The cesarean section rate in Romania is among the top three in Europe and that it is among the top ranked in the world. Robson classification is a particularly useful tool for all factors involved in obstetrics. In our study, 840 cesarean births from 2018 were classified according to Robson Classification. Thus, the patients analyzed in the present study have in common an almost obvious trait: the indication for caesarean is, in mostly analyzed cases, not very clear. In fact, much of the cesareans studied are nothing but cesarean performed at the request of the patient. We believe that the urgent implementation of Robson Classification in maternity hospitals in Romania is not only necessary, but also extremely urgent, being a practical tool in determining the causes of certain obstetrical practices and customs.
The study was designed to assess the validity of a finite element analysis for predicting the behavior of cemented knee implant used in total knee arthroplasty (TKA), for different mechanical loads, and correlation with clinical outcomes of this procedure. We conducted computational simulations using finite element analysis of two situations: i) The ideal prosthetic component positioning; and ii) variable varus tibial malposition, but with a balanced knee. A total of 80 cemented TKAs performed on 70 patients were divided into two groups. Patients from one group required secondary asymmetric tibial recut for balancing the prosthetic knee and patients from the other group, did not. In regards to the results, we observed no differences upon analysis of the postoperative results of the Knee Society Score (KSS), the angle between the femur and tibia, the range of motion and frontal laxity between groups. The finite element analysis showed that in a 3˚ varus inclination of the joint interline, but with a balanced knee, the maximum contact stress, measured on the tibial plateau surface, increased by 11% compared to the value of mechanical alignment. In conclusion, analysis of the computational model using finite elements showed predictable results of cemented TKA for the different situations of mechanical loads.
Iodoform (triiodomethane), a yellow crystalline solid, belonging to the family of organic halogen compounds, is used as an antiseptic. Its antiseptic action is due to the slow release of iodine under the action of catalase from wounds. Currently, it is widely used only in dentistry and in veterinary medicine. We have extended, with good results, the use of iodoform as an antiseptic for other types of surgical or traumatic wounds that have been infected with piogens. Between 2009 and 2018, on 242 cases of different wounds, we obtained good results, with no severe adverse effects.
Bisphosphonates currently represent the main therapy in the fight against osteoporosis. This is a serious condition, with an increasing incidence, presently affecting about 12 million people in the U.S. mostly women aged over 50 years. Thus, approximately 40% -50% of them suffer an osteoporotic fracture. Bisphosphonates mechanism of action consists in reducing osteoclast-mediated bone resorption, modifying bone turn over, leading to an increase in bone density. This dramatically reduces the risk of fracture. Although bisphosphonates shows a good safety profile, lately emerged some alarm signals that link their long management to some unusual side effects. Bisphosphonates is an effective therapy to combat osteoporosis, their causal relationship with FAF production not being shown. In the absence of other evidence, it is unclear whether BF therapy is directly involved in producing FAF or only a component of a combination of factors, in reality being just an indicator of a severe degree of osteoporosis. In the same time, we must not forget that the FAF are very rare compared to the number of patients in therapy with BF and the number of typical femur fractures, and the risk / benefit ratio it is definitely in favor of the benefit.
We present our efforts in establishing a Research Pole in Photonics in the future Arad-Timisoara metropolitan area projected to unite two major cities of Western Romania. Research objectives and related training activities of various institutions and groups that are involved are presented in their evolution during the last decade. The multi-disciplinary consortium consists principally of two universities, UAVA (Aurel Vlaicu University of Arad) and UMF (Victor Babes Medicine and Pharmacy University of Timisoara), but also of the Arad County Emergency University Hospital and several innovative SMEs, such as Bioclinica S.A. (the largest array of medical analysis labs in the region) and Inteliform S.R.L. (a competitive SME focused on mechatronics and mechanical engineering). A brief survey of the individual and joint projects of these institutions is presented, together with their teaching activities at graduate and undergraduate level. The research Pole collaborates in R&D, training and education in biomedical imaging with universities in USA and Europe. Collaborative activities, mainly on Optical Coherence Tomography (OCT) projects are presented in a multidisciplinary approach that includes optomechatronics, precision mechanics and optics, dentistry, medicine, and biology.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
