RESUMEN

Sickle cell disease (SCD) is a hemoglobin disorder and the most common genetic disorder that affects 100,000 Americans and millions worldwide. Adults living with SCD have pain so severe that it often requires opioids to keep it in control. Depression is a major global public health concern associated with an increased risk in chronic medical disorders, including in adults living with sickle cell disease (SCD). A strong relationship exists between suicidal ideation, suicide attempts, and depression. Researchers enrolling adults living with SCD in pragmatic clinical trials are obligated to design their methods to deliberately monitor and respond to symptoms related to depression and suicidal ideation. This will offer increased protection for their participants and help clinical investigators meet their fiduciary duties. This article presents a review of this sociotechnical milieu that highlights, analyzes, and offers recommendations to address ethical considerations in the development of protocols, procedures, and monitoring activities related to suicidality in depressed patients in a pragmatic clinical trial.

RESUMEN

BACKGROUND: Sickle cell disease (SCD) is a diverse group of blood disorders with significant global disease burden. Contemporary interest in the underlying inflammatory paradigm of SCD has emphasized the role of the neutrophil-lymphocyte ratio (NLR) as a prognostic inflammatory marker. METHODS: We retrospectively reviewed 268 hospitalized patients with SCDs of different genotypes (HbSS, HbSß0 thalassemia, HbSß+ thalassemia, and HbSC), totaling 3329 hospital admissions over a 10-year period. Patients were stratified into SS/Sß0 and Sß+/SC groups for statistical analysis of parameters collected at steady state and at hospital admission. RESULTS: At steady state, per unit increase of hemoglobin values was associated with reduced odds of ≥ 2 hospital admissions per year in SS/Sß0 and Sß+/SC groups; per unit increase in platelet count and white blood cell count was associated with increased odds only in the SS/Sß0 group. The NLR had no association in either group. During admission, a cutoff of NLR = 3.5 discerned infection with a sensitivity of 60% and specificity of 57%. Performance improved when excluding patients on outpatient hydroxyurea therapy (cutoff of NLR = 3.5; sensitivity of 68% and specificity of 64%). CONCLUSION: This study supports the utility of NLR as an accessible adjunctive clinical tool in SCD prognostication.

RESUMEN

Background: People with sickle cell disease frequently use complementary and integrative therapies to cope with their pain, yet few studies have evaluated their effectiveness. The 3-arm, 3-site pragmatic Hybrid Effectiveness-implementation Trial of Guided Relaxation and Acupuncture for Chronic Sickle Cell Disease Pain (GRACE) has 3 priorities: (1) evaluate guided relaxation and acupuncture to improve pain control; (2) determine the most appropriate and effective treatment sequence for any given patient based on their unique characteristics; and (3) describe the processes and structures required to implement guided relaxation and acupuncture within health care systems. Methods: Participants (N = 366) are being recruited and randomized 1:1:1 to one of 2 intervention groups or usual care. The acupuncture intervention group receives 10 sessions over approximately 5 weeks. The guided relaxation intervention group receives access to video sessions ranging from 2 to 20 min each viewed daily over 5 weeks. The usual care group receives the standard of clinical care for sickle cell disease. Participants are re-randomized at 6 weeks depending on their pain impact score. Assessments occur at 6 weeks, 12 weeks, and 24 weeks. The primary outcome is the change in pain impact score and secondary measures include opioid use, anxiety, depression, sleep, pain catastrophizing, substance use, global impression of change, constipation, and hospitalizations. The GRACE study uses the Consolidated Framework for Implementation Research to plan, execute, and evaluate the associated implementation processes. Conclusion: The results from GRACE will represent a critical step toward improving management of pain affecting patients with sickle cell disease.ClinicalTrials.gov Identifier: NCT04906447.

RESUMEN

BACKGROUND: This paper describes the research protocol for a randomized controlled trial of a self-management intervention for adults diagnosed with sickle cell disease (SCD). People living with SCD experience lifelong recurrent episodes of acute and chronic pain, which are exacerbated by stress. OBJECTIVE: This study aims to decrease stress and improve SCD pain control with reduced opioid use through an intervention with self-management relaxation exercises, named You Cope, We Support (YCWS). Building on our previous findings from formative studies, this study is designed to test the efficacy of YCWS on stress intensity, pain intensity, and opioid use in adults with SCD. METHODS: A randomized controlled trial of the short-term (8 weeks) and long-term (6 months) effects of YCWS on stress, pain, and opioid use will be conducted with 170 adults with SCD. Patients will be randomized based on 1:1 ratio (stratified on pain intensity [≤5 or >5]) to be either in the experimental (self-monitoring of outcomes, alerts or reminders, and use of YCWS [relaxation and distraction exercises and support]) or control (self-monitoring of outcomes and alerts or reminders) group. Patients will be asked to report outcomes daily. During weeks 1 to 8, patients in both groups will receive system-generated alerts or reminders via phone call, text, or email to facilitate data entry (both groups) and intervention use support (experimental). If the participant does not enter data after 24 hours, the study support staff will contact them for data entry troubleshooting (both groups) and YCWS use (experimental). We will time stamp and track patients' web-based activities to understand the study context and conduct exit interviews on the acceptability of system-generated and staff support. This study was approved by our institutional review board. RESULTS: This study was funded by the National Institute of Nursing Research of the National Institutes of Health in 2020. The study began in March 2021 and will be completed in June 2025. As of April 2022, we have enrolled 45.9% (78/170) of patients. We will analyze the data using mixed effects regression models (short term and long term) to account for the repeated measurements over time and use machine learning to construct and evaluate prediction models. Owing to the COVID-19 pandemic, the study was modified to allow for mail-in consent process, internet-based consent process via email or Zoom videoconference, devices delivered by FedEx, and training via Zoom videoconference. CONCLUSIONS: We expect the intervention group to report reductions in pain intensity (primary outcome; 0-10 scale) and in stress intensity (0-10 scale) and opioid use (Wisepill event medication monitoring system), which are secondary outcomes. Our study will contribute to advancing the use of nonopioid therapy such as guided relaxation and distraction techniques for managing SCD pain.

RESUMEN

Background It is unknown whether nurses' knowledge about pain among patients with sickle cell disease (SCD) reflects the current standard of care. The authors evaluated changes in nurses' knowledge and simulated practice behavior after a continuing education program. Method Inpatient nurses completed an e-learning program on SCD pain; a pretest and a posttest with the same 10 questions; and two patient cases with four pain intervention options at the posttest. Results On the pretest, the mean percentage of correct answers was 83% (SD = 13%). The mean percentage of correct answers increased by 12% (p < .0001) on the posttest. For the first simulated patient case, 100% (n = 31) of the nurses selected an appropriate pain intervention option based on the patient-reported pain score. For the second simulated patient case, 84% (n = 26) did so. Conclusion Increased knowledge does not always translate into simulated practice change. The reasons for this are unknown, but they could include implicit bias from exposure to patients who have high use of acute care, although the minority of patients with SCD fit this description.

RESUMEN

Acquired von Willebrand syndrome is a rare bleeding disorder characterised by a later age of onset without a personal or family history of bleeding diathesis. It is vital to discern acquired von Willebrand syndrome from inherited von Willebrand disease and other acquired bleeding disorders as management differs significantly. Acquired von Willebrand syndrome is usually secondary to an underlying disorder such as lymphoproliferative disorder, myeloproliferative neoplasm, solid tumour, cardiovascular disorder, autoimmune disorders or hypothyroidism. Diagnosis is often delayed with a significant risk of morbidity and even mortality. Here we present a case of a 74-year-old man with an acquired bleeding disorder and work up suggestive of acquired von Willebrand syndrome secondary to immunoglobulin G kappa multiple myeloma. He was treated successfully with intravenous immunoglobulin, von Willebrand Factor/Coagulation Factor VIII Complex (human), myeloma directed chemotherapy and autologous stem cell transplantation. We also discuss the management strategies that are largely based on retrospective studies and case reports.

RESUMEN

BACKGROUND: The experiences of African American adult patients before, during, and after acute care utilization are not well characterized for individuals with sickle cell disease (SCD) or cancer. OBJECTIVE: To describe the experiences of African Americans with SCD or cancer before, during, and after hospitalization for pain control. METHODS: We conducted a qualitative study among African American participants with SCD (n = 15; 11 male; mean age, 32.7 ± 10.9 years; mean pain intensity, 7.8 ± 2.6) or cancer (n = 15; 7 male; mean age, 53.7 ± 15.2 years; mean pain intensity, 4.9 ± 3.7). Participants completed demographic questions and pain intensity using PAINReportIt and responded to a 7-item open-ended interview, which was recorded and transcribed verbatim. We used content analysis to identify themes in the participants' responses. RESULTS: Themes identified included reason for admission, hospital experiences, and discharge expectations. Pain was the primary reason for admission for participants with SCD (n = 15) and for most participants with cancer (n = 10). Participants of both groups indicated that they experienced delayed treatment and a lack of communication. Participants with SCD also reported accusations of drug-seeking behavior, perceived mistreatment, and feeling of not being heard or believed. Participants from both groups verbalized concerns about well-being after discharge and hopeful expectations. CONCLUSIONS: Race-concordant participants with SCD but not with cancer communicated perceived bias from healthcare providers. IMPLICATIONS FOR PRACTICE: Practice change interventions are needed to improve patient-provider interactions, reduce implicit bias, and increase mutual trust, as well as facilitate more effective pain control, especially for those who with SCD.

RESUMEN

Little is known about the effects of self-managed relaxation interventions on pain, stress, and autonomic responses in patients with sickle cell disease (SCD). This pre-post randomized controlled pilot study was conducted to determine the feasibility of using computer tablets for relaxation intervention delivery; acceptability of study procedures; and intervention effects on pain, stress, and indicators of relaxation. The 30 research participants ranged in age from 22 years to 59 years. All were African American; 53% were male. They were randomized to an experimental group that watched a relaxation video or a control group that discussed their disease. All participants completed the study, indicating feasibility. Acceptability rates were also high. Data were obtained for the intervention's immediate effect on pain, stress, respiration, pulse, finger skin temperature, and self-reported relaxation. These preliminary findings will guide future, higher-powered studies to determine the intervention's efficacy and mechanism in SCD.The ClinicalTrials.gov Identifier: NCT02729363.

RESUMEN

Human malaria has arguably affected more of human history than any other pathogen. Pregnant women have a higher risk of developing severe malaria as well as the risk of severe complications. We present a case of severe malaria in a pregnant patient from sub-Saharan Africa who was treated successfully with artesunate. A 28-year-old Nigerian woman with a 20-week intrauterine pregnancy presented with a five-day history of fever and diffuse joint pains. Evaluation of peripheral thin blood smear demonstrated a parasitemia of 9.8%. The patient was admitted to the intensive care unit, and oral clindamycin/quinine was initiated until intravenous artesunate was obtained. The patient completed four doses of IV artesunate, and after the 4th dose of artesunate, no blood parasites were seen on peripheral smear. The patient was discharged home and, upon clinic follow-up, did not have any further complications associated with either her disease or therapy. A review on the treatment of severe malaria in all trimesters of pregnancy supports the WHO recommendation for intravenous artesunate as the drug of choice. This case illustrates the importance of recognizing malaria in pregnant women from endemic countries and shows that artesunate compounds can be used safely in pregnancy, particularly with high parasitemia.

RESUMEN

Lung transplantation surgery often relies on the use of intraoperative extracorporeal membrane oxygenation (ECMO) and necessitates the need for high dose anticoagulation. Heparin induced thrombocytopenia complicates intraoperative anticoagulation management during lung transplant surgery requiring ECMO. Though other anticoagulants such as argatroban and bivalrudin are utilized for the treatment of Heparin Induced Thrombocytopenia (HIT), the lack of reversal agents makes it difficult to use these agents intraoperatively in cases with high bleeding risk. This is especially true in patients with end stage fibrotic lung disease with calcified mediastinal lymphadenopathy and pulmonary hypertension undergoing lung transplantation. Here we describe a case of HIT in a patient with Sarcoidosis listed for lung transplant who was treated with Therapeutic Plasma Exchange and Intravenous Immune globulin preoperatively and successfully underwent lung transplantation with the use of intraoperative venoarterial ECMO and heparin anticoagulation.

RESUMEN

A 46-year-old man presented with splenomegaly, abdominal adenopathy and profoundly elevated prothrombin time and partial thromboplastin time. He was diagnosed with marginal zone lymphoma (MZL) and small lymphocytic lymphoma, and the abnormal coagulation studies were secondary to the presence of a lupus anticoagulant. Optimal upfront therapy for MZL has not been established, and the incidence of antiphospholipid antibodies (APLA) in this patient population is rare. Following treatment with six cycles of bendamustine and rituximab with 2 years of rituximab maintenance, our patient remained in remission and his coagulation studies normalised. This report describes a case of successful treatment of APLA associated with MZL that resolved after treatment of the lymphoma.

RESUMEN

BACKGROUND: Delayed hemolytic transfusion reaction (DHTR) with hyperhemolysis is a potentially fatal complication resulting from alloimmunization that can cause severe hemolysis of both transfused and intrinsic red blood cells (RBCs). Patients with sickle cell disease often receive multiple RBC units during their lifetime and thus are likely to develop alloantibodies that increase the risk for DHTR. Treatment to decrease hemolysis includes intravenous immunoglobulin (IVIG), steroids, eculizumab, rituximab, and plasmapheresis in addition to erythropoietin (EPO), intravenous (IV) iron, vitamin B12, and folate to support erythropoiesis. RBC transfusion is preferably avoided in DHTR due to an increased risk of exacerbating the hemolysis. CASE REPORT: We report a rare case of anti-N and anti-Doa immunoglobulin (Ig)G alloantibody-mediated life-threatening DHTR with hyperhemolysis in a patient with hemoglobin SS after RBC transfusion for acute chest syndrome who was successfully treated with eculizumab and HBOC-201 (Hemopure) in addition to steroids, IVIG, EPO, IV iron, and vitamin B12. HBOC-201 (Hemopure) was successfully used as a RBC alternative in this patient. CONCLUSION: Anti-N and anti-Doa IgG alloantibodies can rarely cause severe life-threatening DHTR with hyperhemolysis. HBOC-201 (Hemopure) can be a lifesaving alternative in this scenario. Our report also supports the use of eculizumab in DHTR; however, prospective studies are needed to determine the appropriate dose and sequence of eculizumab administration.

RESUMEN

To evaluate the pain coping strategies of patients with sickle cell disease (SCD) who experience healthcare injustice from either physicians or nurses during medical visits for pain management. It is unknown how patients' coping with pain relates to their experiences of healthcare injustice from physicians or nurses. This descriptive comparative study included adult outpatients with SCD who completed the PAINReportIt®, Healthcare Justice Questionnaire©, and Coping Strategies Questionnaire-SCD. Data were analyzed using independent t tests. Frequent coping strategies of patients who experienced healthcare justice from physicians were praying-hoping and from nurses were praying-hoping, calming self-statements, diverting attention, and increasing behavioral activity. In contrast, frequent coping strategies of patients who experienced healthcare injustice from physicians were catastrophizing and isolation and from nurses were isolation. Patients who experienced healthcare justice used different sets of pain coping strategies than those who experienced healthcare injustice during medical visits for pain management.

RESUMEN

Venous thromboembolism (VTE) results in significant morbidity and mortality. The prevention and treatment of VTE is managed with anticoagulant therapy, historically parenteral anticoagulants such as unfractionated heparin, low molecular weight heparin, and fondaparinux, and oral vitamin K antagonists such as warfarin. In the last few years, several target-specific oral anticoagulants have been developed, including the direct thrombin inhibitor dabigatran and anti-Xa inhibitors rivaroxaban, apixaban, and edoxaban. The target-specific oral anticoagulants have proven to be noninferior to vitamin K antagonists and heparins in the prevention and treatment of VTE. This review will focus on the pharmacology, clinical trial data, and laboratory assessment of apixaban. Moreover, perioperative management, use in special populations, and management of bleeding complications in patients taking apixaban for the prevention and treatment of VTE will also be discussed.
