    Abstract: The uptake of proven stroke treatments varies widely. We aimed to determine the association of evidence‐based processes of care for acute ischemic stroke ( AIS ) and clinical outcome of patients who participated in the HEADPOST (Head Positioning in Acute Stroke Trial), a multicenter cluster crossover trial of lying flat versus sitting up, head positioning in acute stroke. Methods and Results Use of 8 AIS processes of care were considered: reperfusion therapy in eligible patients; acute stroke unit care; antihypertensive, antiplatelet, statin, and anticoagulation for atrial fibrillation; dysphagia assessment; and physiotherapist review. Hierarchical, mixed, logistic regression models were performed to determine associations with good outcome (modified Rankin Scale scores 0–2) at 90 days, adjusted for patient and hospital variables. Among 9485 patients with AIS, implementation of all processes of care in eligible patients, or “defect‐free” care, was associated with improved outcome (odds ratio, 1.40; 95% CI, 1.18–1.65) and better survival (odds ratio, 2.23; 95% CI , 1.62–3.09). Defect‐free stroke care was also significantly associated with excellent outcome (modified Rankin Scale score 0–1) (odds ratio, 1.22; 95% CI , 1.04–1.43). No hospital characteristic was independently predictive of outcome. Only 1445 (15%) of eligible patients with AIS received all processes of care, with significant regional variations in overall and individual rates. Conclusions Use of evidence‐based care is associated with improved clinical outcome in AIS . Strategies are required to address regional variation in the use of proven AIS treatments.

    Abstract: We aim to compare the outcome of patients from urban areas, where the referral center is able to perform thrombectomy, with patients from nonurban areas enrolled in the RACECAT trial (Direct Transfer to an Endovascular Center Compared to Transfer to the Closest Stroke Center in Acute Stroke Patients With Suspected Large Vessel Occlusion). Methods: Patients with suspected large vessel occlusion stroke, as evaluated by a Rapid Arterial Occlusion Evaluation score of ≥5, from urban catchment areas of thrombectomy-capable centers during RACECAT trial enrollment period were included in the Stroke Code Registry of Catalonia. Primary outcome was disability at 90 days, as assessed by the shift analysis on the modified Rankin Scale score, in patients with an ischemic stroke. Secondary outcomes included mortality at 90 days, rate of thrombolysis and thrombectomy, time from onset to thrombolysis, and thrombectomy initiation. Propensity score matching was used to assemble a cohort of patients with similar characteristics. Results: The analysis included 1369 patients from nonurban areas and 2502 patients from urban areas. We matched 920 patients with an ischemic stroke from urban areas and nonurban areas based on their propensity scores. Patients with ischemic stroke from nonurban areas had higher degrees of disability at 90 days (median [interquartle range] modified Rankin Scale score, 3 [2–5] versus 3 [1–5], common odds ratio, 1.25 [95% CI, 1.06–1.48] ); the observed average effect was only significant in patients with large vessel stroke (common odds ratio, 1.36 [95% CI, 1.08–1.65]). Mortality rate was similar between groups(odds ratio, 1.02 [95% CI, 0.81–1.28] ). Patients from nonurban areas had higher odds of receiving thrombolysis (odds ratio, 1.36 [95% CI, 1.16–1.67]), lower odds of receiving thrombectomy(odds ratio, 0.61 [95% CI, 0.51–0.75] ), and longer time from stroke onset to thrombolysis (mean difference 38 minutes [95% CI, 25–52]) and thrombectomy(mean difference 66 minutes [95% CI, 37–95] ). Conclusions: In Catalonia, Spain, patients with large vessel occlusion stroke triaged in nonurban areas had worse neurological outcomes than patients from urban areas, where the referral center was able to perform thrombectomy. Interventions aimed at improving organizational practices and the development of thrombectomy capabilities in centers located in remote areas should be pursued.

    Abstract: We aim to assess whether time of day modified the treatment effect in the RACECAT trial (Direct Transfer to an Endovascular Center Compared to Transfer to the Closest Stroke Center in Acute Stroke Patients With Suspected Large Vessel Occlusion Trial), a cluster-randomized trial that did not demonstrate the benefit of direct transportation to a thrombectomy-capable center versus nearest local stroke center for patients with a suspected large vessel stroke triaged in nonurban Catalonia between March 2017 and June 2020. Methods: We performed a post hoc analysis of RACECAT to evaluate if the association between initial transport routing and functional outcome differed according to trial enrollment time: daytime (8:00 am –8:59 pm ) and nighttime (9:00 pm –7:59 am ). Primary outcome was disability at 90 days, as assessed by the shift analysis on the modified Rankin Scale score, in patients with ischemic stroke. Subgroup analyses according to stroke subtype were evaluated. Results: We included 949 patients with an ischemic stroke, of whom 258 patients(27%) were enrolled during nighttime. Among patients enrolled during nighttime, direct transport to a thrombectomy-capable center was associated with lower degrees of disability at 90 days (adjusted common odds ratio [acOR] , 1.620 [95% CI, 1.020–2.551]); no significant difference between trial groups was present during daytime (acOR, 0.890 [95% CI, 0.680–1.163] ; P interaction =0.014). Influence of nighttime on the treatment effect was only evident in patients with large vessel occlusion(daytime, acOR 0.766 [95% CI, 0.548–1.072]; nighttime, acOR, 1.785 [95% CI, 1.024–3.112] ; P interaction 〈 0.01); no heterogeneity was observed for other stroke subtypes ( P interaction 〉 0.1 for all comparisons). We observed longer delays in alteplase administration, interhospital transfers, and mechanical thrombectomy initiation during nighttime in patients allocated to local stroke centers. Conclusions: Among patients evaluated during nighttime for a suspected acute severe stroke in non-urban areas of Catalonia, direct transport to a thrombectomy-capable center was associated with lower degrees of disability at 90 days. This association was only evident in patients with confirmed large vessel occlusion on vascular imaging. Time delays in alteplase administration and interhospital transfers might mediate the observed differences in clinical outcome.

    Abstract: To measure the global impact of COVID-19 pandemic on volumes of IV thrombolysis (IVT), IVT transfers, and stroke hospitalizations over 4 months at the height of the pandemic (March 1 to June 30, 2020) compared with 2 control 4-month periods. Methods We conducted a cross-sectional, observational, retrospective study across 6 continents, 70 countries, and 457 stroke centers. Diagnoses were identified by their ICD-10 codes or classifications in stroke databases. Results There were 91,373 stroke admissions in the 4 months immediately before compared to 80,894 admissions during the pandemic months, representing an 11.5% (95% confidence interval [CI] −11.7 to −11.3, p 〈 0.0001) decline. There were 13,334 IVT therapies in the 4 months preceding compared to 11,570 procedures during the pandemic, representing a 13.2% (95% CI −13.8 to −12.7, p 〈 0.0001) drop. Interfacility IVT transfers decreased from 1,337 to 1,178, or an 11.9% decrease (95% CI −13.7 to −10.3, p = 0.001). Recovery of stroke hospitalization volume (9.5%, 95% CI 9.2–9.8, p 〈 0.0001) was noted over the 2 later (May, June) vs the 2 earlier (March, April) pandemic months. There was a 1.48% stroke rate across 119,967 COVID-19 hospitalizations. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection was noted in 3.3% (1,722/52,026) of all stroke admissions. Conclusions The COVID-19 pandemic was associated with a global decline in the volume of stroke hospitalizations, IVT, and interfacility IVT transfers. Primary stroke centers and centers with higher COVID-19 inpatient volumes experienced steeper declines. Recovery of stroke hospitalization was noted in the later pandemic months.

    Abstract: Obese women with large abdominal volume may present with elevated intra-abdominal and intravesical pressure due to their high body mass index (BMI), which leads to an imbalance in the mechanism responsible for urinary continence. Thus, these women have a 2-fold chance of developing urinary incontinence (UI) than nonobese women. Because increased BMI represents a risk factor for UI development, we hypothesize that its reduction could alleviate or decrease the symptoms of this condition in obese women. Therefore, the aim of this study was to describe the impact of weight loss on the severity of UI symptoms and quality of life (QoL) in women undergoing bariatric surgery. Methods This was a combined case-cohort study lasting 1 year, with 26 obese women aged 18 to 59 years who underwent bariatric surgery and presented preoperative UI. The participants’ BMI was calculated, their UI was assessed through the International Consultation on Incontinence Questionnaire–Short Form, and QoL by the King’s Health Questionnaire. Reassessments were performed at 3, 6, 9, and 12 postoperative months. Results We found no significant association between BMI reduction and prevalence and severity of UI. However, the 8-point reduction in BMI was sufficient to decrease the severity of UI. Quality of life improved significantly in 7 of the 9 domains evaluated. Conclusions According to the results of our study, we can conclude that the reduction in the prevalence and severity of UI together with weight loss induced by bariatric surgery was more evident in the first 3 months postoperatively, impacting positively the QoL of these women.

    Abstract: The prevalence of cognitive impairment is insufficiently determined in developing countries. The aim of this study was to ascertain the prevalence of cognitive impairment without dementia and dementia in community-dwelling elderly in Brazil. Methods: This was a single-phase cross-sectional survey of the elderly (aged 60 years and above) living in the municipality of Tremembé, Brazil. Twenty percent of the households with elderly persons were randomly selected from urban and rural areas, to obtain a homogenous representation of all socioeconomic and cultural levels. Results: We assessed 630 individuals [mean age, 71.3 y (±7.99); mean years of education, 4.9 (±4.54)] and found prevalence rates of 17.5% (95% confidence interval, 14.6-20.6) for dementia and 19.5% (95% confidence interval, 16.6-22.8) for cognitive impairment without dementia. These prevalence rates were influenced by age ( P 〈 0.001) and by educational level ( P 〈 0.001). There was no significant sex difference among diagnostic groups ( P =0.166). The prevalence of dementia was higher in relatively younger individuals (below 70 y) when compared with other studies. Besides, dementia was associated with low socioeconomic status, stroke, previous psychiatric disorder, alcoholism, and epilepsy. Conclusions: The prevalence of dementia in this study was higher than in other studies, particularly among younger elderly.

    In: Journal of Thoracic Imaging, Ovid Technologies (Wolters Kluwer Health), Vol. 36, No. 1 ( 2021-01), p. 31-36
    Abstract: An expert consensus recently proposed a standardized coronavirus disease 2019 (COVID-19) reporting language for computed tomography (CT) findings of COVID-19 pneumonia. Purpose: The purpose of the study was to evaluate the performance of CT in differentiating COVID-19 from other viral infections using a standardized reporting classification. Methods: A total of 175 consecutive patients were retrospectively identified from a single tertiary-care medical center from March 15 to March 24, 2020, including 87 with positive reverse transcription-polymerase chain reaction (RT-PCR) test for COVID-19 and 88 with negative COVID-19 RT-PCR test, but positive respiratory pathogen panel. Two thoracic radiologists, who were blinded to RT-PCR and respiratory pathogen panel results, reviewed chest CT images independently and classified the imaging findings under 4 categories: “typical” appearance, “indeterminate,” “atypical,” and “negative” for pneumonia. The final classification was based on consensus between the readers. Results: Patients with COVID-19 were older than patients with other viral infections ( P =0.038). The inter-rater agreement of CT categories between the readers ranged from good to excellent, κ=0.80 (0.73 to 0.87). Final CT categories were statistically different among COVID-19 and non-COVID-19 groups ( P 〈 0.001). CT “typical” appearance was more prevalent in the COVID-19 group (64/87, 73.6%) than in the non-COVID-19 group (2/88, 2.3%). When considering CT “typical” appearance as a positive test, a sensitivity of 73.6% (95% confidence interval [CI]: 63%-82.4%), specificity of 97.7% (95% CI: 92%-99.7%), positive predictive value of 97% (95% CI: 89.5%-99.6%), and negative predictive value of 78.9% (95% CI: 70%-86.1%) were observed. Conclusion: The standardized chest CT classification demonstrated high specificity and positive predictive value in differentiating COVID-19 from other viral infections when presenting a “typical” appearance in a high pretest probability environment. Good to excellent inter-rater agreement was found regarding the CT standardized categories between the readers.

    Abstract: To assess the prevalence of burnout, anxiety and depression symptoms, and posttraumatic stress disorder (PTSD) in PICU workers in Brazil during the first peak of the COVID-19 pandemic. To compare the results of subgroups stratified by age, gender, professional category, health system, and previous mental health disorders. DESIGN: Multicenter, cross-sectional study using an electronic survey. SETTING: Twenty-nine public and private Brazilian PICUs. SUBJECTS: Multidisciplinary PICU workers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Self-reported questionnaires were used to measure burnout (Maslach Burnout Inventory), anxiety and depression (Hospital Anxiety and Depression Scale), and PTSD (Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [PCL-5]) in 1,084 respondents. Subjects were mainly young (37.1 ± 8.4 yr old) and females (85%), with a median workload of 50 hours per week. The prevalence of anxiety and depression was 33% and 19%, respectively, whereas PTSD was 13%. The overall median burnout scores were high in the emotional exhaustion and personal accomplishment dimensions (16 [interquartile range (IQR), 8–24] and 40 [IQR, 33–44], respectively) whereas low in the depersonalization one (2 [IQR, 0–5] ), suggesting a profile of overextended professionals, with a burnout prevalence of 24%. Professionals reporting prior mental health disorders had higher prevalence of burnout (30% vs 22%; p = 0.02), anxiety (51% vs 29%; p 〈 0.001), and depression symptoms (32.5% vs 15%; p 〈 0.001), with superior PCL-5 scores for PTSD ( p 〈 0.001). Public hospital workers presented more burnout (29% vs 18.6%, p 〈 0.001) and more PTSD levels (14.8% vs 10%, p = 0.03). Younger professionals were also more burned out ( p 〈 0.05 in all three dimensions). CONCLUSIONS: The prevalence of mental health disorders in Brazilian PICU workers during the first 2020 peak of COVID-19 was as high as those described in adult ICU workers. Some subgroups, particularly those reporting previous mental disorders and younger professionals, should receive special attention to prevent future crises.

    Abstract: Red blood cell (RBC) distribution width (RDW) measures RBC variations in size. Higher RDW values have been associated with poor outcome in acute heart failure (HF). We aimed to assess the prognostic impact of the RDW in chronic HF. Methods We retrospectively analysed a cohort of chronic HF patients with left ventricular systolic dysfunction followed in our HF clinic between January 2012 and May 2018. Patients with missing data concerning RDW were excluded. Patients were categorized according to RDW tertiles: ≤13.5%; between 13.5 and 14.7%; and 〉 14.7%. Patients were followed until January 2021; all-cause mortality was the end point analysed. The association of RDW with all-cause mortality was assessed with a Cox-regression analysis. Two multivariate models were built. Results We studied 860 chronic HF patients, 66.4% males, mean age 70 (standard deviation, SD 13) years. Patients were followed for a median of 49 (29–82) months. During this period, 423 (49.2%) patients died. Mortality increased with increasing RDW tertiles. Patients with RDW 〉 14.7% had a HR of mortality of 1.95 (1.47–2.58), p   〈  0.001 (model 1) and of 1.81 (1.35–2.41), p   〈  0.001 (model 2) when compared with those with RDW ≤13.5. Patients in the second RDW tertile had an all-cause death HR of 1.47 (1.12–1.93) and of 1.44 (1.09–1.90) in models 1 and 2, respectively. Conclusions Chronic HF patients with RDW values 〉 14.7% presented an almost 2-fold higher risk of dying in the long term than those with RDW 〈 13.5%. RDW is a widely available and easily measured parameter that can help clinicians in the risk stratification of chronic HF patients.
