Longitudinal Monitoring of Clinician-Patient Video Visits During the Peak of the COVID-19 Pandemic: Adoption and Sustained Challenges in an Integrated Health Care Delivery System.

BACKGROUND: Numerous prior opinion papers, administrative electronic health record data studies, and cross-sectional surveys of telehealth during the pandemic have been published, but none have combined assessments of video visit success monitoring with longitudinal assessments of perceived challenges to the rapid adoption of video visits during the pandemic. OBJECTIVE: This study aims to quantify (1) the use of video visits (compared with in-person and telephone visits) over time during the pandemic, (2) video visit successful connection rates, and (3) changes in perceived video visit challenges. METHODS: A web-based survey was developed for the dual purpose of monitoring and improving video visit implementation in our health care system during the COVID-19 pandemic. The survey included questions regarding rates of in-person, telephone, and video visits for clinician-patient encounters; the rate of successful connection for video visits; and perceived challenges to video visits (eg, software, hardware, bandwidth, and technology literacy). The survey was distributed via email to physicians, advanced practice professionals, and clinicians in May 2020. The survey was repeated in March 2021. Differences between the 2020 and 2021 responses were adjusted for within-respondent correlation across surveys and tested using generalized estimating equations. RESULTS: A total of 1126 surveys were completed (511 surveys in 2020 and 615 surveys in 2021). In 2020, only 21.7% (73/336) of clinicians reported no difficulty connecting with patients during video visits and 28.6% (93/325) of clinicians reported no difficulty in 2021. The distribution of the percentage of successfully connected video visits ("Over the past two weeks of scheduled visits, what percentage did you successfully connect with patients by video?") was not significantly different between 2020 and 2021 (P=.74). Challenges in conducting video visits persisted over time. Poor connectivity was the most common challenge reported by clinicians. This response increased over time, with 30.5% (156/511) selecting it as a challenge in 2020 and 37.1% (228/615) in 2021 (P=.01). Patients not having access to their electronic health record portals was also a commonly reported challenge (109/511, 21.3% in 2020 and 137/615, 22.3% in 2021, P=.73). CONCLUSIONS: During the pandemic, our health care delivery system rapidly adopted synchronous patient-clinician communication using video visits. As experience with video visits increased, the reported failure rate did not significantly decline, and clinicians continued to report challenges related to general network connectivity and patient access to technology.

Systemic administration of a ß2-adrenergic receptor agonist reduces mechanical allodynia and suppresses the immune response to surgery in a rat model of persistent post-incisional hypersensitivity.

Beta 2 adrenergic receptor (ß2 AR) activation in the central and peripheral nervous system has been implicated in nociceptive processing in acute and chronic pain settings with anti-inflammatory and anti-allodynic effects of ß2-AR mimetics reported in several pain states. In the current study, we examined the therapeutic efficacy of the ß2-AR agonist clenbuterol in a rat model of persistent postsurgical hypersensitivity induced by disruption of descending noradrenergic signaling in rats with plantar incision. We used growth curve modeling of ipsilateral mechanical paw withdrawal thresholds following incision to examine effects of treatment on postoperative trajectories. Depletion of spinal noradrenergic neurons delayed recovery of hypersensitivity following incision evident as a flattened slope compared to non-depleted rats (-1.8 g/day with 95% CI -2.4 to -1.085, p < 0.0001). Chronic administration of clenbuterol reduced mechanical hypersensitivity evident as a greater initial intercept in noradrenergic depleted (6.2 g with 95% CI 1.6 to 10.8, p = 0.013) and non-depleted rats (5.4 g with 95% CI 1.2 to 9.6, p = 0.018) with plantar incision compared to vehicle treated rats. Despite a persistent reduction in mechanical hypersensitivity, clenbuterol did not alter the slope of recovery when modeled over several days (p = 0.053) or five weeks in depleted rats (p = 0.64). Systemic clenbuterol suppressed the enhanced microglial activation in depleted rats and reduced the density of macrophage at the site of incision. Direct spinal infusion of clenbuterol failed to reduce mechanical hypersensitivity in depleted rats with incision suggesting that beneficial effects of ß2-AR stimulation in this model are largely peripherally mediated. Lastly, we examined ß2-AR distribution in the spinal cord and skin using in-situ hybridization and IHC. These data add to our understanding of the role of ß2-ARs in the nervous system on hypersensitivity after surgical incision and extend previously observed anti-inflammatory actions of ß2-AR agonists to models of surgical injury.

Management of Acute Central Retinal Artery Occlusion, a "Retinal Stroke": An Institutional Series and Literature Review.

OBJECTIVES: Acute central retinal artery occlusion (CRAO) is an ophthalmologic emergency that often results in permanent vision loss. Over 25% are associated with acute cerebral ischemia. In the absence of existing Level I treatment options, this study aims to examine institutional practice patterns and review the literature to develop a formalized approach to the treatment of CRAO in the era of ischemic stroke protocols. MATERIALS AND METHODS: This is a retrospective review of institutional practices in the workup and treatment of patients diagnosed with acute non-arteritic (NA) CRAO at a single center from January 2017 to August 2020. RESULTS: Of 91 patients managed for acute NA-CRAO, 62.6% were male and average age was 66.4 years. Only 20.9% of patients presented within 4 h of symptom onset. 12.1% of patients had evidence of acute stroke on MRI, and 27.5% had ipsilateral internal carotid artery stenosis >50%. Half (52.7%) did not receive any acute treatment for CRAO, excluding antiplatelet/anticoagulation. 48.5% of patients undergoing acute medical treatment had improved visual acuity compared to 29.4% without treatment (p=0.14). CONCLUSIONS: There is a lack of clear protocol for the management of NA-CRAO. While not reaching statistical significance, our experience mirrors the literature with patients undergoing medical treatment demonstrating improved visual acuity over those without treatment. Given the presence of acute ischemic stroke, carotid disease, and/or stroke risk factors in over 25% of patients with CRAO, multidisciplinary involvement and modern stroke algorithms should be considered for this disease.

Intensive care unit admission is not necessary after venous sinus stenting.

BACKGROUND: Venous sinus stenting (VSS) has emerged as a safe and effective treatment option for idiopathic intracranial hypertension. Many physicians routinely admit patients to the intensive care unit (ICU) for close monitoring, but little data exists on whether this is necessary. METHODS: Electronic medical records of consecutive patients who underwent VSS by the senior author from 2016 to 2022 at a single center were reviewed. RESULTS: 214 patients were included. The mean (SD) age was 35.5 (11.6) and 196 (91.6%) patients were female. A total of 166 (77.6%) patients underwent transverse sinus stenting alone; 9 (4.2%) underwent superior sagittal sinus (SSS) stenting alone, 37 (17.3) concomitant transverse and SSS stenting, and 2 (0.9%) underwent stenting at alternate sites. All patients were planned admission to the regular ward (27.6%) or day hospital (72.4%). Twenty (9.3%) patients were discharged to home the same day as the procedure and 182 (85%) patients were discharged the following day. Major periprocedural complications were identified in 2 (0.93%) patients and minor complications were identified in 16 (7.4%). Only one patient with a subdural hematoma identified in the post-anesthesia care unit (PACU) had care escalated to the ICU. No severe complications were identified after the PACU stay. During the next 48 hours after discharge, 4 (1.9%) patients returned to any emergency room to be evaluated without requiring readmission. CONCLUSION: Routine ICU admission following uncomplicated VSS is unnecessary. Overnight admission to a low-acuity ward, or even same-day discharge in select patients, appears to be a safe and cost-effective strategy.

Fueling the future of neurosurgery: increasing trends in female enrollment expanding the neurosurgical workforce from 2010 to 2019.

OBJECTIVE: Regular reporting on recruitment of women into neurosurgery is a mechanism to track the progress of minority inclusion and diversity. For more than 20 years, half of US medical students have been women, yet a disproportionate minority pursue a career in neurosurgery. The authors previously published data tracking women in neurosurgery for the prior decade from 2000 to 2009, which showed an increasing match rate of women over time, from 18 women matched at the beginning of the decade to 36 matched at the end. They now present updated data on the matriculation of women into neurosurgical residencies across the most recent decade, from 2010 to 2019. METHODS: Public databases from the Association of American Medical Colleges were analyzed for applicants to neurosurgical residency from 2010 to 2019. Demographic data for those matched was obtained from the American Medical Association Masterfile and analyzed for year of match and gender. Secondary outcomes included program location, age, and gap year(s) between medical school and residency. RESULTS: Women made up 18.8% (394/2094) of residents matched into neurosurgery from 2010 to 2019, compared to 12% during the previous decade. There was an increase in overall match rate of 2.2% per year (male + female) from 2010 to 2019, representing the predicted need for expansion of the neurosurgical workforce to meet national needs. Women made up the majority of this expansion, rising by 5.5% over the time period (p = 0.002), compared to men increasing by 1.4% over the time period (p = 0.096). The percentage of women applicants who matched was 34.4%, compared to men at 38.6% (p = 0.009). There was no significant difference in gender with regard to age, number of gap years, or program location. CONCLUSIONS: The number of women matching into neurosurgery has continued to increase across the last 2 decades. Despite this, there remains significant disparity between the number of men and women matching into neurosurgery. Ongoing mitigation of barriers to recruitment of women into neurosurgery is critical. The authors' data highlight the fact that women are important to fueling the expansion of the neurosurgical workforce.

Redefining treatment expectations: exploring mid- and long-term outcomes of venous sinus stenting in idiopathic intracranial hypertension.

BACKGROUND: Venous sinus stenting (VSS) is recognized as a safe and effective intervention for medically-refractory idiopathic intracranial hypertension (IIH). However, its long-term efficacy remains uncertain. METHODS: This retrospective review analyzed a single-center database of adult patients with severe, medically-refractory IIH, who underwent VSS and had minimum 3-month follow-up (FU). Patients were divided into three groups based on post-stenting symptom trajectories: group 1 (sustained improvement without relapse), group 2 (temporary improvement with relapse), and group 3 (no improvement). RESULTS: Of 178 patients undergoing VSS, the majority were female (94%), with a median opening pressure (OP) of 31 cm H2O and trans-stenosis gradient of 14 mm Hg. Of these, 153 (86%) received transverse sinus (TS) stenting, and 19 (11%) underwent concurrent TS and superior sagittal sinus stenting. At a mean FU of 166 days, 53 patients (30%) showed long-term improvement without relapse (group 1). Symptomatic recurrence was noted in 101 patients (57%; group 2) within a mean FU of 390 days. Despite recurrent headache and tinnitus, the average OP reduction was 9.6 cm H2O on repeat lumbar puncture, with 75% showing papilledema improvement or resolution post-VSS. Only 17% required further surgical intervention. CONCLUSIONS: The most common clinical outcome post-VSS in IIH patients is initial symptomatic improvement followed by symptom recurrence in about 60% at a mean of 274 days, despite a consistent intracranial pressure reduction. These findings can guide physicians in setting realistic expectations with patients regarding VSS outcomes.

Surgical management of spinal multiple myeloma: insights from the National Inpatient Sample database.

Background: Management of multiple myeloma (MM) of the spine includes a multimodal approach consisting of chemotherapy, bisphosphonates, radiation, and surgical intervention. This study aims to explore the trends in surgical treatment of MM including hospital costs, odds of complications, and the impact of patient comorbidities on the risk of complications using the National Inpatient Sample (NIS) database. Methods: The NIS was queried for patients with MM and plasmacytoma of the spine who underwent surgical intervention between 2005 and 2014. Rates of spinal decompression, spinal stabilization with or without decompression, and vertebral augmentation were analyzed. The effect of various patient characteristics on outcome was analyzed by multivariate analysis and stratified by surgical procedure. Results: Vertebral augmentation (9,643, 65.7%) was the most commonly performed procedure, followed by spinal stabilization with or without decompression (4,176, 28.4%) and then decompression alone (868, 5.9%). The total population-adjusted rate of surgical management for MM remained stable during the study period, while the rate of spinal stabilization increased (P<0.001) and the rate of vertebral augmentation decreased (P=0.01). Vertebral augmentation was associated with shorter inpatient hospital stay, lower total cost, and higher likelihood of discharging to home. The complication rate increased over time for vertebral augmentation procedures (P<0.001) while spinal stabilization and decompression complication rates remained stable. The complication rate for all procedures was higher in male patients (P<0.001) and increased with the number of patient comorbidities (P<0.001). Conclusions: Spinal surgery seems to be increasing for the management of spinal MM in the inpatient setting, while the rate of vertebral augmentation is decreasing. Vertebroplasty and similar palliative procedures may continue to decrease as advancements in surgical technology and technique allow for safer surgical intervention. The decision to employ aggressive surgical intervention, however, must always take into account the patient's comorbidities, overall systemic disease burden, and the potential for significant enhancement in meaningful clinical outcome.

The correlation between intracranial pressure and venous sinus pressures changes after venous sinus stenting.

BACKGROUND: The pathophysiology of idiopathic intracranial hypertension (IIH) and other cerebral venous outflow disorders (CVD) has largely been unexplored. While a correlation between venous sinus pressure and opening pressure (OP) has been previously noted, there are limited data on this relationship in patients with prior venous sinus stenting (VSS). METHODS: A single center retrospective chart review was conducted on CVD patients who underwent diagnostic cerebral venography with manometry followed immediately by lateral decubitus lumbar puncture, from 2016 to 2024. RESULTS: 206 patients underwent 216 total procedures and were included. Among all patients, there was a moderate nearly one-to-one correlation between OP and torcular or superior sagittal sinus (SSS) pressures. Thirty-two patients underwent testing after having undergone VSS. Patients with previous VSS showed a significantly altered relationship between venous pressures and OP, whereby as venous sinus pressures increased, OP increased more gradually in previously stented patients compared with non-stented patients. For example, when OP was fixed at 21 mm Hg and body mass index at 30 kg/m2, predicted mean SSS pressure was 19.47 mm Hg in non-stented patients versus 16.91 mm Hg in stented patients. CONCLUSION: This study confirmed a strong relationship between OP and venous sinus pressure in CVD patients. However, patients with previous VSS demonstrated an altered relationship with higher CSF pressures relative to venous pressures compared with naïve patients. This finding may have important clinical implications in the management of IIH patients.

Sexual Orientation and Gender Identity Data Collection in Cancer Care: A Nationwide Landscape Assessment Update.

PURPOSE: Routine collection of sexual orientation (SO) and gender identity (GI; collectively SOGI) in cancer clinics advances cancer care equity. METHODS: In 2022, NCI Community Oncology Research Program (NCORP) practice groups were asked about routine collection of SOGI data in the electronic health record. The proportions of practice groups reporting collection of SO and/or GI data were calculated, and practice group characteristics were assessed for associations. RESULTS: Of 271 practice groups nationwide, 42% (n = 112) collect SO data, 58% (n = 157) collect GI data, and 35% (n = 96) collect both. In multivariate analyses, SO data collection was associated with practice groups having minority outreach staff (odds ratio [OR], 2.07 [95% CI, 1.12 to 3.81]; P = .02); GI data collection was associated with practice groups located in the Northeastern United States (OR, 2.08 [95% CI, 0.73 to 5.91]; P = .045), and those with a higher proportion of new patients who were White (OR, 1.02 [95% CI, 1.01 to 1.04]; P < .001). Practice groups in the South were least likely to collect SOGI data (OR, 0.49 [95% CI, 0.26 to 0.94]; P = .004). There were no statistically significant differences in SO and/or GI collection on the basis of the practice group's proportion of Medicaid/Medicare patients, number of new patients with cancer per year, or practice ownership. CONCLUSION: Slightly over one third of NCORP practice groups report routinely collecting SOGI data. There are regional differences in data collection, underscoring the need to craft targeted, region-specific interventions focused on boosting the capture and recording of SOGI data in an affirming manner.

Availability of cancer survivorship support services across the National Cancer Institute Community Oncology Research Program network.

BACKGROUND: National cancer organizations recommend provision of nutrition, physical activity, and mental health supportive services to cancer survivors. However, the availability of these services across diverse community oncology settings remains unclear. METHODS: The National Cancer Institute Community Oncology Research Program (NCORP) is a national network of community oncology practices engaged in cancer research. The 2022 NCORP Landscape Assessment (5UG1CA189824) assessed individual practices' establishment of survivorship clinics and nutrition, physical activity, and mental health services, resources, and/or referrals. Descriptive statistics summarized and logistic regression quantified the association between services, practice, and patient characteristics. RESULTS: Of 46 NCORP community sites, 45 (98%) responded to the survey, representing 259 adult practice groups. A total of 41% had a survivorship clinic; 96% offered mental health, 94% nutrition, and 53% physical activity services, resources, and/or referrals. All 3 services were offered in various formats (eg, in-house, referrals, education) by 51% and in-house only by 25% of practices. Practices with advanced practice providers were more likely to have a survivorship clinic (odds ratio [OR] = 3.19, 95% confidence interval [CI] = 1.04 to 9.76). Practices with at least 30% Medicare patients (OR = 2.54, 95% CI = 1.39 to 4.66) and more oncology providers (OR = 1.02, 95% CI = 1.01 to 1.04) were more likely to have all 3 services in any format. Practices with at least 30% Medicare patients (OR = 3.41, 95% CI = 1.50 to 7.77) and a survivorship clinic (OR = 2.84, 95% CI = 1.57 to 5.14) were more likely to have all 3 services in-house. CONCLUSIONS: Larger oncology practices and those caring for more survivors on Medicare provided more supportive services, resources, and/or referrals. Smaller practices and those without survivorship clinics may need strategies to address potential gaps in supportive services.

Delayed Imaging Changes 18 Months or Longer After Stereotactic Radiosurgery for Brain Metastases: Necrosis or Progression.

OBJECTIVE: Imaging changes after stereotactic radiosurgery (SRS) can occur for years after treatment, although the available data on the incidence of tumor progression and adverse radiation effects (ARE) are generally limited to the first 2 years after treatment. METHODS: A single-institution retrospective review was conducted of patients who had >18 months of imaging follow-up available. Patients who had ≥1 metastatic brain lesions treated with Gamma Knife SRS were assessed for the time to radiographic progression. Those with progression ≥18 months after the initial treatment were included in the present study. The lesions that progressed were characterized as either ARE or tumor progression based on the tissue diagnosis or imaging characteristics over time. RESULTS: The cumulative incidence of delayed imaging radiographic progression was 35% at 5 years after the initial SRS. The cumulative incidence curves of the time to radiographic progression for lesions determined to be ARE and lesions determined to be tumor progression were not significantly different statistically. The cumulative incidence of delayed ARE and delayed tumor progression was 17% and 16% at 5 years, respectively. Multivariate analysis indicated that the number of metastatic brain lesions present at the initial SRS was the only factor associated with late radiographic progression. CONCLUSIONS: The timing of late radiographic progression does not differ between ARE and tumor progression. The number of metastatic brain lesions at the initial SRS is a risk factor for late radiographic progression.

Addressing social needs in oncology care: another research-to-practice gap.

Social determinants of health and unmet social needs are directly related to cancer outcomes, from diagnosis to survivorship. If identified, unmet social needs can be addressed in oncology care by changing care plans in collaboration with patients' preferences and accounting for clinical practice guidelines (eg, reducing the frequency of appointments, switching treatment modalities) and connecting patients to resources within healthcare organizations (eg, social work support, patient navigation) and with community organizations (eg, food banks, housing assistance programs). Screening for social needs is the first step to identifying those who need additional support and is increasingly recognized as a necessary component of high-quality cancer care delivery. Despite evidence about the relationship between social needs and cancer outcomes and the abundance of screening tools, the implementation of social needs screening remains a challenge, and little is known regarding the adoption, reach, and sustainability of social needs screening in routine clinical practice. We present data on the adoption and implementation of social needs screening at two large academic cancer centers and discuss three challenges associated with implementing evidence-based social needs screening in clinical practice: (1) identifying an optimal approach for administering social needs screening in oncology care, (2) adequately addressing identified unmet needs with resources and support, and (3) coordinating social needs screening between oncology and primary care.

A qualitative study of stakeholders' experiences with and acceptability of a technology-supported health coaching intervention (SHARE-S) delivered in coordination with cancer survivorship care.

PURPOSE: Healthy cancer survivorship involves patients' active engagement with preventative health behaviors and follow-up care. While clinicians and patients have typically held dual responsibility for activating these behaviors, transitioning some clinician effort to technology and health coaches may enhance guideline implementation. This paper reports on the acceptability of the Shared Healthcare Actions & Reflections Electronic systems in survivorship (SHARE-S) program, an entirely virtual multicomponent intervention incorporating e-referrals, remotely-delivered health coaching, and automated text messages to enhance patient self-management and promote healthy survivorship. METHODS: SHARE-S was evaluated in single group hybrid implementation-effectiveness pilot study. Patients were e-referred from the clinical team to health coaches for three health self-management coaching calls and received text messages to enhance coaching. Semi-structured qualitative interviews were conducted with 21 patient participants, 2 referring clinicians, and 2 health coaches to determine intervention acceptability (attitudes, appropriateness, suitability, convenience, and perceived effectiveness) and to identify important elements of the program and potential mechanisms of action to guide future implementation. RESULTS: SHARE-S was described as impactful and convenient. The nondirective, patient-centered health coaching and mindfulness exercises were deemed most acceptable; text messages were less acceptable. Stakeholders suggested increased flexibility in format, frequency, timing, and length of participation, and additional tailored educational materials. Patients reported tangible health behavior changes, improved mood, and increased accountability and self-efficacy. CONCLUSIONS: SHARE-S is overall an acceptable and potentially effective intervention that may enhance survivors' self-management and well-being. Alterations to tailored content, timing, and dose should be tested to determine impact on acceptability and outcomes.

Defining the Role of the Advanced Practice Provider Within the National Cancer Institute Community Oncology Research Program.

PURPOSE: Oncology advanced practice providers (APPs), including nurse practitioners, clinical nurse specialists, physician assistants, and clinical pharmacists, contribute significantly to quality cancer care. Understanding the research-related roles of APPs in the National Cancer Institute's (NCI) Community Oncology Research Program (NCORP) could lead to enhanced protocol development, trial conduct, and accrual. METHODS: The 2022 NCORP Landscape Assessment Survey asked two questions about the utilization and roles of APPs in the NCORP. RESULTS: A total of 271 practice groups completed the 2022 survey, with a response rate of 90%. Of the 259 nonpediatric exclusive practice groups analyzed in this study, 92% used APPs for clinical care activities and 73% used APPs for research activities. APPs most often provided clinical care for patients enrolled in trials (97%), followed by assistance with coordination (65%), presenting/explaining clinical trials (59%), screening patients (49%), ordering investigational drugs (37%), and consenting participants (24%). Some groups reported APPs as an enrolling investigator (18%) and/or participating in institutional oversight/selection of trials (15%). Only 5% of NCORP sites reported APPs as a site primary investigator for trials, and very few (3%) reported APPs participating in protocol development. CONCLUSION: Practice groups report involving APPs in clinical research within the NCORP network; however, opportunities for growth exists. As team-based care has enhanced clinical practice in oncology, this same approach can be used to enhance successful research. Suggested strategies include supporting APP research-related time, recognition, and education. The findings of this survey and subsequent recommendations may be applied to all adult oncology practices that participate in clinical research.

Coil embolization alone appears sufficient for middle meningeal artery embolization.

BACKGROUND: Middle meningeal artery embolization (MMAE) has shown promise as an alternative treatment for chronic subdural hematoma (cSDH); however, the most effective procedural technique is debated. We sought to assess the safety and efficacy of coil embolization as a stand-alone technique for MMAE in cSDH. METHODS: A single-center retrospective analysis was performed of patients who underwent MMAE for chronic SDH with coil embolization alone. RESULTS: Forty-five patients were included in the study. All underwent successful stand-alone coil MMAE, of which 51.1% were bilateral. Indications for MMAE were varied, but 13.3% of patients required ongoing anticoagulation and another 11.1% had severe thrombocytopenia. Conscious sedation or no sedation was used in 73.2% of patients; 10 patients (22.2%) were scheduled electively and discharged same day. There were no severe or minor procedural complications identified. Of the 45 patients, only 3 (6.6%) underwent unplanned repeat surgical intervention: one patient developed a large recurrence at eight weeks after MMAE and underwent burr hole drainage; the second patient received burr hole drainage prior to MMAE but needed repeat burr hole drainage two weeks later due to residual; the third patient received two burr hole drainages at two and three weeks post MMAE due to persistent disease. CONCLUSION: Stand-alone MMAE with coiling can be performed under conscious sedation as an outpatient procedure and may be sufficient to prevent cSDH recurrence in most cases without the need for particle penetration of cSDH microvascular beds. Larger confirmatory studies are necessary.

A national survey of venous sinus stenting practices for idiopathic intracranial hypertension.

BACKGROUND: Little is currently known about physician opinions and preferences on venous sinus stenting (VSS) for idiopathic intracranial hypertension (IIH), practice patterns, or clinical volumes. METHODS: A 19 question online survey was designed and distributed to physician members of the Society of Neurointerventional Surgery (SNIS). RESULTS: A total of 107 individual survey responses were obtained (14% of SNIS members). The majority of respondents (85%) indicated that they had performed at least one VSS procedure independently during their careers. Mean (SD) and median (range) career case volumes were 20.9 (33.8) and 10.0 (0.0-200.0), respectively. On a 1-10 scale, most respondents reported a high level of interest in treating IIH patients with VSS (median 8), a high level of comfort/expertise in treating IIH patients with VSS (median 9), and that VSS was effective in the long term reduction of symptoms and papilledema in IIH patients (median 8). Fifty-nine per cent of respondents reported increasing VSS volumes compared with previous years. A major complication during a VSS procedure, including two deaths, was reported by 11% of respondents. CONCLUSIONS: This is the first study designed to understand the opinions and practices of neurointerventionists regarding VSS for IIH. Overall physician opinion on VSS was quite positive, supported by increasing procedural volumes reported by most over the past few years. However, only a small percentage of respondents had substantial experience with VSS and major complications were not rare.

A descriptive study of venous pressures and gradients while awake and both pre- and post-stent under anesthesia in patients with idiopathic intracranial hypertension.

BACKGROUND: This study aims to explore factors that affect venous sinus pressures and associated gradients while awake and under general anesthesia (GA) both before and after venous sinus stenting (VSS) in patients with idiopathic intracranial hypertension (IIH). METHODS: A retrospective analysis was performed examining pressures and gradients in patients with IIH having undergone awake venography followed by VSS under GA. RESULTS: 174 patients were included. Compared with awake, GA superior sagittal sinus (SSS) pressures were 2.6 mmHg lower (p=0.01) resulting in a total cranial gradient reduction of 2.5 mmHg (p=0.002). The transverse-sigmoid gradient, the most commonly stented segment, did not differ under the two conditions (p=0.30). Regression analyses demonstrated that body mass index, gender, blood pressure, and end-tidal carbon dioxide content significantly affected venous pressures (all p<0.05). After stenting, mean total cranial gradients decreased by 13.2 mmHg while skull base gradients increased by 0.8 mmHg. Stenting resulted in an 84% mean reduction in the target gradient and a mean decrease in SSS pressures by 78% of the target gradient. When cardiopulmonary and anesthetic factors were optimized, GA had a limited effect on the target gradient in most patients (p=0.88). CONCLUSIONS: This study is the largest series to date to report on cerebral venous pressure measurements and gradients recorded while awake and under GA both before and after VSS for IIH. In a well-controlled cardiorespiratory and anesthetic setting, GA venography may provide information that is not substantially inequivalent to that obtained while awake.

Evaluation of pain related behaviors and disease related outcomes in an immunocompetent mouse model of prostate cancer induced bone pain.

Cancer-induced bone pain (CIBP) is the most common and devastating symptom of bone metastatic cancer that substantially disrupts patients' quality of life. Currently, there are few effective analgesic treatments for CIBP other than opioids which come with severe side effects. In order to better understand the factors and mechanisms responsible for CIBP it is essential to have clinically relevant animal models that mirror pain-related symptoms and disease progression observed in patients with bone metastatic cancer. In the current study, we characterize a syngeneic mouse model of prostate cancer induced bone pain. We transfected a prostate cancer cell line (RM1) with green fluorescent protein (GFP) and luciferase reporters in order to visualize tumor growth longitudinally in vivo and to assess the relationship between sensory neurons and tumor cells within the bone microenvironment. Following intra-femoral injection of the RM1 prostate cancer cell line into male C57BL/6 mice, we observed a progressive increase in spontaneous guarding of the inoculated limb between 12 and 21 days post inoculation in tumor bearing compared to sham operated mice. Daily running wheel performance was evaluated as a measure of functional impairment and potentially movement evoked pain. We observed a progressive reduction in the distance traveled and percentage of time at optimal velocity between 12 and 21 days post inoculation in tumor bearing compared to sham operated mice. We utilized histological, radiographic and µCT analysis to examine tumor induced bone remodeling and observed osteolytic lesions as well as extra-periosteal aberrant bone formation in the tumor bearing femur, similar to clinical findings in patients with bone metastatic prostate cancer. Within the tumor bearing femur, we observed reorganization of blood vessels, macrophage and nerve fibers within the intramedullary space and periosteum adjacent to tumor cells. Tumor bearing mice displayed significant increases in the injury marker ATF3 and upregulation of the neuropeptides SP and CGRP in the ipsilateral DRG as well as increased measures of central sensitization and glial activation in the ipsilateral spinal cord. This immunocompetent mouse model will be useful when combined with cell type selective transgenic mice to examine tumor, immune cell and sensory neuron interactions in the bone microenvironment and their role in pain and disease progression associated with bone metastatic prostate cancer.

Effects of a digital diabetes prevention program on cardiovascular risk among individuals with prediabetes.

OBJECTIVE: To examine changes in cardiovascular disease (CVD) risk outcomes of overweight/obese adults with prediabetes. METHODS: Using data from a randomized control trial of digital diabetes prevention program (d-DPP) with 599 participants. We applied the atherosclerotic CVD (ASCVD) risk calculator to predict 10-year CVD risk for d-DPP and small education (comparison) groups. Between-group risk changes at 4 and 12 months were compared using a repeated measures linear mixed-effect model. We examined within-group differences in proportion of participants over time for specific CVD risk factors using generalized estimating equations. RESULTS: We found no differences between baseline 10-year ASCVD risk. Relative to the comparison group, the d-DPP group experienced greater reductions in predicted 10-year ASCVD risk at each follow-up visit and a significant group difference at 4 months (-0.96%; 95% confidence interval: -1.58%, -0.34%) (but not at 12 months). Additionally, we observed that the d-DPP group experienced a decreased proportion of individuals with hyperlipidemia (18% and 16% from baseline to 4 and 12 months), high-risk total cholesterol (8% from baseline to 12 months), and being insufficiently active (26% and 22% from baseline to 4 and 12 months at follow-up time points. CONCLUSIONS: Our findings suggest that a digitally adapted DPP may promote the prevention of cardiometabolic disease among overweight/obese individuals with prediabetes. However, given the lack of maintenance of effect on ASCVD risk at 12 months, there may also be a need for additional interventions to sustain the effect detected at 4 months.

Pilot study of implementing the Shared Healthcare Actions & Reflections Electronic systems in Survivorship (SHARE-S) program in coordination with clinical care.

INTRODUCTION: Initial cancer survivorship care planning efforts focused on information sharing demonstrated limited impact on patient health outcomes. We designed the Shared Healthcare Actions & Reflections Electronic Systems in survivorship (SHARE-S) program to enhance survivorship guideline implementation by transitioning some effort from clinicians to technology and patients through supporting health self-management (e.g., healthy lifestyles). METHODS: We conducted a single-group hybrid implementation-effectiveness pilot study. SHARE-S incorporated three strategies: (1) e-referral from the clinical team for patient engagement, (2) three health self-management coach calls, and (3) text messages to enhance coaching. Our primary implementation measure was the proportion of patients e-referred who enrolled (target >30%). Secondary implementation measures assessed patient engagement. We also measured effectiveness by describing changes in patient health outcomes. RESULTS: Of the 118 cancer survivor patients e-referred, 40 engaged in SHARE-S (proportion enrolled = 34%). Participants had a mean age of 57.4 years (SD = 15.7), 73% were female, 23% were Black/African American, and 5 (12.5%) were from a rural location. Patient-level adherence to coach calls was >90%. Changes from baseline to follow-up showed at least a small effect (Cohen's d = 0.2) for improvements in: mindful attention, alcohol use, physical activity, fruit and vegetable intake, days of mindfulness practice, depressive symptoms, ability to participate in social roles and activities, cancer-specific quality of life, benefits of having cancer, and positive feelings. CONCLUSION: The SHARE-S program successfully engaged cancer survivor patients. Once enrolled, patients showed promising improvements in health outcomes. Supporting patient self-management is an important component of optimizing delivery of cancer survivorship care.
