Introduction : Obtaining serial head computed tomography (CTH) imaging for patients with spontaneous intracerebral hemorrhage (sICH) is commonly utilized to monitor for hematoma expansion (HE), defined as an increase in ICH volume by 33%. Obtaining recurrent CTH in the ICU setting may burden nursing and transport staff, expose patients to radiation, and inflate healthcare costs. It remains unclear whether utilizing scheduled CTH for sICH patients is more advantageous than targeted CTH, which is prompted by a decline in neurological status. We reviewed clinical factors and imaging studies in patients with and without HE. Methods : This retrospective cohort study conducted over two years identified 171 sICH patients. Patient demographics, clinical and neuroimaging data were recorded (including the reason for repeat imaging). These variables were then compared and analyzed in relation to HE using SPSS version 26, chi‐square tests for categorical variables, and independent‐samples t‐tests were used for continuous variables. Results : Patients were predominantly male (65%), with a mean age of 65±14 years, a median GCS of 14, a median ICH score of 1, and a median ICH volume of 12.1 ccs. Repeat CTH was obtained within 14 hours after the initial imaging on average. Admission blood pressure (BP), BP‐lowering interventions, pre‐admission use of anticoagulant and antiplatelet therapy, GCS on admission, ICH volume, ICH score, and presence of spot signs were similar between the two groups. 15% of total patients (26/171) had HE. In the group that underwent scheduled repeat CTH, only 7% (9 patients) had HE, while the remaining 93% (119 patients) did not. Patients who underwent a second scan following a change in the neurologic assessment included 39% (17 patients) who had HE, compared to 61% (26 patients) that did not. HE detection was significantly lower in patients that underwent scheduled CTH (p < 0.0001). Conclusions : In patients with a stable exam, scheduled head CT only showed HE in 6% of patients; thus, the excess burden, radiation, and costs may not be necessary for these patients. Hematoma expansion is significantly lower in patients who underwent scheduled imaging than those prompted by a decline in neurologic status. However, our sample size is small and additional studies with larger population sizes are required to validate our findings.

The Impact

Background: Intracerebral hemorrhage (ICH) in left ventricular assist device (LVAD) patients is a devastating complication. Hematoma expansion (HE) is associated with poor outcomes in ICH patients, but the impact of HE on LVAD patients is not known. Prevention of HE includes rapid and complete coagulopathy reversal, adding further potential complications in LVAD patients given the inherent risk of hardware thrombosis. We aimed to define the occurrence of HE in the LVAD population and to determine the association between HE and mortality in this population. Methods: We performed a retrospective cohort study of ICH patients with preceding LVAD implantation admitted to Columbia University Irving Medical Center between Jan 2008 and April 2019. Intentionally matched ICH controls without LVADs were identified to compare rate of HE in LVAD and non LVAD patients. ICH volume was measured using ABC/2 method.We defined HE as an increase in hematoma volume of 6 ml or 33% comparing the first and last scan in 24 hours. Demographic data was compared using Pearson’s χ2 test for categorical variables and students T test and Wilcoxon rank sum test for normal and non-parametric continuous variables. The association between HE and hospital mortality in LVAD patients was examined using regression modeling after adjusting for Glasgow coma scale, age, hematoma size and location and admission INR. Results: Of605 LVAD patients, we identified 40 patients with ICH. Of these, 28 patients met the inclusion criteria. Mean (SD) age of LVAD patients was 56 (10), 29% of patients were female and the majority (81%) of LVAD patients were supported by Heartmate II. The median (interquartile range [IQR]) baseline hematoma size was 20.1 ml (8.6-46.9), median (IQR) ICH score was 1 (1-2). HE occurred in 16 (57%) patients supported by LVAD, and in 50% of patients without LVAD with no difference (p=0.6).There was an association between HE and in-hospital mortality in LVAD patients after adjusting for admission ICH score and INR (OR of 20.5, 95% CI: 1.8-232.8). Conclusions: HE is a potentially modifiable risk factor for mortality. We demonstrate that LVAD patients experience HE at a similar rate to matched controls. We show that prevention of HE with anticoagulation reversal does not increase mortality.

The purpose of this study is to evaluate the relationship between hydroxychloroquine (HCQ) and diabetic retinopathy (DR) via the national health insurance research database (NHIRD) of Taiwan. All patients with newly diagnosed type 2 diabetes (n = 47,353) in the NHIRD (2000–2012) were enrolled in the study. The case group consists of participants with diabetic ophthalmic complications; 1:1 matching by age (±1 year old), sex, and diagnosis year of diabetes was used to provide an index date for the control group that corresponded to the case group (n = 5550). Chi-square test for categorical variables and Student’s t-test for continuous variables were used. Conditional logistic regression was performed to estimate the adjusted odds ratio (aOR) of DR. The total number of HCQ user was 99 patients (1.8%) in the case group and 93 patients (1.7%) in the control group. Patients with hypertension (aOR = 1.21, 95% CI = 1.11–1.31) and hyperlipidemia (aOR = 1.65, 95% CI = 1.52–1.79) significantly increased the risk of diabetic ophthalmic complications (p < 0.001). Conversely, the use of HCQ and the presence of rheumatoid diseases did not show any significance in increased risk of DR. HCQ prescription can improve systemic glycemic profile, but it does not decrease the risk of diabetic ophthalmic complications.

Abstract Background Neurocysticercosis is a Neglected Tropical Disease and an important public health issue. Our goal was to collect and analyze data regarding clinically significant gender differences among our Neurocysticercosis patients. Methods A retrospective chart search with ICD 9/ ICD 10 diagnostic code for Neurocysticercosis and neuroimaging suggestive of Neurocysticercosis was performed for clinical encounters in the hospital or affiliated clinics between years 2013–2018. After a careful chart review, patients who were clinically diagnosed with Neurocysticercosis were included in the study. T-test was used to compare means of continuous variables and chi-square test to compare proportions of categorical variables. Results Among 90 total patients included, male (49.4%) and female (50.6%) distribution were nearly identical. The mean age in females was found to be higher than males (52.5 vs 42.0, P &lt; 0.0001). Almost an equal number of males and females presented with either seizures (63.6% vs 57.8%, P= 0.85), headaches (25.0% vs 28.9%, p= 0.85), or other symptoms (11.4% vs 13.3%, p= 0.85). Males had more generalized seizures compared to females (60% vs 38%, P= 0.37), although this result was not statistically significant. Females were more likely to present with &gt; 1 lesion (82.2% vs 56.8%, P= 0.01). Males were more likely to have cystic lesions (64.7% vs 27.9%, P &lt; 0.001) compared to females who had more calcified lesions on presentation (65.1% vs 20.6%, P &lt; 0.001). Male patients were more likely to have contrast enhancement or edema surrounding the lesions (61.4% vs 33.3%, P= 0.01) and were more likely to require treatment with Albendazole/Praziquantel (75.8% vs 31.7%, P &lt; 0.001). Conclusion Although previously reported data is limited, there is a suggestion that there are gender differences in host immune response and that inflammation surrounding parenchymal lesions is more intense in females. This study suggests that men either present early in the disease phase or have different immune responses than women and require anti-parasitic therapy more frequently. More research in this aspect is needed. Disclosures All Authors: No reported disclosures

AbstractMen who have sex with men (MSM) are disproportionately affected by anal cancer, predominantly caused by high-risk (HR) human papillomavirus (HPV) infection. Currently, the nonavalent HPV vaccine provides coverage against nine HPV genotypes, including seven HR-HPV genotypes. Here, we characterize anal HR-HPV genotype distribution and associated risk factors in MSM from Toronto, Canada recruited between September 2010 and June 2012. Wilcoxon–Mann–Whitney test was used for continuous variables, Chi-square test was performed for categorical variables, and a multivariable model using logistic regression was created to assess for correlates of anal HR-HPV infection. A total of 442 MSM were recruited, with a median age of 45 (IQR 38–50) and an overall HPV prevalence of 82%. The prevalence of any HR-HPV infection was 65.3% and 50.7% in the HIV-positive and HIV-negative MSM, respectively. No participant tested positive for all genotypes covered by the nonavalent vaccine. HIV status (aOR 1.806; 95% CI 1.159–2.816), smoking (aOR 2.176; 95% CI 1.285–3.685) and the number of lifetime sexual partners (aOR 2.466; 95% CI 1.092–5.567) were independent risk factors for anal HR-HPV infection. Our findings will be useful to inform HPV vaccine rollout and HPV prevention strategies in Canadian MSM.

Abstract Background Non-prescription antibiotic use at community is a main driver of antimicrobial resistance. Cough is a common condition and prevalent in all communities, including China. This study aims to investigate the non-prescription antibiotic use for cough in China and explore to which extent antibiotic use knowledge was correctly instructed in communities.Methods A probability-proportionate-to-size (PPS) sampling method was adopted to survey from all 14 communities in Yiwu city, China. All participants were investigated by face-to-face interview on Portable Android Devices (PADs). The continuous variables were presented by mean and standard deviation (SD) or medium and inter-quartile range (IQR). The categorical variables were presented using percentage or constituent ratio. Chi-square test for univariate analysis and logistic regression for multivariate analysis were conducted to assess the odds ratios (ORs) and 95% confidence intervals (CIs), respectively.Results A total of 3034 respondents across the 14 communities and the 50 natural villages/streets completed all key items of the questionnaire. Of 2400 (79.10%) respondents stated that they experienced cough in the past 12 months with the medium age of 36.5 (IQR: 26-49) and 12.21% (293/2400) respondents had the non-prescription antibiotic use behavior. Among those 293 respondents, the proportion of non-prescription antibiotic use for cough peaked at around 16% among people aged 30-39 years old. The major sources of antibiotics were pharmacy (77.70%) and/or family storage (43.92%). As for antibiotic knowledge in 3034 participants, 61.8% participants had minimal knowledge on broad-spectrum antibiotic and 53.76% were not familiar about the effects of joint use.Conclusions Non-prescription antibiotics use for cough is prevalent in the community, especially among people in their thirties. Strengthened drug purchase regulation and well-trained professional pharmacists would be promising alternatives to ameliorate AMR. Moreover, penetrating antibiotics knowledge to common citizens and is an urgent task to alleviate antimicrobial resistance. Therefore, proactive policies and regulations should be made to improve current situations.

This study aims to assess the risk of severe forms of COVID-19, based on clinical, laboratory, and imaging markers in patients initially admitted to the ward. This is a retrospective observational study, with data from electronic medical records of inpatients, with laboratory confirmation of COVID-19, between March and September 2020, in a hospital from Juiz de Fora-MG, Brazil. Participants (n = 74) were separated into two groups by clinical evolution: those who remained in the ward and those who progressed to the ICU. Mann–Whitney U test was taken for continuous variables and the chi-square test or Fisher’s exact test for categorical variables. Comparing the proposed groups, lower values of lymphocytes ( p  = <0.001) and increases in serum creatinine ( p  = 0.009), LDH ( p  = 0.057), troponin ( p  = 0.018), IL-6 ( p  = 0.053), complement C4 ( p  = 0.040), and CRP ( p  = 0.053) showed significant differences or statistical tendency for clinical deterioration. The average age of the groups was 47.9 ± 16.5 and 66.5 ± 7.3 years ( p  = 0.001). Hypertension ( p  = 0.064), heart disease ( p  = 0.048), and COPD ( p  = 0.039) were more linked to ICU admission, as well as the presence of tachypnea on admission ( p  = 0.051). Ground-glass involvement >25% of the lung parenchyma or pleural effusion on chest CT showed association with evolution to ICU ( p  = 0.027), as well as bilateral opacifications ( p  = 0.030) when compared to unilateral ones. Laboratory, clinical, and imaging markers may have significant relation with worse outcomes and the need for intensive treatment, being helpful as predictive factors.

Background: The severe acute respiratory syndrome (SARS) causing the COVID 19 pandemic infection has affected one and all across the world and halting mosthuman activities. During the disease outbreak and country lockdown, Blood Transfusion Services faced numerous challenges to maintain the sustainability in service provision. We intend to identify the challenges faced during COVID-19 outbreak and the following imposed national lockdown. Methods: This retrospective study was done during the lockdown period from26/03/2020 to 30/05/2020 comprising 66 days to detect donor inflow declination and to compare the donor inflow with pre lockdown and post lockdown period of same duration. The periods were divided into six equal intervals to compare donor distribution patterns in lockdown, pre lockdown and post lockdown period. Mean and standard deviation was calculated for continuous variables and chi square test was done for categorical variables. Results: The donations collected during the lockdown period and post lockdown period were almost 71.37% and 62.82% less respectively when compared with the pre lockdown collection (211and 274 versus 737).While in interval periods, donor inflow was declined substantially in lockdown period and in post lockdown period, inflow was declined as of lockdown period initially but it increases as time passed. But the increment was not as such of pre lockdown period. Donor inflow in age group and time interval of donation frequency were statistically significant (p <0.00005 and p< 0.0037 respectively). Conclusion: Concerns of being infected through hospital contact, lack of public transport facilities, travel restrictions imposed by the police department, and no availability of medical student donors in the hospital setting were the main attributing factors for donor inflow.

Background: Bystander cardiopulmonary resuscitation (BCPR) improves survival after out-of-hospital cardiac arrest (OHCA). Identifying delays to starting Telecommunicator CPR (TCPR) may improve outcomes. Identifying terms callers use to describe seizure-like symptoms may improve accuracy and expedite TCPR. Methods: A total of 586 confirmed OHCA calls from 3 regional 911 centers in Arizona were reviewed between 2013 to 2016. Frequency of terms callers use to describe seizure-like symptoms were assessed. Demographics and TCPR process measures were compared between the seizure and non-seizure cohorts using Chi-square analysis for categorical variables and Kruskal-Wallis test for continuous variables. Other data points were time to start of seizure description, time to end of description, and time to start of seizure intervention. Results: There were 545 calls after exclusions. Twenty-six (.05%) had seizure-like symptoms described. Of these, “seizure” or “seizing” were used in 22 (84.6%) calls, “shaking” in 6 (23.1%), “cramping up” in 2 (7.7%) and convulsing in 2 (7.7%). Descriptions were more common in witnessed arrests [65.4% (17/26) vs. 34.6% (9/26); p=0.045] and in younger patients [median age=57 (QI=45, Q3=68) vs. 66 (Q1=51, Q3=77); p=0.036.] In calls with descriptions, telecommunicators were less likely to recognize OHCA [56.0% (14/25) vs. 74.5% (382/513), .031% (17/545) missing; (p=0.041] but bystanders were not less likely to start compressions [42.3% (11/26) vs. 57.6% (289/501), .033% (18/545) missing; p=0.122]. Median time to recognition in calls with descriptions was delayed vs. calls without descriptions [142 s (Q1=74 s, Q3=194 s), n=13, vs. 63 s (Q1=40 s, Q3=112 s), n=336; p=0.005], as was time to first chest compression [262 s (Q1=182 s, Q3=291 s), n=6 vs. 154 s (Q1=110 s, Q3=206 s), n=155; p=0.011]. Median times to start of description, end of description, and start of intervention were respectively: 33 s (Q1=20 s, Q3=40 s; 54 s (Q1=37 s, Q3=138 s; and 50 s (Q1=38 s, Q3=162 s). Conclusion: Description of seizure-like symptoms were uncommon and were associated with reduced and delayed OHCA recognition and delayed start of compressions.

e16109 Background: Total gastrectomy with lymph node dissection is curative for early gastric malignancy which accounts for 1.5% of cancer cases in the U.S. Readmissions are common postoperatively, and are associated with increased morbidity, mortality, hospital costs and decreased quality of life. We hence aim to identify incidence, impact and independent predictors for readmission in patients who underwent total gastrectomy in gastric malignancy. Methods: We conducted a retrospective cohort study of the 2017 National Readmission Database (NRD) of adult patients readmitted within 30 days after an index admission for total gastrectomy with a concomitant diagnosis of gastric malignancy. T-test was used for continuous variables and chi square test was used for categorical variables. Multivariate regression was used to identify predictors for unplanned readmissions. ICD 10 codes were used to identify diagnoses and procedures. Results: A total of 1,779 patients with gastric malignancy underwent total gastrectomy. The 30-day readmission rate was 18.5%. Main causes for readmission were sepsis, ventricular fibrillation, recurrent STEMI. Readmitted patients were more likely to be on chemotherapy. (40.1% vs 27.2%; P<0.01) and more likely to be discharged to a skilled facility (13.5% vs 17.9%; P<0.01). The total health care in-hospital economic burden of readmission was $6.5 million in total charges and $25 million in total costs. Independent predictors of readmission were major bleeding, respiratory failure requiring mechanical ventilation, peripheral parenteral nutrition, history of non-alcoholic hepato-steatosis, and prolonged length of stay. Conclusions: Readmissions after gastrectomy in patients with gastric malignancies are associated with lower in-hospital mortality yet pose a substantial economic burden on healthcare. The lower mortality might be explained by the relatively stable course and lower comorbidities of patients who become eligible for discharge after surgery. Further studies are suggested. Modifiable risk factors like malnutrition and sepsis warrant special attention to decrease readmissions and improve overall outcomes.[Table: see text]

Introduction: Some approaches to frailty screening use diagnostic or laboratory data that may be incomplete. Grip strength can identify weakness, a component of phenotype-based frailty assessment. We compared grip strength as a reductionist, phenotype-based approach to frailty screening with comorbidity and laboratory-based alternatives. Hypothesis: Grip strength and categorical weakness are correlated with the modified frailty index-5 (mFI-5) and lab values associated with frailty. Methods: Weakness based on grip, BMI, and gender was compared with mFI-5 comorbidities and lab values. Patients with at least 3/5 mFI-5 comorbidities were considered frail. Lab data collected within 6 months of grip measurement was assessed. Associations were evaluated using multivariable models and kappa. Methods: 2,597 patients had grip strength measured over 5 months. Mean age was 64.4±14.6, mean BMI was 29.5±6.9;46% were women, and 87% white. Prevalent comorbidities included hypertension (28%), CHF (22%), diabetes (29%), and COPD (26%); 9% were functionally dependent. 34% were weak, but only 13% were frail based on mFI-5. Hemoglobin, creatinine, and CRP differed significantly based on weakness ( Table ). Laboratory data were missing for 36%- 95% of patients. Multivariable models identified significant associations between weakness, hemoglobin, and all MFI-5 comorbidities. Categorical agreement between weakness and frailty was limited (kappa =0.09; 95% CL 0.0641-0.1232). Conclusion: Weakness based on grip strength provides a practical, inexpensive approach to risk assessment, especially when incomplete data excludes other approaches. Comorbidity-based assessment categorizes many weak patients as non-frail. Table. Demographic, laboratory values, and comorbidities by categorical weakness based on grip 20 th percentile. Mean values for continuous variables by weakness adjusted for gender and BMI, p-value for T-test; frequency and total percent for categorical variables, p-value represents chi-square test.
