RESUMO

INTRODUCTIONClosing the TB diagnostic gap is an urgent priority, for which non-sputum-based tests are needed. We evaluated the diagnostic accuracy of Aeonose, an exhaled breath test (EBT), as a TB triage test.METHODSPatients with cough or TB risk factors admitted to a tertiary hospital in Lima, Peru, were prospectively enrolled and underwent EBT. We evaluated EBT sensitivity and specificity for diagnosing pulmonary TB using culture and Xpert as primary and secondary reference standards and conducted stratified analyses based on risk factors.RESULTSEBT sensitivity was 85% (95% CI 72.9-93.4), and specificity was 51% (95% CI 46.0-56.6) in the training cohort (n = 417). EBT sensitivity was 70% (95% CI 47.1-86.8), and specificity was 54% (95% CI 44.8-63.6) in the validation cohort (n = 139) using the culture reference standard, with higher sensitivity (78%) when using the Xpert reference standard (n = 156). Sensitivity (60%) and specificity (48%) were lower when patients with prior TB were included. In a subset of participants randomly selected for interviews, 94% (15/16) preferred EBT to sputum-based testing.CONCLUSIONSEBT had moderate sensitivity and low specificity as a TB triage test in this hospitalised cohort with cough or risk factors. Diagnostic accuracy was lower in people with prior TB..

RESUMO

In the United States (US), tuberculosis elimination strategies include scaling up latent tuberculosis infection (LTBI) diagnosis and treatment for persons at risk of progression to tuberculosis disease. The Massachusetts Department of Public Health partnered with Lynn Community Health Center to provide care to patients with LTBI who were born outside the US. The electronic health record was modified to facilitate collection of data elements for public health assessment of the LTBI care cascade. Among health center patients born outside the US, testing for tuberculosis infection increased by over 190%. From October 1, 2016 to March 21, 2019, 8827 patients were screened and 1368 (15.5%) were diagnosed with LTBI. Using the electronic health record, we documented treatment completion for 645/1368 (47.1%) patients. The greatest drop-offs occurred between testing for TB infection and clinical evaluation after a positive test (24.3%) and between the recommendation for LTBI treatment and completion of a treatment course (22.8%). Tuberculosis care delivery was embedded in the primary care medical home, bringing patient-centered care to those at high risk for loss to follow up. The partnership between public health and the community health center promoted quality improvement.

RESUMO

Patients undergoing allogeneic hematopoietic cell transplantation (HCT) are at risk for high morbidity and mortality. Advance directives (AD) allow patients to express wishes regarding their care at the end of life, but these are not completed in the majority of patients undergoing HCT, with only 44% of deceased allogeneic HCT recipients at this institution completing an AD in the past decade. Increasing the AD completion rate can improve the quality of care for allogeneic HCT recipients. Our objective was to evaluate whether an alternative AD instrument can increase AD completion rate and patient satisfaction. We conducted a prospective, randomized controlled study of the traditional California AD versus a novel Letter AD, the Stanford What Matters Most Letter, in adult allogeneic HCT recipients. Patients age ≥18 years undergoing first allogeneic HCT at Stanford University were eligible. Prior to HCT conditioning, enrolled patients were assigned at random to complete either the traditional AD or the Letter AD. The primary endpoint was AD completion. The chi-square test was used to compare the AD completion rate between arms. The Wilcoxon rank-sum test was used to compare uncertainty, satisfaction with decision making, and satisfaction with the AD. Of the 212 patients who were eligible, 126 (59.4%) were enrolled and randomized. The mean age was 53.7 years, 57 (45.2%) were female, and 74 (58.7%) were non-Hispanic white. The overall AD completion rate was 71.4% and did not differ between the traditional and Letter AD arms (70.3% versus 72.6%; P = .78). Of those who completed the Letter AD, 66.7%, 42.2%, and 46.7% of patients wished to die gently/naturally, at home, and/or with hospice, respectively. In the traditional AD arm, 60.0% wished to not prolong life if recovery was unlikely. Opinion surveys did not find differences in levels of satisfaction between the traditional AD and Letter AD. Completion rates of AD on this study were high (71.4%) compared with historically reported completion rates and did not significantly differ based on AD version.

RESUMO

The high cost of healthcare in the United States has not been consistently associated with improved health outcomes or quality of care, necessitating a focus on value-based care. We identified busulfan dosing frequency during allogeneic hematopoietic cell transplantation (HCT) conditioning as a potential target for optimization. To improve patient convenience and to decrease the cost of busulfan-based conditioning regimens, our institution changed busulfan dose frequency from every 6 hours (q6h) to once-daily (q24h). We compared costs and patient outcomes between these 2 dosing schedules. In June 2017, our institution transitioned from q6h to q24h busulfan dosing. We compared patients who received busulfan/cyclophosphamide conditioning regimens (BU/CY) for allogeneic HCT in the year before the dosing change (q6h cohort) and those who did so in the year after the dosing change (q24h cohort). The primary outcomes were differences in cost, day +90 mortality, and day +90 relapse. Between June 1, 2016, and June 1, 2018, 104 patients (median age 49 years; range, 20 to 63 years) received BU/CY before allogeneic HCT. Fifty-nine patients (57%) received q6h busulfan and 45 (43%) received q24h busulfan. There were fewer men in the q24h busulfan cohort compared with the q6h busulfan cohort (42% versus 64%; P = .024), but there were no other significant differences between the groups. There was an average annual cost savings of $19,990 per patient with q24h busulfan compared with q6h busulfan, and an annual busulfan cost savings of $899,550. There was a significantly lower day +90 mortality in the q24h busulfan cohort compared to the q6h busulfan cohort (0% versus 10%; P = .028). There were no significant differences in relapse at day +90 or in hospital length of stay. Our data indicate that i.v. busulfan dosing for allogeneic HCT conditioning is a target for improved value-based care. At our institution, patients who received q24h busulfan dosing had similar or superior outcomes compared with those receiving q6h dosing, with an average annual cost reduction of $19,990 per patient and an overall annual reduction in busulfan cost of approximately $900,000. These data support the adoption of q24h i.v. busulfan dosing as a standard of care to improve value-based care in allogeneic HCT.

RESUMO

Drug-resistant tuberculosis (DR-TB) represents a major programmatic challenge at the national and global levels. Only ∼30% of patients with multidrug-resistant TB (MDR-TB) were diagnosed, and ∼25% were initiated on treatment for MDR-TB in 2016. Increasing evidence now points towards primary transmission of DR-TB, rather than inadequate treatment, as the main driver of the DR-TB epidemic. The cornerstone of DR-TB transmission prevention should be earlier diagnosis and prompt initiation of effective treatment for all patients with DR-TB. Despite the extensive scale-up of Xpert® MTB/RIF testing, major implementation barriers continue to limit its impact. Although there is longstanding evidence in support of the rapid impact of treatment on patient infectiousness, delays in the initiation of effective DR-TB treatment persist, resulting in ongoing transmission. However, it is also imperative to address the burden of latent drug-resistant tuberculous infection because it is estimated that many DR-TB patients will become infectious before seeking care and encounter various diagnostic delays before treatment. Addressing latent DR-TB primarily consists of identifying, treating and following the contacts of patients with MDR-TB, typically through household contact evaluation. Adjunctive measures, such as improved ventilation and use of germicidal ultraviolet technology can further reduce TB transmission in high-risk congregate settings. Although many gaps remain in our biological understanding of TB transmission, implementation barriers to early diagnosis and rapid initiation of effective DR-TB treatment can and must be overcome if we are to impact DR-TB incidence in the short and long term.

RESUMO

SETTING: The tuberculous infection control strategy, FAST (Find cases Actively, Separate safely and Treat effectively), recommends prompt initiation of likely effective anti-tuberculosis treatment informed by Xpert® MTB/RIF results.OBJECTIVE: To describe FAST implementation at Quang Nam Provincial TB and Lung Disease Hospital (QNH), Tam Ky, Viet Nam, using time to initiation of effective TB treatment as a process measure. DESIGN: Hospital logs were used to calculate the time to likely effective treatment in patients with pulmonary TB (PTB) hospitalised during the study period. RESULTS: Between 1 January and 31 December 2016, of 858 patients treated for PTB, 493 (57.5%) received likely effective treatment. The median time to likely effective treatment was 3 days (interquartile range 2.0-6.0), with 213 (43.2%) patients receiving likely effective treatment within 2 days. Of 81 patients receiving likely effective treatment for drug-susceptible TB with a positive Xpert result as their initial in-patient diagnostic test, 64 (79.0%) received likely effective treatment within 2 days compared with 10 (5.7%) who were initially smear-negative then found to be Xpert-positive (P < 0.0001). CONCLUSIONS: A 'time to' process measure of the FAST tuberculous infection control strategy indicates delays in the initiation of likely effective anti-tuberculosis treatment in a resource-limited hospital. Expanding access to Xpert may speed time to likely effective treatment.

RESUMO

INTRODUCTION: This study examines caregiver quality of life (CQOL) 3-26 years after autologous hematopoietic cell transplantation (HCT) for patients with lymphoma. Using a framework that views the patient-caregiver dyad as a system of mutual influence, we argue that CQOL is associated with survivor functional health status and sense of personal control. METHODS: Ninety-nine autologous HCT survivor-caregiver dyads participated. CQOL was measured using the Caregiver Quality of Life Scale-Cancer. Survivor functional health status was assessed using the Functional Assessment of Cancer Therapy-General. Sense of control was examined using an instrument from the MIDUS II study. Clinical measures were collected from medical records. RESULTS: After controlling for sociodemographic and clinical covariates, caregivers with higher sense of control had higher CQOL. Poorer survivor functional health was associated with lower CQOL but only when the survivor reported low personal control. When the survivor reported high personal control, functional health was not a factor. Lower CQOL was observed for younger and more educated caregivers. In contrast, more education among survivors was linked to higher CQOL. CONCLUSION: These results (1) support using a mutuality framework for the study of long-term outcomes of caregivers, (2) suggest the importance of ongoing support for caregivers, and (3) help identify caregivers at risk for poorer adaptation. Poorer survivor functional health is a risk factor, but its adverse implications can be offset by higher caregiver and survivor sense of control, a psychological resource aiding caregiver adaptation. These findings can inform the development of support programs for long-term caregivers.

RESUMO

The goal of patient-centered outcomes research (PCOR) is to help patients and those who care for them make informed decisions about healthcare. However, the clinical research enterprise has not involved patients, caregivers, and other nonproviders routinely in the process of prioritizing, designing, and conducting research in hematopoietic cell transplantation (HCT). To address this need the National Marrow Donor Program/Be The Match engaged patients, caregivers, researchers, and other key stakeholders in a 2-year project with the goal of setting a PCOR agenda for the HCT community. Through a collaborative process we identified 6 major areas of interest: (1) patient, caregiver, and family education and support; (2) emotional, cognitive, and social health; (3) physical health and fatigue; (4) sexual health and relationships; (5) financial burden; and (6) models of survivorship care delivery. We then organized into multistakeholder working groups to identify gaps in knowledge and make priority recommendations for critical research to fill those gaps. Gaps varied by working group, but all noted that a historical lack of consistency in measures use and patient populations made it difficult to compare outcomes across studies and urged investigators to incorporate uniform measures and homogenous patient groups in future research. Some groups advised that additional pre-emptory work is needed before conducting prospective interventional trials, whereas others were ready to proceed with comparative clinical effectiveness research studies. This report presents the results of this major initiative and makes recommendations by working group on priority questions for PCOR in HCT.

RESUMO

OBJECTIVE: Little is known about how long-term cancer survivors adapt in the realm of work and finances, and whether there are differences in these adaptations based on overall health status. We hypothesize that survivors with better health-related quality of life (HQL) have better work and financial outcomes. STUDY DESIGN: Cross-sectional study with 200 adult recipients of autologous hematopoietic cell transplantation (HCT) 3-26 years after transplant using self-administered questionnaires and medical records extraction. MAIN OUTCOME MEASURES: Questionnaires assessed work status, financial satisfaction, and perceived improvements in financial status since transplant. RESULTS: Nearly half the survivors were employed (37.2% full-time, 8.7% part-time); 37.2% had retired. Higher scores on the functional HQL were linked to a lower relative risk of having retired (RRR 0.85, CI 0.75-0.98) and of being neither in the workforce nor retired (RRR 0.84, CI 0.72-0.99) compared with working full-time. Higher functional HQL also related to higher financial satisfaction (b 0.06, CI 0.01-0.10) and increased odds of perceived improvements in one's financial situation since transplant (OR 1.15, CI 1.04-1.17). Patients receiving HCT at age ≥60 were more likely than counterparts receiving HCT at age 18-39 to work part-time (RRR 18.24, 95% CI 1.19-280.24) and to have retired (Model 1 RRR 579.14, 95% CI 49.53-6771.54) than to be working full-time. CONCLUSIONS: Survivors with poorer HQL may be at risk for overall poorer work and financial adaptation. Interventions targeting this group and specifically focusing on re-integration into the world of paid work should be considered.

RESUMO

SETTING: National Institute of Diseases of the Chest and Hospital, Dhaka; Bangladesh Institute of Research and Rehabilitation in Diabetes, Endocrine and Metabolic Disorders, Dhaka; and Chittagong Chest Disease Hospital, Chittagong, Bangladesh. OBJECTIVE: To present operational data and discuss the challenges of implementing FAST (Find cases Actively, Separate safely and Treat effectively) as a tuberculosis (TB) transmission control strategy. DESIGN: FAST was implemented sequentially at three hospitals. RESULTS: Using Xpert® MTB/RIF, 733/6028 (12.2%, 95%CI 11.4-13.0) patients were diagnosed with unsuspected TB. Patients with a history of TB who were admitted with other lung diseases had more than twice the odds of being diagnosed with unsuspected TB as those with no history of TB (OR 2.6, 95%CI 2.2-3.0, P < 0.001). Unsuspected multidrug-resistant TB (MDR-TB) was diagnosed in 89/1415 patients (6.3%, 95%CI 5.1-7.7). Patients with unsuspected TB had nearly five times the odds of being diagnosed with MDR-TB than those admitted with a known TB diagnosis (OR 4.9, 95%CI 3.1-7.6, P < 0.001). Implementation challenges include staff shortages, diagnostic failure, supply-chain issues and reliance on external funding. CONCLUSION: FAST implementation revealed a high frequency of unsuspected TB in hospitalized patients in Bangladesh. Patients with a previous history of TB have an increased risk of being diagnosed with unsuspected TB. Ensuring financial resources, stakeholder engagement and laboratory capacity are important for sustainability and scalability.

RESUMO

In 2015, the National Institutes of Health convened six working groups to address the research needs and best practices for late effects of hematopoietic stem cell transplantation survivors. The Patient-Centered Outcomes Working Group, charged with summarizing the HRQOL evidence base, used a scoping review approach to efficiently survey the large body of literature in adult and pediatric HCT survivors over 1 year after transplantation. The goals of this paper are to (1) summarize the current literature describing patient-centered outcomes in survivors, including the various dimensions of health-related quality of life affected by HCT, and describe interventions tested to improve these outcomes; (2) highlight areas with sufficient evidence allowing for integration into standard practice; (3) address methodological issues that restrict progress in this field; (4) identify major gaps to guide future research; and (5) specify priority research recommendations. Patient-centered outcomes were summarized within physical, psychological, social, and environmental domains, as well as for adherence to treatment, and health behaviors. Interventions to improve outcomes were evaluated for evidence of efficacy, although few interventions have been tested in long-term HCT survivors. Methodologic issues defined included lack of consistency in the selection of patient-centered outcome measures, along with the absence of a standard for timing, frequency, and mode of administration. Recommendations for HCT survivorship care included integration of annual screening of patient-centered outcomes, use of evidence-based practice guidelines, and provision of treatment summaries and survivorship care plans after HCT. Three priority research recommendations included the following: (1) design and test risk-targeted interventions with dose-intensity modulation matching the needs of HCT survivors with priority domains, including sexual dysfunction, fatigue, sleep disruption, nonadherence to medications and recommended health care, health behaviors including physical inactivity and healthy eating, and psychological dysfunction, with particular consideration of novel technologies to reach HCT survivors distant from their transplantation centers; (2) design a consensus-based methodologic framework for outcomes evaluation; and (3) evaluate and compare existing practices for integrating patient-centered outcome screening and interventions across HCT survivorship programs.

RESUMO

Using semi-structured interviews with 50 hematopoietic stem cell transplantation (HSCT) recipients who were 2 to 22 years post-transplant, this study investigates cancer survivors' interpretations of their economic and work-related experiences during and after treatment. Survivors described a variety of challenges in these areas, including job insecurity, discrimination, career derailment, the lack of career direction, delayed goals, financial losses, insurance difficulties, constraints on job mobility, and physical/mental limitations. Survivors described the ways these challenges were offset by external factors that helped them to navigate these difficulties and buffered the negative financial and career-related impacts. Good health insurance, favorable job characteristics, job accommodations, and financial buffers were prominent offsetting factors. Most survivors, however, were also forced to rely on individual behavioral and interpretative strategies to cope with challenges. Behavioral strategies included purposeful job moves, retraining, striving harder, and retiring. Some strategies were potentially problematic, such as acquiring large debt. Interpretive strategies included reprioritizing and value shifts, downplaying the magnitude of cancer impact on one's life, denying the causal role of cancer in negative events, making favorable social comparisons, and benefit finding. Post-treatment counseling and support services may assist survivors in identifying available resources and useful strategies to improve long-term adaptation in the career and financial realms.

RESUMO

PURPOSE/OBJECTIVES: To describe sexuality, menopausal symptoms, and quality of life (QOL) in premenopausal women in the first year following hematopoietic cell transplantation (HCT)
. DESIGN: One-year prospective longitudinal study. SETTING: Stanford University Medical Center in California.
. SAMPLE: 63 premenopausal female recipients of HCT with a mean age of 34.5 years. METHODS: Three instruments were used. MAIN RESEARCH VARIABLES: Sexuality, menopausal symptoms, and QOL
. FINDINGS: At one year post-HCT, women reported absent to low desire and arousal, adequate lubrication less than half of the time, absent or rare orgasm, pain during vaginal penetration more than half the time, and dissatisfaction with overall sex life. Women also reported moderate to severe vasomotor symptoms, including hot flashes, night sweats, and sweating. Twenty-one women were avoiding sexual activity, and 25 women were not sexually active. Mean QOL scores significantly increased (p = 0.028) in the first year, signifying an improvement in QOL. Variables predictive of improved QOL at one year post-HCT include decreased psychosocial and physical symptoms, sexual satisfaction, and pre-HCT QOL score
. CONCLUSIONS: One year post-HCT, women reported sexual dysfunction, sexual dissatisfaction, and menopausal symptoms, which negatively affect QOL. IMPLICATIONS FOR NURSING: Nurses and other healthcare providers working with recipients of HCT can provide anticipatory guidance on potential changes in sexuality and menopausal symptoms to facilitate adaptation by reducing discordance between expectations and new realities

RESUMO

Blood and marrow transplantation (BMT) is a potentially curative therapy for a number of malignant and nonmalignant diseases. Multiple variables, including age, comorbid conditions, disease, disease stage, prior therapies, degree of donor-recipient matching, type of transplantation, and dose intensity of the preparative regimen, affect both morbidity and mortality. Despite tremendous gains in supportive care, BMT remains a high-risk medical therapy. A critically ill BMT recipient may require transfer to an intensive care unit (ICU) and the specialized medical and nursing care that can be provided, such as mechanical ventilation and vasopressor support. Mortality for BMT recipients requiring care in an ICU is high. This paper will describe the experience of the Stanford Blood and Marrow Transplant Program in developing and implementing guidelines to maximize the benefit of intensive care for critically ill BMT recipients.

RESUMO

We demonstrate wide-field real-time and depth-resolved contrast enhanced holographic imaging (CEHI) using the all-optical phase coherent photorefractive effect in ZnSe quantum wells. Moving objects are imaged at large depth-of-field by the local enhancement of a static reference hologram. The high refresh rate of the holographic films enables direct-to-video monitoring of floating glass beads and of living Paramecium and Euglena cells moving in water. Depth resolution is achieved by tilting the incident laser beam with respect to the normal of the cuvette. This creates double images of the objects, which are analyzed geometrically and with Fresnel diffraction theory. A two-color CEHI set-up further enables the visualization of a concealed 95 µm thick wire behind a thin layer of chicken skin.

RESUMO

OBJECTIVES: To provide support for the early integration of palliative care into the care of hematopoietic cell transplant (HCT) recipients and families with the goal of improving care. DATA SOURCES: Journal articles and on-line databases. CONCLUSION: Early integration of palliative care for HCT recipients at high risk for complex symptom clusters, non-relapse mortality, or relapse offers an opportunity to clarify goals of care, advanced care planning, and improving the quality of care for both recipients and families. IMPLICATIONS FOR NURSING PRACTICE: The palliative care service can support the HCT nurse in providing complex care to HCT recipients who are faced with significant side effects, toxicities, and complications of transplant.

RESUMO

Gamma-ray burst (GRB) 130427A is one of the most energetic GRBs ever observed. The initial pulse up to 2.5 seconds is possibly the brightest well-isolated pulse observed to date. A fine time resolution spectral analysis shows power-law decays of the peak energy from the onset of the pulse, consistent with models of internal synchrotron shock pulses. However, a strongly correlated power-law behavior is observed between the luminosity and the spectral peak energy that is inconsistent with curvature effects arising in the relativistic outflow. It is difficult for any of the existing models to account for all of the observed spectral and temporal behaviors simultaneously.

RESUMO

Autologous hematopoietic stem cell transplantation (HSCT) is a potentially curative therapeutic approach for various malignant hematologic and lymphoid diseases. Hematopoietic stem cells (HSCs) may be collected from the blood or the bone marrow. HSCs are capable of self-renewal and give rise to progenitor cells, multipotent cells that differentiate and proliferate into the mature cells of the blood and immune system. HSCs and progenitor cells are released from the bone marrow into the peripheral blood through a process called mobilization. HSCs then are collected from the blood in a process called apheresis and cryopreserved for administration following the high-dose preparative regimen. This article reviews stem cell biology, current mobilization strategies, use of novel mobilization agents, and nursing care of patients during the mobilization phase of autologous HSCT. Understanding the biology and process of HSC mobilization is critical for transplantation nurses to deliver and coordinate care during this complex phase of autologous HSCT.

RESUMO

PURPOSE/OBJECTIVES: To examine practice variation in hematopoietic stem cell transplantation (HSCT) nursing and to identify the gap between recommended standards of practice and actual practice across settings. Additional practices relevant to HSCT nursing also were explored. RESEARCH APPROACH: Cross-sectional, descriptive survey. SETTING: National and international cancer centers. PARTICIPANTS: A convenience sample was obtained from the 2006 Oncology Nursing Society Blood and Marrow Stem Cell Transplant Special Interest Group membership list (N = 205). Most participants were women (94%) with a median age of 45 years. The primary role was bedside nurse (46%), with an adult-only population (78%) in an academic (84%), inpatient (68%-88%) center. 39 (94%) U.S. states and 7 (6%) non-U.S. countries were represented. METHODOLOGIC APPROACH: Survey development was guided by Dillman Mail and Internet survey design. Electronic questionnaires were conducted with Zoomerang Market Tools. MAIN RESEARCH VARIABLES: Infection control practices across bone marrow transplantation settings. FINDINGS: Descriptive statistics revealed minimal practice variation regarding infection control across transplantation types or conditioning regimens. Practices regarding implementation of restrictions on patients' hygiene, diet, and social interactions varied by phase of transplantation, with the greatest variations occurring during the post-transplantation phase. Sixty-two percent of respondents reported using published guidelines; 72% reported using organization-specific policies. CONCLUSIONS: Although published standards are under consideration, practice variation exists across transplantation centers. Whether the variation is caused by a lack of compliance with published guidelines or by the poor delineation of details for providers to translate the guidelines into practice is not known. INTERPRETATION: Identifying gaps in the literature and inconsistencies in HSCT practices is an important first step in designing evidence-based projects that can be used to standardize practice and link best practices to improved patient outcomes.

RESUMO

OBJECTIVES: To provide an overview of the broad, multidimensional construct of sexuality addressing physiologic, psychological, and social dimensions. DATA SOURCES: Research articles, abstracts, standards of care, international reports. CONCLUSION: Multiple insults to the physiologic, psychological, and social dimensions of sexuality can occur following the diagnosis and treatment of cancer. The incidence of altered sexuality in cancer survivors is high, long lasting, and can diminish the quality of life of both the cancer survivor and the sexual partner. Additional research is needed to address these alterations. IMPLICATIONS FOR NURSING PRACTICE: Nurses and other health care professions can begin to help cancer survivors adapt to changes in sexuality related to cancer and cancer treatment by initiating a discussion of sexuality at the time of diagnosis and throughout the trajectory of disease.
