Abstract (1) Introduction: The choices of the treatments for femoral neck fractures remain controversial. The purpose of this study is to evaluate the prognoses of the variable pitch fully threaded headless screws in the fixation of femoral neck fractures and to compare them with those of partially threaded cannulated screws. (2) Materials and Methods: Between 1st January 2012 and 31st December 2016, there were 89 patients with the main diagnose of femoral neck fracture who accepted the treatment of closed reduction cannulated screw fixation in Peking University People’s Hospital. 34 cases of partially threaded screws and 23 cases of fully threaded screws met the criterion. The characteristics, prognoses and the imaging changes of all cases were described and the differences between the two groups were compared. Statistical analyses were performed using SPSS version 23.0 (SPSS Inc., USA). Mann-Whitney U test, Analysis of Variance and Chi-square test were used. Statistical significance was defined as P value (two sided) less than 0.05. (3) Results: There was no significant difference in the general characteristics, fracture classifications and reduction quality between the two groups. The fully threaded group had a significant lower angle decrease rate (30.4% vs. 58.8%, P = 0.035), femoral neck shortening rate (26.1% vs. 52.9%, P = 0.044) and screw back-sliding rate (21.7% vs. 50.0%, P = 0.032), but a higher screw cut-out rate (21.7% vs. 0.0%, P = 0.008). No significant difference was found in the nonunion rate (8.7% vs. 0.0%, P = 0.159), avascular necrosis rate (17.4% vs. 23.5%, P = 0.744) and the good and excellent rate of Harris score (73.9% vs. 82.4%, P = 0.443). (4) Conclusion: Compared with the partially threaded screws, the variable pitch fully threaded headless screws had a lower screw back-sliding rate, femoral shortening rate, angle decrease rate and similar function score, but would result in more screw cut-outs and nonunions in Garden III-IV and Pauwels III fractures. As a conclusion, the variable pitch full threaded screws are recommended in stable undisplaced fractures rather than displaced unstable fractures. Further qualified investigations with a larger scale of patients and longer follow-up are needed in the future.

Background:YLB113 is an etanercept biosimilar approved in all indications of its etanercept Reference Product (RP). Therapeutic equivalence in terms of clinical efficacy, safety and immunogenicity was previously demonstrated in a pivotal multicenter, double-blind, randomized, parallel-group, active-control, comparative study (YLB113-002) in rheumatoid arthritis (RA) subjects.1,2 Similar incidence of treatment emergent adverse events (TEAEs) was seen in both treatment arms except for injection site reactions (ISRs) and injection site erythema (ISE), both of which were less frequent in subjects treated with YLB113.Objectives:This post-hoc analysis was performed to further evaluate the differences in the incidence of ISRs and ISE during the 24 week treatment when the subjects with RA were treated with 50 mg of YLB113 or RP given once a week as a SC injection along with methotrexate.Methods:Safety analysis set (263 in YLB113 arm and 254 in RP arm) was considered for this analysis.Local reactions at the site of injection were assessed at each of eight study visits.The number of subjects who experienced ISRs and ISE were statistically compared for YLB113 and RP. The risk difference and 95% confidence interval (CI) were computed between arms to understand the magnitude of difference in the incidence of events. The statistical significance of between group difference was tested using chi-square test.Results:The result of this analysis showed a statistically significant difference in the incidences of ISRs and ISE between subjects who received YLB113 and RP. The risk difference between YLB113 and RP arms for ISR was -9.98% (95% CI, WALD -14.81%, -5.15%) and, for ISE it was -7.94% (95% CI, WALD -11.96%, - 3.92%; Table 1). This could be possibly explained by the absence of latex in the syringe needle cap of YLB113.3Table 1.Differences in ISRs and ISEs between YLB113 and Reference Product (RP)EventYLB113N=263RPN=254YLB113 vs RPNo of subjects with events [n(%)]No of subjects with events[n(%)])Risk Diff (95%CI, WALD)P-value (Chi-Square)Injection-site reactions10 (3.8%)35 (13.8%)-9.98% (-14.81%, -5.15%)<0.0001Injection-site erythema5 (1.9%)25 (9.8%)-7.94% (-11.96%, -3.92%)0.0001Conclusion:YLB113 has shown statistically significant lower incidences of ISRs (P-value <0.0001) and ISEs (P value 0.0001) compared to RP.

Aim: This study aimed to review the clinical findings and surgical intervention of the hip fracture at the Hue University Hospital in Vietnam. Methods:The data of proximal femoral fractures was collected retrospectively. All patients, in a period of 5 years, from Jan 2008 to December 2012, suffered either from intertrochanteric or femoral neck fractures. The numbers of patients were gathered separately for each year, by age groups (under 40, 40-49, 50-59, 60-69, 70-79, older) and by sex. We analyzed what kind of treatment options were used for the hip fracture. Results:Of 224 patients (93 men and 131 women) studied, 71% patients are over 70 years old, 103 women and 56 men (p<0.05). For patients under 40 years, there were 1 woman and 11 men (p<0.05). There were 88 intertrochanteric and 136 femoral neck fractures. There was no significant difference in the two fractures between men and women. The numbers of hip fracture increased by each year, 29/224 cases in 2010, 63/224 cases in 2011, 76/224 cases in 2012. Treatment of 88 intertrochanteric fractures: 49 cases (55.7%) of dynamic hip screw (DHS), 14 cases of hemiarthroplasty (15.9%), 2 cases of total hip replacement (2.3%). Treatment of 136 femoral neck fractures: 48 cases of total replacement (35.3%), 43 cases of hemiarthroplasty (31.6%), 15 cases of screwing (11%). In cases of 40 patients (17.9%) hip fracture was managed conservatively, 23 were femoral neck fractures and 17 were intertrochanteric fractures. Conclusions: Hip fracture is growing challenge in Hue medical university hospital. The conservative approach is still high in people who could not be operable due to severe medical conditions as well as for patients with economic difficulties. Over 70% of the hip fractures in people 70+ are caused by osteoporosis. The number of hip fracture is increasing in the following years, most likely due to the increase in the prevalence of osteoporosis. Early detection and prevention of osteoporosis should be addressed, particularly in high risk population. More aggressive surgical approach should be implemented in order to improve the quality of life in patients with hip fractures. Key words:Hip fracture.

Abstract Background The coronavirus disease 2019 (COVID-19) pandemic has resulted in the rapid uptake of telemedicine (TM) for routine cardiovascular care. Objectives To examine the predictors of TM utilization among ambulatory cardiology patients during the COVID-19 pandemic. Methods In this single centre retrospective study, all ambulatory cardiovascular encounters occurring between March 16th - June 19th, 2020 were assessed. Baseline characteristics by visit type (in-person, TM-phone, TM-video) were compared using Chi-square and student t-tests, with statistical significance defined by p value &lt; 0.05. Multivariate logistic regression was used to explore the predictors of TM versus in-person care. Results 8446 patients (86% Non-Hispanic White, 42% female, median age 66.8 +/- 15.2 years) completed an ambulatory cardiovascular visit during the study period. TM-phone (n = 4,981, 61.5%) was the primary mode of ambulatory care followed by TM-video (n = 2693, 33.2%). Non-Hispanic Black race (OR 0.56; 95% CI: 0.35 - 0.94, p-value=0.02), Hispanic ethnicity (OR 0.53; 95% CI: 0.29 - 0.98, p = 0.04), public insurance (Medicaid OR 0.50; 95% CI:0.32 – 0.79, p = 0.003, Medicare OR 0.65; 95% CI: 0.47– 0.89, p = 0.009), zip-code linked median household income (MHI) of &lt;$75,000, age &gt;85 years, and patients with a diagnosis of heart failure were associated with reduced access to TM-video encounters and a higher likelihood of in-person care. Conclusions Significant disparities in TM-video access for ambulatory cardiovascular care exist among the elderly, lower income, as well as Black and Hispanic racial/ethnic groups.

Abstract Introduction Burn camps provide a unique environment and activities for children that have experienced a burn-injury. Positive outcomes from attending burn camp include increased self-esteem, decreased feelings of isolation and a greater sense of self-confidence. In a 3-year retrospective review of camper evaluations from one of the largest and longest running week-long burn camps in the nation for ages 5–17, we aimed to assess if a child’s gender, age, TBSA or ethnicity affected the impact that burn camp had on a child. Methods A 3-year retrospective review of a Burn Camp’s camper evaluation forms was conducted for campers that attended burn camp between 2017–2019. Camp rosters were reviewed to determine the camper gender, age, TBSA and ethnicity. Camper self-evaluation forms completed at the end of each camp session were reviewed to record camper responses to questions regarding their opinions on the impact camp had on them as well as how camp will impact their lives once they return home. Categorical variables were summarized as frequency and percentage, and continuous variables were described as median and range. To check the relationship between two categorical variables, Chi-square test was used. To compare the continuous variable among groups, Kruskal-Wallis ANOVA was used. Statistical significance was declared based on a p value&lt; 0.5. Results Within 2017–2019, there were 413 camper records. Participants’ demographic characteristics are summarized in Table 1. There were 208 males (50.3%) and 205 females (49.6%). The median age of campers were 11.86, 12.44 and 12.45 for 2017–2019, with the range from 5.16 years to 17.96 years. The median TBSA were 20, 20 and 18 for 2017–2019, with the range from 0.08 to 90. Collectively there were 47.7% Hispanic (n= 197); 24.2% Whites (n=100); 13.1% Black (n= 54); 4.6% Asian (n=19) and 7.7% Other (n=32). There were 395 camper self-evaluation forms submitted. Results of three questions there we were interested in are summarized collectively in Table 2. 57% of campers responded, “Yes, Definitely” to the question “After going to this event, will you feel more comfortable being around your classmates or friends?” 54% responded, “ Yes, Definitely” to the question “Do you feel more confidents in sharing your burn story with others when returning home?” and 51% responded “Yes, Definitely” to “Did you learn anything that will help you when you return home?” Conclusions In analyzing the camper responses, there was no statistically significant difference in responses comparing gender, age, TBSA or ethnicity.

Abstract Objectives The purpose of this study was to analyze and to compare retrospectively the characteristics, the treatment process, and the prognosis of cracked teeth by comparing recent data with data from 10 years ago. Materials and Methods Sixty-eight cracked teeth from March 2009 to June 2010 (2009 data) and 185 cracked teeth from March 2019 to June 2020 (2019 data) were analyzed. The characteristics of cracked teeth and the treatment method depending on probing depth, caries, and symptoms, and prognosis depending on pocket depth and apical lesions were analyzed using R version 3.3.3 (R Foundation for Statistical Computing, Vienna, Austria) and T&F version 3.0 (YooJin BioSoft, Korea). To compare proportions, the two-sample proportion test was performed. The distribution of proportions within the samples from 2009 and 2019 data was analyzed using the Chi-square test or binomial test. A p-value <0.05 was considered to indicate statistical significance. Results Significantly fewer cracked teeth received root canal treatment before crown in 2019 than in 2009 (p = 0.032). In both 2009 and 2019, symptomatic cracked teeth and those with deep periodontal pockets (>6 mm) were significantly more likely to receive root canal treatment. In both years, cracked teeth with a probing depth less than 6 mm or without an apical lesion were significantly more likely to be asymptomatic at 3-month and 6-month follow-ups (p < 0.001). Conclusion Cracked teeth with a deep periodontal pocket or symptoms had a higher likelihood of endodontic treatment, and the presence of a deep periodontal pocket or apical lesion was associated with a higher risk of persistent symptoms. Therefore, clinicians should consider these factors when planning treatment and predicting patients’ prognosis.

Introduction: Pain during the injection of anesthetic agents may be distressing and can reduce the acceptability of an otherwise useful agent such as propofol during daycare surgeries. Lidocaine and ketamine both are used as pre-treatment to decrease propofol induced pain. This study aims to compare the effectiveness of ketamine injection to decrease propofol-induced pain in comparison to lidocaine injection. Methodology: This is a prospective cross-sectional comparative study. Eighty-nine cases were divided into two groups where group K received ketamine 2 ml (0.2 mg/kg) whereas group L received lidocaine 2% 2ml (0.5 mg/kg) after venous occlusion with rubber tourniquet. One-fourth dose of propofol was injected 1 min after release of tourniquet and pain accessed at 0, 1, and 2 minutes of propofol injection with a verbal response and behavioral signs. Chi-square test and paired T-test were used and a p-value less than 0.05 was considered significant. Result: Regarding hemodynamic, oxygenation, and adverse effects there was no significant difference. Immediately after propofol injection, only 1 patient of the ketamine group had mild pain (2.22%) while 12 patients from the lignocaine group had mild pain (27.27%) with a p-value of 0.009. Also after 2 minutes of propofol injection, only 12 cases had mild pain i.e. 13.48% (1 from ketamine group i.e. 2.22% and 11 from lidocaine group i.e. 25%) with p-value of 0.002. Conclusion: Our study helps prove low-dose ketamine is more effective in reducing the incidence and severity of pain on injection of propofol in comparison to Lidocaine with better hemodynamic stability.

Surgery Rates

Background and Objective. Intracapsular fractures of the femoral neck account for a major share of fractures in the elderly. Open reduction and internal fixation has been shown to have a higher rate of revision surgery than arthroplasty. The aim of this study was to assess and compare the rates of revision surgery performed after internal fixation and primary total hip arthroplasty. Material and Methods. Between 2004 and 2006, 681 intracapsular femoral neck fractures in 679 consecutive patients were treated with internal fixation or total hip arthroplasty at our institution. Revision surgery rates were evaluated at 1-, 3-, 6-, 12-, and 24-month follow-up. Results. There was no significant difference in the ratio of internal fixation to total hip arthroplasty during 2004–2006 (P=0.31). The mean rate of total hip arthroplasty was 19.1% with a lower rate being among patients younger than 60 years. Revision surgery rates at the 2-year followup were higher in the internal fixation group compared with total hip arthroplasty group (28.9% vs. 7.0%, P<0.001). Patients who underwent internal fixation were at a 4-fold greater risk of having revision surgery at the 2-year follow-up than those who underwent total hip arthroplasty (odds ratio, 4.11; 95% CI, 1.95–8.65; P<0.001). Age was a significant risk factor for revision surgery after total hip arthroplasty (hazard ratio, 0.93; 95% CI, 0.87–0.98; P=0.02), but not significant after the internal fixation (P=0.86). Conclusions. Higher revision surgery rates after internal fixation favors arthroplasty as a primary choice of treatment for the femoral neck fractures.

Introduction: The study aimed to evaluate the knowledge and awareness of orthodontics, a specialty of dentistry,amongst Medical Students. Materials and Method: A sample of 550 students (279 female, 226 male aged between 18 and 36 years) were attented.Of the subjects, 58.6% (n = 296) were preclinical students, while 41.4% (n = 209) were clinical students. The students were informed about the questionnaire and asked to fill in the questionnaire forms. For the comparison of data between groups (gender, level of education), the chi-square test was used. A chi-square test was used for statistical evaluation and the p-value < 0.05 was considered statistically significant. Result: 385 students (76.2%) had heard the term orthodontics although 41.2% of the subjects knew that orthodonticswas concerned with malocclusions and their treatment. The question about treatment procedures was answeredas scaling by 35.8%, tooth polishing by 40%, tooth aligning by 89.9% of the students. The percentage of knowingorthodontics to be related to tooth aligning showed a significant difference between female and male (p = 0.006), andpreclinical and clinical students (p = 0.033). Of the participants, 42.8% thought that dentures, 83% brackets, 78.8% ofremovable appliances were used by orthodontists. Conclusion: Our results have shown that medical students should have more information about orthodontics, aspecialty of dentistry.
