An updated global compilation of 377 new and previously published ages indicates that granitic pegmatites range in age from Mesoarchean to Neogene and have a semi-periodic age distribution. Undivided granitic pegmatites show twelve age maxima: 2913, 2687, 2501, 1853, 1379, 1174, 988, 525, 483, 391, 319, and 72 Ma. These peaks correspond broadly with various proxy records of supercontinent assembly, including the age distributions of granites, detrital zircon grains, and passive margins. Lithium-cesium-tantalum (LCT) pegmatites have a similar age distribution to the undivided granitic pegmatites, with maxima at 2638, 1800, 962, 529, 485, 371, 309, and 274 Ma. Lithium and Ta resources in LCT pegmatites are concentrated in the Archean and Phanerozoic. While there are some Li resources from the Proterozoic, the dominantly bimodal distribution of resources is particularly evident for Ta. This distribution is similar to that of orogenic gold deposits, and has been interpreted to reflect the ...
While several plots of the aggregate age distribution suggest that firm age is exponentially distributed, we find some departures from the exponential benchmark. At the lower tail, we find that very young establishments are more numerous than expected, but they face high exit hazards. At the upper tail, the oldest firms are older than the exponential would have predicted. Furthermore, the age distribution of disaggregated industries (such as the international airline industry) is less regular and can display multimodality. Although we focused on departures from the exponential, we found that the exponential was a useful reference point and endorse it as an appropriate benchmark for future work on industrial structure. ...

Downloadable! Psychological well-being (WB) includes a person?s overall appraisal of his or her life (Global WB) and affective state (Hedonic WB), and it is considered a key aspect of the health of individuals and groups. Several cross-sectional studies have documented a relation between Global WB and age. Little is known, however, about the age distribution of Hedonic WB. It may yield a different view of aging because it is less influenced by the cognitive reconstruction inherent in Global WB measures and because it includes both positive and negative components of WB. In this study we report on both Global and Hedonic WB assessed in a 2008 telephone survey of 340,847 people in the United States. Consistent with prior studies, Global WB and positive Hedonic WB generally had U-shaped age profiles showing increasedWB after the age of 50 years. However, negative Hedonic WB variables showed distinctly different and stronger patterns: Stress and Anger steeply declined from the early 20s, Worry was elevated

Age-standardized rates may be used to compare different geographic areas or time frames to adjust for any differences in the age structure of the populations that could cause a difference in rates.. It reflects the number of events (e.g., deaths, hospitalizations) that would occur for a given population if that population had the same age distribution as the 1991 Canadian population.. Age-standardized rates have been used to make more valid comparisons than comparing crude rates. Standardization requires adjusting for the effects of varying age structures of different populations and over different periods of time. The importance of age-standardization can be illustrated by using Population X, which has a higher proportion of elderly persons than Population Y. The unadjusted or "crude" mortality rate for Population X would be significantly higher than Population Y solely because it has a higher proportion of elderly persons and the elderly have a much higher death rate than younger people. This ...
Age-Adjusted Death Rate: When comparing rates over time or across different populations, crude rates (the number of deaths per 100,000 persons) can be misleading, because differences in the age distributions of the various populations are not considered. Since death is age-dependent, the comparison of crude rates of death can be especially deceptive.. Age-adjusted rates take into account the diverse age distributions of the populations. Valid comparisons between age-adjusted rates can be made, provided the same standard population and age groups have been used in the calculation of the rates. The direct method of adjustment was used to produce the age-adjusted rates for this report. In this method, the population is first divided into reasonable homogeneous age ranges, and the age-specific rate is calculated for each age range. Then, each age-specific rate is weighted by multiplying it by the proportion of the standard population in the respective age group. The age-adjusted rate is the sum of ...
From 1980 to 2010, the crude incidence of diagnosed diabetes increased 161% from 3.3 to 8.6 per 1,000 population. Similarly, the age-adjusted incidence increased 140% from 3.5 to 8.4 per 1,000 population, suggesting that the majority of the change was not due to the aging of the population. However, from 1980 to 2010, incidence did not increase at a constant rate. Both crude and age-adjusted incidence remained unchanged in the 1980s, and then increased in the 1990s through 2010. From 2008 through 2010, both crude and age-adjusted incidence has shown little change.
I produced a methodology capable of aging the species Rana luteiventris by using a process called skeletochronology. My objective was to find out if the age of the individual could be assessed by counting the number of lines of arrested growth (LAGs) from cross-sections of the third digit of the right hind foot. After this process was refined for this particular species, seventy-four individuals were sampled in order to construct a static age distribution of a population of frogs. Samples were collected from May-August 1998 at a small pond in the Lewis and Clark County, Chessman Marshland, 10 km west of Clancy, Montana. Few individuals were found to be five years of age. The majority of the population was dispersed somewhat evenly between metamorphs, 1, 3, and 4-year-old frogs. As expected, no frogs beyond five years of age were observed. There was a notable lack of 2-year-old frogs. However, I was unable to account for the low number of 2-year-old frogs in the population.
Downloadable! This paper proposes the use of optimal grouping methods for determining the various age groups within a population. The cutoff ages for these groups, such as the age from which an individual is considered to be an older person, are then endogenous variables that depend on the entire population age distribution at any given moment. This method is first applied to the age distribution of the United States and subsequently to a group of 12 industrialized countries. The cutoff ages as well as the main indicators of aging are calculated.

A comparison between mean age theory and conventional residence time distributions over a range of quantified mixing levels was conducted using computational fluid dynamics (CFD). The system was a stirred tubular reactor. The model was validated by comparing computationally derived RTD curves with experimentally obtained RTD curves, with quantified differences less than 3%. Mixing was quantified using the Tanks-in-Series model. Mixing levels were set by varying flow rate and impeller rpm. Mean age distributions at the outlet, where experimental RTDs were measured, were very narrow for all levels of mixing studied. RTDs showed expected characteristics; a wider distribution and long decay for high mixing cases and a narrow distribution centered around the mean time for cases approaching plug flow. Mean age distributions remained substantially narrower than RTDs. RTDs and mean age distributions were measured at several locations along the length of the reactor to determine changes in characteristics of

Data analysis. The average annual incidence of cancer in Gipuzkoa for the period 1998-2002 is presented for all sites together, and also for specific sites, and expressed in rates per 100,000 persons at risk per year. Crude, agespecific and age-standardized incidence rates were calculated by gender, using the direct method and adjusted with European and World population data3. Furthermore, cumulative incidence rates were calculated for each site and gender, from birth to 65 and 75 years of age.. The cancer incidence trend for the period 1986-2002 was studied for all tumours and the most frequent sites. The general trend was quantified by applying the Poisson regression12, after adjusting for age, with separate models for men and women. In this model, a linear trend was assumed for the logarithm of the rates. Goodness of fit was assessed by devianceand its degrees of freedom. The significance level was set at 0.05. In the case of prostate cancer, the Poisson model did not fit correlated as a ...
Detrital zircon age distributions provide robust insights into past sedimentary systems, but these age distributions are often complex and multi-peaked, with sample sizes too small to confidently resolve population distributions. This limited sampling hinders existing quantitative methods for comparing detrital zircon age distributions, which show systematic dependence on the sizes of compared samples. The proliferation of detrital zircon studies motivates the development of more robust quantitative methods. We present the first attempt, to our knowledge, to infer probability model ensembles (PMEs) for samples of detrital zircon ages using a Bayesian method. Our method infers the parent population age distribution from which a sample is drawn, using a Monte Carlo approach to aggregate a representative set of probability models that is consistent with the constraints that the sample data provide. Using the PMEs inferred from sample data, we develop a new estimate of correspondence between ...
The data reported in this table are derived from the HIPE (Hospital In-Patient Enquiry) data set, which records data on discharges from all publicly funded acute hospitals. Age-standardised discharge rates by county, sex and all procedures are presented. These allow comparison of discharge rates between populations of different age composition, and also of discharge rates over time. The age-standardised discharge rate (SDR) for an area is the number of discharges (per 100,000) that would occur if that area had the same age structure as the WHO European Standard Population and the local age-specific rates for that area applied. Confidence intervals for these rates are also presented. Standardised Morbidity Ratios (SMRs) are also included. SMRs express the difference between the observed discharges in each county compared to the expected discharges if the age-specific rates of the national population applied. It is presented as a ratio. A ratio that is greater than 100 indicates that county ...

Colon cancers are thought to be an inevitable result of aging, while testicular cancers are thought to develop in only a small fraction of men, beginning in utero. These models of carcinogenesis are, in part, based upon age-specific incidence data. The specific incidence for colon cancer appears to monotonically increase with age, while that of testicular cancer increases to a maximum value at about 35 years of age, then declines to nearly zero by the age of 80. We hypothesized that the age-specific incidence for these two cancers is similar; the apparent difference is caused by a longer development time for colon cancer and the lack of age-specific incidence data for people over 84 years of age. Here we show that a single distribution can describe the age-specific incidence of both colon carcinoma and testicular cancer. Furthermore, this distribution predicts that the specific incidence of colon cancer should reach a maximum at about age 90 and then decrease. Data on the incidence of colon carcinoma

IHME research used de-identified death records from the National Center for Health Statistics (NCHS) and population counts from the U.S. Census Bureau, NCHS, and the Human Mortality Database and small area estimation models in order to estimate county-level mortality rates from all cardiovascular diseases (CVD), including ischemic heart disease, cerebrovascular disease, ischemic stroke, and other types. This dataset provides estimates for age-standardized mortality rates by CVD type and sex at the county level for each state, the District of Columbia, and the United States as a whole for 1980-2014, as well as the changes in rates for each location during this period. Also included are data on the 10 counties with the highest and lowest mortality rates for each CVD type in 2014 and the top 10 causes of death by CVD type for each county. Study results were published in JAMA in May 2017 in "Trends and patterns of geographic variations in cardiovascular mortality among US counties, ...
I assess the impact that pharmaceutical innovation had on cancer mortality in Mexico during the period 2003-2013, by investigating whether there were larger declines in the age-standardized mortality rate of cancer sites (breast, lung, colon, etc.) that were subject to more pharmaceutical innovation, controlling for changes in the age-standardized cancer incidence rate. The estimates indicate that new drugs launched during 1991-2001 reduced the age-standardized cancer mortality rate by 16%, i.e., at an average annual rate of about 1.6%. I estimate that 105,661 life-years before age 70 were gained in 2013 due to cancer drugs launched during 1991-2001, and that the cost per life-year gained was in the neighborhood of $2146. By the standards of the World Health Organization, new cancer drugs have been very cost-effective in Mexico. The contribution of cancer drug innovation to Mexican longevity growth has been valuable, but, perhaps, it could have been even larger. Only half as many new cancer drugs were
Background:Incidence rates for hepatocellular carcinoma (HCC) vary considerably by age, sex, and race/ethnicity. We assessed whether HCC among sub-groups of the population by age, sex, race/ethnicity, and birth cohort are uniform or whether they interact with each other or have changed over time. Methods:Data were from the U.S. Cancer Statistics registry. We assessed annual trends within population sub-groups and examined for secular trends in the male-to-female ratio for HCC incidence. We used joinpoint regression to compute annual percent change and average annual percent change (AAPC) and corresponding 95% confidence intervals (CIs). We also used age-period-cohort models to disentangle period and cohort effects. Results:Between 2001 and 2015, HCC rates increased in men and women ≥50 years, remained stable among women aged 40-49, but decreased among males aged 40-44 (AAPC, 2.47%; 95% CI, 3.15%, 1.80%) and 45-49 (AAPC, 3.49%; 95% CI, 4.78%, 2.17%). As a result, the male-to-female incidence ...

Over the years, the age-adjusted incidence rate due to invasive cancer has continued to decline for NJ males but has remained fairly steady for NJ females. In the total NJ population and among each racial/ethnic group, males have higher incidence rates compared to females. The age-adjusted incidence rate of total invasive cancer among NJ Black males, which has historically ranked highest for decades, is now trending below White males in recent years. For recent years, county incidence rates range from a low of 389 per 100,000 population in Hudson County to a high of 544 per 100,000 population in Gloucester County ...
Most surveillance and research efforts focus on severe violence, especially on homicides. Because less extreme forms of violence may be precursors to more extreme forms, the authors analyzed data from a national survey to describe the extent of nonfatal physical violence in the US.,The authors generated weighted national estimates from responses to a random-digit-dialed telephone survey. Respondents were asked if they had been "hit, slapped, pushed, or kicked by another person or hit with an object or weapon" in the preceding 12 months. Respondents were also asked how many times such incidents had occurred and, for the last such episode, their relationship with the perpetrator, whether they had been injured, and, if so, whether they had sought medical treatment.,The authors estimate that approximately 15 million people, or 8% of the US adult population, experienced nonfatal physical violence, as defined for this study, during a 12-month period. Male gender, the 18-24-year-old age group, never ...

Kevin Rudd is clearly smart. I take his comments about believing in "a big Australia" at face value, and I disagree with his view on this. When it comes to population growth and arguments over the economic costs of an ageing population, I am struck by the relatively shallow analysis on offer. We have hardly scratched the surface of how to deal with a different population age distribution to the 50s (to pick an arbitrary reference point).. I have had some health issues, serious enough but not life-threatening, which required me to stop work for a few years now. So far, I have supported myself from investments and savings, and with the great assistance of family and friends. The current "system" for dealing with young-ish people like me is almost all or nothing, meaning fulltime (usually 45 hours or so a week in practice, sometimes substantially more) or no-time. Return-To-Work is tricky if the thinking is based on the idea of the patient making a full and complete recovery as the only option ...

The SE estimate will be smaller for correctly paired data. If we look at the data within each sample we notice variation from one subject to the next. This information gets incorporated into the SE for the independent t-test via s1 and s2. The original reason we paired was to try to control for some of this inter-subject variation, which is not of interest in the paired design. Notice that the inter-subject variation has no influence on the SE for the paired test, because only the differences were used in the calculation. The price of pairing is smaller degrees of freedom of the T-test. However, this can be compensated with a smaller SE if we had paired correctly. Pairing is used to reduce bias and increase precision in our inference. By matching/blocking we can control variation due to extraneous variables. For example, if two groups are matched on age, then a comparison between the groups is free of any bias due to a difference in age distribution. Pairing is a strategy of design, not an ...

Objectives To examine trends in prostate cancer incidence and mortality in England and Wales between 1971 and 1998, using a newly developed and validated national cancer database and the national mortality database.. Methods Age-standardized incidence and death rates were calculated directly and trends in relative survival rates among men with prostate cancer registered during 1971-1990 were examined.. Results The annual number of new cases of prostate cancer registered in England and Wales increased by 179% between 1971 and 1993, from 6174 to 17 210. Directly age-standardized incidence rates increased by 104% between 1971 and 1993, from 29 to 59 per 100 000. The number of deaths from prostate cancer increased by 113% between 1971 and 1998, from 4027 to 8570. Directly age-standardized death rates increased by 49% between 1971 and 1995 and then decreased by 8% between 1995 and 1998, an overall increase of 38% (20 to 27 per 100 000) between 1971 and 1998. The relative survival rate for prostate ...
Mortality data (2000-2002) were obtained from National Health Statistics.. Data quality Indices were compared to those for southern Portugal22, Navarra23 and Tarn24, all included in the Cancer Incidence in Five Continents Vol. IX25.. Statistical analysis. Crude (all-ages) and age-specific rates were calculated using the population at risk for the 2000-2002 period obtained from Statistics Portugal´.26 Mean annual age-standardized rates (ASR) were computed by the direct method, based on European and World standard population numbers. Confidence intervals were estimated using Poisson approximation27. Cumulative risks were assessed for the 0 to 64 and 74 year-old parameters.. Relative risks for developing cancer in the Azores when compared to mainland Portugal have been represented by standardized rate ratios27.. Results. Incidence and relative proportions; crude and standardized rates and cumulative risks are presented in Table 1, according to cancer site (ICD-10) and sex. A total of 2,515 new ...
Cancer is the third leading cause of death in Iran following coronary heart disease and accidents. According to the estimate report from GLOBOCAN 2012, the age-standardized incidence rate (ASR) of cancers was 134 and 120 per 100,000 among males and females, respectively. The estimated mortality rate for cancer was 90.4 and 72.2 per 100,000 for males and females, respectively that shows an increase of 25.4 and 31.1 percent compared to the latest report from National Death Registry (NDR) in 2004. The most common cancer among men and women was stomach cancer (20.6%) and breast cancer (28.1%), respectively and the most common childhood cancer was leukemia.. Up-to-date and accurate cancer registry data could be one of the major determinants to control, classify, diagnose and even in the treatment of cancer cases. However, since 2009 no up-to-date formal reports from the National Cancer Registry (NCR) of Iran have been announced.. Information from the cancer registries regarding different regions of ...
When drawn as a "population pyramid," age distribution can hint at patterns of growth. A top heavy pyramid, like the one for Grant County, North Dakota, suggests negative population growth that might be due to any number of factors, including high death rates, low birth rates, and increased emigration from the area. A bottom heavy pyramid, like the one drawn for Orange County, Florida, suggests high birthrates, falling or stable death rates, and the potential for rapid population growth. But most areas fall somewhere between these two extremes and have a population pyramid that resembles a square, indicating slow and sustained growth with the birth rate exceeding the death rate, though not by a great margin.. ...

The highest risk of imported malaria in Illinois is associated with travel to countries of origin by immigrants to visit family and friends. We used Join point regression to analyze Malaria crude incidence rate (mCIR) trend from 1990 through 2013. We found join point regression a useful way to summarize mCIR trends because it connected the linear line segments over a fixed time interval (annual) and allowed characterization of the trends using the Annual Percent Change.
This report presents worldwide estimates of annual mortality from all cancers and for 18 specific cancer sites around 1985.

Of the estimated 5 million deaths from cancer excluding non-melanoma skin cancer, 56% occurred in developing...
New South Wales, Australia, has a low annual incidence of TB, but there are LGAs and population groups with higher rates of TB. In line with other studies [1, 8, 10] this study demonstrates that TB in NSW predominately occurs in people born in high incidence countries who have migrated to Australia. This study successfully identified LGAs with higher TB rates given the country of birth mix of the local population.. There were nine LGAs where higher TB rates were found in the population born in a HIC. A number of variables were explored to explain this increase. The age distribution of the HIC population was similar in the areas with higher rates compared to the other areas, but the highest differential in rates of TB across areas was found in the 5-19 year age group. This may be a result of a younger population in the sub-groups of people born in a country with very high TB rates. In developed settings TB is often associated with increasing age. The analysis indicated that the age distribution ...
CSVT has been reported to be more common among females. Similarly, it was determined to be more common among female patients at a rate of 78.9% in our study. The study reported that the male/female ratio was reported as 1:1.29 (2). The age distribution among males has a homogenous distribution. However, the 20-35 years age range is more common at a rate of 61% in female patients. This type of age distribution is thought to be caused by pregnancy and OCP intake (3). The mean age was determined as 32±11.13 in a study evaluating 51 patients (4). Similarly, the mean age was calculated as 31.3±11.2 years in our study, and the mean age of the female patients was determined as 30.7±11.1 years. Headache is the most common presenting symptom of CSVT. In one study, headache was observed at a rate of 65.5% and it was seen at a rate of 80% in another study (5,6). Similarly, the complaint on admission was headache in 89.4% of the cases in our study. Headache is usually accompanied by another symptom. In ...
European age-standardised rate (per 100,000), directly age standardised using the European standard population (2013). Please note changes from previous Health Maps Wales publications. For this release, data has been standardised using the new 2013 European Standard population. Eurostat, the statistical institute of the European Union, decided at the end of 2012 to bring the artificial European Standard population (ESP) structure up to date. The new ESP has replaced the existing 1976 ESP. This change will cause age-standardised rates to increase in most cases because the new ESP gives much greater weight to older age-groups to better reflect the ageing population. As most deaths/hospital admissions occur at older ages, mortality and admission rates will generally be higher when calculated with the 2013 ESP compared to the 1976 ESP. The data produced here is therefore not directly comparable to previous publications (which were calculated using 1976 ESP), and the newly produced figures within ...

The associations between socioeconomic variables and mortality for 41,000 adults Vietnamese followed from January 1999 to March 2008 are estimated using Coxs proportionally hazard models. Also, we use decomposition techniques to investigate the relative importance of socioeconomic factors for explaining inequality in age-standardized mortality risk. The results confirm previously found negative association between mortality and income and education, for both men and women. We also found that marital status, at least for men, explain a large and growing part of the inequality. Finally, estimation results for relative education variables suggest that there exist positive spillover of education, meaning that that higher education of ones neighbors or spouse might reduce ones mortality risk.. ...

Off the grid for the last few days.]. In Milky Way group meeting, Xue (MPIA) talked about our Kinematic Consensus project, which is starting to show promise: We look for sets of stars with observable properties consistent with having the same orbital integrals of motion. It appears to group stars even when the trial potential (we use for orbit construction) is significantly different from the true potential.. At that same meeting, I described my hopes for modeling or measuring the Milky Way star-formation history, using stellar ages derived from stellar masses on the red-giant branch. This got Dalcanton (UW) asking about the point that the age distribution of red-giant stars is not the age distribution of the disk as a whole, since different stars get onto the red-giant branch at different times and stay on for different times. This led to the question: Why I dont model the mass distribution and then transform it into a star-formation history "in post" as it were? I like it! So I will re-code ...

Using data from China, a study published Feb. 24 in JAMA found that the case-fatality rate for patients with cancer was 5.6% in a sample of 1,023 deaths among 44,672 confirmed cases.. The data are derived from a total of 72,314 case records and updated through Feb. 11, according to study authors Zunyou Wu and Jennifer McGoogan at the Chinese Center for Disease Control and Prevention in Beijing.. "The overall case-fatality rate (CFR) was 2.3% (1,023 deaths among 44,672 confirmed cases)," the authors wrote. "No deaths occurred in the group aged 9 years and younger, but cases in those aged 70 to 79 years had an 8.0% CFR and cases in those aged 80 years and older had a 14.8% CFR. No deaths were reported among mild and severe cases. "The CFR was 49% among critical cases. CFR was elevated among those with preexisting comorbid conditions-10.5% for cardiovascular disease, 7.3% for diabetes, 6.3% for chronic respiratory disease, 6.0% for hypertension, and 5.6% for cancer.. "Among the 44,672 cases, a ...
Six per cent of women in the Canadian Armed Forces say they have been sexually assaulted in the last year, according to a new survey by Statistics Canada - far above the rate in the general public in Canada.
Between 2001 and 2006, the census count of people aged 15 years and over in de facto relationships rose by 25% from 951,500 to 1,193,400. This was marginally lower than the increase between 1996 and 2001 (28%). In 2006, de facto partners represented 15% of all people living as socially married - that is, all those either in a registered marriage or a de facto relationship - up from 12% in 2001 and 10% in 1996. Total de facto partners in 2006 represented 7% of all persons aged 15 years and over, up from 6% in 2001 and 5% in 1996. These rises may be due to both increases in the number of de facto partners and in the willingness of people to identify themselves as living in de facto relationships. In 2006, the median age of males in de facto relationships was 35.3 years while the median age of females was 33.3 years. In 1996, the comparative medians were 34.4 years and 32.0 years respectively. Graph 7.44 shows the age distribution of male and female partners in de facto relationships in 2006. ...

Indicator values are prone to statistical error (the difference between an estimated value and the true value). The statistical error associated with an indicator depends on the population subgroup (e.g. the population of a county or LGD) that it refers to. Such differences in levels of statistical error can distort what we see in maps and charts. They can make some relationships involving indicators and attributes appear "real" (practically meaningful or statistically significant) when they are in fact spurious; other relationships that are "real" can be masked. These differences in statistical error can even distort the shape of plots or the colour patterns we see in maps. For example, ...
The implemented method uses for smoothing bivariate thin plate splines, bivariate lasso-type regularization, and allows for both period and cohort effects. Thus the mortality rates are modelled as the sum of four components: a smooth bivariate function of age and time, smooth one-dimensional cohort effects, smooth one-dimensional period effects and random errors.. ...

Monthly trends in deaths attributed to asthma in the 5-34 year age group were examined for England and Wales over the period 1960-82. Deaths were most frequent in the third quarter (July to September) and peaked in August. Analysis of the 1970-82 period showed that this variation was present in the three constituent age groups 5-14, 15-24, and 25-34 but was most pronounced in the 5-14 year olds. ...

This study demonstrates on a national level that state legislation mandating booster seat use for children aged 4 to 7 years is associated with decreased rates of MVC fatalities, even after controlling for temporal and other legislative factors. In the unadjusted comparison of MVC fatality rates over time in states that enacted booster seat legislation during the study period, decreased rates were noted for children in the 4- to 5-year-old and 6-year-old age groups, but not in the 7-year-old age group. In contrast, in states with no booster seat legislation, there were no statistically significant changes in fatality rates for any age group. After controlling for other motor vehicle legislation as well as temporal and economic factors, states with booster seat laws had decreased MVC fatality rates in all age groups compared with states with no laws, with the greatest change in the 7-year-old age group, which highlights the importance of booster seat legislation, in particular, for this age ...
Mark-recapture techniques were used to investigate population size, age distribution, size distribution and sex ratio in a population of the lacertid lizard Podarcis bocagei in an abandoned gravel pit in northwest Spain. The study was carried out over a 2-year period. Despite relatively high maximum longevity, the population age distribution was characteristic of small, short-lived lizard species (i.e., there was a relatively high proportion of immature individuals). Population size declined over the study period, largely because of a drop in the number of immature animals: this may be partially attributable to density-dependent factors, but was probably due largely to a decline in habitat favourability as a result of colonisation of the study site by vegetation. The sex ratio was significantly female-biased in all cohorts studied, not only among adults but also among juveniles and sub-adults. However, sex ratio at hatching (as investigated by laboratory hatching of clutches laid by captured pregnant

Trostle, Alex [1], Goyal, Anshu [1], Galuska, Sally [1], Reardon, Chris [1], Tiley, George [2], Ellis, Jake [1], Li, Zheng [3], Sutherland, Brittany [4], Barker, Michael [3]. Machine learning approaches for the inference of WGDs from gene age distributions.. The inference of whole genome duplications (WGDs) from gene age distributions or Ks plots is frequently more of an art than exact science. Ancient WGDs leave characteristic peaks of gene duplication in Ks plots that are often relatively easy to identify by eye. However, depending on the data source, Ks estimation method, variation in gene birth and death rates, gene retention rates, and other variables, these peaks may not always appear to be prominent. Most of the statistical approaches applied to this problem often search for a peak of duplication that is statistically significant relative to a null background or fit normal distributions to a range of Ks values. Diagnosing WGDs in these cases can often ...
BACKGROUND: Contemporary population-based data on age-specific incidence and outcome from acute abdominal aortic aneurysm (AAA) events are needed to understand the impact of risk factor modification and demographic change, and to inform AAA screening policy. METHODS: In a prospective population-based study (Oxfordshire, UK, 2002-2014), event rates, incidence, early case fatality and long-term outcome from all acute AAA events were determined, both overall and in relation to the four main risk factors: smoking, hypertension, male sex and age. RESULTS: Over the 12-year interval, 103 incident acute AAA events occurred in the study population of 92,728 (men 72·8 per cent; 59·2 per cent 30-day case fatality rate). The incidence per 100,000 population per year was 55 in men aged 65-74 years, but increased to 112 at age 75-84 years and to 298 at age 85 years or above. Some 66·0 per cent of all events occurred in those aged 75 years or more. The incidence at 65-74 years was highest in male smokers (274 per
Results of the present analyses of the RIDI study provide evidence of 1) large geographical variations in risk of childhood type 1 diabetes within Italy, with high-risk areas in both Sardinia and Trento, in the North-East of Italy; 2) a significantly lower risk in girls than in boys, which is more pronounced in Sardinia (−23%) than in peninsular Italy (−9%); and 3) a linear increasing temporal trend, with an annual increment of 2.94%, affecting all age-groups and both sexes. In our dataset, however, it was impossible to ascribe this increase definitively to either a birth cohort or a calendar period effect.. Our findings are based on a national registry using standardized methods of ascertainment of incident cases, covering 40% of the Italian population at risk; moreover, the long time period on which this report is based allows us to add to current knowledge on epidemiology of type 1 diabetes. Heterogeneity of type 1 diabetes risk has been reported worldwide, but Italy is one of the ...
Objective: To study the change in incidence of hospitalisation for a first acute myocardial infarction (AMI) in the Netherlands from 1995 to 2000. Methods: Patients hospitalised with their first AMI in the Netherlands in 1995 and 2000 were identified through linkage of the national hospital discharge register and the population register. Results: 21 565 ... read more patients hospitalised for their first AMI in 1995 and 19 058 patients hospitalised for their first AMI in 2000 were identified. In both years, the age specific incidence of hospitalisation for a first AMI was higher in men than in women and increased with age (up to 90 years). In both men and women, the age standardised incidence was lower in 2000 than in 1995, a decline of 19% (95% confidence interval 17% to 21%) and 17% (95% confidence interval 14% to 19%), respectively. Conclusions: Our study provides the first nationwide incidence estimates of first AMI in the Netherlands. From 1995 to 2000, the risk of AMI declined ...

Studies of the population of Rochester, Minnesota, have provided the only data on temporal trends for the incidence of stroke in North America. Among the residents of Rochester, the average annual incidence rate of stroke declined by 46%, from 213 to 115 per 100,000 population, between 1950-1954 and 1975-1979. The decline occurred in all age and sex groups, but it occurred earlier in women than in men. The rates stabilized in the 1970s, and did so earlier in women. For 1980-1984, the incidence rate of stroke was 17% higher than that for 1975-1979. The onset of the decline in incidence rates coincided with the introduction of effective antihypertensive therapy, but stabilized and increased rates were associated with continuing improvement in the control of hypertension. The increase in the incidence rates of stroke coincided with the introduction of computed tomography, which appeared to increase the detection of less severe strokes. ...
Background: Secular trends in incidence and prognosis of molecular breast cancer subtypes are poorly described. We studied long-term trends in a population of Norwegian women born 1886-1977.. Methods: A total of 52,949 women were followed for breast cancer incidence, and 1,423 tumors were reclassified into molecular subtypes using IHC and in situ hybridization. We compared incidence rates among women born 1886-1928 and 1929-1977, estimated age-specific incidence rate ratios (IRR), and performed multiple imputations to account for unknown subtype. Prognosis was compared for women diagnosed before 1995 and in 1995 or later, estimating cumulative risk of death and HRs.. Results: Between 50 and 69 years of age, incidence rates of Luminal A and Luminal B (HER2−) were higher among women born in 1929 or later, compared with before 1929 [IRRs 50-54 years; after imputations: 3.5; 95% confidence interval (CI), 1.8-6.9 and 2.5; 95% CI, 1.2-5.2, respectively], with no clear differences for other subtypes. ...
