This work grew from an interest in understanding how private data are used for health system governance in low-income and middle-income countries (LMICs).
Objective
We conducted a scoping review to understand how the public sector collects routine data from the private health sector and uses it for governance purposes. The private health sector was defined to include both formal and informal, for-profit or non-profit, actors delivering healthcare services.

Findings
We identified 4014 individual English language studies published between 2010 and 2021. We reviewed titles and abstracts of all, with 50% reviewed by two authors to ensure a common application of inclusion criteria. 89 studies were selected for review in full; following this, 26 articles were included in the final selection as they directly report on the use of routine private sector data for governance in LMICs. Only English language studies were included, limiting the scope of possible conclusions.

Results
Data were most commonly collected by the Ministry of Health or a subministerial office, with extraction from District Health Information System 2 specifically cited for three studies. 16 studies collected data on infrastructure and distribution, 15 on service delivery, 12 on health financing, 7 on pharmaceuticals and other consumables, 4 on health workforce, 4 on quality of care and 4 on epidemic surveillance.

Conclusion
The studies identified provide examples of the public sector’s capacity to collect and use data routinely collected from the private sector to perform essential governance functions. The paucity of studies identified is an indication that more attention is needed to ensure that this key area of health system governance is undertaken and that lessons learnt are shared. This review provides insights to understanding private sector health data collection and use for governance in LMICs, and for guiding activities to assess and improve this according to country context and capacity.

Objective
To investigate the effects of in vitro fertilisation (IVF) and intracytoplasmic sperm injection (ICSI) on the clinical outcomes of non-male factor patients aged >35 with three or fewer oocytes retrieved.

Design
Retrospective cohort study.

Setting
Reproductive centre of a university-affiliated hospital in China.

Participants
547 women with non-male factor infertility who underwent assisted reproductive technology (ART) treatment with three or fewer oocytes retrieved were identified from June 2019 to May 2022. Of these 547 patients, 334 were treated with IVF and 213 with ICSI.

Outcome measures
The primary outcomes were normal fertilisation rate, live birth rate per transfer and cumulative live birth rate per retrieval.

Results
The baseline characteristics were comparable between the two groups, except for the proportion of primary infertility, which was higher in the ICSI group (17.66% vs 32.86%, p=0.000). Compared with the IVF group, the ICSI group showed higher normal fertilisation rate and lower cycle cancellation rate (65.99% vs 76.56%, p=0.002; 33.53% vs 24.41%, p=0.023). However, no significant differences were found in clinical pregnancy rate per transfer (23.86% vs 18.92%, p=0.545), miscarriage rate per fresh embryo transfer (19.05% vs 28.57%, p=0.595), live birth rate per transfer (17.05% vs 13.51%, p=0.623), cumulative clinical pregnancy rate per retrieval (12.87% vs 11.27%, p=0.576) and cumulative live birth rate per retrieval (9.28% vs 6.57%, p=0.261) between the two groups (p >0.05).

Conclusions
In non-male factor ART cycles, ICSI was not associated with improved pregnancy outcomes in older women with a low number of oocytes retrieved. Routine use of ICSI is not recommended in older women who are infertile due to non-male factors.

Pain is one of the most debilitating symptoms of cancer, substantially diminishing one’s quality of life. The level of pain experienced is eventually determined by the pain coping strategies adopted by patients individually. The awareness of the ‘self-coping methods of pain’ of individual patients would be beneficial for the multidisciplinary pain team to consider such methods when planning future interventions to manage pain.
Objectives
This study explores the pain perception and coping strategies used by patients with cancer pain in Sri Lanka.

Design
A descriptive qualitative study.

Setting
Pain management unit, Apeksha Hospital, Maharagama, Sri Lanka.

Participants
The study was conducted among purposively selected patients with cancer and registered at the pain management unit. 21 semi-structured interviews were conducted until data saturation. Data were analysed using Graneheim and Lundman’s content analysis method.

Results
Most participants were between 51 and 60 years old and identified as Sinhalese Buddhists. The study’s findings revealed two subthemes under ‘Understanding pain’, namely ‘Physical and emotional impact’ and ‘Cultural and spiritual interpretations’, and five subthemes under ‘Coping strategies for living with pain’, namely ‘Medication and self-control’, ‘Seeking spiritual support’, ‘Receiving social support’, ‘Exploring alternative treatments’ and ‘Adapting daily life’.

Conclusion
Coping strategies were adopted especially in achieving essential life aspirations and participating in preferred activities. Goals or activities were often adjusted to fall within their health limits. Acceptance and progress in life were considered more important than pain control. We recommend giving due consideration to the ‘self-coping strategies’ of individual patients in designing interventions to mitigate cancer pain.

Objectives
Optimising postoperative pain following knee replacement is important for patients, healthcare professionals and healthcare funders. Adductor canal blocks (ACB) are widely used but there is uncertainty about their efficacy when combined with local infiltration analgesia (LIA) compared with either LIA or ACB alone.

Design
A systematic review and meta-analyses of randomised controlled. The primary outcome was pain over the first 72 hours. Secondary outcomes included morphine use, range of movement, distance walked, length of hospital stay, health economic outcomes and reported adverse events.

Data sources
MEDLINE, Embase, EB Health – KSR Evidence, Cochrane Central Register of Controlled Trials, CINAHL, International HTA database, ClinicalTrials.gov and the International Clinical Trials Registry Platform (WHO) were searched up to June 2023.

Eligibility criteria
Randomised controlled trials involving patients undergoing primary total knee replacement comparing LIA combined with ACB to either LIA or ACB alone.

Data extraction and synthesis
All eligible studies were data extracted independently by two reviewers. Studies were pooled for each outcome at each timepoint in a random effects meta-analysis.

Results
We identified 13 completed studies including 1154 participants. 12 studies compared LIA vs combination and 5 compared ACB vs combination. We identified that participants receiving the combination had lower pain scores at rest at 24 hours compared with LIA alone (SMD 0.42, 95% CI 0.20 to 0.64) or ACB alone (SMD 0.63, 95% CI 0.42 to 0.83). Pain on movement at 24 hours was also lower for patients with combination vs LIA alone (SMD 0.37, 95% CI 0.01 to 0.73) or ACB alone (SMD 0.81, 95% CI 0.35 to 1.26). We also identified that patients on combination used less morphine than on LIA alone (MD 1.06, 95% CI –0.09 to 2.20) or ACB alone (MD 5.94, 95% CI –2.41 to 14.29). The same was seen with range of motion at 24 hours with combination having a larger improvement than LIA alone (MD –5.19, 95% CI –5.55 to –4.83) or ACB alone (MD –3.80, 95% CI –4.37 to –3.23). These findings were consistent across all time points; however, there were no studies deemed to be at a low risk of bias.

Conclusions
Further well-designed and conducted randomised controlled trials are needed to confirm if a combination of LIA and ACB is superior to either option alone for patients undergoing primary total knee arthroplasty.

Circulation, Volume 150, Issue Suppl_1, Page A4141438-A4141438, November 12, 2024. Background:Catheter ablation is a well-established treatment for atrial fibrillation (AF). Left atrial low-voltage areas (LVAs) is associated with atrial remodeling following the progression of atrial cardiomyopathy, and poor rhythm outcome after catheter ablation. However, the predictors of LVAs presence have not been fully elucidated in different age groups.Purpose:The purpose of this study was to investigate predictors of the prevalence of LVAs in different age groups.Methods:1,488 (age, 69 ± 10 years; female, 501 [34%]) consecutive patients who underwent initial ablation were included. Age groups were divided into three groups, namely

Circulation, Volume 150, Issue Suppl_1, Page A4123637-A4123637, November 12, 2024. Background:Invasive coronary reactivity testing (CRT) is the gold standard for comprehensive assessment of coronary endothelial and microvascular dysfunction in patients with angina and non-obstructive CAD (ANOCA). Non-invasive imaging modalities (PET and CMR) have emerged as potential alternatives. However, due to the inability to systemically administer acetylcholine, patients with normal coronary flow reserve (CFR) but abnormal endothelial function on invasive Ach testing are systemically missed on non-invasive testing. We aimed to assess the prevalence of coronary endothelial dysfunction in ANOCA patients with normal CFR.Methods:Consecutive patients undergoing CRT at our institution were included. Those with normal adenosine-based CFR ( >2.5), were further stratified as having normal coronary endothelial function (NEF, 50% increase in coronary blood flow in response to ACh) vs abnormal endothelial function (AEF, >20% epicardial coronary diameter constriction and/or

Circulation, Volume 150, Issue Suppl_1, Page A4144554-A4144554, November 12, 2024. INTRODUCTION:Coronary CT angiography (CCTA) is a powerful noninvasive tool for identifying high-risk plaque, such as low-density non-calcified plaque (LD-NCP). Though, the optimal treatment of patients with LD-NCP remains unclear. This study explored the association of revascularization in the setting of LD-NCP with the occurrence of acute coronary syndrome (ACS).Methods:This was a post-hoc analysis of the ICONIC study. A subset of 234 patients that underwent CCTA with subsequent ACS were matched to 234 control patients who also underwent CCTA but did not have ACS during follow-up. Patients were also followed for occurrence of revascularization, either coronary artery bypass graft or percutaneous coronary intervention. Atherosclerosis imaging-enabled quantitative CT (AI-QCT) was used to measure diameter stenosis, and LD-NCP, non-calcified plaque, and calcified plaque volumes from each CCTA. LD-NCP was defined as plaque with -190 to 30 Hounsfield Units. Patients were stratified based on the presence of LD-NCP. Subgroup analysis was conducted to compare the occurrence of ACS with the rate of revascularization. Kaplan-Meier survival curves and extended Cox regression analysis were used to evaluate the effect size of revascularization and LD-NCP on occurrence of ACS.Results:AI-QCT was completed in 448/468 subjects (follow-up time [MEAN±SD] 2.44±2.48 years). The median of LD-NCP was 1.2 mm3for patients with >0 mm3LD-NCP. There were 85 patients with LD-NCP >1.2 mm3and 363 patients with LD-NCP ≤1.2 mm3. In patients with LD-NCP >1.2 mm3, the rate of revascularization in patients with and without ACS was 3/52 (5.8%) versus 14/33 (42.4%) (p1.2 mm3and revascularization were less likely to have ACS during follow-up (adjusted HR: 0.20 [0.07, 0.61]; p=0.005). Additionally, patients with LD-NCP >1.2 mm3who did not undergo revascularization were more likely to have ACS (adjusted HR: 1.47 [1.03, 2.12]; p=0.036). Hazard ratios were adjusted for diameter stenosis, and non-calcified and calcified plaque volume. Time-dependent coefficients were included for diameter stenosis.Conclusion:Revascularization of patients with LD-NCP >1.2 mm3identified on CCTA with AI-QCT was associated with less risk for ACS.

Circulation, Volume 150, Issue Suppl_1, Page A4140117-A4140117, November 12, 2024. Background:Catheter ablation is a most common treatment for atrial fibrillation (AF), but rhythm outcome after AF ablation in long-standing persistent atrial fibrillation (LS-PerAF) is still poor. Left atrial low-voltage areas (LVAs) is associated with poor rhythm outcome after catheter ablation. However, the predictors of LVAs presence have not been fully elucidated in patients with LS-PerAF.Purpose:The purpose of this study was to establish a novel predictive score for the prevalence of LVAs in patients with LS-PerAF ablation.Methods:In total, 109 consecutive patients who underwent initial ablation for LS-PerAF were included. LS-PerAF was defined as AF whose duration was more than 1 year. LVA was defined as areas with bipolar peak-to-peak voltage of < 0.50mV. A clinical risk score was obtained as the total number of independent predictors analyzed by multivariate logistic regression analysis. AF recurrence after the catheter ablation was followed for 24 months.Results:Of 109 patients with LS-PerAF, LVAs existed in 26 (24%) patients. A novel predictive score, named DESK score, consisted of diabetes mellitus (odds ratio [OR] 3.7, [95% confidence interval {CI} 2.2–11], p = 0.02), age ≥ 70 years (OR 3.8, [95% CI 1.4-10], p = 0.007), female sex (3.0 [95% CI 1.04-8.4], p = 0.04), AF duration ≥ 3.7 years (44 months) (OR 3.7, [95% CI 1.3-11], p =0.02). LVAs were more frequently found in patients with a higher DESK score (OR, 3.5 [95% CI, 1.9–6.5], p < 0.001) (Figure 1A). On receiver operating characteristic curve analysis, DESK score was a moderate predictor of LVAs presence (area under the curve, 0.750; Figure 1B). The optimal cut-off of DESK score was 3 points, corresponding to a 38.5% sensitivity, 97.6% specificity, and 83.5% predictive accuracy. Freedom from AF recurrence was significantly lower in patients with DESK score ≥ 3 than in those with DESK score < 3 (10.4% vs. 43.5%, p = 0.008).Conclusions:In patients who underwent LS-PerAF ablation, the DESK score correlated with the prevalence of LVAs, and associated with poor rhythm outcome.

Circulation, Volume 150, Issue Suppl_1, Page A4145822-A4145822, November 12, 2024. Introduction:Anomalous Left Coronary Artery Arising from the Pulmonary Artery (ALCAPA), also known as Bland-White-Garland syndrome, is a rare congenital anomaly(incidence:1 in 300,000 live births) typically presenting during infancy. Adult presentations are even rarer due to a high mortality rate of nearly 90% in the first year of life without surgical intervention. This report examines an adult patient with exercise-induced chest pain who received a delayed diagnosis of ALCAPA via multimodal imaging.Case Summary:A 21-year-old male presented to the emergency department(ED) with severe retrosternal chest pain radiating to both shoulders and arms, which began during exercise 30 minutes prior. He had a history of similar, milder episodes during exercise, previously treated as musculoskeletal pain and gastroesophageal reflux disease in the ED. His medical, social, and family histories were unremarkable. Physical examination revealed a soft, continuous murmur along the left sternal border. During this visit, An EKG done showed sinus tachycardia at 110 bpm and deep T-wave inversions in the anterolateral leads, a dynamic ST-T changes from his baseline.Serial Cardiac biomarkers and a lipid profile were within normal ranges. Initially managed for acute coronary syndrome-unstable angina with antithrombotic therapy, beta-blockers, and nitrates, he underwent urgent coronary angiography. This revealed a dilated right coronary artery (RCA) with retrograde flow to the left coronary artery (LCA) into the main pulmonary artery (PA) via collaterals, with no evidence of atherosclerosis (Figure 1).Echocardiography (Figure 2) and coronary CT angiography (Figure 3) confirmed the diagnosis of ALCAPA. The patient underwent successful surgical repair with aortic reimplantation of the LCA and was discharged in good health.Discussion:In adult ALCAPA patients, good collateral circulation may develop; however, myocardial ischemia can occur due to the “coronary steal phenomenon” and poor collateral flow regulation, leading to angina, arrhythmias, and sudden cardiac death. ALCAPA should be considered a differential diagnosis in adults presenting with exercise intolerance, as most sudden cardiac death cases occur by the fourth decade. A high index of clinical suspicion and a multimodality imaging approach is essential for the early diagnosis of this rare coronary anomaly, underscoring the critical role of early surgical intervention in preventing catastrophic, life-threatening events.

Circulation, Volume 150, Issue Suppl_1, Page A4136984-A4136984, November 12, 2024. .Background:Third-degree atrioventricular block (AVB) is the most common manifestation of Anti-Ro antibody associated fetal cardiac disease. Extranodal findings of isolated cardiac echogenicity, valvulitis with insufficiency and AV interval prolongation have been reported but not described in large prospective series.Aims:To report the occurrence and outcomes of extranodal findings in subjects followed prospectively since 2020 in STOP BLOQ (Surveillance and Treatment to Prevent Fetal AV block Likely to Occur Quickly) and the Registry for Neonatal Lupus (RNL).Methods:We reviewed fetal echo reports from pregnant STOP BLOQ and RNL Anti-Ro antibody subjects. Pregnancies with high ( >1000 EU for anti-Ro52 or 60) antibody titers measured in a core research lab underwent surveillance with home fetal heart rate monitoring (FHRM) 3x/day and weekly or bi-weekly fetal echos from 17- 26 gestational weeks. Low titer subjects underwent echo or no surveillance based on local site protocol. We evaluated cardiac function, effusions, cardiac echogenicity and its location, any tricuspid (TV) or mitral (MV) insufficiency trivial or >trivial) and AV conduction times (170 ms)Results:Echo reports were available in 622 prospectively followed pregnancies (376 high (40/376 with a previously affected child) and 246 low-titer pregnancies. All had subjectively normal ventricular function and none had effusions. Seven fetuses, 2 low and 5 high titer at 19 (range 16.7-21.7) weeks demonstrated cardiac echogenicity (n=6), AV or semilunar valve insufficiency (n=2) or AV interval 150-170 ms (n=2) (Table). Subjects 1 and 2, both high titer and treated with prophylactic Plaquenil (400 mg/d before 10 gestational weeks), had prior fetal AVB. Subject #1 had normal AV conduction but MV and TV echogenicity and moderate insufficiency of both valves which resolved in days after IVIG and dexamethasone (dex) treatment, but 3° AVB developed at 19 weeks after dex wean. Subjects 2-7 received no treatment and extranodal findings did not progress to cardiac dysfunction or AVB. During the same time period, 10 high titer subjects developed 2° or 3° AVB.Conclusion:Anti-Ro associated extranodal findings are rare, occurring in 1% of pregnancies overall and in 5% of pregnancies with a previously affected child. Unlike AVB, extranodal findings can occur in low titer pregnancies. The role of treatment for isolated extranodal findings in the absence of cardiac dysfunction is unclear.

Introduction:Despite early mitigation efforts, the opioid pandemic in the United States has persisted and affected many Americans. A public health emergency was declared urging all prescribers to use caution in prescribing opioids. Alternative approaches to postoperative pain management during transvenous cardiac device implants (TCDI) in adults have not been described.Methods:We report a single-center retrospective analysis of 612 consecutive patients that underwent TCDI between January 2021 and January 2024 with ultrasound guided pectoral nerve block (PNB) using liposomal bupivacaine prior to implant for postoperative pain management. Pain scores (0-10) were recorded systematically in the postoperative period, at discharge, and at wound check follow-up. Any need for opioid use in the postoperative period was recorded as well.Results:A total of 612 patients were evaluated, 50% female with a mean age of 71.2 years. All patients received PNB successfully with no device site infection or hematomas. The mean Visualized Analog Scale (VAS) pain scores at 1, 3, and 5 hours after the procedure, at discharge, and at the follow-up visit were 1.93, 1.22, 1.10, 1.05, and 0.13 respectively. During follow-up, no patients required opioids for pain control throughout the entire postoperative period of 14 days.Conclusion:Pectoral nerve block with liposomal bupivacaine can be performed safely preoperatively during TCDI and provides adequate pain control without need for opioid use postoperatively. Further research is needed to assess broad scale implications of this approach to larger patient populations.

However, little is known regarding the safety and effectiveness of a low carbohydrate ketogenic diet (LCKD) in patients with overweight or obesity and HF.Purpose:To examine the safety and effectiveness of a LCKD in patients with overweight or obesity and HF.Methods:A retrospective review from 2006-2024 was conducted of all patients with overweight or obesity and HF who followed a LCKD with clinical oversight for at least one year in a university health system. Changes in metabolic outcomes, echocardiographic measures, and medication use were assessed. Heart failure hospitalization (HFH) rates and rate ratios (RR) and all-cause mortality rates were calculated and stratified by HF classification.Results:A total of 125 patients met inclusion criteria, including 59 patients with HF with reduced ejection fraction (HFrEF) and 66 patients with HF with preserved ejection fraction (HFpEF). Patients lost a median (interquartile range) of 11.2 kg (-19.5, 4.4;p

Circulation, Volume 150, Issue Suppl_1, Page A4141389-A4141389, November 12, 2024. Introduction:Heart failure with preserved ejection fraction (HFpEF) is an increasingly prevalent form of heart failure (HF) in the US today. Our prior work revealed low albumin at first hospitalization for HF exacerbation with underlying HFpEF to be an independent predictor of all-cause mortality in a small cohort of patients. We now sought to confirm our earlier findings across a larger and more diverse patient population.Methods:Seven thousand, eight hundred and forty patients had a first admission to Mayo Clinic for HF exacerbation with an echo-confirmed left ventricular ejection fraction >50% between 2010 and 2020. Patient baseline demographics, co-morbidities, admission laboratory values, echocardiographic parameters, discharge medications, and outcomes were obtained from chart abstraction. To validate our previous model, patients were grouped based on the number of risk factors as previously defined: age >80 years, serum albumin level

Circulation, Volume 150, Issue Suppl_1, Page A4139307-A4139307, November 12, 2024. Introduction:Heart failure (HF) is associated with unique comorbidities and sequelae, which can affect clinical presentation and patient outcomes. This is specifically challenging when patients are evaluated for suspected acute coronary syndrome (ACS). We sought to compare the most important predictors of poor outcomes in patients with and without HF seen in the emergency department (ED) for ACS.Methods:This was a secondary analysis of a prospective observational cohort study of consecutive patients seen for symptoms suggestive of ACS, such as chest pain (CP) and dyspnea, in the EDs of three UPMC-affiliated tertiary care hospitals (NCT04237688, clinicaltrials.gov). Primary outcome was 30-day major adverse cardiac events (MACE), adjudicated by two independent reviewers. Clinical data were collected form charts and we used KNN to impute missing data for features, most of which had less than 12.5% missingness. For features with greater than 12.5% missingness (i.e., BNP, Mg), binary indicators were added to flag missing values. Data were normalized using the Euclidean norm. Two random forest (RF) classifiers were trained using 10-fold cross validation with 71 manually selected features available early in the ED course (i.e., vital signs, labs, past medical history, ECG), and tested on patients with and without known HF. Model performance was evaluated using AUROC, and top features were identified with SHAP values.Results:The sample included 2400 patients (age 59 ± 16 years; 47% female, 41% Black, 15.9% ACS), of whom 438 had HF (age 66 ± 14 years; 45% female, 49% Black, 15.1% ACS). Individuals with HF were more likely to experience MACE (38% vs 23%,p

Circulation, Volume 150, Issue Suppl_1, Page A4140382-A4140382, November 12, 2024. Introduction:Although an estimated 54% of patients with heart failure (HF) and chronic pain report high symptom-associated distress, it is unclear whether pain predicts reduced physical function, cognitive function, independent activities of daily living (IADL) or health-related quality of life (HRQL) over time. The aims were to evaluate baseline pain presence as a predictor of physical function, cognitive function, IADL, and HRQL at baseline, 10 weeks, 4 months, and 8 months after baseline.Methods:In a retrospective longitudinal secondary analysis, data were analyzed from 237 participants with HF enrolled in the Cognitive Intervention to Improve Memory in Heart Failure Patients study. Pain presence was measured with the Health Utilities Index Mark-3 Questionnaire (HUI-3), physical function was measured by the Timed Up and Go (TUG), cognitive function was measured with the Montreal Cognitive Assessment (MoCA), IADL was measured by the Everyday Problems Test (EPT), and HRQL was measured by the Minnesota Living with Heart Failure Questionnaire (LHFQ). Descriptive statistics, independent t-tests, and linear mixed models were used to achieve the aims while controlling for gender.Results:The demographics were mean age 66.31 ± 12.02 years, gender 46% men, 54% women, race 13.5% Black, 85.7% White, 0.8% Other, NYHA class I: 9.7% II: 37.6% III: 52.7%, average LVEF: 48.9%. A total of 160 (67.51%) reported pain.In independent t-tests, patients with pain experienced significantly longer (i.e., worse) TUG scores at all timepoints except 10 weeks, and significantly higher (i.e., worse) LHFQ scores at all timepoints (see Table 1). However, in linear mixed models, pain at baseline did not predict TUG scores (F = 1.239, p = .298), MoCA scores (F = 0.148, p = .931), EPT scores, (F = 0.522, p = .668), or LHFQ scores (F = 0.364, p = .779) over time – see Table 1.Conclusions:Patients with HF and pain experienced significantly worse LHFQ and TUG scores at multiple timepoints. However, pain did not significantly predict cognitive function, physical function, IADL, or HRQL over time. Future prospective studies are needed to examine other outcomes associated with pain in this population and utilize more robust pain instruments.
