Abstract

Genome-wide association studies have discovered hundreds of loci associated with complex brain disorders, but it remains unclear in which cell types these loci are active. Here we integrate genome-wide association study results with single-cell transcriptomic data from the entire mouse nervous system to systematically identify cell types underlying brain complex traits. We show that psychiatric disorders are predominantly associated with projecting excitatory and inhibitory neurons. Neurological diseases were associated with different cell types, which is consistent with other lines of evidence. Notably, Parkinson’s disease was genetically associated not only with cholinergic and monoaminergic neurons (which include dopaminergic neurons) but also with enteric neurons and oligodendrocytes. Using post-mortem brain transcriptomic data, we confirmed alterations in these cells, even at the earliest stages of disease progression. Our study provides an important framework for understanding the cellular basis of complex brain maladies, and reveals an unexpected role of oligodendrocytes in Parkinson’s disease. © 2020, The Author(s), under exclusive licence to Springer Nature America, Inc.

Abstract

Blood pressure (BP) was inconsistently associated with migraine and the mechanisms of BP-lowering medications in migraine prophylaxis are unknown. Leveraging large-scale summary statistics for migraine (Ncases/Ncontrols = 59,674/316,078) and BP (N = 757,601), we find positive genetic correlations of migraine with diastolic BP (DBP, rg = 0.11, P = 3.56 × 10−06) and systolic BP (SBP, rg = 0.06, P = 0.01), but not pulse pressure (PP, rg = −0.01, P = 0.75). Cross-trait meta-analysis reveals 14 shared loci (P ≤ 5 × 10−08), nine of which replicate (P < 0.05) in the UK Biobank. Five shared loci (ITGB5, SMG6, ADRA2B, ANKDD1B, and KIAA0040) are reinforced in gene-level analysis and highlight potential mechanisms involving vascular development, endothelial function and calcium homeostasis. Mendelian randomization reveals stronger instrumental estimates of DBP (OR [95% CI] = 1.20 [1.15–1.25]/10 mmHg; P = 5.57 × 10−25) on migraine than SBP (1.05 [1.03–1.07]/10 mmHg; P = 2.60 × 10−07) and a corresponding opposite effect for PP (0.92 [0.88–0.95]/10 mmHg; P = 3.65 × 10−07). These findings support a critical role of DBP in migraine susceptibility and shared biology underlying BP and migraine.

Abstract

Studies of random isonymy in historical populations have relied upon two different types of data: census records and marriage records. Censuses, as well as tax lists, militia rolls, and other directories, sample a single moment in time. Marriage registers provide a list of couples over a period of time. The first has the advantage of synchronicity and completeness; the second of equal representation of males and females. Few studies have used both methods, so their relationship is unclear. In the United States, historical studies of Massachusetts populations have used marriage records, while others of Pennsylvania and New York have used censuses. To compare the methods, records spanning the years 1795-1859 were examined from three counties in Georgia: Bulloch, Camden, and Tatnall. [I.sub.ii] was calculated for each county from each decennial census and from three different arrangements of marriage records. First, each census was compared with a ten-year span of marriages centered on that date (N = 14), and then with the spans before (N = 13) and after (N = 14) it. All three correlations were strong (r [is greater than] 0.8); the strongest was that between marriages and midpoint censuses. When separate lists of male and female names were derived from the marriage registers, female [I.sub.ii] exhibited a slightly greater correlation with census [I.sub.ii], despite the fact that these censuses only record male heads of household. This indicates that patterns of male and female marital migration were not different enough to invalidate calculations based solely upon the male names in the census. Values of [I.sub.ii] steadily increase over the period studied. The 1805 and 1810 samples represent first and second generation migrants; by 1850, population structure had had one or two more generations to develop. The highest values of [I.sub.ii] reach 0.012, higher than has been reported from western Pennsylvania in 1800, but lower than 18th century Brooklyn, New York. This follows what is known about the culture history of these populations: Antebellum Georgia was less culturally and ethnically diverse than early Pennsylvania, but far more so than the homogeneous Dutch settlements of western Long Island.

Abstract

Migraine is a debilitating neurological disorder affecting around one in seven people worldwide, but its molecular mechanisms remain poorly understood. There is some debate about whether migraine is a disease of vascular dysfunction or a result of neuronal dysfunction with secondary vascular changes. Genome-wide association (GWA) studies have thus far identified 13 independent loci associated with migraine. To identify new susceptibility loci, we carried out a genetic study of migraine on 59,674 affected subjects and 316,078 controls from 22 GWA studies. We identified 44 independent single-nucleotide polymorphisms (SNPs) significantly associated with migraine risk (P < 5 × 10-8) that mapped to 38 distinct genomic loci, including 28 loci not previously reported and a locus that to our knowledge is the first to be identified on chromosome X. In subsequent computational analyses, the identified loci showed enrichment for genes expressed in vascular and smooth muscle tissues, consistent with a predominant theory of migraine that highlights vascular etiologies.

Abstract

Estimates of the magnitude of early colonial indigenous population decline in Mesoamerica range from 25% to 90%. Because detailed mortality reports do not exist for sixteenth-century epidemics, scholars rely upon general descriptions of their extent, as well as modern epidemiological accounts of the diseases that may have been responsible. Eighteenth-century epidemics can be studied in greater detail. One of the most destructive was the matlazahuatl epidemic which raged across Mexico between 1736 and 1738. Contemporary accounts report 40,000 deaths in Mexico City alone. The name matlazahuatl was also used to describe an earlier pandemic in 15761580. What pathogen was responsible? Typhus, plague, smallpox, and most recently ah arenaviral hemorrhagic fever have been proposed. The parish records of Mixquiahuala and Tecpatepec, Hidalgo, Mexico include burial records from 1737-1738, which can be tied to a 1718 nominal census as well as birth and marriage registers. Family reconstruction indicates that the causative agent was regularly spread by interpersonal contact between immediate family members. Over the 15 month span of the epidemic in these towns, 218 people were buried in Mixquiahuala and 380 in Tecpatepec. If we assume no change in population size between 1718 and 1737, this indicates a mortality of 53% and 57%. In Mixquiahuala, 95 unmarried and 123 married individuals died, equivalent to 52% and 54% of the 1718 population in each category, and in Tecpatepec 194 and 186 died, or 54% and 61%. The high mortality and familial transmission suggest that neither typhus nor a zoonotic hemorrhagic fever was responsible.

Abstract

PURPOSE: This study was designed to evaluate the interobserver and intraobserver agreement of two-dimensional (2-D) and three-dimensional (3-D) anal endosonography for the detection of local recurrence anal carcinoma. METHODS: Thirty-six patients were treated for anal carcinoma, and seven had recurrent disease. They were investigated by using 3-D endosonography at Rigshospitalet from July 2001 to January 2005 because of suspected local recurrence. The 3-D endosonographic examinations were reviewed from the hard disc by two observers who twice reviewed all 2-D examinations (the axial projection) as well as all 3-D examinations (the axial, as well as the reconstructed coronal and sagittal projections). The observers scored each examination according to the following scale regarding presence of local recurrence: 1 = no finding/benign findings; 2 = properly benign findings; 3 = suspicious findings/malignant findings. Kappa statistic-statistic was used to evaluate interobserver and intraobserver variation. RESULTS: Three-dimensional endosonography achieved better interobserver agreement than 2-D endosonography: kappa 3-D 0.34-047 vs. kappa 2-D 0.15-0.28 and better intraobserver agreement: kappa 3-D 0.34-0.62 vs. kappa 2-D 0.22-0.28. These differences showed P < 0.05. CONCLUSIONS: Three-dimensional endosonography proved to have significantly better interobserver and intraobserver agreement than 2-D endosonography concerning detection of recurrent anal cancer. Three-dimensional endosonography seems to be less dependent of the individual examiner than 2-D endosonography Udgivelsesdato: 2009/3
