Armillaria mellea na maslini i nove perspektive u zaštiti od truleži korijena

Gljiva Armillari amellea uzročnik je truleži korijena mnogih voćnih vrsta i vinove loze. Tijekom posljednjih nekoliko godina zabilježena je češća pojava gljive A. mellea na maslini u Hrvatskoj. Bolest uzrokuje odumiranje stabala i u pojedinim slučajevima može se smatrati ekonomski značajnom. U članku su ukratko opisani simptomi bolesti te mogućnosti zaštite masline od A. mellea otkopavanjem korijena i primjenom bioloških sredstava na osnovi Trichoderma vrsta.Basidiomycete fungus Armillaria mellea is the causal agent of root rot on many fruit species and on grapevine. Several outbreaks of A. mella on olive have been recorded in Croatia during the last few years. A. mellea causes decline and mortality of olive trees and can be regarded as economically important in particular cases.Armillaria root rot symptoms on olive and the possibility of disease management with root collar excavation or with Trichoderma‐based biological products are briefly described in the article

A prospective analysis of micronutrient status in quiescent inflammatory bowel disease

Background and aims: ESPEN guidelines advocate patients with inflammatory bowel disease (IBD) have their micronutrient levels checked regularly. This study described the micronutrient status of patients with quiescent IBD and explore whether biochemical micronutrient deficiencies related to time to subsequent disease relapse. Methods: Sixteen micronutrients were measured prospectively in blood of patients with IBD in clinical remission [Harvey Bradshaw Index (HBI) ≤4 in Crohn's disease (CD) and a partial Mayo score <2 in ulcerative colitis (UC)]. Patients were followed prospectively using the electronic patient records. The ability of micronutrient status to predict time to relapse was tested with survival analysis and Cox regression. Results: Ninety-three patients were enrolled; Fifty (54%) were also in biochemical remission defined as a normal faecal calprotectin (<250 μg/g), C-reactive protein (<10 mg/L) and serum albumin (>35 g/L). Deficiencies in vitamin D were identified in 27 (29%), zinc in 15 (16%), vitamin B6 in 13 (14%), vitamin C in 12 (13%) and vitamin B12 in 10 (11%). Fewer participants had low serum folate 7 (8%), ferritin 8 (9%), copper 4 (4%), magnesium 4 (4%) and plasma selenium 3 (3%). Zinc deficiency was predictive of a shorter time to subsequent relapse (HR: 6.9; 95%CI [1.9 to 26], p = 0.008); in sub analysis of those with CD this effect was even more profound (p = 0.001). Conclusion: We identified biochemical deficiencies for several micronutrients among adults with IBD clinically in remission. We have also highlighted a significant association between zinc deficiency and time to subsequent disease relapse in patients with CD which needs further investigation

A prospective evaluation of thiamine and magnesium status in relation to clinicopathological characteristics and 1-year mortality in patients with Alcohol Withdrawal Syndrome

Background: Alcohol withdrawal syndrome (AWS) is routinely treated with B-vitamins. However, the relationship between thiamine status and outcome is rarely examined. The aim of the present study was to examine the relationship between thiamine and magnesium status in patients with AWS. Methods: Patients (n = 127) presenting to the Emergency Department with AWS were recruited to a prospective observational study. Blood samples were drawn to measure whole blood thiamine diphosphate (TDP) and serum magnesium concentrations. Routine biochemistry and haematology assays were also conducted. The Glasgow Modified Alcohol Withdrawal Score (GMAWS) measured severity of AWS. Seizure history and current medications were also recorded. Results: The majority of patients (99%) had whole blood TDP concentration within/above the reference interval (275–675 ng/gHb) and had been prescribed thiamine (70%). In contrast, the majority of patients (60%) had low serum magnesium concentrations (< 0.75 mmol/L) and had not been prescribed magnesium (93%). The majority of patients (66%) had plasma lactate concentrations above 2.0 mmol/L. At 1 year, 13 patients with AWS had died giving a mortality rate of 11%. Male gender (p < 0.05), BMI < 20 kg/m2 (p < 0.01), GMAWS max ≥ 4 (p < 0.05), elevated plasma lactate (p < 0.01), low albumin (p < 0.05) and elevated serum CRP (p < 0.05) were associated with greater 1-year mortality. Also, low serum magnesium at time of recruitment to study and low serum magnesium at next admission were associated with higher 1-year mortality rates, (84% and 100% respectively; both p < 0.05). Conclusion: The prevalence of low circulating thiamine concentrations were rare and it was regularly prescribed in patients with AWS. In contrast, low serum magnesium concentrations were common and not prescribed. Low serum magnesium was associated more severe AWS and increased 1-year mortality
