Postprocedural Contrast-Associated Acute Kidney Injury and Prognosis of Patients Undergoing Recanalization of Chronic Total Occlusions.

Percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) requires advanced techniques and prolonged procedural efforts, often necessitating high contrast volumes, which may increase the risk of contrast-associated acute kidney injury (CA-AKI). However, evidence suggests that factors beyond contrast exposure contribute to CA-AKI, though data specific to CTO PCI remain limited. Patients undergoing contemporary CTO PCI at our university-affiliated tertiary care center were enrolled.

Extremely low frequency pulsed magnetic field inhibits myocardial damage and apoptosis in rats with CLP-induced sepsis: A histopathological and immunohistochemical evaluation.

We aimed to investigate whether pulsed magnetic fields (PMFs) (1 mT) may have preventive effects on myocardial damage and apoptosis in rats with sepsis. Twenty-eight adult Wistar albino rats were evenly distributed among four experimental groups, each consisting of seven rats: SH, LF-PMF, HF-PMF, and CLP. Sepsis induction was carried out via the cecal ligation and puncture (CLP) method, while rats in the LF-PMF and HF-PMF groups were exposed to 7.

Bone mineral density and TAVR outcome: A comparative analysis between patients with enhanced and non-enhanced TAVR CT scans.

Background: Preprocedural evaluation, including frailty estimation, is crucial in managing patients undergoing Transcatheter Aortic Valve Replacement (TAVR). This involves mandatory computed tomography (CT) scans for assessing body composition parameters. The impact of low bone mineral density (BMD) on TAVR outcomes remains unclear, especially when measured using both non-enhanced and contrast-enhanced CT scans.

How to address the coronaries in TAVI candidates: can the need for revascularization be safely determined by CT angiography only?

Coronary artery disease (CAD) remains one of the most frequent comorbidities among transcatheter aortic valve implantation (TAVI) candidates. Whether routine assessment of CAD by invasive coronary angiography (CA) and eventual peri-procedural percutaneous coronary intervention (PCI) is generally beneficial in TAVI patients has recently been heavily questioned. CA carries significant risks, such as kidney injury, bleeding, and prolonged hospital stay, and may frequently be unnecessary if significant stenoses of the proximal coronary segments can be ruled out on computed tomography angiography.

Harmonic enhancement to optimize EOG based ocular activity decoding: A hybrid approach with harmonic source separation and EEMD.

Intelligent robotic systems for patients with motor impairments have gained significant interest over the past few years. Various sensor types and human-machine interface (HMI) methods have been developed; however, most research in this area has focused on eye-blink-based binary control with minimal electrode placements. This approach restricts the complexity of HMI systems and does not consider the potential of multiple-activity decoding via static ocular activities.

The objective of this investigation was to assess the impact of Roy's adaptation Model-focused education on medication adherence and psychosocial compliance in hypertensive patients.

Methods: This study was conducted in N = 60 hypertensive patients (n = 30 control group and n = 30 experimental group) based on a randomized controlled trial design.

Low Bone Mineral Density on Computed Tomography: Association with Poor Survival after Transcatheter Aortic Valve Replacement.

Transcatheter aortic valve replacement (TAVR) has evolved as first-line therapy for severe aortic valve stenosis (AS), with pre-procedural computed tomography (CT) providing critical anatomical information. While primarily used for anatomical planning, TAVR-CT also offers an opportunity to assess low bone mineral density (BMD), a known indicator of frailty. Despite this, the prognostic role of BMD in TAVR patients remains unknown.

Total Muscle Area and Visceral Adipose Tissue Measurements for Frailty Assessment in TAVR Patients.

Transcatheter aortic valve replacement (TAVR) is a treatment option for severe aortic valve stenosis. Pre-TAVR assessments, extending beyond anatomy, include evaluating frailty. Potential frailty parameters in pre-TAVR computed tomography (CT) scans are not fully explored but could contribute to a comprehensive frailty assessment.

Mixed aortic valve disease: association with paravalvular leak and reduced survival after transcatheter aortic valve replacement.

Aims: Transcatheter aortic valve replacement (TAVR) revolutionized the therapy of severe aortic stenosis (AS) with rising numbers. Mixed aortic valve disease (MAVD) treated by TAVR is gaining more interest, as those patients represent a more complex cohort as compared with isolated AS. However, concerning long-term outcome for this cohort only, limited data are available.

Altered blood flow due to larger aortic diameters in patients with transcatheter heart valve thrombosis.

The etiology of transcatheter heart valve thrombosis (THVT) and the relevance of the aortic root geometry on the occurrence of THVT are largely unknown. The first aim of this pilot study is to identify differences in aortic root geometry between THVT patients and patients without THVT after transcatheter aortic valve implantation (TAVI). Second, we aim to investigate how the observed difference in aortic diameters affects the aortic flow using idealized computational geometric models.

Routine 4D Cardiac CT to Identify Concomitant Transthyretin Amyloid Cardiomyopathy in Older Adults with Severe Aortic Stenosis.

Background Transthyretin amyloid cardiomyopathy (ATTR-CM) often coexists with severe aortic stenosis (AS). Although strain analysis from cardiac MRI and echocardiography was demonstrated to predict coexisting ATTR-CM, comparable data from four-dimensional (4D) cardiac CT are lacking despite wide availability. Purpose To evaluate the diagnostic performance of 4D cardiac CT-derived parameters in identifying ATTR-CM in older adults considered for transcatheter aortic valve implantation (TAVI).

Initiating luteal phase support with sc progesterone based on low serum progesterone on the transfer day in true natural cycle frozen embryo transfers.

Introduction: Concerning contemporary fertilisation (IVF) practice, the use of frozen embryo transfer (FET) cycles has become more common than fresh transfers. Natural cycle (NC), programmed artificial cycle and mild stimulation cycle are primary endometrium preparation cycles. Monitoring serum progesterone levels in FET cycles are in the scope of current research focus.

Impact of COVID-19 Surge Periods on Clinical Outcomes of Transcatheter Aortic Valve Implantation.

Healthcare systems adopted various strategies to minimize the impact of the COVID-19 pandemic on clinical outcomes of patients with symptomatic severe aortic stenosis referred for transcatheter aortic valve implantation (TAVI). We aimed to compare baseline characteristics and procedural and clinical outcomes of patients who underwent TAVI during COVID-19 surge periods with those of patients who underwent TAVI during the nonsurge and prepandemic periods. In the prospective Bern TAVI registry, the pandemic period was divided into surge and nonsurge periods on the basis of the mean number of occupied beds in the intensive care unit in each month and matched with 11 months immediately preceding the pandemic.

Insight in schizophrenia is associated with psychoeducation and social support: Testing a new more comprehensive insight tool in Turkish schizophrenia patients.

Insight is a continuous and multidimensional phenomenon, including awareness of having an illness, the presence of symptoms and accurate symptom attribution, the need for treatment, and the consequences of treatment. Good insight into illness is associated with better adherence to treatment, better cognitive, psychosocial, and vocational functioning along with less symptom severity, decreased relapses, and hospitalizations. Several tools are used for insight evaluation.

Incidental detection of malignancy during preprocedural workup for transcatheter aortic valve implantation: A longitudinal cohort study.
