Virus detection is highly important; the last several years, since the onset of the SARS-CoV-2 pandemic, have highlighted a weakness in the field: the need for highly specialized and complex methodology for sensitive virus detection, which also manifests as sacrifices in limits of detection made to achieve simple and rapid sensing. Surface-enhanced Raman spectroscopy (SERS) has the potential to fill this gap, and two novel approaches to the development of a detection scheme are presented in this study. First, the physical entrapment of vesicular stomatitis virus (VSV) and additional virus-like particles through substrate design to localize virus analytes into SERS hotspots is explored.

However, the development of educational video games requires expertise and, frequently, a sizable budget. Here, we report on the use of an interactive text-style video game, NanoAdventure, to communicate about sense of scale and nanotechnology to the public.

Objectives: Our objective was to assess compliance with hand hygiene over time utilizing a multifaceted approach to hand hygiene.
Background And Objective: Peripherally inserted central venous catheters (PICCs) are alternatives to short-term central venous catheters and provide intravenous access in the acute hospital setting. In this study, we describe the rate of PICC-associated bloodstream infections (BSI).
Design And Setting: Prospective cohort study using data on PICC lines reviewed from January to December 2009.
Background And Objectives: The World Health Organization (WHO) declared that pandemic influenza A (H1N1) was a public health emergency of international concern in April 2009. Herein, we describe the characteristics of patients in a Saudi Arabian hospital with and without H1N1 infection.
Methods: We reviewed the records of patients admitted with influenza-like illness and compared confirmed pandemic H1N1 cases to the H1N1-negative patients admitted to the hospital.

Clostridium difficile-associated diarrhea (CDAD) is an important healthcare-associated infection. However, there are no data from Saudi Arabia on this disease. A two-year prospective, observational study on the incidence of CDAD in a hospital in Saudi Arabia was carried out.

It is known that the activity of the 26S proteasome is important for nuclear receptor-activated gene transcription. However, the molecular mechanism by which the 26S proteasome participates in this process is not well understood.

In addition, VAP prolongs time spent on the ventilator, length of intensive care unit (ICU) stay, and length of hospital stay.
Methods: In this study, we implemented VAP bundle to decrease the rate of VAP infection.
Objective: To determine the trend of health care associated blood stream infection (HA-BSI) at Saudi Aramco Medical Services Organization.
Methods: This prospective survey was conducted during the year 2002-2006. Definitions of HA-BSI infections were based on the Centers for Disease Control and Prevention categories.
Background: The compliance with influenza vaccination among health-care workers (HCWs) is known to be low. A multi-nationality survey to explore the reasons for such poor compliance has not been studied in depth.
Materials And Methods: An epidemiologic survey to evaluate the compliance rates with influenza vaccination and possible associated reasons for compliance.
Objective: The aim of the study was to evaluate the trends of antimicrobial resistance of Enterobacter spp. over time in a Saudi Arabian hospital.
Materials And Methods: This is an in vitro surveillance study of the antibiotic susceptibility pattern among Enterobacter spp.
Objectives: The objective of this study was to examine the prevalence and trends of drug resistance of Mycobacterium tuberculosis at the Saudi Aramco Medical Services Organization.
Methods: We retrospectively identified M tuberculosis isolates from January 1989 to December 2003. Antimicrobial susceptibility and clinical data were collected and analyzed.
