This study investigated 12-year blood lipid trajectories and whether these trajectories are modified by smoking and lipid lowering treatment in older Russians. To do so, we analysed data on 9,218 Russian West-Siberian Caucasians aged 45–69 years at baseline participating in the international HAPIEE cohort study. Mixed-effect multilevel models were used to estimate individual level lipid trajectories across the baseline and two follow-up examinations (16,445 separate measurements over 12 years). In all age groups, we observed a reduction in serum total cholesterol (TC), LDL-C and non-HDL-C over time even after adjusting for sex, statin treatment, hypertension, diabetes, social factors and mortality (P<0.01). In contrast, serum triglyceride (TG) values increased over time in younger age groups, reached a plateau and decreased in older age groups (> 60 years at baseline). In smokers, TC, LDL-C, non-HDL-C and TG decreased less markedly than in non-smokers, while HDL-C decreased more rapidly while the LDL-C/HDL-C ratio increased. In subjects treated with lipid-lowering drugs, TC, LDL-C and non-HDL-C decreased more markedly and HDL-C less markedly than in untreated subjects while TG and LDL-C/HDL-C remained stable or increased in treatment naïve subjects. We conclude, that in this ageing population we observed marked changes in blood lipids over a 12 year follow up, with decreasing trajectories of TC, LDL-C and non-HDL-C and mixed trajectories of TG. The findings suggest that monitoring of age-related trajectories in blood lipids may improve prediction of CVD risk beyond single measurements.

Abstract Background: Few studies have been conducted to investigate the association of kidney function decline with the trajectories of homocysteine (Hcy) over time, using repeated measurements. We aimed to investigate the association of kidney function with changes in plasma Hcy levels over time. Methods: Data were collected from the Rugao Longevity and Ageing Study. In detail, plasma Hcy and creatinine levels were measured in both waves (waves 2, 3 and 4) during the 3.5-year follow-up (N = 1135). Wave 2 was regarded as the baseline survey. The estimated glomerular filtration rate (eGFR) was calculated based on creatinine. Subjects were categorized into four groups according to quartiles of eGFR at baseline. Linear mixed-effect models were used to investigate the association of eGFR with subsequent plasma Hcy levels. Results: The mean eGFR at baseline was 90.84 (11.42) mL/min/1.73 m2. The mean plasma Hcy level was 14.09 (6.82) at baseline and increased to 16.28 (8.27) and 17.36 (10.39) μmol/L during follow-ups. In the crude model, the interaction between time and eGFR at baseline was significant (β = −0.02, 95% CI: −0.02 to −0.01, p = 0.002). After adjusting for confounding factors, a significant relationship remained (β = −0.02, 95% CI: −0.02 to −0.01, p = 0.003), suggesting that kidney function decline at baseline was associated with a faster increase in Hcy levels. Conclusion: Kidney function decline is associated with a more pronounced increase in plasma Hcy levels. Further studies with longer follow-up periods and larger sample sizes are needed to validate our findings.

AbstractBackground:Cochlear implantation is the standard of care for treating severe to profound hearing loss in all age groups. There is limited data on long-term results in elderly implantees and the effect of ageing on outcomes. This study compared the stability of cochlear implantation outcome in elderly and younger patients.Methods:A retrospective chart review of cochlear implant patients with a minimum follow up of five years was conducted.Results:The study included 87 patients with a mean follow up of 6.8 years. Of these, 22 patients were older than 70 years at the time of implantation. Hearing in Noise Test scores at one year after implantation were worse in the elderly: 85.3 (aged under 61 years), 80.5 (61–70 years) and 73.6 (aged over 70 years;p= 0.039). The respective scores at the last follow up were 84.8, 85.1 and 76.5 (p= 0.054). Most patients had a stable outcome during follow up. Of the elderly patients, 13.6 per cent improved and none had a reduction in score of more than 20 per cent. Similar to younger patients, elderly patients had improved Short Form 36 Health Survey scores during follow up.Conclusion:Cochlear implantation improves both audiometric outcome and quality of life in elderly patients. These benefits are stable over time.

Abstract Background Blood lipid increases during gestation are considered a physiological adaption, and decrease after delivery. However, some adverse pregnancy outcomes are thought to be related to gestational lipid levels. Therefore, it is necessary to have a reference range for lipid changes during gestation. The present study aims to describe triglyceride (TG) changes during pregnancy and 42 days postpartum and to find cut-off points for TG levels during the first, second, and third trimesters. Methods A total of 908 pregnant women were followed from recruitment to 42 days postpartum, and their serum lipids were collected at gestational weeks 6–8, 16, 24, and 36 and 42 days postpartum. The major outcome was postpartum hypertriglyceridemia. The association between gestational and postpartum TG levels was analysed by stepwise multiple linear regression. A two-stage approach including a linear mixed-effect model and linear or logistic regression was conducted to explore the contribution of the changes in TG over time in pregnancy to postpartum hypertriglyceridemia. Logistic regression was constructed to examine the association between gestational TG levels and postpartum hypertriglyceridemia. Cut-off points were calculated by receiver operating characteristic (ROC) curves. Results There was a tendency for serum TG to increase with gestational age and decrease at 42 days postpartum. Prepregnancy overweight, obesity, and GDM intensified this elevation. Higher TG levels at gestational weeks 6–8, 16, 24, and 36 were positively associated with a higher risk of postpartum hypertriglyceridemia [OR 4.962, 95 % CI (3.007–8.189); OR 2.076, 95 % CI (1.303–3.309); OR 1.563, 95 % CI (1.092–2.236); and OR 1.534, 95 % CI (1.208–1.946), respectively]. The trend of the change in TG over time was positively associated with the TG level and risk of postpartum hypertriglyceridemia [OR 11.660, 95 % CI (6.018–22.591)]. Based on ROC curves, the cut-off points of serum TG levels were 1.93, 2.35, and 3.08 mmol/L at gestational weeks 16, 24, and 36, respectively. Stratified analysis of prepregnancy body mass index (pre-BMI) and GDM showed that higher gestational TG was a risk factor for postpartum hypertriglyceridemia in women with normal pre-BMI and without GDM. Conclusions Gestational TG and its elevation were risk and predictive factors of postpartum hypertriglyceridemia, especially in pregnant women with normal pre-BMI or without GDM.

Abstract BANKGROUND: Mortality from coronary artery disease continues to rise, and secondary prevention and treatment are particularly important. OBJECTIVE: The objective of this study is to evaluate low-density lipoprotein cholesterol (LDL-C) levels in patients after percutaneous coronary intervention (PCI), to describe how treatment outcomes for individual patients changed over time and to examine the potential impact of lipid control rates through population LDL-C levels changes.METHODS: This retrospective study was conducted in patients who underwent PCI between July 2017 and June 2019. The main results included LDL-C levels after PCI. To assess the outcome of prevention, three separate measures of LDL-C were considered: baseline, first follow-up, and final follow-up, and LDL-C control rates were analyzed according to different guidelines. we examine the impact of 0.1mmol/l decreases or increases in population LDL-C levels on LDL-C control.RESULTS: Data were analyzed for 423 patients (mean age, 62 ±10 years), and the baseline LDL-C level was 3.11 ± 0.99 mmol/l. 51.5% of the patients achieved the Chinese Lipids Guidelines treatment goal, 22% and 11.6% of the patients achieved the 2016 ESC Lipids Guidelines and 2019 ESC Lipids Guidelines treatment goal at the final follow-up period respectively. LDL-C levels fluctuated during the follow-up period, and the long-term maintenance results could not be guaranteed after PCI. Population LDL-C levels changes in lifestyle could have a very large impact on LDL-C control in China.CONCLUSION: LDL-C control with statins is not ideal in patients after PCI, which is far from the requirements of the latest guidelines. Although clinicians understand the lipid-lowering effect of statins, they should not give up active lifestyle changes, and should strengthen the comprehensive management of blood lipid control.

Abstract Background A recent systematic review highlighted significant gaps in the evidence on atrial fibrillation (AF) patients' adherence to oral anticoagulants (OAC). Current evidence suffers from short follow-up times, focuses on the first OAC and does not take switching into account. There is also lack of observational data on adherence to warfarin due to its varying dose that complicates the calculations. As such there is lack of evidence on comparative adherence between VKAs and DOACs and whether the convenience of DOACs translates into better adherence in AF patients. Purpose Our objective was to measure AF patients' long-term OAC adherence and compare the impact of taking direct oral anticoagulants (DOAC) versus vitamin K antagonists (VKA) on adherence, while accounting for switching. Methods Using linked, population-based administrative data containing physician billings, hospitalization and prescription records of 4.8 million British Columbians (1996–2019), incident adult cases of AF were identified. The primary measure of adherence was proportion of days covered (PDC). Consecutive rolling 90-day windows were created for each patient starting from their first OAC prescription fill date until the end of their follow-up. The PDC for each 90-day rolling window was calculated and averaged to yield mean adherence over the follow-up period for each patient. Permanent medication discontinuation resulted in a PDC of 0 for all subsequent rolling windows after their supply ran out. As such, both poor execution and non-persistence were measured simultaneously. The association between drug class and adherence was assessed using generalized mixed effect linear regression models with drug class treated as time-varying covariate to account for switching. Results The study cohort was 30,264 AF patients [mean age 72.2 years (SD11.0), 44.6% female, mean CHA2DS2-VASc 2.94 (SD1.4)] with mean follow-up of 7.7 (SD 4.8) years. The mean PDC was 0.71 (SD 0.27) with 51% of the cohort having mean PDC values below the conventional threshold of adherence (PDC&lt;0.8). Adherence dropped over time with the greatest decline in the first two years after therapy initiation. After controlling for all other confounders and accounting for switching, taking VKA compared to DOAC was, on average, associated with a 1-day decrease in number of days of medication-taking per year. Conclusion AF patients' OAC adherence was below the conventional threshold of 0.8, and dropped over time, particularly in the first two years. Drug class had no clinically meaningful impact on medication adherence. Our study highlights the need for effective adherence interventions particularly early in OAC therapy. Our findings also emphasizes that prescribers should not assume inherently better adherence for DOACs and should instead choose OAC in conversation with the patient and in accordance with their values and preferences.

This study was designed to investigate the natural history of atlantoaxial instability in individuals with Down syndrome and to determine whether significant changes in C1-C2 relationship are taking place over time. Although more than 400 patients with Down syndrome who are presently followed at the Child Development Center had cervical spine radiographic examinations in the past, only 141 patients who had serial radiological examinations and whose radiographs were available for reevaluation participated in this study. The results of our investigations revealed that there were only minor changes (1 to 1.5 mm) of atlanto-dens interval measurements over time in 130 (92%) patients with Down syndrome. Eleven patients (8%) had changes of atlanto-dens interval measurements between 2 and 4 mm over time; however, none of these patients had any clinical symptoms. The analyses of data obtained from several subgroups (males and females, various age groups, and patients with and without atlantoaxial instability) did not show any significant changes of atlanto-dens interval measurements of successively obtained radiographs. Our recommendations for and rationale of routine screening for atlantoaxial instability and follow-up examinations are discussed in detail.

AbstractEmerging evidence suggests that the consumption of ultra-processed foods (UPF) plays a role in the development of chronic diseases, but evidence of their influence in children is limited. Our objective was to study longitudinal trends of UPF intake and determine their impact on blood lipids in young children. The present study was a follow-up of a randomised field trial of children (n 308) from Porto Alegre, Brazil. Dietary intake was collected using two 24-h recalls at 3 and 6 years of age, and consumption of UPF was classified according to the NOVA system, a food classification based on the extent and purpose of industrial food processing. At age 6 years, blood tests were performed to measure lipid profile. Contribution of UPF to total energy intake increased by 10 % during the follow-up period, from 43·4 % at 3 years to 47·7 % at 6 years of age. Linear regression models showed that children in the highest tertile of UPF consumption at age 3 years had higher levels of total cholesterol (TC; β 0·22 mmol/l; 95 % CI 0·04, 0·39) and TAG at age 6 years (β 0·11 mmol/l, 95 % CI 0·01, 0·20) compared with those in the lowest tertile. A positive dose–response was observed for an absolute increment of 10 % of UPF on TC (β 0·07 mmol/l, 95 % CI 0·00, 0·14) and TAG (β 0·04 mmol/l, 95 % CI 0·01, 0·07). Based on our data, consumption of UPF increased significantly over time and was associated with higher blood lipid levels in children from a low-income community. Our findings highlight the need for effective strategies to minimise the consumption of UPF in early life.

OBJECTIVE <p>Statins may reduce the risk of diabetic polyneuropathy (DPN) due to lipid-lowering and anti-inflammatory effects, but statins have also been associated with neurotoxicity. We examined whether statin therapy impacts the risk of DPN.</p> <p>RESEARCH DESIGN AND METHODS</p> <p>We identified all Danish incident type 2 diabetes patients during 2002-2016. New users initiated statins between 180 days before and 180 days after their first diabetes record, while prevalent users had initiated statins before that period. Patients were followed for incident DPN using validated hospital diagnosis codes, starting 180 days after first diabetes record. Cox proportional hazard analysis was used to compute adjusted hazard ratios (aHRs) for DPN. </p> <p>RESULTS </p> <p>The study cohort comprised 59,255 (23%) new users, 75,528 (29%) prevalent users, and 124,842 (48%) non-users; median follow-up time was 6.2 years (interquartile range 3.4-9.6). The incidence rate of DPN events per 1000 person-years was similar in new users (4.0 [95% CI 3.8-4.2]), prevalent users (3.8 [3.6-3.9]) and non-users (3.8 [3.7-4.0]). The aHR for DPN was 1.05 (0.98-1.11) in new users, and 0.97 (0.91-1.04) in prevalent users, compared with statin non-users. New users had a slightly increased DPN risk during the first year (aHR 1.31 [1.12-1.53]) which vanished after more than 2 years of follow-up. Findings were similar in on-treatment and propensity score-matched analyses, and with additional adjustment for pre-treatment blood lipid levels.</p> <p>CONCLUSION </p> <p>Statin therapy is unlikely to increase or mitigate DPN risk in type 2 diabetes patients, although a small acute risk of harm cannot be excluded.</p>

Background: Children with chronic kidney disease, including those treated with kidney transplantation (KT), have an increased risk of cardiovascular disease. The aim of this study was to examine the cardiopulmonary exercise capacity after KT compared to matched controls, to relate the results to physical activity, blood pressure and biochemical findings and to follow exercise capacity over time.Methods: Patients with KT (n = 38, age 7.7–18 years), with a mean time from transplantation of 3.7 years (0.9–13.0) and mean time in dialysis 0.8 years, were examined at inclusion and annually for up to three years. Healthy controls (n = 17, age 7.3–18.6 years) were examined once. All subjects underwent a cardiopulmonary exercise test, resting blood pressure measurement, anthropometry and activity assessment. Patients also underwent echocardiography, dual-energy X-ray absorptiometry (DXA), 24-h ambulatory BP measurements (ABPM), assessment of glomerular filtration rate (GFR) and blood sampling annually.Results: As compared to healthy controls, KT patients showed decreased exercise capacity measured both as VO2peak (34.5 vs. 43.9 ml/kg/min, p &lt; 0.001) and maximal load (2.6 vs. 3.5 W/kg, p &lt; 0.0001), similarly as when results were converted to z-scores. No significant difference was found in weight, but the KT patients were shorter and had higher BMI z-score than controls, as well as increased resting SBP and DBP z-scores. The patient or parent reported physical activity was significantly lower in the KT group compared to controls (p &lt; 0.001) In the combined group, the major determinants for exercise capacity z-scores were activity score and BMI z-score (β = 0.79, p &lt; 0.0001 and β = −0.38, p = 0.007, respectively). Within the KT group, low exercise capacity was associated with high fat mass index (FMI), low activity score, low GFR and high blood lipids. In the multivariate analysis FMI and low GFR remained predictors of low exercise capacity. The longitudinal data for the KT patients showed no change in exercise capacity z-scores over time.Conclusion: Patients with KT showed decreased exercise capacity and increased BP as compared to healthy controls. Exercise capacity was associated to GFR, physical activity, FMI and blood lipids. It did not improve during follow-up.

Abstract Background and aim Patient activation (PA) and Patient Involvement (PI) are considered elements in good survivorship. We aimed to evaluate the effect of a follow-up supported by electronic patient-reported outcomes (ePRO) on PA and PI. Method From February 2017 to January 2019, we conducted an explorative interventional study. We included 187 patients followed after intended curative complex surgery for advanced cancer at two different Departments at a University Hospital. Prior to each follow-up consultation, patients used the ePRO to screen themselves for clinical important symptoms, function and needs. The ePRO was graphically presented to the clinician during the follow-up, aiming to facilitate patient activation and involvement in each follow-up. PA was measured by the Patient Activation Measurement (PAM), while PI was measured by five indicator questions. PAM and PI data compared between (− ePRO) and interventional (+ ePRO) consultations. PAM data were analysed using a linear mixed effect regression model with intervention (yes/no) and time along with the interaction between them as categorical fixed effects. The analyses were further adjusted for time (days) since surgery. Results According to our data, ePRO supported consultations did not improve PA. The average mean difference in PAM score between + ePRO and − ePRO consultations were − 0.2 (95% confidence interval − 2.6; 2.2, p = 0.9). There was no statistically significant improvement in PAM scores over time in neither + ePRO nor − ePRO group (p = 0.5). Based on the five PI-indicator questions, the majority of all consultations were evaluated as “some, much or very much” involved in consultation; providing a wider scope of dialogue, encouraged patients to ask questions and share their experiences and concerns. Nevertheless, another few patients reported not to be involved at all in the consultations. Conclusion We did not demonstrate evidence for ePRO supported consultations to improve patient activation, and patient activation did not improve over time. Our results generate the hypotheses that factors related to ePRO supported consultation had the potential to support PI by offering a wider scope of dialogue, and encourage patients to ask questions and share their experiences and concerns during follow-up.
