The Impact of Restricted Clinical Experiences During a Pandemic on Newly Graduated Nurses' Experiences: A Descriptive Study.

A multihospital study examined the impact of restricted clinical opportunities during COVID-19 on newly graduated nurses' experiences, self-reported competence, and self-reported errors upon entry into a nurse residency program and at 6 months. Newly graduated nurses' experiences (n = 2,005) were described using comparative data from cohorts before and during restricted experiences across 22 hospitals; minimal differences were observed. Nursing professional development specialists can utilize this information when creating and sustaining transition-to-practice programs.

Development of superhydrophillic tannic acid-crosslinked graphene oxide membranes for efficient treatment of oil contaminated water with enhanced stability.

In the present age of industrialization, oil contamination in the waste water has become a huge global concern due to its several negative impacts on human health and aquatic ecosystem. In order to address this problem, a novel oleophobic and super-hydrophilic graphene-based membrane has been developed using simple and cost-effective vacuum filtration methodology. Prior developing the membranes, the graphene oxide (GO) sheets were crosslinked with tannic acid (TA) molecules in order to improve their mechanical and surface properties.

Nonlinear dynamics based machine learning: Utilizing dynamics-based flexibility of nonlinear circuits to implement different functions.

The core element of machine learning is a flexible, universal function approximator that can be trained and fit into the data. One of the main challenges in modern machine learning is to understand the role of nonlinearity and complexity in these universal function approximators. In this research, we focus on nonlinear complex systems, and show their capability in representation and learning of different functions.

Association of Time Between Left Ventricular and Aortic Systolic Pressure Peaks With Severity of Aortic Stenosis and Calcification of Aortic Valve.

Importance: Diagnosis of low-gradient severe aortic stenosis (AS) is challenging. We hypothesized that the time between left ventricular (LV) and aortic systolic pressure peaks (TLV-Ao) is associated with aortic stenosis (AS) severity and may have additive value in diagnosing severe AS, especially in patients with low-gradient AS.

Objective: To investigate the diagnostic utility of measuring catheter-based TLV-Ao in patients with severe AS.

Comparative Oral Absorption of Curcumin in a Natural Turmeric Matrix with Two Other Curcumin Formulations: An Open-label Parallel-arm Study.

Curcuminoids are the major bioactive molecules in turmeric, and poor bioavailability deters them from being the major components of many health and wellness applications. This study was conducted to assess the bioavailability of a completely natural turmeric matrix formulation (CNTMF) and compare its bioavailability with two other commercially available formulations, namely, curcumin with volatile oil (volatile oil formulation) and curcumin with phospholipids and cellulose (phospholipid formulation) in healthy human adult male subjects (15 each group) under fasting conditions. Each formulation was administrated orally as a single 500-mg dose in capsule form, and blood samples were analyzed by liquid chromatography mass spectrometry at various time intervals up to 24 h.

Intraoperative diagnosis of glioblastomamultiforme with oligodendroglial and sarcomatous components.

Glioblastoma, the most frequent primary brain tumor and the most malignant neoplasm, can have the most heterogeneous morphological presentation. Along with classical morphological features, areas of oligodendroglial component and mesenchymal differentiation may be seen. The present case was a rare case of glioblastoma presenting with sarcomatous and oligodendroglial components.

Middle cerebral artery infarct following multiple bee stings.

Neurologic events following bee stings are very rare. We report a 59-year-old man who became drowsy with slurred speech following multiple bee stings. In the hospital, he was found to have left-sided hemplegia, seventh cranial nerve palsy, and left conjugate gaze palsy.
