- OBJECTIVE: To develop, evaluate, and apply a questionnaire-based instrument for investigation of specific symptoms in idiopathic environmental intolerance (IEI), called the Idiopathic Environmental Intolerance Symptom Inventory (IEISI). METHODS: Participants with IEI to chemicals responded to 82 candidate symptoms and to three subscales of the Quick Environmental Exposure and Sensitivity Inventory (QEESI) at a test (n = 207) and retest (n = 193) occasion. RESULTS: The 27 most commonly reported symptoms were selected and grouped into five symptom categories. Internal consistency, test-retest reliability, and concurrent validity were found to be satisfying. Cluster analysis identified two subgroups of IEI to chemicals. CONCLUSIONS: The results provide support for the IEISI being a reliable, valid, and fast tool for the study of specific symptom prevalence in IEI and encourage further study of subgroups.

- In this study we aimed to estimate the effect of diabetes, educational level and income on the risk of mortality and cardiovascular events in primary care patients with hypertension.We followed 62,557 individuals with hypertension diagnosed 2001-2008, in the Swedish Primary Care Cardiovascular Database. Study outcomes were death, myocardial infarction, and ischemic stroke, assessed using national registers until 2012. Cox regression models were used to estimate adjusted hazard ratios of outcomes according to diabetes status, educational level, and income.During follow-up, 13,231 individuals died, 9981 were diagnosed with diabetes, 4431 with myocardial infarction, and 4433 with ischemic stroke. Hazard ratios (95% confidence intervals) for diabetes versus no diabetes: mortality 1.57 (1.50-1.65), myocardial infarction 1.24 (1.14-1.34), and ischemic stroke 1.17 (1.07-1.27). Hazard ratios for diabetes and ≤9 years of school versus no diabetes and >12 years of school: mortality 1.56 (1.41-1.73), myocardial infarction 1.36 (1.17-1.59), and ischemic stroke 1.27 (1.08-1.50). Hazard ratios for diabetes and income in the lowest fifth group versus no diabetes and income in the highest fifth group: mortality 3.82 (3.36-4.34), myocardial infarction 2.00 (1.66-2.42), and ischemic stroke 1.91 (1.58-2.31).Diabetes combined with low income was associated with substantial excess risk of mortality, myocardial infarction and ischemic stroke among primary care patients with hypertension.

- BACKGROUND: The safety of pancreatic resection for elderly patients is still controversial. We examined the postoperative morbidity and mortality in patients aged 75 years or more undergoing pancreatic resection.METHODS: Patients undergoing pancreatic resection were studied retrospectively and the outcomes were compared between patients aged <75 and ≥75 years.RESULTS: Of the 556 patients enrolled, 78 (14%) were ≥75 years old. Elderly patients had significantly more co-morbidities, especially cardiovascular pathology (P=0.005). Also, elderly patients had significantly lower body mass index prior to surgery (P=0.005). There were no significant differences in terms of surgical procedures and tumor types between age groups. The incidence of postoperative pancreatic fistula grade A was significantly lower in the elderly group (P=0.022), but no significant differences were noted in the overall morbidity or the incidence of postpancreatectomy hemorrhage, delayed gastric emptying, bile leakage, cardiac complications, pulmonary complications or septic complications. The 30-day mortality rate was similar between groups (0.8% vs. 1.3%; P=0.532).CONCLUSION: Pancreatic resection is a safe option for selected elderly patients. Our study confirms that age alone should not preclude potentially curative surgical therapy.

- Objective: Glycoproteomics is an emerging subfield of proteomics. Tumor-specific variations in protein glycosylation might be potential targets for the development of new cancer diagnostics. Here, we performed high-throughput screening and targeted verification of glycome alterations in serum samples from patients with pancreatic cancer and the precancerous lesion intraductal papillary mucinous neoplasm (IPMN). Material and methods: The glycosylation profile of 1000 proteins was mapped in a discovery cohort comprising serum samples from 16 individuals, including 8 patients with pancreatic cancer and 8 healthy controls. The top 10 glycoprotein biomarker candidates with the highest signal intensity difference in glycosylation levels were evaluated in a cohort consisting of 109 serum samples, including 49 patients with resectable pancreatic cancer, 13 patients with resectable noninvasive IPMN and 47 healthy controls, using a targeted assay. Results: Multivariable analysis defined sets of panels comprising CA19-9 and distinctively glycosylated proteins for discrimination between pancreatic cancer, IPMN and healthy controls. A panel including CA 19-9, IL.17E, B7.1 and DR6 gave an AUC of 0.988 at 100% sensitivity at 90% specificity for the discrimination of stage 1 pancreatic cancer and healthy controls. B7.1 was found to be a valuable biomarker for differentiating between IPMN and healthy controls, with better performance alone than CA 19-9. Conclusions: Measurement of protein glycosylation profiles in serum may aid in the early detection of pancreatic cancer and precursor lesions.

- Background: Branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) presents a clinical conundrum. Rigorous long-term surveillance or surgical resection is recommended. The economic consequences of the management have not been fully investigated. Methods: A Markov decision model compared 4 strategies for low-risk BD-IPMN: I = upfront total pancreatectomy, II = upfront partial pancreatectomy, III = initial surveillance, IV = watchful waiting. Surveillance was based on the Swedish Guidelines for Pancreatic Cancer. Probabilities and costs were obtained from the participating unit and from the scientific literature. The incremental cost-effectiveness ratios (ICERs) were calculated and sensitivity analyses were performed by varying relevant parameters. Survival was reported in quality-adjusted life-years (QALYs). Results: Strategy III was the most cost-effective strategy with an ICER of €31 682 compared to strategy IV. Strategy I was the most expensive but yielded the best QALY (9.32). Total number of years, annual risk of pancreatic cancer and annual risk of a low-risk BD-IPMN turning into a high-risk lesion had the greatest impact in the model. Conclusions: Initial surveillance seems to be the most cost-effective strategy in the management of low-risk asymptomatic BD-IPMN. However, the possibility of personalized approaches remains to be investigated.

- Background Overweight, defined by body mass index (BMI), is correlated to complications following pancreaticoduodenectomy (PD). The aim of this study was to evaluate the impact of body constitution, measured with different anthropometric measures, and diabetes on complications following PD. Materials and methods Patients who underwent PD between 2000 and 2015 at Skåne University Hospital were retrospectively included. Body mass index (BMI), body surface area (BSA) and body fat percentage (BF%) were calculated. Overweight and obesity were defined by BMI according to the WHO classification (overweight ≥25 and obesity ≥30). Values equal to or above the median value were considered as large by BSA (≥1.87) and overweight by BF% (≥29.6% (male) and ≥38.9% (female)). Main endpoints were events of postoperative pancreatic fistula (POPF), post pancreatectomy hemorrhage (PPH), delayed gastric emptying (DGE) and complications classified according to the Clavien-Dindo classification. Multivariable analysis was performed using logistic regression and a subgroup analysis on diabetic patients was performed. Results In total 328 patients were included. The incidence of POPF grades B and C was increased among overweight and large patients defined by BMI (OR 4.16; p = 0.001), BSA (OR 2.88; p = 0.018) and BF% (OR 3.94; p = 0.001). However, the risk was not increased among diabetic patients with BMI≥25 and BMI≥30. DGE and complications classified as Clavien grade ≥3 were more common in patients defined as overweight by both BMI (OR 1.72; p = 0.024 and OR 2.63; p = 0.003, respectively) and BF% (OR 2.13; p = 0.001 and OR 2.31; p = 0.009, respectively). PPH was not more frequent in overweight or large patients. Conclusion Body constitution has an impact on the risk of severe complications following PD. BMI, BSA and BF% can all be used to identify risk groups. The risk of developing POPF grades B and C was significantly increased in overweight and large patients, but not in patients with coexisting diabetes.

Tidskriftsartikel (refereegranskat)abstract
- Background: Olfactory dysfunction together with neurological and cognitive symptoms are common after COVID-19. We aimed to study whether performance on olfactory and neuropsychological tests following infection predict post-COVID condition (PCC), persisting symptoms, and reduced health-related quality of life.Methods: Both hospitalized (N = 10) and non-hospitalized individuals (N = 56) were enrolled in this prospective cohort study. Participants were evaluated 1–3 months after infection with an olfactory threshold test and neuropsychological tests, which was used as predictors of PCC. A questionnaire outlining persisting symptoms and the validated instrument EuroQol five-dimension five-level for health-related quality of life assessment were used as outcome data 1 year after infection (N = 59). Principal component analysis was used to identify relevant predictors for PCC at 1 year.Results: Objectively assessed olfactory dysfunction at 1–3 months post infection, but not subjective olfactory symptoms, predicted post-COVID condition with reduced health-related quality of life (PCC+) at 1 year. The PCC+ group scored more often below the cut off for mild cognitive impairment on the Montreal Cognitive Assessment (61.5% vs. 21.7%) and higher on the Multidimensional Fatigue Inventory-20, compared to the group without PCC+.Conclusion: Our results indicate that objectively assessed, olfactory dysfunction is a predictor for PCC+. These findings underscore the importance of objective olfactory testing. We propose that olfactory screening in the early post-acute phase of COVID-19 infection might identify individuals that are at higher risk of developing long-term health sequalae.

- Sometimes we seem to look at the very object we are searching for, without consciously seeing it. How do we select object relevant information before we become aware of the object? We addressed this question in two recognition experiments involving pictures of fragmented objects. In Experiment 1, participants preferred to look at the target object rather than a control region 25 fixations prior to explicit recognition. Furthermore, participants inspected the target as if they had identified it around 9 fixations prior to explicit recognition. In Experiment 2, we investigated the influence of semantic knowledge in guiding object inspection prior to explicit recognition. Consistently, more specific knowledge about target identity made participants scan the fragmented stimulus more efficiently. For instance, non-target regions were rejected faster when participants knew the target object's name. Both experiments showed that participants were looking at the objects as if they knew them before they became aware of their identity.

Can we rationally design molecularly imprinted polymers?
- 2001

Ingår i: Analytica Chimica Acta. ; 435:1, s. 9-18

Tidskriftsartikel (refereegranskat)abstract
- The nearly exponential growth in the molecular imprinting literature has to a large extent been fuelled by an increasing awareness of the potential of molecular imprinting based technologies. Despite the acceptance of the technique by cognate disciplines and the demonstration of its usefulness in a number of enabling technologies, relatively little is known about the molecular level events underlying the imprinting process and subsequent recognition events. What rules govern imprint formation? Can we use such rules to rationally design molecularly imprinted polymers?
