Long-Term Success With a TDM-1 Biosimilar in Recurrent HER2-Positive Breast Cancer With Multisite Metastases: A Comprehensive Case Study.

This case report highlights the treatment approaches for breast cancer with metastasis to multiple sites, including the brain, liver, lungs, and bones. It also explores the role of trastuzumab emtansine (T-DM1) and its biosimilar as targeted therapies for HER2-positive breast cancer in long-term treatment. A 54-year-old postmenopausal female patient with recurrent breast cancer and metastasis was treated with trastuzumab and paclitaxel (12 cycles), followed by trastuzumab maintenance therapy (71 cycles).

PD-L1 expression in head and neck squamous cell carcinoma and its clinical significance: A prospective observational study from a tertiary care centre.

Background: Programmed Death Ligand 1 (PD-L1) expression in tumor cells contribute to tumor immunity and therapies directed against it, have shown encouraging results in recent years. As there is limited data on the significance of PD-L1 expression in Head and Neck Squamous Cell Carcinoma (HNSCC) from India, we aimed to study the PD-L1 expression and its relation with different clinic-pathological parameters in patients of HNSCC from a tertiary care center in Eastern India.

Methods: A prospective evaluation of HNSCC patients diagnosed and managed at our center over a period of two and half years, was performed.

Evolution of Diagnostic and Forensic Microbiology in the Era of Artificial Intelligence.

Diagnostic microbiology plays a vital role in managing infectious diseases, combating antimicrobial resistance, and containment of outbreaks. During the fourth industrial revolution, when artificial intelligence (AI) became an essential part of our day-to-day lives, its integration into healthcare would further revolutionize our knowledge and potential. Although in the budding stage, AI with machine learning is being increasingly utilized in various aspects of diagnostic microbiology.

The Gram stain: Implication in blood culture reporting.

Bloodstream infections are life-threatening. They are responsible for prolonged hospital stays and high healthcare costs. Clinical microbiology has an essential role to play in its management.

Persistence of SARS-CoV-2 in COVID-19 patients during the second wave of the pandemic in India.

Introduction: India witnessed the catastrophic second wave of COVID-19 during the summer months of 2021. Many patients with non-resolution of symptoms admitted to dedicated COVID-19 treatment centers required prolonged inpatient care which led to the unavailability of beds for other COVID-19 patients. The objective of this study was to determine the duration of SARS-CoV-2 positivity in moderate and severe COVID-19 patients requiring long-term pulmonary care as well as to find out the association between different variables with the persistence of the virus.
