1. 1. Physiology-Guided Machine Learning for Improved Reliability of Non-Invasive Assessment of Pulmonary Hypertension

   University essay from Linköpings universitet/Avdelningen för medicinsk teknik

   Author : Frida Hermansson; [2023]
   Keywords : Pulmonary Hypertension; pulmonary hypertension; improving; physiological-guided; machine learning; neural networks; NN; artificial neural networks; non-invasive; PH; tricuspid regurgitation; peak tricuspid regurgitation velocity; tricuspid regurgitation velocity; right ventricular systolic pressure; VGG16; Unet; TR-CNN; CNN; pulmonell hypertension; förbättra; fysiologisk-guidning; neurala nätverk; trikuspidal regurgitation; maximal trikuspidal regurgitation; icke-invasivt;

   Abstract : Diagnosing pulmonary hypertension (PH) with right heart catheterization (RHC) is associated with a risk for complications and high expenses, leading to late diagnoses [1]. Transthoracic echocardiography can be used to assess non-invasive indicators for PH such as right ventricular systolic pressure (RVSP), which can be estimated by combining the peak tricuspid regurgitation velocity (TRV) with the estimated right arterial pressure (RAP).

3. 2. Comparison of direct Fick's principle and thermodilution for calculating cardiac output in patients with pulmonary arterial hypertension.Does the assessment of cardiac index and pulmonary vascular resistance differ depending on which method is chosen?

   University essay from Örebro universitet/Institutionen för hälsovetenskaper

   Author : Gabriella Persson; [2023]
   Keywords : Pulmonary arterial hypertension; cardiac output; direct Fick´s principle; thermodilution;

   Abstract : Pulmonary arterial hypertension (PAH) is an uncommon but serious disease that causes increased pressure in the pulmonary vessels and increased pulmonary vascular resistance (PVR), which in turn leads to right heart failure. At diagnosis, mean pulmonary artery pressure (mPAP) must be >20 mmHg, pulmonary artery wedge pressure (PAWP) ≤15 mmHg and PVR >2 Wood units (WU). READ MORE

4. 3. Dystoki och kejsarsnitt på marsvin i Sverige : intervjustudie om svenska klinikers rutiner gällande anestesi, analgesi och kirurgiskt ingrepp

   University essay from SLU/Dept. of Clinical Sciences

   Author : Isak Svensson; [2021]
   Keywords : dystoki; kejsarsnitt; marsvin; dräktighetstoxikos; dräktighet; anestesi; analgesi;

   Abstract : Dystoki och dräktighetstoxikos är relativt vanligt förekommande problem hos marsvin förknippat med hög mortalitet både för modern och ungarna. Olika profylaktiska åtgärder och att para marsvinen innan blygdbensfogen sammanväxer är bästa sättet att förhindra dräktighetskomplikationer. READ MORE

5. 4. Health economic analysis of a urinary catheter which reduce the frequency of urinary tract infections (UTIs) Research questions: a) What is the willingness-to-pay (WTP) in Sweden - from a patient perspective - for a urinary catheter which reduce the annual frequency of urinary tract infections by 25% and 50%, respectively, and (b) is the WTP dependent on the annual frequency of UTIs and gender?

   University essay from Göteborgs universitet/Förvaltningshögskolan

   Author : Thomas Lindqvist; [2019-03-20]
   Keywords : Health Economic Analysis; Willingness to pay; Urinary catheter; Cost benefit analysis;

   Abstract : Objective: To investigate the preference for urinary catheters that can reduce the frequency of urinary tract infections (UTIs), among Swedish patients practicing clean intermittent catheterization (CIC), and analyze if the preference is affected by the frequency of UTIs and gender. Methods: The preference for a clinically more effective catheter was expressed as a monetary value by investigating the patients’ willingness-to-pay (WTP) to switch catheters. READ MORE

6. 5. Utvärdering av en semi-automatiserad ultraljudsapparat för mätning av urinvolym i blåsan, på djur

   University essay from SLU/Dept. of Clinical Sciences

   Author : Elisabeth Miller; [2017]
   Keywords : BladderScan; hund; katt; gris;

   Abstract : Urinvolymen hos sällskapsdjur är viktig att följa i klinisk verksamhet, bland annat för att se om ett djur kan producera urin vid njurskador och transplantationer. Det är även av intresse att upptäcka en distension av urinblåsan i samband med patologier där uretra inte kan relaxera eller är blockerad, då en urinblåseöverfyllnad kan orsaka stress hos djuret och i vissa fall ge livshotande skador.
