Antimicrobial surface coating in the emergency department as protective technology for infection control (ASEPTIC): a pilot randomized controlled trial.

Study Objective: We examined the effectiveness of an antimicrobial surface coating for continual disinfection of high touch-frequency surfaces in the emergency department (ED).

Methods: Following a preliminary observation identifying stretcher rails as the surface with highest touch-frequency in the ED, we conducted a pilot randomized controlled trial involving 96 stretcher rails. The stretchers were randomized to receive an antimicrobial surface coating or placebo coating.

Consumer habits and practices for cosmetics and personal care products in Singapore: An online survey.

Understanding trends in habits and practices of cosmetics and personal care products is essential for the assessment of product exposure and simultaneously, the establishment of safe use levels for incorporated ingredients. To date, most exposure data is limited to European and USA populations, with data on Asian-specific habits and practices lacking. This data gap needs to be filled as evidence has shown that there is a large variation in product use behaviors between consumers, across and within populations.

Could it be groove pancreatitis? A frequently misdiagnosed condition with a surgical solution.

Background: Groove pancreatitis (GP) is an underrecognised subtype of chronic pancreatitis, focally affecting the area between the duodenum and pancreatic head. It most commonly affects males between 40 and 50 years of age with a history of alcohol misuse. Patients most commonly complain of abdominal pain and vomiting.

Closed loop large bowel obstruction due to appendiceal signet cell carcinoma.

Signet cell carcinoma of the appendix is the rarest and the most aggressive subtype of appendiceal malignancy, typically presenting with non-specific symptoms. We describe a case of a 62-year-old male with large bowel obstruction, with computed tomography demonstrating dilated large bowels from caecum to proximal sigmoid colon and pneumoperitoneum. Intraoperatively, closed loop obstruction caused by dense adherence of sigmoid colon to caecum was noted, which had resulted in caecal perforation.

Emphysematous Pyelonephritis Complicated by Necrotising Fasciitis and Massive Pulmonary Embolus: A Regional Australian Experience.

A 39-year-old female presented to a regional Australian hospital with diabetic ketoacidosis. Urine microscopy, culture and sensitivity (MCS) on arrival revealed 500 leukocytes and eventually culture grew pansensitive E. coli.

Infiltrating the Curriculum: Integrating Medical History with Existing Surgical Pathology Tutorials.

This article was migrated. The article was marked as recommended. To assess medical students' perspective on medical history embedded into a pre-existing learning module.

Effect of exercise prehabilitation on functional status of patients undergoing bowel resection: a systematic review.

Background: Bowel resections have high morbidity and mortality rates and are becoming increasingly common in Australia. To reduce the burden on patients and the health system, measures for improving patient outcomes after resection must be investigated. One possible method for improving patient outcomes is prehabilitation with exercise.

Near Infrared Fluorophore-Tagged Chloroquine in Diagnostic Imaging.

Chloroquine was among the first of several effective drug treatments against malaria until the onset of chloroquine resistance. In light of diminished clinical efficacy of chloroquine as an antimalarial therapeutic, there is potential in efforts to adapt chloroquine for other clinical applications, such as in combination therapies and in diagnostics. In this context, we designed and synthesized a novel asymmetrical squaraine dye coupled with chloroquine (SQR1-CQ).

Differential regulation of proinflammatory cytokine expression by mitogen-activated protein kinases in macrophages in response to intestinal parasite infection.

Blastocystis is a common enteric protistan parasite that can cause acute, as well as chronic, infection and is associated with irritable bowel syndrome (IBS). However, the pathogenic status of Blastocystis infection remains unclear. In this study, we found that Blastocystis antigens induced abundant expression of proinflammatory cytokines, including interleukin 1β (IL-1β), IL-6, and tumor necrosis factor alpha (TNF-α), in mouse intestinal explants, in mouse colitis colon, and in macrophages.

Strain-dependent induction of human enterocyte apoptosis by blastocystis disrupts epithelial barrier and ZO-1 organization in a caspase 3- and 9-dependent manner.

Blastocystis is an emerging protistan parasite colonizing the human intestine. It is frequently reported to cause general intestinal symptoms of vomiting, diarrhea, and abdominal pain. We recently demonstrated that Blastocystis rearranged cytoskeletal proteins and induced intestinal epithelial barrier compromise.

Relationship between leisure noise exposure and otoacoustic emissions in a young Asian population.

Objective: This study compared the otoacoustic emissions amplitudes of Asian youths at risk of leisure noise exposure through the use of portable music players with their less exposed counterparts.

Design: A listening habit survey was conducted. Subjects were divided into two groups for analysis.

The music listening preferences and habits of youths in Singapore and its relation to leisure noise-induced hearing loss.

Introduction: Noise-induced hearing loss (NIHL) is a preventable condition, and much has been done to protect workers from it. However, thus far, little attention has been given to leisure NIHL. The purpose of this study is to determine the possible music listening preferences and habits among young people in Singapore that may put them at risk of developing leisure NIHL.

Pleiotropic effects of Blastocystis spp. Subtypes 4 and 7 on ligand-specific toll-like receptor signaling and NF-κB activation in a human monocyte cell line.

Blastocystis spp. is a common enteric stramenopile parasite that colonizes the colon of hosts of a diverse array of species, including humans. It has been shown to compromise intestinal epithelial cell barrier integrity and mediate the production of pro-inflammatory cytokines and chemokines.

Statin pleiotropy prevents rho kinase-mediated intestinal epithelial barrier compromise induced by Blastocystis cysteine proteases.

Blastocystis is an enteric parasite that causes acute and chronic intestinal infections, often non-responsive to conventional antibiotics. The effects of Blastocystis infections on human epithelial permeability are not known, and molecular mechanisms of Blastocystis-induced intestinal pathology remain unclear. This study was conducted to determine whether Blastocystis species alters human intestinal epithelial permeability, to assess whether these abnormalities are rho kinase (ROCK)-dependent, and to investigate the therapeutic potential of the HMG-CoA reductase inhibitor Simvastatin in altered intestinal epithelial barrier function.

Current Views on the Clinical Relevance of Blastocystis spp.

Blastocystis is an enteric protistan parasite of uncertain clinical relevance. Recent studies indicate that the parasite is a species complex and humans are potentially hosts to nine Blastocystis subtypes, most of which are zoonotic. Subtype 3 is the most common in prevalence studies, followed by subtype 1.

A rapid, high-throughput viability assay for Blastocystis spp. reveals metronidazole resistance and extensive subtype-dependent variations in drug susceptibilities.

Blastocystis is an emerging protistan parasite of controversial pathogenesis. Although metronidazole (Mz) is standard therapy for Blastocystis infections, there have been accumulating reports of treatment failure, suggesting the existence of drug-resistant isolates. Furthermore, very little is known about Blastocystis susceptibility to standard antimicrobials.
