Förstudie obemannade farkoster
- 2012
-
Rapport (populärvet., debatt m.m.)abstract
- Obemannade farkoster används allt oftare, och i allt fler roller, i dagens kon- flikter. Denna rapport ger en bred överblick över området militära obemannade farkoster, samt rekommendationer för inriktningen av framtida FoU-satsningar inom området.Överblicken över området har fokus på både system, förmågor och verksam- heter som är relevanta för Försvarsmakten. Genom att låta de insatsförmågor som definieras i FMUP (Försvarsmaktens utvecklingsplan) gå som en röd tråd genom rapporten, både när specifika system diskuteras och när möjliga scena- rier där obemannade farkoster kan vara till nytta beskrivs, har vi försökt hålla både bredd och relevans i dokumentet.Rekommendationerna vilar på en genomgång av de inriktningsdokument som producerats i Försvarsmakten, t.ex. Perspektivplanneringen och FMUP, besök vid de enheter som dagligen använder obemannade farkoster, UAV-enheten i Karlsborg och Swedec i Eksjö, samt den områdesöverblick som nämns ovan. Slutsatserna är att den effektivaste kompetensuppbyggnaden och kunskapsöver- föringen fås om man skapar breda tvärvetenskapliga projekt inom respektive systemkategori (UAV, UGV, etc) med nära kontakter till materielförsörjnings- processen och perspektivplaneringen. Dessa kan samla kompetensen inom FHS och FOI, övervaka forskningsfronten genom att bevaka tävlingar, konferenser samt delta i internationella samarbeten, samt överföra det samlade resultaten till Försvarsmakten genom demonstrationer av verkliga eller simulerade delsy- stem och interaktiva simuleringar av hela system. Just systemsimuleringar kan göras särskilt realistiska, eftersom interaktionen med de riktiga obemannade systemen till stor del sker igenom kontrollstationernas datorer. På så sätt ska- pas en känsla för både hot och möjligheter med de nya systemen, vilket gagnar både taktikutveckling och materielprocesser.

- Common colds often trigger asthma exacerbations. The present study compared cold-related severe exacerbations during budesonide/formoterol maintenance and reliever therapy, and different regimens of maintenance inhaled corticosteroids (ICS), with or without long-acting beta(2)-agonists (LABA), and with as-needed short-acting beta(2)-agonists (SABA) or LABA. Reported colds and severe exacerbations (defined by oral corticosteroid use and/or hospitalisation/emergency room visit) were assessed for 12,507 patients during 6-12 months of double-blind treatment. Exacerbations occurring <= 14 days after onset of reported colds were analysed by a Poisson model. The incidence of colds was similar across treatments. Asthma symptoms and reliever use increased during colds. Budesonide/formoterol maintenance and reliever therapy reduced severe cold-related exacerbations by 36% versus pooled comparators plus SABA (rate ratio (RR) 0.64; p=0.002), and for individual treatment comparisons, by 52% versus the same maintenance dose of ICS/LABA (RR 0.48; p < 0.001); there were nonsignificant reductions versus higher maintenance doses of ICS or ICS/LABA (RR 0.83 and 0.72, respectively). As-needed LABA did not reduce cold-related exacerbations versus as-needed SABA (RR 0.96). Severe cold-related exacerbations were reduced by budesonide/formoterol maintenance and reliever therapy compared with ICS with or without LABA and with as-needed SABA. Subanalyses suggested the importance of the ICS component in reducing cold-related exacerbations. Future studies should document the cause of exacerbations, in order to allow identification of different treatment effects.

Expertise-based randomized clinical trial of laparoscopic versus small-incision open cholecystectomy

- Background: Several randomized clinical trials have compared laparoscopic cholecystectomy (LC) and small-incision open cholecystectomy (SIOC). Most have had wide exclusion criteria and none was expertise-based. The aim of this expertise-based randomized trial was to compare healthcare costs, quality of life (QoL), pain and clinical outcomes after LC and SIOC. Methods: Patients scheduled for cholecystectomy were randomized to treatment by one of two teams of surgeons with a preference for either LC or SIOC. Each team performed their specific method (SIOC or LC) as a first-choice operation, but converted to open cholecystectomy and common bile duct exploration when necessary. Intraoperative cholangiography was carried out routinely. The intention was to include all patients undergoing cholecystectomy, including emergency operations and procedures involving surgical training for residents. Results: Some 74.9 per cent of all patients undergoing cholecystectomy were included. Of 355 patients randomized, 333 were analysed. Self-estimated QoL scores in 258 patients, analysed by the area under the curve method, were significantly lower in the SIOC group at 1 month after surgery: median 2326 (95 per cent confidence interval 2187 to 2391) compared with 2411 (2334 to 2502) for the LC group (P = 0.030). The mean(s.d.) duration of operation was shorter for SIOC: 97(41) versus 120(48) min (P < 0.001). There were no significant differences between the groups in conversion rate, pain, complications, length of hospital stay or readmissions. Conclusion: SIOC had comparable surgical results but slightly worse short-term QoL compared with LC. Registration number: NCT00370344 (http://www.clinicaltrials.gov).

Tidskriftsartikel (refereegranskat)abstract
- Recurrence of leukemia after the completion of induction and consolidation chemotherapy is a significant clinical concern in acute myeloid leukemia (AML). Apart from allogeneic bone marrow transplantation there is no consensus about effective relapse-protective therapy beyond the consolidation phase, and the standard of care for the majority of patients in complete remission (CR) hence is no treatment. Here we present updated results from a phase 3 trial (n=320) evaluating the prevention of relapse in AML patients receiving immunotherapy with histamine dihydrochloride (HDC) and low-dose interleukin-2 (IL-2). This trial was previously reported to meet the primary endpoint of improved leukemia-free survival (LFS) in the primary population of all randomized patients. Our results imply that treatment with HDC/IL-2 prevents relapse in patients 40–70 years old in first CR (p=0.008, leukemia-free survival (LFS), n=190, log rank test) with a more than 80% relative increase in the likelihood of LFS at 3 years. HDC/IL-2 was not significantly efficacious in young patients (<40 years old). Further studies are underway to define the impact of HDC/IL-2 on immune function and the putative efficacy of therapy in genetic subgroups of AML.
