Self-Efficacy of Providers of Early Intervention Services to Young Children with Visual Impairments and Their Families
Authors: Ely Mindy S. , Ostrosky Michaelene M. , Burke Meghan M. 
Published: March 2020

Introduction: Anthony cautions that the training of teachers of students with visual impairments (i.e., blindness and low vision) and orientation and mobility (O&M) specialists covers a broad age range, which may result in limited curricular content essential for those who will work with very young children with visual impairments. The current study focuses on the self-efficacy of vision professionals regarding their work with infants and toddlers in using evidence-based approaches found in the early childhood literature. Methods: Teachers and O&M specialists ( n = 109) from 11 states participated in a survey of perceptions of self-efficacy and working with infants and toddlers with visual impairments. Correlates of preparedness, experience, vision-specific self-efficacy, and early intervention self-efficacy were investigated. Results: Participants indicated that they felt inadequately trained to work with infants and toddlers. Self-efficacy measures regarding motivation to implement vision-specific recommended practices were higher than motivation to implement early intervention practices; however, self-efficacy measures for early intervention confidence and practice were higher than vision-specific confidence and practice. Although participants’ ratings of the vision training program they attended were not correlated with their own self-efficacy measures, the amount of early childhood education content reported by participants was significantly correlated with all self-efficacy measures. Further, experience was correlated with self-efficacy. Discussion: Results support the need for a greater emphasis on early intervention content in visual impairment training programs. Additionally, the fact that half of the respondents in this study were over 50 years of age suggests that a turnover in personnel is imminent. Inevitably, this new workforce will lack experience. Information for practitioners: Professional preparedness that includes a strong foundation in recommended practices in early childhood will strengthen the workforce and should ultimately improve services to infants and toddlers with sensory disabilities and their families. Practitioners may need to seek out this specialized training.

Background Pseudomingocele is a postoperative fluid collection adjacent to the dural membrane. The distinction of pseudomeningocele from other postoperative collections is very important. Purpose To show the efficacy of three-dimensional (3D) T2-weighted sampling perfection with application-optimized contrasts using a different flip-angle evolution (SPACE) magnetic resonance imaging (MRI) sequence in the diagnosis of pseudomeningocele in which conventional MRI sequences may be insufficient. Material and Methods A total of 10 patients were included in the study. All of these patients also had 3D T2-SPACE high-resolution volumetric MR image in addition to conventional cervical and cerebral MR sequences. All MR examinations were reviewed by two neuroradiologists. Results Pseudomeningocele neck was shown in six patients by both conventional sequences and SPACE sequence. In two patients, the neck was only shown in the SPACE sequence. Four pseudomeningocele necks were shown to have flow void with both conventional sequences and SPACE sequence. Flow void could only be demonstrated by SPACE sequence in two patients. Conclusion A T2-SPACE sequence can show the presence of pseudomeningocele neck and flow void even in cases where conventional MRI cannot show, thus contributing to the diagnosis of pseudomeningocele. Therefore, especially in postoperative imaging, the T2-SPACE sequence may be included in routine sequences to make the differential diagnosis correctly.

Objective There is a close association between erectile dysfunction (ED) and cardiovascular disease (CVD). This study aimed to investigate Chinese physicians’ understanding of this association. Methods A total of 651 physicians, including 245 cardiologists and 406 urologists, participated in our investigation through WeChat. Results Participants with more professional experience, a doctoral/postdoctoral degree, and an intermediate/senior title were significantly more likely to be aware of a close association between ED and CVD. Urologists had a significantly better understanding of the association of severity between both diseases, showed more positive attitudes towards phosphodiesterase type 5 inhibitor application in patients with CVD and systematic treatment, and gave greater consideration to both diseases during follow-up visits than did cardiologists. Men had a significantly better understanding of the associated severity of the two disorders and managed the two diseases together more actively than did women. Department, sex, professional experience, education, and affiliated hospital level significantly affected systematic management of ED and CVD. Conclusion Most physicians from cardiology and urology are aware of the association between ED and CVD, but this awareness may be insufficient. Department, sex, professional experience, education background, and professional title are significant factors associated with perception of this association.

Objective Using the Twente Medical Systems international B.V. (TMSi) electromyography (EMG) system, active signal shielding was applied to clean signals and create data without interference and cable movement artifacts. TMSi, used in high-density surface EMG pattern recognition, controls myoelectric rehabilitation robots, yet few have studied how active signal shielding influences pattern recognition. This study aimed to investigate how active signal shielding used within the TMSi influenced motion pattern recognition. Methods Surface EMG of dominant side forearm and hand muscles was studied in eight healthy participants. The common component’s influence was accessed by the classification performance of wrist and hand functional movements. Results The classification performance of EMG signals with the common component was obviously lower than signals without the common component using one to five electrodes. Conversely, a higher motion classification performance was achieved using signals with the common component using over 12 electrodes. Optimal channel distribution was examined based on the sequential feed-forward selection method, showing that the common component affected the optimal channel location. Conclusions Active signal shielding in the TMSi improved classification accuracy in motion pattern recognition when over 12 electrodes were used. The optimal channel distribution was related to the common component when using the TMSi.

Objective This study explored the effects of obesity on clinical manifestations, disease activity and organ damage in Korean patients with systemic lupus erythematosus (SLE). Methods We assessed 393 SLE patients annually for three consecutive years based on demographic information, clinical manifestations, laboratory findings and Physician Global Assessment, Systemic Lupus Erythematosus Disease Activity Index (SLEDAI)-2000 and Systemic Lupus International Collaborating Clinics (SLICC) damage index (SDI) scores. Patients were grouped by body mass index (BMI): normal weight, BMI <23 kg/m2; overweight, 23 kg/m2 ≤BMI <25 kg/m2; obese, BMI ≥25 kg/m2. The impact of obesity on clinical outcomes was assessed using univariate and multivariate analyses. Results Of the 393 patients, 59 (15.0%) were obese at enrollment. They had more comorbidities compared with non-obese patients, including diabetes, hypertension, hyperlipidemia and pulmonary hypertension. Nephritis at enrollment and newly developed nephritis during follow-up were more common ( p = 0.002 and p = 0.002, respectively) and Physician Global Assessment and SDI scores were higher in these patients for three consecutive years ( p = 0.017 and p = 0.039, respectively). Multivariate analysis revealed that obesity was significantly associated with development of nephritis during follow-up (odds ratio = 26.636; 95% confidence interval, 11.370–62.399; p < 0.001) and cumulative organ damage (odds ratio = 4.096; 95% confidence interval, 2.125–7.894, p < 0.001). Conclusions The incidences of newly developed nephritis and cumulative organ damage were higher in obese SLE patients than in non-obese SLE patients.

Published: March 2020

Background: Chronic pain after moderate-to-severe traumatic brain injury (TBI) is associated with notable sensory alterations. Although the incidence of TBI is rapidly growing in older populations, elderly individuals have been largely excluded from sensory testing studies, thus limiting evidence regarding the influence of age on pain-related sensory alterations after TBI. This study aimed to investigate the effect of age on the sensory profiles of patients with and without chronic pain after moderate-to-severe TBI. Methods: Thermal and mechanical quantitative sensory testing were performed on the painful and contralateral body regions in TBI participants with pain (TBI-P) and on both forearms in TBI participants without pain (TBI-NP). Descriptive information about chronic pain and psychological comorbidities was assessed using validated questionnaires. Results: Participants included 37 young (18–59 years, 57% with chronic pain) and 22 elderly (≥60 years, 46% with chronic pain) survivors of moderate-to-severe TBI. TBI-P participants exhibited significant alterations in heat and pressure pain sensitivity compared to TBI-NP participants, with more pronounced decreases in heat detection in the elderly group and increased warmth sensitivity in the young group. Alterations were not always associated with chronic pain, as cold hypoesthesia was found in elderly TBI-NP participants. In both age groups, chronic pain was associated with higher levels of depressive mood. Conclusions: Results suggest that young and elderly TBI survivors have both common and unique sensory properties, highlighting the need to pursue sensory testing studies in older patient groups. Depression might also be an important target for pain management after TBI.

Background Total shoulder arthroplasty with second generation porous tantalum glenoid implants (Trabecular Metal™) has shown good short-term outcomes, but mid-term outcomes are unknown. This study describes the clinical, radiographic, and patient-rated mid-term outcomes of total shoulder arthroplasty utilizing cemented Trabecular Metal™ glenoid components. Methods Patients who underwent anatomic total shoulder arthroplasty with cemented Trabecular Metal™ glenoid components for primary osteoarthritis were identified for minimum five-year follow-up. The primary outcome measure was implant survival; secondary outcome measures included patient-rated outcome scores, shoulder range of motion findings, and radiographic analysis. Results Twenty-seven patients were enrolled in the study. Twenty-one patients had full radiographic follow-up. Mean follow-up was 6.6 years. There was 100% implant survival. Shoulder range of motion significantly improved and the mean American Shoulder and Elbow Society score was 89.8. There was presence of metal debris radiographically in 24% of patients. Twenty-nine percent of patients had evidence of radiolucency. Fourteen percent of patients had moderate superior subluxation. Conclusion Total shoulder arthroplasty with second generation cemented Trabecular Metal™ glenoid components yielded good outcomes at mean 6.6-year follow-up. Metal debris incidence and clinical outcomes were similar to short-term findings. The presence of metal debris did not significantly affect clinical outcomes. Continued observation of these patients will elucidate longer-term implant survival.

Published: March 2020

Background Respiratory epithelial adenomatoid hamartoma (REAH) is a benign lesion of the sinonasal tract that may mimic more concerning pathology. Clinical factors associated with REAH have not been well characterized. Objective To report our findings on patients with this pathologic diagnosis. Methods A retrospective chart review of patients with REAH between September 2006 and November 2019 was conducted. Data collected included clinical allergic rhinitis and asthma history, additional sinonasal diagnoses, prior sinus surgery, and the location of the REAH within the sinonasal cavity. Results Twenty-six patients were identified (53.8% male, mean age 62 years [range, 29–93]). Bilateral REAH occurred in 50%. REAH was located at the superior nasal septum in 84.6% cases, with the remainder identified in sinus contents submitted for pathology, making definitive site uncertain. Concurrent sinonasal inflammatory disorders were identified in 18 patients (69.2%), including chronic rhinosinusitis with nasal polyps—not otherwise specified (6), chronic rhinosinusitis without nasal polyps (4), aspirin-exacerbated respiratory disease (2), allergic fungal rhinosinusitis (1), central compartment atopic disease (5), and IgG4-related sclerosing disease (1). Eight patients had isolated REAH. Adequate allergy records were available for 19 patients, of which 18 of 19 (94.7%) had clinical allergic rhinitis. Conclusions REAH is a benign sinonasal lesion commonly located within the central compartment of the nasal cavity, a site of significant allergen exposure. Affected patients have a high incidence of allergy along with chronic inflammatory conditions. The coexistence of REAH within inflammatory nasal mucosa in a consistent anatomic location, suggests REAH may have a similar etiology to central compartment atopic disease, with resultant respiratory glandular ingrowth within long-standing reactive changes of mucosa derived from ethmoid embryologic origin.

Background Left ventricular ejection fraction (LVEF) is generally measured by echocardiography but is increasingly available with myocardial perfusion scintigraphy. With myocardial perfusion scintigraphy, the threshold of LVEF below which there is a risk for myocardial infarct or sudden cardiac death is higher for women (51%) than for men (43%). We tested the hypothesis that such a sex difference may also occur with echocardiography and myocardial perfusion scintigraphy. Methods Four hundred and four men, mean age = 67.7 ± SD = 12.3 yr; 339 women, 67.7 ± 11.7 yr had separate myocardial perfusion scintigraphy and echocardiography examinations within six months. A subset of 327 of these patients (181 men, 68.8 ± 12.1 yr; 146 women, 66.4 ± 12.1 yr) had examinations within one month and were additionally analysed as this sub-group. Myocardial perfusion scintigraphy and echocardiography were used to measure LVEF at rest and their agreement (neither considered as a reference method) was assessed by Bland–Altman plots: LVEF difference (myocardial perfusion scintigraphy minus echocardiography ) against average LVEF ([Formula: see text]). Results Of patients who had myocardial perfusion scintigraphy and echocardiography performed within six months, mean LVEF difference = +1.1% (95% limits of agreement: −19.3 to +21.6) in men but +10.9% (−10.7 to +32.5) in women. LVEF difference diverged from zero marginally in men (mean difference = +1.1, 95%CI  = +0.1 to +2.1, p =  0.028) but more in women (+10.9, +9.8 to +12.1, p < 0.001). The LVEF difference correlated with average LVEF itself in both men ( r =  0.305, p < 0.001) and women ( r =  0.361, p < 0.001), and with age in women ( r = 0.117, p = 0.031). Similar results were observed for the subset. Conclusions Caution should be taken when interpreting LVEF measured by different techniques due to their wide limits of agreement and systematic bias, more markedly in women.

Published: March 2020

Introduction: Opioid-related adverse drug events (ORADEs) are an increasingly recognized complication associated with the common prescription of opioids after orthopedic surgery. In this study, we attempted to understand how potential ORADEs following hip replacement surgery in older patients affected hospital length of stay, hospital revenue, and their association with specific risk factors and clinically relevant diseases occurring during hospitalization. Methods: We conducted a retrospective study using the Centers for Medicare and Medicaid Services Administrative Database to analyze Medicare discharges after hip replacement surgery to identify potential ORADEs. The impact of potential ORADEs on mean hospital length of stay (LOS) and hospital revenue was analyzed. Results: The potential ORADE rate in patients who underwent hip replacement surgery was 8.6%. The mean LOS for discharges with a potential ORADE was 1.41 days longer than that for discharges without an ORADE. The mean hospital revenue per day with a potential ORADE was US$1708 less than without an ORADE. Potential ORADEs were also found to be strongly associated with poor patient outcomes such as pneumonia, septicemia, and shock. Discussion: Potential ORADEs in hip replacement surgery in older patients are associated with longer hospitalizations, decreased hospital revenue per day, certain patient risk factors, and clinically relevant diseases occurring during hospitalizations. Our finding of an association between potential ORADEs and decreased hospital revenue per day may be attributed to the management of these adverse events, as a patient may need to undergo additional testing, may need additional treatment regimens, and may need a higher level of care. Conclusion: By reducing the use of opioids and employing a multimodal analgesic approach, we may improve patient care, decrease hospital lengths of stay, and increase hospital revenue

Authors: Barakat Ahmed , Mansy Yasser El , Saghir Hesham El 
Published: March 2020

Study Design: This was a prospective cohort study. Objectives: To introduce the iliac connectors as fixation options in spinal constructs used for correction of severe scoliosis at locations other than the lumbopelvic region. Methods: Nine patients with severe rigid scoliosis undergoing surgical release and posterior instrumentation in the period between January 2013 and January 2015 were included in this prospective cohort study. Mean age was 18.4 years; 8 had triple structural curves, and the remaining patient had double structural curves. Cobb angles of the primary and compensatory curves were compared with the immediate, 1-year, and 2-year postoperative measurements using the F test, with P value ≤.05 indicating statistical significance. Screw densities of the final constructs were calculated and compared with the screw densities when the offset iliac connectors were not used. Results: One to 4 offset iliac connectors were used in all 9 patients, increasing screw density by a mean of 6.24 ( P < .001). The mean Cobb angle of the major curve was corrected from 98.44° to 58.2° ( P < .001), that of the first compensatory curve, from 56.55° to 38.33° ( P < .001), and that of the second compensatory curve, from 40.75° to 26.63° ( P < .001). There were no intraoperative neurological complications. After a mean follow-up of 30.6 months, the construct remained stable in all patients with no loss of correction. Conclusion: Offset iliac connectors can be a valuable tool to increase screw density in correction of severe scoliosis, thus increasing overall biomechanical strength of the final construct.

Published: March 2020

Purpose: The purpose of this study was to assess the effectiveness of periarticular multidrug infiltration (PMDI) and compare it with that of epidural catheter use. Methods: Fifty-eight patients (58 joints) who underwent total knee arthroplasty were included in this single-center, prospective, parallel, randomized, controlled trial. Preoperatively, patients were randomly categorized into the PMDI and epidural catheter groups. We evaluated postoperative pain (visual analog scale (VAS) and narcotic consumption), functional outcomes (range of motion (ROM) of knee flexion, the day patients could perform the straight-leg raising (SLR) test, and day of starting cane use), and laboratory data (white blood cell (WBC) and C-reactive protein (CRP)). Results: There was no significant difference in the VAS score, ROM of knee flexion, the day patients could do SLR, and the day of starting cane use between the PMDI and epidural catheter groups. However, the PMDI group could perform SLR on a postoperative day (POD) 1 ( p < 0.05). WBC level on POD 1 was significantly higher in the PMDI group ( p < 0.05), whereas the CRP levels on POD 1 ( p < 0.01), 3 ( p < 0.01), and 5 ( p < 0.01) were significantly lower in the PMDI group than in the epidural catheter group. The frequency of side effects was not significantly different between the groups. Conclusion: PMDI was as effective as epidural catheter use for pain control. A higher percentage of patients who underwent PMDI could perform SLR on POD 1; therefore, the functional recovery was earlier in the PMDI group than in the epidural catheter group. PMDI may suppress inflammation in the whole body because of steroids.
