Abstract BACKGROUND: Recurrent hemorrhage is a serious neurosurgical problem in adult moyamoya disease (MMD) patients. OBJECTIVE: To find the natural history and risk factors of recurrent hemorrhage in cases of adult hemorrhagic MMD. METHODS: One hundred seventy-six adult MMD patients presenting with hemorrhage were enrolled. Patients’ medical records and radiological images were retrospectively reviewed. Clinical and radiological features of recurrent hemorrhage, and related risk factors were analyzed. Poor neurological outcome was defined as a score on the modified Rankin Scale of 4 to 6. The hemisphere in which the initial hemorrhage occurred was considered as the affected one. The mean follow-up duration was 83 months. RESULTS: The overall estimated rate of recurrent hemorrhage was 16.9%/person (95% confidence interval, 11.3%-24.8%) at 5 years and 26.3%/person (95% confidence interval, 18.5%-36.4%) at 10 years after the initial episode of hemorrhage. The affected hemisphere showed a higher recurrent hemorrhagic rate (11.7% vs 8.3%/hemisphere at 5 years, P = .09) after conservative treatment. As a result of recurrent hemorrhages, the number of patients with poor neurological outcome increased (first episode: 13.8%, second: 37.5%, third: 40.0%, fourth: 100%). The presence of intraventricular hemorrhage (P = .05, hazard ratio = 3.32) and bilateral MMD (P = .05, hazard ratio = 4.15) had a marginal significance for recurrent hemorrhage. Eight ischemic strokes (4.5%) including 4 postoperative infarctions were identified, and all ischemic strokes were minor stroke. CONCLUSION: During the follow-up period, recurrent hemorrhagic events continued to increase and deteriorated the patients’ neurological conditions. The presence of intraventricular hemorrhage was a significant risk factor of recurrent hemorrhage.

The purpose of the study was to investigate the natural history of insomnia and its association with depression and mortality. In 1983, 1,870 randomly selected subjects aged 45–65 years answered a questionnaire on sleep and health. Of the 1,604 survivors in 1995, 1,244 (77.6%) answered a new questionnaire with almost identical questions. Mortality data were collected for the 266 subjects that had died during the follow-up period. Chronic insomnia was reported by 36.0% of women and 25.4% of men (χ2 = 9.7; p < .01). About 75% of subjects with insomnia at baseline continued to have insomnia at follow-up. Insomnia in women predicted subsequent depression (odds ratio [OR] = 4.1; 95% confidence interval [CI] 2.1–7.2) but was not related to mortality. In men, insomnia predicted mortality (OR = 1.7; 95% CI 1.2–2.3), but after adjustment for an array of possible risk factors, this association was no longer significant. Men with depression at baseline had an adjusted total death rate that was 1.9 times higher than in the nondepressed men (95% CI: 1.2–3.0).

Abstract Background The actual usefulness of CV risk factor assessment in the prognostic evaluation of cancer patients treated with cardiotoxic treatment remains largely unknown. Design Prospective multicenter study in patients scheduled to receive anticancer therapy related with moderate/high cardiotoxic risk. Methods A total of 1324 patients underwent follow-up in a dedicated cardio-oncology clinic from April 2012 to October 2017. Special care was given to the identification and control of CV risk factors. Clinical data, blood samples and echocardiographic parameters were prospectively collected according to protocol, at baseline before cancer therapy and then at 3 weeks, 3 months, 6 months, 1 year, 1.5 years and 2 years after initiation of cancer therapy. Results At baseline, 893 patients (67.4%) presented at least 1 risk factor, with a significant number of patients newly diagnosed during follow-up. Individual risk factors were not related with worse prognosis during a 2-year follow-up. However, a higher Systemic Coronary Risk Estimation (SCORE) was significantly associated with higher rates of severe cardiotoxicity and all-cause mortality [HR 1.79 (95% CI 1.16–2.76) for SCORE 5–9 and HR 4.90 (95% CI 2.44–9.82) for SCORE ≥10 when compared with patients with lower SCORE (0–4)]. Conclusions This large cohort of patients treated with a potentially cardiotoxic regimen showed a significant prevalence of CV risk factors at baseline and significant incidence during follow-up. Baseline cardiovascular risk assessment using SCORE predicted severe cardiotoxicity and all-cause mortality. Therefore, its use should be recommended in the evaluation of cancer patients.

Abstract Background The effects of an intensive prevention program (IPP) for 12 months following 3-week rehabilitation after myocardial infarction (MI) have been proven by the randomized IPP trial. The present study investigates if the effects of IPP persist one year after termination of the program and if a reintervention after &gt;24 months (“prevention boost”) is effective. Methods In the IPP trial patients were recruited during hospitalization for acute MI and randomly assigned to IPP versus usual care (UC) one month after discharge (after 3-week rehabilitation). IPP was coordinated by non-physician prevention assistants and included intensive group education sessions, telephone calls, telemetric and clinical control of risk factors. Primary study endpoint was the IPP Prevention Score, a sum score evaluating six major risk factors. The score ranges from 0 to 15 points, with a score of 15 points indicating best risk factor control. In the present study the effects of IPP were investigated after 24 months – one year after termination of the program. Thereafter, patients of the IPP study arm with at least one insufficiently controlled risk factor were randomly assigned to a 2-months reintervention (“prevention boost”) vs. no reintervention. Results At long-term follow-up after 24 months, 129 patients of the IPP study arm were compared to 136 patients of the UC study arm. IPP was associated with a significantly better risk factor control compared to UC at 24 months (IPP Prevention Score 10.9±2.3 points in the IPP group vs. 9.4±2.3 points in the UC group, p&lt;0.01). However, in the IPP group a decrease of risk factor control was observed at the 24-months visit compared to the 12-months visit at the end of the prevention program (IPP Prevention Score 10.9±2.3 points at 24 months vs. 11.6±2.2 points at 12 months, p&lt;0.05, Figure 1). A 2-months reintervention (“prevention boost”) was effective to improve risk factor control during long-term course: IPP Prevention Score increased from 10.5±2.1 points to 10.7±1.9 points in the reintervention group, while it decreased from 10.5±2.1 points to 9.7±2.1 points in the group without reintervention (p&lt;0.05 between the groups, Figure 1). Conclusions IPP was associated with a better risk factor control compared to UC during 24 months; however, a deterioration of risk factors after termination of IPP suggests that even a 12-months prevention program is not long enough. The effects of a short reintervention after &gt;24 months (“prevention boost”) indicate the need for prevention concepts that are based on repetitive personal contacts during long-term course after coronary events.

Abstract Background In patients with type 2 diabetes (T2D), optimal management of cardiovascular (CV) risk factors is critical for primary prevention of CV disease. Purpose To describe the association of country income and patient socioeconomic factors with risk factor control in patients with T2D. Methods DISCOVER is a 37-country, prospective, observational study of 15,983 patients with T2D enrolled between January 2016 and December 2018 at initiation of 2nd-line glucose-lowering therapy and followed for 3 years. In patients without known CV disease with sub-optimally controlled risk factors at baseline, we examined achievement of risk factor control (HbA1c &lt;7%, BP &lt;140/90 mmHg, appropriate statin) at the 3 year follow-up. Countries were stratified by gross national income (GNI)/capita, per World Bank report. We explored variability across countries in risk factor control achievement using hierarchical logistic regression models and examined the association of country- and patient-level economic factors with risk factor control. Results Among 9,613 patients with T2D but without CV disease (mean age 57.2 years, 47.9% women), 83.1%, 37.5%, and 66.3% did not have optimal control of glucose, BP, and statins, respectively, at baseline. Of these, 40.8%, 55.5%, and 28.6% achieved optimal control at 3 years of follow-up. There was substantial variability in achievement of risk factor control across countries (Figure) but no association of country GNI/capita on achievement of risk factor control (Table). Insurance status, which differed substantially by GNI group, was strongly associated with glycemic control, with no insurance and public insurance associated with lower odds of patients achieving HbA1c &lt;7%. Conclusions In a global cohort of patients with T2D, a substantial proportion do not achieve risk factor control even after 3 years of follow-up. The variability across countries in risk factor control is not explained by the GNI/capita of the country.

An observational study was conducted to estimate prevalence and risk factors for carcass contamination by Salmonella and Campylobacter spp. in 60 lots of turkey slaughtered over 10 months in the province of Quebec, Canada. Carcass contamination was evaluated by the carcass rinse technique for about 30 birds per lot. Exposure to potential risk factors was evaluated with questionnaires, meteorological data, and cecal cultures. Multivariable binomial negative regression models were used for risk factor analysis. Prevalence of Salmonella-positive carcasses was 31.2% (95% confidence interval, 22.8 to 39.5%). Variables positively associated (P ≤ 0.05) with the proportion of lot-positive carcasses were ≥0.5% of carcass condemnation due to various pathologies, cecal samples positive for Salmonella, low wind speed during transportation, closure of lateral curtains of truck during transportation, and slaughtering on a weekday other than Monday. When only Salmonella-positive cecal culture lots were considered, the proportion of carcasses positive for Salmonella was significantly higher in lots exposed to a &gt;5°C outside temperature variation during transportation, slaughtered on a weekday other than Monday, and in which ≥4% of carcasses had visible contamination. Prevalence of Campylobacter-positive carcasses was 36.9% (95% confidence interval, 27.6 to 46.3%). The proportion of positive carcasses was significantly higher in lots with Campylobacter-positive cecal cultures and lots undergoing ≥2 h of transit to slaughterhouse. For lots with Campylobacter-positive cecal cultures, variables significantly associated with an increased incidence of carcass contamination were ≥4% of carcasses with visible contamination, crating for ≥8 h before slaughtering, and no antimicrobials used during rearing.

Background/Aim: Docetaxel (DTX) is metabolized by liver cytochromes P450 (CYP) 3A4 (CYP3A4) and 3A5 (CYP3A5) CYP3A4 activity is considered the main factor affecting the effectiveness in DTX clearance. We, therefore, explored the association between DTX-induced febrile neutropenia (FN) and concomitant polypharmacy involving CYP3A4 inhibitors in cancer patients. Patients and Methods: Among patients who received docetaxel, we compared the number of concomitant medications between patients with and without FN, and risk factors associated with FN were identified. Results: The total number of concomitant CYP3A4 inhibitors and substrates used was significantly higher in patients with FN [mean: 2.1 (95% confidence interval (CI)=1.5-2.9)] than in those without FN [mean: 1.4 (95% CI=1.0-1.8)] (p=0.01). The only risk factor for FN was the use of ≥2 concomitant CYP3A4 inhibitors and substrates in total (OR=4.82, 95% CI=1.77-14.1; p=0.002). Conclusion: Polypharmacy involving CYP3A4 inhibitors and substrates increases the risk of DTX-induced FN.

Object The purpose of this study was to examine the prevalence of intracranial cavernous malformations (CMs) in a large series of predominantly Caucasian patients with spinal cord CMs. The authors also studied the natural history of spinal CMs in patients who were treated nonoperatively. Methods The medical records of 67 consecutive patients (32 female and 35 male patients) in whom a spinal CM was diagnosed between 1994 and 2002 were reviewed. The patients’ mean age at presentation was 50 years (range 13–82 years). Twenty-five patients underwent resection of the lesion. Forty-two patients in whom the spinal CM was diagnosed using magnetic resonance (MR) imaging were followed expectantly. Thirty-three (49%) of 67 patients underwent both spinal and intracranial MR imaging. All available imaging studies were reviewed to determine the coexistence of an intracranial CM. Fourteen (42%) of the 33 patients with spinal CMs who underwent intracranial MR imaging harbored at least one cerebral CM in addition to the spinal lesion. Six (43%) of these 14 patients did not have a known family history of CM. Data obtained during the long-term follow-up period (mean 9.7 years, total of 319 patient-years) were available for 33 of the 42 patients with a spinal CM who did not undergo surgery. Five symptomatic lesional hemorrhages (neurological events), four of which were documented on neuroimaging studies, occurred during the follow-up period, for an overall event rate of 1.6% per patient per year. No patient experienced clinically significant neurological deficits due to recurrent hemorrhage. Conclusions As many as 40% of patients with a spinal CM may harbor a similar intracranial lesion, and approximately 40% of patients with coexisting spinal and intracranial CMs may have the nonfamilial (sporadic) form of the disease. Patients with symptomatic spinal CMs who are treated nonoperatively may have a small risk of clinically significant recurrent hemorrhage. The findings will aid in evaluation of surveillance images and in counseling of patients with spinal CMs, irrespective of family history.

Abstract Background Checkpoint inhibitors (CPI) have drastically improved metastatic cancer outcomes. However, immunotherapy is associated to multiple toxicities, including acute renal injury (AKI). Data about CPI related AKI are limited. Our aim was to determine risk factors for CPI related AKI, as well as its clinical characteristics and its impact on mortality in patients undergoing immunotherapy. Methods All patients under CPI at our center between March 2018 and May 2019, and with a follow up until April 2020, were included. Demographical, clinical data and laboratory results were collected. AKI was defined according to KDIGO guidelines. We performed a logistic regression model to identify independent risk factors for AKI and actuarial survival analysis to establish risk factors for mortality in this population. Results 759 patients were included, with a median age of 64 years. 59% were men and baseline median creatinine was 0.80 mg/dL. Most frequent malignance was lung cancer and 56% were receiving anti-PD1. 15.5% developed AKI during the follow-up. Age and baseline kidney function were identified as independent risk factors for AKI related ICI. At the end of follow-up, 52.3% patients had died. Type of cancer (not melanoma, lung or urogenital malignance), type of CPI (not CTLA4, PD-1, PD-L1 or their combination) and the presence of an episode of AKI were identified as risk factors for mortality. Conclusions 15.5% of patients under immunotherapy presented AKI. A single AKI episode was identified as an independent risk factor for mortality in these patients and age and baseline renal function were risks factors for the development of AKI.

Purpose: SAMMPRIS is the first stroke prevention trial to include protocol-driven aggressive management of multiple vascular risk factors. We sought to determine the impact of this protocol on early risk factor control in the trial. Materials and Methods: SAMMPRIS randomized 451 patients with symptomatic 70%-99% intracranial stenosis to aggressive medical management or stenting plus aggressive medical management at 50 USA sites. For the primary risk factor targets (SBP < 140 mm/Hg (<130 if diabetic) and LDL < 70 mg/dL), the study neurologists follow medication titration algorithms and risk factor medications are provided to the patients. Secondary risk factors (diabetes, non-HDL, weight, exercise, and smoking cessation) are managed with assistance from the patient’s primary care physician and a lifestyle modification program (provided). Sites receive patient-specific recommendations and feedback to improve performance. Follow-up continues, but the 30-day data are final. We compared baseline to 30-day risk factor measures using paired t-tests for means and McNemar tests for percentages. Results: The differences in risk factor measures between baseline and 30 days are shown in Table 1. Conclusions: The SAMMPRIS protocol resulted in major improvements in controlling most risk factors within 30 days of enrollment, which may have contributed to the lower than expected 30 day stroke rate in the medical group (5.8%). However, the durability of this approach over time will be determined by additional follow-up.

Background and Purpose: Research suggests that depression may contribute to stroke risk independent of other known risk factors. Most studies examining the impact of depression on stroke have been conducted with predominantly white cohorts, though blacks are known to have higher stroke incidence than whites. The purpose of this study was to examine depressive symptoms as a risk factor for incident stroke in blacks and whites, and determine whether depressive symptomatology was differentially predictive of stroke among blacks and whites. Methods: The REasons for Geographic and Racial Differences in Stroke (REGARDS), is a national, population-based longitudinal study designed to examine risk factors associated with black-white and regional disparities in stroke incidence. Among 30,239 participants (42% black) accrued from 2003-2007, excluding those lacking follow-up or data on depressive symptoms, 27,557 were stroke-free at baseline. As of the January 2011 data closure, over an average follow-up of 4.6 years, 548 incident stroke cases were verified by study physicians based on medical records review. The association between baseline depressive symptoms (assessed via the Center for Epidemiological Studies Depression scale, 4-item version) and incident stroke was analyzed with Cox proportional hazards models adjusted for demographic factors (age, race, and sex), stroke risk factors (hypertension, diabetes, smoking, atrial fibrillation, and history of heart disease), and social factors (education, income, and social network). Results: For the total sample, depressive symptoms were predictive of incident stroke. The association between depressive symptoms and stroke did not differ significantly based on race (Wald X 2 = 2.38, p = .1229). However, race-stratified analyses indicated that the association between depressive symptoms and stroke was stronger among whites and non-significant among blacks. Conclusions: Depressive symptoms were an independent risk factor for incident stroke among a national sample of blacks and whites. These findings suggest that assessment of depressive symptoms may warrant inclusion in stroke risk scales. The potential for a stronger association in whites than blacks requires further study.
