Background: There is a lack of high-quality evidence to support the recommendation of an instrument to screen emergency department patients for their risk for violence.

Objective: To demonstrate the content and predictive validity and reliability of the novel Risk for Violence Screening Tool to identify patients at risk for violence.

Design And Setting: This retrospective risk screening study was conducted at a 100-bed emergency department in an urban, academic, safety net trauma center in Southern California.

Background: Globally, healthcare institutions have seen a marked rise in workplace violence (WPV), especially since the Covid-19 pandemic began, affecting primarily acute care and emergency departments (EDs). At the University Health Network (UHN) in Toronto, Canada, WPV incidents in EDs jumped 169% from 0.43 to 1.

Article Synopsis
  • The catalytic reduction of p-nitrophenol (4-NP) to p-aminophenol (4-AP) is essential in the pharmaceutical and agrochemical sectors, with sustainable methods being a priority.
  • Using manganese dioxide (MnO) supported silver (Ag) nanoparticles (NPs) as a catalyst for the catalytic transfer hydrogenation (CTH) of 4-NP with formaldehyde (HCHO) provides a safer and more efficient alternative due to lower toxicity and easy handling.
  • The study shows that electron transfer from Ag to MnO enhances HCHO activation, resulting in a more effective CTH process, with the optimized 15% Ag/MnO catalyst achieving a significant turnover frequency of 3.83

Cardiology, a high-acuity medical specialty, has traditionally emphasised technical expertise, often overshadowing the critical role of non-technical skills (NTS). This imbalance stems from the historical focus on procedural competence and clinical knowledge in cardiology training and practice, leaving a significant gap in the development of crucial interpersonal and cognitive abilities. However, emerging evidence highlights the significant impact of NTS on patient outcomes, team dynamics, and overall healthcare efficiency.

Background: The metal oxide nanoparticles possess unique properties such as biological compatibility, superior reactivity, and capacity to develop reactive oxygen species, due to this they have drawn significant interest in cancer treatment. The various MONPs such as cerium oxide, Copper oxide, Iron oxide, Titanium dioxide, and Zinc oxide have been investigated for several types of cancers including brain, breast, cervical, colon, leukemia, liver, lung, melanoma, ovarian, and prostate cancers. However, traditional physiochemical synthetic methods for MONPs commonly include toxic materials, a major concern that raises questions regarding their biocompatibility and safety.
