RESUMEN

Overcoming barriers to accessing health services is especially difficult in minority groups and rural populations. Nontraditional sites for delivering health care in the United States offer opportunities to reduce health disparities. Actually realizing these reductions, however, requires health systems to partner with trusted, convenient community services where people who experience health disparities spend substantial time - and, in turn, for those trusted service sites to seek partnerships with health systems. Libraries, places of worship, laundromats, barber shops, fire departments, dollar stores, shopping malls, and other local sites offer the chance to serve people who most need supportive health services in places they already trust enough to meet their other basic needs. Examples of such community health partnerships are cropping up around the United States, with some showing great success, although typically on a small scale. So, how will these small-scale successes proliferate? The answer lies in the "nuts and bolts" of implementation logistics. First, successful community health partnerships must be cultivated so that health systems and community venues co-design programs with direct input from community members. Second, entities seeking partnerships must explore multiple ways to procure funding. Third, coordinated efforts must be made to create awareness among the population a program seeks to serve. Fourth, day-to-day operations may need to be conducted in novel ways, especially considering physical, technological, and other implementation challenges that most nontraditional sites would face. As such successes proliferate and garner publicity, community health partnerships will be formed in greater numbers of unexpected places, with an ever-growing potential to reduce health disparities.

RESUMEN

Identifying novel therapeutic approaches to promote recovery of neurological functions following spinal cord injury (SCI) remains a great unmet need. Nociceptive signaling in the acute phase of SCI has been shown to inhibit recovery of locomotor function and promote the development of chronic neuropathic pain. We therefore hypothesized that inhibition of nociceptive signaling in the acute phase of SCI might improve long-term functional outcomes in the chronic phase of injury. To test this hypothesis, we took advantage of a selective strategy utilizing AAV6 to deliver inhibitory (hM4Di) Designer Receptors Exclusively Activated by Designer Drugs (DREADDs) to nociceptors of the L4-L6 dorsal root ganglia to evaluate the effects of transient nociceptor silencing on long-term sensory and motor functional outcomes in a rat thoracic contusion SCI model. Following hM4Di-mediated nociceptor inhibition from 0-14 days post-SCI, we conducted behavioral assessments until 70 days post-SCI, then performed histological assessments of lesion severity and axon plasticity. Our results show highly selective expression of hM4Di within small diameter nociceptors including calcitonin gene-related peptide (CGRP)+ and IB4-binding neurons. Expression of hM4Di in less than 25% of nociceptors was sufficient to increase hindlimb thermal withdrawal latency in naïve rats. Compared with subjects who received AAV-yellow fluorescent protein (YFP; control), subjects who received AAV-hM4Di exhibited attenuated thermal hyperalgesia, greater coordination, and improved hindlimb locomotor function. However, treatment did not impact the development of cold allodynia or mechanical hyperalgesia. Histological assessments of spinal cord tissue suggested trends toward reduced lesion volume, increased neuronal sparing and increased CGRP+ axon sprouting in hM4Di-treated animals. Together, these findings suggest that nociceptor silencing early after SCI may promote beneficial plasticity in the acute phase of injury that can impact long-term functional outcomes, and support previous work highlighting primary nociceptors as possible therapeutic targets for pain management after SCI.

RESUMEN

Hb9 (Mnx1) is a transcription factor described as a spinal cord motor neuron (MN)-specific marker and critical factor for the postmitotic specification of these cells. To date, expression of Hb9 in other cell types has not been reported. We performed a fate-mapping approach to examine distributions of Hb9-expressing cells and their progeny ("Hb9-lineage cells") within the embryonic and adult spinal cord of Hb9cre;Ai14 mice. We found that Hb9-lineage cells are distributed in a gradient of increasing abundance throughout the rostrocaudal spinal cord axis during embryonic and postnatal stages. Furthermore, although the majority of Hb9-lineage cells at cervical spinal cord levels are MNs, at more caudal levels, Hb9-lineage cells include small-diameter dorsal horn neurons, astrocytes, and oligodendrocytes. In the peripheral nervous system, we observed a similar phenomenon with more abundant Hb9-lineage Schwann cells in muscles of the lower body versus upper body muscles. We cultured spinal cord progenitors in vitro and found that gliogenesis was increased by treatment with the caudalizing factor FGF-8B, while glial tdTomato expression was increased by treatment with both FGF-8B and GDF-11. Together, these observations suggest that early and transient expression of Hb9 in spinal cord neural progenitors may be induced by caudalizing factors such as FGF and GDF signaling. Furthermore, our work raises the possibility that early Hb9 expression may influence the development of spinal cord macroglia and Schwann cells, especially at caudal regions. Together, these findings highlight the importance of using caution when designing experiments using Hb9cre mice to perform spinal cord MN-specific manipulations.

RESUMEN

Despite advancement of neural progenitor cell transplantation to spinal cord injury clinical trials, there remains a lack of understanding of how biological sex of transplanted cells influences outcomes after transplantation. To address this, we transplanted GFP-expressing sex-matched, sex-mismatched, or mixed donor cells into sites of spinal cord injury in adult male and female mice. Biological sex of the donor cells does not influence graft neuron density, glial differentiation, formation of the reactive glial cell border, or graft axon outgrowth. However, male grafts in female hosts feature extensive hypervascularization accompanied by increased vascular diameter and perivascular cell density. We show greater T-cell infiltration within male-to-female grafts than other graft types. Together, these findings indicate a biological sex-specific immune response of female mice to male donor cells. Our work suggests that biological sex should be considered in the design of future clinical trials for cell transplantation in human injury.

RESUMEN

Outsourcing in health care has become increasingly common as health system administrators seek to enhance profitability and efficiency while maintaining clinical excellence. When clinical services are outsourced, however, the outsourcing organization relinquishes control over its most important service value: high-quality patient care. Farming out work to an external service provider can have many unintended results, including inconsistencies in standards of care; harmful medical errors; declines in patient and employee satisfaction; and damage to clinicians' morale and income, and to the health organization's culture, reputation, and long-term financial performance. Research on outsourcing in the areas of emergency medicine, radiology, laboratory services, and environmental services provides concerning evidence of potentially large downsides when outsourcing is driven by short-term cost concerns or is planned without diligently considering all of the ramifications of not keeping key clinical and nonclinical services in-house. To better equip health system leaders for decision-making about outsourcing, we examine this body of literature, identify common pitfalls of outsourcing in specific clinical and nonclinical health services and scenarios, explore alternatives to outsourcing, and consider how outsourcing (when necessary) can be done in a strategic manner that does not compromise the values of the organization and its commitment to patients.

RESUMEN

When people think about trust in the context of health care, they typically focus on whether patients trust the competence of doctors and other health professionals. But for health care to reach its full potential as a service, trust must also include the notion of partnership, whereby patients see their clinicians as reliable, caring, shared decision-makers who provide ongoing "healing" in its broadest sense. Four interrelated service-quality concepts are central to fostering trust-based partnerships in health care: empathetic creativity, discretionary effort, seamless service, and fear mitigation. Health systems and institutions that prioritize trust-based partnerships with patients have put these concepts into practice using several concrete approaches: investing in organizational culture; hiring health professionals for their values, not just their skills; promoting continuous learning; attending to the power of language in all care interactions; offering patients "go-to" sources for timely assistance; and creating systems and structures that have trust built into their very design. It is in the real-world implementation of trust-based partnership that health care can reclaim its core mission.

RESUMEN

OBJECTIVE: Oxidative stress is a central event linked with endothelial dysfunction and inflammation in several vascular pathologies, marked by over-production of ROS and concomitant decreases in antioxidants, for example GSH. Here, we distinguish endothelial oxidative stress regulation and associated functional disparities in the two main vascular conduits, (arteries and veins) following decreases in GSH. METHODS: MAECs and VCECs were used as models of arterial and venular endothelium, respectively, and BSO (0-100 µmol/L) was used to indirectly increase cellular oxidative stress. Inflammatory responses were measured using immune cell attachment and immunoblotting for endothelial cell adhesion molecule (ICAM-1, VCAM-1) expression, altered cell proliferation, and wound healing. RESULTS: MAECs and VCECs exhibited differential responses to oxidative stress produced by GSH depletion with VCECs exhibiting greater sensitivity to oxidative stress. Compared to MAECs, VCECs showed a significantly increased inflammatory profile and a decreased proliferative phenotype in response to decreases in GSH levels. CONCLUSIONS: Arterial and venous endothelial cells exhibit differential responses to oxidant stress, and decreases in GSH:GSSG are more exacerbated in venous endothelial cells. Specific pathogenesis in these vascular conduits, with respect to oxidant stress handling, warrants further study, especially considering surgical interventions such as Coronary artery bypass grafting that use both interchangeably.
