Background: Increasing studies have suggested that surgical resection (SR) or liver transplantation (LT) could bring survival benefits for patients with hepacelluar carcinoma (HCC) beyond Milan criteria. This study compared the long-term survival of patients beyond the Milan criteria who received SR or LT.

Material And Methods: A total of 461 HCC patients were retrospectively collected. Analysis was performed using propensity score matching (PSM), the Kaplan-Meier method and the Cox proportional hazards model.

Results: Prognosis was significantly better for the LT group than the SR group before (P < 0.001) and after PSM(p = 0.003). In subgroup analysis, for patients with lower AFP level, the 1-, 3-, and 5-year OS rates for the two groups were significantly different (86.7, 71.9, and 71.9% for group LT vs. 75.8, 48.1, and 10.7% for group SR, P = 0.003). For patients with smaller tumor size, the 1-, 3-, and 5-year OS rates were 78.3, 66.7, and 66.7% for group LT, and 83.8, 42.6, and 18.6% for group SR, p = 0.009). Transplantation was a favorable factor associated with prognosis before and after propensity score matching (HR 2.643).

Conclusion: Our propensity model suggested that LT provided significantly better long-term survival than SR for HCC beyond Milan criteria before and after PSM.

Background: There is still a significant proportion of patients with rheumatoid arthritis (RA) in whom multiple therapeutic lines are ineffective. These cases are defined by the EULAR criteria as Difficult-to-Treat RA (D2T-RA) for which there is limited knowledge of predisposing factors.

Objective: To identify the clinical features associated with D2T-RA in real-life practice.

Evaluation of renal functional reserve with oral protein load or new ultrasound test.

J Nephrol

Department of Medicine, Surgery and Neurosciences, Nephrology, Dialysis and Transplantation Unit, University Hospital of Siena, Siena, Italy.

Background: Renal functional reserve (RFR) measures the difference between the stimulated glomerular filtration rate (GFR) and the baseline GFR to detect early signs of renal functional decline. The protein load test (RFR-T) is the gold standard for RFR assessment but is a complicated procedure. Renal intraparenchymal resistance index (RRI) variation test (DRRI-T) is a non-invasive method to measure renal function reserve using ultrasound.

Breast cancer is the most frequent non-dermatologic malignancy in women. Breast cancer is characterized by the expression of the human epidermal growth factor receptor type 2 (HER2), and the presence or lack of estrogen receptor (ER) and progesterone receptor (PR) expression. HER2 overexpression is reported in about 20 to 25% of breast cancer patients, which is usually linked to cancer progression, metastases, and poor survival.

Background: Primary Progressive Aphasia (PPA) is a neurodegenerative disorder primarily affecting language abilities, with clinical variants (nonfluent/agrammatic variant [nfvPPA], semantic variant [svPPA], logopenic variant [lvPPA], and mixed-PPA [mPPA]) categorized based on linguistic features. This study aims to compare PPA cohorts of native speakers of two different languages: English (an analytic language with deep orthography) and Italian (a synthetic language with shallow orthography).

Methods: We considered 166 English participants (70 nfvPPA, 45 svPPA, 42 lvPPA, 9 mPPA) and 106 Italian participants (14 nfvPPA, 20 svPPA, 42 lvPPA, 31 mPPA).

Introduction: Unilateral sphenoid sinus opacification on computed tomography is caused by a variety of pathologies including inflammatory and infectious sinusitis, benign and malignant tumors, and encephaloceles. The purpose of this study was to report craniofacial pain locations and outcomes in inflammatory unilateral sphenoid sinusitis (USS) patients who underwent endoscopic sinus surgery (ESS).

Methods: A multi-institutional retrospective cohort study was conducted on all adult patients who had ESS for USS from 2015 to 2022.
