2. 1. On Surgery for Lumbar Spinal Stenosis

   Author : Peter Försth; Bengt Sandén; Helena Brisby; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; spinal stenosis; decompression; fusion; degenerative spondylolisthesis; Orthopaedics; Ortopedi; Neurosurgery; Neurokirurgi;

   Abstract : The incidence of lumbar spinal stenosis (LSS) is steadily rising, mostly because of a noticeably older age structure. In Sweden, LSS surgery has increased continuously over the years and is presently the most common argument to undergo spine surgery. The purpose of the surgery is to decompress the neural elements in the stenotic spinal canal. READ MORE

4. 2. Surviving under water : Physiological limitations and technical possibilities

   Author : Mårten Silvanius; Oskar Frånberg; Rachel Lance; Blekinge Tekniska Högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Diving; diving apparatus; unmanned testing; hyperbaric; scuba; oxygen sensor; composite gas cylinder; carbon dioxide monitoring; decompression; hyperbaric oxygen therapy; Systemteknik; Systems Engineering;

   Abstract : The survival of humans in underwater environments necessitates a comprehensive understanding of both physiological factors and advanced technologies. Diving with self-contained underwater breathing apparatuses (SCUBA) remains one of the most common ways for human underwater activities. READ MORE

5. 3. Determinants of outcome in lumbar spinal stenosis surgery

   Author : Freyr Gauti Sigmundsson; Lund Ortopedi; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Lumbar spinal stenosis; outcome; pain; function; health related quality of life; decompression; spinal fusion;

   Abstract : Lumbar spinal stenosis (LSS) is a degenerative disorder of the spine that predominantly affects the elderly. LSS is the most common spinal disorder leading to surgery in Sweden. Recent randomized controlled studies have showed better outcome with surgery compared to conservative treatment. READ MORE

6. 4. On the Diagnosis and Treatment of Lumbar Spinal Stenosis

   Author : Konstantinos Pazarlis; Peter Försth; Bengt Sandén; Nikos Schizas; Karl Michaëlsson; Christian Hellum; Uppsala universitet; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; lumbar spinal stenosis; spine surgery; decompression; fusion; sagittal balance; electrodiagnosis; neurophysiology; Orthopaedics; Ortopedi; Neurology; Neurologi; Radiology; Radiologi;

   Abstract : Lumbar spinal stenosis (LSS) is the most common indication for spinal surgery. The aging global population is increasing the demand for strategies that promote physical activity among the elderly. As the prevalence of LSS rises, the condition gains constantly demographic and socioeconomic attention. READ MORE

7. 5. Decompression strain during long-duration, high-altitude exposures : Effects of intermittent excursions to moderate altitude and inspired fractions of oxygen

   Author : Rickard Ånell; Ola Eiken; Mikael Gennser; Mikael Grönkvist; Ole Hyldegaard; KTH; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Teknik och hälsa; Technology and Health;

   Abstract : Today´s tactical demands and new technical solutions in fighter aircraft entail longer exposure periods at higher altitudes than before. A low cabin pressure protects pilots from pulmonary barotrauma in case of a sudden loss of cabin pressure, however it can also generate a supersaturation of nitrogen (N2) in the tissues, increasing the risks of bubble formation and decompression sickness (DCS).
