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.

Background: Warfarin anticoagulation presents a common barrier to undergoing cardiac catheterization procedures. Using radial access and other bleeding mitigation strategies, it is not known if elevated INR truly portends an increased risk of adverse events. We sought to understand the relationship between in hospital mortality and bleeding with INR in patients undergoing coronary interventional catheterization procedures. Methods: The prospectively-collected Dartmouth Dynamic Registry was queried for all patients who underwent catheterization with coronary intervention from 2014 to 2018. Of the 5015 patients identified, 2120 patients had a recorded INR value within 24 hours of the procedure. Demographics, procedural variables, and in hospital outcomes were collected. Patients were divided into two groups: INR &lt1.8 and INR &gt1.8. Incidence of bleeding (access site hematoma &gt5cm, post procedure blood transfusion) as well as in-hospital mortality were queried for each group. Stata was used to determine statistical significance, using chi-square analysis for categorical variables and standard t-test for continuous variables. Results: Of the 2120 patients with INR values, 1968 patients were identified with INR &lt1.8 (median INR 1.1; range 0.7-1.7) and 152 patients with INR &gt1.8 (median INR 2.2; range 1.8-11.1). Patients with elevated INRs had higher acuity (urgent or emergent cases) and were older. Other baseline and procedural characteristics were similar. Outcomes between those with elevated INR and those with lower INR values were similar, including access site injury, hematoma, and need for transfusion (Table I). Overall mortality did not differ between the two groups. Conclusion: When compared to patients with INR &lt1.8, patients with INR &gt1.8 are more likely to undergo coronary intervention on an urgent or emergent basis. Despite this, there is no difference in bleeding, need for transfusion, or overall in-hospital mortality.

Ovarian Syndrome

Background: Polycystic ovarian syndrome (PCOS) is the most common endocrine disorder among women in the reproductive period. It is one of the leading causes of infertility. The manifestations of PCOS include irregular or no menstrual periods, excess body weight and facial hair, acne, heavy periods and pelvic pain. The aim of this study is to determine the efficacy of stair step protocol compared to traditional protocol in ovulation induction of polycystic ovarian syndrome (PCOS) patients in terms of increasing rate of ovulation and pregnancy. Methods: This study is non-blinded, multicenter, randomized controlled study and was carried out on infertile women attending the Fertility Clinic of Tanta University Hospital and Hurghada General Hospital. Two Hundred infertile patients with PCOS criteria and no other causes of infertility were enrolled according to inclusion and exclusion criteria. Results: Student t test was used for the continuous variables (FSH, LH, Prolactin, AMH, TSH, Free testosterone). Student t test was used for the continuous variables (Endometrial thickness, Time to ovulate (d)). Chi-square analysis was used for the categorical variables (Ovulation rate, Pregnancy rate). Chi-square analysis was used for the categorical variables (Ovulation rate per cycle). There was no significant difference between two groups as regards mild and severe side effects. Conclusions: This study concluded that stair step regimen improves the ovulation rate and pregnancy rate without any detrimental side effects compared to traditional regimen. It helps to know the sensitivity and resistance of an individual to clomiphene citrate much earlier and helps to plan ahead with alternative treatment for desired outcome. The advantage of shorter treatment period with similar side effects makes the stair step protocol suitable for use in routine clinical practice.

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.

Abstract Objective: Electronic data collection (EDC) has become a suitable alternative to paper based data collection (PBDC) in biomedical research even in resource poor settings. During a survey in Nepal, data were collected using both systems and data entry errors compared between both methods. Collected data were checked for completeness, values outside of realistic ranges, internal logic and date variables for reasonable time frames. Variables were grouped into 5 categories and the number of discordant entries were compared between both systems, overall and per variable category. Results: Data from 52 variables collected from 358 participants were available. Discrepancies between both data sets were found in 12.6% of all entries (2352/18,616). Differences between data points were identified in 18.0% (643/3,580) of continuous variables, 15.8% of time variables (113/716), 13.0% of date variables (140/1,074), 12.0% of text variables (86/716), and 10.9% of categorical variables (1,370/12,530). Overall 64% (1,499/2,352) of all discrepancies were due to data omissions, 76.6% (1,148/1,499) of missing entries were among categorical data. Omissions in PBDC (n=1002) were twice as frequent as in EDC (n=497, p<0.001). Data omissions, specifically among categorical variables were identified as the greatest source of error. If designed accordingly, EDC can address this short fall effectively.

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.

OBJECTIVE Lumbosacral fractional curves in adult spinal deformity (ASD) patients often have sharp coronal curves resulting in significant pain and imbalance. Postoperative stretch neuropraxia after fractional curve correction can lead to discomfort and unsatisfactory outcomes. The goal of this study was to use radiographic measures to increase understanding of the relationship between postoperative stretch neuropraxia and fractional curve correction. METHODS In 62 ASD patients treated from 2015 to 2018, radiographic review was performed, including measurement of the distance between the lower lumbar neural foramen (L4 and L5) in the concavity and convexity of the lumbosacral fractional curve and the ipsilateral femoral heads (FHs; L4–FH and L5–FH) in pre- and postoperative anteroposterior spine radiographs. The largest absolute preoperative to postoperative change in distance between the lower lumbar neural foramen and the ipsilateral FH (ΔL4/L5–FH) was used for analysis. Chi-square analyses, independent and paired t-tests, and logistic regression were performed to study the relationship between L4/L5–FH and stretch neuropraxia for categorical and continuous variables, respectively. RESULTS Of the 62 patients, 13 (21.0%) had postoperative stretch neuropraxia. Patients without postoperative stretch neuropraxia had an average ΔL4–FH distance of 16.2 mm compared to patients with stretch neuropraxia, who had an average ΔL4–FH distance of 31.5 mm (p < 0.01). Patients without postoperative neuropraxia had an average ΔL5–FH distance of 11.1 mm compared to those with stretch neuropraxia, who had an average ΔL5–FH distance of 23.0 mm (p < 0.01). Chi-square analysis showed that patients had a 4.78-fold risk of developing stretch neuropraxia with ΔL4–FH > 20 mm (95% CI 1.3–17.3) and a 5.17-fold risk of developing stretch neuropraxia with ΔL5–FH > 15 mm (95% CI 1.4–18.7). Logistic regression analysis indicated that the odds of developing stretch neuropraxia were 15:1 with a ΔL4–FH > 20 mm (95% CI 3–78) and 21:1 with a ΔL5–FH > 15 mm (95% CI 4–113). CONCLUSIONS The novel ΔL4/L5–FH distances are strongly associated with postoperative stretch neuropraxia in ASD patients. A ΔL4–FH > 20 mm and ΔL5–FH > 15 mm significantly increase the odds for patients to develop postoperative stretch neuropraxia.
