-
Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- Background and purpose: There has recently been focus on the advantages of minimally invasive surgery (MIS) over conventional surgery and on local infiltration analgesia (LIA) during knee arthroplasty. This prospective randomized controlled trial investigated whether MIS would result in earlier home readiness and reduced postoperative pain compared to conventional unicompartmental knee arthroplasty (UKA) where both groups received LIA. Patients and methods: 40 patients scheduled for UKA were randomized to group MIS or group CON (conventional surgery). Both groups received LIA, with a mixture of ropivacaine, ketorolac, and epinephrine, intra- and postoperatively. The primary endpoint was home readiness (time to fulfillment of discharge criteria). The patients were followed for 6 months. Results: We found no statistically significant difference in home readiness between group MIS, median (range) 24 (21–71) h compared to group CON, 24 (21–46) h. No statistically significant differences between the groups were found in the secondary endpoints: pain intensity, morphine consumption, knee function, hospital stay, patient satisfaction, Oxford Knee Score and EQ-5D. The side effects between the groups were also similar, except a higher incidence of nausea on the second postoperative day in group MIS compared with group CON. Interpretation: Minimally invasive surgery did not improve outcome after unicompartmental knee arthroplasty compared to conventional surgery, when both groups received local infiltration analgesia. The surgical approach (MIS or conventional surgery) should be selected according to surgeon’s preferences and local hospital policies. ClinicalTrials.gov. (Identifier NCT00991445).

- This study investigated the feasibility of targeting the free, unbound forms of prostate-specific antigen (fPSA) for in vivo imaging of prostate adenocarcinomas (PCa), as PSA is produced and secreted at abundance during every clinical stage and grade of PCa, including castration-resistant disease. We injected 125I-labeled monoclonal antibody PSA30 (specific for an epitope uniquely accessible on fPSA alone) intravenously in male nude mice carrying subcutaneous xenografts of LNCaP tumors (n=36). Mice were sacrificed over a time course from 4 hours to 13 days after injecting 125I-labeled PSA30. Tissue uptake of 125I-PSA30 at 48 and 168 hours after intravenous injection was compared with two clinically used positron emission tomography radiopharmaceuticals, 18F-fluoro-deoxy-glucose (18F-FDG) or 18F-choline, in cryosections using Digital AutoRadiography (DAR) and also compared with immunohistochemical staining of PSA and histopathology. On DAR, the areas with high 125I-PSA30 uptake corresponded mainly to morphologically intact and PSA-producing LNCaP cells, but did not associate with the areas of high uptake of either 18F-FDG or 18F-choline. Biodistribution of 125I-PSA30 measured in dissected organs ex vivo during 4 to 312 hours after intravenous injection demonstrated maximum selective tumor uptake 24–48 hours after antibody injection. Our data showed selective uptake in vivo of a monoclonal antibody highly specific for fPSA in LNCaP cells. Hence, in vivo imaging of fPSA may be feasible with putative usefulness in disseminated PCa.

Forskningsöversikt (refereegranskat)abstract
- In 2014 the Public Health Agency of Sweden and the Swedish Reference Group for Antiviral Therapy (RAV) conducted a review and analysis of the state of knowledge on the duration of follow-up after exposure to human immunodeficiency virus (HIV). Up until then a follow-up of 12 weeks after exposure had been recommended, but improved tests and new information on early diagnosis motivated a re-evaluation of the national recommendations by experts representing infectious diseases and microbiology, county medical officers, the RAV, the Public Health Agency, and other national authorities. Based on the current state of knowledge the Public Health Agency of Sweden and the RAV recommend, starting in April 2015, a follow-up period of 6 weeks after possible HIV-1 exposure, if HIV testing is performed using laboratory-based combination tests detecting both HIV antibody and antigen. If point-of-care rapid HIV tests are used, a follow-up period of 8 weeks is recommended, because currently available rapid tests have insufficient sensitivity for detection of HIV-1 antigen. A follow-up period of 12 weeks is recommended after a possible exposure for HIV-2, since presently used assays do not include HIV-2 antigens and only limited information is available on the development of HIV antibodies during early HIV-2 infection. If pre- or post-exposure prophylaxis is administered, the follow-up period is recommended to begin after completion of prophylaxis. Even if infection cannot be reliably excluded before the end of the recommended follow-up period, HIV testing should be performed at first contact for persons who seek such testing.

- The Paleo- Eskimo Saqqaq and Independence I cultures, documented from archaeological remains in Northern Canada and Greenland, represent the earliest human expansion into the New World's northern extremes. However, their origin and genetic relationship to later cultures are unknown. We sequenced a mitochondrial genome from a Paleo- Eskimo human by using 3400- to 4500- year- old frozen hair excavated from an early Greenlandic Saqqaq settlement. The sample is distinct from modern Native Americans and Neo- Eskimos, falling within haplogroup D2a1, a group previously observed among modern Aleuts and Siberian Sireniki Yuit. This result suggests that the earliest migrants into the New World's northern extremes derived from populations in the Bering Sea area and were not directly related to Native Americans or the later Neo- Eskimos that replaced them.

- BackgroundSepsis is a life-threatening condition where the risk of death has been reported to be even higher than that associated with the major complications of atherosclerosis, i.e. myocardial infarction and stroke. In all three conditions, early treatment could limit organ dysfunction and thereby improve the prognosis.AimTo describe what has been published in the literature a/ with regard to the association between delay until start of treatment and outcome in sepsis with the emphasis on the pre-hospital phase and b/ to present published data and the opportunity to improve various links in the pre-hospital chain of care in sepsis.MethodsA literature search was performed on the PubMed, Embase (Ovid SP) and Cochrane Library databases.ResultsIn overall terms, we found a small number of articles (n=12 of 1,162 unique hits) which addressed the prehospital phase. For each hour of delay until the start of antibiotics, the prognosis appeared to become worse. However, there was no evidence that prehospital treatment improved the prognosis.Studies indicated that about half of the patients with severe sepsis used the emergency medical service (EMS) for transport to hospital. Patients who used the EMS experienced a shorter delay to treatment with antibiotics and the start of early goal-directed therapy (EGDT). Among EMS-transported patients, those in whom the EMS staff already suspected sepsis at the scene had a shorter delay to treatment with antibiotics and the start of EGDT.There are insufficient data on other links in the prehospital chain of care, i.e. patients, bystanders and dispatchers.ConclusionSevere sepsis is a life-threatening condition. Previous studies suggest that, with every hour of delay until the start of antibiotics, the prognosis deteriorates. About half of the patients use the EMS. We need to know more about the present situation with regard to the different links in the prehospital chain of care in sepsis.

- Objectives Coronary angiography is the golden standard when myocardial ischemia after CABG occurs. We summarize our experience of acute coronary angiography after CABG. Design All 4446 patients (mean age 68 ± 9 years, 22% women) who underwent CABG 2007 to 2012 were included in this retrospective observational study. Incidence, indications, findings, measures of acute angiography after CABG was assessed. Outcome variables were compared between patients who underwent angiography and those who did not. Results Eighty-seven patients (2%) underwent acute coronary angiography. Patients undergoing angiography had ECG changes (92%), echocardiographic alterations (48%), hemodynamic instability (28%), angina (15%), and/or arrhythmia (13%). Positive findings were detected in 69% of the cases. Only ECG changes as indication for angiography had a moderate association with positive findings, but the precision increased if other sign(s) of ischemia were present. Thirty-day mortality (7% versus 2%, p = 0.002) was higher and long-term-cumulative survival lower (77% versus 87% at five years, p = 0.043) in angiography patients. Conclusions Acute angiography is a rare event after CABG. Postoperative myocardial ischemia leading to acute coronary angiography is associated with increased short-term and long-term mortality.

- BACKGROUND: An alcohol-induced change in serum transferrin glycosylation, termed carbohydrate-deficient transferrin (CDT), is widely used as a biomarker of heavy long-term drinking. This study examined the transferrin glycosylation profile and the risk for false-positive CDT results during pregnancy. METHODS: Serum samples were collected from 24 healthy pregnant women starting in gestation week 9-21, throughout pregnancy, and 8 or more weeks after delivery. Altogether 171 sera (5-9 samples/person) were analysed. Transferrin glycoforms were quantified as a percentage of total transferrin, using an HPLC candidate reference method for CDT. RESULTS: During pregnancy, the relative disialo-, pentasialo- and hexasialotransferrin levels increased gradually, whereas trisialo- and tetrasialotransferrin were reduced. This effect was most pronounced in the third trimester. For disialotransferrin, the main target in CDT testing, initial values of 1.07±0.17% (mean±SD) increased to 1.61±0.23% before delivery (~50% increase). Nine (38%) pregnant women reached %disialotransferrin values ≥1.7% (97.5th percentile for controls) but all results were <2.0%. In the postpartum samples, all glycoform levels had returned towards the starting values. CONCLUSIONS: These results suggest that the cutoff for %disialotransferrin and %CDT employed to indicate heavy long-term drinking need to be raised slightly in pregnant women, to minimize the risk for false-positive results on CDT testing.
