Hired helpers at the nest: The association between life-cycle servants and net fertility in North Orkney, 1851-1911.

OBJECTIVES: The presence of kin is often, but not always, associated with higher fertility in historical populations. However, the effect of other household members on fertility is less frequently studied. While not genetically related, life-cycle servants lived and worked alongside household members and may have provided assistance to reproducing families. Female servants in particular may have helped mothers with small children through direct help with childcare activities or by replacing the economic effort of mothers whose work was not compatible with childcare. This study examines the presence of servants in the households of married women of reproductive age to assess whether households with young children are more likely to also have servants. MATERIALS AND METHODS: This study uses individual-level census data from North Orkney, Scotland (1851-1911) to investigate the relationship between the presence of servants in households and a measure of recent net marital fertility, the number of women's own-children under age 5, using logistic regression models. RESULTS: Households with young children were more likely to have a female, but not male, servant in the household after controlling for the effects of other possible helpers, including older children, mothers, and mothers-in-law. DISCUSSION: These findings are consistent with prior research that indicates the importance of female labor to smallholder agricultural households and suggests that female servants may have provided support to reproducing families. Life-cycle servants should be considered one component of biocultural reproduction in historical Northwest Europe. The use of hired help is not restricted to contemporary or elite groups.

No clear evidence for correlations between handgrip strength and sexually dimorphic acoustic properties of voices.

OBJECTIVES: Recent research on the signal value of masculine physical characteristics in men has focused on the possibility that such characteristics are valid cues of physical strength. However, evidence that sexually dimorphic vocal characteristics are correlated with physical strength is equivocal. Consequently, we undertook a further test for possible relationships between physical strength and masculine vocal characteristics. METHODS: We tested the putative relationships between White UK (N = 115) and Chinese (N = 106) participants' handgrip strength (a widely used proxy for general upper-body strength) and five sexually dimorphic acoustic properties of voices: fundamental frequency (F0), fundamental frequency's SD (F0-SD), formant dispersion (Df), formant position (Pf), and estimated vocal-tract length (VTL). RESULTS: Analyses revealed no clear evidence that stronger individuals had more masculine voices. CONCLUSIONS: Our results do not support the hypothesis that masculine vocal characteristics are a valid cue of physical strength.

The first description of the complete natural history of uveal melanoma by two Scottish surgeons, Allan Burns and James Wardrop.

James Wardrop (1782-1869), a young Scottish surgeon and an early ophthalmologist in Edinburgh, is credited for describing in 1809 retinoblastoma as an entity in his treatise 'Observations on Fungus Haematodes or Soft Cancer'. His treatise also reveals that Allan Burns (1781-1813), another young Scottish surgeon and anatomist, had invited Wardrop to assist in enucleating an eye from a 41-year-old Glasgow woman who, in retrospect, had a uveal melanoma. Her eye had become blind 4 months after symptoms of exudative retinal detachment had appeared, and it had become painful after a further 2-4 months. The tumour eventually perforated the sclera, and she died within a year thereafter of hepatic metastases. Burns and Wardrop went on to publish detailed parallel accounts of the symptoms, signs, ophthalmic pathology and post-mortem findings regarding the primary, recurrent and metastatic tumour. Burns may have performed the post-mortem after exhuming the body, a common occurrence in early 19th Century Scotland, a thriving hub for teaching morbid anatomy to young surgeons at the time.

Clinical Features, Molecular Heterogeneity, and Prognostic Implications in YARS2-Related Mitochondrial Myopathy.

Importance: YARS2 mutations have been associated with a clinical triad of myopathy, lactic acidosis, and sideroblastic anemia in predominantly Middle Eastern populations. However, the identification of new patients expands the clinical and molecular spectrum of mitochondrial disorders. Objectives: To review the clinical, molecular, and genetic features of YARS2-related mitochondrial disease and to demonstrate a new Scottish founder variant. Design, Setting, and Participants: An observational case series study was conducted at a national diagnostic center for mitochondrial disease in Newcastle upon Tyne, England, and review of cases published in the literature. Six adults in a well-defined mitochondrial disease cohort and 11 additional cases described in the literature were identified with YARS2 variants between January 1, 2000, and January 31, 2015. Main Outcome and Measures: The spectrum of clinical features and disease progression in unreported and reported patients with pathogenic YARS2 variants. Results: Seventeen patients (median [interquartile range] age at onset, 1.5 [9.8] years) with YARS2-related mitochondrial myopathy were identified. Fifteen individuals (88%) exhibited an elevated blood lactate level accompanied by generalized myopathy; only 12 patients (71%) manifested with sideroblastic anemia. Hypertrophic cardiomyopathy (9 [53%]) and respiratory insufficiency (8 [47%]) were also prominent clinical features. Central nervous system involvement was rare. Muscle studies showed global cytochrome-c oxidase deficiency in all patients tested and severe, combined respiratory chain complex activity deficiencies. Microsatellite genotyping demonstrated a common founder effect shared between 3 Scottish patients with a p.Leu392Ser variant. Immunoblotting from fibroblasts and myoblasts of an affected Scottish patient showed normal YARS2 protein levels and mild respiratory chain complex defects. Yeast modeling of novel missense YARS2 variants closely correlated with the severity of clinical phenotypes. Conclusions and Relevance: The p.Leu392Ser variant is likely a newly identified founder YARS2 mutation. Testing for pathogenic YARS2 variants should be considered in patients presenting with mitochondrial myopathy, characterized by exercise intolerance and muscle weakness even in the absence of sideroblastic anemia irrespective of ethnicity. Regular surveillance and early treatment for cardiomyopathy and respiratory muscle weakness is advocated because early treatment may mitigate the significant morbidity and mortality associated with this genetic disorder.

Does measurement technique explain the mismatch between European head size and WHO charts?

OBJECTIVE: To test whether different measuring techniques produce systematic differences in head size that could explain the large head circumferences found in Northern European children compared with the WHO standard. DESIGN: Cross-sectional observational study. SETTING: Scotland, UK. PATIENTS: Study 1: 68 healthy children aged 0.4-18 months from mother and baby groups and a medical students teaching session. Study 2: 81 children aged 0.4 to 25 months from hospital wards and neonatal follow-up clinics. INTERVENTIONS: Study 1: heads measured with plastic tape using both the WHO tight and UK loose technique. Study 2: heads measured using WHO research technique and a metal measuring tape and compared with routinely acquired measurements. MAIN OUTCOME MEASURES: Mean difference in head z-scores using WHO standard between the two methods. RESULTS: The tight technique resulted in a mean (95% CI) z-score difference of 0.41 (0.27 to 0.54, p<0.001) in study 1 and 0.44 (0.36 to 0.53, p<0.001) in study 2. However, the mean WHO measurements in the healthy infants still produced a mean z-score that was two-third of a centile space (0.54 SD (0.28 to 0.79) p<0.001) above the 50th centile. CONCLUSION: The WHO measurement techniques produced significantly lower measures of head size, but average healthy Scottish children still had larger heads than the WHO standard using this method.

Recent genomic heritage in Scotland.

BACKGROUND: The Generation Scotland Scottish Family Health Study (GS:SFHS) includes 23,960 participants from across Scotland with records for many health-related traits and environmental covariates. Genotypes at ~700 K SNPs are currently available for 10,000 participants. The cohort was designed as a resource for genetic and health related research and the study of complex traits. In this study we developed a suite of analyses to disentangle the genomic differentiation within GS:SFHS individuals to describe and optimise the sample and methods for future analyses. RESULTS: We combined the genotypic information of GS:SFHS with 1092 individuals from the 1000 Genomes project and estimated their genomic relationships. Then, we performed Principal Component Analyses of the resulting relationships to investigate the genomic origin of different groups. We characterised two groups of individuals: those with a few sparse rare markers in the genome, and those with several large rare haplotypes which might represent relatively recent exogenous ancestors. We identified some individuals with likely Italian ancestry and a group with some potential African/Asian ancestry. An analysis of homozygosity in the GS:SFHS sample revealed a very similar pattern to other European populations. We also identified an individual carrying a chromosome 1 uniparental disomy. We found evidence of local geographic stratification within the population having impact on the genomic structure. CONCLUSIONS: These findings illuminate the history of the Scottish population and have implications for further analyses such as the study of the contributions of common and rare variants to trait heritabilities and the evaluation of genomic and phenotypic prediction of disease.

Exploring the social, emotional and behavioural development of preschool children: is Glasgow different?

BACKGROUND: Glasgow City has poorer adolescent and adult health outcomes in comparison to demographically similar cities in England and the rest of Scotland. Until now, little exploration of differences in child development between Glasgow and other areas has been made. The authors hypothesized that the poorer health outcomes and lifestyle behaviours of adults, coupled with relative economic deprivation, may impact on child social, emotional and behavioural development, compared with children from other parts of Scotland. METHODS: Data from the Growing Up in Scotland national birth cohort study were used. Differences between Strengths and Difficulties Questionnaire (SDQ) scores and child and family characteristics of children living in the Greater Glasgow and Clyde (GGC) Health board vs. other health boards were examined. Logistic regression and linear regression models were fitted in order to explore independent associations between health board and SDQ raw and banded scores, respectively, whilst controlling for other contributing factors. RESULTS: Children in GGC were demographically different from those in other areas of Scotland, being significantly more likely to live in the most deprived areas, yet no difference was found in relation to the mental health of preschool-aged children in GGC. Children in GGC had slightly better SDQ Conduct Problems scores once demographic factors were controlled for. CONCLUSIONS: At 46 months, there does not appear to be any difference in Glasgow with regards to social, emotional and behavioural development. Glaswegian children appear to have slightly fewer conduct problems at this age, once demographics are taken into account. A range of theories are put forward as to why no differences were found, including the inclusion of areas adjacent to Glasgow City in the analysis, sleeper effects, and rater bias.

Policy for home or hospice as the preferred place of death from cancer: Scottish Health and Ethnicity Linkage Study population cohort shows challenges across all ethnic groups in Scotland.

BACKGROUND: Place of cancer death varies ethnically and internationally. Palliative care reviews highlight limited ability to demonstrate equal access due to incomplete or unreliable ethnicity data. AIM: To establish place of cancer death by ethnicity and describe patient characteristics. DESIGN: We linked census, hospital episode and mortality data for 117 467 persons dying of cancer, 2001-2009. With White Scottish population as reference, prevalence ratios (PR), 95% CIs and p values of death in hospital, home or hospice adjusted for sex and age were calculated by ethnic group. RESULTS: White Scottish group and minority ethnic groups combined constituted 91% and 0.4% of cancer deaths, respectively. South Asian, Chinese and African Origin patients were youngest at death (66, 66 and 65.9 years). Compared with the Scottish White reference, the White Irish (1.15 (1.10 to 1.22), p<0.0001) and Other White British (1.07 (1.02 to 1.12), p=0.003) groups were more likely to die at home. Generally, affluent Scottish White patients were less likely to die in hospital and more likely to die at home or in a hospice regardless of socioeconomic indicator used. CONCLUSIONS: Cancer deaths occur most often in hospital (52.3%) for all ethnic groups. Regardless of the socioeconomic indicator used, more affluent Scottish White patients were less likely to die in hospital; existing socioeconomic indicators detected no clear trend for the non-White population. Regardless of ethnic group, significant work is required to achieve more people dying at home or the setting of their choice.

Plasma levels of active Von Willebrand factor are increased in patients with first ST-segment elevation myocardial infarction: a multicenter and multiethnic study.

AIMS: Von Willebrand factor (VWF), a key player in hemostasis and thrombosis, is released from endothelial cells during inflammation. Upon release, VWF is processed by ADAMTS13 into an inactive conformation. The aim of our study was to investigate whether plasma levels of active VWF, total VWF, ADAMTS13, osteoprotegerin (OPG) and the ratios between VWF and ADAMTS13 are risk factors for first ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS: We assessed 1026 patients with confirmed first STEMI and 652 control subjects from China, Italy and Scotland, within six hours after their cardiovascular event. Median plasma levels of total VWF, active VWF, OPG and ratios VWF/ADAMTS13 were increased, while plasma levels of ADAMTS13 were decreased in patients compared to controls. The odds ratio (OR) of STEMI in patients with high plasma levels of active VWF was 2.3 (interquartile range (IQR): 1.8-2.9), total VWF was 1.8 (1.4-2.3), ADAMTS13 was 0.6 (05-0.8), OPG was 1.6 (1.2-2.0) and high VWF/ADAMTS13 ratios was 1.5 (1.2-2.0). The OR for total VWF, active VWF and ratios VWF/ADAMTS13 remained significant after adjustment for established risk factors, medical treatment, C-reactive protein, total VWF, ADAMTS13 and OPG. When we adjusted for levels of active VWF, the significance of the OR for VWF and ratios VWF/ADAMTS13 disappeared while the OR for active VWF remained significant. CONCLUSIONS: We found evidence that plasma levels of active VWF are an independent risk factor for first STEMI in patients from three different ethnic groups. Our findings confirm the presence of VWF abnormalities in patients with STEMI and may be used to develop new therapeutic approaches.

Racial differences in the ECG--selected aspects.

INTRODUCTION: Racial differences in the ECG have been known about for many years but there has been no significant comparison of large population groups. This study set out to remedy this shortcoming. METHODS: Digital ECG data were available for four population samples gathered in Scotland, Taiwan, Nigeria and India. All ECGs were recorded in the different countries and processed centrally by the University of Glasgow ECG Analysis Program. Measurements were analysed statistically to look for significant differences. RESULTS: There were 4223 individuals in the study (2559 males and 1664 females). In general terms, findings such as QRS duration being longer in males than females applied to all four races. More specifically, QRS voltages were higher in young black males compared to others, while ST amplitudes, as in V2, were higher in Chinese and Nigerian males than in Caucasians. CONCLUSION: Race requires to be taken into account to enhance automated interpretation of the ECG.

Attitudes of Scottish residents in the southeast of Spain concerning living donation.

BACKGROUND: To reduce the considerable organ deficit, living donation is being promoted. The subset of foreign population living in Spain could be potential patients for transplantation and/or donation. The objective of this study was to analyze the attitudes toward living donation (LD) of the population from the southeast of Spain who are natives of Scotland. MATERIALS AND METHODS: Within the "International Collaborative Donor Project," a random representative sample was obtained of the adult population residing in the southeast of Spain and who were born in Scotland (n = 350). Attitudes were evaluated with the use of a validated questionnaire that was completed anonymously and was self-administered. The Student t test, χ(2) test, and Fisher exact test were applied. RESULTS: The completion rate was 93% (n = 324); 90% of the respondents (n = 290) were in favor of related LD, decreasing to 26% (n = 85) if it was unrelated. In the analysis of variables affecting attitude toward LD, differences were found in: 1) attitude toward deceased donation (P < .001); 2) having had previous experience of the donation and transplantation process (P = .049); 3) a respondent's belief that his or her religion was in favor of LD (P < .001); and 4) a partner's attitude toward donation and transplantation (P = .007). CONCLUSIONS: The attitude toward related LD among Scottish residents in the southeast of Spain is very favorable, and is very closely related to attitude toward deceased donation, family attitude, and religious attitude. Patients on the waiting list of Scottish origin will be one of the most appropriate groups for promoting LD when living donation is being promoted in Spain.

A review of the validity and reliability of alcohol retail sales data for monitoring population levels of alcohol consumption: a Scottish perspective.

AIMS: To assess the validity and reliability of using alcohol retail sales data to measure and monitor population levels of alcohol consumption. METHODS: Potential sources of bias that could lead to under- or overestimation of population alcohol consumption based on alcohol retail sales data were identified and, where possible, quantified. This enabled an assessment of the potential impact of each bias on alcohol consumption estimates in Scotland. RESULTS: Overall, considering all the possible sources of overestimation and underestimation, and taking into account the potential for sampling variability to impact on the results, the range of uncertainty of consumption during 2010 was from an overestimate of 0.3 l to an underestimate of 2.4 l of pure alcohol per adult. This excludes the impacts of alcohol stockpiling and alcohol sold through outlets not included in the sampling frame. On balance, there is therefore far greater scope for alcohol retail sales data to be underestimating per adult alcohol consumption in Scotland than there is for overestimation. CONCLUSION: Alcohol retail sales data offer a robust source of data for monitoring per adult alcohol consumption in Scotland. Consideration of the sources of bias and a comprehensive understanding of data collection methods are essential for using sales data to monitor trends in alcohol consumption.

Profiles of physical, emotional and psychosocial wellbeing in the Lothian birth cohort 1936.

BACKGROUND: Physical, emotional, and psychosocial wellbeing are important domains of function. The aims of this study were to explore the existence of separable groups among 70-year olds with scores representing physical function, perceived quality of life, and emotional wellbeing, and to characterise any resulting groups using demographic, personality, cognition, health and lifestyle variables. METHODS: We used latent class analysis (LCA) to identify possible groups. RESULTS: Results suggested there were 5 groups. These included High (n = 515, 47.2% of the sample), Average (n = 417, 38.3%), and Poor Wellbeing (n = 37, 3.4%) groups. The two other groups had contrasting patterns of wellbeing: one group scored relatively well on physical function, but low on emotional wellbeing (Good Fitness/ Low Spirits,n = 60, 5.5%), whereas the other group showed low physical function but relatively well emotional wellbeing (Low Fitness/Good Spirits, n = 62, 5.7%). Salient characteristics that distinguished all the groups included smoking and drinking behaviours, personality, and illness. CONCLUSIONS: Despite there being some evidence of these groups, the results also support a largely one-dimensional construct of wellbeing in old age--for the domains assessed here--though with some evidence that some individuals have uneven profiles.

Declining suburbs in Europe and Latin America.

Suburban shrinkage, understood as a degenerative urban process stemming from the demise of the Fordist mode of urbanism, is generally manifested in a decline in population, industry and employment. It is also intimately linked to the global restructuring of industrial organization associated with the rise of the post-Fordist mode of urbanism and, more recently, the thrust of Asian industrialization. Framed in the discourse of industrial urbanism, this article examines the first ring of industrial suburbs that developed around large cities in their most rapid Fordist urbanization phase. These industrial suburbs, although they were formed at different times, are today experiencing specific mutations and undergoing profound restructuring on account of their particular spatial position between the central area and the expanding peripheries of the post-Fordist metropolis. This article describes and compares suburban decline in two European cities (Glasgow and Paris) and two Latin American Cities (São Paulo, Brazil and Guadalajara, Mexico), as different instances of places asymmetrically and fragmentarily integrated into the geography of globalization.

Genome-wide homozygosity and multiple sclerosis in Orkney and Shetland Islanders.

There is strong evidence for both genetic and environmental risk factors comprising the aetiology of multiple sclerosis (MS). While much progress has been made in recent years in identifying common genetic variants using genome-wide association studies, alternative approaches have remained relatively neglected. The prevalence of MS in Orkney and Shetland is among the highest in the world. Previous studies have suggested that a higher degree of parental relatedness in these isolated communities may contribute to the high rates of MS, indicating that recessive effects have an important role in MS aetiology. The Northern Isles Multiple Sclerosis (NIMS) study investigated the potential role of genome-wide homozygosity in MS risk by genotyping 88 MS patients, 89 controls matched by age, sex and ancestry, and a further 89 controls matched for sex and ancestry, but passed the majority of lifetime risk of developing MS (>70 years of age). Three participants were removed on the basis of pedigree-genomic anomalies (n=263). Three measures of genome-wide homozygosity were generated for each individual, and association with MS was assessed using logistic regression models. No effect of genome-wide homozygosity was detected, indicating that inbreeding and consanguinity are not risk factors for MS in this population.

Intimacy and the life cycle in the marital relationships of the Scottish elite during the long eighteenth century.

Traditionally marriage has been treated as one step in the life cycle, between youth and old age, singleness and widowhood. Yet an approach to the life cycle that treats marriage as a single step in a person's life is overly simplistic. During the eighteenth century many marriages were of considerable longevity during which time couples aged together and power dynamics within the home were frequently renegotiated to reflect changing circumstances. This study explores how intimacy developed and changed over the life cycle of marriage and what this meant for power, through a study of the correspondence of two elite Scottish couples.

"Children of the city": juvenile justice, property, and place in England and Scotland, 1945-60.

This article uses cases studies of Dundee and Manchester to explain juvenile property-offending in terms of young people's use of objects and spaces in the period 1945-60. A composite picture is assembled of objects stolen, which reflects growth of the specifically "teenage" consumer market as well as continued significance of young people's contribution to family economies. Concerns about youth, property, and space were reported in newspapers in terms of vandalism and hooliganism. "Play" and "nuisance" were overlapping and contested categories; re-education of young people in the correct use of place, space, and property was a key aim of the postwar juvenile justice system.

Edward Forbes (1815-1854) and the exhibition of natural order in Edinburgh.

The roles, affordances and social agency of natural history museums are discussed in relation to the writings of Edward Forbes. These signal a motivation, in the mid-nineteenth-century, to naturalize the established social order through the systematic arrangement and display of natural history specimens. The perceived importance of the embodied messages of social order, as an antidote to radicalism and revolution, overrode concerns about temperance and abstinence and immediate fears for the physical safety of collections. The tensions between temperance, and the broader concerns about social order, were played out over the matter of the museums themselves being licensed premises.

Identification of high risk DISC1 protein structural variants in patients with bipolar spectrum disorder.

In a large Scottish pedigree, a balanced translocation t (1;11)(q42.1;q14.3) disrupting the DISC1 and DISC2 genes segregates with major mental illness, including schizophrenia and depression. A frame-shift carboxyl-terminal deletion was reported in DISC1 in an American family with schizophrenia, but subsequently found in two controls. Herein, we test one hypothesis utilizing a large scale case-control mutation analysis: uncommon DISC1 variants are associated with high risk for bipolar spectrum disorder. We have analyzed the regions of likely functional significance in the DISC1 gene in 504 patients with bipolar spectrum disorder and 576 ethnically similar controls. Five patients were heterozygous for ultra-rare protein structural variants not found in the 576 controls (p=0.02, one-sided Fisher's exact test) and shown to be ultra-rare by their absence in a pool of 10,000 control alleles. In our sample, ultra-rare (private) protein structural variants in DISC1 are associated with an estimated attributable risk of about 0.5% in bipolar spectrum disorder. These data are consistent with: (i) the high frequency of depression in the large Scottish family with a translocation disrupting DISC1; (ii) linkage disequilibrium analysis demonstrating haplotypes associated with relatively small increases in risk for bipolar disorder (<3-fold odds ratio). The data illustrate how low/moderate risk haplotypes that might be found by the HapMap project can be followed up by resequencing to identify protein structural variants with high risk, low frequency and of potential clinical utility.

Mortality for alcohol-related harm by country of birth in Scotland, 2000-2004: potential lessons for prevention.

AIMS: Deaths caused by alcohol have increased in the UK, and Scotland in particular, but the change in the rates of alcohol-related deaths for migrants are uncertain, and could yield insights for the general population. METHODS: Alcohol-related mortality in immigrants among Scotland's residents was assessed using 2001 census data and mortality data from 2000 to 2004. RESULTS: Mortality from direct alcohol-related causes accounted for nearly 1500 deaths per year in Scotland. Age-standardized mortality ratios were comparatively low for people born in Pakistan, other parts of the UK (largely England and Wales) and those from elsewhere in the world. CONCLUSIONS: Scotland's propensity to alcohol-related deaths is not shared by all its residents. Studying such variations in more depth could yield lessons for prevention.
