The impact of special histological types (ST) in triple-negative breast cancer (TNBC) and its association with overall outcome has gained increasing relevance as survival has been linked to specific histological TNBC subtypes. We evaluated the clinicopathological and survival data of 598 patients with 613 TNBCs, including 464 TNBCs of no special type (NST) and 149 TNBCs ST (low-grade, n = 12, 8.1%; high-grade, n = 112, 75.

Methods: We conducted a scoping review that was methodologically informed by the Arskey and O'Malley's 5 step framework and theoretically informed by the Consolidated Framework for Implementation Research (CFIR). A systematic search of six databases was conducted for peer-reviewed literature.
Background: Advances in Human Immunodeficiency Virus (HIV) treatment have reduced mortality rates and consequently increased the number of individuals with HIV living into older age. Despite this, people aged 50 years and older have been left behind in recent HIV treatment and prevention campaigns, and a gold-standard model of care for this population has not yet been defined. Developing evidence-based geriatric HIV models of care can support an accessible, equitable, and sustainable HIV health care system that ensures older adults have access to care that meets their needs now and in the future.

Methods: A scoping review methodology of academic peer-reviewed and gray English language literature was employed using six academic literature databases and one gray literature database. We further performed comprehensive searches of relevant search engines and organization websites and bibliographic hand searches to identify additional academic and gray literature.
Background: Despite being one of the largest medical specialty training programmes in Australasia, there is no standardised method for selection into Basic Physician Training (BPT), and limited data exist regarding current practices.
Aims: To address existing knowledge gaps, we aimed to create a 'snapshot' of current BPT selection practices and explore the perspectives of Directors of Physician Education (DPEs) regarding trainee selection.
Methods: An electronic survey of DPEs from adult and paediatric medicine BPT sites in Australia and New Zealand was undertaken in January-February 2022.
Background: Currently, no standardized methods exist to assess the geriatric skills and training needs of internal medicine trainees to enable them to become confident in caring for older patients. This study aimed to describe the self-reported confidence and training requirements in core geriatric skills amongst internal medicine residents in Toronto, Ontario using a standardized assessment tool.
Methods: This study used a novel self-rating instrument, known as the Geriatric Skills Assessment Tool (GSAT), among incoming and current internal medicine residents at the University of Toronto, to describe self-reported confidence in performing, teaching and interest in further training with regard to 15 core geriatric skills previously identified by the American Board of Internal Medicine.
A 72-year-old woman was referred to us with typical symptoms of paroxysmal supraventricular tachycardia for electrophysiological diagnostics and catheter ablation. During the first session of catheter ablation, a probing of the right ventricle was not successful. Therefore, an angiography of the central veins was performed.

It is a key regulator of urogenital development and homeostasis but also plays a role in other organs including the spleen and the heart. More recently additional functions for Wt1 in the mammalian central nervous system have been described.

Working digitally can lead to changes in work organization and social interactions, as well as work pace and workload. Online counseling is more and more integrated in social counseling. Research exists on employees' and users' attitudes towards online counseling as well as on the advantages and disadvantages of online counseling.

To determine if this role was conserved in zebrafish, we analyzed pdgfb and pdgfrb mutant lines. Similar to mouse, pdgfb and pdgfrb mutant zebrafish lack brain pericytes and exhibit anatomically selective loss of vascular smooth muscle coverage.

In these contexts, RNA-sequencing (RNA-seq) provides mechanistic insights by identifying transcriptome changes between experimental conditions. Application of RNA-seq relies on accurate transcript annotation for a genome of interest.

The aim of the study was to evaluate the spectrum of cardiopulmonary pathology of COVID-19 based on (non-minimal invasive) autopsies performed on 14 COVID-19 decedents. Bilateral diffuse alveolar damage (DAD) was found in all patients.

The aim of the study was to investigate the molecular profile in Swiss never smokers with lung adenocarcinoma and to correlate the mutation status with clinicopathologic and demographic patient characteristics and outcome.
Methods: One hundred thirty-eight never smokers diagnosed with lung adenocarcinoma at the University Hospital Zurich between 2011-2018 were included in the study.
Organ regeneration is preceded by the recruitment of innate immune cells, which play an active role during repair and regrowth. Here, we studied macrophage subtypes during organ regeneration in the zebrafish, an animal model with a high regenerative capacity. We identified a macrophage subpopulation expressing Wilms tumor 1b (wt1b), which accumulates within regenerating tissues.

Mutations in WTX are found in Wilms tumor, a form of pediatric kidney cancer and in patients suffering from OSCS (Osteopathia striata with cranial sclerosis), a sclerosing bone disorder. Functional data suggest WTX to be an inhibitor of the Wnt/β-catenin signaling pathway.

We find that in early development, the transcription factor foxc1b is expressed in mesenchymal cells that associate with the vascular endothelium. Using timelapse imaging, we observe that foxc1b expressing mesenchymal cells differentiate into acta2 expressing vascular mural cells.
