A Qualitative Study of Patients' Lived Experiences of Free Tissue Transfer for Diabetic Foot Disease.

Background: Free tissue transfer (FTT) for reconstruction of diabetic foot disease (DFD) is an emerging field to preserve the lower limb within this patient group. The design of future quantitative research and clinical services in this area must consider the needs, expectations and concerns of patients. This qualitative study explores patient experiences of FTT for reconstruction of DFD. Methods: Semistructured interviews were conducted to explore patients' lived experiences of FTT for DFD. A purposive sampling strategy identified six patients who underwent FTT for recalcitrant DFD between September 2019 and December 2021 in a single center in the United Kingdom. Results: Three experiential themes emerged. Theme 1: "negative lived experiences of living with DFD" included frustration with the chronic management of nonhealing ulcers and fear regarding limb amputation. Theme 2: "surgery related concerns" included fears of reconstructive failure and subsequent amputation, as well as foot cosmesis and donor-site morbidity. Theme 3: "positive lived experiences following reconstruction" included the positive impact the reconstruction had on their overall life and diabetic control. All patients would repeat the process to obtain their current results. Conclusions: This qualitative study provides first-hand insight into the lived experience of FTT for DFD, exploring both the negative and positive experiences and reasons for these. We found that FTT for DFD can be positively life-changing for affected individuals.

Structural validation of the Manchester-Oxford Foot Questionnaire for use in foot and ankle surgery.

Aims: The Manchester-Oxford Foot Questionnaire (MOxFQ) is an anatomically specific patient-reported outcome measure (PROM) currently used to assess a wide variety of foot and ankle pathology. It consists of 16 items across three subscales measuring distinct but related traits: walking/standing ability, pain, and social interaction. It is the most used foot and ankle PROM in the UK. Initial MOxFQ validation involved analysis of 100 individuals undergoing hallux valgus surgery. This project aimed to establish whether an individual's response to the MOxFQ varies with anatomical region of disease (measurement invariance), and to explore structural validity of the factor structure (subscale items) of the MOxFQ. Methods: This was a single-centre, prospective cohort study involving 6,637 patients (mean age 52 years (SD 17.79)) presenting with a wide range of foot and ankle pathologies between January 2013 and December 2021. To assess whether the MOxFQ responses vary by anatomical region of foot and ankle disease, we performed multigroup confirmatory factor analysis. To assess the structural validity of the subscale items, exploratory and confirmatory factor analyses were performed. Results: Measurement invariance by pathology was confirmed, suggesting the same model can be used across all foot and ankle anatomical regions. Exploratory factor analysis demonstrated a two- to three-factor model, and suggested that item 13 (inability to carry out work/everyday activities) and item 14 (inability to undertake social/recreational activities) loaded more positively onto the "walking/standing" subscale than their original "social interaction" subscale. Conclusion: This large cohort study supports the current widespread use of the MOxFQ across a broad range of foot and ankle pathologies. Our analyses found indications that could support alterations to the original factor structure (items 13 and 14 might be moved from the "social interaction" to the "walking/standing" subscale). However, this requires further work to confirm.

Trends in the incidence of rib and sternal fractures: A nationwide study of the global burden of disease database, 1990-2019.

INTRODUCTION: Fractures of the ribs and sternum are associated with significant morbidity and mortality. Characterization of the injury burden across England is necessary to inform and evaluate developments in trauma care and infrastructure, however is yet to be comprehensively undertaken. Therefore, the aim of this study was to describe trends in the incidence of sternal and rib fractures across England between 1990 and 2019. MATERIALS AND METHODS: Age-standardised incidence rates (ASIRs) for rib and sternal fractures in males and females were extracted from the 2019 Global Burden of Disease (GBD) study by all causes, falls and road traffic collisions for 9 sub-regions of England. Temporal trends within the study period were analysed using Joinpoint regression analysis. RESULTS: The overall ASIRs in England in 2019 were 30.34/100,000 and 46.02/100,000 for females and males, respectively. Between 1990 and 2019, the estimated overall percentage change across England was +0.20 % among females and -7.05 % among males. A statistically significant increase in ASIR was observed in all 9 sub-regions of England among females from 2014-2019 (p<0.001). Among males, a statistically significant increase in ASIR was observed in 7 of the 9 regions from 2014-2019 (p<0.001) and in the remaining 2 regions from 2015-2019 (p<0.001). DISCUSSION: Increasing ASIRs of rib and sternal fractures were observed among females and decreasing ASIRs among males, with overall ASIRs higher among males. Developments in trauma infrastructure and associated variations in diagnostic and management strategies over the observation period likely contribute to changes in the national injury burden. The findings are suggestive of the importance of ongoing financial investment in trauma infrastructure and of clear clinical guidelines to manage an increasing national injury burden.

Type 1 diabetes mellitus disease burden in high health expenditure countries between 1990 and 2019.

OBJECTIVE: This observational study assesses trends in type 1 diabetes mellitus (T1DM) disease burden across the 19 countries of the European Union (EU) 15+ between 1990 and 2019. METHODS: The Global Burden of Disease Study database was used to gather T1DM age-standardised incidence (ASIR), prevalence (ASPR), mortality (ASMR), and disability-adjusted life-year (DALY) rates per 100,000 for each EU15+ country (1990 - 2019). Joinpoint regression analysis was used to describe the trends. RESULTS: From 1990 to 2019, T1DM ASIRs and ASPRs increased globally except for females in Finland (-2.9% and -9.4%), the largest increase in ASPR for males and females was observed in France (+144.4% and +137.5% respectively). All had reductions in ASMRs for males and females, with the largest observed in Spain (-56.7% and -79.0% respectively). Trends in DALYs were variable across countries, with increases in DALYs noted in 14/19 for males, and 9/19 for females. Denmark, Finland, Norway, Netherlands, and Sweden had a reduction in DALYs for both males and females. CONCLUSIONS: Mortality from T1DM is reducing across EU15+ countries, despite concomitant increases in incidence and prevalence rates. Trends in DALYs are variable across countries, reflecting differential trends in the disease burden across countries with similarly high health expenditure.

Trends in the mortality, incidence and disability-adjusted life-years of appendicitis in EU15+ countries: an observational study of the Global Burden of Disease Database, 1990-2019.

BACKGROUND: Appendicitis places a substantial burden on healthcare systems, with acute appendicitis alone being the most common abdominal surgical emergency worldwide. Further characterisation of the disease burden in EU15+ countries may help optimise the distribution of healthcare resources. The aim of this observational study was to assess the trends in mortality, incidence and disability-adjusted life-years (DALYs) of appendicitis across European Union (EU) 15+ countries between the years 1990 and 2019, Supplemental Digital Content 3, http://links.lww.com/JS9/A589 . MATERIALS AND METHODS: Age-standardised mortality rates (ASMRs), age-standardised incidence rates (ASIRs) and DALYs data for appendicitis in males and females were extracted from the 2019 Global Burden of Disease (GBD) study. Temporal trends within the study period were analysed using Joinpoint regression analysis. RESULTS: The median ASMRs across EU15+ countries in 2019 were 0.08/100 000 and 0.13/100 000 for females and males, respectively. Between 1990 and 2019 the median percentage change in ASMR was -52.12% for females and -53.18% in males. The median ASIRs in 2019 for females and males were 251/100 000 and 278/100 000, respectively, with a median percentage change of +7.22% for females and +3.78% for males during the observation period. Decreasing trends in DALYs were observed over the 30-year study period, with median percentage changes of -23.57% and -33.81% for females and males, respectively, Supplemental Digital Content 3, http://links.lww.com/JS9/A589 . CONCLUSION: Overall, a general trend of decreasing appendicitis ASMRs and DALYs was observed across EU15+ countries, despite small overall increases in appendicitis ASIRs, Supplemental Digital Content 3, http://links.lww.com/JS9/A589 . Variations in both diagnostic and management strategies over the study period are likely contributory to the changing trends.

Trends in keratinocyte skin cancer incidence, mortality and burden of disease in 33 countries between 1990 and 2017.

BACKGROUND: Keratinocyte cancers (KCs) are the most common type of cancer in the White population worldwide, with associated high healthcare costs. Understanding the epidemiological trends for KCs, namely basal cell carcinomas (BCCs) and cutaneous squamous cell carcinomas (SCCs), is required to assess burden of disease, project future trends and identify strategies for addressing this pressing global health issue. OBJECTIVES: To report trends in BCC and SCC incidence, and SCC mortality and disability-adjusted life-years (DALYs). METHODS: An observational study of the Global Burden of Disease (GBD) database between 1990 and 2017 was performed. European Union countries and other selected high-income countries, including the UK and the USA, classified as having high-quality mortality data, were included. Annual age-standardized incidence rates (ASIRs), age-standardized death rates (ASDRs) and DALYs for each country were obtained from the GBD database. Trends were described using joinpoint regression analysis. RESULTS: Overall, 33 countries were included. For both BCC and SCC in 2015-2017, the highest ASIRs were observed in the USA and Australia. Males had higher ASIRs than females at the end of the observation period in all countries for SCC, and in all countries but two for BCC. In contrast, the highest ASDRs for SCC were observed in Australia and Latvia for males, and in Romania and Croatia for females. The highest DALYs for SCC for both sexes were seen in Australia and Romania. Over the observation period, there were more countries demonstrating decreasing trends in mortality than in incidence, and disparities were observed between which countries had comparatively high mortality rates and which had high incidence rates. Overall reductions in SCC DALYs were observed in 24 of 33 countries for males, and 25 countries for females. CONCLUSIONS: Over the past 27 years, although trends in SCC incidence have risen in most countries, there is evidence that mortality rates have been decreasing. Burden of disease as assessed using DALYs has decreased in the majority of countries. Future work will explore potential explanatory factors for the observed disparity in trends in SCC incidence and mortality.

Trends in neck of femur fracture incidence in EU15+ Countries from 1990-2017.

BACKGROUND: Neck of femur fractures (NOFF) pose significant socio-economic costs to society with a high degree of morbidity and mortality. Its incidence rate has been collated within the Global Burden of Disease (GBD) database; however, to date, no comparison across countries has been reported. METHODS: NOFF age-standardised incidence rates (ASIR) per 100,000 population were extracted from the GBD database for European Union (EU) 15+ countries over the period 1990 to 2017. Joinpoint regression analysis of the data identified trends in ASIR and associated estimated annual percentage changes (EAPC). These were analysed by specified timeframe, country and gender. RESULTS: Of the 19 EU15+ countries, 11 (58%) had overall increases in NOFF ASIRs in 2017 compared to 1990. The median ASIRs were 240/100,000 and 322/100,000 for males and females, respectively, in 1990. By 2017, this had increased to 259/100,000 and 325/100,000, respectively. Females consistently had relatively higher NOFF ASIRs with a median gender fracture gap of 62/100,000 in 2017. Males had a higher percentage change in increasing ASIRs, with a smaller percentage change in decreasing ASIRs for all included countries. The highest national ASIRs was observed in Australia, followed by Finland and Belgium. Conversely the Mediterranean countries demonstrated the lowest ASIRs, closely followed by the USA. CONCLUSION: Despite significant advances in primary and secondary hip fracture prevention strategies over the 28-year study period, significant increases in NOFF ASIRs among most EU15+ countries were observed, especially with respect to gender.

Temporal trend analysis of rheumatic heart disease burden in high-income countries between 1990 and 2019.

AIMS: To assesses trends in rheumatic heart disease (RHD) burden in high-income, European Union 15+ (EU15+) countries between 1990 and 2019. METHODS AND RESULTS: Cross-sectional analysis of the incidence and mortality of RHD was conducted using data from the Global Burden of Disease Study (GBD) database. Age-standardized incidence rates (ASIRs) and age-standardized mortality rates (ASMRs) were extracted for EU15 + countries per sex for each of the years from 1990-2019, inclusive, and mortality-to-incidence indices (MII) were computed. Joinpoint regression analysis was used for the description of trends. Over 29 years, an overall declining trend in RHD incidence and mortality across EU 15 + nations were observed. There was significant variability in RHD incidence and mortality rates across high-income countries. However, both RHD incidence and mortality were higher among females compared to males across EU15 + countries over the observed period. The most recent incidence trend, starting predominantly after 2014, demonstrated a rise in RHD incidence in most countries for both sexes. The timing of this RHD resurgence corresponds temporally with an influx of migrants and refugees into Europe. The recent increasing RHD incidence rates ranged from + 0.4% to + 24.7% for males, and + 0.6% to + 11.4% for females. CONCLUSIONS: More than half of EU15 + nations display a recent increase in RHD incidence rate across both sexes. Possible factors associated with this rise are discussed and include increase in global migration from nations with higher RHD prevalence, host nation factors such as migrants' housing conditions, healthcare access and migrant health status on arrival.

Trends in prevalence, mortality, and disability-adjusted life-years relating to chronic obstructive pulmonary disease in Europe: an observational study of the global burden of disease database, 2001-2019.

INTRODUCTION: Chronic Obstructive Pulmonary Disease (COPD) is associated with significant mortality and well-defined aetiological factors. Previous reports indicate that mortality from COPD is falling worldwide. This study aims to assess the burden of COPD using prevalence, mortality, and disability-adjusted life years (DALYs) between 2001 and 2019 in 28 European countries (the European Union and the United Kingdom). METHODS: We extracted COPD data from the Global Burden of Disease database based on the International Classification of Diseases versions 10 (J41, 42, 43, 44 and 47). Age-standardised prevalence rates (ASPRs), age-standardised mortality rates (ASMRs), and DALYs were analysed for European countries by sex for each year (2001-2019) and reported per 100,000 population. We used Joinpoint regression analysis to quantify changing trends in the burden of COPD. RESULTS: In 2019, the median ASPR across Europe was 3230/100,000 for males and 2202/100,000 for females. Between 2001 and 2019, the median percentage change in ASPR was - 9.7% for males and 4.3% for females. 23/28 countries demonstrated a decrease in ASPRs in males, and 11/28 demonstrated a decrease in females. The median percentage change in ASMR between 2001 and 2019 was - 27.5% for males and - 10.4% for females. 25/28 and 19/28 countries demonstrated a decrease in ASMR in males and females, respectively. CONCLUSION: In the EU between 2001 and 2019 COPD prevalence has overall increased in females but continues to decrease in males and in some countries, female prevalence now exceeds that of males. COPD mortality in the EU has decreased overall between 2001 and 2019; however, this decrease is not universal, particularly in females, and therefore remains a substantial source of amenable mortality.

Interstitial lung disease incidence and mortality in the UK and the European Union: an observational study, 2001-2017.

Objective: To compare the trends in age-standardised incidence and mortality from interstitial lung diseases (ILD) in the UK and the European Union (EU). Methods: This was an observational study using data obtained from the Global Burden of Disease Study on residents of the UK and of the 27 EU countries. The main outcome measures were ILD age-standardised incidence rates per 100 000 (ASIR), age-standardised death rates per 100 000 (ASDR) and mortality-to-incidence ratios (MIRs), which are presented for men and women separately for each country for the years 2001-2017. Trends were analysed using joinpoint regression analysis. Results: In 2017, the median incidence of ILD was 7.22 (IQR 5.57-8.96) per 100 000 population for men and 4.34 (IQR 3.36-6.29) per 100 000 population for women. In 2017, the median ASDR attributed to ILD was 2.04 (IQR 1.13-2.71) per 100 000 population for men and 1.02 (0.68-1.37) per 100 000 population for women. There was an overall increase in ASDR during the observation period, with a median increase of +20.42% (IQR 5.44-31.40) for men and +15.44% (IQR -1.01-31.52) for women. Despite increases in mortality over the entire observation period, there were decreasing mortality trends in the majority of countries at the end of the observation period (75% for men and 86% for women). Conclusion: Over the past two decades, there have been increases in the incidence and mortality of ILD in Europe. The most recent trends, however, demonstrate decreases in mortality from ILD in the majority of European countries for both men and women. These data support the ongoing improvements in the diagnosis and management of ILD.

A Comparison of the Burden of Thyroid Cancer Among the European Union 15+ Countries, 1990-2019: Estimates From the Global Burden of Disease Study.

Importance: The global incidence of thyroid cancer has been increasing rapidly, and this increase has had an attendant burden on health systems. However, it is unclear how the burden of this disease differs among the pre-2004 countries of the European Union (Austria, Belgium, Denmark, Finland, France, Germany, Greece, Ireland, Italy, Luxembourg, Netherlands, Portugal, Spain, Sweden, and the UK), US, Australia, Canada, and Norway (EU15+). Objective: To assess the trends in mortality, incidence, and disability-adjusted life-years (DALYs) associated with thyroid cancer between 1990 and 2019 in EU15+ nations. Data analysis was conducted from July 11 to October 11, 2021. Design, Setting, and Participants: Observational cross-sectional analysis of the incidence of thyroid cancer was conducted using data obtained from the Global Burden of Disease Study database. Nineteen countries of the EU15+ were included. Exposures: Thyroid cancer. Main Outcomes and Measures: Age-standardized incidence rates (ASIRs), age-standardized mortality rates (ASMRs) and DALYs were extracted for individual EU15+ countries per sex for each of the years from 1990 to 2019, and mortality-to-incidence indexes were computed. Joinpoint regression analysis was used to describe the trends. Results: Thirteen of 19 countries (68%) showed an average annual percentage change increase in ASIR across the study period (range, 0.2%-2.5%). Joinpoint regression analysis revealed largely plateauing ASIR trends in recent years across most EU15+ nations since 1990. Between 2011 and 2019, the estimated annual percentage change in the US was 0. Australia, Denmark, and the US were the only countries with increasing ASMR trends with positive average annual percentage changes: Australia, 0.6 (95% CI, 0.2-1.0); Denmark, 1.0 (95% CI, 0.8-1.3); and US, 0.4 (95% CI, 0.4-0.5); the remaining 16 countries showed negative trends (range, -0.2 to -2.1). Disability-adjusted life-years decreased in all EU15+ countries except Australia, Denmark, and the US. Conclusions and Relevance: This cross-sectional analysis found that overall, the burden of thyroid cancer across EU15+ countries appears to be decreasing, evidenced by plateauing incidence rates and reductions in mortality and DALYs over the 30-year study period. However, the US and Australia appear to have increasing ASMR and DALY trends. Ongoing observation is required to monitor how changes in international clinical practice guidelines affect thyroid cancer DALYs and mortality.

An observational epidemiological study to analyze intracerebral hemorrhage across the United States: Incidence and mortality trends from 1990 to 2017.

OBJECTIVES: Intracerebral Hemorrhage (ICH) accounts for 10% of strokes annually in the United States (US). Up-to-date trends in disease burden and regional variations remain unknown. Our study reports updated trends of ICH incidence, mortality, and mortality to incidence ratio (MIR) across the US. MATERIALS AND METHODS: Observational study to evaluate the incidence and mortality from ICH across the US. Data was obtained from Global Burden of Disease (GBD) database. Age-Standardized Incidence (ASIRs) and Death (ASDRs) Rates, as well as the Mortality- to-Incidence ratios (MIRs) for ICH in the US overall and state-wise from 1990-2017. Joinpoint regression analysis was used, with presentation of estimated annual percentage changes (EAPCs). RESULTS: Overall decrease in ASIRs, ASDRs, and MIRs in the US for both sexes. The 2017 mean ASIR was 25.67/100,000 for men and 19.17/100,000 for women, whereas mean ASDR was 13.96/100,000 for men and 11.35/100,000 for women. District of Columbia had greatest decreases in ASIR EAPCs for both men and women at -41.25% and -40.58%, respectively, and greatest decreases in ASDR EAPCs for men and women at -55.38% and -48.51%, respectively. MIR between 1990-2017 decreased in men by -12.12% and women by -7.43%. MIR increased in men from 2014-2017 (EAPC +2.2%) and in women from 2011-2017 (EAPC +1.0%). CONCLUSION: Decreasing trends in incidence, mortality, and MIR. No significant trends in mortality were found in the last 6 years of the study period. MIR worsened in males from 2014-2017 and females from 2011-2017, suggesting decreased ICH-related survival lately.

Trends in Breast Cancer Mortality Between 2001 and 2017: An Observational Study in the European Union and the United Kingdom.

PURPOSE: Breast cancer is the most common cancer in women worldwide, representing 25.4% of the newly diagnosed cases in 2018. The past two decades have seen advancements in screening technologies, guidelines, and newer modalities of treatment. Our study reports and compares trends in breast cancer mortality in the European Union and the United Kingdom. MATERIALS AND METHODS: We used the WHO Mortality Database. We extracted breast cancer mortality data from 2001 to 2017 on the basis of the International Classification of Diseases, 10th revision system. Crude mortality rates were dichotomized by sex and reported by year. We computed age-standardized death rates (ASDRs) per 100,000 population using the world standard population. Breast cancer mortality trends were compared using joinpoint regression analysis. RESULTS: We analyzed data from 24 EU countries, including the United Kingdom. For women, breast cancer mortality was observed to be downtrending in all countries except Croatia, France, and Poland. For the most recent female data, the highest ASDR for breast cancer was identified in Croatia (19.29 per 100,000), and the lowest ASDR was noted in Spain (12.8 per 100,000). Denmark had the highest change in ASDR and the highest estimated annual percentage change of -3.2%. For men, breast cancer mortality decreased in 18 countries, with the largest relative reduction observed in Denmark with an estimated annual percentage change of -27.5%. For the most recent male data, the highest ASDR for breast cancer was identified in Latvia (0.54 per 100,000). CONCLUSION: Breast cancer mortality rates have down trended in most EU countries between 2001 and 2017 for both men and women. Given the observational nature of this study, causality to the observed trends cannot be reliably ascribed. However, possible contributing factors should be considered and subject to further study.

Trends of HIV-Related Cancer Mortality between 2001 and 2018: An Observational Analysis.

The burden of AIDS-defining cancers has remained relatively steady for the past two decades, whilst the burden of non-AIDS-defining cancer has increased. Here, we conduct a study to describe mortality trends attributed to HIV-associated cancers in 31 countries. We extracted HIV-related cancer mortality data from 2001 to 2018 from the World Health Organization Mortality Database. We computed age-standardized death rates (ASDRs) per 100,000 population using the World Standard Population. Data were visualized using Locally Weighted Scatterplot Smoothing (LOWESS). Data for females were available for 25 countries. Overall, there has been a decrease in mortality attributed to HIV-associated cancers among most of the countries. In total, 18 out of 31 countries (58.0%) and 14 out of 25 countries (56.0%) showed decreases in male and female mortality, respectively. An increasing mortality trend was observed in many developing countries, such as Malaysia and Thailand, and some developed countries, such as the United Kingdom. Malaysia had the greatest increase in male mortality (+495.0%), and Canada had the greatest decrease (-88.5%). Thailand had the greatest increase in female mortality (+540.0%), and Germany had the greatest decrease (-86.0%). At the endpoint year, South Africa had the highest ASDRs for both males (16.8/100,000) and females (19.2/100,000). The lowest was in Japan for males (0.07/100,000) and Egypt for females (0.028/100,000).

Trends of HIV Mortality between 2001 and 2018: An Observational Analysis.

Since the beginning of the epidemic in the early 1980s, HIV-related illnesses have led to the deaths of over 32.7 million individuals. The objective of this study was to describe current mortality rates for HIV through an observational analysis of HIV mortality data from 2001 to 2018 from the World Health Organization (WHO) Mortality Database. We computed age-standardized death rates (ASDRs) per 100,000 people using the World Standard Population. We plotted trends using locally weighted scatterplot smoothing (LOWESS). Data for females were available for 42 countries. In total, 31/48 (64.60%) and 25/42 (59.52%) countries showed decreases in mortality in males and females, respectively. South Africa had the highest ASDRs for both males (467.7/100,000) and females (391.1/100,000). The lowest mortalities were noted in Egypt for males (0.2/100,000) and in Japan for females (0.01/100,000). Kyrgyzstan had the greatest increase in mortality for males (+6998.6%). Estonia had the greatest increase in mortality for females (+5877.56%). The disparity between Egypt (the lowest) and South Africa (the highest) was 3042-fold for males. Between Japan and South Africa, the disparity was 43,454-fold for females. Although there was a decrease in mortality attributed to HIV among most of the countries studied, a rising trend remained in a number of developing countries.

Trends in peripheral arterial disease incidence and mortality in EU15+ countries 1990-2017.

AIMS: The aim was to assess trends in peripheral arterial disease (PAD) incidence and mortality rates in European Union(15+) countries between 1990 and 2017. METHODS AND RESULTS: This observational study used data obtained from the 2017 Global Burden of Disease study. Age-standardised mortality and incidence rates from PAD were extracted from the Global Health Data Exchange for EU15+ countries for the years 1990-2017. Trends were analysed using Joinpoint regression analysis.Between 1990 and 2017, the incidence of PAD decreased in all 19 EU15+ countries for females, and in 18 of 19 countries for males. Increasing PAD incidence was observed only for males in the United States (+1.4%). In 2017, the highest incidence rates were observed in Denmark and the United States for males (213.6 and 202.3 per 100,000, respectively) and in the United States and Canada for females (194.8 and 171.1 per 100,000, respectively). There was a concomitant overall trend for increasing age-standardised mortality rates in all EU15+ countries for females, and in 16 of 19 EU15+ countries for males between 1990 and 2017. Italy (-25.1%), Portugal (-1.9%) and Sweden (-0.6%) were the only countries with reducing PAD mortality rates in males. The largest increases in mortality rates were observed in the United Kingdom (males +140.4%, females +158.0%) and the United States (males +125.7%, females +131.2%). CONCLUSIONS: We identify shifting burden of PAD in EU15+ countries, with increasing mortality rates despite reducing incidence. Strong evidence supports goal-directed medical therapy in reducing PAD mortality - population-wide strategies to improve compliance to optimal goal-directed medical therapy are warranted.

Trends in type 2 diabetes mellitus disease burden in European Union countries between 1990 and 2019.

This observational study aimed to assess trends in type 2 diabetes mellitus (T2DM) disease burden in European Union countries for the years 1990-2019. Sex specific T2DM age-standardised prevalence (ASPRs), mortality (ASMRs) and disability-adjusted life-year rates (DALYs) per 100,000 population were extracted from the Global Burden of Disease (GBD) Study online results tool for each EU country (inclusive of the United Kingdom), for the years 1990-2019. Trends were analysed using Joinpoint regression analysis. Between 1990 and 2019, increases in T2DM ASPRs were observed for all EU countries. The highest relative increases in ASPRs were observed in Luxembourg (males + 269.1%, females + 219.2%), Ireland (males + 191.9%, females + 165.7%) and the UK (males + 128.6%, females + 114.6%). Mortality trends were less uniform across EU countries, however a general trend towards reducing T2DM mortality was observed, with ASMRs decreasing over the 30-year period studied in 16/28 countries for males and in 24/28 countries for females. The UK observed the highest relative decrease in ASMRs for males (- 46.9%). For females, the largest relative decrease in ASMRs was in Cyprus (- 67.6%). DALYs increased in 25/28 countries for males and in 17/28 countries for females between 1990 and 2019. DALYs were higher in males than females in all EU countries in 2019. T2DM prevalence rates have increased across EU countries over the last 30 years. Mortality from T2DM has generally decreased in EU countries, however trends were more variable than those observed for prevalence. Primary prevention strategies should continue to be a focus for preventing T2DM in at risk groups in EU countries.

Sentinel node biopsy for diagnosis of lymph node involvement in endometrial cancer.

BACKGROUND: Pelvic lymphadenectomy provides prognostic information for those diagnosed with endometrial (womb) cancer and provides information that may influence decisions regarding adjuvant treatment. However, studies have not shown a therapeutic benefit, and lymphadenectomy causes significant morbidity. The technique of sentinel lymph node biopsy (SLNB), allows the first draining node from a cancer to be identified and examined histologically for involvement with cancer cells. SLNB is commonly used in other cancers, including breast and vulval cancer. Different tracers, including colloid labelled with radioactive technetium-99, blue dyes, e.g. patent or methylene blue, and near infra-red fluorescent dyes, e.g. indocyanine green (ICG), have been used singly or in combination for detection of sentinel lymph nodes (SLN). OBJECTIVES: To assess the diagnostic accuracy of sentinel lymph node biopsy (SLNB) in the identification of pelvic lymph node involvement in women with endometrial cancer, presumed to be at an early stage prior to surgery, including consideration of the detection rate. SEARCH METHODS: We searched MEDLINE (1946 to July 2019), Embase (1974 to July 2019) and the relevant Cochrane trial registers. SELECTION CRITERIA: We included studies that evaluated the diagnostic accuracy of tracers for SLN assessment (involving the identification of a SLN plus histological examination) against a reference standard of histological examination of removed pelvic +/- para-aortic lymph nodes following systematic pelvic +/- para-aortic lymphadenectomy (PLND/PPALND) in women with endometrial cancer, where there were sufficient data for the construction of two-by-two tables. DATA COLLECTION AND ANALYSIS: Two review authors (a combination of HN, JM, NW, RG, and WH) independently screened titles and abstracts for relevance, classified studies for inclusion/exclusion and extracted data. We assessed the methodological quality of studies using the QUADAS-2 tool. We calculated the detection rate as the arithmetic mean of the total number of SLNs detected out of the total number of women included in the included studies with the woman as the unit of analysis, used univariate meta-analytical methods to estimate pooled sensitivity estimates, and summarised the results using GRADE. MAIN RESULTS: The search revealed 6259 unique records after removal of duplicates. After screening 232 studies in full text, we found 73 potentially includable records (for 52 studies), although we were only able to extract 2x2 table data for 33 studies, including 2237 women (46 records) for inclusion in the review, despite writing to trial authors for additional information. We found 11 studies that analysed results for blue dye alone, four studies for technetium-99m alone, 12 studies that used a combination of blue dye and technetium-99m, nine studies that used indocyanine green (ICG) and near infra-red immunofluorescence, and one study that used a combination of ICG and technetium-99m. Overall, the methodological reporting in most of the studies was poor, which resulted in a very large proportion of 'unclear risk of bias' ratings. Overall, the mean SLN detection rate was 86.9% (95% CI 82.9% to 90.8%; 2237 women; 33 studies; moderate-certainty evidence). In studies that reported bilateral detection the mean rate was 65.4% (95% CI 57.8% to 73.0%) . When considered according to which tracer was used, the SLN detection rate ranged from 77.8% (95% CI 70.0% to 85.6%) for blue dye alone (559 women; 11 studies; low-certainty evidence) to 100% for ICG and technetium-99m (32 women; 1 study; very low-certainty evidence). The rates of positive lymph nodes ranged from 5.2% to 34.4% with a mean of 20.1% (95% CI 17.7% to 22.3%). The pooled sensitivity of SLNB was 91.8% (95% CI 86.5% to 95.1%; total 2237 women, of whom 409 had SLN involvement; moderate-certainty evidence). The sensitivity for of SLNB for the different tracers were: blue dye alone 95.2% (95% CI 77.2% to 99.2%; 559 women; 11 studies; low-certainty evidence); Technetium-99m alone 90.5% (95% CI 67.7% to 97.7%; 257 women; 4 studies; low-certainty evidence); technetium-99m and blue dye 91.9% (95% CI 74.4% to 97.8%; 548 women; 12 studies; low-certainty evidence); ICG alone 92.5% (95% CI 81.8% to 97.1%; 953 women; 9 studies; moderate-certainty evidence); ICG and blue dye 90.5% (95% CI 63.2.6% to 98.1%; 215 women; 2 studies; low-certainty evidence); and ICG and technetium-99m 100% (95% CI 63% to 100%; 32 women; 1 study; very low-certainty evidence). Meta-regression analyses found that the sensitivities did not differ between the different tracers used, between studies with a majority of women with FIGO stage 1A versus 1B or above; between studies assessing the pelvic lymph node basin alone versus the pelvic and para-aortic lymph node basin; or between studies that used subserosal alone versus subserosal and cervical injection. It should be noted that a false-positive result cannot occur, as the histological examination of the SLN is unchanged by the results from any additional nodes removed at systematic lymphadenectomy. AUTHORS' CONCLUSIONS: The diagnostic test accuracy for SLNB using either ICG alone or a combination of a dye (blue or ICG) and technetium-99m is probably good, with high sensitivity, where a SLN could be detected. Detection rates with ICG or a combination of dye (ICG or blue) and technetium-99m may be higher. The value of a SLNB approach in a treatment pathway, over adjuvant treatment decisions based on uterine factors and molecular profiling, requires examination in a high-quality intervention study.
