    Full Text Available The underlying reasons for the increasing occurrence of male reproductive diseases (MRD such as hypospadias, cryptorchidism, and testicular cancer (TC over the last decades are still unknown. It has been hypothesized that the risk of MRD is determined in utero and that pregnancy dietary intake could also affect MRD risk in the offspring. Various studies in animals reported that cocoa and theobromine, the main stimulant of cocoa, exert toxic effects on the testis, inducing testicular atrophy and impaired sperm quality. A correlation analysis was conducted to examine the possible role of cocoa consumption on the occurrence of selected MRD during the prenatal and early life period of cases. The incidence rates between 1998-2002 of TC in 18 countries obtained from Cancer Incidence in Five Continents were correlated with the average per-capita consumption of cocoa (kg/capita/year (FAOSTAT-Database in these countries from 1965 to 1980, i.e. the period corresponding to the early life of TC cases. In order to test the above correlation in the case of hypospadias, the mean prevalence at birth in 20 countries (1999-2003 with average per-capita consumption of cocoa in these countries in the same period corresponding to pregnancy were used. The consumption of cocoa in the period 1965–80, was most closely correlated with the incidence of TC in young adults (r=0.859; p<0.001. An analogous significant correlation was also observed between early cocoa consumption and the prevalence rates of hypospadias in the period 1999-2003 (r=0.760; p<0.001. Although the ecological approach used in this study cannot provide an answer on the causal relationship between consumption of cocoa in early life and TC and hypospadias, the results are suggestive and indicate the need of further analytic studies to investigate the role of individual exposure to cocoa, particularly during the prenatal and in early life of the patients.

    The incidence and mortality trends of oesophageal cancer are changing significantly across the world with considerable heterogeneity between sex, histological types, ethnic patterns and geographical distribution. Recent oesophageal cancer incidence and mortality trends have been analysed using data available from the WHO mortality database, the GLOBOCAN 2012 database and the Cancer Incidence in Five Continents database managed by the International Agency for Research on Cancer. Huge geographical variation is an epidemiological characteristic of oesophageal cancer, with the highest incidence rates observed in Eastern Asia and in Eastern and Southern Africa and the lowest rates observed in Western Africa. The variation is to the order of more than 21 times between the lowest-incidence and the highest-incidence countries. Although the incidence of squamous cell carcinoma is increasing globally, its incidence rates are decreasing in the USA and a few European countries. However, the decrease in the incidence of squamous cell carcinomas in these countries has been accompanied by a marked increase in adenocarcinoma incidence rates. There is a significant sex variation as well, with men being affected three to four times more commonly than women worldwide. The observed trends reflect significant global variations in the incidence and mortality of oesophageal cancers on the basis of sex, geographical distribution, ethnicity and histology. These epidemiological factors related to oesophageal cancers point out a possibly significant role of molecular epidemiological factors (genetic susceptibility and response to treatment) with major differences likely between the characteristics of Asian and Western populations.

    Abstract Background: To assess the worldwide variation of amyotrophic lateral sclerosis (ALS) incidence, we performed a systematic review and meta-analysis of population-based data published to date. Methods: We reviewed Medline and Embase up to June 2015 and included all population-based studies of newly diagnosed ALS cases, using multiple sources for case ascertainment. ALS crude and standardized incidence (on age and sex using the US 2010 population) were calculated. Random effect meta-analysis and meta-regression were performed using the subcontinent as the main study level covariate. Sources of heterogeneity related to the characteristics of the study population and the study methodology were investigated. Results: Among 3216 records, 44 studies were selected, covering 45 geographical areas in 11 sub-continents. A total of 13 146 ALS cases and 825 million person-years of follow-up (PYFU) were co-nsidered. The overall pooled worldwide crude ALS incidence was at 1.75 (1.55–1.96)/100 000 PYFU; 1.68 (1.50–1.85)/100 000 PYFU after standardization. Heterogeneity was identified in ALS standardized incidence between North Europe [1.89 (1.46–2.32)/100 000 PYFU] and East Asia [0.83 (0.42–1.24)/100 000 PYFU, China and Japan P = 0.001] or South Asia [0.73 (0.58–0.89)/100 000/PYFU Iran, P = 0.02]. Conversely, homogeneous rates have been reported in populations from Europe, North America and New Zealand [pooled ALS standardized incidence of 1.81 (1.66-1.97)/100 000 PYFU for those areas]. Conclusion: This review confirms a heterogeneous distribution worldwide of ALS, and sets the scene to sustain a collaborative study involving a wide international consortium to investigate the link between ancestry, environment and ALS incidence.

    While all patients with epilepsy experience seizures, not all individuals with seizures have epilepsy. Seizures may be acute symptomatic or unprovoked. Acute symptomatic seizures are seizures occurring at the time of a systemic insult or in close temporal association with a documented brain insult. Unprovoked seizures are seizures occurring in the absence of precipitating factors and may be caused by a static injury (remote symptomatic seizures) or a progressing injury (progressive symptomatic seizures). Unprovoked seizures may be single or recurrent (epilepsy). The incidence of acute symptomatic seizures is 29-39 per 100,000 per year. These predominate in men, in the youngest age class, and in the elderly. Traumatic brain injury, cerebrovascular disease, drug withdrawal, infarction, and metabolic insults are the commonest causes. The incidence of single unprovoked seizures is 23-61 per 100,000 person-years. As with epilepsy, single unprovoked seizures predominate in men and in patients less than 12 months and older than 65 years. Studies on the mortality of acute symptomatic seizures are lacking. A standardized mortality ratio (SMR) of 2.3 has been reported in patients experiencing a single unprovoked seizure. The SMR in patients with a newly diagnosed unprovoked seizure ranges from 2.5 to 4.1 according to the study population and design. The SMR is highest in the youngest patients and in those with symptomatic seizures.

    Full Text Available Background Infant mortality rate (per 1000 live births is a vital index to monitor the standard of health and social inequality which is related to human development dimensions worldwide. Human development index (HDI includes basic social indicators such as life expectancy, education and income. Objectives The current study aimed to find the correlation between human development index and infant mortality rate. Patients and Methods This descriptive study that represents the relationship of infant mortality rate with human development index and human development index dimensions was performed on the profiles of 135 countries worldwide [Africa (35 countries, America (26 countries, Asia (30 countries, the Pacific (2 countries and Europe (42 countries]. Two databases were used in the study: the world health organization (WHO database (2010 and human development database (2010. Data were analyzed using Pearson correlation test by SPSS software. Results The study found that socio-economic factors or human development dimensions are significantly correlated with risk of chance mortality in the world. The per capita income (r = -0.625, life expectancy (r = -0.925 and education (r = -0.843 were negatively correlated with the infant mortality rate; human development index (r = -0.844 was also negatively correlated with the infant mortality rate (P < 0.01. Conclusions Human development index is one of the best indicators and predictors to perceive healthcare inequities. Worldwide improvement of these indicators, especially the education level, might promote infant life expectancy and decrease infant mortality.

    The aim of this study was to evaluate the incidence and mortality of prostate cancer and their relationship with the Human Development Index (HDI) and its components in Asia in 2012. This study was an ecological study conducted based on the GLOBOCAN project of the World Health Organization. The correlation between standardized incidence rate (SIR) and standardized mortality rate (SMR) of prostate cancer with HDI and its components was assessed using SPSS Inc Version 18.0 (Chicago). There were 1,094,916 incident cases of prostate cancer and 307,481 deaths recorded in 2012 worldwide. SIR and SMR due to HDI were 72 and 9.7 in very high human development regions, 37.5 and 12.9 in high human development regions, 7 and 3.7 in medium human development regions, and 14.9 and 12.1 in low human development regions per 100,000 people, respectively. A positive correlation of 0.475 was seen between SIR of prostate cancer and HDI (P ≤ 0.001). Also, a negative correlation of 0.160 was seen between SMR of prostate cancer and HDI (P = 0.032). The incidence of prostate cancer is high in countries with higher development. A positive correlation was observed between the SIR of prostate cancer and the HDI and its components, such as life expectancy at birth, mean years of schooling, and the gross national income per capita. In addition, there was a negative correlation between SMR and HDI.

    The aim was to review the worldwide incidence and prevalence of SLE and variation with age, sex, ethnicity and time. A systematic search of MEDLINE and EMBASE search engines was carried out using Medical Subject Headings and keyword search terms for Systemic Lupus Erythematosus combined with incidence, prevalence and epidemiology in August 2013 and updated in September 2016. Author, journal, year of publication, country, region, case-finding method, study period, number of incident or prevalent cases, incidence (per 100 000 person-years) or prevalence (per 100 000 persons) and age, sex or ethnic group-specific incidence or prevalence were collected. The highest estimates of incidence and prevalence of SLE were in North America [23.2/100 000 person-years (95% CI: 23.4, 24.0) and 241/100 000 people (95% CI: 130, 352), respectively]. The lowest incidences of SLE were reported in Africa and Ukraine (0.3/100 000 person-years), and the lowest prevalence was in Northern Australia (0 cases in a sample of 847 people). Women were more frequently affected than men for every age and ethnic group. Incidence peaked in middle adulthood and occurred later for men. People of Black ethnicity had the highest incidence and prevalence of SLE, whereas those with White ethnicity had the lowest incidence and prevalence. There appeared to be an increasing trend of SLE prevalence with time. There are worldwide differences in the incidence and prevalence of SLE that vary with sex, age, ethnicity and time. Further study of genetic and environmental risk factors may explain the reasons for these differences. More epidemiological studies in Africa are warranted.

    The increasing rates of kidney cancer incidence, reported in many populations globally, have been attributed both to increasing exposures to environmental risk factors, as well as increasing levels of incidental diagnosis due to widespread use of imaging. To better understand these trends, we examine long-term cancer registry data worldwide, focusing on the roles of birth cohort and calendar period, proxies for changes in risk factor prevalence and detection practice respectively. We used an augmented version of the Cancer Incidence in Five Continents series to analyze kidney cancer incidence rates 1978-2007 in 16 geographically representative populations worldwide by sex for ages 30-74, using age-period-cohort (APC) analysis. The full APC model provided the best fit to the data in most studied populations. While kidney cancer incidence rates have been increasing in successive generations born from the early twentieth century in most countries, equivalent period-specific rises were observed from the late-1970s, although these have subsequently stabilized in certain European countries (the Czech Republic, Lithuania, Finland, Spain) as well as Japan from the mid-1990s, and from the mid-2000s, in Colombia, Costa Rica and Australia. Our results indicate that the effects of both birth cohort and calendar period contribute to the international kidney cancer incidence trends. While cohort-specific increases may partly reflect the rising trends in obesity prevalence and the need for more effective primary prevention policies, the attenuations in period-specific increases (observed in 8 of the 16 populations) highlight a possible change in imaging practices that could lead to mitigation of overdiagnosis and overtreatment. © 2017 UICC.

    Estimates of the worldwide incidence and mortality from 27 major cancers and for all cancers combined for 2012 are now available in the GLOBOCAN series of the International Agency for Research on Cancer. We review the sources and methods used in compiling the national cancer incidence and mortality estimates, and briefly describe the key results by cancer site and in 20 large "areas" of the world. Overall, there were 14.1 million new cases and 8.2 million deaths in 2012. The most commonly diagnosed cancers were lung (1.82 million), breast (1.67 million), and colorectal (1.36 million); the most common causes of cancer death were lung cancer (1.6 million deaths), liver cancer (745,000 deaths), and stomach cancer (723,000 deaths). © 2014 UICC.

    Type 1 diabetes is the most common form of diabetes in most part of the world, although reliable data are still unavailable in several countries. Wide variations exist between the incidence rates of different populations, incidence is lowest in China and Venezuela (0.1 per 100,000 per year) and highest in Finland and Sardinia (37 per 100,000 per year). In most populations girls and boys are equally affected. In general, the incidence increases with age, the incidence peak is at puberty. After the pubertal years, the incidence rate significantly drops in young women, but remains relatively high in young adult males up to the age 29-35 years. Prospective national and large international registries (DIAMOND and EURODIAB) demonstrated an increasing trend in incidence in most regions of the world over the last few decades and increases seem to be the highest in the youngest age group. Analytical epidemiological studies have identified environmental risk factors operating early in life which might have contributed to the increasing trend in incidence. These include enteroviral infections in pregnant women, older maternal age (39-42 years), preeclampsia, cesarean section delivery, increased birthweight, early introduction of cow's milk proteins and an increased rate of postnatal growth (weight and height). Optimal vitamin D supplementation during early life has been shown to be protective. Some of these environmental risk factors such as viruses may initiate autoimmunity toward the beta cell, other exposures may put on overload on the already affected beta cell and thus accelerate the disease process.

    Breast cancer is the most frequently diagnosed cancer and the leading cause of cancer-related death among women worldwide. Herein, we examine global trends in female breast cancer rates using the most up-to-date data available. Breast cancer incidence and mortality estimates were obtained from GLOBOCAN 2012 (globocan.iarc.fr). We analyzed trends from 1993 onward using incidence data from 39 countries from the International Agency for Research on Cancer and mortality data from 57 countries from the World Health Organization. Of 32 countries with incidence and mortality data, rates in the recent period diverged-with incidence increasing and mortality decreasing-in nine countries mainly in Northern/Western Europe. Both incidence and mortality decreased in France, Israel, Italy, Norway, and Spain. In contrast, incidence and death rates both increased in Colombia, Ecuador, and Japan. Death rates also increased in Brazil, Egypt, Guatemala, Kuwait, Mauritius, Mexico, and Moldova. Breast cancer mortality rates are decreasing in most high-income countries, despite increasing or stable incidence rates. In contrast and of concern are the increasing incidence and mortality rates in a number of countries, particularly those undergoing rapid changes in human development. Wide variations in breast cancer rates and trends reflect differences in patterns of risk factors and access to and availability of early detection and timely treatment. Increased awareness about breast cancer and the benefits of early detection and improved access to treatment must be prioritized to successfully implement breast cancer control programs, particularly in transitioning countries. ©2015 American Association for Cancer Research.

    The Amish have not been previously studied for cancer incidence, yet they have the potential to help in the understanding of its environmental and genetic contributions. The purpose of this study was to estimate the incidence of cancer among the largest Amish population. Adults from randomly selected households were interviewed and a detailed cancer family history was taken. Using both the household interview data and a search of the Ohio cancer registry data, a total of 191 cancer cases were identified between the years 1996 and 2003. The age-adjusted cancer incidence rate for all cancers among the Amish adults was 60% of the age-adjusted adult rate in Ohio (389.5/10(5) vs. 646.9/10(5); p Amish was 37% of the rate for Ohio adults (p Amish was 72% of the age-adjusted adult rate in Ohio (p = 0.0001). Cancer incidence is low in the Ohio Amish. These data strongly support reduction of cancer incidence by tobacco abstinence but cannot be explained solely on this basis. Understanding these contributions may help to identify additional important factors to target to reduce cancer among the non-Amish.

    Gastric cancer is the fourth most common malignancy worldwide. The incidence trends and mortality rates of gastric cancer in Israel have not been studied in depth. The aim of our study was to try and investigate the aforementioned issues in Israel in different ethnic groups. This retrospective study is based on the data of The Israel National Cancer Registry and The Central Bureau of Statistics. Published data from these two institutes were collected, summarized, and analyzed in this study. Around 650 new cases of gastric cancer are diagnosed yearly in Israel. While we noticed a decline during the period 1990-2007 in the incidence in the Jewish population (13.6-8.9 and 6.75-5.42 cases per 100,000 in Jewish men and women, respectively), an increase in the Arab population was noticed (7.7-10.2 and 3.7-4.2 cases per 100,000 in men and women, respectively). Age-adjusted mortality rates per 10,000 cases of gastric cancer decreased significantly, from 7.21 in 1990 to 5.46 in 2007, in the total population. The 5-year relative survival showed a slight increase for both men and women. There is a difference in the incidence and outcome of gastric cancer between the Jewish and Arab populations in Israel. The grim prognosis of gastric cancer patients in Israel is probably due to the advanced stage at which gastric cancer is diagnosed in Israel.

    To date, the burden of cancer among young adults has rarely been studied in depth. Our aim was to describe the scale and profile of cancer incidence and mortality worldwide among 20-39 year-olds, highlighting major patterns by age, sex, development level, and geographical region. We did a population-based study to quantify the burden of young adult cancers worldwide. We defined young adult cancers as those occurring between the ages of 20 and 39 years because these individuals will have passed puberty and adolescence, but not yet experienced the effects of hormonal decline, immune response deterioration, or organ dysfunction associated with chronic health conditions. Global, regional, and country-specific (n=184) data estimates of the number of new cancer cases and cancer-associated deaths that occurred in 2012 among young adults were extracted in four 5-year bands from the International Agency for Research on Cancer's GLOBOCAN 2012 for all cancers combined and for 27 major types as defined by the International Classification of Disease, tenth revision. We report the number of new cancer cases and cancer-associated deaths overall and by sex alongside corresponding age-standardised rates (ASR) per 100 000 people per year. We also present results using four levels of the Human Development Index (HDI; low [least developed], medium, high, and very high [most developed]), which is a composite indicator for socioeconomic development comprising life expectancy, education, and gross national income. 975 396 new cancer cases and 358 392 cancer-associated deaths occurred among young adults worldwide in 2012, which equated to an ASR of 43·3 new cancer cases per 100 000 people per year and 15·9 cancer-associated deaths per 100 000 people per year. The burden was disproportionally greater among women and the most common cancer types overall in terms of new cases were female breast cancer, cervical cancer, thyroid cancer, leukaemia, and colorectal cancer; in terms of

    Anterior cruciate ligament (ACL) reconstructions are among the most common sports medicine procedures performed in the US each year. Differences have been reported in the incidence rates (IRs) of ACL tears among male and female national elite athletes. However, there is little information in the published literature that assesses IRs for ACL reconstructions done in the Health Maintenance Organization (HMO) setting specifically. Different populations may show variation in ACL reconstruction IRs. This study reports on the IR of ACL reconstructions in a predefined population and compares the differences in age and sex over time. A retrospective analysis of 4485 ACL reconstructions performed within Kaiser Permanente Southern California between 2001 and 2005 was completed by a query of an administrative database. Trends in IRs per 100,000 members were calculated and compared across age, sex, and the five-year study period. Linear regression was used to test trends in IR. Sex distribution was compared using the χ(2) test. Analysis of variance was used to compare the mean age from year to year in males and females. The independent sample t-test was used to compare mean age between males and females for each independent year. The IR of ACL reconstructions in females rose significantly (p = 0.010) from 14.4 in 2001 (95% confidence interval [CI], 12.6-16.3) to 19.3 in 2005 (95% CI, 17.2-21.5). Within specific age groups, IR increased significantly for females age 14 to 17 (p = 0.013), 18 to 21 (p = 0.017), and 45 to 49 years (p = 0.014). The most dramatic change was seen in the female age category of 14 to 17 years, which increased at a rate of 8.14 cases/100,000 members per year. Identifying the sex and age groups with most rapidly increasing rates of ACL reconstructions is important in implementing ACL injury-prevention programs.

    The primary objective of this observational study was to document the heart rate (HR) responses of firefighters during incident rehabilitation following firefighting activity in a high-rise building with a simulated fire on the 10th floor. Additionally, the study investigated potential factors, including firefighting workload, ambient temperature, firefighter movement, and individual characteristics, that may have affected HR during recovery. Firefighters (n = 198) were assigned to perform a simulation of fire suppression, search and rescue, or material support during one of six firefighting trials that involved different crew sizes and ascent modes, and were performed in different environmental conditions. After completing the simulated firefighting activity, firefighters reported to a rehabilitation area on the 8th floor. The rehabilitation area was staffed by firefighter/paramedics. HR was monitored continuously during simulated firefighting activity and a 15-minute rehabilitation period. Average HR during rehabilitation (HRmean) was calculated and compared across trials. Simulated firefighting activity was performed in the summer in Virginia, USA, and ambient conditions varied among trials (mean ± SD: 31 ± 4°C; 46 ± 15% relative humidity; 32 ± 4°C heat index). Duration of simulated firefighting activity ranged from 12.0 to 20.3 minutes among trials (mean: 15.4 ± 5.2 minutes). Over all trials, mean peak HR during simulations was 173 ± 18 beats·min(-1). Mean HR over all trials at entry into rehabilitation was 149 ± 24 beats·min(-1). Following 15 minutes of recovery, mean HR over all trials was 126 ± 23 beats·min(-1). Exploratory analyses revealed that higher workload during firefighting (stair trials), higher ambient temperature (≥30°C), greater movement during rehabilitation (≥0.1 g-force), higher age (≥45 years), and higher BMI (≥30.0 kg·m(-2)) were associated with higher HR responses during rehabilitation.

    To systematically review recidivism rates internationally, report whether they are comparable and, on the basis of this, develop best reporting guidelines for recidivism. We searched MEDLINE, Google Web, and Google Scholar search engines for recidivism rates around the world, using both non-country-specific searches as well as targeted searches for the 20 countries with the largest total prison populations worldwide. We identified recidivism data for 18 countries. Of the 20 countries with the largest prison populations, only 2 reported repeat offending rates. The most commonly reported outcome was 2-year reconviction rates in prisoners. Sample selection and definitions of recidivism varied widely, and few countries were comparable. Recidivism data are currently not valid for international comparisons. Justice Departments should consider using the reporting guidelines developed in this paper to report their data.

    Full Text Available Background/Aims. Inflammatory bowel disease (IBD is associated with an increased risk of colorectal cancer (CRC. In addition, there may be an association between leukemia and lymphoma and IBD. We conducted a systematic review and meta-analysis of the IBD literature to estimate the incidence of CRC, leukemia, and lymphoma in adult IBD patients. Methods. Studies were identified by a literature search of PubMed, Cochrane Library, Medline, Web of Science, Scopus, EMBASE, and ProQuest Dissertations and Theses. Pooled incidence rates (per 100,000 person-years [py] were calculated through use of a random effects model, unless substantial heterogeneity prevented pooling of estimates. Several stratified analyses and metaregression were performed to explore potential study heterogeneity and bias. Results. Thirty-six articles fulfilled the inclusion criteria. For CRC, the pooled incidence rate in CD was 53.3/100,000 py (95% CI 46.3–60.3/100,000. The incidence of leukemia was 1.5/100,000 py (95% CI −0.06–3.0/100,000 in IBD, 0.3/100,000 py (95% CI −1.0–1.6/100,000 in CD, and 13.0/100,000 py (95% CI 5.8–20.3/100,000 in UC. For lymphoma, the pooled incidence rate in CD was 0.8/100,000 py (95% CI −0.4–2.1/100,000. Substantial heterogeneity prevented the pooling of other incidence estimates. Conclusion. The incidence of CRC, leukemia, and lymphoma in IBD is low.

    2012-09-01

    This report presents a preliminary survey and analysis of the five primary types of commercial nuclear power reactors currently in use around the world. Plutonium mass discharge rates from the reactors’ spent fuel at reload are estimated based on a simple methodology that is able to use limited reactor burnup and operational characteristics collected from a variety of public domain sources. Selected commercial reactor operating and nuclear core characteristics are also given for each reactor type. In addition to the worldwide commercial reactors survey, a materials test reactor survey was conducted to identify reactors of this type with a significant core power rating. Over 100 material or research reactors with a core power rating >1 MW fall into this category. Fuel characteristics and spent fuel inventories for these material test reactors are also provided herein.

    Sepsis, the most severe manifestation of acute infection, poses a major challenge to health care systems around the world. To date, adequate data on the incidence and mortality of sepsis in Germany have been lacking. Nationwide case-related hospital DRG statistics for the years 2007-2013 were used to determine the in-hospital incidence and mortality of sepsis. Cases were identified on the basis of the clinical and pathogen-based ICD-10 codes for sepsis. The statistical evaluation was standardized for age and sex and carried out separately for each age group. The number of cases of sepsis rose by an average of 5.7% per year, from 200 535 in 2007 to 279 530 in 2013, corresponding to an increase in the adjusted in-hospital incidence from 256 to 335 cases per 100 000 persons per year. The percentage of patients with severe sepsis rose from 27% to 41%. The in-hospital mortality of sepsis fell over the same period by 2.7%, to 24.3%. In 2013, 67 849 persons died of sepsis in German hospitals (or died of another disease, but also had sepsis). The incidence was highest in the youngest and oldest age groups, and the in-hospital mortality rose nearly linearly with age from age 40 onward. Sepsis and death from sepsis are markedly more common in Germany than previously assumed, and they are on the rise. Sepsis statistics should become a standard component of federal statistical reports on public health, as well as of hospital statistics. Preventive measures and evidencebased treatment should be implemented across the nation.

    Incidence rates are fundamental to epidemiology, but their magnitude and interpretation depend on methodological choices. We aimed to examine the extent to which the definition of the study population affects cancer incidence rates. All primary cancer diagnoses in Sweden between 1958 and 2010 were identified from the national Cancer Register. Age-standardized and age-specific incidence rates of 29 cancer subtypes between 2000 and 2010 were calculated using four definitions of the study population: persons resident in Sweden 1) based on general population statistics; 2) with no previous subtype-specific cancer diagnosis; 3) with no previous cancer diagnosis except non-melanoma skin cancer; and 4) with no previous cancer diagnosis of any type. We calculated absolute and relative differences between methods. Age-standardized incidence rates calculated using general population statistics ranged from 6% lower (prostate cancer, incidence rate difference: -13.5/100,000 person-years) to 8% higher (breast cancer in women, incidence rate difference: 10.5/100,000 person-years) than incidence rates based on individuals with no previous subtype-specific cancer diagnosis. Age-standardized incidence rates in persons with no previous cancer of any type were up to 10% lower (bladder cancer in women) than rates in those with no previous subtype-specific cancer diagnosis; however, absolute differences were cancer subtypes. For some cancer subtypes incidence rates vary depending on the definition of the study population. For these subtypes, standardized incidence ratios calculated using general population statistics could be misleading. Moreover, etiological arguments should be used to inform methodological choices during study design.

    Widespread use of artificial light at night (ALAN) might contribute to the global burden of hormone-dependent cancers. Previous attempts to verify this association in population-level studies have been sparse. Using GLOBOCAN, US-DMSP, and World Bank 2010-2012 databases, we studied the association between ALAN and prostate cancer (PC) incidence in 180 countries worldwide, controlling for several country-level confounders. The PC-ALAN association emerged marginally significant when year-2012 PC age-standardized rate data were compared with ALAN levels (t = 1.886, p 2.7; p < .01) when only 110 countries with well-maintained cancer registries were analyzed. Along with other variables, ALAN explains up to 79% of PC ASR variability. PC-ALAN association appears to vary regionally, with the greatest deviations in Central Africa, Small Island Developing States, Southeast Asia, and Gulf States.

    Lymphoma is the third most common pediatric malignancy. The purpose of this study was to analyze the incidence rates of lymphoma in children and adolescents in Brazil. All cases of Hodgkin lymphoma (HL), non-Hodgkin lymphoma (NHL), and Burkitt lymphoma (BL) were extracted from 14 population-based cancer registries (PBCRs) from 2000 to 2005, and included children and adolescents 0-19 years old. Analyses included age-adjusted incidence rates (AAIRs) and age-specific incidence rates (ASIRs) by each PBCR. A social exclusion index (SEI) was built and used as proxy for socioeconomic status (SES) levels. Correlations between SES and incidence rates were investigated using Spearman's test. The median incidence of lymphoma was 22.7/million. AAIRs of lymphomas varied from 12.9 (Salvador) to 34.5 per million (São Paulo). Median AAIR was 8.8/million, 9.8/million, and 2.9/million for NHL, HL, and BL, respectively. In all PBCRs except that of Recife, AAIR was slightly higher in males than females. The median ASIR was highest for HL (18.5/million) at 15-19 years for both genders. For NHL there were two peaks for ASIR: 11.1/million (1-4 years of age) and 13.2/million (15-19 years of age). The median ASIR for BL was highest among children aged 1-4 years (4.7/million) and in males. Higher SEI correlated with higher incidence of HL (P = 0.06), whereas rates of NHL and BL did not correlate with SEI. Borderline different incidence rates were observed in HL correlated with cities with higher SEIs. Incidence rates of lymphomas in Brazil do not differ compared to rates reported worldwide, although SES differences deserve further investigation. Copyright © 2012 Elsevier Ltd. All rights reserved.

    The aim of the current analysis is to analyze suicide rates in adolescents aged 15-19 years in decades between 1990 and 2009 worldwide. Suicide data were obtained from the World Health Organization Mortality Database and population data from the World Bank Data set. In total, 81 countries or territories, having data at least for 5 years in 1990-1999 and in 2000-2009, were included in the analysis. Additional analysis for regional trends with 57 countries was performed. Over the decades considered, analysis showed a declining trend in the overall suicide rate for males from 10.30 to 9.51 per 100,000 (p = .076), and for females from 4.39 to 4.18 (p = .472). The average suicide rate showed a significant decline for both genders in Europe, dropping from 13.13 to 10.93 (p = .001) in males and from 3.88 to 3.34 in females (p = .038). There was a significant increase in South American countries for males, from 7.36 to 11.47 (p = .016), and a close to significant rise for females, from 5.59 to 7.98 (p = .053). Although other world regions did not show significant trends, there were several significant changes at country level. Reasons behind the decrease in Western countries could potentially be related to the overall improvements in global health; the possible contribution of suicide prevention activities remains unclear. Increases in several South American countries might be related to economic recession and its impact on adolescents from diverse cultural backgrounds, and partly also to improvements in mortality registration.

    Dana S Mowls

    Full Text Available Lung cancer is the second most frequently diagnosed cancer among men and women in the United States. With cigarette smoking causing the majority of cases, patterns in lung cancer are often monitored to understand the impact of anti-tobacco efforts. The purpose of this research was to investigate trends in lung cancer incidence rates for the period 2005-2010 in Oklahoma.Data on Oklahoma's incident cases of lung cancer (2005-2010 were obtained from the Centers for Disease Control and Prevention WONDER system. Annual percent change (APC was calculated by linear regression to characterize trends in lung cancer incidence rates over time for the overall population, by gender, by age group, and by age group within gender. Rates were considered to increase or decrease if the p-value for trend was <0.05.From 2005 through 2010, lung cancer incidence rates declined from 81.96 to 68.19 per 100,000 population, with an APC of -3.58% (p-value: 0.0220. When subgroups were examined, declines were observed among all males (APC: -4.25%; p-value: 0.0270, males <65 years (APC: -5.32%; p-value: 0.0008, females <65 years (APC: -4.85%; p-value: 0.0044, and persons aged 55-64 years (APC: -6.38%; p-value: 0.0017.Declines in lung cancer incidence rates occurred during 2005-2010 among the overall population and within select demographic groups in Oklahoma. Although trends were stable for several demographic groups, rates of lung cancer incidence were lower in 2010 compared to 2005. Continued evidence-based tobacco control efforts are needed to ensure further reductions in lung cancer incidence rates in the state of Oklahoma.

    2016-01-01

    OBJECTIVES This is the first study that estimates the incidence and mortality rate for colorectal cancer (CRC) patients in Malaysia by sex and ethnicity. METHODS The 4,501 patients were selected from National Cancer Patient Registry-Colorectal Cancer data. Patient survival status was cross-checked with the National Registration Department. The age-standardised rate (ASR) was calculated as the proportion of CRC cases (incidence) and deaths (mortality) from 2008 to 2013, weighted by the age structure of the population, as determined by the Department of Statistics Malaysia and the World Health Organization world standard population distribution. RESULTS The overall incidence rate for CRC was 21.32 cases per 100,000. Those of Chinese ethnicity had the highest CRC incidence (27.35), followed by the Malay (18.95), and Indian (17.55) ethnicities. The ASR incidence rate of CRC was 1.33 times higher among males than females (24.16 and 18.14 per 100,000, respectively). The 2011 (44.7%) CRC deaths were recorded. The overall ASR of mortality was 9.79 cases, with 11.85 among the Chinese, followed by 9.56 among the Malays and 7.08 among the Indians. The ASR of mortality was 1.42 times higher among males (11.46) than females (8.05). CONCLUSIONS CRC incidence and mortality is higher in males than females. Individuals of Chinese ethnicity have the highest incidence of CRC, followed by the Malay and Indian ethnicities. The same trends were observed for the age-standardised mortality rate. PMID:26971697

    Cholesteatoma patients have a high risk of recurrence with complications, and knowledge exchange is a prerequisite for improving treatment. This study aimed to apply appropriate statistics to provide meaningful and transferable results from cholesteatoma surgery, to highlight independent prognostic factors, and to assess the incidence rate. Incidence rates were assessed for the district of Aarhus, Denmark. From 147 patients operated on mainly with canal wall up mastoidectomies for debuting cholesteatomas, 10-year Kaplan-Meier recidivism rates were calculated and independent prognostic factors for the recidivism were identified by Cox multivariate regression analyses. Incidence rate was 6.8 per 100 000 per year. The 10-year cumulative recidivism rate was 0.44 (95 per cent confidence interval, 0.37-0.53). Independent prognostic factors for the recidivism were: age below 15 years (hazard ratio = 2.2; p > z = 0.002), cholesteatoma localised to the mastoid (hazard ratio = 1.7; p > z = 0.04), stapes erosion (hazard ratio = 1.9; p > z = 0.02) and incus erosion (hazard ratio = 1.9; p > z = 0.04). The recidivism rate is influenced by several factors that are important to observe, both in the clinic and when comparing results from surgery.

    To determine the incidence rate and distribution of anemia types over time from an Inflammatory Bowel Disease (IBD) patient cohort spanning 18 years. Between January 1995 and November 2013, the University Hospital digital databases as well as hard copies of patients' files were reviewed retrospectively. IBD patients with at least one complete blood count (CBC) report were included in this study. We obtained 941 IBD patients' records; 375 (39.9%) patients were diagnosed with Crohn's disease (CD), and 566 (60.1%) patients had ulcerative colitis (UC). Anemia was detected in 548 (58.2%) patients. Female patients were more frequently anemic than male patients (68.4% vs. 49.7%, p=0.001). The frequency of anemia was slightly higher in patients with CD (62.1%) than in patients with UC (55.7%) (p=0.04). The incidence rate of anemia for the entire IBD patient cohort was calculated as 103.45 per 1,000 patient-years. The correlation between the age of the IBD disease and the presence of anemia exhibited a high correlation coefficient of Pearson's r=0.702. This is the first study to report the incidence rate of anemia (103.45 per 1,000 patient-years) in a long-term cohort of IBD patients.

  7. p53 mutations associated with aging-related rise in cancer incidence rates

    Richardson, Richard B

    2013-01-01

    TP53’s role as guardian of the genome diminishes with age, as the probability of mutation increases. Previous studies have shown an association between p53 gene mutations and cancer. However, the role of somatic TP53 mutations in the steep rise in cancer rates with aging has not been investigated at a population level. This relationship was quantified using the International Agency for Research on Cancer (IARC) TP53 and GLOBOCAN cancer databases. The power function exponent of the cancer rate was calculated for 5-y age-standardized incidence or mortality rates for up to 25 cancer sites occurring in adults of median age 42 to 72 y. Linear regression analysis of the mean percentage of a cancer’s TP53 mutations and the corresponding cancer exponent was conducted for four populations: worldwide, Japan, Western Europe, and the United States. Significant associations (P ≤ 0.05) were found for incidence rates but not mortality rates. Regardless of the population studied, positive associations were found for all cancer sites, with more significant associations for solid tumors, excluding the outlier prostate cancer or sex-related tumors. Worldwide and Japanese populations yielded P values as low as 0.002 and 0.005, respectively. For the United States, a significant association was apparent only when analysis utilized the Surveillance, Epidemiology, and End Results (SEER) database. This study found that TP53 mutations accounts for approximately one-quarter and one-third of the aging-related rise in the worldwide and Japanese incidence of all cancers, respectively. These significant associations between TP53 mutations and the rapid rise in cancer incidence with aging, considered with previously published literature, support a causal role for TP53 according to the Bradford-Hill criteria. However, questions remain concerning the contribution of TP53 mutations to neoplastic development and the role of factors such as genetic instability, obesity, and gene deficiencies

Using a large national database, we examined changes in age-adjusted incidence (AAIR), mortality rates (MR) and 5-year cancer-specific survival (CSS) for 378 patients diagnosed with NEPC between 1992 and 2011. Analysis was performed for all NEPC and for its two major sub-groups [small cell carcinoma (SCC) and neuroendocrine carcinoma (NEC)]. AAIR of NEPC continues to rise in recent years (2004-2011:+6.8%/year, p>0.05). AAIR of SCC has been increasing significantly by 6.94%/year since 2001 (from 0.470 to 0.582/1,000,000 person years, pAAIR of SCC is increasing with no change in the MR of NEPC over the past 20 years.

    Tuberculosis (TB) continues to be a considerable burden especially for millions of young adults and disadvantaged people worldwide. The TB incidence and notification rates are good indicators of TB situation in a country. Our aim was to compare TB incidence and notification rates in Kosovo and in seven other Balkan countries. Retrospective epidemiologic analysis of published data on TB incidence and notification rates in eight Balkan countries in 2012. Notification rates were expressed per 100,000 inhabitants and were calculated based on the number of TB cases reported divided by the population of each country under analysis. The TB incidence in Kosovo (47/100,000) was considerably higher compared to its four neighboring countries: Albania (16/100,000), Macedonia, Montenegro (18/100,000) and Serbia (23/100,000). The TB notification rates in Kosovo and other countries closely mimicked the incidence rates in these countries. The exceptionally high TB incidence rate in Kosovo could be due to many factors including low health and medical-seeking behaviors of the local population, poverty and low education levels. Effective interventions should be adapted to the local context in order to increase the chances of success.

    Hip fractures represent a major public health challenge worldwide. Multinational studies using a common methodology are scarce. We aimed to estimate the incidence rates (IRs) and trends of hip/femur fractures over the period 2003-2009 in five European countries. The study was performed using seven...... electronic health-care records databases (DBs) from Denmark, The Netherlands, Germany, Spain, and the United Kingdom, based on the same protocol. Yearly IRs of hip/femur fractures were calculated for the general population and for those aged ≥50 years. Trends over time were evaluated using linear regression......, P fractures varied greatly across European countries. With the exception of Denmark, no decreasing trend was observed over the study period....

    Oral cancer is a significant public health problem world-wide and exerts high economic, social, psychological, and physical burdens on patients, their families, and on their primary care providers. We set out to describe the changing trends in incidence and survival rates of oral cancer in Ireland between 1994 and 2009. National data on incident oral cancers [ICD 10 codes C01-C06] were obtained from the National Cancer Registry Ireland from 1994 to 2009. We estimated annual percentage change (APC) in oral cancer incidence during 1994-2009 using joinpoint regression software (version 4.2.0.2). The lifetime risk of oral cancer to age 79 was estimated using Irish incidence and population data from 2007 to 2009. Survival rates were also examined using Kaplan-Meier curves and Cox proportional hazard models to explore the influence of several demographic/lifestyle covariates with follow-up to end 2012. Data were obtained on 2,147 oral cancer incident cases. Men accounted for two-thirds of oral cancer cases (n = 1,430). Annual rates in men decreased significantly during 1994-2001 (APC = -4.8 %, 95 % CI: -8.7 to -0.7) and then increased moderately (APC = 2.3 %, 95 % CI: -0.9 to 5.6). In contrast, annual incidence increased significantly in women throughout the study period (APC = 3.2 %, 95 % CI: 1.9 to 4.6). There was an elevated risk of death among oral cancer patients who were: older than 60 years of age; smokers; unemployed or retired; those living in the most deprived areas; and those whose tumour was sited in the base of the tongue. Being married and diagnosed in more recent years were associated with reduced risk of death. Oral cancer increased significantly in both sexes between 1999 and 2009 in Ireland. Our analyses demonstrate the influence of measured factors such as smoking, time of diagnosis and age on observed trends. Unmeasured factors such as alcohol use, HPV and dietary factors may also be contributing to increased trends. Several of

    Stillbirths do not count in routine worldwide data-collating systems or for the Millennium Development Goals. Two sets of national stillbirth estimates for 2000 produced similar worldwide totals of 3·2 million and 3·3 million, but rates differed substantially for some countries. We aimed to develop more reliable estimates and a time series from 1995 for 193 countries, by increasing input data, using recent data, and applying improved modelling approaches. For international comparison, stillbirth is defined as fetal death in the third trimester (≥1000 g birthweight or ≥28 completed weeks of gestation). Several sources of stillbirth data were identified and assessed against prespecified inclusion criteria: vital registration data; nationally representative surveys; and published studies identified through systematic literature searches, unpublished studies, and national data identified through a WHO country consultation process. For 2009, reported rates were used for 33 countries and model-based estimates for 160 countries. A regression model of log stillbirth rate was developed and used to predict national stillbirth rates from 1995 to 2009. Uncertainty ranges were obtained with a bootstrap approach. The final model included log(neonatal mortality rate) (cubic spline), log(low birthweight rate) (cubic spline), log(gross national income purchasing power parity) (cubic spline), region, type of data source, and definition of stillbirth. Vital registration data from 79 countries, 69 nationally representative surveys from 39 countries, and 113 studies from 42 countries met inclusion criteria. The estimated number of global stillbirths was 2·64 million (uncertainty range 2·14 million to 3·82 million) in 2009 compared with 3·03 million (uncertainty range 2·37 million to 4·19 million) in 1995. Worldwide stillbirth rate has declined by 14·5%, from 22·1 stillbirths per 1000 births in 1995 to 18·9 stillbirths per 1000 births in 2009. In 2009, 76·2% of

    To systematically review the literature investigating the incidence of fatal and or nonfatal low-speed vehicle run-over (LSVRO) incidents in children aged 0-15 years. The following databases were searched using specific search terms, from their date of conception up to June 2011: Cochrane Library, Medline, CINAHL, Embase, AMI, Sociological Abstracts, ERIC, PsycArticles, PsycInfo, Urban Studies and Planning; Australian Criminology Database; Dissertations and Thesis; Academic Research Library; Social Services Abstracts; Family and Society; Scopus; and Web of Science. A total of 128 articles were identified in the databases (33 found by hand searching). The title and abstract of these were read, and 102 were removed because they were not primary research articles relating to LSVRO-type injuries. Twenty-six articles were assessed against the inclusion (reporting population level incidence rates) and exclusion criteria, 19 of which were excluded, leaving a total of five articles for inclusion in the review. Five studies were identified that met the inclusion criteria. The incidence rate in nonfatal LSVRO events varied in the range of 7.09 to 14.79 per 100,000 and from 0.63 to 3.2 per 100,000 in fatal events. Using International Classification of Diseases codes for classifying fatal or nonfatal LSVRO incidents is problematic as there is no specific code for LSVRO. The current body of research is void of a comprehensive secular population data analysis. Only with an improved spectrum of incidence rates will appropriate evaluation of this problem be possible, and this will inform nursing prevention interventions. The effect of LSVRO incidents is clearly understudied. More research is required to address incidence rates in relation to culture, environment, risk factors, car design, and injury characteristics. The lack of nursing research or policy around this area of injury, most often to children, indicates a field of inquiry and policy development that needs attention.

    Background Diarrheal diseases remain a major cause of mortality in Africa and worldwide. While the burden of rotavirus is well described, population-based rates of disease caused by norovirus, sapovirus, and astrovirus are lacking, particularly in developing countries. Methods Data on diarrhea cases were collected through a population-based surveillance platform including healthcare encounters and household visits in Kenya. We analyzed data from June 2007 to October 2008 in Lwak, a rural site in western Kenya, and from October 2006 to February 2009 in Kibera, an urban slum. Stool specimens from diarrhea cases of all ages who visited study clinics were tested for norovirus, sapovirus, and astrovirus by RT-PCR. Results Of 334 stool specimens from Lwak and 524 from Kibera, 85 (25%) and 159 (30%) were positive for norovirus, 13 (4%) and 31 (6%) for sapovirus, and 28 (8%) and 18 (3%) for astrovirus, respectively. Among norovirus-positive specimens, genogroup II predominated in both sites, detected in 74 (87%) in Lwak and 140 (88%) in Kibera. The adjusted community incidence per 100,000 person-years was the highest for norovirus (Lwak: 9,635; Kibera: 4,116), followed by astrovirus (Lwak: 3,051; Kibera: 440) and sapovirus (Lwak: 1,445; Kibera: 879). For all viruses, the adjusted incidence was higher among children aged <5 years (norovirus: 22,225 in Lwak and 17,511 in Kibera; sapovirus: 5,556 in Lwak and 4,378 in Kibera; astrovirus: 11,113 in Lwak and 2,814 in Kibera) compared to cases aged ≥5 years. Conclusion Although limited by a lack of controls, this is the first study to estimate the outpatient and community incidence rates of norovirus, sapovirus, and astrovirus across the age spectrum in Kenya, suggesting a substantial disease burden imposed by these viruses. By applying adjusted rates, we estimate approximately 2.8–3.3 million, 0.45–0.54 million, and 0.77–0.95 million people become ill with norovirus, sapovirus, and astrovirus, respectively, every year in

    Several studies have shown that the prevalence of the frequent chronic conditions of atopic dermatitis, asthma, and allergy has increased substantially for reasons not fully understood. Atopic diseases affect quality of life in both children and their family members. Using national registers, we sought to establish up-to-date incidence rates of atopic dermatitis, asthma, and allergic rhinoconjunctivitis in the Danish and Swedish child populations. Children born in Denmark from 1997 to 2011 or born in Sweden from 2006 to 2010 participated in this cross-national, population-based cohort study. Incidence rates of atopic dermatitis, asthma, and allergic rhinoconjunctivitis in the Danish and Swedish child cohorts were ascertained through disease-specific dispensed prescribed medication, specific hospital contacts, or both. In both countries the incidence rate of atopic dermatitis was stable during the study periods. The incidence rate of asthma increased until 2006 and stabilized for the rest of the study period in Denmark and increased in Sweden. The incidence rate of allergic rhinoconjunctivitis decreased in both countries. The study revealed similar trends, with stable incidence rates of atopic dermatitis in both Danish and Swedish children, an increase and then stabilization in asthma incidence rates in Denmark and an increase in Sweden, and a decrease in allergic rhinoconjunctivitis incidence rates. At age 5 years, one third of all children were affected with at least one of the conditions of atopic dermatitis, asthma, or allergic rhinoconjunctivitis.

    Antimicrobial drug resistance can hinder gonorrhea prevention and control efforts. In this study, we analyzed historical ciprofloxacin resistance data and gonorrhea incidence data to examine the possible effect of antimicrobial drug resistance on gonorrhea incidence at the population level. We analyzed data from the Gonococcal Isolate Surveillance Project and city-level gonorrhea incidence rates from surveillance data for 17 cities during 1991–2006. We found a strong positive association between ciprofloxacin resistance and gonorrhea incidence rates at the city level during this period. Their association was consistent with predictions of mathematical models in which resistance to treatment can increase gonorrhea incidence rates through factors such as increased duration of infection. These findings highlight the possibility of future increases in gonorrhea incidence caused by emerging cephalosporin resistance. PMID:24655615

    Full Text Available Bacground/Aim. Radical hysterectomy is a surgical approach for stage Ib and IIa of cervical cancer. The incidence of intraoperative injuries of the bladder during radical hysterectomy ranges from 0.4-3.7%. The ureter can be crushed, caught in sutures, transsected, obstructed by angulation, or ischemic by the stippling or periureteric fascia. Vesicovaginal and ureterovaginal fistuls are reported to develop in 0.9-2% of patients after radical abdominal hysterectomy. Fistulas usually become manifested or visible at speculum examination within 14 days following the surgery. The aim of this study was to establish the incidence and predisposing factor of urological complications after radical hysterectomy. Methods. The study included a total of 536 patients with invasive stage Ib to IIb cancer of the cervix uteri who had underwent radical hysterectomy. The special elements considered were: the patient’s age; the International Federation of Ginecology and Obstetrics (FIGO stage after pathohistology; duration of operation; the result of preoperative laboratory tests for diabetes, anemia, hypoproteinemia, or disorders of liver or kidney function; ASA status; postoperative surgical infection. Results. The average age of the patients with complications was 48.68 years. All patients with intraoperative ureteric and bladder injuries had statisticaly significant higher stage of disease and operation lasted more than in others without injury. We noticed 1.3% ureteral injuries and 1.49% bladder injuries, more than 50% of the patients with a previously mentioned injuries were operated on more than 3 hours. We found 2.61% vesicovaginal and 2.43% ureterovaginal fistuls. A total of 50% of the patients with bladder injury and vesicovaginal fistuls and 70% of the patients with ureterovaginal fistuls had diabetes mellitus. Postoperative infection of surgical site is a very important factor for the development of fistule. Half of the patients with vesicovaginal

    Quantify, for both genders, the correlation between the depression incidence rate and the unemployment rate in Portugal between 1995 and 2013. An ecological study was developed to correlate the evolution of the depression incidence rates estimated by the General Practitioner Sentinel Network and the annual unemployment rates provided by the National Statistical Institute in official publications. There was a positive correlation between the depression incidence rate and the unemployment rate in Portugal, which was significant only for males (R2 = 0.83, p = 0.04). For this gender, an increase of 37 new cases of depression per 100,000 inhabitants was estimated for each 1% increase in the unemployment rate between 1995 and 2013. Although the study design does not allow the establishment of a causal association between unemployment and depression, the results suggest that the evolution of unemployment in Portugal may have had a significant impact on the level of mental health of the Portuguese, especially among men.

    Full Text Available Abstract Background Recent declines in invasive breast cancer have been reported in the US, with many studies linking these declines to reductions in the use of combination estrogen/progestin hormone therapy (EPHT. We evaluated the changing use of postmenopausal hormone therapy, mammography screening rates, and the decline in breast cancer incidence specifically for Marin County, California, a population with historically elevated breast cancer incidence rates. Methods The Marin Women's Study (MWS is a community-based, prospective cohort study launched in 2006 to monitor changes in breast cancer, breast density, and personal and biologic risk factors among women living in Marin County. The MWS enrolled 1,833 women following routine screening mammography between October 2006 and July 2007. Participants completed a self-administered questionnaire that included items regarding historical hormone therapy regimen (estrogen only, progesterone only, EPHT, age of first and last use, total years of use, and reason(s for stopping, as well as information regarding complementary hormone use. Questionnaire items were analyzed for 1,083 non-Hispanic white participants ages 50 and over. Breast cancer incidence rates were assessed overall and by tumor histology and estrogen receptor (ER status for the years 1990-2007 using data from the Northern California Surveillance, Epidemiology and End Results (SEER cancer registry. Results Prevalence of EPHT use among non-Hispanic white women ages 50 and over declined sharply from 21.2% in 1998 to 6.7% by 2006-07. Estrogen only use declined from 26.9% in 1998 to 22.4% by 2006-07. Invasive breast cancer incidence rates declined 33.4% between 2001 and 2004, with drops most pronounced for ER+ cancers. These rate reductions corresponded to declines of about 50 cases per year, consistent with population attributable fraction estimates for EPHT-related breast cancer. Self-reported screening mammography rates did not change

    Marked unexplained national variations in incidence rates of kidney cancer have been observed for decades in Europe. To investigate geographic variations at the regional level and identify European regions with high incidence rates of kidney cancer. Regional- and national-level incidence data were extracted from the Cancer Incidence in Five Continents databases, local cancer registry databases, and local published reports. World population age-standardised rates (ASRs) were calculated for the periods 2003-2007 and 1988-1992. Rates by period and sex were compared using map visualisation. During 2003-2007, the highest ASR was found in the Plzen region, Czech Republic (31.4/100,000 person-years in men). Other regions of the Czech Republic had ASRs of 18.6-27.5/100,000 in men, with a tendency for higher rates in regions south of Prague. Surrounding regions, including eastern Germany and regions of Slovakia and Austria, had medium-to-high incidence rates (13.0-16.8/100,000 in men). Three other areas in Europe showed higher incidence rates in men compared with the rest of the continent: Lithuania, Estonia, Latvia, and Belarus (15.0-17.6/100,000); Iceland (13.5/100,000), and northern Italy (up to 16.0/100,000). Similar regional differences were observed among women, with rates approximately half of those observed in men in the same region. In general, these regional geographic variations remained stable over the periods 1988-1992 and 2003-2007, although higher incidence rates were detected in the Baltic countries in 2003-2007. Several European regions show particularly high rates of kidney cancer incidence. Large variations were observed within countries covered by national health-care systems, implying that overdetection is not the major factor. We present regional geographic variations in kidney cancer incidence rates in Europe. We highlight several regions with high incidence rates where further studies should be conducted for cancer control and prevention. Copyright

    The widespread use of prostate-specific antigen (PSA) testing has dramatically changed the epidemiology of prostate cancer. Growing incidence rates have been documented in almost all western countries following the increased usage of PSA screening. In the United States after a period of huge increase in incidence, rates have decreased to values lower than those of the pre-PSA era. Similar changes have been documented also in the area of the Tuscany Cancer Registry, central Italy, where prostate cancer incidence rates doubled from the early 1990s to 2003 and afterwards decreased. This is the first evidence, to our knowledge, of a decline in prostate cancer incidence in Italy following the screening-related increase.

    Population-level disease metrics are critical to guide the distribution of resources and implementation of public health initiatives. Internet search data reflect population interest in health topics and may be an alternative metric of disease characteristics when traditional sources are lacking, such as in basal and squamous cell carcinomas, which are not included in national cancer registries. However, these data are not yet well validated or understood. To evaluate whether state-specific normalized internet search volume correlates with incidence and mortality rates of common cancers in the United States, including melanoma. This was a cross-sectional analysis of Google search volume index data and US cancer incidences and mortalities of 8 of the most incident cancers in the United States in 2009 to 2013, at the state level, per the National Program of Cancer Registries. Participants were people performing Google searches and patients diagnosed as having cancers reported to cancer registries. Correlation between Google search volumes, normalized to total Google search volume, and National Program of Cancer Registries recorded cancer incidence and mortality rates. By state, relative Google search volume statistically significantly correlated with cancer incidence rates in 5 of 8 commonly diagnosed cancers in the United States (colon cancer: R = 0.61; P search volume also correlated with mortality rates. Population-level internet search behavior may be a valuable real-time tool to estimate cancer incidence and mortality rates, especially for cancers not included in national registries, such as basal and squamous cell carcinomas.

    This study assessed trends in the incidence of and survival rates for oral cavity cancer in the Korean population. Data from the Korea Central Cancer Registry were extracted for 10,282 patients diagnosed with oral cavity cancer (C01-C06) between 1999 and 2010 to evaluate the age-standardised incidence rate, annual percentage change (APC) and 5-year relative survival rate (RSR) according to gender and age. In males, the incidence rate slightly decreased [APC of -0.2% (P = 0.6427)]; in females, the incidence rate increased [APC of 3.1% (P oral tongue cancer (C02) significantly increased [APC of 2.2% and 4.1%, respectively (P oral tongue cancer incidence was most prominent in the younger age group (cancer increased only among males [APC of 4.8% (P oral cavity cancer in females increased, whereas it stabilised or decreased in males. However, the incidence of oral tongue cancer increased in both males and females, especially in the younger age group. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Cervical cancer is a predominantly human papillomavirus (HPV)-driven disease worldwide. However, its incidence is unexplainably low in western Asia, including Saudi Arabia. Using this paradigm, we investigated the role of HPV infection rate and host genetic predisposition in TP53 G72C single nucleotide polymorphism (SNP) presumed to affect cancer incidence. Patients treated between 1990 and 2012 were reviewed, and a series of 232 invasive cervical cancer cases were studied and compared with 313 matched controls without cancer. SNP was genotyped by way of direct sequencing. HPV linear array analysis was used to detect and genotype HPV in tumor samples. The incidence of cervical cancer revealed bimodal peaks at 42.5 years, with a slighter rebound at 60.8 years. Among all cases, 77% were HPV-positive and 16 HPV genotypes were detected-mostly genotypes 16 (75%) and 18 (9%)-with no difference by age, histology, or geographical region. Although the TP53 G72C genotype was not associated with overall cervical cancer risk, it was significantly associated with HPV positivity (odds ratio, 0.57; 95% confidence interval, 0.36-0.90; P = .016). Furthermore, the variant C allele was significantly overtransmitted in the population (P Cervical cancer incidence displays bimodal curve peaking at a young age with secondary rebound at older age. The combination of relative low HPV infection and variant TP53 72C allele overtransmission provide a plausible explanation for the low incidence of cervical cancer in our population. Therefore, HPV screening and host SNP genotyping may provide more relevant biomarkers to gauge the risk of developing cervical cancer.

    Full Text Available Background: Liver Cancer (LC is one of the most common cancers in the worldwide. This cancer is considered as the fifth most common cancer in male and the ninth most common cancer in female. However, socioeconomic factors and morbidity and mortality of cancer are linked by sophisticated and flexible pathways. We were investigated the association between incidence and mortality of LC with the Human Development Index (HDI in European countries in 2012. Methods: This study was an ecologic study in European countries for assessment the correlation between Age-Specific Incidence Rate (ASIR and Age-Specific Mortality Rate (ASMR of LC with HDI and its details including: Life expectancy at birth, Mean years of schooling and Gross National Income (GNI per capita. We used of Pearson correlation method for appraisement the association between HDI and its components with ASIR and ASMR. Data of study was analyzed by SPSS15 statistical analysis software; the significance level of the tests was considered P˂0.05. Results: Generally in 2012, European countries have recorded 63,462 new cases of LC, crude rate was 8.6 and ASIR was 4.3 per 100,000. On the other hand in Europe countries in 2012, 62,191 cases of deaths were occurred due to LC, crude rate was 8.4 and ASMR was 3.9 per 100,000. Strong positive Correlation was observed between ASIR and ASMR (r = 0.848; P ≤ 0.001. HDI have weak negative correlation with ASIR of LC (r = - 0.194; P = 0.230, and strong negative correlation with ASMR of LC(r= - 0.515; P = 0.001. Conclusion: Increase in the human development index was associated with reduce in incidence and mortality of LC.

    The effect of high-flux (HF) dialysis on mortality rates could vary with the duration of dialysis. We evaluated the effects of HF dialysis on mortality rates in incident and prevalent hemodialysis (HD) patients. Incident and prevalent HD patients were selected from the Clinical Research Center registry for end-stage renal disease (ESRD), a Korean prospective observational cohort study. Incident HD patients were defined as newly diagnosed ESRD patients initiating HD. Prevalent HD patients were defined as patients who had been receiving HD for > 3 months. The primary outcome measure was all-cause mortality. This study included 1,165 incident and 1,641 prevalent HD patients. Following a median 24 months of follow-up, the mortality rates of the HF and low-flux (LF) groups did not significantly differ in the incident patients (hazard ratio [HR], 1.046; 95% confidence interval [CI], 0.592 to 1.847; p = 0.878). In the prevalent patients, HF dialysis was associated with decreased mortality compared with LF dialysis (HR, 0.606; 95% CI, 0.416 to 0.885; p = 0.009). HF dialysis was associated with a decreased mortality rate in prevalent HD patients, but not in incident HD patients.

    Numerous studies report that cancer prevalence in patients with schizophrenia might be different from the general population, but findings remain controversial. Our updated meta-analysis of cohort studies aims to analyze the data from cohort studies concerning the incidence risk of overall cancer and some site-specific cancers in patients with schizophrenia. We performed a systemic search through electronic databases. Cohort studies evaluating and describing the cancer incidence among patients with schizophrenia were included. Pooled risk ratios (RRs) were calculated for assessing the incidence risk of cancer. There were 16 cohort studies included in this meta-analysis, which combined a total of 480,356 participants with schizophrenia and 41,999 cases of cancer. Results showed that there was a slight significant decreased overall risk ratio of cancer incidence among patients with schizophrenia (RR=0.90, 95% CI 0.81-0.99). When stratified by cancer site and gender, there were significant decreased incidence risk rates of colorectal cancer (RR=0.82, 95% CI 0.69-0.98) and prostate cancer (RR=0.55, 95% CI 0.42-0.71) in those patients, moreover, the incidence rate of colorectal cancer decreased significantly in male patients (RR=0.89, 95% CI 0.81-0.98), and the incidence rate of lung cancer increased significantly in female patients (RR=1.12, 95% CI 1.01-1.25). The incidence risk of some cancers was reduced in patients with schizophrenia. Gender and type of cancer were two important confounding factors contributed to the heterogeneity that required adjustment in our cancer incidence meta-analysis. Copyright © 2017 Elsevier B.V.

    Inflammatory bowel disease is a global disease in the 21st century. We aimed to assess the changing incidence and prevalence of inflammatory bowel disease around the world. We searched MEDLINE and Embase up to and including Dec 31, 2016, to identify observational, population-based studies reporting the incidence or prevalence of Crohn's disease or ulcerative colitis from 1990 or later. A study was regarded as population-based if it involved all residents within a specific area and the patients were representative of that area. To be included in the systematic review, ulcerative colitis and Crohn's disease needed to be reported separately. Studies that did not report original data and studies that reported only the incidence or prevalence of paediatric-onset inflammatory bowel disease (diagnosis at age prevalence (69 studies) of Crohn's disease and ulcerative colitis. We used temporal trend analyses to report changes as an annual percentage change (APC) with 95% CI. We identified 147 studies that were eligible for final inclusion in the systematic review, including 119 studies of incidence and 69 studies of prevalence. The highest reported prevalence values were in Europe (ulcerative colitis 505 per 100 000 in Norway; Crohn's disease 322 per 100 000 in Germany) and North America (ulcerative colitis 286 per 100 000 in the USA; Crohn's disease 319 per 100 000 in Canada). The prevalence of inflammatory bowel disease exceeded 0·3% in North America, Oceania, and many countries in Europe. Overall, 16 (72·7%) of 22 studies on Crohn's disease and 15 (83·3%) of 18 studies on ulcerative colitis reported stable or decreasing incidence of inflammatory bowel disease in North America and Europe. Since 1990, incidence has been rising in newly industrialised countries in Africa, Asia, and South America, including Brazil (APC for Crohn's disease +11·1% [95% CI 4·8-17·8] and APC for ulcerative colitis +14·9% [10·4-19·6]) and Taiwan (APC for Crohn's disease +4·0% [1

    Breast cancer is diagnosed more frequently among urban than rural women in China; however, the incidence among women in Shijiazhuang is unknown. As registered Chinese citizens are entitled to complete public medical insurance coverage, the incidence rate was estimated using reimbursement records of first hospitalization. Breast cancer is the most common cancer among women in Shijiazhuang. The crude rate and age-standardized incidence rates by China (ASRC) and world (ASRW) standards were 59.6, 48.5 and 45.5/100 000 in 2012. Mean age at diagnosis was 55.1 years. Incidence increased with age, peaking at 165.1 at 70-74. In comparison with urban women in other Chinese cities, incidence in Shijiazhuang was similar to Shanghai (ASRC 46.6) and Suzhou (ASRW 45). When compared with 31 other Chinese cities, Shijiazhuang ranked second highest behind Guangzhou (ASRW 46.6), and the ASRW correlated significantly with gross domestic product per capita among the 32 cities. The breast cancer ASRW in Shijiazhuang was 2.7 times the rate of 41 rural Chinese counties (17). When compared with GLOBOCAN 2012 data according to the Human Development Index, breast cancer incidence in Shijiazhuang matched countries with a high human development index (ASRW 45.2). Breast cancer incidence in Shijiazhuang in 2012 was the highest in China, matching the rate in countries with high social economic development. This rate may continue to rise, parallel with urbanization, and may be associated with changing reproductive patterns and Westernization.

    Increased rates of solid organ cancers post-liver transplantation have been reported, but the contribution of environmental factors and immunosuppressive therapy is not clear. This study's aims were to compare the incidence of de novo solid organ cancers after liver transplantation; identify risk factors independent of immunosuppressive therapy associated with these cancers; and assess the influence of calcineurin inhibitors on the appearance of these cancers. This single-centre study from 1991 to 2008 included 465 liver recipients who had survived for ≥1 year. Gross incidence rates were standardized by age and sex, using the global population as a reference. In addition, 322 of the 465 patients treated for ≥1 year with calcineurin inhibitors were studied. Sixty-five (13.9%) of the 465 patients developed de novo solid cancers. The overall relative risk was 3.7. Significantly increased relative risks were observed for digestive, oesophageal, colorectal, oral and lung cancers, but not for genito-urinary and breast cancers. Among the 65 patients who developed solid organ cancers, 43 died (66.1%), 41 from cancer. The two independent risk factors were pretransplant smoking [P cancers. Tacrolimus exposure level was a risk factor for de novo solid cancers [P < 0.0001; OR = 15.3 (4.5; 52.2)].

    Age-specific disease incidence rates are typically estimated from longitudinal data, where disease-free subjects are followed over time and incident cases are observed. However, longitudinal studies have substantial cost and time requirements, not to mention other challenges such as loss to follow up. Alternatively, cross-sectional data can be used to estimate age-specific incidence rates in a more timely and cost-effective manner. Such studies rely on self-report of onset age. Self-reported onset age is subject to measurement error and bias. In this paper, we use a Bayesian bivariate smoothing approach to estimate age-specific incidence rates from cross-sectional survey data. Rates are modeled as a smooth function of age and lag (difference between age and onset age), with larger values of lag effectively down weighted, as they are assumed to be less reliable. We conduct an extensive simulation study to investigate the extent to which measurement error and bias in the reported onset age affects inference using the proposed methods. We use data from a national headache survey to estimate age- and gender-specific migraine incidence rates. (c) 2010 John Wiley & Sons, Ltd.

    In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including data on incidence, mortality, survival, and screening. Approximately 231,840 new cases of invasive breast cancer and 40,290 breast cancer deaths are expected to occur among US women in 2015. Breast cancer incidence rates increased among non-Hispanic black (black) and Asian/Pacific Islander women and were stable among non-Hispanic white (white), Hispanic, and American Indian/Alaska Native women from 2008 to 2012. Although white women have historically had higher incidence rates than black women, in 2012, the rates converged. Notably, during 2008 through 2012, incidence rates were significantly higher in black women compared with white women in 7 states, primarily located in the South. From 1989 to 2012, breast cancer death rates decreased by 36%, which translates to 249,000 breast cancer deaths averted in the United States over this period. This decrease in death rates was evident in all racial/ethnic groups except American Indians/Alaska Natives. However, the mortality disparity between black and white women nationwide has continued to widen; and, by 2012, death rates were 42% higher in black women than in white women. During 2003 through 2012, breast cancer death rates declined for white women in all 50 states; but, for black women, declines occurred in 27 of 30 states that had sufficient data to analyze trends. In 3 states (Mississippi, Oklahoma, and Wisconsin), breast cancer death rates in black women were stable during 2003 through 2012. Widening racial disparities in breast cancer mortality are likely to continue, at least in the short term, in view of the increasing trends in breast cancer incidence rates in black women. © 2015 American Cancer Society.

    Shoulder dislocations present a potentially debilitating injury for soldiers and other groups of physically active adults. The purpose of this study was to determine the 10-yr incidence rate of shoulder dislocations in soldiers, the percentage with recurrent instability, and risk factors for these injuries. This retrospective cohort study used medical encounter data from U.S. Army soldiers to calculate the 10-yr incidence rate for shoulder dislocations and the percentage of chronic or recurrent injuries >3 months and ≤2 yr after the initial diagnosis. A Cox proportional hazards model was constructed using demographic variables (age, race, education level, marital status, and sex) to determine incidence rate ratios for risk factors related to shoulder dislocation. Logistic regression was used to calculate odds ratio for risk factors for recurrent injury, including concurrent diagnoses (brachial plexus or peripheral nerve injuries and fractures of the scapula or proximal humerus). There were 15,426 incident shoulder dislocations, with a 10-yr incidence rate of 3.13 per 1000 person-year. Soldiers ≤40 yr old showed greater risk for injury compared with those older than 40 yr. The incidence rate ratio for males compared with females was 1.64, 95% confidence interval = 1.55-1.74. Recurrent injury occurred in 28.7% of cases. Concurrent axillary nerve injury (odds ratio = 3.64, 95% confidence interval = 1.56-8.46) and age ≤35 yr were associated with greater risk of recurrence. Within the active duty U.S. Army, men and younger individuals showed greater risk for shoulder dislocations. Over one-quarter of incident cases became recurrent. Axillary nerve injuries and younger age increased the odds of recurrent injury.

    To offer basic data related to the prevention of child sexual abuse, we conducted a Meta-analysis on the national incidence rate on child sexual abuse in the country. Publications between 2000 and 2013 were extracted from PubMed, Springer Link, Elsevier-SDOL, Chinese Biomedical Database (CBM), China National Knowledge Infrastructure (CNKI), Chinese Science & Technology journal database (VIP), Wanfang Databases, China master's Theses Full-text Database and China Conference Papers Full-text Database. Observational studies which containing the incidence rate of child sexual abuse were included. We used the Loney criteria to evaluate the quality of searched publications. The Meta incidence rate was estimated using the Stata software. Subgroup analysis were undertaken on gender issues. Sensitivity analysis were performed to evaluate the impact of types or qualities to the research objects. Fifteen papers were included in this Meta-analysis, with a sample size of 16 682. The combined incidence rate of child sexual abuse was 18.20% (95%CI:13.74%-22.66%). For injured persons, girls had a higher incidence rate on child sexual abuse (11.22%) than boys (8.25%) in terms of contact sexual abuse, but no significant difference on gender was found in the prevalence rates of global and un-contact sexual abuse. Data from sensitivity analysis revealed that the quality or types of the objects slightly affected the incidence rate of traffic injuries. of this study indicated that child sexual abuse was common and serious in China, suggesting that prevention and control programs on childhood abuse should be emphasized and promoted.

    The objective of cervical cancer screening is to lower the incidence and mortality rates of the disease. This study evaluates the effectiveness of cervical screening and the UICC and EC screening recommendations based on the Nordic screening experience. The study analyzes the features of the Icelandic and the Nordic screening programs and the observed trends in the incidence and mortality rates in these countries through 1995. Organized screening started in all the Nordic countries soon after 1960 and had nation-wide coverage in all these countries, except in Denmark (45% coverage in 1991), by around 1973 but in Norway screening was only spontaneous up to late in 1994. Up to 1985 the target age group and screening interval were most intensive in Iceland, followed by Finland, Sweden and Denmark. All countries except Finland lowered the lower age limit and intensified the screening intervals after 1985. Through the period 1986-1995 the reduction in both the mortality and the incidence rates was greatest in Iceland (mortality: 76% and incidence: 67%) and Finland (73% and 75%, respectively), intermediate in Sweden (60% and 55%, respectively) and Denmark (55% and 54%, respectively), and lowest in Norway (43% and 34%, respectively). The age-specific incidence in the 20-29 age group has been increasing since 1971 in all the Nordic countries, except in Finland, where the yearly registered age-specific incidence has been increasing in the targeted 30-54 age group since 1991. In Iceland screening has greatly affected the rate of all stages of squamous cell carcinoma, but not the rate of adeno- and adenosquamous carcinomas. In fact the rate of adenocarcinoma has been increasing. Organized screening is more effective than spontaneous screening in reducing the risk of cervical cancer. Although differences in environmental, biological and ethnic factors may call for different screening strategies, screening should preferably start soon after age 20 with a screening interval of 2

    Mexico diabetes prevalence has increased dramatically in recent years. However, no national incidence estimates exist, hampering the assessment of diabetes trends and precluding the development of burden of disease analyses to inform public health policy decision-making. Here we provide evidence regarding current magnitude of diabetes in Mexico and its future trends. We used data from the Mexico National Health and Nutrition Survey, and age-period-cohort models to estimate prevalence and incidence of self-reported diagnosed diabetes by age, sex, calendar-year (1960-2012), and birth-cohort (1920-1980). We project future rates under three alternative incidence scenarios using demographic projections of the Mexican population from 2010-2050 and a Multi-cohort Diabetes Markov Model. Adult (ages 20+) diagnosed diabetes prevalence in Mexico increased from 7% to 8.9% from 2006 to 2012. Diabetes prevalence increases with age, peaking around ages 65-68 to then decrease. Age-specific incidence follows similar patterns, but peaks around ages 57-59. We estimate that diagnosed diabetes incidence increased exponentially during 1960-2012, roughly doubling every 10 years. Projected rates under three age-specific incidence scenarios suggest diabetes prevalence among adults (ages 20+) may reach 13.7-22.5% by 2050, affecting 15-25 million individuals, with a lifetime risk of 1 in 3 to 1 in 2. Diabetes prevalence in Mexico will continue to increase even if current incidence rates remain unchanged. Continued implementation of policies to reduce obesity rates, increase physical activity, and improve population diet, in tandem with diabetes surveillance and other risk control measures is paramount to substantially reduce the burden of diabetes in Mexico.

    This study aimed to evaluate the epidemiology of hepatitis A in Korea from 2002 to 2012 using age-period-cohort analyses. We used claims data from the Korean National Health Insurance Corporation for the entire population. Census data from 2010 were used as the standard population. The incidence of hepatitis A was assumed to have a Poisson distribution, and the models and effects were evaluated using the intrinsic estimator method, the likelihood ratio, and the Akaike information criterion. The incidence of hepatitis A gradually increased until 2007 (from 17.55 to 35.72 per 100,000 population) and peaked in 2009 (177.47 per 100,000 population). The highest incidence was observed among 27-29-year-old individuals when we omitted data from 2005 to 2007. From 2005 to 2007, the peak incidence was observed among 24-26-year-old individuals, followed by 27-29-year-olds. The best model fits were observed when the age-period-cohort variables were all considered at the same time for males, females, and the whole population. The incidence of hepatitis A exhibited significant age-period-cohort effects; its incidence peaked in 2009 and was especially high among Koreans 20-39 years of age. These epidemiological patterns may help predict when high incidence rates of hepatitis A may occur in developing countries during their socioeconomic development.

    During the past decades, an increasing incidence of thyroid cancer (TC) has been reported worldwide. In Argentina there is no national cancer registry, and its incidence has therefore not been established. The aim of our study was to determine the incidence of TC in the province of Neuquén and to compare it to that reported in the literature. The medical records of 229 patients admitted over a period of 12 years (2001 to 2012) were used for data analysis. Tumor size, age, sex, and histological type were evaluated. The study period was divided into four three-year periods, and differences in each of these features were analyzed. We found an incidence of 4.72/100,000 inhabitants/year, and almost all patients had papillary TC. TC was five times more common in females as compared to males (7.78 and 1.55 respectively). Mean tumor size was 22.2 ± 1.1 mm. Tumor size was significantly greater in men (31.8 ± 3.7 mm) than in women (20.4 ± 1.0 mm). When grouped by three-year periods, a higher number of cases was found in the last one (47, 49, 49 and 84 respectively). As regards tumor distribution by size, there was a significant decrease in mean tumor size in the fourth period and an increase in the proportion of tumors <10mm. We report an increase in TC incidence in the Argentinean province of Neuquén which is similar to the overall increase reported in the international literature. Copyright © 2014 SEEN.

    Context National efforts to measure hospital performance for cardiac arrest have focused on case survival, with the hope of improving survival after cardiac arrest. However, it is plausible that hospitals with high case-survival rates do a poor job of preventing cardiac arrests in the first place. Objective To describe the association between inpatient cardiac arrest incidence and survival rates. Design, Setting, and Patients Within a large, national registry, we identified hospitals with at least 50 adult in-hospital cardiac arrest cases between January 1, 2000 and November 30, 2009. We used multivariable hierarchical regression to evaluate the correlation between a hospital’s cardiac arrest incidence rate and its case-survival rate after adjusting for patient and hospital characteristics. Main Outcome Measure The correlation between a hospital’s incidence rate and case-survival rate for cardiac arrest. Results Of 102,153 cases at 358 hospitals, the median hospital cardiac arrest incidence rate was 4.02 per 1000 admissions (IQR: 2.95 to 5.65 per 1000 admissions), and the median hospital case-survival rate was 18.8% (IQR: 14.5% to 22.6%). In crude analyses, hospitals with higher case-survival rates also had lower cardiac arrest incidence (correlation of -0.16; P=0.003). This relationship persisted after adjusting for patient characteristics (correlation of -0.15; P=0.004). After adjusting for potential mediators of this relationship (i.e., hospital characteristics), the relationship between incidence and case-survival was attenuated (correlation of -0.07; P=0.18). The one modifiable hospital factor that most attenuated this relationship was a hospital’s nurse-to-bed ratio (correlation of -0.12; P=0.03). Conclusions Hospitals with exceptional rates of survival for in-hospital cardiac arrest are also better at preventing cardiac arrests, even after adjusting for patient case-mix. This relationship is partially mediated by measured hospital attributes

    ABSTRACT OBJECTIVE Quantify, for both genders, the correlation between the depression incidence rate and the unemployment rate in Portugal between 1995 and 2013. METHODS An ecological study was developed to correlate the evolution of the depression incidence rates estimated by the General Practitioner Sentinel Network and the annual unemployment rates provided by the National Statistical Institute in official publications. RESULTS There was a positive correlation between the depression incidence rate and the unemployment rate in Portugal, which was significant only for males (R2 = 0.83, p = 0.04). For this gender, an increase of 37 new cases of depression per 100,000 inhabitants was estimated for each 1% increase in the unemployment rate between 1995 and 2013. CONCLUSIONS Although the study design does not allow the establishment of a causal association between unemployment and depression, the results suggest that the evolution of unemployment in Portugal may have had a significant impact on the level of mental health of the Portuguese, especially among men.

  16. Association of arsenic exposure with lung cancer incidence rates in the United States.

    Directory of Open Access Journals (Sweden)

    Joseph J Putila

    Full Text Available Although strong exposure to arsenic has been shown to be carcinogenic, its contribution to lung cancer incidence in the United States is not well characterized. We sought to determine if the low-level exposures to arsenic seen in the U.S. are associated with lung cancer incidence after controlling for possible confounders, and to assess the interaction with smoking behavior.Measurements of arsenic stream sediment and soil concentration obtained from the USGS National Geochemical Survey were combined, respectively, with 2008 BRFSS estimates on smoking prevalence and 2000 U.S. Census county level income to determine the effects of these factors on lung cancer incidence, as estimated from respective state-wide cancer registries and the SEER database. Poisson regression was used to determine the association between each variable and age-adjusted county-level lung cancer incidence. ANOVA was used to assess interaction effects between covariates.Sediment levels of arsenic were significantly associated with an increase in incident cases of lung cancer (P<0.0001. These effects persisted after controlling for smoking and income (P<0.0001. Across the U.S., exposure to arsenic may contribute to up to 5,297 lung cancer cases per year. There was also a significant interaction between arsenic exposure levels and smoking prevalence (P<0.05.Arsenic was significantly associated with lung cancer incidence rates in the U.S. after controlling for smoking and income, indicating that low-level exposure to arsenic is responsible for excess cancer cases in many parts of the U.S. Elevated county smoking prevalence strengthened the association between arsenic exposure and lung cancer incidence rate, an effect previously unseen on a population level.

    In the context of global climate change, carbon taxes, which vary positively with the carbon content of fuels, are seen as one of the main mitigative alternatives.. The incidence of this taxation will impact the relative prices of the different oil products and, possibly, change the demand curves for these products. Also, it will impact oil companies, which will have to adapt themselves to this new policy, so as to avoid, or to minimize, market share losses. However, only in the long term more complex changes in the market structures will be observed. As such, this paper aims at analyzing the relationships between the consumption of oil products in the short and long terms, and their corresponding consumers' income and price elasticities of demand due to carbon taxation, so as to assess their impacts on the World Petroleum Industry (WPI).

    The purpose of this study is to provide a detailed report on cancer incidence in Turkey, a relatively large country with a population of 72 million. We present the estimates of the cancer burden in Turkey for 2006, calculated using data from the eight population based cancer registries which have been set up in selected provinces representative of sociodemographic patterns in their regions. We calculated age specific and age adjusted incidence rates (AAIR-world standard population) for each of registries separately. We assigned a weighting coefficient for each registry proportional to the population size of the region which the registry represents. We pooled a total of 24,428 cancers (14,581 males, 9,847 females). AAIRs per 100 000 were: 210.1 in men and 129.4 in women for all cancer sites excluding non-melanoma skin cancer. The AAIR per 100 000 men was highest for lung cancer (60.3) followed by prostate (22.8), bladder (19.6), stomach (16.3) and colo-rectal (15.4) cancers. Among women the rate per 100 000 was highest for breast cancer (33.7) followed by colorectal (11.5), stomach (8.8), thyroid (8.8) and lung (7.7). The most striking findings about the cancer incidence in the provinces were the high incidence rates for stomach and esophageal cancers in Erzurum and high stomach cancer incidence rates in Trabzon for both sexes. We are thus able to present the most accurate and realistic estimations for cancer incidence in Turkey so far. Lung, prostate, bladder, stomach, colorectal, larynx cancers in men and breast, colorectal, stomach, thyroid, lung, corpus uteri cancers in women are the leading cancers respectively. This figure shows us tobacco related cancers, lung, bladder and larynx, predominate in men. Concurrently, we analyzed the data for each province separately, giving us the opportunity to present the differences in cancer patterns among provinces.

    Biomechanical analyses support the theory that thoracic spine hyperkyphosis may increase risk of new vertebral fractures. While greater kyphosis was associated with an increased rate of incident vertebral fractures, our analysis does not show an independent association of kyphosis on incident fracture, after adjustment for prevalent vertebral fracture. Excessive kyphosis may still be a clinical marker for prevalent vertebral fracture. Biomechanical analyses suggest hyperkyphosis may increase risk of incident vertebral fracture by increasing the load on vertebral bodies during daily activities. We propose to assess the association of kyphosis with incident radiographic vertebral fracture. We used data from the Fracture Intervention Trial among 3038 women 55-81 years of age with low bone mineral density (BMD). Baseline kyphosis angle was measured using a Debrunner kyphometer. Vertebral fractures were assessed at baseline and follow-up from lateral radiographs of the thoracic and lumbar spine. We used Poisson models to estimate the independent association of kyphosis with incident fracture, controlling for age and femoral neck BMD. Mean baseline kyphosis was 48° (SD = 12) (range 7-83). At baseline, 962 (32%) participants had a prevalent fracture. There were 221 incident fractures over a median of 4 years. At baseline, prevalent fracture was associated with 3.7° greater average kyphosis (95% CI 2.8-4.6, p < 0.0005), adjusting for age and femoral neck BMD. Before adjusting for prevalent fracture, each 10° greater kyphosis was associated with 22% increase (95% CI 8-38%, p = 0.001) in annualized rate of new radiographic vertebral fracture, adjusting for age and femoral neck BMD. After additional adjustment for prevalent fracture, estimated increased annualized rate was attenuated and no longer significant, 8% per 10° kyphosis (95% CI -4 to 22%, p = 0.18). While greater kyphosis increased the rate of incident vertebral fractures, our analysis does not

    Clinical observations showed a higher incidence rate of inguinal hernia (IH) in preterm infants. In this study, we calculated the incidence rate of preterm IH from the National Health Insurance Research Database (NHIRD) of Taiwan. From NHIRD, 92,308 subjects born in the year of 1997-2005 were randomly selected as the study cohort. The medical claims of these subjects from birth to 6th year of age were analyzed. Preterm births were defined using ICD code 765.1*. Risk factors such as birth weight, lung disorders, and ventilator supports before IH repairs were investigated. The risk of incarceration and bowel resection were also evaluated. From 92,308 subjects, 2560 preterm births were identified. IH was repaired in 231 preterm (9.02%) and 3650 term subjects (4.07%). Male (preterm 13.3% and non-preterm 6.3%) had more hernia repairs than female (preterm 3.8% and non-preterm 1.6%). The incidence rate of IH is 13.7% for those under 1500 g, 8.2% for those 1500-1999 g, 7.7% for those 2000-2499 g, and 6.3% for those above 2500 g. The incidence rate of IH in preterms with past history of lung disorders and ventilation supports is 8.7 and 13.6%, respectively. There was no significant difference in the incidences of incarceration and bowel resection between preterms and non-preterms. Birth weight under 2500 g is a significant risk factor for IH repairs. Other risk factors are male gender, past history of lung diseases, and ventilator supports.

    An examination of multiple primary cancers can provide insight into the etiologic role of genes, the environment, and prior cancer treatment on a cancer patient's risk of developing a subsequent cancer. Different rules for registering multiple primary cancers (MP) are used by cancer registries throughout the world making data comparisons difficult. We evaluated the effect of SEER and IARC/IACR rules on cancer incidence rates and trends using data from the SEER Program. We estimated age-standardized incidence rate (ASIR) and trends (1975-2011) for the top 26 cancer categories using joinpoint regression analysis. ASIRs were higher using SEER compared to IARC/IACR rules for all cancers combined (3 %) and, in rank order, melanoma (9 %), female breast (7 %), urinary bladder (6 %), colon (4 %), kidney and renal pelvis (4 %), oral cavity and pharynx (3 %), lung and bronchus (2 %), and non-Hodgkin lymphoma (2 %). ASIR differences were largest for patients aged 65+ years. Trends were similar using both MP rules with the exception of cancers of the urinary bladder, and kidney and renal pelvis. The choice of multiple primary coding rules effects incidence rates and trends. Compared to SEER MP coding rules, IARC/IACR rules are less complex, have not changed over time, and report fewer multiple primary cancers, particularly cancers that occur in paired organs, at the same anatomic site and with the same or related histologic type. Cancer registries collecting incidence data using SEER rules may want to consider including incidence rates and trends using IARC/IACR rules to facilitate international data comparisons.

    To study the population-based annual incidence rates of exudative, dry and all cases of symptomatic age-related macular degeneration (AMD) in different age and sex groups. This is a one year, prospective, population-based study on all consecutive new patients with AMD in the hospital district of Central Finland. The diagnosis was confirmed in all patients with slit lamp biomicroscopy, optical coherence tomography (OCT) using a Spectralis HRA + OCT device, and the Heidelberg Eye Explorer 1.6.2.0 program. Fluorescein angiograms were taken when needed. The population-based annual incidence rates of all cases of symptomatic AMD increased from 0.03% (95% CI, 0.01-0.05%) in the age group 50-59 years to 0.82% (95% CI, 0.55-1.09%) in the age group 85-89 years and were 0.2% (95% CI, 0.17-0.24%) in exudative, 0.11% (95% CI, 0.09-0.14%) in dry, and 0.32% (95% CI, 0.28-0.36%) in all cases of AMD in the age group 60 years and older. During the next 20 years in Central Finland the population-based annual incidence rates can be estimated to increase to 0.27% (95% CI, 0.24-0.30%) in exudative, to 0.13% (95% CI, 0.11-0.15%) in dry, and to 0.41% (95% CI, 0.37-0.45%) in all cases of AMD in the age group 60 years and older. The population-based annual incidence of AMD did not show statistically significant differences between males and females (p>0.1). The population-based age-group specific annual incidence rates of symptomatic AMD of this study may help to plan health care provision for patients of AMD.

    In studies using patient administrative data, the identification of the first (incident) acute myocardial infarction (AMI) in an individual is based on retrospectively excluding previous hospitalizations for the same condition during a fixed time period (lookback period [LP]). Our aim was to investigate whether the length of the LP used to identify the first AMI had an effect on trends in AMI incidence and subsequent survival in a nationwide study. All AMI events during 1994 to 2009 were retrieved from the Cardiovascular Disease in Norway project. Incident AMIs during 2004 to 2009 were identified using LPs of 10, 8, 7, 5, and 3 years. For each LP, we calculated time trends in incident AMI and subsequent 28-day and 1-year mortality rates. Results obtained from analyses using the LP of 10 years were compared with those obtained using shorter LPs. In men, AMI incidence rates declined by 4.2% during 2004 to 2009 (incidence rate ratio, 0.958; 95% confidence interval, 0.935-0.982). The use of other LPs produced similar results, not significantly different from the LP of 10 years. In women, AMI incidence rates declined by 7.3% (incidence rate ratio, 0.927; 95% confidence interval, 0.901-0.955) when an LP of 10 years was used. The decline was statistically significantly smaller for the LP of 5 years (6.2% versus 7.3%; P=0.02) and 3 years (5.9% versus 7.3%; P=0.03). The choice of LP did not influence trends in 28-day and 1-year mortality rates. The length of LP may influence the observed time trends in incident AMIs. This effect is more evident in older women. © 2015 American Heart Association, Inc.

    Cranial (head, jaw) tremors develop in a sizable number of essential tremor (ET) patients. They are particularly important because they are a significant source of embarrassment and are especially resistant to treatment. There are no data on the rate at which ET patients develop these cranial tremors. Our aim was to estimate the incidence rate of head and jaw tremors in ET. Cases, enrolled in a prospective, longitudinal study, were evaluated at baseline and one follow-up visit. The in-person evaluation included questionnaires and a videotaped neurological examination, which was reviewed by a senior movement disorder neurologist for the presence/absence of head and jaw tremors. The mean time between baseline and follow-up assessments was 6.3 ± 2.4 (median = 6.0; range = 1.5-12.4 years). Five (6.3%) of 79 cases developed head tremor by follow-up (incidence rate = 1,012 per 100,000 person years; 95% confidence interval [CI] = 0-3,219). Twelve (10.6%) of 113 cases developed jaw tremor by follow-up (incidence rate = 1,692 per 100,000 person years; 95% CI = 0-1,692). These epidemiological data were designed to assist physicians in counseling ET patients when they ask about their risks of developing cranial tremors. © 2014 S. Karger AG, Basel.

    Australia has a statutory incident reporting system for radiopharmaceutical maladministrations, but additional research into registry data is required for the purpose of quality improvement in nuclear medicine. We (i) used control charts to identify factors contributing to special cause variation (indicating higher than expected rates) in maladministrations and (ii) evaluated the impact of heterogeneous notification criteria and extent of underreporting among jurisdictions and individual facilities, respectively. Anonymised summaries of Australian Radiation Incident Register reports permitted calculation of national monthly maladministration notification rates for 2007-2012 and preparation of control charts. Multivariate logistic regression assessed the association of population, insurance and regulatory characteristics with maladministration notifications in each Australian State and Territory. Maladministration notification rates from two facilities with familiarity of notification processes and commitment to radiation protection were compared with those elsewhere. Special cause variation occurred in only 3 months, but contributed to 21% of all incidents (42 of 197 patients), mainly because of 'clusters' of maladministrations (n = 24) arising from errors in bulk radiopharmaceutical dispensing. Maladministration notification rates varied significantly between jurisdictions (0 to 12.2 maladministrations per 100 000 procedures (P < 0.05)) and individual facilities (31.7 vs 5.8 per 100 000; χ(2) = 40; 1 degree of freedom, P < 0.001). Unexpected increases in maladministration notifications predominantly relate to incident 'clusters' affecting multiple patients. The bulk preparation of radiopharmaceuticals is a vulnerable process and merits additional safeguards. Maladministration notification rates in Australia are heterogeneous. Adopting uniform maladministration notification criteria among States and Territories and methods to overcome underreporting are

    Full Text Available We explore the extent to which claim incidence in Disability Income Insurance (DII is affected by changes in the unemployment rate in Australia. Using data from 1986 to 2001, we fit a hurdle model to explore the presence and magnitude of the effect of changes in unemployment rate on the incidence of DII claims, controlling for policy holder characteristics and seasonality. We find a clear positive association between unemployment and claim incidence, and we explore this further by gender, age, deferment period, and occupation. A multinomial logistic regression model is fitted to cause of claim data in order to explore the relationship further, and it is shown that the proportion of claims due to accident increases markedly with rising unemployment. The results suggest that during periods of rising unemployment, insurers may face increased claims from policy holders with shorter deferment periods for white-collar workers and for medium and heavy manual workers. Our findings indicate that moral hazard may have a material impact on DII claim incidence and insurer business in periods of declining economic conditions.

    2016-06-01

    Hypospadias is a common congenital malformation. Surgical repair and management of the long-term consequences require a substantial amount of socioeconomic resources. It is generally accepted that genetic and environmental factors play a major role in the etiology of hypospadias. There have been contradictory reports on rising hypospadias rates, and regional and ethnical differences. The exact prevalence of hypospadias is of major interest for healthcare providers, clinical medicine, and research. To review the literature regarding the worldwide prevalence of hypospadias. Pubmed, EMBASE and Google were systematically screened for: hypospadias, congenital malformation, anomaly, incidence, prevalence, and epidemiology. Exclusion criteria were surgical and risk-factor studies. To give an additional comprehensive overview, prevalence data were harvested from the Annual Report of the International Clearinghouse Centre for Birth Defects Surveillance and Research. Prevalence was reported as per 10,000 live births. Data were available from 1910 to 2013. The median study period was 9 years (range: 1-36 years). Approximately 90,255,200 births have been screened in all studies. The mean prevalence were: Europe 19.9 (range: 1-464), North America 34.2 (6-129.8), South America 5.2 (2.8-110), Asia 0.6-69, Africa 5.9 (1.9-110), and Australia 17.1-34.8. There were major geographical, regional, and ethnical differences, with an extreme heterogeneity of published studies. Numerous studies showed an increasing prevalence; on the other hand, there were a lot of contradictory data on the prevalence of hypospadias. The summary table shows contradictory data from the five largest international studies available. There was huge literature available on the prevalence of hypospadias. Most data derived from Europe and North America. Many methodological factors influenced the calculation of an accurate prevalence, and even more of the true changes in prevalence over time (no generally accepted

    To systematically review the incidence rate of adverse drug reaction/event by Qingkailing injection. Such databases as the PubMed, EMbase, the Cochrane library, CNKI, VIP WanFang data and CBM were searched by computer from foundation to July 30, 2015. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data and cross check data. Then, Meta-analysis was performed by using the R 3.2.0 software, subgroup sensitivity analysis was performed based on age, mode of medicine, observation time and research quality. Sixty-three studies involving 9,793 patients with Qingkailing injection were included, 367 cases of adverse reactions/events were reported in total. The incidence rate of adverse reaction in skin and mucosa group was 2% [95% CI (0.02; 0.03)]; the digestive system adverse reaction was 6% [95% CI(0.05; 0.07); the injection site adverse reaction was 4% [95% CI (0.02; 0.07)]. In the digestive system as the main types of adverse reactions/events, incidence of children and adults were 4.6% [0.021 1; 0.097 7] and 6.9% [0.053 5; 0.089 8], respectively. Adverse reactions to skin and mucous membrane damage as the main performance/event type, the observation time > 7 days and ≤ 7 days incidence of 3% [0.012 9; 0.068 3] and 1.9% [0.007 8; 0.046 1], respectively. Subgroup analysis showed that different types of adverse reactions, combination in the incidence of adverse reactions/events were higher than that of single drug, the difference was statistically significant (P reactions occur, and clinical rational drug use, such as combination, age and other fators, and the influence factors vary in different populations. Therefore, clinical doctors for children and the elderly use special care was required for a clear and open spirit injection, the implementation of individualized medication.

    To examine whether vesicourethral reflux diagnosed by positioned instillation of contrast (PIC-VUR) shows clinical importance by comparing the incidence rates of febrile urinary tract infection (FUTI) before and after treatment of PIC-VUR. Beginning in 2001 we used a multi-institutional registry to prospectively enroll consecutive pediatric patients with a history of FUTI without VUR according to voiding cystourethrogram (VCUG) and yet who show PIC-VUR. Treatment of PIC-VUR was with prophylactic antimicrobials or antireflux surgery. The post-treatment occurrence of FUTI was tracked. A total of 14 centers enrolled 118 patients (mean age, 7.2 years; range, 0.5 to 20 years). Parents self-selected the treatment of PIC-VUR as endoscopic injection (104), ureteral reimplantation (3), or antimicrobial prophylaxis (11). Study intervals surveying for FUTI before PIC (mean, 12 months; range, 1 to 17 years) and after PIC treatment (mean, 11 months; range, 0 to 3 years) were not significantly different. Overall the incidence rate for FUTI decreased significantly from 0.16 per patient per month before PIC-VUR treatment to 0.008 per patient per month after treatment (rate ratio 20; 95% confidence interval 11 to 36). The post-treatment rate of FUTI in patients treated with antibiotics versus surgery was not significantly different (rate ratio 2.5; 95% confidence interval 0.33 to 27). The diagnosis of PIC-VUR is clinically important because children treated for PIC-VUR with either antimicrobial prophylaxis or surgery show a significant reduction in the incidence rate of FUTI. This is the basis for a current prospective study randomizing patients with PIC-VUR to treatment or observation.

    Full Text Available Background: Transmission of Mycobacterium tuberculosis (M. tuberculosis can occur in different ways. Furthermore, drug resistant in M. tuberculosis family is a major problem that creates obstacles in treatment and control of tuberculosis (TB in the world. One of the most prevalent families of M. tuberculosis is Haarlem, and it is associated with drug resistant. Our objectives of this study were to determine the prevalence and occurrence rate of M. tuberculosis Haarlem family multi-drug resistant (MDR in the worldwide using meta-analysis based on a systematic review that performed on published articles. Materials and Methods: Data sources of this study were 78 original articles (2002-2012 that were published in the literatures in several databases including PubMed, Science Direct, Google Scholar, Biological abstracts, ISI web of knowledge and IranMedex. The articles were systematically reviewed for prevalence and rate of MDR. Data were analyzed using meta-analysis and random effects models with the software package Meta R, Version 2.13 (P < 0.10. Results: Final analysis included 28601 persons in 78 articles. The highest and lowest occurrence rate of Haarlem family in M. tuberculosis was in Hungary in 2006 (66.20% with negative MDR-TB and in China in 2010 (0.8%, respectively. From 2002 to 2012, the lowest rate of prevalence was in 2010, and the highest prevalence rate was in 2012. Also 1.076% were positive for MDR and 9.22% were negative (confidence interval: 95%.0020. Conclusion: Many articles and studies are performed in this field globally, and we only chose some of them. Further studies are needed to be done in this field. Our study showed that M. tuberculosis Haarlem family is prevalent in European countries. According to the presence of MDR that was seen in our results, effective control programs are needed to control the spread of drug-resistant strains, especially Haarlem family.

    To study the effect on lung cancer incidence of a long exposure to low levels of radon, 500 male 3-months-old Sprague-Dawley rats, were exposed to a cumulative dose of 25 WLM of radon and its daughters, 6 hours a day, 5 days a week, during 18 months. Exposure conditions were controlled in order to maintain a defined PAEC: 42 x 10{sup 6} J.m{sup -3} (2 WL), in the range of domestic and environmental exposures. Animals were kept until they died or given euthanasia when moribund. Mean survival times were similar in both irradiated and control groups: 828 days (SD = 169) and 830 days (SD = 137), as well as lung cancer incidence, 0.60% at 25 WLM and 0.63% for controls. The incidence of lung lesions was compared statistically with controls and those previously obtained at cumulative exposures of 25 and 50 WLM delivered over a 4-6 month period, inducing a significant increase of lung cancer, 2.2% and 3.8% respectively. Such a comparison showed a decreased lung cancer incidence related to a decrease in the dose rate for low levels of radon exposure. (author).

    To analyse differences in myocardial infarction incidence, mortality and hospitalization rates, 28-day case-fatality and two-year prognosis using two myocardial infarction case definitions: the classical World Health Organization definition (1994) and the European Society of Cardiology/American College of Cardiology definition (2000), which added cardiac troponin as a diagnostic biomarker. Population-based cohort of 4170 consecutive myocardial infarction patients aged 35-74 years from Girona (Spain) recruited between 2002 and 2009. Incidence, mortality rates standardized to the European population and 28-day case-fatality were calculated. To estimate the association between case definition and prognosis, Cox models were fitted. Use of the 2000 European Society of Cardiology/American College of Cardiology definition significantly increased myocardial infarction incidence per 100,000 population (238.3 vs. 274.5 in men and 54.1 vs. 69.7 in women). Applying this definition decreased the 28-day case-fatality rate from 26.9% to 23.4% in men, and from 31.0% to 24.1% in women. In the acute phase, patients diagnosed only by increased troponins were significantly less treated with thrombolysis (34.4% vs. 2.0%), angiotensin-converting enzyme inhibitors (71.7% vs. 65.0%) and percutaneous coronary intervention (41.1% vs. 31.7%). Case-fatality at 28 days was significantly better in cases diagnosed only by troponin increase (0.2 % vs. 9.7%), but two-year cardiovascular mortality was higher (7.5% vs. 3.7%). Inclusion of cardiac troponins in myocardial infarction diagnosis increased annual incidence and decreased case-fatality. Diagnosis based only on increased troponins was associated with worse outcome. This group of patients at high risk of death should receive aggressive secondary prevention therapy. © The European Society of Cardiology 2014.

    To analyze the spatial distribution of suicide incidence rate in a residential municipality of the state of Espírito Santo (ES), Brazil, from 2003 to 2007. Ecologic study of the exploratory kind, based on secondary data. Deaths per suicide, which took place in each municipality of ES, were included in the data according to information provided by the Mortality Information System. For the spatial data analysis, a Bayesian approach was used (Global empirical and Local Bayesian ones) to correct epidemiological rates. Moran's I index was calculated to a worldwide spatial level dependence, and Local Moran (LISA) to a local spatial correlation. The following software applications were used: Excel; R 2.6.2; SPSS 11.5 and TerraView 3.3.1. The geographical localization of the municipalities that showed an incidence rate characterized as the average for suicide after adjustment (EBest Global) forms a corridor in the countryside. Some common characteristics among these municipalities are: a) immigration (Italians, Pomeranians/ Germans); b) rural population (average of 53%); c) supporting economy (agriculture, husbandry and livestock). A global and local spatial correlation was found among the municipalities (p identified the spatial context where the greatest death incidence rate per suicide occurred in the state of ES, during the mentioned period.

    Objective: To review the worldwide studies on natural history models among colorectal cancer (CRC), and to inform building a Chinese population-specific CRC model and developing a platform for further evaluation of CRC screening and other interventions in population in China. Methods: A structured literature search process was conducted in PubMed and the target publication dates were from January 1995 to December 2014. Information about classification systems on both colorectal cancer and precancer on corresponding transition rate, were extracted and summarized. Indicators were mainly expressed by the medians and ranges of annual progression or regression rate. Results: A total of 24 studies were extracted from 1 022 studies, most were from America (n=9), but 2 from China including 1 from the mainland area, mainly based on Markov model (n=22). Classification systems for adenomas included progression risk (n=9) and the sizes of adenoma (n=13, divided into two ways) as follows: 1) Based on studies where adenoma was risk-dependent, the median annual transition rates, from ' normal status' to ' non-advanced adenoma', 'non-advanced' to ' advanced' and ' advanced adenoma' to CRC were 0.016 0 (range: 0.002 2-0.020 0), 0.020 (range: 0.002-0.177) and 0.044 (range: 0.005-0.063), respectively. 2) Median annual transition rates, based on studies where adenoma were classified by sizes, into system of CRC mainly included LRD (localized/regional/distant, n=10), Dukes' (n=7) and TNM (n=3). When using the LRD classification, the median annual transition rates from ' localized' to ' regional' and ' regional' to 'distant' were 0.28 (range: 0.20-0.33) and 0.40 (range: 0.24-0.63), respectively. Under the Dukes' classification, the median annual transition rates appeared as 0.583 (range: 0.050-0.910), 0.656 (range: 0.280-0.720) and 0.830 (range: 0.630-0.865) from Dukes' A to B, B to C and C to Dukes' D, respectively. Again, when using the TNM classification, very limited transition rate

Methods: We identified all subjects aged 15–64 years who were listed for the first time in the Danish Psychiatric Register with a diagnosis of ATPDs (n = 3,350), SZ (n = 4,576) and BD (n = 3,200) in 1995–2008. Incidence rates and rate ratios (IRR; 95 % confidence interval) by gender and age...... were calculated. Results: The incidence of ATPDs was 6.7 per 100,000 person-years, similarly high for both genders (IRR 1.0; 0.9–1.1). Among the ATPD subtypes, polymorphic psychotic disorder was more common in females (IRR 1.4; 1.2–1.6) as opposed to those featuring schizophrenic symptoms, which tended...... to occur in younger males (IRR 1.4; 1.2–1.7). No significant gender difference was found for acute predominantly delusional disorder (IRR 1.0; 0.9–1.2), which had a later onset than any ATPD subtypes. SZ had an incidence twice as high in males (IRR 2.0; 1.9–2.2), and an earlier age of onset than ATPDs...

    BACKGROUND The relationship between socioeconomic status and cancer incidence in the United States has not traditionally been a focus of population-based cancer surveillance systems. METHODS Nearly 3 million tumors diagnosed between 2005 and 2009 from 16 states plus Los Angeles were assigned into 1 of 4 groupings based on the poverty rate of the residential census tract at time of diagnosis. The sex-specific risk ratio of the highest-to-lowest poverty category was measured using Poisson regression, adjusting for age and race, for 39 cancer sites. RESULTS For all sites combined, there was a negligible association between cancer incidence and poverty; however, 32 of 39 cancer sites showed a significant association with poverty (14 positively associated and 18 negatively associated). Nineteen of these sites had monotonic increases or decreases in risk across all 4 poverty categories. The sites most strongly associated with higher poverty were Kaposi sarcoma, larynx, cervix, penis, and liver; those most strongly associated with lower poverty were melanoma, thyroid, other nonepithelial skin, and testis. Sites associated with higher poverty had lower incidence and higher mortality than those associated with lower poverty. CONCLUSIONS These findings demonstrate the importance and relevance of including a measure of socioeconomic status in national cancer surveillance. Cancer 2014;120:2191–2198. © 2014 The Authors.

    To assess the prevalence of abortion among population groups and changes in rates between 2008 and 2014. We used secondary data from the Abortion Patient Survey, the American Community Survey, and the National Survey of Family Growth to estimate abortion rates. We used information from the Abortion Patient Survey to estimate the lifetime incidence of abortion. Between 2008 and 2014, the abortion rate declined 25%, from 19.4 to 14.6 per 1000 women aged 15 to 44 years. The abortion rate for adolescents aged 15 to 19 years declined 46%, the largest of any group. Abortion rates declined for all racial and ethnic groups but were larger for non-White women than for non-Hispanic White women. Although the abortion rate decreased 26% for women with incomes less than 100% of the federal poverty level, this population had the highest abortion rate of all the groups examined: 36.6. If the 2014 age-specific abortion rates prevail, 24% of women aged 15 to 44 years in that year will have an abortion by age 45 years. The decline in abortion was not uniform across all population groups.

    We characterize here a new nationwide incident cohort of multiple sclerosis from the US military-veteran population. This cohort provides an update to the only other US nationwide incidence study of multiple sclerosis performed during the 1970s. Medical records and data from the Department of Defense and Department of Veterans Affairs for cases of multiple sclerosis who served in the military between 1990, the start of the Gulf War era, and 2007 and who were service-connected for this disorder by the Department of Veterans Affairs from 1990 on, were reviewed. A total of 2691 patients were confirmed as having multiple sclerosis: 2288 definite, 190 possible, 207 clinically isolated syndrome and six neuromyelitis optica. Overall racial categories were White, Black and other, which included all Hispanics. There were 1278 White males and 556 females; 360 Black males and 296 females; and 200 others, 153 (77%) of whom were Hispanic. Mean age at onset of 30.7 years did not differ significantly by race or sex. Age at onset was 17-50 years in 99%, the same age range as 99% of the military. Average annual age specific (age 17-50 years) incidence rates per 100 000 for the entire series were 9.6 with 95% confidence interval of 9.3-10.0. Rates for Blacks were highest at 12.1 with confidence interval 11.2-13.1, Whites were 9.3 (interval 8.9-9.8) and others 6.9 (interval 6.0-7.9). For 83 Hispanics defined for 2000-07, the rate was 8.2 (interval 6.5-10.1). Much smaller numbers gave rates of 3.3 for Asian/Pacific Islanders and 3.1 for native Americans. Rates by sex for Whites were 7.3 and 25.8 male and female, respectively, for Blacks 8.4 and 26.3, and for Hispanics 6.6 and 17.0. Rates by service were high for Air Force (10.9) and Army (10.6), medium for Navy (9.1) and Coast Guard (7.9), and low for Marines (5.3). Relative risk of multiple sclerosis was 3.39 female:male and 1.27 Black:White. These new findings indicate that females of all races now have incidence rates for multiple

    OBJECTIVES Cancer continues to be the leading disease-related cause of death among children and adolescents in the United States. More current information is needed to describe recent cancer trends and identify demographic and geographic variations. METHODS We analyzed data from the National Program of Cancer Registries and Surveillance, Epidemiology, and End Results statewide registries representing 94.2% of the US population to identify cancers diagnosed among persons aged 0 to 19 years during 2001–2009. Age-adjusted rates and annual percentage change for trends were calculated. Data were stratified by age, gender, race, ethnicity, and geography. RESULTS We identified 120 137 childhood and adolescent cancer cases during 2001–2009 with an age-adjusted incidence rate of 171.01 per million. The overall rate of all cancers combined remained stable over time (annual percent change [APC], 0.3%; 95% confidence interval [CI], −0.1 to 0.7). There was an increase in the overall cancer trend among African American children and adolescents (APC, 1.3%; 95% CI, 0.2 to 2.5). An increasing trend for thyroid cancer was observed among both genders (APC, 4.9%; 95% CI, 3.2 to 6.6) and specifically among adolescents and those in the Northeast, South, and West regions of the United States. Renal carcinoma incidence was increasing significantly overall (APC, 5.4%; 95% CI, 2.8 to 8.1). Extracranial and extragonadal germ cell tumors and melanoma were both significantly decreasing. CONCLUSIONS This study reports the novel finding that renal carcinoma rates are increasing among children and adolescents. This study confirms that thyroid cancer rates are increasing and further describes rising cancer rates among African Americans. PMID:25201796

    This study was conducted to describe the trends and age-period-cohort effects on the incidence and mortality rate of cervical cancer in Korea. The incidence and mortality rate of cervical cancer among ≥ 20-year-old women from 1993 to 2012 were obtained from the Korea Central Cancer Registry and the Korean Statistical Information Service. Age-standardized rates were calculated and Joinpoint regression was used to evaluate the trends in the incidence and mortality rate. Age-period-cohort analysis was performed to investigate the independent effects of age, period and cohort. The incidence of cervical cancer decreased from 32.8 per 100,000 in 1993 to 15.9 per 100,000 in 2012 (annual percent change [APC], -3.9%; 95% confidence interval [CI], -4.2% to -3.6%). The mortality rate decreased from 5.2 per 100,000 in 1993 to 2.1 per 100,000 in 2012 (APC, -4.8%; 95% CI, -5.1% to -4.4%); however, the incidence and mortality rates among young women (age-period-cohort model of the incidence and mortality rate showed decreasing period effects between 1993 and 2008 and decreasing cohort effects between 1928 and 1973, while birth cohorts after 1973 exhibited slight increases in the incidence and mortality rate of cervical cancer. Recent decreases in the incidence and mortality rate of cervical cancer were due to decreases in the period and cohort effects, which reflect the implementation of a cancer screening program and changes in lifestyle. However, our findings also highlighted an increase in cohort effects on the incidence and mortality rate among young women born after 1973.

    Abstract. Background: The validity and reliability of suicide statistics have been questioned and few nationwide studies of deliberate self-harm have been presented. Aim: To calculate rates of deliberate self-harm in Denmark in order to investigate trends and assess the reliability of hospital records. Method: A register study based on all individuals recorded with an episode of deliberate self-harm or probable deliberate self-harm in nationwide registers during 1994–2011. Results: A substantial difference in the rates of deliberate self-harm and probable deliberate self-harm was noted for both genders. The average incidence rate of deliberate self-harm for women and men was 130.7 (95% CI = 129.6–131.8) per 100,000 and 86.9 (95% CI = 86.0–87.8) per 100,000, respectively. The rates of deliberate self-harm for women increased from 137.6 (95% CI = 132.9–142.3) per 100,000 in 1994 to 152.7 (95% CI = 147.8–157.5) in 2011. For a subgroup of younger women aged 15–24 years, an almost threefold increase was observed, IRR = 2.5 (95% CI = 2.4–2.7). The most frequently used method was self-poisoning. Conclusion: The rates of deliberate self-harm and probable deliberate self-harm differed significantly. An increased incidence of deliberate self-harm among young Danish women was observed, despite detection bias. An improved registration procedure of suicidal behavior is needed. PMID:27278571

    An elevated heart rate (HR) at rest at baseline is associated with an increased risk of incident heart failure (HF) and with greater cardiovascular event rates in patients with chronic HF. However, despite the high attributable risk of hypertension for HF, whether the in-treatment HR predicts incident HF in patients with treated hypertension has not been evaluated. The HR was evaluated on annual electrocardiograms from 9,024 patients with hypertension without HF who were treated with losartan- or atenolol-based regimens. During a mean follow-up of 4.7 ± 1.1 years, HF developed in 285 patients (3.2%). On multivariate Cox analyses adjusted for randomized treatment, the baseline risk factors for HF, baseline and in-treatment blood pressure, QRS duration, and electrocardiographic left ventricular hypertrophy, a greater in-treatment HR predicted a 45% greater adjusted risk of new HF for every 10-beats/min increase in the HR (95% confidence interval [CI] 34% to 57%) or a 159% greater risk of HF in patients with the persistence or development of a HR of ≥84 beats/min (95% CI 88% to 257%). In contrast, with adjustment for the same covariates, the baseline HR as a continuous variable was a significantly less powerful predictor of new HF (hazard ratio 1.15 per 10 beats/min, 95% CI 1.03 to 1.28) and a baseline HR of ≥84 beats/min did not predict new HF (hazard ratio 1.00, 95% CI 0.63 to 1.58). In conclusion, a greater in-treatment HR on the serial electrocardiograms predicts a greater risk of incident HF during antihypertensive treatment, independent of the covariates, in patients with hypertension with electrocardiographic left ventricular hypertrophy. These findings support serial HR assessment to improve the risk stratification of patients with hypertension. Copyright © 2012 Elsevier Inc. All rights reserved.

    To analyse the incidence, risk factors, aetiology, treatment and clinical evolution of young patients with stroke. Retrospective registry of patients aged 55 years or younger hospitalised in a stroke unit during 2014. We recorded the incidence rate for all strokes and analysed demographic data, risk factors, degree of stress, stroke type and aetiology, reperfusion treatments and clinical evolution. The study included 110 patients, the majority of whom were men (60.9%, 1.6:1 ratio). The incidence rate was 13.3% (110 of 830 strokes). Most of the patients had cardiovascular risk factors. Smoking was the most common risk factor (56.4%), followed by arterial hypertension (50%), dyslipidaemia (42.7%), obesity (33%), diabetes (18.2%) and emboligenic heart disease (12.7%). Some 64.3% of the heart disease cases and 51.1% of the dyslipidaemia cases were discovered during hospitalisation. Some 57.2% of the patients experienced psychosocial stress in the stage prior to the stroke. Some 83.6% of the stroke cases were ischaemic, 12.7% were haemorrhagic and 3.6% were venous sinus thrombosis. Of the ischaemic stroke cases, 30.4% were cryptogenic, 23.9% were lacunar, 16.3% were from uncommon causes, 15.2% were atherothrombotic and 14.1% were cardioembolic. Some 78.6% of the cerebral haemorrhage cases were hypertensive. Some 23.3% of the ischaemic stroke cases underwent reperfusion treatments in the acute phase, achieving levels of functional independence at 3 months of 62.5%. The majority of stroke events in patients 55 years of age or younger appear to be related to a high prevalence of classical cardiovascular risk factors and possibly to psychosocial stress.

    2016-09-12

    Data published from the United States have demonstrated that the use of cervical cerclage has fallen in the period 1998-2013. This is in contrast to recommendations in Australia. We examined this trend using data from the Australian Institute of Health and Welfare (AIHW). Retrospective population-based study. Data from the Australian Institute of Health and Welfare procedural database were used to determine the total number of cervical cerclage sutures inserted during the period 2004 to 2013. Population datasets were used to calculate age-stratified incidence rates of cerclage. There was a significant increase in the rate of cervical cerclage in women aged 25 to 34 years and in the 35 years and older age group. The incidence of preterm birth was stable for gestations of 32 to 36 weeks, but slightly increased in the 20 to 27 week and 28 to 31 week gestational age groups. Further research into cervical cerclage and the use of vaginal progesterone for the prevention of preterm birth would be valuable.

    Background Melanoma rates are rising among young women, possibly due to increasing ultraviolet radiation to previously protected body sites. Therefore, we examined melanoma incidence trends by age, gender, and body site. Descriptive methods were complemented with the age-period-cohort parameters net drift and longitudinal age trend. Methods Case and population data were obtained from the Surveillance, Epidemiology, and End Results 9 Registries Database (1975-2006). Net drift summarized the average annual percentage change in log-linear rates per year of calendar-time (or year of diagnosis). Longitudinal age trend summarized the average annual percentage change by attained age at diagnosis. Early-and late-onset melanomas have low and high longitudinal age trends, respectively. Results There were 105,829 melanomas diagnosed in the SEER 9 Registries. The overall age-adjusted incidence rate (IR)for melanoma was 17.7/100,000 person-years. Age specific IRs were greater among women than men prior to age 40 years. Among women, Irs decreased for all anatomic sites relative to the trunk. The highest net drift occurred in truncal lesions among women (net drift = 3.8%/year of calendar time; 95% CI = 3.5%-4.0%). The lowest longitudinal age trends also were observed for truncal lesions among women (longitudinal age trend = 5.4%/year of attained age; 95% CI = 5.1-5.7). Conclusions Though melanoma Irs overall have risen for decades, the combination of high net drift and low longitudinal age trend demonstrate that melanomas are rising preferentially on the trunk among young women. Impact Future surveillance and analytic studies should consider melanoma effect modification by age, gender, and body site. PMID:20826837

    Heart rate (HR) at rest is a well-known marker of cardiovascular morbidity and mortality. Results on the association between HR and incident atrial fibrillation (AF) have, however, been conflicting. Using digital electrocardiograms from 281,451 primary care patients, we aimed to describe...... the association between HR at rest and the hazards of incident AF. Secondary end points were death from all causes and pacemaker implantation. Data on drug use, co-morbidity, and outcomes were collected from nationwide administrative health care registries. During a median follow-up time of 8.4 years, 15......,666 subjects were observed to develop AF, of which 1,631 were lone AF. A HR at rest from 30 to 51 beats/min was associated with an adjusted hazard ratio of 1.16 (95% CI 1.06 to 1.27) for AF compared with the reference group (66 to 72 beats/min). From 72 beats/min and upward, the hazard ratio of AF increased...

    Updated information on the incidence of the principal cardiovascular diseases (CVD) and cardiovascular mortality is not available in Spain. We have studied the incidence rate of new cases of myocardial infarction, heart failure, stroke and cardiovascular mortality in the adult population in Sanlúcar de Barrameda (Spain). A community-based prospective follow-up study was conducted. The study enrolled 858 participants aged 50-75 years who were randomly selected from the population and followed-up for 5 years. Age and gender-adjusted incidence rates of cardiovascular disease and cardiovascular mortality were calculated, obtaining complete information for 855 participants. Prognostic risk factors of new cases of cardiovascular disease were obtained using Cox proportional hazard modeling. The community-based incidence rate of heart failure was 455/100.000 persons-year. The incidence of myocardial infarction, stroke and cardiovascular mortality (506, 216 and 225/100.000 persons-year, respectively) was also very elevated. Male gender, family history of early cardiovascular disease, diabetes, hypertension and sedentary life style were independent risk factors of cardiovascular disease. The community-based incidence rate of heart failure in Sanlúcar de Barrameda (Spain) is very high, and it is the first to be reported in Spain. The incidence of myocardial infarction is among the highest in Spain. Copyright © 2012 Elsevier España, S.L. All rights reserved.

    2017-03-01

    The 2014 Ebola outbreak in West Africa has exposed the need to connect modellers and those with relevant data as pivotal to better understanding of how the disease spreads and quantifying the effects of possible interventions. In this paper, we model and analyse the Ebola virus disease with non-linear incidence rate. The epidemic model created is used to describe how the Ebola virus could potentially evolve in a population. We perform an uncertainty analysis of the basic reproductive number R 0 to quantify its sensitivity to other disease-related parameters. We also analyse the sensitivity of the final epidemic size to the time control interventions (education, vaccination, quarantine and safe handling) and provide the cost effective combination of the interventions.

  17. An SIRS Epidemic Model with Vital Dynamics and a Ratio-Dependent Saturation Incidence Rate

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available This paper presents an investigation on the dynamics of an epidemic model with vital dynamics and a nonlinear incidence rate of saturated mass action as a function of the ratio of the number of the infectives to that of the susceptibles. The stabilities of the disease-free equilibrium and the endemic equilibrium are first studied. Under the assumption of nonexistence of periodic solution, the global dynamics of the model is established: either the number of infective individuals tends to zero as time evolves or it produces bistability in which there is a region such that the disease will persist if the initial position lies in the region and disappears if the initial position lies outside this region. Computer simulation shows such results.

    As more women survive breast cancer, long-term toxicities affecting their quality of life, such as lymphedema (LE) of the arm, gain importance. Although numerous studies have attempted to determine incidence rates, identify optimal diagnostic tests, enumerate efficacious treatment strategies and outline risk reduction guidelines for breast cancer-related lymphedema (BCRL), few groups have consistently agreed on any of these issues. As a result, standardized recommendations are still lacking. This review will summarize the latest data addressing all of these concerns in order to provide patients and health care providers with optimal, contemporary recommendations. Published incidence rates for BCRL vary substantially with a range of 2-65% based on surgical technique, axillary sampling method, radiation therapy fields treated, and the use of chemotherapy. Newer clinical assessment tools can potentially identify BCRL in patients with subclinical disease with prospective data suggesting that early diagnosis and management with noninvasive therapy can lead to excellent outcomes. Multiple therapies exist with treatments defined by the severity of BCRL present. Currently, the standard of care for BCRL in patients with significant LE is complex decongestive physiotherapy (CDP). Contemporary data also suggest that a multidisciplinary approach to the management of BCRL should begin prior to definitive treatment for breast cancer employing patient-specific surgical, radiation therapy, and chemotherapy paradigms that limit risks. Further, prospective clinical assessments before and after treatment should be employed to diagnose subclinical disease. In those patients who require aggressive locoregional management, prophylactic therapies and the use of CDP can help reduce the long-term sequelae of BCRL.

    We investigated the incidence and seasonal patterns of child maltreatment hospitalisations in Hong Kong. A retrospective study of subjects aged under 19 years with a primary diagnosis of child maltreatment admitted to hospitals in Hong Kong from 2001 to 2010. Data were retrieved from the centralised database of all 42 public hospitals in the Hospital Authority. Child maltreatment incidence rate. A consistent seasonal pattern was found for non-sexual maltreatment in children aged 6-18 years (p<0.001). Hospitalisations peaked in May and October but dipped in August and January. No significant seasonal patterns were found for sexual maltreatment or among children under 6 years. The seasonal pattern of child maltreatment coincided with the two school examination periods. The annual child maltreatment hospitalisation rate in Hong Kong in 2010 was 73.4 per 100 000 children under 19 years, more than double that in 2001. A peculiar seasonal pattern and an alarming increasing trend in child maltreatment hospitalisation were observed in Hong Kong, which we speculated to be related to school examination stress and increasing socioeconomic disparity. Our findings highlighted differences in the trends of child maltreatment between Hong Kong and the West. Professionals and policymakers should be made aware of these trends and develop effective strategies to tackle child maltreatment. Published by the BMJ Publishing Group Limited.

    2014-11-01

    Age-period-cohort (APC) analysis can inform registry-based studies of cancer incidence and mortality, but concerns about statistical identifiability and interpretability, as well as the learning curves of statistical software packages, have limited its uptake. We implemented a panel of easy-to-interpret estimable APC functions and corresponding Wald tests in R code that can be accessed through a user-friendly Web tool. Input data for the Web tool consist of age-specific numbers of events and person-years over time, in the form of a rate matrix of paired columns. Output functions include model-based estimators of cross-sectional and longitudinal age-specific rates, period and cohort rate ratios that incorporate the overall annual percentage change (net drift), and estimators of the age-specific annual percentage change (local drifts). The Web tool includes built-in examples for teaching and demonstration. User data can be input from a Microsoft Excel worksheet or by uploading a comma-separated-value file. Model outputs can be saved in a variety of formats, including R and Excel. APC methodology can now be carried out through a freely available user-friendly Web tool. The tool can be accessed at http://analysistools.nci.nih.gov/apc/. The Web tool can help cancer surveillance researchers make important discoveries about emerging cancer trends and patterns. ©2014 American Association for Cancer Research.

    The single intradermal comparative cervical tuberculin (SICCT) test is the primary test used for surveillance for bovine tuberculosis (bTB) in cattle in Great Britain (GB). The tuberculin used can, with other factors, influence test accuracy. In this analysis, the detection of infected cattle in GB 2005-2009 was compared between SICCT tests using tuberculins manufacturered by different manufacturers. Higher rates of reactors (adjusted rate 209 vs 186 per 100,000 tests, P = 0.003) and herd bTB incidents (adjusted total breakdown rate 5.1 vs 4.5 per 100 herd-years at risk, P manufactured at Weybridge compared with Lelystad. However, confirmation of infection in reactors by postmortem evidence was higher with Lelystad tuberculin (adjusted percent 44.1 vs 47.1, P = 0.018). The findings, overall, suggest slightly higher test sensitivity and lower test specificity associated with Weybridge tuberculin compared with Lelystad. Assuming effective adjustment for confounding, the overall impact of tuberculin manufacturing source (2007-2009), was calculated to range somewhere between 315 false positive breakdowns, and 1086 bTB breakdowns missed (624 confirmed) as a result of using Weybridge and Lelystad tuberculin, respectively. However, animals that tested negative to the SICCT were not slaughtered at the time of the tests, so definitive conclusions are not possible.

    In areas with relatively high iodine intake, the incidence rate of hypothyroidism is several-fold higher than that of hyperthyroidism. Recently, we found a similarly high prevalence rate of subclinical hypothyroidism compared with hyperthyroidism in a high iodine intake area, while a relatively low...... prevalence of subclinical hypothyroidism was observed in a low iodine intake area. In the present study we compared the incidence rate (newly diagnosed in primary care and at hospital) of overt hypothyroidism with that of hyperthyroidism in a well-defined geographical area in Jutland, Denmark, with an iodine...... intake around 60 microg/day. The number of personsxyears studied was 569,108. Data on hyperthyroidism have been published previously. The overall incidence of hypothyroidism was 13.5/100,000 per year (F/M 22.9/3.6), hyperthyroidism 38.7/100.000 per year (F/M 63.0/13.0). The incidence of hypothyroidism...

    Atherosclerotic cardiovascular disease (ASCVD) remains the leading cause of morbidity and mortality in most countries. Modification of common risk factors such as dyslipidaemia can result in significant reduction of ASCVD incidence in the population and improve clinical outcomes. The purpose of this review is to discuss and compare the latest worldwide lipid guidelines, and to demonstrate the variation in practice in different parts of the world. The lipid guidelines have recently been updated in different countries. The National Institute for Health and Care Excellence (NICE) guidelines in the United Kingdom were issued in July 2014, are risk based and are broadly similar to the American College of Cardiology/American Heart Association task force guidelines that were published in November 2013. Both these guidelines are in variance with both the Canadian Guidelines and the European Society of Cardiology/European Atherosclerosis Society guidelines 2011, which are target based and have different risk scoring systems, which results in significant variation in practice and increased healthcare costs in certain countries. The difference in guidelines in different countries makes it difficult for the clinician to standardize the treatment provided to individuals. The variance in risk scoring systems makes it difficult to compare risk prediction tools across countries and hence the optimum treatment available for a given population. Standardization of guidelines based on randomized controlled trial data and validation and calibration of various risk scoring systems could help improve clinical outcomes in this high-risk group of individuals at risk of ASCVD within individual countries.

    Although many case-control studies have suggested positive associations between carbohydrate intake and breast cancer incidence rates in both pre- and postmenopausal women, there is limited information available from cohort studies. We examined the effect of the intake of different carbohydrates, the glycemic index, and the glycemic load on breast cancer incidence in postmenopausal women taking into consideration tumor estrogen receptor status. Postmenopausal women (n = 23,870; aged 50-65 y) participated in the "Diet, Cancer, and Health" study, and provided information about diet and established risk factors for breast cancer. During follow-up, we identified 634 incidents of breast cancer. Associations between carbohydrate intake and breast cancer incidence were analyzed using Cox's regression models. There was no association for intake of glucose, fructose, sucrose, maltose, lactose, or starch and breast cancer incidence rate, and no association for glycemic index or glycemic load after adjusting for confounding factors. Intake of different carbohydrates was not associated with breast cancer incidence rates for either estrogen receptor positive (ER+) or (ER-) breast cancer. Similarly, glycemic index and glycemic load were not associated with ER+ breast cancer after adjusting for confounding factors. A borderline significant positive association between glycemic index and (ER-) breast cancer was observed (P = 0.05). In conclusion, we found no clear associations between intake of different carbohydrates, total carbohydrate intake, glycemic index, or glycemic load and breast cancer incidence in postmenopausal women. Furthermore, when ER+ and ER- breast cancer cases were analyzed separately, no clear associations were observed.

    Despite intensive research, the evidence for a protective effect of fruits and vegetables on breast cancer risk remains inconclusive. Other risk factors for breast cancer seem to vary with the estrogen receptor status of the breast tumor, and it is thus possible that the inconsistent results regarding a preventive effect of fruits and vegetables are due to lack of controlling for estrogen receptor status. The objective of this study was to investigate the effect of fruit and vegetable intake on postmenopausal breast cancer and explore whether the estrogen receptor status of the tumor modifies this relation. Postmenopausal women (n = 23,798; aged 50-64 y) provided information about diet and established risk factors for breast cancer in the cohort "Diet, Cancer and Health." During follow-up, 425 cases were diagnosed with breast cancer. Associations between intake of fruits and vegetables and the breast cancer rate were analyzed using Cox's regression model. The association for all breast cancers was an incidence rate ratio (IRR) of 1.02 (95% CI, 0.98-1.06) per 100 g/d increment of total intake of fruits, vegetables and juice. For estrogen receptor-positive (ER(+)) breast cancer, a borderline significant increase in the rate was seen, IRR: 1.05 (95% CI, 1.00-1.10), whereas a preventive effect was seen for estrogen receptor-negative (ER(-)) breast cancers, IRR: 0.90 (95% CI, 0.81-0.99). In conclusion, we did not find the overall breast cancer rate to be associated with the intake of fruits and vegetables, but there seemed to be different effects for ER(+) and ER(-) breast cancer.

    2012-04-01

    It has been suggested that fluoride in drinking water may increase the risk of osteosarcoma in children and adolescents, although the evidence is inconclusive. We investigated the association between community water fluoridation (CWF) and osteosarcoma in childhood and adolescence in the continental U.S. We used the cumulative osteosarcoma incidence rate data from the CDC Wonder database for 1999-2006, categorized by age group, sex and states. States were categorized as low (≤30%) or high (≥85%) according to the percentage of the population receiving CWF between 1992 and 2006. Confidence intervals for the incidence rates were calculated using the Gamma distribution and the incidence rates were compared between groups using Poisson regression models. We found no sex-specific statistical differences in the national incidence rates in the younger groups (5-9, 10-14), although 15-19 males were at higher risk to osteosarcoma than females in the same age group (pfluoridation status. We also compared sex and age specific osteosarcoma incidence rates cumulated from 1973 to 2007 from the SEER 9 Cancer Registries for single age groups from 5 to 19. There were no statistical differences between sexes for 5-14 year old children although incidence rates for single age groups for 15-19 year old males were significantly higher than for females. Our ecological analysis suggests that the water fluoridation status in the continental U.S. has no influence on osteosarcoma incidence rates during childhood and adolescence.

    2013-01-01

    The objective of this study was to compare the incidence rate of clinical mastitis (IRCM) between cows classified as high, average, or low for antibody-mediated immune responses (AMIR) and cell-mediated immune responses (CMIR). In collaboration with the Canadian Bovine Mastitis Research Network, 458 lactating Holsteins from 41 herds were immunized with a type 1 and a type 2 test antigen to stimulate adaptive immune responses. A delayed-type hypersensitivity test to the type 1 test antigen was used as an indicator of CMIR, and serum antibody of the IgG1 isotype to the type 2 test antigen was used for AMIR determination. By using estimated breeding values for these traits, cows were classified as high, average, or low responders. The IRCM was calculated as the number of cases of mastitis experienced over the total time at risk throughout the 2-year study period. High-AMIR cows had an IRCM of 17.1 cases per 100 cow-years, which was significantly lower than average and low responders, with 27.9 and 30.7 cases per 100 cow-years, respectively. Low-AMIR cows tended to have the most severe mastitis. No differences in the IRCM were noted when cows were classified based on CMIR, likely due to the extracellular nature of mastitis-causing pathogens. The results of this study demonstrate the desirability of breeding dairy cattle for enhanced immune responses to decrease the incidence and severity of mastitis in the Canadian dairy industry.

    To analyse the association of neighbourhood unemployment with incident self-reported physician-diagnosed Type 2 diabetes in a population aged 45-74 years from five German regions. Study participants were linked via their addresses at baseline to particular neighbourhoods. Individual-level data from five population-based studies were pooled and combined with contextual data on neighbourhood unemployment. Type 2 diabetes was assessed according to a self-reported physician diagnosis of diabetes. We estimated proportional hazard models (Weibull distribution) in order to obtain hazard ratios and 95% CIs of Type 2 diabetes mellitus, taking into account interval-censoring and clustering. We included 7250 participants residing in 228 inner city neighbourhoods in five German regions in our analysis. The incidence rate was 12.6 per 1000 person-years (95% CI 11.4-13.8). The risk of Type 2 diabetes mellitus was higher in men [hazard ratio 1.79 (95% CI 1.47-2.18)] than in women and higher in people with a low education level [hazard ratio 1.55 (95% CI 1.18-2.02)] than in those with a high education level. Independently of individual-level characteristics, we found a higher risk of Type 2 diabetes mellitus in neighbourhoods with high levels of unemployment [quintile 5; hazard ratio 1.72 (95% CI 1.23-2.42)] than in neighbourhoods with low unemployment (quintile 1). Low education level and high neighbourhood unemployment were independently associated with an elevated risk of Type 2 diabetes mellitus. Studies examining the impact of the residential environment on Type 2 diabetes mellitus will provide knowledge that is essential for the identification of high-risk populations. © 2014 The Authors.

    2014-01-01

    Background Repeated exposure to peritoneal dialysis (PD) solutions contributes to cumulative intraperitoneal inflammation and peritoneal injury. The present study aimed to explore the capacity of dialysate interleukin-6(IL-6) to a) predict peritoneal membrane function and peritonitis in incident PD patients, and b) to evaluate the influence of neutral pH, low glucose degradation product (GDP) PD solution on dialysate IL-6 levels. Methods The study included 88 incident participants from the balANZ trial who had completed 24-months of follow-up. Change in peritoneal solute transport rate (PSTR) and peritonitis were primary outcome measures, and the utility of IL-6 and IL-6 appearance rate (IL-6 AR) in predicting these outcomes was analyzed using multilevel linear regression and Cox proportional hazards models, respectively. Sensitivity analyses were performed by analyzing outcomes in a peritonitis-free cohort (n = 56). Results Dialysate IL-6 concentration significantly increased from baseline to 24 months (mean difference 19.07 pg/mL; P < 0.001) but was not affected by the type of PD solution received (P = 0.68). An increase in PSTR from baseline was associated with higher levels of IL-6 (P = 0.004), the use of standard solutions (P = 0.005) and longer PD duration (P < 0.001). Baseline IL-6 level was not associated with a shorter time to first peritonitis (adjusted hazard ratio 1.00, 95% CI 0.99-1.00, P = 0.74). Analysis of IL-6 AR as well as sensitivity analyses in a peritonitis-free cohort yielded comparable results. Conclusion Dialysate IL-6 concentration increased with longer PD duration and was a significant, independent predictor of PSTR. The use of biocompatible PD solutions exerted no significant effect on dialysate IL-6 levels but did abrogate the increase in PSTR associated with standard PD solutions. This is the first study to examine the impact of biocompatible solutions on the utility of IL-6 in predicting PSTR and peritonitis. PMID:24410736

    Genetic analysis of hereditary deafness (HD) has been performed in the city of Kirov and ten rural districts of Kirov oblast (administrative region). The analysis employed the methods used in audiology, medical genetic counseling, and DNA diagnosis. Deafness has been established to be hereditary in 143 children from 100 unrelated families. The incidence rates of isolated and syndromic HDs in the period studied (1995-2001) have been estimated at 1.25 and 0.36 per 1000 newborns, respectively, the total incidence rate of all HD forms being 1.61 per 1000 newborns (1 case per 621 newborns). DNA analysis for the detection of seven frequent mutations in the genes GJB2 (the 35delG, 167delT, 235delC, and M34T mutations), GJB6 (the del(GJB6-D13S1854) and del(GJB6-D13S1830) mutations), and TMC1 (the R34X mutation) has been performed in families with isolated neurosensory deafness. Molecular genetic analysis has detected mutations in 51 children (48.6%); in 54 children (51.4%), no mutations have been found. The following genotypes have been identified in children with HD: 35delG/35delG in 32 probands (30.5%), 35delG/+ in 16 probands (15.2%), 35delG/235delC in 1 proband (0.95%), M34T/+ in 1 proband (0.95%), and M34T/35delG in 1 proband (0.95%). The 167delT mutation has not been found. The frequency of the 35delG mutation in the GJB2 gene has been estimated to be 39.05%. In the group with a family history of HD, mutations have been found in 66.7% of patients; in the group without a family history of HD, in 37.5% of patients. No mutation has been found in the GJB6 or TMC1 gene. Molecular genetic analysis has been performed in a family with clinically diagnosed Treacher Collins-Franceschetti syndrome. Sequencing has been used to find the 748-69C>T polymorphism in intron 6 (in the homozygous state) and the 3635C>G mutation in exon 23 leading to the substitution of glycine for alanine at position 1176 of the amino acid sequence (Ala1176Gly, in the heterozygous state), which have not

    In this paper, we investigate the dynamics of a five-dimensional virus model incorporating saturation incidence rate, CTL immune response and three time delays which represent the latent period, virus production period and immune response delay, respectively. We begin this model by proving the positivity and boundedness of the solutions. Our model admits three possible equilibrium solutions, namely the infection-free equilibrium E0, the infectious equilibrium without immune response E1 and the infectious equilibrium with immune response E2. Moreover, by analyzing corresponding characteristic equations, the local stability of each of the feasible equilibria and the existence of Hopf bifurcation at the equilibrium point E2 are established, respectively. Further, by using fluctuation lemma and suitable Lyapunov functionals, it is shown that E0 is globally asymptotically stable when the basic reproductive numbers for viral infection R0 is less than unity. When the basic reproductive numbers for immune response R1 is less than unity and R0 is greater than unity, the equilibrium point E1 is globally asymptotically stable. Finally, some numerical simulations are carried out for illustrating the theoretical results.

    Full Text Available Abstract Background As malaria control efforts intensify, it is critical to monitor trends in disease burden and measure the impact of interventions. A key surveillance indicator is the incidence of malaria. Yet measurement of incidence is challenging. The slide positivity rate (SPR has been used as a surrogate measure of malaria incidence, but limited data exist on the relationship between SPR and the incidence of malaria. Methods A cohort of 690 children aged 1-10 years at enrollment were followed for all their health care needs over a four-year period in Kampala, Uganda. All children with fever underwent laboratory testing, allowing us to measure the incidence of malaria and non-malaria fevers. A formula was derived to estimate relative changes in the incidence of malaria (rΔIm based on changes in the SPR and the assumption that the incidence of non-malaria fevers was consistent over time. Observed and estimated values of rΔIm were compared over two, six, and 12 month time intervals after restricting the analysis to children contributing observation time between the ages of 4-10 years to control for aging of the cohort. Results Over the four-year observation period the incidence of malaria declined significantly from 0.93 episodes per person-year in 2005 to 0.39 episodes per person-year in 2008 (p Conclusion Changes in SPR provided a useful estimate of changes in the incidence of malaria in a well defined cohort; however, a gradual decline in the incidence of non-malaria fevers introduced some bias in these estimates.

    In Italy, Tubercolosis (TB) has increasingly become a disease for specific population subgroups such as immigrants. The objective of this paper is to describe the trend in TB incidence from 1999 to 2008 in Umbria: a low-incidence Italian region with high immigrants rates. Data were obtained from the Regional Information System for Infectious Diseases. Using a linear regressions model we estimated trends for number of cases and incidence rates; with a logistic regression model we estimated the effect of a set of covariates on the probability of being affected by TB. 590 TB cases were reported of whom 254 (43%) were foreign. In 2008 39.7 new cases per 100.000 were registered among foreign-born subjects. TB incidence among Italians was 3.8/100.000 Italians. But a linear regression analysis showed a statistically significant decreasing trend in the notification rate among foreign-born people (coef: -7.32, r2:0.57, p foreign patients (OR = 0.72, CI = 0.48-1.07). Foreign unskilled workers report a higher probability to be affected by TB (OR = 19.05, CI = 6.01-60.4). Increasing immigration rates may affect TB epidemiology. The analysis of incidence trends is an important toolfor monitoring tuberculosis disease control and to identify specific sub-group at risk.

    Full Text Available Background: A performance target (PT for the incidence rate (IR of acute encephalitis syndrome (AES was not defined by the World Health Organization (WHO due to lack of data. There is no specific treatment for ~90% of the AES cases. Objectives: (1 To determine the IR of AES not having specific treatment (AESn in two countries, India and Nepal. (2 To suggest the PT. Subjects and Methods: This was a record-based study of the entire population of India and Nepal from 1978 to 2011. The WHO definition was used for inclusion of cases. Cases that had specific treatment were excluded. IR was calculated per 100,000 population per annum. Forecast IR was generated from 2010 to 2013 using time-series analysis. Results: There were 165,461 cases from 1978 to 2011, of which 125,030 cases were from India and 40,431 were from Nepal. The mean IR of India was 0.42 (s 0.24 and that of Nepal was 5.23 (s 3.03. IRs of 2010 and 2011 of India and that of 2011 of Nepal were closer to the mean IR rather than the forecast IR. IR of 2010 of Nepal was closer to the forecast IR. The forecast IR for India for 2012 was 0.49 (0.19-1.06, for 2013 was 0.42 (0.15-0.97 and for Nepal for both 2012 and 2013 was 5.62 (1.53-15.05. Conclusions: IRs were considerably different for India and Nepal. Using the current mean IR as PT for the next year was simple and practical. Using forecasting was complex and, less frequently, useful.

    Osteosarcoma, which is the most common primary bone tumor, occurs most frequently in adolescents, but there is a second incidence peak among individuals aged > 60 years. Most osteosarcoma epidemiology studies have been embedded in large analyses of all bone tumors or focused on cases occurring in adolescence. Detailed descriptions of osteosarcoma incidence and survival with direct comparisons among patients of all ages and ethnicities are not available. Frequency, incidence, and survival rates for 3482 patients with osteosarcoma from the National Cancer Institute's population-based Surveillance, Epidemiology, and End Results (SEER) Program between 1973 and 2004 were investigated by age (ages 0-24 years, 25-59 years, and 60 to > or = 85 years), race, sex, pathology subtype, stage, and anatomic site. There were large differences in incidence and survival rates by age. There was a high percentage of osteosarcoma with Paget disease and osteosarcoma as a second or later cancer among the elderly. There was a high percentage of osteosarcoma among patients with Paget disease and osteosarcoma as a second or later cancer among the elderly. Tumor site differences among age groups were noted. Survival rates varied by anatomic site and disease stage and did not improve significantly from 1984 to 2004. This comprehensive, population-based description of osteosarcoma, identified important differences in incidence, survival, pathologic subtype, and anatomic site among age groups, and quantified the impact of osteosarcoma in patients with Paget disease or as a second cancer on incidence and mortality rates. These findings may have implications in understanding osteosarcoma biology and epidemiology. (c) 2009 American Cancer Society

    Full Text Available Abstract Background Carpal tunnel syndrome (CTS is a socially relevant condition associated with biomechanical risk factors. We evaluated age-sex-specific incidence rates of in-hospital cases of CTS in central/northern Italy and explored relations with marital status. Methods Seven regions were considered (overall population, 14.9 million over 3–6-year periods between 1997 and 2002 (when out-of-hospital CTS surgery was extremely rare. Incidence rates of in-hospital cases of CTS were estimated based on 1 codified demographic, diagnostic and intervention data in obligatory discharge records from all Italian public/private hospitals, archived (according to residence on regional databases; 2 demographic general population data for each region. We compared (using the χscore test age-sex-specific rates between married, unmarried, divorced and widowed subsets of the general population. We calculated standardized incidence ratios (SIRs for married/unmarried men and women. Results Age-standardized incidence rates (per 100,000 person-years of in-hospital cases of CTS were 166 in women and 44 in men (106 overall. Married subjects of both sexes showed higher age-specific rates with respect to unmarried men/women. SIRs were calculated comparing married vs unmarried rates of both sexes: 1.59 (95% confidence interval [95% CI], 1.57–1.60 in women, and 1.42 (95% CI, 1.40–1.45 in men. As compared with married women/men, widows/widowers both showed 2–3-fold higher incidence peaks during the fourth decade of life (beyond 50 years of age, widowed subjects showed similar trends to unmarried counterparts. Conclusion This large population-based study illustrates distinct age-related trends in men and women, and also raises the question whether marital status could be associated with CTS in the general population.

Changes in SPR produced reasonably accurate estimates of rDeltaIm over all time intervals. The average absolute difference in observed and estimated values of rDeltaIm was lower for six-month intervals (0.13) than it was for two-month (0.21) or 12 month intervals (0.21). Changes in SPR provided a useful estimate of changes in the incidence of malaria in a well defined cohort; however, a gradual decline in the incidence of non-malaria fevers introduced some bias in these estimates.

    Full Text Available Introduction The aim of this study was to determine the incidence rates of endometrial hyperplasia (EH and endometrial cancer (EC in the Republic of Korea using national insurance claim data generated from 2009 to 2012. Materials and Methods Data that were generated from 2009 to 2012 were sourced from the Korean Health Insurance Review and Assessment Service-National Inpatients Sample database. The data from women who were assigned diagnosis codes representing EH or EC within 1 month of being assigned codes that corresponded to procedures that included endometrial biopsies and several types of gynecologic surgeries to obtain endometrial pathology samples, were selected for analysis. Results Data from 2,477,424 women were entered into the database between 2009 and 2012, and the data from 1,868 women with EH and 868 women with EC were extracted for analysis. The mean ages of the patients were 44.1 ± 0.4 years for those with EH and 52.7 ± 0.6 years for those with EC. The EH and EC incidence rates were 37 per 100,000 woman-years and 8 per 100,000 woman-years, respectively. The EH and EC incidence rates peaked when the women were in their late forties and fifties, respectively. Conclusions The EH and EC incidence rates determined in this study were somewhat lower than those determined from previous studies. Further studies are required that adjust the data for race, menopausal hormone therapy, and obesity.

    This study evaluates the annual incidence of syphilitic uveitis in the US and trends in hospital admissions over time. Retrospective, longitudinal incidence rate analysis of the National Inpatient Sample (NIS) data from 1998 to 2009. The NIS is a de-identified, random sample dataset of inpatient hospitalizations from 46 states. The number of cases of syphilitic uveitis was defined by (1) International Classification of Diseases, 9th Revision (ICD-9) code for syphilis and uveitis or (2) ICD-9 code for syphilitic uveitis. Annual case count, incidence rate, and trend over time were calculated. Multivariate logistic regression was used to evaluate associated factors for a syphilitic uveitis diagnosis. The study included 455 310 286 hospitalizations during a 12-year study period with a mean of 37 942 524 patients annually. Syphilis and uveitis was recorded for 1861 patients (155 annually) and syphilitic uveitis was diagnosed in 204 subjects (average of 17 cases annually). There was no change in the incidence of syphilitic uveitis, using either definition, over the study period (P for trend = .46). The mean annual incidence of syphilis and uveitis was 0.0004%, or 4 per million. Syphilitic uveitis had an annual incidence of 0.000045%, or 0.45 per million. The odds of syphilitic uveitis were lower among women (odds ratio [OR] 0.40, CI 0.28-0.57) and increased with comorbid acquired immunodeficiency syndrome (OR 4.52, CI 3.01-6.79). We report the first incidence of syphilitic uveitis in the United States. Fortunately, this remains a rare condition. The results demonstrate no change in the number of inpatient admissions for syphilitic uveitis during the study period. Copyright © 2017 Elsevier Inc. All rights reserved.

    Variation in end-stage renal disease treatment rates in the UK persist after adjustment for socio-demographic factors. UK-wide ecological study using population socio-demographic factors, health status characteristics and access to health services factor in to explain the incidence of renal replacement therapy (RRT). There was a 6% higher incidence rate of RRT per standard deviation (SD) increase in area diabetes prevalence after adjustment for area level socio-economic deprivation status and the proportion of non-white residents [incidence rate ratio adjusted (IRR adjusted) 1.06 (95% confidence interval 1.03,1.09), P RRT incidence rate was seen with each SD higher proportion of diabetics achieving an HbA1c of RRT incidence rate per SD increase [IRR adjusted 1.08 (1.04, 1.11), P RRT incidence rate [IRR adjusted 0.93 (0.91, 0.96), P RRT incidence rates [IRR adjusted 1.06 (1.03, 1.09), P RRT incidence, but mammography uptake was not associated. In total, 31% of the regional variation in RRT incidence could be explained by these factors. Diabetes prevalence, the proportion of diabetics achieving good glycaemic control, hypertension prevalence, life expectancy, premature CV mortality, CABG/angioplasty and knee replacement rates were all associated with RRT incidence. A third of the regional variation in RRT incidence between areas can be explained by these demographic, health and access to health services factors.

    Full Text Available Although antiretroviral therapy (ART is known to be associated with time-dependent reductions in tuberculosis (TB incidence, the long-term impact of ART on incidence remains imprecisely defined due to limited duration of follow-up and incomplete CD4 cell count recovery in existing studies. We determined TB incidence in a South African ART cohort with up to 8 years of follow-up and stratified rates according to CD4 cell count recovery. We compared these rates with those of HIV-uninfected individuals living in the same community.Prospectively collected clinical data on patients receiving ART in a community-based cohort in Cape Town were analysed. 1544 patients with a median follow-up of 5.0 years (IQR 2.4-5.8 were included in the analysis. 484 episodes of incident TB (73.6% culture-confirmed were diagnosed in 424 patients during 6506 person-years (PYs of follow-up. The TB incidence rate during the first year of ART was 12.4 (95% CI 10.8-14.4 cases/100PYs and decreased to 4.92 (95% CI 3.64-8.62 cases/100PYs between 5 and 8 years of ART. During person-time accrued within CD4 cell strata 0-100, 101-200, 201-300, 301-400, 401-500, 501-700 and ≥700 cells/µL, TB incidence rates (95% CI were 25.5 (21.6-30.3, 11.2 (9.4-13.5, 7.9 (6.4-9.7, 5.0 (3.9-6.6, 5.1 (3.8-6.8, 4.1 (3.1-5.4 and 2.7 (1.7-4.5 cases/100PYs, respectively. Overall, 75% (95% CI 70.9-78.8 of TB episodes were recurrent cases. Updated CD4 cell count and viral load measurements were independently associated with long-term TB risk. TB rates during person-time accrued in the highest CD4 cell count stratum (>700 cells/µL were 4.4-fold higher that the rate in HIV uninfected individuals living in the same community (2.7 versus 0.62 cases/100PYs; 95%CI 0.58-0.65.TB rates during long-term ART remained substantially greater than rates in the local HIV uninfected populations regardless of duration of ART or attainment of CD4 cell counts exceeding 700 cells/µL.

    This is one of few published population-based studies describing breed specific rates of canine primary bone tumors. Incidence rates related to dog breeds could help clarify the impact of etiological factors such as birth weight, growth rate, and adult body weight/height on development of these tumors. The study population consisted of dogs within 4 large/giant breeds; Irish wolfhound (IW), Leonberger (LB), Newfoundland (NF), and Labrador retriever (LR), born between January 1st 1989 and December 31st 1998. Questionnaires distributed to owners of randomly selected dogs — fulfilling the criteria of breed, year of birth, and registration in the Norwegian Kennel Club — constituted the basis for this retrospective, population-based survey. Of the 3748 questionnaires received by owners, 1915 were completed, giving a response rate of 51%. Forty-three dogs had been diagnosed with primary bone tumors, based upon clinical examination and x-rays. The breeds IW and LB, with 126 and 72 cases per 10 000 dog years at risk (DYAR), respectively, had significantly higher incidence rates of primary bone tumors than NF and LR (P dogs, like NF and LB, observed in this study. Defining these breed-specific incidence rates enables subsequent case control studies, ultimately aiming to identify specific etiological factors for developing primary bone tumors. PMID:22210997

    In general, it has been reported that rotavirus infection was detected year round in tropical countries. However, studies in Venezuela and Brazil suggest a seasonal behavior of the infection. On the other hand, some studies link infection with climatic variables such as rainfall. This study analyzes the pattern of behavior of the rotavirus infection in Carabobo-Venezuela (2001-2005), associates the seasonality of the infection with rainfall, and according to the seasonal pattern, estimates the age of greatest risk for infection. The analysis of the rotavirus temporal series and accumulated precipitation was performed with the software SPSS. The infection showed two periods: high incidence (November-April) and low incidence (May-October). Accumulated precipitation presents an opposite behavior. The highest frequency of events (73.8% 573/779) for those born in the period with a low incidence of the virus was recorded at an earlier age (mean age 6.5 +/- 2.0 months) when compared with those born in the station of high incidence (63.5% 568/870, mean age 11.7 +/- 2.2 months). Seasonality of the infection and the inverse relationship between virus incidence and rainfall was demonstrated. In addition, it was found that the period of birth determines the age and risk of infection. This information generated during the preaccine period will be helpful to measure the impact of the vaccine against the rotavirus.

    While studies demonstrated favorable outcomes of nocturnal home hemodialysis (NHHD), direct comparison on employment rate, clinical and laboratory outcomes between the NHHD and continuous ambulatory peritoneal dialysis (CAPD) had not been previously performed. A 1-year retrospective observation study was performed in 20 incidents alternate night NHHD and 81 incident CAPD patients of Chinese ethnicity, who were sex, diabetic status, and Charlson comorbidity index matched, but not age due to our center's age limit for NHHD enrollment. The primary outcome was the difference in employment rate at 1 year. Secondary outcomes included differences in clinical parameters (weight, blood pressure, number of antihypertensive medication, dosage of phosphate binders, and erythropoietin stimulating agent) and laboratory parameters (residual renal function, mineral metabolic markers, hemoglobin). NHHD subjects were 5 years younger than CAPD patients, and they had higher employment rate (80% vs. 33.3%, P < 0.01) at 1 year, with age-adjusted odds ratio for employment was 6.10 (95% confidence interval 1.77-20.99, P = 0.04). They consumed less aluminum-based phosphate binder (0 vs. 1800 mg, P < 0.01), but showed no significant disparities in other clinical parameters. Residual renal function in both groups declined comparably, nonetheless NHHD group had lower serum phosphate (1.37 vs. 1.71 mmol/L, P = 0.01) and calcium phosphate product (3.13 vs. 4.12 mmol(2) /L(2) , P < 0.01), with similar hemoglobin levels. NHHD appeared to offer higher employment rate, lower dosage of aluminum-based phosphate binder and mineral metabolic markers at 1 year compared with CAPD in Hong Kong. © 2017 International Society for Hemodialysis.

    IMPORTANCE Late-onset Alzheimer disease (LOAD), defined as onset of symptoms after age 65 years, is the most common form of dementia. Few reports investigate incidence rates in large family-based studies in which the participants were selected for family history of LOAD. OBJECTIVE To determine the incidence rates of dementia and LOAD in unaffected members in the National Institute on Aging Genetics Initiative for Late-Onset Alzheimer Disease/National Cell Repository for Alzheimer Disease (NIA-LOAD/NCRAD) and Estudio Familiar de Influencia Genetica en Alzheimer (EFIGA) family studies. DESIGN, SETTING, AND PARTICIPANTS Families with 2 or more affected siblings who had a clinical or pathological diagnosis of LOAD were recruited as a part of the NIA-LOAD/NCRAD Family Study. A cohort of Caribbean Hispanics with familial LOAD was recruited in a different study at the Taub Institute for Research on Alzheimer’s Disease and the Aging Brain in New York and from clinics in the Dominican Republic as part of the EFIGA study. MAIN OUTCOMES AND MEASURES Age-specific incidence rates of LOAD were estimated in the unaffected family members in the NIA-LOAD/NCRAD and EFIGA data sets. We restricted analyses to families with follow-up and complete phenotype information, including 396 NIA-LOAD/NCRAD and 242 EFIGA families. Among the 943 at-risk family members in the NIA-LOAD/NCRAD families, 126 (13.4%) developed dementia, of whom 109 (86.5%) met criteria for LOAD. Among 683 at-risk family members in the EFIGA families, 174 (25.5%) developed dementia during the study period, of whom 145 (83.3%) had LOAD. RESULTS The annual incidence rates of dementia and LOAD in the NIA-LOAD/NCRAD families per person-year were 0.03 and 0.03, respectively, in participants aged 65 to 74 years; 0.07 and 0.06, respectively, in those aged 75 to 84 years; and 0.08 and 0.07, respectively, in those 85 years or older. Incidence rates in the EFIGA families were slightly higher, at 0.03 and 0.02, 0.06 and 0.05, 0

    The expansion of the Surveillance, Epidemiology, and End Results (SEER) program and the determination of annual population estimates by county level for different racial/ethnic groups since 1990 allow the calculation of annual cancer incidence rates for Hispanics. Incidence rates were calculated for 11 SEER areas representing 25% of the Hispanic population. Standard regression analyses of log-transformed rates were used to determine the trends of the rates. An important measure of the cancer burden among Hispanics is the rank order of their cancers. For Hispanic males, the five major cancers (in declining order) are prostate, lung and bronchus, colon/rectum, non-Hodgkin lymphoma, and stomach cancers. For Hispanic females, the top five cancers are breast, colon/rectum, lung and bronchus, cervix, and endometrial cancers. Another measure of cancer burden is their rates relative to white non-Hispanics. Hispanic males have rates greater than white non-Hispanic males for stomach (1.6 times greater) and liver and IBD cancers (2.2), whereas Hispanic females have greater rates for cervix (2.2 times greater), liver and IBD (2.0), stomach (2.1), and gallbladder cancers (3.3). Other measures of cancer burden include the trends in Hispanic rates. Hispanic males have significant declining trends for all sites, prostate cancer, and urinary bladder cancer, and an increasing trend for liver and IBD cancers. Hispanic females have significant declining trends for cervix and urinary bladder cancers. The SEER cancer incidence rates and trends provide a general overview of the cancer burden among Hispanics residing in the SEER sites. This type of information is critical for determining interventions to reduce the cancer burden among Hispanics in the United States. Copyright 2000 American Cancer Society.

    Full Text Available Due to the relatively high prevalence of hypotension (20% -40% after spinal anesthesia as well as the adverse effects of hypotension on mother and baby, it is better to prevent hypotension as much as possible. Therefore, this study is aimed to determine the relationship between postural blood pressure and heart rate changes and hypotension incidence rate after spinal anesthesia in cesarean section.63 women aging18 to 45years old with fullterm pregnancy, who were candidate for caesarean section with spinal anesthesia, entered the study. Afterwards, the diastolic, systolic, and mean arterial pressures as well as the heart rate (pulse in different positions (sitting, lying, and left lateral were measured. After spinal anesthesia, the patients' blood pressure was measured and recorded every minute until the10thmin, then every 3 minute until the15thmin, and then every 5 minute until the end of cesarean section. Data analysis was performed using SPSS (ver. 19 software, descriptive statistics, one-way ANOVA, and post hoc Bonferroni test. In this study, the hypotension incidence rate was 30% and the orthostatic variation rate of the systolic blood pressure in more than half of the people was between 4.39 to 13.49psi, which showed the highest variation compared to the diastolic pressure, mean arterial blood pressure (or: mean arterial pressure [MAP], and heart(pulse. Considering the correlation coefficient of 0.27, the systolic blood pressure in the lateral position has the highest relationship with the incidence of hypotension. The postural systolic blood pressure changes in patients prior to the spinal anesthesia can be a predictive factor for the post-spinal hypotension incidence.

    Given that sympathetic tone is associated with hypertension, we sought to determine whether resting heart rate (RHR), as a surrogate for cardiac autonomic function, was associated with incident hypertension. We analyzed 21,873 individuals without a history of hypertension who underwent a clinically indicated exercise stress test. Baseline RHR was assessed prior to testing and was categorized as 85 beats-per-minute (bpm). Incident hypertension was defined by subsequent diagnosis codes for new-onset hypertension from three or more encounters. We tested for effect modification by age (85 bpm) were younger, more likely to be female, heavier, diabetic, and achieve lower metabolic equivalents (METS). Over a median of 4 years follow-up, there were 8,179 cases of incident hypertension. Compared to RHR 85 bpm had increased risk of hypertension after adjustment for CHD risk factors, baseline blood pressure (BP), and METS (hazard ratio = 1.15 (95% confidence interval 1.08-1.23)). Age was an effect modifier (interaction P = 0.02), whereas sex, race, and CHD were not. In age-stratified analyses the relationship remained significant only in those younger than 60 years. Elevated RHR is an independent risk factor for incident hypertension, particularly in younger persons. Whether lifestyle modification or other strategies to reduce RHR can prevent incident hypertension in high-risk individuals warrants further study. © American Journal of Hypertension, Ltd 2015.

    Mobile phone use in the United Kingdom and other countries has risen steeply since the early 1990's when the first digital mobile phones were introduced. There is an ongoing controversy about whether radio frequency (RF) exposure from mobile phones increases the risk of brain cancer. However, given the widespread use and nearly two decades elapsing since mobile phones were introduced, an association should have produced a noticeable increase in the incidence of brain cancer by now. Trends in rates of newly diagnosed brain cancer cases in England between 1998 and 2007 were examined. There were no time trends in overall incidence of brain cancers for either gender, or any specific age group. Systematic increases in rates for cancers of the temporal lobe in men (0.04 new cases/year) and women (0.02/year) were observed, along with decreases in the rates of cancers of the parietal lobe (-0.03/year), cerebrum (-0.02/year) and cerebellum (-0.01/year) in men only. The increased use of mobile phones between 1985 and 2003 has not led to a noticeable change in the incidence of brain cancer in England between 1998 and 2007. The observed increase in the rate of cancers in the temporal lobe, if caused by mobile phone use, would constitute phones. Copyright © 2011 Wiley-Liss, Inc.

    Sarcopenia is a degenerative syndrome mainly characterized by the atrophy of skeletal muscle, along with the decrease of muscle strength and function. However, there are currently few studies concerning sarcopenia in patients undergoing maintenance hemodialysis dialysis (MHD). This study was aimed to investigate the incidence of sarcopenia in MHD patients and its influencing factors, as well as its impact on survival risk. All 131 MHD patients enrolled in our study were tested with bioelectrical impedance analysis (BIA) and grip strength. Demographic data was collected and anthropometric measurement and laboratory examination were conducted. The total incidence of sarcopenia within the 131 MHD patients was 13.7% and the incidence of sarcopenia in patients over 60 years was 33.3%. The dialysis duration, with or without diabetes, serum phosphorus and pre-albumin levels of sarcopenic patients were significantly different from those of non-sarcopenicones; the modified quantitative subjective global assessment (MQSGA) scores of sarcopenic patients were higher than those without sarcopenia. Multivariate analysis showed that dialysis duration, diabetes and serum phosphorus level were independent risk factors for sarcopenia in MHD patients. Kaplan-Meier survival analysis showed a one-year survival of 88.9% in sarcopenic patients, which was significantly lower than non-sarcopenic patients. The incidence of sarcopenia in MHD patients was high and increased gradually with age. Dialysis duration, diabetes, serum phosphorus level and malnutrition predisposed the patients to sarcopenia. One-year follow-up found that the mortality risk of sarcopenic patients was higher than that of non-sarcopenic patients.

    Full Text Available Abstract Background The magnitude of socioeconomic differences in health varies between societies, and over time within a given society. We studied the association between social class and incidence of cancers of the gastro-intestinal tract over time in a large cohort in Finland. Methods We studied social class variation among 45–69 year-old Finns during 1971–95 in incidence of cancers of the gastro-intestinal tract by means of a computerized record linkage of the Finnish Cancer Registry and the 1970 Population Census, which included social class data. Results There were 2.3 million individuals in the cohort under follow-up, with 1622 cases of cancer of the esophagus, 8069 stomach (non-cardia, 1116 cardia, 408 small intestine, 6361 colon, 5274 rectum, 1616 liver, 1756 gallbladder, and 5084 pancreas during 1971–1995. Cancers of the esophagus, stomach, cardia, gallbladder and pancreas were most common among persons belonging to a low social class. Cancers of the small intestine in males only, colon in both genders, and rectum in females were most common in the higher social classes. Incidence of stomach cancer decreased and incidence of colon cancer increased over time in both genders in all social classes, and the large differences between social classes remained unchanged over time. Incidence rates of cardia cancer did not change substantially over time. Conclusion There is a large variation in incidence of cancer of the gastrointestinal tract by social class in Finland. Although much of the observed social class differences probably could be explained by known etiological factors such as diet, physical exercise, alcohol consumption, smoking and exogenous hormone use, part of the variation is apparently attributable to largely unknown factors.

    Coronary event rates have declined in most Western countries during the past decades, but the trends in the former Eastern block have not been established. The purpose of the present study was to examine the trends in acute coronary events during 1991-2005 in Tallinn, Estonia. The Tallinn Acute Myocardial Infarction (AMI) Registry recorded all AMI events among the residents of Tallinn, Estonia, aged 35-64 years during two time periods, 1991-1997 and 2003-2005. Altogether, 4889 AMI events were recorded. The average age-standardized incidence and attack rate of AMI events were lower in the second than in the first registration period in both sexes. When analyzed annually, the AMI event rates increased from 1991 to 1993 in both sexes. Thereafter from 1993 to 2005 the incidence of first AMI events declined significantly, 2.7%/year in men and 5.0%/year in women (P Estonia. After that especially the incidence of first AMI started to decline, and the declines have continued until 2005.

    Mines are hazardous and workers can suffer many types of accidents caused by fire, flood, explosion or collapse. Injury incidence rates in mining are considerably higher than those registered by other economic sectors. One of the main reasons for this high-level incidence rate is the existence of a large number of dangerous workplaces. This work analyzes the influence that occupational safety management had on the accidents that took place in Spanish mining of industrial and ornamental stone during the period 2007-2008. Primary data sources are: (a) Results from a statistical study of the occupational health and safety management practices of 71 quarries defined by a questionnaire of 41 items; and (b) Occupational accidents registered in the Spanish industrial and ornamental stone mining throughout the period 2007-2008. The obtained results indicate that workplaces with a low average score in the analysis of occupational safety management have a higher incidence rate of accidents. Studies on mining workplaces are very important to help detect occupational safety concerns. Results from this study help raise awareness and will encourage the adoption of appropriate measures to improve safety.

    Recent trends in incidence rates for tobacco-related cancers may vary geographically because of variation in socioeconomic status and in history of comprehensive state tobacco control programs (starting with California in 1989). Recent trends in risk factors are likely to affect cancer incidence rates at the youngest ages Trends in age-adjusted incidence rates for cancers most strongly associated with tobacco (ie, lung, oral cavity-pharynx, and bladder cancers) were analyzed for 1992 through 2004 in 11 areas (the states of Connecticut, Hawaii, Iowa, Utah, and New Mexico, and the metropolitan areas of Atlanta, Georgia; Detroit, Michigan; Los Angeles County, California; San Francisco-Oakland, California; San Jose-Monterey, California; and Seattle-Puget Sound, Washington) in the Surveillance, Epidemiology and End Results (SEER) Program. The 8 states differed in poverty rate of the population and in history of statewide tobacco control efforts as measured by an initial outcomes index (IOI) for the 1990s and a strength of tobacco control (SoTC) index for 1999 through 2000. Annual percentage change (APC) in incidence rate was calculated for whites and blacks separately and by sex for each SEER area. Among whites, the largest declines for lung cancer were in the 3 SEER areas of California, which were the only areas with significant (negative) APCs for oral cavity-pharynx cancer (but not for bladder cancer). For blacks, significant (negative) APCs for both lung and oral cavity-pharynx cancers were found in 4 of 5 areas with useful data but only 1 of 3 areas for bladder cancer. The strongest correlations of APCs for whites were for lung and oral cavity-pharynx cancers with the IOIs for the early 1990s and with the SoTC (due to the influence of California, which had the highest SoTC). Lung and oral cavity-pharynx cancer incidence rates among whites aged 15 to 54 years declined more in California than in other areas, possibly because of comprehensive state tobacco control

    Full Text Available Background: The data collected by sanitary-epidemiological stations in 2005–2014 were analyzed to determine the incidence rates of borreliosis Lyme disease in the West Pomerania group of workers exposed to tick bites. Material and Methods: It was assumed that an adequate comparison of official epidemiological data with the data concerning the number of exposed people, is an indispensable condition for assessing properly the trend in Lyme disease incidence rates, concerning at the same time a real scale of occupational exposure. The study covered a selected group of forestry workers, i.e., white-collar staff employed in different units of the State Forests National Forest Holding with their seats in West Pomerania. The aim of the research was to process and analyze the data on workers employed in the forest sector and their positions, requested from district sanitary-epidemiological stations. Results: In the years concerned 282 cases of the occupational disease were recorded mainly in the groups of forest rangers, junior foresters and forest service inspectors. The values of the incidence factor exhibit high variability with the major share of cases recorded in the years 2008–2010 that accounted for 61.8% of the total occurrences concerned. The incidence in the years 2008, 2009 and 2010 amounted to 2418, 2828 and 2646 cases per 100 000 employees, respectively. Conclusions: The results show that previously published information about the incidence of Lyme disease in the agriculture, forestry and hunting sector, did not fully illustrate a real scale of occupational risk.

The incidence in the years 2008, 2009 and 2010 amounted to 2418, 2828 and 2646 cases per 100 000 employees, respectively. The results show that previously published information about the incidence of Lyme disease in the agriculture, forestry and hunting sector, did not fully illustrate a real scale of occupational risk.

    Full Text Available Background: The monitoring of the lung malignant neoplasms incidence provides reliable data (particularly to medical and administrative services in order that they could work out and undertake current and a long-term decisions concerning with organisation of fight against cancer (including costs of cancer treatment, investments in oncology, anticancer education, etc.. But existing need most rationally resolves in a struggle with lung cancer (and other cancer. Therefore an attempts looking for the endemic areas with a long-lasting appear the biggest and smallest lung cancer incidence rates in the Silesia population. It is aim of this work. Materials and methods: The monitoring of the malignant neoplasm ills, among others of the lung cancer, is based on obligatory procedure of reporting them on a form MZN1a (from 1962 year. After verifications used in this work – 27 796 cases total for males and females suffering for the lung cancer within Silesia voivodeship in the years 1999-2009. Age-specific (for 5-year age groups, crude and age-standardized rates (with the use direct method by M. Spiegelman and with the use of the age-structure of “world population” (by R. Doll – were calculated. Comparisons of rate values (between endemic areas made of the use O.S. Miettinen and P. Katz procedures. Results: Silesia voivodeship it is the region of high risk lung cancer incidence in comparison to other ones in Poland. Lung cancer incidence among women is – in comparison to men – lower. But, just as among men – it is strongly differentiated according to counties. However, in comparison two periods – 1999-2002 : 2006-2009 – standardized incidence rates among females have been increasing from 14.0/100 thousands to 15.6/100ths, i.e. about 11.5%, and among males have been decreasing distinctly: from 66.9/100ths to 53.6/100ths, i.e. about 20%. The biggest frequency of ill (statistically significant high caused by the lung cancer among men concern

    Our aims were to determine acute myocardial infarction (AMI) incidence and mortality rates, and population and in-hospital case-fatality in the population older than 74 years; variability in clinical characteristics and AMI management of hospitalized patients, and changes in the incidence and mortality rates, case-fatality, and management by age groups from 1996 to 1997 and 2007 to 2008. A population-based AMI registry in Girona (Catalonia, Spain) including individuals with suspected AMI older than 34 years. The incidence rate increased with age from 169 and 28 cases/100 000 per year in the group aged 35 to 64 years to 2306 and 1384 cases/100 000 per year in the group aged 85 to 94 years, in men and women, respectively. Population case-fatality also increased with age, from 19% in the group aged 35 to 64 years to 84% in the group aged 85 to 94 years. A lower population case-fatality was observed in the second period, mainly explained by a lower in-hospital case-fatality. The use of invasive procedures and effective drugs decreased with age but increased in the second period in all ages up to 84 years. Acute myocardial infarction incidence, mortality, and case-fatality increased exponentially with age. There is still a gap in the use of invasive procedures and effective drugs between younger and older patients. Copyright © 2017 Sociedad Española de Cardiología. Published by Elsevier España, S.L.U.

    Background There is a lack of reliable epidemiological data on longitudinal trends in stroke attack rates, incidence, and mortality in the countries of the Baltic region. Aims The aim of the present study was to explore the longitudinal trends of stroke in middle-aged urban population of Lithuania during the period of 1986 through 2012. Methods All stroke events in the studied population were ascertained and validated according to the standardized criteria outlined by the WHO MONICA Project. The study included all patients in Kaunas (Lithuania) city aged 25 to 64 years who experienced a stroke between 1986 and 2012. Estimates of time-trends of the annual percentage change in stroke attack rates, incidence of stroke, and mortality from this condition were made by applying the Joinpoint regression analysis. Results During the study period, 9,992 stroke events were registered. The overall proportion of recurrent events was 25.7%. Overall, 18.9% of the events (20.0% in men, and 17.4% in women) were fatal within 28 days. During the period of 1986 to 2012, a flat trend in the incidence of stroke was observed among both male and female middle-aged inhabitants of Kaunas city, while attack rates were increasing due to the increase in recurrent strokes. Both mortality and 28-day case fatality of stroke declined significantly over the study period in both sexes. Conclusions An increase both in the incidence and recurrence of stroke among middle-aged men residing in Kaunas city and in the recurrence of stroke among women denotes the inefficiency of measures applied both for primary and secondary prevention of stroke in Lithuania. The revision of current prevention strategies and the introduction of new ones are of paramount importance in order to fight the epidemic of stroke. PMID:27124412

    Full Text Available Objective: To evaluate the concomitant systemic diseases with postmenopausal osteoporosis and to investigate the points to be considered in treatment approach of patients with osteoporosis. Materials and Methods: The study included 110 female patients admitted to our clinic and followed up after postmenopausal osteoporosis diagnosis. Besides the demographic data; the concomitant diseases of the patients such as hypertension, hypo-hyperthyroidism, diabetes mellitus, Alzheimer’s disease, malignancy, osteoarthritis, gastrointestinal system diseases, chronic obstructive pulmonary disease (COPD- asthma and depression were also recorded. Results: The mean age of the patients included in our study was 65.9±9.8 years. When the concomitant systemic diseases were examined; 40 patients had hypertension, 32 patients had osteoarthritis, 24 patients had gastrointestinal tract problems, 22 patients had thyroid disease, 21 patients had depression, 15 patients had hyperlipidemia, 12 patients had diabetes mellitus, 10 patients had COPD - asthma, 7 patients had cardiac diseases, 5 patients had malignancy and 2 patients had Alzheimer disease. Conclusion: Osteoporosis is a common disease in the geriatric population. As a chronic disease with an increasing incidence with aging; it can cause many health problems, prevalently pathological bone fractures, in our country and all over the world. Constitutively, prophylaxis of osteoporosis should be the first step. Because systemic diseases with increasing incidence with aging may affect the severity of osteoporosis and impair the treatment; it is important for both clinicians and the society to have sufficient information about osteoporosis.

    The issue of whether cell phone usage can contribute toward the development of brain tumors has recently been reignited with the International Agency for Research on Cancer classifying radiofrequency electromagnetic fields as 'possibly' carcinogenic to humans in a WHO report. To our knowledge, this is the largest study reporting on the incidence and mortality of malignant brain tumors after long-term use of the cell phone by more than 23 million users. A population-based study was carried out the numbers of cell phone users were collected from the official statistics provided by the National Communication Commission. According to National Cancer Registry, there were 4 incidences and 4 deaths due to malignant neoplasms in Taiwan during the period 2000-2009. The 10 years of observational data show that the intensive user rate of cell phones has had no significant effect on the incidence rate or on the mortality of malignant brain tumors in Taiwan. In conclusion, we do not detect any correlation between the morbidity/mortality of malignant brain tumors and cell phone use in Taiwan. We thus urge international agencies to publish only confirmatory reports with more applicable conclusions in public. This will help spare the public from unnecessary worries.

    2006-04-01

    Full Text Available Human immunodeficiency virus (HIV is the worldwide disseminated causative agent of acquired immunodeficiency syndrome (AIDS. HIV is a member of the Lentivirus genus of Retroviridae family and is grouped in two types named HIV-1 and HIV-2. These viruses have a notable ability to mutate and adapt to the new conditions of human environment. A large incidence of errors at the transcriptional level results in changes on the genetic bases during the reproductive cycle. The elevated genomic variability of HIV has carried important implications for the diagnosis, treatment and prevention as well as epidemiologic investigations. The present review describes important definitions and geographical distribution of subtypes, circulating recombinant forms and other genomic variations of HIV. The present study aimed at leading students of Biomedical Sciences and public health laboratory staff guidance to general and specific knowledge about the genomic variability of the HIV.

Incidence/mortality data analysis of all cases (<25 year (y)) diagnosed January 2005-February 2017 and cross-sectional data (December 2015). Over 12.2 years, 144 cases with type 1 diabetes (T1D) were diagnosed; 43.1% were male. Diagnosis age was 0.3-22.2 y; peak was 11-12 y. 11.1% were <5 y; 29.2%, 5-<10 y; 43.1%, 10-<15 y; 13.2%, 15-<20 y; and 3.5%, 20-<25 y. The youngest is being investigated for monogenic diabetes. Measured incidence in Cercado Province (Cochabamba Department) was 2.2/100,000 children < 15 y/y, with ≈80% ascertainment, giving total incidence of 2.7/100,000 children < 15 y/y. Two had died. Crude mortality rate was 2.3/1000 patient years. Clinical data on 141 cases <35 y: mean/median HbA1c was 8.5/8.2% (69/62 mmol/mol), levels higher in adolescents. Three were on renal replacement therapy; four others had substantial renal impairment. Elevated BMI, triglycerides, and cholesterol were common: 19.1%, 18.3%, and 39.1%, respectively. Bolivia has low T1D incidence. Reasonable glycemic control is being achieved despite limited resources; however, some have serious complications and adverse cardiovascular risk factor profiles. Further attention is needed for complications.

    2011-01-01

    Background Tuberculosis (TB) in migrants is an ongoing challenge in several low TB incidence countries since a large proportion of TB in these countries occurs in migrants from high incidence countries. To meet these challenges, several countries utilize TB screening programs. The programs attempt to identify and treat those with active and/or infectious stages of the disease. In addition, screening is used to identify and manage those with latent or inactive disease after arrival. Between nations, considerable variation exists in the methods used in migration-associated TB screening. The present study aimed to compare the TB immigration medical examination requirements in selected countries of high immigration and low TB incidence rates. Methods Descriptive study of immigration TB screening programs Results 16 out of 18 eligible countries responded to the written standardized survey and phone interview. Comparisons in specific areas of TB immigration screening programs included authorities responsible for TB screening, the primary objectives of the TB screening program, the yield of detection of active TB disease, screening details and aspects of follow up for inactive pulmonary TB. No two countries had the same approach to TB screening among migrants. Important differences, common practices, common problems, evidence or lack of evidence for program specifics were noted. Conclusions In spite of common goals, there is great diversity in the processes and practices designed to mitigate the impact of migration-associated TB among nations that screen migrants for the disease. The long-term goal in decreasing migration-related introduction of TB from high to low incidence countries remains diminishing the prevalence of the disease in those high incidence locations. In the meantime, existing or planned migration screening programs for TB can be made more efficient and evidenced based.

    Osteosarcoma incidence rates in the United States peak in adolescence and in the elderly. The international patterns of osteosarcoma incidence in children have been described, whereas those for young, middle age or elderly adults have not. Using the Cancer Incidence in Five Continents, International Agency for Cancer Research database we compared incidence rates for children and adolescents (age 0-24 years), the middle age group (25-59 years) and elderly (>or=60 years) persons by world regions and individual countries. Overall, worldwide osteosarcoma incidence rates were quite similar in the younger age groups. The greatest variation in incidence rates was observed in the elderly.

    Prostate cancer is the most commonly diagnosed malignancy in men in Sweden and Geneva, and the third most common in men in Singapore. This population-based study describes trends in the incidence and mortality rates of prostate cancer in Singapore, Sweden and Geneva (Switzerland) from 1973 to 2006 and explores possible explanations for these different trends. Data from patients diagnosed with prostate cancer were extracted from national cancer registries in Singapore (n = 5,172), Sweden (n = 188,783) and Geneva (n = 5,755) from 1973 to 2006. Trends of incidence and mortality were reported using the Poisson and negative binomial regression models. The age, period and birth-cohort were tested as predictors of incidence and mortality rates of prostate cancer. Incidence rates of prostate cancer increased over all time periods for all three populations. Based on the age-period-cohort analysis, older age and later period of diagnosis were associated with a higher incidence of prostate cancer, whereas older age and earlier period were associated with higher mortality rates for prostate cancer in all three countries. This study demonstrated an overall increase in incidence rates and decrease in mortality rates in Singapore, Sweden and Geneva. Both incidence and mortality rates were much lower in Singapore. The period effect is a stronger predictor of incidence and mortality of prostate cancer than the birth-cohort effect.

    The objective of this study was to measure the incidence of concussion (scaled relative to number of athlete exposures) and recurrent concussion within 2 teams of fourth-tier junior ice hockey players (16-21 years old) during 1 regular season. A prospective cohort study called the Hockey Concussion Education Project was conducted during 1 junior ice hockey regular season (2009-2010) involving 67 male fourth-tier ice hockey players (mean age 18.2 ± 1.2 years, range 16-21 years) from 2 teams. Prior to the start of the season, every player underwent baseline assessments using the Sideline Concussion Assessment Tool 2 (SCAT2) and the Immediate Post-Concussion Assessment and Cognitive Test (ImPACT). The study protocol also required players who entered the study during the season to complete baseline SCAT2 and ImPACT testing. If the protocol was not followed, the postinjury test results of a player without true baseline test results would be compared against previously established age and gender group normative levels. Each regular season game was observed by a qualified physician and at least 1 other neutral nonphysician observer. Players who suffered a suspected concussion were evaluated at the game. If a concussion diagnosis was made, the player was subsequently examined in the physician's office for a full clinical evaluation and the SCAT2 and ImPACT were repeated. Based on these evaluations, players were counseled on the decision of when to return to play. Athlete exposure was defined as 1 game played by 1 athlete. Twenty-one concussions occurred during the 52 physician-observed games (incidence 21.5 concussions per 1000 athlete exposures). Five players experienced repeat concussions. No concussions were reported during practice sessions. A concussion was diagnosed by the physician in 19 (36.5%) of the 52 observed games. One of the 5 individuals who suffered a repeat concussion sustained his initial concussion in a regular season game that was not observed by a

    Monitoring trends in lung cancer incidence and mortality is important for the evaluation of cancer control activities. We investigated recent trends in age-standardized incidence rates by histological type of lung cancer in Osaka, Japan. Cancer incidence data for 1975-2008 were obtained from the Osaka Cancer Registry. Lung cancer mortality data with population data in Osaka during 1975-2012 were obtained from vital statistics. We examined trends in age-standardized incidence and mortality rates for all histological types and age-standardized incidence rates by histological type and age group using a joinpoint regression model. The age-standardized incidence rate of lung cancer levelled off or slightly increased from 1975-2008, with an annual percentage change of 0.3% (95% confidence interval [CI], 0.1%-0.4%) for males and 1.1% (95% CI, 0.9%-1.3%) for females, and the mortality rate decreased by 0.9% (95% CI, 1.2%-0.7%) for males and 0.5% (95% CI, 0.8%-0.3%) for females. The incidence rates of squamous cell carcinoma (SQC) and small cell carcinoma (SMC) significantly decreased for both genders, whereas that of adenocarcinoma (ADC) significantly increased among almost all age groups in both genders. The incidence rates of SQC and SMC decreased with the decline in smoking prevalence, which probably explains the change in trends in the incidence rates of lung cancer from the mid-1980s. However, the reason for the increase in ADC remains unclear. Therefore, trends in incidence rates of lung cancer should be carefully monitored, especially for ADC, and the associations between ADC and its possible risk factors should be studied.

    To determine the extent of lung cancer in Alvila. Its incidence rates and significant epidemiological aspects of the year 2012 were recorded, and the results of each 5-year period (up to 20 years) were compared with those of known studies conducted using the same methodology. A prospective study was conducted on all patients diagnosed with lung cancer in the Province of Avila throughout the year 2012. A total of 81 patients were diagnosed, of whom 70 were males and 11 females, with a mean age of 72.1 years (range: 44-91), and was higher than that found in previous studies. This gave gross, and adjusted to the standard world population, incidence rates in 2012 of 80.99 and 31.23 per 100,000, respectively, in males, and 12.97 and 5.68 per 100,000, respectively in females. These rates are lower in both sexes than those found in Alvila in 2002. In 2012, 80.25% had been smokers (90% of males and 18.18% of the women), although, on diagnosis, 68.75% had quit smoking. A clinical-radiological diagnosis was made in 9 (11.1%), with a histocytological diagnosis in 72 (88.9%). The histological types were: adenocarcinomas in 37.5%; squamous in 33.3%; microcytic in 13.8%; undifferentiated non-small cell in 11.1%; large cell in 2.77%, and carcinoid in 1.38%. The most frequent treatments were chemotherapy (50.6%), symptomatic (23.4%), and surgery (12.3%). The incidence of lung cancer in Avila has decreased in both sexes in the last 10 years. In 2012, the patients have been older, the majority with adenocarcinoma histology, and receiving chemotherapy. Copyright © 2014 Sociedad Española de Médicos de Atención Primaria (SEMERGEN).

    To examine the incident rate of tuberculosis (TB) and its associates among adults with type 2 diabetes in Shanghai, China. We conducted a retrospective cohort study among 170 399 patients with type 2 diabetes aged ≥18 years who were registered in Shanghai community-based diabetes management system between 2004 and 2009. Their TB status was tracked until 31 December 2014. Cox regression was performed to identify the risk factors for TB. We documented 785 new TB cases during 654 977 person-years of follow-up. The incident rate of TB was 224.20 (206.69, 243.16) per 100 000 person-years among men and 51.34 (44.75, 58.92) per 100 000 person-years among women. A 1-unit increase of BMI was associated with a risk reduction in 16% (P < 0.01) for men and a 14% (P < 0.01) reduction for women. TB cases were more likely to be insulin-dependent [men: hazard ratio = 2.13 (1.29, 3.53); women: 3.28 (1.28, 8.39)] and had a poor glucose level initially [men: 1.21 (1.15, 1.27); women: 1.27 (1.18, 1.37)]. The risk factor for TB specific to men was a young age at diagnosis of diabetes, and the protective factor specific to women was actively engaging in physical activity. TB incident rate among patients with type 2 diabetes was substantially higher among men than among women. The risk of TB was reversely associated with initial BMI. The severity of poor glucose control among patients with diabetes was also linearly associated with the risk of TB. © 2017 John Wiley & Sons Ltd.

    Birmingham is a densely populated, industrial city with a high social deprivation index and large black (B) and Indo-Asian (I) populations. End stage renal failure is known to be more common in ethnic minorities and urban communities. Workforce planning requires accurate epidemiological data but most studies of the effect of ethnicity in the UK are from the early 1990s. RRT acceptance rates for adults (>16 years) in Birmingham were calculated for the 5-year periods 1990-5 and 1999-2004 using the 1991 and 2001 UK population census datasets and local programmes data. The adult population of Birmingham Health Authority increased slightly (961,041 in 1991 v 977,099 in 2001) but the proportion of W fell (82.7% to 74.3%) while B (5.3% to 7.0%) and I (10.4% to 17.2%) both increased.Median age was lower for I (33.5 1991, 32.9 2001) than B(33.8 1991, 37.4 2001) and W (45.1 1991, 45.9 2001).Numbers of new patients increased by 29% in W, 98% in B and 109% in I. There was also a substantial increase in acceptance rates (W 92 to 129 pmp, I 175 to 243 pmp, B 191 to 278 pmp) but the proportional increase in I (26.9%) was less than in W (41.5%) or B (48.2%). This is because almost all the increase in RRT acceptance rates for all ethnic groups was seen in the over 55 age group (256 pmp 1991, 481 pmp 2001) but 85% of the population growth for I was in the under 55 age group. In all ethnic groups there was a striking increase in acceptance rates for the over 70's (W 177 to 440 pmp, I 536 to 1711 pmp, B 301 to 1858 pmp). All acceptance rates were equivalent to the highest previously described in the UK. This may be due to local factors including social deprivation, availability of care and physicians attitudes. The increase in patient numbers was due to rising ethnic minority populations and increasing acceptance rates, especially in the elderly.The take-on rate is likely to rise disproportionately for I as the population ages over the next 10 years. This indicates that the future

    The terrorist attacks that occurred on September 11, 2001 (hereafter referred to as 9/11) in the United States had a profound impact on the physical and mental health of Americans, but the effects beyond the United States are largely unknown. To understand the wider aftermath, we examined...... the consequences of the 9/11 attacks on mental disorders in the Kingdom of Denmark. Utilizing population data from the Danish Psychiatric Central Research Register from 1995 to 2012, we used a time-series intervention approach to estimate the change in the incidence rate of mental disorders after the 9/11 attacks...

    Autonomic nervous system (ANS) dysfunction plays a role in atrial fibrillation (AF) initiation. Cardiorespiratory fitness modulates ANS function and is inversely associated with resting heart rate (RHR) and risk of AF. Thus, we sought to study the association between RHR, as a surrogate for ANS function, and incident AF independent of exercise capacity (EC). We analyzed 51,436 subjects without previous AF who underwent a clinically indicated exercise stress test. Incident AF was ascertained through claims files. RHR was measured before stress testing, and EC was estimated by peak metabolic equivalents of task. We studied the association between RHR categories (85 beats/min) and incident AF using Cox models adjusted for risk factors and for EC. We tested for interaction between RHR and age, gender, smoking, and EC. Mean (SD) age was 53 (13) years, 53% were men, and 28% were black. Participants with RHR 85 beats/min was not associated with AF risk after adjusting for EC. Results for RHR analyzed continuously and by quartile were similar. No interaction was seen. In conclusion, subjects with low RHR at all levels of EC are at increased risk of AF and may benefit from heart rhythm surveillance, particularly in the presence of other AF risk factors.

    A surveillance system for self-harm has not been established in Hong Kong. The existing data source has an unknown degree of underreporting, and therefore a capture-recapture method has been proposed to correct for the incompleteness. To assess the underestimation of the incidence of self-harm cases presenting to hospital in Hong Kong using a capture and recapture method. Two different yet overlapping hospital administrative datasets of self-harm were obtained from all public hospitals in Hong Kong. From 2002 to 2011, 59,473 distinct episodes involving 36,411 patients were identified. A capture-recapture model considering heterogeneous capture probabilities was applied to estimate the number of self-harm episodes. The estimated number of self-harm incidence was 79,923, equally shared by females and males. Cases of self-harm by females were more likely to be ascertained than those by males. The estimated annual incidence rate of self-harm in Hong Kong from 2002 to 2011 ranged from 96.4 in 2010 to 132.7 in 2002. The proposed method does not include patients who required no medical attention and those where the patient consulted private doctors. The capture-recapture model is a useful method for adjusting the underestimation of self-harm cases from existing databases when surveillance system is not available and to reveal some hidden patterns.

    To investigate the independent associations of proteinuria and the estimated glomerular filtration rate (eGFR) with incident hypertension. We investigated 29,181 Japanese males 18-59years old without hypertension in 2000 and examined whether proteinuria and the eGFR predicted incident hypertension independently over 10years. Incident hypertension was defined as a newly detected blood pressure of ≥140/90mmHg and/or the initiation of antihypertensive drugs. Proteinuria and the eGFR were categorized as dipstick negative (reference), trace or ≥1+ and ≥60 (reference), 50-59.9 or 50ml/min/1.73m(2), respectively. Cox proportional hazards models were used to estimate the hazard ratios (HRs) of incident hypertension. At baseline, 236 (0.8%) and 477 (1.6%) participants had trace and ≥1+ dipstick proteinuria, while 1416 (4.9%) and 129 (0.4%) participants had an eGFR of 50-59.9 and 50ml/min/1.73m(2), respectively. The adjusted HRs were significant for proteinuria ≥1+ (HRs 1.20, 95% CI: 1.06-1.35) and an eGFR of 50ml/min/1.73m(2) (1.29, 1.03-1.61). When two non-referent categories were combined (dipstick≥trace vs. negative and eGFR<60 vs. ≥60ml/min/1.73m(2)), the association was more significant for proteinuria (1.15, 1.04-1.27) than for eGFR (0.99, 0.92-1.07). Proteinuria and a reduced eGFR are independently associated with future hypertension in young to middle-aged Japanese males. Copyright © 2013 The Authors. Published by Elsevier Inc.

    To examine the factors associated with gynecologic cancer mortality risks, to estimate the mortality-to-incidence rate ratios (MIR) in Trinidad and Tobago (TT), and to compare the MIRs to those of select countries. Data on 3,915 incident gynecologic cancers reported to the National Cancer Registry of TT from 1 January 1995 to 31 December 2009 were analyzed using proportional hazards models to determine factors associated with mortality. MIRs for cervical, endometrial, and ovarian cancers were calculated using cancer registry data (TT), GLOBOCAN 2012 incidence data, and WHO Mortality Database 2012 data (WHO regions and select countries). Among the 3,915 incident gynecologic cancers diagnosed in TT during the study period, 1,795 (45.8%) were cervical, 1,259 (32.2%) were endometrial, and 861 (22.0%) were ovarian cancers. Older age, African ancestry, geographic residence, tumor stage, and treatment non-receipt were associated with increased gynecologic cancer mortality in TT. Compared to GLOBOCAN 2012 data, TT MIR estimates for cervical (0.49 vs. 0.53), endometrial (0.61 vs. 0.65), and ovarian cancers (0.32 vs. 0.48) were elevated. While the Caribbean region had intermediate gynecologic cancer MIRs, MIRs in TT were among the highest of the countries examined in the Caribbean region. Given its status as a high-income economy, the relatively high gynecologic cancer MIRs observed in TT are striking. These findings highlight the urgent need for improved cancer surveillance, screening, and treatment for these (and other) cancers in this Caribbean nation.

    Synthetic drugs are replacing traditional ones and becoming the main popular ones gradually, which have given rise to serious social issues in recent years. In this paper, a synthetic drugs transmission model with psychological addicts and general contact rate is proposed. The local and global stabilities are decided by the basic reproduction number R0. By analyzing the sensitivity of parameters, we obtain that controlling psychological addiction is better than drugs treatment. These results are verified by numerical simulations.

  14. Worldwide regulations for mycotoxins.

    Since the discovery of the aflatoxins in the 1960s, regulations have been established in many countries to protect the consumer from the harmful effects of mycotoxins that may contaminate foodstuffs. Various factors play a role in the decision-making process of setting limits for mycotoxins. These include scientific factors such as the availability of toxicological data, survey data, knowledge about the distribution of mycotoxins in commodities, and analytical methodology. Economical and political factors such as commercial interests and sufficiency of food supply have their impact as well. International enquiry's on existing mycotoxin legislation in foodstuffs and animal feedstuffs have been carried out several times in the 1980s and 1990s and details about tolerances, legal basis, responsible authorities, official protocols of analysis and sampling have been published. Recently a comprehensive update on worldwide regulations was published as FAO Food and Nutrition Paper 64. It appeared that at least 77 countries now have specific regulations for mycotoxins, 13 countries are known to have no specific regulations, whereas no data are available for about 50 countries, many of them in Africa. Over the years, a large diversity in tolerance levels for mycotoxins has remained. Some free trade zones (EU, MERCOSUR) are in the process of harmonizing the limits and regulations for mycotoxins in their respective member states, but it is not likely that worldwide harmonized limits for mycotoxins will soon be within reach.

    Increasing levels of resting heart rate are associated with increased risk of developing hypertension and cardiovascular disease, and seem to play a role in the progression of heart failure. The shape of the association between resting heart rate and risk of developing heart failure has not been examined in healthy individuals of the general population. Hazard ratios (HRs) of heart failure comparing categories of resting heart rate [51-60 b.p.m. (reference), 61-70 b.p.m., 71-80 b.p.m., 81-90 b.p.m., and 91-100 b.p.m.] were calculated in apparently healthy men (9805) and women (12 321) aged 39-79 participating in the 'European Prospective Investigation into Cancer and Nutrition' (EPIC) study in Norfolk. During a mean follow-up of 12.9 years, 1356 incident cases of heart failure occurred. In participants without potential heart rate-modifying medication, age- and sex-adjusted incidence rates of heart failure were 3.3, 3.7, 4.0, 5.1, and 5.5 per 1000 person-years for increasing categories of resting heart rate; compared with the reference category, HRs and 95% confidence intervals (CI) for increasing categories of resting heart rate were 1.08 (0.88-1.34), 1.17 (0.94-1.46), 1.39 (1.08-1.79), and 1.42 (1.00-2.03), respectively, in multivariable analysis adjusting for age, sex, body mass index, systolic blood pressure, prevalent diabetes, cholesterol concentration, social class, educational level, smoking, and physical activity. Within the reference range of resting heart rate (50-100 b.p.m.) each 10 b.p.m. increase was associated with an 11% increase in hazard of heart failure in multivariable analysis. The results did not change materially after adjusting for myocardial infarction and coronary heart disease events during follow up (1.12, 1.06-1.18). Resting heart rate shows a graded association with hazard of heart failure in apparently healthy men and women which is not mediated by coronary heart disease. Further study is needed to examine the underlying mechanisms.

    Full Text Available Observational and ecological studies are generally used to determine the presence of effect of cancer risk-modifying factors. Researchers generally agree that environmental factors such as smoking, alcohol consumption, poor diet, lack of physical activity, and low serum 25-hdyroxyvitamin D levels are important cancer risk factors. This ecological study used age-adjusted incidence rates for 21 cancers for 157 countries (87 with high-quality data in 2008 with respect to dietary supply and other factors, including per capita gross domestic product, life expectancy, lung cancer incidence rate (an index for smoking, and latitude (an index for solar ultraviolet-B doses. The factors found to correlate strongly with multiple types of cancer were lung cancer (direct correlation with 12 types of cancer, energy derived from animal products (direct correlation with 12 types of cancer, inverse with two, latitude (direct correlation with six types, inverse correlation with three, and per capita gross national product (five types. Life expectancy and sweeteners directly correlated with three cancers, animal fat with two, and alcohol with one. Consumption of animal products correlated with cancer incidence with a lag time of 15–25 years. Types of cancer which correlated strongly with animal product consumption, tended to correlate weakly with latitude; this occurred for 11 cancers for the entire set of countries. Regression results were somewhat different for the 87 high-quality country data set and the 157-country set. Single-country ecological studies have inversely correlated nearly all of these cancers with solar ultraviolet-B doses. These results can provide guidance for prevention of cancer.

    Background Tracheal stenosis is one of the worst complications associated with endotracheal intubation and it is the most common reason for reconstructive airway surgeries. Due to various local risk factors, the incidence rate of tracheal stenosis may vary in different countries. In order to estimate the incidence rate of post-intubation tracheal stenosis (PITS) in patients admitted to an intensive care unit (ICU), a follow-up study was planned. As there was no similar methodological model in the literature, a feasibility step was also designed to examine the whole project and to enhance the follow-up rate. Objectives To estimate the PITS incidence rate in patients admitted to ICUs, as well as to evaluate the feasibility of the study. Methods This prospective cohort study was conducted in five hospitals in two provinces (Tehran and Arak) of Iran from November 2011 to March 2013. All patients admitted to ICUs who underwent more than 24 hours of endotracheal intubation were included. Upon their discharge from the ICUs, the patients received oral and written educational materials intended to ensure a more successful follow-up. The patients were asked to come back for follow-up three months after their extubation, or sooner in case of any symptoms developing. Those with dyspnea or stridor underwent a bronchoscopy. The asymptomatic patients were given a spirometry and then they underwent a bronchoscopy if the flow-volume loop suggested airway stenosis. Results Some seventy-three patients (70% men) were included in the study. Multiple trauma secondary to motor vehicle accidents (52%) was the most common cause of intubation. Follow-ups were completed in only 14 (19.2%, CI = 0.109 - 0.300) patients. One patient (7%, CI = 0.007 - 0.288) developed symptomatic tracheal stenosis that was confirmed by bronchoscopy. The barriers to a successful follow-up were assessed on three levels: ineffective oral education upon discharge, improper usage of educational materials, and

    The objective of cervical cancer screening is to lower the incidence and mortality rates of the disease. The Nordic countries have a long experience in cervical cancer screening. Based on this experience this study evaluates the UICC and EC guidelines regarding the effectiveness of organized vs. spontaneous screening, targeted age groups and screening intervals. The study analyses the features of the Icelandic and the Nordic screening programmes and the observed trends in the incidence and mortality rates in these countries through 1995. It also analyses the trends for cytologic preinvasive lesions at first visit and at second and later visits after a normal test(s). The frequency of histologic lesions was calculated for the birth cohort 1920-1926 from the age of 60 and among women referred for colposcopic examination in 1994. Organized screening started in all the Nordic countries except Norway soon after 1960. Up to 1985 the target age group and screening interval were most intensive in Iceland. All countries intensified the screening intervals after 1985. The reduction in both the mortality and the incidence rates was greatest in Iceland and Finland, intermediate in Sweden and Denmark, and lowest in Norway but in that country organized screening started in 1994. The age-specific incidence in the 20-29 age group has been increasing since 1971 in all the Nordic countries, except in Finland. In Iceland screening has greatly affected the rate of all stages of squamous cell carcinoma, but not the rate of adeno-and adenosquamous carcinomas. The prevalence of preinvasive disease has increased significantly since 1980. The rate of moderate to high-grade cytologic changes begins increasing as early as at 20 years of age and moderate to high-grade histologic lesions start to accumulate at 24 to 36 months after a normal smear. The rate of these lesions decreases with the number of negative smears taken. Moderate to high-grade histologic lesions and invasive cancer are

    Full Text Available Abstract Background Poor data exist on the influence of psychosocial variables on the female/male ratio of depression because of the small number of cases and the resulting limited numbers of variables available for investigation. For this investigation a large number of first admitted depressed patients (N = 2599 was available which offered the unique opportunity to calculate age specific sex ratios for different marital and employment status categories. Methods Age and sex specific population based depression rates were calculated for first ever admissions for single year intervals. Moving averages with interpolated corrections for marginal values in the age distribution were employed. Results For the total group the female/male ratio of depression showed an inverted U-shape over the life-cycle. This pattern was influenced by the group of married persons, which showed a sex-ratio of 3:1 between the age of 30–50, but ratios of around 1:1 at younger and older ages. For not married persons the female/male ratio was already around 2:1 at the age of 18 and rose to 2.5:1 in mid-life and declined to 1 at around 55. The almost parallel decline of depression rates in employed men and women resulted in a female/male ratio of about 2:1 from age 18 to age 50 and became 1 after the age of 60. The female/male ratio among the not employed was about 1, in mid-life it became negative. Conclusions Our analyses show that the gender-gap in first admitted depressed patients is age dependent and that psychosocial factors modify the sex ratio.

    A silicon micro-strip detector module from the LHCb/Velo detector was exposed to proton rates in the range of $2\\times 10^9$ to $9\\times 10^{12}$ protons per pulse. The beam energy was $1.4~\\rm{GeV}$ and the pulse length was 200 ns, concentrated on a surface area of approximately $0.5~{\\rm cm^2}$. The sensor is of $n$-in-$n$ type and AC-coupled to a front-end chip in $0.25~\\rm{\\mu m}$ CMOS technology. Both the active sensor area and the readout chips were exposed to successive beam pulses, at perpendicular impact. The module was powered with both low and high voltage, and read out during and between beam exposures. We report on the measurements of the backplane bias voltage collapse, of the leakage current, as well as noise and pedestal variations of the front-end readout. No degradation or damage was observed beyond those normally expected from the accumulated radiation dose.

    Falls of individuals with dementia are frequent, dangerous, and costly. Early detection and access to the history of a fall is crucial for efficient care and secondary prevention in cognitively impaired individuals. However, most falls remain unwitnessed events. Furthermore, understanding why and how a fall occurred is a challenge. Video capture and secure transmission of real-world falls thus stands as a promising assistive tool. The objective of this study was to analyze how continuous video monitoring and review of falls of individuals with dementia can support better quality of care. A pilot observational study (July-September 2016) was carried out in a Californian memory care facility. Falls were video-captured (24×7), thanks to 43 wall-mounted cameras (deployed in all common areas and in 10 out of 40 private bedrooms of consenting residents and families). Video review was provided to facility staff, thanks to a customized mobile device app. The outcome measures were the count of residents' falls happening in the video-covered areas, the acceptability of video recording, the analysis of video review, and video replay possibilities for care practice. Over 3 months, 16 falls were video-captured. A drop in fall rate was observed in the last month of the study. Acceptability was good. Video review enabled screening for the severity of falls and fall-related injuries. Video replay enabled identifying cognitive-behavioral deficiencies and environmental circumstances contributing to the fall. This allowed for secondary prevention in high-risk multi-faller individuals and for updated facility care policies regarding a safer living environment for all residents. Video monitoring offers high potential to support conventional care in memory care facilities.

    The purpose of this study was to investigate the chronological changes in the age-adjusted incidence rates (AAIRs) of cancers of all sites as well as of 20 major cancers worldwide, which were tested using 5 consecutive IARC Data books from the early 1960s to mid-1980s. We used log-transformed AAIR data (log AAIR) for the statistical analysis of group data. For the follow-up study of a given neoplasia, we prepared 5 world populations using 5 international Data books, and calculated the mean and standard deviation of log AAIR for each tumor, for each sex and for each of 5 world populations for the follow-up study of cancer risks of 20 major cancers as well as cancers of all sites. The results obtained are as follows: a) the log AAIR of cancers of all sites, as compared between the early 1960s group and the mid-1980s group, significantly increased in both the male population (+32.1%) and the female population (+18.0%). b) The remarkable decrease of risks (log AAIRs) for cancers of the stomach and the uterine cervix (non-Western type cancers) and a remarkable increase of risks for cancers of the lung of both sexes, and of the female breast (Western type cancers), were observed from the early 1960s to the mid-1980s--a finding to indicate that the Westernization influences the cancer risk world-wide. c) The follow-up study of cancer risks of individual tumors in both individual population units and the world populations revealed the presence of a number of cancer risk changes that do not fit the definition of "Westernization of cancer risk pattern": i) an abrupt and remarkable increase of skin cancer risk that took place in both the East and the West in the time range of early 1960s to early 1970s; ii) a remarkable increase of liver cancer risk in both the East and the West in the early 1960s to mid-1980s; iii) sex-discriminative cancer risk increase, as exemplified by the contrast between significant risk increase of male sex organs (the prostate and the testis) and

    Full Text Available BACKGROUND: Chronic kidney disease (CKD independently increases the risk of death and cardiovascular disease (CVD in the general population. However, the relationship between estimated glomerular filtration rate (eGFR and CVD/death risk in a general population at low risk of CVD has not been explored so far. DESIGN: Baseline and longitudinal data of 1465 men and 1459 women aged 35-74 years participating to the MATISS study, an Italian general population cohort, were used to evaluate the role of eGFR in the prediction of all-cause mortality and incident CVD. METHODS: Bio-bank stored sera were used to evaluate eGFR at baseline. Serum creatinine was measured on thawed samples by means of an IDMS-calibrated enzymatic method. eGFR was calculated by the CKD-EPI formula. RESULTS: At baseline, less than 2% of enrolled persons had eGFR < 60 mL/min/1.73 m(2 and more than 70% had a 10-year cardiovascular risk score < 10%. In people 60 or more years old, the first and the last eGFR quintiles (<90 and ≥109 mL/min/1.73 m(2, respectively were associated to an increased risk for both all-cause mortality (hazard ratio 1.6, 95% confidence interval 1.2-2.1 and 4.3, 1.6-11.7, respectively and incident CVD (1.6, 1.0-2.4 and 7.0, 2.2-22.9, respectively, even if adjusted for classical risk factors. CONCLUSIONS: These findings strongly suggest that in an elderly, general population at low risk of CVD and low prevalence of reduced renal filtration, even a modest eGFR reduction is related to all-cause mortality and CVD incidence, underlying the potential benefit to this population of considering eGFR for their risk prediction.

    Abstract Background Female cancer, especially breast and gynecologic cancers are considered multistage disease, highly influenced by risk and protective factors and/or screening preventive modalities. Consequences of all these factors result in the trend of change over time. Methods In this comparative study, based on data of national cancer registry of Iran 2004 published by Iranian Ministry of Health, age — standard incidence rate (ASR) according to the world population was calculated in all reported gynecologic and breast cancers. Source of all subjects are pathologic based. In the next step, the calculated ASR of Iran and those of the other countries in 2004 were compared to GLOBOCAN ASR reports of 2008. Results In Iran ASR of breast cancer 2004 (24.93) changed to 18.4 in 2008. Ovarian cancer ASR of 2004, 3.07 was 3.1 in 2008. Endometrial cancer ASR in 2004 (2.29) was 1.7 in 2008. Cervical cancer ASR of 1.71 in 2004 was 2.2 in 2008. Conclusions In Iran incidence trend of breast and endometrium are decreasing in the same direction of USA and Australia. Increasing trend of ovary and cervix ASR in Iran is in the inverse direction of USA and Australia which are decreasing. Future studies to find out the same trend or any changes, might develop these findings and improve consequent practical decisions based on results of this study and complementary future studies.

    Full Text Available Fishing is one of the oldest occupations, which over the years has gone through several stages. In the economic terms the increase in intensive industrial system of the fish is advantageous because the specific energy consumption is low, given that they not need to maintain body temperature at high temperatures. Having regard to demographic trends in continue increasing, and the tendency of decrease fisheries leads to increased the production of aquaculture fish by order to ensure enough quantity and quality. The purpose of this paper is to highlight the evolution of fish production worldwide and in particular to show the evolution of production of fish from fisheries and aquaculture. To highlight the evolution global fish production given two ways to get fish respectively from aquaculture and fisheries, that have used data from FAOSTAT for 2007-2012. Also we can see that approximately 90% of the fish production is fished in the sea and only 10% in the territorial waters. The fish production in Africa had an ascending trend in the period under review. Analyzing fish production the share of total world continents is noted that Asia has a share of 68% in 2007 and increase to 73% in 2012.

    Full Text Available Abstract Background We aimed to investigate incidence rates of urinary tract infections in Dutch general practice and their association with gender, season and urbanisation level, and to analyse prescription and referral in case of urinary tract infections. Method During one calendar year, 195 general practitioners in 104 practices in the Netherlands registered all their patient contacts. This study was performed by the Netherlands Institute for Health Services Research (NIVEL in 2001. Of 82,053 children aged 0 to 18 years, the following variables were collected: number of episodes per patient, number of contacts per episode, month of the year in which the diagnosis of urinary tract infection was made, age, gender, urbanisation level, drug prescription and referral. Results The overall incidence rate was 19 episodes per 1000 person years. The incidence rate in girls was 8 times as high as in boys. The incidence rate in smaller cities and rural areas was 2 times as high as in the three largest cities. Throughout the year, incidence rates varied with a decrease in summertime for children at the age of 0 to 12 years. Of the prescriptions, 66% were in accordance with current guidelines, but only 18% of the children who had an indication were actually referred. Conclusion This study shows that incidence rates of urinary tract infections are not only related to gender and season, but also to urbanisation. General practitioners in the Netherlands frequently do not follow the clinical guidelines for urinary tract infections, especially with respect to referral.

    In this paper, a delayed computer virus propagation model with a saturation incidence rate and a time delay describing temporary immune period is proposed and its dynamical behaviors are studied. The threshold value ℜ0 is given to determine whether the virus dies out completely. By comparison arguments and iteration technique, sufficient conditions are obtained for the global asymptotic stabilities of the virus-free equilibrium and the virus equilibrium. Taking the delay as a parameter, local Hopf bifurcations are demonstrated. Furthermore, the direction of Hopf bifurcation and the stabilities of the bifurcating periodic solutions are determined by the normal form theory and the center manifold theorem for functional differential equations (FDEs). Finally, numerical simulations are carried out to illustrate the main theoretical results.

    Chilean red chili peppers contaminated with aflatoxins were reported in a previous study. If the development of gallbladder cancer (GBC) in Chile is associated with a high level of consumption of aflatoxin-contaminated red chili peppers, such peppers from other countries having a high GBC incidence rate may also be contaminated with aflatoxins. We aimed to determine whether this might be the case for red chili peppers from Bolivia and Peru. A total of 7 samples (3 from Bolivia, 4 from Peru) and 3 controls (2 from China, 1 from Japan) were evaluated. Aflatoxins were extracted with acetonitrile:water (9:1, v/v) and eluted through an immuno-affinity column. The concentrations of aflatoxins B1, B2, G1, and G2 were measured using high-performance liquid chromatography (HPLC), and then the detected aflatoxins were identified using HPLC-mass spectrometry. In some but not all of the samples from Bolivia and Peru, aflatoxin B1 or aflatoxins B1 and B2 were detected. In particular, aflatoxin B1 or total aflatoxin concentrations in a Bolivian samples were above the maximum levels for aflatoxins in spices proposed by the European Commission. Red chili peppers from Bolivia and Peru consumed by populations having high GBC incidence rates would appear to be contaminated with aflatoxins. These data suggest the possibility that a high level of consumption of aflatoxin-contaminated red chili peppers is related to the development of GBC, and the association between the two should be confirmed by a case-control study.

    Breast and prostate cancer share similarities and likely represent homologous cancers in females and males, respectively. The role of hormones such as testosterone and estrogen in carcinogenesis is well established. Despite worldwide research efforts, the pathogenesis of these diseases is largely not well understood. Personal care products containing estrogens or xenoestrogens have raised concern as a breast cancer risk, especially in young African-American women. In the United States (US) there is a parallel rise in the incidence in breast and prostate cancer compared to selected non-hormone dependent tumors. Observed US and global breast and prostate cancer incidence increases were occurring before exogenous hormone replacement and xenoestrogen exposure were commonplace. An unintentional, inadvertent, and long term hormone exposure may occur from transdermal absorption of sex hormones and pheromones (androgens) from axillary apocrine sweat gland obstruction by aluminum-based antiperspirants. The global rise in antiperspirant use parallels rises in breast and prostate cancer incidence and mortality rates. A multi-disciplinary literature based set of evidence is presented on how such a link is possible, to prompt confirmatory investigations in the pursuit of unmet needs in breast and prostate cancer etiology and prevention.

    To study recent time trends in the incidence of diagnosed anorexia nervosa (AN) and bulimia nervosa (BN) based on nationwide psychiatric register data. The Danish Psychiatric Central Research Registry was used to identify the incidence of diagnosed cases with AN and BN at the ages of 4-65 years from 1995 to 2010. Age- and sex-adjusted incidence rates per 100,000 person-years were calculated and were adjusted for time trends in the total number of people diagnosed in psychiatry. Time trends were analyzed using JoinPoint regression analysis. A total of N = 5,902 persons had a first-time incidence of AN, and a total of N = 5,113 had first-time incidence of BN. Incidence rates increased for AN from 6.4 to 12.6 per 100,000 person-years, and for BN from 6.3 to 7.2 per 100,000 person-years. In 2010, the male-to-female ratio was 1:8 for AN, and 1:20 for BN. There was an earlier onset for AN than for BN, and age at incidence decreased during the observation period for AN but not for BN. A sizeable part of the increasing incidence rates for AN and in particular, the younger AN age groups, could be attributed to an increase in the total number of N = 249,607 persons with first-time diagnoses in psychiatry. Incidence rates had increased slightly for AN, but were stable for BN across 16 years in this nationwide study and to a large extent were reflective of a general increase in diagnosed mental disorders. © 2015 Wiley Periodicals, Inc.

    Dogslife collects data directly from owners of Labrador Retrievers across the UK including information regarding signs of illness irrespective of whether the signs precipitated a veterinary visit. In December 2015, the cohort comprised 6084 dogs aged up to six years and their owners had made 2687 and 2601 reports of diarrhoea and vomiting respectively. The co-occurrence of vomiting and diarrhoea with other signs was described and the frequencies and durations of the two signs were examined with reference to veterinary visitation. Age-specific illness rates were described and Cox Proportional Hazards models were used to estimate risk factors. Just 37% of diarrhoea reports were associated with a veterinary visit and the proportion was even lower for vomiting at 28%; indicating that studies of veterinary practice data miss the majority of signs of gastrointestinal upset. In terms of frequency and duration, diarrhoea typically needed to last two days before the dog would be taken to the vet but if the dog vomited at least every six hours, the owner would be more likely to take the dog to the vet after one day. The illness rates of both signs peaked when the dogs were aged between three and six months. There was also a seasonal pattern to the incidents with the lowest hazards for both in May. Diarrhoea incidents peaked in August-September each year but, while vomiting appeared to be higher in September, it peaked in February. Having another dog in the household was associated with a lower hazard for both vomiting and diarrhoea but having a cat was only associated with a reduced hazard of vomiting. In addition to the distinct seasonal patterns of reporting, there were clear differences in the geographic risks for the two signs. The hazard of diarrhoea was positively associated with human population density within Great Britain (according to home post code) whereas no significant geographical association was found with vomiting. This study is particularly relevant for dog

    Very little data exist on the incidence and burden of cancer in the individual Caribbean countries. Some data are available for larger areas, reported under a bigger geographical region; Latin America and the Caribbean, but many of the individual countries are not included. One of the main reasons is a lack of official cancer registries. Data are usually collected from hospital records or private physician records, and since it is not in an official registry, these data are not always accessible for inclusion in databases such as SEER and GLOBOCAN. Grenada is one of the countries that currently does not have a registry. Our aim is to report on the incidence for head and neck cancer with subcategories; hypopharynx, oropharynx, oral cavity, salivary glands, and larynx from data collected by the sole ear nose and throat specialist over a 20-year period. The age adjusted incidence per 100,000 for these cancers, whether combined or individually, is lower than that of similar populations. The incidence in males is only slightly higher than those reported in some parts of Africa. In females, only Eastern Africa is reported to have a lower incidence than that found in our study. While the incidence of oral cancers is lower than that of African Americans, the survival rate is comparable. Socioeconomic status, lack of infrastructure, and advanced stage at diagnosis appear to be closely related to the survival rate. Incidence reports suggest that incidence of head and neck cancers in individuals of African descent is lower than other populations. It is therefore not surprising that the incidence in Grenada is relatively low, although the incidence may be underestimated.

    Community-acquired pneumonia (CAP) is frequently associated with the very young and the elderly but is a largely underrecognized burden among working-age adults. Although the burden of CAP among the elderly has been established, there are limited data on the economic burden of CAP in the employed population. To assess the economic impact of CAP in US working-age adults from an employer perspective by estimating the incidence rate and costs of healthcare, sick time, and short-term disability for this patient population. This retrospective cohort study is based on data from 2 Truven Health Analytics databases. The study population consisted of commercially insured active employees aged 18 to 64 years, early retirees aged Descriptive statistics were used to compare healthcare (ie, medical and pharmacy) costs, sick time, and short-term disability costs between the cohorts with and without CAP. Linear regression was used to estimate the average annual incremental healthcare cost in employed patients with inpatient or outpatient CAP versus individuals without CAP. Study eligibility was met by 12,502,017 employed individuals, including 123,920 with CAP and 12,378,097 without CAP; the overall incidence rate of CAP was 10.6 per 1000 person-years. Among individuals with and without CAP, the costs of healthcare, sick time, and short-term disability increased with advancing age and with higher risk status. The mean annual healthcare costs were $20,961 for patients with CAP and $3783 for individuals without CAP. Overall, the mean costs of sick time and short-term disability were $1129 and $1016, respectively, in active employees with CAP, and $853 and $322, respectively, in their counterparts without CAP. Compared with individuals without CAP, the average annual incremental healthcare cost ranged from $39,889 to $113,837 for inpatient management of patients with CAP and from $4170 to $31,524 for outpatient management of patients with CAP, depending on the risk level.

    Population-based studies of the incidence of tuberculosis in cancer patients according to the type of cancer are limited. We investigated the cancer-specific incidence of tuberculosis in a nationwide population-based cohort in a country with an intermediate burden of tuberculosis.We used mandatory National Health Insurance claims data to construct a cancer cohort of adults (aged 20-99 years) with newly diagnosed malignancies other than lung cancer, from January 2008 to December 2012. Patients who developed tuberculosis in this period were identified in the cancer cohort and the general population. Standardized incidence ratios (SIRs) of tuberculosis in the cancer cohort according to type of cancer and time after cancer diagnosis were calculated by comparing the observed incidence rates with those inferred from the age- and gender-specific incidence rates in the general population.A total of 855,382 cancer patients and 1589,876 person-years (py) were observed. A total of 5745 patients developed tuberculosis; the mean incidence rate was 361.3 per 100,000 py, and the SIR was 2.22 (95% confidence interval [CI], 2.17-2.27). The incidence rate was highest for hematologic malignancy and lowest for thyroid cancer. It was also highest as 650.1 per 100,000 py, with SIR of 3.70 (CI, 3.57-3.83) for the first 6 months after diagnosis of malignancy and then declined. However, it still remained higher than that of the general population after 24 months (SIR = 1.43, CI, 1.36-1.51).The incidence of tuberculosis increases after diagnosis in patients with malignancies. The risk of tuberculosis differs according to the type of cancer and remains elevated even 24 months after cancer diagnosis. Tuberculosis should be considered an important comorbidity in patients with malignancies.

    To calculate the incidence rates of ocular complications and vision loss in HLA-B27-associated uveitis and to explore the effect of chronic inflammation on clinical outcomes. Retrospective longitudinal cohort study. The clinical records of 99 patients (148 uveitis-affected eyes) with HLA-B27-associated uveitis seen at a tertiary care center were included. The main outcome measures were ocular complications (posterior iris synechiae, band keratopathy, posterior subcapsular [PSC] cataracts, ocular hypertension, hypotony, cystoid macular edema, and epiretinal membrane) and vision loss. Anterior chamber inflammation was defined as ≥1+ grade inflammation. Chronic uveitis was defined as persistent inflammation with relapse in 3 months after reviewing the patient's entire clinical course. The clinical course was most commonly acute/recurrent (75%) or chronic (20%). The most common complications to develop during follow-up were ocular hypertension (0.10/eye-year) and PSC cataracts (0.09/eye-year). In multivariate analysis, the presence of posterior synechiae at presentation, inflammation, corticosteroid-sparing therapy, corticosteroid injections, chronic disease, and male gender were associated with a statistically significant increased risk of developing vision loss (20/50 or worse). Chronic disease course was associated with a 7-fold increased risk of visual impairment (hazard ratio [HR] = 6.8, P vision loss. Patients with chronic inflammation were also at greater risk of complications. Copyright © 2010 Elsevier Inc. All rights reserved.

    Existing methods are inadequate for developing aggregate (regional and global) and long-term (several decades) passenger transport demand scenarios, since they are mainly based on simple extensions of current patterns rather than causal relationships that account for the competition among transport modes (aircraft, automobiles, buses and trains) to provide transport services. The demand scenario presented in this paper is based on two empirically proven invariances of human behavior. First, transport accounts for 10 to 15 percent of household total expenditures for those owning an automobile, and around 5 percent for non-motorized households on average (travel money budget). Second, the mean time spent traveling is approximately one hour per capita per day (travel time budget). These two budgets constraints determine the dynamics of the scenario: rising income increases per capita expenditure on travel which, in turn, increase demand for mobility. Limited travel time constraints travelers to shift to faster transport systems. The scenario is initiated with the first integrated historical data set on traffic volume in 11 world regions and the globe from 1960 to 1990 for all major modes of motorized transport. World average per capita traffic volume, which was 1,800 kilometers in 1960 and 4,2090 in 1990, is estimated to rise to 7,900 kilometers in 2020 - given a modest average increase in Gross World Product of 1.9% per year. Higher economic growth rates in Asian regions result in an increase in regional per capita traffic volume up to a factor of 5.3 from 1990 levels. Modal splits continue shifting to more flexible and faster modes of transport. At one point, passenger cars can no longer satisfy the increasing demand for speed (i.e. rising mobility within a fixed time budget). In North America it is estimated that the absolute traffic volume of automobiles will gradually decline starting in the 2010s. (author) 13 figs., 6 tabs., 35 refs.

    This study aimed to analyze incidence and mortality trends in breast cancer (BC), corpus uteri cancer (CUC), and ovarian cancer (OC) in Poland in the context of sociodemographic changes. Incidence and mortality data (1980-2013) were retrieved from the Polish National Cancer Registry, while socioeconomic data (1960-2013) were obtained from the World Bank. Age-standardized incidence and mortality rates were calculated by direct standardization, and join-point regression was performed to describe trends using the average annual percentage change (AAPC). A significant decrease in birth and fertility rates and a large increase in gross domestic product were observed together with a decrease in the total mortality rate among women, as well as an increase in life expectancy for women. A large, significant increase in BC incidence was observed (AAPC1980-1990 2.14, AAPC1990-1996 4.71, AAPC1996-2013 2.21), with a small but significant decrease in mortality after a slight increase (AAPC1980-1994 0.52, AAPC1994-2013 -0.66). During the period 1980-2013, a significant increase in CUC incidence (AAPC1980-1994 3.7, AAPC1994-2013 1.93) was observed, with an initial mortality-rate reduction followed by a significant increase (AAPC1980-2006 -1.12, AAPC2006-2013 3.74). After the initial increase of both OC incidence and mortality from 1994, the incidence rate decreased significantly (AAPC1980-1994 2.98, AAPC1994-2013 -0.49), as did the mortality rate (AAPC1980-1994 0.52, AAPC1994-2013 -0.66). After 1994, a decrease in OC incidence was found, while the incidence of BC and CUC continued to increase. A reduction in mortality rate was observed for BC and OC predominantly at the end of the study period, while for CUC, after a long decreasing mortality trend, a significant increase was observed.

    Overdiagnosis in breast cancer screening is a topic of debate. Researchers often estimate trends in incidence prior to screening and project these to predict incidence during the screening epoch. Data was obtained from the Cancer Registry of Norway and the Norwegian Breast Cancer Screening Programme. Using breast cancer incidence prior to screening in Norway (1976-1995), incidence trends were estimated from age-period and age-cohort models. These estimates were used to predict the incidence of breast cancer in five-year age and period groups in the screening epoch (1996-2009). Excess numbers of cancers in the screening age range (6,876 cancers), and deficits in women above and below the screening age range (1,947 cancers) were observed. However, only part of the observed differences between the observed and the expected incidence can be explained by screening, as evidenced by numbers of excess cancers greater than the numbers of screen-detected cancers in some age groups and time periods. There are potential errors in estimation of overdiagnosis from screening if individual data on screening exposure and detection mode are not taken into account. For reliable estimates of overdiagnosis, it is necessary to compare excess incidence in the screening period in those actually screened with the corresponding excess in those not screened. This is the subject of ongoing research.

    This study was conducted to investigate whether incidence rates of malignant cutaneous melanoma in U.S. Department of Defense active duty military personnel differed from rates in the U.S. general population between 2000 and 2007. The study population included active duty military personnel and the general population aged 18 to 56 years. Data were obtained from the U.S. Department of Defense medical data systems and from the Surveillance Epidemiology and End Results program. Melanoma risk was estimated by incidence rate ratios (IRRs). Melanoma risk was higher among active duty personnel than the general population (IRR = 1.62, 95% confidence interval = 1.40-1.86). Incidence rates were higher for white military personnel than for white rates in general population (36.89 and 23.05 per 100,000 person-years, respectively). Rates were also increased for military men and women compared with SEER (men, 25.32 and 16.53 per 100,000; women, 30.00 and 17.55 per 100,000). Air Force service personnel had the highest rates and Army had the lowest. Melanoma rates were marginally higher among active duty military personnel than the general population between 2000 and 2007. Reprint & Copyright © 2014 Association of Military Surgeons of the U.S.

Methods Using the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) estimated glomerular filtration rate formula, we identified ambulatory adults (>22 years old) without rheumatic heart disease or prosthetic valves and with 60 ml/min/1.73 m2filtration rate10 m patient-years of follow-up (∼75% 65,000 individuals had ≥1 atrial fibrillation event (incident atrial fibrillation rate 5.1% and 5.8% excluding or including prior cardiovascular disease, or 49 and 55 per 10,000 patient-years, respectively). In both cohorts, individuals with versus without incident atrial fibrillation had lower mean estimated glomerular filtration rate (∼83 versus 95 ml/min/1.73 m2). Adjusting for age, gender, hypertension, and diabetes mellitus, overall a 10 ml/min/1.73 m2 decrease in estimated glomerular filtration rate was independently associated with a mean increase in incident atrial fibrillation of 1.5% and 2.4% in the cohorts excluding or including prior cardiovascular disease, respectively ( p filtration rate and atrial fibrillation was observed in the 90-130 ml/min/1.73 m2 range, whereas a blunted association was observed in the 60-90 ml/min/1.73 m2 range.

    Electron accelerator is an important radiation source for radiation technology, which covers broad fields such as industry, health care, food and environmental protection. There are about 1,000 electron accelerators for radiation processing worldwide. Electron accelerator has advantage over Co-60 irradiator in term of high dose rate and power, assurance of safety, and higher economic performance at larger volume of irradiation. Accelerator generating higher energy in the range of 10 MeV and high power electron beam is now commercially available. There is a trend to use high-energy electron accelerator replacing Co-60 in case of large through-put of medical products. Irradiated foods, in particular species, are on the commercial market in 35 countries. Electron accelerator is used efficiently and economically for production of new or modified polymeric materials through radiation-induced cross-linking, grafting and polymerization reaction. Another important application of electron beam is the curing of surface coatings in the manufacture of products. Electron accelerators of large capacity are used for cleaning exhaust gases in industrial scale. Economic feasibility studies of this electron beam process have shown that this technology is more cost effective than the conventional process. It should be noted that the conventional limestone process produce gypsum as a by-product, which cannot be used in some countries. By contrast, the by-product of the electron beam process is a valuable fertilizer. (Y. Tanaka)

    The objectives of this study were to determine the rate of animal bite incidents occurring in the human population of a local health department, and to determine the proportion of these canines and felines that were not up to date on their rabies vaccination at the time the incident occurred. Data were obtained from animal bite incidents reported to Wellington-Dufferin-Guelph Public Health during 2010 and 2011. Descriptive statistics of 718 eligible reports revealed the average rate of animal biting was 1.55 bites per 1000 residents per year. Approximately 54% of these animals were vaccinated against rabies, 32% were not up to date with their rabies vaccination, and the remaining 14.5% were of unknown status. The unit of analysis was the municipality, and the four outcomes of interest were: (i) number of animal bite incidents per 1000 residents, (ii) number of dog bite incidents per 1000 residents, (iii) proportion of animals involved in bite incidents that were not up to date with their rabies vaccination, and (iv) proportion of dogs that were not up to date. Associations between the outcomes and selected demographic variables were investigated using regression analysis. The number of veterinary clinics per 10,000 residents, and whether the municipality was urban or rural were identified as significant predictors for the number of animal bites per 1000 residents, and the number of dog bites. There were no significant predictors for the proportion of unvaccinated animals or dogs. Spatial clustering and the location of spatial clusters were assessed using the empirical Bayes index and spatial scan test. This analysis identified five municipalities within the health department that have a high rate of biting incidents and a high proportion of animals that were not up to date on their rabies vaccination. Such municipalities are ideal for targeted educational campaigns regarding the importance of vaccination in pets. © 2014 Blackwell Verlag GmbH.

    We determined whether decreased peak urine flow is associated with future incident lower urinary tract symptoms in men with mild to no lower urinary tract symptoms. Our population consisted of 3,140 men from the REDUCE (Reduction by Dutasteride of Prostate Cancer Events) trial with mild to no lower urinary tract symptoms, defined as I-PSS (International Prostate Symptom Score) less than 8. REDUCE was a randomized trial of dutasteride vs placebo for prostate cancer prevention in men with elevated prostate specific antigen and negative biopsy. I-PSS measures were obtained every 6 months throughout the 4-year study. The association between peak urine flow rate and progression to incident lower urinary tract symptoms, defined as the first of medical treatment, surgery or sustained and clinically significant lower urinary tract symptoms, was tested by multivariable Cox models, adjusting for various baseline characteristics and treatment arm. On multivariable analysis as a continuous variable, decreased peak urine flow rate was significantly associated with an increased risk of incident lower urinary tract symptoms (p = 0.002). Results were similar in the dutasteride and placebo arms. On univariable analysis when peak flow was categorized as 15 or greater, 10 to 14.9 and less than 10 ml per second, flow rates of 10 to 14.9 and less than 10 ml per second were associated with a significantly increased risk of incident lower urinary tract symptoms (HR 1.39, p = 0.011 and 1.67, p urinary tract symptoms a decreased peak urine flow rate is independently associated with incident lower urinary tract symptoms. If confirmed, these men should be followed closer for incident lower urinary tract symptoms. Copyright © 2017 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

  9. Increase of Prostate Cancer Incidence in Martinique

    Full Text Available Prostate cancer incidence is steadily increasing in many developed countries. Because insular populations present unique ethnic, geographical, and environmental characteristics, we analyzed the evolution of prostate cancer age-adjusted world standardized incidence rates in Martinique in comparison with that of metropolitan France. We also compared prostate cancer incidence rates, and lifestyle-related and socioeconomic markers such as life expectancy, dietary energy, and fat supply and consumption, with those in other Caribbean islands, France, UK, Sweden, and USA. The incidence rate of prostate cancer in Martinique is one of the highest reported worldwide; it is continuously growing since 1985 in an exponential mode, and despite a similar screening detection process and lifestyle-related behaviour, it is constantly at a higher level than in metropolitan France. However, Caribbean populations that are genetically close to that of Martinique have generally much lower incidence of prostate cancer. We found no correlation between prostate cancer incidence rates, life expectancy, and diet westernization. Since the Caribbean African descent-associated genetic susceptibility factor would have remained constant during the 1980–2005, we suggest that in Martinique some environmental change including the intensive use of carcinogenic organochlorine pesticides might have occurred as key determinant of the persisting highly growing incidence of prostate cancer.

    Rates of out-of-hospital cardiac arrest (OHCA) and bystander cardiopulmonary resuscitation (CPR) have been shown to vary considerably in Victoria. We examined the extent to which this variation could be explained by the sociodemographic and population health characteristics of the region. Using the Victorian Ambulance Cardiac Arrest Registry, we extracted OHCA cases occurring between 2011 and 2013. We restricted the calculation of bystander CPR rates to those arrests that were witnessed by a bystander. To estimate the level of variation between Victorian local government areas (LGAs), we used a two-stage modelling approach using random-effects modelling. Between 2011 and 2013, there were 15 830 adult OHCA in Victoria. Incidence rates varied across the state between 41.9 to 104.0 cases/100 000 population. The proportion of the population over 65, socioeconomic status, smoking prevalence and education level were significant predictors of incidence in the multivariable model, explaining 93.9% of the variation in incidence among LGAs. Estimates of bystander CPR rates for bystander witnessed arrests varied from 62.7% to 73.2%. Only population density was a significant predictor of rates in a multivariable model, explaining 73% of the variation in the odds of receiving bystander CPR among LGAs. Our results show that the regional characteristics which underlie the variation seen in rates of bystander CPR may be region specific and may require study in smaller areas. However, characteristics associated with high incidence and low bystander CPR rates can be identified and will help to target regions and inform local interventions to increase bystander CPR rates.

    In this population-based study, we compared incident fracture rates in long-term care (LTC) versus community seniors between 2002 and 2012. Hip fracture rates declined more rapidly in LTC than in the community. An excess burden of fractures occurred in LTC for hip, pelvis, and humerus fractures in men and hip fractures only in women. This study compares trends in incident fracture rates between long-term care (LTC) and community-dwelling seniors ≥65 years, 2002-2012. This is a population-based cohort study using administrative data. Measurements were age/sex-adjusted incident fracture rates and rate ratios (RR) and annual percent change (APC). Over 11 years, hip fracture rates had a marked decline occurring more rapidly in LTC (APC, -3.49 (95% confidence interval (CI), -3.97, -3.01)) compared with the community (APC, -2.93 (95% CI, -3.28, -2.57); p < 0.05 for difference in slopes). Humerus and wrist fracture rates decreased; however, an opposite trend occurred for pelvis and spine fractures with rates increasing over time in both cohorts (all APCs, p < 0.05). In 2012, incident hip fracture rates were higher in LTC than the community (RRs: women, 1.55 (95% CI, 1.45, 1.67); men, 2.18 (95% CI, 1.93, 2.47)). Higher rates of pelvis (RR, 1.48 (95% CI, 1.22, 1.80)) and humerus (RR, 1.40 (95% CI, 1.07, 1.84)) fractures were observed in LTC men, not women. In women, wrist (RR, 0.76 (95% CI, 0.71, 0.81)) and spine (RR, 0.52 (95% CI, 0.45, 0.61)) fracture rates were lower in LTC than the community; in men, spine (RR, 0.75 (95% CI, 0.57, 0.98) but not wrist fracture (RR, 0.91 (95% CI, 0.67, 1.23)) rates were significantly lower in LTC than the community. Previous studies in the community have shown declining hip fracture rates over time, also demonstrated in our study but at a more rapid rate in LTC. Rates of humerus and wrist fractures also declined. An excess burden of fractures in LTC occurred for hip fractures in women and for hip, pelvis, and humerus fractures

    A genetic predisposition for certain tumour types has been proven for some dog breeds. Some studies have suggested that this may also be true for the Golden retriever breed. The present study aimed to examine a possible existence of a tumour (type) predisposition in the Dutch population of Golden retrievers by evaluating annual estimated incidence rates compared to incidence rates from previous publications. A second aim was to evaluate whether incidences of various tumours differed as related to the diagnostic method chosen, being either cytology or histology. Tumours submitted to Utrecht University during the period 1998-2004 diagnosed either by means of cytology (n = 2,529) or histology (n = 2,124), were related to an average annual Dutch kennel club population of 29,304 Golden retrievers.Combining individual tumours from both the cytological and the histopathological data-set resulted in an annual estimated incidence rate of 2,242 for 100,000 dog-years at risk regarding tumour development in general.The most common cytological tumor diagnoses were 'fat, possibly lipoma' (35%), mast cell tumour (21%) and non-Hodgkin lymphoma (10%). The most commonly diagnosed tumours by histology were mast cell tumour (26%), soft tissue sarcomas (11%) and melanoma (8%). Both the cytological and histopathological data-sets, showed variation; in patient age distribution, age of onset and incidence of various tumours. Comparing our data with previous reports in non-breed-specified dog populations, the Golden retriever breed shows an increased risk for the development of tumours in general, as well as an increased risk for the development of specific tumour types, including the group of soft tissue sarcomas. Variations in age, location and incidence of various tumours were observed between the two data-sets, indicating a selection bias for diagnostic procedure.

    2010-12-01

    Full Text Available Abstract Background High Human Immunodeficiency Virus (HIV prevalence and high risk behaviors have been well documented within United States (US correctional systems. However, uncertainty remains regarding the extent to which placing people in prison or jail increases their risk of HIV infection, and regarding which inmate populations experience an increased incidence of HIV. Describing these dynamics more clearly is essential to understanding how inmates and former detainees may be a source for further spread of HIV to the general US population. Methods The authors conducted a systematic review and meta-analysis of studies describing HIV incidence in US correctional facility residents and, for comparison, in high risk groups for HIV infection, such as non-incarcerated intravenous drug users (IVDU and men who have sex with men (MSM in the US. HIV incidence rates were further compared with Hepatitis B and Hepatitis C Virus rates in these same populations. Results Thirty-six predominantly prospective cohort studies were included. Across all infection outcomes, continuously incarcerated inmates and treatment recruited IVDU showed the lowest incidence, while MSM and street recruited IVDU showed the highest. HIV incidence was highest among inmates released and re-incarcerated. Possible sources of heterogeneity identified among HIV studies were risk population and race. Conclusions Although important literature gaps were found, current evidence suggests that policies and interventions for HIV prevention in correctional populations should prioritize curtailing risk of infection during the post-release period. Future research should evaluate HIV incidence rates in inmate populations, accounting for proportion of high risk sub-groups.

Therefore an attempt looking for an endemic area with a longtime biggest and smallest incidence rates in the smaller population scale, what a make easy fight against cancers. Materials and methods: In the years 1999–2009 20682 persons were diagnosed for RJG. Basing on the data (as above and demographic data, the different type of rates were calculated. All statistic procedures were in detail described anywhere [4–6]. Results: In the years 1999– 2009, in Silesia voivodeship, 20 682 cases of RJG were diagnosed, i.e. 53.5% among males and 46.5% among females. Age-adjusted rate for the whole Silesia voivodeship is 31.4 per 100 thousands to men and 19.5/100 thousands to women. In comparison between two extremely periods (1999–2009 : 2006–2009, age – adjusted incidence rates among men increased about 2.9%, and among women decreased about 6.5%. The distribution of age-standardized colorectal cancer rates within Silesia voivodeship, in the years 1999–2009, taking into account 36 counties – was very unequal so among males and at the same among females. But the most important epidemiological problem was the endemic areas with significantly biggest incidence rates among males: towns on the law of county: Częstochowa, Katowice, Bielsko-Biała and counties: mikołowski and wodzisławski; among females the endemic areas of this type were Bielsko-Biała town and his county.

    SUMMARY: The aim of this study was to estimate the incidence of hip fracture in Kermanshah, Iran. 161 cases (88 men and 73 women) were recorded. The annual age-standardized incidence rates were 181.1/100,000 in men and 214.6/100,000 in women. Incidence rate of hip fracture was less than in Western countries. INTRODUCTION: Hip fracture is the most serious complication of osteoporosis, the most common metabolic bone disease worldwide. The incidence of hip fracture in the elderly patients varies in different areas. The aim of this study was to estimate the incidence rate of hip fracture in Kermanshah, Iran. MATERIALS AND METHODS: All cases of hip fracture patients who aged 50 years or more admitted in six referral orthopedic hospitals in Kermanshah from May 21, 2007 to May 21, 2008 were studied. The age- and sex-specific incidence rates of hip fracture per 100,000 persons were calculated using the population data from the last national census in Iran, 2007. RESULTS: A total of 161 cases of hip fracture (88 men and 73 women) were recorded. The annual age-standardized incidence rates were 181.1/100,000 in men and 214.6/100,000 in women. The female to male ratio of hip fracture incidence was 1.18. CONCLUSION: We found a relatively low incidence of hip fracture in Iran than in Western countries, which is mostly due to the lower rate in women. This is probably related to the different lifestyle factors in different societies.

    Full Text Available Background. It remains unclear whether neighborhood poverty contributes to differences in subsite-specific colorectal cancer (CRC incidence. We examined associations between census-tract poverty and CRC incidence and stage by anatomic subsite and race/ethnicity. Methods. CRC cases diagnosed between 2005 and 2009 from 15 states and Los Angeles County (N=278,097 were assigned to 1 of 4 groups based on census-tract poverty. Age-adjusted and stage-specific CRC incidence rates (IRs and incidence rate ratios (IRRs were calculated. Analyses were stratified by subsite (proximal, distal, and rectum, sex, race/ethnicity, and poverty. Results. Compared to the lowest poverty areas, CRC IRs were significantly higher in the most impoverished areas for men (IRR = 1.14 95% CI 1.12–1.17 and women (IRR = 1.06 95% CI 1.05–1.08. Rate differences between high and low poverty were strongest for distal colon (male IRR = 1.24 95% CI 1.20–1.28; female IRR = 1.14 95% CI 1.10–1.18 and weakest for proximal colon. These rate differences were significant for non-Hispanic whites and blacks and for Asian/Pacific Islander men. Inverse associations between poverty and IRs of all CRC and proximal colon were found for Hispanics. Late-to-early stage CRC IRRs increased monotonically with increasing poverty for all race/ethnicity groups. Conclusion. There are differences in subsite-specific CRC incidence by poverty, but associations were moderated by race/ethnicity.

Methods: A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results: A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0, followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0, and the eastern region, at 9.9 times (95% CI: 5.6–17.6. The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion: There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease.

    Recent studies compared the age effects and birth cohort effects on female invasive breast cancer (FIBC) incidence in Asian populations with those in the US white population. They were based on age-period-cohort model extrapolation and estimated annual percentage change (EAPC) in the age-standardized incidence rates (ASR). It is of interest to examine these results based on cohort-specific annual percentage change in rate (APCR) by age and without age-period-cohort model extrapolation. FIBC data (1991-2010) were obtained from the Taiwan Cancer Registry and the U.S. SEER 9 registries. APCR based on smoothed Lexis diagrams were constructed to study the age, period, and cohort effects on FIBC incidence. The patterns of age-specific rates by birth cohort are similar between Taiwan and the US. Given any age-at-diagnosis group, cohort-specific rates increased overtime in Taiwan but not in the US; cohort-specific APCR by age decreased with birth year in both Taiwan and the US but was always positive and large in Taiwan. Given a diagnosis year, APCR decreased as birth year increased in Taiwan but not in the US. In Taiwan, the proportion of APCR attributable to cohort effect was substantial and that due to case ascertainment was becoming smaller. Although our study shows that incidence rates of FIBC have increased rapidly in Taiwan, thereby confirming previous results, the rate of increase over time is slowing. Continued monitoring of APCR and further investigation of the cause of the APCR decrease in Taiwan are warranted. © 2017 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

    The aim of this study was to examine the predictive value of serum cystatin C (CysC) and that of creatinine-based estimated glomerular filtration rate (eGFRCreat) for the risk of incident hypertension in a middle-aged male population. Serum CysC levels were measured in 904 nonhypertensive, Japanese male subjects (mean age = 44±6 years) who received an annual general health examination in a company. Serum creatinine levels were simultaneously measured, and eGFRCreat was calculated. Subjects were followed-up for a maximum period of 4 years, and annual blood pressure measurements were recorded. During the follow-up period, 124 subjects developed hypertension, defined as systolic/diastolic blood pressure ≥140/90 mmHg or use of antihypertensive medications. In the Kaplan-Meier analysis, both the third quintile of CysC and that of eGFRCreat showed the lowest 4-year cumulative incident rate of hypertension. The multiadjusted hazard ratio for incident hypertension was significantly increased in the highest quintile of CysC compared with the third quintile (2.60; 95% confidence interval (CI) = 1.41-4.77; P = 0.002), as well as compared with the lowest 4 quintiles combined (1.89; 95% CI = 1.26-2.84; P = 0.002). However, eGFRCreat did not show significant hazard ratios for incident hypertension in any of the adjusted models. Elevated serum CysC levels could predict the risk of incident hypertension in this study population with a maximum follow-up period of 4 years. In contrast, eGFRCreat did not show predictive value for the risk of incident hypertension.

    Several Clostridium difficile infection (CDI) surveillance programs do not specify laboratory strategies to use. We investigated the evolution in testing strategies used across Quebec, Canada, and its association with incidence rates. Cross-sectional study of 95 hospitals by surveys conducted in 2010 and in 2013-2014. The association between testing strategies and institutional CDI incidence rates was analyzed via multivariate Poisson regressions. The most common assays in 2014 were toxin A/B enzyme immunoassays (EIAs) (61 institutions, 64%), glutamate dehydrogenase (GDH) EIAs (51 institutions, 53.7%), and nucleic acid amplification tests (NAATs) (34 institutions, 35.8%). The most frequent algorithm was a single-step NAAT (20 institutions, 21%). Between 2010 and 2014, 35 institutions (37%) modified their algorithm. Institutions detecting toxigenic C difficile instead of C difficile toxin increased from 14 to 37 (P < .001). Institutions detecting toxigenic C difficile had higher CDI rates (7.9 vs 6.6 per 10,000 patient days; P = .01). Institutions using single-step NAATs, GDH plus toxigenic cultures, and GDH plus cytotoxicity assays had higher CDI rates than those using an EIA-based algorithm (P < .05). Laboratory detection of CDI has changed since 2010. There is an association between diagnostic algorithms and CDI incidence. Mitigation strategies are warranted.

    The effectiveness of continuous nationwide surveillance on healthcare-associated infections should be investigated in each country. To assess the rate of device-associated infections (DAIs) in intensive care units (ICUs) since the establishment of the Korean Nosocomial Infections Surveillance System (KONIS). Nationwide data were obtained on the incidence rate of DAI in ICUs reported to KONIS by all participating hospitals. The three major DAIs were studied: ventilator-associated pneumonia (VAP), central line-associated bloodstream infection (CABSI), and catheter-associated urinary tract infection (CAUTI). The pooled and year-wise incidence rates (cases per 1000 device-days) of these DAIs were determined for the period 2006 and 2012. In addition, data from institutions that had participated in KONIS for at least three consecutive years were analysed separately. The number of ICUs participating in KONIS gradually increased from 76 in 2006 to 162 in 2012. Between 2006 and 2012, the incidence rate per 1000 device-days for VAP decreased significantly from 3.48 to 1.64 (F = 11, P Infection Society. Published by Elsevier Ltd. All rights reserved.

    Pulmonary embolism (PE) is a life-threatening condition common after major surgery. Although the high incidence (0.3-30%) and mortality rate (16.9-31%) of PE in patients undergoing major surgical procedures is apparent from findings of contemporary observational studies, there is a lack of a summary and meta-analysis data on the epidemiology of postoperative PE in this same regard. Hence, we propose to conduct the first systematic review to summarise existing data on the global incidence, determinants and case fatality rate of PE following major surgery. Electronic databases including MEDLINE, EMBASE, SCOPUS, WHO global health library (including LILACS), Web of Science and Google scholar from inception to April 30, 2017, will be searched for cohort studies reporting on the incidence, determinants and case fatality rate of PE occurring after major surgery. Data from grey literature will also be assessed. Two investigators will independently perform study selection and data extraction. Included studies will be evaluated for risk of bias. Appropriate meta-analytic methods will be used to pool incidence and case fatality rate estimates from studies with identical features, globally and by subgroups of major surgical procedures. Random-effects and risk ratio with 95% confidence interval will be used to summarise determinants and predictors of mortality of PE in patients undergoing major surgery. This systematic review and meta-analysis will provide the most up-to-date epidemiology of PE in patients undergoing major surgery to inform health authorities and identify further research topics based on the remaining knowledge gaps.

    Cutaneous malignancy is associated with worse outcomes in patients with chronic lymphocytic leukemia (CLL). We sought to identify the incidence and recurrence rate of nonmelanoma skin cancer (NMSC) in patients with non-Hodgkin lymphoma (NHL). NMSC incidence was calculated and Cox proportional hazards models were used to evaluate associations with risk of recurrence for patients with NHL between 1976 and 2005 who were in the Rochester Epidemiology Project research infrastructure. We identified 282 patients with CLL or small lymphocytic lymphoma and 435 with non-CLL NHL. The incidence of basal cell carcinoma and squamous cell carcinoma was 1829.3 (95% confidence interval [CI] 1306.7-2491.1) and 2224.9 (95% CI 1645.9-2941.6), respectively, in patients with CLL. The cumulative recurrence rate at 8 years after treatment with Mohs micrographic surgery was 8.3% (95% CI 0.0%-22.7%) for basal cell carcinoma and 13.4% (95% CI 0.0%-25.5%) for squamous cell carcinoma in patients with CLL. This was a retrospective cohort study. After Mohs micrographic surgery and standard excision of NMSC, patients with NHL had a skin cancer recurrence rate that was higher than expected. Careful treatment and monitoring of patients with NHL and NMSC are warranted. Copyright © 2014 American Academy of Dermatology, Inc. Published by Elsevier Inc. All rights reserved.

    Background The present study reviews the epidemiological data on corpus uteri cancer among Saudi women, including its frequency, crude incidence rate, and age-standardized incidence rate (ASIR), adjusted by region and year of diagnosis. Methods A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0), followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0), and the eastern region, at 9.9 times (95% CI: 5.6–17.6). The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease. Riyadh, the eastern region, and Makkah had the highest overall disease ASIRs and incidence rate ratios, while Jazan, Najran, and Qassim had the lowest rates. Finally, the northern region experienced the greatest changes in ASIR during the studied period. Further analytical studies are necessary to determine potential risk factors of corpus uteri cancer among female Saudi

    Background This study describes epidemiological data of non-Hodgkin’s lymphoma (NHL) diagnosed from 2001 to 2008 among Saudi men. Materials and methods Retrospective data from all NHL cancer cases among Saudi men recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008 were used. Descriptive statistics, analysis of variance, Poisson regression, and simple linear regression were also used. Results In total, 2,555 new cases of NHL were recorded between January 2001 and December 2008. The region of Riyadh, Saudi Arabia had the highest overall age-standardized incidence rate (ASIR) at 7.8, followed by the Eastern region at 6.8, and Makkah at 6.1 per 100,000 men; however, Jazan, Hail, and Baha had the lowest average ASIRs at 2.5, 3.7, and 3.9 per 100,000 men, respectively. The incidence-rate ratio for the number of NHL cases was significantly higher in Riyadh (4.68, 95% confidence interval [CI] 4.11–5.32), followed by Makkah (4.47, 95% CI 3.94–5.07), and the Eastern region of Saudi Arabia (3.27, 95% CI 2.90–3.69) than that in the reference region of Jazan. Jouf had the highest changes in the ASIRs of NHL among Saudi men from 2001 and 2008 (5.0 per 100,000 men). Conclusion A significant increase in the crude incidence rate and ASIR for NHL in Saudi Arabia between 2001 and 2008 was found. Riyadh, the Eastern region, and Makkah had the highest overall ASIR in Saudi Arabia. Jazan, Hail, and Baha had the lowest rates. Additionally, Riyadh, Makkah, and the Eastern region had the highest incidence-rate ratio for the number of NHL cases. Finally, Jouf had the highest changes in crude incidence rate and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of NHL among Saudi men.

    This study aimed to examine long-term population-based trends in the incidence rate of patients with a humeral fracture admitted to a hospital in the Netherlands from 1986 to 2012 and to give a detailed overview of the health care consumption and productivity loss with associated costs. Age and gender-standardised incidence rates of hospital admissions for patients with a proximal, shaft, or distal humeral fracture were calculated for each year (1986-2012). Injury cases, length of hospital stay (LOS), trauma mechanism, and operation rate were extracted from the National Medical Registration. An incidence-based cost model was applied to calculate costs for direct health care and lost productivity in 2012. Between 1986 and 2012 112,910 patients were admitted for a humeral fracture. The incidence rate increased from 17.8 in 1986 to 40.0 per 100,000 person years in 2012. Incidence rates of proximal fractures increased the most, especially in elderly women. Operation rates decreased in patients aged 70 years or older. The mean LOS decreased from nine days in 1997 to five days in 2012. The cumulative LOS of all patients in 2012 was 28,880 days of which 73% were caused by women and 81% were caused by patients aged 50 years or older. Cumulative medical costs in 2012 were M€55.4, of which M€43.4 was spent on women. Costs increased with age. Costs for hospital care contributed most to the overall costs per case until 70 years of age. From 70 years onwards, the main cost determinants were hospital care, rehabilitation/nursing care, and home care. Cumulative costs due to lost productivity were M€23.5 in 2012. Costs per case increased with age in all anatomic regions. The crude number of patients admitted for a humeral fracture increased 124% in 27 years, and was associated with age and gender. Proximal fractures in elderly women accounted most significantly for this increase and most of the costs. The main cost determinants were hospital care and productivity loss

    To evaluate whether a country's Human Development Index (HDI) can help explain the differences in the country's breast cancer and gynecological cancer incidence and mortality rates in the Pan-American region. Ecological analysis. Pan-American region countries with publicly available data both in GLOBOCAN 2012 and the United Nations Development Report 2012 were included (n = 28). Incidence and mortality rates age-standardized per 100,000 were natural log-transformed for breast cancer, ovarian cancer, corpus uteri cancer, and cervical cancer. The mortality-to-incidence ratio (MIR) was calculated for each site. Pearson's correlation test and a simple linear regression were performed. The HDI showed a positive correlation with breast cancer and ovarian cancer incidence and mortality rates, respectively, and a negative correlation with cervical cancer incidence and mortality rates. The HDI and corpus uteri cancer showed no association. MIR and the HDI showed a negative correlation for all tumor types except ovarian cancer. An increment in 1 HDI unit leads to changes in cancer rates: in breast cancer incidence β = 4.03 (95% confidence interval [CI] 2.61; 5.45) P < 0.001, breast cancer mortality β = 1.76 (95% CI 0.32; 3.21) P = 0.019, and breast cancer-MIR β = -0.705 (95% CI 0.704; 0.706) P < 0.001; in cervical cancer incidence β = -3.28 (95% CI -4.78; -1.78) P < 0.001, cervical cancer mortality β = -4.63 (95% CI -6.10; -3.17) P < 0.001, and cervical cancer-MIR β = -1.35 (95% CI -1.83; -0.87) P < 0.001; in ovarian cancer incidence β = 3.26 (95% CI 1.78; 4.75) P < 0.001, ovarian cancer mortality β = 1.82 (95% CI 0.44; 3.20) P = 0.012, and ovarian cancer-MIR β = 5.10 (95% CI 3.22; 6.97) P < 0.001; in corpus uteri cancer incidence β = 2.37 (95% CI -0.33; 5.06) P = 0.83, corpus uteri cancer mortality β = 0.68 (95% CI -2.68; 2.82) P = 0.96, and corpus uteri cancer-MIR β = -2.30 (95% CI -3.19; -1.40) P < 0.001.

    Purpose: To compare the second malignancy incidence in prostate cancer patients treated with brachytherapy (BT) relative to radical prostatectomy (RP) and to compare both groups with the cancer incidence in the general population. Methods and Materials: From 1998 to 2010, 2418 patients were treated with Iodine 125 prostate BT monotherapy at the British Columbia Cancer Agency, and 4015 referred patients were treated with RP. Cancer incidence was compared with the age-matched general population using standardized incidence ratios (SIRs). Pelvic malignancies included invasive and noninvasive bladder cancer and rectal cancer. Cox multivariable analysis was performed with adjustment for covariates to determine whether treatment (RP vs BT) was associated with second malignancy risk. Results: The median age at BT was 66 years and at RP 62 years. The SIR comparing BT patients with the general population was 1.06 (95% confidence interval [CI] 0.91-1.22) for second malignancy and was 1.53 (95% CI 1.12-2.04) for pelvic malignancy. The SIR comparing RP patients with the general population was 1.11 (95% CI 0.98-1.25) for second malignancy and was 1.11 (95% CI 0.82-1.48) for pelvic malignancy. On multivariable analysis, older age (hazard ratio [HR] 1.05) and smoking (HR 1.65) were associated with increased second malignancy risk (P<.0001). Radical prostatectomy was not associated with a decreased second malignancy risk relative to BT (HR 0.90, P=.43), even when excluding patients who received postprostatectomy external beam radiation therapy (HR 1.13, P=.25). Older age (HR 1.09, P<.0001) and smoking (HR 2.17, P=.0009) were associated with increased pelvic malignancy risk. Radical prostatectomy was not associated with a decreased pelvic malignancy risk compared with BT (HR 0.57, P=.082), even when excluding postprostatectomy external beam radiation therapy patients (HR 0.87, P=.56). Conclusions: After adjustment for covariates, BT patients did not have an increased second

    The purpose of this study was to estimate the 6-month incidence rates of sexual assault, physical dating violence (DV), and unwanted pursuit (e.g., stalking) victimization among sexual-minority (i.e., individuals with any same-sex sexual experiences) college students with comparison data from non-sexual-minority (i.e., individuals with only heterosexual sexual experiences) college students. Participants (N = 6,030) were primarily Caucasian (92.7%) and non-sexual-minority (82.3%). Compared with non-sexual-minority students (N-SMS; n = 4,961), sexual-minority students (SMS; n = 1,069) reported significantly higher 6-month incidence rates of physical DV (SMS: 30.3%; N-SMS: 18.5%), sexual assault (SMS: 24.3%; N-SMS: 11.0%), and unwanted pursuit (SMS: 53.1%; N-SMS: 36.0%) victimization. We also explored the moderating role of gender and found that female SMS reported significantly higher rates of physical DV than female N-SMS, whereas male SMS and male N-SMS reported similar rates of physical DV. Gender did not moderate the relationship between sexual-minority status and victimization experiences for either unwanted pursuit or sexual victimization. These findings underscore the alarmingly high rates of interpersonal victimization among SMS and the critical need for research to better understand the explanatory factors that place SMS at increased risk for interpersonal victimization. © The Author(s) 2014.

    Depression may potentially impair the clinical course of Alzheimer's disease (AD). Thus, the aim of this study was to investigate cognitive progression of AD patients with or without major depressive episode (MDE). In this 1-year longitudinal follow-up study conducted in three Italian memory clinics, 119 newly diagnosed probable AD patients of mild severity, who were not undergoing treatment with an acetyl-cholinesterase inhibitor (AChEI), and had not been treated with psychotropic drugs in the last 2 years, were included. Patients were assessed to investigate the effect of baseline and 1-year follow-up MDE (using modified DSM-IV diagnostic criteria for MDE in AD) on progression of global cognitive deterioration (using Mini-Mental State Examination (MMSE)), adjusted for confounding factors. Never being depressed was associated with a 3.1 (95%CI 1.0-10.1) increased risk of MMSE decline compared to recovered depression. Six times more patients with persistent depression had MMSE decline compared to patients with recovered depression. However, the largest odds (7.3; 95%CI 1.4-38.1) of cognitive decline was observed in patients who developed incident depression over follow-up. In conclusion, persistent or incident depression worsens cognitive outcome while no or recovered depression does not affect it in early AD patients. Copyright © 2012 Elsevier Ltd.

    Elite-level professional soccer players are suggested to have increased physical, technical, tactical, and psychological capabilities when compared with their subelite counterparts. Ensuring these players remain at the elite level generally involves training many different bodily systems to a high intensity or level within a short duration. This study aimed to examine whether an increase in training volume at high-intensity levels was related to injury incidence, or increased the odds of sustaining an injury. Training intensity was monitored through time spent in high-intensity (T-HI) and very high-intensity (T-VHI) zones of 85-training volume at T-HI and injury incidence (r = 0.57, p = 0.005). Further analysis revealed how players achieving more time in the T-VHI zone during training increased the odds of sustaining a match injury (odds ratio = 1.87; 95% CI, 1.12-3.12, p = 0.02) but did not increase the odds of sustaining a training injury. Reducing the number of competitive match injuries among elite-level professional players may be possible if greater focus is placed on the training intensity and volume over a period of time ensuring the potential reduction of fatigue or overuse injuries. In addition, it is important to understand the optimal training load at which adaptation occurs without raising the risk of injury.

  5. Apparently-Different Clearance Rates from Cohort Studies of Mycoplasma genitalium Are Consistent after Accounting for Incidence of Infection, Recurrent Infection, and Study Design.

    Full Text Available Mycoplasma genitalium is a potentially major cause of urethritis, cervicitis, pelvic inflammatory disease, infertility, and increased HIV risk. A better understanding of its natural history is crucial to informing control policy. Two extensive cohort studies (students in London, UK; Ugandan sex workers suggest very different clearance rates; we aimed to understand the reasons and obtain improved estimates by making maximal use of the data from the studies. As M. genitalium is a sexually-transmitted infectious disease, we developed a model for time-to-event analysis that incorporates the processes of (reinfection and clearance, and fitted to data from the two cohort studies to estimate incidence and clearance rates under different scenarios of sexual partnership dynamics and study design (including sample handling and associated test sensitivity. In the London students, the estimated clearance rate is 0.80 p.a. (mean duration 15 months, with incidence 1.31%-3.93% p.a. Without adjusting for study design, corresponding estimates from the Ugandan data are 3.44 p.a. (mean duration 3.5 months and 58% p.a. Apparent differences in clearance rates are probably mostly due to lower testing sensitivity in the Uganda study due to differences in sample handling, with 'true' clearance rates being similar, and adjusted incidence in Uganda being 28% p.a. Some differences are perhaps due to the sex workers having more-frequent antibiotic treatment, whilst reinfection within ongoing sexual partnerships might have caused some of the apparently-persistent infection in the London students. More information on partnership dynamics would inform more accurate estimates of natural-history parameters. Detailed studies in men are also required.

    Nonoperative management (NOM) for blunt splenic injury (BSI) is well-established. Angiography (ANGIO) has been shown to improve success rates with NOM. Protocols for NOM are not standardized and vary widely between centers. We hypothesized that trauma centers that performed ANGIO at a greater rate would demonstrate decreased rates of splenectomy compared with trauma centers that used ANGIO less frequently. A large, multicenter, statewide database (Pennsylvania Trauma Systems Foundation) from 2007 to 2011 was used to generate the study cohort of patients with BSI (age ≥ 13). The cohort was divided into 2 populations based on admission to centers with high (≥13%) or low (Splenectomy rates were then compared between the 2 groups, and multivariable logistic regression for predictors of splenectomy (failed NOM) were also performed. The overall rate of splenectomy in the entire cohort was 21.0% (1,120 of 5,333 BSI patients). The high ANGIO group had a lesser rate of splenectoy compared with the low ANGIO group (19% vs 24%; P splenectomy compared with low ANGIO centers (odds ratio, 0.68; 95% CI 0.58-0.80; P splenectomy rates compared with centers with lesser rate of ANGIO. Inclusion of angiographic protocols for NOM of BSI should be considered strongly. Copyright © 2015 Elsevier Inc. All rights reserved.

    Full Text Available Background. This study was undertaken to evaluate trends in breast cancer incidence in Egypt from 1999 to 2008 and to make projections for breast cancer occurrence for the years 2009–2015. Patients and Methods. We utilized joinpoint regression and average annual percent change (AAPC measures with 95% confidence intervals (CI to describe the trends in breast cancer incidence rates from the Gharbiah Cancer Registry by age and stage at diagnosis and to estimate expected breast cancer caseloads for 2009–2015. Results. From 1999 to 2008, the AAPC in breast cancer incidence rates in Gharbiah significantly increased among women 50 years and older and among localized tumors (AAPC %, 95% CI, 3.1% to 8.0%. Our results predict a significant increase in breast cancer caseloads from 2009 to 2015 among women aged 30–39 (AAPC %, 95% CI, 0.9% to 1.1% and among women aged 40–49 years (AAPC %, 95% CI, 1.0% to 2.6%. Conclusion. These results have important implications for allocating limited resources, managing treatment needs, and exploring the consequences of prior interventions and/or changing risk factors in Egypt and other developing countries at the same stages of demographic and health transitions.

    A preliminary study revealed significantly lower serum iron concentrations in lambs that developed abomasal bloat about one week later, than in lambs that did not develop bloat. In a subsequent trial, with 754 naturally reared twin lambs from five flocks, iron dextran injections were found to have a preventive effect on the development of abomasal bloat. Clinical signs of abomasal bloat were observed in the placebo-treated lamb of 16 couples and in the iron-treated lamb of six couples (Piron-treated group had significantly (Piron saturation in the placebo group 14 days after treatment but not in the iron-treated lambs. In one of the flocks, there was a decrease in the cumulative incidence of abomasal bloat from 37 per cent to 3 per cent during the period of four years after measures such as later lambing, earlier turnout and iron injections were introduced.

    Emilia Romagna, a northern Italian region, has a population of 4.27 million, of which 9.7% are immigrants. The objective of this study was to investigate the epidemiology of tuberculosis (TB) during the period 1996-2006 in not Italy-born compared to Italy-born cases. Data was obtained from the Regional TB surveillance system, from where personal data, clinical features and risk factors of all notified TB cases were extracted. 5377 TB cases were reported. The proportion of immigrants with TB, over the total number of TB cases had progressively increased over the years, from 19.1% to 53.3%. In the not Italy-born population, TB incidence was higher than in Italians (in 2006: 100.7 cases per 100,000 registered not Italy-born subjects and 83.9/100,000 adding 20% of estimated irregular presences to the denominators. TB incidence among Italians was 6.5/100,000 Italians). A progressive rise in the not Italy-born incident cases was observed but associated with a decline in TB incidence. Not Italy-born cases were younger compared to the Italy-born cases, and more frequently classified as "new cases" (OR 2.0 95%CI 1.61-2.49 for age group 20-39); 60.7% had pulmonary TB, 31.6% extra pulmonary and 7.6% disseminated TB. Risk factors for TB in this population group were connected to lower income status (homeless: OR 149.9 95%CI 20.7-1083.3 for age group 40-59). In low-incidence regions, prevention and control of TB among sub-groups at risk such as the foreign-born population is a matter of public health concern. In addition, increasing immigration rates may affect TB epidemiology. TB among immigrants is characterized by particular clinical features and risk factors, which should be analyzed in order to plan effective action.

    The objective of this observational study was to determine the association of exposure to selected bedding types with incidence of subclinical (SM) and clinical mastitis (CM) in primiparous Holstein dairy cows housed in identical pens at a single facility. At parturition, primiparous cows were randomly assigned to pens containing freestalls with 1 of 4 bedding materials: (1) deep-bedded new sand (NES, n=27 cows), (2) deep-bedded recycled sand (RS, n=25 cows), (3) deep-bedded manure solids (DBMS, n=31 cows), and (4) shallow-bedded manure solids over foam-core mattresses (SBMS, n=26 cows). For 12mo, somatic cell counts of quarter milk samples were determined every 28d and duplicate quarter milk samples were collected for microbiological analysis from all quarters with SM (defined as somatic cell count >200,000 cells/mL). During this period, duplicate quarter milk samples were also collected for microbial analysis from all cases of CM. For an additional 16mo, cases of CM were recorded; however, no samples were collected. Quarter days at risk (62,980) were distributed among bedding types and most quarters were enrolled for >150d. Of 135 cases of SM, 63% resulted in nonsignificant growth and 87% of recovered pathogens (n=33) were identified as coagulase-negative staphylococci. The distribution of etiologies of pathogens recovered from cases of SM was associated with bedding type. Coagulase-negative staphylococci were recovered from 12, 38, 11, and 46% of quarters with SM from cows in pens containing NES, RS, DBMS, and SBMS, respectively. A result of nonsignificant growth was obtained for 81, 59, 89, and 46% of quarters with SM from cows in pens containing NES, RS, DBMS, and SBMS, respectively. Quarters of primiparous cows bedded with NES tended to have greater survival time to incidence of CM than quarters of primiparous cows bedded with RS or DBMS.

    Purpose This study provides descriptive epidemiological data, such as the percentage of cases diagnosed, crude incidence rate (CIR), and age-standardized incidence rate (ASIR) of ovarian cancer in Saudi Arabia from 2001–2008. Patients and methods A retrospective descriptive epidemiological analysis of all ovarian cancer cases recorded in the Saudi Cancer Registry (SCR) from January 2001–December 2008 was performed. The data were analyzed using descriptive statistics, analysis of variance tests, Poisson regression, and simple linear modeling. Results A total of 991 ovarian cancer cases were recorded in the SCR from January 2001–December 2008. The region of Riyadh had the highest overall ASIR at 3.3 cases per 100,000 women, followed by the Jouf and Asir regions at 3.13 and 2.96 cases per 100,000 women. However, Hail and Jazan had the lowest rates at 1.4 and 0.6 cases per 100,000 women, respectively. Compared to Jazan, the incidence rate ratio for the number of ovarian cancer cases was significantly higher (P<0.001) in the Makkah region at 6.4 (95% confidence interval [CI]: 4.13–9.83), followed by Riyadh at 6.3 (95% CI: 4.10–9.82), and the eastern region of Saudi Arabia at 4.52 (95% CI: 2.93–6.98). The predicted annual CIR and ASIR for ovarian cancer in Saudi Arabia could be defined by the equations 0.9 + (0.07× years) and 1.71 + (0.09× years), respectively. Conclusion We observed a slight increase in the CIRs and ASIRs for ovarian cancer in Saudi Arabia from 2001–2008. Riyadh, Jouf, and Asir had the highest overall ASIR, while Jazan and Hail had the lowest rates. Makkah, Riyadh, and the eastern region of Saudi Arabia had the highest incidence rate ratio for the number of ovarian cancer cases. Further analytical studies are required to determine the potential risk factors of ovarian cancer among Saudi women. PMID:25028565

    This study investigated the comparative effects of reduced irrigation regimes—partial root-zone drying (PRD) and conventional deficit irrigation (DI)—on the incidence of blossom-end rot (BER) in tomato (Solanum lycopersicum L.) under three Ca-fertilization rates: 0, 100, and 200mg Ca kg–1 soil...... (denoted Ca0, Ca1, and Ca2, respectively). The plants were grown in split-root pots in a climate-controlled glasshouse and treated with PRD and DI during early flowering to the fruit maturity stage. The results showed that, in comparison with DI treatment, PRD significantly reduced BER incidence. A greater...... xylem sap abscisic acid concentration, lower stomatal conductance, and higher plant water status in the PRD in relation to the DI plants might have contributed to the increased fruit Ca uptake, and could have reduced BER development in tomato fruits. Therefore, under conditions with limited freshwater...

    2015-03-17

    Bilateral Wilms tumours (BWTs) occur by germline mutation of various predisposing genes; one of which is WT1 whose abnormality was reported in 17-38% of BWTs in Caucasians, whereas no such studies have been conducted in East-Asians. Carriers with WT1 mutations are increasing because of improved survival. Statuses of WT1 and IGF2 were examined in 45 BWTs from 31 patients with WT1 sequencing and SNP array-based genomic analyses. The penetrance rates were estimated in WT1-mutant familial Wilms tumours collected from the present and previous studies. We detected WT1 abnormalities in 25 (81%) of 31 patients and two families, which were included in the penetrance rate analysis of familial Wilms tumour. Of 35 BWTs from the 25 patients, 31 had small homozygous WT1 mutations and uniparental disomy of IGF2, while 4 had large 11p13 deletions with the retention of 11p heterozygosity. The penetrance rate was 100% if children inherited small WT1 mutations from their fathers, and 67% if inherited the mutations from their mothers, or inherited or had de novo 11p13 deletions irrespective of parental origin (P=0.057). The high incidence of WT1 abnormalities in Japanese BWTs sharply contrasts with the lower incidence in Caucasian counterparts, and the penetrance rates should be clarified for genetic counselling of survivors with WT1 mutations.

    Paramedic services are considering moving towards the use of powered stretcher and load systems to reduce stretcher related injuries, but cost is perceived as a barrier. This study compared injury incidence rates, days lost, and compensation costs between Niagara Emergency Medical Service (NEMS) and Hamilton Paramedic Service (HPS) pre- (four years) and post- (one year) implementation of powered stretcher and load systems in NEMS. Prior to the intervention stretcher related musculoskeletal disorder (MSD) incidence rates averaged 20.0 (±6.8) and 17.9 (±6.4) per 100 full time equivalent (FTE), in NEMS and HPS respectively. One-year post intervention rates decreased to 4.3 per 100 FTE in NEMS, a 78% reduction. Rates modestly increased to 24.6 per 100 FTE in HPS in same period. Cost-benefit analysis estimated that the added cost to purchase powered stretcher and load systems would be recovered within their expected 7-year service life due to the reduction in compensation costs.

  15. Trends in overall opportunistic illnesses, Pneumocystis carinii pneumonia, cerebral toxoplasmosis andMycobacterium avium complex incidence rates over the 30 years of the HIV epidemic: a systematic review

    Directory of Open Access Journals (Sweden)

    Lara Coelho

    Full Text Available BACKGROUND: The natural history of HIV infection has changed dramatically after the introduction of highly active antiretroviral therapy. Currently, opportunistic illnesses still represent a major cause of death and hospitalization in this population. In this study, we review the trends in opportunistic illnesses incidence rates and compare the results observed in high-income settings with that for low/middle-income settings, with special attention given to studies from Brazil. METHODS: We systematically searched Pubmed, Web of Science, Lilacs and Google scholar for publications on HIV associated opportunistic illness. Studies reporting rates based on person-time for all opportunistic illnesses and/or the three opportunistic infections of interest, namely,Pneumocystis carinii pneumonia, cerebral toxoplasmosis, and Mycobacterium avium complex were included. RESULTS: Significant reductions in the incidence rates were demonstrated for opportunistic illnesses overall and also for the specific opportunistic infections included in the present study, both in high and low/middle-income settings. Out of the 37 studies included in the present review, almost 70% were from high-income settings. All the studies conducted in low/middle-income settings were single center studies and four were from Brazil. We found no study from Brazil reporting annual incidence rates of opportunistic illnesses. CONCLUSIONS: Opportunistic illnesses remain an important public health problem. To better guide health policies in low/middle-income settings, multicenter cohort studies should be encouraged. Studies from Brazil are urgently needed to assess the current burden of opportunistic illnesses in our population and to support the planning of HIV/AIDS health care services organization.

    Few contemporary data are available that compare incidence and survival of metastatic breast cancer between ductal and lobular carcinomas. Using the Surveillance, Epidemiology, and End Results-9 registries, we identified 10,639 patients with de novo metastatic breast cancer diagnosed from 1990 to 2011. Annual age-adjusted incidence rates and annual percent changes (APCs) were analyzed. Multivariable Cox regression models were used to investigate the impact of year of diagnosis and histology on overall survival. 9250 (86.9 %) patients had ductal and 1389 (13.1 %) had lobular carcinomas. Metastatic breast cancer incidence increased slightly over time for ductal (APC = +1.7, 95 % confidence interval (CI) = +1.0 to +2.4) and lobular carcinomas (APC = +3.0, 95 % CI = +1.8 to +4.3). Median overall survival was 22 months among the whole cohort. More recent year of diagnosis was associated with better overall survival only for patients with ductal carcinomas (interaction p value = 0.006), with an adjusted hazard ratio of death for every five-year increment in the date of diagnosis of 0.93 (95 % CI =  0.91-0.95) among ductal carcinomas, compared with 1.05 (95 % CI = 0.95-1.10) among lobular carcinomas. Overall survival was longer for lobular versus ductal carcinomas (28 versus 21 months, respectively; adjusted hazard ratio of death = 0.93, 95 % CI = 0.87-0.99), but the magnitude of this effect was attenuated among the cohort restricted to hormone receptor-positive tumors. In this population-based analysis, incidence rates of metastatic breast cancer at presentation increased slightly over time for both histologies, and particularly for lobular tumors. A modest improvement in metastatic breast cancer median overall survival was observed, but was apparently limited to ductal carcinomas.

    Harrison, F.L.; Rice, D.W. Jr.

    1981-10-13

    The usefulness of sister chromatid exchange (SCE) induction as a measure of low-level radiation effect was examined in a benthic marine worm, Neanthes arenaceodentata. Larvae were exposed to /sup 60/Co radiation for 12 to 24 h at total doses ranging from 0.5 to 309 R and at dose rates from 0.04 to 13 R/h. Animals exposed at intermediate dose rates (0.5, 0.6, 1.25, 2.0, and 2.5 R/h) had SCE frequencies per chromosome about twice that of those receiving no radiation (controls), whereas those exposed at the higher dose rates (7.0 and 13 R/h) had SCE frequencies lower than the controls. Animals exposed at the lower dose rates (0.04 and 0.1 R/h) had lower SCE frequencies than those exposed at intermediate dose rates (and higher SCE frequencies than controls). The length of chromosome pair number one differed among metaphase spreads and was used as an index of chromosome condensation in a given metaphase. Because there is a possibility that chromosome morphology may affect the ability to resolve SCEs, morphology will be monitored in future studies. A preliminary experiment was performed to assess the effects of 2.2 and 11.5 R/h for 24 h on growth and development. Larvae observed at 6 and 17 d after irradiation did not have significantly different numbers of abnormal larvae or survival rates.

    Prostate cancer (PCa) is a leading cause of mortality and morbidity globally, but its specific geographic patterns and temporal trends are under-researched. To test the hypotheses that PCa incidence is higher and PCa mortality is lower in countries with higher socioeconomic development, and that temporal trends for PCa incidence have increased while mortality has decreased over time. Data on age-standardized incidence and mortality rates in 2012 were retrieved from the GLOBOCAN database. Temporal patterns were assessed for 36 countries using data obtained from Cancer incidence in five continents volumes I-X and the World Health Organization mortality database. Correlations between incidence or mortality rates and socioeconomic indicators (human development index [HDI] and gross domestic product [GDP]) were evaluated. The average annual percent change in PCa incidence and mortality in the most recent 10 yr according to join-point regression. Reported PCa incidence rates varied more than 25-fold worldwide in 2012, with the highest incidence rates observed in Micronesia/Polynesia, the USA, and European countries. Mortality rates paralleled the incidence rates except for Africa, where PCa mortality rates were the highest. Countries with higher HDI (r=0.58) and per capita GDP (r=0.62) reported greater incidence rates. According to the most recent 10-yr temporal data available, most countries experienced increases in incidence, with sharp rises in incidence rates in Asia and Northern and Western Europe. A substantial reduction in mortality rates was reported in most countries, except in some Asian countries and Eastern Europe, where mortality increased. Data in regional registries could be underestimated. PCa incidence has increased while PCa mortality has decreased in most countries. The reported incidence was higher in countries with higher socioeconomic development. The incidence of prostate cancer has shown high variations geographically and over time, with smaller

    More than any time in our history, the wood-burning stove continues to be the most popular technology used for cooking and heating worldwide. According to the World Health Organization and recent scientific studies, the inefficient use of solid-fuels in traditional stoves constitutes the major...... systems, improved efficient retrofits and advanced stove innovations. In chapter 3, four popular wood-burning practices found in five countries were singled-out to be examined closely in four case studies: “cooking in Brazil”, “cooking and heating in Peru”, “heating in Portugal” and “recreational heat...

    Actinotignum schaalii (former named Actinobaculum schaalii) can cause urinary tract infections (UTIs) and bacteraemia, mainly in the elderly. A. schaalii is difficult to identify with conventional biochemical tests, and it is often overlooked if the urine is only cultured in ambient air. The aim of this study was to validate data from the nationwide Danish microbiology database (MiBa) with data from the laboratory information system (LIS) at the local department of microbiology in Viborg-Herning, and to evaluate the incidence rate of bacteraemia caused by A. schaalii in Denmark by using data from the MiBa. All departments of microbiology in Denmark report data to the MiBa. All microbiological samples with A. schaalii in Denmark were extracted for a period of 5 years from the MiBa and from the local LISs. All data obtained from our local LIS were also found in the MiBa, except for data on real-time PCR, which were not registered, owing to missing ID codes in the MiBa. From 2010 to 2014, there was a significant increase in the incidence rate of blood cultures with A. schaalii, from 1.8 to 6.8 cases per million, which was probably due to coincident implementation of matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) in routine diagnostics. We found that A. schaalii caused bacteraemia and UTIs mainly in the elderly. In conclusion, the MiBa can be a useful source of nationwide microbiological data in Denmark. Our results suggest that the incidence rate of A. schaalii as a cause of bacteraemia has been underestimated, and that culture of urine in CO2 can improve the detection of A. schaalii.

  2. Health warnings on tobacco products - worldwide, 2007.

    Science.gov (United States)

    2009-05-22

    Many countries require that tobacco product packaging includes health warnings about the risks associated with tobacco use. Health warnings on tobacco product packages are effective in highlighting the perception of health risk, supporting the intention to quit tobacco use, discouraging the intention to begin tobacco use, and increasing cessation rates. Prominent displays of health warnings increase their effectiveness; larger warnings, with pictures, are more likely to be noticed, better communicate health risks, provoke greater emotional response, and further motivate tobacco users to quit. This report assesses the current status of tobacco packaging health warning requirements worldwide. Governments could further discourage tobacco use by requiring prominent health warnings on tobacco packaging.

    Systemic lupus erythematosus (SLE) is a disease of multifactorial etiology. Quantifying the burden of SLE across different countries can clarify the role of genetic, environmental and other causative factors in the natural history of the disease, and to understand its clinical and societal consequences. The aim of this study is to summarize data on SLE incidence and prevalence in the USA, Europe, Asia, and Australia. An extensive review of electronic resources (PubMed and MedLine) and medical journals was conducted to identify published studies on SLE incidence and prevalence over the period of 1950-early 2006. Researchers in the countries of interest provided additional information on the epidemiology of SLE. The incidence and prevalence of SLE varies considerably across the countries. The burden of the disease is considerably elevated among non-white racial groups. There is a trend towards higher incidence and prevalence of SLE in Europe and Australia compared to the U.S.A. In Europe, the highest prevalence was reported in Sweden, Iceland and Spain. There are marked disparities in SLE rates worldwide. This variability may reflect true differences across populations, or result from methodological differences of studies. The true geographic, racial, and temporal differences in SLE incidence and prevalence may yield important clues to the etiology of disease.

    Prior studies suggest that increased urine albumin is associated with a heightened fracture risk in women, but results in men are unclear. We used data from Osteoporotic Fractures in Men (MrOS), a prospective cohort study of community-dwelling men aged ≥65 years, to evaluate the association of increased urine albumin with subsequent fractures and annualized rate of hip bone loss. We calculated albumin/creatinine ratio (ACR) from urine collected at the 2003-2005 visit. Subsequent clinical fractures were ascertained from triannual questionnaires and centrally adjudicated by review of radiographic reports. Total hip BMD was measured by DXA at the 2003-2005 visit and again an average of 3.5 years later. We estimated risk of incident clinical fracture using Cox proportional hazards models, and annualized BMD change using ANCOVA. Of 2982 men with calculable ACR, 9.4% had ACR ≥30 mg/g (albuminuria) and 1.0% had ACR ≥300 mg/g (macroalbuminuria). During a mean of 8.7 years of follow-up, 20.0% of men had an incident clinical fracture. In multivariate-adjusted models, neither higher ACR quintile (p for trend 0.75) nor albuminuria (HR versus no albuminuria, 0.89; 95% CI, 0.65 to 1.20) was associated with increased risk of incident clinical fracture. Increased urine albumin had a borderline significant, multivariate-adjusted, positive association with rate of total hip bone loss when modeled in ACR quintiles (p = 0.06), but not when modeled as albuminuria versus no albuminuria. Macroalbuminuria was associated with a higher rate of annualized hip bone loss compared to no albuminuria (-1.8% more annualized loss than in men with ACR fracture associations. In these community-dwelling older men, we found no association between urine albumin levels and risk of incident clinical fracture, but found a borderline significant, positive association with rate of hip bone loss. © 2016 American Society for Bone and Mineral Research. © 2016 American Society for Bone and

    Our aim was to evaluate the effects of fish oil feeding on sperm classical parameters, level of reactive oxygen spices (ROS), spermatozoa death incidence and in vitro fertilization (IVF) rate in rams. We randomly assigned nine rams, into two experimental groups (isoenergetic and isonitrogenous rations with constant level of vitamin E supplement): control (CTR; n = 5) and fish oil (FO; n = 4, 35 g/day/ram). Diets were fed for 70 days during the physiological breeding season. After a 21-day dietary adaptation period, semen was collected weekly from each ram by an artificial vagina. Sperm classical parameters were determined by the computer-assisted sperm analyzer system (CASA), and it was prepared for IVF process by swim-up technique. These evaluations were performed during the first and last weeks of sampling. Intracellular ROS level and spermatozoa death incidence were detected by flow cytometry on a weekly basis after adaptation. Data were analysed with SPSS 15. The volume, concentration (3.6 and 2.7 × 10(9) /ml) and sperm progressive motility (60 and 48%) were significantly improved in the FO group compared with the CTR (p oil to the ram diet not only improved sperm quality and IVF results, it also could reduce oxygen-free radicals and the incidence of spermatozoa death. © 2014 Blackwell Verlag GmbH.

The case was culture-positive for Staphylococcus epidermidis. Final visual acuity was 20/40 after pars plana vitrectomy surgery.Conclusions: In this series, the incidence of culture-positive endophthalmitis after intravitreal injection of vascular agents in an outpatient setting was very low. We believe that following a standardized injection protocol, adherence to sterile techniques and proper patient follow-up are determining factors for low incidence rates.Keywords: endophthalmitis, intravitreal injections, vascular targeting agents

    Attachment of low-energy electrons to gas phase 9,10-anthraquinone (AQ) was observed with electron transmission (ET) spectroscopy, and interpreted with the support of quantum chemical calculations. The ET spectrum displays three shape resonances at 0.45, 0.7, and 2.2 eV, associated with temporary electron capture into empty π∗ molecular orbitals of AQ, the first two anion states being stable. According to TD-B3LYP calculations, the first π-π ∗ core-excited resonance lies at about 1.8 eV, although no experimental evidence for this anion state was found. The long-lived parent molecular anion [AQ]- was observed by means of Electron Attachment Spectroscopy (EAS) using two different mass spectrometers and also by measuring the total anion current at the collision chamber walls. The molecular anion current shows maxima at zero energy, around 0.6 eV and at 1.8 eV. Association of these maxima with the corresponding resonant anion states is discussed. The experimentally measured electron detachment times from [AQ]- as a function of the incident electron energy and the temperature of the target molecule show a pronounced change of slope around 1.5 eV, regardless of the temperature. This unexpected behavior can be qualitatively reproduced within the framework of a multiexponential approach which describes the electron detachment event in terms of a redistribution of the anion excess energy, regardless of the initial mechanism of temporary anion formation.

    Despite increasing knowledge of the prevalence of borderline personality disorder (BPD) in the general population, and rising awareness of mental disorders both as a categorical and a dimensional construct, research is still lacking on the prevalence of the number of BPD symptoms and their associated consequences, such as comorbidity, disability, and the use of mental health services) in the general population. Data were obtained from the second wave of the Netherlands Mental Health Survey and Incidence Study-2 (N = 5303), a nationally representative face-to-face survey of the general population. BPD symptoms were measured by means of questions from the International Personality Disorder Examination. Comorbidity of common mental disorders was assessed with the Composite International Diagnostic Interview version 3.0. Of the total population studied, 69.9 % reported no BPD symptoms, while 25.2 % had 1-2 symptoms, 3.8 % had 3-4 symptoms, and 1.1 % had ≥ 5 BPD symptoms. The number of BPD symptoms reported was found to be positively associated with not living with a partner, having no paid job, and/or having a comorbid mood, anxiety or substance use disorder. Even after adjustment for sociodemographic characteristics and comorbidity, the number of BPD symptoms turned out to be uniquely associated with disability. It also showed a positive relationship with using services for dealing with mental health problems, although this relationship was strongly affected by the presence of comorbid disorders. Because even a relatively low number of BPD symptoms appears to be associated with psychiatric comorbidity and functional disability, not only full-blown BPD but also subthreshold levels of BPD symptoms need to be identified in clinical practice and research.

    The natural history of cervical degenerative disease with operative management has not been well described. Even with symptomatic and radiographic evidence of multilevel cervical disease, it is unclear whether single- or multilevel anterior cervical discectomy and fusion (ACDF) procedures produce superior long-term outcomes. To describe national trends in revision rates, complications, and readmission for patients undergoing single and multilevel ACDF. Administrative database study. Between 2006 and 2010, 92,867 patients were recorded for ACDF procedures in the Thomson Reuters MarketScan database. Restricting to patients with >24 months follow-up, 28,777 patients fulfilled our inclusion criteria, of which 12,744 (44%) underwent single-level and 16,033 (56%) underwent multilevel ACDFs. Revision rates and postoperative complications. We used the MarketScan database from 2006 to 2010 to select ACDF procedures based on Current Procedural Terminology coding at inpatient visit. Outcome measures were ascertained using either International Classification of Disease version 9 or Current Procedural Terminology coding. Perioperative complications were more common in multilevel procedures (odds ratio [OR], 1.4; 95% confidence interval [CI], 1.2-1.6; p<.0001). Single-level ACDF patients had higher rates of postoperative cervical epidural steroid injections (OR, 0.88; 95% CI, 0.8-1.0; p=.01). Within 30 days after index procedure, the multilevel ACDF cohort was 1.6 times more likely to have undergone revision (OR, 1.6; 95% CI, 1.1-2.4; p=.02). At 2 years follow-up, revision rates were 9.13% in the single-level ACDF cohort and 10.7% for multilevel ACDFs (OR, 1.2; 95% CI, 1.1-1.3; p<.0001). In a multivariate analysis at 2 years follow-up, patients from the multilevel cohort were more likely to have received a surgical revision (OR, 1.1; 95% CI, 1.0-1.2; p=.001), to be readmitted into the hospital for any cause (OR, 1.2; 95% CI, 1.1-1.4; p=.007), and to have suffered complications

    Full Text Available Toxicity is the most frequently reported reason for modifying or discontinuing the first combined antiretroviral therapy regimens, and it can cause significant morbidity, poor quality of life and also can be an important barrier to adherence, ultimately resulting in treatment failure and viral resistance. Elderly patients with HIV/AIDS (≥50 years may have a different profile in terms of treatment modification due to higher incidence of comorbidities and polypharmacy. The aim of this study was to describe the incidence of modifying or discontinuing first combined antiretroviral therapy regimen due to toxicity (TOX-MOD during the first year of treatment at the IPEC – FIOCRUZ HIV/AIDS cohort, Rio de Janeiro, Brazil, stratified by age. Demographic, clinical and treatment characteristics from antiretroviral-naïve patients who first received combined antiretroviral therapy between Jan/1996 and Dec/2010 were collected. Incidence rate and confidence interval of each event were estimated using quasipoisson model. To estimate hazard ratio (HR of TOX-MOD during the first year of combined antiretroviral therapy Cox's proportional hazards regression was applied. Overall, 1558 patients were included; 957 (61.4%, 420 (27.0% and 181 (11.6% were aged <40, 40–49, and ≥50 years, respectively. 239 (15.3% events that led to any modifying or discontinuing within the first year of treatment were observed; 228 (95.4% of these were TOX-MOD, corresponding to an incidence rate of 16.6/100 PY (95% CI: 14.6–18.9. The most frequent TOX-MOD during first combined antiretroviral therapy regimen were hematologic (59; 26.3%, central nervous system (47; 20.9%, rash (42; 19.1% and gastrointestinal (GI (38; 16.7%. In multivariate analysis, incidence ratio of TOX-MOD during the first year of combined antiretroviral therapy progressively increases with age, albeit not reaching statistical significance. This profile was maintained after adjusting the model for sex, combined

We aim to analyze changes in incidence, co-morbidity profile, length of hospital stay (LOHS, costs and in-hospital mortality (IHM of patients undergoing primary total hip arthroplasty (THA over an 8-year study period in Spain. Methods We selected all surgical admissions in individuals aged ≥40 years who had received a primary THA (ICD-9-CM procedure code 81.51 between 2001 and 2008 from the National Hospital Discharge Database. Age- and sex-specific incidence rates, LOHS, costs and IHM were estimated for each year. Co-morbidity was assessed using the Charlson comorbidity index. Multivariate analysis of time trends was conducted using Poisson regression. Logistic regression models were conducted to analyze IHM. Results We identified a total of 161,791 discharges of patients having undergone THA from 2001 to 2008. Overall crude incidence had increased from 99 to 105 THA per 100.000 inhabitants from 2001 to 2008 (p 2 and in 2008, the prevalence of 1-2 or >2 had increased to 20.4% and 1.1% respectively (p Conclusions The current study provides clear and valid data indicating increased incidence of primary THA in Spain from 2001 to 2008 with concomitant reductions in LOHS, slight reduction IHM, but a significant increase in cost per patient.

    Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare but severe cutaneous adverse drug reactions. We assessed incidence, drug exposure and mortality, analysing data obtained from the Lombardy Registry of Severe Cutaneous Reactions (REACT). Data were collected from hospitals in the Italian Lombardy region (9,502,272 people). A trained monitor was sent to the reporting hospital to collect data on drug exposure and clinical features. The algorithm for drug causality for epidermal necrolysis algorithm was applied to assess drug causality. Defined Daily Dose (DDD) was used to express drug consumption. From April 2009 to November 2014, 17 cases of TEN and 59 cases of SJS were collected. The overall incidence rate was 1.40 cases (95%CI, 1.12-1.76) per million people per year. A total of 15 cases died during hospitalization with a mortality rate of 16.9% for SJS and 29.4% for TEN. Overall, 55.4% of cases had a probable or very probable relation with drug exposure. In a total of five patients (6.6%), no causative drug for the reaction was identifiable. Allopurinol contributed to the highest number of cases (23 cases), while the highest incidence based on more than one case reported was observed for cotrimoxazole and lamotrigine, with 5.37 cases (95%CI, 2.09-13.80) and 3.54 (95%CI, 1.21-10.42) per 10 million DDD/year, respectively. We confirmed that SJS and TEN are rare adverse cutaneous reactions. As expected, mortality was influenced by the degree of skin detachment. The profile of drugs associated with the reactions was in agreement with data from other surveillance systems. Copyright © 2015 John Wiley & Sons, Ltd.

    NASA's Controlled Ecological Life Support Systems program attempted to address basic needs of crews, meet stringent payload and power usage restrictions, and minimize space occupancy, by developing living, regenerative ecosystems that would take care of themselves and their inhabitants. An experiment from this program evolved into one of the most widespread NASA spinoffs of all time-a method for manufacturing an algae-based food supplement that provides the nutrients previously only available in breast milk. Martek Biosciences Corporation, in Columbia, Maryland, now manufactures this supplement, and it can be found in over 90 percent of the infant formulas sold in the United States, as well as those sold in over 65 other countries. With such widespread use, the company estimates that over 24 million babies worldwide have consumed its nutritional additives.

  17. Epidemiology of tuberculosis in a low-incidence Italian region with high immigration rates: differences between not Italy-born and Italy-born TB cases

    Science.gov (United States)

    2011-01-01

    Background Emilia Romagna, a northern Italian region, has a population of 4.27 million, of which 9.7% are immigrants. The objective of this study was to investigate the epidemiology of tuberculosis (TB) during the period 1996-2006 in not Italy-born compared to Italy-born cases. Methods Data was obtained from the Regional TB surveillance system, from where personal data, clinical features and risk factors of all notified TB cases were extracted. Results 5377 TB cases were reported. The proportion of immigrants with TB, over the total number of TB cases had progressively increased over the years, from 19.1% to 53.3%. In the not Italy-born population, TB incidence was higher than in Italians (in 2006: 100.7 cases per 100 000 registered not Italy-born subjects and 83.9/100 000 adding 20% of estimated irregular presences to the denominators. TB incidence among Italians was 6.5/100 000 Italians). A progressive rise in the not Italy-born incident cases was observed but associated with a decline in TB incidence. Not Italy-born cases were younger compared to the Italy-born cases, and more frequently classified as "new cases" (OR 2.0 95%CI 1.61-2.49 for age group 20-39); 60.7% had pulmonary TB, 31.6% extra pulmonary and 7.6% disseminated TB.

    Full Text Available Abstract Background Emilia Romagna, a northern Italian region, has a population of 4.27 million, of which 9.7% are immigrants. The objective of this study was to investigate the epidemiology of tuberculosis (TB during the period 1996-2006 in not Italy-born compared to Italy-born cases. Methods Data was obtained from the Regional TB surveillance system, from where personal data, clinical features and risk factors of all notified TB cases were extracted. Results 5377 TB cases were reported. The proportion of immigrants with TB, over the total number of TB cases had progressively increased over the years, from 19.1% to 53.3%. In the not Italy-born population, TB incidence was higher than in Italians (in 2006: 100.7 cases per 100 000 registered not Italy-born subjects and 83.9/100 000 adding 20% of estimated irregular presences to the denominators. TB incidence among Italians was 6.5/100 000 Italians. A progressive rise in the not Italy-born incident cases was observed but associated with a decline in TB incidence. Not Italy-born cases were younger compared to the Italy-born cases, and more frequently classified as "new cases" (OR 2.0 95%CI 1.61-2.49 for age group 20-39; 60.7% had pulmonary TB, 31.6% extra pulmonary and 7.6% disseminated TB. Risk factors for TB in this population group were connected to lower income status (homeless: OR 149.9 95%CI 20.7-1083.3 for age group 40-59. Conclusions In low-incidence regions, prevention and control of TB among sub-groups at risk such as the foreign-born population is a matter of public health concern.

    Worldwide data on terrorist incidents between 1968 and 2004 gathered by the RAND corporation and the Oklahoma City National Memorial Institute for the Prevention of Terrorism (MIPT) were assessed for patterns and trends in morbidity/mortality. The data involve a total of 19,828 events, 7,401 ''adverse'' events (each causing {ge}1 victim), 91,346 cases of casualty (either injury or death) and 25,408 deaths. Analyses revealed a number of interesting patterns and apparently significant trends. Most terror-related adverse events, casualties and deaths involved bombs and guns. Weapon-specific patterns and terror-related risk levels in Israel (ISR) have differed markedly from those of all other regions combined (AOR). ISR had a fatal fraction of casualties about half that of AOR, but has experienced relatively constant lifetime terror-related casualty risks on the order of 0.5%--a level 2 to 3 orders of magnitude more than those experienced in AOR, which have increased {approx}100-fold over the same period. Individual event fatality has increased steadily, the median increasing from 14 to 50%. Lorenz curves obtained indicate substantial dispersion among victim/event rates: about half of all victims were caused by the top 2% (10%) of harm-ranked events in OAR (ISR). Extreme values of victim/event rates were found to be well modeled by classic or generalized Pareto distributions, indicating that these rates have been as predictable as similarly extreme phenomena such as rainfall, sea levels, earthquakes, etc. This observation suggests that these extreme-value patterns may be used to improve strategies to prevent and manage risks associated with terror-related consequences.

    Full Text Available Background: In this study, the patients who were operated in two clinics due to traumatic cranial epidural hematoma (EDH were assessed retrospectively and the factors that increase the costs were tried to be revealed through conducting cost analyses. Methods: The patients who were operated between 2010 and 2016 with the diagnosis of EDH were assessed in terms of age, sex, trauma etiology, Glasgow coma scale (GCS at admission, the period from trauma to hospital arrival, trauma-related injury in other organs, the localization of hematoma, the size of hematoma, length of stay in the intensive care unit (ICU, length of antibiotherapy administration, number of consultations conducted, total cost of in-hospital treatments of the patients and prognosis. Results: Distribution of GCS were, between 13-15 in 18 (36% patients, 9-13 in 23 (46% patients and 3-8 in 9 (18% patients. The reasons for emergency department admissions were fall from high in 29 (58% patients, assault in 11 (22% patients and motor vehicle accident in 10 (20% patients. The average cost per ICU stay was 2838 $ (range=343-20571 $. The average cost per surgical treatment was 314 $. ICU care was approximately 9 times more expensive than surgical treatment costs. The mortality rate of the study cohort was 14% (7 patients. Conclusion: The prolonged period of stay in the ICU, antibiotherapy and repeat head CTs increase the costs for patients who are surgically treated for EDH.

  1. MRI-detection rate and incidence of lumbar bleeding sources in 190 patients with non-aneurysmal SAH.

    Full Text Available Up to 15% of all spontaneous subarachnoid hemorrhages (SAH have a non-aneurysmal SAH (NASAH. The evaluation of SAH patients with negative digital subtraction angiography (DSA is sometimes a diagnostic challenge. Our goal in this study was to reassess the yield of standard MR-imaging of the complete spinal axis to rule out spinal bleeding sources in patients with NASAH.We retrospectively analyzed the spinal MRI findings in 190 patients with spontaneous NASAH, containing perimesencephalic (PM and non-perimesencephalic (NPM SAH, diagnosed by computer tomography (CT and/or lumbar puncture (LP, and negative 2nd DSA.190 NASAH patients were included in the study, divided into PM-SAH (n = 87; 46% and NPM-SAH (n = 103; 54%. Overall, 23 (22% patients had a CT negative SAH, diagnosed by positive LP. MR-imaging of the spinal axis detected two patients with lumbar ependymoma (n = 2; 1,05%. Both patients complained of radicular sciatic pain. The detection rate raised up to 25%, if only patients with radicular sciatic pain received an MRI.Routine radiological investigation of the complete spinal axis in NASAH patients is expensive and can not be recommended for standard procedure. However, patients with clinical signs of low-back/sciatic pain should be worked up for a spinal pathology.

    This study provides a descriptive epidemiological data of thyroid cancer cases diagnosed from 2001 to 2008 among Saudi women, including the frequency and percentage of cases, the crude incidence rate (CIR) and the age-standardised incidence rate (ASIR) stratified by the region and year of diagnosis. This is a retrospective descriptive epidemiological analysis of all Saudi thyroid cancer cases recorded in the Saudi Cancer Registry (SCR) between January 2001 and December 2008. The statistical analyses were applied using descriptive statistics with the Statistical Package for the Social Sciences version 20.0. A total of 2,930 cases were recorded in the SCR between January 2001 and December 2008. The region of Riyadh in Saudi Arabia had the highest overall ASIR at 9.43 per 100,000 women, followed by Tabuk at 7.11 and eastern region at 6.5, while Jazan and Jouf had the lowest average ASIRs at 1.97 and at 2.72, respectively. The region of Qassim recorded the greatest changes of ASIR at 5.5 per 100,000 women from 2001 to 2008. There was a slight increase in the CIRs and ASIRs for thyroid cancer in Saudi Arabia between 2001 and 2008. Riyadh, Tabuk and eastern region were the highest overall ASIR in Saudi Arabia. While, Jazan and Hail had the lowest rates. Finally, the region of Qassim had the highest changes in CIR and ASIR from 2001 to 2008. Further analytical studies are needed to determine the potential risk factors of thyroid cancer disease among Saudi women.

    The present paper examines the occurrence of matters relating to the ending of life, including active euthanasia, which is, technically speaking, illegal worldwide. Interest in this most controversial area is drawn from many varied sources, from legal and medical practitioners to religious and moral ethicists. In some countries, public interest has been mobilized into organizations that attempt to influence legislation relating to euthanasia. Despite the obvious international importance of euthanasia, very little is known about the extent of its practice, whether passive or active, voluntary or involuntary. This examination is based on questionnaires completed by 49 national representatives of the International Association for Suicide Prevention (IASP), dealing with legal and religious aspects of euthanasia and physician-assisted suicide, as well as suicide. A dichotomy between the law and medical practices relating to the end of life was uncovered by the results of the survey. In 12 of the 49 countries active euthanasia is said to occur while a general acceptance of passive euthanasia was reported to be widespread. Clearly, definition is crucial in making the distinction between active and passive euthanasia; otherwise, the entire concept may become distorted, and legal acceptance may become more widespread with the effect of broadening the category of individuals to whom euthanasia becomes an available option. The "slippery slope" argument is briefly considered.

    The worldwide ionospheric data base is scattered over the entire globe. Different data sets are held at different institutions in the U.S., U.S.S.R., Australia, Europe, and Asia. The World Data Centers on the different continents archive and distribute part of the huge data base; the scope and cross section of the individual data holdings depend on the regional and special interest of the center. An attempt is made to pull together all the strings that point toward different ionospheric data holdings. Requesters are provided with the information about what is available and where to get it. An attempt is also made to evaluate the reliability and compatibility of the different data sets based on the consensus in the ionospheric research community. The status and accuracy of the standard ionospheric models are also discussed because they may facilitate first order assessment of ionospheric effects. This is a first step toward an ionospheric data directory within the framework of NSSDC's master directory.

    Described as the commonest single gene cause of learning disability internationally, the incidence of Fragile X syndrome (FXS) has never previously been determined in Ireland. The aim of this work was to determine the observed incidence of FXS in the island of Ireland; the Republic of Ireland (ROI) and Northern Ireland (NI) separately and combined. Ascertainment was achieved for a cross-sectional study by a retrospective, clinical and laboratory database review of positive FXS cases, born in either ROI or NI, between years 2000-2009 inclusive. The observed incidence of FXS per 10,000 live births in the island of Ireland in males was 0.94 (95%CI: 0.75-1.13) or ∼1:10,600 and in females was 0.23 (95%CI: 0.14-0.32) or ∼1:43,000. Comparable testing rates for FXS are present in ROI and NI, with on average 1.48% (1.30% in ROI, 1.96% in NI) of live male births and 0.4% (0.35% in ROI, 0.55% in NI) of live female births undergoing analysis which is comparable to other centres internationally. This study demonstrates the observed incidence of FXS in the island of Ireland is (i) approximately half the estimated worldwide incidence in males and is not explained by low levels of testing, and (ii) approximately one quarter the estimated worldwide incidence in females which may be explained by low levels of testing. © 2017 Wiley Periodicals, Inc. © 2017 Wiley Periodicals, Inc.

  7. Worldwide Status of EUV Astronomy

    The bulk of radiation from million-degree plasmas is emitted at EUV wavelengths, which include critical spectral features containing diagnostic information often not available at other wavelengths (e.g., He II Ly series 228-304 Å). Thus, EUV astrophysics (Barstow & Holberg 2003) presents opportunities for intriguing results obtainable with sensitive high-resolution spectroscopy and particularly applicable to hot plasmas in stellar coronae, white dwarfs and the interstellar medium. The US-built J-PEX spectrometer has flown twice on sounding rockets, observing and publishing results on two white dwarf targets (Cruddace et al. 2002, Barstow et al. 2005, Kowalski et al. 2011). Using multilayer-grating technology, J-PEX delivers both high effective area and the world's highest resolution in EUV, greater than Chandra at adjacent energies, but in a waveband Chandra cannot reach. However, the US program has been stalled by inability to obtain further NASA sounding rocket flights. A high level of technology readiness, plus important questions answerable solely with that technology, does not seem sufficient to win support. Nor is the substantial amount of resources invested into technology development over two decades, supported by NASA, DoD, and European partners. Proposals to turn the instrument or its technology into small satellite-based surveys have been made (results to be described) in the US and Europe, but the overall situation is precarious. The entire EUV astrophysics field is losing out on an opportunity, and is at risk of fading away, with forced discard of established assets. Only mobilization of the international EUV community -- unifying European, US, and perhaps others -- can reverse this situation. Our poster summarizes science quests within reach of proven technology, gives a current snapshot of that technology, and provides a summary of worldwide efforts to obtain necessary space access in NASA, ESA, and elsewhere.

    (i) To estimate the rate ratio (RR) of use of alcohol alone, cocaine alone, and both substances simultaneously on acute injury or an aggressive incident, (ii) to compare the RRs for simultaneous use within 3 or 6h of the event; and (iii) to compare the RRs of two measures of exposure, "hours of feeling effects" vs estimates based on self-reported quantity and frequency of use. The study employed a case-crossover design with the frequency approach. Clients (N=616) in substance abuse treatment for alcohol or cocaine issues from 2009 to 2012 completed a self-administered questionnaire on their substance use within 3 and 6h before a recent injury or physically aggressive incident. Clients also reported detailed quantity and frequency information in relation to their typical substance use, as well as information on "feeling effects". The RR of acute harms due to substance use was estimated using the Mantel-Haenszel estimator. In the 6-h window before the event, use of cocaine alone, alcohol alone and simultaneous alcohol and cocaine use were each significantly (Paggressive incident. Simultaneous use was not significantly greater than use of either drug alone. Estimates of RR based on simultaneous use for a 3-h window before the event were consistently larger than those based on a 6-h window, and comparisons were significant (Paggressive incident but not an injury. With reference to the two measures of exposure, three of eight comparisons of RRs were significantly larger for feeling the effects of the substance in comparison to quantity and frequency of substance use. These findings are consistent with increased likelihood of harms related to the acute effects of alcohol alone, cocaine alone or simultaneous use. The results are suggestive that the acute effects of these drugs may be better measured within a 3-h time window than a 6-h window. Finally, we found that "hours of feeling effects" yielded higher estimates of RR than the quantity-frequency approach; however both

  9. Epidemiology of hip fracture: Worldwide geographic variation

    Full Text Available Osteoporosis is a major health problem, especially in elderly populations, and is associated with fragility fractures at the hip, spine, and wrist. Hip fracture contributes to both morbidity and mortality in the elderly. The demographics of world populations are set to change, with more elderly living in developing countries, and it has been estimated that by 2050 half of hip fractures will occur in Asia. This review conducted using the PubMed database describes the incidence of hip fracture in different regions of the world and discusses the possible causes of this wide geographic variation. The analysis of data from different studies show a wide geographic variation across the world, with higher hip fracture incidence reported from industrialized countries as compared to developing countries. The highest hip fracture rates are seen in North Europe and the US and lowest in Latin America and Africa. Asian countries such as Kuwait, Iran, China, and Hong Kong show intermediate hip fracture rates. There is also a north-south gradient seen in European studies, and more fractures are seen in the north of the US than in the south. The factors responsible of this variation are population demographics (with more elderly living in countries with higher incidence rates and the influence of ethnicity, latitude, and environmental factors. The understanding of this changing geographic variation will help policy makers to develop strategies to reduce the burden of hip fractures in developing countries such as India, which will face the brunt of this problem over the coming decades.

    The terrorist attacks that occurred on September 11, 2001 (hereafter referred to as 9/11) in the United States had a profound impact on the physical and mental health of Americans, but the effects beyond the United States are largely unknown. To understand the wider aftermath, we examined the consequences of the 9/11 attacks on mental disorders in the Kingdom of Denmark. Utilizing population data from the Danish Psychiatric Central Research Register from 1995 to 2012, we used a time-series intervention approach to estimate the change in the incidence rate of mental disorders after the 9/11 attacks. Based on analyses of 1,448,250 contacts with psychiatric services, we found that the attacks were followed by an immediate 16% increase in the incidence rate of trauma- and stressor-related disorders. This surge dissipated approximately a year after 9/11. In contrast, no similar increases were found for other disorders. This is consistent with the prominent role of external stressors in the etiology of trauma- and stressor-related disorders. The results indicate that the effects of 9/11 on mental disorders extended across the Atlantic Ocean to Denmark. Thus, the impact of terrorist attacks on mental health is likely not limited to inhabitants of the country under attack; it also extends to people far away and without immediate relation to it. © The Author 2016.

    The purpose of this study was to determine the cross-sectional association between some sociodemographic factors and antiretroviral therapy (ART), as well as the incidence and predictors of type 2 diabetes mellitus among Central Africans with human immunodeficiency virus (HIV) disease. This study had a cross-sectional design and was a prospective analysis of 102 patients with HIV disease (49 on ART versus 53 not on ART) in Kinshasa, Democratic Republic of Congo, between 2004 and 2008. A Cox regression model was used to assess for any relationship between type 2 diabetes and exposure to combination ART without protease inhibitors, after adjusting for known risk factors for type 2 diabetes, nadir CD4 and CD8 levels, viral load, marital status, and religion. Unexpectedly elevated rates of smoking, excess alcohol intake, and ART-related total, abdominal, and peripheral obesity were observed in our study group of HIV patients. At the end of follow-up, five patients were diagnosed with type 2 diabetes (incidence rate 4.9%, 9.8 per 1000 person-years). Univariate risk factors for type 2 diabetes were male gender (relative risk [RR] 1.1, 95% confidence interval [CI] 1.01-1.4; P = 0.019), traditional religion versus new charismatic religion (RR 1.1, 95% CI 1.01-1.3; P = 0.046), exposure to ART (RR 1.1, 95% CI 1.002-1.3; P = 0.034), and single status (RR 6.2, 95% CI 1.5-15; P = 0.047). In multivariate analysis, strong significant independent predictors of type 2 diabetes were belonging to a traditional religion (HR 2.1, 95% CI 1.1-4.2; P = 0.036) and a relative increase in nadir CD4 cell count (beta coefficient 0.003; P religion status appear to be the strongest independent predictors of type 2 diabetes.

    Commercial fishing has high rates of work-related injury and death and needs preventive strategies. Work-related fatal and nonfatal injury rates for New Jersey (NJ) commercial fishermen who suffered unintentional traumatic injuries from 2001 to 2007 are calculated using data from the United States Coast Guard (USCG) Marine Safety and Pollution Database and estimated denominator data. Fatalities were compared to those ascertained by the NJ Fatality Assessment Control and Evaluation (FACE) surveillance system. For the study years, 225 nonfatal injuries and 31 fatal injuries were reported. Among nonfatal injuries, the causes by frequency were fall onto surface, crushed between objects, struck by moving object, line handling/caught in lines, collision with fixed objects, fall into water, and other noncontact injuries. The distribution of fatal injuries differed, with the most frequent cause as crushed between objects. Falls into water and several noncontact injuries accounted for most of the other fatalities. The large majority (96%) of nonfatal injuries were contact injuries, whereas only 68% of fatalities were classified as contact. The overall incidence rate of nonfatal injuries was 1188 per 100,000 full-time equivalents (FTEs) per year. The rate varied considerably by year, from a low of 286 per 100,000 FTEs in 2001 and 2007 to 3806 per 100,000 FTEs in 2003. The overall occupational fatality rate over the period 2001-2007 was 164 per 100,000 FTEs per year. These results can aid in targeting the commercial fishing industry for injury prevention strategies and interventions, especially for falls, crushing injuries, and drownings.

  14. Subcutaneous bortezomib in multiple myeloma patients induces similar therapeutic response rates as intravenous application but it does not reduce the incidence of peripheral neuropathy.

    Jiri Minarik

    Full Text Available Subcutaneous (SC application of bortezomib has been recently introduced as a new application route in multiple myeloma (MM patients. We performed an analysis to compare the outcomes of bortezomib-based therapy in multiple myeloma (MM patients treated using either intravenous (IV or subcutaneous (SC route of administration.During January 2012 through December 2013, we performed a retrospective analysis of 446 patients with MM treated with bortezomib-based regimens (either once weekly - 63% or twice weekly - 27% in both, the first line setting, and in relapse, with separate analysis of patients undergoing autologous stem cell transplantation. We assessed the response rates and toxicity profiles in both, IV and SC route of bortezomib administration.The response rates in both IV and SC arm were similar with overall response rate 71.7% vs 70.7%, complete remissions in 13.9% vs 8.6%, very good partial remissions in 30.8% vs 34.5% and partial remissions in 27% vs 27.6%. The most frequent grade ≥ 3 toxicities were anemia, thrombocytopenia and neutropenia, with no significant differences between IV and SC group. There were no significant differences in the rate of peripheral neuropathy (PN. PN of any grade was present in 48% in the IV arm and in 41% in the SC arm. PN grade ≥ 2 was present in 20% vs 18% and PN grade ≥ 3 was present in 6% vs 4%.We conclude that subcutaneous application of bortezomib has similar therapeutic outcomes and toxicity profile as intravenous route of application. In our cohort there was no difference in the incidence of PN, suggesting that PN is dose dependent and might be reduced by lower intensity schemes rather than by the route of administration.

    Background This study presents descriptive epidemiological data related to breast cancer cases diagnosed from 2001 to 2008 among Saudi women, including the frequency and percentage of cases, the crude incidence rate (CIR), and the age-standardized incidence rate (ASIR), adjusted by the region and year of diagnosis. Methods This is a retrospective descriptive epidemiological study of all Saudi female breast cancer cases from 2001 to 2008. The statistical analyses were conducted using descriptive statistics, a linear regression model, and analysis of variance with the Statistical Package for the Social Sciences version 20.0. Results A total of 6,922 female breast cancer cases were recorded in the Saudi Cancer Registry from 2001 to 2008. The highest overall percentages (38.6% and 31.2%) of female breast cancer cases were documented in women who were 30–44 and 45–59 years of age, respectively. The eastern region of Saudi Arabia had the highest overall ASIR, at 26.6 per 100,000 women, followed by Riyadh at 20.5 and Makkah at 19.4. Jazan, Baha, and Asir had the lowest average ASIRs, at 4.8, 6.1, and 7.3 per 100,000 women, respectively. The region of Jouf (24.2%; CIR 11.2, ASIR 17.2) had the highest changes in CIR and ASIR from 2001 to 2008. While Qassim, Jazan, and Tabuk recorded down-trending rates with negative values. Conclusion There was a significant increase in the CIRs and ASIRs for female breast cancer between 2001 and 2008. The majority of breast cancer cases occurred among younger women. The region of Jouf had the greatest significant differences of CIR and ASIR during 2001 to 2008. Jazan, Baha, and Najran had the lowest average CIRs and ASIRs of female breast cancer, whereas the linear trend upward is a concern in certain regions, such as the eastern region, Makkah, and Riyadh. However, further analytical epidemiological research is needed to identify the potential risk factors involved in the increase in the prevalence of breast cancer among Saudi women

Methods: This is a retrospective descriptive epidemiological study of all Saudi female breast cancer cases from 2001 to 2008. The statistical analyses were conducted using descriptive statistics, a linear regression model, and analysis of variance with the Statistical Package for the Social Sciences version 20 (IBM Corporation, Armonk, NY, USA. Results: A total of 6,922 female breast cancer cases were recorded in the Saudi Cancer Registry from 2001 to 2008. The highest overall percentages (38.6% and 31.2% of female breast cancer cases were documented in women who were 30–44 and 45–59 years of age, respectively. The eastern region of Saudi Arabia had the highest overall ASIR, at 26.6 per 100,000 women, followed by Riyadh at 20.5 and Makkah at 19.4. Jazan, Baha, and Asir had the lowest average ASIRs, at 4.8, 6.1, and 7.3 per 100,000 women, respectively. The region of Jouf (24.2%; CIR 11.2, ASIR 17.2 had the highest changes in CIR and ASIR from 2001 to 2008. While Qassim, Jazan and Tabuk recorded down-trending rates with negative values. Conclusion: There was a significant increase in the CIRs and ASIRs for female breast cancer between 2001 and 2008. The majority of breast cancer cases occurred among younger women. The region of Jouf had the greatest significant

    In patients with chronic kidney disease (CKD) hyperuricemia is common. Evidence that hyperuricemia might also play a causal role in vascular disease, hypertension and progression of CKD is accumulating. Therefore, we studied the association between baseline uric acid (UA) levels and the rate of decline in renal function and time until start of dialysis in pre-dialysis patients. Data from the PREPARE-2 study were used. The PREPARE-2 study is an observational prospective cohort study including incident pre-dialysis patients with CKD stages IV-V in the years between 2004 and 2011. Patients were followed for a median of 14.9 months until start of dialysis, kidney transplantation, death, or censoring. Main outcomes were the change in the rate of decline in renal function (measured as estimated glomerular filtration rate (eGFR)) estimated using linear mixed models, and time until start of dialysis estimated using Cox proportional hazards models. In this analysis 131 patients were included with a baseline UA level (mean (standard deviation (SD)) of 8.0 (1.79) mg/dl) and a mean decline in renal function of -1.61 (95% confidence interval (CI), -2.01; -1.22) ml/min/1.73 m2/year. The change in decline in GFR associated with a unit increase in UA at baseline was -0.14 (95% CI -0.61;0.33, p=0.55) ml/min/1.73 m2/year. Adjusted for demography, comorbidities, diet, body mass index (BMI), blood pressure, lipids, proteinuria, diuretic and/or allopurinol usage the change in decline in eGFR did not change. The hazard ratio (HR) for starting dialysis for each mg/dl increase in UA at baseline was 1.08 (95% CI, 0.94;1.24, p=0.27). After adjustment for the same confounders the HR became significant at 1.26 (95% CI, 1.06;1.49, p=0.01), indicating an earlier start of dialysis with higher levels of UA. Although high UA levels are not associated with an accelerated decline in renal function, a high serum UA level in incident pre-dialysis patient is a risk factor for an earlier start of

    The Guillain-Barré syndrome (GBS) occurs after infections and as an adverse reaction to vaccines. No detailed information on incidence rates (IRs) in Germany is available. This retrospective cohort study estimated age- and sex-specific IRs of GBS in Germany in the years 2007-2009 based on electronic healthcare data from the German Pharmacoepidemiological Research Database (GePaRD). Two case definitions were applied. GBS cases had a main discharge diagnosis of GBS. GBS_PROCEDURE cases in addition had codes for relevant diagnostic procedures. Crude and standardized IRs (SIRs) with 95% confidence intervals were stratified by year, age group, sex, region and season. IR ratios (IRRs) for each stratification factor were calculated by multivariable Poisson regression. Among 13,297,678 persons, 889 (693) incident GBS (GBS_PROCEDURE) cases were identified. Overall SIRs per 100,000 person years were 2.4 (2.2-2.5) for GBS and 1.8 (1.7-2.0) for GBS_PROCEDURE. (S)IRs increased with age, peaking in the age group 70-79 years (IR GBS: 5.5 (4.7-6.5)) and were higher in males than in females (e.g., IR GBS: IRR = 1.5 (1.3-1.7)) and in February-April, as compared to the rest of the year. No regional pattern was observed. (S)IRs of GBS in Germany differed by age, sex and season and were comparable to those found in other studies. RESULTS might be used as a comparator in vaccine safety monitoring. © 2014 S. Karger AG, Basel.

    Background Although pre-existing renal insufficiency (RI) is the most important risk factor for contrast-induced nephropathy (CIN), the background distribution of baseline renal function has not been investigated thoroughly in patients scheduled for contrast-enhanced CT. Purpose To investigate the incidence and severity of baseline RI evaluated by estimated glomerular filtration rates (eGFR) in patients who underwent contrast-enhanced CT at an academic center. Material and Methods A total of 6586 patients (3630 men and 2956 women; mean age 57.0 +- 11.9 years) who underwent contrast-enhanced CT between January and December 2008 were retrospectively studied. Of these, 829 had cardiovascular diseases (CVD), 5116 had oncologic diseases, 178 had diabetes mellitus (DM), and 1572 had chronic liver disease (CLD). The eGFR (mL/min/1.73 m2) was calculated from their serum creatinine level. Mild, moderate-a, moderate-b, and severe RI were recorded at 60 < =eGFR < 90, 45 < =eGFR < 60, 30 < =eGFR < 45 and eGFR < 30, respectively. Results Of the 6586 patients, 1.6%, 3.7%, 13.7%, and 54.2% were judged to present with severe, moderate-b, moderate-a, and mild RI, respectively. While moderate-b-to-severe RI was recorded in 133 (3.2%) of 4161 patients aged 70 years or less, it was observed in 218 (9.0%) of the 2425 patients who were 71 years or older. Among the 829 CVD patients, 9.9% manifested moderate-b-to-severe- and 73.0% mild-to-moderate-a RI. The corresponding rates were 4.4% and 68.9% for oncologic disease, 16.9% and 61.2% for DM, and 4.8% and 71.5% for CLD patients. By univariate analysis, there was a significant association between moderate-b-to-severe RI and the advanced age, CVD, DM, and non-oncologic disease. Multivariate analysis showed that the advanced age, DM, and non-oncologic disease were statistically associated with moderate-b-to-severe RI. Conclusion The incidence of RI of eGFR < 45mL/min/1.73 m2 at baseline was high in patients with advanced age, CVD and DM and

    Despite wide variations in hip rates fractures worldwide, reasons for such differences are not clear. Furthermore, secular trends in the age-specific hip fracture rates are changing the world map of this devastating disease, with the highest rise projected to occur in developing countries. The aim of our investigation is to systematically characterize secular trends in hip fractures worldwide, examine new data for various ethnic groups in the United States, evidence for divergent temporal patterns, and investigate potential contributing factors for the observed change in their epidemiology. All studies retrieved through a complex Medline Ovid search between 1966 and 2013 were examined. For each selected study, we calculated the percent annual change in age-standardized hip fracture rates de-novo. Although occurring at different time points, trend breaks in hip fracture incidence occurred in most Western countries and Oceania. After a steep rise in age-adjusted rates in these regions, a decrease became evident sometimes between the mid-seventies and nineties, depending on the country. Conversely, the data is scarce in Asia and South America, with evidence for a continuous rise in hip fracture rates, with the exception of Hong-Kong and Taiwan that seem to follow Western trends. The etiologies of these secular patterns in both the developed and the developing countries have not been fully elucidated, but the impact of urbanization is at least one plausible explanation. Data presented here show close parallels between rising rates of urbanization and hip fractures across disparate geographic locations and cultures. Once the proportion of the urban population stabilized, hip fracture rates also stabilize or begin to decrease perhaps due to the influence of other factors such as birth cohort effects, changes in bone mineral density and BMI, osteoporosis medication use and/or lifestyle interventions such as smoking cessation, improvement in nutritional status and fall

    BACKGROUND: The world-wide interest in bipolar disorder is illustrated by an exponential increase in publications on the disorder registered in Pubmed since 1990. This inspired an investigation of the epidemiology of bipolar disorder. METHODS: This was a register-based cohort study. All first......-ever diagnoses of bipolar disorder (International Classification of Diseases-10: F31) were identified in the nationwide Danish Psychiatric Central Research Register between 1995 and 2012. Causes of death were obtained from The Danish Register of Causes of Death. Age- and gender standardized incidence rates......, standardized mortality ratio (SMR) and Kaplan-Meier survival estimates were calculated. RESULTS: We identified 15,334 incident cases of bipolar disorder. The incidence rate increased from 18.5/100,000 person-years (PY) in 1995 to 28.4/100,000 PY in 2012.

    To determine incidence rates (IRs) and potential risk factors for owner-reported adverse events (AEs) following vaccination of dogs that did or did not receive a Leptospira vaccine. Observational, retrospective cohort study. 130,557 dogs. Electronic records of mobile veterinary clinics from June 2012 to March 2013 were searched to identify dogs that received ≥ 1 vaccine in a given visit. Signalment data, vaccinations received, medications administered, and owner-reported clinical signs consistent with AEs that developed ≤ 5 days after vaccination were recorded. Associations between potential risk factors and owner-reported AEs were evaluated by logistic regression analysis. The IR/10,000 dogs for owner-reported postvaccination AEs was 26.3 (95% CI, 23.6 to 29.2), whereas that for dogs that received a Leptospira vaccine alone or with other vaccines was 53.0 (95% CI, 42.8 to 64.9). Significant factors for increasing or decreasing risk of AEs were as follows: receiving a Leptospira vaccine (adjusted OR, 2.13), age at vaccination 1 to Leptospira component. The overall IR for owner-reported postvaccination AEs was low. Results suggested vaccination against Leptospira (an organism that can cause fatal disease) is safe in the majority of cases, slightly increasing the risk of owner-reported AEs but not associated with a significant increase in hypersensitivity reactions, compared with other vaccinations administered.

    Bladder cancer has become a common cancer globally, with an estimated 430 000 new cases diagnosed in 2012. We examine the most recent global bladder cancer incidence and mortality patterns and trends, the current understanding of the aetiology of the disease, and specific issues that may influence the registration and reporting of bladder cancer. Global bladder cancer incidence and mortality statistics are based on data from the International Agency for Research on Cancer and the World Health Organisation (Cancer Incidence in Five Continents, GLOBOCAN, and the World Health Organisation Mortality). Bladder cancer ranks as the ninth most frequently-diagnosed cancer worldwide, with the highest incidence rates observed in men in Southern and Western Europe, North America, as well in certain countries in Northern Africa or Western Asia. Incidence rates are consistently lower in women than men, although sex differences varied greatly between countries. Diverging incidence trends were also observed by sex in many countries, with stabilising or declining rates in men but some increasing trends seen for women. Bladder cancer ranks 13th in terms of deaths ranks, with mortality rates decreasing particularly in the most developed countries; the exceptions are countries undergoing rapid economic transition, including in Central and South America, some central, southern, and eastern European countries, and the Baltic countries. The observed patterns and trends of bladder cancer incidence worldwide appear to reflect the prevalence of tobacco smoking, although infection with Schistosoma haematobium and other risk factors are major causes in selected populations. Differences in coding and registration practices need to be considered when comparing bladder cancer statistics geographically or over time. The main risk factor for bladder cancer is tobacco smoking. The observed patterns and trends of bladder cancer incidence worldwide appear to reflect the prevalence of tobacco smoking

    Transmission of tuberculosis (TB) in prisons has been reported worldwide to be much higher than that reported for the corresponding general population. A systematic review has been performed to assess the risk of incident latent tuberculosis infection (LTBI) and TB disease in prisons, as compared to the incidence in the corresponding local general population, and to estimate the fraction of TB in the general population attributable (PAF%) to transmission within prisons. Primary peer-reviewed studies have been searched to assess the incidence of LTBI and/or TB within prisons published until June 2010; both inmates and prison staff were considered. Studies, which were independently screened by two reviewers, were eligible for inclusion if they reported the incidence of LTBI and TB disease in prisons. Available data were collected from 23 studies out of 582 potentially relevant unique citations. Five studies from the US and one from Brazil were available to assess the incidence of LTBI in prisons, while 19 studies were available to assess the incidence of TB. The median estimated annual incidence rate ratio (IRR) for LTBI and TB were 26.4 (interquartile range [IQR]: 13.0-61.8) and 23.0 (IQR: 11.7-36.1), respectively. The median estimated fraction (PAF%) of tuberculosis in the general population attributable to the exposure in prisons for TB was 8.5% (IQR: 1.9%-17.9%) and 6.3% (IQR: 2.7%-17.2%) in high- and middle/low-income countries, respectively. The very high IRR and the substantial population attributable fraction show that much better TB control in prisons could potentially protect prisoners and staff from within-prison spread of TB and would significantly reduce the national burden of TB. Future studies should measure the impact of the conditions in prisons on TB transmission and assess the population attributable risk of prison-to-community spread.

    Antineutrinos produced at nuclear reactors constitute a severe source of background for the detection of geoneutrinos, which bring to the Earth's surface information about natural radioactivity in the whole planet. In this framework, we provide a reference worldwide model for antineutrinos from reactors, in view of reactors operational records yearly published by the International Atomic Energy Agency. We evaluate the expected signal from commercial reactors for ongoing (KamLAND and Borexino), planned (SNO +), and proposed (Juno, RENO-50, LENA, and Hanohano) experimental sites. Uncertainties related to reactor antineutrino production, propagation, and detection processes are estimated using a Monte Carlo-based approach, which provides an overall site-dependent uncertainty on the signal in the geoneutrino energy window on the order of 3%. We also implement the off-equilibrium correction to the reference reactor spectra associated with the long-lived isotopes, and we estimate a 2.4% increase of the unoscillated event rate in the geoneutrino energy window due to the storage of spent nuclear fuels in the cooling pools. We predict that the research reactors contribute to less than 0.2% to the commercial reactor signal in the investigated 14 sites. We perform a multitemporal analysis of the expected reactor signal over a time lapse of ten years using reactor operational records collected in a comprehensive database published at www.fe.infn.it/antineutrino.

    National epidemiological studies of forearm fractures are scarce. We examined in- and outpatient rates in Denmark, including anatomical location, surgery, hospitalization ratio, recurrent fractures, and ratio of forearm to hip fractures. This may be useful for triangulation in countries with less detailed information. Rates were higher than previously estimated. Despite a significant contribution to the overall burden of osteoporotic, nonvertebral fractures, relatively little information is available about age- and gender-specific incidence rates for many countries including Denmark. We used national individual patient data on inpatient and outpatient treatment to calculate rates of forearm fractures, taking readmissions into account, with subtables for distal and proximal fractures. We also calculated ratios of forearm to hip fractures that may be useful when imputing forearm fracture rates from other administrative sources. In addition, we report the rates of hospital admission and the rates of surgical treatment, allowing readers to extrapolate from the number of admissions or surgical procedures to incidence rates, should their data sources be less comprehensive. Forearm fracture rates were 278 per 100,000 patient years in men aged 50+ and 1,110 per 100,000 in women aged 50+. The female to male incidence rate ratio was 4.0 for the age group 50+ but close to unity in persons aged 40 or under. Two thirds of patients were treated on an outpatient basis with little difference across age and gender strata. Four out of five fractures were treated conservatively. The rate of forearm fractures in Denmark was somewhat higher in both genders than recently imputed from hip fracture rates and were close to the rates previously reported in studies from Norway and Sweden. The rates of forearm fracture in Denmark are higher than previously estimated and very similar to the high risk reported from studies in Norway and Sweden.

    The optimal treatment of humeral shaft fractures continues to be debated. In the current investigation, we sought to determine the clinical and radiographic outcomes following the plate fixation of humeral shaft fractures utilizing the triceps-sparing posterior approach. A retrospective review identified a consecutive series of 66 humeral shaft fractures (OTA 12-A, 12-B, or 12-C) treated with dual plate fixation via a posterior, triceps-sparing approach between 2005 and 2014 by a single surgeon. Demographics, operative reports, clinical follow-up, and preoperative radiographs were reviewed. Postoperative radiographs were assessed for angular deformity and time to union. Range of motion and strength testing were also reviewed. A total of 66 humeral shaft fractures were reviewed with a mean clinical follow-up of 8.0 months. The mean time to union was 15.6 ± 11.1 weeks, and there was one case of delayed union. Seventeen of 66 (25.8 %) patients presented with a primary radial nerve palsy following injury, and 14 of the 17 (82 %) of the preoperative radial nerve palsies fully resolved at an average of 31 weeks following injury. Two additional patients developed radial nerve palsies postoperatively (3.0 %). This is a large consecutive series of humeral shaft fractures treated with plating through a posterior approach by a single surgeon. The triceps-sparing posterior approach to the humerus results in high union rates and a low incidence of secondary radial nerve palsy. Level IV, Case Series.

    To evaluate and analyze ovary cancer incidence and mortality in China in 2011 using ovary cancer data from population-based cancer registration in China, and to provide scientific information for its control and prevention. Invasive cases of ovary cancer were extracted and analyzed from the overall Chinese cancer database in 2011, which were based on data from 177 population-based cancer registries distributing in 28 provinces. The crude, standardized, and truncated incidences and mortalities et al. were calculated and new and deaths cases from ovary cancer throughout China and in different regions in 2011 were estimated using Chinese practical population. The estimates of new ovary cancer cases and deaths were 45,223 and 18,430, respectively, in China in 2011. The crude incidence rate, age-standardized rate by Chinese standard population (ASR-C) and age-standardized rate by world standard population (ASR-W) incidence were 6.89/100,000, 5.35/100,000 and 5.08/100,000, respectively; the crude, ASR-C and ASR-W mortalities were 2.81/100,000, 2.01/100,000 and 1.99/100,000, respectively. The incidence and mortality in urban areas were higher than those in rural areas. The age-specific incidence and mortality increased rapidly from age 35-39 and peaked at age 60-64 or 75-79 years. After age 45 or 55, the age-specific incidence and death rates in urban were much higher than those in rural areas. Compared with GLOBOCAN 2012 data, the ovary cancer incidence in China in 2011 was at middle level, but its mortality was at low level worldwide.

    Purpose Lung cancer is a leading cause of cancer death worldwide. While smoking remains the predominant cause of lung cancer, lung cancer in never-smokers is an increasingly prominent public health issue. Data on this topic, particularly lung cancer incidence rates in never-smokers, however, are limited. Methods We review the existing literature on lung cancer incidence and mortality rates among never-smokers and present new data regarding rates in never-smokers from large, population-based cohorts: 1) Nurses’ Health Study, 2) Health Professionals Follow-up Study, 3) California Teachers Study, 4) Multiethnic Cohort Study, 5) Swedish Lung Cancer Register in the Uppsala/Örebro region, and the 6) First National Health and Nutrition Examination Survey Epidemiologic Follow-up Study. Results Truncated age-adjusted incidence rates of lung cancer among never-smokers aged 40 to 79 years in these six cohorts ranged from 14.4 to 20.8 per 100,000 person-years in women and 4.8 to 13.7 per 100,000 person-years in men, supporting earlier observations that women are more likely than men to have non-smoking-associated lung cancer. The distinct biology of lung cancer in never-smokers is apparent in differential responses to epidermal growth factor receptor inhibitors and an increased prevalence of adenocarcinoma histology in never-smokers. Conclusion Lung cancer in never-smokers is an important public health issue needing further exploration of its incidence patterns, etiology, and biology. PMID:17290054

    Objective Rising global temperatures might contribute to the current worldwide diabetes epidemic, as higher ambient temperature can negatively impact glucose metabolism via a reduction in brown adipose tissue activity. Therefore, we examined the association between outdoor temperature and diabetes incidence in the USA as well as the prevalence of glucose intolerance worldwide. Research design and methods Using meta-regression, we determined the association between mean annual temperature and diabetes incidence during 1996–2009 for each US state separately. Subsequently, results were pooled in a meta-analysis. On a global scale, we performed a meta-regression analysis to assess the association between mean annual temperature and the prevalence of glucose intolerance. Results We demonstrated that, on average, per 1°C increase in temperature, age-adjusted diabetes incidence increased with 0.314 (95% CI 0.194 to 0.434) per 1000. Similarly, the worldwide prevalence of glucose intolerance increased by 0.170% (95% CI 0.107% to 0.234%) per 1°C rise in temperature. These associations persisted after adjustment for obesity. Conclusions Our findings indicate that the diabetes incidence rate in the USA and prevalence of glucose intolerance worldwide increase with higher outdoor temperature. PMID:28405341

  20. Worldwide trend of atmospheric mercury since 1995

    Full Text Available Concern about the adverse effects of mercury on human health and ecosystems has led to tightening emission controls since the mid 1980s. But the resulting mercury emissions reductions in many parts of the world are believed to be offset or even surpassed by the increasing emissions in rapidly industrializing countries. Consequently, concentrations of atmospheric mercury are expected to remain roughly constant. Here we show that the worldwide atmospheric mercury concentrations have decreased by about 20 to 38 % since 1996 as indicated by long-term monitoring at stations in the Southern and Northern Hemispheres combined with intermittent measurements of latitudinal distribution over the Atlantic Ocean. The total reduction of the atmospheric mercury burden of this magnitude within 14 years is unusually large among most atmospheric trace gases and is at odds with the current mercury emission inventories with nearly constant anthropogenic emissions over this period. This suggests a major shift in the biogeochemical cycle of mercury including oceans and soil reservoirs. Decreasing reemissions from the legacy of historical mercury emissions are the most likely explanation for this decline since the hypothesis of an accelerated oxidation rate of elemental mercury in the atmosphere is not supported by the observed trends of other trace gases. Acidification of oceans, climate change, excess nutrient input and pollution may also contribute by their impact on the biogeochemistry of ocean and soils. Consequently, models of the atmospheric mercury cycle have to include soil and ocean mercury pools and their dynamics to be able to make projections of future trends.

  1. Incidence Angle Effect of Energetic Carbon Ions on Deposition Rate, Topography, and Structure of Ultrathin Amorphous Carbon Films Deposited by Filtered Cathodic Vacuum Arc

    The effect of the incidence angle of energetic carbon ions on the thickness, topography, and structure of ultrathin amorphous carbon (a-C) films synthesized by filtered cathodic vacuum arc (FCVA) was examined in the context of numerical and experimental results. The thickness of a-C films deposited at different incidence angles was investigated in the light of Monte Carlo simulations, and the calculated depth profiles were compared with those obtained from high-resolution transmission electron microscopy (TEM). The topography and structure of the a-C films were studied by atomic force microscopy (AFM) and X-ray photoelectron spectroscopy (XPS), respectively. The film thickness decreased with the increase of the incidence angle, while the surface roughness increased and the content of tetrahedral carbon hybridization (sp 3) decreased significantly with the increase of the incidence angle above 45° , measured from the surface normal. TEM, AFM, and XPS results indicate that the smoothest and thinnest a-C films with the highest content of sp 3 carbon bonding were produced for an incidence angle of 45°. The findings of this study have direct implications in ultrahigh-density magnetic recording, where ultrathin and smooth a-C films with high sp 3 contents are of critical importance. © 2012 IEEE.

    -infection, as well as in the rates of detection of new cases of active and latent tuberculosis. The incidence of tuberculosis was found to trend downward in Brazil, whereas it trended upward worldwide. Tuberculosis incidence rates correlated positively with poverty rates and with HIV incidence rates. CONCLUSIONS: Social inequality and the advent of AIDS are the major factors that aggravate the current situation of tuberculosis. In this context, methodical approaches to the assessment of surveillance activities are welcome, because they will identify situations in which the reported tuberculosis data do not reflect the true incidence of this disease.

    We attempted a stochastic study of cancer risk change in time using the follow-up data of the age-adjusted incidence rate (AAIR) of cancer in Japan, which covered 13 neoplasia types of both sexes in scope, and ranged from 1975 to 1993 in time. The purpose of our study was to test whether or not there was any mathematical regularity that was to condition cancer risk changes in time in all the 13 human neoplasia types. We investigated the relation between 2 neoplasias as regards log AAIR changes in time by the direct successive elimination method of Gauss, a fitness test of a given pair data to an equilibrium model. The fitness test was repeated in each of 156 tumor pairs [P(13.2)] in both sexes, in each of 3 (x, y) coordinates - the original (x, y) coordinates, the rect- (x, y) coordinates and the para- (x, y) coordinates. Total number of fitness test in this study was estimated to be 156x2x3=936. The rect- (x, y) coordinates and the para- (x, y) coordinates were defined each as an (x, y) framework with its x axis crossed at a right angle to the regression line of the original log AAIR data, and as another framework with its x axis run in parallel with the regression line of the original log AAIR data. The fitness of a given tumor to an equilibrium system was assessed in terms of the correlation coefficient value r within the range of -1.000 (the oncogene-type equilibrium system) to +1.000 (the tumor suppressor gene-type equilibrium system). Results obtained are given as follows: i) the positivity rates of the fitness test to the oncogene-type equilibrium system and the tumor suppressor gene-type system in the male all-cancer population were each 95.5% (149/156 tumor pairs) and 79.5% (124/156 tumor pairs), and those in the female all-cancer population were each 91.0% (142/156 tumor pairs) and 83.3% (130/156 tumor pairs). Evidence was available to indicate that all of the 13 human neoplasia types of both sexes was associated with both oncogene activation and tumor

    The purpose of the present investigation is to elucidate the relation between the distribution pattern of the age-adjusted incidence rate (AAIR) changes in time and space of 15 tumors of bothe sexes and the locations of centers of centripetal-(oncogene type) and centrifugal-(tumoe suppressor gene type) forces. The fitness of the observed log AAIR data sets to the oncogene type- and the tumor suppressor gene type-equilibrium models and the locations of 2 force centers were calculated by applying the least square method of Gauss to log AAIR pair data series with and without topological data manipulations, which are so designed as to let log AAIR pair data series fit to 2 variant (x, y) frameworks, the Rect-coordinates and the Para-coordinates. The 2 variant (x, y) coordinates are defined each as an (x, y) framework with its X axis crossed at a right angle to the regression line of the original log AAIR data (the Rect-coordinates) and as another framework with its X axis run in parallel with the regression line of the original log AAIR pair data series (the Para-coordinates). The fitness test of log AAIR data series to either the oncogene activation type equilibrium model (r = -1.000) or the tumor suppressor gene inactivation type (r = 1.000) was conducted for each of the male-female type pair data and the female-male type data, for each of log AAIR changes in space and log AAIR changes in time, and for each of the 3 (x, y) frameworks in a given neoplasia of both sexes. The results obtained are given as follows: 1) The positivity rates of the fitness test to the oncogene type equilibrium model and the tumor suppressor gene type model were each 63.3% and 56.7% with the log AAIR changes in space, and 73.3% and 73.3% with log AAIR changes in time, as tested in 15 human neoplasias of both sexes. 2) Evidence was presented to indicate that the clearance of oncogene activation and tumor suppressor gene inactivation is the sine qua non premise of carciniogenesis. 3) The r

    Full Text Available Object. Gender and disease course specific incidences were studied in high- and medium-risk regions of MS in Finland. Methods. Age- and gender-specific incidences with 95% CIs were calculated in 10-year periods from 1981 to 2010. Poser diagnostic criteria were used and compared with the McDonald criteria from 2001 to 2010. Association between age and diagnostic delay over time was assessed by using the Kruskal-Wallis test. Results. 1419 (89% RRMS and 198 (11% PPMS cases were included. RRMS incidence increased with the female to male ratio (F/M from 4,2/105 (F/M 1.9 to 9,7 (2.3, while that of PPMS decreased from 1,2 (1.6 to 0,7 (1.2. The use of McDonald criteria did not change the conclusion. The decreasing diagnostic delay and age at diagnosis in RRMS were associated within the 10-year periods and contrasted those in PPMS. Increasing female risk in RRMS was observed in the high-risk region. Conclusion. Increasing RRMS incidence and high female ratios shown in each age group indicate gender-specific influences acting already from childhood. A more precise definition of the risk factors and their action in MS is needed to provide a better understanding of underlying pathological processes and a rationale for the development of new preventive and treatment strategies.

    Full Text Available O câncer de mama apresenta elevada incidência e mortalidade em todo o mundo, representando um grave problema de saúde pública. A incidência dessa neoplasia vem aumentando nas últimas décadas, mesmo em áreas de tradicional baixa incidência, em grande parte devido às mudanças nos hábitos de vida e no perfil epidemiológico da população. Vários países desenvolvidos têm conseguido, apesar desse aumento na incidência, reduzir a sua mortalidade, através de um diagnóstico mais precoce e de um tratamento mais eficaz. Nesse artigo comentamos as tendências atuais para o câncer de mama em vários locais do mundo, de forma comparativa, bem como os possíveis fatores envolvidos nessas mudanças. Dispensamos particular atenção à situação do Brasil, e da cidade de Goiânia.Breast cancer has the highest incidence and mortality rates in the whole World, and is a severe public health issue. This type of neoplasia has been increasing in the last decades, even in areas of traditional low incidence in part due to changes in the lifestyle and epidemiological profile of the population.

    Full Text Available Background This is a study of the epidemiology of acute and chronic episodes of care (EoCs in the Transition Project in three countries. We studied the duration of EoCs for acute and chronic health problems and the relationship of incidence to prevalence rates for these EoCs.Method The Transition Project databases collect data on all elements of the doctor–patient encounter in family medicine. Family doctors code these elements using the International Classification of Primary Care.We used the data from three practice populations to study the duration of EoCs and the ratio of incidence to prevalence for common health problems.Results We found that chronic health problems tended to have proportionately longer duration EoCs, as expected, but also a lower incidence to prevalence rate ratio than acute health problems. Thus, the incidence to prevalence index could be used to define a chronic condition as one with a low ratio, below a defined threshold.Conclusions Chronic health problems tend to have longer duration EoCs, proportionately, across populations. This result is expected, but we found important similarities and differences which make defining a problem as chronic on the basis of time rather difficult. The ratio of incidence to prevalence rates has potential to categorise health problems into acute or chronic categories, at different ratio thresholds (such as 20, 30 or 50%. It seems to perform well in this study of three family practice populations, and is proposed to the scientific community for further evaluation.

    AIMS: Approximately 20% of deaths from adverse events are related to medication incidents, costing the NHS an additional £500 million annually. Less than 5% of adverse events are reported. This study aims to assess the reporting rate of medication incidents in NHS facilities in the north east of Scotland, and to describe the types and outcomes of reported incidents among different services. Furthermore, we wished to quantify the proportion of reported incidents according to the reporters\\' profession. METHODS: A retrospective description was made of medication incidents reported to an online reporting system (DATIX) over a 46-month-period (July 2005 to April 2009). Reports originated from acute and community hospitals, mental health, and primary care facilities. RESULTS: Over the study period there were 2,666 incidents reported with a mean monthly reporting rate of 78.2\\/month (SD±16.9). 6.1% of all incidents resulted in harm, with insulin being the most commonly implicated medication. Nearly three-quarters (74.2%, n=1,978) of total incidents originated from acute hospitals. Administration incidents were implicated in the majority of the reported medication incidents (59%), followed by prescribing (10.8%) and dispensing (9.9%), while the nondescript "other medication incidents" accounted for 20.3% of total incidents. The majority of reports were made by nursing and midwifery staff (80%), with medical and dental professionals reporting the lowest number of incidents (n=56, 2%). CONCLUSIONS: The majority of medication incidents in this study were reported by nursing and midwifery staff, and were due to administration incidents. There is a clear need to elucidate the reasons for the limited contribution of the medical and dental professionals to reporting medication incidents.

    The aim of this study was to analyze trends in the incidence of skin cancer worldwide, in Europe, and in Spain between 1978 and 2007. Skin cancer incidence and trends for the period 1978 to 2007 were investigated using the age- and sex-standardized rates (per 100,000 population) published in the Cancer Incidence in Five Continents series. The incidence of cutaneous melanoma increased progressively from 1978 to 2002 but decreased in the last period analyzed (2003-2007). The highest rates were reported for Australia and the white population in Hawaii. In Spain, the incidence of melanoma tripled in both sexes over the study period. The incidence of nonmelanoma skin cancer also increased between 1978 and 2007, and higher rates were detected in men. The highest incidence rates were recorded in Australia, Brazil, and among the European inhabitants of Zimbabwe. In Spain, the incidence of nonmelanoma skin cancer had doubled or tripled in both sexes by the end of the study period. We were unable to analyze data for the period 2008 to 2012 due to a 5-year delay in the publication of data by the International Agency for Research on Cancer. The rise in the incidence of skin cancer, assessed using age-standardized rates, suggests that primary prevention measures are insufficient or inappropriate. The reduction in the incidence of cutaneous melanoma in Australia between 2003 and 2007 suggests that the preventive strategies initiated several decades earlier in that country have been effective.

    The global burden of colorectal cancer (CRC) is expected to increase by 60% to more than 2.2 million new cases and 1.1 million deaths by 2030. In this study, we aim to describe the recent CRC incidence and mortality patterns and trends linking the findings to the prospects of reducing the burden through cancer prevention and care. Estimates of sex-specific CRC incidence and mortality rates in 2012 were extracted from the GLOBOCAN database. Temporal patterns were assessed for 37 countries using data from Cancer Incidence in Five Continents (CI5) volumes I-X and the WHO mortality database. Trends were assessed via the annual percentage change using joinpoint regression and discussed in relation to human development levels. CRC incidence and mortality rates vary up to 10-fold worldwide, with distinct gradients across human development levels, pointing towards widening disparities and an increasing burden in countries in transition. Generally, CRC incidence and mortality rates are still rising rapidly in many low-income and middle-income countries; stabilising or decreasing trends tend to be seen in highly developed countries where rates remain among the highest in the world. Patterns and trends in CRC incidence and mortality correlate with present human development levels and their incremental changes might reflect the adoption of more western lifestyles. Targeted resource-dependent interventions, including primary prevention in low-income, supplemented with early detection in high-income settings, are needed to reduce the number of patients with CRC in future decades.

    Full Text Available Aedes aegypti is the primary vector of the four serotypes of dengue virus (DENV1-4, Chikungunya and yellow fever virus to humans. Previous population genetic studies have revealed a particular genetic structure among the vector populations in the Americas that suggests differences in the ability to transmit DENV. In Colombia, despite its high epidemiologic importance, the genetic population structure and the phylogeographic depiction of Ae. aegypti, as well as its relationship with the epidemiologic landscapes in cities with heterogeneous incidence levels, remains unknown. We conducted a spatiotemporal analysis with the aim of determining the genetic structure and phylogeography of Colombian populations of Ae. aegypti among cities with different eco-epidemiologic characteristics with regard to DENV.Mitochondrial cytochrome oxidase C subunit 1 (COI--NADH dehydrogenase subunit 4 (ND4 genes were sequenced and analyzed from 341 adult mosquitoes collected during 2012 and 2013 in the Colombian cities of Bello, Riohacha and Villavicencio, which exhibit low, medium and high levels of incidence of DENV, respectively.

    Aedes aegypti is the primary vector of the four serotypes of dengue virus (DENV1-4), Chikungunya and yellow fever virus to humans. Previous population genetic studies have revealed a particular genetic structure among the vector populations in the Americas that suggests differences in the ability to transmit DENV. In Colombia, despite its high epidemiologic importance, the genetic population structure and the phylogeographic depiction of Ae. aegypti, as well as its relationship with the epidemiologic landscapes in cities with heterogeneous incidence levels, remains unknown. We conducted a spatiotemporal analysis with the aim of determining the genetic structure and phylogeography of Colombian populations of Ae. aegypti among cities with different eco-epidemiologic characteristics with regard to DENV. Mitochondrial cytochrome oxidase C subunit 1 (COI)--NADH dehydrogenase subunit 4 (ND4) genes were sequenced and analyzed from 341 adult mosquitoes collected during 2012 and 2013 in the Colombian cities of Bello, Riohacha and Villavicencio, which exhibit low, medium and high levels of incidence of DENV, respectively. The results demonstrated a low genetic differentiation over time and a high genetic structure between the cities due to changes in the frequency of two highly supported genetic groups. The phylogeographic analyses indicated that one group (associated with West African populations) was found in all the cities throughout the sampling while the second group (associated with East African populations) was found in all the samples from Bello and in only one sampling from Riohacha. Environmental factors such as the use of chemical insecticides showed a significant correlation with decreasing genetic diversity, indicating that environmental factors affect the population structure of Ae. aegypti across time and space in these cities.

    Sediments containing natural gas hydrates occur worldwide on continental and insular slopes and rises of active and passive margins, on continental shelves of polar regions, and in deep-water (> 300 m) environments of inland lakes and seas. The potential amount of methane in natural gas hydrates is enormous, with current estimates at about 1019 g of methane carbon. Subaquatic gas hydrates have been recovered in 14 different areas of the world, and geophysical and geochemical evidence for them has been found in 33 other areas. The worldwide distribution of natural gas hydrates is updated here; their global importance to the chemical and physical properties of near-surface subaquatic sediments is affirmed. ?? 1993 Springer-Verlag.

    Estimates of the worldwide incidence and mortality from 27 cancers in 2008 have been prepared for 182 countries as part of the GLOBOCAN series published by the International Agency for Research on Cancer. In this article, we present the results for 20 world regions, summarizing the global patterns for the eight most common cancers. Overall, an estimated 12.7 million new cancer cases and 7.6 million cancer deaths occur in 2008, with 56% of new cancer cases and 63% of the cancer deaths occurring in the less developed regions of the world. The most commonly diagnosed cancers worldwide are lung (1.61 million, 12.7% of the total), breast (1.38 million, 10.9%) and colorectal cancers (1.23 million, 9.7%). The most common causes of cancer death are lung cancer (1.38 million, 18.2% of the total), stomach cancer (738,000 deaths, 9.7%) and liver cancer (696,000 deaths, 9.2%). Cancer is neither rare anywhere in the world, nor mainly confined to high-resource countries. Striking differences in the patterns of cancer from region to region are observed.

    Purpose: Although the carcinogenic effect of ionizing radiation is well known, knowledge gaps persist on the health effects of low-dose radiation, especially in children. The cancer incidence rate in a cohort of 92,957 children diagnosed using X-rays in the years 1976-2003 in the radiology department of a large university clinic was studied. Materials and Methods: Individual radiation doses per examination were reconstructed using an algorithm taking into account the dose area product and other exposure parameters together with conversion factors computed specifically for the equipment and protocols used in the radiology department. Incident cancer cases in the period 1980-2006 were identified via record linkage to the German Childhood Cancer Registry using pseudonymized data. Results: A total of 87 cancers occurred in the cohort between 1980 and 2006: 33 leukemia, 13 lymphoma, 10 brain tumors, and 31 other tumors. The standardized incidence ratio (SIR) for all cancers was 0.99 (95 % CI: 0.79 1.22). A dose-response relationship was not observed for all cancers, leukemia and lymphoma or solid tumors. The cancer risks for boys and girls did not differ. Conclusion: No increase in the cancer incidence risk in relation to very low doses of diagnostic ionizing radiation was observed in this study. However, the results are compatible with a broad range of risk estimates. (orig.)

    Long-term sick-leave is a major public health problem, but data on its incidence in Japan are scarce. We aimed to present reference data for long-term sick-leave among private sector employees in Japan. The study population comprised employees of 12 companies that participated in the Japan Epidemiology Collaboration on Occupational Health Study. Details on medically certified sick-leave lasting ≥30 days were collected from each company. Age- and sex-specific incidence rate of sick-leave was calculated for the period of April 2012 to March 2014. A total of 1422 spells in men and 289 in women occurred during 162,989 and 30,645 person-years of observation, respectively. The three leading causes of sick-leave (percentage of total spells) were mental disorders (52%), neoplasms (12%), and injury (8%) for men; and mental disorders (35%), neoplasms (20%), and pregnancy-related disease (14%) for women. Incidence rate of sick-leave due to mental disorders was relatively high among men in their 20s-40s but tended to decrease with age among women. Incidence rate of sick-leave due to neoplasms started to increase after age 50 in men and after age 40 in women, making neoplasms the leading cause of sick-leave after age 50 for women and after age 60 for men and the second leading cause after age 40 for women and after age 50 for men. Pregnancy-related disease was the second leading cause of sick-leave among women aged 20-39 years. These results suggest that mental disorder, neoplasms, and pregnancy-related disease are the major causes of long-term sick-leave among private sector employees in Japan.

    Macintosh, Janelle L B; Eden, Lacey M; Luthy, Karlen E; Schouten, Aimee E

    Immunizations are one of the most important health interventions of the 20th century, yet people in many areas of the world do not receive adequate immunizations. Approximately 3 million people worldwide die every year from vaccine-preventable diseases; about half of these deaths are young children and infants. Global travel is more common; diseases that were once localized now can be found in communities around the world. Multiple barriers to immunizations have been identified. Healthcare access, cost, and perceptions of safety and trust in healthcare are factors that have depressed global immunization rates. Several global organizations have focused on addressing these barriers as part of their efforts to increase immunization rates. The Bill and Melinda Gates Foundation, The World Health Organization, and the United Nations Children's Emergency Fund each have a part of their organization that is concentrated on immunizations. Maternal child nurses worldwide can assist in increasing immunization rates. Nurses can participate in outreach programs to ease the burden of patients and families in accessing immunizations. Nurses can work with local and global organizations to make immunizations more affordable. Nurses can improve trust and knowledge about immunizations in their local communities. Nurses are a powerful influence in the struggle to increase immunization rates, which is a vital aspect of global health promotion and disease prevention.

    Breast cancer is the most common malignancy in women worldwide and its incidence is generally increasing. In 2012, it was the second most common cancer in the world. It is necessary to obtain information on incidence and mortality for health planning. This study aimed to investigate the relationship between the human development index (HDI), and the incidence and mortality rates of breast cancer in the world in 2012. This ecologic study concerns incidence rate and standardized mortality rates of the cancer from GLOBOCAN in 2012, and HDI and its components extracted from the global bank site. Data were analyzed using correlation tests and regression with SPSS software (version 15). Among the six regions of WHO, the highest breast cancer incidence rate (67.6) was observed in the PAHO, and the lowest incidence rate was 27.8 for SEARO. There was a direct, strong, and meaningful correlation between the standardized incidence rate and HDI (r=0.725, p≤0.001). Pearson correlation test showed that there was a significant correlation between age-specific incidence rate (ASIR) and components of the HDI (life expectancy at birth, mean years of schooling, and GNP). On the other, a non-significant relationship was observed between ASIR and HDI overall (r=0.091, p=0.241). In total, a significant relationship was not found between age-specific mortality rate (ASMR) and components of HDI. Significant positive correlations exist between ASIR and components of the HDI. Socioeconomic status is directly related to the stage of the cancer and patient's survival. With increasing the incidence rate of the cancer, mortality rate from the cancer does not necessariloy increase. This may be due to more early detection and treatment in developed that developing countries. It is necessary to increase awareness of risk factors and early detection in the latter.

    The aim of this study was to identify trends in the incidence of lung cancer in the Leon Healthcare Area. All cases of cancer among residents of the Leon healthcare catchment area listed in the hospital-based tumor registry of the Centro Asistencial Universitario de Leon (CAULE) between 1996 and 2010 were included. Gross incidence rates over 3-year intervals were calculated and adjusted for the worldwide and European populations. A total of 2,491 cases were included. In men, incidence adjusted for the European population rose from 40.1 new cases per 100,000 population (1996-1998) to 61.8 (2005-2007), and then fell to 54.6 (2008-2010). In women, incidence tripled from 3.0 (1996-1998) to 9.2 new cases per 100,000 (2008-2010). Although lung cancer is an avoidable disease, it is a serious problem in the Leon Healthcare Area. Of particular concern is the rising incidence among women. Copyright © 2015 SEPAR. Published by Elsevier Espana. All rights reserved.

METHODS: All sixty-one incident cases were located temporally (day of diagnosis and spatially (place of residence in the area of study. Knox's method was used to assess spatio-temporal clustering of incident cases. RESULTS: The overall incidence rate of type 1 diabetes was 4.11 cases per 100,000 children aged less than 15 years per year (95% confidence interval: 3.06--5.14. The incidence rate seems to have increased since the last estimate of the incidence calculated for the years 1986--1992 in the metropolitan region of Santiago. Different combinations of space-time intervals have been evaluated to assess spatio-temporal clustering. The smallest p-value was found for the combination of critical distances of 750 meters and 60 days (uncorrected p-value = 0.048. CONCLUSIONS: Although these are preliminary results regarding space-time clustering in Santiago, exploratory analysis of the data method would suggest a possible aggregation of incident cases in space-time coordinates.OBJETIVO: Estimar a taxa de incidência de diabetes tipo 1 na área urbana de Santiago, Chile, entre os dias 21 de março de 1997 e 20 de março 1998, assim como a avaliação do agrupamento espaço-temporal dos casos incidentes no período.

    Research into the origins of food plants has led to the recognition that specific geographical regions around the world have been of particular importance to the development of agricultural crops. Yet the relative contributions of these different regions in the context of current food systems have not been quantified. Here we determine the origins (‘primary regions of diversity’) of the crops comprising the food supplies and agricultural production of countries worldwide. We estimate the degree to which countries use crops from regions of diversity other than their own (‘foreign crops’), and quantify changes in this usage over the past 50 years. Countries are highly interconnected with regard to primary regions of diversity of the crops they cultivate and/or consume. Foreign crops are extensively used in food supplies (68.7% of national food supplies as a global mean are derived from foreign crops) and production systems (69.3% of crops grown are foreign). Foreign crop usage has increased significantly over the past 50 years, including in countries with high indigenous crop diversity. The results provide a novel perspective on the ongoing globalization of food systems worldwide, and bolster evidence for the importance of international collaboration on genetic resource conservation and exchange.

    Fuel cell technologies for stationary power are set to play a role in power generation applications worldwide. The worldwide fuel cell vision is to provide powerplants for the emerging distributed generation and on-site markets. Progress towards commercialization has occurred in all fuel cell development areas. Around 100 ONSI phosphoric acid fuel cell (PAFC) units have been sold, with significant foreign sales in Europe and Japan. Fuji has apparently overcome its PAFC decay problems. Industry-driven molten carbonate fuel cell (MCFC) programs in Japan and the U.S. are conducting megawatt (MW)-class demonstrations, which are bringing the MCFC to the verge of commercialization. Westinghouse Electric, the acknowledged world leader in tubular solid oxide fuel cell (SOFC) technology, continues to set performance records and has completed construction of a 4-MW/year manufacturing facility in the U.S. Fuel cells have also taken a major step forward with the conceptual development of ultra-high efficiency fuel cell/gas turbine plants. Many SOFC developers in Japan, Europe, and North America continue to make significant advances.

    Noroviruses (Norwalk-like viruses) are recognized as major causes of acute gastroenteritis worldwide. Outbreaks of norovirus gastroenteritis are often associated with consumption of oysters. In this study, oysters imported into Hong Kong from 11 countries over a 3-year period were screened by RT-PCR. Overall, 53 out of 507 (10.5%) samples were positive for norovirus-RNA, and a wide variety of strains were found. Two novel genetic clusters were detected, which could indicate novel human or animal norovirus strains. However, whether these two new clusters are of human or animal origin is not known. Thirteen outbreaks, in which oysters were implicated as the source of infection were investigated: Norovirus RNA sequences could be detected in oysters from six outbreaks, but only in one outbreak the strains isolated from patients and oysters matched (>98% homology). Therefore, RT-PCR was of use in detecting norovirus contamination of oysters implicated in an outbreak, but was less useful in demonstrating an actual molecular epidemiological link with human cases. It was shown that contamination by noroviruses could be demonstrated in oysters worldwide, and therefore oysters may serve as an important vehicle for introducing novel norovirus strains.

  18. The nursing shortage: a worldwide problem

    Directory of Open Access Journals (Sweden)

    Rachel Z. Booth

    Full Text Available A worldwide shortage of nurses has been acknowledged by the multidisciplinary Global Advisory Group of the World Health Organization. The shortage is caused by an increased demand for nurses, while fewer people are choosing nursing as a profession and the current nurses worldwide are aging. The shortage applies to nurses in practice as well as the nurse faculty who teach students. The inter-country recruitment and migration of nurses from developing countries to developed countries exacerbates the problem. Although public opinion polls identifies the nurse as the person who makes the health care system work for them, the conditions of the work environment in which the nurse functions is unsatisfactory and must change. Numerous studies have shown the positive effects on the nurse of a healthy work environment and the positive relationships between nursing care and patient outcomes. It is important that government officials, insurance companies, and administrators and leaders of health care systems acknowledge and operationalize the value of nurses to the health care system in order to establish and maintain the integrity and viability of that system.

    Full Text Available A worldwide shortage of nurses has been acknowledged by the multidisciplinary Global Advisory Group of the World Health Organization. The shortage is caused by an increased demand for nurses, while fewer people are choosing nursing as a profession and the current nurses worldwide are aging. The shortage applies to nurses in practice as well as the nurse faculty who teach students. The inter-country recruitment and migration of nurses from developing countries to developed countries exacerbates the problem. Although public opinion polls identifies the nurse as the person who makes the health care system work for them, the conditions of the work environment in which the nurse functions is unsatisfactory and must change. Numerous studies have shown the positive effects on the nurse of a healthy work environment and the positive relationships between nursing care and patient outcomes. It is important that government officials, insurance companies, and administrators and leaders of health care systems acknowledge and operationalize the value of nurses to the health care system in order to establish and maintain the integrity and viability of that system.

    Previous reports have shown that overall incidence of malignant brain and other central nervous system (CNS) tumors varied significantly by country. The aim of this study was to estimate histology-specific incidence rates by global region and assess incidence variation by histology and age. Using data from the Central Brain Tumor Registry of the United States (CBTRUS) and the International Agency for Research on Cancer's (IARC) Cancer Incidence in Five Continents X (including over 300 cancer registries), we calculated the age-adjusted incidence rates (AAIR) per 100000 person-years and 95% CIs for brain and other CNS tumors overall and by age groups and histology. There were significant differences in incidence by region. Overall incidence of malignant brain tumors per 100000 person-years in the US was 5.74 (95% CI = 5.71-5.78). Incidence was lowest in Southeast Asia (AAIR = 2.55, 95% CI = 2.44-2.66), India (AAIR = 2.85, 95% CI = 2.78-2.93), and East Asia (AAIR = 3.07, 95% CI = 3.02-3.12). Incidence was highest in Northern Europe (AAIR = 6.59, 95% CI = 6.52-6.66) and Canada (AAIR = 6.53, 95% CI = 6.41-6.66). Astrocytic tumors showed the broadest variation in incidence regionally across the globe. Brain and other CNS tumors are a significant source of cancer-related morbidity and mortality worldwide. Regional differences in incidence may provide clues toward genetic or environmental causes as well as a foundation for broadening knowledge of their epidemiology. Gaining a comprehensive understanding of the epidemiology of malignant brain tumors globally is critical to researchers, public health officials, disease interest groups, and clinicians and contributes to collaborative efforts in future research.

    Background: Breast cancer is the most frequently diagnosed malignancy and the leading cause of cancer death among women worldwide. In Morocco, there have been few recent descriptive studies on female breast cancer. The aim of this study was to describe the latest available incidence and mortality rates of breast cancer among Moroccan women and to compare them with rates in other regional and Western countries. Methods: For this descriptive study, Moroccan incidence data were obtained from the most recent reports of the cancer registries of Casablanca and Rabat. Information on breast cancer incidence for different countries were obtained primarily from publicly available cancer registries and Cancer Incidence in Five Continents, Volume X. Mortality data were extracted from the GLOBOCAN 2012 published by the International Agency for Research on Cancer. Results: The age-standardized incidence (World) rate of breast cancer in Moroccan women increased from 35.0 to 39.0 per 100,000 women between 2004 and 2008, showing an annual increase of 2.85 %. The highest incidence rates were registered in the age groups of 45-49, 50-54 and 55-59 years (106.1, 108.2 and 108.5 respectively). Sixty-nine percent of female breast cancer cases were diagnosed at stages II and III. In 2012, the estimated number of women who died of breast cancer in Morocco was 2,878. The crude, age-standardized (World) mortality rates were 17.3 and 18.0 per 100,000, respectively. Conclusion: Although the incidence of female breast cancer in Morocco is lower than in Western countries, evidence shows that the rate is rising. This increase of breast cancer incidence has been observed in parallel with changes in reproductive behavior and adoption of a Western lifestyle. Prevention policies need to be implemented.

    Primary liver cancer, the most common histologic types of which are hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), is the second leading cause of cancer death worldwide. While rising incidence of liver cancer in low-risk areas and decreasing incidence in some high-risk areas has been reported, trends have not been thoroughly explored by country or by histologic type. We examined liver cancer incidence overall and by histology by calendar time and birth cohort for selected countries between 1978 and 2007. For each successive 5-year period, age-standardized incidence rates were calculated from volumes V-IX of the Cancer Incidence in Five Continents electronic database (CI5plus) and the newly released CI5X (volume X) database. Wide global variations persist in liver cancer incidence. Rates of liver cancer remain highest in Asian countries, specifically Eastern and South-Eastern Asian countries. While rates in most of these high-risk countries have been decreasing in recent years, rates in India and several low-risk countries of Africa, Europe, the Americas, and Oceania have been on the rise. Liver cancer rates by histologic type tend to convey a similar temporal profile. However, in Thailand, France, and Italy, ICC rates have increased while HCC rates have declined. We expect rates in high-risk countries to continue to decrease, as the population seroprevalence of hepatitis B virus (HBV) continues to decline. In low-risk countries, targeted screening and treatment of the hepatitis C virus (HCV), treatment of diabetes and primary prevention of obesity, will be key in reducing future liver cancer incidence. © 2016 UICC.

    To determine the incidence of type 1 diabetes mellitus (T1DM) among children aged 0-14 yr inclusive in the Canadian province of Newfoundland and Labrador (NL). Prospective and retrospective cohort study of the incidence of T1DM in children aged 0-14 yr from 1987 to 2005. Identified cases during this time period were ascertained from several sources and verified using the capture-recapture technique. Over the study period, 732 children aged 0-14 yr were diagnosed with T1DM. The incidence of T1DM in this population over the period 1987-2005 inclusive was 35.08 per 100,000 (95% confidence interval: 32.54, 37.62). The incidence over this period increased linearly at the rate of 0.78 per 100 000 per year. There was a significant difference between the incidence of 31.61 per 100,000 for boys in the 0-4-yr age-group and 19.05 per 100,000 for girls in the 0-4-yr age-group (p = 0.001). The incidence was very high throughout the entire province. The province of NL has one of the highest incidences of T1DM reported worldwide. The incidence is increasing over the 19-yr study period.

  5. Suicide in Recent Onset Psychosis Revisited: Significant Reduction of Suicide Rate over the Last Two Decades - A Replication Study of a Dutch Incidence Cohort.

    Full Text Available This study aims to compare the suicide risk over the past decade following recent onset psychosis to findings from the eighties and nineties in the same catchment area and to identify predictors of suicide in the context of the Psychosis Recent Onset Groningen-Survey (PROGR-S. A medical file search was carried out to determine the current status of all patients admitted between 2000 and 2009. The suicide rate was compared with a study executed in 1973-1988 in the same catchment area. Predictors of suicide were investigated using Cox regression. The status of 424 of the 614 patients was known in July 2014. Suicide occurred in 2.4% of patients with psychosis disorders (n = 10; mean follow-up 5.6 years; 6 out of 10 suicides took place within two years. Within two decades, the suicide rate dropped from 11% (follow-up 15 years, 8.5% after 5 years to 2.4%. The Standardized Mortality Rate (SMR of suicides compared with the general population was 41.6. A higher age was the only significant predictor for suicide. Neuroticism, living situation, disorganized and negative symptoms, and passive coping style all showed a trend for significance. A significant reduction in the suicide rate was found for people with psychosis over the past decades. Given the high SMR, suicide research should be given the highest priority. Identifying predictors may contribute to further reduction of suicide among patients with psychosis.

    Data on the incidence of deliberate self-harm (DSH) and suicide attempts (SAs) are lacking in non-Western adolescents, and no studies have investigated differences in incident DSH and SA worldwide. This study aimed to investigate the incidence rates and relationships between predictors in DSH and SA. The Taiwanese Adolescent Self-Harm Project was a longitudinal study of DSH among adolescents. We recruited 5,879 students from 14 senior high schools in northern Taiwan. Online questionnaires on sociodemographic data, suicidality, depressive symptoms, self-esteem, social support, family discord, impulsivity, and alcohol and tobacco use were assessed at baseline (T1) and at 1 year of follow-up (T2). Logistic regression analyses were performed to evaluate the predictors of incident DSH and SA. The mean age was 16.02 years, and 56.73% of the cohort was female. At T1, the lifetime prevalence rates of DSH and SA were 25.04% and 3.50%, respectively. At T2, 4,331 (73.67%) students had completed follow-up assessments. The 1-year incidence rates of DSH and SA were 4.04% and 1.53%, respectively. The predictors of incident DSH included perceived family discord and more depressive symptoms at T1. The predictors of incident SA were lifetime suicide ideation, more depressive symptoms, and tobacco use at T1. The incidence rates of DSH and SA were similar to those reported in Western countries. The predictors of incident DSH and SA were similar but not identical. Our results highlight the risk factors which should be considered in terms of early identification and intervention among adolescents to prevent suicidality.

    To investigate the incidence of isolated hematuria and its relationship to the glomerular filtration rate (GFR). Data from the Korean National Health and Nutrition Examination Survey V were used. A stratified, three-stage, clustered probability design was used to collect representative data on the Korean population. Ultimately, 18,587 participants were included. The incidence of isolated dipstick hematuria and its relationship with the GFR (estimated by the Chronic Kidney Disease Epidemiology Collaboration equation) were evaluated. The analysis showed that 31.8% of the population had isolated hematuria, the incidence of which significantly increased with age (P trend hematuria increased, the ratio of GFR hematuria group was significantly reduced compared to that of the negative, grade 1, and grade 2 hematuria groups (with an adjusted mean ± standard error of 94.0 ± 0.8 vs. 97.2 ± 0.3 ml/min/1.73 m(2), P hematuria group for a GFR hematuria groups after adjusting for the confounders (adjusted odds ratio 1.468, 95% confidence interval 1.049-2.054, P = 0.025). An effective health policy for hematuria screening is needed for older age groups. A strategy of careful checkups and counseling regarding renal function is necessary for patients with isolated hematuria.

    Around half of input data in the global burden of disease cancer collaboration (GBDCC) and GLOBOCAN projects come from low quality sources, mainly from developing countries. This may lead to loss of precision in estimates. Our question was: Are the absolute values and trends of the GBDCC and GLOBOCAN estimates for lung cancer (LC) in Iran consistent with available statistics?. Incidence and mortality statistics were extracted from national reports (N.IRs and N.MRs) and GBDCC (GBDincidence and mortality) and GLOBOCAN databases for 19902013 where available. Trends were analyzed and absolute values and annual percentage changes (APCs) were estimated and compared. Incompleteness of case ascertainment at the Iranian national cancer registry and Iranian national civil registration was assessed for better understanding. Trends of N.IRs were significantly rising for males (APC: 19.4; 95% CI: 12.526.7) and females (23.2; 16.030.8). Trends of GBDincidence were stable for males (0.2; 1.51.1) and females (1.0; 2.30.4). Absolute N.IRs were less than GBDincidence steadily except for 2009. Trend of N.MRs was increasing up to 2004, but stable thereafter. Trends of GBDmortality were also stable. Absolute N.MRs were less than GBDmortality for years up to 2003 and more than GBDmortality since 2005. The estimates of GLOBOCAN were more than N.IRs and N.MRs. The GBDCC and GLOBOCAN values for LC in Iran are underestimates. Generation of data quality indices to present along with country specific estimates is highly recommended.

    Coffee (Coffea arabica and Coffea canephora) plays a vital role in many countries' economies, providing necessary income to 25 million members of tropical countries, and supporting a $81 billion industry, making it one of the most valuable commodities in the world. At the same time, coffee is at the center of many issues of sustainability. It is vulnerable to climate change, with disease outbreaks becoming more common and suitable regions beginning to shift. We develop a statistical production model for coffee which incorporates temperature, precipitation, frost, and humidity effects using a new database of worldwide coffee production. We then use this model to project coffee yields and production into the future based on a variety of climate forecasts. This model can then be used together with a market model to forecast the locations of future coffee production as well as future prices, supply, and demand.

    To assess current nutritional practices in critically ill children worldwide. A two-part online, international survey. The first part, "the survey", was composed of 59 questions regarding nutritional strategies and protocols (July-November 2013). The second part surveyed the "point prevalence" of nutritional data of patients present in a subgroup of the responding PICUs (May-September 2014). Members of the World Federation of Pediatric Intensive and Critical Care Societies were asked to complete the survey. Pediatric critical care providers. Survey. We analyzed 189 responses from 156 PICUs in 52 countries (survey). We received nutritional data on 295 patients from 41 of these 156 responding PICUs in 27 countries (point prevalence). According to the "survey", nutritional protocols and support teams were available in 52% and 57% of the PICUs, respectively. Various equations were in use to estimate energy requirements; only in 14% of PICUs, indirect calorimetry was used. Nutritional targets for macronutrients, corrected for age/weight, varied widely. Enteral nutrition would be started early (within 24 hr of admission) in 60% of PICUs, preferably by the gastric route (88%). In patients intolerant to enteral nutrition, parenteral nutrition would be started within 48 hours in 55% of PICUs. Overall, in 72% of PICUs supplemental parenteral nutrition would be used if enteral nutrition failed to meet at least 50% of energy delivery goal. Several differences between the intended (survey) and the actual (point prevalence) nutritional practices were found in the responding PICUs, predominantly overestimating the ability to adequately feed patients. Nutritional practices vary widely between PICUs worldwide. There are significant differences in macronutrient goals, estimating energy requirements, timing of nutrient delivery, and threshold for supplemental parenteral nutrition. Uniform consensus-based nutrition practices, preferably guided by evidence, are desirable in the PICU.

    Full Text Available The tendency in recent decades for manufacturing plants of semi-finished products such as composite panels, has been to invest in order to achieve high production capacities (>2,000 m³/day for panels and >3,000 t/day for paper with one line. The trend of concentrating the primary processing capacities and manufacturing wood-based panels will continue for the next few years not only in Europe but in North and South America as well. The ten largest panel manufacturers had a combined manufacturing capacity that exceeded a third of the worldwide production capacity. The financial crisis that started in 2008 has caused the closure of a large number of factories especially in North America and Central Europe. Small- and medium-sized producers will only survive if they will continue to specialize in the manufacture of panel types and sizes (niche products that are “unprofitable” for mega-groups. The installed production capacity worldwide of all wood-based composite panels combined (includes PY, PB, MDF, OSB rose by more than 2.5 times between 1980 and 2005 (225 mil.m³, and continues to increase despite the crises reaching approx. 300 mil.m³ in 2013. The forecast for the coming years varies greatly from continent to continent. In North America and Central Europe, both a consolidation of the available production capacities and the closure of less efficient older lines are expected. The lowest point of the effect of the financial crisis on the building industry seems to have been overcome. The furniture production companies will continue to move from one continent and region to another.

Objectives: To review the epidemiological indicators of SCI, such as incidence, prevalence, demographic characteristics, etiology, level and severity of injury, complications and mortality. Setting: The Department of Orthopaedics, Tianjin Medical University General Hospital, ­Heping District, Tianjin, People’s Republic of China. Methods: We searched articles published in PubMed, Medline, EMBASE and the Web of ­Science between January 1993 and June 2017 using the key words “spinal cord injury”, “­traumatic spinal cord injury”, “non-traumatic spinal cord injury” and “epidemiology”. The incidence, etiology, prevalence, patient demographics, level and severity of injury, complications and mortality were reviewed from the articles. Results: The epidemiology of SCI has changed. Motor vehicle accidents and falls have become the most common reasons of injury gradually. Incidence of SCI varies by regions or countries, and it has gradually increased with the expansion of human activities. The number of male patients were significantly more than female, the average age of patients with SCI had a tendency to increase gradually. The cervical level of spine was the most common part of injury; there were more number of patients with tetraplegia than patients with paraplegia. Electrolyte disturbances, pulmonary infections, urinary tract infections and bedsores were the four most common complications. Conclusion: We must have a greater

    2017-06-01

    Internationally, ovarian cancer is the 7th leading cancer diagnosis and 8th leading cause of cancer mortality among women. Ovarian cancer incidence varies by region, particularly when comparing high vs. low-income countries. Temporal changes in reproductive factors coupled with shifts in diagnostic criteria may have influenced incidence trends of ovarian cancer and relative rates by histologic subtype. Accordingly, we evaluated trends in ovarian cancer incidence overall (1973-1977 to 2003-2007) and by histologic subtype (1988-1992 to 2003-2007) using volumes IV-IX of the Cancer Incidence in Five Continents database (CI5plus) and CI5X (volume X) database. Annual percent changes were calculated for ovarian cancer incidence trends, and rates of histologic subtypes for individual countries were compared to overall international incidence. Ovarian cancer incidence rates were stable across regions, although there were notable increases in Eastern/Southern Europe (e.g., Poland: Annual Percent Change (APC) 1.6%, p = 0.02) and Asia (e.g., Japan: APC 1.7%, p = 0.01) and decreases in Northern Europe (e.g., Denmark: APC -0.7%, p = 0.01) and North America (e.g., US Whites: APC -0.9%, p histologic subtypes were similar across countries, except for Asian nations, where clear cell and endometrioid carcinomas comprised a higher proportion of the rate and serous carcinomas comprised a lower proportion of the rate than the worldwide distribution. Geographic variation in temporal trends of ovarian cancer incidence and differences in the distribution of histologic subtype may be partially explained by reproductive and genetic factors. Thus, histology-specific ovarian cancer should continue to be monitored to further understand the etiology of this neoplasm. © 2017 UICC.

  18. Lightning incidents in Mongolia

    Full Text Available This is one of the first studies that has been conducted in Mongolia on the distribution of lightning incidents. The study covers a 10-year period from 2004 to 2013. The country records a human death rate of 15.4 deaths per 10 million people per year, which is much higher than that of many countries with similar isokeraunic level. The reason may be the low-grown vegetation observed in most rural areas of Mongolia, a surface topography, typical to steppe climate. We suggest modifications to Gomes–Kadir equation for such countries, as it predicts a much lower annual death rate for Mongolia. The lightning incidents spread over the period from May to August with the peak of the number of incidents occurring in July. The worst lightning affected region in the country is the central part. Compared with impacts of other convective disasters such as squalls, thunderstorms and hail, lightning stands as the second highest in the number of incidents, human deaths and animal deaths. Economic losses due to lightning is only about 1% of the total losses due to the four extreme weather phenomena. However, unless precautionary measures are not promoted among the public, this figure of losses may significantly increase with time as the country is undergoing rapid industrialization at present.

Methods: A retrospective case review of 1,992 eyes (1,364 patients treated between March 2007 and January 2009 was conducted, with a follow up of over 4 years. After identifying cases of ectasia, all the patient charts were examined retrospectively for preoperative findings suggestive of forme fruste keratoconus (FFKC. Results: Five eyes of four patients with post-LASIK ectasia were identified. All eyes passed preoperative screening and received bilateral LASIK. One of the five patients developed ectasia in both eyes. Three patients retrospectively revealed preoperative topography suggestive of FFKC, while one patient had no identifiable preoperative risk factors. Upon review of all the charts, a total 69 eyes, including four of the five eyes with ectasia, were retrospectively found to have topographies suggestive of FFKC. Conclusion: We identified four cases of post-LASIK ectasia that had risk factors for FFKC on reexamination of the chart and one case of post-LASIK ectasia with no identifiable preoperative risk factors. The most conservative screening recommendations would not have precluded this patient from LASIK. The rate of purely iatrogenic post-LASIK ectasia at our center was 0.05% (1/1,992, and the total rate of post-LASIK ectasia for our entire study was 0.25% (1/398. The rate of eyes with unrecognized preoperative FFKC that developed post-LASIK ectasia was 5.8% (1/17. Keywords

    Although research on human-mediated exchanges of species has substantially intensified during the last centuries, we know surprisingly little about temporal dynamics of alien species accumulations across regions and taxa. Using a novel database of 45,813 first records of 16,926 established alien species, we show that the annual rate of first records worldwide has increased during the last 200 years, with 37% of all first records reported most recently (1970–2014). Inter-continental and inter-taxonomic variation can be largely attributed to the diaspora of European settlers in the nineteenth century and to the acceleration in trade in the twentieth century. For all taxonomic groups, the increase in numbers of alien species does not show any sign of saturation and most taxa even show increases in the rate of first records over time. This highlights that past efforts to mitigate invasions have not been effective enough to keep up with increasing globalization. PMID:28198420

    Full Text Available While foodborne illness is not traditionally tracked by race, ethnicity or income, analyses of reported cases have found increased rates of some foodborne illnesses among minority racial/ethnic populations. In some cases (Listeria, Yersinia increased rates are due to unique food consumption patterns, in other cases (Salmonella, Shigella, Campylobacter it is unclear why this health disparity exists. Research on safe food handling knowledge and behaviors among low income and minority consumers suggest that there may be a need to target safe food handling messages to these vulnerable populations. Another possibility is that these populations are receiving food that is less safe at the level of the retail outlet or foodservice facility. Research examining the quality and safety of food available at small markets in the food desert environment indicates that small corner markets face unique challenges which may affect the quality and potential safety of perishable food. Finally, a growing body of research has found that independent ethnic foodservice facilities may present increased risks for foodborne illness. This review of the literature will examine the current state of what is known about foodborne illness among, and food safety risks for, minority and low socioeconomic populations, with an emphasis on the United States and Europe.

    A survey was conducted to quantify incidence of Beef Quality Assurance (BQA)-related defects in market beef and dairy cows and bulls selling at auction during 2 seasons in 2008. Twenty-three BQA-related traits were evaluated by 9 trained personnel during sales at 10 livestock auction markets in Idaho (n = 5; beef and dairy), California, (n = 4; dairy only), and Utah (n = 1; beef and dairy). Overall, 18,949 unique lots (8,213 beef cows, 1,036 beef bulls, 9,177 dairy cows, and 523 dairy bulls,) consisting of 23,479 animals (9,299 beef cows, 1,091 beef bulls, 12,429 dairy cows, and 660 dairy bulls) were evaluated during 125 sales (64 spring, 61 fall) for dairy and 79 sales (40 spring, 39 fall) for beef. The majority of market beef cows and bulls (60.9 and 71.3%, respectively) were predominantly black-hided, and the Holstein hide pattern was observed in 95.4 and 93.6% of market dairy cows and bulls, respectively. Market cattle weighed 548 ± 103.6 kg (beef cows), 751 ± 176.1 kg (beef bulls), 658 ± 129.7 kg (dairy cows), and 731 ± 150.8 kg (dairy bulls). Most beef cows (79.6%) weighed 455 to 726 kg, and most beef bulls (73.8%) weighed 545 to 954 kg, respectively. Among market beef cattle, 16.0% of cows and 14.5% of bulls weighed less than 455 and 545 kg, respectively, and 63.7% of dairy cows and 81.5% of dairy bulls weighed 545 to 817 kg or 545 to 954 kg, respectively. However, 19.5% of dairy cows and 13.1% of dairy bulls weighed less than 545 kg. Mean BCS for beef cattle (9-point scale) was 4.7 ± 1.2 (cows) and 5.3 ± 0.9 (bulls), and for dairy cattle (5-point scale) was 2.6 ± 0.8 (cows) and 2.9 ± 0.6 (bulls). Some 16.5% of beef cows and 4.1% of beef bulls had a BCS of 1 to 3, whereas 34.8% of dairy cows and 10.4% of dairy bulls had a BCS of 2 or less. Emaciation (beef BCS = 1, dairy BCS = 1.0) or near-emaciation (beef BCS = 2, dairy BCS = 1.5) was observed in 13.3% of dairy cows and 3.9% of beef cows. Among beef cattle, 15.1% of cows and 15.4% of bulls were

    Worldwide data on terrorist incidents between 1968 and 2004 gathered by the RAND corporation and the Oklahoma City National Memorial Institute for the Prevention of Terrorism (MIPT) were assessed for patterns and trends in morbidity/mortality. Adjusted data analyzed involve a total of 19,828 events, 7,401 ''adverse'' events (each causing {ge}1 victim), and 86,568 ''casualties'' (injuries) of which 25,408 were fatal. Most terror-related adverse events, casualties and deaths involved bombs and guns. Weapon-specific patterns and terror-related risk levels in Israel (IS) have differed markedly from those of all other regions combined (OR). IS had a fatal fraction of casualties about half that of OR, but has experienced relatively constant lifetime terror-related casualty risks on the order of 0.5%--a level 2 to 3 orders of magnitude more than those experienced in OR that increased {approx}100-fold over the same period. Individual event fatality has increased steadily, the median increasing from 14 to 50%. Lorenz curves obtained indicate substantial dispersion among victim/event rates: about half of all victims were caused by the top 2.5% (or 10%) of harm-ranked events in OR (or IS). Extreme values of victim/event rates were approximated fairly well by generalized Pareto models (typically used to fit to data on forest fires, sea levels, earthquakes, etc.). These results were in turn used to forecast maximum OR- and IS-specific victims/event rates through 2080, illustrating empirically based methods that could be applied to improve strategies to assess, prevent and manage terror-related risks and consequences.

    Full Text Available Purpose. The paper analyzes the state of water management in Ukraine and worldwide, as well as the best practices in this area. Methodology. The study was carried out based on the analysis of literature sources and reporting data on the state of water management in Ukraine, European countries, the USA (2010-2016. Findings. The water state analysis in the regions of Ukraine showed that the quality in most cases is close to or meets the requirements for drinking water. Drinking tap water requires post-treatment in all regions of the country. The main issue for today is the production of the necessary equipment for treatment plants. Unfortunately, not all equipment is produced in Ukraine. The condition of rural water pipelines is of particular concern. Among the tested pipelines 7.3% do not comply with the rules and regulations. At the same time, only 25% of villages in Ukraine are provided with centralized water supply. Originality. The authors presented the results of a comprehensive review of the world's issues on disinfection of drinking and waste water, where various methods are used, partly in combination with each other in Ukraine and the worldwide. The main unresolved issue today is the issue of the residual quantity of drugs in the drinking water. The main environmental threat of the world scale is the presence of medicines in drinking water. The treatment facilities are not suitable for the decomposition or trapping of medicinal products. Nowhere in the world there is protection from these substances. One of the key issues in the solution of drinking water production is seawater desalination. To reduce the cost of desalination of sea water the SWRO-membrane technology is used. Practical value. Water problems are number one problems all over the world and in Ukraine as well. It is necessary to provide for additional financing to solve problems in the preparation and purification of waters, not with whatever funds remain, taking into

    Full Text Available Introduction: Understanding the epidemiology of Esophageal Cancer (EC seems to be essential in order to plan and control it. The aim of this study was to investigate the incidence and mortality rate of EC and its relationship with the worldwide Human Development Index (HDI of 2012. Methods: This study was an ecological study which assessed the correlation of age-standardized incidence rate (ASIR and age-standardized mortality rate (ASMR of EC with HDI and its components. ASIR and ASMR data for EC were extracted from the global cancer project for the year 2012. Statistical analyses were performed by SPSS 16. Results: From EC were recorded worldwide in 2012, there was a total of 455,784 incidents of EC (70.86% males and 29.14% females; ratio of males to females was 2.43:1 and 400,169 mortalities (70.27% males and 29.73% females; ratio of males to females was 2.36:1. The correlation between HDI and SIR was -0.121 (p=0.105; with -0.061 (p=0.415 for men and -0.190 (p=0.010 for women. Moreover, the correlation between HDI and SMR was -0.156 (p=0.036, with -0.101 (p=0.180 for men and -0.218 (p=0.003 for women. Conclusion: The incidence and mortality rates from EC is higher in less developed or developing countries. No statistically significant correlation was seen between the standardized mortality or incidence rates of EC and the 2012 HDI.

    Background To study and update the provincial incidence of type 1 diabetes mellitus (T1DM) in Newfoundland and Labrador (NL), a province of Canada with a very high incidence previously reported in 2006, and one of the highest incidences reported worldwide. This is a retrospective time trend study of the incidence of T1DM, in children aged 0–14 years from 1987–2010 inclusive. Findings Over the study period 931 children aged 0–14 years were diagnosed with T1DM. The incidence of T1DM in this population over the period 1987 – 2010 inclusive was 37.7 per 100,000 per year (95% CI 35. 3, 40.2) The incidence from 2007–2010 was 49.9 per 100,000 per year (95% CI 42.2, 57.6). The incidence over this 24 year period increased by a factor of 1.03 per 100,000 per year. Conclusion NL has one of the highest incidences of T1DM reported worldwide. Potential reasons for the very high incidence could be related to the unique genetic background of the population, northern latitude and vitamin D insufficiency, low breastfeeding rates, and high rates of cesarean section.

  11. Incident reporting.

    Science.gov (United States)

    Wilson, J

    Healthcare delivery is a risky business. People view the NHS in the same light as other commercial businesses such as the hotel, retail and airline industries. The White Paper 'The New NHS: Modern, Dependable' (Secretary of State for Health, 1997) places statutory responsibilities on managers and clinicians to provide a quality service and to have accountability for clinical governance and performance management. Quality and risk are two sides of the same coin, i.e. if you have good quality you have low risk, and this firmly supports the clinical effectiveness agenda. Healthcare organizations in all sectors of care delivery need to demonstrate their high levels of achievement and commitment to continuous quality improvements. Risk management is a process for identifying, assessing and evaluating risks which have adverse effects on the quality, safety and effectiveness of service delivery, and taking positive action to eliminate or reduce them. Having an open, honest and blame-free organization which is open to improving processes and systems of care is a big step towards having staff who are committed to quality and getting things right. Near-miss, incident and indicator recording and reporting are cornerstones of any quality and risk management system.

    Almost 40 years after the Agency’s founding, the IEA responsibility for ensuring access to global oil supplies is still a core mandate. Yet over the course of its history, the IEA’s responsibilities have expanded along with both the international energy economy and conceptions of energy security itself. Our mission to promote secure and sustainable energy provision spans the energy mix. At the same time, a changing global energy map means that the industrialised nations of the world no longer dominate energy consumption. The IEA must work in close co-operation with partner countries and organisations worldwide to achieve its three core objectives: energy security, economic prosperity, and environmental sustainability. Working toward international commitments to reduce greenhouse gas emissions that cause global climate change; facilitating energy technology exchange, innovation and deployment; improving modern energy access to the billions of people who are without it; bolstering both cleanliness and security through energy efficiency; and promoting flexible and functioning energy markets – these efforts complement our traditional core responsibilities of mitigating the effects of supply disruptions and improving statistical transparency.

    Poxvirus infections have been found in 230 species of wild and domestic birds worldwide in both terrestrial and marine environments. This ubiquity raises the question of how infection has been transmitted and globally dispersed. We present a comprehensive global phylogeny of 111 novel poxvirus isolates in addition to all available sequences from GenBank. Phylogenetic analysis of Avipoxvirus genus has traditionally relied on one gene region (4b core protein). In this study we have expanded the analyses to include a second locus (DNA polymerase gene), allowing for a more robust phylogenetic framework, finer genetic resolution within specific groups and the detection of potential recombination. Our phylogenetic results reveal several major features of avipoxvirus evolution and ecology and propose an updated avipoxvirus taxonomy, including three novel subclades. The characterization of poxviruses from 57 species of birds in this study extends the current knowledge of their host range and provides the first evidence of the phylogenetic effect of genetic recombination of avipoxviruses. The repeated occurrence of avian family or order-specific grouping within certain clades (e.g. starling poxvirus, falcon poxvirus, raptor poxvirus, etc.) indicates a marked role of host adaptation, while the sharing of poxvirus species within prey-predator systems emphasizes the capacity for cross-species infection and limited host adaptation. Our study provides a broad and comprehensive phylogenetic analysis of the Avipoxvirus genus, an ecologically and environmentally important viral group, to formulate a genome sequencing strategy that will clarify avipoxvirus taxonomy.

    To develop a measure of alcohol affordability (AA) and compare the AA of 65 cities worldwide. In this paper, AA is defined as the proportion of median daily income needed to buy a certain quantity of certain alcoholic beverages. The income data and the price of alcoholic beverages were drawn from the Union Bank of Switzerland survey and the Economist Intelligence Unit respectively. A large majority of cities (87.7%, n = 57) had a high level of AA. The top 20 ranking was occupied by European and American cities with Tokyo in the Western Pacific region being the exception. All cities belonging to high-income countries had high levels of AA. However, two cities with low-level AA came from low-middle-income countries instead of low-income countries. The findings have shown that alcohol consumption is highly affordable in many cities. If price policy is being considered as policy instrument of alcohol control, it is in urgent need of price adjustments. More specifically, the new emerging economies play a significant role in the world alcohol control movement because of their bright economic performance with huge population size. Further studies on AA, especially periodical monitoring and its impacts on alcohol consumption and alcohol related health problems, should be conducted so as to facilitate the formulation and evaluation price measure of alcohol control. © 2012 Australasian Professional Society on Alcohol and other Drugs.

    5.0% (2.9-7.9) to 7.9% (6.4-9.7) in women. The number of adults with diabetes in the world increased from 108 million in 1980 to 422 million in 2014 (28.5% due to the rise in prevalence, 39.7% due to population growth and ageing, and 31.8% due to interaction of these two factors). Age...... in prevalence, together with population growth and ageing, are affecting the number of adults with diabetes. METHODS: We pooled data from population-based studies that had collected data on diabetes through measurement of its biomarkers. We used a Bayesian hierarchical model to estimate trends in diabetes...... with population growth and ageing, this rise has led to a near quadrupling of the number of adults with diabetes worldwide. The burden of diabetes, both in terms of prevalence and number of adults affected, has increased faster in low-income and middle-income countries than in high-income countries. FUNDING...

    In the forefront of the Paris Climate Conference COP21 in December 2015, the WGMS and UNESCO jointly launched a glacier application for mobile devices. This new information system aims at bringing scientifically sound facts and figures on worldwide glacier changes to decision makers at governmental and intergovernmental levels as well as reaching out to the interested public. The wgms Glacier App provides a map interface based on satellite images that display all the observed glaciers in the user's proximity. Basic information is provided for each glacier, including photographs and general information on size and elevation. Graphs with observation data illustrate the glacier's development, along with information on latest principal investigators and their sponsoring agencies as well as detailed explanations of the measurement types. A text search allows the user to filter the glacier by name, country, region, measurement type and the current "health" status, i.e. if the glacier has gained or lost ice over the past decade. A compass shows the closest observed glaciers in all directions from the user's current position. Finally, the card game allows the user to compete against the computer on the best monitored glaciers in the world. Our poster provides a visual entrance point to the wgms Glacier App and, hence, provides access to fluctuation series of more than 3'700 glaciers around the world.

    The CMS Experiment at the LHC is establishing a global network of inter-connected 'CMS Centres' for controls, operations and monitoring. These support: (1) CMS data quality monitoring, detector calibrations, and analysis; and (2) computing operations for the processing, storage and distribution of CMS data. We describe the infrastructure, computing, software, and communications systems required to create an effective and affordable CMS Centre. We present our highly successful operations experiences with the major CMS Centres at CERN, Fermilab, and DESY during the LHC first beam data-taking and cosmic ray commissioning work. The status of the various centres already operating or under construction in Asia, Europe, Russia, South America, and the USA is also described. We emphasise the collaborative communications aspects. For example, virtual co-location of experts in CMS Centres Worldwide is achieved using high-quality permanently-running 'telepresence' video links. Generic Web-based tools have been developed and deployed for monitoring, control, display management and outreach.

There is a reduction in volatility, which guarantees the security of currency, as well as the increase in currency volume and the inability to estimate the profitability of bitcoins. The dynamics of the value of digital currency in US dollars over recent years has been analyzed. Improvement of attitude of many countries to the considered cryptocurrency, in particular the USA, Germany, Spain, Canada, Australia, Israel and Scandinavian countries has been identified. The reasons of Ukraine’s interest in Bitcoin have been considered. Possibilities of creation of cryptocurrency on the territory of Ukraine have been analyzed, i.e. cost of electricity for mining, the legal status of mining firms, and the attitude of the National Bank of Ukraine to the digital currency. It has been concluded that the recognition of Bitcoin by the world countries in the future will allow it to be granted the status of world-wide currency.

    Full Text Available Throughout history, various civilizations developed methodologies for the collection and disposal of human waste. The methodologies throughout the centuries have been characterized by technological peaks on the one hand, and by the disappearance of the technologies and their reappearance on the other. The purpose of this article is to trace the development of sewage collection and transport with an emphasis on toilets in ancient civilizations. Evolution of the major achievements in the scientific fields of sanitation with emphasis on the lavatory (or toilets technologies through the centuries up to the present are presented. Valuable insights into ancient wastewater technologies and management with their apparent characteristics of durability, adaptability to the environment, and sustainability are provided. Gradual steps improved the engineering results until the establishment of the contemporary toilet system, which provides a combined solution for flushing, odor control, and the sanitation of sewerage. Even though the lack of proper toilet facilities for a great percentage of the present day global population is an embarrassing fact, the worldwide efforts through millennia for the acquisition of a well-engineered toilet were connected to the cultural level of each period.

    To investigate the incidence and mortality trends of upper tract urothelial cancers (UTUC) in Victoria over the last decade. Age-adjusted incidence and mortality rates were calculated for UTUC. These were identified using data from the Victorian Cancer Registry from 2001 until 2011 based on histological diagnoses. Age at diagnosis, sex and demographical location were compared. The age-standardised incidence of UTUC remained stable from 2001 to 2011. There were 278 deaths from UTUC over this period with an overall 5-year survival rate of 32%. There was no significant difference in survival between 2001-06 and 2007-11 (30% vs 36%, respectively). Lower age at diagnosis was associated with a significant improvement in survival (P = 0.01). Sex and geographical location appeared to have no effect on survival. The 5-year survival rates for UTUC in Victoria are poor, particularly in comparison to worldwide data. In contrast to worldwide trends, the incidence of UTUC appears to be stable. No significant improvement in 5-year survival rates over the short study period was identified. These findings highlight the difficulties in managing this rare yet deadly malignancy. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

    Purpose: To investigate the psychological consequences of high-dose-rate brachytherapy with 2 fractions in 1 application under spinal/epidural anesthesia in the treatment of locally advanced cervical cancer. Methods and Materials: In 50 patients with locally advanced cervical cancer, validated questionnaires were used for prospective assessment of acute and posttraumatic stress disorder (ASD/PTSD) (Impact of Event Scale–Revision), anxiety/depression (Hospital Anxiety and Depression Scale), quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30/Cervical Cancer 24), physical functioning (World Health Organization performance status), and pain (visual analogue scale), before and during treatment and 1 week and 3 months after treatment. Qualitative interviews were recorded in open format for content analysis. Results: Symptoms of ASD occurred in 30% of patients 1 week after treatment; and of PTSD in 41% 3 months after treatment in association with this specific brachytherapy procedure. Pretreatment predictive variables explain 82% of the variance of PTSD symptoms. Helpful experiences were the support of the treatment team, psychological support, and a positive attitude. Stressful factors were pain, organizational problems during treatment, and immobility between brachytherapy fractions. Conclusions: The specific brachytherapy procedure, as performed in the investigated mono-institutional setting with 2 fractions in 1 application under spinal/epidural anesthesia, bears a considerable risk of traumatization. The source of stress seems to be not the brachytherapy application itself but the maintenance of the applicator under epidural anesthesia in the time between fractions. Patients at risk may be identified before treatment, to offer targeted psycho-social support. The patients' open reports regarding helpful experiences are an encouraging feedback for the treatment team; the reported stressful

    Clozapine remains the drug of choice for treatment-resistant schizophrenia. As a consequence of its long history and complex pharmacology, we suspected wide variation in the regulations of clozapine use across different countries. The summaries of product characteristics (SPCs) from clozapine manufacturers, as well as local and national guidelines in the following selected countries, were reviewed: China, Denmark, Ireland, Japan, The Netherlands, New Zealand, Romania, the UK and the US. Clozapine is available as tablets in all countries, as an oral suspension in all included countries, with the exception of Japan and Romania, as orally disintegrating tablets in the US and China, and as an injectable in The Netherlands. General practitioner prescribing is only available in The Netherlands, New Zealand, the UK and the US, although with some restrictions in some of the countries. In Ireland and China, clozapine is only dispensed through hospital pharmacies. Hematological monitoring is mandatory in all countries but varies substantially in frequency, e.g. in Denmark hematologic monitoring is mandatory weekly for 18 weeks, followed by monthly monitoring, compared with Japan where blood work is required weekly for 26 weeks, followed by biweekly hematologic monitoring thereafter. In most included countries, with the exception of Denmark, Romania and The Netherlands, the manufacturer provides a mandatory hematological monitoring database, and dispensing of clozapine is not permissible without acceptable white blood count and absolute neutrophil count results. Local guidelines in New Zealand recommend echocardiography and routine troponin during the initial phases of treatment with clozapine. Regulations of clozapine vary widely with regard to rules of prescribing and monitoring. A worldwide update and harmonization of these regulations is recommended.

    Adventurers and Scientists for Conservation (ASC) is a nonprofit organization that collects environmental data to catalyze conservation initiatives worldwide. Adventure athletes have the skills and motivation to reach the most remote corners of the world. ASC utilizes those skills to provide the scientific community with data while providing the outdoor community with purpose beyond the personal high of reaching a summit or rowing across an ocean. We carefully select projects, choosing partnerships that will maximize the impact of ASC volunteers. Each project must have a clear path to a tangible conservation outcome and demonstrate a clear need for our brand of volunteers. We partner with government agencies, universities, and independant reseachers to kickstart data collection efforts around the world. Last year, through a partnership with the Olympic National Forest, 20 volunteers from the Seattle area set up and monitored camera traps in an effort to survey for costal Pacific marten. Our work led to the species' listing as "critically imperiled" with NatureServe. A partnership with the inaugural Great Pacific Race, engaging trans-Pacific rowing teams, searched for microplastics in the Pacific Ocean as part of our ongoing microplastics campaign. In a multi-year partnership with the American Prairie Reserve (APR), ASC volunteer crews live and work on the Reserve collecting wildlife data year round. The data we obtain directly informs the Reserve's wildlife management decisions. On this project, our crews have safely and effectively navigated temperature extremes from -30 degrees to 100+ degrees while traveling in a remote location. We are currently scouting projects in the Okavango Delta of Botswana and the rainforest of Suriname where we will be able to cover large amounts of area in a short periord of time. ASC is at the crossroads of the adventure and coservation science communities. Our approach of answering specific questions by using highly skilled and

  6. USE OF MALE METHODS OF CONTRACEPTION WORLDWIDE.

    This article analyses male contraceptive use, both globally and for developing countries. Shares of all contraceptive use due to males are examined, in the context of female use and all use. Patterns according to wealth quintiles are analysed, as well as time trends and geographic variations. Data are drawn primarily from compilations by the UN Population Division and from the Demographic and Health Series and subjected to relatively simple statistical methods including correlation/regression applications. Contraceptive methods that men use directly, or that require their co-operation to use, including condoms, withdrawal, rhythm and male sterilization, account for one-quarter of all contraceptive use worldwide. This represents 13% of married/in-union women. Both the share and the prevalence of male methods vary widely by geography and by the four methods, as well as by quintile wealth groups. With greater wealth there is an unbroken rise for total use; among the male methods, the shares of condom use and rhythm rise by wealth quintiles, while the share of withdrawal drops. The share for male sterilization is highest in the lowest and highest wealth quintiles and dips for the middle quintiles. The overall time trend since the 1980s has been steady at one-quarter of all use involving men; moreover, the share is about the same at all levels of total use. The female-only methods continue to dominate: female sterilization, IUD, pill, injectable and implant, again with great diversity geographically. In surveys men report less total use but more condom use, while females report more injectable use. For the future the male share of one-quarter of use seems secure, with little prospect of an increase unless concerted programmatic efforts are made to expand access to male methods and promote their use as part of a broadened contraceptive method mix.

    Cesarean section has become the most performed surgery and it has been enhanced with the use of antibiotics and improvement in surgical techniques. The aim of this systematic review is to describe and clarify some historical and ethical characteristics of this surgery, pointing out some aspects about its epidemiological behavior, becoming a topic that should be treated globally, giving priority to the prevention and identification of factors that may increase the incidence rates. Today, this "epidemic" reported rates higher than fifty percent, so it is considered a worldwide public health problem. Consequently, in Mexico strategies aimed at its reduction have been implemented. However, sociocultural, economic, medicolegal and biomedical factors are aspects that may difficult this goal. As we decrease the percentage of cesarean section in nulliparous patients, we diminish the number of iterative cesarean and its associated complications. This aim must be achieved through the adherence to the guidelines which promote interest in monitoring and delivery care in health institutions of our country.

    Data on international variation in breast cancer incidence may help to identify additional risk factors. Substantially lower breast cancer rates in Asia than in North America and Western Europe are established, but differences within Asia have been largely ignored despite heterogeneity in lifestyles and environments. Mongolia's breast cancer experience is of interest because of its shared genetics but vastly different diet compared with other parts of Asia. Age-standardized breast cancer incidence and mortality rates obtained from the International Association of Cancer Registries are presented for several Asian countries. Mongolian incidence rates obtained from its cancer registry describe incidence within the country. Breast cancer incidence in Mongolia (age standardized 8.0/100,000) is almost a third of rates in China (21.6/100,000), and over five times that of Japan (42.7/100,000) and Russia (43.2/100,000). Rates within Mongolia appear to have increased slightly over the last decade and are higher in urban than rural areas (annual percentage increase of age-standardized rates from 1998 to 2005 was 3.60 and 2.57 %, respectively). The increase in breast cancer incidence with age plateaus at menopause, as in other Asian populations. Mongolia's low breast cancer
