Objectives: Breast cancer (BC) patients represent a high-risk population for experiencing chemotherapy-induced nausea and vomiting (CINV), since they frequently receive highly emetogenic anthracycline-cyclophosphamide-based (AC) chemotherapy, and are often female and young, two predisposing risk factors for CINV. Guidelines recommend the combination of a neurokinin-1 receptor antagonist (NKRA), 5-hydroxytryptamine-3 RA (5-HTRA), and dexamethasone (DEX) for CINV prophylaxis in AC-treated patients. This post-hoc analysis evaluated the efficacy of NEPA, a fixed combination of netupitant (NETU [NKRA]) and palonosetron (PALO [5-HTRA]) in BC patients from two phase III studies.
Methods: Overall, 1460 BC patients received AC (Study 1) or non-AC (Study 2) therapy over 6060 cycles. Randomized patients received DEX with either NEPA or oral PALO (Study 1), or NEPA or aprepitant+oral PALO (Study 2) before chemotherapy.
Results: In AC-receiving patients, overall complete response (CR) rates with NEPA+DEX were statistically significantly higher than oral PALO+DEX rates (cycles 1-4: 73.9% vs 65.9%, 80.0% vs 66.0%, 83.6% vs 69.9%, 83.6% vs 74.4%, respectively). Overall, no significant nausea (NSN) rates were also superior with NEPA+DEX vs oral PALO+DEX (respectively, 74.2%-79.9% vs 68.5%-74.9%). A greater proportion of NEPA+DEX patients experienced "no-impact-on-daily-life" due to CINV (78.4% vs 71.4%) in cycle 1. In non-AC-receiving patients, prophylaxis with NEPA+DEX resulted in high CR and NSN rates across 1-4 chemotherapy cycles; no formal comparison with the control arm was performed.
Conclusion: NEPA+DEX administered as a single dose is an effective option for preventing CINV in BC patients receiving AC and non-AC, across multiple chemotherapy cycles.

Objective: Despite diagnostic criteria refinements, Parkinson's disease (PD) clinical diagnosis still suffers from a not satisfying accuracy, with the post-mortem examination as the gold standard for diagnosis. Seminal clinicopathological series highlighted that a relevant number of patients alive-diagnosed with idiopathic PD have an alternative post-mortem diagnosis. We evaluated the diagnostic accuracy of PD comparing the in-vivo clinical diagnosis with the post-mortem diagnosis performed through the pathological examination in 2 groups.

Background: Kidney tumors, common in the urinary system, have widely varying survival rates post-surgery. Current prognostic methods rely on invasive biopsies, highlighting the need for non-invasive, accurate prediction models to assist in clinical decision-making.
Purpose: This study aimed to construct a K-means clustering algorithm enhanced by Transformer-based feature transformation to predict the overall survival rate of patients after kidney tumor resection and provide an interpretability analysis of the model to assist in clinical decision-making.

: Major Depressive Disorder (MDD) is a prevalent and debilitating mental disorder that has been linked to hyperhomocysteinemia and folate deficiency. These conditions are influenced by the methylenetetrahydrofolate reductase () gene, which plays a crucial role in converting homocysteine to methionine and is essential for folate metabolism and neurotransmitter synthesis, including serotonin. : This study explored the association between and polymorphisms among Saudi MDD patients attending the Erada Complex for Mental Health and Erada Services outpatient clinic in Jeddah, Saudi Arabia.

This study aimed to determine the risk of emergency admission by ambulance in patients taking potentially inappropriate medications (PIMs). We included 273,932 patients aged over 75 years of age admitted between January 1, 2019, and December 31, 2019, using the Japan Medical Data Center medical insurance database containing anonymized patient data. We excluded patients without a history of admission.
