Abstract
INTRODUCTION Many patients at very high risk of cardiovascular (CV) events would benefit from lipid-lowering therapies (LLT) intensification to decrease their risk. This study aimed to identify the real-world secondary prevention patients potentially eligible for proprotein convertase subtilisin-kexin type 9 inhibitors (PCSK9i) in Spain. METHODS This retrospective cohort study included adult patients registered in the IQVIA Spanish Electronic Medical Records outpatient database (2014-2020), diagnosed with myocardial infarction (MI), unstable angina (UA), ischaemic stroke (IS), transient ischaemic attack (TIA) or peripheral artery disease (PAD) and with ≥ 1 low-density lipoprotein cholesterol (LDL-C) or total cholesterol measurements. Longitudinal data were collected from the initial diagnosis to the end of the study period or follow-up loss. RESULTS The study included 9516 patients, 63.9% male, mean (SD) age 67.7 (12.5) years and mean LDL-C 117.3 (38.8) mg/dL. MI, IS and PAD were the most severe events reported during the study period (28.5%, 18.7% and 29.3% of patients, respectively). At the time of last available LDL-C assessment (≥ 3 months post-event), 64.4% patients were on LLT. Of those, 45.4%, 46.9% and 7.7% were on high-, moderate- and low-intensity LLT. Overall, 9.6% patients achieved LDL-C < 55 mg/dL (24.2% LDL-C < 70 mg/dL). Furthermore, 17.9% patients receiving optimized oral LLT showed LDL-C > 100 mg/dL (LDL-C reimbursement threshold for PCSK9i in Spain). CONCLUSION Up to 82% of patients with atherosclerotic CV disease do not achieve LDL-C levels recommended by the 2019 ESC/EAS guidelines despite being on optimized oral LLT therapy. In 17.9% of these patients LDL-C levels exceed 100 mg/dL, being eligible for PCSK9i in Spain.

Abstract
INTRODUCTION The 2019 European Society of Cardiology and European Atherosclerosis Society (2019 ESC/EAS) guidelines stress the importance of managing low-density lipoprotein cholesterol (LDL-C) after myocardial infarction (MI) to reduce the risk of cardiovascular events. Information on guideline implementation is limited. The aim of this survey was to describe current clinical practice regarding LDL-C management in the first year post-MI across Europe, improving understanding of the role of ESC/EAS guidelines on clinical practice. METHODS A qualitative web-based cross-sectional physician survey about the patient pathway and LDL-C management post-MI was conducted in 360 physicians from France, Italy, Germany, The Netherlands, Spain, and the UK (n = 60/country) between December 2019 and June 2020. Secondary and primary care physicians (SCPs/PCPs) described their experiences treating patients post-MI over the preceding 2 months. RESULTS Physicians reported that on average 90.7% of patients not prescribed lipid-lowering therapy (LLT) before an MI initiated LLT as inpatients; for patients already taking LLT, treatment was intensified for 64.7% of inpatients post-MI. SCPs reported prescribing higher-intensity statins and/or ezetimibe for between 72.3% (Italy) and 88.6% (UK) of patients post-MI. More than 80.0% of SCPs and 51.2% of PCPs stated that they would initiate a change in LLT immediately if patients did not achieve their LDL-C treatment goal by 12 weeks post-MI; 82.0% of SCPs and 55.1% of PCPs reported referring to 2019 ESC/EAS guidelines for management of patients post-MI. Barriers to initiating PCSK9 inhibitors (PCSK9is) included prior prescription of a maximally tolerated dose of statin (49.4%) and/or ezetimibe (38.9%), requirement to reach threshold LDL-C levels (44.9%), and pre-authorization requirements (30.4%). CONCLUSION Differences in clinical practice post-MI were reported across the countries surveyed, including divergence between 2019 ESC/EAS and local guidelines. Increased use of innovative medicines to achieve LDL-C goals should reduce risk of subsequent cardiovascular events in very high-risk patients post-MI.

Abstract
OBJECTIVES To compare treatment patterns, risk factors and cardiovascular disease (CVD) event rates in the UK from 2008 to 2017. DESIGN Retrospective cohort study using the Clinical Practice Research Datalink. SETTING UK primary care. PARTICIPANTS We selected 10 annual cohorts of patients with documented CVD receiving lipid-lowering therapy and the subsets with myocardial infarction (MI). Each cohort included patients ≥18 years old, with ≥1 year of medical history and ≥2 lipid-lowering therapy prescriptions in the prior year. PRIMARY AND SECONDARY OUTCOME MEASURES For each annual cohort, we identified cardiovascular risk factors and lipid-lowering therapy and estimated the 1-year composite rate of fatal and non-fatal MI, ischaemic stroke (IS) or revascularisation. RESULTS The documented CVD cohort mean age was 71.6 years in 2008 (N=173 424) and 72.5 (N=94 418) in 2017; in the MI subset, mean age was 70.1 years in 2008 (N=38 999) and 70.4 in 2017 (N=25 900). Both populations had larger proportions of men. In the documented CVD cohort, the proportion receiving high-intensity lipid-lowering therapy from 2008 to 2017 doubled from 16% to 32%; in the MI subset, the increase was 20% to 48%. In the documented CVD cohort, the proportion of patients with low-density lipoprotein cholesterol (LDL-C) <1.8 mmol/L increased from 28% to 38%; in the MI subset, the proportion with LDL-C <1.8 mmol/L increased from 32% to 42%. The composite event rate per 100 person-years declined over time, from 2.5 to 2.0 in the documented CVD cohort, and from 3.7 to 2.8 in the MI subset. After excluding revascularisation from the composite outcome, the decline in the event rate in both populations was substantially attenuated. CONCLUSIONS Despite an increase in high-intensity therapy use and a decline in revascularisation, more than half of patients did not receive high-intensity lipid-lowering therapy by 2017 and incidence rates of MI and IS remained virtually unchanged.

Abstract
OBJECTIVES We assessed healthcare resource utilization (HCRU) and costs of cardiovascular (CV) events in patients with a history of atherosclerotic cardiovascular disease (ASCVD) in Germany. METHODS We conducted a retrospective matched case-control study based on German claims data from 1 January 2012 to 31 December 2017 using the "Institute for Applied Health Research Berlin" (InGef) Research Database. Cases who had a myocardial infarction (MI), stroke and angina pectoris identified by ICD-10-GM codes between 1 January 2014 and 31 December 2016 were matched to event-free controls by an exact matching approach without replacement at a ratio of 1:2. Costs and HCRU were assessed in individual 1-year follow-up periods after the index event for the overall cohort and subgroups of MI cases and stroke cases. RESULTS The overall cohort consisted of a total of 14,169 cases with a CV index event matched to 28,338 controls. The mean age of the overall cohort was 73.3 years, 34.1% of the patients were female, 3,717 (26.2%) had an MI, and 3,752 (26.5%) had stroke. Following the index events, 12.2% of cases in the overall cohort, 12.6% of MI cases, and 8.7% of stroke cases experienced a recurrent CV event. CV cases had on average 1.7 more all-cause hospitalizations (p <0.001) and 6.1 more outpatient visits (p <0.001) during the 1-year follow-up period than did controls. In the MI and stroke subgroups, cases had on average 1.8 and 1.6 more all-cause hospitalizations and 7.0 and 4.0 more outpatient visits, respectively (differences were statistically significant). Compared to controls, cases incurred on average higher total healthcare costs: by €11,898 for overall cases, by €16,349 for MI, and by €14,360 in stroke cases (overall: p <0.001; MI: p <0.001; stroke: p <0.001). CONCLUSION CV events in ASCVD patients pose a considerable clinical burden on patients and cause significant costs for the German statutory healthcare system.

Abstract
Introduction Atherosclerotic cardiovascular disease (ASCVD) is the leading cause of mortality in Italy, accounting for 22% of total deaths. Lowering low-density lipoprotein cholesterol (LDL-C) levels reduces the risk of cardiovascular (CV) events; thus, lipid-lowering therapy (LLT) is the first-line treatment for patients with ASCVD and hypercholesterolaemia. However, many patients with ASCVD fail to reach LDL-C treatment thresholds, leaving them at greater risk of CV events. Inpatient care accounts for 51% of total expenditure on cardiovascular disease in the European Union, but healthcare resource utilization (HCRU) data for ASCVD in Italy is limited. Methods The study analysed healthcare claims data for 17,881 patients with acute coronary syndrome, ischemic stroke or peripheral artery disease from the Umbria 2 and Marche regions of Italy. LLT treatment patterns and CV event rates were collected and HCRU estimated in the year before and after the index event. Results High-intensity LLTs were prescribed to 44.3% of patients and 49.6% received moderate-/low-intensity LLTs during the 6 months after the index event. The first year CV event rate was 18.0/100 patient-years for patients receiving high-intensity LLTs and 17.2/100 patient-years for those on moderate-/low-intensity LLTs. Higher costs were associated with patients untreated with LLT 6 months post-index event (€8323) than patients prescribed high-intensity (€6278) or moderate-/low-intensity LLTs (€6270). Hospitalization accounted for most of the total costs. Conclusions This study found that CV events in secondary prevention Italian patients are associated with substantial HCRU and costs. More intensive LDL-C lowering can prevent CV events, easing the financial burden on the healthcare system.

Abstract
Abstract
Background and aims
Statins are the standard of care for patients with dyslipidemia, but some patients develop intolerance to treatment. The experience of statin intolerant (SI) patients is poorly understood. The objective of this study was to identify key aspects of SI that may be associated with treatment discontinuation.
Methods
Using a previously created questionnaire, we conducted a pilot cross-sectional survey to identify items important for describing patient-centric aspects of SI. The study recruited adult (18+) patients with a history of statin-associated side effects from 9 clinics in 6 countries (France, Italy, Norway, Spain, Sweden, and the United Kingdom), who had received statin treatment within the previous two years.
Results
We surveyed 104 patients (mean age 61.5 SD=11.2 years, 63.5% men, 50% currently on statins). Patients most frequently reported muscle-related symptoms: pain (90.9%), cramps (63.7%), and stiffness (58.2%). Using a 0–10 point scale, significant differences were found between those continuing versus discontinuing their statins for being bothered by side effects (7.5 vs 9.2, p=0.001), for an inability to tolerate side effects (6.7 vs 9.0, p<0.001), and those having too much side effects interference with their daily life (5.7 vs 8.6, p<0.001; see figure). For patients whose doctors worked on adjusting statin regimen, 67% stayed on treatment; for those whose doctors did not, only 10% continued treatment.
Conclusions
Results of this pilot survey suggest patients who experience greater side effects severity and interference with daily activity, along with lower efforts by clinicians to work with adjusting their statin regimen, are at greater risk for discontinuing treatment. A wider survey and larger study population is needed to confirm the results of this pilot study.

Abstract
Acute coronary syndrome (ACS) is highly prevalent in Switzerland and a leading cause of death. Associated productivity loss and indirect costs have rarely been studied. We investigated these factors in the first year after ACS in 24 Swiss patients (mean (SD) age 56 (8) years, 79% male). Data on patient productivity loss, absenteeism, presenteeism and caregiver assistance, were collected with the Productivity Cost Questionnaire during a routine cardiologist visit 3 to 12 months after hospitalisation for ACS and at least 4 weeks after patients returned to work. To estimate costs, lost hours were converted into 8-hour workdays, pro-rated to 1 year, combined with time off work due to initial hospitalisation and sick leave, and valued at Swiss labour costs. Additional data came from medical records. ACS patients lost on average (SD, range) 79 (81, 0.3–294) workdays; 38 (36, 0.3–153) days due to the initial hospitalisation and sick leave, 37 (75, 0–243) due to absenteeism after patients returned to work, and 4 (11, 0–41) due to presenteeism. Caregivers lost 10 (23, 0–90) additional workdays. The total indirect costs amounted to CHF 43,205 (44,026, 122–148,648); including CHF 18,514 (17,507, 122-74,619) for initial hospitalisation and sick leave and CHF 17,988 (36,394, 122–143,277) and CHF 1,849 (5181, 0–20,158) for absenteeism and presenteeism after patients returned to work, respectively. Costs of caregiver assistance amounted to CHF 4,855 (11,015, 0–43,843). This study showed that ACS patients lost on average 36% of their annual productive time. Caregivers lost an additional 5%. Lost work time was associated with substantial indirect costs that exceeded estimates of direct costs for ACS during 1 year. This suggests that costs and burden could be reduced through better risk reduction management.

Abstract
Abstract
Background
Over time, guidelines for dyslipidemia management in patients at high risk of atherosclerotic cardiovascular disease (CVD) changed with the goal of improving patient outcomes. Guidelines have been released by the European Joint Task Force in 2007, 2012 and 2016, European Society of Cardiology in 2011, 2016 and 2019, Joint British Societies in 2014, and National Institute for Health and Care Excellence in 2014.
Purpose
Evaluate cardiovascular risk factors, treatment patterns, and cardiovascular outcomes over time related to dyslipidemia management.
Methods
Ten prevalent cohorts of patients with documented CVD receiving lipid-lowering therapy (LLT) were created using Clinical Research Practice Datalink (CPRD) records as of January 1, each year from 2008 through 2017. For each cohort, we identified CVD risk factors and LLT, and estimated the 1-year composite rate of fatal and nonfatal myocardial infarction (MI), ischemic stroke (IS), or revascularization. Patient follow-up was censored at the earliest of one year, end of data, or the outcome of interest. Patients in each cohort were required to be ≥18 years old, have ≥1 years of available medical history, and have received ≥2 LLT prescriptions in the prior year. Documented CVD was defined as MI, IS, angina, revascularization, transient ischemic attack, carotid stenosis, abdominal aortic aneurysm, or peripheral arterial disease. Patients could be in multiple cohorts.
Results
Annual patient counts ranged from 170,501 to 179,137 through 2013 and declined to 94,418 by 2017 (due to fewer patients in the overall CPRD data). Comparing 2008, 2011 (when ESC guidelines were revised) and 2017 showed the following for CVD risk factors: mean age was 71.6, 72.3, and 72.5 years; males were 59.9%, 61.1%, and 63.1%; current smoking was 15.1%, 15.2%, and 13.9%; type 2 diabetes was 18.4%, 20.2%, and 22.4%; stage 3–5 chronic kidney disease was 22.4%, 25.1%, and 22.8%; history of MI was 22.5%, 23.9%, and 27.4%; history of IS was 5.5%, 6.6%, and 7.9%; LDL <1.8 mmol/L was 27.8%, 29.2% and 37.2%; and LDL <1.4 mmol/L was 9.9%, 10.1%, and 15.6%. In terms of treatment, high intensity statin use increased from 12.9% to 15.7% to 30.8%; atorvastatin 40–80 mg use increased from 12.9% to 15.5% to 30.5%; while simvastatin 20–40 mg use decreased from 55.4% to 58.8% to 36.7%. The 1-year cardiovascular event rate declined from 2.54 to 2.35 to 1.96 events per 100 person-years (Figure).
Conclusions
After 2011 in the UK, there was an increased use of high intensity statins, a greater proportion of patients with LDL levels <1.8 and <1.4 mmol/L, and lower 1-year cardiovascular event rates. While improved CVD management likely contributed to the event rate decline, less than 40% of very high-risk patients achieved an LDL <1.8 mmol/L, and the proportion with LDL <1.4 mmol/L, as recommended by the 2019 ESC guidelines, was less than 20%. Clinicians should continue their efforts to reduce LDL in these patients.

Abstract
Introduction
Both intensity and adherence to lipid lowering therapies (LLT) play an important role in effectiveness of the therapies in patients at risk for cardiovascular events.
Purpose
To evaluate the association of adherence and treatment intensity with cardiovascular outcomes and all-cause mortality in very high-risk patients (as defined by the current ESC guidelines) treated with statin and/or ezetimibe.
Methods
Retrospective cohort study was based on German health claims data (2010–2015) obtained from German Institute for Health Research (InGef) database and included patients ≥18 years with an initial LLT treatment (statin and/or ezetimibe) in 2011–2013, and diagnoses of cardiovascular disease (CVD), stage 4 or 5 chronic kidney disease (CKD) or type 2 diabetes mellitus (DM). Patients must have had at least 2 LLT prescriptions in the first year to ensure intention of treatment. Follow-up period started 1 year after the second LLT prescription and continued until one of the events of the composite study endpoint (hospitalisation for myocardial infarction, unstable angina, ischemic stroke, heart failure, revascularization, or all-cause death) or 31.12.2015, whichever occurred earlier. Adherence was measured annually by the proportion of days covered (PDC) using prescription data. Treatment intensity was quantified based on expected LDL-C reduction as described in the American College of Cardiology and American Heart Association (ACC/AHA) 2018 guidelines. Adherence and treatment intensity were multiplied to create a combined measure of intensity after accounting for adherence.
Results
73,257 patients of the CVD cohort were 68 (SD=12) years old, 59% men; the DM cohort (no CVD) had 13,584 patients, age 64 (10), 47% men; 472 patients in the CKD cohort (no CVD) were 65 (15) years old, 46% men. In a Cox proportional hazards model, each 10% increase in treatment intensity (LDL-C lowering) was associated with 18% lower risk of CV event in the CVD (HR 0.82, 95% CI 0.82–0.83), 21% - in the DM (HR 0.79, 95% CI 0.76–0.83), and 15% - in the CKD (HR 0.85, 95% CI 0.75–0.97) cohorts. Similarly, each 10% increase in adherence (PDC) was associated with 6% lower risk of CV event in the CVD (HR 0.94, 95% CI 0.93–0.94), 7% - in the DM (HR 0.93, 95% CI 0.91–0.94), and 7% - in the CKD (HR 0.93, 95% CI 0.89–0.97) cohorts. Each 10% increase in adherence-adjusted intensity was associated with 16% lower risk of CV event in the CVD (HR 0.84, 95% CI 0.83 - 0.85), 19% - in the DM (HR 0.81, 95% CI 0.78–0.85), and 17% - in the CKD (HR 0.83, 95% CI 0.72–0.96) cohorts. The models controlled for age, sex, Charlson comorbidity index and other cardiovascular risk factors at baseline.
Conclusions
A higher adherence and/or treatment intensity of LLT was associated with significantly lower risk of CV outcomes or all-cause death in German very high-risk patients. Strategies to tailor intensity to patient profile and improve adherence could further lower risk of CV events.

Abstract
OBJECTIVE To assess the prevalence of patients at very high risk of cardiovascular (CV) events in the United Kingdom (UK) and evaluate low-density lipoprotein cholesterol (LDL-C) values and treatment patterns in these patients. METHODS This cross-sectional study used primary care data from UK electronic medical records in the Clinical Practice Research Datalink (CPRD) in 2013. Very high-risk patients were defined per European Society of Cardiology guidelines as those with hyperlipidemia (assessed by co-medication) and documented cardiovascular disease (CVD) or hyperlipidemia and type 2 diabetes (DM2) without CVD (DM2w/oCVD). All analyses were descriptive. RESULTS Data from 4,940,226 patients were captured in the CPRD in 2013. Of these, 5% of patients had received ≥2 lipid-modifying therapy prescriptions and were at very high risk of CVD (3% [n = 138,536] had documented CVD, 2% [n = 98,743] had DM2w/oCVD). In documented CVD patients, coronary artery disease (73%) was the most frequent type of event (25% had myocardial infarction [MI]), followed by cerebrovascular disease (18%), and peripheral arterial disease (9%); 21% had experienced multiple CV events, 25% had DM2, and 3% had MI within 1 year. In documented CVD and DM2w/oCVD patients, >95% received statin treatment; 24% received high-intensity statin, and 1.5% statin plus ezetimibe. Across both populations, 64-66% had LDL-C levels ≥1.8 mmol/L, 27-28% ≥2.5 mmol/L, 6-7% ≥3.5 mmol/L, and 3% had levels ≥4.0 mmol/L, respectively. CONCLUSION A well-defined proportion of patients remain at very high-risk of CVD. Statin therapy needs optimization, but, for some patients with high LDL-C levels, multiple CV events, MI within 1 year, or CVD and DM2, additional more intensive therapy may be needed.

Abstract
UNLABELLED In this double-blind RCT, 4-month treatment with calcifediol compared with vitamin D3 improved gait speed by 18% among young postmenopausal women. Consistently, change in 25(OH)D blood levels over time were significantly correlated with improvement in gait speed in these women. No effect could be demonstrated for trunk sway. INTRODUCTION The aim of this study is to test the effect of calcifediol compared with vitamin D3 on gait speed and trunk sway. METHODS Twenty healthy postmenopausal women with an average 25(OH)D level of 13.2 ng/ml (SD = ±3.9) and a mean age of 61.5 years (SD = ±7.2) were randomized to either 20 μg of calcifediol or 20 μg (800 IU) of vitamin D3 per day in a double-blind manner. At baseline and at 4 months of follow-up, the same physiotherapist blinded to treatment allocation tested 8-m gait speed and a body sway test battery (Sway star pitch and roll angle plus velocity while walking 8 m, and standing on both legs on a hard and soft surface). All analyses adjusted for baseline measurement, age, and body mass index. RESULTS Mean 25(OH)D levels increased to 69.3 ng/ml (SD = ±9.5) in the calcifediol group and to 30.5 ng/ml (SD = ±5.0) in the vitamin D3 group (p < 0.0001). Women receiving calcifediol compared with vitamin D3 had an 18% greater improvement in gait speed at 4-month follow-up (p = 0.046) adjusting for baseline gait speed, age, and body mass index. Also, change in gait speed was significantly correlated with change in serum 25(OH)D concentrations (r = 0.5; p = 0.04). Across three tests of trunk sway, there were no consistent differences between groups and no significant correlation between change in 25(OH)D serum concentrations and change in trunk sway. CONCLUSIONS Calcifediol improved gait speed in early postmenopausal women compared with vitamin D3 and change in 25(OH)D level was moderately correlated with improvement in gait speed. A benefit on trunk sway could not be demonstrated.

Abstract
OBJECTIVE Several studies suggest that patients with ankylosing spondylitis (AS) have an increased risk of cardiovascular disease. This study aimed to evaluate the effects of a 12-week, individually monitored, with moderate heart rate level intensity cardiovascular training on cardiovascular fitness and perceived disease activity in AS patients. METHODS Patients diagnosed with AS according to the modified New York criteria were randomized to either cardiovascular training or attention control. The training group performed 3 cardiovascular training units per week. All participants attended 1 weekly usual care flexibility training session. Attention control contained regular discussion groups on coping strategies. Adherence was self-monitored. Assessments were performed at baseline and after the intervention period of 3 months. Physical fitness was the primary end point, measured in watts using a submaximal bicycle test following the physical work capacity 75% protocol. All analyses controlled for sex, age, body mass index,baseline fitness and physical activity levels, and Bath Ankylosing Spondylitis Disease Activity Index (BASDAI). RESULTS Of 106 AS patients enrolled, 40% were women and the mean ± SD age was 49 ± 12 years. A total of 74.6% of the training group reported exercising at least 3 times a week. At the 3-month followup, the fitness level in the training group was significantly higher than in the control group (mean ± SE 90.32W ± 4.52W versus 109.84W ± 4.72W; P = 0.001), independent of other covariates. The mean BASDAI total score was 0.31 points lower (P = 0.31) in the training group, reaching significance for the peripheral pain subscore (1.19; P = 0.01) but not for back pain or fatigue. CONCLUSION Cardiovascular training, in addition to flexibility exercise, increased fitness in AS patients and reduced their peripheral pain.

Abstract
We developed a user-friendly Internet-based tool for patients undergoing total hip replacement (THR) due to osteoarthritis to predict their pain and function after surgery. In the first step, the key questions were identified by statistical modelling in a data set of 375 patients undergoing THR. Based on multiple regression, we identified the two most predictive WOMAC questions for pain and the three most predictive WOMAC questions for functional outcome, while controlling for comorbidity, body mass index, age, gender and specific comorbidities relevant to the outcome. In the second step, a pilot study was performed to validate the resulting tool against the full WOMAC questionnaire among 108 patients undergoing THR. The mean difference between observed (WOMAC) and model-predicted value was −1.1 points (95% confidence interval, CI −3.8, 1.5) for pain and −2.5 points (95% CI −5.3, 0.3) for function. The model-predicted value was within 20% of the observed value in 48% of cases for pain and in 57% of cases for function. The tool demonstrated moderate validity, but performed weakly for patients with extreme levels of pain and extreme functional limitations at 3 months post surgery. This may have been partly due to early complications after surgery. However, the outcome-prediction tool may be useful in helping patients to become better informed about the realistic outcome of their THR.

Abstract
UNLABELLED In this study of acute hip fracture patients, we show that hip fracture rates differ by gender between community-dwelling seniors and seniors residing in nursing homes. While women have a significantly higher rate of hip fracture among the community-dwelling seniors, men have a significantly higher rate among nursing home residents. INTRODUCTION Differences in gender-specific hip fracture risk between community-dwelling and institutionalized seniors have not been well established, and seasonality of hip fracture risk has been controversial. METHODS We analyzed detailed data from 1,084 hip fracture patients age 65 years and older admitted to one large hospital center in Zurich, Switzerland. In a sensitivity analysis, we extend to de-personalized data from 1,265 hip fracture patients from the other two large hospital centers in Zurich within the same time frame (total n = 2,349). The denominators were person-times accumulated by the Zurich population in the corresponding age/gender/type of dwelling stratum in each calendar season for the period of the study. RESULTS In the primary analysis of 1,084 hip fracture patients (mean age 85.1 years; 78% women): Among community-dwelling seniors, the risk of hip fracture was twofold higher among women compared with men (RR = 2.16; 95% CI, 1.74-2.69) independent of age, season, number of comorbidities, and cognitive function; among institutionalized seniors, the risk of hip fracture was 26% lower among women compared with men (RR = 0.77; 95% CI: 0.63-0.95) adjusting for the same confounders. In the sensitivity analysis of 2,349 hip fracture patients (mean age 85.0 years, 76% women), this pattern remained largely unchanged. There is no seasonal swing in hip fracture incidence. CONCLUSION We confirm for seniors living in the community that women have a higher risk of hip fracture than men. However, among institutionalized seniors, men are at higher risk for hip fracture.

Abstract
UNLABELLED Our findings show that only about 20% of seniors receive vitamin D supplementation prior to their index hip fracture or after the event. We further confirm the high prevalence of severe vitamin D deficiency in this population and show that those who receive supplementation have significantly higher 25-hydroxyvitamin D (25(OH)D) status. INTRODUCTION The aim of this study is to assess current practice in pre- and post-hip fracture care practice with respect to vitamin D supplementation. METHODS We surveyed 1,090 acute hip fracture patients age 65 and older admitted to acute care for hip fracture repair; 844 had serum 25-hydroxyvitamin D levels measured upon admission to acute care, and 362 agreed to be followed at 12 month after their hip fracture. Prevalence of vitamin D supplementation was assessed upon admission to acute care (at the time of hip fracture), upon discharge from acute care, and at 6 and 12 months follow-up. RESULTS Of 1,090 acute hip fracture patients (mean age 85 years, 78% women, 59 % community-dwelling), 19% had received any dose of vitamin D prior to the index hip fracture, 27% (of 854 assessed) at discharge from acute care, 22 % (of 321 assessed) at 6 month, and 21% (of 285 assessed) at 12 month after their hip fracture. At the time of fracture, 45% had 25(OH)D levels below 10 ng/ml, 81% had levels below 20 ng/ml, and 96% had levels below 30 ng/ml. Notably, 25(OH)D levels did not differ by season or gender but were significantly higher among 164 hip fracture patients, with any vitamin D supplementation compared with 680 without supplementation (19.9 versus 10.8 ng/ml; p < 0.0001). CONCLUSION Only about 20% of seniors receive vitamin D at the time of their fracture and after the event. This is despite the documented 81% prevalence of vitamin D deficiency. Interdisciplinary efforts may be warranted to improve vitamin D supplementation in seniors both before a hip fracture occurs and after.

Abstract
BACKGROUND Inactive individuals face motivational obstacles for becoming and remaining physically active. Therefore, sustainable physical activity promotion programmes tailored to reach inactive individuals are needed. The aim of this study was to test the role of motivation and the effect and feasibility of a training programme. METHODS We enrolled physically inactive female hospital staff members aged 45 and older in an uncontrolled exercise trial. Follow-up assessments were at 3 and 12 months. The primary outcome was running distance (Cooper test). Secondary outcomes were level of physical activity (Freiburger Physical Activity Questionnaire) and body mass index. RESULTS Out of 1249 female hospital staff, 275 classified themselves as inactive and 250 (91%) of them were interested in the exercise programme. Of these, 68 (27%; mean age 53.2 years) agreed to participate in our study and 47 (69%) completed the programme. Average running distance increased by 255.70 m [95% confidence interval (CI) 208.09-303.31] at 3-month follow-up with a sustained benefit at 12-month follow-up (194.02; 95% CI 143.75-244.47). Physical activity level increased by 1152.52 kcal week(-1) (95% CI 703.73-1601.32) at 3 months with a sustained benefit (1279.10 kcal week(-1), 95% CI 826.80-1731.40) after 12 months. Notably, baseline motivation to become physically active was not associated with change in physical performance or physical activity level during the programme. CONCLUSION The 3-month step-up jogging programme is a feasible and effective exercise intervention for physically inactive, middle-aged female hospital staff members. The intervention leads to sustained benefits independently of motivation to become more physically active.

Abstract
BACKGROUND It is not well established if and to what extent mild to moderate cognitive impairment predicts mortality and risk of nursing home admission after hip fracture. OBJECTIVE To investigate prospectively whether and to what extent mild to moderate cognitive impairment, contributes to mortality and admission to nursing home in the first year after acute hip fracture. METHODS We enrolled 173 patients with acute hip fracture age 65 and older who reached a Mini-Mental State Examination (MMSE) score of at least 15 during acute care after hip fracture repair. An MMSE score of 15 to 24 (median) was classified as mild to moderate cognitive impairment. Primary outcomes were mortality in all and admission to nursing home among seniors who lived at home prior to their hip fracture. Follow-up was 12 months with clinical visits at baseline, 6, and 12 months, plus monthly phone calls. We used Cox proportional hazards models controlling for age, sex, body mass index, baseline number of comorbidities and 25-hydroxyvitamin D status, and severe incident infections to assess the risk of mortality and nursing home admission. Because the study population was enrolled in a factorial design clinical trial testing high dose vitamin D and/or an exercise home program, all analyses also controlled for these treatment strategies. RESULTS Of 173 acute hip fracture patients enrolled, 79% were women, 77% were admitted from home, and 80% were vitamin D deficient (<20ng/ml). Mean age was 84 years. 54% had mild to moderate cognitive impairment. Over the 12-month follow-up, 20 patients died (27% of 173) and 47 (35% of 134) were newly admitted to a nursing home. Mild to moderate cognitive impairment was associated with a more than 5-fold increased risk of mortality (HR=5.77; 95% CI: 1.55-21.55) and a more than 7-fold increased risk of nursing home admission (HR=7.37; 95% CI: 1.75-30.95). Additional independent risk factors of mortality were male gender (HR=3.55; 95% CI: 1.26-9.97), low BMI (HR=7.25; 95% CI: 1.61-33.74), and baseline 25-hydroxyvitamin D level (per 1ng/ml: HR=0.93; 95% CI: 0.87-0.998; p=0.04). CONCLUSIONS Mild to moderate cognitive impairment in patients with acute hip fracture is associated with a high risk of mortality and nursing home admission during the first year after hip fracture. Female gender, a greater BMI and a higher 25-hydroxyvitamin D status may protect against mortality after hip fracture independent of cognitive function.

Abstract
To test the effect of 25(OH)D(3) (HyD) compared to vitamin D(3) on serum 25-hydroxyvitamin D levels (25(OH)D), lower extremity function, blood pressure, and markers of innate immunity. Twenty healthy postmenopausal women with an average 25(OH)D level of 13.2 ± 3.9 ng/mL (mean ± SD) and a mean age of 61.5 ± 7.2 years were randomized to either 20 µg of HyD or 20 µg (800 IU) of vitamin D(3) per day in a double-blind manner. We measured on 14 visits over 4 months, 25(OH)D serum levels, blood pressure, and seven markers of innate immunity (eotaxin, interleukin [IL]-8, IL-12, interferon gamma-induced protein 10 kDa [IP-10], monocyte chemotactic protein-1 [MCP-1], macrophage inflammatory protein beta [MIP-1β], and "Regulated upon Activation, Normal T-cell Expressed, and Secreted" [RANTES]). At baseline and at 4 months, a test battery for lower extremity function (knee extensor and flexor strength, timed up and go, repeated sit-to-stand) was assessed. All analyses were adjusted for baseline measurement, age, and body mass index. Mean 25(OH)D levels increased to 69.5 ng/mL in the HyD group. This rise was immediate and sustained. Mean 25(OH)D levels increased to 31.0 ng/mL with a slow increase in the vitamin D(3) group. Women on HyD compared with vitamin D(3) had a 2.8-fold increased odds of maintained or improved lower extremity function (odds ratio [OR] = 2.79; 95% confidence interval [CI], 1.18-6.58), and a 5.7-mmHg decrease in systolic blood pressure (p = 0.0002). Both types of vitamin D contributed to a decrease in five out of seven markers of innate immunity, significantly more pronounced with HyD for eotaxin, IL-12, MCP-1, and MIP-1 β. There were no cases of hypercalcemia at any time point. Twenty micrograms (20 µg) of HyD per day resulted in a safe, immediate, and sustained increase in 25(OH)D serum levels in all participants, which may explain its significant benefit on lower extremity function, systolic blood pressure, and innate immune response compared with vitamin D(3).

Abstract
In cancer cell lines and rodent models, calcium and vitamin D favorably modulate cell proliferation, differentiation, and apoptosis in colonic epithelia. These effects may be modulated by local expression of the calcium receptor (CaR), the vitamin D receptor (VDR), and the P450 cytochromes, CYP27B1 and CYP24A1; however, they have yet to be investigated in humans. To address this gap, we conducted a randomized, double-blinded, placebo-controlled 2×2 factorial clinical trial. Patients with at least one pathology-confirmed colorectal adenoma were treated with 2 g/d elemental calcium and/or 800 IU/d vitamin D3 versus placebo over 6 months (n=92; 23 per group). CaR, VDR, CYP27B1, and CYP24A1 expression and distribution in biopsies of normal appearing rectal mucosa were detected by standardized, automated immunohistochemistry and quantified by image analysis. In the calcium-supplemented group, CaR expression increased 27% (P=0.03) and CYP24A1 expression decreased 21% (P=0.79). In the vitamin D3-supplemented group, CaR expression increased 39% (P=0.01) and CYP27B1 expression increased 159% (P=0.06). In patients supplemented with both calcium and vitamin D3, VDR expression increased 19% (P=0.13) and CaR expression increased 24% (P=0.05). These results provide mechanistic support for further investigation of calcium and vitamin D3 as chemopreventive agents against colorectal neoplasms, and CaR, VDR, CYP27B1, and CYP24A1 as modifiable, preneoplastic risk biomarkers for colorectal neoplasms.

Abstract
To further clarify and develop calcium and vitamin D as chemopreventive agents against colorectal cancer in humans and develop modifiable biomarkers of risk for colorectal cancer, we conducted a pilot, randomized, double-blind, placebo-controlled, 2 x 2 factorial clinical trial to test the effects of calcium and vitamin D(3), alone and in combination, on key DNA mismatch repair proteins in the normal colorectal mucosa. Ninety-two men and women with at least one pathology-confirmed colorectal adenoma were treated with 2.0 g/d calcium or 800 IU/d vitamin D(3), alone or in combination, versus placebo over 6 months. Colorectal crypt overall expression and distribution of MSH2 and MLH1 proteins in biopsies of normal-appearing rectal mucosa were detected by automated immunohistochemistry and quantified by image analysis. After 6 months of treatment, MSH2 expression along the full lengths of crypts increased by 61% (P = 0.11) and 30% (P = 0.36) in the vitamin D and calcium groups, respectively, relative to the placebo group. The estimated calcium and vitamin D treatment effects were more pronounced in the upper 40% of crypts (differentiation zone) in which MSH2 expression increased by 169% (P = 0.04) and 107% (P = 0.13) in the vitamin D and calcium groups, respectively. These findings suggest that higher calcium and vitamin D intakes may result in increased DNA MMR system activity in the normal colorectal mucosa of sporadic adenoma patients and that the strongest effects may be vitamin D related and in the differentiation zone of the colorectal crypt.

Abstract
The exact antineoplastic effects of calcium and vitamin D(3) in the human colon are unclear. Animal and in vitro studies show that these two agents reduce oxidative stress; however, these findings have never been investigated in humans. To address this, we conducted a pilot, randomized, double-blind, placebo-controlled, 2 x 2 factorial clinical trial to test the effects of calcium and vitamin D(3) on a marker of oxidative DNA damage, 8-hydroxy-2'-deoxyguanosine (8-OH-dG), in the normal colorectal mucosa. Patients (N = 92) with at least one pathology-confirmed colorectal adenoma were treated with 2 g/d calcium and/or 800 IU/d vitamin D(3) versus placebo over 6 months. Overall labeling and colorectal crypt distribution of 8-OH-dG in biopsies of normal-appearing rectal mucosa were detected by standardized automated immunohistochemistry and quantified by image analysis. After 6 months of treatment, 8-OH-dG labeling along the full lengths of colorectal crypts decreased by 22% (P = 0.15) and 25% (P = 0.10) in the calcium and vitamin D(3) groups, respectively, but not in the calcium plus vitamin D(3) group. The estimated treatment effects were strongest among participants with higher baseline colon crypt vitamin D receptor expression (P = 0.05). Overall, these preliminary results indicate that calcium and vitamin D(3) may decrease oxidative DNA damage in the normal human colorectal mucosa, support the hypothesis that 8-OH-dG labeling in colorectal crypts is a treatable oxidative DNA damage biomarker of risk for colorectal neoplasms, and provide support for further investigation of calcium and vitamin D(3) as chemopreventive agents against colorectal neoplasms.

Abstract
To investigate the potential efficacy of calcium and vitamin D in reducing risk for colorectal neoplasms and to develop "treatable" phenotypic biomarkers of risk for colorectal neoplasms, we conducted a pilot, randomized, double-blind, placebo-controlled, 2 x 2 factorial clinical trial to test the effects of these agents on cell cycle markers in the normal colorectal mucosa. Ninety-two men and women with at least one pathology-confirmed colorectal adenoma were treated with 2 g/day calcium and/or 800 IU/day vitamin D(3) versus placebo over 6 months. Overall expression and distributions of p21(waf1/cip1) (marker of differentiation), MIB-1 (marker of short-term proliferation), and hTERT (marker of long-term proliferation) in colorectal crypts in the normal-appearing rectal mucosa were detected by automated immunohistochemistry and quantified by image analysis. In the calcium, vitamin D, and calcium plus vitamin D groups relative to the placebo, p21 expression increased by 201% (P = 0.03), 242% (P = 0.005), and 25% (P = 0.47), respectively, along the full lengths of colorectal crypts after 6 months of treatment. There were no statistically significant changes in the expression of either MIB-1 or hTERT in the crypts overall; however, the proportion of hTERT, but not MIB-1, expression that extended into the upper 40% of the crypts was reduced by 15% (P = 0.02) in the vitamin D plus calcium group relative to the placebo. These results indicate that calcium and vitamin D promote colorectal epithelial cell differentiation and may "normalize" the colorectal crypt proliferative zone in sporadic adenoma patients, and support further investigation of calcium and vitamin D as chemopreventive agents against colorectal neoplasms.

Abstract
To characterize the expression of the mismatch repair gene MSH2 in normal colorectal crypts in humans and assess parameters of its expression as a potential modifiable biomarker of risk for colorectal neoplasms, we conducted a pilot, colonoscopy-based case-control study (51 cases and 154 controls) of incident, sporadic colorectal adenoma. Biopsies of normal-appearing rectal, sigmoid, and ascending colon mucosa were procured, immunohistochemically processed for MSH2 protein, and analyzed using custom quantitative image analysis procedures. MSH2 expression in adenoma cases was lower than in controls by 49% (P = 0.01) and 23% (P = 0.06) in the ascending colon and rectum, respectively, but not in the sigmoid colon. MSH2 expression in the rectum was 39% (P = 0.04) higher in subjects who regularly took a nonsteroidal anti-inflammatory drug than in those who did not, and it tended to be lower in those with adenomas in the right colon and those who had an adenoma with more advanced characteristics. These preliminary data suggest that lower MSH2 expression in the normal colonic mucosa, at least in the ascending colon and rectum, may be associated with increased risk of incident, sporadic colorectal adenoma as well as with modifiable risk factors for colorectal neoplasms, thus supporting further investigation of MSH2 expression as a potential modifiable biomarker of risk for colorectal neoplasms.

Abstract
To characterize the expression of the mismatch repair gene MutL-homolog 1 (MLH1) in normal colorectal crypts in humans, and assess parameters of its expression as a potential biomarker of risk for colorectal neoplasms, we conducted a pilot, colonoscopy-based case-control study (51 cases, 154 controls) of incident, sporadic colorectal adenoma. Biopsies of normal-appearing rectal, sigmoid, and ascending colon mucosa were procured, immunohistochemically processed for MLH1 protein, and analyzed using custom quantitative image analysis procedures. MLH1 expression in the ascending colon was, on average, 49% proportionally lower in cases than controls (P = 0.03), but there was little evidence for case-control differences in the rectum and sigmoid colon. In cases and controls, average MLH1 expression in the ascending colon tended to be lower with increased age [by 56% (P = 0.02) and 25% (P = 0.16), respectively, for those > or =55 years], and with a history of colorectal cancer in a first-degree relative (by 22% [P = 0.56] and 34% [P = 0.16], respectively). Among cases, but not controls, average MLH1 expression tended to be higher with current alcohol consumption, regular aspirin use, and higher total intakes of calcium, vitamin D, and folate. There was little indication of similar differences in the rectum. These preliminary data suggest that lower MLH1 expression in the normal colonic mucosa, at least in the ascending colon, may be associated with increased risk of incident, sporadic colorectal adenoma, as well as with modifiable risk factors for colorectal neoplasms, thus supporting further investigation of MLH1 expression as a potential "treatable" biomarker of risk for colorectal neoplasms.

Abstract
BACKGROUND Transforming growth factor-alpha (TGF-alpha), a stimulatory growth factor and member of the epidermal growth factor family, is a mediator of oncogenesis and malignant progression in colorectal carcinogenesis. Limited evidence suggests its utility as a growth-related biomarker of risk for colorectal cancer. METHODS We measured expression of TGF-alpha in biopsies of normal-appearing colorectal mucosa using automated immunohistochemistry and quantitative image analysis in a subsample of 29 cases and 31 controls from a colonoscopy-based case-control study (n = 203) of biomarkers of risk for incident sporadic colorectal adenoma. Diet, lifestyle, and medical history were assessed with validated questionnaires. RESULTS TGF-alpha expression in the rectum was 51% higher in cases compared with controls (P = 0.05) and statistically significantly associated with accepted risk factors for colorectal neoplasms (36% lower among nonsteroidal anti-inflammatory drug users, 49% lower among women using hormone replacement therapy, 79% higher among persons with a family history of colorectal cancer). CONCLUSIONS TGF-alpha expression in the normal-appearing rectal mucosa shows promise as an early, potentially modifiable biomarker of risk for colorectal cancer.
