- In terms of lipid nanoparticle (LNP) engineering, the relationship between particle composition, delivery efficacy, and the composition of the biocoronas that form around LNPs, is poorly understood. To explore this we analyze naturally efficacious biocorona compositions using an unbiased screening workflow. First, LNPs are complexed with plasma samples, from individual lean or obese male rats, and then functionally evaluated in vitro. Then, a fast, automated, and miniaturized method retrieves the LNPs with intact biocoronas, and multiomics analysis of the LNP-corona complexes reveals the particle corona content arising from each individual plasma sample. We find that the most efficacious LNP-corona complexes were enriched with high-density lipoprotein (HDL) and, compared to the commonly used corona-biomarker Apolipoprotein E, corona HDL content was a superior predictor of in-vivo activity. Using technically challenging and clinically relevant lipid nanoparticles, these methods reveal a previously unreported role for HDL as a source of ApoE and, form a framework for improving LNP therapeutic efficacy by controlling corona composition. ApoE is known to be important for lipid nanoparticle function. Here, the authors shows that efficacious coronal ApoE originates from high-density lipoprotein (HDL) particles and, enhances hepatic delivery, making HDL a superior biomarker for lipid nanoparticle potency.

- In 2005 a large outbreak of verotoxin-producing Escherichia coli (VTEC) occurred in Sweden. Cases were interviewed and cohort and case-control studies were conducted. Microbiological investigations were performed using polymerase chain reaction (PCR) to detect the Shiga-like toxin (Stx) genes followed by cultivation and pulsed-field gel electrophoresis. A total of 135 cases were recorded, including 11 cases of hemolytic uremic syndrome. The epidemiological investigations implicated lettuce as the most likely source of the outbreak, with an OR of 13.0 (CI 2.94-57.5) in the case-control study. The lettuce was irrigated by water from a small stream, and water samples were positive for Stx 2 by PCR. The identical VTEC O157 Stx 2 positive strain was isolated from the cases and in cattle at a farm upstream from the irrigation point. An active surveillance and reporting system was crucial and cooperation between all involved parties was essential for quickly identifying the cause of this outbreak. Handling of fresh greens from farm to table must be improved to minimize the risk of contamination.

- To describe relatives' perceived participation in discharge planning for patients with stroke and identify correlates to perceived participation. Stroke affects both patients and their relatives and previous research shows that relatives were often dissatisfied with their perceived involvement in discharge planning and the information they get. Prospective cross-sectional study. The study comprised 152 consecutively enrolled relatives (mean age = 60.8 years) of acute stroke patients admitted to a stroke unit in southern Sweden during 2003-2005. Data were collected through interviews 2-3 weeks after discharge using 'Relative's Questionnaire about Participation in Discharge planning'. This instrument measures perceived participation in three subscales: R-Information-Illness, R-Information-Care/support, and R-Goals and Needs. The Overall Rating of Relative's Perceived Participation in Discharge Planning was measured by a visual analogue scale (VAS) (1-10 score). Among the relatives, 56-68% reported positively according to R-Information-Illness, but 46-53% perceived that they did not receive any information about care/medication/rehabilitation/support. About 80% perceived no participation at all in goals and needs. The mean value of the VAS was 3.89 (SD 3.40) score. Regression analyses revealed that longer stay at hospital, patients with higher education, and relatives of female patients and female relatives were associated with relatives' perceptions of higher participation in discharge planning. Relatives perceived that they needed more information and knowledge about stroke and care/medication/rehabilitation/support. They also needed to be more involved in goal-setting and in identifying patient needs. Professionals should take into consideration these associated variables to improve relatives' perceived participation. Clinicians should give more attention to the altered situation of stroke patients' relatives when planning for continuing care and when setting postdischarge goals for the patients. The professionals need to develop strategies to involve relatives in sharing information, goal-setting and needs assessment in discharge planning.

National Knowledge-Driven Management of Obstructive Sleep Apnea-The Swedish Approach

Tidskriftsartikel (refereegranskat)abstract
- Introduction: This paper describes the development of "Swedish Guidelines for OSA treatment" and the underlying managed care process. The Apnea Hypopnea Index (AHI) is traditionally used as a single parameter for obstructive sleep apnea (OSA) severity classification, although poorly associated with symptomatology and outcome. We instead implement a novel matrix for shared treatment decisions based on available evidence. Methods: A national expert group including medical and dental specialists, nurses, and patient representatives developed the knowledge-driven management model. A Delphi round was performed amongst experts from all Swedish regions (N = 24). Evidence reflecting treatment effects was extracted from systematic reviews, meta-analyses, and randomized clinical trials. Results: The treatment decision in the process includes a matrix with five categories from a "very weak"" to "very strong" indication to treat, and it includes factors with potential influence on outcome, including (A) OSA-related symptoms, (B) cardiometabolic comorbidities, (C) frequency of respiratory events, and (D) age. OSA-related symptoms indicate a strong incitement to treat, whereas the absence of symptoms, age above 65 years, and no or well-controlled comorbidities indicate a weak treatment indication, irrespective of AHI. Conclusions: The novel treatment matrix is based on the effects of treatments rather than the actual frequency of respiratory events during sleep. A nationwide implementation of this matrix is ongoing, and the outcome is monitored in a prospective evaluation by means of the Swedish Sleep Apnea Registry (SESAR).

Trichloroethylene exposure in vapour degreasing and the urinary excretion of N-acetyl-beta-D-glucosaminidase

- In order to elucidate the potential nephrotoxicity of low level occupational exposure to trichloroethylene (TRI), urine analysis of the tubular enzyme N-acetyl-beta-D-glucosaminidase (U-NAG) was included in a cross-sectional study of metal degreasers in central Sweden. Eighty-six percent of 8-h TRI in air measurements were well below 50 mg/m3. Normal levels of NAG were found in morning urine samples from 29 workers compared to a historical reference group. A weak positive correlation (r = 0.48; P < 0.01) was observed between U-NAG activity and the concentration of the TRI metabolite trichloroacetic acid in urine but not with other estimates of recent or long-term exposure. In conclusion, TRI does not seem to be nephrotoxic at low exposure levels.

- To validate various sampling strategies in assessment of trichloroethylene (TCE) exposure, urine and air samples were obtained from 29 metal workers involved in vapor degreasing. Urinary trichloroacetic acid and trichloroethanol were useful metabolites to estimate TCE exposure on a group basis, but the predictive value of a single urine sample was low when related to the air concentration. With intermittent TCE exposure, the best information is obtained by analyzing both metabolites.
