- The aim of this study was to investigate whole blood coagulation on low blood plasma protein adsorbing surfaces. For this purpose, the polycationic graft copolymer poly(L-lysine)-g-poly(ethylene glycol) (PLL-g-PEG), PLL-g-PEG grafted with a cell adhesive peptide containing the amino acid sequence -Arg-Gly-Asp- (RGD), and PLL-g-PEG with a control peptide -Arg-Asp-Gly- (RDG) were adsorbed onto titanium (oxide), forming stable monomolecular adlayers through electrostatic attraction. Free oscillation rheometry and complementary techniques were used to measure the coagulation time (CT) and other interactions of the surfaces with native whole blood, recalcified platelet-rich plasma (PRP), and recalcified citrated platelet-free plasma (PFP). The results show that the uncoated titanium surfaces (reference) activated platelets and quickly triggered the coagulation cascade via the intrinsic pathway, whereas the PLL-g-PEG surfaces displayed a prolonged CT, approximately 2-3 times longer compared to uncoated titanium. We hypothesise that blood coagulates outside the vascular system independent of low protein adsorption to or activation by surfaces, due to the absence of an active down-regulation of procoagulative processes by the vascular endothelium.

- PURPOSE: The purpose of this study was to search for a deeper understanding of the ways patients with asthma/allergy experience their illness situation. METHOD: Thirty patients with a history of airway symptoms on allergen exposure and a positive skin prick test were included in the study. They took part in open-ended interviews in their homes twice at an interval of eight years, according to the phenomenographic approach. RESULTS: Fourteen different categories of experience were identified: 'knowing for oneself, 'body related', 'environment related', 'psychosomatic', 'magic', 'fatalism', 'compliance with medication', 'alternative medicine', 'health care', 'provocation', 'avoidance', 'normalization', 'normification' and 'pursuing life'. The analysis also showed that these categories, to varying degrees, were an expression of a desire to retain an ordinary healthy identity and its value. The longitudinal results showed that with time the patients distanced themselves from the medical perspective and found their own ways of thinking and acting in relation to their ill health, which is seen as strengthening for the identity. CONCLUSIONS: The different, individual ways patients with asthma/allergy developed in relation to the illness situation have a preserving effect on the identity, which ought to be considered in patient education and rehabilitation.

- OBJECTIVES: To investigate the use of indwelling catheters as injection aids at diabetes onset to reduce injection pain and pre-injection anxiety. STUDY DESIGN: Forty-one patients aged 8.1 +/- 3.7 years (range, 1-15) participated in this open, controlled randomized study. A 10-cm VAS with faces was used for scoring. A local anesthetic cream was used before all insertions. The control group used insulin pens with standard needles. After one week, the indwelling catheter group could choose regular injections but were included in the "intention to treat" analysis. RESULTS: Injection pain and anxiety decreased from day 1 to 15 in both groups (average, 4.1 injections/day). Pain was significantly lower for indwelling catheter injections when scored by parents (median, 1.2 cm vs 2.7 cm; P =.002), children/teenagers (0.8 cm vs 1.5 cm; P =.006), and nurses (1.4 cm vs 3.0 cm; P =.002). Parental pre-injection anxiety was also lower (1.2 cm vs 2.9 cm; P =.016). Taking injections, including inserting catheters, was found to be less problematic with an indwelling catheter (1.6 cm vs 3.3 cm;P =.009). During the 6-month follow-up, injection pain and injection problems were significantly lower in the catheter group. Mean catheter indwelling time was 3.7 days. Median pain for catheter insertion was 2.1 cm and for glucose testing was 0.9 cm. Sixteen of 20 patients continued to use indwelling catheters after 2 weeks, and 9 of 20 after 6 months. CONCLUSIONS: We found an evident relief of pre-injection anxiety and injection pain when using indwelling catheters for introducing insulin injections at the onset of diabetes.

- BackgroundPortal vein occlusion (PVO) is an established method to increase the volume of the future liver remnant (FLR). The main reasons for not proceeding to radical hepatectomy are lack of volume increase and tumor progression due to a wait-time interval of up to 8weeks. The hypothesis was that the increase in FLR volume is not linear and is largest during the first weeks.MethodsPatients with colorectal liver metastases (CRLM) and standardized future liver remnant (sFLR) <30% treated with PVO were prospectively included. All patients had at least one CT evaluation before radical hepatectomy.ResultsForty-eight patients were included. During the first week after PVO, the kinetic growth rate (KGR) was 5.4 (4), compared to 1.5 (+/- 2) between the first and second CT (p<0.05). For patients reaching adequate FLR and therefore treated with radical hepatectomy, the KGR was 7 (+/- 4) the first week, compared to 4.3 (+/- 2) for patients who failed to reach a sufficient volume (p=0.4). During the interval between the first and second CT, the KGR was 2.2 (+/- 2), respectively (+/- 0.1) (p=0.017).Discussion p id=Par4 The increase in liver volume after PVO is largest during the first week. As KGR decreases over time, it is important to shorten the interval between PVO and the first volume evaluation; this may aid in decision-making and reduce unnecessary waiting time.

Tidskriftsartikel (refereegranskat)abstract
- Background: Liver metastases are the most common cause of death for patients with colorectal cancer and affect up to half of the patients. Liver resection is an established method that can potentially be curative. For patients with extrahepatic disease (EHD), the role of liver surgery is less established. Methods: This is a retrospective study based on data from the national quality registry SweLiv. Data were obtained between 2009 and 2015. SweLiv is a validated registry and has been in use since 2009, with coverage above 95%. Patients with liver metastases and EHD were analyzed and cross-checked against the national death cause registry for survival analysis. Results: During the study period, 2,174 patients underwent surgery for colorectal liver metastases (CRLM), and 277 patients with EHD were treated with resection or ablation. The estimated median survival time for the entire cohort from liver resection/ablation was 40 months (95% CI, 32-47). The survival time for patients treated with liver resection was 45 months compared to 26 months for patients treated with ablation (95% CI 38-53, 18-33, P=0.001). A subgroup analysis of resected patients revealed that the group with pulmonary metastases had a significantly longer estimated median survival (50 months; 95 % CI, 39-60) than the group with lymph node metastases (32 months; 95% CI, 7-58) or peritoneal carcinomatosis (28 months; 95% CI, 14-41) (P=0.022 and 0.012, respectively). Other negative prognostic factors were major liver resection and nonradical liver resection. Conclusions: For patients with liver metastases and limited EHD, liver resection results in prolonged survival compared to what can be expected from chemotherapy alone.

- The aim of this study was to report longitudinal speech results in consecutively selected children from each of the six cleft centres in Sweden and to compare the results between centres. The children were born with a non-syndromic unilateral cleft lip and palate, and results from the same cohort at 5 years of age have previously been reported. Background data on medical care in terms of surgery, speech therapy, and hearing between 5 and 10 years of age were collected. Speech recordings of 56 children at 7 years and 54 at 10 years of age were blindly and independently assessed by four speech-language pathologists experienced in cleft palate speech. This resulted in measures of percent consonant correct (PCC) and perceived velopharyngeal competence rated on a three-tier scale. No statistically significant differences were found between centres. PCC scores at 7 years of age ranged from 44-100% (median 97.5) and at 10 years of age from 86-100% (median 100). Competent or marginally incompetent velopharyngeal function was found in 95% of the 7-year-olds and 98% of the 10-year-olds. Speech results were slightly better than previous reports of speech in children born with a unilateral cleft lip and palate.

Life's Essential 8 is inversely associated with high-sensitivity C-reactive protein

Tidskriftsartikel (refereegranskat)abstract
- Life's Essential 8 (LE8) is a score that includes modifiable risk factors for cardiovascular disease. Four health behaviors (diet, physical activity, nicotine exposure and sleep health) and four health factors (non-HDL cholesterol, blood glucose, blood pressure and body mass index) are included. These modifiable risk factors promote inflammation, and inflammation is one of the biological mechanisms of cardiovascular disease development. Thus, we examined the relationship between cardiovascular health measured by LE8 and low-grade inflammation measured by high-sensitivity C-reactive protein (hs-CRP) in the cross-sectional population-based Swedish CArdioPulmonary bioImage Study (SCAPIS). The study consisted of 28,010 participants between 50 and 64 years (51.5% women, mean age 57.5 years). All individual LE8 components were assigned a score between 0 (unhealthy) and 100 (healthy) points, and a global score was calculated. The association between LE8 scores and high-risk hs-CRP (defined as > 3.0 mg/L) was analyzed using adjusted logistic regression with spline analyses. There was a strong, dose response and inverse association between LE8 scores and levels of hs-CRP. Thus, those with a low LE8 score (= 50.0 points) had 5.8 higher (95% confidence interval [CI] 5.2-6.4) odds ratio (OR) of having high hs-CRP as compared to those with a high LE8 score (= 80.0 points). In conclusion, our findings show strong inverse associations between LE8 scores and levels of hs-CRP.
