AI Article Synopsis
- The study aimed to analyze how symptoms evolve in patients with symptomatic severe aortic stenosis (sSAS) after undergoing valve replacement and the factors that predict whether these symptoms persist.
- Out of 451 patients studied, approximately 57% continued to experience symptoms after the procedure, mainly dyspnea and heart failure, highlighting the complexity of post-operative recovery.
- Factors such as age, body mass index, and previous heart failures were linked to persistent symptoms, which in turn were associated with higher overall mortality rates over a follow-up period of about 56 months.
Article Abstract
Objective: To describe the evolution of symptoms in patients with symptomatic severe aortic stenosis (sSAS) undergoing valve replacement, the predictors of the persistence of these symptoms, and their prognostic significance. The evolution of symptoms after intervention in sSAS and their association with outcome are unknown.
Patients And Methods: Data from patients with sSAS who underwent intervention were collected. All-cause mortality and cardiovascular mortality were considered events. The evolution of symptoms and their association with events were studied.
Results: In this study, 451 consecutive patients with sSAS and no other valvular or coronary disease who were alive 30 days after intervention were included. Before valve replacement, 133 of the 451 patients (29.5%) had congestive heart failure requiring hospitalization. Of the remaining 318 patients, 287 (90.2%) had dyspnea on effort, 129 (40.6%) had angina, and 59 had syncope (18.6%). Symptoms disappeared after intervention in 192 of the 451 patients (42.6%) and remained in 259 (57.4%): 193 dyspnea, 9 angina, 17 syncope, and 60 admission for heart failure. Syncope on effort persisted in 4 of 33 patients (12.1%) and at rest in 11 of 20 (55.0%; P<.001). Age, body mass index, previous admission for heart failure, and chronic obstructive pulmonary disease were independently related to persistence of symptoms. Over a median follow-up of 56 months in our cohort of 451 patients, 129 deaths were registered (28.6%), 40 of which were cardiovascular (8.9%). Age, chronic obstructive pulmonary disease, chronic kidney disease, atrial fibrillation, heart failure, and persistence of symptoms were independently associated with all-cause mortality.
Conclusion: Symptoms attributed to SAS remain after intervention in a high proportion of patients, particularly dyspnea on effort and syncope at rest. The persistence of symptoms after intervention identifies patients with poor outcome.

Rabies is a deadly neurotropic, zoonotic disease with a mortality rate of 100% after symptoms appear. Rabies virus (RABV) is the primary cause of rabies disease in humans, and it mainly spreads via dog bites in developing countries. Over the course of RABV evolution, multiple RABV variants, called clades, have emerged.

Background: Proctocolectomy with ileal pouch-anal anastomosis is the treatment of choice for patients with ulcerative colitis with medical refractory disease or dysplasia. The aim of this research was to describe the evolution of ileal pouch-anal anastomosis surgery and surgical outcomes over a three-decade interval in a high-volume referral centre.
Methods: All consecutive patients undergoing ileal pouch-anal anastomosis for ulcerative colitis between 1990 and 2022 at the University Hospitals of Leuven were retrospectively included.

From a One Health perspective, dogs and cats have begun to be recognized as important reservoirs for clinically significant multidrug-resistant bacterial pathogens. In this study, we investigated the occurrence and genomic features of ESβL producing Enterobacterales isolated from dogs, in the province of Imbabura, Ecuador. We identified four isolates expressing ESβLs from healthy and diseased animals.

Vitamin K is essential to produce functional vitamin K-dependent coagulation factors (prothrombin, factors VII, IX, and X). Vitamin K antagonists inhibit the normal activation of these factors, leading to bleeding manifestations of variable severity. Long-acting vitamin K antagonists or superwarfarins were developed as rodenticides and have a significantly longer half-life and greater potency when compared to warfarin.

Patterns of DKD onset and progression have shifted in recent years because of population aging and advances in the treatment of diabetes. Prevention of the onset and progression of micro/macro-albuminuria is possible through comprehensive and strict management of lifestyle, blood glucose, blood pressure, and lipids in people with diabetes and early DKD.
