The Impact

Cholinesterase inhibitors (ChEIs) are the mainstays of symptomatic treatment of Alzheimer’s disease (AD); however, their efficacy is limited, and their use was associated with deaths in some groups of patients. The aim of the current study was to assess the impact of the long-term use of ChEIs on mortality in patients with AD. This observational, longitudinal study included 1171 adult patients with a diagnosis of AD treated with donepezil or rivastigmine. Each patient was observed for 24 months or until death. The cognitive and functional assessments, the use of ChEIs, memantine, antipsychotics, antidepressants, and anxiolytics were recorded. The total number of deaths at the end of the observational period was 99 (8.45%). The patients who had received rivastigmine treatment were at an increased risk of death in the follow-up period. The higher risk of death in the rivastigmine group remained significant in multivariate Cox regression models.

Background and Purpose: The association between physical activity (PA) and lower risk of stroke is well established, but the relationship between leisure sedentary time and stroke is less well studied. Methods: We used 9 years of the Canadian Community Health Survey between 2000 and 2012 to create a cohort of healthy individuals without prior stroke, heart disease, or cancer. We linked to hospital records to determine subsequent hospitalization or emergency department visit for stroke until December 31, 2017. We quantified the association between self-reported leisure sedentary time (categorized as <4, 4 to <6, 6 to <8, and 8+ hours/day) and risk of stroke using Cox regression models and competing risk regression, assessing for modification by PA, age, and sex and adjusting for demographic, vascular, and social factors. Results: There were 143 180 people in our cohort and 2965 stroke events in follow-up. Median time from survey response to stroke was 5.6 years. There was a 3-way interaction between leisure sedentary time, PA, and age. The risk of stroke with 8+ hours of sedentary time was significantly elevated only among individuals <60 years of age who were in the lowest PA quartile (fully adjusted hazard ratio, 4.50 [95% CI, 1.64–12.3]). The association was significant across multiple sensitivity analyses, including adjustment for mood disorders and when accounting for the competing risk of death. Conclusions: Excess leisure sedentary time of 8+ hours/day is associated with increased risk of long-term stroke among individuals <60 years of age with low PA. These findings support efforts to enhance PA and reduce sedentary time in younger individuals.

Chronic periodontitis (CP) is associated with cardiovascular disease and mortality in different populations. The aim of this study was to examine an association of CP with hard endpoints in patients after kidney transplantation during a 15-year follow-up period. Study group consist of 117 patients (77M/40F, median age 44 years) divided into two subgroups: those with initially advanced CP (CPITN 3–4) and those with no or moderate CP (CPITN 0–2). All cardiovascular events, graft losses, and re-transplantations were recorded. All deaths were noted and verified, including those occurred after the return to dialysis therapy, the causes of death were identified. Cox regression with Firth’s penalized maximum likelihood models were used for data analysis. During the observation period, 49 deaths occurred. Advanced CP (n = 35) was not associated with overall mortality but was associated with increased risk of death with functioning graft (DWFG) [HR 3.54 (1.20–10.45); p < 0.05]. Risk of graft loss was not associated with CP status. In conclusion, an advanced CP was independently associated with increased risk of DWFG, but not all-cause or cardiovascular mortality after renal transplantation.

The Impact

The most relevant comorbidities in patients with peripheral artery disease (PAD) are coronary artery disease (CAD) and diabetes mellitus (DM). However, data of long-term follow-up of patients with chronic total occlusion (CTO) are scarce. The aim of the study was to assess the impact of CAD and DM on long-term follow-up patients after superficial femoral artery (SFA) CTO retrograde recanalization. In this study, eighty-six patients with PAD with diagnosed CTO in the femoropopliteal region and at least one unsuccessful attempt of antegrade recanalization were enrolled in 2 clinical centers. Mean time of follow-up in all patients was 47.5 months (±40 months). Patients were divided into two groups depending on the presence of CAD (CAD group: n=45 vs. non-CAD group: n=41) and DM (DM group: n=50 vs. non-DM group: n=36). In long-term follow-up, major adverse peripheral events (MAPE) occurred in 66.6% of patients with CAD vs. 36.5% of patients without CAD and in 50% of patients with DM vs. 55% of non-DM subjects. There were no statistical differences in peripheral endpoints in both groups. However, there was a statistically significant difference in all-cause mortality: in the DM group, there were 6 deaths (12%) (P value = 0.038). To conclude, patients after retrograde recanalization, with coexisting CTO and DM, are at higher risk of death in long-term follow-up.

AbstractTakotsubo syndrome (TTS) is an acute heart failure syndrome with significant rates of in and out-of-hospital mayor cardiac adverse events (MACE). To evaluate the possible role of neoplastic biomarkers [CA-15.3, CA-19.9 and Carcinoembryonic Antigen (CEA)] as prognostic marker at short- and long-term follow-up in subjects with TTS. Ninety consecutive subjects with TTS were enrolled and followed for a median of 3 years. Circulating levels of CA-15.3, CA-19.9 and CEA were evaluated at admission, after 72 h and at discharge. Incidence of MACE during hospitalization and follow-up were recorded. Forty-three (46%) patients experienced MACE during hospitalization. These patients had increased admission levels of CEA (4.3 ± 6.2 vs. 2.2 ± 1.5 ng/mL, p = 0.03). CEA levels were higher in subjects with in-hospital MACE. At long term follow-up, CEA and CA-19.9 levels were associated with increased risk of death (log rank p < 0.01, HR = 5.3, 95% CI 1.9–14.8, HR = 7.8 95% CI 2.4–25.1, respectively, p < 0.01). At multivariable analysis levels higher than median of CEA, CA-19.9 or both were independent predictors of death at long term (Log-Rank p < 0.01). Having both CEA and CA-19.9 levels above median (> 2 ng/mL, > 8 UI/mL respectively) was associated with an increased risk of mortality of 11.8 (95% CI 2.6–52.5, p = 0.001) at follow up. Increased CEA and CA-19.9 serum levels are associated with higher risk of death at long-term follow up in patients with TTS. CEA serum levels are correlated with in-hospital MACE.

Objectives: Alzheimer's disease (AD) is the most common cause of dementia and it is associated with increased mortality. The use of antipsychotics is common among the elderly, especially in those with dementia. Evidence suggests an increased risk of mortality associated with antipsychotic use. Despite the short-term benefit of antipsychotic treatment to reduce the behavioral and psychological symptoms of dementia, it increases the risk of mortality in patients with AD. Our aim is to discuss the findings from the literature about risk of mortality associated with the use of antipsychotics in AD.Methods: We searched Internet databases indexed at MEDLINE using following MeSH terms: "Antipsychotic Agents" AND "Alzheimer Disease" OR "Dementia" AND "Mortality" and selected articles published in the last 5 years.Results: Antipsychotics are widely used in the pharmacological treatment of agitation and aggression in elderly patients with AD, but their benefit is limited. Serious adverse events associated with antipsychotics include increased risk of death. The risk of mortality is associated with both typical and atypical antipsychotics. Antipsychotic polypharmacy is associated with a higher mortality risk than monotherapy and should be avoided. The mortality risk increases after the first few days of treatment, gradually reducing but continues to increase after two years of treatment. Haloperidol is associated with a higher mortality risk and quetiapine with a lower risk than risperidone.Conclusions: If the use of antipsychotics is considered necessary, the lowest effective dose should be chosen and the duration should be limited because the mortality risk remains high with long-term use. The risk / benefit should be considered when choosing the antipsychotic. Further studies on the efficacy and risk of adverse events with antipsychotics are needed for a better choice of treatment and adequate monitoring with risk reduction.

The Central Nervous System

As a global problem that has increasingly been causing worldwide concern, air pollution poses a significant and serious environmental risk to health. Risks of cardiovascular and respiratory diseases, as well as various types of cancer, have been consistently associated with the exposure to air pollutants. More recently, various studies have also shown that the central nervous system is also attacked by air pollution. Air pollution appears to be strongly associated with a higher risk of cognitive defects, neurodevelopmental (e.g., schizophrenia) and neurodegenerative (e.g., Alzheimer’s disease) disorders. Subjects with schizophrenia, as well as subjects with Alzheimer’s disease, experience a variety of neuropsychological deficits and cognitive impairments. This determines an adverse effect on social and professional functioning, and it contributes to the long-term disease burden. However, no final conclusions have been drawn on the matter of the direct relationship between schizophrenia and Alzheimer’s disease. In recent years, the topic of urbanicity and mental health has become increasingly important. Urban exposure to environmental toxins and pollution is currently described as a reliable risk factor for schizophrenia and other psychoses, and it has been demonstrated more and more how exposure to air pollutants is associated with increased risk of dementia. Pathways by which air pollution can target and damage the brain, leading to an increased risk for developing schizophrenia and Alzheimer’s disease, are multiple and complex. Results from epidemiological studies suggest potential associations, but are still insufficient to confirm causality. Further studies are needed in order to verify this hypothesis. And if confirmed, the clinical implications could be of substantial relevance for both public and mental health.

Several studies with animal research associate air pollution in Alzheimer’s disease (AD) neuropathology, but the actual impact of air pollution on the risk of AD is unknown. Here, this study investigates the association between long-term exposure to ozone (O3) and particulate matter (PM) with an aerodynamic diameter equal to or less than 2.5 μm (PM2.5), and newly diagnosed AD in Taiwan. We conducted a cohort study of 95,690 individuals’ age ≥ 65 during 2001–2010. We obtained PM10 and O3 data from Taiwan Environmental Protection Agency during 2000–2010. Since PM2.5 data is only accessible entirely after 2006, we used the mean ratio between PM2.5 and PM10 during 2006–2010 (0.57) to estimate the PM2.5 concentrations from 2000 to 2005. A Cox proportional hazards model was used to evaluate the associations between O3 and PM2.5 at baseline and changes of O3 and PM2.5 during the follow-up period and AD. The adjusted HR for AD was weakly associated with a raised concentration in O3 at baseline per increase of 9.63 ppb (adjusted HR 1.06, 95% confidence interval (CI) 1.00–1.12). Further, we estimated a 211% risk of increase of AD per increase of 10.91 ppb in O3 over the follow-up period (95% CI 2.92–3.33). We found a 138% risk of increase of AD per increase of 4.34 μg/m3 in PM2.5 over the follow-up period (95% CI 2.21–2.56). These findings suggest long-term exposure to O3 and PM2.5 above the current US EPA standards are associated with increased the risk of AD.

Abstract Environmental asbestos exposure and occupational asbestos exposure increase the risk of several types of cancer, but the role of such exposures for haematological malignancies remains controversial. We aimed to examine the risk of haematological malignancies: first, in subjects exposed early in life, independently of any occupational exposure occurring later; second, in subjects exposed occupationally. We established an environmentally exposed cohort from four schools located near the only former asbestos cement production plant in Denmark. We identified nearly all pupils in the seventh grade and created an age and sex-matched 1:9 reference cohort from the Danish Central Population Register. Participants were born 1940–1970 and followed up in national registers until the end of 2015. Occupational asbestos exposure was assessed for all participants using two different job exposure matrices. The school cohort included 12,111 participants (49.7% girls) and the reference cohort 108,987 participants. Eight subgroups of haematological malignancy were identified in the Danish Cancer Registry. These cases were analysed for combined overall haematological malignancy, a combined subgroup of lymphomas and a combined subgroup of leukaemias. The data were analysed using Cox regression (hazard ratios (HR)) including other cancers and death as competing risks. Haematological malignancy was identified in 1125 participants. The median follow-up was 49.3 years (0.1–63.4). Early environmental asbestos exposure was not associated with an increased risk of haematological malignancy. Long-term occupational asbestos exposure was associated with overall haematological malignancy (HR 1.69, 95% CI 1.04–2.73); in particular for the leukaemia subgroup (HR 2.14, 95% CI 1.19–3.84). This large follow-up study suggests that long-term occupational asbestos exposure is associated with increased leukaemia risk. However, further studies are needed to confirm these observations.

Abstract Background For recanalization of coronary chronic total occlusion (CTO) lesions, subintimal guidewire tracking in both antegrade and retrograde approaches are commonly used. Purpose This study aimed to assess the impact of subintimal tracking on long-term clinical outcomes after recanalization of CTO lesions. Methods Between January 2009 and December 2016, 474 CTO lesions (434patients) were successfully recanalized in our center. After guidewire crossing in a CTO lesion, those lesions were divided into intimal tracking group (84.6%, n=401) and subintimal tracking group (15.4%, n=73) according to intravascular ultrasound (IVUS) findings. Long-term clinical outcomes including death, target lesion revascularization (TLR), target vessel revascularization (TVR) were compared between the two groups. In addition, the rate of re-occlusion after successful revascularization was also evaluated. Results The median follow-up period was 4.7 years (interquartile range, 2.8–6.1). There was no significant difference of the rate of cardiac death between the two groups (intimal tracking vs. subintimal tracking: 7.0% vs. 4.1%; hazard ratio, 0.61; 95% confidence interval [CI], 0.19 to 2.00; p=0.41), TLR (14.3% vs. 16.2%; hazard ratio, 1.34; 95% CI, 0.71 to 2.53; p=0.37), and TVR (17.5% vs. 20.3%; hazard ratio, 1.27; 95% CI, 0.72 to 2.23; p=0.42). However, the rate of re-occlusion was significantly higher in the subintimal tracking group than intimal tracking group at 3-years re-occlusion (4.2% vs. 14.5%; log-rank test, p=0.002, Figure). In the multivariate COX regression, subintimal guidewire tracking was an independent predictor of re-occlusion after CTO recanalization (HR: 5.40; 95% CI: 2.11–13.80; p<0.001). Figure 1 Conclusions Subintimal guidewire tracking for recanalization of coronary CTO was associated with significantly higher incidence of target lesion re-occlusion during long-term follow-up period.

Anticholinergic Burden

Abstract Background Use of anticholinergic medication is associated with an increased risk of cognitive impairment and/or dementia. Despite this, the impact of continuing medication with anticholinergic properties in those diagnosed with Alzheimer’s Disease (AD) is not clear. Methods Analysis of data from NILVAD, an 18-month randomized controlled trial of Nilvadipine in AD. Effects of ongoing Anticholinergic Cognitive Burden (ACB) on cognition (ADAS-Cog: Alzheimer’s Disease Cog Subsection) and dementia severity (CDR-sb: Clinical Dementia Rating – Sum of Boxes/DAD: Disability Assessment for Dementia) over 18 months was evaluated adjusting for important clinical covariates. Results Just over one-quarter (27.90%, n = 142/510) of patients with mild to moderate AD were prescribed a potential/definite anticholinergic. While ACB score was not associated with greater progression on the ADAS-Cog/CDR-sb over time, a higher total ACB predicted greater dementia severity on the DAD, which persisted after robust covariate adjustment (β Coef: −1.53, 95% CI: −2.83 to −0.23, p = .021). There was a significant interaction between APOE ε4 status and ACB score, with carriers experiencing greater progression on both the CDR-Sb (β Coef: 0.36, 95% CI: 0.05–0.67, p = .021) and DAD (β Coef: −3.84, 95% CI: −7.65 to 0.03, p = .049). Conclusions Ongoing use of anticholinergic medication was associated with greater dementia progression on the DAD, but not the CDR-sb. APOE ε 4 carriers may be particularly vulnerable to the effect of ongoing anticholinergic medication on dementia severity, with significant APOE ε 4 x ACB score interactions demonstrated on both the DAD and CDR-sb.
