Plug-ins for ISpec

ISpec is an interface specification approach where templates provide slots to write interface requirements. These requirements can be written in various "plugin" formalisms. The practical question how to implement this in a tool is answered for regular expressions as a plug-in language. The requirements expressed by the regular expressions are used to assess the correctness of requirements expressed in sequence diagrams. In fact, an editor is coupled to the tool in which a plug-in language can be defined and a slot in a template can be linked to a particular language. The theoretical question how to formalise plug-ins in a relation calculus framework is investigated

Global, regional, and national incidence, prevalence, and years lived with disability for 310 diseases and injuries, 1990�2015: a systematic analysis for the Global Burden of Disease Study 2015

Background Non-fatal outcomes of disease and injury increasingly detract from the ability of the world's population to live in full health, a trend largely attributable to an epidemiological transition in many countries from causes affecting children, to non-communicable diseases (NCDs) more common in adults. For the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015), we estimated the incidence, prevalence, and years lived with disability for diseases and injuries at the global, regional, and national scale over the period of 1990 to 2015. Methods We estimated incidence and prevalence by age, sex, cause, year, and geography with a wide range of updated and standardised analytical procedures. Improvements from GBD 2013 included the addition of new data sources, updates to literature reviews for 85 causes, and the identification and inclusion of additional studies published up to November, 2015, to expand the database used for estimation of non-fatal outcomes to 60�900 unique data sources. Prevalence and incidence by cause and sequelae were determined with DisMod-MR 2.1, an improved version of the DisMod-MR Bayesian meta-regression tool first developed for GBD 2010 and GBD 2013. For some causes, we used alternative modelling strategies where the complexity of the disease was not suited to DisMod-MR 2.1 or where incidence and prevalence needed to be determined from other data. For GBD 2015 we created a summary indicator that combines measures of income per capita, educational attainment, and fertility (the Socio-demographic Index SDI) and used it to compare observed patterns of health loss to the expected pattern for countries or locations with similar SDI scores. Findings We generated 9·3 billion estimates from the various combinations of prevalence, incidence, and YLDs for causes, sequelae, and impairments by age, sex, geography, and year. In 2015, two causes had acute incidences in excess of 1 billion: upper respiratory infections (17·2 billion, 95% uncertainty interval UI 15·4�19·2 billion) and diarrhoeal diseases (2·39 billion, 2·30�2·50 billion). Eight causes of chronic disease and injury each affected more than 10% of the world's population in 2015: permanent caries, tension-type headache, iron-deficiency anaemia, age-related and other hearing loss, migraine, genital herpes, refraction and accommodation disorders, and ascariasis. The impairment that affected the greatest number of people in 2015 was anaemia, with 2·36 billion (2·35�2·37 billion) individuals affected. The second and third leading impairments by number of individuals affected were hearing loss and vision loss, respectively. Between 2005 and 2015, there was little change in the leading causes of years lived with disability (YLDs) on a global basis. NCDs accounted for 18 of the leading 20 causes of age-standardised YLDs on a global scale. Where rates were decreasing, the rate of decrease for YLDs was slower than that of years of life lost (YLLs) for nearly every cause included in our analysis. For low SDI geographies, Group 1 causes typically accounted for 20�30% of total disability, largely attributable to nutritional deficiencies, malaria, neglected tropical diseases, HIV/AIDS, and tuberculosis. Lower back and neck pain was the leading global cause of disability in 2015 in most countries. The leading cause was sense organ disorders in 22 countries in Asia and Africa and one in central Latin America; diabetes in four countries in Oceania; HIV/AIDS in three southern sub-Saharan African countries; collective violence and legal intervention in two north African and Middle Eastern countries; iron-deficiency anaemia in Somalia and Venezuela; depression in Uganda; onchoceriasis in Liberia; and other neglected tropical diseases in the Democratic Republic of the Congo. Interpretation Ageing of the world's population is increasing the number of people living with sequelae of diseases and injuries. Shifts in the epidemiological profile driven by socioeconomic change also contribute to the continued increase in years lived with disability (YLDs) as well as the rate of increase in YLDs. Despite limitations imposed by gaps in data availability and the variable quality of the data available, the standardised and comprehensive approach of the GBD study provides opportunities to examine broad trends, compare those trends between countries or subnational geographies, benchmark against locations at similar stages of development, and gauge the strength or weakness of the estimates available.

Symptoms of apathy are associated with progression from mild cognitive impairment to Alzheimer's disease in non-depressed subjects

Background: Apathy is a common symptom in various neuropsychiatric diseases including mild cognitive impairment (MCI) and dementia. Apathy may be associated with an increased risk of cognitive decline. The objective of this study was to investigate if apathy predicts the progression from MCI to Alzheimer’s disease (AD). Methods: The Alzheimer’s Disease Neuroimaging Initiative is a prospective multicentre cohort study. At baseline, 397 patients with MCI without major depression were included. Clinical data and the Geriatric Depression Scale at baseline were used. Apathy was defined based on the 3 apathy items of the 15-item Geriatric Depression Scale. The main outcome measure was the association of apathy with progression from MCI to AD. Results: During an average follow-up of 2.7 years (SD 1.0), 166 (41.8%) patients progressed to AD. The presence of symptoms of apathy without symptoms of depressive affect increased the risk of progression from MCI to AD (hazard ratio = 1.85, 95% CI = 1.09-3.15). Apathy in the context of symptoms of depressive affect or symptoms of depressive affect alone, without apathy, did not increase the risk of progression to AD. Conclusions: Symptoms of apathy, but not symptoms of depressive affect, increase the risk of progression from MCI to AD. Apathy in the context of symptoms of depressive affect does not increase this risk. Symptoms of apathy and depression have differential effects on cognitive decline

High-dose GH treatment limited to the prepubertal period in young children with idiopathic short stature does not increase adult height

Objective: To assess the long-term effect of prepubertal high-dose GH treatment on growth in children with idiopathic short stature (ISS). Design and methods: Forty children with no signs of puberty, age at start 4-8 years (girls) or 4-10 years (boys), height SDS - 2.0 SDS, were randomly allocated to receive GH at a dose of 2 mg/m(2) per day (equivalent to 75 mu g/kg per day at start and 64 mu g/kg per day at stop) until the onset of puberty for at least 2 years (preceded by two 3-month periods of treatment with low or intermediate doses of GH separated by two washout periods of 3 months) or no treatment. In 28 cases, adult height (AH) was assessed at a mean (S.D.) age of 20.4 (2.3) years. Results: GH-treated children (mean treatment period on high-dose GH 2.3 years (range 1.2-5.0 years)) showed an increased mean height SDS at discontinuation of the treatment compared with the controls (-1.3 (0.8) SDS versus -2.6 (0.8) SDS respectively). However, bone maturation was significantly accelerated in the GH-treated group compared with the controls (1.6 (0.4) versus 1.0 (0.2) years per year, respectively), and pubertal onset tended to advance. After an untreated interval of 3-12 years, AH was -2.1 (0.7) and -1.9 (0.6) in the GH-treated and control groups respectively. Age was a positive predictor of adult height gain. Conclusion: High-dose GH treatment restricted to the prepubertal period in young ISS children augments height gain during treatment, but accelerates bone maturation, resulting in a similar adult height compared with the untreated controls.Epidemiology in Pediatrics and Child Healt

Lower dementia risk with different classes of antihypertensive medication in older patients

Item does not contain fulltextOBJECTIVE: Use of antihypertensive medication (AHM) is potentially associated with a reduced risk of dementia. Both calcium channel blockers (CCBs) and angiotensin receptor blockers (ARBs) are suggested to have a more pronounced protective effect. We aimed to study the association between different classes of AHM and dementia in older people. METHODS: A subgroup of community-dwelling older people using AHM included in the 'Prevention of Dementia by Intensive Vascular Care' randomized controlled trial was studied. Incident dementia rates in participants with different AHM classes (mono and combination therapy) were compared with dementia rates in participants with any other AHM. RESULTS: At baseline, 1951 participants (55.3%) used AHM [mean age, 74.4 year (SD 2.5); mean SBP, 156.4 mmHg (SD 21.5)]. In total, 986 participants (50.5%) used beta-blockers, 798 diuretics (40.9%), 623 angiotensin- converting enzyme inhibitors (31.9%), 522 CCBs (26.8%), and 402 ARBs (20.6%). After 6.7 years (interquartile range 6.0-7.3) of follow-up, 136 participants (7.0%) developed dementia. Both use of CCBs [hazard ratio 0.56, 95% confidence interval (95% CI) 0.36-0.87] and ARBs (hazard ratio 0.60, 95% CI 0.37-0.98) were independently associated with a decreased risk of dementia. The association of CCBs with dementia was most apparent in participants without a history of cardiovascular disease (hazard ratio 0.38, 95% CI 0.18-0.81) and with uncontrolled hypertension (hazard ratio 0.26, 95% CI 0.11-0.61). SBP was not significantly lower in participants using CCBs or ARBs. CONCLUSION: Both use of CCBs and ARBs are independently associated with a decreased risk of dementia in older people
