Impact of porcelain aorta on outcomes in transfemoral aortic valve implantation (TAVI) with balloon-expandable valves.

Background: Current guidelines recommend transcatheter aortic valve implantation (TAVI) for patients with aortic stenosis and porcelain aorta (PA). Neurological outcomes of patients with PA undergoing TAVI with modern valves require clarification as most trials examined balloon-expandable valves (BEV) and self-expandable valves in intermediate or high-risk patients, but not specifically in patients with PA. Our aim was to compare outcomes, including stroke and mortality, in well-matched patients with and without PA who received BEV during transfemoral TAVI procedures.

Anthelmintic and therapeutic effects of the biogenic zinc oxide nanoparticles against acute kidney injury induced by Infection in rats.

Complications of parasite infections, especially kidney disease, have been linked to poorer outcomes. Acute kidney damage, glomerulonephritis, and tubular dysfunction are the most prevalent renal consequences of infection. The purpose of this study was to determine the pharmacological effects of green-produced zinc oxide nanoparticles (ZnO NPs) on infection in male Wistar rats.

Are congenital heart defects connected to more severe attention-deficit/hyperactivity disorder?: A systematic review and meta-analysis.

Background: Congenital heart defects (CHDs) are the most common cause of birth defect-related infant morbidity and mortality, affecting 1% of 40,000 births per year in the United States. On the other side, the etiology of attention-deficit/hyperactivity disorder (ADHD) is multifactorial. Multiple studies have found that cardiac surgery patients have higher morbidity of having this disorder.

Transcatheter Mitral Valve Repair via MitraClip in Patients Aged <65 Years: Multicentre 2-year Outcomes.

Background: Transcatheter mitral valve repair (TMVR) using the MitraClip has become a well-established interventional therapy and is usually performed in elderly patients. The objective of this study was to assess 2-year clinical outcomes of TMVR in patients aged <65 years at three heart centres with severe mitral regurgitation (MR) and no surgical options.

Methods: A retrospective study analysed data of 36 patients aged <65 years treated with TMVR .

Successful management of a bleeding complication during transaxillary transcatheter aortic-valve implantation: a case report.

Background: The axillary artery is an alternative access route for transcatheter aortic-valve implantation (TAVI) in patients who have unfavourable femoral arteries as well as comorbidities which preclude surgery. Transaxillary TAVI (TAx-TAVI), with a complete non-transfemoral approach, is a feasible and safe alternative even if complications like vascular closure device failure with bleeding occurs.

Case Summary: We describe here a simplified non-transfemoral TAx-TAVI approach in a 71-year-old patient with pulmonary oedema due to severe symptomatic aortic stenosis with a prohibitively high surgical risk (Society of Thoracic Surgeons Mortality 11.

In vitro anti- effect of silver nanoparticles.

is a common gastrointestinal nematode of buffaloes and cattle, primarily young calves. This parasitic infection is distributed worldwide, causing a huge economic loss due to reduced meat and milk production and animal mortality. Several studies have indicated that silver nanoparticles have an effective anthelmintic activity.

Contemporary results of transcatheter mitral valve procedures: bi-centric retrospective analysis.

Background: Transcatheter mitral valve-in-valve (TMVIV) or valve-in-ring (TMVIR) replacement offer an alternative therapy for high risk patients. We aimed to highlight the operative and postoperative results of TMVIV and TMVIR procedures.

Results: We included all patients underwent TMVIV and TMVIR procedures between 2017 and 2020 at two heart centers in Germany.

Pre-procedural predictors for multiple clips in percutaneous edge-to-edge mitral valve repair.

Background: Percutaneous mitral valve (MV) clipping for mitral regurgitation (MR) revolutionized MV repair; however, valve anatomies and pathologies vary. Often multiple clips are required, and predicting this pre-procedurally would be useful. We evaluated pre-procedural predictors for multiple clips.

Efficacy of Miltefosine and Artemether on Infected Snails with : Immunological and Histological Studies.

snails have received much attention due to their great medical importance as vectors for transmitting infection to humans. The main objective of the present work was to assess the efficacy of miltefosin a synthetic molluscicidal drug and artemether a natural molluscicidal drug. The correlation between immunological and histological observations from light and electron microscopy of the hemocytes of post treatment with both drugs was also evaluated.

Transcatheter Aortic Valve Replacement Without the Use of Contrast Medium: An Alternative Safe Implantation Technique.

Background: New transcatheter equipment and accumulated experience have stimulated further refinements in implantation techniques. We aimed to compare the outcomes of transfemoral transcatheter aortic valve replacement (TF-TAVR) with and without the use of contrast medium (CM) in patients with glomerular filtration rate (GFR) <30 mL/min/1.73 m².

Magnetic fields enhance the anti-tumor efficacy of low dose cisplatin and reduce the nephrotoxicity.

The present work was to examine a combination of therapy for a low dose of cisplatin and a magnetic field (MF) on Ehrlich carcinoma-bearing mice. In this study, a total of 50 BALB/C female mice were equally distributed into five groups. Mice from the control group did not receive MF or cisplatin.

Computed tomography-derived left atrial volume index, sex, and age to predict the presence and the extent of left atrial low-voltage zones in patients with atrial fibrillation: The ZAQ score.

Background: Pulmonary vein isolation is the cornerstone of catheter ablation in patients with atrial fibrillation (AF). However, with advanced left atrial (LA) structural changes, additional targeted catheter ablation of low-voltage zones (LVZs) has produced favorable results. Therefore, with the advent of single-shot techniques, it would be helpful to predict the presence of LVZs before an ablation procedure.

Ultrastructural characterization of Pleistophora macrozoarcidis Nigerelli 1946 (Microsporidia) infecting the ocean pout Macrozoarces americanus (Perciformes, Zoarcidae) from the gulf of Maine, MA, USA.

Pleistophora macrozoarcidis a microsporidian parasite infecting the muscle tissue of the ocean pout Macrozoarces americanus collected from the Gulf of Maine of the Atlantic Ocean, MA, USA, was morphologically described on the basis of ultrastructural features. Infection was detected as opaque white or rusty brown lesions scattered throughout the musculature of the fish mainly in the region anterior to anus. Transmission electron microscopy showed that in individual parasitized muscle cells, the infection progresses within parasite formed vesicles which are in direct contact with muscle cell elements.
