1. 1. The functional anatomy of the crocodilian heart

   Kandidat-uppsats, Linköpings universitet/Biologi

   Författare :Jennifer Karlsson; [2023]
   Nyckelord :Anatomy; Cardiac right-to-left shunt; Cog-teeth-like valves; Crocodilian heart; Foramen of Panizza; Hemodynamics; Left aorta;

   Sammanfattning : Crocodiles are ectothermic, intermittent breathing reptiles with low metabolic rates. Additionally, they are diving animals that can stay submerged for long periods, which poses special demands on their cardiovascular system. The crocodilian heart is four-chambered with completely separated ventricles, making it unique among other reptiles. LÄS MER

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

   Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

   Författare :Frida Hermansson; [2023]
   Nyckelord :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;

   Sammanfattning : 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).

4. 3. Omvårdnadsåtgärder som minskar risken för perifera nervskador : En systematiskt utförd litteraturstudie

   Magister-uppsats, Högskolan i Gävle/Med-Vårdvetenskap

   Författare :Pernilla Ingvarsson; Maria Jonsson; [2023]
   Nyckelord :omvårdnadsåtgärder; perifera nervskador; positionering; SSEP;

   Sammanfattning : Sammanfattning   Bakgrund Nervskador associerade med positionering förekommer, men incidensen är oklar. Vid generell anestesi tas patientens fysiska förmåga att skydda sig själv mot smärta bort. Utan denna respons så är patienten predisponerad för nervskador. Nervskador ses vanligen i samband med oförsiktig patientspositionering. LÄS MER

5. 4. 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?

   Master-uppsats, Örebro universitet/Institutionen för hälsovetenskaper

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

   Sammanfattning : 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). LÄS MER

7. 5. Identification of epigenetic biomarkers associated with the development of diabetic kidney disease in individuals with type 2 diabetes: a nested cohort study

   Master-uppsats, Lunds universitet/Socialmedicin och global hälsa

   Författare :Marian Paiva Marchiori; [2023]
   Nyckelord :Medicine and Health Sciences;

   Sammanfattning : Introduction. Type 2 diabetes (T2D) is the most common type of diabetes, and it can cause complications such as diabetic kidney disease (DKD), the main cause of end-stage renal disease worldwide. There is an urgent need to develop new biomarkers that would improve DKD’s risk prediction in patients with T2D. LÄS MER
