RESUMEN

Importance: Few stroke survivors meet recommended cardiovascular goals, particularly among racial/ethnic minority populations, such as Black or Hispanic individuals, or socioeconomically disadvantaged populations. Objective: To determine if a chronic care model-based, community health worker (CHW), advanced practice clinician (APC; including nurse practitioners or physician assistants), and physician team intervention improves risk factor control after stroke in a safety-net setting (ie, health care setting where all individuals receive care, regardless of health insurance status or ability to pay). Design, Setting, and Participants: This randomized clinical trial included participants recruited from 5 hospitals serving low-income populations in Los Angeles County, California, as part of the Secondary Stroke Prevention by Uniting Community and Chronic Care Model Teams Early to End Disparities (SUCCEED) clinical trial. Inclusion criteria were age 40 years or older; experience of ischemic or hemorrhagic stroke or transient ischemic attack (TIA) no more than 90 days prior; systolic blood pressure (BP) of 130 mm Hg or greater or 120 to 130 mm Hg with history of hypertension or using hypertensive medications; and English or Spanish language proficiency. The exclusion criterion was inability to consent. Among 887 individuals screened for eligibility, 542 individuals were eligible, and 487 individuals were enrolled and randomized, stratified by stroke type (ischemic or TIA vs hemorrhagic), language (English vs Spanish), and site to usual care vs intervention in a 1:1 fashion. The study was conducted from February 2014 to September 2018, and data were analyzed from October 2018 to November 2020. Interventions: Participants randomized to intervention were offered a multimodal coordinated care intervention, including hypothesized core components (ie, ≥3 APC clinic visits, ≥3 CHW home visits, and Chronic Disease Self-Management Program workshops), and additional telephone visits, protocol-driven risk factor management, culturally and linguistically tailored education materials, and self-management tools. Participants randomized to the control group received usual care, which varied by site but frequently included a free BP monitor, self-management tools, and linguistically tailored information materials. Main Outcomes and Measures: The primary outcome was change in systolic BP at 12 months. Secondary outcomes were non-high density lipoprotein cholesterol, hemoglobin A1c, and C-reactive protein (CRP) levels, body mass index, antithrombotic adherence, physical activity level, diet, and smoking status at 12 months. Potential mediators assessed included access to care, health and stroke literacy, self-efficacy, perceptions of care, and BP monitor use. Results: Among 487 participants included, the mean (SD) age was 57.1 (8.9) years; 317 (65.1%) were men, and 347 participants (71.3%) were Hispanic, 87 participants (18.3%) were Black, and 30 participants (6.3%) were Asian. A total of 246 participants were randomized to usual care, and 241 participants were randomized to the intervention. Mean (SD) systolic BP improved from 143 (17) mm Hg at baseline to 133 (20) mm Hg at 12 months in the intervention group and from 146 (19) mm Hg at baseline to 137 (22) mm Hg at 12 months in the usual care group, with no significant differences in the change between groups. Compared with the control group, participants in the intervention group had greater improvements in self-reported salt intake (difference, 15.4 [95% CI, 4.4 to 26.0]; P = .004) and serum CRP level (difference in log CRP, -0.4 [95% CI, -0.7 to -0.1] mg/dL; P = .003); there were no differences in other secondary outcomes. Although 216 participants (89.6%) in the intervention group received some of the 3 core components, only 35 participants (14.5%) received the intended full dose. Conclusions and Relevance: This randomized clinical trial of a complex multilevel, multimodal intervention did not find vascular risk factor improvements beyond that of usual care; however, further studies may consider testing the SUCCEED intervention with modifications to enhance implementation and participant engagement. Trial Registration: ClinicalTrials.gov Identifier: NCT01763203.

RESUMEN

OBJECTIVES: Although healthy lifestyle practices mitigate recurrent stroke risk and mortality, few stroke survivors adhere to them, particularly among socioeconomically disadvantaged communities. We developed and pilot tested a occupational therapy-based lifestyle management intervention, Healthy Eating And Lifestyle after Stroke (HEALS), to improve stroke survivors' self-management skills relating to diet and physical activity and evaluated it in a diverse safety-net population. MATERIALS AND METHODS: One hundred English- or Spanish-speaking participants with stroke or transient ischemic attack were randomized to a 6-week occupational therapist-led group lifestyle intervention vs. usual care. Each of the six 2-h group sessions included didactic presentations on diet and physical activity, peer exchange, personal exploration with goal setting, and direct experience through participation in a relevant activity. Primary outcomes at 6 months were change in body mass index, fruit/vegetable intake, and physical activity. Secondary outcomes included change in waist circumference, smoking, blood pressure, high-density lipoprotein, low-density lipoprotein, triglyceride, total cholesterol, glycosylated hemoglobin levels, quality of care, and perceptions of care. Effect sizes were determined in preparation for a larger randomized controlled trial powered to detect a difference in primary outcomes. A nested formative evaluation assessed facilitators and barriers to implementation, acceptance, and intervention adherence. RESULTS: There were no significant changes in primary or secondary outcomes at 6 months. Effect sizes for all outcomes were small (< 0.2). Focus group participants recommended extending the intervention program duration with more sessions, additional information on stroke and vascular risk factors, an interdisciplinary approach, additional family involvement, and incentives. Providers recommended longer program duration, more training, fidelity checks to ensure standardized program delivery, and additional incentives for participants. CONCLUSIONS: The HEALS intervention was feasible in a safety-net setting, but effect sizes were small. A longer-duration intervention, with intervener fidelity checks may be warranted. TRIAL REGISTRATION: NCT01550822.

RESUMEN

We report 7 cases of melioidosis in Colombia and comparision of 4 commercial systems for identifying Burkholderia pseudomallei. Phoenix systems were not a definitive method for identifying B. pseudomallei. For accurate identification, we recommend including this bacterium in the library databases of matrix-assisted laser desorption/ionization mass spectrometry systems in Latin America.

RESUMEN

BACKGROUND: Stroke survivors have high rates of subsequent cardiovascular and recurrent cerebrovascular events, and mortality. While healthy lifestyle practices - including a diet rich in fruits and vegetables, limited alcohol intake, and regular physical activity - can mitigate these outcomes, few stroke survivors adhere to them. Minorities from socioeconomically disadvantaged communities who obtain care in safety-net health systems experience the most barriers to implementing healthy lifestyle changes after stroke. PURPOSE: To report the design of Healthy Eating and Lifestyle After Stroke (HEALS), a randomized controlled trial (RCT) was designed to test the feasibility of using a manualized, lifestyle management intervention in a safety-net setting to improve lifestyle practices among ethnically diverse individuals with stroke or transient ischemic attack (TIA). METHODS: Design: Pilot RCT. PARTICIPANTS: Inclusion criteria: 1) Adults (≥40 years) with ischemic stroke or TIA (≥ 90 days prior); 2) English- or Spanish-speaking. SETTING: Outpatient clinic, safety-net setting. INTERVENTION: Weekly two-hour small group sessions led by an occupational therapist for six weeks. The sessions focused on implementing nutrition, physical activity, and self-management strategies tailored to each participant's goals. MAIN OUTCOME MEASURES: Body mass index, diet, and physical activity. CONCLUSIONS: Recruitment for this study is complete. If the HEALS intervention study is feasible and effective, it will serve as a platform for a large-scale RCT that will investigate the efficacy and cost-effectiveness of life management interventions for racially and ethnically diverse, low-income individuals with a history of stroke or TIA who seek healthcare in the safety-net system.

RESUMEN

Introduction Hypophysitis is a chronic inflammation of the pituitary gland of complex and still incompletely defined pathogenesis. It belongs to the group of non-hormonesecreting sellar masses, sharing with them comparable clinical presentation and radiographic appearance. Objectives Describe the case of immunoglobulin G4 (IgG4)-related hypophysitis presenting as a mass in the sphenoid sinus. Resumed Report A 40-year-old Brazilian man had a diagnosis of central diabetes insipidus since 2001 associated with pituitary insufficiency. Pituitary magnetic resonance imaging revealed a centered pituitary stalk with focal nodular thickening and the presence of heterogeneous materials inside the sphenoid sinus. The patient was treated with testosterone replacement therapy. Laboratory results revealed increased IgG4 serum. Conclusion IgG4-related hypophysitis should be considered in patients with pituitary insufficiency associated with sellar mass and/or thickened pituitary stalk. IgG4 serum measurement for early diagnosis of IgG4-related hypophysitis should be performed.

RESUMEN

La eficacia del reflejo estapedial en la determinación del umbral auditivo, utilizando la diferencia tono - ruido, fue evaluada en pacientes normales y con hipoacusia superficial y media. A ambos grupos de pacientes se les practicó la audiometría tonal, impedanciometría y determinación del reflejo estapedial con tono y ruido blanco. Se encontró que los valores del umbral auditivo con el reflejo estapedial fue menor de 20 dB HL para los pacientes normales y entre 30 y 40 dB HL para los hipoacúsicos. Estos valores se aproximaron bastante a los obtenidos con la audiometría tonal, no evidenciándose diferencias estadísticamente significativas entre ambos métodos
