Stage-specific incidence trends of renal cancers in the East of England, 1999-2016.
Ontology highlight
ABSTRACT: Objectives
To determine stage-specific time-trends in renal cancer incidence.Methods
We used population-based East Anglia data 1999-2016 (population ∼2 million) on 5,456 primary renal cancer diagnoses, estimating stage-specific annual incidence using Poisson regression, allowing for changing time-trends, and adjusting for sex, age, and socioeconomic deprivation.Results
Renal cancer incidence increased from 9.8-16.4 cases per 100,000 during 1999-2016. Incidence of Stage I, II, and III cases increased over time, most steeply for Stage I, with annual Incidence Rate Ratio [IRR] for Stage I of 1.09 (95 % CI 1.07-1.12) during 1999-2010; and 1.03 (1.00-1.05) during 2011-2016. In contrast, the annual incidence of Stage IV renal cancer decreased during most years, IRR of 0.99 (0.98-1.00) during 2003-2016.Conclusion
The findings are consistent with both earlier detection of symptomatic renal cancer and increasing identification of asymptomatic lesions. However, the decreasing incidence of late-stage disease suggests genuine shifts towards earlier diagnosis.

Project description:BackgroundUpdating national trends in diabetes management is important for identifying areas of progress and remaining gaps in diabetes care.ObjectiveEvaluate trends in diabetes management.DesignThree nationally representative, serial cross-sectional surveys (National Health and Nutrition Examination Survey [n = 5800], National Health Interview Survey [n = 48,519], and Behavioral Risk Factor Surveillance System [n = 741,497]) were used to estimate trends in diabetes management from 1999 to 2016.ParticipantsNon-pregnant US adults (aged ≥ 18 years) diagnosed with diabetes.Main measuresAmerican Diabetes Association's general recommendations for glycemic and cardiovascular risk factor control, medication usage, physical activity, preventive practices, and dietary intake.Key resultsFrom 1999 to 2016, the proportion of US adults with diabetes who attained glycemic control (HbA1c < 7.0%) followed a quadratic trend (49.6% in 1999-2004 to 58.6% in 2005-2010 to 55.8% in 2011-2016, P < 0.05 for trend). Control of blood pressure (< 140/90 mmHg) and lipids (LDL cholesterol < 100 mg/dl) increased by 6.6 and 18.7 percentage points, respectively (P < 0.05 for trends). The proportion that attained glycemic, blood pressure, and lipid control followed a quadratic trend (13.3% in 1999-2004 to 24.8% in 2005-2010 to 20.2% in 2011-2016, P < 0.05 for trend). Use of antidiabetic, antihypertensive, and statin medication among those who were eligible rose by 8.6, 5.0, and 24.0 percentage points, respectively (P < 0.05 for trends). Aerobic inactivity declined 7.1 percentage points, while adherence to aerobic activity (≥ 150 min/week) and resistance training (≥ 2 times/week) recommendations grew 3.4 and 3.2 percentage points, respectively (P < 0.05 for trends). Engagement in preventive practices (e.g., receipt of vaccinations) consistently increased for 6 out of 8 outcomes. However, the adherence to saturated fat (< 10% of total daily calories) and sodium (< 2300 mg/day) recommendations fell by 6.5 and 5.2 percentage points (P < 0.05 for trends).ConclusionsDespite notable improvements, declines in glycemic control and adherence to dietary recommendations may be growing challenges in diabetes care.

Project description:OBJECTIVE:Primary peritoneal cancer (PPC), ovarian cancer (OC), and fallopian tube cancer (FTC) are considered as a single disease group. As knowledge of the pathogenesis and clinical presentation of peritoneal, ovarian, and fallopian tube (POFT) cancer grows, the tendencies in OC diagnosis are changing. We investigate the incidence and clinical characteristics of epithelial POFT based on cancer site and histologic type. METHODS:Data from the Korea Central Cancer Registry for the period between 1999 and 2016 were analyzed. The incidence rates and annual percent changes (APCs) for each tumor site were reported. RESULTS:Among 27,768 women with cancer, 1,086 (3.91%) had PPC, 25,847 (93.08%) had OC, and 835 (3.01%) had FTC. Age-standardized rates increased from 0.05 to 0.24, 3.51 to 5.48, and 0.04 to 0.28 in PPC, OC, and FTC, respectively. The proportion of PPC and FTC among all the POFT cases increased consistently during the study period (from, respectively, 1.48 and 1.06 in 1999 to 4.52 and 4.76 in 2016). The APC of PPC, OC, and FTC during 1999-2016 was 9.3%, 2.7%, and 8.6%, respectively. The incidence of PPC, OC, and FTC was highest among patients in the 65-69, 50-54, and 55-59 years age group, respectively. CONCLUSION:The overall incidence of PPC, OC, and FTC cancer has steadily increased. The relative increase of PPC and FTC has been significant. In this study, OC incidence had a relatively young peak age, in contrast to FTC and PPC, which had an older peak age.

Project description:PurposeThis descriptive study was aimed to examine trends in the incidence of melanoma and nonmelanoma in South Korea.Materials and methodsThe nationwide incidence data for melanoma and non-melanoma skin cancer was obtained from the Korea Central Cancer Registry. Age-standardized rates were calculated and analyzed, using a Joinpoint regression model.ResultsThe incidence of basal cell carcinoma has increased dramatically both in men (average annual percentage change [AAPC], 8.0 [95% confidence interval (CI), 6.0 to 10.1]) and women (AAPC, 9.0 [95% CI, 7.5 to 10.4]). Squamous cell carcinoma has also steadily increased both in men (AAPC, 3.3 [95% CI, 2.6 to 4.0]) and women (AAPC, 6.8 [95% CI, 5.3 to 8.4]). Cutaneous melanoma increased continuously from 1999 to 2014 inwomen (AAPC, 3.5 [95% CI, 2.4 to 4.6]), whilst rapidly increasing in men until 2005 (APC, 7.9 [95% CI, 2.4 to 13.7]) after which no increase has been observed (APC, ‒0.2 [95% CI, ‒2.3 to 2.0]).ConclusionThe incidence rates of melanoma and non-melanoma skin cancer have increased over the past years, with the exception of melanoma in men. Further studies are required to investigate the reasons for the increased incidence of these skin cancers in South Korea.

Project description:BackgroundDifferential uptake of prostate-specific antigen testing in the US and UK has been linked to between-country differences for prostate cancer incidence. We examined stage-specific fatal prostate cancer incidence trends in the US and England, by treatment and race/ethnicity.MethodsUsing data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program and Public Health England's National Cancer Registration and Analysis Service, we identified prostate cancer patients diagnosed between 1995 and 2005, aged 45-84 years. Fatal prostate cancer was defined as death attributed to the disease within 10 years of diagnosis. We used age-period-cohort models to assess trends in fatal prostate cancer incidence.ResultsFatal prostate cancer incidence declined in the US by -7.5% each year and increased in England by 7.7% annually. These trends were primarily driven by locoregional disease in the US and distant disease in England. Black men in both countries had twofold to threefold higher fatal prostate cancer incidence rates, when compared with their white counterparts; however, receipt of radical prostatectomy lessened this disparity.ConclusionsWe report a significant increasing rate of fatal prostate cancer incidence among English men. The black-white racial disparity appears pervasive but is attenuated among those who received radical prostatectomy in the US.

Project description:Importance:Prior studies of dietary trends among US youth have evaluated major macronutrients or only a few foods or have used older data. Objective:To characterize trends in diet quality among US youth. Design, Setting, and Participants:Serial cross-sectional investigation using 24-hour dietary recalls from youth aged 2 to 19 years from 9 National Health and Nutrition Examination Survey (NHANES) cycles (1999-2016). Exposures:Calendar year and population sociodemographic characteristics. Main Outcomes and Measures:The primary outcomes were the survey-weighted, energy-adjusted mean consumption of dietary components and proportion meeting targets of the American Heart Association (AHA) 2020 continuous diet score (range, 0-50; based on total fruits and vegetables, whole grains, fish and shellfish, sugar-sweetened beverages, and sodium). Additional outcomes were the AHA secondary score (range, 0-80; adding nuts, seeds, and legumes; processed meat; and saturated fat) and Healthy Eating Index (HEI) 2015 score (range, 0-100). Poor diet was defined as less than 40% adherence (scores, <20 for primary and <32 for secondary AHA scores); intermediate as 40% to 79.9% adherence (scores, 20-39.9 and 32-63.9, respectively); and ideal, as at least 80% adherence (scores, ?40 and ?64, respectively). Higher diet scores indicate better diet quality; a minimal clinically important difference has not been quantified. Results:Of 31?420 youth aged 2 to 19 years included, the mean age was 10.6 years; 49.1% were female. From 1999 to 2016, the estimated AHA primary diet score significantly increased from 14.8 (95% CI, 14.1-15.4) to 18.8 (95% CI, 18.1-19.6) (27.0% improvement), the estimated AHA secondary diet score from 29.2 (95% CI, 28.1-30.4) to 33.0 (95% CI, 32.0-33.9) (13.0% improvement), and the estimated HEI-2015 score from 44.6 (95% CI, 43.5-45.8) to 49.6 (95% CI, 48.5-50.8) (11.2% improvement) (P?<?.001 for trend for each). Based on the AHA primary diet score, the estimated proportion of youth with poor diets significantly declined from 76.8% (95% CI, 72.9%-80.2%) to 56.1% (95% CI, 51.4%-60.7%) and with intermediate diets significantly increased from 23.2% (95% CI, 19.8%-26.9%) to 43.7% (95% CI, 39.1%-48.3%) (P?<?.001 for trend for each). The estimated proportion meeting ideal quality significantly increased but remained low, from 0.07% (95% CI, 0.01%-0.49%) to 0.25% (95% CI, 0.10%-0.62%) (P?=?.03 for trend). Persistent dietary variations were identified across multiple sociodemographic groups. The estimated proportion of youth with a poor diet in 2015-2016 was 39.8% (95% CI, 35.1%-44.5%) for ages 2 to 5 years (unweighted n?=?666), 52.5% (95% CI, 46.4%-58.5%) for ages 6 to 11 years (unweighted n?=?1040), and 66.6% (95% CI, 61.4%-71.4%) for ages 12 to 19 years (unweighted n?=?1195), with persistent differences across levels of parental education, household income, and household food security status. Conclusions and Relevance:Based on serial NHANES surveys from 1999 to 2016, the estimated overall diet quality of US youth showed modest improvement, but more than half of youth still had poor-quality diets.

Project description:ImportanceIt is not yet known how many children and adolescents die each year from opioid poisonings and how mortality rates have changed over time.ObjectiveTo examine national trends in pediatric deaths from prescription and illicit opioids.Design, setting, and participantsCross-sectional in which serial mortality data from the Centers for Disease Control and Prevention were analyzed. The population included 8986 children and adolescents (age, <20 years) who died in all US settings from opioid poisonings between 1999 and 2016. Data were collected and analyzed between June 1 and October 31, 2018.ExposuresAll opioids.Main outcomes and measuresAge-specific mortality rates per 100?000 were estimated with smoothing spline Poisson regression.ResultsOf the 8986 children and adolescents who died between 1999 and 2016 from prescription and illicit opioid poisonings, 6567 (73.1%) were male, 7921 (88.1%) were among adolescents aged 15 to 19 years, and 605 (6.7%) were among children aged 0 to 4 years. The overall pediatric mortality rate increased from 0.22 (95% CI, 0.19-0.25) to 0.81 (95% CI, 0.76-0.88) per 100?000, an increase of 268.2% (P for time effect <.001). The highest annual rates were among adolescents aged 15 to 19 years, but time trends revealed a steady linear increase among children aged 0 to 4 years and those aged 5 to 9 years as well as a steady linear increase until 2008 among the cohorts aged 10 to 14 years and 15 to 19 years, when rates briefly declined before rising again. Among adolescents aged 15 to 19 years, heroin was implicated in 1872 deaths: rates increased from 0.21 (95% CI, 0.17-0.25) to 1.06 (95% CI, 0.97-1.17), an increase of 404.8%, whereas rates for prescription opioids increased by 94.7% from 0.57 (95% CI, 0.49-0.66) to 1.11 (95% CI, 0.99-1.25) (all P for time effect <.001). Between 2014 and 2016, there were 1508 opioid deaths among adolescents aged 15 to 19 years; of these, 468 (31.0%) were attributed to synthetic opioids. Across time, 7263 (80.8%) of all pediatric deaths were unintentional, 5537 (61.6%) occurred outside of a medical facility, and 3419 (38.0%) children died at home or another residential setting. Among children younger than 5 years, 148 (24.5%) deaths were attributed to homicide.Conclusions and relevanceOver 18 years, nearly 9000 children and adolescents died from opioid poisonings, and the mortality rate increased nearly 3-fold. These findings suggest that the opioid epidemic is likely to remain a growing public health problem in the young unless legislators, public health officials, clinicians, and parents take a wider view of the opioid crisis and implement protective measures that are pediatric specific and family centered.

Project description:Objective: No assessment was conducted describing the age and gender specific epidemiology of lung cancer (LC) prior to 2018 in Hungary, thus the objective of this study was to appraise the detailed epidemiology of lung cancer (ICD-10 C34) in Hungary based on a retrospective analysis of the National Health Insurance Fund database. Methods: This longitudinal study included patients aged ≥20 years with LC diagnosis (ICD-10 C34) between January 1, 2011 and December 31, 2016. Patients with different cancer-related codes 6 months before or 12 months after LC diagnosis or having any cancer treatment other than lung cancer protocols were excluded. Results: Lung cancer incidence and mortality increased with age, peaking in the 70-79 age group (375.0/100,000 person-years) among males, while at 60-69 age group for females (148.1/100,000 person-years). The male-to-female incidence rate ratio reached 2.46-3.01 (p < 0.0001) among the 70-79 age group. We found 2-11% decrease in male incidence rate at most age groups, while a significant 1-3% increase was observed in older females (>60) annually during the study period. Conclusion: This nationwide epidemiology study demonstrated that LC incidence and mortality in Hungary decreased in younger male and female population, however we found significant increase of incidence in older female population, similar to international trends. Incidence rates peaked in younger age-groups compared to Western countries, most likely due to higher smoking prevalence in these cohorts, while lower age LC incidence could be attributed to higher competing cardiovascular risk resulting in earlier mortality in smoking population.

Project description:Dental implants have become an increasingly popular treatment choice for replacing missing teeth. Yet, little is known about the prevalence and sociodemographic distribution of dental implant use in the United States. To address this knowledge gap, we analyzed data from 7 National Health and Nutrition Examination Surveys from 1999 to 2016. We estimated dental implant prevalence among adults missing any teeth for each survey period overall as stratified by sociodemographic characteristics. We calculated absolute and relative differences from 1999-2000 to 2015-2016 and fit logistic regression models to estimate changes over time. We also used multivariable logistic regression to estimate independent associations of sociodemographic covariates with the presence of any implant. We projected the proportion of patients treated with dental implants into the year 2026 under varying assumptions of how the temporal trend would continue. There has been a large increase in the prevalence of dental implants, from 0.7% in 1999 to 2000 to 5.7% in 2015 to 2016. The largest absolute increase in prevalence (12.9%) was among individuals 65 to 74 y old, whereas the largest relative increase was ~1,000% among those 55 to 64 y old. There was an average covariate-adjusted increase in dental implant prevalence of 14% per year (95% CI, 11% to 18%). Having private insurance (vs. none or public insurance) or more than a high school education (vs. high school or less) was each associated with a 2-fold increase in prevalence, with an almost 13-fold (95% CI, 8 to21) increase for older adults. Dental implant prevalence projected to 2026 ranged from 5.7% in the most conservative scenario to 23% in the least. This study demonstrates that dental implant prevalence among US adults with missing teeth has substantially increased since 1999. Yet access overall is still very low, and prevalence was consistently higher among more advantaged groups.

Project description:BACKGROUND:Recent reports have noted increasing rates of anal cancer among high-income countries worldwide; however, little is known about these trends in Austria. METHODS:Data on anal cancer from 1983 to 2016 were obtained from Statistics Austria. All tumors (n?=?3567) were classified into anal squamous cell carcinomas (ASCC), anal adenocarcinomas (AADC), and others (unspecified carcinoma and other specific carcinoma). Anal cancer incidence rates were calculated in 5?year cycles and incidence average annual percentage change (AAPC) to evaluate trends by sex, histology and age group. RESULTS:The incidence rate of anal cancer was higher among females than males (relative risk, RR?=?1.66, 95% confidence interval, CI: 1.55-1.79, p?<?0.0001). From 1983 through 2016, incident anal cancer increased significantly (0.92 per 100,000 person-years to 1.85 per 100,000 person-years, AAPC?=?1.93, 95% CI: 1.52 to 2.34, p?<?0.0001), particularly among those 40-69 years old. From 1983 through 2016, the increasing anal cancer incidence was primarily driven by ASCC (0.47-1.20 per 100,000 person-years, AAPC?=?2.23, 95% CI: 1.58 to 2.88, p?<?0.0001) and others (other than ASCC and AADC, AAPC?=?1.78, 95% CI: 1.01-2.55), yet stable in AADC (AAPC?=?0.88, 95% CI: -0.48-2.25). CONCLUSIONS:Despite being a rare cancer in Austria, the increase in anal cancer incidence rate from 1983 to 2016 was substantial, particularly in ASCC. The observed rising trends reflect the need to investigate associated risk factors that have increased over time to inform preventive measures.
