Background: Staphylococcus aureus is one of the species of bacteria most frequently isolated from medical devices. The ability to produce biofilm is an important step in the pathogenesis of these staphylococci infection, and biofilm formation is strongly dependent on environmental conditions as well as antibiotics and disinfectants used in the treatment and prevention of infections.Methodology: In this study, 28 S. aureus isolated from medical devices at the University Hospital Center of Sidi Bel Abbes in Northwestern Algeria were tested for biofilm formation by culture on Red Congo Agar (RCA). The tube method (TM) and tissue culture plate (TCP) techniques were also used to investigate the effect of penicillin, ethanol and betadine on pre-formed biofilm.Results: Nineteen S. aureus isolates produced biofilm on the RCA and 7 produced biofilms by the tube method, 2 of which were high producer. In addition, 9 S. aureus isolates produced biofilm on polystyrene micro-plates, and in the presence of penicillin and ethanol, this number increased to 19 and 11 biofilm producing S. aureus isolates respectively. On the other hand, no biofilm was formed in the presence of betadine.Conclusion: It is important to test for biofilm formation following an imposed external constraint such as disinfectants and antibiotics in order to develop new strategies to combat bacterial biofilms but also to better control their formation. Keywords : Staphylococcus aureus, biofilm, medical device, disinfectant, antibiotic French Title: Effets de certains désinfectants et antibiotiques sur la formation de biofilms par Staphylococcus aureus isolé à partir de dispositifs médicaux au Centre Hospitalier Universitaire de Sidi Bel Abbès, Algérie Contexte: Staphylococcus aureus est l'une des espèces de bactéries les plus fréquemment isolées des dispositifs médicaux. La capacité de produire du biofilm est une étape importante dans la pathogenèse de ces infections à staphylocoques, et la formation de biofilm dépend fortement des conditions environnementales ainsi que des antibiotiques et des désinfectants utilisés dans le traitement et la prévention des infections. Méthodologie: Dans cette étude, 28 S. aureus isolés à partir de dispositifs médicaux au Centre hospitalier universitaire de Sidi Bel Abbès dans le nord-ouest de l'Algérie ont été testés pour la formation de biofilm par culture sur gélose rouge du Congo (RCA). La méthode des tubes (TM) et les techniques de plaques de culture tissulaire (TCP) ont également été utilisées pour étudier l'effet de la pénicilline, de l'éthanol et de la bétadine sur le biofilm préformé. Résultats: Dix-neuf isolats de S. aureus ont produit un biofilm sur le RCA et 7 ont produit des biofilms par la méthode des tubes, dont 2 étaient très productifs. De plus, 9 isolats de S. aureus ont produit du biofilm sur des microplaques en polystyrène, et en présence de pénicilline et d'éthanol, ce nombre est passé à 19 et 11 isolats de S. aureus producteurs de biofilm respectivement. En revanche, aucun biofilm ne s'est formé en présence de bétadine. Conclusion: Il est important de tester la formation de biofilm suite à une contrainte externe imposée comme les désinfectants et les antibiotiques afin de développer de nouvelles stratégies pour lutter contre les biofilms bactériens mais aussi pour mieux contrôler leur formation.

UNSTRUCTURED Ransomware attacks, such as Conti, Ryuk, Petya, and Sodinokibi, that target medical institutions are increasing rapidly. In 2020, in the United States., ransomware attacks affected over 600 separate clinics, hospitals, and organizations, and more than 18 million patient records. The cost of these attacks is estimated to be almost $21 billion USD [1]. The first death related to ransomware attacks was reported by the University Hospital of Düsseldorf in Germany in 2020. The aim of this literature is to study vulnerabilities of cybersecurity in medical institutions, characteristics of ransomware aimed at medical institutions, and technical measures to prevent ransomware. From a security point of view, one of the most important targets of hackers against hospitals is medical devices. Many medical devices in hospitals are equipped with outdated software that is vulnerable to security and have many restrictions on security patches/updates. In addition, it is not easy to install even security functions such as antivirus due to the specificity of medical devices where availability is most important. As introduced in the Medjack report issued by TrapX Labs, in many cases, attackers target medical devices that are relatively insecure and then penetrate deep into more critical network infrastructure, such as EMR servers [2]. In this literature, we discuss various considerations to respond to ransomware while ensuring the availability of medical devices, and present AI-MDIPS (AI-based medical device intrusion prevention system) technology, a non-invasive and manageable security technology applicable to medical devices developed by the Korean government

IntroductionIn hospitals with standardized processes of health technology assessment (HTA), clinical studies are usually required to support incorporation requests. Factors such as conflicts of interest and confirmation bias affect the quality of the evidence. The objective of this study was to assess the quality of studies submitted to the university hospital to support the incorporation of non-drugs technologies.MethodsAll submissions received from 2017 to 2019 were reviewed. Data about methodological quality of studies sent by requesters and their utilization of final recommendation were collected, as well as about studies retrieved during additional search performed by HTA. The Jadad and Assessing the Methodological Quality of Systematic Reviews (AMSTAR) scales were used for assessing the quality of randomized clinical trials (RCTs) and systematic reviews (SRs), respectively.ResultsTwenty-one requests for incorporation of equipment were analyzed. The average number of studies attached was 4.5. In eight requests (53.3%), both SRs and RCTs were attached. In seven (46.7%) only low quality studies were included were included; additional search identified RCTs and SRs in four of these cases. According to the Jadad and AMSTAR scales, 60 percent of the submitted RCTs showed a high risk of bias, while 57 percent of the SRs showed moderate quality, respectively.ConclusionsThe best evidence is not always submitted during the incorporation request process. Requirements for studies of moderate-to-high quality to accept the incorporation demand could be helpful to avoid inefficiencies in hospital-based HTA.
