Project description:The aim of this study was to develop a Spanish version of the Learner Satisfaction Survey (LSS-S) and to analyze its psychometric properties. The questionnaire was administered to a sample of 1,194 university students. Validity evidence based on the instrument’s internal structure and on relationships with other variables (personality and motivation) were analyzed. In addition, reliability of test scores and differences by gender and area of knowledge were examined. The results revealed a factor structure with adequate fit indices based on five first-order factors (learner–content, learner–instructor, learner–learner, and learner–technology interactions, and general satisfaction) and one second-order factor (total score for academic satisfaction). Scores on the LSS-S were positively correlated with scores on conscientiousness, intrinsic motivation, and identified regulation, and negatively correlated with scores on neuroticism and amotivation. Although the magnitude of correlations with personality traits was small, those with motivational factors were moderate or strong. Reliability of LSS-S factor scores may be considered satisfactory, with McDonald’s omega ranging from 0.80 to 0.86. These results indicate that the LSS-S has satisfactory psychometric properties and that it is an adequate tool for measuring satisfaction with online courses among Spanish learners in higher education.

Project description:ObjectiveTo evaluate the satisfaction of asymptomatic subjects who self-referring Whole-Body Magnetic Resonance Imaging (WB-MRI) for early cancer diagnosis.MethodsSubjects completed a pre-examination questionnaire, while waiting for their WB-MRI examination, recording demographics, expected discomfort, perceived knowledge and usefulness of the procedure and health risk perceptions, as well as a post-examination questionnaire, measuring discomfort experienced, acceptability and satisfaction with WB-MRI. We examined which factors influenced discomfort and satisfaction associated with WB-MRI.Results65 asymptomatic subjects (median age 51; 29 females) completed the questionnaire. Before WB-MRI, 29% of subjects expected discomfort of some form with claustrophobia (27.7%) and exam duration (24.6%) being the most common concerns. Experienced discomfort due to shortness of breath was significantly lower than expected. This difference was significantly associated with the personal risk perception to get a disease (p = 0.01) and educational level (p = 0.002). More specifically, higher level of perceived personal risk of getting a disease and lower level of education were associated with higher expected than experienced discomfort. Similarly, experiencing less claustrophobia than expected was significantly associated with gender (p = 0.005) and more pronounced among females. A majority (83%) of subjects expressed high levels of satisfaction with WB-MRI for early cancer diagnosis and judged it more acceptable than other diagnostic exams.ConclusionsAsymptomatic subjects self-referring to WB-MRI for early cancer diagnosis showed high levels of satisfaction and acceptability with the examination. Nevertheless, a relevant proportion of participants reported some form of discomfort. Interestingly, participants with higher perceived personal risk to get a disease, lower education and females showed to expect higher discomfort than experienced.Advances in knowledgeScope exists for measures to assess expected feelings and develop personalized interventions to reduce the stress anticipated by individuals deciding to undergo WB-MRI for early cancer diagnosis.

Project description:ProblemWritten feedback is often overly positive, nonspecific, and difficult to interpret. Learner satisfaction with written feedback is low and obtaining written feedback that encourages self-reflection is challenging. Improving feedback quality is laborious and only modestly effective.ApproachThe authors developed the LEAF (Learner-Engaged Analysis of Feedback) method to improve learner satisfaction with, and reflection on, existing written feedback. The method pairs a learner and coach to methodically identify themes in the learner's written feedback. Themes occurring more frequently or less frequently than typical offer areas for reflection, as they may identify learners' relative strengths or weaknesses. The method was introduced at the Massachusetts General Hospital in 2017 during program director (PD) meetings with anesthesiology residents. In 2018, resident satisfaction was measured (1 to 5 Likert-type questions, 1 = "not at all satisfied," 5 = "extremely satisfied") for 4 feedback sources, 2 related to the LEAF method (PD meetings, written feedback) and 2 unrelated (verbal feedback, mentor feedback). Residents' comments were qualitatively assessed to explore the impact on self-reflection.OutcomesResidents who had participated in a LEAF session (n = 54), compared with those who had not (n = 11), reported higher satisfaction with written feedback (mean 3.1 versus 2.5, d = 0.53, P = .03) and PD meeting feedback (mean 3.8 versus 2.8, d = 0.80, P = .03). There were no significant differences between groups for satisfaction with feedback unrelated to the LEAF method. Qualitative analysis of comments suggested that residents found the method useful for providing holistic self-assessment, facilitating goal setting, uncovering blind spots, and improving feedback interpretation.Next stepsNext steps should include studies determining if the association between increased learner satisfaction with written feedback and the LEAF method is causal, and whether this feedback process changes learners' subsequent behaviors.

Project description:Cataract is the leading cause of non-refractive preventable blindness, and comprehensive strategies to increase cataract surgery rates are imperative, including high-quality supportive patient education. We evaluated the effectiveness of non-physician pre-surgical counselors teaching patients about cataract and cataract surgery in improving patient knowledge, decisional conflict, and satisfaction.A survey was given before and after 61 newly-diagnosed cataract patients underwent pre-surgical counseling at the Aravind Eye Hospital, Madurai, India. The survey measured change in cataract knowledge and decisional conflict, a measure of anxiety surrounding the decision to undergo surgery, along with patient satisfaction. Multiple regression was used to identify factors that influenced change in knowledge.Both patient knowledge scores and decisional conflict scores improved following counseling (mean difference +2.0, p?=?0.004 and +8.4, p?<?0.0001, respectively). Multiple regression analysis identified female sex (??=?2.5, p?<?0.001) and being illiterate (??=?1.7, p?=?0.04) as important predictors of increased knowledge post-counseling.Counseling both improved knowledge and reduced decisional conflict about cataract surgery, particularly among patients who had traditionally had more limited access to healthcare such as women and illiterate patients. Increased use of high quality counseling might help to further reduce the global burden of cataract and other forms of blindness.

Project description:Postthrombotic syndrome is characterized by a fibrotic vein injury following deep vein thrombosis (DVT). We sought to quantify the change in vein wall thickness in patients who fail to resolve DVT by 6 months and whether there were differences in blood or plasma levels of inflammatory proteins associated with venous remodeling.Patients presenting with confirmed lower extremity DVT were prospectively recruited for this study. Duplex imaging of the lower extremity venous system was performed, and blood was collected at entrance and repeat evaluation with blood draw and ultrasound imaging at 1 and 6 months. DVT resolution and thickness of the vein wall was quantified by ultrasound imaging in each segment affected by thrombus, and a contralateral, unaffected vein wall served as a control. Gene and protein expression of inflammatory markers were examined from leukocytes and serum, respectively. Analysis of variance or Student t-tests were used, and a P < .05 was significant. N = 10 to 12 for all analyses.Thirty-two patients (12 patients with DVT resolution at 6 months, 10 patients with persistent thrombus at 6 months, and 10 healthy controls) were compared. Both resolving and nonresolving DVT were associated with a 1.5- to 1.8-fold increased vein wall thickness at 6 months (P = .008) as compared with nonaffected vein wall segments. However, the thickness of the affected segments was 1.4-fold greater in patients who had total resolution of the DVT by 6 months than in patients who had persistent chronic thrombus 6 months after presentation (P = .01). There was a four- to five-fold increased level of matrix metalloproteinase-9 (MMP-9) antigen in thrombosed patients compared with nonthrombosed patient controls (P < .05), while Toll-like receptor-9 (TLR-9) gene expression was three-fold less than controls (P < .05) at enrollment. D-dimer and P-selectin were higher in thrombosed as compared to controls at diagnosis but not at 6 months. Both TLR-4 (marker of inflammation) and P-selectin gene expression were higher in leukocytes from patients with chronic DVT compared with those who resolved at 1 month after diagnosis (P < .05).This preliminary study suggests ongoing vein wall remodeling after DVT, measurable by ultrasound and associated with certain biomarkers. At 6 months, the vein wall is markedly thickened and directly correlates with resolution. This suggests that the vein wall response is initiated early following thrombus formation and persists even in the presence of total resolution.

Project description:Massive Open Online Courses have become a frequent platform for learners to acquire knowledge. This study aims to explore multiple factors influencing learner retention in MOOCs during the COVID-19 pandemic. To address this, we collected quantitative and qualitative data from questionnaires and qualitative data from interviews and then analyzed them through the Partial Least Square-Structural Equation Modeling to test 14 research hypotheses. The proposed research model and research hypotheses are empirically tested with 243 participants across the world. According to the results, support is found for all of the 14 research hypotheses. We confirmed 14 factors influencing learner retention in MOOCs. The result is beneficial for designers and manufacturers of MOOCs to improve the quality of the products and facilitate online or blended learning during this special time. It could also help students improve their learning experiences. Future research could examine influencing factors of learner retention in MOOCs with interdisciplinary cooperation.

Project description:We describe the case of a baby-girl affected by the Koolen-de Vries syndrome (KdVS), with epilepsy. Our patient has microdeletions in the 17q21.31 region (array CGH). Therapy with Levetiracetam showed a relatively lack of efficacy, while adding a low dose of Topiramate in the therapy allowed the complete seizures control. KdVS is a rare syndrome and its epilepsy features and seizures treatment are not well known by pediatric neurologists. However, with broader use of array CGH, an increasing number of cases are likely to be identified and their description, including response to specific medications, can facilitate recognition and treatment. The complex treatment of epilepsy should be part of the global management and counseling in these composite patients.

Project description:Background:The flipped classroom is a teaching approach with strong evidence for effectiveness in undergraduate medical education. Objective data for its implementation in graduate medical education are limited. Objective:We assessed the efficacy of the flipped classroom compared with standard approaches on knowledge acquisition and retention in residency education. Methods:During academic year 2016-2017, 63 medical interns in a large academic internal medical residency program on their ambulatory block were randomized to a flipped classroom or standard classroom during a 6-hour cardiovascular prevention curriculum. The primary outcome was performance on a 51-question knowledge test at preintervention, immediate postintervention, and 3- to 6-month postintervention (delayed postintervention). Secondary outcomes included satisfaction with the instructional method and preparation time for the flipped classroom versus standard approach. We also examined feasibility and barriers to the flipped classroom experience. Results:All 63 interns (100%) responded during the preintervention period, 59 of 63 (94%) responded during the postintervention period, and 36 of 63 (57%) responded during the delayed postintervention. The flipped classroom approach significantly improved knowledge acquisition immediately after the curriculum compared with the standard approach (knowledge test scores 77% versus 65%, P?<?.0001). This effect was sustained several months later (70% versus 62%, P?=?.0007). Participants were equally satisfied with the flipped classroom and standard classroom. Conclusions:A flipped classroom showed greater effectiveness in knowledge gain compared with a standard approach in an ambulatory residency environment.

Project description:BACKGROUND:Blindness or visual loss is the most serious complication resulting from facial hyaluronic acid (HA) injection. In this study, three recent clinical cases were analyzed, and the relevant anatomy of cadavers was evaluated to investigate the mechanism behind visual impairment due to HA injection. METHODS:Three patients with different extents of visual loss after HA injection were studied. Ophthalmic testing and corresponding treatments were performed, and the clinical progress was observed. In addition, thirty-six fresh Asian cadaver hemifaces were anatomized to investigate the morphology of the ophthalmic artery and its branches. The minimum dose of HA for central retinal artery embolism was calculated based on the ophthalmic arterial volumes of cadavers. RESULTS:Visual impairment was more severe in central retinal artery occlusion and combined intraocular branch occlusion than in posterior ciliary artery occlusion. During follow-up, no improvement was observed in terms of visual impairment. Cadaver study reconfirmed that the ophthalmic artery included facial and intraocular branches. The ophthalmic arterial volumes running from the supraorbital artery and supratrochlear artery to the central retinal artery were 0.083 cm3 and 0.089 cm3, respectively. CONCLUSIONS:The severity of blindness caused by HA injection may be associated with the occlusion site. Our clinical observations indicate that conventional treatments, such as retrobulbar hyaluronidase injection, are insufficient to relieve visual impairment. Injecting as little as 0.08 ml of HA into the facial branch is enough to cause central retinal artery embolism. Limiting the volume per injection could represent a simple prophylactic strategy.

Project description:To assess the clinical and anatomical causes of cutaneous paresthesia after internal fixation of clavicle fractures.This study included 135 patients who underwent internal fixation of clavicle fractures from May 2013 to June 2016 at the First and Second Affiliated Hospital of Guangxi Medical University. The incidence of postoperative supraclavicular nerve injury, the duration of numbness, and improvements after plate removal were retrospectively analyzed. Seven human cadaver specimens were subsequently dissected to analyze the supraclavicular nerve and its relationship to numbness.Of the 135 patients who underwent internal fixation of clavicle fractures, 26 (19.3%) experienced postoperative cutaneous paresthesia, with 22 (16.3%) and 4 (2.8%) experiencing numbness and pain, respectively. The most intense numbness occurred during the first operative month. Of the 22 patients with numbness, 1 (4.5%), 1 (4.5%), and 20 (90.1%) patients reported mild, moderate, and severe numbness, respectively. Two patients described increased awareness of numbness when in contact with clothes, 2 were psychologically affected by numbness, and 20 (90.1%) reported reduced severity of numbness over time. At the last follow-up, numbness was found to persist in 2 (1.5%) patients. None of the patients was bothered by numbness. Cadaver dissection showed that the supraclavicular nerve emerged from the 1/2 posterior edge of the cervical sternocleidomastoid muscle and subsequently divided into 3 branches, with the lateral branch 2.26 ± 1.17 cm from the lateral margin of the acromion, the middle branch near the mid-clavicle, and the medial branch 2.03 ± 0.85 cm from the sternal lateral margin.Cutaneous paresthesia is common following internal fixation of the clavicle. Anatomic analysis showed that the nerve could be easily injured during clavicle operation. Numbness improved in most patients, but persisted for up to 2 years and was even permanent in a few. Most patients considered numbness as an insignificant factor in their daily lives.
