Social needs screening in primary care: A tool in the fight for health equity? PUBLIC HEALTH IN PRACTICE 2024; 7:100466. [PMID: 38323126 PMCID: PMC10844637 DOI: 10.1016/j.puhip.2024.100466] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2023] [Revised: 01/09/2024] [Accepted: 01/16/2024] [Indexed: 02/08/2024] Open
Abstract
Progress on addressing health inequalities is slow and in many places around the world the gap between the privileged and the disadvantaged is widening. This is driven largely by an unfair and unequal distribution of the social determinants of health. While upstream policy and agenda commitment is needed to improve social determinants of health at a population level, healthcare also has a role. Currently social information is sporadically collected and used in healthcare. Improving our understanding of social problems is crucial in targeting services and to reduce the overreliance on area-level measures of deprivation. This has the potential to improve patient care as well as more accurately capture socio-economic disadvantage. Here we argue that there is a role for primary care in screening for social needs to help address inequalities. Social needs screening, more commonly used in North America than Europe, aims to systematically collect social information in health and care settings. Healthcare professionals ask patients about social issues including employment, finances, housing, education and social isolation and this information is used to prompt referral to community services to address any need identified. Social needs screening has potential to address negative impacts of social determinants of health at an individual and population level. Providing a reliable measure of social need, screening gives healthcare professionals an opportunity to tailor and improve quality of care for patients and offer individualised support. It has been shown to improve individual social and health outcomes and positively impact healthcare utilisation. At a population level, social needs screening can improve the data on social determinants of health and therefore support policy makers and service delivery leaders to target resources and services more effectively to the communities most in need. Implementing social needs screening must take account of local healthcare service capacity and available community resources but where sustainable, effective programmes can be introduced, the potential benefits are manifold. While primary care alone cannot solve the root causes of health inequalities, we argue it could be a powerful actor in the fight for health equity.

Abstract
OBJECTIVE Radiological imaging is pivotal in diagnosing idiopathic normal pressure hydrocephalus (iNPH), given the similarity of its symptoms to other neurodegenerative diseases. We aimed to correlate the Evans index (EI), callosal angle (CA), and the volume of the lateral ventricles measured before cerebrospinal fluid removal with the resultant outcomes in gait response. METHODS In our retrospective study, we identified 42 patients with a diagnosis of iNPH. These patients underwent gait analysis, imaging, and lumbar puncture. Radiological assessments included measurements of CA EI and lateral ventricular volume. Clinically, we assessed the following 4 gait parameters: cadence, gait speed, stride length, and timed up and go. Change in the 4 gait parameters was calculated, normalized, and compiled into a composite score, following which the group was divided into 'responders' and 'nonresponders' based on z score of 0.5. Our dependent variable was clinical improvement in gait, and our independent variables included lateral ventricular volume, EI, and CA. We performed a Wilcoxon rank-sum test to compare significant responder status using CA, EI, and lateral ventricle volume. A receiver operating characteristic analysis was employed to determine which volume measurement exhibited the strongest correlation with responder status. Determining the significant variables, a chi-square analysis was subsequently conducted.A significance threshold was set at P < 0.05. All our statistical evaluations were conducted in the Spyder environment, which is compatible with Python 3.10. RESULTS There was a significant difference for responder status in EI and lateral ventricle volume. Evan index showing a statistic of 2.202 (P value = 0.02) and lateral ventricle volume demonstrating a statistic of 2.086 (P value = 0.03). Subsequent exploration using receiver operating characteristic analysis, with area under the curve of 0.71, identified 105.40 cm3 as the most robustly correlated volume threshold with responder status. CONCLUSIONS The lateral ventricular volume demonstrates a stronger correlation with gait improvement compared to the CA or EI. These observations indicate that evaluating the lateral ventricle volume before lumbar puncture could serve as a predictor for gait response after lumbar puncture in individuals with normal pressure hydrocephalus.

Abstract
PURPOSE/OBJECTIVE(S) MRI after chemoradiotherapy (chemoRT) shows areas of presumed tumor growth in ≤ 50% of glioblastoma (GBM) patients, which can be true progression (TP) - tumor growth with poor treatment response, or pseudoprogression (PP) - edema and tumor necrosis with favorable treatment response. Patients with TP have median overall survival (OS) of only 7 months, while patients with PP have median OS of 36 months. However, on imaging, TP and PP are usually not discernible during treatment, making it difficult to adapt radiation for poor responders. The purpose of this study was to investigate the prognostic value of delta radiomic features from MR-Linac for GBM. MATERIALS/METHODS Using an IRB-approved prospective cohort of GBM patients undergoing 30 fractions of chemoRT to 60 Gy on a 0.35T MR-Linac, 2 regions of interest (ROI) were contoured on daily T2-weighted treatment set-up scans: 1) tumor/edema (lesion) and 2) post-surgical resection cavity (RC). The lesion ROI were used to calculate texture features: second order radiomics features based on the gray-level co-occurrence matrix (GLCM), gray-level size zone matrix (GLSZM), gray-level run length matrix (GLRLM), and neighborhood gray-tone difference matrix (NGTDM). Each of these describe the probability of spatial relationships of gray levels occurring within the ROI. Features from fraction 1 (pre-radiation) were subtracted from fractions 5, 10, 15, 25, and 30 to create delta features at 5 timepoints (D5-D30). Patient response was retrospectively defined as no progression (NP), TP, or PP. Supervised machine learning was utilized using a 500-tree random forest (RF) classification model with TP or PP as the outcome. Variable importance analysis was conducted by calculating the out-of-bag errors with multiple bootstrapped data sets. The most prognostic features were selected using the RF importance scores. RESULTS Thirty-six patients were screened for inclusion: 9 were excluded due to no T2 lesion (RC ROI only). Of the remaining 27 patients: 10 had NP, 11 had TP, and 6 had PP. Thirty-nine texture features, plus lesion volume and mean lesion intensity (for a total of 41 variables per time point) were calculated and included in the model. Of the 10 most prognostic features, 6 were from D10, suggesting that prognostic changes in the underlying lesion microenvironment are occurring within the first 10 fractions of treatment. The model selected GLSZM high gray-level zone emphasis (HGZE) D10, IBSI code 5GN9, as the most prognostic feature. The receiver operator characteristic (ROC) area under the curve (AUC) for GLSZM HGZE D10 was 0.94 (95% CI = 0.81-1.00). CONCLUSION Delta radiomic features extracted from MR-Linac imaging may predict between PP and TP in GBM patients during treatment, which is earlier than current methods. This could allow physicians to adapt/intensify treatment in real time for poorly responding patients. Future directions include analysis with a larger patient cohort and with additional MRI contrasts (MR-Linac multiparametric MRI).

Evaluation of the national governmental efforts between 1997 and 2010 in reducing health inequalities in England. Public Health 2023; 218:128-135. [PMID: 37019028 DOI: 10.1016/j.puhe.2023.02.021] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2022] [Revised: 02/05/2023] [Accepted: 02/27/2023] [Indexed: 04/05/2023]
Abstract
OBJECTIVES The pandemic has compounded existing inequalities. In the UK, there have been calls for a new cross-government health inequalities strategy. This study aims to evaluate the effectiveness of national governmental efforts between 1997 and 2010, referred to as the National Health Inequalities Strategy (NHIS). STUDY DESIGN population-based observational study. METHODS Using Global Burden of Disease data, age-standardised years of life lost due to premature mortality (YLL) rates per 10,000 were extracted for 150 Upper Tier Local Authority (UTLA) regions in England for every year between 1990 and 2019. The slope index of inequality was calculated using YLL rates for all causes, individual conditions, and risk factors. Joinpoint regression was used to assess the trends of any changes which arose before, during or after the NHIS. RESULTS Absolute inequalities in YLL rates for all causes remained stable between 1990 and 2000, before decreasing over the following 10 years. After 2010, improvements slowed. A similar trend can be observed amongst inequalities in YLLs for individual causes, including ischaemic heart disease, stroke, breast cancer and lung cancer amongst females, and ischaemic heart disease stroke, diabetes and self-harm amongst males. This trend was also observed amongst certain risk factors, notably blood pressure, cholesterol, tobacco and dietary risks. Inequalities were generally greater in males than in females; however, trends were similar across both sexes. The NHIS coincided with significant reductions in inequalities in YLLs due to ischaemic heart disease and lung cancer. CONCLUSIONS The findings suggest that the NHIS coincided with a reduction in health inequalities in England. Policy makers should consider a new cross-government strategy to tackle health inequalities drawing from the success of the previous NHIS.

Abstract
BACKGROUND AND PURPOSE A scout accelerated motion estimation and reduction (SAMER) framework has been developed for efficient retrospective motion correction. The goal of this study was to perform an initial evaluation of SAMER in a series of clinical brain MR imaging examinations. MATERIALS AND METHODS Ninety-seven patients who underwent MR imaging in the inpatient and emergency department settings were included in the study. SAMER motion correction was retrospectively applied to an accelerated T1-weighted MPRAGE sequence that was included in brain MR imaging examinations performed with and without contrast. Two blinded neuroradiologists graded images with and without SAMER motion correction on a 5-tier motion severity scale (none = 1, minimal = 2, mild = 3, moderate = 4, severe = 5). RESULTS The median SAMER reconstruction time was 1 minute 47 seconds. SAMER motion correction significantly improved overall motion grades across all examinations (P < .005). Motion artifacts were reduced in 28% of cases, unchanged in 64% of cases, and increased in 8% of cases. SAMER improved motion grades in 100% of moderate motion cases and 75% of severe motion cases. Sixty-nine percent of nondiagnostic motion cases (grades 4 and 5) were considered diagnostic after SAMER motion correction. For cases with minimal or no motion, SAMER had negligible impact on the overall motion grade. For cases with mild, moderate, and severe motion, SAMER improved the motion grade by an average of 0.3 (SD, 0.5), 1.1 (SD, 0.3), and 1.1 (SD, 0.8) grades, respectively. CONCLUSIONS SAMER improved the diagnostic image quality of clinical brain MR imaging examinations with motion artifacts. The improvement was most pronounced for cases with moderate or severe motion.

Abstract
Abstract
Introduction
Recurrent episodes of aspiration pneumonia (RAP) are a significant problem in frail patients leading to high re-hospitalization and mortality. Anticipatory care planning (ACP) enables improved quality of life and end of life care. We reviewed the assessment, ACP discussions and communication with Primary Care in these patients.
Methods
We used a PDSA methodology, reviewing 116 patients with RAP referred to Speech and Language Therapy (SLT) in Elderly Medicine wards over six months, including the winter. Educational interventions were implemented. An illustrative case and pre-intervention results were presented at an online hospital-wide seminar and subsequently at an online departmental medical staff teaching session. Post-intervention analysis of 10 patients with RAP admitted over two summer months was conducted. The second round of interventions included departmental induction teaching for newly rotated doctors and creating an electronic ACP document (RAP ACP) for inclusion within the medical record.
Results
Baseline data was collected from 116 patients (mean age 85, 47% female). After the educational interventions, data was collected from 10 patients (mean age 88, 70% female). Data is being collected from winter months after the second intervention. This will be available before the conference. Baseline data demonstrated the need for improvements in documentation of Mental Capacity Assessment (MCA) specific to feeding (21.5%), ACP completion (26.7%) and flagging patients suitable for the Gold Standards Framework (GSF) on discharge (15%). Following educational interventions, there was a substantial improvement in MCA documentation (80%). Furthermore, there was a marked improvement in the completion of ACP discussions (70%). Communication of patients eligible for GSF was similar (14.2%) post-intervention.
Conclusions
Educational interventions substantially improved the quality of individualised care provided to patients with RAP. Mortality was high in both groups, yet documentation of eligibility for GSF was low, prompting further interventions targeting discharge communication.

Abstract
Abstract
Background
In the UK, chronic conditions such as cancer, heart disease, stroke, and chronic obstructive pulmonary disease are driving health inequalities in life expectancy and were responsible for two-thirds of premature mortality in 2017. Voices that stress the importance of primary care in reducing health inequalities have been strengthening during the last decade. However, defining the most effective strategies to reduce health inequalities through general practice remains a challenge.
Aims
This study examines the evidence on interventions in primary care that are likely to decrease inequalities in NCDs and especially cancer, diabetes, cardiovascular and chronic obstructive pulmonary disease and will provide healthcare organisations with guiding principles on what should be commissioned.
Methods
The study is a realist review following Pawson's model. Based on a programme theory, we screened systematic reviews of interventions delivered in primary care and through their references, we identified primary studies reporting on inequalities across PROGRESS-Plus criteria. The data were analysed in light of the initial program theory and organised in a model informed by Collins’ Domains of Power framework.
Results
Out of 251 included reviews we retrieved 6,555 primary studies which resulted in 333 studies for data extraction. We found that there are five guiding principles operating simultaneously across four different domains which can reduce health inequalities in General Practice. The principles include flexibility, continuity, inclusivity, intersectionality, and community and operate simultaneously across the domains of structures and policies; narratives and ideas; rules and practices; and relationships and experience.
Conclusions
Flexibility, continuity, inclusivity, intersectionality, and community are the five principles which should guide the design and delivery of General Practice for the reduction of health inequalities.
Key messages
• Flexibility, continuity, inclusivity, intersectionality, and community are the five principles which should guide the design and delivery of General Practice for the reduction of health inequalities.
• Action to reduce health inequalities should be taken simultaneously across the domains of structures and policies; narratives and ideas; rules and practices; and relationships and experience.

Abstract
Abstract
Improvements in life expectancy have slowed in high income countries, with uncertain causes. We assessed the contribution of different causes of death to changes in life expectancy, and changes in population exposure to major risk factors in 16 European Economic Area countries plus the 4 nations of the United Kingdom from 1990-2013 and 2013-2019, using the Global Burden of Disease Study. After decades of steady improvements in life expectancy, all countries experienced smaller annual improvements after 2013. Norway experienced the smallest mean annual rate of change in improvement from pre 2013 to post 2013 of 0.03 years, and Northern Ireland (followed closely by Scotland and England) experienced the largest annual reduction from pre to post 2013 of 0.25 years. The cause of death responsible for the largest reductions in life expectancy improvements after 2013 was cardiovascular disease, followed by neoplasms. The largest reductions in deaths from cardiovascular disease were attributable to seven major risk factors: high LDL cholesterol, tobacco, dietary risks, high fasting plasma glucose, high systolic blood pressure, high body mass index, and low physical activity. The risk factors for deaths from neoplasm were similar. Exposure to tobacco remains a high risk but exposure declined steadily. Exposure to the other risks generally worsened after 2013, particularly for BMI and high fasting plasma glucose. The European countries that had better maintained reductions in deaths from cardiovascular disease and neoplasms also experienced larger improvements in life expectancy. These changes were underpinned by changing exposure to major risks. Policy responses to the slowdown in life expectancy improvements should include reducing population exposure to major risks, including the broader risks from diet and low physical activity, through prevention and addressing the broad social and commercial determinants of health as well as adequate funding for health services.

Abstract
Neuroimaging serves a variety of purposes in Alzheimer's disease (AD) and related dementias (ADRD) research - from measuring microscale neural activity at the subcellular level, to broad topological patterns seen across macroscale-brain networks, and everything in between. In vivo imaging provides insight into the brain's structure, function, and molecular architecture across numerous scales of resolution; allowing examination of the morphological, functional, and pathological changes that occurs in patients across different AD stages (1). AD is a complex and potentially heterogenous disease, with no proven cure and no single risk factor to isolate and measure, whilst known risk factors do not fully account for the risk of developing this disease (2). Since the 1990's, technological advancements in neuroimaging have allowed us to visualise the wide organisational structure of the brain (3) and later developments led to capturing information of brain 'functionality', as well as the visualisation and measurement of the aggregation and accumulation of AD-related pathology. Thus, in vivo brain imaging has and will continue to be an instrumental tool in clinical research, mainly in the pre-clinical disease stages, aimed at elucidating the biological complex processes and interactions underpinning the onset and progression of cognitive decline and dementia. The growing societal burden of AD/ADRD means that there has never been a greater need, nor a better time, to use such powerful and sensitive tools to aid our understanding of this undoubtedly complex disease. It is by consolidating and reflecting on these imaging advancements and developing long-term strategies across different disciplines, that we can move closer to our goal of dementia prevention. This short commentary will outline recent developments in neuroimaging in the field of AD and dementia by first describing the historical context of AD classification and the introduction of AD imaging biomarkers, followed by some examples of significant recent developments in neuroimaging methods and technologies.

Abstract
Abstract
Study question
Is men’s diet associated with assisted reproductive technology (ART) outcomes?
Summary answer
An empirical dietary score representing the overall effect of men’s diet on semen quality was unrelated to ART outcomes.
What is known already
Multiple studies have related various aspects of men’s diet to semen quality. Generally, healthier foods, such as fish, vegetables, and fruits, have been related to better semen quality, whereas unhealthy foods, like processed and red meats, have had the opposite relationship. Nevertheless, while bulk semen parameters are important biomarkers of male fertility and a diagnostic cornerstone for male factor infertility, they are imperfect predictors of a couple’s fertility.
Study design, size, duration
Couples presenting to the Massachusetts General Hospital Fertility Center between April 2007 and April 2018 were invited to participate in the Environment and Reproductive Health (EARTH) study, a prospective cohort study. Men’s diet was assessed with a previously validated food frequency questionnaire. A dietary score reflecting the overall relation of men’s food intake with semen quality parameters was empirically derived using reduced rank regression (RRR). The resulting dietary score was related to ART outcomes.
Participants/materials, setting, methods
We used information from 349 men (908 semen samples) to derive the empirical diet pattern and data from 231 couples (407 ART cycles). The primary outcome was the probability of live birth per treatment cycle; secondary outcomes were semen quality, and fertilization, implantation, and clinical pregnancy rates. We evaluated the association between the dietary score and these outcomes using logistic generalized linear mixed models to account for repeated cycles while adjusting for confounders.
Main results and the role of chance
Men had a median baseline age and BMI of 36.8 years and 26.9 kg/m2, respectively. The empirical diet pattern was significantly associated with all semen parameters. One standard deviation increase in the empirical diet pattern was associated with lower volume (–0.10 standard units [95% CI: –0.17 to –0.04]) and to higher sperm total sperm count (0.13 standard units [0.06 to 0.20]), concentration (0.17 standard units [0.10 to 0.24]), total motility (0.14 standard units [0.07 to 0.20]), progressive motility (0.08 standard units [0.01 to 0.15]), and normal morphology (0.18 standard units [0.11 to 0.25]). Couples with men in the lowest quartile of the empirical score were more likely to have a diagnosis of male infertility than couples with men in the highest quartile (49% vs 24%). Despite the association with semen parameters, the empirical diet score was not related to any clinical outcome of infertility treatment with ART. The adjusted probabilities of implantation, clinical pregnancy and live birth in the lowest and highest quartile of the empirical score were 0.62 (0.50–0.73) and 0.55 (0.45–0.66), 0.57 (0.46–0.69) and 0.50 (0.40–0.61), and 0.49 (0.37–0.62) and 0.36 (0.25–0.48), respectively. Analyses excluding couples with a diagnosis of male factor infertility yielded similar results.
Limitations, reasons for caution
We evaluated the relationship only among couples presenting to a fertility center and therefore it is unclear whether findings can be generalized to couples trying to conceive without ART.
Wider implications of the findings: Given ART is a robust intervention including stringent sperm selection procedures, any effect that empirical diet may have on a couple’s chances of conceiving through assisted reproduction is unlikely to reflect the effect of these factors on bulk semen quality parameters.

Abstract
Abstract
Study question
Is men’s adherence to the Mediterranean diet (MD) associated with sperm parameters and couples’ outcomes of assisted reproductive technologies (ART)?
Summary answer
Higher men’s adherence to the MD was associated with an increased probability of clinical pregnancy and live birth among couples undergoing ART.
What is known already
There is growing literature supporting the hypothesis that some nutrients, foods, and dietary patterns may be related to sperm quality and fertility. However, no previous studies analyzed the relationship of men’s adherence to the Mediterranean diet with sperm parameters and ART outcomes in the same cohort.
Study design, size, duration
The Environmental and Reproductive Health (EARTH) Study is a prospective preconception cohort of couples seeking fertility treatment at the Massachusetts General Hospital Fertility Center (Boston, USA). This analysis includes 314 men and their female partner, who underwent 791 ART cycles (2007–2020). Diet intake was measured by a validated semi-quantitative food frequency questionnaire completed prior to ART. Men’s adherence to the MD was estimated using the Trichopoulou score.
Participants/materials, setting, methods
Primary outcomes included: conventional sperm parameters (volume, sperm count, concentration, motility, and morphology), and ART outcomes (implantation, clinical pregnancy, and live birth). We estimated the marginal means and 95% confidence interval (95%CI) for semen parameters and the probability of ART (95%CI) by employing generalized linear mixed models while adjusting for several potential confounders. Sensitivity analyses by changing the cut-off points of adherence to the MD were tested.
Main results and the role of chance
At baseline, men had a median (IQR) age of 35.6 (32.6, 38.8) years and a BMI of 26.7 (24.0, 29.4) kg/m2. Female partner age median (IQR) was 35.0 years (32.0, 38.0) and BMI 23.3 (21.3, 26.6) kg/m2. Couples were mostly white and had never smoked. Men’s adherence to the MD was not associated with seminal parameters in the multivariable-adjusted models but it was related to a higher probability of clinical pregnancy and live birth. The predicted marginal proportions and confidence intervals among men in the lowest compared with the highest quartile of adherence to the MD were 0.25 (0.14, 0.40), 0.55 (0.41, 0.68) for clinical pregnancy (P-trend=0.005), and 0.19 (0.10, 0.32), 0.42 (0.30, 0.55) for live birth (P-trend=0.014). Male partner MD dietary pattern scores were unrelated to the probability of implantation. Sensitivity analyses using tertiles and quintiles of men’s adherence to the MD showed similar associations.
Limitations, reasons for caution
Although we have adjusted our models by several potential confounding factors, residual confounding cannot be ruled out, and therefore our results should be interpreted with caution. The findings may not be generalizable to other populations or couples attempting conception without ART.
Wider implications of the findings: According to our knowledge, this is the first study suggesting that adherence to MD could be suitable dietary guidance for men whose partners are undergoing infertility treatment.

Abstract
Abstract
Introduction
Advanced Care Planning (ACP) is well established for patients with terminal cancer diagnoses but is poorly utilised when caring for elderly patients with other terminal illnesses. We aimed to assess the effectiveness of ACP in our older, community dwellers following a period of increased awareness.
Methods
A closed loop audit was undertaken, assessing deaths from a dementia care home within rural Norfolk, before and after implementation of an education and focus programme (cycle 1=Jan 2017-Jan 2018, cycle 2: Feb 2018-Jan-2019). Deceased patients were identified from care home records and data from electronic hospital and general practice records were analysed. Results were compared according to existing guidance outlined in the Palliative Gold Standards Framework (GSF) and Department of Health End of Life Care Strategy 2009. Compliance between cycles was compared using the chi-square test with p=.05 indicative of statistical significance.
Results
59 patients were included (median age=84, male=31). Results of the audit for each criterion are shown in table 1. More patients achieved their preferred place of care (PPOC) following the implementation of the education programme, with access to end of life medications significantly improving.
Conclusions
Increasing awareness and understanding of ACP in the community has been shown to improve compliance with GSF standards, particularly access to end of life medications. Further efforts are still required to improve care and a third cycle is scheduled for January 2020, following further training.

Impact of contouring variability on oncological PET radiomics features in the lung. Sci Rep 2020; 10:369.

Abstract
Radiomics features extracted from oncological PET images are currently under intense scrutiny within the context of risk stratification for a variety of cancers. However, the lack of robustness assessment poses problems for their application across institutions and for broader patient populations. The objective of the current study was to examine the extent to which radiomics parameters from oncological PET vary in response to manual contouring variability in lung cancer. Imaging data employed in the study consisted of 26 PET scans with lesions in the lung being created through the use of an anthropomorphic phantom in conjunction with Monte Carlo simulations. From each of the simulated lesions, 25 radiomics features related to the gray-level co-occurrence matrices (GLCOM), gray-level size zone matrices (GLSZM), and gray-level neighborhood difference matrices (GLNDM) were extracted from ground truth contour and from manual contours provided by 10 raters in regard to four intensity discretization schemes with number of gray levels of 32, 64, 128, and 256, respectively. The impact of interrater variability in tumor delineation upon the agreement between raters on radiomics features was examined via interclass correlation and leave-p-out assessment. Only weak and moderate correlations were found between segmentation accuracy as measured by the Dice coefficient and percent feature error from ground truth for the vast majority of the features being examined. GLNDM-based texture parameters emerged as the top performing category of radiomcs features in terms of robustness against contouring variability for discretization schemes engaging number of gray levels of 32, 64, and 128 while GLCOM-based parameters stood out for discretization scheme engaging 256 gray levels. How and to what extent interrater reliability of radiomics features vary in response to the number of raters were largely feature-dependent. It was concluded that impact of contouring variability on PET-based radiomics features is present to varying degrees and could be experienced as a barrier to convey PET-based radiomics research to clinical relevance.

Abstract
Abstract
Background
Life expectancy improvements have slowed down in several European countries since around 2011. The relative contributions from changes in specific conditions (e.g. cancers) and broader risk factors (e.g. smoking or austerity) remain unclear. We aimed to explore the different potential causes in 17 European Economic Area (EEA) countries.
Methods
We compared Global Burden of Disease (GBD) study estimates for life expectancy, years of life lost (YLLs) and population attributable fractions (PAFs) for risk factors, for 2005-2011 and 2011-2017 for 17 EEA countries. Three countries with the largest absolute improvements and three with the smallest were selected for analysis by gender, age, condition and risk factors.
Results
Norway, France and Belgium had the largest improvement in life expectancy (+1.5, +1.2 and +1.2 years respectively) from 2011 to 2017, and Germany, Iceland and the UK the smallest (+0.1, +0.2 and +0.2 years). Life expectancy reduced slightly for women aged over 80 in Germany and UK, men aged over 50 in Germany, and for men in all age groups up to 90 years in Iceland. Norway, France and Belgium saw faster improvements in YLLs from lung cancer and Norway and France for COPD in both men and women, and from self-harm in men, after 2011 than before. PAF for tobacco declined faster after 2011. Germany, Iceland and the UK saw slower improvements in cardiovascular disease and in Germany and the UK lung cancer. In Iceland, YLLs for cancers, self harm, respiratory disease, cirrhosis and dementia all worsened after 2011. PAF for tobacco remained high or declined less after 2011 in all 3 countries. PAFs for alcohol and drug use remained high in Iceland and UK.
Conclusions
Differential changes in major fatal diseases and risk factors help explain national changes in life expectancies, but national differences in data availability may affect results. Further research is needed into the ‘causes of the causes’, such as the 2008 economic crash in Iceland.
Key messages
Differential changes in major fatal diseases and risk factors help explain national changes in life expectancies. Norway, France and Belgium had the largest improvement in life expectancy from 2011 to 2017, and Germany, Iceland and the UK the smallest.

Abstract
Abstract
Immune checkpoint inhibitor (ICI) therapies have led to remarkable clinical responses in cancers such as melanoma and non-small cell lung cancer. In breast cancer, current immunotherapy trials have placed an emphasis on triple negative breast cancers (TNBC), where early results suggest response rates of 10-20%. Thus, it is critical to identify predictive biomarkers to enhance patient selection for immunotherapy. With this goal in mind, we simulated a clinical trial employing anti-PD1 and anti-CTLA therapies in immune-intact genetically engineered mouse models (GEMMs) of TNBC. Testing of ICI therapies on 8 different GEMMs demonstrated that each model was resistant. Whole exome sequencing showed that each model also harbored a low mutation burden. Given that mutation load is predictive of immunotherapy response in other cancer types, and that Apobec3B activity is associated with higher tumor mutation burden (TMB) in breast cancer, we created two different tumor lines with overexpression of murine Apobec3.
In contrast to the parental lines, the Apobec3 overexpressing lines showed an elevated tumor mutation burden and new mutations were consistent with the Apobec mutation signature. These TNBC lines with new mutations resulting from Apobec3 activity were exquisitely sensitive to anti-PD1/anti-CTLA4 combination therapy; as assessed by reduction in tumor volume and extended overall survival. To identify features that predict response, we examined resistant and sensitive tumors at pretreatment, at 1 week of treatment, and at end stage by flow cytometry and mRNA-seq. Gene expression profiling identified multiple immune signatures as predictive of response to ICI therapy; specifically CD8+ T-effector memory cells, CD4+ T-cells, and activated B-Cells. Similarly, gene expression analysis showed that these cell types increased at 1 week of therapy in sensitive models but not in resistant models. Flow cytometry confirmed these predictions.
Next, we used an antibody based approach to separately deplete CD4+ T-Cells, CD8+ T-cells, or B-cells in Apobec3 mutagenized murine tumors receiving aPD1/aCTLA4 combination therapy. In each case, depletion of these populations significantly reduced the therapeutic response. However, mice receiving combination immunotherapy and depleted for CD8+ T-cells still exhibited a significant extension in overall survival compared to non-treated controls. In contrast, the CD4+ T-cell depleted mice and B-cell depleted mice exhibited no ICI therapeutic benefit.
Together, these data point to key immune biomarkers of response to anti-PD1/anti-CTLA4 therapy; we have further developed a genomic predictor of ICI response using our murine models and will test this on a human TNBC data set. Lastly, this GEMM system provides a rich RNA-seq resource, and new immune-activated models for TNBC, which uncovered a key role for B-cells and CD4+ T-cells in response to ICI therapies.

Abstract
Purpose To establish the performance of screening with serum cancer antigen 125 (CA-125), interpreted using the risk of ovarian cancer algorithm (ROCA), and transvaginal sonography (TVS) for women at high risk of ovarian cancer (OC) or fallopian tube cancer (FTC). Patients and Methods Women whose estimated lifetime risk of OC/FTC was ≥ 10% were recruited at 42 centers in the United Kingdom and underwent ROCA screening every 4 months. TVS occurred annually if ROCA results were normal or within 2 months of an abnormal ROCA result. Risk-reducing salpingo-oophorectomy (RRSO) was encouraged throughout the study. Participants were observed via cancer registries, questionnaires, and notification by centers. Performance was calculated after censoring 365 days after prior screen, with modeling of occult cancers detected at RRSO. Results Between June 14, 2007, and May 15, 2012, 4,348 women underwent 13,728 women-years of screening. The median follow-up time was 4.8 years. Nineteen patients were diagnosed with invasive OC/FTC within 1 year of prior screening (13 diagnoses were screen-detected and six were occult at RRSO). No symptomatic interval cancers occurred. Ten (52.6%) of the total 19 diagnoses were stage I to II OC/FTC (CI, 28.9% to 75.6%). Of the 13 screen-detected cancers, five (38.5%) were stage I to II (CI, 13.9% to 68.4%). Of the six occult cancers, five (83.3%) were stage I to II (CI, 35.9% to 99.6%). Modeled sensitivity, positive predictive value, and negative predictive value for OC/FTC detection within 1 year were 94.7% (CI, 74.0% to 99.9%), 10.8% (6.5% to 16.5%), and 100% (CI, 100% to 100%), respectively. Seven (36.8%) of the 19 cancers diagnosed < 1 year after prior screen were stage IIIb to IV (CI, 16.3% to 61.6%) compared with 17 (94.4%) of 18 cancers diagnosed > 1 year after screening ended (CI, 72.7% to 99.9%; P < .001). Eighteen (94.8%) of 19 cancers diagnosed < 1 year after prior screen had zero residual disease (with lower surgical complexity, P = .16) (CI, 74.0% to 99.9%) compared with 13 (72.2%) of 18 cancers subsequently diagnosed (CI, 46.5% to 90.3%; P = .09). Conclusion ROCA-based screening is an option for women at high risk of OC/FTC who defer or decline RRSO, given its high sensitivity and significant stage shift. However, it remains unknown whether this strategy would improve survival in screened high-risk women.
