STOCKHOLM, Sweden: Researchers at Karolinska Institutet and Danderyd Hospital have studied the risk of additional myocardial infarctions and early death in severely obese patients who underwent metabolic surgery following a myocardial event. The registry study, which included 1,018 individuals, showed a lower risk of additional myocardial infarctions and an improved survival rate that cannot be attributed solely to weight loss.
GOTHENBURG, Sweden: Large cranial reconstructions are being increasingly performed worldwide, but remain a substantial clinical challenge. Researchers from Sahlgrenska Academy at the University of Gothenburg, in cooperation with Karolinska Institutet in Stockholm and Uppsala University, have now developed a novel bioceramic implant. Study results show that it has been proved to stimulate regeneration of natural skull bone so that even large cranial defects can be repaired in a way which was previously not possible.
GOTHENBURG, Sweden: On average, patients who have undergone bariatric surgery live longer than those given conventional treatments, a recent study has shown. Compared with the general population, however, both groups’ excess mortality is high. The study results are based on the Swedish Obese Subjects (SOS) study, which started in 1987 and is led by Sahlgrenska Academy at the University of Gothenburg.
BIRMINGHAM, UK: For fear that patients may contract COVID-19 in hospitals, millions of operations around the world were cancelled during the first wave of the pandemic. If operations for cancer and other time-dependent diseases are delayed, they may progress to be untreatable. Setting up COVID-19 free hospital areas for surgical patients could save lives during the second wave of the pandemic, a new global study has revealed.
GOTHENBURG, Sweden: In general, surgeons who perform numerous cataract operations each year encounter relatively few severe cases, which probably contributes to their lower complication rate, as shown by a study led by the University of Gothenburg. The study results have provided new evidence in the endeavour to further improve patient care.
KLAGENFURT, Austria: An important sub-area of minimally invasive surgery is interventional radiology. At present, robotic systems are only used to hold and position surgical instruments. A research project, led by the Alpen-Adria-Universität Klagenfurt, will now explore more advantages of surgical robots and increase their autonomy to support surgeons.
BERLIN, Germany: Using highly complex analytical techniques, researchers from Charité – Universitätsmedizin Berlin have been able to observe how different metals were released from joint implants and accumulated in the surrounding bone tissue. Contrary to previous assumptions, a constant release of metals from various implant components occurred independently of mechanical stress. The study findings will help to optimise the materials used in implants and enhance their safety.
ZURICH, Switzerland: The International Society of Surgery (ISS) has decided to postpone the International Surgical Week (ISW) by one year. The biannual meeting, which provides an educational platform for surgeons, trainees and students from around the world, will now take place from 28 August to 1 September 2022 in Kuala Lumpur in Malaysia.
GRAZ, Austria: Of 790 patients currently waiting for a donor organ in Austria, approximately three quarters need a new kidney, followed by patients in need of a liver. Particularly in the latter case, the organ quality of the available liver decreases with increasing donor age. To enable a faster and more comprehensive assessment of the organ quality needed for transplantation, researchers at the University of Graz and the Medical University of Graz are working together to develop a new imaging process, using the liver as test model.
GOTHENBURG, Sweden: A doctoral thesis at Sahlgrenska Academy at the University of Gothenburg has shown that the results of primary hip replacement surgery improve the more often a surgeon performs this operation annually. However, it did not make a significant difference whether the operating surgeon was a fully trained specialist in orthopaedics or a resident physician being trained as an orthopaedic specialist. The results may help to improve the quality for patients undergoing a hip replacement operation.
HALLE (SAALE), Germany: The use of medical implants can be hampered by chronic inflammatory reactions, which may result in failure of the device. Now, researchers at Martin Luther University Halle-Wittenberg (MLU) have developed a new method of applying anti-inflammatory substances to implants in order to inhibit undesirable inflammatory reactions in the body.
DÜBENDORF, Switzerland: Researchers of the Swiss Federal Laboratories for Materials Science and Technology (Empa) and the Swiss Federal Institute of Technology in Lausanne (EPFL) have jointly developed a fully transparent surgical mask that is intended to replace the three-layer mask normally worn by medical staff. The mask was developed primarily with the aim of improving non-verbal communication between nursing staff and patients but could also be worn by dentists to protect against transmission of bacteria and viruses, such as SARS-CoV-2. The product is expected to be launched in early 2021.
DAVOS, Switzerland: An international cross-sectional survey has found that most surgeons believed that the supply of personal protective equipment (PPE) to front-line healthcare workers by hospitals in the first month of the SARS-CoV-2 outbreak was inadequate.
HALLE (SAALE), Germany: Pharmacists at Martin Luther University Halle-Wittenberg (MLU), in cooperation with neurosurgeons at university hospital Halle (Saale), have developed a new method that allows direct application of the drug nimodipine in the brain with fewer side effects. The drug may prevent nerve cells from dying after brain surgery.
LONDON, UK: Bariatric and metabolic surgery, used to treat Type 2 diabetes and obesity, has been suspended during the COVID-19 pandemic in order to free up inpatient capacity and reduce the risks of infection among patients and staff. However, in a recent paper, experts from the Diabetes Surgery Summit (DSS), an international consensus conference series, have warned that the backlog of operations could increase risks of morbidity and mortality for patients awaiting surgery.
In order to provide an alternative implant solution for those patients with poor medical preconditions, Prof. Nils-Claudius Gellrich, director of the clinic for oral and maxillofacial surgery at the Hannover Medical School in Germany, and Dr Björn Rahlf, senior physician for oral surgery at the same clinic, designed the IPS (individual patient solution) Implants Preprosthetic. In conversation with Dental Tribune International, Gellrich and Rahlf spoke about the patients for whom it is suitable and how they developed this individual implant.
LEEDS, UK: In a recently published consensus statement, leading cancer experts have discussed radiotherapy treatment options for rectal cancer during the COVID-19-pandemic. In their paper, they recommended a one-week course of radiotherapy and to delay surgery for patients with bowel cancer.
LONDON, UK: Since the outbreak of SARS-CoV-2 there have been speculations that the intake of non-steroidal anti-inflammatory drugs (NSAIDs) could worsen the course of COVID-19. However, a recent study conducted by researchers from King’s College London and Guy’s and St. Thomas NHS Foundation Trust (GSTT), has found that there is neither evidence for nor against the use of NSAIDs such as ibuprofen for patients infected with COVID-19.
