Nicotinic Receptor Alpha-5 Subunit Gene Polymorphism is Associated with Heavy Smoking Under a Range of Nicotine Dosing Conditions.

INTRODUCTION: This study aimed to assess the role of the rs16969968 variant of nicotinic receptor alpha-5 subunit in regulating smoking behavior and nicotine intake in response to nicotine manipulations among dependent smokers in a naturalistic environment. METHODS: Sixty-nine adults (19 females) smoking 10 or more cigarettes per day were asked to complete four 2-week study phases during which they smoked exclusively one of two types of Spectrum nicotine research cigarettes (FTC nicotine yield 0.8 and 1.6 mg, respectively), their usual brand of cigarettes, or their usual brand of cigarettes while wearing a 21-mg nicotine patch. Measurements included rs16969968 genotype, number of cigarettes per day, smoking topography, and plasma cotinine. RESULTS: Compared to controls (G/G carriers), A allele carriers reported smoking 4 to 5 more cigarettes per day across all conditions (all ps < .05). Mean total smoke volume per day and cotinine were greater in A allele carriers than in controls (ps = 0.05, 0.046, respectively). No significant genotype differences were found in smoking compensation indices for the switch from Medium to High nicotine yield cigarettes. Nicotine patch-induced reductions in cigarettes smoked per day and total smoke volume per day showed significant interactions between genotype and pre-patch levels, heavier smokers showing greater effects of genotype (p = .052 and p =.006, respectively). CONCLUSIONS: Results suggest that the rs16969968 variants regulate heaviness of smoking primarily by their impact on daily numbers of cigarettes smoked, but no genotype differences were found in smoking compensation after switching from Medium to High nicotine cigarettes. IMPLICATIONS: The differences in daily cigarette consumption between rs16969968 risk-allele carriers and controls are shown to be consistent regardless of manipulations of cigarette nicotine content and transdermal nicotine supplementation and markedly greater among dependent smokers than those observed in the general smoker populations. G/G allele carriers, relative to A allele carriers, appeared to be more sensitive to the nicotine patch manipulation, reducing their smoking to a greater extent. These findings support continued efforts in the development of personalized intervention strategies to reduce the rs16969968-conveyed genetic propensity for heavy smoking.

Single-cell NAD(H) levels predict clonal lymphocyte expansion dynamics.

Adaptive immunity requires the expansion of high-affinity lymphocytes from a heterogeneous pool. Whereas current models explain this through signal transduction, we hypothesized that antigen affinity tunes discrete metabolic pathways to license clonal lymphocyte dynamics. Here, we identify nicotinamide adenine dinucleotide (NAD) biosynthesis as a biochemical hub for the T cell receptor affinity-dependent metabolome. Through this central anabolic role, we found that NAD biosynthesis governs a quiescence exit checkpoint, thereby pacing proliferation. Normalizing cellular NAD(H) likewise normalizes proliferation across affinities, and enhancing NAD biosynthesis permits the expansion of lower affinity clones. Furthermore, single-cell differences in NAD(H) could predict division potential for both T and B cells, before the first division, unmixing proliferative heterogeneity. We believe that this supports a broader paradigm in which complex signaling networks converge on metabolic pathways to control single-cell behavior.

Managing Disease-Modifying Antirheumatic Drugs (DMARDs) for Patients Undergoing Elective Spine Surgery: A Pilot Survey.

Introduction: Patients affected by autoimmune pathologies such as rheumatoid arthritis require surgery for various reasons. However, the systemic inflammatory nature of these disease processes often necessitates therapy with disease-modifying antirheumatic drugs (DMARDs). Alteration of these agents in the perioperative period for surgery requires a careful risk-benefit analysis to limit disease flares, infection rates, and secondary revisions. We therefore queried North and South American practices for perioperative management of DMARDs in patients undergoing elective spine surgery. Methods: An institutional review board-approved pilot survey was disseminated to spine surgeons regarding how they managed DMARDs before, during, and after spine surgery. Results: A total of 47 spine surgeons responded to the survey, 37 of whom were neurosurgeons (78.7%) and 10 orthopedic surgeons (21.3%). Of the respondents, 80.9% were from North America, 72.3% were board-certified, 51.1% practiced in academic institutions, and 66.0% performed 50-150 spine surgeries per year. Most respondents consulted a rheumatologist before continuing or withholding a DMARD in the perioperative period (70.2%). As such, a majority of the spine surgeons in this survey withheld DMARDs at an average of 13.8 days before and 19.6 days after spine surgery. Of the spine surgeons who withheld DMARDs before and after spine surgery, the responses were variable with a trend toward no increased risk of postoperative complications. Conclusions: Based on the results of this pilot survey, we found a consensus among spine surgeons to withhold DMARDs before and after elective spine surgery.

Deficiencies in cluster-2 ALA lipid flippases result in salicylic acid-dependent growth reductions.

P4 ATPases (i.e., lipid flippases) are eukaryotic enzymes that transport lipids across membrane bilayers. In plants, P4 ATPases are named Aminophospholipid ATPases (ALAs) and are organized into five phylogenetic clusters. Here we generated an Arabidopsis mutant lacking all five cluster-2 ALAs (ala8/9/10/11/12), which is the most highly expressed ALA subgroup in vegetative tissues. Plants harboring the quintuple knockout (KO) show rosettes that are 2.2-fold smaller and display chlorotic lesions. A similar but less severe phenotype was observed in an ala10/11 double KO. The growth and lesion phenotypes of ala8/9/10/11/12 mutants were reversed by expressing a NahG transgene, which encodes an enzyme that degrades salicylic acid (SA). A role for SA in promoting the lesion phenotype was further supported by quantitative PCR assays showing increased mRNA abundance for an SA-biosynthesis gene ISOCHORISMATE SYNTHASE 1 (ICS1) and two SA-responsive genes PATHOGENESIS-RELATED GENE 1 (PR1) and PR2. Lesion phenotypes were also reversed by growing plants in liquid media containing either low calcium (~0.1 mM) or high nitrogen concentrations (~24 mM), which are conditions known to suppress SA-dependent autoimmunity. Yeast-based fluorescent lipid uptake assays revealed that ALA10 and ALA11 display overlapping substrate specificities, including the transport of LysoPC signaling lipids. Together, these results establish that the biochemical functions of ALA8-12 are at least partially overlapping, and that deficiencies in cluster-2 ALAs result in an SA-dependent autoimmunity phenotype that has not been observed for flippase mutants with deficiencies in other ALA clusters.

Efficacy and safety of daratumumab, pomalidomide, and dexamethasone versus daratumumab, carfilzomib, and dexamethasone in daratumumab-naïve relapsed multiple myeloma.

OBJECTIVES AND METHODS: We conducted a multicenter retrospective study to analyze the safety and efficacy of DPd versus DKd in daratumumab naïve RRMM patients treated in real-world practice. RESULTS: A total of 187 patients with RRMM were included in the analysis; 128 patients received DPd, and 59 patients received DKd. A vast majority (80%) of patients had lenalidomide refractory disease and nearly 50% had bortezomib refractory disease. The overall response and complete response rates were 76% and 34% in the DPd group versus 80% and 51% in the DKd group, respectively. With a median follow up of 36 months for the entire patient population, median PFS and OS in the DPd versus DKd groups were 12, 12, 37, and 35 months, respectively. The most common grade 3+ adverse events in the DPd versus DKd groups were neutropenia (32% vs. 7%), anemia (14% vs. 10%), thrombocytopenia (13% vs. 15%), and cardiovascular events (4% vs. 15%), respectively. Both DPd and DKd appeared to be a safe and effective treatment options for RRMM. CONCLUSIONS: While there were more cytopenias associated with DPd and more cardiovascular side effects with DKd, there were no significant differences in the survival outcomes with these two regimens.

Development and Validation of a Prediction Model of Outcome After B-Cell Maturation Antigen-Directed Chimeric Antigen Receptor T-Cell Therapy in Relapsed/Refractory Multiple Myeloma.

PURPOSE: Although chimeric antigen receptor T therapy (CAR-T) cells are an established therapy for relapsed/refractory multiple myeloma (RRMM), there are no established models predicting outcome to identify patients who may benefit the most from CAR-T. PATIENTS AND METHODS: This is an international retrospective observational study including patients with RRMM infused with currently available commercial or academically produced anti-B-cell maturation antigen (BCMA) CAR-T. We describe characteristics and outcomes in Europe (n = 136) and the United States (n = 133). Independent predictors of relapse/progression built a simple prediction model (Myeloma CAR-T Relapse [MyCARe] model) in the training cohort (Europe), which was externally validated (US cohort) and tested within patient- and treatment-specific subgroups. RESULTS: The overall response rate was 87% and comparable between both cohorts, and complete responses were seen in 48% (Europe) and 49% (the United States). The median time to relapse was 5 months, and early relapse <5 months from infusion showed poor survival across cohorts, with the 12-month overall survival of 30% (Europe) and 14% (the United States). The presence of extramedullary disease or plasma cell leukemia, lenalidomide-refractoriness, high-risk cytogenetics, and increased ferritin at the time of lymphodepletion were independent predictors of early relapse or progression. Each factor received one point, forming the three-tiered MyCARe model: scores 0-1 (low risk), scores 2-3 (intermediate risk), and a score of 4 (high risk). The MyCARe model was significantly associated with distinct 5-month incidence of relapse/progression (P < .001): 7% for low-risk, 27% for intermediate-risk, and 53% for high-risk groups. The model was validated in the US cohort and maintained prognostic utility for response, survival, and outcomes across subgroups. CONCLUSION: Outcomes of patients with RRMM after CAR-T are comparable between Europe and the United States. The MyCARe model may facilitate optimal timing of CAR-T cells in patient-specific subgroups.

Daily Moderate-to-Vigorous Activity of Native Hawaiians and Pacific Islanders and Seven Asian Subgroups by Types of Activities, American Time Use Survey, 2010-2019.

The study used the American Time Use Survey data from 2010 to 2019 to compare the daily moderate-to-vigorous activity of Native Hawaiians and Pacific Islanders (NHPI) and seven Asian ethnic subgroups. Adults aged 24 years and older were included. The study analyzed activities from sports and recreation, household activities, and all activities carried out during the day. Outcomes were determined by the completion of 30 min or more of moderate-to-vigorous activity and the type of activity carried out in the day. Significant ethnic differences were observed for sports and recreation but not for household activities and not for all activities carried out during the day. Of the ethnic populations, NHPI were the least active, and Asian Indians and Chinese were the most active. A majority achieved 30 min or more of moderate-to-vigorous activity during the day from all their activities. Physical activity from household activities exceeded physical activity from sports and recreation. The most physically active group was adults over the age of 65 years, perhaps reflecting more time to exercise or greater concerns about their health. For sports and recreation, exercising with someone doubled the minutes of moderate-to-vigorous activity. The results emphasize the importance of activities performed around the household in addition to sports and recreation and the benefit of exercising with someone. Ethnic populations may be receptive to interventions that emphasize activities they are performing in their daily lives.

Impact of age, obesity, and renal impairment on outcomes after autologous stem cell transplantation for patients with newly diagnosed multiple myeloma.

INTRODUCTION: There remains a need to determine whether certain subgroups of newly diagnosed multiple myeloma (NDMM) derive the same benefit from high-dose chemotherapy-autologous stem cell transplant (HDT-ASCT). We describe our institutional experience highlighting the impact of age, obesity, and renal impairment on outcomes after HDT-ASCT for patients with NDMM in a real-world setting. METHODS: A total of 449 consecutive patients were included in this retrospective analysis. RESULTS: No difference in median progression free survival or overall survival was seen for patients with age > 65, body mass index (BMI) > 30 kg/m2, or estimated glomerular filtration rate < 60 mL/min/1.73 m2 when compared to those without these characteristics. From a safety standpoint, there were no differences in the incidence of transplant-related mortality or secondary malignancy among subgroups. CONCLUSION: For patients with NDMM undergoing HDT-ASCT, there is no difference in outcomes based on age, BMI, or renal function, and the presence of one or more of these factors should not preclude patients from HDT-ASCT.

Stability of Ocular Alignment After Teprotumumab Therapy in a Cohort of Patients With Thyroid Eye Disease and Baseline Diplopia.

BACKGROUND: Teprotumumab is a monoclonal antibody that is effective in treating patients with thyroid eye disease (TED) and has been shown to produce subjective improvements in diplopia in this group. The aims of this study were to evaluate the rate and timing of recurrence/worsening of diplopia after teprotumumab treatment in a cohort of patients with TED presenting with diplopia at baseline. METHODS: A retrospective chart review of 15 patients with diplopia secondary to TED, treated with teprotumumab, was conducted in a single-center academic institution. The primary outcome was the rate of recurrence/worsening of diplopia after completing teprotumumab. Secondary outcomes include the time to recurrence/worsening of diplopia and clinical activity scores (CAS) to correlate with changes in ocular alignment. RESULTS: Fifteen patients met the inclusion criteria for this study, and 7 of these had recurrence of diplopia (46.7%). Two patients had worsening of CAS to ≥4, 6 had worsening of CAS to 3, and the other 7 had CAS ≤2 during the follow-up period. The mean follow-up period was 20.4 months (SD 7.2) after completing teprotumumab. The mean time to diplopia recurrence/worsening was 8.8 months (range 6.7-12.2, SD 1.8). CONCLUSIONS: Patients with TED and baseline diplopia have a substantial rate of recurrence/worsening of diplopia after teprotumumab therapy, suggesting that they may not have stable ocular alignment immediately after treatment. Strabismus surgeons may need to weigh the significant risk of disease relapse when planning optimum timing for surgical correction.

Outcome differences between males and females undergoing deep brain stimulation for treatment-resistant depression: systematic review and individual patient data meta-analysis.

BACKGROUND: Treatment-resistant depression (TRD) occurs more commonly in women. Deep brain stimulation (DBS) is an emerging treatment for TRD, and its efficacy continues to be explored. However, differences in treatment outcomes between males and females have yet to be explored in formal analysis. METHODS: A PRISMA-compliant systematic review of DBS for TRD studies was conducted. Patient-level data were independently extracted by two authors. Treatment response was defined as a 50 % or greater reduction in depression score. Percent change in depression scores by gender were evaluated using random-effects analyses. RESULTS: Of 737 records, 19 studies (129 patients) met inclusion criteria. The mean reduction in depression score for females was 57.7 % (95 % CI, 64.33 %-51.13 %), whereas for males it was 35.2 % (95 % CI, 45.12 %-25.23 %) (p < 0.0001). Females were more likely to respond to DBS for TRD when compared to males (OR = 2.44, 95 % CI 1.06, 1.95). These differences varied in significance when stratified by DBS anatomical target, age, and timeframe for responder classification. LIMITATIONS: Studies included were open-label trials with small sample sizes. CONCLUSIONS: Our findings suggest that females with TRD respond at higher rates to DBS treatment than males. Further research is needed to elucidate the implications of these results, which may include connectomic sexual dimorphism, depression phenotype variations, or unrecognized symptom reporting differences. Methodological standardization of outcome scales, granular demographic data, and individual subject outcomes would allow for more robust comparisons between trials.

Efficacy and safety of idecabtagene vicleucel in patients with relapsed-refractory multiple myeloma not meeting the KarMMa-1 trial eligibility criteria: A real-world multicentre study.

Ide-cel received approval for relapsed-refractory multiple myeloma based on the results of the KarMMa-1 trial. However, patients with significant comorbidities, aggressive disease and prior B-cell maturation antigen-directed therapy (BCMA-DT) were excluded. This retrospective study evaluated real-world outcomes of patients who did not meet the KarMMa-1 eligibility criteria and were treated with standard of care (SOC) ide-cel. A total of 69 patients from three US centres who did not meet the KarMMa-1 criteria underwent ide-cel infusion. The main reasons for trial ineligibility included baseline grade 3-4 cytopenia (39%), prior BCMA-DT (26%), renal impairment (19%) and Eastern Cooperative Oncology Group performance status ≥2 (14.5%). Cytokine-release syndrome occurred in 81% vs. 84%, and immune effector cell-associated neurotoxicity syndrome occurred in 28% vs. 18% of SOC versus KarMMa-1 patients, respectively. Early infection (≤8 weeks post-infusion) and severe infection rates were 42% vs. 49% and 30% vs. 22% for the SOC versus KarMMa-1 cohorts, respectively. Grade 3-4 cytopenias for SOC versus KarMMa-1 cohorts were: neutropenia (87% vs. 89%), anaemia (51% vs. 60%) and thrombocytopenia (65% vs. 52%). Overall response rate was higher for the SOC cohort (93% vs. 73%), as was the complete response or better rate (48% vs. 33%). However, median progression-free survival and overall survival were comparable between the two groups. Our findings support broadening the inclusion criteria of future trials evaluating ide-cel.

Early versus standard management of chimeric antigen receptor therapy toxicities and management's impact on safety and efficacy.

BACKGROUND: Cytokine release syndrome (CRS) and immune effector cell-associated neurologic syndrome (ICANS) are well-documented toxicities of CAR T-cell therapy. To mitigate excessive toxicity, our center has formulated treatment protocols (early vs. standard) for timely management of CRS and ICANS with tocilizumab and/or corticosteroids. METHODS: This retrospective, single-center analysis included patients treated with CAR T-cell therapy. The goal was to describe the association of two management protocols with toxicity and efficacy outcomes. RESULTS: Fifty-five percent of the 40 patients assigned to early management, out of which 5% and 9% developed grade 3+ CRS and ICANS, respectively. Seventy-seven percent and 41% of these patients received tocilizumab and corticosteroids, respectively. Forty-five percent of patients were stratified as standard management, out of which 0% and 11% developed grade 3+ CRS and ICANS, respectively. Seventeen percent and 28% of these patients received tocilizumab and corticosteroids, respectively. The day +90 overall response rate (ORR) for all patients was 63%, with an ORR of 89% for those managed per early management versus 50% for those managed per standard protocol. CONCLUSION: Early use of tocilizumab and corticosteroids is effective in preventing excessive CAR-T-related toxicities with no negative impact on efficacy.

An Interpretable and Accurate Deep-Learning Diagnosis Framework Modeled With Fully and Semi-Supervised Reciprocal Learning.

The deployment of automated deep-learning classifiers in clinical practice has the potential to streamline the diagnosis process and improve the diagnosis accuracy, but the acceptance of those classifiers relies on both their accuracy and interpretability. In general, accurate deep-learning classifiers provide little model interpretability, while interpretable models do not have competitive classification accuracy. In this paper, we introduce a new deep-learning diagnosis framework, called InterNRL, that is designed to be highly accurate and interpretable. InterNRL consists of a student-teacher framework, where the student model is an interpretable prototype-based classifier (ProtoPNet) and the teacher is an accurate global image classifier (GlobalNet). The two classifiers are mutually optimised with a novel reciprocal learning paradigm in which the student ProtoPNet learns from optimal pseudo labels produced by the teacher GlobalNet, while GlobalNet learns from ProtoPNet's classification performance and pseudo labels. This reciprocal learning paradigm enables InterNRL to be flexibly optimised under both fully- and semi-supervised learning scenarios, reaching state-of-the-art classification performance in both scenarios for the tasks of breast cancer and retinal disease diagnosis. Moreover, relying on weakly-labelled training images, InterNRL also achieves superior breast cancer localisation and brain tumour segmentation results than other competing methods.

Impact of race and ethnicity on outcomes after autologous stem cell transplantation for patients with newly diagnosed multiple myeloma.

Non-Hispanic Black patients are disproportionally affected by multiple myeloma (MM) and whether efficacy outcomes after autologous stem cell transplant (ASCT) differ by race and ethnicity remains an area of active investigation. This study included 449 patients enriched with a large proportion of non-Hispanic Black patients and sought to highlight the impact of race and ethnicity on outcomes after HDT-ASCT for patients with newly diagnosed MM. We found induction chemotherapy followed by high-dose therapy-ASCT and maintenance chemotherapy is associated with long-term PFS and OS, regardless of race or ethnicity.

Feasibility, Outcomes, and Perceptions of a Virtual Group Exercise Program in Multiple Sclerosis.

BACKGROUND AND PURPOSE: Individuals with multiple sclerosis (MS) frequently report low physical activity and psychosocial support due to concerns with transportation, time, finances, access to services, and lack of caregiver support. These barriers can be addressed by online group interventions; however, utility of such programs in individuals with MS has not been examined yet. The purpose of this retrospective study was, therefore, to ( a ) investigate the feasibility, safety, and outcomes of a virtual group exercise program in individuals with MS, and ( b ) explore the participant perceptions after the program. METHODS: Retrospective data from the medical records of 17 individuals with MS (mean [SD] age = 53.5 [12.3] years, body mass index = 28.2 [7.2]) who completed the virtual 13-week group exercise program, pre- and posttraining functional status questionnaires, and the end-of-program feedback were extracted. The exercise program included aerobic, resistance, balance, and flexibility training components recommended for people with MS. Feasibility, safety, outcomes, and participant perceptions were determined by adherence to the prescribed daily exercise dosage, number of adverse events, within-group differences in self-reported functional status, and thematic analysis of the participant feedback, respectively. RESULTS: Participants were adherent (79%), reported minimal adverse effects, and demonstrated significant changes ( P < 0.05) in functional status posttraining. Several themes on the perceived barriers, facilitators, and suggestions for improvement were identified. DISCUSSION AND CONCLUSIONS: A virtual 13-week group exercise program can be feasible, safe, effective, and well received by individuals with MS. Future research should investigate the dose-response effectiveness of telehealth and compare various telehealth models of exercise training using large randomized controlled trials.Video Abstract available for more insights from the authors (see the Video, Supplemental Digital Content 1 available at: http://links.lww.com/JNPT/A434 , which demonstrates an overview of the study).

Idecabtagene vicleucel chimeric antigen receptor T-cell therapy for relapsed/refractory multiple myeloma with renal impairment.

We evaluated patients with relapsed multiple myeloma with renal impairment (RI) treated with standard of care idecabtagene vicleucel (ide-cel), as outcomes with chimeric antigen receptor (CAR) T-cell therapy are unknown in this population. RI was defined as creatinine clearance (CrCl) <50 mL/min. CrCl of <30 mL/min or dialysis dependence were defined as severe RI. The study cohort included 214 patients, 28 (13%) patients with RI, including 11 patients severe RI (dialysis, N=1). Patients with RI were older, more likely to be female and had higher likelihood of having Revised International Staging System stage 3 disease. Rates and severity of cytokine release syndrome (89% vs. 84%, grade ≥3: 7% vs. 2%) and immune effector cell-associated neurotoxicity syndrome (23% vs. 20%) were similar in patients with and without RI, respectively. Patients with RI had higher incidence of short-term grade ≥3 cytopenias, although cytopenias were similar by 3 months following CAR T-cell therapy. Renal function did not worsen after CAR T-cell therapy in patients with RI. Response rates (93% vs. 82%) and survival outcomes (median progression-free survival: 9 vs. 8 months; P=0.26) were comparable in patients with and without RI, respectively. Treatment with ide-cel is feasible in patients with RI, with a comparable safety and efficacy profile as patients without RI, with notable exception of higher short-term high-grade cytopenias.

Racial Disparities in End-Stage Kidney Disease Outcomes among Asians and Native Hawaiians and Other Pacific Islanders across Geographic Residence.

INTRODUCTION: While Asian and Native Hawaiian and other Pacific Islander (NHOPI) patients have a high prevalence of kidney disease risk factors, there are sparse data examining their end-stage kidney disease (ESKD) outcomes. As Hawaii has high representation of Asian and NHOPI individuals, we compared their ESKD outcomes based on residence in the mainland USA versus Hawaii/Pacific Islands (PIs). MATERIALS AND METHODS: Using United States Renal Data System data, we examined the impact of geographic residence in the mainland versus Hawaii/PIs on race-mortality associations among incident ESKD patients transitioning to dialysis over January 1, 2000-December 31, 2016 using Cox regression. We examined likelihood of post-dialysis kidney transplantation using Cox models and cumulative incidence curves. RESULTS: Compared with White patients in the mainland, Asian and NHOPI patients in the mainland had lower mortality: adjusted HRs (95% CIs) 0.67 (0.66-0.67) and 0.72 (0.70-0.73), respectively. When examining Asian and NHOPI patients in Hawaii/PIs, survival benefit was attenuated in Asian and diminished to the null in NHOPI patients (ref: mainland White patients). Cumulative incidence curves comparing Asian, NHOPI, and White patients showed Asian and NHOPI patients in the mainland had the highest likelihood of transplantation, whereas NHOPI and Asian patients in Hawaii/PIs had the lowest likelihood. CONCLUSION: In the mainland, Asian and NHOPI patients had lower mortality versus White patients, whereas in Hawaii/PIs, this survival benefit was diminished in Asian and mitigated in NHOPI patients. NHOPI and Asian patients in Hawaii/PIs had less transplantation versus those in the mainland. Further research is needed to uncover factors contributing to differential ESKD outcomes among Asian and NHOPI patients across geographic residence.
