Four Steps to Clean Hospitals: Look; Plan; Clean; and Dry.

Now that cleaning and decontamination are recognised as integral to infection control, it is timely to examine the process in more detail. This is because cleaning practices vary widely within healthcare districts and it is likely that both time and energy are needlessly wasted with ill-defined duties. Furthermore, inadequate cleaning will not reduce the infection risk but may even enhance it. The process would benefit from a systematic appraisal, with each component placed within an evidence-based and orde...


Surgical instruments complex design as barrier for cleaning effectiveness, favouring biofilm formation.

Determine the cumulative effect of 20 cycles of contamination, cleaning (manual or manual followed by automated) and steam sterilisation on high-complex-design reusable surgical instruments (RSI) used for orthopaedic surgery.

A novel one-step lens cleaning device using air and water flow for endoscopic surgery.

In a surgical operation requiring endoscopy, it is essential to obtain a clear endoscopic view. However, it is often disturbed by the contamination on the lens during the surgery. No device can clean the lens surface simply and completely. Many surgeons are hampered by the impaired view and the distraction by the repeated cleaning of the lens. Therefore, we developed a novel endoscope cleaning device to address this problem. The device was made of 3D-printed rubber-like plastic. It contains a syringe filled...


Increased Detection Of Carbapenemase-Producing Enterobacteriaceae On Post-Clean Sampling Of Burns Units Wet Surfaces.

Wet surface biofilms are a potential reservoir for multidrug-resistant Gram-negative organisms, including carbapenamase-producing Enterobacteriaceae (CPE). Recognition of environmental sources is important in reducing secondary patient transmission. We report the increased detection of bla-IMP-4+ CPE in environmental samples from floor drains in Burns Unit shower rooms, when collected following cleaning as compared to pre-cleaning. We propose that disruption of biofilms during cleaning may account for the i...

Development of an industrial ultrasonic cleaning tank based on harmonic response analysis.

A small industrial ultrasonic cleaning tank, which is one of the best-selling models, had cleaning problems. Customers sometimes complained that the tank did not completely clean all objects, or that some objects got damaged, so a solution to the problem was urgently needed. The tank has a volume of 18 L, frequency of 28 kHz, eight horn style PZT4 transducers, and a total electric power of 400 W. The cleaning occurs from the cavitation effect which corresponds to an increase in the acoustic pressure. ...

Pillars or Pancakes? Self-cleaning surfaces without coating.

Surfaces that stay clean when immersed in water are important for an enormous range of applications from ships and buildings to marine, medical and other equipment. Up till now the main strategy for designing self-cleaning surfaces has been to combine hydrophilic/hydrophobic coatings with high aspect ratio structuring (typically micron scale pillars) to trap a (semi-)static water/air layer for drag and adhesion reduction. However, such coating and structuring can distort optical properties; get damaged in h...

In situ biofilm removal from air cathodes in microbial fuel cells treating domestic wastewater.

One challenge in using microbial fuel cells (MFCs) for wastewater treatment is the reduction in performance over time due to cathode fouling. An in-situ technique was developed to clean air cathodes using magnets on either side of the electrode, with the air-side magnet moved to clean the water-side magnet by scraping off the biofilm. The power output of the magnet-cleaned cathodes after one month of operation was 132 ± 7 mW m, which was 42% higher than the controls with no magnet (93 ± 4 mW...

How clean is your house? A study of house dust mites, allergens and other contents of dust samples collected from households.

Household dust contains an array of constituents, including house dust mites (HDM) and the HDM allergen, Der p 1, which can cause sensitivities such as asthma and eczema. Vacuuming can help alleviate symptoms, yet little is understood about cleaning behaviour in different households. This pilot study investigated the contents of dust from four household types (students; over 65 s; and families with and without pets). This was then related to cleaning behaviours and perceptions of cleanliness. Our investiga...

Cleaning agent occupational asthma in the West Midlands, UK: 2000-16.

Cleaning agents are now a common cause of occupational asthma (OA) worldwide. Irritant airway and sensitization mechanisms are implicated for a variety of old and new agents.

Alkyd resin based hydrophilic self-cleaning surface with self-refreshing behaviour as single step durable coating.

Herein, we reported the photo-catalytic degradation/anti-bacterial property of Ag-doped ZnO nanoparticles (SDZO Nps) prepared by a facile gel-combustion technique and its self-cleaning/self-refreshing/self-disinfectant behaviour while on impregnating as pigment into the alkyd resin based coating. The influence of doping Ag (1% & 2%) with ZnO has been evaluated in terms of crystal structure, morphology, optical properties, etc. using X-ray diffraction analysis, Field Emission Scanning Electron Microscope, UV...

Nonlinear polarization dynamics of Kerr beam self-cleaning in a graded-index multimode optical fiber.

We experimentally study polarization dynamics of Kerr beam self-cleaning in a graded-index multimode optical fiber. We show that spatial beam cleaning is accompanied by nonlinear polarization rotation and a significant increase of the degree of linear polarization.

Effect of cleaning protocols on bond strength of etch-and-rinse adhesive system to dentin.

This study aimed to evaluate the cleaning protocol of dentin impregnated with epoxy resin-based sealer (AH Plus) and the effects on the adhesive interface using 95% ethanol (E) or formamide solution (F) associated with microabrasion with glass microparticles (M).

Optimizing seed processing techniques to improve germination and sowability of native grasses for ecological restoration.

Grasslands across the globe are undergoing expansive degradation due to human impacts and climate change. If restoration of degraded native grassland is to be achieved at the scale now required, cost effective means for seed-based establishment of grass species is crucial. However, grass seeds present numerous challenges associated with handling and germination performance that must be overcome to improve the efficiency of seeding. Previous research has demonstrated that complete removal of the palea and le...

Work-related asthma from cleaning agents versus other agents.

Cleaning agents have been commonly implicated as causative or triggering factors in work-related asthma (WRA), mainly from epidemiologic studies. Relatively few clinical series have been reported.

Efficacy of four cleaning solutions for the decontamination of selected cytotoxic drugs on the different surfaces of an automated compounding system.

The automated aseptic preparation of ready-to-administer antineoplastic drug solutions with robotic systems reduces the risk of occupational exposure. However, the surfaces in the preparation area of the robot are to be cleaned by wiping with an appropriate cleaning solution. The aim of the study was to evaluate the cleaning efficacy of four cleaning solutions on four surface materials installed in the APOTECAchemo robot. Predefined amounts of cisplatin (Cis), 5-fluorouracil (5-FU) and cyclophosphamide (CP)...

Tough Reversible Adhesion Properties of a Dry Self-cleaning Biomimetic Surface.

Geckos have one of the world's most efficient reversible adhesion systems. Even walking in dusty conditions, geckos can dislodge up to 80% of contaminants and recover their adhesion capability after walking as few as 4 steps. Thus far, artificial dry self-cleaning materials inspired by the gecko's hierarchical fibrillar structure have been only able to remove 55% of collected large particle contaminants with 30 steps. Challenges including low mechanical strength, low stiffness, and short fatigue time keep t...

Efficiencies and mechanisms of chemical cleaning agents for nanofiltration membranes used in produced wastewater desalination.

A spiral-wound nanofiltration (NF) membrane module harvested from a full-scale produced wastewater desalination plant was examined and cleaned to explore appropriate chemical cleaning protocols. Foulant identification and cleaning efficiency and mechanisms were investigated. For total foulants, the organic components, including anionic polyacrylamide (APAM) and crude oil, accounted for a weight percentage of 86.3%, while the remaining foulants constituted the inorganic fraction, including Na, Mg, Ca, Ba, Al...

The presence of fecal test soil protects bacteria during cleaning/disinfection.

Reusable medical devices (RMDs) must be reprocessed between uses to render them safe for each use and each patient. Cleaning used devices removes organic and inorganic soil making them either safe for reuse or ready for disinfection/sterilization depending on the device. Although cleaning is an important step in a RMD's life cycle, it is not always a priority during device design. In addition, when performing cleaning validation, it is recommended that the manufacturer takes into consideration, what the mos...

Investigation of thermal properties of graphene-coated membranes by laser irradiation to remove biofoulants.

In the present study, we take advantage of the high thermal conductivity of graphene nanomaterials to develop a filter that can be easily cleaned via laser irradiation after biofouling occurs. In this investigation, the intensity of the laser beam and the amount of graphene used for membrane coating were investigated with Bacillus subtilis to achieve the most efficient removal of biofoulants. Thermographic measurements of glass microfiber filters coated with 500 µg of graphene showed an increase in tempera...

A novel device for intracolonoscopy cleansing of inadequately prepared colonoscopy patients: a feasibility study.

 The importance of high quality preprocedural bowel preparation is widely acknowledged, but suboptimal bowel cleansing still occurs in up to 20 % of all colonoscopy patients. The aim of this study was to evaluate the performance of a novel intraprocedural cleaning device for cleaning poorly prepared colons.

Anaerobic treatment of residuals from tanks transporting food and fodder.

The anaerobic digestion of wastewater from the cleaning of tank cars transporting food and fodder was investigated in both bench and pilot scales with a single-stage, mesophilic (39 °C), completely mixed process. The promising results lead to the planning and building of a 1200-m full-scale biogas plant at TS-Clean cleaning station in Fahrbinde, Germany. Due to softened water used in the cleaning of the car tanks, the alkalinity in the digester decreased as predicted by the physicochemical model developed...

The Effect of Household Oxidizing Cleaners on Chemiluminescence of Blood Using Bluestar.

This study tests the effect of three common oxidizing cleaners on the ability of the Bluestar Forensic® presumptive test for blood to identify the presence of blood on ceramic tile after cleaning. The cleaners tested were Lysol®, OxiClean®, and Arm & Hammer®. This study also tested which cleaner was the most effective at removing blood, measured by the intensity of chemiluminescence, which was quantified using RGB values in ImageJ. A "hasty" 1-min cleaning of a blood droplet was simulated using the thre...

Occupational exposure to cytotoxic drugs: the importance of surface cleaning to prevent or minimise exposure.

Healthcare workers who prepare or administer cytotoxic agents run the risk of exposure, and the risks for health are real even at doses lower than those applied in cancer patients, because, in theory, no dose is safe. The most common and problematic route of exposure is through the skin, especially as work surfaces can remain contaminated even after cleaning. This pilot study aimed to demonstrate the importance of having an effective surface decontamination protocol by determining surface contamination with...

A test method to assess the contribution of fluid shear stress to the cleaning of reusable device surfaces.

Adequate cleaning of reusable medical devices is critical for preventing cross-infection among patients. For reusable medical devices, cleaning using mechanical brushes and detergent may not be sufficient to completely remove the infectious contaminants from the surfaces. This study evaluates the role of fluid flow-induced shear stress in the detachment and removal of contaminants from device surfaces. A stainless-steel test coupon, acting as a surrogate for a device surface, was coated with artificial clot...

Graphitic carbon nitride (g-CN) nanosheets functionalized composite membrane with self-cleaning and antibacterial performance.

Membrane fouling significantly impedes membrane performance and thus short lifespan of the membrane. Membranes that functionalized with photocatalytic activity are deemed as an effective and novel approach to settle membrane fouling. The membranes with self-cleaning and antibacterial performance were fabricated via facilely filtering g-CN nanosheets onto polyacrylonitrile (PAN) porous substrates. The g-CN nanosheets were exfoliated by acid etching and ultrasound treatment, and the exfoliated nanosheets was ...
