Mechanical Venous Thrombectomy for Deep Venous Thrombosis in Cancer Patients: A Single-Center Retrospective Study.

PURPOSE: Venous thromboembolism (VTE) is a major contributor to the mortality of cancer patients. Mechanical thrombectomy (MT) is an endovascular technique that physically removes a thrombus without thrombolytics. The purpose of this study was to evaluate safety, efficacy, and clinical outcomes following MT for lower extremity DVT in cancer patients. METHODS: This single-center, retrospective study evaluated outcomes following MT of lower extremity DVT in cancer patients from November 2019 to May 2023. The primary outcome measure was clinical success, defined as a decrease in Villalta score by at least 2 points following the intervention. Secondary outcomes included repeat intervention-free survival and overall survival. Technical success was defined as restoring venous flow with mild (< 10%) or no residual filling defect. RESULTS: In total, 90 patients and 113 procedures were included. Technical and clinical success was achieved in 81% and 87% of procedures performed. Repeat intervention-free survival at 1 month, 3 months, and 6 months post-procedure was 92%, 82%, and 77%, respectively. The complication rate was 2.7%. Pathologic analysis of the extracted thrombus revealed tumor thrombus in 18.4% (18/98) samples. Overall survival for the study cohort was 87% at 1 month, 74% at 3 months, and 62% at 6 months. Patients who were found to have tumor thrombi were noted to have a decreased overall survival compared to patients with non-tumor thrombi (P = 0.012). CONCLUSION: MT is safe and efficacious in reducing cancer patients' VTE-related symptoms. The high rate of tumor thrombus in thrombectomy specimens suggests this phenomenon is more common than suspected.

Bimekizumab for the treatment of psoriasis.

Psoriasis is a chronic inflammatory skin condition characterized by Th17 T cell-mediated inflammation. An emerging treatment option for psoriasis is bimekizumab, a humanized monoclonal antibody targeting cytokines IL-17A and IL-17F. Phase I trials evaluating bimekizumab reported strong safety, tolerability, and clinical efficacy with most common treatment emergent adverse events being mild to moderate in nature. Phase II trials evaluated dosing intervals, revealing that higher dosages or more frequent administration of bimekizumab resulted in minimal increases in adverse events. Phase III trials and open label extension studies demonstrated a rapid, sustained clinical response when compared with placebo and active comparators. Bimekizumab shows strong efficacy in the treatment of psoriasis and has potential in the treatment of other Th17-mediated pathologies.

Psoriasis is a chronic skin problem caused by the body's immune system. Bimekizumab, a new treatment, targets certain parts of the immune system involved in psoriasis. Studies testing bimekizumab in different phases showed it is safe and effective in treating psoriasis. Many patients taking bimekizumab had good results with mild side effects, and higher doses were well tolerated. When patients taking bimekizumab were followed for multiple years, the longitudinal study showed it worked well and continued to work. Bimekizumab works well for psoriasis but might help with similar immune-related conditions.

3D Back Contour Metrics in Predicting Idiopathic Scoliosis Progression: Retrospective Cohort Analysis, Case Series Report and Proof of Concept.

Adolescent Idiopathic Scoliosis is a 3D spinal deformity commonly characterized by serial radiographs. Patients with AIS may have increased average radiation exposure compared to unaffected patients and thus may be implicated with a modest increase in cancer risk. To minimize lifetime radiation exposure, alternative imaging modalities such as surface topography are being explored. Surface topography (ST) uses a camera to map anatomic landmarks of the spine and contours of the back to create software-generated spine models. ST has previously shown good correlation to radiographic measures. In this study, we sought to use ST in the creation of a risk stratification model. A total of 38 patients met the inclusion criteria for curve progression prediction. Scoliotic curves were classified as progressing, stabilized, or improving, and a predictive model was created using the proportional odds logistic modeling. The results showed that surface topography was able to moderately appraise scoliosis curvatures when compared to radiographs. The predictive model, using demographic and surface topography measurements, was able to account for 86.9% of the variability in the future Cobb angle. Additionally, attempts at classification of curve progression, stabilization, or improvement were accurately predicted 27/38 times, 71%. These results provide a basis for the creation of a clinical tool in the tracking and prediction of scoliosis progression in order to reduce the number of X-rays required.

Correlation of transverse rotation of the spine using surface topography and 3D reconstructive radiography in children with idiopathic scoliosis.

PURPOSE: The relationship between axial surface rotation (ASR) measured by surface topography (ST) and axial vertebral rotation (AVR) measured by radiography in the transverse plane is not well defined. This study aimed to: (1) quantify ASR and AVR patterns and their magnitudes from T1 to L5; (2) determine the correlation or agreement between the ASR and AVR; and (3) investigate the relationship between axial rotation differences (ASR-AVR) and major Cobb angle. METHODS: This is a retrospective study evaluating patients (age 8-18) with IS or spinal asymmetry with both radiographic and ST measurements. Demographics, descriptive analysis, and correlations and agreements between ASR and AVR were evaluated. A piecewise linear regression model was further created to relate rotational differences to Cobb angle. RESULTS: Fifty-two subjects met inclusion criteria. Mean age was 14.1 ± 1.7 and 39 (75%) were female. Looking at patterns, AVR had maximal rotation at T8, while ASR had maximal rotation at T11 (r = 0.35, P = .006). Cobb angle was 24.1° ± 13.3° with AVR of - 1° ± 4.6° and scoliotic angle was 20.9° ± 11.5° with ASR of - 2.3° ± 6.6°. (ASR-AVR) vs Cobb angle was found to be very weakly correlated with a curve of less than 38.8° (r = 0.15, P = .001). CONCLUSION: Our preliminary findings support that ASR measured by ST has a weak correlation with estimation of AVR by 3D radiographic reconstruction. This correlation may further help us to understand the application of transverse rotation in some clinical scenarios such as specific casting manipulation, padding mechanism in brace, and surgical correction of rib deformity.

Pharmacogenomic testing for CYP2C19 and CYP2D6 in cyclic vomiting syndrome.

BACKGROUND: Amitriptyline (AT) is recommended as first-line prophylactic therapy in patients with cyclic vomiting syndrome (CVS). However, significant side effects limit its use and dosing is based on trial and error. Though the Clinical Pharmacogenetic Implementation Consortium (CPIC) Guidelines recommend dosing for AT based on CY2D6 and CYP2C19 genotype profile, this is not followed in clinical practice. METHODS: This pilot study determined CYP2C19 and CYP2D6 genotypes and ascertained its association with adverse drug reactions (ADRs), clinical response, and serum concentration of AT and nortriptyline in a well-characterized cohort of adults with CVS. KEY RESULTS: Of 46 subjects with CVS, age 33 ± 12 years, 61% female, 85% Caucasian, a third (33%) had normal CYP2C19 metabolizer status, while 4% were poor, and 43% were ultrarapid metabolizers. Most (61%) had normal CYP2D6 genotype while 9% were poor and 2% were ultra-rapid metabolizers. There was no statistically significant association between genotype and ADRs, clinical response or serum drug concentration. There was a trend towards significance between genotype and clinical response, with 64% of responders having normal CYP2D6 metabolism versus 36% of nonresponders (p = 0.06). ADRs were encountered in 46% of patients with 28% discontinuing the medication as a result. CONCLUSIONS AND INFERENCES: A subset of patients with CVS have dysfunctional alleles of CYP2C19 and CYP2D6. Larger prospective studies to evaluate the clinical impact of pharmacogenomic testing in CVS are needed. This has the potential to optimize clinical management, predict ADRs and allow for personalized therapy.

Threat of shock increases distractor susceptibility during the short-term maintenance of visual information.

BACKGROUND: Work on anxiety related attention control deficits suggests that elevated arousal impacts the ability to filter out distractors. To test this, we designed a task to look at distractor suppression during periods of threat. We administered trials of a visual short-term memory (VSTM) task, during periods of unpredictable threat, and hypothesized that threat would impair performance during trials where subjects were required to filter out large numbers of distractors. METHOD: Experiment 1 involved fifteen healthy participants who completed one study visit. They performed four runs of a VSTM task comprising 32 trials each. Participants were presented with an arrow indicating left or right, followed by an array of squares. They were instructed to remember the target side and disregard the distractors on the off-target side. A subsequent target square was shown, and participants indicated whether it matched one of the previously presented target squares. The trial conditions included 50% matches and 50% mismatches, with an equal distribution of left and right targets. The number of target and distractor squares varied systematically, with high (4 squares) and low (2 squares) target and distractor conditions. Trials alternated between periods of safety and threat, with startle responses recorded using electromyography (EMG) following white noise presentations. Experiment 2 involved twenty-seven healthy participants who completed the same VSTM task inside an MRI scanner during a single study visit. The procedure mirrored that of Experiment 1, except for the absence of white noise presentations. RESULTS: For Experiment 1, subjects showed significantly larger startle responses during threat compared to safe period, supporting the validity of the threat manipulation. However, results suggested that the white noise probes interfered with performance. For Experiment 2, we found that both accuracy was affected by threat, such that distractor load negatively impacted accuracy only in the threat condition. CONCLUSION: Overall, these findings suggest that threat affects distractor susceptibility during the short-term maintenance of visual information. The presence of threat makes it more difficult to filter out distracting information. We believe that this is related to hyperarousal of parietal cortex, which has been observed during unpredictable threat.

Aligned Collagen Sponges with Tunable Pore Size for Skeletal Muscle Tissue Regeneration.

Volumetric muscle loss (VML) is a traumatic injury where at least 20% of the mass of a skeletal muscle has been destroyed and functionality is lost. The standard treatment for VML, autologous tissue transfer, is limited as approximately 1 in 10 grafts fail because of necrosis or infection. Tissue engineering strategies seek to develop scaffolds that can regenerate injured muscles and restore functionality. Many of these scaffolds, however, are limited in their ability to restore muscle functionality because of an inability to promote the alignment of regenerating myofibers. For aligned myofibers to form on a scaffold, myoblasts infiltrate the scaffold and receive topographical cues to direct targeted myofiber growth. We seek to determine the optimal pore size for myoblast infiltration and differentiation. We developed a method of tuning the pore size within collagen scaffolds while inducing longitudinal alignment of these pores. Significantly different pore sizes were generated by adjusting the freezing rate of the scaffolds. Scaffolds frozen at -20 °C contained the largest pores. These scaffolds promoted the greatest level of cell infiltration and orientation in the direction of pore alignment. Further research will be conducted to induce higher levels of myofiber formation, to ultimately create an off-the-shelf treatment for VML injuries.

Interleaved TMS/fMRI shows that threat decreases dlPFC-mediated top-down regulation of emotion processing.

Background: The right dorsolateral prefrontal cortex (dlPFC) has been indicated to be a key region in the cognitive regulation of emotion by many previous neuromodulation and neuroimaging studies. However, there is little direct causal evidence supporting this top-down regulation hypothesis. Furthermore, it is unclear whether contextual threat impacts this top-down regulation. By combining TMS/fMRI, this study aimed to uncover the impact of unpredictable threat on TMS-evoked BOLD response in dlPFC-regulated emotional networks. Based on the previous findings linking the dlPFC to the downregulation of emotional network activity, we hypothesized TMS pulses would deactivate activity in anxiety expression regions, and that threat would reduce this top-down regulation. Methods: 44 healthy controls (no current or history of psychiatric disorders) were recruited to take part in a broader study. Subjects completed the neutral, predictable, and unpredictable (NPU) threat task while receiving TMS pulses to either the right dlPFC or a control region. dlPFC targeting was based on data from a separate targeting session, where subjects completed the Sternberg working memory (WM) task inside the MRI scanner. Results: When compared to safe conditions, subjects reported significantly higher levels of anxiety under threat conditions. Additionally, TMS-evoked responses in the left insula (LI), right sensory/motor cortex (RSM), and a region encompassing the bilateral SMA regions (BSMA) differed significantly between safe and threat conditions. There was a significant TMS-evoked deactivation in safe periods that was significantly attenuated in threat periods across all 3 regions. Conclusions: These findings suggest that threat decreases dlPFC-regulated emotional processing by attenuating the top-down control of emotion, like the left insula. Critically, these findings provide support for the use of right dlPFC stimulation as a potential intervention in anxiety disorders.

The maintenance of complex visual scenes in working memory may require activation of working memory manipulation circuits in the dlPFC.

Past research has shown that the bilateral dorsolateral prefrontal cortices (dlPFC) are implicated in both emotional processing as well as cognitive processing, 1,2,3 in addition to working memory 4, 5 . Exactly how these disparate processes interact with one another within the dlPFC is less understood. To explore this, researchers designed an experiment that looked at working memory performance during fMRI under both emotional and non-emotional task conditions. Participants were asked to complete three tasks (letters, neutral images, emotional images) of the Sternberg Sorting Task under one of two trial conditions (sort or maintain). Regions of interest consisted of the left and right dlPFC as defined by brain masks based on NeuroSynth 6 . Results showed a significant main effect of the 'sort' condition on reaction speed for all three trial types, as well as a main effect of task type (letters) on accuracy. In addition, a significant interaction was found between trial type (sort) and task type (letters), but not for either of the picture tasks. These results reveal a discrepancy between BOLD signal and behavioral data, with no significant difference in BOLD activity during image trials being displayed, despite longer response times for every condition. While these results show that the dlPFC is clearly implicated in non-emotional cognitive processing, more research is needed to explain the lack of BOLD activation seen here for similar emotionally valanced tasks, possibly indicating involvement of other brain networks.

Aging and Cerebral Glucose Metabolism: 18F-FDG-PET/CT Reveals Distinct Global and Regional Metabolic Changes in Healthy Patients.

Alterations in cerebral glucose metabolism can be indicative of both normal and pathological aging processes. In this retrospective study, we evaluated global and regional neurological glucose metabolism in 73 healthy individuals (mean age: 35.8 ± 13.1 years; 82.5% female) using 18F-Fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). This population exhibited a low prevalence of comorbidities associated with cerebrovascular risk factors. We utilized 18F-FDG-PET/CT imaging and quantitative regional analysis to assess cerebral glucose metabolism. A statistically significant negative correlation was found between age and the global standardized uptake value mean (SUVmean) of FDG uptake (p = 0.000795), indicating a decrease in whole-brain glucose metabolism with aging. Furthermore, region-specific analysis identified significant correlations in four cerebral regions, with positive correlations in the basis pontis, cerebellar hemisphere, and cerebellum and a negative correlation in the lateral orbital gyrus. These results were further confirmed via linear regression analysis. Our findings reveal a nuanced understanding of how aging affects glucose metabolism in the brain, providing insight into normal neurology. The study underscores the utility of 18F-FDG-PET/CT as a sensitive tool in monitoring these metabolic changes, highlighting its potential for the early detection of neurological diseases and disorders related to aging.

Empyema Presentation Secondary to Streptococcus constellatus.

A 60-year-old male presented to our institution for abdominal pain and was later admitted to the intensive care unit for shock, acute hypoxemic respiratory failure, and acute kidney injury. He was subsequently found to have a large left-sided pleural effusion with empyema secondary to Streptococcus constellatus. With the emerging threat and growing prevalence of Streptococcus anginosus group pathogens, there is now greater clinical importance in identifying viridans streptococci at the species level. While immunosuppressed individuals are at greater risk of opportunistic pathogens, this case presentation demonstrated that Streptococcus constellatus can remain a serious community-acquired pathogen for the non-immunosuppressed. Continued interprofessional team care management and a greater look into the reasons for greater Streptococcus anginosus pathogenicity may be indicated.

Real-World Use of Electronic Patient-Reported Outcome (ePRO) Tools Integrated in the Electronic Medical Record During Radiation Therapy for Head and Neck Cancer: Feasibility Study.

Purpose Use of electronic patient-reported outcome (ePRO) tools in routine oncology practice can be challenging despite evidence showing they can improve survival, improve patient and practitioner satisfaction, and reduce medical resource utilization. Head and neck cancer (HNC) patients receiving radiation therapy (RT) may be a group that would particularly benefit from interventions focused on early symptom management. Methods Patients undergoing definitive RT for HNC were enrolled in a feasibility study and received ePRO surveys integrated within the electronic medical record (EMR) on a weekly basis during RT. After completion of each ePRO survey, a radiation oncology registered nurse documented the findings and subsequent interventions within the EMR. Results Thirty-four patients with HNC who received curative RT at a single center were enrolled. The total number of surveys completed was 194 with a median of 7 surveys per patient (range 1-8). There was a total of 887 individual abnormal findings reported on the ePROs, and the authors found that all 887 had a corresponding documented intervention. Post-treatment practitioner questionnaires highlighted that ePROs were felt to be helpful for the care team in providing care to HNC patients. Conclusion For patients with HNC receiving RT, ePROs can be effectively utilized to address patient symptoms within an integrated health care system. Creating an infrastructure for the use of ePROs integrated within the EMR in routine care requires an approach that accounts for local workflows and buy-in from patients and the entire care team.

A Case Report of a LVAD Driveline Infection Diagnosed by Point-of-care Ultrasound.

INTRODUCTION: As the prevalence of patients with left ventricular assist devices (LVAD) presenting to the emergency department (ED) increases, clinicians must be aware of LVAD-associated infections. CASE REPORT: A well-appearing, 41-year-old male with history of heart failure status post prior-LVAD placement presented to the ED for swelling of his chest. What appeared initially as a superficial infection was further assessed with point-of-care ultrasound and found to represent a chest wall abscess involving the driveline, ultimately resulting in sternal osteomyelitis and bacteremia. CONCLUSION: Point-of-care ultrasound should be considered an important tool in the initial assessment of potential LVAD-associated infection.

Barriers to Telemedicine Use: Qualitative Analysis of Provider Perspectives During the COVID-19 Pandemic.

BACKGROUND: Though telemedicine is a promising approach for removing barriers to care and improving access for patients, telemedicine use for many medical specialties has decreased from its peak during the acute COVID-19 public health crisis. Understanding the barriers and facilitators to the maintenance of web-based visits-one key component of telemedicine-is critical for ensuring the continuous availability of this service for patients. OBJECTIVE: The purpose of this study is to describe medical providers' perceived barriers and facilitators to the continued use of web-based visits to inform quality improvement efforts and promote sustainability. METHODS: We performed a qualitative content analysis of free-text responses from a survey of medical providers administered from February 5-14, 2021, at a large, midwestern academic institution, including all providers from medical professions that offered telemedicine (eg, physicians, residents or fellows, nurse practitioners, physicians assistants, or nurses) who completed at least 1 web-based visit from March 20, 2020, to February 14, 2021. The primary outcome was the experience of providing web-based visits, including barriers and facilitators to continued usage of web-based visits. Survey questions included 3 major domains: quality of care, technology, and satisfaction. Responses were coded using qualitative content analysis and further analyzed through a matrix analysis to understand the providers' perspectives and elucidate key barriers and facilitators of web-based visit usage. RESULTS: Of 2692 eligible providers, 1040 (38.6%) completed the survey, of whom 702 were providers from medical professions that offered telemedicine. These providers spanned 7 health care professions and 47 clinical departments. The most common professions represented were physicians (486/702, 46.7%), residents or fellows (85/702, 8.2%), and nurse practitioners (81/702, 7.8%), while the most common clinical departments were internal medicine (69/702, 6.6%), psychiatry (69/702, 6.6%), and physical medicine and rehabilitation (67/702, 6.4%). The following 4 overarching categories of provider experience with web-based visits emerged: quality of care, patient rapport, visit flow, and equity. Though many providers saw web-based visits as a tool for improving care access, quality, and equity, others shared how appropriate selection of web-based visits, support (eg, patient training, home devices, and broadband access), and institutional and nationwide optimization (eg, relaxation of licensing requirements across state borders and reimbursement for phone-only modalities) were needed to sustain web-based visits. CONCLUSIONS: Our findings demonstrate key barriers to the maintenance of telemedicine services following the acute public health crisis. These findings can help prioritize the most impactful methods of sustaining and expanding telemedicine availability for patients who prefer this method of care delivery.

Locally Advanced Lung Cancer.

Consolidation immunotherapy after concurrent chemoradiation has improved five-year survival rates in unresectable, locally advanced lung cancer, but disease progression and treatment personalization remain challenges. New treatment approaches with concurrent immunotherapy and consolidative novel agents are being investigated and show promising efficacy data, but at the risk of additive toxicity. Patients with PD-L1 negative tumors, oncogenic driver mutations, intolerable toxicity, or limited performance status continue to require innovative therapies. This review summarizes historical data that galvanized new research efforts, as well as ongoing clinical trials that address the challenges of current therapeutic approaches for unresectable, locally advanced lung cancer.

Clinical characteristics and long-term outcomes in patients with cyclic vomiting syndrome: A 15-year experience at a tertiary referral center.

BACKGROUND: Cyclic vomiting syndrome (CVS) is a disorder of gut-brain interaction (DGBI) characterized by recurrent episodes of nausea and vomiting. Most children outgrow their CVS symptoms and develop migraine headaches, but there are limited data in adults. We thus sought to determine the natural history of CVS in adults. METHODS: We conducted a retrospective analysis of patients at a specialized tertiary care clinic. Frequency of CVS episodes, emergency department (ED) visits, and hospitalizations were recorded at the index visit and at follow-up. KEY RESULTS: Of 455 CVS patients with complete data, mean age was 33 ± 13 years, 294 (65%) were female, and 392 (86%) were Caucasian. Mean duration of follow-up was 47.4 ± 37.2 months. There was a significant reduction in frequency of CVS episodes/year (18 to 6.8), ED visits (6.1 to 2), and hospitalizations (2.3 to 0.7) (all p-values < 0.001) but only 88 (19%) of patients had complete resolution of episodes at follow-up. On multivariable regression analysis, non-white race [0.33 (0.11-0.98) p = 0.01], comorbidity count [0.77 (0.62-0.95) p = 0.01], cannabis use [0.36 (0.2-0.65) p = 0.0007], and aprepitant use [0.2 (0.08-0.005) p < 0.001] were associated with a reduced odds of complete resolution of CVS episodes. Of note, 19 patients (4%) died. CONCLUSIONS AND INFERENCES: While most adults with CVS improved with specialized care, in contrast to children, only a small subset (~1 in 5) had complete resolution of symptoms. Reasons for the effects of race, cannabis use, and comorbidity burden on outcomes in CVS are unclear and warrant further investigation.

Cxbladder Monitor testing to reduce cystoscopy frequency in patients with bladder cancer.

PURPOSE: Bladder cancer surveillance is associated with high costs and patient burden. CxMonitor (CxM), a home urine test, allows patients to skip their scheduled surveillance cystoscopy if CxM-negative indicating a low probability of cancer presence. We present outcomes from a prospective multi-institutional study of CxM to reduce surveillance frequency during the coronavirus pandemic. MATERIALS AND METHODS: Eligible patients due for cystoscopy from March-June 2020 were offered CxM and skipped their scheduled cystoscopy if CxM-negative. CxM-positive patients came for immediate cystoscopy. The primary outcome was safety of CxM-based management, assessed by frequency of skipped cystoscopies and detection of cancer at immediate or next cystoscopy. Patients were surveyed on satisfaction and costs. RESULTS: During the study period, 92 patients received CxM and did not differ in demographics nor history of smoking/radiation between sites. 9 of 24 (37.5%) CxM-positive patients had 1 T0, 2 Ta, 2 Tis, 2 T2, and 1 Upper tract urothelial carcinoma (UTUC) on immediate cystoscopy and subsequent evaluation. 66 CxM-negative patients skipped cystoscopy, and none had findings on follow-up cystoscopy requiring biopsy. Six of these patients did not attend follow-up, 4 elected to undergo additional CxM instead of cystoscopy, 2 stopped surveillance, and 2 died of unrelated causes. CxM-negative and positive patients did not differ in demographics, cancer history, initial tumor grade/stage, AUA risk group, or number of prior recurrences. Median satisfaction (5/5, IQR 4-5) and costs (26/33, 78.8% no out-of-pocket costs) were favorable. CONCLUSIONS: CxM safely reduces frequency of surveillance cystoscopy in real-world settings and appears acceptable to patients as an at-home test.

Efficacy of aprepitant as a prophylactic medication in adults with cyclic vomiting syndrome.

BACKGROUND: Aprepitant is a neurokinin-1 receptor antagonist, and recent guidelines by the American Neurogastoenterology and Motility Society recommend its use as prophylaxis in moderate-to severe cyclic vomiting syndrome (CVS). Data are limited to small studies in children. We aimed to determine its efficacy in adults with CVS. METHODS: A retrospective review of CVS patients diagnosed using Rome criteria at a tertiary referral center was conducted. Drug response was defined as >50% reduction in symptoms and/or healthcare utilization. An intent-to-treat (ITT) analysis was conducted. KEY RESULTS: Of 96 patients prescribed aprepitant, 26 (27%) were unable to start due to cost/lack of insurance coverage. Of 70 receiving therapy, mean age was 33 ± 11 years; 51 (73%) were female and 56 (80%) Caucasian. The majority (93%) were refractory to other prophylactic medications. Aprepitant was taken thrice weekly in 51 (73%), daily in 16 (23%) and a few times a month in 3 (4%) due to cost. Fifty (71.4%) had a global symptom response to aprepitant. There was significant reduction in the number of CVS episodes (14.5 ± 11.7 to 6.2 ± 8.0, p < 0.0001), emergency department visits (4.2 ± 7.7 to 1.8 ± 3.4, p = 0.006), and hospital admissions (1.6 ± 3.9 to 0.8 ± 2.1, p = 0.02) in patients treated with aprepitant. Seven (10%) discontinued the drug due to minor side effects. CONCLUSIONS AND INFERENCES: Aprepitant is a safe and effective prophylactic medication in adults with refractory CVS. Adequate insurance coverage is a major barrier preventing its use.

Evaluation of Social Determinants of Health and Prostate Cancer Outcomes Among Black and White Patients: A Systematic Review and Meta-analysis.

Importance: As the field of medicine strives for equity in care, research showing the association of social determinants of health (SDOH) with poorer health care outcomes is needed to better inform quality improvement strategies. Objective: To evaluate the association of SDOH with prostate cancer-specific mortality (PCSM) and overall survival (OS) among Black and White patients with prostate cancer. Data Sources: A MEDLINE search was performed of prostate cancer comparative effectiveness research from January 1, 1960, to June 5, 2020. Study Selection: Two authors independently selected studies conducted among patients within the United States and performed comparative outcome analysis between Black and White patients. Studies were required to report time-to-event outcomes. A total of 251 studies were identified for review. Data Extraction and Synthesis: Three authors independently screened and extracted data. End point meta-analyses were performed using both fixed-effects and random-effects models. The Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guideline was followed, and 2 authors independently reviewed all steps. All conflicts were resolved by consensus. Main Outcomes and Measures: The primary outcome was PCSM, and the secondary outcome was OS. With the US Department of Health and Human Services Healthy People 2030 initiative, an SDOH scoring system was incorporated to evaluate the association of SDOH with the predefined end points. The covariables included in the scoring system were age, comorbidities, insurance status, income status, extent of disease, geography, standardized treatment, and equitable and harmonized insurance benefits. The scoring system was discretized into 3 categories: high (≥10 points), intermediate (5-9 points), and low (<5 points). Results: The 47 studies identified comprised 1 019 908 patients (176 028 Black men and 843 880 White men; median age, 66.4 years [IQR, 64.8-69.0 years]). The median follow-up was 66.0 months (IQR, 41.5-91.4 months). Pooled estimates found no statistically significant difference in PCSM for Black patients compared with White patients (hazard ratio [HR], 1.08 [95% CI, 0.99-1.19]; P = .08); results were similar for OS (HR, 1.01 [95% CI, 0.95-1.07]; P = .68). There was a significant race-SDOH interaction for both PCSM (regression coefficient, -0.041 [95% CI, -0.059 to 0.023]; P < .001) and OS (meta-regression coefficient, -0.017 [95% CI, -0.033 to -0.002]; P = .03). In studies with minimal accounting for SDOH (<5-point score), Black patients had significantly higher PCSM compared with White patients (HR, 1.29; 95% CI, 1.17-1.41; P < .001). In studies with greater accounting for SDOH variables (≥10-point score), PCSM was significantly lower among Black patients compared with White patients (HR, 0.86; 95% CI, 0.77-0.96; P = .02). Conclusions and Relevance: The findings of this meta-analysis suggest that there is a significant interaction between race and SDOH with respect to PCSM and OS among men with prostate cancer. Incorporating SDOH variables into data collection and analyses are vital to developing strategies for achieving equity.
