1. 6. Power Doppler - Principles and Potential Clinical Applications

   Författare :Anders Nilsson; PG Lindgren; Torbjörn Andersson; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Radiology; Ultrasonography; Doppler studies; Power Doppler; Volume flow; Radiologisk forskning; Radiological research; Radiologisk forskning;

   Sammanfattning : The purpose of this work was to: a) Determine whether the amount of colour in a power Doppler image is dependent on the angle between the examined vessel and the soundbeam and/or on the velocity of the flow within the vessel; b) Investigate if a dependency on flow velocity could be used for the detection of volume flow differences and c) Define clinical applications utilising the improved sensitivity to low flow of PD.In the experimental studies (study I and II) a silicon tube in a water bath was insonated, the insonation angle and the volume flow changed and the resulting images stored, transferred to a personal computer and analysed with regard to the amount of colour present in the image.

3. 7. A Novel Bone Conduction Implant System

   Författare :Hamidreza Taghavi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sound radiation; amplitude modulation; low-power systems.; bone conduction implant; feedback; bone anchored hearing aid; RF power amplifier; gain headroom; implantable transducer; wireless power and data transmission; RF power and data link;

   Sammanfattning : Bone conduction is the process by which an acoustic signal vibrates the skull bones to stimulate the cochlea. Patients with pure conductive hearing loss, mixed hearing loss, and single sided deafness are sometimes poorly rehabilitated by conventional air conduction hearing aids due to for example the functionality losses in the middle ear.

4. 8. Clinical Impact of Bloodstream Infections – Characterization, Risk factors and Outcome

   Författare :Martin Holmbom; Håkan Hanberger; Christian G. Giske; Lennart E Nilsson; Mats Fredrikson; Åse Östholm Balkhed; Ralph Peeker; Linköpings universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Bloodstream infection BSI ; Antimicrobial resistance AMR ; Extended spectrum β-lactamase ESBL ; ESBL-producing Enterobacterales; Multidrug-resistant; Urinary tract infection; Sepsis; Epidemiology; Prehospital delay; Community-acquired BSI; Hospital-acquired BSI; Community-onset BSI;

   Sammanfattning : Bloodstream infection (blood poisoning) and antibiotic resistance are increasing worldwide, and already cause the loss of millions of human lives each year. According to the World Health Organisation (WHO), bloodstream infections (BSIs) represent 20% of global mortality on a par with cardiac infarct, stroke, and major trauma. LÄS MER

5. 9. Biomaterials as carriers for bone active molecules-An approach to create off-the-shelf bone substitutes

   Författare :Deepak Raina; Lund Ortopedi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; biomaterials; Bone tissue engineering; Bone morphogenic protein-2; Zoledronic acid ZA ; calcium sulphate; Hydroxyapatite; Gelatin;

   Sammanfattning : Bone tissue is commonly transplanted during orthopedic surgeries, primarily for the management of bone defects caused by trauma or various orthopedic conditions including, but not limited to, infections and tumours. Bone grafts are a surgeon’s choice, but their associated drawbacks are paving the way for biomaterial based bone graft substitutes. LÄS MER

7. 10. Large data and machine learning in analysis, diagnostics, and clinical decision making: applications in the treatment of burn injury

   Författare :Jian Fransén; Fredrik Huss; Johan Lundin; Yvette Andersson; Andrew Lindford; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Burn wound infection; Antibiotic susceptibility; Burn mortality; Machine learning; Burns; Burn assessment; Convolutional neural network; Artificial intelligence; Intensive care; ; Plastikkirurgi; Plastic Surgery; Surgery; Kirurgi; Machine learning; Maskininlärning;

   Sammanfattning : Burn injury is a common trauma globally. Large burns require fluid resuscitation, infection control, and specialized intensive care. The size of the burn and infections caused by resistant microbes are correlated to mortality, and accurate mortality predictions are important. LÄS MER
