1. 11. ICU prognostication: Time to re-evaluate? Register-based studies on improving prognostication for patients admitted to the intensive care unit (ICU)

   Författare :Peder Andersson; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Intensive Care; Critical Care; Mortality; Cerebral Performance Category; Cardiac arrest; Out-of-hospital cardiac arrest; Sepsis; Lactate; Troponin; Neuron-specific enolase; Neurofilament light; Age; Elderly; Prognostication; Prediction; Scoring system; Neural net; Artificial neural network; Deep learning; Artificial intelligence;

   Sammanfattning : Background: ICU prognostication is difficult because of patients’ prior comorbidities and their varied reasons for admission. The model used for ICU prognostication in Sweden is the Simplified Acute Physiology Score 3 (SAPS 3), which uses information gathered within one hour of ICU admission to predict 30-day mortality.

3. 12. Circulatory Failure and Outcome in Out-of-Hospital Cardiac Arrest

   Författare :Joachim Düring; Lund Institutionen för kliniska vetenskaper; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cardiac Arrest; Out-of hospital cardiac arrest; Circulatory failure; Survival; Copeptin; Lactate; Temperature management;

   Sammanfattning : Circulatory failure is considered one of the entities of the post cardiac arrest syndrome contributing to poor outcome. It is reported at 15-70% of all patients successfully resuscitated from out-of-hospital cardiac arrest (OHCA). LÄS MER

4. 13. Identification of the high risk hip fracture patients

   Författare :Magnús Hjaltalín Jónsson; Anestesiologi och intensivvård; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Hip fractures; Mortality; Nottingham Hip Fracture Score; POSSUM; P-POSSUM; Biomarkers; Lactate; GDF-15; CA-125; Cystatin C; Creatinine; Shrunken Pore Syndrome;

   Sammanfattning : Background: Hip fractures are common in older individuals entailing considerable risk of morbidity and mortality. Instruments are needed to enhance risk stratification of hip fracture patients. There is limited knowledge of the role of biomarkers as risk prognosticators for mortality in hip fracture patients.

5. 14. Metabolic and Cardiovascular Responses During Variable Intensity Exercise

   Författare :Glenn Björklund; Mittuniversitetet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cross-country skiing; cycling; heart rate; lactate; O2 extraction; O2 uptake; performance; ventilation; Sports; Idrott;

   Sammanfattning : Previous research investigating endurance sports from a physiological perspectivehas mainly used constant or graded exercise protocols, although the nature ofsports like cross-country skiing and road cycling leads to continuous variations inworkload. Current knowledge is thus limited as regards physiological responses tovariations in exercise intensity. LÄS MER

7. 15. Retinal glucose metabolism and blood flow : Effects of photic stimulation

   Författare :Lin Wang; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; blood flow; darkness; flicker; glucose oxidation; glycolysis; lactate; light; nitric oxide; optic nerve; retina; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

   Sammanfattning : Retinal glucose metabolism was investigated under different light conditions in cats,pigs and rabbits. Glycolysis and glucose oxidation in the outer and inner parts of theretina were assessed by determining arteriovenous concentration differences foroxygen, glucose and lactate, as well as local blood flow.
