    The purpose of this paper is the relatively limited one of reviewing the literature for models which develop specific relationships between climatic variables and crop yields. Following a review of recent weather-crop yield modeling efforts we evaluate these models and suggest some conceptual models and data base improvements if we are to adequately project the impacts on crop production of expected future climatic change. Our review and evaluation centers on weather-crop yield models applicable to the central grain belt of the U.S., mainly the Corn Belt and Great Plains production regions.Crop Production/Industries,

    The effect of mindfulness group therapy on a broad range of psychiatric symptoms : A randomised controlled trial in primary health care

    Background The need for psychotherapy in primary health care is on the increase but individual-based treatment is costly. The main aim of this randomised controlled trial (RCT) was to compare the effect of mindfulness-based group therapy (MGT) with treatment as usual (TAU), mainly individual-based cognitive behavioural therapy (CBT), on a broad range of psychiatric symptoms in primary care patients diagnosed with depressive, anxiety and/or stress and adjustment disorders. An additional aim was to compare the effect of MGT with TAU on mindful attention awareness. Methods This 8-week RCT took place in 2012 at 16 primary care centres in southern Sweden. The study population included both men and women, aged 20–64 years (n = 215). A broad range of psychiatric symptoms were evaluated at baseline and at the 8-week follow-up using the Symptom Checklist-90 (SCL-90). Mindful attention awareness was also evaluated using the Mindful Attention Awareness Scale (MAAS). Results In both groups, the scores decreased significantly for all subscales and indexes in SCL-90, while the MAAS scores increased significantly. There were no significant differences in the change in psychiatric symptoms between the two groups. The mindfulness group had a somewhat larger change in scores than the control group on the MAAS (P = 0.06, non-significant). Conclusions No significant differences between MGT and TAU, mainly individual-based CBT, were found in treatment effect. Both types of therapies could be used in primary care patients with depressive, anxiety and/or stress and adjustment disorders, where MGT has a potential to save limited resources.

    Abstract Background According to the literature the three stone diseases, sialolithiasis (SL), urolithiasis (UL) and cholelithiasis (CL) share comorbidities. We assess familial and spouse risks between these stone disease and compare them to familial risks for concordant (same) stone disease. Methods Study population including familiar relationships was obtained from the Swedish Multigeneration Register and stone disease patients were identified from nation-wide medical records. Standardized incidence ratios (SIRs) were calculated for 0–83 year old offspring when their first-degree relatives were diagnosed with stone disease and the rates were compared to individuals without a family history of stone disease. Numbers of offspring with SL were 7906, for UL they were 170,757 and for CL they were 204,369. Results SIRs for concordant familial risks were 2.06 for SL, 1.94 for UL and 1.82 for CL. SIRs for SL and UL were slightly higher for women than for men. Familial risks between stone diseases were modest. The highest risk of 1.17 was for UL when family members were diagnosed with CL, or vice versa. The SIR for UL was 1.15 when family members were diagnosed with SL. Familial risks among spouses were increased only for UL-CL pairs (1.10). Conclusions Familial risks for concordant SL were 2.06 and marginally lower for the other diseases. Familial risks between stone diseases were low but higher than risks between spouses. The data show that familial clustering is unique to each individual stone disease which would imply distinct disease mechanisms. The results cast doubt on the reported comorbidities between these diseases

    Building sustainable hospitals: A resource interaction perspective

    Get PDF
    In response to a growing influence of patients, higher specialisation, technological advancement and the need to provide care services more efficiently, the issue of sustainability in healthcare has gained prominence. The purpose of this paper is to investigate how the social and economic sustainability of healthcare are dependent on interconnecting resources across organisational borders and in different settings over time. Adopting a product development process perspective, the paper explores the gap between a planned healthcare facility and how it actually came to be used, through a longitudinal case study of the Skandion clinic, a small, highly specialised, hospital in Sweden. The findings suggests that integration of healthcare resources over time is central to achieve social and economic sustainability goals. The results hereby contend the prevailing view of hospitals as independent organisational units and highlights the need for more holistic analyses of sustainability in healthcare. Analyses which take into account the complex interdependencies stretching across networks of interconnected facilities and organisational units

    Are there differences in all-cause and coronary heart disease mortality between immigrants in Sweden and in their country of birth? A follow-up study of total populations

    BACKGROUND: Mortality from cardiovascular diseases is higher among immigrants than native Swedes. It is not clear whether the high mortality persists from the country of birth or is a result of migration. The purpose of the present study was to analyse whether all-cause and coronary heart disease mortality differ between immigrants in Sweden and in the country of birth. METHODS: Two cohorts including the total population from Swedish national registers and WHO were defined. All-cause and CHD mortality are presented as age-adjusted incidence rates and incidence density ratios (IDR) in eight immigrant groups in Sweden and in their country of birth. The data were analysed using Poisson regression. RESULTS: The all-cause mortality risk was lower among seven of eight male immigrant groups (IDR 0.39–0.97) and among six of eight female immigrant groups (IDR 0.42–0.81) than in their country of birth. The CHD mortality risk was significantly lower in male immigrants from Norway (IDR = 0.84), Finland (IDR = 0.91), Germany (IDR = 0.84) and Hungary (IDR = 0.59) and among female immigrants from Germany (IDR = 0.66) and Hungary (IDR = 0.54) than in their country of birth. In contrast, there was a significantly higher CHD mortality risk in male immigrants from Southern Europe (IDR = 1.23) than in their country of birth. CONCLUSION: The all-cause mortality risk was lower in the majority of immigrant groups in Sweden than in their country of birth. The differences in CHD mortality risks were more complex. For countries with high CHD mortality, such as Finland and Hungary, the risk was lower among immigrants in Sweden than in their country of birth. For low-risk countries in South Europe, the risk was higher in immigrants in Sweden than in South Europe

    Lem2p (LEM2) and Cmp7p (CHMP7) function in ESCRT-dependent nuclear envelope remodeling in fission yeast

    Get PDF
    ESCRT‐III proteins have been implicated in sealing the nuclear envelope in mammals, both during nuclear assembly and following mechanical disruption. This sealing process requires the ESCRT‐II/ESCRT‐ III hybrid protein CHMP7 and the AAA ATPase VPS4. It remains unclear, however, how CHMP7 is recruited to breaches of the nuclear envelope. The fission yeast S. pombe is an attractive genetic model system for investigating this role of the ESCRT pathway because, in fission yeast, the nuclear envelope develops fenestrations that must be closed twice per cell cycle: upon mitotic entry when duplicated spindle pole bodies (SPB) are incorporated into the nuclear envelope and after a successful cell cycle when the SPBs are ejected back to cytoplasm. Here we report that deletion of fission yeast vps4 leads to severe defects in nuclear morphology and integrity, which causes delayed segregation of duplicated SPBs, asymmetric nuclear bipartition in mitosis, and slow growth. Interestingly, these phenotypes are spontaneously suppressed by loss‐of‐function mutations that arise in cmp7 (pombe CHMP7) or lem2, a member of the LEM (Lap2‐Emerin‐Man1) family of inner nuclear membrane proteins—implying that all three function in the same pathway. Based on these observations, we hypothesize that Lem2p acts as a nuclear site‐specific adaptor to recruit Cmp7p to the nuclear envelope

    The role of public actors in construction logistics: effects on and of relational interfaces

    Get PDF
    Public actors are increasingly enforcing the use of specifically designed construction logistics setups (CLS) to cope with logistical challenges and minimising disturbances on third parties in large construction projects. The organising of these CLS is contingent on the interaction among several types of actors. The purpose of the paper is to advance the understanding of the design and use of CLS and the distribution of various outcomes of such arrangements on the actors involved. The paper analyses the role of public actors in the initiating of CLS and how this affects the relational interfaces in the CLS triad of developers, contractors and logistics service providers, and the outcomes of their interactions. First, the main reason for a public actor to initiate a CLS is not cost, productivity or innovativity gains, but to decrease disturbances on third parties. Second, developers and contractors are forced to use the CLS initiated by the public actor. This makes them take on a forced customer role, explaining why these actors are often resistant to adopt to a certain CLS. Third, ripple effects, such as unintended costs and productivity impacts, occur in the construction supply chain because of the use of CLS

    Risk of Diabetes Among Young Adults Born Preterm in Sweden

    OBJECTIVE-Previous studies have suggested that preterm birth is associated with diabetes later in life. These studies have shown inconsistent results for late preterm births and have had various limitations, including the inability to evaluate diabetic outpatients or to estimate risk across the full range of gestational ages. Our objective was to determine whether preterm birth is associated with diabetes medication prescription in a national cohort of young adults. RESEARCH DESIGN AND METHODS-This was a national cohort study of 630,090 infants born in Sweden from 1973 through 1979 (including 27,953 born preterm, gestational age < 37 weeks), followed for diabetes medication prescription in 2005-2009 (ages 25.5-37.0 years). Medication data were obtained from all outpatient and inpatient pharmacies throughout Sweden. RESULTS-Individuals born preterm, including those born late preterm (gestational age 35-36 weeks), had modestly increased odds ratios (ORs) for diabetes medication prescription relative to those born full term, after adjusting for fetal growth and other potential confounders. Insulin and/or oral diabetes medications were prescribed to 1.5% of individuals born preterm compared with 1.2% of those born full term (adjusted OR 1.13 [95% CI 1.02-1.26]). Insulin without oral diabetes medications was prescribed to 1.0% of individuals born preterm compared with 0.8% of those born full term (1.22 [1.08-1.39]). CONCLUSIONS-Preterm birth, including late preterm birth, is associated with a modestly increased risk of diabetes in young Swedish adults. These findings have important public health implications given the increasing number of preterm births and the large disease burden of diabetes, particularly when diagnosed in young adulthood

    Toward a sustainable biomedical research enterprise: Finding consensus and implementing recommendations

    Get PDF
    The US research enterprise is under significant strain due to stagnant funding, an expanding workforce, and complex regulations that increase costs and slow the pace of research. In response, a number of groups have analyzed the problems and offered recommendations for resolving these issues. However, many of these recommendations lacked follow-up implementation, allowing the damage of stagnant funding and outdated policies to persist. Here, we analyze nine reports published since the beginning of 2012 and consolidate over 250 suggestions into eight consensus recommendations made by the majority of the reports. We then propose how to implement these consensus recommendations, and we identify critical issues, such as improving workforce diversity and stakeholder interactions, on which the community has yet to achieve consensus
