Comparative single-cell transcriptional and proteomic atlas of clinical-grade injectable mesenchymal source tissues.

Bone marrow aspirate concentrate (BMAC) and adipose-derived stromal vascular fraction (ADSVF) are the most marketed stem cell therapies to treat a variety of conditions in the general population and elite athletes. Both tissues have been used interchangeably clinically even though their detailed composition, heterogeneity, and mechanisms of action have neither been rigorously inventoried nor compared. This lack of information has prevented investigations into ideal dosages and has facilitated anecdata and misinformation. Here, we analyzed single-cell transcriptomes, proteomes, and flow cytometry profiles from paired clinical-grade BMAC and ADSVF. This comparative transcriptional atlas challenges the prevalent notion that there is one therapeutic cell type present in both tissues. We also provide data of surface markers that may enable isolation and investigation of cell (sub)populations. Furthermore, the proteome atlas highlights intertissue and interpatient heterogeneity of injected proteins with potentially regenerative or immunomodulatory capacities.

Widespread Pressure Delivered by a Weighted Blanket Reduces Chronic Pain: A Randomized Controlled Trial.

Pleasant sensation is an underexplored avenue for modulation of chronic pain. Deeper pressure is perceived as pleasant and calming, and can improve sleep. Although pressure can reduce acute pain, its effect on chronic pain is poorly characterized. The current remote, double-blind, randomized controlled trial tested the hypothesis that wearing a heavy weighted blanket - providing widespread pressure to the body - relative to a light weighted blanket would reduce ratings of chronic pain, mediated by improvements in anxiety and sleep. Ninety-four adults with chronic pain were randomized to wear a 15-lb. (heavy) or 5-lb. (light) weighted blanket during a brief trial and overnight for one week. Measures of anxiety and chronic pain were collected pre- and post-intervention, and ratings of pain intensity, anxiety, and sleep were collected daily. After controlling for expectations and trait anxiety, the heavy weighted blanket produced significantly greater reductions in broad perceptions of chronic pain than the light weighted blanket (Cohen's f = .19, CI [-1.97, -.91]). This effect was stronger in individuals with high trait anxiety (P = .02). However, weighted blankets did not alter pain intensity ratings. Pain reductions were not mediated by anxiety or sleep. Given that the heavy weighted blanket was associated with greater modulation of affective versus sensory aspects of chronic pain, we propose that the observed reductions are due to interoceptive and social/affective effects of deeper pressure. Overall, we demonstrate that widespread pressure from a weighted blanket can reduce the severity of chronic pain, offering an accessible, home-based tool for chronic pain. The study purpose, targeted condition, study design, and primary and secondary outcomes were pre-registered in ClinicalTrials.gov (NCT04447885: "Weighted Blankets and Chronic Pain"). PERSPECTIVE: This randomized-controlled trial showed that a 15-lb weighted blanket produced significantly greater reductions in broad perceptions of chronic pain relative to a 5-lb weighted blanket, particularly in highly anxious individuals. These findings are relevant to patients and providers seeking home-based, nondrug therapies for chronic pain relief.

Pediatric palliative care consultation services in California hospitals.

BACKGROUND: The American Academy of Pediatrics recommends that palliative care be available to seriously ill hospitalized children, yet little is known about how these services are structured. OBJECTIVE: The study's aim is to report the prevalence of pediatric palliative care services (PCS) and compare the structure of pediatric PCS to adult PCS within California hospitals. METHODS: We surveyed 377 hospitals to assess the prevalence, structure, and characteristics of pediatric and adult PCS. Hospitals were categorized as children's hospitals with a pediatric-only PCS, mixed hospitals with pediatric and adult PCS, and hospitals with adult-only PCS. RESULTS: All 8 children's hospitals in the state reported having a pediatric PCS, and 36 pediatric PCSs were in mixed hospitals. Mixed hospitals saw fewer (p=0.0001) children per year (mean=5.6, standard deviation [SD]=3.6) than pediatric-only PCSs (mean=168, SD=73). Pediatric-only PCSs treated more patients for noncancer-related illness (82.5%) than pediatric PCSs in mixed hospitals (34.5%, p=0.03) or adult-only PCSs (52.4%, p=0.001). All PCSs were universally available (100%) during weekday business hours and half were available during weekend business hours. Pediatric-only PCSs had a mean total full-time equivalent (FTE) of 1.9, which was not significantly different (p=0.3) from the total FTE for pediatric PCSs in mixed hospitals (mean=1.1, SD=1.4) or for adult-only PCSs (mean=2.7, SD=2.0). However, in mixed hospitals the adult PCS had a significantly higher (p=0.005) total FTE (mean=2.4, SD=1.3) than the pediatric PCS (mean=1.1, SD=1.4). CONCLUSION: All children's hospital and a few mixed hospitals offer pediatric PCS. Better understanding of the palliative care needs of seriously ill children in mixed hospitals and assessment of the quality of care provided will help ensure that children seen in these hospitals receive necessary care.

Two steps forward, one step back: changes in palliative care consultation services in California hospitals from 2007 to 2011.

BACKGROUND: The number of palliative care consultation services is growing, yet little is known about how program characteristics change over time. OBJECTIVE: Compare changes in the characteristics of palliative care programs and palliative care consultation services in 2007 and 2011. DESIGN: We surveyed all hospitals in California in 2011 and compared palliative care program and palliative care consultation service characteristics with survey results from 2007. RESULTS: There were 41 new palliative care programs since 2007; 17 programs closed between 2007 and 2011. Hospital characteristics associated with the closure of a palliative care program included a hospital size of 1-149 beds versus 150 or more (p=0.03), for-profit status (p=0.001), and having no system affiliation (p=0.0001). The prevalence of palliative care consultation services was 33% in 2007 and 37% in 2011 (p=0.3). At both time periods nearly all palliative care consultation services (98%) were available onsite during weekday business hours and only half were available at other times (p=0.4). There was an increase (p=0.002) in nurse/physician full-time equivalent (FTE; 2007, mean=1.5; 95% confidence interval [CI]=1.3-1.7; 2011, mean=1.9; 95% CI=1.6-2.2) but fewer teams reported having social workers (58% versus 80%, p=0.002) and chaplains (58% versus 77%, p=0.0001) in 2011. Over half of the palliative care consultation services reported seeing less than 50% of patients who would benefit from a consultation (2007: 59%, 2011=50%, p=0.2), yet most also reported struggling to cope with patient volume (2007: 62%; 2011: 66%, p=0.5). CONCLUSIONS: Fewer than half of hospitals in California offer a palliative care program and many close over time. Making palliative care consultation services a condition of participation by insurers could make hospital palliative care consultation services universal. Mechanisms need to be established to improve staffing levels, maintain the interdisciplinary nature of palliative care consultation services, and accommodate demand for services.

Characteristics of palliative care consultation services in California hospitals.

BACKGROUND: Although hospital palliative care consultation services (PCCS) can improve a variety of clinical and nonclinical outcomes, little is known about how these services are structured. METHODS: We surveyed all 351 acute care hospitals in California to examine the structure and characteristics of those hospitals with PCCS. RESULTS: We achieved a 92% response rate. Thirty-one percent (n=107) of hospitals reported having a PCCS. Teams commonly included physicians (87%), social workers (80%), spiritual care professionals (77%), and registered nurses (71%). Nearly all PCCS were available on-site during weekday business hours; 50% were available on-site or by phone in the weekday evenings and 54% were available during weekend daytime hours. The PCCS saw an average of 347 patients annually (median=310, standard deviation [SD]=217), or 258 patients per clinical full-time equivalent (FTE; median=250, SD=150.3). Overall, 60% of consultation services reported they are struggling to cope with the workload. On average, patients were in the hospital 5.9 days (median=5.5, SD=3.3) prior to referral to PCCS, and remained in the hospital for 6 days (median=4, SD=7.9) following the initial consultation. Patient and family meetings were an aspect of the consultation in 74% of cases. Overall, 21% of consultation patients were discharged home with hospice services and 25% died in the hospital. CONCLUSIONS: There is variation in how PCCS in California hospitals are structured and in the ways they engage with patients. Ultimately, linking PCCS characteristics and practices to patient and family outcomes will identify best practices that PCCS can use to maximize quality.

Palliative care services in California hospitals: program prevalence and hospital characteristics.

CONTEXT: In 2000, 17% of California hospitals offered palliative care (PC) services. Since then, hospital-based PC programs have become increasingly common, and preferred practices for these services have been proposed by expert consensus. OBJECTIVES: We sought to examine the prevalence of PC programs in California, their structure, and the hospital characteristics associated with having a program. METHODS: A total of 351 acute care hospitals in California completed a survey that determined the presence of and described the structure of PC services. Logistic regression identified hospital characteristics associated with having a PC program. RESULTS: A total of 324 hospitals (92%) responded, of which 44% (n=141) reported having a PC program. Hospitals most likely to have PC programs were large nonprofit facilities that belonged to a health system, had teaching programs, and had participated in a training program designed to promote development of PC services. Investor-owned sites (odds ratio [OR]=0.08; 95% confidence interval [CI]=0.03, 0.2) and city/county facilities (OR=0.06; 95% CI=0.01, 0.3) were less likely to have a PC program. The most common type of PC service was an inpatient consultation service (88%), staffed by a physician (87%), social worker (81%), chaplain (76%), and registered nurse (74%). Most programs (71%, n=86) received funding from the hospital and were expected to meet goals set by the hospital or health system. CONCLUSION: Although the number of hospital-based PC services in California has doubled since 2000, more than half of the acute care hospitals still do not provide PC services. Developing initiatives that target small, public, and investor-owned hospitals may lead to wider availability of PC services.
