POS1171 TRIPLE THE RATE OF EMERGENCY ROOM VISITS AND HOSPITALIZATIONS FOR GOUT AMONG US BLACKS VS WHITES – 2019 NATIONWIDE ANALYSIS

Background

Gout is a highly prevalent inflammatory arthritis with increasing global disease burden in recent years.1,2 Gout prevalence has been reported to be higher among Blacks compared to Whites,3 and that they are less likely to receive allopurinol in outpatient care.4 The potential nationwide impact of these racial disparities on emergency department (ED) visits and hospitalizations is unknown.

Objectives

To examine the contemporary racial disparities in ED visits and hospitalizations with a primary discharge diagnosis of gout in the US (2019).

Methods

We compared ED visits and hospitalizations between Blacks and Whites in the latest data (2019) from the US National Emergency Department Sample (NEDS) and National Inpatient Sample (NIS). We focused on encounters for which the primary diagnosis was gout based on ICD codes (M1A.xx, M10.xx). We calculated annual population rates of ED visits and hospitalizations for gout (per 100,000 US adults) using the 2019 US census adult population (>18 years) according to race.

Results

There were a total of 160,759 ED visits and 9,560 hospitalizations among White and Blacks with a gout diagnosis in the US in 2019. The mean age (58.2 years vs. 56.5 years) and male proportion (78.0% vs. 74.8%) tended to be higher among Whites, while more Blacks tended to live in the South (40.7% vs. 66.5%) and reported a median household income of < $50,000 (30.7% vs. 57.1%). Compared to Whites, Blacks had 2.7- and 3.2-fold higher rates of gout ED visits and hospitalizations, respectively, after adjusting for age, sex, payer, region, and household income (Table 1 & Figure 1). Black women, in particular, had 3.4- and 4.0-fold higher rates of ED visits and hospitalizations compared to White women, while the corresponding rate ratios for men were 2.5 and 2.8, respectively. The mean costs per gout ED visit were similar for Blacks compared to Whites (adjusted difference, -$7.6 [95% CI, -25.4 to 1.0]), while hospitalizations were more costly (adjusted difference, $1,055.3 [95% CI, 553.1 to 1557.5]). The duration of ED visits and hospitalizations was also higher among Blacks than Whites (adjusted difference of 0.41 days [95% CI, 0.19 to 0.63] and 0.59 days [95% CI, 0.25 to 0.94], respectively).

*Adjusted for age and sex for all, adjusted for age for sex-specific rate ratios

**Adjusted for age, sex, payment, region, and household income

Conclusion

These latest national data indicate that ED visits and hospitalization due to gout are both 3 times higher among Blacks than Whites; this disparity was particularly prominent among women with gout. Higher risk of developing gout3 and suboptimal care4 both translate to these avoidable costly healthcare utilizations, calling for improved primary prevention and gout care.

Short term outcome of patients attending a renal-immunology clinic in central India

Background:

Glomerular diseases (GDs) and other renal immunologic diseases are an important cause of morbidity and mortality. Providing a single point of service in collaboration with various specialists at a renal immunology clinic for such patients is not novel, but outcomes have not been reported. Here, we report the short-term outcome of Indian patients attending our clinic.

Methods:

This single-center prospective cohort study enrolled biopsy-proven immunologically-mediated adults with renal diseases between April 2018 and December 2019, and followed them for six months. The primary end point for the analysis was an incidence of end-stage renal disease (ESRD) or loss of >50% estimated glomerular filtration rate (eGFR) and patient survival at six months. Secondary endpoints were the rate of complete or partial remission, and impact of demographic factors.

Results:

Ninety two patients underwent renal biopsy for suspected immunological renal diseases. Fourteen (15.2%) cases were excluded for nonimmune etiologies, whereas 78 (84.7%) confirmed cases of immune etiology were included. Most common primary GD (n = 51) (93.5%) was membranous nephropathy (n = 20) (25.6%), whereas lupus nephritis was the most common (n = 8) (29.6%) secondary GD. Overall, 10 (12.8%) patients reached renal endpoint of ESRD or >50% fall in eGFR. Focal segmental glomerulosclerosis (FSGS) (27%) patients had worst renal outcome. Patient survival was 94.8%. Thirty patients (38.4%) achieved complete, whereas 24 each (30.7%) achieved partial remission and remained resistant to disease specific therapies, respectively. Univariate analysis identified hypertension, severity of hypertension, and resistance to achieve proteinuria remission as significantly associated (P < 0.001) factors with poor renal outcome.

Conclusions:

The present study shows that short term renal outcome of Indian patients with renal immune diseases remains poor. FSGS remains the GD with the worst renal outcome. Hypertension, its severity, failure to achieve proteinuria remission were significantly associated with poor renal outcomes.

177 Broad Ligament Hernia: Two Contrasting Ways to a Common Goal – Two Case Reports

Introduction

Broad ligament hernia (BLH) is a rare but potentially life-threatening condition. One of the two cases described here is the only reported case of BLH in recent literature, where marsupialization was done. These two case reports comprise the only reported side-by-side pictorial comparison of the two laparoscopic surgical therapeutic options for BLH.

Presentation of cases

Both patients presented with classical symptoms and signs of acute intestinal obstruction. Imaging confirmed obstructed left BLH in case 2 and indicated a complete small bowel obstruction in case 1. Both cases were successfully managed laparoscopically. Both patients had an uneventful immediate postoperative recovery and have not had recurrence over a mean follow-up period of 34.5 months.

Discussion

BLH is rare among all types of internal herniae. It accounts for only 4% of internal herniae and is a difficult condition to diagnose. The advent of computed tomography has increased the chances of accurate preoperative diagnosis.

Conclusion

BLH can be successfully managed by minimally invasive surgery, even in the acute setting. When tightly entrapped bowel is unyielding; it is better not to risk injury to it by aggressive attempts at its reduction. It is safer to attempt widening of the defect into which it is entrapped, whenever feasible.

Using Ethereum Smart Contracts to Store and Share COVID-19 Patient Data

Introduction

The emergence and rapid spread of the coronavirus disease 2019 (COVID-19) pandemic have revealed the limitations in current healthcare systems to handle patient records securely and transparently, and novel protocols are required to address these shortcomings. An attractive option is the use of Ethereum smart contracts to secure the storage of medical records and concomitant data logs. Ethereum is an open-source platform that can be used to construct smart contracts, which are collections of code that allow transactions under certain parameters and are self-executable.

Methods

The present study developed a proof-of-concept smart contract that stores COVID-19 patient data such as the patient identifier (ID), variant, chest CT grade, and significant comorbidities. A sample, fictitious patient data for the purpose of testing was configured to a private network. A smart contract was created in the Ethereum state and tested by measuring the time to insert and query patient data.

Results

Testing with a private, Proof of Authority (PoA) network required only 191 milliseconds and 890 MB of memory per insertion to insert 50 records while inserting 350 records required 674 milliseconds and similar memory per insertion, as memory per insertion was nearly constant with the increasing number of records inserted. Retrieving required 912 MB for a query involving all three fields and no wildcards in a 350-record database. Only 883 MB was needed to procure a similar observation from a 50-record database.

Conclusion

This study exemplifies the use of smart contracts for efficient retrieval/insertion of COVID-19 patient data and provides a case use of secure and efficient data logging for sensitive COVID-19 data.

Plasma cell rich acute rejection: Risk factors, treatment and outcomes

Plasma cell-rich rejection is a rare and poorly defined entity. Its treatment is not clearly defined and has universally poor prognosis. More data should be published from various transplant centers around the world to identify the treatment that has the best outcomes and to formulate treatment guidelines for these cases. It is a retrospective analysis of kidney biopsies form 2008 to 2018. Four hundred biopsied were screened and 55 were found to have features of rejection and among them, 13 had plasma cell-rich rejection. Data of treatment given and the graft survival outcomes in these cases were retrieved by medical records. One patient had complete recovery, three had graft loss and the remaining nine had permanent decline in glomerular filtration rate. Decrease in immunosuppression and presence of infection are risk factors for plasma cell-rich acute rejection (PCAR). It can be acute cell-mediated rejection (ACR)/antibody-mediated rejection (AMR)/ACR+AMR. Resistant rejection, ACR+AMR, C4d positivity, and severe interstitial inflammation are poor prognostic factors. Overzealous decrease in immunosuppression should not be done. Management of immunosuppression during infection is most critical for the development of PCAR. Bortezomib is emerging as a therapeutic modality for the treatment of PCAR.

Zanamivir aqueous solution in severe influenza: A global Compassionate Use Program, 2009-2019

BACKGROUND

Zanamivir is a neuraminidase inhibitor effective against influenza A and B viruses. In 2009, GlaxoSmithKline (GSK) began clinical development of intravenous (IV) zanamivir and initiated a global Compassionate Use Program (CUP) in response to the evolving H1N1 global pandemic. The goal of the CUP was to provide zanamivir to critically ill patients with limited treatment options.

METHODS

Zanamivir was administered to patients with suspected or confirmed influenza infection who were not suitable for other approved antiviral treatments. Reporting of serious adverse events (SAEs) was mandatory and recorded in the GSK safety database. A master summary tracking sheet captured requests and patient characteristics. A case report form was available for detailing medical conditions, dosing, treatment duration, and clinical outcomes.

RESULTS

In total, 4,033 requests were made for zanamivir treatment of hospitalized patients from 38 countries between 2009 and 2019; ≥95% patients received zanamivir via the IV route. Europe had the highest number of requests (n = 3,051) followed by North America (n = 713). At least 20 patients were aged ≤6 months, of whom 12 were born prematurely. The GSK safety database included 466 patients with ≥1 SAE, of whom 374 (80%) had a fatal outcome. Drug-related SAEs were reported in 41 (11%) patients, including hepatic failure (n = 6 [2%]) and acute kidney injury (n = 5 [1%)].

CONCLUSIONS

The CUP facilitated global access to zanamivir prior to product approval. No new safety concerns were identified in the CUP compared with IV zanamivir clinical studies.

Post-cricoid and Upper Oesophagus Cancers Treated with Organ Preservation Using Intensity-modulated Image-guided Radiotherapy: a Phase II Prospective Study of Outcomes, Toxicity and Quality of Life

AIMS

To prospectively examine the outcomes, toxicity and quality of life (QoL) of patients with post-cricoid and upper oesophagus (PCUE) cancers treated with an organ-preservation approach of (chemo)-radiotherapy using intensity-modulated image-guided radiotherapy (IM-IGRT).

MATERIALS AND METHODS

This phase II prospective study was conducted at a tertiary cancer centre from February 2017 to January 2020. Forty patients with squamous cell carcinoma of PCUE of stage T1-3, N0-2, M0 were accrued. Gross exolaryngeal extension/dysfunctional larynx were major exclusion criteria. Patients received 63-66 Gy in once-daily fractions using volumetric modulated arc therapy with daily IGRT. Outcome measures included disease-related outcomes, patterns of failure, Radiation Therapy Oncology Group toxicities, feeding tube dependency and QoL.

RESULTS

The median follow-up was 22 months. Twenty-six (87.5%) patients had locoregionally advanced disease and 34 (85%) patients received (chemo)-radiotherapy. A complete response was observed in 26 (65%) patients. The 2-year locoregional control, event-free survival and cause-specific survival were 59.6%, 40.2% and 44.8%, respectively. The volume of primary tumour (GTVPvol) exceeding 28 cm³ had inferior overall survival (P = 0.005) on univariate analysis. Multivariable analysis showed GTVPvol and positron emission tomography-computed tomography maximum standardised uptake value to be independently predictive for event-free and overall survival. A feeding tube requirement at presentation was seen in 11 (27.5%) patients, whereas long-term feeding tube dependency at 6 months was seen in 10 (37%) patients. For QoL, a statistical improvement in pain, appetite loss and swallowing was observed over time.

CONCLUSION

Although the outcomes of PCUE cancers remain dismal, the use of state of the art diagnostic modalities, careful case selection and modern radiotherapy techniques improved outcomes as compared with before in this exclusive analysis of PCUE cancers.

Non-linear and non-additive associations between the pregnancy metabolome and birthweight

BACKGROUND

Birthweight is an indicator of fetal growth and environmental-related alterations of birthweight have been linked with multiple disorders and conditions progressing into adulthood. Although a few studies have assessed the association between birthweight and the totality of exogenous exposures and their downstream molecular responses in maternal urine and cord blood; no prior research has considered a) the maternal serum prenatal metabolome, which is enriched for hormones, and b) non-linear and synergistic associations among exposures.

METHODS

We measured the maternal serum metabolome during pregnancy using an untargeted metabolomics approach and birthweight for gestational age (BWGA) z-score in 410 mother-child dyads enrolled in the PRogramming of Intergenerational Stress Mechanisms (PRISM) cohort. We leveraged a Bayesian factor analysis for interaction to select the most important metabolites associated with BWGA z-score and to evaluate their linear, non-linear and non-additive associations. We also assessed the primary biological functions of the identified proteins using the MetaboAnalyst, a centralized repository of curated functional information. We compared our findings with those of a traditional metabolite-wide association study (MWAS) in which metabolites are individually associated with BWGA z-score.

RESULTS

Among 1110 metabolites, 46 showed evidence of U-shape associations with BWGA z-score. Most of the identified metabolites (85%) were lipids primarily enriched for pathways central to energy production, immune function, and androgen and estrogen metabolism, which are essential for pregnancy and parturition processes. Metabolites within the same class, i.e. steroids and phospholipids, showed synergistic relationships with each other.

CONCLUSIONS

Our results support that the aspects of the maternal metabolome during pregnancy contribute linearly, non-linearly and synergistically to variation in newborn birthweight.

Impact of Adjuvant Treatment in pN3 Penile Cancer

AIMS

Due to the lack of high-quality evidence and consensus on adjuvant treatment for locoregionally advanced penile cancer, we reviewed the outcomes of pN3 patients to determine the suitable adjuvant treatment options.

PATIENTS AND METHODS

All consecutive pN3 penile cancer patients treated at our institution between January 2010 and December 2018 were reviewed to assess the impact of demographical, pathological and treatment factors on disease-free survival (DFS) and overall survival. The DFS and overall survival were estimated using the Kaplan-Meier method and association was tested using the Cox regression model (two-sided test with P < 0.05 considered significant).

RESULTS

Of 128 patients, 31 (24%) had pelvic nodal involvement. Twenty-six patients (20.3%) received no adjuvant treatment, 40 (31.3%) received single modality adjuvant treatment and 62 (48.4%) received multimodality adjuvant treatment (a combination of chemotherapy and radiotherapy). At a median follow-up of 22 months, the DFS and overall survival were 55.4 and 62%, respectively. The best DFS and overall survival was noted with chemotherapy followed by concurrent chemoradiation (C-CTRT; 93% each). On multivariate analysis, both DFS and overall survival were worse with pelvic node involvement (2.2 [1.3-4], P = 0.027 and 2.2 [1.3-4], P = 0.027, respectively) and better with any adjuvant treatment (single modality: 3 [1.5-5.5], P < 0.001; multimodality: 3.1 [1.6-6], P < 0.001). C-CTRT was associated with improved DFS over chemotherapy alone (0.17 [0.4-0.78], P = 0.02) but not over radiotherapy alone (0.35 [0.07-1.6], P = 0.19). In patients with no pelvic nodes involved, chemotherapy and radiotherapy as single modalities were associated with similar DFS and overall survival. In patients with pelvic nodes, multimodality treatment was associated with better DFS than single modality treatment (0.3 [0.1-1], P = 0.05).

CONCLUSION

pN3 penile cancer is a diverse prognostic group with poorer outcomes associated with pelvic nodes. Single modality adjuvant treatment may be adequate in inguinal nodes with extranodal extension, but multimodality treatment should be given in patients with pelvic nodal involvement.

Insufficient Iodine Level in Urine among Children of a Secondary School: A Descriptive Cross-sectional Study

Introduction:

Iodine deficiency disorders are common endocrinopathies in Nepal. Children are at risk for iodine deficiency disorders. Irreversible mental retardation and brain damage in children are the devastating disorders lead by iodine deficiency. Therefore, the main objective of the study was to find out the prevalence of insufficient iodine level among the children of a secondary school.

Methods:

This descriptive cross-sectional study was conducted in urine from April 2019 to July 2019 after obtaining ethical approval from Nepal Health Research Council (Registration number: 802/2018). Forty-six urine samples were collected from school children for iodine estimation. Convenience sampling was done. Data were entered into Statistical Package for the Social Science version 21 and descriptive analyses were done. Point estimate at 95% confidence interval was calculated along with frequency and proportion for binary data.

Results:

Among the 46 students, majority 36 (78.30%) (95% Confidence Interval= 66.30-90.21) of the school children had insufficient urine iodine level. Among 36 salt samples collected from school children with low urine iodine level, 8 (22.2%) salt samples had iodine less than 15ppm.

Conclusions:

Iodine estimation revealed a very high percentage of urine samples containing insufficient levels of iodine is similar as compared to studies done in similar settings. Hence, the school children were at risk of iodine deficiency disorders. Iodine deficiency disorders prevention programs should be priority intervention based on available evidence.

The impact of psychiatric diagnoses on two-year outcomes in patients with ventricular assist devices

Background

A multi-specialty approach is required during patient selection for left ventricular assist device (LVAD) implantation. In addition to a comprehensive medical evaluation, patients undergo an extensive psychiatric work up to ensure their candidacy when pursuing durable support devices. We aim to analyze the impact of psychiatric illnesses on 2-year outcomes after VAD implantation.

Methods

This study was a single center, retrospective analysis of 263 patients who underwent durable LVAD implantation between 2015 and 2017. All patients were evaluated by a single specialist during their work up for LVAD implantation. Patients who had a pre-existing diagnosis defined by criteria outlined in Diagnostic and Statistical Manual of Mental Disorders (DSM-5) were assigned to the History of Psychiatric Diagnosis group. Statistical analysis was performed using Chi-Square and Student's t-tests, wherein p&lt;0.05 was considered statistically significant.

Results

Of the 263 patients, 68 patients were found to have a history of psychiatric illness compared to 195 who had no previous diagnosis. Of those with a psychiatric history, 30.8% had Depression, 1.5% had Bipolar disorder, 22.1% had Anxiety, 1.5% had PTSD, and 16.2% had more than one diagnosis. 19.5% of patients with no history went on to be transplanted compared to 22.1% of patients with a psychiatric history (p=0.65). No significant difference was found between length of stay, days to readmission, 30-day survival, and 2-year survival. Patients without a psychiatric history were found to have fewer number of readmissions over 2 years (p&lt;0.01) (See Table). No significant difference was seen in complications including driveline infections, bacteremia, cerebrovascular accidents, pump thromboses, pump hemolysis, or major bleeding events (See Table).

Conclusion

Psychosocial characteristics play a significant role in determining a patient's candidacy for LVAD implantation. Although patients with a history of psychiatric illness were found to have a greater number of readmissions, this did not correlate to poorer outcomes or increased morbidity and mortality over 2 years. This study highlights the importance of taking a multi-faceted approach when determining patient eligibility for mechanical support devices. Future studies with larger population models should be conducted.

Mortality and long-term outcomes of palliative inotropes in ischemic and non-ischemic cardiomyopathy

Background

Palliative inotropes are frequently utilized for symptom management in patients with end stage heart failure who are unable to undergo durable advanced heart failure therapies. With the advent of improved medical management and early intervention, palliative inotropes may allow for improved patient outcomes than seen previously. In this study, we aim to investigate the survival and outcomes of palliative inotrope therapy and its impacts on ischemic versus non-ischemic cardiomyopathy.

Methods

We retrospectively analyzed 220 patients with American Heart Association Stage D heart failure who were discharged with palliative inotrope therapy after January 1, 2010. Patients who underwent mechanical circulatory support (MCS) or those who underwent heart transplant were excluded. Those with a history of coronary artery disease, myocardial infarction, history of percutaneous intervention, or coronary artery bypass grafting were assigned to ischemic cardiomyopathy (ICM), while patients without these findings were assigned to non-ischemic cardiomyopathy (NICM). Statistical analysis was completed using Chi-Square and Student's t-tests, wherein p&lt;0.05 was considered statistically significant.

Results

Of the 220 patients, 87 had NICM as opposed to 133 with ICM. Mean age was found to be higher among patients with ICM (70 [62–79]) compared to NICM (65 [55–72], p-value &lt;0.01). No significant difference was seen in total days on inotrope therapy (p=0.6). While more patients in both groups were placed on milrinone as opposed to dobutamine, there was no difference between patients with ischemic and NICM (p=0.66 and 0.51 respectively). Although a greater number of patients with NICM had been lost to follow up, admitted to hospice, or expired at 2 years (p&lt;0.01), survival at 3 months, 1 year, and 2 years showed no difference between both groups. No difference was seen in number of hospitalizations or clinic visits in one year. Both groups had similar complication rates with intravenous-access related PICC line infections and new arrhythmias. (See Table).

Conclusion

Despite more frequent use of durable mechanical support devices, many patients who are deemed unsuitable for invasive measures are treated with palliative inotrope therapy. We have found that there is no significant difference in survival, complications, and outcomes of patients on palliative inotropes among ischemic and NICM. These findings show the versatility of palliative inotrope therapy in end stage heart failure. Further studies with larger populations need to be evaluated.

Cerebrovascular accidents in patients supported with veno-arterial extra-corporeal membrane oxygenation- is duration of support important?

Purpose of study

Veno-Arterial Extra-corporeal Membrane Oxygenation (VA-ECMO) is indicated for refractory cardiac and/or respiratory failure. Adverse events remain considerable despite best practices. We specifically aimed to understand risk factors associated with cerebrovascular accidents (CVA) in patients who underwent VA-ECMO support.

Methods

We retrospectively assessed all VA-ECMO patients from 2007 to 2019 at our institution. We identified those who experienced a CVA while supported by VA-ECMO. Patients with the primary event (CVA) were matched to controls (no CVA) based on age and sex. Comparisons were made between groups using McNemar's, Mantel-Haenszel, and Wilcoxon Signed-Rank tests where appropriate.

Results

Of the 278 VA-ECMO patients in the registry, 32 patients who experienced a CVA were identified; 24 (8.6%) ischemic and 8 (2.9%) hemorrhagic. Median age was 59.5 years (inter-quartile range: 49–65 years) and 75% of patients were males. Hypertension, diabetes, CAD and CHF were common co-morbidities (Table 1). Cardiogenic shock was the most common indication for VA-ECMO support in both cohorts, 75% in cases and 71.9% in controls. Cannulation strategies were identified as central or peripheral. There was a significant association of duration of VA-ECMO support with incidence of CVA, with a p-value of 0.03. Regression analysis showed a trend of increased risk of CVA by 4% for each additional day on VA-ECMO, however, this was not statistically significant (Odds ratio: 1.04; confidence interval 1.00–1.08). Most common outcome was death followed by decannulation to recovery and bridge to LVAD.

Conclusion

Ischemic and hemorrhagic CVAs are not uncommon during VA-ECMO support. Our case control study shows an association of duration of VA-ECMO support with incidence of CVA. This underscores the importance of timely assessment and weaning or bridging of VA-ECMO patients to their next management step.
