RESUMO

BACKGROUND: Before the emergence of the B.1.617.2 (delta) variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), vaccination reduced transmission of SARS-CoV-2 from vaccinated persons who became infected, potentially by reducing viral loads. Although vaccination still lowers the risk of infection, similar viral loads in vaccinated and unvaccinated persons who are infected with the delta variant call into question the degree to which vaccination prevents transmission. METHODS: We used contact-testing data from England to perform a retrospective observational cohort study involving adult contacts of SARS-CoV-2-infected adult index patients. We used multivariable Poisson regression to investigate associations between transmission and the vaccination status of index patients and contacts and to determine how these associations varied with the B.1.1.7 (alpha) and delta variants and time since the second vaccination. RESULTS: Among 146,243 tested contacts of 108,498 index patients, 54,667 (37%) had positive SARS-CoV-2 polymerase-chain-reaction (PCR) tests. In index patients who became infected with the alpha variant, two vaccinations with either BNT162b2 or ChAdOx1 nCoV-19 (also known as AZD1222), as compared with no vaccination, were independently associated with reduced PCR positivity in contacts (adjusted rate ratio with BNT162b2, 0.32; 95% confidence interval [CI], 0.21 to 0.48; and with ChAdOx1 nCoV-19, 0.48; 95% CI, 0.30 to 0.78). Vaccine-associated reductions in transmission of the delta variant were smaller than those with the alpha variant, and reductions in transmission of the delta variant after two BNT162b2 vaccinations were greater (adjusted rate ratio for the comparison with no vaccination, 0.50; 95% CI, 0.39 to 0.65) than after two ChAdOx1 nCoV-19 vaccinations (adjusted rate ratio, 0.76; 95% CI, 0.70 to 0.82). Variation in cycle-threshold (Ct) values (indicative of viral load) in index patients explained 7 to 23% of vaccine-associated reductions in transmission of the two variants. The reductions in transmission of the delta variant declined over time after the second vaccination, reaching levels that were similar to those in unvaccinated persons by 12 weeks in index patients who had received ChAdOx1 nCoV-19 and attenuating substantially in those who had received BNT162b2. Protection in contacts also declined in the 3-month period after the second vaccination. CONCLUSIONS: Vaccination was associated with a smaller reduction in transmission of the delta variant than of the alpha variant, and the effects of vaccination decreased over time. PCR Ct values at diagnosis of the index patient only partially explained decreased transmission. (Funded by the U.K. Government Department of Health and Social Care and others.).

RESUMO

This panel paper is the third installment in a six-part Nursing Outlook special edition based on the 2022 Emory Business Case for Nursing Summit. The 2022 summit was led by Emory School of Nursing in partnership with Emory School of Business. It convened national nursing, health care, and business leaders to explore possible solutions to nursing workforce crises, including the nursing shortage. Each of the summit's four panels authored a paper in this special edition on their respective topic(s). This panel paper focuses on strategies to optimally distribute nursing talent in rural and underserved areas. It discusses the role of nursing talent distribution in ensuring equity in access to care for U.S. populations. Topics covered include the need for expanded and standardized advanced practice registered nurse (APRN) scope of practice, an expanded nurse licensure compact, reimbursement reforms, and competitive nursing salaries.

RESUMO

BACKGROUND Transitional care and medical respite programs provide assistance to people experiencing homelessness as they move from acute care into community settings. These programs can address issues that may fall outside the reach of traditional medical care yet have a profound impact on the health of vulnerable populations. This article focuses on the cost-effectiveness of the Durham Homeless Care Transitions (DHCT) program.METHOD This intervention study of the DHCT program uses a comparison group of people experiencing homelessness who were referred but did not participate. Encounter-level data, aggregated by quarterly segments of charges and reimbursements, were abstracted for all persons referred. Descriptive statistics were computed and models of charges and reimbursements were created using ordinary least squares (OLS) regression to compare utilization for 12 months pre- and post-referral.RESULTS Patients referred to the DHCT program (N = 485) were primarily non-Hispanic Black (62.5%), male (68.4%), uninsured (35.5%), and had an average of 5.3 chronic conditions and an average age of 50.0 years (SD = 11.3). There was variability among charges and reimbursement based on health care visit type but a negative association between treatment and charges, indicating that being part of the DHCT program led to lower charges post-referral.LIMITATIONS The study is limited by lack of access to line-item details of charges, reimbursement, and payer mix.CONCLUSION There is evidence of benefit to patients from transitional care and medical respite programs that does not substantially increase the overall societal cost of care; however, health systems commonly require evidence of cost savings and benefit as a return on investment.

RESUMO

BACKGROUND: In a randomized control trial, Palliative Care in Heart Failure (PAL-HF) improved heart failure-related quality of life, though cost-effectiveness remains unknown. The aim of this study was to evaluate the cost-effectiveness of the PAL-HF trial, which provided outpatient palliative care to patients with advanced heart failure. METHODS AND RESULTS: Outcomes for usual care and PAL-HF strategies were compared using a Markov cohort model over 36 months from a payer perspective. The model parameters were informed by PAL-HF trial data and supplemented with meta-analyses and Medicare administrative data. Outcomes included hospitalization, place of death, Medicare expenditures, quality-adjusted life years (QALYs), and incremental cost-effectiveness ratios. Simulated mortality rates were the same for PAL-HF and usual care cohorts, at 89.7% at 36 months. In the base case analysis, the PAL-HF intervention resulted in an incremental gain of 0.03 QALYs and an incremental cost of $964 per patient for an incremental cost-effectiveness ratio of $29,041 per QALY. In 1-way sensitivity analyses, an intervention cost of up to $140 per month is cost effective at $50,000 per QALY. Of 1000 simulations, the PC intervention had a 66.1% probability of being cost effective at a $50,000 willingness-to-pay threshold assuming no decrease in hospitalization. In a scenario analysis, PAL-HF decreased payer spending through reductions in noncardiovascular hospitalizations. CONCLUSIONS: These results from this single-center trial are encouraging that palliative care for advanced heart failure is an economically attractive intervention. Confirmation of these findings in larger multicenter trials will be an important part of developing the evidence to support more widespread implementation of the PAL-HF palliative care intervention.

RESUMO

BACKGROUND: The National Cancer Institute Informatics Technology for Cancer Research (ITCR) program provides a series of funding mechanisms to create an ecosystem of open-source software (OSS) that serves the needs of cancer research. As the ITCR ecosystem substantially grows, it faces the challenge of the long-term sustainability of the software being developed by ITCR grantees. To address this challenge, the ITCR sustainability and industry partnership working group (SIP-WG) was convened in 2019. OBJECTIVE: The charter of the SIP-WG is to investigate options to enhance the long-term sustainability of the OSS being developed by ITCR, in part by developing a collection of business model archetypes that can serve as sustainability plans for ITCR OSS development initiatives. The working group assembled models from the ITCR program, from other studies, and from the engagement of its extensive network of relationships with other organizations (eg, Chan Zuckerberg Initiative, Open Source Initiative, and Software Sustainability Institute) in support of this objective. METHODS: This paper reviews the existing sustainability models and describes 10 OSS use cases disseminated by the SIP-WG and others, including 3D Slicer, Bioconductor, Cytoscape, Globus, i2b2 (Informatics for Integrating Biology and the Bedside) and tranSMART, Insight Toolkit, Linux, Observational Health Data Sciences and Informatics tools, R, and REDCap (Research Electronic Data Capture), in 10 sustainability aspects: governance, documentation, code quality, support, ecosystem collaboration, security, legal, finance, marketing, and dependency hygiene. RESULTS: Information available to the public reveals that all 10 OSS have effective governance, comprehensive documentation, high code quality, reliable dependency hygiene, strong user and developer support, and active marketing. These OSS include a variety of licensing models (eg, general public license version 2, general public license version 3, Berkeley Software Distribution, and Apache 3) and financial models (eg, federal research funding, industry and membership support, and commercial support). However, detailed information on ecosystem collaboration and security is not publicly provided by most OSS. CONCLUSIONS: We recommend 6 essential attributes for research software: alignment with unmet scientific needs, a dedicated development team, a vibrant user community, a feasible licensing model, a sustainable financial model, and effective product management. We also stress important actions to be considered in future ITCR activities that involve the discussion of the sustainability and licensing models for ITCR OSS, the establishment of a central library, the allocation of consulting resources to code quality control, ecosystem collaboration, security, and dependency hygiene.

RESUMO

North Carolina's refusal to expand its Medicaid program has left many thousands of North Carolinians without health insurance and has imposed unnecessary costs on all of the state's residents through higher premiums in the state's health insurance marketplace. Expanding Medicaid is the most efficient way to extend coverage to the state's uninsured population, and expansion would bring a substantial amount of new federal money into the state. This money can serve as a catalyst for ambitious reforms to the Medicaid program that can lower costs, improve quality of care, and increase value for patients and taxpayers alike.

RESUMO

BACKGROUND: Cancer patients may experience financial distress as a side effect of their care. Little is known about which patients are at greatest risk for altering their care or lifestyle due to treatment-related financial distress. METHODS: We conducted a cross-sectional survey study to determine which patients are at greatest risk for altering their care or lifestyle due to treatment-related financial distress. Eligible patients were adults receiving cancer treatment enrolled between June 2010 and May 2011. We grouped coping strategies as lifestyle altering or care altering. We assessed coping strategies and relationships between covariates using descriptive statistics and analysis of variance. RESULTS: Among 174 participants, 89% used at least one lifestyle-altering coping strategy, while 39% used a care-altering strategy. Care-altering coping strategies adopted by patients included the following: not filling a prescription (28%) and taking less medication than prescribed (23%). Lifestyle-altering strategies included the following: spending less on leisure activities (77%), spending less on basics like food and clothing (57%), borrowing money (54%), and spending savings (50%). Younger patients were more likely than older patients to use coping strategies (p < 0.001). Lower-income patients adopted care-altering strategies more than higher-income patients (p = 0.03). Participants with more education and shorter duration of chemotherapy used lifestyle-altering strategies more than their counterparts (both p < 0.05). CONCLUSIONS: As a means of coping with treatment-related financial distress, patients were more likely to use lifestyle-altering approaches, but more than one-third adopted potentially harmful care-altering strategies. Younger age, lower income, higher education, and shorter duration of chemotherapy were characteristics associated with greater use of coping strategies. Copyright © 2015 John Wiley & Sons, Ltd.

RESUMO

BACKGROUND: Health care-related costs and satisfaction are compelling targets for quality improvement in cancer care delivery; however, little is known about how financial burden affects patient satisfaction. METHODS: This was an observational, cross-sectional, survey-based study assessing patient-reported financial burden (FB). Eligible patients were ≥ 21 years with solid tumor malignancy and were receiving chemotherapy or hormonal therapy for ≥ 1 month. The Patient Satisfaction Questionnaire Short-Form assessed patient satisfaction with health care. Subjective FB related to cancer treatment was measured on a 5-point Likert scale. RESULTS: Of 174 participants (32% response rate), 47% reported significant/catastrophic FB. Participants reported highest satisfaction with interpersonal manner and lowest satisfaction with financial aspects of care. In adjusted analysis, high FB was negatively associated with general satisfaction (coefficient: -.29), satisfaction with technical quality (coefficient: -.26), and satisfaction with financial aspects of care (coefficient: -.62). Older age was associated with higher scores in all satisfaction subscales except patient-physician communication and financial aspects. Annual household income of <$20,000 was associated with lower satisfaction scores in all subscales except time spent with doctor. High FB was not associated with patient satisfaction scores for accessibility and convenience, communication, interpersonal manner, or time spent with doctor. CONCLUSION: FB is a potentially modifiable correlate of poor satisfaction with cancer care including general satisfaction and satisfaction with the technical quality of care. Addressing cancer-associated FB may lead to improved satisfaction, which in turn can influence adherence, outcomes, and quality of life.

RESUMO

Nearly half of breast carcinoma metastases will become clinically evident five or more years after primary tumor ablation. This implies that metastatic cancer cells survived over an extended timeframe without emerging as detectable nodules. The liver is a common metastatic destination, whose parenchymal hepatocytes have been shown to impart a less invasive, dormant phenotype on metastatic cancer cells. We investigated whether hepatic nonparenchymal cells (NPCs) contributed to metastatic breast cancer cell outgrowth and a mesenchymal phenotypic shift indicative of emergence. Co-culture experiments of primary human hepatocytes, NPCs or endothelial cell lines (TMNK-1 or HMEC-1) and breast cancer cell lines (MCF-7 or MDA-MB-231) were conducted. Exposure of carcinoma cells to NPC-conditioned medium isolated soluble factors contributing to outgrowth. To elucidate outgrowth mechanism, epidermal growth factor receptor (EGFR) inhibition co-culture experiments were performed. Flow cytometry analyses and immunofluorescence staining were conducted to quantify breast cancer cell outgrowth and phenotype, respectively. Outgrowth of the MDA-MB-231 cells within primary NPC co-cultures was substantially greater than in hepatocyte-only or hepatocyte+NPC co-cultures. MCF-7 cells co-cultured with human NPCs as well as with the endothelial NPC subtypes grew out significantly more than controls. MCF-7 cells underwent a mesenchymal shift as indicated by spindle morphology, membrane clearance of E-cadherin, and p38 nuclear translocation when in HMEC-1 co-culture. HMEC-1-conditioned medium induced similar results suggesting that secretory factors are responsible for this transition while blocking EGFR blunted the MCF-7 outgrowth. We conclude that NPCs in the metastatic hepatic niche secrete factors that can induce a partial mesenchymal shift in epithelial breast cancer cells thus initiating outgrowth, and that this is in part mediated by EGFR activation. These data suggest that changes in the parenchymal cell and NPC ratios (or activation status) in the liver metastatic microenvironment may contribute to emergence from metastatic dormancy.

RESUMO

BACKGROUND: The progressive nature of heart failure (HF) coupled with high mortality and poor quality of life mandates greater attention to palliative care as a routine component of advanced HF management. Limited evidence exists from randomized, controlled trials supporting the use of interdisciplinary palliative care in HF. METHODS: PAL-HF is a prospective, controlled, unblinded, single-center study of an interdisciplinary palliative care intervention in 200 patients with advanced HF estimated to have a high likelihood of mortality or rehospitalization in the ensuing 6 months. The 6-month PAL-HF intervention focuses on physical and psychosocial symptom relief, attention to spiritual concerns, and advanced care planning. The primary end point is health-related quality of life measured by the Kansas City Cardiomyopathy Questionnaire and the Functional Assessment of Chronic Illness Therapy with Palliative Care Subscale score at 6 months. Secondary end points include changes in anxiety/depression, spiritual well-being, caregiver satisfaction, cost and resource utilization, and a composite of death, HF hospitalization, and quality of life. CONCLUSIONS: PAL-HF is a randomized, controlled clinical trial that will help evaluate the efficacy and cost effectiveness of palliative care in advanced HF using a patient-centered outcome as well as clinical and economic end points.

RESUMO

BACKGROUND: Concerns about unsustainable costs in the US Medicare program loom as the number of retirees increase and experiences serious and costly illnesses like cancer. Engagement of stakeholders, particularly cancer patients and their families, in prioritizing insured services offers a valuable strategy for informing Medicare coverage policy. We designed and evaluated a decision exercise that allowed cancer patients and family members to choose Medicare benefits for advanced cancer patients. METHODS: The decision tool, Choosing Health plans All Together (CHAT) was modified to select services for advanced cancer patients. Patients with a cancer history (N = 246) and their family members (N = 194) from North Carolina participated in 70 CHAT sessions. Variables including participants' socio-demographic characteristics, health status, assessments of the exercise and results of group benefit selections were collected. Routine descriptive statistics summarized participant characteristics and Fisher's exact test compared group differences. Qualitative analysis of group discussions were used to ascertain reasons for or against selecting benefits. RESULTS: Patients and family members (N = 440) participated in 70 CHAT exercises. Many groups opted for such services as palliative care, nursing facilities, and services not currently covered by the Medicare program. In choosing among four levels of cancer treatment coverage, no groups chose basic coverage, 27 groups (39%) selected intermediate coverage, 39 groups (56%) selected high coverage, and 4 groups (6%) chose the most comprehensive cancer coverage. Reasons for or against benefit selection included fairness, necessity, need for prioritizing, personal experience, attention to family needs, holistic health outlook, preference for comfort, freedom of choice, and beliefs about the proper role of government. Participants found the exercise very easy (59%) or fairly easy (39%) to understand and very informative (66%) or fairly informative (31%). The majority agreed that the CHAT exercise led to fair decisions about priorities for coverage by which they could abide. CONCLUSIONS: It is possible to involve cancer patients and families in explicit discussions of their priorities for affordable advanced cancer care through the use of decision tools designed for this purpose. A key question is whether such a conversation is possible on a broader, national level.

RESUMO

PURPOSE: Cancer patients carry rising burdens of health care-related out-of-pocket expenses, and a growing number of patients are considered "underinsured." Our objective was to describe experiences of insured cancer patients requesting copayment assistance and to describe the impact of health care expenses on well-being and treatment. METHODS: We conducted baseline and follow-up surveys regarding the impact of health care costs on well-being and treatment among cancer patients who contacted a national copayment assistance foundation along with a comparison sample of patients treated at an academic medical center. RESULTS: Among 254 participants, 75% applied for drug copayment assistance. Forty-two percent of participants reported a significant or catastrophic subjective financial burden; 68% cut back on leisure activities, 46% reduced spending on food and clothing, and 46% used savings to defray out-of-pocket expenses. To save money, 20% took less than the prescribed amount of medication, 19% partially filled prescriptions, and 24% avoided filling prescriptions altogether. Copayment assistance applicants were more likely than nonapplicants to employ at least one of these strategies to defray costs (98% vs. 78%). In an adjusted analysis, younger age, larger household size, applying for copayment assistance, and communicating with physicians about costs were associated with greater subjective financial burden. CONCLUSION: Insured patients undergoing cancer treatment and seeking copayment assistance experience considerable subjective financial burden, and they may alter their care to defray out-of-pocket expenses. Health insurance does not eliminate financial distress or health disparities among cancer patients. Future research should investigate coverage thresholds that minimize adverse financial outcomes and identify cancer patients at greatest risk for financial toxicity.

RESUMO

Mycorrhizal association is a common characteristic in a majority of land plants, and the survival and distribution of a species can depend on the distribution of suitable fungi in its habitat. Orchidaceae is one of the most species-rich angiosperm families, and all orchids are fully dependent on fungi for their seed germination and some also for subsequent growth and survival. Given this obligate dependence, at least in the early growth stages, elucidating the patterns of orchid-mycorrhizal relationships is critical to orchid biology, ecology and conservation. To assess whether rarity of an orchid is determined by its specificity towards its fungal hosts, we studied the spatial and temporal variability in the host fungi associated with one of the rarest North American terrestrial orchids, Piperia yadonii. The fungal internal transcribed spacer region was amplified and sequenced by sampling roots from eight populations of P. yadonii distributed across two habitats, Pinus radiata forest and maritime chaparral, in California. Across populations and sampling years, 26 operational taxonomic units representing three fungal families, the Ceratobasidiaceae, Sebacinaceae and Tulasnellaceae, were identified. Fungi belonging to the Sebacinaceae were documented in orchid roots only at P. radiata forest sites, while those from the Ceratobasidiaceae and Tulasnellaceae occurred in both habitats. Our results indicate that orchid rarity can be unrelated to the breadth of mycorrhizal associations. Our data also show that the dominance of various fungal families in mycorrhizal plants can be influenced by habitat preferences of mycorrhizal partners.

RESUMO

Importance: Beneficiaries dual eligible for Medicare and Medicaid account for a disproportionate share of expenditures due to their complex care needs. Lack of coordination between payment programs creates misaligned incentives, resulting in higher costs, fragmented care, and poor health outcomes. Objective: To inform the design of integrated programs by describing the health care use and spending for need-based subgroups in North Carolina's full benefit, dual-eligible population. Design, Setting, and Participants: This cross-sectional study using Medicare and North Carolina Medicaid 100% claims data (2014-2017) linked at the individual level included Medicare beneficiaries with full North Carolina Medicaid benefits. Data were analyzed between 2021 and 2022. Exposure: Need-based subgroups: community well, home- and community-based services (HCBS) users, nursing home (NH) residents, and intensive behavioral health (BH) users. Measures: Medicare and Medicaid utilization and spending per person-year (PPY). Results: The cohort (n = 333 240) comprised subgroups of community well (64.1%, n = 213 667), HCBS users (15.0%, n = 50 095), BH users (15.2%, n = 50 509), and NH residents (7.5%, n = 24 927). Overall, 61.1% reported female sex. The most common racial identities included Asian (1.8%), Black (36.1%), and White (58.7%). Combined spending for Medicare and Medicaid was $26 874 PPY, and the funding of care was split evenly between Medicare and Medicaid. Among need-based subgroups, combined spending was lowest among community well at $19 734 PPY with the lowest portion (38.5%) of spending contributed by Medicaid ($7605). Among NH residents, overall spending ($68 359) was highest, and the highest portion of spending contributed by Medicaid (70.1%). Key components of spending among HCBS users' combined total of $40 069 PPY were clinician services on carrier claims ($14 523) and outpatient facility services ($9012). Conclusions and relevance: Federal and state policy makers and administrators are developing strategies to integrate Medicare- and Medicaid-funded health care services to provide better care to the people enrolled in both programs. Substantial use of both Medicare- and Medicaid-funded services was found across all need-based subgroups, and the services contributing a high proportion of the total spending differed across subgroups. The diversity of health care use suggests a tailored approach to integration strategies with comprehensive set benefits that comprises Medicare and Medicaid services, including long-term services and supports, BH, palliative care, and social services.

RESUMO

Introduction: The COVID-19 pandemic focused attention on healthcare disparities and inequities faced by individuals within marginalized and structurally disadvantaged groups in the United States. These individuals bore the heaviest burden across this pandemic as they faced increased risk of infection and difficulty in accessing testing and medical care. Individuals experiencing housing insecurity are a particularly vulnerable population given the additional barriers they face. In this scoping review, we identify some of the barriers this high-risk group experienced during the early days of the pandemic and assess novel solutions to overcome these barriers. Methods: A scoping review was performed following PRISMA-Sc guidelines looking for studies focusing on COVID-19 testing among individuals experiencing housing insecurity. Barriers as well as solutions to barriers were identified as applicable and summarized using qualitative methods, highlighting particular ways that proved effective in facilitating access to testing access and delivery. Results: Ultimately, 42 studies were included in the scoping review, with 143 barriers grouped into four categories: lack of cultural understanding, systemic racism, and stigma; medical care cost, insurance, and logistics; immigration policies, language, and fear of deportation; and other. Out of these 42 studies, 30 of these studies also suggested solutions to address them. Conclusion: A paucity of studies have analyzed COVID-19 testing barriers among those experiencing housing insecurity, and this is even more pronounced in terms of solutions to address those barriers. Expanding resources and supporting investigators within this space is necessary to ensure equitable healthcare delivery.

RESUMO

Optimal management of breakthrough cancer pain (BTCP) requires analgesics with a rapid onset of action, consistent efficacy, improved patient acceptability and tolerability and ease of use. Fentanyl pectin nasal spray (FPNS) incorporates a proprietary pectin-based gelling agent to enhance absorption and produce a faster onset of action and consistent plasma concentration. FPNS is indicated for the treatment of breakthrough pain in cancer patients who are tolerant to opioid therapy for their underlying persistent cancer pain. FPNS has been evaluated in clinical studies in patients with BTCP and shown to be effective, safe and well tolerated. In addition, FPNS has demonstrated high levels of patient satisfaction, convenience and ease of use. FPNS therefore represents an important addition to the treatment options for BTCP.

RESUMO

PURPOSE: Previous studies show that fentanyl pectin nasal spray (FPNS) rapidly provides clinically meaningful pain relief in the treatment of breakthrough cancer pain (BTCP). This study assessed the long-term tolerability, acceptability and consistency of effect of FPNS in patients with BTCP. METHODS: Patients (new and rolled over from earlier controlled studies) with cancer experiencing one to four episodes per day of BTCP whilst taking ≥ 60 mg/day of morphine (or equivalent) given orally for cancer pain entered an open-label 16-week safety study. Safety and tolerability were assessed by adverse events (AEs), adverse drug reactions (ADRs), withdrawal due to AEs and by nasal assessments. Acceptability assessments included ratings of overall satisfaction with each treated episode and ease of use and convenience of FPNS. Additional rescue medication and dose stability were used to evaluate the consistency of effect. RESULTS: Four hundred three patients were included in the safety and intent-to-treat analysis (42,227 episodes), 356 entered the treatment phase and 110 completed 16 weeks. Overall, 24.6% of 403 patients reported treatment-related treatment-emergent AEs that were generally mild/moderate and typical of opioids; 20 patients discontinued treatment due to an AE (9 were ADRs). Nasal assessments revealed no clinically significant effects; 94% of FPNS-treated episodes required no additional rescue medication. More than 90% of patients did not have to increase their dose during the study. Patients reported overall satisfaction with FPNS for 90.1% of episodes. At week 12, 96.9% of patients were satisfied with the ease of use and 97.9% with the convenience of FPNS. CONCLUSIONS: FPNS was generally well tolerated and well accepted for the treatment of BTCP, and doses remained stable over the 4-month study period.

RESUMO

Research in low Earth orbit (LEO) has become more accessible. The 2020 Biomanufacturing in Space Symposium reviewed space-based regenerative medicine research and discussed leveraging LEO to advance biomanufacturing for regenerative medicine applications. The symposium identified areas where financial investments could stimulate advancements overcoming technical barriers. Opportunities in disease modeling, stem-cell-derived products, and biofabrication were highlighted. The symposium will initiate a roadmap to a sustainable market for regenerative medicine biomanufacturing in space. This perspective summarizes the 2020 Biomanufacturing in Space Symposium, highlights key biomanufacturing opportunities in LEO, and lays the framework for a roadmap to regenerative medicine biomanufacturing in space.
