Social Risk of Pregnant Women at a Community Health Center: An Application of the PRAPARE Assessment Tool

Community health centers (CHCs) screen patients for social determinants of health (SDoH). The study's purpose was to assess the relationship between demographic factors and unmet social needs (SDoH risk) among pregnant mothers. Patient data from 345 pregnant women between January 2019-December 2020 assessed SDoH risk, using the Protocol for Responding to and Assessing Patients' Assets, Risks, and Experiences (PRAPARE) tool. Chi-square analyses explored relationships between social needs and demographic factors, and a multivariate logistic regression examined associations between these variables controlling for covariates. Hispanic patients and those who preferred to speak Spanish had 2.35 and 5.39 times the odds, respectively as non-Hispanic Whites and English speakers of having moderate/high/urgent SDoH risks. Mothers who had not completed high school had increased odds (aOR = 7.38) of SDoH risk. By identifying indicators that increase social risk level, CHCs can connect patients to essential social services, improving the downstream health of mothers and children.

Association of the COVID-19 Pandemic With Women, Infants, and Children (WIC) Receipt Among Pregnant Individuals: United States, 2016-2022

Objectives. To evaluate the effect of COVID-19 on Special Supplemental Nutrition Program for Women, Infants, and Children (WIC) receipt among pregnant individuals overall and by race/ethnicity. Methods. We measured changes in WIC receipt among Medicaid-covered births (n = 10 484 697) from the US National Center for Health Statistics Natality Files (2016-2022). Our interrupted time series logistic model included a continuous monthly variable, a binary post-COVID variable, and a continuous slope shift variable. We additionally fit separate models for each race/ethnicity relative to White individuals, using interaction terms between the time series variables and race/ethnicity. Results. We found decreases in WIC receipt (adjusted odds ratio [AOR] = 0.899; P < .001) from before COVID (66.6%) to after COVID (57.9%). There were larger post-COVID decreases for American Indian/Alaska Native (AOR = 0.850; P < .001), Native Hawaiian/Other Pacific Islander (AOR = 0.877; P = .003), Black (AOR = 0.974; P < .001), and Hispanic (AOR = 0.972, P < .001) individuals relative to White individuals. Conclusions. The greater reductions in WIC receipt among minoritized individuals highlights a pathway through which the pandemic may have widened gaps in already disparate maternal and infant health. Public Health Implications. Continued efforts to increase WIC utilization are needed overall and among minoritized populations.

The development of a regional network for health care research in Hamburg, Germany

Background

At the University Medical Center Hamburg-Eppendorf (UKE), health care research has been established as one of five research priorities recommended by the Research Council with the founding of the Center for Health Care Research (CHCR) in 2006. The CHCR was involved in numerous research projects with the focus on strengthening regional networking. Despite the numerous initiatives, there is still potential for improvement with regard to a systematic and sustainable exchange in the region of Hamburg, Germany.

Methods

These requirements led to the initiation of the ‘Hamburg Network Health Services Research (HAM-NET)'. The mission of HAM-NET is to build an open forum for all relevant institutions, to concentrate their interests and needs in health services research and to promote and conduct innovative, efficient, needs-based and patient-centred health services research projects in the metropolitan area of Hamburg. Three main tasks were appointed: 1) linking health care research to relevant regional institutions, 2) promoting research activities and new fields of research and 3) using methodological expertise to promote young scientists.

Results

By today 40 institutions from all sectors of health care joined HAM-NET. The regularly general meetings offer exchange and advice. Internal communication is promoted by mailing lists and newsletters. Also, HAM-NET presents itself with a website, logo and by organizing recurring events and participating in international and national congresses and networks. Within two funding phases a total of four overarching research projects were developed and implemented. Furthermore, a person with lived experience committee was established.

Conclusions

For the further development of health care research as one the core disciplines of public health a regional network with an efficient infrastructure is needed. HAM-NET promotes this with the implementation of an innovative, efficient and patient-oriented network.

Key messages

• Regional networks help to integrate multiple public health initiatives and community stakeholders.

• Public health networks can be established on multidisciplinary cooperations in different out- and inpatient sector levels.

Impact of atrial fibrillation on outcome of percutaneous mitral valve repair (PMVR) procedure

Background

Limited evidence exists regarding the impact of atrial fibrillation (AF) on outcomes after percutaneous mitral valve repair (PMVR). The aim of the present study was to compare 1-year clinical outcomes following PMVR in patients with and without AF.

Methods

426 patients with PMVR for severe MR were included in the COburg MItraclip (COMI) registry between 2016 and 2021. Patients were divided into an AF group (group A, n=284) and a non-AF group (group B, n=142). Clinical profiles, PMVR procedure characteristics and the clinical follow-up were compared between the two groups.

Results

Patients with AF were older (79.3±6.3 [AF] vs. 77.8±8 years [non-AF], p=0.03), had higher N-terminal B-type natriuretic peptide levels (NT-pro BNP: 5675±5544.2 vs 8516±11184.5, p=0.004), more often a coronary artery disease (62% vs 38%, p=0.03) and had a lower stroke risk (CHA2DS2-VASc score: 4.6±1.2 vs 4.9±1.3, p=0.01). There were no significant differences between groups with regard to the gender, logistic Euroscore or prevalence of chronic heart failure, hypertension, diabetes mellitus or severe mitral regurgitation. Acute procedural success (post-procedural 2. MR, 95.1% vs. 94.4%; p=0.76) and procedure-related major complications were similar.

There were no significant differences in 1-year MACCE (death, MI, stroke, bleeding), health-related quality of life or clinical improvement.

Conclusion

In patients with mitral regurgitation who underwent PMVR, AF is common and appears not to have a relevant negative impact on the clinical outcome at 1 year compared to patients with sinus rhythm.

P981Predictor factors and the prognostic role of persistent pulmonary veins isolation in patients with arrhythmia recurrence necessitating a second ablation procedure

Aims

Pulmonary vein isolation (PVI) is the treatment of choice in patients (pts) with symptomatic atrial fibrillation. Durable pulmonary veins isolation (PVI) seems to be associated with a lower risk of AF recurrence, but the predictor factors of persistent PVI are still uncertain. We aimed to determinate the predictor factors and the prognostic role of persistent pulmonary veins isolation in pts with arrhythmia recurrence necessitating a second ablation procedure.

Methods and results

Our Study included 102 pts (65.7% male, 65±8 years old, 75.5% persistent AF) with arrhythmia recurrence, whom underwent a Redo-PVI between October 2016 and Mars 2018. Patients were divided into two groups regarding the persistence of PVI. Group 1 included 20 pts with persistent PVI and Group 2 included 82 pts with reconnection of at least one PV. The clinical profile, ablation data and three months arrhythmia recurrence were analyzed.

There were no statistical differences in terms of clinical profile between the two groups of pts (age; p=0.513, gender; p=0.299, BMI; p=0.077, diabetes mellitus; p=0.621, coronary artery disease; p=0.787; arterial hypertension; p=0.732; left ventricle ejection fraction; p=0.323 and left atrial diameter; p=0.5). Patients in group 1 presented more often with atrial tachycardia compared to group 2 Patients (30% versus 7.3%; p=0.014). Regarding the ablation data, there were no differences between the two groups in terms of procedure time (p=0.710) but the ablation time was longer in group 2 patients (29.1±13.7 versus 20.8±10.5 min. p=0.031). Low voltage areas (LVA) acquired by bipolar electroanatomical mapping were more often and diffuse in group 1 patients (70% versus 40.3%; p=0.050). The three months arrhythmia recurrence after Redo-Ablation was the same between the two groups (p=1.000).

Conclusion

The type of arrhythmia recurrence and low voltage areas are predictor factors of persistent pulmonary veins isolation in patients with arrhythmia recurrence necessitating a second ablation procedure. This fact can help in planning the second ablation procedure. Persistent PVI seems to have no prognostic role regarding the three months arrhythmia recurrence after Redo-Ablation.

Abstract P1-11-10: Efficacy of NEPA as antiemetic prophylaxis in breast cancer patients receiving highly or moderately emetogenic chemotherapy – Interim results of a German prospective, non-interventional study

Background

The oral fixed dose combination of netupitant and palonosetron NEPA has been approved for the prevention of acute and delayed chemotherapy-induced nausea and vomiting (CINV) in cancer patients receiving cisplatin-based highly emetogenic (HEC) or moderately emetogenic chemotherapy (MEC). The primary objective of the prospective, non-interventional study (NIS) AkyPRO is the evaluation of quality of life in adults receiving MEC or HEC and NEPA for CINV prevention. Secondary endpoints are efficacy and safety of NEPA. Here we present an interim analysis of NEPA efficacy in the subgroup of breast cancer patients, who represent the largest subgroup (66%) of enrolled patients. Since September 2015, 2427 patients have been enrolled, of whom 986 are breast cancer patients.

Methods

The NIS has been designed to evaluate NEPA in 2,500 cancer patients receiving single day or two day MEC or HEC. QoL is recorded by FLIE questionnaires. Efficacy (complete response (CR, no vomiting, no rescue medication)), additional medication, and adverse events are recorded in patient diaries over three consecutive chemotherapy cycles. Additionally, physicians report their efficacy assessments of NEPA online, using an eCRF.

Results

At the cut-off date November 11, 2017, 2427 patients had been enrolled in the study. For the interim analysis 986 breast cancer patients were evaluated who had been fully documented in the eCRF at the cut-off date.

95% had an ECOG performance status of 0 or 1. 51% received adjuvant, 44% neoadjuvant, and 5% palliative chemotherapy. 80% of patients received HEC, mostly (79%) anthracycline/cyclophosphamide (AC) combinations. Of the women receiving MEC, the majority were treated with carboplatin-based regimens (9%). 7% of patients received other MEC regimens.

81.4-82.8 % of patients reported CR in cycles 1-3 and more than 93% of patients reported no emesis during the 3 treatment cycles covered in the patient diaries. No significant nausea was reported by 62.7-64.2% of patients.

Physicians rated the efficacy of the antiemetic prophylaxis with NEPA using the 4 categories very good, good, satisfactory, and poor. In cycles 1 and 2, more than 89% of physicians rated the efficacy of NEPA very good or good. In cycle 3, 90.6% rated it very good or good. In addition to reporting CR, nausea and emesis episodes in their patient diaries, patients used the same 4 categories to assess the efficacy of NEPA at the end of each treatment cycle. Efficacy assessments of physicians and patients were very similar, with 87% of patients choosing very good or good in cycle 1 compared to 89% of physicians.

NEPA was well tolerated. Low-grade constipation (14.9%) and insomnia (8.3%) were the most frequent treatment-related adverse event.

Conclusion

In this real life study, NEPA was effective in the prevention of CINV in the subgroup of breast cancer patients receiving HEC or MEC. The efficacy assessments by patients and physicians were comparable, with approximately 90% good or very good efficacy for 3 consecutive cycles. More than 93% of patients reported no emesis and more than 81% reported CR during the 5 days post-chemotherapy during all 3 cycles. The study is ongoing.

A randomised crossover trial of minimising medical terminology in secondary care correspondence in patients with chronic health conditions: impact on understanding and patient reported outcomes

BACKGROUND

There is little existing research on the role that secondary care letters have in ensuring patient understanding of chronic health conditions.

AIM

To determine whether minimising the use of medical terminology in medical correspondence improved patient understanding and anxiety/depression scores.

METHODS

A single-centre, non-blinded, randomised crossover design assessed health literacy, EQ-5D scores and the impact of the 'translated' letter on the doctor's professionalism, the patient's relationship with their general practitioner (GP) and their perceived impact on chronic disease management. Patients were crossed over between their 'translated' and original letter.

RESULTS

Sixty patients were recruited. Use of a 'translated' letter reduced mean terms not understood from 7.78 to 1.76 (t(58) = 4.706, P < 0.001). Most patients (78.0%) preferred the 'translated' letter, with 69.5% patients perceiving an enhancement in their doctor's professionalism (z = 2.864, P = 0.004), 69.0% reporting a positive influence on relationship with their GP (z = 2.943, P = 0.003) and 79.7% reporting an increase in perceived ability to manage their chronic health condition with the 'translated' letter (z = 4.601, P < 0.001). There was no effect on EQ-5D depression/anxiety scores.

CONCLUSION

Minimising the use of medical terminology in medical correspondence significantly improved patient understanding and perception of their ability to manage their chronic health condition. Although there was no impact on EQ-5D depression/anxiety scores, overwhelming patient preference for the 'translated' letter indicates a need for minimisation of medical terminology in medical correspondence for patients with chronic health conditions.

Development of a human three-dimensional organotypic skin-melanoma spheroid model for in vitro drug testing

Despite remarkable efforts, metastatic melanoma (MM) still presents with significant mortality. Recently, mono-chemotherapies are increasingly replenished by more cancer-specific combination therapies involving death ligands and drugs interfering with cell signaling. Still, MM remains a fatal disease because tumors rapidly develop resistance to novel therapies thereby regaining tumorigenic capacity. Although genetically engineered mouse models for MM have been developed, at present no model is available that reliably mimics the human disease and is suitable for studying mechanisms of therapeutic obstacles including cell death resistance. To improve the increasing requests on new therapeutic alternatives, reliable human screening models are demanded that translate the findings from basic cellular research into clinical applications. By developing an organotypic full skin equivalent, harboring melanoma tumor spheroids of defined sizes we have invented a cell-based model that recapitulates both the 3D organization and multicellular complexity of an organ/tumor in vivo but at the same time accommodates systematic experimental intervention. By extending our previous findings on melanoma cell sensitization toward TRAIL (tumor necrosis factor-related apoptosis-inducing ligand) by co-application of sublethal doses of ultraviolet-B radiation (UVB) or cisplatin, we show significant differences in the therapeutical outcome to exist between regular two-dimensional (2D) and complex in vivo-like 3D models. Of note, while both treatment combinations killed the same cancer cell lines in 2D culture, skin equivalent-embedded melanoma spheroids are potently killed by TRAIL+cisplatin treatment but remain almost unaffected by the TRAIL+UVB combination. Consequently, we have established an organotypic human skin-melanoma model that will facilitate efforts to improve therapeutic outcomes for malignant melanoma by providing a platform for the investigation of cytotoxic treatments and tailored therapies in a more physiological setting.
