A History of Dystonia: Ancient to Modern

Before 1911, when Hermann Oppenheim introduced the term dystonia, this movement disorder lacked a unifying descriptor. While words like epilepsy, apoplexy, and palsy have had their meanings since antiquity, references to dystonia are much harder to identify in historical documents. Torticollis is an exception, although there is difficulty distinguishing dystonic torticollis from congenital muscular torticollis. There are, nevertheless, possible representations of dystonia in literature and visual art from the pre-modern world. Eighteenth century systematic nosologists such as Linnaeus, de Sauvages, and Cullen had attempted to classify some spasmodic conditions, including torticollis. But only after Charcot's contributions to clinical neuroscience were the various forms of generalized and focal dystonia clearly delineated. They were categorized as névroses: Charcot's term for conditions without an identifiable neuroanatomical cause. For a time thereafter, psychoanalytic models of dystonia based on Freud's ideas about unconscious conflicts transduced into physical symptoms were ascendant, although there was always a dissenting “organic” school. With the rise of subspecialization in movement disorders during the 1970s, the pendulum swung strongly back toward organic causation. David Marsden's clinical and electrophysiological research on the adult-onset focal dystonias was particularly important in establishing a physical basis for these disorders. We are still in a period of “living history” of dystonia, with much yet to be understood about pathophysiology. Rigidly dualistic models have crumbled in the face of evidence of electrophysiological and psychopathological overlap between organic and functional dystonia. More flexible biopsychosocial frameworks may address the demand for new diagnostic and therapeutic rationales

Impact of e-learning on learner participation, attainment, retention, and progression in further education : report of a scoping study

Recent and ongoing work has assessed progress in the provision of Information and Learning Technologies (ILT) to support e-learning in the UK further education (FE) sector. On the whole, this indicates that a strong infrastructure is in place with targets for student and staff access to Internet enabled computers being met in most colleges. Some investigations have been undertaken to review the extent of use of ILT for learning and teaching. These have, however, been at a relatively basic level, for example purely quantifying use of virtual learning environments (VLEs) for storing course documentation. The Scottish Centre for Research into Online Learning and Assessment (SCROLLA) and the SCRE Centre at the University of Glasgow undertook a scoping study of the impact of e-learning on participation, attainment, progression and retention in further education. This study was intended to inform the development of a research design for a later large study of impact

HIV futures NZ2: Mate araikore a muri ake nei (Tuarua)

The Living with HIV Program is a part of the Australian Research Centre in Sex, Health and Society (ARCSHS) at La Trobe University. The program conducts social research into the lived experience of HIV. The HIV Futures New Zealand 2 survey was completed by 261 HIV positive people. 75.7% were male (196), 23.9% were female (62), and one person was transgender. 60.7% were gay men, 22.7% heterosexual women, 10.1% heterosexual men, 6.1% bisexual men, and 0.4% lesbian women. The respondents’ ages ranged from 23 to 88 years with a mean of 45.6 years and a median of 44.0 years. The majority of participants were New Zealand born (69.4%) and 89.8% of the participants spoke English at home, with North African languages accounting for most of the remainder. Of the total sample, 255 indicated their ethnicity. One hundred and seventy two were European/Pakeha (65.9%), 49 were African (18.8%), 17 were Maori (6.5%), nine were Asian (3.4%) and five were Pacific Islanders (1.9%)

The impact of blood donation deferral strategies on the eligibility of men who have sex with men and other sexual risk behavior in Australia

Background In Australia, a man cannot donate blood if he has had sex with another man within the past 3 months. However, this policy has been criticized as being discriminatory as it does not consider lower risk subgroups, and led to calls for modifications to the policy that more accurately distinguish risk among gay, bisexual, and other men who have sex with men (GBM). Study Design and Methods We used data from a nationally representative survey to estimate the proportion of GBM aged 18–74 years old who would be eligible to donate under current criteria and other scenarios. Results Among the 5178 survey participants, 155 (3.0%) were classified as GBM based on survey responses, Among the GBM, 40.2% (95% CI 28.0%–53.7%) were eligible to donate based on current criteria, and 21.0% (95% CI 14.5%–29.5%) were ineligible due to the 3 months deferral alone. Eligibility among GBM, all men, and the population increased as criteria were removed. Under the new Australian plasma donation criteria, 73.6% (95% CI 64.4%–81.1%) of GBM, 68.4% (95% CI 65.5%–71.2%) of all men, and 60.8% (95% CI 58.8%–62.8%) of the full population were estimated to be eligible. Only 16.1% (95% CI 8.6%–28.1%) of GBM knew that the male-to-male sex deferral period is 3 months. Discussion Changing the deferral criteria and sexual risk evaluation would lead to a higher proportion of GBM being eligible to donate blood. Knowledge of the current GBM deferral period is very low. Improved education about the current criteria and any future changes are required to improve blood donation rates

Accelerated aging: A marker for social factors resulting in cardiovascular events?

Background: Medicine and public health are shifting away from a purely personal responsibility model of cardiovascular disease (CVD) prevention towards a societal view targeting social and environmental conditions and how these result in disease. Given the strong association between social conditions and CVD outcomes, we hypothesize that accelerated aging, measuring earlier health decline associated with chronological aging through a combination of biomarkers, may be a marker for the association between social conditions and CVD. Methods: We used data from the Coronary Artery Risk Development in Young Adults study (CARDIA). Accelerated aging was defined as the difference between biological and chronological age. Biological age was derived as a combination of 7 biomarkers (total cholesterol, HDL, glucose, BMI, CRP, FEV1/h(2), MAP), representing the physiological effect of wear and tear usually associated with chronological aging. We studied accelerated aging measured in 2005-06 as a mediator of the association between social factors measured in 2000-01 and 1) any incident CVD event; 2) stroke; and 3) all-cause mortality occurring from 2007 through 18. Results: Among 2978 middle-aged participants, mean (SD) accelerated aging was 3.6 (11.6) years, i.e., the CARDIA cohort appeared to be, on average, 3 years older than its chronological age. Accelerated aging partially mediated the association between social factors and CVD (N=219), stroke (N=36), and mortality (N=59). Accelerated aging mediated 41% of the total effects of racial discrimination on stroke after adjustment for covariates. Accelerated aging also mediated other relationships but to lesser degrees. Conclusion: We provide new evidence that accelerated aging based on easily measurable biomarkers may be a viable marker to partially explain how social factors can lead to cardiovascular outcomes and death

The contribution of diet and genotype to iron status in women:a classical twin study

This is the first published report examining the combined effect of diet and genotype on body iron content using a classical twin study design. The aim of this study was to determine the relative contribution of genetic and environmental factors in determining iron status. The population was comprised of 200 BMI- and age-matched pairs of MZ and DZ healthy twins, characterised for habitual diet and 15 iron-related candidate genetic markers. Variance components analysis demonstrated that the heritability of serum ferritin (SF) and soluble transferrin receptor was 44% and 54% respectively. Measured single nucleotide polymorphisms explained 5% and selected dietary factors 6% of the variance in iron status; there was a negative association between calcium intake and body iron (p = 0.02) and SF (p = 0.04)

A large population based study of the Mental Health and Wellbeing of Children and Young People in the North of England

BACKGROUND: There has been a recent reported rise in prevalence of mental health problems among children in the United Kingdom, alongside increased referrals into specialist services. There is a need for up-to-date information regarding changing trends of young people's mental health to allow for improved understanding and service planning. OBJECTIVES: This article aims to provide an overview of the current mental health and well-being of years 8, 9 and 11 secondary school-aged pupils from two large regions in the North of England. METHOD: This was a cohort cross-sectional study. Measures including the Strengths and Difficulties questionnaire, the EQ-5D-Y, social media use questions, and a mental health service use questionnaire were completed by participants. RESULTS: In total, 6328 questionnaires were returned from 21 secondary schools. One in 10 participating pupils scored 'very high' for total mental health difficulties. Significant differences on well-being scores were found between both gender and year groups. CONCLUSION: In recent years, the proportion of children facing mental health problems has increased. In particular, high levels of female pupils and year 11 pupils report facing difficulties. It is important to develop targeted, accessible interventions, and to continue to collect up-to-date measures for this population

Synthesis of Stereoenriched Piperidines via Chemo- Enzymatic Dearomatization of Activated Pyridines

The development of efficient and sustainable methods for the synthesis of nitrogen heterocycles is an important goal for the chemical industry. In particular, substituted chiral piperidines are prominent targets due to their prevalence in medicinally relevant compounds and their precursors. A potential biocatalytic approach to the synthesis of this privileged scaffold would be the asymmetric dearomatization of readily assembled activated pyridines. However, nature has yet to yield a suitable biocatalyst specifically for this reaction. Here, by combining chemical synthesis and biocatalysis, we present a general chemo-enzymatic approach for the asymmetric dearomatization of activated pyridines for the preparation of substituted piperidines with precise stereochemistry. The key step involves a stereoselective one-pot amine oxidase/ene imine reductase cascade to convert N-substituted tetrahydropyridines to stereo-defined 3- and 3,4-substituted piperidines. This chemo-enzymatic approach has proved useful for key transformations in the syntheses of the antipsychotic drugs Preclamol and OSU-6162, as well as for the preparation of two important intermediates in synthetic routes of the ovarian cancer monotherapeutic Niraparib

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial

Background Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
