Worldwide trends in gastric cancer mortality (1980-2011), with predictions to 2015, and incidence by subtype.

Gastric cancer incidence and mortality decreased substantially over the last decades in most countries worldwide, with differences in the trends and distribution of the main topographies across regions. To monitor recent mortality trends (1980-2011) and to compute short-term predictions (2015) of gastric cancer mortality in selected countries worldwide, we analysed mortality data provided by the World Health Organization. We also analysed incidence of cardia and non-cardia cancers using data from Cancer Incidence in Five Continents (2003-2007). The joinpoint regression over the most recent calendar periods gave estimated annual percent changes (EAPC) around -3% for the European Union (EU) and major European countries, as well as in Japan and Korea, and around -2% in North America and major Latin American countries. In the United States of America (USA), EU and other major countries worldwide, the EAPC, however, were lower than in previous years. The predictions for 2015 show that a levelling off of rates is expected in the USA and a few other countries. The relative contribution of cardia and non-cardia gastric cancers to the overall number of cases varies widely, with a generally higher proportion of cardia cancers in countries with lower gastric cancer incidence and mortality rates (e.g. the USA, Canada and Denmark). Despite the favourable mortality trends worldwide, in some countries the declines are becoming less marked. There still is the need to control Helicobacter pylori infection and other risk factors, as well as to improve diagnosis and management, to further reduce the burden of gastric cancer.

A comparison of trends in mortality from primary liver cancer and intrahepatic cholangiocarcinoma in Europe.

BACKGROUND: To update and compare mortality from primary liver cancer (PLC) and intrahepatic cholangiocarcinoma (ICC) in Europe in 1990-2010. MATERIALS AND METHODS: We used data from the World Health Organization (WHO) to compute age-standardized (world population) mortality rates, and used joinpoint analysis to identify substantial changes. RESULTS: Between 2002 and 2007, PLC rates in the European Union (EU) declined from 3.9 to 3.6/100,000 men. Around 2007, the highest male rates were in France (6.2/100,000), Spain (4.9), and Italy (4.0), while the lowest ones were in Sweden (1.1), the Netherlands (1.2), and the UK (1.8). In women, mortality was lower (0.8/100,000 in 2007 in the EU), and showed more favourable trends, with a decline of over 2% per year over the last two decades as compared with 0.4% in men, in the EU. In contrast, the EU mortality from ICC increased by around 9% in both sexes from 1990 to 2008, reaching rates of 1.1/100,000 men and 0.75/100,000 women. The highest rates were in UK, Germany, and France (1.2-1.5/100,000 men, 0.8-1.1/100,000 women). CONCLUSIONS: PLC mortality has become more uniform across Europe over recent years, with an overall decline; in contrast, ICC mortality has substantially increased in most Europe.

Incidence and mortality from non-Hodgkin lymphoma in Europe: the end of an epidemic?

Non-Hodgkin lymphomas (NHL) are among the few neoplasms whose incidence and mortality have been rising in Europe and North America over the last few decades. To update trends from NHL, we considered mortality data up to 2004 in several European countries, and for comparative purpose in the USA and Japan. We also analyzed patterns in incidence for selected European countries providing national data. In most European countries, NHL mortality rose up to the mid 1990s, and started to level off or decline in the following decade. The rates were, however, still increasing in eastern Europe. Overall, in the European Union, mortality from NHL declined from 4.3/100,000 to 4.1 in men and from 2.7 to 2.5 in women between the late 1990s and the early 2000s. Similarly, NHL mortality rates declined from 6.5/100,000 to 5.5 in US men and from 4.2 to 3.5 in US women. In most countries considered, NHL incidence rates rose up to 1995-99, while they tended to level off or decline thereafter, with particular favorable patterns in countries from northern Europe. Thus, the epidemic of NHL observed during the second half of the 20th century has now started to level off in Europe as in other developed areas of the world.

Atributos Físicos de um Cambissolo Cultivado e Tratado com Biofertilizante na Chapada do Apodi, Ceará

O conhecimento sobre as alterações físicas e qualidade do solo é importante para o direcionamento adequado das estratégias de manejo a serem utilizadas quando da exploração do solo por cultivos agrícolas. Este trabalho teve como objetivo avaliar os efeitos do cultivo e da aplicação de um biofertilizante, obtido a partir de esterco bovino, sobre a qualidade física de um Cambissolo cultivado com Ficus carica L., irrigado por sistema de gotejamento. Para fins de avaliação da qualidade física, foram contempladas cinco situações de solo: sob cultivo de figo sem aplicação do biofertilizante (testemunha); com aplicação de 20, 40 e 60 % do biofertilizante na lâmina de irrigação; e mata nativa secundária (testemunha adicional), até a profundidade de 0,3 m, nas camadas de 0,0-0,1, 0,1-0,2; e 0,2-0,3 m, com quatro repetições. Nessas camadas, foram coletadas amostras de solo com estrutura deformada e indeformada para realizar análises físicas, como granulometria, argila dispersa em água, carbono orgânico, densidade das partículas e do solo, resistência do solo à penetração e curva característica de água no solo. O cultivo do solo nas condições descritas nesta pesquisa, como preparo do solo por aração e gradagem, uso de irrigação e todos os tratos culturais necessários à condução da cultura de figo, não piora a qualidade física do solo em nenhuma das camadas avaliadas. A aplicação de biofertilizante melhora a qualidade física do solo, particularmente no tocante à retenção de água em decorrência do aumento da microporosidade.

Estimating and explaining the effect of education and income on head and neck cancer risk : INHANCE consortium pooled analysis of 31 case-control studies from 27 countries

Low socioeconomic status has been reported to be associated with head and neck cancer risk. However, previous studies have been too small to examine the associations by cancer subsite, age, sex, global region, and calendar time, and to explain the association in terms of behavioural risk factors. Individual participant data of 23,964 cases with head and neck cancer and 31,954 controls from 31 studies in 27 countries pooled with random effects models. Overall, low education was associated with an increased risk of head and neck cancer (OR = 2·50; 95%CI 2·02- 3·09). Overall one-third of the increased risk was not explained by differences in the distribution of cigarette smoking and alcohol behaviours; and it remained elevated among never users of tobacco and non-drinkers (OR = 1·61; 95%CI 1·13 - 2·31). More of the estimated education effect was not explained by cigarette smoking and alcohol behaviours: in women than in men, in older than younger groups, in the oropharynx than in other sites, in South/Central America than in Europe/North America, and was strongest in countries with greater income inequality. Similar findings were observed for the estimated effect of low vs high household income. The lowest levels of income and educational attainment were associated with more than 2-fold increased risk of head and neck cancer, which is not entirely explained by differences in the distributions of behavioural risk factors for these cancers, and which varies across cancer sites, sexes, countries, and country income inequality levels. © 2014 Wiley Periodicals, Inc.

Trends in mortality from urologic cancers in Europe, 1970-2008.

BACKGROUND: In recent decades, there have been substantial changes in mortality from urologic cancers in Europe. OBJECTIVE: To provide updated information, we analyzed trends in mortality from cancer of the prostate, testis, bladder, and kidney in Europe from 1970 to 2008. DESIGN, SETTING, AND PARTICIPANTS: We derived data for 33 European countries from the World Health Organization database. MEASUREMENTS: We computed world-standardized mortality rates and used joinpoint regression to identify significant changes in trends. RESULTS AND LIMITATIONS: Mortality from prostate cancer has leveled off since the 1990s in countries of western and northern Europe, particularly over the last few years while it was still rising in Bulgaria, Romania, and Russia. In the European Union (EU), it reached a peak in 1995 at 15.0 per 100 000 men and declined to 12.5 per 100 000 in 2006. Mortality from testicular cancer has steadily declined in most countries in western and northern Europe since the 1970s. The declines were later and appreciably lower in central/eastern Europe. In EU, rates declined from 0.75 in 1980 to 0.32 per 100 000 men in 2006, with stronger declines up to the late 1990s and an apparent leveling off in rates thereafter. Over the last 15 years, mortality from bladder cancer has declined in most European countries in both sexes. The major exceptions were Bulgaria, Poland, and Romania. In the EU, bladder cancer mortality was stable until 1992 and declined thereafter from 7.3 to 5.5 per 100 000 men and from 1.5 to 1.2 per 100 000 women in 2006. Mortality from kidney cancer increased throughout Europe until the early 1990s and leveled off thereafter in many countries, except in a few central and eastern ones. Between 1994 and 2006, rates declined from 4.9 to 4.3 per 100 000 in EU men and from 2.1 to 1.8 per 100 000 in EU women. CONCLUSIONS: Over the last two decades, trends in urologic cancer mortality were favorable in Europe, with the exception of a few central and eastern countries.

ORMDL proteins are a conserved new family of endoplasmic reticulum membrane proteins

Background: Annotations of completely sequenced genomes reveal that nearly half of the genes identified are of unknown function, and that some belong to uncharacterized gene families. To help resolve such issues, information can be obtained from the comparative analysis of homologous genes in model organisms. Results: While characterizing genes from the retinitis pigmentosa locus RP26 at 2q31-q33, we have identified a new gene, ORMDL1, that belongs to a novel gene family comprising three genes in humans (ORMDL1, ORMDL2 and ORMDL3), and homologs in yeast, microsporidia, plants, Drosophila, urochordates and vertebrates. The human genes are expressed ubiquitously in adult and fetal tissues. The Drosophila ORMDL homolog is also expressed throughout embryonic and larval stages, particularly in ectodermally derived tissues. The ORMDL genes encode transmembrane proteins anchored in the endoplasmic reticulum (ER). Double knockout of the two Saccharomyces cerevisiae homologs leads to decreased growth rate and greater sensitivity to tunicamycin and dithiothreitol. Yeast mutants can be rescued by human ORMDL homologs. Conclusions: From protein sequence comparisons we have defined a novel gene family, not previously recognized because of the absence of a characterized functional signature. The sequence conservation of this family from yeast to vertebrates, the maintenance of duplicate copies in different lineages, the ubiquitous pattern of expression in human and Drosophila, the partial functional redundancy of the yeast homologs and phenotypic rescue by the human homologs, strongly support functional conservation. Subcellular localization and the response of yeast mutants to specific agents point to the involvement of ORMDL in protein folding in the ER.
