (DMF) serves as a comprehensive document containing information about the quality, safety, and manufacturing procedure/facility of a drug or drug substance.

Herpes zoster (HZ), caused by the reactivation of varicella-zoster virus (VZV), typically presents as a unilateral dermatomal erythematous vesicular rash. Bilateral HZ is rare and usually associated with immunocompromise. We report the case of a 62-year-old female with no evident immunocompromise who developed bilateral thoracic HZ.

Respiratory syncytial virus (RSV) is a leading cause of respiratory infection, hospitalization and death in infants worldwide. No fully effective RSV therapy using direct antivirals is marketed. Since clinical efficacy data from naturally infected patients for such antivirals are not available yet, animal studies are indispensable to predict therapeutic intervention.

Purpose: Clinical adoption of NK cell immunotherapy is underway for medulloblastoma and osteosarcoma, however there is currently little feedback on cell fate after administration. We propose magnetic particle imaging (MPI) may have applications for the quantitative detection of NK cells.

Procedures: Human-derived NK-92 cells were labeled by co-incubation with iron oxide nanoparticles (VivoTrax™) for 24 h then excess nanoparticles were washed with centrifugation.

Objectives: In this study, we explored the efficacy of methanolic extract of Thuja orientalis (TOME) as a novel antibacterial and antibiofilm agent against a cariogenic bacterium, Enterococcus faecalis ATCC 29212.

Design: Antibacterial susceptibility studies were conducted and surface morphology analysis was performed using field emission scanning electron microscopy (FESEM). Antibiofilm activity was evaluated through both qualitative and quantitative biofilm inhibition assays and validated by microscopic analysis.

Article Synopsis
  • Spirometry is a test used to evaluate lung function by comparing it to normal levels in healthy non-smokers, focusing on metrics like forced vital capacity (FVC) and the FEV/FVC ratio.
  • The study analyzed data from over 14,000 participants aged 40 and older across 41 sites, revealing regional differences in FVC tied to factors like age and height, categorized into four regions: Europe/richer countries, Near East, Africa, and Far East.
  • Findings showed significant regional variations in FVC values between men and women, particularly in Europe compared to the Far East, but minimal differences in the FEV/FVC ratio across regions.

Introduction: Platelet function testing using serial VerifyNow P2Y12 platelet reactivity units (PRUs) is established for guiding clopidogrel antiplatelet therapy in cerebral aneurysm stenting procedures. However, for ticagrelor, the impact of serial PRU testing and the identification of safe PRU ranges remains unexplored.

Methods: Flow diversion stenting ( = 232) and stent-assisted coiling procedures ( = 83) performed 05/2017-12/2021 were reviewed.

Background & Aims: Hepatitis E virus (HEV) constitutes a substantial public health burden with ∼20 million human infections annually, including 3.3 million symptomatic cases. Appropriate treatment options for, in particular, immunocompromised patients with HEV infection and pregnant women are lacking, underscoring the urgent need for potent and safe antiviral drugs.

Molecular characterization was conducted to characterise 'Nattukuttai', a native cattle population of the north-eastern agro-climatic zone of Tamil Nadu (India), using thirty microsatellite markers. The analyses revealed a high level of genetic diversity, with a total of 294 alleles observed across all the loci, averaging 9.8 alleles per locus.

Background: Intravascular ultrasound (IVUS) guides deferral decision-making regarding the left main coronary artery (LMCA) and improves outcomes. Further studies regarding coronary physiology to guide revascularization in the LMCA are needed. Our aim was to evaluate the outcome of LMCA deferral using IVUS or coronary physiology via instantaneous wave-free ratio (iFR) or fractional flow reserve (FFR).

Background: Percutaneous coronary intervention (PCI) of saphenous vein grafts (SVG) is associated with poor outcomes and is often regarded as inferior to native vessel PCI. We investigated clinical outcomes of SVG-PCI using contemporary drug-eluting stents (DES), in a complete, nationwide population.

Methods: The complete Swedish Coronary Angiography and Angioplasty Registry (SCAAR) was used to identify all patients in Sweden who underwent SVG-PCI with a contemporary DES between 2013 and 2020.

Background: Fistulas, abnormal connections between two anatomical structures, significantly impact the quality of life and can result from a variety of causes, including congenital defects, inflammatory conditions, and surgical complications. Stem cell therapy has emerged as a promising alternative due to its potential for regenerative and immunomodulatory effects. This overview of systematic reviews aimed to assess the safety and efficacy of stem cell therapy in managing fistulas, drawing on the evidence available.

Article Synopsis
  • Tuberculosis (TB) is a major global health issue, with ongoing research aimed at developing new anti-TB medications that effectively target the disease.
  • Scientists created an open-access database containing genetic variations from over 50,000 clinical TB isolates to help understand resistance mutations seen in real-world scenarios.
  • The analysis of this database showed how specific genetic variations relate to drug resistance and the importance of genetic diversity in drug targets, making it a useful tool for drug discovery and development.

Ovarian cancer is a leading cause of death for women worldwide in part due to ineffective screening methods. In this study, we used whole-genome cell-free DNA (cfDNA) fragmentome and protein biomarker (CA-125 and HE4) analyses to evaluate 591 women with ovarian cancer, benign adnexal masses, or without ovarian lesions. Using a machine learning model with the combined features, we detected ovarian cancer with specificity >99% and sensitivity of 72%, 69%, 87%, and 100% for stages I-IV, respectively.
