Experiences of access to care, diagnosis and rehabilitation among a multiethnic patient population with long-COVID in Denmark

Abstract Background and aim The aim of the study was to explore the experiences of accessing care, diagnosis, and rehabilitation among patients with long-COVID in a multiethnic population in Denmark. Methods Qualitative research using semi-structured interviews among a purposive sample of 18 people diagnosed with long-COVID, according to the NICE guideline, in the Capital Region of Denmark. Participants were sampled to secure variation in sex, age, ethnicity, migration status and education. Our interview guide was developed using the theoretical framework of candidacy. Interviews were transcribed verbatim, and member checked, and subsequently analyzed using thematic framework analysis and NVivo software. Results The analysis generated four categories: i) living with long-COVID, ii) access to care, iii) experiences in the healthcare system, and iv) experiences with rehabilitation. A main category was identified from these categories: limited knowledge of COVID resulting in uncertainty, which challenged nearly all aspects of access to diagnosis, care and rehabilitation among the informants. In particular, ethnic minorities experienced that their motives for seeking care were questioned or had the experience of differential treatment. In general, participants perceived to be themselves responsible of recovering, while also struggling with the mental, social and work-related consequences of their long-COVID. Conclusions Our study demonstrated how the emergence of a new viral disease with unknown long-term sequelae results in a group of patients who to a great extend carry the burden of getting better themselves. More research into relevant diagnosis, care and support for long-COVID patients is needed, especially among ethnic minorities.

Food for Cancer Health Equity: The impact of a culturally tailored food voucher intervention on food insecurity among Latinx patients with cancer.

182 Background: Food insecurity disproportionately impacts immigrant, low-income, and racial and ethnic minorities with cancer. In our prior qualitative work, Latinx and multiethnic patients with food insecurity emphasized the importance of culturally-tailored food assistance interventions that could minimize stigma and maintain self-efficacy and autonomy. In collaboration with Latinx patients and community partners in Monterey County, California, we co-developed a culturally-tailored food voucher intervention. In this study, we conducted a pilot of the intervention among multiethnic and Latinx patients with cancer and tested the impact on food insecurity and health-related quality of life. Methods: We recruited low-income, racial and ethnic minority adults > 18 years of age who screened positive for food insecurity using the 2-item Hunger Vital Sign while receiving cancer treatment in a clinic in Monterey County, CA between July 2023 until August 2023. All participants who consented to participate received $40 monthly grocery store gift cards redeemable at a variety of local retailers for 6 months in addition to usual care provided by trained community health workers who assisted with other health-related social needs. We conducted validated surveys at baseline (time of enrollment) and 6-month follow-up (post-intervention) assessing demographics, food behaviors, food insecurity, and health-related quality of life, as well as feasibility and acceptability of the intervention. We compared pre- and post-intervention proportions with food insecurity using McNemars tests and change in health-related quality of life using paired t-tests. Results: Of the 30 study participants enrolled, 27 (90%) were Latinx; 24 (80%) spoke Spanish as their preferred language; 16 (53%) had advanced (stage 3 or 4) cancer; 12 (40%) were retired or unemployed; 10 (33%) were disabled; 20 (67%) reported a household income < $35,000 USD. Of the 26 (87%) participants who completed post-intervention surveys, the proportion with food insecurity decreased from 100% to 65% (95% CI 0.60-0.77; p = 0.01); 100% adhered to recommended treatment; and health-related quality of life scores increased by 8 points from 71.9 +/-16.1 to 79.5+/- 10.5 (p = 0.02) from baseline. All (100%) participants rated the program as feasible and acceptable in post-intervention surveys. Conclusions: This culturally-tailored food voucher intervention was associated with reductions in food insecurity and improvements in health-related quality of life among low-income Latinx patients with cancer. This intervention may represent an effective and acceptable approach to overcome food insecurity in Latinx and multiethnic patients with cancer.

Outcomes of Pro Re Nata versus Treat-and-Extend Anti-VEGF Injections for Myopic Macular Neovascularization in Multiethnic Patients in the United States.

To compare visual outcomes and recurrence rates between pro re nata (PRN), treat-and-extend and stop (TES), and treat-and-extend with chronic maintenance dosing (TEM) regimens of anti-vascular endothelial growth factor (VEGF) injections for myopic macular neovascularization (MNV) in multiethnic patients. This retrospective study included patients treated with PRN, TES, or TEM for myopic MNV using intravitreal bevacizumab or ranibizumab. The primary outcome measure was visual improvement at 12 months. We included 127 eyes of 117 patients (75 females and 42 males). The mean follow-up duration was 37.9 months. We compared the outcomes of PRN (47 eyes [37%]), TES (52 eyes [41%]), and TEM (28 eyes [22%]). All groups showed significant visual improvement at 12 months and at the final follow-up (all P<0.05). Visual outcomes did not differ significantly between the three groups at 12 months and final follow-up (all P>0.05). However, the number of eyes with recurrences was significantly higher in the PRN group and significantly lower in the TEM group during follow-up (38%, 21%, and 11% in the PRN, TES, and TEM groups, respectively; P=0.020). The PRN group received the fewest injections during follow-up (5.3, 10.9, and 19.9 injections in the PRN, TES, and TEM groups respectively; P<0.001). Anti-VEGF injections with PRN, TES, or TEM regimens are effective for myopic MNV and have comparable visual outcomes. Since PRN provides favorable outcomes with fewer injections, it should be the first-line approach. However, a treat-and-extend approach with TES and TEM may be an option given individual patient factors.

Four years of real-world sexual function outcomes after Rezum therapy in men with and without baseline erectile dysfunction.

Rezum alleviates lower urinary tract symptoms secondary to benign prostatic hyperplasia (BPH) while preserving sexual function, but long-term sexual function outcomes are lacking in patients with baseline erectile dysfunction (ED). The study sought to analyze 4years of real-world sexual function outcomes of Rezum using the International Index of Erectile Function (IIEF) questionnaire, stratified by baseline ED status. Participants included multiethnic Rezum-treated patients from a single outpatient office. IIEF domains and BPH medication usage were compared at baseline and 6, 12, and 48months using t tests, Mann-Whitney U tests, chi-square tests, and Wilcoxon signed rank tests. Primary outcomes over 4years included the IIEF functional domains (erectile function [EF], orgasmic function [OF], sexual desire [SD], intercourse satisfaction [IS], overall satisfaction [OS]) and BPH medication usage. A total of 91 patients were included: 40 (44%) in the ED cohort and 51 (56%) in the no ED cohort. History of diabetes was more prevalent in the ED cohort (35% vs 15.7%; P = .048). Baseline scores in the EF, OF, IS, and OS domains were lower in the ED cohort. Compared with baseline, there were no significant changes in any IIEF domains in either cohort at 6months. At 12months, the ED cohort had significant percent decreases in OF (-25%; P = .02), SD (-22.2%; P = .04), and OS (-33.3%; P = .004); the no ED cohort had a significant percent increase in EF (5%; P = .04). At 48months, the no ED cohort had no significant changes in any IIEF domains, while the ED cohort had significant percent increases in EF (30%; P = .01), SD (22.5%; P = .02), IS (20%; P = .01), and OS (58.3%; P = .008). Both cohorts significantly discontinued BPH medications at all follow-ups. At 48months, there were no cases of de novo ED in the no ED cohort. As modern BPH therapies continue to demonstrate efficacy in alleviating lower urinary tract symptoms, the preservation or improvement of sexual function emerges as an increasingly important consideration for patients, with our study suggesting Rezum as a compelling option. Our study has the strength of long-term Rezum outcomes in an ethnically diverse patient population, stratified by the presence of baseline ED, but is limited by retrospective design, single-center nature, and small sample sizes at long-term follow-ups. Rezum preserved long-term sexual function in patients without baseline ED and improved sexual function in those with baseline ED; however, individuals with ED may experience temporary decreases in sexual function at 12months.

Food for cancer health equity: The impact of a culturally tailored food voucher intervention on food insecurity among Latinx patients with cancer.

1544 Background: Food insecurity disproportionately impacts immigrant, low-income, and racial and ethnic minorities with cancer.

Conclusions: This culturally tailored food voucher intervention was associated with reductions in food insecurity and improvements in health-related quality of life among low-income Latinx patients with cancer. This intervention may represent an effective approach to overcome food insecurity in Latinx and multiethnic patients with cancer.

Multi-ethnic genome-wide association study to identify a novel locus for susceptibility to immune-related adverse events from immune checkpoint inhibitors.

3090 Background: Immune-related adverse events (IrAEs) arising from immune checkpoint inhibitors (ICIs) can be unpredictable. As genomic variation underlies both disease susceptibility and drug responses, genomic markers may predict for the development of IrAEs. We perform a pioneering pharmacogenomic study across a multi-ethnic Asian patient population to uncover genomic biomarkers associated with IrAEs from ICIs. Methods: From March 2018 – July 2023, cancer patients treated with ICIs from the National University Cancer Institute Singapore and Tan Tock Seng Hospital were recruited. IrAEs were characterized and graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (CTCAE) version 5. DNA was extracted and genotyped by Infinium Global Screening Array (700K markers). Statistical analyses were performed by SVS/HelixTree, PLINK and R. Genetic association was performed by logistic regression (additive model), accounting for all possible confounding factors. Bonferroni corrected P &lt; 1.28E-07 (0.05/390,925 SNPs passed QC) was considered statistically significant. Results: Genome-wide association study (GWAS) was conducted amongst 507 patients of Asian Ancestry (Chinese, Malay, Indian and Others). Median age was 63. Majority were male (66.5%), Chinese (76.7%), ECOG PS 0-1 (40.1%) and had stage IV cancer at diagnosis (67.2%). Non-small cell lung cancer (37.1%), renal cell carcinoma (12.2%) and hepatocellular carcinoma (7.7%) were the three most common cancers. Top four ICIs used were pembrolizumab, nivolumab, durvalumab and atezolizumab, respectively (47.1%, 23.9%, 12.5%, 11.3%). 0.8% of patients received dual ICIs concurrently. Median duration of treatment was 142 days and median follow-up was 147 days. IrAEs were seen in 43.7% of patients. Skin (24.1%), endocrine (8.1%) and hepatotoxicity (6.1%) were the most common IrAEs. 4.9% of patients had grade ≥3 toxicity, of which skin (3.6%), hepatotoxicity (3.0%) and pulmonary toxicity (1.8%) were the most common. Multi-ethnic GWAS analysis identified one potential novel genetic locus associated with CTCAE grade ≥3 IrAEs. chr3:163402331 rs146525069; P = 7.29E-08, OR (95%CI) = 17.08 (5.40- 54.04); minor allele = A, 10.91% in Cases vs 0.71% in Controls. Conclusions: This pharmacogenomics GWAS uncovered a novel locus for susceptibility to serious immune-related adverse events from immune checkpoint inhibitors. Further pharmacogenomic discovery/replication and functional validation studies are currently on-ongoing. Our study provides a potential biological mechanism for IrAEs and a step towards more effective clinical translation of pharmacogenetic testing to personalize ICI use.

Tranexamic acid versus oxytocin prophylaxis in reducing post-partum blood loss, in low-risk pregnant women: TRANOXY STUDY, a phase III randomized clinical trial

To assess the equivalence of tranexamic acid (TRAN) versus synthetic oxytocin (OXY) in reducing post-partum blood loss, in full-term patients (37-42 weeks), at low risk of post-partum hemorrhage, with vaginal childbirth. Phase III, randomized (1:1), open-label, longitudinal, multi-center, prospective clinical trial (Prot. n 63209, ClinicalTrials.gov Identifier: NCT02775773). From January 7, 2020, to June 30, 2023, a total of 256 women were enrolled at two general urban community hospitals in Italy, serving a multi-ethnic patient population with National Health Insurance. The primary outcome was to explore a potential equivalence between the two treatments (OXY and TRAN) in preventing total blood loss. Therefore, we randomized 231 women into two groups: Group A (OXY), 127 women who were administered 10UI intramuscularly within 5min from childbirth; Group B (TRAN), 104 women to whom 1-g slow intravenous infusion was administered within 5min from childbirth. At the time of delivery, mean blood loss for OXY group versus TRAN group was 269.12mL versus 263.88mL, respectively, with equivalence between the two groups. Similarly, there was equivalence in total blood loss between the OXY and the TRAN group (397.66mL versus 405.64mL, respectively. No statistical differences between Hb levels at admission and discharge in the two groups were reported. No difference was found in terms of additional uterotonic and surgical therapies between the two groups of patients. Neither group showed thrombotic complications at check-up performed after 7 days or after a questionnaire regarding adverse effects, subjected after 40 days. The study shows the equivalence of tranexamic acid versus synthetic oxytocin in post-partum blood loss prophylaxis in term patients at low risk of PPH with vaginal childbirth. The safety profiles of OXY and TRAN were similar. None.

Distribution of mitochondrial MT-RNR1, MT-TL1, MT-TS1, MT-TK and MT-TE genes variants associated with hearing loss in Southwestern China

BackgroundMaternally inherited hearing loss has been associated with mitochondrial genes, including MT-RNR1, MT-TL1, MT-TS1, MT-TK and MT-TE. Among these genes, MT-RNR1 is known to be a hotspot for pathogenic variants related to aminoglycoside ototoxicity and nonsyndromic hearing loss. However, the frequency and spectrum of variants in these genes, particularly in multi-ethnic hearing loss patients from Southwestern China, are still not fully understood. MethodsIn this study, we enrolled 460 hearing loss patients from various ethnic backgrounds (Han, Yi, Dai, Hani, etc.) in Southwestern China. Next-generation sequencing was used to analyze the mitochondrial MT-RNR1, MT-TL1, MT-TS1, MT-TK and MT-TE genes. Subsequently, bioinformatical methods were employed to evaluate the identified variants. ResultsAmong the patients with hearing loss, we identified 70 variants in MT-RNR1 (78.6 %, 55/70), MT-TL1 (4.3 %, 3/70), MT-TS1 (4.3 %, 3/70), MT-TK (7.1 %, 5/70) and MT-TE (5.7 %, 4/70) genes. We found that 15 variants were associated with hearing loss, including m.1555 A > G and m.1095 T > C. Additionally, we discovered three reported mitochondrial variants (m.676 G > A, m.7465 insC, and m.7474 A > G) newly correlated with hearing loss. Notably, certain pathogenic variants, such as m.1555 A > G, displayed non-consistent distributions among the multi-ethnic patients with hearing loss. Furthermore, the number of variants associated with hearing loss was higher in the Sinitic group (n = 181) and Tibeto-Burman group (n = 215) compared to the Kra-Dai group (n = 38) and Hmong-Mien group (n = 26). ConclusionsThis present study revealed the distribution of mitochondrial variants linked to hearing loss across various ethnic groups in Southwestern China. These data suggest a potential correlation between the distribution of mitochondrial variants associated with hearing loss and ethnic genetic backgrounds.

Abstract PO3-09-02: Identifying risk factors for trastuzumab-induced cardiotoxicity among multi-ethnic women with HER2-positive early-stage breast cancer

Abstract Introduction: While trastuzumab, a HER2-targeted therapy for patients with HER2-positive breast cancer, has been shown to improve disease-free and overall survival rates, it also confers the risk of significant morbidity in the way of trastuzumab-induced cardiotoxicity (TIC). TIC may present as asymptomatic decline in left ventricular ejection fraction (LVEF) or as symptomatic heart failure. Given that racial/ethnic minorities are at higher risk for cardiovascular disease (CVD) compared to non-Hispanic Whites, our objective was to assess racial/ethnic differences in TIC and LVEF recovery among multi-ethnic patients with HER2-positive early-stage breast cancer. Methods: We conducted a retrospective cohort study including patients diagnosed with stage I-III HER2-positive breast cancer between 2007-2022 who had received adjuvant trastuzumab therapy at Columbia University Irving Medical Center (CUIMC) in New York, NY. TIC was defined as &amp;gt;10% decrease in LVEF to an overall LVEF&amp;lt; 50% and was confirmed by a minimum of two serial echocardiograms, whereas LVEF recovery was defined as a return to a LVEF &amp;gt;50%. Descriptive statistics, univariate and multivariate logistic regression analyses were conducted to estimate odds ratios (OR) and 95% confidence intervals (CI) for the associations between sociodemographic factors, tumor characteristics, treatment regimens, and CVD risk factors with the main outcome of TIC. Results: In the final cohort (N=500), median age was 53 years (IQR: 45.0-62.0) with 36.6% non-Hispanic White (NHW), 15.8% non-Hispanic Black (NHB), 27.8% Hispanic, and 19.8% Asian/Pacific Islander/Other. About 68.2% of patients received adjuvant radiation therapy, 30.2% were treated with anthracyclines, 37.8% with pertuzumab, 4.6% with T-DM1 and 69.0% with endocrine therapy. Fifty-three (10.6%) patients developed TIC, half of which experienced LVEF recovery. Compared to NHW, NHB patients had a higher rate of TIC (9.3% vs. 17.7%, respectively) and lower rate of LVEF recovery (70.6% vs. 21.4 % in those with TIC, respectively). On multivariable analysis, increasing age, lower LVEF at baseline, anthracycline exposure, and coronary artery disease (CAD) were associated with TIC (see Table). We found no association between TIC and use of pertuzumab or T-DM1. Discussion: In our racially/ethnically diverse study population, we found an incidence of TIC comparable to previous clinical studies. NHB patients had double the incidence of TIC and a lower incidence of LVEF recovery when compared to NHW patients. Given the observed racial disparities in TIC and LVEF recovery, NHB patients may require closer cardiac monitoring and restricted use of anthracyclines with adjuvant trastuzumab treatment. More research on cardiotoxicity associated with newer forms of HER2-targeted therapies is necessary.

Core planar cell polarity genes VANGL1 and VANGL2 in predisposition to congenital vertebral malformations

Congenital scoliosis (CS), affecting approximately 0.5 to 1 in 1,000 live births, is commonly caused by congenital vertebral malformations (CVMs) arising from aberrant somitogenesis or somite differentiation. While Wnt/ß-catenin signaling has been implicated in somite development, the function of Wnt/planar cell polarity (Wnt/PCP) signaling in this process remains unclear. Here, we investigated the role of Vangl1 and Vangl2 in vertebral development and found that their deletion causes vertebral anomalies resembling human CVMs. Analysis of exome sequencing data from multiethnic CS patients revealed a number of rare and deleterious variants in VANGL1 and VANGL2, many of which exhibited loss-of-function and dominant-negative effects. Zebrafish models confirmed the pathogenicity of these variants. Furthermore, we found that Vangl1 knock-in (p.R258H) mice exhibited vertebral malformations in a Vangl gene dose- and environment-dependent manner. Our findings highlight critical roles for PCP signaling in vertebral development and predisposition to CVMs in CS patients, providing insights into the molecular mechanisms underlying this disorder.

Functional Analysis of cag Pathogenicity Island Diversity in Helicobacter pylori Isolated from Multi-Ethnic Patients in Malaysia

cagPAI is an important pathogenic marker contributing to disease severity caused by H. pylori infection, encoding proteins for type four secretion systems (T4SS) and the pro-inflammatory cytokines (IL-8) induction in infected host. The heterogeneity of cagPAI genes results in different clinical outcomes in H. pylori infection. The aim of this study was to investigate the functional diversity of cagPAI genes in clinical H. pylori strains isolated from patients with gastroduodenal diseases. Among the isolates investigated, 6 out of 27 (22.2%) harbor intact cagPAI, 3 strains (11.1%) have complete absence of cagPAI, and 18 strains (66.7%) contain a partially deleted island. IL-8 concentration is observed significantly higher among cagPAI-positive isolates (P = 0.045). Of note, IL-8 secretion in the gastric cells infected with H. pylori strains isolated from Malay patients was significantly higher than the gastric cells infected with the strains from non-Malay patients (P = 0.046). The secretion of IL-8 appears in similarly high among intact and partially deleted cagPAI isolates. East Asian cagA isolates induce a notably higher level of IL-8 than that of Western cagA. Inflammatory activities are observed and IL-8 concentration in the milder stage was found in significantly higher quantities than in the severe stage (P = 0.027). The ‘hummingbird’ phenotype was observed to cause severe effects in infected cells with cagPAI-intact H. pylori. The genetic variability of cagPAI isolates from multi-ethnicity patients may have unique implications for disease outcomes with respect to proinflammatory secretion.

Drug-induced liver injury (DILI) ascribed to non-steroidal anti-inflammatory drugs (NSAIDs) in the USA-Update with genetic correlations.

To describe patients with NSAID-DILI, including genetic factors associated with idiosyncratic DILI. In DILIN, subjects with presumed DILI are enrolled and followed for at least 6 months. Causality is adjudicated by a Delphic approach. HLA sequencing of multiethnic NSAID-DILI patients and HLA allele imputation of matching population controls were performed following overall, class and drug-based association analysis. Significant results were tested in a non-Hispanic White (NHW) case-control replication cohort. Between September 2004 and March 2022, causality was adjudicated in 2498, and 55 (41 [75%] women) were assessed as likely due to NSAIDs. Median age at onset was 55 y (range 22-83 y). Diclofenac was the causative drug in 29, celecoxib in 7, ibuprofen in 5, etodolac and meloxicam each in 4. Except for meloxicam and oxaprozin (n = 2), the liver injury was hepatocellular with median R 15-25. HLA-DRB1*04:03 and HLA-B*35:03 were significantly more frequent in NSAID-DILI patients than in non-NSAID DILI controls. Interestingly, 85% of the HLA-DRB1*04:03 carriers developed DILI due to the use of acetic acid derivative NSAIDs, supporting the hypothesis that HLA-DRB1*04:03 could be a drug and/or class risk factor. HLA-B*35:03 but not HLA-DRB1*04:03 association was confirmed in the independent NHW replication cohort, which was largely driven by diclofenac. Despite prevalent use, NSAID-DILI is infrequent in the United States. Diclofenac is the most commonly implicated, and adherence to warnings of risk and close observation are recommended. The increased frequency of HLA-B*35:03 and DRB1*04:03, driven by diclofenac, suggests the importance of immune-mediated responses.

Informing Dementia Support Programs That Serve Low-Income, Multilingual Communities in a Safety Net Health System: Use of Focus Groups to Identify Specific Needs.

The Centers of Medicare and Medicaid Services recently announced a new voluntary nationwide model. This model aims to provide comprehensive, standard care for people living with dementia and their unpaid caregivers and to enhance health equity in dementia care. However, little is known about the needs of older adults with dementia and their caregivers in a multiethnic and multicultural patient population of a safety net health system. The aim of this study is to include their voices. We conducted four focus groups in English and Spanish to investigate the common needs and barriers unique to the care of patients within the Los Angeles County healthcare system. Using qualitative, iterative analyses of the transcripts, we identified four domains of concern from the dyads (persons with dementia and their caregivers): need for education for dyad-centered care, barriers to resources, dyad safety, and caregiver burden and insight. These domains are interconnected, and the way this patient population experiences these domains may differ compared to those in well-resourced or predominantly English-speaking healthcare settings. Therefore, the identified domains serve as potential building blocks for dementia support programs inclusive of underserved, multicultural populations.

Kidney function trajectories, associated factors, and outcomes in multiethnic Asian patients with type 2 diabetes.

We examined the trajectory of estimated glomerular filtrate rate (eGFR), associated risk factors, and its relationship with end-stage kidney disease (ESKD) among a multiethnic patient population with type 2 diabetes in Singapore. A follow-up study included 62 080 individuals with type 2 diabetes aged ≥18 years in a multi-institutional SingHealth Diabetes Registry between 2013 and 2019. eGFR trajectories were analyzed using latent class linear mixed models. Factors associated with eGFR trajectories were evaluated using multinomial logistic regression. The association of eGFR trajectories with ESKD was assessed via competing risk models. Trajectory of kidney function, determined by eGFR, was nonlinear. The trajectory pattern was classified as stable initially then gradual decline (75%), progressive decline (21.9%), and rapid decline (3.1%). Younger age, female sex, Malay ethnicity, lower-income housing type, current smoking, higher glycated hemoglobin, lower low-density lipoprotein, higher triglyceride, uncontrolled blood pressure, albuminuria, cardiovascular disease, hypertension, and higher eGFR levels each were associated with progressive or rapid decline. Compared with the trajectory of stable initially then gradual eGFR decline, progressive decline increased the hazard of ESKD by 6.14-fold (95% confidence interval [CI]: 4.96-7.61)) and rapid decline by 82.55 folds (95% CI: 55.90-121.89). Three nonlinear trajectory classes of kidney function were identified among multiethnic individuals with type 2 diabetes in Singapore. About one in four individuals had a progressive or rapid decline in eGFR. Our results suggest that eGFR trajectories are correlated with multiple social and modifiable risk factors and inform the risk of ESKD.

Self-Efficacy in Patients With Hypertension and Their Perceived Usage of Patient Portals.

Self-efficacy in individuals optimizes their hypertension management. Electronic patient portals are being increasingly used to support chronic disease management, as they raise the health literacy of patients and enable them in self-management. However, the association between the use of patient portals and self-efficacy in hypertension management remains unclear. The study aimed to determine the association between self-efficacy among patients with hypertension who are managed in primary care and their demographic characteristics and usage patterns of patient portals. A cross-sectional survey was conducted at a public primary care clinic in urban Singapore. Multi-ethnic adult patients with hypertension were invited to participate in a self-administered electronic questionnaire. Chi-square test was performed for bivariate analysis; adjusted logistic regression models were used for factors with P value <.1. A total of 310 patients (66.8% Chinese, 55.5% males, mean age of 63.1 years) completed the survey. Patient portal users had higher self-efficacy scores than non-users (mean score=63 vs 60, maximum = 80, P = .011). The factors associated with increased patient portal access included younger age <65 years (absolute odds ratio [AOR] = 2.634, 95%CI = 1.432-4.847; P = .002), monthly income >$5000 (AOR = 2.324, 95%CI = 1.104-4.892; P = .026), and post-secondary education level (AOR = 3.128, 95%CI = 1.675-5.839; P < .001). Most patients (93.1%) used the portal to check medical appointments but only1.3% of them used it to record home blood pressure measurements (HBPM). Patient portal usage was associated with higher self-efficacy scores in patients with hypertension. These users were younger, more educated, and earned more than the non-users, but only 1.3% of them used it for HBPM documentation.

Patient-caregiver twinned mobile phone application to promote medication adherence

Background Poor medication adherence (MA) is prevalent globally. MA assessment, often based on scales or pill count, lacks actionability. A mobile application (app), MediEasy, targeting patients on multiple daily medications, has been developed to engage their caregivers to enhance their MA. Objectives This pilot single-arm study aimed to determine the feasibility, acceptability, utility and glycaemic control of the MediEasy-app by patients with type-2 diabetes mellitus and their caregivers. Methods 20 Multi-ethnic Asian patients aged 51 to 70 years with suboptimal glycaemic control (HbA1c&gt;7.5%) and their caregivers were recruited at a Primary care outpatient clinic in Singapore. The Medieasy app that contains the following major functionalities such as the alerts to take medications, embedded medication details, personalized dosing options (such as frequency and scheduling dosage settings) is twinned to their designated caregivers. The Caregivers can remind the patients who missed the scheduled medication intake when the paired device was alerted. Results 85% (17/20) of the participants used the app for the entire 4 weeks, reflecting feasibility; 3 dropped out due to technical glitches or failure to adhere to protocol. The app was activated with an average of 2.8 times per day showing adequate utility. The 17 participants and their caregivers agreed that the app supported medication adherence. Their mean HbA1c decreased by 0.2% after 12 weeks of app usage. Conclusions The results showed feasibility, utility and acceptability of the MediEasy-app, with improved glycaemic control after its usage.

Evaluation of a Prognostic 23-Gene Expression Panel in a Set of 390 Multiethnic Hodgkin Lymphoma Patients

Classic Hodgkin lymphoma (CHL) is a curable lymphoma with unique epidemiological features, including rare neoplastic cells, and an adolescent/young adult age (AYA) incidence peak higher in females, correlated with socioeconomic status. We previously reported that RNA expression measured in formalin-fixed paraffin-embedded (FFPE) tissues using a panel of 23 immune response genes was associated with 5-year overall survival (OS) in predominantly White/European advanced staged CHL patients treated with ABVD chemotherapy (Scott et al., 2013). Here, we conducted a study to evaluate if the 23-gene expression panel predicted 5-year OS in a real-world set of FFPE tumor tissue from racially/ethnically diverse populations in the U.S. and Mexico from the Multi- Ethnic Study of Hodgkin Lymphoma (MESH). Methods: We collected tumor blocks from 891 patients from 9 hospitals and 2 Residual Tissue Repositories in the U.S. and Mexico. Demographic and clinical data, including survival by month, age at diagnosis, birth year, race/ethnicity, sex, histology were abstracted. Patients were diagnosed from 1978 to 2018. CHL diagnoses and histological subtypes were validated by histopathology review. RNA was extracted and NanoString gene expression profiling was performed using 250-gene codeset including the published 23-gene expression (GE) panel (Scott et. al., 2013). 390 cases passed QC after applying a modified normalization protocol (Chan et.al., 2017). The multiethnic risk index was derived from a linear equation of the log 2 GE in MESH multiplied by the established regression coefficients (Scott et al., 2013). Next, we examined a dichotomized score using a cut-off value at the 75 th percentile. Both were tested for association with 5-year OS using a Cox proportional hazards model using R software 4.3.0 version adjusting for age as a continuous and categorical variable (15-39 and 40+ years), type of hospital that provided the samples, sex, EBV tumor status (assigned using EBER2), race/ethnicity, and histology. The 5-year OS was computed by right-censoring any patient that survived longer than 5 years. Proportionality assumptions were tested (using an alpha level of 0.05). Stratified models by categorical age and race/ethnicity were adjusted for patient demographical variables and effect heterogeneity was examined using a t-test. Result: The analytic set comprised 47% females and 44% Hispanic, 24% White, 20% Black, 9% Asian, and 3% Pacific Islander/Native Hawaiians. 62% were 15-39 years and 32% 40+ years at diagnosis. The multivariate analysis, excluding age, indicated an association between the risk index and 5-year OS (HR =1.41 (1.08, 1.93), p=0.01). However, including age attenuated the association (HR=1.18 (0.89, 1.57), p=0.25). When stratified by age categories, the continuous risk index was associated with 5-year OS only in the older age group: 15-39 years (HR = 0.89 (0.54, 1.47), p=0.65), and &amp;gt;40 years (HR = 1.47 (1.08, 2.01), p=0.02), indicating effect heterogeneity by age groups (p=0.09). We did not observe significant effect heterogeneity by EBV status (p=0.6), race/ethnicity (p=0.72), nor sex (p=0.33). When the dichotomized score was examined, the model was attenuated after adjusting for age, but stratification analysis showed an association in the older adults (HR= 2.8 (1.42, 5.51), p&amp;lt;0.01) with significant effect heterogeneity across age (p=0.02) (Figure 1). Evaluating the association between individual genes and OS, we found effect heterogeneity by age; two genes from the 23-gene panel indicated protective effects in the AYA but hazardous in older adults: B2M (p effect heterogeneity' =0.048) and APOL6 (p'=0.059). Individual genes with heterogeneity of association across race/ethnicity included RNF144B (p' =0.0021) with increased hazards in Whites compared to Blacks, whereas WDR83 (p'=0.018), PRF1 (p'=0.0018), LYZ (p'=0.0028) had higher hazards in Blacks compared to Whites, and RAPGEF2 (p'=0.036) had higher hazards in Hispanics compared to Whites. Conclusion: The risk index and dichotomized score derived from the previously developed 23-gene panel was significantly associated with OS among &amp;gt;40 year age group, with evidence of age effect heterogeneity. We detected 2 genes with an association that varied by age, and five across race/ethnicity, suggesting the importance of including diverse racial/ethnic and age groups in CHL patient populations when developing predictive models.
