Hygiene monitoring systems for hospital textile laundering
Sabina Fijan, Sonja Šostar-Turk, 2007, strokovni članek

Opis: The main aim of washing laundry is to remove soils and microorganisms from infected and dirty textiles and achieve clean, fresh and disinfected textiles ready for use. Textiles undergo laundering processes, which include: soil removal with special laundering agents; bleaching; disinfecting; and finally neutralising and rinsing. Because textiles from hospitals may contain many kinds of pathogenic -bacteria, fungi and viruses, it is essential that the laundering process has not only a cleaning effect but also an antimicrobial one. Since users of hospital textiles are often patients with a weakened immune -system, it is recommended that best practice and common sense be employed when washing and -disinfecting hospital textiles. Most people assume that the laundry returned to them is in fact clean and, therefore, safe. Experience encourages all infection control teams to take laundering very seriously. (1-15) Inappropriately disinfected textiles are one of the possible sources of nosocomial infections for patients. There are reports of hospital textiles being the source of nosocomial infection with streptococci, enterococci, Bacillus cereus, staphylococci and coliforms.(5-9) There are some documented cases where staff in hospital wards and laundries have been infected with scabies, fungi, salmonellas, gastroenteritis viruses, hepatitis A viruses and coxiellas after treating dirty laundry.

Implementing hygiene monitoring systems in hospital laundries in order to reduce microbial contamination of hospital textiles
Sabina Fijan, Sonja Šostar-Turk, Avrelija Cencič, 2005, izvirni znanstveni članek

Opis: As textiles sent to hospital laundries contain many types of pathogenic organisms, it is important that laundering not only has an appropriate cleaning effect but also has a satisfactory disinfecting effect. Critical to this process is the maintenance of an appropriate hygiene level in the clean area of laundries in order to prevent recontamination of textiles from manual handling when ironing, folding, packing etc. The aims of this study were to evaluate the hygienic state of a hospital laundry, to introduce continuous sanitary measures, and to introduce a continuous hygiene monitoring system with an infection control programme. Two systems for evaluating hospital laundry hygiene were combined: HACCP principles (hazard analysis and critical control points) and RAL-GZ 992 standards (quality assurance standard for textile care of hospital laundry). Evaluation of the hygienic state of the hospital laundry was carried out by evaluating the number and types of micro-organisms present at the critical control points throughout the whole laundering process, using RODAC agar plates for surface sampling and the pour plate method for investigating water samples. The initial examination showed that the sanitary condition of the laundry did not reach the required hygiene level. Therefore, fundamental sanitation measures were instituted and the examination was repeated. Results were then satisfactory. The most important critical control point was the chemothermal laundering efficiency of the laundering process. To prevent micro-organisms spreading into the entire cleanworking area, it is important that, in addition to regular sanitary measures such as cleaning/disinfecting all working areas, technical equipment and storage shelves etc., regular education sessions for laundry employees on proper hand hygiene is undertaken and effective separation of the clean and dirty working areas is achieved.

Muscular-skeletal diseases require scientifically designed sewing workstations
Andrej Polajnar, Marjan Leber, Nataša Vujica-Herzog, 2010, izvirni znanstveni članek

Opis: The paper describes the adjustment of the sewing workstation with respect to working postures and workers' perceptions based on the results of a survey research carried out in 32 sewing workstations in different garment production factories in Slovenia. Poor posture of the trunk, neck and upper extremities, and the monotonous repetitive movements result in a high prevalence of musculoskeletal complaints affecting back, neck and upper extremities among sewing machine operators. Several studies have confirmed that working postures are still a common problem in garment industry and ergonomically designed workstations can considerably reduce the above-mentioned problems. Therefore, the main purpose of the paper is to formulate all ergonomic recommendations for the modification of sewing machineworkstations.

Rotaviral RNA found on various surfaces in a hospital laundry
Sabina Fijan, Andrej Steyer, Mateja Poljšak-Prijatelj, Avrelija Cencič, Sonja Šostar-Turk, Srečko Koren, 2008, izvirni znanstveni članek

Opis: The aim of this investigative study was to determine the presence of rotaviral RNA at various control points (CP) of a hospital laundry. One of the possible sources of hospital infections is inappropriately laundered and disinfected hospital textiles. RT-PCR and nested PCR for gene amplification using specific primers following RNA isolation were used to determine the presence of rotaviral RNA on swabs. In addition, rotavirus suspensions were inoculated on marked surfaces as positive controls for different surfaces (cotton textiles, folding table and industrial dryer). Rotaviral RNA was found on various laundry surfaces: technical equipment, storage shelves, transport vehicles, personnel's hands, damp textiles, and folded laundry. Rotaviral RNA was also detected at all positive controls on tested surfaces after 24 h. Based on the results, it is very important to take into consideration the proper handling of textiles after washing as one of the precautions against hospital-acquired infections. This paper reports the presence of rotaviral RNA for the first time on surfaces in laundries and equipment, as well as textiles.

Antimicrobial disinfection effect of a laundering procedure for hospital textiles against various indicator bacteria and fungi using different substrates for simulating human excrements
Sabina Fijan, Srečko Koren, Avrelija Cencič, Sonja Šostar-Turk, 2007, izvirni znanstveni članek

Opis: Recent studies confirm the increase of nosocomial infections and microbial resistance. One of the possible causes is infected textiles due to inappropriate laundering procedures. Most Slovenian laundries use thermal laundering procedures with high energy and water consumption to disinfect hospital textiles. In addition to this fact, there is an increasing number of hospital textiles composed of cotton/polyester blends that cannot endure high temperatures of thermal disinfection. On the other hand, decreasing the temperature of laundering procedures enhances the possibility of pathogenic microorganisms to survive the laundering procedure. In our research, we determined the antimicrobic laundering effect by simulating a common laundering procedure for hospital textiles in the laboratory washing machine at different temperatures by the use of bioindicators. Enterococcus faecium, Staphylococcus aureus, Mycobacterium terrae, Enterobacter aerogenes, and Pseudomonas aeruginosa were used for determining the antibacterial laundering effect. Candida albicans was used for determining the antifungal laundering effect. Swine blood, artificial sweat, and swine fat were used as substrates for simulating human excrements and were inoculated together with the chosen microorganisms onto cotton pieces to simulate real laundering conditions. It was found that E. faecium, S. aureus, E. aerogenes, and P. aeruginosa survivedat 60 °C, but no microorganisms were found at 75 °C.

The influence of physico-chemical parameters on water scale precipitation on washing machines' heaters
Danijela Doberšek, Darko Goričanec, Jurij Krope, 2007, strokovni članek

Opis: The paper presents the results of analysis of physico - chemical parameters influence on the intensity of water scale precipitation on washing machines heaters. Washing machines of the same producer were, to this end, modified to an endless cycle of washing with the same amount of cotton fabric at the same conditions. On the basis of various experiments it was determined that water hardness, the amount of exceeded carbon dioxide, water turbulence around the heater, the amount of cotton fibres in water exceeded from fabrics, and heater specific heat strength have the key role in water scale building up in washing machines heaters.

Platelet-rich plasma, especially when combined with a TGF-ß inhibitor promotes proliferation, viability and myogenic differentiation of myoblasts in vitro
Robi Kelc, Martin Trapečar, Lidija Gradišnik, Marjan Rupnik, Matjaž Vogrin, 2015, izvirni znanstveni članek

Opis: Regeneration of skeletal muscle after injury is limited by scar formation, slow healing time and a high recurrence rate. A therapy based on platelet-rich plasma (PRP) has become a promising lead for tendon and ligament injuries in recent years, however concerns have been raised that PRP-derived TGF-β could contribute to fibrotic remodelling in skeletal muscle after injury. Due to the lack of scientific grounds for a PRP -based muscle regeneration therapy, we have designed a study using human myogenic progenitors and evaluated the potential of PRP alone and in combination with decorin (a TGF-β inhibitor), to alter myoblast proliferation, metabolic activity, cytokine profile and expression of myogenic regulatory factors (MRFs). Advanced imaging multicolor single-cell analysis enabled us to create a valuable picture on the ratio of quiescent, activated and terminally committed myoblasts in treated versus control cell populations. Finally high-resolution confocal microscopy validated the potential of PRP and decorin to stimulate the formation of polynucleated myotubules. PRP was shown to down-regulate fibrotic cytokines, increase cell viability and proliferation, enhance the expression of MRFs, and contribute to a significant myogenic shift during differentiation. When combined with decorin further synergistc effects were identified. These results suggest that PRP could not only prevent fibrosis but could also stimulate muscle commitment, especially when combined with a TGF-β inhibitor.
