Abstract Liquefied petroleum gas (LPG) is a widely used environment-friendly fuel. Previous studies have shown an increasing number of LPG-related burns. Our study was designed to evaluate the epidemiologic pattern of these injuries and provide recommendations for burn prevention. This retrospective study included all patients with LPG-related burns from eight burn centers in Zhejiang Province, China between 2011 and 2015. Database variables included patient demographics, accident characteristics, and injury characteristics. The association between different categorical variables was identified using the chi-square test. And the association between two or more means of quantitative variables was analyzed by the one-way analysis of variance or t-test. A total of 1898 patients were included, 47.31% were males and 52.69% were females. The predominant age group was 31 to 70 years (74.50%), and the majority were poorly educated and the incidence peaked from June to September. The most common place of occurrence was home (74.08%) and gas leak (96.52%) was the most common cause. The four limbs (43.33%) were the most frequently affected areas; the mean burn area was 25.19 ± 20.97% of the total body surface area and most patients (46.89%) suffered from moderate burns. The mean length of hospital stay was 17.66 ± 16.55 days and the majority of patients (89.36%) recovered with a 0.84% mortality rate. Our findings reflected that the increase in incidence rate was alarming, and the causes resulting in LPG-related burns have not gained much attention yet. Therefore, this calls for simple but strict measures aiming at each hazardous step during the use of LPG to prevent these burn injuries.

IntroductionBipolar disorder is a leading cause of hospitalization in psychiatric hospitals. It is known that early detection of bipolar disorder is associated with a better prognosis.ObjectivesThe aim of this study is to conduct a demographic analysis of patients hospitalized for bipolar disorder in a single center between 2003 to 2014.MethodsRetrospective cohort study of 1230 patients admitted with bipolar disorder diagnosis from 2003 to 2014 at Centre Assistencial Emili Mira i López of Parc Salut Mar of Barcelona. We divided the study in two periods: 2003–2008 and 2009–2014. We analyzed the following variables: frequency of admissions, age, sex and days of hospital stay, comparing both periods. Chi-square test for categorical variables and Student t test for quantitative variables were applied.ResultsThe mean ages at the first and second period are 52 and 47, respectively (P < 0.001). There are no significant differences in sex and days of hospitalization. The frequency of admissions on the first and third trimesters is higher than in the second and fourth, although the differences are not statistically significant.ConclusionsDespite the large number of patients in the study, there are limitations, such as being a retrospective study and not being adjusted for confounding factors. The average age of patients in the second period is lower than in the first. This could suggest an improvement in early detection of bipolar disorder in the last years. Further research is needed to confirm this hypothesis.Disclosure of interestLG is funded by the Instituto de Salud Carlos III(CM14/00111).

The mobile learning system is the anywhere anytime learning that can happen with the smart devices with network connectivity. The learner is the one who learns through these portable smart devices in a personalized environment. So the M-Learning system should understand the needs of a learner, the learning styles and features of the devices; and accordingly should build the context of the learner. The system should adapt itself to the context of the learner, to deliver the content in the video or audio or text formats. The learning styles are identified as V for Visual, A for auditory, R for read and K for kinesthetic. In this paper two contexts – college and house has been considered for the study of Chi Square Test. The Chi Square test has been conducted to find the association and dependencies between the various categorical variables of college and house against the VARK learning styles.

AbstractObjectives: To compare growth patterns of nonfunctioning and prolactin-producing pituitary macroadenomas, and to find whether their specific growth patterns are associated with clinically significant effects on vision. Materials and Methods: From our comprehensive provincial neuropituitary registry, we retrospectively identified 35 randomly selected patients each with nonfunctioning adenomas and prolactinomas >10 mm in any dimension. MRI scans were analyzed to determine the superior and inferior growth, volume, and maximum craniocaudal height of the adenomas. Patients underwent visual field testing at diagnosis. Continuous variables were compared using Student’s t test, the Mann–Whitney U test, and ANOVA. Categorical variables were compared using the chi-square test. Results: The mean height of prolactinomas (23.2±11.3 mm) was similar to nonfunctioning adenomas (22.3±9.3 mm, p=0.8), and so were mean tumor volumes (prolactinoma=5.9±8 ml vs. nonfunctioning adenoma=4.8±5 ml, p=0.47). However, the mean suprasellar growth for prolactinomas was 2.9±5.3 mm and 7.3±4.7 mm for nonfunctioning adenomas (p<0.001), and the mean infrasellar growth was 10.2±8.0 and 5.0±6.6 mm, respectively (p=0.04). The inferior growth pattern of prolactinomas was associated with a significantly lower likelihood of having visual field abnormalities (11.4 vs. 57.1%, p<0.001). Conclusions: Prolactinomas have predominantly inferior growth compared to nonfunctioning adenomas and are less likely to cause vision changes.

Objective To estimate the time to delivery after elective cerclage removal and evaluate whether there is a difference based on the indication for cerclage placement. Study Design This was a retrospective cohort of singleton pregnancies that underwent Shirodkar cerclage placement at a single maternal–fetal medicine practice between June 2005 and June 2017. We included all scheduled elective cerclage removals >36 weeks. The primary outcome was latency to delivery. We further compared time to delivery based on the original indication for cerclage. Data were analyzed using the one-way analysis of variance and chi-square test. Results A total of 143 patients met the inclusion criteria. Of these, 40.6% were history indicated, 51.0% ultrasound indicated, and 8.4% exam indicated. The mean time from removal to delivery was 13.3 ± 8.4 days; 12.6% (18/136) of patients delivered within 24 hours of removal. When stratified by indication for cerclage, there were no significant differences for all delivery outcomes. Delaying cerclage removal to >37 weeks resulted in a statistically significantly later gestational age at delivery compared with removal between 36 and 366/7 weeks (39.0 vs. 38.3 weeks, p = 0.001). Conclusion The mean time from elective Shirodkar cerclage removal to delivery is 13 days with only 12.6% of patients delivering within 24 hours of removal.

This study evaluated the accuracy of three electronic apex locators (Root ZX, Novapex, and Justy II) in root canal length determinations using different apical file sizes, considering the apical constriction (AC) and the major foramen (MF) as anatomic references. The diameter of the apical foramina of 40 single-rooted teeth was determined by direct visual measurement and the master apical file was established. Electronic measurements were then performed using 3 instruments: the selected master apical file (adjusted file), one size smaller (intermediate file), and two sizes smaller (misfit file). The distances from the tip of files fixed in the canals to the MF and to the AC were measured digitally. Precision at AC and at MF for the misfit, intermediate and adjusted apical files was as follows: 80%/88%/83% and 78%/83%/95% (Root ZX); 80%/85%/80% and 68%/73%/73% (Novapex); and 78%/80%/78% and 65%/78%/70% (Justy II). Considering the mean discrepancies, statistically significant differences were found only for the adjusted file at MF, with Root ZX presenting the best results at MF. The chi-square test showed significant differences between the acceptable measurements at AC and at MF for the Justy II and Novapex (± 0.5 mm) regardless of file adjustment. Under the conditions of the present study, all devices provided acceptable electronic measurements regardless of file adjustment, except for Root ZX which had its performance improved significantly when the precisely fit apical file was used. Justy II and Novapex provided electronic measurements nearest to the AC.

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

Abstract Objective: To test the null hypothesis that there is no difference in facial profile shape, malocclusion class, or palatal morphology in Malay adults with and without obstructive sleep apnea (OSA). Materials and Methods: Subjects were 120 adult Malays aged 18 to 65 years (mean ± standard deviation [SD], 33.2 ± 13.31) divided into two groups of 60. Both groups underwent clinical examination and limited channel polysomnography (PSG). The mean OSA and control values were subjected to t-test and the chi square test. Results: Physical examination showed that 61.7% of the OSA patients were obese, and 41.7% of those obese patients had severe OSA. The mean body mass index (BMI) was significantly greater for the OSA group (33.2 kg/m2 ± 6.5) than for the control group (22.7 kg/m2 ± 3.5; P &lt; .001). The mean neck size and systolic blood pressure were greater for the OSA group (43.6 cm ± 6.02; 129.1 mm Hg ± 17.55) than for the control group (35.6 cm ± 3.52; 114.1 mm Hg ± 13.67; P &lt; .001). Clinical examination showed that the most frequent findings among OSA groups when compared with the control group were convex profiles (71.7%), Class II malocclusion (51.7%), and V palatal shape (53.3%), respectively; the chi square test revealed a significant difference in terms of facial profile and malocclusion class (P &lt; .05), but no significant difference in palatal shape was found. Conclusion: The null hypothesis is rejected. A convex facial profile and Class II malocclusion were significantly more common in the OSA group. The V palatal shape was a frequent finding in the OSA group.

Background: In 2013, the NIH Stroke Trials Network (StrokeNET) was established to maximize efficiencies in stroke clinical trials. Successful recruitment in future trials was required for participating sites. A high volume of cases treated is a surrogate for the potential to recruit. Among Medicare-eligible acute ischemic stroke (AIS) cases, we estimated the IV rt-PA and endovascular embolectomy treatment rates at StrokeNET Regional Coordinating Centers and their partner hospitals compared with non-StrokeNET hospitals in the United States (US). Methods: We used demographics and IV rt-PA and embolectomy rates in the 2013 Medicare Provider and Analysis Review (MEDPAR) dataset. ICD-9 codes 433.xx, 434.xx and 436 identified AIS cases. ICD-9 code 99.10 defined rt-PA treatment and ICD-9 code 39.74 defined embolectomy. Demographics and treatment rates at StrokeNET and non-StrokeNET sites were compared using t-test for proportions and Chi-square test for categorical variables as appropriate. Results: Of 386,157 AIS primary diagnosis discharges, 5.1% received IV rt-PA and 0.8% had embolectomy (Table). By June 6, 2014, StrokeNET comprised 247 acute care hospitals that discharged 48,946 (13%) out of 386,157 AIS cases. rt-PA (7.4% vs 4.8%) and embolectomy (1.9% vs 0.6%) treatment rates were higher at StrokeNET hospitals. In 2013, 36% of StrokeNET hospitals treated more than 20 AIS cases with rt-PA or embolectomy compared with 6% of non-StrokeNET hospitals (P<0.0001).Conclusions StrokeNET hospitals treat more AIS cases with acute reperfusion therapies. Thus, StrokeNET could successfully recruit in acute reperfusion clinical trials depending on study size, capture of eligible patients and the number of competing trials. We likely underestimated treatment rates due to not accounting for drip-and-ship and non-Medicare cases. To further enhance enrollments in large acute reperfusion phase 3 trials, partnership with high volume non-StrokeNET hospitals may be warranted.

Introduction: The COVID-19 pandemic has challenged the healthcare system’s capacities around the world. Due to the alarming situation, medical activities have been restricted to allocate resources to treat COVID-19-infected patients. However, medical emergencies still need urgent medical intervention. Considering the lack of reliable data regarding spinal surgeries during the COVID-19 pandemic, the present study sought to analyze the pattern of spinal surgeries in KSA. Methodology: A case series of patients who had urgent spine surgeries during COVID-19 pandemic was conducted in a tertiary care hospital. Data on patients’ demographics, COVID-19 test result, American Society of Anesthesia Score, SSS grade, diagnosis, and data related to surgery and postoperative findings were collected. All collected data were then processed and analyzed. Surgical outcomes based on source of admission were compared using Chi-square test. Result: A total of 63 patients who underwent spine surgery during the COVID-19 pandemic were included. The mean age of the patients was 53 ± 18 years and males were predominant (59%). The positive COVID-19 patients were 3%. Almost half of the patients were classified into ASA II. The majority were categorized into grade B (65%) according to SSS. The frequently diagnosed condition was fracture (33%), followed by spinal stenosis (18%) and metastatic (10%), while the most mentioned location was lumbar (61%). Postoperative complications were found in 11% of the patients. The readmission rate within 30 days, unplanned return to OR and ICU admission were 19%, 13%, and 11%, respectively. While the mean duration between admission and surgery was 8 ± 20 days, the mean duration of length of stay was 20 ± 29 days. Further, a significant association was seen between the admission source and the surgical procedure performed and surgical indication. Conclusion: It has been demonstrated that the surgical intervention was only provided to patients requiring immediate or urgent spinal management. However, the length of hospitalization and duration between hospital admission and surgery was substantially prolonged. Further studies are warranted to determine the factors leading to prolonged hospitalization and time between hospital admission and surgery.

SummaryThe aim of the study was to determine the status of SE in people with physical disabilities (PwPD) and compare SE scores between active and inactive individuals. The sample of PwPD (n = 186) was divided into two groups of those who are regularly participating in sport (active; n = 88) and those who are not participating in any sport in their leisure (inactive; n = 98). The Rosenberg Self-Esteem Scale (RSES) was used as a primary research method. 10-item scale measures global self-worth by measuring positive and negative feelings about the self. Higher scores (from 10 to 40 points) indicate higher SE. The Pearson chi-square test was used to determine the differences of 10 RSES items and total scores between active and inactive PwPD. We found that the mean score of RSES in PwPD was 28.83 points; active PwPD observed total score of RSES 30.01 points and group of inactive PwPD showed the lowest SE by achieving 27.76 points. Mean scores comparison of each RSES item between active and inactive PwPD revealed higher SE in the group of active PwPD. Significantly higher SE was presented by 4 from 10 RSES items and by total score in the group of active PwPD. The results of our study confirmed that actively living PwPD have significantly higher SE comparing those PwPD who are living sedentary life style.
