Objective: Cytonuclear gradings in the breast carcinoma raise the level of FNA reportage and improves patient management. Our aim was to evaluate and compare two cytological grading methods (Robinson's and Mouriquand's) in breast carcinoma and correlate it with Nottingham modification of Scarff-Bloom-Richardson (SBR) histological grading.
Materials And Methods: 30 cytologically proven cases of infiltrating ductal carcinoma were graded cytologically and histologically. Cytograding was done by Robinson's and Mouriquand's methods (grades I to III) followed by comparison of the two methods. Cytogradings were correlated with SBR grading method. Sensitivity, specificity, diagnostic accuracy, and concordance and discordance rates were evaluated.
Results: An overall concordance of 76.66% between cytogradings, of 83.33% between Robinson's method and SBR, and of 66.66% between Mouriquand's method and SBR was seen. Robinson's method correlated best with SBR in all the three nuclear grades. Robinson's method showed a diagnostic accuracy of 90% with 91.30% sensitivity while Mouriquand's method had an accuracy of 76.66% with 95.65% sensitivity. The specificity by Mouriquand's method was quite low (14.28%) as compared to Robinson's method (85.71%).
Conclusion: Comprehensive cytological grading of breast cancer by Robinson's method seems better because of more objective set of criteria, easy reproducibility, and specificity.

Objectives: Race and gender concordance between physicians and patients is associated with reductions in healthcare disparities. However, the diversity of the medical workforce does not mirror the population; some of the greatest deficiencies exist in the surgical workforce. We conducted a pilot study focused on early recruitment of diverse college students in our region, with a concurrent needs assessment of their specific barriers to entering the field of surgery.

Introduction: SCLC is characterized by aggressiveness and limited treatment options, especially in extensive-stage SCLC (ES-SCLC). Immunotherapy added to the platinum-etoposide combination has recently become standard in this setting. This retrospective study aims to evaluate the real-world effectiveness of chemo-immunotherapy in patients with ES-SCLC, focusing on subpopulations excluded from clinical trials.

Background: Extended reality (XR) technologies are increasingly being used to reduce health and procedural anxieties. The global effectiveness of these interventions is uncertain, and there is a lack of understanding of how patient outcomes might vary between different contexts and modalities.
Objective: This research used panoramic meta-analysis to synthesize evidence across the diverse clinical contexts in which XR is used to address common outcomes of health and procedural anxiety.
