Trends in premature mortality due to ischemic heart disease in Spain from 1998 to 2018.

INTRODUCTION AND OBJECTIVES: Ischemic heart disease (IHD) is the leading cause of death and one of the leading causes of disability. The aim of this study was to analyze trends in premature mortality due to IHD in patients younger than 75 years in Spain from 1998 to 2018 by region. METHODS: Observational study of temporal trends in premature mortality due to IHD in Spain by region and sex from 1998 to 2018. The study population included resident citizens aged between 0 and 74 years. The data sources were the continuous population register and the mortality registry of the National Institute of Statistics. We calculated age-adjusted mortality rates and their average annual percent change estimated by Poisson models. RESULTS: During the study period, mortality rates due to IHD decreased, both in the country as a whole and by provinces (53% in men and 61% in women), with an average annual percent change of -3.92% and -5.07%, respectively. In the first year (1998), mortality was unequally distributed among provinces, with higher mortality in the south of Spain. CONCLUSIONS: Premature mortality due to IHD significantly decreased in Spain during the study period in both sexes to roughly half of initial cases. This decrease was statistically significant in almost all regions. Interprovincial differences in mortality and their variation also decreased in recent years.

Environmental factors modulated ancient mitochondrial DNA variability and the prevalence of rheumatic diseases in the Basque Country.

Among the factors that would explain the distribution of mitochondrial lineages in Europe, climate and diseases may have played an important role. A possible explanation lies in the nature of the mitochondrion, in which the energy generation process produces reactive oxygen species that may influence the development of different diseases. The present study is focused on the medieval necropolis of San Miguel de Ereñozar (13th-16th centuries, Basque Country), whose inhabitants presented a high prevalence of rheumatic diseases and lived during the Little Ice Age (LIA). Our results indicate a close relationship between rheumatic diseases and mitochondrial haplogroup H, and specifically between spondyloarthropathies and sub-haplogroup H2. One possible explanation may be the climate change that took place in the LIA that favoured those haplogroups that were more energy-efficient, such as haplogroup H, to endure lower temperatures and food shortage. However, it had a biological trade-off: the increased risk of developing rheumatic diseases.

The mitogenome of a 35,000-year-old Homo sapiens from Europe supports a Palaeolithic back-migration to Africa.

After the dispersal of modern humans (Homo sapiens) Out of Africa, hominins with a similar morphology to that of present-day humans initiated the gradual demographic expansion into Eurasia. The mitogenome (33-fold coverage) of the Pestera Muierii 1 individual (PM1) from Romania (35 ky cal BP) we present in this article corresponds fully to Homo sapiens, whilst exhibiting a mosaic of morphological features related to both modern humans and Neandertals. We have identified the PM1 mitogenome as a basal haplogroup U6*, not previously found in any ancient or present-day humans. The derived U6 haplotypes are predominantly found in present-day North-Western African populations. Concomitantly, those found in Europe have been attributed to recent gene-flow from North Africa. The presence of the basal haplogroup U6* in South East Europe (Romania) at 35 ky BP confirms a Eurasian origin of the U6 mitochondrial lineage. Consequently, we propose that the PM1 lineage is an offshoot to South East Europe that can be traced to the Early Upper Paleolithic back migration from Western Asia to North Africa, during which the U6 lineage diversified, until the emergence of the present-day U6 African lineages.

[Vascular tumors as syndromic indicators]. / Tumores vasculares como marcadores sindrómicos.

Haemangiomas can be indicators or clue signs for serious syndromes. Although less well known than those related to vascular malformations, there are some syndromes of important diagnostic value that are associated with haemangomias. Early recognition of problematic haemangiomas, together with a prompt intervention, may help to minimise their future morbidity. Neonatal haemangiomas warrant a special follow-up, since their growth pattern might be unpredictable at such an early age. Several clinical presentations are relevant because of their risk of syndromic association: cervicofacial haemangiomas, especially the extensive ones, may be markers for severe dysmorphic conditions like the PHACE(S) syndrome. Those distributed in the beard area are occasionally associated with haemangiomas of the airway. Lumbosacral haemangiomas usually hide an underlying spinal dysraphism or anorectal and urogenital anomalies. Multiple cutaneous haemangiomas may be a sign of visceral haemangiomatosis, most often hepatic, which becomes complicated by cardiac insufficiency or thyroid disease. Finally, there are two vascular neoplasms of rapid and invasive growth - kaposiform haemangioendothelioma and angioblastoma or tufted angioma - which, unlike infantile haemangioma, are markers for the Kasabach-Merritt syndrome.

Los hemangiomas pueden ser marcadores o signos guía de síndromes graves. Aunque menos conocidos que los relacionados con malformaciones vasculares, existen algunos síndromes de importante valor diagnóstico que se asocian a hemangiomas. El reconocimiento precoz de los hemangiomas de alto riesgo, junto a una rápida actuación, puede ayudar a minimizar su morbilidad futura. Los hemangiomas en neonatos requieren un seguimiento especial, debido a que su patrón de crecimiento puede ser imprevisible a una edad tan temprana. Diversas presentaciones clínicas son relevantes por su riesgo de asociación sindrómica: los hemangiomas cervicofaciales, especialmente los de gran tamaño, pueden ser marcadores de trastornos dismórficos graves como el síndrome PHACE(S). Los que se distribuyen en el área de la barba se asocian en ocasiones a hemangiomas de la vía aérea. Los hemangiomas lumbosacros suelen ocultar un disrafismo espinal o malformaciones anorrectales y urogenitales. Los hemangiomas cutáneos múltiples pueden ser signo de una hemangiomatosis visceral, con más frecuencia hepática, que se complique con insuficiencia cardíaca o enfermedad tiroidea. Por último, existen dos neoplasias vasculares de crecimiento rápido e invasor, distintas del hemangioma del lactante (el hemangioendotelioma kaposiforme y el angioblastoma o hemangioma "en penachos"), que son marcadores del síndrome de Kasabach-Merritt (AU)

Postmenopausal frontal fibrosing alopecia.

Recently a new entity, postmenopausal frontal fibrosing alopecia, was added to the established subtypes of scarring alopecias affecting postmenopausal women. This condition is characterized by a progressive frontal hairline recession associated with scarring. We studied the clinical and histopathologic features in four women with this disorder. Of note, a history of bilateral oophorectomy in two of them appears to be a new association. All four cases had frontoparietal recession of the hairline and two of them also had loss of their eyebrows. None of our four patients had any mucous membrane or other skin lesions. Histological examination showed perifollicular fibrosis and lymphocytic inflammation around the isthmus and infundibular areas of the follicles. No effective treatments have emerged for this type of postmenopausal alopecia, but progression of the hair loss and scarring appears to be self-limiting. We believe that this condition is a distinct clinicopathological variant of lichen planopilaris.
