Background: The aim of the study was to determine the upgrade rate on excision of intraductal papilloma (IDP) without atypia diagnosed on breast core needle biopsy (CNB).
Methods: We searched our pathology department database for breast CNB with a diagnosis of IDP from 2013 to 2018. The exclusion criteria included radiologic-pathologic discordance, atypia on the same CNB, absence of histologic slides to review or absence of excision information. Upgrade was defined as ductal carcinoma in situ (DCIS) or invasive cancer identified on excision.
Results: 126 IDP without atypia cases from 94 patients were identified. The upgrade rate was 1.58% (2/126). Both upgrade cases showed DCIS with low and intermediate nuclear grade. Histologic size of IDP ≥1 cm was the only statistically significant predictor factor for an upgrade on excision.
Conclusion: The results suggest that non-surgical management of patients with radiologic-pathologic concordant IDP without atypia diagnosed on CNB may be appropriate in routine practice.

Background: One of the common complications in spinal surgery patients is deep surgical site infections (SSIs). Deep SSIs refer to infections that involve the deeper soft tissues of the incision, such as the fascia and muscle layers. This complication can lead to prolonged hospitalization, repeated surgeries, and even life-threatening conditions.

CO/CH separation is crucial for biogas upgrading. In this study, the bamboo-derived activated carbons (BACs) were prepared with different ratios of potassium hydroxide (KOH)/bamboo charcoal (BC), and the hybrid sorbents of aqueous BACs were developed for CO/CH separation. Both the gas solubility and sorption rate were measured, and Henry's constant and liquid-side mass-transfer coefficient as well as the CO/CH selectivity were calculated.

: B3 breast lesions, characterized by uncertain malignant potential, pose a significant challenge for clinicians. With the increasing use of preoperative biopsies, there is a need for careful management strategies, including watchful waiting, vacuum-assisted excision (VAE), and surgery. This study aims to assess the concordance between preoperative biopsy findings and postoperative histology, with a focus on evaluating the positive predictive value (PPV) for malignancy in B3 lesions.

Ambient dose rate surveying has the objective, in most cases, to quantify terrestrial radiation levels. This is true in particular for Citizen Monitoring projects. Readings of detectors, which do not provide spectrally resolved information, such as G-M counters, are the sum of contributions from different sources, including cosmic radiation.

In this paper, we investigated the efficient metal-free phosphorus-nitrogen (PN) catalyst and used the PN catalyst to degrade waste PU with two-component binary mixed alcohols as the alcohol solvent. We examined the effects of reaction temperature, time, and other factors on the hydroxyl value and viscosity of the degradation products; focused on the changing rules of the hydroxyl value, viscosity, and molecular weight of polyols recovered from degradation products with different dosages of the metal-free PN catalyst; and determined the optimal experimental conditions of reaction temperature 180 °C, reaction time 3 h, and PN dosage 0.08%.
