RESUMO

The presence of spontaneous echo contrast on ultrasonography is a predisposition to increased thromboembolic risk. The purpose of this study was to assess for the prevalence and consequences of spontaneous echo contrast on point-of-care vascular ultrasound in coronavirus disease 2019. DESIGN SETTING AND PATIENTS: This was a retrospective cohort study of 39 adult patients admitted to the ICU with a confirmed coronavirus disease 2019 diagnosis at a large tertiary-care academic medical center. Patients were included if they had undergone a vascular ultrasound examination during their ICU admission. Overall, 48 venous ultrasound studies among the 39 patients were reviewed in blinded fashion by two reviewers for the presence of venous spontaneous echo contrast, and charts were analyzed for laboratory data and outcomes. MEASUREMENTS AND MAIN RESULTS S: pontaneous echo contrast correlated with serum viscosity (mean values of 2.64, 2.54, and 2.04 cP for dense spontaneous echo contrast, spontaneous echo contrast , and no spontaneous echo contrast, respectively, with a p value of 0.0056 for spontaneous echo contrast compared with negative spontaneous echo contrast) and hyperfibrinogenemia (mean values of 726.6, 668.5, and 566.6 mg/dL for dense spontaneous echo contrast, positive spontaneous echo contrast, and negative spontaneous echo contrast, respectively, with a p value of 0.0045 for dense spontaneous echo contrast compared with negative spontaneous echo contrast). About 36% of patients with dense spontaneous echo contrast and 33% of individuals with positive spontaneous echo contrast experienced significant clotting events compared with 17% of those with negative spontaneous echo contrast. A total of 19% of patients with spontaneous echo contrast suffered a cardiac arrest following a major clotting event, and there were no cardiac arrests from clotting events in the negative spontaneous echo contrast group. There was no association with the presence of spontaneous echo contrast and right or left cardiac function or other laboratory values such as d-dimer, external thromboelastometry - maximum lysis, platelet counts, C-reactive protein, or interleukin-6. CONCLUSIONS: Point-of-care venous ultrasonography is easily performed and reliably interpreted for visualization of spontaneous echo contrast. The presence of spontaneous echo contrast in patients with coronavirus disease 2019 is associated with hyperviscosity and increased rates of thrombotic events and complications.

RESUMO

Background: To address disparities in smoking rates, our safety-net hospital implemented an inpatient tobacco treatment intervention: an "opt-out" electronic health record (EHR)-based Best Practice Alert + order-set, which triggers consultation to a Tobacco Treatment Consult (TTC) service for all hospitalized patients who smoke cigarettes. We report on development, implementation, and adaptation of the intervention, informed by a pre-implementation needs assessment and two rapid-cycle evaluations guided by the Consolidated Framework for Implementation Research (CFIR) and Expert Recommendations for Implementing Change (ERIC) compilation. Methods: We identified stakeholders affected by implementation and conducted a local needs assessment starting 6 months-pre-launch. We then conducted two rapid-cycle evaluations during the first 6 months post-implementation. The CFIR informed survey and interview guide development, data collection, assessment of barriers and facilitators, and selection of ERIC strategies to implement and adapt the intervention. Results: Key themes were: (1) Understanding the hospital's priority to improving tobacco performance metrics was critical in gaining leadership buy-in (CFIR Domain: Outer setting; Construct: External Policy and Incentives). (2) CFIR-based rapid-cycle evaluations allowed us to recognize implementation challenges early and select ERIC strategies clustering into 3 broad categories (conducting needs assessment; developing stakeholder relationships; training and educating stakeholders) to make real-time adaptations, creating an acceptable clinical workflow. (3) Minimizing clinician burden allowed the successful implementation of the TTC service. (4) Demonstrating improved 6-month quit rates and tobacco performance metrics were key to sustaining the program. Conclusions: Rapid-cycle evaluations to gather pre-implementation and early-implementation data, focusing on modifiable barriers and facilitators, allowed us to develop and refine the intervention to improve acceptability, adoption, and sustainability, enabling us to improve tobacco performance metrics in a short timeline. Future directions include spreading rapid-cycle evaluations to promote implementation of inpatient tobacco treatment programs to other settings and assessing long-term sustainability and return on investment of these programs.

RESUMO

BACKGROUND: Thoracic Endometriosis Syndrome (TES) is a rare diagnosis characterized by ectopic endometrial tissue in the chest. Pleural fluid adenosine deaminase (ADA) is thought to be highly specific for tuberculous pleural effusions, particularly when >40 IU/L (international units/liter). RESULTS: A 36-year-old woman from Cameroon (immigrated 10 years ago) with no past medical history presented to the emergency department with increasing abdominal swelling over months found to have on imaging ascites, a left adnexal lesion, a large right-sided pleural effusion and peritoneal studding. Sampling of the pleural fluid revealed dark brown fluid which on analysis was a non-specific exudate with an adenosine deaminase >100. Exploratory laparotomy by gynecology-oncology revealed a large amount of hemorrhagic ascites, multiple endometriotic implants, and a right ovarian endometrioma. Ultimately the patient was taken for video-assisted thoracoscopy (VATS) and decortication. The VATS revealed a diaphragmatic tear was seen suggesting the etiology of the pleural fluid was trans-diaphragmatic passage of blood through the defect. There was no evidence of malignancy or granulomas. Stains and subsequent cultures were negative on all specimens for Mycobacterium tuberculosis. DISCUSSION: Our case demonstrates a rarity of an ADA >100 IU/L due to TES rather than tuberculosis. In conclusion, ADA analysis, as with any lab test, should be interpreted within clinical context as false positives may occur. Several weeks following presentation the patient was discharged without any intrapleural catheter and near complete expansion of the lung. She was started on leuprolide and medroxyprogesterone and has no recurrent effusion or ascites in over two years since initial presentation.

RESUMO

BACKGROUND: To address the burden of tobacco use in underserved populations, our safety net hospital developed a tobacco treatment intervention consisting of an "opt-out" electronic health record-based best practice alert + order set, which triggers consultation to an inpatient tobacco treatment consult (TTC) service for all hospitalized smokers. RESEARCH QUESTION: We sought to understand if the intervention would increase patient-level outcomes (receipt of tobacco treatment during hospitalization and at discharge; 6-month smoking abstinence) and improve hospital-wide performance on tobacco treatment metrics. DESIGN AND METHODS: We conducted two retrospective quasi-experimental analyses to examine effectiveness of the TTC service. Using a pragmatic design and multivariable logistic regression, we compared patient-level outcomes of receipt of nicotine replacement therapy and 6-month quit rates between smokers seen by the service (n = 505) and eligible smokers not seen because of time constraints (n = 680) between July 2016 and December 2016. In addition, we conducted an interrupted time series analysis to examine the effect of the TTC service on hospital-level performance measures, comparing reported Joint Commission measure rates for inpatient (Tob-2) and postdischarge (Tob-3) tobacco treatment preimplementation (January 2015-June 2016) vs postimplementation (July 2016-December 2017) of the intervention. RESULTS: Compared with inpatient smokers not seen by the TTC service, smokers seen by the TTC service had higher odds of receiving nicotine replacement during hospitalization (260 of 505 [51.5%] vs 244 of 680 [35.9%]; adjusted ORs [AOR], 1.93 [95% CI, 1.5-2.45]) and at discharge (164 of 505 [32.5%] vs 84 of 680 [12.4%]; AOR, 3.41 [95% CI, 2.54-4.61]), as well as higher odds of 6-month smoking abstinence (75 of 505 [14.9%] vs 68 of 680 [10%]; AOR, 1.48 [95% CI, 1.03-2.12]). Hospital-wide, the intervention was associated with a change in slope trends for Tob-3 (P < .01), but not for Tob-2. INTERPRETATION: The "opt-out" electronic health record-based TTC service at our large safety net hospital was effective at improving both patient-level outcomes and hospital-level performance metrics, and could be implemented at other safety net hospitals that care for hard-to-reach smokers.

RESUMO

Rationale: Hospitalization is an opportunity to engage smokers who may not seek tobacco treatment. Our safety-net hospital developed and implemented an inpatient intervention consisting of an "opt-out" electronic health record-based Best Practice Alert (BPA)+order-set, designed to trigger referral to the Tobacco Treatment Consult (TTC) service (a team staffed by tobacco treatment specialists) for all hospitalized smokers, regardless of motivation to quit.Objectives: We performed a sequential explanatory mixed-methods study to evaluate the feasibility, acceptability, and adoption of the TTC service.Methods: Among all admissions of adult "current smokers" between July 2016 and June 2017, we calculated the percentage of patients whose clinicians accepted the order-set (through a simple "order" click), thus generating the TTC referral. We then determined the extent of clinician follow-through of TTC recommendations for prescribing nicotine replacement therapy among 1,651 consecutive smokers seen by the TTC service. Finally, we conducted qualitative interviews with inpatient clinicians (n = 25) to understand their rationale for adoption or nonuse of the TTC intervention, including perceived usefulness, barriers to adoption, and strategies to improve the utility of the service.Results: Clinicians accepted the TTC order-set for 4,100 out of 6,598 "current smokers" (62.1%) for whom the BPA fired, typically after initially deferring the BPA. Rates of acceptance significantly differed across clinical services (range: 8% [obstetrics-gynecology] to 82.2% [cardiology]; P < 0.00001). A chart review showed that 43.5% (719/1,651) of the patients seen by the TTC service desired outpatient nicotine replacement therapy, but only half of these patients (48.8%; 351/719) received a discharge prescription from the inpatient team. Clinicians expressed that they valued the TTC service, but that BPA fatigue, time constraints, competing priorities, and poor communication with the TTC service were barriers to using the service and following recommendations. Clinicians suggested strategies to address barriers to the use of tobacco treatment interventions during hospitalization and after discharge.Conclusions: Implementing a large-scale "opt-out" tobacco treatment service for hospitalized smokers at a safety-net hospital is feasible and acceptable, but suffers from inconsistent adoption due to a variety of clinician barriers. System-level changes are needed to increase uptake and sustain inpatient tobacco treatment interventions to promote smoking cessation.

RESUMO

AIMS: Smoking cessation may promote long-term recovery in patients with substance use disorders (SUD). Yet smoking rates remain alarmingly high in this population. Using a sequential explanatory mixed methods approach, we examined smoking rates among hospitalized patients with SUD at a large safety-net hospital, and then characterized factors associated with smoking behaviors both quantitatively and qualitatively. METHOD: We abstracted data from all hospital admissions (7/2016-6/2017) and determined demographics, substance use type, and other characteristics associated with cigarette use among those with SUD. We then conducted semi-structured qualitative interviews with 20 hospitalized SUD smokers. We analyzed transcripts to characterize factors that affect patients' smoking habits, focusing on the constructs of the Health Belief Model. RESULTS: The prevalence of cigarette smoking among hospitalized smokers with SUD was three times higher than those without SUD. Qualitative analyses showed that patients perceived that smoking cigarettes was a less serious concern than other substances. Some patients feared that quitting cigarettes could negatively impact their recovery and perceived that clinicians do not prioritize treating tobacco dependence. Almost all patients with heroin use disorder described how cigarette use potentiated their heroin high. Many SUD patients are turning to vaping and e-cigarettes to quit smoking. CONCLUSION: Hospitalized patients with SUD have disproportionately high smoking rates and perceive multiple barriers to quitting cigarettes. When designing and implementing smoking cessation interventions for hospitalized patients with SUD, policymakers should understand and take into account how patients with SUD perceive smoking-related health risks and how that influences their decision to quit smoking.

RESUMO

Efforts to promote the completion of advance directives implicitly assume that completion rates of these documents, which help ensure care consistent with people's preferences in the event of incapacity, are undesirably low. However, data regarding completion of advance directives in the United States are inconsistent and of variable quality. We systematically reviewed studies published in the period 2011-16 to determine the proportion of US adults with a completed living will, health care power of attorney, or both. Among the 795,909 people in the 150 studies we analyzed, 36.7 percent had completed an advance directive, including 29.3 percent with living wills. These proportions were similar across the years reviewed. Similar proportions of patients with chronic illnesses (38.2 percent) and healthy adults (32.7 percent) had completed advance directives. The findings provide benchmarks for gauging future policies and practices designed to motivate completion of advance directives, particularly among those people most likely to benefit from having these documents on record.

RESUMO

PURPOSE: Cancer genetic services (counseling/testing) are recommended for women diagnosed with breast cancer younger than 45 years old (young breast cancer survivors-YBCS) and at-risk relatives. We present recruitment of YBCS, identification and recruitment of at-risk relatives, and YBCS willingness to contact their cancer-free, female relatives. METHODS: A random sample of 3,000 YBCS, stratified by race (Black vs. White/Other), was identified through a population-based cancer registry and recruited in a randomized trial designed to increase use of cancer genetic services. Baseline demographic, clinical, and family characteristics, and variables associated with the Theory of Planned Behavior (TPB) were assessed as predictors of YBCS' willingness to contact at-risk relatives. RESULTS: The 883 YBCS (33.2% response rate; 40% Black) who returned a survey had 1,875 at-risk relatives and were willing to contact 1,360 (72.5%). From 853 invited at-risk relatives (up to two relatives per YBCS), 442 responded (51.6% response rate). YBCS with larger families, with a previous diagnosis of depression, and motivated to comply with recommendations from family members were likely to contact a greater number of relatives. Black YBCS were more likely to contact younger relatives and those living further than 50 miles compared to White/Other YBCS. CONCLUSION: It is feasible to recruit diverse families at risk for hereditary cancer from a population-based cancer registry. This recruitment approach can be used as a paradigm for harmonizing processes and increasing internal and external validity of large-scale public health genomic initiatives in the era of precision medicine.

RESUMO

BACKGROUND: Evidence suggests that advance directives may improve end-of-life care among seriously ill patients, but improving completion rates remains a challenge. OBJECTIVE: This study tested the influence of increasing the number of options for completing an advance directive among seriously ill patients. METHODOLOGY: Outpatients ( N = 316) receiving hemodialysis across 15 dialysis centers in the Philadelphia region between July 2014 and July 2015 were randomized to receive either the option to complete a brief advance directive form or expanded options including a brief, expanded, or comprehensive form. Patients in both groups could decline to complete an advance directive or take their selected version home. The primary outcome was a returned, completed advance directive. Secondary outcomes included whether patients wanted to complete an advance directive, decision satisfaction, quality of life at 3 months, and patient factors associated with advance directive completion. RESULTS: Although offering more advance directive options was not significantly associated with increased rates of completion (13.1% in the standard group v. 12.2% in the expanded group, P = 0.80), it did significantly increase the proportion of patients who wanted to complete an advance directive and took one home (71.9% in standard v. 85.3% in expanded, P = 0.004). There was no difference in satisfaction ( P = 0.65) or change in quality of life between groups ( P = 0.63). A higher baseline quality of life was independently associated with advance directive completion ( P = 0.006). CONCLUSIONS AND RELEVANCE: These results suggest that although an expanded choice set may initially nudge patients toward completing advance directives without restricting choice, increasing actual completion requires additional interventions that overcome downstream barriers.

RESUMO

Functional imaging studies consistently report abnormal amygdala activity in major depressive disorder (MDD). Neuroanatomical correlates are less clear: imaging studies have produced mixed results on amygdala volume, and postmortem neuroanatomic studies have only examined cell densities in portions of the amygdala or its subregions in MDD. Here, we present a stereological analysis of the volume of, and the total number of, neurons, glia, and neurovascular (pericyte and endothelial) cells in the basolateral amygdala in MDD. Postmortem tissues from 13 subjects with MDD and 10 controls were examined. Sections (~15/subject) taken throughout the rostral-caudal extent of the basolateral amygdala (BLA) were stained for Nissl substance and utilized for stereological estimation of volume and cell numbers. Results indicate that depressed subjects had a larger lateral nucleus than controls and a greater number of total BLA neurovascular cells than controls. There were no differences in the number or density of neurons or glia between depressed and control subjects. These findings present a more detailed picture of BLA cellular anatomy in depression than has previously been available. Further studies are needed to determine whether the greater number of neurovascular cells in depressed subjects may be related to increased amygdala activity in depression.

RESUMO

International Classification of Diseases, 9th Revision (ICD-9) code(s) for neuroblastoma do not exist, preventing identification of these patients in administrative databases. To overcome this challenge, a three-step algorithm, using ICD-9 codes, exclusion criteria, and manual review of chemotherapy billing data, was utilized to assemble a high-risk neuroblastoma cohort (n = 952) from the Pediatric Health Information System (PHIS) Database and validated at a single institution [sensitivity 89.1%; positive predictive value (PPV) 96.1%]. This cohort provides a data source for future comparative effectiveness and clinical epidemiology studies in high-risk neuroblastoma patients.

RESUMO

Neuroimaging consistently reveals smaller hippocampal volume in recurrent or chronic major depressive disorder (MDD). The underlying cellular correlates of the smaller volume are not clearly known. Postmortem tissues from 17 pairs of depressed and control subjects were obtained at autopsy, and informant-based retrospective psychiatric assessment was performed. Formalin-fixed left temporal lobes were sectioned (40 µm), stained for Nissl substance, and every 60th section selected throughout the entire hippocampus. Total volume of the hippocampal formation was calculated, and total numbers of pyramidal neurons (in hippocampal fields CA1, CA2/3, hilus), dentate gyrus (DG) granule cells, and glial cells were estimated stereologically. While hippocampal volume in all MDD subjects was not significantly smaller versus control subjects, in recurrent/chronic MDD, total volume decreased with duration of depressive illness (r = -0.696, p < 0.026). There was no significant difference between MDD and controls in total number or density of pyramidal neurons/granule cells or glial cells in CA1, CA2/3, hilus, or DG. However, CA1 pyramidal neuron density increased with duration of illness in recurrent/chronic MDD (r = 0.840, p < 0.002). Granule cell (r = 0.971, p < 0.002) and glial cell numbers (r = 0.980, p < 0.001) increased with age in those taking antidepressant medication (n = 6). Increasing DG granule cell and glial cell numbers with age in antidepressant-treated subjects may reflect proliferative effects of antidepressant medications. Decreasing total volume and increasing CA1 pyramidal neuron density with duration of illness in recurrent/chronic MDD lends support to the neuropil hypothesis of MDD.

RESUMO

A variety of studies have documented alterations in 5-HT1A receptor binding sites in the brain of subjects with major depressive disorder (MDD). The recently identified transcription factor, nuclear deformed epidermal autoregulatory factor (NUDR/Deaf-1) has been shown to function as a transcriptional modulator of the human 5-HT1A receptor gene. The present study was undertaken to document the regional and cellular localization of NUDR in the human prefrontal cortex and to examine the levels of NUDR and 5-HT1A receptor protein in prefrontal cortex of female and male depressed and control subjects. NUDR immunoreactivity was present in neurons and glia across cortical layers and was co-localized with 5-HT1A receptor immunoreactive neurons. NUDR immunoreactivity as measured by Western blot was significantly decreased in the prefrontal cortex of female depressed subjects (42%, p=0.02) and unchanged in male depressed subjects relative to gender-matched control subjects. Similarly, 5-HT1A receptor protein level was significantly reduced in the prefrontal cortex of female depressed subjects (46%, p=0.03) and unchanged in male depressed subjects compared to gender-matched control subjects. Reduced protein expression of NUDR in the prefrontal cortex of female subjects with MDD may reflect a functional alteration in this transcription factor, which may contribute to the decrease in 5-HT1A receptors observed in the same female subjects with MDD. In addition, the gender-specific alterations in cortical NUDR and 5-HT1A receptor proteins could represent an underlying biological mechanism associated with the higher incidence of depression in women.
