Social network analysis reveals the failure of between-farm movement restrictions to reduce Salmonella transmission.

An increasing number of countries are investigating options to stop the spread of the emerging zoonotic infection Salmonella (S.) Dublin, which mainly spreads among bovines and with cattle manure. Detailed surveillance and cattle movement data from an 11-year period in Denmark provided an opportunity to gain new knowledge for mitigation options through a combined social network and simulation modeling approach. The analysis revealed similar network trends for non-infected and infected cattle farms despite stringent cattle movement restrictions imposed on infected farms in the national control program. The strongest predictive factor for farms becoming infected was their cattle movement activities in the previous month, with twice the effect of local transmission. The simulation model indicated an endemic S. Dublin occurrence, with peaks in outbreak probabilities and sizes around observed cattle movement activities. Therefore, pre- and post-movement measures within a 1-mo time-window may help reduce S. Dublin spread.

Association of medication clusters and subsequent labor market marginalization in refugee and Swedish-born young adults with common mental disorders in Sweden.

Little is known about the association between common mental disorders (CMD) and labor market integration among refugee and Swedish-born young adults. Socially disadvantaged patients such as refugees are more likely to discontinue their medication use prematurely. This study aimed to identify clusters of individuals with similar psychotropic medication patterns; and examine the relationship between cluster membership with labor market marginalization (LMM) in refugee and Swedish-born young adults with CMD. The study uses a longitudinal matched cohort aged 18-24 years with CMD diagnoses from Swedish registers covering 2006-2016. Dispensed psychotropic medications (antidepressants, antipsychotics, anxiolytics, sedative-hypnotics, mood stabilizers) were collected one year before and after CMD diagnosis. Clusters of patients with similar time courses of prescribed dosages were algorithmically identified. The association of cluster membership with subsequent LMM, (long-term sickness absence, SA, disability pension, DP, or long-term unemployment, UE) was assessed using Cox regression. Among 12,472 young adults with CMD, there were 13.9% with SA, 11.9% with DP, and 13.0% with UE during a mean follow-up of 4.1 years (SD 2.3 years). Six clusters of individuals were identified. A cluster with a sustained increase in all medication types yielded the highest hazard ratio (HR [95% CI]) 1.69 [1.34, 2.13] for SA and 2.63 [2.05, 3.38] for DP. The highest HRs of UE give a cluster with a concentrated peak in antidepressants at CMD diagnosis (HR 1.61[1.18, 2.18]). Refugees and Swedish-born showed similar associations between clusters and LMM. To prevent LMM, targeted support and early assessment of CMD treatment are needed for individuals with a sustained increase in psychotropic medication after CMD diagnosis and for refugees in high-risk clusters for UE characterized by a rapid lowering of treatment dosages, which could be an indicator for premature medication discontinuation.

Use of statins offsets insulin-related cancer risk.

AIM: There is firm evidence of a relation between type 2 diabetes (T2DM) and increased risks of cancer at various sites, but it is still unclear how different antihyperglycaemic therapies modify site-specific cancer risks. The aim of this study was to provide a complete characterization of all possible associations between individual T2DM therapies, statin use and site-specific cancers in the Austrian population. METHODS: Medical claims data of 1 847 051 patients with hospital stays during 2006-2007 were used to estimate age- and sex-dependent co-occurrences of site-specific cancer diagnoses and treatment with specific glucose-lowering drugs and statins. RESULTS: Patients treated with insulin or insulin secretagogues showed up to ninefold increased risks for cancers of the colon [males only (m)], liver (m), pancreas, lung (m) and brain (m), as well as a strongly decreased risk for prostate cancer (m). In patients taking statins, the risks were generally decreased, with a greater risk reduction in patients not receiving antihyperglycaemic therapies. The strongest effects were observed for use of insulin and pancreatic cancer [m: OR 4.5, 95% CI: 3.1-6.6; females (f): OR 4.2, 95% CI: 2.5-7.1], sulfonylureas (m: OR 2.8, 95% CI: 1.7-4.6; f: OR 3.0, 95% CI: 2.1-4.2) or glitazones and skin cancer (f: OR 0.54, 95% CI: 0.36-0.80), as well as metformin and cancer of the prostate (m: OR 0.82, 95% CI: 0.75-0.91) and corpus uteri (f: OR 1.7, 95% CI: 1.4-2.0) and non-Hodgkin's lymphoma (f: OR 0.76, 95% CI: 0.64-0.91). CONCLUSIONS: The use of statins offsets insulin-related cancer risks in patients with diabetes independently of sex and age. Overall, our data support the hyperglycaemia-cancer hypothesis. A reduction in endogenous or exogenous hyperinsulinaemia may be beneficial for cancer prevention. Therefore, insulin-sparing and insulin-sensitizing drugs should be the preferred treatment choices.

Vitamin D supplementation in inflammatory bowel disease: the role of dosage and patient compliance.

OBJECTIVES: Vitamin D substitution is recommended in patients with inflammatory bowel disease. Specific guidelines are lacking. The aim of this study was to assess the effect of vitamin D supplementation with respect to dosage and patient compliance. METHODS: A prospective cohort study of 167 Crohn disease/ulcerative colitis outpatients. Patients were screened for serum vitamin D (25OHD2+3) at the end of summer and in late winter. Demographic data, history of vitamin D supplementation were recorded and matched with prescription records. RESULTS: A total of 57 subjects used vitamin D supplementation (mean dose 1104 IU/day). 25OHD2+3 levels were lower (p < 0.001) in winter both in substituted and unsubstituted group, without any differences between groups within the same season. 25OHD2+3 levels did not correlate with the substitution dose. 52.1 % of subjects were fully compliant with substitution. 25OHD2+3 and prevalence of vitamin D deficit in this group were comparable with unsubstituted subjects except a higher prevalence of vitamin D insufficiency (p < 0.02). CONCLUSION: Fixed dosage of 1100 IU/day of vitamin D was insufficient to correct the deficiency. Patient compliance with vitamin D supplementation was low, however this fact did not significantly contribute to the degree of vitamin D deficiency in this dosage (Tab. 3, Fig. 1, Ref. 21).

Assessing resilience of healthcare infrastructure exposed to COVID-19: emerging risks, resilience indicators, interdependencies and international standards.

In the moment of preparation of this paper, the world is still globally in grip of the Corona (COVID-19) crisis, and the need to understand the broader overall framework of the crisis increases. As in similar cases in the past, also with this one, the main interest is on the "first response". Fully appreciating the efforts of those risking their lives facing pandemics, this paper tries to identify the main elements of the larger, possibly global, framework, supported by international standards, needed to deal with new (emerging) risks resulting from threats like Corona and assess the resilience of systems affected. The paper proposes that future solutions should include a number of new elements, related to both risk and resilience. That should include broadening the scope of attention, currently focused onto preparation and response phases, to the phases of "understanding risks", including emerging risks, and transformation and adaptation. The paper suggests to use resilience indicators in this process. The proposed approach has been applied in different cases involving critical infrastructures in Europe (energy supply, water supply, transportation, etc., exposed to various threats), including the health system in Austria. The detailed, indicator-based, resilience analysis included mapping resilience, resilience stress-testing, visualization, etc., showing, already before the COVID-19, the resilience (stress-testing) limits of the infrastructures. A simpler (57 indicator based) analysis has, then been done for 11 countries (including Austria). The paper links these results with the options available in the area of policies, standards, guidelines and tools (such as the RiskRadar), with focus on interdependencies and global standards-especially the new ISO 31,050, linking emerging risks and resilience.

Biosimilar granulocyte colony-stimulating factor is effective in reducing the duration of neutropenia after autologous peripheral blood stem cell transplantation.

BACKGROUND: Autologous peripheral blood stem cell transplantation (APBSCT) is the standard of therapy for patients with multiple myeloma and refractory Hodgkin's and non-Hodgkin's lymphomas. Granulocyte colony-stimulating factor (G-CSF) is widely used to accelerate hematopoietic recovery after transplantation and to reduce the morbidity and mortality associated with prolonged neutropenia. Biosimilar G-CSF is approved for the same indications as the originator G-CSF. This is one of the first reported uses of a biosimilar G-CSF for neutrophil recovery after APBSCT. METHODS: A total of 23 consecutive patients with hematological malignancy (multiple myeloma, Hodgkin's and non-Hodgkin's lymphomas, and acute myelogenous leukemia) were recruited at the Department of Haematooncology and Bone Marrow Transplantation at the Medical University of Lublin. Patients (12 men and 11 women; median age, 47 ± 13 years) received biosimilar G-CSF (Zarzio, Sandoz Biopharmaceuticals) after myeloablative chemotherapy (primarily BiCnU, etoposide, cytarabine, and melphalan or melphalan 140/200 mg/m(2)) followed by PBSCT. The median number of transplanted CD34+ cells was 4.2 ± 0.8 × 10(6)/kg body wt. G-CSF therapy was started when absolute neutrophil count (ANC) was <0.5 × 10(9)/L and was continued until ANC reached >1.5 × 10(9)/L for 3 consecutive days. Hematopoietic recovery parameters were compared with those in the control group, which consisted of 23 consecutive patients transplanted in the period before the biosimilar G-CSF group and receiving originator G-CSF (Neupogen, Amgen). RESULTS: The mean duration of treatment with biosimilar and originator G-CSF was 14.4 ± 5.1 and 18.6 ± 11.5 days, respectively (P = .43). The adverse event profile was comparable between the biosimilar G-CSF and originator G-CSF groups, with similar occurrence of neutropenic fever (5 versus 6 patients) and bone pain (7 patients in each group). One patient in the biosimilar group had neutropenic enterocolitis and sepsis. There was no case of death in either group. Granulocyte recovery in the study group was as follows: mean days to ANC >0.5 × 10(9)/L was 13.0 ± 4.0 days; to ANC >1.5 × 10(9)/L, 13.6 ± 4.5 days; and to ANC >1.5 × 10(9)/L, 14.0 ± 4.7 days. Mean duration until platelet recovery >20 × 10(9)/L was 16.1 ± 4.4 days. There were no statistically significant differences between the biosimilar and originator G-CSF groups in hematopoietic recovery parameters. CONCLUSIONS: Biosimilar G-CSF is safe and effective in reducing the duration of neutropenia in patients undergoing myeloablative therapy followed by APBSCT and probably in cost savings in transplantation budgets.
