ABSTRACT

INTRODUCTION: Doximity has become integrated into the residency application process without any clear merit, comparing programs based on reputation and research. Our study aims to gather program directors’ and Chiefs/Chairs’ perspectives on the Doximity ranking system and to assess what a better system might entail.

METHODS: A 16-question survey was sent to 177 program directors and Chief/Chairs of plastic surgery residency programs. The questions covered three categories: (1) demographic information; (2) Doximity ranking perceptions; (3) input on characteristics of a better tool. The responses were statistically analyzed.

RESULTS: Ninety-three questionnaires were received (53%). Twenty-nine (31%) respondents represented programs in the Northeast, 23 (25%) South, 20 (21%) Midwest, and 21 (23%) West. Seventy-three (79%) respondents were male and 16 (17%) female. 90% of respondents (n = 84) believe Doximity rankings are not accurate, all indicating their institution should be ranked higher. No significant association between program geography and ranking satisfaction was observed (p = 0.75). Only 33% (n = 31) of respondents were aware of Doximity methodology. Most respondents (95%; n = 88) do not recommend the use of Doximity to medical students. Most participants (87%; n = 81) are willing to share resident case logs to inform a future tool. “Strength of technical training/preparedness” was ranked most highly as important training program qualities.

CONCLUSIONS: The results of this program leadership survey show dissatisfaction with and a lack of understanding of the Doximity system. When considering future steps, program leadership support a strength-based categorization system and sharing case logs to guide student decision-making.

ABSTRACT

We aimed to determine population immunity to measles in Canada, and to assess the risk of future outbreaks. We tested 11,176 sera from Cycles 2 (2009-2011) and 3 (2011-2013) cohorts from the biobank of Statistics Canada’s Canadian Health Measures Survey (CHMS) using the BioPlex 2220 MMRV IgG assay. We then tested all BioPlex negative and equivocal samples using a more sensitive Plaque Reduction Neutralization Test (PRNT). We determined the weighted proportion of positive, equivocal, and negative samples by age, sex, region and whether individuals were born in Canada. We found that 90.0% (95% confidence interval (CI): 88.2, 91.9) of samples were positive, 4.5% (95% CI: 3.4, 5.5) were equivocal and 5.5% (95% CI: 4.3, 6.7) were negative. Individuals in the 12-19 year age band had the lowest proportion positive at 78.7% (95% CI: 74.2, 83.2) and the highest proportion of positive samples was found in those 60-79 years (99.6%, 95% CI: 99.3, 99.9). Seropositivity was consistently <90% across a broad range of pediatric and adult age bands (6-39 years). We found that a slightly higher proportion of females were positive (91.9%, 95% CI: 90.1, 93.6) compared to males (88.3%, 95% CI: 85.8, 90.7). When taking into account interaction between age and born in Canada status, we found individuals born in Canada aged 19 and under were less susceptible (OR = 0.6 (95% CI: 0.4, 0.95)) compared to those born outside Canada whereas, those aged 20 and over were more susceptible (OR = 1.7 (95% CI: 1.1, 2.8)). Our findings indicate that measles immunity in Canada is below the 95% immunity threshold required to sustain measles elimination, underscoring the importance of maintaining high vaccine coverage to prevent future measles outbreaks and sustain Canada’s elimination status.

ABSTRACT

The Lapidus arthrodesis is a powerful procedure for the correction of hallux valgus with metatarsus primus varus. Yet, first ray instability may persist despite correction of the primary deformity with 2 crossed screw fixation. A third screw is often utilized as the additional point of fixation for noteworthy residual transverse plane motion, but it is not without potential complications. The suture and button fixation device may be an appropriate alternative to the third screw construct. This retrospective cohort study identified clinical / radiographic outcomes and complication rates following a third point of fixation with either a screw or suture and button fixation device in patients undergoing a modified Lapidus arthrodesis. One surgeon performed all of the Lapidus procedure with a third screw while the other surgeon performed all with a suture and button fixation device. Of 136 consecutive patients who underwent a modified Lapidus arthrodesis, 83 (61%) patients required a third point of fixation for satisfactory stabilization of the first ray. Surgical technique was similar between the 2 surgeons; however, one utilized the suture and button fixation device method (n = 36), while the other used a third screw for fixation (n = 47). Many of the clinical outcomes, radiographic results, and the union rate were similar between the 2 methods. Nineteen (40%) complications occurred in the third screw group compared to 6 (17%) in the suture and button fixation device group. However, the third screw group demonstrated 100% maintenance of deformity correction at 1 year versus 95% in the suture and button fixation device group. Although fixation with a suture and button fixation device was associated with fewer complications, a larger study is necessary to determine if these variations are statistically significant.

ABSTRACT

INTRODUCTION: The objective was to evaluate the effect of a fluoride mouth rinse and a high-fluoride toothpaste on caries incidence in patients undergoing orthodontic treatment with fixed appliances.

METHODS: In this 3-armed, parallel-group, randomized controlled trial, patients referred to the Specialist Clinic of Orthodontics, Mölndal, Sweden, were randomly allocated to 1 of the 3 groups. (1) Fluoride mouth rinse (FMR) group: 0.2 % sodium fluoride (NaF) mouth rinse plus 1450 ppm fluoride (F) toothpaste; (2) High-fluoride tootpaste (HFT) group: 5000 ppm F toothpaste; and (3) Control (CTR) group: 1450 ppm F toothpaste. The generation of a randomization sequence was performed in blocks of 30. Inclusion criteria included patients scheduled for treatment with fixed appliances in the maxillary and mandibular arch aged 12-20 years. The primary outcome variable was the change in Decayed Initial Filled Surfaces (ΔDiFS) based on radiographs taken before and after the treatment. For statistical comparisons between groups, the Kruskal-Wallis test were used for continuous variables, whereas the Mann-Whitney U-test was used for pairwise group comparisons. Furthermore, the risk ratio (RR) and 95% confidence interval (CI) based on clinically relevant cutoffs (DiFS ≥2) were calculated to compare the increase of caries during orthodontic treatment between 2 groups. The Cochran-Mantel-Haenszel method was used to adjust RR for baseline values. Blinding was employed during the caries registration and the data analysis.

RESULTS: In total, 270 participants were randomized, with 15 patients dropping out, such that 255 patients were included in the statistical analyses. Recruitment was from October 2010 to December 2012. An increase in DiFS (≥1 DiFS) during treatment was observed in 48.3% of the FMR group, 42.0% of the HFT group, and 35.6% of the CTR group. There was no significant difference between the groups regarding increased DiFS (P = 0.17). The risk of increase in DiFS ≥2 during orthodontic treatment was 31.0% in the FMR group, 25.9% in the HFT group, and 18.4% in the CTR group. The RR for an increase of ≥2 DiFS during orthodontic treatment was 1.38 (95% CI, 0.81-2.34; P = 0.23) for FMR vs CTR, 1.21 (95% CI, 0.70-2.10; P = 0.51) for HFT vs CTR, and 0.93 (95% CI, 0.57-1.49; P = 0.76) for HFT vs FMR.

CONCLUSIONS: In patients who demonstrate a low prevalence of caries and are undergoing orthodontic treatment, daily use of high-fluoride toothpaste or fluoride mouth rinse in combination with regular toothpaste does not appear to significantly alter the caries incidence compared with the use of regular toothpaste.

TRIAL REGISTRATION: The trial was registered in the FoU i Sverige research database (http://www.fou.nu/is/sverige), with registration no. 236251.

PROTOCOL: The protocol was not published before trial commencement.

ABSTRACT

The aim of this study was to investigate the effect various mediators in synovial fluid (SF) on the pathogenesis of temporomandibular disorders (TMD) and to evaluate the relationship between clinical and radiological features of temporomandibular joint (TMJ) diseases. Patients who had received SF sample during arthrocentesis because of TMD were included in this study. Clinical and radiological records were evaluated retrospectively. Enzyme-Linked ImmunoSorbent Assay (ELISA) method was used for analysis of aggrecan, adiponectin, resistin, apelin, Vascular Endothelial Growth Factor (VEGF) and Prostaglandin E2 (PGE2) in SFs. 59 joints of 41 patients were included in the study. Anterior disc displacement with reduction (ADDwR) was detected in 22 joints, anterior disc displacement without reduction (ADDwoR) was detected in 29 joints and osteoarthritis (OA) in 8. In OA group, PGE2 level was significantly higher than the other groups (p = 0.029). Aggrecan and PGE2 levels were statistically higher in joints with localized pain (p = 0.030, p = 0.029). The aggrecan level was statistically significant higher in patients who had degenerative changes in radiological examinations (p = 0.044). Resistin was correlated with PGE2 and aggrecan (p = 0.011), and apelin showed positive correlation with VEGF (p˂0.001). The detection of aggrecan and adipokines in SF may be a precursor of degenerative joint disease and it should be taken into account that the presence of localized pain in the joint area may be an early sign of degenerative changes.

ABSTRACT

BACKGROUND: Elderly patients have higher risks for complications during Ramadan fasting. Educating patients is essential for fasting safely.

AIM: To evaluate the impact of pre-Ramadan education in reducing risk of hypoglycemia and achieving glycemic control in elderly.

METHODS: A prospective study carried out in outpatients clinics of Internal Medicine department in Assiut university hospital. It included 316 type 2 diabetic patients who intended to fast. They were grouped into 2 groups; < 65 years and ≥ 65 years patients. The patients received pre-Ramadan individual education sessions. A semi-structured questionnaire was used to collect the data to stratify the risk of fasting. The study was carried out in 3 phases. Assessment of hypoglycemia and biochemical parameters after the education was the primary outcome.

RESULTS: Fasting blood glucose decreased during and after Ramadan in elderly significantly (p = 0.0001). The patients who achieved fasting blood glucose less than 8 mmol/L increased from 29.3% to 46.6% after Ramadan in elderly patients. HbA1c decreased significantly after Ramadan (p = 0.001). The main cause of breaking fast was hypoglycemia in both groups; 9% vs.7.7% in patients < 65 and ≥ 65 years respectively. The waist circumference showed significant decrease in patient with 65 years old or more (p = 0.05). Total cholesterol and LDL increased with no statistical significance in patients ≥ 65 years (p = 0.512, 0.470). Both groups showed improvement of HDL cholesterol during and after Ramadan (P = 0.0001).

CONCLUSION: Pre-fasting education had positive impact on decreasing the risk of symptomatic hypoglycemia in elderly diabetic patients.

ABSTRACT

INTRODUCTION: While avalanche fatalities have remained relatively steady per year, data suggest a possible increase in sidecountry use and snowmobile fatalities. Limited information is known regarding the accident details and preparedness among different groups of backcountry users including snowmobiles, sidecountry, and backcountry skiers, and what specific factors could contribute to their fatalities.

METHODS: Avalanche fatality reports covering all US states posted by the Colorado Avalanche Information Center available online for 10 seasons (2009-2010 through 2018-2019 seasons) were analyzed for group size, specific equipment carried, burial depth, burial time, and other details. Only reports in the 3 following categories were included in the analysis: backcountry ski/snowboard, sidecountry ski/snowboard, and snowmobile/snowbike. These aspects were compared among the 3 tourer types using statistical analyses (ANOVA).

RESULTS: Two hundred and five fatalities were analyzed (n=32 sidecountry, n=91 skier/snowboard, n=82 snowmobile/snowbike). Using 2 preparedness scores, the ski/snowboard group had the greatest distribution of high scores when evaluated by equipment carried and group size, with significant differences per group (P<0.01). Of the fatalities that were buried, burial time was related to the tourer group (P=0.04), with the ski/snowboard group having the highest proportion of burials <15 min. Burial depth was significantly different among the 3 tourer groups, with snowmobiles buried the deepest on average (P<0.01).

CONCLUSIONS: Despite limited data available on fatalities, an analysis of preparedness suggests that backcountry skiers and snowboarders are more prepared for avalanche accidents compared to snowmobiles and sidecountry users when evaluated by equipment carried and group size.

ABSTRACT

AIMS: To quantify metabolic impairment via a one-factor approach with confirmatory factor analysis (CFA) including MRI-derived visceral and subcutaneous adipose tissues and to associate it with diastolic dysfunction.

METHODS: In this cross-sectional analysis, 916 participants (53% female, mean age (SD): 56 (6)) underwent abdominal and cardiovascular MRI. With CFA a metabolic-load factor of metabolic-syndrome variables and visceral and subcutaneous adipose tissues was constructed. A piecewise structural equation model approach with adjustment for confounding factors was used to determine associations with left-ventricular diastolic function, cardiac morphology and hemodynamics.

RESULTS: Model fitting excluding blood pressure and waist circumference but including visceral and subcutaneous adipose tissues, fasting glucose, HDL-c and triglycerides was used to construct the metabolic-load factor. Evaluating measurement invariance demonstrated sex-specificity. Change in mitral early/late peak filling rate ratio was -0.12 for both males [-0.20; -0.05, p > 0.05] and females [-0.17; -0.07, p > 0.001] per SD of metabolic-load factor. Change in deceleration time of mitral early filling was -11.83 ms in females [-17.38; -6.27] per SD of metabolic-load factor.

CONCLUSION: A single latent metabolic-load factor via CFA including MRI-derived adipose tissues increased sensitivity for metabolic impairment obsoleting waist circumference and is associated with a decreased left-ventricular diastolic function, more apparent in females than in males.

ABSTRACT

INTRODUCTION: We have recently validated a meatal Stenosis (MS) severity grading system that is based on physical examination.

OBJECTIVES: The study objective was to examine the correlation between this grading system, patients’ urinary symptoms, uroflowmetry and postvoid residual parameters.

STUDY DESIGN: Patients referred for our clinic for urinary and non-urinary complaints, were prospectively enrolled. Urinary symptoms questionnaire, uroflowmetry parameters and post-voiding residuals (PVR) were assessed, and photographs of the urethral meatus were taken for each patient. The photographs were graded blindly according to the previously validated grading system and correlated with urinary symptoms, uroflowmetry parameters and PVR.

RESULTS: Overall, 75 patients were assessed (20 grade 0, 23 grade 1 and 32 grade 2). When using grade 0 as a reference, the odds ratio (OR) for reporting narrow stream was 6.4 (95%CI 1.65-24.77) and 4 (95%CI 1.18-14.16) for grade 1 and 2 respectively. OR for prolonged urination was 6 (95% CI 1.47-24.89) for Grade 1 and 2; OR for upward stream deviation was10.08 (95%CI -2.43-41.82) for grade 1 and 15.12 (95%CI – 3.74-61.17) for grade 2. Uroflowmetry results showed lower Qmax from 16.8(SD ± 8.0) ml/sec in grade 0-9.6 ml/s on grade 1 and 2 (p < 0.001) (Figure 1). PVR was not statistically different in the three groups.

DISCUSSION: Our main findings were that meatal stenosis severity grade is associated with narrow stream as reported by parent, prolonged urination, and upward deviation of urinary stream, with increasing severity with worsening stenosis. MS grade was also associated with significant worsening of uroflow measures: a lower Qmax, Qmean and a longer time-to-Qmax. Post-void residual volume was not significantly different between the different severity grades. This study showed the clinical significance of the grading system. With subjective and objective measures. The implementation of this grading system in clinics, may aid in decision making regarding surgical intervention in the appropriate patients, and avoid unnecessary procedures.

CONCLUSION: The Severity of MS seen on physical examination correlates well with obstructive symptoms and decrease of urine stream seen on uroflowmetry. These findings confirm the importance of the grading system in the evaluation of patients with MS and may be additional measure that assist in consulting parents on the indications to meatotomy.

ABSTRACT

BACKGROUND: In soft tissue sarcomas, the oncological and functional outcomes between planned excision and unplanned excision with additional wide resection remains controversial. The purpose of this study is to determine the impact of unplanned excision on oncological and functional outcomes.

METHODS: A retrospective single-center study was performed. Patients with soft tissue sarcoma surgically treated in 2005-2019 were included in this study. A total of 120 patients consisting of planned excision (PE) group (n = 88), and unplanned excision (UE) group (n = 32) were included. Overall-survival (OS), local recurrence-free survival (LRFS), metastasis-free survival (MFS), disease-free survival (DFS), incidence rate of reconstructive surgery and musculoskeletal tumor society (MSTS) score were assessed. Propensity score matching method was used in statistical analysis.

RESULTS: The 5-year survival rate of OS, LRFS, MFS, and DFS did not differ between the PE and UE groups, however, rates of reconstructive surgery were higher in the UE group (PE: 48% vs. UE: 84%, p < 0.001). These results did not differ (PE: 41% vs. UE: 82%, p = 0.012) after propensity score matching was performed to align the backgrounds with difference in tumor size and depth. For MSTS score, the total score and “pain” and “emotional acceptance” scores were higher in the PE group before propensity score matching. The “pain” and “emotional acceptance” scores were higher in the PE group after propensity score matching also.

CONCLUSIONS: Unplanned excision did not deteriorate oncological outcomes, however unplanned excision lead to unnecessary reconstructive surgery. Unplanned excision adversely affected patient-reported outcomes without worsening pure functional outcomes.
