Ultrasound-based radiomic nomogram for predicting the invasive status of breast cancer: a multicenter study.

Purpose: This study aimed to develop a nomogram combining clinical, sonographic, and radiomic features to discriminate invasive breast cancer (IBC) from noninvasive breast cancer (non-IBC), and to evaluate the prognostic potential of conventional ultrasound (CUS)-based radiomic signatures in predicting breast cancer invasiveness.

Methods: A total of 403 IBCs and 221 non-IBCs were retrospectively collected from multiple institutes. The cases were divided into three subsets based on their institutional origin: a training set (n = 353), an internal test set (n = 153), and an external test set (n = 118).

Transient Atrioventricular Block as a Complication of Influenza A Virus: A Case Report.

Influenza is one of the most common respiratory viral infections, causing annual epidemics of respiratory illnesses characterized by sudden onset of fever, malaise, myalgias, cough, and other respiratory complaints. A spectrum of cardiovascular complications has also been reported in association with influenza infection. Cardiovascular involvement can occur through the direct effects of the virus on the myocardium or through the exacerbation of the existing cardiovascular disease.

Using a Web-Based Platform as an Alternative for Conducting International, Multidisciplinary Medical Conferences During the Novel COVID-19 Pandemic: Analysis of a Conference.

Background: The COVID-19 pandemic has stunted medical education activities, resulting in most conferences being cancelled or postponed. To continue professional education during this crisis, web-based conferences can be conducted via livestream and an audience interaction platform as an alternative.

Objective: The unprecedented COVID-19 pandemic has affected human connections worldwide.

Increased risk of dementia following herpes zoster ophthalmicus.

This retrospective cohort study aimed to examine the relationship between herpes zoster ophthalmicus (HZO) and the subsequent risk of dementia using a population-based database. We retrieved the study sample from the Taiwan Longitudinal Health Insurance Database 2005. The study group included 846 patients with HZO, and the comparison group included 2538 patients without HZO.

Salmonella infective endocarditis.

Objective: Salmonella endocarditis is so rarely reported that its clinical features, prognosis, and optimal treatment remain unclear. In this paper, we report a female with nontyphoid Salmonella endocarditis complicated with perivalvular abscess. We also review and summarize other cases reported in the English literature.

Bacteremic pneumonia caused by extended-spectrum beta-lactamase-producing Escherichia coli and Klebsiella pneumoniae: Appropriateness of empirical treatment matters.

Background: Clinical information about bacteremic pneumonia caused by extended-spectrum beta-lactamase (ESBL)-producing organism is limited.

Methods: A retrospective study was conducted at two medical centers in Taiwan. From May 2002 to August 2010, clinical information and outcome of adults with bacteremic pneumonia caused by ESBL-producing Escherichia coli and Klebsiella pneumoniae were analyzed.

Pneumomediastinum in patients with AIDS: a case report and literature review.

Objective: Pneumomediastinum is a rare complication of opportunistic infections in HIV-infected patients. However, the relationship between the causative pathogens and the prognosis is unclear. We report the case of a patient with AIDS presenting with community-acquired pneumonia complicated by pneumomediastinum.

Activated nickel platform for electrochemical sensing of phosphate.

We report here a highly selective enzymeless approach for the determination of phosphate (PO(4)(3-)) by flow injection analysis (FIA). In this system, the activation of barrel plated nickel electrode (Ni-BPE) in alkaline media to form a Ni(OH)(2)/NiO(OH) film was found to trigger the adsorption of phosphate at the electrode surface. Based on the suppressed current of the electrocatalytic oxidation of glucose at the activated Ni-BPE in 0.

A disposable screen-printed silver strip sensor for single drop analysis of halide in biological samples.

A screen-printed silver strip with three-electrode configuration of Ag-working, Ag-counter and Ag/Ag(x)O reference electrodes was developed for simultaneous determination of chloride, bromide and iodide in aqueous solutions. It was fabricated simply by screen-printing silver ink onto a polypropylene (PP) base. The in-situ prepared Ag/Ag(x)O reference electrode can avoid the leaching interference in chloride detection while using a conventional Ag/AgCl reference electrode.
