Concepts: Subarachnoid hemorrhage


Regulatory T cells (Tregs) infiltrate into a variety of tumour tissues and associate with poor prognosis in humans. However, data on association of Treg infiltration with prognosis is limited in canine tumours. The purpose of this study was to examine the number of tumour-infiltrating Tregs and its association with overall survival (OS) in dogs with malignant tumours. The following 168 canine tumours were included: 37 oral malignant melanomas (OMMs); 14 oral squamous cell carcinomas (OSCCs); 16 pulmonary adenocarcinomas (PAs); 37 mammary carcinomas (MCs); 36 mast cell tumours (MCTs) and 28 hepatocellular carcinomas (HCCs). Normal tissues were obtained from 8 healthy dogs as controls. The number of forkhead box P3 (Foxp3)-positive Tregs in intratumoral and peritumoral areas was investigated by immunohistochemistry. OS was compared between high and low Treg groups. The number of intratumoral and peritumoral Foxp3-positive Tregs was significantly higher in OMM, OSCC, PA and MC compared with each normal tissue. There were few Foxp3-positive Tregs in MCT and HCC. With intratumoral Tregs, the OS in the high Treg group was significantly shorter than that in the low Treg group in OMM, OSCC and PA. With peritumoral Tregs, there was no significant difference for OS between the 2 groups in each tumour type. These results suggest that Tregs infiltrate into a variety of canine tumours and the abundance of Tregs are associated with poor prognosis in some solid tumour types.

Asthma exacerbations can do a lot of harm to the patients and consume large amounts of medical resources. This consensus is based on the domestic and foreign guidelines and literatures to standardize the evaluation and management of asthma exacerbations in China. Asthma exacerbations are characterized by a progressive increase in symptoms of shortness of breath, cough, wheezing or chest tightness and progressive decrease in lung function, and usually require modification of treatment. Recognizing risk factors and triggering factors of asthma exacerbations is helpful for the prevention and long-term management. Evaluation of asthma exacerbations is based on symptoms, lung function, and arterial blood gas. Management is stratified according to the severity of disease. Different regimens to treat asthma exacerbations are discussed in this consensus. Glucocorticoids should be used properly. Overuse of antibiotics should be avoided. Management of life-threatening asthma is discussed separately. Special attention should be paid in some special respects, such as asthma during peri-operation period, gestation period, and childhood. Diagnosis and management of complications are also of great significance and are discussed in details.

This study sought to investigate predictors and safety of next-day discharge (NDD) after transcatheter aortic valve replacement (TAVR).


The aim of this post hoc analysis from the RESPOND (Repositionable Lotus Valve System-Post-Market Evaluation of Real World Clinical Outcomes) post-market study was to assess the final implantation depth on the contrast aortogram after Lotus valve (Boston Scientific, Marlborough, Massachusetts) transcatheter aortic valve replacement (TAVR) and to correlate with permanent pacemaker implantation (PPI) and paravalvular leak (PVL).


The aim of this study was to determine whether the association of small label size of the surgical valve with increased mortality after transcatheter valve-in-valve (ViV) implantation is, at least in part, related to pre-existing prosthesis-patient mismatch (PPM) (i.e., a bioprosthesis that is too small in relation to body size).

Concepts: The Association


This study sought to evaluate the Medtronic Evolut PRO Transcatheter Aortic Valve System in patients with severe symptomatic aortic stenosis.
