RESUMO

OBJECTIVE: To investigate whether racial, ethnic, and linguistic disparities exist at discharge from an acute inpatient rehabilitation facility (IRF) by examining change in Functional Independence Measure (FIM) scores and discharge destination. DESIGN: This is a retrospective study using our IRF's data from the Uniform Data System for Medical Rehabilitation from 2013-2019. FIM scores and discharge destination were compared between race, language, and ethnic groups, with adjustment for patient characteristics. SETTING: An urban hospital with a level 1 trauma center, comprehensive stroke center, and IRF with Commission on Accreditation of Rehabilitation Facilities (CARF) certification. PARTICIPANTS: 2518 patients admitted to the IRF from 2013-2019 (N=2518). INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: Change in FIM score and discharge destination. RESULTS: After adjusting for covariates, non-White patients and patients with limited English proficiency had significantly lower functional recovery, as measured by smaller changes in FIM scores from IRF admission to discharge. Additionally, both groups were more likely to be discharged home with home health care than to a skilled nursing facility, compared with White and English-speaking patients. Disparities in discharge destination persisted within patients with noncommercial insurance (Medicaid or Medicare) and a stroke diagnosis but not within those who had commercial insurance or a nonstroke diagnosis. CONCLUSIONS: Racial and linguistic disparities were identified within our CARF certified IRF; however, the organization is committed to reducing health care disparities. Next steps will include investigating interventions to reduce disparities.

RESUMO

PURPOSE: Although many integrative therapies exist, studies increasingly demonstrate yoga can help change the negative neuroplastic effects experienced by people living with chronic pain. Despite encouraging findings, a gap exists in accessible yoga programs designed to meet the individual needs of those experiencing limitations from chronic pain. This study evaluated a yoga program designed for people living with chronic pain delivered in a health care setting. Although yoga began as a spiritual practice thousands of years ago, it is now widely practiced for its physical and mental well-being aspects achieved through movement and breathing techniques. DESIGN: This was a piolt study that did not include a control group. METHODS: Twenty-one people with chronic pain participated in an in-person group yoga program for 8 weeks that included an educational program and yoga practice. A prepost design was used to measure effectiveness of the program on pain interference (Brief Pain Inventory), physical function, opioid medication use, overall impression of change in pain, satisfaction with the program, and likelihood of continuation of yoga practice. RESULTS: Data collected from participants demonstrated a decrease in pain interference as measured by the Brief Pain Inventory subscale between pre- and postintervention (5.6 ± 2.2 to 4.0 ± 2.3). In addition, the proportion of respondents with a pain interference rating of severe decreased by 15.4% (38.1% to 22.7%) between the pre- and postintervention time point. On follow-up from a survey 3 months after the completion of the study, more than 25% (N = 5) of participants were still practicing yoga daily. CONCLUSIONS: Despite yoga being practiced for thousands of years, studies evaluating the neural effects of yoga show possible reversal of persistent patterns leading to chronic pain, leading to new interest in an ancient practice. This study helps fill the gap in research findings addressing the benefits of yoga programs designed to meet the needs of people living in chronic pain and provides an accessible option. This program provides pain management nurses an innovative nonpharmacological intervention to consider for people living with chronic pain. CLINICAL IMPLICATIONS: Evidence supporting the use of yoga in the treatment of chronic pain is growing, yet it remains an underutilized approach in a comprehensive treatment plan. Yoga can not only improve self-agency, but also reduces social isolation. Pain management nurses can play an important role in promoting the application of yoga for chronic pain and advocating for yoga programs that are focused on accessibility for people living with pain.

RESUMO

BACKGROUND: The recent increase in opioid misuse and overdose among the Hispanic population signifies the need for an initiative to increase efforts in pain management in the Hispanic population. Yoga is an evidence-based therapeutic intervention that is effective for several pain-associated disorders. However, in the United States, it is primarily taught in English and not always accessible. This quality improvement (QI) project aimed to assess the outcome of implementing a yoga program on pain and quality of life in the Hispanic population. METHODS: Twenty Spanish-speaking community center members participated in a linguistically-tailored yoga program over the course of 10 weeks that included educational, demonstration, and practice videos. Outcome measures of the QI program included changes in pain interference, physical function, opioid medication use, the overall impression of change in pain, satisfaction with the program, and the likelihood of continuation of yoga practice. RESULTS: Data collected from participants (n = 16) after the 10-week period indicated that nearly 60% experienced an improvement in their overall impression of change in pain; their reported likelihood of continuation of yoga practice at home or another location were 6.8 and 7.4, respectively, on a 10-point scale. While pain interference was unaffected, there was an improvement in markers of physical function, including a two-fold improvement in general activity without limitations. The mean average intensity of pain decreased by 33%. CONCLUSION: The use of a linguistically-tailored yoga program improved self-reported overall pain, physical function, average intensity of pain, and initiated an interest in participants in utilizing yoga practice for self-management of pain. This QI project provides results that can be used for further implementation initiatives at other sites and consideration of use in diverse populations.

RESUMO

OBJECTIVES: The purpose of this quality improvement project is to understand the burden of acute care, including inpatient readmission and emergency department (ED) visits, in the month following hospital discharge after stroke. MATERIALS AND METHODS: We identified patients discharged from our hospitals between 2015 and 2018 with any stroke diagnosis who had an unplanned readmission or ED visit within the first month after discharge, and those who had primary care (PC) visits before or after their stroke. Patients were compared regarding demographics, clinical characteristics, and PC visits. Independent predictors of acute care encounters were examined using logistic regression. RESULTS: A total of 166 patients (19%) had an acute care encounter one month after discharge. Eighty-eight (10%) patients were readmitted and 78 (9%) patients had an ED visit. Encounter diagnoses were different between the two groups; inpatient readmission had more frequent acute stroke/TIA and pneumonia/pulmonary indications, while ED visits had more non-specific neurologic symptoms and more frequent cardiovascular complaints. Independent predictors of any acute care encounter and inpatient readmission were younger age, longer length of stay (LOS), and lack of PC visit after discharge. Predictors of ED visits were the same except for LOS. CONCLUSIONS: 30-day acute care encounters after stroke hospitalization are common, affecting 19% of patients and usually occurring in the first week after discharge. Post discharge PC visit was associated with a decreased need for acute care. Efforts should be made to facilitate a PC visit within a week after discharge, especially in high risk patients.

RESUMO

Neutrophil elastase (NE) can be rapidly taken up by tumor cells that lack endogenous NE expression, including breast cancer, which results in cross-presentation of PR1, an NE-derived HLA-A2-restricted peptide that is an immunotherapy target in hematological and solid tumor malignancies. The mechanism of NE uptake, however, remains unknown. Using the mass spectrometry-based approach, we identify neuropilin-1 (NRP1) as a NE receptor that mediates uptake and PR1 cross-presentation in breast cancer cells. We demonstrated that soluble NE is a specific, high-affinity ligand for NRP1 with a calculated Kd of 38.7 nm Furthermore, we showed that NRP1 binds to the RRXR motif in NE. Notably, NRP1 knockdown with interfering RNA or CRISPR-cas9 system and blocking using anti-NRP1 antibody decreased NE uptake and, subsequently, susceptibility to lysis by PR1-specific cytotoxic T cells. Expression of NRP1 in NRP1-deficient cells was sufficient to induce NE uptake. Altogether, because NRP1 is broadly expressed in tumors, our findings suggest a role for this receptor in immunotherapy strategies that target cross-presented antigens.

RESUMO

BACKGROUND AIMS: CD1d-restricted invariant natural killer (iNK) T cells are rare regulatory T cells that may contribute to the immune-regulation in allogeneic stem cell transplantation (ASCT). Here, we sought to develop an effective strategy to expand human iNK T cells for use in cell therapy to prevent graft-versus-host disease (GVHD) in ASCT. METHODS: Human iNK T cells were first enriched from peripheral blood mononuclear cells (PBMCs) using magnetic-activated cell sorting separation, then co-cultured with dendritic cells in the presence of agonist glycolipids, alpha-galactosylceramide, for 2 weeks. RESULTS: The single antigenic stimulation reliably expanded iNK T cells to an average of 2.8 × 107 per 5 × 108 PBMCs in an average purity of 98.8% in 2 weeks (N = 24). The expanded iNK T cells contained a significantly higher level of CD4+ and central memory phenotype (CD45RA-CD62L+) compared with freshly isolated iNK T cells, and maintained their ability to produce both Th-1 (interferon [IFN]γ and tumor necrosis factor [TNF]α) and Th-2 type cytokines (interleukin [IL]-4, IL-5 and IL-13) upon antigenic stimulation or stimulation with Phorbol 12-myristate 13-acetate/ionomycin. Interestingly, expanded iNK T cells were highly autoreactive and produced a Th-2 polarized cytokine production profile after being co-cultured with dendritic cells alone without exogenous agonist glycolipid antigen. Lastly, expanded iNK T cells suppressed conventional T-cell proliferation and ameliorated xenograft GVHD (hazard ratio, 0.1266; P < 0.0001). CONCLUSION: We have demonstrated a feasible approach for obtaining ex vivo expanded, highly enriched human iNK T cells for use in adoptive cell therapy to prevent GVHD in ASCT.

RESUMO

A female in her 70s presented with altered mental status, left eye pain, ophthalmalgia, and diplopia following a fall. Brain MRI demonstrated contrast-enhancing left peri-insular T2 hyperintense changes that was read as possible herpes simplex encephalitis by neuroradiology. Cerebral angiogram revealed a Barrow Type D left sided carotid cavernous fistula. The patient was subsequently treated with endovascular transvenous coil embolization of the left cavernous sinus resulting in complete occlusion of the fistula. The goal of this case is to present a unique case of a carotid cavernous fistula radiologically mimicking herpes simplex encephalitis. Early recognition of carotid cavernous fistula on neuroimaging is important for prompt treatment of symptoms.

RESUMO

We present a unique case of a man presenting with progressive short-term memory deficits over 10+ years who was found to have a large intraventricular cavernoma in the anterior wall of the third ventricle with invasion of medial limbic structures. Identifying intraventricular cavernomas early is crucial to prevent substantial growth and to increase the chance of successful patient outcomes.

RESUMO

OBJECTIVE: The aim of the study is to identify causes and risk factors for potentially preventable readmissions of patients discharged from an inpatient rehabilitation facility. DESIGN: Our hospital billing database was used to identify patients discharged from our inpatient rehabilitation facility between 2013 and 2018 and experienced a potentially preventable readmission within 90 days ( n = 75). Retrospective chart review was completed to obtain clinical data. Of the patients discharged from the inpatient rehabilitation facility who did not experience a potentially preventable readmission, a group of age- and sex-matched controls ( n = 75) was randomly selected. The two study groups were compared using univariate and multivariate analyses. RESULTS: Our study found that individuals who discharged from acute inpatient rehabilitation were more likely to be readmitted with a potentially preventable readmission if they have a greater number of comorbidities, were admitted initially with a spinal cord injury, or have lower admission or discharge Functional Independence Measure motor scores. The most common potentially preventable readmission diagnoses were sepsis, renal failure, respiratory problems, and urinary tract infection. CONCLUSIONS: Identifying patients with the common causes for potentially preventable readmissions, in addition to the noted risk factors, is an important consideration for inpatient rehabilitation discharge planning.

RESUMO

INTRODUCTION: Hispanics living in the United States have higher rates of Epidermal Growth Factor Receptor (EGFR) mutations compared with Non-Hispanic Whites. While this higher incidence is like Asian patients living in the United States, the outcomes for Hispanic patients differ. We looked to compare the variances in mutational profiles between Hispanics and Asians in Los Angeles. PATIENTS AND METHODS: Three hundred ninety three non-small cell lung cancer (NSCLC) patients treated at Los Angeles County + University of Southern California (LAC + USC) Medical Center and Norris Comprehensive Cancer Center who received comprehensive genomic profiling (CGP) were evaluated from July 2017 to August 2020. CGP was done using tissue biopsies (n = 211) from Caris Life Sciences and liquid biopsies (n = 231) from Guardant Health. Multivariate logistic regression evaluated the role of race between Hispanics and Asians. RESULTS: In the Hispanic cohort (n = 90), 50.0% were male, median age of diagnosis was 62, 54.5% were non-smokers, and 85.5% had adenocarcinoma. In Asians (n = 142), 47.5% were male, median age of diagnosis was 65, 59.6% were non-smokers, and 83.8% had adenocarcinoma. Hispanic patients had greater prevalence of Kirsten rat sarcoma virus (KRAS) mutations (odds ratio [OR] 4.42, 95% confidence interval [95% CI]: 1.63-12.83) and lesser prevalence of EGFR mutations (OR 0.31, 95% CI: 0.16-0.59). There were a greater proportion of Hispanic smokers with KRAS mutations (14/41; 34.1%) than Asian smokers (4/58; 6.9%). CONCLUSION: We saw a greater percentage of Hispanics with KRAS mutations despite similar smoking percentages along with a greater percentage of Asians with EGFR mutations. This study shows that ethnic and racial backgrounds of the patient can influence the effects of potentially carcinogenic exposures leading to variances of mutation frequency of NSCLC among different ethnicities.

RESUMO

OBJECTIVE: The aim of the study was to identify causes for readmission to acute care of patients admitted to inpatient rehabilitation facility after stroke. DESIGN: The institutional Uniform Data System for Medical Rehabilitation database was used to identify stroke patients who experienced readmission to acute care and an equal number of age-/sex-matched group of patients who successfully completed their inpatient rehabilitation facility stay during 2005-2018. Retrospective chart review was used to extract clinical data. The two study groups were compared using univariate and multivariate analyses. RESULTS: The rate of readmission to acute care was 4.7% (n = 89; age = 65 ± 14 yrs; 37% female; 65% White; 73% ischemic stroke). The most common indications for transfer were neurological (31%) and cardiovascular (28%). Compared with control group, the readmission to acute care group had statistically higher rates of comorbid conditions, lower median (interquartile range) Functional Independence Measure score on inpatient rehabilitation facility admission (55 [37-65] vs. 64 [51-78], P < 0.001), and a higher rate of sedative/hypnotic prescription (82% vs. 23%, P < 0.001). CONCLUSIONS: Readmission to acute care is not common in our cohort. Patients who experienced readmission to acute care had higher medical complexity and were prescribed more sedative/hypnotic medications than the control group. Practitioners should be vigilant in patients who meet these criteria.

RESUMO

Problems within the Pathology fellowship application process in the US have been recognized and reported for years. Recently, members of the Graduate Medical Education Committee (GMEC) of the Association of Pathology Chairs (APC) and collaborators collected survey data from the residents themselves and the fellowship programs, as represented by both the fellowship program directors (members of the Fellowship Directors Ad Hoc Committee, FDAHC) and the program administrators (members of the Graduate Medical Education Administrators Section, GMEAS). These data are presented and discussed, and potential steps to resolve some of the problems around fellowship applications in pathology are presented.

RESUMO

BACKGROUND: Accurate medical image interpretation is an essential proficiency for multiple medical specialties, including dermatologists and primary care providers. A dermatoscope, a ×10-×20 magnifying lens paired with a light source, enables enhanced visualization of skin cancer structures beyond standard visual inspection. Skilled interpretation of dermoscopic images improves diagnostic accuracy for skin cancer. OBJECTIVE: Design and validation of Cutaneous Neoplasm Diagnostic Self-Efficacy Instrument (CNDSEI)-a new tool to assess dermatology residents' confidence in dermoscopic diagnosis of skin tumors. METHODS: In the 2018-2019 academic year, the authors administered the CNDSEI and the Long Dermoscopy Assessment (LDA), to measure dermoscopic image interpretation accuracy, to residents in 9 dermatology residency programs prior to dermoscopy educational intervention exposure. The authors conducted CNDSEI item analysis with inspection of response distribution histograms, assessed internal reliability using Cronbach's coefficient alpha (α) and construct validity by comparing baseline CNDSEI and LDA results for corresponding lesions with one-way analysis of variance (ANOVA). RESULTS: At baseline, residents respectively demonstrated significantly higher and lower CNDSEI scores for correctly and incorrectly diagnosed lesions on the LDA (P = 0.001). The internal consistency reliability of CNDSEI responses for the majority (13/15) of the lesion types was excellent (α ≥ 0.9) or good (0.8≥ α <0.9). CONCLUSIONS: The CNDSEI pilot established that the tool reliably measures user dermoscopic image interpretation confidence and that self-efficacy correlates with diagnostic accuracy. Precise alignment of medical image diagnostic performance and the self-efficacy instrument content offers opportunity for construct validation of novel medical image interpretation self-efficacy instruments.

RESUMO

Introduction: Low back pain is a leading disability worldwide; however, it is not often the result of a serious underlying condition such as a tumor. As a result, diagnosis of a serious underlying cause of low back pain may be delayed, such as in this case. Case presentation: We describe a case of a man presenting with low back pain, who was eventually diagnosed with solitary bone plasmacytoma (SBP) causing spinal cord compression from approximately T7-T9. The patient was classified as T8 ASIA C-Incomplete Paraplegia. He underwent an emergency T7-T9 open posterior laminectomy and resection of the epidural mass/tumor. Following an intensive course of rehabilitation treatment, the patient progressed to ASIA D. Discussion: Although SBP of the spine is rare, back or neck pain is a common initial presentation. This case is unique in that we provide a detailed description of both medical and rehabilitation diagnosis and treatment. We also suggest that persistent back pain warrants complete MRI spinal imaging to provide proper diagnosis and prompt treatment for cases with a serious underlying condition.

RESUMO

Longitudinal myelitis secondary to an acute flare of systemic lupus erythematosus has been reported in the literature. There have been few published cases of complete functional recovery in patients with systemic lupus erythematosus-related longitudinal myelitis (systemic lupus erythematosus-related longitudinal myelitis). Of those cases, none have described in detail the rehabilitation course of treatment. In the current case, intensive rehabilitation was coupled with aggressive pharmaceutical treatment resulting in almost full functional recovery. A 23-yr-old African American woman with a history of systemic lupus erythematosus was originally admitted as an inpatient for flank pain. Overnight, she progressed rapidly to complete flaccid paraplegia classified as T3 American Spinal Injury Association Impairment Scale A based on the International Standards for Neurological Classification of Spinal Cord Injury. Throughout the next year, she participated in acute inpatient rehabilitation, followed by outpatient rehabilitation (physical, occupational, and aquatic therapies). A year after her initial hospital admission, she progressed to full community ambulation T3 American Spinal Injury Association Impairment Scale D. This case illustrates the importance of proper medical treatment and a comprehensive rehabilitation program, which improved functional outcomes for a patient with a complete spinal cord injury due to systemic lupus erythematosus-related longitudinal myelitis.

RESUMO

Vanishing bile duct syndrome (VBDS) is a rare entity of acquired disorders resulting in cholestasis secondary to progressive destruction of intrahepatic bile ducts. The syndrome has been described in the setting of autoimmune disorders, medication toxicities, genetic disorders, infectious etiologies, and in rare cases, neoplastic processes. There are no known case reports of VBDS in the setting of uterine malignancy. We present a case of VBDS in a patient with underlying uterine cancer complicated by paraneoplastic systemic sclerosis.

RESUMO

Despite substantial advances in the treatment of acute myeloid leukemia (AML), only 30% of patients survive more than 5 years. Therefore, new therapeutics are much needed. Here, we present a novel therapeutic strategy targeting PR1, an HLA-A2 restricted myeloid leukemia antigen. Previously, we have developed and characterized a novel T-cell receptor-like monoclonal antibody (8F4) that targets PR1/HLA-A2 and eliminates AML xenografts by antibody-dependent cellular cytotoxicity (ADCC). To improve the potency of 8F4, we adopted a strategy to link T-cell cytotoxicity with a bi-specific T-cell-engaging antibody that binds PR1/HLA-A2 on leukemia and CD3 on neighboring T-cells. The 8F4 bi-specific antibody maintained high affinity and specific binding to PR1/HLA-A2 comparable to parent 8F4 antibody, shown by flow cytometry and Bio-Layer Interferometry. In addition, 8F4 bi-specific antibody activated donor T-cells in the presence of HLA-A2+ primary AML blasts and cell lines in a dose dependent manner. Importantly, activated T-cells lysed HLA-A2+ primary AML blasts and cell lines after addition of 8F4 bi-specific antibody. In conclusion, our studies demonstrate the therapeutic potential of a novel bi-specific antibody targeting the PR1/HLA-A2 leukemia-associated antigen, justifying further clinical development of this strategy.

RESUMO

Abstract Six sample preparation procedures were evaluated for selective extraction of Cr(VI) from commercial samples of chromium oxide green (Cr2O3) pigments prior to formation of its diphenylcarbazone complex [CrDPCO]- for determination by visible spectrophotometry: (I) water-soluble chromium; (II) EPA method 3060A without Mg2+; (III) EPA method 3060A with Mg2+; (IV) Na3PO4 based extraction; (V) method IRSA16 based on acidic extraction and; (VI) Na2CO3 based extraction. Evaluation of the influence of concomitant Cr(III) ions, time and stability of the [CrDPCO]- complex was investigated. Recoveries of soluble and insoluble Cr(VI) species were 86% and 80%, respectively, using procedure (VI). Direct calibration against aqueous standards prepared in the extraction medium was successful for Cr(VI) in the concentration range 0.05-1.50 μg L-1. Limits of detection and quantitation were 0.3 µg g-1 and 1.0 µg g-1, respectively, for 250 mg subsamples/25 mL. Procedure (VI) was applied to the analysis of four commercial samples of Cr2O3 pigments, three determined to have Cr(VI) within compliance limits below 1.0 µg g-1, but one at 16.6 ± 0.6 µg g-1, prohibiting use of this pigment in cosmetic formulations. This sample was conveniently employed to evaluate the accuracy of the method. The recommended procedure is simple and accurate and has been adopted by Tecpar's laboratory of Parana Institute of Technology (Curitiba, Brazil).
