- Wind damage to forests can be divided into (1) the direct damage done to the forest and (2) indirect effects. Indirect effects may be of different kinds and may affect the environ- ment as well as society. For example, falling trees can lead to power and telecommunica- tion failures or blocking of roads. The salvage harvest of fallen trees is another example and one that involves extremely dangerous work. In this overview we provide examples of different entities, services, and activities that may be affected by wind damage to for- ests. We illustrate how valuation of the damage depends on the perspective applied and how the affected entities, services, and activities may represent different types of values. Finally we suggest means for how to actively manage the risk in an ethically sustaina- ble way. Many of our examples will be drawn from the experiences of the wind damage Gudrun in southern Sweden on 8–9 January 2005. The direct as well as indirect effects, which are described, are by no means unique to the Gudrun wind damage event and similar or even worse effects have been described after the wind damage events Martin and Lothar in 1999, and Klaus in 2009.

- Dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) may be viewed as different points on a continuum reflecting the regional burden and distribution of pathology. An important clinical consideration is overlapping Alzheimer's disease (AD) pathology, since it has been reported that associated AD pathology in DLB shortens survival and leads to a more rapid cognitive decline. We aimed to investigate cerebrospinal fluid (CSF) biomarkers and the associated cognitive profile in DLB and PDD.

- Objectives - To measure cerebrospinal fluid (CSF) activity of acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) in patients with Alzheimer's disease (AD) participating in randomized clinical trials from three European centers, before and after long-term treatment with different AChE inhibitors (AChEIs). Materials and methods - Of the 144 patients included in the study, 104 were treated with donepezil, 15 with galantamine, 16 with rivastigmine, and nine with placebo. CSF AChE and BChE activities were measured at baseline and after 1-year treatment. Results - Donepezil and galantamine groups showed a significant increase in CSF AChE activity at follow-up, while no changes for BChE activity were observed; in donepezil group, a positive correlation between plasma concentration and AChE activity was documented. Conversely, in rivastigmine group, a decrease in CSF activity of both enzymes was observed. CSF AChE and BChE activities were not correlated with the clinical outcome in any group considered. CSF biomarkers did not show any change after treatment. Conclusions - AChEIs differently influence the activity of target enzymes in CSF independent of their pharmacodynamic effects.

- OBJECTIVE: To investigate if patterns of CSF biomarkers (T-tau, P-tau, and Abeta42) can predict cognitive progression, outcome of cholinesterase inhibitor (ChEI) treatment, and mortality in Alzheimer disease (AD). METHODS: We included outpatients with AD (n = 151) from a prospective treatment study with ChEI. At baseline, patients underwent cognitive assessments and lumbar puncture. The patients were assessed longitudinally. The 5-year survival rate was evaluated. CSF-Abeta42, T-tau, and P-tau were analyzed at baseline. K-means cluster analysis including the 3 CSF biomarkers was carried out. RESULTS: Cluster 1 contained 87 patients with low levels of Abeta42 and relatively low levels of T-tau and P-tau. Cluster 2 contained 52 patients with low levels of Abeta42 and intermediate levels of T-tau and P-tau. Cluster 3 contained 12 patients with low levels of Abeta42 and very high levels of CSF T-tau and P-tau. There were no differences between the clusters regarding age, gender, years of education, baseline instrumental activities of daily living, or APOE genotype. Even though there was no difference between cluster 3 and the other clusters in disease duration or global rating, the patients in cluster 3 performed worse on cognitive tests already at baseline. Patients in cluster 3 exhibited a very poor outcome of ChEI treatment. Finally, cognition deteriorated faster over time and the mortality rate was substantially increased in cluster 3. CONCLUSION: A subgroup of patients with Alzheimer disease with extreme levels of CSF biomarkers exhibits worse clinical outcomes over time, including faster progression of cognitive deficits, no response to ChEI treatment, and a higher mortality.

- We estimated the effect of adapting forest management to reduce the risk of wind damage under climate change on life-style services and forest yield in a south-Swedish forest using an integrated modelling approach. The ECHAM5/CCLM models had been used to produce a reference climate and a climate change scenario for the A1B emission scenario. Using the FinnFor model we estimated the effect of the climate change scenario on the site index for three common commercial tree species for the period 2001-2100. The adjusted site index was applied in projections of the forest using the Forest Time Machine model. The WINDA-GALES model was used to calculate the probability of wind damage in simulated future states of the forest. Effects of increasing forest owner motivation to take measures to adapt to climate change were simulated by comparing the effects of introducing adaptive measures in years 2001 and 2051, respectively. These adaptive measures had been identified in consultation with stakeholders. In the simulations, adaptive regimes resulted in generally increased yield, increased hunting potential and a higher number of forest management operations to be carried out, although other aspects of recreation services were reduced. The net return remained unaffected by most of the adaptive forest management regimes. The simulations were made without accounting for effects of predicted wind damage on the states of the forest. Forest owners perceiving increased risk of wind damage but also risk to their life-style would have to balance adaptive measures between these risks. We conclude that adapting forest management to reduce the risk of wind damage may impact on life-style services. Hence, this may affect the process of adaptation to an increasing risk of wind damage in southern Sweden.

- Aims: The aim of this study was to determine the incidence of neonatal morbidity in extremely preterm infants and to identify associated risk factors. Methods: Population based study of infants born before 27 gestational weeks and admitted for neonatal intensive care in Sweden during 2004-2007. Results: Of 638 admitted infants, 141 died. Among these, life support was withdrawn in 55 infants because of anticipation of poor long-term outcome. Of 497 surviving infants, 10% developed severe intraventricular haemorrhage (IVH), 5.7% cystic periventricular leucomalacia (cPVL), 41% septicaemia and 5.8% necrotizing enterocolitis (NEC); 61% had patent ductus arteriosus (PDA) and 34% developed retinopathy of prematurity (ROP) stage >= 3. Eighty-five per cent needed mechanical ventilation and 25% developed severe bronchopulmonary dysplasia (BPD). Forty-seven per cent survived to one year of age without any severe IVH, cPVL, severe ROP, severe BPD or NEC. Tocolysis increased and prolonged mechanical ventilation decreased the chances of survival without these morbidities. Maternal smoking and higher gestational duration were associated with lower risk of severe ROP, whereas PDA and poor growth increased this risk. Conclusion: Half of the infants surviving extremely preterm birth suffered from severe neonatal morbidities. Studies on how to reduce these morbidities and on the long-term health of survivors are warranted.

Tidskriftsartikel (refereegranskat)abstract
- Abstract Serum gamma-glutamyltransferase (GGT) is recommended as a marker for alcohol use disorders by the Swedish National Guidelines for Addiction, although it has a low sensitivity and specificity. GGT is inexpensive and easily accessible but additional knowledge is required on how to use the marker in patients with various levels of alcohol intake. Levels of GGT were obtained from 37 male social drinkers (< 100 grams pure alcohol weekly) and 18 former alcohol-dependent males with long-term (6 +/- 5 years) abstinence. Reproducibility was calculated through repeated blood samplings. Mean serum activity of GGT, in former alcohol-dependent males, was 0.26 microkat/L with an intra-class correlation coefficient of 0.85. In social drinkers, these figures were 0.34 microkat/L and 0.92, respectively. In treatment of males, with the goal of abstinence, upper reference limit is suggested to be 0.40 microkat/L. Goals of non-harmful drinking (< 100 grams weekly) suggest higher limits (0.62 microkat/L). Thirty percent increase of GGT should be suggestive of relapse.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: Because the TAQ1 A1 allele may be associated with alcohol-related medical illnesses, and medical illnesses in alcohol-dependent individuals are associated with increased mortality, we test the hypothesis that the TAQ1 A1 allele of the DRD2 gene is associated with increased mortality in alcohol-dependent individuals. METHODS: Following an index treatment episode, a 10-year follow-up study in 366 alcohol-dependent individuals was performed. The TAQ1 A1/A2 DRD2 genotype and allele frequencies were compared between those deceased and those still living at the 10-year point. In addition, the genotype and allele frequencies of these alcohol-dependent individuals were compared to that in 578 control subjects. RESULTS: The prevalence of the A1 allele differed between the deceased and living patients and the controls: 47% of the deceased were A1+, compared to 37% of the living patients and 32% of the controls. The frequency of the TAQ1 A1/A2 genotype also differed between the groups. Thus, 43% had the A1/A2 genotype in comparison with 32% in the living patients and 29% in the controls. The TAQ 1 A1 allele frequency differed between the groups. The frequency of A1 allele was 25% in the deceased patients compared to 21% in the living patients and 17% in the controls. CONCLUSION: The TAQ I A1 allele of the DRD2 gene (or DRD2 gene region) was associated with increased mortality over a 10-year period in alcohol-dependent individuals.

Tidskriftsartikel (refereegranskat)abstract
- AIMS: In several studies, possible risk factors/predictors for severe alcohol withdrawal syndrome (AWS), i.e. delirium tremens (DT) and/or seizures, have been investigated. We have recently observed that low blood platelet count could be such a risk factor/predictor. We therefore investigated whether such an association could be found using a large number of alcohol-dependent individuals (n = 334). METHODS: This study is a retrospectively conducted cohort study based on data from female and male patients (>20 years of age), consecutively admitted to an alcohol treatment unit. The individuals had to fulfil the discharge diagnoses alcohol dependence and alcohol withdrawal syndrome according to DSM-IV. RESULTS: During the treatment period, 3% of the patients developed DT, 2% seizures and none had co-occurrence of both conditions. Among those with DT, a higher proportion had thrombocytopenia. Those with seizures had lower blood platelet count and a higher proportion of them had thrombocytopenia. The sensitivity and specificity of thrombocytopenia for the development of DT during the treatment period was 70% and 69%, respectively. The positive predictive value (PPV) was 6% and the negative predictive value (NPV) was 99%. For the development of seizures, the figure for sensitivity was 75% and for specificity 69%. The figures for PPV and NPV were similar as those for the development of DT. CONCLUSIONS: Thrombocytopenia is more frequent in patients who develop severe AWS (DT or seizures). The findings, including the high NPV of thrombocytopenia, must be interpreted with caution due to the small number of patients who developed AWS. Further studies replicating the present finding are therefore needed before the clinical usefulness can be considered.
