Metabolic Profile for Prediction of Ischemic Stroke in Chinese Hypertensive Population

Background

Stroke burden is extremely high in Chinese hypertensive population. Novel biomarkers for cardiovascular diseases can be detected by metabolomic profiling of human fluids. We aim to find a panel of distinctive plasma metabolites for predicting incident ischemic stroke in hypertensive patients.

Depressive symptoms in caregivers immediately after stroke

Background: Caregivers of stroke survivors often suffer depressive symptoms that interfere with their own health. Early recognition may lead to attenuation of symptoms and better health and well-being for caregivers.

Objective: We examined characteristics of caregivers and stroke survivors associated with caregivers’ depressive symptoms in the early poststroke period.

Methods: We conducted a prospective, longitudinal exploratory observational study with a convenience sample of 63 caregivers of older adult (≥ 65 years) stroke survivors recruited from urban acute-care settings. We enrolled caregivers by 2 weeks poststroke (T1) and revisited them 4 weeks later (T2). Depressive symptoms were measured using the Patient Health Questionnaire-9. A separate unadjusted linear mixed model was computed to explore significant associations between each caregiver or stroke-survivor characteristic and depressive symptoms.

Results: Caregivers, on average, reported mild depressive symptoms at T1 and T2. Each of the following characteristics was independently associated with caregiver depressive symptoms over the first 6 weeks poststroke: caregiver uncertainty (p < 0.001), perceived stress (p < 0.001) but not cortisol levels (p = 0.858 on waking, p = 0.231 evening), coping (p < 0.001), social support (p = 0.006), race (p = 0.022), income (p = 0.001), time spent on care (p = 0.039), and stroke-survivor race (p = 0.033) and functional status (p = 0.003). At T2, caregiver depressive symptoms were correlated with evening cortisol level (p = 0.001).

Conclusions: Caregiver and stroke-survivor characteristics may help identify caregivers at highest risk for early depressive symptoms and guide interventions aimed at their resolution.

Assessment of backward walking unmasks mobility impairments in post-stroke community ambulators

Background: While over half of stroke survivors recover the ability to walk without assistance, deficits persist in the performance of walking adaptations necessary for safe home and community mobility. One such adaptation is the ability to walk or step backward. Post-stroke rehabilitation rarely includes backward walking (BW) assessment and BW deficits have not been quantified in post-stroke community ambulators.

Objective: To quantify spatiotemporal and kinematic BW characteristics in post-stroke community ambulators and compare their performance to controls.

Methods: Individuals post-stroke (n = 15, 60.1 ± 12.9 years, forward speed: 1.13 ± 0.23 m/s) and healthy adults (n = 12, 61.2 ± 16.2 years, forward speed: 1.40 ± 0.13 m/s) performed forward walking (FW) and BW during a single session. Step characteristics and peak lower extremity joint angles were extracted using 3D motion analysis and analyzed with mixed-method ANOVAs (group, walking condition).

Results: The stroke group demonstrated greater reductions in speed, step length and cadence and a greater increase in double-support time during BW compared to FW (p < .01). Compared to FW, the post-stroke group demonstrated greater reductions in hip extension and knee flexion during BW (p < .05). The control group demonstrated decreased plantarflexion and increased dorsiflexion during BW, but these increases were attenuated in the post-stroke group (p < .05).

Conclusions: Assessment of BW can unmask post-stroke walking impairments not detected during typical FW. BW impairments may contribute to the mobility difficulties reported by adults post-stroke. Therefore, BW should be assessed when determining readiness for home and community ambulation.     

一期支架置入补救治疗急性后循环大动脉闭塞机械取栓术失败病人的疗效

目的 探讨一期支架置入术作为急性后循环大动脉闭塞机械取栓失败后补救性治疗的疗效。方法 回顾性分析2016年1月至2018年6月单独支架取栓或联合抽吸取栓治疗后循环大动脉闭塞所致急性脑卒中186例，146例实现闭塞血管成功再通；40例血流恢复较差，其中28例接受一期支架置入补救性治疗（支架组）；12例拒绝支架置入治疗（非支架组），仅给予基础抗栓治疗。结果 支架组血管再通率（75.00%）明显高于非支架组（0％；P<0.05）。术后90 d，支架组预后良好率（64.29%，改良Rankin量表评分0~2分）明显高于非支架组（8.33%；P<0.05）。支架组术后90 d病死率（21.43%）明显低于非支架组（83.33%；P<0.05）。支架组症状性颅内出血发生率（7.14%）与非支架组（16.67%）无统计学差异（P>0.05）。结论 一期支架置入术作为急性后循环大动脉闭塞机械取栓术失败的补救性治疗，再通率高，并发症少，可显著改善病人的预后。     

Ketorolac use and anastomotic leak in patients with esophageal cancer

ObjectivesRecent evidence has shown an association between postoperative ketorolac use and anastomotic leak in patients undergoing intestinal and colorectal operations, but this relationship has been minimally explored after esophagectomy. As the use of nonopioid pain control and enhanced recovery protocols is increasingly prioritized, determination of a possible correlation between perioperative ketorolac use and leak is essential.MethodsRecords of patients undergoing esophagectomy for adenocarcinoma at a single institution from 2006 to 2018 reviewed for occurrence of anastomotic leak. Institutional pharmacy records were queried for ketorolac administration during the surgical case through the time of discharge. Multivariable logistic regression was used to determine the relationship between ketorolac administration and anastomotic leak.ResultsA total of 1019 patients met inclusion criteria, the majority of whom were male (907, 89%) with a median age of 62 years. Patients predominantly presented with locoregionally advanced disease and were treated with initial chemoradiation. Ketorolac was administered to 686 patients (67%); use was observed to increase over the study period from 49% in 2006 to 92% in 2016. Conversely, anastomotic leak occurred in 87 patients (9%) overall and decreased over time from 15% (11/72) in 2006 to 2% (2/83) in 2018. Upon multivariable analysis, neither ketorolac administration evaluated as a categoric variable (odds ratio, 0.99; P = .958) or as a continuous variable using dose (odds ratio, 1.00; P = .843) demonstrated an association with anastomotic leak.ConclusionsKetorolac in the postoperative period after esophagectomy has become an integral component of enhanced recovery pathways and does not appear to be associated with anastomotic leak.     

Impact of Treatment Time on the Long-Term Outcome of Stroke Patients Treated With Mechanical Thrombectomy

Exercise Intolerance in Patients With Heart Failure: JACC State-of-the-Art Review

Exercise intolerance is the cardinal symptom of heart failure (HF) and is of crucial relevance, because it is associated with a poor quality of life and increased mortality. While impaired cardiac reserve is considered to be central in HF, reduced exercise and functional capacity are the result of key patient characteristics and multisystem dysfunction, including aging, impaired pulmonary reserve, as well as peripheral and respiratory skeletal muscle dysfunction. We herein review the different modalities to quantify exercise intolerance, the pathophysiology of HF, and comorbid conditions as they lead to reductions in exercise and functional capacity, highlighting the fact that distinct causes may coexist and variably contribute to exercise intolerance in patients with HF.
