Background: Population-based studies have shown good correlation between severity of atherosclerotic disease in one arterial bed and involvement of other vessels. However, in patients with coronary artery disease (CAD), it remains unclear whether atherosclerotic plaque in an artery might regress or progress in parallel with other vessels. Accordingly, the present study was performed in patients with CAD to compare changes in plaque volume (PV) between the left main (LMT) and right coronary arteries (RCA), thoracic descending aorta (TDA) and common carotid artery (CCA), and to clarify clinical factors and biomarkers which might affect changes in PV in each artery. Methods: Using 64-multislice computed tomography, PVs in each artery were determined before and after 2.0-year follow-up period in 52 patients with CAD (67.4±9.9yo). Based on our previous study using ultrasound, CCA-PV was determined at windows of 90–240HU and TDA-PV determined manually. Coronary soft plaque was determined at windows of 0–75HU. Plasma levels of hsCRP, matrix metalloproteinase (MMP)-9 and urinary 8-iso-prostaglandin F2 α (PGF) were determined at baseline. Results: At baseline, PVs of TDA were correlated with CCA-PV (r=0.38, p<0.02), but PVs of other arteries did not correlate to each other. Two-year later, PVs of LMT, RCA, TDA, and CCA were reduced in 41, 62, 27, and 39% of patients, respectively. Changes in LMT-PV were weakly related with those of TDA-PV (r=0.37, p=0.02) and RCA-PV (r=0.31, p=0.08), but there were no relation between other arteries. The multivariate analysis revealed that treatment with statin and low LDL-cholesterol (C, <100mg/dl) were independent variables regarding a reduction in DTA-PV, but, in LMT, only low LDL-C was independent variable. However, there were no independent variables in RCA or CCA. The ratio of soft PV to total PV was similar between LMT (45.2±7.1%) and RCA (45.7±4.9%) at baseline and was unchanged in the follow-up study. None of hsCRP, MMP-9 or PGF levels was related with PVs of any arteries at baseline and with changes in PVs. Conclusions: Regression of PV in one arterial bed dose not necessarily allow us to predict atherosclerotic changes in the other vessels. Major factors which affect changes in PV may not be homogeneous between arteries.

ObjectiveTo examine psychotropic and pain medication use in a population-based cohort of individuals with traumatic brain injury (TBI), and compare them with controls from similar backgrounds.MethodsWe assessed Swedish nationwide registers to include all individuals diagnosed with incident TBI between 2006 and 2012 in hospitals or specialist outpatient care. Full siblings never diagnosed with TBI acted as controls. We examined dispensed prescriptions for psychotropic and pain medications for the 12 months before and after the TBI.ResultsWe identified 239 425 individuals with incident TBI, and 199 658 unaffected sibling controls. In the TBI cohort, 36.6% had collected at least one prescription for a psychotropic or pain medication in the 12 months before the TBI. In the 12 months after, medication use increased to 45.0%, an absolute rate increase of 8.4% (p<0.001). The largest post-TBI increases were found for opioids (from 16.3% to 21.6%, p<0.001), and non-opioid pain medications (from 20.3% to 26.6%, p<0.001). The majority of prescriptions were short-term; 20.6% of those prescribed opioids and 37.3% of those with benzodiazepines collected prescriptions for more than 6 months. Increased odds of any psychotropic or pain medication were associated with individuals before (OR: 1.62, 95% CI: 1.59 to 1.65), and after the TBI (OR: 2.30, 95% CI: 2.26 to 2.34) as compared with sibling controls, and ORs were consistently increased for all medication classes.ConclusionHigh rates of psychotropic and pain medications after a TBI suggest that medical follow-up should be routine and review medication use.

ObjectiveAlthough knowledge on poststroke cognitive and functional decline is increasing, little is known about the possible decline of these functions before stroke. We determined the long-term trajectories of cognition and daily functioning before and after stroke.MethodsBetween 1990 and 2016, we repeatedly assessed cognition (Mini-Mental State Examination (MMSE), 15-Word Learning, Letter–Digit Substitution, Stroop, Verbal Fluency, Purdue Pegboard) and basic and instrumental activities of daily living (BADL and IADL) in 14 712 participants within the population-based Rotterdam Study. Incident stroke was assessed through continuous monitoring of medical records until 2018. We matched participants with incident stroke to stroke-free participants (1:3) based on sex and birth year. Trajectories of cognition and daily functioning of patients who had a stroke 10 years before and 10 years after stroke and the corresponding trajectories of stroke-free individuals were constructed using adjusted linear mixed effects models.ResultsDuring a mean follow-up of 12.5±6.8 years, a total of 1662 participants suffered a first-ever stroke. Patients who had a stroke deviated from stroke-free controls up to 10 years before stroke diagnosis in cognition and daily functioning. Significant deviations before stroke were seen in scores of MMSE (6.4 years), Stroop (5.7 years), Purdue Pegboard (3.8 years) and BADL and IADL (2.2 and 3.0 years, respectively).ConclusionPatients who had a stroke have steeper declines in cognition and daily functioning up to 10 years before their first-ever stroke compared with stroke-free individuals. Our findings suggest that accumulating intracerebral pathology already has a clinical impact before stroke.

ObjectiveTo prospectively validate the CT-Valve score, a new risk score designed to identify patients with valvular heart disease at a low risk of coronary artery disease (CAD) who could benefit from multislice CT (MSCT) first instead of coronary angiography (CAG).MethodsThis was a prospective cohort study of patients referred for valve surgery in the Capital Region of Denmark and Odense University Hospital from the 1 February 2015 to the 1 February 2017. MSCT was implemented for patients with a CT-Valve score ≤7 at the referring physician’s discretion. Patients with a history of CAD or chronic kidney disease were excluded. The primary outcome was the proportion of patients needing reevaluation with CAG after MSCT and risk of CAD among the patients determined to be low to intermediate risk.ResultsIn total, 1149 patients were included. The median score was 9 (IQR 3) and 339 (30%) had a score ≤7. MSCT was used for 117 patients. Of these 29 (25%) were reevaluated and 9 (7.7%) had CAD. Of the 222 patients with a score ≤7 that did not receive an MSCT, 14 (6%) had significant CAD. The estimated total cost of evaluation among patients with a score ≤7 before implementation was €132 093 compared with €79 073 after, a 40% reduction. Similarly, estimated total radiation before and after was 608 mSv and 362 mSv, a 41% reduction. Follow-up at a median of 32 months (18–48) showed no ischaemic events for patients receiving only MSCT.ConclusionThe CT-Valve score is a valid method for determining risk of CAD among patients with valvular heart disease. Using a score ≤7 as a cut-off for the use of MSCT is safe and cost-effective.

Abstract Context Fracture-on-therapy should motivate better anti-fracture medication adherence. Objective Describe osteoporosis medication adherence in women before and following a fracture. Design Retrospective cohort study. Setting Manitoba BMD Registry (1996-2013). Patients Women who started anti-fracture drug therapy after a DXA-BMD with follow-up for 5 years during which a non-traumatic fracture occurred at least one year after starting treatment. Main Outcome Linked prescription records determined medication adherence (estimated by medication possession ratios, MPR) in one-year intervals. The variable of interest was MPR in the year before and after the year in which the fracture occurred with subgroup analyses according to duration of treatment pre-fracture. We chose an MPR of ≥0.50 to indicate minimum adherence needed for drug efficacy. Results There were 585 women with fracture-on-therapy, 193(33%) had hip or vertebral fracture. Bisphosphonates accounted for 82.2% of therapies. Median MPR the year prior to fracture was 0.89(IQR 0.49-1.0) and 0.69(IQR 0.07-0.96) the year following the year of fracture(p&lt; 0.0001). The percentage of women with MPR ≥ 0.5 pre-fracture was 73.8%, dropping to 57.3% post-fracture(p&lt;0.0001); restricted to hip/vertebral fracture results were similar (58.2% to 33.3%, p &lt;0.002). Among those with pre-fracture MPR &lt;0.5, only 21.7% achieved a post-fracture MPR ≥ 0.5. Conclusions Although fracture-on-therapy may motivate sustained/improved adherence, MPR remains low or even declines after fracture in many. This could reflect natural decline in MPR with time but is paradoxical to expectations. Fracture-on-therapy represents an important opportunity for clinicians to re-emphasize treatment adherence.

ObjectiveOur objective was to investigate individual serum thyroglobulin (Tg) changes in relation to iodine fortification (IF) and to clarify possible predictors of these changes.DesignWe performed a longitudinal population-based study (DanThyr) in two regions with different iodine intake at baseline: Aalborg (moderate iodine deficiency (ID)) and Copenhagen (mild ID). Participants were examined at baseline (1997) before the mandatory IF of salt (2000) and again at follow-up (2008) after IF.MethodsWe examined 2465 adults and a total of 1417 participants with no previous thyroid disease and without Tg-autoantibodies were included in the analyses. Serum Tg was measured by immunoradiometric method. We registered participants with a daily intake of iodine from supplements in addition to IF.ResultsOverall, the follow-up period saw no change in median Tg in Copenhagen (9.1/9.1 μg/l,P=0.67) while Tg decreased significantly in Aalborg (11.4/9.0 μg/l,P<0.001). Regional differences were evident before IF (Copenhagen/Aalborg, 9.1/11.4 μg/l,P<0.001), whereas no differences existed after IF (9.1/9.0 μg/l,P=1.00). Living in Aalborg (P<0.001) and not using iodine supplements at baseline (P=0.001) predicted a decrease in Tg whereas baseline thyroid enlargement (P=0.02) and multinodularity (P=0.01) were associated with an individual increase in Tg during follow-up.ConclusionsAfter IF we observed a decrease in median Tg in Aalborg and the previously observed regional differences between Aalborg and Copenhagen had levelled out. Likewise, living in Aalborg was a strong predictor of an individual decrease in serum Tg. Thus, even small differences in iodine intake at baseline were very important for the individual response to IF.

Endometriosis (EM) with chronic inflammation may accelerate the progression of atherosclerosis. Currently, no large or randomized clinical studies have assessed the incidence of cardiovascular events in patients with endometriosis in Asia to investigate whether incident EM is associated with a higher risk of new-onset coronary artery disease (CAD). In this study of a nationwide cohort in Taiwan, we identified 13,988 patients with newly diagnosed EM from 1 January, 2000, through 31 December, 2012. EM and non-EM groups were matched by propensity score at a ratio of 1:1. Of a total 27,976 participants, 358 developed CAD. The incidence rate in the EM group was higher than that in the non-EM group (1.8 per 1,000 person-years vs. 1.3 per 1,000 person-years) during the follow-up period. The adjusted hazard ratio (aHR) of CAD for the EM group was 1.52 with a 95% confidence interval (1.23–1.87, p &lt; 0.001) after adjusting for demographic characteristics, comorbidities, surgical procedures, frequency of outpatient visits, and medications. Stratified analysis revealed that, among four age groups (20–39, 40–49, 50–54, and above 55 years), the 20–39 years sub-group was associated with a higher risk of CAD (aHR, 1.73; 95% CI, 1.16–2.59, p = 0.008). Several sensitivity analyses were conducted for cross-validation, and it showed consistent positive findings. In conclusion, this cohort study revealed that patients with symptomatic EM in Taiwan were associated with increased risk of subsequent CAD than patients without medical records of EM. Further prospective studies are needed to confirm this causal relationship.

Background: Previous research in our population showed a steeper long-term decline in functional status after first ischemic stroke among those with Medicaid or no insurance compared to those with Medicare or private insurance. With only post-stroke data, it was unknown whether these findings were caused by the stroke. We sought to compare the long-term trajectory of functional status before and after ischemic stroke. Methods: The Northern Manhattan Study contains a prospective, population-based study of stroke-free individuals >40 years of age, followed for a median of 10 years. The Barthel index (BI) was assessed annually. Generalized estimating equations were used to assess functional decline over time before and after stroke. The 6 months after stroke were ignored, since the course of recovery during this period is well documented, and our interest was the long-term course of functional status. Follow-up was censored at the time of recurrent stroke. Sociodemographic and medical risk factors were included and results were stratified by insurance status. Linearity of the curves was evaluated by plotting residuals against time and with a lowess curve. Results: Among 3298 participants, 261 had an ischemic stroke during follow-up, of which 51 died within 6 months of stroke. Among the remaining 210 participants, mean age at stroke (standard deviation) was 77+9 years, 38% were male, 52% were Hispanic, 37% had diabetes, and 31% had coronary artery disease. There was no difference in functional decline over time before and after stroke (p= 0.51), with a decline of 0.96 BI points per year before stroke (p<.0001) and 1.24 after stroke (p=0.001). However, when stratified by insurance status, among those with Medicaid or no insurance, in a fully adjusted model, there was a difference in slope before and after stroke (p=0.04), with a decline of 0.58 BI points per year before stroke (p=0.02) and 1.94 after stroke (p=0.001). Other predictors of worse functional status were increasing age, female sex, diabetes, and being married. Conclusion: In this large, prospective, population-based study with long-term follow-up, there was a significantly steeper decline in functional status after ischemic stroke compared to before stroke among those with Medicaid or no insurance, after adjusting for confounders. The cause of this differential decline is not known but may be related to poor control of risk factors, silent strokes, or an effect of socioeconomic status.

ObjectiveChildbirth is suggested to be associated with elevated levels of sickness absence (SA) and disability pension (DP). However, detailed knowledge about SA/DP patterns around childbirth is lacking. We aimed to compare SA/DP across different time periods among women according to their childbirth status.DesignRegister-based longitudinal cohort study.SettingSweden.ParticipantsThree population-based cohorts of nulliparous women aged 18–39 years, living in Sweden 31 December 1994, 1999 or 2004 (nearly 500 000/cohort).Primary and secondary outcome measuresSum of SA >14 and DP net days/year.MethodsWe compared crude and standardised mean SA and DP days/year during the 3 years preceding and the 3 years after first childbirth date (Y−3to Y+3), among women having (1) their first and only birth during the subsequent 3 years (B1), (2) their first birth and at least another delivery (B1+), and (3) no childbirths during follow-up (B0).ResultsDespite an increase in SA in the year preceding the first childbirth, women in the B1 group, and especially in B1+, tended to have fewer SA/DP days throughout the years than women in the B0 group. For cohort 2005, the mean SA/DP days/year (95% CIs) in the B0, B1 and B1+ groups were for Y−3: 25.3 (24.9–25.7), 14.5 (13.6–15.5) and 8.5 (7.9–9.2); Y−2: 27.5 (27.1–27.9), 16.6 (15.5–17.6) and 9.6 (8.9–10.4); Y−1: 29.2 (28.8–29.6), 31.4 (30.2–32.6) and 22.0 (21.2–22.9); Y+1: 30.2 (29.8–30.7), 11.2 (10.4–12.1) and 5.5 (5.0–6.1); Y+2: 31.7 (31.3–32.1), 15.3 (14.2–16.3) and 10.9 (10.3–11.6); Y+3: 32.3 (31.9–32.7), 18.1 (17.0–19.3) and 12.4 (11.7–13.0), respectively. These patterns were the same in all three cohorts.ConclusionsWomen with more than one childbirth had fewer SA/DP days/year compared with women with one childbirth or with no births. Women who did not give birth had markedly more DP days than those giving birth, suggesting a health selection into childbirth.
