    Abstract Ischemic stroke is the leading cause of serious long-term disability and the 5th leading cause of death in the United States. Revascularization of the occluded cerebral artery, either by thrombolysis or endovascular thrombectomy, is the only effective, clinically-approved stroke therapy. Several potentially neuroprotective agents, including glutamate antagonists, anti-inflammatory compounds and free radical scavenging agents were shown to be effective neuroprotectants in preclinical animal models of brain ischemia. However, these compounds did not demonstrate efficacy in clinical trials with human patients following stroke. Proposed reasons for the translational failure include an insufficient understanding on the cellular and molecular pathophysiology of ischemic stroke, lack of alignment between preclinical and clinical studies and inappropriate design of clinical trials based on the preclinical findings. Therefore, novel neuroprotective treatments must be developed based on a clearer understanding of the complex spatiotemporal mechanisms of ischemic stroke and with proper clinical trial design based on the preclinical findings from specific animal models of stroke. We and others have demonstrated the clinical potential for neuregulin-1 (NRG-1) in preclinical stroke studies. NRG-1 significantly reduced ischemia-induced neuronal death, neuroinflammation and oxidative stress in rodent stroke models with a therapeutic window of >13 h. Clinically, NRG-1 was shown to be safe in human patients and improved cardiac function in multisite phase II studies for heart failure. This review summarizes previous stroke clinical candidates and provides evidence that NRG-1 represents a novel, safe, neuroprotective strategy that has potential therapeutic value in treating individuals after acute ischemic stroke.

    Abstract Plantar heel pain is often managed through podiatric and physical therapy interventions. Numerous differential diagnoses may be implicated in patients presenting with plantar heel pain; however, symptoms are often attributed to plantar fasciitis. Abductor hallucis, flexor digitorum brevis, and quadratus plantae share proximal anatomic attachment sites and mechanical function with the plantar fascia. Although these plantar intrinsic muscles each perform isolated digital actions based on fiber orientation and attachment sites, they function collectively to resist depression of the lateral and medial longitudinal arches of the foot. Overuse injury is the primary contributing factor in tendinopathy. The close anatomic proximity and mechanical function of these muscles relative to the plantar fascia suggests potential for proximal plantar intrinsic tendinopathy as a result of repetitive loading during gait and other weightbearing activities. To date, this diagnosis has not been proposed in the scientific literature. Future studies should seek to confirm or refute the existence of proximal plantar intrinsic tendinopathic changes in patients with acute and chronic plantar heel pain through diagnostic imaging studies, analysis of lactate concentration in pathologic versus nonpathologic tendons, and response to specific podiatric and physical therapy interventions germane to tendinopathy of these muscles.

    Abstract In this commentary, we discuss the physiological effects of wearing masks for prolonged periods of time, including special considerations, such as mask wearing among those who engage in exercise training, and concerns for individuals with pre-existing chronic diseases. In healthy populations, wearing a mask does not appear to cause any harmful physiological alterations, and the potentially life-saving benefits of wearing face masks seem to outweigh the documented discomforts (e.g. headaches). However, there continues to be controversy over mask wearing in the United States, even though wearing a mask appears to have only minor physiological drawbacks. While there are minimal physiological impacts on wearing a mask, theoretical evidence suggests that there may be consequential psychological impacts of mask wearing on the basic psychological needs of competence, autonomy, and relatedness. These psychological impacts may contribute to the controversy associated with wearing masks during the COVID-19 pandemic in the United States. After we discuss the physiological impacts of mask wearing, we will discuss psychological effects associated with wearing masks during the COVID-19 pandemic.

    Abstract Identifying novel neuroprotectants that can halt or reverse the neurological effects of stroke is of interest to both clinicians and scientists. We and others previously showed the pre-clinical neuroprotective efficacy of neuregulin-1 (NRG-1) in rats following focal brain ischemia. In this study, we examined neuroprotection by exogenous and endogenous NRG-1 using a mouse model of ischemic stroke. C57BL6 mice were subjected to middle cerebral artery occlusion (MCAO) followed by reperfusion. NRG-1 or vehicle was infused intra-arterially (i.a.) or intravenously (i.v.) after MCAO and before the onset of reperfusion. NRG-1 treatment (16 μg/kg; i.a.) reduced cerebral cortical infarct volume by 72% in mice when delivered post-ischemia. NRG-1 also inhibited neuronal injury as measured by Fluoro Jade B labeling and rescued NeuN immunoreactivity in neurons. Neuroprotection by NRG-1 was also observed in mice when administered i.v. (100 μg/kg) in both male and female mice. We investigated whether endogenous NRG-1 was neuroprotective using male and female heterozygous NRG-1 knockout mice (NRG-1+/-) compared with wild-type mice (WT) littermates. NRG-1+/- and WT mice were subjected to MCAO for 45 min, and infarct size was measured 24 h following MCAO. NRG-1+/- mice displayed a sixfold increase in cortical infarct size compared with WT mice. These results demonstrate that NRG-1 treatment mitigates neuronal damage following cerebral ischemia. We further showed that reduced endogenous NRG-1 results in exacerbated neuronal injury in vivo. These findings suggest that NRG-1 represents a promising therapy to treat stroke in human patients.

    Abstract Participation of Black American older adults in community-engaged research remains challenging in health sciences. The objectives of this study were to describe the specific efforts, successes, and challenges in recruiting Black American older adults in research led by the Health and Wellness in Aging Across the Lifespan core, part of the Virginia Commonwealth University Institute for Inclusion, Inquiry, and Innovation (iCubed). We conducted a cross-case analysis of 6 community-engaged research projects using the community-engaged research continuum model. Successful recruitment strategies comprised a multifaceted approach to community-based collaboration, including a wellness program with a long standing relationship with the community, engaging key stakeholders and a community advisory board, and building a community-based coalition of stakeholders. Posting flyers and modest monetary compensation remain standard recruitment strategies. The cross-case analysis offered critical lessons on the community's nature and level of engagement in research. Relationship building based on trust and respect is essential to solving complex aging issues in the community.

    Abstract Taking a phenomenological approach, this qualitative study describes the lived experiences of low-income older adults during the COVID-19 pandemic. A socio-ecological model was used to organize the five identified themes describing the lived experience: socio-economic context, Black Lives Matter and the politics of race, COVID and polarized views of COVID, interpersonal context (social connections), and individual context (feelings, beliefs, and behaviors). Study findings illustrate the intersectionality of contextual influences on the experience of low-income older adults. Study participants demonstrated remarkable resilience and coping strategies developed in response to the challenges they experienced throughout their lifetime which benefited them when faced with the pandemic, social unrest, and political events that took place in 2020. This study highlights the importance of understanding the larger context of COVID-19 which has significant implications for policy makers and public health leaders.

    Abstract Research suggests high-voltage, pulsed-current electric therapy (HVPC) is safe and effective for treating chronic wounds, and some data suggest silver- and collagen-based dressings may facilitate healing. A combination therapy utilizing both HVPC and silver-collagen dressing may present clinical advantages. To explore the effect of the combined therapy for chronic full-thickness wounds, a prospective, consecutive case series study was conducted. All participants were adults with wounds of at least 6 weeks' duration. After obtaining informed consent, patient and wound characteristics were obtained, wounds were assessed and measured, and patients received 2 to 3 HVPC treatments per week followed by application of the silver- and collagen-based dressing for a period of 2 weeks. Data were analyzed descriptively, and changes in wound size and volume from baseline were analyzed using Wilcoxon Signed Rank Test. The dressings were saturated with normal saline, used simultaneously during the 45-minute HVPC treatment, and left on top of the wound after treatment. The HVPC electro pads (stainless steel electrodes with a sponge interface) also were moistened with normal saline and the cathode placed on top of the wound. If the patient had more than 1 wound on the same leg, the anode was placed on the additional wound (otherwise over the intact skin nearby). Secondary dressings (eg, foam and/ or gauze) were used as clinically appropriate, and a 4-layer compression wrap was used, if indicated, for patients with venous ulcers. Ten (10) patients (3 women, 7 men, 57.30 ± 9.70 years old with 14 wounds of 273.10 ± 292.03 days' duration before study) completed the study and were included in the final analyses. Average wound surface area decreased from 13.78 ± 21.35 cm(2) to 9.07 ± 16.81 cm(2) (42.52% ± 34.16% decrease, P = 0.002) and wound volume decreased from 3.39 ± 4.31 cm(3) to 1.28 ± 2.25 cm(3) (66.84% ± 25.07% decrease, P = 0.001). One (1) patient was discharged with complete wound closure. No serious adverse events were noted, but a diagnosis of osteomyelitis in 1 patient and increased pain in a patient with significant Reynaud's syndrome suggest clinicians should be cautious using HVPC in these instances. The combined intervention utilizing both HVPC and silver-collagen dressing was effective in the treatment of chronic fullthickness wounds in this patient population. Controlled clinical studies of longer duration are needed to further explore the safety, effectiveness, and efficacy of this treatment.
