ABSTRACT: There are different treatment options for obstructive sleep apnea, which are selectively used based on severity of sleep apnea, physical structure of the upper airway, and other medical aspects including co-morbidities. Weight loss as well as avoidance of alcohol and other CNS depressants is generally recommended. Positional training, oral appliances and surgery of the upper airways are used in selected cases. CPAP is the most effective method for treating obstructive sleep apnea irrespective of disease severity. In patients with central sleep apnea or Cheyne-Stokes respiration (CSA/CSR) diagnosis and treatment of the underlying cause is mandatory. Adaptive servo-ventilation appears to be an effective treatment modality for patients with complex sleep apnea and with CSA/CSR that is resistant to CPAP.

ABSTRACT: Für die Behandlung der obstruktiven Schlafapnoe stehen mehrere Behandlungsoptionen zur Verfügung, deren Einsatz vom Schweregrad
der Schlafapnoe, den anatomischen Strukturen und physikalischen Eigenschaften der oberen Atemwege sowie anderen medizinischen
Aspekten wie der Symptomatik beziehungsweise den Komorbiditäten abhängt. Generell werden Gewichtsreduktion, (abendliche) Alkoholkarenz
und Vermeidung atemdepressiver Substanzen empfohlen. Positionstraining, progenierende Kieferschienen und Chirurgie der oberen
Atemwege stehen für ausgewählte Fälle zur Verfügung. CPAP ist die effektivste Methode zur Behandlung der obstruktiven Schlafapnoe
– unabhängig vom Schweregrad. Bei Patienten mit zentraler Schlafapnoe oder Cheyne-Stokes-Atmung steht die Diagnostik und Behandlung
der Grunderkrankung an erster Stelle. Die adaptive Servoventilation (ASV) ist nach aktuellem Kenntnisstand die effektivste
Behandlungsmodalität für Patienten mit diesen schlafbezogenen Atemstörungen.

ABSTRACT: Precise measurements of the deuteron vector analyzing power Ayd and the tensor analyzing power Ayy of the H(d,gamma)He-3 capture reaction have been performed at deuteron energies of 29MeV and 45MeV. The data have been compared to theoretical state-of-the-art calculations available today. Due to the large sensitivity of polarization observables and the precision of the data light could be shed on small effects present in the dynamics of the reaction.

ABSTRACT: The electron-target-asymmetries A_parallel and A_perpendicular with target spin parallel and perpendicular to the momentum transfer q were measured for both the two-- and three-body breakup of 3He in the 3He(e,e'p)-reaction. Polarized electrons were scattered off polarized 3He in the quasielastic regime in parallel kinematics with the scattered electron and the knocked-out proton detected using the Three-Spectrometer-Facility at MAMI. The results are compared to Faddeev calculations which take into account Final State Interactions as well as Meson Exchange Currents. The experiment confirms the prediction of a large effect of Final State Interactions in the asymmetry of the three-body breakup and of an almost negligible one for the two-body breakup.

ABSTRACT: In acute pancreatitis the evaluation of severity is as important as the diagnosis. If there is evidence for severe pancreatitis, an immediate intensive care of all organ systems is needed, to avoid complications. Besides clinical signs, serum CRP is the most valuable parameter to define severity. According to present knowledge, a CT-scan is only needed in sepsis or multiorgan failure. Non-invasive ventilation should be started early in case of hypoxia. Up to now, no general benefit was detected for antibiotic prophylaxis or enteral nutrition. No consensus exists whether and when endoscopic interventions are superior to surgery in the treatment of infected necrosis.

ABSTRACT: Bei der akuten Pankreatitis steht neben der Diagnosestellung die Einschtzung des Schweregrades ganz im Vordergrund. Bei Hinweisen auf eine schwere Pankreatitis ist eine sofortige intensive berwachung aller Organsysteme des Patienten entscheidend, um Komplikationen zu vermeiden. Die Bestimmung von CRP gibt neben den klinischen Parametern den wichtigsten Hinweis auf den Schweregrad. Nach der derzeitigen Studienlage muss diskutiert werden, ob die Computertomographie nur bei Sepsis oder Multiorganversagen eingesetzt werden soll. Eine nichtinvasive Beatmung sollte bei Hypoxmie frhzeitig erfolgen. Die Evidenz ist derzeit noch nicht ausreichend, um den prophylaktischen Einsatz von Antibiotika und den generellen Einsatz von enteraler Ernhrung zu empfehlen. Auch ist derzeit nicht geklrt, ob interventionelle Manahmen oder die Operation geeignete Methoden zur Behandlung von infizierten Nekrosen sind.In acute pancreatitis the evaluation of severity is as important as the diagnosis.

ABSTRACT: The electric form factor of the neutron was determined from measurements of the d-->(e-->,e'n)p reaction for quasielastic kinematics. Polarized electrons were scattered off a polarized deuterated ammonia (15ND3) target in which the deuteron polarization was perpendicular to the momentum transfer. The scattered electrons were detected in a magnetic spectrometer in coincidence with neutrons in a large solid angle detector. We find G(n)(E)=0.0526+/-0.0033(stat)+/-0.0026(sys) and 0.0454+/-0.0054+/-0.0037 at Q(2)=0.5 and 1.0 (GeV/c)(2), respectively.

ABSTRACT: Asymmetries in quasi-elastic pol 3He(pol e,e'p) have been measured at a
momentum transfer of 0.67 (GeV/c)^2 and are compared to a calculation which
takes into account relativistic kinematics in the final state and a
relativistic one-body current operator. With an exact solution of the Faddeev
equation for the 3He-ground state and an approximate treatment of final state
interactions in the continuum good agreement is found with the experimental
data.

ABSTRACT: Precise data on the neutron magnetic form factor G_{mn} have been obtained with measurements of the ratio of cross sections of D(e,e'n) and D(e,e'p) up to momentum transfers of Q^2 = 0.9 (GeV/c)^2. Data with typical uncertainties of 1.5% are presented. These data allow for the first time to extract a precise value of the magnetic radius of the neutron.
